Objective To investigate the prevalence features of helicobacter pylori (Hp) infection,anemia and iron deficiency in a po-pulation of Wuhan children with 2 to 6 years old,and the relationship between Hp infection and anemia,iron deficiency in the children.Methods Randomly taking 95 children who had taken tests in our hospital's check-up centre in 2008 as the study objects,2 kinds of exa-mination were employed to detect Hp infection.Serum levels of Hp-IgG were measured by enzyme linked immunosorbent assay (ELISA) methods to evaluate past infection.The 14C urea breath test (14C-UBT) was conducted to obtain information of the presence of current/active Hp infection.In the morning 3 mL fasting venous blood was collected to determine the serum levels of Hp-IgG antibodies and ferritin.Hemoglobin values were determined with a hemoglobinometer.Serum levels of C-reactive protein (CRP) were tested in order to determine whether the children had evidence of current inflammation or infection.In addition,demographic information such as age and gender of the children and information about their use of antibiotics within the prior month were recorded.All cases were divided into 2 groups including the Hp infection group and non-Hp infection group according to laboratory examinations,then the Logistic regression was applied to analyze the relationship between Hp infection and anemia,iron deficiency.The Kappa identity test was taked to compare the 2 measures.Results Of the 95 children,18.9% were anemic and 36.8% were iron deficient.Forty percent of the cohort had Hp-IgG antibodies,74.4% tested positive by the UBT.Presence of Hp-IgG emerged as a significant risk factor for anemia,iron deficiency in adjusted analysis controlling for demographic factors,current inflammation,and antibiotic use.Conclusions Findings from different measure of Hp may reflect different stages of infection,with UBT results reflecting an earlier stage of infection,and presence of Hp-IgG reflecting established Hp infection associated with anemia,iron deficiency.

Objective To investigate the osteoclast′s function levels in infants and toddlers and the relationship between the osteoclast function and sex,age,body length,body weight and body mass index(BMI).Methods Sixty-eight children(37 boys and 31 girls,aged from 1 to 36 months) were studied.All of the children were in good health.These children were divided as infants group and toddlers group according to their age.Just before the samples were collected,the children′s body weight,body length were measured and the BMI were calculated.Two biochemical markers,such as serum tartrate-resistant acid phosphatase 5b(TRAP5b) and urine deoxypyridinoline(DPD) were measured.Results The difference of serum TRAP5b concentration between infants and toddlers was significant at the level of P

Objective To observe whether the increase of oxidative stress in PC12 cells could influence the levels of protein carbonyls and nitrotyrosine and alter the cytoskeleton and cell morphology under clinostat condition,and whether the increase of content of nitrate/nitrite in cell culture medium could influence the cell proliferation and differentiation.Method Cell morphology,carbonylated actin and nitrotyrosinated tubulin,and mRNA and protein express of nNOS and iNOS were observed and determined with immunofluorescence and RT-PCR technology in clinostat rotated and control static groups.At the same time,cell density was measured and cell cycles were detected with flow cytometry.The relationship between all these changes and NOS were also analyzed.Result The levels of carbonylated and nitrotyrosinated cytoskeleton protein were altered,no obvious changes in cell morphology but neurite outgrowth after on a clinostat rotation.Cell density also increased significantly,DNA synthesis in cell cycles was shortened.Conclusion All of these results indicate that simulated weightlessness do not alter cell morphology and is beneficial to the growth of PC12 cells.The mechanism involved may be associated with the increase of NOS activity.

Objective To explore the application value of DOSE index score in the peitients with chronic obstructive pulmonary disease.Methods 122 cases of plateau COPD patients were followed up for 12 months,and we recorded and analyzed the patient's health and life.We also recorde FEV 1 and DOSE scores of the patients with COPD,and record the COPD risk events,including the number of respiratory failure and death,and the times of hospitalization,total such confinement,outpatient expenses,hospitalization expenses,mMRC,and scored in the number of exacerbations,etc.Results The DOSE index score was negatively correlated with FEV1％ pred (r=0.73,P ＜ 0.05) for 122 COPD patients,and were positively correlated with mMRC (r=085,P ＜ 0.01),the annual number of exacerbations (r=0.71,P ＜ 0.01),respiratory failure (r=0.65,P ＜ 0.01),heart failure (r=0.50,P ＜ 0.01),number of outpatient service (r=0.12,P＜0.01),hospitalization time (r=0.70,P＜0.01),the totalsuchconfinement (r=0.66,P＜0.01),outpatient expenses (r=0.13,P＞ 0.13),hospitalization expenses (r=0.65,P＜0.01).ROC curve was used to analyzed the cut-off point and curve area of COPD DOSE index.Conclusion The DOSE index is a simple COPD assessment tools,and is closely related to the prognosis of patients and health.

A combination product is a new model of the medical product that incorporates at least two of the regulated component categories of device, drug, or biological product into one product. It has become a new hot point within the development of devices and drugs, and has brought about a new opportunity for device and drug industries and a new challenge for administration too. In the paper, the properties of combination products are summed up and the impact on device and drug industries are discussed.

A pathogenic bacterial strain X1 was isolated from Siberian sturgeon (Acipenser baerii) suffering with bacterial septicemia. The 50% lethal concentration (LC50) of strain X1 was 5.62?105 CFU/mL, which showed that strain X1 was rather strong virulent to Acipenser baerii. Strain X1 was gram negative and 1.0 ?m～1.2 ?m ? 2.1 ?m～2.4 ?m in size with peritrichous flagella, and had ?-hemolytic activity on rabbit blood agar. By means of ATB expression identification and 16S rDNA sequence analysis, strain X1 was identified as Aeromonas hydrophila (locus number: EU669667), which was the closest relative to Aeromo-nas hydrophila strain ATCC35654 (locus number: X74676.1) with 99% homology. In addition, strain X1 was highly sensitive to cefoperazone and cravit, and intermediately sensitive to ten kinds of antibiotics in-cluding tobramycin, norfloxacin, sulperazone, kanamycin, gentamycin, fortum, vancomycin, neomycina, polymyxin B and lomefloxacin.

AIM: To analyze the composition, distribution and characteristics of the elderly primary ocular tumors.
METHODS: This was a retrospective study and all 504 cases with primary ocular tumors aged 60 years or older were collected in Shanxi Eye Hospital, during the year 2000- 2012. The onset age, location and pathological pattern were analyzed.
RESULTS: There were 346 cases of benign ocular tumors (68. 7%), and 158 cases of malignancy (31. 3%). Papillomas was the most common type of the benign with 83 cases (16. 5%), followed by a variety of inflammatory cysts and lesions with 69 cases ( 13. 7%) and 64 cases (12-7%) respectively. Among malignant tumors cases, eyelid basal cell carcinoma originated from epithelial was the most common with 72 cases (14. 3%), followed by skin appendages sources malignant tumors with 39 cases (7. 7%). Concerning the location of ocular tumors, there were 282 cases of eyelid tumor (56. 0%) occupied the first position followed by conjunctival tumor with 157 cases (31. 2%).
CONCLUSION: The prevalence and type of primary ocular tumor in elderly people are significant differences from the general population and children's, and the proportion of malignant tumors tended to increase along with the increase of age.
