  • Ultrasound Guided Needle Aspiration and Cavity Washing Versus Incision and Drainage to Treat The Breast Abscesses—Meta Analysis

    ObjectiveTo evaluate the clinical effect of ultrasound guided puncture irrigation and traditional incision and drainage in the treatment of breast abscess. MethodsCNKI, Wanfang Database, CBM, PubMed, Cochrane Library, Web of Science, and EMbase were searched, at the same time complementary with other retrieval in any language to collect the randomized controlled trials (RCTs) about comparison ultrasound guided needle aspiration with incision and drainage to treat the breast abscesses published by late August, 2015. Data related to clinical outcomes were extracted by two reviewers independently. Statistical analyses were carried out using RevMan5.3 software. ResultsEight studies were included, which involving 373 participants according to the inclusion criteria. The differences were statistically significant about the cure rate [OR=2.51, 95% CI (1.47, 4.28), P=0.000 8〕, effective rate [OR=7.45, 95% CI (2.29, 24.27), P=0.000 9〕, the heeling time [SMD=-1.77, 95%CI (-2.09, -1.44), P < 0.000 01〕, the length of the scar [MD=-2.88, 95% CI (-3.43, -2.33), P < 0.000 01〕, and the complications [OR=0.18, 95% CI (0.05, 0.62), P=0.007〕. Conciusions Compared with traditional methods of incision and drainage, ultrasound guided needle aspiration and wash has the more cure rate, the more effective rate, the less heeling time and scars as well as complications.

  • Expressions and Clinical Significance of Chemokines Factor Receptors 4 and Chemokines Factor Receptors 7 in Gastric Cancer Tissues

    ObjectiveTo investigate the expressions and significance of chemokines factor receptors 4 (CXCR4) and chemokines factor receptors 7 (CXCR7) in gastric cancer tissues. MethodsSixty-five patients with gastric cancer who treated in our hospital from January 2011 to June 2013 were retrospectively collected as gastric cancer group, and 20 patients with gastric ulcer were retrospectively collected as control group at the same time. The expressions of CXCR4 and CXCR7 in gastric cancer tissues and normal gastric tissues were measured by immunohistochemistry, and then the relation-ship among expressions of CXCR4/CXCR7 in gastric cancer tissues and clinicopathological features of patients with gastric cancer was explored, as well as its effect on survival. ResultsPositive expression rates of CXCR4 and CXCR7 were identi-fied in 80.00% (52/65) and 84.62% (55/65) of the gastric cancer group, and 5.00% (1/20) and 10.00% (2/20) in control group respectively, and the positive expression rates of CXCR4 and CXCR7 in gastric cancer group were significantly higher than those of control group respectively (χ2=36.65, P<0.01; χ2=38.55, P<0.01). The positive expression rate of CXCR4 in gastric cancer tissues was related with degree of differentiation, T staging, and TNM staging (P<0.05), positive expression rate of CXCR4 in patients with poor differentiation, T3-4 staging, and TNM Ⅲ-Ⅳ staging were higher than corresponding patients with moderate/high degree of differentiation, T1-2 staging, and TNM Ⅰ-Ⅱ staging. The positive expression rate of CXCR7 in gastric cancer tissues was related with degree of differentiation, T staging, and N staging (P<0.05), positive expression rate of CXCR7 in patients with poor differentiation, T3-4 staging, and N1-3 staging were higher than corrsponding patients with moderate/high degree of differentiation, T1-2 staging, and N0 staging. The survival situation was worse in patients with positive expression of CXCR4 and CXCR7 than corresponding patients with negative expression (P=0.01, P=0.01) respectively. ConclusionsCXCR4 and CXCR7 are related to gastric cancer genesis and development. Furthermore, the expressions of CXCR4 and CXCR7 could be used as markers to predict prognosis of gastric cancer. The regulation of CXCR4/chemokine ligand 12 (CXCL12) axis and CXCR7/CXCL12 axis may provide a new targeted therapy for patients with gastric cancer.
