Objective Objective To analyze the potential spatial factors affecting the genetic differentiation of Oncomelania hupensis robertsoni in Yunnan Province. Methods A total of 13 administrative villages were selected from schistosomiasis-endemic areas of Yunnan Province as O. hupensis snail sampling sites. At least 200 snails were collected in each site, and the spatial variable data of each site were recorded, including longitude, latitude and altitude. Thirty active and Schistosoma japonicum uninfected O. hupensis snails were selected from each sampling site by means of the crawling method and the cercarial shedding method. Genomic DNA was extracted from O. hupensis snails. Following PCR amplification, purification of PCR amplification products and sequencing, the gene sequences of O. hupensis snail samples were spliced and edited using the DNAstar software and the NCBI database to yield the complete mitochondrial sequences of O. hupensis snails at each sampling site, and the mitochondrial genetic distance matrix of O. hupensis robertsoni was calculated at each sampling site. The geographical coordinates of each sampling site were marked using the software ArcGIS 10.2, and the straight-line geographical distance between each sampling site was calculated. The altitude difference, longitude difference and latitude difference between each sampling site were calculated using the Excel software, and the correlation between the mitochondrial genetic distance matrix of O. hupensis robertsoni and each spatial variable matrix was examined by using the Mantel test at 13 sampling sites in Yunnan Province. Results Among the 13 O. hupensis snail sampling sites in Yunnan Province, the largest mitochondrial genetic distance of O. hupensis robertsoni snail populations was seen between Anding Village, Nanjian Yi Autonomous County and Caizhuang Village, Midu County (26.244 2), and the largest geographical distance was seen between Dongyuan Village, Gucheng District and Cangling Village, Chuxiong County (272.64 km). The highest altitude difference was seen between Anding Village, Nanjian Yi Autonomous County and Dongyuan Village, Gucheng District (1 086.10 m), and the largest longitude difference was found between Qiandian Village, Eryuan County and Cangling Village, Chuxiong County (1.86°), while the largest latitude difference was measured between Leqiu Village, Nanjian Yi Autonomous County and Dongyuan Village, Gucheng District (1.81°). In addition, the mitochondrial genetic distance of O. hupensis robertsoni snail populations was positively correlated with altitude at 13 snail sampling sites in Yunnan Province (r = 0.542 8, P < 0.001), and showed no significant correlations with geographical distance (r = 0.093 4, P > 0.05), longitude (r = −0.199 5, P > 0.05) or latitude (r = 0.205 7, P > 0.05). Conclusion Altitude may be a potential spatial factor affecting the genetic differentiation of O. hupensis robertsoni in Yunnan Province.

Objective To compare the clinical efficacy, safety, and patient’ prognosis of catheter-directed thrombolysis (CDT) via anterior tibial vein and popliteal vein approaches in the treatment of acute lower extremity deep vein thrombosis (DVT). Methods A retrospective analysis was conducted on the clinical data of 195 patients diagnosed with acute mixed lower extremity DVT and treated with CDT in the Department of Interventional and Vascular Surgery, Affiliated Hospital of Nantong University from January 2020 to December 2023. Patients were divided into an observation group (anterior tibial vein approach, n=97) and a control group (popliteal vein approach, n=98) according to the puncture route. Baseline data, thrombolysis-related indices (urokinase dosage, coagulation function indices), efficacy measures (degree of thrombus dissolution, leg circumference difference, visual analogue scale [VAS] score, venous clinical severity score [VCSS]), recovery parameters (time to ambulation, length of hospital stay), complication rates, and long-term prognosis measures (Villalta score, incidence of post-thrombotic syndrome [PTS]) were compared between the two groups. Results There was no statistically significant difference in urokinase dosage and levels of coagulation function indices between the two groups. Postoperatively, the leg circumference difference at 15 cm below the knee, VAS score, and VCSS score were significantly lower in the observation group than in the control group (P=0.001). The observation group had higher grade Ⅲ dissolution rates in the popliteal and anterior tibial veins compared to the control group (P<0.05), while differences of dissolution rates in the iliac and femoral veins were not statistically significant. The observation group had shorter length of hospital stay and earlier ambulation times than the control group (P=0.001). There were no significant differences in complication rates, Villalta scores, or PTS incidence between the two groups. Conclusions CDT via the anterior tibial vein puncture approach for acute mixed lower extremity DVT is superior to the popliteal vein approach in promoting resolution of lower extremity swelling, alleviating pain, improving venous clinical symptoms, and achieving higher thrombus dissolution rates in the popliteal and anterior tibial veins. It also enables faster recovery and demonstrates good safety.

