OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.
METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.
RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.
CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

Objective To explore the effect of Bailing capsule on epithelial-mesenchymal transition( EMT) in rats with adenine-in-duced tubulointerstitial fibrosis. Methods Tubulointerstitial fibrosis animal models were established and SD rats were divided into mo-del group ( n = 30), treatment group ( n = 30) and control group( n = 30), randomly. Experimental rats were harvested at 7 w, 12 w,17 w after onset of experiment and functional evaluations were performed. Histology, immunohistology were examined to investigateboth histolopathology changes and the expression of bone morphogenic protein-7 (BMP-7), transforming growth factor-β1 (TGF-β1 )and a-smooth muscle actin (α-SMA) in kidneys at three time points mentioned above, respectively. Results Compared with controlgroup, 24 h urinary protein in model group lost increasingly and significantly difference appeared at three time points relative to controlgroup ( P < 0.01 ). Urinary NAG in model group was markedly higher than that in control group from 7 w after onset (P < 0.01 ) andwas increasingly raised at 12 w and 17 w (P<0.01). The value of blood BUN and Cr in model group increased at 7 w (P>0.05) rel-ative to control group. There was significant difference at 12 w and 17.w (P < 0.01 ). Histologically, kidneys in model group, at 7 w,exhibited tubular casts and gently tubular dilation, granuloma in cortex, mononuclear cells infiltration in tubulointerstitial areas, andmild interstitial fibrosis. At 12 w, the degree of tubular injury and tubulointerstitial fibrosis gradually aggravated. Up to 17 w, diffusetubular dilation or atrophy was observed and focal tubules disappear. Diffuse interstitial fibrosis was exhibited. In normal kidneys, im-munohistochemistry suggested that the light expression of BMP-7 was detected in proximal renal tubular epithelial cells and marked ex-pression was identified in distal tubule, collecting duct, and renal tubular epithelial in junction area between cortex and medulla. How-ever, the expression of BMP-7 in kidneys of model group significantly decreased with increasing tubulointerstitial fibrosis and was nega-tive correlation with the expression of TGF-β1(r = -0. 981 P<0.01) and α-SMA (r= -0.975 P<0.01). Bailing capsule ad-ministration protected the expression of BMP-7 and reduced TGF-β1 and α-SMA expression before 12 w(P< 0.01 ). Conclusions Ourstudy shows an anti-fibrotic reno-protective function of Bailing capsule in rats with tubulointerstitial fibrosis via prevention of epithelial-mesenchymal transition at early stage. However, the beneficial effect lost with increasing tubulointerstitial fibrosis.
