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.

The peeled stems of Syringa pinnatifolia(SP) is a representative Mongolian folk medicine with the effects of anti-depression, heat clearance, pain relief, and respiration improvement. It has been clinically used for the treatment of coronary heart disease, insomnia, asthma, and other cardiopulmonary diseases. As part of the systematic study on pharmacological substances of SP, 11 new sesquiterpenoids were isolated from the terpene-containing fractions of the ethanol extract of SP by liquid chromatography-mass spectrometry(LC-MS) and proton nuclear magnetic resonance(~1H-NMR) guided isolation methods. The planar structures of the sesquiterpenoids were identified by MS, 1D NMR, and 2D NMR data analysis, and were named pinnatanoids C and D(1 and 2), and alashanoids T-ZI(3-11), respectively. The structure types of the sesquiterpenoids included pinnatane, humulane, seco-humulane, guaiane, carryophyllane, seco-erimolphane, isodaucane, and other types. However, limited to the low content of compounds, the existence of multiple chiral centers, the flexibility of the structure, or lack of ultraviolet absorption, the stereoscopic configuration remained unresolved. The discovery of various sesquiterpenoids enriches the understanding of the chemical composition of the genus and species and provides references for further analysis of pharmacological substances of SP.

OBJECTIVE: To investigate the clinical characteristics and risk factors of cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with severe aplastic anemia (SAA). METHODS: Clinical data from 270 SAA patients with allo-HSCT were retrospectively analyzed, including 108 sib congruence patients and 162 substitute donors (68 unrelated donor congruence patients and 94 related haploid patients). Different pretreatment schemes were selected for different transplantation modes. The HLA-identical sibling and haploid grafts were all bone marrow and peripheral blood stem cells, and the grafts from unrelated donors were peripheral blood stem cells. After granulocyte implantation, blood CMV-DNA was regularly monitored. Flow cytometry was also used to determine the absolute number of CD3 RESULTS: CMV infection occurred in 229 of 270 patients with an incidence of 84.8%. Among them, 18 patients developed giant cell disease. Univariate analysis showed that alternative donors (unrelated total and haploid donors), mycophenolate mofetil and acute graft-versus-host disease were statistically significantly associated with CMV infection (P<0.05). Multivariate analysis showed that alternative donors were associated with CMV infection. The recovery of CD3 CONCLUSION After allo-HSCT, substitute donors are more easily to develop CMV infection than full-sibling donors, and the reconstruction of immune function is delayed after transplantation.

Modern research has confirmed a wide range of pharmacological activities, such as regulating blood sugar, improving gastrointestinal inflammation, and regulating immunity. Polysaccharides are the main active ingredients of D. officinale. With the intensive studies of the pharmacological activities of D. officinale, evidence for the pharmacological effects and potential mechanisms of D. officinale polysaccharides has increased dramatically. In this review, we summarized the latest progress in the pharmacological and mechanical studies of D. officinale polysaccharides, and based on the pharmacological efficacy and oral absorption and utilization characteristics of D. officinale polysaccharides, it is proposed that regulating the gut microbiota may be one of the key mechanisms for D. officinale to exert its beneficial effects. Research on the mechanism of D. officinale polysaccharides puts forward new research directions and prospects.

As an important substitute for agarwood, mountain-agarwood, belonging to the family Oleaceae, comes from the root, stem and thick branch of Syringa pinnatifolia, which has a wide range of application in Inner Mongolia, China. It has good clinical efficacy in the use of cardiovascular diseases. However, the formation speed of mountain-agarwood is extremely slow, and its cultivated seedlings have low resin content. Therefore, how to speed up the formation of mountain-agarwood and increase the resin content is a hot research topic in this field. In this work, 16 S rDNA amplicon sequencing method was used to systematically analyze the bacterial communities of different samples of mountain-agarwood. Our data revealed that the samples of mountain-agarwood had more obvious species diversity than the ones of non-mountain-agarwood, especially the wild mountain-agarwood samples. By analysis of bacterial community composition and species abundance, Sphingomonas, Modestobacter and unidentified Cyanobacteria genus were three dominant bacterial genera in all samples. In addition, there are two identified genera of dominant bacteria, namely Actinoplanes and Microbacterium in both wild and cultivated mountain-agarwood, by bacterial community composition and species richness analysis. Meanwhile, Roseomonas was the dominant bacterial genus in both wild and cultivated non-mountain-agarwood samples. Our work could provides basic data for exploring the mechanism of the mountain-agarwood formation, and help to exploit resource of endophytic bacteria reasonably.

Syringa pinnatifolia Hemsl.( SP) is a representative Mongolian folk medicine with the effects of inhibiting Heyi related diseases,clearing heat and relieving pain. It has been used for the treatment of Heyi-induced heart tingling,heart palpitations,upset,insomnia and other symptoms. Total ethanol extract( T) and major fraction( M) of SP have been evaluated its anti-ischemic effects,and the mechanism was related to the regulation of cyclooxygenase( COX)-mediated inflammatory pathway and p53-mediated apoptosis pathway in our previous studies. This study reports the chemical fractionation on M by which to obtain subfractions( I and M_3),and the pharmacological evaluation of M,I,and M_3 against myocardial ischemia in mice. The result showed that I and M reduced the values of LVEDd and LVEDs,significantly increased EF and FS values,increased serum CK-MB and LDH levels in mice,and reduced in inflammatory cells infiltration and collagen deposition in the infarcted myocardial tissue,suggesting that M and I possess the same degree anti-myocardial is chemia equally whereas M_3 has no this effect. Related mechanism studies suggested that I can reduce the expression of COX-1,COX-2 and p53 protein in myocardial tissue in a dose-dependent manner. This study lays the foundation for further chemical segmentation and clarification of pharmacological substance groups,paving the way for the full use and benefits to be use of systematic biological methods to analyze the pharmacological basis of SP against myocardial ischemia.

AIM: To investigate the effect of tumor necrosis factor receptor associated factor 6 (TRAF6) on proliferation, apoptosis and invasion of retinoblastoma Y79 cells. METHODS: The Y79 cells were divided into three groups:blank control group, negative control group and TRAF6 siRNA group. After TRAF6 siRNA transfection, the levels of TRAF6 mRNA and protein in Y79 cells were examined by RT-PCR and Western blotting. MTT assay was used to detect cell proliferation. Flow cytometry was employed to detect changes in cell cycle and apoptosis. Cell invasiveness was detected by the Transwell method. RESULTS: Expression of TRAF6 mRNA and protein in the TRAF6 siRNA group significantly decreased compared with the negative and blank control groups. Following the silencing of TRAF6,cell proliferation was inhibited and the apoptosis rate increased; the cell cycle was arrested at G0/G1 phase; the number of cells in S phase was reduced, while the invasion ability of cancer cells decreased. CONCLUSION: Silencing TRAF6 may inhibit the proliferation of Y79 cells, promote cell apoptosis, arrest the cell cycle at G0/G1 phase and decrease the invasive ability. Thus,TRAF6 may be a potential target in therapy for retinoblastoma.
