OBJECTIVETo study the effect of cesarean section birth based on different indications on attentiveness in school children.

METHODSA total of 308 school children were assigned to three groups according to their birth model: natural delivery (n = 105), cesarean section due to social factors (n = 101) or medical factors (n = 102). The integrated visual and auditory continuous performance test (IVA-CPT) was performed for assessing attentiveness.

RESULTSThe IVA-CPT demonstrated that there were significant differences in the quotients of combination control, auditory response control, combination attention, auditory attention, visual attention, auditory vigilance, visual concordance, visual vigilance and visual attention among the three groups (p<0.05). The results of the IVA-CPT in the group of cesarean section due to medical factors was obviously poorer than that of the natural delivery group and the group of cesarean section due to social factors. However no significant differences were observed between the groups of natural delivery and of cesarean section due to social factors.

CONCLUSIONSCesarean section itself has no significant impacts on attentiveness in school children, while medical indications for cesarean section may contribute to major cause of attention deficit disorder.

OBJECTIVETo study the incidences of comorbidities and behavioral problems in children with functional articulation disorders.

METHODSOne hundred and twelve children with functional articulation disorders (aged 4-11 years) were enrolled. Their comorbidities were identified based on clinical investigations and the DSM-IV diagnosis criteria of attention deficit hyperactivity disorder (ADHD), stuttering, tic disorders and enuresis. Behavioral problems were evaluated by the Conners Parent Symptom Questionnaire and the Child Behavior Checklist.

RESULTSSixty-nine patients (61.6%) had one or more comorbidities. The incidence of comorbidity in children with middle-severe functional articulation disorders was higher than in those with mild disorders. The most common comorbidity was language impairment (30.4%), followed by stuttering (16.1%), enuresis (13.4%), and tic disorders (6.3%). In school age children, ADHD (47.5%) was the most common comorbidity. The incidence of behavioral problems was 40.2% by the Child Behavior Checklist and 57.1% by the Parent Symptom Questionnaire.

CONCLUSIONSThe children with functional articulation disorders have high incidence of comorbidity and many behavioral problems.

Objective:To investigate the mechanism and clinical value of nicotinamide phosphoribosyltransferase(NAMPT)in multiple myeloma(MM).Methods:RT-qPCR and Western blot were used to detect the expression of NAMPT in MM cells and normal bone marrow mononuclear cells.The biological function of NAMPT was analyzed by cell proliferation and apoptosis assay,small interfering RNA silencing,overexpression assay and chromatin immunoprecipitation assay.Results:The mRNA and protein expression levels of NAMPT in MM cell lines(MM1R,MM1S,U266 and RPMI-8226)were significantly higher than those in normal bone marrow mononuclear cells(P＜0.001),and were most obvious in U266 cells.Compared with Si-NC group,the proliferation of U266 cells in Si-NAMPT group was significantly inhibited at 24,48 and 72 h after transfection(P=0.006,P＜0.001,P=0.00 1),and the apoptosis rate of U266 cells was significantly increased at 48 h after transfection(P＜0.00 1).Compared with Flag-NC group,U266 cell proliferation in Flag-NA4MPT group was significantly increased(P=0.003,P=0.002,P＜0.001),while the apoptosis rate decreased significantly at 48 h after transfection.The expression of NAMPT in U266 cells was regulated by XBP1 at transcriptional level.The proliferation rate of U266 cells with XBP1 or NAMPT stable knockout or MKC3946 pretreated with bortezomib was significantly decreased,the levels of BCL-2 mRNA and protein were also significantly decreased,while the levels of BAX mRNA and protein were significantly increased,moreover,the cleavage degree of caspase-3 significantly decreased,while caspase-3/7 activity increased dramatically(P＜0.05).Conclusions:The high expression of NAMPT in MM cell line can promote MM cell proliferation and inhibit apoptosis.NAMPT is regulated by IRE1α-XBP1 signaling pathway in U266 cells.Stable knockdown of NAMPT or blocking of IRE1α-XBP1 pathway can significantly increase the sensitivity of U266 cells to bortezomib.

OBJECTIVETo probe into the mechanism of electroacupuncture intervention for lipid metabolism of metabolic syndrome patients.

METHODSEighty cases of metabolic syndrome were randomly divided into an electroacupuncture combined with western medicine group (observation group) and a simple western medicine group (control group), 40 cases in each group. The observation group was treated with electroacupuncture at Back shu points, Zusanli (ST 36),Zhongwan (CV 12),Sanyinjiao (SP 6) etc. as main combined with oral administration of Simvastatin, Glipizide XL, and Felodipine sustained-release tablets for lipid-lowering, glucose-lowering and antihypertensive treatment; the control group was treated with oral administration of western medicine only (the medicine was the same with observation group). The Body Mass Index (BMI) and the blood lipid of the patients were detected respectively before and after treatment.

RESULTSThe BMI, Three Acids Glyceride (TG), Total Cholesterol(TC), Low Density Lipoprotein Cholesterol (LDL-C) and High Density Lipoprotein Cholesterol (HDL-C) were compared respectively before and after treatment, there were significant differences between them in observation group (all P < 0.01); while in control group, there were significant differences of TG,TC,LDL-C and HDL-C before and after treatment (all P < 0.01), and with no significant difference in BMI before and after treatment. There were significant differences of BMI,TG,TC,LDL-C and HDL-C between two groups after treatment (P < 0.01, P < 0.05).

CONCLUSIONThe electroacupuncture has an obvious effect to reduce body mass, and acupuncture combined with medication has a better effect of improving the lipid metabolism than simple medication.

This study was purposed to explore the changes of possible angiogenetic factors other than VEGF after inhibition of NHE1 and their related mechanisms. The K562 cells were treated by NHE1 specific inhibitor cariporide, the angiogenesis factors after inhibition of NHE1 were screened by using protein chip, the IL-8 expression level after cariporide treatment was detected by real-time quantitative PCR; the K562 cells with stable interference of NHE1 were constructed, the IL-8 expression level after interference of NHE1 was detected by real-time quantitative PCR; the p38 phosphorylation level in K562 cells treated with cariporide was detected by Western blot. After treatment of K562 cells with p38 inhibitor SB203580, the IL-8 expression level was decreased by real-time quantitative PCR. The results of protein chip showed that IL-8 expression decreased after cariporide treatment. Real-time quantitative PCR confirmed this inhibitory effect. The p38 phosphorylation level increased after cariporide treatment. The down-regulation of IL-8 expression induced by cariporide treatment was partially restored after K562 cells were treated with p38 inhibitor SB203580. It is concluded that the inhibition of NHE1 can inhibit IL-8 expression through up-regulation of p38 phosphorylation.
