C reactive protein (CRP) has linked with long-term risk of recurrent cardiovascular events or death. Albumin, in contrast to CRP known as a negative acute-phase protein. Thus a newly introduced marker assessed relation of CRP to albumin ratio (CAR), which may provide better results than the use of either marker alone. The aim of the study is to assess the association of C-reactive protein to albumin ratio (CAR) with in-hospital short-term major adverse cardiac events (MACEs) in acute coronary syndrome (ACS) patients. Patients & Methods: A multi-centers prospective cohort study was conducted at coronary intensive care units (CICU) in Baghdad during the period from March to October 2021 that included a total of 132 patients who were diagnosed as a case of ACS. They were assessed for major adverse cardiac events (MACEs) like cardiogenic shock, arrhythmias, post-MI angina, and acute heart failure while inside the ward, in addition to need for early interventional therapeutic approach in relation to (CAR) immediately at time of admission to hospital. Results: High values of CAR, whether using hs-CRP or CRP, were identified as an independent predictor for in-hospital MACEs (P value Conclusion: The CAR was independently correlated with in-hospital short-term MACEs and can be used for risk stratification in patients with ACS.展开更多

In the present study, we aimed to investigate the association between circulating levels of high sensitive C-reactive protein (hs-CRP) and various biomarkers for hepatic, diabetic, and cardiovascular health. The retrospective analysis included 438 individuals who were tested for these panels simultaneously at Vibrant America Clinical Laboratory. The study population included free-living individuals without any preexisting clinical conditions. Among the cardiovascular markers, a positive correlation and significant association was found between high levels of hs-CRP and serum levels of triglycerides (r = 0.0964, p −0.1423, p −0.1216, p < 0.0105) with circulating levels of hs-CRP. Among all the diabetic markers, glucose (r = 0.1547, p < 0.0011) and glycated serum protein (r = 0.1725, p < 0.0003) were positively correlated with circulating hs-CRP. In the hepatic panel, AST, a transaminase that plays a vital role in amino acid metabolism, was found to have a strong positive correlation with hs-CRP (r = 0.2139, p < 0.0001). In conclusion, the results clearly show the association of hs-CRP with diabetic, hepatic, and cardiovascular risk factors indicating its central value as a key marker for several lifestyle-associated disorders.展开更多
Metabolic syndrome (MetS) and its components have been linked to elevated serum levels of inflammatory biomarkers such as C-reactive protein, interleukin-6, interleukin-1β and tumor necrosis factor alpha. The aim of ...Metabolic syndrome (MetS) and its components have been linked to elevated serum levels of inflammatory biomarkers such as C-reactive protein, interleukin-6, interleukin-1β and tumor necrosis factor alpha. The aim of our study was to address the association between MetS components with serum hs-CRP and IL-6 levels among Congolese adults. A total of 357 participants (aged 30 - 87 years) were included in this cross-sectional study. Anthropometrics were collected and fasting blood sampled for assessment of fasting blood glycaemia (FBG), lipids and inflammatory parameters using commercially available assays. NCEP-ATPIII criteria were used to define MetS. The Median (IQR) hs-CRP and IL-6 levels were higher in participants with MetS than in those without ([7 (4, 14) versus 6 (4, 8)] mg/L;p = 0.092 and [23.8 (20.9, 27.6) versus 22.3 (19.5, 25.0)] pg/mL;p = 0.002). hs-CRP and IL-6 levels were significantly higher in females with MetS than in those without, but not in males. Among participants, only TG was correlated with hs-CRP (r = 0.149, p = 0.007), and a significant correlation was observed between TG (r = 0.116, p = 0.037), FBG (r = 0.208, p = 0.000), HDL-C (r = −0.119, p = 0.034) and SBP (r = 0.143, p = 0.010) and IL-6. In males, hs-CRP levels were positively correlated with TG (0.316;p = 0.000), negatively with HDL-C (r = −0.290, p = 0.0022), without such correlations in females. In Ames, IL-6 levels were positively correlated with FBG (r = 0.202;p = 0.035), and negatively with HDL-C (r = −0.249, p = 0.009). Significant correlations between IL-6 levels and FBG (r = 0.214;p = 0.000) or SBP (r = 0.227, p = 0.000) were observed in females. Logistic regression analysis was carried out to identify the relationship between MetS components and hs-CRP or IL-6. Values of area under receiver-operating characteristic (ROC) curves suggest potential use of serum hs-CRP (AUC = 0.675) and IL-6 (AUC = 0.656) as diagnostic biomarkers of MetS. Combination of hs-CRP and IL-6 improved diagnosis accuracy, yielding a 0.698 ROC curve area. MetS components are associated with hs-CRP and IL-6 levels among adults Congolese. Combining the two biomarkers hs-CRP and IL-6 improves Mets diagnostic accuracy compared to hs-CRP or IL-6 alone.展开更多

Only UVA and UVB manage to penetrate the ozone layer, but due to anthropological activities, all of them are capable of interacting with humans to a greater or lesser extent, and can generate adverse effects such as cellular stress when interacting with intra-and extracellular biomolecules. The skin is the first organ in contact with UV radiation, and the stress it generates can be analyzed by the expression of a bioindicator of cellular damage such as Hsp70. Therefore, the objective of the project was: to determine the effect of UVA, UVB and UVC radiation on HaCaT epithelial cells, by analyzing the expression of Hsp70. Materials and methods: HaCaT cells were cultured in vitro, which were irradiated with UVA, UVB and UVC light at different doses, to subsequently determine the degree of Hsp70 expression by Immunodetection by PAGE-SDS and Western Blot. Results: Basal expression of Hsp70 was observed in no irradiated HaCaT cells. When HaCaT cells were irradiated with UVA, UVB, UVC, an increase in this Hsp70 protein was observed. With UVA, a higher degree of expression was observed at a time of 30 minutes of irradiation. With UVB the highest expression shifted to a time of 20 minutes. With UVC, overexpression was observed after 10 minutes. Conclusion: UV radiation generates cellular stress on HaCaT cells, evaluated by the stress bioindicator Hsp70. According to the wavelength of UV radiation, those that have a shorter wavelength have a greater potential for cellular damage, such as UVC.展开更多

