Objective Analyse the change of left ventricular (LV) longitudinal and radial strain in patients with aortic regurgitation (AR) and discuss the relationship between the 2D strain parameter and the filling and ejection of LV. Methods Thirty healthy controls and 45 patients with AR (24 patients with moderate AR and 21 with severe AR) were enrolled in this study, LV systolic global peak radial strain(GRS), systolic global peak longitudinal strain(GLS) and systolic peak longitudinal strain(S), systolic peak longitudinal strain rate(SRs), early diastolic peak longitudinal strain rate(SRe) of every segment were measured or calculated using 2D-STE, early and late diastolic transmitral flow velocity (E, A) were recorded by pulsed Doppler echocardiography and early diastolic mitral annular velocity (Ea) were assessed by tissue Doppler imaging,the E/A and E/Ea ratio were calculated. Discuss the relationship of GLS and LV ejection fraction (LVEF), GLS and E/Ea using the Pearson correlation analysis. Results The GLS were (-20.09±1.47)%, (-18.68±1.52)%, (-12.56±3.25)%and the GRS were (46.71±7.65)%, (43.01±5.95)%, (28.52±6.13)% in control group, patients with moderate and severe AR (MAR group and SAR group) respectively. There were significant differences among the groups (F =82.08,47.69, both P < 0.01) as following:SAR group with control group and MAR group [ q=17.56,13.60 (GLS), q=13.44, 10.20 (GRS), all P<0.01),MAR group and control group [ q=3.42 (GLS), P<0.01]. The SRs of the apical segment were (-1.24±0.22)s-1, (-1.19±0.25)s-1, (-1.04±0.28)s-1 in control group,MAR group and SAR group respectively. There were significant differences among the groups (F=4.47, P < 0.05) as following:SAR group with control group and MAR group ( q=4.02,3.28, both P<0.01). The S, SRe of apical segment and the S,SRs,SRe of basal and midventricular in MAR group were all lower than the control group ( q=4.42, 5.01, 3.48, 3.24, 4.78, 4.12, 3.61, 6.72, all P < 0.01). Pearson correlation analysis revealed the GLS had a relationship with LVEF and E/Ea ( r=-0.73, 0.64, both P<0.01). Conclusion The reduced longitudinal strain and strain rate could detect LV dysfunction in patients with AR in early stage and the GLS had the ability to reflect the diastolic filling and systolic ejecting of the LV.

A procedure descried by Fontan and Baudet in 1971 successfully bypassed the right ventricle in Tricuspid Atresia patients, after then many modification of the Fontan operation had been described and applied to many cyanotic complex heart patients. Forty patients with a variety of cardiac malformation underwent the Fontan operation at Seoul National University hospital (September 1978 to June 1986). The age at operation ranged 2 months to 18 years. Each number of cases according to basic cardiac anomaly was as follows; 17 in Tricuspid Atresia, 17 in Univertricular Heart, 2 in Double outlet of Right Ventricle, 2 in Transposition of the Great Arteries and 2 in Criss-cross heart. Total mortality rate after the Fontan operation was 50%. There was only one late death (>30 days). Mortality rate under 4 years of age (67%) was higher than that between 4 and 18 years of age (40%). we observed a significantly higher mortality for patients who, in the immediate postoperative period, had central venous pressure greater than 25cm H2O. 45% among survivals did not require further medication. Although mortality rate after the Fontan operation is much higher than that in the foreign literature, operative mortality will decline with the increased expirence of surgeon and the effective patients selection.

In order to observe the development of ventricular arrhythmia during regional myocardial ischemia and reperfusion, especially under the presence or absence of ST-T electrical alternans on epicardial EKG. The proximal left descending coronary artery(LAD) was ligated for 20 minutes and then reperfused suddenly in twenty-three cats. Standard lead EKG(Lead??, chest lead EKG and epicardial lead EKG were recorded simultaneously during the occlusion and reperfusion respectively. During the ligation of LAD, STEA was observed in thirteen cats(56.5%). In occlusion period, the incidence of ventricular tachycardia in STEA positive group was significantly higher than in the negative group(p<0.01) and arrhythmic score was significantly higher(p<0.005) also In the reperfusion period the incidence of vefntricular fibrillation in STEA positive group was significantly higher than in the negative group(p<0.025). But there was the tendency to be higher in arrhythmic score of STEA positive group. There were no differences in heart rate, systolic left ventricular pressure, ST elevation and ST width in both groups. Most forms of ST-T of sinus rhythm before and after development of ventricular premature beat was low form(L). It was concluded that at the presence of STEA on EKG, the incidence of ventricular arrhythmia was more prevalent. So, STEA can be available as a marker of ventricular arrhythmia and prognostic factor.

OBJECTIVETo investigate the feasibility and clinical application value of selecting viable spermatozoa by noncontact diode laser.

METHODSWe obtained immotile spermatozoa from 2 infertile men with obstructive azoospermia or severe asthenospermia and selected viable spermatozoa using a single laser shot at the sperm tail. Those that responded to the laser shot by a curling reaction of the tail were regarded as presumably viable and used for intracytoplasmic sperm injection (ICSI).

RESULTSThe mean fertilization rate was 88.89% after ICSI with the laser-selected viable spermatozoa. Both of the embryo transfers resulted in a single pregnancy.

CONCLUSIONNoncontact diode laser is a useful alternative for the assessment of sperm viability, which may help to achieve successful pregnancy.

