Objective To investigate the clinical efficacy, the toxicity and side reactions of interventional chemoembolization with FOLFOX4 regimen through both hepatic artery and superior mesenteric artery, i.e. dual access technique, in treating primary hepatocellular carcinoma. Methods Between November 2010 and March 2013 at authors’ hospital, a total of 21 patients with advanced primary hepatocellular carcinoma (the study group) were treated with FOLFOX4 regimen by using dual access interventional technique. FOLFOX4 regimen included hepatic arterial infusion of 5-fluorouracil 400 mg/m2, hepatic arterial chemoembolization with iodipin and oxaliplatin 85 mg/m 2, intravenous administration of calcium folinate 200 mg/m2 IV on the first and second day, trans-superior mesenteric artery continuous infusion (lasting for 22 hours) of 5 -Fuorouracil 600 mg/m2 on the first and second day. During the same period other 21 patients with primary hepatocellular carcinoma were selected (used as the control group) to receive conventional hepatic arterial chemoembolization. In both groups, the treatment was repeated after 4-6 weeks. The therapeutic effect and the toxicity and side reactions were evaluated after the second treatment. Results The effective rate for the study group and the control group was 61.9% and 28.6% respectively, and the median survival time for the study group and the control group was 14.7 months and 9.4 months respectively. The differences in the effective rate and the median survival time between the two groups were statistically significant (P = 0.030 and P = 0.034). The occurrence of toxicity and side reactions, such as digestive tract reactions and the damage of liver function, in the study group were strikingly lower than those in the control group. Conclusion Through dual approach of hepatic artery and superior mesenteric artery catheterization, interventional chemoembolization with FOLFOX4 regimen is outstandingly effective for primary hepatocellular carcinoma, meanwhile, the side effects are very slight.

Objective To investigate the clinical symptoms and imaging features of Budd-Chiari syndrome with hepatic vein obstruction (HVBCS) and the reasons of mistreatment. Methods Thirteen patients with HVBCS were misdiagnosed and mistreated as inferior vena cava (IVC) obstruction,including 8 patients treated with stent implantation in IVC once and 5 patients with balloon dilatation. After analysis of the clinical symptoms,signs and imaging features; hepatic vein obstruction was further confirmed by digital subtraction angiography (DSA)in all patients. Results All patients had variable degrees of portal hypertension and no apparent symptoms of IVC obstruction. CT or / and MRI showed obvious caudate lobe enlargement and DSA showed IVC narrowing with external compression. All patients were undertaken hepatic vein angiography including 4 with PTV and 9 with hepatic vein stent implantation. All patients' clinical symptoms and signs completely disappeared or markedly improved after the procedure. Conclusion The stenosis of IVC in HVBCS,caused by compression compensatory hypertrophy of hepatic caudate lobe can be cured by hepatic vein angioplasty which is the most correct and effective method.

OBJECTIVE:To study the in vitro uptake of Resibufogenin(RBG)lactic acid glycolic acid copolymer-water solu-ble vitamin E (PLGA-TPGS) in human liver cancer HepG2 cells,mouse ascites-type lymphatic metastasis of tumor HCa-F cells, and the toxicity on HepG2 cells. METHODS:RCPTN loading RBG and coumarin-6(C6)were prepared. Fluorescent inverted mi-croscope was used to observe the in vitro uptake by RCPTN HepG2,HCa-F cells. It was divided into negative control group,blank PLGA-TPGS nanoparticles(EPTN)group,5-fluorouracil solution(FS)group,RBG solution(RS)group,RBG/PLGA nanoparti-cles(RPN)group and RPTN group. WST-1 was conducted to investigate the optical density at 450 nm wavelength of HepG2 cells after 24,48,72 h incubated by FS,RS,RPN and RPTN with different final concentrations (1.25,2.5,5,10,20 μg/mL);the cell viability (CV) and half inhibitory concentration (IC50) were calculated. RESULTS:RCPTN distributed around the nucleus of HepG2,HCa-F cells. CV was decreased by RBG concentration increased in RPN group and RPTN group,and decreased by time prolonged;compared with FS group,CV in RPTN group was decreased(P<0.05 or P<0.01). IC50 of HepG2 cells incubated by FS,RS,RPN and RPTN was decreased by time prolonged,ordered by RS>FS>RPN>RPTN;IC50 incubated by RPN and RPTN for 48,72 h was obviously less than that of FS and RS(P<0.05 or P<0.01). CONCLUSIONS:RPTN can deliver RBG in-to HepG2,HCa-F cells,showing inhibition effect on HepG2 cells which is stronger than RPN,RS and FS.

