Bruton's Tyrosine Kinase Inhibitors in Refractory or Relapsing Primary Central Nervous System Lymphoma: A Meta-analysis and Systematic Review.

BACKGROUND: Primary central nervous system lymphoma (PCNSL) is an aggressive lymphoma that primarily affects the central nervous system. Current treatments, such as surgery, chemotherapy, and whole-brain radiotherapy, often fail to achieve satisfactory results. The prognosis for patients with refractory or relapsed (R/R) PCNSL is bleak. The optimal treatment for refractory or relapsed PCNSL is poorly defined due to a limited number of studies in this setting. Bruton's tyrosine kinase (BTK) inhibitors, as part of targeted therapy regimens, have undergone testing in several clinical trials against PCNSL and have shown promising results in the treatment of R/R PCNSL. In this meta-analysis, we aim to explore and critically appraise the evidence regarding the efficacy of BTK inhibitors in the treatment of refractory or relapsed PCNSL. METHODS: A systematic search was conducted on multiple databases including PubMed, Embase, Cochrane library, Wanfang Data Knowledge Service Platform, and CNKI, covering the period up to November 2023. The inclusion criteria for studies were patients with R/R PCNSL who received BTK inhibitors, and reported data on overall response rate (ORR) and complete remission (CR). The pooled rates were calculated using a random-effects or fixed-effects model with a double arcsine transformation, and 95% CIs were determined for all outcomes. RESULTS: In total, 1 studies involving 185 patients were identified and included in the meta-analysis. The pooled complete remission (CR) rate of BTK inhibitors-based treatment for R/R PCNSL was found to be 50%. Subgroup analysis revealed that the CR rates for BTK inhibitor monotherapy, BTK inhibitor combined with chemotherapy, and BTK inhibitor combined with radiotherapy for R/R PCNSL were 7%, 68%, and 80%, respectively. The ORR for BTK inhibitors-based treatment for R/R PCNSL was 70%. Subgroup analysis showed that the ORR rates for BTK inhibitor monotherapy and BTK inhibitor combined with chemotherapy for R/R PCNSL were 55% and 83%, respectively. The most common adverse events (AEs) reported were hematologic AEs, including neutropenia, anemia, and thrombocytopenia. Severe nonhematologic AEs included rash, febrile neutropenia, increased levels of aspartate aminotransferase, and increased blood bilirubin. CONCLUSIONS: BTK inhibitors can be regarded as a safe and effective treatment option for R/R PCNSL, thereby providing a potential new avenue for R/R PCNSL treatment. However, it is important to note that further large-sample prospective randomized controlled trials are needed to validate these findings and establish their wider applicability.

[Clinical observation of transurethral holmium laser enucleation of prostate by two-way rendezvous and trenching].

OBJECTIVE: Exploring the clinical efficacy, safety, and surgical techniques of two-way rendezvous and trenching method for transurethral holmium laser prostatectomy in the treatment of benign prostatic hyperplasia. METHODS: Retrospective analysis of clinical data on preoperative, intraoperative, and postoperative follow-up of 326 patients with benign prostatic hyperplasia who underwent two-way rendezvous and trenching method of transurethral holmium laser prostatectomy at the Urology Department of Wujin People's Hospital in Changzhou City from January 2020 to January 2023. RESULTS: Compared with preoperative measures, IPSS symptom score, quality of life (QoL) score, maximum urinary flow rate (Qmax), and residual urine volume (PVR) were significantly improved at 1, 6, and 12 months postoperatively (P<0.05). Thirty two patients with normal and regular sexual life pre-operation were observed. There were no significant changes in their IIEF-5 score and Erectile Hardness Scale (EHGS) score after surgery compared with pre-operation (P<0.05). There were 9 patients (28.12%) with retrograde ejaculation after surgery. CONCLUSION: The two-way rendezvous and trenching method of transurethral holmium laser prostatectomy is a safe and effective method for treating benign prostatic hyperplasia, with precise results, high safety, minimal trauma, and fast postoperative recovery.

