ObjectiveTo evaluate the detection specificity for clinical samples and the detection capability for standard substances of five commercially available multiplex polymerase chain reaction (PCR) nucleic acid detection kits (hereinafter referred to as the kits) for respiratory pathogens, and to provide a reference for selecting appropriate detection kits for multi-pathogen nucleic acid testing of respiratory infections. MethodsA total of 60 respiratory pathogen-positive clinical samples with known redults were selected and tested using the five kits (labeled as A, B, C, D, and E). The detection rates and Kappa coefficients were calculated to evaluate the consistency between the results from these kits and those from single-pathogen PCR kits. According to the limit of detection (LOD) provided by the kits, standard substances of respiratory pathogens (including 12 types such as influenza virus, Mycoplasma pneumoniae, and Bordetella pertussis) were diluted to four concentrations (250, 500, 1 000, and 2 000 copies·mL⁻¹). All five kits were used for detection to evaluate their respective detection capabilities. ResultsCompared with the results from single-pathogen PCR kits, the five tested kits demonstrated good consistency (all Kappa >0.80). Among them, Kit A had the highest detection rate (100.00%), followed by Kits C and E (98.33%), and then Kits B and D (95.00%). All five kits showed a relatively low false negative rate (FNR) for samples with a cycle threshold (Ct) value ≤35 (≤2.38%). However, for samples with Ct values>35, the FNR increased accordingly(average FNR=6.67%, P=0.029). Kit C exhibited the highest detection sensitivity for the tested standard substances (average LOD: 458.33 copies·mL⁻¹), followed by Kit D, then Kits A/E, and finally Kit B. ConclusionThe five multiplex PCR kits showed good consistency with single-pathogen detection results, but each had its own performance emphasis. Kit A, with the highest detection rate and high throughput, is suitable for targeted viral screening. Kit B, covering the broadest pathogen spectrum (including fungi/bacteria), is suitable for comprehensive respiratory pathogen screening. Kits C, D and E, are applicable for rapid detection. It is important to note that the detection efficacy of all kits decreases for low viral load samples with Ct values >35. In practical application, selection should be based on specific screening objectives, throughput requirements, and sample types.

The multimorbidity of rheumatoid arthritis (RA) and periodontitis (PD) has drawn increasing attention, as both conditions are characterized by chronic inflammation, immune dysregulation, and progressive bone destruction. Modern research confirms that PD is a significant risk factor for RA development, and their coexistence mutually exacerbates disease progression. However, traditional Chinese medicine (TCM) currently lacks a systematic theoretical explanation for this complex multimorbid relationship. This study, based on the TCM theory of abnormal collateral, thoroughly examines the intrinsic connection between RA and PD multimorbidity, proposing "abnormal collateral as the pivot, with accumulated toxins eroding bone" as the core TCM pathogenesis. The research elucidates PD as the "origin of abnormal collateral", where its pathogens act as toxic factors that invade the joints through collaterals, triggering RA via mechanisms such as molecular mimicry. The dynamic pathological progression of RA-PD multimorbidity can be described as follows: the displacement of Ying and Wei at the microscopic level manifests as immune hyperactivation, leading to collateral malnutrition; heat-toxins traversing collaterals induce collateral hyperactivity, resulting in pathological angiogenesis; ultimately, toxin accumulation at the pivotal abnormal collateral site erodes bone, activating the receptor activator of nuclear factor kappa-B ligand (RANKL)-receptor activator of nuclear factor kappa-B (RANK) signaling pathway-driven osteoclast differentiation. This theoretical framework innovatively integrates modern findings in oral microbiology, immune-inflammation, and bone metabolism, offering a holistic and dynamic perspective to understand the complexity of multimorbidity. Given the limited efficacy of current periodontal treatments for RA and the scarcity of reported TCM compound interventions for multimorbidity, the abnormal collateral theory proposes a systematic intervention strategy centered on "governing diseases through collaterals and regulating collaterals with herbs", along with TCM therapeutic principles such as "unblocking, clearing, and nourishing collaterals". Potential herbal treatments for multimorbidity are also highlighted. Future research should focus on refining TCM syndrome patterns in multimorbid patients and leveraging omics technologies for deeper exploration, thereby providing a theoretical foundation and research direction for TCM in addressing complex multimorbid conditions.

