Cell bodies of the hypothalamus which project to various subdivisions of theparamedian midbrain were studied in the rat with the method of retrograde axonaltransport of HRP.After small amount of HRP was delivered electrophoreticallyinto the dorsolateral part of the central grey substance,the HRP-labelled cells werefound in the anterior hypothalamic nucleus,the ventromedial nucleus,the dorsome-dial nucleus,the dorsal premammillary nucleus,the ventral premammillary nucleus,the medial mammilary nucleus and the lateral mammillary nucleus,mainly in theipsilateral side.Following introduction of the enzyme into the ventral part ofcentral grey substance,there were HRP-labelled cells in the ipsilateral preoptic area,the lateral area of anterior hypothalamus(dorsal to the supraoptic nucleus),thelateral area of tuberal part,the ventromedial nucleus,the dorsomedial nucleus andthe dorsal premammillary nucleus.By introducing the HRP into the medial part oftegmentum,the HRP-labelled cells were observed in the preoptic area,the lateralarea of anterior hypothalamus,the ventromedial nucleus,the dorsomedial nucleus,the dorsal premammillary nucleus,the medial mammillary nucleus and the lateralmammillary nucleus.

Objective To explore the addictive tendency of internet and its influence factors among adolescents in Longhua District of Shenzhen. Methods A total of 6552 Students were selected from Longhua District of Shenzhen us?ing randomly stratified cluster sampling method. They were inquired about their gender, grade, family type, behaviors of surfing internet, risk behaviors, and internet addiction tendency with a self-report structured questionnaire and the adoles?cent pathological internet use scale (APIUS). Results The prevalence of addictive tendency of internet was 9.0%(590/6552) among adolescents in Longhua District of Shenzhen. Multiple logistic regression analysis indicated that the addic?tive tendency of internet was significantly and positively associated with male (OR=1.32, P<0.05), living in Minzhi area (OR=1.66, P<0.01), secondary school stage (OR=1.62, P<0.01), uncomplete family type (OR=1.49, P<0.01), surfing in cy?bercafé frequently (OR=2.00, P<0.01), compared with surfing 0~2 h/d, surfing 2~4 h/d (OR=1.92,P<0.01), 4~5 h/d (OR=2.97, P<0.01) or more than 6 h/d (OR=4.90, P<0.01), playing games (OR=3.27, P<0.01), chatting (OR=2.80, P<0.01) or having other kinds of entertaining (OR=2.80, P<0.01), and having risky behaviors (OR=2.39, P<0.01). Conclusion The addictive tendency of internet is affected by multiple factors among adolescents in Longhua District of Shenzhen. There?fore, comprehensive intervention measures shall be used to regulate adolescents habits of using internet and prevent them from the internet addiction.
