Phase II study of 10-ethyl-10-deaza-aminopterin (10-EdAM; CGP 30 694) for stage IIIB or IV non-small cell lung cancer

Summary Thirty-one patients with stage IIIB or IV non-small cell lung cancer (NSCLC) were treated with intravenous 10-EdAM on a weekly basis. The starting dose was 80 mg/m², with subsequent doses adjusted depending on evidence of toxicity. There were 20 men and 11 women with a median age of 58 years (range, 33–75). Response was evaluated in 30 patients, 5 with evaluable but not measurable tumors and 25 with measurable indicator lesions. There were no complete remissions; 3 patients achieved partial remission. Nine patients had a minor response, 6 showed no change, and 12 had progressive disease. Median survival for all 31 patients was 43 weeks (range, 12–65+). During the first 3-week period, the 10-EdAM dose was reduced or withheld in 19 patients (because of stomatitis in 12, SGPT elevation in 3, skin rash in 2, and granulocytopenia in 2), escalated in 11 patients, and unchanged in 1 patient. A mean of 34–88 mg/m²of 10-EdAM (median, 50) was given per week during the first 5-week period. Myelotoxicity was infrequent and there was no significant nephrotoxicity. Considering the modest side effects of this treatment and the conservative dose-modification schedule which mandated substantial dose reductions, we conclude that 10-EdAM is a promising antitumor agent for NSCLC.     

蛛网膜下腔注射神经降压素对大鼠血压和心率的影响

本文研究了蛛网膜下腔注射神经降压素（ｎｅｕｒｏｔｅｎｓｉｎ，ＮＴ）对大鼠血压和心率的影响，结果表明：注射ＮＴ后血压立即下降，继而有所回升，但不及正常水平，然后再次降低，持续６０ｍｉｎ；心率无明显改变。Ｈ１受体阻断剂苯海拉明能部分阻断ＮＴ的降血压效应，Ｈ２受体阻断剂甲氰咪胍无翻转作用。注射组胺释放剂Ｃｏｍｐｏｕｎｄ４８／８０使血压下降，待血压恢复正常水平后，再注射ＮＴ，其降压效应减弱。结果提示：蛛网     

A study on plasma norepinephrine and epinephrine levels in TCM liver syndromes.

The levels of plasma norepinephrine (NE) and epinephrine (E) were determined by HPLC in 220 patients with various TCM liver syndromes, and in 96 healthy subjects as controls. The plasma NE and E contents were higher in patients with liver excess syndromes, including Ganqi Yujie (GQYJ [symbol: see text]) syndrome, Ganyang Shangkang (GYSK [symbol: see text]) syndrome, Ganhuo Shangyan (GHSY [symbol: see text]) syndrome, and Ganyang Huafeng (GYHF [symbol: see text]) syndrome; while they were lower in patients with liver deficiency syndromes, including Ganqixu (GQX [symbol: see text]) syndrome, Ganxuexu (GXX [symbol: see text]) syndrome, and Ganyinxu (GYX [symbol: see text]) syndrome. Futhermore, when Ganshen Yinxu (GSYX [symbol: see text]) syndrome was turned into GYSK and then into GYHF, the plasma NE and E contents increased in order of precedence; while when GQYJ was turned into Ganyu Pixu (GYPX [symbol: see text]) syndrome, both NE and E contents decreased. The results suggest that the plasma NE and E contents are reliable objective parameters for the study of pathophysiological basis of the liver excess and liver deficiency syndromes, and the liver-kidney and liver-spleen interrelated syndromes.     

不同膳食特点地区中老年人血红蛋白及其与膳食营养的关系

测定分析不同膳食特点地区975例年龄45～74岁中老年人的血红蛋白及其与膳食营养素的关系。结果牧民及城市居民贫血率低，北京及新疆托里分别为7.6％和4.6％。男性比女性血红蛋白高，血红蛋白随年龄增加而降低。相关分析结果血红蛋白与膳食热能、蛋白质、动物蛋白质与总蛋白质比值呈显著正相关。结果说明血红蛋白可用于中老年人营养状态监测。     

赖型钩体flaB2与VR1012中的CpG基序分析

目的：对问号赖型钩端螺旋体（赖型钩体）DNA疫苗[包括内鞭毛蛋白基因（flaB2)和质粒DNA表达载体（VR1012）]的CpG基序（CpG motifs)进行分析，为DNA疫苗免疫机制的阐明和提高DNA疫苗的效能奠定基础。方法：以flaB2与VR1012构建重组DNA的免疫原，对flaB2及VR1012全核苷酸序列进行计算机分析（分类、计数和定位）。结果：CpG的“C”的侧翼为两个嘌呤，“G”的侧翼为两个嘧啶，在flaB2中共3个，分别为GACGCT，GACGTC和GACGCC；在VR1012中共11个，分别为GACGTC1个，GACGCT2个，GACGCC1个，GACGTT1个，GGCGTT2个，GGCGCT2个，GGCGCC1个，AACGCT1个，其中特别重要的TGACGTCA4个和TAACGCCA有1个，位于5'端456－463；509－516；592－599；778－785和486－493；4个TGACGTCA和1个TAACGCCA均位于5'端且相对集中。结论：赖型钩体flaB2与VR1012构成的DNA疫苗含有TGACGTCA等CpG，这些基序又称免疫刺激序列，构成了DNA疫苗中的佐剂。     

New posture equilibrometer for the diagnosis of vestibular disease

Summary The vestibulospinal level of vestibular function is commonly neglected in the evaluation of vertiginous patients. We have now developed a new posture equilibrometer. A transducer is placed on the head of the subject being tested. With this meter we can record body swaying, X (left-right) and Y (fore-aft) components of angular displacement, angular velocity, and angular acceleration. A detailed analysis of the data can be made by having patients keep their eyes either open or closed during the Romberg test. The head is turned left or right in this test, while the eyes are opened and closed in the Mann test. The posture equilibrometer has enabled us to evaluate more precisely vestibulospinal function and sensory interactions. Offprint request to: N. C. Zhong     

不典型性脑膜瘤52例CT诊断分析

回顾性分析了22例少见部位的脑膜瘤，22例CT表现不典型及8例CT误诊脑膜瘤的CT表现，以确定脑膜瘤不典型表现与CT误诊的关系。结果显示脑膜瘤的CT误诊多数缘于经验不足与疏忽，少数为极不典型表现所致。若检查全面、阅片仔细．术前CT定性率可由90％提高至96．25％。
