Experience and training needs of nurses in military hospital on emergency rescue at high altitude: a qualitative meta-synthesis.

BACKGROUND: Nurses play an important role in the treatment of war wounds on the plateau, and they face multiple challenges and a variety of needs in their caregiving process. This study aimed to systematically integrate and evaluate qualitative research data to understand the altitude emergency rescue experience and training needs of nurses in military hospitals and provide them with targeted assistance. METHODS: We critically assessed the study using the Joanna Briggs Institute Critical Assessment Checklist for Qualitative Research. Extraction, summarization and meta-synthesis of qualitative data. Cochrane Library, PubMed, Embase, FMRS, CINAHL, PsycINFO, Chinese National Knowledge Infrastructure (CNKI), Wanfang Database (CECDB), VIP Database, and China Biomedical Database (CBM) were searched for relevant studies published from the establishment of the database to May 2023. Additionally, we conducted a manual search of the references of the identified studies. Registered on the PROSPERO database (CRD42024537104). RESULTS: A total of 17 studies, including 428 participants, were included, and 139 research results were extracted, summarized into 10 new categories, and formed 3 meta-themes. Meta-theme 1: mental state of military nurses during deployment. Meta-theme 2: the experience of military nurses during deployment. Meta-theme 3: training needs for emergency care. CONCLUSIONS: Emergency rescue of high-altitude war injuries is a challenging process. Leaders should pay full attention to the feelings and needs of military nurses during the first aid process and provide them with appropriate support.

Novel strategy to raise the content of aglycone isoflavones in soymilk and gel: Effect of germination on the physicochemical properties.

Germination holds the key to nutritional equilibrium in plant grains. In this study, the effect of soybean germination on the processing of soymilk (SM) and glucono-δ-lactone (GDL) induced soymilk gel (SG) was investigated. Germination promoted soybean sprout (SS) growth by activating the energy metabolism system. The energy metabolism was high during the three-day germination and was the most vigorous on the second day of germination. After germination, protein dissolution was improved in SM, and endogenous enzymes produced small molecule proteins. Small molecule proteins were more likely to aggregate to produce SM protein particles. Germination increased the water-holding capacity of SG induced by GDL but weakened the strength. Furthermore, the dynamic fluctuations in isoflavone content were closely monitored throughout the processing of soybean products, including SS, SM, and SG. Although the total amount of isoflavones in SM and SG processed from germinated soybeans decreased, a significant enrichment in the content of aglycone isoflavones was observed. The content of aglycone isoflavones in SG processed from germinated soybeans on the second day of germination was 736.17 ± 28.49 µg/g DW, which was 83.19 % higher than that of the control group. This study demonstrates that germination can enhance the nutritional value of soybean products, providing innovative opportunities for the development of health-promoting soybean-based products.

Cross-linked modifications of starches from colored highland barley and their characterizations, digestibility, and lipolysis inhibitory abilities in vitro.

To promote the stability and functionality of native starch from colored highland barley (CHBS), the cross-linked modifications with sodium trimetaphosphate (STMP)/sodium tripolyphosphate (STPP) and citric acid were conducted to prepare CHB resistant starches (CHRSs), whose physicochemical characteristics, digestibility, and lipolysis inhibitory potential were also assessed. Results showed that the resistant starch amounts in CHBS were significantly increased after cross-linking and differed slightly among CHRSs. Citric acid modification of CHBS resulted in significantly higher amylose amounts, solubilities, swelling powers, and water-binding capacities than those under STMP/STPP modification within the cultivars (p < 0.05), with their crystalline patterns of A-type (white and blue) and CB-type (black). STMP/STPP modified CHBS exhibited higher degrees of crystalline regions with B-type crystalline patterns. Due to the differences in structural properties and structure-based morphology, STMP/STPP cross-linked CHBS showed lower digestibility and citric acid cross-linked CHBS exhibited higher lipolysis inhibitory activities. Besides, the cross-linked modifications demonstrated more enhancements in functionalities of starches from white and blue cultivars than black cultivar.

First human case report of Crohn's disease with coexistent acute appendicitis treated by endoscopic retrograde appendicitis therapy.

Background: The coexistence of Crohn's disease (CD) and acute appendicitis (AA) is rare. In this situation, therapeutic experience is lacking and the strategy is paradoxical and intractable. Appendectomy is the gold standard for the treatment of AA whereas a nonsurgical approach is recommended for CD. Case summary: A 17-year-old boy was hospitalized for right lower abdominal pain with fever of 3 days. He had the CD for 8 years. Two years ago, he underwent surgery for anal fistula with the complication of CD. His temperature was elevated at 38.3°C at admission. On physical examination, there was McBurney tenderness with mild rebound tenderness. Abdominal ultrasonography showed that the appendix was notably enlarged and dilated at 6.34 cm long and 2.76 cm wide. These findings were suggestive of uncomplicated AA in this patient with active CD. Endoscopic retrograde appendicitis therapy (ERAT) was performed. The patient had complete pain relief immediately after the procedure without tenderness in the right lower abdomen. During 18 mo follow-up, he had no more attacks in his right lower abdomen. Conclusion: ERAT was effective and safe in a CD patient with coexisting AA. Such cases can avoid surgery and its-related complications.

