China Pharmacy 2005;0(23):-
OBJECTIVE: To study the endosomatic pharmacokinetics and bioequiavailability of kushenin tablets in health adults. METHODS: The blood concentrations of the blood samples taken from 22 healthy volunteers were determined by HPLC-MS after a single oral 0.3g kushenin (either tablet or capsule) dose and pretreatment with the internal standard (cimetidine) with m/z 265 (kushenin) taken as the detection ions and m/z 253 as the internal standard. RESULTS: The main pharmacokinetic parameters of the tablet and capsule of kushenin were as follows: t1/2 stood at (2.30?1.09)h and (1.90?0.58) h, respectively; tmax stood at (1.86?0.74)h and (1.68?0.55) h, respectively; Cmax stood at (525.09?208.94)ng/ml and (530.32?202.04) ng/ml, respectively; AUC0~11 stood at(2 048.5?749.4)(ng?h)/ml and (2 042.0?743.0)(ng?h)/ml, respectively;AUC0~∞ stood at(2 163.2?783.1)(ng?h)/ml and (2 136.4?792.1)(ng?h)/ml, respectively. The relative bioavailability of the kushenin tablet stood at (101.06?9.41) %. CONCLUSION:The tablet and capsule of kushenin were bioequiva_lent.
4.Mechanism of NLRC5 in diffuse large B-cell lymphoma
Journal of International Oncology 2015;42(2):157-160
Diffuse large B-cell lymphoma (DLBCL) is the most common malignant lymphoma in China,which mostly starting from the lymph nodes.The studies find that the expression of NLRC5,member of nucleotide-binding oligomerization domain-like receptor (NLR) family,is evident in the lymphoid cells,which is likely to be an important basis for lymphocyte tumorigenesis.NLRC5 can block the nuclear factor-κB (NF-κB),a core component of signal transduction pathway,and affect the development of tumor.While continuing activation of NF-κB is a necessary condition for DLBCL cell survival.Therefore,NLRC5 is likely to inhibit excessive inflammation,thereby inhibiting the function of DLBCL,which promises to be a new target for immunotherapy treatment of DLBCL.

Objective To observe the expression of pancreatic K_(ATP) channels (Kir6.2/SUR1) in rats with chronic pancreatitis and explore the intervention of nateglinide on the changes.Methods Wistar rats were induced to suffer from chronic pancreatitis and then randomized into model group, nateglinide group and control group.Then OGTT of them were observed.RT-PCR was used to detect the expression of Kir6.2 and SUR1 mRNA, and western blot to detect the expression of Kir6.2 and SUR1 proteins.Results Model rats displayed impaired glucose tolerance (IGT).The expression of Kir6.2 and SUR1 in model group decreased significantly(P<0.05), and nateglinide displayed up-reg-ulation to the expression in some degree.Conclusion The expression of pancreatic K_(ATP) channels in rats with chronic pancreatitis diminished, which might be the important mechanism of the development of pancreatogenic diabetes.Nateglinide can up-regulate the expression in some degree, which indicates that it may have latent effect of ameliorating the prognosis of patients with chronic pancreatitis.

Objective To investigate the role of mitochondrial respiratory chain (MRC) in induction of reactive oxygen species (ROS) by hyperbaric oxygen (HBO).Methods Superoxide anion (O·-2) specific fluorescence probe DHE and mitochondrial O·-2 probe Mito-SOX were used to label ROS in human umbilical vein endothelium cells(HUVEC) microscopically after HBO exposure.Results After HBO exposure, O·-2 increased (31±8)% and (137±19) % in whole cells and in mitochondria, respectively (P<0.01).These increments were suppressed by MRC complex Ⅱ inhibitor TTFA for (55±11)% in whole cells (P<0.05)and (61±8) % in mitochondria(P<0.01).Conclusion MRC may be the main source of ROS induced by HBO in HUVECs.
