BACKGROUND:
Several studies have demonstrated the occurrence of secondary tumors as a rare but significant complication of chimeric antigen receptor T (CAR-T) cell therapy, underscoring the need for a detailed investigation. Given the limited variety of secondary tumor types reported to date, a comprehensive characterization of the various secondary tumors arising after CAR-T therapy is essential to understand the associated risks and to define the role of the immune microenvironment in malignant transformation. This study aims to characterize the immune microenvironment of a newly identified secondary tumor post-CAR-T therapy, to clarify its pathogenesis and potential therapeutic targets.
METHODS:
In this study, the bone marrow (BM) samples were collected by aspiration from the primary and secondary tumors before and after CD19 CAR-T treatment. The CD45 + BM cells were enriched with human CD45 microbeads. The CD45 + cells were then sent for 10× genomics single-cell RNA sequencing (scRNA-seq) to identify cell populations. The Cell Ranger pipeline and CellChat were used for detailed analysis.
RESULTS:
In this study, a rare type of secondary chronic myelomonocytic leukemia (CMML) were reported in a patient with diffuse large B-cell lymphoma (DLBCL) who had previously received CD19 CAR-T therapy. The scRNA-seq analysis revealed increased inflammatory cytokines, chemokines, and an immunosuppressive state of monocytes/macrophages, which may impair cytotoxic activity in both T and natural killer (NK) cells in secondary CMML before treatment. In contrast, their cytotoxicity was restored in secondary CMML after treatment.
CONCLUSIONS
This finding delineates a previously unrecognized type of secondary tumor, CMML, after CAR-T therapy and provide a framework for defining the immune microenvironment of secondary tumor occurrence after CAR-T therapy. In addition, the results provide a rationale for targeting macrophages to improve treatment strategies for CMML treatment.

Allergic rhinitis (AR), a globally prevalent immune-mediated inflammatory condition, is still an incurable disease. In the present study, we have validated the impact of the Kelch-like ECH associated protein 1 (Keap1)-related oxidative stress and inflammatory response in clinical AR patient peripheral blood and nasal swab samples, emphasizing the biological relevance of Keap1 and AR. Targeting Keap1 -nuclear factor erythroid 2-related factor 2 (Nrf2) related anti-oxidative stress may be effective for AR intervention. Drawing inspiration from the Keap1 homodimerization and the E3 ligase characteristics, we herein present a design of novel bivalent molecules for chemical knockdown of Keap1. For the first time, we characterized ternary complexes of Keap1 dimer and one molecule of bivalent compounds. The best bivalent molecule 8 encompasses robust capacity to degrade Keap1 as a homoPROTACKEAP1. It efficaciously suppresses inflammatory cytokines in extensively different cells, including human nasal epithelial cells. Moreover, in an AR mouse model, we confirmed that the chemical degradation induced by homoPROTACKEAP1 led to therapeutic benefits in managing AR symptoms, oxidative stress and inflammation. In summary, our findings underscore the efficacy of targeting the Keap1 system through the homoPROTAC-ing technology as an innovative and promising treatment strategy for the incurable allergic disorders.

The chemical complexity of traditional Chinese medicines (TCMs) makes the active and functional annotation of natural compounds challenging. Herein, we developed the TCMs-Compounds Functional Annotation platform (TCMs-CFA) for large-scale predicting active compounds with potential mechanisms from TCM complex system, without isolating and activity testing every single compound one by one. The platform was established based on the integration of TCMs knowledge base, chemome profiling, and high-content imaging. It mainly included: (1) selection of herbal drugs of target based on TCMs knowledge base; (2) chemome profiling of TCMs extract library by LC‒MS; (3) cytological profiling of TCMs extract library by high-content cell-based imaging; (4) active compounds discovery by combining each mass signal and multi-parametric cell phenotypes; (5) construction of functional annotation map for predicting the potential mechanisms of lead compounds. In this stud TCMs with myocardial protection were applied as a case study, and validated for the feasibility and utility of the platform. Seven frequently used herbal drugs (Ginseng, etc.) were screened from 100,000 TCMs formulas for myocardial protection and subsequently prepared as a library of 700 extracts. By using TCMs-CFA platform, 81 lead compounds, including 10 novel bioactive ones, were quickly identified by correlating 8089 mass signals with 170,100 cytological parameters from an extract library. The TCMs-CFA platform described a new evidence-led tool for the rapid discovery process by data mining strategies, which is valuable for novel lead compounds from TCMs. All computations are done through Python and are publicly available on GitHub.

