BACKGROUND: Color Doppler flow imaging can exam the early myocardial disorder in type 2 diabetic patients. What does exercise tolerance test work for the examination of such disorder in combination with color Doppler flow imaging (CDFI) ?OBJECTIVE: To analyze in comparison the early evaluation on reduced diastolic function in left ventricle in patients with type 2 diabetes between the examinations of exercise tolerance test combined with color Doppler flow image and simple color Doppler flow imaging.DESIGN: Cases-controlled comparison and self-comparison.SETTING: Department of electrodiagnosis and department of Endocrinology in a municipal hospital.PARTICIPANTS: Thirty-six cases of inpatients with type 2 diabetes were selected from Department of Endocrinology of Shenyang Red Cross Hospital from March to December in 2004, of which, 25 cases were males and 11cases females. The diabetic patients included had no cardiac vascular complications and participated in the study in volunteer. Thirty-two patients who received annual routine health check at the same period were selected as the control, of which, 20 cases were males and 12 cases females.METHODS: Metronics treadmill exercise test equipment was used for exercise tolerance in two groups. Before exercise(at quiescent state) and after exercise tolerance, Vivid 4 CDFI was used to determine flow velocity at E and A peak values respectively, ratio between flow velocities at E peak value and A peak value as well as isovolumtric relaxation time (IRT).MAIN OUTCOME MEASURES: Comparison of cardiac functional indexes before and after exercise tolerance in two groups.RESULTS: Thirty-four diabetic patients accomplished exercise tolerance test, of which, 1 case presented frequent ventricular extrasystole, another one presented precordial pain and stopped the test. In the control, all of 32 cases ratio between flow rates of E peak value and A peak value was remarkably lower than that in the control (0. 90 ± 0. 25, 1.40 ± 0.30, P < 0.05 ); IRT was remarkably longer than that in the control [ (112. 07 ± 20. 16),imental group, the ratio between flow rates of E peak value and A peak value was remarkably lower than that in the control (0.62 ±0. 12, 1.28 ±0.87, P< 0.01 ); IRT was remarkably longer than that in the control[ (138. 10± 19.21), (97.37±9.61) ms, P <0.01].CONCLUSION: CDFI can supervise and evaluate at early stage the cardiac functional changes in type 2 diabetic patients. Due to the induction of exercise tolerance, the combination of exercise tolerance test and CDFI provides more accurate, objective and valuable conclusions at early stage.

Objective:To analyze the short-term clinical outcomes of total laparoscopic distal gastrectomy (TLDG) and laparoscopic-assisted distal gastrectomy (LADG) combined with Billroth-Ⅱ+Braun anastomosis.Methods:Clinical characteristics of patients undergoing laparoscopic distal gastrectomy combined with Billroth-Ⅱ+Braun anastomosis at Department of Gastrointestinal Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University from Jan 2020 to Oct 2022 were analyzed. Patients were divided into TLDG group ( n=62) and LADG group ( n=62) according to the surgical approach. Results:There were significant differences in the preoperative clinical data section between the two groups, and 124 patients (62 in each group) were enrolled after using propensity score matching to balance significant variables. Compared with the LADG group, the TLDG group showed statistically differences in time to first venting [(2.9±1.3) vs. (2.3±0.8) d, Z=-3.072, P=0.002], time to first fluid diet [(5.9±1.3) vs. (5.4±1.4) d, Z=-2.031, P=0.042] and incision length [(7.1±1.4) vs. (4.8±0.8) cm, Z=-6.331, P=0.000]. Total postoperative complication rate in the TLDG group and the LADG group (29% vs. 37%, χ2=0.911, P=0.340) was not statistically significant. Incidence of postoperative pneumonia was lower in the TLDG group than in the LADG group (3% vs. 13%, χ2=3.916, P=0.048), and incidence of all remaining postoperative complications were not statistically significant. There was no statistically significant difference in the incidence of serious postoperative complications between the TLDG and LADG groups ( P=1.000). Multifactorial analysis revealed that male ( P=0.023) and age ≥65 years ( P=0.001) were independent risk factors for postoperative complications. Conclusion:TLDG is safe and feasible and has better short-term clinical efficacy than LADG.

