Objective To investigate the influencing factors of the controlled virtual touch tissue quantification (VTQ) in liver of patients with type 2 diabetes mellitus (T2DM) complicated withnon-alcoholic fatty liver disease (NAFLD). Methods Two hundred and twenty-seven patients with T2DM complicated with NAFLD were enrolled in this study,and the shear wave speed of the liver was measured by VTQ. Levels of the fasting plasma glucose, glycated hemoglobin,total cholesterol three acids glyceride, low density lipoprotein, high density lipoprotein , aspertate aminotransferase , alanine aminotransferase , gamma glutamyl transpeptidase and uric acid were measured. The relationships among VTQ and the severity of NAFLD , and those quantitative indexes were analyzed. Results Univariate analysis showed that the value of shear wave speed was negatively correlated with age,duration of diabetes,INS and HDL-C,while was positively correlated with HbA1c and AST. Conclusion Age, sex and levels of serum HbA1c,INS,AST and HLD-C might affect the values of shear wave speed in patients with T2DM complicated with NAFLD.

Objective To observe the anatomical constant sign of the parapharyngeal space operation via endoscopy-assisted transoral approach,and provide evidence for the treatment of the lesions of the pharyngeal space and improve the success rate of the operation. Methods CT multi plane reconstruction and three dimensional reconstruction were performed on 10 fresh dead bodies who were acquired from January 2015 to September 2015,the structure of the lateral pharyngeal space was observed,and the parapharyngeal space operation was performed via endoscopy-assisted transoral approach.Results The CT images showed that dispharynx of very low density extended posterior-lateral into the pharyngeal recess,lateral pharyngeal space located in the lateral pharyngeal recess,a low density triangular shadow with a nar-row of the front and width in the back,wing within muscles,wing outside muscles,masseter and temporal muscle located in the lateral pharyn-geal side clearance,which showed a medium density shadow,styloid process located in the front shadow of pharynx side clearance,the back of the internal carotid artery of pharynx side clearance,which showed medium density shadow.The blood vessels in the pharyngeal space and the nerve development was not clear.Stem styloid located in the temporal bone of the skull base drum subordinates,with length of (24.98 ± 2.01)mm,the internal structures of parapharyngeal space located in styloid process and around the surface of the deep muscular,the outside of styloid process had external carotid artery,facial nerve and mastoid.Inside of the base of styloid process had jugular vein foramen and hypo-glossal canal outside hole,the front inner side had carotid canal outside hole,the foramen spinosum,and oval foramen,the rear with stem hole.The distance between left and right side of root of styloid process to adjacent structures was compared,and the difference had no statisti-cal significance(P >0.05).In addition to the root of the styloid process to stylomastoid foramen.The difference of root of styloid process of males to adjacent structure was greater than that of the females,the difference had statistical significance(P <0.05).Conclusion Endo-scopic-assisted transoral approach to the parapharyngeal space operation hasthe styloid process as the marks of anatomy,the distance of styloid process to adjacent anatomical structures is as the reference,which helps to find and identify the parapharyngeal space of peripheral nerve, blood vessel,etc.

Objective To study the therapeutic effect of continuous renal replacement therapy (CRRT) in renal failure after liver transplantation.Methods Renal function in 82 patients who underwent CRRT in the perioperative period of liver transplantation were retrospectively analyzed.Results There were significant differences in ALT,TB,BUN and Cr before and after the treatment (P ＜ 0.05).The differences were significant in glutamic-pyruvic transaminase (ALT),creatinine phosphate kinase (CPK) and C reactive protein (CPR) before and after the treatment (P ＜0.05).There were significant improvements in K+,Na+,Cl-,HCO3-and CVP before and after the treatment (P ＜ 0.05),while the differences were not significant in other biochemical parameters (P ＞ 0.05).This research also looked at the effect of timing of CRRT on renal function recovery.Based on the RIFLE classification of AKI,the ratio of renal function recovery in RIFLE-Ⅰ was significantly higher than RIFLE-F (P ＜ 0.05).Conclusion CRRT treatment significantly improved the prognosis of patients with acute renal failure after liver transplantation.

