Objective To investigate the operation effect of cardiopulmonary suppository before painless artificial abortion. Methods 300 patients with painless artificial abortion were enrolled in our hospital from August 2013 to October 2016. They were divided into control group and observation group according to randomized and double-blind way. The patients in the control group were not given any drugs before operation.The patients in the observation group were placed preoperatively in the posterior vagina. The cervical relaxation, expansion time, intraoperative blood loss, analgesic effect and induced abortion syndrome Happening were observed in the two groups. Results The cervical relaxation rate in the observation group was 132/150 (88.00%),which was significantly better than that of the control group 83/150 (55.33%), the difference was statistically significant (P<0.05). The effective rate of analgesia in the observation group was 94.67%, significantly higher than that in the control group 70% . In the observation group, the time of dilatation was (31.6±3.59) s, intraoperative blood loss was (8.9±3.12) mL, and the incidence of induced abortion syndrome was 2.67%, which were significantly better than those in the control group, the time of dilatation (53.2±4.21) s, intraoperative blood loss (14.9±3.96) mL, abortion syndrome occurred 25.33% , the difference was statistically significant (P<0.05). Conclusion The painless artificial abortion before the use of preoperative suppository, can effectively expand the patient's cervix, reduce the operation time, and effectively reduce the amount of intraoperative blood loss, painless abortion is an effective relief of patient suffering drug.

Objective To investigate the effects of prone positioning on oxygenation and lung mechanics in neonates with mechanical ventilation.Methods Twenty cases of neonates,selected from Shanghai Children′s Hospital(from May 2008 to Feb 2009),were randomized to supine-prone position group (n=10) and prone-supine position group (n=10) using a crossover design.During 6h,these neonates were placed in the supine position for 3h then in the prone position for 3h or in reversed order.The ventilator parameters,results of arterial blood gas and the lung mechanics were recorded.Results Without obvious changes of ventilator parameters,PaO2 improved significantly when the incubated neonates were placed in the prone position for 3h compared to supine [(74.50±15.37)mm Hg vs (67.60±13.66)mm Hg,1mm Hg=0.133kPa,P<0.05).Similarly,oxygenation index of prone positioning for 3h was (201.86±55.96)mm Hg,which was higher than that of (184.38±63.58)mm Hg,the value of supine positioning for 3 h.There were significant differences (P<0.05).Our results showed that 60% (12/20) of the neonates responded to prone positioning,with oxysenation index increasing as much as 17mm Hg on average.Improvement in minute volume,tidal volume and dynamic compliance of the lung were achieved after prone positioning for 3h (P=0.011,0.020,0.045).The airway resistance did not decrease significantly (P=0.422),but the average decreased in the prone position.Conclusion Oxygenation and the lung mechanics are improved significantly in the neonates with prone position compared with supine position.

Capacity assessment is of significant priority for medical treatment and clinical research invol-ving mental disorder patients,as to protect an individual's fundamental rights.Clinical judgment of individual's ca-pacity to consent most focus on medical situation,well-designed capacity assessment instruments should be used to support experienced clinical judgment.Capacity to consent can be adequately captured by measuring the constructs of understanding,appreciation,reasoning and communicating /expressing a choice.A large number of instruments designed by foreign developers to assess capacity to consent need validation and implementation in China,the in-strument designed by Chinese researchers has not been widely agreed.Establishing an effective capacity assessment instrument with psychometric properties (validity and reliability),which considering the clinical practice and culture background in china would be a breakthrough in methodology.

Objective To exPlore the theraPeutic effect of cycloVirobuxine_D ( CVB_D) on heart failure by obserVing the influences of CVB_D on cardiac function,myocardial morPhology and structure in rats with heart failure. Methods The rat model of heart failure was established by ligating left anterior descending coronary artery,and then the rats were randomly diVided into 5 grouPs,Plus the sham grouP. EchocardiograPhy was used to assess cardiac function,including EF,LVSF,SV,HR,CO and so on. Myocardial tissue section was obtained. Change in the myocardial tissue was obserVed by HE staining. Myocardial ultra_structure was obserVed by using transmission electron microscoPe. Results As comPared with the model grouP,EF and LVSF were significantly increased in medium and high dose CVB_D grouPs (P<0. 05 or P<0. 01),SV was increased in low and medium dose CVB_D grouPs (P<0. 05),CO was increased in low,medium and high dose CVB_D grouPs (P<0. 05),LVIDs was decreased and LVPWs was increased in high dose CVB_D grouP (P<0. 05). Under light microscoPe,changes of myocardial structures were obserVed in different CVB_D dose grouPs: myocardial fiber gradually became tidy, striPes became clear, and contour became clear. The changes of myocardial ultra_structure were obserVed under transmission electron microscoPe: the myocardial fiber breakage was reduced and the number of mitochondria was increased,swelling degeneration was alleViated.

BACKGROUND:The mechanical environment of skin tissue and spreading state of epithelial cels are closely related with the wound healing and scar formation process. OBJECTIVE:To analyze the effect of extracelular mechanical stimulation on cel spreading, to test the cel proliferation in order to analyze the effect of spreading form on cel proliferation and other physiological activities. METHODS: Cyclic sine wave mechanical stretching was exerted on immortalized human keratinocyte by using FX-4000 flexible substrate loading system, on the condition of 0.2 Hz and at frequency of 10% amplitudes. The spreading form was compared at 0, 24 and 48 hours, the cel proliferation was analyzed with flow cytometry, and the distribution of vinculin was analyzed with immunofluorescence staining. RESULTS AND CONCLUSION: human keratinocyte would keep the spreading state and could induce more cel proliferation by 24 hours mechanical stretching stimulation. Conversely, after stimulated for 48 hours, the morphology of the human keratinocyte was significantly changed, and the number of human keratinocyte in the division stage was larger than that in the static control group; under tensile stress, the distribution of vinculin was transformed from the surrounding nucleus membrane area to the cel edge. The results indicate that proper mechanical stimulate can increase cel proliferation with keeping cel spreading and adhesion state; the stimulating time of continuous cyclic stretching is the major factor to determine cel spreading morphology and adhesion regions of immortalized human keratinocyte.
