This paper made an intensive study on existing problems of the current public hospital cost accounting system and proposed amendments by sorting out cost accounting′s content and related concepts.The application value of this paper is,on one hand,to provide a reference for the formulation of cost and expense standards in government accounting standards,and on the other hand,to better its cost accounting method,and to lay system foundation for increasing accuracy efficiency and timeliness of cost accounting.And corresponding proposals were offered to make public hospitals′cost accounting results better applied in hospital management,government pricing and social insurance payment.

Objective: To explore influence of dragon dancing sport on cardiac function and its mechanism. Methods: A total of 20 male students learning in physical education department of Physical Education College of Jishou University were enrolled, randomly and equally divided into dragon dancing sport group (dragon dancing group, received dragon dancing training) and control group (performed daily activity). Indexes of cardiac function were measured by color-code Doppler echocardiography before and 16 weeks after training. Results: Compared with control group after 16-week training, there was significant decrease in heart rate [(66.00±3.39) times/min vs. (60.50±6.02) times/min], significant increase in left ventricular early diastolic peak filling velocity（E）[(82.4±10.17)cm/s vs. (93.01±10.89)cm/s], rate of E/ A（left ventricular late diastolic peak filling velocity）[(1.89±0.24) vs. (2.29±0.47)], stroke volume [(65.5±10.61)ml vs. (75.59±13.35)ml], stroke index [(36.19±6.15)ml/m2 vs. (40.43±8.35) ml/m2], cardiac index [(2.39±0.47)L•min-1•m-2 vs. (2.46±0.65) L•min-1•m-2] in dragon dancing group, P<0.05 all. Conclusion: Dragon dancing sport can significantly improve cardiac function.

Inflammatory bowel disease (IBD) could lead to the complexity of intra-abdominal pathology and patients' malnutrition,which might greatly increase the risk of operation.Laparoscopic minimally invasive surgery is playing an important role in the treatment of IBD,with the advantages of faster postoperative recovery,shorter duration of hospital stay and lower incidence of postoperative complications.And some new techniques for IBD have been reported in the western countries,such as single-incision laparoscopic surgery,natural orifice transluminal endoscopic surgery,robot-assisted laparoscopic surgery and so on.However,the new techniques are not widely used in China,and it is necessary to carry out a series of clinical practices,which should be carefully selected for IBD patients undergoing minimally invasive surgery.

At present,the technology to predict the response to neoadjuvant therapy with biomakers has been widely used in clinical practice.The approaches of biomarkers detection are various,including immunohistochemistry,detection of serum biomarkers conventional blood tests,gene expression profile analysis,single nucleotide polymorphisms,miRNAs,proteomics analysis.With the development of biotechnology,the technology of biomarkers detection is expected to become effective means in assessment of adjuvant therapy,risk,prognosis and individualization in esophageal cancer treatment.

Objective:To study the torsional property and rotary fatigue fracture of Smart K files and R reamers made of nickel-titanium alloy. Methods:The torsional property and rotary fatigue fracture behavior of Smart K files and R reamers were evaluated by means of specially-designed torsional device and simulated endodontic root canals system. The instrument surface and the rotary fatigue fractured surface were investigated by optical microscope and scanning electron microscope. Results:Compared with ANSI/ADA specification No.28, maximum torque values of Smart K and R endodontic instrument were higher. Tensile stresses on the outer surface of the endodontic instruments played a dominant role in fracture initiation during rotary fatigue fracture. The rotary numbers corresponding to rotary fatigue fracture decreased with the increase of the instrument size and curvature. Smart K and R endodontic instruments exhibited good ductility. Dimples were found on the fractured surface, and the fatigue fracture was the typical ductile fracture. Conclusion:Smartendodontic instruments have excellent torsional and rotary fatigue fracture resistance properties.

Objective:To investigate the expression of Hpa and its correlation with the microvessel density(MVD) in oral squamous-cell carcinoma(OSCC), thereby learning the function of Hpa in the tumor angiogenesis,invasion and lymph node metastasis.Methods:The expression of Hpa was studied in 48 patients with OSCCs, 15 patients with leukoplakia and 10 normal person with healthy oral mucosa by conventional immunohistochemistry and in situ hybridization. MVD was assessed with anti-CD31 antibody. Results: Positive expression ratios of Hpa and Hpa mRNA in leukoplakia were significantly higher than those in normal oral mucosa, while were significantly lower than in OSCC(P

Objective To clone acidic mammalian chitinase (AMCase) gene and analyze the sequences of the nucleotides and encoded amino acids. Methods Total RNA was isolated from the stomach of BALB/c mouse and the mRNA was reversely transcribed into cDNA. AMCase gene was amplified by polymerase chain reaction and inserted into recombinant clone vector of pMD18-T. Sequence alignment was performed with DNAMAN 4.0 software. Isoelectric point, amino acid composition, signal peptide and transmembrane helices were analyzed with SignalP 3.0 Server and TMHMM Server v.2.0. Results The cloned gene encodes a protein of 473 amino acids with molecular weight of 51.93 kDa and isoelectric point 4.73. Extensive amino acid sequence homology (up to 99.57%) was found when compared with AMCase. Both protein encoded by this cloned gene and AMCase belonged to family 18 chitinase, which was composed of signal peptide (amino acid position 1-21), the catalytic domain (amino acid position 22-391), hinge region (amino acid position 392-425) and chitin binding domain (amino acid position 426-473). There were two mutations of amino acid in the catalytic domain and hinge region with this AMCase mutant. The amino acid of Ala(position 292)was mutated into amino acid of Pro, and the amino acid of Thr(position 404)was mutated into amino acid of Ser. Conclusion This sequence is a mutant of AMCase gene. Identification of the biological characteristics will play important role in the further study of its biological function by molecular biology technique.
