Objective To analyze the disease burden and trends of bladder cancer in China and globally from 1992 to 2021.  Methods Using the GBD 2021 database, the incidence, prevalence, mortality, and disability-adjusted life years (DALYs) rates of bladder cancer in China and globally from 1992–2021 were analyzed. Average annual percentage change (AAPC) was calculated using Joinpoint regression. Subgroup analyses by sex and age were conducted, and a Bayesian age-period-cohort (BAPC) model was used to predict trends in age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) for the next 15 years.  Results In 2021, China reported 106 000 new cases (ASIR: 5.14/100 000), 571 000 prevalent cases (age-standardized prevalence rate, ASPR: 26.61/100 000), 43 000 deaths (ASMR: 2.34/100 000), and a DALY rate of 45.31/100 000. From 1992–2021, China showed upward trends in ASIR and ASPR but declines in ASMR and DALYs, while global ASIR, ASMR, and DALYs decreased overall with slow ASPR growth. The peak cases in China and globally were both concentrated in the 65-79 age group, with a significantly higher burden on males than females. In China, smoking-related ASMR and ASDR exceeded global averages and rose, whereas high glucose-related indexes were lower and declined. Projections for 2021–2036 indicated that the global incidence and mortality rates would be rising, but ASIR/ASPR would be declining, while in China, the incidence rate would continue to rise, and the mortality rate will stabilize, with a significant increase in ASIR and a gradual decrease in ASPR.  Conclusion From 1992 to 2021, the incidence of bladder cancer in China has shown a continuous upward trend and is projected to persist in the future, with significant gender and age differences. Particular attention should be given to elderly males aged 85-89. The disease burden of bladder cancer attributable to smoking continues to rise, highlighting the urgent need to strengthen tobacco control policies.

ObjectiveTo investigate the differences in pregnancy outcomes between dichorionic diamniotic （DCDA） twin pregnancies conceived via assisted reproductive technology （ART） and those from spontaneous conception， in order to provide evidence for the perinatal management of ART-conceived DCDA twins. MethodsA retrospective analysis was conducted on the clinical data of 549 DCDA twin parturients. Based on the mode of conception， they were divided into ART group （423 cases） and spontaneous conception group （126 cases）. The baseline characteristics， pregnancy complications and neonatal outcomes were compared between the two groups. ResultsRegarding baseline characteristics， the ART group had higher maternal age， number of previous abortions， proportions of primiparas， proportions of advanced maternal age and greater 24-hour postpartum blood loss， but lower parity and proportion of scarred uterus compared to the spontaneous conception group （P<0.05）. For pregnancy complications， the ART group exhibited higher incidences of hypertensive disorders of pregnancy， placental adhesion， postpartum hemorrhage and a higher application rate of uterine artery ascending branch ligation （P<0.05）. There were no statistically significant differences in neonatal-related indicators between the two groups. After adjusting for confounding factors such as age， number of abortions and parities， ART remained an independent risk factor for hypertensive disorders of pregnancy， placental adhesion and postpartum hemorrhage （P<0.05）， while it did not increase the risk of adverse neonatal outcomes. Further subgroup analysis by gestational age showed that in the late preterm subgroup， the risk of ART-related pregnancy complications remained elevated （P<0.05）. Additionally， neonatal outcomes showed no significant difference between the two groups in both the late preterm and term subgroups. ConclusionART increases the risk of hypertensive disorders of pregnancy， placental adhesion and postpartum hemorrhage in DCDA twin parturients. Clinically， enhanced monitoring of blood pressure during pregnancy and blood loss during delivery and postpartum， along with targeted prevention and management of these complications， are crucial for improving pregnancy outcomes.

Objective To investigate the current status of work readiness and its influencing factors among patients returning to work after lung cancer surgery. Methods A retrospective study was conducted on young and middle-aged postoperative lung cancer patients who were treated at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to September 2023 and returned to their jobs. Data were collected through a general information questionnaire, readiness for return-to-work scale (RRTW), general self-efficacy scale (GSES), and simplified coping style questionnaire (SCSQ). Univariate and multivariate logistic regression analyses were used to explore the factors affecting the work readiness of patients returning to work. Results A total of 219 patients were included, with 59 males and 160 females aged 18-60 years. Among the postoperative lung cancer patients returning to work, 73.1% were in the active maintenance stage of return-to-work readiness with a RRTW score of (17.59±1.48) points, and 26.9% were in the uncertain maintenance stage with a RRTW score of (16.22±1.50) points. Multivariate logistic regression analysis showed that patients aged≤30 years (OR=52.381), employees of enterprises and institutions (OR=7.682), agricultural, pastoral, fishery, forestry laborers (OR=15.665), positive coping (OR=5.043), those with higher self-efficacy (OR=1.157) and engaged in physically demanding work (OR=2.449) had higher return-to-work readiness, while patients with≥2 children (OR=0.055), self-payment (OR=0.044), and those working more than 40 hours per week (OR=0.122) had lower return-to-work readiness. Conclusion The return-to-work readiness of young and middle-aged postoperative lung cancer patients needs to be improved, and occupation, job nature, main coping styles, general self-efficacy and other factors are associated with return-to-work readiness.

