Effects of Xuezhikang Capsule(血脂康胶囊) on Blood Lipids,Platelet Activation and Coagulation-Fibrinolysis Activity in Patients with Hyperlipidemia

Objective: To investigate the effects of Xuezhikang capsule (XZK, 血脂康胶囊) on blood lipids level, platelet activation and coagulation-fibrinolysis activity in patients with hyerlipidemia. Methods:Seventy-six patients of hyperlipidemia were randomly divided into two groups, the XZK group (n = 38) treated with XZK 600mg, taken two times per day and the Simvastatin (SIM) group (n = 38) treated with SIM 20mg per day, with the treatment lasting 8 weeks for both groups. Levels of fasting serum lipids, including total cholesterol (TC), triglyceride (TG), high and low density l ipoprotein cholesterol (HDL-C and LDL-C),plasma GMP-140, fibrinogen (FIB), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAl-) and prothrombin time (PT) were all measured before and 8 weeks after treatment. Data were compared before and after treatment and also compared with those measured in 20 healthy subjects of control. Results: Before treantment the levels of TC, TG and LDL-C were obviously higher and HDL-C level was significantly lower in hyperlipidemia patients than those in healthy subjects ( P＜0.05 or P＜0.01). After 4-8 weeks of XZK treatment, the levels of TC, TG, LDL-C and FIB and activities of GMP-140 and PAl-1 were obviously lowered (P＜0.05 or P＜0.01). But in the SIM group there was no obvious change in FIB (P＞0.05), instead it showed obvious increase of HDL-C and decrease of TC and LDL-C after treatment ( P＜0.05 or P＜0.01). Conclusion: XZK could inhibit platelet activity and improve coagulation-fibrinolysis function, besides its lipids lowering effect.     

Effects of Tongguan Capsule(通冠胶囊)on Post-myocardial Infarction Ventricular Remodeling and Cardiac Function in Rats

<正>Objective:To observe the effects of Tongguan Capsule(通冠胶囊,TGC) on post-myocardial infarction ventricular remodeling and heart function in rats.Methods:A rat model of acute myocardial infarction (AMI) was established by coronary ligation.Experimental rats were randomized to 4 groups including three model groups(Group A:captopril 5 mg/kg·day,n=7;Group B:TGC 10 g/kg·day,n=7;and Group C:placebo, n=8),and a sham-control group(Group D:blank control,n=6).Animals were treated for 4 weeks.The cardiac function of rats was assessed at the end of the experiment based on left ventricular ejection fraction(LVEF) and left ventricular short axis fractional shortening(LVFS) detected by colored echocardiography;meanwhile, the condition of ventricular remodeling was observed through the levels of left ventricular mass(LVM),plasma aldosterone(ALD),myocardial angiotensinⅡ(AngⅡ) and myocardial collagen measurements.Results:At the end of the experiment,LVEF and LVFS in Group A and B were improved significantly,while those in Group C were unchanged,the LVEF in Group A,B,C,and D was 0.57±0.46,0.61±0.08,0.36±0.55 and 0.76±0.02,respectively;and their LVFS was 0.31±0.52,0.34±0.04,0.23±0.57 and 0.45±0.03,respectively.The difference was statistically significant when comparing the two indexes in Group A and B with those in Group C and D(P0.05).LVM,levels of plasma ALD and myocardial AngⅡwere lower in Group A and B than in Group C,but a comparison between Group A and B showed an insignificant difference in lowering LVM and ALD,while the lowering of AngⅡwas more significant in Group B than in Group A(754.7±18.7 pg/mL vs 952.6±17.6 pg/ mL,P0.05).Morphological examination showed that in Group A and B the swollen myocardial cells had shrunk, with regularly arranged myocardial fibers and decreased collagen proliferation,but the improvements in Group B were more significant.Conclusion:TGC could markedly improve the post-infarction ventricular remodeling and cardiac function in rats,showing that the efficacy was better than or equal to that of captopril.     

