AIM: To analyze loss of heterozygosity (LOH) and homozygous deletion on p53 gene (exon2-3, 4 and 11), chromosome 10q22-10q23 and 22q11.2 -22q12.1 in human hepatocellular carcinoma (HCC).METHODS: PCR and PCR-based micr...AIM: To analyze loss of heterozygosity (LOH) and homozygous deletion on p53 gene (exon2-3, 4 and 11), chromosome 10q22-10q23 and 22q11.2 -22q12.1 in human hepatocellular carcinoma (HCC).METHODS: PCR and PCR-based microsatellite polymorphism analysis techniques were used.RESULTS: LOH was observed at D10S579 (10q22-10q23) in 4 of 20 tumors (20%), at D22S421 (22q11.2-22q12.1) in 3 of 20(15%), at TP53.A (p53gene exon 2-3) in 4 of 20 (20%), at TP53.B (p53gene exon 4) in 6 of 20(30%), and at TP53.G (p53gene exon 11)in 0 of 20(0%). Homozygous deletion was detected at 10q22-10q23(8/20; 40%), 22q11.2-22q12.1(8/20; 40%), p53 gene exon 2-3(0/20;0%), p53gene exon 4(6/20; 30%), and p53gene exon 11(2/20; 10%).CONCLUSION: There might be unidentified tumor suppressor genes on chromosome 10q22-10q23 and 22q11.2-22q12.1 that contribute to the pathogenesis and development of HCC.展开更多
目的观察窄谱中波紫外线(NB-UVB)治疗寻常型银屑病的临床疗效并分析Th17细胞及相关细胞因子在治疗前后与银屑病皮损面积和严重程度(psoriasis area and severity index,PASI)评分的相关性。方法选取符合寻常型银屑病诊断标准的患者40例...目的观察窄谱中波紫外线(NB-UVB)治疗寻常型银屑病的临床疗效并分析Th17细胞及相关细胞因子在治疗前后与银屑病皮损面积和严重程度(psoriasis area and severity index,PASI)评分的相关性。方法选取符合寻常型银屑病诊断标准的患者40例作为治疗组,采用NB-UVB照射治疗,以PASI评分评价疗效。另随机选取30名健康者作为对照组。分别检测对照组和患者治疗前、后外周血Th17细胞百分比及血清中IL-17、IL-22及IL-23的水平,并分析其与PASI评分的相关性。结果外周血Th17细胞比较:患者治疗前Th17细胞百分比明显高于健康对照组,差异有统计学意义(P<0.05);光疗12周后,患者外周血Th17细胞百分比与光疗前相比显著下降,差异有统计学意义(P<0.05);此外,NB-UVB治疗前后患者Th17、IL-17、IL-22及IL-23水平与PASI评分均呈正相关(P<0.05)。结论 NB-UVB照射可明显下调外周血Th17细胞及IL-17、IL-22和IL-23的水平,可能是NB-UVB治疗银屑病的机制之一。NB-UVB治疗寻常型银屑病疗效好,安全性高。展开更多
