Objective:To analyze the influencing factors of pelvic floor muscle exercise (PFME) compliance in patients with urinary incontinence after laparoscopic radical prostatectomy (LRP) based on the theory of disease uncertainty, and construct a structural equation model, so as to explore the impact mechanisms of disease uncertainty, social support, PFME self-efficacy, and disease coping styles on exercise compliance in patients with urinary incontinence after LRP.Methods:Convenience sampling was used to select 300 postoperative urinary incontinence patients who underwent LRP and PFME at Tenth People's Hospital of Tongji University between June 2023 and June 2024 as study subjects. Patients were assessed using the General Information Questionnaire, PFME Compliance Scale, Mishel Uncertainty in Illness Scale-Adult (MUIS-A), Broome Pelvic Muscle Self-Efficacy Scale (BPMSES), Social Support Rating Scale (SSRS), and Medical Coping Modes Questionnaire (MCMQ). Multiple linear regression analysis was employed to identify factors influencing PFME compliance in patients with urinary incontinence after LRP. Pearson correlation was used to analyze the correlation between PFME compliance and disease uncertainty, self-efficacy, social support, and medical coping styles in patients with urinary incontinence after LRP. AMOS 26.0 software was used for path analysis.Results:A total of 300 questionnaires were distributed, and 282 valid questionnaires were collected, with a valid response rate of 94.00% (282/300). Among 282 patients with urinary incontinence after LRP, the PFME Compliance Scale, MUIS-A, BPMSES, SSRS, and MCMQ scores for confrontation, avoidance, and resignation coping styles were (11.92±2.60), (72.37±14.56), (166.98±17.10), (50.69±6.73), (14.46±2.56), (14.12±2.91), and (12.32±2.58), respectively. PFME compliance showed negative correlations with MUIS-A scores and resignation coping style ( r=-0.559, -0.606; P<0.01), while exhibiting positive correlations with PFME self-efficacy, social support and confrontation coping style ( r=0.494, 0.539, 0.118; P<0.05). Bootstrap mediating analysis showed that disease uncertainty not only directly affected PFME compliance in patients with urinary incontinence after LRP, but also indirectly affected PFME compliance through three pathways: disease uncertainty→ PFME self-efficacy→ PFME compliance, with an effect value of -0.147 [95% CI (-0.250, -0.085) ], accounting for 18.1% of the total effect; disease uncertainty→ resignation coping style→ PFME compliance, with an effect value of -0.184 [95% CI (-0.270, -0.115) ], accounting for 22.7% of the total effect; disease uncertainty→ social support → PFME compliance, with an effect value of -0.173 [95% CI (-0.300, -0.070) ], accounting for 21.4% of the total effect. The indirect total effect constituted 62.2% of the total effect. Conclusions:Patients with urinary incontinence after LRP have low PFME compliance. Disease uncertainty not only directly affects PFME compliance, but also indirectly affects it through PFME self-efficacy, social support, and coping styles.

Objective:To present an evaluation indicator system for access to cancer screening services.Methods:The evaluation indicator pool was constructed through a scoping review. The theoretical framework was constructed based on the multi-source indicators, and the qualitative expert consultation method was employed to form the initial version of the three-level evaluation indicator system. Delphi expert consultation method was conducted in two rounds to evaluate the relevance, importance, and availability of the proposed evaluation indicator system. The expert positive coefficient, authority coefficient, coordination degree of expert opinions, and concentration of expert opinions were subjected to analysis. Subsequently, the three-level evaluation indicator system for access to cancer screening services was adjusted and determined based on the boundary value method and the open opinions of experts. Finally, the combination weight method was employed to determine the weight.Results:The initial version of the indicator system comprised 3 primary (first-level) indicators, 11 secondary (second-level) indicators, and 46 tertiary (third-level) indicators. Delphi expert consultation was conducted for the initial version, and 17 experts ultimately completed it, exhibiting a positive coefficient of 100% and an authority coefficient of 0.87. In comparison to the initial round of consultation, Kendall's W coefficient ranges (0.15-0.43, all P<0.05) of relevance, importance, and availability scores for each tertiary indicator in the second round exhibited an improvement. The analysis of the importance dimension indicates that expert opinions are also more concentrated, as evidenced by an increase of 8.5% and 7.0% in the proportion of the tertiary indicators with an arithmetic mean above 8 and a full mark ratio above 0.5, respectively. The final evaluation indicator system comprises three primary indicators, with the weights of structure evaluation, process evaluation, and outcome evaluation being 0.338, 0.378, and 0.285, respectively. It also comprises 11 secondary indicators and 45 tertiary indicators. Conclusions:The evaluation indicator system developed in this article can be an effective evaluation tool for quantitative comparison of access to cancer screening services across different populations, cancer types, and before and after intervention. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

