Objective To evaluate the impact of psychological and behavioral intervention on self-concept of school- age children with asthma. Methods The intervention group and the control group in-cluded 50 patients each. Those in the intervention group attended a 6-month psychological behavioral inter-vention in addition to routine follow-up visit and inhalation therapy, while the control group received the routine follow-up visit and inhalation therapy only. Piers-Harris children's self-concept scale (PHCSS) was administered to evaluate the self- concept of the sample repeatedly at 3 months and 6 months. Data about the incidence times of asthma, time of absent from school and hospitalization time were collected within 6-month intervention. Results After 6- month intervention ,the incidence times of asthma and time of ab-sent from school in the intervention group were less San those of the control group. No statistical difference was seen in hospitalization time between the two groups. The total self- concept level and the scores of most subscales, including intelligence and academic competence, physical appearance and attribute, anxiety and popularity in the intervention group were higher than those of the control group. Conclusions Psycholog-ical behavioral intervention was effective in reducing psychosomatic effect of asthma, improving self-con-cept of school- age children with asthma, and promoting the physical and mental health of them.

Objective To establish an animal model of metabolic syndrome which is prone to atherosclerosis. Methods Eight rabbits were randomly selected from in total of 16 rabbits as control group who were fed with normal rabbit feed. And the rest were used as model group, who were fed with high fat diet. Animals were weigh every week, and triacylg-lycerol (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and glucose (GLU) content were tested in the 8th, 10th , 13th, 16th and 18th week. Femoral arterial blood pressure and insu-lin (INS) content were assessed at the end of experimental period which is the 18th week;Also, aortic sclerosis rating, arterial stiffness index, abdominal fat coefficient, liver coefficient and cardiac coefficient were calculated and heart, aorta, liver and lower extremity artery pathology were examed. Results Compared with the control group, weight in the model group in-creased significantly;Serum levels of TC, HDL-C, blood pressure abdominal fat coefficient, liver coefficient were significant-ly increased in model group;the whole blood viscosity, plasma viscosity and blood pressure fat coefficient, liver coefficient, aortic sclerosis rating, arterial stiffness index, and GLU all increased significantly in model group;while HDL-C/TCHO, in-sulin sensitivity index decreased significantly in model group(P < 0.05 or P<0.01). Conclusion Food induced method can form metabolic syndrome and atherosclerosis in rabbit model.

The plasma levels of inflammatory cytokine interleukin-6 (IL-6) and anti-inflammatory cytokine interleukin-10 (IL-10) in the patients with unstable angina or stable angina were determined and compared. In 30 patients with unstable angina and 22 patients with stable angina, plasma levels of IL-10 and IL-6 were detected by ELISA and plasma lipid parameters by lipid research clinical methods respectively. The results showed plasma levels of IL-10 were significantly lower in unstable angina group than in stable angina group (P = 0.005), while those of IL-6 were significantly increased in unstable angina group as compared with those in stable angina group (P = 0.039). There was a significantly negative correlation between IL-10 and IL-6 in patients with unstable angina (r = -0.41, P = 0.003). In the unstable angina group, IL-6 levels were obviously positively correlated with TC (r = 0.314, P = 0.023), but not with TG and HDL. There were no significant correlations between IL-10 and plasma lipid parameters. It was suggested that the decreased IL-10 and increased IL-6 might be associated with the atheromatous plaque stability and progression of coronary heart diseases. IL-10 may play an important role in preventing coronary vascular lesions.

Objective To investigate the statistical methods used in nursing papers for bachelor's degree. Method We collected 160 nursing theses for bachelor's degree in 2016 in our college and analyze the statistical methods. Results A total of 80 papers used statistical methods consisting of statistical table, statistical inference, single factor analysis, variance analysis and statistical description. Among them, the statistical methods in 66 papers (82.5%) were misused. About 139 misuses of statistical tables was found in papers, and about 23 misuses of statistical inference in papers, taking up 45.4%. Conclusions The nursing undergraduates are familiar with the application of statistical methods, but the methods tend to be simple and unitary. Therefore, it is a need to enhance their practice in using statistical methods.

To study the application characteristics of copovidone (PVP-S630) in Xinyueshu extracts during the spray drying process, and its effect on such pharmaceutical properties as micromeritics and drug release behavior. PVP-S630 was added into Xinyueshu extracts to study on the spray drying, the effect of different dosages of PVP-S630 against the wall sticking effect of the spray drying, as well as the power property of Xinyueshu spray drying power and the dissolution in vitro behavior of the effective component of hyperoside. The results showed that PVP-S630 revealed a significant anti-wall sticking effect, with no notable change in the grain size of the spray drying power, increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior of hyperoside. It was worth further studying the application of PVP-S630 in spray drying power of traditional Chinese medicine.

NDV strain ZJ1 strain , a highly virulent NDV strain, has been prevalent among the waterfowls in China mainland in the past years. Multi-basic amino acid sequence distribute in the protease cleavage site of F protein of this strain. Recombinant expressing plasmid pCI-FT, was generated by converting multi-basic amino acid sequence of 112, 115, 117 of the protease cleavage site of F_ 0 protein, to the non-basic amino acid sequence characteristic of avirulent NDV strain. The result from co-expression of mutant or parental F protein with homologous HN protein in COS-1 cells revealed that both mutant and parental F protein had fusion activity. The result from co-expression of mutant or parental F protein with homologous HN protein in CEF cells showed that the cleavage activity of mutant F protein was significantly reduced. The study built a foundation for mutagenesis of amino acid sequence of the protease cleavage site of F_ 0 protein at the full-length cDNA clone level, study on factors contributing to virulence and construction of candidate vaccine strain, and so on.

The tumor multidrug resistance reversal effect of NPB304, a novel taxane, was studied. MTT assay was used to determine the IC50 of chemotherapy drugs. Western blotting assay was applied to analyze the expression of P-glycoprotein (P-gp). The effect of compounds on the P-gp function and P-gp ATPase activity was determined by rhodamine 123 (Rh123) accumulation assay and analysis kit, respectively. Molecular docking was employed to predict the binding force between compounds and P-gp. Transmembrane transport of NPB304 was analyzed using MDCK II and MDR1-MDCK II cell model. NPB304 displayed multidrug resistance reversal effect on KBV cells and MCF-7/paclitaxel cells, NPB304 collaborative with P-glycoprotein (P-gp) inhibitors verapamil enhanced the reversal activity, specifically, 10 μmol x L(-1) verapamil in combination with paclitaxel reversed resistance by 56.5-fold, while combined with NPB304 increased the reversal fold; NPB304 synergistically increased Rh123 accumulation in the resistant cells when combined with verapamil, and NPB304 at 0-1 μmol x L(-1) enhanced the ATPase activity activated by verapamil was observed. NPB304 existed the hydrophobic interactions with the TM regions of P-gp, and the binding force between NPB304 and the A chain of the TM region was stronger. P-gp ATPase activity assay demonstrated NPB304 at lower concentrations (0-1.5 μmol x L(-1)) could activate the P-gp ATPase, playing a role on inhibition of P-gp function. However, NPB304 did not have an obvious feature of P-gp substrate. NPB304 exerted itself and synergy with verapamil activity on reversing tumor resistance via inhibiting the P-gp function.
