It can occur in high-risk infants such as preterm infants, infants on long-term diuretics or corticosteroids, and those with neuromuscular disorders. Complications such as rickets, pathological fractures, impaired respiratory function and poor growth in childhood can develop and may be the first clinical evidence of the condition. It is important for neonatologists managing such high-risk patients to regularly monitor biochemical markers for evidence of abnormal bone turnover and inadequate mineral intake in order to detect the early phases of impaired bone mineralization. Dual-energy X-ray absorptiometry has become an increasingly used research tool for assessing bone mineral density in children and neonates, but more studies are still needed before it can be used as a useful clinical tool. Prevention and early detection of osteopenia are key to the successful management of this condition and oral phosphate supplements should be started as soon as is feasible.展开更多

Methods: Analysis was performed on 120 outpatient and inpatient POPs treated in our hospital between January and October 2013, where the patients were randomly divided into Qing’E group (QEF + Caltrate), Calcitriol group (Caltrate + Calcitriol soft capsules), and Compare group (Caltrate), each with a follow-up period of 1 year. Statistical analysis was then performed on bone mineral density, blood bone metabolic markers (β-CTX, N-MID, T-PINP) and changes in VDR mRNA expressions in the POPs before and after the treatments. Results: Prior to the treatments, bone mineral density and blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the 3 groups of POPs exhibited no statistically significant differences, and the blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the control group showed no statistically significant differences before and after the treatments. There were no significant differences in bone mineral density in the Qing’E group and the Calcitriol group before and after the treatments whereas the bone mineral density decreased in the control group after the treatments. As for blood β-CTX, N-MID, T-PINP and VDR mRNA expression, the measurements in POPs in the Qing’E group and the Calcitriol group were significantly higher than that of the control group. Conclusion: By adjusting the VDR mRNA expression, the QEF, a kidney-invigorating Chinese herbal formula, is capable of activating bone metabolism to prohibit further losses of bone mass, thereby preventing the deterioration of osteoporosis.展开更多

METHODS Patients who underwent upper gastrointestinal endoscopy at the First Affiliated Hospital,College of Medicine,Zhejiang University,Hangzhou,China during Jan 2009 to Nov 2016 were included. General characteristics as well as clinical data were collected,including blood routine,serum biochemical analysis,endoscopic findinds,histological evaluation and comorbiditie. Statistical analyses was performed using SPSS 20.0 software for Windows(IBM Inc.,Chicago,IL,United States) using Student's t-test,Mann-Whitney U test,χ2 test,univariable and multivariable logistic analysis. 2-tailed P value less than 0.05 was considered to be statistically significant. RESULTS A total of 176006 endoscopies were retrieved and we included 1370 xanthelasma participants(703 men,667 women) in this study. Prevalence of xanthelasma was 0.78% with average age of 56.6 ± 11.2 years. Chief complaint of xanthelasma consisted abdominal pain (24.2%),up-abdominal discomfort(14.1%),abdominal distention(10.1%),dyspepsia(9.1%),et al. Most xanthelasma occurred as single lesion in gastric antrum. Xanthelasma patients witnessed higher Helicobacter pylori(H. pylori) infection rate,more of other gastric lesions including atrophy,intestinal metaplasia and dysplasia(P < 0.01). In xanthelasma patients,serum carcinoembryonic antigen,triglyceride,fasting glucose,neutrophil,neutrophil-to-lymphocyte ratio were significantly higher,and high density lipoprotein-cholesterol,lymphocyte was lower(P < 0.05). Xanthelasma accompanied with more fatty liver disease and hepatic cyst,but fewer gallbladder polyp(P < 0.05). In logistic regression,it revealed that fasting plasma glucose(OR = 3.347,1.170-9.575,P < 0.05),neutrophil(OR = 1.617,1.003-2.605,P < 0.05),and carcinoembryonic antigen(OR = 2.011,1.236-3.271,P < 0.01) were all independent risk factors in xanthelasma. CONCLUSION Current study described a large xanthelasma cohort in Chinese population,revealed its relationship with H. pylori infection,carcinogenesis,metabolic dysfunction and inflammation as well.展开更多

Methods: A total of 177 postmenopausal women participated in a cross-sectional study. They were interviewed to collect anthropometric and demographic characteristics. BMD was measured and biochemical parameters were estimated in fasting blood samples. Univariate and multivariate analyses were used to examine the association between individual components of MetS and BMD. Results: Among 177 postmenopausal women, 116 (66%) had MetS. Women with MetS had significantly higher mean values of BMD and T scores at the total hip (P < 0.05) compared to women without MetS, which disappeared after adjustment for body weight, but not for age (P < 0.05). Features of the MetS other than waist circumference were not significantly related to BMD values at the three skeletal sites, except for diastolic blood pressure association with BMD at the femoral neck (r = 0.150, P < 0.05). BMD at the total hip was also positively associated with both of triglycerides (r = 0.157, P < 0.05) and fasting blood glucose (r = 0.193, P < 0.01). To identify the independent factors affecting the BMD at the 3 skeletal sites according to metabolic states, stepwise multiple linear regression analysis was performed. Conclusions: Body weight and osteocalcin were more strongly associated with bone mass than any other component of MetS in postmenopausal women. However, further studies seem to be needed to confirm their observation.展开更多