METHODS: The endpoints of antibiotic treatment in 46 patients with pyogenic liver abscess after complete percutaneous drainage were assessed by performing a retrospective study. After complete percutaneous drainage, normal CRP values were considered as the endpoint in 18 patients (experimental group), and normal body temperature for at least 2 wk were considered as the endpoints in the other 28 patients (control group). RESULTS:The duration of antibiotic treatment after complete percutaneous drainage was 15.83 ± 6.45 d and 24.25 ± 8.18 d for the experimental and the control groups, respectively (P=0.001), being significantly shorter in the experimental group than in the control group. The recurrence rate was 0% for both groups.However, we could not obtain the follow-up data about 3 patients in the control group. CONCLUSION: CRP values can be considered as an independent factor to determine the duration of the antibiotic treatment for pyogenic liver abscess after complete percutaneous drainage.展开更多

Daily venous plasma CRP levels were measured for up to 7 d following the procedure(or up to discharge). Procedural factors and 30-d safety outcomes according tothe Valve Academic Research Consortium 2 definition were collected. RESULTS: Following TAVI, CRP significantly increased reaching a peak on day 3 of 87.6 ± 5.5 mg/d L, P < 0.001. Patients who developed clinical signs and symptoms of sepsis had significantly increased levels of CRP(P < 0.001). The presence of diabetes mellitus was associated with a significantly higher peak CRP level at day 3(78.4 ± 3.2 vs 92.2 ± 4.4, P < 0.001). There was no difference in peak CRP release following balloonexpandable or self-expandable TAVI implantation(94.8 ± 9.1 vs 81.9 ± 6.9, P = 0.34) or if post-dilatation was required(86.9 ± 6.3 vs 96.6 ± 5.3, P = 0.42), however, when pre-TAVI balloon aortic valvuloplasty was performed this resulted in a significant increase in the peak CRP(110.1 ± 8.9 vs 51.6 ± 3.7, P < 0.001). The development of a major vascular complication did result in a significantly increased maximal CRP release(153.7 ± 11.9 vs 83.3 ± 7.4, P = 0.02) and there was a trend toward a higher peak CRP following major/lifethreatening bleeding(113.2 ± 9.3 vs 82.7 ± 7.5, P = 0.12) although this did not reach statistical significance. CRP was not found to be a predictor of 30-d mortality on univariate analysis. CONCLUSION: Careful attention should be paid to baseline clinical characteristics and procedural factors when interpreting CRP following TAVI to determine their future management.展开更多

OBJECTIVE: To observe the differences of blood glucose, lipid, homocysteine and previous disease history among patients with acute cerebral infarction at various levels of hs-CRP and compare changes of hs-CRP of patients with various degrees of neurologic impairment. DESIGN: Contrast observation. SETTING: Department of Neurology, Shenzhou Hospital, Shenyang Medical College. PARTICIPANTS: A total of 102 patients with acute cerebral infarction were selected from Department of Neurology, Shenzhou Hospital of Shenyang Medical College from February 2005 to September 2006, including 55 males and 47 females aged from 55 to 86 years. All accepted patients met the diagnostic criteria of cerebral infarction established by the Fourth National Cerebrovascular Disease Academic Meeting and were diagnosed with CT or MRI examination. All patients provided the confirmed consent. Based on clinical criteria of neurologic impairment established by the Fourth National Cerebrovascular Disease Academic Meeting, patients were randomly divided into mild group (0–15 points, n =46), moderate group (16–30 points, n =38) and severe group (31–45 points, n =18). In addition, based on hs-CRP level within 72 hours, patients were divided into normal group (hs-CRP ≤ 3 mg/L, n =53) and increasing group (hs-CRP > 3 mg/L, n =49). METHODS: ① 2 mL venous blood was selected from hospitalized patients in the next morning to separate serum. Quantitative measurement of hs-CRP was dealt with Latex Enhnced Turbidimetric Immunoassay (LETIA). ② Fasting venous blood was colleted from hospitalized patients in the next morning to measure numeration of white blood cells, fibrinogen, blood glucose, total cholesterol (TC), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and homocysteine. ③ Measurement data were compared with t test or analysis of variance. MAIN OUTCOME MEASURES: ① Comparisons of serum biochemical indexes among patients with various levels of hs-CRP; ② comparisons of risk factors among patients with various levels of hs-CRP; ③ comparisons of levels of hs-CRP among patients with various degrees of clinical neurologic impairment. RESULTS: A total of 102 patients were involved in the final analysis. ① Plasma fibrinogen and numeration of leucocytes were more in the increasing group than those in the normal group (t =4.39, 3.54, P < 0.01); while, there were no significant differences of blood glucose, TC, TG, HDL-C, LDL-C and homocysteine between the two groups (P > 0.05). ② Percentage of patients with hypertension and diabetes mellitus (DM) was higher in the increasing group than the normal group (χ2=3.98, 4.23, P < 0.05); while, percentage of patients with smoking in the increasing group was not significantly different from that of patients in the normal group (P > 0.05). ③ Level of hs-CRP of patients with severe neurologic impairment was higher than that of patients with moderate neurologic impairment (t =2.273, P < 0.05); that of patients with moderate neurologic impairment was higher than that of patients with mild neurologic impairment (t =2.586, P < 0.05); that of patients with severe neurologic impairment was obviously higher than that of patients with mild neurologic impairment (t = 4.913, P < 0.01). CONCLUSION: ① With the increase of hs-CRP, plasma fibrinogen and numeration of leucocytes of patients with acute cerebral infarction is increased, especially, they are increased remarkably among patients who have history of diabetes mellitus and hypertension. ② Increase of level of hs-CRP can be regarded asone of marks to evaluate severity of acute stroke.展开更多

