ObjectiveTo investigate the facilitators and barriers of home-based exercise rehabilitation for patients with chronic kidney disease (CKD). MethodsFrom December, 2023 to March, 2024, 15 CKD patients receiving treatment at the Nephrology Department of Beijing Bo'ai Hospital and undergoing home-based rehabilitation were selected, as well as eight healthcare professionals from the same department. Semi-structured interviews were conducted, and the data were coded and analyzed using Nvivo 12.0. ResultsTwo main themes were identified. The facilitators included perceived benefits, good health literacy, potential benefits of online media, supervision by healthcare professionals and adequate social support. The barriers included severe negative emotions, adverse effects of complications, insufficient emphasis on exercise rehabilitation, lack of motivation for exercise, constraints related to time and location for exercise, and insufficient rehabilitation support. ConclusionThere are vavious and individual factors influencing home-based exercise rehabilitation for CKD patients, which need an individualized exercise rehabilitation guidance to improve the adherence to self-management.

[Objective] To explore the strategy of blood management in patients with massive transfusion in the frigid plateau region. [Methods] The treatment process of a patient with liver rupture in the frigid plateau region was analyzed, and the blood management strategy of the frigid plateau region was discussed in combination with the difficulties of blood transfusion and literature review. [Results] The preoperative complete blood count (CBC) test results of the patient were as follows: RBC 3.14×10¹²/L, Hb 10⁶ g/L, HCT 30.40%, PLT 115.00×10⁹/L; coagulation function: PT 18.9 s, FiB 1.31 g/L, DD > 6 μg/mL, FDP 25.86 μg/mL; ultrasound examination and imaging manifestations suggested liver contusion and laceration / intraparenchymal hematoma, splenic contusion and laceration, and massive blood accumulation in the abdominal cavity; it was estimated that the patient's blood loss was ≥ 2 000 mL, and massive blood transfusion was required during the operation; red blood cell components were timely transfused during the operation, and the blood component transfusion was guided according to the patient's CBC and coagulation function test results, providing strong support and guarantee for the successful treatment of the patient. The patient recovered well after the operation, and the CBC test results were as follows: RBC 4.32×10¹²/L, Hb 144 g/L, HCT 39.50%, PLT 329.00×10⁹/L; coagulation function: APTT 29.3 s, PT 12.1 s, FiB 2.728 g/L, DD>6 μg/mL, FDP 25.86 μg/mL. The patient was discharged after 20 days, and regular follow-up reexamination showed no abnormal results. [Conclusion] Individualized blood management strategy should comprehensively consider the patient’s clinical symptoms, the degree of hemoglobin decline, dynamic coagulation test results and existing treatment conditions. Efficient and reasonable patient blood management strategies can effectively improve the clinical outcomes of massive transfusion patients in the frigid plateau region.

OBJECTIVE To investigate the ameliorating effect and mechanism of the effective substance groups from Artemisia ordosica（Abbreviated as HSH） on rheumatoid arthritis （RA） based on cluster of differentiation 4/lymphocyte cell-specific protein- tyrosine kinase/zeta-chain-associated protein kinase of 70 kDa/interleukin-17（CD4/LCK/ZAP70/IL-17） signaling pathway. METHODS The rats were divided into normal group， model group， HSH low-dose， medium-dose and high-dose groups （2.7， 10.8， 21.6 mg/kg） and positive control group （Tripterygium glycosides tablet， 6.3 mg/kg）， with 10 rats in each group. Except for normal group， RA rat model was induced by complete Freund’s adjuvant in other groups. After modeling， each group was given relevant medicine or normal saline intragastrically， once a day， for 28 consecutive days. The changes in ankle joint swelling and arthritis index in rats were determined； the pathological changes of ankle joint tissue were observed； the levels of inflammatory factors [IL-1β， IL-21， IL-17A， IL-2， interferon-γ （IFN-γ） and IL-6] in serum and joint fluid of rats were determined； the levels of Th1， Th17 and Treg cells in the whole blood and spleen of rats were detected； protein and mRNA expressions of LCK， proto-oncogene tyrosine-protein kinase Fyn （Fyn）， ZAP70， CD45， RAR-related orphan receptor γt （RORγt）， and forkhead box protein 3 （Foxp3） in ankle synovial tissue were determined. RESULTS Compared with normal group， the changes in ankle joint swelling， arthritis index， the levels of IL-1β， IL-21， IL-17A， IL-2， IFN-γ and IL-6 in serum and joint fluid， the levels of Th1， Th17 cells and Th17/Treg value in whole blood and spleen， and the protein and mRNA expression levels of LCK， Fyn， ZAP70， CD45， and RORγt in ankle joint synovium were all significantly increased/elevated （P＜0.05）. The level of Treg cells in the spleen， as well as the protein and mRNA expression levels of Foxp3 in the ankle joint synovium were significantly decreased （P＜0.05）. Compared with model group， most of the above-mentioned indicators were significantly reversed in the positive control group and all dose groups of HSH （P＜0.05）. The degree of pathological changes in ankle joint tissues was markedly improved， and inflammation was alleviated. CONCLUSIONS HSH can regulate the cascade reactions in the CD4/LCK/ZAP70/IL-17 pathway within the T-cell receptor signaling pathway， thereby modulating the Th17/Treg balance. This leads to the suppression of inflammatory responses and the alleviation of synovial tissue damage in rats with RA.