They are also one of the leading causes of morbidity and mortality. Although, different etiologic factors including excessive food intake and reduced physical activity have been well identified, they cannot explain the kinetics of epidemic evolution of obesity and diabetes with prevalence rates reaching pandemic proportions. Interestingly, convincing data have shown that environmental pollutants, specifically those endowed with endocrine disrupting activities, could contribute to the etiology of these multifactorial metabolic disorders. Within this review, we will recapitulate characteristics of endocrine disruption. We will demonstrate that metabolic disorders could originate from endocrine disruption with a particular focus on convincing data from the literature. Eventually, we will present how handling an original mouse model of chronic exposition to a mixture of pollutants allowed demonstrating that a mixture of pollutants each at doses beyond their active dose could induce substantial deleterious effects on several metabolic end-points. This proof-of-concept study, as well as other studies on mixtures of pollutants, stresses the needs for revisiting the current threshold model used in risk assessment which does not take into account potential effects of mixtures containing pollutants at environmental doses, e.g., the real life exposure. Certainly, more studies are necessary to better determine the nature of the chemicals to which humans are exposed and at which level, and their health impact. As well, research studies on substitute products are essential to identify harmless molecules.展开更多

As well as stress in adolescence can accentuate these disorders. Both human and rat structural changes have been demonstrated in the hippocampus, likewise, oxidative stress may be involved in these disturbances. The objective of this study is to see the impact of a high-fructose diet (PN21) associated with chronic mild stress (CMS) at the end of adolescence (PN55) on metabolic and affective disorders in rats Wistar. This study was performed on four groups of male rats: control group, CMS for five weeks (PN55), fructose for ten weeks (PN21) and fructose for ten weeks (PN21) associated with CMS for five weeks (PN55). These animals underwent behavioral tests to evaluate their affective states (open field test, Sucrose preference test). After sacrifice, the dosage of glucose, triglycerides and total cholesterol was performed at the prefrontal cortex (CPF) and also at the hippocampus;the dosage of nitric oxide (NO) was performed, too. The bulk of our results show that fructose induces metabolic disturbances;the CMS induces a state of depression-like, while the association potentiated metabolic disturbances, depression-like state and also inducing anxiety. This study has shown that fructose and CMS can disrupt the various functions of the body and their association can potentiate these disturbances.展开更多

Aim: To evaluate the impact of high sugar-fat diet in the development of metabolic-inflammatory disorders in non-obese animals. Methods: Male Wistar rats were distributed into two groups according to the diet: control and high sugar-fat for 30 weeks. It was analyzed: dietary efficiency;chow, water and caloric intake;metabolic and hormonal profile in plasma and inflammatory cytokines in epididymal adipose tissue. Data were compared by Student’s t test or by Mann-Whitney U test with p Results: HSF presented lower chow intake, higher water consumption and dietary efficiency with no difference in the caloric intake. The final body weight (FBW) and weight gain (WG) were lower in the HSF group and there was no difference in the adiposity index (AI). HSF diet-induced hyperglycemia and hyperinsulinemia with no difference for Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). Triglycerides, uric acid, adiponectin and leptin levels were higher in the HSF group. The HSF group showed increased interleukin-6 (IL-6) and tumoral necrosis factor-alpha (TNF-α) levels in epidydimal adipose tissue. The urinary protein-creatinine ratio and albuminuria were higher in the HSF group. Conclusion: HSF diet intake is directly involved in the development of metabolic-inflammatory disorders independent of obesity, dissociating the view that increased adiposity is the major risk factor for complications commonly found in obese individuals.展开更多

However, the detailed mechanisms regulating peri-implant bone remodeling at the bone-prosthesis interface remain elusive. To address this gap in knowledge, we evaluated the natural postoperative course of bone metabolism by using [18F] NaF positron emission tomography (PET)/computed tomography in 57 patients (104 joints) who underwent asymptomatic total knee arthroplasty (TKA). First, we measured total tracer uptake around TKA to determine the total bone metabolism (TBM) and used the ischial tuberosity as the reference tissue for normalization of PET images. Second, we calculated the TBM ratio (TBMR) by dividing the TBM by tracer uptake in the reference tissue. A moderate increase in TBMR was observed 4 - 5 days after implantation, and its intensity reached the maximum on the seventh postoperative day. The TBMR showed no differences until 12 weeks, after which it decreased slowly and returned to the basal levels. The new parameter TBMR and the unique pattern of postoperative metabolic changes in the bone around the prosthesis may help set accurate interpretation criteria to diagnose complications such as loosening or infections.展开更多

Method: The Medical Outcomes Study Short Form-36 (SF-36) health status questionnaire was used to measure the HRQoL and compare the mean scores of the questionnaire subscales and physical and mental component summaries (PCS and MCS) of 33 patients with MetS, 18 patients with MSDs, and 30 apparently healthy (AH) subjects. Regression analysis was used to measure the prediction power of the study group, age and gender of the participants in estimating the HRQoL. Results: Results showed that the mean scores of the physical subscales, the PCS, the mental subscales and MCS were arranged in descending order from AH subjects, patients with MetS, to patients with MSDs. The mean scores difference among the 3 study groups were statistically significant with the only exception for the general mental health (GMH) subscale (P = 0.404). The study group and age accounted for 41.8% of the variability of PCS while the study group accounted for 19.6% of the variability in the MCS. The resulted equation to estimate the PCS score was as follows: PCS = 113.18 - 12.85 (Group: 0 for AH, 1 for MetS, and 2 for MSDs) - 0.67 age. On the other hand the resulted equation to estimate the MCS score was as follows: MCS = 76.203 - 10.426 (Group: 0 for AH, 1 for MetS, and 2 for MSDs). Conclusion: Patients with MetS and patients with MSDs had lower HRQoL than AH subjects. All the physical and mental dimensions of HRQoL are negatively influenced with MetS and with MSDs with the only exception for the GMH subscale. The physical and mental burden of MSDs is more dominant. The study group and age can be used to predict the PCS while the study group can be used to predict the MCS.展开更多

