Ulcerative colitis is a chronic relapsing inflammatory bowel disease. Modern research indicates that immune dysregulation resulting from disruptions in circadian rhythm is closely associated with its pathogenesis. Both Western chronomedicine and traditional Chinese medicine（TCM）" treatment based on temporal factors" emphasize the temporal relationship between natural rhythms and human physiology and pathology. The " midnight-noon and ebb-flow " theory represents the concrete application and deepening of TCM " treatment based on temporal factors" within the realm of chronomedicine. This article correlates the onset time of ulcerative colitis with specific periods in the " midnight-noon and ebb-flow"theory：the Mao period（05：00-07：00），when the yangming large intestine meridian of hand is dominant； the Si period（09：00-11：00），when the taiyin spleen meridian of foot is dominant； and the You period（17：00-19：00），when the shaoyin kidney meridian of foot is dominant. According to this perspective，if the disease manifests during the Mao period，the pathogenesis is attributed to dampnessheat accumulation and disorder of qi and blood. Treatment should focus on clearing heat，resolving dampness，and harmonizing qi and blood，using modified formulas such as Shaoyao Decoction or Baitouweng Decoction. If it occurs during the Si period，the pathogenesis involves spleen deficiency with dampness obstruction and disharmony of qi and blood. Treatment should focus on strengthening the spleen，eliminating dampness，and restoring qi and blood，using modified formulas such as Huangya Decoction or Shenling Baizhu Powder. If it presents during the You period，the pathogenesis is characterized by fire failing to warm earth，and consumption resulting in qi and blood leakage. Treatment should focus on warming the kidney and spleen，and securing qi and blood，using modified formulas such as Sishen Pill or Tianhun Decoction. In addition to oral administration of Chinese herbal medicine，comprehensive therapies including acupuncture，herbal enemas，and acupoint application can provide novel insights for the clinical diagnosis and treatment of ulcerative colitis.

OBJECTIVE: To explore the genotype-phenotype correlation in a Chinese family with structural brain abnormalities due to variant of the TUBB gene. METHODS: A family undergoing prenatal diagnosis at Beijing Obstetrics and Gynecology Hospital in October 2024 was selected as the study subject. Clinical data were collected. Amniotic fluid sample was subjected to chromosomal copy number variation sequencing (CNV-seq). Trio whole-exome sequencing (Trio-WES) was carried out on the amniotic fluid and parental blood samples, and candidate variant was verified by Sanger sequencing. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: 2023-KY-076-01). RESULTS: Both prenatal ultrasound and fetal MRI showed deviation of brain midline, unilateral lateral ventriculomegaly, and bilateral gyral asymmetry. Trio-WES revealed that the fetus has harbored a maternally derived heterozygous missense variant of the TUBB gene [NM_178014.4: c.155A>G (p.N52S)]. Sanger sequencing confirmed that the woman and a previously terminated fetus both harbored the same variant. Both the proband and two fetuses exhibited similar neuroimaging abnormalities including midline deviation and asymmetrical gyri. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as likely pathogenic (PM2_Supporting+PS2_Moderate+PS3). CONCLUSION The heterozygous c.155A>G (p.N52S) variant was the TUBB gene probably underlay the pathogenesis of the structural brain abnormalities in this family. Above findings have expanded the phenotypic spectrum associated with the variant and facilitated the prenatal diagnosis for this family.

Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

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.

