Background During the past two decades, a number of rating scales were developed to facilitate diagnosis and assessment of subjects with social anxiety disorder. One of the most commonly used scales for the assessment of social anxiety disorder is the Liebowitz social anxiety scale (LSAS). The LSAS is widely used in epidemiologic investigations and clinical researches,and its assessment in the pharmacotherapy efficacy for social anxiety disorder is superior to any other scale. So we designed this study to explore the validity and reliability of the LSAS in Chinese patients with social anxiety disorder and normal control, and to find the difference of the scores between the patients self -report version and clinician-administered version. Methods Fifty five patients meeting the DSM-Ⅳ diagnostic criteria for social anxiety disorder and 168 normal controls who were screened from 222 college students were rated by LSAS, social phobia scale and self-made General Information Forms. Results The Cronbath α of LSAS for the patients and the normal controls was 0.83 and 0.77, respectively. The 4-week test-retest reliability for total scores and its factors scores of LSAS in 31 normal controls were ranging from 0.68 to 0.79. The ROC area under curve value in discriminating the patients from normal controls was 0.87±0.03; the total score of 35 was considered to be the best cut-off score for LSAS, then its sensitivity was 0.77 and its specificity was 0.81; and no significant difference between the self-report version and clinician-administered version. Conclusions The LSAS is good in internal consistency and test-retest reliability, and has high sensitivity and specificity in discriminating the patients and the controls. There is no significant difference in the total score and each factor scores of LSAS between self-report version and clinician-administered version.

Objective To investigate the expression and clinical significance of serum microRNA (miRNA) expression profiling in the occurrence and progression of diabetic nephropathy.Methods The miRNA expression profiling was detected by miRNA TaqMan Low Density Array chip from 10 patient with diabetic nephropathy,10 diabetes patients with normoalbuminuria and 10 health control.Real-time quantitative PCR was applied to verify the result of miRNA array in serum samples of 66 patients with diabetic nephropathy (36 patients with microalbuminuria,30 patients with macroalbuminuria),40 diabetes patients with normoalbuminuria and 40 health control.And the relationship of differetial expression with clinical features was analyzed.Results miR-150-5p,miR-155-5p,miR-30e-5p and miR-3196 being validated by real-time quantitative PCR differentially expressed in 3 groups of serum samples from the diabetes patients with microalbuminuria (n=36),with normoalbuminuria (n=40) and health control (n=40) (P ＜ 0.05).Serum miR-150-5p (P=0.005) and miR-155-5p (P=0.006) changed significantly between diabetes patients with microalbuminuria (n=36) and with macroalbuminuria (n=30).Compared with the diabetes patients with microalbuminuria,serum miR-150-5p and miR-155-5p increased by 2.3 and 1.5 times in macroalbuminuria group,respectively.Estimated glomerular filtration rate and urinary albumin excretion rate significantly correlated with serum miR-150-5p and miR-155-5p level.Conclusions miR-150-5p and miR-155-5p may be involved in the process of pathological mechanisms of diabetic nephropathy.Serum miR-150-5p and miR-155-5p may be regarded as potential biomarkers to diagnosis the occurrence and development of diabetic nephropathy.

A total of 105 patients with first-episode schizophrenia (male =51,female =54) and 99 normal controls (male =51,female =48) were included into this retrospective case-control study.Childhood trauma questionnaire-28 item short form (CTQ-SF) was used to assess the experience of childhood abuse.The result of binary logistic regression showed that emotional abuse (β =0.630,P ＜ 0.05) and emotional neglect(β =0.270,P ＜ 0.05) were included into the final model of predicting schizophrenia.It indicates that patients with first-episode schizophrenia experienced more early life stress than controls.Particularly emotional abuse and emotional neglect may play important roles in the onset of schizophrenia.

OBJECTIVE: To investigate the expression of matrix metalloproteinase-1 (MMP-1), E26 transformation-specific-1 (Ets-1) in laryngeal carcinoma and to discuss their relevance and the roles in carcinogenesis and development of laryngeal carcinoma. METHOD: Immunohistochemical technique was used to detect the expression of MMP-1 and Ets-1 protein in 34 tissues of laryngeal carcinoma and 34 para-carcinoma tissues, 15 cases of vocal cord polyps, and the use of the pathological image analysis software, we analysis the results of immunohistochemical semi-quantitatively. RESULT: (1) The expression of MMP-1 and Ets-1 protein in laryngeal carcinoma tissues is obviously higher than that in para-carcinoma and in vocal cord polyps respectively (P < 0.05). There is no significant difference between the expression of para-carcinoma and vocal cord polyps(P > 0.05). (2) The expression of MMP-1, Ets-1 protein isn't related to patients' age and sex, tumor size,clinical classification (P > 0.05), but related to pathological grade, clinical stage and lymph nodes metastasis (P < 0.05). (3) There is a positive correlation between the expression of MMP-1 and Ets-1 in laryngeal carcinoma. CONCLUSION Overexpression of MMP-1 and Ets-1 was observed in laryngeal carcinoma. The high expression of MMP-1 and Ets-1 may contribute to the carcinogenesis and development of laryngeal carcinoma,which is a important value to judge the malignant degree and progress of laryngeal carcinoma.
