目的:在建立大鼠牙周炎及大鼠怀孕模型基础上,研究牙周炎与生长受限胎鼠之间的相关关系。方法:11只雌性SD大鼠双侧下颌第一磨牙丝线结扎制作牙周炎动物模型,7只雌性SD大鼠作对照组,2周后将雌鼠与雄鼠合笼建立大鼠怀孕模型。分娩前处死孕鼠,收集孕鼠心脏血、胎鼠,测量胎鼠体重、顶臀长度,ELISA方法检测孕鼠血清中肿瘤坏死因子-α(TNF-α)的浓度。结果:牙周炎组中胎鼠生长受限的发生率为8.3%,显著高于对照组胎鼠生长受限的发生率。牙周炎组生长受限胎鼠的孕鼠TNF-α血清浓度显著高于对照组孕鼠血清浓度(P﹤0.05)。结论:牙周炎是胎鼠生长受限发生的危险因素,可能与牙周局部感染引起血液中TNF-a等炎性细胞因子的改变有关。

Deoxys-BC is the internal tweakable block cipher of Deoxys, a third-round authenticated encryption candidate at the CAESAR competition. In this study, by adequately studying the tweakey schedule,we seek a six-round related-tweakey impossible distinguisher of Deoxys-BC-256, which is transformed from a3.5-round single-key impossible distinguisher of AES, by application of the mixed integer linear programming(MILP) method. We present a detailed description of this interesting transformation method and the MILPmodeling process. Based on this distinguisher, we mount a key-recovery attack on 10(out of 14) rounds of Deoxys-BC-256. Compared to previous results that are valid only when the key size > 204 and the tweak size < 52, our method can attack 10-round Deoxys-BC-256 as long as the key size 174 and the tweak size 82. For the popular setting in which the key size is 192 bits, we can attack one round more than previous studies. Note that this paper only gives a more accurate security evaluation and does not threaten the security of full-round Deoxys-BC-256.

Simpira v2 is a family of cryptographic permutations proposed at ASIACRYPT 2016, and can be used to construct high throughput block ciphers by using the Even-Mansour construction, permutationbased hashing, and wide-block authenticated encryption. This paper shows a 9-round impossible differential of Simpira-4. To the best of our knowledge, this is the first 9-round impossible differential. To determine some efficient key recovery attacks on its block cipher mode（Even-Mansour construction with Simpira-4）,we use some 6/7-round shrunken impossible differentials. Based on eight 6-round impossible differentials, we propose a series of 7-round key recovery attacks on the block cipher mode; each 6-round impossible differential helps recover 32 bits of the master key（512 bits）, and in total, half of the master key bits are *** attacks require 257 chosen plaintexts and 2577-round encryptions. Furthermore, based on ten 7-round impossible differentials, we add one round on the top or at the bottom to mount ten 8-round key recovery attacks on the block cipher mode. This helps recover the full key space（512 bits） with a data complexity of 2;chosen plaintexts and time complexity of 21708-round encryptions. Those are the first attacks on the round-reduced Simpira v2 and do not threaten the Even-Mansour mode with the full 15-round Simpira-4.

The aim of the paper is to estimate the density functions or distribution functions measured by Wasserstein metric, a typical kind of statistical distances, which is usually required in the statistical learning. Based on the classical Bernstein approximation, a scheme is presented. To get the error estimates of the scheme, the problem turns to estimating the L1 norm of the Bernstein approximation for monotone C-1 functions, which was rarely discussed in the classical approximation theory. Finally, we get a probability estimate by the statistical distance.
