Objective To understand the attitude of health workers towards people living with HIV and AIDS(PLWHA) and AIDS knowledge and desire for related training among them in selected hospitals in Beijing.Method Convenience sampling was used to select health workers from 32 hospitals of different levels in 4 districts within Beijing.Anonymous self-administrated questionnaires were used to collect the information regarding AIDS knowledge and desire for relevant training.Results A total of 1 292 health workers completed the questionnaire.They demonstrated a moderate level of general AIDS knowledge,but a low level of knowledge related to AIDS diagnosis and therapy.Of them 39.7% had received specialized AIDS training and 96% had strongly desire for such specialized training.Most health workers sympathized with PLWHA and understood their situation,while some of them were afraid of PLWHA and wanted to have minimal contact with PLWHA.91.3% of the health workers expressed that PLWHA should have the same rights to medical services.At the same time,49.2% of the health workers stated that they would not like to work in hospitals or departments which accepted PLWHA.80% of the health workers expressed concern over acquiring HIV infection in the workplace.52.7% of them thought that they had a risk of becoming infected in the workplace.Conclusion The level of AIDS knowledge among health workers in Beijing needs to be improved.Specialized training to enhance and develop health workers knowledge of prevention,diagnosis and treatment of AIDS is required.Most of the health workers do not discriminate against PLWHA,but they express concern over infection in the workplace.

Objective To develop the Chinese version of the 35-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and to assess the reliability and validity of MOS-HIV among HIV-infected individuals.Methods Between April and July of 2007,a croas-sectional survey of 758 HIV-infected individuals was conducted.Responses to the MOS- HIV were analyzed for its reliability and validity.Results Pearson's correlation coefficients of items for test-retest relia- bility ranged from 0.46-0.92,all internal consistency reliability coefficients exceeded 0.69,and all items were more strongly correlated with hypothesized scale than any other scale.Eight scales of MOS-HIV were significantly associated with CD_4 cell counts.Conclusions The Chinese version of MOS-HIV offers good reliability and validity and can be used as a tool to assess the quality of life of HIV infected individuals in China,thus providing evidence for further studying AIDS related quality of life in this country.

The JC virus is a widely infected human polyomavirus. Recent foreign researches showed that the JC virus infection is correlated with tumors of nervous system and digestive system, while, and study on the relationship between JC virus infection and gynecological tumor is seldom reported. In this study, we first establish the nucleic acid detection methods and procedures for JC virus and its highly homologous BK virus. The JC and BK viruses infection was evaluated by detect the viral DNA in samples including biopsy tissues, serum as well as urine of myoma of uterus (98 cases), cervical cancer (84 cases), endometrial cancer (40 cases) and ovarian tumor (72 cases) patients. The BK viral DNA positive rate was significantly higher in urine samples than that of blood and biopsy samples, and there is no significant difference of the BK viral DNA positive rate among all patient groups. The JC viral DNA positive rate is almost 0 in serum samples and biopsy. tissues, however, viral DNA positive rate is more than 50% in urine samples. In fibroids group, the JC viral DNA positive rate is up to 65. 3% which is significantly higher than that in other patients groups and healthy control. Further gynecological tumor associated viruses detection showed that only human papilloma virus infection is associated with cervical cancer, the herpes simplex virus, EB virus and cytomegalovirus infection is extremely low in our patient groups. No synergistic effect on gynecological tumor caused by viruses co-infection was observed. Our study showed that JC virus infection is highly related to the pathogenesis of uterine fibroids.

Objective To investigate the relationship between the expression level of HOTAIR and cellular radiosensitivity in esophageal squamous cell carcinoma (ESCC). Methods Four ESCC cell lines ( K150, K450, TE-1, and Eca109 ) were used in this study. Quantitative real-time polymerase chain reaction was applied to measure the expression level of HOTAIR in the above cell lines;colony-forming assay was applied to measure the survival fraction of different cells irradiated by different doses of X-ray. The t-test or analysis of variance was applied for analysis of differences. The correlation analysis was used by Pearson methods. Results The four cell lines all showed high expression levels of HOTAIR and radioresistance. Compared with the other three cell lines, Eca109 had a lower expression level of HOTAIR, a lower survival fraction at each radiation dose point, and significantly lower D0 and Dq . The mRNA expression level of HOTAIR and radiosensitivity were K150

AlM: To study an approach to visual acuity correction after intracapsular cataract extraction by phase - ll intraocular lens implantation through the individualized arcuate keratotomy.
METHODS: For demonstration, 48 postoperative patients ( 50 eyes ) receiving the intracapsular cataract extraction were gathered up. Each patient received a scleral tunnel major incision along the radial line of the maximum corneal refractive power determined by a cornea curvimeter, and a arcuate keratotomy was made opposite to the major one; through the major incision an iris-claw intraocular lens is implanted. Each patient was measured for their corneal astigmatism and uncorrected visual acuity before and after the surgery.
RESULTS: The results suggested the average corneal astigmatism before the surgery and that 3d, 1, 3, 6 and 12mo after the surgery as+3. 18±0. 68,-1. 56±0. 73,+0. 87± 0. 51, + 1. 21 ± 0. 70, + 1. 33 ± 0. 68 and + 1. 48 ± 0. 48 respectively.
