Retrospective review on obstetric cases of critically ill and dead patients in Dongguan.

This retrospective analysis was set to understand the epidemiological status of the critically ill obstetric patients in Dongguan city, Guangdong, China. Understanding the risk factors for the death cases can provide scientific evidences for future preventive strategies to decrease the maternal mortality rate. This retrospective included the statistical data and clinical data on the cases of critically ill and dead obstetric patients admitted to Dongguan People's Hospital and Dongguan Maternal & Child Health Hospital from September 1st, 2009 to August 31st, 2013.

[Analysis on neutralization antibody titer of Japanese B encephalitis virus in healthy population in Shaanxi province].

Objective: To detect Japanese B Encephalitis virus (JEV) neutralization antibody (NA) titer and evaluate immunologic barrier, analyze the factor of affecting JEV NA titer, and provide the data for JE control.

Method: Cluster sampling was selected randomly in the region of high, middle, low JE incidence rate. To detect the NA of JEV by micro neutralization test.

[Evaluation on health education of hepatitis B control and prevention in reproductive age women in rural areas].

Objective: To evaluate the effect on health education of Hepatitis B control and prevention in reproductive age women in rural areas to put forward valuable recommendations for the strategies of Hepatitis B control.

Methods: A project was carried out in two counties in Shaanxi Province. The measures were conducted by strengthening health education, training of medical worker, reinforcing the management of pregnant women, preventing mother-to-infant transmission of Hepatitis B virus (HBV).

[Analysis on data from the clinical acute viral encephalitis surveillance system in three prefectures in Shaanxi during 2005 - 2006].

Objective: To describe the epidemiological features of viral encephalitis and burden of Japanese encephalitis (JE), and to identify potential strategies for effective JE control measures, using data from the Viral Encephalitis Surveillance Program (VESP) launched in Ankang, Baoji, and Weinan prefectures, Shaanxi province.

Methods: Data was gathered from sentinel hospitals reporting system on all the viral encephalitis (VE) cases identified between June 2005 and May 2007. County Center for Disease Control and Prevention (CDC) investigated the cases, drawing blood and cerebrospinal fluid (CSF) samples from the hospitals, and testing IgM antibody against JE using ELISA.

Molecular cloning of two exo-beta-glucanases and their in vivo substrates in the cell walls of lily pollen tubes.

Full-length cDNA sequences of two exo-beta-glucanases, LP-ExoI and LP-ExoII, secreted into cell walls of lily (Lilium longiflorum) pollen tube, were determined by RT-PCR. LP-ExoI exhibited over 80% similarity to LP-ExoII at both DNA and amino acid levels. RT-PCR showed that LP-ExoI transcripts were abundant in pollen grains and tubes, but could not be detected in leaf, stem, stigma, style, ovary, petal, filament, young root, young bud, and scale leaf of bulb.
