Objective To investigate the risk factors of wound complications following the abdominal aorta balloon occlusion in order to provide the basis for the preoperative management and reduce postoperative complications.Methods Two hundred and sixty-one patients with the sacral tumor aged over 18 were selected as subjects who hospitalized at Peking University People's Hospital from January 2006 to December 2012.All subjects were underwent sacral tumor posterior resection operation after occlusion of the distal abdominal aorta.Patients were divided into two groups according to the existence of postoperative wound disorder.The general information of the patients was collected including intra-operative data and post-operative data.SPSS19.0 software was applied for statistic analysis Results Among 261 cases,89 cases were with incision complications,and the incidence of complications was 34.1％ (89/261).There was no significant difference regarding of age,weight,preoperative complications (P ＜ 0.05).Compared with that of no complications group,operation time of wound complications group was longer ((218.27 ± 72.08) min vs.(197.40 ± 53.92) min,P =0.046),and intra-operative bleeding was more ((2368.0 ± 1984.7) ml vs.(1701.6 ±958.8) ml,P =0.000),as well as a longer balloon occlusion time ((78.0 ± 23.8) rain vs.(65.2 ± 17.8) min,P =0.005).Moreover long hospitalized periods was in wound complications group ((47.6 ± 26.3) d,vs.(26.7 ± 9.0) d,P ＜ 0.05).Single factor analysis showed that the factors including operation time,intra-operative bleeding volume,time and times of balloon occlusion balloon occlusion were related to postoperative wound complications.Non conditional logistic regression analysis shows that factors of the balloon occlusion time(OR 1.028,95％ CI 1.012-1.045,P =0.001) and block number(OR 6.266,95％ CI 1.186-33.119,P =0.031) were related to the wound healing following balloon occlusion the abdominal aorta.Conclusion The risk factors of wound complications following the abdominal aorta balloon occlusion included occurrence balloon occlusion time and blocking times.That single balloon occlusion with 60 min reduced wound complication rate.

[Objective] Gestational function of endometriosis (EMT) model induced by endometrium autotransplantationwas observed to verify its feasibility for the research of pathological status of human infertility induced by EMT. [Methods]EMT rat models were established by endometrium autotransplantation according to the literature. The endocrine and immunefunction and the gestational function in model rats (Group B) were observed and were compared with the normal rats(Group A). [Results] The pathologic changes such as the increase of serum tumor necrosis factor occur in the model rats(P

Object To investigate clinical features,surgical strategy and prognostic factors of bone metastasis from thyroid cancer.Methods A total of 46 patients with bone metastasis from thyroid cancer,who had undergone surgical treatment from January 1999 to July 2011 and had complete follow-up data,were enrolled in this retrospective study.There were 20 males and 26 females,aged from 40 to 87 years (average,56.87 years).Forty two (91.3％) cases of metastatic lesion located in axial skeleton,while 4 (8.7％) in limbs.The tumor histology type was well-differentiated in 35 patients and poorly differentiated in 11 cases.Nineteen patients (41.3％) had an isolated metastatic bone lesion,while other 27 patients (58.7％) had multiple lesions.Kaplan-Meier survival curve and Cox regression model were performed to identify prognostic factors among 19 factors including gender,age,tumor subtype,number of bone metastasis,site of bone metastasis,visceral metastasis,skeletal-related events,timing of metastasis,whether metastatic lesion was detected when thyroid cancer was diagnosed,whether thyroid surgery was performed,whether 131Ⅰ therapy was performed,whether chemotherapy or radiotherapy were performed,preoperative general condition (good or poor),surgical type (excisional surgery or palliative surgery),characteristics of metastatic lesion (osteolytic or mixed),intraoperative blood loss,whether measures were applied to prevent intraoperative bleeding,perioperative complications and long-term complications.Results Excisional surgery was performed in 36 patients (78.3％),while palliative surgery in other 10 patients (21.7％).The average amount of blood loss was 2603.26ml.The postoperative 5-year survival rate and 10-year survival rate were 37.3％ and 12.4％,respectively.Univariate analysis showed the significant prognostic factors include tumor subtype,number of bone metastasis,whether 131Ⅰ therapy was performed,and preoperative general condition (good or poor).Multivariate analysis showed the independent prognostic factors were number of bone metastasis (solitary or multiple) and whether 131Ⅰ therapy was performed.Conclusion For patients with bone metastasis from thyroid cancer,the prognostic factors are useful for determining indications for operation and improving treatment outcome.

