OBJECTIVE: To investigate the protective effects of Chaiqin Chengqi Decoction (CQCQD), a compound traditional Chinese herbal medicine, on acinar cells and the changes of intracellular calcium concentration ([Ca(2+)]i) in acute pancreatitis (AP) rats. METHODS: CQCQ serum (CQCQS) was prepared by intragastric administration of CQCQD in SD rats, and AP was induced in SD rats by biliary-pancreatic duct ligation method. Pancreatic acinar cells were isolated by collagenase digestion and co-incubated with the drug serum containing CQCQD in vitro, then cell viability was determined by methyl thiazolyl tetrazolium (MTT) method and intracellular fluorescent intensity (FI) was observed and analyzed to investigate the changes of intracellular calcium concentration ([Ca(2+)]i). RESULTS: Both 5% and 10% CQCQS could improve the viability of pancreatic acinar cells in AP rats (P<0.05), and 10% CQCQS was more effective than 5% CQCQS (P<0.05). [Ca(2+)]i was elevated in AP rats (P<0.05), while the level of [Ca(2+)]i elevation was reduced after CQCQS treatment (P<0.05). CONCLUSION: CQCQD has a protective effect on pancreatic acinar cells of AP rats, which may be associated with its inhibition effect on intracellular calcium overload.

OBJECTIVE: To investigate the therapeutic effect of Yihuo Qingxia method, a traditional Chinese medicine therapeutic method for replenishing qi to activate blood, clearing away heat and dredging intestines, in treating hyperlipoidemia-related severe acute pancreatitis (SAP) in early stage. METHODS: One hundred and four patients with hyperlipoidemia-related SAP were divided into two groups: early group (admitted to hospital within 3 days after onset) and late group (admitted to hospital from 3 days to 7 days after onset). There were 52 cases in each group. All the patients were treated by Yihuo Qingxia method. RESULTS: There were no statistical differences in 48-hour Ranson scores, CT scores, 24-hour acute physiology and chronic heath evaluation II scores (APACHE II scores), and the levels of 24-hour serum triglyceride (TG) and serum glucose in the two groups (P>0.05). At the 10th day after onset, the serum TG level in early group was lower than that in late group (P<0.01). The incidences of acute respiratory distress syndrome, acute renal failure, hepatic inadequacy, congestive heart failure, shock, encephalopathy, infection and alimentary tract hemorrhage in early group were higher than those in late group (P<0.05). The mortality in early group was lower than that in the late group (P<0.05). The length of hospital stay in early group was shorter than that in late group (P<0.05). CONCLUSION: Yihuo Qingxia method has a good efficacy in treating hyperlipoidemia-related SAP in early stage.

AIM: To study the effect of focal adhesion kinase (FAK) phosphorylation on the adhesion and migration of smooth muscle cells (SMCs) stimulated by fibronectin (FN). METHODS: Cultured SMCs were stimulated by different concentrations of FN.FAK expression and phosphorylation were detected by immunoprecipitation and Western blot. To investigate the modulating effect of FAK on tyrosine phosphorylation and SMCs adhesion and migration, FAK antisense oligodeoxynucleotides (ODNs) were transfected into SMCs by actionic lipid method. RESULTS: FAK expression increased when SMCs adhesion and migration were induced by FN at different concentrations used in the experiment. However, FAK phosphorylation was only observed by FN stimulation at concentration of 20 mg/L. FAK antisense ODNs inhibited FAK phosphorylation magnificently. The migration rates of SMCs were reduced by 17.89%-27.67% when FN was used at concentration from 5 mg/L to 60 mg/L. The decreased migrating cell numbers were showed the same patterns. The apoptotic SMCs were 33.57% higher than that control ( P

OBJECTIVE: To investigate the mechanism of Chaiqin Chengqi Decoction (CQCQD), a compound of traditional Chinese herbal medicine, acting on the pancreatic acinar cell calcium overload in rats with acute pancreatitis (AP). METHODS: A total of 30 SD rats were randomly divided into normal control group, untreated group and CQCQD group (n=10, respectively). AP was induced in rats by caerulein (5x50 mug/kg) intraperitoneal injection within 4 h. The pancreatic tissue SERCA1 and SERCA2 mRNA expressions were detected by fluorescent quantization polymerase chain reaction method; intracellular calcium fluorescence intensity (FI) of pancreatic acinar cells and the pancreatic pathological score were measured by laser scanning confocal microscopy and light microscopy respectively. RESULTS: There were no SERCA1 mRNA expressions in pancreatic acinar cells of rats in the normal control group and the untreated group. The expression of pancreatic SERCA2 mRNA in the untreated group was down-regulated compared with that in the normal control group (expression ratio=0.536; P=0.001); the expression of pancreatic SERCA2 mRNA in the CQCQD group was up-regulated compared with that in the untreated group (expression ratio=2.00; P=0.012). The pancreatic pathological score in the CQCQD group was lower than that in the untreated group and the FI of Ca(2+) was also lower. CONCLUSION: CQCQD can up-regulate the expression of pancreatic SERCA2 mRNA, release the calcium overload, and hence reduce the pathological changes in pancreatic tissue.

OBJECTIVETo study the effects of focal adhesion kinase (FAK) phosphorylation on smooth muscle cells (SMCs) adhesion and migration stimulated by fibronectin.

METHODSAdhesion and migration of cultured SMCs were stimulated by different concentrations of fibronectin (FN), FAK and its phosphorylation were detected by immunoprecipitation and Western blot. FAK antisense oligodeoxynucleotides (ODNs) were transfected into SMCs by cationic lipid to investigate its modulatory effects on tyrosine phosphorylation. SMCs adhesion and migration were also measured by morphological enumeration and modified Boyden Chambers, respectively.

RESULTSFAK were expressed when SMCs adhesion and migration were successfully simulated by different concentrations of FN. FAK phosphorylation were detected only at 20 microg/ml FN or more. FAK antisense ODNs were transfected efficiently by cationic lipid and FAK phosphorylation was inhibited substantially. The SMCs migration rate in the 5 - 60 microg/ml FN groups was reduced by 17.89% - 27.67%. Cell migration stimulated by FN at 10, 20, 40 and 60 microg/ml were reduced by 23.26%, 21.63%, 19.31% and 17.88%, respectively (P < 0.05).

CONCLUSIONSFAK phosphorylation and FAK-mediated signal transduction play important roles in SMCs adhesion and migration stimulated by ECM. The process can be inhibited effectively by FAK antisense ODNs.