Objective To investigate the change of serum Nogo-A protein in patients with acute closed brain injury, and explore its relationship with the severity of neuronal damage and prognosis. Methods Thirty-one patients with acute closed brain injury were enrolled. Venous blood samples (2 mL) were obtained 1, 3 and 5 d after injury. Serum concentrations of Nogo-A protein were determined by ELISA. Patients were divided into mild (n =7), moderate (n = 10) and severe (n = 14) injury groups according to Glasgow coma score (GCS), and were divided into favorable prognosis (n = 23) and poor prognosis (n = 8) groups according to Glasgow outcome score (GOS). Another 20 healthy adults were served as controls. Results The mass concentrations of serum Nogo-A protein in mild, moderate and severe injury groups 1, 3, 5 d after injury were significantly higher than those in control group (P < 0.01), and the mass concentrations of serum Nogo-A protein in moderate and severe injury groups 1, 3, 5 d after injury were significantly higher than those in mild injury group (P <0.05, P <0.01). The mass concentrations of serum Nogo-A protein 1, 3, 5 d after injury were significantly higher in poor prognosis group than those in favourable prognosis group (P < 0.01). Conclusion Serum Nogo-A protein level significantly increases after brain injury, and is related to the degree of injury and prognosis.

Chinese journal of integrative medicine 2015;21(7):542-550
OBJECTIVETo evaluate the efficacy and safety of Ginkgo Biloba extract for patients with angina pectoris according to the available evidence.
METHODSElectronic databases were searched for all of the randomized controlled trials (RCTs) of angina pectoris treatments with Ginkgo Biloba extract, either alone or combined with routine Western medicine (RWM), and controlled by untreated, placebo, Chinese patent medicine, or RWM treatment. The RCTs were retrieved from the following electronic databases: PubMed/MEDLINE, ProQuest Health and Medical Complete, Springer, Elsevier, and ProQuest Dissertations and Theses, Wanfang Data, China National Knowledge Infrastructure (CNKI), VIP database, China Biology Medicine (CBM), Chinese Medical Citation Index (CMCI), from the earliest database records to December 2012. No language restriction was applied. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. RevMan 5.1.0 provided by Cochrane Collaboration The data were analysed by using.
RESULTSA total of 23 RCTs (involving 2,529 patients) were included and the methodological quality was evaluated as generally low. Ginkgo Biloba extract with RWM was more effective in angina relief and electrocardiogram improvement than RWM alone. Reported adverse events included epigastric discomfort, nausea, gastrointestinal reaction, and bitter taste.
CONCLUSIONSGinkgo Biloba extract may have beneficial effects on patients with angina pectoris, although the low quality of existing trials makes it difficult to draw a satisfactory conclusion. More rigorous, high quality clinical trials are needed to provide conclusive evidence.

0.05). Expression of MDR1 had a positive ~correlation with mutant p53 accumulation and HER2 expression(P0.05 ).In univariate analyses,TNM staging, axillary lymph node metastasis, mutant p53 accumulation, and HER2 over-expression were negatively correlated with DFS and OS, and MDR1 over-expression significantly reduced OS but not DFS. In multivariate analysis, axillary lymph node metastasis, over-expression of MDR1 and HER2 were independent risk factors for prognosis. Conclusions ~Induction of multidrug resistance and poor response to chemotherapy and endocrinotherapy may be the chief reasons for poor prognosis of breast cancer with mutant p53 accumulation, and HER2 and MDR1 over-expression. ~Determination of the above genes′expression in breast cancer tissue can be of use in deciding the degree of ~malignancy , metastasis phenotype and prognosis of brest cancer. Increasing anthracycline dose may increase the ~overall response rate to chemotherapy and improve prognosis in patients with mutant p53 accumulation, HER2 and MDR1 over-expression, especially HER2 over-expression.

The pathogenesis of HBsAg (+)/HBsAb (+) double positive hepatitis B virus infection was investigated by simulating HBsAg/HBsAb coexistence in vitro and establishing HBsAg/HBsAb double positive model in vivo. Eukaryotic expression plasmids PCI-SY, PCI-adw, PCI-adr, PCI-ayw, which expressed S gene product of different serotypes, were constructed and transfected into HepG2 cells. Recombinant proteins were purified from the transfected cells. At the same time, HBsAg mouse antiserum was obtained by immunizing mice with PCI-SY plasmid. HBsAg/HBsAb coexistence was simulated using these antigens and antiserum. Furthermore, the expression plasmids expressing different serotypes of S gene product including PCI-adw, PCI-adr, and PCI-ayw were injected into mice via tail vein. HBsAg and HBsAb in mice sera were tested at the first and 7th day respectively after antigen plasmids injection. Both in vitro simulation and in vivo animal models demonstrated that HBsAg antigen and HBsAb of the same serotypes could not coexist, but HBsAg antigen and HBsAb of different serotype could coexist. HBsAg/HBsAb double positive hepatitis B virus infection could be due to infection of viruses of different serotypes.
