ObjectiveThe development trend and knowledge structure of the research on human use experience （HUE） of traditional Chinese medicine （TCM） were systematically reviewed， and the core challenges and future directions were identified. This study aims to provide reference for the construction of a scientific and feasible research and development framework and evidence transformation system. MethodsLiterature related to "human use experience" published from January 1， 2019 to July 31， 2025 was retrieved from the China National Knowledge Infrastructure （CNKI）， Wanfang， China Science and Technology Journal Database （VIP）， and PubMed databases. Bibliometric visualization was conducted using Excel， VOSviewer， and CiteSpace， followed by in-depth reading and thematic summarization of core literature. ResultsA total of 181 papers were included for bibliometric analysis， with 45 articles used for in-depth thematic mining. The analysis showed that the number of publications on HUE research has increased in a stepwise manner over the past five years. Yang Zhongqi （24 times） was the core of the author network， the journal with the highest number of publications was China Journal of Chinese Materia Medica， the institutions publishing the most articles were mainly research institutions， regulatory agencies， hospitals， and universities， high-frequency keywords included "new TCM drugs"， "real-world studies"， and "clinical comprehensive evaluation"， keyword clustering analysis formed three major clusters： Policy orientation， application fields， and methodological approaches. Thematic analysis reveals that HUE-based evaluation should be integrated throughout the research and development process， encompassing three dimensions： TCM theory， clinical value， and pharmaceutical fundamentals， with toxic herbs and compatibility contraindications being key foci. Data collection primarily relies on empirical data， while real-world data constitute the primary source for clinical research， with efficacy and safety as the shared core. Data management emphasizes quality control and statistical analysis； however， the management of bias and confounding remains a critical bottleneck in evidence transformation. In practice， HUE-based approaches have successfully supported the registration and evaluation of multiple categories of new TCM drugs. ConclusionThe research on HUE of TCM has formed a policy-driven pattern characterized by， rapid development and close link with regulatory practice. A technical framework covering the whole chain of research and development has been constructed with clinical value as the core， which provides methodological basis and strategy reference for the scientific transformation of HUE of TCM from "experience" to "evidence".

ObjectiveGastrodia elata has evolved ecological types with shortened rhizome internodes and diversified flower and fruit coloration in response to different altitudes. Studying the genetic mechanisms of different ecotype germplasm is significant for guiding variety breeding in different cultivation areas. MethodsThe bHLH gene family was identified based on the whole-genome datasets of G. elata f. elata and G. elata f. glauca. Subsequently， the gene family members were subject to analysis， including gene structure， chromosomal localization， cis-acting elements， gene synteny， and phylogeny. Combined with transcriptome data and quantitative Real-time PCR， the expression patterns of bHLH genes in the stems of the different G. elata ecotype germplasm were analyzed. Finally， correlation analysis was conducted between gene expression patterns and color to obtain the key bHLH genes regulating the color formation of stem. ResultsA total of 63 bHLH genes were identified in both G elata f. elata and G. elata f. glauca， unevenly distributed across 17 chromosomes and clustered into 16 subfamilies， with significant expansion in some family members. Obvious inversions of bHLH genes on the same chromosome and interchromosomal translocations were detected in the two ecotype germplasm. Among these genes， 12 bHLH genes （such as bHLH62-3 and bHLH74） were associated with the bright yellow color of G elata f. elata stem， while 9 bHLH genes （such as PIL13， UNE12， and bHLH130） were correlated with the red color of G. elata f. glauca stem. Compared to G. elata f. glauca， the bHLH48 expression level was significantly higher in flowers and scale leaves of G elata f. elata， and the bHLH62-3 expression level was significantly higher in all organs of G elata f. elata. ConclusionsFunctional pathway divergence of the bHLH family members has occurred across different chromosomes in G elata f. elata and G. elata f. glauca. Through synergism or antagonism with other genes， 21 bHLH genes participate in the coloration metabolic pathway regulation of stems， flowers， and fruits. Specifically， bHLH62-3 is involved in regulating stem color differentiation in the anthocyanin biosynthesis pathway of G. elata， thus relevant to the color formation of stem. Additionally， GebHLH48 positively regulates flowering-related pathways to promote the early-flowering phenotype of G. elata f. elata. These findings have laid the foundation for analyzing the genetic regulatory mechanisms underlying the color formation of the G. elata stem.

