Objective: To investigate the relationship among personality traits,motive of Internet use and tendency of Internet Addiction.Methods: Scale of Internet use,NEO-PI-R and Chinese Internet Addiction Scale(CIAS) were administrated to 207 university and high school students.Results: ①Tendency of Internet addiction was significantly correlated positively with openness(O)and agreeableness(A),and negatively with neuroticism(N).②Tendency of Internet addiction showed significant difference among motive of entertainment,study,information and intercommunication,and those who had higher tendency of Internet addiction would have stronger motive.③Internet addiction could be validly predicted by motive of information,entertainment and personality traits of neuroticism(N).Conclusion: Tendency of Internet addiction is affected by personality traits and motive of Internet use.

Balloon tamponade hemostasis has been applicated for 50 years,and its appropriate usage can obtain exact curative effect with less adverse reactions.In recent years,with the continuous improvement in surgical therapy,balloon tamponade technique in treating various types of bleeding has accumulated many successful experiences.This paper intends to review the advances in balloon compression technology for recent years.

It is a consensus to place stent after cutting bile duct in the hepatobiliary surgery in the past.However,as the development of bile physiological research and surgical technique,especially the raise of medical concepts of rapid recovery,the negative effects which are caused by the placement of stent have been taken seriously gradually.Up to now,whether the stent should be placed after the bile duct is cut has no definite answer yet.

Objective To evaluate the effect of omeprazole in preventing treatment of hypertensive cerebral hemorrhage with stress ulcer bleeding. Methods A total of 100 patients with hypertensive cerebral hemorrhage were treated with conventional therapy including dehydration, antihypertensive and supporting treatment. The patients were randomly divided into omeprazole group(n=50) and control group( n = 50). The control group received conventional therapyonly, while the omeprazole group received additional omeprazole 40mg, iv, qd, for 14d. Results Omeprazole group stress ulcer 6 eaess(12.0% ) was significantly lower than the control group 12 cases(24.0% );two groups stress ulcer incidence of severity are increasing with the increase of the disease; the mortalities of cerbral hemorrhage were 6.0 % in the omeprazole group and 16.0 % in the control group and the difference had significant meaning(P＞0.05). Conclusion Omeprazole has significant beneficial effect in preventing upper gastrointestinal hemorrhage after hypertensive cerebral hemorrhage.

Long-term outcomes of surgical bile duct injury (BDI) repair are affected by multiple factors, such as surgeon's experience, severity of BDI, pathological changes of the proximal duct, and the manner and timing of surgical repair. However, the timing of BDI repair is still controversial still. In this article, the authors reviewed the correlation of pathophysiologic changes of the proximal duct, repair timing and outcome discussed in English references. It was shown that pathophysiologic changes of the proximal duct are a major contributor to the timing of BDI repair.

Objective To investigate the relationship between the genetic variation of leptin receptor and obesity in Chinese population. Methods Genomic DNA was extracted from 50 obese subjects 〔Body mass index (BMI)≥30 kg/m 2〕 and 50 normal individuals (BMI

ObjectiveTo evaluate the role of laparoscopic ultrasonography (LUS) in laparoscopic ureterolithotomy.MethodsLUS was utilized in laparoscopic ureterolithotomy for 7 cases of ureterolith to locate the ureter and stone.ResultsLUS demonstrated the relationship of the ureter to the adjacent structures and guided the dissection of the ureter in all the 7 patients and precisely localized the position of calculi.The stone could be touched by atraumatic clamps in 5 cases.LUS-demonstrated localizations of the ureter and calculi were verified on laparoscopic ureterotomy in the other 2.The mean operating time for LUS was 14 min (ranging from 9 to 20 min ).ConclusionsLUS is a real adjuvant means for locating the ureter and stone.

0.05).Conclusion Under atherosclerosis conditions,CO_2 pneumoperitoneum has an adverse influence on the blood flow of the common carotid arteries which may be associated with increased intra-bdominal pressure,absorbed CO_2 gas.

[Objective]AIM To explore the differentiation of neural stem cells from rat embryonic spinalcord in the serum free condition culture medium of OECs.[Method]OECs were acquired by dissection ofolfactory nerve ensheathing and cultured for 20 hours,then suspending cells were put intoselective culture medium and cultured in the fibernectin coated plate.The activity of OECs was detected by MTT method on different periods and the best situation was selected out and serum-free cultured.Exudates of OECs was added into neural stem cells of the third generation.The differentiation of neural stem cells were observed under inverted microscope.The neural stemcells cultured were identified by immumofluorescence method.[Result]The activity of OECs was high on the 9~(th) day and the 12~(th) day.The serum free condition culture medium of OECs induced 53% neuralstem cells to differentiate into neuron-like cells and 42% neural stem cells into astrocytes cells.[Conclusion]The activity of OECs on different periods is different.The serum free condition culture medium of OECs can obviously induced neural stem cells to differentiate into mature neuronecells.

[Objective]Tibial plateau fracture may be combined with soft tissue injuries including menisci injuries, but what tibial plateau fractures influence on meniscus healing has never been reported. This study is to observe the influence on menisci healing caused by knee variation when tibial fracture occurred by making animal models.[Method]Lateral tibial plateau fracture models and non-full-thickness laceratin and perforation defect of menisci models were made in 12 New Zealand rabbits, along with control group without fractures. The differences of menisci healing between two groups were observed with morphological and light microscopic observation after 12 weeks.[Result]No menisci repair in avascular portion could be found in both groups, menisci laceration within vascular portion had repaired the fissures in both groups, and hardly been distinguished from normal tissue. Perforation defect in one third of lateral side coulc be partially filled with protein clot in tibial plateau fractures group.[Conclusion]No evidence revealed that fracture could prevent menisci healing when tibial plateau fractures combined with menisci injury, however, defects of menisci may get advantage of filling tissue from fracture. It still need further research whether it is good for menisci healing or not.
