Objective To figure out the preliminary clinical value of real-time three-dimensional echocardiography(RT-3DE) in evaluating the systolic dyssynchrony in patients with coronary artery heart disease(CAD).Methods Eighty patients who were suspected as CAD were included in this study.RT-3DE was performed first.After the analysis,we got the data:ejection fraction (EF),16 segments systolic dyssynchronic index (SDI 16).All subjects should take the coronary angiography.According to coronary angiography results,the patients with the vascular stenosis rate ≥50% were defined as the CAD group,and the patients with the vascular stenosis rate <50% were defined as the coronary atherosclerosis group,the patients with the completely normal angiographic results were included in the control group according to the results of angiography.The parametric differences among the groups were compared.Results There was no significant difference in LVEF among the three groups.SDI 16 had no significant difference between the control group and the coronary atherosclerosis group (t=-1.03,P>0.05).However,SDI 16 had significant difference between the control group[(3.72±2.68)%]and the CAD group[(7.14±3.10)%],the same between coronary atherosclerosis group[(5.12±3.46)%]and the CAD group[(7.14±3.10)%](t=-3.71,-2.34,all P<0.05).ROC curve analysis revealed that a cut-off value for SDI of 5.49%,yielded a sensitivity of 81.8%,with a specificity of 73.1% to predict coronary atherosclerosis to CAD(AUC=0.743).Conclusion SDI 16 >5.49% has a higher value in evaluating systolic dyssynchrony in patients with CAD with RT-3D of Siemens Acuson SC2000 ultrasonic diagnostic instrument.

An indexing system is constructed,based on the implementation of prevention and control technology for chronic non-communicable diseases in community health service institutions,using both literature review and Delphi method,and using the Analytic Hierarchy Process (AHP) to calculate the weight of the indexing system.The system comprises three level-1 indexes,8 level-2 indexes and 33 level-3 indexes.The research proposed a transition from emphasis of therapeutic means to prevention,and emphasis on prevention and control technologies to the high-risk population in the prevention and control technology of chronic non-communicable diseases,along with development of techniques and measures to encourage behavioral changes of the population with chronic diseases.

Objective To explore the preliminarily clinical value of strain rate parameters using velocity vector imaging (VVI) evaluating left ventricular regional endocardial systolic function in patients with coronary artery heart disease (CAD).Methods A total of eight six inner subjects who were suspected as CAD was enrolled in the study.Patients with the vascular stenosis rate ≥ 50％ were defined as the CAD group,patients with the vascular stenosis rate ＜ 50％ were defined as the coronary atherosclerosis group,and patients with the completely normal angiographic results were included in the control group,according to the results of angiography.The left ventricular endocardial systolic strain rate parameters of VVI were obtained in standard long axis views (apical two,three,and four-chamber view) and short axis views (at the level of the mitral valve,papillary muscles,and apex).The strain rate parameters were global longitudinal endocardial systolic strain rate in the apical two,three,and four-chamber views (A2-GLSRs,A3-GLSRs,and A4-GLSRs),global radial endocardial systolic strain rate in short axis view of the mitral valve level,papillary muscles,and apex (MV-GRSRs,PM-GRSRs,and AP-GRSRs),and global circumferential endocardial systolic strain rate in short axis view of the mitral valve level,papillary muscles,and apex (MV-GCSRs,PM-GCSRs,and AP-GCSRs).The parametric differences were compared among three groups.Results All the subjects included in the present study had normal left ventricular ejection fraction (LVEF) and there was no significant difference in LVEF across three groups.Compared to other groups,the control group had significantly higher E/A ratio.The LV endocardial systolic strain rate parameters were all significantly reduced in the CAD group compared to the control group and the coronary atherosclerosis group (all P ＜ 0.05).Compared to the control group[(-1.37 ± 0.25)/s],the coronary atherosclerosis group [(-1.12 ± 0.42)/s] had significantly lower MV-GCSRs (P ＜0.01).Conclusions VVI is useful for quantitative assessment of the left ventricular systolic function in CAD.MV-GCSRs might have the potential to predict early left ventricle (LV) systolic dysfunction in subjects with coronary artery stenosis ＜ 50％.

BACKGROUND:A series of pathological changes were found in atlas, including atlas dislocation, atlanto-occipital junction instability and vertebral fractures. Atlantoaxial pedicle screw, nail and rod fixation or nail plate fixation is a novel repair method recently proposed, and has certain advantages. OBJECTIVE:To compare the repair effects of atlas pedicle screw on different types of atlas lesions. METHODS:A total of 42 fresh vertebrae were obtained from Department of Human Anatomy, Basic Medical School, Inner Mongolia Medical University. In accordance with bone thickness of sagittal vertebral artery groove bottom, vertebrae were divided into three types:type I (common type), type II (light variation), and type III (severe variation). Al samples were subjected to atlas pedicle screw fixation. RESULTS AND CONCLUSION:The screw pul out force in different bone densities of vertebrae was not the same. Vertebrae with great thickness and great bone density had big screw pul out force (P<0.05). However, the screw in different cortical bone of vertebrae had the same function. No compression on blood vessels or phenomenon affecting vertebral activity was visible. These results indicated that atlas pedicle screw implantation showed good safety, no side effects, did not affect the normal work and life of patients.

