Objective To explore the expression levels and clinical significance of serum angiopoietin-like protein 8(ANGPTL8),cardiotrophin like cytokine factor 1(CLCF-1)in patients with primary nephrotic syndrome(PNS).Methods 124 patients with PNS admitted to Yulin Hospital,the First Affiliated Hospital of Xi'an Jiaotong University from January 2020 to February 2023 were selected as the PNS group,and 60 healthy individuals who underwent physical examinations during the same period were selected as the control group.Enzyme linked immunosorbent assay(ELISA)was used to detect serum levels of ANGPTL8 and CLCF-1.The correlation between serum ANGPTL8,CLCF-1 and renal function indicators were analyzed by Pearson correlation analysis.Logistic regression analysis was used to analyze the influencing factors on the prognosis of PNS patients.The evaluation value of serum ANGPTL8 and CLCF-1 was analyzed by analyzing receiver operating characteristic curve.Results The serum ANGPTL8(22.16±3.27 μg/L),CLCF-1(89.71±11.04 ng/L),24-hour urine protein(5.79±1.45g/24h),blood urea nitrogen(10.20±1.41mmol/L)and blood creatinine(191.44±21.52μmol/L)in the PNS group were higher than those in the control group(3.08±0.46μg/L,14.20±3.78ng/L,0.09±0.03 g/24h,4.88±1.21mmol/L,70.34±11.26μmol/L),while blood albumin was lower than those in the control group(25.06±2.80g/L vs 42.11±3.37g/L),and the differences were statistically significant(t=25.088～51.109,all P＜0.001).Serum ANGPTL8 and CLCF-1 were positively correlated with 24-hour urine protein,blood urea nitrogen and blood creatinine(r=0.636～0.789,all P＜0.001),while negatively correlated with blood albumin(r=-0.712,-0.689,all P＜0.001).Compared with the good outcome group,the PNS patients in the poor outcome group had higher serum ANGPTL8,CLCF-1,while lower IgA,and the differences were statistically significant(t=24.403,12.455,5.974,all P＜0.001).Serum ANGPTL8,CLCF-1 were risk factors affecting the outcome of PNS patients,while IgA was a protective factor(Wald χ2=14.354,15.666,10.847,all P＜0.001).The AUC(95%CI)of the combined evaluation of serum ANGPTL8 and CLCF-1 for the outcome of PNS patients which was higher than that of serum ANGPTL8 and CLCF-1,and the differences were statistically significant(Z=4.265,4.810,all P＜0.001).Conclusion The expression of serum ANGPTL8 and CLCF-1 are elevated in PNS patients,which are related to renal function indicators.The combination of the two has high evaluation value for evaluating the prognosis of PNS patients.

Objective In this study,we tested different disinfectants and different action times to establish an efficient protocol for zebrafish embryo disinfection,which may in turn improve the management of zebrafish facilities.Methods We tested three reagents that can be used for embryo disinfection and are readily available in the domestic market:reagent-grade povidone-iodine,sodium hypochlorite,and chlorine dioxide.We evaluated the toxic effects of the reagents at three concentrations and two action times on zebrafish embryos at three stages,in term of survival,dechorioning,and malformation rates.The effects of the three disinfectants were also compared in terms of the amounts of embryos with surface bacteria after disinfection.Results Chlorine-containing disinfectants,i.e.sodium hypochlorite and chlorine dioxide,were better able to kill bacteria on the embryo surface,while povidone-iodine was not quite effective.Survival,dechorioning,and malformation rates were similar in embryos treated with 30 ppm sodium hypochlorite or chlorine dioxide to those in control embryos.Treatment with chlorine-containing disinfectants for 10 min were more effective in sterilizing than for 5 min.Conclusions The result of this study suggest treating 6～30 hpf embryos with 30 ppm sodium hypochlorite for 10 min as an operational method.

