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 explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.

The aim of this study is to establish a simple and accurate method for vaccine immune e-valuation of porcine pseudorabies virus.In this research,PRV-gD recombinant protein was ex-pressed from mammalian cell HEK-293F as coating antigen,and then the reaction conditions of gD-iELISA were optimized according to checkerboard titration method.The gD-iELISA was used to detect the antibody levels of 211 clinical pig serum samples and the consistency with the neu-tralizing antibody levels wasanalyzed.The results showed that the antigen coating concentration was 0.90 mg/L;the serum to be detected was diluted 1∶100 and incubated at 37 ℃ for 30 min;goat anti-pig IgG-HRP antibody was diluted 1∶55 000 and incubated at 37 ℃ for 30 min;TMB sub-strate was developed at 37 ℃ for 20 min.The method could detect 1∶6 400 diluted PRV positive serum.The results of CSFV,PRRSV,PCV-2,PEDV and FMDV positive sera were all negative by gD-iELISA,and there was no cross-reaction between the method and the above positive sera.The coincidence rate of gD-iELISA and commercial kits was 95.26％,and the intra-and inter-batch co-efficients of variation were both less than 10％.Correlation analysis showed that the correlation coefficient(r)between gD antibody level and neutralizing antibody level was significantly greater than that of gB antibody level,and the gD antibody level had a good linear relationship with the neutralizing antibody level.The results indicated that gD-iELISA was more suitable for vaccine im-mune evaluation of PRV than gB-iELISA.Therefore,the method will have a good prospect of ap-plication in the immunization control of the PRV.

OBJECTIVE: To evaluate the regulatory effect of berberine on autophagy and apoptosis balance of fibroblast-like synoviocytes (FLSs) from patients with in rheumatoid arthritis (RA) and explore the mechanism. METHODS: The inhibitory effect of 10, 20, 30, 40, 50, 60, 70, and 80 μmol/L berberine on RA-FLS proliferation was assessed using CCK-8 method. Annexin V/PI and JC-1 immunofluorescence staining was used to analyze the effect of berberine (30 μmol/L) on apoptosis of 25 ng/mL TNF-α- induced RA-FLSs, and Western blotting was performed to detect the changes in the expression levels of autophagy- and apoptosis-related proteins. The cells were further treated with the autophagy inducer RAPA and the autophagy inhibitor chloroquine to observe the changes in autophagic flow by laser confocal detection of mCherry-EGFP-LC3B. RA-FLSs were treated with the reactive oxygen species (ROS) mimic H₂O₂ or the ROS inhibitor NAC, and the effects of berberine on ROS, mTOR and p-mTOR levels were observed. RESULTS: The results of CCK-8 assay showed that berberine significantly inhibited the proliferation of RA-FLSs in a time- and concentration-dependent manner. Flow cytometry and JC-1 staining showed that berberine (30 μmol/L) significantly increased apoptosis rate (P < 0.01) and reduced the mitochondrial membrane potential of RA-FLSs (P < 0.05). Berberine treatment obviously decreased the ratios of Bcl-2/Bax (P < 0.05) and LC3B-II/I (P < 0.01) and increased the expression of p62 protein in the cells (P < 0.05). Detection of mCherry-EGFP-LC3B autophagy flow revealed obvious autophagy flow block in berberine-treated RA-FLSs. Berberine significantly reduced the level of ROS in TNF-α-induced RA-FLSs and upregulated the expression level of autophagy-related protein p-mTOR (P < 0.01); this effect was regulated by ROS level, and the combined use of RAPA significantly reduced the pro-apoptotic effect of berberine in RA-FLSs (P < 0.01). CONCLUSION Berberine can inhibit autophagy and promote apoptosis of RA-FLSs by regulating the ROS-mTOR pathway.

