Objective To investigate the potential mechanism of intestinal trefoil factor(ITF)against methotrexate (MTX)- induced injury in intestinal mucosa. Methods Cultured IEC-6 cells were divided into groups as follows: blank group, MTX treated group, ITF treated group and experimental group treated with gradient concentrations of ITF plus MTX. Expression of E-cadherin mRNA was determined by Real-Time polymerase chain reaciton (RT- PCR). The activity of matrix metalloproteinase(MMP)-2 and MMP-9 was measured by gelatin zymogramphy. Caspases-3 activity was measured by colorimetric assay. Cell proliferation was assessed by cell counting kit-8 (CCK-8)assay. Migration of IEC-6 in vitro was observed using modified Boyden chamber assay. Results The expression of E-cadherin mRNA in experimental group (treated with 0.1 mg/ml or 1 mg/ml of ITF) was significantly down-regulated (0. 538±0. 109 or 0. 528±0. 132, respectively) in comparison with MTX treated group (0. 763±0. 139) with significant difference (P=0. 021 or P=0. 025, respectively). There was no significant difference in activity of MMP-2 and MMP-9 among groups (P>0. 05). When compared with MTX treated group (0. 090 ±0. 011 ), the activity of Caspase3 in experimental group (treated with 0. 1 mg/ml or 1 mg/ml of ITF) was significantly decreased (0. 077±0. 009, P=0. 032 or 0. 044±0. 009,P=0. 005, respectively). There was no statistical difference in cell proliferation between experimental group (treated with 1 μg/ml, 0.01 mg/ml, 0. 1 mg/ml or 1.0 mg/ml of ITF) and MTX treated group (P=0. 132,0. 150,0. 114 or 0. 367, respectivley). More migratory cells attached to the bottom surface of the membrane in experiment group (treated with 0. 1 mg/ml or 1 mg/ml of ITF) in comparison with MTX treated group (P <0. 001 ). Moreover, more migratory cells were found in experimental group treated with 1.0 mg/ml of ITF than those in group treated with 0. 1 mg/ml of ITF (P<0. 001). Conclusions Without cell proliferation, the protective effect of ITF is related to its functions of promoting cell migration and inhibiting cell apoptosis, which may down-regulate expression of E-cadherin mRNA.

Objective To investigate the effect of low-dose of cefuroxime combined with dexamethasone on postoperative urinary tract infection and quality of life in cervical cancer.Methods 90 cases of cervical cancer patients from July 2015 to July 2016 in the first affiliated hospital of wenzhou medical university were selected and divided into two groups,44 patients in control group received cefuroxime sodium 1.5 g and metronidazole 0.5 g biw in five days,furacilin 250 mL bladder irrigation biw after five days,and fourteenth days out of indwelling catheter.46 cases in the experiment group received more with cefuroxime 125 mg and dexamethasone 0.75 mg oral,and two groups were treated for 14 days.Results After treatment,the incidence rate of urinary tract infection rate,the first urination time>three hours and residual urine ≥100 mL in the experiment group were lower than the control group (P<0.05);the total effective rate of the experiment group was significantly higher than the control group (P <0.05);the scores of physical function,physical life, mental health and social adaptation in the experiment group were significantly higher than the control group ( P <0.05 ) . Conclusion Low dose cefuroxime combined with dexamethasone have better prevention effect on urinary tract infection after cervical cancer operation , can significantly improve the quality of life of patients and treatment efficiency.
