Xanthine dehydrogenase/xanthine oxidase(XDH/XO) is rate-limiting enzyme of uric acid generation, and allopurinol was developed as a uric acid(UA) generation inhibitor in the 1950 s and has been routinely used for gout prevention since then. Serum UA levels are an important risk factor of disease progression for various diseases, including those related to lifestyle. Recently, other UA generation inhibitors such as febuxostat and topiroxostat were launched. The emergence of these novel medications has promoted new research in the field. Lifestyle-related diseases, such as metabolic syndrome or type 2 diabetes mellitus, often have a common pathological foundation. As such, hyperuricemia is often present among these patients. Many in vitro and animal studies have implicated inflammation and oxidative stress in UA metabolism and vascular injury because XDH/XO act as one of the major source of reactive oxygen species Many studies on UA levels and associated diseases implicate involvement of UA generation in disease onset and/or progression. Interventional studies for UA generation, not UA excretion revealed XDH/XO can be the therapeutic target forvascular injury and renal dysfunction. In this review, the relationship between UA metabolism and diabetic complications is highlighted.展开更多

The overall goal is to assess diabetes patients’ knowledge, attitudes, and behaviors about prevalent diabetic complications. This research used a descriptive qualitative methodology to assess diabetes complication knowledge, attitude, and practice. Ninety-eight diabetic patients were visiting the Egyptian Hospital in Mogadishu for four weeks. The data was collected using questionnaires. Finally, SPSS 20 was utilized for analysis. The research was performed from May to July 2020 with a non-probability sample size of 98 diabetics. The bulk of responders were aged 40 - 60 (36.7%). Type 2 was the most common (47.96%). 44.9% of respondents had diabetes for more than ten years. 60.2% had regular checkups, and 54.1 percent had therapy. 52% of participants were on a diet. 63.3% of respondents do not exercise often. However, most responders know the common issues (75%). Less than half of those polled had problems (41.8%). 22% incidence of Diabetic ketoacidosis. 78.6% of respondents know variables that decrease diabetes complications, whereas 22.4% do not. 37.8% of respondents saw a doctor for diabetes problems, whereas 62.2% did not. Diabetic patients’ knowledge, attitude, and practice were satisfactory for fundamental illness entanglements and self-testing. These findings may also be due to patient notification and, therefore, long-term illness that leads them to get acquainted with things alone. However, the tendency for regular exercise was low, which may produce more specific consequences of illness. <strong>Conclusion:</strong> We find that DM patients’ KAP was adequate in terms of knowledge of diabetic complications. These results may explain the patients’ long-standing illness, which forces them to discover things independently. At the same time, just a handful of them were familiar with vasculopathy and cardiovascular disorders. However, the researchers discovered low level of attitudes and practice toward regular exercise and insufficient levels of attitudes and practice toward diet management and treatment adherence. In general, this degree of KAP is suboptimal and requires further assessment of KAP obstacles in Somalia.展开更多

The Streptozocin （STZ）-induced diabetic mice were fed with high-AGEs diet. Diabetic characteristics, indicators 3f renal and cardiovascular functions, and pathohistology of pancreas, heart and renal were evaluated. AGEs/RAGE/ROS pathway parameters were determined. During the experiments, the diabetic mice exhibited typical characteristics including weight loss, polydipsia, polyphagia, polyuria, high-blood glucose, and low-serum insulin levels. However, high-AGEs diet effectively aggravated these diabetic sharacteristics. It also increased the 24-h urine protein levels, serum levels of urea nitrogen, creatinine, c-reactive protein （CRP）, low density lipoprotein （LDL）, tumor necrosis factor-a （TNF-a）, and interleukin-6 （IL-6） in the diabetic mice. High-AGEs diet deteriorated the histology of pancreas, heart, and kidneys, and caused structural alterations of endothelial ceils, mesangial cells and podocytes in renal ：ortex. Eventually, high-AGEs diet contributed to the high-AGE levels in serum and kidneys, high-levels of reactive oxygen species ＇,ROS） and low-levels of superoxide dismutase （SOD） in serum, heart, and kidneys. It also upregulated RAGE mRNA and protein expression in heart and kidneys. Our results showed that high-AGEs diet deteriorated vascular complications in the diabetic mice. The activation of AGEs/RAGE/ROS pathway may be involved in the pathogenesis of vascular complications in diabetes.展开更多

