Objective To determine antiturbulent effect of the third-generation anti-HCV ELISA kit.Methods Anti-HCV ELISA kits from domestic and foreign manufacturer were used to detect the samles.Thost samples with positive results obtained using different anti-HCV ELISA kits from five manufacturers were further tested by HCV BLOT to determine which result would be true.Then RT-PCR would be done on the samples with anti-HCV “Indeterminate” by HCV BLOT.Results False positive rate of five kinds of anti-HCV ELISA kits on 268 selected weak positive samples were 0.37%～12.68%.The results from different anti-HCV ELISA kits showed markedly inconsistent.If any two kinds were combined to detect the samples,the false positive rates declined 0～2.2%(P

Objective To study ethanol-induced the neuroapoptosis of visual cortex in offspring mice. Methods Pregnant female mice were fed by intubating alcohol daily,beginning on E5(embryonic,E) and continuing through the pup's birth.The neuroapoptosis in P0,P7 and P14 visual cortex was visualized by Caspase-3 activity immunohistochemistry and Terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling(TUNEL) staining. Results Usually,the pup's birth days would delay one or two days after ethanol exposure.Moreover,ethanol induced reabsorption of fetus and malformations,such as microcephaly,anencephaly and myeloschisis with spinabifida and so on,were found in the study.Apoptosis index in ethanol treatment groups was obviously higher than that in control at either P0,P7 or P14(P

Objective:To explore the postoperative complications of different incisions of parotidectomy in benign parotid tumor and the impact on life quality.Methods:62 patients with benign parotid ttmor underwent improved parotidectomy in our hospital from January 2010 to January 2015 were selected and randomly divided into group A and group B.The patients in group A were using improved S incision,and the patients in group B were using postauricular concealing incision.Then the perioperative indexes,complications after surgery and the influences to life quality of 2 groups were observed and compared.Results:The surgery time,blood loss,postoperative suction drainage and hospital stays of 2 groups had no great differences (P＞0.05).The early and forward complication rate of group A was 29.03 ％ and 25.81％ respectively,of group B was 19.35 ％ and 12.90 ％ respectively.There were no differences between them (P＞0.05).The scores of pain and emotion after surgery of group A were getting better,and appearance,smell and chewing function was getting worse than before surgery with statistically significance (P＜0.05).The scores of pain and emotion after surgery of group B were getting better than before (P＜0.05).The scores of appearance and emotion of group A were worse than those of group B with statistically significance (P＜0.05).Conclusions:Using postauricular concealing incision can obtain good life quality and safety for the patients with benign parotid tumor,which is superior to improved S incision,worthy of clinical applications.

Aim To study ethanol-induced changes in the development and neuronal number of visual cortex in C57BL /6 mice. Methods Female mice were fed with ethanol during pregnancy . The neuron density (ND) and cortical thickness (CT) in visual cortex of off spring mice were measured at either P0, P7 and P14 with hematoxylin and eosin (H.E) and Nissl staining. Results Embryonic death and malformationswere found in the ethanol-treated groups. Malformations, such as microcephaly,anencephaly and myeloschisis with spinabifida, etc were found in late-term embryos. The malformation rate was 12%. Compared with control group, the development of visual cortex in ethanol-treated groups was delayed, and its lamination was in disorder. The neuron polarity was disturbed. Neuron loss was found after ethanol exposure. At various ages, the neuron density in ethanol-treated groups was lower than that in control group(P

Objective To study the inhibitory effects of dehydroepiandrosterone (DHEA) and its metabolites-dehydroepiandrosterone sulfate (DHEAs) on the proliferation of HepG2 and HT-29 and their mechanism.Methods HepG2 and HT-29 were incubated by DHEA or DHEAs with different concentrations (1,10,50,100 and 200 ?mol?L-1) for 8,24,48,72 h and routine culture was used as control.The inhibitory rate was detected by using MTT chromometry and BrdU assay respectively.The activities of 3-hydroxy-3-methylglutaryl coenzyme A reductase(HMGR),glucose -6-phosphate dehydrogenase (G6PD) and lactate dehydrogenase (LDH) were examined simultaneously.Results ①MTT chromometry:DHEA with different concentrations obviously inhibited the growth of HepG2 and HT-29 cells compared with control group(P0.05).②BrdU assay:the growth of cells were significantly inhibited by DHEA with concentrations of 50,100 and 200 ?mol?L-1,especially to HepG2 cells(P0.05).Conclusion DHEA has strong anti-proliferative effects on both HepG2 and HT-29 cell lines and inhibitory effects on the activities of G6PD or HMGR,however,DHEAs has no obvious effect.

