ABSTRACT

Burkitt lymphoma is a highly aggressive B-cell lymphoma and the fastest proliferating human malignant tumor. If the disease is found in the early stage, the patient could have a high possibility to be cured successfully, whereas the prognosis is poor in the late stage. Burkitt lymphoma can occur in children and adults, and it is categorized as local (Africa), sporadic, and immunodeficiency associated type. Sporadic Burkitt lymphoma mainly affects children and adolescents, and the most common initial sites are abdominal organs and lymph nodes. Sporadic Burkitt lymphoma manifested by initial oral and maxillofacial lesions is relatively rare. Here, a case of pediatric sporadic Burkitt lymphoma, with oral and maxillofacial lesions as the first symptoms, was reported. The patient was treated in the Department of Periodontology, Shandong University School and Hospital of Stomatology. After timely checkup was provided, the patient was transferred to another hospital and had good results. In this article, an incidence of Burkitt lymphoma, with oral and maxillofacial lesions as the first symptom, was reviewed to provide reference for oral clinicians to achieve early diagnosis and treatment of patients with Burkitt lymphoma with oral diseases and improve the success rate of treatment.

ABSTRACT

d-Limonene is the predominant component of essential oil from Exocarpium Citri Grandis, known for its antibacterial, antioxidant, insecticidal, and anti-inflammatory properties. The synthesis, transport, and accumulation of d-limonene in Citrus grandis 'Tomentosa' fruits are regulated by limonene synthase (LS) and its associated regulatory genes. This study addresses the gap in understanding the spatiotemporal cytological changes of LS and its regulatory genes. Through cytochemical techniques, we investigated the distribution of essential oil in the plastids, endoplasmic reticulum, and vacuoles of secretory cavity cells. We identified the LS-encoding gene CgLS via transcriptomics and demonstrated in vitro that CgLS catalyzes the formation of d-limonene from geranyl diphosphate (GPP). Transient overexpression of CgLS increased monoterpene limonene accumulation, while TRV virus-induced gene silencing reduced it. CgLS expression levels and d-limonene content showed spatiotemporal consistency with fruit development, with in situ hybridization revealing predominant expression in secretory cavity cells. Immunocytochemical localization indicated that CgLS is primarily located in the endoplasmic reticulum, plastids, and vacuoles. Our findings suggest that CgLS is translated in the endoplasmic reticulum and transported to plastids and vacuoles where d-limonene synthesis occurs. This study provides comprehensive insights into the characteristics of CgLS and its role in d-limonene synthesis at the tissue, cellular, and molecular levels in C. grandis 'Tomentosa'.

ABSTRACT

BACKGROUND: Adolescent-specific ADHD self-report screening measures can greatly increase the likelihood of correct diagnosis and timely treatment of ADHD in adolescents. This study provides preliminary evidence for evaluating the reliability and validity of the Adult ADHD Self-Report Scale-Revised (ASRS-R) in a school-based sample of Chinese adolescents. METHODS: The ASRS-R and the Strengths and Difficulties Questionnaire (SDQ) were administered to 867 adolescents aged 12 to 16 years (Mage = 13.08 years). Construct validity was assessed using correlation analysis of the ASRS-R with the SDQ. Moreover, confirmatory factor analysis (CFA), internal consistency, retest reliability, and measurement invariance of the scales were examined by gender. RESULTS: CFA showed a two-dimensional factor structure of the ASRS-R, and the model fitted the data well (χ2/df = 4.370, RMSEA = 0.062, TLI = 0.932, CFI = 0.940, GFI = 0.927, AGFI = 0.907, and SRMR = 0.038). The ASRS-R scale was invariant across gender and had satisfactory internal consistency (Cronbach's alpha = .934) and test-retest reliability (intraclass correlation coefficient = .874). The construct validity, as calculated using the SDQ, was also acceptable. CONCLUSION: The ASRS-R can be a psychometrically reliable self-report instrument and provide preliminary support as a simple tool for identifying ADHD symptoms in Chinese adolescents. The findings provide evidence for extending the application of the ASRS, previously limited to adults, to the adolescent populations.

ABSTRACT

Delirium in critical ill patients is a complex and common neurological syndrome in the intensive care unit (ICU) that is caused by a range of structural or functional abnormalities. ICU Delirium is associated with reduced compliance, prolonged hospital stays, greater use or delayed withdrawal of sedatives, higher rates and durations of mechanical ventilation, and higher rates of mortality. The aetiology and pathogenesis of ICU delirium are unclear, and the lack of better prediction, prevention, and treatment measures leads to a non-standardized control of delirium. By searching the relevant literature, we aim in this narrative review to describe progress in the pathogenesis, predictive biomarkers, diagnosis, and treatment of ICU delirium.

