Objective To explore the potential category characteristics of self-management behavior in patients with lung cancer based on potential profile analysis,and to analyze the characteristic differences and influencing factors of self-management behavior in patients with different categories of lung cancer.Methods A total of 260 patients with lung cancer who had completed the main treatment program and were about to enter the follow-up period in a tertiary A general hospital in Zhejiang Province from July 2022 to May 2023 were selected by convenience sampling method as the investigation subjects.General Information Questionnaire,Lung Cancer Survivor Self-management Behavior Assessment Scale,Strategies Used by People to Promote Health,Hospital Anxiety and Depression Scale and Social Support Rating Scale were used for investigation.Potential profile analysis was used to explore the potential categories of self-management behavior in lung cancer patients and analyze its influencing factors.Results 252 patients were finally included.The results of potential profile analysis showed that lung cancer patients'self-management behavior could be divided into 3 potential categories,namely low self-management behavior-low emotion management group(11.90％),medium self-management behavior-low resource management group(45.24％),and high self-management behavior-low hope management group(42.86％).Logistic regression analysis showed that education level,previous surgery,tumor stage,anxiety level,depression level,self-efficacy level and social support level were the influencing factors of lung cancer patients'self-management behavior(P＜0.05).Conclusion The self-management behavior of lung cancer patients is at a moderate level,and there are obvious classification characteristics.It is suggested that medical staff should carry out personalized intervention measures according to the characteristics of self-management behavior of patients of various categories,so as to improve the level of self-management behavior of lung cancer survivors.

Objective:To evaluate the effectiveness of oral-nasal oxygen supply mouth guard in painless gastroscopy for snoring patients.Methods:The snoring patients who underwent painless gastroscopy at two Endoscopy Centers of Shanghai East Hospital, Tongji University in July 2022 were randomly divided into the observation group (using oral-nasal oxygen supply mouth guard) and the control group (using ordinary nasal oxygen tube and mouth guard). Parameters such as the wearing time and the removal time of the mouth guard, lowest pulse oxygen saturation (SpO 2), incidence of hypoxemia, and the satisfaction of medical staff were compared between the two groups. Results:The wearing time of mouth guard was 11.63±0.84 seconds and the removal time was 5.33±0.76 seconds in the observation group ( n=40), which were lower than those in the control group ( n=47) (14.91±1.21 seconds, t=-14.463, P<0.001; 10.38±0.80 seconds, t=-30.095, P<0.001). The wearing satisfaction score was 9.80±0.61, the lowest SpO 2 was (96.70±3.42)%, the removal satisfaction score was 9.75±0.67, and the anesthesiologists' satisfaction score was 9.20±1.42 in the observation group, which were higher than those in the control group [7.70±0.93, t=12.209, P<0.001; (94.06±3.72)%, t=3.417, P=0.001; 7.96±0.98, t=9.803, P<0.001; 8.13±1.35, t=3.615, P=0.001] with significant difference. There was no significant difference in the incidence of hypoxemia [10.00% (4/40) VS 14.89% (7/47), χ2=0.130, P=0.718] and endoscopic physician satisfaction score (9.30±0.97 VS 9.02±1.31, t=1.112, P=0.269) between the two groups. Conclusion:The oral-nasal oxygen supply mouth guard is easy to wear and remove, effectively reducing SpO 2 fluctuations during painless gastroscopy for snoring patients. It can enhance medical staff satisfaction with high clinical value.

Ensuring food safety is paramount worldwide.Developing effective detection methods to ensure food safety can be challenging owing to trace hazards,long detection time,and resource-poor sites,in addition to the matrix effects of food.Personal glucose meter(PGM),a classic point-of-care testing device,possesses unique application advantages,demonstrating promise in food safety.Currently,many studies have used PGM-based biosensors and signal amplification technologies to achieve sensitive and specific detection of food hazards.Signal amplification technologies have the potential to greatly improve the analytical performance and integration of PGMs with biosensors,which is crucial for solving the challenges associated with the use of PGMs for food safety analysis.This review introduces the basic detection principle of a PGM-based sensing strategy,which consists of three key factors:target recog-nition,signal transduction,and signal output.Representative studies of existing PGM-based sensing strategies combined with various signal amplification technologies(nanomaterial-loaded multienzyme labeling,nucleic acid reaction,DNAzyme catalysis,responsive nanomaterial encapsulation,and others)in the field of food safety detection are reviewed.Future perspectives and potential opportunities and challenges associated with PGMs in the field of food safety are discussed.Despite the need for complex sample preparation and the lack of standardization in the field,using PGMs in combination with signal amplification technology shows promise as a rapid and cost-effective method for food safety hazard analysis.

Major depressive disorder (MDD) is characterized by emotion dysregulation. Whether implicit emotion regulation can compensate for this deficit remains unknown. In this study, we recruited 159 subjects who were healthy controls, had subclinical depression, or had MDD, and examined them under baseline, implicit, and explicit reappraisal conditions. Explicit reappraisal led to the most negative feelings and the largest parietal late positive potential (parietal LPP, an index of emotion intensity) in the MDD group compared to the other two groups; the group difference was absent under the other two conditions. MDD patients showed larger regulatory effects in the LPP during implicit than explicit reappraisal, whereas healthy controls showed a reversed pattern. Furthermore, the frontal P3, an index of voluntary cognitive control, showed larger amplitudes in explicit reappraisal compared to baseline in the healthy and subclinical groups, but not in the MDD group, while implicit reappraisal did not increase P3 across groups. These findings suggest that implicit reappraisal is beneficial for clinical depression.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

