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.

Objective To observe the clinical efficacy of enhanced external counterpulsation (ECP) in the treatment of non-proliferative diabetic retinopathy (NPDR).Methods It was a case-control study.83 patients (166 eyes) of NPDR were randomly divided into ECP treatment group (ECP group) and conventional therapy group (drug group) by date of visit odd and even number,each with 42 patients of 84 eyes and 41 patients of 82 eyes respectively.The blood glucose,glycated hemoglobin (HbAlc),low-density lipoprotein (LDL-C),corrected visual acuity,stages of diabetic retinopathy (DR) and hemodynamic index such as peak systolic velocity (PSV),diastolic velocity (EDV),resistance index (RI) of ophthalmic artery (OA) and central retinal artery (CRA) were not statistically different between these two groups (P＞ 0.05).All patients were regularly educated for lifestyle management and diabetes mellitus.The following parameters were controlled by drugs including blood glucose＜8.0 mmol/L,HbA1c＜7.5 ％,blood pressure ＜140/90 mmHg (1 mmHg=0.133 kPa) and LDL-C＜3.1 mmol/L.The ECP group received both ECP and medical treatments.The ECP parameters were gasbag pressure 0.35-0.45 kg/cm2,40 min/each time,1 time/d.35 days of ECP was one course,one course each year for 3 years.The treatment effectiveness was determined at the end of follow-up after 3 years of treatment.The blood glucose,HbA1c,blood pressure,LDL-C,visual acuity,fundus changes and hemodynamic index of OA and CRA before and after treatment were comparatively analyzed.Improved or stable visual acuity and fundus condition was judged as effective treatment.Results At latest follow up,the differences of blood glucose,HbA1c,blood pressure and LDL-C were not statistically significant (P＞0.05).Compared to drug group,the PSV and EDV of OA and CRA were increased,but RI of OA and CRA was decreased in ECP group (P＜0.05).The vision effective ratio was 91.67％ and 30.49％ in ECP group and drug group respectively with a significant different (x2 =65.56,P＜0.05).The fundus effective ratio was 92.86％ and 48.78％ in ECP group and drug group respectively with a significant different (x2 =43.38,P＜ 0.05).During follow-up,1 eye (1.19％) progressed to proliferative DR (PDR) in ECP group,while 6 eyes (7.32％) progressed to PDR in drug group.The difference of PDR incidence rate between two groups was significant (x2 =3.87,P＜ 0.05).During the ECP treatment,there were 2 patients with small blisters in the skin of lower limb and cured finally.There were no other treatment-related complications.Conclusion ECP in the treatment for NPDR can improve PSV and EDV,reduce RI of OA and CRA;improve vision and fundus state,reduce the incidence of PDR.

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.