Objective:To clarity the clinical features of juvenile dermatomyositis (JDM) with positive anti-melanoma differentiation associated gene 5 (MDA5) antibody.Methods:Retrospective study.Clinical data of 11 anti-MDA5 autoantibody-positive JDM patients in the Department of Rheumatology and Immunology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 2016 to January 2019 were retrospectively recruited for analyzing their clinical characteristics, pulmonary imaging and pulmonary function, thus summarizing treatment experiences.Results:A total of 11 children with anti-MDA5 autoantibody-positive JDM were recruited, involving 2 males and 9 females, with the average onset age of 1-13 (5.8±4.2) years.Clinical manifestations included rash in 11 cases (100.0%), arthritis in 5 cases (45.5%), and myasthenia in 4 cases (36.4%). Muscle enzyme elevated in 10 cases (90.9%) and serum ferritin (SF) elevated in 9 patients (81.8%). Ten cases (90.9%) showed interstitial lung disease (ILD), manifesting as ground glass opacity at subpleural area on CT scans, restrictive ventilation and decreased diffusion function on lung function test, while respiratory symptoms were absent.All patients were treated with glucocorticoid combined with immunosuppressor.Case 2 developed into rapid progressive pulmonary interstitial disease (RPILD), and died of respiratory failure 2 months later.The remaining was followed up for 1-2 years, and the ILD was relieved.Conclusions:All recruited children with anti-MDA5 autoantibody-positive JDM presented typical rash, and mild muscle weakness with a greater tendency to arthritis.Chinese pediatric patients are prone to complicate with ILD with no respiratory symptoms, but ground glass opacity at subpleural area on CT, and restrictive ventilation and decreased diffusion function on lung function test can be detected.Elevated SF is associated with the development of ILD.Glucocorticoid combined with immunosuppressive therapy is effective to JDM with ILD, but ineffective for RPILD.The mortality of anti-MDA5 autoantibody-positive JDM is high without an effective treatment.

Objective:To investigate the prevalence, distribution, and prognosis of knee joint bone marrow edema (BME) in children with juvenile idiopathic arthritis (JIA).Methods:From January 2017 to December 2019, 128 JIA children in the Children′s Hospital, Capital Institute of Pediatrics were analyzed retrospectively, and 136 knees were included totally. BME was evaluated and counted from eight regions according to the juvenile arthritis MRI scoring system (JAMRIS). Chi-square test, independent sample t test or Mann-Whitney U test were used to compare the clinical characteristics between BME group (36 cases) and non-BME group (92 cases). The prognosis of BME were observed. Results:BME was found in 37 of 136 knee joints (27.2%). The ages of the children in BME group and non-BME were (8±4) and (6±4) years old, and the disease duration were 9 (3, 22) and 4 (2, 18) months, respectively, both with statistically significant differences (age: t=-2.63, P=0.010; duration: Z=-5.78, P=0.013). In 23 joints (62.2%,23/37), BME occurred at multiple locations simultaneously in the knee. Locations with BME, according to the frequency of involvement from most to least, were the lateral tibial plateau with 17, the lateral weight-bearing femur with 16, the medial tibial plateau and the medial femoral condyle both with 15, the medial weight-bearing femur with 12, the lateral femoral condyle with 8, the lateral patella with 7, and the medial patella with 5. The MRI score of most of medial femoral conclyle was 1(7/15). Of the 15 BME joints with the MRI follow-up data with interval (7±3) months, BME disappeared in 10 joints, improved in 3 joints and progressed in 2 joints within 12 months after the treatments. Conclusions:There is a low incidence of BME in JIA affected knee joint. Older children and the children with long disease duration have a higher risk for BME, and more likely involved the weight-bearing surfaces of the joint. The overall prognosis is satisfactory after the standard treatments.

Objective:To explore the imaging manifestation and the value of imaging follow-up in Takayasu arteritis with pulmonary artery involvement in children.Methods:The data of Takayasu arteritis with pulmonary artery involvement in 7 children in Children Hospital, Capital Institute of Pediatrics from July 2014 to June 2019, were summarized retrospectively, including 1 boy and 6 girls. There were 6 children under 1 year old, the age ranged from 2 to 7 months and the median age was 3 months old. Another child was 12 years old. CT images of all cases in the initial diagnosis and during the follow-up were reconstructed. The diameters and wall thickness of arteries were observed, including ascending aorta, main pulmonary artery, left and right pulmonary artery and each lobe pulmonary artery. The diameter ratio of main pulmonary artery to ascending aorta (MPA/AAO) was calculated. The pulmonary artery pressure, the diameters of left and right coronary artery were measured using echocardiography and compared in the initial diagnosis and during the follow-up.Results:All the 7 cases showed main pulmonary artery, left and right pulmonary artery widened, 6 cases showed lobe pulmonary arteries widened, 2 cases showed main pulmonary artery, left and right pulmonary artery wall thickened, and 6 cases showed lobe pulmonary arteries wall thickened. All the 7 cases showed MPA/AAO>1 in the initial diagnosis, but only 1 case (12-year-old girl) presented pulmonary hypertension from echocardiography. All the 7 cases showed coronary artery dilated in different degrees and ranges in the initial diagnosis, including 3 cases with bilateral coronary artery dilatation and 4 unilaterally. Five children were followed up and showed improvement of pulmonary artery dilatation in 4 cases and progress in 1 case. MPA/AAO decreased in 4 cases and increased in 1 case. The pulmonary hypertension of the 12-year-old patient decreased during the follow-up, and the MPA/AAO also decreased from 1.64 to 1.01. Coronary artery dilatation decreased in 4 of 5 cases during the follow-up.Conclusion:CT imaging can clearly show pulmonary arteries, which plays an important role in the diagnosis and assessment of the treatment effect in Takayasu arteritis with pulmonary artery involvement in children.
