ObjectiveTo verify the therapeutic effect of Yinqi Sanhuang Jiedu decoction （YQSH） on carbon tetrachloride （CCl₄）-induced hepatic fibrosis in mice， and to explore whether its effect was related to the inhibition of neutrophil infiltration and the formation of neutrophil extracellular traps （NETs）. MethodsThe 36 C57BL/6J mice were randomly divided into control group， model group， positive drug silybin （SF） group （55 mg·kg^-1·d^-1）， YQSH-L group， YQSH-M group， and YQSH-H group （8.325， 16.65， 33.3 g·kg^-1·d^-1， respectively），n=6 in each group. Except for the control group， mice in all other groups were intraperitoneally injected with CCl₄ to induce hepatic fibrosis. After successful modeling， each drug administration group was given the corresponding drugs by gavage for eight weeks. Hematoxylin-eosin （HE） staining， Sirius red staining and Masson staining were used to observe the pathological changes of liver tissue. Liver elasticity was detected by a color Doppler ultrasound system. Immunohistochemistry and real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） were performed to detect the protein expression and mRNA levels of C-X-C motif chemokine ligand 1 （CXCL1）， CXCL2 and CXCL5. Neutrophil levels were detected by flow cytometry. The expression of neutrophil elastase （NE） and myeloperoxidase （MPO） positive protein was observed by immunofluorescence. The contents of MPO， NE and CitH3 were detected by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the control group， the liver of the model group showed obvious inflammatory cell infiltration and collagen deposition， and the liver elasticity， CXCL1， CXCL2， CXCL5 expression， neutrophil level， and MPO， NE and CitH3 levels were significantly increased （P<0.05， P<0.01）. Compared with the model group， inflammatory cell infiltration and collagen deposition in the liver tissue of mice were reduced after YQSH treatment. Moreover， the liver elasticity was reduced （P<0.01）. The protein expression （P<0.01） and mRNA level of CXCL1， CXCL2 and CXCL5 were decreased（P<0.05，P<0.01）. The neutrophil level was decreased （P<0.01）， the expression of MPO and NE positive protein was significantly decreased（P<0.05，P<0.01）， and the levels of MPO， NE and CitH3 were decreased （P<0.05， P<0.01）. ConclusionThe anti-hepatic fibrosis effect of YQSH may be related to its inhibition of chemokines （CXCL1， CXCL2， CXCL5）， reduction of neutrophil infiltration， and inhibition of NETs generation.

Objective:To summarize and analyze the modalities and experience of retrograde distal perfusion with distal perfusion catheter (DPC) via cannulation of the posterior tibial artery in veno-arterial extracorporeal membrane oxygenation(V-A ECMO).Methods:The clinical data of 15 patients who were treated with V-A ECMO and underwent DPC placement via the posterior tibial artery in our hospital from January 2022 to June 2023 were retrospectively analyzed.Results:The V-A ECMO catheterization method in 15 patients was percutaneous puncture catheterization, and all of them underwent surgical incision to indwelling retrograde DPC through the posterior tibial artery: 6 cases of preventive catheterization, 9 cases of remedial catheterization, the success rate of one-time catheterization was 93.33%, and the type of catheter was mainly 6 F sheath (66.67%). There was no ALI in preventive catheterization, and one case of osteofascial compartment syndrome occurred in remedial catheterization, and the catheterization time was (20.73 ± 3.47) min.Conclusions:In V-A ECMO, placement of DPC via the posterior tibial artery for retrograde distal perfusion is perfectly feasible, and has a high success rate, which can prevent or treat lower extremity ischemia.

