Objective: To retrospectively assess whether a lower hematocrit level (between 18% and 20%) had any impact on the safety of patients undergoing therapeutic plasma exchange (TPE), and to further determine the threshold for red blood cell supplementation prior to TPE. Methods: Clinical data from 181 adult patients who underwent TPE treatment at the Department of Blood Transfusion of our hospital from March 2023 to July 2024 were collected. The patients were divided into a study group of 44 patients (Hct ≥18% and <20%) and a control group of 137 patients (Hct≥20%). In two groups, blood volume-related safety indicators including respiration rate, heart rate, systolic blood pressure, and blood oxygen saturation levels before and after TPE were compared using t-test. Between-group differences in the grading of adverse reactions such as allergies and hypotension were analyzed using chi-square test. Results: A total of 659 TPE treatments were performed on 181 patients, with 169 TPE treatments on 44 patients in the study group (Hct≥18% and <20%) and 490 TPE treatments on 137 patients in the control group (Hct≥20%). There were no statistically significant differences in age, gender, BMI category, and the presence of cardiac insufficiency between the two groups. In the study group, there were no statistically significant differences in safety indicators such as respiration rate, heart rate, systolic blood pressure, and blood oxygen saturation level before and after TPE. In the control group, there were no statistically significant differences in heart rate and systolic blood pressure before and after TPE, but there were statistically significant differences in respiration rate and blood oxygen saturation level (P<0.05). There were no statistically significant differences in the grading of adverse reactions such as allergic reactions and hypotension between the two groups. Conclusion: For adult patients with stable conditions, maintaining a lower hematocrit level (Hct ≥18% and <20%) during TPE is relatively safe. It is feasible to lower the TPE red blood cell supplementation threshold to 18%≤Hct<20%，which may save blood resources while potentially benefit patients by avoiding unnecessary red blood cell transfusion.

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. MethodsBased on the normative documents issued by the National Health Commission, Basic Standards for Medical Record Writing and Standards for Electronic Medical Record Sharing Documents, in accordance with the Quality Management Regulations for Outpatient (Emergency) Diagnosis and Treatment Information Pages (Trial), reference to the framework of the World Health Organization Family of International Classifications (WHO-FICs), the data framework and content of rehabilitation outpatient medical records were determined, and the data standards were discussed. ResultsThis study constructed a data framework for rehabilitation outpatient medical records, including four main components: patient basic information, visit process information, diagnosis and treatment information, and cost information. Three major reference classifications of WHO-FICs, International Classification of Diseases, International Classification of Functioning, Disability and Health, and International Classification of Health Interventions,were used to establish diagnostic standards and standardized terminology, as well as coding disease diagnosis, functional description, functional assessment, and rehabilitation interventions, to improve the quality of data reporting, and level of quality control in rehabilitation. ConclusionThe structuring and standardization of rehabilitation outpatient medical records are the foundation for sharing of rehabilitation data. The using of the three major classifications of WHO-FICs is valuable for the terminology and coding of disease diagnosis, functional description and assessment, and intervention in rehabilitation outpatient medical records, which is significant for sharing and interconnectivity of rehabilitation outpatient data, as well as for optimizing the quality and safety of rehabilitation medical services.

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 investigate the clinical symptoms, laboratory tests, and treatment strategies of a case of fetal/neonatal alloimmune thrombocytopenia (FNAIT) complicated with piperacillin drug antibody. Methods: The platelet antibodies in the mother were screened and identified by ELISA. The HLA antigens of the newborn were genotyped through PCR-SSO, while the specificity of HLA antibodies in the mother was determined using a Single Antigen kit. The drug antibody was detected by a piperacillin kit. Results: Maternal antibodies against paternally-derived platelet antigens were detected. The HLA genotypes of the newborn were identified as HLA A 33∶03 and HLA B 58∶01. The mother exhibited strong positive antibodies against the specific platelet antigens of the newborn, namely anti-HLA-A33 and anti-HLA-B58 antibodies. The piperacillin antibody was detected in the newborn. Following treatment of continuous intravenous immunoglobulin (IVIG), platelet transfusions, red blood cell transfusions and discontinuation of piperacillin treatment, the platelet count and hemoglobin levels increased in the newborn. Conclusion: The newborn in this case was diagnosed with FNAIT complicated by the presence of anti-HLA-A33 and anti-HLA-B58 antibodies, as well as drug-induced hemolytic anemia caused by piperacillin drug antibody. The condition is more complicated under the influence of dual immune antibodies. Laboratory detection techniques such as platelet antibody and drug antibody tests can assist in early clinical diagnosis. At the same time, more active drug and blood transfusion treatments should be given in clinical practice to improve the prognosis.

By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.
