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.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Objective To investigate the application value of modified early warning score (MEWS) for assessment of patients in pre hospital first aid.Methods For patients with MEWS method in 3 478 cases of pre hospital first aid,scored in 0-4,5-9 and ≥ 10 points.Analysis of the relationship between the distribution and severity in patients with different grades,and tracing the fate and the condition of patients after admission.Results In MEWS patients with low 0-4 points was divided into pre hospital first aid,accounted for 69.18％ (2 406/3 478),severe cases accounted for 2.58％ (62/2 406); MEWS 5-9 accounted for 21.54％ (749/3 478),severe patients increased to 37.92％ (284/749); MEWS ≥ 10 points accounted for only 9.29％ (323/3 478),severe patients increased to 87.00％ (281/323).MEWS scores higher ratio in patients with severe more,MEWS 5-9 points,severe patients with MEWS ≥ 10 points 0-4 critical patients proportion (P ＜ 0.01).MEWS 5-9 points,≥ 10 points patients admitted to a specialist ward and intensive care units treatment compared with MEWS 0-4 points patients increased significandy (P ＜ 0.01),the mortality rate was also significandy increased (P ＜ 0.01).Conclusion The MEWS method in pre hospital first aid to early warning of potential in critically ill patients,the higher score,the more serious condition,the higher mortality rate.

Objective To observe the destructive and scavenging effect of ambroxol (AMB) on the biofilm (BF) of Pseudomonas aeruginosa (P.a).To evaluate the synergistically bactericidal effect of AMB along with levofloxacin (LFX) on BF of P.a.Methods The early model (cultured for 3 d) and mature model (cultured for 7 d) of P.a wild strain (PAO1) BF were established,in vitro,respectively.The models were randomly (random number) divided into control group,AMB group and AMB + LFX group.The concentrations of AMB were 256 μg/ml and 512 μg/ml,respectively.When the early BF model and mature BF model were made,different concentrations of AMB were added in AMB group and AMB + LFX (1μg/ml) was added in AMB + LFX group.The number of viable P.a on the BF carrier was counted with the continuous dilution method 24 h after AMB or/and LFX added.Then,the BF morphological changes on the carrier surface were observed by using scanning electron microscopy (SEM).Measured data were analyzed with single factor analysis of variance (One-Way ANOVA).Results Both in the early BF model and in the mature BF model,the SEM examination showed that the BF in AMB group was significantly reduced compared to the control group,and this reduction of BF was in dose-dependent manner.LFX 1 μg/ml could reduce the number of viable bacterial in BF in both early model and mature model (P ＜ 0.05).LFX with addition of different concentrations of AMB showed stronger bactericidal effect than LFX used alone identified by more significant reduction in the number of colonv within the BF (P ＜ 0.05).Furthermore,the LFX combined with 512 μg/ml AMB reduced more significant number of colony apparently than the LFX combined with 256 μg/ml AMB (P ＜ 0.05).Conclusions AMB can destroy the early BF or mature BF partly,and LFX alone can partly reduce the number of viable P.a within BF.When LFX combined with AMB,they exert a synergistically bactericidal effect.

Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common human hereditary disorder characteristic of development of bilateral multiple fluid-filled kidney cysts. Accumulated evidence has suggested that primary cilium of renal epithelial cell plays a key role in cystogenesis. In this article we will give an overview on the basic information about polycystic kidney disease (PKD) and summarize the recent progresses in studies of regulation of polycystin-1 and -2 trafficking to cilia. We will also discuss the possible role of trafficking defects of polycystins on the pathogenesis of ADPKD.

This study examined the effect of insulin on the expression of very low density lipoprotein receptor (VLDLR) subtypes of SGC7901 cells and discussed its biological implication. In vitro, moderately or poorly-differentiated human gastric adenocarcinoma cell line SGC7901 was incubated with insulin for different lengths of time, and then the expression of protein and RNA level in VLDLR subtypes were detected by Western blotting and real-time PCR, respectively. The results showed that, at certain time interval, insulin could down-regulate expression of type I VLDLR and up-regulate the expression of type II VLDLR in SGC7901 cells, at both protein and RNA level. We are led to conclude that insulin serves as a regulator in maintaining the balance between glucose and lipid metabolism in vivo, possibly through its effect on the differential expression of VLDLR subtypes.
