Methods： Dynamic observation of 3 cases of liver transplantation recipients of HCC and cirrhosis, which developed manifestations of fever, skin rash, watery diarrhea, pancytopenia and were finally diagnosed as aGVHD. Two of which got recovered from intravenously pulse methylprednisolone, high-dose intravenous immunoglobulin, antibiotics administration simultaneously and promptly withdrawal of oral immunosuppressants. Two survivors were follow-up regularly with biological monitoring and imaging surveillance for tumor recurrence thereafter. Results： Two recipients survived healthily with stable liver graft function and normal serum AFP level and blood routine test. No sign of tumor recurrence was found in repeat imaging examinations for liver graft, lung, brain and other tissue or organs within a period of 96 months and 17 months to date, respectively. Conclusien： Despite of the fatal damage to according organs and tissue, it suggest that aGVHD in liver recipients of HCC may also develop a GVT effect and benefit prophylaxis of tumor recurrence and result in a long-term healthy recipients survival.展开更多

A key to genera within this new family is provided. All specimens described were collected from the Middle Jurassic Jiulongshan Formation of Eastern Inner Mongolia, China. The present discovery demonstrates that present knowledge of the Jurassic Neuropetra fauna remains very poor. The fossil specimens are deposited in Yizhou Fossil Museum and Department of Biology, Capital Normal University, respectively.展开更多

The effect of NB on the pharmacokinetics of Ge in rat via intranasal administration was investigated. The concentrations of Ge in plasma were determined by reversed-phase high-performance liquid chromatography （HPLC） after intranasal administration of Ge （4 mg/kg） alone and combined with different doses （0.08, 0.8, and 8 mg/kg） of NB. The intravenous administration was given as a reference （4 mg/kg of Ge and 8 mg/kg of NB）. Compared with the intravenous administration, the absolute bioavailability of Ge was 76.14% through intranasal administration combined with NB. Compared with the intranasal administration of Ge alone, Ge could be absorbed rapidly in the nasal cavity combined with NB; the peak time of Ge in the plasma became shorter （3-5 min vs. 40 min）; the peak concentration became higher （1.32-4.25 IJg/ml vs. 0.67 ug/ml）; and, the relative bioavailability of Ge combined with NB was 90.3%-237.8%. The enhancing effect was attenuated as the dose of NB decreased. The results indicated that NB can accelerate the absorption of Ge dose-dependently in the nasal cavity.展开更多
