    • 摘要: 目的 探讨转录因子GATA结合蛋白4(GATA4)、微小RNA-195(miR-195)在恶性脑膜瘤组织中表达水平,分析其与预后的关系.方法 选取文昌市人民医院自2015年5月至2019年5月收治的110例恶性脑膜瘤患者,取脑膜瘤组织、瘤旁组织检测GATA4、miR-195表达情况,并分析不同GATA4、miR-195表达情况患者临床病理特征.通过COX单因素及多因素模型分析影响恶性脑膜瘤患者预后的危险因素.结果 脑膜瘤组织中GATA4阳性表达率高于瘤旁组织,miR-195表达量低于瘤旁组织,差异有统计学意义(P<0.05).GATA4阳性患者WHO病理Ⅲ级、颅外转移占比高于GATA4阴性患者,差异有统计学意义(P<0.05).miR-195高表达患者WHO病理Ⅲ级、颅外转移占比低于miR-195低表达患者,差异有统计学意义(P<0.05).COX多因素分析显示,WHO病理Ⅲ级、颅外转移、GATA4阳性是患者预后的危险因素,miR-195高表达是患者预后的保护性因素(P<0.05).结论 恶性脑膜瘤组织中转录因子GATA4以阳性表达为主,miR-195表达则明显下调,WHO病理Ⅲ级、颅外转移、GATA4阳性是患者预后的危险因素,miR-195高表达是患者预后的保护性因素.

    • 摘要: 目的探讨miR-497对恶性脑膜瘤细胞增殖的影响及作用机制。方法收集2019年1~9月手术切除的女性脑膜瘤组织标本10例,其中恶性脑膜瘤5例(WHO分级Ⅲ级),良性脑膜瘤5例(WHO分级Ⅰ级),采用RNA-seq法和qRT-PCR检测脂肪酸合成酶(FASN)mRNA和miR-497表达水平。体外培养恶性脑膜瘤细胞株IOMM-Lee细胞,设置空白组(不做任何处理)、miR-NC组(转染negative control质粒)、miR-497-m组(转染miR-497 mimics)和miR-497-i组(转染miR-497 inhibitor),MTT法检测细胞增殖能力,检测细胞上清液乳酸水平和细胞ATP含量,免疫印迹法检测细胞FASN蛋白表达水平。结果恶性脑膜瘤组织FASN mRNA水平明显高于良性脑膜瘤组织(P<0.05),而miR-497水平则明显低于良性脑膜瘤组织(P<0.05)。与空白组和miR-NC组相比,miR-497-m组细胞增殖能力、细胞上清液乳酸水平、细胞ATP含量以及FASN蛋白表达水平均明显降低(P<0.05);而miR-497-i组细胞增殖能力、细胞上清液乳酸水平、细胞ATP含量以及FASN蛋白表达水平均明显升高(P<0.05)。结论恶性脑膜瘤组织miR-497呈低表达,通过靶向促进FASN表达,提高肿瘤细胞内脂肪酸代谢水平,促进肿瘤细胞增殖。

    • 摘要: 作为一种常见的颅内原发性肿瘤,脑膜瘤在颅内原发肿瘤中占有较高的比重,其发病率可随年龄的增加而增加,在女性群体中更为常见。临床上将脑膜瘤分为两类,一类是良性的脑膜瘤,另一类则是恶性的脑膜瘤。其中,根据脑膜瘤的复发倾向及侵袭性,WHO又将良性脑膜瘤分为九种类型,将恶性脑膜瘤分为六种类型。二者之间进行比较,良性脑膜瘤占绝大多数,占比可达85%-90%。不管是良性脑膜瘤还是恶性脑膜瘤,如果未能采取有效的措施进行及时的救治,则会对患者的生活质量带来不良的影响,严重者还有可能危及生命安全。

