Objective: To study the correlation between short sleep duration and screening myopia among primary and middle school students in Beijing, so as to provide a scientific basis for the comprehensive prevention and control of myopia among students. Methods: Using a stratified cluster random sampling, 25 593 primary and middle school students from 16 districts of Beijing were selected from September to November 2023. The National Common Diseases and Health Influencing Factors Monitoring Survey Questionnaire was used to conduct a questionnaire survey, and visual acuity was tested according to the Specification for the Screening of Refractive Error in Primary and Middle School Students. The reporting rates of short sleep duration and detection rates of screening myopia among primary and middle school students were compared using the Chi square test. Binary Logistic regression was used to analyze the correlation between short sleep duration and screening myopia. Results: About 68.63% of students reported short sleep duration. There was a statistically significant difference in the reporting rate of short sleep duration among students in different school stages ( χ 2=981.18, P <0.01), with the lowest reporting rate of vocational high school students (47.07%) and the highest reporting rate of ordinary high school students (76.17%). The detection rates of screening myopia among primary school students ( 57.09% ) and middle school students (76.53%) who reported short sleep duration were higher than those who reported enough sleep duration (52.65%, 71.94%), with satistically significant differences ( χ 2=14.83, 17.96, P <0.01). The results of binary Logistic regression analysis showed that primary and middle school students with short sleep duration had a higher risk of developing screening myopia, compared to students with enough sleep duration ( OR =1.25); after adjusting for confounding factors such as educational stage, gender, region, boarding situation, primary and secondary school students with short sleep duration still had a higher risk of screening myopia ( OR =1.26) ( P <0.01). The analysis results stratified by educational stage showed that primary school students from grades 4-6 and middle school students with short sleep duration had a higher risk of screening myopia ( OR=1.18, 1.20, P <0.01). Conclusions Primary and secondary school students in Beijing with short sleep duration sleep have a higher risk of developing screening myopia. Families, schools, and society should ensure enough sleep duration to reduce the occurrence of myopia among students.

BACKGROUND: Enzalutamide, a second-generation androgen receptor (AR) pathway inhibitor, is widely used in the treatment of castration-resistant prostate cancer. However, after a period of enzalutamide treatment, patients inevitably develop drug resistance. In this study, we characterized leucine-rich repeated G-protein-coupled receptor 5 (LGR5) and explored its potential therapeutic value in prostate cancer. METHODS: A total of 142 pairs of tumor and adjacent formalin-fixed paraf-fin-embedded tissue samples from patients with prostate cancer were collected from the Pathology Department at Sun Yat-sen Memorial Hos-pital. LGR5 was screened by sequencing data of enzalutamide-resistant cell lines combined with sequencing data of lesions with different Gleason scores from the same patients. The biological function of LGR5 and its effect on enzalutamide resistance were investigated in vitro and in vivo . Glutathione-S-transferase (GST) pull-down, coimmunoprecipitation, Western blotting, and immunofluorescence assays were used to explore the specific binding mechanism of LGR5 and related pathway changes. RESULTS: LGR5 was significantly upregulated in prostate cancer and negatively correlated with poor patient prognosis. Overexpression of LGR5 promoted the malignant progression of prostate cancer and reduced sensitivity to enzalutamide in vitro and in vivo . LGR5 promoted the phosphorylation of glycogen synthase kinase-3β (GSK-3β) by binding heat shock protein 90,000 alpha B1 (HSP90AB1) and mediated the activation of the Wingless/integrated (WNT)/β-catenin signaling pathway. The increased β-catenin in the cytoplasm entered the nucleus and bound to the nuclear AR, promoting the transcription level of AR, which led to the enhanced tolerance of prostate cancer to enzalutamide. Reducing HSP90AB1 binding to LGR5 significantly enhanced sensitivity to enzalutamide. CONCLUSIONS LGR5 directly binds to HSP90AB1 and mediates GSK-3β phosphorylation, promoting AR expression by regulating the WNT/β-catenin signaling pathway, thereby conferring resistance to enzalutamide treatment in prostate cancer.

