BACKGROUND: The abnormal apoptosis of intestinal epithelial cells is the main cause of intestinal mucous membrane injury during ischemia reperfusion. Shenfu injection has good therapeutic effect on intestinal mucous membrane injury. OBJECTIVE: To investigate the influence of shenfu injection medication on intestinal apoptotic epithelial number, apoptosis-related caspase-3 and Bcl-2 gene expression, as well as the level of tumor necrosis factor (TNF)in intestinal ischemia reperfusion rat model.DESIGN: Randomized controlled experiment.SETTING:Department of Anesthesia, Renmin Hospital of Wuhan University.MATERIALS:This experiment was carried out in the laboratory of the Department of Anesthesia, Renmin Hospital of Wuhan University, between December 2002 and June 2003. Totally 24 healthy SD rats of clean grade were randomized into blank control group, intestinal ischemia reperfusion (IR) group and shenfu injection group with 8 rats in each group.METHODS: Rats in each group were anesthetized with intraperitoneal injection of ethyl carbamate at dosage of 1mg/kg; then in intestinal IR group and shenfu injection group rats' superior mesenteric artery was occluded with vascular clamp for 1 hour before 2-hour reperfusion,which was not conducted in blank control group. Rats in shenfu injection group were intravenously injected with shenfu injection at 30 minutes before occlusion at dose of 0.02 mL/g, which was replaced by the same volume of physical saline in blank control group and intestinal IR group. The expression of caspase-3 and Bcl-2 protein and cell apoptosis wee detected.MAIN OUTCOME MEASURES: ① Comparison of apoptotic index between groups. ② The expression of caspase-3 and Bcl-2 gene in rat intestinal epithelium. ③ Comparison of TNF content in intestinal mucous membrane homogenate between groups.RESULTS: Totally 24 rats were included in this experiment and all ehtered the result analysis. ①Comparison of apoptotic index between groups:The apoptotic index was obviously lower in shenfu injection group than in intestinal IR group, but higher than in blank control group [(7.75-±1.89)%,(28.25±8.50)%, (4.25-±2.63)%, P ＜ 0.01]. ② The expression of caspase-3 and Bcl-2 gene in rat intestinal epithelium: caspase-3 expression was lower in shenfu injection group than in intestinal IR group, but higher than in blank control group [(0.211 6±0.087 5), (0.354 7±0.077 8), (0.194 1±0.057 4) A,P ＜ 0.01, P ＞ 0.05]; Bcl-2 expression was remarkably higher in intestinal IR group than in blank control group (P ＜ 0.05), but obviously reduced in shenfu injection group compared to intestinal IR group (P ＜ 0.01). ③ TNF content of intestinal mucous membranehomogenate in each group: TNF content was remarkably higher in intestinal IR group than in blank control group and shenfu injection group [(189.7±56.3), (38.6±10.4), (47.5±l8.7)mg/L,P ＜ 0.01], and basically the same in shenfu inj~tion group and blank control group (P ＞ 0.05).CONCLUSION: Shenfu injection can suppress intestinal epithelial apoptosis by reducing TNF content and caspase-3 e.pression as well as upregulating the expression of Bcl-2 gene during ischemia reperfusion, thereby attenuating ischemia reperfusion injury of intestinal mucous membrane.

ObjectiveTo investigate the effects of pre-infusion of hypertonic sodium chloride hydroxyethyl starch 40(HH40)injection in prevention for transurethral electroresection of the prostate syndrome(Tuns).MethodsSixty patients with benign prostate hyperplasia(ASA)grades Ⅱ toⅢwere recruited in the study and randomly divided into two groups,one injected intravenously with HH40 at dose of 5 ml/kg by drip after sursical operation a8 experiment and the other injcoted with the same volume of Ringer's solution as control Mcan arterial pressure,heart rate,saturation of blood oxygen(SaO2)and central venous pressure were monitored for all the patients.In addition.serum concentrations of sodium,potassium,chloride and serum osmolality were determined before(T0)and 30 min(T30)and 60 min(T60) after operation,respectively,as well as pH valRe and partial pressure of carbon dioxide(PgCO2)in the gastric mucosa were determined by a Tonocap monitor.Occurrence of TURS and use of atropine,ephedrine and rinse solution were documented.Resuits TURS occurred in four patients in the eontrol group during surgical operation,whereas uo TUns occurred in experimental group.Serum sodium concentration was (126.5±13.3)mmoL/L at T60 in control group,significantly lower than that in experimental group(P＜0.05),while intragastric pH value and PgC02 level were(7.26±0.04)and(54±9)mm Hg[(7.2±1.2)kPa],respectively in controls,significantly higher than those in experimental group(P＜0.05).ConclusionsPre-infusion with HH 40 can improve tissue perfusion and prevent effectively from TURS in patients with transurethral electroresection of the prostate.