Objective To analyze the types and distribution of microbiome in intestinal and lung tissues of children with asthma, and to explore the correlation between microbiota changes and asthma. Methods From 2021 to 2023, a total of 28,939 children with asthma who visited Ezhou Central Hospital, Maternal and Child Health Hospital or Ezhou Egang Hospital were selected as the study subjects, and 2,000 healthy children who underwent outpatient physical examinations at these three hospitals during the same period were selected as the control group. The distribution and characteristics of intestinal and pulmonary microbiome in the two groups were analyzed by 16SrDNA sequencing. Logistic regression analysis model was used to analyze the correlation between microbiota distribution and asthma occurrence. Results In the intestinal tissues of children with asthma compared to healthy children, the abundance of Bacteroidetes at the phylum level decreased, while the abundance of Firmicutes and Proteobacteria increased significantly (P<0.05), and the abundance of Prevotalle and Clostridium at the genus level increased significantly. In lung tissues of asthmatic children compared to health children, the abundance of Firmicutes at the phylum level decreased while the abundance of Proteobacteria increased significantly (P<0.05), and the abundance of Neisseria, Prevotella and Actinomyces at the genus level increased significantly. Binary logistic regression results showed that the abundances of Lactobacillus (OR=0.842, 95% CI: 0.533-0.947), Bacteroides fragilis (OR=0.649, 95%CI: 0.377-0.890), Bifidobacterium (OR=0.901, 95% CI: 0.633-0.994), and Parabacteroides distasonis (OR=0.547, 95% CI: 0.192-0.708) in the intestinal tissues were all protective factors for the asthma in children. In the lung tissue, the abundance of Neisseria (OR=2.140, 95% CI: 1.749-3.305) was a risk factor for the asthma in children, and Prevotella (OR=0.691, 95% CI: 0.491-0.926) was a protective factor for the asthma in children (P<0.05). Conclusion The dysbiosis of intestinal and pulmonary microbiome is closely related to the occurrence of asthma in children, and the detection of microbiota is of great significance for the diagnosis of childhood asthma.

Objective: To perform serological identification and molecular analysis of four samples with antibodies against high-frequency antigens, and to track the condition of newborns after delivery. Methods: Blood group serological tests were conducted using tube method, and unexpected antibody screening and identification were performed using polybrene and human globulin card. Gene haplotype analysis of blood group system was performed using PacBio third-generation sequencing. The DNA mutations were confirmed through Sanger sequencing. Results: Four samples showed normal blood types in common blood type systems. However, they were positive in all unexpected antibody screening and identification, with negative direct antiglobulin tests results. Third-generation sequencing revealed 3 cases of c.376C>T homozygous mutation and 1 case of c.421C>A homozygous mutation in the ABCG2 gene. Three pregnant women gave birth to four children, all of whom developed hyperbilirubinemia, accompanied by decreased red blood cell count and normal or low hemoglobin concentration. Conclusion: Four samples were obtained from individuals with the rare Jr(a-) blood group. Immunization during pregnancy led to the production of anti-Jr antibody, which may contribute to hyperbilirubinemia in newborns.

