A situ co-precipitation method to prepare magnetic PMDA modified sugarcane bagasse and its application for competitive adsorption of methylene blue and basic magenta.

Magnetic pyromellitic dianhydride (PMDA) modified sugarcane bagasse (SCB) was prepared by a situ co-precipitation method. Results showed that the magnetic modified SCB could be recycled easily by an applied magnetic field. Adsorption capacities of the magnetic sorbent for cationic dyes: methylene blue and basic magenta were 315.

HIV, HCV, and HBV co-infections in a rural area of Shanxi province with a history of commercial blood donation.

Background: Unhygienic blood collection in the early 1990s led to blood-borne infections in Central China. This study aimed to estimate human immunodeficiency virus (HIV) co-infection with hepatitis C and B viruses (HCV and HBV) and their risk factors in a rural area of Shanxi Province with a history of commercial blood donation.

Methods: A cross-sectional study was conducted in 2004.

[Prevalence and correlates of herpes simplex virus infections among AIDS patients in a county of Shanxi province, China].

Objective: To determine the prevalence of herpes simplex virus (HSV) and its correlates among HIV/AIDS patients in a county of Shanxi.

Methods: All HIV-infected patients in a county in Shanxi province who were receiving antiretroviral treatment (ART) were included in this study. Participants were interviewed using standard questionnaires.

[Survival and immune response of rural HIV/AIDS patients after free antiretroviral therapy].

Objective: To assess the adherence, immunologic and survival responses in HIV-infected patients receiving free antiretroviral therapy (ART).

Methods: All adult HIV-infected patients in Wenxi county who started antiretroviral treatment (ART) between 01 July 2001 and 31 December 2006 and aged above 18 years were included in this study. Epidemiological survey and laboratory tests were performed before, 0.

[An ambispective cohort study of the natural history of HIV infection among former unsafe commercial blood and plasma donors].

Objective: Discussing the natural history and the influencing factors of HIV infection among former commercial blood and plasma donors engaged in unsafe blood donation practices in China.

Methods: Using ambispective cohort study, with data obtained from ten counties (districts) from six provinces in the National AIDS Control Demonstration Area. HIV/AIDS cases were found and confirmed prior to July 24, 2006 being former commercial blood.

[A cross-sectional survey on human immunodeficiency virus infection in a former commercial blood donating community, Shanxi Province].

Objective: To determine the sero-prevalence of and the risk factors for human immunodeficiency virus infection among residents in a former commercial blood donating community, Shanxi Province.

Methods: A community-based cross-sectional survey was conducted among all residents aged 18 - 64 years in 4 villages in a rural county of Shanxi Province. A standardized structured questionnaire was administered to collect socio-demographic, medical and risk behavioral information.

[Epidemiology of pediatric HIV infection in six provinces of China].

Objective: To investigate the epidemiology of pediatric human immunodeficiency virus (HIV) infection in six provinces of China.

Methods: A cross-sectional study was conducted in six provinces with the highest HIV prevalence. Surveys on demographics and HIV-related questions (transmission modes, time of diagnosis, clinical stage, laboratory test) were distributed to clinicians in these provinces.

[A cross-sectional survey on hepatitis C virus infection among residents aged 18-59 years in a former commercial blood donating community, Shanxi Province].

Objective: To determine sero-prevalence of and risk factors for hepatitis C virus infection (HCV) among residents aged 18-59 years in a former commercial blood donating community, Shanxi province.

Methods: A community-based cross-sectional survey was conducted among 660 randomly selected residents aged 18-59 years from 12 villages in a rural county of Shanxi province. Structured questionnaire was administered to collect socio-demographic,medical and risk behavioral information.

[A retrospective cohort study on the natural history of human immunodeficiency virus among formal plasma donors in central China].

Objective: To study the time span from human immunodeficiency virus (HIV) infection to full bloom AIDS and to death.

Methods: Among formal plasma donors (FPD) from 2 counties in central China, 178 HIV cases were confirmed by western blot method but received no ARV treatment under a retrospective cohort study. Data on personal information, history on plasma donation, as well as dates regarding HIV diagnostic confirmation, onset of AIDS and death was collected through reviewing laboratory and medical records thus the course of disease for each case was identified.

[A retrospective cohort study on the survival of blood-borne human immunodeficiency virus cases in a county, China].

Objective: To understand the survival rate of adult blood-borne human immunodeficiency virus (HIV) cases in a county.

Methods: A retrospective cohort study was carried out to determine the survival from HIV infection and related factors among 78 adult HIV cases infected by blood and confirmed by the end of 2002. Kaplan-meier method was used to describe the survival distribution and Cox proportional hazard model was used to determine the factors associated with the survival time.
