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.

Background Pyrethroid pesticides (PYRs) can cross the placental barrier to cause intrauterine fetal exposure, which may lead to developmental immunotoxicity (DIT). However, the specific effect of maternal PYR exposure during pregnancy on the cellular immune function of 1-year-old children remains unclear. Objective To explore the effect of PYRs exposure throughout the entire pregnancy on peripheral blood lymphocytes in 1-year-old children and potential sensitive window period of PYRs exposure. Methods A birth cohort was established by enrolling pregnant women in their first trimester and following them and their infants until one year of age. Ultra-high performance liquid chromatography-tandem mass spectrometry was used to detect the levels of PYRs metabolites, including 3-phenoxybenzoic acid (3PBA), 4-fluoro-3-phenoxybenzoic acid (4F3PBA), and cis-3-(2,2-dichlorovinyl)-2,2- dimethylcyclopropane carboxylic acid (cis-DBCA), in the urine of pregnant women during the first trimester (gestational weeks 6-12), the second trimester (gestational weeks 21-24), and the third trimester (gestational weeks 33-36). Peripheral blood leukocyte and lymphocyte counts were measured in children at 12 months of age using the Coulter principle combined with flow cytometry. Exposure levels of PYRs metabolites in each trimester were divided into low, moderate, and high exposure groups based on the 25th (P₂₅) and 75th (P₇₅) percentiles. Meanwhile, participants were classified as having repeated high or low exposure if their metabolite levels were > P₇₅ or <P₂₅ in at least two trimesters, respectively, while all others were categorized as having repeated moderate exposure. Generalized linear models were used to analyze the associations between trimester-specific and repeated PYRs metabolite exposure levels and the peripheral blood white blood cell (WBC) and lymphocyte counts in children aged 1 year. Results A total of 336 mother-child pairs were included in this study. For the pregnant women, the total detection rates of maternal urinary 3PBA, 4F3PBA, and cis-DBCA across the three trimesters of pregnancy were 80.5%, 100.0%, and 81.3%, respectively; and median creatinine-corrected concentrations were 0.24, 0.36, and 0.42 μg·g⁻¹, respectively. In children aged 1 year, the mean WBC and lymphocyte counts in peripheral blood were (8.9±2.0)×10⁹·L⁻¹ and (5.7±1.6)×10⁹·L⁻¹, respectively. The results of the generalized linear model analysis indicated that compared to the low exposure group, the high cis-DBCA exposure group during the third trimester of pregnancy had significantly lower peripheral blood WBC count (β=−0.87, 95%CI: −1.51, −0.23) and lymphocyte count (β=−0.64, 95%CI: −1.15, −0.13); and the repeated high-exposure group of cis-DBCA had significantly lower peripheral blood WBC count (β=−1.34, 95%CI: −2.34, −0.34) and lymphocyte count (β=−0.80, 95%CI: −1.60, −0.01) than the repeated low exposure group. Similarly, the repeated moderate-exposure group of cis-DBCA had a significantly lower peripheral blood WBC count (β=−0.83, 95%CI: −1.59, −0.07) than the repeated low exposure group. Conclusion High maternal exposure to PYRs with cis-DBCA as the major metabolite exposure is associated with decreased peripheral leukocyte and lymphocyte counts in children aged 1 year, and repeated high-level exposure throughout gestation appears to exacerbate DIT in offspring. The third trimester of pregnancy maybe a sensitive window for children's DIT induced by exposure to PYRs during pregnancy.

Objective To investigate the safety, economic benefits and psychological effects of day breast conserving surgery for breast cancer. Methods The demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from June 2021 to June 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.

