ObjectiveUltra performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry (UPLC-Q-TOF-MS/MS) coupled with network pharmacology and molecular docking was utilized to explore the efficacy and mechanism of action of Ermiao Situ decoction on rats with damp-heat eczema. MethodsA rat model of damp-heat eczema was established by artificial climate chamber intervention combined with sensitization induction by dinitrochlorobenzene (DNCB), and it was randomly divided into the normal group, the model group, the medium- and high-dose groups of Ermiao Situ decoction (3.40 g·kg-1 and 6.80 g·kg-1), and the prednisone acetate group (2.51 mg·kg-1), with eight rats in each group, totalling 46 rats, of which six rats were tested with the drug-containing serum. The chemical analysis of drug-containing serum from rats was carried out by UPLC-Q-TOF-MS/MS, combined with network pharmacology for the prediction of key components, core targets, and signaling pathways, and molecular docking experiments were performed by CB-Dock2 online website. The pharmacological effects of Ermiao Situ decoction in the treatment of damp-heat eczema were investigated by epitaxial indexes combined with the pathologic tissue staining method. The serum levels of gastrin (GAS), interleukin-4 (IL-4), and interleukin-13 (IL-13) were measured by enzyme-linked immunosorbent assay (ELISA). Interleukin-6 (IL-6), Janus kinase 1 (JAK1), phosphorylated (p)-JAK1, signal transduction and activation of transcription factor 3 (STAT3), and p-STAT3 protein expression level was determined by Western bolt. ResultsA total of 19 active ingredients were detected in drug-containing serum samples of rats, which were predicted to act on 198 targets for the treatment of damp-heat eczema, among which the key ingredients included rhodopsin, huangpai alkaloids, and quercetin, and the main core targets included STAT3, tumor necrosis factor (TNF), and IL-6, which were mainly involved in the cancer signaling pathway, phosphatidylinositol 3-kinase (PI3K)/protein kinase (Akt) signaling pathway, T helper 17 (Th17) cell differentiation signaling pathway, and JAK/STAT signaling pathway. The molecular docking results suggested that the key components had strong binding activities with the core targets IL-6, JAK1, and STAT3 in the JAK/STAT signaling pathway. The results of animal experiments showed that compared with those in the normal group, rats in the model group were depressed. They had loose hair, loose stools, epidermal oozing, vesiculation, and generation of thick scabs in the form of scales, decreased body weight, increased anus temperature and water intake, and increased indexes of the spleen, thymus gland, and stomach (P<0.05, P<0.01), and the lesion tissue could be seen to be hyperkeratotic, with the aggregation of inflammatory cells and nonsignificant separation of epidermis and dermis. The gastric mucosa was thinned, deficient, and structurally disorganized, and obvious inflammatory cell aggregation was seen. The levels of GAS, IL-4, and IL-13 in serum were significantly reduced (P<0.05, P<0.01), and the protein expression levels of IL-6, JAK1, p-JAK1, and p-STAT3 in the lesion tissue were significantly increased (P<0.05, P<0.01). Compared with those in the model group, rats in each administration group had stable mental states, formed feces, a clean perianal area, and basically normal epidermis. Only a small amount of scaly scabs existed, and the rats had body weight increased, with decreased anal temperature and water intake, as well as decreased spleen, thymus, and gastric indexes (P<0.05, P<0.01). Epidermal thickness was decreased, and epidermal and dermal separation boundaries were obvious, but hyperkeratotic and accumulation of inflammatory cells could still be seen. The thickness of gastric mucosa increased, and the structure was restored to varying degrees. The levels of GAS, IL-4, and IL-13 content in the serum of rats were increased to varying degrees, and the protein expression levels of IL-6, JAK1, p-JAK1, and p-STAT3 in the dermal lesion tissue were significantly decreased (P<0.05, P<0.01). ConclusionErmiao Situ decoction may exert therapeutic effects on rats with damp-heat eczema by modulating the JAK/STAT signaling pathway.

OBJECTIVE To investigate the antidepressant mechanism of Shugan hewei tang (SGHWT) based on the metabolomics of prefrontal cortex (PFC)-nucleus accumbens (NAc)-ventral tegmental area (VTA) neural circuit. METHODS Male SD rats were randomly divided into blank group, model group, SGHWT low-, medium- and high-dose groups [3.67, 7.34, 14.68 g/(kg·d), by raw material], and fluoxetine group [1.58 mg/(kg·d), positive control], with 12 rats in each group. Except for the blank group, the depression model was established by chronic unpredictable mild stress combined with individual cage housing in the remaining groups, and the corresponding drug solution or normal saline was administered via gavage during modeling, once a day, for 6 consecutive weeks. After the last administration, the body weight, sucrose preference rate, total moving distance, frequency into the center and immobility time of rats in each group were detected. Samples of PFC, NAc and VTA areas of rats in the blank group, model group, SGHWT medium-dose group and fluoxetine positive control groups were collected,and their histomorphological features were observed, and non-targeted metabolomics analysis (except for fluoxetine group)were performed and validated. RESULTS Compared with model group, the cytolysis, structural damage and other pathological damages in three brain regions of rats were significantly alleviated in each drug group, while their body weight, sucrose preference rate, total moving distance and frequency into the center were all significantly higher or longer (P<0.05), and immobility time was significantly shorter (P<0.05). The results of non-targeted metabolomics showed that a total of 78 endogenous differential metabolites were identified, with 40, 35 and 24 in the PFC, NAc and VTA regions respectively, mainly involved in amino acid, lipid and sphingolipid metabolism. The results of metabolic pathway enrichment analysis showed that SGHWT affected the neural circuits of depressed rats by regulating sphingolipid metabolism, alanine, aspartic acid and glutamic acid metabolism, saturated fatty acid biosynthesis, among which alanine, aspartic acid and glutamic acid metabolism was predominantly involved. Validation experiments showed that SGHWT significantly increased the phosphorylation levels of protein kinase B (Akt) and mammalian target of rapamycin (mTOR), and decreased the protein expression of N-methyl-D-aspartic acid receptor 1 (NMDAR1) in the NAc region of rats. CONCLUSIONS SGHWT significantly improves the depression-like behavior and attenuates pathological damage of PFC-NAc-VTA neural circuit of model rats, the mechanism of which is associated with inhibiting NMDAR1 expression and activating the Akt/mTOR signaling pathway.

