ObjectiveTo explore the coercive experience of involuntarily hospitalized adolescents with mental disorders during the admission process and hospitalization, providing references for formulating targeted nursing interventions. MethodsSemi-structured interviews were conducted with 15 involuntarily hospitalized adolescents with mental disorders selected from October to December 2023, and the themes were summarized and extracted by content analysis. ResultsA total of 3 themes and 10 sub-themes were extracted, which were used to elaborate the essential contents, causes, and improvement methods of coercive experience. These encompassed the multi-dimensional content of coercive experience (complex emotional experience, different physical sensations, and contradictory cognitive evaluation), the multi-faceted causes of coercive experience (insufficient personal preparation, inadequate parental communication, and strict medical management system), as well as the phased improvement of coercive experience (adequate communication before hospitalization, patient notification before coercive intervention, respecting for demands during coercive intervention, and comforting explanation after coercive intervention). ConclusionThe essential content of the coercive experience of involuntarily hospitalized adolescents with mental disorders is complex and has various causes, which require cooperation from multiple parties to improve. Therefore, parents should respect the expression of their children’s self-will, and medical staff should respect patients’ autonomy, establishing a protection-constrained doctor-patient relationship model and collaborating to reduce the use of coercive interventions, to improve the overall medical satisfaction of adolescents with mental disorders.

Stroke is the main cause of death and disability among adults in China and is characterized by high incidence, disability, mortality, and recurrence rates. The combination of traditional Chinese and Western medicine has great potential in treating stroke and its sequelae. The classic traditional Chinese medicine prescription Da Chengqitang (DCQT) has a long history and proven efficacy in treating stroke. Clinically, DCQT is often used to treat stroke and its sequelae. However, the number and quality of clinical trials of DCQT in treating stroke need to be improved. Because of the insufficient basic research, the active ingredients and multi-target mechanism of action of DCQT remain unclear. Our research group has previously confirmed that DCQT can effectively reverse neurological damage, reduce iron deposition, and downregulate the levels of pro-inflammatory cytokines in the rat model of hemorrhagic stroke. The treatment mechanism is related to the nuclear factor erythroid 2-related factor 2 (Nrf2)-mediated signaling pathway and p38 mitogen-activated protein kinase (MAPK) signaling-mediated microglia activation. To clarify the pharmacodynamic basis and anti-stroke mechanism of DCQT, this article reviews the research progress in the treatment of stroke with DCQT in terms of clinical trials, pharmacodynamic material basis, safety evaluation, and mechanisms of absorbed components. This article summarizes 45 major phytochemical components of DCQT, 11 of which are currently confirmed absorbed components. Among them, emodin, rhein, chrysophanol, aloe-emodin, synephrine, hesperidin, naringin, magnolol, and honokiol can be used as quality markers (Q-markers) of DCQT. The mechanism of DCQT in treating stroke is complex, involving regulation of inflammatory responses, neuronal damage, oxidative stress, blood-brain barrier, brain-derived neurotrophic factor, and anti-platelet aggregation. This article helps to deeply understand the pharmacodynamic basis and mechanism of DCQT in treating stroke and provides a theoretical basis for the clinical application of DCQT in treating stroke and the development of stroke drugs.

It is believed that the occurrence and development of squamous cell carcinoma (SCC) is closely associated with inflammatory responses. The theory of fire and heat, advocated by LIU Wansu, provides significant clinical guidance for understanding the pathogenesis and treatment of SCC. Based on this theory, the pathological mechanisms and clinical characteristics of SCC at different stages were analyzed. In the precancerous and early stages, the primary pathogenesis is qi stagnation leading to internal generation of constrained heat; in post-surgery, the condition shifts to qi deficiency with latent yin fire; during the treatment phase, the pathogenesis involves accumulation of pathogenic factors, excess toxins, and severe heat toxicity; in the late stage, the main pathology is yin deficiency with toxic heat, and phlegm-stasis obstruction of the internal organs. Corresponding stage-based treatment strategies are proposed. In the early stage, regulating qi movement to dissipate constrained heat; for post-surgery, tonifying qi and raising yang to dispel latent fire; during treatment stage, clearing heat and detoxifying to eliminate cancerous toxins; and in the late stage, nourishing yin and unblocking the bowels to clear deficiency heat.

