AIM: To compare the control effect of spherical and toric orthokeratology on low-to-moderate myopia with astigmatism(-1.00--1.50 DC)in adolescents.METHODS: The clinical data of 119 cases(119 eyes)of low-to-moderate myopia with astigmatism(-1.00--1.50 DC)adolescents who were treated and fitted with orthokeratology in the ophthalmology department of Sichuan Provincial People's Hospital from June 2021 to January 2022 were retrospectively analyzed. They were divided into spherical group, with 65 cases(65 eyes), and toric group, with 54 cases(54 eyes)according to the type of orthokeratology. The changes of uncorrected visual acuity(UCVA), axial length and corneal astigmatism before and after wearing lenses were recorded to evaluate the therapeutic effect.RESULTS: The UCVA of both the groups significantly improved at 1 and 2 a after wearing lenses(all P<0.01); corneal astigmatism decreased, but there was no significant difference(all P>0.05); the axial length was longer than that before wearing lenses(P<0.01). There were no statistical significant differences in the UCVA and corneal astigmatism between the spherical group and the toric group(Fintergroup=0.829,Pintergroup=0.364; Fintergroup=0.997,Pintergroup=0.320); and there were no statistical significant differences in the axial length growth between the spherical group and the toric group after wearing lenses for 1 a(0.18±0.11 mm vs 0.17±0.14 mm), and 2 a(0.17±0.10 mm vs 0.16±0.10 mm; all P>0.05).CONCLUSION: Both orthokeratology lenses can improve the UCVA, reduce corneal astigmatism, and delay axial length growth of adolescents with low-to-moderate myopia with astigmatism(-1.00--1.50 DC), and there are no significant differences in the control effect of spherical design orthokeratology and the toric design orthokeratology on myopia.

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.

ObjectiveTo explore the establishment of performance assessment indicators for the classification and grading of public health staff in district-level Centers for Disease Control and Prevention (CDCs), and to provide a basis for such evaluations. MethodsThrough literature review and group interviews, performance evaluation indicators were developed based on competency evaluation. Experts were invited to evaluate the weight of performance evaluation indicators for public health staff from different categories, with the average value used to represent the weight of each indicator. ResultsTwenty-nine experts from universities in Shanghai, municipal CDCs, and district CDCs participated, yielding an expert authority coefficient of 0.86. The performance evaluation indicators for department managers were categorized into three levels, with 4 indicators at the primary level, 16 indicators at the secondary level, and 42 indicators at the tertiary level, while those for general staff included 4 primary indicators, 15 secondary indicators, and 36 tertiary indicators. Significant differences were observed in the weight coefficients of the primary indicators (internal operations, professional work, and learning and growth) between department managers and general staff. The top three secondary indicators for department managers were department management, monitoring and prevention, and level of expertise. For mid-level and senior staff, the top three secondary indicators were monitoring and prevention, level of expertise, and research work. The top three secondary indicators for junior staff were monitoring and prevention, professional expertise, and professional attitude. No significant statistical differences were found among tertiary indicators. ConclusionThe developed performance evaluation indicators are reliable. Staff at different levels and classifications should be evaluated using different performance evaluation standards to accurately reflect individual performance and contributions.