BACKGROUND: Endoscopic sphincterotomy (EST) is widely used to treat common bile duct stones (CBDS); however, long-term studies have revealed the increasing incidence of recurrent CBDS after EST. Loss of sphincter of Oddi function after EST was the main cause of recurrent CBDS. Reparation of the sphincter of Oddi is therefore crucial. This study aims to investigate the effectiveness and safety of endoclip papilloplasty (ECPP) for repairing the sphincter of Oddi and elucidate its mechanism. METHODS: Eight healthy Bama minipigs were randomly divided into the EST group and the ECPP group at a 1:1 ratio, and bile samples were collected before endoscopy and 6 months later. All minipigs underwent transabdominal biliary ultrasonography for the diagnosis of cholelithiasis 6 months after endoscopy. The biliary microbiota composition and alpha and beta diversity were analyzed by 16S ribosomal RNA gene sequencing. Differential metabolites were analyzed by bile acid metabolomics to explore the predictive indicators of cholelithiasis. RESULTS: Three minipigs were diagnosed with cholelithiasis in the EST group, while none in the ECPP group showed cholelithiasis. The biliary Firmicutes/Bacteroidota (F/B) ratio was increased after EST and decreased after ECPP. The Chao1 and observed species index significantly decreased 6 months after EST ( P  = 0.017 and 0.018, respectively); however, the biliary α-diversity was similar before and 6 months after ECPP. The β-diversity significantly differed in the EST group before and 6 months after EST, as well as in the ECPP group before and 6 months after ECPP (analysis of similarities [ANOSIM]: R  = 0.917, P  = 0.040; R  = 0.740, P  = 0.035; respectively). Glycolithocholic acid (GLCA) and taurolithocholic acid (TLCA) accumulated in bile 6 months after EST. CONCLUSIONS ECPP has less impact on the biliary microenvironment than EST and prevents duodenobiliary reflux by repairing the sphincter of Oddi. The bile levels of GLCA and TLCA may be used to predict the risk of cholelithiasis.

Objective To investigate the effect of gentiopicroside on osteogenic differentiation of human bone marrow mesenchymal stem cells (BMSCs), and to determine whether its mechanism involves the stromal cell-derived factor 1(SDF-1)/C-X-C chemokine receptor 4 (CXCR4) pathway. Methods BMSCs were divided into six groups: normal culture control group, osteogenic induction model group, low-dose gentiopicroside (L-gentiopicroside, 10 μmol/L) group, medium-dose gentiopicroside (M-gentiopicroside, 20 μmol/L) group, high-dose gentiopicroside (H-gentiopicroside, 40 μmol/L) group, and H-gentiopicroside+SDF-1/CXCR4 pathway inhibitor (AMD3100) group (H-gentiopicroside+AMD3100, 40 μmol/L gentiopicroside+10 μg/mL AMD3100). Cell viability, apoptosis, ALP activity, mineralized nodule formation, and protein levels of the SDF-1/CXCR4 pathway were assessed using the CCK-8 assay, flow cytometry, ALP staining, Alizarin Red S staining, and Western blotting, respectively. Results No mineralized nodules were observed in either the control and model group, although the color of the model group deepened. Compared with the control group, the model group showed significantly increased A value, ALP activity, expression levels of Runt related transcription factor 2 (RUNX2), osteopontin (OPN), SDF-1, CXCR4 proteins, along with a lower apoptosis rate. Compared with the model group, the L-gentiopicroside, M-gentiopicroside and H-gentiopicroside groups showed dose-dependently (L Humans ; Receptors, CXCR4/genetics* ; Mesenchymal Stem Cells/metabolism* ; Chemokine CXCL12/genetics* ; Iridoid Glucosides/pharmacology* ; Osteogenesis/drug effects* ; Cell Differentiation/drug effects* ; Signal Transduction/drug effects* ; Cells, Cultured ; Apoptosis/drug effects* ; Bone Marrow Cells/metabolism*

