Objective: To explore the impact of sleep quality, experience of childhood maltreatment, and their interaction on depressive symptoms among middle school students, so as to provide the reference for early intervention of depressive symptoms among middle school students. Methods: From September to December 2023, a questionnaire survey was conducted among 1 231 students from two secondary schools in Harbin, Heilongjiang Province by a convenient sampling method. The survey included general demographic information, Childhood Trauma Questionnaire Short Form, Pittsburgh Sleep Quality Index and Short Version of Center for Epidemiological Studies Depression Scale. The Chi square test was used to analyze the differences in depressive symptom, sleep quality and childhood maltreatment among students with different demographic characteristics. Correlation analysis was conducted using Logistic regression, and interaction analysis was performed by both additive and multiplicative interaction models. Results: The detection rate of depressive symptoms among middle school students was 22.7%, and the rate for high school students (35.2%) was significantly higher than that for middle school students (17.0%) ( χ 2=50.35, P <0.01). The detection rates of depressive symptoms among middle school students with a history of childhood maltreatment and poor sleep quality were 45.8% and 44.0%, respectively. Multivariate Logistic regression analysis showed that compared to students without a history of childhood maltreatment, students with a history of childhood maltreatment had a higher risk of depressive symptoms ( OR =4.49，95% CI =3.31~ 6.09 , P <0.01);students with poor sleep quality had a higher risk of depressive symptoms than students with good sleep quality ( OR = 5.99，95% CI =4.37~8.22, P <0.01).The interaction results showed that the presence of childhood maltreatment and poor sleep quality had an additive interaction on the occurrence of depression in middle school students. Compared with students without childhood maltreatment and having good sleep quality, students with childhood maltreatment and poor sleep quality had a 22.49 times higher risk of developing depression ( OR =22.49，95% CI =14.22~35.59, P <0.01). Conclusion Depressive symptoms among middle school students are associated with childhood maltreatment and poor sleep quality, and there is an additive interaction between childhood maltreatment and poor sleep quality on the impact of depressive symptoms.

Objective To explore the prognostic value of glycolysis-related genes in colorectal cancer (CRC) patients and formulate a novel glycolysis-related prognostic risk model. Methods Single-cell and bulk transcriptomic data of CRC patients, along with clinical information, were obtained from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. Glycolysis scores for each sample were calculated using single-sample Gene Set Enrichment Analysis (ssGSEA). Kaplan-Meier survival curves were generated to analyze the relationship between glycolysis scores and overall survival. Novel glycolysis-related subgroups were defined among the cell type with the highest glycolysis scores. Gene enrichment analysis, metabolic activity assessment, and univariate Cox regression were performed to explore the biological functions and prognostic impact of these subgroups. A prognostic risk model was built and validated based on genes significantly affecting the prognosis. Gene Set Enrichment Analysis (GSEA) was conducted to explore differences in biological processes between high- and low-risk groups. Differences in immune microenvironment and drug sensitivity between these groups were assessed using R packages. Potential targeted agents for prognostic risk genes were predicted using the Enrichr database. Results Tumor tissues showed significantly higher glycolysis scores than normal tissues, which was associated with a poor prognosis in CRC patients. The highest glycolysis score was observed in epithelial cells, within which we defined eight novel glycolysis-related cell subpopulations. Specifically, the P4HA1⁺ epithelial cell subpopulation was associated with a poor prognosis. Based on signature genes of this subpopulation, a six-gene prognostic risk model was formulated. GSEA revealed significant biological differences between high- and low-risk groups. Immune microenvironment analysis demonstrated that the high-risk group had increased infiltration of macrophages and tumor-associated fibroblasts, along with evident immune exclusion and suppression, while the low-risk group exhibited higher levels of B cell and T cell infiltration. Drug sensitivity analysis indicated that high-risk patients were more sensitive to Abiraterone, while low-risk patients responded to Cisplatin. Additionally, Valproic acid was predicted as a potential targeted agent. Conclusion High glycolytic activity is associated with a poor prognosis in CRC patients. The novel glycolysis-related prognostic risk model formulated in this study offers significant potential for enhancing the diagnosis and treatment of CRC.

