目的提高对多发性骨髓瘤(MM)髓外皮肤和乳腺浸润的认识。方法回顾性分析2021年3月青岛大学附属医院收治的1例MM髓外皮肤和乳腺浸润患者的临床特点和诊治经过,并复习文献。结果患者为64岁女性,因腰背痛就诊,经病理活组织检查确诊MM。给予1个疗程VTD(硼替佐米+沙利度胺+地塞米松)方案诱导治疗,肾功能恢复后给予2个疗程VRD(硼替佐米+来那度胺+地塞米松)方案诱导化疗。VRD方案第4个疗程第1次用药后患者因情绪原因于家中自行划伤左手手腕,遂于当地医院急诊就诊。后患者手腕伤口愈合、情绪好转后,于2021年8月再次入院,查体发现左手腕部皮肤异常增生,同时伴乳腺肿块。结合病史及免疫组织化学结果,综合考虑为MM髓外皮肤和乳腺浸润。予BPD(苯达莫司汀+泊马度胺+地塞米松)方案治疗2个疗程,患者手腕肿物及左乳肿物明显缩小,但再次出现疾病进展,患者最终放弃治疗后死亡。结论MM髓外皮肤和乳腺浸润相对罕见,治疗效果和预后极差。建议给予新一代药物组合方案或联合细胞毒性药物进行强化诱导治疗,为造血干细胞移植治疗或嵌合抗原受体T细胞免疫治疗创造条件。

Fast electron-hole recombination issues during titanium dioxide(TiO_(2))photocatalysis limit its application in preventing bacterial infection during bone defect *** this study,TiO_(2)@reduced graphene oxide(rGO)composites were synthesized using a hydrothermal method in which rGO,which possesses very high electrical conductivity,promotes the separation of photoelectron-hole pairs of TiO_(2),thus improving the efficiency of photocatalytic production of reactive oxygen species(ROS).Subsequently,TiO_(2)@rGO composites were introduced into poly-L-lactic acid(PLLA)to prepare bone scaffolds with photocatalytic antibacterial function via selective laser *** results showed that TiO_(2)grew on the surface of rGO and formed a covalent bond connection(Ti-O-C)with rGO.A decreased electrochemical impedance of TiO_(2)@rGO composites was observed,and the transient photocurrent intensity increased from 0.05 to 0.5μA/cm^(2).Analysis of electron spin resonance found that the photocatalytic products of TiO_(2)were·OH and·O^(2-),two kinds of ROS capable of killing bacteria via disrupting the structure of the bacterial membrane in *** experiments showed that the PLLA/TiO_(2)@rGO scaffolds had good antibacterial properties against Escherichia coli and Staphylococcus ***,we report that these scaffolds exhibited both enhanced mechanical properties due to the addition of TiO_(2)@rGO as a reinforcement material and good biocompatibility during cell proliferation.

为明确生产栽培小麦品种对玉米象Sitophilus zeamais(Motschulsky)的抗性机制,采用选择性和非选择性试验法系统评估了9个小麦品种对玉米象的抗性,并分析了小麦籽粒营养物质和次生物质含量与其抗性的关系。结果显示,不同小麦品种对玉米象的抗性存在显著差异,其中陕麦139和西农88的不选择性和抗生性较弱,小偃22、周麦16和周麦11较强;玉米象成虫对西农165选择性最强,虫口数为152.00头,而卵至子代成虫发育历期最长,为35.06 d,子代成虫数、重量损失率和敏感系数均较低,分别为19.67头、5.37%和8.30;对周麦18选择性最差,敏感性居中。玉米象成虫对不同小麦品种的选择性与各物质含量,以及总酚、蛋白质含量与各抗性指标均无显著相关性,但阿魏酸含量与子代成虫数、敏感系数及重量损失率显著负相关;可溶性糖含量与子代成虫数、敏感系数及重量损失率显著正相关,与卵至子代成虫发育历期显著负相关。表明小麦品种对玉米象的抗生性与其籽粒中阿魏酸和可溶性糖含量相关,阿魏酸含量越高、可溶性糖含量越低,小麦对玉米象的抗性越强。