Recent studies have indicated that the expression of ubiquitin-specific protease 51 (USP51), a novel deubiquitinating enzyme (DUB) that mediates protein degradation as part of the ubiquitin‒proteasome system (UPS), is associated with tumor progression and therapeutic resistance in multiple malignancies. However, the underlying mechanisms and signaling networks involved in USP51-mediated regulation of malignant phenotypes remain largely unknown. The present study provides evidence of USP51's functions as the prominent DUB in chemoresistant triple-negative breast cancer (TNBC) cells. At the molecular level, ectopic expression of USP51 stabilized the 78 kDa Glucose-Regulated Protein (GRP78) protein through deubiquitination, thereby increasing its expression and localization on the cell surface. Furthermore, the upregulation of cell surface GRP78 increased the activity of ATP binding cassette subfamily B member 1 (ABCB1), the main efflux pump of doxorubicin (DOX), ultimately decreasing its accumulation in TNBC cells and promoting the development of drug resistance both in vitro and in vivo. Clinically, we found significant correlations among USP51, GRP78, and ABCB1 expression in TNBC patients with chemoresistance. Elevated USP51, GRP78, and ABCB1 levels were also strongly associated with a poor patient prognosis. Importantly, we revealed an alternative intervention for specific pharmacological targeting of USP51 for TNBC cell chemosensitization. In conclusion, these findings collectively indicate that the USP51/GRP78/ABCB1 network is a key contributor to the malignant progression and chemotherapeutic resistance of TNBC cells, underscoring the pivotal role of USP51 as a novel therapeutic target for cancer management.

Background Enhancing the sense of honor and belonging among medical staff is a key component of establishing a modern hospital management system. Compared to medical staff at general hospitals, medical staff at oncology hospitals are more prone to job burnout, yet few studies in China have focused on job burnout among employees in oncology hospitals. Objective To propose a hypothetical model in which job well-being moderates the relationship between stressors and occupational burnout, to explore how stressors influence burnout and potential moderating role of job well-being, and to provide better understanding of job burnout and motivate employees based on the double-edge sword effect of stressors. Methods A cross-sectional survey was conducted in May 2022 at a tertiary oncology specialty hospital in Chongqing, China. A total of 1 898 medical staff were recruited. Data were collectedthrough four scales including a general information questionnaire, Maslach Burnout Inventory-Human Service Survey, Work Stressor Scale, and Occupational Well-being Scale for Medical Staff. Independent sample t-tests and one-way ANOVA were used for univariate comparisons of job burnout. Pearson correlation analysis was employed to examine the relationships between job burnout, stressors, and job well-being. Hierarchical linear regression was conducted to identify factors influencing job burnout and to examine potential moderating role of job well-being in the relationship between stressors and job burnout. Results A total of 2 123 questionnaires were distributed, with 1 898 valid responses, yielding an effective response rate of 89.4%. The prevalence of job burnout was 60.1%. The correlation coefficient was 0.717 (P<0.001) between stressors and burnout, −0.784 (P<0.05) between job well-being and burnout, and −0.744 (P<0.001) between stressors and job well-being. The quadratic stressors showed a statistically significant effect on burnout (β=0.404, P<0.01). Job well-being positively moderated the relationship between the linear stressors and burnout (β=1.289, P<0.001) and negatively moderated the relationship between the quadratic stressors and job burnout (β=−0.571, P<0.01), explaining 7.1% of the variance. Conclusion Job burnout prevalence is relatively high among employees in oncology hospitals. There is a curvilinear relationship between stressors and job burnout, with job well-being moderating this relationship. From a practical perspective, it is recommended to establish a tiered stress alert system to monitor employees’ stress levels and prevent prolonged exposure to high-pressure conditions. Additionally, improving employees’ job well-being through institutional incentives and developmental support can enhance its moderating role in mitigating the adverse effects of stressors on job burnout. Meanwhile, fostering coordinated responses between organizations and individuals is crucial for strengthening mental health management systems, thereby supporting a healthy, stable, and sustainable development of the healthcare workforce.

OBJECTIVE: To compare clinical efficacy between side-opening and front-opening bone cement injectors in percutaneous kyphoplasty(PKP) for the management of thoracolumbar osteoporotic vertebral compression fractures(OVCFs). METHODS: A retrospective cohort study was conducted, comprising 62 patients with single-segment thoracolumbar OVCFs (T₁₁-L₂), who underwent bilateral PKP at our department during the period from June 2020 to October 2021. Patients were categorized into two groups based on the specific bone cement injector employed during the surgical procedure: the side-opening group (n=29) and the front-opening group (n=33). Among them, the side-opening group consisted of 6 male and 23 female patients, with a mean age of (73.32±9.11) years. The front-opening group included 7 male and 26 female patients, with a mean age of (71.29±10.39) years. The variables encompassed essential patient characteristics were recorded, such as gender, age, bone mineral density (BMD), and fracture level (T₁₁-L₂), as well as procedural aspects, including operation duration, cement injection volume, cement distribution type (lobular or diffuse), occurrence of cement leakage, pre-and post-operative visual analogue scale (VAS) pain scores, and vertebral compression ratio. RESULTS: All patients underwent successful surgery, with a mean follow-up duration of (15.37±3.03) months. There were no statistically significant differences in gender, age, BMD, fracture level, preoperative vertebral compression degree, and VAS scores between the side-opening group and the front-opening group (P>0.05). The operation time, the mean cement injection volumes, the distribution of bone cement within the vertebrae has no statistically significant difference between two groups(P>0.05). Both the side-opening and front-opening groups showed significant improvements in VAS scores at 3 days and 6 months after operation (P<0.05). However, there was no significant difference in VAS scores between the two groups at both 3 days and 6 months after the operation (P>0.05). CONCLUSION Side-opening bone cement injectors in bilateral PKP surgery for single-segment thoracolumbar OVCF achieve similar clinical efficacy as front-opening injectors, without significant improvement in cement distribution and containment.

OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

AIM:To investigate the relationship between the level of monocyte chemoattractant protein-1(MCP-1)in the aqueous humor and macular microcirculation in patients with macular edema secondary to retinal vein occlusion(RVO-ME).METHODS:A total of 327 patients(327 eyes)with RVO-ME treated in our hospital from July 2022 to July 2024 were selected as the research objects. According to the recurrence or not, they were divided into non-recurrence group(291 cases, 291 eyes)and recurrence group(36 cases, 36 eyes). The clinical data, macular microcirculation index and MCP-1 level were collected. Unordered multinomial Logistic regression was used to analyze the effect of MCP-1 on RVO-ME recurrence after excluding the influence of other factors. Cubic spline was used to analyze the dose-response relationship between macular microcirculation indexes and MCP-1 expression level and RVO-ME recurrence. Multiple linear regression was used to analyze the relationship between macular microcirculation parameters and MCP-1 expression level, and the difference of MCP-1 expression level in recurrence under different macular microcirculation parameters was analyzed. Bootstrap method was used to test the mediating effect of macular microcirculation indexes on MCP-1 expression level and RVO-ME recurrence.RESULTS: The course of ME, the incidence of vitreomacular traction(VMT), the incidence of fibrous membrane epiretinal membrane(ERM), best corrected visual acuity(BCVA), hyperreflective foci in the inner and outer retinal layers(HRF), the frequency and dose of anti-vascular endothelial growth factor(VEGF)injection in the recurrence group were significantly higher than those in the non-recurrence group(all P<0.05). The external limiting membrane(ELM)integrity and ellipsoid zone(EZ)integrity in the recurrence group were significantly worse than those in the non-recurrence group(all P<0.05). The central foveal thickness(CFT), central macular thickness(CMT), superficial capillary plexus(SCP)vascular density, deep capillary plexus(DCP)vascular density and MCP-1 in the recurrence group were higher than those in the non-recurrence group(all P<0.05), and the foveal avascular zone(FAZ)area was lower than that in the non-recurrence group(P<0.05). Logistic analysis showed that MCP-1 was a risk factor for RVO-ME recurrence before and after adjusting for confounding factors. There was a significant non-linear dose-response relationship between macular microcirculation indexes and MCP-1 expression and the risk of RVO-ME recurrence(non-linear test, all P<0.001). The vascular density of CFT, CMT, SCP and DCP was positively correlated with the expression level of MCP-1(all P<0.05), while the FAZ was negatively correlated with MCP-1 expression level(P<0.05). With the increase of vessel density in CFT, CMT, SCP and DCP, and the decrease of FAZ, the expression level of MCP-1 increased, and the risk of RVO-ME recurrence showed an upward trend. The proportion of MCP-1 in Q3(>28.47 pg/mL)group was the highest(P<0.05). Macular microcirculation parameters play a mediating effect between MCP-1 expression level and RVO-ME recurrence.CONCLUSION: The level of MCP-1 in aqueous humor is positively correlated with RVO-ME recurrence, and it is closely related to macular microcirculation. Macular microcirculation has a mediating effect between MCP-1 level and RVO-ME recurrence.

Objective To understand the current situation of reprocessing reusable sterilized items in the central sterile supply departments(CSSD)of hospitals and provide a scientific basis for further standardized management.Methods Using the convenience sampling method,a self-designed questionnaire on the current situation of reprocessing of reusable disinfection items in CSSDs was used to conduct a survey in 31 provinces(autonomous regions and municipalities)from June 11th to 23rd,2024.The questionnaire covered 2 aspects,including the basic situation of the hospital and the reprocessing of disinfection items.Results A total of 1 835 questionnaires were distributed,and 1 603 valid questionnaires were retrieved.Regarding the use of reusable disinfection items,with the most frequently used items being humidification bottles,tourniquets,breathing bags and their accessories,and ventilator tubing systems etc.Among them,1 558 hospitals(97.19％)established standardized disposal procedures,and 996 hospitals(62.13％)assigned dedica-ted personnel to be responsible.In terms of the reprocessing procedures of reusable disinfection items,all 1 603 hospitals carried out drying process for the items;the main packaging method was plastic self-sealing bags(59.95％),and 541 hospitals(33.75％)sterilized the packaging materials.Additionally,935 hospitals(58.33％)used oil-free air compressors;among them,51 hospitals(58.62％)installed activated carbon filters at the end of the compressors.Conclusion The current situation of reprocessing reusable sterilized items in CSSDs of nationwide hospitals needs improvement.It is recommended to strengthen the training of professional disinfection knowledge,unify the sterilization standards for plastic self-sealing bags,develop a storage management system,and adopt a medical air compressor system without oil and water to reduce the risk of hospital infections.
