Immune-stimulating antibody drug conjugate (ISAC) can not only effectively solve the defects of stimulator of interferon genes (STING) agonists by coupling antibodies with STING agonists through the targeting of antibodies, but also play a synergistic role with antibodies to further improve the efficacy of STING agonists. This review first provides a concise overview of the current research landscape of ISACs and STING agonists, systematically elaborates on evolving trends in STING agonist development, and subsequently summarizes the mechanistic advances in STING ISAC research. Special emphasis is placed on representative STING ISAC candidates in preclinical/clinical development. Finally, the future directions of STING ISACs are critically discussed with perspectives and recommendations, aiming to provide theoretical insights and practical guidance for future investigations.

The high incidence of bleeding after peripherally inserted central catheter (PICC) catheterization increases the risk of puncture site infection and unplanned extubation. Hemostatic dressings should be used in the early stages of catheterization to reduce blood infiltration. However, new hemostatic dressings have various types and advantages, which makes them difficult to choose dressings for medical staff. This paper introduces the types and hemostatic characteristics of novel functional hemostatic dressings, reviews the hemostatic mechanism and hemostatic effect of chitosan, cyanoacrylate gum, alginate, gelatin sponge and oxycellulose dressings in PICC puncture respectively, and prospects the development of new functional hemostatic dressings. It is expected that future hemostatic dressings will move towards multifunctionality and compositeness.

Objective To compare the early clinical efficacy of arthroscopic bridge suture combined with strengthening thread fixation for posterior cruciate ligament(PCL)tibial insertion avulsion frac-tures and traditional open double-row anchor suture fixation,and to explore a safe,effective,and min-imally invasive reduction and fixation method for PCL tibial insertion fractures in knee joint under ar-throscopy.Methods This study was a retrospective study.Sixty patients with PCL tibial insertion frac-tures(Meyers&McKeever types II-IV)and admitted to the Department of Orthopedics of Kunming Hospital of Traditional Chinese Medicine between June 2021 and June 2023 were included,and ran-domly divided into a traditional group(age:39.56±3.24 years,male/female:16/14)and a minimally in-vasive group(age:40.32±4.38,male/female:18/12),each of 30,according to their admission or-der.All patients were of Grade III positive in the drawer test before surgery.The traditional group un-derwent posterior medial inlay incision,reduction under direct vision and double-row anchor suture fix-ation,while the minimally invasive group underwent reduction under total arthroscopy,suture-bridge suture at the tendon-bone junction of PCL,and one anchor suture placed at the femoral insertion of PCL,with the anchor suture line serving as the reinforcing suture.Then,the anchor and suture-bridge suture lines were respectively pulled into the two tunnels behind the tibia from the front and then pulled out from the front of the tibia,and the reinforcing suture was knotted in front of the tib-ia.The bridge suture line was fixed in front of the tibia with an external row anchor.Six months after surgery,both groups were evaluated the efficacy using the posterior drawer test and Lysholm score.Re-sults At the follow-up six months after the surgery,both groups had good fracture healing,with one wound infection and delayed healing in the traditional group and total one-stage heal in the other group.According to the physical examination 6 months after surgery,all were negative in the posterior drawer test,except one of degree II positive in the traditional group.Moreover,the average Lysholm score of the traditional group increased from 65.23±3.48 before surgery to 87.64±4.58 points after surgery(P<0.05),while that of the minimally invasive group increased from 64.35±2.52 to 86.82±2.58(P<0.05),showing no significant differences between the two groups(P>0.05).Conclusion Both techniques in this study can achieve excellent surgical outcomes in the treatment of posterior cruciate ligament avulsion fractures at the tibial insertion site.

