Methods: Inadrenalectomised (ADX) and ADX + hydrocortisone (1, 2, or 4 mg) treated rats, the prostatic histology and thecholesterol, protein, zinc, and copper levels and the enzymic profile (acid phosphatase, alkaline phosphatase, aryl sul-phatase, lactic dehydrogenase, and leucine aminopeptidase) in the prostatic tissue were determined; the serum hormon-al profile (testosterone, FSH and LH) was also assayed. Results; Adrenalectomy caused a progressive degenerationin prostatic structure that was not reversed by hydrocortisone treatment. The serum testosterone were significantly lowerin ADX than in sham operated rats and lower in ADX + hydrocortisone than in ADX-C rats (P < 0.01). The serumFSH and LH were below the detection limit of 1 mIU/mL. The enzymatic activity was higher in ADX than in sham op-erated rats and higher in ADX + hydrocortisone than in ADX-C rats (P<0.05-0.01). The prostatic zinc levels weresignificantly higher in sham operated than in ADX, and higher in ADX-C than in ADX + hydrocortisone rats (P < 0.05-0.01). The prostatic copper level was significantly lower in sham operated than in ADX, and lower in ADX-C thanin the ADX + hydrocortisone rats (P <0.01). Conclusion; In rats, adrenalectomy leads to pathological and func-tional changes of the prostate. Hydrocortisone treatment at the doses employed did not reverse these changes.

Demographic data, comorbidities, medical management details, adverse effects related to corticosteroids, and outcomes were collected after the critical care physician indicated initiation of hydrocortisone. Univariate comparison between continuous and bolus administration of hydrocortisone was performed, including multivariate analysis, as well as Kaplan-Meier analysis to compare the proportion of shock reversal at 7 d after presentation. Receiver operating characteristic(ROC) curves determined the best cut-off criteria for initiation of hydrocortisone associated with the highest probability of shock reversal. We addressed the effects of the taper strategy for discontinuation of hydrocortisone, noting risk of shock relapse and adverse effects.RESULTS All-cause 30-d mortality was 42%. Hydrocortisone was administered as a continuous infusion in 54.2% of patients; time to reversal of shock was 49 h longer in patients who were given a bolus administration [59 h(range, 47.5-90.5) vs 108 h(range, 63.2-189); P = 0.001]. The maximal dose of norepinephrine after initiation of hydrocortisone was lower in patients on continuous infusion [0.19 μg/kg per minute(range, 0.11-0.28 μg)] compared with patients who were given bolus [0.34 μg/kg per minute(range, 0.16-0.49); P = 0.004]. Kaplan-Meier analysis revealed a higher proportion of shock reversal at 7 d in patients with continuous infusion compared to those given bolus(83% vs 63%; P = 0.004). There was a good correlation between time to initiation of hydrocortisone and time to reversal of shock(r = 0.80; P < 0.0001); ROC curve analysis revealed that the best criteria for prediction of shock reversal was a time to initiation of hydrocortisone of ≤ 13 h after administration of norepinephrine, with an area under the curve of 0.81(P < 0.001). The maximal dose of norepinephrine at initiation of hydrocortisone with the highest association with shock reversal was ≤ 0.28 μg/kg per minute, with an area under the curve of 0.75(P = 0.0002). On a logistic regression model, hydrocortisone taper was not associated with a lower risk of shock relapse(RR = 1.29; P = 0.17) but was related to a higher probability of hyperglycemia [odds ratio(OR), 5.3; P = 0.04] and hypokalemia(OR = 10.6; P = 0.01). CONCLUSION Continuous infusion of hydrocortisone could hasten the resolution of septic shock compared to bolus administration. Earlier initiation corresponds with a higher probability of shock reversal. Tapering strategy is unnecessary.展开更多

Methods: Using consecutive intramuscular injection of hydrocortisone to build Shen-yang deficiency model rats, and detect their hemorheological and biochemical parameters. Results: Comparison between the model group and control group showed that the in vitro thrombus significantly lengthened in the model group (P<0.05), the dry weight increased (P<0.01), hematocrit and whole blood viscosity under high sheared change lowered (P<0.05), blood glucose elevated (P<0.01), and RBC infiltration index, aggregation index increased (P close to 0.05). Conclusion: Under the condition of Shen-yang deficiency, although blood does not show such properties of blood stasis as being 'viscous, concentrated, coagulated and aggregated', partial change of hemorheology occurs, and it is liable to form thrombus, which proves that the Shen deficiency status is accompanied with the tendency of blood stasis.展开更多

