Tong-xin-luo capsule inhibits left ventricular remodeling in spontaneously hypertensive rats by enhancing PPAR-gamma expression and suppressing NF-kappaB activity / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Tong-xin-luo capsule (TXL), used as a traditional Chinese herb, offeres a therapeutic potential for treatment of cardiovascular diseases. It has been shown to exert a variety of pharmacological effects, including antihypertensive effects, and is able to improve ventricular remodeling. However, the mechanisms of its action are not completely understood. The aim of this study was to evaluate the molecular mechanisms of Tong-xin-luo capsule on left ventricular remodeling in spontaneously hypertensive rats (SHR).</p><p><b>METHODS</b>Sixteen eight-week-old SHRs were randomized into an SHR group (n = 8) and a TXL group (n = 8) that were given Tong-xin-luo capsule (1.5 mg x kg(-1) x d(-1)). Eight Wistar Kyoto (WKY) rats fed with 0.9% NaCl served as the control group (WKY group). Systolic blood pressure (BP), body weight and heart rate were monitored once every two weeks. Ventricular remodeling was detected by histopathological examination. Nuclear factor kappa B P65 (NF-kappaB P65) and peroxisome proliferators activated receptor gamma (PPAR-gamma) protein and phosphorylated inhibitor kappa alpha (IkappaBalpha) protein were detected by immunohistochemistry and western blot respectively. The physical interaction of the P65-P50 heterodimer with IkappaBalpha and NF-kappaB were measured by co-immunoprecipitation. PPAR-gamma mRNA, collagen I mRNA and collagen III mRNA were measured by real-time PCR.</p><p><b>RESULTS</b>TXL inhibited NF-kappaB P65 expression and ventricular remodeling and suppressed the activation of NF-kappaB compared with the SHR group (P < 0.01, P < 0.05). TXL reduced IkappaBalpha phosphorylation, increased expression of PPAR-gamma protein and enhanced the physical interaction of the P65-P50 heterodimer with IkappaBalpha. The mRNA expression of PPAR-gamma was enhanced but the mRNA expression of collagen I mRNA and collagen I mRNA were suppressed by TXL.</p><p><b>CONCLUSIONS</b>In spontaneously hypertensive rats, TXL could inhibit ventricular remodeling induced by hypertension, and the inhibitory effect might be associated with the process of TXL increasing the expression of PPAR-gamma that could result in the inhibition of the activation of NF-kappaB.</p>

Clinical observation of daidzein intervention on serum inflammatory factors in senile patients with coronary heart disease / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of daidzein on serum inflammatory factors of senile patients with coronary heart disease (CHD).</p><p><b>METHODS</b>Forty senile patients with CHD were randomly assigned into the control group and the daidzein group, 20 in each group. Patients in both groups were treated with conventional medicine, while those in the daidzein group were given daidzein Tablets additionally for 6 weeks. The levels of resting heart rate (RHR), blood pressure (BP), fasting plasma glucose (FPG), blood lipids and inflammatory factors, including hsCRP, IL-6 and TNF-alpha, were measured before and after treatment.</p><p><b>RESULTS</b>In the control group, the levels of RHR, BP and hsCRP changed after conventional medicinal treatment (P < 0.05 or P < 0.01) but other parameters unchanged (P > 0.05). While in the daidzein group, all the parameters measured were decreased in different degrees after 6 weeks treatment (P < 0.05 or P < 0.01), and also showed significant difference as compared with those in the control group respectively (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>Daidzein can effectively decrease the levels serum inflammatory factors in senile patients with CHD, the fact proved that isoflavone has anti-inflammatory effect in patients with coronary atherosclerosis.</p>

Effects of Quyu Xiaoban Capsule on vascular endothelial function in patients with atherosclerosis / 中国结合医学杂志

<p><b>OBJECTIVE</b>To evaluate the therapeutic effects of Quyu Xiaoban Capsule (QYXBC) on endothelial dependent vascular relaxation (EDVR) function in patients with atherosclerosis (AS) with ultrasonic technique.</p><p><b>METHODS</b>Tested were the endothelial function and blood lipids of 42 patients with AS in the treated group and 30 healthy volunteers in the control group. And re-examination of these parameters was carried out on the AS patients after they had been treated with QYXBC for 10 months.</p><p><b>RESULTS</b>Before treatment, the reactive hyperemia induced changes in artery diameter in the treated group was significantly lower than that in the control group (P < 0.01), while insignificant difference was found between the two groups in response to nitroglycerin. In the treated group after treatment, with D%-R improved significantly (P < 0.01), total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) decreased by 16.3%, 5.6%, 10.2% respectively and high-density lipoprotein cholesterol (HDL-C) increased by 7.5%. EDVR was correlated negatively with the serum TC, LDL-C concentrations and the baseline brachial diameter (D(0)) (r = -0.41, -0.66, -0.59, respectively, all P < 0.01), but correlated positively with HDL-C (r = 0.62, P < 0.05). The ameliorative extent of EDVR was correlated positively to the decreased magnitude of TC and LDL-C concentrations (r = 0.67, 0.59, both P < 0.01).</p><p><b>CONCLUSION</b>QYXBC can lower the level of blood lipids and improve significantly EDVR function.</p>

Primary observing pulmonary function variety following three-dimensional conformal radiation therapy of Ⅲ phase non-small cell lung cancer / 中华放射肿瘤学杂志

Objective To explore the pulmonary function,DVH and radiation pneumonitis after three-dimensional conformal radiation treatment ofⅢphase non-small-cell lung cancer.Methods 71 pa- tients (male 52,female 19,median age 63,KPS≥80) were evaluated by pulmonary function tests before radiotherapy and in M1 and M3 after radiotherapy respectively.After 3 months of follow-up time,it reviewed the appearance and grade of radiation pneumonitis.Then V_(20),V_(30) and MLD were worked out from dose vol- ume histogram.Results All patients completed radiotherapy,and total dose was 66-70 Gy.FVC (L), FEV1 (L) and CLCO were (2.58?0.65) L,(1.85?0.58) L and (15.15?4.65)ml/(min)before radio- therapy,with (2.96?0.76) L,(2.13?0.65) L and (14.71?3.92) ml/(min) in Ml after radiotherapy, with (2.65?0.61) L,(1.92?0.52) L and (13.15?3.71)ml/(min)in M3 after radiotherapy.The ac- cidence of radiation pneumonitis was 30%,moderate and severe radiation pneumonitis was 7%.With V_(20), V_(30) and MLD increasing,the grade of radiation pneumonitis was increasing.V_(20),V_(30) and MLD were related to the change in CLCO value among before,M1 and M3 after radiotherapy,and the correlation coefficient was more than 0.2.Conclusions There is a relationship in the pulmonary function,DVH and radiation pneu- monitis surely.The change in C_LCO value between before radiotherapy and M1 after radiotherapy could pre- dict the radiation pneumonitis.V_(20),V_(30) and MLD are not only correlated to radiation pneumonitis evidently but the change in FEV_1 and C_LCO after radiotherapy.