Objective To explore the current status of minor children parenting concerns among young and middle-aged breast cancer patients and investigate the influencing factors based on a random forest model so as to provide references for clinical interventions.Methods A convenience sampling method was used to select breast cancer patients undergoing treatment in our hospital between April and December 2023.A self-designed general information questionnaire,the Chinese version of parenting concerns questionnaire(PCQ),perceived social support scale(PSSS),concern about recurrence scale(CARS),and the brief illness perception questionnaire(BIPQ)were used for the study.A random forest model and the least absolute shrinkage and selection operator(LASSO)were employed to prioritise variables and filtered by significance.The selected variables were then incorporated into the multiple linear regression analysis.Results A total of 260 patients completed the study.The score of minor children parenting concerns of young and middle-aged breast cancer patients was 51.1±6.4.The multiple linear regression analysis,which included variables determined by random forest and LASSO regression(and sorted by the importance of influencing factors),showed that higher disease perception,lower perceived social support,greater concern about cancer recurrence,stage IV tumors,being divorced/widowed,and having more minor children were associated with higher parenting concerns among young and middle-aged breast cancer patients(all P<0.05),accounting for 57.0%of the total variance.Conclusion The minor children parenting concerns in young and middle-aged breast cancer patients are at a moderately high level and are influenced by a variety of factors.Healthcare professionals should develop targeted measures and interventions to reduce the parenting concerns among the patients.

BACKGROUND: Research has indicated that the disease burden of alopecia areata (AA) in China exceeds the global average. Therefore, accurate and updated epidemiological information is crucial for policymakers. In this study, we aimed to comprehensively assess the disease burden of AA in China. METHODS: The following four key indicators were utilized: the prevalence of cases; disability-adjusted life-years (DALYs); the age-standardized prevalence rate (ASPR); and the age-standardized DALY rate (ASDR) of AA according to the Global Burden of Disease (GBD) study 2021. We analyzed the epidemiological burden of AA in China during 2021, examined changes between 1990 and 2021, and performed a Bayesian age-period-cohort analysis to predict trends over the course of the next decade (2022-2030). Additionally, a Gaussian process regression model was applied to estimate the relationship between the gross domestic product (GDP) and the ASPR and ASDR of AA at the provincial level between 1992 and 2021. RESULTS: In 2021, the estimated number of patients with AA in China was approximately 3.49 million (95% uncertainty interval [UI], 3.37-3.62 million); of these patients, 1.20 million (95% UI, 1.16-1.25 million) were male and 2.29 million (95% UI, 2.20-2.37 million) were female. This large number of patients with AA resulted in a total of 114,431.25 DALYs (95% UI, 74,780.27-160,318.96 DALYs). Additionally, the ASPR and ASDR were 224.61 per 100,000 population (95% UI, 216.73-232.65 per 100,000 population) and 7.41 per 100,000 population (95% UI, 4.85-10.44 per 100,000 population), respectively; both of these rates were higher than the global averages. The most affected demographic groups were young and female individuals 25-39 years of age. Slight regional disparities were observed, with the northern and central regions of China bearing comparatively higher burdens. Between 1990 and 2021, the health loss and disease burden caused by AA in China remained relatively stable. The ASPR and ASDR of AA increased with the GDP when the annual GDP was less than 2 trillion Chinese yuan; however, a downward trend was observed as the GDP surpassed 2 trillion Chinese yuan. A slight upward trend in the disease burden of AA in China is predicted to occur over the next decade. CONCLUSIONS AA continues to be a public health concern in China that shows no signs of declining. Targeted efforts for young individuals and females are necessary because they experience a disproportionately high burden of AA.