In Low and Middle income countries (LMIC) the difficult access to some diagnostic tests makes the management of the metabolic emergencies challenging. The main objectives of this study were to assess the frequency and circumstances of occurrence and to describe the clinical picture associated with glucose, sodium and potassium disorders in neonates. Patients and Methods: Our study was a retrospective and descriptive study conducted in the neonatology unit of National Children Hospital Albert Royer in Dakar (Senegal) from January 1 to December 31, 2014. Results: The prevalence of the studied metabolic disorders was 46.7%. The most common metabolic disorder noted was Hyperglycemia followed by Hyponatremia. Thermoregulation disturbances were found particularly in newborns with serum sodium disorders (hyponatremia 33.5% and hypernatremia 59.7%). Neurological signs were noted in case of blood sugar abnormalities (hypoglycemia 26.1% and hyperglycemia 29.8%). Half of the newborns with hyperglycemia (82 cases/50%) had blood sugar levels greater than or equal to 2 g/l. Hypernatremia was severe (Serum sodium> 180 mmol/l) in 12 neonates (16.7%). The main diagnoses retained were sepsis (159 cases/45.4%), prematurity (96 cases/27.4%), intrauterine growth retardation (66 cases/18.9%), malformations (63 cases/18%), perinatal asphyxia (44 cases/12.6%) and malnutrition (36 cases/10.3%). For most metabolic disorders, the correction was late and was done beyond 48 hours. On average, the correction time varied between 3 hours and 6 days. The most frequent complications were cerebral edema (12 cases), brain death (8 cases) and increased intracranial pressure (3 cases). The most lethal disorders were Hyperkalemia followed by Hyperglycemia. Conclusion: Metabolic disorders especially glucose, sodium and potassium disorders are common in newborns. They are medical emergencies that can lead to vital instability and death. Their management is challenging in low-income countries due to the lack of adapted facilities and means to diagnose them. It is therefore important to improve the availability of technical methods and means of biological analysis in hospital laboratories and to monitor closely all newborns for early diagnosis of these disorders.展开更多

