ObjectiveTo assess the clinical features of noncompaction of ventricular myocardium (NVM) in children. Methods The clinical data from ifve children with NVM were analyzed, including clinical manifestations, ultrasonic cardio-gram(UCG), electrocardiogram, chest X-ray, the process of diagnosis and treatment, and follow up.Results In ifve patients (3 boys and 2 girls) aged 3 months to 12 years, four of them were hospitalized because of pneumonia with heart failure. None of the ifve patients had thromboembolism. Heart enlargement was observed in all ifve patients on chest X-ray. By 2D ultrasonography, 2 patients had cardiac apex involvement, and 3 patients showed involvement of left ventricular wall and interventricular septum. In one patient, congenital partial defect of the endocardial cushion was observed. All patients were followed up for 3 to 36 months. One patient died of heart failure, 3 patients survived, and one patient was lost to follow-up.Conclusions The common clinical manifestation of NVM is the heart failure. UCG is preferred for NVM diagnosis. In children with refractory pneumonia and heart failure, NVM should be suspected.

Objective To investigate the value of tracing thyroglobulin(Tg)in predicting metastasis of post-operative patients with differentiated thyroid carcinoma(DTC)before its first pre-ablation with 131I. Methods 106 cases with DTC, undergoing total thyroidectomy and lymphadenectomy, were assigned to 2 groups as M0 group (without metastasis)and M1 group(with metastasis). Clinical data including pre-ablation stimulated thyroglobulin (sTg)and pre-operative Tg were determined. sTg, pre-operative Tg, Tg variation(△Tg), and Tg variation rate (△Tg/pre-operative Tg)between 2 groups were compared. The ROC curve and the diagnostic critical point(DCP) were analyzed. Results sTg, Pre-operative Tg, Tg variation, and Tg variation rate were significantly higher than those of M0(all P<0.01). The corresponding areas under the ROC curve(AUC)to differentiate the two groups were 0.913,0.702,0.773,and 0.943,respectively. The best diagnostic value points(DCP)were 40.60 ng/ml and-72.5%. The sensitivity and specificity were 70. 21%, 100. 00%, and 89. 36%, 88. 13%, respectively. Conclusion The pre-ablation sTg seems to be a useful diagnostic marker for predicting metastasis before the first 131I ablation. The sTg value can be effectively corrected by the Tg variation rate,and the sensitivity and accuracy of sTg for metastasis in DTC patients can be improved,finally providing evidence for pre-ablative assessment as well as strategies of 131I therapy.

Objective: To investigate the imaging diagnosis, treatment and prognosis of primary hepatic neuroendocrine tumors. Methods: The clinical features, imaging manifestations, histopathological and immunohistochemical findings and interventional therapy of 6 patients identified with pathologically confirmed primary hepatic neuroendocrine tumors were retrospectively analyzed, and the related literatures were reviewed. Results: All 6 patients presented with symptoms of abdominal pain. 4 patients had solitary hepatic mass and 2 patients had multiple hepatic masses. Magnetic resonance imaging showed low signal intensity on T1 weighted imaging, high signal intensity on T2 weighted imaging and clear boundary; the arterial phase of enhancement scan was uneven and enhanced, and portal venous phase or delayed phase showed continuous enhancement, surrounded by ring enhanced capsule. A pathological diagnosis was primary neuroendocrine tumor of the liver. After interventional treatment, 6 patients had some therapeutic effects. Among them, 4 patients underwent multiple interventional therapies, followed by 4 years of follow-up has shown satisfactory results. Conclusion Primary hepatic neuroendocrine tumors are very rare and their imaging manifestations are specific. Eventually, relies on pathological and immunohistochemical diagnosis. Transarterial chemoembolization therapy can bring satisfactory results in the treatment of primary hepatic neuroendocrine tumor.

Objective To investigate the clinical efficacy of CT-guided 125I seeds implantation combined with gemcitabine + cis-platinum (GP) in the treatment of unresectable non-small cell lung cancer (NSCLC).Methods From January 2013 to January 2017,62 patients with unresectable Ⅱ b-Ⅲb NSCLC were randomly divided into 2 groups.In the study group,32 patients (17 males,15 females,age (62.7± 8.9) years) underwent 125I seeds implantation combined with 4 courses of GP chemotherapy,and 30 patients (18 males,12 females,age (61.9±7.0) years) in the control group underwent concurrent radiotherapy combined with 4 courses of GP chemotherapy.The short-term effects at 3 and 6 months after treatment were compared between 2 groups,as well as the survival time.Log-rank test was used to analyze the data.Results The effective rates at 3 and 6 months after treatment in the study group and control group were statistically significant (90.62％ (29/32) vs 70.00％ (21/30),96.88％ (31/32) vs 66.67％ (20/30);x2 values:3.00 and 7.22,both P＜0.05).The median survival time of the study group and control group were 17 and 15 months (x2 =2.194,P＞0.05).The 1-year survival rates of 2 groups were 87.50％ (28/32) and 76.67％ (23/30),respectively (x2=1.24,P＞0.05),and the 2-year survival rates were 40.62％ (13/32)and 20.00％(6/30),respectively (x2=4.00,P＜0.05).Conclusions 125I seeds implantation combined with GP chemotherapy is a significant treatment for unresectable NSCLC.The short-term efficacy is better than concurrent radiotherapy combined with GP regimen.