Objective To explore the protective effect and mechanism of miR-202-5p on acute respiratory distress syndrome(ARDS)-induced lung injury in neonatal rats.Methods Sixty newborn SD rats were randomly divided into six groups:the control group(intraperi-toneal injection of normal saline by tail vein),ARDS group(ARDS model established via intraperitoneal injection of 4 mg/kg lipopolysac-charide by tail vein),ARDS+miR-NC group(ARDS rats receiving 2 mg/kg miR-NC via tail vein injection once every 4 h,with intervention for 12 h),ARDS+miR-202-5p group(ARDS rats receiving 2 mg/kg miR-202-5p via tail vein injection once every 4 h,with intervention for 12 h),ARDS+miR-202-5p+ov-NC group,and ARDS+miR-202-5p+ov-ROCK1 group(ARDS rats receiving 2 mg/kg miR-202-5p once every 4 h,with intervention for 12 h;with 6 × 108 plaque-forming units control or overexpression ROCK adenovirus administered via tail vein 3 days before lipopolysaccharide injection).Real-time quantitative PCR was employed to measure miR-202-5p and ROCK1 mRNA expression in rat lung tissue.Hematoxylin and eosin staining was performed to assess pathological lung injury.The lung tissue wet-to-dry weight ratio was determined to evaluate pulmonary edema.Western blotting was utilized to analyze ROCK1,Toll-like receptor 4(TLR4),phosphorylated-nuclear factor κB(p-NF-κB)p65,and phosphorylated-inhibitor of nuclear factor-κBα(p-IκBα)protein expression in lung tissue.The interaction between miR-202-5p and ROCK1 was validated using dual-luciferase reporter gene experiments.Results miR-202-5p expression was significantly down-regulated in ARDS rat lung tissue,while overexpression of miR-202-5p ameliorated pathological injury and pulmonary edema in ARDS rats.ROCK1 mRNA was upregulated in ARDS rat lung tissue;however,overexpression of miR-202-5p decreased the expression of ROCK1 in lung tissue of ARDS rats,while overexpression of ROCK1 reversed the protective effect of overexpression of miR-202-5p on lung injury in ARDS rats.Furthermore,miR-202-5p overexpression suppressed TLR4,p-NF-κB p65,and p-IκBα protein expression in ARDS rat lung tissue,an effect that was reversed by ROCK1 overexpression.Dual-luciferase reporter gene experiments confirmed that miR-202-5p directly targets ROCK1 mRNA 3'UTR.Conclusion miR-202-5p ameliorates ARDS-in-duced lung injury in neonatal rats through targeted suppression of ROCK1 expression,with the underlying mechanism potentially involving inhibition of ROCK1-mediated TLR4/NF-κB signaling pathway activation.

Objective:To investigate the status of dignity impairment in elderly incontinence-related dermatitis patients, and to systematically analyze the influencing factors in order to provide reference opinions for the formulation of medical strategies by clinical medical staff.Methods:Using the cross-sectional survey method, from April 15 to April 30, 2024, aged incontinence-related dermatitis patients were selected from 37 tertiary comprehensive hospitals in 10 provinces and municipalities, including Zhejiang Province, Sichuan Province, Guangdong Province, etc. by convenient sampling method. The general data questionnaire and Patient Dignity Inventory were used to investigate their current situation.Results:A total of 315 questionnaires were collected, 307 were valid, and the effective rate was 97.5%. Among 307 cases, 146 cases were males, 161 cases were females, aged (71.46 ± 9.35) years old. The incidence of impaired dignity in elderly patients with incontinence-related dermatitis was 49.5%(152/307). The average score of Patient Dignity Inventory was (45.50 ± 20.17). The results of multivariate regression analysis showed that farming ( OR = 2.405, 95% CI 1.108-5.217), individual industrial and commercial households ( OR = 5.680, 95% CI 2.504-12.888), the primary disease were respiratory diseases ( OR = 2.716, 95% CI 1.018-7.246) and nervous system diseases ( OR = 6.117, 95% CI 2.572-14.551) were risk factors for impaired dignity in elderly incontinence-related dermatitis (both P<0.05). Not living alone ( OR = 0.381, 95% CI 0.184-0.790) and self-rated family relationship harmony ( OR = 0.630, 95% CI 0.449-0.882) were protective factors for dignity impairment in elderly incontinence-related dermatitis patients (both P<0.05). Conclusions:There are many factors that affect the dignity of patients with incontinence-related dermatitis in the elderly, and medical staff should comprehensively consider a variety of factors and establish and improve a prevention and management mechanism suitable for the dignity of patients with incontinency-related dermatitis in the elderly.
