OBJECTlVE To study the anti-HBV activity of prepared recombinant human serum aIbu-min-interferon α-2b fusion protein(HSA-IFNα-2b) in vitro. METHODS HepG2 ceIIs were infected with recombinant adenovirus with green fIuorescence protein and 1.6-foId HBV DNA(AdGFP-HBV). The ex-pression of HBV antigens,HBsAg and HBeAg in cuIture medium was detected by ELISA assay. The tox-icity of HSA-IFNα-2b on HepG2 ceIIs was evaIuated by mTT assay.The reIative expression of HBV RNA in ceIIs and the absoIute quantity of HBV DNA in cuIture supernatant were determined by quantitative PCR assay. The activity of HBV enhancer Ⅰ was detected by DuaI-Reporter gene assay. RESULTS HBV couId repIicate and express in HepG2 ceIIs after infection with AdGFP-HBV. The expression of HBsAg and HBeAg in cuIture serum of HepG2 ceIIs infected with AdGFP-HBV decreased by 51.32%(P﹤0.01)and 50.26%(P﹤0.01),respectiveIy,when HSA-IFNα-2b 500 kU·L-1 was added. The same concentration of HSA-IFNα-2b didn't inhibit the proIiferation of HepG2 ceIIs,but inhibited HBsAg in a concentration-dependent manner. The regression formuIa between HBsAg inhibitory rate(Y)and con-centration of HSA-IFNα-2b(X)was Y=21.11 IgX+11.91(r 2 = 0.954),IC50 = 63.76 kU·L-1 . HBV RNA in ceIIs and HBV DNA in the cuIture serum decreased by 52.83%(P﹤0.01)and 53.07%(P﹤0.01), respectiveIy,when HSA-IFNα-2b 500 kU·L-1 was added. The activity of enhancer Ⅰ decreased by 40.04%(P﹤0.01)when HSA-IFNα-2b 500 kU·L-1 was added. CONCLUSlON The ceII modeI of HBV repIication for evaIuating anti-HBV agents is successfuIIy estabIished. HSA-IFNα-2b exhibits noticeabIe anti-HBV effect invitro.

Objective To investigate the effect of CT perfusion (CTP) imaging guidance in the treatment of acute cere?bral infarction. Methods Patients (n=200) with acute cerebral infarction who visited our clinic within 6 hours underwent CTP examination and were divided into two groups:penumbra group and non-penumbra group according to their CTP imag?ing (presence of penumbra or not). Recombinant tissue plasminogen activator (rt- PA) was administrated for intravenous thrombolysis in both groups. NIHSS (The NIH Stroke Scale), BI (Barthel Index), mRS (modified Rankin Scores) and hemor?rhagic transformation events of two groups were determined before and after thrombolysis to evaluate its effect and prognosis in these two group. Results Compared with non penumbra group, NIHSS was reduced in penumbra group from 7 days after rt-PA (6.67±3.46 vs 4.76±2.04), and this decrease became obvious at 4 weeks after rt-PA (6.67±3.46 vs 3.68±1.93). Effi?ciency rate at 4 week (60.3%) and good prognosis rate at 3 months(71.7%)were both significantly improved in penumbra group than those in non penumbra group(34.7%,56.8%). Conclusion rt-PA under CTP guidance is effective and safe in the treatment of acute cerebral infarction. The thrombolytic therapy window can be enlarged according to the presence of pen?umbra or not and the bleeding conversion rate remains at low level.

Objective To evaluate the expressions of CD68 and alpha/beta hydrolase domain-containing protein 5 (ABHD5) in gastric carcinoma and their interrelation,and the relationship with the clinicopathological features of gastric carcinoma.Methods The immunohistochemistry staining was used to determine the expressions of CD68 and ABHD5 in 60 cases of gastric carcinoma and 30 cases of adjacent normal tissues.The relationships between CD68,ABHD5 and clinicopathological features of gastric carcinoma,and the correlation of them were analyzed.Results The expressions of CD68 and ABHD5 in gastric carcinoma were significantly higher than those in adjacent normal tissues,and the positive expression rates were 65.00％ vs.26.67％(x2 =11.779,P =0.001) and 60.00％ vs.30.00％ (x2 =7.200,P =0.007) respectively,with significant differences.The expression of CD68 was related to TNM stage (x2 =7.959,P =0.005),lymph node metastasis (x2 =6.901,P =0.009) and serosal invasion (x2 =5.833,P =0.016),but it was not associated with pathological grade (x2 =0.028,P =0.866),gender (x2 =0.533,P =0.465) and age (x2 =0.060,P =0.807).The expression of ABHD5 was related to pathological grade (x2 =4.318,P =0.038),TNM stage (/x2 =4.051,P =0.044) and serosal invasion (x2 =5.275,P =0.022),but it was not associated with lymph node metastasis (x2 =0.545,P =0.460),gender (x2 =0.191,P =0.662) and age (x2 =1.358,P =0.244).Contingency correlation analysis showed that there was positive correlation between CD68 and ABHD5 in gastric cancer (c =0.328,P =0.010).Conclusion The expressions of CD68 and ABHD5 in gastric carcinoma are higher than those in adjacent normal tissues,which are correlated with the different clinicopathological features of gastric carcinoma.The expression of CD68 is positively correlated with the expression of ABHD5.The combined detection of CD68 and ABHD5 expressions in gastric carcinoma is helpful to evaluate the invasion,metastasis and prognosis of gastric carcinoma.
