<p><b>OBJECTIVE</b>To evaluate the correlation of single nucleotide polymorphisms (SNP) of Gemin 3(rs197412) in the miRNA biosynthesis with NHL cancer risk and overall prognosis.</p><p><b>METHODS</b>miR-SNP were genotyped using PCR-ligase detection reaction(LAR, LCR) in NHL group of 230 non-Hodgkin lymphoma (NHL) patients and in control group of 120 healthy persons. The survival curves were drawn using the Kaplan-Meier method, and comparisons between the curves were made using the log-rank test. Multivariate survival analysis was performed by using a Cox proportional hazards model.</p><p><b>RESULTS</b>The rs197412 genotype distribution difference was not statistically significant, in NHL and control group; the survival time of patients carrying the rs197412 TT genotype was significantly longer than that of the patients carrying the CC+CT genotype (P=0.007). In addition, rs197412 was independent from the survival of NHL patients by multivariate analysis (RR: 2.138,95% CI: 1.303-3.508, P<0.01).</p><p><b>CONCLUSION</b>The single nucleotide polymorphisms of Gemin 3 (rs197412) in the miRNA processing are not related with NHL risk, but that may affect NHL survival.</p>

To study the effect of hemoporphyrin derivative(HPD) combined with laser irradiation on human breast tumor cell line MCF-7 and normal human umbilical cord blood-derived hematopoietic cells by using MTT assay. The results showed that HPD plus laser irradiation was more efficient for killing MCF-7 cells than normal human umbilical cord blood-derived hematopoietic cells. The photochemical effect with laser irradiation were higher than with light irradiation and it's effect on MCF-7 cells was higher gradually with the increase of HPD concentration.
