目的:基于灰狼优化算法(GWO)优化传统BP神经网络的舌诊图像颜色校正算法,解决移动舌诊APP存在的拍摄环境具有局限性、手机设备的依赖性及基于手机平台的颜色校正方法所使用的传统算法效果不佳等问题。方法:以24色标准色卡为标准,分别采集室内白炽灯不同光照强度场景与室外不同时刻阴天、晴天场景下的舌诊图像;同时选择灰度世界算法以及传统BP神经网络算法与本文算法进行对比,分别用上述三种算法对采集图像进行颜色校正,并对校正结果进行主观与客观颜色评价进行对比分析。结果:相比于灰度世界算法及BP神经网络算法,GWO-BP神经网络算法的颜色校正效果明显提高。结论:GWO-BP算法可有效地对手机拍摄的舌诊图像进行颜色校正,从而提高色值精确度。

Atomically precise metal nanoclusters(MNCs),as a potential type of photoacoustic(PA)contrast agent,are limited in application due to their low PA conversion efficiency(PACE).Here,with hydrophilic Au25SR18(SR=thiolate)as model NCs,we present a result that weakly polar solvent induces aggregation,which effectively enhances PA intensity and *** PA intensity and PACE are highly dependent on the degree of aggregation,while the aggregation-enhanced PA intensity(AEPA)positively correlates to the protected *** an AEPA phenomenon indicates that aggregation actually accelerates the intramolecular motion of Au NCs,and enlarges the proportion of excited state energy dissipated through vibrational *** result conflicts with the restriction of intramolecular motion mechanism of aggregation-induced *** experiments show that the increased energy of AEPA originates from the aggregation inhibiting the intermolecular energy transfer from excited Au NCs to their surrounding medium molecules,including solvent molecule and dissolved oxygen,rather than restricting radiative *** study develops a new strategy for enhancing the PA intensity of Au NCs,and contributes to a deeper understanding of the origin of the PA signal and the excited state energy dissipation processes for MNCs.

目的探讨急性白血病合并髓外浸润患者的临床特点、治疗方法和预后。方法回顾性分析贵州医科大学附属医院2014年4月至2023年4月收治的47例急性白血病合并髓外浸润患者的临床特点、治疗方法,根据接受的治疗将患者分为放疗组(n=23)与未放疗组(n=24);根据移植前是否有髓外浸润及移植后是否出现孤立髓外复发进行亚组分析,分为移植前放疗组与移植前未放疗组、移植后放疗组与移植后未放疗组;根据中枢神经系统白血病(CNSL)患者治疗方法分为鞘内注射组(n=12)与鞘内注射联合放疗组(n=13)。比较放疗、化疗等方法治疗后患者的局部缓解情况、生存时间及毒副反应。结果急性白血病合并髓外浸润患者中放疗组总生存时间(OS)优于未放疗组(中位OS:706 d vs.151 d,P=0.015);亚组分析显示移植前放疗组OS优于移植前未放疗组(中位OS:592 d vs.386 d,P=0.035);CNSL鞘内注射联合放疗组OS优于鞘内注射组(中位OS:547 d vs.388 d,P=0.045)。放疗组无事件生存时间(EFS)优于未放疗组(中位EFS:175 d vs.50 d,P=0.005)。COX比例风险模型显示,放疗和未放疗对急性白血病合并髓外浸润患者的OS有明显影响,移植前未放疗组相比移植前放疗组死亡风险增加了2.231倍(HR=3.231,95%CI:1.021~10.227,P=0.046)。相比未放疗组,放疗组局部缓解率更高,且具有更低的血液学毒性反应、感染和出血风险。结论放射治疗可迅速缓解急性白血病合并髓外浸润的局部症状,延长这部分患者的生存时间,且血液学毒性反应、感染和出血风险较低。

Immune thrombocytopenia (ITP) is a chronic disease resulting from increased platelet destruction and impaired platelet production. Secondary ITP can be a manifestation of chronic graft-versus-host disease (GVHD) and represent a lymphoproliferative disorder. A boy with chronic graft-versus-host disease after cord blood stem cell transplantation who had severe refractory immune-mediated thrombocytopenia received infusion of rituximab weekly, 375 mg/m2, for 4 weeks. Platelets count of the patient was recovered, and rituximab was well tolerated with no severe toxicity observed during treatment.
