ObjectiveTo develop a core outcome set for musculoskeletal pain （MKP-COS） and a specific outcome set for traditional Chinese medicine external treatment （MKP-SOS-ETCM）， providing a standardized basis for clinical research in musculoskeletal pain and serving as a reference for core outcome set （COS） development in related fields. MethodsExisting COS studies on musculoskeletal pain （MKP） were systematically searched， and core outcome indicators were extracted to form an initial item pool. The Delphi method was used， in which experts were invited to reach consensus on MKP-COS and MKP-SOS-ETCM. The inclusion criteria for consensus are set as an importance score of 7-9 points with ≥75% of experts reaching agreement. ResultsA total of 47 COS studies were included， and after discussion and consolidation， a preliminary item pool containing 34 outcome indicators was established. After three rounds of Delphi expert consensus， MKP-COS was identified， including five outcomes including pain， motor function， joint range of motion， activities of daily living， and adverse events/ adverse reactions； MKP-SOS-ETCM included six outcomes involving stiffness （including morning stiffness）， joint tenderness count， work status/ productivity， overall physician assessment， structural damage， and muscle strength. ConclusionThis study has established MKP-COS and MKP-SOS-ETCM， forming a dual-dimensional outcome assessment system integrating both disease commonality and intervention specificity.

Objective To investigate the status quo of limited social participation in young patients with ankylosing spondylitis (AS), and analyze its influencing factors. Methods Using the random number table method, a simple random sampling method was employed to select 320 young patients with ankylosing spondylitis who were admitted to the First Affiliated Hospital of Naval Medical University from June 2023 to June 2025. Chinese version of social participation scale was applied to evaluate the level of social participation of patients. The above patients were classified into unlimited group (n=148) and limited group (n=172). Logistic regression analysis was performed to analyze the independent influencing factors for limited social participation. Results Compared with the unlimited group, the limited group exhibited longer course of AS, higher BASDAI score, BASFI score, HAMA score, HAMD score and ASQoL score as well as lower PSSS score (P<0.05). Logistic regression analysis suggested that course of disease, high disease activity score, high anxiety score, high depression scores and low social support scores are the relevant factors for the restricted social participation of young patients with ankylosing spondylitis. Conclusion The phenomenon of limited social participation is common in young patients with AS, and its occurrence is the result of a combination of factors such as disease course, disease activity, anxiety, depression and social support level.

ObjectiveTo investigate the impact of preoperative frailty on the prognosis of patients with pancreatic cancer who underwent pancreaticoduodenectomy. MethodsA retrospective analysis was conducted on the clinical data of 435 pancreatic cancer patients who underwent pancreaticoduodenectomy at Sun Yat-sen Memorial Hospital of Sun Yat-sen University. Preoperative frailty was assessed using the FRAIL questionnaire. Binary logistics regression analysis was employed to identify factors influencing frailty， and Cox regression analysis was used to evaluate the effect of frailty on survival. According to the demographic characteristics， subgroup analyses were performed on the effect of frailty on prognosis of patients with pancreatic cancer with pancreaticoduodenectomy. ResultsAmong the 435 patients enrolled， 119 （27.4%） exhibited frailty， while 316 （72.6%） did not. Significant differences were observed between the two groups in various clinical parameters， including age， body mass index， American Society of Anesthesiologists （ASA） score， postoperative red blood cell transfusion， postoperative abdominal abscess， serum levels of glycoantigens 199， glycoantigens 125， and alpha fetoprotein， leukocyte count， neutrophil， high density lipoprotein （HDL） level， and pain intensity （P＜0.05）. Advanced age and an ASA score of Ⅲ were identified as risk factors for frailty， whereas HDL level was a protective factor. Non-frail patients had better postoperative survival times than frail patients. HDL was determined to be an independent protective factor for prognosis， while LDL was an independent risk factor. ConclusionsThis study demonstrates that preoperative frailty is a significant predictor of poor prognosis in pancreatic cancer patients who underwent pancreaticoduodenectomy.These findings suggest that preoperative frailty assessment and targeted interventions to improve nutritional and metabolic status could potentially enhance postoperative survival and quality of life in pancreatic cancer patients.

Objective To explore the role and related mechanism of neutrophil membrane-coated poly(lactic-co-glycolic acid) (PLGA) nanoparticles (Neu-NP) in cardiac repair after acute myocardial ischemia-reperfusion (MI/R) injury in mice. Methods The male C57 mouse model of acute MI/R injury was established and randomly divided into three groups: PBS control group (injection of 200 μL PBS), NP treatment group (injection of 0.5 mg/mL NP 200 μL), and Neu-NP treatment group (injection of 0.5 mg/mL Neu-NP 200 μL). Neutrophil membranes were extracted and fused with PLGA nanoparticles to construct biomimetic Neu-NP. The in vivo homing ability of Neu-NP was assessed using ex vivo imaging technology in the MI/R injury model, and the expression levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the myocardium were measured using enzyme linked immunosorbent assay one day and three days after administration. Echocardiography was used to determine cardiac function indicators of MI/R injured mice 28 days post-administration. Immunofluorescence staining was used to observe angiogenesis repair and inflammatory cell infiltration in mouse heart tissue. Results Neu-NP, engineered by integrating neutrophil membranes with nanoparticles, inherited surface receptors (TNF-αR and IL-6R) and functioned as decoys for inflammatory targeting. Compared with the PBS control group and NP treatment group, the secretion levels of TNF-α and IL-6 in the damaged myocardium of the Neu-NP treatment group were significantly decreased one and three days after administration (P＜0.05); 28 days after administration, the cardiac ejection fraction in the Neu-NP treatment group was significantly higher than that in the other two groups (P＜0.05). Immunofluorescence staining indicated a significant increase in the proportion of angiogenesis in the myocardial infarction area and a significant reduction in inflammation cell infiltration (P＜0.05). Conclusions Neu-NP plays an important role in cardiac tissue repair after MI/R injury by alleviating inflammatory factors in the damaged area and promoting angiogenesis.

