The angiotensin II receptor-neprilysin inhibitor LCZ696 attenuates the progression of proteinuria in type 2 diabetic rats

We examined the effects of the angiotensin receptor-neprilysin inhibitor LCZ696 on overt proteinuria and renal injury in type 2 diabetic Otsuka-Long- Evans-Tokushima-Fatty (OLETF) rats. Aged OLETF rats were also treated with either valsartan or valsartan plus hydralazine for comparison. LCZ696 caused greater attenuation of the progression of proteinuria than either valsartan alone or valsartan combined with hydralazine. Reduced glomerular injury and tubulointerstitial fibrosis were also observed in LCZ696-treated rats. Moreover, LCZ696 prevented increases in blood urea nitrogen (BUN) and creatinine levels. These data suggest that LCZ696 elicits a reno-protective effect against type 2 diabetes with overt proteinuria.     

糖尿病足溃疡创面感染患者MMP-2、TIMP-2、Smad3蛋白表达状况及其诊断价值分析

目的探究糖尿病足溃疡创面感染患者的基质金属蛋白酶2(MMP-2)、基质金属蛋白酶2抑制因子(TIMP-2)、Smad3蛋白的表达状况及其诊断价值。方法回顾性分析达州市中心医院于2017年3月至2018年9月收治的45例糖尿病足溃疡患者资料。将伴有溃疡创面感染的25例糖尿病足者作为观察组,其中单一细菌感染16例,混合细菌感染9例;Ⅱ级溃疡11例,Ⅲ级溃疡14例。其余20例未伴有溃疡创面感染的糖尿病足患者作为对照组。对比两组患者的MMP-2、TIMP-2、Smad3蛋白的表达状况,同时对观察组中不同感染类型、不同溃疡类型患者的MMP-2、TIMP-2、Smad3蛋白的表达状况进行比较。结果观察组患者溃疡创面的MMP-2、MMP-2/TIMP-2及Smad3水平均明显高于对照组,TIMP-2水平显著低于对照组差异有统计学意义(P <0.05)。不同感染类型和不同溃疡类型患者的TIMP-2水平比较无显著差异(P>0.05),混合感染患者溃疡创面的MMP-2、MMP-2/TIMP-2和Smad3水平均明显高于单一感染患者;Ⅲ级溃疡患者的MMP-2、MMP-2/TIMP-2和Smad3水平均明显高于Ⅱ级溃疡,差异有统计学意义(P <0.05)。结论糖尿病足溃疡创面感染患者的感染种类以及溃疡程度与MMP-2、TIMP2失衡以及Smad3蛋白异常表达明显相关。观察MMP-2、TIMP-2、Smad3蛋白水平变化对于糖尿病足溃疡创面感染患者的病情评估及其预后判断具有重要价值。     

Redefining diabetic foot disease management service during COVID-19 pandemic

Background & aimsDiabetic Foot Disease (DFD) management had to be redefined during COVID-19. We aim to evaluate the impact of this on diabetic foot care services and the strategies adopted to mitigate them.MethodsWe have performed a comprehensive review of the literature using suitable keywords on the Search engines of PubMed, SCOPUS, Google Scholar and Research Gate in the first two weeks of May 2020. We have reviewed how the diabetic foot service in the hospital and community setting has been affected by the current Coronavirus outbreak.ResultsWe found considerable disruption in diabetic foot service provisions both in the primary care and in the hospital settings. Social distancing and shielding public health guidelines have impacted the delivery of diabetic foot services.ConclusionAs the COVID-19 pandemic spreads worldwide, health care systems are facing the tough challenges in delivering diabetic foot service to patients. Public health guidelines and the risk of virus transmission have resulted in reconfiguration of methods to support and manage diabetic foot patients including remote consultations.     

Application of tele-podiatry in diabetic foot management: A series of illustrative cases

Background and aimsTelemedicine had been proposed as a tool to manage diabetes, but its role in management of diabetic foot ulcer is still evolving. The COVID-19 pandemic and related social restrictions have necessitated the use of telemedicine in the management of diabetic foot disease (tele-podiatry), particularly of patients classified as low-risk.Materials and methodsWe present a report of three cases of varied diabetic foot problems assessed during the present pandemic using different forms of telemedicine for triaging, management of low-risk cases and for follow-up.ResultsTele-podiatry was effective in the management of low-risk subjects with diabetic foot ulcer, and also useful in referral of high-risk subjects for hospital/clinic visit, facilitating proper management. It also helped in the follow-up of the cases.ConclusionTelemedicine is a good screening tool for diagnosing and managing low-risk subjects with diabetic foot problems, and also enables a triaging system for deciding on hospital visits and hospitalization. Telemedicine offers several benefits in the management of diabetic foot disease, although it also has some limitations. Based on our experience during the pandemic, we recommend its judicious use in the triaging of patients of diabetic foot disease and management of low-risk cases. Future innovation in technology and artificial intelligence may help in better tele-podiatry care in the time to come.     

水陆地黄汤联合盐酸贝那普利对气阴两虚夹瘀型糖尿病肾病氧化应激及临床指标的影响

目的:观察水陆地黄汤对气阴两虚夹瘀型糖尿病肾病氧化应激及临床指标的影响。方法:60例气阴两虚夹瘀型糖尿病肾病患者随机分为对照组与联合组,每组30例,对照组给予盐酸贝那普利片10 mg,1次/d,联合组在对照组基础上加服水陆地黄汤,1剂/d。治疗12周后观察两组氧化应激指标:谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)、丙二醛(MDA)及临床指标:空腹血糖(FPG)、餐后2 h血糖(2 hPG)、糖化血红蛋白(HbA1c)、尿微量白蛋白(mALB)、24 h尿蛋白定量(24 hU-PQ)、肾小球滤过率(eGFR)的变化及临床症状的改善。结果:联合组治疗总有效率为90.0%,与对照组56.7%比较,差异有统计学意义(P<0.05);治疗后联合组MDA较治疗前均降低(P<0.05),SOD、GSH-Px均高于治疗前(P<0.05),与对照组比较,差异有统计学意义(P<0.05);联合组FPG、2 hPG、HbA1c、mALB、24 hU-PQ、eGFR较治疗前均降低(P<0.01)。结论:水陆地黄汤联合盐酸贝那普利可改善气阴两虚夹瘀型糖尿病肾病氧化应激状态,明显缓解临床症状,延缓病程进展。