Objective:To explore the surgical efficacy of cervical cerclage with cervical length (CL) <10 mm and emergency cerclage.Methods:From January 2013 to June 2022, a total of 98 singleton pregnant women who underwent ultrasound-indicated cervical cerclage because of CL<10 mm in the second trimester and underwent emergency cervical cerclage because of cervical dilation found by physical examination in Peking University First Hospital were enrolled. The differences in clinical data between the <34 weeks delivery group (25 cases) and the ≥34 weeks delivery group (73 cases) were compared. Meanwhile, according to different cervical status, they were divided into CL<10 mm group (43 cases) and cervical dilatation group (55 cases), and the cervical dilatation group was further divided into cervical dilatation <4 cm group and cervical dilatation ≥4 cm group. The clinical data and pregnancy outcomes of pregnant women with different cervical status were compared.Results:(1) There were significant differences in the proportion of preoperative CL<10 mm and the degree of preoperative cervical dilation between the <34 weeks delivery group and the ≥34 weeks delivery group (all P<0.05). (2) After cervical cerclage, compared with women in the cervical dilatation group, the prolonged gestational age in the CL<10 mm group was longer [(10.5±4.6) vs (14.3±3.4) weeks], the gestational age at delivery was later (median: 35.7 vs 38.0 weeks), the preterm birth rates before 37 and 34 weeks were lower, the late abortion rate was lower [9% (5/55) vs 0 (0/43)], and the newborn birth weight was higher, the differences were statistically significant (all P<0.05). (3) Compared with the cervical dilation ≥4 cm group, the prolonged gestational age of the cervical dilatation <4 cm group was longer [(7.5±5.3) vs (11.1±4.2) weeks], the gestational age at delivery was later (median: 29.2 vs 36.0 weeks), and the birth weight of the newborn was higher (all P<0.05). The late abortion rate of cervical dilatation <4 cm group was lower than that of cervical dilatation ≥4 cm group [7% (3/45) vs 2/10; P=0.220]. Conclusions:Timely cervical cerclage in individuals with CL<10 mm could reduce preterm birth rate before 34 weeks gestation, and the pregnancy outcome is better than that of individuals with cervical dilation. Moreover, the pregnancy outcome of cervical cerclage in women with cervical dilation <4 cm is significantly better than that in women with cervical dilatation ≥4 cm.

Global public health faces substantial challenges from malignant tumors and infectious diseases. Vaccination provides an approach for treating and preventing these diseases. Oral vaccinations are particularly advantageous in disease treatment and prevention due to their non-invasive nature, high patient compliance, convenience, cost-effectiveness, and capacity to stimulate comprehensive and adaptive immune responses. However, the overwhelming majority of oral vaccines remain in experimental development, struggling with clinical and commercial translation due to their suboptimal efficacy. Thus, enhancing scientists' understanding of the interaction between vaccines and gastrointestinal immune system, creating antigen delivery systems suitable for the gut mucosal environment, developing more potent antigenic epitopes, and using personalized combination therapies are critical for advancing the next generation of oral vaccines. This article explores the fundamental principles and applications of current oral anti-tumor and anti-infective vaccines and discusses considerations necessary for designing future oral vaccines.

Objective:To construct a risk assessment system for measles transmission in Henan Province and scientifically evaluate the risk levels of measles transmission in each city in Henan Province.Methods:The modified Delphi method was used to conduct two rounds of expert consultations to construct a risk assessment system for measles transmission. Data from all 191 cities, counties and districts in Henan Province were collected. The internal consistency (Cronbach′s α), content validity (content validity index, CVI) and structural validity (factor analysis) of the indicator system were evaluated to optimize the assessment framework. The indicator assignment method was adopted, and the comprehensive risk scores were obtained by adding the scores according to different weights. Results:Both rounds of consultation witnessed a 100% participation rate among all experts. The authority coefficients of experts in the two rounds were 0.920 and 0.925, and concordance coefficients were 0.201 ( χ 2=161.11, P<0.001) and 0.210 ( χ 2=163.80, P<0.001). The constructed assessment system comprised four dimensions—population immunity levels, surveillance quality, importation risk, and technical reserve of emergency response capacities—with a total of 30 indicators. Reliability analysis of the assessment system showed an overall Cronbach′s α of 0.741. Validity analysis revealed that all content validity indices reached 1.000, with principal factors cumulatively accounting for 67.625% of the variance, and all factor loadings exceeded 0.400. The measles transmission risk assessment in Henan Province using this assessment system identified Zhengzhou (92), Xinxiang (91), Xinyang (89), and Pingdingshan (73) as high-risk regions. Conclusion:The risk assessment system developed in this study demonstrates good reliability and validity, effectively reflecting measles transmission risks across Henan Province. The findings highlight the need to strengthen surveillance and control measures in high-risk areas, particularly in Zhengzhou.

