OBJECTIVE To explore the main factors influencing the blood concentration of duloxetine， and provide a scientific basis for the individualized use of duloxetine. METHODS Retrospective analysis was conducted on 434 inpatients with depressive disorders at the First Hospital of Hebei Medical University， who were treated with duloxetine and underwent blood concentration monitoring between January 2022 and April 2024. The study examined the impact of various factors， including gender， age， body mass index （BMI）， gene phenotypes， combined medication， drug type （original/generic）， and genotyping results of gene single nucleotide polymorphism loci， on blood concentration and the concentration-to-dose （C/D） after dose adjustment. RESULTS The blood concentration of duloxetine was 76.65 （45.57， 130.31） ng/mL， and C/D was 0.96 （0.63， 1.60） ng·d/（mL·mg）. The blood concentration of duloxetine was positively correlated with the daily dose of administration （R2＝0.253 7， P＜0.001）. Blood concentration of duloxetine in 38.94% of patients exceeded the recommended range specified in the guidelines. Gender， age， BMI， combined use of CYP2D6 enzyme inhibitors， and CYP2D6 and CYP1A2 phenotypes had significant effects on C/D of duloxetine （P＜0.05）. CONCLUSIONS The patient’s age， gender， BMI， combined medication， and genetic phenotypes are closely related to the blood concentration of duloxetine.

Objective To investigate and analyze epidemiological characteristics of patients with mycoplasma pneumoniae pneumonia (MPP) from 2020 to 2023, and the risk factors for plastic bronchitis (PB), To provide data support for developing preventive measures. Methods The medical records of 2 257 patients with respiratory tract infection treated at Huai'an Hospital Affiliated to Xuzhou Medical University from 2020 to 2023 were collected. Count the number of MPP patients and analyze the MP detection rate. Multivariate logistic regression analysis and ROC curve was used to screen the risk factors for PB. Results A total of 858 cases were positive for MP antibodies, and the detection rate was 38.02%. There are statistically significant differences in MP detection rates among different genders, age groups, and years (P<0.05). Among the 286 patients diagnosed with MPP and undergoing bronchoscopy, 68 (23.78%) patients had PB. According to univariate and multivariate logistic regression analysis, small age, higher N%, D-D, LDH and AST levels were independent risk factors for PB (P<0.05). ROC curve analysis shows that age and combined detection are the most effective indicators for PB prediction, with areas under the curve of 0.998 and 0.961, respectively. Conclusion MP is the main pathogen of respiratory tract infections in the area from 2020 to 2023. Women and children are more susceptible to MP infection. Small age, high N%, DD, LDH and AST levels are independent risk factors for PB in patients with MPP. Targeted preventive measures should be taken for MP susceptible population, and close attention should be paid to PB related risk factors to prevent disease progression and the occurrence of PB.

Progressive pulmonary fibrosis (PPF) is a progressive and lethal condition with few effective treatment options. Improvements in quality of life for patients with PPF remain limited even while receiving treatment with approved antifibrotic drugs. Traditional Chinese medicine (TCM) has the potential to improve cough, dyspnea and fatigue symptoms of patients with PPF. TCM treatments are typically diverse and individualized, requiring urgent development of efficient and precise design strategies to identify effective treatment options. We designed an innovative Bayesian adaptive two-stage trial, hoping to provide new ideas for the rapid evaluation of the effectiveness of TCM in PPF. An open-label, two-stage, adaptive Bayesian randomized controlled trial will be conducted in China. Based on Bayesian methods, the trial will employ response-adaptive randomization to allocate patients to study groups based on data collected over the course of the trial. The adaptive Bayesian trial design will employ a Bayesian hierarchical model with "stopping" and "continuation" criteria once a predetermined posterior probability of superiority or futility and a decision threshold are reached. The trial can be implemented more efficiently by sharing the master protocol and organizational management mechanisms of the sub-trial we have implemented. The primary patient-reported outcome is a change in the Leicester Cough Questionnaire score, reflecting an improvement in cough-specific quality of life. The adaptive Bayesian trial design may be a promising method to facilitate the rapid clinical evaluation of TCM effectiveness for PPF, and will provide an example for how to evaluate TCM effectiveness in rare and refractory diseases. However, due to the complexity of the trial implementation, sufficient simulation analysis by professional statistical analysts is required to construct a Bayesian response-adaptive randomization procedure for timely response. Moreover, detailed standard operating procedures need to be developed to ensure the feasibility of the trial implementation.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

