Objective To observe the effects of methylene blue photochemical(MB-P) inactivation of human cytomegalovirus in blood products.Methods Plasma and red blood cell suspensions containing 10% HCMV and 5?mol/L MB were illuminated by fluorescent light of 38000 Lux for 1 hour, HCMV was used as model viruses for validation of virus inactivation.Results The 50% tissue culture infective dose (TCID_ 50 ) contained in plasma and red blood cell suspensions decreased by 4~6 times.Conclusion MB-P treatment is effective in inactivating the infectivity of HCMV in plasma and red blood cell suspension.

ObjectiveTo evaluate the effect and safety of recombinant human erythropoietin (rhEPO) in treatment of lung cancer chemotherapy-related anemia.MethodsNinety-eight lung cancer chemotherapy-related anemia patients were divided into treatment group and control group with 49 cases each by random digits table method.The patients in treatment group were given rhEPO and chalybeate.The patients in control group were merely given chalybeate.The hemoglobin (Hb),hematocrit,allogeneic blood transfusion rate and quality of life between two groups were observed and compared.ResultsThree cases were rejected in treatment group,and 3 cases with anergy and dizzy and 2 cases with local injection site pain and sclerosis recovered spontaneously.Hb and hematocrit showed downward trend after treatment in control group,but there was no significant differences (P ＞ 0.05).Hb and hematocfit had upgrade trend after treatment in treatment group,and there were significant differences between after 4 - 8 months treatment and before treatment (P ＜ 0.05 ).The allogeneic blood transfusion rate was 24.5％ (12/49) in control group and 6.5％ (3/46) in treatment group,and there was significant difference between two groups (P ＜ 0.05 ).The quality of life in treatment group was increased compared with that in control group.There were significant differences in the effective rate after 4 or 8 weeks treatment between two groups [52.2％(24/46) vs.6.1％(3/49) and 95.7％ (44/46) vs.20.4％ ( 10/49 )].ConclusionsrhEPO is effective and safe in treatment of lung cancer chemotherapy-related anemia.rhEPO has little adverse reaction and can improve the quality of life.

In order to investigate the roles of MTA2 in the pathogenesis of ovarian epithelial cancer, the expression of MTA2 in 4 ovarian cell lines were detected by semi-quantitative RT-PCR and Western-blot assays. MTA2 expression in normal, borderline, benign and malignant epithelial ovarian tissues was immunohistochemically examined. The expression of MTA2 mRNA and protein was detected in all of 4 cell lines of ovarian epithelial cancer. The expression of MTA2 mRNA and protein was higher in strong migration cell lines than in weak migration ones. In borderline and malignant ovarian tissues tested, MTA2 staining was dramatically stronger than in normal and benign tissues (P < 0.01). The expression levels in malignant ovarian tissues were significantly higher than that in borderline epithelial ovarian tissues (P < 0.01). The expression of MTA2 was correlated with clinical stage, histopathological grade and lymph node metastasis. It was concluded that the high expression of MTA2 was associated with more aggressive behaviors of epithelial ovarian cancer. MTA2 provides a novel indicator of ovarian cancer.

Guanylate binding protein-1(GBP-1) is an interferon-induced protein. To observe its antiviral effect against Hepatitis B virus (HBV) and Coxsackie virus B3 (CVB3), we constructed an eukaryotic expression vector of human GBP-1(hGBP-1). Full-length encoding sequence of hGBP-1 was amplified by long chain RT-PCR and inserted into a pCR2.1 vector, then subcloned into a pCDNA3.1(-) vector. Recombinant hGBP-1 plasmids and pHBV1.3 carrying 1.3-fold genome of HBV were contransfected into HepG2 cells, and inhibition effect of hGBP-1 against HBV replication was observed. Hela cells transfected with recombinant hGBP-1 plasmids were challenged with CVB3, and viral yield in cultures were detected. The results indicated that recombinant eukaryotic expression plasmid of hGBP-1 was constructed successfully and the hGBP-1 gene carried in this plasmid could be efficiently expressed in HepG2 cells and Hela cells. hGBP-1 inhibit CVB3 but not HBV replication in vitro. These results demonstrate that hGBP-1 mediates an antiviral effect against CVB3 but not HBV and perhaps plays an important role in the interferon-mediated antiviral response against CVB3.

To establish a replication cellular model of hepatitis B virus (HBV) and determine its application in antiviral drug evaluation,we constructed an expression plasmid which contained 1.3 copies of the HBV genome,and measured the level of viral replication after transient transfection in Huh7 cells.We then observed the effect of antiviral drug administration.1.3 fold of the HBV(ayw) gene fragment was cloned into pCR2.1 by PCR and restriction endonuclease digestion.The recombinant plasmid was trans ient transfected into Huh7 cells,HBsAg,HBeAg and HBV DNA in supernatant of Huh7 cells were measured by ELISA and real-time PCR respectively; intracellular HBV replicative intermediates and intracellular HBV transcripts were detected by Southern blot and Northern blot respectively.The antiviral effect of adefovir,a novel anti-HBV nucleotide analogue,was evaluated in this cellular model system.The results indicated that a recombinant plasmid of HBV replicon was constructed successfully; the HBV genome carried in plasmid pHBV1.3 could efficiently replicate and be expressed in Huh 7 cells,adefovir could inhibit HBV replication in this cellular model,and the inhibition was dosage-dependent.The conclusion is HBV replicon,which can initiate viral replication efficiently in hepatoma cells,may be a useful tool in the study of HBV replication and antiviral drug.

Objective To evaluate the clinical effect of reversed nasolabial flap pedicled with superior labial artery for the recon-struction of nasal and infraorbital defects .Methods From September 2006 to May 2013 ,13 cases with large nasal and infraorbital defects were reconstructed by the reversed nasolabial flap pedicled with superior labial artery .In all patients these defects were re-sulted by the excision of carcinomas .The disease course ranged from 2 months to 28 years .The size of nasal and infraorbital defects was from 2 .0 cm × 1 .2 cm to 4 .0 cm × 3 .6 cm .All defects were restored by the reversed nasolabial flap pedicled with superior labial artery in 10 cases and by the island flap in 3 cases .The size of flap was similar to that of defects .The donor areas were sutured di-rectly .Results All flaps were completely survived .The incision at the donor and accepted sites healed in the first stage .In 4 pa-tients flap revision was performed after 6-12 months because of mild swelling at the pedicles of skin flaps .Patients were followed up for 4-60 months (the mean was 28 .4 months) .All patients were satisfied with the nasal ventilatory function and appearance , flap texture and color .No obvious scars were found at donor sites .Conclusion Reversed nasolabial flap pedicled with superior labial artery is a better choice to repair the nasal and infraorbital defect after excision of carcinomas .

Mild cognitive impairment caused by craniocerebral trauma is the key points and difficulties in judicial authentication. This article has comparative analysis of each mode of event-related potential (classical Oddball, Eriksen flanker task and so on), which can provide a more objective method for such craniocerebral trauma cases in clinical forensic judicial authentication.
