Chronic mucocutaneous candidiasis (CMC) is an infectious phenotype characterized by recurrent or persistent infections caused by Candida species that affect the skin, nails, oral, and genital mucosae for a duration exceeding six months. Current research suggests that CMC is an immunodeficiency disease with a complex pathogenesis. Patients with CMC have various defects in nonspecific and/or specific immunity against Candida infection, resulting in the inability of patients to defend themselves against Candida infection. CMC can be stratified into primary CMC and secondary CMC based on etiology. Primary CMC is often associated with genetic mutations leading to immunodeficiencies in T helper cell 17 and interleukin-17, whereas secondary CMC is frequently linked to factors such as human immunodeficiency virus infection, diabetes mellitus, and immunosuppressive therapy. Primary CMC typically manifests as Candida infections, with distinct genetic mutations often correlating to varied concomitant symptoms. Secondary CMC may present with not only superficial mucosal Candida infections and manifestations of the underlying primary disease but also with invasive fungal infections. Diagnosing CMC requires an integration of medical history and clinical presentation, supplemented by the outcomes of auxiliary diagnostic procedures, including microscopic examination of fungal smear, fungal culture, immunological testing, and genetic sequencing and analysis. Furthermore, confirming primary CMC requires exclusion of the aforementioned secondary factors. At present, antifungal drugs such as triazoles, echinocandins, and polyenes are the main treatment for CMC. Moreover, immunotherapy with biologics such as Janus kinase (JAK) inhibitors provides more options for the clinical treatment of patients with CMC. Gene therapy also has potential clinical application value. In this review, we discuss the etiologies, pathogenesis, clinical manifestations, diagnosis, and treatments of CMC, aiming to provide a reference for the clinical diagnosis and treatment of CMC.

Objective To assess the risk of hearing loss caused by occupational noise exposure in workers in an automobile manufacturing plant in Tianjin, China, and to perform risk management. Methods Occupational health field investigation and noise exposure measurements were conducted from July to December 2023, and physical examination data were collected. ISO 1999:2013(E) Acoustics-Estimation of Noise-Induced Hearing Loss and WS/T 754-2016 “Guidelines for Risk Management of Occupational Disease Hazards Caused by Noise” were used to predict the risk of high-frequency hearing loss and occupational noise induced deafness for operational workers and make a risk classification. Results The noise intensity of each workshop was 79.4 to 95.5 dB(A), and the maximum noise intensity of welding and stamping exceeded the standard. The results of the assessment showed that the noise level remained unchanged, and the risk of HFHL and ONID in workers increased as the predicted age and length of service increased. It was predicted that after the age of 40, the maximum risk of hearing loss in welding workers would be high risk, and the risk of stamping workers would be at higher risk, suggesting that welding and stamping were the key control posts of noise hazards in the enterprise. The N50 prediction values of permanent hearing threshold displacement caused by potential noise at all frequencies for final assembly and painting workers were lower than the measured values. Conclusion The consequences of hearing loss for workers in the welding and stamping shop noise operations at this automobile manufacturing plant are relatively serious and require risk management.

