  因子分析结果
     (2) Construct validity of occupational stress inventory revised edition (OSI-R)was tested by structure equation model. Single factor analysis results showedthat every one item (or latent variables) of three questionnaires has a finevalidity, but some subitem’s factor loading was low. It implied that thesesubitems need be revised or verified further in other studies.
     2、利用结构方程模型对 OSI-R 量表的三份问卷进行构念效度评价,单因子分析结果提示构念效度总体较好,但某些变量的个别条目有待于进一步验证或进行修订。

Objective To evaluate changes of auditory brainstem response (ABR) and its role in monitoring auditory functions during the brainstem surgery Methods The data of 400 ABRs from 5 operations for removal of astrocytic glioma, cavernomas or dermoid from the brainstem were analyzed The changes in latencies, amplitudes and wavefroms were dynamically observed and statistically analyzed with t test and Factor analysis Results Surgical manipulations, such as stretching, separation and extrusion,...

Objective To evaluate changes of auditory brainstem response (ABR) and its role in monitoring auditory functions during the brainstem surgery Methods The data of 400 ABRs from 5 operations for removal of astrocytic glioma, cavernomas or dermoid from the brainstem were analyzed The changes in latencies, amplitudes and wavefroms were dynamically observed and statistically analyzed with t test and Factor analysis Results Surgical manipulations, such as stretching, separation and extrusion, induced the prolongation of ABR peaks and interpeak latencies of wavesⅠ, Ⅲ , Ⅴ The amplitudes of waves decreased Three out of 5 cases presented reversible changes in latencies and wave forms The dynamical analysis showed: The maximal variable range of latency(LMVD) was more than 11 30%,the maximal reversible degree of latency(LMRD) was more than 53 85%,the time of convalescent half value latency(LCHT) was around 8~40 min, AMVD was more than 40%, the AMRD was more than 200%, and the ACHT was around 5~40 min In 2 out of the 5 patients the postoperative ABR latencies kept prolonged, some postoperative waves were malformed and difficult to be identified, One case died, another lost consciousness, their LMRDs were less than 33 33% These findings suggested that surgical intervention had significant effects on the ABR latency ( P <0 01) Conclusion ABR offers a promise for sensitive detection of the brainstem function Its latency, amplitude and waveform show us dynamic changes of the brainstem status and can be used as an index during the operation on the brainstem and its adjacent region

目的 探索脑干肿瘤手术中听性脑干反应(auditory brainstem response,ABR) 变化规律及其监护作用。方法 对5 例脑干肿瘤手术患者,从术前、术中至术后进行了ABR的动态观察,对术中监护记录的400 余份ABR的潜伏期、振幅和波形分化的资料进行分析和统计学处理。结果 术中牵拉、分离、挤压均可引起ABRⅠ、Ⅲ和Ⅴ波潜伏期延长,振幅降低,波形分化差等改变,其中3 例动态变化指标好,呈可逆性变化,均康复出院。另2 例术后潜伏期持续延长、波形分化差,动态变化指标差,呈不可逆性变化,术后1 例死亡,1 例未苏醒。析因分析显示:手术操作对听性脑干诱发电位的影响有显著性意义( 方差分析,P< 0.01) 。结论 在脑干肿瘤手术中,ABR能敏感地反映脑干功能,潜伏期、振幅、波形及其动态变化均是术中可靠的观察指标。

目的:了解乳腺癌E-钙粘附素、连环素-α,-β的表达改变与转移及预后的关系。方法:采用免疫组织化学染色、病理组织学,对105例乳腺癌患者术后定期随访,统计学分析。结果:105例乳腺癌三种粘附分子组化染色减弱和消失频率为E-钙粘附素56%,连环素-α64%,连环素-β43%,与正常及非典型增生组差别明显,P值均小于0.001。单因素分析未能找到E-钙粘附素与转移及预后的联系,但证明连环素-α和-β表达下降分别与癌分化程度及与转移、预后相关,P<0.05和P<0.01。三种粘附分子中E-钙粘附素与连环素-α的表达有平行关系,双阳性组的转移率明显低于一种蛋白表达下降组,P<0.05。COX多因素分析三种粘附蛋白表达均未能成为独立影响乳腺癌预后的因素。结论:E-钙粘附素、连环素-α,-β表达的免疫组化反应在乳腺癌呈下降的总趋势,E-钙粘附素与连环素-α的表达有平行关系,双阳性者转移率明显低。在三者之中连环素-β表达下降与癌转移及病程进展有明显相关性,预后相对差。在考虑用细胞间粘附体系为判断乳腺癌预后指标时必须对该三种分子作综合检测。
