OBJECTIVETo assess the acceptability of pre-exposure prophylaxis (Pr-EP) among the female sex workers in Xinjiang.

METHODSA volunteer-based, anonymous and one-to-one questionnaire survey was conducted in 762 female sex workers (FSW) in Urumqi and Kelamayi of Xinjiang Uyghur Autonomous Region.

RESULTAmong 762 FSW surveyed, 673 (88.32%) was not aware of pre-exposure prophylaxis with an awareness rate of 11.55%. The awareness rate of FSWs working in high-end entertainment venues was higher than that of FSWs working in medium-low end entertainment venues(P<0.001). Five hundred and twenty eight FSWs (69.29%) were willing to take Pr-EP, 145 (19.03%) were unwilling to take the medicine and 89 (11.68%) were possible to use the Pr-EP. There was no significant difference in willingness of using Pr-EP among FSWs working in high and medium-low end entertainment venuew (P=0.285). The subjects who were willing to take Pr-EP mainly concerned of the drug security, effectiveness and cost. The main reasons for not willing to take Pr-EP were: not having risk of infecting HIV, suspecting effectiveness of Pr-EP and worrying about side effects.

CONCLUSIONThe acceptability to use Pr-EP in female sex workers of Xinjiang is relatively high and the drug security, effectiveness and cost will influence the promotion and application of Pr-EP in the future.

OBJECTIVETo understand the influencing factors on the death of infants born to HIV infected mothers in areas with high prevalence of HIV/AIDS in China.

METHODSBased on the follow-up cohort study targeting at HIV/AIDS infected pregnant women and their babies initiated in 2004, a survey on the death status and influencing factors on the infants born to HIV/AIDS infected mothers enrolled in this cohort from Jan.2004 to Nov.2007 was carried out during Aug.to Nov.2008 in seven counties of four provinces in China. A total of 498 pairs of HIV-infected mothers and their infants were enrolled and their related information was collected. Single factor and multiple factors Cox model methods were adopted for data analysis.

RESULTSThe total observed person-years of 498 infants was 406.22, among which, 45 infants died, and the mortality density was 110.78 per 1000 child-year. A single factor Cox model showed, the pregnancy in pre-period of HIV/AIDS and HIV/AIDS period (RR = 1.971, 95%CI: 1.143 - 3.396), living status of the pregnancy (RR = 3.062, 95%CI: 1.097 - 8.550), multipara women (RR = 0.517, 95%CI: 0.278 - 0.961), natural childbirth (RR = 0.561, 95%CI: 0.345 - 0.910), premature labor (RR = 5.302, 95%CI: 2.944 - 9.547), low birth weight (RR = 4.920, 95%CI: 2.691 - 8.994), mother-child pairs taking antiretroviral drugs (RR = 0.227, 95%CI: 0.121 - 0.428) and infants infected HIV (RR = 5.870, 95%CI: 3.232 - 10.660) could affect the infants death. The death of HIV-exposed infants was influenced by various factors. The death risk of infants born to HIV infected mothers who were in the danger of pre-period of HIV/AIDS and HIV/AIDS period was greater than the infants delivered by HIV infected mothers who were in preclinical period of HIV/AIDS (RR = 6.99, 95%CI: 1.92 - 25.64). The death risks were greater in the group that the women whose CD4(+)TLC count number lower than 200 cells/microl (RR = 2.05, 95%CI: 1.01 - 4.15). The infants whose mothers had no ARV treatment had higher possibility to die than the others (RR = 6.17, 95%CI: 1.62 - 23.26). The death risk of premature delivered infants was 2.87 times of mature delivered infants (95%CI: 1.12 - 7.35). The death risk of HIV/AIDS infected infants was 9.87 times of the HIV/AIDS uninfected infants (95%CI: 3.81 - 25.62).

CONCLUSIONSome measurements including improving HIV-infected pregnant women's immunity, reducing mother to child transmission of HIV and premature birth, low birth weight are beneficial to reducing infant mortality.

