Objective To compare the level of Annexin Ⅱ in patients with systemic lupus erythematosus(SLE),diabetic nephropathy(DN),chronic glomerulonephritis and normal controls,and explorle the significance of the annexin Ⅱ in SLE.Methods Thirty-five cases of patients with SLE,ten cases of patients with DN,ten cases of patients with chronic glomerulonephritis were enrolled in this study,twenty cases of healthy controls were also enrolled.Circulating annexin Ⅱ in white blood cells was detected bv flow cytometry.Student's t test,variance analysis and Lineat correlation analysis were used for statistial analysis.Resuits Compared with healthy controls,the level of annexin Ⅱ in white blood cells in SLE patients (7.1±2.9)%and DN patients(8.0±3.7)%were significantly lower than that of the healthy controls(P<0.01,p<0.05).In the SLE group,the level of annexin Ⅱ of patients who had more active disease(SLEDAI≥9)decreased more thall those with less active disease(SLEDAI<9),(P<0.05).A positive correlation was found between annexin Ⅱ and serum albumin level(r:0.439,P<0.01),but negative correlation was found between annexin and urine protein/urine creatinine(r=-0.382,P<0.05),SLEDAI(r=-0.417,P<0.05),D-dimer(r=-0.336.p＜0.05) levels.Conclusion The level of annexin Ⅱ is decreased in patients with SLE,so it can renectthe abnormality of coagulation and fibrinolytic systems,and it may be used as a good indicator for prothrombotic status in SLE patients.It can be helpful to evaluatethe activity of the disease and the therapeutic efficacy.

Objective To detect the methylation status of the promoter of BNIP3 gene in gastric cancer cell lines MKN1,and to explore the mecha?nism of DNA methylation regulating the expression of BNIP3 in gastric cancer cells. Methods The methylation status of BNIP3 promoter was de?tected by bisulfate sequencing PCR. Reverse transcription PCR was used to evaluate BNIP3 mRNA expression. MKN1 cells were treated with 5?Aza?2′?deoxycytidine(5?Aza?CdR),and after the treatment,the methylation status and BNIP3 mRNA expression were observed. Chromatin immuno?precipitation(ChIP)was used to determine the combination of BNIP3 with DNA methyltransferase 1(DNMT1). Results The promoter DNA of BNIP3 in MKN1 cells was in state of hypermethylation. Compared to the control group,methylation status and mRNA expression of BNIP3 in the drug treatment group(the 5?Aza?CdR concentration was 10μmol/L)were reversed,which showed statistical differences(P<0.05). 5?Aza?CdR inhibited the combination of BNIP3 with DNMT1. Conclusion CpG island methylation regulates BNIP3 gene expression in MKN1 cells. DNA methylation is related with the binding between the promoter of BNIP3 and DNMT1.

Objective To summarize the clinical characteristics,diagnosis and treatment of pulmonary sequestration(PS) in children.Methods The clinical data of 19 children with PS confirmed by operation and(or) imaging examination from Mar.2003 to May.2008 were analyzed retrospectively.Thirteen cases were male,and 6 cases were female.One case was newborn infant.Seventeen cases received operation.Intralober type had a pulmonary lobectomy and extralobar type had a sequestrectomy.Chest X-ray and CT scan examinations were performed on the patients before operation.Results Seventeen cases got complete cure by operation,and the mean age at operation was 5.2 years.Chest enhanced CT indicated abnormal feeding arteries.Lobectomy was performed in 13 cases of intralobar PS,4 cases of extralobar PS were resected in the separated lung tissue,and all patients had unilateral lesions.No late deaths occurred in this group except 1 case who was complicated with malformation,and the postoperative follow-up showed an excellent recovery.Conclusions The main diagnostic methods of PS are CT and angiography.The diagnosis of PS can be confirmed when systemic feeding arteries are indicated on enhanced CT scans.Surgical resection is the main choice of treatment in all cases of PS in order to prevent recurrent infection and hemoptysis.The excellent results can be obtained by surgery.

Objective To compare the effects of telmisartan and (or) amlodipine on the reversal left ventricular re-modeling in two-kidney one clip hypertensive rats. Methods A total of 50 healthy male SD rats were randomly divided into 5 groups (n=10):two-kidney one clip renal hypertensive (2KIC) model group, sham group, telmisartan (10 mg/kg) group, am-lodipine (2.5 mg/kg) group and telmisartan (10 mg/kg)+amlodipine(2.5 mg/kg) group. The model of two-kidney one clip re-nal hypertensive rats was established. The tail arterial blood pressure was detected once a week. After 20 weeks, rats were sacrificed and specimens were collected. The left ventricular mass index (LVMI) was assessed. The myocardial ultrastructur-al changes were observed by electron microscope. Values of plasma renin activity (PRA), angiotensionⅡ(AngⅡ) and atrial natriuretic peptide (ANP) were measured by enzyme linked immunosorbent assay (ELISA).Results Compared with sham group, the levels of systolic blood pressure (SBP), LVMI, PRA, AngⅡand ANP were significantly higher in 2KIC group (P＜0.01). Compared with 2KIC group, values of SBP, LVMI, PRA and ANP were significantly lower in telmisartan group and am-lodipine group (P＜0.01), but the value of AngⅡwas significantly higher (P＜0.01). The levels of SBP, LVMI, AngⅡand ANP were significantly lower in combined medication group than those of single drug medication group (P＜0.01). There was no significant difference in the plasma PRA level between those groups (P>0.05). Results of myocardial electron microsco-py showed that the left ventricular remodeling was significantly improved in combined treatment group. Conclusion Telmisartan and amlodipine can effectively improve the left ventricular remodeling induced by hypertension. There was more effective therapy using both medications together.
