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.

Objective To investigate the significance of human cyomeg Movirus(HCMV)pp65 IgG antibody avidity index(AI)for the clinical diagnosis of HCMV primary infection through the experimental model of HCMV primaly infection in BALB/c mice.Methods 6～8 weeks,female,specific-pathogen-free BALB/c mice were divided into 5 groups.6 mice in each group. And he mice were injected with 2×106 PFU/m1,2×105 PFU/mi,2×104 PFU/ml,2×103 PFU/ml and 2×102 PFU/ml of HCMV intraperitoneally respectively. Another 6 mice were injected intraperitoneally with the maximum dose of HCMV kept at 56℃ for 30 min as inactivated virus group.And HF negative control group was established at same time. All the mice ere sacrificed to obtain brain and lung tissues for the following experiments after 1 montll.(1)Tissue samples obtained from mice were inoculated in human embryo fibroblasts(HF)monolayers after routine treatment for virus isolation.HCMV specific eytopathie effect(CPE) was observed bv inverted phase-contrast microscopy.HCMV UL83 DNA in the ultures as tested by PCR and pp65 antigen was detected by indirect immunofluorescence.(2)Extracted mRNA from tissue samples and HCMV pp67 mRNA were analyzed by reverse transcriptase PCR(RT-PcR).(3)Immunoglobulin M(IgM)antibody and immunoglobulin G(1gG)antibody avidity Was investigated for their usefulness in distinguishing primary genital HCMV infections rom nonprimary infections with ELISA kit using truncated pp65 protein.ResultsHCMV can be isolated in the tissues from the mice injected with 2×106 PFU/ml and 2×105 PFU/m1.RT- PCR and ELISA showed positive results in the same groups.The infective rates were 100%.The analysis of the low doses groups,inactivated group and HF negative ontrol group all showed negative results.Conclusions BALB/c mice can be infected with HCMV and appeared as primary infection after1 month.Determination of HCMV pp65 IgM and HCMV p065 IgG-AI by ELISA incorporated with virus isolation and RT-PCR are helpful for distinguishing primary infections from nonpfimary infections.The detection of HCMV p65 IgM and HCMV pp65 IgG-AI by ELISA utilizing recombinant protein pp5 as antigens can be used for preliminary screening.

Inhalation chemotherapy and immunotherapy is a developed technique for respiratory neoplasm recently. It is easy manipulated with high local response and little side effects. The drugs include 5 FU,DDP, taxol, camptothecin,interleukin 2 and GM CSF, etc. Inhalation chemotherapy and immunotherapy have been successfully applied for the therapy of primary lung cancer as well as the lung metastases other tumor.

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.

Objective: To study dieting status and prevalence of eating disorder in female students of colleges in Beijing Method:211 female students were investigated with Dieting Status Measurement, Eating Disorder Symptom Questionnaire (EDSQ), Drive for Thinness and Body Dissatisfaction of EDI, Experience of Shame Scale and Sex Role Inventory Result:Female college students showed more serious tendency of dieting than those had been found in middle or high school girls Ten students of our subjects met the criteria of eating disorder not otherwise specified by EDSQ The body mass index (BMI) and drive for thinness could predict on dieting behavior There was no significant difference between the scores on dieting and scores of sex role, while there were substantial differences existing in Experience of Shame Scale and its subscales among subjects with different type of sex role

Objective: To explore the brain damage effects of lysophasphatidyl choline(LPC) in rats with pancreatitis and explore the pathogenesis of pancreatic encephalopathy(PE).Methods: SD rats were divided into test group,control group one and control group two at random.Acute edematous pancreatits rat model was induced following Aho HJ method for test group and control group one,then test group rats were venously applied with LPC and control group one was injected saline through tail vein.Control group two was treated with venous injection LPC through the rat tails without operation.Horseradish peroxidase(HRP) was used as a tracer to detemine if the blood-brain barrier(BBB)was open 7～10 days after successive application of LPC.The extravasated tracer was showed by diaminobenzidine(DAB).Rat brain tissue sections were examined by ponceau stain and Luxol Fast Blue stain to determine whether the rat brains were demyelination at the same time.Results: The BBB permeability of the test groupLTU rats increased greatly and obvious demyelination was observed in test group rat brains while both control groups had basically intact BBB and scarce demyelination was observed in both control groups.A statistical difference existed between the test group and control groups.Conclusion:LPC definitely open the BBB of the rat pancreatitis and demyelinates the brain of pancreatitis rats thus LPC plays an important role in the pathogenesis of PE.