Objective To investigate the effect of midazolam on neuronal damage in ischemic stroke （IS） rats and its regulatory effect on PTEN-induced putative kinase 1 （PINK1）/E3 ubiquitin ligase （PARKIN） signaling pathway. Methods An IS rat model was established using arterial occlusion method. The rats with successful model were randomly divided into IS group, drug-low, medium, high-dose （drug-L, M, H, 30, 60, 90 mg/kg midazolam） groups, drug-H+autophagy inhibitor 3-MA group （90 mg/kg midazolam+30 mg/kg 3-MA）, and rats with only isolated blood vessels were used as sham surgery groups. Each group received corresponding doses of drugs or physiological saline intervention, and the neurological function scoring, brain histopathology, neuronal apoptosis, ultrastructure, and expression of PINK1, PARKIN, microtubule-associated protein 1 light chain 3 （LC3）, and P62 protein in mitochondria were detected. Results Compared with the IS group, the pathological damage of the drug-L group, drug-M group, and drug-H group was improved, and autophagosomes showed an increasing trend, the expression of PINK1, PARKIN, and LC3 proteins increased, the neurological function score, neuronal apoptosis rate, and P62 protein obviously decreased in a dose-dependent manner （P<0.01 or P<0.001）; compared with the drug-H group, the pathological damage in the drug-H+3-MA group increased and autophagosomes decreased, the expression of PINK1, PARKIN, and LC3 proteins decreased, the neurological function score, neuronal apoptosis rate, and P62 protein obviously increased （P<0.001）. Conclusion Midazolam induced mitochondrial autophagy in IS rats by activating the PINK1/PARKIN signaling pathway, neuronal apoptosis was reduced and neuronal damage were improved in IS rats.

Hyaluronic acid (HA) possesses excellent biocompatibility, biodegradability, and non-immunogenicity, and exhibits active targeting capability to receptors such as cluster of differentiation 44 (CD44). Therefore, HA has become an important material for the design and preparation of drug delivery carriers in recent years. HA is rich in functional groups that can be chemically modified, but different modification methods and sites can affect its biological properties. This paper summarizes and discusses the effects of chemical modification on the biological properties of HA based on the formation mechanisms of such properties, as well as the derivatization and characterization methods of HA, so as to provide some reference for rational research on chemical modification of HA.

Objective:To observe the effect of traditional Chinese medicine (TCM) hot ironing on limb function and balance ability in stroke patients with hemiplegia during the recovery period, and to provide more reference schemes for clinical rehabilitation of stroke patients with hemiplegia.Methods:A randomized controlled study was conducted. Stratified random sampling was used to select stroke patients with hemiplegia during the recovery period admitted to the First Affiliated Hospital of Anhui University of Chinese Medicine from June 2023 to January 2024. The patients were divided into a control group and an observation group using the random envelope method. The control group received limb positioning techniques combined with conventional acupuncture intervention, while the observation group received additional TCM hot ironing intervention. Before and after the intervention, the Brunnstrom motor function grading, three-level assessment method, and Activities of Daily Living (ADL) scale were used to evaluate the patients′ limb function, balance function, and daily living ability.Results:Among the 66 patients included, with 33 patients in the control group, includinng 19 males and 14 females, aged (51.02 ± 8.34) years old, and 33 patients in the observation group, including 21 males and 12 females, aged (49.65 ± 8.21) years old. Before the intervention, there were no statistically significant differences in Brunnstrom upper limb motor function, Brunnstrom lower limb motor function, sitting balance, standing balance, and ADL scores between the two groups (all P>0.05). After the intervention, the observation group showed significant improvements in Brunnstrom upper limb motor function (0 cases at levelⅠ, 33 cases at levelⅡor above), Brunnstrom lower limb motor function (1 case at levelsⅠ-Ⅲ, 32 cases at level Ⅳ or above), sitting balance (0 cases at levelsⅠ-Ⅱ, 33 cases at level Ⅲ), and standing balance (1 case at levelsⅠ-Ⅱ, 32 cases at level Ⅲ). The control group showed less improvement in Brunnstrom upper limb motor function (10 cases at levelⅠ, 23 cases at level Ⅱor above), Brunnstrom lower limb motor function (14 cases at levelsⅠ-Ⅲ, 19 cases at level Ⅳ or above), sitting balance (9 cases at levelsⅠ-Ⅱ, 24 cases at level Ⅲ), and standing balance (11 cases at levelsⅠ-Ⅱ, 22 cases at level Ⅲ). The differences between the two groups were statistically significant ( Z values were 9.39-15.51, all P<0.05). The ADL score in the observation group was (80.25 ± 8.89) points, higher than the control group′s score of (69.97 ± 8.17) points, the difference was statistically significant ( t=4.89, P<0.05). Conclusions:TCM hot ironing can effectively improve limb dysfunction, motor function, balance ability, and walking mobility in stroke patients with hemiplegia during the recovery period, thereby enhancing their daily living ability.

Objective Objective To investigate the expression levels of long non-coding RNA HCG11(LncHCG11)and miR-214-5p in pancreatic cancer tissues and their potential molecular regulatory mechanisms.Methods Ten patients with pancreatic cancer admitted between January 2022 and January 2025 were included,and post-operative cancer tissue and paired adjacent tissue samples were collected.Real-time quantitative PCR technology was used to detect the transcription levels of LncHCG11 and miR-214-5p,and the expression level of sirtuin 2(SIRT2)protein was measured by Western blot.The relationship of miR-214-5p with LncHCG11 and SIRT2 was predicted through a biological database.Results Compared with the adjacent non-cancerous tissues,the expression of LncHCG11 and SIRT2 was significantly reduced in pancreatic cancer tissues,while the level of miR-214-5p was significantly increased(P<0.01).In vitro experiments showed that overexpression of LncHCG11 in the Panc1 cell line could upregulate the expression of SIRT2 protein and simultaneously inhibit the proliferative activity of Panc1 cells(P<0.05).Both miR-214-5p and LncHCG11,SIRT2 had binding sites.Conclusion LncHCG11 may act as a competing endogenous RNA to sponge miR-214-5p,releasing its transcriptional inhibition on SIRT2,thereby inhibiting the progression of pancreatic cancer.
