The purpose of this paper is to explore the decoction and dosing methods of rhubarb root and rhizome in classical prescriptions and to provide a reference basis for the clinical use of rhubarb root and rhizome. By collating the relevant classical prescriptions of rhubarb root and rhizome in Shanghan Lun and Jingui Yaolüe, the relationship between its decoction and dosing methods and the syndrome was analyzed. The decoction of rhubarb root and rhizome in classical prescriptions can be divided into three categories: simultaneous decoction, decoction later, and other methods (impregnation in Mafei decoction, decoction with water from the well spring first taken in the morning, and pills). If it enters the blood level or wants to slow down, rhubarb root and rhizome should be decocted at the same time with other drugs. If it enters the qi level and wants to speed up, rhubarb root and rhizome should be decocted later. If it wants to upwardly move, rhubarb root and rhizome should be immersed in Mafei decoction. If it wants to suppress liver yang, rhubarb root and rhizome should be decocted with water from the well spring first taken in the morning. If the disease is prolonged, rhubarb root and rhizome should be taken in pill form. The dosing methods of rhubarb root and rhizome can be divided into five categories: draught, twice, three times, before meals, and unspecified. For acute and serious illnesses with excess of pathogenic qi and adequate vital qi, we choose draught. For gastrointestinal diseases, we choose to take the medicine twice. For achieving a moderate and long-lasting effect, we choose to take the medicine three times. If the disease is located in the lower part of the heart and abdomen, we choose to take it before meals. The use of rhubarb root and rhizome in clinical practice requires the selection of the appropriate decoction and dosing methods according to the location of the disease, the severity of the disease, the patient′s constitution, and the condition after taking the medicine.

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.

" Lijie and yellowish sweating" originates from the chapter on stroke and arthralgia diseases in Synopsis of Golden Chamber. Later generations typically interpret it as yellow fluid oozing from painful joints, a characteristic manifestation of arthralgia. In Western medicine, Lijie corresponds to diseases such as gouty arthritis, with its primary clinical manifestations being redness, swelling, heat, and painful joints, most often without yellow fluid discharge. Therefore, the interpretation of " Lijie and yellowish sweating" contradicts the clinical manifestations often observed in this disease. Thus, this article reinterprets the meaning of " Lijie and yellowish sweating" from the pathogenesis of " sweat exposure to water, as if water harms the heart" , combined with the viewpoints of other medical practitioners. Determining the meaning of " yellowish sweating" is crucial for understanding the pathogenesis of arthralgia and clarifying the relationship between arthralgia and yellowish sweating. ZHANG Zhongjing mentioned arthralgia and " yellowish sweating" together, not to differentiate between the two diseases but to emphasize the common pathogenesis of the two, namely, the cold and dampness injuring the heart, blood, and vessels. This paper proposes a new explanation of " Lijie and yellowish sweating" , which suggests that " yellowish sweating" is not confined to the joints but can be found all over the body. The pathogenesis of " Lijie and yellowish sweating" lies in the insufficiency of the liver and kidney and exogenous water dampness, leading to disharmony between nutrient qi and defensive qi and between yin and yang. Primary treatment should harmonize yingfen and weifen, as well as tonify and replenish the liver and kidney. The clinical selection of medicines can be considered Guizhi Decotion, a type of formula. The pathogenesis of " Lijie and yellowish sweating" is complex, and clinical treatment should be comprehensively considered to achieve the best therapeutic effect.

