目的分析内蒙古自治区砷中毒地区居民的主要死因,为砷中毒防治远期效应和保障居民健康提供科学依据。方法收集2016-2021年内蒙古自治区砷中毒地区居民死因资料(来自人口死亡信息登记管理系统和内蒙古自治区各盟市统计局人口信息系统),并根据是否饮用过高砷水将居民分为暴露组和非暴露组。采用SPSS 25.0软件统计分析粗死亡率(CDR)、标准化死亡率(SMR)、疾病别死亡率、死因构成比、死因顺位等。结果6年累计死亡病例9583人,年均CDR为633.12/10万,年均SMR为446.65/10万。各年份CDR随时间呈下降趋势(χ^(2)=1058.86,P<0.001)。男性CDR高于女性(χ^(2)=325.04,P<0.001)。砷中毒地区居民疾病死因以心脏病和恶性肿瘤为主,构成比分别为25.00%(2396/9583)、18.86%(1807/9583);恶性肿瘤死亡前3位依次是肺癌、肝癌、胃癌。暴露组主要疾病死因和恶性肿瘤死因的SMR均高于非暴露组(χ^(2)=147.08、26.26,均P<0.001)。结论内蒙古自治区砷中毒地区居民主要疾病死因为心脏病和恶性肿瘤,其中恶性肿瘤死亡前3位依次是肺癌、肝癌、胃癌。尽管目前全区砷中毒地区已基本实现改水,但慢性砷暴露的远期效应依然存在。

For the linear discrete time-invariant stochastic system with correlated noises, and with unknown model parameters and noise statistics, substituting the online consistent estimators of the model parameters and noise statistics into the optimal time-varying Riccati equation, a self-tuning Riccati equation is presented. By the dynamic variance error system analysis （DVESA） method, it is rigorously proved that the self-tuning Riccati equation converges to the optimal time-varying Riccati equation. Based on this, by the dynamic error system analysis （DESA） method, it is proved that the corresponding self-tuning Kalman filter converges to the optimal time-varying Kalman filter in a realization, so that it has asymptotic optimality. As an application to adaptive signal processing, a self-tuning Kalman signal filter with the self-tuning Riccati equation is presented. A simulation example shows the effectiveness.

The white noise deconvolution or input white noise estimation problem has important applications in oil seismic exploration, communication and signal processing. By the modern time series analysis method, based on the autoregressive moving average （ARMA） innovation model, a new information fusion white noise deconvolution estimator is presented for the general multisensor systems with different local dynamic models and correlated noises. It can handle the input white noise fused filtering, prediction and smoothing problems, and it is applicable to systems with colored measurement noises. It is locally optimal, and is globally suboptimal. The accuracy of the fuser is higher than that of each local white noise estimator. In order to compute the optimal weights, the formula computing the local estimation error cross-covariances is given. A Monte Carlo simulation example for the system with Bernoulli-Gaussian input white noise shows the effectiveness and performances.