ObjectiveTo explore the data standard system of electronic medical records in the field of rehabilitation, focusing on the terminology and coding standards, data structure, and key content categories of rehabilitation electronic medical records. MethodsBased on the Administrative Norms for the Application of Electronic Medical Records issued by the National Health Commission of China, the electronic medical record standard architecture issued by the International Organization for Standardization and Health Level Seven (HL7), the framework of the World Health Organization Family of International Classifications (WHO-FICs), Basic Architecture and Data Standards of Electronic Medical Records, Basic Data Set of Electronic Medical Records, and Specifications for Sharing Documents of Electronic Medical Records, the study constructed and organized the data structure, content, and data standards of rehabilitation electronic medical records. ResultsThe data structure of rehabilitation electronic medical records should strictly follow the structure of electronic medical records, including four levels (clinical document, document section, data set and data element) and four major content areas (basic information, diagnostic information, intervention information and cost information). Rehabilitation electronic medical records further integrated information related to rehabilitation needs and characteristics, emphasizing rehabilitation treatment, into clinical information. By fully applying the WHO-FICs reference classifications, rehabilitation electronic medical records could establish a standardized framework, diagnostic criteria, functional description tools, coding tools and terminology index tools for the coding, indexing, functional description, and analysis and interpretation of diseases and health problems. The study elaborated on the data structure and content categories of rehabilitation electronic medical records in four major categories, refined the granularity of reporting rehabilitation content in electronic medical records, and provided detailed data reporting guidance for rehabilitation electronic medical records. ConclusionThe standardization of rehabilitation electronic medical records is significant for improving the quality of rehabilitation medical services and promoting the rehabilitation process of patients. The development of rehabilitation electronic medical records must be based on the national and international standards. Under the general electronic medical records data structure and standards, a rehabilitation electronic medical records data system should be constructed which incorporates core data such as disease diagnosis, functional description and assessment, and rehabilitation interventions. The standardized rehabilitation electronic medical records scheme constructed in this study can support the improvement of standardization of rehabilitation electronic medical records data information.

ObjectiveTo analyze the data structure and standards of rehabilitation outpatient medical records, to provide data support for improving the quality of rehabilitation outpatient care and developing medical insurance payment policies.

ObjectiveTo explore the standardization of inpatient rehabilitation medical record summary sheet, encompassing its structure, content and data standards, to enhance the standardization level of inpatient rehabilitation medical record summary sheet, improve data reporting quality, and provide accurate data support for medical insurance payment, hospital performance evaluation, and rehabilitation discipline evaluation. MethodsBased on the relevant specifications of the National Health Commission's Basic Norms for Medical Record Writing, Specifications for Sharing Documents of Electronic Medical Records, and Quality Management and Control Indicators for Inpatient Medical Record Summary Sheet (2016 Edition), this study analyzed the structure and content of the inpatient rehabilitation medical record summary sheet. The study systematically applied the three major reference classifications of the World Health Organization Family of International Classifications, International Classification of Diseases (ICD-10/ICD-11, ICD-9-CM-3), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), for disease diagnosis, functional description and assessment, and rehabilitation intervention, forming a standardized terminology system and coding methods. ResultsThe inpatient rehabilitation medical record summary sheet covered four major sections: inpatient information, hospitalization information, diagnosis and treatment information, and cost information. ICD-10/ICD-11 were the standards and coding tools for admission and discharge diagnoses in the inpatient rehabilitation medical record summary sheet. The three functional assessment tools recommended by ICD-11, the 36-item version of World Health Organization Disability Assessment Schedule 2.0, Brief Model Disability Survey and Generic Functioning domains, as well as ICF, were used for rehabilitation functioning assessment and the coding of outcomes. ICHI Beta-3 and ICD-9-CM-3 were used for coding surgical procedures and operations in the medical record summary sheet, and also for coding rehabilitation intervention items. ConclusionThe inpatient rehabilitation medical record summary sheet is a summary of the relevant content of the rehabilitation medical record and a tool for reporting inpatient rehabilitation data. It needs to be refined and optimized according to the characteristics of rehabilitation, with necessary data supplemented. The application of ICD-11/ICD-10, ICF and ICHI Beta-3/ICD-9-CM-3 classification standards would comprehensively promote the accuracy of inpatient diagnosis of diseases and functions. Based on ICD-11 and ICF, relevant functional assessment result data would be added, and ICHI Beta-3/ICD-9-CM-3 should be used to code rehabilitation interventions. Improving the quality of rehabilitation medical records and inpatient rehabilitation medical record summary sheet is an important part of rehabilitation quality control, and also lays an evidence-based data foundation for the analysis and application of inpatient rehabilitation medical record summary sheet.

