ABSTRACT
Objective@#To identify confounding factors associated with dental caries prevention, as the basis for the development of subsequent health management plan for dental caries prevention in young children.@*Methods@#From June to September 2019, a questionnaire survey was conducted among parents of young children enrolled in five kindergartens in the district of Shanggang Steel Community, Pudong New District, Shanghai, using the convenience sampling method. The survey included basic demographic characteristics on parents and children, as well as information factor, motivation factor, behavioral skills, and caries prevention behavior.@*Results@#Among 718 parents surveyed, the median information factor score was 8 (7, 9), the median personal motivation factor score was 20 (19, 20), the median social motivation factor score was 9 (8, 10), the median behavioral skills score was 25 (24, 25), and the median caries prevention behavior score was 7 (5, 8). Motivation factor was positively associated with behavioral skills, both information factor and behavioral skills were positively associated with dental caries prevention (P<0.05). Personal motivation factor had a direct influence factor of 0.80 on behavioral skills and an indirect influence factor of 0.15 on dental caries prevention behavior; behavioral skills and information factor had a direct influence factor of 0.19 and 0.26 respectively on dental caries prevention.@*Conclusion@#The finding suggest that in addition to oral hygiene information and education for parents of young children, mental support should be a key component of any community-based dental caries prevention program.
ABSTRACT
Objective To explore risk factors of the progression to castration-resistant prostate cancer(CRPC)after hormone therapy (HT).Methods A total of 178 patients with prostate cancer from February 2009 to February 2018 were enrolled to analyze the risk factors of the progression to castrationresistant prostate cancer after androgen deprivation therapy in Fujian Medical University Union Hospital.The mean age was72 years (range,49-91 years);the middle Gleason score was 7 (range,4-10);the middle PSA at the initiation of HT was 24.45 ng/ml (range,0.16-100.0 ng/ml);the middle time to PSA nadir was 9 months (range,0.5-69.0 months);the middle PSA nadir after HT was 0.030 ng/ml (range,0.003-78.670 ng/ml);the mean hemoglobin level was 131 g/L (range,64-184 g/L);the mean alkaline phosphatase level was 98 U/L (range,35-734 U/L);39 patients were diabetes mellitus (21.9％);82 patients were bone metastasis/visceral metastasis (46.1％);85 patients (47.8 ％) were in clinical T1 + T2;93 patients(52.2％)were in clinical T3 + T4.We studied the relationship between CRPC and these risk factors including age,Gleason score,PSA at the initiation of HT,PSA nadir after HT,the time to PSA nadir,hemoglobin level,alkaline phosphatase,bone metastasis/visceral metastasis,clinical T stage,diabetes mellitus by x2 test,univariate and multivariate Cox regression analysis methods.Results The middle follow-up time was 30 months (range,6-92 months).There were 74 of 178 patients progressed to CRPC after HT.The median time of progression to CRPC in this cohort was 15 months (range,4-47 months).On x2 test analysis,there were statistically significant differences between the progression to CRPC group after HT and the rest group in Gleason score (P ＜0.001),PSA nadir after HT (P ＜0.001),PSA at the initiation of HT (P =0.042),alkaline phosphatase (P =0.002),bone metastasis/visceral metastasis (P＜0.001) and clinical T stage (P ＜0.001).Additionally,on multivariate Cox regression analysis,Gleason score (OR =6.152,P ＜ 0.001),PSA nadir after HT (OR =3.022,P ＜ 0.004) and the time to PSA nadir (OR =0.375,P ＜0.001) were found to be significantly associated with the rapid progression to CRPC.Conelusions Gleason score,PSA nadir after HT and the time to PSA nadir were significantly associated with the progression to CRPC.Patients with higher PSA nadir or the shorter time to PSA nadir were more likely to progress to CRPC.
ABSTRACT
Objective To identify the risk factors for prostate-sparing cystectomy by evaluating the risk of prostatic invasion or incidental prostatic adenocarcinoma (PCa) in bladder cancer (BCa) patients undergoing radical cystectomy.Methods The patients undergoing radical cystectomy from 2009 to 2014 in Fujian Medical University Union Hospital were enrolled to analyze the risk factors of prostatic tumor invasion.These factors included age,tumor size,location,quantity,histologic grade and pathologic stage.Results In the 123 male patients,the mean age was 60 years (range,31-78 years);23 (18.7％) patients had BCa or PCa in the prostate;14 (11.4％) had prostatic Bca;11 (8.9％) had PCa.The risk factors of prostatic BCa included multifocal bladder tumors (OR =26.70,P =0.032),tumor in the bladder neck and trigone(OR =17.13,P =0.013),pathological stage (OR =26.70,P ＜ 0.001).Among the 11 patients with PCa,3(27.3％) patients had Gleason score of ≥7,8(72.7％) patients ≤6 and 2(18.2％) patients had extracapsular extension.Three patients had clinically significant PCa.The factor of advanced age was associated with incidental PCa (P =0.003).Conclusion The risk factors of prostatic tumor invasion in patients undergoing radical cystectomy included advanced age,bladder tumor in bladder neck and trigone,muhifocal bladder tumors,and advanced pathological stage.
ABSTRACT
BACKGROUND: AG490 is a newly found JAK kinase inhibitor, which can compete with receptor tyrosine kinase for binding site to block JAK/STAT pathway, inhibit rejection-related cytokine activation such as interferon-gamma (IFN-γ) ultimately inhibiting rejection.OBJECTIVE: To evaluate the possibility and prospect of the AG490 as a potential immunosuppressor, explore its basic mechanism in comparison with Cyclosporine A (CsA).DESIGN, TIME AND SETTING: Comparative observation was performed at the Institute of Urinary Surgery, Fujian Union Hospital from October 2007 to April 2008.MATERIALS: AG490 was purchased from Sigma, USA.METHODS: Human peripheral blood lymphocyte (both T and B) were harvested from 8 healthy donors. Lymphocyte were isolated by density gradient method and cultured with phytohemagglutinin, interleukin-2 (IL-2) or mixed lymphocyte culture to induce human lymphocyte proliferation. MAIN OUTCOME MEASURES: ELISA was used to detect the concentration of IL-2, IFN-γ and IL-6 in different culture systems with the tyrphostin (AG490), CsA or FK506. RESULTS: IL-2 and IFN-γ in culture systems of phytohemagglutinin, IL-2 or mixed lymphocyte culture were inhibited by AG490 (P < 0.05), but IL-6 was not suppressed by AG490 (P < 0.05). This effect was similar to clinical CsA or FK506. CONCLUSION: AG490 may be a potential immunosuppressor.
