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

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.

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.

Object To study the immunomodulatory effects of theasinesin (TS) on human peripheral blood mononuclear cells (PBMC) in vitro. Methods The proliferation response of lymphocytes and IL 2 production of human PBMC were detected by MTT method. IL 2R expression was determined by immunocytochemistry and indirect immunofluorescence. The intracellular cAMP level was assayed by radioimmunoassay. Results 50, 150, 500 ?g/mL TS could enhance phytagglutinin (PHA) induced human PBMC proliferation in a dose dependent manner. The IL 2 production and IL 2R expression of PHA activated PBMC were increased markedly under the presence of TS. TS also decreased cAMP level of PBMC and intensively weaken the cAMP upregulating effect of prostaglandin E 1 (PGE 1). Conclusion TS possesses a potential immunoenhancing effect which might be made by decreasing the cAMP level of PBMC, promoting IL 2 production and IL 2R expression.

AIM: To study the effects of theasinesin(TS) on proliferation and apoptosis of murine lymphocytes. METHODS: MTT method was employed to investigate the proliferatory response of murine splenocytes. Cellular morphological observation, DNA agarose gel electrophoresis and flow cytometry analysis were used to study the effects of TS on apoptosis of murine thymocyte and splenocyte. RESULTS: 50,150 and 500 mg?L -1 TS could markedly promote ConA-induced splenocyte proliferation in mice. In the cellular morphologic observation and DNA biochemical analysis, murine thymocytes cultured for 20 h in vitro showed keryopyk-nosis, condensation of cell, typical "ladder" on gel electrophoresis and typical apoptotic peak (AP) by FACS analysis. After treatment with 50, 150 and 500 mg?L -1 TS , DNA ladder and apoptotic peak were decreased gradually and apoptotic rates were reduced to 12.14%, 9.49%, 6.71% respectively from 19.87% in control group. But the apoptosis of murine splenocytes induced by 10 -5 mol?L -1 DEX was not affected by TS. CONCLUSION: TS can significantly promote splenocyte proliferation in mice and has an inhibitory effect on spontaneous apoptosis of murine thymocytes.
