Effects of Sevoflurane Inhalation During Cardiopulmonary Bypass on Pediatric Patients: A Randomized Controlled Clinical Trial.

The effects of sevoflurane inhalation during cardiopulmonary bypass (CPB) on postoperative courses and serum cardiac troponin I (cTnI) concentrations in pediatric patients undergoing cardiac surgery have not been extensively investigated. In this single-center, prospective, randomized trial, an anesthetic regimen containing 2% sevoflurane used throughout the CPB process was compared with a total intravenous anesthesia (TIVA) regimen. One hundred and three patients undergoing congenital heart defect repair with CPB were included in this prospective randomized controlled study.

[Effects of distance between residence and hemodialysis unit on cardiovascular complications and treatments of maintenance hemodialysis patients].

Objective: To explore the effects of etiological classification and the distance between residence and hemodialysis unit on cardiovascular complications and treatments in maintenance hemodialysis (MHD) patients.

Methods: A total of 756 MHD patients were collected from 12 hemodialysis centers of Guiyang, China between January 2011 and May 2012. Their distribution characteristics and correlations were based on medical records.

Polymorphisms of angiotensin converting enzyme and nitric oxide synthase 3 genes as risk factors of high-altitude pulmonary edema: a case-control study and meta-analysis.

High-altitude pulmonary edema (HAPE) is a non-cardiogenic type of pulmonary edema developing altitudes > 2,500 m. Angiotensin converting enzyme (ACE) and nitric oxide synthase 3 (NOS3) play important roles in regulating pulmonary vascular tone. To assess associations between genetic variants in the ACE and NOS3 genes and HAPE risk, 27 HAPE patients and 108 matched controls were genotyped and analyzed.

[Systematic review of water treatment technologies in the natural disaster striken area].

Systematical evaluate the literature about application and effect of post-disaster water treatment methods in the recent 20 years through a comprehensive search and collection, to provide the best evidence for decision-making of post-disaster water treatment in the future. The main conclusion are the methodology of water treatment and supply in disaster rescue of developed countries and the world has been comparatively formal and mature. Some simple methods of water supply and treatment play a relatively important part in the disaster rescues.

Molecular characterization of Tb, a new approach for an ancient Brucellaphage.

Tb (Tbilisi), the reference Brucellaphage strain, was classified as a member of the Podoviridae family with icosahedral capsids (57 +/- 2 nm diameter) and short tails (32 +/- 3 nm long). Brucellaphage DNA was double stranded and unmethylated; its molecular size was 34.5 kilobase pairs.

[Molecular characterization of embB306 gene in Mycobacterium tuberculosis isolates from tuberculosis patients in Chongqing municipality].

Objective: To understand the characteristics of embB gene mutation of Mycobacterium tuberculosis (MTB) isolates from tuberculosis patients in Chongqing, and the value of embB306 as a molecular marker used to diagnose ethambutol (EMB)-resistant MTB strains.

Methods: Direct sequencing was used to analyze the polymorphism of embB mutation in 51 EMB-resistant MTB strains and 50 EMB-sensitive MTB strains. And diagnostic testing was used to evaluate the value of embB306 as a molecular marker of EMB -resistant MTB strains as compared with the traditional sensitivity test.

[Development of a model for the diagnosis and risk classification on anthrax through artificial neural network].

Objective: Based on data through clinical and epidemiological studies, a model regarding the diagnosis and risk classification on anthrax was developed by artificial neural network (ANN). The model could integrally diagnose anthrax cases, judge the risk tendency in time, and increase the ability of recognizing the anthrax accidents.

Methods: Clinical, laboratory and epidemiological data from anthrax cases was collected and analyzed.

[Effect of qiangyi jiangtang capsules on diabetes mellitus model rats].

Objective: To study the pharmacodynamics of qiangyi jiangtang capsules (QJC) to offer the scientific foundation for clinical treatment to model rats of diabetes millitus induced by high lipid forage and streptozotocin.

Methods: The model rats of diabetes mellitus were induced by intraperitoneal injection of 0.6% streptozotocin (30 mg/kg body weight) given to Wistar rats after feeding with high lipid forage for a month and followed by fasting for 18 hours.

[Study on the nucleic acid of E. coli bacteriophage with broad host range and its sterilization effect to sewage samples from the environment].

Objective: To study the change of nucleic acid sequence and the germicidal effect of an E. coli bacteriophage with broad host range isolated from hospital sewage as well as to study the mechanism of phage host specificity and the effect of killed bacteria by phage-disinfectant to the samples from sewage water.

Methods: To extract the nucleic acid from phage f(2) and phage with broad host range using anti-serum-carbamidine hydrochloride assay.

[Studies on the germination of Bacillus anthracoides spores induced by nutrient germinant].

Objective: To explore the germination effects of Bacillus anthracoides spores germinant to nutrient germinant.

Methods: Heat factors and nutrient germinant were used to stimulate the Bacillus anthracoides spores and to germinate. Ultraviolet spectrophotometer was used to measured the A value of spore solution in the wavelength of 600 nm.

[Study on meteorological factors-based neural network model of malaria].

Objective: In order to provide reliable data for strategies development on prevention, a meteorological factors-based predicating model for malaria forecast was studied.

Methods: Data on malaria occurrence and climate changes from 1994 to 1999 in counties in Yunnan province was collected and analyzed with software packages of FoxPro 6.0 and Excel 5.
