Dynamic magnetic resonance (MR) imaging has generated great research interest, because it can provide both spatial and temporal information for clinical diagnosis.However, slow imaging speed or long scanning time is still a challenge for dynamic MR imaging. Most existing methods reconstruct dynamic MR images from incomplete k-space data under the guidance of compressed sensing (CS) or lowrank theory, which suffer from long iterative reconstruction time. Recently, deep learning has shown great potential in accelerating dynamic MR. Our previous work proposed a dynamic MR imaging method with both k-space and spatial prior knowledge integrated via multi-supervised network training. Nevertheless, there was still some smoothing needed in the reconstructed images at high acceleration. In this work, we propose cascaded residual dense networks for dynamic MR imaging with edge-enhanced loss constraint, dubbed cascaded residual dense networks (CRDN).Specifically, the cascaded residual dense networks fully exploit the hierarchical features from all the convolutional layers with both local and global feature fusion.We further use the higher-degree total variation loss function, which has the edge enhancement properties, for training the networks.

Objective To summarize clinicopathologic features of papillary thyroid carcinoma (PTC) coexistent with chronic lymphocytic thyroiditis (CLT) and investigate risk factors for lymph node metastasis.Methods The medical records of 4 264 consecutive papillary thyroid carcinoma patients who received surgical treatment from Oct 2013 to Oct 2015 in Peking Union Medical College Hospital were reviewed.The diagnoses was confirmed by histopathological tests.Univariate analysis was performed to identify specific clinicopathologic features of PTC with CLT.Univariate and multivariate analysis were performed to determine whether each clinicopathologic feature was an independent risk factor for lymph node metastasis.Results In all 4 265 cases,there were 3 059 papillary thyroid microcarcinoma (PTMC) (71.7％),1 010 PTC patients (23.7％) with CLT.909 female patients (90％),624 cases with multifocal lesions (61.8％),422 cases with extra-thyroid extension (41.8％),429 cases with lymph node metastasis (42.5％),and 133 cases with metastatic lymph nodes(LNs) ≥6 (13.2％).The median age was 43 years old and median tumor size was 0.8 cm.Patients with CLT were more females (90.0％ vs.70.2％;P ＜ 0.001),younger median age (43 vs.44 years;P =0.001),and lower incidence of lymph node metastasis (42.5％ vs.50.9％;P ＜0.001).CLT was not associated with tumor size,multifocal lesions,extra-thyroid extension and metastatic LNs≥6 (0.8 cm vs.0.7 cm,61.8％ vs.62.9％,41.8％ vs.42.1％ and 13.2％ vs.14.8％,respectively,all P ＞ 0.05).In multivariate analysis,CLT was an independent protective factor for lymph node metastasis (OR =0.713,95％ CI 0.609-0.835,P ＜0.001).In PTC patients with lymph node metastasis,CLT was not associated with lymph node metastasis number (3 vs.3,P =0.300).Conclusions Chronic lymphocytic thyroiditis was an independent protective factor for papillary thyroid carcinoma patients with lymph node metastasis.But in patients with lymph node metastasis,the metastatic number didn't decrease.

Objective To evaluate the clinical and pathological feature,as well as risk factors of lymph node metastasis (LNM) and high-volume LNM (hvLNM) in papillary thyroid microcarcinoma (PTMC) with di ameter ≤0.5 cm.Methods PTMC patients who received surgical treatments in Peking Union Medical College Hospital from Nov.2013 to Nov.2014 were reviewed.Patients were allocated into the ≤0.5 cm group and (0.5-1)cm group according to tumor diameter.Clinical and pathological features were assessed and compared.Risk factors of LNM and hvLNM were also assessed through univariate and multivariate analysis.Results 1414 patients were enrolled,of which 315 patients (22.3％) were in the ≤0.5 cm group.76 LNM (24.1％) and 9 hvLNM (2.9％) were detected in the ≤0.5 cm group.There was significantly less capsule invasion (14.3％ vs 25.0％,P＜0.05),LNM (24.1％ vs 39.8％,P＜0.05) and hvLNM (2.9％ vs 7.9％,P＜0.05) in ≤0.5 cm group than in (0.5-1)cm group.In univariate analysis,patients aging ＜40 years old were more likely to have LNM than those older than 40(38.0％ vs 20.1％,P＜0.05),while male patients tended to have more LNM than female (32.4％ vs 21.9％,P=0.073).No risk factors were identified for hvLNM.In multivariate analysis,multifocality and younger than 40 years old were the independent risk factors of LNM (OR=2.082 and 2.899,P＜0.05),while male tended to be the independent risk factors of LNM (OR=l.807,P=0.058).No independent risk factors was identified for hvLNM.Conclusions A certain proportion of PTMC patients are with tumor diameter ≤0.5 cm,who have lower risk of LNM and hvLNM.Dynamic observation may be an option,especially in older ≥40 years old),unifocal and female patients.

