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

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

Conducted over a period of six months, from February 18 to July 18, 2021, this prospective and descriptive cross-sectional study involved 220 diabetic patients. Among these, 48 patients (22%) maintained balanced glucose levels (2 g/l). Positive glycosuria was observed in 54% of the patients, whereas 46% demonstrated normal glycosuria. An analysis of urinary parameters revealed that 15% of the patients had abnormal Ketone Bodies. Normal HbA1c levels (9%) HbA1c levels. Hematological assessments indicated significant variation: 56% of the patients had low hemoglobin levels, 4% suffered from hyper-eosinophilia, and 1% each from hyper-basophilia and hyper-hemoglobinemia. The anemic profile was characterized as mild anemia in 75%, moderate anemia in 20%, and severe anemia in 5%. Furthermore, 25% of patients were affected by Microcytic anemia and 75% by Normocytic anemia. Demographically, women constituted 65% of the study group compared to 35% of men. The most represented age bracket was 41 to 60 years, accounting for 52% of the patients, while those between 61 and 80 years comprised 36%. Every district in Kindia was impacted by diabetes.展开更多

The World H...Background: Obesity has become a serious global public health challenge, given that it leads to various adverse health outcomes that include cardiovascular illnesses, diabetes, and certain types of cancer. The World Health Organization (WHO) has estimated that, at the end of 2022, 1 out of every 8 individuals were obese, and that the global adult obesity rates have over doubled since 1990, even as the adolescent obesity rates have quadrupled. Thus, as of 2022, nearly 2.5 billion adults, aged 18 years and above, were overweight, with 890 million being obese. Obesity and overweight incidence rate has been gradually increasing over the years, presenting significant challenges to the healthcare systems throughout the globe. In this regard, the objective of this systematic review was to evaluate the effectiveness and safety of lifestyle modifications (diet and physical activity) and pharmacotherapy in promoting weight loss and improving metabolic health in overweight adults. Methodology: To attain the above stated study objective, a systematic evaluation of previous studies was carried out, particularly studies that assessed the effectiveness and safety of lifestyle modifications (diet and physical activity) and pharmacotherapy in promoting weight loss and improving metabolic health in overweight adults. The authors have used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in the selection of eligible studies for inclusion in the study. Results: The findings indicate that lifestyle interventions resulted in 5% - 10% weight reduction and significant improvements in metabolic indicators, while pharmacotherapy (GLP-1 receptor agonists) achieved up to 15% weight reduction and considerable metabolic health benefits. Further, comparative studies show lifestyle modifications provide overall health benefits, while medication is necessary for non-responders. Conclusion: Individualized treatment strategies are crucial, and further research is needed on long-term consequences and combination therapies.展开更多

The study aimed to investigate the prevalence of stroke and metabolic disorders in the middle-aged and elderly Chinese with type 2 diabetes. Methods A total of 4 629 subjects with type 2 diabetes （males： 1 917; females： 2 712） aged ≥ 40 years from Shijingshan district, Beijing, China from November 2011 to August 2012 were included in the study. Data on demographic information, lifestyle, history of diabetes mellitus, stroke, coronary heart disease, hypertension, and dyslipidemia were collected. The oral glucose tolerance test or a standard meal test was performed. Non-fatal stroke was reported by the subjects. The 2-tailed test was used, and P 〈0.05 was regarded as statistically significant. Results Prevalence of stroke in the subjects with type 2 diabetes was 5.5%. The prevalence of smoking, overweight or obesity, hypertension, and dyslipidemia was 41.0%, 65.8%, 67.4%, and 52.0% in males, and 2.2%, 65.5%, 69.5%, and 57.6% in females. Multivariate Logistic regression analysis showed that increased age, hypertension, diabetic duration, and overweight or obesity were positively correlated with stroke in the population with type 2 diabetes, whereas high- density lipoprotein cholesterol level was negatively correlated with stroke. After adjustment for age and gender, the odds ratio values of stroke in subjects having 1,2 or ≥3 of 4 risk factors, including smoking, overweight or obesity, hypertension and dyslipidemia, were 2.302 （95% CI： 0.789-6.712）, 4.089 （95% CI： 1.470-11.373）, 6.023 （95% CI： 2.176-16.666）, compared with subjects without any of the above 4 risk factors. Conclusions The prevalence of stroke was higher in middle-aged and eldedy Chinese with type 2 diabetes than that in the general population. With the aggregation of risk factors, the prevalence of stroke increased.展开更多

