  • Classic Citation Analysis on Surgical Treatment for Type 2 Diabetes

    Objective To analyze the citation classics articles, and approach the research development history and the research direction in the future about surgical treatment for type 2 diabetes. Methods The most frequently cited articles had published in Social Sciences Citation Index database by the end of October 30, 2012 were retrieved. The 50 most frequently cited articles were selected. Articles were evaluated for several characteristics, including number of citations, publication time, country of origin, institution, journal, publication type of article, and authorship. Results The most frequently cited article received 1 751 citations and the least frequently cited article received 73 citations, with a mean of 242.76 citations per article. These citation classics were published in 18 high-impact journals, led by Annals of Surgery and Obesity Research as 10 papers. Of the 50 articles, 18 articles were clinical observational study, 20 articles concerned basic science, 10 articles were review articles, and 2 articles were commentary. These citation classics were published from 1990 to 2009, most of them (40) from 2000 to 2009. Three institutions produced 2 top-cited articles, including Medical College of Virginia, Monash University, and East Carolina University. These articles originated from 14 countries, the top was USA (22 articles). Two persons authored 3 published papers (Cummings DE and Rubino F). Conclusion Most “citation classics” in research about surgery for type 2 diabetes are observational studies published in high-impact journals by US-based authors after 1990.

  • Mechanism Study Progress of Gastrointestinal Bypass Operation on Treatment of Type 2 Diabetes Mellitus

    Objective To study the mechanism of gastric bypass operation on treatment of type 2 diabetes mellitus, recognize the etiology and pathogenesy of the disease and frame therapy strategy for type 2 diabetes mellitus. Methods The literatures about gastric bypass operation on treatment of type 2 diabetes mellitus, including clinical cases reports and evidence-based studies were reviewed. Results Gastrointestinal bypass operation was regarded as an effective treatment for type 2 diabetes mellitus. There were three hypotheses of therapy mechanism: early delivery of nutrients to the distal intestine, exclusion of the proximal intestine and incretin/anti-incretin. Conclusion Gastrointestinal bypass operation is now considering as an effective treatment, there is still a lack of basic experimental studies to clarify the mechanism.

  • Caveolin-1 Inhibits Proliferation of Pancreatic Carcinoma Cells Through Suppressing Activation of PI3K/Akt Signaling Pathway

    ObjectiveTo investigate the effect and mechanism of caveolion-1 on the growth and proliferation of human pancreatic carcinoma cell Panc1, in vitro. MethodsThe plasmid pCI-neo-cav-1 and its corresponding empty vector (pCI-neo) were transfected into Panc1 cell line (study group and control group, respectively). Expressions of caveolin-1, Akt, and Aktphosphate (p-Akt) were determined in transfectants by Western blot analysis. The cell growth curve was drawn and the double time was calculated in each group, and the cell cycle was analyzed by flow cytometry. The colony formation ability of tumor cells was detected by anchorageindependent growth assay. ResultsCaveolin-1 expression was up-regulated (Plt;0.01) and the growth of Panc1 cell was inhibited significantly (Plt;0.01) in the study group comparing with the control group. Caveolin-1 overexpression inhibited proliferation of Panc1 cell by arresting the cell cycle in the G0/G1 phase (Plt;0.05), the rate of S phase in the study group was lower than that of the control group (Plt;0.01). Proliferation index of the study group was also lower than that of the control group (Plt;0.01). Caveolin-1 overexpression reduced the capacity of the cells to form colonies in soft agar (Plt;0.01). p-Akt protein was reduced in the study group as compared with the control group (Plt;0.05). ConclusionCaveolin-1 can function as a cancer suppressor through inhibiting the activation of PI3K/Akt signaling pathway in Panc1 cell.

  • Treatment for Liver Cancer by Operation with Bipolar Radiofrequency-Assisted Device or Monopolar Radiofrequency-Assisted Ablation

    Objective To analyze the application of bipolar radiofrequency-assisted device or monopolar radiofre-quency-assisted ablation in treatment for liver cancer by operation. Methods From June 2008 to May 2012, 56 patients with liver cancer underwent operation with bipolar radiofrequency-assisted device (Habib group, n=22) or monopolar radiofrequency-assisted ablation (mRFA group, n=34) were selected retrospectively. The operation time, postoperative morbidity, hospital stay, hospital costs, intraoperative bleeding, and therapeutic effects were compared in two groups. Results The percentage of patients with liver cirrhosis was 85.7% (48/56), with multiple tumors was 12.5% (7/56), underwent laparoscopic operation was 16.1% (9/56). Patients with the tumor diameter greater than 5 cm in the Habib group were more than that in the mRFA group (P=0.000), the laparoscopic surgery proportion had no significant difference in two groups (P=0.074). ① The intraoperative bleeding in the Habib group was more than that in the mRFA group (P=0.000). Two patients were adopted a hepatic portal blocking and 3 patients with intraoperative blood transfusion in the Habib group. ② The operation time in the Habib group was longer than that in the mRFA group (P=0.021), but there was no difference of the operation time in two groups patients with tumor diameter greater than 5 cm (P=0.191). ③ The postoperative morbidity had no obvious difference in two groups 〔18.2% (4/22) versus 11.8% (4/34), P=0.780〕. ④ Thehospital stay and the hospital costs in the Habib group were significantly more than those in the mRFA group (P=0.001, P=0.004).⑤The tumor residuals were found in two patients with tumor diameter greater than 5 cm. Conclusions Treatment for liver cancer by operation with bipolar radiofrequency-assisted device or monopolar radiofrequency-assisted ablation is safe and effective. The monopolar radiofrequency-assisted ablation has advantages of less intraoperative bleeding, more minimal invasion proportion, less hospital stay and hospital costs for liver cancer patients with small tumor (diameter<3 cm), multifocal tumors and minimal invasion conditions as compared with bipolar radiofrequency-assisted device. Operation with bipolar radiofrequency-assisted device in patients with larger tumors (diameter≥5 cm) resection might be a better choice.
