In recent years, microRNAs (miRNAs) have been found to be one of the key factors of post transcriptional gene regulation, which are involved in occurrence and development of many diseases. Peritoneal dialysis (PD) has become an effective alternative treatment approaches for patients with end stage renal disease (ESRD). Peritoneal fibrosis is one of the most important factors leading patients to withdraw from long-term PD, hence restricts the application and development of PD. MicroRNAs are closely related to the development of peritoneal fibrosis. This article reviews the role of miRNAs in the pathogenesis and treatment of peritoneal fibrosis.

Objective In this study, we explored the mechanism of anti-bone resorption of RGD-insulin using osteoclast-like cells (OLCs) from giant cell tumor of bone as an in vitro model. Methods The function of bone resorption was observed and the staining for tartrate-resistant acid phosphatase (TRAPase) was identified. The carbonic anhydrase Ⅱ (CAⅡ) gene expression, apoptosis and the adhesion of OLC that treated by RGD-insulin and echistatin were determined by in situ hybridization, TUNEL staining and adhesion test, respectively. Results OLCs were TRAP positive and had bone resorptive function. After OLCs were treated with 10 -5, 10 -6, 10 -7mol/L RGD-insulin and echistatin respectively, the numbers of TRAP-positive multinucleated cells were (179?3), (238?11), (351?10) per well that treated with echistatin and (229?20), (222?21), (265?17) per well that treat with RGD-insulin.The expression of CAⅡ mRNA decreased, the number of OLCs apoptosis increased in a dose-dependent manner (P

OBJECTIVE: To study the in vitro anti-tumor activity of tungstophosphate compound(K6[P2W18O62]?14H2O) with Dawson structure.METHODS: MCF-7 cells were treated with different concentration of K6[P2W18O62]?14H2O,then its IC50 was measured by MTT assay;flow cytometry was applied to analyze cell cycle and apoptosis by computing the ratio of MCF-7 cells in different phase and its apoptotic ratio.Cell growth and viability were measured by trypan blue staining and cell counting by computing the ratio of living cells.The synergetic anti-tumor activity of tungstophosphate compound(K6[P2W18O62]?14H2O) and pharmorubicin was studied.RESULTS: K6[P2W18O62]?14H2O inhibited MCF-7 cell proliferation with IC50 of(33.7?3.2) ?mol?L-1,it reduced the proportions of MCF-7 cells at S phase and G1 phase,with the apoptotic rate at 3.7%～29.2% within 48 h.The percentage of living cells was 95.37%～76.78% at 48 h.As compared with pharmorubicin alone,the addition of K6[P2W18O62]?14H2O to pharmorubicin showed a significantly higher inhibitory action on proliferation of MCF-7 cells(P

Objective To investigate immunoadsorption in the prevention of hyperacute rejection in highly sensitized recipients of renal allografts.Methods Immunoadsorption treatment was performed on 10 patients whose panel reactive antigen (PRA) was more than 40 %. The adverse effect and hyperacute rejection were observed.Results Two cases of acute rejection of renal allografts were found in highly sensitized recipients and reversed by the therapy of immunoadsorption and adjusting immuno-suppressive drugs.Conclusion Immunoadsorption treatment could effectively and safely prevent highly sensitized recipients from hyperacute rejection post-transplantation.

Objective To investigate the etiological diagnosis and therapy of liver function lesion after kidney transplantation.Methods By analyzing the etiological factor of 82 cases of liver function lesion,we provided a reasonable and operative therapy scheme in kidney post-transplantation.Results Of 82 cases,the number of drug toxicity and viral hepatitis B which result in liver functional lesion were 70 cases(85 5%) and 12 cases(14 5%) respectively.The former were all cured,8 cases in the latter were cured and the other 4 cases were died from acute hepatic failure.Conclusions The liver function lesion of post-transplantation should be diagnosed carefully and treated particularly.Morever,the adjustment of immuno-suppressive drugs and monitoring circlosporin A concentration should be done for the patients with liver function damaged.

Intracranial hypertension easily causes brain herniation,brainstem compression,and leads to death.Western medical treatment mainly chose medicines that can change the permeability of plasma,but with noticeable side effects.Chinese medicines had manifested therapeutic effects to inuacranial hypertension with multiple approaches and no obvious side effects.Besides Chinese medicines can also adjust the overall state of patients,which can not be replaced by western medicine.The treatment of intracranial hypertension with Chinese medicines will become an important research subject and have a broad outlook.

Objective To evaluate the safety and efficacy of adrenal autotransplantation for the treatment of persistent Cushing's disease after transsphenoidal pituitary tumor resection. Methods Four patients were treated by adrenal autotransplantation with attached blood vessels after bilateral adrenalectomy for persistent Cushing's disease from April 1991 to March 2008 in our institute. The four patients were 3 females and 1 male. Their ages ranged from 14 to 36 years, with an average of 30 years. Right adrenalectomy was performed 1 to 3 months before the left adrenalectomy. 30 % ?50 % of the left hyperplastic adrenal was placed in the left inguinal region with the anastomosis of the inferior epigastric artery and the central adrenal vein, and between the left saphenous vein and the incised adrenal envelope with the adrenal middle artery inside. The hormone replacement dosage decreased gradually after operation. They were followed up for 1.0, 1. 5, 8. 0 and 10. 0 years. The patient's symptoms, adrenal hormone (serum cortisol, urinary free cortisol and adrenocorticotroph) levels and the steroid replacement dosages were recorded and analyzed. Results The symptom of the Cushing's disease disappeared completely after operation and there was no Nelson's syndrome except one patient with slight darken skin. Through 4 ways of imaging examination, operation, clinical presentation and endocrine examination, the 4 transplanted adrenals functioned well with less steroid replacement dosage needed after operation. The 4 transplanted adrenal glands functioned steadily 1 year after the auto-transplantation, and no hyperplasia was detected in the transplanted adrenals with the stimulus of high dosage adrenocorticotroph. Conclusions The long-term effects of adrenal autotransplantation with attached blood vessels after bilateral adrenalectomy is effective and safe. Adrenal autotransplantation can be a feasible option for the treatment of persistent Cushing's disease.