There are several pharmaceutical dosage forms available using different corticosteroids. Topical steroids of varying potencies are available in creams, ointments, solutions and other vehicles. Chemical instability and drug degradation are the key quality concerns for these topical dosage forms. Nature of the dosage forms, excipient quality, product composition, and process optimization are some of the common factors which affect the stability of corticosteroids. This article describes drug degradation behavior of three different corticosteroids in different topical dosage forms. Drug degradation patterns of Hydrocortisone, Clobetasol propionate and Desonide formulations observed in stability studies of respective finished drug products under ICH recommended storage conditions were investigated. HPLC, UPLC-MS/MS methods were developed for the separation and characterization of impurities. The structural elucidation of the unknown impurities observed for these steroids and mechanistic consideration of potential degradation pathways has been discussed. Detailed discussion on the analytical methodologies is included as well.展开更多

One of the best procedures for inhibiting the accumulation of vascular calcification is to obstruct the differentiation of mesenchymal stem cells (MSCs) and/or vascular endothelial cells (VECs) in the vascular to osteoblasts. In this study, we evaluated the biochemical and genetic characteristics of the process of differentiation of MSCs and VECs to osteoblasts. C3H10T1/2 MSCs, TKD2 VECs and MC3T3-E1 preosteoblasts (POBs) were cultured in medium containing both hydrocortisone and glycerophosphate. These compounds showed strong effects promoting the differentiation of VECs as well as POBs, although the effect was weak in the MSCs. Moreover, C3H10T1/2 MSCs and TKD2 VECs were cultured in medium containing 10 mM retinol, after which the alkali phosphatase (ALP) activity of the MSCs and production of calcified nodules of TKD2 were significantly increased, whereas the marker genes for the osteoblasts were not. These results suggest that retinol does not have an effect in inducing the differentiation of VECs to osteoblasts, but rather exhibits a strong promoting effect on differentiation.展开更多

Topical steroids and oral antihistamines are the conventional treatment. However, the side effects from prolonged use of topical steroids are the limitation of the treatment. Recently, herbal extracts are emerging interest for an alternative anti-inflammatory dermatoses therapy. Objective: To assess the effectiveness of herbal extracted gel containing, Perilla frutescens, Portulaca oleracea, Ipomoea pescaprae, Aloe vera, Centella asiatica and Broussonetia papyrifera in comparing with 1% hydrocortisone (HC) gel. Material and Methods: An experimental study was conducted on 50 mosquito bite hypersensitive volunteers (15 - 19 years old) with double-blinded split randomized control method. After the volunteers were exposed for one bite on their arms by a non-infectious mosquito, Aedes albopictus, the drugs were applied twice daily. The diameter of lesion, pruritus analog score, erythema and melanin index were measured at 2, 6, 24 hours and 2, 3, 4 weeks. The volunteers “self-satisfaction” and side effects were recorded. Results: The mean age was 17.42 ± 1.14 years old. The diameter of lesion, pruritus analog score, erythema and melanin index were decreased on both sides at each visit with significant difference (p < 0.05). There was no significant difference between two agents of all parameters and the satisfaction of the volunteers (p > 0.05). The post-inflammatory hyperpigmentation rate of 1% HC and herbal gel was 64% and 54% respectively without significant difference (p = 0.267). Conclusion: The herbal gel was as effective as 1% HC for the treatment of acute and late reaction of mosquito bite reaction in adolescent. It may be used as the alternative treatment for mosquito bite reaction.展开更多

We investigated the effects of prior treatment with hydrocortisone on the production of ICAM-1 and its counterreceptors （LFA-1 and Mac-1） in AP of rats to clarify the effect of hydrocortisone on induced acute pancreatitis.Methods Acute pancreatitis was induced by infusion of 5% chenodeoxycholic acid into the pancreatic duct, followed by ligation of pancreatic duct. Before induction of acute pancreatitis, rats were treated with hydrocortisone （n=20） or 0.9% saline （n=-20）. Blood and specimens from pancreas and lung were obtained from 5 rats from each treatment euthanized at 1 hour or 3 hours, 6 hours, 12 hours. Expression of ICAM-1 was assessed by immunohistochemistry and Western blot analysis of pancreas and lungs. The expression of LFA-1 and Mac-1 on neutrophils was detected by flow cytometer. The therapeutic effect of hydrocortisone was assessed from injuries to pancreas and lung.Results ICAM-1 expression in the pancreas of hydrocortisone group was significantly less than in control group at 3 hours and 6 hours. In the lungs of hydrocortisone group, ICAM-1 expression was significantly less than in control group at 3 hours, 6 hours and 12 hours. The expression of LFA-1 and Mac-1 on neutrophils in blood increased significantly in control group over hydrocortisone group. Increased expression of ICAM-1, LFA-1 and Mac-1 preceded leukocyte infiltration. Compared to untreated animals with acute pancreatitis, rats pretreated with hydrocortisone had significantly reduced histological lung injury and output of ascitic fluid.Conclusions Prior treatment with hydrocortisone before the induction of acute pancreatitis ameliorates pulmonary injury and the output of ascitic fluid and reduces the expression of ICAM-1 and its counterreceptors （LFA-1, Mac-1） in acute pancreatitis.展开更多

