Cerebral venous sinus thrombosis （CVST） is a rare cerebrovascular disease characterized by the formation of blood clots in the intracranial venous system due to various causes， resulting in obstruction of intracranial blood flow or cerebrospinal fluid circulation disorder. This disease often has diverse clinical symptoms， including increased intracranial pressure and focal neurological deficits. Antithrombin Ⅲ （AT Ⅲ）， encoded by the SERPINC1 gene， acts as a serine protease inhibitor for thrombin and coagulation factors Ⅻα， Ⅺα， Ⅸα， and Ⅹα， and antithrombin deficiency caused by SERPINC1 gene mutations is a risk factor for thrombosis. This article reports a case of CVST due to ATⅢ deficiency caused by common mutations in both the intron and exon regions of the SERPINC1 gene in our hospital.

Parkinson's disease(PD)is the second most prevalent neurodegenerative disease and a major cause of movement disorders.Neuroinflammation plays an important role in the pathogenesis of PD.Icilin is a small molecule compound that has been reported to inhibit inflammation.Howev-er,its role in PD has not been reported.This study explored the effects of icilin on motor behavior,nerve damage,microglia activation,and neuroinflammation in MPTP-induced PD Meriones unguic-ulatus by behavioral experiments,immunohistochemistry,Western blot,and fluorescence quantifi-cation.The results showed that Icilin not only ameliorated motor dysfunction and neurological damage in MPTP-induced Meriones unguiculatus,but also inhibited microglia hyperactivation and its mediated neuroinflammation.The present study provides an evidence that icilin attenuates MPTP-induced neurodegenerative lesions in long-pawed gerbils,suggesting that it is a promising candidate for PD.

AIM:This study aims to investigate the molecular mechanism by which tubeimoside I(TBMS1)inhibits Snail expression in pancreatic cancer cells(PANC-1).METHODS:Human pancreatic cancer PANC-1 cells were cultured in vitro.The inhibitory effect of TBMS1 on PANC-1 cells was assessed using the MTT assay,and the data were analyzed based on the IC50 value of TBMS1.The impact of TBMS1 on the clonal formation ability of PANC-1 cells was evaluated through colony formation assays.The Transwell assay was employed to assess the effect of TBMS1 on the migrato-ry capability of PANC-1 cells.Apoptosis and cell cycle alterations in PANC-1 cells were analyzed using acridine orange staining and flow cytometry.The expression of Snail protein in pancreatic cancer and its relationship with survival of the patients were analyzed using the GEPIA database and Kaplan-Meier Plotter data.Immunofluorescence staining was con-ducted to investigate the effect of TBMS1 on Snail expression,while Western blot was used to evaluate the expression of poly(ADP-ribose)polymerase(PARP),E-cadherin and Snail in the cells.The ubiquitination of Snail protein was mea-sured using immunoprecipitation techniques.RESULTS:As the concentration of TBMS1 increased,the survival rate and number of clones formed by PANC-1 cells progressively decreased,leading to apoptosis,cleavage of PARP,and cell cycle arrest in the G1 phase.There was also a reduction in the proportion of cells in the S phase and a decrease in cell migration ability.The expression of Snail protein,a critical factor in cell migration,was inhibited,while E-cadherin protein levels were increased.Treatment with the proteasome inhibitor MG132 was able to reverse the suppression of Snail protein ex-pression caused by TBMS1.Immunoprecipitation results indicated that TBMS1 enhances the ubiquitination and subse-quent degradation of Snail protein.CONCLUSION:TBMS1 effectively inhibits the malignant progression of pancreatic cancer cells by promoting the ubiquitination and degradation of Snail protein in PANC-1 cells.

