The clinical and electrocardiographic data of 35 cases with CAVB were analyzed. They could be divided into two groups: chronic (28 cases) and transcient(7 cases). The primary diseases of the patients in the chronic group were coronary heart disease(CHD) in 11 cases, a condition of unknown cause in 12, and miscellaneous diseases in 5.The clinical and ECG manifestations of the 12 cases with unknown cause were suggestive that the disorder was most likely to be primary degeneration of conduction bundles(PDCB). PDCB differed from CHD by the following:(1) In PDCB, there was neither history of chest pain nor factors vulnerable to CHD being found. No ischemic changes cound be found on the ECG of PDCB cases.(2) The duration of CAVB was longer in PDCB cases (mostly over 3 years) than in CHD cases (all under 2 years).(3) The onset of CAVB occurred at a younger age in PDCB(an average of 50.6 years) than in CHD(an average of 66.3 years).The difference between the two was significant(P

ObjectiveTo explore the value of three-dimensional speckle tracking (3DT-STI) technique for evaluating end-systolic three-dimensional longitudinal strain (3DLSe) of left ventricular myocardium in patients with left anterior descending coronary artery (LAD) lesions.MethodsSixty patients with pure LAD lesions diagnosed by coronary artery angiography (CAG) in Taizhou Hospital from June 2012 to December 2014 were enrolled, including 30 patients with acute anterior wall myocardial infarction (infarction group) and 30 patients without acute anterior wall myocardial infarction (non-infarction group). Sixty patients in the control group were enrolled in Department of cardiology in Taizhou Hospital in the same period. 3DLSe within LAD blood-supplied region, adjacent region and remote region were analyzed in all cases using 3DT-STI. The 3DLSe differences of 3 groups were compared by one-way analysis of variance, and the 3DLSe differences between two groups were compared by the LSD-t test. The inter-observer and intra-observer consistency of 3DLSe of left ventricular myocardium were analyzed by Bland-Altman drawing analysis method.Results3DLSe of all 7 segments within LAD blood-supplied region were lower in infarction group than those of non-infarction group and control group, and the differences were statistically significant (infarction groupvs. control group:t values were 6.96, 7.41, 8.94, 8.23, 8.94, 12.09 and 15.99, respectively,P values were all less than 0.01; infarction groupvs. non-infarction group:t values were 5.30, 5.50, 4.66, 4.32, 4.66, 7.66 and 10.11, respectively, P values were all less than 0.01); 3DLSe of middle anterior segment, middle anterior septal segment, apical anterior segment, apical septal segment and apex of heart within LAD blood-supplied region were lower in non-infarction group than those of control group, and the differences were statistically signiifcant (t values were 3.56, 3.23, 3.02, 3.25 and 4.36, respectively,P values were all less than 0.01), but 3DLSe of basal anterior segment and basal anterior septal segment had no statistically significant difference. 3DLSe of basal inferior septal segment within LAD adjacent region had no statistically significant difference in all 3 groups. 3DLSe of basal lateral segment, middle inferior septal segment, middle lateral segment, apical inferior segment and apical lateral segment within LAD adjacent region were lower in infarction group than those of non-infarction group and control group, and the differences were statistically signiifcant (infarction groupvs. control group:t values were 4.15, 4.79, 4.58, 9.24 and 12.07, respectively,P values were all less than 0.01; infarction groupvs. non-infarction group:t values were 2.66, 3.59, 4.29, 7.74 and 10.33, respectively,P values were all less than 0.01); but 3DLSe of basal lateral segment, middle inferior septal segment, middle lateral segment, apical inferior segment and apical lateral segment within LAD adjacent region had no statistically significant difference between non-infarction group and control group. 3DLSe of all 4 segments within remote region had no statistically significant difference. Bland-Altman drawing analysis method showed the mean inter-observer and intra-observer difference of 3DLSe of left ventricular myocardium were-0.3% and-0.2%, the 95% conifdence interval (CI) were in the range of (-5.6%, 5.0%) and (-8.2%, 7.7%), respectively. It was demonstrated that 3DLSe of left ventricular myocardium had good inter-observer and intra-observer consistency.Conclusions3DLSe of left ventricular myocardium can detect the subtle changes in myocardial systolic function and is more sensitive than the conventional echocardiography. It can localization and analyze quantitatively the range of myocardial ischemia or infarction and has good consistency.

Objective To survey the current living situation, protection condition, suggestions and demands of protective items and inheritors of TCM intangible cultural heritage;To analyze existing problems and solutions of protection;To lay the foundation for further protection. Methods Survey was carried out through table investigation and meeting and convention from the aspects of item overview, situation of inheriting community, protection status, and demands and suggestions. Results TCM intangible cultural heritage is inherited through traditional teaching and learning between masters and apprentices, and family inheriting. Some inheriting communities are too small, and some inheritors are too old, which make the inheriting prospect quite gloomy. Protective levels of items of TCM intangible cultural heritage vary. Most items are protected by protective institutions, protective personnel, and learning-teaching sites. Some items are supported by protective fund;archive data about the items are filing;researches and work about propaganda and education are also carried out. Conclusion Protection of TCM intangible cultural heritage has made certain achievements. However, some problems about funds, inheriting, filing, training, and propagandizing should be solved.
