Results The occurrence rates of agitation within postoperative 30 min in the group Ⅰ,Ⅱ and Ⅲ were 65.00%,65.00% and 15.00% respectively,the difference among three groups was statistically significant (P <0.05);the anesthesia recovery agitation score,improved Aldrete score and awakening time had statistically significant differences among 3 groups (P <0.05),the time out of the operation room had no statistical difference(P > 0.05).Conclusion Postoperative twice intravenous injection of propofol 1.00 mg/kg has obvious effect and good safety for preventing the postoperative agitation in children,which has important clinical reference value.

BACKGROUND: Continuous passive motion assisted with diathermia will promote the restoration of joint movement of the extremities.OBJECTIVE: To improve joint movement with continuous motion assisted with diathermia after surgical treatment on simple fracture of upper or lower extremity.DESIGN: A randomized controlled trial.SETTING: Huaxi Hospital of Sichuan University.PARTICIPANTS: Eighty-four cases of simple extremity fracture treated in the Orthopedic Department of Huaxi Hospital of Sichuan University from October 2000 to July 2002 were included in this trial. Of them, 16 cases were elbow movement disorder and 68 were knee movement disorder. They were randomly assigned into two groups with 42 cases each.METHODS: The 42 cases in the treatment group were preheated before continuous passive motion while those in the control group just received continuous passive motion. The improvement of joint movement between thetwo groups were assessed and compared according to the joint movement scale.MAIN OUTCOME MEASURES: The joint movement before and after treatment and the indices of joint movement scale in the two groups.RESULTS: All of the eighty-four cases entered the analysis. The joint movement in the treatment group was better than that in the control group [ (101.40 ± 25.76)° vs (86.14 ± 27.66)°, t = 5.25, P ＜ 0.01 ]. The index of joint movement scale in the treatment group was also higher than that of the control group[ (84.32 ± 16.54) vs(64. 89 ± 13.76) ] ( t = 4.24, P ＜ 0.01 ) ].CONCLUSION: Continuous passive motion assisted with diathermia is better than simple continuous passive motion in improving the joint movement and function of elbow and knee.

Objective To evaluate whether glucose is associated with thrombolysis in myocardial infarction (TIMI) flow before primary percutaneous coronary intervention (PCI).Methods Pre-operation blood glucose level, TIMI flow and baseline characteristics of 120 consecutive acute ST-segment elevation myocardial infarction (STEMI) patients treated with primary PCI were analyzed. Hyperglycemia was defined as whole blood glucose ≥7.8 mmol/L (140 mg/dL). Results Only 18 patients (15%) had TIMI 3 flow before primary PCI and hyperglycemia was observed in 87 patients (72.5%). TIMI grade 3 flow were more commonly found in the normoglycemia group compared with the hyperglycemia group before primary PCI (27.3% vs 10.3%,P

Objective To compare the particle pollution to the solution in the ampoule wrapped and broken by non-woven fabrics and medical gauze.Methods Totally 200 pcs of sterile water for injection(2 ml/pc) were randomly divided into the experimental group and the control group,with 100 pcs for each.For the experimental group,the ampoules were wrapped and broken by disinfected non-woven fabrics.For the control group,the ampoules were wrapped and broken by medical gauze.The solution was sucked from the ampoule with a 10 ml syringe and injected into a measuring cup for testing.Results The quantity of particles in the solution in the experimental group was less than that in the control group,and the difference was statistically significant (P＜0.05).Conclusion Wrapping and breaking the ampoule by disinfected non-woven fabrics can reduce particle pollution to the solution,and this method is easy to practice.

