OBJECTIVES: To explore the mediating role of sleep duration in the relationship between depression symptoms and myopia among middle school students. METHODS: This study was a cross-sectional research conducted using a stratified cluster random sampling method. A total of 1 728 middle school students were selected from two junior high schools and two senior high schools in certain urban areas and farms of the Xinjiang Production and Construction Corps. Questionnaire surveys and vision tests were conducted among the students. Spearman analysis was used to analyze the correlation between depression symptoms, sleep duration, and myopia. The Bootstrap method was employed to investigate the mediating effect of sleep duration between depression symptoms and myopia. RESULTS: The prevalence of myopia in the overall population was 74.02% (1 279/1 728), with an average sleep duration of (7.6±1.0) hours. The rate of insufficient sleep was 83.62% (1 445/1 728), and the proportion of students exhibiting depression symptoms was 25.29% (437/1 728). Correlation analysis showed significant negative correlations between visual acuity in both eyes and sleep duration with depressive emotions as measured by the Center for Epidemiologic Studies Depression Scale (with correlation coefficients of -0.064, -0.084, and -0.199 respectively; P<0.01), as well as with somatic symptoms and activities (with correlation coefficients of -0.104, -0.124, and -0.233 respectively; P<0.01) and interpersonal relationships (with correlation coefficients of -0.052, -0.059, and -0.071 respectively; P<0.05). The correlation coefficients for left and right eye visual acuity and sleep duration were 0.206 and 0.211 respectively (P<0.001). Sleep duration exhibited a mediating effect between depression symptoms and myopia (indirect effect=0.056, 95%CI: 0.029-0.088), with the mediating effect value for females (indirect effect=0.066, 95%CI: 0.024-0.119) being higher than that for males (indirect effect=0.042, 95%CI: 0.011-0.081). CONCLUSIONS Sleep duration serves as a partial mediator between depression symptoms and myopia in middle school students.

OBJECTIVE: To investigate the clinicopathological features and differential diagnosis of male genital system lymphoma (MGSL). METHODS: We retrospectively analyzed the clinicopathological and immunophenotypic features and prognosis of 80 cases of MGSL. RESULTS: The onset age of the MGSL patients ranged from 4 to 85 (median 62) years old. All the cases showed non-specificity of the imaging features and clinical manifestations. MGSL was located mainly in the testis (n = 66), followed by the prostate (n = 7), epididymis (n = 3), scrotum (n = 3) and penile glans (n = 1). Diffused large B cell lymphoma (DLBCL) was the most common pathological type (n = 62), next came extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) (n = 7) and other rare types (n = 12). During the 1－112-month follow-up of 10 of the 19 patients, 1 died at 1 month after diagnosed with prostatic B-lymphoblastic lymphoma (B-LBL) and another 1 died at 50 months after diagnosed with testicular DLBCL. CONCLUSION MGSL is rare clinically, mainly of the DLBCL type pathologically, lacking specificity in clinical symptoms and imaging manifestation. The definite diagnosis of the malignancy depends on histopathology combined with related molecular examination and immunohistochemical labeling, and R-CHOP chemotherapy is the first choice for its treatment.

Objective To propose a high-precision deep learning-based image assessment method of osteosarcoma chemotherapy efficacy for clinical treatment,as existing methos have low accuracy of osteosarcoma assessment.Methods The low incidence of osteosarcoma led to the small scale of its imaging data and the problem of imbalance in data categories.This study combined deep learning with clinical medical information,combined the bone sarcoma generation module of BoneGAN and the scale lesion information capture module,and proposed OMLA-Net,a deep learning assessment network for chemotherapy effect of bone sarcoma based on multi-scale lesion attention network,which achieved computer-aided bone tumor assessment with integrated data augmentation and focused lesion information through pre-training and generalized loss training.Results In this study,40 cases of osteosarcoma MRI data were used as the basis for the comparison test on the generated dataset,and the OMLA-Net assessment outperformed the SOTA method Conv-LSTM-GAN in terms of the assessment effects such as accuracy and F1 scores,and the difference was statistically significant(Bootstrap statistical method P＜0.05);the subsequent K-fold cross-validation ablation experiments further demonstrated the effectiveness of each module proposed by OMLA-Net.Conclusion OMLA-Net can effectively perform the impact assessment of chemotherapy effect on osteosarcoma,which provides a new idea for subsequent clinical application.

Objective To observe the efficacy and safety of Xiaoying Sanjie Granules(derived from the modified Sini San and Banxia Houpo Decoction)in the treatment of patients with benign thyroid nodules of qi stagnation and phlegm obstruction type.Methods A retrospective study was conducted.According to the treatment methods,60 patients with benign thyroid nodules of qi stagnation and phlegm obstruction type were divided into observation group and control group,30 cases in each group.The control group was given health training alone,and the observation group was given oral use of Xiaoying Sanjie Granules on the basis of treatment for the control group.The course of treatment covered 12 weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,maximum cross-section diameter of the thyroid nodule and thyroid function indexes of thyroid stimulating hormone(TSH),free triiodothyronine(FT3)and free thyroxine(FT4)in the two groups before and after treatment were observed.After treatment,the clinical efficacy and adverse reactions were compared between the two groups.Results(1)After 12 weeks of treatment,the total effective rate of the observation group was 73.33%(22/30),and that of the control group was 10.00%(3/30).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.01).(2)After treatment,the TCM syndrome scores of the observation group were significantly lower than those before treatment(P＜0.01),and the maximum cross-section diameter of the thyroid nodule was significantly smaller than that before treatment(P＜0.01).However,no obvious improvement of TCM syndromes and the maximum cross-section diameter of the thyroid nodule was presented in the control group(P＞0.05).The intergroup comparison showed that the decrease of TCM syndrome scores and the reduction of the maximum cross-section diameter of the thyroid nodule in the observation group were significantly superior to those in the control group(P＞0.05).(4)During the treatment,no obvious adverse reactions occurred in the two groups,indicating high safety.Conclusion Xiaoying Sanjie Granules exerts certain effects on patients with benign thyroid nodules of qi stagnation and phlegm obstruction type.The granuels are effective on significantly reduce the maximum cross-section diameter of the thyroid nodule,improve the clinical symptoms of patients,and has fewer adverse reactions,with high safety.

