The general models for intermediates quality analysis in the production process of Yaobitong capsule were established by near infrared spectroscopy (NIRS) combined with chemometrics, realizing the rapid determination of notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rd and moisture. The spray-dried fine powder and total mixed granule were selected as research objects. The contents of five saponins were determined by high performance liquid chromatography and the moisture content was determined by drying method. The measured contents were used as reference values. Meanwhile, NIR spectra were collected. After removing abnormal samples by Monte Carlo cross validation (MCCV), Monte Carlo uninformative variables elimination (MC-UVE) and competitive adaptive reweighted sampling (CARS) were used to select feature variables respectively. Based on the feature variables, quantitative models were established by partial least squares regression (PLSR), extreme learning machine (ELM) and ant lion optimization least squares support vector machine (ALO-LSSVM). The results showed that CARS-ALO-LSSVM model had the optimum effect. The correlation coefficients of the six index components were greater than 0.93, and the relative standard errors were controlled within 6%. ALO-LSSVM was more suitable for a large number of samples with rich information, and the prediction effect and stability of the model were significantly improved. The general models with good predicting effect can be used for the rapid quality determination of Yaobitong capsule intermediates.

OBJECTIVE To investigate the effects of Tongxie yaofang （TXYF） on the symptoms of rats with irritable bowel syndrome with diarrhea （IBS-D） by regulating colonic tryptophan hydroxylase 1 （TPH1）， serotonin transporter （SERT） and intestinal flora. METHODS Forty-two SD rats were randomly divided into control group （7 rats） and modeling group （35 rats）. In modeling group， rat model of IBS-D was established by intragastrical administration of 0.45 g/L senna leaf solution [10 mL/（kg·d）] combined with chronic unpredictable stimulation. Thirty-five successfully modeled rats were randomly divided into model group， pinaverium bromide group [15 mg/（kg·d）] and TXYF low-dose， medium-dose and high-dose groups [3.75、7.5、15 g/（kg·d）， calculated by crude drug]， with 7 rats in each group. Each administration group was orally administered the corresponding drug， once a day， for 10 consecutive days. The general condition and weight changes of each group of rats were compared before modeling， after modeling and before administration， after the last drug intervention； the diarrhea index and visceral sensitivity were detected， and pathological changes of colon tissue were observed after modeling and before administration， after the last drug intervention. The level and expression of 5-hydroxytryptamine （5-HT）， protein and mRNA expressions of TPH1 and SERT were determined in colon tissue. The diversity and structural changes of fecal intestinal flora of rats were analyzed. RESULTS There was no significant change in colon histopathology in each group. Compared with model group， the general condition of rats in each medication group improved. The daily body weight gain of rats was significantly increased， while diarrhea index， visceral sensitivity， the expressions of 5-HT and TPH1 in colon tissue were significantly decreased； SERT expression of colon tissue was significantly increased in TXYF medium-dose and high-dose groups （P＜0.05 or P＜0.01）. The diarrhea index， colon TPH1 protein expression and colon 5-HT protein positive rate in the TXYF low-dose group decreased while the mRNA expression of SERT increased significantly （P＜0.05）. There was a dose- dependent trend in the effect of TXYF. Compared with model group， Chao1 index and Shannon index of the rats in TXYF high- dose group were significantly decreased （P＜0.05 or P＜0.01）， the beneficial bacteria such as Firmicutes and Lactobacillus increased significantly， while the pathogenic bacteria such as Proteobacteria， Escherichia-Shigella and Rikenellaceae_RC9_gut_ group decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS TXYF can decrease the level of 5-HT and improve intestinal flora disorder by inhibiting the expression of TPH1 and up-regulating the expression of SERT in colon tissue， thus promoting the symptoms of IBS-D rats.

