0 05)and the consistence rate of 3 000 sera tested by two methods were 99 4% totally, including 99 8%(mixture of speckled and homogeneous), 99 5%( homogeneous) and 99 0%( speckled), respectively Conclusion The difference of ANA results between laboratory caused by test condition such as fluorescence microscopy could be eliminated by using quality control with known fluorescence density So the ANA results may be more precise, reliable and comparable We could, thereby, holisticly improve the quality of ANA detection

Objective To study and design a fluid resuscitation control system which is suitable for the treatment of hemorrhagic shock in the battlefield and prehospital settings. Methods The physiological parameters of the wounded were set as the system input and fuzzy control technology was used to identify the hemorrhagic shock (HS) severity and made a decision. At last, fluid resuscitation was finished with the use of the efficient blood transfusion and infusion pump. Results High-speed resuscitation could be carried out when the wounded was in severe condition, while low-speed resuscitation could be conducted when the wound was in mild condition. Conclusions Compared with the traditional resuscitation method, the designed fluid resuscitation control system can improve the efficiency of fluid resuscitation and the treatment success rate.

In this paper,the educational mode of master of public health (MPH) in America and China were reviewed through literatures searching and internet searching and the difference between America and China were compared from the sources of students,students' characters,educational objective,specialties and curricula,methods of teaching and management.There is still a certain gap in education of MPH in China.The educational mode needs optimizing with changing enrollment methods,definitude training objectives,perfect curriculum setting,increased opportunities for practice and strict quality control,so that the educational mode of MPH will be perfected in China.

Objective To investigate the level of five auto-antibodies including MCV and GPI in the serum of RA patients and assess the application value of five auto-antibodies in RA diagnosis.Methods The five auto-antibodies were detected by ELISA in serum samples of 150 patients with RA and 40 healthy controls,32 patients of SLE,30 patients of OA,20 patients of AS,20 patients of SS,20 patients of CTD.Results The positive rates of these five auto-antibodies in RA patients were significantly higher than in other group(X2=88.5,76.0,279.2,88.2,94.8,P＜0.05).Except anti-AKA,there was no the differences in the level of other antibodies among groups(X2=21.9,9.4,20.2,43.2,41.6,P＞0.05).Anti-MCV and anti-GPI has the highest sensitivity(78.0% and 83.3%),while anti-CCP has the highest specificity(97.1%)and anti-AKA has good specificity(96.1%)and lowest sensitivity(49.4%).When two antibodies were detected together,the sensitivity and specificity of MCV/CCP were highest(92.7% and 96.9%).When RF/GPI/CCP were detected together,the sensitivity and specificity were 90.7% and 96.9%,respectively.When RF/MCv/CCP were detected together,the sensitivity and specificity were 94.0% and 96.9%.Conclusions Anti-MCV and anti-GPI has the hishest sensitivity in laboratory diagnosis of RA,while anti-CCP has the highest specificity and anti-AKA have good specificity and lowest sensitivity.The combination detection can decrease the amount of missed diagnosis caused by single test. The combination detection of RF/GPI/CCP and RF/MCV/CCP will improve sensitivity and specificity for diagnosis to the RA patients.

This study was firstly conducted to detect antinuclear antibody(ANA) titer by using number influorescence density analysis assay instead of serum diluted assay. The best camera explore time was selected. Then 4,140 ANA positive sera were detected to determine the relationship between number influorescence density (detected by number camera system Spot 32 and computer analysis software ipwin32) and serum diluted titer. The consistent rates in different ANA patterns used by the two methods were compared. 4 seconds was found to be the best explore time and the relationship between number influorescence density and serum diluted titer was 29-50 vs 1:100, 51-85 vs 1:320, 86-175 vs 1:1000, 176-215 vs 1:3200, 216-237 vs 1:10,000. According to this standard we detected 3140 ANA positive sera by use of the two methods and observed a total consistency rate of 89.4%. The consistency rates of three ANA patterns including speckled, homogenous, mixture of speckled and homogenous were as high as 98.9%, 99.5%, 99.8% respectively. The lower consistency rate patterns included nucleolar (5.3%), centromere (1.8%), ribosome(12.6%) and other special patterns(0%). For practical purpose, number influorescence density analysis assay can be used in detecting the three main ANA patterns (speckled, homogeneous, mixture of speckled and homogenous) titer instead of serum diluted assay. The number influorescence density analysis assay is more objective, economical and simple than the serum diluted assay.

Objective To obtain the data of injury among children aged 0~6 years in Haidian area and Pinggu area of Beijing.Methods A total of 2970 children aged 0~6 years in Haidian District(city area) and 2558 in Pinggu District (rural area)were investigated by cluster sampling method.Results A total of 5528 children were investigated,the incidence of injury was 8.64%.The incidence rate of aged 0~6 years child injury in Haidian District was10.54%,which was much higher than that in Pinggu District (6.45%).The top five causes of injury were falls,animal bites,burn/scalds,injury by sharp articles and struck/hit by falling object in Pinggu District.The top five causes of injury were falls,animal bites,injury by sharp articles,burn/scalds and blunt in Haidian District.the sequences of injury were similar between the two districts.The incidence rate of burns/scalds was higher in Pinggu District than that in Haidian District.The types of injury were little different between children who lived at home and children who lived in kindergarten.The types of injury were not too different between genders.Falls was the leading cause of injury for all children(in cities or in countries,boys and girls,in different age group).Conclusion The incidence rates of injury and types of injury are different in different areas,genders and age groups.So the intervention of injury should be different.

This article reported the comprehensive management of an extremely preterm infant with severe bronchopulmonary dysplasia. The patient born at 26 +6 gestational weeks was transferred to Children's Hospital of Fudan University due to invasive mechanical ventilation dependence at 61 d after birth and was diagnosed with severe bronchopulmonary dysplasia. A comprehensive treatment plan was adopted, including appropriate fluid restriction, improving nutrition, glucocorticoid administration, using antibiotics against Ureaplasma urealyticum infection to reduce pulmonary parenchymal lesions and alleviating pulmonary hypertension. The preterm infant was successfully extubated to non-invasive ventilation and subsequently weaned to a high-flow nasal cannula. Then, the patient was discharged at 372 d after birth (correct gestational age nine months and six days). At the 3-month follow-up after discharge, the patient remained on high-flow oxygen, but with lower flow and concentration of oxygen. Moreover, the growth, development and lung images were significantly improved. Follow-up to correct gestational age one year and 11 months, the child was not on oxygen any more, but on rehabilitation due to language and motor development retardation.

AIM: To investigate the pharmacokinetic properties of the main active components of Dalitong extract in SD rats after oral administration using UPLC-MS / MS. METHODS: An UPLC-MS / MS method was established to simultaneously detect tetrahydropalmatine, nobiletin and costunolide in the plasma and tissues of SD rats. The method was applied to investigate the pharmacokinetic characteristics and tissue distribution. RESULTS: After a single oral administration, the three active components were rapidly absorbed into the body, with a peak concentration (Cmax) of (13.73 ± 7.50), (27.01 ± 17.69) and (6.73 ± 29.94) ng / mL for tetrahydropalmatine, nobiletin, and costunolide, respectively. The time to reach the peak concentration (Tmax) was (1.40 ± 0.93), (0.63 ± 0.28) and (2.38 ± 8.81) h, respectively. The area under the curve (AUC) was (80.43±40.03), (41.30±28.69) and (303.90 ± 136.69) ng · h · mL
