MS, 1HNMR and elemental analysis were used to determine the structures of the new compounds. RESULTS　These compounds are new ones. CONCLUSION　Six compounds (3,9,11,13,18 and 20) showed effects on some different receptors, such as alpha2, D2 and H1, and is worth further studying.

Wnt signaling pathway is a highly conservative signal pathway controlling cell growth,differentiation,apoptosis and self-renewal.This signal pathway is often abnormally activated in tumor development and progression,which can cooperate or antagonize with other signal pathways to regulate tumor prolifera-tion,migration and invasion.This paper makes a review of the recent research of Wnt signaling pathway progression and its function in tumor growth regulation.

RESULTS　Eleven compounds of 3-［(3′-methyl-4′-(substituted phenyl)-1′,3′-butadienyl］ indole were synthesized. They are new compounds. Compound 8 showed different inhibitory effects on HL-60, HCT-8 and Bel7402 cell lines in vitro, and its inhibitory rate of antiinflammation was 100％ at 10-5 mol*L-1 concentration. CONCLUSION　Compound 8 showed high anticancer and antiinflammatory activities, and is worth further studying.

AIM　A series of 4-styrylcoumarin derivatives had been designed and synthesized in order to find compounds of antitumor activities by screening. METHODS　Title compounds (1-20) were synthesized by Phase-Transfer Wittig reaction or Wittig-Horner reaction, and screened by several antitumor models in vitro. Their structures were determined by 1HNMR, MS and elemental analysis. RESULTS　Twenty compounds (1-20) are new compounds. Compound 18 had effects on KB cell lines in vitro. CONCLUSION It was seen that compound 18 had certain antitumor activities, and it was worth further studying.

Objective To study the expression of APE/Ref-1 in gastric cancer. Methods Detection of APE/Ref-1 protein was performed with gastric cancer tissue microarray (TMA) by IHC in gastric cancer, non-neoplastic mucosa and lymph node with metastasis. Results The positive rates of APE/Ref-1 in cytoblast in non-neoplastic mucosa, tumor tissue, and metastatic lymph nodes were 96.6%, 97.1% and 98.9%, respectively, while the positive rates in cytoplasm were 71.8%, 21.4% and 10.0%, respectively and in both cytoblast and cytoplasm were 71.4%, 21.4% and 10.0%, respectively. Compared to non-neoplastic mucosa, tumor lesion had lower APE/Ref-1 expression in cytoblast and cytoplasm. In 35.9% of patients it was decreased slightly and in 11.2% of them it was decreased markedly in cytoblast (P

Objective To study the clinical features of acute pancreatitis (AP) in elderly patients. Methods The elderly AP patients from January 1993 to October 1999 in our hospital were studied retrospectively. Results There are 83 cases with a male to female ratio of 1 5∶1 and a median age of 72 7 years.AP was diagnosed in 83 cases for 107 times which included 80 times of mild AP and 27 times of severe AP 13 patien with APts were diagnosed for more than one times.Abdominal pain was the primary symptom in 94 4% patients. 6 patients had no pain 53 0%(44/83) and 84 6%(11/13) patients had cholelithiasis and recurrent AP respectively.60 5% and 72 6% patients were diagnosed by type B ultrasonic and CT respectively . Conclusions In elderly AP patients,abdominal pain was the primary symptom, but a part of patients had no typical symptoms.Cholelithiasis including biliary sludge was an inducement especially in recurrent AP patients. Type B ultrasonic and CT examination were important means in diagnosis.

By employing the methods of literature research and specialist consultation,comprehensively and systematically collected case history at home and abroad on Chinese and western medicine in the treatment of AIDS,by distilling the etiopathogenisis and pathogenesis,the character,the clinical stage,TCM four methods of examination,di erentiation of symptoms,the therapeutical principle and method and the e ective prescription,etc,the paper clari ed the character,pathology,etiology and pathogenesis of AIDS by the evaluation and statistic of qualitative and quantitative analysis of evidence based medicine,grasped the present situation of the treatment of AIDS with Chinese and western medicine in the treatment of AIDS,the rule of syndrome di erentiation and the facticity and application of the clinical e cacy.All these are used to the TCM handbook of AIDS diagnosis and treatment.

Objectives To evaluate the relationship between phaeochromocytoma and renal cell carcinoma,and to present 2 cases of coexisting phaeochromocytoma and renal cell carcinoma. Methods 2 cases of coexisting phaeochromocytoma and renal cell carcinoma diagnosed and treated were reviewed and studied. A case of left adrenal phaeochromocytoma was disdiagnosed as metastatic carcinoma from the left kidney.Nephrectomy and adrenalectomy were carried out without preoperative preparation crisis occurred in the operation and was managed in time.The another is a case of coexising right adrenal phaeochromocytoma and right renal cell carcinoma.After adequate preoperative preparation,the operation was carried out safely.The postoperative course of both the patients has been uneventful. Conclusions An adrenal growth on the same side of a renal cases may not be a metestatic carcinoma.The possibility of an coexisting phaeochromocytoma shuld be kept in mind.Surgical management was the only means for cure and preoperative preparation was extremely important.

Objective To investigate early diagnosis,treatment and prev ention of tibia fatigue fracture. Methods From August 1988 to July 1999, 66 case s of tibia fatigue fracture were treated with exposure to the irradiation of Zho u Lin Spectrum Treatment Device, plaster splintage, according to their different clinic characteristics and results of X-gram.Results The 66 cases were followe d up for an average of 6 months. The result was excellent in 50 cases, good in 1 6, with the excellent and good rates of 100%. Conclusions As a result of a chro nic course of accumulative injury, the tibia fatigue fracture develops from quan titative changes to qualitative changes. It is essential for medical workers to have a good knowledge of the classification and features of the condition. It is also important for the army to make scientific and reasonable training plans fo r the soldiers.

To determine the possibility whether DNA vaccines pcDNA3/SjSDISP of Schistosoma japonicum to induce autoimmunity and immune tolerance in the vaccinated mice, the titer of the specific antibodies against SjSDISP and the production of the autoimmune antibodies, such as presence of anti-nuclear and anti-dsDNA antibodies in the vaccinated mice were detected by ELISA assay and the toxicity of the plasmid DNA was studied through the observation of the change in body weight and the pathological examination of the major organs in mice. It was found that the titer of the specific antibody against SjSDISP was 1∶400 as determined by ELISA, but no autoimmune antibody could detected. The difference of the body weight of mice between the experimental and the control groups was not significant. No abnormal results of histopathological examination were obtained in both groups. From these observations, it is clear that there is no evidence to show that DNA vaccine pcDNA3/SjSDISP can induce auto-immunity and immune tolerance in mice.
