Objective To construct and implement theSTARnurse training model, and discuss its application effect and the problems that should be paid attention to, and to provide operational cases and practical basis for nursing clinical education. Methods Through literature review and expert consultation, the framework and content of STAR nurse training model were set up and implemented. The questionnaire survey and semi structured in-depth interviews were conducted among the nurses in the hospital to evaluate the effect of improving the nurses′self-directed learning ability. Results After the implementation of the project, the scores of the three dimensions of self-management, desire for study and self-control were (3.67±0.57), (4.05±0.54), (3.99±0.50) points, which were higher than (3.55±0.49), (3.71± 0.52), (3.53±0.42) points before implementation. The difference was statistically significant (P<0.05 or 0.01). The semi structured in-depth interviews showed that all the nurses believed that STAR nurse training model could promote independent learning and stimulate interest in learning. 14 nurses thought it was beneficial for the nurses to find the problems. Conclusions STAR nurse training model can create a favorable learning environment for nurses, and stimulate the learning motivation. It plays a positive role in improving nurses′ability of self-directed learning.

Objective To study the relationship between clinical diagnosis and children ventricular premature beat(VPB) electrocardiogram location and morph.Methods Both organic heart disease and without organic heart disease relationship with 109 cases of children ventricular premature beat electrocardiogram location and morph were retrospectively analyzed.Results Children ventricular premature beat location shows that organic heart disease mostly results from left ventricle, without organic heart disease often comes from right ventricle. There was significant difference between above two groups (? 2=37.25 P

Objective To explore the treatment of hemangioma associated with thrombopenia(Kasabach-Merritte syndrome,KMS) in infant.Methods The clinical manifestation and the therapy of 14 cases patients with KMS in hospital from 2003 to 2006 were collected ang analyzed,the 400 g/L urea(manufactured by ourself)combined with methylprednisolone local injection were used and followed 0.5 to 1.0 year.Results Two in 14 cases were emergency exairesis,7 cases were recurred for several times,12 cases were cured,1 case was improved,1 case was loss the connection.Conclusions It is an ideal therapy method to use the urea combined with glucocorticoid to treat infancy KMS,little trauma,definite effective,low side effect,high cure rate.

According to the 2010 Chinese pharmacopeia, salt processed and charcoal processed Eucommiae Cortex were pre- pared. HPLC-DAD analysis of the content of the bark and leaf of Eucommiae Cortex showed that the bark of Eucommiae Cortex mainly contained lignans such as pinoresinol glucose and iridoid including genipin, geniposide, geniposidic acid, while the leaf of Eucommiae Cortex consisted of flavonoids such as quercetin and phenolic compound such as chlorogenic acid. The content of pinoresinol diglucoside in the bark of Eucommiae Cortex was about 18 times more than that in the leaf of Eucommiae Cortex. The content of pinoresinol diglucoside in salted and charcoal processed Eucommiae Cortex decreased approximately by 30% and 85%, respectively. The content of genipin, geniposide and geniposidic acid in the bark of Eucommiae Cortex was about 3 times, 23 times, 28 times more than that in the leaf of Eucommiae Cortex. The content of genipin, geniposide and geniposidic acid in salted Eucommiae Cortex were reduced by 25%, 40% and 40%, respectively. The content of genipin, geniposide and geniposidic acid in charcoal processed Eucommiae Cortex were reduced by 98%, 70%, 70%, respectively. The content of caffeic acid in bark of Eucommiae Cortex was about 3 times more than that in the leaf of Eucommiae Cortex. The content of caffeic acid was decreased by about 50% in the salted Eucommiae Cortex. While the content of caffeic acid in charcoal processed Eucommiae Cortex was decreased approximately 75%; the content of chlorogenic acid in bark of Eucommiae Cortex was about 1/6 of that in the leaf of Eucommiae Cortex. The content of chlorogenic acid in salted and charcoal processed Eucommiae Cortex decreased by 40% and 75%, respectively; the content of quercetin in bark of Eucommiae Cortex was only 1/40 of that in the leaf of Eucommiae Cortex. The content of quercetin in salted and charcoal processed Eucommiae Cortex were reduced by 60% and 50%, respectively.

Objective To probe the effects of nuclear factor kappa B (NF-?B) on cell apoptosis and left ventricular segmental function in acute ischemia repeffusion in dogs.Method Twenty-four dogs were randomly divided into three groups:without left anterior artery (lAD) ligation group (C group),LAD was occluded 30 min following reperfusion 120 minutes in isehemical reperfusion group (IR group),and dogs were administered with PDTC before LAD ligation in ischemical reperfusion plus pyorrole dithitocarbamate group (PDTC group).The left ventricular segmental function was detected by echo cardiography using strain rate anlysis software.EF measured by Simpson's method.Cardiac myocyte apoptosis numbers were determined by terminal deoxynudeotidy transferease-mediated biotinylated deoxyuridine triphosphate nick end labeling (TUNEL).lmmunohistochemistry and western-blot anylysis of NF-?B protein expression.Results NF-?B was obviously expression on injury myocardium of IR group,and increased significantly in contrast to control group (P0.05)Conclusions NF-?B might play an important role in acute myocardial ischemia reperfusion.PDTC reduces myocardial iscbemia/repeffasion injury by preventing expression of factor NF-?B.

Saccharmyces cerevisiae 220 has certain resistance to Pb2+ was found through the test of it's cultured on media containing lead cation. Sacchannyces cerevisiae 220 cultured was put into the media cotaining lead cation and it's biosorp-tion to lead cation was studied. The results show this strain has maximum biosorption ratio (96.6%) to 6mg/L lead cation, biosorption-equilibrilium period is 25-30min, biosorption kinitics equation is q-26.318C/ (1 + 0.437C) . Acetic acid is benefit to de-biosorption, glucose and KH2PO4 can improve biosorption ratio to lead cation.
