Objective: To investigate the efficacy, safety, and traditional Chinese medicine (TCM) medication patterns of rituximab (RTX) combined with TCM on treating children with steroid-dependent nephrotic syndrome (SDNS). Methods: One hundred and forty-three children with SDNS who visited the Pediatric Nephrology Department of the First Affiliated Hospital of Henan University of Chinese Medicine from January 2018 to December 2022 were enrolled. A cohort study design was adopted, with " RTX treatment" as the exposure factor. Children who met this exposure factor were assigned to the RTX cohort (RTX, glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment), whereas those who did not were assigned to the basic treatment cohort (glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment ), and followed up for 6 months. The frequency of urinary protein recurrences, urinary protein remission duration, proportion and duration of steroid reduction and cessation, cumulative usage of steroids, proportion of recurrence, recurrence amount of steroid used, efficacy of TCM syndrome, and laboratory and safety indicators after treatment, and height and CD19+ B cell count before and after treatment were compared between the two cohorts. The medication patterns of TCM in the two cohorts were analyzed using frequency statistics, association rule analysis, and systematic clustering analysis. Results: Compared with the basic treatment cohort, the RTX cohort showed a decrease in the frequency of urinary protein recurrence, extended sustained remission of urinary protein, an increase in the proportion of steroid reduction and cessation, a shorter duration of steroid reduction and cessation, a decrease in cumulative steroid dosage, a lower recurrence rate, a decrease in CD19+ B cell count, and a decrease in 24-h urinary total protein quantification and the level of cholesterol (P<0.05). No significant difference in the recurrence amount of steroid used, height, TCM syndrome efficacy, albumin, aspartate transaminase, blood urea nitrogen, platelet count, and safety indicators between the two cohorts. Children with SDNS were mostly characterized by qi and yin deficiency syndrome, followed by spleen and kidney yang deficiency syndrome. A total of 175 TCMs were included, including 28 high-frequency drugs such as Huangqi, Fuling, Gancao, Baizhu, Dangshen, and Jiuyurou. The primary use of medication is to nourish the qi and spleen, nourish the kidney, and warm yang. The analysis of association rules yielded eight binary associations and ten three-phase associations, with Huangqi, Baizhu, Fuling, and Dangshen, being the most closely related. Cluster analysis identified four TCM combinations, primarily focusing on tonifying kidney and replenishing essence, benefiting qi and nourishing yin, and removing blood stasis. Conclusion RTX combined with TCM syndrome differentiation treatment can reduce the recurrence frequency of SDNS, prolong the remission period, reduce the glucocorticoid dosage, and have no marked effect on height growth. No apparent adverse reactions were observed. TCM should focus on nourishing qi and yin while removing blood stasis.

