RESUMO
Objective@#To introduce a combined operation for treating chronical peroneal tendon dislocation and to evalu-ate the clinical outcomes of patients.@*Methods@#Data of 12 ankles in 12 patients (male 9, female 3) with chronical peroneal ten-don dislocation who underwent the fibular groove deepening procedure with transposition of the peroneal longus muscle from June 2006 to August 2013 were retrospectively analyzed. The mean age was 24.6±4.3 years (range, 18-34 years), and there were 3 cas-es on left side, 9 on right side. The mechanism of peroneal tendon injury consisted of sports injuries in 8 and sprains in 4. There were 8 cases of flat fibula sulcus and 4 cases of convex. All patients met the inclusion criteria of a painful snapping or popping sen-sation or palpable clicking and positive provocation maneuver and without fracture and were treated with peroneal sulcus deepen-ing and peroneal longus tendon transposition. The duration of preoperative popping and pain symptoms ranged from 12 to 23 weeks, with an average of 16.9±4.0 weeks. All cases were treated conservatively 3-4 weeks before operation and were not effec-tive. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, visual anologue scale (VAS).@*Results@#Twelve patients were followed up with an average period of 37.3±7.0 (range, 25-50) months. The mean VAS scale score of all patients reduced from 5.6±0.9 to 0.5±0.7 at the latest follow-up. The mean AOFAS scale score improved from 61.4±5.6 to 92.6±4.2 at the latest follow-up. The difference between preoperative and postoperative was statis-tically significant. (t=16.250,-18.475; P=0.000). According to the evaluation of symptom and function scoring system, 10 cases were excellent and 2 cases were good, with an excellent rate of 100%. The mean postoperative return-sport time was 26.42±3.06 weeks (range, 23-32 weeks). All patients healed primarily and no infection, skin necrosis and residual redislocation occurred. The osteotomy healed completely without displacement, which was confirmed by imaging examination in three months postoperation. No patients had intractable pain after surgery, and they were able to perform daily activities at 3 months and physical exercise at 6 months after surgery. No slip occurred in all patients at the latest follow-up.@*Conclusion@#The fibular groove deepening procedure with transposition of the peroneal longus muscle can effectively treat chronical peroneal tendon dislocation and obtain good medi-um-term results.

RESUMO
Objective To compare and analyze the epidemiological features of fractures at the base of the first metacarpal bone between East and West China.Methods We retrospectively analyzed the clinical data of the patients with fracture at the base of the first metacarpal bone who had been treated from January 2010 to December 2011 in 63 hospitals in the east and west areas of China.The data from 35 hospitals in East China were classified as group A while the data from 28 hospitals in West China as group B.The analytic items included gender,age,age distribution and fracture classification.Results A total of 890 cases were collected.The total male/female ratio was 4.56∶ 1.The youth accounted for the highest proportion and the high-risk type of fracture was type Ⅲ (44.49％,396/890).The male/female ratio was 4.59∶1 in group A of 621 patients and 4.49∶1 in group B of 269 patients,showing no statistic between-group difference (P ＞ 0.05).The median age in group A was 39 years,significantly older than that in group B (35 years) (Z =-3.687,P ＜ 0.001).In both groups,the youth accounted for the highest proportion and there were more right-side fractures than left-side ones.Group A had a significantly lower proportion of the youth and a significantly higher proportion of the middle-aged than group B (P ＜ 0.05),but there was no statistic difference in proportions of the children and the aged (P ＞ 0.05).Type Ⅲ was the high-risk type in both groups;group A had significantly more fractures of type Ⅰ and significantly fewer fractures of type Ⅱ than group B (P ＜ 0.05),but there was no statistic difference in proportions of type Ⅲ and type Ⅳ between the 2 groups (P ＞ 0.05).Conclusions Fractures at the base of the first metacarpal bone mostly occurred in the young males.There were more fractures at the right side than at the left side.The most frequent type was type Ⅲ.The proportion of type Ⅰ fractures in East China was higher than in West China while the proportion of type Ⅱ fractures in East China lower than in West China.

RESUMO
Objective To analyze the epidemiological features of Galeazzi fractures from 2003 through 2012 in The Third Affiliated Hospital to Hebei Medical University. Methods We retrospectively analyzed the data of Galeazzi fractures between January 2003 and December 2012 in the Third Affiliated Hospital to Hebei Medical University. The data from 2003 through 2008 were defined as group A and those from 2008 through 2012 as group B. The general information was compared between the 2 groups. The epi-demiological characteristics and trends during the 10 years were analyzed concerning gender, age and fracture type of the patients. Results A total of 153 Galeazzi fractures were recorded, accounting for 0. 81％ of ulnoradial fractures and 0. 12％ of all fractures. There were 109 males and 44 females, with a male/female ratio of 2. 48:1. The age range from 11 to 20 years had the highest constituent ratio ( 22. 22％) and type Ⅱthe highest proportion ( 76. 47％) . There were 74 cases in group A, with a male/female ratio of 2. 22:1. There were 79 cases in group B, with a male/female ratio of 2. 76:1. There was no significant difference between the 2 groups concerning the male/female ratio ( P > 0. 05 ) . The median age for group A was 29 years, significantly younger than that for group B ( 34 years ) ( P 0. 05 ) . Conclusions Galeazzi fractures accounted for 0. 81％ of ulnoradial fractures and 0. 12％ of all fractures. There were more male patients than female ones. The age range from 11 to 20 years and typeⅡhad the highest constituent ratios. Compared with the first 5 years, the latter 5 years witnessed increased mean age.

RESUMO
Objective To investigate the expression of VEZT and its clinical pathological significance in gastric cancer tissues,and to construct the VEZT over-expression vector.Methods The expression of VEZT was examined in 119 cases of gastric carcinoma and their corresponding normal mucus tissues by SP immunohistochemical staining.The relationships between the VEZT expression levels and its clinicopathological characteristics,prognosis were also investigated.VEZT cDNA was extracted and amplificated from 293 cells by polymerase chain reaction (PCR).Using DNA recombinant technique,the target gene was connected to the pEGFP-N1 vector to construct recombinant plasmid vector after the target gene and pEGFP-N1 were purified.The recombinant plasmid was identificated by 1％ enzyme electrophoresis and DNA sequencing.Results The VEZT-positive expression in gastric carcinoma was 30.3％ and 60.5％ in normal gastric tissues.VEZT expression in high differentiated cancer tissues was higher than that in lower differentiated tissues(x2 =5.002,P ＜ 0.05),expression of VEZT in early gastric cancer was significantly higher than that in patients with advanced gastric cancer (x2 =5.551,P ＜ 0.05),expression of VEZT in patients without lymph node metastasis was significantly higher than that of lymph node metastasis (x2 =5.878,P ＜ 0.05).Patients with positive VEZT expression have better prognosis than the negative patients(x2 =6.908,P ＜ 0.01).The target fragment,consistent with the theoretical value,was verified by gel electrophoresis.DNA sequencing confirmed that the gene sequence had no mutation and the eukaryotic expression plasmid vector pEGFP-N1-hVEZT was successfully constructed.Conclusions VEZT protein was correlated with TNM staging,tumor stage,invasion depth and lymph node metastasis,positive VEZT expression predicting better five year survival.The VEZT over-expression plasmid vector was successfully constructed.
