With the development of virtual reality, augmented reality, and mixed reality technology, their application in medical education has become increasingly widespread. With the advantages of virtuality-reality combination, real-time interaction and exact registration, mixed reality technology is expected to improve the drawbacks of traditional medical education, and exerts great potential in virtual classroom, virtual laboratory, anatomy teaching, medical operation training, surgery simulation, and telemedicine education. This article mainly introduces the applications of mixed reality technology in medical education in recent years, and hopes to provide a reference for the integration of mixed reality technology into the field of education.

Aim To evaluate the short-term biocompatibility of a newkind of prosthetic nucleus-Evergel, which is made from the modifiedpolyvinyl alcohol hydrogel. Methods According to China national standardGB/T16886 documents, the toxicity of Evergel prosthetic nucleus materialwas investigated by the cytotoxicity test, sensitization test, haemolysis test,Ames test, mice marrow micronucleus test and chromosome aberration test ofmammalian cell in vitro. Results This material had no cytoxicity, no sen-sitivity, no obvious haemolysis, and no mutagencity in Ames test, micemarrow micronucleus test and chromosome aberration test of mammalian cellin vitro. Conclusion The Evergel prosthetic nucleus has a good biocom-patibility and can be used clinically.

Hepatocellular carcinoma is one of the most common malignancies of liver cancer.Partial hepatectomy and liver transplantation are potentially curative treatments in patients with hepatocellular carcinoma.However,the postoperative tumor recurrence rate is high with poor long-term survival outcome.Studies have shown that the presence of microvascular invasion is an independent risk factor of post-resection prognosis.Therefore it draws attention that whether postoperative TACE can prevent the recurrence of liver cancer.This article reviews the research progress postoperative TACE effect on hepatocellular carcinoma patients with microvascular invasion,in order to provide the reference for selection of further treatment.

Objective:To evaluate the efficacy of splenic artery ligation on liver function recovery and hypersplenism in liver transplant patients with end-stage liver disease complicating portal hypertension and hypersplenism.Methods:From Jan 2016 to Jan 2019, the clinical data of patients undergoing liver transplantation at our hospital were analyzed retrospectively, among which 53 patients were enrolled in the study with end-stage liver disease complicated with portal hypertension and hypersplenism. Patients were divided into ligation group( n=23) and no ligation group( n=30). The serum liver function and white blood cells, platelets and postoperative complications were compared. Results:20 pairs of patients were successfully matched by PSM method. All patients were followed up for over 6 months.There was no statistically significant difference between the two groups in all the observation points within 2 weeks after operation; Within 6 months, there was no statistically significant difference in WBC, platelet and Hgb.Statistically significant differences in postoperative complications such as infection, gastrointestinal bleeding, and splenic artery stealing syndrome were also not found between these two groups.Conclusions:Splenic artery ligation during liver transplantation does not accelerate liver function recovery nor ameliorate hypersplenism.