Objective To explore the mediating role of depression between uremic toxins and cognitive function in end-stage renal disease(ESRD)patients,so as to provide a basis for early clinical intervention.Methods A retrospective study involved 49 predialysis ESRD patients diagnosed in the Nephrology Department of The First Affiliated Hospital of Xi'an Jiaotong University between August 2018 and October 2021,along with 50 healthy controls(HC).General information of the two groups was collected.Montreal Cognitive Assessment(MoCA),Auditory Verbal Learning Test-Huashan Version(AVLT-H),Trail Making Test A(TMT-A),Beck Depression Inventory(BDI),and Beck Anxiety Inventory(BAI)were used to collect data on cognitive function,anxiety,and depression in both groups.Serological indicators in the ESRD group were used to clarify the impact of uremic toxins on cognitive function.PROCESS v3.4.1 was applied to explore the relationship between uremic toxins,depression,and cognitive function,as well as the mediating effect of depression.Results Significant differences were found between the ESRD group and the HC group in MoCA total score(P＜0.001),AVLT-H(word learning;short-term delay;long-term delay,P＜0.001;word recognition,P=0.001),TMT-A(P＜0.001),BDI(P＜0.001),and BAI(P=0.009).Cystatin C was a negative influencing factor for short-term delay in AVLT-H(B＝-0.834,P=0.019),while BDI was a negative influencing factor for long-term delay in AVLT-H(B=-0.102,P=0.002),word recognition in AVLT-H(B=-0.071,P＜0.001),and MoCA total score(B=-0.135,P=0.002).BDI partially mediated the effect of cystatin C on short-term delay in AVLT-H(total effect,c=-0.3346;direct effect,c'=-0.223 5;mediating effect,a×b=-0.111 0;and mediating effect proportion,33.2％)and long-term delay in AVLT-H(total effect,c=-0.318 7;direct effect,c'=-0.218 8;mediating effect,a×b=-0.099 9;and mediating effect proportion,31.3％).Conclusion ESRD patients experience cognitive decline as well as anxiety and depression.Cystatin C and depression are both negative influencing factors for cognitive decline in ESRD patients.Cystatin C indirectly affects cognitive function in ESRD patients through depression.

Objective:To investigate the change of D-Dimer (D-D), cardiac troponin I (cTnI) and vasoactive-inotropic score (VIS) after Stanford type A aortic dissection (TAAD) and thier predictive effect on death outcome.Methods:120 patients with TAAD who were treated in the Affiliated Hospital of Jining Medical College from January 2019 to January 2022 were retrospectively selected and divided into death group ( n=17) and survival group ( n=103) according to the 28-day survival after operation. The difference of clinical data between the two groups was compared, and the influencing factors of postoperative death in TAAD patients were analyzed by logistic regression method. Results:The age, deep hypothermic circulatory arrest time, D-D and cTnI of the patients in the death group were (60.50±5.42)years old, (30.40±9.92)min, (15.65±5.52)g/L and (3.32±0.82)mg/L, respectively, which were significantly higher than those in the survival group (all P<0.05). The VIS score and change of VIS score in the death group at 24 hours after operation were (9.66±1.10)points and (4.50±0.91)points respectively, which were significantly higher than those in the survival group (all P<0.05). Logistic regression analysis showed that age, D-D, cTnI and change of VIS score were the influencing factors of death after TAAD (all P<0.05). The area under the receiver operating characteristic (ROC) curve predicted by the D-D, cTnI and change of VIS score for death in TAAD patients was 0.718, 0.691 and 0.789 respectively (all P<0.05). Conclusions:Postoperative death of TAAD patients is affected by their age, D-D, cTnI and change of VIS score. The D-D, cTnI and change of VIS score have certain application value in predicting postoperative death of patients.

