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.

Parkinson's disease (PD) is the most common neurodegenerative movement disease. It is featured by abnormal alpha-synuclein (α-syn) aggregation in dopaminergic neurons in the substantia nigra. Macroautophagy (autophagy) is an evolutionarily conserved cellular process for degradation of cellular contents, including protein aggregates, to maintain cellular homeostasis. Corynoxine B (Cory B), a natural alkaloid isolated from Uncaria rhynchophylla (Miq.) Jacks., has been reported to promote the clearance of α-syn in cell models by inducing autophagy. However, the molecular mechanism by which Cory B induces autophagy is not known, and the α-syn-lowering activity of Cory B has not been verified in animal models. Here, we report that Cory B enhanced the activity of Beclin 1/VPS34 complex and increased autophagy by promoting the interaction between Beclin 1 and HMGB1/2. Depletion of HMGB1/2 impaired Cory B-induced autophagy. We showed for the first time that, similar to HMGB1, HMGB2 is also required for autophagy and depletion of HMGB2 decreased autophagy levels and phosphatidylinositol 3-kinase III activity both under basal and stimulated conditions. By applying cellular thermal shift assay, surface plasmon resonance, and molecular docking, we confirmed that Cory B directly binds to HMGB1/2 near the C106 site. Furthermore, in vivo studies with a wild-type α-syn transgenic drosophila model of PD and an A53T α-syn transgenic mouse model of PD, Cory B enhanced autophagy, promoted α-syn clearance and improved behavioral abnormalities. Taken together, the results of this study reveal that Cory B enhances phosphatidylinositol 3-kinase III activity/autophagy by binding to HMGB1/2 and that this enhancement is neuroprotective against PD.

Objective:To observe the effect of Yuxuebi tablets on hyperalgesia and foot swelling in mice with chronic inflammatory pain， and to explore the preliminary mechanism of action. Method:A mouse model of chronic inflammatory pain was established with left plantar injection of complete Freund's adjuvant （CFA）. The mice were divided into model group， positive drug ibuprofen group （91 mg·kg^-1）， Yuxuebi tablets low， medium and high dose groups （55， 110， 220 mg·kg^-1），with the sham operation group as the control. After successful modeling， the daily dose was divided into two doses in the morning and evening by gavage to give Yuxuebi tablets or ibuprofen to the stomach for a total of 19 days. On the 18^th day after the administration， the thermal pain threshold was detected by the hot plate method. On the 19^th day， the standard Von Frey fiber needle was used to detect the mechanical pain threshold of the mice， and the degree of foot swelling was scored and photographed. The liquid-phase suspension chip technology was used to quantitatively analyze 36 classic broad-spectrum inflammation-related factors like inflammatory factors and receptors. Bioinformatics were used to screen core targets and perform enzymelinked immunosorbent assay （ELISA） detection. Result:Compared with the sham operation group， the mechanical pain threshold and foot swelling score of the model froup significantly increased （P<0.01）， the latent time of heat sensitivity significantly decreased（P<0.01）， the expressions of 30 inflammatory factors in the foot increased（P<0.05）. Compared with the model group， the high dose of Yuxuebi tablets significantly reduced the mechanical pain threshold and foot swelling score of mice with chronic inflammatory pain（P<0.01）， significantly increased the latent time of heat sensitivity（P<0.05）， and reduced the expressions of 30 inflammatory factors in the foot（P<0.05）， among which tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， interleukin-17A （IL-17A）， and C-C chemokine ligand 2 （CCL2） were the core targets screened out， and the expressions of TNF-α， IL-17A， and CCL2 significantly decreased （P<0.01）. Conclusion:Yuxuebi tablets can relieve hyperalgesia and foot swelling in mice with chronic inflammatory pain， and its mechanism may be related to the inhibition of the expressions of peripheral inflammatory factors such as TNF-α， IL-17A， and CCL2 .

