Objective To systematically evaluate the demand rate of Traditional Chinese Medicine(TCM) nursing technology for older adults in China. Methods The Web of Science, Cochrane Library, PubMed, Embase, CNKI, CQ VIP, WanFang Data and SinoMed were retrieved for researches about the need of TCM nursing technology in older adults and (or) studies on factors influencing the rate of demand. These databases were systematically searched from inception up to March 1, 2023. Two researchers independently screened and used American Agency for Health care Research and Quality scale for quality evaluation. The meta-analysis was conducted using R4. 2. 3 software. Results A total of seven articles finally were included. The random effects models were used to combine the demand rate due to high heterogeneity. The results showed that the demand rate of TCM nursing technology for older adults was 86. 0% ［95% CI (69. 0%, 94. 0%)］. The analysis results of each subgroup showed that the demand rate of TCM nursing technology for older adults was higher among those who published after 2020, adopted random sampling method, had a sample size of less than 281 cases, lied in hospitals, located in the north of the survey area, and lived in cities. Conclusion Older adults have higher demand for TCM nursing technology. Although related studies explored factors influencing the demand rate, the heterogeneity among the studies is relatively large, resulting in controversial conclusions. Therefore, it is necessary to further explore the factors influencing the demand rate of TCM nursing technology for older adults. Future studies should focus on increasing health education and practical application of TCM nursing technology for older adults in a demand-oriented manner. In addition, the advantages of TCM nursing technology should be given full play in the prevention and treatment of chronic diseases in older adults.

We report that alkali ions (sodium or potassium) added in small amounts activate platinum adsorbed on alumina or silica for the Low-temperature water-gas shift (WG5) reaction ([H.sub.2]O + CO [right arrow] [H.sub.2] + C[O.sub.2]) used for producing [H.sub.2]. The alkali ion--associated surface OH groups are activated by CO at low temperatures (~100[degrees]C in the presence of atomically dispersed platinum. Both experimental evidence and density functional theory calculations suggest that a partially oxidized Pt-alkali-[O.sub.x][(OH).sub.y] species is the active site for the low-temperature Pt-catalyzed WGS reaction. These findings are useful for the design of highly active and stable WGS catalysts that contain only trace amounts of a precious metal without the need for a reducible oxide support such as ceria. 10.1126/science.1192449

In this study, the mechanism of ammonium bisulfate (ABS) formation and decomposition over V/WTi for the NH3-selective catalytic reduction (SCR) at various temperatures was deeply investigated. Bridged bidentate, chelating bidentate, and tridentate sulfates bound to TiO2 were formed as dominant intermediates at 200, 250, and 300 °C, respectively. These sulfates reacted with affinitive ammonium species to form ammonium (bi)sulfate species and also covered the active sites and embedded the VOSO4 intermediates, which resulted in an inferior intrinsic NH3-SCR conversion rate at 200 °C and 250 °C. At 300 °C, trace amounts of ABS on TiO2 presented no influence on the NH3-SCR performance. The electrons deviating towards sulfates through the bond between ABS and metal oxides (WO3 and TiO2) weakened the stability of ABS and lowered its decomposition temperature, whereas the vanadia species played the opposite role due to the sulfur species existing in an electron saturation state with the formation of the VOSO4 intermediate. The presence of NO + O2 could break the bonds inside ABS and it could react with the ammonium species originating from ABS, which pulls NH3 out of the ABS formation equilibrium and accelerates its decomposition and competitively inhibits its formation. Correspondingly, the faster NH3-SCR conversion rate and higher N2 selectivity improve the ABS poisoning resistance of the V/WTi catalyst at low temperatures. [ABSTRACT FROM AUTHOR]

We report that alkali ions (sodium or potassium) added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H2O + CO → H2 + CO2) used for producing H2. The alkali ion-associated surface OH groups are activated by CO at low temperatures (∼100°C) in the presence of atomically dispersed platinum. Both experimental evidence and density functional theory calculations suggest that a partially oxidized Pt-alkali-Ox(OH)y species is the active site for the low-temperature Pt-catalyzed WGS reaction. These findings are useful for the design of highly active and stable WGS catalysts that contain only trace amounts of a precious metal without the need for a reducible oxide support such as ceria.

The promotion of Ce-doped V/WTi for NH 3 -SCR performance and ammonium bisulfate (ABS) resistance is fully illustrated. The V 2 O 5 /CeO 2 /WTi-2 presents an excellent NO x conversion at 280 °C in the presence of 1000 ppm SO 2 .The introduction of ceria contributes to the vanadia species agglomeration into the oligomeric V-O-V structures and tight connects with the adjacent vanadium species to form the redox structure of Ce 4+ -O-Ce 3+ -O-V 5+ -O-V 5+ -O-Ce 3+ -O-Ce 4+ , which facilitates the electronic conduction between ceria and vanadia species. The electronic interaction via the redox structure promotes the activation of ammonia adsorbed on vanadia and nitrate species on ceria, which lowers the apparent activation energies (Ea) and significantly improves the NO x conversion rate. The addition of ceria protects active V sites poisoning and improves the stability of the adsorbed NO x species, which prevents VOSO 4 formation and competitively inhibits the adsorption of SO 2 with less metal sulfate formation on ceria. In addition, the electrons donating from vanadia to ceria species via the redox structure could make ceria species existing in electron enrichment state and boost the electrons around ceria deviating towards sulfates and strengthen the bonding between ceria and as-formed ABS species, which weakens the stability of ABS and promotes to initiate NH 3 -SCR reaction between the NH 4 + species of ABS and NO+O 2 . The faster NH 3 -SCR conversion rate promoted by the redox structure further suppresses the competitive reaction between sulfate and ammonia species, which results in no ABS formation over V/Ce/WTi-2.

Objectives: This study explored and analyzed the application value of oXiris- endotoxin adsorption technology in patients with sepsis., Methods: 23 sepsis patients hospitalized from January 2018 to September 2019 in our ICU center and received oxiris-endotoxin adsorption were enrolled as the observation group, and another 30 sepsis patients hospitalized during the same period were selected as the control group who treated with routine continuous renal replacement therapy (CRRT). The heart rate, respiratory rate, norepinephrine (NE) dosage, lactic acid, procalcitonin (PCT), urine volume, and sofa scores that evaluate organ failure after systemic infection, as well as ICU stay, organ support duration, and incidence of cardiovascular events were compared between the two groups before and after treatment., Results: The heart rate, respiratory rate and NE dosage of the two groups post-treatment were dramatically lower than those pre-treatment ( P<0.05 ), and these indexes in observation group after treatment were critically lower than those in control group ( P<0.05 ). The lactic acid, PCT, urine volume and sofa scores of the two groups were dramatically lower than those before treatment ( P<0.05 ), and the indexes in observation group after treatment were notably lower than those in control group ( P<0.05 ). The degree of serum IL-6, IL-10 and endotoxin in two groups after operation decreased remarkably than that before treatment ( P<0.05 ), and the observation group had obviously lower indicator degree than the control group ( P<0.05 ). The ICU stay, organ support duration, and incidence of cardiovascular events in the observation group were notably lower than those in the control group ( P<0.05 )., Conclusion: compared with the traditional CRRT technology, the oXiris membrane based CRRT technology can effectively improve the hemodynamic indicators of patients with sepsis, reduce the level of inflammation, and improve the metabolic function of body, thereby improving the patients' organ function. It has good clinical application value in patients with sepsis., Competing Interests: None., (AJTR Copyright © 2021.)
