ObjectiveTo analyze the epidemiological characteristics of latent tuberculosis infection (LTBI) among newly detained populations in eastern China, to identify high-risk groups, and to provide a scientific basis for formulating tuberculosis prevention and control strategies in the prison system. MethodsA cross-sectional study was conducted among the newly admitted detainees in two prisons in eastern China in 2022. Data on demographic characteristics, behavioral risk factors and previous disease history of the research subjects were collected through a structured questionnaire survey. The LTBI status of the detainees was determined using the QuantiFERON-TB Gold In-Tube (QFT-GIT) method. Lasso regression was used to screen variables, followed by multivariate logistic regression analysis to investigate the influencing factors of LTBI. ResultsA total of 305 detainees were included in the study. The median age of detainees was 35 (31, 43) years. The study population was predominantly male (67.21%), of Han ethnicity (95.41%), had a junior or senior high school education (59.34%), and was unemployed (31.80%). A history of smoking was reported by 52.79% of participants, while 57.70% reported no alcohol consumption. The majority had no history of hypertension (85.90%), diabetes mellitus (93.77%), human immunodeficiency virus (HIV) infection (97.38%), familial genetic diseases (95.08%), surgery or trauma (73.77%), drug use (92.79%), or hepatitis (93.77%). The LTBI rate was 14.75%. After comparing the demographic characteristics of LTBI and non-infected groups, it was found that smoking history (χ2=7.40, P=0.025), drug use history (χ2=5.49, P=0.019), and HIV infection (χ2=8.12, P=0.004) were statistically correlated with LTBI infection. The results of multivariate logistic regression analyses showed that smoking [adjusted odds ratio (aOR)=4.08, 95%CI: 1.60‒10.42, P=0.003], HIV infection (aOR=11.57, 95%CI: 2.50‒53.51, P=0.002) and drug use (aOR=3.04, 95%CI: 1.02‒9.09, P=0.046) were risk factors for LTBI. ConclusionThe LTBI rate among newly detainees in two prisons in eastern China is slightly lower than that among long-term detainees. Early screening and intervention should be implemented for newly detainees, with particular attention focused on high-risk groups such as those with a history of smoking, HIV infection, or drug use.

γδ T cells possess both innate and adaptive immune characteristics. Their antigen recognition is independent of major histocompatibility complex presentation, and they can directly recognize abnormal tumor metabolism, showing unique application potential in tumors with low immune infiltration. This paper systematically sorts out the biological characteristics and antitumor immune functions of γδ T cells, and mainly reviews the relevant mechanisms by which active ingredients of traditional Chinese medicine regulate γδ T cells to exert antitumor immune functions. Glycyrrhiza polysaccharide and Astragalus polysaccharide can enhance the antitumor immune function of γδ T cells by promoting the expression of various cytokines, regulating intestinal flora and alleviating immunosuppressive state. Quercetin and puerarin can strengthen γδ T cell-mediated tumor cell killing by regulating the proliferation of γδ T cells, the expression of cytotoxic effector molecules and related signaling pathways. Toosendanin can potentiate γδ T cell-induced tumor cell killing by down-regulating the expression of anti-apoptotic protein in tumor cells. Artesunate can boost γδ T cell-mediated antitumor immune responses by enhancing the effector function of γδ T cells and weakening tumor immune escape. Future research shall focus on exploring the synergistic effects and molecular mechanisms of the combined application of active ingredients of traditional Chinese medicine and γδ T cell immunotherapy, and identifying the key targets for γδ T cells to exert antitumor immune functions.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by airflow limitation, and its high morbidity and disability rates pose a severe challenge to global public health. Traditional Chinese medicine (TCM) has demonstrated definite efficacy and distinctive characteristics in the treatment of COPD. Based on the understanding of ancient and modern physicians regarding the etiology, pathogenesis, and stage-based syndrome differentiation of COPD, this article systematically elaborates on the etiology, pathogenesis, and clinical principles of syndrome differentiation and treatment of COPD. COPD is characterized by deficiency at root and excess in manifestation, with the coexistence of deficiency and excess. Qi deficiency is the fundamental pathogenesis underlying the occurrence and development of COPD and runs throughout the entire disease course. The disease begins with deficiency of lung qi and gradually affects the spleen and kidney, leading to the internal generation of dampness, phlegm, and blood stasis. Phlegm and blood stasis are not only pathological products but also deep-rooted causes of recurrent disease. Together with qi deficiency, they are mutually causal and form a vicious cycle. During the acute exacerbation stage of COPD, phlegm and blood stasis constitute the predominant underlying pathology and are often induced by invasion of pathogenic factors due to deficiency of healthy Qi. In addition, innovative understandings of the etiology and pathogenesis of COPD have emerged from the perspectives of collateral disease, latent pathogens, smoke toxins, and dysfunction of the Shaoyang pivot. During the stable stage, deficiency of Qi in the lung, spleen, and kidney predominates and is often accompanied by phlegm and blood stasis. In the clinical differentiation and treatment of COPD, treatment should be based on different disease stages and syndrome characteristics. During the acute exacerbation stage, eliminating pathogenic factors is the primary principle, with treatment determined according to syndrome differentiation. For wind-cold attacking the lung, the treatment is to ventilate the lung, disperse cold, and relieve cough. For phlegm-dampness accumulating in the lung, the treatment is to dry dampness, resolve phlegm, and direct qi downward. For phlegm-heat obstructing the lung, the treatment is to clear the lung, resolve phlegm, and relieve asthma. For phlegm and blood stasis obstructing the lung, the treatment is to eliminate phlegm, remove blood stasis, and relieve asthma. During the stable stage, reinforcing healthy Qi is the key principle. For lung-spleen qi deficiency, the treatment is to tonify the lung and strengthen the spleen, resolve phlegm, and direct Qi downward to relieve asthma. For deficiency of both lung and kidney, the treatment is to tonify the lung and benefit the kidney, resolve phlegm, promote Qi reception, and relieve asthma. When accompanied by phlegm and blood stasis, the treatment should focus on tonifying deficiency, resolving phlegm, and removing blood stasis. This article aims to systematically summarize the TCM etiology, pathogenesis, syndrome differentiation and treatment principles of COPD, as well as the current shortcomings in related research, in order to provide a reference for the clinical treatment of COPD with TCM, give full play to the advantages of TCM in the prevention and treatment of COPD, and optimize the whole-course management of COPD.