DATA SOURCES： The electronic databases of Pub Med, Medline, Embase, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Wanfang Database and the Chinese Biomedical Database were used to retrieve relevant studies without language restrictions. The search was conducted from the inception of each database to 7 October 2016. The key terms were（diabetic peripheral neuropathy or diabetic neuropathy or DPN） AND（α-lipoic acid or lipoic acid or thioctic acid） AND epalrestat. DATA SELECTION： All of the eligible studies met the following inclusion criteria：（1） Randomized controlled trials that compared efficacy and safety of epalrestat plus ALA combination therapy versus epalrestat or ALA monotherapy in patients with DPN.（2） The minimum duration of treatment was 2 weeks.（3） The DPN patients were diagnosed using the World Health Organization standardized type 2 diabetes mellitus and DPN criteria.（4） Studies contained at least one measure that could reflect the efficacy of the drug and nerve conduction velocities. Studies in which the control group used epalrestat or ALA combined with other drugs were excluded. Statistical analyses were performed using STATA software for meta-analysis. OUTCOME MEASURES： The primary outcomes were the therapeutic efficacy, median motor nerve conduction velocity（MNCV）, median sensory nerve conduction velocity（SNCV）, peroneal MNCV and peroneal SNCV.RESULTS： Twenty studies with 1894 DPN patients were included, including 864 patients in the ALA plus epalrestat group, 473 in the ALA group and 557 in the epalrestat group. The efficacy of ALA plus epalrestat combination therapy was superior to ALA and epalrestat monotherapies（RR = 1.29, 95% CI： 1.21–1.38; RR = 1.43, 95% CI： 1.34–1.54, respectively）. ALA plus epalrestat combination therapy also significantly improved median MNCV（WMD = 5.41, 95% CI： 2.07–8.75）, median SNCV（WMD = 5.87, 95% CI： 1.52–10.22）, peroneal MNCV（WMD = 5.59, 95% CI： 2.70–8.47） and peroneal SNCV（WMD = 4.57, 95% CI： 2.46–6.68）.CONCLUSION： ALA plus epalrestat combination therapy was superior to ALA and epalrestat monotherapies for clinical efficacy and nerve conduction velocities in patients with DPN.展开更多

文摘Objective To analyze the chemical constituents of Shanxiangyuanye(Turpiniae Folium)through liquid chromatography-tandem mass spectrometry(LC-MS/MS)method,and to evaluate their anti-oxidant,hypoglycemic,and anti-glycation activities related to diabetic complications.Methods The supernatant of Shanxiangyuanye(Turpiniae Folium)(TFS),obtained following water extraction and alcohol precipitation,was analyzed by LC-MS/MS.Antioxidant activity of TFS in vitro was evaluated using three experimental approaches:the 1,1-diphenyl-2-picrylhydrazyl(DPPH)radical scavenging assay,the 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS+)radical cation decolorization assay,and the hydroxyl(·OH)radical scavenging assay.To comprehensively evaluate hypoglycemic potential,α-glucosidase inhibition was measured to analyze in vitro hypoglycemic activity.Subsequently,in vitro models were developed to examine anti-glycation activity through the bovine serum albumin(BSA)-fructose(Fru),BSA-methylglyoxal(MGO),BSA-glyoxal(GO),and D-arginine(Arg)-MGO systems,with particular attention to the inhibitory effects of TFS.Furthermore,the concentrations of fructosamine,protein carbonyls,sulfhydryl groups,andβ-amyloid in the glycation solution were quantified using the BSA-Fru model following 7-d of incubation at 37°C.Results Using LC-MS/MS analysis in both positive and negative ion modes,we identified 750 chemical components in TFS,primarily including organic acids,amino acids,and their derivatives.In vitro activity studies demonstrated that TFS exhibited remarkable free radical scavenging capacity,with half-maximal inhibitory concentrations(IC_(50))of 0.47,1.56,and 0.36 mg/mL against DPPH,ABTS+,and·OH radicals,respectively.Regarding hypoglycemic activity,TFS dose-dependently inhibitedα-glucosidase activity(IC_(50)=0.21 mg/mL),displaying comparable efficacy to the clinical drug acarbose(IC_(50)=0.23 mg/mL).Notably,TFS intervened in the glycation process:IC_(50) values were 0.22,1.91–4.96,and 4.09 mg/mL in the BSAFru,BSA-MGO/GO,and Arg-MGO models,respectively,with the most prominent inhibitory effects observed in the BSA-Fru model.Furthermore,although TFS may not effectively preserve thiol groups in BSA or reduce thiol oxidation during glycation,it significantly reduces fructosamine levels(in a dose-dependent manner),decreasesβ-amyloid formation,and inhibits protein carbonylation(P<0.0001).Conclusion The findings demonstrate that TFS exhibits a complex chemical composition with potent antioxidant,hypoglycemic,and anti-glycation activities.These results provide compelling scientific evidence supporting TFS’s potential as a natural adjuvant for diabetes prevention and complication management,while laying a solid foundation for its applications in functional food development and adjunctive antidiabetic therapeutics.

