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.

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.

Background and objective Both of lung cancer incidence and mortality rank first among all cancers in China.Previous lung cancer screening trials were mostly selective screening for high-risk groups such as smokers.Non-smoking women accounted for a considerable proportion of lung cancer cases in Asia.This study aimed to evaluate the outcome of community-based mass screening in Guangzhou and identify the high-risk factors for lung cancer.Methods Residents aged 40-74 years in Guangzhou were screened with low-dose computed tomography(LDCT)for lung cancer and the pulmonary nodules were classified and managed according to China National Lung Cancer Screening Guideline with Low-dose Computed Tomography(2018 version).The detection rate of positive nodules was calculated.Before the LDCT examination,residents were required to complete a"lung cancer risk factors questionnaire".The risk factors of the questionnaire were analyzed by least absolute shrinkage and selection operator(LASSO)penalized Logistic regression analysis.Results A total of 6256 residents were included in this study.1228 positive nodules(19.63％)and 117 lung cancers were confirmed,including 6 cases of Tis,103 cases of stage Ⅰ(accounting for 88.03％of lung cancer).The results of LASSO penalized Logistic regression analysis indicated that age ≥50 yr(OR=1.07,95％CI:1.06-1.07),history of cancer(OR=3.29,95％CI:3.22-3.37),textile industry(OR=1.10,95％CI:1.08-1.13),use coal for cooking in childhood(OR=1.14,95％CI:1.13-1.16)and food al-lergy(OR=1.10,95％CI:1.07-1.13)were risk factors of lung cancer for female in this district.Conclusion This study highlighted that numerous early stages of lung cancer cases were detected by LDCT,which could be applied to screen-ing of lung cancer in women.Besides,age ≥50 yr,personal history of cancer,textile industry and use coal for cooking in childhood are risk factors for women in this district,which suggested that it's high time to raise the awareness of early lung cancer screening in this group.

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
