Objective To investigate the expression levels and clinical significance of (forkhead box Q1) FOXQ1 and E-cadherin in esophageal squamous cell carcinoma (ESCC). Methods Expression levels of FOXQ1 and E-cadherin were in ESCC tissues (ESCC group, n=42) and adjacent normal esophageal tissues (control group, n=42) were detected using im?munohistochemistry. Correlations of FOXQ1 and E-cadherin expressions with clinical pathological parameters and progno?sis were analyzed between two groups. Results The expression level of FOXQ1 was significantly higher in ESCC group than that in control group(64.29% vs 28.57%,χ2=5.384,P<0.05). The expression level of E-cadherin was significantly lower in ESCC group than that incontrol group(52.38%vs 90.48%,χ2=7.691,P<0.05). There were significant differences in FOXQ1 expressions between different TNM stages and whether lymph node metastasis is involved within ESCC group. There were significant differences in expression of E-cadherin between different tumor differentiation, depth of invasion, TNM stage and whether lymph node metastasis is involved within ESCC group. The expression of FOXQ1 was negatively cor?related with E-cadherin in ESCC (r=-0.412, P<0.05). The 5-year survival rates were significantly lower with high expres?sion of FOXQ1 or with low expression of FOXQ1(18.52%vs 66.67%,χ2=9.737,P<0.05). The 5-year survival rates were significantly higher with high expression of E-cadherinor low expression of E-cadherin(59.09%vs 10.00%,χ2=10.996,P<0.05). A multivariate Cox's proportional hazard regression analysis indicated that high FOXQ1 expression, low E-cadherin expression and lymph node metastasis were independent prognostic factors for ESCC. Conclusion The expression of FOXQ1 and E-cadherin showed a good correlation with ESCC. And examining expressions of both FOXQ1 and E-cadherin in ESCC may have practical values in estimating the prognosis of ESCC and directing future treatment .

Objective To investigate the expressions of RhoB and E-cadherin in non-small-cell lung cancer (NSCLC), and their clinical significances thereof. Methods Immunohistochemical staining was applied to detect expres-sions of RhoB and E-cadherin in 116 samples of NSCLC (NSCLC group) and 116 samples of normal lung tissues (control group). Correlations of expressions of RhoB and E-cadherin to clinical pathological parameters and prognosis were analyzed in two groups. Results The expression intensities of RhoB and E-cadherin were significantly lower in NSCLC group than those in control group (57.76%vs 87.07%,54.31%vs 85.34%,P＜0.01). There were significant differences in the expres-sion of RhoB between different pathological types, differentiation and lymph node metastasis in NSCLC group. There were significant differences in the expression of E-cadherin between different TNM stages, differentiation and lymph node metas-tasis in NSCLC group. The expression of RhoB was positively correlated with the expression of E-cadherin ( r=0.503,P＜0.01). The 3-year survival rates were significantly higher in patients with high expression of RhoB (83.93%) than those in pa-tients with low expression of RhoB (40.00%, Log-rank χ2=18.992,P＜0.01). The 3-year survival rates were significantly higher in patients with high expression of E-cadherin (85.11%) than those in patients with low expression of E-cadherin (44.93%, Log-rankχ2=16.680,P＜0.01). Further multivariate analysis suggested that both lower expressions of RhoB and E-cadherin and lymph node metastasis were prognostic indicators for NSCLC (P＜0.001). Conclusion The expressions of RhoB and E-cadherin showed a good correlation in NSCLC. Detecting the expression of RhoB combined with E-cadherin may give a clue on clinicopathological features and prognosis in patients with NSCLC.

Objective To evaluate the efficacy and safety of chitosan in the repair of clinical surgery wounds.Methods The databases of Cochrane Controlled Trials Register (CCTR),Embase database,Medline database,PubMed database,CNKI database,WanFang database,VIP database and Chinese Biomedical Journal Library (CMCC) were retrieved with computer for collecting randomized controlled trials (RCT) about the repair clinical surgery wounds healing.Meta-analysis on all the data are carried out by RevMan 5.0 software.Results There were totally 16 trials and 3414 patients included.The results showed that the wound healing time ofchitosan was significantly shorter than that of the control group [WMD =-0.64,95％CI (-0.69～-0.59),P ＜ 0.000 01],and chitosan can better promote wound healing [RR =1.03,95％CI (1.01～1.04),P =0.0002].In experimental group,postoperativepain were reliever [WMD =-3.49,95％CI (-5.07～-1.91),P ＜ 0.0001],and postoperative infection were reduced [RR =0.49,95％CI (0.33～0.71),P =0.0002].Conclusion The existing evidences indicate that chitosan can shorten postoperative wound healing time,promote wound healing,relieve pain,and reduce infection.However,the study is limited by the quality of included literature,more clinical trials should be done to confirm the effective and safety.

Objective:To study the effects of andrographolide on the expression of IL-18 related cytokines by peripheral blood monocytes.Methods:After treatment of andrographolide in different concentrations on LPS stimulated human peripheral blood mononuclear cells (PBMC) and LPS+IFN-γ/IL-4 activated magnetic bead-sorted monocytes (PBM),the transcription level of IL-18,IL-18BP,IL-18Rα and IL-18Rβ was detected by real-time RT-PCR;and secreted IL-18,IL-18BP and IL-1β,IL-1Rα by PBM was detected with ELISA.Results:Andrographolide regulated the transcription of IL-18 and IL-18BP in a dose-and time-dependent effect.Andrographolide up-regulated the transcription of IL-18BP in LPS stimulated PBMC,and increased the ratio of IL-18BP/IL-18.The ratio of IL-18BP/IL-18 rose from 9.60 to 214 in LPS+IFNγ activated PBM,and IL-1Rα/IL-1β declined from 9 200 to 6 520 in IL-4 activated PBM by andrographolide treatment.Conclusion:Andrographolide can regulate IL-18 related gene transcription and expression in activated peripheral blood monocytes,and inhibit the excessive expression of IL-18 during inflammation.

Objective:To investigate the expression and clinical significance of cell division cycle 42 (Cdc42) and WASP family verprolin-homologous protein l (WAVE1) in non-small cell lung cancer (NSCLC). Methods:The expression of Cdc42 and WAVE1 was detected in 106 paraffin-embedded NSCLC tissues and 46 adjacent normal lung tissues (control group) using immunohistochemis-try. Results:The expression levels of Cdc42 and WAVE1 was distinctly higher in NSCLC than in the control group. The expression of Cdc42 in NSCLC significantly correlated with tumor differentiation, TNM stage, and lymph node metastasis (P<0.05). The expression of WAVE1 in NSCLC was significantly correlated with TNM stage and lymph node metastasis (P<0.05 or P<0.01). The expression of Cdc42 was significantly correlated with WAVE1 in NSCLC (r=0.469, P<0.01). The 3-year survival rates were significantly lower in the group with high Cdc42 expression (44.16%) than in the low expression group (72.41%;P<0.01). Similarly, the 3-year survival rates were significantly lower among patients with high WAVE1 expression (39.44%) than in those with low expression (77.14%;P<0.01). Lymph node metastasis and the common high Cdc42 and WAVE1 expression were independent prognostic factors for NSCLC. Conclu-sion:The Cdc42 expression is correlated with WAVE1 expression. They may act together and have an important function in NSCLC. The expression of both Cdc42 and WAVE1 in NSCLC tissue may be used as markers for assessing the clinicopathologic features and prognosis.
