Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To explore the birthdate circuit qi endowment of the five circuit phases and six climatic factors in the female patients with benign and malignant breast tumors,and to analyze the benign and malignant tendency of breast tumors.Methods The birth date information of 723 patients with breast malignant tumor(breast cancer)and 1 595 patients with benign breast tumor were collected from the electronic medical record system of the First Affiliated Hospital of Guangzhou University of Chinese Medicine.SPSS 25.0 statistical software was used to analyze the circuit qi information of the two groups of patients.Results(1)The analysis of suiyun(yearly evolutive phase)showed that the patients born in the years of excessive wood phase,excessive fire phase,and deficiency earth phase tended to suffer from breast cancer,while the patients born in the years of deficiency gold phase,deficiency wood phase,and excessive water phase tended to suffer from benign breast tumors.(2)The analysis of dominant qi(regular yearly circuit qi)showed that the patients born at the time of shaoyin monarch fire were more likely to suffer from breast cancer,while patients born at the time of jueyin wind-wood and taiyin damp-earth were more likely to suffer from benign breast tumors.(3)The analysis of guest qi(alterable yearly circuit qi)showed that the patients born at the time of jueyin wind-wood and yangming dry-gold were more likely to suffer from breast cancer,and the patients born at the time of shaoyang ministerial fire and taiyang cold-water were more likely to suffer from benign breast tumors.(4)The analysis of birth season showed that the patients born in spring were more likely to suffer from breast cancer.(5)The analysis of the combination of circuit and qi(circuit phases and climatic factors)showed that the patients born in the year of xiaoni(circuit phases generating climatic factors),buhe(circuit phases restricting climatic factors),and tianxing(sitian climatic factors restricting the predominant circuit phases)tended to suffer from breast cancer,and patients born in the year of suihui(yearly heavenly-stem circuit phase accorded with the yearly earthly-branch circuit qi)and tongsuihui(deficiency yearly circuit phase in accordance with the second half of the alterable yearly circuit qi)tended to suffer from benign breast tumors.(6)The analysis of celestial control-terrestrial effect showed that the combination of celestial control-terrestrial had no significant effect on the incidence of breast cancer or benign breast tumors(P＞0.05).Conclusion(1)Certain differences and tendencies of birthdate circuit qi endowment exist between benign breast tumors and breast cancer.(2)The birthdate circuit qi endowment of breast cancer is characterized by wind and heat,and mainly involves liver,spleen,heart and kidney.Compared with patients with benign breast tumors,patients with breast cancer usually have the excess and heat biased constitution endowment.

Objective:To investigate the changes of hippocampal gray matter volume and expression of candidate immune related genes in a rat model of schizophrenia established by repeated administration of dizocilpine(MK-801).Methods:Thirty SPF grade Sprague-Dawley male rats at postnatal day 28 were randomly divided into MK-801 medium-dose (0.25 mg/kg) group, MK-801 high-dose(0.50 mg/kg) group and normal saline (5 mL/kg) group according to random number table method, with 10 in each group.Rats were given continuous intraperitoneal administration according to grouping once a day for 14 days.Open field test, novel object recognition test and Y-maze test were used at postnatal day 60 to detect spontaneous activity, exploration ability, anxiety level, object recognition memory ability and spatial working memory of rats, respectively.At postnatal day 67, structural magnetic resonance imaging was used to detect the changes of hippocampal gray matter volume in rat.And at postnatal day 70, qRT-PCR was used to detect the expression of candidate immune-related genes in rat hippocampus.SPSS 25.0 was used for statistical analysis, one-way ANOVA was used for comparison among multiple groups, and Tukey test was used for further pairwise comparisons.Results:(1)The behavioral results showed that there were significant differences in the total movement distance, central area activity time, novel object recognition index, and spontaneous correct