ObjectiveTo investigate the protective effect of ellagic acid （EA） against bleomycin （BLM）-induced pulmonary fibrosis and associated pulmonary function impairment in mice， and to elucidate its relationship with the regulation of the interleukin（IL）-17/ nuclear factor （NF）-κB/ matrix metalloproteinase （MMP）9 signaling axis. MethodsA pulmonary fibrosis model was established in male C57BL/6J mice via intratracheal BLM injection. Interventions included IL-17 neutralizing antibody， Ixekizumab， SB-3CT， PDTC， or EA were used to modulate the IL-17/NF-κB/MMP9 signaling axis. Pathological changes in lung tissue were observed via HE， Masson， and Sirius red staining. Pulmonary function was assessed using a pulmonary function test （PFT）. Western blot and qRT-PCR were employed to detect related protein and gene expression. Network pharmacology was utilized to predict the potential targets of EA. A protein-protein interaction （PPI） network was constructed using the STRING database and Cytoscape. Molecular docking was performed to validate the binding capability of EA to core targets. ResultsBLM successfully induced obvious pulmonary fibrosis and lung dysfunction in mice， significantly elevating the level of the pro-inflammatory cytokine IL-17. This was associated with the activation of the transcription factor NF-κB p65， leading to the upregulation of the pro-fibrotic factor MMP9. Inhibition of the IL-17/NF-κB/MMP9 signaling axis markedly alleviated the degree of pulmonary fibrosis. EA intervention significantly suppressed the BLM-induced increase in IL-17， blocked the activation of the NF-κB/MMP9 pathway， and consequently reduced lung fibrotic lesions and improved pulmonary function. ConclusionEA may effectively ameliorate BLM-induced pulmonary fibrosis and lung dysfunction in mice， likely by inhibiting the inflammatory and fibrotic responses mediated through the IL-17/NF-κB/MMP9 signaling pathway.

This article reports a rare case of thrombotic microangiopathy (TMA) with renal involvement complicated by allogeneic hematopoietic stem cell transplantation (allo-HSCT). The patient appeared increased serum creatinine 20 d after allo-HSCT, and gradually appeared hypertension, oliguria and edema. Despite discontinuing suspected medications, serum creatinine level did not decrease. Treatment with basiliximab and mycophenolate mofetil was initiated to prevent rejection, leading to gradual normalization of urine output and serum creatinine level. However, after stopping mycophenolate mofetil, the patient experienced recurrent increased blood pressure and decreased pulse oximetry, responding well to prednisone but recurring upon cessation, with gradually increased serum creatinine level. Renal pathology indicated that chronic TMA after allo-HSCT caused renal injury, primarily affecting the glomeruli. The renal function achieved long-term stability through low-dose prednisone and symptomatic treatment. By reviewing relevant literature, we discussed the clinical manifestations, laboratory tests, pathological features and treatment strategies of TMA with renal involvement complicated by allo-HSCT.

This article reviews the diagnosis, therapeutic approaches, and subsequent care for a patient with a complex, long-standing history of encapsulating peritoneal sclerosis (EPS). A 40-year-old male, who had been on peritoneal dialysis (PD) for 11 years, encountered refractory peritonitis, leading to the removal of PD catheter and the subsequent diagnosis of EPS. The patient was transitioned to hemodialysis (HD) and prescribed tamoxifen to mitigate peritoneal fibrosis. After 4 months on HD, the patient underwent a kidney transplant, but acute rejection episode caused the transplanted kidney to fail 3 months postoperatively, necessitating a return to HD. Over the past 7 years, the patient has been repeatedly hospitalized due to recurrent bowel obstructions and infected abdominal fluid accumulation. A multidisciplinary approach, including anti-infective therapy, gastrointestinal intervention, nutritional support, and psychological care, has been instrumental in managing symptoms, and sustaining life. This case underscores the importance of recognizing EPS in long-term PD patients with peritonitis. While discontinuing PD, switching to HD, or receiving kidney transplantation do not halt the progression of EPS, optimized comprehensive management can extend the patient's survival.

Pheochromocytoma is a neuroendocrine tumor that produces catecholamines, leading to elevated blood pressure and metabolic changes in patients. It can result in serious complications affecting the heart, brain, kidneys, and blood vessels, potentially becoming a primary cause of death. Most pheochromocytoma patients present with atypical symptoms, making misdiagnosis or missed diagnosis common. This article reports a case of pheochromocytoma crisis misdiagnosed as severe viral myocarditis and includes a review of the relevant literature.

