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.

Objective To explore the feasibility and safety of fastest recovery after surgery(FRAS)in laparoscopic surgery of gastrointestinal tumors.Methods The clinical data of patients undergoing laparoscopic surgery for gastrointestinal tumors under FRAS and enhanced recovery after surgery(ERAS)from Jan.2023 to May 2024 were collected,and perioperative safety and medical cost were analyzed.Results A total of 87 patients were enrolled,including 43 in the FRAS group and 44 in the ERAS group.Compared with the ERAS group,the FRAS group had significantly shorter surgical time(3.0[2.5,3.5]h vs 3.0[2.5,4.0]h),first postoperative movement time([2.85±4.29]h vs[20.18±6.13]h),first postoperative oral feeding time(2.0[2.0,3.0]h vs 24.0[15.0,48.0]h),postoperative hospital stay(24.0[20.0,40.0]h vs 192.0[150.0,216.0]h),lower hospitalization costs(50 515.61[46 650.44,56 827.12]yuan vs 65 555.09[58 683.21,86 239.02]yuan),and lower medication costs(2 671.09[2 063.31,3 127.09]yuan vs 7 326.90[5 104.66,10 674.26]yuan)(all P＜0.05).Conclusion It is safe and feasible to use FRAS during the perioperative period of laparoscopic radical gastrectomy for gastrointestinal tumors,and FRAS can also reduce the costs of hospitalization and medications.

[摘 要] 目的：研究芳香烃受体（AHR）在乳腺癌中的表达及其对乳腺癌细胞增殖、凋亡和药物敏感性的调控机制。方法：通过GEPIA数据库数据分析乳腺癌组织及癌旁组织中AHR的表达水平，探讨其与患者生存期的关联。利用基因敲低和过表达技术构建AHR表达变化的乳腺癌细胞，采用CCK-8实验、细胞计数和流式细胞分析等方法评估AHR对细胞增殖、凋亡和药物敏感性的影响，通过免疫印迹法验证相关分子机制。此外，利用AHR激动剂6-甲酰基吲哚并[3,2-B]咔唑（FICZ）研究外源性激活AHR对乳腺癌细胞多柔比星（DOX）敏感性的影响。结果：GEPIA数据库数据分析结果显示，乳腺癌组织中AHR呈明显低表达（P < 0.05）；对155例乳腺癌患者的生存期进行统计分析也显示AHR低表达与不良预后呈正相关（P < 0.05）。敲低AHR促进细胞增殖（P < 0.05），过表达则能抑制其增殖（P < 0.05）并促进其凋亡（P < 0.05）。外源激活AHR能增强乳腺癌细胞对DOX的敏感性（P < 0.05）。AHR可与MYC基因启动子结合，抑制MYC表达（P < 0.05），从而影响乳腺癌的进展。结论：AHR在乳腺癌中通过调控MYC表达影响细胞增殖和凋亡，外源激活AHR可能成为提高乳腺癌细胞对DOX敏感性的治疗策略。

ObjectiveTo observe the effect of tendon clearing combined with Zizhu ointment on the serum levels of nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） inflammasomes， interleukin （IL）-1β， and IL-18 in the treatment of non-ischemic diabetic foot ulcers. MethodA total of 106 patients with non-defective diabetic foot ulcers who attended the outpatient clinic and wards of the Vascular Surgery Department of Shuguang Hospital affiliated to Shanghai University of Traditional Chinese Medicine from March 2023 to March 2024 were selected. The patients with non-ischemic diabetic foot ulcers who met the inclusion criteria were assigned with the random number table method into an observation group and a control group， with 53 patients in each group. Patients in both groups received basic treatment. The local ulcers in the observation group received tendon clearing combined with Zizhu ointment， while those in the control group received conventional debridement combined with topical solution of bovine basic fibroblast growth factor. The serum NLRP3， IL-1β， and IL-18 levels， ulcer area， traditional Chinese medicine （TCM） symptom scores， visual analogue scale （VAS） score， and DMIST score were measured and recorded in the two groups before and after treatment. The ulcer healing rate and incidence of adverse reactions were compared between the two groups. ResultThe observation group had higher ulcer healing rate than the control group （P<0.01）. After treatment， both groups showed lowered serum NLRP3， IL-1β， and IL-18 levels， reduced ulcer area， and declined TCM symptom score， VAS score， and DMIST score （P<0.01）. Moreover， these indicators were lower in the observation group than in the control group （P<0.05， P<0.01）. Neither group showed significant changes in the liver and kidney function indicators after treatment. Significant adverse reactions occurred in neither group during the treatment course. ConclusionTendon clearance combined with Zizhu ointment was effective and safe in treating non-ischemic diabetic foot ulcers. It may exert the therapeutic effect by reducing the inflammation of the local ulcers.

