Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Malignant tumors are one of the major causes of death in the population. Owing to limited clinical treatments, susceptibility to drug resistance, and generally low cure rates of conventional therapies, new treatment strategies need to be explored. Compared with existing therapies, traditional Chinese medicine (TCM) has unique advantages, such as low side effects, in the treatment of malignant tumors. Ferroptosis is a recently characterized form of regulated cell death associated with iron metabolism imbalance, lipid peroxidation, antioxidant system malfunction and other aspects. Studies have shown that TCM regulates Fe3+, Fe2+, glutathione, glutathione peroxidase 4 and other substances related to ferroptosis, thereby affecting lipid peroxidation and antioxidant processes, and then inducing ferroptosis. Through these mechanisms, TCM plays a key role in inhibiting the growth and spread of tumor cells and is involved in multiple stages of malignant tumor progression. In this study, we systematically retrieved the literature indexed in PbuMed and China National Knowledge Infrastructure (CNKI) with the keywords TCM, ferroptosis, and malignant tumors. We outlined the mechanisms of ferroptosis and its association with malignant tumors, and summarized the research progress on the prevention and treatment of malignant tumors through the modulation of ferroptosis by TCM monomers, single herbs, and compounds. The study aims to provide new perspectives for the prevention and treatment of malignant tumors by TCM.

Fungal infections have emerged as a critical public health issue endangering human health. However, the existing arsenal of antifungal agents is limited in diversity and is commonly plagued by drawbacks including narrow antimicrobial spectrums and the frequent emergence of drug resistance, which severely compromises the efficacy of clinical treatments. Pathogenic fungi can develop extensive adaptability to currently available drugs through multiple mechanisms, which are mainly manifested in three aspects: drug resistance, tolerance and persistence. The molecular mechanisms and regulatory pathways underlying drug resistance, tolerance and persistence in pathogenic fungi were systematically summarized in this review, and the counteractive strategies such as combination therapy and the development of novel antifungal agents were further discussed, which aimed to provide theoretical basis and practical reference for the precision treatment of fungal infections.

OBJECTIVE To investigate the effects of safflower polysaccharide (SPS) on ischemic stroke (IS) in rats by regulating the growth arrest-specific protein 6 (Gas6)/Axl receptor tyrosine kinase (Axl) signaling pathway. METHODS The modified suture-occluded method was employed to establish a rat model of middle cerebral artery occlusion (MCAO) for IS. The rats were then randomly divided into the model (Model) group, SPS low- and high-dose (SPS-L, SPS-H, 50 and 100 mg/kg) groups, and integrated traditional Chinese and Western medicine (SPS-H+Nim, SPS 100 mg/kg+Nim 15 mg/kg) group, with 10 rats in each group. Another 10 rats were selected as the sham operation (Sham) group. Rats in each group were administered corresponding doses of medication or an equal volume of normal saline intragastrically, with continuous intervention for 14 days. The neurological function of rats in each group was evaluated 24 hours after drug administration. The morphological changes in hippocampal tissue were observed. The contents of interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-α (TNF-α) in serum, the percentage of cerebral infarction area, the neuronal apoptosis rate, as well as the contents of malondialdehyde (MDA), superoxide dismutase (SOD), and brain-derived neurotrophic factor (BDNF) in hippocampal tissue, and the relative protein expression levels of Gas6, phosphorylated Axl (p-Axl), Axl, B-cell lymphoma-2 (Bcl-2), and Bcl-2 associated X protein (Bax) were measured. RESULTS Compared with Model group, the neurological function of rats in SPS-L group, SPS-H group and SPS-H+Nim group improved significantly, while serum contents of IL-6, TNF-α, and IL-1β, the percentage of cerebral infarction area, the apoptotic rate of neurons as well as MDA content and relative protein expression of p-Axl and Bax were decreased significantly ( P <0.05 or P <0.01). The contents of SOD and BDNF, as well as the relative protein expression of Gas6, Axl, and Bcl-2 in hippocampal tissue, were significantly increased ( P <0.05 or P <0.01), and the ischemic injury in hippocampal tissue imp roved to varying degrees. CONCLUSIONS SPS can reduce neuroinflammation, oxidative stress, and neuronal apoptosis in IS rats, alleviate nerve injury, and improve neurological function, which may be achieved by activating the Gas6/Axl signaling pathway.

