Before and after the second class activities, the caring ability inventory scale and self scale-rating for self-directed learning (SRSSDL) were used to assess 34 students. Result After the activities, students' caring ability and self-directed learning ability were statistically significantly improved (P<0.01). Conclusion The extracurricular activities based onspecialist nursing cliniccan stimulate the learning interest of nursing students and improve their self-directed learning ability and humanistic care ability.

To explore the relationship between blood level of big endothelin and contrast-induced acute kidney injury (CI-AKI) in patients with emergent percutaneous coronary intervention (PCI). Methods: A total of 1061 consecutive patients received emergent PCI in our hospital from 2013-01 to 2015-06 were enrolled. According to blood levels of big endothelin, the patients were divided into 2 groups: Normal big endothelin group, n=236 and Elevated big endothelin group, n=825. The baseline condition, procedural features, occurrence rate of CI-AKI and composite endpoint events at 6 and 12 months post-operation were studied which including nonfatal myocardial infarction, revascularization, stroke and all-cause death. The risk factors for CI-AKI occurrence were identified by Logistic analysis. Results: The overall occurrence rate of CI-AKI was 22.7% (241/1061). Compared with Normal big endothelin group, Elevated big endothelin group had the higher incidence of CI-AKI, increased composite endpoint events at 6 and 12 months post-operation with P=0.041, P=0.040 and P=0.021, respectively. With adjusted covariates, elevated blood level of big endothelin, no matter as a continuous variable or categorical variable had the enhanced risk of CI-AKI incidence in patients after emergent PCI. Conclusion: Elevated blood level of big endothelin may significantly increase the risk of CI-AKI in patients with emergent PCI.

Objective To investigate the ameliorative effect of sulforaphane on inflammatory response and airway remodeling in rats with chronic obstructive pulmonary disease(COPD).Methods Seventy-five SD rats were randomly divided into the normal group,the model group,and the low-,medium-,and high-dose groups of sulforaphane,with 15 rats in each group.Except for the normal group,the COPD model was prepared in the remaining group using aroma smoke inhalation combined with intratracheal droplet lipopolysaccharide(LPS)method.After the successful modelling,the rats were administered the drug by gavage for 28 days.At the end of the administration,the general conditions of the rats in each group were observed,and the lung function[forced vital capacity(FVC),peak expiratory flow-rate(PEF),forceful expiratory volume in 1 second(FEV1)]was examined,and the pathological changes of the lung tissues were observed by hematoxylin-eosin(HE)staining method,and the indexes of airway remodeling(thickness of the bronchial wall,thickness of the smooth muscle)were measured;the enzyme-linked immunosorbent assay(ELISA)was used to examine the lung function of the rats.The levels of inflammatory factors[tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β)]were detected in lung tissue by enzyme-linked immunosorbent assay(ELISA),and changes in the protein expressions of Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MyD88),and nuclear transcription factor κB(NF-κB)were detected in lung tissue by Western Blot.Results(1)The rats in the model group had dry and lack of glossy fur,obvious coughing and nose scratching,shortness of breath,slow movement,and preferred to arch their backs and lie curled up;the rats in the low-,medium-and high-dose groups of sulforaphane showed significant improvement in shortness of breath,coughing,and other abnormal manifestations.(2)HE staining showed that the airway wall and smooth muscle of rats in the model group were thickened,the airway epithelium was damaged,and alveolar destruction,fusion,and massive infiltration of inflammatory cells were seen;the histopathological changes in the lungs of rats in the low-,medium-and high-dose groups of sulforaphane improved to varying degrees,with the airway wall becoming thinner,the degree of alveolar destruction being reduced,and the infiltration of inflammatory cells being reduced.(3)Compared with the normal group,FVC,PEF and FEV1 were significantly reduced in the model group(P＜0.05),and the levels of TNF-α and IL-1β,bronchial wall thickness,smooth muscle thickness,and the expression levels of TLR4,MyD88 and NF-κB were significantly increased in the model group(P＜0.05);and in comparison with the model group,the levels of FVC,PEF,and FEV1 were significantly increased in the rats in the sulforaphane low-,medium-,and high-dose groups(P＜0.05),and the levels of TNF-α,IL-1β,bronchial wall thickness,smooth muscle thickness,and the expression levels of TLR4,MyD88,and NF-κB were significantly decreased(P＜0.05)compared with the model group.Conclusion Sulforaphane helps to inhibit the inflammatory response,attenuate airway remodeling,and improve the pathological injury and lung function of lung tissue in rats with COPD,and its mechanism may be related to the inhibition of TLR4,MyD88,and NF-κB protein expressions.

OBJECTIVETo study the principle and surgical managements for the patients with anatomic variants of hepatic artery in the procedure of pancreaticoduodenectomy (PD).

METHODSOne hundred and seventy-six patients who underwent PD between January 2000 and July 2007 were investigated retrospectively. Hepatic arterial variants were analyzed according to the intraoperative finding and CT imaging were reviewed postoperatively.

RESULTSHepatic arterial variants were found intraoperatively in 20 cases of all 176 patients. Accessory right heptic artery, replaced right heptic artery and common heptic artery arising from the superior mesenteric artery (SMA) were present in 9 (5.1%), 5 (2.8%), 4 (2.3%) cases respectively,and replaced right heptic artery coming from the gastroduodenal artery was present in 2 cases (2.9%). All the variants of hepatic arteries arising from the superior mesenteric artery could be observed in spiral CT imaging. Most of the variant arteries were dissected intact intraoperatively except 2 cases with accessory right heptic artery arising from SMA.

CONCLUSIONSPerforming CT scan preoperatively, especially CTA,is effective to diagnose these disorders. Skillful surgical techniques can manage the anatomic variants safely.