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.

The dysfunction of the lysosome and autophagy-lysosome system serves as a driving force for neurodegenerative diseases, metabolic disorders, inflammatory conditions, and other related diseases, closely influencing their onset and progression. Therefore, restoring the function of the lysosome or autophagy-lysosome system has become an increasingly crucial therapeutic strategy in disease management. In this review, we will introduce the lysosomal biogenesis, structure, and function, as well as the biological process of the autophagy-lysosome system. Various diseases closely associated with lysosomal/autophagic dysfunction are also reviewed, emphasizing the significance of targeting the function of the lysosome or autophagy-lysosome system in disease treatment. Finally, we focus on engineered nanomaterials that have the capabilities to restore the function of the lysosome or autophagy-lysosome system, and summarize different strategies and methods for achieving this goal. This review aims to elucidate the latest progress in the field of nanomedicine for lysosomal/autophagic defect-related diseases and inspire the development of innovative and clinically valuable nanomedicines.

Sonodynamic therapy (SDT) can potentially induce immunogenic cell death in tumor cells, leading to the release of ATP, and facilitating the initiation of an immune response. Nevertheless, the enzymes CD39 and CD73 can swiftly convert ATP into immunosuppressive adenosine (ADO), resulting in an immunosuppressive tumor microenvironment (TME). This study introduced a nanomedicine (QD/POM1@NP@M) engineered to reprogram TME by modulating the CD39/CD73/ADO pathway. The nanomedicine encapsulated sonosensitizers silver sulfide quantum dots, and the CD39 inhibitor POM1, while also incorporating homologous tumor cell membranes to enhance targeting capabilities. This integrated approach, on the one hand, stimulates the release of ATP via SDT, thereby initiating the immune response. In addition, it reduced the accumulation of ADO by inhibiting CD39 activity, which ameliorated the immunosuppressive TME. Upon administration, the nanomedicine demonstrated substantial anti-tumor efficacy by facilitating the infiltration of anti-tumor immune cells, while reducing the immunosuppressive cells. This modulation effectively transformed the TME from an immunologically "cold" state to a "hot" state. Furthermore, combined with the checkpoint inhibitor α-PDL1, the nanomedicine augmented systemic anti-tumor immunity and promoted the establishment of long-term immune memory. This study provides an innovative strategy for combining non-invasive SDT and ATP-driven immunotherapy, offering new ideas for future cancer treatment.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

