Background::Patients who undergo coronary artery bypass grafting (CABG) are known to be at a significant risk of experiencing long-term adverse events, emphasizing the importance of regular assessments. Evaluating health-related quality of life (HRQoL) serves as a direct method to gauge prognosis. Our objective is to ascertain the prognostic significance of consecutive HRQoL assessments using the Physical Component Summary (PCS) and Mental Component Summary (MCS) derived from the Short-Form 36 (SF-36) health survey in CABG patients.Methods::The study population consisted of 433 patients who underwent isolated elective CABG at Fuwai Hospital between 2012 and 2013. SF-36 assessments were conducted during both the hospitalization period and follow-up. The primary endpoint of the study was all-cause mortality, while the secondary outcome was a composite measure including death, myocardial infarction, stroke, and repeat revascularization. We assessed the relationships between the PCS and MCS at baseline, as well as their changes during the first 6 months after the surgery (referred to as ΔPCS and ΔMCS, respectively), and the observed outcomes.Results::The patients were followed for an average of 6.28 years, during which 35 individuals (35/433, 8.1%) died. After adjusting for clinical variables, it was observed that baseline MCS scores (hazard ratio [HR] for a 1-standard deviation [SD] decrease, 1.57; 95% confidence interval [CI], 1.07–2.30) and ΔMCS (HR for a 1-SD decrease, 1.67; 95% CI, 1.09–2.56) were associated with all-cause mortality. However, baseline PCS scores and ΔPCS did not exhibit a significant relationship with all-cause mortality. Notably, there was a dose-response relationship observed between ΔMCS and the likelihood of all-cause mortality (HRs for the 2nd, 3rd and 4th quartiles compared to the 1st quartile, 0.33, 0.45 and 0.11, respectively).Conclusions::Baseline MCS and changes in MCS were independent predictors for long-term mortality of CABG. Better mental health status and recovery indicated better prognosis.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Background::The potential impact of pre-existing coronary artery stenosis (CAS) on acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and the elevation of high-sensitivity cardiac troponin I (hs-cTnI) levels in patients with PE.Methods::In this multicenter, prospective case-control study, 88 cases and 163 controls matched for age, sex, and study center were enrolled. Cases were patients with PE with elevated hs-cTnI. Controls were patients with PE with normal hs-cTnI. Coronary artery assessment utilized coronary computed tomographic angiography or invasive coronary angiography. CAS was defined as ≥50% stenosis of the lumen diameter in any coronary vessel >2.0 mm in diameter. Conditional logistic regression was used to evaluate the association between CAS and hs-cTnI elevation.Results::The percentage of CAS was higher in the case group compared to the control group (44.3% [39/88] vs. 30.1% [49/163]; P = 0.024). In multivariable conditional logistic regression model 1, CAS (adjusted odds ratio [OR], 2.680; 95% confidence interval [CI], 1.243–5.779), heart rate >75 beats/min (OR, 2.306; 95% CI, 1.056–5.036) and N-terminal pro-B type natriuretic peptide (NT-proBNP) >420 pg/mL (OR, 12.169; 95% CI, 4.792–30.900) were independently associated with elevated hs-cTnI. In model 2, right CAS (OR, 3.615; 95% CI, 1.467–8.909) and NT-proBNP >420 pg/mL (OR, 13.890; 95% CI, 5.288–36.484) were independently associated with elevated hs-cTnI. Conclusions::CAS was independently associated with myocardial injury in patients with PE. Vigilance towards CAS is warranted in patients with PE with elevated cardiac troponin levels.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the effects of cultured mycelium Cordyceps sinensis(CMCS)on the AMPK/SirT1 signaling pathway in carbon tetrachloride(CCl4)-induced liver fibrosis in mice.Methods Forty male SPF-grade C57BL/6 mice were divided randomly into a normal control group,CMCS control group(3.0 g/kg),model control group,CMCS1.5 g/kg group,and CMCS 3.0 g/kg group.Mice were injected intraperitoneally with 10%CCl4(2 mL/kg)to induce liver fibrosis.Two weeks later,serum levels of alanine transaminase(ALT),aspartate transaminase(AST),and total bilirubin(TBil)were measured.Inflammation and collagen deposition in liver tissue were observed by hematoxylin and eosin(HE)and Sirius red staining,respectively.The content of hydroxyproline in liver tissue was detected by Jamall's hydrochloric acid hydrolysis method.Levels of interleukin(IL)-6,monocyte chemoattractant protein-1(MCP-1),interferon,tumor necrosis factor(TNF),IL-10,and IL-12p70 in liver tissue were detected using a cytometric bead array analysis system.Collagen Ⅰ and SirT1 expression in liver tissue were detected by immunohisotochemistry,and Prkaa1,Prkaa2,Lkb1,and p53 gene expression were detected by real-time fluorescent quantitative reverse transcriptase-polymerase chain reaction.Results Serum levels of ALT,AST,and TBil were significantly increased in the model control group compared with those in the normal control group(P＜0.05).HE and Sirius red staining showed extensive inflammatory cell infiltration and collagen deposition in the liver,respectively.Hydroxyproline content and expression levels of IL-6,MCP-1,and TNF in the liver were significantly increased(P＜0.05),while IL-10 and IL-12p70 levels were significantly decreased(P＜0.01).Immunohistochemical staining revealed an increase in Collagen Ⅰ expression and SirT1 staining was decreased in the hepatic sinusoidal space,while collagen deposition was increased.Prkaa1,Prkaa2,and Lkb1 gene expression levels were decreased and p53 was increased in liver tissue(P＜0.05).CMCS significantly reduced serum ALT and AST levels,decreased IL-6,MCP-1,and TNF expression in liver tissue(P＜0.05),up-regulated IL-10 and IL-12p70(P＜0.05),alleviated liver inflammation,collagen deposition,and hydroxyproline content,up-regulated the expression of SirT1 in the hepatic sinusoidal space,enhanced Prkaa1,Prkaa2,and Lkb1 expression(P＜0.05),and down-regulated Collagen Ⅰ and p53(P＜0.05)in the liver.Compared with CMCS 1.5 g/kg,CMCS 3.0 g/kg significantly inhibited liver inflammation and collagen deposition and up-regulated AMPK/SirT1 expression(P＜0.05).Conclusions CMCS could improve CCl4-induced liver fibrosis via up-regulation of the AMPK/SirT1 signaling pathway.