ObjectiveTo investigate the potential mechanism of Renshen Yangrongtang in alleviating myelosuppression by regulating the expression of reactive oxygen species (ROS), myeloperoxidase (MPO), and neutrophil extracellular traps (NETs). MethodsK562 cells were divided into blank group, etoposide group (40 μmol·L-1), and etoposide+Renshen Yangrongtang freeze-dried powder groups with low-, medium-, and high-dose (2, 4, 8 g·L-1). Liquid chromatography-mass spectrometry (LC-MS) was used to determine the freeze-dried powder of Renshen Yangrongtang. Enzyme-Linked Immunosorbent Assay (ELISA) was used to detect ROS, MPO, and NETs expression in each group. Western blot analysis was performed to assess intracellular MPO and NE expressions. Twenty 8-week-old male mice were randomly divided into blank group, etoposide group (100 mg·kg-1), and etoposide + Renshen Yangrongtang groups with low-, medium-, and high-dose (0.1, 0.5, 2.0 g·kg-1). Except for the blank group that received PBS via gavage at room temperature, and the etoposide group that received an intraperitoneal injection for 3 days, the remaining groups received gavage of Renshen Yangrongtang for 14 consecutive days after 3 days of etoposide administration. The peripheral blood related indicators were detected through an automated hematology analyzer; Western blot analysis was performed to assess MPO and neutrophil elastase (NE) expression changes in the marrow cells of mice. Enzyme-linked immunosorbent assay (ELISA) was used to detect ROS, MPO, and NETs changes in the marrow cells of mice. MPO and NE on femur bones were stained through immunohistochemistry. Scanning electron microscopy was used to analyze the structural changes of NETs in the marrow cells of mice after drug administration. ResultsLC-MS results showed that the freeze-dried powder of Renshen Yangrongtang contained complete technical materials such as Chinese angelica, Astragalus mongholicus, and ginseng. In K562 cells, compared with the etoposide group, ELISA results indicated that the concentrations of MPO, ROS, and NETs in the etoposide + Renshen Yangrongtang medium and high-dose groups were decreased (P<0.05, P<0.01), and Western blot data showed that the etoposide high-dose group significantly reduced the expression of MPO and NE protein in K562 cells (P<0.05, P<0.01). In vivo, compared with the etoposide group, the number of RBC, WBC, and PLT in the etoposide+Renshen Yangrongtang high-dose group increased significantly (P<0.05). ELISA results suggested that in the etoposide+Renshen Yangrongtang low-, medium-, and high-dose groups, the concentration of mice ROS, MPO, and NETs significantly decreased (P<0.05, P<0.01). Western blot results revealed that compared with the etoposide group, the expressions of MPO and NE in the marrow cells of mice in the etoposide + Renshen Yangrongtang low-, medium- and high-dose groups were significantly decreased (P<0.05, P<0.01). Scanning electron microscopy observations revealed that Renshen Yangrongtang reduced the NETs structure generation in the marrow cells of mice after the influence of etoposide. ConclusionRenshen Yangrongtang can alleviate etoposide-induced myelosuppression by inhibiting ROS/MPO and reducing the formation of intracellular NETs.

OBJECTIVE To explore the effects of isorhamnetin on the development of gastric cancer through up-regulation of solute carrier family 25 member 25 antisense RNA 1(SLC25A25-AS1). METHODS Using BALB/c nude mice as the subjects, the xenograft tumor model was established by subcutaneously inoculating human gastric cancer MKN28 cells into the axillary region. The effects of low and high doses of isorhamnetin (20 and 40 mg/kg) on the tumor volume and mass in nude mice were investigated. MKN28 cells were selected and divided into control group, isorhamnetin group (70 μmol/L, similarly hereinafter), isorhamnetin+knocking down negative control group, isorhamnetin+knocking down SLC25A25-AS1 group, isorhamnetin+ overexpression negative control group and isorhamnetin+overexpressing SLC25A25-AS1 group. Effects of knocking down/ overexpressing SLC25A25-AS1 on viability, apoptosis, migration and invasion ability of isorhamnetin-treated cells were detected. After verifying the targeting relationships between microRNA-212-3p (miR-212-3p) and SLC25A25-AS1, as well as phosphatase and tensin homologue deleted on chromosome 10 (PTEN), the effects of knocking down/overexpressing SLC25A25-AS1 on the expression of miR-212-3p, PTEN mRNA, and PTEN protein in isorhamnetin-treated cells were investigated. RESULTS Compared with the model control group, tumor volume and mass of nude mice in the isorhamnetin low-dose and high-dose groups were reduced significantly, and the isorhamnetin high-dose group was significantly lower than the isorhamnetin low-dose group (P<0.05). miR-212-3p had targeting relationships with SLC25A25-AS1 and PTEN. Compared with the control group, the cell viability (intervened for 24, 48 h), migration number, invasion number and miR-212-3p expression of cells in the isorhamnetin group, isorhamnetin+knocking down negative control group and isorhamnetin+overexpressing negative control group were significantly reduced or decreased or down-regulated, while the apoptosis rate, mRNA and protein expressions of PTEN were significantly increased or up-regulated (P<0.05). Compared with isorhamnetin group and isorhamnetin+knocking down negative control group, the cell viability, migration number, invasion number and miR-212-3p expression of cells in the isorhamnetin+knocking down SLC25A25-AS1 group were significantly increased or up- regulated, while the apoptosis rate, mRNA and protein expressions of PTEN were significantly reduced or down-regulated (P< 0.05). Compared with isorhamnetin group and isorhamnetin+overexpressing negative control group, the cell viability, migration number, invasion number and miR-212-3p expression of cells in isorhamnetin+overexpressing SLC25A25-AS1 group were significantly reduced or decreased or down-regulated, while the apoptosis rate, PTEN mRNA and protein expressions were significantly increased or up-regulated (P<0.05). CONCLUSIONS Isorhamnetin may inhibit the development of gastric cancer by up-regulating the expression of SLC25A25-AS1, down-regulating miR-212-3p, and up-regulating the expression of PTEN, which is a downstream target of miR-212-3p.