As the medical model shifts toward the “bio-psycho-social” paradigm, interprofessional collaboration has become a significant trend in the medical field. Medical social work, as a key role in interprofessional teams, still faces challenges related to localization, professionalization, and specialization in its practice within hospital settings. From the perspective of “translation,” which serves as a critical step in actor-network theory, this study explored the behavioral logic and interest interactions among actors in interprofessional collaboration, and analyzed and summarized effective service models of interprofessional collaboration to address service dilemmas, with a particular focus on the role of medical social workers. Based on the current status of peritoneal dialysis patient services at Hospital Z, this study selected various subjects of interprofessional collaboration as the research participants. A total of 19 network actors were interviewed using purposive random sampling and snowball sampling. Semi-structured interviews and non-participant observation were employed as research methods, with a particular focus on observing the operational process of interaction and translation mechanisms among interprofessional collaboration subjects. Thematic analysis was conducted, with coding performed using NVivo 14 software. From the translation perspective, the study analyzed the collaboration model of the interprofessional team in the treatment and rehabilitation process of peritoneal dialysis patients, highlighting the special role of medical social workers therein. The implementation of the collaborative model often encountered challenges related to professional boundaries, power boundaries, and institutional boundaries, which affected the translation process across the entire trajectory. Discussions were further conducted on dimensions such as optimizing the flow mechanisms of power and discourse, as well as forming supportive policies and formalized collaborative mechanisms.

To establish a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the determination of levomethorphan, dextromethorphan and its metabolite dextrorphan in hair and urine, hair samples were ground and extracted by ultrasonication using a methanol solution containing SKF525A as the internal standard, while urine samples were processed by protein precipitation with the internal standard diazepam-D5. An Astec® CHIROBIOTIC® V2 column (250 mm × 2.1 mm, 5 µm) was used with the mobile phase consisting of 10 mmol/L ammonium acetate containing 0.5‰ formic acid and methanol. Detection was performed using positive electrospray ionization in multiple reaction monitoring mode. The linearity for levomethorphan, dextromethorphan, and dextrorphan in hair samples was 0.1–10 ng/mg, the limits of detection (LOD) were 0.05 ng/mg, and the limits of quantification (LOQ) were 0.1 ng/mg. In urine samples, the linearity was 1–200 ng/mL, LOD was 0.5 ng/mL, and LOQ was 1 ng/mL. Method validation met the requirements for biological sample testing and can be applied to drug monitoring. In actual case samples from China, dextromethorphan and dextrorphan were detected, while levomethorphan was not observed.This method is simple, fast, and highly sensitive to be used for the qualitative and quantitative analysis of levomethorphan, dextromethorphan, and dextrorphan in hair and urine samples.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.
