Even one the same pathological type of various kinds of refractory nephrotic syndrome has great dif-ferent pathogenesis. It is more reported in recent years that new nephrotic medications(such as Ofatumumab and Eculi-zumab)or novel utilized old medications(such as CoQ10,galactose and retinoic acid)used in other diseases were re-searched and developed based on the mechanisms of nephrotic syndrome,or new mechanisms were contrarily discovered when new medications used in other diseases were effectively used in refractory nephrotic syndrome. Here,the novel medications which were successfully used in clinic patients with refractory nephrotic syndrome,or laboratory proteinuric animal models,or the old medications with new and effective actions were introduced. Their mechanisms of drug actions were also briefly described. It is hoped that these information has practical value for the medication selection by clinical nephrologist and for the collision of research idea inspiration by investigators in nephropathy research area.

It is widely accepted that diabetes is intimately linked to diet. The latest researches showed that diet-microbiota interactions acted as moderators of human diabetes. Gluten-free diet and hydrolyzed protein decreased the incidence of type 1 diabetes mellitus (T1DM)by the mechanism of changes in gut microbiota and immune micro-environment. Consuming more dairy products decreased the incidence of type 2 diabetes mellitus (T2DM). High fat diet can induce insulin resistance (IR),thus increasing the incidence of T2DM. Parental dietary affected on offspring diabetes by the epigenetic mechanism. Low carbohydrate diet,dietary fiber and legumes were effective to the treatment of diabetes. Prediction of postprandial glucose level and treatment based on gut microbiota contributed to control the glucose of diabetic patients. An in-depth understanding of these mechanisms provides new ideas for the individualized and precise treatment of diabetes.

Objective To investigate the changes of intestinal blood flow and motility and their effects on intestinal mucosa barrier in rats with acute cerebral ischemia. Methods 64 male Wistar rats were assigned randomly into cerebral ischemia group (n=32) and control group (n=32).The two groups were divided into four subgroups according to timepoints of 6 h,12 h,24 h and 48 h after operation (8 rats for each subgroup).The intestinal mucosa blood flow,intestinal transmit index and endotoxin level in porlal vein were detected.The displacement ratio of E.coli was marked and counted with fluorescent microscope in tissue homogenate from organs. Results The intestinal blood flow in cerebral ischemia group at 6 h,12 h,24 h and 48 h after operation [(34.5±3.2)PU,(22.7±1.9)PU,(26.2±4.3) PU and (30.5± 4.1) PU] were significantly lower than control group[(46.8 ±5.4) PU,(50.1±3.6) PU,(45.4±4.1) PU and (48.7±7.3) PU] (t=2.650,2.875,2.639 and 2.507,all P＜0.05).The intestinal transmit index in cerebral ischemia group at 6 h,12 h,24 h and 48h after operation[(0.59±0.07),(0.48±0.06),(0.50±0.08)and (0.57±0.04)] were decreaesd as compared with control group [(0.73±0.04),(0.75=0.02),(0.74±0.06) and (0.76±0.03)] (t=2.409,2.758,2.649 and 2.807,all P＜0.05). The levels of endotoxin in cerebral ischemia group started to increase at 6 h and arrived to peak at 24 h,and the levels at four timepoints were (0.382 ± 0.014) Eu/ml, (0.466 ± 0.018) Eu/ml,(0.478 ± 0.029) Eu/ml and (0.412±0.036)Eu/ml,respectively,that were higher than those in control group[(0.102±0.007)Eu/ml,(0.114±0.021)Eu/ml,(0.112±0.018)Eu/ml and (0.108±0.011)Eu/ml] (all P＜0.05).The total E.coli detection rates in multiple organs in cerebral ischemia group (11.4％,18.8 ％,25.0％and 12.5％) were higher than in control group (2.1％,4.2％,2.1％ and 0.0％) at four rime points (all P＜0.05). The level of endotoxin was negatively related with the intestinal blood flow and intestinal transmit index( r =- 0.861 and - 0.796,both P＜ 0.05). Conclusions The higher intestinal mucosa blood flow and intestinal motility play important roles in the increase of intestinal mucosa permeability at early stage after acute cerebral ischemia.

