ABSTRACT

OBJECTIVE To study the effects of Shenfu yixin granule on mitochondrial autophagy of cardiomyocytes in rats with heart failure after acute myocardial infarction. METHODS The model of heart failure after acute myocardial infarction was established by ligaturing the anterior descending branch of the left coronary artery in rats. The model rats were divided into model group,Shenfu yixin granule low-dose and high-dose groups (1.76,8.8 g/kg),Fosinopril sodium tablets group (positive control ,4 mg/kg),sham operation group was set up (only threading without ligation at the same position ),with 8 rats in each group. After 4 weeks of drug intervention ,the hemodynamic indexes of rats in each group were measured by physiological recorder. The pathological changes of myocardial tissue were observed in each group. The level of oxidative stress in cardiomyocytes , mitochondrial membrane potential ,protein expression of PTEN-induced putative kinase 1(PINK1),E3 ubiquitin ligase Parkin and ubiquitin binding protein P 62 in myocardial tissue of rats in each group were detected. RESULTS Compared with sham operation group ,the pathological injuries such as myocardial fiber morphology disorder and inflammatory cell infiltration were serious. The left ventricular end systolic pressure (LVESP),maximum rate of rise of left ventricular internal pressure (+dp/dtmax), maximun rate of decrease of left ventricular internal pressure (-dp/dtmax),total antioxidant capacity ,mitochondrial membrane potential,PINK1,Parkin and P 62 protein expression were significantly decreased in model group (P<0.01). The left ventricular end diastolic pressure (LVEDP),the level of reactive oxygen species and the activity of reduced nicotinamide adenine dinucleotide phosphate in left ventricular ischemic cardiomyocytes were significantly increased (P<0.01). Compared with model group ,the pathological injuries of myocardial tissue in intervention groups were alleviated ,and above indexes were improved in varying degrees(P<0.01 or P<0.05). CONCLUSIONS Shenfu y ixin granule can reduce the level of oxidative stress and alleviate heart failure after acute myocardial infarction ,which may be related to the activation of Parkin-dependent pathway to strengthen mitochondrial autophagy and reduce mitochondrial dysfunction.

ABSTRACT

Objective To explore the nursing method for the prevention and treatment of vaginal adhesions in patients treated with full-dose radiotherapy for cervical cancer. Methods From 2015 to 2016, 80 cervical cancer patients who received radiotherapy were treated with domestic vaginal washing, vaginal local use of"Fufangbao", infection control, diet and sexual rehabilitation guidance, and so on, and the nursing outcome was evaluated. Results Of the 80 patients, 6 were lost during follow-up, resulting in a follow-up rate of 925%. Ten, five, and three patients were found to have grade 1, 2, and 3 vaginal toxicity, respectively. The patients with grade 1 vaginal toxicity were not treated with special treatment and were asked to do more vaginal washing. The patients with grade 2 and 3 vaginal toxicity were treated with daily vaginal washing and"Fufangbao" for repairing the vagina;vaginal adhesions disappeared or improved 3 months later. The patients with no vaginal adhesions had regular sexual intercourse and thus had improved quality of life. Conclusions Effective clinical nursing can reduce the incidence of vaginal adhesions and stenosis, improve patients' quality of life, and promote the harmony of family.

ABSTRACT

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.

ABSTRACT

Objective: To compare the percutaneous transluminal septal myocardial ablation (PTSMA) and percutaneous transluminal septal tunnel myocardial ablation (PTSTMA) on cardiac function in experimental canines. Methods: According to CAG determined coronary septal branches, a total of 25 hybrized canines were divided into 2 groups:PTSMA group, n=13 canines with the bigger septal branches and PTSTMA group, n=12 canines with the smaller or uneven septal branches. Alcohol ablation model was established. Electrocardiograph (ECG) at before and after the operation, biomarkers for myocardial injury, echocardiography and hemodynamic changes were recorded. The animals were scariifes at 1 week after operation, the pathological changes in ventricular septal were observed by HE and Masson staining. Results: Myocardial infarction (MI) could be induced by either PTSMA or PTSTMA and the thickness of septal was decreased. LVEDd, LVEF and hemodynamic indexes were similar between 2 groups. The alcohol volume used in operation, EKG and echocardiography ifndings were similar between 2 groups, P>0.05. Pathological staining indicated that there was a well-demarcate between the ablation focal and normal myocardium, merging area had neutrophiles invasion, infarcted cells were partially having the ghost cell sample and they were gradually replaced by ifbrous tissue. There was nest-like necrosis in ablated lumen and the normal vessel wall disappeared. PTSMA group had vessel lumen conifguration in septal branch and the necrosis limited inside the lumen;while in PTSTMA group, the vessel wall of was discontinued and some necrosis materials move out to from lumen. Conclusion: Both PTSMA and PTSTMA were effective for alcohol septal ablation in different coronary septal branches, the impacts on cardiac function and hemodynamic changes were similar in experimental canines.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

With the increasing incidence and mortality of coronary heart disease (CHD) in China, the prevention and treatment of CHD is no time to delay. Since Professor Gruentzig completed the first human case of percutaneous transluminal coronary angioplasty (PTCA) in 1977, percutaneous coronary intervention (PCI) had reached to a new page. After three decades of development and change, PCI has been improved and matured gradually from the early PTCA to the current stent era. With the advent of stents, the rate of restenosis after PCI was significantly reduced from 30%-50% to 10%-20%. But stent restenosis was still with no total cure. The issue of how to prevent the stent restenosis has become a long-term major issue for the exploration in both clinical and preclinical medicine. Therefore, this paper reviewed the etiology, pathology, related risk factors, latest diagnosis methods, prevention and treatment of stent restenosis by integrative medicine.

ABSTRACT

Objective To investigate the mechanism and prevention of syncope on patients with hypertrophic cardiomyopathy (HCM). Methods Seventy-six cases of HOCM (obstruction group) were successfully operated by PTSMA and oral ACEI/ARB. After six months , they were treated with β-receptor blocker. Another 29 patients (control group) with LVOTPG < 50 mmHg or < 70 mmHg after pharmacologic stress test (PST), have being treated with β-receptor blocker. The results was observed as follow: (1) the difference of between syncope incidence and positive incidence induced by PST in control group; (2) the difference of syncope incidence at half year, a year and admission in control group; (3) the difference of syncope incidence in obstruction group before and after operation; (4) the difference of syncope incidence after six months between two groups at same period; (5) the difference of syncope incidence one year between two groups. Results In control group, the syncope positive incidence induced PST was 55.5%. Treating with medications for half a year , syncope incidence significantly dropped than that on admission (P < 0.05); Obstruction group syncope incidence in the history obviously lower than the control group syncope positive induced PST (P < 0.05), and half a year after takingβ-receptor blocker syncope incidence was significantly dropped than before (P < 0.01). Conclusions The mechanism of syncope with HOCM is not only obstruction but also neuronal reflex. PST is an very useful inspection item for screening the ablation indication, analysis syncope mechanism, and guiding clinical medication.β-receptor blocker is an effective drug on treating and preventing syncope with HCM.
