Objective To investigate the characteristics of attention networks impairment in patients with lesion in the cerebellum.Methods The attention network test was used to compare patients with lesion in the cerebellum(n=28)with normal controls(n=3.1)on the efficiency of three anatomically defined attention networks:alerting,orienting,and executive control. Results The orienting network effect was significantlyworse(Z=-2.309,P＜0.05)in patients with lesion in the cerebellum((36.32±30.58) ms)than in normal controls((54.39±22.17)ms).The executive control network in patients((160.05± 83.25)ms)with lesion in the cerebellinn was worse than those of controls((93.42±37.41)ms,Z= -3.500,P＜0.01).The alerting networks effects was higher in patients((35.14±45.59)ms)than in normal controls((28.81±26.09)ms),without significant difference.The average reaction time was longer in patients than in normal controls,but there was no significant difference.The wrong rate of attention network testwas significantly higher(Z=-2.119,P＜0.05)in patients(6.57%±9.84%)than in normal controls(3.38%±5.42%).Conclusion The patients with lesion in the cerebellum may be selectively impaired of the orienting and executive networks,while the alering network is spared.

Objective: The study has been testing the efficiency of attention networks in Chinese adults. Methods: The study has used "ANT" to examine 76 normal Chinese adults and analysed the effect on alerting, orienting and executive attention. Results: The reaction time across whole ANT is 502-940(706?105)ms, and the correct ratio is 93%-100%(0.97?0.07).The alerting effect is 30?20ms, orienting effect 51?24ms, and conflict effect 106?32ms. Correlation analyses demonstrate no correlation between alerting, orienting, and conflict resolution. Conclusion: ANT produces reliable subject estimates of alerting, orienting and executive attention function.

Objective To study the prospective memory and the severity of the impairment of event- based prospective memory(EBPM)and time-based prospective memory(TBPM)in normally aging adults. Methods We set a neuropsychological battery to measure the education-matched 40 adults and 40 normally aging adults who were given EBPM and TBPM tasks.Results Compared with the young controls(EBPM, 6.25?1.60;TBPM,5.38?0.87),both EBPM(2.50?0.85)and TBPM(4.93?1.07)in the elderly had been impaired,especially EBPM(t = 13.117,P

Objective To explore the pattern of feedback learning deficits in patients with schizophrenia.Methods Twenty-five patients with schizophrenia and 31 controls participated in the study of probabilistic stimulus selection task.The percentage of choose A and avoid B and individual training blocks of reach performance criterion were analyzed.Results There was no significant difference on the percentage ofchoose A between patient group and control group(control group:(66.13±26.31) ％ ; patient group:(63.75±20.57) ％ ; t=0.37,P=0.713).The percentage of avoid B in patient group was significantly lower than that in control group(control group:(62.10±27.10)％;patient group:(49.75±13.68)％; t=2.212,P=0.032).In addition,the training blocks of reach performance criterion in patient group was significantly greater than that in control group (control group:3.23±2.012;patient group:4.64±1.977; t=-2.635,P=0.011).Conclusion The deficits of feedback learning in patients with schizophrenia is largely due to the failure of avoiding negative feedback stimuli.Learning efficiency was lower in patients with schizophrenia than controls.

Objective To investigate the effects of acupuncture at bilateral ST36 (Zusanli) on attention networks in healthy subjects.Methods The attention network test was used to compare the effects of after acupuncture at ST36 with the effects of before acupuncture on the efficiency of three anatomically defined attention networks:alerting,orienting,and executive control in 40 health university students.Results The alerting network effect was significantly higher (t=4.125,P＜0.001) after acupuncture ((45.60±3.49) ms) than before acupuncture ((33.20±2.88) ms).The executive control network efficiency was significantly higher (t=2.638,P＜0.05) after acupuncture ((87.97±4.21) ms) than before acupuncture ((97.67±4.66) ms).The orienting network efficiency was higher after acupuncture than before acupuncture,but there was no significant difference (P＞0.05).The average reaction time was significantly lower (t=4.848,P＜0.001) after acupuncture ((559.13 ± 10.66) ms) than before acupuncture ((590.57±12.80) ms).Conclusions These results suggest that there are selective enhancements of the alerting and executive control networks after acupuncture,while the orienting network is spared.

Background and purpose:The E-cadherin as a pivotal structural protein is important for cellular polarity and maintainance of normal tissue morphology and cellular differentiation. Recently some study investigated the impact of the C/A genetic polymorphism at-160 from the site of the E-cadherin gene promoter on susceptibility in NPC. To evaluate the association of the E-cadherin gene promoter-160 C/A single nucleotide polymorphism (SNP) and nasopharyngeal carcinoma risk in a Chinese population, we designed a hospital-based case-control study. Methods:Subjects included in this study were 303 patients deifnitely diagnosed with NPC, and 318 matched healthy controls. We used TaqMan Probe method for analyzing polymorphism. Results:The A/A genotype was associated with increased risk of NPC after being adjusted for age and gender (adjusted OR=2.09, 95%CI:1.03-4.22, P=0.04). When 2 gender groups were analysed respectively, female group with A/A genotypes showed a higher risk (OR=7.57, 95%CI:1.57-36.47, P=0.012). Besides, among NPC patients compared with males A/A genotype, females with A/A genotype had a signiifcant risk(OR=2.66, 95%CI:1.14-6.20, P=0.024). Conclusion:The A/A genotype of E-cadherin promoter-160 C/A might be genetic risk factor for NPC, especially female patients.

Alveolar soft part sarcoma (ASPS) is a kind of extremely rare malignant soft tissue sarcoma, which was first discovered and defined by American scholars in 1952. Its main manifestation is painless and slow growth mass, and distant metastasis often occurs in lung, bone, brain, liver with poor prognosis. In recent years, with the accumulation of the number of cases and the development of related technology, the diagnosis and treatment of ASPS have been improved greatly. However, the primary intracranial ASPS is still rare, this paper reviews the progress of primary intracranial ASPS, in order to provide help for its clinical diagnosis and treatment.
