Virtual reconstruction of midfacial bone defect based on generative adversarial network.

Background: The study aims to evaluate the accuracy of the generative adversarial networks (GAN) for reconstructing bony midfacial defects.

Methods: According to anatomy, the bony midface was divided into five subunit structural regions and artificial defects are manually created on the corresponding CT images. GAN is trained to reconstruct artificial defects to their previous normal shape and tested.

The Diagnostic Value of Serum L1CAM in Patients With Colorectal Cancer.

Objective: Colorectal cancer is one of the most important malignant cancer in the world with high incidence and mortality. Some studies have found that the expression of low serum L1 cell adhesion molecule is associated with poor prognosis in some malignancies. It is suggested that L1 cell adhesion molecule is a candidate serum marker for certain tumors.

Arteriovenous Graft for Hemodialysis: Effect of Cryotherapy on Postoperative Pain and Edema.

Background: Arteriovenous grafting offers an alternative for patients whose vessels are unsuitable for arteriovenous fistula. However, as a result of subcutaneous tunnel dissection, postoperative pain and edema of the operated limb present early after surgery. As a traditional therapeutic approach, cryotherapy has the ability to suppress postoperative pain and edema.

Cryotherapy Relieves Pain and Edema After Inguinal Hernioplasty in Males With End-Stage Renal Disease: A Prospective Randomized Study.

Context: Tension-free hernioplasty under local anesthetic infiltration is a reasonable choice for end-stage renal disease patients with hernia.

Objectives: The purpose of the study was to investigate the feasibility of cryotherapy after hernioplasty surgery to relieve pain and scrotal edema.

Methods: This was a prospective, randomized, and controlled trial held in a large integrated health care facility in South China.

[cDNA microarray-based screening of differentially expressed genes in macrophages in the spleen of patients with portal hypertension and hypersplenism].

Objective: To identify the differentially expressed genes associated with hypersplenism in patients with portal hypertension.

Methods: The total RNA were extracted from the macrophages isolated from normal spleen and the spleen of patients with portal hypertension and reversely transcribed to cDNA with the incorporation of fluorescent (cy3 and cy5)-labeled dCTP to prepare the hybridization probes. After hybridization of Biostar-H140s chip containing 14,112 spots of cDNAs with the prepared probes, the gene chip was scanned for fluorescence intensity to screen the differently expressed genes.

[Microscopic autofluorescence study of cardiac cancer and normal gastric tissues].

Objective: To investigate the microscopic autofluorescent characteristics of cardiac cancer and autofluorescence distribution in different layers of gastric tissues.

Methods: A double-channel laser scanning confocal microscopy with Argon ion laser (excitation wavelength 488 nm) and Helium-Neon laser (excitation wavelength 543 nm) were used to detect the autofluorescence emitted from 16 surgical specimens of cardiac cancer and corresponding normal gastric tissue. The autofluorescence image was analyzed between the cardiac cancer tissue and normal gastric tissue.

Epstein-Barr virus in hepatocellular carcinogenesis.

Aim: In recent years, studies have suggested that Epstein-Barr virus (EBV) is associated with HCC. The present study was to determine the prevalence of EBV in HCC patients, and whether EBV acted synergistically with hepatitis viruses in HCC carcinogenesis.

Methods: Liver tissue 115 HCC patients and 26 non-carcinoma patients were studied.
