Objective: To investigate the protective influence and mechanism of Yishen Huayu Formula on the expression of connective tissue growth factor (CTGF)in the rat with renal interstitial fibrosis. Methods: 150 rats were randomly divided into sham-opration group, model group, Lotensin treatment group, Yishen Huayu high low dose treatment groups. The rat models with renal interstitial fibrosis were induced by unilateral ureteral obstruction. The expressions of CTGF in the kidneys were observed on 3rd, 7th, 14th, 21st, 28th day. The alterations of renal the expressions of CTGF in the kidneys were observed with the ?-actin as intrinsic control. Results: Compared with the control group,the expression of CTGF increased signifi cantly in model group(P

Objective To analyze the risk factors of hepatocellular carcinoma (HCC) recurrence after liver transplantation based on 18F-FDG PET/CT.Method We respectively analyzed 54 cases of HCC patients who accepted liver transplantation from 2008 September to 2012 November.The clinicopathological features of 54 patients were analyzed by univariate and multivariate analysis to determine the risk factors of HCC recurrence after liver transplantation.The ROC curve was drawn to determine the optimal cutoff value of T/B that affects HCC recurrence after liver transplantation.Result The total incidence of HCC recurrence was 48.1% (26/54); the disease-free survival (DFS) rate of 0.5 year,1 year and 2 years after transplantation in 54 patients was 92.6%,66.7%,52.2%,49.1 % and 49.1% respectively.The univariate analysis results showed that there were 5 variables to affect HCC recurrence,namely PET imaging,tumor size,tumor number,preoperative AFP level,and tumor degree.On ROC curve analysis,the optimal cutoff value for T/B was 1.69.The multivariate analysis concluded that T/B,and preoperative AFP level were independent factors.Conclusion T/B >1.69 and preoperative AFP level >400 μg/L are important biological factors of HCC recurrence after liver transplantation.

Objective To investigate the diagnostic efficacy of 13N-NH3 and 18F-FDG PET/CT in the evaluation of untreated gliomas.Methods A total of 45 consecutive patients (29 males,16 females;age range 14-75 years,average age (47.47± 15.64) years) with final diagnosis of glioma from August 2009 to May 2012 were retrospectively analyzed.PET/CT imaging was performed with both 18F-FDG and 13N-NH3.Imaging results were analyzed by tumor-to-gray matter (T/G) ratios.ROC curve analysis was conducted to determine the optimal T/G cutoff values between low-grade and high-grade gliomas.One-way analysis of variance was applied to assess the differential efficacy of the two tracers in different grade of glioma.Results Forty-eight separate lesions were identified (WHO grade Ⅱ,n=16;grade Ⅲ,n=12;and grade Ⅳ,n=20).The sensitivities of 13N-NH3 PET/CT and 18F-FDG PET/CT on predicting high-grade gliomas were 91%(29/32) and 66% (21/32),respectively.The optimal T/G cutoff values for 18F-FDG and 13N-NH3 were 0.64 and 0.86 with the AUC of 0.910 and 0.943,respectively.The sensitivity and positive predictive value of predicting high-grade gliomas with optimal cutoff values were 84% (27/32) and 93% (27/29)for 18F-FDG PET/CT,those for 13N-NH3 PET/CT were 94% (30/32) and 94% (30/32),respectively.Conclusion 13N-NH3 PET/CT is superior to 18F-FDG PET/CT not only in separating low-grade gliomas from high-grade ones,but also in the detection of high-grade gliomas for better tumor to normal gray matter contrast.

