Objective To investigate current status of preschool children's social competence and its relation to tempera-ment type. Methods A total of 1 251 children participated in this study. The questionnaire was conducted and the children were assessed usinginfant-junior middle school student's ability of social life scaleandchildren's temperament scale. Results No significant gender difference was observed in total score of social competence (P>0.05). The total score of live independently was higher in girls as compared to boys (P<0.05). A significant gender difference was observed in classified scores of social competence (P<0.05). Girls with excellent or better-than-normal social competence were more than boys (P<0.05). The distribu-tion of the temperament type in preschool children were the difficult-to-raise type (8.1%), the start-slow type (15.4%), the stan-dard type (69.0%) and the easy-to-raise type (7.5%). There was statistically gender significance (P<0.05) in the distribution of the temperament types. The percentage of difficult-to-raise type was higher in girls than in boys. The percentage of easy-to-raise type was higher in boys than in girls. The total score and classified scores of social competence had significant difference among children with different temperament types (P<0.05). Conclusions There is significant diffe-rence of social competence in chil-dren with different temperament types. Corresponding educational measures according to the child's temperament may be bene-fit to the development in preschool children.

BACKGROUND:Cytokines and neurotrophic factors secreted from human umbilical cord blood-derived mesenchymal stem cells secrete have neuroprotective effects on cerebral ischemia-reperfusion injury, but there are few reports about intranasal administration of human umbilical cord blood-derived mesenchymal stem cellconditioned medium in the treatment of stroke.
OBJECTIVE:To investigate the protective effects of intranasal administration of human umbilical cord-derived mesenchymal stem cells-conditioned medium on neurologic function of rats with cerebral ischemia-reperfusion injury.
METHODS:Adult rats were subjected to 2 hours of right middle cerebral artery occlusion and the human umbilical cord-derived mesenchymal stem cells were isolated from the postpartum human cord. We made the conditioned medium of human umbilical cord-derived mesenchymal stem cells. Ischemic rats were randomized and assigned to three groups and were treated by intranasal routine starting 24 hours after middle cerebral artery occlusion with:(1) saline for control group;(2) Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12 medium for medium control group;(3) conditioned medium treatment group (10mL/kg) daily for 14 days. Behavioral tests (foot fault test, and modified Neurological Severity Score) were performed before and at 1, 7, 14 days after middle cerebral artery occlusion.
RESULTS AND CONCLUSION:There was no difference in the behavioral tests among the three groups at postoperatively 1 day (P>0.05). Compared to the control and medium control group rats, respectively, rats in the conditioned medium group significantly improved functional outcome after stroke in days 7 and 14 (P<0.05). There was also no significant difference in functional tests between the control group and medium control group in days 7 and 14 (P>0.05). These results suggest that human umbilical cord-derived mesenchymal stem cells-conditioned medium via intranasal administration can significantly improve neurologic functional outcome after cerebral ischemia-reperfusion injury.

BACKGROUND:Large numbers of experimental data have confirmed that bone marrow mesenchymal stem cel s have a positive therapeutic effect on cerebral ischemia-reperfusion injury, but there are few reports about intravenous administration of bone marrow mesenchymal stem cel conditioned medium in the treatment of stroke.
OBJECTIVE:To investigate the effects of the conditioned medium of rat bone marrow mesenchymal stem cel s on the recovery of neurological function in rats after cerebral ischemia-reperfusion injury.
METHODS:The bone marrow mesenchymal stem cel s were isolated from rat bone marrow. When cel s at passage 2 or 3 reached 90%confluence, the original culture medium was removed. Then the cel s were cultured in serum-free DMEM for 18 hours. After that, the culture solution was col ected as the conditioned medium of rat bone marrow mesenchymal stem cel s. Adult rats were subjected to 2 hours of right middle cerebral artery occlusion. Ischemia-reperfusion injury rats were randomly assigned to three groups:control group, simple culture medium group and conditioned medium group, and respectively given injection of normal saline, DMEM, conditioned medium (10 mL/kg) via the tail vein at 2, 24, 48 hours after operation.
RESULTS AND CONCLUSION:There was no difference in the behavioral tests among the three groups at postoperative 2 hours (P>0.05). Compared with the control and simple culture medium group, neurological impairment was significantly improved in the conditioned medium group at postoperative 1, 3, 5 days (P<0.05), but there was no significant difference between the control and simple culture medium groups. At postoperative 5 days, brain edema was significantly eased in the conditioned medium group in comparison to the control and simple culture medium groups (P<0.05), and there was also no difference between the latter two groups (P>0.05). These results suggest that rat bone marrow mesenchymal stem cel s-conditioned medium via intravenous administration can significantly ease brain edema and improve the neurologic function after cerebral ischemia-reperfusion injury.

