Objective: To explore the relationship between snack consumption and depressive symptoms in first year junior high school students with different left behind experiences in Yunnan Province, so as to provide a basis for improving depressive symptoms among first year junior high school students with different left behind experiences. Methods: From October to December 2022,a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County) in Yunnan Province for a questionnaire survey. The Chinese version of Depression Anxiety Stress Scale-21 was applied to assess depressive symptoms in first year junior high school students, and snack consumption was collected by employing food frequency questionnaire. The generalized linear model was used to analyze the association between first year junior high school students snack consumption and depressive symptoms, and the analysis was stratified according to left behind experience. Results: The detection rates of depressive symptoms among firstyear junior high school students with and without left behind experience were 36.25% and 26.91%, respectively. After controlling for confounding variables, the generalized linear model analysis showed that sweet snacks ( β=0.16, 95%CI =0.07-0.25), fast food ( β=0.14, 95%CI =0.04-0.23) and carbonated drinks ( β=0.09, 95%CI =0.01-0.17) of first year junior high school students with left behind experience (all P <0.05). Compared with those without such behavior, the risk of depressive symptoms was higher in consumption of fast food ( β=0.13, 95%CI =0.07-0.18) and carbonated drinks ( β=0.10, 95%CI =0.06-0.15)among first year junior high school students without left behind experience (both P <0.05). Conclusion Snack consumption among first year junior high school students in Yunnan may increase the risk of developing depressive symptoms, while first year junior high school students with left behind experience may have a greater risk of developing depressive symptoms.

OBJECTIVE To investigate the clinical efficacy and mechanism of Gongliuxiao capsule combined with dienogest （DNG） in the treatment of refractory/recurrent endometriosis （EMT）. METHODS A retrospective analysis was conducted on the clinical data of 94 patients with refractory/recurrent EMT admitted to Qingdao TCM Hospital from January 2022 to January 2025. According to different treatment methods， they were divided into a monotherapy group （47 cases， receiving DNG monotherapy） and a combination group （47 cases， receiving Gongliuxiao capsule combined with DNG）. The cl inical efficacy， symptom and sign scores [Visual Analog Scale （VAS） and Pictorial Blood Loss Assessment Chart （PBAC） scores ] ， vascular endothelial function indicators [serum transforming growth factor-β 1 （TGF-β 1 ）， vascular endothelial growth factor （VEGF）， matrix metalloproteinase-2 （MMP-2）， MMP-9， basic fibroblast growth factor （bFGF） ] ， serum pathological factors [carbohydrate antigen 125 （CA125）， CA199， anti-endometrial antibody （EMAb） ] ， and Th1/Th2 drift indicators [interferon-γ （IFN-γ）， interleukin-4 （IL-4） ] were compared between the two groups before and after 6 months of treatment. RESULTS After treatment， the VAS and PBAC scores， serum levels of TGF-β 1 ， VEGF， MMP-2， MMP-9， bFGF， CA125， CA199， EMAb， and IL-4 in both groups were significantly lower than those before treatment， while IFN-γ levels were significantly higher than those before treatment （ P ＜0.05）. Moreover， the magnitude of increase or decrease in the combination group was significantly greater than that in the monotherapy group （ P ＜0.05）. The total effective rate in the combination group was significantly higher than that in the monotherapy group （93.62% vs. 76.60%， P ＜0.05）. CONCLUSIONS The combination of Gongliuxiao capsule and DNG is effective in treating refractory/recurrent EMT， and can effectively improve the degree of dysmenorrhea and abnormal menstrual volume in patients. The mechanism may be related to improving vascular endothelial function， inhibiting the expression of tumor pathological factors， and correcting Th1/Th2 drift.

Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

ObjectiveTo investigate the possible mechanism of Shenfuhuang Formula （参附黄配方） in prevention and treatment of epsis-associated encephalopathy from the perspective of brain genomics. MethodsC57BL/6 mice were randomly divided into sham surgery group， sepsis group， and Shenfuhuang group， with 20 mice in each group. The sepsis group and Shenfuhuang group were induced to develop sepsis by cecal ligation and puncture （CLP） procedure. At 4 hours after modelling， Shenfuhuang group were gavaged with 2.5 g/（kg·d） of Shenfuhuang Formula， 0.5 ml each time， at 12 hours intervals， for a total of 4 times after modelling. Sepsis group and sham surgery group were given 0.5 ml of purified water orally. At 48 hours after modeling， the transcriptome sequencing was used to explore the differential gene expression in the effects of Shenfuhuang Formula on the brain regions of septic mice， and real-time PCR and ELISA were later used to further validate the differential gene and proteins expression. ResultsA total of 4605 genes were differentially expressed in Shenfuhuang group compared with sepsis group， of which 2353 genes were up-regulated and 2252 genes were down-regulated. According to the results of previous publications， six key genes were screened， including serine/threonine-protein kinase （Nek1）， myelin-associated glycoprotein （Mag）， endothelial cell-specific tyrosine kinase receptor （Tek）， a disintegrin and metalloproteinase with thrombospondin motifs 20 （Adamts20）， lymphocyte antigen 86 （Ly86）， and E3 ubiquitin-protein ligase （Traip）. Further genetic and protein validation revealed that， compared to the sham surgery group， the mRNA levels and corresponding protein levels of Nek1， Mag， Tek， Adamts20， Ly86， and Traip in the brain tissue of septic mice significantly reduced （P＜0.05）. In comparison to the sepsis group， Shenfuhuang group showed significantly increased mRNA levels and corresponding protein levels of Nek1， Mag， Tek， Adamts20， Ly86， and Traip （P＜0.05）. ConclusionThe potential therapeutic targets of Shenfuhuang Formula for treating sepsis-associated encephalopathy may be related to the Nek1， Mag， Tek， Adamts20， Ly86， and Traip genes and their encoded proteins.

Objective To understand the epidemiological characteristics and trends of postoperative pneumonia(POP)in tertiary general hospitals in Jiangsu Province,and provide theoretical basis for carrying out targeted pre-vention and control measures.Methods Surgery patients from 22 tertiary general hospitals in 12 cities in north,central,and south of Jiangsu Province from January 1,2022 to December 31,2023 were chosen as studied subjects,occurrence of POP was analyzed and compared.Results A total of 848 274 surgical procedures were performed in 22 hospitals,and 3 606 cases of POP occurred,with an incidence of 0.43％.The incidence in 2023 was 0.37％,which was lower than that in 2022(0.49％),with statistically significant difference(P＜0.001).The top three de-partments with high incidence of POP were neurosurgery(6.71％),cardiothoracic surgery(2.91％),and general surgery(0.77％).Among hospitals of different grades,the incidence of POP in tertiary first-class hospitals was 0.44％,which was higher than that in other tertiary hospitals(0.37％).There was no statistically significant difference in the incidence of POP between municipal and district/county hospitals(P＞0.05).The incidence of POP in hospitals with a bed:infection control full-time staff ratio＜200∶1 was lower than that in hospitals with the ratio ≥200∶1(0.39％vs 0.47％,P＜0.001),while the incidence of POP in hospitals with a proportion ≥30％of full-time staff being doctors was higher than that in hospitals with a proportion＜30％(0.45％vs 0.36％,P＜0.001).The incidence of POP in male patients was higher than that in female patients(0.62％vs 0.26％,P＜0.001).The incidence of POP in elderly patients aged≥65 was higher than that in patients aged＜65(0.73％vs 0.26％,P＜0.001).A total of 2 667 strains of infectious pathogens were detected,with the top three being Acine-tobacter baumannii,Klebsiella pneumoniae,and Pseudomonas aeruginosa,accounting for 28.95％,22.72％,and 15.45％,respectively.The detection rates of carbapenem-resistant Acinetobacter baumannii(CRAB),carba-penem-resistant Klebsiella pneumoniae(CRKP),and carbapenem-resistant Pseudomonas aeruginosa(CRPA)were 60.75％,21.45％,and 32.28％,respectively.The detection rate of CRKP decreased in 2023 compared with 2022,with statistically significant difference(P＜0.05).Conclusion The overall incidence of POP in tertiary general hos-pitals in Jiangsu Province is relatively low,but there are significant differences among different hospitals.There-fore,perioperative prevention and control measures should be carried out based on the epidemiological characteristics of patients.