文摘Background:Patients with type 2 diabetes are at high risk for developing multiple chronic complications.However,there is a lack of studies of the cumulative number of diabetic complications in China.Methods:A retrospective cohort study was performed from 2009 to 2021.Type 2 diabetes patients who were first diagnosed after the age of 35 years between January 1,2009,and December 31,2017,were included.Five states were defined according to the number of chronic complications:no(S0),one(S1),two(S2),three(S3),and four or more complications(S4).A multi-state Markov model was constructed to estimate transition probability,transition intensity,mean sojourn time,and the possible factors for each state.Results:The study included 32653 type 2 diabetes patients(mean age,59.59 years;15929(48.8%)male),and mean follow-up time of 7.75 years.In all,4375 transitions were observed.The 12-year transition probability of from state S0 to S1 was the lowest at 16.4%,while that from S2 to S3 was the highest,at 45.6%.Higher fasting blood glucose,lower high-density lipoprotein cholesterol,higher total cholesterol,and an unhealthy diet were associated with higher risk of progression from S0 to S1.Being female,less than 60 years old,weekly physical activity,and vegetarian diet decreased this risk.Being female and less than 60 years old reduced the likelihood of transition from S1 to S2,whereas lower high-density lipoprotein cholesterol increased this likelihood.Conclusions:Following the occurrence of two complications in type 2 diabetes patients,the risk for accumulating a third complication within a short time is significantly increased.It is important to take advantage of the stable window period when patients have fewer than two complications,strengthen the monitoring of blood glucose and blood lipids,and encourage patients to maintain good living habits to prevent further deterioration.
文摘Hyperuricemia have been thought to be caused by the ingestion of large amounts of purines, and prevention or treatment of hyperuricemia has intended to prevent gout. Xanthine dehydrogenase/xanthine oxidase(XDH/XO) is rate-limiting enzyme of uric acid generation, and allopurinol was developed as a uric acid(UA) generation inhibitor in the 1950 s and has been routinely used for gout prevention since then. Serum UA levels are an important risk factor of disease progression for various diseases, including those related to lifestyle. Recently, other UA generation inhibitors such as febuxostat and topiroxostat were launched. The emergence of these novel medications has promoted new research in the field. Lifestyle-related diseases, such as metabolic syndrome or type 2 diabetes mellitus, often have a common pathological foundation. As such, hyperuricemia is often present among these patients. Many in vitro and animal studies have implicated inflammation and oxidative stress in UA metabolism and vascular injury because XDH/XO act as one of the major source of reactive oxygen species Many studies on UA levels and associated diseases implicate involvement of UA generation in disease onset and/or progression. Interventional studies for UA generation, not UA excretion revealed XDH/XO can be the therapeutic target forvascular injury and renal dysfunction. In this review, the relationship between UA metabolism and diabetic complications is highlighted.

文摘Diabetes and its complications reduce quality of life and are life-limiting.At present,diabetes treatment consists of hypoglycemic agents to control blood glucose and the use of insulin-sensitizing drugs to overcome insulin resistance.In diabetes,autophagy is impaired and thus there is poor intracellular environment homeostasis.Pancreaticβ-cells and insulin target tissues are protected by enhancing autophagy.Autophagy decreasesβ-cell apoptosis,promotesβ-cell proliferation,and alleviates insulin resistance.Autophagy in diabetes is regulated by the mammalian target of rapamycin(mTOR)/adenosine 5′-monophosphate(AMP)-activated protein kinase(AMPK)pathway and others.Autophagy enhancers can likely be used as a treatment for diabetes and its complications.This review examines the evidence linking autophagy to diabetes.
文摘Diabetes and associated complications represent major global public health issues which are associated with impaired quality of life and premature death.Although some diabetic complications have decreased in the developed world,the majority are still prevalent,with an increasing trend in the developing world.Currently used therapies are mainly‘glucocentric’,focusing on the optimization of glycemic control to prevent,delay or manage diabetes-associated complications-other common comorbidities,such as dyslipidemia and hypertension are often underestimated.Although a number of novel therapeutic approaches have been reported recently,some of them have not received comparable attention in relation to either further studies or potential clinical implementation.This editorial briefly discusses some recent therapeutic approaches to the prevention and management of diabetes and its associated complications,as well as potential directions for future research and development in this area.
