肠道T细胞淋巴瘤临床分析

本文总结报告了3例肠道T细胞淋巴瘤(intestinal T-cell lymphoma，ITCL)的诊治资料，并结合文献复习，发现IT—CL多见于中年男性，以腹痛、血便、发热、体质量下降为主要症状，治疗效果差，预后不良。病理改变以肠道溃疡形成为特点，溃疡形态呈多形性、多灶性、不规则，镜下瘤细胞明显异型、弥漫性浸润，中至大细胞多见。肿瘤细胞呈T细胞表型。ITCL临床少见，缺乏特异性临床表现，极易误诊。故临床医师应重视对ITCL临床病理特征、免疫表型和基因型的研究，注意识别，促其早期诊治。     

Cerebral Cortical Aquaporin-4 Expression in Brain Edema following Cardiac Arrest in Rats

OBJECTIVES: Brain edema occurs following clinical as well as experimental cardiac arrest (CA) and predicts a poor neurologic outcome. The objective of this study was to determine the expression of cerebral cortex aquaporin (AQP)-4, a member of a family of membrane water-channel proteins, in brain edema formation following normothermic or hypothermic CA. METHODS: Twenty-four rats were subjected to time-matched normothermic (N-Sham, 37.5 degrees C +/- 0.5 degrees C, n = 6) or hypothermic (H-Sham, 34 degrees C +/- 0.5 degrees C, n = 6) sham experiments and normothermic (N-CA, n = 6) or hypothermic (H-CA, n = 6) CA induced by asphyxiation for 8 minutes. Hypothermia was induced before CA. The animals were resuscitated with cardiopulmonary resuscitation, ventilation, and epinephrine administration. Brain edema was determined by brain wet-to-dry weight ratio at one hour of resuscitation. AQP4 immunoactivity in the cerebral cortex was determined using immunohistochemical staining and was semiquantified as an intensity of staining with an automated cell imaging system. RESULTS: Mild hypothermia in the sham experiments did not alter cerebral cortex AQP4 immunoactivity (mean +/- SD) (55.0 +/- 3.7 in H-Sham vs. 53.3 +/- 1.7 in N-Sham, p > 0.05). N-CA resulted in a significant increase in AQP4 immunoactivity (61.8 +/- 4.5) compared with N-Sham (p = 0.01) and H-Sham (p = 0.03). H-CA attenuated AQP4 compared with N-CA (53.4 +/- 1.3, p = 0.01). Brain wet-to-dry weight ratios were 4.41 +/- 0.07 in N-Sham, 4.40 +/- 0.08 in H-Sham (p > 0.05 vs. N-Sham), 4.55 +/- 0.04 in N-CA (p = 0.004 vs. N-Sham; p = 0.005 vs. H-Sham), and 4.43 +/- 0.09 in H-CA (p = 0.02 vs. N-CA; p > 0.05 vs. N-Sham and H-Sham). CONCLUSIONS: Cerebral cortical AQP4 expression is up-regulated after normothermic CA, which is attenuated by hypothermia induced before CA.

Thymidine labeling index in breast tumors

The relationship between primary tumor proliferative activity and clinical and pathologic characteristics was analyzed in relation to menopausal status in 32 patients with malignant or benign breast disease. The thymidine labeling index (TLI) showed significantly higher median values in the cancer patients (3.48 per cent) than in the patients with benign diseases (1.02 per cent). TLI was not significantly affected by delayed incubation at room temperature for about 1 hour. In the breast cancer patients, TLI did not significantly correlate to tumor size, the presence of axillary lymph node metastasis or pathologic nuclear grading. The only significant difference was limited to the breast cancer patients without axillary lymph node metastasis in relation to menopausal status; the TLI in the premenopausal patients (5.10 per cent) was significantly higher (p<0.05) than that in the postmenopausal patients (2.28 per cent). These data thus suggest that among premenopausal patients without axillary lymph node metastasis, those with a high TLI could be potential candidates for adjuvant chemotherapy.     

Effects ofTripterygium hypoglaucum (Lévl.) Hutch on male fertility

Tripterygium hypoglaucum (Lévl.) Hutch (TH) is a perennial used in Chinese traditional medicine for the treatment of rheumatoid arthritis and various skin disorders. One study showed that daily oral doses of TH significantly reduced the fertility of male rats without apparent toxicity. The effects of daily oral doses of TH on the fertility of men taking it for the treatment of rheumatoid arthritis were evaluated. Sperm concentration, motility and motility grade all were significantly reduced in the 13 men taking TH compared to 11 untreated controls. TH therapy did not affect testosterone, FSH, LH levels, and its antifertility effects appeared to be reversible.

