Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Objective:To determine the effect of gastrodin(GAS)on toll-like receptor 4(TLR4)expression in mi-croglia after hypoxic-ischemic brain damage.Methods:Hypoxia-ischemic brain damage(HIBD)model was established in neonatal rat in vivo.Thirty 3 d SD rats of were randomly divided into there groups:Sham group,HIBD model group,HIBD model+gastrodin intervention group(HIBD+G).Oxygen glucose deprivation(OGD)model was established in BV2 cells in vitro,Control group(Control),oxygen glucose deprivation group(OGD),OGD+gastrodin intervention group(OGD+G)were randomly set in vitro.Both Western Blot and immunofluorescence staining techniques were used to detect the expression of TLR4 in cells of each group in vitro and in the left corpus callosum region in vivo.Results:The expression of TLR4 was significantly increased in OGD-induced microglia.After gastrodin intervention,TLR4 expression was decreased significantly(P＜0.05).Conclusion:GAS can inhibit the expression of TLR4 in activated microglia and thus play a neuroprotective role in HIBD.

Objective To investigate the relationship between insomnia,gastrointestinal symptoms,and glycosylated hemoglobin(HbA1c)levels in individuals diagnosed with type 2 diabetes mellitus(T2DM),as well as the related influencing factors.Methods A total of 910 T2DM patients treated in our multicenter from January 2022 to December 2022 were enrolled in this study.General information(gender,age,smoking and drinking history,exercise,course of disease,treatment and complications),HbA1c,Athens Insomnia Scale(AIS)scores and Gastrointestinal Symptoms Rating Scale(GSRS)scores of patients were collected.The differences of sleep and gastrointestinal symptoms between groups were analyzed,and the correlation between the differences and HbA1c was analyzed.Furthermore,the risk factors for non-standard HbA1c were analyzed.Results The AIS score and GSRS score in the HbA1c control group were less than those in the non-standard group(P＜0.01).Insomnia was reported by 37.0％of T2DM patients,and the HbA1c level in the insomnia group was significantly higher than that in the non-insomnia group(10.00％±2.38％vs.8.26％±1.73％,P＜0.01).Gastrointestinal symptoms were present in 57.5％of T2DM patients,and the HbA1c levels in the group with gastrointestinal symptoms were significantly higher than those in the group without gastrointestinal symptoms(9.26％±2.23％vs.8.43％±1.98％,P＜0.01).Furthermore,26.3％of T2DM patients experienced both insomnia and gastrointestinal symptoms.Remarkably,the HbA1c levels in the group with both insomnia and gastrointestinal symptoms were significantly higher than those in the group without either condition(10.18％±2.44％vs.8.45％±1.86％,P＜0.01).Correlation analysis demonstrated a significant association between sleep quality,gastrointestinal function,and HbA1c levels(P＜0.01).The logistic regression analysis result revealed that age,GSRS score,AIS score,and the presence of insomnia combined with gastrointestinal symptoms were independent risk factors for predicting HbA1c≥6.5％(P＜0.01).Having both insomnia and gastrointestinal symptoms concurrently was the strongest risk factor for substandard HbA1c control,and the risk of blood sugar control may increase about 5 times when both appear together.Conclusion Insomnia and gastrointestinal symptoms are common comorbidities in T2DM patients,showing a cross-interfering relationship,and they appear together with poor blood sugar control,interact causally,and amplify each other.

Objective To develop multimodal joint cognitive representations for the research of visual cognitive activities of the brain,enhance the classification performance of visual information cognitive representations,predict brain electro-encephalogram(EEG)responses from visual image features,and decode visual images from EEG signals.Methods A architecture combining a multimodal variational autoencoder network with the Mixture of Product Experts(MoPoE)approach and with a style generation adversarial network based on adaptive discriminator augmentation(Style-GAN2-ADA)was used for facilitating the learning of cognitive representations and the encoding and decoding of EEG signals.This framework not only catered to classification tasks but also enabled cross-modal generation of images and EEG data.Results The present study integrated features from different modalities,enhancing the classification accuracy of cognitive representations of visual information.By aligning the feature spaces of diverse modalities into a cohesive latent space,cross-modal generation tasks were made possible.The cross-modal generation results of EEG and images,derived from this unified latent space,outperformed the one-way mapping methods that involved transition from one modality to another employed in previous research.Conclusion This study effectively integrates and aligns information from various modalities,enabling the classification performance of joint cognitive representations beyond any single modality.Moreover,the study demonstrates superior outcomes in cross-modal generation tasks compared to modality-specific unidirectional mappings,which is expected to offer a new line of thought for the effective unified encoding and decoding modeling of visual cognitive information in the brain.