OBJECTIVE To have a systematic pathomechanism view of three chest impediment-syndromes of Qi Deficiency and Blood Stasis syndrome(QDBS),Qi Stagnation and Blood Stasis syn-drome (QSBS), Cold Obstruction and Qi Stagnation syndrome(COQS) and further investigate the changed metabolome and related pathways for screening potential biomarkers in rat plasma. METHODS According to clinical pathogeny, three kinds of syndrome models were established to simulate the disease of chest impediment. Plasma metabonomics based on UPLC-Q-TOF/MS was applied in this research to detected small molecule metabolites for identifyingthe special potential biomarkers of three chest impediment syndromes, respectively. RESULTS Significant metabolic differences were observed between thecontrol group and three syndrome groups. Furthermore, three syndrome groups were distinguished clearly by pattern recognition method.The particular metabolites contributing most to the classification of three chest impediment syndromes were identified. In the QSBS group, the potential biomarkers could include 2-keto-glutaramic acid, L-methionine, L-homocysteic acid, octadecanamide, stearoylglycine,behenic acid,linoleylcarnitine,lysoPC(14:1(9Z)),indoxyl sulfate and cholic acid.In the COQS group, they could be aminoadipic acid, palmitic amide, oleamide, lysoPC(P-16:0), lysoPC(P-18:0), lysoPC(20:2(11Z,14Z)), 9-HETE and tauroursodeoxycholic acid. Moreover, 4-pyridoxic acid, L-palmi-toylcarnitine, lysoPC(20:0), lysoPC (22:5 (4Z,7Z,10Z,13Z,16Z)), 3- hydroxyhexadecanoic acid and arachidonic acid could be the potential biomarkers for the QDBS group. CONCLUSION Three chest impediment syndromes have their own potential biomarkers.Each special metabolite has its owndifferent metabolic pathway.Both metabolismof cysteine and methionine,and metabolism of alanine,aspartate and glutamate are the main pathways in regulation of metabolic disorders in QSBS syndrome. Lysine biosynthesis and degradation,fatty acid metabolism,and glycerophospholipid metabolism are the main pathways in regulation of metabolic disorders in COQS syndrome.Arachidonic acid metabolism, fatty acid metabolism,fatty acid elongation in mitochondria,and vitamin B6 metabolism are the main pathways in regulation of metabolic disorders in QDBS syndrome.These endogenous substances were indicated as the special potential biomarkers for three chest impediment syndromes and worth studying in depth.

Abstract: Objective To understand the mental health literacy level of residents in Hainan Province, and to provide evidence for promoting mental health promotion and improving the mental health literacy level of residents. Methods Multi-stage random sampling method was used to investigate The National Mental Health Literacy Questionnaire among 6 895 residents in 12 districts including Changjiang, Chengmai, Dongfang, Ledong, Lingshui, Haikou Longhua District, Haikou Meilan District, Qionghai, Sanya, Tunchang, Wenchang and Wuzhishan. Results　In the survey 6 895 residents in 12 counties, cities, districts of Hainan Province, 365 of them reached the standard of mental health with the standard rate of 5.3%. The mental health knowledge score was (54.00±17.02) with the standard rate of 7.7%; the self-assessment score was (26.11±3.99) with the standard rate of 75.9%; the score of mental health skill was (26.22±7.25) with the standard rate of 44.8%. The mental health literacy level of medical workers was the highest, with the standard rate of 13.5% (112/830), and the mental health literacy level of farmers was the lowest, with the standard rate of 0.8% (13/1 647). The results of unconditional Logistic regression showed that the factors entering the regression model included educational background (OR=2.268), personal monthly income (OR=1.129), gender (OR=1.302), household registration (OR=0.776), and whether they had participated in mental health related courses OR training (OR=0.511). The higher the educational background and personal monthly income, the higher the psychological quality. The mental health of women was higher than that of men, and that of urban was higher than that of rural, and those who had participated in mental health related courses were higher than those who had not. Conclusions The mental health literacy level of Hainan residents is at a low level, and the influencing factors are multifaceted. It is suggested to strengthen the mental health monitoring comprehensively and carry out rich health education service mode for different groups.

Objective To explore the effects and nursing of biventricular resynchronization therapy on the treatment for patients with congestive heart failure.Methods NYHA grade of heart function,ORS duration of electrocardiogram,left ventricular ejection fraction ( LVEF),exercise tolerance of walking distance in 6 min were compared among 63 patients with congestive heart failure before and after they received biventricular resynchronization therapy.And the nursing measures for patients were summarized.Results Six months later after patients received such therapy,NYHA grade from (3.40 ± 0.50) that of preoperation improved to(2.30 ±0.60),ORS duration from preoperation( 144.68 ± 16.40) ms reduced to( 100.02 ± 14.76 ) ms,LVEF( ％ ) from (33.18 ±5.60 )increased to(41.08 ±7.45),walking distance in 6 min from(305.40 ±30.30)m improved to (406.20 ± 70.50) m,differences were statistically significant ( t =11.18,4.562,6.728,10.426; P ＜ 0.01 ).There was no patient died during 3 months - 24 months postoperation follow up.Conclusions Biventricular resynchronization therapy is one of effective treatments for patients with congestive heart failure,which can obviously improve heart function and life quality of patients.At the same time,it is important to ensure psychology nursing before operation, electrocardingraphy during operation, observation after operation,complication prevention,follow up and so on to be done very well.