Veno-arterial extracorporeal membrane oxygenation is an effective method to reduce perioperative adverse events such as cardiogenic shock in patients undergoing complex high-risk indicated percutaneous coronary intervention.Femoral artery and femoral vein are the main routes for conventional veno-arterial extracorporeal membrane oxygenation in China,while the cases of extracorporeal membrane oxygenation insertion via axillary artery are relatively rare.However,the axillary artery intubation veno-arterial extracorporeal membrane oxygenation assisted mode has been regarded as one of the routine clinical paths for the treatment of critically ill patients in foreign countries.This paper reports a case of an elderly male patient who underwent high risk and complex percutaneous coronary interventional therapy by right axillary artery implantation with extracorporeal membrane oxygenation assisted circulation due to the difficulty of femoral artery approach.In order to provide reference for the selection of clinical extracorporeal membrane oxygenation technique route.

Ulcerative colitis (UC) is a chronic inflammation of the gastrointestinal tract and is characterized by alternating periods of inflammation and remission. Although UC incidence is lower in Taiwan than in Western countries, its impact remains considerable, demanding updated guidelines for addressing local healthcare challenges and patient needs. The revised guidelines employ international standards and recent research, emphasizing practical implementation within the Taiwanese healthcare system. Since the inception of the guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease has acknowledged the need for ongoing revisions to incorporate emerging therapeutic options and evolving disease management practices. This updated guideline aims to align UC management with local contexts, ensuring comprehensive and context-specific recommendations, thereby raising the standard of care for UC patients in Taiwan. By adapting and optimizing international protocols for local relevance, these efforts seek to enhance health outcomes for patients with UC.

Crohn’s disease (CD) is a chronic, fluctuating inflammatory condition that primarily affects the gastrointestinal tract. Although the incidence of CD in Taiwan is lower than that in Western countries, the severity of CD presentation appears to be similar between Asia and the West. This observation indicates the urgency for devising revised guidelines tailored to the unique reimbursement system, and patient requirements in Taiwan. The core objectives of these updated guidelines include the updated treatment choices and the integration of the treat-to-target strategy into CD management, promoting the achievement of deep remission to mitigate complications and enhance the overall quality of life. Given the diversity in disease prevalence, severity, insurance policies, and access to medical treatments in Taiwan, a customized approach is imperative for formulating these guidelines. Such tailored strategies ensure that international standards are not only adapted but also optimized to local contexts. Since the inception of its initial guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease (TSIBD) has acknowledged the importance of continuous revisions for incorporating new therapeutic options and evolving disease management practices. The latest update leverages international standards and recent research findings focused on practical implementation within the Taiwanese healthcare system.

BACKGROUND: Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations. METHODS: In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively. RESULTS: 81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count. CONCLUSIONS In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

OBJECTIVE: To evaluate toxicity of raw extract of Panax notoginseng (rPN) and decocted extract of PN (dPN) by a toxicological assay using zebrafish larvae, and explore the mechanism by RNA sequencing assay. METHODS: Zebrafish larvae was used to evaluate acute toxicity of PN in two forms: rPN and dPN. Three doses (0.5, 1.5, and 5.0 µ g/mL) of dPN were used to treat zebrafishes for evaluating the developmental toxicity. Behavior abnormalities, body weight, body length and number of vertebral roots were used as specific phenotypic endpoints. RNA sequencing (RNA-seq) assay was applied to clarify the mechanism of acute toxicity, followed by real time PCR (qPCR) for verification. High performance liquid chromatography analysis was performed to determine the chemoprofile of this herb. RESULTS: The acute toxicity result showed that rPN exerted higher acute toxicity than dPN in inducing death of larval zebrafishes (P<0.01). After daily oral intake for 21 days, dPN at doses of 0.5, 1.5 and 5.0 µ g/mL decreased the body weight, body length, and vertebral number of larval zebrafishes, indicating developmental toxicity of dPN. No other adverse outcome was observed during the experimental period. RNA-seq data revealed 38 genes differentially expressed in dPN-treated zebrafishes, of which carboxypeptidase A1 (cpa1) and opioid growth factor receptor-like 2 (ogfrl2) were identified as functional genes in regulating body development of zebrafishes. qPCR data showed that dPN significantly down-regulated the mRNA expressions of cpa1 and ogfrl2 (both P<0.01), verifying cpa1 and ogfrl2 as target genes for dPN. CONCLUSION This report uncovers the developmental toxicity of dPN, suggesting potential risk of its clinical application in children.

