Objective To understand the prevalence of negative life events and its association with depressive, anxiety symptoms and dissatisfaction of school life among middle school students in Shaoxing, and to provide scientific evidence for further interventions. Methods A total number of 3 197 students (including 1 134 urban and 2 063 town adolescents) were recruited from 2 middle schools in Shaoxing, their average age was (13.73 ± 1.03) years. The Multidimensional Life Events Rating Questionnaire for Middle School Students (MLERQ), Depression Self-rating Scale for Children (DSRSC) and Screening for Child Anxiety Related Emotional Disorders (SCARED) were used to assess the mental health status, while the school life satisfaction was evaluated by the School Life Satisfaction Rating Questionnaire for Adolescents (SLSRQA), and the data were analyzed by descriptive statistics and multivariate logistic regression models. Results The prevalence of the negative life events was 84.9%, unsatisfactory examination performance (48.6%), unreached the teacher's expectation (46.2%), parental chatter (41.4%), unbalanced learning (37.9%), and getting parents scold (27.6%) constituted the main negative life events. The prevalence of depressive symptom, anxiety symptom, and dissatisfaction of school life were significantly higher among middle school students living with negative life events (41.1%, 22.6%, 26.0%) than those without negative life events (20.9%, 3.5%, 16.5%), (?2=71.33, 94.78, 19.83, P<0.001). The prevalence of the psychosomatic health involvement significantly increased with the increase of the number of the dimensions and events (P<0.001). The multivariate logistic regression showed that negative life events were the risk factors of depression, anxiety and dissatisfaction of school life. Their OR values were 2.483 (1.951-3.160), 7.245 (4.411-11.899) and 1.733 (1.325-2.267), respectively. The risk of occurring mental symptoms among children with the number of dimensions≥4 and/or the number of events≥12 was two times higher than those of children without such increase in numbers of dimensions and events. Conclusion The status of negative life events is serious among middle school students in Shaoxing. There are statistical associations between negative life events and mental symptoms.

Objective To evaluate the predictive effect of Braden scale for the risk of development of pressure ulcers (PU) in the department of neurology bedridden patients and to explore subgroup preventive measures. Methods 400 cases newly hospitalized bedridden patients in the department of neurology were collected with no pressure ulcers at the first evaluation and pressure ulcer risk was continuously predicted by a Braden scale skin assessment. The high-risk, middle-risk and low-risk groups were randomized into the experimental group and the control group respectively. Routine preventive measures were taken for the control group while the air fluidized bed for the high-risk group, the sponge mattress for the middle-riskgroup, and turning the body over every 4 hours for low-risk group. Other preventive procedures were undertaken simultaneously in beth the experimental and the control groups. Results The area under the ROC curve (AUC)was 0.771 and 0.828 at the first and last time Braden scale scores respectively. Such vMues as sensitiveness, specificity, positive predictive value, negative predictive value were found in higher level,when the diagnosis value was 17. There was no significant difference of incidence rate of the subgroup pressure ulcers between the high-risk, middle-risk, low-risk groups compared to the control group. Conclusions The effect of predicting pressure ulcer risk for bedridden patients in the department of neurology with Braden scale was fairly good, while the score 17 as the diagnosis value was ideal. The air fluidized bed for the high-risk group and the sponge mattress for the middle-risk group resulted in no significant decrease of incidence rate of the pressure ulcer, while taming over the patients' body every 4 hours for low-risk groups showed acceptable and therefore saving medical resources.

