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.

The medicinal use of Malvae Semen has a long history. In this paper， by consulting the ancient materia medica， prescription， agronomy， literature and other aspects of the classics， the name， origin， evolution of scientific name， quality， harvesting and processing， functions and indications and others of Malvae Semen were systematically sorted out and verified， so as to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shennong Bencaojing began to use Dongkuizi as the correct name， which was used in the past dynasties， and there were also aliases such as Kuicaizi， Huacai， and Kuizi. Through the original research， it can be seen that Kuicai is the mainstream original plant of Malvae Semen， that is， Malva verticillata var. crispa， the Alcea rosea and M. cathayensis are also used. In modern times， the seeds of Abutilon theophrasti have been passed off as Malvae Semen， while the seeds of M. verticillata var. crispa have rarely been used in medicine. And Abutili Semen has been another medicinal material with different efficacy since the collection of Newly Revised Materia Medica in the Tang dynasty. Since the Ming and Qing dynasties， the cultivation of Kuicai has been decreasing， while A. theophrasti is more common and easy to obtain， and Abutili Semen and Malvae Semen are similar in morphology and confused， which should be corrected. In addition， Malvae Fructus is a Mongolian customary medicinal herb， which is different from the traditional use of seeds in traditional Chinese medicine. Kuicai， as an important vegetable in history， was widely cultivated and gradually shrunk after the Song dynasty， it is now mainly produced in southern provinces. The quality evaluation of Malvae Semen is better for those with dry bodies， full grain， grayish brown color， no mud， and no impurities. The harvesting is generally in the autumn and winter. After drying， it is seeded， sieved peel and impurities， mashed， or slightly stir-fried to yellow-white color with gentle fire. It is sweet， cold and slippery in nature and taste， with the main effects of laxation， diuresis， lactation and elimination of swelling. The efficacy of Abutili Semen is clearing heat and removing toxicity， promoting diuresis and removing nebula， the efficacy is quite different from that of Malvae Semen. Based on the results of textual research， it is suggested that M. verticillata var. crispa should be used as the medicinal source of Malvae Semen in the development of famous classical formulas， the corresponding processing methods should be selected according to the requirements of drug processing in the formulas， while the raw products are recommended to be used if the processing is not specified.

Head and neck squamous cell carcinoma (HNSCC) is a tumor characterized by immunosuppressive tumor microenvironment (TME) and poor prognosis. Its complex immune evasion mechanisms are primarily related to T cell dysfunction and the suppression of anti-tumor immune responses. Immunotherapy aims to modulate the patient’s immune system to recognize and eliminate tumor cells, thereby achieving therapeutic goals. Studies have demonstrated that the TME plays a pivotal role in HNSCC pathogenesis, facilitating tumorigenesis, progression, and therapy resistance, ultimately contributing to adverse clinical outcomes. Advances in technology have deepened understanding of the TME, paving the way for novel therapeutic interventions in HNSCC. This review comprehensively summarizes the efficacy and safety of TME-targeted immunotherapies, integrating evidence from published clinical trials, while proposing insights for future research to develop more effective therapeutic strategies.

