AIM To conduct a prospective assessment of anti-hepatitis E virus(HEV) Ig G seroprevalence in the Western cape Province of South Africa in conjunction with evaluating risk factors for *** consenting participants attending clinics and wards of Groote Schuur, Red cross children's Hospital and their affiliated teaching hospitals in cape Town, South Africa, were sampled. Healthy adults attending blood donor clinics were also recruited. Patients with known liver disease were excluded and all major ethnic/race groups were included to broadly represent local demographics. Relevant demographic data was captured at the time of sampling using an interviewer-administered confidential questionnaire. Human immunodeficiency virus(HIV) status was self-disclosed. HEV Ig G testing was performed using the Wantai? *** HEV is endemic in the region with a seroprevalence of 27.9%(n = 324/1161) 95%cI: 25.3%-30.5%(21.9% when age-adjusted) with no significant differences between ethnic groups or HIV status. Seroprevalence in children is low but rapidly increases in early adulthood. With univariate analysis, age ≥ 30 years old, pork and bacon/ham consumption suggested risk. In the multivariate analysis, the highest risk factor for HEV Ig G seropositivity(OR = 7.679, 95%cI: 5.38-10.96, P consumption(OR = 2.052, 95%cI: 1.39-3.03, P cent clinical case demonstrates that HEV genotype 3 may be currently circulating in the Western *** Hepatitis E seroprevalence was considerably higher than previously thought suggesting that hepatitis E warrants consideration in any patient presenting with an unexplained hepatitis in the Western cape, irrespective of travel history, age or ethnicity.

ATP Binding cassette sub-family B member 1 （ABcB1） affects disposition of many drugs and thus affects the pharmacokinetics of drugs and ultimately treatment response. Polymorphisms of ABcB 1 especially ABcB 1 c3435T polymorphism may thus affect pharmacokinetics of antiretroviral drugs and hence cD4 treatment response and other clinical outcomes of HIV patients. Methods： The study design was a historical cohort study and entailed collection of patient data. PureLink genomic DNA extraction mini kit was used for the extraction and purification of genomic DNA. TaqMan drug genotyping assay and protocol was used in the DNA amplification and genotyping. Data analysis was done using STATA software version 10. Results： Study participants with the cT genotype had lower creatinine levels after 6 months on lopinavir-based regimens compared with those with the cc genotype （p = 0.001）. In addition, the study participants with the cT genotype had consistently higher cD4 cell counts compared with those with the cc genotype from the time of ART switch but this was not statistically significant. However, there was no significant association between the ABcB 1 c3435T genotypes and haemoglobin and ALT levels. conclusion： There was a significant association between ABcB1 c3435T polymorphism and creatinine levels 6 months after therapy on lopinavir-based regimens.

关键词： ABcB 1 c3435T polymorphism lopinavir-based regimens creatinine levels cD4 cell counts ALT.

In order to make the fiber-based frequency synchronization system suitable for the use of large-scale scientific and engineering projects in which the ambient temperature of the fiber links change dramatically, we design a non-harmonic frequency dissemination system immune to strong temperature fluctuation. After the lab tests, in which the ambient temperature of the fiber fluctuates 40°c/day and 20°c/h, respectively, the relative frequency stabilities of this system reaches 4.0 × 10-14∕s and 3.0 × 10-16∕104 s. It is demonstrated that the proposed non-harmonic scheme shows a strong robustness to complicated working environment with strong temperature fluctuation.
