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 identify the potential long non-coding RNA (lncRNA) expressed in rheumatoid arthritis (RA) synovium key to RA onset and investigate its association with immune cell infiltration. Methods RA synovium data were downloaded from the GEO database and normalized. The lncRNAs key to RA onset were identified using multiple machine learning methods. Infiltration of 22 immune cell populations in RA synovium was measured by cell-type identification by estimating relative subsets of RNA transcripts (CIBER-SORT). The relationship between the key lncRNA and infiltrating immune cells was analyzed. Finally, real-time quantitative PCR was applied to validate the expression of the key lncRNA in RA synovial cells. Results lncRNA human leukocyte antigen complex P5(HCP5) was identified as the key lncRNA associated with RA onset. Infiltration analysis revealed increased abundance of CD8+ T cells, γδ T cells, and M1 macrophages while decreased abundance of M2 macrophages in RA synovial tissue. Correlation analysis demonstrated that the lncRNA HCP5 expression was positively associated with the infiltration abundance of CD8+ T cells, γδ T cells, and M1 macrophages in RA synovial tissue. Furthermore,the expression of lncRNA HCP5 in RA synovial cells was up-regulated. Conclusion lncRNA HCP5 expression is up-regulated in RA synovial tissue and potentially associated with immune cells infiltration.

Objective:To explore the differences of regulator of G protein signaling 4 (RGS4) gene polymorphisms and methylation between schizophrenia and healthy controls, as well as the association between gene polymorphisms and methylation.Methods:A total of 129 schizophrenia patients and 131 healthy controls from Southen Fujian were enrolled in this study. The peripheral blood DNA of all the subjects was extracted.The three polymorphic loci of RGS4 (rs10759, rs12753561 and rs951436) were amplified, sequenced, and then genotyped. In addition, 32 subjects were randomly selected from the two groups respectively and the gene methylation level of RGS4 was detected by sequencing after bisulfite treatment. SPSS 20.0 software was used for data analysis. The χ2 test and independent sample t-test were used to analyze the difference of gene methylation of RGS4.Two-way ANOVA was used to analyze the association between RGS4 gene polymorphism and methylation. Results:There were three genotypes of AA, AC and CC for rs10759 locus in the subjects of patient group and control group. And the distribution difference of genotypes between the two groups was statistically significant ( χ2=6.431, P=0.040), but there was no significant difference in allele frequency( χ2=1.270, P=0.260). For rs12753561, there were three genotypes of GG, GT and TT, and their distribution of genotypes was significantly different ( χ2=6.217, P=0.045). There was no significant difference for the allele frequency for rs12753561( χ2=0.021, P=0.885). For rs951436, there were three genotypes of AA, AC and CC, and there were no significant difference in genotype distribution and allele frequency distribution between the two groups( χ2=0.008, 0.007, both P>0.05). Methylated CpG sites were found in 26 patients and 27 healthy controls, and these were no significant difference between the two groups( χ2=0.110, P=0.740). There was no significant difference ( t=-0.318, P=0.752) of individual methylation rate (number of methylation sites/10) between schizophrenia patient group (0.24±0.11) and healthy control group (0.26±0.18). There was also no significant difference of methylation rate between male and female in both groups(both P>0.05). Finally, there was no significant difference of individual methylation rate among rs10759, rs12753561 and rs951436 genotypes (all P>0.05). Conclusion:RGS4 rs10759 and rs12753561 genotypes may be involved in schizophrenia, while RGS4 gene methylation has no association with schizophrenia. In addition, RGS4 gene polymorphism has no association with the methylation in the current experimental setting.

Organoid models are used to study kidney physiology, such as the assessment of nephrotoxicity and underlying disease processes. Personalized human pluripotent stem cell-derived kidney organoids are ideal models for compound toxicity studies, but there is a need to accelerate basic and translational research in the field. Here, we developed an automated continuous imaging setup with the "read-on-ski" law of control to maximize temporal resolution with minimum culture plate vibration. High-accuracy performance was achieved: organoid screening and imaging were performed at a spatial resolution of 1.1 μm for the entire multi-well plate under 3 min. We used the in-house developed multi-well spinning device and cisplatin-induced nephrotoxicity model to evaluate the toxicity in kidney organoids using this system. The acquired images were processed via machine learning-based classification and segmentation algorithms, and the toxicity in kidney organoids was determined with 95% accuracy. The results obtained by the automated "read-on-ski" imaging device, combined with label-free and non-invasive algorithms for detection, were verified using conventional biological procedures. Taking advantage of the close-to-in vivo-kidney organoid model, this new development opens the door for further application of scaled-up screening using organoids in basic research and drug discovery.

Aberrant activation of oncogenic signaling pathways in tumors can promote resistance to the antitumor immune response. However, single blockade of these pathways is usually ineffective because of the complex crosstalk and feedback among oncogenic signaling pathways. The enhanced toxicity of free small molecule inhibitor combinations is considered an insurmountable barrier to their clinical applications. To circumvent this issue, we rationally designed an effective tumor microenvironment-activatable prodrug nanomicelle (PNM) for cancer therapy. PNM was engineered by integrating the PI3K/mTOR inhibitor PF-04691502 (PF) and the broad spectrum CDK inhibitor flavopiridol (Flav) into a single nanoplatform, which showed tumor-specific accumulation, activation and deep penetration in response to the high glutathione (GSH) tumoral microenvironment. The codelivery of PF and Flav could trigger gasdermin E (GSDME)-based immunogenic pyroptosis of tumor cells to elicit a robust antitumor immune response. Furthermore, the combination of PNM-induced immunogenic pyroptosis with anti-programmed cell death-1 (αPD-1) immunotherapy further boosted the antitumor effect and prolonged the survival time of mice. Collectively, these results indicated that the pyroptosis-induced nanoplatform codelivery of PI3K/mTOR and CDK inhibitors can reprogram the immunosuppressive tumor microenvironment and efficiently improve checkpoint blockade cancer immunotherapy.

Borderline personality disorder (BPD) is characterized by emotional regulation, interpersonal relationship, self-image and impulse control instability. It is a mental disorder with high morbidity, high mortality and difficult treatment. Psychotherapy is the main treatment for this disease. However, current mainstream psychotherapy, such as dialectical behavior therapy (DBT), has certain limitations, so it is necessary to find a more convenient and effective treatment method. Acceptance and commitment therapy (ACT), as the representative therapy of the third generation of cognitive therapy, aims to make individuals accept inevitable pain, find their own value and commit to action, and finally improve their psychological flexibility to live a meaningful life. ACT has been used in the treatment of a variety of mental disorders, and the effect is significant. By expounding the pathogenesis of BPD and the theoretical model of ACT, this paper analyzed the rationality and feasibility of ACT intervention in BPD from the pathological model and treatment model of ACT. Finally, the research results of ACT treating BPD in recent years were summarized. The results show that ACT provides a promising method for the treatment of BPD patients, however, more studies are needed to prove its use in this group and its specific mechanism.
