ObjectiveTo explore the efficacy and mechanisms of Sini San in the treatment of depression and liver injury based on gut microbiota. MethodsThirty-two male Sprague-Dawley （SD） rats were randomly divided into a normal group， model group （M）， Sini San group （MS， 2.5 g·kg^-1）， and fluoxetine group （MF， 2 mg·kg^-1）. Except for the normal group， rats in the other three groups were subjected to chronic unpredictable mild stress （CUMS）. After 8 weeks， the open-field test and sucrose preference test were conducted. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum corticosterone （CORT）， adrenocorticotropic hormone （ACTH）， corticotropin-releasing factor （CRF）， lipopolysaccharide （LPS）， Zonulin， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， γ-aminobutyric acid （GABA） levels in the hippocampus and prefrontal cortex， and brain-derived neurotrophic factor （BDNF） levels in the hippocampus. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect hippocampal BDNF mRNA expression. Serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） levels were measured using the ultraviolet lactate dehydrogenase method. The ultrastructure of the intestinal epithelium was observed by electron microscopy， and gut microbiota in rat feces were analyzed using 16S rDNA high-throughput sequencing. ResultsCompared with the normal group， the sucrose preference of rats in the model group was significantly reduced （P0.01）， whereas it was significantly increased in the Sini San group compared with the model group （P0.05）. Compared with the normal group， hippocampal GABA protein levels and BDNF mRNA expression in the model group were significantly decreased （P0.05）， and compared with the model group， both were significantly increased in the Sini San group （P0.05， P0.01）. Compared with the normal group， serum LPS and Zonulin levels in the model group were significantly increased （P0.05， P0.01）， and compared with the model group， Zonulin levels in the Sini San group were significantly decreased （P0.05）. No obvious changes were observed in the ultrastructure of the jejunal mucosa among groups. Compared with the normal group， widened and blurred tight junctions， sparse and shortened microvilli， and mitochondrial swelling with cristae disruption in epithelial cells were observed in the ileal and colonic mucosa of the model group， which were markedly improved in the Sini San and fluoxetine groups. The results of 16S rDNA high-throughput sequencing showed that Sini San improved CUMS-induced dysbiosis of Bacteroidetes and Proteobacteria. Correlation analysis indicated that Bacteroidetes and Proteobacteria were significantly correlated with depression-related indicators， liver function， and intestinal mucosal permeability. ConclusionSini San exerts antidepressant and hepatoprotective effects by improving Bacteroidetes and Proteobacteria and inhibiting the increase in intestinal mucosal permeability in CUMS rats.

Objective: To analyze the characteristics of imported malaria cases in Jinhua City, Zhejiang Province from 2010 to 2024, so as to provide a basis for consolidating the achievements of malaria elimination and improving prevention and control measures. Methods: Data on imported malaria cases in Jinhua City from 2010 to 2024 were collected through the Parasitic Disease Prevention and Control Information Management System of the Chinese Center for Disease Control and Prevention Information System, including basic information such as gender, age, household registration, and occupation, as well as data on disease onset, healthcare-seeking behavior, and epidemiological history. Descriptive analysis was conducted on the sources of importation, temporal distribution, population distribution, regional distribution, and the interval from disease onset to healthcare-seeking among imported malaria cases. The average annual percent change (AAPC) was used to analyze the trend in reported incidence of imported malaria in Jinhua City from 2010 to 2024. Results: A total of 581 imported malaria cases were reported in Jinhua City from 2010 to 2024, with Plasmodium falciparum malaria being the predominant type, accounting for 476 cases (81.93%). The average annual reported incidence of imported malaria in Jinhua City from 2010 to 2024 was 0.48/105, with no statistically significant overall trend (P>0.05). The majority of cases were imported from Africa, accounting for 532 cases (91.57%). A higher number of cases were reported from July to October, accounting for 258 cases (44.41%). Yiwu City reported the highest number of cases, accounting for 395 cases (67.99%). The majority of cases were males, accounting for 492 cases (84.68%), and aged 20-50 years, accounting for 487 cases (83.82%). The interval from disease onset to healthcare-seeking was more than 3 days in the majority of cases, accounting for 267 cases (45.96%). The median interval from onset to healthcare-seeking for non-Plasmodium falciparum malaria cases was 3.33 (interquartile range, 3.25) days, which was longer than that for Plasmodium falciparum malaria cases 3.00 (interquartile range, 3.00) days (P<0.05). Conclusions The overall trend in reported incidence of imported malaria in Jinhua City from 2010 to 2024 remained stable. The cases were predominantly Plasmodium falciparum malaria and imported from Africa. A higher incidence was observed in summer and autumn, in Yiwu City, and among males and young adults. The interval from disease onset to healthcare-seeking was longer for non-Plasmodium falciparum malaria cases.

