ObjectiveFor prepubertal and urgently treated malignant tumor patients, ovarian tissue cryopreservation and transplantation represent more appropriate fertility preservation methods. Current clinical practices often involve freezing ovarian tissue with high concentrations of cryoprotectants (CPAs) and thawing with water baths. These processes lead to varying degrees of toxicity and devitrification damage to ovarian tissue. Therefore, this paper proposes optimized methods for vitrification of ovarian tissues based on sodium alginate hydrogel encapsulation and magnetic induction nanowarming technology. MethodsFirstly, the study investigated the effects of sodium alginate concentration, the sequence of hydrogel encapsulation and CPAs loading on vitrification efficiency of encapsulated ovarian tissue. Additionally, the capability of sodium alginate hydrogel encapsulation to reduce the required concentration of CPAs was validated. Secondly, a platform combining water bath and magnetic induction nanowarming was established to rewarm ovarian tissue under various concentrations of magnetic nanoparticles and magnetic field strengths. The post-warming follicle survival rate, antioxidant capacity, and ovarian tissue integrity were evaluated to assess the efficacy of the method. ResultsThe study found that ovarian tissue encapsulated with 2% sodium alginate hydrogel exhibited the highest follicle survival rate after vitrification. The method of loading CPAs prior to encapsulation proved more suitable for ovarian tissue cryopreservation, effectively reducing the required concentration of CPAs by 50%. A combination of 8 g/L Fe3O4 nanoparticles and an alternating magnetic field of 300 Gs showed optimal warming effectiveness for ovarian tissue. Combining water bath rewarming with magnetic induction nanowarming yielded the highest follicle survival rate, enhanced antioxidant capacity, and preserved tissue morphology. ConclusionSodium alginate hydrogel encapsulation of ovarian tissue reduces the concentration of CPAs required during the freezing process. The combination of magnetic induction nanowarming with water bath provides an efficient method ovarian tissue rewarming. This study offers novel approaches to optimize ovarian tissues vitrification.

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.

Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia (FD), this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes, postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS, whereas local acupoints alone may be more suitable for EPS. Additionally, the study explores the impact of various factors, such as stimulation techniques, needling order, intensity or stimulation parameters, and depth, on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations, local versus distal, affect the treatment outcomes of FD subtypes, providing new insights for clinical acupuncture prescriptions.

ObjectiveTo evaluate the impact of narrative medicine education on the narrative ability of resident physicians undergoing standardized residency training, and to explore its application value in clinical practice. MethodsA total of 23 obstetricians and gynecologists who participated in residency training at the Fourth Hospital of Hebei Medical University from October 2021 to June 2024 were randomly selected to receive a 3-month residency training program integrated with narrative medicine education, including narrative theory learning, text reading, reflective writing, and scenario-based case analysis. A questionnaire survey was conducted to analyze the personal situation of resident physicians, their narrative ability before and after receiving narrative medicine education, and their satisfaction with teaching. ResultsThe results of the questionnaire survey showed that resident physicians who had received narrative medicine education scored higher on the narrative ability assessment scale than before training, including improved narrative abilities in the dimensions of life and health narrative awareness, professional narrative thinking, professional development narrative behavior, peer communication narrative behavior, and doctor-patient interaction narrative behavior (P<0.05). However, there were no statistically significant differences in the dimensions of life and health narrative behavior and family connection narrative behavior (P>0.05). Meanwhile, resident physicians’ interest in active learning, clinical thinking ability, doctor-patient communication ability, and satisfaction with teaching methods have also been improved (P<0.05). ConclusionNarrative medicine education can effectively enhance the narrative ability of resident physicians and make up for the current deficiencies in humanistic literacy and ethical education in current medical education. It is of great significance for improving doctor-patient relationships and the quality of medical services. Therefore, it is recommended to integrate narrative medicine education into the regular training curriculum for resident physicians.

