Objective To observe the synapse formation in hippocampal dentate gyrus, and the memory ability after transplanting bone marrow stromal cells (BMSCs) into lateral ventricle of ischemic brain injury rats. Methods BMSCs from femur of a Sprague-Dawley rat were cultured for 3 generations in vitro. 60 newborn Sprague-Dawley rats were divided into sham group (n=20), model group (n=20) and BMSCs group (n=20). The latter 2 groups were ligated the left common carotid artery, and the BMSCs group were injected BMSCs into the lateral ventricle 7 days after ligation. They were tested with Morris's water maze 8 weeks later, and then, the brains were immunohistochemical staining to detect synaptophysin (SY). Results The time of probe trial of acquisition phase (T1) and reveral phase (T2) decreased in the model group compared with the sham group (P<0.05), and increased in the BMSCs group compared with the model group (P<0.05). The integral optical density (IOD) of SY positive cells decreased in the model group compared with the sham group (P<0.05), and increased in the BMSCs group compared with the model group (P<0.05). Conclusion BMSCs implantation through lateral ventricle can improve the learning and memory ability of rats, which may associated with the synapse formation in dentate gyrus.

This paper summarize the perioperative nursing of 12 newborns with thyroglossal cyst. The preoperative nursing measures focused on prone position,gastric tube feeding,close monitoring of vital signs and tracheal intubation as needed. If the TeSO2 was normal,oxygen therapy was not recommended. After the operation,continuously monitoring vital signs,respiratory care and use of sedatives as needed were carried out. As a result,all of the 12 infants recovered and discharged.

OBJECTIVETo promote development and utilization of Ophiocordyceps gracilis in xinjiang and provide basic data for researching and sustainable developing medicine fungus related to O. gracilis.

METHODA white strain SFYT002 isolated from the sclerotium of O. gracilis in Xinjiang was researched by morphological observation, ITS and 18SrDNA sequencing. The ITS and 18SrDNA sequences of the strain were determined, BLAST was compared with the other sequences of Tolypocladium in GenBank. The phylogenetic trees of ITS and 18SrDNA sequences were analyzed in Tolypocladium. In addition, the filter paper method was used to study the antibacterial effects.

RESULTThe main morphological characters of this strain were white cotton-like colonies, phialide with inflated base, drastically sharping with partially bending tips, small and transparent budding spores with being always assemble to spearhead and globular, subglobular or ellipse conidiospores. The phylogenetic trees of ITS and 18SrDNA sequences were constructed and analyzed in Tolypocladium. It was resulted that Tolypocladium was confirmed to be monophyletic, and the strain SFYT002 was the same as the systematic position of others of T. inflatum. Meanwhile, the antibacterial test was performed against the 4 common pathogenic bacteria. It was showed that both fermentation and its extracts of different polar from this strain possessed good anti-bacteria capacities.

CONCLUSIONThe strain SFYT02 was identified as T. inflatum, and inhibited effectively growth of bacteria.

Objective To investigate etiology and clinical features of acute pancreatitis (AP) in young patients. Methods In total, 423 patients with AP admitted to Renmin Hospital of Wuhan University, Wuhan, Hubei province during January 2006 to December 2009 were retrospectively analyzed, 55 cases aged 34 years or less as young group and another 55 cases aged more than 34 years as middle- and elderly-age group. Their etiology, clinical features and illness scores based on some standard criteria were assessed. Results Proportion of varied etiologies of AP in young group was different from that in middle- and elderly-age one (x2 = 17. 107, P = 0. 009) , mainly as biliary and idiopathic pancreatitis in young group and as biliary and alcoholic pancreatitis in middle- and elderly-age one. Incidence of diet-related and idiopathic pancreatitis were higher in young group than that in middle- and elderly-age one ( x2 =4. 853, P = 0. 028 and x2=4. 274, P = 0. 039 ). Scores of the acute physiology and chronic health evaluation II ( APACHE II ) , Ranson criteria and the bedside index for severity in acute pancreatitis ( BISAP) were all lower in young group than those in middle- and elderly-age one (t = 5. 381 , P = 0. 000; t = 4. 388 , P = 0. 000 and t=3. 083, P = 0. 003 ) . There was no statistically significant difference in scores of computed tomography severity index ( CTSI) between young group and middle- and elderly-age one (t = ±0. 750, P > 0. 05 ) . Recurrence rate of AP was lower in young group than that in middle- and elderly-age one ( x2 =4. 251, P = 0. 039). Cholecystitis was more complicated in young group, pregnancy was more complicated in young group (x2 =4. 151 , P =0. 042) , and elevated blood glucose was more complicated in middle- and elderly-age one (x2 = 13. 285 , P = 0. 000 ) . Conclusions Etiology of AP varies in young patients with more dietary factors, occurrence of systemic complications and risks for death are lower in young group than those in middle- and elderly-age one, and there was no statistically significant difference in local complications and severity of illness between the two groups.
