目的探讨重组人血管内皮抑素(恩度)联合放疗对人鼻咽癌细胞株1(CNE1)鼻咽癌裸鼠移植瘤的生长及血管内皮生长因子(VEGF)、基质金属蛋白酶-2(MMP-2)和基质金属蛋白酶-9(MMP-9)mRNA表达的影响。方法建立人鼻咽癌细胞裸鼠模型,成瘤后随机分为4组,对照组、恩度组、放疗组和恩度+放疗联合组,分别进行恩度与放疗干预,观察各组移植瘤的生长速度和瘤体大小的变化。4周后处死裸鼠摘取瘤体,应用RT-PCR检测各组瘤体组织中的VECF、MMP-2和MMP-9 mRNA的表达变化。结果联合组对鼻咽癌移植瘤的生长有显著抑制作用,且明显强于其他三组(均P〈0.05);联合组中VECF、MMP-2和MMP-9的表达与另外三组相比均显著下调(均P〈0.05);VEGF与MMP-2及MMP-9的表达呈正相关(均P〈0.01)。结论恩度联合放疗能明显抑制CNE1鼻咽癌移植瘤的生长,恩度对鼻咽癌裸鼠抑制瘤具有放疗增敏作用,这种作用可能与VEGF、MMP-2和MMP-9表达下调有关。  相似文献

目的:探讨以β1整合素反义寡核苷酸(ASODN)治疗人卵巢癌裸鼠皮下移植瘤的可行性.方法:常规体外培养SKOV3细胞,采用皮下注射法建立移植瘤裸鼠动物模型.32只荷瘤鼠随机分为ASODN组(A组)、ASODN联合顺铂(DDP)组(A+D组)、DDP组和0.9%氯化钠注射液对照组(NS组),每组8只,分组给药.以脂质体包裹的β1整合素ASODN直接移植瘤内注射,观察肿瘤生长情况,测瘤体积并计算抑瘤率.采用反转录-聚合酶链反应(RT-PCR)和免疫组织化学方法分别检测β1整合素mRNA的表达.结果:A组肿瘤体积和抑瘤率分别为(316.10 ±21.77) mm3和48.15%,与NS组比较抑瘤率较高,肿瘤生长缓慢(P<0.01).而A+D组肿瘤体积和抑瘤率分别为(178.70±40.67) mm3和70.37%,与DDP组、A组及NS组差异均有统计学意义(P <0.05 ~P<0.01).RT-PCR和免疫组织化学检测,A组和A+D组肿瘤组织中β1整合素mRNA的表达均明显下调(P<0.01).结论:单用β1整合素ASDON或联用DDP均可有效抑制人卵巢癌裸鼠皮下移植瘤组织的生长,可能与其特异性下调β1整合素基因表达有关.特异性靶向β1整合素ASODN可用于卵巢癌的辅助治疗.  相似文献

目的评估表皮生长因子(EGFR)抑制剂AG1478与顺铂(CDDP)联合应用对人脑多形性胶质母细胞瘤(glioblastoma multiforme,GBM)裸小鼠脑原位移植瘤的疗效。方法人脑GBM裸小鼠脑内原位移植模型建立后第3天,将40只小鼠随机分为4组,每组10只,各组小鼠每次分别应用AG1478(25mg/kg)、CDDP(3mg/kg)、AG1478+CDDP(25mg/kg+3mg/kg)及PBS(0.1ml/只)。上述药物均腹腔注射,每2天1次,共4次,用药后观察各组荷瘤鼠生存期。重复上述实验步骤,肿瘤移植后14d处死各组小鼠取脑,HE染色后观察各组移植瘤形态及体积变化;EnVision法检测移植瘤中EGFRⅧ、磷酸化EGFRⅧ(P-EGFRⅧ)的表达及增殖活性变化;TUNEL法检测移植瘤细胞凋亡变化。结果与对照组[(19.4±0.6)d]比较,单用CDDP或AG1478荷瘤鼠生存期分别为(20.7±0.4)d和(20.8±0.6)d(P〉0.05),而CDDP+AG1478组荷瘤鼠生存期为(33.6±0.9)d(P〈0.05);CDDP+AG1478能明显减小移植瘤体积,降低增殖活性及促进肿瘤细胞凋亡,而单独用药对此效果不明显。结论AG1478与CDDP联合应用有协同的抗肿瘤疗效,这为EGFR抑制剂和常规化疗药物联合治疗恶性胶质瘤提供了实验依据。  相似文献

