BACKGROUND:Fibrin glue can function to close the wound tissue, reduce leakage, stop bleeding, promote wound healing and prevent adhesion.
OBJECTIVE:To systematicaly review the application of fibrin glue in thyroid surgery.
METHODS:We searched China Journal Net database, Wanfang database, VIP database, Chinese Biomedical Database Online to retrieve clinical randomized controled trials related to fibrin glue applied in thyroid surgery from January 2000 to April 2013. Included studies were analyzed using Rev Man 5.2 statistical software for Meta-analysis.
RESULTS AND CONCLUSION:A total of six studies including 797 cases were enroled in result analysis. Meta-analysis showed that the drainage volume at postoperative day 1 and total postoperative drainage volume were higher in the fibrin glue group than the control group (without fibrin glue) [odds ratio=-27.36, 95% confidence interval (-33.86,-20.87),P < 0.00001; weighted mean difference=-38.73, 95% confidence interval (-44.78,-32.67),P < 0.000 01]. The suture removal time was shorter in the fibrin glue group than the control group [odds ratio=-2.00, 95% confidence interval (-2.17,-1.83),P < 0.000 01]. No significant difference was found in the postoperative 3-day fever incidence [odds ratio=1.53, 95% confidence interval (0.59,3.96),P=0.38], wound infection [odds ratio=0.86, 95% confidence interval (0.12, 6.15),P=0.88], and postoperative hematoma [odds ratio=0.86, 95% confidence interval (0.21, 3.48),P=0.83] between the two groups. These findings indicate that fibrin glue used in thyroid surgery can significantly reduce drainage by non-increasing postoperative complications.

BACKGROUND:Currently, in pterygium excision combined with limbal epithelial transplantation, there were stil some controversies about whether the medical fibrin glue could instead of stitch fixing autologous conjunctival graft. OBJECTIVE:To compare the therapeutic effect of medical fibrin glue and stitch in pterygium excision combined with limbal epithelial transplantation using Meta analysis. METHODS: The randomized controled trials about the therapeutic effect of medical fibrin glue versus stitch in pterygium excision combined with limbal epithelial transplantation were reviewed from PubMed database, CNKI ful-text database, Chinese Biomedical Literature Database, VIP database and Wanfang database from database creation to June 2015. The operative time, complications and recurrence rate of these two groups were analyzed using Meta. RESULTS AND CONCLUSION:A total of 14 randomized controled trials, and 879 patients were enroled. Meta-analysis results showed that the operative time, incidence of postoperative complications, the relapse rate after six months and one-year in the fibrin glue group were lower than those in the suture group [MD=-15.58, 95%CI (-18.96,-12.21),P < 0.000 01]; [OR=0.39, 95%CI(0.19, 0.68),P=0.02]; [OR=0.28, 95%CI(0.12, 0.65),P=0.003]; [OR=0.23, 95%CI(0.07, 0.76),P=0.02]. These results demonstrate that the application of fibrin glue in pterygium excision combined with limbal stem cel transplantation can promote graft attachment, shorten the operation time, reduce postoperative complications and reduce the postoperative recurrence of pterygium.

AIM:To investigate the role of high glucose in primary hepatocytes of mice fed with a high fat di-et.METHODS:Male C57BL/6J mice were fed a high fat (45%of calories) diet ad libitum for 6 weeks to induce hepatic steatosis.Primary hepatocytes were isolated from the mouse liver by the 2 step collagenase perfusion method .The cells were incubated in low glucose ( 5 mmol/L ) , low glucose plus mannitol ( 30 mmol/L ) , or high glucose ( 35 mmol/L ) DMEM medium for 12 h.The cell viability , apoptosis , mitochondrial membrane potential , and caspase enzymatic activities were measured.Furthermore, proteins related to the stress-sensitive signaling pathway of regulating high glucose-induced apoptosis in primary hepatocytes were determined by Western blotting .RESULTS:Incubation with 35 mmol/L glucose re-sulted in a significant decrease in cell viability and an increase in apoptosis , whereas mannitol had no significant effect on the cell viability or apoptosis .A progressive depolarization of the mitochondria , an increase in cytosol cytochrome C and a dramatic decrease in mitochondrial cytochrome C in high-glucose stressed hepatocytes were observed .The enzymatic activi-ties of caspase-9 and caspase-3, but not caspase-8, were significantly increased in high glucose-stressed hepatocytes ( P<0.05).High glucose treatment suppressed the expression of Bcl-2 and Bcl-xL, while it increased the expression of the pro-apoptotic factor Bax .CONCLUSION:High glucose stress reduces mitochondrial membrane potential , initiates mitochon-dria-mediated apoptotic pathways and promotes apoptosis of hepatocytes with steatosis .This may be an important pathologi-cal mechanism of hyperglycemia-induced progression of nonalcoholic fatty liver disease .

