RESUMO
Objective@#To investigate the prevalence of diabetes among individuals at high risk of diabetes in Baoshan District, Shanghai Municipality, so as to provide insights into community-based diabetes management. @*Methods@#Permanent residents at ages of 35 years and older were sampled from Baoshan District using a multistage stratified cluster sampling method, and residents at a high risk of diabetes were screened using the Form for Risk Assessment of Diabetes among Community Residents in Shanghai Municipality. Participants' demographics, disease history and history of medication were collected using questionnaire surveys, and height, body weight, waist circumference, hip circumference, and blood pressure were measured. Diabetes was screened using fasting blood glucose and glucose tolerance test. The factors affecting the development of diabetes were identified among high-risk residents for diabetes using a multivariable logistic regression model.@*Results@#A total of 3 107 residents at a high risk for diabetes were enrolled, including 1 165 men (37.50%) and 1 942 women (62.50%) with a mean age of (63.58±9.77) years. The prevalence of diabetes was 21.69% among the study subjects, and multivariable logistic regression analysis showed that men (OR=1.689, 95%CI: 1.357-2.104), age (40 years-, OR=4.833, 95%CI: 1.036-22.553; 50 years-, OR=2.627, 95%CI: 1.432-4.819; 60 years-, OR=1.551, 95%CI: 1.119-2.150; 70 years and older, OR=1.579, 95%CI: 1.232-2.025); high school/technical secondary school (OR=2.677, 95%CI: 1.636-4.380), overweight/obesity (OR=1.891, 95%CI: 1.447-2.472), hypertension (OR=1.306, 95%CI: 1.049-1.626), dyslipidemia (OR=1.428, 95%CI: 1.114-1.831), history of impaired glucose regulation (OR=15.161, 95%CI: 11.827-19.434) and family history of type 2 diabetes mellitus (OR=2.092, 95%CI: 1.619-2.704) caused an increased risk of diabetes among residents at a high risk diabetes.@*Conclusions@#The prevalence of diabetes was 21.69% among high-risk populations of diabetes in Baoshan District. Gender, age, educational level, overweight/obesity, hypertension, dyslipidemia, history of impaired glucose regulation and family history of type 2 diabetes mellitus are factors affecting the development of diabetes among high-risk populations.
RESUMO
@#Objective: To analyze the correlation between WT1 gene polymorphism and multiple myeloma (MM) susceptibility in 168 patients. Methods: One hundred and sixty eight MM patients, who were hospitalized in our hospital and Hebei Provincial People's Hospital from January 2013 to December 2017, were researched in this study. There were 121 males (72%) and 47 females(28%) with a median age of 62.4 years old (36~83 years old). Polymorphism of WT1 gene of the samples was detected and analyzed by SSP-PCR and SBT-PCR. Results: Eleven WT1 alleles were detected in MM patients, WT1*010 and WT1*012 alleles occupied a higher frequency in MM group (WT1*010: OR=6.13, 95%CI:3.5~10.75, PC<0.000; WT1*012: OR=2.06, 95%CI:1.23~1.44, PC<0.051). STR genotype frequency of WT1*A5 markedly increased (OR=1.62, 95%CI:1.18~2.23, PC<0.05). Genotype frequency of WT1*010/010 also obviously increased (OR=6.28, 95%CI:1.81～21.76, PC<0.05). Conclusion: WT1 allele is highly polymorphic in MM patients and homozygote WT1*010/010 is a susceptible genotype of MM, indicating that the occurrence and development of MM are related to the polymorphism of WT1 gene.
RESUMO
Background: Rocuronium is an alternative to succinylcholine for rapid tracheal intubation after major thermal injury and other forms of critical illness that cause denervation changes in skeletal muscle. Rocuronium may decrease the potencies of non-depolarizing muscle relaxants. Objectives: Examine whether potency of rocuronium changed during the first month after denervation, and investigate the effects of skeletal muscle denervation on potency of rocuronium. Methods: The denervation mouse model was developed to create denervated individual cells from the flexor digitorum brevis of the hindfoot. The skeletal muscle cells were examined at day 0 in the innervated control and days 1, 4, 7, 14, 21, and 28 in the denervation group. Nicotinic acetylcholine receptors in the cells were activated with 30 M acetylcholine, alone or in combination with various concentrations of rocuronium. Currents were recorded with a whole-cell patch-clamp technique. Results: Rocuronium reversibly inhibited acetylcholine-activated currents in a dose-dependent fashion at different times after denervation. The inhibition concentration for the half-maximal responses of rocuronium increased 1.2- (p >0.05), 1.8-, 2.8-, 2.3-, 2.1-, and 1.9-fold (p<0.01) at day 1, 4, 7, 14, 21, and 28 after denervation, respectively, compared to that at day 0 after denervation. Conclusion: Rocuronium dose required to achieve satisfactory clinical effects changed at different durations after skeletal muscle denervation.
