AIM:To investigate the expression levels of serum sirtuin 6(Sirt6)and nicotinamide adenine dinucleotide phosphate oxidase 2(NOX2)in patients with primary glaucoma and their correlation with the severity of the disease. METHODS:This study is a cross-sectional study. Patients diagnosed with primary glaucoma at the hospital from August 2022 to June 2025 were enrolled and divided into mild-to-moderate and severe groups based on the mean deviation of visual field defects, along with healthy individuals as a control group. Clinical data were collected, and serum levels of Sirt6 and NOX2 were measured using enzyme-linked immunosorbent assay(ELISA). Correlations between serum Sirt6 and NOX2 levels and clinical parameters were analyzed. Multivariate Logistic regression was used to identify factors influencing disease severity, and the diagnostic efficacy of serum Sirt6 and NOX2 levels was evaluated using receiver operating characteristic(ROC)curves. RESULTS:A total of 120 patients with primary glaucoma(58 males, 62 females, mean age 60.08±8.19 y)and 100 controls(46 males, 56 females, mean age 60.23±8.67 y)were enrolled in this study. There were no statistically significant differences in sex or age between the two groups(both P>0.05). The intraocular pressure and serum NOX2 expression level in the primary glaucoma group were significantly higher than those in the control group, while the Sirt6 level was significantly lower than in the control group(all P<0.001). The AUC values of serum Sirt6 and NOX2 in the diagnosis of primary glaucoma were 0.733 and 0.770, respectively, with optimal cutoff values of 2.35 and 4.25 ng/mL, respectively. The AUC of the combined diagnosis of the two was 0.901, and its efficacy was obviously better than that of a single indicator(Zcombination-Sirt6=5.317, Zcombination-NOX2=4.720, P<0.001).The severe group had lower serum Sirt6 expression levels(P<0.05), and higher NOX2 expression levels(P<0.05)than the mild-to-moderate group. Serum Sirt6 expression levels were prominently negatively correlated with mean intraocular pressure(r=-0.354, P<0.05); NOX2 expression levels were prominently positively correlated with mean intraocular pressure(r=0.240, P<0.05). Multivariate Logistic regression analysis showed that a decrease in serum Sirt6 expression levels(OR=0.229, 95%CI: 0.090-0.581), an increase in serum NOX2 expression levels(OR=2.649, 95%CI: 1.658-4.232), an increase in mean intraocular pressure(OR=1.278, 95%CI: 1.118-1.462)which were risk factors for the progression to severe glaucoma. The AUC values of serums Sirt6 and NOX2 expression levels in diagnosing severe primary glaucoma were 0.794 and 0.800, respectively, the AUC, sensitivity, and specificity of the combined diagnosis of the two were 0.916, 80.00%, and 89.33%, respectively, and the combined diagnostic efficacy was better than that of a single indicator(Zcombination-Sirt6=2.627, P=0.009, Zcombination-NOX2=2.762, P=0.006). CONCLUSION:The decreased serum Sirt6 and increased NOX2 expression levels in patients with primary glaucoma are significantly correlated with disease severity, and the combined detection demonstrates good diagnostic value for primary glaucoma and its severity.

OBJECTIVE To analyze the potential adverse drug interactions(pADIs)of clarithromycin,and establish refined prescription pre-review rules.METHODS Outpatient prescriptions of clarithromycin in combination with other drugs were collected from January 1,2024 to June 30,2024 through hospital information system of the Third People's Hospital of Bengbu.pADIs were identified and their risk severities were graded according to Lexicomp and Micromedex databases.Then,refined prescription pre-review rules for clarithromycin pADIs-related drugs were established according to the identification and risk level results.RESULTS Among 3 046 clarithromycin combined drug prescriptions,946 cases of pADIs occurred in 812 prescriptions.There were 6,415 and 525 cases classified as"contraindicated","major"and"moderate",respectively.The combination drugs with"contraindicated"levels were tamsulosin,rupatadine,domperidone and ticagrelor,while those with"major"levels were mainly theophylline,dexamethasone and amlodipine.Accordingly,26 refined rules were established,including 4 items of"warning information→prescription interception",11 items of"warning information→prescription double signature"and 11 items of"attention information→prescription approval".CONCLUSIONS There are"contraindicated"and"major"risks associated with clarithromycin and its combination drugs in the hospital,and refined prescription pre-review rules for clarithromycin combined drug prescription have been established successfully.

