Purpose To assess the left ventricular global systolic function changes using three-dimensional speckle tracking imaging (3D-STI) in female patients with subclinical hypothyroidism (SHT) undergoing L-thyroxine treatment. Materials and Methods Thirty-eight female patients with SHT and 40 healthy female volunteers of the same age (control group) were selected, all the SHT patients received L-thyroxine therapy and were followed for 1 year after euthyroid status was achieved; all the participants underwent blood biochemical examinations, complete conventional echocardiographic and 3D-STI examinations, left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVEDs), interventricular septal depth (IVSd), left ventricular posterior wall depth (LVPWd), left atrial diameter (LAD), diastolic mitral flow spectrum of A peak, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF) of the two groups were compared, and the correlation of parameters of three dimensional left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), global area strain (GAS), and thyroid stimulating hormone (TSH) with each parameter was analyzed. Results IVSd and LVPWd in the study group were higher than those of the control group (t=3.30 and 3.64, P<0.05). Compared with the control group, GLS, GCS, GRS and GAS of left ventricular of SHT patients in the study group were significantly lower (t=8.60, 11.95, 9.78 and 5.92, P<0.05) before treatment. GLS, GCS, GRS and GAS of SHT patients improved after L-thyroxine therapy, and the difference was statistically significant (t=6.91, 9.41, 6.46 and 4.31, P<0.05).TSH level was negatively correlated with E/A ratio and E (r= - 0.39 and - 0.42, P<0.05), and also negatively correlated with GLS, GCS, GRS and GAS (r= - 0.38, - 0.56, - 0.33 and - 0.41, P<0.05). Conclusion Left ventricular global systolic function changes of SHT patients before and after L-thyroxine treatment can be evaluated properly using 3D-STI.

Objective To evaluate the clinical application value of multi-slice helical CT volumetric (VH) scanning in lumber spine. Methods One thousand of patients with back and leg pain who underwent CT examinations were selected as subjects. We simulated the traditional protocol of single-slice(SS) discrete scanning for L3/4, L4/5, and LS/S1 intervertebral discs. The VH scanning mode was performed with 120 kV, 210 mAs,pitch of 1.5 and coverage of 97. 5 mm. The simulated SS scanning mode was performed with 120 kV, 240 mAs and coverage of 45.0 mm. The diagnostic outcomes and the radiation doses were compared between the two scanning modes. Two groups doctors observed ten terms, including the osseous spinal stenosis,narrowed intervertebral space and so on in two scanning modes respectively. Then consistency analysis of the data was carried out. Results The VH scanning mode showed far more features than the SS mode. The detection rates of the VH mode in the osseous spinal stenosis, narrowed intervertebral space,herniated nucleus pulposus, narrowed lateral recess, vertebral lesion, hypertrophy of L5 transverse process,abnormal direction of facet, facet degeneration, lumbar spondyloschisis, and paraspinal soft tissue were 11.8% (n =118), 38. 5% (n =385), 9. 3% (n =93), 46. 8% (n =468), 31.4% (n =314), 5.7% (n =57), 25.4% (n = 254), 49. 7% (n = 497), 9.9% (n = 99), and 0. 6% (n = 6) respectively, while the detection rates of the SS mode in ten terms were 5.6% (n = 56), 0, 0. 6% (n = 6), 27. 9% (n = 279),22.4% (n =224), 1.2% (n = 12), 16.7% (n = 167), 37.2% (n =372), 0.5% (n =5), and 0.2%(n = 2) respectively. The difference between the two groups had statistically significance (average P <0.05), except the paraspinal soft tissue abnormal (P > 0.05). The detection rates of the VH mode were higher than the SS mode in the osseous spinal stenosis, narrowed intervertebral space, herniated nucleus pulposus, lumbar spondyloschisis, being 6.2% (n = 62) , 38. 5% (n = 385) , 8.7% (n = 87), and 9.4%(n =94), respectively. In addition, VH mode only partially showed the articular facets, narrowed lateral recess, hypertrophy of L.5 transverse process, and paraspinal soft tissue. We could not acquire the imaging slices paralleling to intervertebral discs in SS mode in 467 patients (46.7%) with lumbosacral angle greater than 35°. The radiation dose of VH mode (164.9 mGy/em) was slightly higher than SS mode (147.0 mGy/cm) Conclusion MSCT VH scanning mode can significantly improve the diagnostic rate of lumbar spine diseases compared with SS mode, and was not restricted by the lumbosacral angle with slightly increasing radiation dosage.

