ABSTRACT
Objective@#To investigate the longitudinal association between peer bullying victimization and internalizing symptoms, and to examine whether parental warmth buffers against this effect,so as to provide a reference for improving the mental health of the special group of children.@*Methods@#Students in grade 4 and grade 5 from three primary schools in Ma’anshan, Anhui Province were selected in Oct. 2017 with informed consent. Height, weight and pubertal development were objectively assessed. Internalizing symptoms and peer bullying victimization were evaluated at baseline and 1-year follow-up by using the MacArthur Health and Behavior Questionnaire-Child. Children were classified into three groups as non-bullying, non-consistent and consistent bullying victimization group. Multiple linear regression model was used to analyze whether the association between peer bullying victimization and internalizing symptoms varied across different parental warmth groups.@*Results@#Compared with non-bullying victimization group, consistent-and non-consistent bullying victimization had higher internalizing symptoms at baseline and 1-year follow-up(P<0.01). Students reported consistent, non-consistent bullying victimization under moderate parental warmth had lower internalizing symptoms at baseline and 1-year follow-up than those reported under low parental warmth group(P<0.01). Multiple liner regression showed that consistent bullying victimization [β=0.66(95%CI=0.33-0.99), 0.37(95%CI=0.15-0.59), 0.58(95%CI=0.31-0.84), P<0.05] and non-consistent bullying victimization[β=0.33(95%CI=0.18-0.47), 0.28(95%CI=0.13-0.41), 0.29(95%CI=0.08-0.51),P<0.05] were associated with higher 1-year follow-up internalizing symptoms in non-consistent, moderate-and low parental warmth group, while such association was not observed in consistent parental warmth group.@*Abstract@#The experience of peer bullying victimization increases the risk of internalizing symptoms and this finding suggests that parental warmth help to buffer children from the internalizing symptoms associated with bullying victimization.
ABSTRACT
Objective To determine the accuracy of intracavitary electrocardiogram bimodal P-wave and characteristic P-wave in the position of PICC tip. Methods In the process of ECG guided catheterization, the morphological changes of P-wave in the intracavitary electrocardiogram were observed, and the bimodal P-wave and characteristic P-wave were recorded. The corresponding catheter length of the bimodal P-wave and characteristic P-wave were recorded. CT three-dimensional reconstruction was performed on 416 patients who underwent CT examination before and after catheterization. The distance between carina of trachea to superior vena cava and the right atrium junction was measured as best position of PICC and the standard distance. After catheterization, the distance from the tip of catheter to the corresponding catheter length of the bimodal P-wave and characteristic P-wave was measured as actual distance, and compared with the standard distance. Results In 416 cases, 168 patients (40.38％) were bimodal P-wave, and the accurate rate of bimodal P-wave was 86.31％(145/416), and the accurate rate of the characteristic P-wave was 13.69％(23/416). The standard distance was (41.96 ± 9.16) mm, the actual distance of corresponding characteristic P-wave was (48.00±15.18) mm and bimodal P-wave was (45.10± 11.16) mm. The distance of bimodal P-wave to control was (1.31±0.33) mm and characteristic P-wave was (6.00 ± 2.88) mm, which was significant statistical difference (t =5.197, P < 0.05), and the standard deviation of the distance of bimodal P-wave to control was smaller (0.33 < 2.88). Conclusions The intracavitary electrocardiogram bimodal P-wave is more accurate than characteristic P-wave in the position of PICC tip and it supplements and improves thePICC's tip position.
ABSTRACT
Objective To investigate the clinical curative effects of Wuhaiyingliu Wan(WHW) plus Jiaheng (L-T4) therapy on simple goitre. Methods 120 patients with simple goitre were randomly divided into three groups, 39 cases were given WHW,39 eases were given L-T4 ,and 42 cases were given both WHW and L-T4. All patients' goi-tre volume were tested before initiating medication and 6 ～ 12 months after therapy to compare the medicative effects among the groups. Results There was no significant difference in goitre volume among the three groups before medi-cation. It was found that significant dimunution of gnitre volume in all groups, but similar dimunution in WHW and L-T4 group, significant diminution in combination group after 6 ～ 12 months of initiating medication(P < 0.01). Conclu-sion WHW ean diminish goitre volume in short term,its medicative effect is similar to L-T4 ,conjoint use will boost its effect on gnitre volume,it is a good therapeutic method to be gnneralized.
ABSTRACT
OBJECTIVE To analyze the reason of the wet pack after steam sterilization,in order to put forward the countermeasures and apply them to our work for reducing the number of wet pack. METHODS The results of wet pack were evaluated from May 2005 to Aug 2007 retrospectively.The countermeasures were applied to our work from Sep 2007 to Mar 2008 and compared with before(from Jan to Aug). RESULTS There were 1943 wet packs appeared,the wet pack ratio was 0.37%.Reasons of the wet pack including the factors about sterilizer(35.1%),load(33.12%),preparedness(25.68%) and cooling(6.10%).The ratio of wet pack had decreased from 0.32% to 0.11% after controls(? 2 = 42.5,P