OBJECTIVE: To observe the effects and clinical significance of C-reactive protein in patients with craniocerebral injury after hyperbaric oxygenation. DESIGN: Randomized controlled study. SETTING: Departments of Neurosurgery, Laboratory and Hyperbaric Oxygen, the Second Affiliated Hospital, Medical College of Shantou University. PARTICIPANTS: A total of 60 patients with craniocerebral injury were selected from Department of Neurosurgery, the Second Affiliated Hospital, Medical College of Shantou University from October 2006 to April 2007. There were 37 males and 23 females and the mean age was 26 years. All subjects were certainly diagnosed as history of craniocerebral injury. Patients hospitalized at 24 hours after injury, Glasgow Coma Score ranged from 3 to 12 points, and all patients were certainly diagnosed with CT or MR scanning. Patients and their relatives provided confirmed consent. All the subjects were randomly divided into hyperbaric oxygenation group and control group with 30 in each group. METHODS: Patients in the control group were treated with routinely neurosurgical therapy after hospitalization; however, based the same basic treatment in the control group, patients in the hyperbaric oxygenation group received hyperbaric oxygenation by using iced-wheel four-door 2-cabin air-compression chamber (made in Yantai) from 24 hours to 10 days after operation or injury. After entering the cabin, patients who had a clear consciousness breathed the oxygen by using face mask; contrarily, patients directly breathed the oxygen. Therapeutic project: Expression was increased for about 15–20 minutes, maintained for about 70–80 minutes, and decreased for 20 minutes. Otherwise, pressure was maintained from 0.2 to 0.25 MPa. Hyperbaric oxygenation took an hour for once a day and 10 times were regarded as a course. Venous blood was collected before treatment and on the next day of the first course end. Content of C-reactive protein in plasma was measured with immune turbidimetry in hyperbaric oxygenation group; in addition, content of C-reactive protein in plasma was directly measured with the same method at the corresponding time in the control group. If the content was less or equal to 8 mg/L, it was regarded as normal value. Effects of the two groups were evaluated based on Glasgow Coma Score before and after treatment. MAIN OUTCOME MEASURES: Content of plasma C-reactive protein and Glasgow Coma Score in the two groups before and after treatment. RESULTS: All 60 patients were involved in the final analysis. ① Content of plasma C-reactive protein: The two contents were obviously higher than normal value after craniocerebral injury. There was no significant difference in the two groups before treatment (P > 0.05), but both contents were decreased after treatment, and there was significant difference between HBOT group and control group after treatment (t =4.756, P < 0.01). In addition, there was significant difference in hyperbaric oxygen therapy group before and after treatment (t =5.236, P < 0.01). ② Glasgow Coma Score: There was no significant difference in the two groups before treatment (P > 0.05), but scores were increased in both groups after treatment (t =9.92, 2.51, P < 0.01, 0.05); on the other hand, therefore, there was significant difference between the two groupsafter treatment (t =9.21, P < 0.01). CONCLUSION: Hyperbaric oxygenation can remarkably decrease content of plasma C-reactive protein in patients with craniocerebral injury at the phase of stress.展开更多

Methods A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios(HRs) and 95% confidence intervals(CIs) for ischemic stroke among all groups. Results The multivariate adjusted HRs(95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46(0.89-2.39) and 1.63(0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs(95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04(0.46-2.35), 1.06(0.58-1.95) and 2.52(1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant. Conclusion We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.展开更多
文摘Background: Acute coronary syndrome (ACS) is the leading cardiovascular (CV) cause of mortality. C reactive protein (CRP) has linked with long-term risk of recurrent cardiovascular events or death. Albumin, in contrast to CRP known as a negative acute-phase protein. Thus a newly introduced marker assessed relation of CRP to albumin ratio (CAR), which may provide better results than the use of either marker alone. The aim of the study is to assess the association of C-reactive protein to albumin ratio (CAR) with in-hospital short-term major adverse cardiac events (MACEs) in acute coronary syndrome (ACS) patients. Patients & Methods: A multi-centers prospective cohort study was conducted at coronary intensive care units (CICU) in Baghdad during the period from March to October 2021 that included a total of 132 patients who were diagnosed as a case of ACS. They were assessed for major adverse cardiac events (MACEs) like cardiogenic shock, arrhythmias, post-MI angina, and acute heart failure while inside the ward, in addition to need for early interventional therapeutic approach in relation to (CAR) immediately at time of admission to hospital. Results: High values of CAR, whether using hs-CRP or CRP, were identified as an independent predictor for in-hospital MACEs (P value Conclusion: The CAR was independently correlated with in-hospital short-term MACEs and can be used for risk stratification in patients with ACS.
