Objective To study the effect of various methods determining lung volume and fraction dose on the lung dose-volume parameters for lung cancer patients. Methods Twenty patients with lung cancer were rantdomly enrolled into our study and the plan of three dimensional eonformal radiation therapy(3DCRT)was designed by Varian Eclipse TPS.The lung volumes and the dose-volume parameters were measured under CT value of-300- -980, -400- -980 and -500- -980.Under CT value of -400- -980,total lung volumes were confirmed.The dose-volume parameters of V30,V20,V10 and mean lung dose(MLD)were reevaluated after GTV,CTV and PTV were subtracted from the total lung volumes and when the fraction dose was elevated from 2.0 Gy to 10.0 Gy. Results When the CT value ranged from-300--980 to-500--980,the median reduction of the total lung volumes(-9.10%)was significantly higher than that of V30,V20,V10 and MLD(-3.18%,-1.13%,0.82%and-0.79%,respectively).When the total lung volume was fixed at CT value of-400--980,the alterations of V30,V20,V10 and MLD became more apparent as the increase of the subtracted lung volume,among which the alteration of V30 was most significant while V10 the least.Among five cases with a fixed total dose of 60 Gy and PTV less than 140 cm3,the V30,V20,V10 and MLD were increased to a similar extent(about 40%)when the fraction dose was increased from 2.0 Gy to 10.0 Gy.MLD was increased(36%)when the fraction dose was above 6.0 Gy. Conclusions When CT value ranges from-300- -980 to-500- -980,the total lung volume is influenced most.The alteration of V30,being statistically significant,might have some significance but is not enough to determine the plan of radiotherapy clinically.The alteration of V20、V10 and MLD is not statistically significant.When the overlapped target volume is subtracted from the total lung volumes,the alteration of V30 is the most sign:tifhcant while V10 the least.The fraction dose,being the most consuming factor(>10%)when comparing with the CT valHe and targeted volume,can significantly influence the dose-volume parameter.

Objective To investigate the single nucleotide polymorphisms(SNPs) rs3733591(C>T) of SLC2A9 gene in Chinese Han population, and to explore the association of this gene polymorphisms with gout susceptibility, tophi, serum uric acid levels, other clinical and laboratory data and the levels of SLC2A9 mRNA of peripheral blood mononuclear cells(PBMCs). Methods ① A total of 297 primary gout arthritis patients(GA) and 211 normal controls(NC) were enrolled into this study. The clinical and laboratory data of patients were collected. The genotypes and alleles frequencies were measured by using TaqMan ?SNP Geno-typing Assays and the possible association between gene polymorphism of SLC2A9 and gout was investigated by Chi-square test. The odds ratios(OR) and 95% confidence intervals(95%CI) were calculated. ② The lev-els of SLC2A9 mRNA on PBMCs of 86 gout patients(46 patients in remission) and controls were measured by real-time quantitative polymerase chain reaction (RT-qPCR). The nonparametric test was used to analyze the expression in different groups. Results The frequencies of genotypes and alleles of rs3733591(C>T) in gout patients were different from controls(P<0.05). The frequency of TT genotype was significantly lower than that in controls (P<0.05) and the relative risk of this genotype to develop gout was 0.647 (95%CI: 0.452-0.925). Moreover, the frequency of T allele in cases was much lower than in controls (60.9% vs 69.2%, χ2=7.324, P=0.007, OR=0.695), but the frequency of C allele was much higher(39.1% vs 30.8%, χ2=1.440, P=0.007, OR=1.440). Interestingly, the levels of SLC2A9 mRNA on PBMCs in gout patients who carried TC genotype of rs3733591 was higher than those who carried TT genotype(P<0.05). There was no difference in the expression of SLC2A9 mRNA on PBMCs among different genotype carriers of rs3733591 in controls (P>0.05). However, there was no significant difference in the distribution of genotypes and alleles between 30 tophaceous gout patients and 190 non-tophaceous gout patients(P>0.05). Conclusion Results of present study suggest the rs3733591(C>T) polymorphism of the SLC2A9 gene might be associated with gout development, but not with tophaceous gout. The C allele predisposes to gout, and TT genotype and T allele might protect Chinese Han population from developing gout. The rs3733591(C>T) polymorphism probably affects the susceptibility to gout by influencing the f expression of SLC2A9 mRNA susceptibility.

Objective To explore the anti-tumor effects of Egr-IFNγ gene therapy combined with 125I-UdR radionuclide therapy in mice bearing H22 hepatocarcinoma and its mechanism. Methods The recombinant plasmid pcDNAEgr-IFNγ mixed with liposome was injected into tumor. 48 h later, 370 kBq 125I-UdR was injected into tumor. The tumor growth rates at different times were observed. After 3 d gene-radionuclide therapy, the concentration of IFNγ in cytoplasm of H22 cells and cytotoxic activities of splenic CTL of the mice in different groups were examined. Results The tumor growth rates of pcDNAEgr-IFNγ +125 I-UdR group were obviously lower than those of control group, 125I-UdR group and pcDNAEgr-1 +125I-UdR group 6-15 d after gene-radionuclide therapy. IFNγ protein was found in cytoplasm of H22 cells in PcDNAEgr-1FNγ+125I-UdR group after 3 d gene-radionuclide therapy. Cytotoxic activity of splenic CTL in pcDNAEgr-IFN7 + 125I-UdR group was significantly higher than that in the other groups (P<0.01). Conclusions The anti-tumor effects in vivo of pcDNAEgr-IFNγ gene therapy combined with 125I-UdR radionuclide therapy are better than those of 125I-UdR therapy.

Objective To evaluate the change of left ventricular diastolic function and investigate the relation between left ventricular diastolic function and disease activity in rheumatoid arthritis (RA) without clinical manifestations of heart diseases. Methods Seventy consecutive active RA in-patients without clinical manifestations of heart disease were enrolled, while the control group was recruited from outpatient health physical check-up center and consisted of 60 age- and sex-matched healthy subjects. Cardiac related parame-ters were determined by echocardiography and the correlation between left ventricular diastolic function and the disease activity indexes were evaluated. Chi-square test, t test, Pearson or Spearman′s correlation test and Stepwise backward linear regression analysis were used for statistical analysis. Results RA patients had lower mitral inflow E/A ratio (1.2±0.4, 1.5±0.4, P<0.01), higher E/Em ratio (9.6±3.7, 7.8±2.0, P<0.01), longer isovolumetric relaxation time(IVRT)[(64±16) ms,(58±16) ms, P<0.05] than control group. Whilst, RA patients had higher pulmonary venous inflow A wave velocity-time integral (ArVTI) and A wave duration (DAr)[3.2±0.7,(2.8±0.6) cm; 117±11,(102±9) ms, P<0.05]. Moreover, the E/Em was positively corre-lated with C-reactive protein(CRP)(r=0.581, P<0.01), DAS28(r=0.456, P<0.01). Anti-CCP level was also associated with Em and early diastolic pulmonary venous inflow peak velocity(PVD)(r=-0.359, P<0.05;r=-0.305, P<0.05). In addition, multivariate analysis also revealed that there was linear regression relation-ship between E/Em and CRP, DAS28(t=3.266, P=0.002; t=2.949, P=0.005). Conclusion The study has revealed that left ventricular diastolic function is impaired in RA patients and the left ventricular diastolic function parameters is associated with the disease activity indexes. These results suggest that the decline of left ventricular diastolic function is associated with the inflammation activity in RA patients without clinical manifestations of heart disease.
