Synthesis and pesticidal activity of 1,2,3,4-tetrahydroquinoline derivatives

Some new 4-methyl-1,2,3,4-tetrahydroquinolines containing propyl, phenyl and pyridyl radicals at the C-2 position were synthesized from readily available N-aryl-N-alkenylamines. The latter and the tetrahydroquinolines obtained were tested for bactericidal, fungicidal, and herbicidal activities. Among the tetrahydroquinolines tested, those containing an -, -, or -pyridyl substituent have found to be most potent as fungicides.     

中药复方962对老年大鼠外周血淋巴细胞DNA损伤的影响

目的：观察不同年龄组（4月和24月龄）大鼠和连续灌胃给予中药复方962 3个月的老年大鼠的外周血淋巴细胞DNA的损伤情况。方法：利用快速、灵敏的单细胞电泳技术结合激光扫描共聚焦显微镜来观察大鼠外周血淋巴细胞的DNA损伤,以彗星样细胞出现率（计数一定量细胞中彗星样细胞所占的比例）、占彗星长度（“彗星”电泳方向上的最大长度）和尾距（尾部DNA占总DNA的百分比与头尾部中心间距的乘积）来评价淋巴细胞DNA的损伤程度。结果：发现老年大鼠外周血淋巴细胞中彗尾样细胞出现率显著高于青年大鼠（P＜0．01）,复方962不仅能明显降低老年大鼠的淋巴细胞的彗尾样细胞出现率,而且能明显降低老年大鼠外周血彗星样细胞的总彗星长度和尾蹑（P＜0．01）。结论：实验表明复方962对老年大鼠淋巴细胞DNA的损伤有明显的保护作用。

Efficacy of preoperative intracavitary brachytherapy and surgery in patients with stage ⅠB2 and ⅡA bulky cervical cancer

Objective To analyze the outcomes of preoperative intracavitary brachytherapy plus sur-gery in patients with stage ⅠB2 and ⅡA bulky cervical cancer. Methods From January 2001 to January 2007, 77 patients with stage ⅠB2 and ⅡA bulky cervical cancer were included. The diameter of primary tumor was greater than 4 cm. Preoperative intracavitary brachytherapy with the total dose of 20-30 Gy (0.5 cm below the vaginal mucosa) was delivered by 2-3 fractions, one fraction per week. After an interval of 10-14 days, the efficacies of radiotherapy were evaluated and radical hysterectomy with pelvic lymphade-nectomy was performed. Then the treatment complications, clinicopathological characteristics, survival and recurrence were analyzed. Results The tumor shrinkage was observed in all the patients after intracavitary brachytherapy. The CR, PR and SD were 5% (4/77), 36% (28/77) and 58% (45/77), respectively. Radical hysterectomy was successfully performed in all patients. The complications of the combined therapy were mild and only 5 patients had grade Ⅱ or less hematological or gastrointestinal toxicities. The 5-year o-verall survival rate and pelvic recurrence rate were 83% and 12%, respectively. Conclusions Preoperative intracavitary brachytherapy of 20-30 Gy plus surgery is effective in the treatment of stage ⅠB2 and ⅡA bulky cervical cancer without increasing the treatment complications.
