Objective To understand the schistosomiasis endemic situation of surveillance sites in order to offer the scientific evidence for schistosomiasis control in Yunnan Province.Methods According to the protocol of national surveillance of schistosomiasis,four national sites in Yunnan Province were surveyed and the results were analyzed.Results In the four surveillance sites in Yunnan Province,the average infection rate of schistosomiasis of residents was 1.92%,and the infection rates of cattle and water buffaloes were 3.65% and 6.59% respectively.The snail area was 99.44 hm2,and the average density of the snails was 0.37 snail/0.1 m2,and the snail infection rate was 0.08%.There was the feature of higher infection rate and lower infection intensity in residents in Yunnan.Conclusions The endemic situation of schistosomiasis falls obviously after the control.However,the domestic animals still play an important role in the transmission of schistosomiasis,and the snails are not well controlled in some sites.So the surveillance and control to cattle and the snail should be continuously strengthened.

Objective To investigate the expression of α-thalassemia/mental retardation syndrome X-linked (ATRX) in different central nervous system tumors and the meaningness in differential diagnosis. Methods Expression of ATRX protein was determined by immunohistochemistry in astrocytomas , oligodendrogliomas, glioblastomas, ependymomas and meningiomas. Results Positive expression levels of ATRX in astrocytomas were significantly lower than those in oligodendrogliomas,glioblastomas, ependymomas and meningiomas (all P <0.01). Conclusion The loss of ATRX was mainly occurred in astrocytomas, which could be as a astrocytoma marker in diagnosis.

Traditional clinical students training model is teacher-centered this education model has some defects.Whether an education model is advanced or not is relative to whether we can cultivate creative students with high quality.We use“one center, two auxiliarys,three stages”in our clinical education and fully utilize advanced education methods,combine theory with practice and cultivate creative students wiht high quality.

Objective To investigate the changes of serum apolipoprotein A-I and its clinical significance to acute respiratory infection.Method Totally 44 patients with acute respiratory infection were divided into three groups according to various concentration of Serum apolipoprotein A-I.They were procaleitonin(PCT)＜0.5 ng/ml group,0.5 ng/ml≤PCT＜2 ng/ml group and PCT≥2 ng/ml group.We measured apolipoprotein A-I,C-reactive protein,procalcitonin and albumin within 24 hours after admission.Results With the increase of serumPCT,the production of ApoA-I and albumin were down-regulated,while CRP up-regulated.Conclusions Apolipoprotein A-I has a sound relationship with the acute respiratory infection.It can be used as one of the diagnostic criteria in severe infection patients who have disorders of lipometabolism.

Objective To investigate the distribution and antimicrobial susceptibility of the bacteria isolated from bloodstream infections during 2013-2014 in Changhai Hospital for rational use of antibacterial agents.Methods The bacterial strains from blood samples were collected during the period from January 2013 through December 2014,and subjected to antimicrobial susceptibility testing by using automated system or Kirby-Bauer method.The results were interpreted according to CLSI M100-S24 breakpoints or FDA breakpoints.The data were analyzed by WHONET 5.6 software.Results A total of 1 048 nonduplicate isolates were collected,of which Escherichia coli,coagulase-negative Staphylococcus (CNS) and Klebsiella pneumoniae accounted for 29.5％,15.8％ and 13.8％,respectively.Gastroenterology,Hematology,General surgery,Urology and Department of Infectious Diseases are the top 5 departments according to their total number of bacterial isolates.The results of antimicrobial susceptibility testing showed that ESBLs-producing E.coli and K.pneumoniae accounted for 63.8％ and 38.6％,respectively.The prevalence of methicillinresistant CNS (MRCNS) was 77.6％.The E.coli strains isolated from Urology showed higher resistance rates to cephalosporins than the total E.coli strains,while the E.coli strains isolated from Gastroenterology showed higher resistance rates to betalactarn/beta-lactamase inhibitor combinations and carbapenems than the total E.coli strains.Higher prevalence of MRCNS was found in departments of Hematology,Urology and Neurosurgery.All the CNS strains isolated from Neurosurgery were resistant to methicillin.The K.pneumoniae strains isolated from Bum ICU had higher resistance rates to all the antibacterial agents tested than the total K.pneumoniae strains,while the K.pneumoniae strains isolated from Gastroenterology showed higher resistance rates to carbapenems and tigecycline than the total K.pneumoniae strains.Conclusions The pathogenic bacteria isolated from bloodstream infections vary with departments in terms of species distribution and antimicrobial susceptibility profile.It is necessary to strengthen the surveillance of antimicrobial resistance in hospital for rational use of antibiotics.

