OBJECTIVE To investigate the antitumor effect of cadmium (Ⅱ) complex of pyrazolone derivatives 1-phenyl-3-methyl-4-propionyl-5-pyrazolone salicyloyl hydrazide-cadmium (Ⅱ) (Cd-PMPP-SAL) on the murine melanoma B16 cells in vitro and in vivo and its mechanisms. METHODS B16 cells were incubated with Cd-PMPP-SAL at 1.0, 1.5, 3.0, 5.0 and 10.0 mg·L-1 for 24, 48 or 72 h. The prolifera? tion rate of B16 cel s was evaluated by MTT assay. B16 cel s were incubated with Cd-PMPP-SAL at 6.25, 12.50 and 25.00 mg·L-1 for 24 h, while cell morphology was observed by Hoechst33258 staining. Apop?tosis of B16 cells was detected by Annexin Ⅴ-FITC/PI staining. The activity of caspases in B16 cells was detected by caspase activity assay. C57BL/6J mice were inoculated subcutaneously with B16 cells to establish a tumor-bearing model. Five days later, Cd-PMPP-SAL at 6.25, 12.50 and 25.00 mg·kg-1 was injected into tumors of C57BL/6J mice once a day for 12 d. The body mass was recorded daily. One day after the last administration, all the mice were killed and the tumor was harvested. Tumor volume and mass were measured, and the tumor inhibitory rates were calculated. Pathological changes of the tumor, liver and lung were observed under a microscope. The expressions of vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2) in tumor tissues were detected by immuno?histochemistry. The apoptotic cells in transplanted tumor tissues were detected by TUNEL. RESULTS Cd-PMPP-SAL inhibited the proliferation of B16 cells. The IC50 was 4.946 mg · L-1, and 95% confidence interval was 4.24-5.65 mg · L-1. The apoptosis rates(12.8 ± 1.4)% and (18.4 ± 0.4)% of Cd-PMPP-SAL 12.50 and 25.00 mg · L-1 groups were significantly higher than those of control group (1.7 ± 0.1)% (P<0.01). The activity of caspase 3 and 9 of Cd-PMPP-SAL 25.00 mg · L-1 group was significantly higher than that of control group (P<0.01), but there was no significant difference in caspases 3/7. The relative tumor volumes of Cd-PMPP-SAL 6.25, 12.50 and 25.00 mg · kg-1 treated groups from the 8th day of treatment were significantly decreased compared with the model group (P<0.01). The result of paraffin sections showed that the transplanted tumor tissues in Cd-PMPP-SAL 12.50 and 25.00 mg · kg- 1 groups exhibited different degrees of necrosis, but there was no significant pathological damage to the liver or lung tissues of mice. Compared with model group, expressions of VEGF and FGF2 in Cd-PMPP-SAL 12.50 and 25.00 mg · kg-1 treated groups were significantly inhibited (P<0.05), and apoptotic cell rates were significantly higher (P<0.05). CONCLUSION Cd-PMPP-SAL can inhibit growth of B16 cells in vivo and in vitro, which may be associated with induction of tumor cell apoptosis and inhibition of tumor angiogenesis.

Objective To establish nursing intervention for patients with diabetes mellitus and discuss in-fluence of community nursing on rehabilitation of patients with diabetes mellitus. Methods Patients with con-finned diagnosis of type two diabetes mellitus (61 cases) were selected,individual health records were established and health education was given to them,including diet,exercises,psychological nursing,medication instruction and regular blood glucose monitoring. Patients compliance,control of fasting blood glucose and glycosylated hemoglobin were compared before and after nursing intervention. Results Patients compliance such as regular physical ex-amination,diet control,regular blood glucose monitoring and exercises treatment improved after intervention com-pared with those before community intervention (P<0.05). The control of fasting blood glucose and glycosylated hemoglobin was better after intervention compared with those before community intervention (P<0.01). Con-clusion Community nursing intervention for patients with diabetes mellitus proved to have good effect.

Objective To investigate the effect of telephone follow-ups on medication compliance of elderly patients with coronary heart disease after percutaneous coronary intervention(PCI).Methods One hundred and sixty elderly patients with coronary heart disease undergoing PCI were randomly divided into control group(n=79)and experimental group(n=81).Conventional treatment with medication and telephone follow-ups per six months were administered to patients in control group after discharging from the hospital.Besides the same treatment as in the control group,8 telephone follow-ups were made within 12 months from discharging and additional follow-ups were performed if their medication compliance was poor.The two groups were compared in terms of medication compliance 12 months since discharging,and cardiovascular adverse events,readmission rates and restenosis rates within 1 year. Results The medication compliance in the experimental group was significantly better than that in the control group.The rates of cardiovascular adverse events,readmission and restenosis within 1 year were all significantly lower than those of control group(all P<0.05).Conclusion Telephone follow-ups can improve medication compliance of elderly patients with coronary heart diseases after PCI and thereby enhance the curative effects.

Blood glucose level responses to different diets were examined in 12 healthy man. The test breakfasts consist of different proportion of protein and carbohydrate. Three kinds of test breakfast were fed respectively for each person. Blood glucose were measured before and 1, 2 and 4 hr after breakfast. The results indicated that high-CHO diet maintained higher level of blood glucose than other diets in 1-2 hr after breakfast. However the blood glucose level began dropping from 2 hr and dropped below fasting level at 4 hr after breakfast. The high-protein diet resulted in decreasing of blood glucose level in 1-2 hr after breakfast. The blood glucose level then increased continuously until 4 hr after breakfast.The results in this experiment showed that adjustment of the proportion of carbohydrate and protein in diets could maintain the blood glucose to a higher and stable level.