[Comparison of therapeutic effects between holmium laser and plasma transurethral enucleation in the treatment of benign prostatic hyperplasia].

OBJECTIVE: Comparison of clinical efficacy between transurethral holmium laser prostate enucleation (two-way rendezvous and trenching method) and transurethral plasma enucleation. METHODS: A total of 483 patients with benign prostatic hyperplasia who were admitted to our hospital from December 2019 to December 2022 were randomly divided into an observation group (245 cases) and a control group (238 cases) using a random number table method. The observation group underwent transurethral holmium laser prostatectomy, while the control group underwent transurethral plasma prostatectomy,evaluate the efficacy of two surgical methods. RESULT: The IPSS symptom score, quality of life (QOL) score, maximum urinary flow rate (Qmax), residual urine volume (PVR) and other indicators were significantly improved in both groups after 6 months of surgery compared to before (P<0.05), and there was no statistically significant difference between the two groups (P>0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group (P<0.05). There was no statistically significant difference in sexual function and retrograde ejaculation between the two groups of patients(P>0.05). CONCLUSION: Both surgical methods have good surgical efficacy, but compared with prostate plasma resection, holmium laser prostatectomy can reduce intraoperative bleeding in patients with BPH, effectively shorten catheter retention time, patient hospitalization time, and postoperative bladder flushing time, resulting in higher quality of life and safety.

Electroacupuncture Stimulation of Language-Implicated Acupoint Tongli (HT 5) in Healthy Subjects: An fMRI Evaluation Study.

OBJECTIVE: To explore brain activations associated with electroacupuncture simulation at Tongli (HT 5) and its comparison with brain activations during picture-naming task. METHODS: Twenty healthy subjects were enrolled in this study. Half of them received electroacupuncture stimulation at HT 5 (ACUP group) and the other half of them received stimulation at a nonmeridian sham acupoint (SHAM group). All subjects performed picture-naming task. Each subject finished two runs of functional magnetic resonance imaging examinations in one session and picture-naming task was performed before electroacupuncture stimulation. Subjective brain activations were obtained using generalized linear model and inter-group analyses were performed after that. RESULTS: The electroacupuncture stimulation at HT 5 induced significant brain activations in both the anterior and posterior language regions, including the left inferior frontal gyrus, which was in consistent with activations induced during picture-naming task. Group analysis showed a tendency of increased activation of ACUP group in left inferior frontal gyrus compared with SHAM group (P<0.05 FDR corrected). CONCLUSIONS: Electroacupuncture treatment at the acupoint HT 5 has modulation effect on typical language-implicated brain regions in healthy subjects, which provides supporting evidence for beneficial effects of needling at HT 5 for recovery of language function in aphasia.

Anchoring Nitrogen-Doped TiO2 Nanocrystals on Nitrogen-Doped 3D Graphene Frameworks for Enhanced Lithium Storage.

An advanced architecture design of nitrogen-doped TiO2 anchored on nitrogen-doped 3D graphene framework composites (denoted as N-TiO2 /N-3D GFs) have been fabricated by a facile template process and further NH3 treatment. The 3D graphene framework allows the electrolyte to penetrate into the inverse opal structure, and possesses high electronic conductivity. The close contact between the N-TiO2 and the graphene suppresses the growth and aggregation of TiO2 nanoparticles during heating process, leading to decreased Li+ diffusion length. The N-doping in both TiO2 and the graphene matrix could improve the electronic conductivity on the TiO2 particle surface and between adjacent particles. As expected, when used as an anode for Li-ion batteries (LIBs), the N-TiO2 /N-3D GFs composite delivers an excellent reversible capacity of 165 mA h g-1 after 200 cycles at 100 mA g-1 and an outstanding rate capability of 114 mA h g-1 after 1000 cycles at 1 Ag-1 . With rational design, this strategy could be extended to other electrode materials that may hold great promise for the development of high energy storage systems.