Objective To investigate the correlations of the expression levels of plasma long non-coding RNA plasmacytoma variant translocation 1 (LncRNA PVT1) and microRNA-143-3p (miR-143-3p) with disease activity and prognosis in patients with rheumatoid arthritis (RA). Methods A total of 129 RA patients admitted to our hospital from April 2021 to April 2023 were selected as disease group. According to the 28-joint disease activity scores (DAS28), the patients were divided into stable disease group (n=28), mildly active group (n=42), moderately active group (n=35), and severely active group (n=24). According to the prognosis of the patients after 6 months of treatment, they were divided into good prognosis group (n=88) and poor prognosis group (n=41), and 110 healthy people who underwent physical examinations in our hospital during the same period were included as control group. The expression levels of plasma LncRNA PVT1 and miR-143-3p were detected using quantitative real-time fluorescent polymerase chain reaction (qRT-PCR). The targeting relationship between LncRNA PVT1 and miR-143-3p was predicted using the Target Scan Human website. Multivariate Logistic regression analysis was conducted to explore the factors influencing the prognosis of RA patients. Receiver operating characteristic (ROC) curve was performed to assess the predictive value of plasma LncRNA PVT1 and miR-143-3p for the prognosis of RA patients. Results The plasma LncRNA PVT1 level in the disease group was higher than that in the control group, while the plasma miR-143-3p level was lower (P < 0.05). The plasma LncRNA PVT1 levels decreased sequentially in the severe activity, moderate activity, mild activity, and disease stable groups, while the plasma miR-143-3p levels increased sequentially (P < 0.05).The proportion of patients positive for human leukocyte antigen-DR4 (HLA-DR4), DAS28, and plasma LncRNA PVT1 expression level were higher in the poor prognosis group than in the good prognosis group, while the plasma miR-143-3p level was lower (P < 0.05). Plasma LncRNA PVT1, miR-143-3p expression, HLA-DR4 positivity, and DAS28 were factors influencing the prognosis of RA patients (P < 0.05). LncRNA PVT1 and miR-143-3p had targeted binding sites, and there was a negative correlation between them (P < 0.05). The area under the curve (AUC) for the combined prediction of plasma LncRNA PVT1 and miR-143-3p for prognosis of RA patients was 0.914, which was superior to the individual diagnosis of LncRNA PVT1 or miR-143-3p (Z=2.159, P=0.031; Z=2.108, P=0.035). The sensitivity and specificity of the combined diagnosis were 95.12% and 78.41%, respectively. Conclusion The plasma LncRNA PVT1 level gradually increases, while the plasma miR-143-3p level gradually decreases with increasing RA disease activity. The combined detection of the two biomarkers has high predictive value for the prognosis of RA patients.

Lipopolysaccharides (LPS) are major outer membrane components of Gram-negative bacteria. Unlike most Gram-negative bacteria, Acinetobacter baumannii can still survive and acquire polymyxin resistance after complete loss of LPS. Previous studies of LPS-deficient Acinetobacter baumannii mostly focused on LPS-deficient strains induced by polymyxin, whose background was complex and unstable. To investigate LPS loss-mediated polymyxin resistant-Acinetobacter baumannii, this study constructed a stable and clear background LPS-deficient strain by knocking out lpxC gene in Acinetobacter baumannii ATCC 19606 with CIRSPR/Cas9, and then studied the phenotypic changes of the lpxC-deficient strain including morphology, growth rate, antibiotic susceptibility, virulence, membrane permeability, and membrane potential. Animal experiments were approved by the Animal Care and Welfare Committee Institute of Medicinal Biotechnology, CAMS and PUMC (approval number: IMB-20240119D₉). The results indicated that the lpxC gene of Acinetobacter baumannii ATCC 19606 was successfully knocked out. After losing the lpxC, the strain underwent the morphological change from rod-shaped to spherical. Furthermore, it leads to reduced growth rate, enhanced membrane permeability, decreased membrane potential, lower virulence, and increased antibiotic susceptibility to β-lactams, quinolones, aminoglycosides, macrolides, glycopeptides. The lpxC deletion results in significant changes in membrane homeostasis and adaptability of Acinetobacter baumannii. Understanding the phenotypic changes of colistin-resistant Acinetobacter baumannii mediated by LPS loss is useful for exploring the resistance mechanism of Acinetobacter baumannii and developing new therapeutic strategies.