Purinergic 2X7 receptor (P2X7R) and Nod like receptor pyrin domain containing 3 (NLRP3) inflammasome contribute to the inflammatory activation.Great attention has been paid to P2X7R and NLRP3 inflammasome in recent years,especially in the fields of central nervous system.To further elucidate the role of the P2X7R and NLRP3 inflammasome in the central nervous system,we review the latest research progress of composition and physiological functions of P2X7R and NLRP3 inflammasome and how they play their roles in diseases of the central nervous system.

PURPOSE: This study aimed to evaluate the clinicopathological characteristics of pregnancy-associated breast cancer (PABC) in comparison with non-pregnancy associated breast cancer (non-PABC). METHODS: A total of 344 eligible patients with PABC were identified in the Korean Breast Cancer Society Registry database. PABC was defined as ductal carcinoma in situ, invasive ductal carcinoma, or invasive lobular carcinoma diagnosed during pregnancy or within 1 year after the birth of a child. Patients with non-PABC were selected from the same database using a 1:2 matching method. The matching variables were operation, age, and initial stage. RESULTS: Patients with PABC had significantly lower survival rates than patient with non-PABC (10-year survival rate: PABC, 76.4%; non-PABC, 85.1%; p=0.011). PABC patients had higher histologic grade and were more frequently hormone receptor negative than non-PABC patients. Being overweight (body mass index [BMI], ≥23 kg/m²), early menarche (≤13 years), late age at first childbirth (≥30 years), and a family history of breast cancer were more common in the PABC group than in the non-PABC group. Multivariate analysis showed the following factors to be significantly associated with PABC (vs. non-PABC): early menarche (odds ratio [OR], 2.165; 95% confidence interval [CI], 1.566–2.994; p<0.001), late age at first childbirth (OR, 2.446; 95% CI, 1.722–3.473; p<0.001), and being overweight (OR, 1.389; 95% CI, 1.007–1.917; p=0.045). CONCLUSION: Early menarche, late age at first childbirth, and BMI ≥23 kg/m² were more associated with PABC than non-PABC.

OBJECTIVETo assess the association of neural development-related genes LIS1and TSNAX with bipolar disorder in a Chinese Han population.

METHODSThree hundred and eight five patients (including 188 males and 197 females) from Guangzhou Brain Hospital with bipolar disorder meeting the Diagnostic and Statistic Manual of Bipolar Disorder (BDI) (Fourth Edition) criteria and 475 healthy controls from the local community were recruited. Ten single nucleotide polymorphisms (SNPs) of the LIS1 and TSNAX genes were genotyped by GoldenGate genotyping assay on an Illumina Beadstation 500 machine. Association analyses of SNPs and haplotypes were performed with Plink 1.07 software.

RESULTSAnalysis of the total sample has failed to find any association of SNP or haplotype of the two genes with BDI (P> 0.05). When patients were divided into subgroups with or without psychotic symptom, no significant association of the two genes was found with psychotic BDI or non-psychotic BDI (P> 0.05). No significant association was found between any SNP and haplotype of two genes and female BDI or male BDI, nor were significant association found between age of onset and LIS1 and TSNAX gene polymorphisms.

CONCLUSIONOur results indicated that LIS1 and TSNAX genes are not associated with susceptibility to bipolar I disorder in Chinese Han population.
