OBJECTIVE: Peritoneal dialysis(PD)-associated peritonitis is a common and major complication of PD and the most common cause of technical failure of PD. The presence of bacterial biofilm may be an important factor leading to refractory or recurrence of peritonitis. To investigate the formation and characteristics of bacterial biofilms on PD catheters after peritonitis-associated catheter removal. METHODS: The patients with maintenance PD who were regularly followed up in the Peking University People' s Hospital from June 2007 to January 2022 were retrospectively analyzed. The patients who withdrew from PD because of peritonitis and removed the PD catheter in our hospital and underwent the scanning electron microscope examination of the catheter were selected. The general information of the patients, the electron microscope results of the PD catheter and the bacterial culture results of the PD fluid were summarized. RESULTS: (1) A total of 18 patients were included, 11 were female (accounting for 61.1%). The average age of the patients was (59.1±11.5) years, and the average duration of dialysis was (80.1±47.4) months. Primary kidney diseases were predominantly chronic glomerulonephritis (55.6%), followed by diabetic nephropathy (27.8%), and others (16.6%). The reasons for catheters removal in 18 patients were refractory peritonitis in 11 cases, recurrent peritonitis in 5 cases, and fungal peritonitis in 2 cases. (2) 16 of the 18 patients (88.9%) had catheter bacterial biofilm, and the bacterial biofilm forms were all cocci. Some were arranged in grape-like shapes, and their diameters ranged from about 500 nm to 1 000 nm. The bacterial culture results of peritoneal dialysis fluid showed that the three most common pathogens were Escherichia coli, methicillin-sensitive Staphylococcus aureus (MSSA), and Staphylococcus epidermidis. (3) Among the 18 patients enrolled, 13 patients (72.2%) had peritonitis in the past. The causative bacteria of peritonitis in 9 patients were cocci, including coagulase-negative Staphylococci (Staphylococcus suis, Staphylococcus surface, Staphylococcus xylosus, Staphylococcus warneri), Staphylococcus aureus, Streptococcus (Streptococcus salivarius and Aerococus viridans). CONCLUSION Bacterial biofilm formation on the inner surface of PD catheter is common in peritonitis-associated catheter removal patients. Not all PD catheters removed due to peritonitis have bacterial biofilms. Bacterial biofilms and peritonitis pathogens may not be consistent.

Osteosarcoma (OS), chondrosarcoma (CS), and Ewing sarcoma (ES) represent primary malignant bone tumors and pose significant challenges in oncology research and clinical management. Conventional research methods, such as two-dimensional (2D) cultured tumor cells and animal models, have limitations in recapitulating the complex tumor microenvironment (TME) and often fail to translate into effective clinical treatments. The advancement of three-dimensional (3D) culture technology has revolutionized the field by enabling the development of in vitro constructed bone tumor models that closely mimic the in vivo TME. These models provide powerful tools for investigating tumor biology, assessing therapeutic responses, and advancing personalized medicine. This comprehensive review summarizes the recent advancements in research on 3D tumor models constructed in vitro for OS, CS, and ES. We discuss the various techniques employed in model construction, their applications, and the challenges and future directions in this field. The integration of advanced technologies and the incorporation of additional cell types hold promise for the development of more sophisticated and physiologically relevant models. As research in this field continues to evolve, we anticipate that these models will play an increasingly crucial role in unraveling the complexities of malignant bone tumors and accelerating the development of novel therapeutic strategies.