Objective:To investigate the reference intervals of serum uric acid levels in normal-weight children and analyze the factors influencing these levels.Methods:In this cross-sectional study, clinical data were collected from 7 910 normal-weight children, aged 1 month to 15 years, who underwent health check-ups at the Children′s Hospital of Zhejiang University School of Medicine between August 2013 and August 2023. Data included sex, age, pubertal signs, blood pressure, and serum uric acid levels. The participants were categorized into 4 age groups: 1-<12 months, 1-<6 years, 6-<11 years, and 11-<16 years, and were further analyzed by sex. The P5 and P95 percentiles of uric acid values were defined as the lower and upper limits of the reference interval, respectively. Correlation analysis and partial correlation analysis were used to assess the relationship between uric acid and other variables such as age, body mass index Z value, and Tanner stage. Multivariate linear regression was used to compare uric acid levels across gender and age groups, respectively. Results:Among the 7 910 children, the distribution across age groups was as follows: 562 (317 boys) in 1-<12 months, 4 120 (2 366 boys) in 1-<6 years, 2 357 (1 432 boys) in 6-<11 years, and 871 (536 boys) in 11-<16 years, the uric acid levels in boys were significantly higher than those in girls ( P<0.05). Uric acid levels exhibited a positive correlation with age ( r=0.47 , 0.20, both P<0.001), and a weak positive correlation with BMI Z-scores(both r=0.11, P<0.001). Among participants aged 6-<11 years and 11-<16 years, uric acid levels in boys were positively correlated with Tanner stage ( r=0.10, 0.27, both P<0.05), but no significant correlation was observed in girls (all P>0.05). The uric acid levels were significantly higher in boys than in girls in the 1-<12 months, 1-<6 years and 11-<16 years age groups (all P<0.05), but no significant gender difference was found in the 6-<11 years groups ( P>0.05). Uric acid levels exhibited statistically significant variations among age groups ( P<0.001). The reference intervals of uric acid values were as follows in 1-<12 months age group, 157-335 μmol/L for boys and 160-315 μmol/L for girls; in 1-<6 years age group, 180-359 μmol/L for boys and 180-355 μmol/L for girls; in 6-<11 years group, 190-375 μmol/L; in 11-<16 years age group, 237-480 μmol/L for boys and 218-410 μmol/L for girls. Conclusions:Reference intervals for uric acid varying significantly across different pediatric age groups. Sex, and pubertal development status are closely related to uric acid levels.

Objective:To compare the effectiveness of sacral nerve electric stimulation (SNES) and sacral nerve magnetic stimulation (SNMS) in treating patients with refractory neurogenic bladder (NB).Methods:Forty-six patients with NB after a spinal cord or cauda equina injury were randomly divided into an SNMS group and an SNES group, each of 23. In addition to basic bladder intervention, the SNMS group was treated with SNMS in the sacral 3 (S3) nerve root area once a day for 21 minutes, 5 days a week for 4 weeks. The SNES group received 24h uninterrupted SNES treatment for 4 consecutive weeks. The bladder pressure-volume assessment indexes, voiding diary indexes, and scores on the Chinese version of the Simplified Health Assessment Scale (SF-Qualiveen) were compared between the two groups before and after 4 weeks of treatment.Results:After the treatment, the safe bladder capacity, average daily number of micturitions, average daily single micturition volume, average daily single maximum micturition volume, average daily number of catheterizations, and average daily single maximum catheterization volume of both groups had improved significantly. After the treatment, the maximum intravesical pressure of the bladder (storage period), bladder compliance, average daily single catheterization volume, and SF-Qua-liveen scores of the SNES group had improved significantly. And that group′s average safe bladder capacity, bladder compliance, daily number of micturitions and average daily single catheterization volume were significantly better than the SNMS group′s averages. The SNES group′s average maximum intravesical bladder pressure and average SF-Qualiveen score were also significantly better.Conclusion:Both SNMS and SNES can improve urine storage and voiding for those with refractory NB in the short term, but SNES is clinically more effective and better improves patients′ life quality.

