Current status and influencing factors of health behaviors in stroke patients / 中华行为医学与脑科学杂志

Objective:To investigate the current status and influencing factors of stroke patients.Methods:Using stratified sampling method, 458 stroke patients was investigated for the health behavior from October to December, 2015. Based on PROCEDE-PROCEED model, logistic regression analysis was conducted with the health behavior level of the subjects as the dependent variable, and the characteristic factors in the chi-square test as the independent variables to analyze the factors which influence the health behavior level of stroke patients from predisposing factors, enabling factors and reinforcing factors.Results:The health behavior score of stroke patients was (14.5±3.9), which was at medium level. The score of each dimension was nutrition (0.80±0.25), disease management (0.60±0.26), interpersonal relationship (0.57±0.33), and medication compliance (0.49±0.41). The multiple logistic regression analysis showed that the predisposition factors including age ( OR=2.03, 95% CI=1.08-3.80) and history of hypertension( OR=2.35, 95%=1.16-4.76), the enabling factors including the allocation of social resources ( OR=1.73, 95% CI=0.89-3.36), and the reinforcing factors including family support ( OR=2.03, 95% CI=0.99-4.17) were important factors which affect the health behavior of stroke patients. Conclusion:The health behavior level of stroke patients need to be improved. The relevant community resource allocation system continuously, and focus on the impact of family environment and particularly the elderly and patients with a history of hypertension should be attentioned when improving the health behavior of patients.

Application and effect of transfer type anti-acupuncture needle in blood collection of hemodialysis patients / 实用医学杂志

Objective To improve the efficiency of blood collection in hemodialysis patients by inventing and applying new blood collection needles.Methods One hundred and eighty cases of hemodialysis patients were randomly divided into control group 1(CG1),control group 2(CG2),experimental group(EG). Comparison of the three groups in time of blood collection,the number of operation that had the risk of acupuncture injury and the number of the blood samples that had been contaminated. Results There were statistically significant difference (P<0.05)in three groups.The number of times of blood collection in the number of operations that had the risk of acupuncture injury,and the number of the blood sample that had been contaminated. CG1 had the longest blood collection time(12.55 min),EG had the shortest blood collection time(5.09 min);the risk of acupuncture injury was the highest in CG2 and the lowest in the EG.The number of contamination of blood samples and the amount of inaccurate sample in CG1 were the highest,and the lowest in the EG. Conclusions The working efficiency of transfer type anti-acupuncture needle(TTAN)during blood sample collection in hemodialysis patients is signifi-cantly better than that of traditional blood collection method,and it is helpful to reduce the risk of acupuncture injury and the risk of contamination in blood samples,which is worthy of promotion.

Investigation of Chinese Medicine Hospital Nurses' Requirement on Effect Evaluation of Traditional Chinese Medicine Nursing Program / 世界科学技术-中医药现代化

This study was aimed to investigate the requirement of our hospital nurses in the effect evaluation of fifteen traditional Chinese medicine (TCM) nursing programs,and to make it as the basis for making feasible evaluation tables of TCM nursing programs.The investigation survey was given among 78 nurses from the internal medicine ward,surgical ward and the department of orthopedics in our hospital.The questionnaire was graded according to the Likert 5 scoring method,including 3 themes and 11 items.The SPSS 17.0 package was used for statistical processing.The results showed that 93％ nurses participated in the training of effect evaluation table of unified TCM nursing program in the hospital or department,but the overall attitude was negative in terms of the operability and objectivity on the effect evaluation of the program.Requirements of guidelines for effectiveness evaluation of TCM nursing program showed that most nurses agreed that the new TCM nursing program needed to increase quantifiable indicators and to increase its objectivity and reproducibility.It was concluded that nurses generally considered that the evaluation system of nursing program of TCM had no quantitative indicators,but with strong subjective.In the clinical practice,it is in urgent need of an objective TCM nursing program with quantitative indicators and strong operability.

Expression of the reporter LacZ driven by human dentin sialophosphoprotein promoter in human dental mesenchymal cells / 生物工程学报

The expression of dentin sialophosphoprotein (DSPP) is the marker for cells differentiated into odontoblasts. This study attempted to analyze the DSPP promoter and build the reporter LacZ expression system driven by this promoter, which allows convenient and quick detection of odontoblast cells. First, we separated the human dental mesenchymal cells in which the expression of DSPP can be effectively induced by dexamethasone. Second, four 5' flanking regions of human DSPP gene (- 4 000-+54, -2 500-+54, -1 447-+54 and -1 027-+54) were analyzed, the results showed that the highest promoter activity lied in the -2 500-+54 region. The promoter activity is reduced when the 5' flanking region was extended from -2 500 to -4 000 bp upstream from the transcription start site; The promoter activity are also decreased when the 5' flanking regions were shorted from -2 500 to -1 447 bp and from -1 447 to -1 027 bp, indicating that potential suppresser elements are lied in the region between -4 000 and -2 500 bp and potential activator elements are lied in the region between -2 500 and -1 027 bp. Then we constructed the lentiviral report vector phDSPP-LacZ containing the -2 500-+ 54 promoter region in front of the LacZ gene. The expression of LacZ was detected using X-Gal staining in both human dental mesenchymal cells and immortalized human dental mesenchymal cells infected with phDSPP-LacZ. The phDSPP-LacZ lentiviral vector may provide a more convenient method to detect the expression of DSPP in human odontogenic differentiation, tooth development and tooth regeneration studies.

Tissue culture and polyploidy induction of Morinda officinalis / 中国中药杂志

<p><b>OBJECTIVE</b>To establish an effective protocol for plant generation and induce polyploidy of Morinda offcinalis.</p><p><b>METHOD</b>Callus was induced from immature embryo of M. officinalis and polyploidy was inducted by using colchicine treatment method. Chromosome was detected by flow cytometry.</p><p><b>RESULT AND CONCLUSION</b>The highest induction rate of polyploidy was 18.40%, which was obtained with 500 mg x L(-1) colchicine treatment for 5 days. Roots of polyploid were bigger than diploid. Advantages of using immature embryo as explants are easy for sterilization, higher rate of callus induction and low degree dedifferentiation. The induced polyploidy of M. officinalis may have a value for spread of cultivation.</p>
