Objective To investigate the detection rate and related influencing factors of gastrointestinal diseases in grass-roots personnel.Methods A total of 481 grass-roots personnel were enrolled and examined by magnetic-controlled capsule endoscopy(MCCE).Multivariate logistic regression were used to analyze the influencing factors of gastrointestinal diseases detected by MCCE.Results All personnel completed MCCE,and gastrointestinal diseases were detected in 154(32.0%)cases,including 106 cases of erosive gastritis,25 cases of chronic atrophic gastritis,17 cases of digestive tract polyp,16 cases of gastric ulcer,5 cases of reflux esophagitis,4 cases of cardia,1 case of duodenitis,and 1 case of enteritis.Gastrointestinal diseases was correlated with special operation posts,long-term tasks within recent 6 months,abdominal distension,belching,nausea and vomiting,diarrhea and other symptoms(all P＜0.05).Multivariate logistic regression analysis showed that the risk factors of gastrointestinal diseases were working in special operation posts,performing long tasks within 6 months,belching,nausea and vomiting symptoms(all P＜0.05).Conclusion The overall detection rate of gastrointestinal diseases(mainly acid related diseases)is relatively high,and its incidence is closely related to working in special operation posts and performing long-term tasks within recent 6 months.Personnel working in special operation posts should be more alert to gastrointestinal diseases.Gastrointestinal symptoms have reference value for the prediction of lesions,but more attention should be paid to the identification of functional gastrointestinal diseases with endoscopy.

Objective To investigate the systemic immune-inflammation index(SII),albumin to globulin ratio(AGR),and high-sensitivity C-reactive protein(hs-CRP)in patients with ulcerative colitis(UC)compli-cated by Epstein-Barr virus(EBV)infection,and to evaluate their diagnostic value in UC complicated by EBV infection.Methods A total of 237 patients with UC admitted to the hospital from February 2024 to Septem-ber 2024.Patients were divided into a complicated group(150 cases)and a control group(87 cases)based on EBV-DNA test results.The counts of neutrophils,lymphocytes,and platelets,as well as the levels of albumin(ALB),globulin,hs-CRP,and erythrocyte sedimentation rate(ESR)were collected from the patients'routine blood tests,and the parameters of SII and AGR were calculated.Spearman correlation test was used for corre-lation analysis.Multivariate binary Logistic regression was used to analyze the influencing factors of EBV in-fection in UC patients,and receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of individual and combined detection of various indicators.Results There were statistically significant differences in disease activity,lesion range,ALB,AGR,ESR,hs-CRP,and SII between the complicated group and the control group(P<0.05).Correlation analysis showed that the positive copy number of EBV-DNA in the complicated group was positively correlated with disease activity,hs-CRP,and SII(P<0.05),and nega-tively correlated with ALB and AGR(P<0.05).Multivariate binary Logistic regression analysis indicated that SII and AGR were independent influencing factors for UC patients complicated by EBV infection.The combined detection of ALB,AGR,SII,hs CRP,ESR and various indicators has certain predictive value for UC patients with EBV infection.The area under the curve of the combined detection of ALB,AGR,SII,hs-CRP,ESR and the AUC of the combined detection of SII,AGR,hs-CRP were the largest,and the sensitivity and specificity were also high.Conclusion SII and AGR are independent influencing factors for UC patients com-plicated by EBV infection.The combined detection of SII,AGR,and hs-CRP has good diagnostic value for UC complicated by EBV infection and could serve as valuable biomarkers for evaluating UC complicated by EBV infection.

