Objective To explore the Influence of different health education approaches to standard anticoagulation of non-valvular atrial fibrillation. Methods 400 patients with NVAF were randomly divided into the research group (n=200) and the control group (n=200). Baseline clinical information was recorded. Both groups were given regular education and treatment. The control group was randomly divided into two subgroups. One subgroup (patients or/and family members) was given knowledge lectures of atrial fibrillation, atrial fibrillation anticoagulant, and application of warfarin. The other was given the knowledge through booklets. Standard anticoagulation fulfillment rate, ischemic stroke, other events of artery embolism, major bleeding, minor bleeding and death in the two groups were observed after 1 year. The cost for different education approaches was also compared between the 2 subgroups. Results (1)In the research group, standard anticoagulation fullfillment rate (40.53%) was higher than that of the control group(15.96%) (P<0.01). The rate of ischemic stroke (2.63%) was also lower than the control group (4.49%) (χ2=4.49, P<0.05). The death rate was lower in the research group than those in the control group, but minor bleeding rate was higher, without statistically significance (P>0.05).Other artery embolism rate , major bleeding, minor bleeding, death rate had no statistical difference. (2)Knowledge lecture group (10.8±1.0 min) spend more time than the booklet group (1.0±0.5 min) (P<0.01). The booklet group (5.1±1.1 yuan) costed more in terms of money than the knowledge lecture group (1.8±0.5 yuan) (P<0.01). (3)The knowledge lecture group showed higher standard anticoagulation fulfillment rate (47.96%) than that of booklet group (32.60%) (χ2=7.33, P<0.01). There was no statistical difference in ischemic stroke rate, other artery embolism rate, major bleeding rate, minor bleeding rate and the death rate. Conclusions Detailed, correct anticoagulant education and guidance can improve NVAF patients with standard anticoagulation, and reduce the risk of ischemic stroke. Knowledge lecture consumes more time but can improve the standard anticoagulation fulfillment rate.

BACKGROUND:Primary culture of glomerular mesangial cells was less achievement ratio,short survival time,and less passage times.In particular,extraction of renal glomerulus remains difficult for culturing highly pure mesangial cell OBJECTIVE:To establish a more simple.high successful rate and good reproducibility method of human mesangial cells in primary cultureMETHODS:Kidneys jsolated from induction of labor with water bag voluntary were cut into pieces.and human mesangial cells were cultured with eugenic selection methods.Morphology was observed using inverted phase contrast microscope and transmission electron microscope,cell phenotype was detected using immunohistochemical method,and vimentin expression was observed using laser scanning confocal microscope.RESULTS AND CONCLUSION:The cultured mesangial cells were fusiform-shaped,irregular star-shaped,and slender.Organelle was rich in cytoplasm,cell process was clear,and microvillus was observed on the cell membrane.The cells expressed a-actin,myosin,vimentin,desmin but not expressed cytokeratin and Ⅷ factor.Laser scanning confocal microscope demonstrated that vimentin expression was positive and had the characteristics of fiber bundles.This suggested that the cultured intercapillary cells were coincidence with the characteristics of mesangial cell The renal corticaI tissue combined eugenic selection method was a simple and efficient method to culture human mesangial cells.

Objective To investigate the impact of relevant factors in mechanical ventilation on intraabdominal pressure in patients with ALI/ARDS by continuous monitoring of intra-abdominal pressure.Methods A total of 116 ALI/ARDS patients treated with mechanical ventilation in ICU were enrolled in this study.Intra-abdominal pressure (IAP) was recorded continuously.Meanwhile ventilator parameters, arterial blood gas analysis, hemodynamic variables, and as well as the levels of IL-4, IL-8 and TNF-α in blood and bronchial alveolar lavage fluid (BALF) were determined and recorded.The detection of risk factors for intra-abdomen hypertension (IAH) were carried out using multivariate stepwise logistic regression.ROC curve analysis used to estimate the diagnostic performance of these parameters for IAH.Results The oxygenation index (PaO2/FiO2) in patients with IAH after 2 hours' mechanical ventilation was significantly lower than that in patients with normal intra-abdomen pressure (IAP) (P ＜ 0.01);PEEP and RR in mechanical ventilation were higher in IAH group (P ＜ 0.01 or P =0.001);Mean artery pressure (MAP), ejection time percent (ET), stroke volume (SV), cardiac index (CI) were lower in IAH group than those in normal IAP group (P ＜ 0.01);the levels of IL-4, IL-8 and TNF-α in blood and bronchial alveolar lavage fluid were higher in IAH group than those in normal IAP group (P ＜ 0.01);IAH patients have a higher mortality on 28 d (Log rank test, P =0.023).Poor oxygenation index (PaO2/ FiO2) after 2 hours' ventilation, high PEEP setting, low MAP, ET, SV, CI and elevated IL-4 in the BALF were resulted in increasing risk of IAH for ARDS patients under mechanical ventilation support.Conclusions The monitoring of intra-abdominal pressure should be emphasized for ALI/ARDS patients when mechanical ventilation was employed.PaO2/FiO2, SV and IL-4 in BALF might be the independent risk factors of IAH.

