RESUMEN
Endometriosis is a common, complicated, and highly heterogeneous endocrine disease. Many genetic factors could affect the development of endometriosis. We performed a case-control study to evaluate the association between polymorphisms in CYP19A1 rs2899470, GSTM1, GSTT1, and GSTP1 rs1695 and the development of endometriosis in a Chinese population. Between March 2014 and October 2015, 262 endometriosis patients and 275 control subjects were recruited from the Inner Mongolia Medical University. Genotyping was conducted using polymerase chain reaction-coupled with restriction fragment length polymorphism. Individuals carrying the TT genotype of CYP19A1 rs2899470 expressed a higher risk of endometriosis than those carrying the GG genotype, and the adjusted ORs (95%CI) was 2.33 (1.27-4.33). Moreover, those with the TG + TT genotype were correlated with an elevated risk of endometriosis, compared to those with the GG genotype (OR = 1.48, 95%CI = 1.03-2.13). However, GSTM1, GSTT1, and GSTP1 rs1695 polymorphisms did not affect the pathogenesis of endometriosis. In conclusion, our results suggested that CYP19A1 rs2899470 polymorphism is associated with risk for endometriosis in the Chinese population.

Our goal was to analyze the anatomical parameters of the lumbar spine spinous process for an interspinous stabilization device designed for the Chinese population and to offer an anatomical basis for its clinical application. The posterior lumbar spines (T12-S1) of 52 adult cadavers were used for measuring the following: distance between two adjacent spinous processes (DB), distance across two adjacent spinous processes (DA), thickness of the central spinous processes (TC), thickness of the superior margin of the spinous processes (TS), thickness of the inferior margin of the spinous processes (TI), and height of the spinous processes (H). Variance and correlation analyses were conducted for these data, and the data met the normal distribution and homogeneity of variance. DB decreased gradually from L1-2 to L5-S1. DA increased from T12-L1 to L2-3 and then decreased from L2-3 to L4-5. The largest H in males was noted at L3 (25.45±5.96 mm), whereas for females the largest H was noted at L4 (18.71±4.50 mm). Usually, TS of the adjacent spinous process was lower than TI. Based on the anatomical parameters of the lumbar spinous processes obtained in this study, an “H”-shaped coronal plane (posterior view) was proposed as an interspinous stabilization device for the Chinese population. This study reports morphometric data of the lumbar spinous processes in the Chinese population, which provides an anatomical basis for future clinical applications.