Hydrocortisone antigen was labeled with the synthesized core/shell CdSe/CdS quantum dots （QDs） to form the antigen-QDs conjugate. Meanwhile, hydrocortisone antibody was incubated with MCFN and the immobilized antibody was obtained. The immobilized antibody was then mixed sequentially with hydrocortisone and a slightly excess amount of the QDs-labeled hydrocortisone antigen, allowing their competition for binding with the antibody immobilized on MCFN. The bound hydrocortisone and the antigen-QDs conjugates on MCFN were removed subsequently after the mixture was applied to a magnetic force. The analyte concentration was obtained by measuring the fluorescence intensity of the unbound hydrocortisone antigen-QDs conjugates. The proposed method was characterized by simplicity, rapidity, and high sensitivity with a wide linear working range of 0.5 to 15000 pg·mL^-1 and a low detection limit of 0.5 pg.mL^- 1. The proposed method was successfully applied to the determination of hydrocortisone in cosmetics with satisfactory results.展开更多

The stage of high concentration of steroid hormone leading to a wide range of symptoms is associated to the yang.deficient state, which is the part of yin-yang imbalance involved in processes of many diseases in traditional Chinese medicine. Here we intend to investigate the profile of Th1/Th2- related cytokine transcriptions under yang-deficient conditions in a yang-deficient animal model by intramuscular injection of hydrocortisone （a kind of steroid hormone）. The yang.deficient symptoms were estimated by detecting activity, appetite, body weight and so on. T cell proliferation and cytokine transcriptions were analyzed. The results showed that yang-deficient mice were established successfully since typical yang.deficient symptoms were observed in this model with decreased activities, appetite, body weight and temperature. More interestingly, the transcriptions of IFN-γ, IL-2, IL-4 and IL-10 in this model were markedly suppressed and the proliferation of lymphocytes significantly decreased as well. The results suggested thatyang-deficient symptoms were related to the steroid-induced reduction of cytokine transcription and impairment of lymphocyte proliferation. Therefore, novel strategies through regulating cytokine production might be considered as potent approach to patients with yang.deficiency symptoms.展开更多

Methods： Thirty-six male SD rats were randomly allocated into three groups. The rats in the control group （n=6） underwent no treatment. The rats in the model group （n=15） were induced by hydrocortisone and not treated. The rats in the electroacupuncture group （n=15） were induced by hydrocortisone and treated with electroacupuncture. The luteinizing hormone （LH） and the testosterone （T） were tested with radioimmunoassay, while the hematoxylin-eosin （HE） staining was used for histological observation. Results： Compared with the pre-modeling, the serum T decreased significantly after the modeling （P0.05）, and the LH increased without significant difference. The delamination of spermatids reduced dramatically. After the treatments, the serum LH of the rats in the electroacupuncture group were significantly higher than the rats in the model group （P0.05） but the serum T increased without significant difference. The delamination of spermatids increased notablely （P0.05）. Conclusion： Electroacupuncture may regulate the reproductive function of the rats by improving the level of LH and T concentration.展开更多

Objectives: To assess the efficacy and safety of adjunctive low dose hydrocortisone infusion treatment in Egyptian ICU patients with CAP. Methods: Hospitalized patients, clinically and radiologically diagnosed with CAP, were randomized to receive hydrocortisone 12.5 mg/h IV infusion for 7 days or placebo, along with antibiotics. The end-points of the study were improvement in PaO2:FIO2 (PaO2:FIO2 > 300 or ≥100 increase from study entry) and SOFA score by study day 8 and the development of delayed septic shock. Results: 80 patients were recruited, 40 of them received hydrocortisone and the remaining 40 received placebo. By study day 8, hydrocortisone treated patients showed a significant improvement in PaO2:FIO2 and chest radiograph score, and a significant reduction in C-reactive protein (CRP) levels, Sepsis-related Organ Failure Assessment (SOFA) score, and delayed septic shock compared to the control group. Hydrocortisone treatment was associated with a significant reduction in the duration of MV. However, hydrocortisone infusion did not show significant difference in the ICU mortality. Conclusions: adjunctive 7-day course of low dose hydrocortisone IV in patients with CAP hastens recovery of pneumonia and prevents the development of sepsis related complications with a significant reduction in duration of the mechanical ventilation.展开更多