文摘Background:In this study,we used network pharmacology and molecular docking combined with vitro experiments to explore the potential mechanism of action of Gualou Qumai pill(GLQMP)against DKD.Methods:We screened effective compounds and drug targets using Chinese medicine systemic pharmacology database and analysis platform and Chinese medicine molecular mechanism bioinformatics analysis tools;and searched for DKD targets using human online Mendelian genetics and gene cards.The potential targets of GLQMP for DKD were obtained through the intersection of drug targets and disease targets.Cytoscape software was applied to build herbal medicine-active compound-target-disease networks and analyze them;protein-protein interaction networks were analyzed using the STRING database platform;gene ontology and Kyoto Encyclopedia of Genes and Genomes were used for gene ontology and gene and genome encyclopedia to enrich potential targets using the DAVID database;and the AutoDock Vina 1.1.2 software for molecular docking of key targets with corresponding key components.In vitro experiments were validated by CCK8,oil red O staining,TC,TG,RT-qPCR,and Western blot.Results:Through network pharmacology analysis,a total of 99 potential therapeutic targets of GLQMP for DKD and the corresponding 38 active compounds were obtained,and 5 core compounds were identified.By constructing the protein-protein interaction network and performing network topology analysis,we found that PPARA and PPARG were the key targets,and then we molecularly docked these two key targets with the 38 active compounds,especially the 5 core compounds,and found that PPARA and PPARG had good binding ability with a variety of compounds.In vitro experiments showed that GLQMP was able to ameliorate HK-2 cell injury under high glucose stress,improve cell viability,reduce TC and TG levels as well as decrease the accumulation of lipid droplets,and RT-qPCR and Western blot confirmed that GLQMP was able to promote the expression levels of PPARA and PPARG.Conclusion:Overall,this study revealed the active compounds,important targets and possible mechanisms of GLQMP treatment for DKD,and conducted preliminary verification experiments on its correctness,provided novel insights into the treatment of DKD by GLQMP.
文摘BACKGROUND Although percutaneous vertebral augmentation(PVA)is a commonly used procedure for treating vertebral compression fracture(VCF),the risk of vertebral refracture should be considered.Chronic kidney disease-mineral and bone disorder(CKD-MBD)is a systemic disease of mineral and bone metabolism.It is associated with an increased risk of fracture.Few studies have reported the use of PVA in patients with CKD-MBD.We herein report a rare case wherein the cemented vertebra and the adjacent vertebra refractured simultaneously in a CKD-MBD patient after PVA.CASE SUMMARY A 74-year-old man suffered from low back pain after taking a fall about 3 wk ago.According to physical examination,imaging and laboratory findings,diagnoses of T12 VCF,CKD-MBD,and chronic kidney disease stage 5 were established.He then received percutaneous vertebroplasty at T12 vertebra.Fourteen weeks later,he presented with T12 and L1 vertebral refractures caused by lumbar sprain.Once again,he was given PVA which was optimized for the refractured vertebrae.Although the short-term postoperative effect was satisfactory,he reported chronic low back pain again at the 3-month follow-up.CONCLUSION It is necessary that patients with CKD-MBD who have received PVA are aware of the adverse effects of CKD-MBD.It may increase the risk of vertebral refracture.Furthermore,the PVA surgical technique needs to be optimized according to the condition of the patient.The medium-and long-term effects of PVA remain uncertain in patients with CKD-MBD.
文摘Neonatal osteopenia is an important area of interest for neonatologists due to continuing increased survival of preterm infants. It can occur in high-risk infants such as preterm infants, infants on long-term diuretics or corticosteroids, and those with neuromuscular disorders. Complications such as rickets, pathological fractures, impaired respiratory function and poor growth in childhood can develop and may be the first clinical evidence of the condition. It is important for neonatologists managing such high-risk patients to regularly monitor biochemical markers for evidence of abnormal bone turnover and inadequate mineral intake in order to detect the early phases of impaired bone mineralization. Dual-energy X-ray absorptiometry has become an increasingly used research tool for assessing bone mineral density in children and neonates, but more studies are still needed before it can be used as a useful clinical tool. Prevention and early detection of osteopenia are key to the successful management of this condition and oral phosphate supplements should be started as soon as is feasible.
文摘Objectives: To study the partial mechanism of treating postmenopausal osteoporosis patients (POPs) using the ancient recipe of Qing’E Formula (QEF) by observing its effects on bone metabolic markers and VDR mRNA expression in primary POPs. Methods: Analysis was performed on 120 outpatient and inpatient POPs treated in our hospital between January and October 2013, where the patients were randomly divided into Qing’E group (QEF + Caltrate), Calcitriol group (Caltrate + Calcitriol soft capsules), and Compare group (Caltrate), each with a follow-up period of 1 year. Statistical analysis was then performed on bone mineral density, blood bone metabolic markers (β-CTX, N-MID, T-PINP) and changes in VDR mRNA expressions in the POPs before and after the treatments. Results: Prior to the treatments, bone mineral density and blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the 3 groups of POPs exhibited no statistically significant differences, and the blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the control group showed no statistically significant differences before and after the treatments. There were no significant differences in bone mineral density in the Qing’E group and the Calcitriol group before and after the treatments whereas the bone mineral density decreased in the control group after the treatments. As for blood β-CTX, N-MID, T-PINP and VDR mRNA expression, the measurements in POPs in the Qing’E group and the Calcitriol group were significantly higher than that of the control group. Conclusion: By adjusting the VDR mRNA expression, the QEF, a kidney-invigorating Chinese herbal formula, is capable of activating bone metabolism to prohibit further losses of bone mass, thereby preventing the deterioration of osteoporosis.

文摘AIM To gain knowledge of xanthelasma,a large populationbased study was conducted. METHODS Patients who underwent upper gastrointestinal endoscopy at the First Affiliated Hospital,College of Medicine,Zhejiang University,Hangzhou,China during Jan 2009 to Nov 2016 were included. General characteristics as well as clinical data were collected,including blood routine,serum biochemical analysis,endoscopic findinds,histological evaluation and comorbiditie. Statistical analyses was performed using SPSS 20.0 software for Windows(IBM Inc.,Chicago,IL,United States) using Student's t-test,Mann-Whitney U test,χ2 test,univariable and multivariable logistic analysis. 2-tailed P value less than 0.05 was considered to be statistically significant. RESULTS A total of 176006 endoscopies were retrieved and we included 1370 xanthelasma participants(703 men,667 women) in this study. Prevalence of xanthelasma was 0.78% with average age of 56.6 ± 11.2 years. Chief complaint of xanthelasma consisted abdominal pain (24.2%),up-abdominal discomfort(14.1%),abdominal distention(10.1%),dyspepsia(9.1%),et al. Most xanthelasma occurred as single lesion in gastric antrum. Xanthelasma patients witnessed higher Helicobacter pylori(H. pylori) infection rate,more of other gastric lesions including atrophy,intestinal metaplasia and dysplasia(P < 0.01). In xanthelasma patients,serum carcinoembryonic antigen,triglyceride,fasting glucose,neutrophil,neutrophil-to-lymphocyte ratio were significantly higher,and high density lipoprotein-cholesterol,lymphocyte was lower(P < 0.05). Xanthelasma accompanied with more fatty liver disease and hepatic cyst,but fewer gallbladder polyp(P < 0.05). In logistic regression,it revealed that fasting plasma glucose(OR = 3.347,1.170-9.575,P < 0.05),neutrophil(OR = 1.617,1.003-2.605,P < 0.05),and carcinoembryonic antigen(OR = 2.011,1.236-3.271,P < 0.01) were all independent risk factors in xanthelasma. CONCLUSION Current study described a large xanthelasma cohort in Chinese population,revealed its relationship with H. pylori infection,carcinogenesis,metabolic dysfunction and inflammation as well.
文摘Objective:To assess the effect of the adherence to medical treatment on urinary parameters in the 24-h metabolic study of patients with kidney stones.Methods:A retrospective,longitudinal,descriptive,and observational study was carried out by reviewing the hospital electronic medical record from 2014 to 2018.The adherence to drug treatment was measured 6 months after its initiation,and the numerical values of the metabolic studies were compared.Wilcoxon tests were performed to compare the difference before and after treatment.Results:Ninety patients were evaluated,with 73.3% of adherence.The 180-day overall adherence rate was 61.2% in patients treated with a single drug and 85.4% in patients treated with multiple drugs.There is a statistically significant increase in citrate levels in patients with good adherence in comparison with non-adherent patients(p=0.031 vs.p=0.528).Conclusions:Medical treatment and dietary measures in patients with kidney stones have an initial impact at 6 months on the values of the main urinary metabolic alterations that predispose to calculi formation;the most significant is seen in those patients with adherence to medical treatment for hypocitraturia.
文摘Aim: To examine the association between individual components of metabolic syndrome (MetS) and bone mineral density (BMD) among postmenopausal women. Methods: A total of 177 postmenopausal women participated in a cross-sectional study. They were interviewed to collect anthropometric and demographic characteristics. BMD was measured and biochemical parameters were estimated in fasting blood samples. Univariate and multivariate analyses were used to examine the association between individual components of MetS and BMD. Results: Among 177 postmenopausal women, 116 (66%) had MetS. Women with MetS had significantly higher mean values of BMD and T scores at the total hip (P < 0.05) compared to women without MetS, which disappeared after adjustment for body weight, but not for age (P < 0.05). Features of the MetS other than waist circumference were not significantly related to BMD values at the three skeletal sites, except for diastolic blood pressure association with BMD at the femoral neck (r = 0.150, P < 0.05). BMD at the total hip was also positively associated with both of triglycerides (r = 0.157, P < 0.05) and fasting blood glucose (r = 0.193, P < 0.01). To identify the independent factors affecting the BMD at the 3 skeletal sites according to metabolic states, stepwise multiple linear regression analysis was performed. Conclusions: Body weight and osteocalcin were more strongly associated with bone mass than any other component of MetS in postmenopausal women. However, further studies seem to be needed to confirm their observation.

