ABSTRACT
Facial reenactment is aimed at animating a source face image into a new place using a driving facial picture. In a few shot scenarios, the present strategies are designed with one or more identities or identity-sustained suffering protection challenges. These current solutions are either developed with one or more identities in mind, or face identity protection issues in one or more shot situations. Multiple pictures from the same entity have been used in previous research to model facial reenactment. In contrast, this paper presents a novel model of one-shot many-to-many facial reenactments that uses only one facial image of a face. The proposed model produces a face that represents the objective representation of the same source identity. The proposed technique can simulate motion from a single image by decomposing an object into two layers. Using bi-layer with Convolutional Neural Network (CNN), we named our model Bi-Layer Graph Convolutional Layers (BGCLN) which utilized to create the latent vector's optical flow representation. This yields the precise structure and shape of the optical stream. Comprehensive studies suggest that our technique can produce high-quality results and outperform most recent techniques in both qualitative and quantitative data comparisons. Our proposed system can perform facial reenactment at 15 fps, which is approximately real time. Our code is publicly available at https://github.com/usaeed786/BGCLN.

Objective To evaluate the safety and efficacy of transcatheter arterial embolization (TAE) in the management of refractory hematuria of prostatic origin (RHPO). Methods This retrospective study from 6 hospitals in china consisted of 31 patients (mean age 75.0±7.5 years, range 58 to 84 years) who underent transcatheter arterial embolization (TAE) for RHPO between February 2011 and January 2017. Patients with RHPO who had complete imaging and clinical data were enrolled. Patients with incomplete clinical data, inability to assess hemostasis, and contraindications to TAE were excluded. The cause of RHPO was benign prostatic hyperplasia (BPH) in nine patients, prostate cancer in twelve, transurethral resection of prostate in four, open prostatectomy in two and prostatic sarcoma in four. Superselective arterial embolization, non-superselective arterial embolization or intra-arterial infusion chemotherapy was performed according to the etiology and angiography. Angiographic findings, technical success rate, clinical success rate, complications were recorded. Results Of the 31 patients, 6 patients (19.4％) were with active bleeding, 4 (12.9％) with aneurysm and 27 (87.1％) with abnormal neovascularization on the angiogram. The 31 patients underwent a totle of 37 TAE, the technical success rate was 100.0％(37/37) and the recent hemostasis success rate was 90.3％(28/31). The incidence of mild complications was 38.7％(13/31), there was no serious complication associated with TAE. Conclusion TAE is a safe and effective method for the treatment of refractory hematuria of prostatic origin.
ABSTRACT
Objective@#To investigate relationship between the clinicopathological features and prognosis of T1 esophageal carcinoma.@*Methods@#Data from 212 T1 primary esophageal cancer patients, who underwent radical surgery in The Fourth Hospital of Hebei Medical University from Jan 2001 to Dec 2009 were enrolled. There were 148 males and 64 females. There were 91 patients with stage pT1a and 121 patients with stage pT1b.@*Results@#The survival of the 212 patients was 27~108 months, and the median survival was 80.8 months. The 1, 3, and 5 year survival rates of patients with stage T1a were 100%, 97.8% and 94.5%, respectively, and the median survival was 86.8 months. The 1, 3, and 5 year survival rates of patients with stage T1b were 100%, 95.9% and 74.4%, respectively, and the median survival was 76.2 months. The rate of lymph node metastasis in 121 patients with stage T1b was 26.4% (32/121). The lymph node metastasis rates in patients with stage sm1, sm2 and sm3 were 11.6% (3/26), 15.0% (6/40) and 41.8% (23/55), respectively. There was no significant difference in lymph node metastasis between stage sm1 patients and stage sm2 patients (P=0.973). Lymph node metastasis rates in patients with stage sm3 were higher than those in stage sm1 and sm2 (P<0.05).@*Conclusion@#Radical resection of esophageal carcinoma with peripheral lymph node dissection is recommended for patients with T1b esophageal carcinoma.
ABSTRACT
Objective To investigate the expression of hepatocyte growth factor (HGF) and its receptor c-Met in colorectal cancer tissues and their clinical significances.Methods 100 patients with colorectal cancer who accepted treatment from March 2012 to 2015 February were collected.The immunohistochemical method was used to test the expression of HGF and c-Met in tumor tissues.The correlation of clinicopathological parameters and lymphatic microvessel density (LMVD) was analyzed.Results The positive expression rates of HGF in patients with or without lymph node metastasis were 100.0 ％ (35/35) and 41.5 ％ (27/65),the difference had statistical significance (x2 =6.99,P ＜ 0.05).The positive expression rates of c-Met were 94.3 ％ (33/35) and 47.7 ％ (31/65),the difference was statistically significant (x2 =7.75,P ＜ 0.05).The positive expression rates of HGF in patients with TNM stage Ⅰ + Ⅱ and Ⅲ + Ⅳ were 48.6 ％ (17/35) and 69.2 ％ (45/65),the difference had statistical significance (x2 =5.94,P ＜ 0.05).The positive expression rates of c-Met were 51.4 ％ (18/35) and 70.8 ％ (46/65),the difference was statistically significant (x2 =6.08,P ＜ 0.05).The LMVD of patients with different lymph node metastasis,tumor stage,HGF and its receptor c-Met expression were statistically different (t values were 10.19,10.08,7.50,5.07,all P ＜ 0.05).Conclusion HGF and its receptor c-Met is closely related to the development of colorectal cancer.They can help the diagnosis,and be used as new targets in the treatment of colorectal cancer.
ABSTRACT
Objective To design and implement a dynamic simulation system for medical treatments on hospital ship, the application of which can provide evidence for the tactical and technical index of the equipment and the research on medical treatments. Methods Queuing theory and discrete events imitation methods were applied to make research on how to simulate random arrival of the sick and wounded of corresponding various random pattern, organizing of medical resources and medical treatments as well as procedures and rules of medical treatments by means of establishing overall system mathematics model on condition that the amount of the wounded and different distribution of wound type was given. Results The process data and outcome data of medical treatments such as passing ratio were achieved under different running circumstances in the given time. Conclusions The system can imitate the large-scale medical treatment process which can rarely implement many times in reality, meet different needs flexibly, and provide optimization foundation to medical resources configuration on medical ships.
