ObjectiveTo investigate the effects of Simiaowan on intestinal barrier function and adenosine triphosphate (ATP) binding cassette transporter G2 (ABCG2) expression in hyperuricemic (HUA) rats, and elucidate its therapeutic mechanisms. MethodsForty male Sprague Dawley (SD) rats were randomized into a normal group, a model group, low-dose (282.6 mg·kg-1) and high-dose (565.2 mg·kg-1) Simiaowan groups, and a Benzbromarone (4.7 mg·kg-1) group. The HUA model was established via intraperitoneal injection of potassium oxonate (ip) combined with oral gavage of hypoxanthine (ig) for 14 days. Following modeling, treatments were administered for 14 days. Samples were collected and weighed 4 h after final dosing. Blood uric acid and hepatic function were analyzed. Histopathological changes were evaluated by hematoxylin-eosin (HE) staining, and Chiu's scoring was conducted. Enzyme-linked immunosorbent assay (ELISA) quantified tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), lipopolysaccharide (LPS), diamine oxidase (DAO), and D-lactic acid (D-LA) levels. Real-time polymerase chain reaction (Real-time PCR), Western blot, and immunohistochemistry assessed the expression of Claudin-1, Occludin, occludens-1 (ZO-1), and ABCG2 mRNAs and proteins. 16S rDNA amplicon sequencing characterized ileal microbiota. ResultsCompared with the normal group, the model group exhibited epithelial shedding in the ileal villus, structural disruption, infiltration of extensive inflammatory cells, and significantly elevated Chiu's scores (P<0.01). The DAO, TNF-α, IL-6, IL-1β, LPS, and D-LA levels in the ileum were markedly increased (P<0.01), while mRNA and protein expressions of Claudin 1, Occludin, ZO-1, and ABCG2, as well as positive staining area and proportion, were significantly reduced (P<0.01). Compared with the model group, the Simiaowan groups at all doses showed improved epithelial damage in the ileal villus, significantly lowered Chiu's scores (P<0.01), significantly reduced DAO, TNF-α, IL-6, IL-1β, LPS, and D-LA levels in the ileum (P<0.01), and upregulated mRNA and protein expressions of Claudin 1, Occludin, ZO-1, and ABCG2, as well as positive staining area and proportion (P<0.01). The 16S rDNA results showed that in the model group, the α-diversity index of the ileal microbiota was increased, and species diversity and richness were enhanced, with microbiota dysfunction observed. The community structure of the gut microbiota was significantly different from that of the normal microbiota. The abundance of probiotics was decreased, and the abundance of pathogenic bacteria was increased, with butyrate-producing bacteria showing a low abundance. In contrast, Simiaowan at all doses reduced species diversity and richness, regulated microbiota dysfunction, and promoted the shift of the structure of the gut microbiota community towards a normal one. This increased the abundance of beneficial bacteria, decreased the abundance of harmful bacteria, and restored the abundance of butyrate-producing bacteria. ConclusionSimiaowan enhances ileal uric acid excretion and further alleviates HUA by modulating the gut microbiota composition to improve the intestinal barrier and upregulate the expression of the urate transporter ABCG2 in HUA rats.

OBJECTIVE To investigate the efficacy and safety of Wuling capsules combined with fluoxetine in the treatment of adolescents with first-episode moderate-to-severe depressive disorder accompanied by insomnia. METHODS The clinical data of 476 adolescents with first-episode moderate-to-severe depression accompanied by insomnia admitted to our hospital from June 2022 to May 2025, were retrospectively collected. According to the initial treatment regimen, patients were divided into a control group (241 cases, treated with fluoxetine alone) and an observation group (235 cases, treated with Wuling capsules combined with fluoxetine). The depression severity (Hamilton Depression Rating Scale-17 Item and the Self-Rating Depression Scale scores), sleep quality (Pittsburgh Sleep Quality Index score, sleep latency, wake after sleep onset, total sleep time, sleep efficiency), serum neuroendocrine indicator (cortisol) and inflammatory markers (C-reactive protein, interleukin-6) were compared between the two groups before treatment and at 4th and 8th weeks of treatment. The effective rate at 8th weeks and the occurrence of adverse drug reactions (ADRs) were also compared between the two groups. RESULTS Before treatment, there were no significant differences in depression severity, sleep quality, serum neuroendocrine indicator, and inflammatory markers between the two groups ( P >0.05). At 4th and 8th weeks, both groups showed significant improvement in these indicators compared to those before treatment, with the observation group demonstrating significantly greater improvement than the control group at the corresponding time points ( P <0.05). At 8th week, the eff ective rate of the observation group was 90.21%, significantly higher than 80.50% in the control group ( P <0.05). The incidence of nausea, headache, fatigue, dry mouth, and palpitations, as well as the total incidence of ADRs, did not differ significantly between the two groups ( P >0.05). CONCLUSIONS Wuling capsules combined with fluoxetine can significantly improve the effective rate in adolescents with first-episode moderate-to-severe depression accompanied by insomnia, accelerate the relief of depressive symptoms, improve sleep quality, and reduce serum neuroendocrine indicator and inflammatory markers, with a favorable safety profile.

