BACKGROUND Studies on varicose veins have focused its effects on physical function;however,whether nonsurgical treatments alter muscle oxygenation or physical function remains ***,the differences in such functions between individuals with varicose veins and healthy individuals remain *** To investigate changes in physical function and the quality of life(QOL)following nonsurgical treatment of patients with varicose veins and determine the changes in their muscle oxygenation during *** We enrolled 37 participants(those with varicose veins,n=17;healthy individuals,n=20).We performed the following measurements pre-and post-nonsurgical treatment in the varicose vein patients and healthy individuals:Calf muscle oxygenation during the two-minute step test,open eyes one-leg stance,30 s sit-to-stand test,visual analog scale(VAS)for pain,Pittsburgh sleep quality index,physical activity assessment,and QOL *** Varicose veins patients and healthy individuals differ in most variables(physical function,sleep quality,and QOL).Varicose veins patients showed significant differences between pre-and post-nonsurgical treatment—results in the 30 sit-to-stand test[14.41(2.45)to 16.35(4.11),P=0.018],two-minute step test[162.29(25.98)to 170.65(23.80),P=0.037],VAS for pain[5.35(1.90)to 3.88(1.73),P=0.004],and QOL[39.34(19.98)to 26.69(17.02),P=0.005];however,no significant difference was observed for muscle *** Nonsurgical treatment improved lower extremity function and QOL in varicose veins patients,bringing their condition close to that of healthy *** studies should include patients with severe varicose veins requiring surgery to confirm our findings.

The current letter to the editor pertains to the manuscript entitled'Uridine diphosphate glucuronosyltransferase 1A1 prevents the progression of liver injury'.Increased levels of uridine diphosphate glucuronosyltransferase 1A1 during liver injury could mitigate damage by reducing endoplasmic reticulum stress,oxidative stress,and dysregulated lipid metabolism,impeding hepatocyte apoptosis and necroptosis.

Thioredoxin and thioredoxin-interacting protein as prognostic markers for gastric cancer recurrence

引用

World Journal of Gastroenterology 2012年第39期18卷 5581-5588页

作者： Jae Yun Lim Sun Och Yoo Soon won Hong jong won kim Seung Ho Choi Jae Yong Cho Department of Medical Oncology Gangnam Severance Cancer HospitalYonsei University College of MedicineSeoul 135-720South Korea Department of Pathology Gangnam Severance Cancer HospitalYonsei University College of MedicineSeoul 135-720South Korea Department of Surgery Gangnam Severance Cancer HospitalYonsei University College of MedicineSeoul 135-720South Korea

AIM:To evaluate the potential of thioredoxin (TXN) and thioredoxin-interacting protein (TXNIP) expression as biomarkers for predicting gastric cancer recurrence. METHODS:TXN and TXNIP expression levels were acquired from gene expression microarray data for 65 human gastric cancer tissues. We determined whether each gene expression level was associated with cancer recurrence and investigated the relationship between the two genes. For validation, the expression levels of TXN and TXNIP were measured by quantitative real- time reverse transcription polymerase chain reaction in 68 independent stage Ⅲ gastric cancer patients. The correlation between gene expression and cancer prognosis was evaluated. Immunohistochemical staining was performed to investigate the protein expression levels of TXN and TXNIP and to characterize the expression patterns of each protein. RESULTS:TXN was a prognosis-related gene (P = 0.009), whereas TXNIP, a TXN inhibitor, demonstrated a negative correlation with TXN in the gene expression microarray data. In the 68 stage Ⅲ patients, the expression levels of both TXN and TXNIP had a statistically significant effect on recurrence-free survival (RFS, P = 0.008 and P = 0.036, respectively). The low TXN and high TXNIP expression group exhibited a better prognosis than the other groups, and the high TXN and low TXNIP expression group exhibited a poorer prognosis (P < 0.001 for RFS and P = 0.001 for overall survival). More than half of the patients in the simulta-neously high TXN and low TXNIP expression group ex- perienced a recurrence within 1 year after curative surgery, and the 5-year survival rate of the patients in this group was 29%, compared with 89% in the low TXN and high TXNIP expression group. The TXN protein was overexpressed in 65% of the gastric cancer tissues, whereas the TXNIP protein was underexpressed in 85% of the cancer cells. In a correlation analysis, TXN and TXNIP were highly correlated with many oncogenes and tumor suppressors

World Journal of Gastroenterology 2012年第1期18卷 49-54页

作者： jong won kim Jae-Ho Cheong Woo Jin Hyung Seung-Ho Choi Sung Hoon Noh Department of Surgery Gangnam Severance Hospital Yonsei University College of Medicine Department of Surgery Severance Hospital Yonsei University College of Medicine

AIM: To evaluate the prognosis of type Ⅱ diabetes mellitus (T2DM) after gastrectomy and related factors in gastric cancer patients. METHODS: 403 gastric cancer patients with T2DM were studied, who underwent gastrectomy between May 2003 and September 2009. A review of medica records and telephone interviews was performed in this cross-sectional study. The factors included in the statistical analysis were as follows: gender, age, type of surgery, preoperative body mass index (BMI), current BMI, BMI reduction ratio, preoperative insulin or oral diabetic medicine requirement, follow-up duration, and current state of diabetes. Assessment of diabetes status after surgery was classified into four categories according to the change in hypoglycemic agents after surgery and present status of T2DM: resolution, improvement, same, and worse.(± 20.6 mo), preoperative BMI was 24.7 kg/m2 (± 3.0 kg/m2), and BMI reduction ratio was 9.8% (± 8.6%). After surgery, T2DM was cured in 58 patients (15.1%) and was improved in 117 patients (30.4%). According to the type of surgery, the BMI reduction ratio was signif icantly higher in the total gastrectomy and Roux-en-Y reconstruction group [14.2% ± 9.2% vs 9.2% ± 7.7% (Billroth Ⅱ group), P < 0.001] and signif icantly lower in the subtotal gastrectomy and Billroth Ⅰ reconstruction group [7.6% ± 8.0%, 9.2% ± 7.7% (Billroth Ⅱ group), P < 0.001]. The BMI reduction ratio, follow-up duration after surgery, type of surgery, extent of gastrectomy, and performance of duodenal bypass were signif icantly correlated to the course of T2DM (P < 0.05). The BMI reduction ratio was the most influential factor on T2DM status. In a subgroup analysis of patients with a BMI reduction ratio of 10% or less (n = 206), T2DM was cured in 15 (7.6%) patients and was improved in 57 (28.8%) patients after surgery, and only the duration of surgery was signif icantly correlated to T2DM status (P = 0.022).
