PurposeTo explore the multislice CT (MSCT) and clinical manifestations of diaphragmatic hiatus hernia with hernial sac effusion, in order to improve its diagnostic rate.Materials and MethodsMSCT data were retrospectively analyzed for morphologies and clinical manifestations in 32 patients with diaphragmatic hiatus hernia and hernial sac effusion.Results32 patients included 21 males and 11 females (χ2=0.64,P>0.05). 25 patients were older than 60 years and 7 cases younger than 60 years (χ2=13.58,P<0.01). There were 27 cases with non-viscera hiatus hernia including 23 cases of combined fat-water hernia and 4 cases of simple effusion. 5 cases were of viscera type hiatus hernia (χ2=5.47,P<0.05). 28 cases showed ascites including 23 cases with non-viscera hiatus hernia and 1 case with viscera type hiatus hernia (χ2=9.56,P<0.01). The axial images from different levels of non-viscera hiatus hernia with liquid hernial sac demonstrated quasi-circular, meniscus, ringlike and teardrop shapes.Viscera type hiatus hernia and liquid hernial sac were found to be irregular shape . All patient sufferered from dysphagia, chest distress and epigastric discomfort.ConclusionThe increased pressure gradient between thorax and abdomen driving ascites into supradiaphragmatic hernial sac and clamping by hiatus may be the main mechanism. Quasi-circular, meniscus, ringlike andteardrop were the characteristic signs of diaphragmatic hiatus hernia with hernial sac effusion.

Objective To summarize the safety and efficacy of low dose of hepatitis B immunoglobulin (HBIG) for prevention of de novo hepatitis B infection after renal transplantation.MethodsThe clinical data of 138 patients who received renal transplantation without hepatitis B infection between January 2007 and June 2010 were retrospectively studied (study group).All the patients in study group were given low dose of HBIG injection before transplantation.The HBsAb titer was monitored regularly after transplantation,and the dosage of HBIG adjusted according to the level of the HBsAb titer.HBIG was implied to all patients in the study group for more than one year.The clinical data of 196 patients who received renal transplantation without hepatitis B infection between January 2004 and December 2006 served as the control group.These 196 patients were not treated with HBIG.The incidence of de novo hepatitis B infection,and acute rejection of these two groups was analyzed.The one-year graft and patients survival rate was also investigated.Results During the follow- up period of 12 months,only one case in the study group had de novo hepatitis B infection (0.7％) 6 months after renal transplantation,while 11 cases (5.6％) in the control group had de novo hepatitis B infection,in which 2 cases were died from acute hepatic failure.The incidence of de novo hepatitis B infection had statistically difference between the two groups (P＜0.05).The incidence of acute rejection in the study and control groups was 13.8％ and 17.3％ respectively (P＞0.05).The one-year graft and patient survival rate in the study and control groups was 96.4％ and 97.8％,and 90.3％ and 91.8％ respectively (P＜0.05).ConclusionLow dose of HBIG is effective and safe for prevention of de novo hepatitis B infection after renal transplantation.

OBJECTIVE:To prepare aspirin-β-cyclodextrin-PLGA microspheres,and control its quality. METHODS:Aspirin-β-cy-clodextrin inclusion complexes were firstly prepared,and then aspirin-β-cyclodextrin-PLGA microspheres were prepared by emul-sion-solvent evaporation method. The morphology and particle size of microspheres were detected,and entrapment efficiency and accu-mulative release rate were calculated. With entrapment efficiency as index,orthogonal test was adopted to optimize stirring speed,PVA concentration,PVA volume and feed ratio. RESULTS:The optimal formulation was as follows as stirring speed of 4 000 r/min,PVA concentration of 3%(g/100 ml),PVA volume of 30 ml,feed ratio of 1∶10. Prepared microspheres were round and smooth in appear-ance. Entrapment efficiency of the microspheres was (41.79 ± 1.09)%. The diameter were regular and ranged 0.5-127.5 μm. As drug-loaded microspheres degraded,the release of aspirin was slow and its accumulative release rate was 83%within 600 h. CONCLU-SIONS:Aspirin-β-cyclodextrin-PLGA microspheres are prepared successfully with regular morphology and good sustained-release.

Objective To investigate the effect of isolated carotid sinus perfusion with propofol on plasma endothelin and nitric oxide levels in diabetic rats.Methods Healthy adult Wistar rats weighing 180-220 g were used in this study.Diabetes mellitus was induced by intraperitoneal streptozotocin 30 mg/kg and confirmed by blood glucose ≥ 16.7 mmol/L.Thirty-six rats in which diabetes mellitus model was successfully established were randomly divided into 3 groups ( n =12):control group (group DC) ;low dose propofol group (group DP1 ) and high dose propofol group (group DP2 ).Another 36 non-diabetic rats were also randomly divided into 3 group ( n =12 each):control group (group NC) ; low dose propofol group group (group NP1 ) and high dose propofol (group NP2 ).After 30 min isolated carotic sinus perfusion with K-H solution (control groups),50 μmol/L propofol in K-H solution (low dose propofol groups) or 100 μmol/L propofol in K-H solution (high dose propofol groups),blood samples were taken for determination of plasma endothelin and nitric oxide concentrations.Results The plasma endothelin concentration was lower and nitric oxide concentration higher in groups DP1 and DP2 than in group DC,and in group DP1 than in group DP2 ( P ＜ 0.05).The plasma endothelin concentration was higher and nitric oxide concentration lower in group NPi than in group DP1,and in group NP2 than in group DP2 ( P ＜ 0.05 ).Conclusion Propofol can decrease endothelin level and increase nitric oxide level in diabetic or non-diabetic rats through local effect on carotid sinus,and the effect is stronger in diabetic rats than in non-diabetic rats.

Aim To investigate the effect and mecha-nism of valproic acid on neuroglobin expression, and the neuroprotective role of valproic acid against H2 O2-induced neurotoxicity. Methods Western blot, RT-PCR and luciferase assay were used to detect the pro-tein levels, mRNA levels and promoter activity of mouse and human neuroglobin induced by valproic acid. Luciferase assay was used to investigate the role of transcription factor CREB in the up-regulation of neuroglobin by valproic acid. MTT assay was used to evaluate the effect of valproic acid against H2 O2-in-duced neurotoxicity. Results VPA treatment marked-ly increased the protein levels, mRNA levels and pro-moter activity of Ngb in mouse N2 a cells and human SKNSH cells. CREB specific inhibitor KG501 or CREB dominant negative mutant KCREB attenuated VPA-induced Ngb promoter activity. VPA could pro-tect N2a cells from H2 O2-induced neurotoxicity. Con-clusion CREB mediates VPA-induced Ngb up-regula-tion, which may contribute to the neuroprotective effects of VPA in oxidative stress in neurons.