OBJECTIVE:
To explore the genetic variants and phenotypic characteristics of patients with Neurofibromatosis type I (NF1).
METHODS:
Twenty two NF1 patients who presented at Enze Medical (Center) Group in Taizhou between 2018 and 2024 were selected as the study subjects. Clinical phenotype and family history were collected for the patients. Whole exome sequencing (WES) was carried out for the 22 probands to screen the variants of NF1 gene. Candidate variants were verified by Sanger sequencing of their family members. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: K20230902).
RESULTS:
The 22 probands were diagnosed between the age of 5 months to 47 years old, and have all shown cafe au lait spots on their skin. Seventeen patients exhibited the phenotype at birth, and 11 had various degrees of neurofibromatosis. Among them, probands 1 and 13 underwent surgical resection of the tumor but had recurred, while proband 12 had amputation due to the huge size and serious impact of the neurofibroma and had no recurrence. Five patients had various degrees of scoliosis. In total 22 germline mutations and one somatic mutation were identified among the 22 families, with 5 variants unreported previously, including 1 nonsense mutation c.1603C>T (Q535*), 3 frameshift mutations [c.7268_7269delCA (Thr2423fs), c.2293del (Arg765Alafs*26), and c.5433_5438delinsGC (Phe1812ArgfsTer50)], and 1 deletion involving exons 41-44 of the NF1 gene and adjacent introns. Proband 13 was found to harbor germline mutation c.6796C>T (Gln2266Ter) and somatic mutation c.1019_1020del (Ser340Cysfs Ter12) in the peripheral blood and tumor tissue, respectively. Among the 22 NF1 probands, 6 had received treatment due to severe illness. Proband 1 had tumor resection in the right upper limb, but was found to have malignant lung tumor and died during follow-up. Proband 12 had multiple recurrence of neurofibroma in the left ring finger. Proband 4 underwent spinal correction surgery due to severe scoliosis. Proband 11 had died due to a central nervous system disease. Among the 22 germline mutations, 6 had led to the occurrence of truncated proteins, which may have a more severe impact on the phenotype.
CONCLUSION
This study investigated the genetic variants and clinical phenotypes of 22 NF1 families and identified 5 novel variants of the NF1 gene, which has expanded the genotypic and phenotypic spectra of the NF1. Preliminary studies have identified an association between truncated mutations, young age, and severe phenotypes, which may provide important clues for prognosis evaluation. For the clinical diagnosis and treatment of NF1, it is necessary to consider the phenotypic characteristics and genetic testing in combination with genetic counseling and long-term follow-up.

ObjectiveTo investigate the effects of Jianpi Qinghua granules on blood glucose fluctuations in patients with newly diagnosed overweight/obese type 2 diabetes mellitus (T2DM) and Qi-Yin deficiency syndrome from the perspective of skeletal muscle mass and function, while providing new insights for the treatment of diabetes. MethodsThis study employed a randomized, double-blind, placebo-controlled design. A total of 110 newly diagnosed overweight/obese T2DM patients meeting the inclusion criteria were randomly assigned to either the traditional Chinese medicine (TCM) group (54 cases) or the control group (56 cases). Patients in the TCM group received Jianpi Qinghua Granules, while those in the control group received a placebo. Both groups underwent dietary and exercise guidance. After 12 weeks of intervention, blood glucose fluctuations were assessed using the following parameters: time in the target blood glucose range (TIR), mean daily blood glucose (MBG), standard deviation of mean daily blood glucose (SDBG), mean amplitude of glycemic excursions (MAGE), coefficient of variation of blood glucose (CV), glycated hemoglobin (HbA1c) achievement rate, fasting plasma glucose (FPG), and 2 hour postprandial glucose (2 hPG). Skeletal muscle mass was measured by dual-energy X-ray absorptiometry (DXA), while skeletal muscle function was evaluated using a handheld dynamometer for distal muscle strength and a 5-time sit-to-stand test for lower limb function. Additionally, pancreatic islet function and TCM syndrome scores were analyzed. ResultsNo significant differences were observed in baseline data between the two groups before intervention, ensuring comparability. After treatment, compared to the control group, the TCM group showed a significant increase in TIR (P<0.01). While the SDBG and CV decreased, and MBG and MAGE increased in the TCM group, these differences were not statistically significant. Notably, the TCM group exhibited significant reductions in 2 hPG (P<0.01) and HbA1c (P<0.05), though the decrease in FPG was not statistically significant. The HbA1c achievement rate in the TCM group was significantly higher than that in the control group (χ2=45.498, P<0.01). In terms of skeletal muscle mass and function, the TCM group demonstrated a significant increase in handgrip strength (P<0.01) and a significant reduction in the 5-time sit-to-stand duration (P<0.05). However, although body fat percentage increased, leading to a decrease in skeletal muscle mass and the ratio of skeletal muscle to fat, these changes were not statistically significant. For pancreatic islet function, the TCM group showed significant reductions in fasting insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR) (P<0.01). Additionally, the TCM syndrome score in the TCM group was significantly reduced (P<0.01). ConclusionJianpi Qinghua granules may reduce blood glucose fluctuations in newly diagnosed overweight/obese T2DM patients with Qi-Yin deficiency syndrome by enhancing skeletal muscle function, improving pancreatic islet function, and ameliorating related TCM syndromes.

