This study was aimed to observe the safety and effectiveness ofShugan Jieyu Capsules in the treatment of vasovagal syncope (VVS) with mild-to-moderate depression and anxiety, and to compare the effect with Flupentixol and Melitracen Tablets. A total of 89 VVS cases with mild-to-moderate depression and anxiety were randomly divided into 3 groups, which were group A (Shugan Jieyu Capsules group), group B (Flupentixol and Melitracen Tablets) and group C (control group). Based on the conventional therapy of VVS treatment, treatments were given to all three groups for 8 weeks. And the negative conversion ratio of VVS in each group was observed. Hamilton Depression Scale (HAMD 24 items) and Hamilton Anxiety Scale (HAMA) were evaluated for the calculation of reductive rate. Treatment emergent symptoms scale (TESS) was used in the evaluation of adverse reactions of both medications during the treatment. In the 12-month follow-up after treatment, the recurrence rate of syncope was observed in each group. The results showed that compared with pretreatment, HAMD-24 and HAMA scores of group A and group B after treatment were significantly reduced (P < 0.05). Compared with group C, the heat-up tilt testing-negative rate, HAMD-24 and HAMA reductive rate of group A and group B after treatment were significantly increased (P < 0.05). Compared with group B, the negative rate, HAMD-24 and HAMA reductive rate of group A were more significant (P < 0.05). After treatment, scores for TESS of group A was significantly lower than group B (P< 0.05). In the 24-month follow-up, the recurrence rate of syncope of group A and group B was significantly lower than group C (P < 0.05); and group A was obviously better than group B (P < 0.05). It was concluded thatShugan Jieyu Capsules can be used in the treatment of VVS with mild-to-moderate depression and anxiety. Its effectiveness and safety may be better than Flupentixol and Melitracen Tablets.

This study was aimed to investigate the effect ofDanlou pills on prevent atherosclerosis from hypercholesterolemia rabbit and its relationship with inflammatory factors as well as PI3K/AKT signal pathways. A total of 24 Japanese male white rabbits were randomly divided into the control group (CL), model group (M) and Danlou group (DL), with 8 in each group. Normal diet was given to CL rabbits. High-fat diet was given to rabbits in other groups to establish the atherosclerosis model. Danlou pills (0.5 g·kg-1·d-1) were also given to DL rabbits. Rabbits were sacrificed after 9-week medication. The contents of blood lipid, TNF-α and IL-6 were detected. HE staining was used in the observation of histological changes in the aorta. Western blot was used to observe PI3K and p-AKT expression in the aorta. The results showed that compared with CL, the contents of TG, TC, LDL, IL-6 and TNF-α were significantly increased in M (P < 0.01); PI3K and p-AKT expression in the aorta were significantly decreased (P < 0.01). Compared with M, blood lipid, IL-6 and TNF-α were significantly reduced in DL (P < 0.05, orP < 0.01); PI3K and p-AKT expression were significantly increased (P < 0.01). It was concluded thatDanlou pills had prevention effects on atherosclerosis through reducing blood lipid and inflammatory factors. The action mechanism maybe related to the activation of PI3K/AKT signal pathways.

Objective To investigate the characteristics of coronary vessel re-endothelialization after placement of drug-eluting stents (DES), and to provide clinical evidence for the double anti-platelet treatment. Methods Optical coherence tomography (OCT) was performed in 43 patients in 1 year after DES implantation. Characteristics of re-endothelialization and percentage of neointimal coverage of stent struts were evaluated by OCT. Results The rate of stent struts intimal coverage was 90.70%, and the remain was lack of endothelial coverage; The ratio of neointimal thickness (NIT) between 0-99, 100-199 and above 200 microns was 19.92%, 37.55% and 42.53%, respectively. The rate of neointimal coverage was higher and the degree of neointimal hy-perplasia was more extensive in patients with DM and in patients with ACS than those of patients without DM and of patients with stable angina pectoris. Conclusion One year after stent placement, most of the stent struts were covered with neointima and few struts obtained poor coverage of endothelial. DM and ACS may be impact factors for the progress of re-endothelialization after DES placement.

