Objective To evaluate the movement function of the left ventricular short-axis with parameters (velocity, acceleration and relatively force) measured with improved anatomical M-mode ultrasound. Methods Sixteen patients with myocardial ischemia coronary heart disease who had taken percutaneous transluminal coronary intervention (PCI) were enrolled. All patients were divided into two groups: group A, single major vascular stenosis (n=8);group B, more major vascular stenosis (n=8). M-mode curves of short-axis sections at mitral valve level, papillary level and apical level were recorded, then the peak myocardial velocities, acceleration and force of the systolic phase, early-diastole phase and end-diastole phase were measured at the post processing station. Results The variety ranges of average velocity and acceleration of the three levels during systolic phase were higher than that during diastole phase. The changing rate of velocity and acceleration in group B was higher than that in group A. Conclusion The new parameters that are measured and calculated with anatomical M-mode ultrasound can reflect the movement functions of coronary heart disease patients taken PCI.

Objective To analyse the difference between stage Ⅰ pure bronchioloalveolar carcinoma (BAC) and stage Ⅰ adenocarcinoma of the lung among operative cases.Methods We use the Lobectomy Cases Registration and Statistics System database (2006-2011) to compare the epidemiology,clinical presentation,image characteristics,surgical outcomes,recurrence and overall survival between BAC and adenocarcinoma groups.All the patients received lobectomy procedure in the department of thoracic surgery of Peking University People' s Hospital.Results Excluding those cases with both BAC and adenocarcinoma aspects,337 patients were enrolled.Thirty-nine patients were stage Ⅰ pure BAC and 298 patients were stage Ⅰadenocarcinoma.BAC has its proper clinical spectrum,occurring more frequently in women (69.2% vs.52.0%,P =0.042)and in younger patients (57.4 vs.61.8,P =0.014).BAC also seems to be less dependent on tobacco exposure (12.8% vs.29.9%,P =0.026).The percentage of ground-glass opacity (GGO) in CT scan of BAC patients was much more than that registered in adenocarcinoma patients (35.9% vs.9.7%,P <0.001).And the tumor size of BAC group was smaller than that of the adenocarcinoma group (1.4 cm vs.2.3 cm,P <0.001).The operation method,time,blood loss and complications were similar between the two groups.Kaplan-Meier survival curves showed that both 3-year disease-free survival (DFS) and overall survival (OS) were significantly higher in patients affected by BAC (100% vs.76.1%,P =0.030 and 100% vs.86.1%,P =0.041).Conclusion BAC presents specificity in its epidemical,clinical,radiological and evolutionary aspects.Stage Ⅰ pure BAC patients have better prognosis following video-assisted thoracoscopic lobectomy and system lymph node dissection than the similar stage adenocarcinoma patients.

Objective: To observe the impact of vareniline tartrate on vascular endothelial function and inlfammatory factor releasing in acute coronary syndrome (ACS) patients with nicotine dependence after smoking withdrawal treatment.
Methods: We recruited the in-hospital ACS patients who were smoking ≥10 cigarettes/day for more than 10 years with at least moderate nicotine dependence, and randomly divided them into 2 groups: Varenicline group, the patients received oral medication for 2 weeks and Self withdrawal group, the patients without medication assistance.n=52 in each group. All patients received (10-30) min daily mission and consulting for quit smoking for 2 weeks. The basic information was recorded and blood levels of NO, IL-6 and ET-1 were compared before and after withdrawal treatment.
Results: Compared with they were before, after 2 weeks withdrawal treatment, in Varenicline group, blood levels of ET-1 decreased as (33.950 ± 1.439) ng/L vs (170.198 ± 12.602) ng/L and IL-6 decreased as (0.103 ± 0.020) ng/L vs (0.307 ± 0.051) ng/L; in Self withdrawal group, ET-1 decreased as (60.795 ±7 .036) ng/L vs (170.511 ± 12.374) ng/L, all P<0.05; while NO levels were similar,P>0.05. After treatment, ET-1 level in Varenicline group (33.950 ± 1.439) ng/L was lower than Self withdrawal group (60.795 ± 7.036) ng/L and IL-6 level in Varenicline group (0.103 ± 0.020) ng/L was also lower than Self withdrawal group (0.258 ± 0.042) ng/L, allP<0.05; while NO levels were similar between 2 groups,P>0.05.
Conclusion: Compared with self withdrawal, varenicline tartrate may effectively inhibit inlfammatory factor releasing in ACS patients with nicotine dependence, and therefore improve the vascular endothelial function.

