Objective:Apoptosis inhibitor 6(Api6),also known as AIM(Apoptosis Inhibitor expressed by Macrophage)or SP?(Soluble Protein alpha),is a newly defined member of the group B scavenger receptor cysteine-rich(SRCR)superfamily.Previous studies have suggested its important roles in immune system regulation,but the involvement of Api6 in lipid metabolism is seldomly studied.Methods:The aim of this study was to define the expression pattern of Api6 in lipid loading and inflammatory macrophages.The human monocyte/macrophage lineage THP-1 cells and murine Raw264.7 macrophages were incubated in the presence of 100 ?g/ml oxidized low-density lipoprotein(oxLDL)alone,LDL plus 200 ng/ml lipopolysaccharide(LPS)and LPS alone.Results:Foam cell formation after treatment was evidenced by oil red O staining.Real-time PCR results showed that after LPS or oxLDL treatment,the mRNA levels of Scavenger receptor SRA were increased 6-fold,2.5-fold and 6-fold,44-fold in Raw264.7 cells and THP-1 cellls respectively,but the expression of Api6 in Raw264.7 did not change.The mRNA levels of Api6 increased 2.7-fold after LPS and oxLDL treatment in THP-1 cells.Conclusion:The expression levels of Api6 in these macrophages were highly related to the presence of nuclear receptor liver X receptor(LXR)isoform LXR?.This study revealed that due to the lack of LXR? isoform,the basic expression level of Api6 was low in Raw264.7 macrophages,that makes it an ideal cell line for further study related to pathophysiological function of Api6 in lipid metabolism.

Objective To investigate the relationship between plasma N-terminal pro brain natriuretic peptide(NT-proBNP) level and left ventricular(LV) diastolic dysfunction in hypertensive patients without systolic dysfunction.Methods Forty-four cases of primary hypertensive patients with left ventricular ejection fraction more than 50％ were enrolled,14 cases in normal diastolic function group,30 cases in diastolic dysfunction group(18 cases in delayed relaxation group and 12 cases in pseudo normalization filling group).LV diastolic function was assessed with conventional Doppler by means of mitral inflow and with tissue Doppler echocardiography by means of mitral annulus.The ratio of early diastolic transmitral E wave velocities to tissue Doppler mitral annulus early diastolic E' wave velocities (E/E') was used to detect LV filling pressures.Patients were divided into three groups according to E/E' ratios.Plasma concentrations of NT-proBNP were also measured.All related data were statistically analyzed.Results The levels of NT-proBNP were (115.2 ± 78.9)ng/L in LV diastolic dysfunction group,(34.7 ± 17.5) ng/L in normal filling group and (206.6 ± 75.8) ng/L in pseudonormal filling group.The level of NT-proBNP significantly elevated (F =85.263,P =0.000) along with the severity of lefi ventricular diastolic dysfunction.There was significant difference between each of the two groups among the three groups(all P ＜0.01).According to E/E' ratios,the patients were divided into three groups:E/E' ＜10(n =16),10 ＜ E/E ＜ 15(n =18),E/E' ＞ 15(n =10).The level of NT-proBNP were (39.5 ± 20.1) ng/L,(71.2 ± 26.4) ng/L and (203.7 ± 75.2) ng/L respectively in the three groups.The NT-proBNP blood level was positively correlated significantly with E/E' ratio (r =0.80,P ＜ 0.01).The sensitivity was 87％ and the specificity was 100％ for diagnosis of left ventricular filling pressure (E/E' ＞ 15)according to a NT-proBNP value of 119 ng/L.Conclusion Combining of plasma NT-proBNP and Doppler E/E'have potential value for identification of those patients with hypertension to detect early cardiovascular changes,especially LV diastolic dysfunction.

BACKGROUND:Studies demonstrated that matrix metalloproteinase-1(MMP-1) and tissue inhibitor of metalloproteinases-1(TIMP-1) exhibit important role in corneal defect of rats with alkali burns.OBJECTIVE:To observe the promoting effect of recombinant human epidermal growth factor(rhEGF) on rats' corneas following alkali burns,in addition,to explore the effect and significance of rhEGF on the expression of MMP-1 and TIMP-1 in alkali burned rats.DESIGN,TIME AND SETTING:A randomized controlled animal experiment was performed at the Laboratory Animal Center,Liaoning Medical College from March 2008 to May 2009.MATERIALS:Sixty healthy SD rats,weighting 180-210 g,with 6-8 weeks old,half male and half female.All rats were confirmed that no anterior segment disease before the experiment with slit lamp microscope examination.METHODS:Sixty rats were randomly divided into experimental and control groups,with 30 animals in each group.After the preparation of corneal alkali burn models,cornea of rats in the experimental and control groups were given rhEGF eye drops,and physiological saline eye drops respectively,fourth a day,consecutive for 21 days.Six rats of each group were killed at days 1,4,7,14 and 21 after operation.MAIN OUTCOME MEASURES:①Changes of cornea after alkali burned was observed by slit lamp microscope.②The expressions of MMP-1 and TIMP-1 in cornea were detected with immunohistochemistry and computer image analysis system at different time points.RESULTS:The slit lamp microscope results showed that the area of corneal ulcer in the experimental group was obvious smaller than the control group at the corresponding time points.The expression of MMP-1 gradually increased and reached a peak level at 14 days after surgery,then began to decrease.TIMP-1 expressed in the early phrase,but later,its activity gradually decreased,reached the lowest level at 14 days,then began to increase,and peaked at 21 days.The level of MMP-1 in the experimental group was greatly lower than that in the control group at each time points.However,the level of TIMP-1 of the experimental group was greatly higher compared with the control group.CONCLUSION:The rhEGF eye drops can improve effectively the healing of corneal epithelial defect by adjusting the proportion of matrix metalloproteinase and its tissue inhibitor.

Objective To study the process of the root development of Codonopsis pilosula as well as theaccumulatinglocationsofthemainmedicinalcompositionandstoragenutritionintheroot. MethodsThe development process of the roots was studied by paraffin section methods. Storage nutrition was loca-lized by PAS reaction and Sudan Ⅲ reaction. The medicinal composition of C. pilosula, terpene and steroid were stained with mix reagent of 5% vanillin-acetic acid and perchloric acid. Results The development process of the root is shown as four stages: promeristem, primary meristem, primary structure, and secondary growth. Abundant laticifers exist in mature root and the prime laticifers could be found in phloem as early as the first vessel of primary xylem appears. Then, the laticifers exist in phloem at all time. Starch granule accumulated in mature root as reserved substance. Terpene and steroid accumulated in parenchyma and laticifer. Conclusion Parenchyma and laticifer in the roots of C. pilosula are the main parts of the roots to store medicinal composition and storage nutrition.

It is a simple and reliable surgical approach for correction of epicanthus.

Mycoplasma, Chlamydia, Rickettsia, Spirochetes and Actinobacteria were generally called "four pathogens and one bacterium". It was always difficult to be denominated and classified rightly in textbooks, while it was also a key interfering with students to grasp the concept of bacteria exactly. So we raise the question and hope to learn from each other by an exchange of views here.
