Liver transplantation is the most effective treatment for end-stage liver disease, and early graft dysfunction often occurs after surgery. Early liver dysfunction after liver transplantation has become one of the complications after liver transplantation, which seriously affects the graft and patient survival. Therefore, reducing its occurrence can be an important means to improve the prognosis of recipients after liver transplantation. This paper discusses the research progress on the definition, influencing factors, and prognosis and prediction model in order to provide better prevention and effective reference for improving the success rate and prognosis of early liver dysfunction in recipients after liver transplantation.

AIM: To study the effect of Salvia miltiorrhiza injection on rat atherosclerosis (AS), and elucidate the possible mechanism. METHODS: Wistar rats were fed with fat-rich diet and high dose of vitamin D_3 to induce AS, then treated with Salvia miltiorrhiza injection. Concentrations of triglyceride (TG) and total cholesterol (TC) in serum were measured by automatic serum biochemical assay. The level of ICAM-1 protein and mRNA were determined by Western blot and RT-PCR. RESULTS: Compared with the AS model group, the levels of TG and TC in serum were significantly lower in Salvia miltiorrhiza injection group (P

The incidence of colorectal cancer is high among the elderly. Traditional Chinese medicine (TCM) has been widely used in the treatment for colorectal cancer of old people. However, controlled trials with large sample size evaluating the effect of TCM are rare.

Objective:To explore the proliferation inhibition and radiosensitization of Biyanqing granule on nasopharyngeal carci -noma cell line CNE-2 in vitro.Methods:CNE-2 cells were cultured in vitro.The inhibition of Biyanqing granule on the proliferation of CNE-2 cell was evaluated by MTT assay .Radiosensitization was explored by clone formation assay , and cell cycle and apopotosis were observed by flow cytometry ( FCM) .Results:Biyanqing granule could inhibit the proliferation of CNE-2 in a time-and dose-dependent manner.The IC50 in 24, 48 and 72 h was 70.79, 60.13 and 51.63 mg· ml-1(calculated according to the weight of all medicinal ma-terial), respectively.The colony formation assay showed that Biyanqing granule combined with radiation could significantly reduce the colony formation of CNE-2 cells.With the concentration increase of the main drug , the colony formation of CNE-2 cells was reduced . The number of colony formation in the negative control group , the radiation group , 10 mg· ml-1 and 20 mg· ml-1 Biyanqing combined with radiation groups (calculated according to the weight of all medicinal material ) was significant different (P<0.05).With the main drug concentration increasing , the percentage of G 2/M phase and apoptotic cells were both increased , and compared with the con-trol group, the difference was significant (P<0.05).Conclusion:Biyanqing granule can not only inhibit CNE-2 cells but also block CNE-2 cells in G2/M to improve the radiosensitization of CNE-2 cells.

Aim To explore the role of endoplasmic re-ticulum stress( ERS) in Astragaloside Ⅳ-induced car-dioprotection against ischemia/reperfusion injury in rats. Methods A model of myocardial ischemia 30 min followed by 120 min reperfusion was made by liga-ting coronary artery in male Wistar rats. Rats were di-vided randomly into 4 groups: sham group, ischemia/reperfusion group, ERS inhibitor TUDCA group, As-tragaloside Ⅳgroup. Myocardial samples were collect-ed from the risk zones during ischemia and reperfu-sion, ERS was determined by measuring levels of glu-cose regulated protein 78 ( GRP78 ) , an established marker of ERS with Western blot. Immunofluorescence study was used to test GRP78 intensity with laser scan-ning confocal microscopy, TTC method was used to measure the infarct size,hematoxylin-eosin staining was used to observe the changes of morphological changes of myocardium. Results There was no statistical difference in GRP78 expression during ischemia com-pared to the sham group, but was markedly increased upon reperfusion. Astragaloside Ⅳ could mimic TUD-CA and significantly decreased the GRP78 expression, reduced infarct size and improved the morphology of myocardial tissue with a significant statistical difference compared with the control group ( P<0. 05 ) . Conclu-sions ERS is induced upon reperfusion but not during ischemia in isolated rat hearts. Astragaloside Ⅳ pre-vents myocardial reperfusion injury presumably by the inhibition of ERS.
