To study the cellular pathophysiological change in kidney IMCD cell under respiratory acid base disorders. 3% or 10% CO 2 was used to initiate chronic respiratory alkalosis(ALG) or chronic respiratory acidosis(ACG) of cultured rabbit IMCD cell. 5% CO 2 was used in control group(CG). Fluorescent probe was used to measure H + /K + exchange function of these cells. In situ hybridization and RT PCR were used to measure cH K ATPase mRNA expression of these cells.The results showed that H + /K + exchange in ACG was significantly higher than that in CG ( P 0 05). It is suggested that chronic respiratory acidosis could induce an increase in H + /K + exchange function and cH K ATPase mRNA expression. However, chronic respiratory alkalosis could induce decreases in H + /K + exchange function and cH K ATPase mRNA expression with no statistical significance, the reason of which calls for further study.

Objective To observe anomalous genotypes of 4 multi-copy RM Y-STRs in Han population in Hubei province. Methods 252 unrelated male samples were ampliifed using reported and newly designed primers, then detected and analyzed by AB 3130 genetic analyzer. Results A total of 25 anomalous multi-band patterns were observed in 20 samples corresponding to an incident rate of 7.94%. 5 anomalous genotypes were observed in DYF387S1 locus, 15 in DYF399S1, 1 in DYF403S1 and 4 in DYF404S1. Four samples showed extra alleles in more than one locus. Conclusion Anomalous genotype has high incident rates in RM Y-STR markers and requires extensive attention in forensic practice.

Objective To establish a method for determination of 2-chloroacetamide in cosmetics. Methods The gas chromatography method had been developed for determination of 2-chloroacetamide in cosmetics. Samples were solved with ethanol treated with ultrasonic homogenization centrifuge separated by HP-INNWax column determined by FID. Results The 2-chloroacetamide concentration had a better linear range in the range of 0.0-10.0 mg/ml. The minimum detection limit was below 0.01 ?g. The relative standard deviation was less than 5.6% and the recovery rates were 90%-100% respectively. Conclusion This method is simple fast and sensitive.

Objective To investigate the application of computer radiography system in combination with high kV radiography technique to diagnose cardiac disease.Methods 30 patients with cardiac disease were taken chest photographs,which chest photographs by CR system and high kV radiography technique were compared with these by common high kV radiography.Results The good rate of air tube occupied is 98% in therapy group,but the rate is only 70% in common group.The discrepant comparison is significant differences.Conclusion It is more significant that CR system in combination with high kV radiography technique than common photograph to diagnose cardiac disease.

Attention-deficit/hyperactivity disorder (ADHD)is one of the most common comorbidities of ASD.This article reviews the assessment tools and clinical research (prevalence,clinical characteristics and treat-ment)and fundamental research (iconography,genetics,neurophychology,electronerophysiology)of ASD with ADHD according to lately related articles.The findings suggested that there was lack of researches on treatment and iconography of ASD with ADHD and the conclusions were inconformity.Furthermore,most of the objects in these researches were children of normal intelligence.Thus future research should expand its objects to patients of adult and children with mental retardation and do further explore in iconography and treatment.

Objective To explore the feasibility of tubular model based segmentation method for cystic artery and three-dimensional (3D) reconstruction model of Calot's triangle.Methods A tubular model based 3D region growing algorithm was proposed for the segmentation of cystic arteries and its adjacent vessels from 13 patients' CT images in DICOM format.The data was transferred to 3D visualization workstation based on a set of CalotShow1.0 software for 3D reconstruction.Results The method could effectively segment cystic artery and obtain the 3D model of Calot's triangle.Conclusions The 3D reconstruction model based on tubular model related vessel segmentation method and CalotShow1.0 can accurately display the spatial positions and adjacent relationships of cystic artery and Calot's triangle.

Nitrogen source is one of the important factors that affect the microalgae growth and lipid accumulation. We studied the effects of various nitrogen sources (i.e. NaNO3, CO(NH2)2, NH4Cl and CH3COONH4) and amount on the growth density, lipid yield, and eicosapentaenoic acid (EPA) content of Nannochloropsis oculata by single factor experimental method. The results show that N. oculata preferred NH4+ as nitrogen source rather than NO3- and CO(NH2)2. NH4+ could promote the growth and lipid accumulation of N. oculata. With the increase of nitrogen concentration, the biomass and the content of polyunsaturated fatty acid (PUFA) increased, but the content of lipid decreased. CH3COONH4 was the most suitable for growth, accumulation of lipid and EPA of N. oculata among the four investigated nitrogen sources. The optimal concentration was 5.29 mmol/L.