Objective:To examine the differences in the medical quality of elderly Medicare patients in tertiary public hospitals before and after the implementation of the Diagnosis-related Group Prospective Payment System(DRG-PPS), and to explore the establishment of a long-term quality control mechanism.Methods:A total of 62, 321 inpatient first-page records was collected from Beijing Hospital, including 27, 488 cases from January to December 2019 and 34, 833 cases from January to December 2023.Firstly, the two-sample Kolmogorov-Smirnov test was applied to six sample DRG groups to analyze the statistical differences in the intra-group indicators(average per-case cost, average length of stay)among three age groups(young and middle-aged group: 18-65 years old; early elderly group: 66-79 years old; advanced elderly group: 80-99 years old)before and after the DRG-PPS reform of the medical insurance payment system.Secondly, the two-sample Kruskal-Wallis test was used to analyze the statistical differences in the indicators(total cost, medical cost, nursing cost, medical technology cost, pharmaceutical cost, consumable cost, administrative cost, and length of stay)among the three age groups within the same DRG group.Finally, the Conover test was employed for pairwise comparisons of inter-group indicators between the three groups.Results:Through the intra-group analysis of the total cost and average length of stay indicators of different age groups in the six sample DRG groups( n=6, 248), it was found that the differences were statistically significant.( Z-values for total cost in groups 1-3 was 12.69, 15.73, and 11.45, respectively; Z-values for average length of stay were 8.33, 6.73, and 3.69, respectively; all P<0.05), indicating that the DRG-PPS reform was effective in controlling hospitalization costs and length of stay.The inter-group analysis revealed statistically significant differences in total cost, nursing cost, pharmaceutical cost, consumable cost, administrative cost, and length of stay( H-values were 22.49, 41.86, 15.61, 200.56, 14.73 and 10.73, respectively; all P<0.05; ), suggesting that there were statistically significant differences in cost control among different age groups in the same DRG group.Furthermore, analysis of specific cases revealed that differences in medical costs among different age groups resulted from the combined effects of clinical practice standardization(reflected in the significant reduction of unnecessary examinations and medication)and policy interventions such as volume-based procurement excluding the adverse effects of cost containment on the medical quality of elderly patients in the six sample patient groups.No substantial rise was observed in the 31-day readmission rate, indicating that admission splitting was unlikely to have occurred. Conclusions:The implementation of the DRG-PPS contributed to cost efficiency in the sample hospital.By establishing a long-term quality control mechanism focused on DRG groups with significant cost reductions in elderly patients, abnormal cost-control behaviors can be effectively identified, and high-quality development of the hospital can be achieved while ensuring healthcare quality for elderly patients.

BackgroundAlcohol dependence patients are prone to relapse after their attempts to quit drinking, which poses a considerable threat to their physical and mental health and creates a heavy burden on their families. Currently, empowerment education is increasingly being utilized in the rehabilitation management of chronic diseases, but there remains a striking lack of empirical research on the application of "Internet +" empowerment education based on timing it right in alcohol dependence patients. ObjectiveTo explore the impact of "Internet +" empowerment education based on timing it right on patients with alcohol dependence, in order to maximize the reduction in relapse rates, craving for alcohol and severity of anxiety symptoms. MethodsA total of 120 patients who were hospitalized in the Department of Addiction Medicine, Hebei Provincial Mental Health Center from May 2022 to April 2023 and met the diagnostic criteria for alcohol dependence in the International Classification of Diseases, tenth edition (ICD-10) were enrolled, and they were classified into study group (n=62) and control group (n=58) using random number table methods. Both groups received standard medication and routine care. Additionally, study group underwent a 6-month "Internet +" empowerment education based on timing it right. At baseline, all subjects were assessed using Penn Alcohol Craving Scale (PACS) and Self-rating Anxiety Scale (SAS). Three months and six months after intervention, assessments were conducted using PACS, SAS and Michigan Alcoholism Screening Test (MAST). ResultsThe relapse rates after three and six months of intervention were both lower in study group than those in control group, with statistically significant differences (χ2=8.575, 8.828, P<0.01). ANOVA with repeated measures on PACS total score and scores of each item revealed a significant time effect, group effect and time×group interaction effect (F=159.714~837.751, 84.645~393.606, 24.302~137.896, P<0.01). And significant time effect, group effect and time×group interaction effect were also reported on SAS scores (F=166.237, 65.325, 24.724, P<0.01). Conclusion"Internet +" empowerment education based on timing it right may help reduce relapse rates, alcohol cravings and severity of anxiety symptoms among patients with alcohol dependence.