Objective:To analyze the clinical characteristics of infantile Takayasu arteritis and the efficacy of infliximab (IFX).Methods:Clinical manifestations, laboratory investigations and infliximab intervention of a case with infantile Takayasu arteritis, who was admitted to Department of Rheumatism and Immunology, Children′s Hospital, Capital Institute of Pediatrics in January 2018, were reviewed and analyzed. The related literature published from the beginning to March 2020 were retrieved from CNKI, Wanfang, SinoMed and PubMed with the keywords of"Takayasu arteritis","Infant" in both Chinese and English.Results:This case was a 70-day-old boy admitted due to recurrent fever for 20 days. On admission, his blood pressure were 104/90, 95/59, 125/80, and 152/125 mmHg (1 mmHg=0.133 kPa) in the right arm, left arm, right leg, and left leg, respectively. The complete blood cell count showed leukocytosis (22.6×10 9/L), thrombocytosis (858×10 9/L) and mild anemia (80 g/L). He also had elevated erythrocyte sedimentation rate (119 mm/1h), serum ferritin (598 μg/L) and C-reactive protein (112 mg/L). Computed tomographic angiography (CTA) showed narrowing of the thoracic and abdominal aorta, with thickening and heterogenous enhancement of the vessel wall. Coronary artery ultrasound detected dilatation and wall thickening of the bilateral coronary arteries, and uneven dilatation of the middle segment of the right coronary artery, showing bead-like change. Vessel wall thickening was also found in the other main arteries, including both femoral arteries, axillary arteries, carotid arteries, and subclavian arteries, and both superficial femoral arteries were slightly narrowed in the distal segments. The diagnosis of TA was confirmed, and the boy was treated with infliximab monotherapy (5 mg/(kg·every time), a total of 13 times). Then his body temperature and all inflammatory markers were normalized, and the vascular pathology was resolved according to the radiography. No side effects such as allergy or infection were noted during the treatment. During the 2 years and 6 months of follow-up, the boy maintained normal growth and development. Literature review found 8 related articles, and one of them was in Chinese but had limited information. In the other 7 papers, a total of 7 infants with TA were reported. The most common symptom was fever (5 cases), and inflammatory markers usually elevated, and the most common affected artery was abdominal aorta (6 cases). Most cases were treated with glucocorticoid. Conclusions:TA is a rare disease in infants, usually presents with fever and increased inflammatory markers. At the early stage, infliximab monotherapy could effectively control the symptoms and ensure normal growth and development.

Objective To evaluate the application of 43-plex SNP typing system in forensic science. Methods The typing of 43 SNP loci in 123 unrelated Han individuals from East China was detected by MALDI-TOF-MS. The application value of 43-plex SNP typing system was assessed according to the foren-sic parameters of population genetics. Results All the 43 SNP loci of 123 individuals showed no signifi-cant departure from Hardy-Weinberg equilibrium (P>0.05). Excepted rs1355366, rs2270529, rs10776839 and rs938283, there were 39 SNP loci had minor allele frequencies (MAF), which were greater than 0.25. Among the 25 loci MAFs, 24 ranged from 0.4 to 0.5, while 3 were close to 0.4. The DP, CDP, PIC, Ho, PEtrio and PEduo of the 43 SNP loci were 0.2901-0.6544, 1-9.8×10-11, 0.1708-0.5000, 0.1557-0.5935, 0.0854-0.2500 and 0.0146-0.1250, respectively. The CPEtrio and CPEduo were 0.999986 and 0.9924361, respectively. Conclusion The 43-plex SNP typing system in present study shows a high polymorphism, which can be an effective supplement and verification for traditional STR genetic markers. It also can be used with other commercial kits for the forensic paternity testing and individual identification.

To establish the fingerprints of Xiasangju granules (with sugar and non-sugar forms) by HPLC, and provide reference for their identification and effective quality control. High performance liquid chromatography (HPLC) method was used to collect the fingerprints of 20 batches of non-sugar Xiasangju granules and 34 batches of sugar type Xiasangju granules. Their main different components were classified and screened by mode identification methods (principal component analysis, PCA, and orthogonal partial least squares discriminate analysis, OPLS-DA). The principal components were identified by comparing with reference standards. The fingerprints of Xiasangju granules (sugar type and non-sugar type) were established. PCA could not fully classify the two types of granules, while OPLS-DA could obviously classify these two different types of Xiasangju granules. Six components showed greatest difference between two types of granules, including salviaflaside, luteoloside and linarin. The developed mode identification method is helpful to control the overall quality of Xiasangju granules, and it provides an effective approach to quality evaluation.
