Objective To summarize perioperative care and effect of surgical treatment of total anomalous pulmonary venous connection (TAPVC) in newborns and babies within 6 months.Methods From September 2001 to May 2013,ninetytwo consecutive patients with TAPVC received surgical correction under cardiopulmonary bypass (CPB) with moderate or deep hypothermia.The anatomic subtype included supracardiac type 48,intracardiac type 36,infracardiac type 6 and mixed type 2.There were 36 newboms.Pathological diagnosis was made by echocardiogram,computerized tomography and operative findings during operation.The option of procedure was determined by findings.Respirator assisted breathing after operation and cardiac function was maintained by a variety of positive inotropic drugs,to prevent the happening of the pulmonary hypertension crisis.Results Severely low cardiac output syndrome occurred in 8 patients and they died within 24 hours after operation.The remaining cases postoperative recover smoothly and receive postoperative follow-up about 1 month to 12 years,3 cases of postoperative pulmonary vein stenosis (PPVS) occurred.Conclusion Total anomalous pulmonary venous connection should be surgical treatment as soon as possible with satisfied effect.The key of perioperative care is maintenance of left heart function,negative balance of liquid,prevention and treatment of pulmonary hypertension.

AIM: To study the effect and mechanism of chlorophyllin (CHL) inhibiting HT29 cells. METHODS: IC 50 value and growth curve of HT29 cells were detected with MTT method. Apoptosis was detected with Wright-Giemsa staining, FCM and DNA electrophoresis. Telomerase was detected by PCR-ELISA, and protein and mRNA expression of COX-2 gene were detected through RT-PCR and Western blot. RESULTS: CHL inhibited the growth of HT29 in a dose-dependent manner. CHL blocked HT29 cells in G 1 phase but did not induce apoptosis. Different concentration of CHL inhibits the expression of telomerase and COX-2 in HT29 cells. CONCLUSION: CHL inhibits the growth of HT29 cells by inhibiting the expression of telomerase and COX-2 and blocking cells in G 1 phase. [

ObjectiveTo study neural protective effect of combined medication with nimodipine and mannitol on injury of cerebral ischemia-reperfusion for screening the better medication method in acute cerebral ischemia-reperfusion. MethodsA model of cerebral ischemia-reperfusion was performed by clipping bilateral common carotid artery of rats with vago- and releasing them 3 hours later. 40 Wistar female rats within 1 month were divided into 5 groups randomly with 8 rats each: model group (no use of medicine), nimodipine group(0.2mg/kg), mannitol group(0.5g/kg), nimodipine and mannitol group, sham-operated group (no use of medicine and no clipping process). The changes of SOD and MDA in brain tissue were measured 24 hours after cerebral ischmic reperfusion in all groups. At the same time pathologic study was performed to compare the different groups.ResultsThere were significant differences between nimodipine and mannitol group and other groups in changes of SOD, MDA and pathological changes(P<0.01). Conclusions Combined medication with nimodipine and mannitol is the better way to protect brain tissue from acute cerebral ischemia-reperfusion than other way in present experiment, by synergistic action.

OBJECTIVETo study the effect of rhubarb in treating patients with systemic inflammation reaction syndrome (SIRS) and its mechanism.

METHODSThe 40 patients with SIRS in the treated group were treated with conventional treatment plus rhubarb powder orally or by nasal feeding, the 38 patients in the control group were treated with conventional treatment alone. Serum tumor necrosis factor-alpha (TNF-alpha) was determined by ELISA during the admission and the 3rd day after admission, C-reactive protein (C-RP), complement 3 and 4 (C3, C4) were also determined by auto-scattering turbidimetric quantitative analysis. The parameters were compared between groups and with normal control group.

RESULTSCure rate in the treated group was significantly higher than that in the control group accompanied with lesser occurrence of multiple organ dysfunction syndrome (MODS) and lower mortality. Serum TNF-alpha, C-RP, C3 and C4 in the SIRS patients were increased during admission, which were significantly higher than normal control, but these parameters would be reduced together with the alleviating of symptoms after treatment, particularly after rhubarb treatment.

CONCLUSIONRhubarb could improve the prognosis of patients with SIRS, its major mechanism is that rhubarb has the antagonizing effect against inflammatory cytokines and complements.
