Objective:To detect expression of SNCG and CXCR4 mRNA in gastric adenocarcinoma and evaluate its function in carcinogenesis, progression, infiltration, and metastasis, as well as the correlation of these proteins. Methods:The expression of SNCG and CXCR4 mRNAs was detected using reverse transcription-polymerase chain reaction in gastric adenocarcinoma and normal gastric mucosa. Results:The expression of SNCG and CXCR4 mRNAs was obviously higher in gastric adenocarcinoma than in normal gastric mucosa (P<0.01). The expression of SNCG mRNA was closely correlated with tumor infiltration depth (P<0.05) and lymph node metas-tasis (P<0.01). The expression of CXCR4 mRNA closely correlated with lymph node metastasis (P<0.01). The expression of SNCG and CXCR4 mRNAs positively correlated in 29 cases of gastric adenocarcinoma (r=0.346, P<0.05). Conclusion:SNCG and CXCR4 may be overexpressed in tumor tissue and may have important functions in tumorigenesis, progression, infiltration, and metastasis of gastric adenocarcinoma.

Objective To compare the different ways of alkaline mouthwash slobber use in preventing the oral infection in patients with fever. Methods The patients who satisfied the requirements were involved and randomly divided into A, B and C group. A group did not use alkaline mouthwash; B group prescribed alkaline mouthwash slobber following the doctor's advice; C group received propaganda and demonstration of intensive use of the alkaline mouthwash, and then used the slobber in right way under the surveillance of nurses. The infection rates of oral ulcer and oral leukoplakia were compared and analyzed among the three groups. Results The incidence rates of oral ulcer and oral leukoplakia gradually decreased among the three groups and the differences had statistical significance (χ2=9.243,P=0.010;χ2=6.495,P=0.033).Compared with A group, there was no significant differences in the rates of oral ulcers and oral leukoplakia between Group A and B(OR=0.486, 95%CI:0.113-2.087;OR=0.557, 95%CI: 0.120-2.583), but the incidence rates of oral ulcers and oral leukoplakia gradually decreased(OR=0.024, 95%CI:0.002-0.293;OR=0.036, 95%CI:0.003-0.448)in C group. Conclusions Strengthening use of alkaline mouthwash slobber is more effective in preventing oral infection in patients with fever compared with the routine way of mouthwash use.