Effects of Jinmaitong Capsule (筋脉通胶囊) on Ciliary Neurotrophic Factor in Sciatic Nerves of Diabetes Mellitus Rats

Objective:To study the effects of the Chinese medicine Jinmaitong Capsule(筋脉通胶囊,JMT) on the pathomorphology of sciatic nerves,ciliary neurotrophic factor(CNTF),and the mRNA expressions of CNTF in rats with streptozotocin-induced diabetes mellitus(STZ-DM).Methods:The animal model was established by one time intraperitoneal injection of streptozotocin.The rats were simply divided by random into 5 groups including model group,low-dose JMT group(JL),medium-dose JMT group(JM),high-dose JMT group(JH) and neurotropin group.For each of the above 5 groups,a group of 10 normal Wistar rats matched in body weight,age and gender were set as normal group.Intragastric administrations were started after the animal model established.The JL group were administered with five times the JMT dose recommended for a human adult;the JM group were administered with ten times the JMT dose recommended for a human adult;the JH group were administered with twenty times the JMT dose recommended for a human adult.The neurotropin group was administered with ten times the neurotropin dose recommended for a human adult.All rats were given intragastric administration for 16 weeks and then killed.In the 4th,8th,12th,16th week,body weight and blood glucose level were detected before and after the intervention.The morphologic changes of the sciatic nerves were observed by optical microscope and transmission electron microscope.The CNTFmRNA expressions were detected by real-time fluorescent quantitative polymerase chain protein,and the CNTF protein expressions were detected by immunohistochemical method.Results:The blood glucose levels of the STZ-DM rats were much higher than normal group(P<0.01),and there was no apparent difference between any treatment groups and the model group(P>0.05).Before and after the intervention in the 4th, 8th,12th,16th week,there were no significant differences in the body weight among all the groups(P>0.05). The sciatic nerves of STZ-DM rats might have pathomorphological changes in axons,myelin sheaths,and interstitium.The levels of CNTF and CNTF-mRNA expressions in the STZ-DM rats were both significantly decreased(P<0.01).The sciatic nerves of STZ-DM rats might have pathomorphological changes in axons, myelin sheaths,and interstitium.Conclusion:JMT could improve the pathomorphology of sciatic nerves by increasing CNTF’s and CNTF-mRNA expressions in sciatic nerve tissues,and promote the repair and regeneration of damaged nerve fibers.

Effects of Tetrandrine on Rabbit Platelet Morphology and Aggregation in vitro

Using turbidimetry and electronmicroscopy,we examined the effects oftetrandrine (Tet) on the aggregation and morphological changes of rabbit platelets.It wasfound that Tet could markedly inhibit the platelet aggregation induced by ADP,collagenand arachidonic acid (AA) in a dose-dependent manner.The IC_(50) (50% inhibitoryconcentration) was 38.9,30.3 and 44.3μg/ml respectively.The platelets pretreated with Tetcould not be activated by collagen,their morphological changes and granule release didn'toccur and their normal structure was well preserved.In addition,dipyridamole couldenhance the inhibition of Tet on platelet aggregation,while increased extracellular calciumcould weaken this inhibition.     

Effects of Combined Therapy of Xuezhikang Capsule(血脂康胶囊)and Valsartan on Hypertensive Left Ventricular Hypertrophy and Heart Rate Turbulence

<正>Objective:To observe the effect of combined therapy with Xuezhikang Capsule(血脂康胶囊,XZK) and Valsartan on left ventricular hypertrophy(LVH) and heart rate turbulence(HRT) in hypertensive patients. Methods:Ninety primary hypertensive patients with LVH were randomly assigned to three groups.Basic treatment,including aspirin,β-blockers,calcium antagonists,etc.were administered to all patients.Additionally, Valsartan(VS,80 mg once a day) was given to the 30 patients in the VS group.Valsartan(in the same dosage) and XZK(600 mg,twice a day) were given to the 32 patients in the Chinese medicine(CM) group,while none was given to the 28 patients in the control group.The therapeutic course lasted for 24 months.Changes in left ventricular mass index(LVMI) measured by cardiac ultrasonic indices,HRT parameters,including the original heart rate(TO) and slope coefficient(TS),systolic and diastolic blood pressures(SBP and DBP),as well as blood cholesterol level(TC) were measured before and after treatment.Results:After treatment,TO and LVMI were lowered,while TS increased in both the VS group and the CM group(P0.01),but changed insignificantly in the control group.Significant differences between the CM group and the control group were shown in terms of TO,LVMI,SBP,DBP and TS(P0.01);and between the CM group and the VS group in terms of TO,LVMI and TS(P0.01).Moreover,HRT parameters showed an evident correlation with LVMI(r=0.519-0.635,P0.01). Conclusion:Combined therapy with XZK and Valsartan can improve hypertensive LVH and HRT parameters, and lessen the damage on the autonomous nervous system.

