AIM:To reveal the characteristics and patterns of mental activity in the cerebral cortex of patients with attention deficit hyperactivity disorder (ADHD) and explore the pathogenetic characteristics of ADHD.METHODS: The ADHD patients were asked to record their mental activity, general health condition and obsessions before the onset of pathological symptoms by means of psychological introspective reports.RESULTS: The direct cause of attention distraction and failure of attention focus is the patients' inability to perform cognitive tasks (including perception, memory and recollection, imagination, association and thought)in a continuously ongoing manner in relaxation. The frequent stagnancy and pause during the course of recognition precipitated the patients in a stressful state, which contributed to the onset of various hyperactivities and also resulted in the acquisition of "silent verbal thinking". This is an important psychopathological phenomenon long been neglected. All theses abnormalities caused the patients much discomfort, which was naturally relieved by means of impulsive and irritable behaviors.CONCLUSION: A series of clinical symptoms of ADHD arises from the same pathogenic factor of difficulty in mental activity and inability to carry out the activities in the cerebral cortex in a relaxed manner. The difficulty in mental activity is the key problem of ADHD and the source of various synptoms, which should be ;reated for the first place. The cause of this key problem is possibly lowered metabolism of the cerebral cortex, and the effect of "instinct" can not be neglected in the attempt to explain the pathogenesis of ADHD.

Objective To observe high glucose induced expression of hepatocyte growth factor (HGF) and c met in human kidney fibroblast. Methods The effects of glucose concentrations on expression of HGF, c met and plasminogen activator inhibitor (PAI) 1 in cultured human kidney fibroblasts were observed by RT PCR. In the same system, the effect of exogenous HGF on the expression of PAI 1 was investigated. Results Human kidney fibroblasts cultured in high glucose concentration (25 mmol/L) showed higher HGF and c met expressions in the early stage and then manifested a gradient decrease of HGF and c met expressions, but PAI 1 expression was gradiently increased. Exogenous HGF resulted in inhibiting PAI 1 expression. Conclusion HGF is a potential anti fibrogenic factor and activates matrix degradation pathways in diabetic kidney by reducing PAI 1 expression.

Objective:
To understand prevalence and influencing factors of abnormal spinal curvature in primary and secondary school students aged 10-14 years in Inner Mongolia, and to provide reference for relevant measures.
Methods:
A total of 92 094 primary and secondary school students aged 10-14 years were selected by multi stage cluster sampling, and were investigated with questionnaire.
Results:
A total of 1 957 participants (2.13%) with abnormal spinal curvature were detected, including 1 768( 90.34 %) with scoliosis. Significant differences in the detection rate of abnormal spinal curvature were observed among students with different myopia status and posture of sitting and standing ( χ 2=23.82, 9.84, P <0.05). Logistic regression analysis showed that different ethnic groups, monitoring points, age and area were main factors for risk of spinal curvature abnormalities in primary and secondary school students aged 10-14 years; good nutritional status, left right rotation of class seats, seat height adjustment according to height were associated with lower rate of spinal curvature abnormalities ( P <0.05).
Conclusion
Various measures should be taken simultaneously to reduce the prevalence of abnormal spinal curvature in primary and middle school students aged 10-14 years.

Objective:
To investigate the incidence of abnormal spinal curvature and related factors among middle school students in the Inner Mongolia Autonomous Region, so as to provide evidence for abnormal spinal curvature prevention and treatment.
Methods:
By using a random stratified cluster sampling method, 87 908 students of middle and high school students from all 12 counties(districts) were investigated via questionnaires for abnormal spinal curvature and health influencing factors in Inner Mongolia Autonomous Region. Chi square test was used to perform demographic characteristics and univariate analysis, and binary multivariate Logistic regression model was used to screen the risk factors for spinal curvature abnormalities in middle school students.
Results:
A total of 3 131(3.56%) students with spinal curvature abnormalities were detected, with boys (3.69%) higher than that of girls(3.44%), urban areas (6.15%) higher than that of the suburban counties (2.50%), and high school students ( 4.97 %) higher than that of junior high school(2.73%) students( χ 2=4.01, 702.19, 299.36, P <0.05). The detectable rate of spinal curvature abnormalities increased with grade ( χ 2 trend =309.29, P <0.05). Logistic regression analysis showed that factors influencing abnormal spinal curvature included myopia, overweight, obesity, the frequency of classroom seating arrangements, time spent on homework/reading after school every day, time spent in daytime outdoor activities, self imposed requirements for posture of sitting and standing, phase of studying, gender, and area ( OR =0.53-2.55, P <0.05).
Conclusion
Abnormal spinal curvature is strongly correlated to nutritional status, myopia, sitting posture when reading and writing, sedentary time, and time spent in outdoor activities. The collaboration of multiple departments is required to establish anenvironment to protect the spine, early detection and early intervention.

Objective:
To investigate the correlation between school bullying and depressive symptoms comorbidity and dietary patterns among middle school students in Inner Mongolia Autonomous Region from 2021, so as to provide reference for the prevention of school bullying and depressive symptoms.
Methods:
In September 2021, stratified random cluster sampling was used to select 87 414 middle school students in 12 leagues in Inner Mongolia Autonomous Region. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess depression, and the bullying was determined according to the items related to bullying in the program of Chinese National Surveillance on Students Common Diseases and Risk Factors.
Results:
In 2021, the detection rate of depressive symptoms among middle school students in Inner Mongolia Autonomous Region was 15.24%, school bullying was 3.02%, and the co-occurrence of school bullying and depression was 1.64%. Binary Logistic regression analysis showed that junior high school students ( OR =1.52) and girls ( OR =1.10) were more likely to suffer from comorbidity of school bullying and depression ( P < 0.05). Eating fried food less than one and more than once a day, smoking and drinking were positively correlated with school bullying and depression comorbidity ( OR =2.15,2.11,2.14,1.70, P <0.05).
Conclusion
The combination of bullying and depression among middle school students in Inner Mongolia Autonomous Region is affected by various dietary methods. In terms of diet, reducing the intake of fried food, no smoking, no drinking can effectively reduce the incidence of co-occurrence school bullying and depression.
