Abstract: To investigate the status and influencing factors of tooth loss among the elderly population in China, so as to provide insights into early prevention of tooth loss. Methods: Based on the Chinese Longitudinal Healthy Longevity Survey (CLHLS), data of the elderly people aged 65 years and older who participated in the survey in 2018 were collected, including demographic information, lifestyle, dietary habits, medical history, number of teeth remaining and self-assessment indicators. The status of tooth loss among the elderly were described based on the standard of 28 teeth, and factors affecting tooth loss were analyzed using a multivariable ordinal logistic regression model. Results: A total of 5 260 people was recruited, including 3 346 males (63.61%) and 1 914 females (36.39%). The median age was 78.00 (interquartile range, 18.00) years. The median number of teeth remaining was 12.00 (interquartile range, 23.00), and the median number of missing teeth was 16.00 (interquartile range, 23.00). Multivariable ordinal logistic regression analysis showed that the elderly who were female (OR=1.270, 95%CI: 1.098-1.470), had advanced age (OR=1.090, 95%CI: 1.083-1.098), lived in rural areas (OR=1.369, 95%CI: 1.165-1.610) and urban areas (OR=1.208, 95%CI: 1.027-1.422), smoked (past, OR=1.471, 95%CI: 1.240-1.746; always, OR=1.545, 95%CI: 1.300-1.838) and brushed teeth less than once a day (OR=1.791, 95%CI: 1.488-2.160) had more missing teeth; while the elderly who had high levels of education (junior high school, OR=0.819, 95%CI: 0.681-0.972; high school, OR=0.626, 95%CI: 0.507-0.771; college and above, OR=0.468, 95%CI: 0.334-0.657), kept physical exercise (OR=0.840, 95%CI: 0.736-0.958) and were overweight/obese (OR=0.868, 95%CI: 0.769-0.980) had less missing teeth. Conclusion Gender, age, residence, educational level, smoking, physical exercise, teeth brushing frequency and overweight/obese are the influencing factors for tooth loss among the elderly in China.

Objective: To investigate the survival and individualized therapy of metastatic colorectal cancer (mCRC) patients who achieved a stable disease state after induction chemotherapy. Methods:Data were reviewed from 204 metastatic colorectal cancer pa-tients, who presented a stable disease state after first-line and second-line chemotherapy at Tianjin Medical University Cancer Insti-tute and Hospital. The clinical and pathological characteristics were analyzed. Moreover, we analyzed the significance of maintenance treatment in patients with certain mCRC characteristics. Results:Univariate analysis indicated that the line of chemotherapy, levels of CA724, CEA, and CA19-9, and platelet-to-lymphocyte ratio (PLR) were considered prognostic factors of treatment after induction che-motherapy. According to the multivariate analysis, first-line chemotherapy, as well as low levels of CA19-9 and PLR, with maintenance treatment after the induction chemotherapy was significantly associated with better survival. Among the patients with high levels of PLR, those who underwent maintenance treatment achieved a progression-free survival of 13.43 months (versus 10.63 months in pa-tients from the observation group, P=0.003). Conclusion:The levels of CA19-9 and PLR, and treatment after chemotherapy were signif-icant prognostic factors for mCRC patients who achieved a stable disease state after induction chemotherapy. These patients, especial-ly those with high PLR, could benefit from the maintenance treatment.

OBJECTIVE:To strengthen the supervision of clinical antibiotics use through establishing electronic consultation system. METHODS:Based on hospital information system(HIS)and antibiotic management system,consultation system for anti-biotics of special use(ASU)was established,and the effects of the system after used(Jan. 2014)were also evaluated. RESULTS:Real-time consultation of ASU medical orders and related consultation results inquiry and statistics could be achieved through de-signing ASU consultation application form,establishing consultation experts and confirming their working content,adding statistics function,etc. The consultation have been finished 8275 times from 2014 to 2015. The inspection rate for pathogenic microbes in ASU patients rose from 78.68% in 2013 to 83.90% in 2015. CONCLUSIONS:The establishment and application of ASU consulta-tion system can improve consultation efficiency and quality,so as to promote rational use of antibiotics in the clinic.

Methods The oleic acid ALI mouse model was built to dynamically observe the binding capacity and the binding affinity of glucocorticoid receptor(GR),the levels of GR,heat shock protein 90(Hsp90)and Hsp70 before and after hyperthermic stress pretreatment. Results Heat stress pretreatment had significant protective effect on ALI.Western blotting showed insignificant changes of GR levels but progressive increase of level of Hsp70 and Hsp90.Heat stress pretreatment exerted insignificant effect on Bmax and Kd of GR,shown by radio ligand binding assay after ALI. Conclusion The protective effects of heat stress pretreatment on ALI of mouse may relate to its ability of keeping stable GR level and increasing levels of Hsp70 and Hsp90.

Objective To explore the role of H19 imprinting in etiology of pre-eclampsia. Methods Placentas of 24 women with pre-eclampsia (3 with mild pre-eclampsia and 21 with severe pre-eclampsia) and 50 healthy pregnant women at full term (control) were collected during selected cesarean delivery between August 2007 and March 2008. The statuses of H19 imprinting with placental tissues from normal pregnancy and patients with pre-eclampsia were identified upon polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The systolic and diastolic pressure were analyzed in H19 heterozygotic women. Results (1) There were 20 (40%) heterozygotes in 50 cases placenta tissues of the third trimesters, 11 (45%) heterozygotes in 24 cases placenta tissues of pre-eclampsia, There were no significant difference between two groups ( P > 0.05 ). (2) All 20 heterozygotes in placenta tissues of the third trimesters are exclusively monoallelically expressed, while 5 cases (45%) in 11 heterozygotes of pre-eclampsia are biallelically expressed (loss of imprinting, LOI). There were significant difference between two groups (P < 0. 01 ). (3) The values of systolic and diastolic pressure of patients with monoallelic expression of H19 were (171 ±9) mm Hg (1 nun Hg =0.133 kPa) and ( 104±8) mm Hg, the values of systolic and diastolic pressure with biallelic expression were ( 194±21 ) mm Hg and ( 124±18) mm Hg. There were significant difference between two groups (P<0.05 ). Conclusion LOI of H19 can be identified in pre-eclamptic placentas and is associated with maternal blood pressures, which implies the involvement of H19 gene LOI in the pathogenesis of pre-eclampsia and its potential relationship with the severity of the disease.
