AIM: To investigate the effect of a new type of rhinodacryocystostomy combined with fluticasone propionate on patients with chronic dacryocystitis.METHODS: A total of 100 patients(100 eyes)with chronic dacryocystitis who admitted to our hospital between January 2021 and December 2022 were enrolled in the prospective study. The patients in the study were divided into a control group(n=50)and an observation group(n=50)based on their admission order and number. Patients in the control group were treated with novel rhinodacryocystostomy, while patients in the observation group were treated with a new type of rhinodacryocystostomy combined with fluticasone propionate. The preoperative and postoperative best corrected visual acuity(BCVA), quality of life score, and recurrence of chronic dacryocystitis were compared between the two groups of patients.RESULTS: All patients completed the postoperative 6 mo follow-up, and the total effective rate of patients in the observation group was better than that of patients in the control group(98% vs 84%, P=0.001). There was no significant difference in preoperative and postoperative BCVA between the two groups(P>0.05). Preoperatively, there was no significant difference in the quality of life scores between the two groups of patients(P>0.05); At 6 mo postoperatively, the quality of life scores of patients in the control group, including physical function, psychological function, social function, and material life status, were lower than those in the observation group(all P<0.001). There were 9 recurrences in the control group(18%)and 1 in the observation group(2%), and there was statistical significance in the postoperative recurrence rate between the two groups(χ2=-2.739, P=0.001).CONCLUSION: The new type of rhinodacryocystostomy combined with fluticasone propionate treatment for chronic dacryocystitis patients has a good therapeutic effect, can improve the quality of life of patients, and reduce the probability of disease recurrence.

Objective To establish a method for HPLC fingerprint analysis and determine three main components of Modified Zengye Decoction.Methods The chromatographic column was Shimadzu WondaSil C18 column(250 mm×4.6 mm,5 μm),the mobile phase was acetonitrile-0.3％aqueous phosphoric acid with a gradient elution procedure,the volume flow rate was 1.0 mL/min,the detection wavelengths were 265,203,310 and 290 nm,the column temperature was 25 ℃,and the injection volume was 20 μL.The HPLC fingerprints of the 10 batches of Modified Zengye Decoction were established,and the similarity analysis was performed by using the similarity evaluation system of chromatographic fingerprint of traditional Chinese medicine(version 2012A).The common peaks were identified and assigned,and the contents of the three main components were quantitatively determined.Results There were 17 common peaks in the fingerprints of 10 batches of Modified Zengye Decoction with similarities ranging from 0.872-0.989.The fingerprints recognized peak 9,14 and 17 as ferulic acid,aurantiamarin and harpagoside,respectively.The contents of ferulic acid,aurantiamarin and harpagoside were 0.067 3-0.174 8,0.498 8-1.522 7,0.270 9-0.802 4 mg/g,and the transfer rate were 30.74％-55.63％,11.77％-35.94％,23.15％-68.56％,respectively.Conclusion The established HPLC fingerprint analysis method combined with main components quantitative analysis method can be used for the quality analysis and control of Modified Zengye Decoction with simple analysis method and reliable results.

Thyroid cancer is the most common malignant tumor of the endocrine system,with differentiated thyroid carcinoma(DTC)accounting for over 90%.Most DTC patients have a good prognosis after systematic treatment,but a few develop dedifferentiation of primary tumor site or metastases,progressing to radioiodine-refractory DTC(RAIR-DTC),leading to significantly worse prognosis,which is a major cause of thyroid carcinoma-related mortality.Dysregulation of sodium iodide symporter(NIS)expression and function is the main reason for iodine-131 therapy resistance in thyroid carcinoma,influenced by genetic changes,epigenetic changes,tumor microenvironment,autophagy,and other factors.Genetic alterations such as the BRAFV600E mutation and RET/PTC chromosomal rearrangements activate oncogenic signaling pathways,directly or indirectly affecting NIS expression and its normal localization on the cell membrane.Epigenetic regulation modulates specific gene expression patterns,regulating NIS gene expression levels,thereby affecting the radioiodine uptake function of thyroid cells.Components in the tumor microenvironment,including immune cells,cytokines,and extracellular matrix,may also disrupt iodine uptake by reducing the expression levels of NIS and/or disrupting its normal function on the cell membrane.Additionally,autophagy,as an intracellular metabolic regulatory mechanism,can also modulate NIS expression and its intracellular distribution,thus impacting the radioiodine uptake and the sensitivity to iodine-131 therapy.Reviewing the roles of these factors in thyroid carcinoma dedifferentiation comprehensively can provide a more thorough understanding of the occurrence and progression of RAIR-DTC,aiding in the exploration of new therapeutic targets,improving prognosis,and providing more effective personalized treatment strategies for patients.

