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 explore the influencing factors for implementation of weight management services in primary medical and healthcare institutions, so as to provide references for implementing sustainable services of weight management. Methods: From May to June 2025, Pinghu City, Zhejiang Province was selected as the survey site. Personnel responsible for weight management in primary medical and healthcare institutions were selected as the survey subjects using a combined method of purposive sampling and snowball sampling. Based on the five core domains of the consolidated framework for implementation research (CFIR), a semi-structured interview outline for weight management services in primary medical and healthcare institutions was designed. Original data was collected through face-to-face semi-structured interviews. Interview data was organized and analyzed using framework analysis. Factors affecting weight management services were quantitatively analyzed by referencing CFIR's structural rating criteria. Results: A total of 21 participants completed interviews, covering positions in nutrition, endocrinology, traditional Chinese medicine, general practice, maternal health, and public health. There were 9 males and 12 females. Fifteen participants (71.43%) were aged 35 years and above, 18 (85.71%) held a bachelor's degree or higher, and 15 (71.43%) were frontline medical staff. Fifteen factors affecting weight management services were identified across five domains: innovation, outer setting, inner setting, individuals, and implementation process. Six barrier factors were identified: difficulties in policy implementation, time-consuming interventions, limited incentive measures, lack of professional skills, unclear weight-loss plans and goal setting, and imperfect follow-up and evaluation mechanisms. Three neutral factors were identified: the development and refinement of policies and regulations, the implementation of weight management training, and the optimization of the referral process within integrated healthcare systems (medical alliances / communities). Six facilitating factors were identified: the relatively significant advantages of lifestyle interventions, collaboration and coordination across multiple departments, cooperative communication among different units within the institution, the inherent convenience of primary care settings, a strong sense of professional responsibility, and the establishment of multidisciplinary teams. Conclusions The delivery of weight management services in primary medical and healthcare institutions is influenced by a wide array of factors across multiple domains. It requires policy support, multi-department coordination, a practice-oriented training system, optimized team resource allocation, incentives, and improved professional skills of medical staff to jointly promote long-term implementation.

Most cancers are currently incurable, partly due to abnormal post-translational modifications (PTMs). In this study, we initially used multiple myeloma (MM) as a working model and found that SUMOylation activating enzyme subunit 1 (SAE1) promotes the malignancy of MM. Through proteome microarray analysis, SAE1 was identified as a potential target for bioactive colcemid or its derivative colchicine. Elevated levels of SAE1 were associated with poor clinical survival and increased MM proliferation in vitro and in vivo. Additionally, SAE1 directly SUMOylated and upregulated the total protein expression of p27, leading to LLPS-mediated nuclear export of p27. Our study also demonstrated the involvement of SAE1 in other types of cancer cells, and provided the first monomer crystal structure of SAE1 and its key binding model with colchicine. Colchicine also showed promising results in the Patient-Derived Tumor Xenograft (PDX) model. Furthermore, a controlled clinical trial with 56 MM patients demonstrated the clinical efficacy of colchicine. Our findings reveal a novel mechanism by which tumor cells evade p27-induced cellular growth arrest through p27 SUMOylation-mediated nuclear export. SAE1 may serve as a promising therapeutic target, and colchicine may be a potential treatment option for multiple types of cancer in clinical settings.

Objective:To research the association between exposure to solid fuels for heating and its duration and the risk of respiratory diseases morbidity.Methods:Data from the China Kadoorie Biobank project sited in Pengzhou City, Sichuan Province. Cox proportional hazard regression model was used to analyze the association between exposure to solid fuels for heating and its duration and the risk of total respiratory diseases and the association between exposure to solid fuels for heating and the risk of chronic obstructive pulmonary disease (COPD) and pneumonia among respiratory diseases.Results:A total of 46 082 participants aged 30-79 years were enrolled, with 11 634 (25.25%) heating during the winter, of whom 8 885 (19.28%) used clean fuels and 2 749 (5.97%) used solid fuels, of whom 34 448 (74.75%) did not heat. After controlling for multiple confounding factors, Cox proportional hazard regression model was used, which revealed that compared with clean fuels, unheating could reduce the risk of total respiratory disease ( HR=0.81,95% CI:0.77-0.86), COPD ( HR=0.86,95% CI:0.78-0.95) and pneumonia ( HR=0.80,95% CI:0.74-0.86), respectively. Exposure to solid fuels increased the risk of total respiratory disease ( HR=1.10, 95% CI:1.01-1.20) and were not associated with COPD and pneumonia. Compared with no solid fuel exposure, the risk of total respiratory disease (1-19 years: HR=1.23, 95% CI:1.10-1.37; 20-39 years: HR=1.25, 95% CI:1.16-1.35; ≥40 years: HR=1.26, 95% CI:1.15-1.39) and COPD (1-19 years: HR=1.21, 95% CI:1.03-1.42; 20-39 years: HR=1.30, 95% CI:1.16-1.46; ≥40 years: HR=1.35, 95% CI:1.18-1.54) increased with the length of exposure of solid fuels (trend test P<0.001). Solid fuels exposure for 1-19 years and 20-39 years increased the risk of COPD by 23% ( HR=1.23,95% CI:1.02-1.49) and 16% ( HR=1.16, 95% CI:1.00-1.35). Conclusion:Heating solid fuels exposure increases the risk of total respiratory disease, COPD, and pneumonia.

