ABSTRACT
Parkinson's disease is a progressive neurodegenerative disorder often seen in the elderly and seriously affects patients' quality of life.Osteoporosis is also a common systemic metabolic bone disease in the elderly characterized by a predisposition to fractures.Studies have shown that Parkinson's disease is highly correlated with osteoporosis, and patients with Parkinson's disease are at high risk for osteoporosis.Hypoxic environments may aggravate the disease and its complications in patients with Parkinson's disease, and the possible mechanisms may involve inhibition of growth and differentiation of osteoblasts, promotion of the formation of osteoclasts, and thus increased risk of osteoporosis under hypoxic conditions.Recent studies have reported that hypoxia, low air pressure, strong sunlight exposure and diets are associated with Parkinson's disease and osteoporosis at high altitudes.This paper reviews research progress on the relationship between Parkinson's disease and osteoporosis in hypoxic environments.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the hematological and molecular characteristics of hemoglobin Q-Thailand in Guangxi, so as to provide reference data for hemoglobinopathy screening.</p><p><b>METHODS</b>A total of 51088 samples were screened by capillary electrophoresis. Samples suspected with Hb Q-Thailand were processed with blood cell count and DNA sequencing. Gap-PCR and PCR-reverse dot blotting were used for the detection of common mutations of alpha and beta thalassemia.</p><p><b>RESULTS</b>The carrier rate of Hb Q-Thailand in Guangxi was 0.06%. The hematological phenotype index(HGB, MCV, MCH, Hb Q-Thailand, Hb A2, Hb QA2) of 28 Hb Q-Thailand heterozygous samples were (125.60±22.30) g/L, (78.22±4.81) fl, (25.79±2.14) pg, (27.37±2.72)%, (1.89±0.22)%, (0.69±0.16)%, respectively, and of 2 Hb Q-Thailand heterozygous combined with beta-thalassemia samples were (125.00±18.39) g/L, (69.65±5.02) fl, (22.00±0.0) pg, (14.80±0.71)%, (4.45±0.07)%, (0.95±0.71)%, respectively. A statistical difference was found in hematological phenotype index between the two groups except HGB (P<0.05).</p><p><b>CONCLUSION</b>In Guangxi, the detected Hb Q-Thailands were mainly heterozygous. Part of Hb Q-Thailand heterozygotes had normal red blood cell parameters, but can still be detected by hemoglobin electrophoresis. When combined with other types of thalassemia, these heterozygotes may still exhibit reduced MCV and MCH or various degrees of anemia.</p>
