Objective:To evaluate the effect of difference of fluid intake and excretion on the prognosis of elderly patients with septic shock during hospitalization in ICU, and to provide evidence for clinical assessment of the condition, prognosis prediction, and optimization of fluid resuscitation strategies during hospitalization.Methods:A retrospective cohort study was conducted, involving elderly septic shock patients admitted to the ICU of Zhoupu Hospital affiliated to Shanghai Health College from January 2018 to June 2024. Data on general characteristics, clinical parameters at 6 h and 24 h after ICU admission, and cumulative difference of fluid intake and excretion during ICU stay were collected. Patients were divided into survival group and death group based on whether they survived during hospitalization. Differences in study variables between groups were analyzed. Logistic regression analysis was performed on the independent risk factors of the mortality rate during hospitalization. Receiver operating characteristic (ROC) was plotted to evaluate the prognostic value of difference of fluid intake and excretion in elderly patients with septic shock during hospitalization in ICU.Results:A total of 159 elderly septic shock patients were included (108 males, 51 females), with an in-hospital mortality rate of 66.66% (106 deaths vs. 53 survivors). Compared with the survival group, the difference of total fluid intake and excretion during hospitalization in ICU in the death group was significantly lower [2 441.00 (228.50, 5 101.50) mL vs. 6 215.50 (3 755.00, 9 874.75) mL, P<0.001]. Multivariate logistic regression analysis showed that SOFA score ( OR=1.359, 95% CI: 1.135-1.626, P=0.001) and the difference of total fluid intake and excretion during hospitalization in ICU ( OR=1.174, 95% CI: 1.067-1.291, P=0.001) were independent risk factors for predicting prognosis during hospitalization. ROC analysis revealed that the cumulative difference of fluid intake and excretion achieved an AUC of 0.756 (95% CI: 0.674-0.838, P<0.001), with a sensitivity of 61.8% and specificity of 82.4% at a cutoff value of ≥5 396.5 mL. In addition, AUC of the total fluid intake and excretion difference and SOFA score during hospitalization in ICU was 0.885 (95% CI: 0.825-0.944, P<0.001). Conclusions:A higher cumulative difference of fluid intake and excretion during ICU hospitalization is associated with increased mortality in elderly septic shock patients. A positive difference of fluid intake and excretion may serve as a clinical indicator for predicting prognosis of elderly patients with septic shock.

Objective To compare the clinical efficacy of modified multi-side hole nasobiliary drainage(MHND)via the percuta-neous transhepatic cholangiography(PTC)route with traditional percutaneous transhepatic cholangial drainage(PTCD)for palliative treatment of patients with advanced obstructive cholangiocarcinoma.Methods A retrospective analysis was conducted on the data from 66 patients with advanced cholangiocarcinoma who underwent biliary drainage.Results Both groups normalize temperature and alleviate symptoms of acute cholangitis within 24 h post-puncture.There was no statistically significant difference in laboratory indicators such as white blood cell(WBC),total bilirubin(TBiL),alanine transaminase(ALT),aspartic transaminase(AST)at 48 h post-operation,and in the incidence of bile leakage,biliary peritonitis,and cholangitis during the postoperative hospital stay(P>0.05).However,the incidence of postoperative electrolyte disorders,gastrointestinal symptoms,and the recurrence rate of gastrointestinal symptoms during the follow-up period were significantly higher in the PTCD group compared to the MHND group,while the recur-rence rate of biliary tract infections was slightly higher in the MHND group compared to the PTCD group.The differences between the two groups were statistically significant(P<0.05).Conclusion Modified MHND shows better clinical efficacy in the treatment of patients with advanced tumor jaundice.Compared with traditional PTCD,it not only effectively reduces jaundice and relieves acute cholangitis but also significantly reduces gastrointestinal symptoms during the postoperative period,thereby improving the quality of life for patients.However,it is noteworthy that it may also increase the risk of biliary tract infections.

