AIM:To observe the effect of supplementing bilirubin on the anti-oxidative stress ability of red cell membrane in training rats through establishing animal models of high-intensity training. METHODS:The experiment was performed in the physiological laboratory of Physical Institute of Jiangxi Normal University from December 2004 to January 2005.①After one week of adaptive feeding,24 male SD rats were randomly divided into quiet control group,high intensity sports training and physiological saline group(training group),high intensity sports training and bilirubin group(training and supplementing group)with 8 animals in each group.②The training group and the training and supplementing group did the running on the platform with the slope of 0?at the first three weeks and 5?at the fourth week,6 days every week expect Sunday.The training and supplementing group was intragastrically infused with bilirubin by 40mg/kg body mass at 17:00-18:00 after training every day,and the other groups were given physiological saline,six times every week.Anticoagulatory blood about 2mL of heparin was harvested to prepare red cell membrane sample and measure the relevant indexes on the 4~(th)Sunday.③The serum total bilirubin level was determined using automatic biochemical analysis instrument;the malondialdehyde(MDA)and glutathione peroxidase(GSH-Px)of red cell membrane by TBA;the activity of superoxide dismutase(SOD)of red cell membrane using the method of Xanthine oxidase.All the treatment for animals was based on the ethical standards. RESULTS:All 24 rats were involved in the result analysis.①The serum total bilirubin level in training group was lower than quiet control group(P0.05).②The MDA of the red cell membrane in the training group was higher than the control and training and supplementing group(P0.05).③The activity of SOD in training group was lower than quiet control group(P0.05),but the training and supplementing group was higher than the control group and the training group(P

0.05 ).②The level of serum IgG increased in Gln group and maintained unchanged in control group.The level of serum CRP decreased more in Gln group than in control group( P

AIM This paper reviews methods of establishing experimental animal models of implantation failure and their observing index METHORDS Pregnant animals were instilled subcutaneously mifepristone, linorpristone, indomethacin,oxytocin or antiserum to ovine FSH, given pregnancy preventing wine to stomach or intrauterine injection of antibody to fibronectin and lamin RESULT The number of imbedded,implantation site and implantation rate of mice was reduced. The number of luteam on ovary was dimimished. Serum progesterone and chorionic gonadotropin levels were significantly decreased CONCLUSION The above methods could establish animal models of implantation failure

The analysis of 2013 circulating foreign and Chinese books in Library of Capital Medical University showed that the number of foreign and Chinese books classified into R Medicine and Healthand I Literaturewas the largest ,which thus provided the evidence for book acquisition ,book circulation and library holding develop-ment.Certain suggestions were put forward for improving the utilization of books, such as enforcing the acquisition and catalogue , and recommending books that should be bought .

BACKGROUND:Bone morphogenetic protein 9 is proved to promote the osteogenic differentiation of various kinds of stem cel s, but whether it can induce the osteogenic differentiation of dental fol icle cel s in vitro is yet unclear. OBJECTIVE:To investigate whether bone morphogenetic protein 9 can induce the osteogenic differentiation of rat dental fol icle cel s in vitro. METHODS:Purified rat dental fol icle cel s at passage 3 were transfected with bone morphogenetic protein 9 adenovirus. Then, alkaline phosphatase activity, calcium deposition and expression of osteogenesis-related factors at mRNA and protein levels were detected in the dental fol icle cel s. RESULTS AND CONCLUSION:After transfection with bone morphogenetic protein 9, the dental fol icle cel s showed continuously enhanced alkaline phosphatase activities and obviously enhanced calcium deposition. Real-time PCR results demonstrated that the mRNA expressions of alkaline phosphatase, osteocalcin, bone sialoprotein, osteopontin and core binding factor were increased significantly. The western blot assay showed that the expression of osteopontin enhanced in the dental fol icle cel s after transfection with bone morphogenetic protein 9. In summary, bone morphogenetic protein 9 can induce the osteogenic differentiation of dental fol icle cel s.

Sepsis is still a major cause of death among neonates and its morbidity rate remain high nowadays.Because of the atypical symptoms and extremely dangerous progress in neonatal sepsis,early diagnosis and treatment are requisite.But the unique biomarkers are lacking meanwhile.Recent study shows that PBEF influences individual susceptibility,severity and outcome in sepsis.This review synthesizes the research of PBEF in neonatal sepsis in order to provide the evidence of reliable biomarker to diagnose and treat neonatal sepsis in the early stage.

Based on reviewing briefly the development of the general education both in China and United States,selecting respectively a university as the example,the article has analyzed comparatively curriculum programs of general education between the two schools.Aimed at existing problem,from curriculum content carding,structure optimizing,teaching operating and evaluation of the effect,the article has proposed new thinking of reform on the general education of higher institutions.

Background:Psychological factor plays an important role in the pathogenesis of functional gastrointestinal disorders. Depression,anxiety may share the pathogenesis with irritable bowel syndrome( IBS),therefore,more and more attention has been paid to anti-depression and anti-anxiety in the treatment of IBS. Aims:To evaluate the effect of addition of flupentixol and melitracen tablets on IBS with depression and anxiety. Methods:Sixty IBS patients with depression and anxiety were randomly divided into control group and treatment group. Patients in control group were given live combined Bacillus subtilis and Enterococcus faecium enteric-coated capsules and trimebutine maleate,while paitents in treatment group were received flupentixol and melitracen tablets in addition to the above-mentioned medicine. Treatment course was 8 weeks. Hamilton depression scale,Hamilton anxiety scale and symptom score were evaluated before and after treatment. Results:Compared with control group,depression and anxiety in treatment group were obviously improved(P<0. 05);the relief rates of abdominal pain and diarrhea were significantly increased( P <0. 05 );and the total symptom score were significantly decreased(P<0. 05);the total effective rate was significantly increased(93. 3% vs. 76. 7%,P<0. 05). However,no significant difference in incidence of adverse reaction was found between the two groups. Conclusions:Additon of flupentixol and melitracen tablets can significantly improve the curative effect on IBS with depression and anxiety.

Objective:To review year 1956-2007 literature on acupuncture and moxibustion and explore the regularity of point selection and methods for acupuncture-moxibustion treatment of lumbar intervertebral disk herniation.Methods:A comprehensive analysis was made by a method of metrological analysis according to the data fromChina modern acupuncture-moxibustion information databank.Results:Points Huantiao(GB 30),Weizhong(BL40),Yanglingquan(GB 34),and Jiaji(Ex-B 2)were most frequently used.Acupuncture was the most frequently used thempy and electroacupuncture,the next one.Conclusion:Electroacupuncture is a common and effective Wav to treat lumbar intervertebral disk herniation.Points Huantiao(GB 30),Weizhong(BL 40),Yanglingquan(GB 34),and Jiaji(Ex-B 2)can be used as a basic prescription for acupuncture-moxibustion treatment of lumbar intervertebral disk herniation.Other acupoints are selected according to the syndrome.