They were all accorded with the diagnostic standards for Rome Ⅱ functional dyspepsia functional dyspepsia. As the patients＇ will, they were divided into treatment group （n =30, 12 males and 18 females） and control group （n =15, 6 males and 9 females）, and there were no significant differences in the data between the two groups （P 〉 0.05）. The programs were discussed and agreed by the committee of medical ethics of the First Affiliated Hospital of Zhengzhou University. Informed contents were obtained from all the patients.METHODS： In the treatment group, the patients were treated with venlafaxine sustained release capsule （75 mg per day）, and those with sleep disorder were added by benzodiazepines （alprazolam）. In the control group, the patients were given routine treatments of antacid, prokinetics, etc. Before and after 8-week treatment, the following examinations were performed： ① The gastrointestinal symptoms were assessed according to the symptoms; ② The severity of depression was evaluated with Hamilton depression scale （HAMD）; ③The relaxation of proximal stomach was observed using water load test; ④ The serum level of cortisol was detected.MAIN OUTCOME MEASURES： ① Symptom score; ② HAMD score; ③ Water load amount; ④Serum level of cortisol.RESULTS： All the 45 patients were involved in the analysis of results. ① Symptom score： The scores of gastrointestinal symptoms were decreased as compared with those before treatment in both the treatment group and control group （P 〈 0.05）. ② HAMD scores： The scores of HAMD were decreased as compared with those before treatment in both the treatment group and control group （P 〈 0.05）. ③ Water load amount：The total effective rate was significantly higher in the treatment group than the control group （P 〈 0.05）. ④The serum levels of cortisol after treatment were significantly lower than those before treatment in the patients with severe gastrointestinal symptoms in the treatment group and control group （P 〈 0.05）.CONCLUSION： Antidepressants can normalize the cortisol level of patients with functional dyspepsia, and then decrease gastric sensitivity and ameliorates the receptive relaxation of proximal stomach, also increase the water load amount correspondingly, and finally control the gastrointestinal symptoms of functional dyspepsia.展开更多
文摘Aim: To study the effects of adrenalectomy and hydrocortisone on the ventral prostate of SD rats. Methods: Inadrenalectomised (ADX) and ADX + hydrocortisone (1, 2, or 4 mg) treated rats, the prostatic histology and thecholesterol, protein, zinc, and copper levels and the enzymic profile (acid phosphatase, alkaline phosphatase, aryl sul-phatase, lactic dehydrogenase, and leucine aminopeptidase) in the prostatic tissue were determined; the serum hormon-al profile (testosterone, FSH and LH) was also assayed. Results; Adrenalectomy caused a progressive degenerationin prostatic structure that was not reversed by hydrocortisone treatment. The serum testosterone were significantly lowerin ADX than in sham operated rats and lower in ADX + hydrocortisone than in ADX-C rats (P < 0.01). The serumFSH and LH were below the detection limit of 1 mIU/mL. The enzymatic activity was higher in ADX than in sham op-erated rats and higher in ADX + hydrocortisone than in ADX-C rats (P<0.05-0.01). The prostatic zinc levels weresignificantly higher in sham operated than in ADX, and higher in ADX-C than in ADX + hydrocortisone rats (P < 0.05-0.01). The prostatic copper level was significantly lower in sham operated than in ADX, and lower in ADX-C thanin the ADX + hydrocortisone rats (P <0.01). Conclusion; In rats, adrenalectomy leads to pathological and func-tional changes of the prostate. Hydrocortisone treatment at the doses employed did not reverse these changes.

