Impact of LDB3 gene polymorphisms on clinical presentation and implantable cardioverter defibrillator (ICD) implantation in Chinese patients with idiopathic dilated cardiomyopathy / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Objective: Mutations in LIM domain binding 3 (LDB3) gene cause idiopathic dilated cardiomyopathy (IDCM), a structural heart disease with a complicated genetic background. However, the association of polymorphisms in the LDB3 gene with susceptibility to IDCM in Chinese populations remains unexplored as dose the impact on clinical presentation. Methods: We sequenced all exons and the adjacent part of introns of the LDB3 gene in 159 Chinese Han IDCM patients and 247 healthy controls. Then we detected the distribution of polymorphisms in the LDB3 gene in all participants and assessed their associations with risk of IDCM. Additionally, we conducted a stratified genotypephenotype correlation analysis. Results: The A allele of rs4468255 was significantly associated with IDCM (P<0.01). The rs4468255, rs11812601, rs56165849, and rs3740346 were also associated with diastolic blood pressure (DBP) and left ventricular ejection fraction (LVEF) (P<0.05). Notably, a higher frequency of rs4468255 polymorphism was observed in implantable cardioverter defibrillator (ICD) recipients under a recessive model (P<0.01), whereas the significant association disappeared after adjusting for potential confounders. However, in the dominant model, notable correlations could only be observed after adjusting for multi parameters. Conclusions: The rs4468255 was significantly correlated with IDCM of Chinese Han population. A allele of rs4468255 is higher in IDCM patients with ICD implantation, suggesting the influence of genetic background in the generation of this response. In addition, rs11812601, rs56165849, and rs3740346 in LDB3 show association with brain natriuretic peptide, DBP, and LVEF levels in patients with IDCM but did not show any association with IDCM susceptibility.

Epidemiological Analysis of Traffic Deaths in Xiaoshan District from 2002 to 2007 / 预防医学

Objective To analyze the epidemiological characteristics of traffic deaths in Xiaoshan district which provides evidence for the prevention and control of traffic accidents. Methods Basing on the data obtained from death surveillance system of Xiaoshan from 2002 to 2007, ICD-10 was used to classify death causes. The mortality and proportion of death causes of traffic accident were calculated. Results The mortality of traffic accident was 26.28/100, 000, which ranked the first among all death causes of injury. The mortality in male was significantly higher than that in female, and increased with age. Death resulted from the vehicle-man collision was on the top among the 9 kinds of deaths due to traffic accidents, and 46.43% of death were the people over 60 years old. Motorcycle accident incidence was common in the age of 20 to 59 years old, accounting for 91.80% of motorcycle deaths, in which male was the major victims, accounting for 87.12%. Conclusion Traffic accidents have become an important public health issue in Xiaoshan District. Social departments should actively take measures to strengthen the propaganda and education of road traffic laws and regulatiens to reduce traffic accidents and deaths.

Effect of mica monomer powder on chief and parietal cells as well as G and D cells in gastric mucosa of chronic atrophic gastritis in rats / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study the regulative action of mica monomer powder preparation on the chief and parietal cells as well as G and D cells in the gastric mucosa of the experimental atrophic gastritis (CAG) rats.</p><p><b>METHODS</b>Intervention therapy was given to the experimental CAG rats at three different doses of mica monomer powder preparation to evaluate the changes of chief and parietal cells as well as G and D cells in the gastric mucosa and the histopathological changes of gastric mucosa.</p><p><b>RESULTS</b>Mica monomer powder preparation at three different doses could increase the amount of chief and parietal cells as well as G and D cells in gastric mucosa of the experimental CAG rats and alleviate and control the inflammation of gastric mucosa and the atrophy of gastric mucosa glands. Especially, better effects were shown in the mid and high dose groups.</p><p><b>CONCLUSION</b>Mica has the pharmacological action of protecting the gastric mucosa, enhancing blood flow of the gastric mucosa, and consequently improving the inflammatory responses of the gastric mucosa. One of the mechanisms is associated with promoting the secretion of gastric acid and gastric pepsin and regulating the neuroendocrine mechanism including gut hormone secretion (gastrin and somatostatin) by increasing the number of chief and parietal cells as well as G and D cells.</p>

Effect of mica monomer granule on gastrin, somatostatin and G cells as well as D cells of gastric mucosa in CAG rat / 中国中药杂志

<p><b>OBJECTIVE</b>To study regulative action of mica monomer granule preparation on gastrin (GAS), somatostatin (SS) and G cells as well as D cells of gastric mucosa in experimental chronic atrophic gastritis (CAG) rat.</p><p><b>METHOD</b>CAG rats were treated with mica monomer granule preparation with three different dosages--high, moderate and low level respectively. Changes of blood serum GAS, blood plasma SS and G cells as well as D cells of gastric mucosa in CAG rats were observed and detected with ELISA method, RIA method and immunocytochemistry method.</p><p><b>RESULT</b>Mica monomer granule of three different dosages could increase the quantity of G cells as well as D cells of gastric mucosa and the concentration of blood serum GAS and decrease the content of blood plasma SS in CAG rat at different level respectively. It was more effective in high and moderate dosage groups.</p><p><b>CONCLUSION</b>Mica has the pharmacological action of protecting gastric mucosa, promoting the palingenesis of gastric gland and enhancing blood stream of gastric mucosa consequently to abate the inflammation reaction of gastric mucosa. Its effective mechanism is associated with the neuroendocrine regulative mechanism of promoting the secretion of gastric acid and gastric pepsin by increasing the amount of G cells as well as D cells and the concentration of blood serum GAS, and reducing inhibiting action on GAS secretion and enhancing the secretion of GAS by decreasing the content of SS.</p>