Objective To investigate the utility of dual-energy CT combined with musculoskeletal ultraso-nography in differentiating between calcium pyrophosphate deposition disease and gouty arthritis.Methods A retro-spective analysis was conducted on the medical records of 102 patients diagnosed with gouty arthritis and 102 patients diagnosed with calcium pyrophosphate deposition disease.These patients were categorized into the Gout group and Calcium Deposition group,respectively,based on their respective diagnoses.All patients underwent dual-energy CT and musculoskeletal ultrasonography examinations,while joint fluid aspiration results or intra-articular crystal material served as the gold standard for diagnosis.The diagnostic efficacy of dual-energy CT and musculoskeletal ultrasonography in discriminating between calcium pyrophosphate deposition disease and gouty arthritis was evalu-ated.Results In the gout group,the proportion of male patients and serum uric acid levels were significantly higher compared to those in the calcium deposition group(P<0.05).The prevalence rates of knee joint,first metatarsopha-langeal joint,and ankle joint involvement were higher in the gout group,while knee joint,wrist joint,and shoulder joint involvement rates were higher in the calcium deposition group.The proportions of irregular bone cortex,carti-lage injury,and degenerative meniscus changes were lower in the gout group compared to the calcium deposition group(P<0.05).The proportions of double contour sign,tophus formation,hyperechoic band within ligaments or tendons,and bone erosion were higher in the gout group compared to the calcium deposition group(P<0.05),whereas cartilage calcification was lower in the gout group(P<0.05).The sensitivities for diagnosing calcium pyrophosphate deposition disease and gouty arthritis using dual-energy CT scan alone,musculoskeletal ultrasound alone,and their combined use were 86.27%,83.33%,and 94.12%respectively.The specificities for diagnosing these conditions using dual-energy CT scan alone,musculoskeletal ultrasound alone,and their combined use were 89.22%,88.24%,and 86.27%respectively.The positive predictive values were 88.89%,87.63%,and 87.27%,respectively.The negative predictive values were 86.67%,84.11%,and 93.63%,respectively.The accuracies were 87.75%,85.78%,and 90.20%respectively.The agreement Kappa values were 0.755,0.716,and 0.804 respectively.Conclusions The integration of dual-energy CT and musculoskeletal ultrasonography exhibits promising diagnostic efficacy in discriminating between calcium pyrophosphate deposition disease and gouty arthritis.This combined approach serves as a valuable adjunctive tool for the diagnosis of both conditions.

OBJECTIVE To identify the key genes associated with lymph node metastasis in head and neck squamous carcinoma(HNSCC)and construct a prognostic model based on The Cancer Genome Atlas(TCGA)database.METHODS Differentially expressed genes(DEGs)between tumor tissues and normal tissues in the HNSCC dataset in the TCGA database were screened by R software,and gene modules related to lymph node metastasis were screened by weighted gene co-expression network(weighted gene co-expression network analysis,WGCNA).Prognostic risk models were constructed by univariate cox regression and Lasso regression analyses.Survival analyses and ROC curves were performed to verify the Reliability of prognostic models.CIBERSORT,TIMER and ESTIMATE algorithms analysed the differences in the tumor micro environment(TME)of different risk groups.RESULTS There were 2 565 DEGs screened,and a set of gene modules highly correlated with disease prognosis and lymph node metastasis were obtained by WGCNA analysis,and correlation analysis verified that the expression of genes in this gene module was highly correlated with lymph node metastasis.Univariate cox regression and Lasso regression were used to identify 6 key prognostic genes:CDKN2A,CCNE2,KNSTRN,AURKA,KPNA2,and ORC1.A prognostic model was constructed based on the 6 genes,and survival analysis showed that the prognosis of the high-risk group was significantly worse than that of the low-risk group(P<0.0001).The ROC curves demonstrated the good predictive performance of this prognostic model.CIBERSORT analyses revealed differences in the immune microenvironment of tumors in different risk groups.CONCLUSION The 6 key prognostic genes screened were helpful in predicting the prognosis of HNSCC patients and were closely associated with the immune microenvironment of HNSCC,suggesting that they may serve as potential therapeutic targets.

