Objective: The Behavior Preference for Network Game Questionnaire (BPNGQ) was developed. The aim of this study was to provide a measurement for cyberpsychology. Methods: Through interview to players, we formed the pretest of BPNGQ. Then 422 players did the pretest, and 324 players did Internet Addiction Inventory (IAI) at the same time. Results: The item difficulties of all items ranged from 0.2 to 0.7. The discriminations of 70.18% items were good. Factor analyses divided scales into five factors, which were energy of devotion, emotion of devotion, behavior of aggression, emotion of aggression and attitude of aggression. The reliabilities of the subscales and full scale ranged from 0.70 to 0.92. The scores of subscales were significantly positively related with Internet addiction. Conclusion: BPNGQ’s difficulty is appropriate, and it has good discrimination, reliability and validity.

Objective:This research mainly concerns the relationship between the behavior preference in network game and the trait of personality of players.Methods:This study surveyed 294 players by Behavior Preference in Network Game Questionnaire(BPNGQ) and Eysenck Personality Questionnaire(EPQ).Results:All scores in factors of BPNGQ ex-cluding emotion of agression had significant correlations with all dimensions of EPQ.In all traits of personality,there was significant differences between types of killer and relaxing,and no significant difference between catharsis and relaxing.Sanguineous players had lower scores in putting in energy and emotion of devotion.Bilious players had higher scores in behavior of aggression,and players of viscous had higher scores in attitude of aggression.Conclusion:Theory of behavior preference in network game has evidence of personality.Players of different personality traits display various preference in network game.

After the HRP solution was injected into gastric wall of the Beijing Duck, the afferent neurons of the stomach were retrogradely traced. The results arc as follows: 1.The afferent sympathetic neurons from the proventriculus distribute in T_1-L_1 spinal ganglia, concentrically in T_(1-6), the peak number is in T_3. 2.The afferent neurons of the vagus from the proventriculus arc present in the nodosal and jugular ganglia. After HRP was injected into the ventral muscle of the proventriculus, most of the labelled neurons were found in the jugular ganglia. 3.From the gizzard, the afferent sympathetic neurons localize in T_1-L_1 spinal ganglia. The muscle tenium craniodorsalis is concentrated in T,_6, the peak number in T_3. The remained parts of the gizzard are concentrated in T_(2-6), the peak number in T_4. 4.The afferent neurons were retrogradely traced in the nodosal ganglia after HRP was injected into each part of the ventricul. But in the jugular ganglia labelled cells were found only in the region of the muscle tenuim craniodorsalis of the gizzard.

Hyperglycemia is considered to be a predictor of death, poor functional outcome, symptomatic intracerebral hemorrhage, and increased infarct volume in patients with acute ischemic stroke. Many studies have used parameters such as standard deviation, coefficient of variation, blood glucose level, stress hyperglycemia ratio, and glucose/glycated hemoglobin ratio to express hyperglycemia, and then study the relationship between hyperglycemia and stroke outcome. In patients with stroke receiving intravenous thrombolysis, hyperglycemia is closely associated with symptomatic intracerebral hemorrhage, poor neurological outcome, and lower vascular recanalization rate. In patients with stroke undergoing endovascular mechanical thrombectomy, hyperglycemia is closely associated with poor long-term outcome, increased mortality, and increased infarct volume. However, whether hyperglycemia will affect the effect of reperfusion therapy in acute ischemic stroke remains controversial. The possible mechanisms of hyperglycemia leading to poor outcomes after reperfusion therapy in patients with ischemic stroke include inhibition of vasodilation, reduction of plasma fibrinolytic activity, destruction of the blood-brain barrier, promotion of oxidative stress, and reduction of ischemic penumbra volume. Studies have shown that for stroke patients with hyperglycemia, intensive blood glucose control does not bring significant benefits. Therefore, the blood glucose control program of patients with acute ischemic stroke and hyperglycemia needs further study and discussion.

To illustrate the kinds of applicator, indication, side effects, long term follow?up results, clinical experience and the latest developments of intracavitary/interstitial brachytherapy (IC/IS?BT),more than 50 research articles concerning IC/IS?BT about cervical cancer were reviewed.

In Africa about 133 million people lived with disabilities which were mainly the sequelae of infectious disease, war or trauma accidents, single organ dysfunction, refractive error and some others. Medical rehabilitation and community-based rehabilitation could only meet 5%~55% of their rehabilitation needs. Weak infrastructure, poverty and lack of funds, negative attitudes and the monotonous human and culture environments restricted the development of rehabilitation medicine in Africa. Chinese model of rehabilitation medicine seemed to be suitable for Africa. Chinese medical teams in Africa could do a lot in admissions of the disabled, improving hardware conditions,training of professionals, developing new technology and expanding the prestige of rehabilitation medicine.

