Objective:To investigate the differences in prognosis between different surgical approaches in elderly patients with advanced ovarian cancer.Methods:Based on the Surveillance, Epidemiology and End Results (SEER) database, a cohort of elderly patients with advanced ovarian cancer from 2000 to 2020 was established. Through propensity score matching, 2 094 patients were selected from those who underwent two different surgical approaches to form a matched cohort (SEER database cohort), including 1 039 patients who received cytoreductive surgery and 1 055 patients who underwent local resection. Meanwhile, 148 elderly patients with advanced ovarian cancer who were treated at the First Affiliated Hospital of Shandong First Medical University from January 2012 to January 2024 were selected (hospital cohort), among whom 85 underwent cytoreductive surgery and 63 underwent local resection. The prognostic differences among patients who underwent cytoreductive surgery and local resection in two cohorts and stratified by the International Federation of Gynecology and Obstetrics (FIGO) staging were evaluated, respectively. The relationship between the causes of death and surgical approaches in elderly patients with advanced ovarian cancer was analyzed.Results:In the SEER database cohort, the median overall survival (OS) for patients who underwent cytoreductive surgery and local resection was 37 and 40 months, respectively, with 5-year OS rates of 31.47% and 33.74%, with no statistically significant difference ( χ2=0.78, P=0.378). After stratification by FIGO staging, the median OS for patients with stage ⅢB-ⅢC who underwent cytoreductive surgery ( n=998) and local resection ( n=962) was 38 and 40 months, respectively, with no statistically significant difference ( χ2=0.20, P=0.659). For patients with stage Ⅳ, the median OS for those who underwent cytoreductive surgery ( n=41) and local resection ( n=93) was 17 and 36 months, respectively, with a statistically significant difference ( χ2=9.37, P=0.002). Among 2 094 elderly patients with advanced ovarian cancer, 1 581 had clearly identified causes of death. In patients who underwent cytoreductive surgery, the proportions of deaths due to ovarian cancer and non-ovarian cancer were 94.52% (742/785) and 5.48% (43/785), respectively. In patients who underwent local resection, the proportions of deaths due to ovarian cancer and non-ovarian cancer were 91.46% (728/796) and 8.54% (68/796), respectively. There was a statistically significant difference in the distribution of causes of death between the two surgical approaches ( χ2=5.69, P=0.017). In the hospital cohort, the median OS for patients undergoing cytoreductive surgery and local resection was 39 and 51 months, respectively, with 5-year OS rates of 22.85% and 23.81%, with a statistically significant difference ( χ2=6.71, P=0.010). After stratification by FIGO staging, the median OS for patients with stage ⅢB-ⅢC undergoing cytoreductive surgery ( n=29) and local resection ( n=26) was 50 and 51 months, respectively, with no statistically significant difference ( χ2=0.15, P=0.699) ; for patients with stage Ⅳ undergoing cytoreductive surgery ( n=56) and local resection ( n=37), the median OS was 35 and 47 months, respectively, with a statistically significant difference ( χ2=6.55, P=0.011) . Conclusions:The survival outcomes of local resection in elderly patients with advanced ovarian cancer are not inferior to those of cytoreductive surgery. For FIGO stage Ⅳ patients, the survival period following local resection is superior to that of cytoreductive surgery.

Objective To compare the safety and efficacy of flow diverter with adjunctive spring coils(FAC)and simple flow diverter(FD)in the treatment of large or giant intracranial aneurysms.Methods The clinical data of 48 patients with large or giant intracranial aneurysm(55 intracranial aneurysms in total),who were treated at the First Affiliated Hospital of Zhengzhou University of China from January 2018 to September 2023,were retrospectively analyzed.According to the treatment method,the patients were divided into pure FD group and FAC group.The aneurysm occlusion rate and the incidence of procedure-related complications were compared between the two groups.Univariate and multivariate logistic regression analyses were used to identify risk factors for procedure-related complications.Results A total of 55 intracranial aneurysms detected in the 48 patients were included in this study.The median maximum diameter of aneurysms was 20.25 mm(16.45,24.62 mm).Among them,12 aneurysms were treated with FD alone,and 43 aneurysms were treated with FAC.The median follow-up time was 6.63 months(5.88,8.07 months).Compared with pure FD group,in FAC group the occlusion rate of aneurysms was significantly higher(86.1％vs.50.0％,P=0.023),while there was no statistically significant difference in the incidence of procedure-related complications between the two groups(18.18％vs.16.67％,P=1.000).Multivariate logistic regression analysis showed that the use of more than one stent(OR=6.63,95％CI=1.10-39.88,P=0.039)and the difference between the distal parent artery diameter and the stent diameter(Dd)(OR=7.00,95％CI=1.4-35.7,P=0.019)were the independent risk factors for procedure-related complications.The area under the receiver operating characteristic curve(AUC)of the receiver operating characteristic curve(ROC)for distal parent artery Dd was 0.854(95％CI=0.746-0.963).Conclusion For the treatment of large or giant intracranial aneurysms,FAC is clinically safe and effective.The mid-term follow-up aneurysm occlusion rate of FAC is higher than that of simple FD treatment.The use of more than one stent and the distal parent artery Dd are the independent risk factors for procedure-related complications in the treatment of large or giant intracranial aneurysms with FD.

