Objective To evaluate the effects of high-fidelity simulation teaching on the clinical decision-making ability and critical thinking ability of new nurses. Methods A total of 39 newly recruited nurses in our hospital in 2014 were included in this study, and high-fidelity simulation teaching was used in pre-job training. They were investigated by the clinical decision-making ability measuring tool and critical thinking disposition inventory-Chinese version before and after the training. Results Before the high-fidelity simulation teaching, the scores of the new nurses′ clinical decision-making ability and critical thinking ability were (81. 50 ± 6. 87) and (309. 90 ± 28. 15). After the high-fidelity simulation teaching, the scores increased to (92. 91 ± 6. 35) and (318. 13 ± 26. 24). The differences before and after the training were statistically significant (t=10. 19, 2. 83;P<0. 01). Conclusions The high-fidelity simulation teaching in pre-job training can improve the clinical decision-making ability and critical thinking ability of new nurses.

Objective To observe the clinical effects of arthroscopic reconstruction for anterior cruciate ligament ( ACL ) tear using tension-relieving technique and enhanced recovery after surgery ( ERAS ) . Methods Between May 2014 and June 2016, 80 patients with ACL tear were randomly di-vided into 2 equal groups. The experimental group was treated with arthroscopic reconstruction using hamstring tendon autograft and tension-relieving technique followed by ERAS; the control group was treated with arthroscopic reconstruction using hamstring tendon autograft only followed by conventional postoperative re-covery. The 2 groups were compared in terms of knee flexion angles at postoperative 2nd, 4th and 8th weeks, and the IKDC ( International Knee Documentation Committee ) , HSS ( Hospital for Special Surgery ) , and Lysholm scores at postoperative 3rd, 6th and 12th months. Results The 80 patients obtained an average follow-up of 12. 3 ± 1. 7 months. Arthroscopy one year postoperation revealed fine ACL growth without laxity or other complications in the experimental group. Joint stiffness appeared in one case at 2 months postoperation and ACL laxity was observed in 3 cases by arthroscopy at 12 months postoperation in the control group. The knee flexion angles at postoperative 2nd, 4th and 8th weeks, and the IKDC, HSS and Lysholm scores at postoperative 3rd, 6th and 12th months in the experimental group were significantly better than those in the control group ( P <0. 05 ) . In both groups, the IKDC, HSS and Lysholm scores at postoperative 3rd, 6th and 12th months and the knee flexion angles at postoperative 2nd, 4th and 8th weeks were all significantly im-proved than the preoperative values ( P <0. 05 ) . Conclusion In arthroscopic reconstruction for ACL tear, tension-relieving technique combined with ERAS can promote functional recovery of the knee and reduce postoperative complications, facilitating early recovery of sports function.

Depression is a common emotional disease，causing a heavy burden of disease on patients' families and society.Its pathogenesis is not yet fully understood，andmay be related to inflammation，neurotransmitters，neurotrophicfactors，hippocampal neuronal synaptic plasticity，oxidative stress，etc.Clinical application of Western medicine to treat depression has serious side effects，poor patient compliance，the effective rate is not high，rebound after withdrawal，etc.Traditional Chinese medicine treatment of depression has the characteristics of low side effects and high patient compliance. Depression belongs to the category of depression syndromein traditional Chinese medicine.Traditional Chinese medicine believes that the main symptoms of depression include depressed liver Qi，stagnated Qi transforming into fire，deficiency in heart and spleen，deficiency in heart and lung，stagnation of phlegm and Qi，deficiency of liver and kidney，etc. Banxia Houpu Tang is a classic recipe contained in"Synopsis of the Golden Chamber" by Zhang Zhongjing in the Han Dynasty， it has the effect of treating depression syndrome of stagnation of phlegm and Qi.By searching the literatures of Banxia Houpu Tang in the treatment of depression in Chinese knowledge network database （CNKI），Chinese biomedical literature database （CBM）， Wanfang Data， Pubmed， Embase， Web of Science and other databases，we found that both clinical application and experimental research suggest that Banxia Houpu Tang has a significant antidepressant effect. Clinical studies have shown that Banxia Houpu Tang can improve the scores of anxiety scales and depression scales of patients with depression. The antidepressant effect is significant， and the advantages are prominent. Experimental research shows that the antidepressant effect of Banxia Houpu Tang and its effective components may be related to the factors such as intervention of inflammatory response， influence of neurotransmitters， regulation of neurotrophic factors， improvement of synaptic plasticity of hippocampal neurons and reduce oxidative stress，etc. Therefore，this paper reviews several types of depression in the clinical treatment of Banxia Houpu Tang and the related experimental studies of Banxia Houpu Tang.

