OBJECTIVETo measure hip bone mineral density (BMD) on different femoral rotations and to identify the influence of femoral rotation during hip densitometry.
METHODSForty women were recruited at the out-department of orthopedic, with the average age of 60.7 years (45-85 years), the average height of 161.8 cm (150-175 cm), and the average weight of 67.4 kg (48-80 kg). BMD measurement of hip was done in neutral position (0 degrees), 15 degrees and 30 degrees of internal rotation under quality control of DXA machine. All the subjects were asked to get down scan table and reposition after each measuring in different rotation.
RESULTSHip BMD of proximal femur (femoral neck, Ward's area and trochanter region) have significant variations in measurement (P < 0.01) among neutral position, 15 degrees and 30 degrees of internal rotation. There were more BMD change at the cancellous region (Ward's triangle and trochanter region) than at cortical bone area (femoral neck region). Statistical analysis showed a significant positive correlation for hip BMD change between neutral degrees to 15 degrees of internal rotation and 15 degrees to 30 degrees of internal rotation. But no correlation between neutral degrees to 30 degrees of internal rotation for hip BMD change.
CONCLUSIONSFemoral rotation was shown to have a significant effect on hip BMD measurements. Cortical bone region of hip have a less BMD change than cancellous bone region. Proper positioning of the femur during scan can improve precision significantly.

The paper is aimed to study the dynamic accumulation regulation of curcumin (Cur), demethoxycurcumin (DMC) and bisdemethoxyeurcumin (BDMC) in three strains of Curcuma longa, and provide scientific references for formalized cultivation, timely harvesting, quality control and breeding cultivation of C. longa. The accumulation regulation of the three curcumin derivatives was basically the same in rhizome of three strains. The relative contents decreased along with plant development growing, while the accumulation per hectare increased with plant development growing. The accumulation of curcuminoids per hectare could be taken as the assessment standard for the best harvest time of C. longa. A3 was the best strain in terms of Cur and BDMC content.

OBJECTIVETo explore the possibility of using an endovascular microcoil as a gene delivery system.
METHODSAnti-adenoviral monoclonal antibodies were covalently attached to the collagen-coated surface of platinum microcoil. These antibodies were used to tether adenovirus encoding green fluorescent protein (Ad-GFP). Cell culture studies with rat arterial smooth muscle cells (A10) assessed transduction on or near the coil. Platinum coils coated with Ad-GFP were implanted into the ligated common carotid artery (CCA) of adult rats in a model of arterial stasis and pressurization. After 7 days, CCA segments were harvested, and coils were removed for histopathology and GFP expression studies, while organs were evaluated by polymerase chain reaction to assess viral biodistribution.
RESULTSIn cell culture studies, GFP-positive smooth muscle cells were detected only on the platinum coil surface. After 7 days, GFP was detected on the harvested platinum coil and in the organizing thrombus within the CCA according to fluorescence microscopy and immunohistochemistry. Morphometric analyses revealed that (13.3 +/- 2.0)% of cells within the organized thrombus were transduced with Ad-GFP via the gene delivery system. Ad-GFP was not detectable by polymerase chain reaction in lung, liver, or kidney.
CONCLUSIONSGene delivery endovascular microcoils represents an interventional device-based gene therapy system that can serve as a suitable platform for either single or multiple gene therapy vectors.

In order to explore the genotype distribution and molecular evolution of non-polio enterovirus (NPEVs)in Yunnan Province,the People's Republic of China, we sequenced and analyzed the partial VP1 coding region of 105 NPEVs isolated from acute flaccid paralysis (AFP) surveillance in Yunnan province during a 5- year study period from 2006 to 2010. The viral genomes of 105 NPEVs were translated to corresponding amino acid sequences and compared with those of the prototype strains, and the phylogenetic tree was constructed among these VP1 nucleotide sequences and other prototype strains from GenBank. Analysis showed that 18 isolates were classified into 7 serotypes of human enterovirus A species, while 77 isolates into 22 serotypes of B and 10 isolates into 4 serotypes of C species. However, we did not isolate any viruses which belonged to human enterovirus D species. Thus, under AFP surveillance, human enterovirus B species accounted for 73. 3% of the 105 isolates and was considered as the predominant one,followed by human enterovirus A(17. 1%) and human enterovirus C(9. 5%). Phylogenetic analysis showed that various serotypes of the virus and the corresponding prototype strains or other representative strains clustered into the same grooup, however, Yunnan strains and prototype strains were located in the different branches (except CA2,EV90 and EV76). The degree of variation was different even among the same genotype strains. This report showed that different genotype strains spread widely in Yunnan Province.

OBJECTIVETo investigate the association of -689C/T polymorphism in the peroxisome proliferator-activated receptor-gamma2 (PPARgamma2) promoter with myocardial infarction (MI).
METHODSThis is a case-control study, which included 194 subjects with MI and 693 subjects without MI in nondiabetic Han population in Wuhan. Polymerase chain reaction-restriction fragment length polymorphism was used to determine the -689C-->T substitution.
RESULTSThe CC,CT, and TT genotype frequencies of -689C/T polymorphism were 88.1%,11.9%,and 0.0 in MI patients and 93.1%,6.6%,and 0.3% in controls, respectively (CC vs. CT+TT, P=0.025). The -689T allele was an independent risk factor for MI (OR=2.125, 95%CI: 1.206-3.744, P=0.009) after adjusting for age,sex,waist circumference,body mass index, smoking, alcohol drinking, physical activities, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, level. The -689T allele carriers had significantly higher TC levels than noncarriers [(5.05+/-1.16) mmol/L vs. (4.78+/-1.05) mmol/L, P=0.004] in the total population.
CONCLUSIONThe PPARgamma2 promoter -689C/T polymorphism is associated with an increased risk of MI.