Objective:
To investigate the role and mechanism of the heat-clearing and detoxifying drug Laggerae Herba in regulating the nuclear factor-erythroid 2-related factor-2(Nrf2)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) signaling pathway to inhibit ferroptosis and improve chronic heart failure induced by transverse aortic arch constriction in mice.
Methods:
Twenty-four male ICR mice were divided into the sham (n=6) and transverse aortic arch constriction groups (n=18) according to the random number table method. The transverse aortic arch constriction group underwent transverse aortic constriction surgery to establish models. After modeling, the transverse aortic arch constriction group was further divided into the model, captopril, and Laggerae Herba groups according to the random number table method, with six mice per group. The captopril (15 mg/kg) and Laggerae Herba groups (1.95 g/kg) received the corresponding drugs by gavage, whereas the sham operation and model groups were administered the same volume of ultrapure water by gavage once a day for four consecutive weeks. After treatment, the cardiac function indexes of mice in each group were detected using ultrasound. The heart mass and tibia length were measured to calculate the ratio of heart weight to tibia length. Hematoxylin and eosin staining were used to observe the pathological changes in myocardial tissue. Masson staining was used to observe the degree of myocardial fibrosis. Wheat germ agglutinin staining was used to observe the degree of myocardial cell hypertrophy. Prussian blue staining was used to observe the iron deposition in myocardial tissue. An enzyme-linked immunosorbent assay was used to detect the amino-terminal pro-brain natriuretic peptide (NT-proBNP) and glutathione (GSH) contents in mice serum. Colorimetry was used to detect the malondialdehyde (MDA) content in mice serum. Western blotting was used to detect the Nrf2, GPX4, SLC7A11, and ferritin heavy chain 1 (FTH1) protein expressions in mice cardiac tissue.
Results:
Compared with the sham group, in the model group, the ejection fraction (EF) and fractional shortening (FS) of mice decreased, the left ventricular end-systolic volume (LVESV) and left ventricular end-systolic diameter (LVESD) increased, the left ventricular anterior wall end-systolic thickness (LVAWs) and left ventricular posterior wall end-systolic thickness (LVPWs) decreased, the ratio of heart weight to tibia length increased, the myocardial tissue morphology changed, myocardial fibrosis increased, the cross-sectional area of myocardial cells increased, iron deposition appeared in myocardial tissue, the serum NT-proBNP and MDA levels increased, the GSH level decreased, and Nrf2, GPX4, SLC7A11, and FTH1 protein expressions in cardiac tissue decreased (P<0.05). Compared with the model group, in the captopril and Laggerae Herba groups, the EF, FS, and LVAWs increased, the LVESV and LVESD decreased, the ratio of heart weight to tibia length decreased, the myocardial cells were arranged neatly, the degree of myocardial fibrosis decreased, the cross-sectional area of myocardial cells decreased, the serum NT-proBNP level decreased, and the GSH level increased. Compared with the model group, the LVPWs increased, the iron deposition in myocardial tissue decreased, the serum MDA level decreased, and Nrf2, GPX4, SLC7A11, and FTH1 protein expressions in cardiac tissue increased (P<0.05) in the Laggerae Herba group.
Conclusion
Laggerae Herba improves the cardiac function of mice with chronic heart failure caused by transverse aortic arch constriction, reduces the pathological remodeling of the heart, and reduces fibrosis. Its mechanism may be related to Nrf2/SLC7A11/GPX4 pathway-mediated ferroptosis.

