Objective: To explore the clinical and magnetic resonance imaging (MRI) features of papillary musclehypertrophic cardiomyopathy. Methods: Our research contained 2 groups: Papillary muscle hypertrophic cardiomyopathy group,n=21 patients treated in our hospital from 2013-01 to 2015-12 including 18 male and 3 female; Control group,n=50 subjects without cardiovascular disease those were conifrmed by our hospital at the same period of time. Clinical and MRI examinations were conducted in all patients, the ifndings were compared between 2 groups. Results: Compared with control subjects, papillary musclehypertrophic cardiomyopathy patients had the main symptoms of shortness of breath, chest tightness and pain; associated with systolic murmur; ECG could be normal or with T wave inversion; cardiac MRI showed that 1/2 papillary muscle diameter>1.1cm. Blood levels of triglyceride, left atrial diameter, inter-ventricular septum thickness, the values of E/A and EDT were statistically different between 2 groups, allP<0.05. Conclusion: Clinical features of papillary muscle hypertrophic cardiomyopathy were lack of speciifcity, the morbidity and clinical signiifcance should be further investigated.

In 1982, ADP-ribosylation factors (ARFs), a family of GTP-binding proteins associated with Golgi complexes, were initially recognized based on their ability to stimulate the ADP-ribosyltransferase activity of cholera toxin in vitro, and named so. In fact, this pathophysiologic activity has been useful for functionally defining members of the ARF family. However, during last decade, genetic and biochemical studies have shown the physiologic role of ARFs that also play an essential role in intracellular vesicular transport, particularly in Golgi complexes, activate phospholipase D activity as a nod of signal transduction of cells. Moreover, their more functions were revealed continuously recently. Especially, human ARF1 was found earliest, and studied profoundly in human body cell. Therefore, in this article, there is a comprehensive review about its regulators and effectors, functions and its possibilities involved in tumorigenesis, development of tumors.

Objective To study the correlation between organizational commitment of nurses and their intention to drop out. Methods Toally 304 contract nurses were recruited in this investigation. The questionnaires including demographic data, scale of organizational commitment and intention to drop out scale were used. Results The score of intention to drop out was 16.94 ± 2.16. The score on organizational commitment was 71.19 ± 6.65. There was a positive correlation between intention to drop out and organizational commitment among the contract nurses. Conclusions Improving contract nurses′organizational commitment can be an effective mean to reduce contract nurses′intention to drop out. It is an important means to promote the development of the nurse team and provide a reference for the scientific development of nursing.

Objective To establish a stable brain injury model with pancreatitis and explore the mechanism of brain injury resulting from severe acute pancreatitis (SAP) in experimental rat models. Methods Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham operation (SO) group, SAP group and trypsin group, with eight rats in each. Brain tissue and pancreas tissue specimens were collected at 12 h after treatment. Death rate in each group was evaluated; the level of tight junction protein zonula occludens 1 (Zo-1) was determined by enzyme-linked immunosorbent assay. The ultrastructure of the brain tissues was examined using transmission electronic microscope; pathological changes in the brain tissues were observed with HE staining. Results The death rate was increased significantly in SAP group compared with that in trypsin group; no rats in SO group died. Zo-1 level was obviously lower in SO group than in SAP group and trypsin group (P<0.05). The ultrastructural changes were seen in the latter two groups, including obvious neuronal cell swelling, capiliary stasis, increased vascular permeability, thrombosis and cell apoptosis. Conclusion Trypsin may cause brain injury with pancratitis. The death rate of SAP model established by trypsin was low. We have provided a stable animal brain injury model for further study and treatment of brain injury.

The application and development of catalytic fluorimetry in recent years were reviewed with 103 references. The new technique and application of catalytic fluorimetric methods, such as the determination of catalyst and activator, multicomponent determination, enzyme catalysis, the effect of micelle in multicomponent determination and enzyme catalysis, the combination with flow-injection or stopped-flow tachniques and laser induced fluorimetry, time resolved fluorimetry, bioreactor control, biosensor, medicine assay, bioanalysis were mainly discussed. Future study was envisioned

Prevention of infection by the human papillomavirus (HPV) has become a hot research topic since the relationship between the HPV and cervical cancer was confirmed. Persistent infection with HPV and early expression of proteins has an important role in the pathogenesis of cervical cancer. Vaccines that protect against four high-risk types of HPV (-6, -11, -16, -18) have been used worldwide. A bivalent vaccine (HPV-16 and -18) developed by Walvax is in clinical trials. This study reviews progress in ascertainment of the structure and function of the HPV genome, the molecular mechanism of carcinogenesis, and vaccines based on virus-like particles.

The present situation and the deficiencies of high-value medical consumables were analyzed. Two-dimensional barcode technology was suggested to be involved in the whole-course dynamic tracing of the high-value consumables to combine the high-value consumables information with the patient information. The course included the links of acquisi-tion, warehousing, barcode preparation, delivering and charging. Two-dimensional barcode technology may enhance the medical consumables management and decrease medical dispute, and thus contributes to the development of digital hospi-tal.

Objective To evaluate the the brow position and shape in young Chinese women using a photography measurement.Methods A total of 100 Chinese women aged 20 to 30 years were photographed to determine the distance between brow and eye.Measurements were made from a horizontal plane through the lateral canthus of right eye to three vertical points on the upper brow margin at the medial canthus,lateral limbus of the iris,and lateral canthus.Results The distance between brow and eye in young Chinese women was 2.12,2.52 and 2.46 cm at medial canthus,lateral limbus of the iris and lateral canthus,respectively.The distances were higher between the brows and eyes at lateral limbus of the iris and lateral canthus than that at medial canthus (P＜0.05).Conclusions The measurement used in this study is a simple and practical quantitative method.The results can be used to guide the surgical choice and help to evaluate the surgical techniques.