The OsSPL10 gene has previously been reported to positively regulate trichome development and negatively regulate salt and drought stress tolerance in rice. However, it is not clear whether this gene can be used for gene editing to create new germplasm of glabrous leaf and salt-tolerant rice. In this study, we created six rice mutants by CRISPR/Cas9-mediated editing of OsSPL10 from 'Xinfeng 2', 'Xinkedao 31', and 'Xindao 25', the main rice cultivars along the Yellow River. Visual observation and scanning electron microscopy verified that the mutants lacked trichomes on the leaves and glumes, and the expression of glabrous marker genes OsHL6, OsGL6, and OsWOX3B in mutants was down-regulated compared with that in the wild type. The net photosynthetic rate, stomatal conductance, and transpiration rate of flag leaves in the mutants were significantly higher than those in the wild type. In addition, the survival rates of the mutants were much higher than that of the wild type after 7 days of treatment with 200 mmol/L NaCl. The results of quantitative real-time polymerase chain reaction (qRT-PCR) further verified that compared with the wild type, the mutants demonstrated down-regulated expression of the salt stress-related gene OsGASR1 and up-regulated expression of OsNHX2 and OsIDS1. Statistical analysis of agronomic traits showed that the mutants had increased plant height and no significant changes in yield-related traits compared with the wild type. The six spl10 mutants created in this study not only had glabrous leaves and glumes but also demonstrated enhanced tolerance to salt stress, serving as new germplasm resources for directional breeding of rice along the Yellow River.

Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.

IDD models were established in all groups except for the sham surgery group. After successful modeling, the sham surgery group and IDD group were given physiological saline by gavage, while the kidney tonifying and blood activating formula group was given 1.5 g/ml of kidney tonifying and blood activating formula by gavage for 3 consecutive weeks. QRT-PCR was used to detect the expression levels of circ0036763 and miR-583 in the nucleus pulposus cells of mice in each group, MTT was used to detect cell proliferation, and Western blot was used to detect the expression of PCNA, collagen Ⅰ, and collagen Ⅱ proteins.Results:The expression level of circ_0036763 in IDD nucleus pulposus cells decreased, while the expression level of miR-583 increased (all P<0.05); Overexpression of circ_0036763 can promote proliferation and extracellular matrix synthesis of nucleus pulposus cells (all P<0.05); Circ_0036763 targets miR-583 and upregulates miR-583 reversible overexpression. Circ_0036763 enhances the proliferation and extracellular matrix synthesis ability of IDD nucleus pulposus cells. Compared with the sham surgery group, the IDD group showed an increase in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels decreased (all P<0.05); Compared with the IDD group, the Kidney Tonifying and Blood Activating Formula group showed a decrease in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels increased (all P<0.05). Conclusions:The kidney tonifying and blood activating formula (Bushen Huoxue) may induce proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.

Objective:To explore the method of obtaining the key parameters of the average value articulator in healthy people based on mandibular movement trajectory data, with a view to providing a reference for the clinical application of the average value articulator.Methods:One hundred healthy volunteers (42 males and 58 females) with individual normal occlusion, aged 18-55 years old, who met the inclusion criteria were recruited from Beijing, and their mandibular movement trajectory data were collected. The left and right sagittal condylar inclination(SCI) and transversal condylar inclination(TCI) were obtained from the values of the articulator parameters which were generated in the mandibular movement analysis system.The SCI and TCI were grouped by gender and calculated separately for the two groups and the overall sample; the gender differences in the two parameters and the differences between the mean values of the two parameters and the average value articulator empirical values (35° for SCI and 15° for TCI) for the overall sample were compared.Results:The differences between SCI (35.8°±7.4°) and TCI [11.2° (11.3°)] in males and the corresponding parameters [35.6°±8.3° and 10.8° (9.5°), respectively] in females were not statistically significant ( t=0.10, P=0.922; Z=-0.60, P=0.552); the overall sample SCI (35.7°±7.9°) did not differ statistically from the average value articulator empirical value ( t=1.23, P=0.221), and the overall sample TCI [10.9° (10.3°)] was significantly smaller than the average value articulator empirical value ( W=5 825.00, P<0.001). Conclusions:The mandibular movement trajectory data of 100 adults with individual normal occlusion in this study shows that the gender factor does not affect the setting of the key parameters of the average value articulator, the SCI of the average value articulator empirical values is appropriate, and the TCI has the possibility of being on the large side. In the clinical use of the articulator to assist in the design of restorations, the parameter values should be rationally adjusted according to the actual situation of the patient′s dentition and mandibular movement.

