Objective To compare the prevalence of overweight and obesity in urban children in Chongqing city with 3 different refe-rences and find the appropriate reference for obesity-related study in children.Methods A cross-sectional study including 12 534 urban children aged 2-18 years old was performed.The data were selected from 3 districts in Chongqing city by multistage random cluster sampling.Children′s body height and weight were measured with unique method by trained doctors.Body mass index (BMI,kg/m2) was calculated for each child.Overweight and obese children were defined according to WHO weight-for-height reference values of urban children (1995,standard 1), International Obesity Task Force (IOTF) age-and gender-specific BMI cut-offs (2000,standard 2),and National Center for Health Statistics / Center for Disease Control and Prevention(NCHS/CDC)age-and gender-specific BMI cut-offs(2000,standard 3),respectively.Results The prevalence of overweight in all children was 13.0%,9.8%,and 9.8%,and the prevalence of obesity in all children was 9.8%,2.9%,and 6.0% by using the standard 1,standard 2 and standard 3,respectively,which showed significant differences between the references (Pa

In the process of hospital practice,the author deeply feels that the work of medical equipment tendering plays an important role in hospital construction and development,as well as promoting competence.The article discusses how to improve and perfect the medical equipment tendering based on its importance.

Object To search for bioactive secondary metabolites from marine organisms, the marine sponge Cinachyrella australiensis was collected from Hainan Island, Southern China Sea to develop the efficient drug for human beings. Methods Silic gel flash chromatography in association with reverse phase semipreparative HPLC was performed for the isolation and purification of the ethanol extracts, and extensive spectroscopy including 2D NMR spectra as well as the comparison of the spectral data with those reported in literatures was applied for the structure elucidation. Results Seven nucleotidoids were isolated and identified. They are named as 2-methyl-6-amino-9-(2-deoxy-?-D-ribofuranosyl)-purine (Ⅰ), 2′-deoxyadenosne (Ⅱ), 6-amino-9-?-D-ribofuranosyl-9H-punne (Ⅲ), uracill (Ⅳ), thymine (Ⅴ), thymidine (Ⅵ), 1-(2-deoxy-?-D-ribofuranosyl) uracil (Ⅶ). Conclusion The sponge C. australiensis is systemically separated, and then two kinds of nucleotidoids compound are extracted.

Objective To investigate the expression of CD2 in peripheral blood T lymphocytes in acute rejection after small bowel transplantation (SBT) in rats.Methods Three groups were set up: Group A (n=18), receiving sham operation and feeding of common feedstuff; Group B (n=18) receiving SD rat to SD rat iso-series SBT and the treatment of routine liquid infusion and antibiotics after operation; Group C (n=18) receiving SD rat to Wistar rat taniso-series SBT and the same post- operation treatments as in group B. Samples of grafts and peripheral blood in the three groups were collected on the day 3, 5 and 7 respectively after SBT for detection of flow cytometry. The intestinal grafts were obtained for pathological examination.Results The survival time of rats in group C, group B and group A was 7.0? 2.1, 33.3? 2.3 and more than 90 days, respectively. There was significant difference between group C and groups A, B (P

Objective:To compare the characteristics of pruritus after epidural and subarchoid morphine for postoperative analgesia. Method: One hundred and twenty patients after hysterectomy were randomly allocated to receiving subarchoid morphine 0.5mg(group Ⅰ,n=60)or epidural morphine 2 mg(group Ⅱ,n=60),respectively. The pruritus incidence, pruritus scale, time and site of occurrence were observed in both groups. Result: In group Ⅰ, the pruritus incidence of 87%,27% of pruritus scale being more than 2 and total pruritus scale being 8 (0-18) were significantly higher than those[31%, 12% and 6(0-14)] in group Ⅱ (P

The paper described efforts made by Guangdong province to achieve a goal of the healthcare reform Serious diseases can be treated within the county.In this reform,the province attempts such operation mechanisms as autonomous type,guided type and trusted type for the purpose of elevating the service capabilities of county-level public hospitals.To this end,four independent operation mechanisms have also been built for talent development,remuneration incentive,specialty development,and cost control.All these efforts aim at encouraging the hospitals to improve service capability and quality.

AIM: To affirm marker peaks for the fingerprint chromatography of Shengmai Injection. METHODS: LC-MS/MS method was used, with a Waters symmetryshield TM RP_ 18 column(4.6 mm?250 mm; 5.0 ?m), acetonitrile-water as a mobile phase, The detection wavelength was at 203 nm. Ion trap mass spectrum. RESULTS: Affirming marker peaks for fingerprint chromatography of Shengmai Injection and 10 marker peaks were affirmed. CONCLUSION: The method can affirm marker peaks for the fingerprint chromatography of Shengmai Injection. It is simple, accurate, and has practicality.

Objective To investigate the effects of metabolic syndrome (MS) and the cardiocerebrovascular risk factors such as essential hypertension (EH), diabetes mellitus (DM), and lipid metabolise disturbance on the subtypes of acute cerebrovascular disease (ACVD). Methods A total of 502 ACVD patients were studied, including 121 cases of intracerebral hemorrhage (ICH) and 381 cases of cerebral infarct (CI). The effects of MS, EH, DM, and blood lipids on the subtypes of ACVD were analyzed. Results The ratio of all subtypes of ACVD combined with EH was significantly higher than that of the control group ( P 0.05). Additionally, the concentration of total cholesterol in the ischemic group was significantly lower than that in the control group ( P

Objective To study the influence of climate, geographical environment and harvesting time on contents of schaftoside in Desmodium styracifolium Herba. Methods Content of schaftoside in Desmodium styracifolium Herba was determined by using HPLC. ODS-C18 column (4. 6 mmí250 mm,5 μm) was used, the mobile phase was methanol-water (3268), the detection wavelength was 272 nm, the flow rate was 0. 5 mL·min-1, and the column temperature was 35℃. Results The climate type, amount of precipitation, average temperature, duration of sunshine, geographical environment of different province had significant impacts on the content of schaftoside in Desmodium styracifolium Herba. Conclusion Subtropical monsoon climate, temperature from 25 ℃ to 32 ℃, sunshine time of 10 h per day and the average annual rainfall of 1 942 mm are suitable for growth of Desmodium styracifolium. The content of schaftoside in samples cultivated from Guangxi Province is higher than that cultivated from Guangdong Province and Hainan Province. The schaftoside content of sample cultivated in July is higher than that cultivated in other months.
