Objective: Blood safety surveillance is a critical measure for the objective assessment of blood quality and enhancing transfusion safety. This study aims to comprehensively understand the current status of blood safety surveillance and management in blood collection and supply institutions in Sichuan Province, systematically analyze existing problems and vulnerabilities, and provide a basis for optimizing management strategies and improving capabilities to ensure blood safety. Methods: The Blood Safety Surveillance questionnaire was designed, covering adverse donor reaction reporting, management of adverse events, and transfusion adverse reaction feedback. An online survey was conducted via Questionnaire Star platform among 21 blood collection and supply institutions in the province, gathering information on management systems, process implementation, and utilization of monitoring data. The collected data were organized and statistically analyzed using Excel. Results: The questionnaire response rate and validity rate were both 100%. Blood collection and supply institutions in Sichuan Province have generally established a blood safety surveillance system and achieved positive outcomes. Regarding adverse events in blood collection and supply, 95.24% (20 institutions) have established reporting procedures, and 66.67% (14) collect information through multiple channels such as internal reports, external reports, and statistical trend feedback. A total of 90.48% (19) institutions regularly summarize and analyze adverse event data, and 85.71% (18) produce reports with improvement recommendations based on this analysis.71.43% (15) institutions implement reward and penalty measures, and 71.43% (15) report underreporting or omission due to accountability or performance concerns. In terms of monitoring adverse blood donation reactions, all blood collection and supply institutions have established full-process management systems.76.19% (16) collect data through multiple approaches, including on-site donation records, voluntary donor reports, and donor follow-ups. Adverse reactions were followed up in 95.24% (20) of institutions with 65% (13) completing follow-ups within 24 hours.80.95% (17) have established investigation procedures, while 66.67% (14) believe underreporting or omission still occurs. All blood collection and supply institutions regularly compile statistics on adverse donation reactions. Of these, 85.71% (18) institutions providing feedback to management departments and 90.48% (19) analyzing the data and making recommendations.76.19% (16) institutions use monitoring data for return donor management and targeted care, and 71.43% (15 stations) incorporate it into management reviews. Regarding adverse transfusion reactions, 95.24% (20) institutions have established and implemented procedures for isolating, recalling, and tracing of problematic blood units. However, only 42.86% (9) have established feedback mechanisms of adverse transfusion reaction with hospitals, and only 19.05% (4) support direct reporting via information systems.47.62% (10) institutions regularly analyze adverse transfusion reaction data, and 19.05% (4) provide feedback and recommendations to relevant hospitals. All blood collection and supply institutions reported challenges in collecting hospital feedback, citing complexities in data collection and reporting processes. Conclusion: Blood safety surveillance systems have been preliminarily established in Sichuan Province. However, further strengthening is still required, including conducting in-depth data analysis and utilization, standardizing the configuration of emergency medications and equipment, and improving feedback mechanisms for adverse transfusion reactions. To improve the overall level of blood safety management, it is recommended to strengthen closed-loop data management, improve feedback mechanisms between blood collection and supply institutions and hospitals, foster a non-punitive reporting culture, and systematically advance the regionalization and standardization of the monitoring system. These efforts will contribute to sustainably improving the overall effectiveness and sustainability of blood safety management.

