To improve the standard screening, diagnosis, and treatment of hypertension in patients in China; realize the standardization of clinical practice of hypertension; and improve the prevention and control level of hypertension in China, it is both important and necessary to develop a clinical practice guideline for hypertension according to a recognized methodology. Jointly sponsored by the National Center for Cardiovascular Diseases, Chinese Medical Doctor Association, Hypertension Committee of the Chinese Medical Doctor Association, Chinese Society of Cardiology, and Hypertension Committee of Cross-Straits Medicine Exchange Association, the "Chinese Clinical Practice Guidelines of Hypertension" was proposed. Research Unit of Evidence-Based Evaluation and Guidelines, Chinese Academy of Medical Sciences, Guideline and Standards Research Centre of Chinese Medical Association Publishing House, Lanzhou University Institute of Health Data Science, and Lanzhou University GRADE Center will provide methodological support for the guidelines.

Objective:To investigate Helicobactor pylori (H. pylori) infection status and interfamilial transmission pattern in Zhengzhou area. Methods:A cross-sectional study was conducted from September 2020 to march 2021, among 731 individual from 266 families randomly selected from 9 communities of Zhengzhou area. H. pylori infection status was determined by serum antibody tests, and 13C-urea breath test was performed in the previously eradicated population to clarify the current infection status. The individual and familial infection rate, infection status for couples and children and adolescent were analyzed. Results:Among 731 individuals from 266 families, 397 of them were H. pylori positive. The individual infection rate was 54.31% (397/731); among infected individuals 77.83% (307/397) were infected with type Ⅰ strain, 22.67% (90/397) were infected by type Ⅱ strain. Annual household income ( χ2=0.419, 0.410, 0.213, all P>0.05), smoking history (χ 2=0.071, P>0.05), drinking history ( χ2=0.071, P>0.05), dining place ( χ2=0.009, P>0.05), gastrointestinal symptoms ( χ2=0.047, P>0.05), family history of gastric disease ( χ2=0.069, P>0.05), and history of gastric cancer ( χ2=0.004, P>0.05) had no significant differences between H. pylori-positive and -negative groups, but the infection rate in individuals with higher education level was lower ( χ2=4.449, P<0.05). The infection rate was significantly higher in≥18 age groups compared with<18 age groups ( χ2=6.531, 23.362, 20.671, 24.244, 37.948, 14.597 and 5.170, all P<0.05). The familial H. pylori infection rate was 87.59% (233/266), and in 61 families all member were infected (26.18%, 61/233). The positive rate was 23.08% (6/26) in 50 families with children under 18 years when both parents were infected. Among 231 coupled families, both couples were infected in 78 families (33.76%), one couple was infected in 113 families (48.92%), and both couples were not infected in 40 (17.32%). With the increase of marriage time, the infection rate of both spouses increased significantly ( χ2=7.775, 12.662, 15.487, all P<0.05). Conclusions:The distribution of H. pylori infection presents a family cluster pattern, and intrafamilial infection is an important transmission rout of H. pylori. The type I strain of H. pylori is the dominate strain in this area.

Adiponectin is recently described as an adipocyte secreting cytokine,which is abundant in human plasma,Adiponectin plays important roles not only in glucose and lipid metabolism but also in the development and progression of several obesity-related malignancies.Vascular formation is a key step in the cancer growth and metastasis.Current reserches find that the effect of adiponectin in cancer vascular growth still has great differenees.This review discusses the effect of adiponectin in malignant tumor neovascularization,and reveals that adiponectin can be a new vasoinhibitor.
