Objective To investigate the epidemiological characteristics and factors of hemorrhagic fever with renal syndrome (HFRS) during 1958 to 2007 in Fuyang.Methods Descriptive study method was used to analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome.The incidence peak of hemorrhagic fever with renal syndrome was computed by using rotundity distribution.The correlation was analyzed between incidence and virus index by Pearson correlation.Results 40 002 HFRS cases was reported during 1958 to 2007 in Fuyang and 2381 cases were dead.The average incidence and fatality rate of HFRS were 11.99 per 100 thousand and 5.95 percent respectively.Eight counties all had cases.Yingshang county had the highest cases and Jieshou city had the highest fatality rate.Since 1958,there're 4 incidence peak in Fuyang.The period of high incidence was during November to January of next year and the peak of incidence rate was on December 13.Indoor density and field density of mouse were 9.84 percent and 7.91 percent respectively.Virus rate of indoor and field of mouse were 9.21 percent and 6.99 percent respectively.During 1984 to 2007,the correlation coefficient between virus index and incidence was 0.58.In room brown mouse was the most before 2000,but then house mouse become the most.In open country heavy line Japanese fieldmouse is the most mouse all the time.Conclusions In Fuyang,the focus of HFRS is exist widely.Density and virus rate of mouse will directly affect the incidence.So surveillance among mouse should be strengthened.

Purpose To investigate the serum prostate specific antigen( PSA)feature of high grade prostatic intraepithe1ia1 neop1asia ( HGPIN)patients,and the association of the number of cores positive for HGPIN on initia1 biopsy and the risk of cancer deve1opment in second biopsy. Methods 492 cases of patients with suspicious prostate cancer were schedu1ed for transrecta1 u1trasound prostatic biopsy with an 8-core temp1ate. In the first biopsy,186 cases of patients with PCa,34 cases of patients with iso1ated HGPIN( on1y one core invo1ved with HGPIN)and 13 cases of patients with extensive HGPIN( two or more cores invo1ved with HGPIN),64 cases of pa-tients with LGPIN,195 cases of patients with BPH. The va1ues of PSA were ana1yzed and compared within these groups. In patients with extensive HGPIN or iso1ated HGPIN we proposed a repeat 8-core biopsy after 6 months independent of serum PSA 1eve1. The same measure was app1ied for patients diagnosed as LGPIN or BPH in the first biopsy with accompanying increase or persistent e1evation of serum PSA 1eve1. The incidence of PCa was ana1yzed and compared within these groups. Results The serum PSA 1eve1s were no sig-nificant1y different between LGPIN and BPH(P>0. 05),between iso1ated HGPIN and LGPIN(P>0. 05),and between iso1ated HG-PIN and BPH(P>0. 05). The serum PSA 1eve1s were significant1y different between extensive HGPIN and LGPIN(P<0. 05),be-tween extensive HGPIN and BPH(P<0. 05),and between extensive HGPIN and iso1ated HGPIN(P<0. 05). In the second biopsy, the incidence of PCa in patients with extensive HGPIN was 38. 48%,that in patients with iso1ated HGPIN was 9. 68%,that in patients with LGPIN was 12. 50%,and that in patients with BPH was 12. 20%. Conclusions The features of PSA in patients with iso1ated HGPIN are simi1ar to BPH,PSA 1eve1 in patients with extensive HGPIN were between PCa and BPH,and patients with extensive HG-PIN have a higher incidence of PCa in second biopsy than iso1ated HGPIN and BPH.

ObjectiveTo observe the effects of electro-acupuncture combined neuromuscular electrical stimulation (NMES) on dysphagia in patients after acute cerebral infarction (ACI).Methods180 ACI patients with dysphagia were divided into the function training group (n=45)，electro-acupuncture group (n=45), NMES group (n=45) and comprehensive rehabilitation group (electro-acupuncture combined with NMES group, n=45). They were assessed with drinking water test before and 3 weeks after treatment. ResultsThe drinking water test scores improved after treatment in all the 4 groups (P<0.05), and more in the electro-acupuncture group, NMES group and comprehensive rehabilitation group than in the function training group (P<0.05). The drinking water test scores improved the most in comprehensive rehabilitation group (P<0.05). ConclusionThe electro-acupuncture combined NMES can effectively improve the therapeutic effect on dysphagia in patients after ACI.

