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.

Cloud computing possesses the great, safe and reliable ability to store data, implements the integration and sharing of information resources, and reduces the economic cost.The infringement risks of intellectual property in digital library under cloud computing environment were described , such as infringement risks of intellectual proper-ty due to cloud computing safety , direct and indirect infringement risks of intellectual property of cloud service pro-viders.Measures for how to prevent and control them were put forward in aspects of laws and administrations.

Exhaled nitric oxide fraction (FeNO)reflects eosinophilic bronchial inflammation,and has been widely used to assist in the diagnosis of asthma,to monitor the airway inflammation and the responce to treatment effects of asthma in recent years.FeNO as a noninvasive examination,obtains a high degree of cooperation in adults and children over 5 years of age,but there are a lot of problems in children under 5 years of age.At present,there is still a lack of normal values and large sample-sized studies of FeNO in infants and neonates in China.The principle and method,normal reference value,influencing factors,clinical application and so on of exhaled nitric oxide detection are reviewed in this paper.

Objective To observe the clinical efficacy of ear acupuncture combined with mirtazapine in the treatment of insomnia.Methods Sixty-two patients with insomnia diagnosed by CCMD-Ⅲ were randomly divided into two groups,31 patients in each group.The patients in the observation group were treated by ear acupuncture combined with mirtazapine,and the patients in the control group were treated by mirtazapine.The clinical efficacy was evaluated by SDRS after 4 weeks of treatment.Results The SDRS score of the observation group significantly decreased after one week of treatment [(13.40±5.79)points vs.(21.79±6.12)points,t=2.204,P＜0.05].The SDRS score of the control group significantly decreased after one week of treatment [(14.68±5.88)points vs.(22.67±6.06)points,t=2.198,P＜0.05].After 4 weeks of treatment,the clinical efficacy of the observation group was significantly better than that of the control group (z=-2.209,P＜0.05),the SDRS score of the observation group was also significantly better than that of the control group (t=2.163,P＜0.05).Conclusion Ear acupuncture combined with mirtazapine has better effect in the treatment of insomnia patients,it has less side effects and lasting effects.

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.

Objective To evaluate the value of digital subtraction angiography(DSA) in diagnosis and planning endovascular treatment of cerebrovascular diseases. Methods Thirty-one children suspected with ischemic cerebrovascular diseases were treated by urokinase and dextran after they underwent DSA.Results Twenty-four cases (77%) had cerebrovascular abnormalities. Two cases had arteriovenous malformations, 1 case had posterior communicating artery aneurysm,21 cases had cerebrovascular stenosis or occlusions. Shortly after intervention therapy using urokinase,muscle strength increased by one level in 13 cases,two levels in 3 cases,3 levels in 2 cases and no effect in 4 cases. The total effective rate reached 86%. Seven patients with ischemic stroke achieved 100% recanalization. Conclusion DSA is very important in diagnosis of cerebrovascular stenosis and occlusion.

OBJECTIVE: To discuss advances in intrahepatic and intrabiliary stent application and evaluate their biocompatibility.METHODS: A computer-based online search of CNKI between 1989 and 2009 was performed to search related articles with the keywords of "bile duct, hepatic duct, stent, treatment". A total of 51 articles were searched and 20 were included according to inclusion and exclusion criteria. The articles were summarized from aspects of treatment advances in intrahepatic and intrabiliary stent application and prevention of obstruction following intrahepatic and intrabiliary stenting; the clinical application of intrahepatic and intrabiliary stent, biocompatibility and prevention of stent obstruction were discussed.RESULTS: Intrabiliary stent mainly includes metal stent and plastic stent. The metal stent is superior over plastic stent in preventing bacteria and keeping stent patency, but its cost is large. The plastic stent is easy for bacteria attachment and stent obstruction, but it is simple to change the stent and the cost is low. Intrabiliary stent implantation is the best method to treat malignant obstruction of bile duct with few complications. Intrahepatic stent in combination with various radiotherapies can prolong effective patent time of the stent and effectively prevent stent obstruction. CONCLUSION: Intrabiliary stent implantation is the most effective clinical method to treat malignant obstruction of bile duct.However, the biocompatibility of various intrabiliary stents should be improved. Intrahepatic stent in combination with radiotherapies can prevent stent obstruction.