Objective:To confirm the efficacy and safety of Jitongning Capsule(脊痛宁胶囊) in the treatment of ankylosing spondylitis(AS).Methods:A total of 120 AS patients with early-intermediate were randomly and equally assigned to Jitongning Capsule group and sulfasalazine group.Jitongning Capsule was orally taken 4.5 g per day and sulfasalazine was orally taken 2 g daily for 12 months.The primary endpoint was the proportion of patients achieving the Assessment in Ankylosing Spondylitis 20(ASAS 20),secondary end points included Bath Ankylosing Spondylitis Disease Activity Index(BASDAI),Bath Ankylosing Spondylitis Functional Index(BASFI), Bath Ankylosing Spondylitis Metrology Index(BASMI),patient’s global assessment by VAS rating,spinal pain, general pain and night pain,erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP).Tumor necrosis factor-α(TNF-α),interferon-γ(IFN-γ) and interleukin-4(IL-4) in the peripheral blood mononuclear cells (PBMC) of AS patients were measured.Results:A total of 111 patients completed the study.There were 58 patients in Jitongning group and 53 patients in sulfasalazine group.Both drugs showed mild and occasional side effects.After treated by Jitongning Capsule and sulfasalazine,the proportion of ASAS20 responders at 12 month was 72.41%(42/58) and 67.92%(36/53) respectively.Both Jitongning Capsule and sulfasalazine treatment induced significant decrease in the proportion of CD4~+T cell and CD8~+T cell expressing TNF-αand IFN-γat 12-month of treatment compared with baseline values(P<0.05).Conclusion:Jitongning Capsule are effective in a setting close to real-life medical care with a sustained improvement in signs and symptoms of AS,and reduce cytokine levels in PBMC.It showed comparable effects to sulfasalazine.     

Effect of resveratrol on platelet aggregation in vivo and in vitro

Objective Low or moderate consumption of red wine has a greater benefit than the consumpti on of other beverages in the prevention of atherosclerosis and coronary heart di sease and this is increasingly attributed to the polyphenol compounds in red win e, such as resveratrol. In the present study, we investigated the effect of res veratrol on platelet aggregation in vitro and in vivo. Methods Platelet aggregation in rabbits and normal subjects was measured using Born’s me thod. Results Resveratrol, at 10-1000 μmol/L, significantly inhibited platelet aggregation i n vitro induced by collagen, thrombin, and ADP in healthy subjects. The inhibit ory effect was concentration- dependent. Hypercholesterolemia induced by high- cholesterol diet enhanced ADP- induced platelet aggregation. Resveratrol 4 mg ·kg(-1)·d(-1)inhibited ADP- induced platelet aggregation in vivo de spite no changes in serum lipid levels. Conclusions Resveratrol inhibits platelet aggregation both in vitro and in vivo. This may b e one of the mechanisms by which resveratrol prevents atherosclerosis.

