Objective To elucidate the changes in the gut microbiota and molecular mechanism of huaier in enhancing the efficacy of oxaliplatin (OXA) chemotherapy in gastric cancer (GC). Methods The effects of huaier on the gut microbiota structure and intestinal barrier function in MKN45-bearing mice were analyzed by using 16S rRNA sequencing, RT-qPCR, and IHC. UPLC-MS and network pharmacology, as well as in vivo experimental approaches, were employed to investigate the key bioactive constituents of huaier systematically and elucidate the underlying mechanisms by which huaier exerts therapeutic effects against GC. The expression of the PI3K/AKT/SREBP pathway was detected in cancer cells and tissues via Western blot analysis. The safety profile of huaier combined with OXA was verified through serum biochemistry and HE-stained tissue section analyses. Results Huaier inhibited the PI3K/AKT/SREBP pathway by increasing the abundance of Akkermansia muciniphila, reduced lipid droplet deposition, and ultimately enhanced the sensitivity to OXA in the treatment of GC. Conclusion This study demonstrates the value of huaier in gastric cancer treatment by enhancing chemosensitivity and provides novel insights into its systemic therapeutic effects through molecular mechanisms and gut microbiota modulation.

Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Objective:To investigate the clinical value of the Nomogram model based on two-dimensional shear wave elastography(2D-SWE)combined with biochemical indicators in the diagnosis of moderate and severe metabolic-associated fatty liver disease(MAFLD).Methods:A total of 170 patients with MAFLD diagnosed by ultrosound image in the health management center of the Second People's Hospital of Wuhu from Jan 2023 to Dec 2023 were divided into mild,moderate and severe groups according to two-dimensional ultrasound images,and 111 healthy volunteers were recruited as control group in the same period.Multivariate logistic regression analysis was used to screen independent risk factors for moderate and severe MAFLD and construct a predictive model.The diagnostic efficacy of the ROC model was plotted,and the Nomogram model was used to conduct internal verification.Results:Multivariate logistic regression analysis showed that liver stiffness measurement(LSM),platelet count(PLT)and hepatic steatosis index(HSI)were the independent risk factors for the diagnosis of moderate and severe MAFLD.The area under the curve(AUC)of LSM,PLT and HSI was 0.940(95%CI:0.911-0.969),with a sensitivity was 87.5%and a specificity was 88.1%.The internal validation showed that the model had high accuracy and stability.Conclusion:The Nomogram model based on LSM combined with PLT and HSI can effectively diagnose moderate and severe MAFLD,providing a reliable evidence for early clinical intervention and adjustment of therapeutic measures.

Objective To observe impact factors of average glandular dose(AGD)of full field digital mammography(FFDM)and digital breast tomosynthesis(DBT)under breast Combo mode.Methods Totally 169 subjects who received FFDM and DBT under Combo mode were collected retrospectively.The breast compression thickness,tube voltage,tube current and AGD of FFDM and DBT exposure at cranio-caudal(CC)and mediolateral oblique(MLO)positions of bilateral breast were recorded.FFDM or DBT exposure conditions and AGD among different breast compression thickness and breast types were compared,and their correlations were analyzed.The impacts of breast compression thickness and breast density on AGD of FFDM or DBT were observed.Results There were significant differences in tube voltage,tube current and AGD of FFDM or DBT among different breast compression thicknesses(all P＜0.001).With the increase of breast compression thickness,tube voltage,tube current and AGD of FFDM or DBT all increased(all P＜0.001).There were statistical differences in breast compression thickness,tube voltage,tube current and AGD of FFDM or DBT among different types breast(all P＜0.001).Hierarchical analysis showed that,when breast compression thickness was＜50 mm,50-59 mm and＞59 mm respectively,statistical differences in AGDFFDM and AGDDBT among different breast types at CC or MLO positions were found(all P＜0.001).Under the same breast compression thickness,tube current,AGDFFDM and AGDDBT of FFDM or DBT all increased with the increase of breast density(all P＜0.001),while tube voltage of FFDM or DBT had no obvious change(all P＞0.05).Breast compression thickness and breast density were both independent factors of AGD of FFDM or DBT(all P＜0.001).Conclusion Under breast Combo mode,breast compression thickness and gland density both had impacts on AGD of FFDM or DBT,and the former had more significant impact on AGD.