Cerebral edema is characterized by fluid accumulation, and the glymphatic system (GS) plays a pivotal role in regulating fluid transport. Using the Tenecteplase system, magnesium salt of salvianolic acid B/ginsenoside Rg1 (SalB/Rg1) was injected intravenously into mice 4.5 h after middle cerebral artery occlusion and once every 24 h for the following 72 h. GS function was assessed by Evans blue imaging, near-infrared fluorescence region II (NIR-II) imaging, and magnetic resonance imaging (MRI). SalB/Rg1 had significant effects on reducing the infarct volume and hemorrhagic transformation score, improving neurobehavioral function, and protecting tissue structure, especially inhibiting cerebral edema. Meanwhile, the influx/efflux drainage of GS was enhanced by SalB/Rg1 according to NIR-II imaging and MRI. SalB/Rg1 inhibited matrix metalloproteinase-9 (MMP-9) activity, reduced cleaved β-dystroglycan (β-DG), and stabilized aquaporin-4 (AQP4) polarity, which was verified by colocalization with CD31. Our findings indicated that SalB/Rg1 treatment enhances GS function and attenuates cerebral edema, accompanying the regulation of the MMP9/β-DG/AQP4 pathway.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:To investigate the iodine nutrition status of children aged 8 - 10 and pregnant women in Xining City, Qinghai Province.Methods:From 2019 to 2021, a stratified cluster sampling method was used to divide 7 counties (districts) under the jurisdiction of Xining City, Qinghai Province into 5 sampling areas according to east, west, south, north, and center each year. One township (town, street) was selected from each area. Forty non boarding students aged 8 to 10 from each primary school (half male and half female, age balanced) and 20 pregnant women from each township (town, street) location were selected to collect edible salt samples at home and a random urine sample to measure salt iodine and urinary iodine level. B-ultrasound was used to measure thyroid volume in children and the goiter rate was calculated.Results:A total of 6 534 samples of household edible salt were collected from children and pregnant women, with an average salt iodine concentration of 25.58 mg/kg. The coverage rate of iodized salt was 97.50% (6 371/6 534), and the qualified iodized salt consumption rate was 89.46% (5 845/6 534). A total of 4 362 urine samples were collected from children, with a median urinary iodine level of 183.10 μg/L. The difference between different years was statistically significant ( H = 20.27, P < 0.001). A total of 2 169 urine samples were collected from pregnant women, with a median urinary iodine level of 168.90 μg/L. The difference between different years was statistically significant ( H = 107.09, P < 0.001). A total of 3 336 cases of thyroid gland examination were conducted in children, including 33 cases of thyroid enlargement, with a goiter rate of 0.99%. There was a statistically significant difference between different years (χ 2 = 15.00, P < 0.001). Conclusion:From 2019 to 2021, children aged 8 to 10 and pregnant women in Xining City are at an appropriate level of iodine, and the achievements in prevention and treatment of iodine deficiency disorders still need to be continuously consolidated.

Objective: To investigate the self-monitoring blood pressure behavior and its influencing factors among residents in Jiangsu Province, so as to provide the basis for strengthening proactive blood pressure monitoring among residents. Methods: Permanent residents aged 35-75 years in six counties (cities, districts), Jiangsu Province, were selected using the stratified cluster sampling method in 2023. Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model. Results: A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors. Conclusions Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

Soil cadmium pollution can adversely affect the cultivation of the ornamental plant, Coleus scutellarioides. Upon cadmium contamination of the soil, the growth of C. scutellarioides is impeded, and it may even succumb to the toxic accumulation of cadmium. In this study, we investigated the effects of arbuscular mycorrhizal fungi (AMF) on the adaptation of C. scutellarioides to cadmium stress, by measuring the physiological metabolism and the degree of root damage of C. scutellarioides, with Aspergillus oryzae as the test fungi. The results indicated that cadmium stress increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and the content of malondialdehyde (MDA) and proline (Pro) within the cells of C. scutellarioides, but inhibited mycorrhizal infestation rate, root vigour and growth rate to a great degree. With the same cadmium concentration, the inoculation of AMF significantly improved the physiological indexes of C. scutellarioides. The maximum decrease of MDA content was 42.16%, and the content of secondary metabolites rosemarinic acid and anthocyanosides could be increased by up to 27.43% and 25.72%, respectively. Meanwhile, the increase of root vigour was as high as 35.35%, and the DNA damage of the root system was obviously repaired. In conclusion, the inoculation of AMF can promote the accumulation of secondary metabolites, alleviate root damage, and enhance the tolerance to cadmium stress in C. scutellarioides.