Effect of Xuefu Zhuyu Capsule (血府逐瘀胶囊) on Angiogenesis in Hindlimb Ischemic Rats

Objective: To investigate the effect and mechanism of Xuefu Zhuyu Capsule(血府逐瘀胶囊, XZC) on pro-angiogenesis in the hindlimb ischemic model rats. Methods: A total of 100 Sprague Dawley rats were randomly divided into a model group, a regular-dose XZC group(0.48 g·kg~(-1)·d~(-1)) and a high-dose XZC group(0.96 g·kg~(-1)·d~(-1)) using random number table method. The model of hindlimb ischemic rats were made through femoral artery embolization with Bletilla microsphere agent. XZC were given on the first day after embolization surgery and lasted 5 days. Finally 72 models were obtained with 12 in each group for each time point. The lower ischemic limb was amputated on the third day after embolization surgery. Histopathological characters and the number of blood vessels of granulation tissues were observed at 36 and 48 h after amputation, respectively. The main genes were obtained from microarray analysis and were validated using real-time quantitative polymerase chain reaction. Results: The vascular number of granulation tissues at both 36 and 48 h were characterized by new and fresh vessels. The number of angiogenesis in the high-dose XZC group at 36 and 48 h was greater compared with that in the regular-dose XZC and model groups(P0.01), and high-dose XZC at 36 h increased more vessels than that at 48 h(P0.01). Consequently, granulation tissues from the high-dose XZC group at 36 h were chosen for microarray analysis. In all, 2,085 differentially expressed genes(DEGs) were detected and 25 DEGs were determined to be directly related to angiogenesis. Four biological process terms were found including angiogenesis, regulation of angiogenesis, positive regulation of angiogenesis, and positive regulation of vascular endothelial growth factor receptor signaling pathway(P0.05). Microarray analysis also showed 49 pathways including 11 pathways related to angiogenesis. Conclusion: XZC promoted angiogenesis moderately and the mechanism involved multiple DEGs and multiple pathways.

Effect of Feitai Capsule(肺泰胶囊) on Quality of Life and Progression-Free Survival of Patients with Unresectable Non-Small Cell Lung Cancer

<正>Objective:To examine the effect of a Chinese medicinal herbal formula(Feitai Capsule,肺泰胶囊) on the quality of life(QOL) and progression-free survival(PFS) of patients with unresectable non-small cell lung cancer(NSCLC).Methods:Sixty-two patients were randomly divided into the treatment group(31 cases) and the control group(31 cases).For the treatment group,4 capsules(1.2 g/capsule) of Feitai Capsule were administered 3 times a day after meals for 3 weeks;then no drug was administered for 1 week.This schedule was continued for at least 3 more cycles(12 weeks totally).If there were no obvious toxic reactions,the treatment was extended.The patients were evaluated at least once every 8 weeks until progressive disease(PD). For the control group,the regular follow-up and evaluation were performed at least once every 8 weeks until PD.Clinical symptoms,objective response,physical constitution and energy,QOL,and PFS were evaluated regularly.Analysis of variance(ANOVA),a non-parametric test,and analysis of covariance were used to compare clinical features,amelioration of clinical symptoms,physical constitution and energy,and QOL.Kaplan-Meier analysis was used to compare the two-group PFS.Results:Sixty patients finished the final evaluation, with 30 patients in each group.Baseline characters between groups were not significantly different(P0.05). The control group had a 36.7%improvement in clinical symptoms,while the treatment group had a 73.3% improvement.This difference was statistically significant(Z=-2.632,P=0.008).The control group had a 26.7% improvement in the Karnofsky performance status(KPS),while the treatment group had a 53.4%improvement. This was also significantly different(Z=-2.182,P=0.029).A comparative analysis indicated a positive correlation (r=0.917,P0.001).Compared with the control group,QOL in the treatment group was significantly improved, except in the social/family condition and doctor-patient relationship indicators.The PFS of the treatment group and control group were 6.23 months and 4.67 months,respectively(P=0.048).Conclusion:Feitai Capsule,a Chinese medicinal herbal treatment could improve the QOL and extend the PFS of the unresectable NSCLC patients.     

Effects of Heyan Kuntai Capsule(和颜坤泰胶囊) on Follicular Development and Oocyte Cohesin Levels in Aged Mice

Objective: To evaluate the effect of Heyan Kuntai Capsule(和颜坤泰胶囊, HYKT) on the ovarian function of aged mice and expressions of cohesion complexes in oocytes. Methods: Twenty-five 9-month-old female C57BL/6J mice were randomly divided into 5 groups by block randomization method(n=5 per group), including the control group(saline), 17β-estradiol group [E_2, 100 μg/(kg·d)], and low-, medium-, and highdose of HYKT groups [0.3, 0.9, 2.7 g/(kg·d), respectively]. All mice were treated by intragastric administration for 4 weeks. Hematoxylin and eosin staining and anti-VASA staining were used to detect the amounts of follicles. The apoptosis of follicles was measured by anti-gamma H_2A histone family member X(γH_2AX) staining and Td T-mediated d UTP Nick-End Labeling(TUNEL) assay. The density of cohesin subunits, REC8 meiotic recombination protein(REC8), structural maintenance of chromosome(SMC) 1β and SMC3 in oocytes were evaluated by immunofluorescent staining. Results: After administration of E_2 and high-dose of HYKT, the total number of follicles as well as the number of primordial and primary follicles were significantly increased(P0.05). Anti-γH_2AX staining and TUNEL assay demonstrated that high-dose of HYKT and E_2 partly suppressed the apoptosis of follicles(P0.05). Furthermore, it showed an increased trend in the levels of REC8 and SMC1β, after administration with E_2 and HYKT, and no obvious change in the level of SMC3. Conclusion: HYKT could enhance the number of follicles, suppress apoptosis of oocytes and have a trend to elevate the meiotic-specific cohesin subunits(REC8 and SMC1β) in oocytes of aged mice, indicating a beneficial effect on the ovarian function in terms of the quantity and quality of follicles.     

