A total of twenty eight HSV isolates from the patients were typed by using HSV typespecific monoclonal antibodies (McAb). Comparison of typing results with McAb in three Sero-lminunological methods with molecular hybridization indicated 100% concordance in the results. But the typing rates were quite different among the various methods (ELISA 64%, IFA and EIA 82%, Hybridization 100%). The results demonstrate that the molecular hybrydization with HSV type-specific probes was highly sensitive and specific, and the method of EIA with HSV type-specific McAb was accurate, cheap, rapid and practical.

Objective To investigate the effectiveness of donepezil in the treatment of early post-stroke aphasia (PSA).Methods PSA patients within one month after onset were randomly assigned into either a donepezil group or a control group.On the basis of conventional medication,the donepezil group was given hydrochloride donepezil 5 mg/d.The patients were followed-up after 4 week.The efficacy was evaluated by the Aphasia Battery of Chinese (ABC),the National Institute of Health Stroke Scale (NIHSS),the Stroke Aphasic Depression Questionnaire (SADQ),Chinese version,and the Treatment Emergent Symptom Scale (TESS) before and after treatment.Results A total of 48 PSA patients were enrolled in the study.Both the donepezil group and the control group had 24 patients and they all completed the study.There were no significant differences in age,years of education,NIHSS score,SADQ score,stroke duration,as well as the proportions of male,hypertension,diabetes,hyperlipidemia,heart disease,previous stroke or history of transient ischemic attack,smoking alcohol consumption,type of stroke,and lesion site (all P ＜ 0.01).There were significant differences in each language score before and after treatment both in the donepezil group and in the control group (all P ＜0.01).The difference values of listening comprehension (47.8 ± 24.7 vs.22.0 ± 15.4; t =4.342,P =0.000)and reading comprehension (20.5 ± 14.0 vs.8.1 ± 10.5; t =3.483,P ＜0.01) scores before and after treatment in the donepezil group were significantly higher than those in the control group,while there were no significant differences in the information quantity of speech,fluency,series language,repetition,naming,and reading scores (all P ＞0.05).As compared with the control group,there were significant differences in the difference values of the SADQ scores before and after treatment in the donepezil group (6.2 ±6.0 vs.2.5 ±3.0; t =2.717,P=0.009).No serious adverse reactions were observed in both groups.Conclusions On the basis of conventional stroke treatment,using hydrochloride donepezil in the early PSA patients has promotion effect on the improvement of listening comprehension and reading comprehension of language function.

Objective To observe activated cerebral areas during the task of writing in second language by early and late acquisition bilinguals and explore the neuropsychological mechanism. Methods Twelve subjects were divided into group of early acquisition high proficiency bilinguals(EAHP) and group of late acquisition high proficiency bilinguals(LAHP). Each subject carried out the task of pseudo-writing and English writing. After functional imaging,statistical parametric mapping was used to compare data of the two tasks through paired- t test in both two groups. A conjunction analysis was conducted between the two groups also. Areas where the metabolism of glucose changed were analyzed. Then, the corresponding images about activated cerebral regions were obtained.Results Cerebral areas where the metabolism of glucose increased in EAHP: bilateral middle frontal gyrus( Z=4.35/2. 01 ), bilateral cerebellum ( Z = 2.97/2.53 ) and left head of caudate nucleus ( Z = 3.07 ), etc. Cerebral areas where the metabolism of glucose increased in LAHP: right superior frontal gyrus(Z=4.06), right cerebellum( Z=4.63), left putamen(Z=2.70) ,etc. Cerebral areas where the metabolism of glucose increased in compared data of LAHP with data of EAHP: right frontal gyrus ( Z = 2.92 ), right temporal lobe( Z = 2.31 ), etc. Conclusion Extensive cerebral cortex and subcortical structures participate the process of writing in the second language. Age of bilingual acquisition is one of the factors affecting cerebral localization of writing in second language.

