Annexin A2 expression in intestinal mucosa of patients with inflammatory bowel disease and its clinical implications / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the role of annexin A2 (ANXA2) expression in the intestinal mucosa in the pathogenesis of inflammatory bowel disease (IBD).</p><p><b>METHODS</b>Intestinal or colonic mucosal biopsy samples were obtained from 54 patients with ulcerative colitis (UC), 37 with Crohn's disease (CD), and 15 healthy control subjects. Immunohistochemistry was employed to examine the expression of ANXA2 in the intestinal mucosa, and mRNA expression of ANXA2 was detected using real-time PCR.</p><p><b>RESULTS</b>Immunohistochemistry showed a ANXA2 positivity rate of 83.3% (45/54) in patients with UC, 27.0% (10/37) in patients with CD, and 53.3% (8/15) in the control subjects. ANXA2 expression in the intestinal or colonic mucosa was significantly up-regulated in patients with UC compared with the patients with CD and healthy control subjects, but was significantly lower in patients with CD than in the healthy controls (P<0.05). The expression levels of ANXA2 were strongly associated with the severity of clinical manifestations and the histopathological grades of UC (P<0.05). Compared with the healthy controls and patients with CD, patients with UC showed a significantly increased ANXA2 mRNA expression level in the inflamed mucosa of UC (P<0.05).</p><p><b>CONCLUSION</b>ANXA2 can serve as a marker for differential diagnosis of IBD, and its up-regulated expression is closely related to the pathogenesis of UC.</p>

Diagnosis and prognosis of 280 patients with pancreatic carcinoma / 中华胰腺病杂志

Objective To evaluate the factors influencing early diagnosis and prognosis in patients with pancreatic carcinoma.Methods The clinical data of 280 patients who had complete follow-up data with pancreatic carcinoma treated from January 2002 to January 2007 were reviewed retrospectively.The medical history and follow-up data were collected from all patients.Survival rate was calculated by the life table method and the Kaplan-Meier estimation.Log-rank test was used for univariate prognostic analysis and Cox regression was used for multivariate prognostic analysis.Results 91.8%of the patients were more than 40 years old and the peak age was 50～73 years old;the major presentations were abdominal pain and jaundice.Major imaging tests included B-ultrasound and CT,the sensitivity was 70.6%,95.3%,respectively;89.3%of patients had combined B-ultrasound and CT examination.The sensitivity of CA19-9 was 81.1%.The median survival time was(7.0±0.5)months.Overall survival rates at 1～5 year survival rates were 28%,9%,6%,2%,and 1%.Univariate analysis suggested that age＞65 years old,CA19-9＞mean value,TNM Ⅲ or Ⅳ stage,lymph nodes invasion,vascular invasion,and metastasis of two or more organs,non-surgical treatment,KPS score＜60 points,weight loss≥5 kg were poor prognostic factors;Cox multivariate analysis showed that treatment modalities,age,TNM stage,KPS score and ascites were independent risk factors for dismal prognosis.Conclusions The age,ascites,tumor stage and treatment modalities affected the prognosis of patients with pancreatic cancer.Early diagnosis and treatment was important to improve the survival time of patients with pancreatic cancer.
