枸杞地黄汤改善老年小鼠记忆障碍和自由基、免疫系统异常改变

目的：研究枸杞地黄汤对老年小鼠学习记忆、自由基及免疫系统的影响。方法：采用水迷宫行为实验检测枸杞地黄汤对老年小鼠学习记忆的影响，通过测定皮层、海马中MDA和SOD水平检测药物对老年小鼠自由基系统异常改变的影响，通过测定老年小鼠免疫器官指数变化检测药物对老年免疫系统异常改变的影响。结果：5、10、20g／kg的枸杞地黄汤不同程度减小老年小鼠学习记忆障碍，降低皮层、海马中MDA水平，增加SOD活性，提高胸腺、脾指数。结论：枸杞地黄汤能够改善老年小鼠学习记忆障碍．调节不正常自由基系统和免疫系统。

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.     

胸腺免疫抑制组分的抗变态反应作用

整体实验表明，胸腺免疫抑制组分肌内注射１ｗｋ对大鼠被动皮肤过敏反应（８、２０、５０和１２５ｍｇ·ｋｇ－１）兔Ａｒｔｈｕｓ反应（４和１２ｍｇ·ｋｇ－１）均有明显的抑制作用。体外实验表明，该药能抑制致敏豚鼠离体回肠平滑肌的过敏性收缩，ＩＣ５０为４４６．７ｍｇ·Ｌ－１。上述结果表明，胸腺免疫抑制组分有抗Ⅰ和Ⅲ型变态反应的作用。     

脂肪饮食与胆石症关系的调查研究

本文通过荤食组、常食组、素食组与胆石症发病率关系的调查,发现荤食组的发病率14/35(40%)比其它两组8/35(22.85%)、2/35(5.71%)更高。同时发现与病人的高血脂水平呈正相关。荤食组的胆固醇和甘油三酯水平分别为5.4±0.85和1.88±1.02,并且比常食组5.08±1.18,1.76±0.62和素食组4.88±0.41,1.67±0.36更高。结果提示:限制大量的胆固醇和脂肪饮食可降低胆石症的发病率。
