运动调节代谢综合征患者脂肪因子的研究进展

代谢综合征是一组多种代谢性疾病的危险因素,包括中心性肥胖、血脂异常、糖代谢紊乱、高血压等在同一个体聚集的临床综合征。代谢综合征的核心成分是脂肪组织,脂肪组织除了作为能量储存器官外,还可以被视为一个动态的、复杂的内分泌器官,产生和分泌多种脂肪因子。运动对人体的新陈代谢是有益的,但运动作用于代谢综合征的机制还不完全清楚,可能与能量消耗和脂肪因子的变化有关。因此,该文选择一些代谢综合征相关经典脂肪因子,对运动调节脂肪因子可能的机制进行综述,为治疗胰岛素抵抗和肥胖提供新的思路。

Effect of Shenqiyixin prescription on myocardial energy metabolism in patients with chronic heart failure

Objective:To observe the heart function、MEE and serum FFA of Shenqiyixin prescription for heart qi(yang)deficiency with blood stasis and fluid retention type of chronic heart failure patients,to evaluate the clinical efficacy and safety.Methods:64 cases with chronic heart failure of heart qi(yang)deficiency with blood stasis and fluid retention were randomly divided into two groups,3 cases were excluded,31 cases in the control group and 30 cases in the treatment group.The control group was treated with western medicine,and the treatment group was treated with Shenqiyixin prescription additionally.The course of treatment was 3 weeks.Observe the changes of TCM syndrome score,6MWD,LVEF,cESS,MEE,serum NTproBNP,serum FFA and safety indexes of each group before and after treatment.Results:after treatment,the TCM Syndromes of each group were improved.The total effective rate of the treatment group was 93.33%,and the control group was 83.87%.The treatment group was more effective(P<0.05).After treatment,the TCM syndrome score,cESS,MEE,NTproBNP and FFA of each group were decreased,6MWD and LVEF were increased(P<0.05),and the treatment group was superior to the control group(P<0.05).Conclusion:Shenqiyixin prescription can improve the TCM syndrome and heart function in patients with chronic heart failure of heart qi(yang)deficiency with blood stasis and fluid retention,at the same time,it can reduce the level of MEE and serum FFA in patients with heart failure.

Meta-analysis of randomized controlled trials of traditional Chinese medicine in the treatment of obstructive sleep apnea syndrome

Objective:Though Chinese medicine(CM)has showed its clinical efficacy for the treatment of obstructive sleep apnea(OSA)in China,no systematic reviews or meta-analyses provide evidences for its therapeutic effects on OSA and the long-term safety.The aim of the present study is to evaluate the effectiveness and safety of CM on OSA using meta-analysis.Methods:We used search items of"Chinese Medicine"AND"obstructive sleep apnea"to retrieve the randomized control trials(RCTs)of CM treatments for OSA in PubMed,Embase,Cochrane Library,China National Knowledge Infrastructure(CNKI),VIP database,and Wanfang database from their respective inception dates to December 2019.Only RCTs of CM therapy versus no treatment which could be quantitatively synthesized were included.Finally,20 studies representing 1,297 participants were included after extraction.Two investigators independently extracted and analyzed the data using RevMan5.3 software.Results:The treatment group using CM decoctions or CM granules presented significantly ameliorative effects on apnoea-hypopnoea index(AHI)compared with the control group(MD:-2.58,95%CI:-3.59 to-1.56,P<0.00001 and MD:-5.47,95%CI:-6.75 to-4.19,P<0.00001,respectively)in the sensitivity analysis.However,there were non significant differences in the duration of treatment between subgroups,indicating that the duration of treatment has no impacts on the therapeutic effects on AHI.CM granules also showed significantly ameliorative effects on the lowest nocturnal oxygen saturation(LSaO2)(MD:2.76,95%CI:1.85 to 3.68,P<0.00001).CM decoctions exhibited significantly improved Epworth Sleepiness Scale(ESS)scores compared with the control group in a sensitivity analysis(MD:-1.50,95%CI:-2.13 to-0.88,P<0.00001).CM granules showed a better improvement of ESS than the control group(MD:-1.35,95%CI:-1.92 to-0.78,P<0.00001).Mild adverse reactions occurred only in five patients and disappeared without special treatment.Conclusion:This study showed favorable therapeutic efficacy of CM on OSA.However,in consideration of the low methodological quality of the included RCTs,more rigorous designed,large sample size RCTs are recommended for providing more high-quality evidences.

Proteomics analysis of Huanglian Wendan decoction drug-containing serum on insulin resistance in 3T3-L1 cell

Objective:To explore possible mechanisms of Huanglian Wendan decoction drug-containing serum to improve insulin resistance.Method: 3T3-L1 fibroblasts were divided into control group, model group and TCM group. 3T3-L1 fibroblasts in model group and TCM group were induced to differentiation, and the 3T3-L1 adipocyte model of insulin resistance was constructed. The control group and model group were given normal serum stimulation, while the TCM group is treated with drug-containing serum. Finally, proceed bioinformatics analysis of the acquired differential expression protein by using TMT marking, liquid chromatography-mass (LC-MS) spectrometry, GO analysis and KEGG pathway analysis.Results:4982 proteins are identified in three groups of samples in this experiment, 4238 of them contain quantitative information. 210 up-regulate and 399 down-regulate proteins exist in model group and control group;221 up-regulate and 98 down-regulate ones are identified in TCM group and control group;310 up-regulate and 142 down-regulate proteins come to light with TCM group and control group. The result shows that the differentially expressed proteins were mainly distributed in s GO terms, such as DNA replication, nucleoplasm and protein binding of TCM group and control group. KEGG pathway enrichment analysis shows that, differentially expressed up-regulate proteins were enriched in 10 pathways, for instance DNA replication, cell cycle and mismatch repair, etc. Besides, differentially expressed down-regulate proteins were enriched in 25 pathways, enriched pathways are peroxisome, fatty acid degradation and metabolism process, etc.Conclusion: It is clear that Huanglian Wendan decoction drug-containing serum could improve insulin resistance by multi-targeting, multi-pathway synergy, and overall regulation.
