ObjectiveTo investigate the effect of milk and milk products on morphological structure and epidermal growth factor (EGF) of non-steroidal anti-inflammatory drugs (NSAIDs) induced small intestinal damage in animals.Methods Eighty male SD rats were randomly divided into 5 groups:control group,diclofenac group,diclofenac with 10% low fat milk group,diclofenac with 10% colostrum group and diclofenac with yoghurt group.The animals with milk or colostrum or yoghurt were fed for 5 days before the administration of diclofenac with 15 mg/kg by gavage,once.Then they were observed the scores of anatomical lesion and the scores of tissue damage of mucous membrane and the height of villous at the 24th and 48th hour after making the models.Observation of the change of ultrastructural organization of mucous membrane was carried out with transmission and scanning electron microscope and immunohistocbemistry of EGF.Results The scores of anatomical lesion and tissue damage of mucous membrane of the colostrum group were lower than those of the diclofenac group ( P ＜ 0.05 ).The heights of the pile on small intestine of the24th and 48th hour of the colostrum group were (145.7 ± 16.5) μm and (139.2 ± 19.0) μm,respectively.They were higher than those of the diclofenac group[( 119.2 ± 19.2 ) μm and ( 105.4 ± 18.4 )μm,P ＜ 0.05].However there was no difference of the scores and the height among diclofenac group,milk group and yoghurt group.TEM and SEM of tissues showed that the cytoplasmic membrane and other cellular components of villous epithelial cells were well preserved in colostrum group,and the microvilli in the milk group and yoghurt group were ablated more obviously.The positive area of EGF of small intestine [(6170.5 ± 1483.9) μm2]were higher 48 h after administration of diclofenac compared with the diclofenac group ( P ＜ 0.05 ).The expression of EGF in milk and yoghurt group were no significant statistical difference with the diclofenac group.ConclusionBovine colostrum may have a beneficial effect in prevention of NSAIDs induced small intestinal injuries and preserve mechanical barrier of small intestinal mucosa which is probably relative to EGF.

Two kinds of different functional groups modified RuBpy-doped silica fluorescent nanoprobes Probe A and B that conjugated with avidin were prepared for the recognition of liver cancer cells. Firstly RuBpy-doped silica nanoparticles were synthesized by reverse microemulsion and modified with different functional groups, then Probe A was prepared by the conjugation of avidin with carboxyl modified nanoparticles through covalent binding using 1-ethyl-3-( 3-dimethylamino propyl ) carbodiimide hydrochloride ( EDC )/sulfo-NHS, whereas Probe B was prepared by the conjugation of avidin with the polyethylene glycol ( PEG) linkers on the surface nanoparticles using cyanogen bromide method. Therefore, compared with Probe A, Probe B was obtained by coupling avidin to the nanoparticles through long-chain PEG molecules. The two probes were incubated with liver cancer cells respectively, and microscopic fluorescence imaging shows that Probe B which contained PEG molecules could be more effectively applied for the recognition of tumor marker carcinoembryonic antigen ( CEA) in liver cancer cells.

Objectives To explore the relationships between the current physical exercise behaviors and psychological factors of middle school students,so as to provide scientific evidence for improving health education and carrying out targeted health intervention measures.Methods The Multi-stage stratified sampling and cluster sampling method was adopted to choose 3600 students from 12 junior and senior middle schools in Hangzhou,Wuhan and Xi'an.The date was collected using the adolescent physical exercise behavior-psychological measurement scale(Chinese version).The structural equation model was built to explore the relationships between psychological factors(including the change of strategy,decision balance positive effect,decision balance negative effect and self-efficiency)and physical exercise.Results The change of strategy has biggest effect on physical exercise behaviors,with the standardized direct effect value of 0.344.The standardized direct effect value of decision balance negative effect,decision balance positive effect and self-efficiency were 0.071,0.093 and 0.169 respectively.The negative correlation among the four dimensions was significant statistically.Conclusion Psychological factors have direct effects on the change of the behaviors,and the change of the strategy has the largest impact on physical exercise behaviors of middle school students.The four psychological factors are closely correlated with one another,which is important in formulating middle school sports programs to promote the physical quality of middle school students.

