Objective: To investigate anxiety life interference among primary and middle school students in Henan Province and its influencing factors, and to provide scientific basis for health education in primary and secondary school students. Methods: By using cluster sampling method, 3 573 primary school students and 2 748 secondary school students in Henan Province were investigated with Child Anxiety Life Interference Scale(CALIS), Resilience Scale for Chinese Adolescents(RSCA), Perceived Social Support Scale(PSSS), Self-Esteem Scale(SES), General Self-efficacy Scale(GSES). Results: There were significant differences in anxiety life disturbance in primary and middle school students by gender(t=2.07, P=0.04), school level(t=-2.29, P=0.02), degree of anxiety(F=119.93, P<0.01), educational level of fathers (F=13.38, P<0.01) and educational level of mothers(F=9.65, P<0.01). The degree of life disturbance caused by anxiety was negatively correlated with mental resilience, social support and self-efficacy(r=-0.25, -0.09, -0.12, P<0.01), and was positively related to self-esteem(r=0.23). Mental resilience (β=-0.21) significantly negatively predicted anxiety interference with life, while self-esteem (β=0.13) and social support (β=0.06) significantly positively predicted anxiety interference with life. Conclusion The life of primary and middle school students is seriously disturbed by anxiety, and mental resilience is the primary psychosocial factor that affects the level of anxiety life interference among primary and middle school students.

Objective: To investigate the current status and psychosocial determinants of health behavior among primary and middle school students in Henan province,and to provide a reference for the direction and priority of the health education in primary and middle schools. Methods: Through cluster sampling method, 3 603 primary school students age 9 to 15 and 2 791 secondary school students in Henan Province were investigated with Chinese version of the Adolescent Lifestyle Questionnaire(C-ALQ), General Self-efficacy Scale(GSES), Perceived Social Support Scale(PSSS), Resilience Scale for Chinese Adolescents(RSCA), Self-Esteem Scale(SES) during January to June in 2016. Results: The total score of health behavior among primary and middle school students was (80.30±16.36).There were significant differences in health behaviors among students with different gender(P<0.05), age(P<0.01), family income(P<0.01), body mass index(P<0.01), father’s education level (P<0.01) and mother’s education level(P<0.01). Health behaviors were significantly correlated with self-efficacy(r=0.26-0.42, P<0.01), social support(r=0.23-0.39, P<0.01), mental resilience(r=0.26-0.37, P<0.01), and self-esteem(r=-0.28--0.18, P<0.01). Gender, age, family monthly income, BMI, parents’ education level, self-efficacy, psychological resilience, social support and self-esteem was psychosocial determinants of healthy behaviors(P<0.05). Conclusion The engagement in health behaviors among primary and middle school students in Henan province is acceptable. Demographic and psychosocial determinants of health behaviors among primary and middle school students should be considered in health education curriculum planning.

Objective: To understand the current status of health related quality of life among primary and middle school students aged 9 to 15 years old in Henan Province, and to explore its relationship with negative emotions and social support. Methods: Between January and June 2016, 24 primary and middle schools were selected from 6 cities of Henan Province, and 5 867 primary and middle school students were included and completed the Pediatric Quality of Life Inventory Measurement, Stress Anxiety Depression Scale, Perceived Social Support Scale. Hierarchical linear regression analysis was used to examine the moderating effect of social support. Results: The total score of health related quality of life of primary and middle school students in Henan was (81.21±12.49). There were statistically significant differences in the quality of life among primary and middle school students with different gender, study period, family monthly income, subjective parental relationship and parental education ( P <0.05). Negative emotions were negatively correlated with quality of life ( r =-0.51, P <0.01) and social support ( r =-0.30, P <0.01), while social support was positively correlated with quality of life ( r =0.29, P <0.01). Regression analysis showed that negative emotional was negatively associated with quality of life ( β =-0.23, P <0.01), while social support was positively associated with quality of life ( β =0.16, P <0.01). The interaction of negative emotions and social support was negatively associated with quality of life ( β =-0.18, P <0.01). Conclusion Health related quality of life among 9-15 year old primary and middle school students in Henan province is satisfactory. Social support might buffer the negative impact of negative emotions including depression, anxiety and stress on quality of life of primary and secondary school students.