文摘AIM To characterize the prescribing patterns for hydrocortisone for patients with septic shock and perform an exploratory analysis in order to identify the variables associated with better outcomes.METHODS This prospective cohort study included 59 patients with septic shock who received stress-dose hydrocortisone.It was performed at 2 critical care units in academic hospitals from June 1st, 2015, to July 31 st, 2016. Demographic data, comorbidities, medical management details, adverse effects related to corticosteroids, and outcomes were collected after the critical care physician indicated initiation of hydrocortisone. Univariate comparison between continuous and bolus administration of hydrocortisone was performed, including multivariate analysis, as well as Kaplan-Meier analysis to compare the proportion of shock reversal at 7 d after presentation. Receiver operating characteristic(ROC) curves determined the best cut-off criteria for initiation of hydrocortisone associated with the highest probability of shock reversal. We addressed the effects of the taper strategy for discontinuation of hydrocortisone, noting risk of shock relapse and adverse effects.RESULTS All-cause 30-d mortality was 42%. Hydrocortisone was administered as a continuous infusion in 54.2% of patients; time to reversal of shock was 49 h longer in patients who were given a bolus administration [59 h(range, 47.5-90.5) vs 108 h(range, 63.2-189); P = 0.001]. The maximal dose of norepinephrine after initiation of hydrocortisone was lower in patients on continuous infusion [0.19 μg/kg per minute(range, 0.11-0.28 μg)] compared with patients who were given bolus [0.34 μg/kg per minute(range, 0.16-0.49); P = 0.004]. Kaplan-Meier analysis revealed a higher proportion of shock reversal at 7 d in patients with continuous infusion compared to those given bolus(83% vs 63%; P = 0.004). There was a good correlation between time to initiation of hydrocortisone and time to reversal of shock(r = 0.80; P < 0.0001); ROC curve analysis revealed that the best criteria for prediction of shock reversal was a time to initiation of hydrocortisone of ≤ 13 h after administration of norepinephrine, with an area under the curve of 0.81(P < 0.001). The maximal dose of norepinephrine at initiation of hydrocortisone with the highest association with shock reversal was ≤ 0.28 μg/kg per minute, with an area under the curve of 0.75(P = 0.0002). On a logistic regression model, hydrocortisone taper was not associated with a lower risk of shock relapse(RR = 1.29; P = 0.17) but was related to a higher probability of hyperglycemia [odds ratio(OR), 5.3; P = 0.04] and hypokalemia(OR = 10.6; P = 0.01). CONCLUSION Continuous infusion of hydrocortisone could hasten the resolution of septic shock compared to bolus administration. Earlier initiation corresponds with a higher probability of shock reversal. Tapering strategy is unnecessary.
文摘Objective:To explore the relationship between Shen deficiency and blood stasis. Methods: Using consecutive intramuscular injection of hydrocortisone to build Shen-yang deficiency model rats, and detect their hemorheological and biochemical parameters. Results: Comparison between the model group and control group showed that the in vitro thrombus significantly lengthened in the model group (P<0.05), the dry weight increased (P<0.01), hematocrit and whole blood viscosity under high sheared change lowered (P<0.05), blood glucose elevated (P<0.01), and RBC infiltration index, aggregation index increased (P close to 0.05). Conclusion: Under the condition of Shen-yang deficiency, although blood does not show such properties of blood stasis as being 'viscous, concentrated, coagulated and aggregated', partial change of hemorheology occurs, and it is liable to form thrombus, which proves that the Shen deficiency status is accompanied with the tendency of blood stasis.
文摘Corticosteroids are the most widely used class of anti-inflammatory medications in the pharmaceutical industry. There are several pharmaceutical dosage forms available using different corticosteroids. Topical steroids of varying potencies are available in creams, ointments, solutions and other vehicles. Chemical instability and drug degradation are the key quality concerns for these topical dosage forms. Nature of the dosage forms, excipient quality, product composition, and process optimization are some of the common factors which affect the stability of corticosteroids. This article describes drug degradation behavior of three different corticosteroids in different topical dosage forms. Drug degradation patterns of Hydrocortisone, Clobetasol propionate and Desonide formulations observed in stability studies of respective finished drug products under ICH recommended storage conditions were investigated. HPLC, UPLC-MS/MS methods were developed for the separation and characterization of impurities. The structural elucidation of the unknown impurities observed for these steroids and mechanistic consideration of potential degradation pathways has been discussed. Detailed discussion on the analytical methodologies is included as well.
文摘Vascular calcification, which causes occlusion and rupture of the vascular, is often observed in patients in the advanced stages of arteriosclerosis. One of the best procedures for inhibiting the accumulation of vascular calcification is to obstruct the differentiation of mesenchymal stem cells (MSCs) and/or vascular endothelial cells (VECs) in the vascular to osteoblasts. In this study, we evaluated the biochemical and genetic characteristics of the process of differentiation of MSCs and VECs to osteoblasts. C3H10T1/2 MSCs, TKD2 VECs and MC3T3-E1 preosteoblasts (POBs) were cultured in medium containing both hydrocortisone and glycerophosphate. These compounds showed strong effects promoting the differentiation of VECs as well as POBs, although the effect was weak in the MSCs. Moreover, C3H10T1/2 MSCs and TKD2 VECs were cultured in medium containing 10 mM retinol, after which the alkali phosphatase (ALP) activity of the MSCs and production of calcified nodules of TKD2 were significantly increased, whereas the marker genes for the osteoblasts were not. These results suggest that retinol does not have an effect in inducing the differentiation of VECs to osteoblasts, but rather exhibits a strong promoting effect on differentiation.
文摘Background: Mosquito bite reaction is a common skin disease. Topical steroids and oral antihistamines are the conventional treatment. However, the side effects from prolonged use of topical steroids are the limitation of the treatment. Recently, herbal extracts are emerging interest for an alternative anti-inflammatory dermatoses therapy. Objective: To assess the effectiveness of herbal extracted gel containing, Perilla frutescens, Portulaca oleracea, Ipomoea pescaprae, Aloe vera, Centella asiatica and Broussonetia papyrifera in comparing with 1% hydrocortisone (HC) gel. Material and Methods: An experimental study was conducted on 50 mosquito bite hypersensitive volunteers (15 - 19 years old) with double-blinded split randomized control method. After the volunteers were exposed for one bite on their arms by a non-infectious mosquito, Aedes albopictus, the drugs were applied twice daily. The diameter of lesion, pruritus analog score, erythema and melanin index were measured at 2, 6, 24 hours and 2, 3, 4 weeks. The volunteers “self-satisfaction” and side effects were recorded. Results: The mean age was 17.42 ± 1.14 years old. The diameter of lesion, pruritus analog score, erythema and melanin index were decreased on both sides at each visit with significant difference (p < 0.05). There was no significant difference between two agents of all parameters and the satisfaction of the volunteers (p > 0.05). The post-inflammatory hyperpigmentation rate of 1% HC and herbal gel was 64% and 54% respectively without significant difference (p = 0.267). Conclusion: The herbal gel was as effective as 1% HC for the treatment of acute and late reaction of mosquito bite reaction in adolescent. It may be used as the alternative treatment for mosquito bite reaction.

