Results The 2007 result of the national HIV sentinel surveillance showed that the HIV prevalence among female sex workers,injecting drug users,men who have sex with men and pregnant women was 0.0%,1.9%,3.1% and 0.0% respectively;the data from the national HIV comprehensive response information system showed that by the end of 2007,72.8% of the adults and children with advanced HIV infection had received antiretroviral therapy (ART) ,and 83.6% of the ART receivers survived after 12 month treatment. Conclusion Indicators of the "Monitoring & Evaluation Plan" are able to reflect the outcomes and achievements of 2006-2007 HIV/AIDS response in China,which has made good progress and has fulfilled the mid-term targets as defined by the Plan.

BACKGROUND:Biological dressing A (porcine Xenoderm) and Physiotule Ag (Coloplast) show good effects on the absorption of exudates, adhesion and anti-bacteria in treatment of degree Ⅱ facial burns. OBJECTIVE:To observe the effectiveness of biological dressing Aversus Physiotule Ag after early debridement of degree Ⅱ facial burns. METHODS:A total of 15 patients with superficial degree Ⅱ facial burn and 10 patients with deep degree Ⅱ facial burns were included. Symmetric facial area of the same patient with the same depth of burn was divided into two parts of same size for treatments. One side was randomly selected as the experimental side, and treated with biological dressing A. The other was selected as the control side and treated with Physiotule Ag. We compared wound healing time, infection, times of changing dressings, skin after healing, drug change comfort and dressing comfort between the two sides. RESULTS AND CONCLUSION:In patients with superficial grade Ⅱ facial burn, times of changing dressings and drug change comfort were better in the experimental side than in the control side (P < 0.05), but the dressing comfort was better in the control side than the experimental side (P< 0.05). No significant difference in wound healing time, infection and skin after healing was detected between the two sides. In patients with deep degree Ⅱ facial burns, wound healing time, times of changing dressings, skin after healing and drug change comfort were better in the experimental side than in the control side (P < 0.05), but the dressing comfort was better in the control side than the experimental side (P< 0.05). No significant difference in infection was detectable between the two sides. Above findings suggested that the therapeutic effects of biological dressing A and Physiotule Ag were similar in treatment of degree Ⅱ facial burns. Biological dressing A in repair of deep degree Ⅱ facial burns promotes the wound healing andelevates the quality of healing.

Aim To further research into the antithrombotic mechanism of scorpion venom active peptides (SVAP). Methods Human umbilical vein endothelial cells (HUVEC) were cultured with enzyme digestive method. After the cultured HUVC was incubated in conditioned media for 1 hour, the effects of SVAP on the concentration of 6-Keto-PGF 1? and NO of HUVEC were determined with radioactive-immunolygic and nitrate reduction enzyme method respectively. Results As compared with control, SVAP in the doses of 1,5,10, 20 mg?L -1 had the distinctive increase of 54%, 68%,72%,79% of the concentration of 6-Keto-PGF 1? and SVAP in the doses of 10, 20 mg?L -1 had the significantly increased of 27%, 46% of the concentration of NO. Regression anylysis showed that the release levels of PGI 2 and NO in HUVEC induced by SVAP was of positive correlation. Conclusion Antithrombotic mechanism of SVAP is related to the increase of PGI 2 and NO released from HUVEC and synergistic and mediating action between NO and PGI 2.

Abstract?AIM: To obtain the prevalence and risk factors of symptomatic dry eye disease ( SDED ) among college students in China.?METHODS:Population-based cross-sectional study. Students in Medical School of Lanzhou University were approached. A questionnaire was used to evaluate the prevalence of SDED and its risk factors. The diagnosis of SDED was based on reported symptoms and was established if the participants reported “often” or “all the time” once or more for 6-item questionnaire. Positive tests included a tear-film breakup time ( TBUT)≤10s and a fluorescein staining score ( FSS ) ≥1. Demographic information and possible factors that may contribute to SDED were analyzed in a step-wise multivariate logistic regression modelto assess risk factors of SDED.? RESULTS: There were 1139 participants ( 84. 37%response rate ) have completed the questionnaire, 475 males and 664 females aged 16-26y. The prevalence of SDED was 18. 70% [95% confidence interval ( CI)= 16. 59-20. 81]. A TBUT of ≤10s and a FSS≥1 were noted in 47. 67%(95% CI=44. 95-50. 57) and 13. 97%(95% CI=11. 95-15. 99) for all participants, respectively. The multivariate regression analysis revealed the following risk factors:daily reading time of≥4h(OR=1. 58,95% CI=1. 15-2. 18), daily computer use of≥4h ( OR= 1. 52, 95% CI= 1. 02-2. 25), and constant eyeglasses wearing (OR=1. 54,95%CI=1. 08-2. 13). The female gender, refractive surgery and contact lens ( CLs) wearing were not risk factors for SDED in this analysis.? CONCLUSION: The prevalence for SDED is high in Chinese college students. The risk factors include daily reading time of≥4h, daily computer use of≥4h and constant eyeglasses wearing.

