Objective To investigate the influence of unitization encoding strategy and the moderating effect of unitization level on directed forgetting effect of associative recognition. Methods Association recognition paradigm combined with directed forgetting paradigm were employed in this study.The 39 participants acquired by simple random sampling were asked to remember or forget compound words or unrelated word pairs which were randomly presented according to cues.In the retrieval stage, they needed to distinguish " old" or " rearranged" word pairs regardless of the cues. Results (1) The reversed unitization effect reached significance. The discrimination of compound words (0.43±0.03) was lower than that of unrelated words (0.55±0.03) (F=27.27, P<0.001, ηp2=0.42). For the word pairs (to be remembered, TBR), the discrimination of compound words (0.43±0.03) was lower than that of unrelated words (0.59±0.03) (t=-6.05, P<0.001); for the word pairs (to be forgotten, TBF), the discrimination of compound words (0.43±0.03) was still lower than that of unrelated words (0.50±0.04) (t=-2.30, P=0.025). (2) The directed forgetting effect of associative recognition was significant.However, TBR (0.51±0.03) was more discriminative than TBF (0.46±0.03) (F=4.30, P=0.045, ηp2=0.10). But the difference was mainly reflected in the recognition of unrelated words.TBR (0.59±0.03) was more discriminative than TBF (0.50±0.04) (t=3.19, P=0.003). However, there was no significant difference between TBR (0.43±0.03) and TBF (0.43±0.03) in recognition of compound words. Conclusion The unitization encoding stratege can simultaneously promote hit rate and false alarm rate.The directed forgetting effect can be eliminated when unitization level is high enough. Key words: Associative recognition; Directed forgetting; Unitization encoding; Unitization level; Familiarity

Objective To explore the characteristics of event-related potential(ERP) in the development of alert attention of children aged 6-11 years old. Methods A total of 144 children aged 6-11 years old were enrolled in a continuous performance test (CPT, Go/Nogo stimulus task). The latency and amplitude of frontal region cue/uncue-P3 and CNV were analyzed and compared in all age groups. Results (1)Behavioral comparison among different age groups: correct number(35(31, 38), 37(34, 38.25), 37(34.75, 39), 38(35, 39.25), 39(37.25, 40), 39(39, 40)), correct reaction time((566.88±86.63)ms, (530.10±83.40)ms, (509.17±88.99)ms, (488.31±76.23)ms, (463.45±75.78)ms, (417.24±75.78)ms), the differences were statistically significant(P<0.01). (2)Fz lead ERP characteristics: ①Comparison of cue-CNV and uncue-CNV: 6-year-old group((-8.54±4.56)μV vs (-10.13±6.36)μV), 7-year-old group((-9.20±5.34)μV vs (-11.53±4.29)μV), 8-year-old group((-8.37±4.78)μV vs (-11.35±6.38)μV)in amplitude and 9-year-old group((689.25±268.22)ms vs (826.13±174.62)ms)in latency were significantly different(P<0.05). ②Comparison of cue-P3 and uncue-P3: 6-year-old group((4.29±4.11)μV vs (7.45±3.83)μV), 7-year-old group((4.47±4.71)μV vs (5.82±4.40)μV), 8-year-old group((3.76±3.39)μV vs (6.24±4.91)μV), 9-year-old group((4.27±3.57)μV vs (5.93±3.08)μV), 11-year-old group((4.24±4.66)μV vs (6.13±4.42)μV)in amplitude were significantly different(P<0.05). ③Longitudinal comparison among age groups: the latency of cue-CNV in 9-year-old group and 11-year-old group were shorter, and the difference was significant(P<0.05). The amplitudes of cue-CNV and cue-P3 in 10-year-old group were shorter than those in other age groups(P<0.05). Conclusion With the increase of age, the reaction time of school-age children shortened and the correct rate improved.The age of 9-10 may be the high-speed period of the development for brain network on vigilant attention and psychological prediction which may be related to the maturation and development of frontal cortex.

Objective To revised the Taiwan version successful aging inventory (SAI), and verify its reliability and validity in urban elderly in mainland China. Methods SAI was adjusted by culture and revised by pre-test to form a formal questionnaire. A sample of 600 elderly people in Guangzhou was chosen for a face-to-face questionnaire survey through convenient sampling. Half of the sample (n=300) was randomly selected for exploratory factor analysis, and the other was used to confirm the structural validity of SAI. Results Exploratory factor analysis extracted six common factors, including health autonomy, economic security, life adaptation, society and relative relationship, study and family. The cumulative contribution rate of six common factors was 65.366%. The fitting indexes of confirmatory factor analysis were χ2/df=1.861, CFI=0.930, IFI=0.930, TLI=0.923, GFI=0.823, RMSEA=0.054, RMR=0.073. There were significant ceiling effects in the four dimensions of health autonomy, economic security, life adaptation, and family. The internal consistency coefficient (Cronbach's α) of SAI was 0.930, and the test-retest reliability was 0.943. An average score of SAI ≥ 3.95 points was considered successful aging. Conclusion Reliability and validity of SAI are good, which can be used to measure the successful aging status of Chinese elders and track the effectiveness of health promotion measures.

