OBJECTIVE To explore and establish a full-cycle management model for drug traceability codes that aligns with national policy requirements and the practical needs of healthcare institutions， thereby enhancing the refinement of drug management and the level of medication safety. METHODS A tripartite strategy integrating “hardware deployment， system transformation， and process re-engineering” was adopted. This involved the introduction of intelligent identification devices （personal digital assistant， high-definition industrial reader）， the modification of the hospital information system interface， and the re-engineering of workflows （drug warehousing， dispensing and distribution， drug withdrawal， uploading to the insurance platform） to achieve comprehensive， informatized collection and association of drug traceability codes throughout all stages. RESULTS A full-cycle management model for drug traceability codes was successfully established， realizing the goals of making drugs “traceable to their source， trackable in their distribution， and accountable in their responsibility”. The patient waiting time for medication dispensing before and after the implementation was [3.08（1.67，5.58）] min and [3.28（1.77，5.98）] min， respectively. Among them， the patient waiting time under the pre-preparation mode was [3.60（2.13，6.35）] min and [3.50（2.03，6.30）] min， respectively； the patient waiting time under the real-time mode was [2.05（0.83，4.03）] min and [2.78（1.18，5.38）] min， respectively； the number of dispensing errors was 3， 0， respectively； the staffing of relevant positions had not been increased. CONCLUSIONS The drug traceability code management model constructed from a full-cycle perspective effectively meets national policy requirements. It provides data support for refined hospital management and offers solid technical and procedural safeguards for ensuring patient medication safety and strengthening medical insurance fund supervision， demonstrating practical value.

Objective To develop a tool for assessing the needs for care services for adults with disabilities in welfare institutions,and formulate criteria for classifying care needs.Methods Based on the theory of the International Classification of Functioning,Disability and Health,the core contents of domestic and international care service assessment standards were analysed,and the first draft of the assess-ment tool was formed integrating with the current practice of welfare institutions.A total of eleven experts in the field of care services validated the first draft,and the assessment tool was revised according to the experts'opin-ions.From May to June,2024,340 adults with disabilities from Second Social Welfare Institute of Shanghai were graded to analyze the reliability and validity of the assessment tool.And then,1 046 subjects from Second Social Welfare Institute of Shanghai were graded using the assessment tool,and the scoring intervals for the five levels of care were determined using cluster analysis.Results The assessment tool included four first-level dimensions,eleven second-level dimensions,39 third-level dimen-sions and 43 indicators.The coefficients of variation of each dimension and indicator were less than 0.25 for ex-pert validation,while the average score of the importance of each indicator was above 4.63,with a full score rate more than 0.86.The overall Cronbach's α coefficient was 0.956,the test-retest reliability was 0.997,and the con-tent validity index of each indicator was 0.83 to 1.00.The exploratory factor analysis extracted four common fac-tors,with a cumulative variance contribution of 86.679%;the loading coefficients of indicators were 0.675 to 0.878,and the correlation coefficients among the dimensions were 0.325 to 0.476.Cluster analysis determined the level of institutional care needs as level 1(severe),level 2(medium-heavy),level 3(medium),level 4(light-moderate),and level 5(light).Conclusion The needs assessment tool for care services for adults with disabilities in welfare institutions developed in this study is good in reliability and validity,and can be used in guiding the care services provided for people with disabilities more efficient and targeted.