Diffuse large B-cell lymphoma (DLBCL) is a highly heterogeneous disease. Although standard first-line regimens can cure >50% of patients, approximately one-third of them develop relapsed/refractory DLBCL (r/r DLBCL). Consequently, immunotherapy targeting molecular abnormalities has become pivotal for managing r/r DLBCL. The results of this review show that with advances in understanding DLBCL pathogenesis and the tumor immune microenvironment, antibody-based therapies have evolved rapidly, progressing from monoclonal antibodies (e.g., rituximab, tafasitamab) to bispecific antibodies(e.g., odronextamab,glofitamab, epcoritamab) and antibody-drug conjugate (e.g., polatuzumab vedotin, loncastuximab tesirine). These engineered agents enhance immune cytotoxicity and tumor-specific targeting, providing novel therapeutic options for r/r DLBCL patients.

OBJECTIVE:The effect of post-activation potentiation on sports performance is characterized by increased muscle mobility and increased rate of muscle force generation.In this paper,Meta-analysis is used to quantitatively evaluate the effects of post-activation potentiation on sprint speed,jumping performance,and kinetic parameters(peak impulse,peak power,maximum ground reaction force,rate of force generation,etc.)after activation of relative strength levels in the lower limbs. METHODS:Electronic databases such as CNKI,WanFang,Web of Science,PubMed,and Medline were retrieved for randomized control,random crossover,or clear grouping according to the relative strength levels of the lower limbs(non-randomized controls)on the post-activation potentiation effect after activation induced by the relative strength level of the lower limbs.Free weight equipment and rapid telescopic compound exercises were used as main intervention methods in each group.The publication time of the literature was from the inception of each database until August 5,2023.Endnote software was used to manage the literature.Literature quality assessment was conducted using the PEDro scale for randomized controlled trials and ROBINS-I 2.0 standards for non-randomized controlled trials.Revman5.4 and Stata15.0 software were used to conduct publication bias evaluation,subgroup analysis and sensitivity analysis of the extracted data,and forest plots were produced for Meta-analysis. RESULTS:Eleven documents(seven randomized controlled trials and four non-randomized controlled trials)were finally included,including 216 subjects.Overall,the methodological quality of the literature was high.According to the grouping standard of 1-repetition maximum/body mass>2 for the strong group and 1-repetition maximum/body mass≤2 for the normal group,there were 99 subjects in the strong group and 117 subjects in the normal group,all of whom were male.The positive effect of post-activation potentiation on sprint performance in the strong group was significantly higher than that in the normal group[standardized mean difference(SMD)=-1.34,95%confidence interval(CI):-1.74 to-0.93,P<0.000 01];the positive effect of post-activation potentiation on vertical jump height showed no significant difference between the strong and normal group(SMD=0.30,95%CI:-0.07 to 0.66,P=0.11);the positive effect of post-activation potentiation showed no significant difference between the strong and normal groups in terms of peak impulse(SMD=-0.07,95%CI:-0.62 to 0.47,P=0.61],peak power(SMD=0.21,95%CI:-0.29 to 0.72,P=0.12),maximum ground reaction force(SMD=0.31,95%CI:-0.20 to 0.81,P=0.16)and force generation rate(SMD=0.36,95%CI:-0.11 to 0.82,P=0.39). CONCLUSION:The post-activation potentiation effect in the strong group can significantly increase the short-distance sprint speed.The potentiation effect after activation of the relative strength level of the lower limbs has similar effects on the kinematic and kinetic parameters,including explosive vertical jump height,peak impulse,peak power,maximum ground reaction force and force generation rate.

Objective By using the computational fluid mechanic(CFD)method the tandem carotid artery stenosis(TCAS)was simulated on the model,and to compare the postoperative hemodynamic changes of different surgical procedures.Methods One patient with tandem stenosis of internal carotid artery(ICA)and common carotid artery(CCA)was selected.CFD technique was used to establish four three-dimensional(3-D)models of the carotid bifurcations,including one model of a real patient and three models of presumptive surgery.The hemodynamic analysis was performed with these models so as to explore the development mechanism of TCAS and to discuss the selection of suitable surgical plan.Results In tandem stenosis,the stenosis was preferentially formed in CCA and subsequently led to ICA stenosis.The local hemodynamic situation in TCAS was more complex and more risky than in single carotid artery stenosis.In tandem stenosis,the treatment of one stenosis site would affect the blood flow at the next stenosis site and cause restenosis or plaque rupture.Conclusion In treating patients with TCAS,CFD simulation examination should be performed when the surgical plan is formulated,which can help clinicians to predict the postoperative changes in blood flow and to choose the appropriate surgical plan.
