Objective To evaluate the efficacy of double percutaneous nephrostomy combined with ureter occlusion stent in treating cervical cancer complicated with vesicovaginal fistula after radiotherapy. Method A prospective analysis was taken for 12 patients with cervical cancer complicated with vesicovaginal fistula after radiotherapy who were diagnosed by gynecological examination, imaging and cystoscopy. All patients received concurrent double percutaneous nephrostomy and ureter occlusion stent implantation.The improvement of symptoms and postoperative complications were observed.The number of white blood cells in urine,renal function,number of diapers in daily use(pieces),daily vaginal and urethral exudate, pain score,physical status (ECOG) score and quality of life score (KPS) before and 7 d after the procedure were compare by the paired Student's t test. Results Twelve patients were successfully implanted 24 ureter occlusion stents after successful nephrostomy. Postoperatively, urinary fistula immediately disappeared in all patients.One week after operation,bilateral hydronephrosis disappeared in 4 patients, renal insufficiency and renal function returned to normal in 4 patients. There were significant differences in the number of white blood cells in urine,the number of diapers in daily use,the daily vaginal and urethral exudate,pain score,KPS and ECOG score compared with before and 7 d after the procedure(all P<0.05).There was no significant difference in the creatinine and urea nitrogen (all P>0.05). No serious complications occurred after the operation.Conclusion Double percutaneous nephrostomy combined with ureter occlusion stent can effectively and safely treat cervical cancer complicated with vesicovaginal fistula after radiotherapy.

Objective To investigate the safety and efficacy of camrelizumab added to second-line therapy after drug- eluting bead transarterial chemoembolization (DTACE) combined with apatinib for unresectable hepatocellular carcinoma (HCC). Methods A retrospective analysis was performed for 89 HCC patients with camrelizumab added to second-line therapy who attended The First Affiliated Hospital of Zhengzhou University from December 2019 to December 2020. The primary endpoints were overall survival (OS) and progression-free survival (PFS) after the application of camrelizumab, and the secondary endpoints were objective remission rate (ORR), disease control rate (DCR), and treatment-related adverse events (TRAEs). The Kaplan-Meier method was used to plot survival curves, the Log-rank test was used for stratified analysis of subgroups based on baseline characteristics, and the influencing factors for prognosis were analyzed. Results A total of 89 patients were screened and followed up in this study. The patients were followed up to December 2021, with a median follow-up time of 16 months, a median OS time of 17.0 (95% confidence interval [ CI ]: 15.3-18.7) months, and a median PFS time of 7.0 (95% CI : 6.2-7.8) months. There were significant differences in OS and PFS between the patients with different ECOG-PS scores, liver function Child-Pugh classes, portal vein invasion, patterns of progression, times of DTACE treatment, durations of oral administration of apatinib, and durations of application of camrelizumab (all P < 0.05). At 3 and 6 months after the application of camrelizumab, ORR was 39.3% and 22.4%, respectively, and DCR was 80.9% and 54.1%, respectively. The univariate analysis using the Log-rank test showed that compared with the patients receiving 0 time of DTACE treatment, the patients receiving 3-4 or 1-2 times of DTACE treatment had significant improvements in median OS [22.0 (95% CI : 21.1-22.9) months and 17.0 (95% CI : 15.8-18.2) months vs 10.0 (95% CI : 7.0-13.0) months, χ 2 =31.423, P < 0.001] and PFS [10.0 (95% CI : 7.0-13.0) months and 7.0 (95% CI : 6.2-7.8) months vs 3.0 (95% CI : 1.9-4.1) months, χ 2 =20.741, P < 0.001]; compared with the patients using apatinib for ≤4 months, the patients using apatinib for > 4 months had significant improvements in median OS [21.0 (95% CI : 19.1-22.9) months vs 14.0 (95% CI : 10.4-17.6) months, χ 2 =19.399, P < 0.001] and PFS [9.0 (95% CI : 7.3-10.7) months vs 5.0 (95% CI : 4.0-6.0) months, χ 2 =27.733, P < 0.001]; compared with the patients using camrelizumab for ≤5 months, the patients using camrelizumab for > 5 months had significant improvements in median OS [22.0 (95% CI : 20.2-23.8) months vs 13.0 (95% CI : 9.3-16.7) months, χ 2 =22.336, P < 0.001] and PFS [9.0 (95% CI : 7.0-11.0) months vs 5.0 (95% CI : 4.1-5.9) months, χ 2 =26.141, P < 0.001]. Post-embolization syndrome was the adverse event after DTACE and resolved after symptomatic treatment. Adverse reactions related to targeted drugs and immunotherapy all resolved after symptomatic supportive treatment, with no grade ≥4 adverse reactions, and no patients withdrew from target-free therapy due to TRAEs. Conclusion As for DTACE combined with apatinib in the treatment of unresectable HCC, camrelizumab added after progression has a marked therapeutic efficacy with safe and controllable TRAEs.

OBJECTIVE To study the effects of Zigui yichong formula on premature ovarian insufficiency (POI) in mice through glycolysis metabolic pathway. METHODS Eighty SPF C57BL/6N female mice were divided into normal group, model group, Zigui yichong formula group (14.175 g/kg), Zigui yichong formula+2-deoxy-D-arabino-hexose (2-DG) group (Zigui yichong formula 14.175 g/kg + glycolysis inhibitor 2-DG 100 mg/kg), with 20 mice in each group. Except for the normal group, POI model mice were induced by intraperitoneal administration of cyclophosphamide in the other groups. After the model was successfully established, each group was given corresponding drugs. HE staining was employed to observe the pathomorphological changes in ovarian tissue and to count follicles at all developmental stages; radioimmunoassay was conducted to measure the serum levels of estradiol (E2), anti-Müllerian hormone (AMH), and follicle-stimulating hormone (FSH); TUNEL assay was employed to detect apoptosis in ovarian granulosa cells of mice; the activities of hexokinase (HK), pyruvate kinase (PK) and lactate dehydrogenase (LDH) were detected by colorimetry; Western blot and real-time fluorescence quantitative PCR were employed to analyze the protein and mRNA expressions of B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), caspase-3, HK2, pyruvate kinase M2 (PKM2), and lactate dehydrogenase A (LDHA). RESULTS Compared with model group, the number of primordial follicles, growing follicles, antral follicles and granulosa cells were increased significantly(P<0.05), and granulosa cells arranged neatly, but the number of atretic follicles and granulosa cells apoptosis were decreased significantly in Zigui yichong formula group (P<0.05); the serum levels of E2 and AMH, the activities of HK, PK and LDH, protein and mRNA expressions of Bcl-2, HK2, PKM2 and LDHA were increased significantly (P<0.05); the serum levels of FSH, the protein and mRNA expressions of Bax and caspase-3, Bax/Bcl-2 ratio were decreased significantly (P<0.05). 2-DG could reverse the improvement effects of Zigui yichong formula on the above indexes of POI model mice. CONCLUSIONS Zigui yichong formula may inhibit the apoptosis of ovarian granulosa cells, reduce follicle atresia and improve ovarian reserve function by promoting glycolysis levels in POI model mice.
