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.

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.

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.

The pathogenesis of diabetic retinopathy is complicated.The vast network of multiple factors including unifying mechanism,inflammatory reaction,neuron degeneration and metabolic memory of glucose,and the four established pathogenic molecular pathways are hotspots of mechanism research for diabetic retinopathy.Nevertheless,these researches may be only one corner of the iceberg of DR mechanism,and we still face enormous challenges in DR mechanism research.Collaboration with multiple disciplines to study the relationship between DR and diabetes and other systemic diseases,search novel therapy targets may increase the result in an unexpected windfall for DR basic research.

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 .