Guided by the concept of quality by design(QbD), this study optimizes the calcination and quenching process of calcined Magnetitum and establishes the XRD characteristic spectra of calcined Magnetitum, providing a scientific basis for the formulation of quality standards. Based on the processing methods and quality requirements of Magnetitum in the Chinese Pharmacopoeia, the critical process parameters(CPPs) identified were calcination temperature, calcination time, particle size, laying thickness, and the number of vinegar quenching cycles. The critical quality attributes(CQAs) included Fe mass fraction, Fe~(2+) dissolution, and surface color. The weight coefficients were determined by combining Analytic Hierarchy Process(AHP) and the criteria importance though intercrieria correlation(CRITIC) method, and the calcination process was optimized using orthogonal experimentation. Surface color was selected as a CQA, and based on the principle of color value, the surface color of calcined Magnetitum was objectively quantified. The vinegar quenching process was then optimized to determine the best processing conditions. X-ray diffraction(XRD) was used to establish the characteristic spectra of calcined Magnetitum, and methods such as similarity evaluation, cluster analysis, and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to evaluate the quality of the spectra. The optimized calcined Magnetitum preparation process was found to be calcination at 750 ℃ for 1 h, with a laying thickness of 4 cm, a particle size of 0.4-0.8 cm, and one vinegar quenching cycle(Magnetitum-vinegar ratio 10∶3), which was stable and feasible. The XRD characteristic spectra analysis method, featuring 9 common peaks as fingerprint information, was established. The average correlation coefficient ranged from 0.839 5-0.988 1, and the average angle cosine ranged from 0.914 4 to 0.995 6, indicating good similarity. Cluster analysis results showed that Magnetitum and calcined Magnetitum could be grouped together, with similar compositions. OPLS-DA discriminant analysis identified three key characteristic peaks, with Fe_2O_3 being the distinguishing component between the two. The final optimized processing method is stable and feasible, and the XRD characteristic spectra of calcined Magnetitum was initially established, providing a reference for subsequent quality control and the formulation of quality standards for calcined Magnetitum.

Premature ovarian insufficiency(POI) is a manifestation of ovarian aging, with a global incidence of 3.5%. If not addressed in time, POI can rapidly develop into premature ovarian failure(POF). The incidence of POI is mainly related to genetic factors, iatrogenic factors, autoimmunity, aging, infection, psychological factors, and other influences. POI not only causes menstrual disorders, amenorrhea, infertility, and dyspareunia but also tends to present with symptoms such as mood swings, insomnia, hot flashes, fatigue, as well as osteoporosis, coronary heart disease, diabetes, and other conditions, resulting in long-term psychological and physical health concerns for affected women. From traditional Chinese medicine(TCM)'s perspective, POI is primarily attributed to kidney Yin deficiency, with the main pathogenesis rooted in kidney deficiency, which affects the heart, liver, and spleen. It manifests in different syndrome types, including kidney deficiency with liver Qi stagnation, kidney deficiency with blood stasis, and spleen-kidney Yang deficiency. TCM employs a holistic view, utilizing multi-component TCM, multi-site acupuncture, and multi-target and multi-pathway interventions to treat POI. It offers unique advantages such as strong personalization, high safety, and good efficacy. In this paper, the animal and clinical research literature on the prevention and treatment of POI in the past 10 years was systematically summarized and reviewed. It is found that TCM mainly treats POI and alleviates POI-caused issues such as menstrual disorders, infertility, and emotional instability by regulating the neuroendocrine system(hypothalamic-pituitary-ovarian axis, HPOA) and related signaling pathways, improving ovarian function and antioxidant capacity, enhancing immune function, maintaining mitochondrial energy metabolism, inhibiting ferroptosis, and controlling endoplasmic reticulum stress.

