This study aimed to evaluate the efficacy and safety of combining albumin-bound paclitaxel (abpaclitaxel) and anlotinib for ovarian cancer. In this study, 44 patients diagnosed with platinum-resistant ovarian cancer were enrolled. Patients received ab-paclitaxel along with anlotinib until disease progression or intolerable toxicity. Efficacy was assessed according to RECIST 1.1 criteria or Rustin's criteria. The primary endpoint was the investigator-evaluated objective response rate (ORR). 44 patients were enrolled between January 2021 and March 2023 with a median age of 49 years. Twenty-nine had measurable lesions and 15 had non-measurable lesions. Overall, the investigator-evaluated ORR was 56.8% (25/44; 95% CI 0.411-0.713) in intention-to-treat population and 58.1% (25/43; 95% CI 0.422-0.726) in per-protocol population. The median progression-free survival was 9.8 months, and the median duration of response was 7.4 months. For safety, grade 3/4 adverse events (AEs) included leukopenia, gum pain, hypertension, and hand-foot syndrome. The response rates were 55.0% (11/20) in patients with previous use of antiangiogenic reagents and who had previous use of PARP inhibitors. The combination of ab-paclitaxel and anlotinib showed promising anti-tumor activity and a manageable safety profile in platinum-resistant ovarian cancer. Patients with previous use of antiangiogenic drugs or PARP inhibitors still benefited from this protocol.

Objective To investigate the effects of anti-HLA donor-specific antibodies(DSA)and desensitization for DSA+patients on engraftment of haploidentical hematopoietic stem cell transplantation(haplo-HSCT).Methods The patients who underwent haplo-HSCT and examinations for HLA antibodies and DSA in our department from March 2017 to July 2023 were recruited in this study.The effects of desensitization measure on engraftment in the DSA+patients after haplo-HSCT were analyzed.Results Among the 70 patients who underwent haplo-HSCT and test for HLA antibodies,15(21.4％)patients were DSA positive,including 7(46.7％)cases of strong positive,3(20.0％)cases of moderate positive,and 5(33.3％)cases of weak positive.The median duration for neutrophil implantation was significantly extended in the DSA+patients than the negative patients(P=0.027).For the 6 patients developed graft failure(GF),4 were DSA+which was statistically higher than the DSA-patients(P=0.025).Multivariate regression analysis showed that DSA was an independent factor affecting GF(HR=9.273,95％CI:1.505～57.124,P=0.016).Among the 10 patients(7 strong positive and 3 moderate positive DSA)received desensitization therapy,4 patients received combination desensitization,with a 100％rate of successful transplantation,and 6 received single desensitization,with 4(66.7％)experiencing GF,so the GF rate was obviously lower in the combination than the single desensitization(P=0.008).Conclusion In haplo-HSCT patients,DSA is an important factor leading to implantation delay and GF.While,single desensitization treatment has limited efficacy.In combined DSA desensitization therapy,the decrease of antibody titer should be dynamically monitored to ensure the successful implantation of stem cells and reduce GF rate.

Objective To observe the value of nomogram based on enhanced cortical phase CT Radscore combined with CT features for predicting synchronous distant metastasis(SDM)of renal cell carcinoma(RCC).Methods Totally 139 RCC patients from center A were retrospectively enrolled and divided into SDM group(n=46)and non-SDM group(n=93),also classified as training set(n=97)and test set(n=42)at a ratio of 7∶3.Additionally,20 RCC patients from center B were included as validation set(8 cases with SDM and 12 cases without SDM).Radiomics features were extracted and screened based on enhanced cortical phase CT images to calculate Radscore.Multivariate logistic regression analysis was performed to identify independent predictors of RCC SDM among clinical and CT features.Then a logistic regression model was constructed combining Radscore and independent predictors of RCC SDM and visualized as a nomogram.The receiver operating characteristic curve and the area under the curve(AUC)was used to assess the efficacy of the nomogram for predicting RCC SDM.Results The maximum tumor diameter,CT-T stage and perirenal adipose stranding were all independent predictors of RCC SDM(all P＜0.01).Radscore was calculated based on 5 optimal features.The nomogram was constructed based on perirenal adipose stranding,CT-T stage and Radscore.AUC of the model for predicting RCC SDM in training set,test set and validation set was 0.964,0.921 and 0.885,respectively.Conclusion Enhanced cortical phase CT Radscore combined with perirenal adipose stranding and CT-T stage could effectively predict RCC SDM.