Objective To explore the mechanism of total saponin from Panax japonicus(TSPJ)in alleviating neuroinflammation in experimental autoimmune encephalomyelitis(EAE)based on the activation of microglia mediated by MAPK signaling pathway.Methods In vivo experiments,mice were divided into normal group,model group and TSPJ low-and high-dosage groups.EAE mouse model was induced by myelin oligodendrocyte glycoprotein polypeptide.Each medication group was gavaged with corresponding drug solution once a day for 28 days.The number of Iba-1-positive cells was assessed using immunofluorescence,the protein expressions of tumor necrosis factor-α(TNF-α),interleukin(IL)-6,IL-1β and MAPK signaling pathway related factors were detected by Western blot.In vitro experiments,murine microglia BV2 were divided into normal group,model group and TSPJ low-and high-dosage groups.LPS+IFN-γ was used to induce M1 polarization of BV2 cells,medication groups were given TSPJ intervention,the content of nitric oxide(NO)in cell supernatant,the expression of M1 microglia markers and MAPK signaling pathway related factors were detected,and ERK and JNK signaling pathway inhibitors were further used to clarify the molecular mechanism of TSPJ antagonizing neuroinflammation.Results The results of in vivo experiments showed that compared with the normal group,the cell body and number of microglia in cerebral cortex of the model group mice increased significantly(P<0.01),and the protein expressions of TNF-α,IL-6,IL-1β,p-p38/p38,p-JNK/JNK,p-ERK1/2/ERK1/2 significantly increased(P<0.05,P<0.01);compared with the model group,the number of microglia in cerebral cortex of TSPJ low-and high-dosage groups significantly decreased(P<0.01),the expressions of TNF-α,IL-6,p-p38/p38,p-JNK/JNK,p-ERK1/2/ERK1/2 protein significantly decreased(P<0.05,P<0.01),and the expression of IL-1β protein in TSPJ high-dosage group significantly decreased(P<0.05).The results of in vitro experiments showed that compared with the normal group,the content of NO in cell supernatant of the model group significantly increased(P<0.01),the protein expressions of CD16,CD86,p-p38/p38,p-JNK/JNK,p-ERK1/2/ERK1/2 significantly increased(P<0.01);compared with the model group,the content of NO in cell supernatant of TSPJ low-and high-dosage groups significantly decreased(P<0.01),and the protein expressions of CD16,CD86,p-p38/p38,p-JNK/JNK,p-ERK1/2/ERK1/2 significantly decreased(P<0.05,P<0.01).TSPJ combined with ERK and JNK pathway inhibitors could further inhibit the expressions of TNF-α and IL-6,but there was no significant difference compared with inhibitors alone.Conclusion TSPJ can inhibit the activation of microglia by regulating MAPK signaling pathway,thereby reducing EAE induced central nervous inflammation.

