简介:目的评价芬太尼透皮贴剂对中重度癌痛患者3日内镇痛的临床疗效及安全性。方法通过开放性多中心临床观察,将234例中重度癌痛患者分为两组:口服盐酸吗啡片滴定后转换为芬太尼透皮贴剂组(A组);芬太尼透皮贴剂直接滴定组(B组)。评估治疗前和芬太尼使用3天后患者的疼痛程度、生活质量及不良反应。疼痛减轻程度大于初始评估50%以上者判定为疼痛治疗有效。结果A组和B组疼痛总缓解率分别为87%(87/100)和85.1%(114/134),P=0.675,治疗前和治疗3日后A组患者NRS均值分别为6.55±0.58、2.53±0.93(P=0.000);B组患者NRS均值分别为6.83±0.81,2.33±1.05(P=0.000);A组和B组芬太尼透皮贴剂初始剂量均值分别为(59.0±78.5)μg/h和(45.4±77.0)μg/h,使用3日后调整的剂量均值分别为(65.6±78.9)μg/h和(57.9±81.3)μg/h,组间比较差异无统计学意义;3日内A组对芬太尼进行剂量调整的患者占31%(31/100),明显低于B组60.4%(81/134)(P=0.000);A组1周内出现爆发痛的比例(19%,19/100)亦明显低于B组(52.2%,70/134)(P=0.000)。A、B两组出现的便秘、恶心呕吐、嗜睡、皮肤瘙痒、尿潴留等不良反应差异无统计学意义。A、B两组的生活质量(qualityoflife,QOL)评分在用药3日后均明显高于治疗前(P=0.000),组间比较差异无统计学意义。结论芬太尼透皮贴剂3日内镇痛效果满意,直接滴定治疗安全有效,但存在爆发痛风险,需调整治疗剂量;推荐即释吗啡滴定联合芬太尼透皮贴剂作为中重度癌痛治疗的首选组合之一。
简介:目的分析本院1987~1991年及2004~2006年两个阶段住院治疗的八大类恶性肿瘤病人的病种构成,为本省的肿瘤防治提供科学依据。方法统计分析和比较1987~1991年及2004~2006年两个阶段在本院住院治疗的八大类恶性肿瘤病例的病种构成比及顺位变化。结果结果显示:①1987~1991年住院病例中前四位恶性肿瘤分别是鼻咽癌、肺癌、宫颈癌和乳腺癌,2004~2006年住院病例中前四位恶性肿瘤为肺癌、乳腺癌、宫颈癌、鼻咽癌;②两个阶段相比较,鼻咽癌、食道癌下降明显(P〈0.01),子宫颈癌、女性乳腺癌、大肠癌、肝癌、胃癌上升明显(P〈0.01);③宫颈癌的平均住院年龄提前近5a(P〈0.05)。结论肺癌、乳腺癌、宫颈癌、鼻咽癌已经成为湖南省肿瘤医院住院病人中的主要恶性肿瘤,需引起肿瘤防治部门的重视。

简介:目的探讨甲状旁腺功能亢进(hyperparathyroidism,PHPT)导致骨病的诊疗策略。方法回顾本中心诊治的26例PHPT骨病患者的临床资料,其中男6例,女20例,年龄13-83岁,平均50岁。26例症状均有骨痛,其中6例合并活动障碍,5例合并乏力。结果术前,本组26例中23例血钙均高于正常,为2.65-l4.28mmol/L,平均3.00mmol/L。26例中,16例血磷正常,10例均低于正常(0.53-0.77mmol/L,平均0.61mmol/L)。26例甲状旁腺素(PTH)均高于正常(105-2361ng/L,平均651.88ng/L),15例行X线平片检查,3例无明显异常;12例呈骨密度减低,5例出现骨皮质吸收。所有患者均转入普外科行甲状旁腺腺瘤切除术,1例术后行刮除植骨内固定术,1例术后骨折行切开复位内固定。术后随访半年至2年,1例术后发生骨折,其余25例均无骨折发生,25例骨痛明显改善,VAS评分均〈3分,骨痛明显改善所需时间为3天至1年半。结论对骨痛、病理性骨折的患者,应加以怀疑PHPT的可能,完善并密切关注血钙及PTH检查结果,结合甲状旁腺超声及骨骼相关的影像学检查,可确诊此病。经普外科切除甲状旁腺腺瘤后,长期随访此病预后较好,并发症少。

简介:目的:探讨14—3—3β基因(酪氨酸3-加单氧矽色氨酸5-加单氧酶激活蛋白基因)对卡波氏肉瘤(Kaposigsarcoma,KS)细胞迁移的影响。方法:采用脂质体法将14—3—3β基因稳定转染入BCBL—1(HHV-8positiveandEBVnegativehumanBcells)细胞,Western—Blot检测14—3—3β蛋白的表达,最后利用Transwell法分析14—3—3β基因对BCBL-1细胞迁移的影响(设立空载体组和阴性对照组)。结果:pcDNA3.1/myc—His(-)A-14—3—3β组细胞迁移数目明显高于pcDNA3.1/myc—His(-)A组和阴性对照组,差异具有统计学意义(P〈0.05);pcDNA3.1/myc—His(-)A组和阴性对照组细胞迁移数目相比差异无统计学意义(P〉0.05)。结论:14—3—3β基因能促进KS细胞的迁移。