Objective To explore the relationship between non-high density lipoprotein cholesterol(non-HDL-C)level and leptomeningeal collateral circulation in patients with acute middle cerebral artery occlusion.Methods A total of 85 patients with first-onset acute cerebral infarction with middle cerebral artery M1 segment occlusion were enrolled.According to the results of DSA,LMC circulation was assessed by American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology Collateral Circulation Assess-ment System.All patients were assigned to better LMC circulation group(score 2～4,n = 30)and worse LMC circulation group(score 0～1,n = 55),and the levels of non-HDL-C were compared between the two groups.Results The levels of LDL-C and non-HDL-C in worse LMC circulation group were significantly higher than those of the better LMC circulation group(P = 0.026,P = 0.010).non-HDL-C was an independent risk factor for the worse LMC circulation(OR = 3.019,95%CI:1.053～8.658,P = 0.04).LMC circulatory score of patients was negatively correlated with the levels of non-HDL-C level(r =-0.228,P = 0.036).The AUC of non-HDL-C predicted for the worse LMC circulation was 0.638(95%CI:0.521～0.755,P = 0.036).Conclusions non-HDL-C in patients with acute cerebral infarction was significantly related to worse LMC circulation,and was a risk factor for worse LMC circulation.It is suggested that the higher expression of non-HDL-C could be used to predict worse LMC circulation as a serological indicator.

Objective:To explore the correlation between dietary fiber intake and intestinal barrier function in patients with irritable bowel syndrome with diarrhea (IBS-D).Methods:IBS-D patients were recruited from May 2019 to October 2019 at the clinic of gastroenterology department in China-Japan Friendship Hospital and healthy controls (HCs) were recruited by advertisement. Clinical manifestations, psychological status and quality of life were assessed using standardized questionnaires. A food frequency questionnaire was used to assess dietary habits in the preceding year. Serum diamine oxidase (DAO) was measured via ELISA.Results:64 IBS-D patients and 35 HCs were enrolled, with no significant difference in sex ratio, age and BMI between the two groups. Second to health concern, food avoidance was the dominant impacting factor for quality of life in IBS-D patients. The intake frequency of dietary fiber was decreased in IBS-D patients, and the intake frequencies of dietary fiber-rich foods were significantly lower in IBS-D patients ( P < 0.01 for tubers, P = 0.002 for vegetables, P = 0.019 for fruits and P = 0.045 for legumes). On the other hand, the intake frequencies of processed meat ( P < 0.01), greasy food ( P = 0.009), barbecued food ( P = 0.002) and animal offal ( P = 0.003) were significantly higher in IBS-D patients compared with HCs, indicating the increased intake frequency of fat. Multivariate logistic regression showed that tubers might reduce the risk of IBS-D ( OR = 0.409,95% CI: 0.232 to 0.722, P = 0.002). The frequency of abdominal pain was positively associated with the intake frequency of greasy food in IBS-D patients. Serum DAO was measured in 37 IBS-D patients and 27 HCs. IBS-D patients had significantly higher serum DAO than HCs ( 77.0 [55.3, 100.6] μg/L vs 42.5 [28.0, 58.2] μg/L, P < 0.01). Among all the participants with serum DAO test results, the level of DAO was negatively associated with the intake frequencies of tubers, vegetables and fruits while positively associated with the intake frequencies of processed meat and barbecued food. Conclusions:Food avoidance was an important impacting factor for quality of life in IBS-D patients. IBS-D patients might have insufficient dietary fiber intake and excessive fat intake. Tubers could possibly reduce the risk of IBS-D. The decreased intake frequency of dietary fiber might have a role in intestinal barrier dysfunction in IBS-D patients.
