Objective:To explore the therapeutic and recurrence-preventing effects of Qi-Replenishing and Blood-Activating Formula in rats with acetic acid-induced gastric ulcer.Methods:A total of 138 SD rats were selected to make rat models with gastric ulcer induced by acetic acid(24 rats with sham operation served as sham operation group),and were randomly divided into model group(n=30),western medicine group(n=30),traditional Chinese medicine(TCM) group(n=24) and combination group(combined western medicine and TCM group,n=30).Western medicine group was gavaged with omeprazole in the morning and with iso-volumetric distilled water in the afternoon;TCM group and TCM sham operation group were gavaged with iso-volumetric distilled water in the morning and with Qi-Replenishing and Blood-Activating Formula in the afternoon;combination group was gavaged with omeprazole in the morning and with Qi-Replenishing and Blood-Activating Formula in the afternoon;sham operation group and model group were gavaged with iso-volumetric distilled water both in the morning and afternoon.Ulcer indexes and degree of mucosal degree in rats at different time points after gavage were observed.Twentyeight days after gavage,interleukin(IL)-1β was given to induce ulcer recurrence so as to observe the recurrent severity and rate of ulcer in each group.Results:Compared with model group and western medicine group,treatment in combination group could prominently reduce the ulcer index of rats with peptic ulcer,and increase the healing rate and inhibition rate of peptic ulcer.After IL-1β-induced ulcer recurrence,combination group was significantly superior to model group and western medicine group in ulcer recurrent rate[50%(3/6) vs.100%(6/6)]and severity.Conclusions:Basic acid-suppression therapy combined with Qi-Replenishing and BloodActivating Formula can effectually improve the ulcer healing quality and reduce ulcer recurrence.

Effect of Chinese Herbs for Activating Blood Circulation,Removing Stasis and Supplementing Qi on the Circulating Endothelial Cells in Patients with Unstable Angina Pectoris

Objective: To observe the effect and clinical significance of circulating endothelial cells (CEC) in the pathogenesis of coronary heart disease with unstable angina pectoris (CHD-UAP), and to explore the protective effect of Chinese herbs for activating blood circulation, removing stasis and supplementing Qi (CH) on CHD-UAP patient's CEC. Methods: Sixty patients with diagnosis of CHD-UAP confirmed and differentiated to be Qi-deficiency and blood stasis by TCM were randomly divided into two groups and treated, on the basis of Western drug-therapy, with Tongxinluo capsule (通心络胶囊, TXL) and Huoxue Tongmai capsule (活血通脉胶囊, HXTM) respectively by way of oral taking three times a day, 3 capsules every time, with 1 month as one therapeutic course. The number of CEC in patients' blood circulation was counted before and after treatment. Besides, the number of CEC in 30 healthy persons was also counted for control. Results: The number of CEC in CHD-UAP patients was significantly higher than that in the healthy persons (P<0.01). After the patients were treated with CH, either TXL or HXTM, it significantly decreased (P<0.01)with insignificant difference between the two treated groups. Conclusion: CEC in CHD-UAP patients is severely damaged and endothelial function in disorder, Chinese herbs have protective effect on patients' CEC.

