RESUMO
Objective To investigate the effect of high expression of protein tyrosine phosphatase SHP-1 on the tumor cell invasiveness and chemosensitivity of esophageal squamous cell carcinoma.Methods EC9706 ceils of esophageal squamous cell carcinoma were divided into three groups:the blank group was not given any treatment;the experimental group used SHP-1 mimic instantaneous vector to transfect cells for 24 h,and used 10 μmol/L cisplatin to treat EC9706 cells for 12 h;the control group selected 10 μmol/L cisplatin to treat EC9706 cells for 12 h.Cell proliferation was detected by using methyl thiazolyl tetrazolium (MTT) assay,and cell invasion was detected by using Transwell chamber.The expression of SHP-1 mRNA was detected by using fluorescence quantitative polymerase chain reaction.The expression level of SHP-1 protein was detected by using Western blot.Results The expression of SHP-1 mRNA in the experimental group (3.42t0.14) was higher than that in the control group and the blank group (1.09±0.13,0.42±0.24,F =9.143,P ＜ 0.05).Compared with the control group and the blank group,the cell growth inhibition rate and the apoptosis index in the experimental group were increased (both P ＜ 0.05),and the differences between any two groups were also statistically significant (all P ＜ 0.05).The cell invasion rate in the experimental group,the control group and the blank group was (6.5±1.3) ％,(18.5±2.5) ％ and (45.2±7.2) ％,respectively,and the difference was statistically significant (F =11.853,P ＜ 0.05).Conclusion High expression of SHP-1 can inhibit the invasion of esophageal squamous cell carcinoma,improve chemosensitivity,promote apoptosis and inhibit cell proliferation,which could lay a theoretical foundation for improving the efficacy of chemotherapy for esophageal squamous cell carcinoma.
RESUMO
Objective To study the effect of tranexamic acid of reducing the bleeding and transfusion on total hip arthroplasty and the recovery of joint function.Methods The clinical data of 62 patients who underwent total hip arthroplasty from February 2013 to February 2015 were randomly divided into the control group(31 cases)and the observation group(31 cases).Patients treated with tranexamic acid for hemostasis were the observation group and patients without tranexamic acid for the control group.The Hct,Hb and Harris scores were compared before and after operation.The total blood loss,intraoperative blood loss,postoperative drainage,occult blood loss and blood transfusion were compared between the two groups.Results The preoperative Hct,Hb and Harris scores in observation group were 0.43±0.06,(131.13±18.52)g/L and(23.45±10.24)points,respectively,0.42±0.05,(130.42±14.36)g/L and(24.36±9.34)points,respectively in control group.Postoperative 1st,3th d Hct in observation group were 0.35±0.05,0.28±0.05,in control group were 0.30±0.06,0.25±0.03,postoperative Hb in observation group were(111.58±20.32)g/L,(121.26±18.28)g/L in control group.Postoperative 2nd,6th,12th weeks Harris scores in observation group were(54.88±6.14)points,(67.79±12.05)points,(83.55±12.12)points,in control group were(50.21±5.01)points,(58.17±13.24)points,(74.38±12.67)points,compared with before treatment were improved,and three indexes in the observation group were significantly higher than those in control group(F between grouP=3.213,P=0.023,F across grouP=3.213,P=0.036,F inner grouP=3.327,P=0.032;F between grouP=3.277,P=0.002,F across grouP=2.865,P=0.006,F inner grouP=3.564,P=0.001;F between grouP=3.327,P=0.016,F across grouP=32.912,P=0.005,F inner grouP=3.614,P=0.001).The patients total blood loss,the amount of hemorrhage,postoperative drainage volume,the hidden blood loss and blood transfusion in the observation group were(1 820.9±367.6)ml,(685.5±363.62)ml,(561.3±366.1)ml,(530.8±410.7)ml and(210.1±25.9)ml,respectively,less than the control group((2 229±564.6)ml,(1 010.3±415.11)ml,(725.9±257.8)ml,(798.4±279.5)ml,(701.2±51.2)ml,with significant differences between the two groups(t=3.373,3.281,2.047,2.999,47.655,P＜0.05).Conclusion Intraoperative hemostasis of tranexamic acid in total hip arthroplasty can effectively reduce the amount of blood loss and blood transfusion,and to promote patients recovery of joint function,clinical promotion,with great value of clinical promotion.
RESUMO
Objective To investigate the relation between VEGF and prognosis of lung carcinoma.Methods ESISA was used to investigate the level of VEGF in lung carcinoma group,pulmonary disease group and normal group,and evaluate the diagnostic efficiency of lung carcinoma transfer or dead.Results The levels of VEGF in lung carcinoma group and pulmonary disease group were significantly higher than those in normal cases(P0.05).The level of VEGF in pulmonary disease group had a degression after treatment.The negative rate of lung carcinoma was 76%.The transfer rate in the increases group of lung carcinoma was 65% in the six month.The dead rate was 10%(P
RESUMO
Objective To investigate the effect of co transfusion of bone marrow mesenchymal stem cells(BMMSC) on hematopoietic recovery in mice after allogeneic bone marrow transplantation(allo-BMT).Methods Both BMMSC obtained after three to four weeks of culture and bone marrow cells of donor mice C57BL/6(H-2~b) were transplanted into the recipient mice BalB/c(H-2~d) that were lethally irradiated.Peripheral blood cells were counted on day 1,7,and 14 post-transplantation.CFU-S in recipient bone marrows were measured on day 7 and 14.Results The numbers of peripheral WBC,RBC,platelets and the number of CFU-S in recipient bone marrows on day 7 and 14 were all significantly higher in the co-infusion group than those in control group(P
