OBJECTIVE： To investigate the effects of Buyang huanwu decoction on endothelial-mesenchymal transformation （EndMT） of lung tissue in idiopathic pulmonary fibrosis （IPF） model rats， and to explore its potential mechanism. METHODS： Male SD rats were randomly divided into normal group， model gorup， dexamethasone group [0.405 mg/（kg·d）]， Buyang huanwu decoction low-dose， medium-dose and high-dose groups [6.435， 12.87， 25.74 g/（kg·d）， by raw material]， with 8 rats in each group. Except for normal group， other groups were given endotracheal injection of bleomycin to induce IPF model. On the second day after modeling， normal group and model group were given water intrgastrically [10 mL/（kg·d）]； administration groups were given relevant medicine intragastrically， once a day， for consecutive 28 days. 24 h after last medication， the expression of endothelial cell markers [platelet endothelial cell adhesion molecule 1， vascular endothelial cell cadherin] and interstitial cell markers [α-smooth muscle actin， fibroblast specific protein 1] were detected by immunohistochemistry method. The expression of Notch4 and DLL4 in lung tissue of rats were detected by Western blotting assay. RESULTS： Compared with normal group， the expression of endothelial cell markers were decreased significantly in lung tissue of model group， while the expressipon of interstitial cell markers， Notch4 and DLL4 were increased significantly （P＜0.01）. Compared with model group， the expression of endothelial cell markers in lung tissue of rats were increased significantly in administration groups， while Buyang huanwu decoction low-dose group was significantly lower than dexamethasone group； the expression of interstitial cell markers， Notch4 and DLL4 were decreased significantly， while Buyang huanwu decoction low-dose group was significantly higher than dexamethasone group （P＜0.05 or P＜0.01）. CONCLUSIONS： Buyang huanwu decoction can relieve IPF of model rats by intervening in EndMT， the mechanism of which may be associated with inhibiting DLL4/Notch4 singaling pathway.

Objective:To evaluate the clinical characteristics and prognosis of febrile convulsions (FS) in children during the epidemic period of novel coronavirus Omicron variant.Methods:A retrospective analysis was conducted on the clinical data of pediatric patients diagnosed with FS at Changsha Central Hospital Affiliated to University of South China from February 1, 2022 to January 31, 2023. The clinical characteristics and prognosis of FS patients caused by Omicron variant infection (observation group) were compared with those caused by non Omicron variant infection (control group).Results:A total of 131 cases in the observation group and 341 cases in the control group; The proportion of children aged 12-36 months in the observation group was lower than that in the control group ( P<0.05), and the proportion of children aged ≥60 months was higher than that in the control group ( P<0.05). Most of the FS in the observation group occurred within 24 hours of fever (128/131, 97.7%), with a statistically significant difference compared to the control group ( P<0.05), and most of them were generalized tonic clonic seizures (127/131, 96.9%), with only one seizure during the course of the disease (114/131, 87.0%), consistent with the characteristics of simple FS. The main clinical symptoms of FS patients in the observation group were upper respiratory tract infections (108/131, 82.5%), which were significantly higher than those in the control group (164/341, 48.1%), while the incidence of lower respiratory tract infections was lower than that in the control group ( P<0.05). 369 pediatric patients were followed up by phone or outpatient visits, with 98 cases in the observation group and 2 cases experiencing recurrence. There was no recurrence in the group aged ≥60 months; A total of 271 cases were followed up in the control group, with 9 cases experiencing recurrence. Conclusions:The number of children with FS caused by novel coronavirus Omicron variant has increased sharply, and the proportion of late onset FS patients has increased significantly. Most of them are upper respiratory tract infections. Convulsions usually occur within 24 hours of fever, and the prognosis is good.

Glycosphingolipids (GSLs) are widely distributed in the phospholipid bilayer of various cell membranes, which play an important role in maintaining cell membrane stability, and regulate various cellular processes including adhesion, proliferation, apoptosis and recognition, as well as participate in various cellular activities. In addition, GSLs are not only involved in the process of apoptosis, but also regulate multiple signals in tumorigenesis and tumor development. The tumor-associated GSLs are expected to be used as diagnostic markers and immunotherapeutic targets for malignant tumors. These findings have important implications for the study of apoptosis and provide the new direction of tumor therapy. This review summarized the latest research progress of GSLs-mediated apoptosis and its effect on the genesis, development and metastasis of tumor cells. Moreover, we discussed the metabolic pathway of GSLs-mediated apoptosis and its application in tumor therapy, as well as the development prospect of targeted therapy strategies based on GSLs.

Objective To analyze the role of lienal polypeptide injection in acute lung injury induced by lipopolysaccharide (LPS) in rats. Methods Eighty male SD rats were randomly allocated into 4 groups: a LPS group, a control group, a lienal polypeptide group and a LPS+ lienal polypeptide group (20 rats in each group). Lienal polypeptide or normal saline was given with an intramuscular injection 30 min after an intraperitoneal injection of LPS (5 mg/kg). The severity of pulmonary injury was evaluated 4 h after LPS challenge by enzyme-linked immunosorbent assay (ELISA), wet-to-dry weight ratio, hematoxylin and eosin (HE) staining, TUNEL and Western blotting. Results Lienal polypeptide injection treatment significantly attenuated LPS-induced pulmonary histopathologic changes, alveolar hemorrhage, and neutrophil infiltration. Moreover lienal polypeptide injection significantly suppressed LPS-induced activation of metastasis-associated protein-1 (MTA1). Conclusion Lienal polypeptide injection is demonstrated to protect rats from LPS-induced acute lung injury by the expression of MTA1.