Objective To investigate the risk factors of symptomatic vasospasm after aneurysmal subarachnoid hemorrhage and evaluate the effect of lumbar drainage of cerebrospinal fluid on vasospasm.Methods In this retrospective controlled-cohort study, 175 patients with aneurysmal subarachnoid hemorrhage met our study criteria between January 2012 and December 2013.By multi-factor regression analysis, gender, age, Hunt-Hess grade, modified Fisher grade and lumbar drainage were analyzed.The outcomes were assessed by the presence or absence of symptomatic cerebral vasospasm and vasospasm-related infarction, and the mean days of hospital stay and score of Glasgow Outcome Scale at 1-month follow-up.Results Several factors affected the prognosis of subarachnoid hemorrhage.Lumbar drainage was a protective factor of symptomatic cerebral vasospasm (OR =0.243, 95％ CI: 0.119-0.497) and vasospasm-related infarction (OR =0.305, 95％ CI: 0.154-0.604).The patients with lumbar drainage had higher score of Glasgow Outcome Scale (P ＜ 0.05).But the patients with lumbar drainage had longer hospital stay (P ＜ 0.05).Conclusions Lumbar drainage of cerebrospinal fluid after aneurysmal subarachnoid hemorrhage markedly reduced the risk of symptomatic cerebral vasospasm and improved outcome.

Objective To investigate current status of schistosomiasis control system at the county level and make recommendations to improve the infrastructure adapting to the prevalent condition of the disease. Methods Through pertinently sampling and semi-quantitative questionnaire among the professional workers, experts and administrators in schistosomiasis control, the primary weaknesses involved in the management system and human resources were analyzed. Results 380 questionnaires were distributed, 33 out of 40 were returned from experts/administrators and 285 out of 340 were received from the professionals. In general, the participants acknowledged the effectiveness of the mechanism on anti-schistosomiasis campaign during the past 40 years. It was found that lack of funds for schistosomiasis control and the poor administrative model of anti-schistosomiasis activities were the main barriers to the control. About half of the participants agreed that the policy about merging the county level anti-schistosomiasis facilities into the Center for Disease Prevention and Control (CDPC) system. The study also showed an inbalanced distribution of the manpower for schistosomiasis control across the endemic regions. The dropout rate of human resources was high due to the poor management and welfare. Conclusion Reforms on the management model should be performed and multiform compensation system should be built in accordance with the prevalence and trends of schistosomiasis.

ObjectiveTo assess revascularization and vessel anastomosis in digital replantations with DSA.MethodsTwelve cases of digital replantations underwent digital subtract angiography during 2 to 4 days after fingers reattachment. The vessel anastomosis,hemodynamics,stenosis and discontinuation were investigated.The unobstructed and smooth anastomosis was suggested as early stage survival of the reattached fingers,the spasm and stenosis of the reattached vessels were considered as mild vascular crisis,and the discontinuation of hemodynamics were indicated as severe vascular crisis.ResultsThe total 27 vessels were clearly displayed on DSA.Of these vessels,23 vessels were unobstructed and smooth,all digits were survived.Diagnosis coincidence of early stage survival was 100%(23/23). Two vessels were obstructed,which were testified having thrombus by operation research.The other 2 vessels were spasm,the digits were also survived ultimately by expectant treatment.All 4 abnormal vessel anatomosis were found by DSA.Conclusion DSA is important modality in assessing revascularization and blood circulation for digital replantations,guiding in dealing with the vascular crisis,and in predicting early stage survival of the reattached digits.

Objective To screen the glycoproteins as biomarkers for intracranial aneurysm (ⅠA) in cerebrospinal fluid (CSF) and evaluate the specificity and sensitivity of the biomarker candidates.Methods A complementary proteomic approach integrated with multidimensional chromatography was employed to simultaneously measure relative changes in the gylcoproteins of cerebrospinal fluid (CSF) obtained from patients with ruptured ⅠA (RIA) and unruptured ⅠA (UIA) compared to the healthy controls (HC) and disease controls (DC).One protein-receptor tyrosine kinase Axl with a unique change in RIA was validated in CSF and plasma.The sensitivity at 95％ specificity of Axl in CSF and plasma was evaluated with receiver operating characteristic curve (ROC curve).Results Firstly,a total of 294 glycoproteins were identified in human CSF with believable evidence.Secondly,the proteomic findings showed the quantitative changes in RIA and UIA as compared to HC and DC.Of 294 identified CSF proteins,59,24 and 33 proteins displayed quantitative changes unique to RIA,UIA or IA,respectively.At last,one of these unique proteins-receptor tyrosine kinase Axl with unique increase in RIA was confirmed both in CSF and plasma.ROC curve analysis showed that the sensitivity at 95％ specificity of Axl in CSF to differentiate RIA from UIA was 60％.When compared to CSF,the sensitivity at above setting in plasma to differentiate RIA from HC was 40％ and to differentiate RIA from UIA was 25％.Conclusions A glycoprotein biomarker Axl might be used as a promising biomarker to predict the rupture of ⅠA.The further investigation of the relations between Axl and IA formation as well as rupture might help to elucidate the underlying pathogenesis and find new therapeutic targets.
