OBJECTIVE To construct a scientific and systematic quality control index system for intravenous medication admixture， so as to ensure the safety of drug use and improve the quality of medical service. METHODS Based on literature analysis and cross-sectional survey， an initial indicator framework was formulated. Opinions were then gathered through two rounds of Delphi expert consultations， and the expert authority coefficient and Kendall’s coefficient of concordance were calculated to evaluate the consistency. Ultimately， the analytic hierarchy process was employed to determine the weights of each indicator and test for consistency in order to establish a scientific and systematic quality control indicator system for intravenous medication admixture. RESULTS The study conducted two rounds of expert consultation with an average positive coefficient of 95.92% and an average authority coefficient of 0.983. In the second round of the Delphi consultation， the Kendall’s coefficients of concordance for the first-， second-， and third-level indicators were 0.306， 0.440， and 0.394， respectively， all significantly higher than those in the first round （0.211， 0.274， 0.379）. The final quality control system for intravenous medication admixture consisted of 6 first-level indicators （personnel， medicines and consumables， facilities and equipment， process management， environmental hygiene， and outcomes）， 17 second-level indicators （e.g.， education and training， staffing structure， workload， medication management， consumables management， and equipment maintenance）， and 44 third-level indicators （e.g.， average daily workload per person， proportion of pharmacy professionals， competency assessment pass rate， work system assessment pass rate， continuing education frequency and pass rate， and medication inventory accuracy）. CONCLUSIONS The quality control system for intravenous medication admixture developed in this study demonstrates strong authority and scientific rigor， providing a theoretical basis and practical tool for the standardized management of intravenous medication admixture quality in hospitals.

ObjectiveTo investigate the mechanism underlying the weight loss effect of electrothermal acupuncture （ETA） in diet-induced obese （DIO） model mice based on the hypoxia-inducible factor-1α （HIF-1α）/sphingosine-1-phosphate （S1P）sphingosine-1-phosphate receptor 3 （S1PR3） signaling pathway-mediated macrophage polarization. MethodsAn obesity mouse model was established by continuously feeding at a high-fat diet （HFD） for 8 weeks. Twenty successfully modeled obese mice were randomly divided into a model group and an electrothermal acupuncture （ETA） group with 10 mice per group， both of which continued to receive the HFD till week 12. Another 10 mice were assigned to the normal group and fed a standard chow diet continuously for 12 weeks. Starting from week 9 of the experiment， mice in the ETA group received electrothermal acupuncture stimulation at Zhongwan （CV12）， bilateral Tianshu （ST25）， and bilateral Zusanli （ST36） for 30 minutes per session， with the instrument current set at （40±0.5）mA and a constant temperature of （40±0.5）℃. Mice in the normal group and the model group were restrained in the same manner for 30 minutes without acupuncture. All interventions were performed once every other day for a total of 4 weeks. Ten hours after the final intervention， the body weight， waist circumference， and body length of mice in each group were measured， and Lee's index was calculated. Serum biochemical analysis was performed to assess fasting blood glucose （FBG）， total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， blood urea nitrogen （BUN）， and creatinine （Cr）. Serum leptin （LEP） and adiponectin （ADPN） levels， as well as sphingosine-1-phosphate （S1P） levels in epididymal white adipose tissue （eWAT）， were detected by ELISA. Histomorphological changes in eWAT were monitored via HE staining. Flow cytometry was used to analyze macrophage subtype-related indexes in eWAT， including the total proportion of macrophages， the proportion of M1 macrophages， the proportion of M2 macrophages， and the M1/M2 ratio. Antibody array technology was used to determine the levels of differentially expressed inflammatory factors in eWAT between the model and blank groups， as well as between the ETA and model groups. Western blot and qPCR were used to detect the protein and mRNA expression levels of HIF-1α and S1PR3 in the eWAT， respectively. ResultsCompared to the normal group， the model group showed significantly increased body weight， Lee's index， waist circumference， and FBG， TC， TG， HDL-C， LDL-C， AST， and ALT levels， upgraded LEP and S1P levels， decreased ADPN level and ADPN/LEP ratio， elevated proportion of M1 macrophages and the M1/M2 ratio， reduced proportion of M2 macrophages， and upregulated protein and mRNA expression levels of HIF-1α and S1PR3 （P＜0.05 or P＜0.01）. With the exception of HDL-C， all the abovementioned indicators in the ETA group were significantly improved compared to the model group （P＜0.05 or P＜0.01）. Analysis of differentially expressed inflammatory cytokines revealed that， compared to the normal group， the levels of interleukin-1β （IL-1β）， interferon-γ （IFN-γ）， interleukin-6 （IL-6）， and interleukin-12p70 （IL-12p70） in the eWAT of the model group were elevated； conversely， the levels of interleukin-17 （IL-17）， interleukin-5 （IL-5）， IL-6， and interleukin-23 （IL-23） in the eWAT of the ETA group decreased compared to the model group （P＜0.05 or P＜0.01）. ConclusionETA exerts a weight-reducing effect in obese model mice， and the mechanism may involve inhibition of the HIF-1α/S1P/S1PR3 signaling pathway activation， which shifts macrophage polarization from the M1 to M2 phenotype， thereby alleviating chronic inflammation.

