Effects of an Omaha System-based follow-up regimen on self-care and quality of life in gastrointestinal surgery patients.

BACKGROUND: Currently, a variety of new nursing methods and routine nursing have been widely used in the nursing of gastrointestinal surgery patients. AIM: To investigate the effect of follow-up protocol based on the Omaha System on self-care ability and quality of life of gastrointestinal surgery patients. METHODS: A total of 128 patients with inflammatory bowel disease in gastrointestinal surgery in gastrointestinal surgery from March 2019 to August 2021 were divided into A (n = 64) and B (n = 64) groups according to different nursing methods. The group A received a follow-up program Omaha System-based intervention of the group B, whereas the group B received the routine nursing intervention. Medical Coping Modes Questionnaire, Crohn's and Colitis Knowledge Score (CCKNOW), inflammatory bowel disease questionnaire (IBDQ), Exercise of Self-nursing Agency Scale (ESCA), The Modified Mayo Endoscopic Score, and Beliefs about Medicine Questionnaire (BMQ) were compared between the two groups. RESULTS: Following the intervention, the group A were facing score significantly increased than group B, while the avoidance and yield scores dropped below of group B (all P < 0.05); in group A, the level of health knowledge, personal care abilities, self-perception, self-awareness score and ESCA total score were more outstanding than group B (all P < 0.05); in group A the frequency of defecation, hematochezia, endoscopic performance, the total evaluation score by physicians and the disease activity were lower than group B (all P < 0.05); in the group A, the total scores of knowledge in general, diet, drug, and complication and CCKNOW were higher than group B (all P < 0.05); in group A, the necessity of taking medicine, score of medicine concern and over-all score of BMQ were more significant than group B (all P < 0.05); at last in the group A, the scores of systemic and intestinal symptoms, social and emotional function, and IBDQ in the group A were higher than group B (all P < 0.05). CONCLUSION: For gastrointestinal surgery patients, the Omaha System-based sequel protocol can improve disease awareness and intervention compliance, help them to face the disease positively, reduce disease activity, and improve patients' self-nursing ability and quality of life.

Mammary Paget's Disease of Young Females: Case Reports and Comparison With Middle-Aged and Elderly Patients.

Purpose: Mammary Paget's disease (PD) in young women has seldom been reported. The aim of this study was to improve the knowledge of the clinicopathological characteristics in young patients with PD to provide a basis for the precise treatment of young patients. Methods: The medical records and pathological slides of 8 young patients (younger than 40 years old) with PD were reviewed. The data of 20 patients over 40 years old within the same period were used as controls. Results: The average age was 32.00 ± 3.96 years for the young patient group, with the youngest aged 27 years. The first symptom, physical examination, Paget cell morphology, and immunohistochemical marks were the same in different age groups. But young patients have varied tumor distribution patterns, fewer interstitial inflammatory cells, and advanced pathological local lymphatic metastasis than older patients in the same period. Conclusions: PD in young women has unique histopathological features. These manifestations seem to provide personalized treatment for PD treatment in young patients. More research is needed to clarify the significance of this research.

Comparative analysis of mitogenomes among six species of grasshoppers (Orthoptera: Acridoidea: Catantopidae) and their phylogenetic implications in wing-type evolution.

The degree of wing development has a close relationship with insects' movement ability and range, and it should also be closely related to mitochondrial-related genes. The complete mitochondrial genomes of six species of Catantopidae were sequenced, annotated and analyzed. Then, combined with 37 mitogenomes of grasshoppers, the ratio of nonsynonymous substitution to synonymous substitution (Ka/Ks) of the combined sequences of protein coding genes (PCGs) was calculated by DnaSP5, and the phylogenetic relationships were reconstructed by maximum likelihood (ML) and Bayesian (BI) methods based on PCGs+rRNAs. The results showed that the sizes of the six complete mitogenomes are Stenocatantops mistshenkoi Willemse F., 1968, 15,573 bp; Traulia lofaoshana Tinkham, 1940, 15,645 bp; Sinopodisma rostellocerca You, 1980, 15,622 bp; Anapodisma miramae Dovnar-Zapolskij, 1932, 15,189 bp; Qinlingacris elaeodes Yin & Chou, 1979, 15,221 bp; and Eozubovskya planicaudata Zhang & Jin, 1985, 15,830 bp; their structures are the same as those of Acridoidea. The AT bias of the wing-degenerated group (lobiform and apterous) is higher than that of the longipennate group, and more nonsynonymous substitutions accumulated in the wing-degenerated group than in the longipennate group (P = 0.000), which indicates that the wing-degenerated group has undergone weaker evolutionary selection than the longipinnate group. The phylogenetic tree shows that the wing-degenerated group in the Catantopidae are multiorigin and present parallel evolution.

[Pharmacological effect of combined administration of natures, tastes and components of Chinese herbal compounds].

