Objective: To examine the reliability and validity of self-report scale of brief psychopathological symptoms(SBPS). Methods: The reliability and validity of the scale were tested based on three groups of subjects, including the cases involved forensic problems, the patients with mental disorders and normal persons. Some of them were retested 5-15 days after first examination. Other subjects of them finished MMPI at the same time. Results: ①The Cronbach's ? coefficients of SBPS was 0.91. The split-half reliability was 0.90. The test-retest reliability ranged from 0.73～0.98. ②The correlations between factors scores and the total scores ranged from 0.79 to 0.87. The correlations among the four factors scores, ranged from 0.50 to 0.65. Significant correlation was found between the total scores of SBPS and the fake scores of MMPI (r =0.76). Based on the experts diagnosis, the accuracy rate of SBPS for evaluating malingering was 86.6%. Conclusion: The SBPS has acceptable psychometrics properties on reliability and validity.

Objective:To explore the executive function of neuroleptic -naive and short -term medicated onset schizophrenic patients.Methods:55 drug naive patients and 49 patients with schizophrenia medicated for one month and 60 normal controls were administered the Wisconsin Card Sorting Test(WCST) to study the executive function.Results:Compared with the controls,neuroleptic-naive patients and medicated patients showed higher level in the number of total trials,perseverant errors,random errors,the rate of error responses and the rate of random errors,while they showed lower level in the number of categories,correct trials and the rate of correct responses.There was no significant difference in WCST between the neuroleptic-naive patients and medicated patients.Conclusion:Neuroleptic-naive and short-term medicated onset patients with schizophrenia may have executive dysfunction.

Objective:To observe expression of stathmin gene in laryngeal squamous cell carcinoma(LSCC) and relation between expression of stathmin gene and occurance and development of LSCC.Method:The expression of the stathmin gene was determined in 35 LSCC of specimens and 18 normal laryngeal tissues(NLT) of specimens by in situ hybridizaion with Digoxigenin labled probe of stathmin mRNA.Result:Expression of stathmin gene was observed in 35 cases of laryneal squamous cell carcinoma tissue (positive rate, 69%) and positive signal was observed in both cytoplasm and nuclear. Among 18 cases of normal tissue, only 6 showed weak positive signal. There was significant difference in expression of stathmin gene between laryneal squamous cell carcinoma tissue and nomal tissue.Conclusion:Expreesion of stathmin gene may play a key role in the pathogenisis and development of laryneal squamous cell carcinoma. It may be a very important biotherapy target in the treatment of laryneal squamous cell carcinoma.

Objective To investigate the expression and clinical significance of the estrogen receptor beta isoforms and survivin in thyroid tumors. Methods The pathological data of 125 patients with thyroid tumors were, collected from june 2003 to june 2007 in our institution, including thyroid carcinoma (86 cases), thyroid follicular adenoma (39 cases) and normal thyroid tissue (10cases). SP immunohistochemistry was used to measure the expressions of ERβ and survivin in the thyroid tumors. Results ERβ not only was detected in the thyroid epithelial cell plasma and nuclear, but also in the stroma. The positive rate of ERβ in cases with thyroid carcinoma, adenoma and normal thyroid tissue were 83.72 %, 51.28 % and 20.00 % respectively. There was significant difference between carcinoma and the adenoma or normal thyroid tissue (P<0.05). The positive rate of survivin in cases with carcinoma, adenoma and normal thyroid tissue were 59.30 %, 17.95 % and 0 respectively. There was significant difference between carcinoma and the adenoma or normal thyroid tissue (P<0.05). The expressions of ERβ and survivin correlated with TNM staging and lymph node metastasis of thyroid carcinoma (P<0.05). Conclusion ERβ may play a role in accelerating proliferation in the occurrence of the thyroid carcinoma. The expressions of ERβ and survivin are related to invasion and metastasis of thyroid carcinoma.

Objective To research the expression of the estrogen receptor alpha ( Erα) and estrogen receptor beta ( Erβ) in uvea tissues of the female rats, and to provide molecular biology data for further studies of the relation estrogen to uvea diseases. Methods Twenty-two adolescent SD female rats were selected. All rats were killed by dislocation of cervical vertebra, the eyeballs were in paraffin imbedding and made to a series of sections, using immunohistochemical method;Erα and Erβ distribution were investigated in uvea tissue of rats;and quantitied by Tanaka scores analytical method. The uteri of rats was used as positive control and PBS as negative control. The level of estradiol in serum of the rats were examined by radioimmunoassay. Results The expression level of Erβ was moderate or highter in stroma cell, anterior pigment epithelium as well as pasterior pigment epithelium of the iris, unpigmented epithelium, pigmented ciliary epithelium and vascular endocemet of the choroid layers. But Erα was not obviously expressed in uvea tissues. The expression rate of Erβ was higher than Erα in these tissues(P＜0.05). Immnoreactivity positive substance was granule, which was distributed in the cytoplasm or in the nucleus. The level of estradiol in serum of the rats was (22.13±3.54)ng/L.Conclusion The expression of either Erα or Erβ in uvea tissues of rats is mainly in Erβ. The results indicate that uvea tissue is regulated directly by estrogen throught Erβ.

Purpose:To study the role of DCs in tumor infiltrating T lymphocytes activation of esophageal carcinomas.Methods:46 specimens of patients with esophageal carcinoma were used to investigate the DCs (CD1a), the subsets of tumor infiltrating T lymphoctyes (CD3,CD4,CD8, CD25) and costimulatory B7 using monoclonal antibodies by immunohistochemistry staining LSAB method and reverse transcription polymerase chain reaction (RT PCR). Results:There was significant correlation between CD1a(+) DCs and CD3(+),CD4(+) T lymphocytes, but no marked correlation between CD1a(+) DCs and CD8(+), CD25(+) T lymphocytes. No specific B7 mRNA expression was found in all specimens. Conclusions:DCs may not activate T lymphocytes efficiently. B7 gene was expressed at low level or deficiency in esophageal carcinoma may be one of the important reasons of failure to activate lymphocytes and induce the immunosuppression.

ObjectiveTo study the relationship between the antitumor immunoreaction and the cell apoptosis in esophageal carcinoma.MethodsThe IL-1β converting enzyme, Fas and FasL protein were labeled by LSAB immunohistochemistric method in 46 cases of esophageal carcinoma, of which 13 cases were labeled by TdT mediated dUTP nick end labeling (TUNEL).ResultsThe positive rates of ICE, Fas and FasL proteins in the cancer nests were 78.26%, 60.87% and 47.83%. The expression of ICE protein was related to the histological grading of the cancer.Conclusions The expression of Fas, FasL protein may be related to the immunological escape of the cancer cell; the expression of ICE was related to the histological grading of the cancer.