Objective:To explore the predictive value of ferritin combined with the COSSH-ACLF Ⅱ score for the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF).Methods:The clinical data of 419 cases with HBV-ACLF hospitalized at the Third Hospital of Hebei Medical University were retrospectively analyzed between January 1, 2013 and September 30, 2022, and were divided into the death ( n=127) and survival group ( n=292) according to the survival status of 28 days of follow-up. The Mann-Whitney U test was used to compare confirmation of non-normally distributed continuous data between two groups. The chi-square test was used for the comparison of numerical data between the two groups. Binary logistic regression analysis was used to analyze the independent risk factors affecting the prognosis of HBV-ACLF patients. The predictive value of ferritin combined with the COSSH-ACLF Ⅱ score on the prognosis of HBV-ACLF was evaluated by the receiver operating characteristic curve (ROC curve) and area under the curve (AUC), net reclassification index (NRI), and comprehensive discriminant improvement index (IDI). Results:There were statistically significant differences in age, neutrophil count (NEUT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), serum creatinine (Scr), serum urea, prothrombin time (PT), prothrombin activity (PTA), international normalized ratio (INR), serum ferritin (SF), hepatic encephalopathy, and COSSH-ACLF Ⅱ scores between the two groups ( P<0.05). Ferritin ( OR=1.001, 95% CI:1.001-1.002, P<0.001) and COSSH-ACLF Ⅱ score ( OR=2.898, 95% CI:1.560-5.384, P<0.001) were independent factors for predicting short-term prognosis for patients with HBV-ACLF. Ferritin combined with COSSH-ACLF II score had a higher prognostic predictive value than ferritin (AUC=0.697, 95% CI: 0.651-0.741) and COSSH-ACLF II score (AUC=0.819, 95% CI: 0.779-0.855) for patients with HBV-ACLF (AUC=0.857, 95% CI: 0.819-0.889), with a statistically significant difference ( Z=6.287 and 2.666, respectively, P <0.05). The predictive effect was significantly improved following the addition of ferritin to the COSSH-ACLF Ⅱ score ( P<0.001), and the NRI and IDI were both >0 (NRI=0.144, 95% CI: 0.064-0.225; IDI=0.080, 95% CI: 0.052-0.108). Conclusion:Ferritin and COSSH-ACLF Ⅱ scores are independent factors that can predict short-term prognosis for patients with HBV-ACLF, and combing both has a higher predictive value.

Objective:To compare the efficacy of lower extremity three dimensional CT venography (CTV) and lower extremity ascending phlebography in evaluating recurrent varicose veins.Methods:A retrospective analysis was conducted on clinical data from 235 patients with unilateral recurrent varicose veins who were treated at the Department of Vascular Surgery,Beijing Shijitan Hospital,Capital Medical University, between January 2015 and December 2020.There were 112 males and 123 females, with an age of (62.5±11.4)years (range:24 to 75 years).Patients were stratified into two groups based on preoperative imaging examination:the CTV group (utilizing lower extremity venous ultrasound+lower extremity CTV) and the control group (employing lower extremity venous ultrasound+lower extremity ascending phlebography).The two groups were matched in a 1∶1 ratio using propensity score matching, resulting in 43 cases per group.Comparative analyses between the groups at the one-year postoperative follow-up were performed using independent sample t tests, Wilcoxon rank-sum tests, χ2 tests, and linear regression analysis. Results:One year post-surgery,the CTV group exhibited a lower venous clinical severity score (VCSS) compared to the control group( M(IQR),3.0(4.3) vs.4.0(5.8), Z=-2.038, P=0.040).Additionally, the chronic venous insufficiency patients′ quality of life questionnaire (CIVIQ-20) scores were significantly higher in the CTV group than in the control group (89.0(8.0) vs.82.5(17.0), Z=-2.627, P=0.010).Patients in the CTV group also experienced a shorter ulcer healing time compared to the control group (4.0(4.0) weeks vs.12.0(7.0) weeks, Z=-3.217, P<0.01).Both groups showed no clinically symptomatic recurrent varicose veins or ulcers.However, they exhibited ultrasound-detectable varicose vein recurrence, with no statistically significant difference ( χ2=0.453, P=0.500).The number of diseased vessels requiring management based on ultrasound supplemented by CTV was 16, while the number supplemented by ascending phlebography was 7,with a statistically significant difference ( χ2=4.800, P=0.030).Linear regression analysis demonstrated that clinical-etiology-anatomy-pathology clinical grading and the preoperative imaging examination method exerted independent influences on VCSS and CIVIQ-20 during the one-year postoperative assessment. Conclusions:CTV-assisted ultrasound enables a direct and comprehensive evaluation and localization of diseased veins in patients with recurrent varicose veins.The utilization of lower extremity vein ultrasound combined with CTV-guided management of lower extremity vessels in minimally invasive treatment significantly improves patient prognosis, surpassing the assessment provided by ascending phlebography.