Objective To explore the anti-intestinal fibrosis mechanism of Dahuang Zhechong pill.Methods Based on the network pharmacology method,the traditional Chinese medicine systems pharmacology database and analysis platform,SwissTargetPrediction database and metabolomics technology was used.OmicsNet 2.0 platform combined with the findings of network pharmacology and metabolomics,and molecular simulation docking and molecular biology methods were used to study the mechanism of anti-intestinal fibrosis of Dahuang Zhechong pill.Results Dahuang Zhechong pill contains 142 potential active ingredients and 855 anti-intestinal fibrosis targets.The 10 core ingredients(quercetin,acacetin,oroxylin a,kaempferol,moslosooflavone,panicolin,etc.)may play a role in regulating lipid metabolism and atherosclerosis,EGFR tyrosine kinase inhibitor resistance,HIF-1 signaling pathway,TNF signaling pathway and IL-17 signaling pathway.Metabolomics results showed that 59 endogenous substances(oxaloacetic acid,ethylthioisonicamide,6-benzylaminopurine,tyrosine and cortisol,etc.)may be the key metabolites of this drug against intestinal fibrosis.Central carbon metabolism,TCA cycle and amino acid metabolism were the key mechanisms,EGFR,AKT1,MAPK1,PTPN11,CASP3,PPARG,MET and PDGFRB may be the core targets.Dahuang Zhechong pill could significantly improve the levels of colorectal edema,inflammatory factors,inflammatory cell infiltration,collagen fiber deposition and α-SMA expression in mice with intestinal fibrosis,reduce the expression levels of pro-inflammatory factors IL-17 and IL-23 in serum,and increase the level of anti-inflammatory factor IL-10.Molecular dynamics simulations demonstrated stable conformational binding between core active ingredients and key targets.Conclusion Dahuang Zhechong pill may regulate EGFR/AKT1/MAPK mediated metabolism-inflammation interaction network through flavonoid components,and can improve intestinal fibrosis in multiple dimensions through molecular validation.

Objective To investigate the effects of integrating pelvic floor magnetic stimulation and medium-frequency pulsed electrotherapy with biofeedback on alleviating obstructed defecation symptoms in patients diagnosed with pelvic floor spasm syndrome.Methods A total of 133 patients diagnosed with pelvic floor spasm syndrome at the Gastrointestinal Surgery Outpatient and Inpatient Departments of the Third Hospital of Hebei Medical University between January 2017 and January 2025 were enrolled in this study.All patients underwent two sessions of conventional biofeedback therapy.According to the additional treatments they received,the patients were catego-rized into four groups:the Control group(received biofeedback therapy only);the Magnetic Stimulation group(received two additional sessions of pelvic floor magnetic stimulation);the Electrical Stimulation group(received two additional sessions of medium-frequency pulse electrical therapy);and the Magnetic-Electric Combined group(received two additional sessions of both pelvic floor magnetic stimulation and medium-frequency pulse electrical therapy).The improvement in obstructed defecation symptoms was evaluated before treatment,after treatment,and at the 3-month follow-up across all four groups.Results A total of 133 patients diagnosed with pelvic floor spasm syndrome were enrolled in this study.After a 3-month follow-up period,8 patients were lost to follow-up(6.0%).Consequently,125 patients completed the follow-up and were included in the final analysis.These patients were distributed across four groups:the control group(n=32),the magnetic stimulation group(n=30),the electrical stimulation group(n=31),and the combined magneto-electric stimulation group(n=32).Compared with biofeedback therapy alone,combination therapy led to a greater reduction in the need for manual assistance during defecation,the sensation of incomplete evacuation,and the requirement for straining during defecation,with the most pronounced improvements observed in the combined magneto-electric stimulation group.Conclusions The integration of biofeedback,pelvic floor magnetic stimulation,and medium-frequency pulse electrotherapy can significantly alleviate symptoms including straining during defecation,the sensation of incomplete bowel evacua-tion,and reduce the need for manual assistance.Moreover,this combined approach contributes to the stabilization and maintenance of therapeutic effects in the short term.
