Objective To investigate the clinical characteristics of patients with clinical and subclinical Cushing's syndrome caused by primary bilateral macronodular adrenal hyperplasia(PBMAH).Methods A retrospective analysis was performed on the clinical data of 198 patients with Cushing's syndrome caused by PBMAH diagnosed in the First Medical Center of Chinese PLA General Hospital from January 2004 to October 2024.According to clinical manifestations,the patients were classified into clinical type Cushing's syndrome(n=61)and subclinical type Cushing's syndrome(n=137),and the clinical characteristics of the two types were compared.Results The mean age at diagnosis of patients with PBMAH-induced Cushing's syndrome was(53.5±10.4)years,including 118 males and 80 females,with a male-to-female ratio of 1.475:1.Compared with the subclinical type,the clinical type had a higher proportion of females,higher levels of serum cortisol,24-hour urine free cortisol(24 h UFC),and inhibited serum cortisol after low-dose dexamethasone suppression.Additionally,the clinical type had lower plasma ACTH,larger adrenal nodules and a higher risk of surgery(P<0.05)compared with those in subclinical type.The incidences of hypertension,dyslipidemia,obesity,diabetes mellitus,hypokalemia,vitamin D deficiency,osteoporosis,coronary heart disease,and cerebrovascular disease in patients with Cushing's syndrome caused by PBMAH were 87.9%,50.5%,37.1%,36.9%,27.8%,25.9%,18.7%,18.7%and 12.1%,respectively.Among them,compared with subclinical type patients,clinical type patients had higher incidence of hypokalaemia,vitamin D deficiency and osteoporosis(P<0.05),while there were no statistically significant differences in the incidences of other comorbidities between the two types(P>0.05).The results of postoperative follow-up for PBMAH patients showed that the short-term biochemical remission rate of unilateral total adrenalectomy was 41.5%(22/53)and the long-term biochemical remission rate was 32.0%(8/25).The short-term biochemical remission rate of unilateral partial(or nodular)adrenalectomy was 52.9%(9/17),and the long-term biochemical remission rate was 14.3%(1/7).All patients who underwent unilateral total adrenalectomy plus contralateral partial resection developed adrenal insufficiency(3/3),and 1 patient(1/3)relapsed 3.4 years after surgery.Conclusion Clinical and subclinical types of Cushing's syndrome caused by PBMAH have their distinct clinical characteristics.Surgery is an effective treatment for PBMAH,but a certain proportion of patients fail to achieve biochemical remission after non-bilateral total adrenalectomy.

This paper summarizes the progress of theoretical research and practice of One Health in China,and discusses the paradigm of One Health governance to improve the prevention and control of infectious diseases in China and the world,and provide an example for the improvement of the public health system.In particular,China has long history to apply the concept of One Health in the national schistosomiasis control programmes and patriotic health campaigns,which were not only focusing on human health,but also emphasizing the sustainable development of animal health and ecological environment.At the same time,the application of tools such as system dynamics model,eDNA technology,One Health economic assessment and global One Health index(GOHI)in the field of disease control and environmental health provides technical support for the concept of One Health.Despite the challenges of practical application of these tools,the One Health concept will play a greater role in providing sustainable solutions for human-animal-environmental health by strengthening interdisciplinary collaboration,improving standardization protocols and promoting inter-national cooperation.

With the rapid advancement of artificial intelligence(AI)technology,its applications in the medical field have been expanding significantly.In the realm of hematopathological diagnosis,the advent of whole slide imaging(WSI)technology has paved the way for AI-based automatic slide reading,which is gradually transforming traditional diagnostic approaches.By establishing and training sophisticated algorithm models,AI,particularly deep learning and machine learning,can accurately and swiftly identify and analyze abnormal cells or tissues,as well as correctly inter-pret immunohistochemical staining results.This not only alleviates the workload of hematopathologists but also shortens the reporting cycle.As a result,it holds substantial application value in the fields of bone marrow pathology and bone marrow cell morphology diagnosis.Moreover,AI also demonstrates broad potential in the analysis of results from flow cytometry,chromosome karyotyping,and next-generation sequencing.Overall,the integration of AI technology is of great significance in propelling the development of intelligent diagnosis in hematopathology.This article aims to provide a comprehensive review of the application of AI in hematopathological diagnosis,and to explore its current status and future prospects.