The construction of an information system for equipment budget management in public hospitals is an important measure to strengthen comprehensive budget management, serving as an important foundation for promoting the development of clinical disciplines and enhancing operational management. Since September 2023, a tertiary public hospital had explored the construction of equipment budget management informatization. This practice had established a supporting budget management information system, which included an equipment demand reserve library and a general use product library, linked performance evaluation indicators, implemented visualizing real-time project progress, and strengthened data governance. A series of measures had been taken to move management to equipment demand research, expand the time window for departments to fill in budget requirements, simplify the department application process, and achieve a closed-loop management of the entire chain of department equipment demand research, budget approval, and execution, ensuring the rationality and accuracy of the budget. By the end of 2024, the budget management information system had covered 87 departments and included 30 000 sets of equipment applications, providing detailed data support and critical management references for demand departments, equipment management departments, and hospital decision-makers, while improving the quality and efficiency of in-hospital equipment management. This practice could provide references for other public hospitals in China to optimize their equipment budget management.

Objective:To explore the application effect of intelligent precision feeding guidance mode in postoperative feeding of children with congenital heart disease, in order to provide a scientific, dynamic and effective feeding management method for postoperative children with congenital heart disease.Methods:A prospective, controlled study design was adopted to select 144 pairs of congenital heart disease patients and their primary caregivers who visited the Pediatric Heart Center of Beijing Anzhen Hospital affiliated to Capital Medical University from March to December 2023 using convenience sampling method. They were randomly divided into a control group and an experimental group, with 72 pairs in each group, using a random number table method. The control group received routine feeding guidance, while the experimental group received intelligent precision feeding guidance mode intervention on the basis of the control group. Compared the infant and child feeding index (ICFI), malnutrition and physical development status, and primary caregiver′s Positive Aspects of Caregiving (PAC) scores between two groups of children with congenital heart disease.Results:Finally, 130 pairs of children and their primary caregivers completed this study, with 64 pairs in the control group and 66 pairs in the experimental group. There were 30 males and 34 females in the control group, with an aged of (11.64 ± 5.03) months; there were 35 males and 31 females in the experimental group, with an aged of (11.03 ± 5.07) months. Among the primary caregivers of the control group, there were 53 mothers and 11 fathers/grandparents/other caregivers; among the main caregivers of the experimental group, there were 62 mothers and 4 fathers/grandparents/other caregivers. The ICFI of the experimental group at 3 and 6 months after surgery were 13.0(10.0, 14.0) and 15.0(13.0, 15.0) points, respectively, which were higher than those of the control group at 11.0(9.0, 13.0) and 12.0(9.0, 14.0) points, and the differences were statistically significant ( Z=8.23, 22.32, both P<0.05). The ICFI qualification rates of the experimental group at 3 and 6 months after surgery were 37.1% (23/62) and 59.3% (35/59), respectively, which were higher than the control group′s 19.7% (12/61) and 31.6% (18/57), and the differences were statistically significant ( χ2=4.59, 8.99, both P<0.05). At 6 months after surgery, the body weight of the experimental group increased was (1.78 ± 0.46) kg, which was higher than that of the control group (1.50 ± 0.52) kg, and the difference was statistically significant ( t=-3.23, P<0.05). In addition, at 6 months after surgery, the incidence of acute malnutrition in the experimental group was 12.1% (8/66), which was lower than that of the control group 25.0% (16/64), and the difference was statistically significant ( χ2=4.36, P<0.05). At 6 months after surgery, the scores of self affirmation, life outlook dimension and the total PAC score of the primary caregiver in the experimental group were (23.45 ± 3.57), (11.97 ± 1.91), and (35.96 ± 4.92) points, respectively, which were higher than those in the control group (22.11 ± 3.40), (11.02 ± 1.90) and (33.13 ± 4.86) points, and the differences were statistically significant ( t=-2.20, -2.86, -2.68, all P<0.05). Conclusions:The use of intelligent precision feeding guidance mode for feeding management of postoperative children with congenital heart disease can effectively improve the positive feelings of caregivers, achieve scientific feeding, increase the ICFI and its qualification rate of children, thereby improving their nutritional status and promoting growth and development.