Objective To investigate the cognition level and behavior compliance of blood pressure measurement in community residents and analyze the related influencing factors, and to provide evidence for community health management and blood pressure control. Methods A questionnaire survey was conducted to investigate 4470 community patients. Questionnaires included basic personal information，blood pressure measurement cognition, and blood pressure measurement behavior related issues. SPSS 19.0 was used to analyze the basic information, blood pressure measurement cognition, and pressure measurement behavior of the survey subjects. Logistic regression was performed to analyze relevant factors affecting blood pressure measurement cognition and behavior compliance. Results The overall cognitive compliance rate for blood pressure measurement among the visiting community patients was 31.52%. Age, education level, and chronic disease had a statistically significant impact on the cognitive knowledge (P<0.05). The overall behavior compliance rate of blood pressure measurement among the community patients was 23.69%. The cognition, age and education had a statistically significant impact on the overall behavior compliance rate of blood pressure measurement (P<0.05). Conclusion The cognitive level and standardized behavior of blood pressure measurement of community patients need to be improved. More attention should be paid to the elderly, low education level residents and community residents without chronic diseases, to promote community residents to form correct and standardized behavior of blood pressure measurement through health education.

By examining the records related to the Fengfu （GV 16） acupoint in BIAN Que Heart Book （《扁鹊心书》） compiled by the Song Dynasty physician DOU Cai， this study analyzed various aspects， including the differentiation of conditions treated with Fengfu （GV 16） acupoint， the theoretical foundation for selection of Fengfu （GV 16） acupoint， the application of needling manipulation， and the sensation of obtaining qi during acupuncture. The findings suggest that DOU Cai's approach to utilizing Fengfu （GV 16） acupoint differs from traditional methods， particularly emphasizing the effectiveness of achieving a sensation of heat and numbness. His unique techniques include transverse insertion at Fengfu （GV 16） acupoint and penetrated insertion to Fengchi （GB 20） and Yifeng （TE 17） acupoints. The records of Fengfu （GV 16） acupoint in BIAN Que Heart Book provide a valuable reference for its modern clinical application and further development.

