To explore the feasibility of stable expression of Hantavirus H8205 strain G1 segment and human IL-2 fusion gene in Vero cells, and to examine the immune protection effects on mice vaccinated with this recombinant eukaryotic expression vector containing Hantavirus G1 gene and IL-2 gene. With the help of lipofectamine, the Vero cells were transfected with pcDNA3.1/HisB-IL-2-G1 and the positive cells were selected by G418. IFAT and SDS-PAGE electrophoresis were used to determine the stable transfection and expression of recombinant protein. Each mouse was inoculated with plasmids intramuscularly (i.m.) three times, 2 boosts were given at 2-week intervals, serum anti-hantavirus antibodies were detected by ELISA and neutralizing antibodies (NAb) were detected by Plaque Reduction Neutralization Test. The fusion protein expressed in Vero cells was 78 kD, corresponding to the estimated molecular size. The neutralizing antibody titers of mice with pcDNA3.1/HisB-IL-2-G1 were 1:20-1:80. IL-2/G1 fusion gene could be transferred in Vero cells and stably express the fusion protein. Specific humeral immune responses in mice can be induced with the recombinant eukaryotic expression vector containing the fusion gene, which lays the foundation for further development of therapeutic HTNV vaccine.

Objective To observe the effects of inhalation salbutamol combined with psychological intervention on the treatment of patients with severe asthma, and evaluate its clinical curative effect. Methods 162 cases with severe asthma were selected from February 2014 to February 2017 in hospital of traditional Chinese medicine in Zhoushan as the research object, which were randomly divided into the control group and the study group with 81 cases in each group. All patients were given nebulized salbutamol, the control group in the perioperative were given routine nursing intervention, at this basis, the study group were given targeted psychological nursing. The effect in the two groups was compared. Results The total effective rate in the study group was 91.36％ (74/81) was significantly better than that in the control group 76.54％ (72/81), the difference was statistically significant (P<0.05). After treatment, cough, shortness of breath, wheezing, chest tightness, lung wheezing were improved significantly , and all the symptoms in the study group was obviously better than those in the control group (P<0.05). Conclusion Aerosol inhalation of salbutamol combined with psychological intervention on the treatment of severe asthma patients has significant curative effect, which can significantly improve the clinical treatment effect, improve the clinical symptoms in a timely manner, and has the value of application and promotion.

Objective To develop a software through which transfusion labels can be created and printed automatically based on No.1 Military Medical Project,in order to resolve the problems of time-and-labor-consuming and errors due to transcription. Methods Based on No.1 Military Medical Project,the software of creating and printing transfusion labels was developed using PB computer programming language. Results The software can effectively avoid the errors due to copying transfusion labels by hand and save much time and effort. It optimizes nurses' working procedure. Conclusion The software is very practical for all the hospitals using the No.1 Military Medical Project.

Objective To investigate the quality of life and its influencing factors in hver transplantation recipients in order to supply scientific reference for improving their life quality.Methods 33 patients with terminal liver diseases waiting for liver transplantation(the pre-operation group)and 102 patients 2 weeks after liver transplantation and outpatients for follow-up visits(the post-operation group)were conducted with SF-36,self-rating anxiety scale,self-rating depression scale,and social support questionnaire.Results Except for the scores of physiological function,emotional role,social function in SF-36.differences of scores of other factors were evident between the preand post-operation groups.Life quality of patients over 1 year after operation was better than those within 1 year. The influencing factors of QOL were subjective support and anxiety.Conclusions After liver transplantation,the patients' QOL evidently improves.Life quality of patients over 1 year after operation was better than those within 1 year.Patients' QOL is positively related to subjective support,negatively related to anxiety.

Objective This study was to investigate the association of certain single nucleotide polymorphisms (SNPs) of the ER with genetic susceptibility to ISS .Methods Genomic DNA was extracted from peripheral blood of children with ISS (n=355) and of normal growth and development individuals as controls from Jiangxi province (n=345) .The association between the ER gene polymorphisms with the height-related clinical traits was analysed .Results The allele T of rs6557177 is significantly lower in the ISS group than in the control group(P=0 .021 ,OR=0 .624) .The clinical indexes of two kinds of different genotypes were analyzed and compared ,there was no statistical difference(P>0 .05) .Conclusion The allele T of rs6557177 of ER gene is a protection factor of ISS .C gene and T gene grouping clinical parameters (hight ,weight ,IGF-1 ,IGFBP3 ,E2 and BMI) were analyzed and found no statistically significant difference .

Objective To investigate the relationship of external hydrocephl(EH) with brain-injure in the neonate.Methods By performing on the patients with brain-injure with CT and making the clinical study,the change of brain following injure and its relationship with EH were analyzed.Results Hypoxic-ischemic encephalopathy(HIE) were 36 cases,EH were 19 in the cases,6 get the cerebrospinal symptom;SAH were 22 cases,EH were 15 in the cases,3 get the cerebrospinal symptom;Intracranial hemorrhage were 8 cases,EH were 3 in the cases,3 got the cerebrospinal symptom.Conclusion All the kinds of brain-injure can get EH and the rate of EH with any brain-injure is no different.But the outcome is significantly different.