文摘Background:Diabetes mellitus is a chronic metabolic disease that is a risk factor for epidemic pathologies.Under hyperglycemic conditions,the enzyme aldose reductase catalyzes the formation of sorbitol in the metabolism of glucose via polyols,leading to the development of diabetic complications.Therefore,inhibitors of this enzyme are therapeutic targets for the prophylaxis and treatment of these conditions.Methods:In this study,a generalized linear regression model was developed to analyze flavonoids-obtained from a database-that have been tested as inhibitors of aldose reductase.In this sense,the molecular descriptors implemented in DRAGON and MATLAB software were used to determine the correlation between the chemical structure of the inhibitors and their pharmacological activity.The model was validated according to the Organisation for Economic Co-operation and Development Standards and subsequently used for the virtual screening of the flavonoids identified in Jatropha gossypiifolia L.Results:The proposed model showed a good fit for its statistical parameters(R2=0.95).In addition,it showed good predictive power(R2 ext=0.94)and robustness(Q2 LOO=0.92).The experimental chemical space wherein the predictions were reliable(domain of application)was also defined.Finally,the model was used to identify 10 flavonoids from Jatropha gossypiifolia L.as candidates for natural drugs.Compounds with a low probability of oral absorption were identified,among which the elagic acid biflavonoid showed the greatest promise(pIC50 predicted=9.75).Conclusion:The Jatropha gossypiifolia L.species harbors flavonoids with high potential as inhibitors of the aldose reductase enzyme,in which the biflavonoid ellagic acid was shown to be the most promising inhibitor of the aldose reductase enzyme,suggesting its possible use in the treatment of the late complications of diabetes mellitus.
文摘<em>Diabetes </em>is a chronic illness that occurs when the pancreas stops producing insulin or when the body cannot use the produced insulin. <em>Insulin</em> is a hormone produced by the pancreas that helps glucose from meals enters the body’s cells for energy. The overall goal is to assess diabetes patients’ knowledge, attitudes, and behaviors about prevalent diabetic complications. This research used a descriptive qualitative methodology to assess diabetes complication knowledge, attitude, and practice. Ninety-eight diabetic patients were visiting the Egyptian Hospital in Mogadishu for four weeks. The data was collected using questionnaires. Finally, SPSS 20 was utilized for analysis. The research was performed from May to July 2020 with a non-probability sample size of 98 diabetics. The bulk of responders were aged 40 - 60 (36.7%). Type 2 was the most common (47.96%). 44.9% of respondents had diabetes for more than ten years. 60.2% had regular checkups, and 54.1 percent had therapy. 52% of participants were on a diet. 63.3% of respondents do not exercise often. However, most responders know the common issues (75%). Less than half of those polled had problems (41.8%). 22% incidence of Diabetic ketoacidosis. 78.6% of respondents know variables that decrease diabetes complications, whereas 22.4% do not. 37.8% of respondents saw a doctor for diabetes problems, whereas 62.2% did not. Diabetic patients’ knowledge, attitude, and practice were satisfactory for fundamental illness entanglements and self-testing. These findings may also be due to patient notification and, therefore, long-term illness that leads them to get acquainted with things alone. However, the tendency for regular exercise was low, which may produce more specific consequences of illness. <strong>Conclusion:</strong> We find that DM patients’ KAP was adequate in terms of knowledge of diabetic complications. These results may explain the patients’ long-standing illness, which forces them to discover things independently. At the same time, just a handful of them were familiar with vasculopathy and cardiovascular disorders. However, the researchers discovered low level of attitudes and practice toward regular exercise and insufficient levels of attitudes and practice toward diet management and treatment adherence. In general, this degree of KAP is suboptimal and requires further assessment of KAP obstacles in Somalia.
文摘BACKGROUND Type 2 diabetes is one of the most prevalent chronic diseases worldwide,significantly impacting patients'quality of life.Current treatment options like metformin(MET)effectively counteract hyperglycemia but fail to alleviate diabetes-associated complications such as retinopathy,neuropathy,nephropathy,hepatopathy,and cardiovascular diseases.AIM To propose the supplementation of cholecalciferol(CHO)and taurine(TAU)to enhance MET efficacy in controlling diabetes while minimizing the risk of associated complications.METHODS The study involved sixty rats,including ten non-diabetic control rats and fifty experimental rats with type 2 diabetes induced by streptozotocin.The experimental rats were further subdivided into positive control and treatment subgroups.The four treatment groups were randomly allocated to a single MET treatment or MET combined with supplements either CHO,TAU,or both.RESULTS Diabetic rats exhibited elevated levels of glucose,insulin,Homeostasis Model Assessment of Insulin Resistance(HOMA-IR),glycated hemoglobin percentage,lipid markers,aspartate aminotransferase,and malondialdehyde,along with reduced levels of antioxidant enzymes(catalase and superoxide dismutase).The administration of CHO and TAU supplements alongside MET in diabetic rats led to a noticeable recovery of islet mass.The antioxidative,anti-inflammatory,and anti-apoptotic properties of the proposed combination therapy significantly ameliorated the aforementioned abnormalities.CONCLUSION The supplementation of CHO and TAU with MET showed the potential to significantly improve metabolic parameters and protect against diabetic complications through its antioxidative,anti-inflammatory,and antiapoptotic effects.
