Objective Based on the Chinese full version of the Temperament Evaluation of Memphis Pisa Paris and San Diego-Auto questionnaire ( TEMPS-A) , we aimed to validated a short version of TEMPS-A for Chinese adoles-cents.Methods Taking into account the item factor loading from our previously validated full version TEMPS-A, cultur-ally-determined items, and sexual activity related items, we derived a 60-item Chinese TEMPS-A for adolescents.The internal consistency and structural validity of the Chinese TEMPS-A for adolescents was evaluated in 822 participants aged 11~17 years old.Results The Cronbach’ s alphas coefficients for depressive, cyclothymic, hyperthymic, irritable and anxious subscales were 0.67, 0.78, 0.76, 0.77 and 0.83, respectively.The anxious, irritable, hyperthymic factors were effectively distinguished by exploratory factor analysis, while the depressive and cyclothymic factors tended to correlate.The males scored significantly higher on the hyperthymic subscale than the females [(5.407 ±2.842) vs.(4.852 ±2.963), P<0.01].The females scored significantly higher on the depressive [(3.521 ±2.221) vs.(3.144 ±2.295)], cyclothy-mic [(4.484 ±2.922) vs.(3.917 ±2.823)] and anxious [(5.236 ±3.719) vs.(4.366 ±3.658)] temperaments than the males ( P<0.05) .The scores of depressive subscale and cyclothymic temperaments subscale were significantly correla-ted (r=0.625, P<0.001), so did the scores of anxious subscale and irritable temperament subscale (r=0.628, P<0.001).Conclusions The Chinese Adolescent version of TEMPS-A is a reliable and valid instrument for investigating af-fective temperaments for adolescents.

AIM: To observe the changes of the number of NKT cells in spleens and livers of induced model of experimental autoimmune encephalomyelitis (EAE), and to study the role NKT cells play in the immunoregulation of EAE. METHODS: C57BL/6 mice were immunized with MOG<,35-55> peptide and received clinical evaluation daily. The mice were sacrificed at the fastigium and the splenic and hepatic lymphocytes were isolated. The changes of NKT cells in normal and EAE C57BL/6 mice were detected by flow cytometry. RESULTS: The percent of NKT cells in lymphocytes of different organs of EAE model were greater decreased than in that of normal mice. The percent of NKT cells in splenic lymphocytes of normal mice was 2.22± 0.14, while that in EAE mice was 1.94±0.07 (P < 0.05). The percent of NKI cells in hepatic lymphocytes of normal mice was 5.52±2.17, while that in EAE mice was 2.67± 1.41 (P < 0.05). CONCLUSION: The proliferation of splenic and hepatic NKT cells in C57BL/6 mice are inhibited in EAE model, which may indicate that the immune function conducted by NKT cell is down regulated in EAE mice.

Objective:To investigate the effects of GnRH agonist on the expressions of FSHR proteins in pituitary and ovaries in ewes,also to analyse the bioinformatics characteristics of ovine pituitary FSHR.Methods: Forty-two prepubertal ewes (Ovis aries) were randomly assigned to six groups (n=7).The ewes in experimental group EG-Ⅰ,EG-Ⅱand EG-Ⅲwere subcutaneously injected with 200μg,300μg and 400 μg alarelin antigens twice (at day 0 and 14),respectively.Ewes in EG-Ⅳand EG-Ⅴwere injected sub-cutaneously with 200μg and 300μg alarelin antigen four times (at day 0,7,14 and 21),respectively.Ewes in the control group (CG) were subcutaneously injected with 2.0 ml solvent twice (at day 0 and 14).Fluorescence quantitative RT-PCR was used to detect gene expression of FSHR in pituitary glands.The expression of FSHR protein in the ovaries was detected using Western blot.Results:The 2-ΔΔCt values of GnRHR,FSHR and LHR mRNAs in the pituitary gland of EG were lower than that in control group (CG).The 2-ΔΔCt values in EG-Ⅳ( P<0.05 ) and EG-Ⅴ( P<0.05 ) were lower than those in EG-Ⅰand EG-Ⅱ.Expressions of FSHR proteins in EG ovaries increased.Levels of FSHR proteins in EG-Ⅳand EG-Ⅴ( P<0.05 ) were higher than CG.The length of sheep FSHR sequence of nucleotides were 1 091 bp,the homology of FSHR sequences was 100% with that reported in NCBI.The theory isoelectric point , half-life,unstable index,fat index,hydrophobic average were respectively 1.2 h,5.05,47.75,0.836 and 30.61.Conclusion:Alarelin active immunization can inhibit the expression of FSHR mRNA in the pituitary gland ,but increase FSHR expression in ovarian of ewes.FSHR is an unstable hydrophobic protein.

