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.

Highly sensitized patients experience an increased number of rejection episodes and have poorer graft survival rates; hence, sensitization is a significant barrier to both access to and the success of organ transplantation. This study reports our experience in kidney transplantation in highly sensitized patients. Fourteen patients with sensitization or high levels of panel-reactive antibodies (PRA) were studied. All patients were desensitized with pre-transplant intravenous immunoglobulin (IVIG)/plasmapheresis (PP) with or without rituximab and thymoglobulin induction therapy, combined with a Prograf/MMF/Pred immunosuppressive regimen. Of 14 patients, 10 showed good graft functions without acute rejection (AR) episodes. Acute cellular rejection in two patients was reversed by methylprednisolone. Two patients underwent antibody-mediated rejection; one was treated with PP/IVIG successfully, whereas the other lost graft functions due to the de novoproduction of donor-specific antibodies (DSA). Graft functions were stable, and there were no AR episodes in other patients. Conclusively, desensitization using PP/IVIG with or without rituximab increases the likelihood of successful live-donor kidney transplantation in sensitized recipients.
Mechanisms of “kidney governing bones” theory in traditional Chinese medicine

Studies conducted by our group on the mechanism of “kidney governing bones” theory in traditional Chinese medicine (TCM) are reviewed in this paper. Conclusions can be summarized as follows. (1) Neuroendocrine-immune network (NIN)-osteoclast regulatory pathway OPG-RANKL-RANK is one of the mechanisms of “kidney governing bones.” Although kidney-reinforcing therapy is regarded as one of the holistic regulatory mechanisms of the body, characteristic holistic regulation in TCM can be reflected through nonselective regulation of the NIN during kidney reinforcement therapy, which can be used to treat osteoporosis through microadjustments in the microenvironment of the bone marrow. (2) Marrow exhaustion in TCM, which is the state wherein lipocytes in the bone marrow increase whereas other cells decrease, serves as the pathogenesis of osteoporosis brought about by failure of the “kidney governing bones.” (3) The kidney in TCM can be regarded as a complex system comprising multiple functional units in the body, including the unit “governing bones.” Kidney deficiency refers to a deficiency in only one or more units of the kidney system and not the whole system itself, which explains the kidney-reinforcing effect of many herbs; some herbs can treat osteoporosis, but some cannot. Although both classified as kidney-reinforcing agents, the former can resolve failure of the “kidney governing bones” unit while the latter regulates the failure of other units in the kidney system. Despite the current understanding on “kidney governing bones” theory, the mechanism of “kidney governing bones” remains complicated and unresolved. Thus, further studies in this area are warranted.

The risk factors, especially laboratory indicators, of prognosis after acute kidney injury (AKI) remain unclear. We conducted a retrospective survey of Chinese People’s Liberation Army General Hospital from January 1, 2012 to December 31, 2012 according to the AKI diagnosis standard issued by Kidney Disease Improving Global Outcomes. The epidemiological features and factors influencing hospital mortality and renal function recovery were evaluated through logistic regression analysis. Among 77 662 cases of hospitalized patients, 1387 suffered from AKI. The incidence rate and mortality of AKI were 1.79% and 14.56%, respectively. Multivariate logistic regression analysis revealed that high AKI stage, age greater than 80 years, neoplastic disease, low cardiac output, increased white blood cell count, and decreased platelet count and serum albumin levels were the risk factors affecting the mortality of AKI patients. Conversely, body mass index between 28 and 34.9 was a protective factor. Increased AKI stage, tumor disease, post-cardiopulmonary resuscitation, and RRT were the risk factors of renal function recovery upon discharge. In addition to traditional risk factors, white blood cell count, platelet count, albumin, and BMI were the predictors of the mortality of AKI patients. No laboratory indicators were found to be the risk factors of renal function recovery in AKI patients.

The purpose of this study is to characterize a meta-signature of differentially expressed mRNA in chronic kidney disease (CKD) to predict putative microRNA (miRNA) in CKD–mineral bone disorder (CKD–MBD) and confirm the changes in these genes and miRNA expression under uremic conditions by using a cell culture system. PubMed searches using MeSH terms and keywords related to CKD, uremia, and mRNA arrays were conducted. Through a computational analysis, a meta-signature that characterizes the significant intersection of differentially expressed mRNA and expected miRNAs associated with CKD–MBD was determined. Additionally, changes in gene and miRNA expressions under uremic conditions were confirmed with human Saos-2 osteoblast-like cells. A statistically significant mRNA meta-signature of upregulated and downregulated mRNA levels was identified. Furthermore, miRNA expression profiles were inferred, and computational analyses were performed with the imputed microRNA regulation based on weighted ranked expression and putative microRNA targets (IMRE) method to identify miRNAs associated with CKD occurrence. TLR4 and miR-146b levels were significantly associated with CKD–MBD. TLR4 levels were significantly downregulated, whereas pri-miR-146b and miR-146b were upregulated in the presence of uremic toxins in human Saos-2 osteoblast-like cells. Differentially expressed miRNAs associated with CKD-MBD were identified through a computational analysis, and changes in gene and miRNA expressions were confirmed with an in vitro cell culture system.

由于肾衰竭发病率升高的速度远超治疗方法进展的速度,因而对这种疾病的新的治疗方法的需求也以前所未有的速度不断增加。目前的治疗受制于可供应的活器官,而世界范围内均缺乏这种器官。这些治疗模式还需要大量的基础结构,这也极大地限制了大多数国家的患者获得医疗服务的机会。通过肾脏组织工程方法有望开发出替代的解决方案,解决目前治疗中仍存在的许多不足之处。尽管在生物制造和全器官组织工程方面已经取得了许多进展——主要是在过去的10 年中取得的,但仍然存在许多挑战。当前组织工程方法进展中的一个主要障碍是如何对已形成的工程化组织构建体实施成功的血管化。本文主要涉及近年来解决血管问题取得的进展,包括脉管系统的生物制造、通过脱细胞和再细胞化方法实施全器官工程、微尺度器官形成,以及在肾脏组织工程背景下使用类器官取得血管化。本文还着重探讨了在制定成功的临床转化策略中仍然存在的具体问题。

Epithelial-to-mesenchymal transition in cancer: complexity and opportunities

The cell-biological program termed the epithelial-to-mesenchymal transition (EMT) plays an important role in both development and cancer progression. Depending on the contextual signals and intracellular gene circuits of a particular cell, this program can drive fully epithelial cells to enter into a series of phenotypic states arrayed along the epithelial-mesenchymal phenotypic axis. These cell states display distinctive cellular characteristics, including stemness, invasiveness, drug-resistance and the ability to form metastases at distant organs, and thereby contribute to cancer metastasis and relapse. Currently we still lack a coherent overview of the molecular and biochemical mechanisms inducing cells to enter various states along the epithelial-mesenchymal phenotypic spectrum. An improved understanding of the dynamic and plastic nature of the EMT program has the potential to yield novel therapies targeting this cellular program that may aid in the management of high-grade malignancies.
