OBJECTIVE To conduct rapid health technology assessment (HTA) of ulinastatin (UTI), and to evaluate the efficacy, safety and cost-effectiveness of UTI in the treatment of acute pancreatitis (AP). METHODS Retrieved from PubMed, Embase, the Cochrane Library, CNKI, Wanfang database, CBM and official websites of HTA institutions, the systematic review (SR)/meta-analysis, economic evaluation and HTA reports of UTI in the treatment of AP were collected from the inception to Apr. 2024. Two researchers independently conducted screening, quality evaluation and data extraction according to the admission and exclusion criteria, and descriptive analysis was adopted to analyze and summarize the data. RESULTS A total of 19 studies were included, involving 15 SR/meta-analysis and 4 economic studies, and no HTA report was retrieved. In the treatment of AP, UTI showed clear advantages over conventional treatment alone in terms of improving the overall effective rate, shortening the recovery time of amylase, reducing the time required to relieve abdominal pain and distension, lowering the mortality rate, and decreasing the average hospital stay. Compared to other positive drugs (carbendate mesylate, octreotide, somatostatin, etc.), its efficacy is similar, with a favorable safety profile. As far as the current research was concerned, UTI had obvious economic advantages over other positive drugs. CONCLUSIONS UTI is safe and effective in the treatment of AP, and has economic advantages.

OBJECTIVE To explore the mechanism of modified Xianfang huoming decoction in the treatment of sepsis- induced liver injury from the perspective of gut microbiota and metabolites. METHODS Sixty SD rats were divided into blank group (normal saline), model group (normal saline), positive control drug group (Dexamethasone tablet, 5.0 mg/kg), modified Xianfang huoming decoction high-dose, middle-dose and low-dose groups (6.0, 3.0, 1.5 g/kg, calculated by crude drug) according to equilibrium-partitioning approach of body mass, with 10 rats in each group. They were given relevant drug/normal saline 10 mL/ kg, once a day, for consecutive 14 days. After the last medication, except for blank group, other groups were given intraperitoneal injection of lipopolysaccharide 10 mg/kg to induce sepsis model. Twelve hours after modeling, serum levels of inflammatory indexes in rats [interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α)] and liver function indicators [total cholesterol (TC), triglyceride (TG), aspartate transaminase (AST), alanine transaminase (ALT)] were detected. The changes of gut microbiota and liver metabolites in rats were analyzed by 16S rRNA technology and liver metabolomics. RESULTS Modified Xianfang huoming decoction could significantly improve the indexes of serum inflammatory indexes and liver function in rats with sepsis-induced liver injury (P<0.05 or P<0.01); there was a significant callback effect on the relative abundance of 11 genera of bacteria (such as Akkermansia, Lactobacillus and Bilophila) among the 5 dominant phyla(P<0.05 or P<0.01). Twelve metabolites related to liver injury caused by sepsis were identified, such as glycine cholic acid, phosphatidylcholine, taurine (P<0.05 or P<0.01), mainly involving glycerol phospholipid metabolism, purine metabolism and primary bile acid metabolism. CONC LUSIONS Modified Xianfang huoming decoction can improve liver injury induced by sepsis by regulating gut microbiota and liver metabolites.

Objective:To observe the characteristics of the phagocytosis and bactericidal function of multidrug-resistant Mycobacterium tuberculosis(MDR- Mtb)-infected macrophage model, and the changes of the immune response and metabolic function in the process of phagocytosis and bactericidal function, aiming to provide reference for studying the role and mechanism of macrophages in the occurrence and development of multidrug-resistant tuberculosis(MDR-TB). Methods:We established MDR- Mtb and H37Rv-infected macrophage models, and used the colony-forming unit (CFU), Magnetic Luminex ? Assay and Cholesterol Assay kit to observe the effects on phagocytosis and bactericidal function, the secretion of Th1(IL-12/23 p40, IL-27 and TNF-α) and Th2 cytokines (IL-6 and IL-10) and cholesterol metabolism. The data were analyzed by SPSS25.0 software. The data were expressed as Mean± SD and analyzed by t test or F test. P<0.05 was considered statistically significant. Results:(1) After MDR- Mtb-infected macrophages, the intracellular CFU gradually increased and reached the highest at 24 h, while the extracellular CFU gradually decreased and reached the lowest at 24 h. The intracellular CFU at 48 h was lower than that at 24 h, while the extracellular CFU was higher than that at 24 h ( P<0.05). Both intracellular and extracellular CFU at 48 h were close to those at 4 h ( P>0.05). The intracellular CFU was lower than the H37Rv group at 8-48 h, while the extracellular CFU was higher than the H37Rv group ( P<0.05). (2) The level of IL-12/23 p40, IL-27, TNF-α, IL-6 and IL-10 of MDR-TB group were higher than those of blank group ( P<0.05), but the level of TNF-α and IL-6 at 24 h and 48 h were higher than that at 4 h ( P<0.05). IL-12/23 p40 and TNF-α at 48 h and IL-6 at 24 h were lower than those of the H37Rv group, while IL-27 at 48 h was higher than that of the H37Rv group ( P<0.05). (3) The levels of cholesterol of MDR-TB group at 24 h and 48 h were lower than those of 4 h and blank group ( P<0.05), but the level of cholesterol was similar to the H37Rv group at any time ( P>0.05). (4) TNF-α reached the highest when the intracellular CFU reached the highest at 24 h, and IL-6 reached the highest when the intracellular CFU decreased at 48 h. With the decreasing of cholesterol expression, the intracellular CFU increased and then decreased. Conclusions:MDR- Mtb could induce the phagocytosis and bactericidal function of macrophages, increase the expression of Th1 and Th2 cytokines and promote the utilization and consumption of cholesterol, but this function was weaker than that of H37Rv strain.