Background and Aims:Complex choledocholithiasis often coexists with stenosis of the ampulla of Vater,which increases the difficulty and complexity of treatment.If only the stones in the bile duct are removed without addressing the ampullary stenosis,the disease is prone to recurrence.Previously,most treatments involved the use of endoscopic retrograde cholangiopancreatography(ERCP)to guide the wire for sphincterotomy and stone extraction,followed by laparoscopic cholecystectomy.However,ERCP has limitations in handling complex cases.In response,our team pioneered a new method of treating choledocholithiasis combined with stenosis of the ampulla of Vater via a transabdominal approach.This study was performed to investigate the feasibility and efficacy of this method,aiming to provide a new therapeutic option for clinical practice.Methods:A randomized controlled study was conducted with 120 patients treated at Chengdu Second People's Hospital from 2021 to 2023 for gallbladder stones and choledocholithiasis with stenosis of the ampulla of Vater.Patients were divided into an observation group and a control group,with 60 cases in each group.The observation group underwent laparoscopic cholecystectomy with choledochotomy for stone extraction,followed by retrograde guidance of duodenal papillary sphincterotomy through the opened bile duct,simultaneously treating gallbladder,bile duct stones,and stenosis of the ampulla of Vater.The control group underwent traditional ERCP approach for sphincterotomy,stone extraction,and laparoscopic cholecystectomy.Perioperative variables were collected for both groups and the surgical outcomes were compared.Results:Among the 120 patients,54 were male and 66 were female.There were no statistically significant differences between the two groups in terms of stone extraction success rate,intraoperative blood loss,postoperative 24-h total bilirubin,direct bilirubin,transaminases,white blood cell count,jaundice relief time,or incidence rates of bile leakage,retroperitoneal bleeding/infection,and severe pancreatitis(all P>0.05).The observation group had significantly shorter average operative time and postoperative hospital stay compared to the control group(98.67 min vs.110.8 min,P<0.05;3.81 d vs.5.61 d,P<0.05).Additionally,the observation group had a significantly lower incidence of postoperative hyperamylasemia and/or hyperlipasemia and mild pancreatitis(1.67%vs.25.00%,P<0.001;0 vs.10%,P=0.027).Conclusion:The novel transabdominal approach is superior to the ERCP approach in terms of reducing surgery time and hospitalization time,and it carries a lower risk of postoperative mild pancreatitis and hyperamylasemia and/or hyperlipasemia.The stone extraction success rate is comparable to that of ERCP,making it a viable alternative treatment option.

Objective:To investigate the prognostic value of albumin (ALB), aspartate aminotransferase/alanine aminotransferase ratio (AST/ALT) in patients with acute liver failure (ALF) in hyperacute phase of sepsis which provided the basis for clinical evaluation and prognostic judgment and corresponding treatment options.Methods:A multicenter retrospective cohort study was conducted. Patients with ALF in hyperacute phase of sepsis admitted to Zhoupu Hospital Affiliated to Shanghai Health College, Shanghai Pudong New Area People's Hospital, and Shanghai Oriental Hospital from January 2019 to February 2024 were enrolled. General data such as gender and age of the patients were collected. Lactate dehydrogenase (LDH), liver function indexes [total bilirubin (TBIL), direct bilirubin (DBIL), AST, ALT, AST/ALT, ALB, total protein (TP), globulin (GLB), ALB/GLB ratio (A/G), blood amine, γ-glutamyl transpeptidase (γ-GT)], platelet count (PLT), creatinine, activated partial thromboplastin time (APTT), severity of illness scores [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), sequential organ failure assessment (SOFA)], serum procalcitonin (PCT), N-terminal pro-brain natriuretic peptide (NT-proBNP), arterial blood lactic acid (Lac) within 24 hours after admission, and whether to use mechanical ventilation, whether to use vasoactive drugs, whether to use artificial liver treatment and prognosis during hospitalization also were collected. The differences of clinical data between patients with different prognosis were compared. The variables with statistically significant differences in univariate analysis were included in multivariate Logistic regression analysis to determine the independent risk factors for death of patients with ALF in hyperacute phase of sepsis during hospitalization. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of ALB and AST/ALT for death of patients with ALF in hyperacute phase of sepsis during hospitalization.Results:A total of 73 patients with ALF in hyperacute phase of sepsis were included, with 22 survived and 51 died during hospitalization and the mortality of 69.86%. Compared with the survival group, the patients in the death group had lower ALB, γ-GT within 24 hours after admission and proportion of artificial liver treatment, and higher AST/ALT, SOFA score, LDH and proportion of use of vasoactive drugs. The differences were statistically significant. Multivariate Logistic regression analysis showed that ALB and AST/ALT were the independent risk factors for death in patients with ALF in hyperacute phase of sepsis during hospitalization [ALB: odds ratio ( OR) = 0.856, 95% confidence interval (95% CI) was 0.736-0.996, P = 0.044; AST/ALT: OR = 2.018, 95% CI was 1.137-3.580, P = 0.016]. ROC curve analysis showed that the area under the curve (AUC) of ALB for predicting in-hospital death in patients with ALF in hyperacute phase of sepsis was 0.760 (95% CI was 0.637-0.884, P < 0.001). When ALB ≤ 29.05 g/L, the sensitivity was 68.2%, and the specificity was 76.5%. The AUC of AST/ALT for predicting in-hospital death in patients with ALF in hyperacute phase of sepsis was 0.764 (95% CI was 0.639-0.888, P < 0.001). When AST/ALT ≥ 1.26, the sensitivity was 59.1%, and the specificity was 90.2%. Conclusions:The lower the ALB level, and the higher the AST/ALT within 24 hours after admission, the worse the prognosis of patients with ALF in hyperacute phase of sepsis. ALB and AST/ALT can be used as clinical indicators to evaluate the severity and prognosis of patients with ALF in hyperacute phase of sepsis.

