Soil moisture plays an important role in land-atmosphere interactions. It is an important geophysical parameter in research on climate, hydrology, agriculture, and forestry. Soil moisture has important climatic effects by influencing ground evapotranspi ration, runoff, surface reflectivity, surface emissivity, surface sensible heat and latent heat flux. At the global scale, the extent of its influence on the atmosphere is second only to that of sea surface temperature. At the terrestrial scale, its influence is even greater than that of sea surface temperatures. This paper presents a China Land Soil Moisture Data Assimilation System (CLSMDAS) based on EnKF and land process models, and results of the application of this system in the China Land Soil Moisture Data Assimilation tests. CLSMDAS is comprised of the following components: 1) A land process mo del—Community Land Model Version 3.0 (CLM3.0)—developed by the US National Center for Atmospheric Research (NCAR); 2) Precipitation of atmospheric forcing data and surface-incident solar radiation data come from hourly outputs of the FY2 geostationary meteorological satellite; 3) EnKF (Ensemble Kalman Filter) land data assimilation method; and 4) Observa tion data including satellite-inverted soil moisture outputs of the AMSR-E satellite and soil moisture observation data. Results of soil moisture assimilation tests from June to September 2006 were analyzed with CLSMDAS. Both simulation and assimila tion results of the land model reflected reasonably the temporal-spatial distribution of soil moisture. The assimilated soil mois ture distribution matches very well with severe summer droughts in Chongqing and Sichuan Province in August 2006, the worst since the foundation of the People’s Republic of China in 1949. It also matches drought regions that occurred in eastern Hubei and southern Guangxi in September.

Subsurface runoff in a land surface model is usually parameterized as a single-valued function of total storage in a basin aquifer reservoir. This kind of parameterization is often sin-gle-valued function of storage-discharge under a steady or “quasi-steady” state, which cannot rep-resent the influence of aquifer recharge on subsurface runoff generation. In this paper, a new sub-surface runoff parameterization with water storage and recharge based on the Boussinesq-storage equation is developed. This model is validated by a subsurface flow separation algorithm for an ex-ample river basin, which shows that the new model can simulate the subsurface flow reasonably.

Objective: To explore the therapeutic effect of traditional Chinese medicine Jianpi Qushi powder combined with standard anti-HP quadruple therapy in the treatment of HP infectious gastritis with spleen deficiency and dampness stagnation. Methods: From January 2020 to December 2021, 223 patients with laboratory-confirmed HP infection who were admitted to the Outpatient and Inpatient Department of Internal Medicine in our hospital were selected as the research objects and randomly divided into two groups. 101 patients in the control group were given standard anti HP quadruple therapy;122 cases in the treatment group were given traditional Chinese medicine Jianpi Qushi powder combined with standard anti HP quadruple therapy. The two groups were rechecked carbon breath test after the designed course of treatment, and the curative effects of the two groups were compared. Results: 113 cases in the treatment group were cured by traditional Chinese medicine Jianpi Qushi powder combined with standard anti HP quadruple therapy, and the cure rate was 92.62%. 84 cases in the control group were cured by standard anti HP quadruple therapy, and the cure rate was 83.17%, χ2 = 4.7955, P = 0.0285, the difference was statistically significant (P < 0.05). Conclusion: Traditional Chinese medicine Jianpi Qushi powder combined with standard anti HP quadruple therapy in the treatment of HP infectious gastritis with spleen deficiency and dampness stagnation is one of the best treatment schemes for HP infection. The results of this study achieve the best clinical treatment effect, and provide a more valuable and reliable method for the treatment of gastropathy in clinical internal medicine, which is worthy of popularization and application.

