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. CONCLUSIONS CQCQD can up-regulate the expression of pancreatic SERCA2 mRNA, release the calcium overload, and hence reduce the pathological changes in pancreatic tissue.

D010195 Pancreatitis INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.

D011897 Random Allocation A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects. Randomization,Allocation, Random
D002108 Ceruletide A specific decapeptide obtained from the skin of Hila caerulea, an Australian amphibian. Caerulein is similar in action and composition to CHOLECYSTOKININ. It stimulates gastric, biliary, and pancreatic secretion; and certain smooth muscle. It is used in paralytic ileus and as diagnostic aid in pancreatic malfunction.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
