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 retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective To investigate the protective effect of curcumin (Cur) against arsenic-induced neuroimmune toxicity and the underlying molecular mechanisms in vivo. Methods Eighty SPF female C57BL/6 mice were randomly assigned to four groups: a control group, an arsenic-treated group, a Cur-treated group and an arsenic+Cur group, with 20 mice in each group. The control group received distilled water; the arsenic-treated group was given 50 mg/L NaAsO2 in the drinking water; the Cur-treated group was gavaged with 200 mg/kg of curcumin for 45 days; and the arsenic+Cur group received distilled water and was gavaged with 200 mg/kg of curcumin. Y-maze and Morris water maze experiments were conducted to assess the learning and memory ability of the mice. Western blot analysis was used to detect protein levels of blood-brain barrier tight junction proteins zonula occludens protein 1(ZO-1) and claudin 5, T lymphocyte subpopulation CD4 and CD8, Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway-related molecules JAK2 and STAT3. Real-time PCR was used to assess the mRNA levels of CD4+ T lymphocyte subsets type 1 T helper (Th1), Th2, Th17 and regulatory T cells (Treg) transcription factors and cytokines in hippocampus. Results Compared with the control group, the arsenic-treated group showed a significantly decreased correct rate, increased latency to reach the platform on the third and fifth days, and reduced times of crossing the platform. The expression of ZO-1 and claudin 5 protein decreased significantly, and the protein levels of CD4 and CD8 were up-regulated. The mRNA levels of Th1, Th17, and Treg transcription factor T-box expressed in T cell(T-bet), retinoid-related orphan receptor gamma t(RORγt), and forkhead box protein 3(FOXP3) in the arsenic-treated group were decreased. Th1 and Th17 cytokines interferon γ(IFN-γ) and interleukin 17(IL-17) were markedly decreased. In contrast, the mRNA levels of the Th2 transcription factor GATA binding protein 3(GATA3) and cytokine IL-4 in arsenic-treated group were higher than those in the control group. Furthermore, the protein levels of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) increased. Compared with the arsenic-treated group, the arsenic+Cur group demonstrated a significantly increased correct rate, decreased latency to reach the platform on the third and fifth days, and increased times of crossing the platform. The protein expression levels of ZO-1 and claudin 5 increased significantly, and the protein levels of CD4 and CD8 were down-regulated. The mRNA levels of Th2 transcription factor GATA3 and cytokine IL-4 were decreased. The mRNA levels of Th17 transcription factor RORγt and cytokine IL-17 were markedly increased. Furthermore, the protein levels of p-JAK2 and p-STAT3 decreased. Conclusion Through inhibiting the JAK2/STAT3 signaling pathway, curcumin could improve arsenic-induced decline in learning and memory abilities in mice, reverse the destruction of blood-brain barrier permeability of innate immune system components in arsenic-exposed mice, and antagonize arsenic-induced increase in the number of renal CD4 and CD8 molecule as well as the imbalance of CD4+ T lymphocyte subsets (Th1, Th2, Th17 and Treg), ultimately counteracting arsenic-induced neurotoxicity.

【Objective】 To explore the effect of recovery autologous blood transfusion combined with bilateral internal iliac artery presetting in high-risk patients with hemorrhage during cesarean section. 【Methods】 A total of 162 high-risk patients with hemorrhage who underwent cesarean section from January 2021 to May 2023 in our hospital were prospectively selected and divided into in Groups A, B, and C with 54 cases in each group according to the indications for the method of transfusion. Group A received allogeneic blood transfusion, Group B received autologous blood transfusion, Group C received autologous blood transfusion combined with bilateral internal iliac artery balloon presetting. 【Results】 Intraoperative blood loss (mL) (1 600 vs 1 500 vs 800), postoperative hospital stay(d) (7 vs 7 vs 6) and operative time(min) (107 vs 104.50 vs 77) in group C were all lower than those in group A and B (P<0.05), with no difference between group A and B (P>0.05); The autologous blood transfusion volume(mL) in group C was lower than that in group B (525.5 vs 261, P<0.05). The proportion of allogeneic erythrocytes in group C was lower than that in group A (22.22% vs 100.00%, P<0.016 7). The proportion of plasma in group C was lower than that in groups A and B (18.50% vs 66.70%/18.50% vs 44.40%, P<0.016 7). The incidence of coagulating dysfunction in group C was lower than that in group A (7.41% vs 25.93%, P<0.016 7). The incidence of hysterectomy in group C was lower than that in group A (1.85% vs 16.67%, P<0.016 7), and there was no difference between group A and B (16.67% vs 11.11%, P>0.016 7). 【Conclusion】 Recovery autologous blood transfusion combined with bilateral internal iliac artery balloon presetting in cesarean section for high-risk patients with hemorrhage achieved ideal effects, which can significantly reduce intraoperative blood loss, intraoperative autologous blood transfusion, allogeneic red blood cells and plasma transfusion, as well as the operation time and postoperative hospital stay. In addition, it can improve the coagulation function and hysterectomy, which is conducive to ensuring the safety of maternal and promoting early rehabilitation, and preserving the fertility of patients to a certain extent, which is worthy of further clinical promotion.