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 investigate the potential mechanism of Liangxue Tuizi Formula （凉血退紫方， LXTZF） in treating Henoch-Schönlein Purpura （HSP） by examining its regulatory effect on neutrophil extracellular trap （NETs） dysregulation via the rapidly accelerated fibrosarcoma kinase （RAF）/mitogen-activated protein kinase （MEK）/extracellular signal-regulated kinase （ERK） signaling pathway. MethodsSeventy Wistar rats were randomly allocated into a blank control group （n=14） and a modeling group （n=56）. Rats in the modelling group underwent an eight-week modelling period to establish HSP rat models with blood-heat syndrome via modified ovalbumin （OVA） induction method combined with oral administration of heat-property Chinese herbal medicine. Fifty successfully modeled rats were subsequently randomly divided into five groups （n=10 per group）， model group， compound glycyrrhizin group， LXTZF group， RAF inhibitor group， and LXTZF + RAF agonist group. Additionally， 10 rats were selected from the original blank control group for the final experiment. From the 11th week of modelling， rats in the blank control group and the model group received 1 ml/（100 g·d） ultrapure water via oral administration， in addition to 0.5 ml/（kg·d） 0.9% sodium chloride solution via intraperitoneal injection. The LXTZF group and the compound glycyrrhizin group received 7.5 g/（kg·d） LXTZF granule suspension via gavage， 13.5 mg/（kg·d） compound glycyrrhizin suspension via gavage， respectively. The RAF inhibitor group received 1 mg/（kg·d） GW5074 suspension via intraperitoneal injection and ultrapure water via oral administration； the LXTZF + RAF agonist group received 7.5 g/（kg·d） LXTZF granule suspension via gavage and 1 mg/（kg·d） paclitaxel suspension via intraperitoneal injection. All administrations were performed once daily for 4 weeks. After intervention， skin tissue histopathology was examined by hematoxylin and eosin （H&E） staining， immunoglobulin A （IgA） deposition was assessed via immunofluorescence， serum levels of neutrophil elastase （NE）， tumor necrosis factor-α （TNF-α）， and vascular cell adhesion molecule-1 （VCAM-1） were measured using enzyme-linked immunosorbent assay （ELISA）， serum myeloperoxidase （MPO） level was determined by a colorimetric assay； the mRNA expression levels of RAF， MEK， and ERK in skin tissue were detected by real-time quantitative polymerase chain reaction （RT-qPCR）； and the protein expression of RAF， MEK， ERK， as well as phosphorylated MEK （p-MEK） and phosphorylated ERK （p-ERK）， were analyzed by Western Blot. ResultsSkin tissue in the blank control group rats remained normal， whereas the model group exhibited neutrophil infiltration and haemorrhage with red blood cell rupture. In all drug intervention groups， neutrophil infiltration and haemorrhagic exudation reduced markedly， with LXTZF group demonstrating the most pronounced improvement. Compared with the blank control group， rats in the model group exhibited enhanced IgA fluorescence intensity in skin tissue， elevated serum levels of NE， MPO， TNF-α and VCAM-1， increased mRNA expression of RAF， MEK， ERK1 and ERK2， as well as heightened RAF protein levels and p-MEK/MEK and p-ERK/ERK ratios （P＜0.05）. Compared with the model group， the drug intervention groups exhibited reduced IgA fluorescence intensity in skin tissue， along with decreased serum levels of NE， MPO， TNF-α， and VCAM-1 （P＜0.05）. In LXTZF group and RAF inhibition groups， reduced mRNA expression of RAF， MEK， ERK1， and ERK2 was observed in rat skin tissue， alongside decreased RAF protein levels and reduced p-MEK/MEK and p-ERK/ERK ratios （P＜0.05）. Compared with LXTZF + RAF agonist group， the compound glycyrrhizin group， LXTZF group， and RAF inhibitior group exhibited reduced IgA fluorescence intensity in skin tissue， decreased serum NE， MPO， TNF-α， and VCAM-1 levels， and decreased MEK mRNA expression and p-MEK/MEK ratio （P＜0.05）. ConclusionThe potential mechanism by which LXTZF treats Henoch-Schönlein purpura with blood heat syndrome may involve blocking the RAF/MEK/ERK signaling pathway in skin tissue， and suppressing excessive formation of NETs， thereby reducing IgA deposition in dermal microvessels and attenuating systemic inflammatory responses.

Objective:To analyze the influencing factors of achieving textbook outcome (TO) after pancreaticoduodenectomy (PD) in patients with pancreatic ductal adenocarcinoma, and to construct a nomograph model to explore its predictive value in TO.Methods:The clinical data of 205 patients with pancreatic ductal adenocarcinoma treated by PD in Henan University People's Hospital from January 2019 to December 2022 were analyzed retrospectively, including 88 males and 117 females with the age of (61.3±9.8) years old. Patients were divided into two groups based on whether they achieved TO after surgery: TO group ( n=113) and non-TO group ( n=92). Clinical data such as age, gender, intraoperative blood loss, operation time, blood transfusion volume, pancreatic CT value, and tumor differentiation degree were collected. Logistic regression analysis screened the influencing factors of PD postoperative TO and built a nomogram model. The performance of the nomogram model was evaluated using receiver operating characteristic (ROC) curve, calibration diagram, and decision curve analysis. Results:Multivariate logistic regression analysis showed that the higher the degree of tumor differentiation was in patients with pancreatic ductal adenocarcinoma (high differentiation to medium differentiation: OR=7.20, 95% CI: 1.20-43.28; high differentiation to low differentiation: OR=16.55, 95% CI: 2.01-136.11), CT value>38.45 Hu ( OR=0.29, 95% CI: 0.13-0.65), blood transfusion volume ≤350 ml ( OR=8.05, 95% CI: 2.94-22.01) and operative time ≤407.5 min ( OR=10.88, 95% CI: 3.90-30.41), the easier it was to achieve TO after PD (all P<0.05). Based on the above influencing factors, a nomogram model of the postoperative effect of PD on TO was established, and the consistency index of this column graph model was 0.863 (95% CI: 0.816-0.911). The sensitivity and specificity of ROC curve were 0.804 and 0.752, respectively. The calibration diagram showed that the calibration curve fits well with the ideal curve, and the decision curve showed that the model had obvious positive net benefit. Conclusion:The degree of tumor differentiation, CT value, blood transfusion volume, and operation time are independent influencing factors for the achievement of TO after PD in patients with pancreatic ductal adenocarcinoma, and the nomogram model constructed based on which has good predictive performance for TO.

