Metal nanoclusters (NCs) are stable aggregates at the molecular level, consisting of several to hundreds of metal atoms bound together by physical or chemical interaction. These nanoclusters exhibit unique physicochemical properties that have garnered significant attention in various fields, including biology, catalysis, sensing, and drug delivery. In the field of catalytic reactions, atomically precise metal nanoclusters have acted as an archetypical model for elucidating the structural evolution and structure-property relationship of nanomaterials. However, due to the factors such as the uncertainty of the growth mechanism, the complexity of the crystallization process, and the inherent poor stability, the cluster research faces some challenges in the precise synthesis, structural analysis as well as the comprehension of catalytic reaction mechanism which hinder the full exploration and understanding of these fascinating properties of clusters. Recent years, mass spectrometry (MS) has emerged as a crucial tool in biomolecular analysis and the detection of organic reaction intermediates due to its high sensitivity, high resolution, and fast response. In cluster chemistry, the researchers have also introduced this technique into the study of metal nanoclusters with precise atomic numbers, which have played an important role in the synthesis of clusters and the analysis of their structures as well as reaction mechanisms. The ion source, as the "heart" of the MS, can ionize the analyte and then be detected by MS. Currently, the main ionization methods used for cluster analysis are electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). These two "soft" ionization techniques can obtain the quasi-molecular ion peaks of the clusters without destroying the structure of the clusters, thus determining the composition of the clusters. In addition, MS enables real-time characterization of the reaction process in solution, allowing for online monitoring of complex reaction components, providing an experimental basis for synthesis processes and catalytic reaction mechanisms of metal clusters. Notably, gas-phase ion-molecule reactions can provide catalytic primitive steps and reaction kinetics enabling in-depth analysis of microscopic reaction mechanisms at a strictly molecular level. For the structural characterization of clusters, tandem mass spectrometry (MS/MS) combined with quantum chemical calculation provides a powerful tool to study and understand the structural evolutions of clusters. By comparing and verifying the experimental and computational results, the correlation between the catalyst structure and its performance can be established, deepening our understanding of the catalytic reaction mechanism and process. This paper was focused on the latest development of soft ionization MS in monitoring intermediates of cluster synthesis, structure analysis, and catalytic reaction mechanism, and the emerging directions in this fascinating area of research were highlighted.

The representative radioactive elemental iodine and methyl iodine are selected as adsorbates and the static adsorption capacity, adsorption heat and kinetics of silver based molecular sieves are investigated. The micro morphology, element composition and adsorption mechanism of the materials are characterized and analyzed by SEM, EDX mapping and XPS tests. The results show that the adsorption capacity of the material for elemental iodine and methyl iodine at room temperature can reach 1000 mg/g and 380 mg/g respectively, and the adsorption process for methyl iodine conforms to the quasi second order kinetic equation and Langmuair adsorption isotherm model. Silver based molecular sieves process trace radioactive iodine through chemical adsorption, while the main adsorption mode for higher concentration radioactive iodine is physical adsorption.

Objective: To study the expressions of IL-33 and its receptor ST2L in peripheral blood T cells and skin lesions of patients with psoriasis. Methods: The expression and distribution of IL-33 and ST2L in psoriasis vulgaris(PV group), psoriasis pustulosa(PP group) and nevus resection]control group(CON group)]were detected by immunohistochemical method. Western blot and RT-PCR were used to detect the expression of IL-33 and IL-33 mRNA in Jurkat T cells and HaCat keratinocytes induced by IL-17A, respectively. The same method was used to detect the expression of ST2L and ST2L mRNA in Jurkat T cells, PV group T cells, PP group T cells and CON group T cells after IL-33 induction. Results: In the skin lesions of patients in PV group and PP group, we observed positive staining of IL-33 and its receptor ST2L protein in epidermis and dermis cells with different densities; a small amount of IL-33 protein was expressed in T cells of CON group, but in psoriasis group, including PV group and PP group, IL-33 protein was significantly expressed in T cells, and the expression level of PP group was higher than that of PV group, the difference was statistically significant(P<0.05); IL-33 induced Jurkat T cells, PV group and PP group T cells to express a certain amount of ST2L protein and mRNA in a dose-dependent manner; the expression of ST2L protein in PV group and PP group were higher than the level of ST2L induced by IL-33 in CON group, and the difference was statistically significant(P<0.05). IL-17A induced Jurkat T cells to produce IL-33 protein and mRNA in a certain amount of effect and aging relationship; IL-17A induced the expression of IL-33 protein and mRNA in HaCat keratinocytes in a dose-dependent manner. IL-33 protein was mainly expressed in the nucleus of HaCat keratinocytes, and some of the cytoplasm had some expression, and the expression was significantly increased after high concentration of IL-17A stimulation. Conclusion: The expression levels of IL-33 and its receptor ST2L in peripheral blood T cells and skin lesions of patients with psoriasis are significantly increased, suggesting that IL-33 may play an important role in the occurrence and development of psoriasis.

