Objective To explore the clinical characteristics of coronary heart disease (CHD) companied by type-2 diabetes mellitus (DM) and features of their coronary angiographies. Methods The data of clinical characteristics and coronary angiography results of 108 CHD cases with T2DM and 103 CHD cases without T2DM were compared and analyzed. Results Compared with the cases of CHD without diabetes mellitus, the cases of CHD with T2DM exhibited significantly increased incidence rates of hypertension and dyslipidemia. The body mass index and serum uric acid level also increased obviously. The main manifestation of dyslipidemia of CHD patients with T2DM was the higher levels of triglycerides and lower level of serum high-density lipoprotein cholesterol. And the severe coronary artery disease and lower left ventricular ejection fraction were often found in CHD patients with T2DM Conclusion CHD patients with type-2 DM tend to have multiple cardiovascular-risk factors, and often have multi-branches lesion and more severe lesions.To treat cardiovascular risk factors actively is very important to prevent the CHD and improve its prognosis.

The study aims to solve the instability problem of methylphenidate (MPH) in plasma, and establish a LC-MS/MS method for simultaneous determining of MPH in human plasma. The stabilities of MPH in different media were studied, and the degradation characteristics of MPH in these media were also investigated by HPLC and LC-MS/MS. To a 200 microL aliquot of freshly collected plasma sample, 10 microL 2% formic acid was added immediately to prevent the hydrolysis of MPH in human plasma samples. Chromatographic separation was performed on a Sapphire C18 column using the mobile phase of methanol - 5 mmol.L-1 ammonium acetate buffer solution containing 0.1% formic acid (46 : 54). MPH was quantified by tandem mass spectrometry operating in positive electrospray ionization mode with multiple reaction monitoring. The detection used the transitions of protonated molecules at m/z 234.2-->84.1 for MPH and m/z 260.3-->183.1 for propranolol (IS), separately. The intra- and inter-assay precisions were all below 5.0%. The accuracies were all in standard ranges. The linear calibration curve was obtained in the concentration range of 0.035-40 ng.mL-1. The methods fulfilled the demand. The method was used to determine the concentration of MPH in human plasma after a single dose of 36 mg MPH tablet to 6 healthy Chinese volunteers. The method is suitable for the precisely determination of MPH and for pharmacokinetic study of MPH in human plasma.

A protocol for enrichment and adsorption of karyocyte from whole blood by using magnetic nanometer beads as solid-phase absorbents was presented. The PCR amplification could be accomplished by using the nanobeads with karyocyte as template directly and the PCR products were applied on an oligonucleotide array to do gene typing. The HLA-A PCR amplification system and a small HLA-A oligonucleotide microarray were applied as the platform and an experiment protocol of separating karyocyte from whole blood using the magnetic nanometer beads (Fe2O3) were set up. The experimental conditions were also discussed. It showed that pH level of PBS eluent, Taq enzyme quantity and fragment length of products could influent the amplification results, and the magnetic nano-beads could succeed in sample preparation in microarray to provide a promising way in automatic detection and lab-on-a-chip.

OBJECTIVE:To evaluate the economics of alendronate sodium preventing osteoporotic fractures in postmenopausal women,and to provide reference for osteoporotic and osteopenia patients to select economical and effective therapy plan. METH-ODS:Using Markov economic model,TreeAge Pro 2011 software was used for cost-utility analysis using RCTs literature data of basic medication(calcium and vitamin D3)and basic medication combined with alendronate sodium as baseline data. Using quality adjusted life years(QALYs)and incremental cost utility ratio(ICUR)as economics evaluation indexes,the stability of established model was investigate by single factor sensitivity analysis. RESULTS:QALYs of the basic treatment group was 0.704 years,and QALYs of drug combination group was only 0.708 years. However,ICUR of two groups reached 714252.44. For the late period of hip fracture and other fractures,drug combination group was in high cost and low benefit,obviously had no economic advan-tage. For vertebral fractures,the cumulative probability of fracture in drug combination group was significantly lower than basic treatment group,and ICUR of the two groups was only 13902.17,with economic advantage. For hip fracture,the cumulative prob-ability of fracture in basic treatment group was the same as drug combination group,and ICUR was 19109.00,with economic ad-vantage. For wrist fractures,curative effect and economy needed further study. CONCLUSIONS:For the low-risk population with osteoporotic fractures,calcium and vitamin D3 are more economical in preventing osteoporosis fractures. For the high-risk popula-tion with vertebral and hip fractures,alendronate sodium combined with basic treatment is effective and economical.

Objective To investigate the clinical phenotype, genotype and ultrastructural features in a pedigree with autosomal recessive congenital ichthyosis. Methods Patients were examined for clinical manifestation. PCR was carried out to amplify all the 15 exons and adjacent splice sites of TGM1 gene followed by bidirectional sequencing. Skin samples were taken by biopsy from the back of the proband, fixed in 3% glu-taraldehyde for transmission electron microscopy. Results The proband presented an intermediate clinical phenotype between lamellar ichthyosis (LI) and non-bullous congenital ichthyosiform erythroderma (NCIE), while his brother manifested as a collodion baby. A C551T heterozygous mutation which located in the third exon of TGM1 gene and resulted in a substitution of arginine by cysteine at codon 143 (R143C), was detected in the proband, his brother and father. Meanwhile, another heterozygous C-to-T transition at position 759 causing a substitution of serine by phenylalanine at codon 212 (S212F), was noted in the proband, his brother and mother. Electron microscopy revealed not only features of ichthyosis congenital type Ⅲ but also those of ichthyosis congenital type Ⅱ in lesions of the proband. Conclusions The patients in this pedigree carry compound heterozygous mutations, i.e. R143C, a hot missense mutation, as well as a de novo mutation S212F. The proband, who harbors mutations in the TGM1 gene, shows electron microscopic features characteristic not only of ichthyosis congenital type Ⅱ but also of ichthyosis congenital type Ⅲ.