Objective:To analyze the effect of sarcopenia on the prognosis of patients with hepatocellular carcinoma (HCC) after laparoscopic radical resection.Methods:Clinical data of 165 patients with HCC undergoing laparoscopic radical resection in Henan University People's Hospital from January 2018 to December 2021 were retrospectively analyzed, including 122 males and 43 females, aged (55.5±11.4) years. Patients were divided into sarcopenia group ( n=79) and control group (non-sarcopenia, n=86) according to the skeletal muscle index. The survivals were analyzed using the Kaplan-Meier method, and were compared by the log-rank test. Univariate and multivariate Cox regression were utilized to analyze the effect of sarcopenia on the prognosis of HCC after laparoscopic radical surgery. Results:The 1- and 3-year cumulative survival rates of control group were 96.4% and 81.2%, which were higher than those of the sarcopenia group (83.2% and 48.9%, respectively, χ2=19.67, P<0.001). The 1- and 3-year recurrence-free survival (RFS) rates of control group were 88.4% and 66.1%, which were higher than those of sarcopenia group (70.9% and 37.7%, respectively, χ2=18.80, P<0.001). Multivariate Cox regression analysis showed that the risk of recurrence ( HR=1.35, 95% CI: 1.20-1.59, P<0.001) and the risk of death ( HR=2.21, 95% CI: 1.23-3.41, P=0.001) after laparoscopic radical resection for HCC in patients with sarcopenia rises compared to non-sarcopenic patients. Conclusion:Sarcopenia is a risk factor for the survival and recurrence of HCC after laparoscopic radical surgery.

The clinical data from 16 patients who underwent surgery for acute type A aortic dissection under ultra-fast-track anesthesia (UFTA) in the Second Affiliated Hospital of Nanjing Medical University from August 2023 to December 2023 were collected, and the experience of anesthesia management was analyzed and summarized. UFTA strategy was to reduce inflammation and perform multi-organ protection in the perioperative period through cardiopulmonary bypass methods, medications, etc. According to the process of operation, the long-term and short-acting anesthetic drugs were accurately used to achieve the patient′s awakening immediately after the operation. Deep anesthesia extubation, remifentanil infusion techniques, and nasal high-flow ventilation were used to enable patients to be removed from the endotracheal tube with low stress under the premise of safety. All the patients successfully completed anesthesia induction and anesthesia maintenance. The average surgery duration was (413±92) min, the average anesthesia duration was (480±100) min, the cardiopulmonary bypass time was (168±42) min, the cardiac arrest time was (119±36) min, and the deep hypothermic circulatory arrest lasted (24±5) min. Of these patients, 14 underwent deep hypothermic circulatory arrest combined with unilateral cerebral perfusion via the right axillary artery, and 2 underwent deep hypothermic circulatory arrest combined with retrograde cerebral perfusion via the superior vena cava. All the patients had their tracheal tubes removed within 30 min postoperatively, with blood gas analysis and hemodynamics being within or close to normal ranges. The average postoperative intensive care unit stay time was 6 (3, 11) days, and the total length of hospital stay was (23±8) days. The total hospitalization time extended 20 days in 7 patients due to postoperative complications. All the patients recovered and were discharged. In conclusion, the application of UFTA strategy is safe and feasible in the patients with acute type A aortic dissection, allowing for immediate extubation in the operating room.

