Objective To study the pathology mechanism of vascular dementia(VD)rats and study the effect of Bushenxingnao(BSXN)prescription on cerebral neurocyte apoptosis.Method Experimental VD model rats were caused by clipping two side of total artery in neck repeatedly and to examine cerebral neurocyte apoptosis with TUNEL.Results Both the high and low dose BSXN abated excitatory toxic infury and inhibit neurocyte apoptosis after ischemia-refusion.Conclusion BSXN prescription can repress cerebral neurocyte apoptosis,to abate its excitatory nerotoxicity,to protect cerebral neurocyte,which may be one of the mechanisms of to treating the lesion.

Objective To explore the efficacy of liver retransplantation for hepatocellular carcinoma (HCC) patients with or without HCC recurrence.Method 131 cases of retransplantation performed between 2003 and 2012 were analyzed retrospectively.Their first and second liver transplantations were both performed in our hospital.Diagnoses of their primary diseases before transplantations were confirmed pathologically after the first transplantation.Patients were divided into two groups in terms of benign causes and HCC.Results Sixty cases were fallen into benign disease group and 65 cases into HCC group.The proportions of main causes of retransplantation were similar between two groups.The graft survival rate of early retransplantation (retransplantation performed within 30 days after the first transplantation) and late retransplantation (retransplantation performed beyond 30 days after the first transplantation) was calculated and compared respectively due a great difference in survival rate between the two phrases.The deaths of HCC patients with HCC recurrence before retransplantation were more than those without HCC recurrence (P＜0.01) and benign disease group.The 5-year cumulated survival rate was close between HCC patients without recurrence before retransplantation (51.0％) and benign disease group (51.8％).Conclusion The retransplantation after HCC recurrence has an unacceptable prognosis.The survival rate was similar between patients without HCC recurrence and patients with benign diseases.HCC patients without recurrence should not be restrained from retransplantation just for the HCC history.

objective To investigate the clinicopathological features of mini-cancer of the stomach. Method In this study,out of 296 early gastric cancer cases there were 34 cases of early gastric cancer in which tumor diameter was≤10 mm,among those there were 5 cases with tumor size≤2 mm and 29 cases of the size 2～10 mm. Result Mini-cancer accunted for 2% of all early gastric cancers in this series:All these mini-cancers were of intramucosal cancer(100%),while that took up to 45%in control group in which tumors were between≥2 mm and≤10 mm:Tumors were high or moderately differentiated pathologically in 100%of mini-cancers and 55%in control group.None of mini-cancer patients had lymph node metastasis,however,1 of 29 patients in control group had lymph node metastasis.Both groups had no blood vessel and lymphatic vessel invasion:The differentiation concordance rate between superficial lesions and invasive fronts in mini-cancer was 100%,higher than 86%in control group. Conclusion Gastric mini-cancer is usually of high differentiation,low tumor invasion and low rate of lympy node metastasis than control group.Endoscopic therapy is applicable for most gastric mini-cancers.

Objective To assess the clinical application of Cylex ImmuKnow assay in patients with renal dysfunction after liver transplantation for individualized immunosuppressive therapy.Method Twenty adult patients undergoing liver transplant between January 2009 and December 2011 received regular ImmuKnow assay monitoring combined with determination of serum tacrolimus trough concentration to guide immunosuppressive regimens,all of whom showed sustained renal dysfunction 6 months after transplant with normal and stable liver function.Clinical data were collected to observe the changes of renal function in those patients after treatment.Results The recipients were followedup for 15-54 months,received ImmuKnow assay 61 times and the results fluctuated 33-943 μg/L [median 282 μg/L,interquartile range (IQR) 267 μg/L].After ImmuKnow monitoring,serum creatinine level in patients was decreased significantly from median 151.8 μmol/L with IQR 44.9 μmol/L to median 114.9 μmol/L with IQR 35.3 μmol/L (Z =-3.845,P =0.000),and estimated glomerular filtration rate (eGFR) was increased significantly from median 0.746 mL/s with IQR 0.025 mL/s to median 1.005 mL/s with IQR 0.454 mL/s (Z =-3.771,P =0.000).ImmuKnow results showed a linear correlation with the white blood cell count in patients (Spearman correlation coefficient r =0.429,P =0.001),but no linear correlation with the patients' age,primary disease before transplantation,postoperative time,serum tacrolimus trough concentration,lymphocyte count,CD3+ T lymphocyte count,CD4+ T lymphocyte count or CD4+/CD8+ T lymphocyte ratio (P＞ 0.05).Conclusion Cylex IrmmuKnow assay can be applied in patients with renal dysfunction after liver transplantation for individualized immunosuppressive therapy monitoring,which is of certain clinical value.

