RESUMO

Purpose: This study aimed to investigate the associations between hemoglobin (HGB) levels and bone mineral density (BMD) and fracture risk in type 2 diabetes mellitus(T2DM) population of different ages. Method: This cross-sectional study included 641 patients with T2DM (57.9% males). BMD of the femoral neck (FN), total hip (TH), and lumbar spine (LS) were measured using dual-energy X-ray absorptiometry. The 10-year probability of fracture was assessed using a fracture risk assessment tool (FRAX). HGB and other biochemical indices were measured in a certified laboratory at our hospital. Statistical analysis was performed using SPSS 26.0 and R language (R version 4.1.0). Generalized additive models (GAMs) were used to identify the associations between HGB and BMD and fracture risk. Results: Patients with osteoporosis have lower HGB levels than the non-osteoporotic population and lower FN BMD in patients with anemia than in the non-anemic population. In patients with T2DM, there was sex- and age-related variability in the correlation between HGB levels and BMDs and fracture risk. In older men, HGB level was an independent determinant of BMD and was positively correlated with FN and TH BMD. In non-older women, HGB level was an independent determinant of BMD and fracture risk, positively associated with BMDs and negatively associated with 10-year probability of fracture risk. GAMs revealed a positive linear association between HGB level and BMDs in non-older female patients but not in older male patients. Conclusion: Our study provides a new perspective on the association of HGB level and BMDs with fracture risk. Relatively high HGB levels are a protective factor for bone quality in patients with T2DM. However, the bone-protective effect of HGB is influenced by age and sex and persists only in older men and non-older women with T2DM.

RESUMO

PURPOSE: Accumulating evidence suggests that serum uric acid (SUA) plays a beneficial role in bone health in the general population through antioxidant mechanisms. However, there is controversy over the association between SUA and bone in patients with type 2 diabetes mellitus (T2DM). We aimed to investigate the association of serum UA with BMDs and future fracture risks and its potential influencing factors in those patients. METHOD: This was a cross-sectional study of 485 patients. BMDs at femoral neck (FN), Troch and the lumbar spine (LS) were measured by DXA. The 10-year probability of fracture risk was assessed using the fracture risk assessment tool (FRAX). SUA level and other biochemical indexes were measured. RESULTS: There were lower SUA concentrations in patients with osteoporosis/osteopenia compared with those in the normal group, which only existed in non-elderly men and elderly women with T2DM. After adjustment for potential confounders, SUA was positively associated with BMD and negatively with 10-year probability of fracture risk only in non-elderly men and elderly women with T2DM. Multiple stepwise regression analysis showed that SUA was an independent determinant of BMD and 10-year probability of fracture risk, which also occurred in the above patients. CONCLUSION: These results implied that relatively high SUA is a protective factor for bone in T2DM patients, but the osteoprotective effect of SUA was mediated by age and gender, and persisted only in non-elderly men and elderly women. Large intervention studies are needed to further confirm the outcomes and provide possible explanations.

RESUMO

In order to explore the structural characteristics of phytoplankton community and the water quality and the water quality of the Fenhe scenic spot in Taiyuan, the species composition and the biomass of phytoplankton as well as their correlation with the environmental factors were monitored. The survey selected 9 sampling sites along the up and lower reaches in Fenhe scenic spot of Taiyuan, from Chaicun Bridge to Xiangyun Bridge. During the wet season (June-Octoher) in 2014, specimens were collected, qualitative and quantitative investigation on the algae and monitoring on physicochemical indexes of the water were studied. Meanwhile, the water quality was analyzed and evaluated combining all the physicochemical indexes and cell density. Correlation analysis and RDA were conducted to analyze the relationship of algal community structure and the environmental factors. The main results showed that the dominant phytoplanktons were Cyanophyta, Chlorophyta and Bacillariophyta. The algal biomass first increased and then reduced during the wet season, and the maximum value of hiomass occurred in July. There were many differences among different sampling points. The cell densities of phytoplankton were much higher in three central areas than the other sampling sites. Physical and chemical factors showed a variation tendency in time and space. Based on the results of RDA hetween phytoplankton cell densities and the physic-chemical parameters, the cell densities and the physic..chemical parameters had different correlations. The total cell density had significant positive correlation with dissolved oxygen, and negative correlation with COD. There were extremely significant positive correlations between diatom cell densities and water temperature, air temperature. But the diatom cell density was obviously negatively correlated with COD. It was distinct that the functions of the environment factors were different in temporal and spatial distrihution. The state index of comprehensive nutrition indicated that the total nitrogen content was beyond the standard in all sampling sites during the whole wet season. The water quality varied from oligotrophic to light eutrophic.