Objective To analyze the main epidemiological characteristics of fungal infection in this hospital in the past 7 years,and to provide reference for clinical treatment and prevention and control strategies of fun-gal infection.Methods The fungal data and clinical data of related patients isolated from clinical samples in Peking Union Medical College Hospital from early January 2018 to the end of May 2024 were selected,and the main epidemiological characteristics of fungal infection in this hospital were identified and described through multi-angle statistical analysis.Results A total of 4 479 patients with filamentous fungal infection were en-rolled.The proportion of male patients[57.5％(2 576/4 479)]was higher than that of female patients[42.5％(1 903/4 143)],mainly distributed in internal medicine,Intensive Care Unit(ICU)and emergency de-partment,among which internal medicine accounted for the highest proportion[50.0％(2 241/4 479)].About 90.0％of the specimens were from the lower respiratory tract,in addition to specimens from skin and soft tis-sue,tissue,ear and blood culture.In terms of seasonal distribution,there are more patients in winter.The fun-gi were mainly composed of Aspergillus,Mucor,Cerdosporium,Fusarium and Penicillium,among which As-pergillus was the most abundant,accounting for 74.6％of the total.Aspergillus fumigatus was the most a-bundant Aspergillus,accounting for 42.5％of the total Aspergillus(1 418/3 340).Among the related infec-tions caused by mold,Aspergillus was the most common in the lower respiratory tract,accounting for 76.8％.Among them,Aspergillus fumigatus accounted for the highest proportion(33.6％).98.6％of the molds infected the ear were Aspergillus,of which Aspergillus niger and Aspergillus terreus were the most common.Skin infections are mainly caused by Sporothrix schenckii,Trichophyton rubrum,Microsporum ca-nis.The results of in vitro drug sensitivity test showed that the four common Aspergillus isolated in this hos-pital were sensitive to voriconazole,and amphotericin B had better antifungal activity against Mucorales in vitro.Conclusion Based on the main epidemiological characteristics of fungal infections in this hospital,it is recommended that special attention be paid to the admission of patients in the respiratory department during the peak infection period in autumn and winter.In the treatment of fungal infections in different regions and on different body parts,attention should be paid to the differences in the distribution of bacterial species.

Objective To investigate the early predictive value of combined detection of serum sodium,heparin-binding protein-to-albumin ratio(HBP/ALB)and interleukin-10(IL-10)in Ka-wasaki disease shock syndrome(KDSS)caused by Kawasaki disease in children.Methods A total of 105 children with KDSS caused by Kawasaki disease(KDSS group)and 105 children with Kawasa-ki disease(control group)were selected as study subjects.Clinical data,serum sodium levels,HBP/ALB and IL-10 levels were compared between the two groups.Multivariate logistic regression a-nalysis was used to screen the influencing factors of KDSS caused by Kawasaki disease in children a-mong serum sodium,HBP/ALB and IL-10.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the predictive value of traditional prediction schemes(coronary artery dam-age and IVIG resistance)and new prediction schemes(serum sodium and HBP/ALB,IL-10)for KDSS caused by Kawasaki disease in children.Results The proportion of patients with coronary ar-tery damage and IVIG resistance was significantly higher in the KDSS group than those in the control group(P＜0.05).Serum sodium levels were lower,while HBP/ALB and IL-10 levels were higher in the KDSS group compared to the control group(P＜0.05).Multivariate logistic regression analysis showed that serum sodium,BP/ALB and IL-10 were influencing factors of KDSS caused by Kawasaki diseasein children(P＜0.05).For traditional prediction schemes,the areas under the curves(AUCs)for coronary artery damage,IVIG resistance and their combination in predicting KDSS caused by Kawasaki disease were 0.795,0.676 and 0.873,respectively(P＜0.05);for new prediction schemes,the AUCs for serum sodium,HBP/ALB,IL-10 and their combination in predicting KDSS were 0.767,0.824,0.760 and 0.945,respectively(P＜0.05).The AUC for the combination of serum sodium,HBP/ALB and IL-10 was greater than that for the combination of coronary artery dam-age and IVIG resistance(P＜0.05).Conclusion Decreased serum sodium,elevated HBP/ALB and elevated IL-10 are associated with KDSS caused by Kawasaki disease in children.Combined prediction using serum sodium,HBP/ALB and IL-10 has a high predictive value for KDSS caused by Kawasaki disease in children.