Objective:To investigate the current status and influencing factors of care preparedness in primary caregivers of children with acute leukemia, so as to provide theoretical basis for targeted nursing intervention plans in the future.Methods:A total of 160 primary caregivers of children with acute leukemia in Hematology Hospital of the Chinese Academy of Medical Sciences recruited by convenient sampling were investigated by the general data questionnaire, the Preparedness for Caregiving Scale, the Herth Hope Index, the Family Caregiver Task Inventory and the Mishel Uncertainty in Illness Scale-Family Member Form. Descriptive analysis, Mann-Whitney U test, Kruskal-Wallis H test, Spearman rank correlation and multiple stepwise liner regression were used for statistical analysis. Results:One hundred and fifty-nine questionnaires were effectively collected, including 13 males and 146 females, aged (34.61 ± 8.60) years old. The total score of care preparedness, hope, uncertainty in illness, care ability for caregivers were (26.47 ± 7.53), (37.72 ± 4.11), (61.96 ± 17.02), (15.06 ± 12.94) points. The total score of care preparedness for caregivers was negatively correlated with the score of uncertainty in illness( r=-0.300, P<0.05), and positively correlated with the hope and care ability of main caregivers ( r=0.166, 0.254, both P<0.05). Caregivers′ uncertainty in illness, caregiver gender, availability of other caregivers, caregivers′ hope entered the multiple stepwise regression equation, which could explain 20.4% of the total variation of resilience. Conclusions:The preparation of the primary caregivers for children with acute leukemia is at a medium level. The primary caregivers who are male, who have insufficient knowledge of the disease, who have no co-caregivers, and who have low hope level should be focused on in clinical practice. Pertinent measures should be taken to improve care preparedness and care quality.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To investigate the value of the combined ultrasound imaging radiomics model for predicting progression-free survival in endocrine therapy for prostate cancer.Methods:A total of 283 prostate cancer patients who received endocrine treatment at the Inner Mongolia Autonomous Region People′s Hospital and the First Hospital of Hohhot from July 2018 to January 2023 were retrospectively collected, of which 198 patients from the Inner Mongolia Autonomous Region People′s Hospital were randomly divided into the training set and the validation set according to the ratio of 7∶3, and 85 patients from the First Hospital of Hohhot served as an independent external test set. They were classified into a progression group and a non-progression group based on whether the patients progressed to desmoplasia-resistant prostate cancer 18 months after the start of endocrine treatment.Based on the two-dimensional ultrasound images, the imaging radiomics features were extracted and the imaging radiomics score (Rad-score) were constructed, the immunopathology and other clinical data were analysed, and three prediction models were constructed using logistic regression: the clinical model, the ultrasonography model, and the ultrasonography-clinical combined model, respectively. The predictive efficacy and clinical utility of the models were assessed by the ROC curves and clinical decision curves.Results:Five ultrasonographic features were included in the ultrasound model; the prostate-specific antigen nadir, the neutrophil-to-lymphocyte ratio before treatment, and the expression level of tumour proliferating cell nuclear antigen 67 (Ki-67) were incorporated into the clinical model; and the Rad score computed from the output of the ultrasound model for the screening features, together with the prostate-specific antigen nadir (PSA nadir), the neutrophil to lymphocyte ratio (NLR) before treatment, and the expression level of Ki-67 were used to construct the ultrasound-clinical joint model. The joint model achieved the highest predictive performance in both the training and validation sets of the three groups of models, with the area under the curve of 0.85 and 0.84, and the clinical decision curve showed good clinical benefit.Conclusions:The combined ultrasound-clinical model constructed in this study based on two-dimensional ultrasound images of prostate cancer before endocrine therapy can predict progression-free survival of endocrine therapy for prostate cancer more accurately.