Objective:To investigate the value of myocardium scar area in predicting adverse cardiovascular events (MACEs) after coronary artery bypass grafting (CABG) in patients with ischemic cardiomyopathy (ICM).Methods:The first part of this study was a retrospective study. Patients diagnosed with ICM and undergoing CABG surgery at Beijing Anzhen Hospital, Capital Medical University from January 2017 to December 2022 were enrolled as the discovery cohort. All patients underwent cardiac magnetic resonance-late gadolinium enhancement (CMR-LGE) before surgery. According to the occurrence of postoperative MACEs, the patients were divided into MACEs group and MACEs-free group. Preoperative clinical and imaging data, intraoperative and postoperative data were collected and compared between the two groups. The primary endpoint was postoperative MACEs. Univariate and multifactor regression analyses were used to analyze the risk factors for MACEs. Receiver operating characteristic (ROC) curves were constructed to evaluate the predictive efficacy and optimal cut-off value of myocardial scar area for endpoint events. The second part of this study was a prospective study. Patients with ICM who received CABG at Beijing Anzhen Hospital, Capital Medical University from January 2023 to June 2023 were enrolled as a validation cohort, and were divided into MACEs group and MACEs-free group according to whether MACEs occurred after surgery. Preoperative clinical and imaging data, intraoperative and postoperative data were collected and compared between the two groups. Verify the reliability of the cut-off value obtained by ROC curve in the validation cohort.Results:A total of 120 patients with ICM (30 patients in MACEs group and 90 patients in MACEs-free group), aged (61.6±8.7) years, including 93 males, were included in the discovery cohort. A total of 22 ICM patients (5 patients in MACEs group and 17 patients in MACEs-free group), aged (59.5±8.2) years, including 18 males, were included in the validation cohort. Multivariate Cox regression showed that myocardial scar area ( HR=1.258, 95% CI 1.096-1.444, P=0.001) was an independent risk factor for the primary endpoint event. The area under ROC curve of myocardial scar area for predicting postoperative MACEs was 0.90 (95% CI 0.83-0.95), and myocardial scar area≥36.0% was the optimal cut-off value for predicting postoperative MACEs, and its sensitivity, specificity and accuracy were 96.7%, 72.2% and 78.3%, respectively. In the validation cohort, the sensitivity, specificity and accuracy of myocardial scar area in predicting postoperative MACEs in patients with ICM after CABG were 80.0%, 82.4% and 81.8%, respectively. Conclusion:Myocardial scar area is an independent risk factor for MACEs after CABG in patients with ICM, and myocardial scar area≥36.0% is the optimal cut-off value for predicting MACEs after CABG. Myocardial scar area can help to identify patients at high risk of surgery and provide a basis for risk stratification of patients.

Type 2 diabetes mellitus (T2DM) is a complex metabolic disorder characterized by chronic hyperglycemia, hyperlipidemia, and peripheral insulin resistance. Endoplasmic reticulum stress (ERS), a response to cellular stress, is activated across various tissues during the progression of T2DM, leading to disruptions in protein synthesis. Notably, epithelial and endocrine cells with hormone-secreting functions are particularly vulnerable to functional impairments induced by ERS. The gut-pancreas axis is essential for regulating metabolism and the progression of T2DM. Intestinal epithelial L cells, integral to the intestinal barrier, can secrete the glucagon-like peptide-1 (GLP-1). This hormone promotes insulin secretion from pancreatic β-cells and plays a critical role in glucose metabolism. Importantly, ERS plays a critical role in regulating glucolipid-induced dysfunction of gut-pancreas axis. For instance, ERS is involved in regulating the intestinal barrier and the secretion of GLP-1 as well as insulin. Therefore, ERS can be a potential target for T2DM treatment. In this paper, we review the regulatory roles of ERS in the gut-pancreas axis during the development of T2DM, and summarize the therapeutic drugs and strategies targeting ERS for T2DM treatment.
