RESUMEN
BACKGROUND/AIMS: This study aimed to evaluate the efficacy of modified Roux-en-Y gastric bypass for type 2 diabetes mellitus. METHODOLOGY: Forty-five type 2 diabetes mellitus patients underwent modified Roux-en-Y gastric bypass at WeiFang People's Hospital. Data on patient demographics, fasting plasma glucose (FPG), body mass index (BMI), medication use, remission and hemoglobin A1c (HbAlc) were prospectively collected and analyzed. RESULTS: At 6 months after surgery, all of these 45 patients obtained remission or a marked improvement. FPG was in the normal range in 39 (86.7%) patients stopping medicine treatment for their diabetes. Six patients (13.3%) had an obvious reduced abnormal FPG and they only required lower drug dosage. No statistically significant differences were found between the obese or non-obese groups (p=0.311). The mean BMI dropped from 28.9±3.0 kg/m2 to 27.4±2.8 kg/m2 (p=0.000) at the third month and 26.3±2.5 kg/m2 (p=0.000) at the sixth month. HbAlc decreased from their preoperative values of 7.4%±2.2% to 6.3%±1.5% (p=0.000) at the third month and 5.1%±0.9% (p=0.000) at the sixth month. CONCLUSIONS: Modified Roux-en-Y gastric bypass was effective in treating type 2 diabetes mellitus, independent of body mass index.

OBJECTIVES: To investigate the diagnostic accuracy of ultrasound for evaluation of inflammatory activity in patients with Crohn's disease (CD). Methods: Fifty-six patients with histologically proven CD (39 with active, 17 with inactive disease) and 30 healthy volunteers as a control group were enrolled in the study at WeiFang People's Hospital, Weifang Province, China from October 2012 to December 2014. Bowel wall thickness, and vascularity pattern were measured by Doppler ultrasound. Results: There was a significant difference in flow volume of the superior mesenteric artery (585 ± 235 ml/min) in the patients with active disease, compared with those with inactive disease (401 ± 238 ml/min) and the control group (390 ± 189 ml/min, p less than 0.001). Wall thickness was 5.1 ± 1.5 mm in the active CD group, 3.3 ± 1.6 mm in the inactive disease group (p less than 0.001) and less than 3 mm in the control group. Resistance index in the thickened bowel wall showed some differences: 0.68 ± 0.05 in the active disease group, 0.78 ± 0.08 in the inactive disease group, and 0.85 ± 0.07 in the control group (p less than 0.05). Conclusion: Doppler ultrasound is a useful diagnostic tool in detecting CD and assessing inflammatory activity.

AIM: To investigate the expression of annexin A5 in serum and tumor tissue of patients with colon cancer and to analyze its clinical significance. METHODS: Ninety-three patients with colon cancer treated at our hospital between February 2013 and March 2016 were included in an observation group, and 40 healthy individuals were included in a control group. Enzyme-linked immunosorbent assay was performed to determine the serum level of annexin A5, while immunohistochemistry was performed to determine the expression of annexin A5 in cancer tissues. RESULTS: The serum level of annexin A5 was 0.184 ± 0.043 ng/mL in the observation group, which was significantly higher than that in the control group (P < 0.05). Annexin A5 expression was detected in 79.31% of the patients with lymph node metastasis, which was significantly higher than that in patients without lymph node metastasis (P < 0.05). Moreover, annexin A5 expression was detected in 86.96% of the patients with stage III to IV disease, which was significantly higher than that in patients with stageâI to II disease (P < 0.05). The serum level of annexin A5 was 0.215 ± 0.044 ng/mL in patients whose tumors were positive for annexin A5 expression, which was significantly higher than that in patients whose tumors were negative for annexin A5 expression (P < 0.05). The serum level of annexin A5 was correlated with annexin A5 expression in colon cancer tissues (r = 0.312, P < 0.05). When a cutoff value of > 0.148 ng/mL for serum level of annexin A5 was used in the diagnosis of colon cancer, the sensitivity was 83.90%, and the specificity was 57.50%. CONCLUSION: For patients with colon cancer, annexin A5 expression in cancer tissues is related to lymph node metastasis and tumor grade. Serum level of annexin A5 is related to annexin A5 expression in cancer tissues and is of diagnostic relevance.
