This article describes the introduction of concept of evidence-based medicine in gynecology and obstetrics education. We will use the problem-based education mode to improve the quality of gynecology and obstetrics education to bring up the students'habits of active learning,enhance their abilities of clinical thinking and promote their innovative consciousness.

BACKGROUND:Drug-eluting stents have achieved better treatment outcomes, but late stent thrombosis shakes its status. With the development of drug-eluting stents, loaded drugs are the key to reduce stent thrombosis. OBJECTIVE:To analyze the screening and application of drug-eluting stents. METHODS:A computer-based search was performed for literatures published from 2010 to 2016 in databases of PubMed and WanFang using the keywords of“drug eluting stents;rapamycin (sirolimus);paclitaxel;heparin;zotarolimus;everolimus”in English and Chinese, respectively. According to inclusion and exclusion criteria, 30 eligible literatures were included for analysis. RESULTS AND CONCLUISON:An ideal drug-eluting stent can selectively inhibit vascular smooth muscle and is expected to be anti-coagulated, but makes no effects on vascular endothelial cel s or promoting the cel proliferation. Most of the loaded drugs are antithrombotic and anti-proliferative drugs, among which, rapamycin-eluting and paclitaxel-eluting stents are extensively used. Regardless of delaying the proliferation of vascular endothelial cel s and increasing the thrombosis risk, most of drug-eluting stents are stil loaded with these two drugs, and only few stents loaded with rapamycin derivatives, such as everolimus, zotarolimus, tacrolimus and pimecrolimus. Current research focuses on developing a stent with rapid drug releasing and anti-proliferative capacity. Meanwhile, the combination of drugs and biphasic releasing are another novel idea.

OBJECTIVE:To provide reference for improving classification management and specifying standards of retail phar-macies in China. METHODS:The implementation status and standards of retail pharmacies'classification management in China were analyzed by using the method of comparative analysis. In view of the effects of classification management on retail pharmacy and its implementation difficulties,corresponding improvement measures were put forward. RESULTS & CONCLUSIONS:There are difference in the implementation status and standards of retail pharmacies'classification management in the national provinces and cities. Since the implementation of pilot in 2007,the main effects include retail pharmacies facing the survival of the fittest whipsaws pattern,the remote township small retail pharmacies facing a transition;the main implementation difficulties include gov-ernment failing to give a full propoganda the classification management of retail pharmacies,the construction of licensed pharma-cist team to be strengthened. It is suggested to include the ability of pharmaceutical care and credit level into the standard,imple-ment dynamic management,and complement classification management of retail pharmacies with the construction of licensed phar-macist team.

Bone marrow scintigraphy is a technology which is used in bone marrow mononuclear phagocytes may swallow colloidal imaging agent which is injected by intravenous, and the red bone marrow hematopoietic cells are consistent with mononuclear phagocytes. So it can indirectly observe the red bone marrow distribution. This technology can overcome disadvantage of the traditional biopsy which can only be partially drawn and can provide functional body imaging of bone marrow, simple and noninvasive. So it is used widely in the treatment of disease in the blood disease.

Non-communicable diseases (NCDs) are important diseases that affect human health. Obesity is one of the major biological risk factors of NCDs. With the growing national economy and the increasing standard of living, the obesity problem is highlighted and could raise even more attention. Oral health is vital to overall health. To gain more recognition and popularize the monitoring of obesity in dentistry, this paper illustrates the status of present studies between obesity and oral health.

Objective To investigate the expression of nm23,integrin ? 5? 1 and VEGF in breast cancer(BC),and the effect of the expression on the development of BC. Methods The expression of nm23, integrin ? 5? 1 and VEGF in 51 patients with breast cancer were examined by immunohistochemistry,and their correlatios were ananlyzed. Results The low expression of nm23 in BC tissue was associated with lymph nodes metastasis. The low expression of integrin ? 5? 1 and the high expression of VEGF in BC tissues were associated with the lymph nodes metastasis and low differentiation of the tumor.The expression of nm23 and integrin ? 5? 1 in breast cancer tissues had positive correlation(P

Objective To Study the clinical characteristics of the :sick sinus syndrome,(SSS) in elderly patients.Methods The disease onset age and causes, natural course and symptoms,dynamic electrocardiography(DCG) and cardiac pacing occasion were reviewed and analyzed. in 50 elderly patients had the diagnosis of SSS.Results The morbidity of SSS had increased significantly in elderly men over 70 years. The ordinary causes were coronary heart disease (CHD),specific SSS and the hypertensive heart disease,cardiomyopathy; and degenerative valvular heart disease etc.The mean natural course were about 10 years.The course of DCG type III was the longest one and the type IV was the shortest. The early symptoms were palpitation, dizzy and weakness,and the late symptoms were transient amaurosis, syncope and the worse cardiac angina and heart failure .The cardiac pacing was predicated by the clinical symptom's severity, which was determinated by both of the severity of bradycardia or sinus arrest and the patient's ability of compensation and adaptation.DCG was the commonly used diagnostic method for SSS in elderly patients.Conclusions The SSS has high incidence in elderly men over 70 and is caused by kinds of deasese,such as CHD and specific SSS,etc.The course is frequently intermittent,hide and very long the disease course. The early symptoms and DCG are atypical. The late symptoms commonly are transient amaurosis and syncope .and the late DCG has four types.The cardiac pacing was predicated by the clinical symptom's severity and DCG was the commonly used to diagnose SSS in elderly patients.