    • 摘要: 目的 探讨影响恶性脑膜瘤(WHOⅢ级)术后复发的相关因素.方法 回顾性纳入2002年1月至2015年12月西南医科大学附属医院神经外科收治的24例恶性脑膜瘤患者.对其术后的复发情况进行随访,应用单因素Kaplan-Meier生存分析和多因素Cox回归分析判断影响恶性脑膜瘤复发的独立因素.结果 24例恶性脑膜瘤患者中,有17例(71%)复发.单因素Kaplan-Meier生存分析结果显示:年龄(P=0.009)、瘤周水肿程度(P=0.005)、肿瘤最大径(P =0.050)、侵袭性类型(P=0.011)和手术切除程度(P=0.002)具有判断恶性脑膜瘤术后复发的价值.但经多因素Cox回归分析后,剔除侵袭性类型(RR =0.699,95% CI:0.184 ~2.658,P=0.600)、瘤周水肿程度(RR=2.915,95% CI:0.881 ~9.648,P=0.080)和肿瘤最大径(PR=1.314,95%CI:0.250 ~6.921,P=0.747),仅有年龄(RR=4.379,95%CI:1.125 ~ 17.051,P=0.033)和肿瘤切除程度(RR=3.442,95%CI:1.314 ~9.016,P=0.012)是影响恶性脑膜瘤复发的独立危险因素,差异具有统计学意义.结论 恶性脑膜瘤的肿瘤侵袭性类型、瘤周水肿程度和肿瘤最大径可能影响患者肿瘤的复发;年龄和肿瘤切除程度是影响恶性脑膜瘤复发的独立危险因素.%Objective To investigate the factors related to postoperative recurrence of nalignant meningiomas (WHO grade of Ⅲ).Methods A total of 24 pathologically confirmed cases of nalignant meningionas admitted to Neurosurgery Department of Affiliated Hospital of Southwest Medical University between January 2002 to December 2015 were enaolled into this respective study.The patients were followed up for possible recurrence and the related factors were studied by using single factor Kaplan-Meier survival anadysis and multivariate Cox regression analysis.Results Seventeen (71 c%) of the 24 patients with malignant meningiomas relapsed.The analysis results on recurrent malignant meningiomas showed that age (P =0.009),peritumoral edema (P =0.005),tumor size (P =0.050),invasive type (P =0.011) and extent of surgical resection (P =0.002) had statistical significance in malignant meningioma recurrence.However,by nultivariate Cox regression analysis,excluding the invasive type (RR =0.699,95% CI:0.184-2.658,P =0.600),peritumoral edema (RR =2.915,95% CI:0.881-9.648,P =0.080) and tumor size (RR =1.314,95%CI:0.250-6.921,P =0.747),only the age (RR =4.379,95% CI:1.125-17.051,P=0.033) and degree of surgical resection (RR =3.442,95 % CI:1.314-9.016,P =0.012) had statistical significance.Conclusions The peritumoral edema degree,tumor invasive type and tumor size of malignant meningionas nay affect the patients' recurrence.Age and extent of resection seem to be independent factors in determining the recurrence of malignant neningiomas.

Methods Ten surgical specimens of highly suspected malignant meningioma were obtained with postoperative pathological confirmation. Primary malignant meningioma cells were cultured from the tissues using a modified method and passaged.After identification with cell immunofluorescence,the cultured cells were inoculated into the right parietal lobe of 6 nude mice using stereotaxic apparatus and also transplanted subcutaneously in another 6 nude mice. The nude mice were executed after 6 weeks, and HE staining and immunohistochmistry were used to detect tumor growth and the invasion of the adjacent brain tissues. Results The primary malignant meningioma cells were cultured successfully, and postoperative pathology reported anaplastic malignant meningioma. Cell immunofluorescence revealed positivity for vimentin and EMA in the cells,which showed a S-shaped growth curve in culture.Flow cytometry revealed a cell percentage in the Q3 area of(95.99±2.58)%.Six weeks after transplantation,tumor nodules occurred in the subcutaneous tumor group,and the nude mice bearing the in situ tumor showed obvious body weight loss.The xenografts in both groups contained a mean of (36±5.35)% cells expressing Ki-67,and the intracranial in situ tumor showed obvious invasion of the adjacent peripheral brain tissues.Conclusion We obtained stable primary cultures of malignant meningioma cells and successfully established a nude mouse model bearing in situ human malignant meningioma.