Objective:To evaluated the efficacy and safety of eltrombopag in patients with systemic lupus erythematosus (SLE)-related refractory immune thrombocytopenia (ITP).Methods:Nine patients with severe SLE-associated refractory ITP were recruited the People's Hospital of Xinjiang Uygur Automomous Region from Septermber 2021 to February 2024 and received eltrombopag 50 mg orally daily for 1 month; basic patient information, platelet counts, other laboratory parameters and adverse events were recorded. Normally distributed continuous data were expressed as mean±standard deviation ( Mean±SD) and compared using paried samples t-test; non-normally distributed data were presented as median (interquartile range) [ M( Q1, Q3)]; categorical variables were described as n (%). Results:Eight participants (88.9%) completed the study, and at 1 month, five patients showed significant improvement in subcutaneous bleeding and erythema of the skin and mucous membranes, and three patients showed significant relief of joint and muscle involvement, and the patients′ platelet counts were (16.9±9.6)×10 9/L before treatment and increased to (114.0±53.9)×10 9/L. Differences in platelet levels before and after treatment in intergroup comparisons ( t=-4.881 , P=0.002), of which 4 patients achieved complete remission of platelet involvement, 3 patients achieved partial remission of platelet involvement, 4 cases were significantly efficacious and 3 cases efficacious. Follow-up data showed that platelet counts remained normal with no significant adverse events and one patient discontinued the study after 2 weeks of eltrombopag due to abnormal blood counts. Conclusion:Eltrombopag may be a promising new option for patients with SLE-associated refractory ITP with satisfactory remission rates, but large sample studies are needed for validation.

[Objective] To investigate the functional differences and potential effects of chromatin spatial structure in patients with normal karyotype and complex karyotype multiple myeloma. [Methods] High-throughput chromosome conformational capture (Hi-C) analysis was performed on plasma cells of 1 case with 1q21 complex karyotype and 1 case with normal karyotype multiple myeloma, and the differences in three-dimensional genome structure between the two patients were analyzed, and the transcriptome characteristics of plasma cells were combined to investigate the differential features through gene functional enrichment. [Results] A/B switch occurred in 36% of the chromatin compartments in two cases, and 1 041 genes in patient with complex karyotype had B/A switch. About 3 500 topological association domains (TADs) were identified in each sample, and there was no significant difference. The number of loops identified in complex karyotype sample was 1 069, which was 1/6 of the normal sample, and there were significant differences in the number of three different types of loops, which to some extent reflected the loss of genome stability. Transcriptome analysis showed significant differences in expression profiles between the two patients, and a total of 6 150 differentially expressed genes (3 303 up-regulated genes and 2 847 down-regulated genes) were identified. [Conclusion] Compared with patient with normal karyotype, patient with 1q21 complex karyotype multiple myeloma exhibit significant changes in the spatial structure of plasma cell chromatin at different levels, which leads to changes in gene expression and activation of pathways related to cancer progression.