Syndrome of dampness-heat of spleen and stomach is one of the complex syndromes of the spleen and stomach,which is difficult to differentiate and treat in TCM.According to the theoretical connotation of"attacking it according to its combination",it is suggested that the syndrome of dampness-heat of spleen and stomach should be comprehensively differentiated and treated from five aspects,including"attacking the visible pathogens combined with the invisible ones"(removing dampness and warming yang),"treating the fu-organs sharing interior-exterior relationship with zang-organs"(clearing away damp-heat pathogens of stomach with drugs of bitter taste and cold property),"formulating the treatment according to the likes and dislikes of the five internal organs"(developing a life adjustment plan favored by the spleen and stomach),"administrating drug according to the five organs"(medications according to the spleen and stomach),"weighing the severity and applying the treatment"(pay attention to the details,and treating according to syndrome differentiation).A clinical case is exampled,with the purpose to provide reference for the prevention and treatment of syndrome of dampness-heat of spleen and stomach.

Objective To investigate the risk factors for pulmonary embolism (PE)in patients with acute spinal cord injury (ASCI).Methods A case-control design was adopted in this study.Basic information,injury cause,injury site,imaging and laboratory examination results and other relevant data of 840 ASCI patients admitted to 3 affiliated hospitals of Army Medical University from January 2018 to August 2023 were collected.According to occurrence of PE or not,these patients were divided a PE group (n=83) and a non-PE group (n=757).Univariate analysis was performed on 37 risk factors including gender,age,length of hospital stay,length of intensive care unit (ICU)stay,cause of injury,and so on,and then multivariate logistic regression analysis was applied to analyze these selected significant variables.Results Univariate analysis showed that 24 factors such as age,length of hospital stay,lower limb fracture,pulmonary contusion and infection,shock and number of operations were related to the occurrence of PE in ASCI patients (P<0.05).Binary logistic regression analysis indicated that age (P=0.000,OR=1.957,95％CI:1.532～2.499),length of ICU stay (P=0.000,OR=2.561,95％CI:1.728～3.794),number of operations (P=0.015,OR=1.814,95％CI:1.124～2.927),spinal fixation (P=0.004,OR=0.370,95％CI:0.189～0.724),restrictive position (P=0.000,OR=21.269,95％CI:5.276～85.740),platelet count (P=0.000,OR=1.553,95％CI:1.236～1.951),D-dimer level (P=0.000,OR=1.600,95％CI:1.376～1.860)and prothrombin time (P=0.025,OR=2.756,95％CI:1.138～6.670)were independent risk factors for PE in the patients.Conclusion The mortality of the ASCI patients with PE is significantly higher than those without.Age,length of ICU stay,number of operations,spinal fixation,restrictive position,platelet count,D-dimer level and prothrombin time are closely associated with PE in ASCI patients.

Objective To systematically evaluate relevant guidelines on calories and 3 nutrients allocations during pregnancy in patients with gestational diabetes mellitus,and to compare the similarities and differences in recommendations between these guidelines.Methods Domestic and foreign guideline networks,websites of specialist associations related to diabetes,obstetrics and gynecology,as well as databases,were systematically searched from January 2010 to June 2022.There were 2 appraisers who used the Appraisal of Guidelines for Research &Evaluation Ⅱ to evaluate the quality of guidelines and then used the content analysis method to synthesize the recommendations of each guideline and compare similarities and differences.Results This study included 18 guidelines with fair overall quality(10 with grade A,2 with grade B and 6 with grade C).The guidelines provided recommendations in 5 aspects of meal allocation,calories,carbohydrates,proteins,and fats,totaling 57 recommendations.While the recommendations for meal allocation were consistent across guidelines,there were significant differences in the recommendations for calories and the 3 major nutrients.Conclusion The recommendations regarding the distribution of calories and the 3 major nutrients mostly rely on expert consensuses,with low-quality evidence but mostly strong recommendations.These guidelines exhibit significant variations from one to another.Consequently,future studies with higher quality on the distribution of calories and 3 nutrients should be conducted,and high-quality evidence-based nutrition guidelines for gestational diabetes should be developed in China.

