ObjectiveBased on traditional quality evaluation of Gardeniae Fructus(GF) recorded in historical materia medica, this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics, microscopic features, and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length, diameter and individual fruit weight of wild and cultivated GF, and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF, and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently, the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China, the starch content was measured by anthrone colorimetric method, the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method, the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection(HPLC-ELSD), and the contents of representative components in them were measured by ultra-performance liquid chromatography(UPLC). Finally, correlation analysis was conducted between quality traits and phenotypic traits, combined with multivariate statistical analysis methods such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA), key differential components between wild and cultivated GF were screened. ResultsIn terms of traits, the wild GF fruits were smaller, exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger, displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF, while the blue-yellow value(b*) of wild GF was significantly higher than that of cultivated GF. In the microstructure, the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals, while the endocarp contained stone cell class round, polygonal or tangential prolongation, undeveloped seeds were visible within the fruit. In contrast, the mesocarp of cultivated GF contained few calcium oxalate cluster crystals, or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like, with the innermost layer arranged in a grid pattern. Seeds were basically mature, and only a few immature seeds existed in some batches. Regarding primary metabolite content, wild GF exhibited significantly higher total polysaccharide level than cultivated GF(P<0.01). In category-specific component content, wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF(P<0.01). Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside, deacetyl asperulosidic acid methyl ester, gardenoside and chlorogenic acid compared to cultivated GF(P<0.01). Conversely, the contents of genipin 1-gentiobioside, geniposide and genipin were significantly lower in wild GF(P<0.01). ConclusionThere are significant differences between wild and cultivated GF in terms of traits, microstructure, and contents of primary and secondary metabolites. At present, the quality evaluation system of cultivated GF remains incomplete, and this study provides a reference for guiding the production of high-quality GF medicinal materials.

Occupational chronic n-hexane poisoning incidents have been effectively curtailed in traditional printing and footwear industries, but its hazards are emerging in new industries. In recent years, two cluster incidents involving eight patients with occupational chronic n-hexane poisoning had occurred in Longgang District, Shenzhen City. Unlike the cleaning processes of electronic components in the electronics industry, these two incidents occurred during cleaning operations of non-electronic products. The rapid on-site detection tubes indicated the presence of n-hexane in the organic solvents used at the work site, and subsequent analysis of volatile components of the organic solvents further confirmed the involvement of n-hexane. Although the n-hexane exposure concentration of short term in the workplace air samples were below its occupational exposure limit, all eight cases were diagnosed as occupational chronic n-hexane poisoning, based on occupational exposure history, clinical manifestations, field investigations, and laboratory test results. These two poisoning incidents highlight that in air-conditioned or enclosed workshops with substandard occupational disease prevention facilities, the use of n-hexane containing organic solvents may result in occupational chronic n-hexane poisoning, even when the air monitoring results do not exceed the occupational exposure limits.

Objective:
To investigate the association between expression levels of potassium voltage-gated channel subfamily Q member 1 (KCNQ1) gene and gout, so as to provide the basis for diagnosis, prevention and treatment of gout.
Methods:
A total of 179 patients diagnosed with gout at the outpatient department of Guangdong Second Provincial General Hospital were enrolled in the case group, while 179 healthy individuals matched by age (within 5 years) were selected as the control group. Demographic information, lifestyle, dietary intake and biochemical blood indicators were collected through questionnaires and laboratory tests. The relative expression levels of KCNQ1 gene mRNA were quantified using real-time fluorescence quantitative PCR. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic performance of KCNQ1 gene mRNA levels in distinguishing gout. The association between the relative expression level of KCNQ1 gene mRNA and gout, the interaction effects of the relative expression levels of KCNQ1 gene mRNA with dietary intake and biochemical blood indicators on gout were analyzed using a multivariate conditional logistic regression model.
Results:
There were 112 males (62.57%) and 67 females (37.43%) in the case group, with a mean age of (41.32±10.12) years. There were 98 males (54.75%) and 81 females (45.25%) in the control group, with a mean age of (40.24±7.62) years. The mRNA expression levels of the KCNQ1 gene were higher in the case group compared to the control group (P<0.05). The area under the ROC curve was 0.897 (95%CI: 0.865-0.928). Multivariate conditional logistic regression analysis revealed that KCNQ1 gene mRNA expression levels were positively associated with gout risk (OR=1.430, 95%CI: 1.171-1.747). Significant interactions were observed between KCNQ1 mRNA expression and seafood intake (OR=2.107, 95%CI: 1.175-3.779), KCNQ1 gene mRNA expression and uric acid levels (OR=2.373, 95%CI: 1.366-4.119), as well as between uric acid levels and seafood intake (OR=2.321, 95%CI: 1.159-4.678).
Conclusion
The expression levels of the KCNQ1 gene may increase the risk of gout and further increase the risk through interaction with seafood intake and uric acid levels.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

Objective:To explore changes in the along the perivascular space (ALPS) index in patients with relapsing-remitting multiple sclerosis (RRMS) and investigate its association with cerebral injury.Methods:The study was a cross-sectional investigation. A total of 32 patients diagnosed with RRMS (RRMS group) and 30 healthy controls (HC) were retrospectively collected from March 2023 to July 2024 at the Affiliated Hospital of Inner Mongolia Medical University. All participants underwent MRI scans, including high-resolution three-dimensional (3D) T 1-weighted magnetization-prepared rapid gradient echo sequence, 3D fluid-attenuated inversion recovery sequence, and diffusion spectrum imaging. Regions of interest (ROI) were manually placed on the axial plane of the lateral ventricular body based on fractional anisotropy (FA) maps to obtain diffusion rates along the x, y, and z axes for ALPS index calculation. Tract-based spatial statistics was used to extract diffusion values from the white matter skeleton of the participants, including FA, mean diffusivity (MD), axial diffusivity (AD), radial diffusivity (RD), and quantitative anisotropy (QA). Lesion growth algorithms were employed to extract white matter lesion volume (WMLV) and number (WMLN). After lesion filling on T 1 images, brain segmentation was performed, and normalized gray matter volume (nGMV), normalized white matter volume (nWMV), and normalized cerebrospinal fluid volume (nCSFV) were obtained by normalizing with total intracranial volume(TIV). Independent sample t-tests, Mann-Whitney U tests, and χ2 tests were used to assess differences in clinical and imaging indicators between the RRMS and HC groups. Spearman′s rank correlation analysis was performed to evaluate the relationship between the ALPS index and clinical and imaging indicators. Results:The ALPS index, FA, and nGMV values were lower in the RRMS group compared to the HC group ( t=2.42, P=0.019; Z=4.85, P<0.001; t=2.56, P=0.013), while the RD value was significantly higher in the RRMS group ( Z=-2.42, P=0.015). No significant difference was found in other clinical and imaging indicators between the two groups ( P>0.05). In the RRMS group, the ALPS index was negatively correlated with WMLV ( r=-0.43, P=0.018) and positively correlated with FA ( r=0.45, P=0.012). There was no correlation between ALPS index and MD values, AD values, RD values, QA values, WLMN values, nGMV values, nMWV values, nCSFV values, TIV values, and duration of the disease ( P>0.05). Conclusions:Patients with RRMS exhibit abnormal diffusion in the perivascular spaces at the lateral ventricular body, suggesting possible glymphatic system dysfunction. The ALPS index is associated with demyelination and neurodegeneration.