The AP2/ERF transcription factor family is a class of transcription factors widely present in plants, playing a crucial role in regulating flowering, flower development, flower opening, and flower senescence. Based on transcriptome data from flower, leaf, and stem samples of two Lonicera macranthoides varieties, 117 L. macranthoides AP2/ERF family members were identified, including 14 AP2 subfamily members, 61 ERF subfamily members, 40 DREB subfamily members, and 2 RAV subfamily members. Bioinformatics and differential gene expression analyses were performed using NCBI, ExPASy, SOMPA, and other platforms, and the expression patterns of L. macranthoides AP2/ERF transcription factors were validated via qRT-PCR. The results indicated that the 117 LmAP2/ERF members exhibited both similarities and variations in protein physicochemical properties, AP2 domains, family evolution, and protein functions. Differential gene expression analysis revealed that AP2/ERF transcription factors were primarily differentially expressed in the flowers of the two L. macranthoides varieties, with the differentially expressed genes mainly belonging to the ERF and DREB subfamilies. Further analysis identified three AP2 subfamily genes and two ERF subfamily genes as potential regulators of flower development, two ERF subfamily genes involved in flower opening, and two ERF subfamily genes along with one DREB subfamily gene involved in flower senescence. Based on family evolution and expression analyses, it is speculated that AP2/ERF transcription factors can regulate flower development, opening, and senescence in L. macranthoides, with ERF subfamily genes potentially serving as key regulators of flowering duration. These findings provide a theoretical foundation for further research into the specific functions of the AP2/ERF transcription factor family in L. macranthoides and offer important theoretical insights into the molecular mechanisms underlying floral phenotypic differences among its varieties.

Sepsis is a systemic inflammatory response caused by severe infection or trauma, and is one of the common causes of acute lung injury(ALI) and acute respiratory distress syndrome(ARDS). Sepsis-acute lung injury(SALI) is a critical clinical condition with high morbidity and mortality. Its pathogenesis is complex and not yet fully understood, and there is currently a lack of targeted and effective treatment options. Pyroptosis, a novel form of programmed cell death, plays a key role in the pathological process of SALI by activating inflammasomes and releasing inflammatory factors, making it a potential therapeutic target. In recent years, the role of traditional Chinese medicine(TCM) in regulating signaling pathways related to pyroptosis through multi-components and multi-targets has attracted increasing attention. TCM may intervene in pyroptosis by inhibiting the activation of NLRP3 inflammasomes and regulating the expression of Caspase family proteins, thus alleviating inflammatory damage in lung tissues. This paper systematically reviews the molecular regulatory network of pyroptosis in SALI and explores the potential mechanisms and research progress on TCM intervention in cellular pyroptosis. The aim is to provide new ideas and theoretical support for basic research and clinical treatment strategies of TCM in SALI.

By systematically sorting out the theoretical origin, manipulation key points, and clinical applications of sparrow-pecking needling, it is believed that sparrow-pecking needling method involves performing small-amplitude, high-frequency lifting and thrusting of the needle tip in the original position, with heavy thrusting and light lifting, starting slowly and then becoming rapid, thus forming a characteristic needling sensation that spreads to the surroundings in a wavelike manner. The sparrow-pecking needling plays a role in stimulating the conduction of channel qi and regulating the circulation of qi and blood. Additionally, this paper summarized the clinical applications of sparrow-pecking needling in five aspects, regulating mind, regulating channel sinews, regulating zang-fu organs, regulating ying-wei (nutrient and defense qi), and regulating yang qi, so as to provide references for inheriting and expanding the theory and clinical application of sparrow-pecking needling.

Purpose:
This Phase II trial was objected to evaluate the efficacy and safety of adding fulvestrant to neoadjuvant chemotherapy in patients with estrogen receptor (ER)+/human epidermal growth factor receptor 2 (HER2)– locally advanced breast cancer (LABC). Additionally, the study aimed to investigate the association of 16α-18F-fluoro-17β-fluoroestradiol (18F-FES) positron emission tomography (PET)–computed tomography (CT) and metabolites with efficacy.
Materials and Methods:
Fulvestrant and EC-T regimen were given to ER+/HER2– LABC patients before surgery. At baseline, patients received 18F-FES PET-CT scan, and plasma samples were taken for liquid chromatography–mass spectrometry analysis. The primary endpoint was objective response rate (ORR). Secondary endpoints included total pathologic complete response (tpCR) and safety.
Results:
Among the 36 patients enrolled, the ORR was 86.1%, the tpCR rate was 8.3%. The incidence of grade ≥ 3 treatment-emergent adverse events was 22%. The decrease in ER value in sensitive patients was larger than that in non-sensitive patients, as was Ki-67 (p < 0.05). The maximum standardized uptake value, mean standardized uptake values, total lesion ER expression of 18F-FES PET-CT in sensitive patients were significantly higher than those in non-sensitive patients (p < 0.05). Moreover, these parameters were significantly correlated with Miller and Payne grade and the change in ER expression before and after treatment (p < 0.05). Thirteen differential expressed metabolites were identified, which were markedly enriched in 19 metabolic pathways.
Conclusion
This regimen demonstrated acceptable toxicity and encouraging antitumor efficacy. 18F-FES PET-CT might serve as a tool to predict the effectiveness of this therapy. Altered metabolites or metabolic pathways might be associated with treatment response.
