Objective Orosomucoid1 (ORM1) is a novel target in the quest for anti-fatigue pharmacotherapy. Preliminary investigations have illuminated oleuropein (OLE) as a promising candidate molecule, poised to enhance ORM1 expression. To elucidate the influence of OLE on ORM1 protein expression and assess its ramifications on muscle endurance. Methods The impact of OLE on ORM1 protein expressions within hepatocytes and liver tissue was meticulously quantified through Western blotting; the effects of OLE on muscle endurance were evaluated via the rotarod and forced swimming tests; glycogen content within liver and muscle tissues was determined utilizing a specialized kit; and PAS staining was employed to visualize glycogen deposition in the gastrocnemius muscle. Results OLE demonstrated a capacity to elevate ORM1 protein expression in hepatocytes in a time- and dose-dependent manner, concurrently prolonging the duration of swimming and rotarod performance in mice, also in a time- and dose-dependent manner. Furthermore, OLE augmented ORM1 expression in liver tissue, elevated serum ORM1 levels, and enhanced glycogen reserves within the liver and muscle. Conclusion OLE may serve to amplify muscle endurance by elevating ORM1 levels in vivo and augmenting glycogen stores within skeletal muscle.

To investigate the positivity rates of specific antibodies, including parietal cell antibody (PCA) and anti-inner factor antibody (IFA), in a community population in Xinjiang for autoimmune gastritis (AIG), determine the prevalence of AIG, and analyze the correlations of PCA and IFA with clinical characteristics, pepsinogen (PG), gastrin 17 (G17), and A cross-sectional survey was conducted using stratified random cluster sampling in community populations across 10 regions of Xinjiang from January 2022 to December 2023. General information was collected via a self-designed questionnaire, and fasting venous blood samples were obtained to measure laboratory parameters including PCA, IFA, PG Ⅰ, PG Ⅱ, PG Ⅰ/PG Ⅱ ratio, and G17. The positivity rates of PCA and IFA and the prevalence of AIG were calculated. Spearman correlation analysis was used to assess the relationships of PCA and IFA with PG Ⅰ, PG Ⅱ, PG Ⅰ/PG Ⅱ ratio, and G17. The diagnostic efficacy of PCA and IFA for atrophic gastritis was evaluated using receiver operating characteristic (ROC) curves, and multivariate logistic regression analysis was performed to identify factors influencing PCA and IFA positivity. A total of 2018 community participants were included, comprising 972 males (48.17%) and 1046 females (51.83%), with a mean age of 42±19 years. The predominant ethnic groups were Han (42.22%) and Kazakh (33.10%). Hp-Ab positivity was observed in 1244 cases (61.65%). Serological criteria for atrophic gastritis were met in 56 cases (2.78%). PCA positivity was found in 253 cases (12.54%), IFA positivity in 30 cases (1.49%), and dual positivity in 11 cases (0.55%). A total of 617 participants (30.57%) voluntarily underwent endoscopic examination, among whom 7 cases (1.13%) were histopathologically confirmed as AIG. Positivity rates for PCA and IFA varied among ethnic groups, with the highest rates observed in the Kirgiz population (23.53% and 5.88%, respectively). Spearman correlation analysis revealed that PCA was negatively correlated with the PG Ⅰ/PG Ⅱ ratio ( The positivity rate of PCA is relatively high in the community population in Xinjiang and varies across different ethnic groups, whereas the positivity rate of IFA is lower than that of PCA. Age, history of alcohol consumption, history of allergies, and history of thyroid disease are associated with PCA positivity, while no correlation was found between Hp-Ab and PCA or IFA. The prevalence of histopathologically confirmed AIG among participants undergoing endoscopic examination is 1.13%.