The genome tagging project (GTP) plays a pivotal role in addressing a critical gap in the understanding of protein functions. Within this framework, we successfully generated a human influenza hemagglutinin-tagged sperm-specific protein 411 (HA-tagged Ssp411) mouse model. This model is instrumental in probing the expression and function of Ssp411. Our research revealed that Ssp411 is expressed in the round spermatids, elongating spermatids, elongated spermatids, and epididymal spermatozoa. The comprehensive examination of the distribution of Ssp411 in these germ cells offers new perspectives on its involvement in spermiogenesis. Nevertheless, rigorous further inquiry is imperative to elucidate the precise mechanistic underpinnings of these functions. Ssp411 is not detectable in metaphase II (MII) oocytes, zygotes, or 2-cell stage embryos, highlighting its intricate role in early embryonic development. These findings not only advance our understanding of the role of Ssp411 in reproductive physiology but also significantly contribute to the overarching goals of the GTP, fostering groundbreaking advancements in the fields of spermiogenesis and reproductive biology.

OBJECTIVE: To investigate the clinical characteristics and prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). METHODS: Clinical data of 10 patients with PTCL-NOS in Gansu Provincial Hospital from May 2016 to June 2023 were collected. The treatment outcomes were evaluated, and the factors affecting prognosis were analyzed. RESULTS: The median age of onset for the 10 patients was 60.7 (47-75) years, with 7 males and 3 females. Nine cases received chemotherapy, while one case died suddenly after diagnosis, and the median course of chemotherapy was 6.9 (1-13) courses. Assessing the efficacy, 3 patients achieved complete remission (CR) while 7 patients showed progression. Age, sex, lactate dehydrogenase (LDH) level, Ki-67 and the presence of hemophagocytic lymphohistocytosis (HLH) were not statistically correlated with CR rate ( P >0.05). Patients with IPI score 3-5, and Ann Arbor stage III-IV had statistically lower CR rates (both P <0.05). Age, B symptoms, LDH level ,hemoglobin, Ki-67 index and PLR value were not statistically correlated with overall survival (OS) time ( P >0.05). Male, platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, presence of HLH, NLR≥4.05, and LMR <2.81 were statistically correlated with shorter OS (all P <0.05). Among the 10 patients, 3 cases have survived and are still in CR status, while 7 cases have died, with a median survival time of 7.5 (1-85) months. CONCLUSIONS Patients with IPI score 3-5 and Ann Arbor stage III-IV have low CR rate and poor prognosis. The OS of patients who are male, with platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, complication of HLH, NLR≥4.05, and LMR <2.81 is short, and prognosis is poor.

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with hemophagocytic lymphohistiocytosis (HLH). METHODS: Clinical data of 78 patients with HLH admitted to Gansu Provincial People's Hospital from January 2014 to May 2023 were collected, and the correlation between relevant indicators and patient prognosis was analyzed. RESULTS: Among the 78 HLH patients, there were 48 males and 30 females, with a median age of onset of 48 (1-84) years old; 26 patients were treated with chemotherapy, 44 patients were treated with glucocorticoids, immunoglobulin or cyclosporine, 5 patients received symptomatic treatment, 1 patient received plasma exchange, and 2 patients refused treatment. By the end of the follow-up, there were 39 survivors, 35 deaths, and 4 patients lost to follow-up. There was no significant correlation between sex, ferritin, triglycerides, hemophagocytosis, bone marrow cellularity, Epstein-Barr virus (EBV) infection, SUV value of PET-CT, alanine aminotransferase (ALT), interleukin-6 (IL-6), platelet-to-lymphocyte ratio (PLR) and overall survival (OS) of the patients (P >0.05). Patients with age≥60 years, neutrophil-to-lymphocyte ratio (NLR) >0.59, red cell distribution width-to-platelet ratio (RPR) >0.30, lymphocyte-to-monocyte ratio (LMR)≤2.74, red blood cell distribution width (RDW)>16.45%, tumor-associated HLH, aspartate aminotransferase (AST)≥148 U/L, procalcitonin (PCT)≥0.66 ng/ml, neutrophils (NEU) <2×10⁹/L, fibrinogen (FIB)<1.85 g/L, lactate dehydrogenase (LDH)≥1 740 U/L, hemoglobin (Hb)<85 g/L, platelet (PLT)<57×10⁹/L had significantly shorter OS, with statistical significance (P < 0.05). Multivariate analysis showed that LMR≤2.74, RDW>16.45%, LDH≥1 740 U/L, and NEU<2×10⁹/L were independent risk factors affecting OS in HLH patients (P < 0.05). CONCLUSION Some blood-based inflammatory markers are significantly associated with OS in patients with HLH. NLR, RPR, LMR, RDW and PCT can be used to assess the prognosis of HLH patients, and RDW and LMR are independent factors affecting OS of HLH patients, which provide greater predictive value for prognosis. Hypercellular bone marrow in HLH patients may indicate a poor prognosis.