Objective To evaluate the influence of precision symptom management based on Internet plus on patients with corneal ulcer.Methods An intervention team was set up to build an Internet+precise symptom management plan for corneal ulcer patients,and the research involved 120 patients with corneal ulcers in a tertiary A hospital in Chongqing from July to December 2023.The patients were divided into an intervention group(n=60)and a control group(n=60)according to the random number table generated by SPSS.Symptom assessment questionnaires were completed once a day during hospitalization and twice a week after discharge,and visual acuity,quality of life,and self-efficacy were assessed on the day of admission and 4 weeks after discharge.Results A total of 112 patients completed the study.The data of 54 cases in the intervention group and 58 cases in the control group were statistically analyzed.During hospitalization and within 4 weeks after discharge,the reported symptom threshold events in the intervention group were lower than those in the control group(P=0.031,P=0.027),and the visual acuity,quality of life,and self-efficacy of the intervention group patients were better than those of the control group patients at the end of the 4th week,with statistically significant differences(all P＜0.05).Conclusion Symptom management program based on internet plus can alleviate patients'symptom experience,improve patients'visual acuity,quality of life and self-efficacy.

Objective:To investigate the determinants of hospitalization costs for joint replacement surgeries in a tertiary public hospital in Beijing from 2011 to 2023.Methods:Structural variation degree,grey relational analysis,and multiple linear regression were applied to assess the impact of policy reforms and clinical factors.Results:Average hospitalization cost per visit decreased markedly in 2013,rose steadily to a peak in 2019,and then declined.Medical pricing policies significantly influenced both cost levels and structure.Material cost consistently showed the strongest association with total cost,while treatment cost became the second most influential factor after four rounds of price adjustments.Length of stay,number of secondary diagnoses,number of additional surgeries,number of procedures,and ICU admission had impact on the average hospitalization cost per visit,with statistical significance.Conclusion:Price adjustments for consumables and treatment services are the main drivers of average hospitalization costs for joint replacement surgeries.Further optimization of cost structures and medical service pricing is required to better reflect labor value,while the labor value is required to be promoted.The length of stay and operation amount have impact on the average hospitalization cost per visit.It is needed to focus on improving efficiency and care quality.

Objective To investigate the effect of transcutaneous auricular vagus nerve stimulation(taVNS)on quality of early postoperative recovery in patients undergoing thoracoscopic lung resection.Methods A total of 168 patients scheduled for elective thoracoscopic lung resection(wedge resection,segmentectomy,lobectomy)under general anesthesia were enrolled and randomly assigned to active-taVNS group(group T)or sham-taVNS group(group S)(n=84).Participants received four consecutive 30-minute sessions of active stimulation or sham stimulation at four time points:(1)the afternoon prior to the surgery,(2)the morning of the surgery,(3)following extubation,and(4)the first afternoon post-surgery.The Quality of Recovery-15(QoR-15)scores of the patients,the Numerical Rating Scale(NRS)scores at rest and during cough at 24,48,and 72 hours after surgery were recorded;and the usage of opioids within 48 hours after surgery was recorded;the duration of chest tube indwelling,incidence of severe pulmonary complications,postoperative hospital stay and adverse reactions to the stimulation(such as nausea and vomiting,fever,constipation,dizziness and itching)were observed.Results Compared with group S,group T exhibited significantly higher QoR-15 scores at 24,48,and 72 h postoperatively,lower NRS pain scores during resting and coughing,and reduced opioid consumption within 48 hours postoperatively(P<0.05).There were no significant differences between the two groups in the duration of chest tube indwelling,incidence of severe pulmonary complications,hospital stay,and the incidence of adverse reactions to the stimula-tion(P>0.05).Conclusion TaVNS can significantly improve quality of early postoperative recovery in patients undergoing thoracoscopic lung resection,and provide more effective postoperative analgesia without increasing the risk of postoperative complications.