TSO18 gene was subcloned into the Pichia pastoris expression vector pPIC9K. The recombinant plasmid pPIC9K-TSO18 was transformed into P. pastoris GS115 by electroporation so that the plasmid will be integrated with chromosome of P. pastoris. The P. pastoris strains containing multi-copy recombinant were screened by G418 and induced by methanol. The expression product was analyzed by SDS-PAGE, Western blot, deglycosylation, and purified by Sephadex column, and was used to immunize mice. The results indicated that the target protein was efficiently expressed in P. pastoris, and glycosylated moderately, and had immunological activity. In a 5 liter fermentor, the expression level of the target protein was up to 2.54 mg/mL. These results will benefit for the development of genetically engineering vaccine.

Endometriosis is a common chronic gynecological disease with endometrial cell implantation outside the uterus.Angiogenesis is a major pathophysiology in endometriosis.Our previous studies have demon-strated that the prodrug of epigallocatechin gallate(ProEGCG)exhibits superior anti-endometriotic and anti-angiogenic effects compared to epigallocatechin gallate(EGCG).However,their direct binding targets and underlying mechanisms for the differential effects remain unknown.In this study,we demonstrated that oral ProEGCG can be effective in preventing and treating endometriosis.Additionally,1D and 2D Proteome Integral Solubility Alteration assay-based chemical proteomics identified metadherin(MTDH)and PX domain containing serine/threonine kinase-like(PXK)as novel binding targets of EGCG and ProEGCG,respectively.Computational simulation and BioLayer interferometry were used to confirm their binding affinity.Our results showed that MTDH-EGCG inhibited protein kinase B(Akt)-mediated angiogenesis,while PXK-ProEGCG inhibited epidermal growth factor(EGF)-mediated angiogenesis via the EGF/hypoxia-inducible factor(HIF-1a)/vascular endothelial growth factor(VEGF)pathway.In vitro and in vivo knockdown assays and microvascular network imaging further confirmed the involvement of these signaling pathways.Moreover,our study demonstrated that ProEGCG has superior therapeutic effects than EGCG by targeting distinct signal transduction pathways and may act as a novel anti-angiogenic therapy for endometriosis.

BACKGROUNDSo far, in China, there has been no effective or easy procedure to define the control of asthma. This study assesses the validity of Asthma Control Test in Chinese patients.

METHODSThree questionnaires (Asthma Control Test, Asthma Control Questionnaire and the 30 second asthma test) were administered to 305 asthma patients from 10 teaching hospitals across China. Spirometry was also used. Asthma specialists rated the control of asthma according to patients' symptoms, medications and forced expiratory volume in first second. The patients were divided into noncontrolled group and controlled group according to the specialists' rating. Reliability, empirical validity and screening accuracy were conducted for Asthma Control Test scores. Screening accuracy was compared among 3 questionnaires. The patients' self rating and the specialists' rating were also compared.

RESULTSThe internal consistency reliability of the 5-item Asthma Control Test was 0.854. The correlation coefficient between Asthma Control Test and the specialists' rating was 0.729, which was higher than other instruments. Asthma Control Test scores discriminated between groups of patients differing in the percent predicted forced expiratory volume in first second (F = 26.06, P < 0.0001), the specialists' rating of asthma control (F = 88.24, P < 0.0001) and the Asthma Control Questionnaire scores (F = 250.57, P < 0.0001). Asthma Control Test showed no significant difference with Asthma Control Questionnaire in the percent correctly classified, while the percent correctly classified by Asthma Control Test was much higher than 30 second asthma test. The patients' self rating was the same as assessment of the specialists (t = 0.65, P = 0.516).

CONCLUSIONThe Asthma Control Test is an effective and practicable method for assessing asthma control in China.
