The hydrothermal reaction of 1,2-dicyanobenzene with NaN3 in the presence of Cd（NO3）2 affords a novel 2D cadmium tetrazolyl-benzoate, {Cd（tzbz）（H2O）}n （H2tzbz is 2-（5-tetrazolyl）-benzoate）. The tzbz ligand is generated in situ through the [2＋3] Sharpless cycloaddition reaction and hydrolyzation. Its crystal structure was determined by single-crystal X-ray diffraction method. The crystal crystallizes in the orthorhombic system, space group Pbca with a = 9.6659（19）, b = 7.6366（15）, c = 25.964（5）A, V= 1916.5（7）A^3, Z= 8, Mr = 318.57, Dc = 2.208 g/cm^3, F（000） = 1232 and p = 2.276 mm^-1. The Cd（Ⅱ） atom is coordinated by four tzbz ligands and one water molecule to form a severely distorted pentangle bipyramid. While each tzbz ligand connects to four Cd（Ⅱ） atoms in a μ4-η1, η, η1, η1, η1 coordination mode to construct a 2D architecture of the title complex. Additionally, the title complex exhibits strong fluorescence at room temperature in the solid state.

The hydrothermal reaction of 1,2-dicyanobenzene with NaN3 in the presence of CuC12, 2,2＇-bipyridine and H2O affords a novel dinuclear copper（Ⅱ）-ditetrazolate, [Cu（bpy）- （pdtz）]2 （Hpdtz = 5,5＂-1,2-phenylene-ditetrazole, bpy = 2,2＇-bipyridine）. The pdtz ligand is generated in situ through Sharpless 2＋3 cycloaddition reaction. Its crystal structure was determined by single-crystal X-ray diffraction method. The crystal crystallizes in the monoclinic system, space group P211n with a = 8.2096（16）, b = 18.580（4）, c = 11.838（2） A, β = 103.12（3）°, V = 1758.5（6） A^3, Z = 2, Mr = 863.83, Dc = 1.631 g/cm^3, F（000） = 876 and μ = 1.272 mm^-1.

Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.
