    • 摘要: 目的 探讨芳香化酶(CYP19)基因型与等位基因突变对预测子宫内膜异位症(EMS)患者术后复发的预测价值.方法 随机抽取复发病例与无复发病例各40例,分为复发组40例和无复发组40例.比较两组患者年龄、病程、r-AFS分期、病灶直径、手术方式和有无CYP19基因以及COMT等位基因突变情况,多因素Logistic回归模型分析影响EMS患者术后复发的危险因素.结果 复发组r-AFS分期Ⅲ期、病灶直径≥3 cm、保守性手术以及CYP19基因突变率高于无复发组,且差异具有统计学意义(P<0.05).经多因素Logistic回归性分析证实,r-AFS分期Ⅲ期、病灶直径、手术方式和CYP19基因突变为影响EMS患者术后复发的危险因素(P<0.05).结论 CYP19基因突变以及r-AFS分期Ⅲ期、病灶直径、手术方式是EMS患者术后复发的危险因素,在临床诊治中应当受到临床医师的关注,对有复发高危因素的患者应慎重选择手术方式且需加强术后预防复发治疗.

    • 摘要: Objective To explore the correlation between rs4680 polymorphic site of catechol-O-methyl transferase (COMT)gene and postoperative pain so as to provide theoretical evidence for individualized medicine.Methods A total of eighty-three patients [aging 29-58,American Society of Anesthesiologists (ASA) Ⅰ or Ⅱ] scheduled for mastectomy under general anesthesia was selected.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was adopted to identify their genotype of rs4680 polymorphic site of COMT.The patients were divided as a wild-type group (Val/Val,VV,n=51),a hybrid subtype group (Val/Met,VM,n=23) and a mutation-type group (Met/Met,MM,n=9).Then the tertiary structures of COMT protein before and after mutation were predicted through homology modeling and the physicochemical property of the protein was analyzed.Preoperative anesthesia was conducted by intravenous-inhalation combined anesthesia and postoperative anesthesia by patient controlled intravenous analgesia (PCIA).The number of effective and ineffective compressions of the analgesic pump within 24 h was recorded.Patients' pain was assessed 2,4,8 h and 24 h after operation by the Numerical Rating Scale (NRS) and then its correlation with different genotypes was analyzed.Results The mutation of rs4680 polymorphic site of COMT has no significant effects on tertiary structures of COMT protein but it affected the physicochemical property of COMT protein.MM patients showed remarkably more PCIA press time than VV and VM patients 24 h after surgery (P<0.05).MM patients presented markedly more PCIA effective press time than VV patients (P<0.05).There was no significant difference in NRS score between the three genotypes at each postoperative point.Conclusions Single polymorphic site rs4680 may have little influence on individual difference of postoperative pain for patient with breast cancer.%目的 探讨儿茶酚氧位甲基转移酶(catechol-O-methyl transferase,COMT)基因rs4680多态位点与术后疼痛的关系,为个性化用药提供理论依据. 方法 择期全身麻醉行乳腺癌切除手术患者83例,年龄29~58岁,ASA分级Ⅰ、Ⅱ级.采用聚合酶链反应-限制性片段长度多态性技术(polymerase chain reaction-restriction fragment length polymorphism,PCR-RFLP)对83例患者COMT基因rs4680位点进行基因型鉴定,根据基因类型将患者分为野生型Val/Val(VV,51例)、杂合型Val/Met(VM,23例)和突变型Met/Met(MM,9例);采用同源建模对突变前后蛋白质的三级结构进行预测,并对蛋白理化性质进行分析.采用统一的静吸复合麻醉方案进行术前麻醉,术后行患者自控静脉镇痛(patient controlled intravenous analgesia,PCIA),记录24h内镇痛泵的有效及无效按压次数,并用疼痛数字评分法(Numerical Rating Scale,NRS)评估不同基因型术后2、4、8、24h疼痛情况.结果 COMT基因rs4680突变对蛋白三级结构无明显改变,但对蛋白的部分理化性质有所影响.术后24 h内MM患者PCIA总按压次数明显高于VV患者和VM患者(P<0.05),MM患者PCIA有效按压次数明显高于VV患者(P<0.05),但3种基因型患者PCIA按压有效率差异无统计学意义(乃0.05).术后各时点3种基因型患者NRS评分比较,差异均无统计学意义(P>0.05). 结论 COMT基因单个多态位点rs4680可能对乳腺癌患者术后疼痛的个体化差异影响不大.