Objective To analyze the predictive value of serum solitary G protein-coupled receptor ligand-12(Apelin-12)combined with echocardiographic parameters,wall motion score(WMS)and left ventricular global longitudinal strain(LV-GLS)for heart failure(HF)in elderly patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods A total of 98 elderly AMI patients undergoing PCI in our hospital from January 2021 to December 2023 were enrolled,and according to the occurrence of HF or not at 3 months after PCI,they were divided into HF group(39 cases)and non-HF group(59 cases).PCI procedure was completed within 12 h after admission,and the blood samples were collected and echocardiography was per-formed at discharge.ROC curve was plotted to evaluate the predictive value of Apelin-12,WMS and LV-GLS for HF in elderly AMI patients.Kappa consistency test was conducted to assess the accuracy of combined the three indicators in predicting HF in the patients.Results The HF group had significantly lower serum Apelin-12 level,and higher WMS and LV-GLS than the non-HF group(P＜0.01).ROC curve analysis showed that the AUC value of Apelin-12,WMS and LV-GLS in predicting HF after PCI in elderly AMI patients was 0.931,0.745 and 0.749,respec-tively,and their cut-off values was 1.55 μg/L,20.50 and-12.90％,respectively.Multivariate lo-gistic regression analysis revealed that serum Apelin-12＜1.55 μ g/L,WMS＞20.50 points,and LV-GLS＞-12.90％were independent risk factors for postoperative HF in elderly AMI patients(OR=3.508,95％CI:2.002-6.147);OR=2.818,95％CI:1.479-5.371;OR=2.841,95％CI:1.505-5.363).When the three indicators combined in tandem,that is,when serum Apelin-12＜1.55 μg/L,WMS＞20.50 and LV-GLS＞-12.90％,HF was predicted to be positive,with a speci-ficity increasing to 94.92％and a Kappa value of 0.714(P＜0.01).Conclusion Detection of serum Apelin-12,WMS and LV-GLS is beneficial for elderly AMI patients after PCI in predicting the oc-currence of HF,and can open up a new direction for clinical diagnosis and treatment.

Objective:To explore the association between changes in brain structural network during the early stage of stroke recovery and the onset of post-stroke depression (PSD).Methods:A total of 87 acute ischemic stroke patients scheduled for discharge, who were admitted to the Yixing Hospital Affiliated to Jiangsu University from March 2020 to May 2021, were prospectively collected. During the same period, 34 healthy control subjects matched with the stroke patients were also collected. All participants underwent systematic magnetic resonance imaging scans and scale assessments, and were followed up longitudinally for 2 years. Based on the occurrence of depression during follow-up, the stroke patients were divided into PSD group and post-stroke non-depression (PSND) group. Graph theoretical analysis was used to analyze the topological characteristics of brain structural network. Analysis of variance was used to explore the differences in brain structural network attributes among groups. Logistic regression model was used to analyze the predictive power of differential brain network attributes for PSD. Linear regression analysis was conducted to investigate the relationship between the synergism of non-rich-club regions and changes in rich-club connectivity.Results:The rich-club connectivity and synergism of the non-rich-club regions were significantly lower in the PSD group than in the PSND group (rich-club connectivity, P<0.01; synergism of feeder/local, P<0.001). The regression model demonstrated that the synergism of non-rich-club regions had a good predictive power for the occurrence of PSD ( OR=1.195, 95%CI 1.073-1.471, P<0.001). Furthermore, linear regression analysis revealed a significant correlation between the synergism of non-rich-club regions and Δrich-club connectivity ( r=-0.691, P<0.001). Conclusion:The good synergism of non-rich-club regions during the early stage of stroke recovery promotes the repair of rich-club connectivity and inhibits the onset of PSD.