文摘BACKGROUND Bone loss and osteoporosis are commonly described as extra-intestinal manifestations of inflammatory bowel disease(IBD).Jianpi Qingchang Bushen decoction(JQBD)is a prescription used in clinical practice.However,further studies are needed to determine whether JQBD regulates the receptor activator of nuclear factor kappa B(NF-κB)(RANK)/receptor activator of NF-κB ligand(RANKL)/osteoprotegerin(OPG)pathways and could play a role in treating IBD-induced bone loss.AIM To evaluate the therapeutic effect of JQBD in IBD-induced bone loss and explore the underlying mechanisms.METHODS An IBD-induced bone loss model was constructed by feeding 126-to-8-wk-old interleukin-10(IL-10)-knockout mice with piroxicam for 10 d.The mice were randomly divided into model and JQBD groups.We used wild-type mice as a control.The JQBD group was administered the JQBD suspension for 2 wk by gavage,while the control and model groups were given normal saline at the corresponding time points.All mice were killed after the intervention.The effect of JQBD on body weight,disease activity index(DAI),and colon length was analyzed.Histopathological examination,colon ultrastructure observation,and micro-computed tomographic scanning of the lumbar vertebrae were performed.The gene expression of NF-κB,tumor necrosis factor-α(TNF-α),IL-1β,IL-6,and IL-8 in the colon was evaluated by real-time polymerase chain reaction.Colon samples were assessed by Western blot for the expression of RANKL,OPG,RANK,and NF-κB proteins.RESULTS The model group lost body weight,had a shorter colon,and showed a dramatic increase in DAI score,whereas JQBD had protective and therapeutic effects.Treatment with JQBD significantly improved inflammatory cell infiltration and reduced crypt abscess and ulcer formation.Threedimensional imaging of the vertebral centrum in the model group revealed a lower bone mass,loose trabeculae,and“rod-shaped”changes in the structure compared to the control group and JQBD groups.The bone volume/total volume ratio and bone mineral density were significantly lower in the model group than in the control group.JQBD intervention downregulated the NF-κB,TNF-α,IL-1β,IL-6,and IL-8 m RNA expression levels.The RANKL and OPG protein levels were also improved.CONCLUSION JQBD reduces inflammation of the colonic mucosa and inhibits activation of the RANK/RANKL/OPG signaling pathway,thereby reducing osteoclast activation and bone resorption and improving bone metabolism.

