Objective:To investigate the relationship between Creactive protein(CRP)/albumin ratio (CAR) and lymph node metastasis of gastric cancer. Methods:A total of 96 cases of gastric cancer were included in the study. The clinical pathological stage and lymph node detection in patients with gastric cancer were analyzed, with the preoperative CAR as the dependent variable. Results:1) The pa-tients with preoperative CAR>0.04 has higher transfer rate and metastasis than the patients with preoperative CAR≤0.04, and the dif-ference was significant (P<0.05). The lymph node stage of patients with preoperative CAR>0.04 was significantly higher than that of the patients with preoperative CAR≤0.04, and the difference was significant (P<0.05). 2) The mean CAR of patients with Borrmann typesⅠ,Ⅱ,Ⅲ, andⅣgradually increased;with the progression of the pathological stage of gastric cancer, the mean value of CAR in-creased. 3) During the operation, the total number of lymph node dissections was high and the mean value of CAR before the opera-tion was high. Conclusion:The correlation between preoperative CAR and lymph node metastasis in patients with gastric cancer may reflect the degree of lymph node metastasis to a certain extent.

OBJECTIVETo study the link of Helicobacter pylori salive test cassette (HPS) and 13C-urea breath test (13C-UBT) on detecting Helicobacter pylori infection of stomach, and the sensitivity as well as specificity should be determined.
METHODSA screening trial of 13C-UBT and HPS tests was carried out 130 patients included 106 positive and 24 negative results of 13C-UBT. As gold standards of 13C-UBT, a comparison study with HPS was evaluated using Bayes formula.
RESULTSThe sensitivity, specificity, accuracy, positive and negative predictive value of HPS was 68.87%, 58.33%, 66.92%, 87.95%, 29.79% respectively. The coincidence was 66.92%.
CONCLUSIONThere is a correlation between results of 13C-UBT and HPS. Combination of 13C-UBT and HPS may compensate the blind zone of 13C-UBT in detecting oral Helicobacter pylori infection. 13C-UBT could not be used as a gold standard to judge the validation of HPS in detecting Helicobacter pylori oral infection. The methods can be used at the same time in clinic.