文摘Background This study aimed to conduct a systematic review and meta-analysis of the efficacy of hydrocortisone,vitamin C,and thiamine(HVT)in patients with sepsis or septic shock.Methods A literature search was performed in PubMed,Embase,Cochrane Library,and Web of Science from their inception to April 2021.Search terms included hydrocortisone,thiamine,vitamin C,sepsis,and septic shock.Only randomized controlled trials on HVT in treating sepsis and septic shock were analyzed.Risk ratio(RR)was generated using Review Manager 5.3 to evaluate binary variants,whereas mean±standard deviation(MD)was generated to assess continuous variants.Results A total of 7 randomized controlled trials,with 1233 patients,were included in this meta-analysis.There was no significant difference in long-term mortality(35.3%vs 33.2%;RR:1.07;95%confidence interval[95%CI]:0.90-1.27;P=0.45;I^(2)=0%),intensive care unit(ICU)mortality(17.4%vs 17.5%;RR:0.99;95%CI:0.75-1.30;P=0.95;I^(2)=0%),in-hospital mortality(27.4%vs 25.8%;RR:1.06;95%CI:0.84-1.34;P=0.63;I^(2)=0%),and acute kidney injury morbidity(RR:1.04;95%CI:0.91-1.18;P=0.60;I^(2)=0%)between HVT and control groups.For continuous variables,there was no significant effect of HVT therapy on delta Sequential Organ Failure Assessment(△SOFA)score(MD:−0.44;95%CI:−1.00 to 0.12;P=0.12;I^(2)=49%),length of ICU stay(MD:0.43;95%CI:−0.27 to 1.14;P=0.23;I^(2)=0%),and length of hospital stay(MD:0.80;95%CI:−0.38 to 1.97;P=0.18;I^(2)=0%).Only vasopressor duration was significantly reduced in the HVT group(MD:−17.75;95%CI:−25.56 to−9.94;P<0.00001;I^(2)=38%).Vasopressor duration refers to the time to shock reversal.Alternatively,it is the amount of time(in hours)required for patients to withdraw all vasoactive medication support.Neither HVT nor control△SOFA reached statistical significance.Conclusion Hydrocortisone,vitamin C,and thiamine use was not associated with improved mortality,lower acute kidney injury incidence,lower△SOFA,and shorter ICU and in-hospital stays among patients with sepsis and septic shock.However,the use of vasopressors decreased significantly.Further direct head-to-head studies are needed.

