Abelmoschi Corolla is extensively applied in managing diabetic nephropathy (DN) and other renal conditions due to its diuretic and detoxifying properties. The primary bioactive constituents of Abelmoschi Corolla are flavonoids, including notably rutin, hyperoside, isoquercitrin, hibifolin, myricetin, quercetin 3-O-β-D-glucuronide, and quercetin. These flavonoid components can influence the pathological progression of DN via a multi-target synergistic mechanism, effectively reducing proteinuria levels. This review examines the roles of Abelmoschi Corolla and its flavonoid components in modulating the key pathological aspects of DN and their underlying mechanisms, and briefly discusses the metabolic patterns of its bioactive components and the research progress in combined medication, aiming to provide a forward-looking scientific foundation for further investigating the molecular mechanisms and clinical applications of Abelmoschi Corolla in DN treatment.

Objective:To evaluate the efficacy and safety of upadacitinib in the real-world treatment of difficult-to-treat Crohn's disease (DTT-CD) .Methods:This multicenter, retrospective cohort study included patients diagnosed with DTT-CD according to the International Organization for the Study of Inflammatory Bowel Diseases (IOIBD) criteria, and treated at eight Chinese inflammatory bowel disease centers between January 2023 and March 2025. Clinical outcomes were assessed after 12 weeks of induction therapy with upadacitinib (45 mg qd), including clinical remission rate, clinical response rate, and incidence of adverse events.Results:Among 151 enrolled DTT-CD patients, the clinical remission rate was 47.0%, and the clinical response rate was 90.7% after 12 weeks of treatment. Adverse events occurred in 42 cases (27.8%) .Conclusion:Upadacitinib demonstrated favorable efficacy in inducing clinical remission in DTT-CD patients, with a good safety profile at the induction dose (45 mg qd) .

Objective With the increasing demand from the country for optimizing the allocation of medical resources and improving service balance,this study aims to promote the improvement of regional medical service levels through the explora-tion and practice of the management model of provincial medical quality control centers.Methods The First Affiliated Hospital of Sun Yat-sen University,as the affiliated unit of one of the 14 provincial quality control centers,organizes the quality control center to play a professional role and improve its management efficiency through stable construction,solid framework,reorgani-zation,and multiple support.Results With the leadership and support of the health administrative department in Guangdong Province,the hospital has organized the provincial quality control center to carry out its work in an orderly manner,promoting the continuous improvement of the comprehensive strength of regional medical services and key indicators of various professional qual-ity control centers.Conclusion The management model of the quality control center in this study has shown initial effectiveness.

This article presents the anti-infective treatment and pharmaceutical care of an elderly patient with liver cirrhosis complicated with severe psittacosis.Based on the pathophysiological characteristics of infection in patients with severe liver diseases and in combination with relevant guidelines,the combined regimen of omadacycline+moxifloxacin was adopted to treat psittacosis.In case of recurrent episodes,Aspergillus fumigata was detected in the metagenomic next-generation sequencing of bronchoalveolar lavage fluid.Initially,voriconazole was administered for treatment,and later switched to posaconazole.Additionally,clinical pharmacists provided pharmaceutical care encompassing adverse reaction monitoring and voriconazole therapeutic drug monitoring.The patient's infection was effectively controlled,body temperature returned to normal,white blood cell counts and platelet counts basically returned to normal range,serum high-sensitive C-reactive protein,procalcitonin,and other inflammatory indicators significantly decreased,and the patient was discharged.Clinical pharmacists assisted clinicians in formulating a reasonable anti-psittacosis treatment plan and provided individualized pharmaceutical care to ensure the effectiveness and safety of clinical drug treatment.

Objective To explore the solution of local water-fat separation swap artifacts(WFS-SA)on nasopharyngeal T1WI-itera-tive decomposition of water and fat with echo asymmetry and least-squares estimation(T1WI-IDEAL)enhanced examination images.Methods Thirty-seven patients with obvious WFS-SA on nasopharyngeal enhanced examination using the A group T1WI-IDEAL param-eters were collected.Scans with modified parameters B,C,and D groups were subsequently performed based on the A group parame-ters.Subjective ratings of image quality were conducted on the four image groups,and the image signal-to-noise ratio(SNR)of the posterior wall of the nasopharynx and medulla oblongata was quantified.The total number of artifact slices(TAS),total artifact area(TAA),and maximum single-slice artifact area(SSAAmax)of the WFS-SA in the four image groups were recorded.The consistency of image quality ratings between the two technologists was analyzed via the intraclass correlation coefficient(ICC),and one-way analysis of variance or rank-sum test was used to compare the SNR,TAS,TAA,and SSAAmax among the four image groups.Results The subjective rating for modified B,C,and D groups of T1WI-IDEAL images by two technologists was deemed satisfactory(ICC=0.721-0.928,P<0.001).Significant variations in image quality ratings were observed among the three groups(H=45.131,P<0.001),with ratings for C and D groups surpass-ing those for B group(P<0.001).The TAS,TAA,and SSAAmax exhibited a decreasing pattern on T1WI-IDEAL images across A,B,C,and D groups,with statistically significant variances observed among all groups(P<0.001).Moreover,the SNR of the medulla oblongata layer in D group displayed a notably higher value compared to A,B groups,with statistically significant distinctions(P<0.001).Conclusion By combining the reduction of the echo train length(ETL)to 2 with the implementation of a double shimming,the occurrence of WFS-SA on nasopharyngeal T1WI-IDEAL enhanced examination images can be minimized and the overall image quality can be enhanced.

Polycystic ovary syndrome （PCOS）， a common reproductive endocrine disorder in women， is one of the leading causes of ovulatory infertility in women of reproductive age. Due to its heterogeneous etiology， complex symptoms， and challenging treatment， PCOS has become a focal point of research in gynecological and reproductive medicine globally. The pathogenesis of PCOS is complex and may involve regulatory mechanisms such as inflammatory responses， oxidative stress， and cellular autophagy. Crown-like structures （CLSs） refer to pro-inflammatory microenvironments formed by macrophages engulfing adipocytes. The inflammatory disorders induced by CLSs are one of the key factors contributing to the development of PCOS and its complications. Current studies have indicated that the obese status in PCOS accelerates the formation of CLSs， and the density of CLSs can predict the progression of metabolic disorders and influence the outcomes of various metabolic diseases. Traditional Chinese Medicine （TCM） offers the unique advantages of a holistic view， four diagnostic methods， and syndrome differentiation and treatment to ameliorate the symptoms and signs of PCOS through multiple levels， pathways， and targets. Although studies on the mechanisms of metabolic diseases and CLS formation have been reported in China and abroad， there is still a lack of literature on the correlation between CLSs and PCOS， as well as reviews on TCM interventions targeting CLSs for treating this disease. Therefore， this paper summarized the correlation between obese PCOS and CLSs and reviewed recent studies on TCM interventions based on CLS formation （adipose tissue-macrophage inflammatory crosstalk） in the treatment of obese PCOS， aiming to provide new research perspectives for the prevention and treatment of PCOS using TCM.