文摘BACKGROUND Social determinants of health are social and economic factors that influence health intervention outcomes.Type 2 diabetes is a highly prevalent disease,primarily affecting individuals in low-to-middle-income countries.However,the association between social determinants and cardiovascular complications in type 2 diabetes has not been widely studied.AIM To examine the relationship between social determinants of health and cardiovascular complications in individuals with type 2 diabetes.METHODS We conducted a retrospective cohort study with an analytical component at a national-level referral hospital for military personnel in Bogota,Colombia.Patients treated at the diabetes clinic between September 2021 and December 2022 who met the inclusion criteria were included.A total of 583 patients participated in the study.We performed descriptive,bivariate,and binary logistic regression analyses,adjusting for confounding variables.RESULTS Among the 583 patients included,urban residency[odds ratio(OR)=3.05,95%confidence interval(CI):1.01-9.20]and a middle or high educational level(OR=2.33,95%CI:1.14-4.72)were associated with an increased risk of coronary artery disease.Additionally,receiving diabetes education beyond that provided by the clinic(OR=2.15,95%CI:1.14-4.05)and lack of access to spaces for physical activity(OR=4.05,95%CI:1.31-12.5)were associated with a higher risk of diabetic nephropathy and cerebrovascular disease,respectively.CONCLUSION Programs for diabetes management should account for social determinants of health that contribute to cardiovascular complications and increased healthcare costs.Population-based studies are needed to guide targeted interventions and clarify causal relationships.

文摘The aim of this study was to investigate the effects of high-advanced glycation end products （AGEs） diet on diabetic vascular complications. The Streptozocin （STZ）-induced diabetic mice were fed with high-AGEs diet. Diabetic characteristics, indicators 3f renal and cardiovascular functions, and pathohistology of pancreas, heart and renal were evaluated. AGEs/RAGE/ROS pathway parameters were determined. During the experiments, the diabetic mice exhibited typical characteristics including weight loss, polydipsia, polyphagia, polyuria, high-blood glucose, and low-serum insulin levels. However, high-AGEs diet effectively aggravated these diabetic sharacteristics. It also increased the 24-h urine protein levels, serum levels of urea nitrogen, creatinine, c-reactive protein （CRP）, low density lipoprotein （LDL）, tumor necrosis factor-a （TNF-a）, and interleukin-6 （IL-6） in the diabetic mice. High-AGEs diet deteriorated the histology of pancreas, heart, and kidneys, and caused structural alterations of endothelial ceils, mesangial cells and podocytes in renal ：ortex. Eventually, high-AGEs diet contributed to the high-AGE levels in serum and kidneys, high-levels of reactive oxygen species ＇,ROS） and low-levels of superoxide dismutase （SOD） in serum, heart, and kidneys. It also upregulated RAGE mRNA and protein expression in heart and kidneys. Our results showed that high-AGEs diet deteriorated vascular complications in the diabetic mice. The activation of AGEs/RAGE/ROS pathway may be involved in the pathogenesis of vascular complications in diabetes.
文摘Diabetic cardiomyopathy(DCM),a complication of diabetes,poses a significant threat to public health,both its diagnosis and treatment presents challenges.Teneligliptin has promising applications and research implications in the treat-ment of diabetes mellitus.Zhang et al observed the therapeutic effect of tenelig-liptin on cardiac function in mice with DCM.They validated that teneligliptin’s mechanism of action in treating DCM involves cardiomyocyte protection and inhibition of NLRP3 inflammasome activity.Given that the NLRP3 inflammasome plays a crucial role in the onset and progression of DCM,it presents a promising therapeutic target.Nevertheless,further clinical validation is required to ascertain the preventive and therapeutic efficacy of teneligliptin in DCM.

