Objective To investigate the mechanism of interlekin-6 (IL-6) in wound healing of human biliary epithelial cells ( BECs ).Methods BECs were cultured in IL-6 at different concentrations:0 ng/L(0 ng/L group),10 ng/L (10 ng/L group),50 ng/L (50 ng/L group),100 ng/L (100 ng/L group),1000 ng/L ( 1000 ng/L group).The effects of IL-6 on the phosphorylation of signal transducer and activator of transcription 3( STAT3 ) and the expression of trefoil family factors 3 (TFF3) were detected.BECs were divided into untreated group,STAT3-RNAi group (BECs transfected with STAT3 RNAi adenovirus) and Control-RNAi group (BECs transfected with vacant RNAi adenovirus).The effects of IL-6 on the expression of TFF3 were detected after RNAi of STAT3.In vitro wound models were constructed for the untreated group,STAT3-RNAi group and Control-RNAi group,and the effects of IL-6 and TFF3 on BECs of the 3 groups were detected.All data were analyzed by using the Student's t test,analysis of variance or Sidak test.Results The expressions of phosphorylated STAT3 in the 50 ng/L group,100 ng/L group and 1000 ng/L group were 0.240 ± 0.052,0.714 ± 0.124,0.327 ± 0.069,respectively,which were significantly higher than 0.033 ± 0.011 of the 0 ng/L group (q =5.246,17.260,7.451,P ＜ 0.05 ).The contents of mRNA and protein of TFF3 increased as the increase of IL-6 concentration (q =12.045,9.889,P ＜ 0.05).After RNAi of STAT3 of the BECs,the expression of TFF3 decreased when the concentration of IL-6 was 1000 ng/L.The expression of TFF3 of the STAT3-RNAi group was 0.037 ± 0.005,which was significantly lower than 0.267 ± 0.038 of the Control-RNAi group and 0.301 ± 0.042 in the untreated group ( q =12.135,13.929,P ＜ 0.05 ).In the in vitro wound model,the speed of BECs migration in the STAT3-RNAi group was (9.1 ± 1.5 ) μm/h,which was slower than (25.1 ± 3.8 ) μm/h of the Control-RNAi group after 12 hours of interference with IL-6 (q =7.737,P ＜ 0.05 ).The speed of BECs migration of STAT3-RNAi group was (39.2 ± 4.7) μm/h after adding 1 g/L of recombinant TFF,which was significantly faster than that of the Control-RNAi group (q =14.507,P ＜0.05).Conclusion IL-6 promotes cell migration and wound healing by activating STAT3 and up-regulating TFF3 expression.

Objective To compare the clinical results of endovenous laser treatment(EVLT),radiofrequency endovenous occlusion(RFO)and conventional stripping combined with transilluminated powered phlebectomy(TIPP)for lower extremity varicose vein.Methods From Jun 2004 to Jan 2007,200 cases(232 limbs)were treated by EVLT with TIPP,80 cases(88 limbs)by RFO with TIPP,and 180 cases(202 limbs)by conventional stripping with TIPP.Operation time,number of the incision made,intraoperative bleeding,postoperative hospital stay,complications,and one-year recurrence rate were compared with each other. Results Operation time was longer(41±8)min in RFO group than that in other two groups.Postoperative hospital stay was shorter in EVLT group(1.2±0.4 d)and RFO group (2.1±0.8 d)than that in stripping and TIPP group(P＜0.05).Patients in stripping group also suffered from more intra-operative bleeding more often incidental nervus saphenus injury and more incision numbers when compared with other two groups(P＜0.05).There was no significant difierence in one-year recurrence rate among patients in the three groups. Conclusions The clinical efficacy is almost the same among the three groups in terms of eradication of the varicose veins.EVLT and RFO are safe and minimal invasive for the treatment of lower extremity varicose vein.

Objective To evaluate the clinic effect of local resection plus axialla lympha nodes dissection on treating early stage breast cancer. Methods 112 cases of early stage breast cancer in PLA309 Hospital were divided into 2 groups: local resection plus axially dissection group (46 cases) and Halsted's operation group (66 cases). The survival rate,local recurrence rate,metastasis rate, and casmetic effect of breast were followed up for long time. Results In treatment group, the 3,5,8 years survival rates were 97.8%, 80.5%, 76.1% respectively. In control group 3,5,8 years survival rates were 97.0%, 87.9% and 71.2% respectively. The rate of local recurrence was 4.3% in treatment group and 4.6% in control group.The metastasis rate in treatment group was 19.6%, in control group was 16.7%. 93.2% of patients in treatment group kept good breast figure. Conclusions Local resection plus axially dissection, with the same effect as Halsted procedure, is an ideal method in treating early stage breast cancer.

Objective To investigate the pathological and clinical effects of preoperative intra arterial infusion chemotherapy for patients with advanced breast cancer.Methods The clinical data of 52 patients with advanced breast cancer were analyzed retrospectively.Twenty two patients were treated with preoperative intra arterial infusion chemotherapy (treatment group),and 30 were treated without preoperative intra arterial infusion chemotherapy (control group).Results In the treatment group,the tumour size reduced and symptoms relieved after intra arterial infusion chemotherapy in 86.4% of the patients.Pathological examination of the specimens showed that raryopyknosis,raryorrhexis,cytoplasm coagulation and necrosis in cancer cells around the vascular vessels were found in all patients.Interstitial edema,inflammatory cells infiltration ,fibroelastosis around the cancer cells,proliferous intima thrombus and inflammation of vessels were also found.But in the control group,the histological chang of cancer cell was not found yet.All patients were followed up for 2 to 7 years.Local recurrence rate in the treatment group was 13.6%, while that of the control group was 33.3% (P

Objective To observe the effect of the 8-word bandage on the walking ability of stroke patients with knee hyperextension. Methods Fifty patients with stroke combined with knee hyperextension were randomly divided into the observation group and the control group with 25 cases in each group. The control group was treated with conventional methods, including Bobath technology, Brunnstrom therapy and motor relearning primarily rehabilitation training. In addition to the conventional methods, patients in the observation group used 8-word bandage to fix knee joint in walking training. Before and after 8 weeks of treatment, Holden walking function classification, 10-meter maximum walking speed and improved Barthel index were adopted to evaluate the walking ability, maximum walking speed and the life ability of the patients. Results There were no significant differences in the scores before treatment between the two groups. The Holden walking function classification, the 10-meter maximum walking speed and the Barthel index scores were significantly improved after 8-week treatment in both two groups (P<0.05), and patient conditions were more significantly improved in the observation group than those of the control group (P<0.05). Conclusion Using 8-word bandage to fix knee joint can significantly improve knee hyperextension in patients with stroke, so as to improve the walking ability and activities of daily living.