This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Objective:To investigate the expression of chondroitin sulfate proteoglycan 4 pseudogene 12(CSPG4P12)in the small cell lung cancer(SCLC)tissue,its relationship with immune infiltration,and its effect on cell biological functions,and to clarify its effect in the occurrence and development of SCLC.Methods:The E-GEOD-60052 cohort was obtained by searching the ArrayExpress database for SCLC.The R language Bioconductor package was used to complete data filtering standardization,and 63 samples of SCLC tumor tissues and 7 samples of normal tissues were obtained.The Mann-Whitney U test was used to analyze the difference in CSPG4P12 expression levels between two groups.Pearson correlation analysis was used to evaluate the associations between CSPG4P12 expression levels and 47 immune checkpoint genes.The ESTIMATE algorithm and CIBERSORT algorithm were used to evaluate the correlations between CSPG4P12 expression and tumor immune cell infiltration.A case-control study was used to analyze the clinical data.A total of 230 patients with SCLC were selected as case group,and 230 healthy subjects were selected as control group.The genotyping of CSPG4P12 rs2880765,rs6496932 and rs8040855 was performed using TaqMan-MGB fluorescent probe labeling method.Odds ratio(OR)and 95％confidence interval(CI)were calculated by unconditional Logistic regression model to analyze the association between polymorphic genetic variation of CSPG4P12 gene and the risk of SCLC.The SCLC DMS114 cells were transfected with pUC-57 plasmid(control group)and CSPG4P12 over-expression plasmid(OV-CSPG4P12 group),respectively.The efficiencies of CSPG4P12 over-expression in two groups were verified by real-time fluorescence quantitative PCR(RT-qPCR)method.Cell counting kit-8(CCK-8)method was used to detect the cell proliferation activities of cells in two groups.Transwell chamber assay was used to detect the numbers of migration and invasion cells in two groups,respectively.Hoechst 33342 fluorescence staining was used to observe the cell apoptosis in two groups.Results:The ArrayExpress database E-GEOD-60052 cohort analysis showed that the expression level of CSPG4P12 mRNA in SCLC tissue was decreased compared with normal tissue(P＜0.001).The expression of CSPG4P12 had positive correlations with the immune checkpoint genes including leukocyte associated immunoglobulin like receptor 1(LAIR1)(r=0.47,P＜0.001),tumor necrosis factor(TNF)receptor superfamily member 9(TNFRSF9)(r=0.38,P＜0.01),and TNF superfamily member 9(TNFSF9)(r=0.44,P＜0.001).The ESTIMATE algorithm results showed that the matrix score,immune score and ESTIMATE composite score of the patients in CSPG4P12 low expression group were lower than those in CSPG4P12 high expression group(P＜0.01).The CIBERSORT algorithm results showed that compared with CSPG4P12 high expression group,the infiltration of M0 macrophages in CSPG4P12 low expression group was increased(P＜0.05)and the infiltration of mast cells resting was decreased(P＜0.05).The CSPG4P12 expression level had positive correlations with infiltration of mast cells resting(r=0.35,P=0.03)and mononuclear cell infiltration(r=0.34,P=0.034).In case-control studies,compared with AA genotype,CSPG4P12 rs2880765 AT and TT genotype carriers had a higher risk of SCLC(OR=1.68,95％CI=1.15-2.45,P＜0.01).The stratified analysis showed that genetic variation of rs2880765 A＞T increased the risk of SCLC in the male,younger age group(≤60 years)and smoking subgroups(males:OR=1.86,95％CI=1.18-2.93,P＜0.01;≤60 years:OR=1.73,95％CI=1.11-2.68,P＜0.01;smoking:OR=2.76,95％CI=1.49-5.13,P=0.001).The cell biology experiment showed that compared with control group,the proliferation abilities of the cells in OV-CSPG4P12 group were significantly decreased at 48 and 72 h(P＜0.01),while the number of migration cells at 24 h was significantly decreased(P＜0.01),the number of apoptotic cells at 24 h was increased(P＜0.05)and the number of invasion cells at 48 h was significantly decreased(P＜0.01).Conclusion:CSPG4P12 is lowly expressed in SCLC tumor tissue,which is associated with immune infiltration.The genetic variation of CSPG4P12 rs2880765 A＞T can increase the risk of SCLC,and its over-expression can inhibit cell proliferation,migration and invasion,and promote apoptosis.

Objective:To investigate the effect of polystyrene microplastics(PS-MPs)combined with high-fat treatment on vascular endothelial cells.Methods:Human umbilical vein endothelial cells(HUVECs)were cultured in the DMEM medium containing 5%fe-tal bovine serum.HUVECs were treated with conventional culture,high-fat treatment,and PS-MPs combined with high-fat treatment.The experiment was conducted in the three groups of control group,high-fat treatment group and PS-MPs+high-fat treatment group.CCK-8 assay was used to measure cell viability,F-actin staining was used to observe cell morphological changes,and flow cytometry,scratch assay,and tube formation assay were used to measure the apoptosis,migration,and tube-forming ability of cells.Results:After HUVECs were exposed to the high-fat environment,there was a significant reduction in cell viability,shrinkage of cells,a signifi-cant increase in cell apoptosis,and significant reductions in cell migration and tube-forming ability.Compared with the high-fat treat-ment group,there were no significant changes in cell viability,cell morphology,cell apoptosis,and cell migration ability after PS-MPs combined with high-fat treatment,but the tube-forming ability of cells was further impaired.Conclusion:High-fat treatment will affect cell viability,change cell morphology,and damage vascular endothelial cell function,and PS-MPs combined with high-fat treat-ment can aggravate the damage of vascular endothelial cell function.