Objective:To analyze the value of maximum standardized uptake value (SUV max) of 18F-fluorodeoxyglucose (FDG) PET/CT in differentiating the malignant solitary pulmonary nodules (SPN) from benign ones. Methods:18F-FDG PET/CT imaging data of 84 patients (39 males, 45 females; age: 34-81(average: 61.1) years) with SPN in the First People′s Hospital of Lianyungang between September 2017 and June 2019 were retrospectively analyzed. The pathological results were taken as the gold standard. Differences of SUV max between benign and malignant SPN were analyzed with Mann-Whitney U test, and the best cut-off value for the diagnosis of benign and malignant SPN was measured by receiver operating characteristic (ROC) curve. The diagnostic efficacy was analyzed based on SUV max. Results:The pathological results confirmed 54 patients with malignant SPN, and 30 patients with benign SPN. SUV max of malignant group was significantly higher than that of benign group (5.48±4.08 vs 1.70(0.73, 3.33); U=443.50, P=0.001). The 84 SPN included 58 solid SPN and 26 subsolid SPN. SUV max of malignant subsolid SPN and benign ones were not significantly different ( U=56.00, P>0.05). The diagnostic value of SUV max in 58 cases of solid nodules were analyzed based on ROC curves, and the optimal cut-off value was 1.85. The corresponding diagnostic sensitivity, specificity, accuracy, negative predictive value and positive predictive value were 97.06%(33/34), 62.50%(15/24), 82.76%(48/58), 15/16, 78.57%(33/42), respectively. Conclusions:18F-FDG uptake of malignant SPN were higher than benign ones. The diagnosis of benign and malignant solid SPNs based on SUV max 1.85 has high sensitivity, negative predictive value and accuracy. SUV max has limited diagnostic value on subsolid SPN.

Objective To study the effect of interlocking intramedullary nail on fixing transverse olecranon fracture. Methods Nine pairs of fresh ulna specimens were collected and the transverse fracture model of olecranon was established. Kirschner wire tension band and interlocking intramedullary nail were used to repair the fracture. Cyclic dynamic tension loads with amplitude of 25 N, mean value of 45 N and frequency of 05 Hz were applied to the triceps tendon under simulated elbow flexion conditions of 30°, 45° and 60°, respectively. The fracture displacements of specimens within 300 cycles were recorded in three groups. ResultsAt 30° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.831±0.333) mm and (3.723±2.390) mm, respectively. At 45° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.167±0.374) mm and (2.455±0.609) mm, respectively. At 60° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.407±0.342) mm and (3.112±1.025) mm, respectively. The fracture displacement of interlocking intramedullary nail was smaller. Conclusions The mechanical properties of interlocking intramedullary nail are better than those of Kirschner wire tension band, and the interlocking intramedullary nail is more stable and firmer for fixing transverse olecranon fracture. Moreover, the interlocking intramedullary nail is installed with the operating tool, thus the operation is more accurate and faster, and the operation efficiency is greatly improved.

Objective: To explore the relationship between insulin resistance and plasma hypersensitive reactive protein (hs-CRP) in patients with chronic schizophrenia. Methods: A total of 247 inpatients with chronic schizophrenia (patient group) and 166 cases of normal individuals(control group) were enrolled.Their general demographic and clinical data were collected, fasting blood glucose, hs-CRP, c-peptide and insulin indexes were tested, and insulin resistance index (HOMA-IR) was calculated.The insulin resistance level of the patients group and the control group was compared by Mann-Whitney U test, and the relationship between insulin-resistance and hs-CRP in patients group was analyzed using Spearman correlation analysis. Results: (1)The levels of C-peptide (2.53(2.06, 3.23)ng/ml vs 2.24(1.89, 2.87)ng/ml), insulin (7.68(4.66, 11.97)μIU/ml vs 7.02(4.31, 9.59)μIU/ml) and HOMA-IR (1.75(1.09, 3.07) vs 1.57(0.97, 2.22)) in the patient group were significantly higher than those in the control group(all P<0.05). (2) The levels of HOMA-IR( 1.91(1.21, 3.74) vs 1.70(1.02, 2.72)) in patients with high hs-CRP(≥3 mg/L) was higher than those in the patients with low hs-CRP(<3 mg/L)(P<0.05). (3)Spearman correlation analysis showed that HOMA-IR was positively correlated with plasma hs-CRP level in the patient group (r=0.139, P<0.05). (4)After logarithmic transformation of related variables, multivariate linear regression analysis showed that HOMA-IR was linearly correlated with hs-CRP level and boy weight index. Conclusion The hs-CRP level in chronic schizophrenia has a positive predictive effect on insulin resistance.Detection of hs-CRP level in schizophrenic patients is helpful to assess metabolic risk of insulin.
