Tianjin Medical Journal 2010;38(1):1-3
Objective:To identify the novel intronic transcripts containing 11q13.5 HERV-W gag sequence, and explore the modulation of the transcripts on the alternative splicing of host gene PTD015. Methods:Half-nested PCR and touchdown PCR were used to amplify the target transcripts. The transcripts were cloned and sequenced. The plasmids inserted with the target transcripts were transfected into JEG3 cells and the alternative spliced mRNA levels of PTD015 were measured with real time PCR. Results:A 1 739 bp novel intronic transcript containing 755 bp 11q13.5 HERV-W gag sequence, 527 bp 5′ long terminal repeat and 457 bp sequence on the 5′-end of 11q13.5 HERV-W was identified. The intronic antisense transcripts significantly down-regulated the alternative spliced mRNA levels of PTD015. Conclusion:The intronic antisense transcripts originating from the second intron of gene PTD015 could modulate the alternative splicing of the host gene PTD015.

8.Relationship between genetic polymorphism of dopamine receptor and schizophrenia and its forensic significance.
Journal of Forensic Medicine 2014;30(3):202-206
Schizophrenia is a common but complex mental disorder affected by multiple factors. Forensic psychiatric assessment of schizophrenia involves evaluations on many aspects, but there is no effective biological identification index for schizophrenia. Researches indicate that dysfunction of dopaminergic neurotransmission plays an important role in the pathogenesis of schizophrenia. Our study reviews the classification, genetic structure of dopamine receptors and the recent pertinent studies between the dopamine receptors and schizophrenia and its forensic significance.

Aim To study the effects of Bauhinia championii flavones ( BCF ) on adjusting autophagy a-gainst myocardial ischemia reperfusion injury. Meth-ods 120 SD rats were randomly divided into control, model, 3-MA (15 mg·kg-1 ) and BCF (10, 20 mg ·kg-1) groups (n=8). 30min. ischemia, ischemia/reperfusion 1h. or 3h, while myocardial ischemia reperfusion model was established by ligating left ante-rior descending coronary artery. The contents of crea-tine kinase-MB ( CK-MB) , inducible nitric oxide syn-thase ( iNOS ) and total antioxidative capacity ( T-AOC ) in serum were determined according to the ultra-violet spectrophotometer colorimetric method. The pro-tein expression of LC3-Ⅱ, Beclin-1 and mTOR was observed by Western blot. Results Compared with model group, BCF dose-dependently improved T-AOC, decreased CK-MB and iNOS ( P < 0. 05 ) . Meanwhile, BCF down-regulated the protein expression of LC3-Ⅱand Beclin-1 , and up-regulated mTOR pro-tein expression ( P < 0. 05 ) . Compared with 3-MA group, BCF reduced the contents of CK-MB and iN-OS, increased the level of T-AOC. It raised LC3-Ⅱand Beclin-1 protein expression at 30min. of ischemia, and then declined the protein expression of LC3-Ⅱand Beclin-1 . BCF descended the protein expression of mTOR all over the time ( P <0. 05 ) . Conclusion Autophagy occurs in ischemia then improves in ische-mia/reperfusion period. BCF could promote the occur-ring of autophagy at 30min. of ischemia in the short term and inhibit the excessive expression of autophagy with the increase of time in reperfusion period. BCF pretreatment reduce myocardial ischemia/reperfusion injury may by promoting the occurrence of autophagy during ischemia period and inhibit them in reperfusion.
