Phakic intraocular lens implantation has become one of the important means of correcting refractive errors today. Among them,the implantable collamer lens(ICL)is favored for its wide range of correction, excellent optical quality, and high safety, but the risks of postoperative complications such as glaucoma and anterior subcapsular opacification still exist. Vault is an important indicator for evaluating the safety after ICL implantation, and its ideal state is crucial for preventing complications. Studies have shown that iris morphology has a significant impact on vault. In order to further optimize surgical outcomes and improve surgical safety, this review comprehensively reviews the research progress of iris-related parameters in ICL implantation and discusses the importance of various parameters in preoperative evaluation and postoperative follow-up.

ObjectiveTo investigate the effect of mucin 1 (MUC1) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) and its regulatory mechanism. MethodsThe 60 NPC and paired para-cancer normal tissues were collected from October 2020 to July 2021 in Quanzhou First Hospital. The expression of MUC1 was measured by real-time quantitative PCR (qPCR) in the patients with PNC. The 5-8F and HNE1 cells were transfected with siRNA control (si-control) or siRNA targeting MUC1 (si-MUC1). Cell proliferation was analyzed by cell counting kit-8 and colony formation assay, and apoptosis was analyzed by flow cytometry analysis in the 5-8F and HNE1 cells. The qPCR and ELISA were executed to analyze the levels of TNF-α and IL-6. Western blot was performed to measure the expression of MUC1, NF-кB and apoptosis-related proteins (Bax and Bcl-2). ResultsThe expression of MUC1 was up-regulated in the NPC tissues, and NPC patients with the high MUC1 expression were inclined to EBV infection, growth and metastasis of NPC. Loss of MUC1 restrained malignant features, including the proliferation and apoptosis, downregulated the expression of p-IкB、p-P65 and Bcl-2 and upregulated the expression of Bax in the NPC cells. ConclusionDownregulation of MUC1 restrained biological characteristics of malignancy, including cell proliferation and apoptosis, by inactivating NF-κB signaling pathway in NPC.

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.

As arsenic widely exists in nature and has been used in the pharmaceutical preparations, the traditional Chinese medicine(TCM) with arsenic include realgar(As_2S_2 or As_4S_4), orpiment(As_2S_3), and white arsenic(As_2O_3). Among the above representative medicine, the TCM compound formulas with realgar are utilized extensively. Just in Chinese Pharmacopoeia(2020 edition), there are 37 Chinese patent medicines including realgar. The traditional element analysis focuses on the detection of the total amount of elements, which neglects the study on the speciation and valence of elements. The activity, toxicity, bioavailability, and metabolic pathways of arsenic in vivo are closely related to the existence of its form, and different forms of arsenic have different effects on organisms. Therefore, the study on the speciation and valence of arsenic is of great importance for arsenic-containing TCMs and their compound formulas. This paper reviewed four aspects of the speciation and valence of arsenic, including property, absorption and metabolism, toxicity, and analytical assay.

Objective: To analyze the risk factors for complications of endoscopic full-thickness resection (EFTR) of upper gastrointestinal submucosal tumors (SMTs). Methods: This was a retrospective observational study. The indications for EFTR included: (1) SMTs originating from the muscularis propria layer and growing out of the cavity or infiltrating the deep part of the muscularis propria layer; (2) SMTs diameter <5 cm; and (3) tumor identified as closely adherent to the serous layer during endoscopic submucosal dissection or endoscopic mucosal resection. This study included patients with SMTs originating from the muscularis propria layer in upper digestive tract, diagnosed preoperatively by endoscopic ultrasonography or computed tomography, who were successfully treated with EFTR. Those with incomplete clinical data were excluded. The clinical data of 154 patients with upper gastrointestinal SMTs who underwent EFTR at the Department of Gastroenterology, First Affiliated Hospital of Soochow University from January 2016 to January 2022 were retrospectively analyzed. Post-EFTR complications (such as delayed perforation, delayed bleeding, and postoperative infection, including electrocoagulation syndrome) were monitored and the risk factors for them were analyzed. Results: Among the 154 study patients, 33 (21.4%) developed complications, including delayed bleeding in three (1.9%), delayed perforation in two (1.3%), and postoperative infection in 28 (18.2%). One patient with bleeding was classified as having a major complication (hospitalized for more than 10 days because of complication). According to univariate analysis, complication was associated with tumor diameter >15 mm, operation time >90 minutes, defect closure method(purse string suture), and diameter of resected specimen ≥20 mm (all P<0.05). Multivariate logistic regression analysis showed that operation time >90 minutes (OR=6.252, 95%CI: 2.530-15.446, P<0.001) and tumor diameter >15 mm (OR=4.843, 95%CI: 1.985-11.817, P=0.001) were independent risk factors for complications after EFTR in patients with upper gastrointestinal SMTs. The independent risk factors for postoperative infection in these patients were operation time>90 minutes (OR=4.993, 95%CI:1.964-12.694, P=0.001) and purse string suture (OR=7.142, 95%CI: 1.953-26.123, P=0.003). Conclusion: Patients with upper gastrointestinal SMTs undergoing EFTR with tumor diameter >15 mm or operation time >90 minutes have a significantly increased risk of postoperative complications. Postoperative monitoring is important for these patients with SMTs.

Near-infrared spectroscopy(NIRS) combined with band screening method and modeling algorithm can be used to achieve the rapid and non-destructive detection of the traditional Chinese medicine(TCM) production process. This paper focused on the ginkgo leaf macroporous resin purification process, which is the key technology of Yinshen Tongluo Capsules, in order to achieve the rapid determination of quercetin, kaempferol and isorhamnetin in effluent. The abnormal spectrum was eliminated by Mahalanobis distance algorithm, and the data set was divided by the sample set partitioning method based on joint X-Y distances(SPXY). The key information bands were selected by synergy interval partial least squares(siPLS); based on that, competitive adaptive reweighted sampling(CARS), successive projections algorithm(SPA) and Monte Carlo uninformative variable(MC-UVE) were used to select wavelengths to obtain less but more critical variable data. With selected key variables as input, the quantitative analysis model was established by genetic algorithm joint extreme learning machine(GA-ELM) algorithm. The performance of the model was compared with that of partial least squares regression(PLSR). The results showed that the combination with siPLS-CARS-GA-ELM could achieve the optimal model performance with the minimum number of variables. The calibration set correlation coefficient R_c and the validation set correlation coefficient R_p of quercetin, kaempferol and isorhamnetin were all above 0.98. The root mean square error of calibration(RMSEC), the root mean square error of prediction(RMSEP) and the relative standard errors of prediction(RSEP) were 0.030 0, 0.029 2 and 8.88%, 0.041 4, 0.034 8 and 8.46%, 0.029 3, 0.027 1 and 10.10%, respectively. Compared with the PLSR me-thod, the performance of the GA-ELM model was greatly improved, which proved that NIRS combined with GA-ELM method has a great potential for rapid determination of effective components of TCM.