Abstract: Objective To investigate the prevalence and influencing factors of depressive symptoms among primary and middle school students in Xihu District, Hangzhou City, so as to provide insights into depression control among primary and middle school students. Methods: Students were sampled from two primary schools, two junior high schools, two ordinary high schools and one vocational high school in Xihu District using a stratified cluster random sampling method from September to November, 2021. Participants' demographics, diet, exercise, sleep and campus bullying were collected using questionnaire surveys. The depressive symptoms were evaluated using the Chinese version of the Center for Epidemiologic Studies-Depression Scale (CES-D), and factors affecting the depressive symptoms were identified among primary and middle school students using a multivariable logistic regression model. Results: A total of 1 518 students were investigated, including 518 primary school students (34.12%), 363 junior high school students (23.91%), 463 ordinary high school students (30.50%) and 174 vocational high school students (11.46%). Of all participants, there were 805 males (53.03%). The prevalence of depressive symptoms was 38.87% among the participants, and was 36.10%, 42.42%, 42.33% and 30.46% among primary school, junior high school, ordinary high school and vocational high school students, respectively. The multivariable logistic regression analysis showed that gender (OR=1.601, 95%CI: 1.289-1.989), type of school (junior high school, OR=1.299, 95%CI: 0.974-1.734; ordinary high school, OR=1.351, 95%CI: 1.025-1.780; vocational high school, OR=0.862, 95%CI: 0.585-1.272), frequency of fresh vegetable intake (less than once daily, OR=0.454, 95%CI: 0.304-0.679; once and more daily, OR=0.359, 95%CI: 0.235-0.548), duration spent on the internet (0.5 to 1 h daily, OR=1.447, 95%CI: 1.044-2.006; 1 h and longer daily, OR=1.456, 95%CI: 1.072-1.978), sufficient sleep (OR=0.525, 95%CI: 0.371-0.744), suffering from campus bullying (OR=1.992, 95%CI: 1.491-2.661) were associated with the development of depressive symptoms. Conclusions The prevalence of depressive symptoms is high among primary and middle school students in Xihu District. Gender, type of school, dietary behaviors, sleep duration and campus bullying are factors affecting the development of depressive symptoms.

Objective To analyze the characteristics and influencing factors of sleep disorders and nocturnal hypoxemia of patients with different degrees of obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Four hundred and twenty-five patients with snoring were scored by Epworth Sleepiness Scale ( ESS), and monitored by polysomnography (PSG). The possible correlations between sleep structure, hypoxia parameters, ESS and clinical features were analyzed and compared in those patients. Results Four hundred and twenty-five patients were divided into 4 groups according to the apnea-hypopnea index (AHI). There were 65 primary snoring patients (15.3%) and 360 OSAHS patients (84. 7% ) including 187 patients (44. 0% ) in severe OSAHS group. ESS was increased as aggravation of OSAHS. There were significant statistical differences in ESS among each group. Compared with primary snoring group, sleep efficiency, NREM1 + 2, oxygen desaturation index ( ODI), time with pulse oxygen saturation below 90% (T(SpO2 <90% ) ) were significantly higher in the OSAHS groups, and NREM3 +4, lowest pulse oxygen saturation level ( LSpO2 ) were lower. ESS was correlated positively with AHI (r= 0. 474,P <0. 01 ). They were both correlated positively with ODI, T (SpO2 <90% ) and NREM1 + 2( ESSr =0. 392, 0. 356,0. 194;AHI r = 0. 714, O. 682, 0. 365, all P < 0. 01 ), and correlated negatively with LSpO2, NREM3 + 4 ( ESS r = - 0. 414, - 0. 196; AHI r = - 0. 740, - 0. 385, both P < 0. 01 ). LSpO2, ODI and T (SpO2 < 90% ) were the primary influencing factors. Common clinical presentations and subjective symptoms were presented including daytime sleepiness, impaired memory, fatigue, dry mouth, oppressive wake and morning headache, etc. Percentage of individuals with daytime sleepiness in the severe OSAHS group was 73. 3% (137/187). These had serious impact on the patients' quality of life, leading to difficulty concentrating, poor memory and cognitive impairment. Conclusions Sleep disorders are found in the patients with different degrees of OSAHS. The excessive daytime sleepiness interrelated partly with the structure of sleep, and totally with hypoxia parameters. The more severity the patients have, the more nocturnal hypoxia, sleep disorders and higher ESS are found.
