Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

OBJECTIVE To establish the project approval evaluation system for traditional Chinese medicine （TCM） preparations in medical institutions guided by new drug conversion， to improve the success rate of approval for TCM preparations in medical institutions and lay the foundation for the later drug conversion. METHODS Research and development team used the literature research method and brainstorming method to list and organize relevant elements of project evaluation and determine the initial indicator system. Experts were consulted using the Delphi method to confirm the evaluation index. The weights were calculated based on the proportion of importance scores for each indicator and assigned specific scores to each item. The indicator system was used to evaluate 31 TCM preparations applied for filing by various departments of our hospital from April to July 2023. RESULTS After two rounds of 17 experts’ consultation， the final TCM preparation system included five primary indicators， i.e. theoretical basis， clinical research foundation， pharmaceutical foundation， prescription， and clinical value， as well as 17 secondary indicators including prescription source， traditional Chinese medicine theory， clinical positioning and so on. Human experience was considered as the item which would be rejected as one vote. Based on the above indicator system， our hospital further improved the filing and project approval process for TCM preparations in medical institutions. Among the 31 TCM preparations applied for filing by various departments from April to July 2023， 8 TCM preparations with a score ≥65 were selected for development. CONCLUSIONS The evaluation system is objective， comprehensive， and highly operable. It is suitable for the selection of TCM preparations in medical institutions before research and development.

Five new racemic N-acetyldopamine (NADA) trimers, asponchimides A-E (1-5), were isolated from Aspongopus chinensis, a prominent traditional Chinese medicinal insect employed for alleviating pain, treating indigestion, and addressing kidney ailments. Compounds 1-5 were successfully resolved by chiral high-performance liquid chromatography (HPLC), yielding five pairs of enantiomers: (+)- and (-)-asponchimides A-E (1a/1b-5a/5b). Their structural identities were discerned by extensive spectroscopic analyses, including high-resolution mass spectrometry (HRMS), ultraviolet-visible (UV-Vis) spectroscopy, infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR), and their absolute configurations were determined by electronic circular dichroism (ECD) calculations. Compounds 1-5 are pioneering instances of NADA trimers featuring a Δ⁷ double bond. When subjected to a series of bioassays, a majority of the compounds exhibited weak inhibitory activity against nitric oxide (NO) production in LPS-induced RAW 264.7 cells.

In the emergency of the outbreak of COVID-19 in December 2019, Shaanxi Provincial Health Committee mobilized several medical teams from major hospitals in the province, and, by relying on Xi’an Chest Hospital, jointly established an anti COVID-19 consortium to control and eradicate the epidemic in a short time. Information support is an important guarantee for winning this battle. In order to realize the efficient cooperation among multiple medical teams, we have carried out some exploratory and innovative information support services on the basis of the original information system of the chest hospital. In this process, we have gone through some detours. Some compromises were made on some problems that could not be solved in the short term. Finally, in an environment full of uncertainty, a set of information support management system with basically smooth operation was built through rapid trial and error adjustment. The system mainly includes the following aspects: support of the organizational structure and operation process of the anti-epidemic consortium, support for medical collaboration related businesses of multiple medical teams, and support for statistical reports and online meetings. Information support has played a very important role in this action, and this practice has also accumulated experience for us to deal with similar situations in the future.

Objective: To study the manifestations of digestive system of hospitalized patients with novel coronavirus pneumonia (NCP) in Wuhan, China, and to provide reference for disease control and treatment. Methods: The data of hospitalized patients with NCP in the Sino-French Branch of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology was retrospectively analyzed, which included general information, nucleic acid test, severity degree of disease, incubation period, initial symptoms and manifestations of digestive system. The general information, positive rate of nucleic acid detection, and manifestations of digestive system were compared between critical patients who required non-invasive or invasive assisted ventilation (critical group) and non-critical patients without assisted ventilation (non-critical group). Continuous corrected chi-square test and independent sample median test were performed for statistical analysis. Results: Among the 305 patients there were 146 males (47.9%) and 159 females (52.1%), median age 57 years old. Nucleic acid assay of nasopharynx swab or pharynx swab of 84.1% (228/271) patients were positive. Forty-six patients (15.1%) were in critical group and 259 patients (84.9%) were in non-critical group. The incubation period was one to fifteen days, and the median period was six days. The initial symptoms mainly were fever (81.1%, 163/201), cough (39.3%, 79/201), fatigue (54.7%, 110/201), and loss of appetite (50.2%, 101/201). In one to ten days after the disease onset, 79.1% (159/201) of patients developed gastrointestinal symptoms including nausea (29.4%, 59/201), vomiting (15.9%, 32/201), or abdominal pain (6.0%, 12/201). 49.5% (146/295) of patients had diarrhea, median time was 3.3 days, (3.3±1.6) times per day, and a duration of (4.1±2.5) days. Excluding possible drug-related diarrhea, the incidence of diarrhea still was 22.2%. Only 6.9% (4/58) of patients were found leukocytes or fecal occult blood positive in regular stool test. ALT, AST, or bilirubin increased in 39.1% (119/304) of patients at admission. Patients with ALT or AST ≥ 80 U/L only accounted for 7.9% (24/304) and 6.3% (19/304), respectively. About 2.0% (6/304) of patients also had increased bilirubin level, average level was (37.4 ± 21.1) μmol/L. The median age of critical group was older than that of non-critical group (65.5 years vs. 56 years), at admission the rates of abnormal liver function test abnormal and slightly increased AST (40~80 U/L) of critical group were both higher than those of non-critical group (67.4% (31/46) vs. 34.1% (88/258) and 47.8% (22/46) vs. 21.7% (56/228)), and the differences were statistically significant (x²=5.885, 18.154 and 15.723;all P <0.05). There were no statistically significant differences in the proportion of male (58.7% (27/46) vs. 45.9% (119/259)), the positive rate of nucleic acid detection (94.6% (35/37) vs. 82.5% (193/234)), the percentage of patients with gastrointestinal symptoms (85.0% (17/20) vs. 78.5% (142/181)), the rate of diarrhea (44.7% (17/38)vs. 50.2% (129/257)) and ratio of patients with abnormal bilirubin level (6.5% (3/46) vs. 1.2% (3/258)) (all P>0.05). Conclusions The manifestation of digestive system of hospitalized NCP patients in Wuhan is significant, the ratio of patients with diarrhea and abnormal aminotransferase level is high. And at admission the rate of patients with abnormal liver function rate of critical group is higher than that of non-critical group, which will provide reference for the prevention and treatment of NCP.
