AIM: To study apoptosis and the involved genes in malignant transformation of gastric carcinoma. METHODS: Apoptotic cell and apoptotic regulating gene p53,bcl-2,c-myc were detected in 46 cases with gastric carcinomas, 20 cases with precancerous lesions and 24 cases with normal mucosa in situ using TdT-mediated dUTP-biotin nick end labeling (TUNEL) technique and immunohistochemical stain. RESULTS: Apoptotic index in precancerous lesion(intestinal metaplasia and dysplasia) and gastric carcinoma were significantly higher than that in normal mucosa( P

AIM: To study the effects of Sini Decoction's effective component(SNDE) on myocardial apoptosis and ceramide content during myocardial ischemla/reperfusion. METHODS: The mice of Kunming species were randomly divided into 3 groups: control,myocardial ischemia/reperfusion and SNDE.After inducing myocardial ischemia/reperfusion injury of mice in vivo with pituitrin(Pit),myocardial SOD activity and MDA content were measured.DNA agarose gel electrophoresis and fluorescent stain of DAPI were done to check up apoptosis.The content of myocardial ceramide(?g/kg) was measured through HPTLC and scan of thin plate. RESULTS: The myocardium of model group has the phenomenon of DNA ladder.The apoptosis index and the ceramide content in model group were higher than those of control group(P

Objective To study the anti-myocardial ischemia-reperfusion injury effect of Sini Decoction's active fraction(SNDAF).Methods Experimental animals were randomly individed into normal,model,Sini Decoction(SND),and SNDAF groups.Rat hearts were perfused by the Langendorff method.The model of myocardial ischemia-reperfusion injury was reproduced by adjusting the flow of perfused liquid.The perfused liquid of normal and model groups was KH buffer saturated by oxygen.The perfused liquid with SND or SNDAF was mixed with KH buffer.The coronary flow and contract power of myocardium at 0 min of ischemia and 1,5,10,20,30,40,and 50 min of reperfusion were tested,respectively.The incidence of reperfusion arrhythmias(IRA) in the first 1 minute of reperfusion was calculated.Mice were given drugs by ig for 3 d and then myocardial ischemia-reperfusion models were established by ip pituitrin(20 U/kg).ECG of mice was recorded at 0—80 min after ip administration. SOD activity,and the contents of MDA and LA in myocardium of mice were measured.Results Both SND and SNDAF could reinforce myocardial contract and reduce the IRA in the first minute of reperfusion.SND had better effect on IRA than that of SNDAF.SNDAF had better effect on myocardial contract than that of SND.SND and SNDAF could significantly drop ECG J point raise induced by ischemia,and increase SOD activity,and decrease contents of MDA and LA significantly in ischemia myocardium.There were no significant difference between SND and SNDAF.Conclusion SNDAF could improve oxidative injury and suppress(ischemia) of myocardium,reinforce myocardial contract,and reduce the incidence of arrhythmias during(myocardia) ischemia-reperfusion.

AIM: To study the change of myocardial ceramide during myocardial ischemia/reperfusion and the relationship between ceramide and apoptosis and oxidative stress. METHODS: After inducing myocardial ischemia/reperfusion (I/R) injury in mice with pituitrin (Pit), myocardial SOD activity and MDA content were measured. DNA agarose gel electrophoresis and fluorescent staining of DAPI were done to check up apoptosis. The content of myocardial ceramide (?g/kg) was measured through HPTLC and scan of thin plate. RESULTS: The myocardium of I/R model group had the phenomenon of DNA ladder. Apoptosis index and ceramide content in I/R model group were higher than those in normal control group (P

AIM:To establish a microthrombus model by carrageenan (Ca)/ lipopolysaccharides (LPS) intraperitoneal injection in rats with hyperhomocysteinemia (HHcy) and endothelial dysfunction induced by L-methionine intake. METHODS: ① Male Sprague Dawley rats were randomly divided into 2 groups: control and endothelial dysfunction (HHcy) groups. L-methionine was administered by gavage in HHcy group for total 4 weeks. Purified water was administered by gavage in control rats. Plasma Hcy, NO and vWF were examined and the thoracic aorta were excised after 4 weeks of L-methionine treatment to evaluate endothelial function. ② Male Sprague Dawley rats were randomly divided into 3 groups to establish a microthrombus formation model with Ca/ LPS: control, microthrombus formation (Ca/LPS) and endothelial dysfunction plus mitoarothrombus formation (HHcy+Ca/LPS) groups. Control rats were injected with normal saline (NS). Ca/LPS rats were intraperitoneally injected with carrageenan (Ca) and followed by lipopolysaccharides (LPS) 16 h later. HHcy+Ca/LPS rats were intragastric gavaged by L-methionine for total 4 weeks, and then were injected with Ca/LPS in the same way as Ca/LPS group. Cruor parameters and platelet count were detected at 20 h after LPS or NS injection and the mesentery microcirculation was monitored. Plasma NO and vWF were also detected at 24 h after LPS or NS injection. RESULTS: ① Plasma Hcy concentrations and vWF level were significantly increased in HHcy group, while plasma NO content was significantly decreased compared with that in control group. Endothelial dependent relaxation (EDR) of aortic rings was significantly decreased in HHcy group, suggesting endothelial damage/dysfunction was induced by HHcy. ② Mesentery capillary was obviously blocked by microthrombus in Ca/LPS rats and was blocked more seriously in HHcy+Ca/LPS rats. Cruor parameter results suggested that Ca/LPS rats were in hypercoagulable phase and HHcy+Ca/LPS rats were in hypocoagulable phase at 20 h after LPS injection. Platelet count and plasma NO content in HHcy+Ca/LPS group were significantly decreased, while plasma vWF level was significantly increased compared with Ca/LPS group. CONCLUSION: L-methionine intake induces severe HHcy and causes endothelial dysfunction in rats. Microcirculation dysfunction and microthrombosis can be caused by Ca/LPS intraperitoneal injection and may be aggravated by endothelial dysfunction.