OBJECTIVE:
To observe the therapeutic effect of electroacupuncture (EA) in improving early enteral nutrition tolerance in patients with acute pancreatitis (AP) under the concept of accelerated rehabilitation, and to explore the related mechanism based on the changes in autonomic nerve characteristics.
METHODS:
A total of 42 patients with AP were randomized into an observation group (21 cases, 1 case dropped out) and a control group (21 cases, 1 case dropped out). The control group received standard basic treatment for AP. On the basis of the treatment in the control group, EA was applied in the observation group, bilateral Zusanli (ST36), Yixian point (Extra), Tianshu (ST25), Neiguan (PC6) and Zhongwan (CV12) were selected as the main points, and the supplementary points were selected according to syndrome differentiation. Ipsilateral Zusanli (ST36) and Yixian point (Extra) were connected to EA, using discontinuous wave, in frequency of 2 Hz, 30 min a time, once a day for 6 continuous days. The enteral nutrition tolerance score was observed before treatment and after 3 and 5 days of treatment; the visual analogue scale (VAS) score for abdominal pain was observed before treatment and after 3 days of treatment; the time of reaching the feeding goal and hospital stay was recorded; the levels of C-reactive protein (CRP) and amylase were measured before treatment and after 5 days of treatment; the heart rate variability (HRV) indexes (standard deviation of NN intervals [SDNN], average standard deviation of NN intervals [SDANN], root mean square of successive NN interval differences [rMSSD], low frequency [LF] and high frequency [HF], ratio of low frequency to high frequency [LF/HF]) were monitored in the two groups.
RESULTS:
After 3 and 5 days of treatment, the enteral nutrition tolerance scores were decreased compared with those before treatment in both groups (P<0.01), the reductions in the observation group were larger than those in the control group (P<0.01). After 3 days of treatment, the VAS scores for abdominal pain were decreased compared with those before treatment in both groups (P<0.01), the reduction in the observation group was larger than that in the control group (P<0.01). The time of reaching the feeding goal and hospital stay in the observation group was shorter than that in the control group (P<0.05). After 5 days of treatment, the CRP and amylase levels were decreased compared with those before treatment in both groups (P<0.01), the reduction of CRP level in the observation group was larger than that in the control group (P<0.01). In the observation group, SDNN, SDANN and LF/HF were lower than those in the control group (P<0.05, P<0.01), while rMSSD was higher than that in the control group (P<0.01). SDNN, SDANN and LF/HF were positively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.05), while rMSSD was negatively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.01).
CONCLUSION
Electroacupuncture can improve enteral nutrition tolerance in patients with AP by regulating autonomic nervous function, alleviating the inflammation, promoting accelerated recovery, and reducing the length of hospital stay.

Objective To screen key autophagy-related genes in alcoholic hepatitis (AH) and investigate potential biomarkers and therapeutic targets for AH. Methods Two AH gene chips in Gene Expression Omnibus (GEO) and autophagy-related data sets obtained from MSigDB and GeneCards databases were used, and the key genes were verified and obtained by weighted gene co-expression network analysis (WGCNA). The screened key genes were subject to gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), protein-protein interaction (PPI) and immune infiltration analyses. Messenger RNA (mRNA)- microRNA (miRNA) network was constructed to analyze the expression differences of key autophagy-related genes during different stages of AH, which were further validated by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) in the liver tissues of AH patients and mice. Results Eleven autophagy-related genes were screened in AH (EEF1A2, CFTR, SOX4, TREM2, CTHRC1, HSPB8, TUBB3, PRKAA2, RNASE1, MTCL1 and HGF), all of which were up-regulated. In the liver tissues of AH patients and mice, the relative expression levels of SOX4, TREM2, HSPB8 and PRKAA2 in the AH group were higher than those in the control group. Conclusions SOX4, TREM2, HSPB8 and PRKAA2 may be potential biomarkers and therapeutic targets for AH.