Resumen Triperygium hypoglaucum (Lévl.) Hutch (TH) es una perenne usada en la medicina tradicional china para el tratamiento de artritis reumatoidea y de varios desórdenes de la piel. Un estudio demostró que orales diarias de TH reducían significativamente la fertilidad en ratas macho, sin toxicidad aparente. Se evaluaron los efectos de dosis diarias orales de TH en la fertilidad de hombres que le tomaban para el tratamiento de la artritis reumatoidea. La concentración de espermatozoides, la motilidad y el grado de motilidad, se encontraron significativamente reducidos en los 13 hombres tomando TH comparados con 11 controles no tratados. La terapia con TH no afectó los niveles de testosterona, FSH y LH y sus efectos antifertilidad parecían ser reversibles.

Resumé LeTriperygium hypoglaucum Hutch (TH) est communément utilisé en médecine traditionnelle chinoise pour le traitement de la polyarthrite chronique évolutive (PCE) et de divers troubles cutanés. Une étude a montré que l'administation quotidienne de doses orales de TH réduisait considérablement la fécondité de rats mâles sans provoquer de toxicité apparente. On a évalué les effets de doses quotidiennes administrées par voie orale sur la fécondité d'hommes atteints de PCE et traités au TH. La concentration, la motilité et le degré de motilité du sperme avaient significativement diminué chez 13 hommes traités au TH par comparaison avec 11 témoins non traités. Le traitement au TH n'a eu aucun effet sur les niveaux de testostérone, FSH et LH et ses effets anti-fécondants semblent être réversibles.

急性白血病非系限性分化抗原的动态研究

为探讨仅表达非系限性分化抗原的急性白血病的细胞起源，采用单克隆抗体免疫酶标和聚合酶链反应技术分析了１２例初诊时仅表达非系限性分化抗原的急性白血病化疗后免疫表型及免疫球蛋白重链（ＩｇＨ）和Ｔ细胞受体（ＴＣＲ）γ基因重排的变化。结果表明：初诊时仅表达ＣＤ３８抗原的５例急性白血病，化疗后３例出现Ｔ细胞相关抗原表达，并伴ＴＣＲγ基因重排；５例初诊时仅表达ＨＬＡ－ＤＲ或ＣＤ９的急性白血病，化疗后４例出现Ｂ细胞相关抗原表达，均伴有ＩｇＨ基因重排；２例无任何抗原表达者，化疗后１例表达Ｂ细胞相关抗原，另１例表达骨髓细胞相关抗原。提示免疫标志的动态研究，有助于初诊时免疫学无法分类急性白血病细胞起源的确定。

大鼠实验性肝硬化时甲状腺激素水平及甲状腺形态学变化的研究

将Wistar大鼠分为三组：肝硬化组，给予四氯化碳等复合因素，给药组，除给CCl4等复合因素外，用赤栀黄合剂灌胃41天；正常组给以一般饮食及饮水。结果，与正常组及给药组相比，硬化组血T3、T4测定值低，甲状腺滤泡中胶质明显减少，滤泡细胞与胶质间空泡增多，滤泡上皮细胞内PAS阳性小滴数日增多。表明在实验性肝硬化期间甲状腺参与了抗疾病的代谢活动，其机理可能是肝硬化时肝细胞合成、转运T3，T4的蛋白质减少。运输中的T3，T4减少，活性甲状腺素不足，从而导致甲状腺代偿性功能活跃。赤栀黄合剂具有保肝，恢复甲状腺素水平的作用。     

腐霉对姜根茎腐烂的作用

本文描述了姜根茎腐烂的三种症状类型:青枯型、黄腐型及黄枯型;分别由青枯细菌、腐霉菌及青桔细菌和腐霉苗引起,鉴定出4种致病腐霉:P(?)(?)P.(?)P.(?)和P.(?).通过接种试验,证明腐霉对姜有较强的致病力;与青枯细菌共同为害,病将更严重,故姜的根茎腐烂不完全是细菌青枯病。