Objective: To investigate the related factors for lymph node metastasis (LNM), especially for high volume LNM (>5 metastatic lymph nodes) in papillary thyroid carcinoma (PTC). Methods: The medical records of 2 073 consecutive PTC patients who underwent lobectomy, near-total thyroidectomy or total thyroidectomy with ipsilateral or bilateral central lymph node dissection in Department of General Surgery, Peking Union Medical College Hospital from November 2013 to October 2014 were reviewed. Clinical and pathological features were collected. Univariate and multivariate analysis were performed to identify the related factors for LNM/high volume LNM. Results: In all 2 073 patients, LNM and high volume LNM were confirmed in 936 (45.15%) cases and 254 (12.25%) cases respectively. In univariate analysis, large tumor size, young patients (<40 years), male were associated with both LNM and high volume LNM. In multivariate analysis, tumor size >2.0 cm, young patients (<40 years), male were independent related factors of LNM (OR=5.262, 95% CI: 3.468 to 7.986; OR=2.447, 95% CI: 2.000 to 2.995; OR=1.988, 95% CI: 1.593 to 2.480, respectively, all P=0.000) and high volume LNM (OR=6.687, 95% CI: 4.477 to 9.986; OR=2.975, 95% CI: 2.224 to 3.980; OR=2.354, 95% CI: 1.737 to 3.191, respectively, all P=0.000). In 1 414 PTMC patients, a similar result was also demonstrated.Compared with young patients (<40 years), old patients (≥60 years) had lower incidence of LNM (25.47% vs. 52.24%, χ²=62.903, P=0.000) and high volume LNM (1.89% vs. 13.18%, χ²=37.341, P=0.000). Additionally, old patients also had lower risk of both LNM (OR=0.316, 95% CI: 0.194 to 0.517, P=0.000) and high volume LNM (OR=0.142, 95% CI: 0.034 to 0.599, P=0.000). Conclusions The tumor size was the main related factor for both LNM and high volume LNM in PTC. The treatment should be more active in patients with tumor size >2 cm with consideration of higher incidence and risk for LNM and high volume LNM. Young patient was another important related factor for LNM and high volume LNM. In PTMC, old patients had lower incidence and risk for both LNM and high volume LNM. Dynamic observation or less surgical extent could be an option for these patients.

Objective To investigate the therapeutic effect of different methods of dressing on the wound after local debridement of dia-betic foot. Methods A total of 53 patients which underwent local debridement of diabetic foot were divided into control group and treatment group. Patients in control group were dressed on traditional measurement,while patients in the treatment group were dressed on the external medicinal wine for the diabetic foot basic on the traditional treatment. The local transcutaneous oxygen partial pressure,ulcer healing rate,av-erage healing time and the amputation rate were observed. Results The healing rate and percutaneous oxygen partial pressure of the treat-ment group were significantly increased than those in the control group (P<0. 05). The average healing time and amputation rate of the treat-ment group were significantly less than those in the control group (P<0. 05). Conclusion Dressing on external medicinal wine after local debridement of diabetic foot can improve the wound healing in the diabetic foot.

Objective To investigate the clinical characteristics of diffuse alveolar hemorrhage. Methods 12 patients with diffuse alveolar hemorrhage hospitalized in Guangzhou NO.1 Hospital were included in the research, whose clinical characteristics were analyzed. Results 7 cases of the 12 diffuse alveolar hemorrhage cases were male and 5 cases were female. 8 cases were caused by ANCA associated vasculitis , 1 cases by connective tissue disease, 1 cases by poisoning, and 2 cases of unknown etiology (medication could be considered). The clinical manifestations were fever (91.67%), hemoptysis (100%), anemia (100%), and dyspnea (3.33%). Conclusion Diffuse alveolar hemorrhage is a life-threatening clinical syndrome. It can be caused by many causes. It should be considered if there is the presence of hemoptysis, dyspnea, anemia, etc. Timely examination and early intervention can effectively improve the prognosis of the disease.

Objective To construct the ?-gal reporter genes containing the 5′-end flanking of endothelial-overexpressed lipopolysaccharide-associated factor 1 (EOLA1) gene in different sequence lengths and identify the sequence, which regulates the gene expression of EOLA1 by the ?-gal analysis system. Methods The target sequences were amplified by the method of genome walker, and were inserted into the upstream of ?-gal gene located in the ?-gal enhancer vector by the directional clone technique respectively; the regulative sequence was identified by analyzing the ?-gal activities of reconstructed plasmid in ECV304 cells. Results The regions, containing 2 659 bp and 1 951 bp upstreaming from exon 1, significantly stimulated the reporter gene activity as compared with that of the ?-gal control vector in transfected cells. But the region, containing 361 bp upstreaming from exon 1, did not stimulate the reporter gene activity. Conclusion There is an up-regulative element of gene transcription in the region of -361 to -1 951 bp in EOLA1 gene upstream.

Objective To identify the promoter sequence of endothelial-overexpressed lipopolysaccharideassociated factor 1 ( EOLA1) gene and to elucidate the molecular mechanisms controlling EOLA1 expression. Methods A DNA fragment containing 1 723 bp 5' upstream of the EOLA1 gene and the transcription start site was generated by polymerase chain reaction and then cloned into a luciferase reporter gene vector,pGL3-basic. The relative luciferase activities driven by this 5'-upstream fragment and a series of deletion mutants were measured in transiently transfected human ECV304 cells,respectively. At last,the 1 723 bp upstream of the EOLA1 gene was analyzed online with Cluster Buster. Results A fragment 785 bp upstream of the EOLA1 coding region was sufficient to promote transcription. Further deletion analysis of the 785 bp fragment indicated that a 68 bp element from-738 to -676 was important for EOLA1 transcription in ECV304 cells. The 1 723 bp sequence contains binding sites for Sp1 and Myf. Conclusion We map the EOLA1 promoter by deletion analysis and reveal that the proximal region ( -738 to -676 bp) ,which contains binding sites for Sp1 and Myf,is essential for human EOLA1 promoter activity in ECV304 cells.
