Objective Cerebral ischemia would rapidly initiate structural and functional damages in brain, including blood-brain barrier disruption, inflammation, and angiogenesis. The purpose of present study is to investigate the effects of indomethacin, an agent that inhibits cyclooxygenase, on the inflammatory reaction after cerebral ischemia-reperfusion in transient middle cerebral artery occlusion(MCAO)rats and its possible mechanism. Methods Adult male SD rats weighed 250-250g were subjected to either sham surgery or middle cerebral artery occlusion (MCAO) for 2h of brain ischemia and 24h reperfusion. After 24h of reperfusion,the size of cerebral infarction and the neurological deficit were determined by the method of TTC (2,3,5-Triphenyltetrazolium Chloride) staining and Longa's score analysis.The contents of IL-8, IL-1?, TNF-? and MPO in brain tissue were assayed by ELISA. The expressions of ICAM-1 ande E-selectin were evaluated with Western-blot. Results It was observed that indomethacin (6 or 9mg/kg i.p pretreatment for 5d, once a day) significantly reduced cerebral infarct volume and ameliorated the neurological deficit (P

OBJECTIVE To investigate and analyze the application of prophylactic antibiotics in perioperative period in hospital and offer the scientific basis for reasonable usage and management of antibiotics through surveying the situation.METHODS Totally 120 cases under operation were investigated prospectively from Jan to Aug in 2007.RESULTS The rate of antibiotics usage was 100% among the 120 cases.40% of the patients received single antibiotic treatment,56% and 4% received 2 or 3 kinds of antibiotics combined therapy respectively.The rate of prophylactic usage was 80.3%,the rate of therapeutic one was 19.7%;50% of the patients treated with antibiotics had the duration of postoperative prophylaxis of 7 days or more,the longest one was 30 days.the antibacterials used in turns were cephalosporins,penicillins,lincomycin,macrolides and nitroimidazole.CONCLUSIONS The duration of antibiotic used after operation is too long and the rate of combined anti-infective drugs is too high.It means that their are some problems existed in prophylactic use of antibiotics during cardiovascular surgery at perioperative period in condition of extracorporeal circulation,it is necessary that the antibiotic administration should be standardized.

Objective To investigate the risk factors for nosocomial infections in rehabilitation department of a general hospital. Methods The infection rate, underlying diseases and infection sites were retrospectively reviewed in 1243 patients hospitalized in rehabilitation department of the Second Affiliated Hospital of Wenzhou Medical College from July 1, 2004 to June 30, 2008. Risk factors were determined by multivariate analysis with Logistic regression. Results The infection rate and the frequency of nosocomial infections in rehabilitation department were 18. 34 % (228/1234) and 21. 40 % (266/1243), respectively. Patients with spinal cord injury and those with cerebrovascular diseases accounted for 41.67% (95/228) and 31. 14% (71/228) of the total nosocomial infections, respectively. Urinary tract and lower respiratory tract were the frequent infection sites. The incidence of nosocomial infections was correlated with underlying diseases, age, length of stay, invasive operation, nutrition, sensory or movement disturbance and dysphagia. Conclusions Rehabilitation department has high nosocomial infection rate. Relevant risk factors should be carefully monitored to prevent or reduce the occurrence of the infections.

Objective To compare the clinical effect of penehyclidine hydrochloride and atropine in the treatment of acute organophosphorus pesticide poisoning.Methods 86 patients with organophosphorus pesticide poisoning were selected and randomly assigned to the observation group and the control group according to the digital table,43 cases in each group.The two groups were given conventional treatment,while the control group was treated with atropine,the observation group was given penehyclidine hydrochloride.The disappearance time of main symptoms, rescue success rate and adverse reactions of the two groups were observed.Results After salvage treatment, the rescue success rate of the observation group was 97.8%,which of the control group was 88.4%,the difference was statistically significant (x2=1.433,P<0.05).The disappear time of M like symptoms,N like symptoms and central nervous system symptoms in the observation group was significantly shorter compared with the control group (all P<0.05).The number of drugs,dosage,cholinesterase recovery time and hospitalization time between the two groups had statistically significant differences (P<0.05).The incidence rates of blurred vision,restlessness,heart rate and urinary retention in the control group were significantly higher than those in the observation group (all P<0.05).Conclusion Penehyclidine hydrochloride for acute organophosphorus pesticide poisoning can significantly reduce the incidence of symptoms,shorten the disappearance time of symptoms,reduce hospitalization time,improve the efficacy of rescue,reduce the incidence of adverse reactions, it is safe,effective and has great clinical significance.

Objective To explore the value of fascial tail sign at MR images in the detection of nodular fasciitis (NF). Methods A retrospective analysis of MR images was performed in 19 patients with pathologically proven NF of the soft tissue and 53 patients with a variety of other fibrous-predominant tumors. MR manifestations of all cases were reviewed by two experienced musculoskeletal radiologists using a single blind method. The presence of fascial tail on MR images were evaluated. ROC was used to assess the value of fascial tail sign in the detection of NF. Sensitivity, specificity, Youden index and area under ROC curve were calculated. The association between the presence of fascial tail sign on MRI and pathological classification of NF was analyzed by Pearson chi-square test for independence . Results Fascial tail was present in 17 cases (89.5%) of the study group and in 6 cases (11.3%) of the control group, respectively, yielding a sensitivity of 89.5%, a specificity of 88.7%, a Youden index of 0.782 and an area under ROC curve of 0.891. The fascial tail sign was significantly associated with NF (c2=39.294,P<0.05,r=0.594). Conclusions Fascial tail sign at MRI is a moderately specific and sensitive for the diagnosis of NF relative to fibrous-predominant tumors. It can be used in differentiate between NF and aggressive soft tissue tumors.
