Helicobacter pylori(Hp)infection is associated with many kinds of upper gastrointestinal diseases,and is also associated with some extragastric diseases. Hp eradication can cure peptic ulcer or reduce the risk of recurrence, inhibit the development of chronic atrophic gastritis,and decrease the risk of gastric carcinoma. Antibiotic resistance is the main cause of treatment failure of Hp eradication. Other factors,such as host,environment,co-existing diseases,and treatment regimens may also affect the results of Hp eradication.

Objective To assess the ability of the new software SonoAVC to measure follicular volume and to compare these volume calculations with those made by conventional methods. Methods Three-dimensional ultrasound imaging was used to acquire volumetric data from the ovaries of 50 women undergoing controlled ovarian stimulation as part of in-vitro fertilization treatment. SonoAVC was used to automatically measure the volume of follicles and virtual organ computer-aided analysis(VOCAL) was also applied to measure volume, which was used as the standard of volume measurement. And the three perpendicular diameters (xyz diameters) of follicles were manually measured by conventional two-dimensional(2D) ultrasound, which were used to estimate volume using the sphere formula. And the validity of each technique was compared using limits of agreement. Results One hundred and seventy-six follicles were studied. SonoAVC and VOCAL provided highly accurate and repeatable follicular volume measurements in all cases. Volumes estimated from manually derived follicular diameter measurements were less accurate and repeatable. VOCAL took more time in follicular volume of measurement than SonoAVC and conventional 2D displays. Conclusions SonoAVC provides highly accurate, repeatable,and efficient measurements of follicular volume.

To management of syncope in children and adolescents,the primary objectives are etiological diag-nosis and risk stratification.The possible causes for syncope ranging from relatively benign conditions to potentially life -threatening events.The efficient methods of diagnosis and risk stratification are vital important to identify those syncope patients who are at short -term or long -term risk of life -threatening events,avoiding unnecessary hospitali-zation of low -risk patients.In recent years,there came up with a multitude of quantitative methods in diagnosis and risk stratification,according to clinical history and physical exam and 1 2 -lead electrocardiograph.These methods can assit front -line physicians do an optimal decision -making,especially providing valuable guidance to make a well -in-formed choice between hospitalization and outpatient referral.Nevertheless,these existing methods can not replace criti-cal assessment by an experienced physician.

Aim To study the protective effects of curcumin on myocardial reperfusion injury in rats.Methods Myocardial ischemia reperfusion injury model was established through occluding the left anterior descending branch of coronary artery for 60 min and removing the ligation later to reperfuse for 30 min in vivo.Different doses of curcumin were administered through intravenous injection 5 min before the onset of ischemia.The changes of hemodynamics were recorded and myocardial infarct sizes were measured.Results Curcumin(20,40 mg?kg~(-1))improved the hemodynamics during myocardial ischemia reperfusion in a dose-dependent manner,as shown by the significant increase in LVSP and?dp/dt_(max) and the decrease in LVEP.Moreover,curcumin reduced the myocardial infarct sizes.Conclusion Curcumin exerts protective effects on myocardial ischemia reperfusion injury.

In this study, the expression of IL-24 at maternal-fetal interface and the roles in extravillous trophoblast (the TEV-1 cell line) invasion were examined. Immunohistochemistry was used to detect the expression of IL-24 in villi and decidual tissue. The proliferation of TEV-1 cells under the effect of IL-24 was measured by MTT assay. The invasiveness of TEV-1 cells under the effect of recombinant IL-24 (rhIL-24) was examined by transwell system. Immunohistochemical detection showed that IL-24 was expressed in the villi and decidual tissue, and distributed in villous column, trophoblasts, stroma and blood vessels. The proliferation of TEV-1 cells was not inhibited by rhIL-24 of various concentrations. The examination of invasion in vitro showed that rhIL-24 could inhibit the invasion of TEV-1 cells in a concentration-dependent manner. The results suggested IL-24 could inhibit the invasion of TEV-1 cells. Therefore, IL-24 produced by maternal-fetal interface in human first trimester pregnancy may influence the invasion of trophoblasts and is involved in normal pregnancy.

Object To prove the feasibility of bacterial endotoxin test (BET) in Shenmai Freeze-dried Powder Injection by interference test. Methods Interference primary screening test and interference test were conducted in BET of Shenmai Freeze-dried Powder Injection to detect whether the interference existed or not and to explore the method of removing the interference. Results There was inhibition on BET with 0.5 EU/mL tachypleus amebocyte lysate (TAL). Interference could be excluded by using 0.25 EU/mL TAL and diluting the samples. Conclusion It is feasible to use 0.25 EU/mL TAL or TAL with more sensitivity in BET of Shenmai Freeze-dried Powder Injection.

Over the past decade , with the rapid increase of the incidence of idiopathic membranous nephropathy (IMN) in our country, the diagnosis and treatment of IMN has been paid more and more attention.IMN is an autoimmune disease.Two important podocyte autoantigens , PLA2R and THSD7A, have been indentified sine 2009.Subsequently , serum anti-PLA2R antibody test and anti-THSD7A antibody test have also been used in clinical .Preliminary applications show that these two tests can not only help IMN diagnosis and differential diagnosis , but also help IMN prognosis.