ObjectiveTo explore the spatial distribution patterns of flavonoid glycosides in Epimedium sagittatum and the influences of environmental factors on the accumulation of these components. MethodsThe spatial statistical analysis and GeoDetector model were used to analyze the distribution patterns of epimedin A,epimedin B,epimedin C,icariin,and total flavonoid glycosides in E. sagittatum samples from 92 different production areas in 36 cities of 13 provinces/municipalities/autonomous regions of China,as well as the effects of 28 environmental factors on the accumulation of each component. ResultsThe average content of flavonoid glycosides 64 (69.56%) producing areas and 30 (83.33%) cities met the quality standard of no less than 1.50% of total flavonoid glycosides in the 2020 edition of Chinese Pharmacopoeia.Epimedin A,epimedin B,epimedin C,icariin,and their sum showed significantly high accumulation.The hot spots regions of epimedin A and epimedin B were similar with each other,mainly located in western Hunan,eastern Hubei,eastern Guizhou,and northern Guangxi.The common hot spot areas of epimedin C and total flavonoid glycosides were in western and southwestern Hunan,southern Henan,northern Anhui,eastern Guizhou,and southern Chongqing.The hot spots areas of icariin were in southern Chongqing,western Hunan,and eastern and northeastern Guizhou.The interactions between environmental factors had stronger explanatory power for the accumulation of components than single factors.The strongest single factor and interactive factor affecting the accumulation of epimedin C were precipitation of wettest quarter (q=0.16) and its interaction with temperature seasonality (q=0.35),respectively.The strongest single factor influencing both the accumulation of icariin and total flavonoid glycosides was the precipitation of coldest quarter (q equals 0.15 and 0.22,respectively).The strongest interactions were observed between precipitation of coldest quarter and gravel content (q=0.34),as well as between precipitation of coldest quarter and aspect (q=0.35). ConclusionThirteen cities,including Zhumadian and Nanyang in Henan,Huaihua,Shaoyang,and Zhangjiajie in Hunan,and Zunyi,Qiandongnan,and Tongren in Guizhou,were hot spots of total flavonoid glycosides in E.sagittatum.Precipitation,gravel content,temperature seasonality,and aspect significantly influence the accumulation of flavonoid glycosides in E.sagittatum.This study provides reference for the utilization and production zoning of E.sagittatum.

Gastric cancer (GC) has an insidious onset and is mostly diagnosed in the middle and late stages after clinical detection. It is one of the malignant tumors with high incidence and mortality rates in the world. At present, the treatment plans are optimized mainly in terms of surgery, radiotherapy, and intervention, while the endpoints of clinical trials, such as patients' overall survival, progression-free survival, and disease-free survival, are still unsatisfactory. Therefore, effectively delaying the dynamic inflammation-cancer transformation has become an urgent bottleneck in the prevention and treatment of GC. In 1920s, Professor Otto Warburg discovered the phenomenon that tumor cells can accelerate glycolysis. Since then, the abnormal metabolic network inside tumor cells has gradually entered into researchers' view, and the hot academic research topic of metabolic reprogramming has been proposed. Tumor cells can meet their own energy consumption and adapt to external changes by adjusting their metabolic pathways to achieve rapid proliferation. In recent years, traditional Chinese medicine (TCM) is resolutely pursuing innovation in inheritance and the continuous refinement of research has led to the precision-oriented transition of TCM theories. Therefore, linking TCM with the treatment of tumors and precancerous diseases has certain research connotations. The searching and review of the publications in this field revealed that the number of publications in tumor-related metabolism increased dramatically, while there were only a few studies using TCM as a therapeutic solution. The research group has long been committed to the study of precancerous lesions of gastric cancer (PLGC) in Chinese and Western medicine. This article explained the dynamic process of inflammation-cancer transformation from the perspective of spleen deficiency-Qi stagnation-collateral stasis. The molecules of hypoxia-inducible factor (HIF)-1α, cancer-Myc (c-Myc), apolipoprotein E (APOE) and pyruvate kinase M2 (PKM2) were selected to reflect the biological connotation of inflammation-cancer transformation. The current achievements of TCM in regulating the metabolic reprogramming to intervene in inflammation-cancer transformation were summarized, with a view to providing more information for TCM to intervene in the inflammation-cancer transformation of gastric mucosa.

To analyze the Non-duplicate CRAB strains isolated from clinical specimens between June and December 2023 at Huai'an First People's Hospital Affiliated to Nanjing Medical University were retrospectively collected. The minimum inhibitory concentrations of commonly used antimicrobial agents against these strains were determined using the broth microdilution method. A total of 48 CRAB strains were included. COL-based combination regimens all exhibited favorable synergistic or additive effects against CRAB. Among them, the COL+IPM group showed the highest synergistic rate (83.3%), while the COL+AMK and COL+CSL groups primarily demonstrated additive effects (additive rates of 66.7% and 70.8%, respectively). TGC-based combination regimens mainly exhibited additive or indifferent effects, with the TGC+CSL group showing the highest additive rate (75.0%) and the TGC+AMK group showing the highest indifferent rate (70.8%). No antagonistic effects were observed in any of the six combination regimens. Further analysis revealed that the antibacterial effect of the COL+IPM group against CRAB was significantly different from that of the other combination regimens ( The combination of COL and IPM demonstrates the optimal synergistic antibacterial effect against CRAB, with the highest synergistic rate, and can be used as an empirical combination regimen for the clinical treatment of CRAB infections.