Objective To investigate the genomic amplification of the human telomerase RNA component (hTERC) gene in cervical cytology and evaluate its role in screening of cervical lesions. Methods A total of 301 cases were recruited, with liquid-based cytology diaghoses as normal (n=203), atypical squamous cells (ASC, n=66), low-grade squamous intraepithelial lesions ( LSIL,n=18), and high-grade squamous intraepithelial lesions ( HSIL, n=14). Following cytological examination, the slides were analyzed using a two-color fluorescence in aitu hybridization ( FISH ) probe targeted to chromosome 3q26 containing hTERC. The hTERC findings were compared to the cytologic and histologie results, as well as high-risk human papilloma viruses (HPV) results. Results Genomie amplification of hTERC was found in 3.0% (6/203)of normal specimens, 21.2% (14/66) of ASC, 44.4% (8/18) of LSIL and 92.9% (13/14) of HSIL, with a significant difference in each pair wise (all P<0.05). Significantly more cells with 3q26 gain were found in cervical intraepithelial lesion (CIN) Ⅱ than in CIN Ⅰ(75.0% vs. 20.0% ), as well as in CIN Ⅲ (86.7% vs. 20.0% ) and squamous cervical cancer (SCC) than in CIN Ⅰ (100.0% vs. 20.0%) ( all P<0.01). The sensitivity of hTERC amplification was significantly higher than cytological screening (82.6% vs. 17.4%, P<0.01), and its specificity was higher than high-risk HPV test (67.8%-73.5% vs. 25.6%-27.7%, P<0.01) in the diagnosis of HSIL (CIN Ⅱ - Ⅲ). The abnormal hTERC signal type mostly was 2:3 in CIN Ⅰ (84.9% ) ; whereas in CIN Ⅱ-Ⅲ, 2: 3, 2:4 and 4:4 accounted for 44.6%, 24.8% and 17.8%, respectively. Conclusion Testing the gain of chromosome 3q26 in cytological specimens using specific probe for hTERC is powerful in screening of HSIL, and the amplification patterns of 2:4 and 4:4 may serve as potential prognosis markers.

OBJECTIVETo establish a HPLC method to determine the carnosic acid in the stomach and intestine of rats and study its tissue distribution characteristics.

METHODAfter intragastric administration of carnosic acid (90 mg x kg(-1)), rats for each time-point were sacrificed by decapitation. After removal of the blood, various tissues were rapidly removed and weighted, all tissues were treated with a series of pretreatment before HPLC. Chromatographic separation was achieved on a Kromasil C18 column (4.6 mm x 150 mm, 5 microm) protected by an ODS guard column at 25 degrees C, using acetonitrile-0.1% phosphoric acid solution (55:45) as mobile phase, at a flow rate of 1 mL x min(-1). The wavelength of the UV detector was set at 210 nm for carnosic acid and internal standard.

RESULTGood linearities were obtained in every tissue over a range of 0.3212-160.6 mg x L(-1). The recovery, intra-day and inter-day precision and accuracy of three concentrations of carnosic acid in tissues met the requirements of methodology. And the stability of the tissue samples were also validated. The results of distribution in stomach and intestine showed that the highest concentration was (307.1 +/- 119.2) microg x g(-1) in stomach and (33.32 +/- 17.70) microg x g(-1) in intestine after intragastric administration of carnosic acid.

CONCLUSIONThe HPLC method was established to determine the concentration of carnosic acid in tissues. This method is quick, precise, and reproducible. It is the first time to study the tissue distribution of carnosic acid in rats after intragastric administration.

Objective: To examine the association between parent-child relationships and bullying behaviors among junior high school students, and to explore the moderating effect of community cohesion, so as to provide evidences for bullying intervention strategies. Methods: From November to December 2017, a cluster sampling method was used to survey 1 589 students in grades 6- 8 from three junior high schools in Jing an District,Shanghai. Anonymous electronic questionnaires collected data on parent-child relationships, community cohesion, and bullying behaviors. Multivariate Logistic regression analyzed the associations and moderation effects. Results: The prevalence of bullying behaviors among junior high school students was 7.80%. Spearman correlation analysis revealed negative associations between both parent-child relationships ( r =-0.13) and community cohesion ( r =-0.10) with bullying behaviors, while parent-child relationships positively correlated with community cohesion ( r =0.29) (all P <0.01). Junior high school students with positive parent-child relationships and higher perceived community cohesion showed lower risks of bullying behaviors ( OR=0.51, 95%CI =0.36-0.72; OR=0.58, 95%CI =0.45-0.76), with a significant interaction effect between the two factors (all P <0.05). Conclusions Positive parent-child relationships and community cohesion are negatively associated with bullying behaviors in middle school students. Supportive family relationships help reduce bullying, while stronger community cohesion enhances the protective effect of positive parent-child relationships against bullying.
