Objective To investigate the effect of bone metabolic markers on sarcopenia in elderly patients with type 2 diabetes mellitus (T2DM). Methods A total of 412 patients with T2DM in the department of endocrinology of Nanjing Central Hospital from May 2020 to June 2025 were selected as the research subjects. According to Asian Working Group for Sarcopenia (AWGS) in 2019, these patients were evaluated for skeletal muscle mass index (ASMI), muscle strength, and muscle function, and were divided into a sarcopenia group (84 cases) and a non-sarcopenia group (328 cases). The glucolipid metabolic indexes were detected in both groups of patients, and the bone metabolic markers were evaluated, including procollagen type 1 N-terminal peptide (P1NP), beta-C-terminal telopeptide of type 1 collagen (β-CTX), and 25-hydroxy vitamin D [25-(OH)D]. The factors influencing the occurrence of sarcopenia in T2DM patients were analyzed by logistic regression analysis, and the diagnostic values of bone metabolic markers on sarcopenia in patients with T2DM were assessed by ROC curve. Results The levels of P1NP and 25-(OH)D were lower, while β-CTX level was higher in the sarcopenia group compared to the non-sarcopenia group, with statistical differences (P<0.05). After logistic correlation analysis, it was found that P1NP, β-CTX and 25-(OH)D were all influencing factors for the occurrence of sarcopenia in T2DM patients. ROC curve analysis suggested that combined detection of PINP, β-CTX, and 25-(OH)D had higher diagnostic value, with an area under the curve up to 0.805. Conclusion The abnormal expression of bone metabolic markers is associated with the increased risk of sarcopenia in patients with T2DM. The detection of serum bone metabolic markers expression level is of certain significance for the assessment of diabetes-related sarcopenia.

Objective To evaluate the current situation of disease control in middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) and analyze the relationship with disease cognition. Methods Among the 360 middle-aged and elderly COPD patients diagnosed and treated in our hospital from January 2022 to June 2024 were retrospectively selected as research subjects, and the COPD Assessment Test Questionnaire (CAT), COPD Patient Knowledge Questionnaire (BCKQ) and the hampion Health Belief Model Scale were used to evaluate disease control, disease cognition and health beliefs in COPD patients. The Pearson chi-square test was used to analyze the relationship between disease control level and disease cognition and health beliefs in older patients with COPD. Results A total of 360 middle-aged and elderly COPD patients, 112 were in the complete control group, 189 were in the partial control group, and 59 were in the uncontrolled group, the disease control rate was 83.61%. The differences in disease cognitive scores, severity cognition, susceptibility cognition, disorder cognition, benefit cognition, health motivation, self-efficacy score and total health belief scores in middle-aged and elderly COPD patients with different disease control conditions are statistically significant. The scores of the complete control group were higher than those of partial control group and uncontrolled group, and the scores of partial control group were higher than those of the uncontrolled group (P <0.05). The disease control level of middle-aged and elderly patients with COPD is positively correlated with disease cognitive level and health belief in all dimensions. The higher the disease control level, the higher the disease cognitive level and health belief in the patient . Conclusions Middle-aged and elderly COPD patients still have insufficient awareness of the disease, and the level of disease control needs to be improved. There is a significant correlation between disease cognition, health beliefs and the level of disease control, and the improved cognitive level may help to improve the disease management and control effect. For middle-aged and elderly COPD patients, the community can provide health education courses, personalized health guidance and self-management training to enhance their awareness of diseases, so as to improve the long-term management of COPD and the quality of life of patients.

ObjectiveTo investigate the effects of Shegan Mahuangtang and its pungent and bitter Chinese herbs on the expression of transient receptor potential vanilloid-1 （TRPV1） and bitter taste receptor 14 （TAS2R14） in the lung tissue of the rat model of cold asthma. MethodSeventy SD rats were randomized into 7 groups： normal， model， Shegan Mahuangtang， pungent Chinese herbs， bitter Chinese herbs （6.43 g·kg^-1）， dexamethasone （0.5 g·kg^-1）， and Guilong Kechuanning （10 g·kg^-1）. The rat model of cold asthma was established by intraperitoneal injection and subcutaneous injection of 10% ovalbumin （OVA） and aluminium hydroxide in the limbs， combined with 2% OVA atomization and cold （2-4 ℃） stimulation. The rats were treated with corresponding drugs by gavage and atomization， and the normal and model groups were treated with the same amount of normal saline for 3 weeks. After the last excitation， airway inflammation and cell proliferation were observed by hematoxylin-eosin （HE）， periodic acid-Schiff （PAS）， and Masson staining of the lung tissue. The levels of interleukin-5 （IL-5）， tumor necrosis factor-α （TNF-α）， thymic stromal lymphopoietin （TSLP）， and transforming growth factor-β₁ （TGF-β₁） in the serum were measured by enzyme-linked immunosorbent assay （ELISA）. The expression of TRPV1 and TAS2R14 was detected by immunofluorescence. The expression of TRPV1， TAS2R14， phospholipase Cβ₂ （PLCβ₂）， B-cell lymphoma-2 （Bcl-2）， and α-smooth muscle actin （α-SMA） in the lung tissue was determined by Western blot. ResultCompared with the normal group， the model group showed decreased water intake， food intake， and body weight， increased airway inflammatory cell infiltration， goblet cell proliferation， tissue fibrosis and collagen deposition， elevated levels of IL-5， TNF-α， TSLP， and TGF-β₁ in the serum （P<0.01）， upregulated expression of TRPV1， PLCβ₂， and α-SMA， and downregulated expression of TAS2R14 and Bcl-2 （P<0.05， P<0.01）. Compared with model group， Shecgan Mahuangtang， pungent Chinese herbs， and bitter Chinese herbs increased the water intake， food intake， and body weight， reduced the inflammatory cell infiltration and goblet cell proliferation， alleviated tissue fibrosis and collagen deposition， lowered the levels of IL-5， TNF-α， TSLP， and TGF-β₁ in the serum （P<0.01）， downregulated the expression of TRPV1， PLCβ₂， and α-SMA， and upregulated the expression of TAS2R14 and Bcl-2 （P<0.05， P<0.01）. ConclusionShegan Mahuangtang and its pungent and bitter Chinese herbs can reduce OVA-induced airway inflammation， downregulate the expression of TRPV1， PLCβ₂， and α-SMA， and upregulate the expression of TAS2R14 and Bcl-2 in asthmatic rats. Moreover， bitter Chinese herbs outperformed pungent Chinese herbs， and the combination of them enhanced the therapeutic effect. It is suggested that Shegan Mahuangtang and its pungent and bitter Chinese herbs may ameliorate the OVA-induced airway inflammation by inhibiting TRPV1 and activating TAS2R14.