ObjectiveTo explore the mechanism of herbal cake-separated moxibustion using the classical formula Xiaoyaosan in alleviating neuroimmune inflammatory responses in chronic fatigue syndrome （CFS） rats， based on the regulation of the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear transcription factor-κB （NF-κB） signaling pathway. MethodsFifty SPF-grade SD rats aged 6-8 weeks were randomly divided into five groups： Normal group， model group， sham herbal cake moxibustion group， Chinese medicine intragastric administration group， and herbal cake-separated moxibustion group， with 10 rats in each group. Except for the normal group， all other groups underwent a 21-day modeling process， followed by behavioral testing. The herbal cake-separated moxibustion and sham herbal cake moxibustion groups received interventions at the Shenque （CV8）， Guanyuan （CV4）， Zusanli （ST36）， and Qimen （LR14） acupoints. The Chinese medicine intragastric administration group was treated with a Xiaoyaosan suspension via gavage. Behavioral tests were conducted after 10 days of continuous intervention. Serum levels of interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α）， as well as hippocampal levels of IL-1β， IL-6， TNF-α， and NF-κB， were detected by enzyme-linked immunosorbent assay （ELISA）. Morphological changes in the hippocampus were observed using hematoxylin-eosin （HE） staining. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression levels of TLR4， MyD88， and NF-κB in the hippocampus. Western blot analysis was performed to detect the relative expression levels of TLR4， MyD88， NF-κB， and p65 proteins in the hippocampus. ResultsCompared with the normal group， the model group showed a significant decrease in upright times during the open field test （P<0.01）， as well as significant reductions in total movement distance， resting time， and center region duration （P<0.01）. In the tail suspension test， immobility time increased （P<0.01）， and struggle times decreased （P<0.01）. Serum and hippocampal levels of IL-1β， IL-6， and TNF-α， as well as hippocampal NF-κB levels and TLR4， MyD88， and NF-κB mRNA expression， were significantly elevated （P<0.01）. After treatment， compared with the model group， the total movement distance and upright times in the open field test were significantly increased in all treatment groups （P<0.01）， while resting time and center region duration were notably prolonged （P<0.05， P<0.01）. Immobility time in the tail suspension test was significantly shortened （P<0.01）， and struggle times significantly increased （P<0.05）. Serum and hippocampal levels of IL-1β， IL-6， TNF-α， hippocampal NF-κB levels， and TLR4 and NF-κB mRNA expression were significantly reduced （P<0.05， P<0.01）. Compared with the sham herbal cake moxibustion group， the herbal cake-separated moxibustion group showed a significant extension in center region duration during the open field test （P<0.05） and a significant increase in upright times （P<0.01）. In the tail suspension test， immobility time was reduced （P<0.01）， and struggle times increased （P<0.01）. Serum TNF-α levels in the Chinese medicine intragastric administration group were significantly reduced （P<0.01）， while serum IL-6 levels， as well as hippocampal levels of IL-1β， TNF-α， NF-κB， and TLR4， MyD88， and NF-κB mRNA expression， were significantly decreased in both the Chinese medicine intragastric administration group and the herbal cake-separated moxibustion group （P<0.05， P<0.01）. Compared with the Chinese medicine intragastric administration group， the herbal cake-separated moxibustion group exhibited significantly increased upright times in the open field test （P<0.01）. In the tail suspension test， immobility time was reduced （P<0.01）， and struggle times increased （P<0.01）. Serum IL-1β， hippocampal TNF-α levels， and TLR4， MyD88， and NF-κB mRNA expression were significantly decreased （P<0.05， P<0.01）. ConclusionHerbal cake-separated moxibustion effectively improves fatigue and memory function in CFS rats， regulates neuroimmune inflammatory responses， and its mechanism may be related to the modulation of the TLR4/MyD88/NF-κB signaling pathway.