Objective:To explore the effects of Jianpi Mixture on the glucose receptor/glucagon like peptide-1 (GLP-1)/5-hydroxytryptamine (5-HT) signaling pathway and the mechanism of Jianpi Mixture in improving visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome (IBS-D) rats.Methods:Totally 40 healthy male SPF rats were divided into blank group, model group, Jianpi Mixture low- and high-dosage groups according to the random number table method, with 10 rats in each group. Except for the blank group, the rest of the rats were prepared by the "senna gavage combined with restraint stress" method to replicate the IBS-D spleen deficiency model. The aqueous extract of Jianpi Mixture was 2.52 and 7.56 g/kg in the low- and high-dosage groups, and the same volume of normal saline was given to the blank group and the model group, once a day, for 14 days. On the 1st, 7th and 14th days of administration, the body weight of rats was recorded, the fecal traits of the rats were scored with Bristol score, the visceral sensitivity of IBS-D rats was evaluated by the abdominal wall retraction reflex score (AWR) under rectal dilation, the morphology of colonic mucosal tissues was observed by HE staining, and the protein expressions of T1R2, SLGT1, GLUT2, GLP-1 and 5-HT in colon tissues were detected by immunohistochemical staining.Results:On the 1st, 7th and 14th days of administration, compared with the model group, the weight of the rats in the Jianpi Mixture high-dosage group increased ( P<0.05); on the 14th day of administration, the fecal Bristol score decreased significantly ( P<0.05) and the AWR score increased ( P<0.05); HE staining showed that the mucosal epithelium of colon tissue in the model group was slightly damaged, and local edema was visible. The pathological condition of colonic mucosa in the Jianpi Mixture low- and high-dosage groups was effectively improved; compared with the model group, the expressions of T1R2 and GLP-1 in the Jianpi Mixture low- and high-dosage groups increased ( P<0.05), and the expression of 5-HT decreased ( P<0.05); the protein expressions of GLUT2 and SGLT1 in the Jianpi Mixture high-dosage group increased ( P<0.05). Conclusion:Jianpi Mixture can treat spleen-deficiency IBS-D by restoring the normal expression of intestinal glucose receptors, regulating the secretion of GLP-1/5-HT, improving intestinal motility and alleviating visceral hypersensitivity.

Objective To explore the relationship between serum Interleukin-27(IL-27),Cystatin C(CysC),and Glyceraldehyde-3-phosphate dehydrogenase(GAPDH)antibodies and the severity of disease in children with Neuromyelitis optica spectrum disorder(NMOSD),as well as their impact on prognosis.Methods A total of 102 children with NMOSD admitted to Kunming Children's Hospital from July 2019 to July 2023 were selected,along with 102 healthy during the same period.Serum levels of IL-27,CysC,and GAPDH antibodies were compared between children with NMOSD and healthy children.The levels of serum IL-27,CysC,and GAPDH antibodies were compared among children with varying disease severity.The correlations between serum IL-27,CysC,GAPDH antibodies and disease condition,cerebrospinal fluid markers were analyzed.And 102 children with NMOSD received individualized treatment and were followed up for 1 year.The prognosis was evaluated based on disease relapse,and patients were divided into recurrence group and non-recurrence group.The clinical data,serum IL-27,CysC,and GAPDH antibody levels were compared between the two groups.the impact of serum IL-27,CysC,and GAPDH antibodies on disease recurrence was analyzed,and the predictive value of serum IL-27,CysC,and GAPDH antibodies for disease recurrence was evaluated.Results Children with NMOSD had lower levels of serum IL-27 and CysC and higher levels of GAPDH antibodies than healthy children(P<0.05).Serum IL-27 and CysC levels were negatively correlated with Aquaporin 4(AQP4)-IgG antibody positivity,the number of spinal cord-involved segments,Expanded disability status scale(EDSS)scores,cerebrospinal fluid protein content,and white blood cell count.In contrast GAPDH antibodies were positively correlated with these parameters(P<0.05).After 1-year follow-up,2 cases were lost to follow-up,21 cases relapsed,and 79 cases did not,which were included in the relapse group and non-relapse group,respectively.There were significant differences in the number of spinal cord-involved segments,EDSS scores,and cerebrospinal fluid protein content between the relapse group and non-relapse group(P<0.05).The levels of serum IL-27 and CysC were lower and the levels of GAPDH antibodies were higher in the relapse group than the non-relapse group(P<0.05).Serum IL-27,CysC,and GAPDH antibodies were significantly associated with disease relapse(P<0.05).The Area under the curve(AUC)values for predicting disease recurrence in children with NMOSD based on serum IL-27,CysC,and GAPDH antibodies were 0.748,0.791,and 0.747,respectively,with optimal cutoff values of 38.77 pg/mL,0.79 mg/L,and 55.81 pg/mL,respectively.The combined prediction of disease relapse using these three markers had an AUC of 0.900,which was superior to individual prediction values(Z=2.215,2.137,2.220,P=0.024,0.033,0.023).Conclusion The levels of serum IL-27,CysC,and GAPDH antibodies are significantly correlated with the disease severity and prognosis in children with NMOSD,and can effectively predict the risk of disease recurrence.Combined detection provides more reliable predictive value.