Abstract: This study aims to find out the causes for the dissolution of unqualified samples found during evaluation sampling of lansoprazole enteric-coated preparations by the laser infrared imaging system and orbitrap high resolution mass spectrometry, with suggestions for improvement. Lansoprazole enteric-coated preparations were tested by current standard, the dissolution of a batch of samples was below the limit and other items were in line with the standard. Considering that this product is unstable to acid and alkali, the following exploratory experiments were designed from different dimensions, based on the conclusion of the unannounced inspection of the company, to explore the reasons for the unqualified batch, including the influence of high-temperature and high-humidity storage environment on the key quality properties of the sample, the influence of 2-hour acid resistance test on dissolution result, the imaging of the core and the measure of coating layer thickness, the optimization of chromatographic conditions of related substances, and the analysis of the source of impurities. It was found that improper storage in circulation and poor coating process caused the low dissolution of this batch: the high-temperature and high-humidity storage environment possible in the circulation process led to the decreasing efficacy of disintegrating agent in the samples and thus the difficulty to release the active pharmaceutical ingredient fully; the coating solution could not be uniformly sprayed on the core, resulting in thin isolation layer and different thickness, which then affected the protection of the main drug against acid degradation. The above two reasons together resulted in unqualified dissolution of this batch. The overall quality of lansoprazole enteric-soluble preparation is good, but the formulation and process in some companies need to be optimized; and the temperature and humidity in the circulation process need to be controlled in strict accordance with the regulations.

OBJECTIVE To assess the efficacy of bioabsorbable steroid-releasing sinus stents for improving surgical outcomes and subjective symptoms when placed in the bilateral frontal sinus opening(FSO)following full functional endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps(CRSwNP).METHODS CRSwNP patients who had under full functional endoscopic sinus surgery with complete data of nasal endoscopy and sinus computed tomography data were identified and included in the study.The patients were divided into a control group consisting of patients receiving only full functional endoscopic sinus surgery(n=92)and a stent group consisting of patients receiving full functional endoscopic sinus surgery combined with placement of steroid implants in both FSO(n=38).The visual analogue scale(VAS)subjective symptom scores and surgical outcomes were compared preoperatively,and on postoperative day(PD30 and PD90)between the two groups.RESULTS Compared to baseline,the overall symptom VAS scores of patients after operation decreased significantly in both groups(P<0.05),and the degree of improvement of overall symptoms in the stent group was significantly better than in the control group(P<0.05).On PD30,the proportion of patients requiring postoperative interventions for bilateral FSO was reduced by 42.3%in the stent group,and was significantly lower than in the control group(P<0.05).Compared to the control group,the proportion of patients needing postoperative intervention in both ethmoid sinus on the stent group decreased by 17.7%(P>0.05).The results at PD90 were consistent with those at PD30.CONCLUSION Full functional endoscopic sinus surgery in combination with bilateral frontal sinus stent implantation is better than full functional endoscopic sinus surgery alone.

Here, we report a previously unrecognized syndromic neurodevelopmental disorder associated with biallelic loss-of-function variants in the RBM42 gene. The patient is a 2-year-old female with severe central nervous system (CNS) abnormalities, hypotonia, hearing loss, congenital heart defects, and dysmorphic facial features. Familial whole-exome sequencing (WES) reveals that the patient has two compound heterozygous variants, c.304C>T (p.R102*) and c.1312G>A (p.A438T), in the RBM42 gene which encodes an integral component of splicing complex in the RNA-binding motif protein family. The p.A438T variant is in the RRM domain which impairs RBM42 protein stability in vivo. Additionally, p.A438T disrupts the interaction of RBM42 with hnRNP K, which is the causative gene for Au-Kline syndrome with overlapping disease characteristics seen in the index patient. The human R102* or A438T mutant protein failed to fully rescue the growth defects of RBM42 ortholog knockout ΔFgRbp1 in Fusarium while it was rescued by the wild-type (WT) human RBM42. A mouse model carrying Rbm42 compound heterozygous variants, c.280C>T (p.Q94*) and c.1306_1308delinsACA (p.A436T), demonstrated gross fetal developmental defects and most of the double mutant animals died by E13.5. RNA-seq data confirmed that Rbm42 was involved in neurological and myocardial functions with an essential role in alternative splicing (AS). Overall, we present clinical, genetic, and functional data to demonstrate that defects in RBM42 constitute the underlying etiology of a new neurodevelopmental disease which links the dysregulation of global AS to abnormal embryonic development.
