ABSTRACT
The wind, phlegm, and blood stasis are important pathogenic factors of cough variant asthma in children, and they are also the pathological products in the occurrence and development of this disease. They have typical pathogenic characteristics. The main pathogenesis characteristics of cough caused by wind, phlegm and blood stasis are as follows that external wind attacks the lungs and induces internal wind, phlegm and dampness accumulates in the lungs, and the lungs fail to declare and descend, and blood stasis obstructs the collaterals and stagnation of Qi. The wind, phlegm, and blood stasis have their own pathogenic characteristics, and their cough-causing also have their own pathogenic characteristics and clinical characteristics. Based on the characteristics of wind, phlegm, and blood stasis, the application of medicine based on the differentiation of symptoms and signs can effectively prevent and treat this disease, and provide theoretical basis and treatment ideas for the treatment of cough variant asthma in children with Chinese medicine.
ABSTRACT
Objective:To systematically evaluate the clinical effect of biliary stent combined with intra-biliary radiofrequency ablation and stent alone in the treatment of malignant obstructive jaundice.Methods:The PubMed, Cochrane library, Embase, HowNet, Wanfang, Weipu were systematically searched, the search time was up to February 2021. To collect and compare the clinical efficacy studies of combined intra-biliary radiofrequency ablation in the treatment of patients with malignant obstructive jaundice before biliary stent placement. After literature screening, data extraction and quality assessment conducted by two independent reviewers. Meta-analysis was performed with the patients' 1-year survival rate, 6-month patency rate after biliary stent operation, and comparative changes in postoperative complications as the main outcome indicators.Results:Finally, 9 studies were included, comprising 2 randomized controlled studies (RCT) and 7 retrospective studies, involving a total of 443 patients, with 211 cases in the biliary stent combined with intra-biliary radiofrequency ablation group and 232 cases in the stent alone group. The results of meta-analysis showed that in two joint groups compared with the stent alone group, in overall analysis, the rate of re-obstruction of the biliary tract decreased 6 months after stenting ( OR=0.24, 95% CI: 0.13-0.42) and 1-year survival rate increased ( OR=3.79, 95% CI: 2.08-6.90), the differences are statistically significant ( P<0.001), there was no statistical difference in the complications ( P=0.13). In ERCP group, the rate of re-obstruction of the biliary tract decreased 6 months after stenting ( OR=0.21, 95% CI: 0.08-0.55), and the 1-year survival rate significant increase ( OR=3.63, 95% CI: 1.76-7.48), the differences are statistically significant ( P<0.01). In PTCD group, the rate of re-obstruction of the biliary tract decreased 6 months after stenting ( OR=0.25, 95% CI: 0.12-0.51), and the 1-year survival rate significant increase ( OR=4.13, 95% CI: 1.42-12.03), the differences are statistically significant ( P<0.01). Conclusion:Compared with the stent-only group, the combined group is safe and effective in treating malignant obstructive jaundice.
ABSTRACT
ObjectiveTo investigate the effect of kaempferol on the proliferation, migration, invasion, and apoptosis of human hepatoma Bel-7402 cells and related molecular mechanism. MethodsHepatoma Bel-7402 cells cultured in vitro were randomly divided into control group and low-, middle-, and high-concentration experimental groups. The experimental groups were treated with low-, middle-, and high-concentration kaempferol (25, 50, and 100 μmol/L), and the control group was treated with an equal volume of dimethyl sulfoxide. CCK-8 assay was used to observe the effect of kaempferol on the viability of Bel-7402 cells; plate colony formation assay was used to evaluate the effect of kaempferol on cell colony formation ability; wound healing assay and Transwell chamber were used to observe the effect of kaempferol on cell migration and invasion; Western blot was used to measure the expression of apoptosis- and cycle-related proteins. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsAfter 24 hours of treatment, the cell viability was 100.00%±2.72% in the control group and 75.70%±2.42%, 62.79%±2.45%, and 43.41%±2.11%, respectively, in the low-, middle-, and high-concentration experimental groups, and compared with the control group, the experimental groups had a significant reduction in cell viability (all P＜0.05). The number of cell colonies was 923.3±35.2 in the control group and 682.7±24.4, 464.0±22.0, and 327.3±14.0, respectively, in the low-, middle-, and high-concentration experimental groups, and compared with the control group, the experimental groups had a significant reduction in cell colony formation ability (all P＜0.05). After 24 hours of treatment, the relative migration rate was 100.00%±1.11% in the control group and 63.33%±1.16%, 51.72%±3.23%, and 37.18%±2.71%, respectively, in the low-, middle-, and high-concentration experimental groups, and the number of transmembrane cells was 212.0±3.0 in the control group and 134.0±2.0, 71.0±2.0, and 34.0±1.0, respectively, in the low-, middle-, and high-concentration experimental groups; compared with the control group, the experimental groups had significant reductions in relative migration rate and number of transmembrane cells (all P＜0.05). After 48 hours of treatment, compared with the control group, the low-, middle-, and high-concentration experimental groups had a significant reduction in the expression of the anti-apoptotic protein Bcl-2 (all P＜0.05), a significant increase in the expression of the pro-apoptotic protein Bax (all P＜0.05), and a significant reduction in the expression of C＜italic/＞yclinD1 (all P＜005). ConclusionKaempferol can inhibit the proliferation, migration, and invasion of human hepatoma Bel-7402 cells and promote the apoptosis of such cells, possibly by regulating the apoptosis proteins Bax and Bcl-2 and downregulating the expression of CyclinD1.