Objective:To understand the current status and characteristics of clinical trials for oral diseases in China, for the purpose of providing a reference for the research and development of oral diseases in China.Methods:Retrieving the information on clinical trials related to oral diseases registered on the "Platforms for drug clinical trial registration and information" of the National Medical Products Administration from the date of the database establishment to December 31, 2024. The number of clinical trials, type of drugs, trial phases, indication, trial scope, design types were statistically analyzed.Results:As of December 31, 2024, a total of 578 drug clinical trials for oral disease were registered, accounting for 2.1% (578/27 905) of the clinical trials disclosed on the platform during the same period. Bioequivalence clinical trials accounted for the highest proportion [73.9% (427/578)], followed by Phase Ⅰ [9.0% (52/578)], Phase Ⅱ [8.0% (46/578)], and Phase Ⅲ [4.5% (26/578)]. The 578 clinical trials involved 149 types of trial drugs, mainly chemical drugs, among which 127 were developed by domestic pharmaceutical enterprises and 27 by international pharmaceutical enterprises (the five investigational drugs have undergone clinical trials by both domestic and international pharmaceutical companies). The project leader units of the 578 drug clinical trials were distributed in 27 provinces, autonomous regions, municipalities, and Hong Kong Special Administrative Region. Excluding 427 bioequivalence clinical trials, the project leader units of 151 new drug clinical trials showed a significant aggregation phenomenon, and only three specialized oral hospitals have served as project leader units for drug clinical trials.Conclusions:The number of drug clinical trials for oral disease in China has generally shown an increasing trend, but there are still problems such as small number of clinical trials, low proportion of investment in new drug development and international multicenter trials, concentrated indications of clinical trials and insufficient clinical trial experience in specialized oral medical institutions. Enhancing the enthusiasm and innovation capabilities of domestic pharmaceutical enterprises in the research and development of oral diseases drugs, exploring the advantages of traditional Chinese medicine/natural medicine resources for oral diseases, and establishing a clinical research system in specialized oral medical institutions are of great significance for the development of oral drugs.

Objective:To evaluate the diagnostic efficacy of serum anti-deamidated gliadin peptide antibody immunoglobulin A (DGP-IgA) in adult celiac disease.Methods:A retrospective case-control study was conducted. Clinical data of 80 adult celiac disease patients (celiac disease group) treated in the Department of Gastroenterology of the People's Hospital of Xinjiang Uygur Autonomous Region from September 2020 to December 2023 were collected. Meanwhile, 40 healthy individuals who underwent physical examinations were selected as the healthy control group. According to the Oslo definition of celiac disease, 80 celiac disease patients were classified into classical type (52 patients), non-classical type (21 patients), and subclinical type (7 patients). Serum DGP-IgA and anti-tissue transglutaminase antibody immunoglobulin A (tTG-IgA) were measured in both celiac disease and healthy control groups by using the ELISA method. The degree of intestinal mucosal damage in celiac disease patients was assessed by the Marsh Oberhuber histopathological grading system (Marsh grading for short) using the small intestinal biopsy pathological results. Statistical analysis was performed to compare the differences in serum DGP-IgA and tTG-IgA between the two groups, as well as the differences in antibodies among different clinical phenotypes. Spearman's rank correlation analysis was used to evaluate the correlation between serum DGP-IgA level and Marsh grading. Receiver operating characteristic (ROC) curves were plotted to analyze the diagnostic efficacy of DGP-IgA, tTG-IgA, and the combination of DGP-IgA and tTG-IgA for celiac disease.Results:Among the 80 celiac disease patients, there were 19 males and 61 females, with a mean age of 45.31 ± 14.96 years. In the healthy control group, there were 15 males and 25 females, with a mean age of 47.03 ± 11.86 years. There were no statistically significant differences in age and gender between the two groups (both P > 0.05). The level of DGP-IgA and tTG-IgA in the celiac disease group were significantly higher than those in the healthy control group [DGP-IgA: 308.31 (279.86, 349.92) U/ml vs. 269.85 (251.42, 290.40) U/ml, P < 0.01; tTG-IgA: 261.05 (79.23, 2 542.30) U/ml vs. 1.90 (1.90, 2.40) U/ml, P < 0.01]. Further subtype analysis revealed that DGP-IgA level in classical celiac disease patients was higher than that in subclinical celiac disease patients [314.63 (289.35, 357.30) U/ml vs. 275.65 (260.90, 296.72) U/ml, P < 0.05], with statistically significant difference. Serum DGP-IgA level in celiac disease patients was positively correlated with Marsh grading ( r = 0.343, P < 0.01). The ROC curve results showed that the area under curve (AUC) for serum DGP-IgA in diagnosing celiac disease was 0.768, with an optimal cutoff value of 292.51 U/ml, sensitivity of 66.3%, and specificity of 77.5%; AUC for serum tTG-IgA was 0.974, with an optimal cutoff value of 20.1 U/ml, sensitivity of 92.5%, and specificity of 95.0%; AUC for the combination of DGP-IgA and tTG-IgA was 0.991, with a sensitivity of 98.8% and specificity of 97.5%. Conclusions:Serum DGP-IgA alone has limited clinical significance in diagnosing adult celiac disease. The diagnostic efficacy can be improved only when combined with tTG-IgA detection.

