理疗在麻风康复中的应用

理疗可用于急性神经炎、麻风反应和早期瘫痪或全瘫，以及术前准备和术后功能训练。 急性神经炎疼痛严重，如不迅速控制，受侵神经会发生永久性损害。治疗目的是要早期尽快使炎症消退和减轻疼痛。最好是用药物治疗和理疗相结合。热疗和制动可减轻疼痛，促进炎症消退。     

化疗对卵巢癌患者红细胞免疫功能的影响

本文用红细胞Ｃ３ｂ受体花结率（ＲＣ３ｂＲＲ）红细胞免疫复合物花结率（ＲＩＣＲ）、红细胞肿瘤花结率（ＥＴＲ）测定外周血红细胞免疫功能对２０例接受化疗的卵巢恶性肿瘤患者进行动态观察。结果表明，与化疗前相比，化疗第１疗程后，机体红细胞免疫功能无明显变化，第２疗程后开始有轻度损伤，以后随着疗程的增加，红细胞免疫功能有逐渐下降趋势，表现为ＲＣ３ｂＲＲ和Ｅ－ＴＲ降低、ＲＩＣＲ升高。提示化疗可能抑制机体红细胞免疫功能；卵巢癌患者进行化疗的同时，宜加用免疫调节剂。

39例非典型心肌梗死的护理体会

有些心肌梗死临床症状往往不典型，并且差别较大，尤其是老年人非致命性心肌梗死约有1／4不被病人发现，误诊、漏诊率较高。因此，对于非典型心肌梗死的及时诊治和护理十分重要，现将我们对39例非典型心肌梗死患者的观察和护理体会报告如下。     

64层螺旋CT冠状动脉成像定位像CT值与管电流关系的研究

Objective To characterize the association between the mean CT value on a scout view and the dependent mA selection method, and to evaluate the clinical value of a mA selection method based on scout view mean CT value in obtaining individualized scan protocol and consistent image quality for patient population on 64-row MSCT CT coronary angiography (CTCA).Methods One hundred patients (group A) underwent CCTA consecutively using standard protocol with a fixed mA.The mean CT value of a fixed ROI (region of interest) from the scout AP view and the CTCA image noise (standard deviation on the root of ascending aorta) were measured.The correlation between CT values and noise was studied establish a formula and a list to determine the required mA for obtaining a consistent CTCA image noise based on the measured SV CT value.Another 100 patients (group B) were scanned using the same parameters as group A except the mA and the CT value was also measured.The mA was determined by the list established previously.The CTCA image quality (IQ) as well as the image noise (IN) and the effective dose (ED) from the two groups were statistically analyzed using t-test.The CT findings for the 32 patients in the group B were also compared with the selective coronary angiography (SCA) results.The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of CCTA for detection of significant stenosis were obtained.Results The formula between the required mA and the CT value was : XmA=FmA×[(K1×CTscout + C1)/INa]2.The CCTA images in B group had statistically higher IN (27.66±2.57,22.22±4.17,t=11.33, P=0.000), but no statistical difference between IQ scores for the two groups (3.29±0.66,3.37±0.67,t=0.009, P=0.990), and ED[(8.72±2.51) versus (12.53±0.90) mSv]was 30% lower for the B group (P<0.01).For the 32 patients in the B group who had SCA, the CCTA sensitivity, specificity, positive predictive value, negative predictive value, and stenosis detection accuracy were 94.92% (56/59), 92.13% (82/89) ,88.89% (56/63) ,96.47% (82/85) and 93.24% (138/148) wspectively for stenosis greater than 50%.Conclusion The mA selection method based on the SV CT value for CCTA in 64-row MSCT provides individualized protocol to obtain consistent image quality and to optimize dose delivery to patients.     

卵巢肿瘤患者红细胞免疫功能及超氧化物歧化酶的初步研究

对２２例正常妇女、２３例卵巢恶性肿瘤患者和２７例卵巢良性肿瘤患者进行红细胞Ｃ３ｂ受体花环率（ＲＢＣ－Ｃ３ｂＲ）、红细胞免疫复合物花环率（ＲＩＣＲ）、红细胞肿瘤花环率（ＲＢＣ－ＣａＲ）和超氧化物歧化酶（ＳＯＤ）活性的测定。结果表明：卵巢恶性肿瘤组ＲＢＣ－Ｃ３ｂＲ和ＲＢＣ－ＣａＲ明显低于正常人和良性组（Ｐ＜０．０１），而ＲＩＣＲ较良性组上升（Ｐ＜０．００１），卵巢恶性肿瘤组ＳＯＤ活性亦明显低于正常人和良性组（Ｐ＜０．００１）。提示：卵巢恶性肿瘤患者的红细胞免疫功能低下，ＳＯＤ活性降低。本研究还对红细胞免疫和ＳＯＤ的相关性进行了分析和探讨。     

卵巢恶性肿瘤诊断的现状

卵巢恶性肿瘤,种类繁多,至今尚无切实可行的早期诊断方法。确诊时,70％以上的患者已届晚期,故虽经数十年努力,其5年存活率一般仍在30％左右。而近年来卵巢恶性肿瘤的发生率国内外均有上升趋势,其死亡率之高,已超过子宫颈与子宫体恶性肿瘤之和,为此,作者就当前国内外对卵巢恶肿瘤的诊断现状作一综述。 病史及体征 由于卵巢恶性肿瘤在早期常无典型症状与体征,故检查不易发现以致误诊。但基本的临床病史询问与常规全身及妇科检查极为重要,有可能从中发现早期卵巢癌的蛛丝马迹,如好发年龄在40～
