室间隔缺损患者肺动脉压的多因素分析

本文对４３例经心导管证实的空间隔缺损患者进行了多因素逐步回归分析，发现在２３项临床参数中，对肺动脉压有显著影响的因素，依次为红细胞压积、周围血管征、空间隔缺损大小、心脏杂音强度、心胸比率（ｒ＝０．８０２８），并初步探讨了各因素对肺动脉压的影响机制，旨在能非创伤性地动态了解患者肺动脉压力，为临床工作提供参考依据。     

肉鸡对不同形态锰源的生物利用率研究

目的 :　研究肉仔鸡对不同形态锰源的相对生物学利用率。方法 :　将 62 4只 1日龄肉公鸡随机分为 1 3组 ,分别饲不添加锰的基础饲粮 (对照组 )或以不同锰化合物添加 60、1 2 0、1 80 mg/ kg锰的试验饲粮 2 1 d。结果 :　肉鸡生长性能各指标和腿病发生率以及肉鸡的跖骨灰锰含量、心肌细胞线粒体中 Mn SOD活性均未受到添加锰源以及锰源与锰水平互作的显著影响 ,但受到添加锰水平的显著影响。肉鸡心肌含锰量和 Mn SOD m RNA水平均未受到添加锰源与锰水平互作的显著影响 ,但受到添加锰源及添加锰水平的显著影响。其中中等和强络合强度有机锰源的生物学利用率明显高于无机硫酸锰和弱络合强度有机锰源。结论 :　中等和强络合强度的复合氨基酸锰对肉仔鸡的生物学利用率明显优于无机硫酸锰和弱络合强度的蛋氨酸锰     

年轻人冠状动脉壁平滑肌细胞的表型变化及其与巨噬细胞的关系——免疫组织化学研究

选用年轻人冠状动脉材料，免疫组织化学方法，观察了弥漫性内膜增厚、脂纹、动脉粥样硬化斑块中平滑肌细胞的免疫表型变化，并将这些变化同巨噬细胞进行了联系。结果表明，凡是有巨噬细胞浸润之处，不管何种病变，该处的平滑肌细胞便失去了相应抗体的反应性，但仍能被抗间叶细胞抗体所标记，提示平滑肌细胞已经发生表型转变。这一现象说明巨噬细胞在平滑肌细胞表型转变过程中起重要作用，有助于人们对动脉粥样硬化病变、冠脉成形术后再狭窄病变发生过程的认识。

组织多肽特异性抗原在乳腺癌中的临床研究

OBJECTIVE: To investigate the expression of serum tissue polypeptide-specific antigen (TPS) in breast cancer patients and its clinical value in such cases. METHODS: Altogether 160 subjects (90 patients with breast cancer, 40 with benign breast lesions, and 30 healthy subjects) were enrolled in this study. The serum TPS and CA153 levels were measured by ELISA in all the subjects. RESULTS: The levels and positivity rate of serum TPS and CA153 in breast cancer group were significantly higher than those in the normal subjects group and benign lesion group (P<0.01), and became even higher as the malignancy progressed. High serum TPS level was detected in the cancer patients in stage I. Serum TPS level was the most sensitive to bone metastasis of the malignancy, but its highest levels occurred in cases of lymphoid node metastasis (P<0.05). In patients who responded favorably to the treatment, serum TPS and CA153 levels were significantly reduced (P<0.05), but the reduction in TPS levels tended to be more obvious (P<0.05). CONCLUSION: Serum TPS can be used as a very useful and sensitive tumor marker in the diagnosis of breast cancer, especially in case of bone metastasis, and may be of great value in clinical decision-making and assessment of therapeutic effect.     

THE TREATMENT OF SPINAL CORD INJURY CASES BY MEANS OF SPINAL OMENTUM TRANSPOSITION

Omentum transposition to cervical spinal cord for the treatment of traumatic cervical spinal cord myelopathy.In treating spinal cord injury, the clinic of cervical spinal cord injury has to face the problems of tetraplegia and control of Respiration. The application of various kins of treatment include skull traction, laminectomy, intervebral bone graft fusion and omen turn spinal cord transposition. We have treated 10 cases in the period from June, 1986 to June, 1983. The discussion will focus on the Oinentum transposition to cervical spinal cord and the related problems of cervical spinal cord injury.     

Bilateral versus unilateral sudden sensorineural hearing loss.

OBJECTIVES: To analyze the clinical characteristics and treatment results between bilateral (bi-) and unilateral (uni-) sudden sensorineural hearing loss (SSNHL). STUDY DESIGN AND SETTING: A retrospective study. METHODS: Three hundred twenty-four patients with SSNHL were classified into two groups; simultaneous bi-SSNHL (n = 16) and uni-SSNHL (n = 308). We compared clinical characteristics, medical history, hearing level, and treatment results between the 2 groups. RESULTS: The incidence of bi-SSNHL was 4.9 percent of overall patients with SSNHL. Bi-SSNHL occurs more commonly in patients of older age, with preexisting diabetes mellitus, and lipid panel abnormalities compared with uni-SSNHL. Ten patients (62.5%) in the bi-SSNHL group showed hearing recovery in 1 or both ears compared with 56.5 percent of patients with uni-SSNHL. Only 12 (37.5%) of all 32 ears recovered in bi-SSNHL, which was significantly lower than in uni-SSNHL. CONCLUSION: Bi-SSNHL has a very low incidence and lower recovery rate than uni-SSNHL. Recognition of similarities and differences between bilateral and unilateral SSNHL can help in counseling and managing the patients.
