Setting Chinese as preparatory courses is an effective way to harmonize Chinese language teaching and medical teaching.By this way,some low-level students can be disqualified from further study,thus both the level of Chinese teaching and medical professional teaching can be improved.In the process of the eductional system reform from 5 years to 6 years,building Chinese training based preparatory course,will consummate the oversea medical undergrade education system.

After an analysis of the urgent need of systematic medical information service in village and township hospitals and doctors and the advantageous conditions for medical academic libraries to provide information service for them, its imple-mentation strategies were proposed and how to promote the construction of libraries and the development of medical cause in villages and townships by providing information service in countryside were pointed out.

Objective To observe the clinical effects of surgical treatment of retinal detachment(RD) caused by macular hole(MH) in high myopia. Methods The clinical materials of 149 eyes of 149 high myopia patients with RD caused by MH were reviewed. The cases were divided into complete posterior vitreous detachment (PVD) group and incomplete PVD group. The anatomic successful rate of operative treatment was evaluated according to the applications of vitrectomy surgery and non vitrectomy surgery respectively in each group. The visual acuity changes after the operations were also observed. Results The anatomic successful rates were as follow: 77.9% in total cases with vitrectomy surgery and 25.9% with non vitrectomy surgery ( P 0.05). Conclusions The scleral buckling combined with vitrectomy, gas intraocular tamponade and postoperative photocoagulation is an effective and optimal procedure for RD caused by MH in high myopia.

Spinal cord injury is a traumatic disorder resulting in a functional deficit that usually leads to severe and permanent paralysis.Now several strategies including pharmacological and rehabilitation therapies are not effective treatments for spinal cord injury.Recently stem cell transplantion caused extensive concerns from scholars because of its feasibility in theories and definite effectiveness in experiments.Stem cell types used in spinal cord injury therapy include embryonic stem cells,neural stem cells,mesenchymal stem cells and induced pluripotent stem cells.We extensively review the related articles in recent years,discusse and analyze current situations and perspectives of different stem cells transplantion for treating spinal cord injury.

This paper summarizes the observation and nursing of patients with postoperative complications following percuta-neous transhepatic cholangogrphic drainage(PTCD) and biliary tract stent implantation for malignant obstructive jaundice. A-mong thirty-two patients,eight had postoperative complications,including two with biliary tract hemorrhage,four with biliary tract infection,one with pneumothorax and one with bile leakage. All the thirty-two patients recovered well in clinical symptoms and quality of life. To attach importance to psychological nursing and postoperative health education are the key points in nursing care of patients with PTCD,which play important roles in alleviating clinical symptoms,improving treatment outcome and pro-moting the patients' quality of life.

Objective:To establish the model of pancreaticoduodenal transplantation in rats. Methods:The enteric drained whole pancreas duodenal transplantation model was investisated. The donor aortic segment including the celiac, superior mesenteric divergence were anastomosed with recipient abdominal aorta with end to side. The donor portal was cuff-anastomosed with left renal vein. The graft duodenum were anastomosed with the host jejunum with end to side. Results:Eighty-nine operations were performed and 51 rats were successful, of which all graft of successful case had endocrinium function. Conclusion:This model for pancreas transplantation is reliable.

This study aimed to review the research progress on the contribution of microRNA (miRNA) to the chemotherapy re-sistance of breast cancer. With“miRNA,”“breast cancer,”and“chemotherapy resistance”as key words, the literature was searched in Pubmed and CNKI databases between 01-2000 and 10-10-2012. We described the characteristics and mechanisms of breast cancer che-motherapy resistance and focused on the contribution of miRNAs in the chemotherapy resistance of breast cancer. MiRNA participate in chemotherapy resistance of breast cancer through different ways. This article summarizes different miRNAs that participate in che-motherapy resistance and identifies their specific pathways in drug resistance. The potential clinical utilization of the serum miRNA as a tumor marker is also discussed. Further research on the effect and mechanism of serum microRNA in chemotherapy resistance will bring a new chapter in the targeted therapy of breast cancer.

Pulmonary arterial hypertension is characterized by elevated pulmonary arterial pressure with high disabled rate and lethality.Since many causes could lead to pulmonary arterial hypertension,the mechanism studies were developed rapidly,and some new therapeutic targets have been explored according to the multiple pathogenic mechanisms and pathways.We summarized the potential and novel biomarkers of the mechanisms associated with pulmonary arterial hypertension,and categorized based on their relationship to endothelial cell dysfunction,inflammation,epigenetics,cardiac function,oxidative stress,extracellular matrix,etc.The biomarkers can help for diagnosis,sorting,disease severity assessment of PAH,in order to provide the basis for precision treatment and new therapeutic target development.
