Objective To explore the expression and significance of miR-21 in patients with primary gout. Methods The patients were divided into 4 groups: 35 acute gout patients (AG), 50 intermittent gout patients (IG), 25 chronic gout patients (CG) and 39 healthy patients. Their peripheral blood were collected and laboratory indexes were recorded. The expression of miR-21 and Nod-like receptor pyrin domain-containing protein 3 (NLRP3) mRNA in the peripheral blood mononuclear cells (PBMCs) was detected by real-time quantitative polymerase chain reaction (RT-qPCR). The blood and clinical data of another 5 healthy volunteers were collected, their peripheral blood was stimulated with 100 μg/ml monosodium urate (MSU) for 1 hour, pho-sphate buffer (PBS) was used as controls, then the expression of microRNA (miR)-21, NLRP3, interleukin (IL)-1β mRNA was detected by RT-qPCR. Rank sum test and spearman correlation analysis were used for data analysis. Results In primary gout patients, the expression of miR-21 in AG [12 ×10-4 (8.0 ×10-4)], IG [9.4 ×10-4 (6.9 ×10-4)], CG [7.3 ×10-4 (5.6 ×10-4)] was significantly higher than that in healthy control group [1.0×10-4(2.0×10-4)] (Z=9.83, P=0.02], while the expression of NLRP3 in AG[0.0444(0.0233)], IG[0.0581(0.0326)], CG[0.0314(0.0198)] was significantly lower than that in healthy control group [0.0886(0.0359)] (Z=13.82, P<0.01). In the primary gout of IG group, the expression of miR-21 was positively correlated with NLRP3 mRNA (r=0.449, P=0.016). After stimulated by 100 μg/ml MSU, the expression of miR-21 of the stimulated group [8.78×10-4(14×10-4)] was higher than that in the control group [6.25×10-4(6×10-4)](Z=-2.203, P<0.05), and the expression of IL-1βin stimulated group [3.06(2.00)] was higher than that in the control group [2.64 (1.22] (Z=-2.203, P<0.05). The level of miR-21 in patients with primary gout was positively correlated with the level of uric acid (UA), glutamic oxaloacetic transaminase (AST) and glutamic pyruvic transaminase (ALT) (r=0.473, 0.639, 0.487, P<0.05). Conclusion The increase of miR-21 in patients with primary gout may be involved in the inflammatory reaction of gout.

Objective:To investigate the safety and efficacy of Belintoumab on the treatment of children with acute B-lymphoblastic leukemia (B-ALL).Methods:The clinical data of 10 children with CD 19+ B-ALL who were admitted to the Department of Pediatrics, the First Affiliated Hospital of Zhengzhou University from September 2021 to May 2022 and treated with Belintoumab were analyzed retrospectively. Results:Among the 10 cases, there were 6 recurrent cases, 3 cases with persistent minimal residual disease (MRD) positive after an initial treatment, and 1 case complicated with invasive candidiasis.Before treatment, bone marrow blasts ≥0.25, and that ranged 0.05-<0.25 were detected in 2 cases and 1 case, respectively.Seven cases had a complete remission (CR) of bone marrow, 6 of which were MRD positive and 1 case was MRD negative.After treatment with Belintoumab, the CR rate was 66.7% (2/3). The overall MRD negative rate was 88.9% (8/9), and the negative rate in previously MRD positive children was 100% (6/6). The median follow-up time was 4.1 (1.6-10.0) months after the application of Belintoumab.The overall survival (OS) rate was 70.0% (7/10). Eight MRD negative children received hematopoietic stem cell transplantation, and the OS rate was 75% (6/8). Survived children did not relapse until the last follow-up visit.Fever (90%, 9/10) was the most common adverse events, followed by neutropenia (90%, 9/10). One case (10%, 1/10) of neurotoxicity was seizures (grade 2) and one case (10%, 1/10) suffered cytokine release syndrome (grade 2), which did not influence the therapeutic efficacy of Belintoumab after symptomatic treatment.Conclusions:Belintoumab is safe and effective on the treatment of children with recurrent/refractory CD 19+ B-ALL, and those with MRD positive who have achieved CR in bone marrow have a higher rate of turning negative.Belintoumab can also be used as a bridge scheme for CD 19+ B-ALL children who cannot tolerate chemotherapy.

Objective This study reconstructed 4D-CBCT for fully automatic compensated sliding motion by incorporating the bilateral filtering into the Deformable Vector Field (DVF). Methods First, a motion compensated simultaneous algebraic reconstruction technique (Modified Simultaneous Algebra Reconstruction Technique, mSART) was used to generate a high quality reference phase by using all phase projection stogether with the initial 4D-DVFs, which were generated via Demons registration between 0% phase and each other phaseimage. The 4D-DVF was optimized by matching the forward projection of the deformed 0% phase with the measured projection of the target phase. The loss function’s DVF smoothing constrain term contained bilateral filtering kernel that contained: 1) an spatial domain Guassian kernel; 2) animage intensity domain Guassian kernel; and 3) a DVF domain Guassian kernel. By choosing suitable kernel variances, the sliding motion can be extracted. A non-linear conjugate gradient optimizer wasused. We validated the algorithm on a Non-Uniform Rotational B- spline based Cardiac-Torso (NCAT) phantom. Quantification was evaluated by: 1) the Root-Mean-Square-Error (RMSE) together with the Maximum-Error (MaxE); 2) the Dice coefficient of the extracted lung contour from the final reconstructed images and 3) the relative reconstruction error (RE) to evaluate the algorithm's performance. Results The motion trajectory's RMSE/MaxEare 0.796/1.02 mm for bilateral filtering reconstruction; and 2.704/4.08 mm for original reconstruction. Image content such a stherib position, the hearted gedefinition, the fibrous structures all had been better corrected with bilateral filtering. Conclusion We developed a bilateral filtering based fully automatic sliding motion compensated 4D-CBCT scheme. Digital phantom study confirmed the improved motion estimation and image reconstruction ability. It can be used as a 4D-CBCT image guidance tool for lung SBRTtreatment.