文摘Obesity and associated metabolic disorders represent a major societal challenge in health and quality of life with large psychological consequences in addition to physical disabilities. They are also one of the leading causes of morbidity and mortality. Although, different etiologic factors including excessive food intake and reduced physical activity have been well identified, they cannot explain the kinetics of epidemic evolution of obesity and diabetes with prevalence rates reaching pandemic proportions. Interestingly, convincing data have shown that environmental pollutants, specifically those endowed with endocrine disrupting activities, could contribute to the etiology of these multifactorial metabolic disorders. Within this review, we will recapitulate characteristics of endocrine disruption. We will demonstrate that metabolic disorders could originate from endocrine disruption with a particular focus on convincing data from the literature. Eventually, we will present how handling an original mouse model of chronic exposition to a mixture of pollutants allowed demonstrating that a mixture of pollutants each at doses beyond their active dose could induce substantial deleterious effects on several metabolic end-points. This proof-of-concept study, as well as other studies on mixtures of pollutants, stresses the needs for revisiting the current threshold model used in risk assessment which does not take into account potential effects of mixtures containing pollutants at environmental doses, e.g., the real life exposure. Certainly, more studies are necessary to better determine the nature of the chemicals to which humans are exposed and at which level, and their health impact. As well, research studies on substitute products are essential to identify harmless molecules.
文摘An early unbalanced nutritional diet can induce affective disorders in adulthood. As well as stress in adolescence can accentuate these disorders. Both human and rat structural changes have been demonstrated in the hippocampus, likewise, oxidative stress may be involved in these disturbances. The objective of this study is to see the impact of a high-fructose diet (PN21) associated with chronic mild stress (CMS) at the end of adolescence (PN55) on metabolic and affective disorders in rats Wistar. This study was performed on four groups of male rats: control group, CMS for five weeks (PN55), fructose for ten weeks (PN21) and fructose for ten weeks (PN21) associated with CMS for five weeks (PN55). These animals underwent behavioral tests to evaluate their affective states (open field test, Sucrose preference test). After sacrifice, the dosage of glucose, triglycerides and total cholesterol was performed at the prefrontal cortex (CPF) and also at the hippocampus;the dosage of nitric oxide (NO) was performed, too. The bulk of our results show that fructose induces metabolic disturbances;the CMS induces a state of depression-like, while the association potentiated metabolic disturbances, depression-like state and also inducing anxiety. This study has shown that fructose and CMS can disrupt the various functions of the body and their association can potentiate these disturbances.
文摘Background: The modern dietary habit, which is rich in refined carbohydrates and saturated fats, increases the risk of chronic diseases due to the proinflammatory effect of these nutrients. Aim: To evaluate the impact of high sugar-fat diet in the development of metabolic-inflammatory disorders in non-obese animals. Methods: Male Wistar rats were distributed into two groups according to the diet: control and high sugar-fat for 30 weeks. It was analyzed: dietary efficiency;chow, water and caloric intake;metabolic and hormonal profile in plasma and inflammatory cytokines in epididymal adipose tissue. Data were compared by Student’s t test or by Mann-Whitney U test with p Results: HSF presented lower chow intake, higher water consumption and dietary efficiency with no difference in the caloric intake. The final body weight (FBW) and weight gain (WG) were lower in the HSF group and there was no difference in the adiposity index (AI). HSF diet-induced hyperglycemia and hyperinsulinemia with no difference for Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). Triglycerides, uric acid, adiponectin and leptin levels were higher in the HSF group. The HSF group showed increased interleukin-6 (IL-6) and tumoral necrosis factor-alpha (TNF-α) levels in epidydimal adipose tissue. The urinary protein-creatinine ratio and albuminuria were higher in the HSF group. Conclusion: HSF diet intake is directly involved in the development of metabolic-inflammatory disorders independent of obesity, dissociating the view that increased adiposity is the major risk factor for complications commonly found in obese individuals.
文摘Insulin,a small protein with 51 amino acids synthesized by pancreatic β-cells,is crucial to sustain glucose homeostasis at biochemical and molecular levels.Numerous metabolic dysfunctions are related to insulin-mediated altered glucose homeostasis.One of the significant pathophysiological conditions linked to the insulin associated disorder is diabetes mellitus(DM)(type 1,type 2,and gestational).Insulin resistance(IR)is one of the major underlying causes of metabolic disorders despite its association with several physiological conditions.Metabolic syndrome(MS)is another pathophysiological condition that is associated with IR,hypertension,and obesity.Further,several other pathophysiological disorders/diseases are associated with the insulin malfunctioning,which include polycystic ovary syndrome,neuronal disorders,and cancer.Insulinomas are an uncommon type of pancreatic β-cell-derived neuroendocrine tumor that makes up 2% of all pancreatic neoplasms.Literature revealed that different biochemical events,molecular signaling pathways,microRNAs,and microbiota act as connecting links between insulin disorder and associated pathophysiology such as DM,insuloma,neurological disorder,MS,and cancer.In this review,we focus on the insulin-related disorders and the underlying mechanisms associated with the pathophysiology.