文摘Background Little is known of the effects of hydrocortisone on cell adhesion molecules such as intercellular adhesion molecule-1 （ICAM-1） and its counterreceptors （LFA-1, Mac-1） in acute pancreatitis （AP）. We investigated the effects of prior treatment with hydrocortisone on the production of ICAM-1 and its counterreceptors （LFA-1 and Mac-1） in AP of rats to clarify the effect of hydrocortisone on induced acute pancreatitis.Methods Acute pancreatitis was induced by infusion of 5% chenodeoxycholic acid into the pancreatic duct, followed by ligation of pancreatic duct. Before induction of acute pancreatitis, rats were treated with hydrocortisone （n=20） or 0.9% saline （n=-20）. Blood and specimens from pancreas and lung were obtained from 5 rats from each treatment euthanized at 1 hour or 3 hours, 6 hours, 12 hours. Expression of ICAM-1 was assessed by immunohistochemistry and Western blot analysis of pancreas and lungs. The expression of LFA-1 and Mac-1 on neutrophils was detected by flow cytometer. The therapeutic effect of hydrocortisone was assessed from injuries to pancreas and lung.Results ICAM-1 expression in the pancreas of hydrocortisone group was significantly less than in control group at 3 hours and 6 hours. In the lungs of hydrocortisone group, ICAM-1 expression was significantly less than in control group at 3 hours, 6 hours and 12 hours. The expression of LFA-1 and Mac-1 on neutrophils in blood increased significantly in control group over hydrocortisone group. Increased expression of ICAM-1, LFA-1 and Mac-1 preceded leukocyte infiltration. Compared to untreated animals with acute pancreatitis, rats pretreated with hydrocortisone had significantly reduced histological lung injury and output of ascitic fluid.Conclusions Prior treatment with hydrocortisone before the induction of acute pancreatitis ameliorates pulmonary injury and the output of ascitic fluid and reduces the expression of ICAM-1 and its counterreceptors （LFA-1, Mac-1） in acute pancreatitis.

文摘This work demonstrated the feasibility of detecting hydrocortisone in cosmetics using a novel CdSe/CdS quan- tum dots-based competitive fluoroimmunoassay with magnetic core/shell Fe3Oa/Au nanoparticles （MCFN） as solid carriers. Hydrocortisone antigen was labeled with the synthesized core/shell CdSe/CdS quantum dots （QDs） to form the antigen-QDs conjugate. Meanwhile, hydrocortisone antibody was incubated with MCFN and the immobilized antibody was obtained. The immobilized antibody was then mixed sequentially with hydrocortisone and a slightly excess amount of the QDs-labeled hydrocortisone antigen, allowing their competition for binding with the antibody immobilized on MCFN. The bound hydrocortisone and the antigen-QDs conjugates on MCFN were removed subsequently after the mixture was applied to a magnetic force. The analyte concentration was obtained by measuring the fluorescence intensity of the unbound hydrocortisone antigen-QDs conjugates. The proposed method was characterized by simplicity, rapidity, and high sensitivity with a wide linear working range of 0.5 to 15000 pg·mL^-1 and a low detection limit of 0.5 pg.mL^- 1. The proposed method was successfully applied to the determination of hydrocortisone in cosmetics with satisfactory results.

文摘Steroid hormone serving as an immunosuppressor often induces immunotoxicity when administered in highest dosage or accumulated in long-term usage. The stage of high concentration of steroid hormone leading to a wide range of symptoms is associated to the yang.deficient state, which is the part of yin-yang imbalance involved in processes of many diseases in traditional Chinese medicine. Here we intend to investigate the profile of Th1/Th2- related cytokine transcriptions under yang-deficient conditions in a yang-deficient animal model by intramuscular injection of hydrocortisone （a kind of steroid hormone）. The yang.deficient symptoms were estimated by detecting activity, appetite, body weight and so on. T cell proliferation and cytokine transcriptions were analyzed. The results showed that yang-deficient mice were established successfully since typical yang.deficient symptoms were observed in this model with decreased activities, appetite, body weight and temperature. More interestingly, the transcriptions of IFN-γ, IL-2, IL-4 and IL-10 in this model were markedly suppressed and the proliferation of lymphocytes significantly decreased as well. The results suggested thatyang-deficient symptoms were related to the steroid-induced reduction of cytokine transcription and impairment of lymphocyte proliferation. Therefore, novel strategies through regulating cytokine production might be considered as potent approach to patients with yang.deficiency symptoms.
文摘Objective： To observe the impact of electroacupuncture on the reproductive function of hydrocortisone acetate modeling rats. Methods： Thirty-six male SD rats were randomly allocated into three groups. The rats in the control group （n=6） underwent no treatment. The rats in the model group （n=15） were induced by hydrocortisone and not treated. The rats in the electroacupuncture group （n=15） were induced by hydrocortisone and treated with electroacupuncture. The luteinizing hormone （LH） and the testosterone （T） were tested with radioimmunoassay, while the hematoxylin-eosin （HE） staining was used for histological observation. Results： Compared with the pre-modeling, the serum T decreased significantly after the modeling （P0.05）, and the LH increased without significant difference. The delamination of spermatids reduced dramatically. After the treatments, the serum LH of the rats in the electroacupuncture group were significantly higher than the rats in the model group （P0.05） but the serum T increased without significant difference. The delamination of spermatids increased notablely （P0.05）. Conclusion： Electroacupuncture may regulate the reproductive function of the rats by improving the level of LH and T concentration.

