Objective To investigate the association between PARK16 gene polymorphism and Parkinson's disease(PD)susceptibility in Chinese Han population.and to analyze its single-nucleotide polymorphism(SNP)genotypes,frequencies and odds ratios(OR)of different genotypes.Methods The association between two SNP loci in PARK16 gene(Rs947211,Rs823128)and PD susceptibility was investigated by TaqMan quantitative polymerase chain reaction(PCR)in 226 PD patients and 362 healthy controls.Allele and genotype frequencies were calculated by the Chi-square test,and the clinical data were also analyzed.Results Three genotypes of Rs947211(GG,AG and AA)account for 34.1%(77/226),46.0%(104/226),19.9%(45/226)in the PD group,and 23.8%(86/362),53.0%(192/362),23.2%(84/362)in the control group,respectively.There was significant difference between two groups (P<0.05).Setting the GG genotype as the reference,OR values of AG and AA genotype were 0.57(95%CI0.38-0.85,P=0.006)and 0.55(95%CI 0.34-0.85,P=0.015),while the OR value for exposure to the A allele(AA+AG)was 0.56(95%CI0.38-0.82,P=0.003).Genotypes of Iate-onset PD were also significantly different from the controls(OR valne of AG=0.46,95%CI 0.27-0.78,P=0.004:OR value of AA=0.35.95%CI 0.18-0.68,P=0.002).And there was no diffefence in clinical features among the 3 genotypes. The frequency of Rs823128, another locus, in PD group was not significantly different from the control group( AA genotype as the reference, OR value of AG was 1. 12, 95% CI 0. 75-1.68, P = 0.568; OR value of GG was 0.99, 95% CI 0.35-2.76, P = 0.994). Conclusion Polymorphism of PARK 16 locus Rs947211 is associated with PD patients in Chinese Han population.

Surgery is currently the most appropriate treatment for early-stage non-small cell lung cancer (NSCLC). Increasing unilateral or bilateral multiple primary lung cancer being found, segmentectomy has attracted wide attention for its unique advantages in the treatment for such tumors. Ground glass opacity dominant early-stage NSCLC is associated with a good prognosis and can be cured by segmentectomy, however, the treatment of solid-dominant NSCLC remains controversial owing to the invasive nature. With the in-depth study on the lymph node metastasis pathway, radiological characteristics and molecular biology of NSCLC, a large part of solid nodules with certain characteristics can also be cured by segmentectomy. This paper reviews the research status and progress about the indication of segmentectomy.