Objective:To characterize and compare the polysaccharide components of Panax japonicus with its common counterfeits (Dysosma versipellis, Lycopus lucidus and Dysosma pleiantha); To provide a scientific basis for the quality evaluation of polysaccharides of Panax japonicu.Methods:Crude polysaccharides were extracted using water and subsequently precipitated with ethanol. Three batches of total polysaccharides from Panax japonicus, Dysosma versipellis, Lycopus lucidus and Dysosma pleiantha were prepared using the savage deproteinization method. The molecular weight distribution, functional group characteristics and monosaccharide composition of each batch were analyzed using high performance gel filtration chromatography (HPGFC), fourier-transform infrared spectroscopy (FT-IR) and derivatization of 1-phenyl-3-methyl-5-pyrazolinone with high performance liquid chromatography (PMP-HPLC). Using DEAE column chromatography purification and specific enzymolysis, combined with high performance thin layer chromatography and carbohydrate gel electrophoresis, the saccharide profiles of polysaccharides of Panax japonicus and its counterfeits were analyzed and compared.Results:The molecular weight distribution of total polysaccharides from three batches of Panax japonicus exhibited high similarity, with a concentrated distribution ranging from 2.05×10 4 - 1.87×10 3 Da. However, the molecular weight distribution of total polysaccharides from Dysosma versipellis was scattered in regions 5.08×10 6-6.47×10 5 Da and 6.47×10 5-2.05×10 4 Da, while Lycopus lucidus and Dysosma pleiantha was scattered in regions 6.47×10 5-2.05×10 4 Da and 2.05×10 4-1.87×10 3 Da; the infrared spectra of all samples exhibited similarity, indicating that the sugar chains of each polysaccharide were predominantly linked by α-glycosidic bonds, with no significant differences was observed. In terms of monosaccharide composition, the polysaccharides from Panax japonicus, Dysosma versipellis and Dysosma pleiantha were mainly composed of glucose, galactose, arabinose, galacturonic acid, rhamnose and mannose. In contrast, the polysaccharides from Lycopus lucidus were distinct, primarily consisting of galactose and glucose; glycosidic linkage analysis revealed that the polysaccharides purified by DEAE column chromatography from Panax japonicus and its counterfeits were resistant to hydrolysis by β- galactosidase, but could be hydrolyzed by α-amylase and pectinase (except for Lycopus lucidus). The oligosaccharides produced by α-amylase hydrolysis of three batches of Panax japonicus polysaccharides were similar, showing clear differences from those of the counterfeits. The results of pectinase hydrolysis were correlated with the content of uronic acids. Conclusions:The total polysaccharides from Panax japonicus, Dysosma versipellis, Lycopus lucidus and Dysosma pleiantha exhibit significant differences in their molecular weight distributions. The monosaccharide composition of Lycopus lucidus polysaccharides is notably distinct, making it easily distinguishable from other species; purification using DEAE column chromatography, combined with HPTLC and polysaccharide analysis using carbohydrate gel electrophoresis (PACE), effectively differentiates the polysaccharides of Panax japonicus from its counterfeits. This approach provides a valuable reference for the quality analysis of polysaccharides in TCM. Additionally, it lays a foundation for the development and utilization of Panax japonicus polysaccharides.

Objective:To evaluate preoperative high-resolution thin-layer cervical enhanced CT used to predict the venous route of the submental flap reflux vein and its relationship with adjacent structures in order to guide the anatomical understanding and protection of submental flap in pharyngeal cancer surgery.Methods:Sixty consecutive patients with pharyngeal cancer who underwent submental flap repair surgery in our department from March 2022 to December 2024, as well as 60 patients who were accepted neck dissection suffering other cancers, were selected. Before surgery, high-resolution cervical enhanced CT scans were performed, and the position of the transverse section of the facial vein in the venous phase horizontal image gradually variation tendency was focused layer by layer. The direction and adjacent relationship of the submental flap reflux veins were determined and recorded. Combined with 60 patients with other head and neck tumors who underwent neck dissection in our department during the same period (a total of 120 cases, 240 sides), the classification and management of the draining veins of Fang′s mental flap were conducted. Type Ⅰ mainly drains into the internal jugular vein; Type Ⅱ mainly drains into the external jugular vein and Type Ⅲ mainly drains into the anterior jugular vein (often accompanied by an external jugular draining branch). The status and proportion of venous drainage were analyzed.Results:Vascular predictive coincidence rate was 98.3% (59/60) among the 60 patients with pharyngeal cancer. Only one patient was predicted to have a simple return to the external jugular vein. However, during the operation, in addition to the main return to the external jugular vein, a small portion also returned to the internal jugular vein. Submental flap reflux vessels were classified into three types based on intraoperative submental flap venous return in 60 cases of laryngopharyngeal cancer, in conjunction with the analysis of venous return patterns from 240 cervical CT scans. Type Ⅰ mainly refluxed to the internal jugular vein, accounting for 42.1%. Type Ⅱ mainly refluxed to the external jugular vein (47.9%). Type Ⅲ mainly refluxed to the anterior jugular vein (10.0%). The total detection rate of CT reading of 240 venous reflux was 98.7% (237/240). Vascular predictive coincidence rate was 97.9%(235/240).Conclusion:The detailed analysis of submental venous return vessels can accurately predict the direction of reflux veins and its surrounding areas by preoperative high-resolution enhanced CT scan. This provides reliable guidance for the anatomy and protection of the submental flap reflux veins during surgery.