OBJECTIVE: To explore the effect of dichloromethane extraction phase of ethanol extract from stem of Patrinia scabiosaefolia Fisch.(DPSS) on proliferation and differentiation of K562 cells and its related mechanism. METHODS: MTT assay was used to detect the effects of DPSS at 0, 25, 50, 100 and 200 μg/ml on the proliferation of K562 cells at 24, 48 and 72 hours. Flow cytometry was used to analyze the changes of cell cycle and apoptosis at 24 and 48 hours. Wright-Giemsa staining was used to observe the morphological changes of K562 cells. The cell surface antigens CD33 and CD11b were detected by flow cytometry. RESULTS: The proliferation of K562 cells treated with different concentrations of DPSS was inhibited in a time-dose dependent manner (r=-0.96). Cell cycle analysis showed that with the increase of DPSS concentration, cells in G₂/M phase increased (r=0.88), and cells were blocked in G₂/M phase. Flow cytometry results showed that with the apoptosis rate of K562 cells was the highest when treated with 200 μg/ml DPSS for 48 h. Morphological observation showed that the K562 cell body increased, the amount of cytoplasm increased, the ratio of nucleus to cytoplasm decreased, and the nuclear chromatin was rough after DPSS treatment. Cell differentiation antigen, CD33 and CD11b, were positively expressed after treated with DPSS. CONCLUSION DPSS can induce apoptosis through cell cycle arrest, inhibit the proliferation of K562 cells, and induce K562 cells to differentiate into monocytes, which has a potential anti-leukemia effect.

ObjectiveTo explore the co-expression of PTBP1 and p-AXL in osteosarcoma and its clinicopathological significance for prognosis evaluation. MethodsThe expression of PTBP1 and AXL and their prognostic value in osteosarcoma were analyzed by GEO and Target data. Paraffin biopsy specimens and clinical information from 76 cases of osteosarcoma and 37 cases of non-malignant bone tissue （callus， osteofibrous dysplasia and osteoid ostema） were obtained from the First Affiliated Hospital of Sun Yat-sen University from March 2016 to October 2020. The expressions of PTBP1 and p-AXL proteins in osteosarcoma were detected by immunohistochemistry. ResultsGEO database showed that the expression levels of PTBP and AXL in osteosarcoma tumor group were higher than those in normal tissues， but did not reach statistical significance. Target database showed that the high expression of PTBP1 had shorter Overall survival（OS） and Progression-free survival（PFS） than low PTBP1 expression， but did not reach statistical significance （P=0.064； P=0.134）. Immunohistochemical staining included 76 cases of osteosarcoma and 37 cases of non-malignant bone tissue. The expression rate of PTBP1 and p-AXL protein in osteosarcoma tissues was higher than that in non-malignant bone tissue. The expression of p-AXL is correlated with lung metastasis （P=0.025）. Kaplan-Meier analysis showed that lung metastasis， recurrence， PTBP1 expression， co-expression of PTBP1/p-AXL influence the prognosis of patients in OS. Multivariate Cox regression analysis showed that lung metastasis （P<0.000 1） and positive expression of PTBP1 （P=0.041） were independent risk factors for osteosarcoma patients in OS. Co-expression of PTBP1 and p-AXL had shorter OS （P=0.017） and PFS （P=0.043） than non-coexpression osteosarcoma patients. ConclusionsPTBP1 and p-AXL were highly expressed in osteosarcoma tissues. The co-expression of PTBP1 and p-AXL was associated with poor prognosis of patients， and PTBP1 could be used as an independent prognostic indicator of patients with osteosarcoma.
