Coronary heart disease(CHD) is the leading cause of death among women worldwide.Recent technological advances in cardiovascular diagnosis and treatment have not led to significant declines in mortality for women with CHD when compared to the dramatic declines for men.Owing to the gender differences of physiology and social circumstances,women with CHD may have different manifestations as compared to men with CHD.Recently,research has shown that women with CHD had mainly the following characteristics:special risk factors,atypical ischemia symptoms,multiple risk factors and comorbidities at initial physician consultation,higher under-treatment rate and higher mortality rate.At the same time,most CHD researches have paid little attention to women.Therefore,the current CHD guidelines may not be completely suitable for women.In order to improve the prevention and treatment of CHD in women,we advocate to enhance research and clinical work for women with CHD.

Objectives To explore status of health prevention knowledge awareness and the formation of healthy behaviors of community residents in Guagzhou and provide evidence for health-management-related departments to put forward pertinent intervention strategies. Methods A questionnaire-based survey was conducted among 2 790 community residents in Guangzhou by multistage stratified random sampling. Results The awareness rate of residents′ basic health prevention knowledge was 78.14%, the awareness rate of key knowledge was 74.77%, the rate of health behavior formation was 48.14%. The rate of women′s behavior formation was higher than that of men′s. The awareness rate of basic knowledge among the residents aged over 50 years was lower than that that among those aged less than 50 years , but the awareness rate of key knowledge and behavior formation rate were higher. The level of knowledge awareness and the rate of behavior formation rate of urban residents were higher than those of rural residents and migrants. The knowledge awareness and behavior formationi were positively correlated with degree with statistically significant difference (P < 0.01). Conclusions The health belief and behavior of the community residents should be cultivated and strengthened , the basic prevention knowledge should be made universal for middle-aged and old people , the health education of key prevention knowledge should be strengthened for the middle-aged and young people , the public health services should be made more open and equal further promoted, and the community comprehensive intervention focusing on the health education should be strengthened.

Ascending and descending efferent projections of superior coUiculus were indentified by means of the anterograde horseradish peroxidase technique in the cat.Following injections of HRP into the rostral superior colliculus, a large number of labeled terminals were found mainly in several of the ipsilateral thalamic nuclei:ventromedial division of the ventral nucleus of the lateral geniculate body, zona incerta,lateral posterior nucleus, parafasciculus nucleus and centromedian nucleus. The mediodorsal nucleus and thalamic reticular nucleus were also found mildly labeled.Labeling were most heavily concentrated in the ipsilateral dorsolateral division of pontine nucleus and caudal region of parabigeminal nucleus. The dorsal part of medial accessory olivary was the only nucleus labeled contralaterally. After injecting HRP into the caudal superior colliculus, only the dorsolateral division of pontine nucleus was densely labeled, while labeled terminals of caudal parabigeminal nucleus signifcantly reduced in amount. No labeled terminals were found in the thalamus as well as medial accessory olivary nucleus. These results indicate that the efferent connections of superior colliculus are topographically organized.

The different distributions of substance P(SP)-and leucine-enkephalin (L-ENK)-like immunoreactive neurons in the midbrain raphe nuclei of the rats have been studied, using PAP immunocytochemical technique. The results showed four main points: 1. SP-containing immunoreactive cell bodies were only seen in the most caudal part of the dorsal raphe nucleus, the average number of SP-positive cell bodies was about 167 in each animal. The L-ENK-like immunoreactive positive cell bodies were found almost in the whole length of the dorsal raphe nucleus, the L-ENK-positive cell bodies were about 132 in each animal. 2. L-ENK-Iike immunoreactive perikarya were mainly located in the midline area of the dorsal raphe nucleus. Besides the above areas, SP-containing immunoreactive cell bodies were also located bilaterally in the extended area from the raphe. 3. L-ENK-containing immunoreactive cell bodies constantly appeared in the median raphe nuclei, the average number was about 199 in each animal, but SP-containing immunoreactive bodies were only observed in this nucleus of two rats. 4. Some SP-like immunoreactive cell bodies or processes were observed in the vincinty of vascular walls, but the L-ENK positive neurons were not found similar results. The present experiment showed that the SP-like immunoreactive perikarya is located in the median raphe nuclei of the rat.