OBJECTIVETo assess the value of (18)F-FDG PET/CT in the diagnosis of solitary nodular-type bronchoalveolar carcinoma (BAC).

METHODSThe clinical and radiographic data were analyzed retrospectively in 30 patients with pathologically confirmed solitary nodular-type BAC who underwent (18)F-FDG PET/CT examinations between August, 2005 and December, 2006. The morphological and radioactive findings of the lesions were reviewed, and the maximum standard uptake values (SUVmax) were measured. The diagnostic accuracy of PET, PET/CT, and HRCT were analyzed.

RESULTSThe (18)F-FDG SUV was markedly lower in BAC than in other well differentiated adenocarcinoma. In 19 of the BAC cases, PET showed a SUVmax of no less than 2.5, demonstrating positive changes. Of the total of 30 cases, 5 had ground glass opacity (GGO) changes, 3 exhibited mixed nodules with GGO changes around the lesions, and 22 cases presented with solid nodules. HRCT showed that BAC located often in the superior lobes of the bilateral lungs, mostly below the pleura in the surrounding lung field; the lesions were patchy or nodular with irregular shapes, showing lobulation in 22 cases, spiculation in 15 cases, pleural indentation in 21 cases, and vacuolar changes in 4 cases. The diagnostic accuracy of PET, PET/CT and HRCT for solitary nodular-type BAC was 36.67%, 93.33%, and 93.33%, respectively.

CONCLUSIONThe SUVmax of BAC provides only limited value for defining the nature of the lesions, but can serve as a general reference for assessing the disease activity. PET/CT, which allows both functional and imaging assessment, can be a valuable modality to reduce the misdiagnosis rate of BAC.

OBJECTIVETo explore the correlation between the HLA-DR13, basic core promoter (BCP), changes of T lymphocyte subset and clinical Chinese medical syndromes of chronic hepatitis B (CHB).

METHODSTotally 102 CHB patients were syndrome typed as Gan depression Pi deficiency syndrome (GDPDS), Pi-Shen yang deficiency syndrome (PSYDS), Gan-gallbladder dampness heat syndrome (GGDHS), Gan-Shen yin deficiency syndrome (GSYDS), and static blood blocking collaterals syndrome (SBBCS). Besides, 30 healthy subjects were recruited as the normal control group. The blood HBV-DNA level and HLA-DR13 gene were detected with real time fluorescent PCR. The expression of CD4+ and CD8+ in T lymphocytes was detected using flow cytometry. The mutation of serum A1762T/G1764A was detected using PCR sequencing. Hepatitis Be antigen (HBeAg) was detected with ELISA, and correlation between various Chinese medical syndrome types and objective indicators were analyzed.

RESULTSThere was no statistical difference in HBV-DNA quantitative results among various syndrome types (P > 0.05). HBeAg positive rate was higher in GDPDS than in other syndrome types (P < 0.05). It was sequenced as GDPDS > GSYDS > SBBCS > GGDHS > PSYDS. Compared with the normal control group, percentages of CD3+ and CD3+ CD4+ were lower in PSYDS (P < 0.05). The ratio of CD3+ CD4+/CD3+ CD8 was lower in GGDHS and PSYDS than in the normal control group (P < 0.05). There was no statistical difference in the CD3+ CD8+ percentage among various syndrome types (P > 0.05). The quantitation of HLA-DR13 gene was lower in GDPDS and GSYDS than in the normal control group (P < 0.05). The positive rate of BCP mutation was higher in GSYDS than in other syndrome types (P < 0.05).

CONCLUSIONCo-detection results of HLA-DR13 and BCP could be used as reference indices of Chinese medical syndrome typing of CHB.
