Objective:To investigate the effect of nurse-led multiple disciplinary team-based intervention in the prevention of venous thromboembolism in paitents undergoing general surgery.Methods:A total of 118 patients who underwent general surgery in the Tianjin First Central Hospital from May 2017 to October 2018 were divided into study group and control group by random digits table method, with 59 cases in each group. The control group received routine thrombosis prevention nursing, the study group carried out nurse-led multiple disciplinary team-based intervention. The condition of lower limbs deep venous hemodynamic was detected by color Doppler ultrasonography at 3 days after surgery, the levels of D-dimer, thrombelastograph coagulation analyzer (TEG) coagulation parameters were also measured at after 24 hours of admission and postoperative day 3, respectively.Results:The vein blood stasis rate was 94.9% (3/59) in the study group, 79.7% (12/59) in the control group, the venous blood flow of the lower 1imbs in the study group was better than that in the control group ( Z value was 2.477, P<0.05). At 3 days after surgery, the levels of D-dimer were (5.26±1.42) mg/L in the study group, (6.36±1.58) mg/L in the control group, D-dimer was decreased in study group compared to the control group, the difference was statistically significant ( t value was 3.991, P<0.05). Coagulation reaction time(R) value and solidification angle(Angel), maximum thrombus intensity(MA), composite coagulation index(CI) levels were (5.30±0.91) min, (69.64±21.93) deg, (65.40±13.76) mm and (1.23±0.20) in the study group, those index were (4.41±0.75) min, (76.64±16.02) deg, (70.98±13.39) mm, (2.09±0.36) in the control group, R value were increased and Angel, MA, CI levels were decreased in the study group compared to the control group ( t value was 2.001-15.997, P<0.05). Conclusions:Nurse-led multiple disciplinary team-based intervention improves the lower limbs deep venous hemodynamic and coagulation function, as well as reduce the incidence of venous thromboembolism.

Objective To study the expression profile of microRNAs in the lung adenocarcinoma tissue and its expression in CD133+ lung cancer cells .Methods The specimens of adenocarcinoma tissue and pericarcinomatous tissue were collected for con-ducting the microRNA expression chip analysis .The flow cytometry(FCM ) was adopted to sort and culture CD133+ A549 cells in serum-free medium for 2 weeks .The positive rate of CD133+CD44+ in those cells was assayed .The expression of miRNA-892b and miRNA-4686 in CD133+ A549 cells were detected by real-time qPCR .Results Compared with the pericarcinomatous tissue ,27 miRNAs expressions in the lung adenocarcinoma tissue were up-regulated(P<0 .05) and 6 miRNAs expressions were down-regula-ted(P<0 .05) .The positive rate of cancer stem like cells CD 133+CD44+ was 75 .0% .The expression of miRNA-892b and miRNA-4686 in CD133+ A549 cells was higher than A549 cells(P<0 .01) .Conclusion Abnormal expression profile of miRNAs in lung ad-enocarcinoma tissue ,and miRNA-892b and miRNA-4686 may play a certain role to maintain the biological characteristics of CD133+ lung cancer cells .