BACKGROUND: Over 20 million colonoscopies are performed in China annually. An automatic clinical decision support system (CDSS) with accurate semantic recognition of colonoscopy reports and guideline-based is helpful to relieve the increasing medical burden and standardize the healthcare. In this study, the CDSS was built under a hierarchical-label interpretable classification framework, trained by a state-of-the-art transformer-based model, and validated in a multi-center style. METHODS: We conducted stratified sampling on a previously established dataset containing 302,965 electronic colonoscopy reports with pathology, identified 2041 patients' records representative of overall features, and randomly divided into the training and testing sets (7:3). A total of five main labels and 22 sublabels were applied to annotate each record on a network platform, and the data were trained respectively by three pre-training models on Chinese corpus website, including bidirectional encoder representations from transformers (BERT)-base-Chinese (BC), the BERT-wwm-ext-Chinese (BWEC), and ernie-3.0-base-zh (E3BZ). The performance of trained models was subsequently compared with a randomly initialized model, and the preferred model was selected. Model fine-tuning was applied to further enhance the capacity. The system was validated in five other hospitals with 3177 consecutive colonoscopy cases. RESULTS: The E3BZ pre-trained model exhibited the best performance, with a 90.18% accuracy and a 69.14% Macro-F1 score overall. The model achieved 100% accuracy in identifying cancer cases and 99.16% for normal cases. In external validation, the model exhibited favorable consistency and good performance among five hospitals. CONCLUSIONS The novel CDSS possesses high-level semantic recognition of colonoscopy reports, provides appropriate recommendations, and holds the potential to be a powerful tool for physicians and patients. The hierarchical multi-label strategy and pre-training method should be amendable to manage more medical text in the future.

Objective To analyze the efficacy of rTMS with different frequencies for PSD patients and analyze their EEG characteristics.Methods A total of 123 PSD patients admitted in our de-partment from May 2022 to May 2024 were recruited,and according to the frequency of rTMS,they were divided into high-frequency group(41 cases),intermediate-frequency group(41 cases)and low-frequency group(41 cases).Video fluoroscopic swallowing study(VFSS)was used to evaluate the swallowing function of patients swallowing different foods in the frontal and lateral positions.The swallowing function,motor evoked potential(MEP)of mandibular hyoid muscle,EEG characteristics and adverse reactions were compared among the groups.Results Compared with the high-frequency group,the VFSS score and MEP amplitude were decreased remarkably,while the Wadian drinking water test score and MEP latency were increased notably in the middle-frequency group and the low-frequency group(P＜0.05).The low-frequency group had signifi-cantly lower VFSS score and MEP amplitude(6.02±1.12 vs 6.57±1.01,102.25±19.81 μV vs 131.84±18.61 μV,P＜0.05),and higher Wadian drinking water test score and extended MEP latency than the intermediate-frequency group(2.03±0.31 vs 1.65±0.32,11.15±1.28 ms vs 9.21±1.36 ms,P＜0.05).After intervention,the amplitudes of the left anterior temporal lobe,the left middle temporal lobe,the middle central lobe,the left upper lobe and the right occipital lobe were gradually decreased in the high-frequency group,the middle-frequency group and the low-frequency group in order,with statistical significances(P＜0.05).Conclusion High-frequency rTMS can effectively regulate the MEP of mandibular hyoid muscle and EEG characteristics in PSD patients,improve swallowing function,and have no obvious adverse reactions,with high safety.