    • 摘要: Objective To observe the expression of catechol-O-methyltransferase (COMT) in inferior colliculus and auditory cortex of guinea pigs with age-related hearing loss(AHL) induced by D-galactose,so as to explore the possible mechanism of electroacupuncture(EA) underlying preventing AHL.Methods Thirty 3-month-old guinea pigs were randomly divided into control group,model group and EA group(n =10 in each group),and ten 18-month-old guinea pigs were allocated as elderly group.The AHL model was established by subcutaneous injection of D-galactose.EA was applied to bilateral "Yifeng" (SJ 17) and "Tinggong"(SI 19) for 15 min in the EA group while modeling,once daily for 6 weeks.After treatment,the latency of auditory brainstem response(ABR) Ⅲ wave was measured by a braín-stem evoked potentiometer.The expressions of COMT in the inferior colliculus and auditory cortex were detected by Western blot.Results Compared with the control group,the latencies of ABR Ⅲ wave were significantly prolonged and the expressions of COMT in the inferior colliculus and auditory cortex were significantly decreased in the model group and the elderly group(P<0.05).After the treatment,the latency of ABR Ⅲ wave was significantly shortened and the expressions of COMT in the inferior colliculus and auditory cortex were significantly increased in the EA group in comparison with the model group (P<0.05).Conclusion EA at "Yifeng" (SJ 17) and "Tinggong" (SI 19) can improve the hearing of age-related deafness in guinea pigs,which may contribute to its effect in up-regulating the expression of COMT in the inferior colliculus and auditory cortex.%目的:观察D-半乳糖所致的年龄相关性聋(AHL)豚鼠下丘和听皮层儿茶酚氧位甲基转移酶(COMT)表达,探讨电针防治AHL的可能机制.方法:3月龄豚鼠随机分为对照组、模型组、电针组,每组10只,另10只18月龄豚鼠为老年组.以D-半乳糖颈背部皮下注射复制AHL模型.电针组造模同时予以电针“翳风”穴和“听宫”穴,每日1次,每次15 min,共6周.治疗后测定各组听性脑干反应(ABR)Ⅲ波潜伏期,Western blot法检测各组下丘及听皮层COMT的表达.结果:与对照组比较,模型组和老年组ABRⅢ波潜伏期显著延长(P<0.05);与模型组比较,电针组ABRⅢ波潜伏期显著缩短(P<0.05).与对照组比较,模型组和老年组下丘和听皮层COMT表达显著降低(P<0.05);与模型组比较,电针组下丘和听皮层COMT表达显著增加(P<0.05).结论:电针“翳风”穴和“听宫”穴能改善AHL豚鼠的听力,其作用机制可能与增加下丘和听皮层COMT表达有关.

    • 摘要: 利用 RACE (rapid amplification of cDNA ends)技术,克隆了凡纳滨对虾儿茶酚-氧位-甲基转移酶(catechol-O -methyltransferase,COMT)基因 cDNA 序列。该基因(LvCOMT)cDNA 全长910 bp(GenBank 登录号JQ345478),含有666 bp的开放阅读框(ORF),编码221个氨基酸,理论分子量74.9 ku,等电点4.98。经软件分析,该成熟肽有12个磷酸化的氨基酸位点,不具信号肽,推测凡纳滨对虾COMT基因可能是依赖12个可能的氨基酸发生可逆的磷酸化反应来进行调控作用。LvCOMT基因与斑节对虾、中国明对虾的氧位-甲基转移酶具有高度相似性,系统进化分析表明,LvCOMT在亲缘关系上更接近于哺乳动物的儿茶酚-氧位-甲基转移酶。应用RQ-PCR分析COMT在凡纳滨对虾中的组织特异性分布,结果显示COMT在肝胰腺组织中表达量最高,在鳃中的表达量最低。

    • 摘要: 儿茶酚氧位甲基转移酶(COMT)是内源基因表达的二相代谢酶,由22号染色体表达.主要将S-腺苷甲硫氨酸上的甲基转移至底物的羟基上,使底物的一个羟基甲基化.COMT在体内的主要作用是代谢儿茶酚类的化合物,例如:多巴胺、肾上腺素、去甲肾上腺素、雌二醇等化合物,此外还能代谢体外通过饮食及药物摄入的儿茶酚类化合物.由于COMT在体内与化合物的代谢密切相关,COMT代谢失常能够引起很多疾病或者罹患疾病的风险增加,例如:帕金森病、精神分裂症、乳腺癌等疾病.本综述通过阐述COMT代谢紊乱引起的疾病尝试说明COMT与其相关疾病之间的联系,旨在能够对COMT代谢相关疾病提供有效的治疗方法.

    • 摘要: 目的::对多巴胺代谢系统儿茶酚氧位甲基转移酶( COMT) Val108/158Met同脑卒中后抑郁( PSD)的相关性进行探究。方法:择取过去两年(2014.5至2016.5)在我院神经内科接受治疗的80例PSD患者为观察组,另择取脑卒中后未出现抑郁的80例患者为对照组。采取聚合酶链式反应-限制性片段长度多态性技术(PCR-RFLP)对PSD患者的COMT以及多巴胺转运体(DAT)的40bp的可变数目串联重复多态(VNTR)位点的多态性进行分析并探讨其相关性。结果:同对照组相比,观察组患者COMT等位基因以及基因型分布均有明显差异(P0.05),无统计学意义。结论:脑卒中后抑郁患者的发病与患者COMTVal108/158Met的基因多态性有着明显的相关性,而与患者体内DAT40bp VNTR基因的多态性则无关联。

Data suggest that genetic factors may play a substantial role for the etiology of the behavior. Among the particular gene polymorphisms that have been considered to be involved in vio-lence behavior, the catechol-O-methyltransferase (COMT) gene had been the focus of recent research. This article reviews the association research between COMT gene and violence behavior in patients with schizophrenia in several aspects: SNP polymorphism of COMT Val158Met and COMT Ala72Ser, haplo-type of COMT gene and DNA methylation of promoter region of COMT gene. The genetic research di-rection is presented for patients with schizophrenia.