Bone marrow biopsy is one of the important means of hematopathological diagnosis, which has decisive diagnostic significance for various benign and malignant lymphohematopoietic system diseases. Its diagnostic value includes morphological observation, immunohistochemistry, genetics, and molecular biology testing. Owing to the unique nature of bone marrow biopsy, decalcification is an essential step in the pre-treatment process. Its purpose is to remove calcium from bone tissue, preserve intact collagen fiber components, facilitate tissue sectioning, and prevent tissue detachment during staining. If bone marrow biopsy lacks sufficient decalcification, preparing a section is difficult. Conversely, if decalcification is excessive, it can seriously disrupt tissue antigen activity. Therefore, a decalcification method with high decalcification efficiency and mild antigen damage is essential for bone marrow biopsy. This article introduces a bone marrow biopsy tissue decalcification method with high efficiency and less antigen loss: decalcification is performed at room temperature with 12% formic acid and 8% hydrochloric acid decalcification solution on a shaker.

OBJECTIVE To observe the effect of a short course of oral glucocorticoids(GCs)on the expression level of tight junctions(TJs)in the epithelium of nasal polyps.METHODS Patients with chronic rhinosinusitis with nasal polyps(CRSwNP)who were hospitalized for nasal endoscopic surgery were recruited and given oral GCs for 7 consecutive days before surgery.Nasal polyp tissues were harvested before and after GCs treatment respectively.Adult patients who were to undergo nasal endoscopic surgery due to non-inflammatory diseases were selected,and the mucosa of the middle turbinates,inferior turbinates,or uncinate process obtained during surgery was retained as normal controls.Real-time PCR and immunofluorescence confocal microscopy were used to detect the expression of TJs.RESULTS Before oral GCs therapy,the mRNA expression levels of claudin-3,claudin-4,and occludin in nasal polyp specimens were significantly lower than that of normal nasal mucosa.After a short course of oral GCs therapy,the mRNA expression levels of claudin-3 and claudin-4 in nasal polyp specimens were significantly higher than those before treatment.After oral GCs treatment,the protein expression levels of claudin-1 and claudin-4 in nasal polyp tissues were significantly higher than those before treatment.CONCLUSION Compared with normal nasal mucosa,the expression of multiple tight junction proteins in the epithelium of nasal polyps decreases.Short-term oral GCs therapy can significantly up-regulate the expression of tight junction proteins.

OBJECTIVE To analyze the differences in clinical and imaging characteristics of patients with respiratory epithelial adenomatoid hamatoma(REAH)and nasal polyps(NP)whose lesions are located in bilateral olfactory cleft regions,so as to provide evidence for clinicians in the preoperative differential diagnosis of REAH and NP.METHODS Patients with bilateral olfactory cleft REAH,who underwent nasal endoscopic surgery from June 2006 to August 2023 in Beijing Tongren Hospital,were retrospectively analyzed as the REAH group.Patients with bilateral olfactory cleft NP who underwent nasal endoscopic surgery from January 2023 to October 2023 in Beijing Tongren Hospital were included and set as the NP group.The demographic and clinical characteristics,as well as the sinus CT data were analyzed to explore the intergroup differences.RESULTS Both the REAH group and the NP group included 155 patients.The REAH group was dominated by older men,and the prevalence of comorbid asthma was lower than that in the NP group(P<0.05).In the REAH group,the middle turbinate width,the superior turbinate width,the ratio of middle turbinate width/orbital board width,the ratio of superior turbinate width/middle orbital board width,and the maximum angle between the middle turbinate and nasal septum were significantly higher than those in the NP group(P<0.05).CONCLUSION Sinus CT examination can help clinicians identify REAH lesions before surgery,which is conducive to the formulation and implementation of treatment plans.
