Objective To investigate the expression of pro-inflammatory cytokines in lumbar dorsal root ganglions (DRG) of rats model of high-dose fentanyl induced hyperalgesia. Methods 64 male SD rats were divided into 2 groups (n = 32), fentanyl group and normal saline (NS) group. The rats were injected with fentanyl (60 μg/kg) or NS 4 times in total subcutaneously with a 15-minute interval. Mechanical and thermal nociception were measured via the tail pressure test (tail flick thresholds, TFT) and paw withdrawal test (paw withdrawal latency, PWL) at 1 day before, at 1, 2, 3 and 4 hour and on 1 ~ 7 day after administration. 4 rats were sacrificed and the lumbar DRG were harvested to analyze the expression of PGE2 , IL-1β, IL-6 and TNF-αvia ELISA. Results There were no significant changes of TFT, PWL and the expression of pro-inflammatory cytokines in DRG compared to baseline of rats in NS group. The value of TFT , PWL in fentanyl group were above the baseline at the 1 ~ 4 hour and below the baseline at 1~3 day after fentanyl injections. PGE2 , IL-1β, TNF-α and IL-6 increased on 1,3,5,7 day after fentanyl injections significantly. Conclusions High-dose fentanyl induced significant hyperalgesia and up-regulation of pro-inflammatory cytokines in DRG. The expression pro-inflammatory cytokines peaked later and were more protracted than the change of behavior test and show no direct relationship between the two.

Objective To revise the individual adaptability measure (I-ADAPT-M) developed by Ployhart & Bliese,and analyze the reliability and validity of its application in college freshmen.Methods Revise the I-ADAPT-M,One thousand and seven hundred freshmen were asked to complete the test,one month later,two hundred and seventy-seven freshmen were simple randomly chosen to report their General Life Satisfaction.Then,the data were analysis by SPSS 18.0 and Amos 4.0.Results The exploratory factor analysis showed that,the Chineseversion of the I-ADAPT-M consisted of 23 projects and 4 dimensions (crisis and creativity adaptability,interpersonal adaptability,stress tolerance adaptability,and resistant learning adaptability),which could account for over 45.344％ of total variance.The Cronbacha coefficient of the Chinese-version of the I-ADAPT-M was 0.82.The confirmatory factor analyzed further revealed the structure of four-dimensional scale(x2=708.80,x2/df =3.16,CFI =0.95,NNFI =0.94,RMSEA =0.051,SRMR =0.053).Male had significant high core in crisis and creativity adaptability and resistant learning adaptability than female.Female had significant high core in interpersonal adaptability than male.Colleges-leader had significant high core in 4 dimensions than general students,it suggested that the Chinese-version of the I-ADAPT-M had good discriminant validity.General Life Satisfaction of the subjects had significant positive correlation with crisis and creativity adaptability,stress tolerance adaptability and interpersonal adaptability,had little correlation with resistant learning adaptability.Conclusion The Chinese-version of the I-A-DAPT-M has good reliability and validity to measure the individual adaptability of the freshman.

Objective To investigate the molecular regulatory mechanism of glucagon like peptide 1 (GLP-1) on proliferation, differentiation and apoptosis of human umbilical cord blood endothelial progenitor cells (EPCs). Methods EPCs were isolated from the umbilical cord blood of healthy pregnant women and cultured in 6-hole cell plate at 2×105 density in vitro, transfected with empty vector plasmid (control group), pcDNA3-GLP-1 plasmid (GLP-1 group), pcDNA3-GLP-1plasmid+AMD3100 (GLP-1+AMD3100 group) and simple AMD3100 (AMD3100 group). The pcDNA3-GLP-1 was transfected into EPCs. The 25μmol/L AMD3100 was used to block the SDF-1/CXCR4 signal pathway of EPCs for 1 h. The cell proliferation was determined by MTT method. The mRNA expressions of differentiation and apoptosis related genes PPARγ, C/EBPα and Caspase-3 were investigated by RT-PCR, and Caspase-3 activity was determined by Caspase-3 activity assay kit. Results Compared to control group, AMD3100 inhibitor showed no effects on cell proliferation, differentiation and apoptosis, while over-expression of GLP-1 in EPCs obviously promoted cell proliferation, and differentiation related genes PPARγand C/EBPαmRNA expression, but down-regulated mRNA expression and the activity of Caspase-3 significantly (P＜0.05), indicating that GLP-1 increased proliferation and differentiation of EPCs while decreased cell apoptosis. When the SDF-1/CXCR4 signaling pathway was blocked by AMD3100, over-expression of GLP-1 induced promotion of cell proliferation, and the differentiation was decreased significantly and the apoptosis was significantly increased (P＜0.05). Conclusion These data confirm that GLP-1 might promote EPCs proliferation and differentiation, and inhibit cell apoptosis through the regulation of the SDF-1/CXCR4 signaling pathway.