Objective:To systemically review the efficacy and safety about the method of enriching qi,activating blood circulation,clearing away dampness and heat combined with western medicine in the therapy of patients with idiopathy membranous nephropathy(IMN).Methods:We collected the randomized controlled trials(RCTs)of enriching qi,activating blood circulation,clearing away dampness and heat for the treatment of IMN from Pub Med,The Cochrane Library,Medline,China National Knowledge Infrastructure(CNKI),China Biology Medicine disc(CBM),Wanfang Data and Wiper Databases.Bias of risk of retrieval literature was evaluated according to Cochrane Collaboration standard,and Review Manager 5.3 software was used for statistical analysis.Results:Fourteen trials(836 participants)were included in the meta-analysis.This kind of traditional Chinese method combined with western medicine in the treatment of IMN exerted statistical differences in reducing 24-hour urinary protein[WMD=-0.97,95%CI(-1.30,-0.65),Z=5.86(P<0.00001)]and elevating serum albumin[WMD=3.83,95%CI(2.10,5.57),Z=4.33,P<0.0001],lowering serum cholesterol[WMD=-0.82,95%CI(-1.08,-0.56),Z=6.18,P<0.00001],triglycerides[WMD=-0.39,95%CI(-0.67,-0.11),Z=2.77,P=0.006]and reducing the risk of adverse events[OR=0.29,95%CI[0.16,0.50],Z=4.35,P<0.0001]in the patients with IMN as compared with controls.However,there was no statistically significant difference between the method and controls when combining all trials in serum creatinine[WMD=-5.52,95%CI(-18.06,7.03),Z=0.86,P=0.39],when combining all trials in urea nitrogen[WMD=-0.90,95%CI(-2.22,0.41),Z=1.35,P=0.18].Conclusion:The method of enriching qi,activating blood circulation,clearing away dampness and heat combined with western medicine exerts certain advantages and better safety in treating patients with IMN.However,for the inferiority of the included studies,the conclusion still needs high-quality and large-sample prospective randomized controlled trials to verify.

Supplementing Qi and activating blood circulation method to treat vertebrobasilar dolichoectasia with posterior circulatory watershed infarction:a case report of two patients

Vertebrobasilar dolichoectasia(VBD),a rare posterior circulation vascular variant disease,is an important risk factor for many acute cerebrovascular diseases.An insufficient understanding of VBD often leads to misdiagnose.Two cases of VBD that were initially diagnosed as posterior circulation watershed infarction are reported here.Absence of common causes of stroke including hypoperfusion,blood system diseases,carotid and aortic dissection,and eosinophil elevation,the symptoms of the 2 patients met the diagnostic criteria of VBD.Both patients displayed symptoms that were in line with the Traditional Chinese Medicine(TCM)syndrome pattern of"Qi deficiency and blood stasis".Accordingly,they were comprehensively treated with Supplementing Qi and activating blood circulation method.The clinical manifestations of the 2 patients were remarkably improved and no recurrence of watershed infarction was found in a 1-year follow-up.A detailed medical history and laboratory examination are capable of improving diagnostic accuracy of VBD.TCM treatment based on syndrome identification might be a promising candidate for VBD management.

Effects of Chinese herbs capable of replenishing qi, nourishing yin and activating blood circulation and their compatibility on differentially expressed genes of ischemic myocardium

This study was conducted to investigate the effects of Chinese herbs capable of replenishing qi, nourishing yin and activating blood circulation and their compatibility on differentially expressed genes of ischemic myocardium which were selected from differential expression profile we had established before, and to explore the underlying mechanism. The acute myocardial infarction (AMI) model was established by ligating the left anterior descending (LAD) coronary artery, then the model rats were randomly divided into the model group, the Metoprolol group, the replenishing qi nourishing yin (RN) group, the activating blood circulation (AB) group, and the replenishing qi, nourishing yin and activating blood circulation (RA) group. In addition, the normal group and the sham group were set up. The rats of medication groups were administered by intragastric gavage with corresponding drugs on the second day after operations, and the rats of the normal group and the sham group were given normal saline as the same time.Then the ischemic hearts were harvested on the 8th day after operation. The myocardial pathomorphological changes were observed under a light microscope. The mRNA changes of target genes such as COX5a and ATP5e were detected using Realtime fluorescence quantitative PCR (QPCR), and the activities of related enzymes were detected by colorimetric assay. The main results were as follows: the histological changes were observed by HE staining, and cardiocyte swelling, inflammatory cell infiltration and cytolysis were showed in regional ischemic myocardium of the model group, while the pathomorphological changes in all medication groups did not show obvious changes. Two genes related to energy metabolism, COX5a and ATP5e, were selected as the target genes which were downregulated at the mRNA level in the medication groups. The activities of correlative functional enzymes also decreased in the RA group compared to that in the model group accordingly (P<0.05). The results indicated that the abnormal expression of genes involved in energy metabolism pathways could be one of the molecular mechanisms of AMI. The compatibility of Chinese herbs capable of replenishing qi, nourishing yin and activating blood circulation affects the expression of energyrelative gene COX5a, ATP5e, which is probably the mechanism of myocardial preservation, and is more effective than single herb of replenishing qi and nourishing yin or activating blood circulation.

