1.Progress in CRELD1 gene on atrioventricular septal defect
International Journal of Pediatrics 2011;38(1):36-37,40
Congenital heart disease(CHD) is a series of birth defect that can actually or potentially impact heart function , occurring 4‰~ 12‰ of live birth. Atrioventricular septal defect (AVSD) is a frequently CHD affecting the atrioventricular valves and septa. AVSD refers to a clinical spectrum of defects ranging from a complete AVSD to cleft mitral valve. AVSD occurs most frequently in Trisomy 21 syndrome. Research shows that the development defect of endocardial cushion caused by heredity and environment during different period of heart development leads to all kinds of AVSD. CRELD1 is the first identified gene associated with morbidity of AVSD.The research on this gene has important significance to find out the pathogenesis of AVSD and provide better prevention and cure methods.

Chinese Journal of Medical Imaging 2015;(2):131-134,139
PurposeTo explore CT and MRI findings of pigmented villonodular synovitis (PVNS) of spine, and to improve the preoperative diagnosis.Materials and MethodsCT and MRI findings of 7 cases of PVNS of spine confirmed by surgery and pathology were retrospectively analyzed. Seven cases underwent CT scan and 5 of them underwent MRI scan. The location of the lesions, tumor size, shape, density (signal), bone destruction and enhanced features were analyzed.ResultsExcept one case with small lesion, the remaining 6 cases showed lobulated soft tissue masses centering at the facet joint area, with lytic, expansive bone destruction. On CT images (n=7), 3 cases showed the masses density similar to that of the surrounding muscles, and 4 cases showed the tumor density slightly lower than that of the surrounding muscles. On MRI images (n=5), 1 small lesion demonstrated low signal at the peripheral, 1 lesion was isointensity without obvious low-density in it, 3 cases showed characteristic multiple visible low signal nodules in the lesions.ConclusionThe possibility diagnosis of the PVNS should be considered when spinal lesions are characterized by osteolytic bone destruction centering at facet joints and soft tissue masses with distinctive MR signals.

Aim To observe the effect of a treatment proposal named “Golden Triangle” ( Atorvastatin, Tongxinluo,and Aspirin) on the vasa vasorum angio-genesis of early atherosclerosis lesions in rabbits carotid artery. Method Seventy-two healthy New Zealand rabbits with half males and half females were divided into 6 groups randomly ( n =12 ):control group, model group, Tongxinluo group ( TXL ) , atorvastatin group ( ATO ) , aspirin group ( ASP ) , golden triangle group ( ATS) . The control group was fed with common feed-stuff, and all the other groups′ right carotid arteries were equipped with the silicone tube,and were then fed with fatty feedstuff. The Tongxinluo group, the Atorvas-tatin group and the Aspirin group were given suspen-sion of Tongxinluo supermicro powder(0. 3 g·kg-1 · d-1 ) , Atorvastatin ( 2. 5 mg · kg-1 · d-1 ) and Aspirin (12 mg·kg-1·d-1),the golden triangle group were given suspension of Tongxinluo supermicropowder (0. 3g·kg-1 ·d-1),atorvastatin(2. 5 mg·kg-1 · d-1 ) and Aspirin ( 12 mg · kg-1 · d-1 ) . All the groups were fed with medicine for 4 weeks. Tissue slice of carotid artery was stained with HE and observed un-der light microscope. The change of blood liquid was detected by biochemical assay. Immunohistochemical staining was used to detect the protein expression of CD34 around the carotid artery adventitia. Color micro-sphere method was used to detect the blood flow vol-ume change of the cartoid artery microvascular. VEFG, VEGFR-2 gene and protein expression in the cartoid artery were detected by Real-time PCR and Western Blot. Result Compared with the control group,the content of VEGF, VEGFR-2 gene and pro-tein expression and the microvascular blood flow vol-ume of cartoid artery microvascular in the model were significantly increased ( P <0. 01 ) . But those in each drug group were lighter than those in the model group (P<0. 01,P <0. 05). In the ATS group,the content of VEGF, VEGFR-2 gene and protein expression and the microvascular blood flow volume of cartoid artery microvascular were lower than those in the TXL, ATO and ASP group ( P <0. 01 , P <0. 05 ) . Compared with the ASP group,the content of VEGFR-2 protein expres-sion was significantly decreased(P<0. 01)in the TXL and ATO group. VEGF,VEGFR-2 gene and protein ex-pression in different subgroups showed no significant difference( P >0. 05 ) . The content of CD34 was de-creased in TongxinLuo group,atorvastatin group,aspirin group and ATS group. Conclusion The ATS project can reduce the expression of VEGF,VEGFR-2, inhibit the vasa vasorum angiogenesis and decrease proinflam-matory substances in the tunica media and intima of vascular wall. It plays an important role in intervening in the process of AS.