Objective To search specific biomarkers of pathogenic bacteria in patients with sepsis so as to guide early using rationally antibiotic treatment.Methods Prospective survey of 147 patients with sepsis in ICU was carried out from Jan 2012 to Mar 2015.When patients blood culture was positive, clinical data including age, gender, vital signs, blood and, urine routine examination, DIC, blood biochemistry, c-reactive protein (CRP), procalcitonin (PCT), microbial detection, etc were recorded.Cultured blood samples were from central venous catheter and peripheral vessel.ELISA method was employed to detect soluble toll-like receptor 2 ( sTLR2 ) and interleukin-8 ( IL-8 ) , and the Acute Physiology and Chronic Health Evaluation Ⅱ( APACHEⅡ score ) was calculated.The chi-square test and analysis of variance were performed where necessary.Receiver operating characteristic ( ROC ) curves were used to calculate cut-points ( CP ) and area under the curve ( AUC) .Results According to the results of blood culture, patients were divided into three groups:GP group [ gram-positive bacteria ( G+) group];GN group [ gram-negative bacteria ( G-) group];FG group ( fungi group) .There were no significantly statistical differences in age, APACHEⅡ score, vital signs and markers of inflammation among three groups (P>0.05).Gram negative pathogenic bacterium was the most common microbe.Compared with GN group, the level of sTLR2 in the GP group was obviously higher ( P=0.000); but there was no significant difference in sTLR2 level between GP group and FG group (P=0.187). The amount of (1, 3) -beta glucan in the FG group was significantly higher than that in the GP group ( P=0.000).The sTLR2 level in FG group was obviously higher than that in the GN group (P=0.000).There were no significantly statistical differences in PCT, CRP and IL-8 among the three groups (P>0.05).For the diagnosis of gram negative bacteria infection, sTLR2 area under the curve was 0.768, and the sensitivity and specificity were 88.90%and 59.60%, respectively and the best cut-off point was 8.083 pg/mL.Namely, the diagnosis of gram negative bacteria infection was less likely, when level of sTLR2 was higher than 8.083 pg/mL.The markers of PCT, CRP, (1, 3) -beta glucan and IL-8 were less valuable for the diagnosis of Gram negative bacteria infection because the area under the curve was less than 0.5.Conclusions The combination of inflammatory indicators such as sTLR2 and (1, 3) -beta glucan etc, can imply the kind of pathogenic microorganisms partly.

Objective To explore the effect of the improved abdominal rotation card method in insulin injection. Methods A total of 100 hospitalized diabetes patients were randomly divided into control group (n=50) and observational group (n=50) according to the random number method. In the control group, insulin was injected to the subcutaneous tissue of abdomen with traditional method annular rotating method. Insulin was injected using improved abdominal rotation card method in the observational group. Compare accuracy and mastery rate of injection site rotation between the two groups. Compare fasting blood glucose (FBG), postprandial 2H blood glucose (PBG), HbA1c, the incidence of hypoglycemia and endermic induration between the two groups after three months. Results The nurses in the observation group had higher accuracy rate of the injection site rotation compared to the control group [98.6%(690/700) vs. 38.6%(270/700),χ2=584.66, P<0.01]. Mastery rate of the injection site rotation for the patients in the observation group were significantly higher than the control group [70.0% (35/50) vs. 20.0% (10/50), χ2=25.74, P < 0.01]. The incidence of endermic induration were significantly lower in observation group compared to the control group [2.0% (1/50) vs.16.0% (8/50), χ2=5.98, P < 0.01]. The incidence of hypoglycemia were significantly lower in observation group compared to the control group [4.0%(2/50) vs. 16.0%(8/50),χ2=4.00, P<0.01]. Conclusions The new abdominal rotation method in insulin injection can be a safe and effective therapy in patients with type 2 diabetes.

Objective To evaluate the efficacy and safety of rhTPO (recombinant human thromobopoietin) employed for the treatment of sepsis-associated thrombocytopenia. Method There were 47 patients with sepsis-associaiod thrombocytopcnia eligible for the prospective, randomized (random number) and controlled clinical study from January 2009 to November 2009 in ICU of the Tianjin First center Hospital. According to the principle of minimum distribution imbalance index, these patients were randomly divided into the rhTPO group (n = 21) and the IVIG (intravenous immunoglobulin) control group (n = 22). In the rhTPO group, rhTPO was given subcutaneously to patients in a dose of 300 U/kg/d for 2 ～ 8 d, and in the IVIG control group, IVIG was used instead of rhTPO in a dose of 400 mg/kg/d for 5 days. Laboratory tests included blood routine examination, hepatic function, kidney function, coagulation function. The amount of blood products used, bleeding events, the days of ICU and hospital stay, total therapy cost and 28-day mortality were compared between two groups. Results The maximal platelet count in the rhTPO group was significantly higer than that in the contral group (t = 2.21, P =0.032). The mean value of difference between minimal and maximal platelet counts in the rhTPO group was much higher than that in the control group (t =7.40, P ＜0. 001). The average platelet count was no statistical difference between two groups before treatment (t =0. 458, P ＞ 0.05), but the average platelet counts in the rhTPO group were significantly higer than those in the contral group on the second and third day after treatment(t = 2. 166 and t = 2. 132, P =0. 036 and P =0.041. There were no statistical differences in incidence of bleeding, length of ICU stay and mortality between two groups (χ2 =0.720, t =0.91 and χ2 =0.264, P ＞0.05) , but the amounts of plasma and platelet transfusion were significantly less in the rhTPO group than those in the control group (t = 2.038 and t =2.252, P=0.048 and P=0.030) and the medical cost was cut down significantly in rhTPO group (t = 16.93, P ＜ 0.001). There was no adverse reaction occurred during period of observation. Conclusions The rhTPO can significantly increase platelet count, and decrease the amount of blood transfused and the medical cost. The administration of rhTPO is safe and efficient for the treatment of sepsis-associated thrombocytopenia.