文摘BACKGROUND Individuals with diabetes mellitus have a higher risk of developing malignant tumors,and diagnosing these tumors can be challenging.AIM To confirm the benefits of using peripherally inserted central catheters(PICCs)in contrast-enhanced computerized tomography(CECT)for diagnostic imaging in diabetic patients with malignant tumors and to provide a research basis for follow-up research.METHODS This retrospective study analyzed 204 diabetic patients with malignancies treated at The Second Affiliated Hospital,Jiangxi Medical College,Nanchang University,from January 2024 to June 2024.The patients were divided into two groups:A control group(n=102)with indwelling peripheral intravenous catheters and a research group(n=102)with high-pressure-resistant PICC.The study compared baseline data,the incidence of iodine contrast extravasation during CECT,the incidence of adverse events(discomfort,redness and swelling at the puncture site,and blood oozing),imaging quality,nursing time,intubation success rate,number of venipuncture attempts,and catheter maintenance cost.RESULTS Male patients accounted for 51.96%in the control group and 55.88%in the research group;the average age was(59.68±11.82)years in the control group and(61.41±12.92)years in the research group;the proportions of lung cancer,colorectal cancer,and gastric cancer patients in the control group were 42.16%,38.24%,and 19.61%,respectively,while those in the research group were 34.31%,37.25%,and 28.43%,respectively.Except for the gender distribution,age,and cancer type mentioned above,other general information such as underlying diseases,puncture location,and long-term chemotherapy shows no significant differences as tested(P>0.05).The results showed that the research group had significantly reduced incidence of iodine contrast extravasation(7 vs 1,P=0.031),similar incidence of adverse events(11 vs 7,P=0.324),reduced nursing time[(18.50±2.68)minutes vs(13.26±3.00)minutes,P=0.000],fewer venipuncture attempts[(2.21±0.78)times vs(1.49±0.58)times,P=0.000],lower catheter maintenance cost[(1251.79±205.47)China yuan(CNY)vs(1019.25±117.28)CNY,P=0.000],increased intubation success rate(16.67%vs 58.82%,P=0.000),and better imaging quality(85.29%vs 94.12%,P=0.038).CONCLUSION High-pressure-resistant PICCs can lessen the physical burden of diabetic patients during nursing,reduce treatment costs,and improve the efficiency and quality of imaging for diagnosis malignant tumors.
文摘[Objectives]To observe the therapeutic effect of intragastric administration of Jiangtang Shuxin recipe on diabetic heart failure(DHF)in rats and to explore its mechanism.[Methods]Fifty SD rats were randomly divided into five groups,with 10 rats in each group.DHF models were prepared in the low-dose group,high-dose group,Western medicine group,and model group except the control group.Rats in the low-dose and high-dose groups were given 1.0 and 1.5 g/(kg·d)Jiangtang Shuxin recipe suspension by gavage,respectively.Rats in the Western medicine group were given gliquidone and benazepril by gavage for 2 months,and were fed with high-fat diet.Rats in the control group were fed with ordinary diet.Fasting blood glucose(FBG),serum triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),C-reactive protein(CRP),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),creatine kinase isoenzyme(CK-MB),lactate dehydrogenase(LDH),pathological morphology of myocardial tissue,NF-κB p65 protein and IκBαprotein were compared among groups.[Results]Compared with the control group,the levels of FBG,serum TG,LDL-C,CRP,IL-6,TNF-α,CK-MB and LDH increased,while the level of serum HDL-C decreased.The myocardial tissue was seriously damaged,and the expression of NF-κB p65 protein increased,while the expression of IκBαprotein decreased in the other four gruops(all P<0.05).Compared with the model group,the levels of FBG,serum TG,LDL-C,CRP,IL-6,TNF-α,CK-MB and LDH decreased,while the serum HDL-C level increased.The myocardial tissue damage was alleviated,and the expression of NF-κB p65 protein decreased,while the expression of IκBαprotein increased in the low-dose group,high-dose group and Western medicine group(all P<0.05).Compared with the Western medicine group,the levels of FBG,serum TG,LDL-C,CRP,IL-6,TNF-α,CK-MB and LDH decreased,and the level of serum HDL-C increased in the high-dose group(all P<0.05).[Conclusions]Jiangtang Shuxin recipe has a therapeutic effect on DHF in rats,with the best effect in the high-dose group.It can not only alleviate high glucose and high fat state,but also reduce myocardial injury and inflammation,and improve the pathological morphology of myocardial cells.The mechanism may be related to its inhibition of NF-кB signaling pathway.

