Objective:To study the functional status of the monocytes-derived dendritic cells (DCs) plused with HBsAg from patients with chronic hepatitis B and their capacity of inducing the HBV- special cytotoxic T lymphocytes (CTLs),and explore a new method of inducing the special anti-HBV cell-mediated immunity.Methods:Monocytes of patients were isolated from peripheral blood and incubated with GM-CSF+IL-4+TNF-? to induce DCs generation. Those DCs were pulsed with HBsAg to induce HBV- special DCs. The phenotype of DCs including CD1a,CD80,CD83,CD86,CD40 and HLA-DR was characterized by FCM and the stimulating reaction of allogenic T lymphocytes was detected by MTT assay. The concentration of cytokines such as IL-12 and IL-6 in supernate was tested by ELISA and the cytotoxicity of CTLs inducing by the DCs against HepG2 2.2.15 cells,HepG2 cells and K562 cells were detected by LDH assay.Results:The expression of CD1a, CD80, CD83,CD86, CD40, HLA-DR molecules on the DCs pulsed with HBsAg was higher than those of the control group (P

Diabetes is a kind of metabolic syndrome, always hap-pening in the case of insufficient secretion of insulin or insulin resistance, inducing the increase of blood glucose. While, dia-betic osteoporosis is a kind of chronic diabetic complications, which happens when insulin secretion is absolutely or relatively insufficient and then the insufficiency induces imbalance of hor-mone, calcium phosphorus metabolic disorders, thus leading to the decline of bone mineral density and change of bone micro-structure. The overnutrition, less exercise and the environment change lead to the increased incidence of diabetes. For all the diabetes, type 2 diabetes accounts for about 90%. Patients with type 2 diabetes show the increasing risk of fracture. This review summarizes the recent advances in the influence of type 2 diabe-tes on bones.

Objective To investigate the clinical and pathological features of gastric cancer with ovarian metastasis and to analyze the reasons for its misdiagnosis. Methods There were 52 cases of gastric cancer with ovarian metastasis who had pathologic diagnoses from Jan. 1990 to Jun. 2004, whose clinical datum, pathological classification and the reasons for misdiagnosis were reviewed retrospectively and analyzed. Results The average age of the patients was 40.15?1.28 ( the ages ranging from 22 to 64 ). These patients's first symptoms and signs often were a metastatic ovary cancer. The main ultrasonographic findings were either a complex type of mass with both solid and cystic characteristics or only solid one, most of which accompany hydroperitonia, and among them metastatic ovary tumors on both sides reached 76.9 %. The serum CA125 levels increased, amounting to ( 99.85?14.23)U/mL on the average. It was greatly lower than a primary ovarian cancer(P

Objective Acute respiratory dysfunction (ARD) can occur after aortic surgery with the use of cardiopulmonary bypass and deep hypothermic circulation arrest, but relatively little is known about acute respiratory dysfunction in the patients with type A aortic dissection. This study aims to analyze the independent risk factors of acute respiratory dysfunction after A type aortic dissection surgery and to assess possible prevention and treatment option in the future. Methods Clinical data of the 252 patients including 193 male patients and 59 female patients who underwent type A aortic dissection surgery from February 2009 to October 2010 were collected. The mean age was 47 years. Postoperative acute respiratory dysfunction was defined as oxygenation impairment (PaO2/FiO2 ＜ 150) that occurred within 72 h of surgery except pleural effusion, cardiogenic pulmonary edema, pneumonia, pulmonary embolism and haemato-/ pneumothorax. There were 187 acute A type aortic dissection patients and 65 chronic type A aortic dissection patients. Clinical characteristics including age, gender, weight, height, history of hypertension, history of smoking, preoperative complications such as preoperative shock and acute renal failure, pericardial effusion, previous cardiac surgery, time from event to surgery, malperfusion syndrome, cardiopulmonary time, cross-clamp time,deep hypothermia circulation arrest time, surgical procedure, duration of intensive care unit stay and postoperative complications including tracheotomy, dialysis dependent renal failure and hospital mortality were gathered. Arterial blood analysis, chest X ray, ventilator parameters, number of blood transfusion and flood balance were assayed after operation. All the factors were evaluated by means of univariate and multivariate logistic regression analysis to identify relative risk factors of ARD. Results Acute respiratory dysfunction occurred in 32 (12.7% ) patients. The in-hospital mortality was significant difference between acute respiratory dysfunction group and non- acute respiratory dysfunction group (P ＜ 0.05). The value of BMI, incidence of acute aortic dissection, preoperative SBP level, cardio-pulmonary bypass time, aortic clamp time and total arch replacement in acute respiratory dysfunction group were significantly higher than the values in non- acute respiratory dysfunction group. Multivariate Logistic regression analysis showed blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes were independent risk factors of early stage acute respiratory dysfunction after type A aortic dissection surgery.Conclusion Acute respiratory dysfunction after type A aortic dissection was a severe early stage postoperative complication and was associated with in-hospital mortality. The patients in acute aortic dissection were prone to have acute respiratory dysfunction. The independent risk factors of acute respiratory dysfunction included blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes.