Objective:To investigate whether hsa_circ_0054595(circRTN4)is involved in glomerulosclerosis of lupus nephri-tis(LN)by regulating monocyte-derived TNF-α.Methods:RT-qPCR and immunofluorescence were used to detect the expression of TNF-α in monocytes of LN patients,and fluorescence in situ hybridization(FISH)was used to detect the expression of circRTN4.THP1 cells were transfected with circRTN4-siRNA and negative control NC-siRNA,respectively.RT-qPCR and Western blot were used to detect the expression of TNF-α in THP1cell,and ELISA was used to detect the expression of TNF-α in THP1 culture superna-tant.THP1 cells were transfected with mircoRNA mimics,and the expression of TNF-α was detected by Western blot.The direct bind-ing of miR-486-3p to TNF-α and circRTN4 were verified by reversion experiment and dual luciferase reporter gene experiment.MRL/lpr mice were injected with circRTN4 recombinant adeno-associated virus via tail vein,and the expression of circRTN4 in peripheral blood mononuclear cells of the mice was detected by RT-qPCR.ELISA was used to detect the expression of serum TNF-α.HE staining and PAS staining were used to observe the pathological changes,and immunofluorescence was used to detect the expression of FN.Results:The expressions of TNF-α and circRTN4 were increased in monocytes of LN patients(P<0.05).The expression of TNF-α in THP1 was significantly increased in the LN group(P<0.01).Knockdown of circRTN4 inhibited the expression and secretion of TNF-α(P<0.05),and this effect was achieved by binding to miR-486-3p(P<0.01).In vivo,knockdown of circRTN4 in peripheral blood monocytes of MRL/lpr mice reduced the expression of TNF-α in serum(P<0.05),and improved glomerular cell proliferation and FN deposition.Conclusion:Highly expressed circRTN4 in monocytes promotes the expression of TNF-α by binding to miR-486-3p,and participates in the occurrence and development of glomerulosclerosis in LN.

Neutrophils as the first immune responders to infection can quickly identify and eliminate pathogens. The mainly rely on glycolysis to exert their killing functions. Although researches on the metabolic shifs that affect neutrophil functions began early, little is known about how neutrophils undergo metabolic transformation during the anti-infection process. It has been proven that glycogen metabolism plays an important role in regulating the functions of neutrophils. Other metabolic pathways besides glycolysis, such as mitochondrial metabolism and fatty acid oxidation during neutrophil differentiation, have potential contributions to the regulation of neutrophils′ functions. This review summaries current studies about metabolic regulatory effects of neutrophils on anti-infection responses, intending to provide reference for further study on the metabolism of neutrophils.

Objective The existing evidence of exercise rehabilitation in patients undergoing surgery for valvular heart disease was analyzed,described and evaluated by using evidence mapping methods.Methods Systematic reviews and randomized controlled trials on exercise rehabilitation of patients undergoing valvular heart disease surgery were searched from CNKI,Wanfang Data,VIP,CBM,Embase,PubMed,Cochrane Library,Web of Science,Ovid,CINAHL and other databases,and the search period was established until April 23,2024.The quality of the included literature was evaluated,and the feature information of the included literature was visualized in the form of bubble map and table.Results Fifty-one literatures(including 44 randomized controlled trials and 7 systematic evaluations)were finally included.Among the 44 randomized controlled trials,the types of exercise were mainly related to anaerobic exercise(3 literatures),aerobic exercise(11 literatures),flexibility training(8 literatures),and multisport exercise(22 literatures);postoperative inpatient rehabilitation accounted for a relatively high proportion(16 literatures),followed by overall postoperative rehabilitation(13 literatures)and pre-operative prehabilitation(7 literatures).Twenty-seven conclusions were categorized as"beneficial",15 as"possibly beneficial,"and one ach as"unclear"and"no effect".Seven systematic evaluations were subjected to Meta-analysis,and in terms of the design of the included studies,there were only 3 systematic reviews that included randomized controlled trials.Of the study conclusions,three were"beneficial",three were"possibly beneficial"and one was"unclear".Conclusion The evidence mapping shows that exercise rehabilitation is generally beneficial or potentially beneficial in the rehabilitation of valvular heart disease surgery,mainly in the postoperative inpatient rehabilitation phase.High-quality studies are needed to further investigate the effectiveness of exercise programs with different intensities,frequencies,and durations,as well as different valve types,adverse effects of exercise,and other outcome indicators.

