Objective:To investigate the diagnosis, treatment, clinical characteristics and potential high-risk factors of cerebral venous sinus thrombosis (CVST) during the treatment of acute lymphoblastic leukemia (ALL) with pegaspargase.Methods:The medical history, diagnosis and treatment process, laboratory examination and imaging examination results of 3 ALL patients with CVST during pegaspargase treatment in the First Affiliated Hospital of Suzhou University in March and November 2021 and September 2022 were retrospectively analyzed, and the relevant literature was reviewed.Results:Three patients were all female, with the aged between 15 and 35 years old, including 2 cases of B-ALL and 1 case of T-ALL. All patients developed nervous system symptoms after pegaspargase chemotherapy, and were diagnosed as CVST by imaging examination. During the pegaspargase treatment, 2 patients took norethisterone, and 1 patient underwent induced labor and curettage. The levels of sexual hormones in the 3 patients had non-physiological changes. The main CVST lesions were located in the superior sagittal sinus, transverse sinus and sigmoid sinus. One patient had cerebral hemorrhage at the same time. When thrombus occurred, the fibrinogen (Fib), antithrombin Ⅲ (AT Ⅲ) activity, protein C activity and protein S activity of the patients were significantly lower than those before, D-dimer was significantly higher, and lupus anticoagulant and anticardiolipin antibody were negative. The thrombosis treatment was mainly anticoagulation, and 1 patient underwent thrombolysis. Two patients had no sequelae of nervous system, and 1 patient had the sequelae of muscle weakness.Conclusions:Patients with ALL should be alert to the occurrence of CVST when they have nervous system symptoms during pegaspargase chemotherapy. The diagnosis of CVST mainly depends on cranial imaging. Anticoagulation is the main thrombosis treatment, thrombolysis and interventional thrombectomy are feasible for some patients, with few neurological sequelae. The use of second-generation progesterone drugs and the non-physiological fluctuation of sex hormones may be the potential risk factors of CVST.

BACKGROUNDAnticoagulation treatments are an important aspect of hemodialysis; however, few reports have addressed these treatments. This investigation intends to increase the understanding of the current status and improvements of hemodialysis-related anticoagulation treatments in China.
METHODSIn this study, an epidemiological investigation was conducted that examined 842 patients in 2007 and 1 175 patients in 2012 who underwent hemodialysis anticoagulation treatments in seven blood purification centers in northern Chinese cities.
RESULTSHeparin was the most commonly used anticoagulant, although the percentage of use of low-molecular-weight heparin (LMWH) increased from 26.5% in 2007 to 42.1% in 2012. In 2007, there were no significant differences in anticoagulant selection among either patients with various primary diseases or patients with hemorrhage, thrombosis, thrombocytopenia, or a low hemoglobin level. However, compared with patients with other diseases, significantly lower doses of LMWH were administered to patients with hypertension (55.5 U/kg vs. 67.3 U/kg, P < 0.05) or diabetes (58.5 U/kg vs. 67.3 U/kg, P < 0.05), and patients with hemorrhage received lower doses of heparin than the other patients (61.6 U/kg vs. 71.8 U/kg, P < 0.01). In 2012, patients with diabetic nephropathy (51.5% vs. 36.5%, P < 0.01), hemorrhage (43.4% vs. 31.7%, P < 0.01), or a hemoglobin level below 90 g/L (57.2% vs. 37.1%, P < 0.01) experienced significantly higher doses of LMWH administration; patients with hemorrhage received significantly reduced LMWH dosages (50.4 U/kg vs. 57.8 U/kg, P < 0.05), and patients with thrombosis received significantly higher doses of heparin (73.8 U/kg vs. 62.1 U/kg, P < 0.01) or LMWH (57.8 U/kg vs. 52.6 U/kg, P < 0.05). Antiplatelet drugs were administered to 20.4% of the examined patients in 2007 and 20.7% in 2012. In 2012, patients with hypertension (25.9% vs. 18.5%, P < 0.01) and thrombosis (36.6% vs. 16.1%, P < 0.01) had a higher rate of using antiplatelet drugs than patients with other primary diseases and complications. Patients receiving antiplatelet drugs also received higher doses of heparin than patients without using antiplatelet drugs (74.4 U/kg vs. 65.9 U/kg, P < 0.01). However, the use of the drugs was not correlated with thrombocytopenia. The rate at which coagulation indices were determined increased from 45.7% in 2007 to 64% in 2012.
CONCLUSIONThese findings suggested that hemodialysisrelated anticoagulation treatments in China have gradually become more standardized and individualized.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).