Six compounds were isolated from the whole herb of Phyllanthus urinaria L.

Objective To explore the effect of subcutaneous composite flaps by crossed filling and supporting within areola combined with continuous distraction on moderate and severe inverted nipple.Methods 33 patients with 59 moderate and severe inverted nipples were involved in this study.The bilateral subcutaneous triangular composite tissue flaps pedicled with the base of the nipple were harvested within areola,the two triangular composite tissue flaps were revolved and advanced either horizontally to the opposite pedicle through the tunnel beneath the nipple and fixed as supporting.After the operation,the continuous distraction of the nipple lasted for two to four weeks,clinical effect and complications were analyzed.Results None of these 59 nipples appeared blood circulation disorder after operation.Postoperative follow-up for 6 months to 3 years showed that 54 inverted nipples were corrected completely without complications,such as nipple and areola necrosis,and there were no recurrence.The patients and doctors were satisfied with the appearance of the nipples.Conclusions Correcting the moderate and severe inverted nipple with subcutaneous composite flaps by crossed filling and supporting within areola combined with continuous distraction is simple,microinvasive,effective,and the incision scar is invisible,and it therefore is an ideal method for correcting the inverted nipple.

Objective To investigate the retinoic acid incubation effect on proliferation of U251 cell line and effect on MAPK signal pathway. Methods ATRA solution of different concentration on the U25 1 glioma cells were incubated,the influence of ATRA on the proliferation of U25 1 cells were detected,and the proteins of MKPs and MAPK signaling pathways were detected by qRT-PCR and Western blot.Using Graph Prism 5 software for quantitative analysis of experimental results.Results Compared with control group,ATRA could effectively inhibit the proliferation of U25 1 glioma cells, in a concentration dependent manner.QRT-PCR results showed that,different concentrations of ATRA after incubation for 48 hours,the expression of MKPs mRNA changed,but the changes of MKP-5 and expression of 67LR was different,explained the main differences between the two methods of the MAPK signaling pathway was the regulation of MKP-5.Western blot results showed that the ATRA,after 48 hours of incubation,the protein MAPK pathway had changed in phosphorylation, which showed that ATRA protein in the MAPK signaling pathway through control of the degree of phosphorylation on U25 1 cell line regulation.Conclusion Retinoic acid and retinoic acid receptor play its physiological effects and regulate human glioma cell line U25 1 proliferation through different combination.Retinoic acid could not only reduce the expression of phosphorylated ERK1/2 to inhibit tumor proliferation,but also regulate three kinds of protein phosphorylation,therefore its mechanism will be more complex,at the same time that the MAPK signaling pathway plays a crucial role in tumor proliferation process.

The acetylation status of histones and non-histone proteins regulate chromatin remodeling and gene transcription. Histone deacetylase inhibitors (HDACi), a promising therapeutic approach to cancer, are characteristic of causing accumulation of acetylated histones and other transcriptional regulators. Recent studies demonstrate that HDACi is able to arrest the cell cycle in G1 and/or G2 phase, and to induce apoptosis in a variety form of transformed cells with little toxicity to normal cells. However, the exact antitumor mechanisms of HDACi are still unclear. This review provides an update on the current knowledge of HDACi with a focus on HDACi-regulated cell growth arrest and apoptosis.

Aim To examine the in vivo effect of the antisense or/and decoy oligonucleotide of NF-?B on vessel proliferation and balloon-injured monocytes chemotactic protein-1(MCP-1) and extracellular signal regulated kinase in the carotid artery of rats.Methods Sprague-Dawley rats underwent balloon-dilation injury of the left carotid artery.The rats were divided into 7 groups(n=18) and each group were further divided into 6 sub-groups for study at 6 time points(1,3,5,7,14 days,n=3).Uninjured artery of the same rat was used as the control.Results In model group,sense group and scramble group,intima/media ratio increased after 5 days and reached the maximum after 14 days;intima/media ratio in antisense group,decoy group,antisense plus decoy group decreased significantly(P
