Gliomas are the most common primary neuroepithelial tumors of the central nervous system in adults, of which glioblastoma is the deadliest subtype. Apart from the intrinsically indestructible characteristics of glioma (stem) cells, accumulating evidence suggests that the tumor microenvironment also plays a vital role in the refractoriness of glioblastoma. The primary functions of platelets are to stop bleeding and regulate thrombosis under physiological conditions. Furthermore, platelets are also active elements that participate in a variety of processes of tumor development, including tumor growth, invasion, and chemoresistance. Glioma cells recruit and activate resting platelets to become tumor-educated platelets (TEPs), which in turn can promote the proliferation, invasion, stemness, and chemoresistance of glioma cells. TEPs can be used to obtain genetic information about gliomas, which is helpful for early diagnosis and monitoring of therapeutic effects. Platelet membranes are intriguing biomimetic materials for developing efficacious drug carriers to enhance antiglioma activity. Herein, we review the recent research referring to the contribution of platelets to the malignant characteristics of gliomas and focusing on the molecular mechanisms mediating the interaction between TEPs and glioma (stem) cells, as well as present the challenges and opportunities in targeting platelets for glioma therapy.

Objective:To analyze the reoperation rate and causes during the early adoption phase of unilateral biportal endoscopy (UBE).Methods:The clinical data of 180 patients who underwent UBE performed by a single surgeon at Beijing Friendship Hospital, Capital Medical University from October 2021 to June 2023 were retrospectively analyzed. Clinical and imaging data of patients who underwent reoperation were collected to analyze the causes of reoperation, and the clinical efficacy of the reoperations was also followed up. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used before and after treatment. Results:A total of 180 patients who underwent UBE were included in this study, of which 6 patients underwent reoperation, and the reoperation rate was 3.33%. Among them, 3 cases occurred in the first 90 surgeries and the other 3 occurred in the subsequent 90 surgeries. The causes of reoperation were as follows: recurrent lumbar disc herniation at the same segment postoperatively in 2 cases, insufficient decompression in 2 cases, disc herniation following isolated decompression in 1 case, and immediate postoperative perianal numbness in 1 case. The time between the initial surgery and reoperation ranged from 0 to 187 days, with an average of 63.3 days. The average follow-up time after reoperation was 18.3 months. The visual analogue scale (VAS) and Oswestry disability index (ODI) scores of the patients at the last follow-up were significantly improved compared with those before operation (VAS score of low back pain: 5.2 ± 1.7 before operation, 1.2 ± 0.8 at the last follow-up, P<0.001; VAS score of leg pain: 7.2 ± 1.5 before operation, 1.2 ± 1.2 at the last follow-up, P<0.001; ODI score: 67.3 ± 5.7 before operation, 20.2 ± 8.2 at the last follow-up, P<0.001). The postoperative modified MacNab scores were generally satisfactory (4 cases were rated as excellent, accounting for 66.7%; 2 cases were rated as good, accounting for 33.3%). Except for one patient who experienced dural injury during open revision surgery, there were no serious complications such as nerve damage. Conclusions:In the early stages of UBE surgery, recurrent lumbar disc herniation and inadequate decompression are the primary reasons for reoperation, typically occurring within the first three months postoperatively. Reoperation does not significantly increase the risk of nerve injury. Enhanced early postoperative follow-up is recommended. For symptomatic patients, a second surgery with thorough decompression can yield satisfactory treatment outcomes.

Programmed cell death 1 ligand 1 (PD-L1) is an important immunosuppressive molecule, which inhibits the function of T cells and other immune cells by binding to the receptor programmed cell death-1. The PD-L1 expression disorder plays an important role in the occurrence, development, and treatment of sepsis or other inflammatory diseases, and has become an important target for the treatment of these diseases. Mesenchymal stem cells (MSCs) are a kind of pluripotent stem cells with multiple differentiation potential. In recent years, MSCs have been found to have a strong immunosuppressive ability and are used to treat various inflammatory insults caused by hyperimmune diseases. Moreover, PD-L1 is deeply involved in the immunosuppressive events of MSCs and plays an important role in the treatment of various diseases. In this review, we will summarize the main regulatory mechanism of PD-L1 expression, and discuss various biological functions of PD-L1 in the immune regulation of MSCs.