Objective:To investigate the prognostic value of cardiac ultrasound left ventricular ejection fraction (LVEF) on admission in patients with septic cardiomyopathy.Methods:A retrospective cohort study was conducted. The patients with septic cardiomyopathy hospitalized in the intensive care unit of Zhoupu Hospital Affiliated to Shanghai Health College from January 2019 to March 2023 were enrolled. The general information including gender and age, LVEF on admission, severity of illness scores within 24 hours after admission [acute physiology and chronic health evaluationⅡ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score], procalcitonin (PCT), cardiac biomarkers [N-terminal pro-brain natriuretic peptide (NT-proBNP), cardiac troponin T (cTnT), and MB isoenzyme of creatine kinase (CK-MB)], mitochondria related indicators [aspartate aminotransferase (AST), AST/alanine aminotransferase (ALT) ratio], blood lactate (Lac), the usage of vasoactive drugs and mechanical ventilation, and the prognosis during hospitalization were collected. The differences in above clinical data between the two groups were compared. The variables with statistically significant differences in univariate analysis were incorporated into multivariate Logistic regression analysis to analyze the independent risk factors for death during hospitalization in patients with septic cardiomyopathy. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the prognostic value of LVEF by echocardiography on admission in patients with septic cardiomyopathy during hospitalization.Results:A total of 62 patients were enrolled, including 36 males and 26 females. Thirty-nine cases died and 23 cases survived during hospitalization, and the mortality was 62.90%. Compared with the survival group, the LVEF of patients on admission was lower in the death group [0.51 (0.40, 0.57) vs. 0.56 (0.51, 0.63), P < 0.01], APACHEⅡ score, SOFA score, Lac, NT-proBNP, CK-MB within 24 hours after admission were higher [APACHEⅡ score: 22.18±8.38 vs. 17.39±8.22, SOFA score: 9.90±3.87 vs. 7.09±3.27, Lac (mmol/L): 5.10 (2.63, 11.50) vs. 2.00 (1.40, 5.00), NT-proBNP (μg/L): 5.24 (2.84, 11.29) vs. 2.53 (0.35, 6.63), CK-MB (U/L): 1.88 (0.21, 5.33) vs. 0.17 (0.02, 1.62), all P < 0.05], and the proportion of vasoactive drug application was higher (82.05% vs. 47.83%, P < 0.01). Multivariate Logistic regression analysis showed that LVEF on admission was an independent risk factor for predicting the prognosis of patients with septic cardiomyopathy during hospitalization [odds ratio ( OR) = 0.920, 95% confidence interval (95% CI) was 0.855-0.990, P = 0.025]. ROC curve analysis showed that the area under the ROC curve (AUC) of LVEF on admission for predicting the death of patients with septic cardiomyopathy was 0.715 (95% CI was 0.585-0.845, P = 0.005). When LVEF ≤ 0.52, the sensitivity was 73.9%, and the specificity was 61.5%. Conclusions:The lower cardiac ultrasound LVEF on admission, the worse the prognosis of patients with septic cardiomyopathy. The cardiac ultrasound LVEF on admission can be used as a clinical index to evaluate the severity of the condition and predict the prognosis of patients with septic cardiomyopathy.