ObjectiveTo observe the clinical effect of Qingxin Zishen decoction on hot flashes after endocrine therapy for prostate cancer and explore its therapeutic mechanism. MethodA total of 60 patients who met the criteria and were admitted to Jiangsu Province Hospital of Chinese Medicine from December 2021 to December 2022 were collected and randomly divided into a treatment group and a control group， with 30 cases in each group. The treatment group was treated with Qingxin Zishen decoction， while the control group was only given routine nursing. The observation period of this study was eight weeks. The improvement of hot flash frequency， hot flash degree， hot flash score， ISS score， and TCM syndrome score were observed in the two groups before and after treatment. The changes of serum endothelin-1 （ET-1）， nitric oxide （NO）， calcitonin gene-related peptide （CGRP）， prostate specific antigen （PSA）， and testosterone were detected. ResultIn terms of efficacy， after treatment， the frequency， degree， and score of hot flashes， ISS score， and TCM syndrome score decreased in the treatment group （P<0.05）. Compared with the control group， all indicators were better in the treatment group （P<0.05）. In terms of laboratory indicators， after treatment， the serum NO level in the treatment group was increased. ET-1 level was decreased. The ratio of ET-1/NO was decreased， and the CGRP level was decreased （P<0.05）. However， testosterone and PSA levels were not significantly changed . Compared with the control group， after treatment， the serum NO level in the treatment group was higher， and the level of ET-1 was lower. The ratio of ET-1/NO and the CGRP level were lower （P<0.05）. There were no significant differences in testosterone and PSA levels between the two groups. ConclusionQingxin Zishen decoction can significantly improve hot flashes in patients with prostate cancer after endocrine therapy. The mechanism of Qingxin Zishen decoction may be to improve the vasomotor function by regulating the expression level of vasomotor factors， so as to treat hot flashes.

Objective:To investigate the clinical efficacy of simultaneous arthroscopic repair of anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) for treating chronic lateral ankle instability (CLAI) in conjunction with subtalar instability (STI).Methods:This is a retrospective case series study. The clinical data of 15 patients with ankle arthroscopic in the Department of Hand and Foot Surgery, the Second Affiliated Hospital of Soochow University from January 2019 to December 2022 were analyzed retrospectively. There were 11 male cases and 4 female cases, aged (28.6±1.5) years (range: 19 to 39 years). All the patients were evaluated by manual inversion stress X-ray and MRI before operation. Arthroscopically observing and then repairing the ATFL and CFL separately after further diagnostic confirmation. One year after operation, MRI was performed, and pain visual analogue score(VAS), American Orthopedic Foot and Ankle Society ankle hindfoot scale (AOFAS-AH) and Karlsson ankle functional scale(KAFS) were evaluated. Data were compared using paired sample t test. Results:The follow-up period was (23.6±2.3) months (range: 12 to 30 months). At last follow-up,the VAS decreased from 6.1±1.4 preoperatively to 1.4±1.2( t=9.482, P<0.01).The AOFAS-AH improved from 50.5±11.7 preoperatively to 94.2±6.1( t=-13.132, P<0.01), and the KAFS improved from preoperatively 44.3±10.8 to 90.8±6.4 ( t=-12.510, P<0.01). There was no complication such as recurred instability or joint stiffness. Conclusions:Arthroscopically repairing the ATFL and CFL separately can effectively restore the stability of the ankle and subtalar joint with small trauma. Patients can recover quickly after surgery. It provides a new idea for the clinical treatment of CLAI combined with STI.

Objective To investigate the characteristics and clinicopathology of v-raf murine sarcoma viral oncogene homolog Bl(BRAF)V600E mutations in papillary thyroid carcinoma(PTC)in Air Force flight personnel.Methods Data of cases and test results of BRAF V600E mutation were collected from Air Force aviators pathologically diagnosed with PTC.A univariate analysis of the relationship between BRAF V600E mutations and clinicopathologic features was performed.Results The overall rate of BRAF V600E mutations among 55 PTC flight crew members was 70.91％.The univariate analysis showed that the number of lymph node metastases in the BRAF V600E mutated group was larger than in the BRAF V600E unmutated group,and the proportion of BRAF V600E mutations in flight crews at intermediate risk of recurrence was higher than that in those at low risk of recurrence(P＜0.05).The presence or absence of BRAF V600E mutations did not affect the results of medical evaluation of PTC in flight personnel.Conclusion The rate of PTC BRAF V600E mutations in Air Force flight crews is similar to that of the general Chinese population.BRAF V600E mutations are associated with an increased number of lymph node metastases and risk of recurrence,and follow-up is recommended for flight personnel with PTC,especially those with BRAF V600E mutations.