Objective It compared the power consumption and electrical parameters between Thulium fiber laser devices(TFL)and Holmium laser devices(HoL)in transurethral enucleation of prostate(TUEP).Methods A sin-gle surgeon conducted TUEP by THL or HoL in 10 patients respectively.The enucleation efficiency,the laser energy output and the electric parameters were recorded and analyzed.Results The data from both groups of surgeries were tested for normal distribution,and the t-test found that the difference in the enucleation efficiency between the two surgeries was not statistically significant(P=0.818),and the energy consumption indexes of the two devices were comparable.The difference in the total kilojoules of laser emission between the two lasers during surgery was not statistically significant(P=0.148),but the power consumption of the thulium laser was about one-tenth of that of the holmium laser(P＜0.001),suggesting that the former utilised electrical energy significantly more efficiently than the latter.The maximum current of the HoL was significantly higher than that of the TFL(P＜0.001),requiring a spe-cial high-power power outlet.Conclusion TFL was superior to HoL in terms of lower power consumption,higher en-ergy-efficient and electrical convenient in transurethral enucleation of the prostate.

ObjectiveTo explore the role of saikosaponin D （SSD） targeting signal transducer and activator of transcription 3 （STAT3） in inducing apoptosis of bladder cancer cells by computer-aided drug design and experimental verification. MethodThe druggability and biotoxicity of SSD were explored by Bayesian classifier modeling. The information about SSD， the active ingredient of Bupleuri Radix， was searched against the Traditional Chinese Medicine Systematic Pharmacology Database and Analysis Platform （TCMSP）. The targets of SSD were predicted by PubChem， TCMSP， a Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine （BATMAN-TCM）， Coremine， an Encyclopedia of Traditional Chinese Medicine （ETCM）， and SwissTargetPrediction. GeneCards， Therapeutic Target Database （TTD）， and Online Mendelian Inheritance in Man （OMIM） were employed to predict the potential therapeutic targets of bladder cancer. Then， the common targets shared by SSD and bladder cancer were selected for Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses. Molecular docking was adopted to explore the binding affinity and structural stability of SSD with target proteins. Cytoscape 3.9.1 was used to construct the STAT3-drug regulatory network and STAT3-apoptosis regulatory network. UM-UC-3 cells were treated with 0， 5， 10， 15 μmol·L^-1 SSD for 24 h. Then， flow cytometry was used to detect the apoptosis of bladder cancer cells， and Western blot was employed to determine the protein levels of B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， Bcl-2-associated death promoter （Bad）， STAT3， and phosphorylation （p）-STAT3. ResultBayesian classifier modeling and molecular docking showed that SSD had low biotoxicity and bound well to the target protein STAT3 to form a stable protein-ligand complex. There were 282 common targets between bladder cancer and SSD， among which STAT3 was the most central target. The GO enrichment analysis showed that the potential core therapeutic targets involved 3 036 biological processes， 82 cellular components， and 171 molecular functions. The KEGG enrichment analysis showed that the potential core targets were mainly related to the C-type lectin receptor signaling pathway， Toll-like receptor signaling pathway， and cell apoptosis pathway. The STAT3-drug regulatory network and STAT3-apoptosis regulatory network showed that 29 drugs interacted with STAT3， and 27 apoptosis-related genes had a strong correlation with STAT3. Flow cytometry showed that the apoptosis rate increased with the increase in SSD concentration （P<0.05）. Western blotting results showed that SSD down-regulated the protein levels of p-STAT3 and Bcl-2 and up-regulated the protein levels of Bax and Bad in a concentration-dependent manner （P<0.05）. ConclusionSSD has good druggability and low biotoxicity. It may promote the apoptosis of bladder cancer cells by targeting STAT3.
