The potential molecular pathways of Astragaloside-IV in colorectal cancer: A systematic review.

Astragaloside IV (AS-IV), a traditional Chinese medicine, is often used to treat cancer. Colorectal cancer imposes a heavy burden on patients and society. It is essential to update the clinical evidence supporting AS-IV in the treatment of colorectal cancer. The purpose of this review is to systematically evaluate the molecular pathway and safety of AS-IV in colorectal cancer. 7 databases were queried for Jan 2012-Dec 2022. A total of 37 related articles were retrieved. 8 papers were included to evaluate the role of AS-IV in colorectal cancer and make a review. AS-IV plays vital roles in colorectal cancer, especially in the suppression of proliferation, inducing tumor cell apoptosis, increasing immune function and reducing drug resistance. Furthermore, AS-IV has been proved to regulate many signaling pathways, which are usually affected by most cancers. However, a large-scale and well-designed multicenter randomized controlled study ensures that the safety and optimal dose of AS-IV will be determined in the future.

Lipid levels in the Jiarong Tibetan's diet at high altitudes: a cross-sectional survey.

Despite the ongoing debate on the inconsistent and controversial effects of Tibetan diet on blood lipid levels at high altitude, this cross-sectional study was conducted to analyze the relationship between dietary practices and blood lipid levels among Jiarong Tibetan population. A total of 476 Jiarong Tibetan residents were included, in which basic demographic data, physical activity records, simplified food frequency questionnaire, and biochemical data were collected. Using multivariate logistic regression analysis, the potential associations between the variables were examined, and it was found that fat energy supply ratio increased with the elevation of altitude, while the lipid level showed an inverted U-shaped variation. However, the findings suggested that a diet rich in unsaturated fatty acids might balance the effects of the Tibetan diet on the risk of lipid metabolism disorders. Therefore, it is crucial to concentrate on the fat composition rather than the amount of fat E% intake on the plateau. The results highlighted the importance of investigating the interaction between environment and genes in lipid levels among plateau Tibetan population. However, further large-scale prospective studies are required for better understanding of the complexities involved in dietary practices and their influences on blood lipid levels.

Effect of blood lipid on the change of brachial-ankle pulse wave velocity among prehypertensive population / 中华流行病学杂志

<p><b>OBJECTIVE</b>To explore the effect of blood lipid and lipoprotein ratios on the change of brachial-ankle pulse wave velocity (baPWV) among prehypertensive subjects.</p><p><b>METHODS</b>11 611 subjects with normal blood pressure (BP) were divided into two groups, which was one with optimal blood pressure (BP<120/80 mmHg) and the other with prehypertension (BP:120-139/80-89 mmHg). Height, weight, baPWV, fasting blood-glucose, TC, TG, LDL-C and HDL-C were detected.</p><p><b>RESULTS</b>The abnormal rate of baPWV in prehypertension group was obviously higher than that in the optimal blood pressure group. For optimal blood pressure group, the abnormality of TG, TC, LDL-C, TC/HDL-C as well as LDL-C/HDL-C, caused the increase of baPWV significantly (P < 0.001). For prehypertensive group, the abnormality of TC and LDL-C caused the significant increase of baPWV (P < 0.001). Results from logistic regression analysis showed that except for age, BMI and fasting blood-glucose, TC/HDL-C increasing was the independent risk factor in optimal blood pressure group, while TG increasing was for the prehypertension group.</p><p><b>CONCLUSION</b>With different normal BP level, both abnormality of blood lipid and lipoprotein ratio were the independent risk factors for baPWV increasing.</p>

Characteristics of brachial-ankle pulse wave velocity and its relationship with risk factors of cardiovascular diseases in populations having health check-up programs / 中华流行病学杂志

<p><b>OBJECTIVE</b>To investigate the characteristics of brachial-ankle pulse wave velocity (baPWV)in populations having health check-up and to explore its relationship with risk factors of cardiovascular diseases.</p><p><b>METHODS</b>13 841 people who had health check-up were included and their baPWV were tested by automatic arteriosclerosis measurement system. All people were inquired about their diseases history, while height, weight, body mass index(BMI), blood pressure, fasting blood-glucose as well as serum lipid were also measured.</p><p><b>RESULTS</b>With increasing of age, baPWV were increased both in males and females. The baPWV of male aged less than 60 years was significantly higher than that of female less than 60. Multi-variable regressive analysis showed the age, systolic pressure,BMI, fasting blood-glucose, uric acid and triglyceride were the risk factors of baPWV.</p><p><b>CONCLUSION</b>BaPWV values of health check-up population in Chengdu area demonstrated different characteristics in different age and gender group. Attention should be paid on baPWV measurement among elder people, especially the elder women, in order to prevent cardiovascular events happening in high risk population.</p>
