1.Research on Prevention and Treatment of Cardiovascular Disease by Translational Medicine Based Chinese Medicine.
Chinese Journal of Integrated Traditional and Western Medicine 2015;35(5):623-626
Translational medicine is inevitable in the development of modern medicine, and the uprising concept of translational medicine provides an opportunity for the development of Chinese medicine (CM). Their ideas are well communicated. There are two patterns of researching on CM based on translational medicine: 'literature to bench to bedside' and 'bench to bedside to bench'. CM has her advantages in preventing and treating cardiovascular disease. Effective methods for preventing and treating cardiovascular disease by CM should be further studied based on translational medicine concepts.

Objective To evaluate the efficacy of decortication by video-assisted thoracic surgery (VATS) in pa﹣tients with tuberculous empyema, and discuss its indications. Methods 60 patients with tuberculous empyema who underwent decortication by VATS for surgical management from December 2010 to December 2015 were included. Under a thoracoscope, we cleaned up the pus, separated adhesions, scraped granulation tissues and caseous necrosis on the inner wall of the abscess cavity, and stripped the thickened fiberboard of the parietal and visceral pleurae. Af﹣ter the procedure, sufficient drainage and antituberculosis therapy were carried out. Results All the patients in this group were operated successfully. All the patients were cured without perioperative death and complications. No re﹣currence of empyema was observed at the follow-up examination from 2 months to 5 years, and suffered pulmonary reexpansions were better. Conclusions The decortication by VATS for tuberculous empyema is safe, effective, mini﹣mally invasive. The imaging manifestations of pleural thickening in 1 cm, no obvious calcification, no serious lesions in the lungs are the indications for the operation.

AIM: Recent studies showed that stem cells could replace injured cardiomyocyte and increase the number of functional cardiomyocytes. Researching the pertinent literature in China Journal Full-text Database (CJFD) published between 2005 and 2008 indicated that the researches on stem cell transplantation in the treatment of primary dilated cardiomyopathy were few. This study investigated the therapeutic efficacy and security of peripheral blood stem cell transplantation in coronary artery in treatment of dilated cardiomyopathy and its effects on left ventricular function. METHODS: Forty-two patients with dilated cardiomyopathy between December 2006 and September 2007 were enrolled at the Department of Cardiology of First People's Hospital of Yunnan, including twenty-eight males and fourteen females, averagely aged (56?3) years. Inclusive criteria: patients with less than 65 years, left ventricular enlargement, and left ventricular ejection fraction (LVEF) ≤ 45%, and without coronary artery disease after coronary arteriongraphy. Informed consents were obtained from patients. Patients were divided into stem cell transplantation group (n=15) and control group (n=27) on the basis of whether being treated by stem cell transplantation. Patients in the stem cell transplantation group were consecutively administered granulocyte colony-stimulating factor (G-CSF) by hypodermic injection to stimulate bone marrow stem cells themselves based on conventional treatment for five days. Peripheral blood stem cell suspension was disassociated on the 6th day, and the collected suspension was injected into left anterior descending branch over the wire saccule tube for autologous peripheral blood stem cell transplantation. Patients in the control group were administered by conventional treatment of dilated cardiomyopathy. Security and adverse reaction were observed during the mobilization, collection and returning injection of peripheral blood stem cell by coronary artery. Morphous, cardiac function and motion index of left ventricle wall were evaluated using ultrasoundcardiogram before and 3 months after transplantation. Survival rate and incidence rate of heart incidents were compared. RESULTS: Three months after stem cell transplantation in coronary artery, there were a significant decrease in cardiac end-systolic volume (ESV), cardiac end-diastolic volume (EDV) and motion index of left ventricle wall, but a significant increase in LVEF(P

Drought stress exerts a considerable effect on growth, physiology and secondary metabolisms of the medicinal plants. It could inhabit the growth of the medicinal plants but promote secretion of secondary metabolites. Other researches indicated that the medicinal plants could depend on the ABA signaling pathway and secreting osmotic substances to resist the drought stress and reduce the damage by it. The article concludes the changes in growth, physiology, secondary metabolisms and response mechanisms of medicinal plants to drought stress that provides a theoretical basis for exploring the relationship between medicinal plants and drought stress.

Restriction site amplification polymorphism (RSAP) markers were employed to access the genetic diversity and relationship of 120 lilyturf germplasms from different geographical origins. Sixteen RSAP primer pairs generated 326 polymorphic bands, of which 318 (97.55%) were polymorphic. The value of polymorphism information content (PIC) ranged from 0.87 to 0.95 with an average of 0.92. These results indicated there was abundant genetic diversity among samples. The results of data analysis on 20 population showed that the value of percentage of polymorphic locus (PPL), Nei's gene diversity (H) and Shannon's information index (I) were 19.94%-85.58%, 0.082 6-0.210 7, 0.120 6-0.328 1 respectively. The most abundant genetic diversity was found in the O. japonicus population from Zhejiang and the least in the Liriope minor population. The genetic distance among 20 population was 0.024 6-0.286 8, of which the minimum genetic distance was 0.024 6 between population I and population 13 while the maximum 0.286 8 between population 5 and population 15. Coefficient of genetic differentiation among natural populations was 0.115 3 (Gst). And the gene differentiation contributed to 43.07% of the total genetic variation among populations and to 56.93% within populations. The total gene flow (Nm) was 0.660 9. UPMGA clustering analysis was basically similar to of the principle coordinate analysis (PCA). The 120 samples were classified into four major groups, which were basically corresponded with the genetic relationships based on morphological traits. The results of UPMGA and PCA were also consistent with geographical origins.

Aim To investigate whether rosuvastatin induced reduction of atherosclerotic plaque was related to the expression of Sialyltransferase ( ST6 Gal-Ⅰ) in ApoE-/ - mice. Methods Six-weeks old ApoE-/ -mice fed with high fat were divided randomly into three groups: baseline group ( n=12 ) , control group ( n=12 ) and rosuvastatin group ( n =12 ) . Sixteen weeks later, control group was sacrificed. Serum and aortic intima were saved. Control group and rosuvastatin group were fed for seven weeks continually. Concentra-tions of serum lipids(TC, TG, LDL and HDL) were analyzed. Sections from the aortic root were examined by Hematoxylin-Eosin( HE) staining. The size of ath-erosclerotic lesion in each section was evaluated. Ex-pression of ST6 Gal-Ⅰ in aortic intima was detected by immunohistochemistry. Results Plasma TG and LDL-C, plaque areas and intimal thickness of control group were significant higher than those of baseline group ( P<0. 05 ) . Those results indicated that the AS model was successfully constructed. After seven weeks, the plaque areas and concentrations of serum lipids of rosu-vastatin group were obviously smaller than those of con-trol group(P<0. 05). The expression of ST6Gal-Ⅰin aortic root was decreased in control group compared to the baseline, and which was increased in control group compared to the rosuvastatin group. Conclusion Ro-suvastatin could inhibit the progression of atherosclero-sis, which might be related to the expression of ST6Gal-Ⅰ in aortic root.