Objective To discuss the role of DNA-dependent protein kinase catalytic subunit (DNA-DPKCS) in human lung adenocarcinoma cell line (A549) by using small interfering RNA (siRNA) to specifically knockdown DNA-DPKCS expression and its effects on cell proliferation, cell cycle and radio-sensitivity. Methods The DNA-DPKCS-siRNA expression vector was constructed and transfected into A549 cell line. The transformed clones were randomly selected and isolated. The cell cycle distribution and apop-tesis were analyzed by flowcytometry analysis. Cell survival was detected by using clonogenic formation as-say. Results With specific inhibition of DNA-DPKCS expression, stable transfected cell line 549pRNA-DNA-DPKCS was constructed by RNA interference technique. The 549pRNA-C and 549pSUPER cell lines were the control cell lines tansfected with control and blank plasmids, respectively. Compared with A549 cells, the expression levels of DNA-DPKCS mRNA (0.110: 1. 000), protein (0. 870: 2.967) and activity of DNA-DPKCS (0.004: 0.266) in 549pRNA-DNA-DPKCS cells were significantly lower (F = 80.55 ,P < 0.01;F=63.96, P<0.01;F=51.62,P<0.01, respectively). The analysis of SF_2(0.25:0.76), D_0 (1.42:1.62) and D_q (0.06: 1. 00) showed significant difference between 549pRNA-DNA-DPKCS and A549 cells (F = 996.86, P < 0.01 ; F = 17.41, P < 0.05 ; F = 68.92, P < 0.01). The number of 549pRNA-DNA-DPKCS cells in S (24.5%: 35.5%) and G_2 (10.7%: 11.0%) phases was significantly decreased (F = 4.83, P<0.05 and F=32.04, P <0.01, respectively). Conclusions In A549 cells, inhibit of DNA-DPKCS gene expression can enhance the radiosensitivity and affect cell cycle distribution.

Objective To analyze the correlation among serum total IgE(TIgE),blood eosinophil(EOS) counts,the degree of sensitization for skin prick test(SPT),and fractional exhaled nitric oxide(FeNO)in chil-dren with asthma and allergic rhinitis.

Purpose To evaluate the correlation between carotid elasticity and age using electrocardiogram (ECG)-gated multi-detector CT angiography (MDCTA).Materials and Methods ECG-gated multiple phases MDCTA was performed on 34 vascular health subjects. Cross-section of the internal carotid artery (ICA), carotid bulb (CB) and common carotid artery (CCA) were measured at different phases. Carotid elasticity at ICA (EICA), CB (ECB) and CCA (ECCA) was calculated based on the carotid cross-sectional area changes and pulse pressure (PP).Results The EICA, ECB and ECCA showed significantly negative linear correlation with age (r=-0.73,-0.74 and-0.64,P<0.01). Conclusion The ECG-gated MDCTA is a novel method to evaluate carotid elasticity quantitatively and reliably. Carotid elasticity decreases with aging in vascular health population.

ABSTRACT:Objective To investigate the effects of total flavones of oldenlandia diffusa (FOD)on epithelial-mesenchymal transition in hepatocellular cancer cell line MHCC97-H.Methods TGF-β1 induced EMT in routinely cultured liver cancer cell line MHCC97-H;then MHCC97-H cell was divided into 5 groups:normal control group, TGF-β1 group,TGF-β1 + FOD group,TGF-β1 + 5-FU group,and TGF-β1 + FOD + 5-FU group.After 48 h of treatment,the invasion ability of MHCC97-H cell was detected by Transwell;the proteins of E-cadherin and vimentin were determined by Western blot.Results Compared with the normal form of MHCC97-H cell line,the cell had obvious long fusiform after TGF-β1 induction,and the invasion ability enhanced (P = 0.02 ).But after treatment,the invasion ability of MHCC97-H cell decreased in FOD group and 5-FU group compared with that in TGF-β1 group (P = 0.03,P = 0.02 ),and decreased more significantly in FOD + 5-FU group (P = 0.01 ).The expression of E-cadherin at the protein level decreased significantly (P = 0.01 )in TGF-β1 group,which was abolished in FOD group (P =0.03 )and 5-FU group (P = 0.02 ).The expression of vimentin at the protein level increased significantly (P =0.01)in TGF-β1 group,which was abolished in FOD group (P =0.04)and 5-FU group (P =0.03)and more obviously in FOD+5-FU group (P =0.01).Conclusion FOD can reverse the invasion of MHCC97-H cells in EMT induced by TGF-β1 through decreasing the expression of E-cadherin protein and inhibiting the epithelial-mesenchymal transition of MHCC97-H cell.

The perioperative indexes and postoperative abdominal infection were compared between the two groups.Results:In intracorporeal anastamosis group, the intraoperative bleeding was (45.2±4.2) mL, the operative time was (161.3±22.4) min, the number of lymph node dissection was (30.8±9.6), the postoperative exhaust time was (3.3±1.2) d, and the postoperative hospital stay was (7.6±0.5) d. In extracorporeal anastamosis group was (42.1±5.0) mL, (167.3±26.7) min, (32.9±8.6), (3.4±1.0) d and (7.5±0.6) d, respectively, there were no significant difference between the two groups (t value were 0.417, 0.207, 0.829, 0.338 and 0.293, respectively; P value were 0.699, 0.845, 0.231, 0.734 and 0.802, respectively). In intracorporeal anastamosis group, the incidence of abdominal infection (with anastomotic fistula)was 13.9%(11/79), the incidence of abdominal infection (without anastomotic fistula)was 10.1%(8/79), and in extracorporeal anastamosis group was 1.5%(2/131)and 0.8%(1/131), the differences were statistically significant (χ 2=12.805, 10.238; P=0.003, 0.008). In intracorporeal anastamosis group, the incidence of respiratory system infection was 1.3%(1/79), the incidence of urinary system infection was 2.5%(2/79), the incidence of surgical incision infection was 1.3%(1/79). In extracorporeal anastamosis group was 3.1%(4/131), 0.8%(1/131) and 3.1%(4/131), respectively.There were no significant difference between the two groups (χ 2 value were 0.662, 0.420 and 0.662, respectively; P value were 0.364, 0.587 and 0.364, respectively). Conclusion:Laparoscopic right hemicolectomy with intracorporeal anastamosis and extracorporeal anastamosis have the same surgical effect, but intracorporeal anastamosis may increase the risk of postoperative abdominal infection.
