Objective To explore the role of intracellular Ca~(2+) in inhibition of axonal outgrowth,which could learn more about the signal transduction mechanism of Nogo-A inhibiting axonal outgrowth. Methods Using laser confocal microscope,intracellular calcium level in cerebellar granule neurons after Nogo-A added in different times was measured and the effect of Nogo-A inhibiting axonal outgrowth when priming nimodipine was observed. Results The concentration of Ca~(2+) increased in 5 minutes after Nogo-A added,and reached to peak in 30 minutes,then decreased gradually,90 minutes later dropped to normal level.When priming with nimodipine,the axonal inhibition by Nogo-A was partly abrogated compared with control.Conclusion Ca~(2+) may participate in the signal transduction of Nogo-A inhibiting axonal outgrowth.

Objective To study the effect of amelogenin (AML)on the migration,adhesion and proliferation of periodontal ligament stem cells (PDLSCs).Methods STRO-1 +PDLSCs were selected by Flow cytometer.The transwell system was used to detect the effect of AML on migration of PDLSCs.Cells attachment assay was used to detect the effect of AML on adhesion of PDLSCs.MTT was used to detect the effect of AML on the proliferation of PDLSCs.Results The results of transwell showed that AML could induce the migration of PDLSCs with positive correlation.Cells attachment assay showed that the adhesion of PDLSCs was effected by AML as well,and the effect was in-creased with the extension of incubation time.Results of MTT showed that AML could promote the proliferation of PDLSCs in a dose depend-ent manner.Conclusion AML could increase the proliferation,adhesion and migration potential of PDLSCs.

Objective To examine the reliability and validity of the meaning in life questionnaire (MLQ) in Chinese sergeants.Methods Convenience sampling was applied to collect data from 574 sergeants.Part of the data randomly selected (n=278) was conducted exploratory factor analysis and the other (n=296) was used in confirmatory factor analysis.The satisfaction with life scale(SWLS),self-rating depression scale (SDS),and selfrating anxiety scale(SAS) were administered to test the criterion-related validity.Results (1) Exploratory factor analysis vertified a 2-factor model which consisted of presence of meaning (MLQ-P) and search for meaning (MLQ-S),and their cumulative contribution rate was 61.02％.The range of factor loading was between 0.62 and 0.85.Confirmatory factor analysis confirmed the hypothesized 2-factor model (x2 =32.82,GFI =0.97,AGFI =0.94,NFI =0.96,CFI =0.98,RMSEA =0.06).(2) The internal consistencies were good for the overall scale (Cronbach's alpha =0.79) and the subscales (Cronbach's alpha =0.80 and 0.78,respectively).(3) MLQ-P score was positively correlated with SWLS (r=0.21,P＜0.01),while negatively correlated with SDS and SAS(r=-0.50,-0.43).MLQ-S had positive correlation with MLQ-P(r=0.31,P＜0.01).(4)Scores of MLQ-p and MLQ-S in sergeants were higher than college students(t=38.13,P＜0.001,t=25.07,P＜0.001).Conclusion The Chinese version of MLQ is reliable and valid for application to Chinese sergeants.

Pancreatic neuroendocrine tumors(pNETs)have a low prevalence,and may be func-tional as secreting biologically active substance or nonfunctional. With the increased understanding of this disease,new technologies are being developed for diagnosis and treatment. However,surgical excision re-mains the primary therapy for localized tumors and the cure rate is not ideal yet. In choosing the appropri-ate therapy for locally advanced/ metastatic pNETs,medical management strategy should be made in a multidisciplinary context. In addition to chemotherapy,there have been significant advances in targeted mo-lecular therapy.

This paper analyzed existing problems,corresponding solutions and research directions of the effectiveness evaluation indexes of coro-nary heart disease health education and proposed that China should build a standard,reasonable and perfect effectiveness evaluation index system of coronary heart disease health education which combines short-term and long-term evaluation indexes and some relevant standard scales, with the purpose of en-hancing the working efficiency of educators and promoting scientization,standardization and normalization of effectiveness evaluation of health education.

