OBJECTIVETo investigate the protective effect and mechanism of Xingnaojing(Traditional Chinese Medicine) injection on brain injury in rats.

METHODSSixty-three healthy adult male SD rats were randomly divided into 3 groups (n = 21): sham operation group, model group, xingnaojing group. The model of traumatic brain injury model group and Xingnaojing group used the free fall impact injury method, the sham operation group underwent craniotomy, did not cause brain damage. Xingnaojing group in rats after 10 min by tail vein injection Xingnaojing injection 10 ml/(kg x d), model group and sham operation group were intravenously injected with 0.9% sodium chloride solution, three groups were administered continuously for 7 days. At administration of the seventh days compared the S-100B protein in the serum and neuro specific enolase (NSE) level, the water content of brain tissue, serum superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) content, and neurological function of rats among groups.

RESULTSCompared with the sham operation group, the nerve defect, brain water content, MDA, S100B protein and NSE levels were obvigusly increased in Xingnaojing group and model group; SOD, GSH-Px content decreased significantly; In Xingnaojing group nerve impairment and brain moisture were significantly lower than those of model group, the serum MDA, S-100B protein and NSE levels were significantly lower than those in the model group, the SOD, GSH-Px activity was significantly higher than that in the model group.

CONCLUSIONXingnaojing injection has protective effects on rat brain injury, and its mechanism may be related to reduce brain edema after traumatic brain injury and inhibit the reaction of oxygen free radical, protect nerve cells.

Embryonic stem cells(ESCs) are pluripotent cells derived from the inner cell mass of blastocyst-stage embryos, possessing permanent self-renewal and indefinite proliferative capacity in vitro. And ESCs could differentiate into the hematopoietic cell fate. Therefore ESCs may provide an alternative for hematopoietic stem cell transplantation and blood cells transfusion. Furthermore, ESCs differentiation could also provide a powerful model system to better understand the hematopoietic development and the mechanism involved. The current status for efforts to differentiate ESCs into hematopoietic lineages were reviewed.

Nucleotide-binding oligomerization domain containing protein 2 (NOD2) is a member of intracellular pattern recognition receptor. After being activated, it will induce the release of inflammatory factors through a series of signal cascade transduction, thus playing an important role in the innate immune response. The abnormal NOD2 signaling pathway is involved in the occurrence and development of many diseases, especially the single nucleotide polymorphisms (SNPs) of the NOD2 gene have been identified to be closely associated with autoinflammatory diseases (AIDs). Therefore, inhibitors targeting NOD2 pathway have great potential in the treatment of inflammatory immune diseases. This review presents the recent progress of NOD2 receptor-mediated signal transduction pathways and its regulation mechanisms, the relationship between NOD2 and AIDs, and the inhibitors of NOD2 pathway.

Objective To investigate the diagnostic value of intraductal ultrasonography (IDUS) for unconfirmed microlithiasis under endoscopic retrograde cholangiography ( ERC). Methods The data of 22 patients who were definitely diagnosed as having microlithiasis by IDUS and endoscopic sphincterotomy (EST) from July 2007 to September 2009 were retrospectively analyzed. Microlith was defined as choledo-cholith equal to or less than 3 mm in diameter. Using IDUS plus EST findings as golden standard of bile duct microlithiasis, the accuracy of diagnosis and rate of missed diagnosis of transabdominal ultrasonography, magnetic resonance cholangiography (MRC) and ERC were evaluated and compared. Results Diagnosis rates of trans-abdominal ultrasonography, MRC and ERC for extra-hepatic duct microlithiasis were 27. 3% (6/22), 38. 5% (5/13) and 27. 3% (6/22) , respectively. Detection rates of common bile duct dilation by 3 methods were 68. 2% (15/22) , 84. 6% (11/13) and 68. 2% (15/22) , respectively. The microlithiasis in 2 patients, which manifested as repeated acute pancreatitis, were missed by transabdominal ultrasonography , MRC and ERC, and were finally confirmed by IDUS. Conclusion Sensitivity of ERC in diagnosis of extra-hepatic microlithiasis is not superior to that of transabdominal ultrasonography or MRC. IDUS is a technically easy, safe, highly sensitive and accurate procedure, which is helpful in differentiation of etiology of recurrent acute pancreatitis.

To investigate the distribution of the genes of two major metallo-beta-lactamases (MBL; i.e., IMP and VIM) and class 1 integrons (intI) in the clinical imipenem-resistant Pseudomonas aeruginosa, a total of 65 isolates, from a university hospital in Sichuan between December 2004 and April 2005 were screened for MBL genes by PCR using primers specific for bla ( IMP-1 ), bla ( VIM ) and bla ( VIM-2 ) genes. The MBL-positive isolates were further assessed for class 1 integrons by PCR using specific primers. The nucleotide sequences of several PCR products were also determined. The results revealed that the bla ( VIM ) gene was found in 81.5% (53/65) of all isolates, bla ( VIM-2 ) gene was found in only 1 isolate and the intI gene was observed in 45.3% (24/53) of bla ( VIM )-positive isolates. One isolate carried simultaneously both bla ( IMP-1 ) and intI genes, and to the best of our knowledge this is the first report of such isolate in southwest China. These observations highlight that the genes for VIM beta-lactamase and class 1 integrons were predominantly present among the imipenem-resistant P. aeruginosa tested, confirming the current widespread threat of imipenem-resistant, integron-borne P. aeruginosa.
