Tear film hyperosmolarity plays a core role in the development of dry eye disease (DED) by mediating the disruption of ocular surface homeostasis and triggering inflammation in ocular surface epithelium. In this study, the mechanisms involving the hyperosmolar microenvironment, glycolysis mediating metabolic reprogramming, and pyroptosis were explored clinically, in vitro, and in vivo. Data from DED clinical samples indicated that the expression of glycolysis and pyroptosis-related genes, including PKM2 and GSDMD, was significantly upregulated and that the secretion of IL-1β significantly increased. In vitro, the indirect coculture of macrophages derived from THP-1 and human corneal epithelial cells (HCECs) was used to discuss the interaction among cells. The hyperosmolar environment was found to greatly induce HCECs' metabolic reprogramming, which may be the primary cause of the subsequent inflammation in macrophages upon the activation of the related gene and protein expression. 2-Deoxy-d-glucose (2-DG) could inhibit the glycolysis of HCECs and subsequently suppress the pyroptosis of macrophages. In vivo, 2-DG showed potential efficacy in relieving DED activity and could significantly reduce the overexpression of genes and proteins related to glycolysis and pyroptosis. In summary, our findings suggested that hyperosmolar-induced glycolytic reprogramming played an active role in promoting DED inflammation by mediating pyroptosis.

Objective: To observe the effect of moxibustion on the colonic mucosal barrier of rats with ulcerative colitis (UC) induced by dextran sulfate sodium (DSS). Methods: Forty male Sprague-Dawley rats were randomly divided into a normal group and a modeling group, with 20 rats in each group. Rats in the modeling group were subjected to preparing experimental UC models by drinking 4% DSS for seven consecutive days. Two modeled rats and two normal rats were randomly selected for model identification. After the success of UC model was confirmed, the remaining 18 modeled rats were randomly divided into three groups, a model group, a model + herbal cake-partitioned moxibustion group, and a model + mild moxibustion group, with six rats in each group; the remaining normal rats were randomly divided into three groups, a normal group, a normal + herbal cake-partitioned moxibustion group, and a normal + mild moxibustion group, with six rats in each group. After 7 d of intervention with the herbal cake-partitioned moxibustion or the mild moxibustion, hematoxylin-eosin (HE) staining technique was used to observe the pathological changes of colon tissue under a light microscope; Western blotting and/or immunohistochemical techniques were used to detect the protein expression levels of Occludin, Claudin, junction adhesion molecular 1 (JAM1), mucin 2 (MUC2), and transforming growth factor beta1 (TGF-β1) in rat colon tissue. Results: Compared with the normal group, the colon tissue was severely damaged, the pathological score was significantly increased, and the protein expression levels of Occludin, Claudin, JAM1, MUC2, and TGF-β1 were significantly decreased in the model group (P<0.01); while there were no significant differences in the colonic histopathological score, protein expression levels of Occludin, Claudin, JAM1, MUC2, and TGF-β1 in the normal + herbal cake-partitioned moxibustion group and the normal + mild moxibustion group (P>0.05). Compared with the model group, the model + herbal cake-partitioned moxibustion group and the model + mild moxibustion group showed repaired colon tissue, ulcer healing, significantly reduced pathological score, and significantly increased protein expression levels of JAM1, MUC2, and TGF-β1 (P<0.05); the Occludin protein expression level in the colon tissue of the model + mild moxibustion group was increased (P<0.01). Conclusion: Neither herbal cake-partitioned moxibustion nor mild moxibustion influences the colonic histopathology and intestinal mucosal barrier-related protein expression in the normal rats; both herbal cake-partitioned moxibustion and mild moxibustion can up-regulate the protein expression levels of JAM1, MUC2, and TGF-β1 in the colon tissue of UC rats. Mild moxibustion can up-regulate Occludin protein expression. This may be a mechanism of moxibustion in reducing colonic mucosa inflammation in UC.

OBJECTIVE To study the improvement effects and mechan ism of thalidomide on Alzheimer ’s disease (AD)model of Caenorhabditis elegans . METHODS In this study ,the BR 5270 strain of C. elegans was used as AD model and BR 5271 strain as the control. The effects of thalidomide (0.5,2.0,6.0,15.0 mg/mL)on the motility of BR 5270 strains of C. elegans were studied by the basal slowing response assay ;the effects of thalidomide (0.5,2.0,6.0,15.0 mg/mL)on the survival time of BR 5270 strain of C. elegans were studied by life assay ;the effects of thalidomide (0.5,2.0,6.0 mg/mL)on learning and memory ability of BR 5270 strain of C. elegans were studied by short-term and long-term learning and memory assay. RT-PCR technology was used to study the effects of thalidomide (0.5,2.0,6.0 mg/mL)on mRNA expression of phosphatidylinositol 3-kinase(PI3K)/protein kinase B (Akt)signal pathway related genes (Age-1,Akt-1,Gsk-3)and calpain homologous gene (Clp-1)in BR 5270 strain of C. elegans . RESULTS After the intervention of thalidomide ,oscillation times of BR 5270 strain of C. elegans increased significantly within 30 s (except for 0.5 mg/mL group ),and the 10% of maximum life span was prolonged significantly (only 0.5 mg/mL group );the short-term and long-term learning indexes were improved significantly (only 6.0 mg/mL group );mRNA expression of Age-1 and Akt-1(except for 0.5,2.0 mg/mL groups )were increased significantly ,mRNA expression of Gsk-3(except for 0.5 mg/mL group ) and Clp-1 were decreased (P<0.05 or P<0.01). CONCLUSIONS Thalidomide can ameliorate the dyskinesia of AD model of C. elegans,prolong the lifespan of this strain ,and enhance its learning and memory ability. Its mechanism of action may be related to activation of PI 3K/Akt signaling pathway and inhibition of calpain.

" Day surgery hospital-community joint follow-up model " results newly from the deepening implementation of the hierarchical medical system policy. It is designed to follow up the patients discharged from hospital but not fully recovered in time to ensure the prevention of adverse events after surgery. It can also improve the quality and efficiency of follow-up, and ensure the safety and integrity of the whole day operation management. In this context, through a comparative study of 720 patients discharged from daytime surgery in the region, patients in the combined follow-up group were followed up by telephone on the 3rd day after the operation by nurses from the day surgery ward. On the 10th and 20th days after the operation, the family doctor from the community health service center will visit the patient at home and follow up the patient by telephone. One month later, the patient returned to the hospital for follow-up consultation. Follow-up results show day surgery hospital-community joint mode as a helpful aid in keeping track of the patients postoperative rehabilitation, reducing complications and handling in time, while improving the ambulatory surgery perioperative safety.