The topographical projection between the parabigeminal nucleus and the superiorcolliculus in the cat was investigated by retrograde and anterograde HRP tracingtechnique.Following HRP injection in the rostral superior colliculus,the labeledsomata were found predominantly in the rostral region of contralateral parabigeminalnucleus,but labeled terminals were heavily distributed in the ipsilateral parabigeminalnucleus,mainly in the caudal region.Following injection of HRP into caudal superiorcolliculus,the labeled somata and terminals were seen in ipsilateral parabigeminalnucleus,chiefly in caudal part,but their number was significantly decreased.It wasnoted that the labeled somata were sparse but labeled terminals were not found inthe parabigeminal nucleus,when the injection was restricted to superficial layers ofsuperior colliculus.After HRP injection into deeper layers of superior colliculus,there existed not only the labeled somata but also the labeled terminals in theparabigeminal nucleus,the former was distributed in bilateral parabigeminal nucleus,the latter in ipsilateral nucleus,chiefly in the caudal part.These results show thatthere are topographical connections between the parabigeminal nucleus and superiorcolliculus,and the parental somata contributing axons to the parabigeminal nucleusare located in deeper layers of the ipsilateral superior colliculus.

Objective: To investigate whether FasL expression by exogenous FasL gene transfer had regulatory effect on drug sensitivity of tumor cells. Methods: Exogenous Fasl, gene transfer was mediated by lipofectAMINE. The FasL expression was detected bv Immunohistochemistry and RT-PCR. The growth inhibition of cytotoxic drugs on tumor cells was measured by MTT assay. Fas mRNA expression was analyzed bv Semi-quantitative RT-PCR. Results: The eukaryotic expression vector, PcDNA3-FasL and PcDNA3 were successfully transteeted into MCF-7 cells. The transfectant cells was named as MCF-7/FL or MCF-7/Vt respectively. FasL was expressed on MCF-7/FL but not on MCF-7/Vt or MCF-7. The cytolysis ot MCF-7/FL induced by adriamycin at concentration of 0.625 ~ 2.5 ?g/ml, cisplatin of 1 .25 ~ 10 ?g/ml, or methotrexate of 3 ~ 6 ?g/ml respectively were all significantly enhanced compared with the cytolysis of MCF-7. Blocking FasL by using F(ab' )2-anti APO-1 antibody markedly reduced this up-regulated cytolysis induced by these drugs The significant up-regulation of Fas mRNA on MCF-7/FL was observed by Semi-quantitative RT-PCR after these drugs treatment. Conclusion: These findings indicated that FasL expression by gene transfer had up-regulation effect on drug sensitivity of tumor cells, this effect was associated with enhanced Fas expression induced by cytotoxic drugs.

Objective To assess the change of left ventricular wall motion at ventricular pacing(VP)by using global circumferential strain (GCS) and segmental circumferential strain of speckle tracking imaging(STI). Methods Seven adult pigs were sedated,followed by median sternotomy and opening of the pericardium. Temporary pacing leads were placed on the right ventricular (RV) epicardium and LV epicardium for RV or LV pacing. A LV short axis view at the mid-level LV was acquired at sinus and VP rhythm. Analysis of circumferential strain by STI was performed offline. The onset of QRS wave was used to characterize the beginning of the cardiac cycle, and the ratio of beginning systolic time, end systolic time and total systolic time to cardiac cycle dyssynchrony was analyzed at sinus and VP rhythm. Results Compared with sinus rhythm,in VP rhythm all of the ratio of the beginning systolic time,end systolic time and total systolic time to cardiac cycle were increased (all P <0.05), and the construction of six segments were dyssynchrony,even segmental paradoxical movement. At VP ≥130 beats/min,both LV global and LV segments sometimes showed irregular motion while the EKG remained normal, which included: ( 1 ) multiple construction and diastole in one heart cycle; (2) A large variability of construction amplitude in several consecutive cardiac cycles. Conclusions VP can lead to several kinds of disturbance of left ventricular wall motion, including delay and lengthening of LV systole, dyssynchrony, and irregularity of systole and diastole.