Objective To explore the relationship between gap junction and glucose uptake of astrocytes under oxygen-glucose deprivation(OGD) and reperfusion. Methods Cerebral cortical astrocyte from 1 day newborn SD rats were undergone the primary culture. The ischemia cell model was established by OGD. This experiment were divided into control group, OGD group and OGD+ CBX group.After different reperfusion time (0 h, 12 h 24 h and 48 h), the glucose uptake of astrocyte was measured by 2-NBDG through flow cytometry analysis and connexin 43(Cx43) gap junction plaques was detected using immunofluorescene. Results Compared with the control group, the glucose uptake of astrocyte was up-regulated induced by OGD following different reperfusion time.The glucose uptake of OGD group was (2.32±0.43)nmol/μgDNA in 24 hours reperfusion time and was (0.95±0.28)nmol/μgDNA in control group. The up-regulation was up to 2.63-fold increase (t=13.99, P=0.0024) in 24 hours after reperfusion.Compared with the control group, the Cx43 gap junction number was up to 2.5- fold increase(t=11.34, P=0.003) and the size was 1.85-fold increase (t=10.27, P=0.004) in 24 h reperfusion. The glucose uptake of astrocyte after OGD was reduced by CBX and the decrease was 42% in 48 h after reperfusion. Conclusion Those results urges us consider the clinical treatment for interfering with Cx43 gap junction. Key words: Astrocyte; Connexin 43; Gap junction; Oxygen-glucose deprivation; Glucose uptake

Adhesion G protein-coupled receptors(aGPCRs) play a significant role in cognitive impairment related diseases. As an important member of aGPCRs, brain-specific angiogenesis inhibitor 1(BAI1) has a prominent impact on anti-angiogenesis, anti-tumor and participating in immune phagocytosis. Recent research found out that BAI1 exerts a great influence on synaptogenesis and synaptic plasticity, but few studying concerning BAI1 in nervous system. Nowadays, the aging of population aggravates the occurrence of cognitive impairment. The pathogenesis of Alzheimer's disease and vascular cognitive impairment remains elusive, and identification of cognitive impairment at an early stage faces challenges. In the stage of mild cognitive impairment, synaptic damage is evident. BAI1 can regulate the function of postsynaptic membrane, synaptogenesis, synaptic signal transmission and the morphological development of dendritic spines. Therefore, it may potentially act as an early-warning index and intervention target for cognitive impairment.

Internet gaming disorder (IGD) refers to individuals who are extremely dependent on online games and can’t control the game time reasonably.Generally, individuals with IGD also display withdrawal symptoms when they do not play games.Combined with previous studies, this paper discussed the cognitive dysfunction and neural mechanisms of IGD individuals, including executive function, reward system and emotional regulation dysfunction.First of all, executive function is a high-level cognitive processing ability that involves cognitive and behavioral processes.Cognitive control is often associated with the individual's goal-directed behavior and the ability to flexibly apply the high-level cognitive function. Repeated and excessive game behaviors of IGD individuals may be associated with their abnormal cognitive control and decision-making functions. And the attention process as another important component of executive function. The persistent addictive behavior in individuals with IGD were associated with a bias toward attention to game-related cues.Also, IGD individuals show differences in executive function abnormalities such as decision-making and dominance response inhibition, suggesting that there is a separation between "cold" and "hot" executive function abnormalities, and this feature may also be associated with other cognitive dysfunctions. Secondly, reward incentives play an important role in individual motivational learning and goal-oriented behavior. The increased sensitivity of IGD individuals to reward stimuli in various types of reward and punishment stimuli suggests that their reward system is abnormal.Finally, emotional regulation is an important cognitive function that is closely related to executive function. The anxiety and depression manifested by IGD individuals are often associated with their inability to apply emotional regulation strategies flexibly. It is difficult for individuals with IGD applied emotional regulation strategies flexibly, and inappropriate emotional regulation strategies and emotional responses suggest abnormal mood regulation. To sum up, cognitive dysfunction was not only the basis of IGD addiction symptoms, but also one of the important factors of its symptom maintenance. In addition, the further research prospects included expanded sampling population, deepening neural mechanism research and physical intervention are proposed for the lack of previous research in the last part of the article.