ObjectiveTo investigate the clinical pharmacokinetics (PK) and pharmacodynamics (PD) of gemifloxacin tablet in healthy Chinese volunteers and to provide evidences for optimal clinical dosing.MethodsTwenty volunteers were enrolled in the randomized (1∶1) double-blind study,and divided into administration group and control group.Each group received multiple oral doses of 320 mg of gemifloxacin tablet or placebo.The plasma and urine samples for gemifloxacin were analyzed by igh-performance liquid chromatogram(HPLC)-fluorometricmethod. Theminimuminhibition concentrations (MIC)of gemifloxacin against190clinical isolateswere determinedby broth microdilution method.The fAUC0～24 h/MIC and fCmax/MIC,with target value of 25 and 5,were used as the indices to evaluate PK and PD characteristics of gemifloxacin. The cumulative fraction of response (CFR) of gemifloxacin against each bacterium and the probability of target attainment (PTA) under various MIC level were evaluated using Monte Carlo simulation following multiple administration at steady state.ResultsThe Cmax of gemifloxacin after once-daily oral doses for 7 days were (1.55 ±0.32) μg/mL and (1.57±0.31) μg/mL for the first and last dose,while the AUC0～24 h were (7.91±1.52) and (8.91±1.15) h · μg · mL-1,respectively.The accumulation factor was 1.13±0.05.The time-profile of gemifloxacin could be described using two-compartment model and the half-life of distribution and elimination phase were (0.64 ± 0.17) and (7.10 ± 2.10) h,respectively. The cumulative urinary excretion rates within 24 h of gemifloxacin were 34.83 ％ and 38.95 ％ for the first and the last dose,respectively.PD study showed that the MIC90 of gemifloxacin were 0.25 mg/L and 0.125 mg/L against Streptococcus pneumoniae and Moraxelle catarrhalis,respectively,while the MIC90 was 2 mg/L against Hemophilus influenza. However,most of Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus (MRSA) were resistant to gemifloxacin ( MIC90 ＞ 32mg/L).The PTA values of fAUC0～24 h/MIC and fCmax/MIC of gemifloxacin 320 mg daily for 7 days were close to 100％ when MIC was ≤0.06 mg/L.ConclusionsGemifloxacin is rapidly absorbed after oral administration of single doses in healthy Chinese volunteers,and the plasma concentration could reach steady state at the third day,while a minimal accumulation is shown after consecutive 7 days dosing.The PK/PD analysis suggests that the favorable clinical and bacteriological efficacy could be obtained when using thisregimen in treatment of sensitive patients with community-acquired pneumonia and acute exacerbation of chronic obstructive pulmonary disease.

Objective:To explore the relationship between the dark triad, basic psychological needs satisfaction and guilty proneness.Methods:Totally 595 college students were randomly selected from Zhengzhou University.They were tested with the dirty dozen(DD), the balanced measure of psychological needs scale(BMPN) and guilt-proneness-5(GP-5). SPSS 22.0 and AMOS 21.0 were used for data analysis, including descriptive analysis, correlation analysis and confirmatory factor analysis. Bootstrap measure was used for mediating effect test.Results:(1)The correlation analysis showed that the dark triad (29(21, 37)), Machiavellianism (4(4, 8)) and psychopathy(5(4, 9)) were negatively correlated with guilty proneness (20(16, 23)), and the correlation coefficients were -0.10, -0.22 and -0.18 respectively(all P<0.01). While narcissism (16(12, 21)) was not correlated with guilty proneness ( r=0.04, P>0.01). The satisfaction of basic psychological needs (56(54, 60)) was positively correlated with guilty proneness ( r=0.31, P<0.01). (2)The relationship between the dark triad and guilty proneness was partially mediated by basic psychological needs satisfaction, and the mediating effect accounted for 62.96%. Conclusion:The dark triad influences guilty proneness through basic psychological needs satisfaction.

OBJECTIVE: To discuss the disease incidence of bronchial asthma (BA) complicated with allergic rhinitis (AR) and the correlation of their age, classification, concomitant symptom. METHOD: Four hundred-nine cases of AR were identified by means of random sampling, physical examination, laboratory test and questionnaire. According to the diagnostic criteria of BA, they were divided into two groups: group I ( control group) including 298 cases suffering from only AR, group II ( experimental group) 191 cases of BA concomittent with AR. RESULT: 1) This study showed that BA concomittent with AR account for 39% of all cases; 2) Incidence of aspirin triad syndrome (asthma, rhinopolyps and aspirin intolerance) was significantly different in two groups (P<0.01); 3) As for age group distribution, there was significant difference between groups in age segment 10-19 and 40-49 (P<0.05); 4) Disease classification: there were significant differences in the incidence of moderate to severe intermittent AR, mild continuous AR, and moderate to severe continuous AR between two groups (P<0.05); 5) Other major concomitant diseases and symptoms distribution; the concomittant occurrence of allergic pharyngitis, sinusitis, conjunctivitis, secretory tympanitis, hypertrophic rhinitis, dermatosis, discomfort of gastrointestinal tract, and headache of unknown origin were significantly different between two groups (P<0.05). The difference above showed that the occurrence in experimental group was higher than that in control group. CONCLUSION the incidence of BA complicated with AR were relatively high in Datong, with a peak incidence at age 10 to 19 and 40 to 49. The common types of disease were moderate to severe intermittent AR, mild continuous AR, and moderate to severe continuous AR. The number of patients with BA complicated with AR were growing.