Vascular endothelial growth factor (VEGF) inhibitors are drugs that target and inhibit tumor angiogenesis. By blocking the signaling pathway of VEGF and its receptor, they suppress tumor proliferation and play a crucial role in tumor treatment. However, their side effects, such as hypertension, proteinuria, hand-foot skin reactions, and myelosuppression, during treatment seriously affect patients' treatment compliance and quality of life. The development of intervention strategies for the side effects of VEGF inhibitors is of great importance for tumor treatment. This article reviews the clinical characteristics and toxic mechanisms of common side effects caused by VEGF inhibitors during tumor treatment and summarizes intervention strategies that combine traditional Chinese and Western medicines. Drug dosages were precisely monitored and adjusted to achieve antitumor treatment. Patients' discomfort symptoms are improved through prescriptions that act by tonifying qi and promoting blood circulation, strengthening the spleen, and tonifying the kidney. The combination of traditional Chinese and Western medicines is used to treat patients, thus providing a safe and effective treatment plan for patients with cancer.

Evaluating the absorption of traditional Chinese medicine (TCM) formulations in skin has long been a challenge in cutaneous pharmacokinetic studies of TCM. In recent years, various new techniques, including diffusion cell, microphysiological system, matrix-assisted laser desorption/ionization mass spectrometry imaging, tape stripping, microdialysis/open-flow microperfusion, and confocal Raman microscopy technology, have been developed to characterize and predict the pharmacokinetic profiles of these formulations more accurately. This review systematically summarizes the application progress of these methods in the evaluation of cutaneous pharmacokinetics of TCM, highlights their technical features and suitable scenarios, and discusses future development trends, providing new research perspectives for further understanding the dynamic changes, spatial distribution characteristics of active ingredients in the skin, and the rationality of compatibility in topical preparations.
10.Epidemiological characteristics of category C intestinal infectious diseases among children and adolescents in Shenzhen from 2012 to 2024 and the association with meteorological factors
Chinese Journal of School Health 2026;47(4):553-557
Objective:
To analyze the epidemiological characteristics of category C intestinal infectious diseases among children and adolescents in Shenzhen from 2012 to 2024 and the association with meteorological factors, so as to provide a scientific basis for the targeted prevention and control of infectious diseases for children and adolescents.
Methods:
Using data from the "Infectious Disease Reporting Information Management System" of the "China Disease Prevention and Control Information System" covering the period from January 1, 2012 to December 31, 2024, the study analyzed clinical and confirmed cases of hand, foot, and mouth disease, other infectious diarrhea, and acute hemorrhagic conjunctivitis among individuals aged 6-19 years old to describe demographic and temporal characteristics. It used Joinpoint regression to calculate the average annual percent change (AAPC) and annual percent change (APC) to analyze incidence trends, and Spearman s correlation was combined to generalize linear models so as to assess the association between category C intestinal infectious diseases and meteorological factors.
Results:
From 2012 to 2024, a cumulative total of 61 019 cases of hand, foot, and mouth disease among children and adolescents, 58 498 cases of other infectious diarrhea, and 6 377 cases of acute hemorrhagic conjunctivitis were reported. The AAPC in the incidence rates of these three diseases was 19.19%, 31.03% and 31.48 %, respectively(all P <0.05). Notably, the incidence of hand, foot, and mouth disease increased significantly after 2022 (APC= 133.66 %, P <0.01). The temporal distribution showed that hand,foot,and mouth disease was most prevalent in May,June and July (seasonal index of 2.39,3.64,1.97), other infectious diarrhea was most prevalent in February,March and December (seasonal index of 1.22,1.25,1.47), and acute hemorrhagic conjunctivitis peaked in September and October (seasonal index of 4.22,2.16). Monthly average temperature could increase the risk of hand,foot,and mouth disease( β = 0.18 ,95% CI =0.11-0.25); as monthly average wind speed increased, the incidence of other infectious diarrhea ( β =-0.86, 95% CI = -1.50 to -0.22) and acute hemorrhagic conjunctivitis ( β =-1.32, 95% CI =-2.60 to -0.05) both decreased (all P < 0.05 ).
Conclusions
Among children and adolescents in Shenzhen, category C intestinal infectious diseases remain prevalent throughout the year;the number of reported hand, foot, and mouth disease cases has shown an upward trend in recent years.Temperature and wind speed significantly affect the number of reported cases of three types with category C intestinal infectious diseases.
