There have been reports of potential health risks for people from hydrophobic organic pollutants,such as polycyclic aromatic hydrocarbons(PAHs),polychlorinated hydrocarbons(PCHs),and organophosphate flame retardants(OPFRs).When a contaminated site is used for residential housing or public utility and recreation areas,the soil-bound organic pollutantsmight pose a threat to human *** this study,we investigated the contamination profiles and potential risks to human health of 15 PAHs,6 PCHs,and 12 OPFRs in soils from four contaminated sites in *** used an in vitro method to determine the oral bioaccessibility of soil *** PAHswere found at concentrations ranging from26.4 ng/g to 987 ng/***(0.27-14.3 ng/g)and OPFRs(6.30-310 ng/g)were detected,but at low levels compared to earlier *** levels of PAHs,PCHs,and OPFRs released from contaminated soils into simulated gastrointestinal fluids ranged from 1.74%to 91.0%,2.51%to 39.6%,and 1.37%to 96.9%,*** on both spiked and unspiked samples,we found that the oral bioaccessibility of pollutantswas correlated with their logKow andmolecularweight,and the total organic carbon content and pH of *** in 13 out of 38 contaminated soil samples posed potential high risks to *** considering oral bioaccessibility,nine soils still posed potential risks,while the risks in the remaining soils became *** contribution of this paper is that it corrects the health risk of soil-bound organic pollutants by detecting bioaccessibility in actual soils from different contaminated sites.

Objective: To examine the effectiveness of Chinese medicine(CM) Lianhua Qingwen Granule(LHQW) and Jingyin Gubiao Prescription(JYGB) in asymptomatic or mild patients with Omicron infection in the shelter hospital. Methods: This single-center retrospective cohort study was conducted in the largest shelter hospital in Shanghai, China, from April 10, 2022 to May 30, 2022. A total of 56,244 asymptomatic and mild Omicron cases were included and divided into 4 groups, i.e., non-administration group(23,702 cases), LHQW group(11,576 cases), JYGB group(12,112 cases), and dual combination of LHQW and JYGB group(8,854 cases). The length of stay(LOS) in the hospital was used to assess the effectiveness of LHQW and JYGB treatment on Omicron infection. Results: Patients aged 41–60 years, with nadir cycle threshold(CT) value of N gene <25, or those fully vaccinated preferred to receive CM therapy. Before or after propensity score matching(PSM), the multiple linear regression showed that LHQW and JYGB treatment were independent influence factors of LOS(both P<0.001). After PSM, there were significant differences in LOS between the LHQW/JYGB combination and the other groups(P<0.01). The results of factorial design ANOVA proved that the LHQW/JYGB combination therapy synergistically shortened LOS(P=0.032). Conclusions: Patients with a nadir CT value <25were more likely to accept CM. The LHQW/JYGB combination therapy could shorten the LOS of Omicron-infected individuals in an isolated environment.

在推进新兴区域一体化发展的过程中,依赖财税法传统的纵向财政转移支付或自上而下给予特定区域税收优惠的方式已难以满足需要。与此不同,区域财税合作采取跨行政区划的、以地方政府间横向财税利益协调为核心内容的新机制,成为财税法促进区域一体化发展的新的着力点。在现有规范体系下,区域财税合作具备实施依据,并形成了区域财政补偿合作、财政投入合作、税收征管合作、税收分享合作等典型样态。但整体上,区域财税合作仍处于政策指引阶段,法治化发展水平明显不足,面临在财税合作的收支方式上如何处理与财税法定原则之间的关系,在财税合作的纵横级次上如何应对区域共同财政事权与支出责任配置的缺位,在财税合作的规范形式上如何实现财税合作软法规范的效力补强与内容约束等问题,亟待做出回应,推动区域财税合作的法治化发展。

To the Editor:We read with great interest the recent article by Balci et al.[1].In the study, the authors mentioned that their mixed reality (MR)technology has already successfully been applied in open and laparoscopic living donor hepatectomy and in complex laparoscopic liver resections. During such operations, the MR models of the liver are pulled out and superimposed onto the actual organ. Surgeons canverifytherelationshipbetweentumorsandcrucialareasin ordertoenhancemarginclearanceandR0resectionandreduce the risk of injuring major blood vessels. By applying MR (including augmented reality) technology, blood vessels and tumor structures in the liver can be displayed during surgery, which permits precise navigation during complex surgical procedures. Also MR was used in surgical education, and most learners believed that 3D models were useful in planning safer surgical paths, reducing intraoperative complications and training of young surgeons [2].

新加坡的语言政策与国家身份建构息息相关,因而一直受到学界的关注。然而,国家安全是新加坡国家身份建构的前提。因此,本文从国家安全的视角出发,分析了语言政策在新加坡的国际政治安全、国内社会安全、经济安全和文化安全等方面所起的作用,指出新加坡的双语制制造了新加坡语言身份与文化身份的割裂,在一定程度上阻碍了新加坡文化安全的实现,可能最终威胁到新加坡的国家安全。