ObjectiveTo observe the effect of aerobic exercise on core symptoms and executive function in children with attention deficit hyperactivity disorder (ADHD). MethodsFrom June, 2020 to December, 2021, 64 children with ADHD at outpatient in Dushu Lake Hospital were randomly divided into control group (n = 32) and observation group (n = 32). The control group sat down and watched the cartoon for 20 minutes, and the observation group performed cycling exercise while watching the cartoon, for twelve weeks. The core symptoms were assessed with Conners Parent Symptom Questionnaire (PSQ), while the inhibition, conversion and refresh functions were assessed with the psychological test software E-Prime 2.0 system. ResultsAfter twelve weeks of treatment, the PSQ factor scores decreased in the observation group (t > 4.775, P < 0.001), and were lower than that of the the control group (t > 3.184, P < 0.001). The response time and accuracy of inhibition, conversion, and refresh functions decreased in the observation group (t > 2.259, P < 0.05), and were lower than that of the control group (t > 2.007, P < 0.05). ConclusionAerobic exercise could reduce the core symptoms of poor attention and hyperactivity impulsivity, and improve the executive functioning in children with ADHD.

Objective To investigate the risk factors for rebleeding after emergency esophageal variceal ligation (EVL) in patients with liver cirrhosis. Methods A retrospective analysis was performed for the clinical and laboratory data of 290 patients with liver cirrhosis who underwent emergency EVL in The Fifth Medical Center of Chinese PLA General Hospital from January 2016 to December 2019, and according to the presence or absence of rebleeding within 1-year follow-up, they were divided into rebleeding group and non-rebleeding group. The t -test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A multivariate logistic regression analysis was performed with the statistically significant factors as independent variables to screen out the independent risk factors for rebleeding after emergency EVL, and the receiver operating characteristic (ROC) curve was plotted to obtain the indices for predicting the probability of rebleeding and establish a predictive model. Results The univariate analysis showed that there were significant differences between the two groups in platelet count ( t =-1.888, P =0.047), Child-Pugh score ( χ 2 =5.975, P =0.049), albumin level ( t =-2.229, P =0.029), and splenic vein diameter ( t =3.808, P =0.001). The multivariate logistic regression analysis showed that Child-Pugh score (odds ratio [ OR ]=0.280, 95% confidence interval [ CI ]: 0.108-0.729, P =0.009), splenic vein diameter ( OR =1.549, 95% CI : 1.197-2.005, P =0.001) and albumin level ( OR =0.832, 95% CI : 0.729-0.949, P =0.006) were independent influencing factors for rebleeding after EVL. The predictive model based on these three factors had an area under the ROC curve of 0.796, with a sensitivity of 83.7% and a specificity of 74.5% at the cut-off value of -0.086. Conclusion Child-Pugh score, albumin level, and splenic vein diameter are independent risk factors for rebleeding after emergency EVL, and the combination of the three indices has the highest sensitivity and specificity in predicting rebleeding.

Objective: To observe the effect of atorvastatin combined with insulin glargine on renal function in patients with early diabetic nephropathy. Methods: From January 2016 to March 2019, 100 patients with early diabetic nephropathy admitted to Hanzhong 3201 Hospital Affiliated with Xi′an Jiaotong University Medical School were selected as subjects. According to the random number table, patients were divided into control group and observation group, with 50 cases in each group. All patients underwent diet control, blood pressure control and symptomatic treatment. Patients in the control group were treated with insulin glargine to control blood glucose. Patients in observation group were given atorvastatin on this basis. After 16 weeks of treatment, the therapeutic effects of the two groups were observed, as well as the change in urinary albumin excretion rate (UAER), serum creatinine (Scr), C-reactive protein (CRP), total cholesterol (TC), and triglyceride (TG). Adverse reactions were observed during treatment in both groups. Results: After treatment, the levels of UAER, Scr, CRP, TC and TG of the two groups were lower than those before treatment, and the above indexes of the observation group were lower than those of the control group. The difference were statistically significant (P<0.05). During the treatment period, the incidence of adverse reactions in control group and observation group was 4.00%(2/50) and 12.00%(6/50), and there was no significant difference (P>0.05). Conclusions Atorvastatin combined with insulin glargine in the treatment of early diabetic nephropathy can effectively reduce the levels of UAER, Scr, CRP, TC and TG, and has good safety.