Objective:To explor the effects of mentalization-based family therapy (MBFT) on the emotions of anxiety and depression, reflective functions, and related brain regions of adolescents with depression.Methods:Thirty-two adolescent patients with depression were selected in Beijing Huilongguan Hospital.Among them, fifteen patients treated with conventional drugs were defined as the control group, the other seventeen patients served as the observation group.On the basis of routine drug treatment, patients in the observation group were treated with 1.5 h MBFT once a week, for a total of 3 months.Among them, 10 patients underwent resting functional magnetic resonance imaging(rs-fMRI) scans before and after the intervention.SPSS 23.0 was used for statistical analysis of scale evaluation data by using chi-square test and repeated-measure analysis of variance, and pairwise Pearson correlation was used to construct a brain network matrix for the MRI results.The patient's brain network matrix was put into Gretna to calculate, and then use repeated measures analysis of variance and t test for judgment. Results:(1)Repeated measurement analysis of variance showed, over time and group, before and after intervention, the group×time interactions of patients' reflective function, anxiety, depression were statistically significant ( F=5.113, 9.350, 5.264, all P<0.05). Further simple effect analysis showed, in the observation group, there were statistically significant differences in patients' anxiety ((55.09±14.35) vs (30.58±3.62)), depression ((61.58±16.81) vs (31.00±3.48)) before and after intervention (all P<0.01). There was no significant difference in reflective function ((8.71±0.51) vs (8.87±0.50) ) in the observation group before and after intervention( P> 0.05). The reflective function((8.92±0.33) vs (8.73±0.35)) and anxiety((50.67±13.88) vs (45.78±12.89)) scores of the control group were not statistically significant different before and after intervention(all P>0.05), and the depression scores of the control group before and after inter-vention((69.33±9.11) vs (50.94±7.99)) were statistically significant different( P<0.01). (2)rs-fMRI showed that, using the posterior parietal lobe and the medial prefrontal lobe as seed points, the group×time interactions with right inferior frontal gyrus, right fusiform gyrus, right superior temporal gyrus, left middle temporal gyrus and right superior frontal gyrus were statistically significant ( F=29.56, 20.63, 8.69, 9.49, 8.62, all P<0.05). The further simple effect analysis showed in the observation group, the pre-test was less than the post-test, and the difference was statistically significant( P<0.05). In the control group, there were not statistically significant differences in the functional connection strength before and after the test(all P>0.05). (3)The brain network analysis of 264 regions of interest (ROIs) in the whole brain showed that the number of modules in the observation group was less than that in the control group, and the difference was statistically significant ( t=-2.64, P=0.046). Conclusion:MBFT can improve the anxiety and depression of adolescent patients with depression.It enhances the functional link between mentalization related brain regions and the whole brain, and enhances the activity of the whole brain link to become more integrated.

Objective:To investigate the efficacy of personalized family doctor contract services on risk factors of atherosclerotic cardiovascular disease (ASCVD) in high-risk population.Methods:Ten matched-community health centers of Shenzhen Luohu district were divided into intervention group and control group by cluster randomiztion. Subjects with high risks of ASCVD were screened out as intervention group from contracted residents who visited these centers and had complete data of the China-PAR model from August 2018 to April 2019. The control group received conventional general family doctor contract services. The individualized management were given to the intervention group after fully understanding patients′ ideas, concerns, and expectations (ICE). After 2-year intervention, score changes of ASCVD risk factors within and between groups were compared.Results:A total of 571 patients were enrolled, including 288 in the intervention group and 283 in the control group. After 2 years of intervention, 7 and 18 were lost to follow-up in two groups, respectively. Finally, 281 in the intervention group and 265 in the control group were included in the study. At baseline, there was no significant difference in ASCVD scores between the intervention group and the control group [(13.33±3.54) vs. (13.09±3.54) points; t=0.84, P=0.403], and the scores in both groups decreased significantly after the intervention [(10.89±4.01), (11.62±4.11) points], while the intervention group decreased more significantly (both P<0.05). Among the risk factors at baseline, HDL-C and diastolic blood pressure in the intervention group were lower than those in the control group, and there were no significant differences in other factors between the two groups. After the intervention, the levels of total cholesterol, systolic blood pressure and diastolic blood pressure in the two groups decreased significantly, and the number of people taking antihypertensive drugs increased significantly ( P<0.001 and P<0.05); HDL-C decreased in the control group ( P=0.023). After the intervention, compared to control group the intervention group had a higher proportion of patients taking antihypertensive drugs, with lower systolic and diastolic blood pressure ( P<0.05). After the intervention, the increase rate of HDL-C in the intervention group was more than that in the control group, and the decrease rate was less than that in the control group (χ 2=6.65, P=0.036). Conclusion:Family doctor contract services can reduce the risk factors of ASCVD, and personalized family doctor contract services can further improve the effects in the prevention and control of ASCVD. However, the effects might be insignificant and inconsistent for the ASCVD risk factors with deeper management requirements or no specific management measures, which highlights the complexity and diversity of ASCVD prevention and control, calling for multi-level and multi-faceted thinking and exploration.

【Objective】 To develop a new approach for the preparation of 0.7~0.8 hematocrit concentrated washed red blood cells(RBCs) for fetal anemia in utero transfusion and apply it in clinical. 【Methods】 The erythrocyte suspension and frozen stored erythrocytes within expiry date in Guangzhou Blood Center from March 2020 to February 2021 were taken to prepare concentrated washed RBCs. According to the derivation formula, corresponding weight of RBC preservation solution was added to obtain 0.7~0.8 hematocrit concentrated washed RBCs. Routine blood test data were statistically analyzed by single-sample t test, and P<0.05 was considered statistically significant.
