Objective:To investigate the diagnostic value of serum CircRNA_0048211 expression level in postmenopausal osteoporosis (PMOP) and its correlation with bone-specific alkaline phosphatase (BALP), osteopontin (OPN), procollagen type I N-terminal propeptide (PINP) and β-crosslaps (β-CTX). Methods:Data of postmenopausal women who underwent physical examination in our hospital from January 2019 to December 2021 were collected. All subjects were measured bone mineral density (BMD) by dual-energy X-ray absorptiometry and divided into PMOP group, decreased bone mass group and normal bone mass group according to BMD level. The serum CircRNA_0048211, BALP, OPN, PINP and β-CTX levels were compared in each group. Binary logistic regression was used to analyze the risk factors of PMOP, the receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of CircRNA_0048211, BALP, OPN, PINP and β-CTX on PMOP. The correlation between CircRNA_0048211 expression level and BALP, OPN, PINP and β-CTX was analyzed by Pearson correlation analysis. Results:A total of 218 patients were included in this study. Age is 60.52±6.83 years (range, 47-76 years), body mass index is 24.27±2.28 kg/m 2 (range, 22.18-25.73 kg/m 2) and menopausal time is 10.16±4.25 years (range, 2.30-21.80 years). There were 40 cases in PMOP group, 97 cases in osteopenia group and 81 cases in normal bone mass group. The serum CircRNA_ 0048211, BALP, OPN, PINP and β-CTX was significantly different between PMOP group, osteopenia group and normal group ( F=21.15, P<0.001; F=12.52, P<0.001; F=17.86, P<0.001; F=14.32, P<0.001; F=15.52, P<0.001). The serum CircRNA_0048211 level in PMOP group (0.37±0.08) were significantly lower than that of osteopenia group (1.05±0.46) and normal bone mass group (1.73±0.81), the difference was statistically significant ( P<0.05). The levels of BALP (28.42±7.35 μg/L), OPN (17.28±7.30 ng/ml), PINP (58.40±14.37 ng/ml) and β-CTX (1.52±0.28 μg/L) in PMOP group were significantly higher than those in osteopenia group (22.61±5.93 μg/L, 11.95±5.64 ng/ml, 49.16±11.24 ng/ml, 0.81±0.17 μg/L) and normal bone mass group (16.30±4.18 μg/L, 7.62±3.25 ng/ml, 35.48±7.12 ng/ml, 0.37±0.10 μg/L), the difference was statistically significant ( P<0.05). Binary logistic regression analysis showed that decreased CircRNA_0048211 expression level [ OR=3.53, 95% CI (2.73, 10.32)] was a risk factor for the occurrence of PMOP ( P<0.001). ROC curve showed that CircRNA_0048211≤0.76 has a diagnostic significance on PMOP, and its combination of BALP, OPN, PINP and β-CTX has the highest AUC [0.95, 95% CI (0.89, 1.00)] in diagnosing PMOP. Correlation analysis showed that CircRNA_0048211 expression level were negatively correlated with BALP, OPN, PINP and β-CTX ( r=-0.46, P<0.001; r=-0.80, P<0.001; r=-0.81, P<0.001; r=-0.69, P<0.001). Conclusion:The CircRNA_0048211 showed low expression in PMOP, which was negatively correlated with BALP, OPN, PINP and β-CTX. The combination of these five factors has certain clinical value in the diagnosis of PMOP.

Obesity is increasing in an alarming rate worldwide, which causes higher risks of some diseases, such as type 2 diabetes, cardiovascular diseases, and cancer. Current therapeutic approaches, either pancreatic lipase inhibitors or appetite suppressors, are generally of limited effectiveness. Brown adipose tissue (BAT) and beige cells dissipate fatty acids as heat to maintain body temperature, termed non-shivering thermogenesis; the activity and mass of BAT and beige cells are negatively correlated with overweight and obesity. The existence of BAT and beige cells in human adults provides an effective weight reduction therapy, a process likely to be amenable to pharmacological intervention. Herein, we combed through the physiology of thermogenesis and the role of BAT and beige cells in combating with obesity. We summarized the thermogenic regulators identified in the past decades, targeting G protein-coupled receptors, transient receptor potential channels, nuclear receptors and miscellaneous pathways. Advances in clinical trials were also presented. The main purpose of this review is to provide a comprehensive and up-to-date knowledge from the biological importance of thermogenesis in energy homeostasis to the representative thermogenic regulators for treating obesity. Thermogenic regulators might have a large potential for further investigations to be developed as lead compounds in fighting obesity.

