BACKGROUND: Severe acute pancreatitis (SAP) is a commonly seen acute abdominal syndrome characterized by sudden onset, rapid progression and high mortality rate. The damage in peripheral organs may be more severe than that in the pancreas, and can even lead to multiple organ dysfunction. It is critical to recognize early pathological changes in multiple organs. This study aimed to assess the early pathological features of damaged organs in a rat model of SAP. METHODS: Thirty clean grade healthy male Sprague-Dawley rats weighing 250-300 g were randomly divided into a model control group (n=15) and a sham-operated group (n=15). The SAP rat model was induced by sodium taurocholate. Samples of blood and from multiple organs were collected 3 hours after operation. We assessed the levels of IL-6, TNF-alpha, PLA2, NO, ET-1, MDA, amylases and endotoxin in blood and observed the early pathological changes in multiple damaged organs. RESULTS: Levels of IL-6, TNF-alpha, PLA2, NO, ET-1 and MDA in serum and of amylase and endotoxin in plasma of the model control group rats were significantly higher than those of the sham-operated group (P<0.01). Different degrees of pathological change were observed in multiple damaged organs. CONCLUSION: Multiple organ injury may occur at the early stage of SAP in rats.

We tried to develop an efficient strategy to isolate geniposide from Gardenia fruit and use it to treat chronic pain. Eight extraction solvents and three extraction methods were respectively compared with each other for the efficiency of geniposide extraction from Gardenia fruit. Extraction with 80% ethanol under reflux was found to give the highest yield of geniposide. Orthogonal experiment was conducted to optimize the reflux conditions and the optimal conditions are a mass（of Gardeniajasminoides Ellis powder） to volume（of solvent, 80% ethanol） ratio of 1：7 and reflux twice for 60 rain each. The geniposide obtained by the reflux method was tested on the rats with chronic constriction injury（CCI） for pain relief. The results show that geniposide can enhance pain threshold and relieve pain via repressing tumor necrosis factor-a（TNF-a） expression in either ipsilateral or contralateral dorsal root gan- glion（DRG） cells. These results suggest that geniposide treatement may be an effective clinical method to relieve pain based on the mechanism of molecular biology at DRG due to nerve injury.

The interaction of Co with ceria thin films and its influence on the sintering behavior of Au were investigated by scanning tunneling microscopy（STM）, synchrotron radiation photoemission spectroscopy（SRPES） and X-ray photoelectron spectroscopy（XPS）. The strong interaction between Co and CeO_2（111） leads to oxidation of Co to Co^（2＋） at 300 K, accompanied by partial reduction of ceria surface at low Co coverages. Subsequent Co deposition results in an increasing fraction of metallic Co. Annealing to high temperatures induces Co^（2＋）ions diffuse into the CeO_2 film, while the small metallic Co islands agglomerate into larger ones. The bimetallic Co–Au particles were prepared by deposition of Au on the existing Co particles on ceria surfaces. The sintering behavior of Co–Au bimetallic surfaces is found to be highly determined by the stoichiometry of ceria supports. The addition of Co to the Au/CeO_2 surface suppresses the sintering of Au particles at high temperatures in comparison with that of pure Au particles. However, Au particles are less stable on the Co/CeO_（1.82） layer than on CeO_（1.82） surface.

The pathological processes of Alzheimer's disease and type 2 diabetes mellitus have been demonstrated to be linked together. Both PDE9 inhibitors and PPARγ agonists such as rosiglitazone exhibited remarkable preclinical and clinical treatment effects for these two diseases. In this study, a series of PDE9 inhibitors combining the pharmacophore of rosiglitazone were discovered. All the compounds possessed remarkable affinities towards PDE9 and four of them have the IC_(50) values 5n mol/L. In addition, these four compounds showed low cell toxicity in human SH-SY5Y neuroblastoma *** 11a, the most effective one, gave the IC_(50) of 1.1 nmol/L towards PDE9, which is significantly better than the reference compounds PF-04447943 and BAY 73-6691. The analysis of putative binding patterns and binding free energy of the designed compounds with PDE9 may explain the structure–activity relationships and provide evidence for further structural modifications.
