ABSTRACT

OBJECTIVE@#To investigate the application value of liquid crystal digital display goniometer in total hip arthroplasty.@*METHODS@#From January 2018 to December 2019, 83 patients underwent primary total hip arthroplasty, including 28 males and 55 females, aged 42 to 81 (70.4±7.9) years. There were 63 cases of femoral neck fracture and 20 cases of avascular necrosis of femoral head. All patients used liquid crystal digital goniometer to control the anteversion of acetabular cup prosthesis during operation, and CT scanning was used to measure the anteversion of acetabular cup after operation. The two methods were compared to understand the accuracy of using liquid crystal digital goniometer.@*RESULTS@#Postoperative CT measurement showed that the acetabular anteversion of all patients was in the safe area advocated by Lewinnek. The anteversion angle of acetabular cup measured by liquid crystal digital goniometer was 14.20(12.80 to 15.40)°, and the anteversion angle of acetabular cup measured by postoperative CT scan was 14.20 (13.40 to 15.50)°. There was no significant difference between the two (@*CONCLUSION@#It is an accurate and reliable method to control the anteversion of acetabular cup with liquid crystal digital display angle instrument, which has a good auxiliary reference value.

ABSTRACT

Objective·To explore the association between neuropeptide Y (NPY) gene polymorphism and schizophrenia in Chinese Han population. Methods·Four single nucleotide polymorphism (SNP) loci (rs16148, rs1859290, rs16147, and rs16478 in NPY gene) were selected and genotyped by TaqMan genotyping assay in a case-control study with 678 schizophrenia cases (case group) and 685 healthy controls (control group). The allele, genotype and haplotype frequencies distribution of the SNPs between the groups were compared with SHEsis online software. Results·The distribution of genotype frequency of locus rs16478 showed a nominal statistically difference between the adult-onset schizophrenia (AOS group) and control group (χ2=6.66, P=0.036, P correction=0.144). Under recessive inherited model, the distribution of CC genotype frequency of locus rs1859290 showed statistically difference between the male schizophrenia cases and control group (P=0.012, OR=0.97, 95%CI 0.94-0.99, P correction=0.048). The distribution of haplotype CCTA (consisted of rs16148, rs1859290, rs16147, and rs16478) frequency showed statistically difference between the male AOS group and control group (8.1% vs 13.2%, OR=0.57, P=0.010, P correction=0.040). Conclusion·The polymorphisms in NPY gene may be associated with schizophrenia in Chinese Han population.