Objective To evaluate the possibility, methods and efficiency of simultaneous transcatheter therapy for perimembranous ventricular septal defect(PMVSD) combined with atrial septal defect(ASD).Methods Four patients with PMVSD combined with ASD, including 3 males and 1 female, age ranging from 12 to 26 years; underwent simultaneous attempted transcatheter therapy. The diameters of PMVSD were 3-6 mm and the distances from the defect rim to aortic valve were 2-6 mm by the echocardiography before the precedure. The stretched diameter of ASD was 6-10 mm. PMVSD were occluded using homemade two-disc PMVSD occluder first and the ASD were occluded later on. Results All patients were treated successfully at one time. The diameter of PMVSD were 3.5-10.0 mm, the diameters of occluder was 4-12 mm. The stretched diameter of ASD was 6-10 mm and the occluder diameter was 6-12 mm. No residual shunt was found by the transthoracic echocardiography and left ventriculography after the occluders deployed. No complication occurred. Conclusion Simultaneous transcatheter therapy for PMVSD combined with ASD is feasible, safe and effective.

In order to evaluate the changes in T cell subsets after acute irradiation injury, and investigate the mechanism of deficiency of cellular immunity in acute irradiation syndrome, Balb/c mice were exposed to a single total body irradiation of 5Gy gamma rays from a 60 Co source. On days 10, 28 and 120, the amounts of CD4 + and CD8 + subsets in spleen cells were evaluated by flow cytometry (FCM), and expression of IL 4 gene in ConA stimulated spleen cells was evaluated by reverse transcription linked polymerase chain reaction, in which ?-actin gene was used as an internal control. It was found that after irradiation, the ratio of CD4 + /CD8 + became significantly higher than that of the controls, and then the ratio lowered gradually until day 120. However, it still did not return to the level of the controls. On day 10, expression of IL 4 gene at mRNA level increased significantly. The results indicated that CD8 + subset was more radiosensitive than CD4 + , and the pattern of cytokine seeretion shifted to that of Th2 soon after irradiation.

Objective To explore the expression of discoidin domain receptor 1 (DDR1) in rats with pulmonary fibrosis induced by paraquat (PQ) poisoning, and its relationship with the expression of transforming growth factor-β1 (TGF-β1). Methods 120 Sprague-Dawley (SD) rats were divided into control group and 20, 40, and 80 mg/kg PQ poisoning groups (each n = 30). Pulmonary fibrosis induced by PQ poisoning model was reproduced by one time administration of 20, 40, 80 mg/kg of 20% PQ, and the rats in control group were given 4 mL normal saline. Fifteen rats in control and different doses of PQ groups were sacrificed at 7 days and 21 days after intragastric administration, and lung tissues were collected. Pulmonary fibrosis was observed after hematoxylin-eosin (HE) staining. The immune-histochemical method was used to determine the expressions of DDR1 and TGF-β1. The relationship between the expression of TGF-β1 and DDR1 was analyzed by Pearson correlation analysis. Results The rats in control group were active, and no pathological changes in lung tissue were found. The rats in PQ groups became shortness of breath, bristles, and slow reaction etc. 0.5 hours after intragastric administration. After 7 days, the lung tissue was dark red, hard texture, appearance of yellow soil fiber nodules and obsolete hemorrhage, destruction of alveolar structure. The extent of lung injury increased gradually with the time of poisoning and the increase of PQ dose. It was shown by immune-histochemical staining that the control group had only a small amount of DDR1 and TGF-β1 positive expressions; in PQ groups, there were a large number of DDR1 and TGF-β1 positive expression particles in the alveolar wall, pulmonary interstitial and alveolar cavity. It was displayed by quantitative analysis that compared with the control group, DDR1 and TGF-β1 expressions were significantly increased in 20, 40, 80 mg/kg PQ groups with time- and dose-dependent [DDR1 (integral A value): 0.221±0.014, 0.249±0.021, 0.364±0.016 vs. 0.121±0.036 at 7 days; 0.247±0.025, 0.321±0.015, 0.432±0.027 vs. 0.139±0.021 at 21 days; TGF-β1 (integral A value): 0.230±0.016, 0.265±0.015, 0.339±0.016 vs. 0.129±0.032 at 7 days; 0.248±0.011, 0.295±0.016, 0.399±0.026 vs. 0.119±0.026 at 21 days; all P < 0.05]. It was shown by Pearson correlation analysis that DDR1 expression was positively correlated with TGF-β1 expression with the increase of PQ dose and poisoning time (DDR1 with TGF-β1: r = 0.996, P < 0.000; DDR1 with PQ dose: r = 0.985, P < 0.000; DDR1 with poisoning time: r = 0.989, P < 0.000; TGF-β1 with PQ dose: r = 0.992, P < 0.000; TGF-β1 with poisoning time: r = 0.972, P < 0.000). Conclusions The expression of DDR1 in the lung tissue in PQ poisoning rats showed a time- and dose-dependent change, and it was positively correlated with TGF-β1 expression. DDR1 may be involved in the process of pulmonary fibrosis induced by PQ poisoning.