The effects of the destruction of the periaqueductal gray matter(PAG)on the memory-enhancement by intraperitoneal injection of arginine vasopressin(AVP)were observed in rats.Rats with either sham lesions or electrolytic destruction of the bilateral PAG were trained in a shuttle box for active avoidance response(AAR).After the rats met the criterion of 80% correctness,an intraperitoneal injection of 6?g/kg of AVP or 0.2ml of saline was given.Extinction of AAR was assessed in the rats.It was found that AVP markedly retarded the extinction of AAR in rats with sham lesion,and the extinction of the rats with destroyed PAG was significantly faster than that of the rats with sham lesion.The above mentioned findings suggest that AVP can act on the central nervous system to enhance memory mediated probably through PAG.This observation provides further support for the suggestion that certain limbic midebrain structures are involved in the memory enhancement by AVP.

The role of beta-adrenoceptors in acquisition of learning facilitated by ACTH was observed when the conditioned avoidance response in a shuttle-box was employed as an index of acquisition of learning in rats.The findings were as follows: (1) The conditioned avoidance response increased after behavioral training in a shuttle box was more pronounced in the ACTH group than in the normal saline group (P

BACKGROUND:Exercises play an important role in the recovery of neurological function after stroke. Few studies concerned the amount of exercise in rats after stroke. Hippocampus is strongly associated with cognitive function, but no reports addressed the expression of repulsive guidance molecule A in the rat hippocampus after ischemia and reperfusion. OBJECTIVE:To explore the effects of exercise on repulsive guidance molecule A expression in the hippocampus on the ischemic side in rats after cerebral ischemia-reperfusion injury. METHODS:120 Sprague-Dawley rats were equal y and randomly divided into normal group, sham-operation group, and 7-, 14-, 28-day model groups. The model of right cerebral ischemia-reperfusion injury was induced by ligation with nylon monofilament in rats of 7-, 14-, 28-day model groups. Low exercise group received treadmil training of 5 m/min, 5 minutes;7 m/min, 5 minutes;9 m/min, 20 minutes. Moderate exercise group received treadmil training of 8 m/min, 5 minutes;10 m/min, 5 minutes;13 m/min, 20 minutes. High exercise group received treadmil training of 8 m/min, 5 minutes;11 m/min, 5 minutes;20 m/min, 20 minutes. RESULTS AND CONCLUSION:Repulsive guidance molecule A mRNA and protein expression was highest in the ischemic side of the hippocampus in the 7-day model group without excercise. Moreover, repulsive guidance molecule A relative expression gradual y reduced over time. Compared with non-exercise, repulsive guidance molecule A mRNA and protein expression significantly decreased in the 14-and 28-day model groups during moderate exercise (P<0.05), but repulsive guidance molecule A mRNA and protein expression increased during high exercise. Above data confirmed that moderate exercises could decrease repulsive guidance molecule A expression in the affected side of the hippocampus of rats with cerebral ischemia-reperfusion injury.

Objective To investigate the difference of the morbidity rate of hypertension among patients with sleep apnea syndrome (SAS) in different stages, and the change in the blood levels of some vasoactive substances and their correlations with severity of SAS, in order to further explore the mechanism of hypertension caused by SAS. Methods 63 patients suspected to suffer from SAS were enrolled, and they were divided into normal, mild, moderate, and severe SAS groups according to respiratory disorder index (RDI) obtained by polysomnography (PSG) monitoring. The diagnosis of hypertension was made by the measurement of blood pressure and 24-hour dynamic measurement of blood pressure. Blood levels of angiotesnin Ⅱ (Ang Ⅱ), endothelin-1 (ET-1), throboxane B2 (TXB2), calcium gene related protein (CGRP), 6-keto-protagladin factor1?(6-keto-PGF1?) were determined with radioimmunoassay. Results The mobidity rate of hypertension was significantly higher in moderate and severe SAS group than that in the normal group (P0.05). Correlative analysis showed that the blood levels of Ang Ⅱ, ET-1, TXB2 were positively correlative to RDI (r=0.594, 0.523, 0.574, respectively, P0.05). Conclusion SAS is significantly related to the incidence of hypertension. Vasoactive substances with vasoconstrictive effect such as Ang Ⅱ, ET-1, TXB2 play an important role in the pathogenesis and development of hypertension in SAS patients than those with vasodilative effect such as CGRP and 6-keto-PGF1?.