Objective:To investigate the association between blood selenium levels and sex hormones in Chinese men aged 18-79 years.Methods:Data were derived from the China National Human Biomonitoring survey conducted in 2017-2018, with a final sample size of 5 414 men. General demographic characteristics, behavioral habits, and dietary frequency were collected through questionnaires and physical examinations. Fasting blood samples were collected to measure blood lead, serum testosterone, and estradiol levels. Complex sampling linear regression models were used to analyze the associations between blood selenium levels and testosterone, estradiol, and the testosterone/estradiol ratio, adjusting for confounding factors including age, education level, marital status, smoking status, alcohol consumption, seafood intake, soy product intake, protein supplement intake, BMI, and diabetes status.Results:The mean age of the 5 414 participants was (46.85±27.91) years; 4 774 (91.65%) were of Han ethnicity and 4 505 (86.68%) were married. The median ( Q1, Q3) blood selenium concentration in men was 97.80 (80.64, 116.99) μg/L. After adjusting for confounding factors, the complex sampling linear regression model revealed negative associations between blood selenium levels and both testosterone levels and the testosterone/estradiol ratio, with a significant linear trend ( Ptrend<0.05). Compared with the Q1 group, the β (95% CI) values for testosterone in the Q2, Q3, and Q4 groups were -0.02 (-0.06 to 0.02), -0.03 (-0.08 to 0.01), and -0.06 (-0.09 to -0.02), respectively. Similarly, the β (95% CI) values for the testosterone/estradiol ratio in the Q2, Q3, and Q4 groups were -0.01 (-0.03 to 0.02), -0.01 (-0.04 to 0.04), and -0.03 (-0.06 to -0.01), respectively. Subgroup analysis indicated stronger associations between blood selenium levels and testosterone/estradiol levels in non-smoking and obese men (BMI≥28 kg/m2). Conclusion:Blood selenium levels are negatively associated with testosterone levels and the testosterone/estradiol ratio in Chinese adult males.

Objective To investigate the predictive value of the diagnostic model constructed by CT radiomics combined with clin-ical and CT features for the P53 mutation status in lung adenocarcinoma.Methods The data of 177 patients with lung adenocarcinoma were retrospectively collected,including 75 cases of P53 mutant type and 102 cases of wild type.They were randomly divided into training cohort(n=123)and validation cohort(n=54)in a 7∶3 ratio.The region of interest(ROI)was delineated using MaZda software,and the features were screened using the least absolute shrinkage and selection operator(LASSO).The predictive model was devel-oped based on logistic regression analysis,and its diagnostic efficacy was evaluated.Results There were statistically significant differences in lesion diameter,maximum solid component diameter,lobulation sign,and lymph node metastasis between the two groups in the training cohort(P＜0.05).The area under the curve(AUC)in the training cohort of the radiomics score model,clinical imaging feature model,and combined model were 0.778,0.759,and 0.817,and the AUC in the validation cohort were 0.668,0.722,and 0.783,respectively.The clinical decision curve suggested that the combined model demonstrated superior clinical net benefits.Conclusion The combined model constructed by CT radiomics,lesion diameter,and lymph node metastasis has better predictive value for the P53 mutation status in lung adenocarcinoma.

