2.Information service of medical academic libraries in countryside
Chinese Journal of Medical Library and Information Science 2013;(12):39-41
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.
3.The importance of the chinese preparatory courses in the overseas medical undergraduate education
Chinese Journal of Medical Education Research 2006;0(07):-
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.

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.
8.Novel biomarkers for diagnosis and precision treatment of pulmonary arterial hypertension
Drug Evaluation Research 2017;40(2):141-147
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.

Objective To investigate apoptosis in acinar cells during posttransplant reperfusion, and the expression of Bcl 2, Bax, Fas Methods Pancreas transplantation was performed between male SD rats after 2 hours of cold ischemia Rats ( n =65) were divided at random into 7 groups: sham group, cold ischemia group (as controls), reperfused 1 h, 3 h, 6 h, 9 h, 12 h group The pathologic pancreatic tissue was observed by electron microscope; Apoptotic cells were stained by TUNEL technique; Expression of Bax、Bcl 2 and Fas protein in pancreatic tissue were detected by SABC immunohistochemical method Results Apoptotic cells were observed in early phase after pancreas transplantation The peak of apoptotic pancreas cells occurred 3 hours after reperfusion [AI ( 9 5? 2 9)%, P
10.Expression of Her-2 in gastric cancer and targeted therapy
Practical Oncology Journal 2014;(2):177-181
The incidence of gastric cancer is in the fourth place of all cancers in worldwide ,and the fatal-ity rate is in the second place .Standard chemotherapy regimens play an important role in prolonging gastric cancer survival rate.However,most of gastric cancers are in advanced stage when diagnose is finally made .The current medical practice can only meet the limited treatment options .In the last several decades ,study of the molecular mechanisms of gastric cancer gets constant new progress .By inhibiting the human epidermal growth factor receptor 2(Her-2)for advanced gastric cancer,it provides a new treatment for patients.Trastuzumab is a kind of Her -2 monoclonal antibody .It is the first kind of targeted therapy drug for the treatment of metastatic gastric cancer .A combination of trastuzumab with cisplatin and 5-fluorouracil based chemotherapy benefits gastric cancer overall survival.Overexpression of Her -2 provides evidence for the targeted therapy .So we reviewed Her -2 excessive expression of gastric carcinoma in recent years and represented by bead sheet resistance to targeted therapy .In this paper ,research of overpression of Her -2 and targeted threrapy in gastric cancer are summarized .