Objective:To analyze the clinical characteristics and risk factors of juvenile dermatomyositis (JDM) with relapses by comparing clinical features, treatment and disease course among JDM patients with and without relapses.Methods:A retrospective analysis of 102 JDM patients from Children's Hospital of Nanjing Medical University between March 2017 and March 2021 was carried out. Patients were divided into two groups based on whether a JDM relapse had occurred or not. Initial clinical features, laboratory tests and treatment were compared between the two groups. T-test or Mann-Whitney U test was used for measurement data, chi-square test or fisher exact probability was used for count data. The features associated with risk of relapses were analyzed by multivariate logistic regression. Results:Among 102 children with JDM, twenty patients (19.6%) relapsed during drug reduction or after drug withdrawal. The mean duration to the first relapse was 3.24 years (range: 9 months to 7 years). Myositis specific antibodies (MSA) were positive for 8 (40.0%) patients with relapses. With 5 cases were anti-nuclear matrix protein 2 positive, 2 cases were anti-transcription interme-diary factor 1 gamma positive, 1 case was anti-signal recognition particle (SRP) positive, the other 12 cases were MSA negative. By binary logistic regression analysis, we found that peripheral calcinosis [ OR(95% CI)=17.54(1.55, 198.64), P=0.021], and interstitial lung disease [ OR(95% CI)=3.83(1.27, 11.59), P=0.017] were independently related to JDM with relapses. Fifty-three patients (51.9%) received methylpre-dnisolone pulse therapy for initial treatment and 13 (65.0%) patients with relapses received methylprednisolone pulse for initial treatment. There was no significant difference between the two groups ( χ2=1.70 , P=0.193). Tumor necrosis factor alpha antagonist combined with methotrexate (MTX) had achieved good results in clinical treatment in children with relapses. Conclusion:The risk of relapses is high in children with JDM. Calcinosis and interstitial lung disease at disease onset can predict a relapsing disease course. Aggressive treatment is urgently demanded for patients with JDM, especially those with relapses.

Objective: The aim of this study was to compare the efficacy and safety of metformin/thiazolidinediones (TZDs) / glucagon-like peptide 1 (GLP-1) analogs (triple therapy) with conventional glucose-lowering therapy(conventional therapy) for patients with type 2 diabetes and metabolic syndrome. Methods: A prospective randomized-controlled 26-week study was carried out. A total of 82 patients with type 2 diabetes and metabolic syndrome were randomized to receive either triple therapy protocal or just conventional therapy, altogether with 41 cases in each group. Results: HbA_1C value was significantly reduced in triple therapy group versus the conventional therapy group [(2.23±1.75)% vs (1.48±1.59)%, P<0.05]. Values of body mass index, waist circumference, and visceral fat area were significantly reduced in triple therapy group as compared to those of conventional therapy group [(2.50±1.81 vs 0.92±1.82)kg/m², (6.75±4.92 vs 1.66±3.25)cm, (24.10±19.10 vs 10.02±20.10)cm², all P<0.01, respectively]. Control rates of HbA_1C and fasting plasma glucose for triple therapy were higher than those for conventional therapy (both P<0.05). No hypoglycemia occurred in triple therapy group. Subjects receiving triple therapy experienced more frequent gastrointestinal side effects than those in conventional therapy group (18.87% vs 3.92%, P<0.05). The most common side event was mild nausea (90%). Conclusion Combination therapy with metformin/TZDs/GLP-1 analogs had statistically significant advantages in the control of body weight, waist circumference, and visceral fat area in addition to the control of blood glucose over conventional glucose-lowering therapy in our patient cohort, it seems to be an optimized therapeutic regimen for patients with type 2 diabete and metabolic syndrome.
