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.

In pursuit of effective agents for hepatocellular carcinoma derived from the Artemisia species, this study built upon initial findings that an ethanol (EtOH) extract and ethyl acetate (EtOAc) fraction of the aerial parts of Artemisia dubia Wall. ex Bess. exhibited cytotoxicity against HepG2 cells with inhibitory rates of 57.1% and 84.2% (100 μg·mL^-1), respectively. Guided by bioactivity, fourteen previously unidentified sesquiterpenes, artemdubinoids A-N (1-14), were isolated from the EtOAc fraction. Their structural elucidation was achieved through comprehensive spectroscopic analyses and corroborated by the comparison between the experimental and calculated ECD spectra. Single crystal X-ray diffraction provided definitive structure confirmation for artemdubinoids A, D, F, and H. Artemdubinoids A and B (1-2) represented unique sesquiterpenes featuring a 6/5-fused bicyclic carbon scaffold, and their putative biosynthetic pathways were discussed; artemdubinoid C (3) was a novel guaianolide derivative that might be formed by the [4 + 2] Diels-Alder reaction; artemdubinoids D and E (4-5) were rare 1,10-seco-guaianolides; artemdubinoids F-K (6-11) were chlorine-containing guaianolides. Eleven compounds exhibited cytotoxicity against three human hepatoma cell lines (HepG2, Huh7, and SK-Hep-1) with half-maximal inhibitory concentration (IC₅₀) values spanning 7.5-82.5 μmol·L^-1. Artemdubinoid M (13) exhibited the most active cytotoxicity with IC₅₀ values of 14.5, 7.5 and 8.9 μmol·L^-1 against the HepG2, Huh7, and SK-Hep-1 cell lines, respectively, which were equivalent to the positive control, sorafenib.

Objective To establish a nursing shared governance model and compare the difference of structural empowerment level between participants and non-participants. Methods Convenient sampling method was used and a total of 583 clinical nurses were investigated by structural empowerment questionnaire. Results Independent sample t test showed no difference in gender, age, and working years between observation group(228) and control group(355) (P>0.01); Pre-test showed no difference between two groups, after one year application, structural empowerment level showed significant difference between observation group (3.73 ± 0.66) and control group(3.10 ± 0.56) (t=3.624,P<0.01). Structural empowerment level increased in both groups(t=-3.482,-14.346, P<0.01). Conclusions Shared governance model is effective in evaluating nurses′structural empowerment level.

Objective To observe the change of the protein and gene expression of hypoxia inducing factor-1α(HIF-1a) and vascular endothelial growth factor (VEGF) in the nude mouse tumor,which has been treated by HIFU combined with nanoscale ultrasound molecular probes with HSV1-TK gene microvascular density.Methods Sixty nude mice were implanted with HepG2 Cells to establish subcutaneous transplanted tumor.Divided this mice into six groups at random after treated by HIFU:MB+ HSV-TK+ GPC3 (group A),MB + HSV-TK (group B),HSV-TK +GPC3 (group C),HSV-TK (group D),MB + GPC3 (group E),PBS (group F).They were injected into the tail vein every after 3 days.Mice in group A,B,D and E were exposed to ultrasound by 2 W/cm2,1 MHz,5 mintues and 0.2 mL ganciclovi(GCV) was intraperitoneally injected at the first 48 hours after injection.After the treatment,immunohistoche were used to detect the microvascular density(MVD),Western blot and immunohistoche was employed to test the protein change of the VEGF and HIF-1α,Q-PCR was used to test the mRNA gene transcription of VEGF and HIF-1α in the tumor tissues.Results After 14 days,the protein expression of HIF-1α and VEGF in group A was significantly lower than that in group B,C,D,E and F (P＜0.05),the MVD level in the tumor is also like this,and the difference is statistically significant.Conclusion Anoscale ultrasound molecular probes with HSV1-TK can reduce the the level of VEGF,MVD and HIF-1α in the tumor which has been treated by HIFU,so it can inhibit tumor growth and improve the therapeutic efficacy after HIFU treatment.

OBJECTIVETo investigate the genetic association between cirrhosis and polymorphisms in the genes encoding major histocompatibility complex, class II (HLA)-DR beta 1 (DRB1) and HLA-DP beta 1 (DPB1).

METHODSA population of 168 parent/offspring trios, in which the proband had a diagnosis of hepatitis B virus infection with clinical signs of cirrhosis.The HLA-DRB1 and DPB 1 gene polymorphisms of rs24755213 and rs202176660 were detected by PCR and single nucleotide polymorphism (SNP) genotyping.Correlation analysis and haplotype relative risk analysis were carried out.

RESULTSA/G genotypes were detected in rs24755213 of HLA-DRB1 and C/T genotypes were detected in rs202176660 of DPB1.The rs24755213 allele was associated with cirrhosis (P=0.014), with the G allele identified as a protective factor (Z=-2.33) and the A allele identified as a hazard factor (Z=2.33).The rs202176660 allele was also associated with cirrhosis (P =0.026), with the T allele identified as a protective factor (Z=-2.06) and the C allele identified as a hazard factor (Z=2.06).The haplotypes of G/T and A/C in rs24755213 and rs202176660 respectively were associated with cirrhosis (P =0.037 and 0.002, Z=-2.12 and 2.09 respectively).

CONCLUSIONIn this group of Chinese patients with hepatitis B virus-related cirrhosis, polymorphisms in the HLA-DRB 1 and DPB1 genes were associated with cimhosis.

Objective:To evaluate and screen the anti-atrial ifbrillation drug with multiion channel targets by micro-electrode chip technology in a rapid atrial pacing (RAP) rabbit model.
Methods:A total of 32 rabbits were randomly divided into 4 groups, n=8 in each group. Potassium channel blocker (TEA) group, Potassium channel blocker (BaCl2) group, Potassium channel blocker (CdCl2) group and Amiodarone group.
The electrode was inserted into right atrium via internal jugular vein with rapid right atrial pacing (600 beat/min) and the effect of each anti-atrial ifbrillation drug on ifeld action potential (fAPD) were measured in different groups.
Results:With 24 hour RAP, the fAPD was prolonged from (176.67 ± 8.66) ms to (196.11 ± 10.76) ms, P=0.012 in TEA group;from (182.22 ± 12.87) ms to (191.11 ± 13.09) ms, P=0.039 in BaCl2 group;from (178.33±7.85) ms to (206.67 ± 9.70) ms, P=0.0015 in CdCl2 group;from (167.38 ± 13.67) ms to (185 ± 15.14) ms, P=0.002 in Amiodarone group.
Conclusion: RAP induced atrial fibrillation in experimental rabbit model is a simple and feasible method for screening the anti-atrial fibrillation drugs, combining with micro-electrode chip technology, it might be used for developing the new product.
