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.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

AIM: To investigate the differences of myopia and ocular biological parameters of primary and middle school students in Urumqi.METHODS: A cross-sectional survey. A total of 2 495 primary and middle school students aged 7 to 18 from 4 schools in Urumqi were selected by judgemental sampling from September 2021 to November 2021 for relevant eye examination. The differences of ocular biological parameters and refractive status of students of different ages, genders and nationalities were compared, and the correlation between spherical equivalent(SE)and ocular biological parameters was analyzed.RESULTS: The detection rate of poor vision among the students was 80.36%, the detection rate of myopia was 55.91%, and the detection rate of astigmatism was 42.96%, among which the detection rate of low myopia was 63.80%, the detection rate of moderate myopia was 27.60%, and the detection rate of high myopia was 8.60%. There were significant differences in the detection rate of poor vision, myopia, astigmatism, SE and some ocular biological parameters among students of different ages and nationalities(all P<0.05). Among them, the detection rate of myopia, astigmatism and poor vision among Uygur and Kazakh ethnic groups was significantly lower than that of Han. The detection rate of poor vision and myopia among boys was lower than that among girls, while the detection rate of astigmatism was higher than that of girls. Spearman correlation analysis showed that axis length of eye, axial length to axial ratio, anterior chamber depth, and pupil diameter were negatively correlated with SE(rs=-0.664, -0.724, -0.320, -0.086, all P<0.001), and lens thickness was positively correlated with SE(rs=0.147, P<0.001).CONCLUSION: The prevalence of myopia among primary and secondary school students in Urumqi is high, and there are differences in the distribution of ocular biological parameters among children and adolescents of different ages and ethnicities.

Gastric cancer (GC) is one of the most common malignant tumors worldwide, and most of the patients are diagnosed at the advanced stage. Most of the treating options are comprehensive treatment, in which immunotherapy plays more and more important role. Melanoma antigen-associated gene-A (MAGE-A) family is a kind of cancer testis antigens. Except in germ cells of testis and trophoblast cells of placenta, MAGE-A family is highly expressed in cancerous tissues and participates in a variety of biological processes, such as cancer cell proliferation, differentiation and metastasis. In addition, cancer testis antigen also possesses good immunogenicity, which can induce humoral and cellular immune responses, is a good target for immunotherapy, and has good application value in the diagnosis, treatment and prognosis of GC. A variety of targeted therapeutic drugs based on MAGE-A are in phase I or II clinical trials, it has good safety and potential clinical application value. With the continuous progress of clinical trials and basic research on MAGE-A targets in GC, it is expected to provide a theoretical basis for clinical transformation and immunotherapy of MAGE-A in the future.