Recently, there has been a surge in the evidence indicating the correlation between the intestinal microbiota and development of these metabolic conditions apart from predisposing genetic and epigenetic factors. Gut microbiome is pivotal in controlling the host metabolism and physiology. But imbalances in the microbiota patterns lead to these disorders via several pathways. Animal and human studies so far have concentrated mostly on metagenomics for the whole microbiome characterization to understand how microbiome supports health in general. However, the accurate mechanisms connecting the metabolic disorders and alterations in gut microbial composition in host and the metabolites employed by the microorganisms in regulating the metabolic disorders is still vague. OBJECTIVE： The review delineates the latest findings about the role of gut microbiome to the pathophysiology of Obesity, IBD and Diabetes Mellitus. Here, we provide a brief introduction to the gut microbiome followed by the current therapeutic interventions in restoration of the disrupted intestinal microbiota. METHODS： A methodical PubMed search was performed using keywords like ＂gut microbiome,＂ ＂obesity, diabetes,＂ ＂IBD,＂ and ＂metabolic syndromes.＂ All significant and latest publications up to January 2018 were accounted for the review. RESULTS： Out of the 93 articles cited, 63 articles focused on the gut microbiota association to these disorders. The rest 18 literature outlines the therapeutic approaches in maintaining the gut homeostasis using probiotics, prebiotics and faecal microbial transplant （FMT）.

文摘Excessive fat deposition in obese subjects promotes the occurrence of metabolic diseases,such as type 2 diabetes mellitus(T2DM),cardiovascular diseases,and non-alcoholic fatty liver disease(NAFLD).Adipose tissue is not only the main form of energy storage but also an endocrine organ that not only secretes adipocytokines but also releases many extracellular vesicles(EVs)that play a role in the regulation of whole-body metabolism.Exosomes are a subtype of EVs,and accumulating evidence indicates that adipose tissue exosomes(AT Exos)mediate crosstalk between adipose tissue and multiple organs by being transferred to targeted cells or tissues through paracrine or endocrine mechanisms.However,the roles of AT Exos in crosstalk with metabolic organs remain to be fully elucidated.In this review,we summarize the latest research progress on the role of AT Exos in the regulation of metabolic disorders.Moreover,we discuss the potential role of AT Exos as biomarkers in metabolic diseases and their clinical application.

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The immune system plays a crucial role in protecting the body from invading pathogens and maintaining tissue homoeostasis.Maintaining homoeostatic lipid metabolism is an important aspect of efficient immune cell function and when disrupted immune cell function is impaired.There are numerous metabolic diseases whereby systemic lipid metabolism and cellular function is impaired.In the context of metabolic disorders,chronic inflammation is suggested to be a major contributor to disease progression.A major contributor to tissue dysfunction in metabolic disease is ectopic lipid deposition,which is generally caused by diet and genetic factors.Thus,we propose the idea,that similar to tissue and organ damage in metabolic disorders,excessive accumulation of lipid in immune cells promotes a dysfunctional immune system(beyond the classical foam cell)and contributes to disease pathology.Herein,we review the evidence that lipid accumulation through diet can modulate the production and function of immune cells by altering cellular lipid content.This can impact immune cell signalling,activation,migration,and death,ultimately affecting key aspects of the immune system such as neutralising pathogens,antigen presentation,effector cell activation and resolving inflammation.

文摘Postnatal growth retardation(PGR)frequently occurs during early postnatal development of piglets and induces high mortality.To date,the mechanism of PGR remains poorly understood.Adipose tissue-derived microbes have been documented to be associated with several disorders of metabolism and body growth.However,the connection between microbial disturbance of adipose tissue and pig PGR remains unclear.Here,we investigated piglets with PGR and found that the adipose tissue of PGR piglets was charac-terized by metabolism impairment,adipose abnormality,and specific enrichment of culturable bacteria from Proteobacteria.Gavage of Sphingomonas paucimobilis,a species of Sphingomonas genus from the alphaproteobacteria,induced PGR in piglets.Moreover,this bacterium could also lead to metabolic disorders and susceptibility to acute stress,resulting in weight loss in mice.Mechanistically,multi-omics analysis indicated the changes in lipid metabolism as a response of adipose tissue to abnormal microbial composition.Further experimental tests proved that one of the altered lipids phosphatidylethanolamines could rescue the metabolism disorder and growth retardation,thereby suppressing the amount of Sphingomonas in the adipose tissue.Together,these results highlight that the microbe–host crosstalk may regulate the metabolic function of adipose tissue in response to PGR.

