Basic & Clinical Medicine 2015;(1):1-6
Objective Obese patients with type 2 diabetes mellitus ( T2DM) characterized by hyperglycemia are li-able to more severe myocardial infarction .Semen Cassiae is proved to reduce serum lipid level .This study was to investigate whether the Semen Cassiae extract (SCE) reduces myocardial ischemia and reperfusion (MI/R) injury with or without diabetes and the underlying mechanisms .Methods The high-fat diet-fed streptozotocin ( HFD-STZ) rat model was used as T2DM model.Normal and DM rats received SCE treatment orally (10 mg/kg/day) for 1 week.Subsequently these animals were subjected to MI /R.Results Compared with the normal animals , DM rats showed increased plasma total cholesterol ( TC) and triacylglycerol ( TG) , more severe MI/R injury and cardi-ac functional impairment .SCE treatment significantly reduced the plasma TC and TG , improved the instantaneous first derivation of left ventricle pressure and reduced infarct size , decreased plasma creatine kinase and lactate dehydrogenase levels, and reduced apoptosis index at the end of reperfusion in diabetic rats .Moreover, SCE treat-ment increased the antiapoptotic protein Akt and stimulated ERK 1/2 phosphorylation .Pretreatment with a PI3 K in-hibitor wortmannin or an ERK1/2 inhibitor PD98059 not only blocked Akt and ERK1/2 phosphorylation, but also inhibited the cardioprotective effects of SCE .However , SCE treatment did not show any effects on the MI/R injury in the normal rats.Conclusions SCE effectively improves myocardial function and reduces MI/R-induced injury in diabetic but not normal animals , which is potentially attributable to the reduced TC/TG levels and the triggered cell survival signaling Akt and ERK 1/2 .

Objective To observe the distribution of different ventricular myocardial band segment's in different echocardiogram sectiones. Methods 5 swine hearts, 5 ox hearts and 5 sheep hearts were dissect to the ventricular myocardial band structure by the standard anatomy method. After the demarcation line of each segment of ventricular myocardial band was defined, they were dyed with different colors and then were recovered into the state before dissecting. At last, they were cut open according to different echocardiogram sectiones. Results With relative stabile anatomy methods, all hearts presented to be a unique integrate myocardial band,with two loops, the basic loop and apical loop, and four segments. At different echocardiogram sectiones, the left ventricle is formed by three muscular strata, while the right ventricle is formed by only one muscular strata. Conclusion The distribution of different ventricular myocardial band segments in different echocanliogram sectiones is significantly different.

Objective By dissected and decomposed the boiled rabbits' hearts to study the space courser of ventricular myocardial band of the normal heart architecture. Methods 10 rabbit hearts were boiled and dissected as described by Torrent-Guasp. All myocardial bands were decomposed and tagged, then recovered to the state when they hadn't been dissected, and then X-ray photos were taken. Results The myocardial band twists on itself extends from the origin of the pulmonary artery to the root of the aorta. This defines two turns in a helical fashion and delimitates two cavities, the right and left ventricles. The reciprocal fiber angle within descending and ascending segments of the apical loop was about 90?. The interventricular septum is formed by three muscular strata: right segment, descending segment and ascending segment. Conclusion Our study shows that the reciprocal fiber angle within descending and ascending segments of the apical loop is about 90? and the interventricular septum is formed by three muscular strata.

0.05). The length percentage of the ascending segment and the weight of the descending segment were greater than other segment in all hearts. The myocardial band twists on itself extends from the origin of the pulmonary artery to the root of the aorta. This defines two turns in a helical fashion and delimitates two cavities, the right and left ventricles. Conclusion Our study shows that the concept of ventricular myocardial band is a truly basic architecture of the heart.

BACKGROUND: Undergraduates from military medical universities face many psychological stresses. Poor coping style might affect the status of mental health. Mental health might also be associated with social support and personality.OBJECTIVE: To investigate the correlation of social support and coping style with mental health among undergraduates from military medical universities.DESIGN: Cluster sampling and questionnaire investigation.SETTING: The Center of Basic Medicine Eexperiment, School of Basic Medicine and School of Preventive Medicine of Fourth Military Medical University of Chinese PLA, and Xi'an Hospital of Sports Trauma.PARTICIPANTS: Totally 352 freshmen of a military medical university were chosen by cluster sampling in October 2004 as the subjects.METHODS: Investigationwas performed on subjects with Symptom checklist-90 (SCL-90), social support rating scale (SSRS), coping style questionnaire (CSQ) and revised Eysenck's personality questionnaires short scale for Chinese (EPQ-RSC).SCL-90 consists of 90 items, including 10 factors. SSRS consists of subjective support, objective support and the utilization of support 3 factors as well as total score of social support. CSQ consists of problem solving, self-reproach, asking for help, keeping out of the way, fancy, rationalization 6 factors. EPQ-RSC mainly consisted of extraversion-introversion (E), neuroticism (N), psychoticism/tough mindedness (P) and lie/social diserability (L) 4 dimensions. Data were performed statistical management with t test and correlation analysis.MAIN OUTCOME MEASURES: ①Comparison of the scores of various factors of social support, coping style and personality among undergraduates with different mental health levels from military medical universities. ② Correlation of different social supports, copying styles and personalities with SCL-90. ③ Comparison of scores of mental health,coping style and personality of military medical undergraduates under different social supports.RESULTS: Totally 352 questionnaires were handed out and all of them were retrieved and eligible, with responding rate of 100%. ① The total scores of SRSS were taken as the grouping index, and 25% of the undergraduates who had the highest scores and the lowest scores were respectively chosen as severe symptom group and mild symptom group.Total scores of social support, subjective support and the utilization of support were higher in the mild symptom group than in the severe symptom group, but no difference in the objective support existed between two groups; Compared with mild symptom group, self-reproach, fancy, keeping out of the way and other immature coping styles were more significantly used, but asking for help was less, the scores of E were lower, but those of N were higher in the severe symptom group. ② Various factors of mental health were significantly negatively correlated with the total scores of support, the utilization of support, asking for help, E and L (r=-0.131 to -0.306 ,P < 0.05 or P < 0.01 ), but positively correlated with self-reproach,fancy, keeping out of the way, rationalization and N (r=0.141-0.450, P< 0.05 or P < 0.01). ③ Total scores of support was used as the grouping index, 27% of the subjects who had the highest scores and lowest scores were chosen respectively as high support group and low support group.Mental health level was superior in the high support group to in the low support group; Most of the undergraduates of high support group preferred active coping styles, and those of low support group preferred passive coping styles; Scores of E of high support group were higher than those of low support group, and the scores of N and P were lower than those of low support group (P < 0.05).CONCLUSION: Social support, coping style and EPQ-RSC interact and co-influence mental health.