Objective To explore the mediating, direct and indirect roles of self-efficacy, social support and medical coping modes with resilience in patients with chronic hepatitis B. Methods Totally 384 inpatients and outpatients with chronic hepatitis B, without physical ailments or mental problems were selected.The Connor-Davidson resilience scale (CD-RISC), general self-efficacy scale (GSES), medical coping modes questionnaire (MCMQ) and social support rating scale (SSRS) were adopted in this research.The relationship among all variables was explored by path analysis. Results (1)The total scores of resilience, self-efficacy, social support, confrontation, avoidance and acceptance-resignation in chronic hepatitis B patients were (61.64±15.36), (25.40±5.70), (39.82±7.39), (19.02±3.72), (16.63±2.69) and (8.45±2.94), respectively.(2)Pearson analysis showed that the scores of self-efficacy, medical coping and social support were significantly correlated with resilience(r=-0.26-0.82, P<0.05). (3)Importantly, path analysis showed that self-efficacy(β=0.53), confrontation(β=0.10), avoidance(β=0.17) and acceptance-resignation(β=-0.13) had direct prediction effects on resilience.Additionally, self-efficacy was indirectly related to resilience(β=0.05), and social support also indirectly related to resilience through self-efficacy, confrontation and acceptance-resignation(β=0.18). Conclusion Self-efficacy, social support and medical coping are the important factors which play a direct or indirect role in resilience.

Objective To investigate the neuroprotective effect of Ghrelin on traumatic brain injury (TBI) in mice. Methods TBI model of C57BL / 6 mice was established by electronic cortical impact instrument (eCCI). According to the random figure table method, twenty-four mice were randomly divided into sham group(Sham group), TBI group and Ghrelin intervention group(Ghrelin group) with 8 mice in each group. The model of TBI was established in TBI group and Ghrelin group.The mice in Ghrelin group was injected intraperitoneally 0.5 g/kg before and 1 h after injury respectively. And the mice Sham group and TBI group were injected with the same amount of normal saline. The changes of cerebral blood perfusion (CBP) were monitored in real time by laser speckle contrast analysis(LSCI), the changes of neuroelectrophysiology were observed by monitoring motor evoked potential (MEP), and the status of neurological deficit was evaluated by modified neurological deficit score (mNSS). Results Compared with Sham group, the mice in TBI group had significantly lower cerebral blood perfusion(CBP) (t=-12.36, P<0.01), longer latency and lower amplitude of motor evoked potential (MEP) (t=5.03, -11.55, all P<0.01), and significantly higher mNSS scores (t=9.34, P<0.01). However, compared with the TBI group, the cerebral blood perfusion(CBP) of Ghrelin group increased significantly at 12 h after TBI((196.87±17.36) PU/mm2vs (123.62±8.04)PU/mm2, t=10.45, P<0.01), while the latency of MEP decreased((5.30±0.33)ms vs (6.80±0.97)ms, t=-5.01, P<0.01), the amplitude of MEP increased((2.21±0.16)mV vs (1.27±0.27)mV, t=9.65, P<0.01). And compared with the TBI group, the neurological deficit score of Ghrelin group decreased significantly at 24 h after TBI((4.9±1.2) vs (8.4±2.6), t=-3.87, P<0.01). Conclusion Ghrelin exhibits a significant neuroprotective role by increasing cerebral blood flow perfusion, reducing the degree of neurological deficit and promoting motor function recovery in TBI mice.

Objective To identify potential relationship between single uncoding RNA-25-3p (miR-25-3p) expression level and the sertraline efficacy in patients with panic disorder. Methods Sixty cases of patients with panic disorder(case group) and sixty healthy-controls(control group) were collected with demographic data and peripheral venous blood before and after treatment.All the patients were evaluated using the 14-item Hamilton Anxiety Rating Scale (HAMA) and Panic Disorder Severity Scale (PDSS) at baseline, and then received sertraline treatment for 6 weeks.After six-week treatment, each patient was evaluated again with HAMA and PDSS.RT-PCR was used to detect the level of miR-25-3p expression. Results There was no significant difference in the miR-25-3p levels between control group (1.27±0.32) and case group (1.73±1.09) before treatment(t=1.53, P=0.14), but the levels in case group were much higher than that in control group after the treatment (5.72±4.13 vs 1.73±1.09, t=-2.15, P=0.04). Besides, the changes of the miR-25-3p levels were positively related with both the changes of PDSS3 and PDSS7 items before and after the treatment (r=0.60, P=0.02 for PDSS3 and r=0.61, P=0.02 for PDSS7). Conclusions miR-25-3p is associated with the drug efficacy and the outcome of some clinical symptoms of panic disorder.These findings might provide some evidence for the individualized treatment of patients with panic disorder according to regulation of gene expression in the future.