OBJECTIVE: To observe the clinical efficacy of 3D printing spinal external fixator combined with McKenzie therapy for patients with lumbar dics herniation (LDH). METHODS: Sixty patients with LDH between January 2022 and January 2023 were enrolled. Among them, 30 patients were given McKinsey training. According to different treatment methods, all patients were divided into McKenzie group and McKenzie + 3D printing group, 30 patients in each group. The McKenzie group provided McKenzie therapy. The McKenzie + 3D printing group were treated with 3D printing spinal external fixation brace on the basis of McKenzie therapy. Patients in both groups were between 25 and 60 years of age and had their first illness. In the McKenzie group, there were 19 males and 11 females, with an average age of (48.57±5.86) years old, and the disease duration was (7.03 ±2.39) months. The McKenzie + 3D printing group, there were 21 males and 9 females, with an average age of (48.80±5.92) years old, and the disease duration was(7.30±2.56) months. Pain was evaluated using the visual analogue scale (VAS), and lumbar spine function was assessed using the Oswestry disability index (ODI) and the Japanese Orthopaedic Association (JOA) score. VAS, ODI and JOA scores were compared between two groups before treatment and at 1, 3, 6, 9 and 12 months after treatment. RESULTS: All patients were followed up for 12 months. The VAS for the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(6.533±0.860), (5.133±1.008), (3.933±0.868), (2.900±0.759), (2.067±0.640), (1.433±0.504), respectively. In the McKenzie group, the corresponding scores were (6.467±0.860), (5.067±1.048), (4.600±0.968), (3.533±1.008), (2.567±0.728), (1.967±0.809), respectively. The ODI of the McKenzie group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were (41.033±6.810)%, (37.933±6.209)%, (35.467±6.962)%, (27.567±10.081)%, (20.800±7.531)%, (13.533±5.158)%, respectively. For the McKenzie combined with 3D printing group, the corresponding ODI were(38.033±5.605)%, (33.000±6.192)%, (28.767±7.045)%, (22.200±5.517)%, (17.700±4.836)%, (11.900±2.771)%, respectively. The JOA scores of the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(8.900±2.074), (13.133±2.330), (15.700±3.583), (20.400±3.480), (22.267±3.084), (24.833±2.640), respectively. In the McKenzie group, the corresponding scores were(9.200±2.091), (12.267±2.406), (15.333±3.198), (18.467±2.240), (20.133±2.751), (22.467±2.849), respectively. Before the initiation of treatment, no statistically significant differences were observed in the VAS, ODI, and JOA scores between two groups (P>0.05). At 3, 6, 9, and 12 months post-treatment, the VAS in the McKenzie combined with 3D printing group was significantly lower than that in the McKenzie group, and the difference was statistically significant (P<0.05). The comparison of ODI between two groups at 1, 3, 6, 9, and 12 months post-treatment revealed statistically significant differences (P<0.05). At 6, 9, and 12 months post-treatment, the JOA score in the McKenzie combined with 3D printing group was significantly higher than that in the McKenzie-only group, and the difference was statistically significant (P<0.05). CONCLUSION The combination of 3D printed functional spinal external fixation brace with McKenzie therapy can significantly improve and maintain lumbar function in patients with LDH.

OBJECTIVE: To analyze the clinical characteristics and outcomes of multiple myeloma (MM) patients infected with Listeria monocytogenes (LM) in novel agent era, so as to improve clinicians' understanding. METHODS: Clinical data of 4 MM patients infected with LM in Beijing Chao-yang Hospital from October 2018 to October 2022 was analyzed retrospectively. RESULTS: The average age of the 4 patients was (57.5±4.1) years old. All the patients did not reach deep remission from induction therapy or experienced multiple recurrences of MM, with significant decreased immunoglobulin levels and lymphocyte counts. The initial clinical manifestation was all fever. Three patients developed nervous system symptoms 2-3 days after onset and cerebrospinal fluid examination indicated meningitis. The sensitive anti-infection agents were given according to pathogenic test results 4-5 days after onset. After treatment, two patients recovered, one patient gave up treatment and died after discharged from hospital, and one critical patient died despite exposure to sensitive antibiotics. CONCLUSION MM patients, with the application of novel agents, may have increased risk of LM infection, even critical cases. LM prevention and prompt therapy in early stage for suspected patients is key to reducing the risk of severe infection and mortality.

Transposable elements (TEs), once considered genomic "junk", are now recognized as critical regulators of genome function and human disease. These mobile genetic elements-including retrotransposons (long interspersed nuclear elements [LINE-1], Alu, short interspersed nuclear element-variable numbers of tandem repeats-Alu [SVA], and human endogenous retrovirus [HERV]) and DNA transposons-are tightly regulated by multilayered mechanisms that operate from transcription through to genomic integration. Although typically silenced in somatic cells, TEs are transiently activated during key developmental stages-such as zygotic genome activation and cell fate determination-where they influence chromatin architecture, transcriptional networks, RNA processing, and innate immune responses. Dysregulation of TEs, however, can lead to genomic instability, chronic inflammation, and various pathologies, including cancer, neurodegeneration, and aging. Paradoxically, their reactivation also presents new opportunities for clinical applications, particularly as diagnostic biomarkers and therapeutic targets. Understanding the dual role of TEs-and balancing their contributions to normal development and disease-is essential for advancing novel therapies and precision medicine.

