Objective By observing the echocardiographic dimensions in the acute phase and the intercritical phase of gout, we planned to investigate the effect of acute gouty arthritis on cardiac function. Methods Patients with gout were enrolled from Jun 2019 to Apr 2021 in Department of Rheumatology, Zhongshan Hospital of Fudan University. They were classified into acute gout group and intercritical gout group according to different phases. Clinical data were collected and echocardiographic examination was completed within 1-3 days. Echocardiography was repeated in patients with acute attack 30 days later. Echocardiographic parameters of different groups or different phases in the same group were analyzed and compared. Results Finally, 69 male cases were enrolled. Among them, 32 were acute gout group and 37 were intercritical gout group. Compared with the intercritical gout group, the ejection fraction in the acute gout group decreased ［60% (56%-64%) vs. 64% (62%-65%), Z=-2.814, P=0.005], and the left atrial area reduced [ (13±4) cm² vs. (16±3) cm², t=-4.146, P <0.001]. When serum uric acid was more than 480 µmol/L, the ejection fraction of acute gout group was lower than that of intercritical gout group [59% (55%-62%) vs. 64% (59%-70%), Z=-4.112, P<0.001], and the left atrial area was smaller [ (13±5) cm² /L vs. (17±3) cm² /L, t=-3.121, P=0.003). The echocardiographic parameters were similar among the two groups when serum uric acid was ≤480 μmol/L. The ejection fraction of patients with acute gout in remission stage was better than that in acute attack stage, but the difference was not statistically significant (P=0.78). Conclusion Acute gouty arthritis can decrease ejection fraction in male patients, particularly in patients with high uric acid level. Controlling gout attacks may help reduce the risk of cardiac dysfunction. [ABSTRACT FROM AUTHOR]

Based on time-dependent reliability analyses and the load and resistance factor design approach, a design method of expected service life was developed for reinforced concrete (RC) beams under marine atmospheric environment. First, the initial corrosion time of reinforcing bars was determined based on the Chloride ion transport model in concrete; and then, considering the influence of the variability of corrosion on both distribution of cross-sectional area and mechanical properties of rebars, time-dependent reliability indexes of corroded RC beams were calculated during their expected service lives. Besides, the initial target reliability indexes were redefined in order to ensure the reliabilities of RC beams during their entire expected service lives could meet the requirements of the relevant design specifications. Moreover, based on probability and limit states equations, the adjusted value of reliability index, and the load and resistance partial factors were determined for RC beams with different requirements for expected service live. Finally, the validity of the proposed approach was illustrated using several design cases. [ABSTRACT FROM AUTHOR]

The limit state function for corroded reinforced concrete beams was established, in which the non-uniformity coefficient of corrosion was introduced to consider the non-uniformity of corrosion and randomness of steel bars. Then, according to the principle of conservation of probability, the generalized probability density evolution equation of the limit state function for corroded reinforced concrete beams was derived. Meanwhile,the finite difference method of TVD (total variation diminishing) difference scheme was recommended. Next, the time-dependent reliability calculation method based on the probability density evolution theory was proposed for corroded reinforced concrete beams through ‘absorption boundary conditions’. Further, the generalized probability density evolution equation and the calculation results of time-varying reliability were shown by taking three corroded reinforced concrete beams as examples. Moreover, the accuracies of the probability density evolution and the time-dependent reliability calculation were investigated through one million-scale of Monte Carlo simulation and the two-norm error index. The comparison results of the second-order moment information and the reliability show that the probability density evolution method can accurately capture the probability density evolution information of corroded reinforced concrete beams during its service period with a relative low calculation cost, and then accurately predict the time-varying reliability.
