ObjectiveTo explore the establishment of performance assessment indicators for the classification and grading of public health staff in district-level Centers for Disease Control and Prevention (CDCs), and to provide a basis for such evaluations. MethodsThrough literature review and group interviews, performance evaluation indicators were developed based on competency evaluation. Experts were invited to evaluate the weight of performance evaluation indicators for public health staff from different categories, with the average value used to represent the weight of each indicator. ResultsTwenty-nine experts from universities in Shanghai, municipal CDCs, and district CDCs participated, yielding an expert authority coefficient of 0.86. The performance evaluation indicators for department managers were categorized into three levels, with 4 indicators at the primary level, 16 indicators at the secondary level, and 42 indicators at the tertiary level, while those for general staff included 4 primary indicators, 15 secondary indicators, and 36 tertiary indicators. Significant differences were observed in the weight coefficients of the primary indicators (internal operations, professional work, and learning and growth) between department managers and general staff. The top three secondary indicators for department managers were department management, monitoring and prevention, and level of expertise. For mid-level and senior staff, the top three secondary indicators were monitoring and prevention, level of expertise, and research work. The top three secondary indicators for junior staff were monitoring and prevention, professional expertise, and professional attitude. No significant statistical differences were found among tertiary indicators. ConclusionThe developed performance evaluation indicators are reliable. Staff at different levels and classifications should be evaluated using different performance evaluation standards to accurately reflect individual performance and contributions.

A previous study showed that the length of the foreskin plays a role in the risk of sexually transmitted infections and chronic prostatitis, which can lead to poor quality of sexual life. Here, the association between foreskin length and sexual dysfunction was evaluated. A total of 5700 participants were recruited from the andrology clinic at The First Affiliated Hospital of University of Science and Technology of China (Hefei, China). Clinical characteristics, including foreskin length, were collected, and sexual function was assessed by the International Index of Erectile Function-5 (IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires. Men with sexual dysfunction were more likely to have redundant foreskin than men without sexual dysfunction. Among the 2721 erectile dysfunction (ED) patients and 1064 premature ejaculation (PE) patients, 301 (11.1%) ED patients and 135 (12.7%) PE patients had redundant foreskin, respectively. Men in the PE group were more likely to have redundant foreskin than men in the non-PE group ( P = 0.004). Logistic regression analyses revealed that the presence of redundant foreskin was associated with increased odds of moderate/severe ED (adjusted odds ratio [aOR] = 1.31, adjusted P = 0.04), moderate PE (aOR = 1.38, adjusted P = 0.02), and probable PE (aOR = 1.37, adjusted P = 0.03) after adjusting for confounding variables. Our study revealed a positive correlation between the presence of redundant foreskin and the risk of sexual dysfunction, especially in PE patients. Assessment of the length of the foreskin during routine clinical diagnosis may provide information for patients with sexual dysfunction.

Objective To explore the application value of a novel portable endoscope to perform upper gastrointestinal tract examinations in primary medical units.Methods A total of 532 subjects receiving portable endoscope examination were enrolled for analysis.The primary outcome was the success rate of operation.The secondary outcomes were the operation time,examination results,polyp removal and biopsy pathology results,and the subjective evaluation.Results In 532 cases,2 were withdrawn midway after the endoscope was inserted into the esophagus due to the patients'inability to tolerate the examination.Additionally,6 cases did not undergo examination of the descending part of the duodenum because of serious reactions during the procedure.Ultimately,524 cases successfully completed the upper gastrointestinal examination,and the success rate was 98.5％.The average examination time was(4.7±1.8)min,and the average time for disposal sheath wearing and removing was(4.2±1.4)min.The most common lesions were chronic non-atrophic gastritis(85.1％,451/530),reflux esophagitis(14.7％,78/530)and bile reflux(14.0％,74/530).A total of 10 cases of polyp removal were completed,and the polyp removal rate was 71.4％(10/14).Biopsy pathological diagnosis was completed in 44 cases,and the biopsy rate was 8.3％(44/530).The main discomfort symptoms during the examination were nausea(53.6％,285/532),vomiting(51.1％,272/532),and sore throat(38.5％,205/532),the main discomfort symptoms after the examination were sore throat(27.8％,148/532),nausea(19.5％,104/532),and vomiting(14.7％,78/532).No serious adverse events such as gastrointestinal bleeding,perforation,cardiac or pulmonary complications occurred.Conclusion The novel portable endoscope can safely and effectively complete the diagnosis and treatment of upper gastrointestinal diseases in primary medical units,while saving the decontamination process.However,the incidence of discomfort is high during examinations.Further optimization of the operation methods is needed.

Objective To develop a novel solid-phase extraction(SPE)method based on a functionalized nanofiber membrane for the efficient co-extraction of structurally diverse antibiotics with markedly different physico-chemical properties from source water,and to establish a high-throughput analysis method by coupling this technique with ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).Methods A polydopamine and zirconium(Ⅳ)fumarate metal-organic frameworks(MOF-801)co-modified polyacrylonitrile nanofiber membrane(PDA@PAN/MOF-801 NFMs)was prepared as the SPE adsorbent through hybrid electrospinning and dopamine self-polymerization.Critical SPE and UPLC-MS/MS parameters were optimized,and the method was applied to analyze antibiotic contamination in source water samples from 14 sources of centralized drinking water supply in Suzhou,China,to evaluate the practical application potential of the method.Results The PDA@PAN/MOF-801 NFMs adsorbent demonstrated efficient adsorption of 32 antibiotics from 6 classes through multiple retention mechanisms,including synergistic electrostatic interactions,hydrogen bonding,and π-π interactions.In combination with UPLC-MS/MS,the SPE method we developed enabled high-throughput detection of multiple antibiotics in source water,with limits of detection(LOD)being 0.001-0.05 ng/L and limits of quantitation(LOQ)being 0.005-500 ng/L.Spiked recoveries were 70.14%-111.50%.Intra-day relative standard deviation(RSD)was below 14.12%and the inter-day RSD was below 15.07%.The method demonstrated excellent sensitivity,accuracy,and precision.Conclusion In this study,we successfully developed an efficient analytical method based on a novel nanofiber membrane adsorbent.This approach provides a new technical reference for the high-throughput detection of multiple antibiotics in environmental waters and shows promising potential for practical applications.

