ObjectiveTo improve the response capabilities to disasters and prevent major epidemics， it is of practical use to study the capability evaluation system of the national emergency medical rescue team that combines theoretical training and practical exercises， to enhance the overall quality of the teams. MethodsFirst， a capability assessment system for the national emergency medical rescue team was constructed based on the INSARAG External Classification （IEC） standards of the national emergency medical rescue team. Then， based on the outcome based education （OBE） concept， we conducted innovative research on the curriculum design and exercise programs for team building and member training. Finally， an empirical analysis was conducted on the effectiveness of the evaluation system and training exercises based on the statistical analysis of the comprehensive quality evaluation of the Shanghai national emergency medical rescue team from 2020 to 2023， as well as the empirical analysis of the rescue exercise on the Cruise of spectrum. ResultsBased on the linear regression analysis of each core competency indicators， the five core competencies in the evaluation system， including rescue skills， medical and health knowledge， disaster coping ability， team cooperation ability， and mental resilience training， were positively correlated with the cumulative number of trainings （r=0.71， r=0.76， r=0.81， r=0.84， r=0.96，all P<0.05）， indicating that the training was effective and the course design was reasonable. Empirical cases showed that the three-dimensional rescue drill model had remarkable results in the actual combat application and ability improvement of team members. ConclusionThe training courses and drills designed based on the three-level assessment system are effective in improving the comprehensive capabilities of the national emergency medical rescue team.

Objective:To investigate the current situation of community nursing needs of patients with middle and advanced Parkinson ′s disease, analyze the factors affecting the demand, and further explore the possible pathways of action between the factors, so as to provide the basis for formulating targeted community intervention measures in a more comprehensive way. Methods:A cross-sectional survey of 242 patients with middle and advanced Parkinson ′s disease from the Second Hospital Affiliated to the Army Medical University from November 2022 to January 2023 were selected by convenience sampling method, and the Community Care Need Scale, General Data Questionnaire, Readiness for Hospital Discharge Scale, Medical Coping Modes Questionnaire and the Self-management Effectiveness Questionnaire of Parkinson ′s disease patients were used. SPSS 26.0 was used to analyze the data, and investigated the relationship between readiness for hospital discharge, self-management efficacy, active coping styles, and community nursing needs. Results:A total of 234 valid questionnaires were collected, including 108 males and 126 females, aged 39-93 (67.25±8.93) years. The average score of all dimensions from high to low was: disease treatment dimension (4.16±0.42), daily care dimension (4.05±0.97), fall prevention dimension (4.04±0.80), extended care dimension (3.95±0.65), emotional support dimension (3.77±0.65) and self function (3.75±0.72). Univariate analysis indicated that there were statistically significant differences in community nursing needs scores among middle and advanced Parkinson ′s disease patients with different educational level and different family income ( F=5.11, 3.05, both P<0.05). Readiness for hospital discharge, self-management efficacy and positive coping style were negatively correlated with community nursing needs of patients with middle and advanced Parkinson′s disease ( r=-0.567, -0.412, -0.398, all P<0.01), and self-management efficacy and positive coping style played a partial mediating role between readiness for hospital discharge and community nursing needs. Conclusions:There is a wide range of community nursing needs that patients with middle and advanced Parkinson ′s disease, and patients with primary school and below, high school and above, and low family income are higher. It is suggested that the community disease management process should focus on this group of people. Medical institutions should help patients with middle and advanced Parkinson ′s disease improve their ability to manage the disease by improving discharge preparation services, so that they can smoothly transition from hospital to home, thereby reducing the needs for community nursing.

The protein kinase B(Akt)pathway can regulate the growth,proliferation,and metabolism of tumor cells and stem cells through the activation of multiple downstream target genes,thus affecting the development and treatment of a range of diseases.Thioesterase superfamily member 4(THEM4),a member of the thioesterase superfamily,is one of the Akt kinase-binding proteins.Some studies on the mechanism of cancers and other diseases have shown that THEM4 binds to Akt to regulate its phosphorylation.Initially,THEM4 was considered an endogenous inhibitor of Akt,which can inhibit the phosphorylation of Akt in diseases such as lung cancer,pancreatic cancer,and liver cancer,but subsequently,THEM4 was shown to promote the proliferation of tumor cells by positively regulating Akt activity in breast cancer and nasopharyngeal carcinoma,which contradicts previous findings.Considering these two distinct views,this review summarizes the important roles of THEM4 in the Akt pathway,focusing on THEM4 as an Akt-binding protein and its regulatory relationship with Akt phosphorylation in various diseases,especially cancer.This work provides a better understanding of the roles of THEM4 combined with Akt in the treatment of diseases.