·Familial exudative vitreoretinopathy ( FEVR ) is a hereditary disease associated with abnormal angiogenesis in the pediatric period. The most prominent finding of the disease is avascularity in the peripheral retina. Whereas, the phenotypic features are variable. In some minor cases, missed diagnosis would happened due to asymptom, while, in severe FEVR, neovascularization, retinal exudation, retinal folds, macular heterotopy and retinal detachment may occur and give rise to extremely poor vision or even blindness. Mutations in the FZD4, LRP5, NDP, TSPAN12, ZNF408, and KIF11 genes have been reported to contribute to FEVR with X - linked recessive, autosomal dominant, and autosomal recessive inheritance manners. We have summarized aspects of pathogenesis, clinical features and classification, mutations genes as well as diagnosis and treatment of FEVR in this review.

Objective Depression and obesity are two major disorders associated with coronary heart disease ( CHD) , and both have a high prevalence. Different studies concluded different outcomes about the relation between body mass index ( BMI) and depression. The aim of this study was to assess the status of depression and investigate the relationship between de-pression and BMI in CHD patients using quantile regression. Methods 580 patients were enrolled. Depression was tested using the Zung Self-Rating Depression Scale ( SDS) . Demographic data and clinical data were recorded. Quantile regression was con-ducted to determine whether BMI was a predictor of depression. Results SDS scores were significant different in underweight, normal weight,overweight and obesity group (P<0. 001). Overweight and obesity patients were least depressed. Differences in SDS scores increased steeply as depression increased at 5th,10th,25th,50th,75th,90th and 95th percentiles,with the coefficients ranging from -0. 36 to -0. 88 in total population,-0. 26 to -1. 09 in male and -0. 46 to -0. 75 in female respectively. The effects of BMI on depression were significantly different in different quantiles of depression in total population ( P=0. 04 ) and in male (P=0. 006),but no difference in female. Conclusion There was also a phenomenon of "obesity paradox" between BMI and depression in CHD patients. The effects of BMI on depression were significantly different in different quantiles in total population and in male.

Prostate cancer is one of the common cancers in old men. Androgen ablation is a major option for the treatment of the metastatic diseases. However, most of the cancers progress to a more aggressive stage, so-called androgen-independent (or hormone refractory) relapse beyond any cure. The androgen receptor (AR) is an important factor in regulating the differentiation and proliferation of prostate epithelial cells, and also plays a critical role in cellular survival. Studies have demonstrated that aberrant activation of the AR is a major determinant in prostate cancer progression. We have provide a brief summary of AR-mediated cellular survival and an introduction to the advances of RNA interference techniques in silencing AR expression as a novel therapy for prostate cancer.

This study aimed to evaluate the effects of Pin1 inhibitor Juglone on proliferation, migration and the angiogenic ability of breast cancer cell line MCF7Adr. MCF7Adr cells were cultured and separately treated with Pin1 inhibitor Juglone (treatment group) and DMEM without drug (control group). The cell cycle was examined by flow cytometry. Cell migration was measured by wound-healing assay. Cyclin E protein content was detected by Western blotting. The angiogenesis factor vascular endothelial growth factor (VEGF) in cell media was determined by enzyme linked immunosorbent assay. The results showed that the percentage of cells in G2/M phase in treatment group was significantly higher than that in control group (25.5% vs. 10.1%, P<0.05), and that in G0/G1 phase and S stage in treatment group was significantly lower than that in control group (40.5% vs. 48.2%, and 33.7% vs. 41.7%, P<0.05). Cyclin E protein content in treatment group was significantly lower than that in control group (39.2 ± 7.4 vs. 100 ± 23.1, P<0.05). (A0-A24)/A0 value in treatment group was significantly lower than that in control group (23.9 ± 3.8 vs. 100 ± 14.4, P<0.05). VEGF-A, -B, and -C contents in cell media of treatment group were significantly lower than those in control group (P<0.05). It was suggested that Pin1 inhibitor Juglone can effectively inhibit the proliferation, migration and the angiogenic ability of MCF7Adr cells, and can be used as an alternative drug therapy for breast cancer.
