Nco-adjuvant endocrine therapy has provided opened new alternatives for locally advanced breast cancer, especially for patient groups such as the elderly, those who are not suited for chemotherapy, and those whose response may not be optimal. The latest generation of endocrine therapy for breast cancer,aromatase inhibitors, has proved superior to tamoxifen in terms of toxicity and efficacy in the adjuvant setting.Compared with neo-adjuvant chemotherapy, the appropriate patients to receive nco-adjuvant endocrine therapy can achieve similar short-term benefit. However, because of fewer long-term follow up results, the overall prognosis is not clear.

Transcatheter closure as an alternative to medical surgery has become a preferred therapeutic method to atrial septal defect (ASD).However,thrombopoiesis after occluder implantation has been reported comprehensively and causes a series of serious complications such as cerebral embolism、myocardial infarction,pulmonary embolism and so on.Reasons of device thrombopoiesis are closely associated with atrial fibrillation,persistent atrial septal aneurysm,occluder type,activated coagulation system and occluder endothelialization process.This paper summarizes correlation factors of occluder thrombopoiesis and current related prevention proposal after transcatheter closure of ASD,and provides theoretical and experimental foundation for prevenition of device thrombopoiesis after occluder implantation of ASD.

Objective: To analyze the efficiency and differences of China Community Health Service, to analyze the shares of eastern-middle-western regional differences and the difference within each region in the total efficiency difference. Methods: The super efficiency DEA model and decomposition of Gini coefficient by Subgroups are used to analyze the provincial data in China from 2008 to 2011. Results: The eastern-central-western regional difference is the major cause of the efficiency differences in China Community Health Service. In the meantime, the shares of the difference within each region in the total efficiency difference are also non-negligible. Conclusion: To narrow the efficiency differences among eastern, central and western areas; improve the inter-regional flow of community health service resources; improve the support and supervision on the backward regions; make regional policies to coordinate the internal resources of community health services and strengthen the assessment mechanism using efficiency as the indicator.

New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.

Objective Health promotion aims to empower people to enjoy good health by providing conditions at the micro-,meso-and macro-levels.So the organizational culture on which the target population rely in their daily lives should be considered as specific context for promoting their healthy behavior at the micro-level.The study of BANBANCHA,a specific form of sex industry in LZ city of southwest China,has revealed that it is characterized with culture of quasi-family and commercial sense.Accordingly,a relevant HIV prevention strategy has been developed,such as motivating the boss to participate in peer education,involving marketing discourse in health promotion,encouraging the target population to care for their own health,and integrating public and private topics into the health education activities.

Small renal calculus can be localized by B-mode ultrasonography form nine areas,four sections and three dimensions.Monitoring of its position is helpful in the detection and treatment of this conmon but not easy to be diagnosed disease.

Objective·To discusses the high risk factors and therapy strategies for ovarian hyperstimulation syndrome (OHSS). Methods·Seventy-seven cases with moderate and severe OHSS were collected to be retrospectively analyzed in Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine from January 2010 to December 2016. Results·Compared with non-pregnant patients, pregnant patients were more likely to have severe OHSS (P<0.05). Embryo transfer patients who underwent ovulation induction and oocyte retrieval became severe OHSS much more easily and had a much longer hospital stay than oocyte retrieval patients (P<0.05). Pumping ascites and pleural effusion or not has no effect on the length of hospital stay and the usage of low molecular dextran for patients with severe OHSS. Conclusion·The risk of OHSS should be evaluated to determine whether or not to carry out a fresh embryo transfer in patients who underwent ovulation induction and oocyte retrieval. For OHSS patients who have undergone embryo transfer or pregnancy, more attention should be paid to the progress of the disease, and individualized treatment is required.

Preventive effect of pollen, (at 5～10g/kg/d orally for 1 month) on obe-sity and elevation of lipid in serum and liver was observed in obese mice induced by sub-cutaneous injection of L-monosodium glutamate (MSG)2 mg/g from 1st to 5th day afterbirth. The results showed that in MSG-treated mice the body weight and weight of fatin groin, around kidney, and in abdominal cavity and also the Lee's index were all redu-ced by pollen given orally before onset of obesity caused by MSG and during development.The total cholesterol and triglyceride levels in serum and liver were much higher in theMSG mice than normal mice. These results indicated that ora1 administration of pollencould prevent obesity of MSG treated mice.

AIM: To investigate the adhesion between lymphocytes and extracellular matrix (ECM) in delayed-type hypersensitivity (DTH) in mice as well as the regulatory effect of several cytokines on it. METHODS: DTH was induced by the application of picryl chloride (PCl) to mice that had been sensitized twice by PCl, followed by isolating the spleen lymphocytes at different times. The adhesion of spleen lymphocytes to fibronectin or typeⅠcollagen were examined. In some cases, spleen lymphocytes obtained at 18 h were incubated with various concentrations of IL-2, IFN-?, and TNF-? for 4 h at 37℃ before the adhesion assay. T cells purified from the spleen lymphocytes were also used for the assay in the presence of TNF-?. RESULTS: The adhesion of spleen lymphocytes to ECM began to increase at 6 h after PCl challenge, reached a peak at 18 h, then decreased and returned to normal level at 36 h. IL-2 significantly increased the adhesion of lymphocytes to ECM at a dose of 1?10 5 U/L and TNF-? enhanced the adhesion in a concentration-dependent manner. The combined use of TNF-? and IFN-? showed a significantly enhanced adhesion. TNF-? was more effective to accelerate the adhesion of spleen T Cells than that of total spleen lymphocytes. CONCLUSION: In the process of DTH, the adhesion of lymphocytes to ECM was regulated by several cytokines and associated with the development of inflammation.

Quantitative determination of paeoniflorin in paeonialbiflosides by HPLC was described. The average recovery was found to be 101.08%, and relativc standard deviations (RSD)1.90%. The calibration curve was linear in the range from 2.0?g/ml to 10.0?g/ml with r=0.9999. It was shown that the method is convenient, sensitive and with good reproducibility.