The prognosis of malignant tumors of the digestive system is still a matter of close attention in the medical and health field. At present, evaluating the prognosis of patients with digestive system malignant tumors is mainly based on the TNM staging of the tumor after surgery. As one of the ten characteristics of cancer, inflammatory indicators have certain guiding significance for the prognosis and treatment of patients with malignant tumors of the digestive system. As a new type of inflammation index, the systemic inflammatory response index is significantly better than other traditional inflammatory indexes in evaluating the prognosis of patients with digestive system malignant tumors. This article reviews the related studies on the systemic inflammatory response index in evaluating the prognosis of digestive system malignant tumors.

Objective To explore the endoscopic managements for biliary and pancreatic diseases in patients with the history of complex gastrointestinal surgery.Methods Data of four patients who underwent balloon-assisted enteroscopy after complex digestive surgeries (2 patients underwent Roux-en-Y reconstruction,2 others Whipple reconstruction) were retrospectively collected.One patient with bilio-intestinal anastomosis was explored by double-balloon enteroscope (DBE),and balloon-assisted enteroscopy combined with ERCP was used for other 3 patients.Results Therapeutic ERCP was successfully performed on one patient,and the diagnosis of 3 others were confirmed.No operation-related complications such as bleeding or perforation was observed.Conclusion Balloon-assisted enteroscopy combined with ERCP is an important diagnostic and therapeutic method for biliary and pancreatic diseases in the patients after complex gastrointestinal surgery.

Benign biliary stricture is a challenging problem in hepatobiliary surgery. Benign biliary stricture is associated with major portal vein variation, which is not be found in literatures. A male patient with benign biliary stricture was admitted to the Chinese PLA General Hospital in March, 2010.The stricture was located in the hilar confluence with intrahepatic biliary dilation and hepatolithiasis. The result of computed tomography showed that the hilar biliary confluence was compressed by the left portal vein and right anterior portal vein. The patient was cured after receiving gallbladder interposition, choledocholithotomy and T tube drainage. We suggested that the benign hilar biliary stricture due to portal vein variation may be named as biliary nut-craker syndrome.

Objective To investigate the clinical value of anatomic M-mode echocardiography (AMM)for pristine diagnosis of myocardial ischemia in patients with coronary heart diseases (CAD).Methods 44 inner patients who were suspected as CAD were detected.Ordinary ultrasound was performed first.The ventricular segmental wall thickness and amplitude were measured by AMM.Then,we got the ventricular wall thickening fractions.All subjects should take the coronary angiography after the ultrasound examination in 1 -3 days.Patients with the vascular stenosis rate≥50% were defined as the CAD group,patients with the completely normal angiographic results were included in the normal control group according to the results of angiography.The parametric differences between the patients and the normal control subjects were compared.Results In the normal control subjects,the ventricular segmental wall amplitude >5mm accounted for 78.67%,the ventricular wall thickening fractions >30% accounted for 99.13%.But in CAD group,the ventricular segmental wall amplitude <4mm accounted for 61.14%,<5mm accounted for 93.47%,the abnormal ventricular wall thickening fractions <30% accounted for 88.43%.The sensitivity, specificity,accuracy of AMM were 77.47%,90.00%,77.39% respectively.Conclusion The ventricular wall thickening fractions of AMMhas quite significant correlation with morbid blood vessel in patients with CAD,they are effective reference indicators to evaluate the left ventricular wall motion quantitatively.

Objective: To explore the application and effect of superficial temporal fascia flap combined with avulsion auricular tissue in emergency auricular restoration. Methods: From June 2015 to December 2015, 6 patients with auricular large area complete avulsion were underwent treatment in Department of Plastic Surgery of General Hospital of Shenyang Military. After thorough debridement, the auricular cartilage scaffold of the avlusion ear and skin was completely stripped. The auricular cartilage was repositioned on its anatomical site and subsequently covered by superficial temporal fascia flap. The free skin was stripped as full-thickness graft to cover the surface of reconstructed ear. Results: All 6 patients with auricle large area complete avulsion achieved immediate repair under emergency condition. The operations were successfully completed and the ears were healed primarily. The patients were followed-up for one year. Five patients with partial auricular avulsion achieved obvious reconstructed auricle profile. The color of reconstructed ear was close to the surrounding skin and the cranioauricular angle was nearly normal. Patients and their families were very satisfied. One patient of total auricular reconstruction had auricular contracture. The auricle profile was not obvious with small size, morphological changes and external auditory canal stenosis. Conclusions Avulsion auricle and temporal superficial fascia flap can be used to repair partial auricle defects as a first-stage repair with ideal results. It is the best choice for large auricle defects in emergency cases.

Paclitaxel and cephalomannine contents in wild Taxus cuspidata were determined by HPLC. The results indicated that paclitaxel and cephalomannine contents in T. cuspidate at the sunny side were slightly higher than that at the shadow side in the current-year and biennial branches. Paclitaxel and cephalomannine contents had no obvious regularity in leaves. Paclitaxel and cephalomannine contents were both the highest in the bark, then in the current-year branches, lower in the current-year leaves, and the lowest in the fruits. There were no remarkable correlation between stem diameter and paclitaxel and cephalomannine contents in the current-year branches and leaves. Significant difference was observed among samples collected in different period, and higher paclitaxel and cephalomannine concentrations were detected at the dormancy stage than that at the flower and fruit stages.
