简介:摘要目的探讨PRL-3在胃癌发生中的意义及与胃癌临床病理特征的关系。方法采用免疫组织化学PV-9000法检测80例胃癌组织中PRL-3的表达情况。每例标本均含原发癌组织和癌旁组织,对照组的癌旁组织为距离癌组织5cm以上。患者术前均未接受任何抗肿瘤治疗。结果胃癌组织中PRL-3阳性表达率高于癌旁组织的阳性表达率(P<0.05),其表达水平和浸润深度、淋巴结转移、TNM分期有关(P均<0.05)。结论PRL-3的表达与胃癌侵袭转移关系较密切,其表达水平在一定程度上提示胃癌的转移潜能,PRL-3可作为胃癌诊断、治疗及预后判断过程中的一种较有价值的病理学指标。

简介:目的考察3~5岁听障儿童的气质特点及其影响因素,为康复训练提供参考依据。方法选取111名3~5岁听障儿童,采用3~7岁儿童气质问卷施测。结果3~5岁听障儿童在气质各维度上的表现倾向不同(P〈0.05),适应度维度得分最高,其次为趋避性、心境、注意分散度和规律性,注意力持久性和反应阂得分最低。儿童性别、主要照顾人及其受教育水平、职业、家庭结构对听障儿童气质的多个维度具有显著影响(P〈0.05),主要表现在反应强度、注意力持久性、规律性、注意分散度、活动量、心境和适应度维度;助听设备和康复时间对听障儿童气质特点影响不明显(P〉0.05)。结论3~5岁听障儿童的气质受家庭、社会环境等多方面因素影响,但在具体特征上有其独特性。

简介:摘要目的分析高危儿2-3岁步行周期中踝关节异常姿势情况。方法运用直接目测观察法结合间接录像观察法对我院高危儿门诊随访的160例2-3岁小儿进行步态分析,重点观察踝关节在步行周期中的运动姿势。并根据一岁前是否曾因运动落后或姿势异常进行过早期干预分为干预组(90例),未进行过康复训练的患儿为空白组(70例),对两组患儿踝关节异常姿势发生率进行比较。结果①160例小儿在步行周期中出现踝关节姿势异常的总发生率占15%,干预组姿势异常发生率(10.0%)较空白组(21.4%)显著降低,两者差异具有统计学意义(P<0.05);②其中首次着地前脚掌着地占3.7%,站立相足外翻占5.6%,站立相足内翻占1.3%,迈步初期足趾拖地占3.1%,迈步相过度跖屈占1.3%;③干预组高危儿踝关节姿势异常最主要表现为“首次着地前脚掌着地”,空白组高危儿踝关节姿势异常最主要表现为“站立相足外翻”。结论高危儿在2-3岁独走步行周期中踝关节姿势异常发生率较高,早期干预能有效的降低踝关节姿势异常的发生率,因此在高危儿随访门诊中应加强小儿步态的随访监测,对异常姿势给予及时康复干预。