ObjectiveTo compare colonoscopy compliance rates under different screening strategies, to explore ways to enhance colonoscopy compliance among residents with colorectal carcinoma. MethodsResidents aged between 50‒80 years were recruited through extensive community outreach and voluntary participation. A total of 210 630 residents who participated in the colorectal carcinoma screening program in Jiading District, Shanghai, between 2013 and 2019 were selected as the research subjects. All subjects underwent a colorectal carcinoma risk assessment questionnaire survey and two fecal occult blood tests (FOBT). Positive results in the initial screening were defined as a positive questionnaire survey or a positive result in at least one FOBT. Participants with positive initial screening results were advised to undergo colonoscopy screening in a hospital. Colonoscopy results were collected from hospital reports and physician follow-ups. Compliance with colonoscopy was analyzed under different screening strategies to identify possible factors influencing residents’ willingness to undergo the procedure. ResultsA total of 21 403 individuals (10.16%) were identified as positive with the questionnaire survey, 31 595 individuals (15.00%) tested positive with at least one FOBT. Combined questionnaire and FOBT positivity was observed in 3 501 individuals (1.66%). Among the 48 453 individuals with positive initial screening results, 17 230 (35.56%) underwent colonoscopy, and a total of 315 cases of colorectal cancer were detected. The sensitivity, specificity value of FOBT initial screening were 83.81% and 84.66%, respectively. According to the combined risk assessment and FOBT initial screening preliminary screening, the lowest colonoscopy compliance rate (25.63%) was observed among individuals with only a positive questionnaire, and the highest compliance rate (52.55%) was among those with both positive questionnaire survey and two positive FOBT results. Multivariate analysis revealed that FOBT positivity had the greatest impact on colonoscopy compliance. Those with one positive FOBT test result were 2.64 times more likely to undergo colonoscopy screening than those with negative FOBT results, while individuals with two positive FOBT results were 3.18 times more likely to do so. After adjusting for FOBT results, individuals with positive questionnaire survey results were 1.43 times more likely to undergo colonoscopy screening than those with negative results (95%CI: 1.34‒1.52). Compared to questionnaire-based risk assessment, FOBT results were more influential in determining compliance with colonoscopy. ConclusionThe choice of initial screening method significantly impacts residents’ compliance with colonoscopy. While implementing colorectal carcinoma screening programs, it is necessary to strictly adhere to screening protocols, including risk assessment and FOBT. Additionally, efforts should be made to raise public awareness, encouraging residents to actively participate in risk assessments and FOBT, thereby improving their compliance with colonoscopy.

ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.

Objective:To investigate the feasibility and safety of laparoscopic purse- string suture clamps combined with multi-functional seal caps for esophagojejunal Roux-en-Y anastomosis during total laparoscopic radical total gastrectomy (TLTG).Methods:This was a retrospective descriptive study of 42 patients with primary gastric malignancies who underwent TLTG at the First Affiliated Hospital of Nanjing Medical University that utilized laparoscopic purse-string suture clamps and multi-functional seal caps for esophagojejunal anastomosis between May, 2024 and January, 2025. The cohort included 33 males and 9 females, with a mean age of (67.7 ±9.5) years and a mean body mass index (BMI) of (23.9±2.9) kg/m 2. The American Society of Anesthesiologists (ASA) physical status classifications were I - II in 40 patients and III in 2 patients, and all patients were definitively diagnosed preoperatively via gastroscopy, dual-energy CT, and/or MRI. Tumor locations included the gastroesophageal junction (GEJ) in 28 cases (Siewert type II - III), the upper third of the stomach in 12 cases, and the middle third in 2 cases. The median distance of esophageal invasion was 1.3 cm, though in 10 cases this was ≥2 cm. Preoperative TNM staging was I-II in 17 patients and III in 25 patients. Surgical outcomes including operative time, anastomosis time, intraoperative blood loss, pathological results, and postoperative recovery were retrospectively analyzed. Results:All 42 operations were successful. The mean operative time was(212.5±26.4) minutes, and the average time from multi-functional seal cap placement to completion of the esophagojejunal anastomosis was (54.2±7.5) minutes. Mean intraoperative blood loss was (79.9±21.3) ml. Postoperative pathology confirmed R0 resection in all specimens, with a mean proximal esophageal margin distance of (2.1±1.6) cm. Furthermore, (51.9±15.1) lymph nodes on average were harvested from each patient; the mean time to oral intake was (149.5±41.4) hours; and the mean hospital stay was (11.3±5.4) days. Postoperative complications occurred in 6 patients: anastomotic leakage ( n=2), residual intra-abdominal infection ( n=1), pulmonary infection ( n=3), and Clavien-Dindo grade III or higher complications occurred in 2 patients. No recurrence, mortality, or anastomosis-related complications were observed within a median follow-up of 5.8 months (range 3.5-11.2). Conclusion:We find the application of the laparoscopic purse-string suture clamps and multi-functional seal caps for esophagojejunal anastomosis in TLTG to be safe and feasible, with satisfactory short-term outcomes.