ObjectiveTo investigate the effect of Liuwei Dihuangwan drug-containing serum （LDP） on epithelial-mesenchymal transition （EMT） and the expression of cancer stem cell （CSC） properties in 4T1 cells from triple-negative breast cancer by intervening myeloid-derived suppressor cells （MDSCs）. MethodsSPF-grade female SD rats were randomly divided into three groups， which were given 0.39， 1.94， 3.89 g·kg^-1·d^-1 suspension of Liuwei Dihuangwan for 7 days， respectively， to prepare low-， medium-， and high-dose LDPs. 4T1 cells were inoculated subcutaneously into the mammary glands of SPF-grade female Balb/c mice to construct a transplantation tumor model. Bone marrow cells were extracted from the tibia and femur and induced into MDSCs in vitro. The cell counting kit-8 （CCK-8） assay was used to detect the viability of 4T1 cells and MDSCs. The number of MDSCs and the expressions of CSC surface markers CD44 and CD24 in 4T1 cells were detected by flow cytometry （FC）. The migration， invasion， and proliferation of 4T1 cells were detected by cell scratch assay， Transwell invasion assay， and plate colony-forming assay， respectively. Western blot （WB） was used to detect the protein expression of transforming growth factor-β （TGF-β）， nuclear factor-κB （NF-κB）， C-X-C motif chemokine ligand 2 （CXCL2）， E-cadherin， and N-cadherin. The expression of EMT-related proteins E-cadherin and N-cadherin were detected by immunofluorescence （IF）. ResultsCompared with the normal group， LDP showed no significant inhibitory effect on the cell viability of 4T1 cells， but it significantly reduced the viability and number of MDSCs and reduced the number of MDSCs， as well as the expression of TGF-β （P<0.05， P<0.01）. The migration， invasion， and proliferation of 4T1 cells were increased after co-culture with MDSCs （P<0.05， P<0.01）. The expressions of NF-κB， CXCL2， and N-cadherin and the proportion of CSC （CD44⁺CD24^-） were elevated （P<0.05， P<0.01）， while the expression of E-cadherin was decreased （P<0.05）. After the intervention of MDSCs with LDP， followed by co-culture with 4T1 cells， the migration， invasion， and proliferation of 4T1 cells were obviously reduced （P<0.01）. The expressions of NF-κB， CXCL2， and N-cadherin were decreased （P<0.05， P<0.01）， and the expression of E-cadherin was increased （P<0.05， P<0.01）. There was no statistical difference in the proportion of CSC （CD44⁺CD24^-） in 4T1 cells. However， the proportion of CSC （CD44⁺CD24^-） was decreased in the co-culture system of 4T1 cells and MDSCs with LDP intervention （P<0.05， P<0.01）. ConclusionLDP can reduce the viability and number of MDSCs and the expression of TGF-β， NF-κB， and CXCL2， reverse EMT， and reduce the characteristic expression of CSC to inhibit the migration， invasion， and proliferation of 4T1 cells.

ObjectiveTo investigate the content of trihalomethanes (THMs) in treated water after different water treatment processes and their correlations with premanganate index, so as to provide data support for the renovation of water production process and optimization of water quality improvement. MethodsFrom 2022 to 2023, seven centralized water supply units using raw water from Qingcaosha reservoir were selected as the testing sites, among which three units with the conventional treatment process, two units with the advanced treatment process, and two units with the advanced treatment process combined CO₂ treatment. Monthly water quality testing data were collected, focusing on testing the concentration variations of THMs, trichloromethane, dibromochloromethane, bromodichloromethane, bromoform, and permanganate index. ResultsThe comparison between conventional treatment process and advanced treatment process demonstrated that the conventional treatment process exhibited significantly higher concentrations of trihalomethanes, trichloromethane, bromodichloromethane, and permanganate index in water samples (all P<0.05). When comparing conventional treatment process with advanced treatment process combined with carbon dioxide treatment, the conventional treatment process showed significantly elevated levels of trihalomethanes, dibromochloromethane, bromodichloromethane, and permanganate index (all P<0.05). No statistically significant differences were observed in the comparison of various indicators between advanced treatment process and advanced treatment process combined with carbon dioxide treatment for any of the measured parameters (all P>0.05). Analysis of seasonal variations revealed that finished water during the high-temperature period (May to November) contained significantly higher concentrations of trihalomethanes, trichloromethane, bromodichloromethane, and tribromomethane compared to the low-temperature period (December to April of the following year) (all P<0.05). Significant positive correlations were identified between permanganate index and trihalomethanes (r=0.213, P=0.007), permanganate index and dibromochloromethane (r=0.186, P=0.019), permanganate index and bromodichloromethane (r=0.243, P=0.002), permanganate index and tribromomethane (r=0.193, P=0.014). ConclusionCompared to the conventional water treatment process, advanced treatment process and advanced treatment combined with CO₂ injection process can significantly reduce the concentrations of THMs in the treated effluent water. Besides, the generation of THMs is affected by seasonal temperatures, with higher concentrations of THMs, trichloromethane, bromodichloromethane, and bromoform being observed in the high-temperature season. Additionally, the permanganate index shows a significant positive correlation with THMs concentrations, indicating that the content of organic matter in the source of raw water contributes to the generation of THMs in the treated water.

