Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

ObjectiveTo analyze the processing mechanism underlying the enhanced effect of invigorating spleen and stopping diarrhea of soil-fried Atractylodis Macrocephalae Rhizoma（AMR） by analyzing the changes of microstructure， chemical composition and anti-ulcerative colitis（UC） activity before and after soil stir-frying. MethodsThe microstructure and elemental composition of AMR before and after soil stir-frying were analyzed by scanning electron microscopy-energy dispersive spectroscopy（SEM-EDS）， to investigate the differences in microstructure and the underlying causes. Ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS） coupled with UNIFI 1.9.2 natural product analysis platform were used to analyze and identify the chemical constituents in raw and soil-fried products， and multivariate statistical methods including principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were used to explore the differences and sources of chemical constituents between them. A dextran sulfate sodium（DSS）-induced UC mouse model was established. The method of disease activity index（DAI） was used to evaluate the severity of intestinal inflammation. Hematoxylin-eosin（HE） staining was used to observe the pathological changes of colon tissue， enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of inflammatory factors， Real-time quantitative polymerase chain reaction（Real-time PCR） and Western blot were used to analyze the expressions of key genes and proteins involved in the intestinal mucosal barrier. The 16S rRNA sequencing was used to evaluate the diversity of intestinal flora， headspace gas chromatography-mass spectrometry（HS-GC-MS） was used to explore the levels of short-chain fatty acids（SCFAs） in feces. Base on the above findings， this paper investigated the effects of raw and soil-fried AMR on the biological， chemical， mechanical and immune barriers of model animals， and the differences in pharmacological effects and underlying mechanisms from the perspective of regulating the intestinal mucosal barrier in UC mice. ResultsSEM observation revealed numerous hearth soil particles on the surface of soil-fried AMR， accompanied by bubble-like bulges. At the same time， there were many cracks and folds on the surface of the hearth soil. EDS analysis revealed that the contents of Si， Al， Mg and Ca in soil-fried AMR were significantly higher than those of raw products， and these elements constituted the primary components of hearth soil. UPLC-Q-TOF-MS combined with database comparison was used to identify the chemical constituents of raw and soil-fried AMR. In positive ion mode， a total of 132 components were identified， primarily comprising three categories of terpenoids， polyphenols and amino acids. In negative ion mode， a total of 40 components were identified， primarily polyphenolic and glycoside compounds. Among them， the contents of sesquiterpenes and polyphenolic acids were changed significantly before and after processing. Soil-fried AMR could reduce the DAI score of UC mice， alleviate the shortening of colon length， reduce the levels of pro-inflammatory factors such as interleukin（IL）-17， IL-18， γ-interferon（IFN-γ） and tumor necrosis factor（TNF）-α in serum， increase the levels of anti-inflammatory factors such as secretory immunoglobulin A（sIgA）， IL-10， IL-4 and transforming growth factor-β（TGF-β） in serum， increase the expressions of key genes and proteins of intestinal mucosal barrier such as tight junction protein-1（ZO-1）， Occludin， Claudin-1 and mucin 2（MUC2） in colonic mucosa， and improve the disorders of intestinal flora diversity and the levels of SCFAs（P<0.05， P<0.01）. The raw and stir-fried products of AMR also exhibited the aforementioned effects， but they were weaker than the soil-fried products. Additionally， the auxiliary material hearth soil also had a certain pharmacodynamic effect. ConclusionSoil-fried AMR can enhance the protective effect on intestinal mucosal barrier in UC mice. These changes or heating-induced alterations in the microscopic structure and chemical composition of AMR may be attributed to the dual effects of adsorption of hearth soil.

OBJECTIVE: The study aim was to investigate the effects of exposure to multiple environmental organic pollutants on cardiopulmonary health with a focus on the potential mediating role of oxidative stress. METHODS: A repeated-measures randomized crossover study involving healthy college students in Beijing was conducted. Biological samples, including morning urine and venous blood, were collected to measure concentrations of 29 typical organic pollutants, including hydroxy polycyclic aromatic hydrocarbons (OH-PAHs), bisphenol A and its substitutes, phthalates and their metabolites, parabens, and five biomarkers of oxidative stress. Health assessments included blood pressure measurements and lung function indicators. RESULTS: Urinary concentrations of 2-hydroxyphenanthrene (2-OH-PHE) ( β = 4.35% [95% confidence interval ( CI): 0.85%, 7.97%]), 3-hydroxyphenanthrene ( β = 3.44% [95% CI: 0.19%, 6.79%]), and 4-hydroxyphenanthrene (4-OH-PHE) ( β = 5.78% [95% CI: 1.27%, 10.5%]) were significantly and positively associated with systolic blood pressure. Exposures to 1-hydroxypyrene (1-OH-PYR) ( β = 3.05% [95% CI: -4.66%, -1.41%]), 2-OH-PHE ( β = 2.68% [95% CI: -4%, -1.34%]), and 4-OH-PHE ( β = 3% [95% CI: -4.68%, -1.29%]) were negatively associated with the ratio of forced expiratory volume in the first second to forced vital capacity. These findings highlight the adverse effects of exposure to multiple pollutants on cardiopulmonary health. Biomarkers of oxidative stress, including 8-hydroxy-2'-deoxyguanosine and extracellular superoxide dismutase, mediated the effects of multiple OH-PAHs on blood pressure and lung function. CONCLUSION Exposure to multiple organic pollutants can adversely affect cardiopulmonary health. Oxidative stress is a key mediator of the effects of OH-PAHs on blood pressure and lung function.