OBJECTIVE: To explore the effect of Lactobacillus reuteri on testicular injury in mice exposed to neonicotinoid insecticides (NNI). METHODS: Fifteen C57BL/6 male mice were randomly divided into control group (CTRL group), exposure group (NNI group) and Lactobacillus intervention group (NNI-L group). The mice in CTRL group were given 0.02ml/g of 0.5% carboxymethyl cellulose sodium solution by gavage for 14 days. The mice in NNI group were given 0.02 ml/g of NNI mixture by gavage for 14 days. The mice in NNI-L group were given 0.02 ml/g of NNI mixture by gavage and 5×108cfu/ml of Lactobacillus reuteri powder solution for 14 days. Then, the histomorphology and function of testicle were evaluated by hematoxylin-eosin staining, immunofluorescence staining and RNA sequencing. RESULTS: Compared with CTRL group, the thickness of testicular seminiferous epithelium in the NNI group was significantly thinner. And the decline in the number of spermatogenic cells and sperm was observed. And the expression of spermatogonial stem cell marker UCHL1 was down-regulated which was significantly improved in NNI-L group compared with the NNI group. The abnormal expressions of hormone and sperm methylation related genes in testis of NNI group were detected by RNA sequencing, with significant down-regulation being found in NPFF and IGF2. While the expression of HSD3B8 was significantly up-regulated. The abnormal expression of these genes could be significantly improved after oral administration of Lactobacillus reuteri. CONCLUSION Testicular spermatogenesis and endocrine function can be damaged by NNI exposure. And oral administration of Lactobacillus reuteri protects testis from the adverse effects of NNI toxicity.

Objective: To analyze high myopia and dioptre changes in middle school students in Beijing from 2019 to 2022, so as to provide a basis for formulating preventive and control measures. Methods: Using stratified cluster random sampling, 16 districts of Beijing were divided into four groups, each of which was respectively composed of 83, 83, 84, and 84 middle schools, in order to examine non cycloplegic auto refraction among the senior grades 1 to 3 students from September to October in each year (from 2019 to 2022). Finally, the dataset results of each of the four groups (21 589, 21 161, 21 561, 21 123) were compared by the Chi square test and trend Chi square test. Trend changes were evaluated by annual percentage change (APC). Results: The rates of high myopia were higher in female students than in males from 2019 to 2022 (15.60%,14.59%; 15.33%, 14.44%; 14.65 %, 14.17%; 14.63%,13.84%), and the difference in 2019 was statistically significant ( χ 2=4.93, P <0.05). The rates of high myopia in middle school students in urban areas were significantly higher than those in rural areas(16.45%, 13.78%; 16.81 %, 13.00%; 15.84%, 13.06%; 15.85%, 12.72%), and the differences were statistically significant ( χ 2=30.18, 60.43, 33.92 , 42.23, P <0.05). With the increase of grade, the rates of high myopia increased ( χ 2 trend =674.56, 608.38, 655.21, 676.89, P <0.05), with junior grade 3 students being the most robust. The rate of high myopia in middle school students from 2019 to 2022 decreased from 15.09 to 14.22%, with an average annual rate of 2.08% ( APC=-2.08, t=-7.99, P ＜0.05). The refractive error of high myopia middle school students in 2019 and 2022 were -7.44(-10.25, -6.00) and -7.38(-10.00, -6.00)D, respectively, with no statistically significant difference ( H=4.30, P >0.05). Conclusions The rate of high myopia in middle school students in Beijing shows a decreasing trend, but it remains at a high level. It is necessary to classify the prevention and control strategy, and standardize the measures in order to manage early onset, high incidence rates, and severe myopia.