OBJECTIVETo investigate the protein expression profiles of the major food-borne pathogen Campylobacter jejuni NCTC11168.

METHODSMembrane and soluble cellular proteins were extracted from the genome-sequenced C. jejuni strain NCTC11168. Protein expression profiles were determined using two-dimensional gel electrophoresis (2-DE). All the detected spots on the 2-DE map were subjected to matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/TOF) analysis.

RESULTSA total of 537 and 333 spots were detected from the whole cell and membrane-associated proteins of C. jejuni NCTC11168 cultured on Columbia agar medium at 42 °C by 2-DE and Coomassie Brilliant Blue staining, respectively. Analyses of whole cell and membrane-associated proteins included 399 and 133 spots, respectively, which included 182 and 53 functional proteins identified by MALDI-TOF/TOF analysis.

CONCLUSIONThe comprehensive expression protein profiles of C. jeuni NCTC11168 obtained in this study will be useful for elucidating the roles of these proteins in further pathogenesis investigation.

Data mining is an important method to obtain the key information from a large amount of data, and it is widely applied in the research on the modernization of traditional Chinese medicine(TCM). The compatibility law of herbs is a key issue in the research of TCM prescriptions. This reflects the flexibility and effectiveness of TCM prescriptions, and it is also a crucial link to the development of TCM modernization. Therefore, it is the core purpose of the research on TCM prescriptions to find the compatibility law of herbs and clarify the scientific connotation. Data mining, as an effective method and an important approach, has formed a standardized system in the research of compatibility law of herbs, which can reveal the relationship between different Chinese herbs and summarize the internal rules in compatibility. Two hundred and twenty two effective papers were sorted out and categorized in this article. The results showed that data mining was mainly applied in finding the core Chinese herb pairs, summarizing the utility and attributes of TCM prescriptions, revealing the relationship between prescriptions, Chinese herbs and syndromes, finding the optimal dose of Chinese herbs, and producing the new prescriptions. The problems of data mining in research of herbs compatibility rules were summarized, and its development and trend in current researches were discussed in this article to provide useful references for the in-depth study of data mining in the compatibility law of Chinese herbs.

Objective:To observe the clinical efficacy of modified Erchentang on CXC chemokine ligand receptors (CXCR1/2)and their ligands CXCL8,macrophage inflammatory protein -2(MIP-2) in patients of chronic obstructive pulmonary disease(AECOPD)at acute exacerbation stage,and assess the effect and mechanism of modified Erchentang on anti-inflammatory in patients of AECOPD. Method:This study was a multicenter, randomized single blind, controlled trial. The authors selected 200 cases in conformity to the standards of AECOPD. The AECOPD patients were randomly divided into modified Erchentang group and control group. In addition to the western medicine, modified Erchentang was also given to the modified Erchentang group, and Jizhitangjiang was given to the control group for 14 days. Each group was observed for the alleviation of the symptoms. Euzyme-linked immunosorbent assay (ELISA) was used to determine the levels of CXCL8 and MIP-2 in the patients' plasma of all groups before and after treatment. Western blot were used to detect the levels of CXCR1, CXCR2 and CXCL8 protein in peripheral blood mononuclear cells(PBMCs). Immunocytochemistry (ICC) method was used to detect the expressions of CXCL8, CXCR1 and CXCR2 protein in PBMCs. Result:The level of CXCL8 in plasma, and the expressions of CXCR1, CXCR2 and CXCL8 mRNA and protein in the modified Erchentang group were decreased significantly than those in the control group(P<0.05,P<0.01). Conclusion:Modified Erchentang has an anti-inflammatory effect on AECOPD. Its mechanism may be related to the down-regulation of the expressions of CXCL8, CXCR1 and CXCR2, the reduction of synthesis and release of CXCL8 and MIP-2, the inhibition of the chemotaxis and activity of inflammatory cells, and the prevention of inflammation progress.
