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.

OBJECTIVETo study the clinical effect of combination of kurarinone (KR) and interferon a-lb (IFNalpha-1b) in treating chronic hepatitis B.

METHODSOne hundred and forty-six patients with chronic hepatitis B were randomized into four groups. Under the basic conventional treatment, additional KR combined IFNa-lb was given to Group A, IFNa-lb to Group B and KR to Group C while none was given to Group D. The therapeutic course for them was 6 months and succeeded with 6 months of follow-up. Changes in liver histology, expression of transforming growth factor beta (TGF-beta) in liver tissue, and serum levels of TGF-beta, hyaluronic acid (HA), laminin (LN), collagen type IV (IVC), precollagen III (PCIII), as well as the negative conversion rate of HBeAg and HBV DNA, and normalization rate of alanine transaminase (ALT) before and after treatment were observed by immuno chemical method, RIA and ELISA.

RESULTSAfter treatment, in Group A, the scores of liver fibrosis and all the above-mentioned indexes significantly lowered, as compared with those in Group B and C, the difference was significant (P<0.05 or P<0.01). The negative conversion rate of TGF-beta in liver tissue was in accordance with the dynamic change of liver fibrosis. Comparison between Group B and C in those aspects showed insignificant difference (P >0.05).

CONCLUSIONKR combined with IFNalpha-1b shows better effect in treating chronic hepatitis B than that of using either of the two alone.

Objective To investigate the relationship between serum uric acid (UA) level and abdominal obesity or metabolic syndrome (MS).Methods A total of 875 subjects,with 350 males and 525 females,aged 40-65 years old,were enrolled in this study.The clinical and biochemical data were collected and MRI was used to assess the visceral and subcutaneous adipose tissues.The relationships between UA level and abdominal obesity or MS were analyzed,and the cut-off values of UA for abdominal obesity and MS were determined.Results Raised risks of abdominal obesity (OR =4.35,95％ CI 1.91-9.90 in males; OR =5.44,95％ CI 2.41-12.31 in females) and MS (OR =4.47,95 ％ CI 2.08-9.62 in males; OR =11.62,95％ CI 3.43-39.37 in females) were observed with the increase of UA level.The multiple logistic regression analysis showed that UA was an independent risk factor for hypertriglyceridemia (OR =2.23,95％ CI 1.02-4.87 in males ; OR =3.04,95％ CI 1.49-6.23 in females) in all subjects and for abdominal obesity(OR =3.23,95％ CI 1.32-7.91) and hypertension (OR =2.35,95％ CI 1.37-4.05)in the females.Among the females,the regression line analyzed by simple correlation indicated that the UA level of 244.0 μmol/L was corresponded to the visceral adipose tissue area of 80 cm2.The optimal cut-off point of UA for the diagnosis of MS was 258.8 μmol/L determined by the receiver operating characteristic curve.Conclusions The level of UA is closely correlated with abdominal obesity and MS in the middleaged Chinese.The elevated UA level is an independent risk factor for abdominal obesity and MS in the female.

Objective To summary therapeutic method for delayed portal vein thrombosis after liver transplantation. Methods In 3100 cases undergoing cadaveric whole liver transplantation in a single center, there were 12 cases of delayed portal vein thrombosis after liver transplantation.Average occurring time was 29. 8 months after liver transplantation. Among these 12 patients, 2 cases were complicated with severe biliary complication (intrahepatic stricture) , 2 cases presented with liver failure of transplanted liver, and one case had portal vein compression by hepatic hilum tumor under the image examination, who received liver re-transplantation; two patients presented upper gastrointestinal bleeding, and they experienced endoscopic ligation and sclerotherapy respectively; the rest five patients without any clinical presentation were subjected to anticoagulation and antiplatelet therapy. Results Among 12 cases, 8 patients survived by the time of follow-up, including two patients undergoing re-transplantation; one patient lost follow-up. The liver function tests of the patients who survived were all normal. Conclusion The individualized therapeutic methods should be adopted for the patients with delayed portal vein thrombosis after liver transplantation.

ObjectiveTo investigate the effect of living donor right liver graft transplantation (LDLT) with middle hepatic vein (MHV) on the early congestion and regeneration of the donor remnant liver.MethodsBetween August 2008 and August 2009,28 LDLT were performed with 11 LDLT without MHV (group A) and 17 LDLT with MHV (group B).The donor operative time,intraoperative blood loss,postoperative hospital stay,bilirubin,INR,and ALT level were recorded in detail.We measured the volume of remnant liver by means of CT scan 2 weeks after operation and compare the degree of congestion and regeneration of the remnant liver between the two groups.ResultsThere were 10 cases in group B and 0 cases in group A suffering from congestion at segment Ⅳ,and the difference was significant(P =0.006).In group B,6 cases in type Ⅰ and 4 cases in type Ⅱ developed congestion at segment Ⅳ,and the difference was significant(P=0.035).Two weeks post operation,the volume of segment Ⅳ in group B was smaller than in group A(P=0.005).The regeneration rate of segment Ⅳ in group B was smaller than in group A (P =0.007),on the contrary,the regeneration rate of segment Ⅰ - Ⅲ in group B was larger than in group A( P =0.008 ).But the regeneration rate of remnant liver was the same in both groups (P =0.63 ).ConclusionsThe right lobe hemihepatectomy with MHV does not damage the early liver function of the donor significantly.The segment Ⅳ of the remnant liver suffered from congestion and impeded the regeneration,but was compensated by the regeneration of segments Ⅰ - Ⅲ.

Objective To investigate the experience of treating Budd-Chiari syndrome through orthotopic liver transplantation.Methods The clinical data of LTx performed on 9 patients with Budd-Chiari syndrome from December 2003 to April 2010 were retrospectively analyzed. We summarize the preoperative image and surgical experience,and observe the occurrence of postoperative complications and survival. Results Budd-Chiari syndrome was diagnosed in 9 patients by the preoperative abdominal CT enhancement and vascular reconstruction,and cavity venography was done to observe obstruction and sub-type of CAVA vein.All 9 patients were subjected to cadaveric liver transplantation.Eight cases accepted classic non bypass type,and one accepted living related right lobe liver transplantation. Postoperative triple immunosuppressive regimen included tacrolimus,mycophenolate mofetil,and hormone.The average follow-up periods for all these 9 patients were 32.8 months (13 to 61 months). One patient died from the tumor recurrence at 35th month after the operation.Two patients received re-transplantation for the lost of the graft.One recipient received the donor liver with medium steatosis,and the re-transplantation was performed on the12th day after the first transplantation due to the primary non function of the graft.The other one received the secondary liver transplantation at 6th month after the first transplantation due to the biliary complication and died from the liver tumor recurrence. Among all the 9 cases,seizure disorder (1 case),dysfunction of duodenal papillary muscle (1 case) and small-for-size syndrome (one case) occurred after the operation.Pulmonary infection occurred in 4 cases:3 cases due to the bacterial infection and 1 due to the fungal infection. Neither outflow obstruction nor the recurrence of the Budd-Chiari syndrome occurred in this study.The 1- and 2-year survival rate after the operation was both 100％,and 3-year survival rate post-transplantation was 88.9％ (8/9).Conclusion Liver transplantation can be the ideal treatment to the Budd-Chiari syndrome based on the definite clinical diagnosis,accurate imaging evaluation and eligible modus operandi.
