Objective To investigate the effect of propofol on the heme oxygenase-1(HO-1)expression in rats with H_2O_2-mediated damage to cultured cardiac myocytes.Methods Primary cultured new-born rat cardiac myocytes were divided into 8 groups:control,H_2O_2 group,low dose propofol (LP) group,middle dose propofol(MP)group,high dose propofol(HP)group,LP +ZnPP Ⅸ group.MP+ZnPP Ⅸ group and HP+ZnPP Ⅸ group.The cells in all groups were incubated for 6 h.The concentration of malondialdehyde(MDA),activity of superoxid dismuase(SOD),mitochondria and Caspase-3,and the expression of HO-1 were determined.Results As compared with H_2O_2 group,the HO-1 expression,and the activity of SOD and mitochondria were significantly increased(P<0.05,P<0.01),and activity of Caspase-3 and concentration of MDA was decreased(P<0.05)in MP and HP groups.As compared with LP,MP and HP groups respectively.the HO-1 expression and SOD activity were significantly decreased and the concentration of MDA increased in LP+ZnPP IX,MP+ZnPP Ⅸ and HP+ZnPP Ⅸ groups(P<0.05,P<0.01),while Caspase-3 activity was significantly increased in MP+ZnPP IX and HP+ZnPP IX(P<0.05,P<0.01).Conclusion Propofol can protect cardiac myocytes against H_2O_2-mediated cytotoxicity in a dose-dependent manner,and increase the HO-1 expression,which may partly mediate cytoprotective effects of propofol.

Sepsis is a common desease with a high mortality in pediatric intensive care unit. The patho-genesis of sepsis remains unclear. Recent studies have found that extracellular histones play an important role in the incidence of sepsis. This review provides new ideas for the diagnosis and treatment of sepsis.

Total pelvic floor reconstruction is a minimally invasive and effective method for the treatment of pelvic organ prolapsed. It is a minimally invasive and effective method for the treatment of pelvic organ prolapsed, and it significantly improves the quality of life of patients. However, due to the complex anatomy of the pelvic floor, the requirements of clinical physicians and nursing is high, and related complications are easy to occur. This article introduces the observation and nursing care of the complications such as the bladder/rectum and nerve injury, the erosion of the mesh, the symptoms of the pelvic floor reconstruction, the pain or discomfort of the intercourse. Summary of the recent 10 years research results, to provide reference and guidance for clinical nursing work.

Acute traumatic coagulopathy (ATC) attacks suddenly with a rapid progress and has an extremely highly mortality.Of late years more and more relative studies have made a great progress on the pathogenesis,diagnosis and treatment of ATC.However,there are currently no medical guidelines for ATC.There are still some problems such as nonstandard treatment,outdated concept and so on in clinic.Based on the latest research progresses home and abroad,this paper expounds emphatically the first-aid and treatment of ATC in order to bring helps to the clinical doctors.

Objective: To compare the myocardial protection effect between off-pump coronary artery bypass(OPCAB)and on-pump coronary artery bypass. Methods: 70 patients were divided into 2 groups:off-pump coronary artery bypass(beating group,n=35), and cold blood cardioplegia solution group(cold group,n=35). There was no statistical difference in heart function, sex, age and weight before operation. Blood samples were taken for determine the serum concentration of creatine kinase MB isoenzyme (CK-MB) and troponin-T(cTnT) peri-operatively. Myocardial ultrastructure was also observed. Results: CK-MB, cTnT release in beating group during bypass and post-bypass was lower than that in cold group (P

Objective To explore the means of treating postoperative gastrointestinal fistulas in patients with severe acute pancreatitis(SAP). Methods A retrospective study was carried out on the clinical data of 28 cases of postoperative gastrointestinal fistulas(PGF) in patients with severe acute pancreatitis admitted in our department between 1996 and 1999.Results The amount of drainage decreased significantly by using somatostatin(SS) and growth hormone(GH). All the patients were recovered, the average disappearred time of the fistula was (52?16) days(24～227 days).85.7% of the fistula were cured by non operative treatment.Conclusions Non-operative treatment is suitable to most of SAP patients with PGF. SS and GH can accelerate the healing of gastrointestinal fistulas.