Objective:To explore the effectiveness and safety of different anticoagulation strategies during continuous blood purification (CBP) treatment,providing a reference for anticoagulation strategies in critically ill children undergoing CBP.Methods:A retrospective study was conducted,including children admitted to the PICU of Children's Hospital of Fudan University from January 2019 to December 2024.According to the anticoagulation methods used during CBP treatment,patients were divided into the sodium citrate group and the heparin group.CBP was performed using continuous venovenous hemofiltration or continuous venovenous hemodialysis filtration mode,with a blood flow rate of 3-5 mL/(kg·min),replacement fluid rate of 30-50 mL/(kg·h),and dialysis fluid rate of 20-30 mL/(kg·h).The filter lifespan,28-day all-cause mortality,total length of hospital stay,PICU stay duration,adverse events,and associated costs were compared between the two groups.Results:A total of 221 children were included (105 in the sodium citrate group and 116 in the heparin group),with a cumulative use of 666 filters (284 in the sodium citrate group and 382 in the heparin group).(1) There were no statistically significant differences in general data,including age,sex ratio,underlying diseases,the ratio and duration of invasive mechanical ventilation,vasopressor scores at baseline,and indications for CBP between the two groups (all P>0.05).(2) The filter lifespan was 20(14,32) hours for the sodium citrate group and 21(13,35) hours for the heparin group,with no statistically significant difference between the two groups ( P>0.05); the proportion of accidental downstroke was 2.8% and 6.5%,respectively,with a statistically significant difference ( P=0.029); among the 221 children,86 died,with 38 deaths (35.2%) in the sodium citrate group and 49 deaths (38.9%) in the heparin group,showing no statistically significant difference.(3) The sodium citrate group had a higher incidence of metabolic alkalosis,hypocalcemia,and sodium citrate accumulation (44.4% vs. 1.6%,32.7% vs 9.4%,7.7% vs 0,all P<0.01); the heparin group had a greater proportion of bleeding (6.0% vs. 2.9%) and was more likely to develop heparin-induced thrombocytopenia (10.2% vs. 0, P<0.01).(4) The total hospitalization costs for the sodium citrate group were significantly higher than for the heparin group (200 327 yuan vs. 152 077 yuan, P=0.05); costs related to the use of anticoagulants and monitoring indicators during CBP treatment were also higher in the sodium citrate group (2 479 yuan vs. 682 yuan, P<0.01). Conclusions:Sodium citrate is a safe and effective anticoagulation method for critically ill children undergoing CBP,which can reduce the risk of filter clotting compared to systemic heparin anticoagulation.

To evaluate the clinical application value of magnetic bead sorting technology (MBS) using the T-cell select kit combined with an automatic cell sorter for isolating peripheral blood mononuclear cells (PBMCs) to realize automated specimen pre-processing and process optimization in T-SPOT.TB assay. A cross-sectional study was conducted involving 300 patients recruited from the first affiliated hospital of Air Force Medical University from March 2023 to July 2024. Among them, there were 167 males and 133 females. The age range of the patients was 18 to 65 years, with a median age of 49.0 (33.3, 59.0) years and a mean age of (46.4±13.9) years. 4 ml of anticoagulated whole blood samples in duplicate were collected from each patient. One fresh sample (0-4 h) was processed immediately using density gradient centrifugation (DGC) for PBMC isolation, while the other was processed using MBS method at either 0-4 h or 34-54 h post-collection. The cycles for cell enrichment step of the automatic cell sorter were adjusted from the conventional 4 cycles to 2 cycles. Statistical analysis was performed using Cohen′s Kappa test to evaluate the concordance of T-SPOT.TB results across all processing groups. The results showed that for fresh samples (0-4 h), the T-SPOT.TB results for samples processed with 4-cycle and 2-cycle MBS enrichment steps demonstrated positive concordance rates of 91.7% and 93.1%, negative concordance rates of 100% for both, overall concordance rates of 98.0% and 97.9%, and Kappa values of 0.94 and 0.95, respectively, compared with the reference results for paired samples processed using DGC. Correspondingly, the results for samples processed with the 4-cycle and 2-cycle MBS methods at 34-54 h post-collection yielded positive concordance rates of 90.0% and 81.3%, negative concordance rates of 95.1% and 100%, overall concordance rates of 93.0% and 82.9%, and Kappa values of 0.86 and 0.43, respectively, compared with the reference results for fresh samples processed using DGC. In conclusion,for 0-4 h samples, the T-SPOT.TB results from both 4-cycle and 2-cycle MBS enrichment protocols were highly consistent with the reference results from conventional DGC methods. However, for 34-54 h stored samples, results from the 4-cycle MBS method rather than the 2-cycle protocol exhibited significantly superior concordance with the reference results. The MBS method using T-Cell Select kit achieves automated sample pre-processing for T-SPOT.TB assay, reduces hands-on time, and provides a viable alternative with reliable results for long-stored specimens.
