Objective: To learn the knowledge, attitude and behaviors of AIDS of men who have sex wth men ( MSM ) in a gay bathhouse, so as to provide evidence for AIDS prevention and control among MSM. Methods: From April to June of 2017, the MSM in a gay bathhouse in Wuhan were investigated. Demographic information, awareness of AIDS related knowledge, attitude towards HIV infection, dating ways and purposes, and high-risk sexual behaviors were collected and analyzed. Results: Among 278 MSM responded, 235 ( 84.53% ) were aware of the basic knowledge of AIDS. The awareness rates of " transfusion with HIV blood will be infected ", " sharing syringes with HIV infected people will be infected ", "proper use of condoms can reduce the spread of AIDS ", " only having sex with one partner ( or few partners ) can reduce the spread of AIDS " were more than 90%, while the awareness rate of " high risk of HIV infection in gay bathhouses " was only 56.12%. Most respondents cared about the HIV infection situation of MSM, accounting for 74.46% ( 207 cases ) ; most denied or did not know the condition of friends infected with HIV, accounting for 82.37% ( 229 cases ) . The main purpose of coming to gay bathhouses was to find sexual partners, accounting for 87.41% ( 243 cases ) . About 52.16% had sexual behaviors with both heterosexual and homosexual partners, and 66.21% of them did not often or never use condoms when having sex with heterosexual partners. Conclusions The MSM in a gay bathouse have lower awareness of HIV infection situation and their partners, both heterosexual and homosexual behaviors, and lower proportion of insisting on condom use.

Objective To detect the in vitro effect of the traditional Chinese medicine on the tachyzoites of Toxoplasma gondii. Methods Supernatant (1^5 ml) of different doses of the traditional Chinese medicine (Changqing capsule) was collected by normal saline immersion and 2^5?10+4 Toxoplasma gondii tachyzoites were added in each paste well for 8 hours. Spiramycin, pyrimethamine and azithromycin in different doses were used as controls. Normal saline was used as negative control. Mice were inoculated with drug-treated tachyzoites intraperitoneally or intragastrically. The normal mice were subcultured after 8 days for 3 generations. Results The incident number of the infected mice was significantly different among groups with different drugs and doses: 2/60, 16/60, 10/60 and 10/60 in the groups of Changqing capsule, spiramycin, pyrimethamine and azithromycin respectively (P

BACKGROUNDUsing the most comprehensive available data on lung cancer incidence and mortality in China, the mortality time trends were described and the incidence and mortality profile in 2000 and 2005 were estimated and projected, so as to provide evidence and reference for clinic, basic research and making prevention and control strategy for lung cancer in China.

METHODSThe Joinpoint model was used to analyze the lung cancer mortality trends during 1987-1999, based on data reported to WHO from the Ministry of Health in China. Combined with the data from the second national mortality survey in 1990-1992 and the lung cancer incidence and mortality data from several cancer registries in China which involved in Cancer Incidence in Five Continents, the 8th version, using the log-linear model (based on Poisson distribution), the incidence and mortality profile for lung cancer in 2000 and 2005 in China were estimated and projected.

RESULTSThe age-standardized mortality rates increased during the study period, especially in rural areas (the expected annual percentage changes were 2.7% in men and 3.6% for women, both were statistically significant) and showed among almost all age groups (above age 15). From 2000 to 2005, there would be 0.101 million more lung cancer deaths (from 327643 in 2000 to 428936 in 2005) and 0.116 million more new incident cases (from 381487 in 2000 to 497908 in 2005).

CONCLUSIONSDue to the double effects from both changes in the risk factors for the disease and the population growth and aging, lung cancer is becoming one of the most common and increasing malignant neoplasmin China . The prevention and control for this disease will be theemphasis for future cancer control strategy of China in which tobacco control is critically important .