Objective To evaluate the diagnostic value of ultrasound in chronic appendicitis. Methods A retrospective analysis was conducted on the ultrasound imaging features of the appendixes in 68 patients with chronic appendicitis (chronic appendicitis group) confirmed by pathological results at the Affiliated Hospital of Inner Mongolia Medical University from January 2023 to December 2024,as well as 85 healthy volunteers (normal appendix group) of different ages with no history of abdominal pain during the same period.Multivariate Logistic regression was employed to investigate the sensitivity and specificity of different variables in diagnosing chronic appendicitis. Results The chronic appendicitis group had higher appendix diameter (Z=-8.47,P<0.001),unilateral wall thickness (Z=-7.16,P<0.001),and submucosal thickness (Z=-9.73,P<0.001) than the normal appendix group.Appendix diameter (OR=3.11,95%CI=1.37-7.02,P=0.006) and submucosal thickness (OR=5 492.73,95%CI=89.53-336 984.13,P<0.001) were identified as independent factors for diagnosing chronic appendicitis,while gender,age,unilateral wall thickness,and intraluminal conditions had no significant impact on the diagnosis of chronic appendicitis (all P>0.05).When appendix diameter combined with submucosal thickness was used as a joint diagnostic indicator,the model demonstrated the best performance,with the sensitivity of 92.65%,the specificity of 97.65%,and the accuracy increasing to 95.42%. Conclusion The combined use of appendix diameter and submucosal thickness can significantly improve the accuracy,specificity,and reliability of ultrasound in diagnosing chronic appendicitis.

Objective To explore the effect of management model of clinical pharmacists participating in multidisciplinary collaborative diagnosis and treatment(MDT)for new anti-tumor drugs in the national medical insurance drug negotiation(hereinafter referred to as"national negotiation"),including efficacy,safe-ty,economy and rationality.Methods The medical records of 326 cases using novel anti-tumor drugs by na-tional negotiation and conforming to the including and excluding standards in this hospital from July 2018 to June 2023 were retrospectively analyzed.The patients were divided into the MDT group(n=122)and non-MDT group(n=204).The patients diagnosed as non-small cell lung cancer(NSCLC)in the two groups were extracted and defined as the MDT-NSCLC subgroup(n=41)and non-MDT-NSCLC subgroup(n=77).The progression-free survival(PFS),overall survival(OS),disease control rate(DCR)and the indexes such as survival quality and medical quality control were compared between the groups.Results The median PFS in the two groups was 12.7 months and 8.0 months,the median OS was 75.2 months and 56.3 months,DCR was 96.72％and 81.86％respectively,and the differences were statistically significant(P＜0.05).The COX multivariate regression analysis indicated that the HR value of clinical pharmacists participating in MDT was higher than the other influencing factors.The median PFS time in the MDT-NSCLC subgroup and non-MDT-NSCLC subgroup was 10.5 months and 6.7 months,DCR was 97.30％and 75.64％respectively,and the differences were statistically significant(P＜0.05),the median OS time was 55.1 months and 40.3 months respectively,and the difference was statistically significant(P＞0.05).The COX multivariate regression anal-ysis indicated that the HR value with clinical pharmacists participating in MDT was higher than the other in-fluencing factors;The adverse reaction occurrence rate in the MDT group and non-MDT group was 45.9％and 58.3％respectively,and the difference was statistically significant(P＜0.05).The KPS score after treatment in the MDT group was higher than that in the non-MDT group,and the difference was statistically significant;in the aspect of medical quality control,the average drug proportion in the MDT group and non-MDT group was 63.93％and 64.54％respectively,the rational drug rate of comments on prescription was 98.36％and 88.73％respectively,the patient satisfaction average value was 90.69 points and 87.36 points respectively and the differences were statistically significant(P＜0.05).Conclusion Clinical pharmacists participating in MDT related to novel anti-tumor drugs by national negotiation is beneficial to improve the therapeutic effects,living quality and patient satisfaction,also benefit to management and control of off-label drug use and medical quality control indexes.

Objective To compare the application effects of plankton multiplex polymerase chain reac-tion-capillary electrophoresis(PCR-CE),SYBR Green Ⅰ real-time quantitative PCR(qPCR)and microwave digestion-vacuum filtration-automated scanning electron microscopy(MD-VF-Auto SEM)in the diagnosis of drowning.Methods Lung,liver and kidney tissues from 212 drowned corpses and 30 non-drowned corpses were examined respectively by the three drowning-related plankton testing methods,and the detection rates of plankton in each tissue by three methods were compared.Results In drowned corpses,the total detection rates of PCR-CE,qPCR,and MD-VF-Auto SEM were 93.9%,96.2%,and 95.3%,respectively,with no statistically significant difference(P>0.05).The detection rate of lung tissue by MD-VF-Auto SEM(100%)was higher than those of PCR-CE and qPCR(P<0.05),and there was no significant difference in the detection rates of the three methods in liver or kidney tissues(P>0.05).In non-drowning corpses,a small number of diatoms(less than 10 cells/10 g)were detected by MD-VF-Auto SEM method,only in liver and kidney tissues,while the other two methods yielded negative results for all tissues.Conclusion All three methods have good efficacy in the examination of drowned corpses.The MD-VF-Auto SEM method directly observes diatom morpho-logical characteristics through scanning electron microscopy,and the qualitative and quantitative analy-ses are intuitive and accurate.It has great advantages in the examination of difficult degradation samples.The PCR-CE method and qPCR method have a low sample demand(0.5 g),are easy to operate and have short detection time(4-7 h).They are easy to be applied in the grassroots depart-ments and are suitable for the rapid determination of drowned corpses in routin cases.The combina-tion of the two DNA methods with the MD-VF-Auto SEM method can increase the detection rate of plankton,ensuring the reliability of examination results.This combined use is of significant importance in the application of drowning diagnosis.
