Objective To investigate the predictive value of bone metabolism parameters on cardiac autonomic nervous system function in patients with type 2 diabetes mellitus(T2DM).Methods A total of 328 patients with T2DM hospitalized in the Department of Endocrinology of Gansu Provincial People's Hospital were enrolled in this study from October 2022 to October 2023.According to the serum 25(OH)D level,all the participants were divided into<10 ng/ml group(n=80),10～20 ng/ml group(n=173),and 20～30 ng/ml group(n=75).Biochemical indicators,bone metabolic parameters,left ventricular mass(LVM)and left ventricular mass index(LVMI)were compared.Time domain indicators ofheart rate variability(HRV)in 24 h holter electrocardiogram,including the global standard deviation of normal sinus RR interval(SDNN),sinus RR interval mean standard deviation(SDANN),and normal continuous sinus RR interval difference root mean square(RMSSD).Meanwhile,adjacent RR interval difference>50 ms as a percentage of the total inter-period(PNN50),HRV triangle index,standard deviation of the difference between the length of the entire adjacent NN interperiod(SDSD),and 24 h holter electrocardiogram HRV time-domain relevant indicators were compared among the three groups.The influence of bone metabolism parameters on cardiac autonomic nervous function and their correlation were analyzed,and the optimal cutting point of cardiac autonomic nervous function was predicted by receiver operating characteristic(ROC)curve.Results SBP,heart rate(HR),FPG,PWV,PTH and β-CTX in groups of 10 ng/ml,10～20 ng/ml and 20～30 ng/ml decreased in turn(P<0.05),while HDL-C,ABI,25(OH)D,Ca2+and PNN50 decreased.Correlation analysis between Spearman and Pearson showed that 25(OH)D was positively correlated with SDNN,HRV triangle index,PNN50 and rMSSD(P<0.01).Logistic regression analysis showed that 25(OH)D,Ca2+and HR were the influencing factors of cardiac autonomic nervous dysfunction in patients with T2DM.The ROC curve analysis showed that the areas under the ROC curve of 25(OH)D,Ca2+and HR were 0.791,0.607 and 0.629,respectively,with sensitivity of 73.4%,53.2%and 38.7%,and specificity of 74.0%,93.6%and 81.4%,respectively.Conclusions 25(OH)D is the influencing factor of cardiac autonomic nervous dysfunction in patients with T2DM,and patients with high degree of deficiency are more prone to cardiac autonomic nervous dysfunction.

Objective To investigate the clinical efficacy of the"dynamic and static combination"approach in the treatment of Hepple Ⅰ-Ⅲ type osteochondral lesions of the talus(OLT),utilizing external ankle shaking,pulling,and poking manipulations in conjunction with ankle brace fixation.Methods A total of 82 patients diagnosed with OLT,who sought treatment at four hospitals between June 2022 and December 2023,were included in the study.Both the experimental and control groups received ankle immobilization using braces through-out the treatment period.The control group was administered Voltaren Emulgel topically twice daily(morning and evening),with each treatment course lasting 30 days,for a total of one course.The experimental group received additional therapeutic intervention involving shaking,pulling,and poking manipulations,conducted twice weekly,with the same duration and number of treatment courses as the control group.Follow-up assessments were scheduled at 2 weeks,4 weeks,and 2 months post-treatment.Outcome measures included the pain rating index(PRI),visual analogue scale(VAS)for pain intensity,current pain intensity(PPI),American Orthopaedic Foot & Ankle Society(AOFAS)ankle and hindfoot scores,proprioceptive function,and the size of OLT.Results During the longitudinal assessment conducted at 2-week,4-week,and follow-up intervals,the experimental group exhibited superior clinical outcomes compared to the control group,with statistically significant decreases in PRI,PPI,and AOFAS scores(all P＜0.05).VAS scores showed progressive improvement over time,with significant intergroup differences observed at both the 4-week and follow-up assessments(P＜0.05).Biomechanical analysis performed post-intervention indicated improved kinematic repositioning accuracy in the experimental group,as reflected by significantly reduced active-passive error angles(P＜0.05).Importantly,measurements of OLT area revealed notable therapeutic effects in the experimental group(P＜0.05),whereas no statistically significant changes were observed in the control group throughout the study period(all P＞0.05).Conclusions Under the guidance of the"dynamic and static combination"concept,the integration of shaking,pulling,and poking manipu-lation with conventional Western medicine-based conservative treatment for OLT demonstrates more pronounced advantages in alleviating pain,improving ankle joint function,restoring proprioception,facilitating lesion recovery,and enhancing overall quality of life.
