3.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.

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.

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 evaluat physical exercise's effct on left ventricle diastolic function.Methods 12 college athletes and 12 students' transmital flow volume in peace state were measured and analysed. Results College athletes' MV VTI is bigger, MEAD GRAD and A are smaller.Conclusion Physical exercise can improve the brimming and unhindering abilities of left ventricle and increase the area of mitral valve.

Objective To compare the clinical effects of four kinds of gingival retraction technique in treat-ment of anterior teeth restoration.Methods 169 patients for 352 teeth with tooth body and tooth dentition defect by anterior crown bridge repair were chosen and divided into 4 group by patients'order,including A group(88cases)with single track method,B group(91cases)with single line for two times method,C group(89cases)with double line method and D group(94cases)with double line for two times method.And the fixed restoration satisfaction rate of anterior teeth of both groups was compared.Results The satisfaction rates of gums,shoulder,impression,model and restoration of A group were 73.9%,70.1%,69.3%,65.9%,61.4% respectively,which of B group were 83.5%, 80.2%,80.2%,80.2%,76.9%;which of C group were 84.3%,80.9%,78.7%,77.5%,76.4%;which of D group were 94.6%,93.6%,92.6%,92.6%,90.4%.There were no significant differences in the fixed restoration satisfaction rate of anterior teeth between B group and C group(χ2 =2.43,1.17,2.85,3.04,2.30,all P >0.05). The fixed restoration satisfaction rate of anterior teeth of D group were significantly better than A,B and C groups (χ2 =14.90,16.39,15.83,19.87,21.38,all P <0.05 ).Conclusion Double line for two times method in the treatment of anterior teeth restoration can efficiently avoid ree gingival damage in the situation with abutment shoulder preparation,improve the quality of preparation,impression and model,and are helpful to higher the fitness of the neck of anterior teeth fixed restorations.