Objective:To investigate the risk factors for postsurgical gastroparesis syndrome (PGS) after laparoscopic complete mesocolic excision (CME) for right colon cancer.Methods:The clinical data of 358 patients who underwent laparoscopic CME for right colon cancer were retrospectively analyzed. Univariate and multivariate logistics regression were used to analyze the independent risk factors for PGS.Results:PGS occurred in 19 patients (4.8%). Logistic regression analysis showed that preoperative anxiety score (PAS-7)≥14 ( OR=6.450, P=0.039), preoperative serum albumin<35 g/L ( OR=9.302, P=0.011), colon cancer at hepatic flexura ( OR=9.782, P=0.007), No.206 group lymph node dissection ( OR=8.317, P=0.004), and intra-abdominal infection ( OR=5.755, P=0.043) were independent risk factors for PGS. Conclusion:Patient's preoperative health status, tumor location, scope of lymph node dissection and postoperative intra-abdominal infection are all risk factors related to PGS after CME for right colon cancer.

A comprehensive understanding of the nutritional composition and active components of human milk are important for promoting infant health. However, in the design and implementation of scientific research on human milk, the lack of standardized research and implementation methods have led to the collection, storage, and testing processes of human milk samples being largely based on reference literature and practical experience. This has resulted in variability in the representativeness of human milk samples and differences in the comparability of research results between different studies. This article summarizes the principles and guidelines for the " Specification for collection and storage of human milk samples for research", published by the Chinese Nutrition Society on December 30, 2022, and discusses the feasibility and importance of standardized management in the process of scientific research on human milk.

Objective: To synthesis a Gd-labeled molecular probe capable of responding to fibroblast activation protein(FAP) highly expressed in tumor-associated fibroblasts for magnetic resonance imaging studies of pancreatic cancer. Methods: The chemical structure of Z-Gly-Pro-Cys-Lys(Gd-DOTA)-CBT(contrast agent 1) was characterized through mass spectrometry analysis.High-performance liquid chromatography(HPLC) was used to verify the contrast agent 1 formed a dimer under the cleavage of fibroblast activation protease(FAP) in vitro,and further self-assembled to form Gd-nanoparticles.The cell counting Kit-8(CCK-8) assay was used for biological safety analysis.BxPc-3 tumor-bearing mice were established and randomly divided into three groups,3 mice intravenously(i.v.) injected with 0.08 mmol/kg contrast agent 1 through tail vein were designated as the experimental group,3mice i.v.injected with 0.08 mmol/kg Gd-DTPA were designated as the control group,and 3 mice i.v.injected with normal saline were designated as the blank control group(n=3).Dynamic MR scanning from 0 to 3 hours was performed for them,respectively.The enhancement effects of T1-and T2-weighted imaging were observed and the rate of change in the tumor-to-muscle ratio(T/M) over time was analyzed. Results: Contrast agent 1 efficiently responded to FAP in vitro,forming dimers under the action of FAP,and further self-assembled to form nanoparticle structures.Contrast agent 1 has good biocompatibility.The BxPc-3 tumor-bearing mice showed that the T1-weighted contrast of the tumor reached its highest level at 2 h post injection of contrast agent 1 or Gd-DTPA.In T1-weighted imaging,the T/M at 2 h in the experimental group was 135.20%±0.06% of 0 h,the T/M at 2 h in the Gd-DTPA group was 115.70%±0.05% of 0 h and the T/M at 2 h in the saline group was 113.5%±0.02% of 0h.Compared with Gd-DTPA control group,the experimental group had significantly enhanced T1-weighted MR contrast,and the difference was statistically significant(P<0.01).In tumor T2-weighted imaging,the T/M quantitative analysis showed that the tumor T2-weighted contrast enhancement of the three groups was relatively small,and the T/M of the experimental group and the control group at 0.5 h was 94.60±0.03% and 106.30±0.04% of the 0 h,respectively.In the normal saline group,T/M at 0.5 h was 102.20±0.002% of that at 0 h,and no significant enhancement of the T2-weighted MR contrast of tumor was observed. Conclusion Successfully construct a FAP-responsive molecular probe which can self-assemble to form a Gd-nanoparticle structure in tumor cells under the cleavage of FAP,effectively improving the enrichment of Gd in the target region,and enhancing T1-weighted magnetic resonance imaging of pancreatic cancer,which has potential clinical application value.