Bronchial asthma (BA) is a common chronic inflammatory airway disease characterized by airway hyperresponsiveness and reversible airflow limitation. Lung macrophages (LMs), as important effector cells of the innate immune system, play an important role in recognizing and engulfing pathogens, clearing harmful particles, and regulating immune responses. LMs can be polarized to M1 (pro-inflammatory) or M2 (anti-inflammatory) in different immune environments and participate in promoting or inhibiting inflammatory response, as well as lung parenchyma injury and repair (airway remodeling), playing a key role in the BA occurrence and development. Regulating the polarization balance of macrophages can not only inhibit the inflammatory response in the airway and reduce airway hyperresponsiveness, but also improve airway remodeling and immune regulation, reduce airway mucus secretion, and alleviate the clinical BA symptoms. Traditional Chinese medicine and its active ingredients, especially polysaccharides and saponins, can regulate the polarization balance of M1/M2 macrophages. Traditional Chinese medicine compounds can balance the secretion of anti-inflammatory and pro-inflammatory factors by staging treatment and targeting the polarization state of M1/M2 macrophages, inhibit inflammatory response in the airway, reduce airway remodeling, and improve the BA symptoms. This paper summarized the research progress on the regulation of M1/M2 macrophage polarization by traditional Chinese medicine and its active ingredients, aiming to provide scientific evidence for the precise targeted therapy of BA.

OBJECTIVE To investigate the application and influencing factors of sodium-dependent glucose transporters 2 inhibitors(SGLT-2i) in patients with heart failure with preserved ejection fraction(HFpEF) in the real world. METHODS Data from 358 patients with HFpEF who were hospitalized at the First Affiliated Hospital of Chongqing Medical University from May 2023 to May 2024 were retrospectively collected. The patients were divided into the SGLT-2i group and the non-SGLT-2i group based on whether they were prescribed SGLT-2i upon discharge. Baseline characteristics, comorbidities, and differences in drug treatment were compared between the two groups. Based on univariate analysis, multivariate Logistic regression analysis was performed to identify independent influencing factors of SGLT-2i use in patients with HFpEF, followed by further stratified analysis. RESULTS Among 358 HFpEF patients, the overall utilization rate of SGLT-2i was 33.5%. Combined with type 2 diabetes [OR=9.063,95%CI(4.924-16.679) ] , atrial fibrillation [OR=3.135,95%CI(1.590-6.178) ] , coronary artery heart disease [OR=1.888,95%CI(1.072-3.327) ] and the use of loop diuretics [OR=3.822, 95%CI (1.588-9.200) ] were all independent influencing factors for the use of SGLT-2i in patients with HFpEF ( P <0.05). The results of the stratified descriptive analysis were consistent with those of the multivariate analysis, showing a higher utilization rate of SGLT-2i among patients with concomitant T2DM,atrial fibrillation, coronary artery heart disease, and those receiving loop diuretics ( P <0.05); whereas the utilization rate of SGLT-2i was comparable across patients with different levels of renal function ( P >0.05). CONCLUSIONS In the real-world clinical practice, the utilization of SGLT-2i in patients with HFpEF remains suboptimal, and treatment coverage still needs to be improved. Their use of SGLT-2i is primarily influenced by the presence of type 2 diabetes, atrial fibrillation, coronary artery heart disease, and the use of loop diuretics.