Acute ischemic stroke (AIS) is a kind of central nervous system disease that seriously threatens human health and life. Current treatment for AIS is mainly reperfusion. However, the time-sensitive of reperfusion limits its clinical application, and a considerable part of patients within the time window cannot achieve the expected effect after reperfusion; related complications of reperfusion have not been completely solved. So far, some clinical trials have confirmed that neuroprotectants are useful supplements and adjuncts to reperfusion. This paper reviews the recent advance in neuroprotectants combined with reperfusion in AIS to provide references for AIS treatment.

The organization of the brain follows a topological hierarchy that changes dynamically during development. However, it remains unknown whether and how cognitive training administered over multiple years during development can modify this hierarchical topology. By measuring the brain and behavior of school children who had carried out abacus-based mental calculation (AMC) training for five years (starting from 7 years to 12 years old) in pre-training and post-training, we revealed the reshaping effect of long-term AMC intervention during development on the brain hierarchical topology. We observed the development-induced emergence of the default network, AMC training-promoted shifting, and regional changes in cortical gradients. Moreover, the training-induced gradient changes were located in visual and somatomotor areas in association with the visuospatial/motor-imagery strategy. We found that gradient-based features can predict the math ability within groups. Our findings provide novel insights into the dynamic nature of network recruitment impacted by long-term cognitive training during development.

Objective:To evaluate the effect of autologous hematopoietic stem cell transplantation (ASCT) on the treatment of relapsed/refractory multiple myeloma (RRMM) with chimeric antigen receptor T cell (CAR-T) therapy.Methods:A retrospective cohort study. The clinical data of 168 patients with RRMM who underwent CAR-T therapy at the Department of Hematology, Xuzhou Medical University Hospital from 3 January 2020 to 13 September 2022 were analyzed. Patients were classified into a transplantation group (TG; n=47) and non-transplantation group (NTG; n=121) based on whether or not they had undergone ASCT previously. The objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and the levels of CD3, CD4, CD8, CD19, CD56 and natural killer (NK) cells before CAR-T infusion were analyzed by χ2 test, Kaplan-Meier method and independent sample t-test. Results:Among 168 patients with RRMM, 98 (58.3%) were male. The median age of onset was 57 (range 30-70) years. After CAR-T therapy, the ORR of patients was 89.3% (92/103) in the NTG and 72.9% (27/73) in the TG. The ORR of the NTG was better than that of the TG ( χ2=5.71, P=0.017). After 1 year of CAR-T therapy, the ORR of the NTG was 78.1% (75/96), and that of the TG was 59.4% (19/32). The ORR of the NTG was better than that of the TG ( χ2=4.32, P=0.038). The median OS and PFS in the NTG were significantly longer than those in the TG (OS, 30 vs. 20 months; PFS, 26 vs. 12 months; both P<0.05). The CD4 level before CAR-T infusion in the TG was significantly lower than that in the NTG (25.65±13.56 vs. 32.64±17.21; t=-2.15, P=0.034), and there were no significant differences in the counts of CD3, CD8, CD19, CD56, and NK cells between the TG and NTG (all P>0.05). Conclusion:Among patients suffering from RRMM who received CAR-T therapy, patients who did not receive ASCT had significantly better outcomes than those who had received ASCT previously, which may have been related to the CD4 level before receiving CAR-T therapy.

To investigate the prevalence and epidemiological characteristics of diabetic retinopathy (DR) in Yunnan Province, explore its risk factors, and provide a basis for the prevention and treatment of chronic complications of diabetes mellitus (DM). This is a large cross-sectional study, in all, 1 524 DM patients in 16 communities and villages of Yunnan Province who were registered in health service centers were included in this study from August to November 2019. All patients completed a uniform questionnaire, anthropometric measurements, biochemical measurements, and auxiliary examinations. Logistic regression analysis was used to screen the risk factors of DR. The prevalence rates of DR, mild non-proliferative DR (mild-NPDR), and referable DR (RDR) were 16.0% (244/1 524), 4.5% (69/1 524), and 11.5% (175/1 524), respectively. Glycated hemoglobin A 1c (HbA 1c)≥7.0% was the risk factor of mild-NPDR ( OR=1.872, 95% CI 1.055-3.323) and RDR ( OR=4.821, 95% CI 2.917-7.969). Blood pressure≥130/80 mmHg (1 mmHg=0.133 kPa) was the risk factor of mild-NPDR ( OR=1.933, 95% CI 1.112-3.358) and RDR ( OR=1.505, 95% CI 1.063-2.130). In Yunnan Province, 16.0% DM patients had accompanying DR, wherein about 71.7% of them required an ophthalmology referral, and the high incidence of RDR in DM patients was associated with poor control of blood glucose and blood pressure.