Objective: To understand the clinical value of combined detection of cholyglycine CG and TBA in differential diagnosis of hepatobiliary diseases. Methods: Serum samples from 50 healthy people were collected as healthy control group. According to the latest disease diagnosis and treatment plan, 58 cases of HBV asymptomatic carrier group, 17 cases of viral hepatitis group, 49 cases of cirrhosis group, 50 cases of primary liver cancer group and 50 cases of other hepatobiliary diseases groups were collected respectively. The concentration levels of cholyglycine and total bile acid in each group were detected, and the differences among each group were compared. Results: By statistical analysis, serum CG concentration in viral hepatitis group, cirrhosis group, primary liver cancer group and other hepatobiliary diseases group was significantly higher than that in asymptomatic HEPATITIS B carriers and healthy control group, the differences were statistically significant (p 0.05). There was no significant difference in CG concentration among viral hepatitis group, liver cirrhosis group, primary liver cancer group and other hepatobiliary diseases group (p > 0.05). The serum TBA levels of asymptomatic carriers, viral hepatitis group, cirrhosis group, primary liver cancer group and other hepatobiliary system diseases group were significantly higher than those of healthy control group, the difference was statistically significant, p 0.05. Conclusion: Serum CG expression can not only detect liver lesions, but also distinguish different liver lesions. The positive rate of CG combined with TBA detection in patients with hepatobiliary diseases is significantly higher than that of single CG index detection. CG combined with TBA detection can significantly improve the sensitivity and accuracy of the diagnosis of hepatobiliary diseases, which is worthy of popularization and application.

近年来以快速暴发为主要特征的骤发干旱(骤旱)在全球范围内频繁发生,给社会经济和生态环境造成了严重影响。通过回顾骤旱形成与演变机制的研究进展,发现骤旱形成的主要原因是高强度降水亏缺,而蒸散发增加使得干旱暴发加速,进而触发骤旱。这些气象要素异常与海温异常模态(如厄尔尼诺—南方涛动、北大西洋三极子、印度洋偶极子等)及其相关的大气环流异常密切相关,同时局地和非局地陆面异常在骤旱暴发与维持过程中的作用也不容忽视。加之气候和下垫面变化协同影响海—陆—气耦合过程,使得骤旱发生发展过程更为复杂,演变趋势存在较大不确定性。因此,未来研究亟须在骤旱暴发与维持的大尺度环流背景以及关键陆面和海洋信号的影响、骤旱—植被相互作用、骤旱演变对环境变化的响应机制等方面取得突破。

目的探讨染色体核型分析结合单核苷酸多态性微阵列芯片(single nucleotide polymorphism array,SNP-Array)检测在妊娠早期胎儿颈项透明层(nuchal translucency,NT)增厚中的临床应用价值。方法选取2017年5月至2022年6月于金华市妇幼保健院因产前超声提示NT增厚而就诊的223例孕妇为研究对象,经羊水穿刺抽取样本进行染色体核型分析和SNP-Array检测,对结果进行整理与分析。结果胎儿染色体核型分析异常42例(18.8%),其中非整倍体数目异常32例(76.2%),结构异常7例(16.7%),嵌合体3例(7.1%);6例异常染色体核型分析结果与SNP-Array检测结果不符。SNP-Array检测结果异常50例(22.4%),36例检测结果与染色体核型分析结果一致,额外发现14例染色体有微缺失或微重复。随着NT值增大,染色体异常检出率上升,但不同NT值间的异常检出率比较差异无统计学意义(P>0.05)。NT增厚结合其他异常指标的染色体异常检出率显著高于单一NT增厚(P<0.01)。结论NT增厚与胎儿异常染色体关系密切,染色体核型分析联合SNP-Array检测对异常染色体进行检测能够提高异常检出率,做到早发现、早干预,为临床遗传咨询提供帮助。

Science China Materials 2025年第1期 309-311页

作者： Tian liang Xiaoming Zhu Hubei Key Laboratory of Radiation Chemistry and Functional Materials School of Nuclear Technology and Chemistry & Biology Hubei University of Science and Technology

To date, there has been no report on fast-charging and Ahlevel sodium-ion batteries (SIBs) by utilizing thick hard carbon anodes that demonstrate prolonged cycling life and high areal capacity at high rates. Further, the relationship among the complex structure of hard carbon, storage mechanism, and fastcharging performance in alkali-metal ion batteries has been a subject of ongoing debate [1,2].
