Objective:To investigate the association of skeletal muscle function(including muscle strength and physical performance) and insulin resistance as well as type 2 diabetes mellitus(T2DM).Methods:The retrospective study included 942 patients who visited the Department of Geriatrics at Renji Hospital, Shanghai Jiao Tong University School of Medicine, between October 2020 and July 2024. Low skeletal muscle function was defined as either reduced muscle strength or impaired physical performance. Muscle strength was assessed by grip strength, while physical performance was evaluated using the 5-time chair stand test. The associations between muscle function, insulin resistance, and T2DM were analyzed.Results:A significant association was observed between decreased skeletal muscle function and a higher prevalence of T2DM( P=0.001). Further analysis revealed that decreased physical performance was significantly associated with increased T2DM prevalence( P<0.001), whereas reduced muscle strength showed no significant association with T2DM prevalence( P=0.331). Linear regression analysis indicated that both the homeostasis model assessment of insulin resistance(HOMA2-IR) and fasting blood glucose levels increased significantly with longer chair stand times( P<0.05). Restrictive cubic spline(RCS) analysis demonstrated a nonlinear relationship between chair-rising time and HOMA2-IR. Notably, when the cumulative chair-rising time exceed 8.1 s, HOMA2-IR increased significantly with prolonged chair stand time. Logistic regression analysis showed that compared with patients with normal physical performance, those with decreased physical performance had significantly higher odds of T2DM( OR=2.64, P<0.001) and insulin resistance( OR=2.34, P=0.002). Conclusion:Decline in physical performance is significantly positively associated with insulin resistance and the risk of T2DM. Morever, when the cumulative chair stand time exceed 8.1 s, HOMA2-IR increases progressively with further prolongation of chair stand time.

Objective:To investigate the association of skeletal muscle fat index(SMFI) with insulin resistance and type 2 diabetes mellitus.Methods:This retrospective study included 1 100 patients from Department of Geriatric, Renji Hospital, Shanghai Jiao Tong University School of Medicine from October 2020 to October 2023. The SMFI measured by chest computed tomography(CT) is used as an indicator to evaluate the quality of skeletal muscle. Spearman and linear regression analysis were used to evaluate the association between SMFI and homoeostasis model assessment for insulin resistance(HOMA-IR). Multivariate logistic regression analysis and restricted cubic spline(RCS) were used to analyze the association of HOMA-IR with the prevalence of type 2 diabetes mellitus. Finally, interaction and stratified analyses were conducted according to age, sex, body mass index, estimated glomerular filtration rate, uric acid, skeletal muscle index(SMI), smoking, alcohol drinking, hypertension, and dyslipidemia.Results:SMFI showed a significant positive correlation with HOMA-IR( r=0.385, P<0.001). Each 1-unit increase in SMFI led to 0.009, 0.011, 0.004, 0.004, and 0.004 rise in HOMA-IR across adjusted models(all P<0.05). Then subjects were stratified into tertiles( T1, T2, and T3) according to SMFI. Logistic regression analysis revealed that the prevalence of type 2 diabetes mellitus significantly increased in T2( OR=2.37, 95% CI 1.30-4.31, P=0.005) and T3( OR=2.85, 95% CI 1.39-5.86, P=0.004) compared to T1. RCS analysis showed that the prevalence of type 2 diabetes mellitus increased with the increase of SMFI when SMFI<157.195. The results of subgroup analysis showed that female, under 60 years old, body mass index<24 kg/m 2, uric acid<420 μmol/L, low SMI, non-smoking, non-alcoholic drinking, and non-hypertensive individuals with higher SMFI were more likely to develop type 2 diabetes mellitus. Conclusions:Elevated SMFI is positively associated with insulin resistance and type 2 diabetes mellitus risk. Reducing SMFI below 157.195 may significantly lower the risk of type 2 diabetes mellitus.

Objective To investigate the correlation between pathologic features and contrast?enhanced ultrasound in patients with breast ductal papilloma. Methods From January 2014 to January 2016,80 patients with breast intraductal tumor treated in our hospital were selected,including 20 cases of breast ductal carcinoma (ductal carcinoma group) and 60 cases of benign tumor (benign group). Both groups received conventional ultrasound, ultrasonic angiography,and pathological feature analysis. Results Breast surrounding hyperecho,internal micro calcification,border edge burr and posterior echo attenuation were more frequently seen onconventional ultrasound in ductal carcinoma groupthan inbenign group(P<0.05). The average scores of contrast?enhanced ultrasound were significantly higher in ductal carcinoma group than in the control group(P<0.05). In the ductal carcinoma group, there were statistical significant differences betweenpatientswith different lymph node metastasis dukes staging ,and differentiation types (P < 0.05). Spearman rank correlation coefficient analysis showed that breast intraductal carcinoma lymph node metastasis and dukes staging,differentiation types were markedly correlated with pathological features and ultrasound imaging (r=0.341,0.368,and-0.289;P<0.05). Conclusions Conventional ultrasound and contrast?enhanced ultrasound have very good imaging featuresin the diagnosis of breast intraductal cancer ,and there is correlation between pathologic features and contrast?enhanced ultrasound in patients with breast ductal papilloma,which can provide values for early diagnosis of breast ductal carcinoma.

Objective To analyze hematosis of modified homemade Buxue decoction discriminate on patients with hemorrhagic anaemia after unilateral total hip arthroplasty and prognosis.Methods88 patients with hemorrhagic anaemia who underwent unilateral total hip arthroplasty in our hospital from February 2015 to Janurary 2017 were selected, they were randomly divided into the observation group and the control group, 44 cases in each group.The control group received pure western medicine after unilateral total hip arthroplasty, the observation group added modified homemade Buxue decoction discriminate on the basis of the control group.Clinical therapeutic effect on anemia, hematosis indexes including hemoglobin (HB), red blood cell (RBC), erythrocrit (HCT) in the two groups were compared, occurrence of complications during postoperative treatment, hip scores were used to compared prognostic differences in the two groups.ResultsTotal effective rate of the observation group 95.45% was significantly higher than the control group (81.82%) (P<0.05);there was no significant difference in Hb, RBC and HCT level before the treatment in the two groups, Hb (130.23±13.09)g/L, RBC (4.16±0.71)×1012/L and HCT (0.42±0.03) in the observation group after the treatment were significantly higher than the control group (P<0.05);complication rate in the observation group 9.10% was significantly lower than the control group (25.00%) (P<0.05);there was no significant difference in hip joint function scores before the treatment in the two groups, hip joint function score in the observation group after the treatment (79.73±5.42)scores was significantly higher than the control group (P<0.01).ConclusionTreatment effect of modified homemade Buxue decoction discriminate on hemorrhagic anaemia after unilateral total hip arthroplasty is significant, can promote recovery of hematosis, hip joint and motor function effectively.