文摘Biomarkers are early predictors of various disorders, circulating level of C-reactive protein is a sensitive biomarker of systemic inflammation and may also be associated with the development of diabetic, hepatic, and cardiovascular diseases. In the present study, we aimed to investigate the association between circulating levels of high sensitive C-reactive protein (hs-CRP) and various biomarkers for hepatic, diabetic, and cardiovascular health. The retrospective analysis included 438 individuals who were tested for these panels simultaneously at Vibrant America Clinical Laboratory. The study population included free-living individuals without any preexisting clinical conditions. Among the cardiovascular markers, a positive correlation and significant association was found between high levels of hs-CRP and serum levels of triglycerides (r = 0.0964, p −0.1423, p −0.1216, p < 0.0105) with circulating levels of hs-CRP. Among all the diabetic markers, glucose (r = 0.1547, p < 0.0011) and glycated serum protein (r = 0.1725, p < 0.0003) were positively correlated with circulating hs-CRP. In the hepatic panel, AST, a transaminase that plays a vital role in amino acid metabolism, was found to have a strong positive correlation with hs-CRP (r = 0.2139, p < 0.0001). In conclusion, the results clearly show the association of hs-CRP with diabetic, hepatic, and cardiovascular risk factors indicating its central value as a key marker for several lifestyle-associated disorders.
文摘Metabolic syndrome (MetS) and its components have been linked to elevated serum levels of inflammatory biomarkers such as C-reactive protein, interleukin-6, interleukin-1β and tumor necrosis factor alpha. The aim of our study was to address the association between MetS components with serum hs-CRP and IL-6 levels among Congolese adults. A total of 357 participants (aged 30 - 87 years) were included in this cross-sectional study. Anthropometrics were collected and fasting blood sampled for assessment of fasting blood glycaemia (FBG), lipids and inflammatory parameters using commercially available assays. NCEP-ATPIII criteria were used to define MetS. The Median (IQR) hs-CRP and IL-6 levels were higher in participants with MetS than in those without ([7 (4, 14) versus 6 (4, 8)] mg/L;p = 0.092 and [23.8 (20.9, 27.6) versus 22.3 (19.5, 25.0)] pg/mL;p = 0.002). hs-CRP and IL-6 levels were significantly higher in females with MetS than in those without, but not in males. Among participants, only TG was correlated with hs-CRP (r = 0.149, p = 0.007), and a significant correlation was observed between TG (r = 0.116, p = 0.037), FBG (r = 0.208, p = 0.000), HDL-C (r = −0.119, p = 0.034) and SBP (r = 0.143, p = 0.010) and IL-6. In males, hs-CRP levels were positively correlated with TG (0.316;p = 0.000), negatively with HDL-C (r = −0.290, p = 0.0022), without such correlations in females. In Ames, IL-6 levels were positively correlated with FBG (r = 0.202;p = 0.035), and negatively with HDL-C (r = −0.249, p = 0.009). Significant correlations between IL-6 levels and FBG (r = 0.214;p = 0.000) or SBP (r = 0.227, p = 0.000) were observed in females. Logistic regression analysis was carried out to identify the relationship between MetS components and hs-CRP or IL-6. Values of area under receiver-operating characteristic (ROC) curves suggest potential use of serum hs-CRP (AUC = 0.675) and IL-6 (AUC = 0.656) as diagnostic biomarkers of MetS. Combination of hs-CRP and IL-6 improved diagnosis accuracy, yielding a 0.698 ROC curve area. MetS components are associated with hs-CRP and IL-6 levels among adults Congolese. Combining the two biomarkers hs-CRP and IL-6 improves Mets diagnostic accuracy compared to hs-CRP or IL-6 alone.

文摘Neuroinflammation and the NACHT,LRR,and PYD domains-containing protein 3 inflammasome play crucial roles in secondary tissue damage following an initial insult in patients with traumatic brain injury(TBI).Maraviroc,a C-C chemokine receptor type 5 antagonist,has been viewed as a new therapeutic strategy for many neuroinflammatory diseases.We studied the effect of maraviroc on TBI-induced neuroinflammation.A moderate-TBI mouse model was subjected to a controlled cortical impact device.Maraviroc or vehicle was injected intraperitoneally 1 hour after TBI and then once per day for 3 consecutive days.Western blot,immunohistochemistry,and TUNEL(terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling)analyses were performed to evaluate the molecular mechanisms of maraviroc at 3 days post-TBI.Our results suggest that maraviroc administration reduced NACHT,LRR,and PYD domains-containing protein 3 inflammasome activation,modulated microglial polarization from M1 to M2,decreased neutrophil and macrophage infiltration,and inhibited the release of inflammatory factors after TBI.Moreover,maraviroc treatment decreased the activation of neurotoxic reactive astrocytes,which,in turn,exacerbated neuronal cell death.Additionally,we confirmed the neuroprotective effect of maraviroc using the modified neurological severity score,rotarod test,Morris water maze test,and lesion volume measurements.In summary,our findings indicate that maraviroc might be a desirable pharmacotherapeutic strategy for TBI,and C-C chemokine receptor type 5 might be a promising pharmacotherapeutic target to improve recovery after TBI.
