Objective The purpose of the present study was to examine the reliability and validity of the Chinese version of the impulsive-premeditated aggression scale (IPAS) in a sample of Chinese adolescents with aggression. Methods 126 adolescents completed the IPAS,Barratt impulsive scale and self-report questionnaires. In order to assess test-retest reliability, the IPAS was re-administered to 30 participants 3 weeks later.Results Item analysis showed that IPAS had satisfactory item discrimination, 6 items were excluded in the later analysis. The internal consistency of the IPAS Cronbach alpha was 0.77 and the test-retest reliability was 0.74.Exploratory factor analysis demonstrated two stable factors of aggression with good internal consistency and construct validity, the value of KMO was 0.646, the χ2 value of Bartlett test was 691.93 ( P <0.001). The confirmatory factor analysis showed that the value of χ2/df,GFI,AGFI,RMSEA were 1.42,0.874,0.837 and 0.058 respectively.The whole scale and the two secondly scales all correlated with BIS-11 and MOAS.Conclusion The results of the current study indicate that the Chinese version of the IPAS is a useful tool to subtyping aggressive behavior among adolescents, but it still need to be modified to apply in China.

Objective To study the effect of estradiol supplementation during the luteal phase on mouse endometrial expression of leukaemia inhibitory factor and pinopodes in controlled ovarian stimulation cycles.Methods Female mice were randomly divided into four groups:group A[controlled ovarian stimulation(COS)group],group B(COS group with progesterone for luteal-phase-support),group C(COS group with progesterone and estradiol for luteal-phase-support),and group D of natural cycle group.Pinopodes were investigated by scanning electronic microscopy(SEM)in the uterine endometrium of pregnant mice on pregnancy days(pa)3-5.LEukaemia inhibitory factor(LIF)protein Was determined by immunohistochemistry in the uterine endometrium of pregnant mice on pd 3-5.Results (1)In groups B,C,and D,there were small developed pinopodes in the endometrial surface of pregnant mouse on day 3;there were large fully developed pinopodes in endometrial surface,which Was smooth with well defined borders resembling a mushroom on day 4.The regressing pinopodes were observed on day 5.In group A,there were small developed pinopodes in endometrial surface of pregnant mouse on day 3.The regressing pinopodes were seen on day 4.(2)In the pregnant mice of groups C and D,the level of LIF protein on days 3-5 ( 138.5±20. 3,143.1±19. 0) was significantly higher than group A ( 103. 2 ± 5.0, P < 0. 05 ), and strong immunostaining of LIF protein was found on day 4 of gestation. In group B, the level of LIF protein on days 3-5 ( 123.5±10. 8)was significantly higher than group A (P <0. 05), but significantly lower than groups C and D ( P <0. 05 ). Strong immunostaining of LIF protein was found on day 4 of gestation. In group A, weak immunostaining of LIF protein peaked on day 3 of gestation. In groups B, C, and D, the level of LIF protein on day 4 was significantly higher than group A on day 3 ( F = 55.76, P < 0. 01 ). Conclusions Estradiol supplementation during the luteal phase can improve the expression of LIF and pinopodes in mouse endometrium in controlled ovarian stimulation cycles and redress the harmful effect on implantation window by COS. Therefore, estradiol supplementation can improve the endometrial receptivity.

Objective To investigate galectin3 on proliferation and migration of esophageal cancer Eca109 cells.Methods A lentiviral vector for over-expression of RNA targeting galectin3 was designed to transfect Eca109 cancer cells following plasmid-mediated transfection manual (Eca109/Gal3 cells).Inverted fluorescence microscope was used to observe the expression of EGFP.The proliferation of Eca109 cells was measured by cell counting Kit-8 assay.Eca109 cells apoptosis was determined by Annexin-V/7-AAD doublestaining.The migration capacity of Eca109 cells was determined in transwell assays.Western blot analysis was used to measure the expression of galectin3 protein.Results Galectin-3 expression was detected in Eca109 cells,with the Galectin3 expression in Eca109/Gal3 cells much more than non-transfected cells (t =14.33,P ＜ 0.05 ; t =10.28,P =0.037).Compared with non-transfected Eca109 cells,proliferation increased significantly in Eca109/Gal3 cells (t =-17.277,P ＜ 0.05 ; t =-13.4,P ＜ 0.05).Galectin3 evidently decreased in Eca109 cell apoptosis (t =3.053,P ＜ 0.05 ; t =5.446,P ＜ 0.05).Transwell migration assay showed that a greater number of Eca109/Gal3 cells crossed the artificial basement membrane compared with non-transfected Eca109 cells and negative control Eca109 cells (t =3.465,P ＜ 0.05; t =3.252,P ＜ 0.05).Conclusion Galectin3 expression is detected in transfected esophageal cancer Eca109 cells,whose overexpression can result in enhanced proliferation,migration,invasion as well as reduced apoptosis.These data indicate that in-depth research of galectin-3 may prove to be a potential molecular target for the treatment of esophageal cancer.

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Dazhui" (GV 14) on Wnt-β-catenin signal pathway in annulus fibrosus cells in intervertebral disc in rats with cervical spondylosis.

