Molecular epidemiology of mosquito-borne viruses at the China-Myanmar border: discovery of a potential epidemic focus of Japanese encephalitis.

Background: Mosquito-based arbovirus surveillance can serve as an early warning in evaluating the status of mosquito-borne virus prevalence and thus prevent local outbreaks. Although Tengchong County in Yunnan Province-which borders Myanmar-is abundant and diverse in mosquitoes, very few mosquito-based arbovirus investigations have been conducted in the recent decade. Herein, this study aims to evaluate the presence and the diffusion of mosquito-borne pathogens, currently prevalent in this region.

Research on monitoring method for thinning spinning process of the ultra-thin-walled cylinder based on the drum shape.

In order to perceive the state of the process of reverse thinning spinning of the ultra-thin wall tube, a monitoring method based on drum shape is proposed. The method uses the non-uniform rational basis spline curve fitting method based on the moving least squares method to reconstruct the outer contour data of the spinning zone collected by the line laser displacement sensor and extracts the outer contour curve of the drum zone according to the spinning characteristics. Then, the dynamic time warping algorithm is used to analyze the similarity between the current and previous drum curves in order to judge whether the current spinning state is abrupt or not.

Can Platforms Affect the Safety and Efficacy of Drug-Eluting Stents in the Era of Biodegradable Polymers?: A Meta-Analysis of 34,850 Randomized Individuals.

Objective: In the era of bare metal stents (BMSs), alloys have been considered to be better materials for stent design than stainless steel. In the era of biodegradable polymer drug-eluting stents (BP-DESs), the safety and efficacy of BP-DESs with different metal platforms (stainless steel or alloys) have not yet been reported, although their polymers are eventually absorbed, and only the metal platforms remain in the body. This study sought to determine the clinical safety and efficacy of BP-DESs with different platforms compared with other stents (other DESs and BMSs).

[Survey on intestinal nematode infections among school students in Tengchong County].

One primary school and one middle school were selected from Gudong Town, Tengyue Town and Puchuan Township of Tengchong County, respectively, by using the lamination stochastic group sampling method. The intestinal parasite infections were investigated with the iodine-stained direct smear method and modified Kato-Katz thick smears method. A total of 1 134 students were investigated and the total infection rate of intestinal nematodes was 12.

[Oxidative stress in patients with chronic hepatitis B before and after interferon alpha-2b treatment].

Objective: To investigate the impacts of interferon alpha-2b (IFN alpha-2b) on the oxidative stress states in the treatment of chronic hepatitis B (CHB) with different genotypes.

Methods: Thirty-five patients with chronic hepatitis B and 18 healthy volunteers as a control were enrolled in this present study. In control and patients group, the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), serum malondialdehyde (MDA) levels, serum total antioxidative stress capacity (TAC) were measured spectrophotometrically.

[Hemorheologic changes in patients with chronic hepatitis B].

Objective: To study the variation of the hemorheology in patients with chronic hepatitis B and study its relations with HBV DNA, liver function and oxidative stress markers.

Methods: Indices for hemorheology, oxidative stress markers, liver function, and HBV DNA were measured in 55 patients with chronic hepatitis B and correlative analysis was made.

Results: The low-shear whole blood viscosity (BV), RBC aggregation index were significantly higher in hepatitis B group than those in the control group (P < 0.

[Nitric oxide and nitric oxide synthase in patients with chronic hepatitis B].

Objective: To investigate nitric oxide (NO) and nitric oxide synthase (NOS) in patients with chronic hepatitis B.

Methods: Nitric oxide and nitric oxide synthase, including inducible NOS (iNOS) and constitutive NOS (cNOS), were measured in patients and control groups, then were statistically analyzed.

Results: NO and iNOS were significantly higher in patients with hepatitis B than in the controls (P < 0.