Objective:This study aimed to retrospectively analyze the clinical characteristics and prognosis of patients with acute leukemia in the plateau.Methods:The clinical information of patients diagnosed with acute leukemia from February 2010 to April 2023 at the People's Hospital of Tibet Autonomous Region was reviewed and collected, including blood cell count, morphology, immunophenotype, cytogenetics, and molecular data. Survival analysis was conducted to analyze the outcome of patients with acute leukemia.Results:This study enrolled 105 patients with acute leukemia, including 24 with acute lymphoblastic leukemia (ALL), 62 with acute myeloid leukemia (AML), and 19 with acute leukemia without baseline data. Of the patients with ALL, 11 underwent bone marrow testing for immunophenotype, all of whom were B-cell lineage. The main FAB subtype of patients with AML was M 2 (25/57), followed by M 3 (12/57), M 5 (6/57), M 4EO (5/57), M 1 (4/57), M 4 (4/57), and M 0 (1/57). The complete remission rates of patients with ALL, acute promyelocytic leukemia (APL), and AML (non-APL) after one course of induction therapy were 57.1% (8/14), 100% (6/6), and 53.6% (15/28), respectively. The median event-free survival (EFS) and overall survival (OS) for patients with ALL were 2 (95% CI 0-9) and 3 (95% CI 0-9) months, respectively, with a median followup of 37 (95% CI 17-57) months. Patients with APL did not reach median EFS or OS, whereas the median EFS and OS for core binding factor AML (CBF-AML) cases were 10 (95% CI 0-21) months and 13 (95% CI 3-23) months, respectively, and patients with non-CBF-AML had inferior median EFS (2 months, 95% CI 1-3) and OS (2 months, 95% CI 1-3) ( P<0.01). Patients with ALL treated from 2020 to 2023 demonstrated trends toward better EFS ( P=0.16) and OS ( P=0.10) than those treated from 2010 to 2019. Similarly, trends toward superior EFS ( P=0.27) and OS ( P=0.12) were observed in patients with AML treated from 2016 to 2023, in comparison with those treated from 2010 to 2015. Conclusion:Progress in the treatment and prognosis of patients with acute leukemia in the plateau has been observed in recent years, which can be further promoted by precision diagnosis and tailored regimens.

Nine cases of mesenteric desmoid-type fibromatosis were diagnosed and treated in Taizhou Hospital, Wenzhou Medical University between January 2010 and May 2022, including 2 females and 7 males, aged 16 to 59 years. The lesions were in the mesentery of small intestine with 7 cases, ileocecal junction with 1 cases and transverse colon with 1 case. The tumors had an unclear boundary and no envelope, the section was solid, gray and tough. The mean maximum diameter was (10.7±8.5) cm (range 3.5-33.0 cm). Microscopically, fusiform fibroblasts and myofibroblasts were parallel, bunched or staggered, buried in a large amount of extracellular collagen. The cell morphology was relatively consistent, without obvious atypia, and mitosis was rare. Immunohistochemistry showed that the tumor cells were positive for vimentin (9/9), β-catenin (9/9), while smooth muscle actin (5/9) stains were focally positive. Ki-67 proliferation index was 1%-10%. Cytokeratin Pan, S-100, STAT6, CD117, DOG1, CD34, desmin and anaplastic lymphoma kinase stains were negative. Genetic analysis showed that there were 7 cases of c.121G>A(p.Thr41Ala) mutation of CTNNB1 gene, 1 case of c.121G>A(p.Thr41Ala) and 1 case of c.134C>T(p.Ser45Phe) double mutation, and 1 case of wild type. Tumors were surgically resected in all 9 cases. Eight cases had no recurrence or metastasis, 1 case had recurrence 6 months later, and no recurrence or metastasis after additional surgical resection.

