ABSTRACT
Objective To explore the factors related to the tolerance to enteral nutrition (EN) in gastric carcinoma patients undergoing surgical treatment and the implementation strategy of EN.Methods Fifty-four patients with gastric carcinoma undergoing surgery from November 2011 to September 2012 in the Affiliated Hospital of Medical College of Qingdao University were enrolled.EN were applied with sequential and gradual strategies.The tolerance status to EN was recorded.Factors related to the patient tolerance to EN were analyzed using single-factor and multiple-factor Logistic regression analysis.The incidences of gastrointestinal symptoms during EN application were recorded.Results Among the 54 patients,49 (90.74％) patients could tolerate EN.Single-factor analysis and multiple-factor Logistic regression analysis both showed that tumor staging (single-factor analysis:x2 =7.287,P =0.007 ; multiple-factor analysis:t =2.559,P =0.014) and surgical approach (singlefactor analysis:x2 =7.825,P =0.005 ; multiple-factor analysis:t =2.254,P =0.043) were major factors affecting patient tolerance to EN.Among the patients tolerant to EN,abdominal distension (19/49,38.8％) was the major gastrointestinal symptom of EN.Conclusion The sequential and gradual EN application strategy is suitable for the patients with gastric cancinoma after surgery,and can be widely used in clinical practice.
ABSTRACT
Objective To explore 18F-FDG PET-CT in the detection of malignant tumors of the gastrointestinal tract.Methods 39 patients with gastrointestinal tumors who was diagnosed with operation,pathological examination,clinical and imaging follow-up undertake the whole-body 18F-FDG PET-CT.Results The sensitivity and specificity were both 100.0 ％ for primary malignant tumors.Gastric metastases sensitivity,specificity and accuracy were 80.0 ％ (4/5),90.9 ％ (10/11),87.5 ％ (14/16),and the colorectal metastases sensitivity,specificity,accuracy of diagnostic results were 88.9 ％ (8/9),92.9 ％ (13/14),91.3 ％ (21/23).The gastric cancer lymph node metastasis sensitivity,specificity and accuracy were 50.0 ％ (3/6),90.0 ％ (9/10),75.0 ％ (12/16),in the diagnosis of colorectal local lymph node metastasis the sensitivity,specificity and accuracy were 71.4 ％ (5/7),93.8 ％ (15/16),87.0 ％ (20/23).Conclusion The 18F-FDG PET-CT imaging for gastrointestinal malignant tumor diagnosis and residual lesions recurrence or lesions metastases of detection is of important value and better than traditional examination methods.
ABSTRACT
The clinical implication of microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression in breast cancer and the relationship between them were studied. Specimens of 53 cases of breast cancer were examined for MVD in tumor and VEGF expression by using immunohistochemical staining. The results showed that the mean MVD in node-positive breast cancers and in the patients with postoperative distant metastasis was higher than that in node-negative breast cancers and those without metastasis, respectively (both P<0.01). The expression rate of VEGF in breast cancer was 67.92 % and was closely relative to MVD. It was suggested that MVD was closely correlated with metastasis of the tumors and might be a useful prognostic indicator for breast cancer. VEGF might be an important factor responsible for the induction of angiogenesis in breast cancer.
ABSTRACT
The serum contents of Cu, Fe, Zn, Pb, Cr, Mn, Ca, Mg, and K in 360 adults from different work in Nanjing were determined by atomic absorption spectrophotometry. The data were analysed by grouped statistical treatment, and the relationships among sex, age and work time were discussed. The results showed that serum Cu, Fe, Zn, Cr, Mn, Pb, Ca, Mg, K differed greatly in the different workers. There was a perfect positive correlations between Cu, Zn, Cd, Mn, Pb, Mg and age, and a negetive correlations berween Cu, Fe, Zn, Cd, Cr, Pb, Mg and work time. The serum Cu, Zn, Ca, K in women were higher than that in men.
