ObjectiveTo investigate the relationship between novelty seeking and impulsivity behavior in rats.MethodsTwo models were used to test Novelty seeking,one was activity in a new environment model,the other was novel object preference model.And impulsivity was measured by T-maze.All rats(48) were used to examine the relationship between these two behaviour traits.ResultsNovelty seeking:the locomotor activities measured in a new environment for 30 min were (4695.58 ± 1579.87)cm,the exploring number of entries into the novel object area and time spending in the novel object area were respectively(20.92 ± 14.84)entries and (178.12± 135.22)s.Impulsivity:the average times of choosing low reward(LR) in the two test days were(4.71 ±2.71 ).Pearson product moment correlation was performed to investigate the relationship between these two behaviour traits,and the results suggested that there were notable correlation between novel object preference and impulsive decision making( r =0.295,P＜ 0.05 ),yet no significance were found between new environment activity and impulsive decision making.ConclusionNovelty seeking and impulsivity may be correlated with each other depending on different models.

Objective To investigate the expression of KLF4 in cervical carcinoma and its significance. Methods Immunohistochemistry and tissue microarray were used to examine the expression of KLF4 in 39 cases of carcinoma, 30 cases of normal cervical epithelial tissues and 28 cases of cervical cancer in situ. Results Moderate to strong nuclear staining for KLF4 was found in normal tissues and cervical cancer in situ. Interestingly, KLF4 expression was lost in 16 (P<0.05) of 39 carcinoma cases. However, KLF4 expression was not associated with clinicopathologic parameters, including tumor stage and differentiation. Conclusion Our observations indicate that KLF4 may function as a tumor suppressor in the pathogenesis of cervical cancer.

Cefoperazone sulbactam and minocycline were both effec-tive in the treatment of Acinetobacter baumannii intracranial infection. Conclusion:Clinical pharmacists should provide clinical consul-tation for physicians to ensure the safety, effectiveness and economic of patients’ medication.

In recent years,a considerable number of epidemiological investigations and animal studies have confirmed that metabolic diseases, such as obesity,type 2 diabetes mellitus and metabolic syndrome, have adverse effects on brain functions,inducing mood disorders and cognition impairment. Brain dysfunctions induced by obesity and related complications are associated with numerous central abnormalities,involving brain shrinkage and neurotrophic function impairment,brain insulin resistance, brain oxidative stress,and brain leptin resistance,as well as dysfunctioned dopamine motivation and the reward system. Moreover,these brain dysfunctions are mediated by several peripheral factors, such as triglycerides/free fatty acids,proinflammatory cytokines,and corticosterone/glucocorticoid. On the other hand,metabolic disturbances correlated with emotional-cognitive disorders are evident,but the mechanisms remain obscure. Because of the drawbacks of animal models, the majority of researches focus on the impact of mental stress on the metabolism of lipid and glucose. The interrela?tionship between metabolic diseases and brain functions has become one of the hot spots for research. In this review,we mainly discussed the potential mechanisms underlying mood disorders and cognition impairment induced by obesity and related complications.

Objective To investigate the mRNA and protein expressions of nine integrin subunits in human keloid-derived mesenchymal stem cells (KD-MSCs).Methods Cultured KD-MSCs and normal skin-derived MSCs (NS-MSCs) served as the experiment group and control group respectively.Real-time quantitative PCR and Western blot were performed to measure the mRNA and protein expressions of nine integrin subunits in the two groups respectively.Statistical analysis was carried out by t test.Results Real-time quantitative PCR showed no significant difference in the mRNA expression level of any of the integrin units α2,α3,α5,αV,α10,α11 or β1 between KD-MSCs and NS-MSCs (all P ＞ 0.05).The mRNA expression level of integrin α8 was decreased,while that of integrin β3 was significantly increased in KD-MSCs compared with NS-MSCs (both P ＜ 0.01).Western blot revealed that the changes in protein expression levels of integrin units α8 and β3 were consistent with those in their mRNA expression levels in both KDMSCs and NS-MSCs (both P ＜ 0.01).Conclusions Integrin units α8 and β3 may be involved in the occurrence and development of keloid,and the receptors made up of them may play important roles in the pathogenesis of keloid.