目的研究凋亡抑制基因Survivin的表达与EGCG对鼻咽癌CNE-2裸鼠移植瘤放疗增敏作用的关系。方法将低分化鼻咽癌细胞CNE-2接种于4~6周龄的雌性裸鼠皮下,待移植瘤生长至4~6 mm时,随机分为4组,分别采用NS、EGCG[50 mg/(kg.w)]、放疗(15 Gy)、EGCG给药24 h后再行放疗等方法分别处理各组裸鼠,处理前后分别测量裸鼠移植瘤的短径、体积。21 d后处死裸鼠,取出肿瘤并称重,将肿瘤组织分成两份,分别用来进行病理切片TUNEL染色以及RT-PCR检测Survivin mRNR的表达。结果EGCG+放疗对裸鼠移植瘤的生长抑制最为明显,肿瘤生长抑制率为89.3%,消退率为40.0%。与对照组EGCG组、放疗组相比,EGCG+放疗组的凋亡指数均明显增加(P<0.05),同时,伴有Survivin mRNR的表达显著下降(P<0.05)。结论EGCG对鼻咽癌裸鼠移植瘤可能具有放疗增敏作用,这种作用可能与凋亡抑制基因Survivin的表达下调有关。  相似文献

目的研究HIF-1α、EGFR、Caspase-3在鼻咽癌中的表达及其与鼻咽癌放射敏感性的关系。方法采用免疫组化S-P法检测28例鼻咽癌和25例鼻咽癌放疗后复发组织中HIF-1α、EGFR及Caspase-3的表达,RT-PCR检测YC-1对鼻咽癌细胞CNE-2Z中EGFRmRNA表达的影响。结果在鼻咽癌放疗后复发组织中HIF-1α和EGFR的阳性率均高于鼻咽癌组(P〈0.05);Caspase-3的阳性率低于鼻咽癌组(P〉0.05)。Spearman相关分析显示鼻咽癌组织中HIF-1α与EGFR表达具有相关性(γ=0.387,P〈0.05),与Caspase-3表达无明显相关性。鼻咽癌放疗后复发组织中HIF-1α阳性表达鼻咽癌患者放疗后复发时间早于阴性表达患者,但差异无统计学意义(P〉0.05),HIF-1α与Caspase-3表达呈负相关(γ=-0.436,P〈0.05),与EGFR表达无明显相关性。YC-1抑制CNE-2Z细胞中EGFRmRNA的表达(P〈0.01)。结论 HIF-1α及EGFR表达与鼻咽癌放射敏感性有关,EGFR可能通过非HIF-1α依赖途径参与鼻咽癌放疗后复发。  相似文献

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.  相似文献

Radiotherapy and chemotherapy are the important modern medical therapies for malignant tumors,yet they can also bring about serious local and systemic toxic side reactions so to decrease the patient;'s life quality,manifested by a series of consumptive symptoms.Having engaged in the combined work of Chinese and western medicine for nearly 50 years,the research fellow Qiu Baoguo in Henan Provincial Academy of TCM has developed his unique views on the TCM study of consumptive syndromes.The author of this essay had once the fortune tO follow Dr.Qiu in clinic,and specially would like to introduce in the following Dr.Qiu's experience in treating consumptive syndromes after radio-chemotherapies for patients with malignant tumor.  相似文献

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.  相似文献

Evidence obtained from randomized controlled trials (RCTs) has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.  相似文献