Objective:To investigate the role of alkylation repair homolog 5(ALKBH5)-mediated N6-methyladenosine(m6A)modifi-cation in endometrial decidualization.Methods:The mouse models of pregnancy and pseudopregnancy were established,and quantita-tive real-time PCR and Western blot were used to measure the expression pattern of ALKBH5 in the endometrium.The mouse and cell models of artificially induced decidualization were established,and quantitative real-time PCR,Western blot,and immunohistochemis-try were used to measure the expression levels of decidualization-related markers.The EpiQuik m6A RNA methylation quantification kit was used to measure the level of m6A.The mouse and cell models of artificially induced decidualization with interference of ALKBH5 expression were established,and quantitative real-time PCR,Western blot,and immunohistochemistry were used to measure the expression levels of decidualization-related markers,cell proliferation marker molecules,and apoptosis molecules.Flow cytometry was used to measure cell apoptosis rate.Results:In the mouse model of pregnancy,the expression level of ALKBH5 at the uterine em-bryo implantation site was significantly higher than that adjacent to the implantation site,and in the mouse and cell models of artifi-cially induced decidualization,compared with the control group,the induction group had a significant increase in the expression level of ALKBH5 and a significant reduction in the level of m6A.Inhibiting the expression of ALKBH5 led to an increase in the level of m6A,which in turn inhibited the proliferation of stromal cells,induced cell apoptosis,and ultimately impaired the normal process of en-dometrial decidualization.Conclusion:ALKBH5 deficiency leads to an increase in the level of m6A and decidualization injury in the en-dometrium,which lays a foundation for the research on m6A modifi-cation in decidualization.

Objective To explore the evaluation value of serum follistatin like protein 1(FSTL1)and glu-cose regulatory protein 78(GRP78)on disease severity and readmission in elderly patients with chronic ob-structive pulmonary disease(COPD).Methods A total of 100 elderly COPD patients(COPD group)treated in this hospital from March 2020 to May 2023 were selected as COPD group,and were divided into grade Ⅰ(35 cases),grade Ⅱ(46 cases)and grade Ⅲ(19 cases)according to the severity of the disease.Another 100 elderly volunteers who underwent physical examination during the same period were selected as the control group.Serum FSTL1 and GRP78 levels were detected by enzyme-linked immunosorbent assay(ELISA).Spearman and Pearson correlation were used to analyze the correlation between serum FSTL1 and GRP78 lev-els and general data.The evaluation value of serum FSTL1 and GRP78 levels in COPD patients on disease se-verity and readmission was analyzed by receiver operating characteristics(ROC)curve.Results Compared with the control group,serum levels of FSTL1 and GRP78 in COPD group were significantly increased(P＜0.05).Serum levels of FSTL1 and GRP78 in COPD patients increased with the severity of the disease(P＜0.05).Compared with non-readmission group,the serum levels of FSTL1 and GRP78 in readmission group were significantly increased(P＜0.05).Spearman correlation analysis showed that serum FSTL1 and GRP78 levels were positively correlated with smoking history,hypertension history and disease severity(P＜0.05).Pearson correlation analysis showed that serum FSTL1 and GRP78 levels were negatively correlated with arte-rial oxygen pressure(PaO2),the ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC),and the percentage of forced expiratory volume in the first second to expected value(FEV1％pred),with significance(P＜0.05),while it was positively correlated with the partial pressure of carbon diox-ide(PaCO2),with significance(P＜0.05).ROC curve analysis showed that serum FSTL1,GRP78 and their combined assessment of disease severity and readmitted area under the curve(AUC)were higher in COPD pa-tients,and the combination was significantly better than the single assessment(P＜0.05).Conclusion Serum levels of FSTL1 and GRP78 are significantly increased in COPD patients,which are correlated with the severi-ty of the disease and have a high value in evaluating the severity of the disease and readmission.

Objective To analyze the influencing factors of delirium after endovascular aortic repair, and to provide a basis for clinical nursing and prevention of this condition. Methods Patients who underwent endovascular aortic repair at Fuwai Hospital, Chinese Academy of Medical Sciences from 2018 to 2019 were selected. The Chinese version of the Nursing Delirium Screening Scale (Nu-DESC) was used to assess whether postoperative delirium occurred. Patients with a Nu-DESC score≥ 3 were assigned to the delirium group. Non-delirium patients who had the same surgeon and adjacent surgical order were selected at a 1 : 4 ratio to form the non-delirium group. Univariate analysis was performed on the clinical data of the two groups. Factors with P<0.1 in the univariate analysis and those considered clinically significant were included in a multivariate logistic regression analysis to identify the influencing factors of postoperative delirium. Stratified analysis was conducted based on thoracic endovascular aortic repair (TEVAR) and endovascular abdominal aortic repair (EVAR). Results A total of 213 patients were included, comprising 46 in the delirium group and 167 in the non-delirium group. The overall mean age was (60.3±12.0) years, and 183 (85.9%) were male. Univariate analysis showed that emergency admission, preoperative neutrophil percentage, aortic dissection, surgical duration, intubation time, and ICU stay may be associated with postoperative delirium. Multivariate analysis revealed that longer operative and intubation times were associated with a higher likelihood of delirium. In the stratified analysis, the results for the TEVAR group were consistent with the overall findings, whereas no significant differences were observed in the EVAR group. Conclusion Longer surgical and intubation times are associated with an increased risk of delirium in patients undergoing TEVAR. No significant factors influencing delirium are identified in patients undergoing EVAR.
