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 study the prenatal genetic diagnostic methods for hemophilia A fetus.Methods From 2002 to 2006,19 hemophilia A families were diagnosed either by long distance-polymerase chain reaction(LD-PCR)for factor Ⅷ intron 22 inversion or by the DNA polymorphism genetic linkage analysis of factorⅧin the Beijing Chaoyang Hospital.Results (1)Totally 19 women,with 22pregnancies received the prenatal diagnosis of fetal hemophilia A.The average week at diagnosis was 23(17-34)weeks.All the direct fetal blood sampling(DFBS)were successful.There was no fetal-loss caused by the procedures.(2)Of the 19 hemophilia A families,14 appeared to be factorⅧintron 22inversion,in which 16 prenatal diagnoses were done,10 fetuses were diagnosed as genetical hemophilia A patients,and 6 fetuses were normal.(3)Using combined polymorphism genetic linkage analysis 6 prenatal diagnoses were done,including one woman's two pregnancies,in which both her fetuses were diagnosed as genetical hemophilia A patients.(4)Factor Ⅷ levels of 16 fetuses were measured,and 6 fetuses were unmeasured either because the pregnancy weeks were lower than 20 weeks or the parents refused.Factor Ⅷlevel ranged from 0 to 198%.There were 11 fetuses whose factor Ⅷ levels were lower than 10%.Ten of them were diagnosed to be genetical hemophilia A patients,and in only one boy the factorⅧlevel was 2%,but the genetic diagnosis was normal and for one year's follow up he was doing normal.Conclusion LDPCR combined with polymorphism genetic linkage analysis enables a quick and correct detection ofhemophilia A carrier.For a carrier pregnancy.prenatal diagnosis could be done for the male fetus.Factor Ⅷ deficiency of the fetus could help make the diagnosis but the final diagnosis should be based on genetic evidence.

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.

OBJECTIVETo explore the neuroprotective effect and mechanism of picroside II on extracellular regulated protein kinases1/2 (ERK1/2) signal transduction pathway in cerebral ischemia injuryrats. METHODS The middle cerebral artery occlusion (MCAO) model was established by inserting a monofilament into middle cerebral artery. Totally 96 successfully modeled Wistar rats were divided into the modelgroup, the treatment (picroside II) group, the Lipopolysachcaride (LPS) group, and the U0126 group according to random digit table. Each group was further divided into 3 subgroups, i.e. 6, 12, and 24 h sub-groups. Picroside II (20 mg/kg) was peritoneally injected to rats in the treatment group 2 h after ischemia.LPS (20 mg/kg) and Picroside II (20 mg/kg) were peritoneally injected to rats in the LPS group 2 h after ischemia. U0126-EtOH (20 mg/kg)and Picroside II (20 mg/kg) were peritoneally injected to rats in the U0126group 2 h after ischemia. Equal volume of normal saline was peritoneally injected to rats in the control groupand the model group. The neurobehavioral function was evaluated by modified neurological severity score(mNSS) test. The structure of neurons was observed using hematoxylin-eosinstaining (HE) staining. Theapoptotic cells were detected using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The expression of phosphorylated extracellular signal-regulated protein kinase1,2 (pERK1,2) in cortex was detected using immunohistochemistry (IHC) and Western blot.

RESULTSAfter cerebral ischemia injury neurological impairment score increased, the damage of neuron in the cortical area was aggravated, apoptotic cells increased in the model group as time went by. The expression of pERK1/2 increased more significantly in the model group than in the control group (P <0.05). The damage of neuron in the cortical area was milder, while apoptotic cells decreased, the expression of pERK1f2 obviously decreased more in the treatment group and the U0126 group (P < 0.05). The early damage of neuron in the cortical area was more severe, apoptotic cells and the expression of pERK12 were comparatively higher in early stage of the LPS group, but the expression of pERK1/2 was somewhat decreased in late stage.

CONCLUSIONSActivating ERK12 pathway could mediate apoptosis and inflammatory reactions of neurons after cerebral ischemia injury. Picroside II could protect the nerve system possibly through reducing activation of ERKI2 pathway, inhibiting apoptosis of neurons and inflammation reaction.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.