Objective： To investigate the effects of Chinese herbs for supplementing qi, nourishing yin and activating blood circulation on heart function of patients with acute coronary syndrome （ACS） after successful percutaneous coronary intervention （PCI）. Methods： One hundred patients with ACS after successful PCI were randomly assigned to a Western medicine （WM） treatment group （WMG） and a combined treatment group （CMG） treated by Chinese herbs for supplementing qi, nourishing yin and activating blood circulation, besides Western medicine treatment, with 50 cases in each group. Both treatment courses were 6 months. The follow- up was scheduled at baseline, 6 months and 1 year after PCI, and New York Heart Association （NYHA） functional class, Chinese medicine （CM） symptom scores, blood stasis syndrome scores, and major adverse cardiovascular events （MACE） were observed, serum levels of N-terminal pro-brain natriuretic peptide （NT-proBNP） and hyper-sensitivity C-reactive protein （Hs-CRP） were measured, an echocardiogram was conducted to examine left ventricular ejection fraction （LVEF）, left ventricular end-diastolic volume （LVEDV）, left ventricular end-systolic volume （LVESV）, inter-ventricular septal thickness （IVST）, left ventricular posterior wall thickness （LVPWT）, and ventricular wall motion index （VWMI）. Results： Compared with the baseline, LVEF significantly increased （P〈0.01）, and CM symptom scores, blood stasis syndrome scores, VWMI, LVEDV, LVESV, NT-proBNP, and Hs-CRP all decreased （P〈0.01） in both groups at 6 months and at 1 year after PCI. There were no significant differences in all the above parameters at 1 year vs those at 6 months after PCI （P〉0.05）. VWMI, LVEDV, LVESV, NT-proBNP, Hs-CRP, LVEF, and CM symptom and blood stasis syndrome scores were all improved obviously in CMG than those in WMG （P〈0.05 or P〈0.01） at 6 months and at 1 year after PCI. There were no significant differences in NYHA functional class between CMG and WMG at different follow-up timepoints; it was notable that P value was 0.054 when comparing the cases of NYHA functional class between the two groups at 1-year follow-up. During the 1-year follow-up, 3 MACE and 11 MACE occurred in CMG and WMG, respectively; the MACE rate in CMG was lower than that in WMG （6% vs 22%, P〈0.05）. Conclusion： Chinese herbs for supplementing qi, nourishing yin and activating blood circulation could improve heart function, reduce the CM symptom scores and blood stasis syndrome scores, and decrease the incidence of MACE in patients with ACS after successful PCI.

Clinical Study on Effect of Chinese Herbal Medicine for Supplementing Kidney and Qi and Activating Blood Circulation in Treating Intrauterine Growth Retardation of Fetus

Objective: To explore the therapeutic effect and the possible working mechanism in using Chinese herbal medicine (CHM) for supplementing Kidney and Qi, and activating blood circulation in treating intrauterine growth retardation of fetus (IUGR). Methods: Fifty-five cases of IUGR were divided into two groups, 30 cases in the CHM group treated with CHM and the 25 in the control group treated with amino acids. The effect of CHM treatment was observed and compared with that of the control group, normal pregnancy group and non-treated IUGR group. Results: Body weight of the newborns in the CHM was markedly higher than that in the control group. Not only the maternal fundal height (FH) and the abdominal circumference (AC), but also the fetal growth parameters, including biparietal diameter, head circumference (HC), and femur length (FL) in the CHM group increased much faster than those in the control group. After CHM treatment, the maternal serum levels of estriol (E3) and human placental lactogen (hPL) approached to those in the normal pregnancy group, but the control group,in comparison with the normal pregnancy group, was significantly different. The umbilical venous plasma concentration of essential amino acids in both treated groups improved, but the improvement in the CHM group was more significant than that in the control group. No apparent adverse effect of CHM was observed in either mother or fetus.Conclusion: CHM for supplementing Kidney and Qi and activating blood circulation was more effective in improving placental function and enhancing amino acid transportation than amino acid