Objective:To quantitatively analyze the death and disability-adjusted life years (DALY) attributed to high level serum LDL-C in Chinese population in 2017.Methods:Data were obtained from the '2017 Global Burden of Disease Study (GBD2017)’. Population attributable fraction (PAF), number and rate of deaths and DALY attributable to high LDL-C were used to describe the burden of disease by gender, age groups, diseases and provinces in China. Both rates on mortality and DALY were standardized by GBD world population.Results:In 2017, 862 759 deaths were caused by high level serum LDL-C in China, that accounting for 8.25 % of the total deaths. Of the attributable deaths, 705 355 (81.76 %) persons died from ischemic heart disease (IHD), while the remaining 18.24 % from ischemic stroke (IS). High LDL-C accounted for 40.30 % of the total deaths from ischemic heart disease and 18.49 % from ischemic stroke. The highest PAF of death (13.70 %) appeared in Jilin province and the lowest in Zhejiang province (4.65 %). PAF of death was seen higher in females than in males, while both age-standardized rates of mortality and DALY appeared higher in males than in females. High LDL-C attributed mortality rate appeared as 61.08/100 000 after standardization in Chinese population. High LDL-C attributed DALYs were 18.16 million person years, among which 76.76 % were caused by IHD (13.94 million person years), with DALY rate as 1285.83/100 000. Among provinces, Heilongjiang showed the highest standardized DALY rate, and Zhejiang the lowest. The PAF, number of deaths, rates on mortality and DALY caused by high LDL-C were high among residents above 70 years old, with the DALY number as 8.56 million person years, highest seen in the age group from 50 to 69 years old. Conclusion:The burden of disease attributed to high level LDL-C was quite high and with gender, age group and interprovincial differences, in China in 2017.

Objective: To analyze the disease burden of pancreatic cancer in China in 1990 and 2017. Methods: Province-specific data in China from the Global Burden of Disease Study (GBD) 2017 were used to describe the change of death status, disease burden of pancreatic cancer in Chinese population by specific province and age groups, including incidence, mortality, disability-adjusted life years (DALY), years of life lost (YLL) due to premature mortality and years lived with disability (YLD) in 1990 and 2017. Meanwhile the incidence, mortality, DALY rate, YLL rate, YLD rate were standardized by the GBD global standard population in 2017. Results: In 2017, the new cases of pancreatic cancer, incidence and age-standardized incidence accounted for 83.6 thousand, 5.92/100 000 and 4.37/100 000 in China, with an increase of 230.94%, 180.45% and 49.88% compared with 1990, respectively. The total number of deaths, mortality and age-standardized mortality appeared as 85.1 thousand, 6.02/100 000, 4.48/100 000, with an increase of 236.08%, 184.80% and 47.51% respectively. The incidence and mortality of pancreatic cancer increased with age and accelerated from the age of 55 to 59 both in 1990 and 2017. The highest incidence and mortality showed in 85-89 years old in 2017 and in 90-94 years old in 1990. The standardized DALY rate of pancreatic cancer increased from 71.00/100 000 in 1990 to 94.32/100 000 in 2017, increased by 32.84%. The standardized YLL rate increased from 70.39/100 000 to 93.42/100 000, increased by 32.72%. The standardized YLD rate increased from 0.62/100 000 to 0.90/100 000, increased by 45.80%. In terms of age distribution, DALY rate, YLL rate and YLD rate of pancreatic cancer basically showed an increasing trend with age in 1990 and 2017. In 2017, Jiangsu (7.61/100 000), Shanghai (7.52/100 000) and Liaoning (6.84/100 000) ranked the top three provinces in terms of standardized mortality. Compared with 1990, Henan (104.28%), Sichuan (94.02%) and Hebei (90.39%) saw the fastest increase in standardized mortality. Conclusions The incidence, mortality and disease burden of pancreatic cancer in China increased significantly from 1990 to 2017. Prevention and control measures should be strengthened to reduce the disease burden of pancreatic cancer.

Our previous studies indicate that phosphatidylinositol 4-kinase IIα can promote the growth of multi-malignant tumors via HER-2/PI3K and MAPK pathways. However, the molecular mechanisms of this pathway and its potential for clinical application remain unknown. In this study, we found that PI4KIIα could be an ideal combinatorial target for EGFR treatment via regulating EGFR degradation. Results showed that PI4KIIα knockdown reduced EGFR protein level, and the expression of PI4KIIα shows a strong correlation with EGFR in human breast cancer tissues (r = 0.77, P < 0.01). PI4KIIα knockdown greatly prolonged the effects and decreased the effective dosage of AG-1478, a specific inhibitor of EGFR. In addition, it significantly enhanced AG1478-induced inhibition of tumor cell survival and strengthened the effect of the EGFR-targeting anti-cancer drug Iressa in xenograft tumor models. Mechanistically, we found that PI4KIIα suppression increased EGFR ligand-independent degradation. Quantitative proteomic analysis by stable isotope labeling with amino acids in cell culture (SILAC) and LC-MS/MS suggested that HSP90 mediated the effect of PI4KIIα on EGFR. Furthermore, we found that combined inhibition of PI4KIIα and EGFR suppressed both PI3K/AKT and MAPK/ERK pathways, and resulted in downregulation of multiple oncogenes like PRDX2, FASN, MTA2, ultimately leading to suppression of tumor growth. Therefore, we conclude that combined inhibition of PI4KIIα and EGFR exerts a multiple anti-tumor effect. Dual inhibition of EGFR at protein and activity level via combinatorial blocking of PI4KIIα presents a novel strategy to combat EGFR-dependent tumors.
