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 feasibility of selectively omitting ureteral stent placement after ureteroscopic lithotripsy(URL).Methods A total of 118 patients with distal ureteral calculi undergoing URL from 2021 to 2024 were enrolled.Patients were divided into a control group(indwelling ureteral stent for 2 weeks,n=86)and an observation group(no ureteral stent placement,n=32).General data,operation time,hospital stay,and total medical costs were compared between the two groups.Patients were followed 2 weeks postoperatively for assessment of flank pain visual analogue scale(VAS)scores,bladder irritation symptoms,hematuria,and incidence of urinary tract infection.Hydronephrosis was evaluated by ultrasonography 3 months after surgery.Results There was no significant difference in the general information and operation time between the two groups(P>0.05).The length of hospital stay and total treatment cost in the observa-tion group were significantly lower than those in the control group(P<0.05).Two weeks after surgery,the VAS scores of low back pain on the affected side and occurrence rates of bladder irritation symptoms,hematu-ria,and urinary tract infection in the observation group were significantly lower than those in the control group(P<0.01).Three months after operation,no hydronephrosis was observed in both groups.Conclusion It is safe and feasible to avoid indwelling ureteral stent after URL in appropriate cases.

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.

Neoadjuvant chemoradiotherapy or chemotherapy combined with surgery for locally advanced esophageal cancer has become the standard treatment, and despite the survival benefit, most patients still experience postoperative recurrence and distant metastasis. Immune checkpoint inhibitors play an anti-tumor role by activating T cells, and immunotherapy has become one of the important strategies for first-line and second-line treatment of advanced esophageal cancer with the continuous evolution of immunotherapy models. Regarding neoadjuvant immunotherapy for esophageal cancer, a large number of studies are being carried out and explored, which are expected to inject new vitality into neoadjuvant therapy for esophageal cancer. This article reviews the current clinical studies on neoadjuvant immunotherapy for esophageal cancer.

The outer membrane composed predominantly of lipopolysaccharide (LPS) is an essential biological barrier for most Gram-negative (G^-) bacteria. Lipopolysaccharide transport protein (Lpt) complex LptDE is responsible for the critical final stage of LPS transport and outer membrane assembly. The structure and function of LptDE are highly conserved in most G^- bacteria but absent in mammalian cells, and thus LptDE complex is regarded as an attractive antibacterial target. In recent 10 years, the deciphering of the three-dimensional structure of LptDE protein facilities the drug discovery based on such "non-enzyme" proteins. Murepavadin, a peptidomimetic compound, was reported to be the first compound able to target LptD, enlightening a new class of antibacterial molecules with novel mechanisms of action. This article is devoted to summarize the molecular characteristics, structure-function of LptDE protein complex and review the development of murepavadin and related peptidomimetic compounds, in order to provide references for relevant researches.

Objective:To analyze the level and clinical significance of IL-18 and IL-18-binding protein (BP) in the bone marrow of patients with myelodysplastic syndrome (MDS) .Methods:A total of 43 newly diagnosed patients with MDS who were admitted to the Department of Hematology, Tianjin Medical University General Hospital, from July 2020 to February 2021 were randomly selected. The control group consisted of 14 patients with acute myeloid leukemia (AML) and 25 patients with iron-deficiency anemia (IDA). The levels of IL-18 and IL-18 BP in the bone marrow supernatant were measured, and their correlations with MDS severity, as well as the functionality of CD8 + T cells and natural killer cells, was analyzed. Results:The levels of IL-18, IL-18 BP, and free IL-18 (fIL-18) in the bone marrow supernatant of patients with MDS were higher than in the IDA group. The level of fIL-18 was linearly and negatively correlated with the MDS-International Prognostic Scoring System (IPSS) score. IL-18 receptor (IL-18Rα) expression on CD8 + T cells in the MDS group was lower than in the IDA group, and the levels of fIL-18 and IL-18Rα were positively correlated with CD8 + T-cell function in the MDS group. Conclusion:IL-18 BP antagonizes IL-18, leading to a decrease in fIL-18 in the bone marrow microenvironment of patients with MDS, affecting CD8 + T-cell function, which is closely related to MDS severity; therefore, it may become a new target for MDS treatment.

Objective To compare the differences in dosimetric parameters between gradient optimization(GO)method and dynamic multi leaf collimator automatic optimization(dMLC-AO)method in craniospinal irradiation(CSI)to provide references for enhancing the feasibility of CSI planning of Monaco treatment planning system.Methods Fifteen patients undergoing CSI at some hospital were retrospectively selected,and a GO plan(enrolled into a GO group)and a dMLC-AO plan(enrolled into a dMLC-AO group)were designed for volumetric modulated arc therapy for each patient by the Monaco treatment planning system.The two groups were compared in terms of the dosimetric parameters of the planning target volume,dose transition zone and organ at risk.SPSS 24.0 statistical software was used for data analysis.Results The dMLC-AO group behaved slightly better than the GO group in D98％ and homogeneity index,with the differences being significant(P＜0.05),while the two groups were not different statistically in D2％,D50％and conformity index(P＞0.05).There were no significant differences between the two groups in radiation doses to the organs at risk except intestinal Dmean(P＞0.05).The GO group gained advantages over the dMLC-AO group in dose distribution conformity at the drop zone,and the target volume length covered by the 36 Gy isodose line for the intermdediate-section plan of the GO group was significantly longer than that of the dMLC-AO group.Conclusion GO method behaves better than dMLC-AO method in controlling effectively the dose drop at the dose transition zone of CSI plan.[Chinese Medical Equipment Journal,2024,45(9):62-66]

Mitochondrial diabetes mellitus (MDM) is a genetically heterogeneous disorder caused by mitochondrial DNA (mtDNA) or nuclear DNA mutations, characterized by multi-system involvement and diverse clinical phenotypes. We report a pediatric case presenting with growth retardation followed by subsequent development of diabetes mellitus. Systematic evaluation revealed concurrent bilateral sensorineural hearing loss, bilateral basal ganglia calcification, and electroencephalographic abnormalities. A post-exercise lactate test demonstrated significant elevation of serum lactate levels immediately after physical exertion. Genetic analysis identified a large-scale mitochondrial DNA deletion spanning from m.8649 to m.16084. This case report is complemented by a literature review focusing on the pathogenesis, genetic characteristics, and therapeutic approaches of mitochondrial diabetes, with particular emphasis on mitochondrial disorders exhibiting large-scale mtDNA deletions alongside diabetic manifestations. Our comprehensive analysis aims to enhance clinical understanding and inform diagnostic strategies for this complex disease entity.