Objective To investigate the application value of the global myocardial work parameters in the non-invasive pressure-strain loop (PSL) technology for early assessment of left ventricular systolic function in patients with chronic kidney disease (CKD). Methods A retrospective analysis was performed on 74 patients with normal left ventricular ejection fraction (LVEF) who were hospitalized in the Nephrology Department of Zhongshan Hospital (Xiamen Branch), Fudan University, from August 2021 to December 2021. Based on CKD stages, patients were divided into early group (CKD stages 1-3) and advanced group (CKD stages 4-5). Additionally, 30 healthy volunteers matched for age and gender were selected as the control group. General clinical data, routine left ventricular ultrasound indicators, myocardial strain, and global myocardial work parameters were collected and compared among the three groups. Correlation analysis and multiple linear regression were used to assess the influencing factors of myocardial work. Results There were no statistically significant differences in global work index (GWI) and global constructive work (GCW) among the three groups. Compared to the control group, both CKD groups showed significantly reduced global work efficiency (GWE), along with significantly increased global waste work (GWW, P＜0.05). The absolute value of global longitudinal strain (GLS) in the advanced CKD group (n＝42) was significantly lower than that in the early CKD group (n＝32; [﹣17.09±0.82]% vs [﹣18.33±0.90]%, P＜0.05), and GWE was also significantly lower (93.00%[90.00%, 95.00%] vs 96.00%[92.25%, 96.75%], P＜0.05), while GWW was significantly higher than that in the early CKD group (150.00 mmHg%[105.25 mmHg%, 215.00 mmHg%] vs 88.00 mmHg%[64.25 mmHg%, 144.50 mmHg%], P＜0.05). Correlation analysis showed that GWE was negatively correlated with the absolute value of GLS and peak strain dispersion (PSD; r＝﹣0.396, ﹣0.558, P＜0.05), GWW was positively correlated with absolute value of GLS, and PSD (r＝0.341, 0.610, P＜0.01). Multiple linear regression results indicated that PSD was an independent influencing factor for GWE (β＝﹣0.558, P＜0.001) and GWW (β＝0.538, P＜0.001). Conclusions The myocardial work parameters GWE and GWW in non-invasive left ventricular PSL technology can identify subclinical left ventricular systolic dysfunction in patients with CKD early and quantitatively.

The intestinal flora and gut barrier function are of great significance for gut function and human health. When the intestinal flora is disrupted and the gut barrier structure is disrupted, it can lead to bacterial translocation, endotoxin influx into the bloodstream, and the production of pro-inflammatory factors, leading to various tissue damage in the body. Tongfu method in TCM can affect the intestinal environment by regulating intestinal permeability and immune response, restoring normal intestinal movement, and regulating the structure and metabolites of intestinal flora, thereby maintaining intestinal homeostasis and body health. The research on regulating intestinal flora and improving intestinal barrier function by Tongfu method can provide reference for further research on the relationship between TCM and intestinal microecology, and provide ideas for clinical treatment.

Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.

Recent studies on male infertility reveal a growing worry: more infertile men are dealing with inflammation in the testis. Analyzing testicular biopsies from infertile men highlights a significant presence of inflammation. This connection, supported by clinical and pathological evidence, emphasizes that testicular inflammation hampers sperm production, leading to lasting declines in sperm count and quality. However, the exact reasons behind male infertility due to orchitis, a type of testicular inflammation, are still uncertain. Understanding these fundamental aspects of molecular signals and cellular mechanisms in testicular inflammation is crucial. Our review delves into recent literature with a dual objective: elucidating potential mechanisms involving immune cells, non-immune cells, and cytokines that link orchitis to male infertility, while also paving the way for precise interventions and solutions to address the challenges of male infertility.
