Objective To explore the clinical value of tissue synchronization imaging(TSI) in assessment of the characteristics of myocardium asynchrony in patients with ischemic cardiomyopathy(ICM). Methods Thirty-eight patients with ICM were divided into two groups: 26 patients without left bundle branch block(LBBB) in group A, and 12 patients with LBBB in group B. The control group consisted of 26 normal healthy subjects. According to 2D color,the characteristics of myocardium motion in each group were compared by TSI. The time for reaching systolic velocity peak(Ts) and early diastole velicity peak(Te) were measured separately in 12 segments. Standard deviations of Ts(Ts-SD) and Te(Te-SD) as well as difference of Ts(Ts max-min) and Te(Te max-min) of all 12 segments were calculated. The myocardium synchronization were assessed in each group. Results ①91.8% segments in the control group showed normal, with only 8.2% segments were slightly prolonged. TSI of all the ICM patients showed an obvious uneven chroma distribution from green to yellow and then to red. There were far more yellow or red segments than in the control group. ②Ts-SD.Ts max-min of LV 12 segments were significantly prolonged in all ICM groups compared with that in the control group ( P <0. 05). Systolic asynchrony was more obvious in group B than in group A. ③Te-SD,Te max-min of LV 12 segments were significantly prolonged in ICM groups than in the control group ( P < 0. 05). Diastolic asynchrony was more obvious in group B than in group A( P < 0. 05). ④Compared with that in the control group, postsystolic shortening(PSS) was common in patients with ICM. 32. 4% segments of group A were detected PSS.and 56. 0% segments of group B were detected PSS. Conclusions Left ventricular systolic and diastolic mechanical asynchrony is obvious in patients with ICM and PSS is common among them. Systolic and diastolic mechanical asynchrony is more severe in ICM patients with LBBB. TSI is the optimal means to evaluate the characteristics of asynchronous myocardial contraction.

Objective To explore the clinical application value of virtual touch tissue quantification (VTQ) technique in Hashimoto's thyroiditis(HT).Methods Fifty-three patients with HT and 46 health subjects were examed by conventional ultrasonography and VTQ, their shear were velocity (Vs) was measured.A receiver-operating characteristie(ROC) curve was drew according to Vs which can obtain the value of optimal operating point for diagnosing HT.Results The 2D ultrasonic appearance of 53 cases HT were classified into five species, but there was no significant difference in the Vs (F = 0.424, P = 0.790).The area under the ROC curve was 0.976,which showed a high statistical significances(P = 0.000).ROC curve displayed that Vs of 2.53 m/s could be used to diagnose HT,the sensitivity and specificity were 87%and 100% ,respectively.Fifty-three patients with HT were classified into three groups according to thyroid function, 10 patients with hyperthyroidism, 25 patients with hypothyroidism and 18 patients with euthyroidism.The Vs of HT among the three groups were no significant difference(P = 0.884), but their Vs were all obviously higher than that of normal thyroid Vs(P = 0.000).Conclusions VTQ technique can evaluate the hardness of thyroid and has some help for differential diagnosis of HT.

Background:
Obesity classifications vary globally and the impact of older age adiposity on incident diabetes has not been well-studied.
Methods:
We examined a random sample of 2,809 participants aged ≥60 years in China, who were free of diabetes at baseline and were followed up for up to 10 years to document diabetes (n=178). The incidence of diabetes was assessed in relation to different cut-off points of body mass index (BMI) and waist circumference (WC) in multiple adjusted Cox regression models.
Results:
The diabetic risk in the cohort increased linearly with the continuous and quartile variables of BMI and WC. The BMI-World Health Organization (WHO) and BMI-China criteria analysis did not show such a linear relationship, however, the BMI-Asian/Hong Kong criteria did; adjusted hazards ratio (HR) was 0.42 (95% confidence interval [CI], 0.20 to 0.90) in BMI <20 kg/m2, 1.46 (95% CI, 0.99 to 2.14) in 23–≤26 kg/m2, and 1.63 (95% CI, 1.09 to 2.45) in ≥26 kg/m2. The WC-China criteria revealed a slightly better prediction of diabetes (adjusted HRs were 1.79 [95% CI, 1.21 to 2.66] and 1.87 [95% CI, 1.22 to 2.88] in central obese action levels 1 and 2) than the WC-WHO. The combination of the BMI-Asian/Hong Kong with WC-China demonstrated the strongest prediction. There were no gender differences in the impact of adiposity on diabetes.
Conclusion
In older Chinese, BMI-Asian/Hong Kong criteria is a better predictor of diabetes than other BMI criterion. Its combination with WC-China improved the prediction of adiposity to diabetes, which would help manage bodyweight in older age to reduce the risk of diabetes.

Objective:To assess the prognostic potential of post systolic shortening (PSS) on cardiac injury in the breast cancer patients after chemotherapy.Methods:This was a prospective cohort study in breast cancer patients after chemotherapy who were followed up to observe the risk of cardiac injury. A total of 69 female patients with HER-2 negative breast cancer were selected in the Fourth Hospital of Hebei Medical University from February to August 2019. The post-systolic strain index (PSI) of each segment of left ventricular myocardium after chemotherapy was obtained by two-dimensional speckle tracking echocardiography. PSI (%) was defined as follows: [(peak strain in cardiac cycle-peak strain in systole)/peak strain in cardiac cycle]×100%. PSS was regarded as meaningful if PSI >20%. End point was cardiac injury, which could be manifested as cardiotoxicity, cardiogenic death, myocardial infarction, unstable angina pectoris, and severe arrhythmias. Occurence of any above mentioned cardiac injuries was considered as end point event. According to the number of myocardial walls with PSS, the patients were divided into three groups: group A (no walls), group B (1 wall), and group C (≥2 walls). Additionally, the patients were also stratified according to tertiles of PSI: layer A (the first tertile), layer B (the second tertile), and layer C (the third tertile).Results:During a median follow-up of 18 months (Q 1=17 months, Q 3=18 months), 17 patients (24.64%) were diagnosed as having end point events. The risk of end point increased with the increase in the number of myocardial walls with PSS and the increase in PSI stratification.After adjusting for age, hypertension, systolic blood pressure, global longitudinal strain, and E peak of mitral early diastolic inflow velocity/average peak early diastolic mitral annular velocity e′ (E/e′), the association remained significant, (Per 1 increase in number of walls with PSS, hazard ratio, 1.96, P=0.007. Per 1% increase in PSI, hazard ratio, 1.44, P<0.001). In terms of predictive ability, the Harrell′s C index of PSS and of PSI was 0.70 and 0.73, respectively, both P<0.01, which indicated moderate accuracy. Conclusions:The presence of PSS in breast cancer patients after chemotherapy can provide independent prognostic information for the future occurrence of cardiac injury.
