Objective To study the self-identity and security of patients with obsessive-compulsive disorder (OCD) Methods According to the Chinese Classification of Mental Disorder,Third Edition,63 inpatients and outpatients with OCD and 61 healthy controls were recruited to investigate with self-identity scale(SIS),security questionnaire (SQ),Yale-brown obsessive compulsive scale (Y-BOCS),and self-made questionnaire.Results Compared with controls,patients had lower self-identity (50.81 ± 7.52 vs 55.10 ± 6.86,P ＜ 0.01)and security(50.09 ± 11.65 vs 58.87 ± 10.22,P ＜ 0.01)than healthy controls.Female patients had lower self-identity (48.31 ±7.68 vs 52.57 ±6.98,P＜0.05) than male patients.There were correlation between self-identity and Y-BOCS (r =-0.404,P ＜ 0.01),security and Y-BOCS (r =-0.314,P ＜ 0.05),self-identity and course of disease (r =-0.284,P ＜ 0.05),security and course of disease (r =-0.259,P ＜ 0.05) self-identity and security (r =0.698,P＜ 0.01) Conclusion OCD patients have lower self-identity and security.The self-identity and security reduce with the symptoms getting worse.Low self-identity and security maybe characteristic of OCD patients.

Objective To clone amastin coding genes from different strains of Leishmania parasites. Methods Using amastin cDNA sequence as the reference, dbEST data base established by National Center Biotechnology Information (NCBI), USA, was searched by BLAST tool. A 309 bp DNA fragment of Leishmania major was found and used as the probe for the screening of a DNA library. The amastin gene of Leishmania major Abdou was cloned and sequenced. Specific primers were designed and amastin genes for Leishmania mexicana WR972, Leishmania brizeliensis and Leishmania amazonensis joseph were amplified by polymerase chain reaction. Results The amastin genes from 4 strains of Leishmania parasites were cloned and sequenced. It was found that all 4 amastin genes contained unique open reading frame of 552 bp and encoded amastin protein of 183 amino acid residues. Conclusion The amastin genes of 4 strains of Leishmania parasites were successfully cloned.

Objective To investigate the effects of osteogenic growth peptide (OGP) in combination with extracorporeal shock waves (ESWs) on osteoblast proliferation.Methods Passaged cells were divided into four groups for different treatments:a control group,an OGP + ESW group,an ESW group,and an OGP group.After the respective treatments,the cells were cultured for 24 h,48 h and 72 h and counted using methylthiazdy tetrazolium (MTT) and an inverted fluorescence microscope. Immunohistochemical examination was used for detecting protein kinase A (PKA)activity,and a reverse transcription-polymerase chair reaction (RT-PCR) was used for examining PKA mRNA expression at 24 and 48 hours.Results Cell counting revealed that cell proliferation in the OGP + ESW,ESW and OGP groups was significantly promoted compared with the control group.Cell proliferation was greatest in the OGP + ESW group.The immunohistochemical examination showed positive staining intensities in the OGP + ESW,ESW and OGP groups significantly higher than in the control group.The positive staining intensity in the OGP + ESW group was again the highest.PKA activity was also significantly higher in the OGP + ESW,ESW and OGP groups than in the control group with the level in the OGP + ESW group the highest.Conclusion OGP in combination with ESW has a synergistic effect in stimulating osteoblast proliferation and growth.
