Objective To assess ventricular function of early stage neonates of different gestational ages by tissue doppler imaging(TDI).Methods Pulsed wave TDI velocities were obtained in 36 cases of premature infants with gestational ages of 32 to 36 weeks(premature group) and 33 cases of full-term infants(full-term group) aged 3 to 7 days at the lateral mitral annulus(MA),basal septum,and lateral tricuspid annulus(TA) during ventricular systole(Sa),early diastole(Ea),late diastole(Aa).Tansmitral and transtricuspid inflow were also obtained through pulsed doppler echocardiography.Results Ea and Sa in all of 3 locations were lower in the premature group compared with that of the full-term group,and Ea/Aa in TA was lower in premature group,but Aa and E/Ea showed no difference between 2 groups.Ea and Sa showed a positive correlation with gestational age and birth weight.Conclusions Ventricular systolic and diastolic function in premature infants are poorer than that in full-term infants in the early stage of neonatal period,and ventricular function is related to intra-uterus growth and maturity of the newborn.Diastolic function of the left ventricle in both groups develops rapidly during the early stage of neonatal period.

Objective To study immunoregulatory activity of polysaccharide of mudan cortex (PSM) on immunodepressive mice. Method The immunodepressive mice model was established with cyclophosphamide treated and tumor-bearing. PSM was orally administered to mice for 10 d. MTT method was used to observe the prolifernation of lymphocytes. The function of macrophage in abdominal activity was measured. Sectrophotometric determination was adopted to evaluate the ability of plaque forming cell. Result PSM could enhance the function of macrophage, increase the content of plaque forming cell, and promote the prelifernation of lymphocytes. Conclusion PSM could enhance immunofunction of immunodepressive mice.

The postpartum depression outcome and the effect of psychological intervention were studied in order to reduce the occurrence and development of the postpartum depression. A survey of 4000 women within 4-6 weeks postpartum in 80 communities in Shenzhen, China was performed using random cluster sampling method. By employing Edinburgh Postnatal Depression Scale (EPDS) as a screening tool, the positive women (defined as EPDS ≥10) were randomly divided into intervention group and control group at a ratio of 1:2. The women in the intervention group were treated by means of mailing postpartum depression prevention and treatment knowledge manual, face-to-face counseling, and telephone psychological counseling interventions aiming at individual risk factors, while those in the control group were treated with conventional methods. EPDS scores were assessed in these two groups again at 6th month postpartum. Totally, 3907 valid questionnaires were obtained. All the 771 positive women were divided into two groups: 257 in the intervention group, and 514 in the control group. At 6th month postpartum, the EPDS scores in the intervention group were decreased significantly, from baseline stage (12.84±3.02) to end stage (3.05±2.93), while EPDS scores in the control group were reduced from 12.44±2.78 to 6.94±4.02. There were significant differences in the EPDS scores at end stage between the two groups (t=13.059, P<0.001). Psychological intervention can reduce postpartum depression, with better maternal compliance. It is feasible and necessary to establish postpartum depression screening and psychological intervention model in community-hospital and include the postpartum depression screening, intervention, and follow-up into the conventional healthcare.

Objective To survey the satisfaction degree of the postgraduates in professional degree with The Joining Together of Double-Track education model in the current stage of professional degree graduate education and standardized training of residents in China. Methods According to various factors, such as the current situation of postgraduates in medical universities, we sought the opinions of relevant experts to design questionnaire. Meanwhile, to enhance the reliability of the questionnaire and the survey, we chose the postgraduates of Shengjing Hospital of China Medical University first to do the pre-survey, and according to the feedback, we adjusted part of the aspects, thus formed a formal questionnaire, which included the satisfaction with training of clinical practice ability, training of research ability, and tutors' assessment etc. Finally, the Chinese New Youth Forum online released the questionnaires, selecting the postgraduates in professional degree who were participating in, or had participated in the completion of the standardized training as the participants, which took place between March 2016 and May 2016. SPSS 16.0 was used for statistical analysis. The evaluation results of different majors were tested by Kruskal-Wallis rank sum test. Results According to the results of the survey, the aspects in the clinical resident standard-ized training that the 1000 postgraduates were more satisfied with were as follows: training time [42.8%(n=428)], training center [41.8% (n=418)], training of clinical practice ability [41.6% (n=416)], tutors [40.2%(n=402)], economic income [38.8%(n=388)], department arrangements [38.4% (n=384)], training of research ability [37.5%(n=375)]. There is a significant difference in the satisfaction degree of different pro-fessional graduate students in theJoining Together of Double-Trackeducation model (P<0.05). ConclusionThe Joining Together of Double-Track education model should be compatible with the training objectives of postgraduates in professional degree. Much more attention should be paid to the post-graduates, satisfac-tion degree with the clinical resident standardized training, as well as the requirements during the training period, improve the evaluation of graduate students' ability of scientific research, econo-mic income and so on, so as to improve the training system for the postgraduates.

Objective To analyze the tendency of road traffic injuries and explore its main influencing factors in China from 1997 to 2016, so as to provide references for decision-making of prevention and control. Methods Data was collected from national data website. Annual percent change (APC) and average annual percent change (AAPC) were calculated and trend tests were performed by Joinpoint Regression Program 4.6.0.0. Results The overall trend of the indexes was basically the same, reaching the highest record in 2002. The following downward tendency was different and tended to level off after 2009. However, the forecast showed that the fatality of road traffic accidents would increase slightly in recent years. For different road traffic modes, only the average annual percent change of motor vehicle injuries statistically descended (AAPC=-1.83, Z=-2.23, P=0.026). The average annual decreases of non-motor vehicle deaths were statistically significant (AAPC=-1.98, Z=-2.47, P=0.014), and the number of injured showed a notable upward trend instead (AAPC=3.95, Z=5.16, P<0.001). The indexes of walking and riding were declined markedly (AAPC≥7.90, P<0.001). Conclusions The status of walking and riding had been improved significantly, but motor vehicles injuries were still the main traffic mode causing road traffic injuries. The safety situation of non-motor vehicles was increasingly serious. Adopting legal compulsory measures and other intervention to routine systematic management was quite necessary.