Endoscopic retrograde appendicitis therapy in the management of chronic fecalith appendicitis in a patient with ulcerative colitis: The first human case report.

To assess the effectiveness of endoscopic retrograde appendicitis therapy (ERAT) as a new technique and method for chronic fecalith appendicitis complicated by active ulcerative colitis. A 46-year-old male patient was admitted with right iliac fossa pain, tenderness, and raised inflammatory markers. A computed tomography (CT) scan of his abdomen confirmed a dilated appendix, which is considered chronic fecalith appendicitis combined with active ulcerative colitis. He was treated with an endoscopic retrograde appendicitis therapy procedure. The patient recovered well after the ERAT procedure and was discharged from the hospital in two days. On follow-up one year later, there was no recurrence of pain in his abdomen. In conclusion, ERAT could be seen as a different approach and be favored as a safer and more effective option in treating UC patients with appendicitis, especially those who are later in the course of the disease. Because of the ERAT procedure, such cases can avoid surgery and surgery-related complications. More research and issues must be addressed to demonstrate the efficacy and effectiveness of ERAT in appendicitis combined with UC.

Multiband Superconductivity with Sign-Preserving Order Parameter in Kagome Superconductor CsV_{3}Sb_{5}.

The superconductivity of a kagome superconductor CsV_{3}Sb_{5} is studied by scanning tunneling microscopy and spectroscopy at ultralow temperature with high resolution. Two kinds of superconducting gaps with multiple sets of coherent peaks and residual zero-energy density of states (DOS) are observed on both half-Cs and Sb surfaces, implying multiband superconductivity. In addition, in-gap states can be induced by magnetic impurities but not by nonmagnetic impurities, suggesting a sign-preserving or s-wave superconducting order parameter. Moreover, the interplay between charge density waves (CDW) and superconductivity differs on various bands, resulting in different density-of-states distributions. Our results suggest that the superconducting gap is likely isotropic on the sections of Fermi surface that play little roles in CDW, and the superconducting gaps on the sections of Fermi surface with anisotropic CDW gaps are likely anisotropic as well. The residual spectral weights at zero energy are attributed to the extremely small superconducting gap on the tiny oval Fermi pockets. Our study provides critical clues for further understanding the superconductivity and its relation to CDW in CsV_{3}Sb_{5}.

OBJECTIVE: The aim of study was to investigate bacterial diversity of Populus Euphratica forest in the hinterland of Taklimakan desert. All the isolateds were be used as inoculants for silage and biofertilizer. METHODS: Strains were isolated by culture-dependent method. Gram staining, NaCl tolerance,enzyme activity (including amylase, esterase, cellulase) were determined by strand methods. Phylogenetic trees based on 16S rRNA gene sequences were constructed by using the neighbour-joining. RESULTS: A total of 27 strains were obtained. Phylogenetic analysis of the bacterial 16S rRNA gene showed that all isolates fell into one of the following four bacterial lineages: Actinobacteria (16 strains), Proteobacteria (4 strains), Firmicutes (6 strains) and Bacteroidetes (1 strains). Gram staining indicated that 5 strains were gram-negative and the others were gram-positive. Among these, 15 strains showed amylase activity, 9 strains showed esterase activity and 9 strains showed cellulase activity. All strains growth occurred at in presence of 2% NaCl, 22 strains growth occurred at in presence of 5% NaCl and only 1 strain tolerated up to 15% NaCl. CONCLUSION: The bacterial population diversity is abundant in soil of Populus Euphratica Forest in the hinterland of Taklimakan Desert, which is worthy of further investigation.

[Diversity of halophilic Actinomycetes from mud volcano in Xinjiang].

OBJECTIVE: To know halophilic actinomycetes and their enzyme-producing ability from mud volcano in Usu County, Xinjiang, China. METHODS: Soil samples in mud volcano were isolated with five isolation media containing 5% and 10% NaCl (w/v) with dilution-plate method. The activities of lipase, galactosidase, amylase, esterase and cellulase from isolated strains were qualitatively detected by using five selective media. Base on morphological characteristics, test of salt tolerance, screening of enzymatic characters and sequencing of 16S rDNA gene, strains were selected for phylogenetic analysis. RESULTS: A total of 43 halophilic actinomycetes and 3 extreme halophilic actinomycetes were obtained. Screening results for enzyme activity showed that 4 halophilic actinomycetes produced lipase, 30 strains produced galactosidase, 27 strains produced amylase, 6 strains produced esterase, 4 strains produced cellulose and 1 strain produced 4 enzymes simultaneously. According to 16S rDNA sequence analysis, 24 of 25 detected sequences were affiliated with Nocardiopsis, and the other one was Streptomyces. In the phylogenetic tree, strain 10006 producing 2 enzymes and Nocardiopsis exhalans (AY03600) showed 96.64% similarity (less than 97%), which indicated that strain 10006 was a possible new species. CONCLUSION: There are plenty of galactosidase or amylase-producing halophilic actinomycetes and higher enzyme-producing diversity of Nocardiopsis in Usu mud volcano. In addition, there are potential microbial resources in this extreme environment.
