Objective To establish a Chromatin immunoprecipitation assay to analyze transcriptional regulation of gene expression in hepatocytes. Methods The PEPCK gene was used as a target gene, HPRT, MBP and IgG were used as internal reference, the chromatin immunoprecipitation and PCR were performed with antibody specific for CREB to verify bindings of transcription factor CREB to the PEPCK promoter under various metabolic conditions. Results Transcription factor CREB occupies its target sites in the PEPCK promoter and this binding is increased by 4-fold during fasting in the anti-CREB antibody immunoprecipitated DNA fragments. Conclusion The results confirm that CREB binds to the PEPCK promoter and is involved in transcriptional regulation of PEPCK gene in hepatocytes.

OBJECTIVE: To observe the effects of long-term administration of pioglitazone at different doses on the expression of glucose transporter-4(GLUT-4) of cardiac muscle tissue in rats and to discuss the possible mechanisms.METHODS: A total of 40 Wistar rats were enrolled,of which,10 were randomly assigned to normal control group(NC),and the other 30 were injected intraperitoneally with streptozotocin to establish diabetes mellitus(DM) rat model.After successful modeling,the rats were assigned to DM model group(DM,normal saline),high and low dose pioglitazone group(HP,LP;0.75,0.25 mg?kg-1?d-1).The NC groups received normal saline for 12 weeks.Blood glucose(BG) level before grouping(baseline level) and prior to death was determined by tail-cutting method.GLUT-4 level in cardiac muscle tissue and both protein and mRNA expression of AMPK? were determined by RT-PCR and western blot,respectively.RESULTS: As compared with NC group,the BG level in DM group was significantly increased but the expression of GLUT-4 and AMPK? decreased significantly(P

Objective To comparatively analyze the results of the PT derivative method and the Clauss method for detecting fi-brinogen(Fib) by the automated coagulation analyzer and to explore their accuracy and clinical value .Methods Fib was detected in 156 blood samples selected from the patients in this hospital from March to May 2013 ,25 normal control samples and 13 positive samples of D-dimer (DD) by the TP derivative method and the Clauss method .Results The Clauss method and the PT derivative method by Sysmex CA-1500 coagulation analyzer had good repetitive rate in measuring Fib for 25 times ;when Fib<1 .0 g/L ,the results detected by these two methods had statistically significant difference (P<0 .05);when Fib in the range of 1 .0 -2 .0 g/L , 2 .1-3 .0 g/L ,3 .1-4 .0 g/L ,the detection results had no statistically significant difference between the two methods (P>0 .05);when Fib in the range of 4 .1 -5 .0 g/L ,the detection results had statistically significant difference (P<0 .05);when Fib>5 .0 g/L ,the detection results had statistically significant difference (P<0 .05);in 13 DD positive samples ,the detection results of the PT derivative method were significantly higher than those of the Clauss method with statistically significant difference (t=8 .530 , P<0 .05) .Conclusion The difference exists between the PT derivative method and the Clauss method for detecting Fib ,but the ac-curacy of the Clauss method is higher than its specificity ,the Clauss method should be the first choice for the clinical determination of plasma Fib .

[ Objective ] To evaluate the significance of high-frequency ultrasonography (HFU) combined with color Doppler velocimeter (CDV) for the differential diagnosis of breast masses (BM) . [Methods] HFU and CDV findings in 113 cases of BM were compared with their pathological findings. [Results] There was a certain relationship between HFU findings and pathological findings. The detectable rate for the blood flow accounted 97.80% in breast cancer examined with HFU, resistance index (RI) being 0.77?0.06; detectable rate for benign BM was 61.76%, RI being 0.52?0.05. The difference was significant between the two detectable rates (P

Objective To discuss the implication of ectopic opening of the pancreaticobiliary duct in the performance of cholangiopancreatography (ERCP) and the diagnosis and treatment of cholangio-pancreatic disease. Methods We summarize the data of 1000 cases of ERCP in the past four years. Five patients were found with ectopic opening of the pancreaticobiliary duct. The positions, characteristics of ectopic opening and the characteristics of the mucosa disease around the ectopic papilla and cholangio-pancreatic disease were analyzed. Results In the 5 patients with ectopic opening of the papilla, one had the opening in the pyloric channal, two in the duodenal bulb, the other two in the distance of the descending part of duodenum. Mucosa erosion was found in the patients with ectopic opening in the pyloric channal and in the duodenal bulb. Conclusion The ectopic opening of the pancreaticobiliary duct may affect the finding of the papilla, but may not affect the performance of ERCP. The incidence of the cholangiopancreatic disease and the mucosa disease around the ectopic papilla will increase in the patients with ectopic opening.

Routine vaccination is a most important way to prevent and control various kinds of infection disease,however,concerns about epileptic diseases after vaccination worries patients and health care providers.Many studies have shown that the risk of febrile seizure(FS)increases after measles-mumps-rubella(MMR)and iphtheria-tetanus-pertussis(DTP)vaccine,but this increase is associated with the fever after vaccine.The prognosis of vaccine related FS is similar to non-vaccine FS.Moreover,no evidence has shown that vaccine is related with non-febrile seizure and epileptic encephalopathy.

Objective To optimize the extraction technology of Morchella polysaccharide.Methods With GIM5.69(Morchella esculenta(L.) Pers.) and GIM5.29(Morchella elata) as the research object,the difference of polysaccharide yield with lixiviation in polysaccharide extraction between ultrasound and enzyme was observed.At the same time,the difference of polysaccharides yield of these two Morchella was compared.Result Ultrasound and enzyme both can improve the polysaccharides yield,and the effect of 10 min of ultrasound was the best.The polysaccharides yield of GIM5.69 was higher than that of GIM5.29,which means different strain has different polysaccharides yield.Conclusion The best extraction condition is 10 min of ultrasound at the frequency of 40 kHz,heating 150 min at 90 ℃ and lixiviation twice.
