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.

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

objective To evaluate endoscopic surgery for high risk patients over 70 years old with severe acute cholangitis. Methods From October 1991 to October 2003, 84 high risk patients over 70 years old suffering from severe acute cholangitis were included and divided into laparotomy surgery (ST) and endoscopic surgery (ET) group. Results 80 patients were cured. The care rate was 81.2% in ST group and 91.6% in ET group. The mortality rate was lower in ET compared with ST (9.1% vs 18.8%). The rate of complication was reduced from 37.5% in ST group to 13.9% in ET group. The average duration of drainage was reduced from 49.4 days in ST group to 18.6 days in ET group. The total treatment days were shortened from 46.2 days to 22.8 days comparing ST with ET. Conclusions Endoscopic surgery should be the first choice for the senile and high risk patients with severe acute cholangitis. Endoscopic surgery was convenient, with mininal injury, safe and effective, and period of treatment was shortened, especially for elderly or critically ill patients, as well as those with MODS or previous billiary operations.

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.

Objective To investigate the long-term effects of low dosage Changle intake on the serum insulin and hepatocyte glycogen of rats. Methods The levels of serum insulin and hepatocyte glycogen in rat were measured by radioimmunoassay and microscopy image analysis system after 6 and 7 months of administrated with Changle(0. 1, 0.2, 2.0 and 10.0 mg/kg). Results Taken Changle for 6 months, the serum insulin level in the 10.0 mg/kg group reduced, hepatocyte glycogen level increased in the female and the male rats. In 0.1, 0.2, and 2.0 mg/kg groups, the serum insulin level increased and the hepatocyte glycogen level decreased in the male. After 6 months of the Changle treatment, the treatment was then followed by normal food, one month later, the level of serum insulin and hepatocyte glycogen returned to the normal level. Conclusion A long-term low dosage exposure of Changle can induce the serum insulin and hepatocyte glycogen changes in rats and the serum insulin and hepatocyte glycogen levels may return to the normal levels after a short time of stopping Changle intake.

Objective:To investigate the duck thymocyte surface antigens.Methods:Repeated immunization of normal BALB/c mice with separated thymocyte from mature duck result in the production of mAbs which react with duck thymocyte surface antigens.Applying the immunohistochemistry assay,tracing the originating and distributing of lymphocytes which reacted with mAb in spleen,thymus,and bursa of duck different development stages.Results:Five monoclonal antibody-producing hybridomas(B6,B8,C12,E6,H5)were isolated.According to the result of immunohistochemistry assay,there were distributing strained lymphocytes in thymus,bursa and spleen of duck.The stained cells belonged to different populations.Conclusion:The mAb C12 reacted with the common cell surface marker of between mature T lymphocytes and dendritic cells.

Objective To explore the protective effect of resveratrol on rat brain injury resulting from severe acute pancreatitis (SAP). Methods Ninety-six male Sprague-Dawley rats were randomly divided into four groups:sham-operation (SO) group,severe acute pancreatitis (SAP) group,resveratrol-treated (RES) group and dexamethasone-treated (DEX) group,with eight rats in each group evaluated at 3,6 and 12 h. Levels of serum myelin basic protein (MBP),tight junction protein zonula occludens 1 (Zo-1),TNF-? and IL-6 were determined by ELISA. The ultrastructural changes of the brain and pancreatic tissues were examined using a transmission electron microscope. Results MBP,Zo-1,TNF-? and IL-6 levels in RES group were lower than those in SAP group at all time points (P0.05). Conclusion The degradation of Zo-1 is involved in the pathophysiology of brain injury in SAP; MBP can be used as a marker of brain injury in SAP rats. Resveratrol can inhibit brain injury associated with SAP.
