ABSTRACT
Objective@#To determine the first dengue fever case in Taizhou and trace probable transmission sources.@*Methods@#Collected serum of three patients for antigen, antibody and nucleic acid detection. Dengue viruses were isolated and cultured in C6/36 cell. The whole length of E gene was amplified by reverse transcriptase-polymerase chain reaction(RT-PCR) and then sequenced. The phylogenetic tree was drawn.@*Results@#Three cases were positive in nucleic acid detection. Two cases were IgM positive. One case was NSI antigen postive. Three strains of type I dengue virus were isolated from samples. The phylogenetic trees shown that the three strains were on the same branch. The identities of nucleotide were 99.87%. The identities of amino acid were 99.6%-99.8%.@*Conclusions@#The dengue virus strains isolated in Taizhou was imported from Guangdong or Southeast Asia and caused location infection.
ABSTRACT
Objective To understand the prevalence of group sex in men who have sex with men (MSM) and related factors in Taizhou,Zhejiang province.Methods From March 2013 to September 2015,a cross-sectional survey was conducted among MSM recruited from gay bars or bath houses in Taizhou by using questionnaire to collect the information about their sexual behavior and HIV test.Results A total of 1 435 MSM were recruited,179 of them (12.5％) were HIV infected,231 (16.1％) reported group sex during the past year.Compared with MSM without group sex,more MSM with group sex had more than ten male sexual partners (53.7％ vs.19.0％,x2=125.527,P＜ 0.01),had both male and female sexual partners (86.6％ vs.68.2％,x2=31.935,P＜0.01),used no condom at sex with female partners during the past year (28.1％ vs.19.8％,x2=6.540,P＜0.05).After adjusted for educational level and occupation,group sex was associated with age [≥ 50 years old vs.≤ 24 years old,adjusted odds ratio (aOR)=2.25,P=0.027],marriage with female (divorced or widowed vs.unmarried,aOR=0.29,P=0.001),census registering (local resident vs.non-local resident,aOR=1.56,P=0.023),number of male seuxal partners (≥21 vs.2-5,aOR=8.06,P＜0.001;11-20 vs.2-5,aOR=3.25,P＜0.001) and number of female seuxal partners (≥6 vs.0,aOR=2.63,P=0.005;2-5 vs.0,aOR=2.58,P=0.001;1 vs.0,aOR=2.01,P=0.010).Conclusion The prcvalcncc of group sex in MSM was high in Taizhou,and their poor condom use and complex sex behaviors would result in higher HIV infection rate and risk of transmission.

ABSTRACT
We report a case of a 47-year-old man who firstly complained of throat pain for half a month accompanied with fever. Specialized examination showed tonsils' hypertrophy and the laryngoscope found his right vocal cord was swelling and hyperemia. The routine blood test counted white blood cell as 31 x 10(9)/L, lymphocyte as 30. 84 x 10(9)/L while prolymphocyte could be seen with microscope. After that B-ultrasound scan gave spleen hypertrophy and multi-lymphatic-node enlargement. Peripheral blood flowcytometry and bone marrow biopsy finally diagnosed the man as actue myelocytic leukemia.