Acute pancreatitis(AP)is a frequently encountered acute abdominal syndrome in clinical settings,and the integrated model of traditional Chinese and Western medicine(TCM-WM)has demonstrated notable advantages in the diagnosis and treatment of AP.To systematize and standardize clinical practices related to develop clinical pathway for integrated TCM-WM diagnosis and treatment of AP,which enhances the efficiency and quality of patient care.This pathway focuses on AP,a common acute and life-threatening disease within the digestive system,and outlines that the central pathological mechanism involves pancreatic injury and localized inflammation resulting from the abnormal activation of pancreatic enzymes.It has the characteristics of rapid onset,multiple causes,and complex manifestations.Severe cases can be life-threatening.At present,conventional treatments encompass a diverse range of modalities.Moreover,traditional Chinese medicine(TCM)holds distinct advantages in alleviating relevant symptoms,and TCM-WM is gaining increasing prevalence.To enhance the standardization and consistency of diagnostic and therapeutic practices,this clinical pathway clearly delineates the target patient population,which includes individuals diagnosed with abdominal pain disorder according to TCM and with AP in accordance with WM criteria,as well as the corresponding inclusion standards.The diagnostic framework integrates both TCM and WM guidelines,and further incorporates disease staging,severity grading,and syndrome differentiation to support a comprehensive and integrated diagnostic strategy.The treatment integrates approaches from both TCM and WM.Within the WM framework,interventions consist of basic supportive care,infection control,nutritional support,and the management of complications.In the context of TCM,the protocol includes syndrome differentiation and corresponding therapeutic strategies(Distinct syndrome patterns are identified and managed during the acute and convalescent phases),such as acupuncture and retention enema.This clinical pathway addresses multiple key components,including preventive strategies,post-treatment follow-up,criteria for evaluating therapeutic efficacy,admission and discharge,admission examination protocols,discharge criteria,and the rationale for deviations or withdrawal from the pathway.It is designed to provide a systematic and standardized reference framework for relevant clinical practices.

Objective:To assess the effects of allergens on interleukin-18 (IL-18), IL-18 binding protein a (IL-18BPa), and IL-18 receptor α (IL-18Rα) expression levels in different monocyte subtypes of the peripheral blood samples of allergic asthma (AA) patients, and the correlations between the percentage of IL-18 +classical monocytes and plasma levels of pro-inflammatory cytokines. Methods:A cross-sectional study. Blood samples were collected from 28 healthy controls and 33 patients experiencing acute attack of AA based on a positive skin prick test of Henan Provincial People′s Hospital from February 2023 to April 2024. Flow cytometry was used to assess the effects of allergens on IL-18, IL-18BPa, and IL-18Rα expression levels in the classical, intermediate, and non-classical monocytes of the peripheral blood samples of AA patients. Kruskal-Wallis test and Pairwise test were used to analyze statistical significance between groups. Plasma tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) levels were estimated using Bioplex assays. Pearson correlation test was used to determine the association between the percentage of IL-18 +classical monocytes and the plasma levels of IL-1β and TNF-α. Results:Compared with healthy controls, the percentages of classical and non-classical monocytes in the peripheral blood of AA patients were reduced by 20.2% ( Z=-3.89, P<0.001) and 45.8% ( Z=-4.01, P<0.001), respectively. Allergens increased the percentages of classical, intermediate, and non-classical monocytes in AA patients in vitro by 13.1%-61.5% (all P<0.05). Compared with healthy controls, the percentages of IL-18 expression in classical monocytes of AA patients was elevated by 1.08-fold ( Z=-6.40, P<0.001), whereas the percentages of IL-18 expression in intermediate and non-classical monocytes were reduced by 52.7% ( Z=-6.40, P<0.001) and 3.23% ( Z=-3.13, P=0.001), respectively. Allergens upregulated IL-18 expression by 16.4%-67.8% in the classical and intermediate monocytes of AA patients (all P<0.05). Compared with healthy controls, IL-18BPa expression level was lower in the three monocyte subtypes of AA patients (all P<0.05). However, allergens upregulated IL-18BPa expression by 8.9% and 13.3% in the classical monocytes (both P<0.05). Compared with healthy controls, IL-18Rα expression was elevated by 1.29-fold in the classical monocytes of AA patients ( Z=-6.40, P<0.001). Allergens upregulated IL-18Rα expression by 17.6%-39.2% in the three monocyte subtypes of AA patients (all P<0.05). Plasma levels of IL-1β and TNF-α in the AA patients were increased compared to those in healthy controls (all P<0.001), and correlated with the percentage of IL-18 +classical monocytes ( r=0.451, 0.714; both P<0.05). Conclusions:Allergens may participate in the inflammatory response of AA by inducing the differentiation of monocytes and the expression levels of IL-18, IL-18BPa and IL-18Rα in different blood monocytes subtypes. Classical monocytes are the potential source of elevated plasma IL-18 level in AA patients.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.