OBJECTIVE: To investigate the effect of hyperbaric oxygen (HBO) on paroxysmal sympathetic hyperexcitation (PSH) after brain injury. METHODS: A multicenter retrospective study was conducted. Fifty-six patients with PSH who received HBO treatment from four hospitals in Henan Province from January 2021 to September 2023 were selected as the HBO group, and 36 patients with PSH who did not receive HBO treatment from Zhengzhou People's Hospital from May 2018 to December 2020 were selected as the control group. PSH assessment measure (PSH-AM) score [clinical feature scale (CFS) score+diagnostic likelihood tool (DLT) score] and Glasgow coma scale (GCS) were compared before and after HBO treatment, and between HBO group and control group to evaluate the effect of HBO treatment on prognosis of PSH patients. RESULTS: There were no statistically significant differences in age, gender, PSH etiology, GCS score, time from onset to occurrence of PSH, CFS score, CFS+DLT score and frequency of PSH episodes between the two groups, indicating comparability. The duration of HBO treatment ranged from 3 to 11 days for 56 patients receiving HBO treatment, and the duration of HBO treatment ranged from 3 to 5 courses. Compared with before treatment, after HBO treatment, PSH symptoms in HBO patients were significantly relieved (body temperature increase: 14.29% vs. 64.29%, heart rate increase: 25.00% vs. 98.21%, shortness of breath: 14.29% vs. 76.79%, blood pressure increase: 8.93% vs. 85.71%, sweating: 10.71% vs. 85.71%, muscle tone increased: 19.64% vs. 75.00%, all P < 0.05), CFS+DLT score decreased significantly (16.90±4.81 vs. 22.12±3.12, P < 0.01), GCS score improved (12.31±5.34 vs. 5.95±2.18, P < 0.01). After 30 days of hospitalization, compared with the control group, PSH symptoms in the HBO group were improved (body temperature increase: 14.29% vs. 19.44%, heart rate increase: 19.64% vs. 25.00%, shortness of breath: 10.71% vs. 27.78%, blood pressure increase: 7.14% vs. 22.22%, sweating: 8.93% vs. 25.00%, muscle tone increased: 19.64% vs. 38.89%, all P < 0.05 except body temperature increase), CFS+DLT score decreased (16.90±3.81 vs. 19.98±4.89, P < 0.05), GCS score increased (14.12±4.12 vs. 12.31±4.14, P < 0.01), the length of intensive care unit (ICU) stay was shortened (days: 18.01±5.67 vs. 24.93±8.33, P < 0.01). CONCLUSIONS HBO treatment can significantly relieve the symptoms of patients with PSH after brain injury and provide a new idea for the treatment of PSH patients.

ObjectiveTo prepare matrine lipid-based cubic liquid crystalline nanoparticle （MAT-LLCN） gels and investigate its in vitro release and transdermal absorption behavior. MethodTaking entrapment efficiency as the index， the optimal formulation of MAT-LLCN was screened by extreme vertex mixture method based on the optimal ratio of glycerol monooleate （GMO） to poloxamer 407 （P407）， and its drug loading was investigated. MAT-LLCN gels was prepared by mixing MAT-LLCN with pre-swelled carbomer 940 as the gel matrix. The structure of MAT-lipid-based cubic liquid crystalline （LLC） was characterized by polarized light microscopy （PLM） and small angle X-ray scattering （SAXS）. The in vitro release and transdermal absorption properties of MAT-LLCN gels and MAT ordinary gels were compared by modified Franz diffusion cell method， skin structure changes caused by them were observed by hematoxylin-eosin （HE） staining. ResultThe optimal formulation of MAT-LLCN gels was 5.5% of GMO-P407 （9∶1）， 1%-6% of MAT， 0.6% of carbomer 940， adding water to sufficient amount. The prepared MAT-LLC was confirmed as body-centered （Im3m） LLC. The in vitro release behavior of MAT-LLCN gels was in accordance with the Weibull equation （R²=0.954 0）， and the release mechanism was the Fick diffusion. In vitro transdermal test showed that all the parameters of MAT-LLCN gels were higher than those of MAT ordinary gels （P<0.05）， including cumulative release rate， steady-state release rate and the amount of drug retention in skin. HE staining results showed that MAT-LLCN gels could loose the cellular arrangement of skin stratum corneum， and maintain the stability of the cell structure of the dermis. ConclusionThe prepared MAT-LLCN gels can accelerate the transdermal drug transport and form drug storage in the dermis by rapidly opening the skin stratum corneum barrier， suggesting that LLC has good application prospects in the field of transdermal drug delivery.
