Objective: To explore the Asian Resilience Scale’s preliminary revision, reliability and validity in college students of China. Methods: 646 students were investigated with the Asian Resilience Scale and the short form of NEO Five-Factor Inventory. Results: ①Three factors were extracted by exploratory factor analysis and explained 47.1% of variance. ②Confirmatory factor analysis showed good fit between the data and the construct of scale, ?2/df=2.36,RMSEA= 0.055,GFI=0.923,CFI=0.908,NNFI (TLI)=0.894. ③The Cronbach’s ? coefficients, split-half and retest reliability of the total scores were 0.865, 0.836 and 0.894 respectively. ④The total score of the Asian Resilience Scale was significantly negatively correlated with neuroticism and positively correlated with extraversion, openness to experience, agreeableness and conscientiousness. Conclusion: Reliability and validity of the Asian Resilience Scale’s revised Chinese version is corresponded with psychometric standard, and it could be used to assess the resilience of Chinese college students.

BACKGROUND: Studies have confirmed that umbilical cord blood stem cells can improve the neurologicalfunction after stroke, but the mechanism of umbilical cord blood stem cells in the treatment of stroke is unclear.OBJECTIVE: To review the effect and mechanism of umbilical cord blood stem cells in the treatment of stroke.METHODS: The first author searched PubMed and CNKI databases for relevant articles published from January2005 to December 2015 using key words of umbilical cord blood stem cells, stroke in English and Chinese,respectively. RESULTS AND CONCLUSION: With the further research on the neural differentiation of umbilical cord blood stem cells,umbilical cord blood stem cells have become a hot research topic in the field of neural system disease therapy. Atpresent, some experimental studies on cell transplantation for stroke have achieved ideal curative effects. However, themechanism of umbilical cord blood stem cells in the treatment of stroke is not clear. Known therapeutic mechanismsinclude the recombination of blood vessels, nerve loops and other damage tissue structures, secretion of variousnutritional factors to reduce endogenous apoptosis, promotion of endogenous blood vessels and nerve regeneration, etc.But the following problems need to be further studied, including whether the transplanted cells can be fully filled toreplace necrotic nerve cells and promote recovery of nerve function; how these survived stem cells establish the neuralconnections; how these transplanted cells reduce the apoptosis and necrosis of the host cells to restore the cell function.

Objective To investigate the clinical importance and the relationship between the levels of plasma total homocysteine (Hcy), serum folic acid and vitamin B 12 , and the occurrence and development of ischemic leukoaraeosis (LA). Methods Ischemic LA group and normal control group with 100 cases for each were studied. The 100 cases in ischemic LA group were firmly diagnosed by CT or / and MRI. The levels of plasma total Hcy, serum folic acid and vitamin B 12 of the patients in ischemic LA group were measured, and compared with that in control group. Results The level of plasma Hcy in ischemic LA group (19.79?5.25?mol/L) was significantly higher than that in control group (12.02?2.11?mol/L), while the levels of serum folic acid and vitamin B 12 in ischemic LA group (2.08?0.84ng/ml and 140.13?45.49pg/ml) were lower than that in control group (4.39?1.30ng/ml, 297.45?120.23pg/ml). The differences between two groups were statistically significant (P

AIM: To explore the protein levels of chemokine receptor 7 (CCR7) and vascular endothelial growth factor ( VEGF)-C in breast carcinoma , and to investigate the effects of CCR 7 and VEGF-C on prognosis of breast carcinoma.METHODS:The protein expression levels of CCR 7 and VEGF-C in the breast carcinoma tissues and normal breast tissues were detected by the method of immunohistochemistry .At the same time, the relationship between clinico-pathologic characteristics and the protein expression of CCR 7 and VEGF-C in the breast carcinoma tissues was analyzed . The relationship between the protein expression of CCR 7 and VEGF-C and survival time of the breast cancer patients was estimated by Kaplan-Meier method.RESULTS:The positive expression rates of CCR 7 and VEGF-C in the breast carcino-ma tissues were significantly higher than those in the normal breast tissues (P<0.01).A positive correlation was observed between the protein expression of CCR7 and the protein expression of VEGF-C in the breast carcinoma tissues (r=0.613, P<0.01).The protein expression of CCR7 and VEGF-C was correlated with lymph node metastasis and TNM stage (P<0.05), but both were not related to patients ’ age, primary tumor size, estrogen receptor and progesterone receptor .The survival time of the patients with CCR 7 and VEGF-C positive expression was significantly shorter than that of the patients without the expression (P<0.05).CONCLUSION:The positive expression of CCR7 and VEGF-C proteins is associated with the prognosis of breast cancer , and combined detection of CCR 7 and VEGF-C protein expression levels may be helpful to judge the prognosis of breast cancer .

Objective To investigate effect of laparoscope anesthesia inducted by sevoflurane combined with different doses of propofol on vascular endothelial growth factor-C (VEGF-C) and prostaglandin E2(PGE2)in patients with hysteromyoma.Methods 77 cases of patients with uterine fibroids were selected and divided into two groups.40 cases in group A were anesthetized inducted by 2.0 mg/kg propofol combined with sevoflurane, 37cases in group A were anesthesia inducted by 1.0 mg/kg propofol combined with sevoflurane.VEGF-C and PGE2 in serum were compared before and 48h after the operation.Results Compared with preoperation, VEGF-C and PGE2in serum were lower (P<0.05), VAS score was lower (P<0.05);Compared with group B, VEGF-C and PGE2 in serum of the group A were lower (P<0.05), VAS score was higher (P<0.05).Conclusion Different doses of propofol on serum VEGF-C and PGE2 in patients with laparoscopic uterine fibroids have different effects, 1.0 mg/kg has a sedative effect, 2 0 mg/kg with anesthesia induction.
