With the increasing popularity of the Internet and mobile Internet, the Virtual Community （VC） is becoming an important medium for person-to-person communication. To realise the potential of the VC, it is neces- sary to cultivate within it good group cohesion and vitality. Using empirical and experimental research methods, this study explores the ef- fect of users＇ trust in the VC Platform （VCP） on group cohesion and vitality and how brand and perceived privacy security can affect us- ers＇ trust in the VC. The research results indi- cate that the brand of the VCP can directly af- fect users＇ trust in the VC, and can also influe- nce it indirectly through users＇ perceived pri- vacy protection and perceived security protec- tion. Further, this study also confu＇ms that the performance of the VC （group cohesion and vitality） is significantly affected by users＇ trust in the VC. The results of this study can provide theoretical guidance for internet companies to maintain and enhance the value of VCs.

中国脑血管病杂志 2004年第8期1卷 366-371页

The authors described two cases with primitive trigeminal artery. Case 1 was a 32-year-old woman who suffered dizziness and a serious pulsatile intracranial bruit on the left ear, and sometimes associated with pulsatile intracranial bearing-pain on the left temporal side six months before she was admitted to the hospital. She also suffered from obvious diplopia on left lateral gaze for the last 5 months. She had suffered no recent trauma. Magnetic resonance imaging(MRI) demonstrated a suspected intracranial aneurysm located in left cavernous sinus. Digital subtraction angiography (DSA) was performed and a primitive trigeminal artery-cavernous sinus fistula in left side was found. Intraluminal occlusion of the fistula was successfully performed immediately after angiography using 6 Guglielmi detachable coils (GDC), and the patient was cured finally. Case 2 was a 28-year-old woman who suffered a serious intermittent cephalodynia associated with soreness on the left body two years before she was admitted to the hospital. She had suffered no recent trauma. Magnetic resonance angiography(MRA) demonstrated a suspected intracavernous aneurysm of the right internal carotid artery, Digital subtraction angiography (DSA) was performed. Right internal carotid angiography showed a primitive trigeminal artery (PTA) run between the cavernous segment of the internal carotid artery and the distal portion of the basilar artery. On initiation of PTA of R-ICA a small wide-necked saccular aneurysm was incidentally visualized. The aneurysm was successfully embolized after angiography using 2 Stent (Neuroform, 4.5mmm × 20mmm)-assisted detachable coils (Matrix), the ICA and PTA were preserved, and the patient was cured finally.