文摘Background: Pneumonia is the most common cause of community-acquired infection requiring ICU admission. 60-87% of patients with severe community acquired pneumonia (CAP) admitted to the ICU develops respiratory failure and require mechanical ventilation (MV). Objectives: To assess the efficacy and safety of adjunctive low dose hydrocortisone infusion treatment in Egyptian ICU patients with CAP. Methods: Hospitalized patients, clinically and radiologically diagnosed with CAP, were randomized to receive hydrocortisone 12.5 mg/h IV infusion for 7 days or placebo, along with antibiotics. The end-points of the study were improvement in PaO2:FIO2 (PaO2:FIO2 > 300 or ≥100 increase from study entry) and SOFA score by study day 8 and the development of delayed septic shock. Results: 80 patients were recruited, 40 of them received hydrocortisone and the remaining 40 received placebo. By study day 8, hydrocortisone treated patients showed a significant improvement in PaO2:FIO2 and chest radiograph score, and a significant reduction in C-reactive protein (CRP) levels, Sepsis-related Organ Failure Assessment (SOFA) score, and delayed septic shock compared to the control group. Hydrocortisone treatment was associated with a significant reduction in the duration of MV. However, hydrocortisone infusion did not show significant difference in the ICU mortality. Conclusions: adjunctive 7-day course of low dose hydrocortisone IV in patients with CAP hastens recovery of pneumonia and prevents the development of sepsis related complications with a significant reduction in duration of the mechanical ventilation.

文摘A new flow-injection procedure has been developed for the determination of penicillamine based on the enhancement of the chemiluminescence(CL) reaction of the penicillamine-cerium(Ⅳ)-hydrocortisone system. The method was simple, selective and sensitive with a detection limit of 6.2×10-5 mol·L-1(S/N=3). It was applicable to the determination of penicillamine in the concentration range of 2×10-6～5×10-4 mol·L-1. The method was successfully applied to the determination of penicillamine in tablets. The relative standard deviation (RSD) was 1.42% (n=7) and the recovery was 97%～103% (n=4).
文摘AIM:To evaluate the role of medical treatment in the management of inflammatory punctum stenosis guided by spectral domain anterior segment optical coherence tomography(OCT).METHODS:This prospective study included 60 patients complaining of epiphora due to inflammatory punctual stenosis.They were divided into two groups:Group A(30 patients)treated with a combination of preservative free hydrocortisone sodium phosphate 3.35 mg/m L eye drops,and preservative free artificial tears based on sodium hyaluronate,polyethylene and propylene Glycol;Group B(30 patients)treated with the same preservative free artificial tears only.Thirty normal subjects were included for comparison of pre-treatment anatomical parameters.Before starting treatment,all patients underwent anterior segment assessment including slit lamp examination,measurement of intraocular pressure(IOP),fluorescein dye disappearance test,and measurement of the outer punctum diameter(OPD)by Spectral domain anterior segment OCT.All assessments were repeated at each follow up done at 1 and 3 mo later,together with subjective evaluation of patient’s satisfaction of the treatment outcome by simple rating questionnaire.RESULTS:Punctual diameter increased significantly with treatment in both groups(P<0.0001);although the widening was more in Group A as compared to group B(16.2%vs 8%of the original punctual size,mean difference of 28.933μm,P=0.0076).Subjective satisfaction with treatment outcome was also better in group A(70%vs 40%,Chi-square P=0.0397).CONCLUSION:A combination of preservative free steroid eye drops and artificial tears causes significant widening of inflammed stenotic punctae and improvement of the associated epiphora.
文摘The effect of glucocorticoids on the down-regulation of glucocorticoidreceptor (GR) mRNA was studied in intact rats.GR mRNA was characterized byNorthern blot hybridization and quantitated by dot blot hybridization using a hu-man GR cDNA fragment as a probe.Administration of hydrocortisone (F) inpolyvinyl alcohol (PVA) resulted in a rapid increase in plasma glucocorticoidswhich maintained at stress levels (20 to 40μg/dl) for about 3 d.HepaticGR mRNA decreased significantly to 73.5±6.3% of control values 6h followingF treatment,after which the decline of GR mRNA was gradual,reaching a mini-mum of 44.0±5.0% of control levels 3d after the treatment.The effect of F onthe down-regulation of hepatic GR mRNA lasted up to 11 d.In contrast,F treat-ment had no effect on GR mRNA in rat brain.These results are consistent withthe changes in GR in rats as reported previously,except that even though thehepatic cytosol GR decreased markedly,no significant changes in hepatic GRmRNA were found 1h after F treatment,strongly suggesting that thedown-regulation of GR by its ligands in vivo occurs at both transcriptional andposttranscriptional levels and is of tissue-specific fashion.
