As one of the first resident standardized training bases, department of ophthalmology of Shanghai Ruijin Hospital participated in this reform process from 2010. Relevant rules and regulations (training management system , training scheme implementation system and evaluation system ) were strictly obeyed. When new problems emerged, under the guidance of department in charge, a series of regimens were formulated and improved gradually by Ophthalmology Professional Committee of Shanghai Resident Standardized Training Department. Based on reviewing and summarizing the work in the last 3 years, some thoughts and suggestions on the resident standardized training in future were put forward ,in-cluding how to better solve the“heavily used, lightly cultured” problem, the“disregarding medical ethics establishment”problem, the“disregarding assessment of teachers”problem and the“disregard-ing obtaining employment”problem.

Objective To assess circulating miRNAs’diagnosis value of breast cancer.Methods Conducted PubMed,Embase, the Cochrane Library,CNKI,cqvip,and wangfang database search in any language before June 2014.A total of 12 publica-tions were included in the meta-analysis.Then,the meta-analysis was performed using Meta-Disc 1.4.Meanwhile,the diag-nostic sensitivity,specitivity,positive likelyhood ratio,negative likelyhood ratio and diagnostic odds ratio were pooled by ran-dom-effects models.And the overall diagnostic performance was estimated by summary receiver operating characteristic curves (sROC)approaches.Stata12.0 was used to evaluated the publication bias.Results The pooled sensitivity was 80%(95%CI 0.77~0.82),specificity was 78% (95%CI 0.75~0.81);positive likelihood ratio was 4.09 (95%CI 2.80~5.99), negative likelihood ratio was 0.22 (95%CI 0.15~0.31),diagnostic odds rations was 20.64 (95%CI 10.24~41.62).The AUC for circulating miRNAs was 0.89 with Q value of 0.82.Publication bias was observed in existing literatures.Conclu-sion Circulating miRNAs is a potential biomarker in the diagnosis of breast cancer.

Aim To study the proliferative effect of resveratrol pretreatment on oxygen-glucose deprivation/reoxygenation ( OGD/R ) injury of rat cortical neural stem cells ( NSCs ) in vitro. Methods Isolation and purification of NSCs in neonatal Sprague-Dawley( SD) rats were conducted by suspended cultivation. The third passage NSCs of adherent culture was cultured under oxygen and glucose deprivation for 150 min and reoxygenation for 24 h. The experimental subjects were divided into normal, control, ethanol and resveratrol pretreatment groups. Immunofluorescence was used to identify NSCs. Cell viability was detected with CCK-8 assay. Flow cytometry cell cycle and BrdU assay were used to measure cell proliferation. Results Cells both in suspended and adherent cultivation highly expressed neuroepithelial stem cell protein ( nestin ) . Compared with the control group, NSCs viabilities and prolifera-tion in resveratrol groups (1, 5, 20 μmol·L-1 ) were significantly heightened, and highest in the 5 μmol · L-1 resveratrol group ( P<0. 05 ) . Conclusion Res-veratrol pretreatment can reduce injury and promote proliferation of NSCs after oxygen-glucose deprivation /reoxygenation.

In order to study the analgesic effect of Shaoyao Gancao Decoction, this paper discussed material basis and mechanism from the perspective of macromolecules in traditional Chinese medicine. Inspired by the phenomenon of turbidity after boiling Chinese medicine, this experiment took Shaoyao Gancao Decoction as the research object to study the formation process of precipitation during boiling. The results showed that aggregates with a certain shape were formed in the solvent during the boiling process, and the precipitate was obtained by standing and centrifuging. Analysis found that the precipitation was mainly composed of small molecules such as paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid, isoliquiritin and gallic acid, and macromolecules such as protein and polysaccharide. The composition of precipitate was consistent with that of Shaoyao Gancao Decoction, but the analgesic effect of Shaoyao Gancao Decoction after removing the precipitate was significantly reduced. Based on these results, we isolated small molecular compounds, polysaccharides and protein from Shaoyao Gancao Decoction and their contents are 60.4, 700.7 and 207.2 mg·g^-1 respectively. We get the ratio, polysaccharide: small molecule = 11.6∶1, protein: small molecule = 3.4∶1, the precipitate is prepared in the state of boiling. The characterization results showed that the particle size of the precipitate will change significantly after co-heating, and the content determination results showed that the content of the six small molecular compounds which was free in solvent was significantly reduced after the formation of the precipitate. The acetic acid writhing experiment proved that the precipitate has a good analgesic effect, and effectively reduced the levels of inflammatory factors prostaglandin E2 and nitric oxide, and increased the level of anti-inflammatory factor interleukin-10. These results proved that the precipitate in Shaoyao Gancao Decoction is an important material basis for analgesic effect, and macromolecules such as protein and polysaccharide are the main components of the precipitate. The study of macromolecules in the precipitate of Shaoyao Gancao Decoction not only provides new ideas and methods for elucidating the pharmacodynamic material basis of Shaoyao Gancao Decoction, but also provides a reference for analyzing the scientificity of traditional decoction.

OBJECTIVETo investigate the inhibitory effect of puerarin on invasive and metastatic abilities of tumor cells, and its possible mechanism through observing its impacts on the migratory, adhesive and invasive capacities of human oophoroma cells HO-8910 to the artificial recombined basement membrane.

METHODSExpression of estrogen receptor (ER) in HO-8910 cells was detected using PCR assay. Effects of puerarin on HO-8910 proliferation was detected with MTT assay; on its adhesion potential was tested with cell-matrigel adhesion assay, and on invasive and migratory capacities were measured with Transwell matrigel invasion assay and Transwell motility assay respectively.

RESULTSER was positively expressed in HO-8910 cells. After being treated with 20 micromol/L puerarin for 12 h, the adhesive test showed that OD value in the tested group was significantly lower than that in the control (P < 0.01), the inhibiting rate reached 50.63%; and the Transwell assay showed a significant lowering of penetrated cells (P < 0.01), the inhibition rate for invasion was 38.59% and that for motility migration 40.63%. The number of penetrated cells was lower in the group intervened with combination of Puerarin and estrogen than in the group intervened with estrogen alone, 33.40 +/- 3.30 vs 48.05 +/- 3. 56 for invasion and 35.35 +/- 3.03 vs 52.45 +/- 1.04 for motility (all P < 0.01).

CONCLUSIONPuerarin can inhibit the adhesion, invasion and migration of HO-8910 cells, plays an antagonist effect against the stimulation of estrogen on the malignant behavior of tumor cells.