Objective:To investigate the morbidity of cerebrovascular disease among residents ≥30 years in Pengzhou, Sichuan Province, and analyze the effect of physical activity level on the risk of morbidity of cerebrovascular disease.Methods:From 2004 to 2008, people from Pengzhou, Sichuan Province were randomly selected. All the local people aged 30-79 were asked to receive a questionnaire survey, physical examination, and long-term follow-up to determine the morbidity of cerebrovascular disease. The physical activity level and the morbidity of cerebrovascular disease were described, and Cox proportional hazard regression models were used to evaluate the association of domain-specific physical activity with the risk of morbidity of cerebrovascular disease.Results:In 55 126 participants, there were 5 290 new cases of cerebrovascular disease, with a cumulative incidence of 9.60%. After the adjustment for multiple confounding factors, multivariate Cox proportional hazard regression analysis showed that increased levels of occupational, transportation, and total physical activity reduced the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). The highest group of occupational physical activity level had the lowest risk of cerebrovascular disease, with a hazard ratio ( HR) value of 0.81 (95% CI: 0.75-0.88), the highest group of transportation physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.84 (95% CI: 0.78-0.91), the highest group of total physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.87 (95% CI: 0.80-0.94), compared with the lowest group of corresponding physical activity. No association was found between the household/leisure-time physical activity level and the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Conclusions:In project areas of Pengzhou, Sichuan Province, increased physical activity has been associated with reduced morbidity of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Increased levels of physical activity in adults are encouraged for health benefits.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Objective By analyzing the anti-tumor innovative drug policies text in China,this study aimed to explore the focus and shortcomings of policies related to anti-tumor innovative drugs,and provide the reference for future policy formula-tion and optimization in the field of anti-tumor innovative drug.Methods By accessing the official websites of relevant minis-tries and subordinate institutions such as the Central Committee of the Communist Party of China,the State Council of the People's Republic of China,the National Health Commission of the People's Republic of China,and National Medical Products Administra-tion,and using the keywords"cancer","tumor","anti-tumor drug",and"innovative drug",etc,the national level policies related to the anti-tumor innovative drugs from January 1,2005,to December 31,2022,were collected.Based on a two-dimensional analy-sis framework of policy tools and stakeholders,the collected policy texts were classified,encoded,and statistically analyzed.Results A total of 30 policy texts were involved,and a total of 90 policy codes were generated.There were 24,43,and 23 codes for demand-based policy tools,environmental policy tools,and supply-based policy tools,accounting for 26.67%,47.78%,and 25.56%,respectively.Based on policy tools and stakeholders,a total of 183 codes were generated,with government departments,pharmaceutical enterprises,medical institutions,and patients having 70,36,54,and 23 codes respectively,accounting for 38.25%,19.67%,29.51%,and 12.57%.Conclusions China had the highest proportion of environmental policy tools in the application of innovative anti-tumor drug policies,while supply-oriented and demand-oriented policy tools were underutilized,resulting in an overall imbalance in application;The distribution pattern of stakeholders was not coordinated,with government departments and medical institutions having higher attention than pharmaceutical enterprises and patients..It was necessary to reasonably promote the collaborative application of anti-tumor innovative drug policy tools,scientifically plan the layout of anti-tumor innovative drug policy sub-tools,and balance the interests of all stakeholders to ensure the efficient implementation of the policies.