文摘Polyhalogenated carbazoles(PHCZs)have been widely accepted as emerging pollutants,whereas their ecological and health risks remain uncertain.Herein,female and male Sprague-Dawley(SD)mice were treated with four typical PHCZs to investigate their negative consequences,along with alternations in gutmicrobiota to indicate underlyingmechanisms.In female mice,the relative liver weight ratio increased after four PHCZs exposure;2-bromocarbazole(2-BCZ)increased urine glucose level;3-bromocarbazole(3-BCZ)decreased the glucose and total cholesterol levels;3,6-dichlorocarbazole(3,6-DCCZ)decreased glucose level.The only disturbed biochemical index in male mice was the promoted alkaline phosphatase(ALP)level by 3,6-DCCZ.We also found that the differential blood biochemical indices were correlated with gut microbiota.3-BCZ and 3,6-DCCZ altered Bacteroidetes and Proteobacteria phyla in female and male mice,which were correlated with metabolic disorders.Our findings demonstrated the correlation between PHCZs induced potential hepatotoxicity andmetabolic disordersmay be due to their dioxin-like potentials and endocrine disrupting activities,and the gender differences might result from their estrogenic activities.Overall,data presented here can help to evaluate the ecological and health risks of PHCZs and reveal the underlying mechanisms.
文摘This study aims to enhance the healthcare services for diabetic patients in the administrative region of Kindia by suggesting dietary interventions to assist diabetics in better managing their condition. Conducted over a period of six months, from February 18 to July 18, 2021, this prospective and descriptive cross-sectional study involved 220 diabetic patients. Among these, 48 patients (22%) maintained balanced glucose levels (2 g/l). Positive glycosuria was observed in 54% of the patients, whereas 46% demonstrated normal glycosuria. An analysis of urinary parameters revealed that 15% of the patients had abnormal Ketone Bodies. Normal HbA1c levels (9%) HbA1c levels. Hematological assessments indicated significant variation: 56% of the patients had low hemoglobin levels, 4% suffered from hyper-eosinophilia, and 1% each from hyper-basophilia and hyper-hemoglobinemia. The anemic profile was characterized as mild anemia in 75%, moderate anemia in 20%, and severe anemia in 5%.

文摘Objective Microcystin-leucine-arginine(MC-LR)exposure induces lipid metabolism disorders in the liver.Secreted frizzled-related protein 5(SFRP5)is a natural antagonist of winglesstype MMTV integration site family,member 5A(Wnt5a)and an anti-inflammatory adipocytokine.In this study,we aimed to investigate whether MC-LR can induce lipid metabolism disorders in hepatocytes and whether SFRP5,which has anti-inflammatory effects,can alleviate the effects of hepatic lipid metabolism by inhibiting the Wnt5a/Jun N-terminal kinase(JNK)pathway.Methods We exposed mice to MC-LR in vivo to induce liver lipid metabolism disorders.Subsequently,mouse hepatocytes that overexpressed SFRP5 or did not express SFRP5 were exposed to MC-LR,and the effects of SFRP5 overexpression on inflammation and Wnt5a/JNK activation by MC-LR were observed.Results MC-LR exposure induced liver lipid metabolism disorders in mice and significantly decreased SFRP5 mRNA and protein levels in a concentration-dependent manner.SFRP5 overexpression in AML12cells suppressed MC-LR-induced inflammation.Overexpression of SFRP5 also inhibited Wnt5a and phosphorylation of JNK.Conclusion MC-LR can induce lipid metabolism disorders in mice,and SFRP5 can attenuate lipid metabolism disorders in the mouse liver by inhibiting Wnt5a/JNK signaling.