Objective To investigate the relationship between activation of gliacytes , mitogen-activated protein kinase (p38MAPK) and neuronal apoptosis after microinjecting aggregated Aβ25-35 into hippocampus.Methods The model was established by using stereotaxic technique to inject 10μg aggregated Aβ25-35 into dorsal hippocampus in rats .The rats were grouped as the control , vehicle and model groups .Immunohistochemistry and Western blotting were used for detection of activation of microglia(MG), atrocytes (AS) and expression of p-p38MAPK in the hippocampus.ELISA was used to evaluate the level of TNF-αand IL-1β.The survival neurons were observed by Nissl staining and the apoptotic neurons were identified by tunnel staining .Results Expression of ox-42, GFAP, p-p38MAPK were up-regulated in hippocampus, as well as TNF-α、IL-1β, which reached a highest value on the 7th day after injection of Aβ25-35.However, the number of neuron with Nissl positive decreased gradually , and the tunnel positive neurons increased highly and reached a peak value on the 7th day.There were significant differences between the control and vehicle group ( P <0.01). Conclusion Apoptosis of the neuron caused by Aβ25-35 injection may result from activation of gliacytes , p38 MAPK and increase of TNF-αand IL-1βlevel.

Objective To identify the changes of anti-HBs titers of patients with hepatitis B virus (HBV)-related diseases in the early stage (within the first week) post-liver transplantation (LT) and analyze their influencing factors.Method A total of 26 patients were enrolled in this study.They were all positive for HBsAg pre-LT and received the prophylaxis of lamivudine in combination with intravenous hepatitis B immunoglobulin (HBIG) in the first week post-LT.The titers of anti-HBs were detected daily in blood and drainage fluid every day in the first week post-LT.If the anti-HBs titers were greater than 1000 IU/L,blood and drainage were diluted,then detected again.Result The titers of anti-HBs in HBV-DNA negative groups,low HBsAg groups,and HBeAg negative groups were higher than those in the HBV-DNA positive groups,high HBsAg groups and HBeAg positive groups in the first five days post-LT.The median titer of anti-HBs in drainage fluid was 181.60 IU/L (0.00-968.50 IU/L).And the titer of anti-HBs in drainage fluid was correlated with anti-HBs titers in blood at the same time (r =0.927,P =0.000).The amount of anit-HBs calculated in drainage fluid was very high,but it fluctuated in a wide range (0.00-908.55 IU).Conclusion In the early stage post-LT,patients in high risk groups should receive higher doses of HBIG to maintain safe levels of anti-HBs,while the lower doses of HBIG are enough to the patients in low risk groups.Furthermore,the anti-HBs titers in blood aren't affected by the anti-HBs loss in drainage fluid.

Objective To evaluate the effect of aged cadaveric donor liver on long-term survival of liver transplant recipients.Methods Patients who underwent first time liver transplantation from cadaveric donor aging above 40 years were studied.Those patients were divided into donor age ＜ 50 group and age ≥ 50 group.Data for donor graft,recipient perioperative condition as well as long-term survival of recipients were compared between the two groups.Results There were 21 recipients receiving liver graft from a donor aging ≥ 50 (54.6-± 3.9) years.58 cases were given a liver graft from a donor aging ＜ 50 years (42.6 ± 2.9).The overall donor graft conditions were not different between the two groups (P ＞ 0.05).However,the median amount of operation time in donor age ≥50 group was longer than that in age ＜ 50 group (9.5 h vs.8.0 h,Z =-1.994,P =0.046).Median red blood cell (RBC) transfusion volume was greater in the age ≥50 group than that in age ＜50 group (1 000 ml vs.800 ml,Z =-2.593,P =0.010).During the follow-up,graft survival rates in 1,3 and 5 years were 74％,55％,55％ in donor age ≥50 group and 87％,66％,63％ in donor age ＜ 50 group,respectively (Z =0.903,P =0.342).Conclusions Use of aging cadaveric donor liver expandes donor pool,and is as well as safe,not hindering in graft's long term functions.

Objective To investigate the prognosis of liver retransplantation in patients with transplanted liver function failure caused by viral hepatitis recurrence.Methods From January 20th 2003 to November 20th 2012,the clinical data of 215 patients with liver retransplantation were retrospectively analyzed.The survival of transplanted liver of 18 cases with liver retransplantation because of hepatitis recurrence (eight cases of hepatitis C and 10 cases of hepatitis B) was compared with that of 115 cases with liver retransplantation for biliary complications.The dysfunction of transplanted liver after first transplantation and the survival after second liver retransplantation of patients with hepatitis C recurrence were compared with those of patients with hepatitis B recurrence.The prognosis analysis was compared by survival curves made by Kaplan-Meier method.Results Biliary complications were the most common reason in 215 patients with second liver retransplantation and which accounted for 115 cases (53.5 ％).Eighteen cases were hepatitis recurrence (8.4 ％).There was no significant difference in survival rate of the second transplanted liver between patients with hepatitis recurrence and biliary complication (P =0.543).The dysfunction of transplanted liver occurred at early stage (in three months) after first liver transplantation in part of patients with hepatitis C recurrence.The dysfunction of transplanted liver almost all occurred two years after first liver transplantation in patients with hepatitis B recurrence.Among eight patients with hepatitis C recurrence,the second transplanted liver of five cases survived more than one year.All the second transplanted liver of 10 patients with hepatitis B recurrence survived more than one year.There was no significant difference between them (P =0.060).Conclusions The prognosis of liver retransplantation in patients with hepatitis recurrence is similar with that of patients with biliary complications.The prognosis of liver retransplantation in patients with hepatitis B recurrence is good.