OBJECTIVE: To present on a prenatally diagnosed case with complex structural rearrangements of chromosome 8. METHODS: Chromosome karyotyping, chromosomal microarray analysis (CMA) and fluorescence in situ hybridization (FISH) were carried out for a fetus with increased nuchal thickness. RESULTS: The karyotype of the amniotic fluid sample showed extra materials on 8p. FISH revealed a centromeric signal at the terminal of 8p with absence of telomeric signal. CMA revealed partial deletion of 8p23.3 [(208049_2256732)×1], partial duplication of 8p23.3p23.2 [(2259519_3016818)×3], and partial duplication of 8q [8q11.1q12.2(45951900_60989083)×3]. CONCLUSION The complex structural rearrangements of chromosome 8 in this case has differed from the commonly seen inv dup del(8p).

Single-cell RNA sequencing (scRNA-seq) is used for transcriptome profiling at the individual cell level, which is capable of screening in differentially gene expression that results from genetic mutation. Islet-based developmental atlas and heterogeneity characterization are currently the main applications of scRNA-seq in diabetes. scRNA-seq also can be used to mark and purify the functional β cells from resident adult stem cells in the pancreatic islets, which is expected to improve the outcome of islet β cells transplantation in type 1 diabetic patients. In addition, the technique can aid in learning diabetic β cell dedifferentiation and immunomodulatory functions. Although the study of scRNA-seq in diabetic retinopathy, nephropathy, atherosclerosis, and peripheral neuropathy is still at a nascent stage, scRNA-seq has great potential in a wide range of biomedical and clinical applications.

Objective: Anesthesia-induced cognitive impairments are common for elder patients after surgery. Oxidative stress is the predominant factor contributing to the impairments. This study was to assess the therapeutic potential of an anti-oxidative naturally occurring flavonoid, chrysin, in attenuating sevoflurane-induced cognitive impairments in rat models. Methods: Rat models of cognitive impairments were constructed by exposing aged rats (18 months old) to sevoflurane for 2 h. Chrysin was administered via oral gavage at the dose of 25, 50, and 100 mg/kg/day for seven days. The elevated plus maze test was used to assess anxiety and explorative behaviors. Spatial memory tests were performed using novel object recognition test, object location memory task, and water maze experiments. Oxidative stress was evaluated by measuring levels of malondialdehyde, nicotinamide adenine dinucleotide phosphate, 4-hydroxynonenal, and glutathione using colorimetric assays. Quantitative real-time polymerase chain reaction and Western blot were used to analyze how chrysin affects nuclear factor E2-related factor (Nrf) signaling. Results: While sevoflurane anesthesia led to significant decline in cognitive performance in object recognition test, object location memory task, and water maze test, chrysin exerted significant effects in alleviating the impairments. Oxidative stress was also reduced in the hippocampus tissue of rats after chrysin intake. Nrf signaling was activated by chrysin treatment in sevoflurane-induced cognitive impairment models. Conclusion Chrysin was effective in alleviating cognitive impairments induced by sevoflurane anesthesia, which was at least in part facilitated by its effects in reducing oxidative stress via activating Nrf signaling.

Objective To investigate the distribution characteristics of antibiotics in source water and their health risks to human body in Yichang City, and to provide a scientific basis for the prevention and control of new types of pollution such as antibiotics in drinking water. Methods Solid phase extraction (SPE) was used for enrichment, and ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was used to detect and analyze the content of five types of antibiotics including sulfonamides, tetracyclines, chloramphenicol, quinolones and β-lactams in the main drinking water sources of Yichang City. The human health risk assessment of these antibiotics was conducted. Results All five types of antibiotics were detected in the source water of Yichang City, and the detection rate was 6.25% to 81.25%. The total detection rate of β-lactam antibiotics was the highest, and the highest detection concentration of norfloxacin was 213.9 ng/L. The health risk assessment of 11 antibiotics detected in the source water showed that these antibiotics would not cause obvious health harm to human body, but the risk entropy (RQ_H) tended to increase with the younger age. Conclusion The distribution level of antibiotics in source water of Yichang City will not cause obvious health harm to human body.

Objective:To explore the effect of gratitude extension-construction theory in ovarian cancer patients undergoing chemotherapy.Methods:From January 2018 to May 2021, convenience sampling was used to select patients undergoing chemotherapy for ovarian cancer in the Shanxi Provincial People's Hospital as the study subject. Patients were divided into the control group ( n=64) and observation group ( n=65) according to the random number table method. The control group received routine nursing, while the observation group was treated with nursing guided by gratitude extension-construction theory on the basis of the control group. The effects of intervention were compared using the Perceived Stress Scale-10 (PSS-10), General Self Efficacy Scale (GSES), Quality of Life BREF (QOL-BREF), Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA). The occurrence of adverse reactions between the two groups of patients was observed. Results:After intervention, the PSS-10, HAMD and HAMA scores of patients in the observation group were lower than those in the control group, while the GSES, QOL-BREF scores were higher than those in the control group, with statistically significant differences ( P<0.05). The total incidence of adverse reactions in the control group was higher than that in the observation group, with a statistically significant difference ( P<0.05) . Conclusions:Gratitude extension-construction theory-based nursing can improve patients' self-efficacy, alleviate negative emotions, reduce self-perceived stress, and reduce the occurrence of adverse reactions, which is worthy of clinical practice.