To investigate the genetic relatedness between carbapenem-resistant A retrospective analysis was conducted on clinical data from patients screened for carbapenem-resistant Among 12 878 patients screened for CRE, 60 (0.47%) were identified with intestinal CRKP colonization. Of these, 6 (10.0%) developed bloodstream infections, with an all-cause mortality rate of 66.7% (4/6) during hospitalization. The predominant strain type among paired isolates was ST11-KL64 producing KPC-2, accounting for 91.7%(11/12) of cases. Except for one patient(with a categorical agreement of 82.6%), colonizing and bloodstream isolates from the same patient showed complete agreement (100% categorical agreement) in antimicrobial susceptibility profiles for all antibiotics except tigecycline. Intraclass correlation coefficients for biofilm formation and siderophore production were both > 0.75 of all paired strains, indicating high phenotypic consistency. Except for one patient, core genome single nucleotide polymorphism (SNP) analysis and phylogenetic reconstruction revealed high genetic homology between colonizing and bloodstream isolates from the same patient (SNP difference < 10). Clonal relatedness was also observed among colonizing strains from different departments (SNP difference < 120). Although the intestinal colonization rate of CRKP is low, it poses a high mortality risk once bloodstream infection occurs. The high consistency in antimicrobial resistance profiles, biofilm formation, siderophore production, and genomic homology between colonizing and bloodstream isolates suggests that intestinal colonization is the direct source of subsequent invasive infection. Enhanced early screening, dynamic monitoring, risk-stratified prevention, and optimized intervention strategies are recommended to reduce the risk of CRKP infection and mortality.

Objective:
This study aimed to construct an animal model of heart failure with preserved ejection fraction (HFpEF) that integrates disease and syndrome based on the "deficiency-blood stasis-toxin" pathogenesis and to evaluate it comprehensively.
Methods:
The HFpEF mouse model was constructed using a combination of Nω-nitro-L-arginine methyl ester (L-NAME) and a high-fat diet. According to the random number table method, SPF-grade male C57BL/6J mice were randomly assigned to the control, L-NAME, high-fat diet, and model groups, 10 in each group. Comprehensive observations and data collection on macroscopic signs (e.g., fur condition, mental state, stool and urine, oral and nasal condition, paw and body condition, etc.) and cardiac function were performed after 10 and 16 weeks of model induction. Additionally, the syndrome evolution was elucidated based on diagnostic criteria for clinical syndromes of heart failure. Furthermore, pathological and molecular biological examinations of myocardial tissue were performed to assess the stability and reliability of the model.
Results:
Mice in the model group showed typical characteristics of syndrome of qi deficiency and blood stasis, as well as syndrome of internal heat accumulation, including lethargy, slow response, dull paw color and oral/nasal color, exercise intolerance, abnormal platelet activation, dry feces, and dark yellow urine. The time window for these syndromes was between 10 and 16 weeks post-modeling. Cardiac function assessments revealed severe diastolic dysfunction, concentric myocardial hypertrophy, and myocardial fibrosis in the model group. Pathological examinations showed a significantly increased collagen deposition in the myocardial interstitium, enlarged cross-sectional area of cardiomyocytes, and sparse coronary microvasculature in the model group. Molecular biological analyses indicated marked activation of the inducible nitric oxide synthase/nuclear factor kappa-light-chain-enhancer of activated B cells/NOD-like receptor family pyrin domain containing 3 inflammatory pathway and significantly elevated inflammation levels in the myocardial tissue of the model group. Although mice in the L-NAME and high-fat diet groups also showed certain manifestations of qi deficiency syndrome, the substantial cardiac damage was relatively limited compared to the control group.
Conclusion
This study has constructed an animal model of HFpEF that integrates disease and syndrome based on the "deficiency-blood stasis-toxin" pathogenesis. The macroscopic and microscopic characteristics of this model are consistent with the manifestations of syndrome of qi deficiency and blood stasis, toxin syndrome, and syndrome of internal heat accumulation. Moreover, it can stably simulate the HFpEF state and reflect phenotypic changes in human disease. This model provides a suitable experimental platform to explore the pathogenesis of HFpEF, evaluate the effectiveness of traditional Chinese medicine (TCM) treatment regimens, and promote in-depth research on TCM syndromes of heart failure.