Guishenwan (GSW), originating from Jingyue Quanshu (Zhang Jingyue's Complete Works), is a classic traditional Chinese medicine (TCM) formula with a history of over 400 years. Designed for kidney essence deficiency syndrome, it is clinically applied to treat diseases associated with essence-blood deficiency, such as ovarian insufficiency diseases in women, oligospermia-induced infertility in men, and lumbar disc herniation. Numerous studies have confirmed its significant efficacy and advantages in managing ovarian insufficiency diseases, including diminished ovarian reserve (DOR), premature ovarian insufficiency (POI), and premature ovarian failure (POF). According to recent literature, the therapeutic mechanisms of GSW in treating ovarian insufficiency diseases involve regulating the hypothalamic-pituitary-ovarian axis (HPOA) function, ameliorating reproductive endocrine disorders, improving ovarian function, modulating relevant signaling pathways, and exerting immunoregulatory and anti-inflammatory effects. A review of GSW in clinical treatment revealed that clinical applications of GSW, particularly in combination with Western medicine, not only alleviate symptoms but also compensate for the limitations of hormone replacement therapy, thereby reducing recurrence, minimizing adverse reactions, and enhancing safety. This review aims to provide a scientific basis for the rational clinical use of GSW in ovarian insufficiency diseases, offer innovative TCM strategies for developing novel ovarian-protective drugs, promote the integration of TCM and Western medicine in reproductive medicine, and ultimately contribute a Chinese approach to global management of ovarian insufficiency diseases.

Macular hole is an age-related disorder defined by a full-thickness defect of the foveal retina and a profound loss of central vision. First described in the mid-19th century, its study has now extended across more than 150 years. Breakthroughs in science and technology—especially the relentless refinement of retinal imaging platforms—have progressively refined our understanding of the disease. Optical coherence tomography(OCT)in particular has revolutionized characterization of the condition. At the same time, the widespread adoption of macular hole surgery has not only driven deeper investigations into pathogenesis and pre-operative assessment but also facilitated the global dissemination of surgical expertise and a marked rise in anatomical success. This review synthesizes the multimodal imaging hallmarks of macular holes and highlights the remaining clinical challenges in the application of OCT technology.

ObjectiveTo explore the efficacy and mechanisms of Sini San in the treatment of depression and liver injury based on gut microbiota. MethodsThirty-two male Sprague-Dawley (SD) rats were randomly divided into a normal group, model group (M), Sini San group (MS, 2.5 g·kg-1), and fluoxetine group (MF, 2 mg·kg-1). Except for the normal group, rats in the other three groups were subjected to chronic unpredictable mild stress (CUMS). After 8 weeks, the open-field test and sucrose preference test were conducted. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum corticosterone (CORT), adrenocorticotropic hormone (ACTH), corticotropin-releasing factor (CRF), lipopolysaccharide (LPS), Zonulin, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), γ-aminobutyric acid (GABA) levels in the hippocampus and prefrontal cortex, and brain-derived neurotrophic factor (BDNF) levels in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect hippocampal BDNF mRNA expression. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured using the ultraviolet lactate dehydrogenase method. The ultrastructure of the intestinal epithelium was observed by electron microscopy, and gut microbiota in rat feces were analyzed using 16S rDNA high-throughput sequencing. ResultsCompared with the normal group, the sucrose preference of rats in the model group was significantly reduced (P0.01), whereas it was significantly increased in the Sini San group compared with the model group (P0.05). Compared with the normal group, hippocampal GABA protein levels and BDNF mRNA expression in the model group were significantly decreased (P0.05), and compared with the model group, both were significantly increased in the Sini San group (P0.05, P0.01). Compared with the normal group, serum LPS and Zonulin levels in the model group were significantly increased (P0.05, P0.01), and compared with the model group, Zonulin levels in the Sini San group were significantly decreased (P0.05). No obvious changes were observed in the ultrastructure of the jejunal mucosa among groups. Compared with the normal group, widened and blurred tight junctions, sparse and shortened microvilli, and mitochondrial swelling with cristae disruption in epithelial cells were observed in the ileal and colonic mucosa of the model group, which were markedly improved in the Sini San and fluoxetine groups. The results of 16S rDNA high-throughput sequencing showed that Sini San improved CUMS-induced dysbiosis of Bacteroidetes and Proteobacteria. Correlation analysis indicated that Bacteroidetes and Proteobacteria were significantly correlated with depression-related indicators, liver function, and intestinal mucosal permeability. ConclusionSini San exerts antidepressant and hepatoprotective effects by improving Bacteroidetes and Proteobacteria and inhibiting the increase in intestinal mucosal permeability in CUMS rats.