Amoenucles A-F (1-6), six previously undescribed nucleoside derivatives, and two known analogs (7 and 8) were isolated from the culture of Aspergillus amoenus TJ507. Their structures were elucidated through spectroscopic analysis, single-crystal X-ray crystallography, and chemical reactions. Notably, 3 and 4 represent the first reported instances of nucleosides with an attached pyrrole moiety. Of particular significance, the absolute configuration of the sugar moiety of 1-4 was determined using nuclear magnetic resonance (NMR), electric circular dichroism (ECD) calculations, and a hydrolysis reaction, presenting a potentially valuable method for confirming nucleoside structures. Furthermore, 1, 2, and 5-8 exhibited potential tumor necrosis factor α (TNF-α) inhibitory activities, which may provide a novel chemical template for the development of agents targeting autoimmune and inflammatory diseases.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To observe and analyze the clinical phenotype and genetic characteristics of COL2A1 and COL11A1 de novo mutation (DNM) related Stickler syndrome type Ⅰ and Ⅱ patients. Methods:A family-based cohort study. From December 2023 to November 2024, 4 patients (all probands) with Stickler syndrome diagnosed by clinical and genetic testing in Department of Ophthalmology of People's Hospital of Ningxia Hui Autonomous Region and their parents (8 cases) were included in the study. The patients came from 4 unrelated families. A detailed medical history was taken, and the patients underwent best-corrected visual acuity (BCVA), refraction, and fundus color photography examinations. Systemic examinations included the oral and facial regions, skeletal, joints, and hearing. Peripheral venous blood samples were collected from the patients and their parents, and genomic DNA was extracted. Whole-exome sequencing was used to screen for pathogenic genes and their loci, which were then validated by Sanger sequencing and combined with segregation analysis in the families to identify candidate gene mutation sites. The candidate variants were assessed for pathogenicity according to the American College of Medical Genetics and Genomics (ACMG) criteria and guidelines for the classification of genetic variants. Additionally, cross-species conservation analysis was performed to determine the evolutionary conservation of wild-type amino acids, and protein three-dimensional modeling techniques were used to characterize the spatial conformational changes of the variant proteins and the alterations in their local hydrogen bond networks.Results:Among the 4 patients, there were 2 males and 2 females; their ages ranged from 3 to 12 years. There were 2 cases of Stickler syndrome type Ⅰ (proband of families 1 and 2) and 2 cases of type Ⅱ (proband of families 3 and 4). The diopters ranged from -8.00 to-18.00 D. BCVA ranged from no light perception to 0.6 -. There were 2 cases each of vitreous membrane-like and "bead-like" opacity. Three cases showed peripapillary atrophy arcs and leopard pattern changes in the retina; one case had bilateral retinal detachment with a large macular hole in the left eye, which had previously been treated with vitrectomy surgery. One case had bilateral sensorineural hearing loss. There were 3 cases of simple micrognathia; one case had a flat nasal bridge, short nose, midface depression, and micrognathia. Two cases had excessive elbow joint extension. The phenotypes of the parents of the 4 patients were normal. Genetic testing results revealed that the probands of families 1 and 2 carried COL2A1 gene c.85+1G>C (M1) splice site variant and c.3950_3951insA (p.M1317Ifs*48) (M2) frameshift variant, respectively; the probands of families 3 and 4 carried COL11A1 gene (NM_001854.4) c.2549 G>T (p.G850V) (M3) missense variant and c.3816+6T>C (M4) splice site variant, respectively. The parents did not carry the related gene variants. Among them, M2, M3, and M4 are newly reported DNM. According to the ACMG guidelines, they were all considered likely pathogenic. The cross-species conservation analysis results showed that the wild-type amino acid of the COL11A1 gene M3 missense variant was highly conserved across multiple different species. Protein local structure modeling analysis revealed that the COL2A1 gene M2 frameshift variant and the COL11A1 gene M3 missense variant significantly altered the tertiary structure conformation of the protein, leading to abnormal spatial arrangement and hydrogen bond network in the key functional domains Conclusion:The COL2A1 gene M1 splice site variant, M2 frameshift variant, and the COL11A1 gene M3 missense variant, M4 splice site variant are respectively the potential pathogenic genes for families 1, 2, and families 3, 4; leading to the onset of Stickler syndrome type Ⅰ in families 1 and 2, and type Ⅱ in families 3 and 4.

Objective To investigate the predictive value of serum lipoprotein-associated phospholipase A2(Lp-PLA2)and homocysteine(Hcy)combined with white matter hyperintensities(WMH)for cognitive impairment in patients with cerebral small vessel disease(CSVD).Methods A total of 240 patients with CSVD were selected.According to the Montreal Cognitive Assessment(MoCA)scale,all subjects were divided into the non-cognitive impairment group(MoCA≥26 points,120 cases)and the cognitive impairment group(MoCA＜26 points,120 cases).Paraventricular white matter high signal(PWMHs)and deep white matter high signal(DWMHs)were scored by Fazekas scale.The sum of the two parts was the total score,and the severity of DWMHs was graded by the score.The basic information,serum Lp-PLA2,Hcy level and severity of WMH were compared between the two groups.Logistic regression was applied to analyze influencing factors of cognitive impairment in CSVD patients.The predictive value of serum level of Lp-PLA2 and Hcy and WMH for cognitive impairment in CSVD patients was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the non-cognitive impairment group,patients of the cognitive impairment group were older,had higher serum levels of Lp-PLA2 and Hcy,and had more severe of WMH(P＜0.05).Results of Logistic regression analysis showed that serum Lp-PLA2,Hcy levels and severity of WMH were influencing factors for cognitive impairment of patients with CSVD(P＜0.05).The results of ROC curve analysis showed that the area under the curve of serum Lp-PLA2,Hcy level combined with severity of WMH predicting cognitive impairment in patents with CSVD was 0.812,the sensitivity was 81.7%and the specificity was 71.7%(P＜0.05).Conclusion Patients with cognitive impairment caused by CSVD have higher serum levels of Lp-PLA2 and Hcy,and more severe WMH.The combination of the three has a relatively high predictive value for cognitive impairment in patents with CSVD.