alternation rate among the three groups ( F=11.15, 10.11, 13.62, 11.99, all P<0.05). The total movement distances in MK-801 medium-dose group and MK-801 high-dose group ((21.44±2.17) m, (22.87±1.96)m) were higher than that in the normal saline group ((18.70±1.88) m) (both P<0.05). The activity time of the central area in the MK-801 medium-dose group and MK-801 high-dose group((3.24±1.58) s, (2.50±1.32) s) were lower than that of the normal saline group ((6.05±2.48)s) (both P<0.01). Novel object recognition indexes in the MK-801 medium-dose group and MK-801 high-dose group((56.10±3.99)%, (54.00±6.41)%) were both lower than that in the normal saline group ((65.90±5.65)%)(both P<0.01), and the rates of spontaneous correct alternation ((54.60±7.03)%, (51.60±8.84)%) in the two groups were lower than that of the normal saline group ((68.40±8.57)%) (both P<0.01). (2) The results of structural magnetic resonance imaging showed that there were significant differences in the volume of hippocampal gray matter among the three groups ( F=9.24, P<0.001). The volumes of hippocampal gray matter in MK-801 medium-dose group and MK-801 high-dose group were lower than that in normal saline group(both P<0.001). (3)By constructing protein-protein interaction network, four candidate immune related genes were screened out: neuropeptide Y (NPY), somatostatin (SST), cholecystokinin (CCK) and tachykinin 1 (TAC1). The results showed that the mRNA expression levels of NPY, SST and CCK in the hippocampus of the three groups were significantly different ( F=11.41, 10.43, 5.85, all P<0.05), but there was no statistical difference in the TAC1 mRNA expression level ( F=0.08, P>0.05). The mRNA levels of NPY, SST and CCK in the hippocampus of rats in the MK-801 high-dose group were lower than those in the normal saline group (all P<0.05). Conclusion:Both medium dose and high dose MK-801 administration can reduce the volume of hippocampal gray matter in schizophrenia model rats, but they have different effects on the expression of hippocampal immune related genes, of which high dose administration has a greater effect.

Objective: To development the prognostic nomogram for malignant pleural mesothelioma (MPM). Methods: Two hundred and ten patients pathologically confirmed as MPM were enrolled in this retrospective study from 2007 to 2020 in the People's Hospital of Chuxiong Yi Autonomous Prefecture, the First and Third Affiliated Hospital of Kunming Medical University, and divided into training (n=112) and test (n=98) sets according to the admission time. The observation factors included demography, symptoms, history, clinical score and stage, blood cell and biochemistry, tumor markers, pathology and treatment. The Cox proportional risk model was used to analyze the prognostic factors of 112 patients in the training set. According to the results of multivariate Cox regression analysis, the prognostic prediction nomogram was established. C-Index and calibration curve were used to evaluate the model's discrimination and consistency in raining and test sets, respectively. Patients were stratified according to the median risk score of nomogram in the training set. Log rank test was performed to compare the survival differences between the high and low risk groups in the two sets. Results: The median overall survival (OS) of 210 MPM patients was 384 days (IQR=472 days), and the 6-month, 1-year, 2-year, and 3-year survival rates were 75.7%, 52.6%, 19.7%, and 13.0%, respectively. Cox multivariate regression analysis showed that residence (HR=2.127, 95% CI: 1.154-3.920), serum albumin (HR=1.583, 95% CI: 1.017-2.464), clinical stage (stage Ⅳ: HR=3.073, 95% CI: 1.366-6.910) and the chemotherapy (HR=0.476, 95% CI: 0.292-0.777) were independent prognostic factors for MPM patients. The C-index of the nomogram established based on the results of Cox multivariate regression analysis in the training and test sets were 0.662 and 0.613, respectively. Calibration curves for both the training and test sets showed moderate consistency between the predicted and actual survival probabilities of MPM patients at 6 months, 1 year, and 2 years. The low-risk group had better outcomes than the high-risk group in both training (P=0.001) and test (P=0.003) sets. Conclusion: The survival prediction nomogram established based on routine clinical indicators of MPM patients provides a reliable tool for prognostic prediction and risk stratification.