Objective To retrospectively analyze the engraftment, transplant-related complications and survival after unrelated cord blood transplantation (UCBT) in patients with hematologic malignancies. Methods Fifty consecutive patients with hematological malignancies (median age, 19 years; median weight, 53 kg) were treated with UCBT in single center from April 2000 to August 2009. Thirty-nine patients were high-risk or refractory. Double UCB grafts were used for 26 patients, while single UCB graft for 24 patients. Myeloablative conditioning was given to 45 cases and non-myeloablative regimens to 5 cases. All patients were given a combination of cyclosporin A (CsA) and mycophenolate mofetil (MMF) for graft-versus-host disease (GVHD) prophylaxis. Results The median total nucleated cell (TNC) dose was 4.0 (range, 1.95-16.24)×10~7 TNC/ kginfused, and CD34~+ cell dose was 2.74(range, 0.67-29.28)×10~5/kginfused. Forty-two of 50 patients acquired engraftment with implantation rate being 86%. The median time to engraftment (absolute neutrophil count>500/mm~3 and platelets 20 000/L) was 19 and 34 days. The cumulative incidence of neutrophil engraftment by day 42 was 86.3%(95% confidence interval [CI] 0.769-0.957); the cumulative incidence of platelets engraftment by day 120 was 72.3% (95% CI 0.620-0.821). Twenty cases developed acute GVHD, and the incidence of acute GVHD of grades Ⅲ/Ⅳ by day 100 was 7.1%. The incidence of chronic GVHD within 2 years was 17.4%. During a median follow-up period of 22 months (range 4-116), Overall 6-month, 1-year and 2-year survival rate was 66.2%(95% CI 0.590-0.734), 57.4%(95% CI 0.496-0.652), 54.2%(95% CI 0.462-0.622), respectively. For the patients with non-advanced hemotologic malignancies, 6-month, 1-year and 2-year survival rate was 73.2% (95% CI 0.659-0.805), 66.1% (95% CI 0.579-0.743), and 62.2% (95% CI 0.542-0.682) respectively. Five cases relapsed. The cumulative incidence of relapse within 2 years was 16.2% (95% CI 0.099-0.225). Twenty-one cases died mainly due to infection. Conclusion UCBT could be safely and effectively used for adult patients with hematologic malignancies.

Objective To investigate the efficacy and safety of posaconazole in the prophylaxis or salvage treatment of invasive fungal disease (IFD) in patients with hematological diseases.Methods 25 patients with hematological diseases receiving posaconazole treatment from Feb 2014 to Feb 2015 were analyzed retrospectively.The patients' average age was 32.6 years old (16-64 years old).18 patients received posaconazole for IFD prophylaxis, and 7 patients for IFD salvage treatment.Results 18 patients receiving posaconazole for IFD prophylaxis had no clinical manifestation of IFD (that is no case of breakthrough fungal infection) during treatment or in the 12 weeks after treatment, and the average prophylaxis period was 21 d (14-35 d).Among 7 patients receiving posaconazole for IFD salvage treatment, 6 patients were effective, including 4 cases cured and 2 cases effective.There were no obviously side effects of posaconazole in these patients.Conclusion Posaconazole has good clinical response for IFD in the hematologic diseases patients whether in prophylaxis or in salvage treatment.

Objective To analyze the treatment efficacy and safety of a modified GMALL protocol for adult acute lymphoblastic leukemia (ALL). Methods Data of 37 patients with newly diagnosed adult ALL treated with a modified GMALL protocol from January 2005 to December 2009 were retrospectively analyzed,and compared with that of 44 patients treated with an in-house conventional protocol at the same period.Results The complete remission (CR) rate was 89.2 %(33/37) treated with modified GMALL protocol. The cumulative overall survival (OS) rates at 1 year, 2 years, 3 years and 4 years were 77.5 %, 48.0 %, 40.0 %and 40.0 %, respectively. The main adverse events were grade 3 or grade 4 hematological toxicities and infections which were easily managed, and the treatment-related mortality rate was low. The OS of modified GMALL protocol was superior to that of the conventional protocol. Conclusion The modified GMALL protocol has a satisfying effect and the adverse events can be tolerated for adult ALL, so its clinical application can be encouraged.
