Objective To investigate the correlation between exon 10 polymorphism of follicle stimulating hormone receptor (FSHR) and postmenopausal osteoporosis. Methods From August 2017 to March 2019, 136 postmenopausal women hospitalized in the orthopedic department of our hospital due to osteoporosis were selected as the study objects (osteoporosis group), and 118 postmenopausal non osteoporosis women were selected as the control group at the same time (control group). Genomic DNA was extracted from peripheral blood in females of two groups. The fragment of FSHR gene exon 10 was amplified with PCR and sequenced, and its gene polymorphism was explored. Results There was no significant difference between the two groups in age, menopause age, menopause years, diabetes prevalence, hypertension prevalence, glycosylated hemoglobin (HbA1c), and fasting insulin (fins, P>0.05). The levels of tartrate resistant acid phosphatase-5b (tracp-5b) and serum bone alkaline phosphatase (BALP) in osteoporosis group were significantly higher than those in the control group. Body mass index (BMI), lumbar bone mineral density (BMD), and BMD of the femoral neck were significantly lower than those in the control group, and the differences were statistically significant (P<0.05). There were three genotypes of FSHR in 680 polymorphism of exon 10: type A/A, A/S, and S/S. In the control group, A/A type (62.71%) was the most, followed by A/S type (20.33%), and S/S type (16.96%) was the least. In osteoporosis group, S/S type was the main genotype (59.56%), followed by A/A type (28.68%), and A/S type (11.76%) was the least. There was significant difference between the two groups (P<0.05). S/S genotype and BMI were independent risk factors for osteoporosis. BMD of the lumbar spine L2-4 and BMD of the femoral neck were protective factors for osteoporosis (P<0.05). Conclusion FSHR gene polymorphism has a certain correlation with postmenopausal osteoporosis. S/S genotype appears frequently in postmenopausal osteoporosis patients, which may be related to the occurrence and development of postmenopausal osteoporosis. |
