[Poking reduction cannulated screw for the treatment of SandersⅡ calcaneal fracture].

Objective: To evaluate clinical effect of poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture.

Methods: From October 2014 to December 2017, 28 patients with Sanders Ⅱ calcaneal fracture were treated with poking reduction cannulated screw guided by Pingle orthopedic muscle-bone interoperability balance theory, including 20 males and 8 females, aged from 24 to 55 years old with an average of (37.2±3.

Efficacy, safety, and immunogenicity of an oral recombinant Helicobacter pylori vaccine in children in China: a randomised, double-blind, placebo-controlled, phase 3 trial.

Background: Helicobacter pylori is one of the most common gastric pathogens, affecting at least half the world's population, and is strongly associated with gastritis, peptic ulcer, gastric adenocarcinoma, and lymphoma. We aimed to assess the efficacy, safety, and immunogenicity of a three-dose oral recombinant H pylori vaccine in children in China.

Methods: We did this randomised, double-blind, placebo-controlled, phase 3 trial at one centre in Ganyu County, Jiangsu Province, China.

Glycyrrhetinic Acid protects the heart from ischemia/reperfusion injury by attenuating the susceptibility and incidence of fatal ventricular arrhythmia during the reperfusion period in the rat hearts.

Background/aims: Licorice has been used to treat many diseases, including palpitations, in both Eastern and Western societies for thousands of years. It has been reported that glycyrrhetinic acid (GA), an aglycone saponin extracted from licorice root, exerts protective effects on the cardiovascular system, limits infarct sizes and protects against the development of arrhythmia. However, the mechanisms underlying the effects of glycyrrhetinic acid on the cardiovascular system remain poorly understood.

[The influence of different processing on the content of flavones of Dendranthema morifolium].

Objective: To investigate the effect of different processing methods on the content of luteolin-7-O-beta-D-glucoside, acacetin-7-O-beta-D-glucoside, luteolin, and acacetin of Dendranthema morifolium.

Methods: The optimal conditions were achieved on phenomenex, synergi Fusion-RP (5 microm, 4.6 mm x 250 mm)analytical column with a gradient mobile phase consisting of methanol and 0.

[Effects of glycyrrhetinic acid on sodium ion channel currents of rats' ventricular myocardial cells].

Objective: To study the effects of glycyrrhetinic acid (GA) on the sodium ion channel currents (I(Na)) of rats' ventricular myocardial cells, and to explore its anti-arrhythmic mechanisms at the ion channel level.

Methods: Single ventricular myocardial cells was isolated from SD rats. The whole cell patch clamp was used to record the effects of GA on I(Na) of rats' ventricular myocardial cells.

Roles and mechanisms of ginseng in protecting heart.

Ginseng, the root of Panax ginseng C. A. Mayer, has long been used clinically in China to treat various diseases.

Photophysical and electrochemical properties of donor-acceptor conjugated oligomers based on 3,4-ethylenedioxythiophene and deficient rings.

The photophysical and electrochemical properties of four novel donor-accepter (D-A) conjugated oligomers a-d based on 3,4-ethylenedioxythiophene (EDOT) and electrondeficient heterocycle rings were investigated. The UV-vis absorption spectroscopy, fluorescence emission spectroscopy and cyclic voltammertry studies suggest that the oligomers are expected to provide enhanced charge-transporting properties for the development of efficient electroluminescent materials. Furthermore, the third-order nonlinear optical (NLO) measurements made by Z-scan technique indicate that they have good third-order NLO response and are desired materias for fabricating nonlinear photonic devices.

[Chemical constituents of Carya cathayensis and their antitumor bioactivity].

Objective: To investigate the chemical constituents of Carya cathayensis and their antitumor bioactivity.

Methods: The compounds were isolated by Sephadex LH-20 and silica gel column chromatography. Their structures were identified by physicochemical properties and spectroscopic analysis.

Green tea drinking, high tea temperature and esophageal cancer in high- and low-risk areas of Jiangsu Province, China: a population-based case-control study.

Epidemiological studies suggested drinking green tea is inversely associated with esophageal cancer but results remain inconclusive. Moreover, inconsistent observations found high temperature drinks are associated with esophageal cancer. A population-based case-control study was conducted in a high-risk area (Dafeng) and a low-risk area (Ganyu) of esophageal cancer in Jiangsu province China from 2003 to 2007.

Association of smoking, alcohol drinking and dietary factors with esophageal cancer in high- and low-risk areas of Jiangsu Province, China.

Aim: To study the main environmental and lifestyle factors that account for the regional differences in esophageal cancer (EC) risk in low- and high-risk areas of Jiangsu Province, China.

Methods: Since 2003, a population-based case-control study has been conducted simultaneously in low-risk (Ganyu County) and high-risk (Dafeng County) areas of Jiangsu Province, China. Using identical protocols and pre-tested standardized questionnaire, following written informed consent, eligible subjects were inquired about their detail information on potential determinants of EC, including demographic information, socio-economic status, living conditions, disease history, family cancer history, smoking, alcohol drinking, dietary habits, frequency, amount of food intake, etc.
