BACKGROUND:Manual reduction for external fixation of distal radius fractures can achieve good outcomes. OBJECTIVE:To carry out the bibliometric analysis on manual reduction for external fixation of distal radius fractures. METHODS:Literatures concerning reduction for external fixation of distal radius fractures were retrieved in CNKI database from 2003 to 2012. The keywords were“external fixation;distal radius fractures”. Duplicate and irrelevant articles were eliminated, and a total of 408 articles were retrieved. A bibliometric analysis of these 408 articles was performed in terms of publishing time and number, subject categories, source journals, research institutions, times cited and download frequency. RESULTS AND CONCLUSION:Literatures concerning manual reduction for external fixation of distal radius fractures exhibit an upward trend in number. In 2012, there were 85 relevant articles. In the past 10 years, 18 relevant articles have been published in Chinese Journal of Traditional Medical Traumatology&Orthopedics, which is the most. There are not many relevant studies in various research units, only 1-7 articles published per unit, and five articles are funded.

Surgical treatment of gastric cancer concurrent with portal hypertension / 中华普通外科杂志

Objective To evaluate the surgical approaches for gastric carcinoma accompanied by portal hypertension ( PHT).Methods The clinical data of 22 patients with PHT undergoing operation during 5 years were retrospectively analyzed.The liver function was Child's A in 12 cases, Child's B in 10 cases.Total gastrectomy + pericardial devascularization was performed in 11 cases, distal subtotal gastrectomy in 9 cases, distal subtotal gastrectomy + splenectomy in one, distal subtotal gastrectomy + pericardial devascularization in one.12 cases with Child's A underwent D2 lymph node (LN) dissection and 10 cases with Child's B were treated with D1 LN dissection.Liver biopsy was taken in all patients.Results Postoperative complications developed in 50% and mortality rate was 9%.The rate of liver function deterioration in patients of Child A ungergoing D2 lymph node dissection was 42% , and that of patients with Child B was 70%.The rate of postoperatiave complications in patients with Child A ungergoing D2 lymph node dissection was 25% , while that of patients with Child B was 80%.There was no significant difference in liver function deterioration rate between Child A and Child B (P ＞ 0.05) , but the rate of postoperative complications in Child A is much lower than those in Child B(P ＜ 0.05).The complication rate in patients receiving PHT targeting measures was 77% ,much higher than 11% in those without concurrent treatment of PHT ( P ＜ 0.05 ).Conclusions Individualized surgical approache is crucial for treatment of gastric carcinoma accompanied by PHT.Surgical treatment should be on the basis of liver function and the severity of PHT.