Objective:To observe the multimodal imaging characteristics of tamoxifen retinopathy.Methods:A retrospective case study. From January 2019 to December 2021, 4 patients (8 eyes) with tamoxifen retinopathy diagnosed in Tangshan Eye Hospital were included in the study. All patients were female, with sick binoculus. The age was 59.5±4.6 years. After breast cancer resection, tamoxifen 20 mg/d was taken orally consecutively, including 1, 1, and 2 cases who took tamoxifen orally for 5, 7, and ≥10 years. All eyes were examined by fundus color photography, optical coherence tomography (OCT), OCT angiography (OCTA), fundus fluorescein angiography (FFA), and fundus autofluorescence (AF). The multi-mode image features of the fundus of the affected eyes were observed.Results:The yellow white dot crystal like material deposition in the macular area was observed in all eyes. In fundus AF examination, macular area showed patchy strong AF. FFA examination showed telangiectasia and fluorescein leakage in macular area at late stage. OCT showed that punctate strong reflexes could be seen between the neuroepithelial layers in the macular region with the formation of a space between the neuroepithelial layers, the interruption of the elliptical zone (EZ), and the formation of a hole in the outer lamella including 4, 5 and 3 eyes; The thickness of ganglion cells in macular region decreased in 7 eyes. OCTA showed that the blood flow density of the superficial retinal capillary plexus around the arch ring was decreased, and the retinal venules were dilated in 2 eyes; Deep capillary plexus (DCP) showed telangiectasia.Conclusion:Deposition of yellowish white dot like crystals can be seen in the macular region of tamoxifen retinopathy; dotted strong reflex between neuroepithelial layers, cavity formation, thinning of ganglion cell layer, EZ middle fissure and outer lamellar fissure; DCP capillaries and venules around the arch were dilated; telangiectasia in macular region; flaky strong AF in macular region.

OBJECTIVES: At present, there are many studies on Crohn's disease of terminal ileum and colon, but few studies on Crohn's disease of small intestine alone. This study aims to analyze the clinical features and therapeutic effect of small bowel in adult patients with Crohn's disease so as to strengthen the diagnosis and treatment for this disease. METHODS: From July 1, 2015 to October 31, 2018, patients with small bowel Crohn's disease at Department of Gastroenterology, Third Xiangya Hospital of Central South University, were enrolled. At the same time, patients' demographics and clinical data were collected. RESULTS: A total of 44 patients were small bowel Crohn's disease. Among them, 40 patients were male. The age at diagnosis was (35.8±10.3) years old and disease duration was (35.2±59.5) months. The subtypes included 29(65.9%) of ileum, 7(15.9%) of jejunum, 8(18.2%) of ileum with jejunum. There were 27(61.4%) of stricture behavior, 4(9.1%) of penetrating behavior, and 13(29.5%) of non-stricture and non-penetrating behavior. Endoscopic visible stricture (29/85, 34.1%) was common, followed by longitudinal ulcers (27/85, 31.8%). Non-caseate granulomatous were found in 2 cases (4.5%). The score of Crohn's disease activity index was correlated to hemoglobin, hematocrit, and erythrocyte sedimentation rate (all CONCLUSIONS Patients with ileum account for a large proportion in patients with small bowel Crohn's disease. Stricture is more common in small bowel Crohn's disease. Stricture and longitudinal ulcer are more common under enteroscopy. Crohn's disease activity index is correlated to hemoglobin, red blood cell specific volume, and erythrocyte sedimentation rate. The most common complication is intestinal obstruction. Mesalazine is less effective on small bowel Crohn's disease.