As one of the significant parts of medical science research in China, the research on Chinese medicine (CM) reflects the essence of healthcare tradition in the country both theoretically and clinically, and embodies the values of Chinese culture. Therefore, in the practice of ethics review on CM research protocols, besides abiding by the contemporary prevalent international principles and guidelines on bioethics, which emphasizes the scientific and bioethical value of the study, we should also stress the CM theoretical background and relevant clinical experience in the framework of Chinese culture and values. In this paper, we went over the traits of CM clinical research and the experience from the practice of ethics review by the institution review board for bioethics, and then attempted to summarize the key points for the bioethics review to CM researches in China, so as to serve as reference for the bioethics review to traditional and alternative medicine researches.

Objective To investigate the effect of expression of microRNA-27a(miR-27a) and microRNA-451(miR-451) in A2780/T cells and its relativity to multidrug resistance (MDR)1 mRNA inhibition by procyanidin. Methods Stem-loop PCR method was performed to evaluate the expression of miR-27a and miR-451 in use of procyanidin (0-40μmol/L) in 0-48 h in A2780/T cells. Additionally, over-expressing or interfecting microRNAs by using mimics or inhibitor of miR-27a and miR-451, the expression of MDR1 mRNA was assessed by RT-PCR in cells exposing to procyanidin. Results The expression of miR-27a and miR-451 was significant inhibited by procyanidin in both time- and concentration-dependency. Over-expressed MDR1 mRNA associated with miR-27a or miR-451 mimics was blocked by procyanidin, whereas there was no effect on down-expressed MDR1 mRNA associated with miR-27a or miR-451 inhibitor by procyanidin. Conclusion Procyanidin inhibits MDR1 mRNA expression by inhibiting miR-27a and miR-451 expression in A2780/T cells.

ABSTRACT:In the present study ,we aimed to identify differentially expressed proteins between induced worms (the infec‐ted mice were treated intragastrically with ED50 PZQ) and uninduced worms (control group) for clarifying the mechanism of PZQ .ED50 PZQ was used to administrate mice that were infected with S .japonicum via intragastric incubation for consecutive‐ly 30 days .Twenty‐one days later ,mice were sacrificed after treatment with 200 mg/kg PZQ for continuously five days ,and the male worms were obtained and some of them were subjected in DMEM medium with different concentrations of PZQ in vitro for 16 hours .Then the worms were washed twice and incubated in PZQ‐free medium for 72 hours .Compared with control group ,the induced worms had lesser sensitivity to PZQ .The survival rate of induced worms was 75 .6% in vitro when the con‐centration of PZQ was 112 mol/L (the concentration was 8 times of uninduced worms Lethal Concentration ) ,significantly higher than that in the uninduced worms (11 .1% ,P<0 .05) ,showing obviously tolerance .The other induced and uninduced worms were acquired and collected for 2D‐DIGE and MALDI‐TOF‐MS ,and combined with bioinformatics to analyse the func‐tion of the identified protein .Thirty differential expression proteins were confirmed between induced and uninduced worms ,in‐cluding 12 proteins up‐regulated and 18 proteins down‐regulated .These proteins respectively ascribed to cytoskeleton‐associat‐ed protein ,glucose and energy metabolism enzymes ,stress proteins ,thioredoxin peroxidase enzymes ,and other protease .Up‐or down‐regulation of these differential proteins indicated that PZQ promote or inhibit the expression of some specific genes . These findings may help to clarify the mechanism of PZQ ,simultaneously ,providing a scientific basis for exploring new vaccine candidate antigens and targets for drug therapy .