Huoxue Tongmai Lishui method, a traditional Chinese medicine treatment for eliminating water, activating and promoting blood circulation, could inhibit fundus hemorrhage on experimental retinal vein occlusion (RVO) with high obvious effective rate, and improve symptoms in traditional Chinese medicine. The action mechanism may be related to reducing plasma viscosity and non-perfusion area, and the formation of collateral circulation.

ObjectiveTo evaluate the therapeutic effect ofZishen decoction combined with standard treatment of western medicine for for stage IV diabetic nephropathy with Qi and Yin deficiency.MethodsA total of 112 patients with stage IV diabetic nephropathy and Qi and Yin deficiency were randomized to thestandard treatment and the combined treatment groups, 56 in each. The standard treatment group received conventional treatment, including blood glucose controlling, antihypertensive, blood lipid regulating and diet controlling. The combined treatment group receivedZishen decoction on the basis of conventional treatment. All the patients were treated for 3 months. The blood urea nitrogen (BUN), serum creatinine (SCr), total cholesterol (TG), triacylglycerol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and glycated hemoglobin (HbA1c) were measured by an automatic chemistry analyzer. The urinary albumin excretion rate (UAER) was measured by the enzyme-linked immunosorbent assay.ResultsCompared with the standard treatment group, the SCr (53.51 ± 18.12μmol/Lvs. 62.66 ± 21.14μmol/L;t=2.459,P<0.05), UAER(100.73±84.24μg/minvs. 156.24 ± 96.38μg/min;t=3.245,P<0.05), TG(1.73±0.22 mmol/Lvs. 2.06 ± 0.21 mmol/L;t=8.112,P<0.01), TC(4.56 ± 0.62 mmol/Lvs. 5.10 ±0.31 mmol/L;t=5.830, P<0.01), LDL-C (2.42 ± 1.05 mmol/Lvs. 3.31 ± 0.81 mmol/L;t=5.022,P<0.01) in the combined treatment group decreased significantly, and the HDL-C (1.67 ± 0.33 mmol/Lvs. 1.36 ± 0.41 mmol/L;t=4.460,P<0.01) increased significantly. ConclusionZishen decoction on the basis of conventional treatment can improve the SCr and UAER, and regulate the blood lipid in the patients with stage IV diabetic nephropathy and Qi-Yin deficiency.

ObjectiveTo develop an antibody-array system for multiple detection of antibodies against Japanese B encephalitis virus (JEV),Tick-borne encephalitis virus (TBV),Dengue virus ( DENV ),West Nile virus (WNV),Western equine encephalitis virus (WEEV) and East Equine encephalitis virus (EEEV).MethodsRecombined antigens were spotted on array as capture antigens.Specific antibodies were detected by using a sandwich ELISA format.Rabbit antiserum was employed to select and confirm the specificity of antigens and to optimize the conditions of the assay.The detection efficiency of the system was validated by 40 clinical suspected serum samples and compared with the relative ELISA assays.ResultsEleven recombined antigens were selected as diagnostic antigens with high specificity.Better detection could be achieved when scale of antigen concentrations were within 0.125-0.900 mg/ml and the serum dilutions were 1:100-1:1000.When detecting the 26 clinical suspected TBE serum samples,20 were IgG positive (76.9％),and 17 were IgM positive (65.3％) which was 96.1％ and 84.6％ consistent with the relevant ELLSA tests,the 8 clinical suspected JEV serum samples,4 were IgG positive (50.0％),and 5 were IgM positive (62.0％),which was 86.3％ and 90.1％ consistent with the relevant ELLSA tests.As for the 22 DEN serum samples,13 were IgG positive (60％) and 15 were IgM positive (68％) which was 85％ and 93％ consistent with ELISA.The specificity of the assay was 100％ and the sensitivity was higher than the relative ELISAs.ConclusionThe developed antibody-array is highly specific and reliable,which could be used for the detection of antibodies against the 6 arboviruses.
