Objective To explore the distrbution characteristics of glutathione S-transferase T1 and M1 (GSTT1 and GSTM1) gene polymorphism of Daur population in Inner Mongolia region, and provide the relevant data for studying the genotype of minority ethnic group of the Inner Mongolia.Methods Genomic DNA was extracted from peripheral blood and the fragments of GSTM1 and GSTT1 was amplified by internal control allele specific PCR in 220 volunteers who had been residents in Inner Mongolia region. At the same time, the genotype of GSTT1 and GSTM1 was resolved by the density of 2.5% agarose gel electrophoresis.Results In the studied population, the frequencies of GSTM1 (-) and GSTT1 (-) were 50.8% and 71.4% respectively. The frequency of the individuals with combination of GSTM1 (-) and GSTT1 (-) was 31.4%.Conclusion The distribution of GSTM1 and GSTT1 displays gene polymorphism in Chinese Daur population, approximate to Mongolian population in the north of China, but there is significant difference between Chinese Daur population and Han people.

Objective:To evaluate the current situation and the developing trend of 5-HT3 receptor antagonists used in 25 hospital of Wuhan during the period of 2003～2005 in order to provide reference for clinical doctors and pharmacists. Method:The 5-HT3 receptor antagonists were statistically analyzed in respect to the purchase sum of money,DDDs and daily costs. Result:During the 3 years, purchase sum of money of 5-HT3 receptor antagonists were yearly increasing. The share of the market of domestic drugs showed an increasing tendency,while the imported drugs decreased year by year. Granisetron, ondansetron and tropisetron were much more frequently used than others. Conclusion:The market of the oral agents of 5-HT3 receptor antagonists will further expand in China.

Objective To explore the risk factors and imaging features of silent brain infarction (SBI).Methods The patient with SBI from the clinic were enrolled in the study,and the patients with symptomatic non-lacunar infarction served as controls.The risk factors and imaging features of both groups were compared.Results Among 145 patients with SBI,133 (91.72％) had two or more lesions,mainly in the centrum semiovale (73.10％).The proportion of patients with white matter lesions in the group of SBI in a single location was significantly lower than that in the group of SBI in multiple locations (41.67％ vs.73.68％ ;x2 =5.484,P =0.019).Compared to the patients with SBI,the age in patents with symptomatic non-lacunar infarction was older (72.42 ± 11.79 vs.67.03 ± 12.04 years; t =3.545,P =0.000),the proportions of male (63.55％ vs.46.21％ ;x2 =7.447,P =0.006),hypertension (80.37％ vs.64.14％ ; x2 =7.887,P =0.005) and atrial fibrillation (31.78％ vs.8.97％,x2 =21.113,P =0.000),as well as the levels of fasting glucose (6.09 ±1.23 mmol/Lvs.5.65± 1.18 mmol/L; t=2.863,P=0.005),total cholesterol (5.53± 0.74 mmol/Lvs.5.27 ± 0.90 mmol/L; t =2.554,P =0.011),triglycerides (1.89 ± 0.20 mmol/L vs.1.77 ± 0.18 mmol/L; t =4.910,P=0.000) and homocysteine (1 4.88 ±4.97 mmol/L vs.11.94 ±4.61 mmol/L; t =4.432,P =0.000)were higher.However,the lipoprotein (a) level was lower (0.18 ± 0.06 g/L vs.0.27 ± 0.18 g/L; t =-5.489,P =0.000).Among patients with SBI,33.8％ and 43.5％ had lesions in two and three locations,respectively;among patients with symptomatic non-lacunar infarction,66.4％ and 27.1％ had lesions in a single location and two locations,respectively (P ＜ 0.001).Multivariate logistic regression analysis showed that lipoprotein (a)was the independent risk factor for SBI (odds ratio 5.988,95％ confidence interval 2.421-14.706; P =0.000).Conclusions Although they shared a variety of common risk factors,patients with SBI had less atherosclerotic risk factors than those with symptomatic non-lacunar infarction.Most patients with SBI had lesions in multiple locations.

Objective To develop ICU digital system for over-all monitoring and remote monitoring.Methods The programming and design was performed according to the principles of"taking patients as center,clinic as basis,utility as goal,service as aim".Results ICU digital system was composed of digital medical instruments and their clinical Gateway,intensive care information system,bedside integrated clinical information terminals,nurse workstation integrated clinical information terminals,serious patients visit system,little smart local communication system,consultation demonstration teaching system and personal digital assistant clinical information terminal system.Conclusion As one of the important symbols of modern hospital,the ICU digital system integrates the vital signs information of every patient in ICU and implement seamless connection with CIS,LIS,PACS,HIS.The construction of ICU digital system will accelerate the digital hospital's development.

The development of proteomic technique has sparked new focus on novel protein markers for many diseases including cancer. Urine is one of the most useful biofluids for routine testing to provide an ideal resource for the discovery of novel biomarkers, with the advantage over tissue biopsy samples due to the ease and the less invasive nature of urinary collection. This review summarizes urinary protein tumor markers found in prostate cancer, bladder cancer, lung cancer and breast cancer that have shown potential for urogenital and non-urogenital cancer, so as to provide reference on high sensitive and high specific urinary protein tumor markers for early prevention, early diagnosis and treatment of cancer.

Objective To develop a sensitive, specific, rapid and easy method for detecting E. coli O157 : H7 and other Shiga toxin-producing E. coli in food and clinical specimens. Methods A circular probe and capture probe specific for Shiga toxin-2 (stx2) gene had been synthesized and was used for determining the sensitivity of ramification amplification method (RAM). Different serotypes which contained stx2 gene, including an E. coli O157 : H7, an E. coli O46 : H38, an E. coli O111 : NM, an E. coli O22 : H8 and E. coli ATCC23716 (stx2 gene negative) were used for determining the specificity. All strains were detected by RAM to determine whether they contained stx2 gene. Real-time RAM was further studied to detect stx2 gene. Results The lowest number targets detected by RAM assay was 10 copies of stx2, indicating that RAM assay was as sensitive as conventional PCR. The result of specificity showed that different serotypes of strains were all positive for stx2 gene, while nonpathogenic E. coli ATCC23716 was negative. Among 32 isolates, 28 STEC isolates containing stx2 gene were positive by RAM assay, while others were negative. The RAM results were 100% in concordance with that of PCR. The real-time RAM results also showed that as many as 10 bacteria can be detected and the time of appearance of detectable signal was depended on the target concentration. Conclusion RAM assay can offer an alternative method for PCR to detect E. coli O157 : H7 and STEC in all types of specimens because of its simplicity and isothermal amplification.

Objective To observe the effect of sinomenine on the proliferation of fibroblast-like synoviocytes (FLS) and expression level of MMP-3 secreted by FLS in rheumatoid arthritis in vitro. Methods FLS were obtained by digesting synovial tissues with collagens and were divided into four groups:sinomenine high, middle, low concentration and control group. The proliferation of FLS was assessed by methyl- thiazolyl-tetrazolium (MTT) assay and the mRNA expression of MMP-3 was measured by semi-quantitative RT-PCR respectively after treated by sinomenine. Results The rate of FLS proliferation was significantly reduced in groups treated by sinomenine. Compared with control group, the mRNA expression of MMP-3 markly decreased in sinomenine groups (P
