Liver cancer is a prevalent and highly malignant cancer worldwide,with 90％of cases being hepatocellular carcinoma,presenting a significant risk to human health.As early-stage liver cancer often lacks specific manifestations,most patients with liver cancer are already in the middle and late stage of the disease when liver cancer is diagnosed,thus,missing the opportunity for optimal radical treatment.However,the exploration of the treatment for middle and advanced primary hepatocellular carcinoma has never ceased.In recent years,transarterial chemoembolization(TACE)has been included in the standard treatment regimens for primary hepatocellular carcinoma.With the advancement of multidisciplinary comprehensive treatment,various treatment options to reduce the burden of liver cancer lesion with satisfactory therapeutic results have been reported and have been widely used in clinical practice,e.g.hepatic artery infusion chemotherapy(HAIC),targeted therapy,and immunotherapy in combination with TACE,which have significantly improved the overall survival of patients with liver cancer.This paper aims to make a comprehensive review about the latest progress of combination use of TACE and other therapies in reducing tumor burden and improving patient survival in the treatment of primary hepatocellular carcinoma,and to summarize the key issues in combination therapy that require more in-depth research.(J Intervent Radiol,2024,33:688-692)

Purpose: The aim of this study was to compare the effectiveness and outcomes of percutaneous ablation guided by ultrasonography (US) and computed tomography (CT) in colorectal liver oligometastases (CLOM). Methods: This study included patients with CLOM treated with percutaneous ablation from January 2008 to January 2021 in this observational study. Only lesions visualized on both CT and US images were further analyzed according to whether patients’ initial ablation treatments utilized US guidance or CT guidance. The Kaplan-Meier method was used to estimate local tumor progression (LTP)–free survival after propensity score matching (PSM). The LTP-free survival and treatment-related outcomes were compared between these two groups. Results: PSM identified 116 patients from each group, with 269 and 238 lesions in the USguided and CT-guided groups, respectively. US-guided ablation had a shorter average procedure time and lower cost than CT-guided ablation (27.54±12.06 minutes vs. 32.70±13.88 minutes, P=0.003; $2,175.13±618.17 vs. $2,455.49±710.25, P=0.002). For patients >60 years of age, the cumulative LTP rate at 1 year was lower in the US-guided group than in the CT-guided group (17.8% vs. 25.1%, P=0.038). For patients with perivascular liver lesions, the cumulative LTP rate at 1 year was lower in the US-guided group (14.4% vs. 28.2%, P=0.040). Conclusion For patients whose age is >60 years or who have perivascular liver lesions, USguided ablation is better than CT-guided ablation, with a shorter treatment time and lower costs when both ablation methods are feasible for patients.

Acute myeloid leukaemia (AML) is the most common form of acute leukaemia in adults, with increasing incidence with age and a generally poor prognosis. Almost 20% of AML patients express mutant isocitrate dehydrogenase 2 (mIDH2), which leads to the accumulation of the carcinogenic metabolite 2-hydroxyglutarate (2-HG), resulting in poor prognosis. Thus, global institutions have been working to develop mIDH2 inhibitors. SH1573 is a novel mIDH2 inhibitor that we independently designed and synthesised. We have conducted a comprehensive study on its pharmacodynamics, pharmacokinetics and safety. First, SH1573 exhibited a strong selective inhibition of mIDH2 R140Q protein, which could effectively reduce the production of 2-HG in cell lines, serum and tumors of an animal model. It could also promote the differentiation of mutant AML cell lines and granulocytes in PDX models. Then, it was confirmed that SH1573 possessed characteristics of high bioavailability, good metabolic stability and wide tissue distribution. Finally, toxicological data showed that SH1573 had no effects on the respiratory system, cardiovascular system and nervous system, and was genetically safe. This research successfully promoted the approval of SH1573 for clinical trials (CTR20200247). All experiments demonstrated that, as a potential drug against mIDH2 R140Q acute myeloid leukaemia, SH1573 was effective and safe.

