Objective: To investigate the association of periodontal diseases in pregnant women with preterm birth and low birth weight. Methods: 213 pregnant women aged 22-40 years were enrolled while receiving periodontal examination by 26 weeks of gestation. Periodontal measurements included plaque index(PLI),bleeding on probing (BOP),probing pocket depth(PD) and clinical attachment loss(CAL) were used as the criteria to classify the groups: healthy group(HG; n = 63),gingivitis group(GG; n = 74) and periodontitis group(PG; n = 76). At delivery,birth date and birth weight were recorded. Results: Preterm birth ratio in PG group is higher than that in HG group and GG group(P < 0. 05). Conclusion: Periodontal disease may lead to preterm birth in pregnant women.

Objective To observe the expression levels of CD174, cyclin D1 and cyclin E in gastrointestinal tumor tissues, analyze the correlation among CD174, cyclin D1 and cyclin E, and evaluate the expression level of CD174 for diagnosis and prognosis of gastrointestinal tumors.Methods Flow cytometry was used to determine the expression of CD174, cyclin D1 and cyclin E on surface of the cells which were collected from the tumor tissues and distant part beside the same tumor and suspended. The expression and topography of CD174 in gastrointestinal tissue were investigated with immunohistochemical staining.Results The expression of CD174 in tumor tissues was obviously lower than that in distal noncancerous tissues (P
