Objective To assess the value of myelography and CTM for the diagnosis of lumbar disc herniation.Methods 200 patients diagnosed as lumbar disc heriniation based on clinical findings were reported.They were all examined with myelography and CTM prior to operation.Results Based on the operative findings the accuracy was 86% in myelography and 98.5% in CTM.Conclusion CTM is more accurate than myelography in the diagnosis of lumbar disk heriniation.

Objective To investigate the long-term clinical efficacy of simplified multivisceral transplantation in patients with end-stage liver disease and type 2 diabetes.Methods The clinical data of 31 cases of simplified multivisceral transplantations between 2009 to 2017 were retrospectively analyzed.Results Median post-transplant follow-up was currently 13 ± 26 (0-86) months.Two recipients died of multiple organ dysfunction system (MODS) followed by severe sepsis on postoperative day (POD) 15 and 18,respectively.One recipient died from severe pneumonia with pyemia on POD 37.One recipient died of graft versus host disease (GVHD) on POD 40.One recipient died from acute myelogenous leukemia.Two recipients died of tumor recurrence at postoperative month (POM) 9 and 26,respectively.No biliary complication or diabetes recurrence was observed during follow-up.Condusion Donation after citizen's death is becoming the only organic source in China.Our results indicate that combined en-bloc liver-pancreas transplantation is technically feasible and leads to excellent long-term control of glucose metabolism and satisfactory quality of life in recipients with end—stage liver disease and diabetes mellitus.

Background/Aims: The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation. Methods: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles. Results: FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012). Conclusions FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.
