AIM To compare the effects of probimane( Pro), bimolane ( Bim) and razoxane( Raz) on animal tumor metastasis in vivo . METHODS A biological inoculation method for assessment of pulmonary metastasis of Lewis lung carcinoma(3LL) was employed. RESULTS Pro and Bim inhibited the pulmonary metastasis of 3LL both from d 2 and from d 8 injections, but Raz only inhibited the pulmonary metastasis of 3LL from d 2 injections. Pro inhibited the pulmonary metastasis of 3LL more potently than Bim did at equitoxic dosage. CONCLUSION Pro is better in the treatment of pulmonary metastasis of 3LL than Raz for its possible novel molecular mechanisms.

Objecfive To investigate the role of serum Insulin-like growth factor(IGF)-1,insulinlike growth factor-binding potein(IGFBP)-3 in children with Henoch-Schonlein purpura(HSP).Methods The serum concentration of IGF-1,1GFBP-3 was measured by enzyme-linked immunosorbent assay(ELISA)method in 45 acute SHP patients,40 recoverv patients and 30 healthy controls.Results The serum levels of IGF-1 [(452±183)μg/L],IGFBP-3 [(13 897±3124)μg/L] and C-reactive protein(CRP)[(20±8)mg/L]in acute phase were significantly higher than those in healthy controls(P<0.0 1)and higher than those during recovery period.The serum level of IGF-1,IGFBP-3 for the HSP patients dropped back slowly and their levels during recovery period were the same as those in healthy controls(P>0.05).The serum levels of IGF-1[(621±253)μg/L] and IGFBP-3[(18 763±3173)μg/L] were higher in the renal damage group than in the non-renal damage group(P<0.01).and the same in patients with gastrointestinal symptoms group as in patients without gastrointestinal symptoms group(P>0.05).whereas the serum level of CRP was not significantly different(P>0.05).The serum levels of IGF-1,IGFBP-3 showed positive correlation with the level of CRP(r=0.624,0.672,P<0.01).Conclusion The IGF-1 and IGFBP-3 may play an important role in the pathological mechanism of HSP.The level of IGF-1 may be used as an indicator for HSP disease activity and progression.IGF-1 mav have a close relation with the damageof renaJ system in HSP.

BACKGROUNDWith the development of social industrialization and aging of the population, patients with lung cancer have the tendency of becoming youthful and elderly, therefore the way of treatment should be also changed. In resent years, lung cancer in young and elderly patients have been reported respectively, but simultaneous contrast analysis of clinical feature and prognosis in elderly, normal and youthful patients have been rarely reported. Based on the clinic data in the patients, the clinical feature and prognosis of patients with non-small cell lung cancer at different ages were analyzed.
METHODSFrom January 1996 to January 2003, 1380 patients with NSCLC were treated surgically in thoracic department in our hospital, the patients were divided into three group based on their age, group 1 (G1) (range ≤40), group 2 (G2) (range 41-69), group 3 (G3) (range ≥70). The clinical feature and prognosis were analyzed in each group.
RESULTSThe mean age in the whole group was 58.16±0.26, and 35.76±0.57 (range 12-40) in G1, 58.00±0.22 (range 41-69) in G2, 72.30±0.21 (range 70-80) in G3. The ratio of lung cancer in female between G1 and G3 was significant different (P=0.024). The coexisting diseases in G3 were more common than those of other groups (P=0.000). Squamous cell carcinoma was the main type in histology, accounting for 41.79% (28/67), 54.12% (644/1190) and 58.54% (72/123) in each group respectively (P=0.080), but the ratio of adenocarcinoma, higher than that of other groups, were 43.28% (29/67), 29.50% (351/1190) and 26.82% (33/123) (P=0.036). Lobectomy and pneumonectomy were the main surgical procedures, accounting for 58.21%, 65.29%, 78.86% (P=0.004) and 34.33%, 26.22%, 12.20% (P=0.001), respectively. The ratio of stage III were 43.28% (29/67), 38.82% (462/1190), and 26.02% (32/123) in each groups (P=0.015). 55.22% (37/67) in G1 received adjuvant chemotherapy, 47.48% (565/1190) in G2, and 29.27% (36/123) in G3 (P=0.000). 5-year survival rate was 38.96% in the whole group, 29.99% in G1, 39.61% in G2, and 37.99% in G3 (P=0.494).
CONCLUSIONSIn young patients with non-small cell lung cancer, female and adenocarcinoma make up the majority of the number, and a lot of patients are in advanced stage and likely to adopt adjuvant chemotherapy. While in elderly, squamous cell carcinoma accounts for the majority of the number, and more coexisting diseases are accompanied, much more complications occur after surgical procedure. Nevertheless, their prognosis has no significant difference.
