Objective To analyze the effect of prognosis of psychological counseling combined with early double anti antiplatelet on the treatment of acute cerebral infarction.Methods 76 patients with acute cerebral infarction who were admitted to our hospital from February 2014 to March 2016 were numbered according to their admission order.The patients with even numbers were in the observation group and with the odds number in the control group, 38 cases in each group.The control group were given aspirin and clopidogrel in the early stage, and the observation group were given psychological guidance on the basis of the control group.The prognosis in the two groups was recorded and analyzed.Results The neurological deficit score (NIHSS) and simple mental state score (MMSE) in the observation group (9.16±0.73)points, (25.42±2.00)points were significantly higher in the observation group than those in the control group (12.59±1.05)points, (20.73±2.16)points.And the differences were significant (P<0.05).The level of dailyliving activity index (Barthel) and Hamilton depression (HAMD) in the observation groupwere (80.86±3.29)points, (13.70±1.53)points, respectively, which were better than those in the control group (71.53±3.75)points, (18.53±1.99)points, and the differences were significant (P<0.05).The total adverse reaction rate in the treatment group was 18.42%, slightly higher than 14.29% in the control group, but the difference was not statistically significant.Conclusion Psychological counseling combined with early double antiplatelet intervention has positive effect on the prognosis in the patients with acute cerebral infarction.

Objective To construct the eukaryotic expression vector with the mutant of hypoxia inducible factor 1α (HIF-1α) that could over express nonhypoxic dependent HIF-1α and investigate its expression in eukaryotic cells PC12. Methods The coding sequence of HIF-1α was amplified from total RNA from the injured spinal cord of rats by means of RT-PCR. Then, overlapping extension PCR was employed to obtain one complete sequence encoding HIF-1α mutant without oxygen-sensitive degradation domain (ODD). By using gene recombination technique, the gene HIF-1α△ODD was inserted into eukaryotic expression vector _pEGFPC1 that contained a reporter gene of enhanced green fluorescent protein. The recombinant plasmid was successfully constructed and transfected into the neural cell line PC12. The expression of HIF-1α△ODD was analyzed by fluorescent observation and Western blot. Results A 2kb gene fragment encoding H1F-1α△ODD was successfully obtained by overlapping extension PCR. On this basis, the recombinant plasmid _pEGFPC1-HIF-1 α△ODD was constructed and testified with restriction enzyme digestion and DNA sequencing. After this recombinant plasmid was transfected into the neural cell line PCI2, both fluorescent observation and Western blot demonstrated that HIF-1α△ODD was over expressed under nonhypoxia conditions. Conclusion The eukaryotic expression vector _pEGFPC1-HIF-1α△ODD is successfully constructed and HIF-1α△ODD over expresses in transfected PCI2 cell lines.

BACKGROUND: The population of male and female adolescents in China accounts for 1/5. Adolescents have much psychological bewilderment,troublesome and even diseases on sexual issues.OBJECTIVE: To investigate the development status quo and the regulation of adolescents' sexual physiology, sexual psychology, sexual knowledge and sexual education.DESIGN: A cross-sectional survey by employing students of junior high school as subjects.SETTING: A clinic for adolescent of a tertiary hospital.PARTICIPANTS: Totally 960 students aged between 14 and 19 years old of three junior high schools in Dalian city were selected as subjects between November and December of 2001.METHODS: Self-complied questionnaire was used in the survey based on the sexual psychological education situation scale for junior and senior high school students. Classes were randomly selected for anonymous survey based on voluntary principle.Answers to sex-related questions and differences between male and female students.RESULTS: The average age of menarche in female students was 12.96years old and the average age of first emission in male students was 13.89years old, which were consistent with the results of similar national researches. The incidence and frequency of masturbation and sexual impulse was significantly higher in males than females. There were significant differences in sexual concept and the understanding of sexual knowledge between males and females. The desire to affiliate with the opposite sex was far more than the real occurrence.CONCLUSION: The understanding of sexual knowledge in adolescent is not satisfied. Students are also not satisfied with the sexual education provided by their schools. Hence, school sexual education for adolescents should be enhanced with the involvement of community.

Objective To investigate the coping strategies on college students facing infectious disease. Methods Interview,question-naires and Principal component analysis were used to explore the coping strategies of college students on infectious diseases. Results Col-lege students' coping strategies to infectious diseases involving seeking social support and active problem solving two principal components, in-volving 19 aspects. Conclusion As for colleges,a support platform should be built and the ability to actively solve problems urged to be strengthened for students. Among the coping strategies of College students’ toward to the infectious diseases,students choose to seek social support more than to solve the problem initiatively,indicating that gender differences and the environment may be related. The results provide a theoretical reference to public health and health education.

Objective To investigate the therapeutic efficacy of acupuncture plus Bobath therapy in treating motor dysfunction of the core muscles in patients with hemiplegia after cerebral stroke.Method Totally 144 patients with post-stroke hemiplegia were divided into a control group, treatment group 1 and treatment group 2. The treatment group 1 was intervened by Bobath therapy, while the treatment group 2 was by abdominal acupuncture and scalp acupuncture in association with Bobath therapy. The recruited patients were examined for the manual muscle strength rating of the abdominal core muscles, Berg Balance Scale (BBS) score, and Barthel Index (BI) score on the day of admission, the 30th day and 60th day after admission.Result There were no significant inter-group differences in comparing the core muscle strength, BBS, and the Activities of Daily Living (ADL) on the day of admission (P>0.05). The core muscle strength, BBS, and ADL were significantly increased on the 30th and 60th day after admission in the three groups (P<0.05), and the scores in treatment group 2 were significantly higher than that in the control group and treatment group 1 (P<0.05).Conclusion Acupuncture plus Bobath therapy can significantly improve the motor dysfunction of the core muscles in patients with hemiplegia after cerebral stroke.

Objective To investigate the expression of RGC32 gene in pulmonary adenocarcinoma tissue and to explore the influence on proliferation and apoptosis of A549 cells.Methods Real-time PCR was applied to detect the expression of RGC32 gene in 36 cases of pulmonary adenocarcinoma and pericancerous tissues.RNA interference was used to inhibit the expression of RGC32 gene.After RNA interference,the expression of RGC32 gene was detected by real-time PCR,the apoptosis of the transfected cells was detected by flow cytometry and the inhibition ratio of cell proliferation was detected by methyl thiazolyl tetrazolium (MTT).Results The expression of RGC32 gene was upgraded in pulmonary adenocarcinomas tissues(1:2.2736,t=-29.185,P=0.01).After RNA interference,the expression of RGC32 gene transfected A549 cells was down-regulated significantly[(2.47±0.17)％ vs(4.65±0.26)％,t=-202.868,P=0.000].Comparing to the control cells,the apoptosis of experimental group cells increased significantly (2.9 ％ vs 45.4 ％,t=-37.915,P=0.01),and the inhibition ratio of cell proliferation increased significantly.Conclusion The expression of RGC32 gene shows an obvious upgraded in pulmonary adenocarcinoma.The low expression of RGC32 gene can induce apoptosis and inhibit proliferation of A549 cells.