Objective To investigate the efficacy of continuous hepatic arterial infusion chemotherapy (HAIC) with the FOLFOX regimen and its multimodality therapeutic regimen in the treatment of patients with advanced hepatocellular carcinoma, as well as the influencing factors for prognosis. Methods A retrospective analysis was performed for the clinical data of 66 patients with advanced hepatocellular carcinoma who received continuous HAIC with FOLFOX regimen in Nanfang Hospital, Southern Medical University, from September 2018 to November 2021. The patients were observed in terms of objective response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), and median overall survival (mOS) after treatment, and treatment-related adverse reactions were recorded. For the patients with portal vein tumor thrombus, the effect of the treatment on portal vein tumor thrombus was assessed. The Kaplan-Meier method was used for survival analysis, and the Cox regression analysis was used to investigate the influencing factors for prognosis. Results According to the RECIST1.1 criteria, FOLFOX-HAIC and its multimodality therapeutic regimen achieved an ORR of 33.3% (22/66) and a DCR of 86.4% (57/66) in the treatment of 66 patients with advanced hepatocellular carcinoma, with an mPFS time of 8.2 months and an mOS time of 22.1 months. Among the 39 patients with portal vein tumor thrombus, 2 achieved complete remission, 8 achieved partial remission, 24 achieved stable disease, and 5 had disease progression, with an ORR of 25.6% (10/39) and a DCR of 87.2% (34/39). The main adverse reactions included gastrointestinal reactions (16.7%, 11/66), pyrexia (12.1%, 8/66), liver area pain (10.6%, 7/66), bone marrow suppression (3.0%, 2/66), and contrast agent allergy (3.0%, 2/66), and there were no grade > Ⅳ toxic or side effects or deaths caused by such complications. The Cox regression analysis showed that extrahepatic metastasis (hazard ratio [ HR ]=2.668, 95% confidence interval [ CI ]: 1.357-5.245, P < 0.05) and prothrombin time (PT) ( HR =1.282, 95% CI : 1.080-1.630, P < 0.05) were independent risk factors for PFS, and aspartate aminotransferase level ( HR =1.008, 95% CI : 1.002-1.013, P < 0.05) and PT ( HR =1.303, 95% CI : 1.046-1.630, P < 0.05) were independent risk factors for OS. Conclusion FOLFOX-HAIC and its multimodality therapeutic regimen has a certain clinical effect with controllable adverse reactions in the treatment of advanced hepatocellular carcinoma.

Objective:To explore the relationship between input and output of occupational health funds, and to provide basis for relevant departments to make decisions.Methods:In September 2018, a state-owned iron ore in Hebei Province (mining history of more than 10 years, which can represent the general type of iron ore) was selected as the research object. Through the investigation and collection of enterprise general situation, occupational health input, loss and output related indicators, the iron mine occupational health expenditure input-output table and model were established, and the digital relationship between the investment and output was solved by MATLAB software.Results:The labor consumption in the departments of underground mining, open pit mining, crushing and rock discharging, transportation, tailings and mineral processing (taking labor wages as reference) were 756.46, 1.281.78, 987.61, 1 570.71, 50.956 and 18.9116 million yuan/year respectively. The output value of each sector is 11 207.19, 18 989.95, 15 176.40, 25 294.00, 7.704.94 and 280.1797 million yuan/year respectively. The ratio of health input to total output was 0.004 5, and the ratio of occupational health input to output was 1/0.046.Conclusion:The input-output table model of occupational health in iron mine can reflect the relationship between input and output of occupational health funds. The input situation of the coal mine is poor, and the input does not bring obvious occupational health benefits.