Tumor microenvironment has been widely utilized for advanced drug delivery in recent years, among which hypoxia-responsive drug delivery systems have become the research hotspot. Although hypoxia-responsive micelles or polymersomes have been successfully developed, a type of hypoxia-degradable nanogel has rarely been reported and the advantages of hypoxia-degradable nanogel over other kinds of degradable nanogels in tumor drug delivery remain unclear. Herein, we reported the synthesis of a novel hypoxia-responsive crosslinker and the fabrication of a hypoxia-degradable zwitterionic poly(phosphorylcholine)-based (

Objective To explo the antioxidant effect and molecular mechanism of gastrodin (Gas) in epilepsy (EP) rats induced by LiCl-pilocarpine (PILO) . Methods Eighty male SD rats were randomly divided into 5 groups: sham group, EP group, therapy groups (pretreated with 60 mg/kg, 90 mg/kg, 120 mg/kg of gastrodin respectively) . The EP model was esteblished by peritoneal injection of LiCl-PILO. Therapy groups were pretreated with various concerntration of Gas. The control group was given the same dosage of normal saline. The alteration of behavior was observed, the concentration of catalase (CAT), glutathion (GSH), superoxide dismutase (SOD), glutathion reductase (GR), total antioxidtion (T-AOC) and malondialdehyde (MDA) in rats brain cortex were detected by chemical colorimetric method, phosphorylation of p38 was determined by western blot. Results There was no EP seizure in sham group,and the EP seizure degree in therapy groups (gas pretreated groups) was significantly decreased,and had statistically significant difference with EP group (P<0.05) . The EP model rats exhibited a significant decrease in the concentration of endogenous antioxidants (CAT, GSH, SOD, GR and T-AOC), while an increase of the concentration of MDA and phosphorylation p38 protein as compared to sham group (P<0.05) . After treatment of the Gas,treatment group rats attenuated the seizure degree,exhibited a significant increase of the concentration of endogenous antioxidants (P<0.05),while a decrease in concentration of MDA and phosphorylation of p38 as compared to model group (P<0.05) . Conclusion Gas may have a neuroprotective role in central nervous system of epileptic rats modle by down-regulateing the seizure degree and the activity of p38 kinase and up-regulateing the content of endogenous antioxidants.

Objective To establish a method focusing on regulation of CNN3 gene in the rat hippocampus and help to explore the role of CNN3 gene played in the brain physiology and pathology.Methods One cDNA sequence and three shRNAs targeting CNN3 gene were designed and synthesized.The recombinant lentivirus-mediated expressing and three short hairpin RNA ( shRNA) vectors targeting CNN3 gene in the rats were constructed with engineering technology.All recombinant vectors were intravenously injected into rats hippocampi guided by stereotaxic apparatus.Western blot was performed to explore the best shRNA and to study the changes of CNN3 gene in the rat hippocampus after transfection with the silence and over-expressed vectors.Results The lentivirus-mediated vector expressing CNN3-OE and three shRNA vectors targeting CNN3 gene were successfully constructed.Within eight weeks after transfection, the vectors of CNN3-OE and three CNN3-shRNAs changed the expression of CNN3 gene in the rat hippocampus, in particular, all the protein levels of calponin-3 encoded by CNN3 gene were significantly down-regulated along with the time, with the highest inhibitory rate of 73.6%in the CNN3-shRNA2 group.Significant up-regulation of calponin-3 protein level by 93.88%, was found only on the 14th day after transfection.Conclusions Lentivirus-mediated vectors of CNN3-OE and CNN3-shRNAs may regulate in vivo the CNN3 gene level in the local brain region of rats via stereotactic injection.The study lays a foundation for disease prevention and treatment in the future.

Objective To explore the activition and polarization of microglia in the epileptic rats induced by lithium chloride-pilocarpine. Methods One hundred male SD rats were randomly divided into five groups: control group and different time points model groups including 1d,3d,7d and 14d. Epilepsy models were established by lithium chloride-pilocarpine intraperitoneal injection. The control group was given the same dosage of normal saline. The morphology change was detected by immunofluorescence,and the expressions of iNOS and Arg-1 were determined by IHC at respective time points. Results Compared the model groups with control group,microglia was activated,synapsis was shorten,volume got bigger,most of them seemed as amoebocyte,the expression of iNOS increased and Arg-1 decreased,especially at 3d.ConclusionThe results from this study indicated that microglia was activated and polarized in epileptic rats induced by pilocarpine.

Objective To investigate severe complications of inferior vena cava filter (IVCF) applying for preventing pulmonary embo-lism after spinal cord injury. Methods From December 2014 to July 2015, 95 patients with acute spinal cord injury (SCI) in our hospital were retrospected. Results Deep venous thrombosis (DVT) appeared in 23 cases, in which 15 cases placed IVCF. All patients accepted anti-coagulant therapy, except 10 cases with contraindication. 3 cases had severe complication, in which 2 cases had comprehensive DVT distal to IVCF, with both lower limbs severe swelling, acute renal inadequacy and hypertension;1 case had continuous hyperpyrexia. Conclusion Although the IVCF placement was widely used in acute SCI for preventing pulmonary embolism in patients with DVT, however, the selec-tion of IVCF and complication prevention should be taken into account.