Short-term Effect of Combined Therapy with Jinlong Capsule(金龙胶囊)and Transcatheter Arterial Chemoembolization on Patients with Primary Hepatic Carcinoma and Its Influence on Serum Osteopontin Expression

<正>Objective:To observe the clinical combination effect of Jinlong Capsule(金龙胶囊,JLC) and transcatheter arterial chemoembolization(TACE) on the patients with primary hepatic carcinoma(PHC) and JLC's influence on serum osteopontin(OPN) expression and elucidate the correlation between the serum OPN level and curative effect of JLC and TACE.Methods:A total of 98 patients with PHC were observed in a randomized controlled trial(RCT).They were assigned to the Chinese medicine(CM) group(53 patients who were treated with TACE and JLC) and the intervention group(45 patients who were treated with TACE only).The serum OPN levels were measured before and after treatment by quantitative sandwich enzyme-linked immunosorbent assay(ELISA).Forty healthy people were assigned to the control group.The clinical efficacy was observed and Karnofsky score(KPS) was graded.Results:The clinical efficacy of the CM group(60.38%) was better than that of the intervention group(40.00%),and the KPS(84.35±12.19) was higher than the intervention group(69.86±11.58)(P0.05).The serum OPN levels before and after treatment in the patients with PHC were significantly elevated compared with those in the control group(P0.01).After treatment,the OPN levels in CM group(117.69±78.50) were significantly lower compared with those in intervention group(151.09±83.90,P0.05).The OPN levels of responders were remarkably lowered than the non-responders after treatment,and the level of OPN in the CM group was lower than the intervention group(P0.05).Conclusions:The short-term clinical efficacy and the quality of life of patients with PHC can be improved by combining JLC with TACE.The serum OPN levels in PHC patients can reflect the curative effect of treatment and the prognosis of the disease.     

Effects of Corocalm (Shuguan Capsule, 疏冠胶囊) on acute myocardial ischemia in anesthetized dogs

Objective:To investigate the effects of Corocalm (Shuguan Capsule,疏冠胶囊) on acute myocardial ischemia in anesthetized dogs and its possible therapeutic mechanism.Methods:The acute ischemia model was established by ligating the left anterior descending (LAD) artery.Twenty- five dogs were randomly divided into 5 groups (5 clogs in each group):the control group (treated with normal saline 3 mL/kg),the refined Guanxin Capsule group (精制冠心胶囊,GXC 200 mg/kg),high and low dose Corocalm groups (48.5 mg/kg for low dose group and 194.0 mg/kg for high dose group) and the Diltiazem group (5 mg/kg).The animals were treated via a single duodenal administration after the model was established.The experiments used epicardial electrocardiogram (EECG) to measure the scope and degree of myocardial ischemia.Simultaneously,the coronary blood flow (CBF) and serum activity levels of creatine phosphokinase (CK) and lactate dehydrogenase (LDH) were measured by electromagnetic flow meter and automatic biochemical analyzer respectively.The plasma endothelin (ET) content was quantified by radioimmunoassay.Results:Corocalm (48.5 mg/kg and 194.0 mg/kg) significantly decreased the degree and scope of myocardial ischemia,reduced the infarct area,markedly increased the CBF,and inhibited the increase of CK and LDH activities and ET levels induced by myocardial ischemia/infarction.Conclusion:Corocalm could improve the state of acute myocardial ischemia and infarction in dogs.The mechanism of action might be correlated to increasing CBF, inhibiting CK and LDH activities and preventing ET release.