Objective To explore the method and efficiency of percutaneous transluminal septal tunnet myocardial ablation(PTSTMA) in treatment of 26 cases hypertrophic obstructive cardiomyopathy (HOCM) who were not suitable for conventional technology.Methods Firstly,we used a monorail Balloon which was slightly bigger than the interventricular septal branch of coronary artery and dilated it until posterior septal.After that,an OTW Balloon with larger size than the monorail was used to dilate again until made aventricular septum tunnel.Then,some alcohol was injected and PTSTMA was performed.Finally,we did the other and/or another interventricular septal branch by above method until the left ventricular outflow tract pressure gradient (LVOTPG) reduced ≥50％.The clinical indexes of the 26 cases HOCM immediately pest-operation of PTSTMA were observed and the follow up data during short term and metaphase were analyzed.Results The LVOTPG reduced ≥50％ in the26 cases HOCM,immediately after PTSTMA,the LVOTPG reduced from (75.6 ±22.4)mm Hg to (21.4 ± 5.8) mm Hg (t =11.94,P ＜ 0.01).At three months after ablation,the thickness of septal myocardium reduced from (22.8 ± 5.8) ram before ablation to (16.8 ± 4.2) mm(t =4.27,P ＜ 0.01),left atrium dimension reduced from(48.0 ±7.0) mm to (42.0 ±8.6) mm (t =2.76,P ＜0.01).Followed up 6.0to 60.0 months,the patients suffering from chest pain reduced from 14 cases before to 4 cases after the procedure(53.8％ (14/26) vs 15.4％ (4/26),x2 =8.49,P ＜ 0.01),the patients with expiratory dyspnea reduced from 26 cases to 5 cases(100％ (26/26) vs 19.2％ (5/26),x2 =35.22,P ＜ 0.01),NYHA functional class improved from (2.4 ± 0.6) to (1.4 ± 0.7) (t =5.53,P ＜ 0.01).Conclusion The PTSTMA was a supplemental method of PTSMA on treating HOCM,which was safe and useful during the short term and metaphase.

Objective To observe the short-term quality of life in patients with obstructive hypertrophic cardiomyopathy (OHCM) after percutaneous transluminal septal tunnel myocardial ablation (PTSTMA). Methods The quality of life in patients with OHCM were assessed by the SF-36 before and three months after PTSTMA. Results Three months after the procedure , quality of life was markedly improved at different variances in patients with OHCM as compared with the baseline. The linear regression analysis showed the factors influencing quality of life were character, coexistence with other diseases, and 6-minute walk test. Conclusions Percutaneous transluminal septal tunnel myocardial ablation can improve the short-term quality of life in patients with OHCM. Postoperative psychological counseling and rehabilitation guidance can practically enhance quality of life.

Objective To investigate the relationship between body mass index (BMI) and coronary artery calcification in order to provide theoretical and clinical basis for the prevention and treatment of coronary artery calcification.Methods Ninety hundred and eighty-three cases were selected as our subjects who were hospitalized in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from Jan.2010 to Jul.2010 and undergone dual source CT coronary angiography.Of them,419 cases were male(male group),and 564 female (female group).The general information,clinical and biochemical indexes and coronary CTA results were collected.The patients were divided according to the BML Multivariate logistic regression analysis was applied to analyzed the relationship between BMI and coronary artery calcification,and multiple linear regression analysis was applied to analyzed the relationship between coronary artery calcification and BMI.Results There were significant differences between male group and female group in terms of age,height,body mass,BMI,smoking history,glomerular filtration rate (eGFR),triglyceride (TG),high density lipoprotein (HDL-C),left ventricular ejection fraction (LVEF),serum calcium,with peripheral vascular disease,as well as the baseline drugs,angiotensin converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB),calcium antagonists (CCB),statins compared the differences were statistically significant (P ＜ 0.05).The rate of slight coronary artery calcification in male group and female groups were not statistically significant(x2 =0.714,P =0.398),while the rate of no calcification,severe calcification were statistically significant (P ＜ 0.05).Multivariate Logistic regression analysis showed that high BMI(regression coefficient was-1.670,OR =0.967,95％ CI =0.953 ～ 0.980,P =0.005),age (regression coefficient was 1.422,OR =4.416,95％ CI:1.015 ～ 16.927,P =0.001),history of hypertension (regression coefficient was 0.128,OR =1.521,95％ CI:1.262 ～ 1.830,P =0.002),history of diabetes mellitus (regression coefficient was 0.364,OR =1.439,95 ％ CI:1.098 ～ 1.885,P =0.008),eGFR (regression coefficient was-0.5420,OR =0.004,95％ CI:0.001-0.019,P =0.014),LVEF (regression coefficient was-1.153,OR =0.316,95％ CI:0.127-0.787,P =0.002) and statins(regression coefficient was-6.745,OR:0.323,95％ CI:0.138-0.754,P =0.032) were correlated with coronary artery calcification.Multiple stepwise linear regression analysis showed that only eGFR(r =0.79,95％ CI:0.69-0.92,P =0.001) was in the equation.Conclusion High BMI is a protective factor for severe coronary artery calcification,but there is on linear correlation between BMI and moderate to severe coronary artery calcification score in patients.