Objective To explore the feasibility of fluorescence quantitative PCR(FQ-PCR)in prenatal diagnosis of the fetal RhD genotyping using free DNA from RhD-negative pregnant women.Methods The fetal RhD gene was amplified from 78 RhD-negative pregnant women with single fetus maternal plasma (gestation from 11 to 40 weeks).Rhe existence of fetal DNA was confirmed by amplification ofnine different polymorphic short tandem repeat loci(STR)and sex-determining region Y chromosome(SRY)gene.Exon5,7,10 and intron 4 were amplified by real-time polymerase chain reaction with TaqMan probe.The results of fetal RhD genotyping were evaluated retrospectively by the serologic analysis of infant cord blood.Results Among the 78 specimens,the SRY positive signals were detected from samples of 41 and were all identified male fetal through 8ex observation after newborn infants delivered from the women enrolled.The mean concentration of SRY gene reached(214.7±120.9)eopies/ml.RhD genotyping results of 70 cases were in complete concordance with the resets through serological detection of fetal cord blood after delivery.In addition,5 cases were false-positive.3 cages were considered inconclusive.The coincidence rate was 90%(70/78).From 5 false-positive cases,4 cases were identified as RhDel phenotype by detecting RHDl227A allele gene.The final accuracy rate of FQ-PCR was 95%(74/78)in the fetal RhD genotyping.Conclusion FQ-PCR analysis for noninvasive prenatal of fetal RhD genotyping could be useful in prevention and diagnosis of hemolytic disease of newborn.

Objective To study the expression of forkhead box 2(FOXC2)and delta-like liGand 4 (DLL4)in invasive ductal carcinoma(IDC)of breast and the clinical siGnificance. Methods The expression of FOXC2 and DLL4 in l22 cases of IDC(Grade Ⅰ33,Grade Ⅱ40,GradeⅢ 49)were observed by tissue chip and immunohistochemistry. The relationship of the expression with clinicopatholoGical characteristics and between FOXC2 and DLL4 were statistically analyzed. PCR experiment was performed in normal breast tissue,ductal carcinoma in situ(DCIS)IDC Grade Ⅰ,Grade Ⅱ and Grade Ⅲ(l0 cases respectively). Results The positive rate of FOXC2 and DLL4 in IDC was 77. 87% and 74. 59% respectively. A hiGher expression was observed in GradeⅢ than in GradeⅠand Ⅱ( P<0. 05 ). The expression of FOXC2 was related to the neGative expression of ER. The expression of DLL4 was related to the tumour size,clinical staGe and lymph node metastasis( P<0. 05). The RCR of FOXC2 and DLL4 were Gradually increased in normal breast tissue,DCIS,IDC GradeⅠ, Grade Ⅱ and Grade Ⅲ(P<0. 05). Moreover the expression of FOXC2 was related to the expression of DLL4(r=0. 233,P=0. 0l0). Conclusion FOXC2 and DLL4 miGht toGether have influence on the proGression and outcome of breast carcinoma,and could be important markers of proGnosis. DLL4 miGht be reGulated by variety of factors includinG FOXC2 at the same time.

Objective To explore the effects of hand-arm bimanual intensive training (HABIT) in group on functional independence and quality of life of children with hemiplegic cerebral palsy. Methods From November, 2015 to September, 2016, 20 children with hemiplegic cerebral palsy were randomly divided into control group (n=10) and experimental group (n=10). Both groups received routine occupational therapy, and the experimental group received HABIT in group one hour per day additionally, for eight weeks. They were assessed with the Carroll Upper Extremities Functional Test (UEFT), Functional Independence Measure Children's Edition (WeeFIM) and Chinese Version Pe-diatric Quality of Life Inventory (PedsQLTM) 3.0 Cerebral Palsy Module respectively before and after treatment. Results After treatment, the scores of UEFT, WeeFIM and the PedsQLTM3.0 improved in both groups (t>3.970, P<0.05), and were higher in the experimental group than in the control group (t>2.306, P<0.05). Conclusion HABIT in group could improve the fine function of upper extremity and hands coordina-tion of children with hemiplegic cerebral palsy, and enhance the functional independence and quality of life.