文摘Background: Obesity has become a serious global public health challenge, given that it leads to various adverse health outcomes that include cardiovascular illnesses, diabetes, and certain types of cancer. The World Health Organization (WHO) has estimated that, at the end of 2022, 1 out of every 8 individuals were obese, and that the global adult obesity rates have over doubled since 1990, even as the adolescent obesity rates have quadrupled. Thus, as of 2022, nearly 2.5 billion adults, aged 18 years and above, were overweight, with 890 million being obese. Obesity and overweight incidence rate has been gradually increasing over the years, presenting significant challenges to the healthcare systems throughout the globe. In this regard, the objective of this systematic review was to evaluate the effectiveness and safety of lifestyle modifications (diet and physical activity) and pharmacotherapy in promoting weight loss and improving metabolic health in overweight adults. Methodology: To attain the above stated study objective, a systematic evaluation of previous studies was carried out, particularly studies that assessed the effectiveness and safety of lifestyle modifications (diet and physical activity) and pharmacotherapy in promoting weight loss and improving metabolic health in overweight adults. The authors have used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in the selection of eligible studies for inclusion in the study. Results: The findings indicate that lifestyle interventions resulted in 5% - 10% weight reduction and significant improvements in metabolic indicators, while pharmacotherapy (GLP-1 receptor agonists) achieved up to 15% weight reduction and considerable metabolic health benefits. Further, comparative studies show lifestyle modifications provide overall health benefits, while medication is necessary for non-responders. Conclusion: Individualized treatment strategies are crucial, and further research is needed on long-term consequences and combination therapies.

文摘Metabolic disorders are classified clinically as a complex and varied group of diseases including metabolic syndrome,obesity,and diabetes mellitus.Fat toxicity,chronic inflammation,and oxidative stress,which may change cellular functions,are considered to play an essential role in the pathogenetic progress of metabolic disorders.Recent studies have found that cells secrete nanoscale vesicles containing proteins,lipids,nucleic acids,and membrane receptors,which mediate signal transduction and material transport to neighboring and distant cells.Exosomes,one type of such vesicles,are reported to participate in multiple pathological processes including tumor metastasis,atherosclerosis,chronic inflammation,and insulin resistance.Research on exosomes has focused mainly on the proteins they contain,but recently the function of exosome-associated microR NA has drawn a lot of attention.Exosomeassociated microR NAs regulate the physiological function and pathological processes of metabolic disorders.They may also be useful as novel diagnostics and therapeutics given their special features of non-immunogenicity and quick extraction.In this paper,we summarize the structure,content,and functions of exosomes and the potential diagnostic and therapeutic applications of exosome-associated micro RNAs in the treatment of metabolic disorders.
文摘Background：While combined oral contraceptives （COCs） are commonly used to treat polycystic ovary syndrome （PCOS）,comparative data regarding metabolic effects of different progestogens on this patient population are missing.This study aimed to compare the different effects of drospirenone （DRP）-containing COCs with cyproterone acetate （CPA）-containing COCs,combined with metformin and lifestyle modifications in women with PCOS and metabolic disorders.Methods：Ninety-nine women with PCOS and a metabolic disorder between January 2011 and January 2013 were enrolled into this prospective randomized clinical trial.Participants were randomized into two groups such as DRP-containing COCs,and CPA-containing COCs.Participants took COCs cyclically for 6 months,combined with metformin administration （1.5 g/d） and lifestyle modifications （diet and exercise）.Clinical measures and biochemical and hormone profiles were compared.Comparisons for continuous variables were evaluated with paired and unpaired Student＆#39;s t-tests.The Wilcoxon signed rank test was used when the data were not normally distributed.Analysis of covariance was used to control for age,body mass index （BMI）,and baseline data of each analyzed parameter when compared between the two groups.Results：A total of 68 patients have completed the study.The combination regimen of COCs,metformin,and lifestyle modifications in these patients resulted in a significant decrease in BMI,acne,and hirsutism scores when compared to baseline levels in both groups （P 〈 0.05）.Blood pressure （BP） was significantly different in the CPA group when compared to baseline （75.14 ± 6.77 mmHg vs.80.70 ± 5.60 mmHg,P 〈 0.01）,and after 6 months of treatment,only the change in systolic BP was significantly different between the two groups （4.00 [-6.00,13.00] mmHg vs.-3.50 [-13.00,9.00] mmHg,P =0.009）.Fasting glucose,fasting insulin,and homeostasis model assessment-insulin resistance decreased significantly in the DRP group （5.40 ± 0.41 mmol/L vs.5.21 ± 0.32 mmol/L,P =0.041;13.90 [10.50,18.40] μU/ml vs.10.75 [8.60,13.50] μU/ml,P =0.020;3.74 [2.85,4.23] vs.2.55 [1.92,3.40],P =0.008） but did not differ between the two groups.While individual lipid profiles increased in both groups,no statistically significant difference was observed.Conclusions：DRP-containing COCs combined with metformin and lifestyle modifications could better control BP and correct carbohydrate metabolism in women with PCOS and metabolic disorders compared with CPA-containing COCs.
文摘Background Stroke is now the most prevalent and debilitating disease affecting diabetic population in China. The study aimed to investigate the prevalence of stroke and metabolic disorders in the middle-aged and elderly Chinese with type 2 diabetes. Methods A total of 4 629 subjects with type 2 diabetes （males： 1 917; females： 2 712） aged ≥ 40 years from Shijingshan district, Beijing, China from November 2011 to August 2012 were included in the study. Data on demographic information, lifestyle, history of diabetes mellitus, stroke, coronary heart disease, hypertension, and dyslipidemia were collected. The oral glucose tolerance test or a standard meal test was performed. Non-fatal stroke was reported by the subjects. The 2-tailed test was used, and P 〈0.05 was regarded as statistically significant. Results Prevalence of stroke in the subjects with type 2 diabetes was 5.5%. The prevalence of smoking, overweight or obesity, hypertension, and dyslipidemia was 41.0%, 65.8%, 67.4%, and 52.0% in males, and 2.2%, 65.5%, 69.5%, and 57.6% in females. Multivariate Logistic regression analysis showed that increased age, hypertension, diabetic duration, and overweight or obesity were positively correlated with stroke in the population with type 2 diabetes, whereas high- density lipoprotein cholesterol level was negatively correlated with stroke. After adjustment for age and gender, the odds ratio values of stroke in subjects having 1,2 or ≥3 of 4 risk factors, including smoking, overweight or obesity, hypertension and dyslipidemia, were 2.302 （95% CI： 0.789-6.712）, 4.089 （95% CI： 1.470-11.373）, 6.023 （95% CI： 2.176-16.666）, compared with subjects without any of the above 4 risk factors. Conclusions The prevalence of stroke was higher in middle-aged and eldedy Chinese with type 2 diabetes than that in the general population. With the aggregation of risk factors, the prevalence of stroke increased.

