Abstract
A survey was conduct to analyze the usage situation of post-exposure prophylaxis(PEP) and related factors among men who have sex with men(MSM) in 6 cities of Shandong Province. Total of 2 620 subjects, the use ratio was 2.98% (78/2 620). Compared with age≤24 years,monthly income<5 000 yuan,non-commercial sex, non-DU,non-STD,role for being insert in the anal intercourse,MSM was more likely to use PEP with age≥45 years(OR=3.87, 95%CI:1.12-13.36),monthly income≥5 000 yuan(OR=1.87, 95%CI:1.07-3.28),commercial sex (OR=3.13, 95%CI:1.56-6.28), drug users (DUs) (OR=4.63, 95%CI:2.51-8.52),STD patient (OR=2.35,95%CI:1.05-5.27),the mixed sex role group(OR=2.25,95%CI:1.10-4.62).

Abstract
The physiological function of the reticulorumen plays an essential role in ruminant nutrition, and detailed knowledge of rumen motility can further advance understanding of ruminant nutrition and physiology. Rumen motility was simulated by setting different stirrer rotation speeds in a rumen simulation technique (RUSITEC) system. The aim of this study was to investigate the effects of rotation speeds on rumen fermentation, saturation factor of dissolved gases, hydrogen (H2) and methane (CH4) emissions, microbial protein synthesis, and selected microbial population using RUSITEC. The experiment was performed according to a balanced 3 × 3 Latin square design, and each period included 7 d for adaptation and 3 d for sampling. Three motility treatments included 5, 15, and 25 rpm rotation speeds. Daily total gas and H2 and CH4 emissions had quadratic responses to the increasing rotation speed and were highest at 15 rpm. Quadratic and linear responses (highest at 5 rpm) to increasing rotation speed were observed for saturation factors of H2 and CH4, liquid-dissolved H2 and CH4 concentrations, and headspace concentration of H2 in the gas phase, whereas increasing rotation speed linearly decreased saturation factors of CO2 and liquid-dissolved CO2 concentration. Quadratic and linear responses to increasing rotation speed were observed for molar percentages of acetate, ammonia, and microbial protein concentration, whereas increasing rotation speed quadratically increased pH and decreased total volatile fatty acid concentration and acetate-to-propionate ratio. The 15-rpm rotation speed had the highest values of total volatile fatty acids, acetate molar percentage, and microbial protein concentration. Quadratic and linear responses to increasing rotation speed were observed for copy numbers of solid-associated fungi and fluid-associated bacteria, fungi, and protozoa, while increasing rotation speed linearly increased copy numbers of solid-associated protozoa. Rotation at 15 rpm increased populations of fungi and protozoa in the solid rumen contents and the population of bacteria and fungi in the liquid rumen contents. In summary, this study provides insights on the biofunction of proper rumen motility (i.e., at a rotation speed of 15 rpm), such as improving feed fermentation, increasing gas emissions with decreased dissolved gas concentrations and saturation factors, and promoting microbial colonization and microbial protein synthesis, although further increase in rotation speed (i.e., to 25 rpm) decreases feed fermentation and microbial protein synthesis.

Abstract
A survey was conducted to analyze the HIV testing status and related influencing factors of male sexually transmitted diseases(STD) patients attending 18 county-level hospitals in Shandong Province from July 2015 to August 2016. The HIV detection rate of 1 570 subjects was 77.58% (1 218/1 570), and the HIV-antibody positive rate was 0.99% (12/1 218). Compared with general hospitals patients, urinary and anorectal patients, non-sexual patients, and patients with negative attitudes toward HIV testing, patients were more likely to be tested for HIV from specialized hospitals (OR=3.74, 95%CI:2.53-5.54), the skin and venereal section (OR=1.92, 95%CI: 1.31-2.79), the STD group (OR=2.02, 95%CI: 1.34-3.03) and patients with positive attitude (OR=15.20, 95%CI:10.74-21.52).

Abstract
Objective: To analyze the epidemic features of male HIV-infected and AIDS patients by sexual transmission in Shandong Province. Methods: Data on HIV-infected people and AIDS patients (HIV/AIDS) were derived from HIV/AIDS Comprehensive Response Information Management System. To analysis the epidemiological data of male HIV/AIDS by sexual transmission reported in Shandong Province from 1997 to 2016. Results: A total of 8 584 HIV/AIDS were reported by heterosexual transmission or homosexual transmission from 2007 to 2016. 2 421 cases were reported by heterosexual transmission and 6 163 cases were reported by homosexual transmission. Among cases infected by heterosexual transmission. The average age of cases infected by heterosexual transmission was (38.13±12.39) and (31.62±10.22) among cases who infected by homosexual transmission (t=24.95, P<0.001). 84 cases were reported by homosexual transmission and 138 cases by heterosexual transmission from 2007 to 2008, and 6 079 cases were reported by homosexual transmission and 2 283 cases by heterosexual transmission from 2009 to 2016. A total of 770 cases were dead after reported. Among the dead cases, 337 cases were infected by homosexual transmission and 433 cases by heterosexual transmission (χ(2)=328.21, P<0.001). 61.4% of the dead cases by heterosexual transmission were no longer than 6 months after reported and 54.3% in homosexual transmission (χ(2)=3.96, P=0.047). Conclusion: Homosexual transmission has been the main transmission of HIV/AIDS in Shandong Province. Epidemiological features and social demographic characteristics of each sexual transmission were different. As part of HIV cases developed to death in 6 months.

Abstract
A solar cell based on the n-MoS2/i-SiO2/p-Si heterojunction is fabricated. The device exhibits a high power-conversion efficiency of 4.5% due to the incorporation of a nano-scale SiO2 buffer into the MoS2/Si interface. The present device architectures are envisaged as potentially valuable candidates for high-performance photovoltaic devices.

Abstract
We measured the thermal properties of Nd:Lu₃Sc₁.₅Ga₃.₅O₁₂ (Nd:LuSGG) crystal, including the thermal expansion coefficient, specific heat, and thermal diffusion coefficient. The calculated thermal conductivity is 4.4 W/mK at room temperature. A high-power continuous-wave and passively Q-switched Nd:LuSGG laser was also demonstrated. Continuous-wave output power of 6.96 W is obtained which is the highest power with this material. For the first time to our knowledge, the passively Q-switched Nd:LuSGG laser is reported with the shortest pulse width, largest pulse energy, and highest peak power are achieved to be 5.1 ns, 62.5 μJ, and 12 kW, respectively. By spectral analysis, it has been found that the Nd:LuSGG laser was located at 1059 nm under low pump power, and became dual-wavelength at 1061.5 and 1059 nm when the incident pump power is over 2.27 W. The generating mechanism of dual-wavelength laser is also discussed.