Curettage is the main treatment method for oral maxillofacial cystic lesions,but simple curettage may easily damage surrounding structures such as adjacent teeth and nerves,leading to incomplete removal of the cyst and large jaw defects.The curettage assisted by endoscopy can provide a good surgical field for the surgeons,can clearly identify the important anatomical structure during the operation and can remove the cyst wall tissue as much as possible,thereby reducing the damage and reducing the recurrence rate of the lesion.This article combines the characteristics of maxillofacial surgery with clinical treatment experience,summarizes relevant literature from both domestic and international sources,and engages in discussions with experts in order to provide reference for the clinical treatment of jaw cystic lesions with endo-scope assisted curettage.

Objective To explore risk factors of early lung infection after liver transplantation and to construct a prediction model of early lung infection after liver transplantation.Methods The clinical data of 269 patients who underwent orthotopic liver transplantation for the first time were retrospectively analyzed.Patients were divided into the infected group(n=97)and the non-infected group(n=172)according to whether pulmonary infection occurred within 30 days after operation.The preoperative general data,preoperative laboratory examination results,intraoperative and postoperative data of the patients were collected.Multivariate Logistic regression analysis were used to screen risk factors of pulmonary infection.Based on the results of multivariate analysis,the prediction model was constructed and the prediction efficiency of the model was evaluated.Results Univariate and multivariate Logistic regression analysis showed that preoperative PNI≤41.70(OR=1.972,95%CI:1.047-3.714,P=0.036),LMR≤1.52(OR=2.020,95%CI:1.102-3.705,P=0.023),MELD score＞10.72(OR=1.985,95%CI:1.103-3.573,P=0.022),operative time＞448.00 min(OR=2.676,95%CI:1.515-4.727,P=0.001)and intensive care unit(ICU)hospitalization time＞4.0 days(OR=2.623,95%CI:1.335-5.154,P=0.005)were independent risk factors for early pulmonary infection after liver transplantation.The ROC area under the curve(AUC)of the prediction model based on the results of multivariate Logistic regression analysis was 0.768,the sensitivity was 80.41%and the specificity was 60.47%.Conclusion The prediction model based on PNI,LMR,MELD score,operation time and ICU hospitalization time can effectively predict the occurrence of early pulmonary infection after liver transplantation.

Objective To observe the progression of intestinal fibrosis in chronic radiation intestinal injury(CRII)and study the protective mechanisms of autophagy agonist rapamycin on intestinal fibrosis in CRII.Methods Thirty C57/B6male mice were randomly divided into the control group(CO group),the radiation group(SR group)and the rapamycin intervention group(RI group).The CO group was not treated.In SR group,the CRII model(single dose of9Gy radiation)was established first,and the samples were taken after 3months.In RI group,the rats were treated with rapamycin(2mg/kg,intraperitoneal injection)for 1 week after modeling,other treat-ments were the same as that in SR group.Hematoxylin-eosin staining and Masson staining were used to evaluate the degree of intestinal mucosal injury and intestinal fibrosis.Enzyme-linked immunosorbent assay was used to detect the serum levels of interleukin-1 β(IL-1β)and interleukin-6(IL-6).The level of intestinal α-smooth muscle actin(α-SMA)was detected by immunohistochemistry.The levels of transforming growth factor-β1(TGF-β1),connective tissue growth factor(CTGF)and autophagy-related proteins(p62 and LC3)were detected by Western blot.Results Histopathological staining showed that compared with CO group,the intestinal muco-sal damage was aggravated(P＜0.05),and the degree of intestinal fibrosis was increased in SR group(P＜0.01).Compared with SR group,the intestinal mucosal damages were relieved(P＜0.05),and the intestinal fibrosis was greatly decreased in RI group(P＜0.01).Compared with the CO group,the levels of IL-1 β and IL-6 in the SR group were significantly increased(P＜0.01),while those in the RI group significantly decreased compared with the SR group(P＜0.01).The results of immunohistochemistry and Western blot showed that the expression levels of α-SMA,TGF-β1 and CTGF in the SR group were greatly higher than those in the CO group(P＜0.05),while significantly lower in the RI group than those in the SR group(P＜0.05).The expression of autophagy indexes in SR group were lower than that in the CO group(P＜0.05),and significantly higher in the RI group than that in the SR group(P＜0.05).Conclusion Rapamycin-induced autophagy could improve the process of intestinal fibrosis in CRII,and the mechanism may be related to the inhibition the differentiation and function of intestinal myofibroblasts and reduce the inflammation of intestine.