文摘BACKGROUND： Metabolic disorders such as Obesity, Diabetes Type 2 （T2DM） and Inflammatory Bowel Diseases （IBD） are the most prevalent globally. Recently, there has been a surge in the evidence indicating the correlation between the intestinal microbiota and development of these metabolic conditions apart from predisposing genetic and epigenetic factors. Gut microbiome is pivotal in controlling the host metabolism and physiology. But imbalances in the microbiota patterns lead to these disorders via several pathways. Animal and human studies so far have concentrated mostly on metagenomics for the whole microbiome characterization to understand how microbiome supports health in general. However, the accurate mechanisms connecting the metabolic disorders and alterations in gut microbial composition in host and the metabolites employed by the microorganisms in regulating the metabolic disorders is still vague. OBJECTIVE： The review delineates the latest findings about the role of gut microbiome to the pathophysiology of Obesity, IBD and Diabetes Mellitus. Here, we provide a brief introduction to the gut microbiome followed by the current therapeutic interventions in restoration of the disrupted intestinal microbiota. METHODS： A methodical PubMed search was performed using keywords like ＂gut microbiome,＂ ＂obesity, diabetes,＂ ＂IBD,＂ and ＂metabolic syndromes.＂ All significant and latest publications up to January 2018 were accounted for the review. RESULTS： Out of the 93 articles cited, 63 articles focused on the gut microbiota association to these disorders. The rest 18 literature outlines the therapeutic approaches in maintaining the gut homeostasis using probiotics, prebiotics and faecal microbial transplant （FMT）. CONCLUSION： Metabolic disorders have intricate etiology and thus a lucid understanding of the complex host-microbiome inter-relationships will open avenues to novel therapeutics for the diagnosis, prevention and treatment of the metabolic diseases.
