Objective To investigate prognostic value of serum levels of cathepsin B(CTSB)and NADPH oxidase 4(NOX4)in patients with sepsis associated acute kidney injury(S-AKI).Methods A total of 306 pa-tients with sepsis treated to the hospital from June 2023 to June 2024 were selected,including 192 patients with S-AKI(S-AKI group)and 114 patients without S-AKI(non-S-AKI group).According to the prognosis of S-AKI patients,they were divided into poor prognosis group(n=127)and non-poor prognosis group(n=65).The differences of CTSB and NOX4 in different groups were compared.Pearson analysis was conducted to analyze the correlation between CTSB,NOX4 and clinical indicators.The influencing factors of poor prognosis in S-AKI patients was analyzed according to multivariate Logistic regression.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of CTSB and NOX4 on the poor prognosis of S-AKI pa-tients.Results Th e serum levels of CTSB,NOX4 and serum creatinine(SCr)in S-AKI group were signifi-cantly higher than those in non-S-AKI group(P＜0.05),while the mean arterial pressure and oxygenation in-dex were lower than those in non-S-AKI group(P＜0.05).Serum levels of CTSB and NOX4 in patients with sepsis were positively correlated with SCr(P＜0.05).Compared to non-poor prognosis group,the age,SCr,CTSB and NOX4 of patients in the poor prognosis group were higher,while the mean arterial pressure and ox-ygenation index were lower(P＜0.05).The increased mean arterial pressure and oxygenation index were pro-tective factors for poor prognosis in S-AKI patients(P＜0.05),and the increased age,SCr,CTSB and NOX4 levels were risk factors for poor prognosis in S-AKI patients(P＜0.05).ROC curve showed that the area un-der the curve(AUC)of CTSB combined with NOX4 was significantly higher than AUC of single detection of CTSB and NOX4(Z=4.066,P＜0.001,Z=3.801,P＜0.001).Conclusion The serum levels of CTSB and NOX4 in S-AKI patients are elevated,and can indirectly reflect kidney function.CTSB combined with NOX4 can significantly improve the prediction efficiency of poor prognosis in S-AKI patients,which has potential ap-plication value for clinical treatment and nursing.

Objective To investigate the expression and clinical significance of extracellular nicotinamide phosphate ribose transferase(eNAMPT)and soluble programmed death ligand 1(sPD-L1)in serum of pa-tients with sepsis secondary to severe pancreatitis(SAP).Methods A total of 92 SAP patients admitted to the hospital from February 2019 to February 2022 were selected as(SAP grou),and divided into a sepsis group(42 cases)and a non-sepsis group(50 cases).Moreover,50 patients with mild to moderate pancreatitis who were diagnosed and treated at the same time were selected as the disease control group,and 50 healthy in-dividuals who underwent the physical examination in the hospital during the same pariod were selected as the healthy control group.Enzyme linked immunosorbent assay was used to detect serum levels of eNAMPT and sPD-L1.Pearson correlation analysis was used for correlation analysis.Multivariate Logistic regression analy-sis was used to analyze factors affecting the occurrence of secondary sepsis in SAP.The predictive value of ser-um eNAMPT,sPD-L1 and their combination in the secondary sepsis of SAP was conducted by receiver operat-ing characteristic(ROC)curve.Results The serum levels of eNAMPT and sPD-L1 in the SAP group were higher than those in the disease control group and the healthy control group,and the differences were statisti-cally significant(P＜0.05).The Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score,Sequential Organ Failure Assessment(SOFA)score,white blood cell count,C-reactive protein,pancreatic nec-rosis,systemic inflammatory response syndrome,multiple organ failure,serum eNAMPT and sPD-L1 in the sepsis group were higher than those in the non-sepsis group,and the differences were statistically significant(P＜0.05).There was a positive correlation between serum eNAMPT,sPD-L1 and APACHE Ⅱ score,SOFA score in sepsis SAP patients(P＜0.05).Serum eNAMPT and sPD-L1 were independent risk factors for sec-ondary sepsis in SAP patients.The area under the curve(AUC)of the combination of serum eNAMPT and sPD-L1 for predicting secondary sepsis in SAP patients was 0.916(95％CI:0.868-0.947),which was signif-icantly larger than 0.846(95％CI:0.791-0.879)and 0.830(95％CI:0.774-0.861)of the single indicator detections,and the differences were statistically significant(Z=4.129,4.885,P＜0.001).Conclusion The serum eNAMPT and sPD-L1 levels in patients with sepsis secondary to SAP are elevated,which are related to the severity of the disease.The combination of serum eNAMPT and sPD-L1 has high predictive value for sec-ondary sepsis in SAP.

OBJECTIVE:To investigate the effects of rosuvastatin combined with berberine hydrochloride on related indexes in patients with acute cerebral infarction.METHODS:Medical information of 120 patients diagnosed as acute ischemic cerebral infarction were analyzed retrospectively,and they divided into observation group (65 cases) and control group (55 cases) according to route of administration.Both groups were given routine treatment;control group was additionally given Rosuvastatin calcium tablets 10 mg orally before bedtime,once a day;observation group was additionally given Berberine hydrochloride tablets 0.3 g orally,3 times a day,on the basis of control group.Treatment courses of 2 groups lasted for 14 d.The levels of TC,TG,LDL-C,HDL-C,hs-CRP,ox-LDL,NIHSS score,ADL score,TPA,IMT,Crouse score,the number of unstable plaque and ADR were observed and compared between 2 groups before and after treatment.RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups (P＞0.05).After treatment,the serum levels ofTC,TG,LDL-C,hs-CRP and ox-LDL in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P＜0.05).After treatment,NIHSS score of 2 groups were significantly lower than before,and ADL score,HDL-C levels were significantly higher than before,with statistical significance (P＜0.05);there was no statistical significance between 2 groups (P＞0.05).After treatment,there was no statistical significance in IMT,Crouse score and the number of unstable plaque in control group compared to before treatment (P＞0.05),but in observation group were significantly lower than before treatment,and also lower than control group at corresponding period,with statistical significance (P＜0.05).There was no statistical significance in TPA between 2 groups before and after treatment(P＞0.05).There was no statistical significance in the indcidence of ADR between 2 groups during treatment(P＞0.05).CONCLUSIONS:Based on routine treatment,rosuvastatin combined with berberine hydrochloride could effectively reduce blood lipid levels in patients with acute cerebral infarction,stabilize or reverse atherosclerotic plaque,and reduce inflammation and oxidative stress with good safety.