文摘ACKGROUND The hemoglobin glycation index(HGI)represents the discrepancy between the glucose management indicator(GMI)based on mean blood glucose levels and laboratory values of glycated hemoglobin(HbA1c).The HGI is a promising indicator for identifying individuals with excessive glycosylation,facilitating personalized evaluation and prediction of diabetic complications.However,the factors influencing the HGI in patients with type 1 diabetes(T1D)remain unclear.Autoimmune destruction of pancreaticβcells is central in T1D pathogenesis,yet insulin resistance can also be a feature of patients with T1D and their coexistence is called“double diabetes”(DD).However,knowledge regarding the relationship between DD features and the HGI in T1D is limited.AIM To assess the association between the HGI and DD features in adults with T1D.METHODS A total of 83 patients with T1D were recruited for this cross-sectional study.Laboratory HbA1c and GMI from continuous glucose monitoring data were collected to calculate the HGI.DD features included a family history of type 2 diabetes,overweight/obesity/central adiposity,hypertension,atherogenic dyslipidemia,an abnormal percentage of body fat(PBF)and/or visceral fat area(VFA)and decreased estimated insulin sensitivity.Skin autofluorescence of advanced glycation end products(SAF-AGEs),diabetic complications,and DD features were assessed,and their association with the HGI was analyzed.RESULTS A discrepancy was observed between HbA1c and GMI among patients with T1D and DD.A higher HGI was associated with an increased number of SAF-AGEs and a higher prevalence of diabetic microangiopathy(P=0.030),particularly retinopathy(P=0.031).Patients with three or more DD features exhibited an eight-fold increased risk of having a high HGI,compared with those without DD features(adjusted odds ratio=8.12;95%confidence interval:1.52-43.47).Specifically,an elevated PBF and/or VFA and decreased estimated insulin sensitivity were associated with high HGI.Regression analysis identified estimated insulin sensitivity and VFA as factors independently associated with HGI.CONCLUSION In patients with T1D,DD features are associated with a higher HGI,which represents a trend toward excessive glycosylation and is associated with a higher prevalence of chronic diabetic complications.

文摘Objective:To evaluate the efficacy and safety of traditional Chinese exercises(TCE)in patients with diabetic peripheral neuropathy(DPN)and to recommend best practices for using TCE to improve neurological function,glycemic control,and psychological well-being.Methods:Nine databases were searched from the inception to October 2024.Effect relationships were assessed using meta-analysis with Stata 17,and the methodological quality and certainty of the evidence were evaluated using standard tools.Results:Twelve studies comprising three study designs(nine randomized controlled,one quasi-exper-imental controlled,and two single-arm clinical trials),were identified.Compared with usual care,TCE improved various indicators and enhanced the nerve conduction velocities of the peroneal motor(mean difference[MD]=3.86 m/s,95%confidence interval[CI]:0.38 to 7.34,P=0.03),sural sensory(MD=4.15 m/s,95%CI:0.68 to 7.63,P=0.02),median motor(MD=3.84 m/s,95%CI:2.14 to 5.54,P<.001),and median sensory nerves(MD=6.14 m/s,95%CI:4.54 to 7.74,P<.001).TCE practices also reduced glycosylated hemoglobin level(MD=-0.59%,95%CI:-0.91 to-0.27,P<.001)and fasting blood glucose(standardized mean difference[SMD]=-1.08,95%CI:-1.79 to-0.37,P<.001).The overall quality of evidence was very low.Conclusion:The results indicate that TCE therapy improves certain outcomes in patients with DPN.Although the optimal type,intensity,frequency,and duration of TCE interventions are uncertain,these preliminary findings suggest that TCE should be further studied as a potentially affordable and effective treatment for DPN.

文摘BACKGROUND Achieving optimal glycemic control is a cornerstone of cardiovascular risk reduction in type 2 diabetes(T2D).However,the extent to which multifactorial interventions influence this relationship remains uncertain.AIM To evaluate the association between glycated hemoglobin(HbA1c)target achievement and long-term cardiovascular outcomes in patients receiving standard of care(SoC)or multifactorial intensive therapy(MT).METHODS This post-hoc analysis of the nephropathy in diabetes type 2 cluster-randomized trial included 323 patients with T2D,albuminuria,and retinopathy(SoC:n=139;MT:n=184),who underwent a 4-year intervention phase.Outcomes were major adverse cardiovascular events(MACE)and all-cause mortality.Associations with HbA1c target achievement(≤7%vs>7%)were assessed using Kaplan-Meier curves and shared frailty Cox regression models.RESULTS During a median follow-up of 12.1 years,190 MACEs and 139 deaths occurred.Achievement of the HbA1c target was not associated with reduced mortality in either group.However,a significant reduction in MACEs was observed only among SoC patients achieving HbA1c≤7%(P=0.031),whereas no benefit was seen in the MT group(P=0.645).In multivariable Cox regression models adjusted for cluster effect,in the MT group age[hazard ratio(HR)=1.07,P<0.001]and female sex(HR=0.38,P<0.001)were independent predictors of MACE,while in the SoC group only age(HR=1.04,P=0.009).For all-cause mortality,age(HR=1.11,P<0.001)and blood pressure control(HR=0.55,P=0.041)were significant predictors in the MT group,whereas age(HR=1.06,P=0.002)was independently associated with increased mortality in the SoC group.CONCLUSION In high-risk patients with T2D receiving standard care,achieving an HbA1c≤7%was associated with fewer cardiovascular events only under standard care,but not with reduced mortality.This association was not observed in patients managed with a multifactorial strategy.These findings suggest that the prognostic value of glycemic control depends on the broader treatment context and highlight the central role of comprehensive risk factor management in microvascularcomplicated T2D.