Objective To detect the sperm apoptosis rate and level of reactive oxygen species (ROS) in seminal plasma and explore their correlation among infertile males. Methods Ninety-two inferitile males were divided into varicocele (VC) group (n=32), leukocytospermia group(n=30) and the other cause group (n=30), and another 24 in vitro fertilization sperm samples were sereved as controls. The routine sperm parameters including seminal pH, sperm viability and sperm density were examined by computer assisted sperm analysis, the sperm apoptosis rate was asseseed using Annexin V/PI staining, and the ROS level in seminal plasma was detected by TBA method. The differences in seminal parameters between three infertile groups and control group were compared, and the correlation of sperm apoptosis rate with level of ROS in seminal plasma was explored in each group. Results The sperm viability of three infertile groups was significantly lower than that of control group (P<0.01). The sperm apoptosis rates and levels of ROS in seminal plasma in VC group and leukocytospermia group were significantly higher than those in control group (P < 0.05 or P < 0.01). The sperm apoptosis rate was positively correlated with the level of ROS in seminal plasma in leukocytospermia group(r=0. 573, P < 0.05). Conclusion The increased sperm apoptosis rate and level of seminal plasma ROS may be related to the infertility of patients with VC and leukocytospermia. The increased level of seminal plasma ROS may be one of the causes of increased sperm apoptosis rate in patients with leukocytospermia.

Objective To study the prevalence and trend of obesity among primary and middle school students in Beijing from 1985 to 2005.Methods Morphological data of students aged 7-18 from the National Physical Fitness and Health Surveillances of Chinese School Students in Beijing in 1985,1995,2000 and 2005 was analyzed with methods of cross-sectional study.The prevalence of obesity was calculated,and its secular trends was characterized.Results The prevalence of obesity among students aged 7-18 in Beijing were 0.65%,3.40%,5.23% and 8.53% respectively in the four surveillance programs with obvious rising trend which had an increase.In 2005,it was indicated that the obesity prevalence of subgroups were significantly different from each other.It was higher for males(11.11%)than females(5.98%),also for students aged 10-12(11.63%).In rural schools(6.60%)it was much 10wer than in urban(10.38%),but the areas with high SES was deemed to have a 10wer prevalence.Conclusion In the last two decades,among primary and middle school students in Beijing,obesity had changed its characteristics from sporadic to epidemic with the features of both developed and developing countries.

Objective To detect the relationship of pathological grade and stage of bladder cancer with common chromosomal aberrations of urine exfoliated cells by FISH. Methods A total of 99 urine samples were detected by FISH with probes of chromosomes 3,7,17 and 9p21 to collect pathological grade and stage information of bladder tumor tissues. Results (1) The aberrations of chromosome 3 and 17 had significant correlation with pathological grade and stage (P<0.05) but that of chromosome 7 had no correlation with pathological stage (P>0.05), but had correlation with grade (P < 0.05). The aberration of 9p21 had no correlations with pathological grade or stage (P > 0.05). (2)The polysomic chromosomal aberrations of chromosomes 3, 7 and 17 assessed correlated with high-grade and high-stage bladder carcinoma. The 9p21 deletion was found at a significant frequency in low-grade and low-stage lesions, when, 9p21 amplification was found at a significant frequency in high-grade and high-stage lesions. Conclusions Aberrations of the four chromosomes, especially polysomic chromosomal aberrations of the bladder cancer cases could present a possible trend toward greater chromosome increased with tumor grades and progressive stages of invasion.