To evaluate the effects of ultrasus-guided thoracic paravertebral nerve block (TPVB) and erectile spinal-plane block (ESPB) on perioperative stress response and analgesia in patients undergoing thoracoscopic surgery. Methods Ninety patients underwent thoracoscopic surgery under elective general anesthesia were included and randomly divided into the control group (group C), the ESPB group (group E) and the TPVB group (group T), with 30 cases in each group. Before anesthesia induction, no treatment was given to the group C, and the group E and the group T were treated with ultrasound guided ESPB and TPVB on the affected side, and injected with 20 mL of 0.5% ropivacaine. Patient controlled analgesia (PCIA) was connected after operation. The venous blood samples were collected immediately before operation (T0), 30 minutes after operation (T1) and at the time of tracheal catheter removal (T2) to test the concentration of blood glucose (Glu) and serum cortisol (Cor). The type of surgery, the duration time of surgery, the number of patients who needed to use phenylephrine and the amount of remifentanil for hypotension during operation were recorded. Visual analog scores (VAS) of patients at rest and coughing status at T2, 12 hours after operation (T3), 24 hours after operation (T4), 48 hours after operation (T5), the total number of PCIA compression and the total amount of PCIA sufentanil infusion within 48 hours after operation, the use of rescue analgesia, and the occurrence of adverse reactions were recorded. Results Compared with T0, concentrations of Cor and Glu at T1 and T2, were increased in patients (P＜0.05). Compared with the group C, Glu was significantly decreased in the group T, the resting VAS pain scores of T2, T3, T4 and T5 were decreased in the group T and the group E. The coughing VAS pain scores of T2 and T4 were decreased, and the intraoperative dosage of reifentanil, the number of PCIA compression and the total infusion of sufentanil were decreased. The remedial analgesic rate was decreased in the T group (P＜0.05). Compared with the group T, the resting VAS scores of T2, T3 and T4 were increased in the group E, and the coughing VAS scores of T3 were increased, the number of PCIA compression, remifentanil usage and the total infusion of PCIA sufentanil were increased. The percentage of intraoperative use of norepinephrine for hypotension was decreased (P＜ 0.05). Conclusion TPVB can inhibit the stress response of patients undergoing thoracoscopic surgery. TPVB could provide better postoperative analgesia than ESPB, and has a significant inhibitory effect on intraoperative blood pressure. [ABSTRACT FROM AUTHOR]

Objective: Atrial fibrillation is one of the most common arrhythmias. The mechanism of atrial fibrillation is not yet clear. A number of previous studies have shown that adipokines, including leptin, visfatin, are closely related to cardiovascular diseases.In this study, the relationship between leptin, visfatin and atrial fibrillation was investigated. Methods: In this study, the secretion levels of leptin and visfatin in peripheral blood and epicardial adipose tissue of AF group and control group were detected. To explore the relationship between leptin, visfatin and AF. Results: The average concentration of visfatin in peripheral blood serum of atrial fibrillation group was 15.95±10.44 ng/mL, and the sinus rhythm group was 20.28±12.90 ng/mL, and there was not statistically significant (P=0.169); The average concentration of leptin in peripheral blood in the atrial fibrillation group was 1.48 ng/mL, and in the sinus rhythm group was 2.56ng/mL. The comparison between the two was statistically significant (P=0.0027). Serum leptin levels in the sinus group were significantly higher than those in the atrial fibrillation group; In epicardial adipose tissue, the expression of leptin in the atrial fibrillation group was significantly lower than that in the control group (P=0.032), while the expression of visfatin was not statistically different between the two groups (P=0.06). Conclusions: The incidence of atrial fibrillation can be reduced by high levels of leptin in peripheral blood serum and epicardial adipose tissue. The levels of visfatin in peripheral blood serum and epicardial adipose tissue in patients with atrial fibrillation was not significantly different from those with sinus rhythm. Therefore there may not be a correlation between visfatin and atrial fibrillation. [ABSTRACT FROM AUTHOR]