文摘Ultraviolet radiation by its wavelength is divided into: UVA, UVB and UVC. Only UVA and UVB manage to penetrate the ozone layer, but due to anthropological activities, all of them are capable of interacting with humans to a greater or lesser extent, and can generate adverse effects such as cellular stress when interacting with intra-and extracellular biomolecules. The skin is the first organ in contact with UV radiation, and the stress it generates can be analyzed by the expression of a bioindicator of cellular damage such as Hsp70. Therefore, the objective of the project was: to determine the effect of UVA, UVB and UVC radiation on HaCaT epithelial cells, by analyzing the expression of Hsp70. Materials and methods: HaCaT cells were cultured in vitro, which were irradiated with UVA, UVB and UVC light at different doses, to subsequently determine the degree of Hsp70 expression by Immunodetection by PAGE-SDS and Western Blot. Results: Basal expression of Hsp70 was observed in no irradiated HaCaT cells. When HaCaT cells were irradiated with UVA, UVB, UVC, an increase in this Hsp70 protein was observed. With UVA, a higher degree of expression was observed at a time of 30 minutes of irradiation. With UVB the highest expression shifted to a time of 20 minutes. With UVC, overexpression was observed after 10 minutes. Conclusion: UV radiation generates cellular stress on HaCaT cells, evaluated by the stress bioindicator Hsp70. According to the wavelength of UV radiation, those that have a shorter wavelength have a greater potential for cellular damage, such as UVC.

文摘BACKGROUND The NOD-like receptor family pyrin domain-containing 3(NLRP3)inflammasome is a significant component of the innate immune system that plays a vital role in the development of various parasitic diseases.However,its role in hepatic alveolar echinococcosis(HAE)remains unclear.AIM To investigate the NLRP3 inflammasome and its mechanism of activation in HAE.METHODS We assessed the expression of NLRP3,caspase-1,interleukin(IL)-1β,and IL-18 in the marginal zone and corresponding normal liver of 60 patients with HAE.A rat model of HAE was employed to investigate the role of the NLRP3 inflammasome in the marginal zone of HAE.Transwell experiments were conducted to investigate the effect of Echinococcus multilocularis(E.multilocularis)in stimulating Kupffer cells and hepatocytes.Furthermore,immunohistochemistry,Western blotting,and enzyme-linked immunosorbent assay were used to evaluate NLRP3,caspase-1,IL-1β,and IL-18 expression;flow cytometry was used to detect apoptosis and reactive oxygen species(ROS).RESULTS NLRP3 inflammasome activation was significantly associated with ROS.Inhibition of ROS production decreased NLRP3-caspase-1-IL-1βpathway activation and mitigated hepatocyte damage and inflammation.CONCLUSION E.multilocularis induces hepatocyte damage and inflammation by activating the ROS-mediated NLRP3-caspase-1-IL-1βpathway in Kupffer cells,indicating that ROS may serve as a potential target for the treatment of HAE.

文摘Catalytic hydrogenation of CO_(2) using renewable hydrogen not only reduces greenhouse gas emissions,but also provides industrial chemicals.Herein,a Co-Fe bimetallic catalyst was developed by a facile reactive ball-milling method for highly active and selective hydrogenation of CO_(2) to value-added hydrocarbons.When reacted at 320℃,1.0 MPa and 9600 mL h^(-1) g_(cat)^(-1),the selectivity to light olefin(C_(2)^(=)-C_(4)^(=)) and C_(5)+ species achieves 57.3% and 22.3%,respectively,at a CO_(2) co nversion of 31.4%,which is superior to previous Fe-based catalysts.The CO_(2) activation can be promoted by the CoFe phase formed by reactive ball milling of the Fe-Co_(3)O_(4) mixture,and the in-situ Co_(2)C and Fe_(5)C_(2) formed during hydrogenation are beneficial for the C-C coupling reaction.The initial C-C coupling is related to the combination of CO species with the surface carbon of Fe/Co carbides,and the sustained C-C coupling is maintained by self-recovery of defective carbides.This new strategy contributes to the development of efficient catalysts for the hydrogenation of CO_(2) to value-added hydrocarbons.

文摘This study examined the role of high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6) and cystatin C in ischemic stroke complicating atrial fibrillation (AF) and the relationship of systemic inflammation with this disease in order to identify AF patients who are at high risk of stroke and need optimal anticoagulant therapy.A total of 103 AF patients, simple (n=75) or complicated by ischemic stroke (n=28), and 112 control subjects were recruited.IL-6 level was detected by using enzyme linked immunosorbent assay.Cystatin C and hsCRP levels were measured by means of a particle-enhanced immunonephelometric assay.The results showed that the AF patients had higher levels of hsCRP (P=0.004), IL-6 (P=0.000), and cystatin C (P=0.000) than control subjects.Plasma hsCRP level was increased in the AF patients with ischemic stroke as compared to the patients with simple AF (P=0.036).The AF patients who had the level of hsCRP exceeding 3.83 mg/L were at a higher risk than those with hsCRP level lower than 3.83 mg/L (P=0.030).After adjusting for other factors, cystatin C remained positively associated with IL-6 (r=0.613) and hsCRP (r=0.488).It was concluded that hsCRP is positively correlated with ischemic stroke complicating AF and may be a risk factor independent of other risk factors for AF.Elevated cystatin C level is also indicative of the increased risk of AF.