ObjectiveTo study the effect of the herb pair Mori Folium-Ginseng Radix et Rhizoma (HMG) on glucose and lipid metabolism in the mouse model of type 2 diabetes mellitus and decipher the possible treatment mechanism. MethodsThe db/db mice were chosen as the mouse model of type 2 diabetes mellitus and then treated with HMG at low and high doses (1.56, 3.12 g∙kg-1, respectively) or metformin (0.26 g∙kg-1) by gavage for 6 weeks. The normal group and the model group were treated with double distilled water at the same time according to body weight. The 8-h fasting blood glucose and body weight were measured once a week. The oral glucose tolerance test (OGTT) was conducted at the 6th week of dosing. The mice were sacrificed after the end of dosing. Serum levels of lipids [total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL)], liver function indicators [aspartate aminotransferase (AST) and alanine aminotransferase (ALT)], non-esterified fatty acids (NEFA), glycosylated serum protein (GSP), serum glucose (GLU), fasting insulin (FINS), and renal function indicators [creatinine (Crea) and blood urea nitrogen (BUN)] were measured by enzyme-linked immunosorbent assay. The protein levels of peroxidase proliferator-activating receptor gamma (PPARγ), acetyl coenzyme A carboxylase (ACC), and sterol regulatory element-binding protein-1 (SREBP-1) were determined by Western blot. The pathological changes in the liver and pancreas were examined. ResultsCompared with the normal group, the model group presented increased body weight, elevated levels of blood glucose, TG, TC, AST, ALT, GLU, NEFA, GSP, and HDL-C, up-regulated protein levels of ACC and SREBP-1, and down-regulated protein level of PPARγ (P<0.01). Meanwhile, the model group presented a large amount of lipid droplets and steatosis in the liver, as well as karyopyknosis and lymphocyte infiltration in the pancreas. Compared with the model group, the high- and low-dose HMG groups showed decreased body weight, declined levels of blood glucose, TG, TC, AST, ALT, GLU, NEFA, and GSP, and elevate level of HDL-C (P<0.05, P<0.01). Moreover, the two groups showcased reduced lipid droplets and steatosis in the liver, as well as enlarged islets with clear boundaries and alleviated lymphocyte infiltration and karyopyknosis. Western blot results showed that the high-dose herb pair group demonstrated down-regulated protein levels of ACC and SREBP-1 and up-regulated protein level of PPARγ (P<0.01). ConclusionThe HMG can effectively improve the glucose and lipid metabolism in db/db mice by regulating the expression of PPARγ, SREBP-1, and ACC.

ObjectiveTo multidimensionally analyze the clinical effects of Qianyang Yuyin granules on elderly hypertensive patients through an "energy-inflammation-aging" network. MethodsRelevant datasets were retrieved from the GEO database. Gene set enrichment analysis (GSEA) was performed on the gene expression profiles of peripheral blood cells from patients with essential hypertension in dataset GSE24752. The GSEA referenced "GO gene sets" and "KEGG gene sets" to identify significantly enriched gene sets. A clinical trial was conducted using a randomized controlled study design. A total of 40 patients meeting the inclusion criteria were enrolled. The control group received standard antihypertensive treatment with angiotensin receptor blockers (ARBs) or combined calcium channel blockers (CCBs). In contrast,the treatment group received Qianyang Yuyin Granules in addition to the standard treatment for 12 weeks. Blood pressure levels and clinical efficacy were observed,and changes in energy metabolism indicators,DNA damage markers,and senescence-associated secretory phenotype (SASP) in blood were measured using ELISA before and after treatment. ResultsGSEA results indicated significant energy metabolism dysregulation in hypertensive patients. Clinical findings showed that both groups achieved blood pressure control without significant intergroup differences. In terms of clinical efficacy,the treatment group had a significantly higher effective rate compared to the control group (95% vs 65%,P0.05). After treatment,the treatment group showed a significant increase in NAD+ levels (P0.01),with higher levels compared to the control group (P0.05). The treatment group also exhibited a greater reduction in DNA damage marker 8-OHdG (P0.01) and cell adhesion factors ICAM-1 and VCAM-1 (P0.01) compared to the control group. Pro-inflammatory cytokines IL-1β and IL-6 were significantly reduced in the treatment group (P0.01),with greater reductions compared to the control group (P0.05,P0.01). Anti-inflammatory cytokines IFN-α,IL-4,and IL-10 were significantly elevated in the treatment group (P0.01),with higher levels compared to the control group (P0.01). No significant adverse reactions were reported in either group. ConclusionThe "energy- inflammation- aging" network plays an important role in the pathological mechanism of hypertension patients. Qianyang Yuyin granules may delay the aging process by increasing patients' energy metabolism levels,reducing DNA oxidative damage,and maintaining the balance of inflammatory factors.
