Animal models with kidney disease are generally divided into two types. One belongs to the models which imitate human kidney disease by the artificial operations, such as anti-glomerular basement membrane antibody nephritis, Heymann nephritis, anti-Thyl. 1 antibody nephritis, BSA nephritis and puromycin nephropathy. The other one pertains to the models which make themselves kidney disease, and appear the pathological characteristics naturally as like as human, such as HIGA mice with IgA nephropathy and NZB/WF1 and MRL/1pr mice with lupus nephritis. In addition,the transgenic animal models with kidney disease can also be established by the modern molecular biologic techniques including gene knockout and siRNA transfection. As for the studies related with kidney disease in pharmacodynamics and pharmacology of Chinese herbal medicine (CHM), it is important to understand deeply the features of each animal model with kidney disease, and select accurately the proper models according to the different experimental objectives, and then, build the special models provided with the combination of disease with syndrome in traditional Chinese medicine (TCM). Therefore,it is the developmental direction for the further study to establish animal models with kidney disease, which should possess the characteristics of syndrome in TCM.

OBJECTIVETo investigate the types of lipid disorder and its relationship with macrovascular diseases and insulin resistance in Chinese diabetic patients.
METHODS2,430 diabetic patients finished the diabetes complications assessment and were surveyed on their blood lipids, insulin level and macrovascular diseases. The insulin resistance (HOMA-IR) was calculated based on HOMA model.
RESULTSPrevalence of lipids disorder was as high as 63.8% in this group, including 23.9% with both hypercholesterolemia and hypertriglyceridemia (HY-C-T), 16.1% with hypercholesterolemia only (HY-C), 15.0% with hypertriglyceridemia only (HY-T), 5.5% with lower HDL level (L-HDL), 3.3% with hypercholesterolemia, hypertriglyceridemia and lower HDL level together. Compared with the patients with normal lipid level (control group), no duration differences existed among these groups. There were more female patients in HY-C and HY-C-T groups. BMI and WHR were higher in all groups with lipid disorder except in HY-C group. Macrovascular diseases were more common in HY-C-T patients than in control group (33.6% vs 24.0%, P < 0.001). Average blood pressure and the prevalence of hypertension were significantly higher in HY-C-T, HY-C, HY-T groups than in control group (139/79, 138/76, 134/77 vs. 132/75 mmHg; 53.2%, 50.1%, 46.2% vs. 39.2%). Fasting insulin level was significantly higher in HY-C-T and HY-C-T-L-LDL groups than in controls. Insulin resistance was more severe in all patients with lipid disorder except in L-HDL group, particularly in the HY-C-T-L-HDL group.
CONCLUSIONS(1) BMI, WHR increased significantly with the severity of lipid disorder. (2) Nearly two thirds of Chinese diabetic patients have lipid disorder, which is the strong risk factor of macrovascular diseases and aggravates insulin resistance. (3) There was severe insulin resistance in patients with hypertriglyceridemia or with hypertriglyceridemia plus other lipid disorder.

Diabetes mellitus (DM) has grown up to be an important issue of global public health because of its high incidence rate. Diabetic kidney disease (DKD) is the main cause of end-stage kidney disease (ESKD). Therefore, early diagnosis and timely prevention and treatment of DKD are essential for the progress of DM. The clinical diagnosis and staging of DKD are mostly based on the urinary albumin excretion rate (UAER) and estimated glomerular filtration rate (eGFR). However, clinically, DKD patients show normoalbuminuric diabetic kidney disease (NADKD) instead of clinical proteinuria. The old NADKD concept is no longer suitable and should be updated accordingly with the redefinition of normal proteinuria by NKF/FDA (National Kidney Foundation/Food and Drug Administration). Based on the relevant guidelines of DM and chronic kidney disease (CKD) and combined with the current situation of clinical research, the review described NADKD from the aspects of epidemiology, pathological mechanism, disease diagnosis, clinical characteristics and biomarkers, to arouse the new understanding of NADKD in the medical profession and pay attention to it.