Meningeal metastasis is a kind of serious complications of malignant tumor cells invading the leptomeninges and spreading along the cerebrospinal fluid, whose detection rate is gradually increased with advanced imaging diagnostic techniques. Although traditional intrathecal chemotherapy can prolong the survival of patients with meningeal metastasis, its efficacy is still unsatisfactory. In recent years, new intrathecal injection regimens, targeted drug therapy, and proton radiotherapy have significantly improved the prognosis of some patients with meningeal metastasis; however, these treatment regimens still require high-quality evidence-based medical evidences. This article reviews the recent advance in intrathecal injection, systemic treatments (systemic chemotherapy, molecular targeted therapy and immunotherapy), and radiotherapy of meningeal metastasis in recent years, so as to help selecting treatment regimens for meningeal metastasis in clinical practice.

Objective:To explore the current implementation status and challenges of family doctor contract services (FDCS) from the perspective of contracted residents.Methods:This qualitative study used purposive sampling to select contracted residents from 11 primary healthcare institutions across five cities in China. Semi-structured interviews were conducted from March to December 2024, covering topics such as awareness of contracting, service experience, health needs, service continuity, and policy recommendations. Thematic framework analysis was applied to organize, code, and summarize the data.Results:A total of 25 contracted residents were interviewed (6 men, 19 women; 11 from central urban areas, 14 from suburban or rural towns; 8 with chronic diseases). Three main themes and ten sub-themes emerged: Theme Ⅰ: Pathways to improved service accessibility (optimized chronic disease management, more efficient referrals, and improved health education). Theme Ⅱ: Structural misalignment between supply and demand (limited specialty services despite patient needs, insufficient coverage and public awareness of home-based medical care, imbalanced human resources, and service disruption due to clinician turnover). Theme Ⅲ: Challenges in service awareness and communication mechanisms (information asymmetry and public misperception regarding FDCS, perverse incentives in administrative performance evaluation, and communication barriers in building patient-doctor trust).Conclusions:While FDCS has shown progress in chronic disease management, referral coordination, and health education, structural supply-demand gaps and communication challenges continue to hinder service quality. Improvements in resource allocation and service models are needed to support high-quality development.

This study aims to analyze the screening results and epidemiological characteristics of prostate cancer (PCa) among elderly males in the rural areas of Songjiang, Shanghai City, through the implementation of a preliminary prostate-specific antigen (PSA) screening based on a community-linkage model, and to explore an effective screening approach. A retrospective observational study design was employed to collect data from residents who underwent PSA screening at Songjiang Hospital affiliated to Shanghai Jiao Tong University School of Medicine, in collaboration with multiple community health service centers in Songjiang District, Shanghai City, between June 2022 and June 2024, through free clinics and annual health examinations. Prostate biopsy was recommended for individuals with total PSA (tPSA) levels >10 ng/ml and those with 4 ng/ml≤tPSA≤10 ng/ml and abnormal free-to-total PSA (f/tPSA) ratios. Clinical characteristics of detected PCa patients were analyzed. Follow-up was conducted through phone calls and home visits by family doctors, coupled with enhanced health education. The results indicated that a total of 17 198 residents participated in the screening, among which 2 234 (12.99%) had tPSA levels between 4 ng/ml and 10 ng/ml, and 257 (1.49%) had tPSA levels >10 ng/ml. Ultimately, 417 residents underwent prostate biopsy, with 171 being diagnosed with PCa, yielding a positive biopsy rate of 41.00% and a PCa detection rate of 0.99%. The predominant pathological subtype among PCa patients was adenocarcinoma (168 cases, 98.24%). Of the 146 PCa patients who received treatment, the majority were classified as intermediate or high-risk (124 cases, 84.93%). Furthermore, with the optimization of the screening model, there was a significant increase in the proportion of subsequent outpatient visits. In conclusion, the community-linkage-based PSA screening model demonstrated high effectiveness in screening for PCa among elderly males in the rural areas of Songjiang, Shanghai City. Epidemiological findings revealed that PCa patients in this region are primarily composed of intermediate and high-risk groups, highlighting the need for intensified early screening and health education.