文摘OBJECTIVE Cisplatin is a formidable chemotherapy agent widely applying in antineoplastic treatments,but its side effects often limit the clinical usage.Metabolic disorders are one of the side effects induced by cisplatin,which closely relate to the onset of chemotherapy-induced anorexia(CIA)in cancer patients but lacks effective controls.Liujunzi decoction(LJZD)is a traditional Chinese formula that has a promising effect in treating CIA.However,whether LJZD ameliorates CIA through adjusting cisplatin-induced metabolic disorders remain unknow.The present study evaluated the mechanism of cisplatin-induced metabolic disorders,and the effect of LJZD in ameliorating these disturbances.METHODS 42 male Sprague-Dawley(SD)rats(180-220 g)were randomly divided into 3 groups:normal control group(distilled water+saline),model group(distilled water+cisplatin),LJZD group(4.8 g·kg^(-1)Liujunzi decoction ingredients+cisplatin).Intragastrical administered each drug twice a day(7∶00-19∶00)since day 0 for 4 d,animals were intraperitoneal injected with cisplatin 6 mg·kg^(-1)1 h after administration while normal control groups were injected with same volume of saline.On day 3,each group was anesthetized with pentobarbital sodium 45 mg·kg^(-1)(ip),and blood samples were collected from aorta abdominalis.Then the samples were analyzed using an LC-ESI-MS/MS system.Significantly regulated metabolites between groups were determined by VIP≥1 and absolute Log2FC(fold change)≥1.Identified metabolites were mapped to Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway database using Metaboanalyst 5.0(https://www.metaboanalyst.ca/).RESULTS A total of 133,77 and 32 differential metabolites were filtrated in control vs model,control vs LJZD and model vs LJZD groups respectively.Comparing to control,the levels of hexadecanoic acid(Log2FC=6.3153),linoleic acid(Log2FC=5.3478),and 8,11-icosadienoic acid(Log2FC=5.2342)significantly increased,and the levels of N-acetyl-L-tyrosine(Log2FC=-2.6283),cinnamic acid(Log2FC=-2.3381),N-acetylphenylalanine(Log2FC=-2.2501)significantly decreased in model group.The KEGG pathway enrichments of these metabolites indicated that,cisplatin-induced metabolic disorders by disturbing metabolism pathways such as linoleic acid metabolism,biosynthesis of unsaturated fatty acids,and phenylalanine metabolism,which suggested that the onset of CIA was partly associated with the metabolic disorders of linoleic acid,unsaturated fatty acids,and phenylalanine.Compared to control,treatment of LJZD significantly increased the levels of 4-hydroxytryptamine(Log2FC=12.0186),hexadecanoic acid(Log2FC=5.7412),linoleic acid(Log2FC=5.1877)and significantly decreased the levels of N-acetylmethionine(Log2FC=-1.7317),2-aminoethanesulfinic acid(Log2FC=-1.6578),N-acetyl-L-tyrosine(Log2FC=-1.5355).And comparing to the model group,4-hydroxytryptamine(Log2FC=12.0186),7,12-diketocholic acid(Log2FC=2.0998),N-acetylneuraminic acid(Log2FC=2.0560)markedly increased,and 3-hydroxy-3-methylpentane-1(Log2FC=-1.9202),5-dioic acid(Log2FC=-1.7166),N-isovaleroylglycine,hexanoyl glycine(Log2FC=-1.4958)markedly decreased in LJZD group.It was worth noting that,there were 23 differential metabolites filtrated both in control vs model and model vs LJZD groups,which were the key metabolites of LJZD in treating CIA.Among these 23 common metabolites,there were 16 metabolites excluding the control vs LJZD group,that was,LJZD had no effect in normal rats while being able to ameliorated cisplatin-induced metabolic disorders by regulating these 16 metabolites.Cisplatin-induced downregulation of 11 metabolites such as hydrocinnamic acid,(±)12(13)epoxy-9Z-octadecenoic acid,cinnamic acid were upregulated after LJZD treatment,and cisplatin-induced upregulation of imidazoleacetic acid,2′-deoxycytidine-5′-monophosphate and other 5 metabolites were downregulated by LJZD.The KEGG pathway analysis indicated that the linoleic acid metabolism,histidine metabolism,and pyrimidine metabolism were the most enriched metabolic pathway.Thus,cisplatin-induced metabolic disturbances mainly by disturbing linoleic acid metabolism,histidine metabolism,and pyrimidine metabolism,and LJZD interacted with these metabolic pathways to reduce metabolic disorders and thus ameliorated CIA.CONCLUSION Cisplatin-induced anorexia was closely related to the metabolic disorders of linoleic acid metabolism,biosynthesis of unsaturated fatty acids,and phenylalanine metabolism.The mechanism of LJZD in ameliorating CIA was in concerned with the metabolic adjustments,relating to the regulation of linoleic acid metabolism,histidine metabolism,and pyrimidine metabolism.