METHODSForty SD rats were randomized into a control group, a model group, an EA group and a medication group, 10 rats in each one. Rats in the control group were treated with sham operation, only incision on local skin; rats in the remaining groups were made into cervical spondylosis models. After model establishment, rats in the control group and model group received fixed treatment under identical condition; rats in the EA group were treated with EA at "Dazhui" (GV 14), 30 min per treatment; rats in the medication group were treated with intragastric administration of meloxicam tablets. Treatments were both given once a day, and 14 days were taken as one session; there was an interval of 2 days between two sessions, and totally two sessions were given. After the treatments, immunohistochemistry was applied to measure the expression of Wnt, glycogen synthase kinase-3β (GSK-3β) and Axin in annulus fibrosus cells; western blot was used to test the expression of P-β-catenin.

RESULTSIn the control group, there were more positive cells of Wnt, GSK-3β and Axin, which were intensively distributed, deeply colored, and strongly positive; In the model group, there were less positive cells of Wnt, GSK-3β and Axin, which were sparsely distributed and weakly positive. The expression of Wnt, GSK-3β, Axin and P-β-catenin in the model group was less than that in the control group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin in the EA group and medication group was higher than that in the model group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin was not significantly different between EA group and medication group (all P > 0.05).

CONCLUSIONEA could delay the degeneration of intervertebral disc, which may be related to EA inhibiting signal pathway of Wnt-β-catenin.

Objective To investigate the expression of nucleotide-binding oligomerization domain protein 2 (NOD2)in serum of patients with hepatocellular carcinoma (HCC),and to analyse the roles of NOD2 in HCC development and its clinical diagnostic value.Methods This study including 66 patients with HCC in the hospi-tal from March 1,2013 to December 31,2014 and 61 healthy controls.Serum NOD2 levels were determined by enzyme-linked immunosorbent assay (ELISA).Analysis of significance was performed with rank sum test using SPSS statistical 16.0 software.Results Serum levels of NOD2 in HCC patients were 171 pg/ml,significantly higher than that of healthy controls(95 pg/ml,Z =-5.00,P =0.00),and the serum NOD2 levels were correla-ted with clinical stage of HCC (H=56.26,P =0.00).Compared with the serum NOD2 levels in stageⅠ,Ⅱpatients (106 pg/ml)and healthy controls (95 pg/ml),the serum NOD2 level in stage Ⅲ and Ⅳ (220 pg/ml) were significantly increased (χ2 =31.24,P =0.00;χ2 =47.23,P =0.00),but the expression of NOD2 in stageⅠandⅡwere nearly equal to that of the healthy controls (χ2 =0.36,P =0.83).The ROC analysis revealed that the best diagnostic cutoff-point of serum NOD2 levels for predicting the Ⅲ and Ⅳ stages of HCC was 148.78 pg/ml,meanwhile corresponding sensitivity was 89.1% and specificity was 77.0%.Additionally,corre-lation analysis demonstrated that there was no significant correlation between NOD2 and alpha-fetal protein (r =0.44,P =0.14).Survival curves obtained that the survival time of HCC patients with NOD2 serum concentrations≥ 200 pg/ml was significantly less than that <200 pg/ml (χ2 =15.32,P <0.05).Conclusion NOD2 is highly expressed in the serum of HCC patients,especially in advanced patients,which is possibly involved in the development of HCC and has the potential to become an effective marker used for HCC diagnosis.

AIM:To explore the protective effect of ischemic preconditioning on myocardial capillary bed. METHODS: Anesthetized open-chest dogs in ischemic preconditioning (IP) group ( n =6) were subjected to 5 min ischemia and 5 min reperfusion for 4 times in left descending coronary artery (LDA) while the dogs in sham-operated (SO) group ( n =6) were observed for 40 min without any stimulating. Myocardial contrast echocardiography (MCE) was performed before the surgery, at the end of the first and the fourth ischemia and reperfusion period, respectively. Myocardial samples in ischemic area were obtained for capillaries ultrastructure examination and their quantitative analysis was conducted by corresponding imagine analyzing system, then compared within group and between control group. RESULTS: (1) Comparing fourth 5 min ischemia with first one, the percents of area defect in minimum (AD min%) by MCE decreased from 32.6%?5.7% to 21.8%?5.2%( P

AIM: To investigate the changes of the redox status and the antioxidative capability in the tissue of malignant tumors. METHODS: The carcinoma tissues collected from 42 patients with primary cancer in digestive tract (13 cases of esophageal cancer, 14 cases of gastric cancer and 15 cases of colorectal cancer),the corresponding paratumor mucosa tissues were taken as the control samples. The content of oxidized and reduced glutathion (GSSG and GSH), oxidized and reduced coenzyme II (NADP+ and NADPH) were measured, the GSH/GSSG, NADPH/NADP+ ratios, and the GSH/GSSG, NADPH/NADP+ redox potentials were calculated according to Nernst formula. RESULTS: The levels of GSH and NADPH in cancer tissues were significantly higher than those in corresponding paratumor tissues (P0.05). CONCLUSIONS: The significant increase in GSH and NADPH contents in cancer tissues indicates a notable enhancement of its antioxidative capability compared with the corresponding paratumor tissues. Based on this changes, the redox potential in the cancer tissues has only slightly reductive shift, which may suggest an apparent oxidative stress existed in the cancer tissues.