The objective of study was to establish an animal model with thymic lymphoma in mice induced by intraperitoneal injection of DNA alkylating agent N-methyl-N-nitrosourea (MNU). Male and female mice of the C57BL/6 strain were injected by the intraperitoneal route with MNU solution in a dosage of 50 mg/kg body weight. The injection was repeated at week 8. Following injection of MNU, the general status of mice was observed. All mice were sacrificed for autopsy at the 22nd experimental week. Complete gross examination was performed for detection of tumor masses. The results showed that at the 22nd week, the incidence of thymic lymphoma in MNU-treated animals was 67.5% (27/40). No significant sex difference in the incidence of thymic lymphoma was observed. In conclusions, an animal model with thymic lymphoma in mice can be established by twice intraperitoneal administration of MNU. The biological behavior of the induced tumors resembles to those of human thymic lymphoma derived from thymic T-cells.

The objective of study was to investigate the origin and to classify the subtype of N-methyl-N-nitrosourea (MNU)-induced thymic lymphomas in mice. Histopathologic, immunohistochemical and ultrastructural studies were performed to analyze the pathological features of the neoplasms. The results showed that the thymus in all cases became totally replaced by sheets of cells of the lymphoid series. All the tumors coexpressed CD3 and TdT. Transmission electron microscopic study showed the plasma membranes of malignant lymphoma cells were smooth. The nuclear profiles were usually regular, with varying percentage of convoluted nuclei. Few cell organoids were observed in cytoplasm. In conclusion, all the MNU-induced tumor classified by histopathologic, immunohistochemical and ultrastructural studies as precursor lymphoblastic lymphoma that were unquestionably related to the thymus origin and T-cell lineage.

OBJECTIVETo investigate and analyze the therapeutic level and the existing problems on acute myocardial infarction (AMI) management in Beijing.

METHODSWe collected clinic data of 1242 AMI patients from 12 hospitals in Beijing, from January 2000 to March 2001, using a uniformed questionnaire, and evaluated the status of the diagnosis and treatment of AMI according to the Chinese guidelines issued on Decmeber 2001. Corresponding factors which influencing the mortality were also analyzed by one-way factor and multiple factors analysis methodologies.

RESULTSThe mean age of the 1242 AMI patients was 63.0 years old and about one third of them were under 55 years old. In hospitals, the total mortality was 9.10%. 37.9% of the patients had received therapy of the intravenous thrombolysis and emergency PCI with a total rate of reperfusion therapy as 56.0%. The in-hospital rates of drug use were as follows: Nitrates 90.0%, Aspirin 87.8%, heparin 88.7%, beta-blockers 73.4%, angiotensin converting enzyme inhibitors(ACEI) 77.6%, lipid regulating agents 43.6%. The rate of intravenous therapy of TCM by promoting the blood circulation and supplementing the vital energy was 30.5%. Results from multiple factors analysis showed that the compositive factors which could lower the mortality were reperfusion therapy,lipid regulating agents, intravenous therapy of TCM, beta-blockers, ACEI, lower molecule heparin and digitalis.

CONCLUSIONData from this study showed that there still existed a gap between clinical management on AMI and the guideline in Beijing. To set up a straightway passage of reperfusion therapy, to become more standardized to follow the guideline in undertaking the medical treatment practice, and to go deep into discuss the status of TCM on AMI management seemed the important tasks we are facing.

OBJECTIVETo evaluate the capability of multidetector CT (MDCT) for the diagnosis of arterioportal shunt (APS) associated with hepatocellular carcinoma (HCC).

METHODSTwo hundred and eighty-two patients with HCC were examined by both enhanced thin slice MDCT scanning in early hepatic arterial phase, late hepatic arterial phase, portal venous phase and digital subtraction angiography (DSA). The criteria for diagnosis of APS: (1) Earlier enhancement or stronger opacification of main portal trunk and/or the first order branches compared with that of superior mesenteric vein or splenic vein; (2) Earlier enhancement or stronger opacification of the second order and smaller portal venous branches compared with that of main portal trunk. The presence and degree of APS demonstrated with MDCT and DSA were analysed by double blind method.

RESULTSIn 282 HCC patients, 56 were complicated with APS. MDCT demonstrated central APS in 48 patients with 41 severe and 7 moderate shunt, one revealing no APS by DSA due to the giant HCC focus. Among 7 patients with light peripheral APS, two lesions were not revealed by DSA due to faint shunt and the last lesion in the patient with mixed APS was revealed both by APS and DSA.

CONCLUSIONMultidetector CT was a simple, effective and noninvasive new technique for the diagnosis of arterioportal shunt associated with hepatocellular carcinoma.
