Effect of Chinese Herbal Medicine for Nourishing Yin,Supplementing Qi,and Activating Blood on the Th1/Th2 Immune Balance in Peripheral Blood in Patients with Primary Sjogren's Syndrome

Objective： To observe the effect of Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood on the expression of interferen- γ （IFN-γ,）/interleukin-4 （IL-4） in peripheral blood and disease activity in primary Sjogren＇s syndrome （pSS） patients, and to study the relationship between the immune balance of Th1/Th2 and the disease activity. Methods： A total of 66 pSS patients were randomized with tossing coins method into two groups： the integrative therapy group （34 cases） and the control group （32 cases）; and 28 healthy subjects were taken as the normal group. The integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets and the control group was treated with hydroxychloroquine sulfate tablets. The treatment course was 3 months for both groups. The levels of serum immunoglobulin G （IgG）, erythrocyte sedimentation rate （ESR）, IFN-γand IL-4 in peripheral blood were measured before and after treatment. Results： Compared with the normal group, the levels of IgG, ESR, IFN- γ and IL-4 were significantly increased in pSS patients （P〈0.05）. Remarkably, after 3 months of treatment, these levels were dramatically decreased in both the integrative therapy group and the control group, although still higher than the normal group. The levels of IgG, ESR, IFN- and IL-4 in the integrative therapy group were lower than the control group and the same group before treatment （P〈0.05）. The ratio of IFN-γ/IL-4 also significantly decreased after treatment. Moreover, the level of IFN- γ, and the ratio of IFN- γ/IL-4 in the integrative theraphy group were significantly lower than the control group （P〈0.05）. For all patients the ratio of IFN-γ/IL-4 before and after treatment was positive correlated with the levels of IgG and ESR. Conclusion： Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood can alleviate the disease activity of pSS by regulating the immune balance of Th1/Th2.

Effect of Chinese Herbal Medicines for Nourishing Yin,Supplementing Qi,and Activating Blood on Reproductive Endocrine Activity and Immune Functions in Patients with Primary Sjogren's Syndrome

ABSTRACT Objective： To investigate the effect of Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood on the reproductive endocrine-immune network and its mechanisms in patients with primary Sjogren＇s syndrome （pSS）. Methods： Seventy pSS patients were randomly assigned to two groups using a randomized digital table： the integrative therapy group （36 cases） and the control group （34 cases）. Thirty healthy subjects were taken as a normal group. The control group was treated with hydroxychloroquine sulfate tablets alone, and the integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets. The treatment course was 6 months for both groups. Before and after treatment, serum estradiol （E2）, testosterone （T）, luteinizing hormone （LH）, prolactin （PRL） by radioimmunoassay and immunoglobulin （IgG） by immunodiffusion, erythrocyte sedimentation rate （ESR） by Westergren, interferon-γ （IFN-γ） and interleukin-4 （IL-4） by enzyme linked immunosorbent assay were determined. Results： E2 and T levels in all patients were lower than those of normal subjects before treatment （P〈0.05） and were increased significantly after 6-month treatment （P〈0.05）. ESR, FSH, LH, IgG, IFN - γ, IL - 4 and ratios of E2/T, and IFN --γ/IL in the patients were higher than those of normal subjects before the treatments （P〈0.05）, and were reduced significantly after the treatments （P〈0.05）. The T and IFN -γ levels and E2/T ratio in the patients treated with integrative therapy were reduced significantly compared with the control group （P〈0.05）. However, the PRL levels before and after treatment were not significantly changed in the two groups （P〉0.05）. The ratios of E2/T and IFN -γ/IL-4, and levels of IgG and ESR were positively correlated before and after treatment （P〈0.05）. Conclusions： The ratios of E2/T and IFN - γ/ IL-4 might be used as indicators of pSS activity. Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with Western medicine could improve the therapeutic effect by regulating the reproductive endocrine-immune network in pSS patients.

Protective Effect of Chinese Herbs for Supplementing Qi,Nourishing Yin and Activating Blood Circulation on Heart Function of Patients with Acute Coronary Syndrome after Percutaneous Coronary Intervention

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.

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.

基于“二阳结谓之消”探讨糖尿病性便秘病机及防治策略

“二阳结谓之消”语出《素问·阴阳别论篇》,是认识糖尿病性便秘的早期记载,但目前学界多据此仅从二阳(足阳明胃经、手阳明大肠经)结滞化热来解释消渴期发生便秘的病机,存在一定局限性。通过考究发现“二阳”并不单指手足阳明经脉或胃肠二腑,而是包括胃、大肠二腑及手足阳明经脉;“结”也并不完全指结热这一病邪,而是指病邪胶结难解、疾病难以治愈的程度,并且“二阳”之热易伤血脉,造成络脉瘀滞。基于对“二阳结谓之消”的重新理解,笔者认为糖尿病性便秘在糖尿病期以“热伤气阴”为主要病机,糖尿病并发症期以热伤血络、血脉瘀滞为主要病机。治疗方面,糖尿病期以清热益气养阴为本,糖尿病并发症期以活血化瘀为核心,此外还需重视体质从化,全面把握糖尿病性便秘的诊治。