Objective The purpose of this study was to investigate the preparation of a pulmonary self-expanding valved stent and the percutaneous implantation of a valved stent in the pulmonary valve position without cardiopulmonary bypass.Methods A bovine jugular valve conduit was trimmed to remove the extraneous materials to reduce profile,and then was sutured onto nitinol stents to form a pulmonary self-expanding valved stent.In vitro,it was tested by a pulsatile mock loop system.Through a 24F delivery system,the valved stents were deployed in the pulmonary valve position of 8 pigs,and then in vivo assessment with echocardiography and a postmortem examination were carried out.Results The pulmonary self-expanding valved stent has an inner diameter of (21.9 ± 1.6) mm,an outer diameter of (24.6 ± 1.5 ) mm,a length of (27.9 ± 4.3 )mm,and an effective orifice area of ( 1.8 ±0.2) cm2.7 of the 8 valved stents were exactly deployed in the native pulmonary valve position,1 valved stent failed.The transvalvular pressure gradient was (7.9 ± 3.3 ) mm Hg by catheter measurement,(9.3 ±4.1 ) mm Hg by Doppler echocardiography.The angiography showed no migration,no regurgitation and no paravalvular leak.The echocartiography showed all the new valves opened and closed well with 2 cases of mild regurgitation.Postmortem examination confirmed the valved stent straddled the pulmonary annuli without migration,the native valve was locked between the stent and arterial wall.Conclusion The acute study demonstrates that the self-expanding valved stent can be successfully implanted in the pulmonary position by a catheter delivery system and function well.Percutaneous pulmonary valve implantation without cardiopulmonary bypass is feasible and has a wide clinical perspective.

BACKGROUND AND OBJECTIVETransient receptor potential canonical (TRPC) proteins, a group of Ca2' permeable nonselective cation channels, are thought to constitute store-operated calcium channels (SOCC) and mediate store-operated calcium entry (SOCE) in various cell types. Members of TRPC have been found to be involved in abnormal proliferation, differentiation, and growth of cancer cells. The aim of this study is to detect the mRNA and protein expression of TRPC in non-small cell lung cancer (NSCLC).

METHODSReal-time quantitative PCRwas performed to screen the expression of TRPC mRNA in NSCLC tissue. Protein expression of TRPC was detected by Western blot.

RESULTSAmong the seven family members of TRPC so far identified (TRPC1-7), we detected the expression ofTRPC1, TRPC3, TRPC4, TRPC6 mRNA in 24 cases of NSCLC tissue; TRPC2, TRPC5 and TRPC7 mRNA were not detectable. The relative abundance of the expressed TRPC was TRPC1 approximately equal TRPC6 > TRPC3 > TRPC4. Western blot confirmed the protein expression of TRPC1, TRPC3, TRPC4 and TRPC6 in NSCLC tissue.

CONCLUSIONOut of the seven members of TRPC, we found TRPC1, TRPC3, TRPC4, TRPC6 mRNA and protein were selectively expressed in human NSCLC tissue. This study could provide a basis for future exploration of the individual role of these TRPC proteins in mediating SOCE and in the progression of lung cancer.

As an effective anticancer drug, the clinical limitation of doxorubicin (Dox) is the time- and dose-dependent cardiotoxicity. Yes-associated protein 1 (YAP1) interacts with transcription factor TEA domain 1 (TEAD1) and plays an important role in cell proliferation and survival. However, the role of YAP1 in Dox-induced cardiomyopathy has not been reported. In this study, the expression of YAP1 was reduced in clinical human failing hearts with dilated cardiomyopathy and Dox-induced

OBJECTIVETo investigate the epidemiology characteristics of norovirus among diarrheal outpatients in China.

METHODSDiarrhea cases were monitored at emergency/outpatient departments at 173 hospitals in 27 provinces of China, with clinical and epidemiological data, and fecal specimens collected and sent to 58 network-laboratories to detect norovirus by RT-PCR method, and to analyze the positive rate of norovirus in various regions, population and time during 2009-2013.

RESULTS11.6% of the 34 031 diarrheal cases under surveillance were found with norovirus. Age group of 6-23 month-old children and that of people over 45 years old were found with the highest positive percentage, 13.7% and 12.4% respectively. Positive percentage of norovirus peaks in autumn and winter in a year; it peaks in mid-temperate zones (10.7%) and warm-temperate zones (11.6%) in winter. It peaks in sub-tropical zones in autumn (14.3%). The most prevalent genogroups detected were norovirus G II, accounting for 89.9% of identified strains.

CONCLUSIONNorovirus affects all ages and was most prevalent in children and the elderly among diarrhea outpatients. Norovirus' positive percentage showed strong seasonal pattern, and peaks at different times of a year in different climate zones of China. Since no effective preventive measures existed, further study on norovirus epidemiology and intervention strategies should be conducted in future.