The subjects were treated for 6 courses with a one-month follow-up. The therapeutic efficacies were compared between the two groups.Result The total effective rates were respectively 94.3% and 80.0% in the treatment group and control group.Conclusion Zhuang’s medicated thread moxibustion plus acupoint thread embedding has significant advantage in improving the symptoms of allergic rhinitis.

Aim To investigate the effects of bone morphogenic protein(BMP)-7 on the expression of extracelluar matrix components(ColⅠand FN)in human renal proximal tubular cells(HK-2)induced by transforming growth factor-?1(TGF-?1),and to explore the inhibition of BMP-7 on renal interstitial fibrosis.Methods HK-2 cells were treated with TGF-?1,BMP-7,or a combination of both for 48 h.The expression of FN was assessed by indirect immunofluorescence.RT-PCR and Western blot were used to determine the mRNA and protein expression of FN and ColⅠ?1.Results Indirect immunofluorescence staining showed that FN staining in 3 ?g?L-1 TGF-?1 group was considerably stronger than that in control group.By an addition of 200 ?g?L-1 BMP-7,the expression of FN was significantly inhibited.RT-PCR and Western blot showed the mRNA and protein expression of FN and ColⅠ?1 were up-regulated by TGF-?1 after 48 hours significantly(P

Objective To analyze the relationship among the general self-efficacy,self-esteem and professional identification of nursing baccalaureate students and to provide some suggestions for educational practice. Methods A total of 403 nursing baccalaureate students in traditional Chinese medicine colleges were recruited. They were investigated with general self-efficacy scale (GSES), Rosenberg self-esteem scale(SES)and questionnaire for baccalaureate nursing students (QBNS). The relationship among general self-efficacy,self-esteem and professional identification was analyzed by multiple stepwise regression analysis. Results The mean score of general self-efficacy was 23.81± 5.27. There were significant differences in the score of general self-efficacy among different grades and enrollment methods (P<0.01). The nursing students,general self-efficacy was positively correlated with self-esteem,professional identification,professional emotion and professional skills(r=0.11-0.50, P<0.05). Conclusions Nursing educator should pay attention to the cultivation of self-esteem and professional identity in the training of nursing student in order to improve the self-efficacy of nursing students.

A truncated mutant of the Open Reading Frame 2 (ORF2, aa384-606) was amplified from cDNA of genotype IV hepatitis E virus (HEV) by polymerase chain reaction (PCR), subcloned to expression plasmid pTO-T7, and expressed in Escherichia coli. SDS-PAGE and Western blotting were used to detect and identify the recombinant protein, namely rP24. After washing of inclusion bodies, dissolving in denaturing agents, refoldeding by dialysis, ion exchange chromatography and gel chromatography, dynamic light scatter was used to study the hydrated radius of rP24. Western blotting was applied to detect the immunoreactivity of rP24, and mouse immunity test and indirect enzyme linked immunosorbent assay (ELISA) were applied to evaluate the immunogenicity and the detection rate of HEV positive and negative serum. SDS-PAGE and Western blotting show that rP24 was highly expressed in the form of inclusion bodies after induction, and had strong immunoreactivity to monoclonal antibody (McAb) 15B2. After a multi-step purification of rP24, Western blotting indicated that the purified rP24 also had strong immunoreactivity to neutralizing McAb 8C11 and HEV positive serum, suggesting that rP24 simulated the nature structure of HEV capsid protein. Dynamic light scatter demonstrated that the average hydration radius of purified rP24 was 7.48 nm. The mouse immunity test showed that the purified rP24 also had good immunogenicity, and the period of serum antibodies converted from negative to positive was very short, but the antibodies maintained more than 20 weeks. Indirect ELISA tests showed that the detection rate of was the same as anti-HEV-IgG diagnostic kit (Wan Tai corporation). Taken together, the rP24 simulated the neutralizing epitopes of natural HEV, and had strong immunoreactivity and immunogenicity. It provided a basis for the further investigation of the difference of infection mechanism between genotype I and genotype IV HEV.