Objective:To evaluate the effect of two-way referral service in referral and treatment of patients with coronary disease.Methods:A non-randomized controlled study was used, 80 patients with coronary disease who were referred to the First Affiliated Hospital of Xinjiang Medical University through the fast referral channel, also called green referral channel (GRC) of telemedicine service mode from January 2021 to January 2022 were selected as the GRC referral group. A propensity score was used to match 110 patients from the same period with coronary disease who were referred to this hospital through conventional medical channels and had similar basic conditions such as age, gender, region and medical insurance type as the conventional referral group. The differences in disease severity, referral time, hospitalization cost and other indicators were compared using t-test, χ2 test and nonparametric test between the two groups, and the satisfaction of the GRC referral group was investigated. Results:The proportion of patients with heart function grade Ⅲ (NYHA grading), heart failure, atrial fibrillation and interventional therapy in the GRC referral group was significantly higher than conventional referral group (all P<0.05). The total referral time and bed waiting time of patients in the GRC referral group were significantly shorter than conventional referral group [14.16 (9.62, 25.61) vs 34.39 (28.51, 49.68) h, 2.13 (0.83, 6.64) vs 24.58 (20.27, 27.68) h] ( Z=8.465, 9.172, all P<0.001). The hospitalization cost, surgical treatment cost and material cost in GRC referral group were significantly higher than conventional referral group [24 755 (11 559, 56 521) vs 14 700 (9 375, 29 534) CNY, 6 013 (2 096, 8 256) vs 2 562 (2 044, 6 154) CNY, 12 093 (1 267, 35 689) vs 1 329 (826, 16 125) CNY] ( Z=2.814, 2.917, 3.353, all P<0.05), and the diagnosis cost was significantly lower than conventional referral group [4 878 (3 628, 6 847) vs 5 719 (4 228, 7 639) CNY] ( Z=2.323, P<0.05). In the GRC referral group, the satisfaction rates with referral process, visit time and patient experience were all above 90%. Conclusion:Two-way referral service based on telemedicine has a good application effect in the referral and treatment of patients with coronary disease.

Objective:To investigate the correlation between cognitive function and living ability of older adult patients living in a mining community.Methods:A total of 180 older adult patients living in a mining community who received treatment during July-October 2019 were included in this study. They were randomly divided into the low-age group (< 68 years old, n = 94) and the high-age group (≥ 68 years old, n = 86). Cognitive function and living ability were evaluated using the Mini-Mental State Examination (MMSE), The Montreal Cognitive Assessment (MoCA), and the Activity of Daily Living Scale (ADL). The relationship between cognitive function and living ability was investigated using hierarchical analysis and Pearson correlation analysis. Results:The proportions of older adult patients with abnormal cognitive function identified by the MMSE and MoCA were 39.4% and 66.0%, respectively in the low-age group, and they were 32.6% and 61.6%, respectively in the high-age group. The MoCA had a greater performance in identifying abnormal cognitive function in each group than the MMSE ( χ2 = 26.69, 10.18, both P < 0.001). There were no significant differences in proportions of older adult patients with abnormal cognitive function identified by the MMSE and MoCA between low-age and high-age groups ( χ2 = 0.90, 0.36, both P > 0.05). The proportion of older adult patients with abnormal living ability was not significantly different between low-age and high-age groups (4.3% vs. 10.5%, χ2 = 2.58, P > 0.05). Compared with patients negative for MMSE items, living ability and instrumental activity of daily living increased by 7.0% and 9.4% in low-age patients positive for MMSE items (both P < 0.05). Compared with patients negative for MoCA items, living ability increased by 3.5% in low-age patients positive for MoCA items ( P < 0.05). Correlation analysis revealed that total scores of MMSE and MoCA were significantly negatively correlated with ADL score ( r = -0.26, -0.27, both P < 0.001) and instrumental activity of daily living score ( r = -0.27, -0.27, P < 0.001). Conclusion:Cognitive function and living ability are correlated in older adult patients living in a mining community. We should pay attention to the screening results of cognitive disorder in older adult patients and improve their living ability by improving their cognitive function.
