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.

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.

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.

This article introduces a new technology of prosthetic disc nucleus replacement to treat lumbar disc herniation. The preliminary clinic experience, short time following ups, indications, contraindications, size and method of the technique were discussed. It was noted that some patients had short but heavy lumbago after the operation but the pain was relieved after oral medication. It will be a trend in the future spine surgery to restore the functions of spine unit. The prosthetic disc nucleus is a good choice before a total disc prosthesis replacing or spine fusion.

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

Smoking is one of the major risk factors for stroke. Both active and passive smoking may increase the risks of stroke, and the risks of stroke may decrease after smoking cessation, even no significant difference with non-smokers. Because of the different age, sex, smoking quantity, years of smoking, and regions of the smoking popuation, their strokes and the risks of all stroke subtypes are also different.

Objective To explore the effect of Mcl-1 small interference RNA ( siRNA) on tumor necrosis factor-re-lated apoptosis-inducing ligand ( TRAIL)-induced apoptosis in gastric cancer HGC-27 cells. Methods The apop-totic rates of cells treated with TRAIL and pan-caspase inhibitor ( z-VAD-fmk) alone or combination were measured by propidium iodide (PI) method using flow cytometry. The activation of caspase-3, cleavage of PARP-1, as well as the protein level of anti-apoptotic Bcl-2 proteins Bcl-2, Bcl-XL and Mcl-1 before and after TRAIL treatment were monitored by Western blot analysis. Transfection of Mcl-1 siRNA was performed using Lipofectamine 2000 reagent. The efficiency of gene silencing was quantified by Western blot and the effect of Mcl-1 siRNA on TRAIL-induced apoptosis was measured using PI method. Results HGC-27 cells were resistant to TRAIL-induced apoptosis, and z-VAD-fmk pretreatment could block apoptosis nearly completely. Activation of caspase-3 and cleavage of PARP-1 occurred in the late stage of apoptosis. The expression levels of Bcl-2, Bcl-XL and Mcl-1 were not altered after exposure to TRAIL. Transfection with Mcl-1 siRNA could obviously downregulate the expression evel of Mcl-1 in HGC-27 cells and enhanced the sensitivity of cells to TRAIL-induced apoptosis. Conclusion Overexpression of Mcl-1 may account for the resistance of HGC-27 cells to TRAIL.ownregulationof Mcl-1 by siRNA can effectively enhance the sensitivity of HGC-27 cells to TRAIL-induced apoptosis.