Objective:To evaluate the diagnostic evaluation process and the effectiveness and safety of intracavitary therapy for pelvic congestion syndrome (PCS).Methods:A retrospective analysis was conducted on 38 patients admitted to Beijing Shijitan Hospital affiliated to Capital Medical University from March 2019 to February 2022. Combined with the patient′s symptoms, PCS was diagnosed by color Doppler ultrasound, computed tomography venography (CTV), and venography. The ovarian vein was embolized with controllable spring coil and polydocanol foam sclerosing agent. The patients were followed up 1, 3 and 6 months after operation.Results:The total surgical success rate of 38 patients was 100%, and the incidence of complications was 5.3%(2/38); Spring coils (2.8±0.3)per person; The dosage of hardener was (7.0±2.1)ml/person. The improvement rate of patient symptoms was 97.4%(37/38); After 1, 3, and 6 months of surgery, color Doppler ultrasound was reexamined and no recanalization was observed in the embolized ovarian veins; The diameter of the parauterine vein was (2.8±0.5)mm, which was significantly lower than the preoperative (7.5±1.9)mm ( P<0.05); The Visual Analogue Scale (VAS) score was significantly lower than the preoperative score [(2.12±1.87)points vs (7.58±0.82)points, P<0.001]. Conclusions:Process based assessment is helpful in identifying and diagnosing PCS patients who urgently need treatment; Endovascular treatment based on embolization of ovarian vein with controllable spring coil and foam sclerosing agent is minimally invasive, safe and effective.

Objective:To analyze the risk factors of postoperative vitreous hemorrhage (PVH) after pars plana vitrectomy (PPV) for vitreous hemorrhage (VH) secondary to retinal vein occlusion (RVO).Methods:A retrospective case-control study. A total of 195 RVO patients (195 eyes) with VH were first treated with PPV from November 2015 to December 2021 were included in this study. There were 102 males (102 eyes) and 93 females (93 eyes), with an age of (62.93±9.78) years. The patients were divided into PVH group (17 patients, 8.72%) and non-PVH group (178 patients, 91.28%) according to the occurrence of PVH. The time of occurrence of PVH was (140.33±130.85) days after PPV. All eyes were performed 23G or 25G systematic PPV by the same doctor. During the operation, different types of intraocular tamponade and intravitreal injection of anti-vascular endothelial growth factor or triamcinolone acetonide after operation were selected according to the severity of retinopathy. The follow-up time was (9.45±6.68) months. The baseline systemic parameters, ocular parameters and intraoperative parameters affecting the occurrence of PVH were analyzed. Baseline systemic parameters included sex, age, diabetes mellitus and hypertension; ocular parameters included RVO type, lens status, VH course, preoperative best corrected visual acuity and intraocular pressure; intraoperative parameters included cataract phacoemulsification, removal of internal limiting membrane, type of intraocular tamponade, type of intravitreal injection drug at the end of operation, etc. Kaplan-Meier survival analysis, and Cox univariate and multivariate regression analysis were performed to analyze the risk factors of PVH after PPV in RVO with VH patients.Results:In PVH group, the number of patients with diabetes was more than that in the non-PVH group, and the course of diabetes was longer, and differences were statistically significant. There were significant differences in RVO type, lens status and type of intraocular tamponade. Univariate Cox regression analysis showed that the combination with diabetes [odds ratio ( OR)=2.724, 95% confidence interval ( CI) 1.006-7.374, P=0.049], duration of diabetes ( OR=1.071, 95% CI 1.013-1.134, P=0.016), central retinal vein occlusion ( OR=4.387, 95% CI 1.421-13.546, P=0.010), intraocular lens ( OR=3.493, 95% CI 1.229-9.925, P=0.019), and intraocular gas tamponade ( OR=3.640, 95% CI 1.365-9.702, P=0.010) were associated with PVH. Multivariate Cox regression analysis showed that intraocular gas tamponade was independent risk factor for PVH. Conclusion:Intraocular gas tamponade can increase the risk of PVH after PPV in patients with VH secondary to RVO.