This paper aimed to investigate the therapeutic effect and mechanism of action of the Yiqi Fumai Formula(YQFM), a kind of traditional Chinese medicine(TCM), on mice with experimental heart failure based on the "heart-gut axis" theory. Based on the network pharmacology integrated with the group collaboration algorithm, the active ingredients were screened, a "component-target-disease" network was constructed, and the potential pathways regulated by the formula were predicted and analyzed. Next, the model of experimental heart failure was established by intraperitoneal injection of adriamycin at a single high dose(15 mg·kg~(-1)) in BALB/c mice. After intraperitoneal injection of YQFM(lyophilized) at 7.90, 15.80, and 31.55 mg·d~(-1) for 7 d, the protective effects of the formula on cardiac function were evaluated using indicators such as ultrasonic electrocardiography and myocardial injury markers. Combined with inflammatory factors in the cardiac and colorectal tissue, as well as targeted assays, the relevant indicators of potential pathways were verified. Meanwhile, 16S rDNA sequencing was performed on mouse fecal samples using the Illumina platform to detect changes in gut flora and analyze differential metabolic pathways. The results show that the administration of injectable YQFM(lyophilized) for 7 d significantly increased the left ventricular end-systolic internal diameter, fractional shortening, and ejection fraction of cardiac tissue of mice with experimental heart failure(P<0.05). Moreover, markers of myocardial injury were significantly decreased(P<0.05), indicating improved cardiac function, along with significantly suppressed inflammatory responses in cardiac and intestinal tissue(P<0.05). Additionally, the species of causative organisms was decreased, and the homeostasis of gut flora was improved, involving a modulatory effect on PI3K-Akt signaling pathway-related inflammation in cardiac and colorectal tissue. In conclusion, YQFM can affect the "heart-gut axis" immunity through the homeostasis of the gut flora, thereby exerting a therapeutic effect on heart failure. This finding provides a reference for the combination of TCM and western medicine to prevent and treat heart failure based on the "heart-gut axis" theory.

OBJECTIVE: To preliminarily investigate the effects and mechanism of action of Yishen Yangsui Formula (, YSYSF)on the recovery of neurological function in rats with degenerative cervical myelopathy. METHODS: Fifty adult SD female rats were randomly divided into control group, sham group, model group, YSYSF group and positive drug group by using randomized numerical table method. In the model group, YSYSF group and positive drug group, polyvinyl alcohol acrylamide interpenetrating network hydrogel(water-absorbent swelling material) was used to construct a rat spinal cord chronic compression model. The sham group was implanted with the water-absorbent swelling material and then removed without causing spinal cord compression. The control group, the sham group and the model group were given equal amounts of saline by gavage, the group of YSYSF was given Chinese herbal medicine soup by gavage 9.1 g·kg^-1 once a day, and the positive drug group was given tetrahexylsalicylglucoside sodium monosialate ganglioside by intraperitoneal injection 4.2 mg·kg^-1 once a day. The motor function of the rats was assessed by the BBB method after 1, 3, 7, and 14 d of drug administration. The spinal cord tissues were taken from rats executed 14 d after drug administration, and the morphological changes of the spinal cord compression site were observed by HE staining, and the expression levels of Caspase-1, GSDMD, NLRP3, PYCARD, IL-1β, and IL-18 were detected in the area of spinal cord injury by Western blot method. RESULTS: The BBB scores of the control group and the sham group were normal at all time points after modeling, which were higher than the BBB scores of the model group, the YSYSF, and the positive drug group (P<0.05). From the 3rd day after gavage, at all time points, the BBB scores of rats in the YSYSF group and the positive drug group were higher than those of rats in the model group (P<0.05). The staining pattern of HE spinal cord tissue was normal in the control group and the sham group, and the HE spinal cord in the model group was severely damaged with a large number of neuron deaths, whereas the damage to the spinal cord and neuron cells was reduced in the YSYSF group and the positive drug group. The expression levels of caspase-1, GSDMD, NLRP3, PYCARD, IL-1β and IL-18 in the spinal cord of the model group were significantly higher than those of the sham group (P<0.0001), and the expression levels of caspase-1, GSDMD, NLRP3, PYCARD, IL-1β, and IL-18 in the YSYSF group and the drug group were significantly lower than those in the model group (P<0.05). CONCLUSION YSYSF can improve the motor function of rats with degenerative cervical spinal cord disease, alleviate the pathological changes, and promote the recovery of spinal cord neurological function. The specific mechanism may be related to the inhibition of the activation of inflammatory vesicles NLRP3 and PYCARD, the reduction of the release of inflammatory factors IL-1β and IL-18, the reduction of the expression of caspase-1 and GSDMD, the reduction of cellular death, and the inhibition of inflammatory response.