文摘OBJECTIVE： To evaluate the efficacy of α-lipoic acid（ALA） plus epalrestat combination therapy in the treatment of diabetic peripheral neuropathy（DPN）. DATA SOURCES： The electronic databases of Pub Med, Medline, Embase, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Wanfang Database and the Chinese Biomedical Database were used to retrieve relevant studies without language restrictions. The search was conducted from the inception of each database to 7 October 2016. The key terms were（diabetic peripheral neuropathy or diabetic neuropathy or DPN） AND（α-lipoic acid or lipoic acid or thioctic acid） AND epalrestat. DATA SELECTION： All of the eligible studies met the following inclusion criteria：（1） Randomized controlled trials that compared efficacy and safety of epalrestat plus ALA combination therapy versus epalrestat or ALA monotherapy in patients with DPN.（2） The minimum duration of treatment was 2 weeks.（3） The DPN patients were diagnosed using the World Health Organization standardized type 2 diabetes mellitus and DPN criteria.（4） Studies contained at least one measure that could reflect the efficacy of the drug and nerve conduction velocities. Studies in which the control group used epalrestat or ALA combined with other drugs were excluded. Statistical analyses were performed using STATA software for meta-analysis. OUTCOME MEASURES： The primary outcomes were the therapeutic efficacy, median motor nerve conduction velocity（MNCV）, median sensory nerve conduction velocity（SNCV）, peroneal MNCV and peroneal SNCV.RESULTS： Twenty studies with 1894 DPN patients were included, including 864 patients in the ALA plus epalrestat group, 473 in the ALA group and 557 in the epalrestat group. The efficacy of ALA plus epalrestat combination therapy was superior to ALA and epalrestat monotherapies（RR = 1.29, 95% CI： 1.21–1.38; RR = 1.43, 95% CI： 1.34–1.54, respectively）. ALA plus epalrestat combination therapy also significantly improved median MNCV（WMD = 5.41, 95% CI： 2.07–8.75）, median SNCV（WMD = 5.87, 95% CI： 1.52–10.22）, peroneal MNCV（WMD = 5.59, 95% CI： 2.70–8.47） and peroneal SNCV（WMD = 4.57, 95% CI： 2.46–6.68）.CONCLUSION： ALA plus epalrestat combination therapy was superior to ALA and epalrestat monotherapies for clinical efficacy and nerve conduction velocities in patients with DPN.

文摘Increased reactive oxygen species by the activation of NADPH oxidase（NOX） contributes to the development of diabetic complications.Apocynin,a NOX inhibitor,increases sciatic nerve conductance and blood flow in diabetic rats.We investigated potential protective effect of apocynin in rat diabetic neuropathy and its precise mechanism of action at molecular level.Rat models of streptozotocin-induced diabetes were treated with apocynin（30 and 100 mg/kg per day,intragastrically） for 4 weeks.Mechanical hyperalgesia and allodynia were determined weekly using analgesimeter and dynamic plantar aesthesiometer.Western blot analysis and histochemistry/immunohistochemistry were performed in the lumbar spinal cord and sciatic nerve respectively.Streptozotocin injection reduced pain threshold in analgesimeter,but not in aesthesiometer.Apocynin treatment increased pain threshold dose-dependently.Western blot analysis showed an increase in catalase and NOX-p47 phox protein expression in the spinal cord.However,protein expressions of neuronal and inducible nitric oxide synthase（n NOS,i NOS）,superoxide dismutase,glutathion peroxidase,nitrotyrosine,tumor necrosis factor-α,interleukin-6,interleukin-1β,aldose reductase,cyclooxygenase-2 or MAC-1（marker for increased microgliosis） in the spinal cord remained unchanged.Western blot analysis results also demonstrated that apocynin decreased NOX-p47 phox expression at both doses and catalase expression at 100 mg/kg per day.Histochemistry of diabetic sciatic nerve revealed marked degeneration.n NOS and i NOS immunoreactivities were increased,while S-100 immunoreactivity（Schwann cell marker） was decreased in sciatic nerve.Apocynin treatment reversed these changes dose-dependently.In conclusion,decreased pain threshold of diabetic rats was accompanied by increased NOX and catalase expression in the spinal cord and increased degeneration in the sciatic nerve characterized by increased NOS expression and Schwann cell loss.Apocynin treatment attenuates neuropathic pain by decelerating the increased oxidative stress-mediated pathogenesis in diabetic rats.