BACKGROUND:
LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.
METHODS:
We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.
RESULTS:
On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).
CONCLUSION:
LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.

Objective:To investigate the effect of different timing of urinary catheter removal on postoperative recovery of elderly patients undergoing transurethral resection of prostate (TURP) .Methods:A total of 159 elderly patients undergoing TURP from Beijing Friendship Hospital Affiliated to Capital Medical University from March 2021 to June 2022 were selected as research objects by convenience sampling method, and were divided into the urinary catheter removal within 48 h after surgery group ( n=47), urinary catheter removal within 48 to 72 h after surgery group, urinary catheter removal>72 h after surgery group. The degree of dysuria after catheter removal, incidence of urinary tract infection, secondary catheter insertion rate and postoperative hospital stay were compared among the three groups. Results:The proportion of patients with moderate or above dysuria of the urinary catheter removal within 48 to 72 h after surgery group was lower than those of the urinary catheter removal within 48 h after surgery group and the urinary catheter removal>72 h after surgery group, and the differences were statistically significant ( P<0.05). The incidence of urinary tract infection of the urinary catheter removal within 48 h after surgery group and the urinary catheter removal within 48 to 72 h after surgery group were lower than that of the urinary catheter removal>72 h after surgery group, and the differences were statistically significant ( P<0.05). The rate of secondary catheterization of the urinary catheter removal within 48 to 72 h after surgery group and the urinary catheter removal>72 h after surgery group were lower than that of the urinary catheter removal within 48 h after surgery group, and the differences were statistically significant ( P<0.05). The postoperative hospital stay of the curinary catheter removal within 48 to 72 h after surgery group was shorter than those of the urinary catheter removal within 48 h after surgery group and the urinary catheter removal>72 h after surgery group, and the differences were statistically significant ( P<0.05) . Conclusions:Removing urinary catheter within 48 to 72 h after surgery can effectively reduce the degree of urination difficulty in elderly patients undergoing TURP, the incidence of urinary tract infection and the rate of secondary catheterization, and shorten the postoperative hospital stay.

This study systematically and comprehensively sorted out the application status of Chinese patent medicines for the treatment of constipation in the clinic, to provide scientific evidence for future research directions and clinical drug use in this field. Based on the method of scoping review, the Chinese patent medicines for the treatment of constipation were retrieved from three drug lists to obtain the medicines that needed to be evaluated. A comprehensive and systematic search was carried out on the included studies on the treatment of constipation by Chinese patent medicines through eight Chinese and English databases, and the included studies were integrated and analyzed. The results were displayed in combination with charts. Thirty-four Chinese patent medicines and 118 studies were included in this study. According to the efficacies, Chinese patent medicines were divided into 4 categories, namely eliminating accumulation, purging fire, promoting Qi, and moistening bowels, involving 125 Chinese medicines. The overall attention of constipation research is on the rise. Marenwan (granules or soft capsules) gained the highest attention, with 42 studies, followed by Qirong Runchang oral liquid, with 21 studies, and Biantong tablets (capsules), with 19 studies. There are 10 studies on Congrong Tongbian oral liquid. Seventeen Chinese patent medicines had no corresponding clinical research. There were 8 study design types, and all drugs were mainly randomized controlled trials except Danggui Longhui pill. Among the intervention types, the comparison between Chinese patent medicines and western medicines was the most. The highest outcome indicators were efficacy, safety evaluation, and main symptoms or scores, and there was a lack of a unified core outcome indicator set. There were few studies on adverse reactions and the economy. Only 11.86% of the studies were funded. Clinically, Chinese patent medicines are widely used in the treatment of constipation, and the amount of related research shows an increasing trend. However, some Chinese patent medicines lack corresponding clinical evidence, and the published research has problems such as unrigorous design, ununified criteria for efficacy evaluation, lack of comprehensive evidence studies, and insufficient funds. It is hoped that more investment will be made in this field in the future, and more attention will be paid to drugs with relatively blank research and constipation syndromes with few treatments. Comprehensive evidence studies such as systematic reviews should be carried out actively. And the study design should be standardized to provide reliable evidence for the treatment of constipation with Chinese patent medicines.