文摘Increased plasma total homocysteine (tHcy) and high sensitivity C-reactive protein (hsCRP) levels are independent risk factors for cardiovascular disease.However, the predictive value of tHcy in combination with hsCRP in patients with stroke is not known.To determine the relationship between tHcy and hsCRP, we enrolled 291 patients with first-onset stroke (196 ischemic and 95 hemorrhagic).Plasma tHcy and hsCRP levels were measured and subsequent vascular events and deaths were determined over a 5-year period.Using the arbitrary cutoff for tHcy (<18 μmol/L and ≥18 μmol/L) and hsCRP (<1 mg/L, 1-3 mg/L and >3 mg/L), the patients were divided into 6 groups.Survival analysis showed that the probability of death or new vascular events during a 5-year follow-up increased according to tHcy and hsCRP levels (P<0.01).The relative risk (RR) of death or new vascular events was 4.67 (95% CI, 1.96 to 11.14, P=0.001) in patients with high tHcy (≥18 μmol/L) and hsCRP (>3 mg/L) compared with those with low tHcy (<18 μmol/L) and hsCRP (<1 mg/L).The increased tHcy level (≥18 μmol/L) combined with increased hsCRP level (>3 mg/L) was still significantly associated with the risk of death or new vascular events (RR, 4.10, 95% CI, 1.61 to 10.45, P=0.003) even when adjusted for other risk factors at inclusion.The combination of increased tHcy and hsCRP levels had a stronger predictive value than increased hsCRP alone or increased tHcy level alone.Further studies are required to evaluate the potential decrease in risks associated with lowering both Hcy and hsCRP levels in patients that present with both increased tHcy and hsCRP.
文摘BACKGROUND:Serum C-reactive protein(CRP) increases and albumin decreases in patients with inflammation and infection.However,their role in patients with acute pancreatitis is not clear.The present study was to investigate the predictive significance of the CRP/albumin ratio for the prognosis and mortality in acute pancreatitis patients.METHODS:This study was performed retrospectively with 192 acute pancreatitis patients between January 2002 and June 2015.Ranson scores,Atlanta classification and CRP/albumin ratios of the patients were calculated.RESULTS:The CRP/albumin ratio was higher in deceased patients compared to survivors.The CRP/albumin ratio was positively correlated with Ranson score and Atlanta classification in particular and with important prognostic markers such as hospitalization time,CRP and erythrocyte sedimentation rate.In addition to the CRP/albumin ratio,necrotizing pancreatitis type,moderately severe and severe Atlanta classification,and total Ranson score were independent risk factors of mortality.It was found that an increase of 1 unit in the CRP/albumin ratio resulted in an increase of 1.52 times in mortality risk.A prediction value about CRP/albumin ratio >16.28 was found to be a significant marker in predicting mortality with 92.1% sensitivity and 58.0% specificity.It was seen that Ranson and Atlanta classification were higher in patients with CRP/albumin ratio >16.28 compared with those with CRP/albumin ratio ≤16.28.Patients with CRP/albumin ratio >16.28 had a 19.3 times higher chance of death.CONCLUSION:The CRP/albumin ratio is a novel but promising,easy-to-measure,repeatable,non-invasive inflammationbased prognostic score in acute pancreatitis.
文摘AIM:To investigate the clinical signifi cance of C-reactive protein (CRP) values in determining the endpoint of antibiotic treatment for liver abscess after drainage. METHODS: The endpoints of antibiotic treatment in 46 patients with pyogenic liver abscess after complete percutaneous drainage were assessed by performing a retrospective study. After complete percutaneous drainage, normal CRP values were considered as the endpoint in 18 patients (experimental group), and normal body temperature for at least 2 wk were considered as the endpoints in the other 28 patients (control group). RESULTS:The duration of antibiotic treatment after complete percutaneous drainage was 15.83 ± 6.45 d and 24.25 ± 8.18 d for the experimental and the control groups, respectively (P=0.001), being significantly shorter in the experimental group than in the control group. The recurrence rate was 0% for both groups.However, we could not obtain the follow-up data about 3 patients in the control group. CONCLUSION: CRP values can be considered as an independent factor to determine the duration of the antibiotic treatment for pyogenic liver abscess after complete percutaneous drainage.
文摘AIM: To determine the effect of procedural and clinical factors upon C reactive protein(CRP) dynamics following transcatheter aortic valve implantation(TAVI).METHODS: Two hundred and eight consecutive patients that underwent transfemoral TAVI at two hospitals(Imperial, College Healthcare NHS Trust, Hammersmith Hospital, London, United Kingdom and San Raffaele Scientific Institute, Milan, Italy) were included. Daily venous plasma CRP levels were measured for up to 7 d following the procedure(or up to discharge). Procedural factors and 30-d safety outcomes according tothe Valve Academic Research Consortium 2 definition were collected. RESULTS: Following TAVI, CRP significantly increased reaching a peak on day 3 of 87.6 ± 5.5 mg/d L, P < 0.001. Patients who developed clinical signs and symptoms of sepsis had significantly increased levels of CRP(P < 0.001). The presence of diabetes mellitus was associated with a significantly higher peak CRP level at day 3(78.4 ± 3.2 vs 92.2 ± 4.4, P < 0.001). There was no difference in peak CRP release following balloonexpandable or self-expandable TAVI implantation(94.8 ± 9.1 vs 81.9 ± 6.9, P = 0.34) or if post-dilatation was required(86.9 ± 6.3 vs 96.6 ± 5.3, P = 0.42), however, when pre-TAVI balloon aortic valvuloplasty was performed this resulted in a significant increase in the peak CRP(110.1 ± 8.9 vs 51.6 ± 3.7, P < 0.001). The development of a major vascular complication did result in a significantly increased maximal CRP release(153.7 ± 11.9 vs 83.3 ± 7.4, P = 0.02) and there was a trend toward a higher peak CRP following major/lifethreatening bleeding(113.2 ± 9.3 vs 82.7 ± 7.5, P = 0.12) although this did not reach statistical significance. CRP was not found to be a predictor of 30-d mortality on univariate analysis. CONCLUSION: Careful attention should be paid to baseline clinical characteristics and procedural factors when interpreting CRP following TAVI to determine their future management.
