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.

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.

Objective To observe the effect of Astragalus injection on the expressions of inflammatory cytokines in human primary macrophages stimulated by lipoteichoic acid (LTA) and lipopolysaccharide (LPS),and investigate its effects on inflammatory reactions of Gram-positive (G+) and Gram-negative (G-) bacteria sepsis and its mechanisms.Methods Percoll density gradient centrifugation was used to isolate the human peripheral blood mononuclear cells,then they were purified by immune Anti-Biotin Microbeads with magnetic character and under the induction of recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF),the cells were cultivated for 12 days in vitro,eventually the human monocyte-derived macrophage was formed.The cultured human macrophages were inoculated in 96-well plates (each group 3 wells) and 6-well plates (each group 3 wells).The cells were divided into control group (200 μL DMEM added in each well),LTA 1 mg/L group,LPS 0.1 mg/L group and low astragalus injection (0.1 mg/L) and high astragalus injection (0.2 mg/L) dose groups.After the incubator plates were put in an incubator for 24 hours,the protein content of IL-8 and IL-10 in supernatant were detected by enzymelinked immunosorbent assay (ELISA),and the mRNA expression levels of IL-8 and IL-10 were detected by real time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-qPCR).Results LTA and LPS all can obviously up-regulate the expression levels of pro-inflammatory factor IL-8 and anti-inflammatory factor IL-10 of macrophage.The expressions of IL-8 and IL-10 protein and mRNA in LTA group and LPS group were significantly higher than those in control group after cuhure for 8 hours and 24 hours,the degrees of increment were more significantly at 24 hours [LTA stimute group:IL-8 protein (ng/L,× 103):41.57± 1.90 vs.1.58 ±0.24,IL-8 mRNA (A value):21.49±8.05 vs.1.00±0.16;IL-10 protein (ng/L):5.90±3.02 vs.2.91 ± 1.54,IL-10 mRNA (A value):1.35±0.34 vs.0.95±0.14;LPS stimute group:IL-8 protein (ng/L,× 103):345.00±22.80 vs.5.60±0.31,IL-8 mRNA (A value):29.84 ± 8.93 vs.1.00 ± 0.16,IL-10 protein (ng/L):122.37 ± 39.26 vs.44.79 ± 3.67,IL-10 mRNA (A value):7.38 ± 1.58 vs.1.35 ± 0.34,all P ＜ 0.05].The Astragalus injection could regulate LTA and LPS to stimulate the macrophage to decrease the expression levels of pro-inflammatory factor IL-8 protein and mRNA and increase the expression levels of anti-inflammatory factor IL-10 protein and mRNA in the macrophage;the changes of regulatory effect in the 24 hour-culture of Astragalus injection high dose group was the most significant [LTA stimute group:IL-8 protein (ng/L,×103):22.63±1.91 vs.41.57±1.90,IL-8 mRNA (A value):12.10±1.93 vs.21.49±8.05,IL-10 protein (ng/L):14.03±2.22 vs.5.90±3.02,IL-10 mRNA (A value):10.37±6.08 vs.1.35±0.34;LPS stimute group:IL-8 protein (ng/L,× 103):167.75 ± 19.90 vs.345.01 ±22.80,IL-8 mRNA (A value):15.61 ± 3.63 vs.29.84±8.93;IL-10 protein (ng/L):243.22±14.41 vs.122.37±39.26,IL-10 mRNA (A value):16.14±4.10 vs.7.38± 1.58,all P ＜ 0.05].Conclusions In the process of inflammatory response,the pro-inflammatory and anti-inflammatory factors co-exist simultaneously.Astragalus injection can inhibit the expression levels of pro-inflammatory factor gene and protein in the inflammatory response of G+ and G-bacteria sepsis and in the mean time,it can promote the expression levels of anti-inflammatory factor gene and protein,thus the immune mechanism of sepsis is affected,achieving the balance between pro-inflammation and anti-inflammation.

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.

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.
