Kidney damage is common in patients with diabetes mellitus (DM). However, whether the type of kidney damage can be reliably diagnosed using clinical data alone remains unclear. Predictive factors for diabetic nephropathy (DN) outcomes are also poorly understood. In this study, the clinical manifestations of 111 cases of biopsy-proven DN were described, and the clinical and pathological parameters of patients with different DN outcomes were compared. Results showed that long DM duration (>10 years in 32.4% of patients), severe proteinuria (62.2%), and renal dysfunction (estimated glomerular filtration rate [eGFR]<60 mL/(min·1.73 m2)) (52.3%) did not accurately indicate whether the condition of these patients progressed to DN. Hematuria (48.6%) failed to specify either DN or nondiabetic renal disease. Diabetic retinopathy (78.4%) was a crucial complication in patients with DN. Kaplan–Meier analysis revealed that the renal survival of 53 patients who were diagnosed with DN and were followed up was not significantly associated with glomerular classification (P>0.05). Cox’s regression analysis demonstrated that renal survival time was significantly influenced by sex (b= 1.394, P= 0.038), hematuria (b= 0.036, P= 0.029), and eGFR (b= −0.039, P= 0.002) but was not significantly affected by age, 24 h urinary protein excretion, or glomerular classification (P>0.05). In conclusion, the clinical characteristics of DN vary, and renal biopsy is necessary to determine renal damage patterns. Sex, hematuria, and the eGFR may affect DN outcomes, whereas the glomerular classification may not.

由于心脏持续地收缩和舒张，需要大量的能量，其中脂肪酸（FA）是其三磷酸腺苷（ATP）的主要来源。但是，心脏无法制造这种底物，而是从多种来源获得脂肪酸，包括通过脂蛋白脂肪酶（LPL）的作用。脂蛋白脂肪酶在心肌细胞中产生，随后分泌到质膜上的硫酸乙酰肝素蛋白聚糖（HSPG）结合位点。然后为了将脂蛋白脂肪酶转移到内皮细胞管腔，糖基磷脂酰肌醇锚定的高密度脂蛋白结合蛋白1（GPIHBP1）与间质性脂蛋白脂肪酶结合，并将其转移到血管管腔，在那里脂蛋白脂肪酶可将循环中的甘油三酯分解为脂肪酸。内源性-β-葡萄糖醛酸酶乙酰肝素酶（Hpa）的独特之处在于，它是唯一已知的哺乳动物酶，可以裂解硫酸乙酰肝素，从而促进上述脂蛋白脂肪酶从心肌细胞HSPG中释放。在糖尿病中，一直认为心脏产生能量方式的改变是导致糖尿病性心肌病（DCM）的原因。糖尿病发展到中度后，随着葡萄糖利用率的降低，由于Hpa 作用的增强，心脏血管腔内的脂蛋白脂肪酶活性得到增强。虽然这种适应可能有助于补偿心脏对葡萄糖的利用不足，但从长期来看，它是具有毒性的，因为有害的脂质代谢物积聚，以及脂肪酸氧化增强和因此造成的氧化应激，最终导致细胞死亡。这与一种心脏保护生长因子——血管内皮生长因子B（VEGFB）的丧失同时发生。本文探讨了乙酰肝素酶、脂蛋白脂肪酶和血管内皮生长因子B之间的相互联系及其在糖尿病性心肌病中的潜在影响。鉴于缺乏基于机制的DCM治疗，了解这种心肌病的病理，以及脂蛋白脂肪酶的作用，将有助于我们推进其临床治疗。

Diabetic kidney disease (DKD) is one of the primary causes of end-stage renal disease (ESRD). Early diagnosis is very important in preventing the development of DKD. Urinary albumin excretion rate (UAER) and glomerular filtration rate (GFR) are widely accepted as criteria for the diagnosis and clinical grading of DKD, and microalbuminuria has been recommended as the first clinical sign of DKD. The natural history of DKD has been divided into three stages: normoalbuminuria, microalbuminuria, and macroalbuminuria. However, this clinical paradigm has been questioned recently, as studies have shown that a portion of diabetes mellitus (DM) patients with normoalbuminuria have progressive renal insufficiency, referred to as normoalbuminuric diabetic kidney disease (NADKD) or nonalbuminuric diabetic nephropathy. Epidemiologic research has demonstrated that normoalbuminuric diabetic kidney disease is common, and the large number of NADKD patients suggests that the traditional paradigm needs to be shifted. Currently, the pathogenesis of NADKD remains unclear, but many clinical studies have identified some clinical and pathological features of NADKD. In addition, the long-term outcomes of NADKD patients remain controversial. In this article, we reviewed the latest studies addressing the pathogenesis, pathology, treatment and prevention of NADKD.

Diabetic nephropathy (DN) is one of the most common microvascular complications in diabetes mellitus patients and is characterized by thickened glomerular basement membrane, increased extracellular matrix formation, and podocyte loss. These phenomena lead to proteinuria and altered glomerular filtration rate, that is, the rate initially increases but progressively decreases. DN has become the leading cause of end-stage renal disease. Its prevalence shows a rapid growth trend and causes heavy social and economic burden in many countries. However, this disease is multifactorial, and its mechanism is poorly understood due to the complex pathogenesis of DN. In this review, we highlight the new molecular insights about the pathogenesis of DN from the aspects of immune inflammation response, epithelial–mesenchymal transition, apoptosis and mitochondrial damage, epigenetics, and podocyte–endothelial communication. This work offers groundwork for understanding the initiation and progression of DN, as well as provides ideas for developing new prevention and treatment measures.