The combined administration of traditional Chinese medicine (TCM) aims at comprehensive adjustment of body based on the theory of TCM and the theory of Chinese medicine property. The natures and tastes of TCM are the core of the theory of TCM property. The combined administration of natures and tastes of TCM is one of the important theories of prescription compatibility. The objective of study on the combined administration of natures and tastes of prescriptions according to symptoms of disease is to clarify the compatibility mechanism of prescriptions. The study on the compound compatibility of TCM under the guidance of theory of TCM focuses on the relationship between the composition, dosage and compatibility of TCM by using modern high-tech means. It demonstrates the effective combination of TCM theory and modern technology, and the inheritance and innovation of TCM theory. The study of the effect and mechanism of compatibility of natures and tastes of TCM under the guidance of TCM theory is helpful for the analysis of the compatibility effect and mechanism of TCM based on the pharmacological effect of natures and tastes of TCM. The correlation between the pharmacological effect of natures and tastes of TCM and the pharmacological effect of components were studied by modern informatics, which is beneficial to promote the development of theory of TCM compound. The study of the compatibility between natures, tastes and component of TCM shall pay attention to the combination of pharmacological effects of natures, tastes and component of TCM, so as to define the scientific connotation of the compatibility of TCM, and make full use of the characteristics and advantages of TCM. The methods and pharmacological effects of the combined administration of TCM compounds are reviewed to provide the theoretical basis for the development of new drugs and clinical application.

A PEG-based method for the isolation of urinary exosomes and its application in renal fibrosis diagnostics using cargo miR-29c and miR-21 analysis.

PURPOSE: To assess a new and highly specific, but low-cost, easily performed and suitable for large-scale applications method for renal fibrosis (RF) diagnostics. METHODS: Thirty-five RF and twenty non-RF patients were enrolled in the study. An appropriate polyethylene glycol (PEG) was used to isolate urinary exosomes. The efficiency of isolation process was evaluated by the morphology and size observation, as well as the detection of specific markers (CD63, CD9). The expression level of exosomal miR-29c, miR-21 and the endogenous control snRNA-U6 were detected by qRT-PCR. The diagnostic potency of urinary exosomal miR-29c and miR-21 was estimated by the ROC method. Spearman's rank-order correlations analysis was used to assess the correlation between the miRNAs and clinical parameters, including pathological index. RESULTS: PEG-based method for isolation urinary exosome was effective and could be completed with a relatively low-speed centrifugal machine. Exosomal miR-29c and miR-21 were detected in all samples. The analysis of miRNAs in urinary exosomes revealed significant dys-regulation of miR-29c and miR-21 associated with RF. Exosomal miR-29c and miR-21 could predict degree of RF with AUC of 0.8333 and 0.7639 (P < 0.05). Correlation analysis showed that the level of miR-29c had a significant negative relationship with eGFR and the interstitial relative area. CONCLUSIONS: The PEG-based method for isolation urinary exosome is an inexpensive and easily performed approach. The application for cargo miRNA analysis is feasible. Urinary exosomal miR-29c may present a promising diagnostic approach.

Electrically pumped random lasing with an onset voltage of sub-3 V from ZnO-based light-emitting devices featuring nanometer-thick MoO3 interlayers.

We have previously reported on electrically pumped random lasing (RL) with onset voltages at least 3.3 V from ZnO-based light-emitting devices with metal-insulator-semiconductor (MIS) structures in the form of Au/SiO2/ZnO. Here, by inserting an ∼5 nm thick MoO3 layer between SiO2 and ZnO films in the aforementioned MIS structured device, the RL onset voltage is decreased to only ∼2.6 V and, moreover, the output optical power is multiplied several times. Such improved RL performance is ascribed to the enhanced injection of holes into ZnO via the MoO3 interlayer that features a low-lying conductive band and therefore a large work function.

A comparative study of the interaction of two structurally analogous ruthenium complexes with human telomeric G-quadruplex DNA.

Two new polypyridine ligands and their corresponding ruthenium(II) complexes have been prepared and characterized. The interactions of both complexes with human telomere quadruplex DNA (both the antiparallel basket and the mixed-hybrid G-quadruplex) have been studied by circular dichroism (CD), CD melting, UV-visible (UV-Vis), fluorescent intercalator displacement (FID) assays and molecular docking studies. The results show that both complexes can stabilize G-quadruplexes DNA and two complexes show different binding affinity for different G-quadruplexes DNA. The 1:1 stoichiometry was confirmed in the buffered solutions by the UV-Vis spectrophotometer using Job's plot method and molecular docking studies. We have also investigated the interaction between the complexes and duplex DNA to gain some insight into the selectivity of the complexes for G-quadruplex structures. FID studies have shown that the complexes have a modest selectivity for G-quadruplex versus duplex DNA.

Bis(N-phenyl-ethane-1,2-diamine)dithio-cyanato-nickel(II).

The asymmetric unit of the title mononuclear Ni(II) compound, [Ni(NCS)(2)(C(8)H(12)N(2))(2)], contains two independent half-mol-ecules, the Ni atoms of which lie on crystallographic inversion centres. Each Ni(II) ion is chelated by two N atoms from two N-phenyl-ethane-1,2-diamine ligands and is also coordinated by two N atoms from two thio-cyanate ligands, giving a distorted octa-hedral geometry. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (100) by N-H⋯S inter-actions.