文摘AIM:To find a possible relationship between inflammation and CA19-9 tumor marker by analyzing data from patients with benign jaundice(BJ) and malignant jaundice(MJ).METHODS:All patients admitted for obstructive jaundice,in the period 2005-2009,were prospectively enrolled in the study,obtaining a total of 102 patients.On admission,all patients underwent complete standard blood test examinations including C-reactive protein(CRP),bilirubin,CA19-9.Patients were considered eligible for the study when they presented obstructive jaundice confirmed by instrumental examinations and increased serum bilirubin levels(total bilirubin > 2.0 mg/dL).The standard cut-off level for CA19-9 was 32 U/mL,whereas for CRP this was 1.5 mg/L.The CA19-9 level was adjusted by dividing it by the value of serum bilirubin or by the CRP value.The patients were divided into 2 groups,MJ and BJ,and after the adjustment a comparison between the 2 groups of patients was performed.Sensitivity,specificity and positive predictive values were calculated before and after the adjustment.RESULTS:Of the 102 patients,51 were affected by BJ and 51 by MJ.Pathologic CA19-9 levels were found in 71.7% of the patients.In the group of 51 BJ patients there were 29(56.9%) males and 22(43.1%) females with a median age of 66 years(range 24-96 years),whereas in the MJ group there were 24(47%) males and 27(53%) females,with a mean age of 70 years(range 30-92 years).Pathologic CA19-9 serum level was found in 82.3% of MJ.CRP levels were pathologic in 66.6% of the patients with BJ and in 49% with MJ.Bilirubin and CA19-9 average levels were significantly higher in MJ compared with BJ(P = 0.000 and P = 0.02),while the CRP level was significantly higher in BJ(P = 0.000).Considering a CA19-9 cut-off level of 32 U/mL,82.3% in the MJ group and 54.9% in the BJ group were positive for CA19-9(P = 0.002).A CA19-9 cut-off of 100 U/mL increases the difference between the two groups:35.3% in BJ and 68.6% in MJ(P = 0.0007).Adjusting the CA19-9 value by dividing it by serum bilirubin level meant that 21.5% in the BJ and 49% in the MJ group remained with a positive CA19-9 value(P = 0.003),while adjusting the CA19-9 value by dividing it by serum CRP value meant that 31.4% in the BJ group and 76.5% in the MJ group still had a positive CA19-9 value(P = 0.000004).Sensitivity,specificity,positive predictive values of CA19-9 > 32 U/mL were 82.3%,45% and 59.1%;when the cutoff was CA19-9 > 100 U/mL they were,respectively,68.6%,64.7% and 66%.When the CA19-9 value was adjusted by dividing it by the bilirubin or CRP values,these became 49%,78.4%,69.4% and 76.5%,68.6%,70.9%,respectively.CONCLUSION:The present study proposes CRP as a new and useful correction factor to improve the diag-nostic value of the CA19-9 tumor marker in patients with cholestatic jaundice.

文摘BACKGROUND: Serum high sensitive C-reactive protein (hs-CRP), which regards as a high sensitive mark of systemic inflammatory response syndrome, can provide a lot of valuable information for the treatment and prognosis of cerebrovascular disease. OBJECTIVE: To observe the differences of blood glucose, lipid, homocysteine and previous disease history among patients with acute cerebral infarction at various levels of hs-CRP and compare changes of hs-CRP of patients with various degrees of neurologic impairment. DESIGN: Contrast observation. SETTING: Department of Neurology, Shenzhou Hospital, Shenyang Medical College. PARTICIPANTS: A total of 102 patients with acute cerebral infarction were selected from Department of Neurology, Shenzhou Hospital of Shenyang Medical College from February 2005 to September 2006, including 55 males and 47 females aged from 55 to 86 years. All accepted patients met the diagnostic criteria of cerebral infarction established by the Fourth National Cerebrovascular Disease Academic Meeting and were diagnosed with CT or MRI examination. All patients provided the confirmed consent. Based on clinical criteria of neurologic impairment established by the Fourth National Cerebrovascular Disease Academic Meeting, patients were randomly divided into mild group (0–15 points, n =46), moderate group (16–30 points, n =38) and severe group (31–45 points, n =18). In addition, based on hs-CRP level within 72 hours, patients were divided into normal group (hs-CRP ≤ 3 mg/L, n =53) and increasing group (hs-CRP > 3 mg/L, n =49). METHODS: ① 2 mL venous blood was selected from hospitalized patients in the next morning to separate serum. Quantitative measurement of hs-CRP was dealt with Latex Enhnced Turbidimetric Immunoassay (LETIA). ② Fasting venous blood was colleted from hospitalized patients in the next morning to measure numeration of white blood cells, fibrinogen, blood glucose, total cholesterol (TC), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and homocysteine. ③ Measurement data were compared with t test or analysis of variance. MAIN OUTCOME MEASURES: ① Comparisons of serum biochemical indexes among patients with various levels of hs-CRP; ② comparisons of risk factors among patients with various levels of hs-CRP; ③ comparisons of levels of hs-CRP among patients with various degrees of clinical neurologic impairment. RESULTS: A total of 102 patients were involved in the final analysis. ① Plasma fibrinogen and numeration of leucocytes were more in the increasing group than those in the normal group (t =4.39, 3.54, P < 0.01); while, there were no significant differences of blood glucose, TC, TG, HDL-C, LDL-C and homocysteine between the two groups (P > 0.05). ② Percentage of patients with hypertension