@#Chronic obstructive pulmonary (COPD) has significant extra pulmonary effects, which could induce atrophy of peripheral skeletal muscle and respiratory muscles, and significantly influence the respiratory function and quality of life. Muscle nuclear factor (NF)-κB activation plays a key role in the skeletal muscle atrophy. This article discussed the potential mechanisms on how NF-κB signaling pathway increasing protein breakdown and reducing muscle regeneration. On this basis, we explored the role of NF-κB in skeletal muscle at-rophy in patients with COPD during exercise.

BACKGROUND:Tai Chi exercise can relieve the decreasing lung function and increase exercise tolerance in patients with chronic obstructive pulmonary disease, but some studies found that Tai Chi exercise did not achieve the desired improvement effect in patients. OBJECTIVE:To objectively evaluate the rehabilitation effects in lung function and exercise endurance of Tai Chi exercise on old patients with stable chronic obstructive pulmonary disease. METHODS:A computer-based online retrieval of PubMed, EMBASE, Web of Science, The Cochrane Library, CNKI, VIP and WanFang databases between January 1980 and July 2014 were searched. Randomized control ed trials of Tai Chi intervening in old patients with chronic obstructive pulmonary disease were col ected, including Tai Chi exercise intervention group and drug or physical education control group. RESULTS AND CONCLUSION:A total of 6 randomized control ed trials were included, with 406 patients. The results of Meta-analyses showed that, compared with the control group, Tai Chi exercise obviously improved the percentage of forced expiratory volume in one second/forced vital capacity (MD=4.62, 95%CI:0.73-8.51, P=0.02), the percentage of forced expiratory volume in one second to the prediction value (MD=4.95, 95%CI:0.33-9.57, P=0.04) and 6-minutes walking distance (MD=33.81, 95%CI:6.00-61.62, P=0.02) in patients with chronic obstructive pulmonary disease. Forced expiratory volume in one second showed no significant difference between Tai Chi exercise intervention group and control group (MD=0.02, 95%CI:-0.10, 0.14, P=0.76). Tai Chi exercise could improve the lung function and exercise endurance in old patients with stable chronic obstructive pulmonary disease, and has positive rehabilitation effects.

Objective To understand and explore the lived study feeling and experience of nursing undergraduate students during high- fidelity simulation training so as to provide the evidence of reforming teaching methods and performing the teaching practice of nursing educators. Methods Phenomenological study of qualitative research was used. In- depth interviews were conducted among 4 focus groups. 28 nursing undergraduate students were interviewed to understand their lived study feeling. Results 5 themes were emerged using Colaizzi's phenomenologic method, including cooperating explicitly, integrating theory with practice closely, promoting disease observation ability and nursing decision making, enhancing self-confidence. Conclusions High- fidelity simulation training was beneficial to integrate theory with practice, cultivate students' comprehensive ability and increase clinical practical opportunities.

Objective: The purpose of this tudy was to dynamicly observe the weight and the bone mineral density (BMD) of the unsexed rabbits with a few self-made standardized phantoms. Methods:The eighteen healthy adult female rabbits were measured for their weight and BMD in preunsexed and postunsexed 5 months, 10 months with quantitative CT(QCT). Results:There were 61.1% of rabbits whose weight and BMD decreased after 5 months of the postunsexed and 100% of rabbits whose weight and BMD decreased after 10 months of the operation. Conclusion:QCT can be used to dynamicly observe curative effect of drugs in various periods as well,and it is a good method to study osteoporosis.
