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 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.

Purpose:To explore the regularity of lymph node metastasis in thoracic esophageal carcinoma.Methods:From March 2000 to June 2001,100 patients with thoracic esophageal carcinoma underwent radical esophagectomy with three field lymphadenectomy. Dissection was done through a right lateral thoracotomy followed by repositioning and simultaneous laparotomy and neck incision. Results:The hospital mortality rate was 0%.Nodal metastases occurred in 54% (54/100) of patients. The rate of metastasis to neck, mediastinum and abdomen were 31%, 34% and 26%. Cervical nodal metastasis was not correlated with the depth of tumor penetration. There was a higher frequency in nodal metastasis near the bilateral recurrent laryngeal nerves than that in the bilateral supraclavicular region. Conclusions:①Neck, mediastinum and abdomen nodal metastases occurred frequenthy in thoracic esophageal carcinoma. ②Cervical nodal metastasis could occur in early stage of tumor infiltration.③Cervical lymphadenectomy was a very important factor for accurate staging of thoracic esophageal cancer.

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.

The expression of microRNA (miRNA) is closely related to radio-chemosensitivity in glioma stem cells (GSCs).Moreover,the growth of glioma stem cells could be inhibited comprehensively by increasing radio-chemosensitivity and apoptosis,simultaneously with the regulation of a single miRNA,which has been confirmed by some researches.Thereby microRNA is prospective for the adoption as a specific agent in targeted therapy of glioma,so as to increase the radio-chemosensitivity in glioma stem cells.
