Objective:To study the effect of diabetes mellitus (DM) on sepsis in patients with pyogenic liver abscess (PLA).Methods:The clinical data of 116 patients with PLA treated in the Affiliated Hospital of Jiangnan University from January 2021 to May 2022 were retrospectively analyzed, including 64 males and 52 females, aged (62.3±12.6) years old. Patients were divided into DM group ( n=56) and non-DM group ( n=60), which were also divided into the sepsis group ( n=29) and the non-sepsis group ( n=87). The clinical features were compared among the groups, the risk factors of PLA complicated with sepsis were analyzed by multivariate logistic regression. Mediation model was used to analyze how DM affects the development of sepsis. Results:Compared with the non-DM group, patients in DM group had higher incidences of hypertension and acute physiology and chronic health evaluation II, a higher proportion of blood neutrophil count, a higher serum levels of triglyceride, urea nitrogen, fasting blood glucose and glycated hemoglobin at admission. The DM group also higher incidences of hypoproteinemia, pleural effusion, and sepsis, with longer hospital stay and higher hospitalization cost (all P<0.05). The levels of hemoglobin, albumin and hematocrit were lower in DM group (all P<0.05). Multivariate logistic regression analysis showed that comorbidity of DM ( OR=3.431, 95% CI: 1.245-9.455) and abscess with a larger diameter ( OR=1.664, 95% CI: 1.258-2.220) were associated with a higher risk of developing sepsis (all P<0.05). Mediation model showed that neutrophil count and triglyceride were the mediating variables of sepsis in patients with PLA. Conclusion:Comorbidity of diabetes is an independent risk factor of developing sepsis in patients with pyogenic liver abscess. Diabetes may induce sepsis by affecting the neutrophils and triglyceride.

Objective To investigate the clinical efficacy and safety of flexible ureteroscope combined with holmium laser in the treatment of upper urinary tract calculi(≥2.0cm).Methods One hundred patients with upper urinary tract calculi (≥2.0cm) were divided into control group and observation group according to random digits table method with 50 cases each.The control group was treated with percutaneous nephrolithotomy combined with holmium laser,and the observation group was treated with flexible ureteroscope combined with holmium laser.The operation related index, stone clearance rate and postoperative complications were compared between 2 groups.Results The operation time, two stage stone removal rate and length of hospital stay in observation group were significantly lower than those in control group:(45.76 ± 9.24)min vs.(52.12 ± 10.68)min,2.00%(1/50) vs.16.00%(8/50)and(4.46 ± 1.22)d vs.(5.73 ± 1.91)d,and there were statistical differences(P<0.01 or <0.05).The stone clearance rate in observation group was significantly higher than that in control group:94.59%(70/74)vs.81.69%(58/71),and there was statistical difference(P<0.05).There was no statistical difference in incidence of postoperative complications between 2 groups (P>0.05).Conclusions Flexible ureteroscope combined with holmium laser in the treatment of upper urinary tract calculi (≥2.0cm) can effectively reduce the reoperation rate, shorten the operation time and hospitalization time,and improve the stone clearance rate.The treatment is safe and effective.

Sarcopenia and physical deconditioning are common complications in patients with liver cancer,which are frequently caused by insufficient physical activity and poor nutritional status,resulting in physical frailty and a significant impact on the patient's physical fitness.Notably,sarcopenia,frailty,and poor cardiopulmonary endurance have all been linked to higher mortality rates among patients with liver cancer.Exercise intervention significantly improves various health parameters in liver cancer patients,including metabolic syndrome,muscle wasting,cardiorespiratory endurance,health-related quality of life,and reduction in hepatic venous pressure gradient.However,the link between physical exercise and liver cancer is commonly overlooked.In this article,we will examine the impact of exercise on liver cancer and present the most recent evidence on the best types of exercise for various stages of liver cancer.This article also summarizes and discusses the molecular mechanisms that control metabolism and systemic immune function in tumors.In brief,physical exercise should be considered an important intervention in the prevention and treatment of liver cancer and its complications.

Objective:To study the logistic regression model and Chi-square automatic interaction detection decision tree model in the prediction of the recurrence of acute pancreatitis (AP).Methods:Clinical data of 364 patients with AP admitted to the Affiliated Hospital of Jiangnan University from June 2021 to June 2022 were retrospectively analyzed, including 219 males and 145 females, aged 53 (19-91) years. The patients were divided into the recurrence group ( n=63), those who experienced a second or more episodes of AP, and the initial group ( n=301), those who were diagnosed of AP for the first time. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with recurrence of AP, and the decision tree model was used to analyze those factors. Receiver operating characteristic (ROC) curve were plotted to analyze the predictive performance of the two models. Results:Multivariate logistic regression analysis showed that age ( OR=0.969, 95% CI: 0.949-0.990, P=0.004), body mass index ( OR=1.142, 95% CI: 1.059-1.232, P=0.001), and hyperlipidemia ( OR=3.034, 95% CI: 1.543-5.964, P=0.001) were independent factors influencing the recurrence of AP. The accuracy of the model in predicting recurrence was 83.2% (303/364). The decision tree model showed that hyperlipidemia and body mass index were factors influencing the recurrence of AP, with an accuracy of 82.7% (301/364) in predicting recurrence. The area under the ROC curve was larger in the logistic regression model compared to that in the decision tree model (0.776 vs 0.730, Z=2.02, P=0.043). Conclusion:The logistic regression model and the Chi-square automatic interaction detection decision tree model can help predict the recurrence of AP. It is recommended to combine the two models to better guide clinical practice.