RNA m6A modification is mainly regulated by m6A methyltransferase,m6A demethylase and m6A binding protein,which can change gene transcription and thus regulating physiological and patholog-ical processes.In recent years,more and more evidences have shown that m6A methylation plays an im-portant role in the regulation of tumor microenvironment(TME).It can affect the occurrence,develop-ment and metastasis of various types of cancer.Myeloid-derived suppressor cells(MDSCs),a group of immature myeloid cells,are important immune cells in TME which can be pathologically activated.It mainly inhibits the activity of T cells,so as to promote the immune escape of malignant tumors.Studies have shown that MDSC,a new and promising target for immunotherapy,can reshape the immunosuppres-sive microenvironment and modulate the efficacy of cancer immunotherapy.The role of m6A modification in the activation,differentiation and effector function of some immune cells has been widely concerned.However,the research on how m6A modification affects MDSC is still very limited.Therefore,it is par-ticularly important to further explore the relationship between them.Based on the introduction of MDSC and RNA m6A modification,this review summarizes the mechanism and research progress of RNA m6A modification in regulating MDSC in TME in order to provide new strategies for targeting MDSC from the perspective of epigenetic modification.

ObjectiveThe detection of RNA single nucleotide polymorphism (SNP) is of great importance due to their association with protein expression related to various diseases and drug responses. At present, splintR ligase-assisted methods are important approaches for RNA direct detection, but its specificity will be limited when the fidelity of ligases is not ideal. The aim of this study was to create a method to improve the specificity of splintR ligase for RNA detection. MethodsIn this study, a dual-competitive-padlock-probe (DCPLP) assay without the need for additional enzymes or reactions is proposed to improve specificity of splintR ligase ligation. To verify the method, we employed dual competitive padlock probe-mediated rolling circle amplification (DCPLP-RCA) to genotype the CYP2C9 gene. ResultsThe specificity was well improved through the competition and strand displacement of dual padlock probe, with an 83.26% reduction in nonspecific signal. By detecting synthetic RNA samples, the method demonstrated a dynamic detection range of 10 pmol/L-1 nmol/L. Furthermore, clinical samples were applied to the method to evaluate its performance, and the genotyping results were consistent with those obtained using the qPCR method. ConclusionThis study has successfully established a highly specific direct RNA SNP detection method, and provided a novel avenue for accurate identification of various types of RNAs.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the pathological damage to and inflammation of different intestinal segments in a rat model of severe hemorrhage,and to explore the effect of polarization of intestinal macrophage on the pathophysiology of intestinal inflammation.Methods Male Wistar rats were randomly divided into two groups:the sham operation group and hemorrhage group.In the hemorrhage group,40％of the total blood volume was lost in 25-30 minutes,while in the sham operation group,only the femoral artery and vein were intubated without bleeding.The rats were killed at 0,3,6,12 and 24 hours.The entire intestine was isolated quickly,and sections of the intestine were cut at the duodenum,jejunum,ileocecal junction,colon and rectum for histopathological evaluation.ELISA was adopted to determine related inflammation factors while multi-color immunohistochemistry was used to calculate macrophage surface markers.The data was statistically analyzed.Results(1)Compared with the sham group,there was no significant difference in colon histology at 3 h and 6 h,but significant difference was detected in rectum scores only at 24 h.The scores of other intestinal segments were significantly different at each time point.The severity of ileocecal and colonic lesions after bleeding increased with time.The duodenum,jejunum and ileocecum were more critically injured at 3 h than the rectum at 6 h.The injury to the duodenum,jejunum,ileum and colon was much more pronounced than to the rectum at 12 h.(2)The expressions of TNF-α and IL-1β in the rectum were increased significantly at 12 h post operation.The expressions of IL-1β,TNF-α in the jejunum increased obviously at 3 h and 6 h,respectively.(3)Three hours after severe bleeding,the level of macrophages in the jejunum and ileocececal area increased significantly,and the percentage of M1 macrophages was higher.After 6 hours,the proportion of M2 macrophages in the jejunum and M1 macrophages decreased significantly.After 3 hours,the percentage of M1 macrophages in the colon decreased,but that of M2 macrophages increased.The proportion of M2 polarized macrophages in the duodenum and rectum increased at 3 h after severe bleeding but decreased at 6 h.Conclusion Pathological damage to intestinal sections after bleeding varies depending on the time,and is correlated with the inflammatory level of macrophages.