Objective To investigate the inhibitant effects of parecoxib, a cyclooxygenase-2 (COX-2) inhibitor, in acute fentanyl induced hyperalgesia in rats. Methods (1) Thirty SD rats (n=6 for each group) were subcutaneously injected with fentanyl (40 μg/kg × 4 times with a 15 min-interval) or saline to establish acute fentanyl induced hyperalgesia model, andparecoxib (5, 10 mg/kg) was administrated intraperitoneally in parecoxib group. Mechanical nociceptive thresholds were measured by the tail pressure test every hour during 1~4 hours and once a day during 1~5 days. (2) 24 SD rats (n = 6 foreach group) were subcutaneously injected with fentanyl as above described and randomly administrated intraperitoneally with parecoxib in 10 mg/kg in 15 min before and at the 4th hour and the 1st day after fentanyl injection except rats in the control group, mechanical nociceptive thresholds were measured by the tail pressure test at time points as above described. Results (1)Acute high dose fentanyl injection induced mechanical hyperalgesia and parecoxib (at 5 or 10 mg/kg)inhibited fentanyl induced hyperalgesia in rats. (2)Parecoxib inhibited fentanyl induced hyperalgesia at 15 min before and at the 4th hour after, but not on the 1st day after fentanyl injection. Conclusions This study provides the first evidence that subanalgesia doses of parecoxib had inhibitory effects on acute fentanyl induced hyperalgesia in time-dependent manners in rats.

Objective To evaluate the long-term efficacy and safety of donepezil in treating patients with Alzheimer's disease(AD).Methods Totally 86 patients with AD were randomly divided into control group(n =43)and treatment group(n =43).The control grou,p received conventional therapy with aniracetam,nimoldipine and ginkgo tablet,while the study group was administrated with donepezil(10 mg/d)on the basis of conventional therapy.The improvements of recognitive ability,mental state,activities of daily life were graded by mini-mental state examination (MMSE),Alzheimer's disease assessment scale-cog(ADAS-cog),activity of daily living(ADL)and global deterioration scale(GDS).The scores were compared between the groups before the treatment and 3,6,12,18,24,30,36,42,48,54,60,66 and 72 months after the treatment,respectively.Results The scores of MMSE,ADAS-cog and GDS after 3 months and ADL score after 6 months (t=2.361,-2.198,-1.790,-2.420,P＜0.05 or P＜0.01)were improved in treatment group than in control group with the best effects at 12 months(all P＜0.01)and the scores continued to decrease after 36 months.At 72 months,the score improvements in treatment group were 7.5 for MMSE,20.3 for ADAS-cog,19.5 for ADL,and 1.4 for GDS as compared with control group(all P ＜0.01).In contrast to pretreatment,there were statistically significant differences in the scores of MMSE,ADAS-cog and GDS at 3,6,12,18 and 24 months,and in the score of ADL at 6,12,18,24 and 30 months after treatment(P＜0.05 or P＜0.01).The differences in the scores of ADAS-cog and GDS after 24 months as well as MMSE and ADL after 30 months were not found(P＞0.05)between pre-treatment and post-treatment.Conclusions Donepezil might be long term effective and safe in slowing down the recognitive and overall function deterioration of AD.

AIM: To investigate the expression and function of apoptosis-related protein, Fas, FasL, and Bcl-2 in the pathogenesis of autoimmune thyroiditis. METHODS: Immunohistochemical staining was performed on 20 Hashimoto's thyroiditis (HT), 20 Graves' disease (GD), and 20 thyroid follicular adenoma (TFA, as control). RESULTS: All the cases expressed Fas, mainly on the cell surface and cytoplasm. FasL was found in all except 3 of the TFA. Bcl-2 in 15 of HT, 19 of GD, 17 of TFA. In TFA follicular cells expressed moderate Fas and minimal or absent FasL. In HT, follicles adjacent to infiltrating lymphocytes showed a increased levels of Fas and FasL, but infiltrating lymphocytes exhibited weaker staining of Fas and FasL than thyrocytes. In GD, thyrocytes and lymphocytes showed nearly similar Fas with HT, but rather weaker for FasL than HT. Bcl-2 was nearly similar in GD and TFA, but follicular cells in vicinity of lymphocytes and lymphocytes located in germinal centers of HT tissues exhibited significantly weaker. CONCLUSION: The expression of Fas, FasL and Bcl-2 in Hashimoto's thyroiditis and Graves' disease was nearly similar. Strong FasL expression and weak Bcl-2 expression on the follicles in HT may induce apoptosis. These results provide further proof that the functions of Fas and its ligand and Bcl-2 may play an important part in the pathogenesis of autoimmune thyroid diseases. The lymphocytes do not seem to be directly engaged in the process with their own FasL, but they may provide some cytokines that, in turn, up-regulates Fas and/or FasL leading to apoptosis.