Objective:To analyze the current status of clinical trials of Chinese materia medica for the purpose of registration in China; To provide reference for the research and development of new TCM drugs.Methods:Clinical trials of Chinese materia medica/natural medicine registered in Drug Clinical Trial Registration and Information Disclosure Platform were retrieved from inception to December 31, 2024. Excel 2019 software was used to input and analyze the data such as the number of registered clinical trials, date of first publication, study status, field of indication, trial phases, sponsors, group leader, and design types.Results:A total of 1 137 Chinese materia medica clinical trials had been registered, accounting for 4.12% of the total number registered on the platform. Phase Ⅱ clinical trials accounted for the highest proportion (58.8%), and 99.7% of clinical trials conducted domestically. The sponsors were predominantly domestically pharmaceutical enterprises. These 1 137 clinical trials of Chinese materia medica clinical trials involved 752 drug categories, 28 dosage forms, and 796 varieties (the same class of drugs had different drug dosage forms), with capsules being the most common. The indications primarily focused on respiratory, digestive, cardio-cerebrovascular, neuropsychiatric, gynecological diseases. The group leader of clinical trials was distributed in 28 provinces, among which the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine as the group leader, undertook the most clinical trials of TCM. 89.9% of the clinical trials adopted the randomized controlled trial design, and only 31.9% of the clinical trials purchased insurance for the subjects.Conclusion:The research and development of new TCM drugs has entered a phase of vigorous development. Further efforts are still needed in establishing systematic guidelines for Chinese materia medica clinical trials, accelerating the internationalization of TCM, exploring innovative dosage forms and indications, and strengthening the protection of participants' rights.

Objective:To review drug clinical trial development in Shaanxi province and to understand the effectiveness of the implementation of a record system in promoting drug clinical trial development.Methods:Based on the data of drug clinical trials in Shaanxi province released on the official website of the National Medical Products Administration, this study made a statistical analysis of the number of drug clinical trial institutions, regional distribution, registered majors and principal investigators, and the development of drug clinical trial projects.Results:After implementing drug clinical trial institution registration, the drug clinical trial institutions in Shaanxi Province developed rapidly, increasing from 20 in the qualification period to 46, with a growth rate of 130%. A total of 113 specialties were recorded, of which the highest number of professional records were for endocrinology and oncology. 46 institutions recorded 1, 094 principal investigators and participated in 3803 drug clinical trial projects. However, only 8 institutions had undertaken drug clinical trial projects as group leaders.Conclusions:The number of drug clinical trial institutions in Shaanxi province increased significantly, reflecting a good overall development status. However, issues still exist, such as unbalanced development of clinical trial resources within the region, insufficient researchers with the ability to conduct clinical trials, relatively concentrated drug clinical trial projects, and lack of experience in undertaking clinical trials as a group leader.
