Objective To study the changes of gene expression profiling in HL-60 cells treated by Chan'su, and the possible mechanisms of Chan'su-induced apoptosis in HL-60 cells. Methods Apoptosis was determined by morphology and agarose gel electrophoresis of DNA fragmentation. The changes of gene expression profiling were detected with DNA microarray. Results 1%(v/v) Chan'su could obviously induce HL-60 cells apoptosis. In the tested 1152 genes, mRNA expression levels of 9 genes changed prior to apoptosis in Chan'su-treated HL-60 cells. Of the 9 genes, 8 gene mRNA levels were up-regulated and 1 gene mRNA level was down-regulated. Conclusion Apoptosis in HL-60 cells treated by Chan'su was involved in many genes. Bcl-2 down-regulation and IL-8 up-regulation were closely correlated with the Chan'su-induced HL-60 cells apoptosis.

Objective: To analyze the prognostic factors of non-Hodgkin's lymphoma(NHL)and to investigate the prognostic value of peripheral blood absolute lymphocyte count(ALC)at admission for patients with NHL. Methods: Clinical features and follow-up data of 108 patients with pathologically confirmed NHL seen in our hospital between January 2000 and January 2008 were reviewed.SPSS14.0 package was used for statistical analysis.Kaplan-Meier was applied to assess the survival probability.All parameters statistically significant concluded by univariate analysis were then computed as co-variates for multivariate analysis with Cox regression model. Results: The ratio of males to females was approximately 1.5:1.The median age of patients was 48 years.Before treatment.the Ann Arbor clinical classification showed that 61.1% of the cases were of stage Ⅰ and Ⅱ.Approximately 93%of the patients had ECOG performance status(PS)score of 0-1 and 19.2%of the cases had elevated serum lactate dehydrogenase(LDH).According to intemational prognosis index score.80.6%of the patients were in a low risk group.At admission,35.2%of the cases had ALC≤1×10~9/L.Hemoglobin (Hb)≤110g/L and B symptoms were seen in 29.6%and 26.9%of the patients.The mean Hb was 129.2±17.5g/L in cases with ALC>1×10~9/L(n=70)and 98.1±20.6g/L in cases with ALC≤1×10~9/L(n=38),with a statistically significant difference between the two groups(P<0.05).With a median follow-up duration of 2 years,the median overall survival(OS)time was 2.3 years for all patients.The 2-year and 5-year OS rates were 73.2%and 39.6%,respectively.ALC≤1×10~9/L,Hb≤110g/L,B symptoms and intemational prognostic index(IPI)≥2 were statistically significant unfavorable prognostic factors for NHL revealed by univariate analysis.Multivariate analysis showed that ALC≤1×10~9/L,B symptoms and IPI ≥2 were statistically significant unfavorable prognostic factors for NHL. Conclusion: ALC and B symptoms may be prognostic factors independent of IPI for NHL.Evaluation of the prognosis with IPI,ALC,and B symptoms is of clinical value for individualized therapy of NHL patients.