Objective:To analyze the clinical value of ultrasound monitoring of endometrial thickness in assessing pregnancy rate improvement after estrogen administration following a missed abortion.Methods:A retrospective study was conducted on 86 patients who underwent surgical abortion at Cixi Maternal and Child Health Hospital from January 2022 to June 2023. Based on the treatment received, the patients were divided into two groups: a control group and an observation group, with 43 patients in each group. The control group received only routine postoperative care without any medication, while the observation group received estrogen treatment after surgery. The clinical efficacy, endometrial thickness, intrauterine adhesion and re-pregnancy rate were compared between the two groups.Results:In the observation group, there was significant difference in endometrial thickness in terms of intergroup, group-by-time interaction, and time effect ( Fintergroup =129.49, Finteraction =14.25, Ftime =146.64, all P < 0.001). Intrauterine adhesions were less severe in the observation group compared with the control group ( χ2 = 4.34, P < 0.05). The clinical effective rate was significantly higher in the observation group than in the control group [88.37% (38/43) vs. 69.76% (30/43), Z = 2.35, P = 0.019]. Additionally, the rate of re-pregnancy was significantly higher in the observation group than in the control group [46.54% (20/43) vs. 13.95% (6/43), χ2 = 10.81, P < 0.05]. Conclusion:Patients who have retained abortion can benefit from ultrasound examination to assess endometrial thickness after estrogen administration. This approach significantly enhances endometrial thickness, promotes menstrual recovery, and reduces intrauterine adhesions. It also improves the rate of re-pregnancy and is highly valuable in clinical settings.

Objective To explore the clinical effect and safety of remimazolam combined with alfentanil in painless gastroenteroscopy in elderly patients.Methods 188 elderly patients who were scheduled to undergo painless gastroenteroscopy from October 2021 to February 2023 were selected and divided into group A,group B,group C,and group D by random number table method,with 47 cases in each group.The group A,group B and group C were used remimazolam 0.2,0.3 and 0.4 mg/kg,and alfentanil 3 μg/kg respectively,and the remimazolam 2.5 mg/time was added during the operation.The group D was used propofol 1.5 mg/kg and alfentanil 3 μg/kg,and a single dose of propofol 0.5 mg/kg was added during the operation.The hemodynamics at different time points[3 min before anesthesia administration(T0),immediately after endoscopy(T1),3 min after endoscopy(T2),at the end of examination(T3),at the time of awakening(T4)],anesthesia onset time,sedation success rate,gastrointestinal endoscopy time,awakening time,time to leave the observation room and intraoperative/postoperative complications were compared,and the test results of neurobehavioral cognitive state examination(NCSE)were compared at different times.Results The percutaneous arterial oxygen saturation(SpO2)at T1 and T2 time point were higher than group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the heart rate(HR)and mean arterial pressure(MAP)among group A,group B,group C and group D at each time point(P>0.05).There was no statistically significant difference in SpO2 between group A and group B at each time point(P>0.05).There was no statistically significant difference in the success rate of sedation,gastrointestinal endoscopy examination time and time of leaving the observation room among the four groups(P>0.05),but the onset time of anesthesia in group A was longer than that in group B,group C and group D,and the awakening time in group A and group B was shorter than that in group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in awakening time between group A and group B(P>0.05).The incidence rate of bradycardia in group A and group B was lower than in group D,and the incidence rates of hypoxemia,respiratory depression,hypotension,and dizziness in group A were lower than those in group D,and the incidence rate of injection pain in group A,group B and group C was lower than that in group D,and the differences were statistically significant(P<0.05).After 10 minutes of complete wakefulness,there was no statistically significant difference in the passing rates of calculation ability and the memory tests between group A and group B(P>0.05),but the passing rates of calculation ability and memory test in group A were higher than those in group C and group D,and the differences were statistically significant(P<0.05).Conclusion During painless gastroenteroscopy in elderly patients,the sedative effect of using 0.3 mg/kg remimazolam combined with alfentanil is good,and it has stable hemodynamics,and the occurrence rate of complications such as bradycardia and espiratory depression is low,and the early postoperative cognitive function is recovered well.

Hemorrhagic shock (HS) is one of the leading causes of death among young adults worldwide. Multiple organ dysfunction in HS is caused by an imbalance between tissue oxygen supply and demand, which is closely related to the poor prognosis of patient. Mitochondrial dysfunction is one of the key mechanisms contributing to multiple organ dysfunction in HS, while mitochondrial quality control regulates mitochondrial function through a series of processes, including mitochondrial biogenesis, mitochondrial dynamics, mitophagy, mitochondrial-derived vesicles, and mitochondrial protein homeostasis. Modulating mitochondrial quality control can improve organ dysfunction. This review aims to summarize the effects of mitochondrial dysfunction on organ function in HS and discuss the potential mechanisms of mitochondrial quality control, providing insights into the injury mechanisms underlying HS and guiding clinical management.
