Investigation on developing a computerized imitating system of pediatric clinical patients / 中华医学教育探索杂志

The computerized imitating system constructed by the Second Affiliated Hospital of Guangzhou Medical University contains four blocks:administration of student infomation,administration of question bank,on-line tests and administration of score inquiry.It's designed to imitate typical pediatric cases,so that the medical students may put themselves into the practical clinical scenario and solve the challenges step by step in one-direction procedure.Teaching with computerized clinical scenario imitating patients can improve students' test resuhs and activate students' learning enthusiasm significantly.It not only helps to solve the contradiction between increasing number of medical students and clinical typical teaching case shortage but also improves the clinical thinking ability of the medical students.This system can also be used as a test bank for pediatric technical skills examination.

Response of concurrent radiation combined with interventional artery infusion chemotherapy in advanced cervical carcinoma / 肿瘤研究与临床

Objective To investigate the clinical curative effects and side effects of concurrent radiotherapy combined with interventional artery infusion chemotherapy in advanced cervical carcinoma.Methods 48 patients with advanced cervical carcinoma were randomly divided into two groups including concurrent radiotherapy combied with interventional artery.infusion ehemotherapy group (25 patients) and radiotherapy group (23 patients).Each patient in the concurrent radiotherapy combined with interventional artery infusion chemotherapy group was given THP,DDP and 5-Fu,repeatedly every 28 days,total 3-4 cycles.Radiotherapy was given at the same time.Results The effective rates of the concurrent radiotherapy combined with interventional artery infusion chemotherapy group and radiotherapy group were 92.0 ％ (23/25)and 69.6 ％ (16/23),respectively.The overall 3 year survival rates for the patients in concurrent radiotherapy eombined with interventional artery infusion chemotherapy group and radiotherapy group were 80.0 ％ (20/25)and 52.2 ％ (12/23),respectively,and there was statistically significant between the 2 groups (all P ＜ 0.05).No more side effects were found in the concurrent radiotherapy combined interventional artery infusion chemotherapy group (P ＞ 0.05).Conclusion Concurrent radiotherapy combined with interventional artery infusion chemotherapy in advanced cervical carcinoma can increase short term therapeutic effect and improve the survival rate of the patients without more side effects.

Studies on the chemical constituents of Fusarium sp. from seagrass endophytic fungus / 中国海洋药物

Five known compounds have been isolated from the culture of an endophytic fungus Fusarium sp., which was originated in a seagrass Spartina alterniflora. Their structures have elucidated by TLC comparision with standard and spectral methods as ergosterol (Ⅰ), ergosterol peroxide (Ⅱ) cinnamic acid (Ⅲ), para-hydroxyphenylpropionic acid (Ⅳ) and beauvericin (Ⅴ), respectively.