ObjectiveTo construct a group-based trajectory model (GBTM) for early medication adherence check-in, and to analyze the relationship between different trajectories and treatment outcomes in tuberculosis patients using data that were generated from smart tools for monitoring their medication adherence and check-in. MethodsFrom October 1, 2022 to September 30, 2023, a total of 163 pulmonary tuberculosis patients diagnosed in Fengxian District were selected as the study subjects. The GBTM was utilized to analyze the weekly active check-in trajectories of the subjects during the first 4 weeks and establish different trajectory groups. The χ² tests were employed to compare the differences between groups and logistic regression analysis was conducted to explore the relationship between different trajectory groups and treatment outcomes. ResultsA total of four groups were generated by GBTM analyses, of which a low level of punch card was maintained in group A, 6% of the drug users increased rapidly from a low level in group B, 17% of drug users increased gradually from a low level in group C, and 18% of drug users maintained a high level of punch card in group D. The trajectory group was divided into two groups according to homogeneity, namely the low level medication punch card group (group A) and the high level medication punch card group (group B, group C, and group D). The results of multivariate logistic regression analyses revealed that low-level medication check-in (OR=3.250, 95%CI: 1.089‒9.696), increasing age (OR=1.030, 95%CI: 1.004‒1.056), and not undergoing sputum examination at the end of the fifth month (OR=2.746, 95%CI: 1.090‒7.009) were significantly associated with poor treatment outcomes. ConclusionThe medication check-in trajectory of pulmonary tuberculosis patients within the first 4 weeks is correlated with adverse outcomes, or namely consistent low-level medication adherence check-ins are associated with poor treatment outcomes, while high-level medication adherence check-ins are associated with a lower incidence of adverse outcomes.

Objective To explore the effect of community pharmacy outpatient service on patients with type 2 diabetes mellitus. Methods A non-randomized controlled study was conducted, and type 2 diabetes patients managed in the community were divided into an intervention group of 112 cases and a control group of 110 cases. The control group received routine medication guidance during general practice outpatient visits, while the intervention group received comprehensive pharmacy outpatient service intervention based on routine medication guidance in general practice. Follow-up visits were conducted every 3 months. Repeated measurement analysis of variance and multivariate linear regression analysis were used to evaluate the intervention effect of the pharmacy outpatient service. Results Fasting blood glucose and glycosylated hemoglobin levels in the intervention group showed a decreasing trend with the increase of intervention time compared to pre-intervention time （P<0.01）, with increased duration of weekly exercise, decreased staple food intake, increased vegetable intake, and increased medication adherence score （P<0.01）. After adjusting for confounding factors through multivariate linear regression model, pharmacy outpatient intervention was found to be an independent protective factor for fasting blood glucose level （β=−0.891, P<0.01） and glycosylated hemoglobin level （β=−0.760, P<0.01） in the study subjects. Conclusion The community pharmacy outpatient service could enhance the self-management ability of patients with type 2 diabetes mellitus, and effectively improve patients’ fasting blood glucose and glycosylated hemoglobin.

ObjectiveWe conducted a drug resistance and homology analysis of diarrheagenic Escherichia coli （DEC） in Fengxian District of Shanghai in order to provide a basis for clinical rational drug use， risk monitoring and early warning. MethodsDEC were isolated from diarrheal patients in Fengxian District， Shanghai from 2019 to 2022. The minimum inhibitory concentrations （MIC） of 21 drugs to the DEC were determined. Genotyping and homology analysis were conducted with pulsed-field gel electrophoresis （PFGE）. ResultsThe DEC detection rate of diarrhea cases was 18.99% （131/690）， including enteroaggregative E.coli （EAEC） 64.89% （85/131）， enterotoxigenic E.coli （ETEC） 22.14% （29/131）， enteropathogenic E.coli （EPEC） 12.21% （16/131）， and enterohemorrhagic E.coli （EHEC） 0.76%（1/131）. The DEC detection showed obvious seasonal characteristics with a high incidence in summer. The DEC multidrug resistance rate was 66.41% with a total of 65 drug resistance profiles. The five antimicrobial drugs with the highest resistance rate were ampicillin （60.31%）， nalidixic acid （51.91%）， cefazolin （50.38%）， tetracycline （44.27%）， and cotrimoxazole （35.11%）. The rate of DEC resistance to levofloxacin was significantly increased from 2019 to 2022. Cluster analysis showed that the similarity of 85 EAEC cluster was 58.4%‒100.0%， and 69 band patterns were obtained. The similarity of 29 ETEC cluster was 58.5%‒100.0%， and 13 band patterns were obtained， including 2 dominant band types. The similarity of 16 EAEC clusters was 53.9%‒100.0%， and 15 band patterns were obtained. Five groups of homologous strains were found， consistent with the resistance phenotypes. ConclusionAmong the diarrhea cases， the DEC epidemic intensity is high， the drug resistance situation is severe， and the risk of outbreak infection is high in Fengxian District， Shanghai. Therefore， health monitoring and prevention need to be strengthened.