【Objective】To explore the effects of continuous application of soil conditioner quicklime and organic fertilizer on the growth, development, and yield components of maize in acidic soil in the southeastern region of Liaoning.【Methods】From 2019 to 2021 field experiments were conducted in Fengcheng City, Liaoning Province. Four treatments were set up including no application of soil conditioner (CK), quicklime (CaO), organic fertilizer (Organic), and organic fertilizer+quicklime (Organic+CaO) . The effects of continuous application of soil conditioner on maize plant traits, dry matter accumulation, yield components, and other indicators were analyzed.【Results】From 2019 to 2021, the maize yield of CaO treatment were all higher than CK. The yield of Organic and Organic+CaO treatments were higher than CK in the first two years and were lower than the CK in the third year of continuous application. The yield increase of CaO treatment were in the range of 2.12% to 19.74%. The yield increase rates of Organic+CaO treatment were 15.74% and 7.89% in the first two years, respectively. But there was no yield increase effect in the third year of application. The year, soil conditioner, and their interaction had extremely significant effect (P<0.01) on maize yield. The yield of CaO and Organic+CaO treatments were significantly higher (P<0.05) than CK and the Organic treatments. The ear number of CaO treatment was significantly higher (P<0.05) than CK. CaO and Organic+CaO treatments had significantly higher (P<0.05) kernel number per ear and kernel number per hectare than that of CK and Organic treatment. 1 000-kernel weight in Organic+CaO treatment was significantly higher (P<0.05) than all other treatments. Yield was significantly positively correlated (P<0.05) with kernel number per ear (R2=0.614) and kernel number per hectare (R2=0.746) . Continuous application of soil conditioner could improve plant height, ear height, and the ratio of ear height to plant height of maize. And the effect on ear height was more than the effect on plant height. Leaf area index (LAI) increased rapidly in early growth stages and decreased slowly in later growth stages. The effects were more obvious for Organic+CaO and Organic treatments. Applying soil conditioner promoted the dry matter accumulation and post floral dry matter accumulation of all the growth stages. The effect of Organic+CaO treatment was better than that of Organic and CaO treatments.【Conclusion】Continuous application of CaO and Organic+CaO on acidic soil promoted the maize growth and development. However, from the yield prospective, when using Organic+CaO as soil conditioner in the southeastern region of Liaoning, continuous application for more than two years should be avoided.

Objective To observe the effect of thoracic paravertebral block (TPVB) combined with erector spinae plane block (ESPB) on postoperative analgesia and quality of recovery in patients underwent video-assisted thoracic surgery. Methods Ninety patients underwent video-assisted thoracic surgery were selected and randomly divided into the E group, the T group and the TE group (preoperatively receiving ultrasound-guided ESPB, TPVB and TPVB+ESPB, respectively), with 30 patients in each group. In the three groups, 0.5% ropivacaine 25 mL was used as local anesthetic. In the TE group, TPVB combined with ESPB was executed, and 5 and 20 mL local anesthetics were used successively. Patient-controlled intravenous analgesia (PCIA) was used as a rescue analgesia postoperatively. Data of hypesthesia at lateral chest wall at 30 min after completion of block, intraoperative incidence of hypotension and dosage of anesthetics were recorded. Patients were followed up for Numeric Rating Scales (NRS) score, time to first rescue analgesia, number of rescue analgesia, quality of recovery-15 score, analgesia satisfaction score, postoperative nausea and vomiting (PONV) scores in the first 24 h postsurgery and incidence of postoperative chronic pain at 6 months. Results The incidence of preoperative hypesthesia was higher in the TE group and the T group than that in the E group (P＜0.05). The intraoperative use of remifentanil was lower in the T group than that of the E group and the TE group, but the utilization rate of vasoconstricting drugs was the highest (P＜0.05). NRS scores at rest and coughing were lower in the T group than those in the E and TE groups (P＜0.05). There were no significant differences in the time to first rescue analgesia and the number of rescue analgesia between the three groups (P＞0.05). Compared with the E group, the T group had a better postoperative QoR-15 scores (P＜0.05), and the group TE had lower incidence of postoperative chronic pain (P＜0.05). There were no statistical differences in analgesia satisfaction scores and PONV scores between the three groups (P＞0.05). Conclusion The effects of TPVB+ESPB on postoperative analgesia and quality of recovery in patients underwent thoracoscopic surgery are not better than those of ESPB and TPVB, but it has a faster onset time of sensory block than ESPB and reduces the occurrence of postoperative chronic pain.