Background Constipation is a common complication after stroke, and the results investigated overseas showed the incidence was about 30% ～60%. The difference of results is so significant because the time investigated and the diagnosis criterion used are different. There are less relative report about risk factors of constipation and no report about the impact of constipation on pragnosis. The study is to investigate the incidence and risk factors of new-onset constipation after stroke in the patients with acute stroke and to evaluate the impact of new-onset constipation occurrence on the prognosis in the patients.Methods A prospective cohort study of new-onset constipation was performed to investigate 154 cases of acute stroke patients who were hospitalized from December 2003 to October 2004 in the department of neurology, the first Affiliated Hospital of Sun Yat-sen University. We recorded the demographics, medical history,stroke severity and medication used. National Institutes of Health Stroke Scale (NIHSS), Barthel Index (BI)and Modified Rankin Scale (MRS) were evaluated in the 1st week and 4th week after stroke to evaluate the neurological function and ability of an independent life. BI and MRS were recorded at the 12th week after stroke.Patients were then followed for the development of stroke, the event such as recurrence or death. Constipation was defined by Rome Ⅱ criteria.Results The incidence of new-onset constipation after stroke within 4 weeks was 55. 31%, and the highest risk was within seven days after onset of stroke. Cox regression showed that the incidence of constipation occurrence was strongly related to neurological functional status of patients in the 1st week assessed by BI and the transform of surrounding for defecation. In the 4th week and 12th week after stroke, the rates of poor prognosis in patients with constipation in middling state were both higher than patients without constipation, and the difference was statistically significant respectively(P ＜ 0. 01 ;P = 0. 012).Conclusions The new-onset constipation occurrence in acute stroke is very common and its main risk factor is functional status assessed by Barthel Index at the 1st week after onset and the transform of surrounding for defecation. The results indicate that the new-onset constipation occurrence after stroke has negative effects on the outcome of partial stroke patients.

Objective To explore effect of rehabilitation training on deglutition disorders of children with cerebral palsy . Methods Twenty-seven children patients from January to June in 2013 were set as control group and thirty-one patients from July 2013 to January 2014 as experiment group. The children in the control group were treated with tube-feeding combined with spoon feeding and bottle-feeding by professional nurse. Children in the experiment group were treated with oral rehabilitation training by professional therapists and nurses apart from the same feeding as in the control group. The two groups were compared in terms of effect of deglutition within 4 weeks, time and rate of removing the stomach tube. Results The recovery of deglutition function in the experiment group was much better than that in the control group , the total effective rate and rate of removing the stomach tube within 3 months were higher and the intubation duration was significantly lower as compared with those of the control group (P < 0.01). Conclusion Rehabilitation training can improve the recovery of deglutition disorders, improve active feeding ability of children with cerebral palsy, shorten time of tube feeding and improve their life quality.

Objective To realize basic status of occupational exposure among medical postgraduates,and provide theoretical evidence for making occupational precaution measures.Methods Data about occupational exposure among medical postgraduates in a teaching hospital between January 2011 and December 2013 were analyzed retro-spectively.Results A total of 3 362 medical postgraduates were monitored,56 (1 .67%)sustained occupational ex-posure.The most common occupational exposure sites were left hand thumbs(n=15,26.79%),occupational expo-sure most frequently occurred during operation(n=29,51 .79%),a total of 40(71 .43%)occupational exposure oc-curred during the process of operation and invasive procedure,all were sharp injuries.46(82.14%)exposure sources were with bloodborne-transmitted diseases.Surgery students accounted for 66.07%(n =37)of students sustained occupational exposure,exposure rate in master’s candidates was higher than doctoral candidates(2.31 % vs 0.28%,χ2 =18.325,P <0.001 ).After timely treatment and preventive medication,none of the students were infected. Conclusion It is necessary to strengthen the occupational safety education for medical postgraduates,improve pre-caution awareness,standardize all kinds of procedures,and implement standard precaution;timely and effective treatment after exposure is important for reducing occupational injury among medical postgraduates.

This study examined the relationship between PDGF-induced proliferation of vascular smooth muscle cells (VSMCs) and Nur77 expression and the effect of atorvastatin on VSMC proliferation and Nur77 in PDGF-treated VSMCs. Rat VSMCs were isolated and cultured. After incubation with atorvastatin or Nur77 siRNA, the cells were stimulated with PDGF and detected for BrdU incorporation to measure the proliferation of the VSMCs. Quantitative PCR and Western blotting were used to determine the Nur77 protein and the CREB phosphorylation level, to observe their relations with PDGF-induced VSMC proliferation. Our results showed that PDGF increased the BrdU incorporation in VSMCs, suggesting that it induced the proliferation of the cells. The VSMC proliferation was associated with increased Nur77 expression and elevated CREB phosphorylation. Atorvastatin inhibited the PDGF-induced VSMC proliferation, suppressed Nur77 expression. After silencing of Nur77 gene, the PDGF-induced VSMC proliferation was decreased. It was concluded that PDGF-induced VSMC proliferation was related to the Nur77 expression and CREB phosphorylation. Atorvastatin reduced the Nur77 expression and, at the same time, inhibited the VSMC proliferation.