Objective: To investigate the accuracy of the mandibular curve of Spee and mandibular curve of Wilson curve, mandibular posterior crown inclination, maxillary and mandibular arch width, and mandibular incisor labial inclination changes in the invisible orthodontic treatment of extracted and non-extracted patients to provide a basis for the study of the therapeutic efficacy of the invisible aligner. Methods: This study was approved by the Unit Medical Ethics Committee. Adult bony Class I patients treated with invisible aligners between 2016 and 2023 were selected and categorized into 32 cases in a group with four first premolar extractions and 33 cases in a non-extraction group. The initial scanning model (T1), the orthodontic plan design model (T2), and the scanning model after alignment and leveling (T3) were collected, and the scanning data at different time points were exported to STL format files. They were then analyzed and measured using GOM Inspect 2019 software; the clinical effect (T1-T3) was defined as AC, and the expected result (T1-T2) was defined as CC. To explore the mandibular curve of Spee, the leveling accuracy of the mandibular Wilson curve (AC/CC×100%), the change in mandibular posterior crown inclination, the change in maxillary and mandibular arch width and the change in mandibular incisor labial inclination. The results were tallied using R4.3.2 software. Results: The leveling accuracy of the mandibular curve of Spee was 3.2% and 10.1% in the extraction and non-extraction groups, respectively; the leveling accuracy of the mandibular first molar in the extraction and non-extraction groups was 9.5% and 4.2%, respectively, and the leveling accuracy of the mandibular second premolar was 32.8% and 25%, respectively. The leveling accuracy of the mandibular curve of Wilson was 126% in the extraction group compared to 704% in the non-extraction group. The maximum values of AC for crown inclination of the mandibular posterior teeth were all found in the first molar and the minimum values in the second premolar (P< 0.05); CC was the greatest in the second premolar and the least in the first molar in the extraction group (P< 0.05), and in the second molar and the least in the second premolar in the non-extraction group (P< 0.05). There was no significant difference in the change of maxillary and mandibular arch widths in the extraction group (P> 0.05); the AC of the arch widths at the maxillary first molar and at the mandibular second premolar and first molar in the non-extraction group was significantly greater than the CC (P< 0.05). The AC of the mandibular second premolar crown inclination was significantly greater in the non-extraction group than in the extraction group (P < 0.05), showing a more pronounced buccal inclination of the crowns; in contrast, there was no significant difference between the mandibular molar crown inclination AC and CC in the two groups (P > 0.05). The CC of mandibular curve of Spee in the extraction group was significantly greater than that in the non-extraction group (P < 0.05), whereas there was no significant difference in AC between the two groups (P > 0.05). In addition, the AC of the labial inclination of the mandibular incisors in the extraction group and the non-extraction group was smaller than the CC, but both were positive, indicating an increase in the degree of labial inclination of the mandibular incisors. Conclusion The invisible aligner mandibular curve of Spee leveling was poorly expressed, and there was a tendency for overexpression of the mandibular curve of Wilson leveling. Increased labial inclination of the mandibular incisors was observed in patients. The extraction group was accurately predicted in arch width control, there was overexpansion in the non-extraction group.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

BACKGROUND: Death burden of stroke is severe with over one-third rural residents in China, but there is still a lack of specific national and high-quality reports on the urban-rural differences in stroke burden, especially for subtypes. We aimed to update the understanding of urban-rural differences in stroke deaths. METHODS: This is a descriptive observational study. Data from the national mortality surveillance system, which covers 323.8 million with 605 disease surveillance points (DSPs) across all 31 provinces, municipalities, and autonomous regions in China. All deaths from stroke as the underlying cause from 2015 to 2020 according to DSPs. Crude mortality rate and age-standardized mortality rate (ASMR) were estimated through DSPs. Average annual percentage change was used to explain the change in mortality rate. RESULTS: From 2015 to 2020, the majority of deaths from all stroke subtypes occurred in rural areas. There were significant differences between the changes of urban and rural ASMRs. On the whole, the changes in urban areas were evidently better, and the ASMR differences were basically expanding. Stroke ASMR in urban China decreased by 15.5%. The rural ASMR of ischemic stroke increased by 12.9%. The rural and urban ASMRs of intracerebral hemorrhage decreased by 24.9% and 27.4%, and those of subarachnoid hemorrhage decreased by 29.5% and 40.4%, respectively. The highest ASMRs of all stroke subtypes and the increasing trend of ischemic stroke ASMR make rural males the focus of stroke management. CONCLUSIONS The death burden of stroke varies greatly between urban and rural China. Rural residents face unique challenges.

Background/Aims: Liver transplantation is the most effective treatment for the sickest patients with acute-on-chronic liver failure (ACLF). However, the influence of donor age on liver transplantation, especially in ACLF patients, is still unclear. Methods: In this study, we used the data of the Scientific Registry of Transplant Recipients. We included patients with ACLF who received liver transplantation from January 1, 2007, to December 31, 2017, and the total number was 13,857. We allocated the ACLF recipients by age intogroup I (donor age ≤17 years, n=647); group II (donor age 18–59 years, n=11,423); and group III (donor age ≥60 years, n=1,787). Overall survival (OS), graft survival, and mortality were com-pared among the three age groups and the four ACLF grades. Cox regression was also analyzed. Results: The 1-, 3-, and 5-year OS rates were 89.6%, 85.5%, and 82.0% in group I; 89.4%, 83.4%, and 78.2% in group II; and 86.8%, 78.4%, and 71.4% in group III, respectively (p<0.001).When we analyzed the different effects of donor age on OS with different ACLF grades, in groupsII and III, we observed statistical differences. Finally, the cubic spline curve told us that the relative death rate changed linearly with increasing donor age. Conclusions Donor age is related to OS and graft survival of ACLF patients after transplanta-tion, and poorer results were associated with elderly donors. In addition, different donor ages have different effects on recipients with different ACLF grades.
