OBJECTIVE: To study the preventive and therapeutic effect of Weitong injection(WTI) on the postoperative intestinal adhesion of rats.METHODS: Forty SD rats were randomly divided into five groups: blank control group,model control group,Dexamethasone group and high-dose WTI group and low-dose WTI group.Postoperative intestinal adhesion model was established in all the rats except those in the blank control group.On the operative day,the blank control group and the model control group received Normal saline(1 mL?kg-1);the Dexamethasone group received Dexamethasone(5 mg?kg-1),and WTI group received WTI(4 mg?kg-1 and 2 mg?kg-1,respectively) all via vena caudalis for 7 consecutive days.On day 8,laparotomy was performed on the rats for the evaluation of the degree of intestinal adhesion and the tissue of cecum was collected for the determination of the content of hydroxyproline(Hyp) and the pathological section test.RESULTS: The degree of postoperative intestinal adhesion of rats was attenuated by WTI(either high dose or low dose) or Dexamethasone.Furthermore,WTI significantly reduced the Hyp concentration in cecum tissue of rats with intestinal adhesion(P

Objective To recognize normal sinus rhythm (NSR), ventricular tachycardia (VT) and ventricular fibrillation (VF) from each other accurately and promptly. Methods A nonlinear descriptor based on multi-scale analysis, Hurst index, as a feature to quantify the nonlinear dynamics behavior of the ECG signal, was quoted in this paper. Results The nonlinear technique, Hurst index was examined and evaluated with ECG signals extracted from MIT-BIH Arrhythmia Database, MIT-BIH Malignant Ventricular Ectopy Database, and CU Ventricular Tachyarrhythmia Database under a specific moving-window length. The experiment showed good performance of this nonlinear descriptor. When the window length was 5 s long, the recognition accuracy for each of NSR, VT and VF was 100%. Besides, the computing speed was much faster than the speed obtained with a traditional non-linear technique, the complexity measure algorithm. Conclusion The Hurst index has a strong potential for life-threatening ventricular arrhythmia recognition in clinical applications.

OBJECTIVE:To reduce dispensing errors in Pharmacy intravenous admixture service(PIVAS),improve compound-ing quality of transfusion and guarantee the safety and rationality of clinic transfusion. METHODS:The case tracking method was applied to analyze each link of the work in PIVAS to find the reasons of configuration errors and control risk;and then the system tracking method was applied to analyze the hidden safety risk and the crack of quality from the inside of the system and work flow. Countermeasures and supporting continuous improvement were established to evaluate the effect of management before and after 6 months. RESULTS:Tracer methodology(TM)was adopted to find out the weakness in the key link and work flow of the cause of the configuration errors,the relative work pattern and work environment was improved,the relative system was formulated and completed,strength of rewards and punishment was increased. Through the implementation of the countermeasures,the number of dispensing errors was reduced from 81 to 38,and the error rate was reduced from 0.035% to 0.011%(P<0.01). CONCLU-SIONS:TM can be adopted in the key link and work flow of the cause of the configuration errors,aim at formulate and strictly carry out relative countermeasures to reduce errors in PIVAS,and promote the safety of drug use.

Objective To analyse subtyping of iscbemic stroke by the criteria of Trial of Org 10 172 in Acute Stroke Treatment (TOAST), its distribution, and relationship between TOAST subtypes, its risk factors and recurrence. Methods Clinical data of 441 patients of ischemic stroke were collected prospectively during October 1, 2006 to September 30, 2007. All the patients were classified by TOAST criteria into five major subtypes and followed-up for one year since its first episode. Dates of its recurrence and death due to recurrence were recorded. Results All the 441 patients with ischemic stroke could be subtyped etiologically according to TOAST criteria as follows: etiology undetermined in 42.3 percent, small-vessel occlusion in 30.9 percent, large-artery atherosclerosis in 17.3 percent, cardioembolism in 9.3 percent, and others in 0.2 percent, without statistically significant difference in its gender and age distributions. Recurrence rate of iscbemic stroke in one year since its first episode for varied subtypes was 33.3 percent for cardioembolism, 14. 6 percent for etiology undetermined, 13.7 percent for large-artery atherosclerosis and 6.9 percent for small-vessel occlusion, respectively. There was no significant difference in risk factors for varied subtypes of iscbemic stroke, including history of smoking, hypertension, diabetes, cardiac disease, and serum levels of total cholesterol, low-density lipoprotein cholesterol, fihrinogen and glucose. Conclusions Varied subtypes of iscbemic stroke had different risk factors and recurrence rate by TOAST criteria, which can be used as an etiologic classification for its secondary prevention.

Objective To study clinical effect of laparoscopy combined with gestrinone in treatment of ovarian endometriosis cyst and the prognoisi of patients. Methods A randomized, controlled, prospective study was used in this study, 78 patients with ovarian endometriosis cyst were selected in Sichuan province panzhihua city miyi people's hospital from august 2012 to august 2014, and were randomly divided into observation group and control group, 39 patients in each group. Patients in the observation group were treated with laparoscopy combined with gestrinone (2.5 mg/time, two times per week, for 6 months) intervention; patients in the control group were treated with laparoscopic intervention. After six months, the postoperative serum FSH (Follicle Stmi Ulating Hormone, FSH), Estradiol (E2) and Estradiol levels, ovarian biggest plane average diameter (D), the level of MMP-9 and TIMP -1 level, pregnancy outcome of two groups were compared and the outcome and the recurrence rate 18 months after treatment were followed up. Results Six months after treatment, the E2 and FSH levels in the observation group were better than control group, with statistically significant difference (P<0.01);the postoperative serum levels of MMP-9 and TIMP-1 in Observation group were better than control group, with statistically significant difference (P<0.01);there were 20 patients of D≤2 cm, 19 patients of D>2 cm, the postoperative ovarian shrink rate was 51.28% in the observation group; there were 5 patients of D≤2 cm, 34 patients of D>2 cm ovarian shrink ratio was 12.82% in the control group, the ovarian shrink ratio of observation group was obviously higher than control group, with statistically significant difference (P<0.01) . Follow-up for 18 months, the recurrence rate was 5.13%in the observation group, which was significantly lower than thatin the control group (25.64%), with statistically significant difference (P<0.05);the pregnancy rate was 66.66%and 30.77%in the Observation group and control group, respectively, the difference had statistical significance (P<0.01) . Conclusion Laparoscopic surgery combined with gestrinone can protect ovarian function of patients with ovarian endometriosis cyst, improve pregnancy outcomes, and reduce recurrence rate, and has good clinical value.
