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.

47例骨髓穿刺干抽的临床和病理分析

分析４７例骨髓穿刺干抽的临床和病理改变，干抽占同期１３１９例骨穿的３．６％。根据骨髓细胞的密度和间质纤维增殖的程度，把干抽的原因分为４类：高细胞伴间质细胞增多者１９例（４２．２％）；间质细胞增多者１４例（３１．１％）；高细胞者８例（１７．８％）及低细胞者４例（８．９％）。主要疾病为：急性淋巴细胞白血病（２５．５％），急性非淋巴细胞白血病（１７．０％），慢性白血病（１４．９％），骨髓转移瘤（１０．６     

Antigen DNA isolated from immune complexes in plasma of patients with systemic lupus erythematosus hybridizes with the Escherichia coli lac Z gene.

Antigen DNA was isolated from immune complexes in plasma of three patients with active systemic lupus erythematosus (SLE) using affinity column. The antigen DNA thus obtained was subjected to hybridization experiments in order to investigate its origin. Unexpectedly, plasmid pUC18 used as a probe was found to hybridize with the antigen DNA, pUC18 was then cleaved into three fragments with the restriction enzyme HaeII. A 445-bp fragment containing lac Z DNA hybridized with the antigen DNA. Finally, the lacZ DNA itself was found to hybridize with the antigen DNA. These data strongly suggest that the antigen DNA obtained from three patients is of bacterial origin.     

Lipofectin介导转移的外源性ADA基因在反复上感儿T淋巴细胞的表达

本文对４１例健康儿童和１７例反复上呼吸道感染患儿外周血淋巴细胞腺苷脱氨酶（ＡＤＡ）活性进行了检测。在此基础上筛选出２例反复上感伴ＡＤＡ活性低下患儿。在体外对这２例患儿的外周血Ｔ淋巴细胞进行培养后，以Ｌｉｐｏｆｅｃｔｉｎ（脂质体）介导的方法对其进行了外源性ＡＤＡ基因的基因转移。结果显示：２例患儿体外培养淋巴细胞ＡＤＡ活性较转基因前升高。同步进行的标志基因ｐＢＬａｃＺ的基因转移的检测结果也直观地证实了Ｌｉｐｏｆｅｃｔｉｎ介导的基因转移是成功的。该研究为ＡＤＡ－ＳＣＩＤ淋巴细胞基因治疗的研究提供了初步的体外实验资料。
