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 effects of three different patient-controlled analgesia protocols on sedation and analgesia in patients undergoing thoracoscopic surgery for lung cancer.Methods Ninety-three patients undergoing thoracoscopic surgery for lung cancer in our hospital from November 2022 to April 2023 were selected,and randomly assigned into three groups according to different postoperative analgesic protocols.Group P(n=30)was given patient-controlled intravenous analgesia,group T(n=31)received patient-controlled intravenous analgesia combined with thoracic paravertebral block,while group S(n=32)received patient-controlled intravenous analgesia combined with serratus intercostal plane block.Then the Visual Analogue Scale(VAS)score,Ramsay sedation scores,the press times of analgesic pump,the use of sedative drugs and adverse effects were compared among all three groups,and the sensory block plane,performance time,onset time and duration of the block were compared between group T and S.Results VAS scores in the resting state at postoperative 2 h,24 h and 48 h were(3.09±0.69),(2.83±0.59)and(2.07±0.51)in group P,which were higher than group T[(1.22±0.33),(2.51±0.54)and(1.57±0.45)]and group S[(1.01±0.30),(2.23±0.51)and(1.22±0.25)],group T was higher than group S.VAS scores in the coughing state at postoperative 2 h,24 h and 48 h were(3.63±0.55),(3.24±0.67)and(2.61±0.51)in group P,which were higher than the group T[(1.45±0.29),(2.71±0.56)and(2.33±0.53)]and group S[(1.14±0.28),(2.40±0.57)and(2.03±0.52)],group T was higher than group S.VAS scores in the resting and coughing states at postoperative 2 h,24 h and 48 h yielded statistical difference among three groups(all P＜0.05).Ramsay sedation scores at postoperative 2 h,24 h and 48 h were(2.21±0.51),(2.34±0.56)and(2.31±0.55)in group P,(2.23±0.53),(2.35±0.55)and(2.33±0.54)in group T and(2.22±0.52),(2.36±0.57)and(2.32±0.55)in group S,with no statistical difference(all P＞0.05).The press times of analgesic pump at postoperative 24 h and 48 h were(10.18±2.42)and(14.51±3.20)in group P,which were higher than the group T[(3.32±0.79)and(6.84±1.62)]and group S[(1.17±0.28)and(2.63±0.62)],group T was higher than group S,with statistical difference(all P＜0.05).The additional dose of sufentanil and the total amount of sufentanil used in postoperative period were(8.05±1.99)μg and(71.53±6.91)μg in group P,which were more than the group T[(3.77±0.93)pg and(65.82±5.77)μg]and the group S[(2.23±0.55)μg and(47.54±4.56)μg],group T was higher than group S,with statistical difference(all P＜0.05).Group S had shorter performance time[(5.32±1.77)min]and longer block duration time[(12.51±2.14)h]than those of group T[(12.41±3.42)min and(10.31±2.01)h],with statistical difference(all P＜0.05).The incidence of adverse reactions was 6.25％in group S,which was lower than the group P(30.00％,P＜0.05),and no statistical difference was reported among three groups in the occurrence rate of comparisons(all P＞0.05).Conclusion The sedation effects of the three different patient-controlled analgesia protocols are comparable,but patient-controlled intravenous analgesia combined with serratus intercostal plane block provides better postoperative analgesia for patients undergoing thoracoscopic surgery for lung cancer,which has less analgesic pump presses and lower dose of postoperative analgesic drugs used,and fewer adverse effects.

As a common respiratory disease in children, asthma affects children′s physical and mental health and increases the burden on families and society.Patients with asthma can have one or more comorbidities, and these asthma comorbidities not only make the diagnosis of asthma more difficult, but also affect the control and treatment and outcome of the disease.However, asthma comorbidities are often under-recognized and poorly-managed.Therefore, it is important to improve the understanding of asthma comorbidities and to correctly identify, diagnose and treat them.Asthma in children contains a variety of comorbidities.This article reviews the research progress of epidemiology, impact on asthma and the treatment of these common comorbidities of asthma in children.

To study the lead excretion effect of the chelator Zn-DTPA on the lead intoxication mice, inductively coupled plasma mass spectrometry (ICP-MS) was applied to detect the lead content of biological samples. The acute lead intoxication mice model was established by injecting lead acetate intraperitoneally with the dose of 1 mg. Zn-DTPA was administered intraperitoneally to mice once daily for five consecutive days 4 h after intoxication. Control group, model group, combination of Zn-DTPA and Ca-DTPA group were evaluated at the same time. The urine was collected every day. The mice were sacrificed in batches in the 2rd, 4th, 6th day. Biological samples including urine, whole blood, femur and brain were prepared and nitrated. Lead concentration was detected by ICP-MS. The result showed that Zn-DTPA could increase lead content in urine markedly and reduce lead content in blood, femur and brain.
