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

BACKGROUND:Tissue-engineered bone, as an emerging method, is used to repair bone defects, but it is difficult to be used widely because of no nutrient metabolism of implants. Pre-vascularized tissue-engineered bone research is performed for this limitation. Forward-looking and procedural vascular construction prior to artificial grafting is perspective to supply the nutrient metabolism of implants.
OBJECTIVE:To analyze the research results and developmental tendency of pre-vascularized bone engineering in vitro using a multilevel analysis.
METHOD:Literature search was performed in CNKI database for Chinese literatures and PubMed database for English literatures from 2000 to 2012. The key words included“tissue-engineered bone, vascularization, implant, osteoblasts, endothelial cel s, co-culture”in Chinese, and“bone engineering, endothelial cel s, osteoblast, implant, cel s co-culture”in English. A review addressing pre-vascularized tissue-engineered bone was completed based on retrieved literature classified according to bone physiological studies, in vitro experimental research and material research.
RESULTS AND CONCLUSION:Total y 60 articles were included in result analysis. Studied have documented that microvascular regeneration in normal bone tissue has an important role in osteogenesis regulation. Current bone tissue engineering research is to simulate this physiological process of vascular regeneration in the human body, and lots of in vitro studies are designed to complete this angiogenic process in bone tissue engineering. It is confirmed that in vitro pre-vascular work is used for bone tissue engineering, especial y for in vivo survival and ossification of tissue-engineered bone, pointing out the developmental direction for the clinical application of tissue-engineered bone.

Objective To explore the clinical efficacy of polyp of vocal cord. Methods The clinical data of 187 cases were retrospectively analyzed. Results According to the 187 cases, 164/187 cases were cured, 21 cases had obvious improvement, 2 cases have no effect, general effective rate is 98.9%. Conclusion Suspension laryngoscope were visual field widen and visual, every kind of surgical instruments binding equipments improve operation accuracy and reduce complication to acquire better clinical therapeutic effects.

Objective To evaluate the efficacy and safety of imiquimod 5% cream applied with different treatment courses for preventing the recurrence of condyloma acuminatum lesions.Methods A randomized,controlled clinical trial was conducted.Patients with condyloma acuminatum were divided into 3 groups (Group A,B and C).Group A was treated with CO2 laser only.Group B was given topical im- iquimod 5% cream three times a week over 4 weeks after laser treatment of visible warts.Group C was giv- en topical imiquimod 5% cream three times a week over 8 weeks after laser treatment of visible warts.All patients were followed up for 6 months.Results A total of 90 patients with anogenital warts were enrolled in,and finished the study.The recurrence rates of the Group A,B,and C were 64.29%,50%,21.88%,re- spectively,in 6 months of follow-up.The recurrence rate was statistically lower in Group C than in Group A and B (P=0.0033),and in Group C than in Group B (P=0.0457).Adverse reactions occurred in 73.33% and 84.38% of patients in Group B and C,respectively,which included erythema,itching,pain, burning,erosion,ulceration and flu-like symptoms.There was no significant difference of the frequencies of adverse reactions between Group B and C (P＞0.05).Conclusion The recurrence rate of anogenital warts declines significantly in patients treated with imiquimod 5% cream for 8 weeks,but not in the 4 weeks group,after laser therapy.The frequencies of adverse reactions are not significantly different in both groups.

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.

Target of the treatment for advanced pancreatic carcinoma is always palliative without prolongation of survival time almost, therefore the aims of treatment should be concentrated on improving the quality of life and alleviateing the disease-related symptoms. We do not call for the treatment and medicines that can incur obvious adverse reaction with limited effectiveness. Interventional therapy provides superexcellent short term efficacy with alleviating the disease-related symptoms significantly, and without severe side effects and thus coincides to the principle of the treatment for advanced pancreatic carcinoma. The surpassing advantages provide popular recommendation for this very kind of therapy in the recent years.

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.
