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 compare the efficacy and prognostic impact of ruiyun procedure for hemorrhoid(RPH)and procedure for prolapse and hemorrhoid(PPH)in patients with mixed hemor-rhoids.Methods A total of 218 patients with mixed hemorrhoids who underwent surgical treatment in the Gastrointestinal Surgery Department of our hospital from November 2022 to October 2023 were included in this study.According to differed surgical methods,the patients were divided into RPH group(n=108)and PPH group(n=110).The operative time,intraoperative blood loss,length of hospital stay,surgical treatment outcomes,postoperative complication rates,and recurrence rates were compared between the two groups.The Visual Analogue Scale(VAS)was used to assess pain degree of patients before surgery,24 hours after surgery,and during the first defecation.The 36-Item Short Form Health Survey(SF-36)was employed to evaluate the quality of life,and the Patient Satis-faction Questionnaire(PSQ)was used to investigate patients' satisfaction with the surgical treatment.Results The total effective rate of treatment in the RPH group was 88.89％,which was higher than 78.18％in the PPH group(P＜0.05).The operative time,intraoperative blood loss,and length of hospital stay in the RPH group were shorter or less than those in the PPH group(P＜0.05).The VAS scores at 24 hours after surgery and during the first defecation in the RPH group were lower than those in the PPH group,and the differences were statistically significant(P＜0.05).After surgery,the SF-36 and PSQ scores in both the RPH and PPH groups were higher than those before surgery,and the scores in the RPH group were higher than those in the PPH group,with statistically signifi-cant differences(P＜0.05).The incidence of postoperative complications in the RPH group was lower than that in the PPH group,and the difference was statistically significant(P＜0.05).Six months after surgery,there was no significant difference in the recurrence rates between the two groups(P＞0.05).Conclusion Both RPH and PPH are effective surgical methods for the treat-ment of mixed hemorrhoids.RPH is superior to PPH in reducing postoperative complications and shortening the length of hospital stay,but there is no significant difference in the postoperative recur-rence rates between the two methods.

A simple and rapid immunochromatographic test strip incorporating a colloidal gold-labeled recombinant Nsp7 antigen probe was successfully developed for the detection of anti-porcine reproductive and respiratory syndrome virus (PRRSV) antibodies in swine. Recombinant Nsp7 protein of PRRSV labeled with colloidal gold was dispensed on a conjugate pad for use as the detector. Staphylococcal protein A and purified porcine anti-Nsp7 antibodies were blotted on a nitrocellulose membrane to form test and control lines, respectively. A comparison of the strip with standard diagnostic tests, enzyme-linked immunosorbent assays and immunoperoxidase monolayer assay, was also performed. The immunochromatographic test strip was shown to be of high specificity and sensitivity. Furthermore, the strip assay is rapid and easy to perform with no requirement for professional-level skills or equipment. It is suggested that the immunochromatographic test strip can be used to quickly and accurately detect PRRSV antibody and to be suitable for diagnostic purposes in the field.