Familial amyloid cardiomyopathy is a challenging condition that mimics many other diseases, particularly in patients with pronounced neurological presentations and unexplained or equivocal cardiac abnormalities. In this case, a 57-year-old man was admitted for outpatient cardiological evaluation of progressive right heart failure and limb paraesthesias. The patient presented with hypertension, chronic Guillain-Barre syndrome, and sick sinus syndrome. Transthoracic echocardiograms showed a thickened ventricular wall and enlarged atrium. Tissue Doppler showed a restrictive filling pattern. Transthyretin (TTR)-associated amyloidosis, which was revealed by abdominal fat-pad biopsy and DNA analysis, explained the concurrence of independent pathological features, including neuropathy and cardiac involvement. Genetic testing identified a G>T mutation in exon 4 of the transthyretin (TTR) gene. This mutation resulted in the alanine-to-serine substitution at amino acid position 117. Moreover, genetic testing confirmed that the patient’s asymptomatic son carried the same amyloidogenic TTR mutation. Given these findings, the diagnosis of familial amyloid cardiomyopathy, which was misdiagnosed as chronic Guillain-Barre syndrome, was proposed.

Systemic inflammatory response following myocardial ischemia-reperfusion injury (IRI) to a specific organ may cause injuries. Ischemic post-conditioning (IPostC) has emerged as a promising method for myocardial protection against IRI both in experimental and in clinical settings. Enhancement of endogenous nitric oxide (NO) is one of the major mechanisms by which IPostC confers cardioprotection. However, the sensitivity of the diabetic heart to IPostC is impaired and the underlying mechanism is unknown. Adiponectin (APN) is an adipocyte-derived plasma protein with anti-diabetic and anti-inflammatory properties. Plasma levels of APN are decreased in obese subjects and in patients with type 2 diabetes. APN supplementation has been shown to increase NO production and attenuate myocardial IRI in normal (non-diabetic) animals. However, the effect of APN on myocardial injury in diabetic subjects, especially its potential in restoring the sensitivity of the diabetic heart to IPostC has not been investigated. In the current paper, we discussed the possible reasons why the myocardium of diabetic subjects loses sensitivity to IPostC and also highlighted the potential effectiveness and mechanism of APN in restoring IPostC cardioprotection in diabetes. This review proposes to conduct studies that may facilitate the development of novel and optimal therapies to enhance cardioprotection in patients with severe diseases such as diabetes.

Zinc (Zn) is an essential mineral that is required for various cellular functions. Zn dyshomeostasis always is related to certain disorders such as metabolic syndrome, diabetes and diabetic complications. The associations of Zn with metabolic syndrome, diabetes and diabetic complications, thus, stem from the multiple roles of Zn: (1) a constructive component of many important enzymes or proteins, (2) a requirement for insulin storage and secretion, (3) a direct or indirect antioxidant action, and (4) an insulin-like action. However, whether there is a clear cause-and-effect relationship of Zn with metabolic syndrome, diabetes, or diabetic complications remains unclear. In fact, it is known that Zn deficiency is a common phenomenon in diabetic patients. Chronic low intake of Zn was associated with the increased risk of diabetes and diabetes also impairs Zn metabolism. Theoretically Zn supplementation should prevent the metabolic syndrome, diabetes, and diabetic complications; however, limited available data are not always supportive of the above notion. Therefore, this review has tried to summarize these pieces of available information, possible mechanisms by which Zn prevents the metabolic syndrome, diabetes, and diabetic complications. In the final part, what are the current issues for Zn supplementation were also discussed.

The association between dyslipidemia and elevated fasting glucose in type 2 diabetes is well known. In non-diabetes, whether this association still exists, and whether dyslipidemia is an independent risk factor for high fasting plasma glucose (FPG) levels are not clear. This cross-sectional study recruited 3460 non-diabetic Chinese subjects (1027 men, and 2433 women, aged 35–75 years old) who participated in a health survey. Men and women were classified into tertiles by levels of plasma lipids respectively. In women, the prevalence of impaired fasting glucose (IFG) was decreased with increased HDL-C. A stepwise increase in HDL-C was associated with decreasing FPG levels (lowest tertiles, FPG: 5.376±0.018; middle tertiles, 5.324±0.018; highest tertiles, 5.276±0.018 mmol/L; P=0.001). Reversely, FPG levels increased from lowest tertiles to highest tertiles of LDL-C, TC, and TG. we found that women in the first tertile with lower HDL-C level had a 1.75-fold increase in risk of IFG compared with non-diabetic women in the third tertile with higher HDL-C level (OR: 1.75; 95% CI: 1.20--2.56). In men, no significant association was found. We took age, BMI, waist/hip ratio, education, smoking, alcohol drinking, and physical exercise as adjusted variables. In Chinese non-diabetic women, dyslipidemia is independently associated with high levels of FPG; TG, HDL-C, and LDL-C are predictors of IFG independent of BMI and waist/hip ratio.