OBJECTIVE:
Small ubiquitin-related modifiers (SUMOs) are a group of post-translational modification proteins extensively expressed in eukaryotes. Abnormal SUMOylation can lead to the development of various diseases. This article summarizes the progress on research of the role of SUMOs in various types of kidney diseases to further increase the understanding of the regulatory functions of SUMOylation in the pathogenesis of kidney diseases.
DATA SOURCES:
This review was based on articles published in the PubMed databases up to January 2018, using the keywords including "SUMOs," "SUMOylation," and "kidney diseases."
STUDY SELECTION:
Original articles and critical reviews about SUMOs and kidney disease were selected for this review. A total of 50 studies were in English.
RESULTS:
SUMO participates in the activation of NF-κB inflammatory signaling pathway, playing a central regulatory role in the inflammation and progression of DN, and the secretion of various chemokines in AKI. SUMO involves in the regulation of TG2 and Nrf2 antioxidant stress, affecting renal tubular injury in AKI. SUMO affects the MAPK/ERK pathway, regulating intracellular signal transduction, modulating the transcription and expression of effector molecules in DN. SUMO contributes to the TGF-β/Smad pathway, leading to fibrosis of the kidney. The conjugate combination of SUMO and p53 regulates cell proliferation and apoptosis, and participates in the regulation of tumorigenesis. In addition, SUMOylation of MITF modulates renal tumors secondary to melanoma, Similarly, SUMOylation of tumor suppressor gene VHL regulates the occurrence of renal cell carcinoma in VHL syndrome.
CONCLUSIONS
Tissue injury, inflammatory responses, fibrosis, apoptosis, and tumor proliferation in kidney diseases all involve SUMOs. Further research of the substrate SUMOylation and regulatory mechanisms of SUMO in kidney diseases will improve and develop new treatment measures and strategies targeting kidney diseases.

OBJECTIVETo explore the podocyte injury in patients with diabetic nephropathy (DN) and analyze its relationship with glucose regulated protein 78 (GRP78) and proteinuria.
METHODSThe clinical data of 48 patients diagnosed as DN by renal biopsy were reviewed. All patients were divided into two groups according to proteinuria (>3.5 g/d, n=31 and 3.5 g/d, n=17). The density of podocytes was illustrated by immunohistochemistry staining of Wilms tumor-1 (WT-1), and the immunofluorescence double-staining results of synaptopodin and GRP78 in podocytes were detected.
RESULTSThe podocyte dentistry of urine protein > 3.5 g/d group was significantly lower than that of urine protein>3.5 g/d group urine protein<3.5 g/d group(P=0.003), and it was negatively correlated with proteinuria (P=0.005). The expressions of synaptopodin and GRP78 in podocytes were also negatively correlated with proteinuria (P=0.004 and P=0.001).
CONCLUSIONThe podocyte injury is aggravated with increased proteinuria in DN patients, along with the decrease of the adaptive ability of endoplasmic reticulum to stress.

BACKGROUNDPrevious studies suggested that zinc level was related to a certain diabetic microvascular complication. However, the relationship between zinc level and all the microvascular complications in type 2 diabetic patients remains unknown. The purpose of this study was to analyze the relationship between zinc level and each diabetic microvascular complication and identify the features related to low serum zinc level.
METHODSWe included the hospitalized patients with type 2 diabetes (T2D) at our department from May 30, 2013 to March 31, 2014. We initially compared the serum zinc levels between patients with specific microvascular complications and those without. We then analyzed the association between zinc level and each microvascular complication. Furthermore, we identified the unique features of patients with high and low serum zinc levels and analyzed the risk factors related to low zinc level.
RESULTSThe 412 patients included 271 with microvascular complications and 141 without any microvascular complications. Serum zinc level was significantly lower in patients with diabetic retinopathy (P < 0.001), diabetic nephropathy (DN, P < 0.001), or diabetic peripheral neuropathy (P = 0.002) compared with patients without that specific complication. Lower zinc level was an independent risk factor for DN (odds ratio = 0.869, 95% confidence interval = 0.765-0.987, P < 0.05). The subjects with lower serum zinc level had manifested a longer duration of diabetes, higher level of hemoglobin A1c, higher prevalence of hypertension and microvascular complications, and lower fasting and 2-h C-peptide levels.
CONCLUSIONSLower serum zinc level in T2D patients was related to higher prevalence of diabetic microvascular complications, and represented as an independent risk factor for DN. Patients with lower zinc level were more likely to have a longer duration of diabetes, poorer glucose control, and worse β-cell function.
