呼吸道合胞病毒(Respiratory syncytial virus,RSV)是导致美国婴儿住院的主要原因。尼塞韦单抗已被推荐用于预防婴儿RSV相关下呼吸道感染(Lower respiratory tract infection,LRTI)。2023年8月,美国食品药品监督管理局(Food and Drug Administration,FDA)批准将单剂量RSVpreF疫苗用于妊娠32-36周孕妇,以预防<6月龄婴儿发生RSV相关LRTI。自2021年10月起,美国免疫实践咨询委员会(Advisory Committee on Immunization Practices,ACIP)RSV疫苗母婴工作组审查了RSV流行病学和RSV母婴预防产品(包括RSVpreF疫苗)在安全性、保护效果和潜在经济影响方面的证据。2023年9月22日,ACIP和疾病控制与预防中心(Centers for Disease Control and Prevention,CDC)推荐采用季节性接种方式(在美国大陆大部分地区为9月至次年1月)为妊娠32-36周孕妇接种RSVpreF疫苗,以预防<6月龄婴儿发生RSV相关LRTI。孕妇在妊娠期间接种RSVpreF疫苗或者为婴儿使用尼塞韦单抗都是预防婴儿发生RSV相关LRTI的推荐方法,但大多数婴儿不需要同时采用两种方法。所有婴儿应通过上述某种产品获得保护,以预防RSV相关LRTI。

There are various well described forms of chronic cholestatic jaundice in adults, such as autoimmune cholangitis, drug-induced cholangitis and intrahepatic cholestasis of pregnancy. We present two cases of prolonged cholestasis following removal of gallstones at endoscopic retrograde cholangiopancreatography （ERCP） and subsequent clear cholangiography. Both patients were taking oral estrogens at the time of presentation, which were subsequently withdrawn. The first case responded rapidly to corticosteroid treatment, and the second case had a much slower resolution with ursodeoxycholic acid. Both cases highlighted the significance of estrogen-induced cholestasis in female patients with protracted jaundice following ERCP and removal of intra-ductal stones. After oral estrogens are discontinued, a short course of steroids needs to be considered.

The interaction between C-60's in solid C-60 has been calculated by (exp-6-1) potential, and the cause and the controlled factor of the high rapid rotations of C-60's were discussed. In order to describe the disordered degree of C-60 rotation, an equivalent M is introduced. The phase transitions at the similar to 260 K and at the similar to 90 K are studied from the viewpoint of C-60 rotation. The potential barriers of the ordered rotation below the similar to 260 K and the disordered rotation above the similar to 260 K have been given, and the effect of the external pressure on the temperature of phase transition has also been given.

A Monte-Carlo approach of cellular pattern evolution during directional solidification of a binary alloy has been carried out by imposing a non-uniform probability distribution of particle emission from the particle source, as an approach to the contribution of solute redistribution to the interface evolution. Both the bulk and interface diffusion have been involved in the simulation, and coarsening of the cellular patterns with time has been clearly revealed. The remarkable influence of the interface relaxation and the solute redistribution on the profile bf;solidifying interface has been presented.

The liquid steel will be leaked from the slit between the bottom of solidification mold and mother sheet during inversion casting process. By substitution of the actual liquid steel, the Ph-Sn alloy and the numerical simulation can be used to study the fluid flow in the inversion solidification mold, the mother sheet critical speed is determined for preventing the leakage from the slit of bottom. When the mother sheet speed is more than 0.06 m/s, Pb-Sn liquid alloy will not leak from the slit of the mold. Otherwise, the Ph-Sn liquid alloy can leak from the slit of the mold.

Annealing at T-a=200 degrees C or so, the enhancement in the average tensile fracture strength of as-quenched (Fe0.99Mo0.01)(78)Si9B13 metallic glass increases about 7 similar to 8%. The origin of the annealing embrittlement at 244 degrees C in the metallic glass (Fe0.99Mo0.01)(78)Si9B13 was revealed that due to the formation of nanoscale granular with bcc structure resulting in the stress localization. The temperature of annealing embrittlement was in agreement with the calculated value from T-bcc=0.637 T-c (T-c is the crystallized temperature), based on micromechanism of crystallization of metallic glass.

The suitability of calculating atomic multipole moments from AM1 wave functions by cumulative potential-derived method has been investigated. It is shown that this method has a faster convergence of the fitting process and gives a better description of the charge distribution than the original PD method. Atomic charges obtained in this way are of comparable quality with 6-31G* data and the calculated dipole moments are closer to the experimental data than the values computed directly from the AM1 charges. The results demonstrate that the atomic multipole moments higher than monopole moment can be used to supplement the atomic charge to obtain a more accurate description of charge distribution. For the sake of comparison, both the Williams fitting potential surface and the Connolly one are used in the calculation.

The interaction between C60 cage and the centerhalogen atoms in endoheoral complexes(HalogenC60)(Halogen=Hal=F,ClBr1),including electro-static interaction,dispersive interection and repulsive interaction,have been calculated by molecular molecular mechanics method combined with the results obtained by quantum-chemical EHMO/ASED method The computational results show that the total interaction is attraction which reduces the endohedral comples system except for,and the electro-static interaction plays a decisive role in the three forms of interactions,reaching up more than 90%. For the endohedral complex the resultant non-bonded interaction is *** is a similar variation trend for the total energy variation of system and the total interaction energy of which the order is (F@C_(60))<(cl@C(60))<(I@C(60)).