Clinical cases treated by magnetic compression anastomosis (MCA) for different causes and types of intestinal stenosis/ atresia to successfully achieve intestinal recanalization were reviewed, so as to explore the clinical application of MCA. From May 2019 to August 2022, 4 patients underwent colorectal MCA for intestinal recanalization in the First Affiliated Hospital of Xi'an Jiaotong University and Northwest Women and Children's Hospital. All operations went well, and the intestinal anastomosis was recanalized. The magnetic ring was discharged in 7-15 days, and the postoperative colonoscopy or radiography showed that the anastomosis was intact. MCA can be used to treat different types of colorectal stenosis and atresia due to different reasons, and can also be used to assist intestinal anastomosis in colorectal surgery.

BackgroundThere are differences in executive function between major depressive episode patients with or without psychotic symptoms， and childhood trauma may affect the executive function of patients with major depressive episode. Previous research studies predominantly focused on adult patients with major depressive episode， with a lack of studies specifically focusing on adolescent patients with major depressive episode. ObjectiveTo investigate the differences in executive function among adolescent patients with major depressive episode， with or without psychotic symptoms and childhood trauma. MethodsA total of 112 hospitalized adolescent patients with major depressive episode who met the criteria of the International Classification of Diseases， tenth edition （ICD-10） were included in the study. The participants were recruited from the Department of Child and Adolescent Psychiatry， Shenzhen Kangning Hospital during the period from August 2020 to November 2021. Additionally， 27 healthy controls were recruited through public advertisements. The Cambridge Neuropsychological Test Automated Battery （CANTAB） was used to assess executive function through the administration of the Motor Screening Task （MOT）， Spatial Working Memory（SWM） and Rapid Visual Information Processing （RVP） modules. Childhood Trauma Questionnaire-Short Form （CTQ-SF） was used to assess the trauma type. ResultsCompared with healthy controls， adolescent patients with major depressive episode had a longer mean delay （Z=-3.407， P=0.001） in the MOT task. In the SWM task， the patients had a higher total number of intergroup error responses （Z=-3.291， P=0.001）， a higher total number of intragroup error responses （Z=-3.461， P=0.001）， more total number of double error responses （Z=-3.218， P=0.001）， a higher total error responses （Z=-3.312， P=0.001）， higher strategy scores （Z=-2.437， P=0.015） and longer average delay time （Z=-2.055， P=0.040）. In the RVP task， the patients had fewer hits （Z=-3.196， P=0.001）， more misses （Z=-3.179， P=0.001）， fewer rejections （Z=-2.772， P=0.006）， lower hit probability （Z=-3.187， P=0.001） and lower A´ scores （Z=-3.070， P=0.002）.Compared with adolescent patients with major depressive episode without psychotic symptoms， those with psychotic symptoms had a lower total number of double error responses （Z=-2.566， P=0.010） in SWM task. Compared with adolescent patients with major depressive episode who did not experience emotional neglect， those who experienced emotional neglect had longer average delay time （Z=-3.183， P=0.001） in MOT task， fewer total hits （Z=-2.445， P=0.014）， more total missed reports （Z=-2.467， P=0.014）， lower hit probability （Z=-2.445， P=0.014） and lower A´scores （Z=-2.089， P=0.037） in RVP task. Adolescent patients with major depressive episode who had experienced emotional abuse had longer average delay time in MOT task than those who had not experienced emotional abuse （Z=-2.552， P=0.011）. ConclusionAdolescent patients with major depressive episode exhibit abnormalities in a majority of executive function domains. Specifically， those without psychotic symptoms and with childhood trauma demonstrate significantly impaired executive function. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGS013）， Basic and Applied Basic Research Fund of Guangdong Province （number， 2019A1515110047）， Shenzhen Science and Technology Planning Project （number， JCYJ20190809155019338）］