Objective To investigate the effects of simultaneous hepatic artery and portal revaseularization on the expression of TNF-α during bile duet ischemia-reperfusion injury in rats liver transplantation.Methods Male Spragne-Dawley rats were used to establish an autologous orthotopic liver transphmtation model.Model rats were random divided two groups,simultaneous revascularization group(sroup P)and portal vein revascularization group(group N).The animals were separately killed at the 2nd hour,6th hour and 24th hour after reperfusion.Plasma samples were collected for ALT,AST,GGT,AKP,TBiL and DBiL test.Bile duct tissues were collected to detect the histolosical changes,MPO activit,and the expression of TNF-α mRNA.Results The serum levels of GGT in group P was significantly lower than that in group N at the 6th hour and 24th hour after reperfusion(P＜0.05).And the serum levels of AKP,TBiL and DBiL and the morphological scores of bile duct in group P were significantly lower than that in group N at the 24th hour after reperfusion(P＜0.05).The activity of MPO in group N was significantly higher than that in group P at the 6th hour after reperfusion(P＜0.05).Compared with group N,the expression of TNF-αmBNA was reduced significantly in group P at the 2nd hour and 6th hour after reperfusion(P＜0.05).Conclusion Simultaneaus hepatic artery and portal revascularization can alleviate I/R induced bile duct injury of rat liver grafts,and the protective mechanism may be asseciated with inhibition the expression of TNF-α and decrease of neutrophil infiltration.

Objective To observe the effect of oral minirin in postoperative transsphenoidal surgery patients with central diabetes insipidus. Methods The changes in the urine volume and osomlality after two weeks of minirin medication (0. lmg, 3 times each day) were observed in 34 patients with central diabetes insipidus underwent transsphenoidal surgery. Results After two weeks of minirin therapy,the average daily urine volume decreased from 7985.40 ±410. 36 ml to 2277. 87 ± 328. 94 ml,and the average plasmas osmolarity increased from 301. 68 ± 3. 59 ml/d to 313. 26 ±4. 87 mOsm/ kg. No adverse reaction was observed during the therapy. Conclusions Minirin is effective and safe in the therapy of postoperative transsphenoidal surgery patients with central diabetes insipidus.

Objective To compare the sensitivity and specificity of NMP 22 test with voided urine cytology in detection of bladder cancer and to evaluate their clinical values. Methods For 155 patients suspected with bladder cancer NMP 22 and cytology were conducted in the same voided urine samples.Of them 95 patients with bladder transitional cell carcinoma were confirmed histologically.The sensitivity and specificity of NMP 22 and urine cytology were analyzed.60 patients without bladder cancer were selected as control. Results The overall sensitivity and specificity of NMP 22 test were 65.3% and 70.0%,respectively,those of urine cytology were 43.2% and 83.3%,respectively.There was no significant difference between the specificity of urine cytology and that of NMP 22 test;however,NMP 22 was significantly more sensitive than urine cytology in detection of any stages and grades of bladder cancer(P

As a new therapy in past twenty years,biological agents have been approved for the treatment of inflammatory bowel disease (IBD). However,biological agents currently used for IBD treatment require intravenous or subcutaneous injections,and some require infusion under close observation. Therefore,it is of positive clinical significance to find a safe and effective oral biological agent. This article reviewed recent advances in study on novel oral biological agents in the treatment of IBD.