Objective We aimed to investigate the effects of Biejiajian Pills on MHCC-97H hepatoma cells and whether Biejiajian Pills regulate the epidermal growth factor receptor (EGFR)/mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) signaling pathway through miR-885-5p.Methods SPF SD rats (n = 10) were randomly divided into the blank group and the Biejiajian Pills (1.1 g/kg) group to prepare blank and Biejiajian Pills-containing serum. MHCC-97H cells in the logarithmic growth phase were divided into the model group, blank serum groups with different concentrations (5％, 10％, 15％, and 20％), the serum containing Biejiajian Pills group, and the blank group without cells. Cell proliferation was detected by the CCK-8 assay, and the optimal intervention time and concentration of drug-containing serum were screened. MHCC-97H cells were divided into the blank control group (no intervention), the Biejiajian Pills-containing serum group (20％ Biejiajian Pills-containing serum), the miR-885-5p mimics group (transfected with miR-885-5p mimics), the miR-NC group (transfected with miR-885-5p NC), and the Biejiajian Pills-containing serum + miR-885-5p mimics group (treated with 20％ Biejiajian Pills-containing serum and transfected with miR-885-5p mimics). Cells in each group were cultured for 72 hours. A dual luciferase reporter assay was conducted to verify the targeting relationship between miR-885-5p and EGFR. Cell proliferation was detected by the CCK-8 assay, cell migration and invasion abilities were detected by the cell scratch assay and the Transwell invasion assay. Annexin V-APC/PI double staining was performed to detect the apoptosis level, and real-time fluorescence quantitative PCR (RT-qPCR) analysis was conducted to determine the mRNA expression levels of miR-885-5p, EGFR, MEK, and ERK1/2. The expression levels of EGFR, p-EGFR, MEK, p-MEK, ERK1/2, p-ERK1/2, matrix metalloproteinase 1 (MMP1), and CyclinD1 were determined by Western blotting analysis. The subcutaneous tumor model of MHCC-97H hepatoma cells in nude mice was established by subcutaneous injection to observe the inhibitory effect of Biejiajian Pills of different doses(0.55,1.1,2.2 g/kg).Results The optimal concentration and intervention time of Biejiajian Pills-containing serum were 20％ and 72 hours, respectively. Meanwhile, the dual luciferase reporter assay showed that miR-885-5p could directly target EGFR. No statistical significances between the blank control group and the miR-NC group were observed (P>0.05). Compared with the blank control group, the proliferation rates of MHCC-97H hepatoma cells in the Biejiajian Pills-containing serum group, the miR-885-5p mimics group, and the Biejiajian Pills-containing serum + miR-885-5p mimics group were significantly decreased (P<0.01), and their migration and invasion abilities were significantly decreased (P<0.05, P<0.01). At the same time, the protein expression levels of CyclinD1 and MMP1, which are closely related to cell proliferation and invasion, were significantly downregulated (P<0.05, P<0.01). The proportions of late apoptotic cells and the proportion of total apoptotic cells were significantly increased (P<0.01). In the Biejiajian Pills-containing serum group, the miR-885-5p mimics group, and the Biejiajian Pills-containing serum + miR-885-5p mimics group, miR-885-5p mRNA was significantly upregulated (P<0.01) and EGFR, MEK, and ERK1/2 were significantly downregulated at the mRNA level (P<0.05, P<0.01). EGFR, MEK, and ERK1/2 phosphorylation was inhibited (P<0.01), and the Biejiajian Pills-containing serum + miR-885-5p mimics group showed the best effect (P<0.05, P<0.01). The subcutaneous liver tumor model in nude mice verified that Biejiajian Pills can inhibit tumor growth in a dose-dependent manner. Conclusion Biejiajian Pills can promote apoptosis of MHCC-97H hepatoma cells and inhibit their proliferation, invasion, and migration. The mechanism may be related to the targeted regulation of the EGFR/MAPK/ERK signaling pathway by miR-885-5p.

Objective To analyze the risk factors for extrauterine growth retardation(EUGR)in late preterm infants appropriate for gestational age.Methods The clinical data in 1 402 preterm infants appropri-ate for gestational age delivered and hospitalized in this hospital from January 2016 to June 2022 were analyzed retrospectively.They were divided into the EUGR group(n=244)and the non-EUGR group(n=1 158)ac-cording to whether or not the body weight at discharge was below the 10th percentile of the growth curve for the same gestational age at the same period based on the Fenton's preterm growth curve.The clinical data of preterm infants and mothers of the two groups were collected.The risk factors for EUGR occurrence in pre-mature infants were analyzed.Results Among 1 402 preterm infants appropriate for gestational age,EUGR occurred in 244 cases with the EUGR incidence rate of 17.4％.The EUGR incidence rate had no statistical difference among the different fetal ages of premature infants(P＞0.05).The EUGR incidence rate had sta-tistical difference among different birth weights of premature infants(P＜0.05).The logistic regression anal-ysis showed that male(OR=1.694,95％CI:1.144-2.507),low birth weight(OR=0.989,95％CI:0.988-0.991),feeding intolerance(OR=2.719,95％CI:1.234-5.990),short gestational weeks(OR=0.146,95％CI:0.103-0.207)and hospitalization duration extension(OR=1.073,95％CI:1.031-1.117)were the risk factors for EUGR occurrence in late premature infants appropriate for gestational age in discharge.The sub-group analysis showed that male,low birth weight,feeding intolerance and hospitalization duration extension were the risk factors for EUGR occurrence in the preterm infants with gestational ages of 34-＜36 weeks(P＜0.05).Low birth weight and feeding intolerance only affected the preterm infants≥36 weeks of gesta-tional age(P＜0.05).Conclusion Strengthening the pregnant duration health care and active nutritional sup-port after birth may reduce the risk of EUGR occurrence in late premature infants.