Objective:To evaluate the prognostic value of Karnofsky performance scores (KPS) in elderly patients with sepsis, so as provide a basis for clinical evaluation of the condition, prognosis and corresponding treatment measures.Methods:A retrospective cohort study was conducted to collect the general information, clinical data, and follow-up data of limb motor function status and self-care ability of elderly patients with sepsis who were hospitalized in the Intensive Care Unit of our hospital from January 2018 to June 2021. Patients were divided into the survival group and death group according to whether they survived the hospitalization. Statistical analysis was performed using t-test, chi-square test, and Mann-Whitney test. The KPS score before admission, disease severity scores (APACHEⅡ and SOFA), serum procalcitonin (PCT), N-terminal pro-brain natriuretic peptide (NT-proBNP), and arterial blood lactate level on admission were compared between the two groups. Then, the factors with significance in univariate analysis were analyzed by Logistic regression method, the independent risk factors for predicting in-hospital mortality were determined, and the receiver operating characteristic (ROC) curve was drawn to evaluate the prognostic value of KPS score in elderly patients with sepsis.Results:A total of 135 patients were collected. There were 85 males and 50 females, 60 died and 75 survived during hospitalization, with a mortality rate of 44.4%. The preadmission KPS score of elderly patients with sepsis in the death group was significantly lower than that in the survival group [30 (30, 40) vs. 70 (50, 90), P<0.001]. Multivariate logistic regression analysis showed that KPS score ( OR=0.938, 95% CI: 0.914-0.963, P<0.001), SOFA score ( OR=1.255, 95% CI: 1.066-1.451, P=0.002) and arterial blood lactate ( OR=1.219, 95% CI: 1.059-1.404, P=0.006) were independent risk factors for predicting the prognosis during hospitalization. ROC curve analysis of mortality showed that compared with SOFA score and blood lactate, the area under the curve of KPS score was the largest, with AUC of 0.830 (95% CI: 0.756-0.890, P<0.001). In addition, the combination of KPS, SOFA and blood lactate had a greater predictive value for the prognosis of elderly patients with sepsis than that of the single index, with an AUC of 0.883 (95% CI: 0.826-0.940, P<0.001). Conclusions:The lower the KPS score, the worse the prognosis of elderly patients with sepsis. The KPS score can be used as a clinical indicator to predict the prognosis of elderly patients with sepsis.

Objective To investigate the influence of high-level of glucose on the expression of ghrelin in human umbilical vein endothelial cells (HUVECs). Methods After 12 h glucose free culturing, the effects of different concentrations of glucose and different incubation times on expressions of ghrelin were observed in HUVECs. ( 1) The cells were treated with 0, 5, 10, 15, 20 mmol/L glucose for 2 h, then ghrelin mRNA expression levels were detected by RT-PCR, and the protein levels of ghrelin were detected by ELISA. (2) The cells were treated with 10 mmol/L glucose for 0, 0.5, 1, 2, 6, 12 hours, ghrelin mRNA and protein levels were detected respectively. Results (1) The expression levels of ghrelin mRNA and protein decreased along with increased glucose concentrations, which showed no obvious changes when the glucose was above 15 mmol/L. (2) The expression levels of ghrelin mRNA and protein decreased with the prolonged incubation time. But more than 6 h culturing time showed no further effect on reducing the expression level of ghrelin. Conclusion High levels of glucose can inhibit the expression level of ghrelin, which may be one of the mechanisms of atherosclerosis.

Objective To observe the effects of antiplatelet drugs on the incidence of no reflow,main adverse cardiovascular and cerebrovascular events (MACCE) after percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD).Methods From January 2010 to February 2011,a total of 84 CHD patients with no-reflow after PCI were selected and randomly divided into observed group and control group (n=42 each group).Patients with no/slow-reflow in observed group were injected with tirofiban through coronary artery with a guiding catheter.If invalid,patients were injected with tirofiban by catheterization again with a micro-pump continuous pumping for 24 h.Patients with no/slow reflow in control group were injected with verapamil by catheterization.If invalid,patients were injected with verapamil by catheterization again.Results The numbers of patients with Thrombolysis in Myocardial Infarction (TIMI) 3 in the first and last angiography after drug administration were much more in observed group than in control group [26 cases (61.9％) vs.17 cases (40.5％),35 cases (83.3％) vs.23 cases (54.8％),respectively,x2 =3.86,8.02,both P＜0.05].The first TIMI frame count (TFC) after drug administration was significantly lower in observed group than in control group,and the difference between groups became larger in the last TFC (t=-3.44,-12.41,both P＜0.05).The number of patients with TIMI myocardial perfusion grade (TMPG) 3 in the first and last angiography after drug administration were much more in observed group than in control group [24 cases (57.1％) vs.13 cases (31.0％),31 cases (73.8％) vs.20 cases (47.6％),respectively,x2=5.84,6.04,both P＜0.05].After 60 days of follow up,there was a significant difference in the incidence of endpoint events between observed and control group [23.8％ (10 cases) vs.52.3％ (12 cases),x2 =7.27.P＜0.01].The predisposing factors of no reflow were age,acute myocardial infarction (AMI),diabetes,hyperlipidemia and hypertension.Conclusions Tirofiban can effectively and safely reduce the incidence of no-reflow after percutaneous coronary intervention in patients with CHD.
