ObjectiveTo explore the effect and mechanism of Jianpi Xiaoai prescription （JPXA） in ameliorating the 5-fluorouracil （5-FU） resistance of colon cancer. MethodsA HCT116/5-FU resistant cell line was established. Different concentrations （10%， 15%， 20%） of JPXA-containing serum and drug-free serum were used for intervention， and 10% fetal bovine serum （10% FBS）， fibroblast growth factor receptor （FGFR） inhibitor （AZD4547）， and recombinant fibroblast growth factor 2 （FGF2） were set as the control groups. Sensitive HCT116 cells were used in the FGF2 group， while HCT116/5-FU cells were used in other groups. Drug resistance， the level of FGF2 in the cell culture medium， the mRNA level of FGF2 in cells， and the protein levels of FGF2/FGFR and phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） were determined. The drug-resistant cells were transplanted into the axilla of nude mice to establish a tumor model. The modeled mice were allocated into model， JPXA （15 g·kg^-1）， 5-FU （0.02 g·kg^-1）， JPXA+5-FU （15 g·kg^-1+0.02 g·kg^-1）， AZD4547 （0.012 5 g·kg^-1）， and AZD4547+5-FU （0.012 5 g·kg^-1+0.02 g·kg^-1） groups. The tumor growth and the protein levels of FGF/FGFR and PI3K/Akt in each group were observed. ResultsThe survival rate of HCT116/5-FU cells decreased in all the JPXA groups with different concentrations. The cell survival rate was decreased most obviously in the 20% JPXA group. The level of FGF2 in the cell culture medium and the mRNA level of FGF2 in cells of each JXPA group decreased， and the decrease was the most significant in the 20% group （P<0.01）. HCT116/5-FU cells showed up-regulated protein levels of FGF2 and phosphorylated fibroblast growth factor receptor 1 （p-FGFR1）， but down-regulated protein level of FGFR1 （P<0.01）. JPXA down-regulated the expression of FGF2 and p-FGFR1 and up-regulated the expression of FGFR1 （P<0.05）. In addition， JPXA down-regulated the expression levels of phosphorylated protein kinase B （p-Akt） and phosphorylated mammalian target of rapamycin （p-mTOR）， while up-regulating the expression levels of Akt and Bcl-2-asociated death promoter （Bad） （P<0.05）. Animal experiments showed that the JPXA combined with 5-FU significantly inhibited the growth of drug-resistant tumors， reduced the protein levels of FGF2， p-FGFR1， phosphorylated phosphatidylinositol-3-kinase （p-PI3K）， p-Akt， and p-mTOR， and increased the expression of Bad. It indicated that JPXA can inhibit the FGF2/FGFR1 signaling in colon cancer and regulate PI3K/Akt and downstream signaling pathways. ConclusionJPXA can ameliorate the chemotherapy resistance of colon cancer through down-regulating FGF2 expression and inhibiting the activation of the PI3K/Akt signaling pathway.

BACKGROUND: Children's respiratory health demonstrates particular sensitivity to air pollution. Existing evidence investigating the association between short-term ozone (O₃) exposure and childhood pneumonia remains insufficient and inconsistent, especially in low- and middle-income countries (LMICs). METHOD: To provide more reliable and persuasive evidence, we implemented a multi-city, time-stratified case-crossover design with a large sample size, using data from seven representative children's hospitals across major geographical regions in China. To avoid the impact of the COVID-19 pandemic, individual-level medical records of inpatient children under 6 years of age diagnosed with pneumonia during 2016-2019 were collected. Conditional logistic regression models were fitted for each city, and city-specific estimates were pooled through a meta-analysis using a random-effects model. RESULTS: In total, the study included 137,470 pediatric pneumonia hospital admissions. The highest pooled estimate for O₃ occurred at lag0-1, with a 10 µg/m³ increase in O₃ associated with a 1.57% (95% CI: 0.67%-2.48%) higher risk of pediatric pneumonia hospital admissions. Stratified analyses indicated that the effects of O₃ were robust across different sexes, age groups, and admission seasons. We also observed a statistically significant increase in risk associated with O₃ concentrations exceeding the World Health Organization Air Quality Guidelines (WHO-AQGs). CONCLUSIONS This study revealed a significant positive association between O₃ and pediatric pneumonia hospital admissions. Our findings substantially strengthen the evidence base for the adverse health impacts of O₃, underscoring the importance of O₃ pollution control and management in reducing the public health burden of pediatric pneumonia.

Objective:To explore the effects of different surgical methods on the treatment outcomes and prog-nosis in patients with caesarean section scar pregnancy(CSP).Methods:A total of 90 patients with type n or ⅢCSP admitted to Department of Obstetrics and Gynecology,Affiliated Hospital of Jinggangshan University be-tween February 1,2021 and February 1,2022 were selected as the study subjects.They were enrolled in order of inclusion,exclusion criteria,and admission treatment time.According to different treatment methods,they were di-vided into group A(30 cases),group B(30 cases)and group C(30 cases).The group A underwent laparoscopic uterine artery ligation(UAL)+focus excision and repair of scar pregnancy(FER)+uterine cicatricial repair(UCR),group B underwent uterine artery embolization(UAE)+hysteroscopic FER under ultrasonic monitoring,and group C underwent laparoscopic FER+UCR.The intraoperative and postoperative conditions,as well as the incidence of recurrent CSP(RCSP)rate and repregnancy rate during follow-up in the three groups were com-pared.Results:① The intraoperative blood loss,postoperative uterine drainage volume and postoperative VAS score in groups A and B were lower than those in group C,while the operation time and hospitalization cost were higher than those in group C(P＜0.05).The operation time and hospitalization cost in group A were lower than those in group B(P＜0.05).②The postoperative vaginal hemostasis time,menstrual recovery time and recovery time of serum β-human chorionic gonadotropin(β-HCG)in groups A and B were shorter than those in group C(P＜0.05).③There was no statistically significant difference in the incidence of postoperative complications such as adhesion,infection,severe bleeding,and lower abdominal pain among the three groups(P＞0.05).④The mean follow-up time after surgery was(17.60±5.61)months,and the incidence of RCSP in group A and group C was lower than that in group B(P＜0.05).The rate of repregnancy in group A,group B and group C was 82.14％(23/28),77.78％(21/27)and 81.48％(22/27),respectively,and there was no significant difference in the rate of repregnancy among the three groups(P＞0.05).Conclusions:Laparoscopic UAL+FER+UCR and UAE+ultrasound monitoring hysteroscopic FER can reduce intraoperative bleeding and promote postoperative re-covery,but the surgery time is prolonged and hospitalization costs are higher;After using UCR treatment,the inci-dence of RCSP is lower.Clinical evaluation should be based on the specific condition,economic conditions,and need to preserve fertility of type Ⅱ and Ⅲ CSP patients,and personalized treatment plans should be developed.
