Aim To investigate the effects of Ginkgo biloba extract(GBE)on vascular endothelial dysfunc-tion induced by chronic intermittent hypoxia(CIH)in rats and its related mechanisms.Methods The CIH rat model was established,and 50 and 100 mg·kg-1 GBE was administered by intragastric administration.The systolic blood pressure(SBP)of the tail artery was detected in each group.HE staining was used to detect the morphology of aorta tissue.DAF-FM DA staining and nitric reductase assay were used to detect NO levels.ELISA was used to detect serum ET-1,TNF-α and IL-6 levels.DHE staining was used to de-tect reactive oxygen species(ROS)levels of aortic tis-sue.Kits were used to detect the serum levels of MDA,SOD and GSH-Px.Western blot was used to detect the levels of VCAM-1,ICAM-1,nucleus Nrf2,HO-1 and NQO1 of aortic tissue.Results GBE sig-nificantly decreased the levels of SBP,ET-1,ROS,MDA,VCAM-1,ICAM-1,TNF-α and IL-6,and sig-nificantly increased the levels of NO,SOD,GSH-Px,nuclear Nrf2,HO-1 and NQO1 in CIH rats.GBE sig-nificantly improved the histomorphology of aorta in CIH rats.Conclusions GBE can improve vascular endo-thelial dysfunction and reduce blood pressure in CIH model rats.The mechanism may be related to the acti-vation of Nrf2/ARE pathway and the inhibition of oxi-dative stress and inflammation by GBE.

Objective: To identify the maximum tolerated dose (MTD) of docetaxel combined with a fixed dose of cisplatin (75 mg/m 2 ) delivered as hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with ovarian cancer. Methods: In this phase I trial, a time-to-event Bayesian optimal interval design was used.Docetaxel was given at a starting dose of 60 mg/m2 and was increased in 5 mg/m2 increments until the MTD was determined or the maximum dose level of 75 mg/m2 was reached. The doselimiting toxicity (DLT) rate was set at 25%, with a total sample size of 30 patients. HIPEC was delivered immediately following debulking surgery at a target temperature of 43°C for 90 minutes. Results: From August 2022 to November 2022, 30 patients were enrolled. Among the patients who received a dose of docetaxel ≤65 mg/m2 , no DLT was reported. DLTs were observed in one patient who received 70 mg/m2 docetaxel (grade 3 anaemia) and in three patients who received 75 mg/m2 docetaxel (one case of grade 3 anaemia, one case of grade 3 hepatic impairment and one case of grade 4 thrombocytopenia). Patients treated with docetaxel 75 mg/m2 in combination with cisplatin 75 mg/m2 had an estimated DLT rate of 25%, which was the closest to the target DLT rate and was therefore chosen as the MTD. Conclusion Docetaxel, in combination with a fixed dose of cisplatin (75 mg/m2), can be used safely at intraperitoneal doses of 75 mg/m2 in ovarian cancer patients who received HIPEC (43°C, 90 minutes) following debulking surgery.

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

ObjectiveTo identify potential distribution areas for wild Panax ginseng cultivated under forest in Liaoning province， China， and analyze the ecological factors of spatial stratified heterogeneity affecting its ecological suitability and quality suitability. MethodWild Panax ginseng samples cultivated under forest were collected from 33 cultivation bases in Liaoning province. The Maxent maximum entropy model and ArcGIS were used to delineate the ecological suitability zones. Correlation analysis was performed on seven indicators and 110 ecological factors. Variables with significant correlation （P<0.05） were used to build partial least squares regression analysis models. A comprehensive quality zoning was conducted using the analytic hierarchy process （AHP）. The geographic detector was employed to analyze the interactions among dominant ecological factors of spatial stratified heterogeneity affecting habitat suitability， quality suitability， and the ecological driving factors. ResultVegetation type was the most influential ecological factor for delineating the ecological suitability zones for wild Panax ginseng in Liaoning province. The main ecological suitability areas for wild Panax ginseng cultivated under forest were located in the northeast， east， and southeast regions along the line from Xifeng County to Gaizhou City. The comprehensive quality suitability of wild Panax ginseng cultivated under forest was highest in Kuandian County and Huanren County and gradually decreased to the northwest and southwest. Within the delineated regions， the suitability conditions and comprehensive quality of wild Panax ginseng cultivated under forest were primarily influenced by the interactions between radiation and precipitation factors. The content of the measured samples was significantly higher than the standards in the 2020 edition of the Chinese Pharmacopoeia， indicating the high overall quality of wild Panax ginseng in Liaoning Province. ConclusionAccording to the zoning and prediction results， areas in Fengcheng City， Xiuyan County， Zhuanghe City， Liaoyang County， Tieling County， Xifeng County， Gaizhou City， Haicheng City， and Dashiqiao City showed large potential distribution areas with high quality， making them highly promising for wild Panax ginseng cultivation. However， further experimental verification is required. The zoning results can provide insights for research on habitat suitability and comprehensive quality accumulation of wild Panax ginseng cultivated under forest， as well as guidance for the search for potential cultivation areas and industrial development of wild Panax ginseng in Liaoning Province.

OBJECTIVE: To examine the anti-inflammatory effect of grape seed extract (GSE) in animal and cellular models and explore its mechanism of action. METHODS: This study determined the inhibitory effect of GSE on macrophage inflammation and Th1 and Th17 polarization in vitro. Based on the in vitro results, the effects and mechanisms of GSE on multiple sclerosis (MS)-experimental autoimmune encephalomyelitis (EAE) mice model were further explored. The C57BL/6 mice were intragastrically administered with 50 mg/kg of GSE once a day from the 3rd day to the 27th day after immunization. The activation of microglia, the polarization of Th1 and Th17 and the inflammatory factors such as tumor necrosis factor- α (TNF- α), interleukin-1 β (IL-1 β), IL-6, IL-12, IL-17 and interferon-γ (IFN-γ) secreted by them were detected in vitro and in vivo by flow cytometry, enzyme linked immunosorbent assay (ELISA), immunofluorescence staining and Western blot, respectively. RESULTS: GSE reduced the secretion of TNF-α, IL-1 β and IL-6 in bone marrow-derived macrophages stimulated by lipopolysaccharide (P<0.01), inhibited the secretion of TNF-α, IL-1 β, IL-6, IL-12, IL-17 and IFN-γ in spleen cells of EAE mice immunized for 9 days (P<0.05 or P<0.01), and reduced the differentiation of Th1 and Th17 mediated by CD3 and CD28 factors (P<0.01). GSE significantly improved the clinical symptoms of EAE mice, and inhibited spinal cord demyelination and inflammatory cell infiltration. Peripherally, GSE downregulated the expression of toll-like-receptor 4 (TLR4) and Rho-associated kinase (ROCKII, P<0.05 or P<0.01), and inhibited the secretion of inflammatory factors (P<0.01 or P<0.05). In the central nervous system, GSE inhibited the infiltration of CD45⁺CD11b⁺ and CD45⁺CD4⁺ cells, and weakened the differentiation of Th1 and Th17 (P<0.05). Moreover, it reduced the secretion of inflammatory factors (P<0.01), and prevented the activation of microglia (P<0.05). CONCLUSION GSE had a beneficial effect on the pathogenesis and progression of EAE by inhibiting inflammatory response as a potential drug and strategy for the treatment of MS.