文摘This experiment was conducted to investigate the effect of dietary calcium(Ca)or phosphorus(P)deficiency on bone development and related Ca or P metabolic utilization parameters of broilers from 22 to 42 days of age based on our previous study,which indicated that dietary Ca or P deficiency impaired the bone development by regulating related Ca or P metabolic utilization parameters of broilers from 1 to 21 days of age.A total of 504 one-day-old Arbor Acres male broilers were randomly assigned to 1 of 4 treatments with 7 replicates in a completely randomized design,and fed the normal control and Ca-or P-deficient diets from 1 to 21 days of age.At 22 days of age,the broilers were further fed the normal control diet(0.90%Ca+0.35%non-phytate P(NPP)),the P-deficient diet(0.90%Ca+0.18%NPP),the Ca-deficient diet(0.30%Ca+0.35%NPP)or the Ca and P-deficient diet(0.30%Ca+0.18%NPP),respectively.The results showed that dietary Ca or P deficiency decreased(P<0.05)tibia bone mineral density(BMD),bone breaking strength(BBS),ash content,tibia ash Ca content and serum P content on days 28 and 42,but increased(P<0.05)tibia alkaline phosphatase(ALP)activity of broilers on day 42 compared with the control group.Furthermore,the broilers fed the P-deficient diet had the lowest(P<0.05)tibia BMD,BBS,ash content,serum P content and the highest(P<0.05)serum Ca content on day 28 compared with those fed the Ca-deficient or Ca and P-deficient diets.The results from the present study indicated that the bone development and related Ca or P metabolic utilization parameters of broilers were the most sensitive to dietary P deficiency,followed by dietary Ca deficiency or Ca and P-deficiency;dietary Ca or P deficiency impaired the bone development possibly by regulating serum Ca and P contents as well as tibia Ca content and ALP activity of broilers from 22 to 42 days of age.
文摘Artificial joint replacement surgery is the orthopedic procedure of choice to relieve pain, correct joint deformities, and help patients resume everyday activities. However, the detailed mechanisms regulating peri-implant bone remodeling at the bone-prosthesis interface remain elusive. To address this gap in knowledge, we evaluated the natural postoperative course of bone metabolism by using [18F] NaF positron emission tomography (PET)/computed tomography in 57 patients (104 joints) who underwent asymptomatic total knee arthroplasty (TKA). First, we measured total tracer uptake around TKA to determine the total bone metabolism (TBM) and used the ischial tuberosity as the reference tissue for normalization of PET images. Second, we calculated the TBM ratio (TBMR) by dividing the TBM by tracer uptake in the reference tissue. A moderate increase in TBMR was observed 4 - 5 days after implantation, and its intensity reached the maximum on the seventh postoperative day. The TBMR showed no differences until 12 weeks, after which it decreased slowly and returned to the basal levels. The new parameter TBMR and the unique pattern of postoperative metabolic changes in the bone around the prosthesis may help set accurate interpretation criteria to diagnose complications such as loosening or infections.
文摘Aim: This work aimed to study the influence of two chronic health conditions, metabolic syndrome (MetS) and musculoskeletal disorders (MSDs), on the health-related quality of life (HRQoL) of Saudis. Method: The Medical Outcomes Study Short Form-36 (SF-36) health status questionnaire was used to measure the HRQoL and compare the mean scores of the questionnaire subscales and physical and mental component summaries (PCS and MCS) of 33 patients with MetS, 18 patients with MSDs, and 30 apparently healthy (AH) subjects. Regression analysis was used to measure the prediction power of the study group, age and gender of the participants in estimating the HRQoL. Results: Results showed that the mean scores of the physical subscales, the PCS, the mental subscales and MCS were arranged in descending order from AH subjects, patients with MetS, to patients with MSDs. The mean scores difference among the 3 study groups were statistically significant with the only exception for the general mental health (GMH) subscale (P = 0.404). The study group and age accounted for 41.8% of the variability of PCS while the study group accounted for 19.6% of the variability in the MCS. The resulted equation to estimate the PCS score was as follows: PCS = 113.18 - 12.85 (Group: 0 for AH, 1 for MetS, and 2 for MSDs) - 0.67 age. On the other hand the resulted equation to estimate the MCS score was as follows: MCS = 76.203 - 10.426 (Group: 0 for AH, 1 for MetS, and 2 for MSDs). Conclusion: Patients with MetS and patients with MSDs had lower HRQoL than AH subjects. All the physical and mental dimensions of HRQoL are negatively influenced with MetS and with MSDs with the only exception for the GMH subscale. The physical and mental burden of MSDs is more dominant. The study group and age can be used to predict the PCS while the study group can be used to predict the MCS.
文摘Introduction: Metabolic neonatal adaptation is a complex phenomenon and metabolic disorders can be frequent in immature newborns or in life-threatening situations. In Low and Middle income countries (LMIC) the difficult access to some diagnostic tests makes the management of the metabolic emergencies challenging. The main objectives of this study were to assess the frequency and circumstances of occurrence and to describe the clinical picture associated with glucose, sodium and potassium disorders in neonates. Patients and Methods: Our study was a retrospective and descriptive study conducted in the neonatology unit of National Children Hospital Albert Royer in Dakar (Senegal) from January 1 to December 31, 2014. Results: The prevalence of the studied metabolic disorders was 46.7%. The most common metabolic disorder noted was Hyperglycemia followed by Hyponatremia. Thermoregulation disturbances were found particularly in newborns with serum sodium disorders (hyponatremia 33.5% and hypernatremia 59.7%). Neurological signs were noted in case of blood sugar abnormalities (hypoglycemia 26.1% and hyperglycemia 29.8%). Half of the newborns with hyperglycemia (82 cases/50%) had blood sugar levels greater than or equal to 2 g/l. Hypernatremia was severe (Serum sodium> 180 mmol/l) in 12 neonates (16.7%). The main diagnoses retained were sepsis (159 cases/45.4%), prematurity (96 cases/27.4%), intrauterine growth retardation (66 cases/18.9%), malformations (63 cases/18%), perinatal asphyxia (44 cases/12.6%) and malnutrition (36 cases/10.3%). For most metabolic disorders, the correction was late and was done beyond 48 hours. On average, the correction time varied between 3 hours and 6 days. The most frequent complications were cerebral edema (12 cases), brain death (8 cases) and increased intracranial pressure (3 cases). The most lethal disorders were Hyperkalemia followed by Hyperglycemia. Conclusion: Metabolic disorders especially glucose, sodium and potassium disorders are common in newborns. They are medical emergencies that can lead to vital instability and death. Their management is challenging in low-income countries due to the lack of adapted facilities and means to diagnose them. It is therefore important to improve the availability of technical methods and means of biological analysis in hospital laboratories and to monitor closely all newborns for early diagnosis of these disorders.
