[Long-Term Suppression with Short-Term Dose Reduction of Imatinib for Metastatic Lateral Lymph Nodes after Resection of a Rectal Gastrointestinal Stromal Tumor-A Case Report].

An 83-year-old female. At 82 years of age, the patient sought evaluation with a complaint of rectal bleeding. A 35-mm rectal gastrointestinal stromal tumor(GIST)was treated by laparoscopic ultra-low rectal resection and transanal anastomosis following trans-anal rectal dissection by perineal manipulation.

[Clinical verification of serum procalcitonin measurement in sepsis].

To evaluate the clinical application of measuring procalcitonin (PCT) level for diagnosis of bacterial sepsis in patients with and without systemic inflammatory response syndrome(SIRS), we studied the relationship between blood culture (BC) and serum PCT level in clinical 207 cases. In addition, we evaluated the time courses of PCT and other inflammatory markers: tumor necrosis factor-alpha (TNF-alpha), interleukin 6 (IL-6), E-selectin, WBC count and C-reactive protein (CRP) in 5 bacterial septic patients with SIRS. Serum PCT showed sensitivity of 41% and specificity of 61%, while BC showed specificity of 88%.
