Meta-analysis for Qishen Yiqi Dropping Pills in Treatment of Chronic Heart Failure with Syndrome of Qi Deficiency and Blood Stasis / 中国实验方剂学杂志

Objective: To evaluate the efficacy and safety of Qishen Yiqi dropping pills in the treatment of chronic heart failure. Method: Eight databases were searched at home and abroad, and the randomized controlled trials of Qishen Yiqi dropping pills in the treatment of chronic heart failure were screened. Literature quality of the included studies was evaluated by the bias risk assessment tool of Cochrane collaboration network, and the Meta-analysis was performed by RevMan 5.3 software. Result: A total of 606 related literature were retrieved, and 11 studies were eventually included, involving 931 patients. The quality of the included literature was generally low. Meta-analysis results showed that efficacy of Qishen Yiqi dropping pills combined with conventional western medicine was better than conventional western medicine alone in improving B-type natriuretic peptide[weighted mean difference (WMD)=-29.47, 95% confidence interval (CI) (-37.29,-21.64), PPPP=0.005], 6-minute walk test[WMD=50.13, 95%CI (22.32, 77.93), P=0.000 4]. In terms of safety indicators, one study intended to observe safety indicators, but it was not reported in the actual literature, and the remaining studies did not find adverse reactions of Qishen Yiqi dropping pills combined with conventional western medicine. Conclusion: The results of this study support the clinical use of Qishen Yiqi dropping pills combined with conventional western medicine in the treatment of chronic heart failure, but in view of the limitations in the quantity and quality of clinical studies, the positive results are only used as a reminder and reference for clinical diagnosis and treatment. In the future, more high-quality researches are needed to further confirm its efficacy.

Intestinal absorption and metabolism of Puerariae Lobatae Radix decoction by in situ closed-loop method / 中国中药杂志

Biopharmaceutics classification system of Chinese materia medica (CMMBCS) emphasizes characteristic of the multi-component environment based on the drug solubility and permeability. In this study, the in situ closed-loop method combined with LC-MS technique was utilized to study the intestinal absorption and metabolism of Puerariae Lobatae Radix decoction (PLRD), providing selection basis for intestinal permeability components in CMMBCS. A total of 36 components were identified from PLRD. Among them, 17 components could be detected in the plasma sample, indicating that 17 components could be absorbed into blood, so these 17 components could be used as intestinal permeability evaluation components in CMMBCS. The other 19 components were not detected in the plasma sample, suggesting that they may not be absorbed or metabolized by the gut wall enzymes.

A correlation research on Chinese medical syndromes of chronic heart failure and various complications / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the correlation between various complications of chronic heart failure (CHF) patients and Chinese medical syndromes, thus indicating distribution laws of Chinese medical syndromes in various complications of CHF patients.</p><p><b>METHODS</b>Chinese medical syndrome typing was performed in 630 CHF patients by cross-sectional study of the demographic data, history of present diseases, related information on Chinese medical four diagnostic methods, and the distribution of complications. Logistic regression analysis was used to determine the correlation of various complications of CHF patients and Chinese medical syndromes.</p><p><b>RESULTS</b>In this study, recruited were common complications such as hypertension, diabetes, arrhythmia, hyperlipemia, and cerebral vascular accident, and so on. Main syndromes were sequenced as qi deficiency syndrome, blood stasis syndrome, water retention syndrome, yin deficiency syndrome, phlegm turbid syndrome, yang deficiency syndrome. Results of Logistic regression analysis indicated that correlation existed between common complications and Chinese medical syndromes. In CHF complicated hypertension patients, Logistic regression analysis showed qi deficiency syndrome and yang deficiency syndrome were negatively correlated with hypertension (P < 0.05). In CHF complicated diabetes patients, Logistic regression analysis showed phlegm turbid syndrome and water retention syndrome were positively correlated with diabetes (P < 0.05). In CHF complicated arrhythmia patients, there was no statistical difference in the distribution of each syndrome (P > 0.05). In CHF complicated hyperlipemia patients, Logistic regression analysis showed qi deficiency syndrome and water retention syndrome were negatively correlated with hyperlipemia (P < 0.05), while blood stasis syndrome, yin deficiency syndrome, and phlegm turbid syndrome were positively correlated with hyperlipemia (P < 0.01). In CHF complicated cerebral vascular accident patients, Logistic regression analysis showed qi deficiency syndrome and yang deficiency syndrome were negatively correlated with cerebral vascular accident (P < 0.01, P < 0.05).</p><p><b>CONCLUSIONS</b>There existed certain correlations between complications of CHF and the distribution of main Chinese medical syndromes. It could be used as guidance for treating CHF and its various complications by Chinese medicine and pharmacy.</p>

Gel electrophoresis analysis on plasma differential protein in patients with unstable angina of blood-stasis pattern / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To seek the plasma differential proteins in patients with unstable angina of blood-stasis pattern (UA-BSS) for exploring the proteomic specialty in them by way of two-dimensional difference gel electrophoresis (DIGE) detection on plasma of patients and healthy persons.</p><p><b>METHODS</b>Using DIGE and tandem mass spectrometry, comparative proteomic study was conducted on the plasma of 12 UA patients of qi-deficiency and blood-stasis pattern (UA-QBS), 12 UA patients of phlegm-stasis cross-blocking pattern (UA-PSS) and 12 healthy volunteers.</p><p><b>RESULTS</b>Preliminary results showed that Haptoglobin beta chain, DBP, HBB, HBA, Transthyretin, ApoA- I, ApoA-IV were significantly differentially expressed in both patterns, while Haptoglobin alpha1 chain, alpha-1-acid glycoprotein, ApoC-III, ApoA-II, ApoC-II, ApoJ, and Haptoglobin alpha 2 chain were only seen differentially expressed in the UA-PSS patients, alpha1-antitrypsin, Fibrinogen gamma chain, and Fibrin beta were only seen differentially expressed in UA-QBS patients.</p><p><b>CONCLUSION</b>The common proteomics characteristics of patients of QBS and PSS patterns may be correlated with inflammatory reaction and metabolic disturbance (including blood lipid and blood oxygen).</p>

Study on proteomic specificity of unstable angina with qi deficiency and blood stasis syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To seek the special plasma molecule in unstable angina (UA) patients of qi deficiency and blood stasis syndrome (QDBS) and method for explore the proteomic specificity of the disease.</p><p><b>METHODS</b>LC-MS(E) analysis was performed in UA patients of QDBS or non-QDBS and in healthy persons after the 6 proteins with optimal abundance in plasma being removed by polyclonal antibody affinity column (product of Agilent Co. USA).</p><p><b>RESULTS</b>Actin were found only expressed, and FN, ApoH and ANXA6 were found highly expressed in plasma of patients with UA-QDBS, suggesting they might be the special molecules for the disease. Moreover, as compared with health persons, SAA, CP, MYH11 and C6 showed high expression, and the 6 proteins, e.g. A1BG, ApoA4, GSN, HBB, HBD and TF, showed low expression in the plasma of UA-QDBS patients.</p><p><b>CONCLUSION</b>UA-QDBS might belong to a kind inflammatory reaction. There are simultaneous existence of myocardial injury, blood coagulation factor abnormality, lipid metabolic disorder and oxygen transport obstacle in patients of UA-QDBS, they influence and interact mutually. The newly discovered differential proteins might provide clues for studying or discovering new protein targets of angina relieving drugs. The new technique of label free quantitative proteomics is an efficient method for bio-marker research of diseases and syndromes.</p>
