RESUMO
Objective To investigate the changes in dietary behavior and physical exercise of people of different ages during the epidemic of Coronavirus Disease 2019 (COVID-19), and to explore the influencing factors of weight gain. Methods A structured electronic questionnaire was used to investigate the basic conditions, weight, eating behavior and physical exercise of 1 125 subjects. The χ2 test or non-parametric test was used to compare the changes in the three age groups (65 years), and Logistic regression analysis was used to explore the factors affecting weight gain. Results Among the three age groups, young people under 30 years old changed greatly in the consumption of grains, red meat, and high-calorie snacks, and in the physical exercise, and there was a significant amount of people experiencing such changes, while for those older than 65 years old, the frequency of intake of grains, red meat, and high-calorie snacks before and after the outbreak was basically unchanged. In addition, compared with the population who basically did not change dietary behavior during the epidemic, the increase in the consumption of grains (OR = 2.469), red meat (OR = 1.582), and high-calorie snacks (OR = 1.815), and the decrease in physical exercise (OR = 1.702 ) were independent risk factors for weight gain during the epidemic (P 65 years old) maintained basically unchanged. The increased intake of grains, red meat and high-calorie snacks, and lack of physical exercise could lead to weight gain.
RESUMO
Objective:Calcium/calmodulin-dependent kinase kinase (CAMKK2) is activated in prostate cancer (PCa). The aim of our study is to identify the effects of preadipocyte and CAMKK2 on the PCa cell invasion.Methods:The coculture system between PCa cells and preadipocyte cells (3T3L1) was established and then Transwell assay was used to determine the invasive effect after coculture. Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to investigate the CAMKK2 expression in the coculture system.Results:The 3T3L1 cells promoted the invasion of PCa cells (DU145 and 22RV1; P<0.01). Meanwhile, the 3T3L1 cells can increased expression of CAMKK2 in PCa cells ( P<0.01). CAMKK2 reversed the invasive effects of preadipocyte cells on the PCa cells. Conclusions:Our study demonstrates that the preadipocyte may promote the PCa cell invasion possibly by mediating the CAMKK2 expression.
RESUMO
Objective To compare the safety and efficacy of minimally-access percutaneous nephrolithotomy (Mini-PCNL) in modified lateral position and prone position in high-risk patients with upper urinary tract stones and explore the clinical value of the modified lateral position. Methods We retrospectively analyzed 82 cases of high-risk patients underwent ultrasound-guided percutaneous nephrolithotomy from June 2010 to December 2015. 43 cases in group of modified lateral position and 39 case in group of prone position. The mean operating time, the success rate of stone fragmentation, hospitalization days, the value of postoperative hemoglobin decline and complication rate of patients were record and compared between the two groups. Results There was no statistical significance between the modified lateral position group and prone position group (P > 0.05) in gender, age, stone type, BMI, the score of ASA and preoperative complication. There was statistical significance in found access time, (7.88 ± 0.82) min in the modified lateral position group and (8.50 ± 0.80) min in the prone position group (P 0.05). Conclusions The Mini-PCNL in modified lateral position for high-risk patients had advantages of found access time, stone clearance rate, pleural injury, blood loss, comfort degree and security and worthy of clinical promoting.