and diabetes mellitus (DM) was higher in the increasing group than the normal group (χ2=3.98, 4.23, P < 0.05); while, percentage of patients with smoking in the increasing group was not significantly different from that of patients in the normal group (P > 0.05). ③ Level of hs-CRP of patients with severe neurologic impairment was higher than that of patients with moderate neurologic impairment (t =2.273, P < 0.05); that of patients with moderate neurologic impairment was higher than that of patients with mild neurologic impairment (t =2.586, P < 0.05); that of patients with severe neurologic impairment was obviously higher than that of patients with mild neurologic impairment (t = 4.913, P < 0.01). CONCLUSION: ① With the increase of hs-CRP, plasma fibrinogen and numeration of leucocytes of patients with acute cerebral infarction is increased, especially, they are increased remarkably among patients who have history of diabetes mellitus and hypertension. ② Increase of level of hs-CRP can be regarded asone of marks to evaluate severity of acute stroke.
文摘BACKGROUND: Plasma inflammatory factor, such as C-reactive protein, whose content is regarded as a sensitively pathological marked protein and quantitative indexes of central nervous system injury, has been paid more and more attention in clinic. OBJECTIVE: To observe the effects and clinical significance of C-reactive protein in patients with craniocerebral injury after hyperbaric oxygenation. DESIGN: Randomized controlled study. SETTING: Departments of Neurosurgery, Laboratory and Hyperbaric Oxygen, the Second Affiliated Hospital, Medical College of Shantou University. PARTICIPANTS: A total of 60 patients with craniocerebral injury were selected from Department of Neurosurgery, the Second Affiliated Hospital, Medical College of Shantou University from October 2006 to April 2007. There were 37 males and 23 females and the mean age was 26 years. All subjects were certainly diagnosed as history of craniocerebral injury. Patients hospitalized at 24 hours after injury, Glasgow Coma Score ranged from 3 to 12 points, and all patients were certainly diagnosed with CT or MR scanning. Patients and their relatives provided confirmed consent. All the subjects were randomly divided into hyperbaric oxygenation group and control group with 30 in each group. METHODS: Patients in the control group were treated with routinely neurosurgical therapy after hospitalization; however, based the same basic treatment in the control group, patients in the hyperbaric oxygenation group received hyperbaric oxygenation by using iced-wheel four-door 2-cabin air-compression chamber (made in Yantai) from 24 hours to 10 days after operation or injury. After entering the cabin, patients who had a clear consciousness breathed the oxygen by using face mask; contrarily, patients directly breathed the oxygen. Therapeutic project: Expression was increased for about 15–20 minutes, maintained for about 70–80 minutes, and decreased for 20 minutes. Otherwise, pressure was maintained from 0.2 to 0.25 MPa. Hyperbaric oxygenation took an hour for once a day and 10 times were regarded as a course. Venous blood was collected before treatment and on the next day of the first course end. Content of C-reactive protein in plasma was measured with immune turbidimetry in hyperbaric oxygenation group; in addition, content of C-reactive protein in plasma was directly measured with the same method at the corresponding time in the control group. If the content was less or equal to 8 mg/L, it was regarded as normal value. Effects of the two groups were evaluated based on Glasgow Coma Score before and after treatment. MAIN OUTCOME MEASURES: Content of plasma C-reactive protein and Glasgow Coma Score in the two groups before and after treatment. RESULTS: All 60 patients were involved in the final analysis. ① Content of plasma C-reactive protein: The two contents were obviously higher than normal value after craniocerebral injury. There was no significant difference in the two groups before treatment (P > 0.05), but both contents were decreased after treatment, and there was significant difference between HBOT group and control group after treatment (t =4.756, P < 0.01). In addition, there was significant difference in hyperbaric oxygen therapy group before and after treatment (t =5.236, P < 0.01). ② Glasgow Coma Score: There was no significant difference in the two groups before treatment (P > 0.05), but scores were increased in both groups after treatment (t =9.92, 2.51, P < 0.01, 0.05); on the other hand, therefore, there was significant difference between the two groupsafter treatment (t =9.21, P < 0.01). CONCLUSION: Hyperbaric oxygenation can remarkably decrease content of plasma C-reactive protein in patients with craniocerebral injury at the phase of stress.

文摘Objective We aimed to evaluate the combined effects of a high body shape index(ABSI) and a high serum C-reactive protein(CRP) level on the incidence of ischemic stroke in a Mongolian population in China. Methods A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios(HRs) and 95% confidence intervals(CIs) for ischemic stroke among all groups. Results The multivariate adjusted HRs(95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46(0.89-2.39) and 1.63(0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs(95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04(0.46-2.35), 1.06(0.58-1.95) and 2.52(1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant. Conclusion We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.