Objective To explore the value of 18F-FDG PET/CT in predicting tumor recurrence for hepatocellular carcinoma (HCC) after liver transplantation (LT).Method We respectively analyzed 52 patients with HCC who underwent the 18F-FDG PET/CT examination before LT.In terms of tumor recurrence,all patients were divided into recurrence group and non-recurrence group.According to the degree of 18F-FDG uptake,all patients were divided into PET(-) group and PET (+) group.The SUVmax of primary tumor/the SUVmax of normal-liver background (T/B) was calculated by 18F FDG PET/CT.All patients were then divided into T/B≤1.15 group and T/B>1.15 group.Result During the follow-up period,25 out of 52 patients (48.1%) developed posttransplant HCC recurrence and 27 (51.9%) had no recurrence.T/B of patients with recurrence (2.51 ± 0.95) was significantly higher than that of patients with non-recurrence (1.37 ± 0.46),t =4.12,P<0.001.The disease-free survival rate of 0.5 year,1 year,2 years and 3 years after LT in PET(-) group and PET(+) group was 100.0%,92.3%,92.3% and 92.3%,and 89.7%,59.0%,43.6% and 35.7% respectively.Log-rank test revealed that disease-free survival rate in PET(-) group was significantly higher than that in PET(+) group,x2 =17.8,P=0.003.The disease-free survival rate of 0.5 year,1 year,2 years and 3 years after LT in T/B≤1.15 group and T/B>1.15 group was 100.0%,92.3%,92.3% and 92.3%,and 89.5%,59.7%,42.1% and 33.7% respectively.Log-rank test showed that disease-free survival rate of T/B≤1.15 group was significantly higher than that of T/B>1.15 group,x2 =10.24,P =0.001.Conclusion 18F-FDG PET/CT can predict HCC recurrence after LT.PET(-)and T/B≤1.15 of the 18F-FDG PET/CT in patients with HCC after LT were associated with a good prognosis,and PET(+) and T/B>1.15 of the 18F-FDG PET/CT in patients with HCC after LT with a poor prognosis.

Eleven env mutants were designed and generated by site-directed mutagenesis of the regions around Nab epitopes and deletions of variable regions in env.The immunogenicities of the generated mutants were evaluated using single-cycle infection neutralization assays with two pseudoviruses and IFN-γELISPOT.Overall,five mutants(dWt,M2,M5-2,M5-1 and dM7)induced highed neutralization activities for both pseudoviruses than plasmid Wt,while only two of the mutants(dWt and M5-2)showed significant differences(P<0.05).Two mutants(M2 and dM2)induced more Env-specific T cells than plasmid Wt.Statistically however,significance was only reached for mutant M2.Thus,properly modified HIV-1 Env may have the potential to induce potent cellular and humoral immune responses.

Background Idiopathic orbital inflammatory pseudotumor (IOIP) is a commom orbital disease,with serious eye symptoms and replase tendency,and its pathogenesis is still unclear.Nuclear factor-κB (NF-κB)-related proteins participate in many important pathophysiological process,however,whether NF-κB plays a role in the IOIP process is worthy of attention.Objective This study was to explore the roles of NF-κB pathway in IOIP pathogenesis.Methods Twenty-four IOIP specimens were collected during surgery in Beijing Tongren Hospital from September 2010 to May 2016.The histopathological characteristics of IOIP were examined by hematoxylin and eosin staining.The expression and location of NF-κB/p65,p-p65,p50 and inhibitor of κB (IκB-ot) were detected by immunohistochemistry and verified by immunocytochemistry and Western blot assay.Results The histopathological features of IOIP were numerous small lymphocyte infiltraion and fibrous tissue proliferation,and a lot of epithelioid cells were seen in lacrimal gland-involved specimens.NF-κB/p65 was positively expressed in the cytoplasm of all 24 specimens and the nucleus in 15 specimens with the expressing rate of 62.5%.p50 was expressed in the cytoplasm in 22 specimens with the expressing rate of 91.7% and in the nucleus in 17 specimens with the expressing rate of 70.8%.The positive expression of p-p65 was found in 22 specimens with the expressing rate of 91.7%,and IκB-α was expressed in the cytoplasm of 11 specimens with the expressing rate of 45.8%.These results were confirmed by immunocytochemistry and Western blot assay.Conclusions NF-κB pathway is activiated during IOIP process,and NF-κB pathway may be involved in the pathogenesis of IOIP.