With the advancement in big data and artificial intelligence technologies, the extensive application of omics technologies in traditional Chinese medicine(TCM) research has generated large experimental datasets, enabling the exploration of cross-scale correlations among massive data and thereby resulting in the shift toward a data-intensive research paradigm. The emerging approach of multi-omics data fusion analysis, emphasizing technical and computational tools, presents a potential breakthrough in this field. The holistic perspective of TCM aligns with the concept of multi-omics data fusion, yet the data types encountered exhibit high dimensionality with small sample sizes, necessitating data processing techniques such as dimensionality reduction. The current challenge lies in selecting suitable analytical methods for these data to enhance the systematic understanding of physiological functions and disease diagnosis/treatment processes. This paper explores the theories and frameworks of multi-omics data fusion, analyzes methods for fusing high-dimensional, small-sample multi-omics data in TCM, and aims to provide insights for advancing TCM research.

Objective:To summarize the clinical characteristics, diagnosis and treatment experience of salivary pleomorphic adenoma in children. Methods:Thirty patients with salivary pleomorphic adenomas treated in Beijing Childrens Hospital from January 2008 to December 2022 were retrospectively reviewed, including 11 boys and 19 girls, with the age ranging from 0.3 to 14.4 years（median age 10.4 years）. Initial presentation, medical history, imaging workups, surgical approaches, complications, rates of recurrence were evaluated. Results:Major salivary gland lesions were most common（n=24, 80%）; 53.3%（16 of 30） arising in the submandibular glands and 26.7%（8 of 30） in the parotid. Minor salivary gland lesions（n=6, 20%） were removed from the palate, tongue, face, trachea, nasopharynx, and upper mediastinumand. Preoperative imaging was reviewed in all patients and consisted of 26 ultrasound exams, 2 computerized tomography（CT） exams, and 15 magnetic resonance imaging（MRI） exams. Fine needle aspiration biopsy was performed in 12 patients. Surgical excision was performed in all patients. Postoperative complications included transient facial paresis（n=3）, Pneumonia and pleural effusion（n=1）. Average length of follow-up was 36.7 months; confirmed recurrence occurred in one patients. Conclusion:The symptoms of salivary gland pleomorphic adenoma in children are different according to the location of the tumor. The treatment is complete surgical resection, and a small amount of normal tissue around the tumor should be removed to reduce recurrence.

The anterior cingulate cortex (ACC) has recently been proposed as a key player in the representation of itch stimuli. However, to date, little is known about the contribution of specific ACC interneuron populations to itch processing. Using c-Fos immunolabeling and in vivo Ca²⁺ imaging, we reported that both histamine and chloroquine stimuli-induced acute itch caused a marked enhancement of vasoactive intestinal peptide (VIP)-expressing interneuron activity in the ACC. Behavioral data indicated that optogenetic and chemogenetic activation of these neurons reduced scratching responses related to histaminergic and non-histaminergic acute itch. Similar neural activity and modulatory role of these neurons were seen in mice with chronic itch induced by contact dermatitis. Together, this study highlights the importance of ACC VIP⁺ neurons in modulating itch-related affect and behavior, which may help us to develop novel mechanism-based strategies to treat refractory chronic itch in the clinic.

To investigate the protective effects and underlying mechanisms of Qin-Zhu-Liang-Xue decoction (QZLX) in atopic dermatitis (AD) and glucocorticoid resistance, we conducted a single-blinded, randomized controlled clinical trial to evaluate the efficacy and safety of this concoction. Network pharmacology analysis was performed and validated through clinical studies. The efficacy, safety, and mechanism of action of QZLX and glucocorticoid receptor (GR) α recombinant protein were assessed in AD mice induced by 2,4-dinitrofluorobenzene (DNFB). Correlation analysis was performed to determine the clinical relevance of GRα. The trial demonstrated that patients who received QZLX showed considerable improvements in their Scoring Atopic Dermatitis (SCORAD) and Dermatology Life Quality Index (DLQI) scores compared with those who received mizolastine at week 4. Network pharmacological analysis identified GRα as a key target for QZLX in AD treatment. QZLX administration increased the serum GRα expression in AD patients, alleviated AD symptoms in mice, decreased inflammatory cytokine expression, and increased GRα expression without affecting liver or kidney function. In addition, GRα recombinant protein improved AD-like skin lesions in DNFB-induced mice. A negative correlation was observed between GRα expression and clinical parameters, including SCORAD, DLQI, and serum IgE levels. QZLX alleviates AD symptoms through the upregulation of GRα and thus presents a novel therapeutic strategy for the prevention of glucocorticoid resistance in AD management.