ABSTRACT

BACKGROUND: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with unclear etiology. Growing evidence suggests the microbiome plays a role in SLE pathogenesis. However, findings are inconsistent across studies due to factors like small sample sizes and geographical variations. A comprehensive meta-analysis is needed to elucidate microbiome alterations in SLE. OBJECTIVE: This study aimed to provide a systematic overview of microbiota dysbiosis across body sites in SLE through a meta-analysis of alpha diversity indices, beta diversity indices, and abundance taxa of microbiome. METHODS: A literature search was conducted across four databases to identify relevant studies comparing SLE patients and healthy controls. Extracted data encompassed alpha and beta diversity metrics, as well as bacterial, fungal, and viral abundance across gut, oral, skin, and other microbiota. Study quality was assessed using the Newcastle-Ottawa Scale. Standardized mean differences and pooled effect sizes were calculated through meta-analytical methods. RESULTS: The analysis showed reduced alpha diversity and distinct beta diversity in SLE, particularly in the gut microbiota. Taxonomic analysis revealed compositional variations in bacteria from the gut and oral cavity. However, results for fungi, viruses, and bacteria from other sites were inconsistent due to limited studies. CONCLUSIONS: This meta-analysis offers a comprehensive perspective on microbiome dysbiosis in SLE patients across diverse body sites and taxa. The observed variations underscore the microbiome's potential role in SLE pathogenesis. Future research should address geographical variations, employ longitudinal designs, and integrate multi-omics approaches.

ABSTRACT

BACKGROUND: The prevalence of nonalcoholic fatty liver disease (NAFLD) in patients with chronic hepatitis B (CHB) has increased in recent clinical practice; however, the relationship between CHB and hepatic steatosis (HS) remains controversial. AIM: To shed light on the potential association between NAFLD and hepatitis B virus (HBV) infection. METHODS: We conducted a systematic literature search using multiple databases, including PubMed, the Cochrane Library, Web of Science, and EMBASE, to identify relevant studies. Predefined inclusion criteria were used to determine the eligibility of the studies for further analysis. RESULTS: Comprehensive meta-analysis software was used for statistical analysis, which covered 20 studies. The results indicated a lower NAFLD susceptibility in HBV-infected individuals (pooled OR = 0.87; 95%CI = 0.69-1.08; I 2 = 91.1%), with diabetes (P = 0.015), body mass index (BMI; P = 0.010), and possibly age (P = 0.061) as heterogeneity sources. Of note, in four studies (6197 HBV patients), HBV-infected individuals had a reduced NAFLD risk (OR = 0.68, 95%CI = 0.51-0.89, P = 0.006). A positive link between hyperlipidemia and metabolic syndrome emerged in hepatitis B patients, along with specific biochemical indicators, including BMI, creatinine, uric acid, fasting blood glucose, and homeostasis model assessment of insulin resistance. CONCLUSION: HBV infection may provide protection against HS; however, the occurrence of HS in patients with HBV infection is associated with metabolic syndrome and specific biochemical parameters.

ABSTRACT

Rifampicin, essential for long-term tuberculosis treatment, requires rigorous control of non-therapeutic impurities due to their potential adverse, including mutagenic effects. Reports on control strategies for genotoxic impurities in rifampicin have been limited. This study introduced an analytical method to identify potential genotoxic impurities from the synthesis of raw materials. The structure of the 25-deacetyl-23-acetyl-rifampicin genotoxic impurity was confirmed using nuclear magnetic resonance, high-resolution mass spectrometry (HRMS), and high-performance liquid chromatography (HPLC). An HPLC-HRMS method was established and validated for detecting another genotoxic impurity, 1-amino-4-methylpiperazine, adhering to the International Council on Harmonization guidelines, which include specificity, linearity, detection and quantification limits, accuracy, precision, and robustness. These developments improve the quality control strategy for genotoxic impurities in rifampicin, ensuring product safety.

ABSTRACT

The eyes are one of the most important sensory organs in the human body. Currently, diseases such as limbal stem cell deficiency, cataract, retinitis pigmentosa and dry eye seriously threaten the quality of people's lives, and the treatment of advanced blinding eye disease and dry eye is ineffective and costly. Thus, new treatment modalities are urgently needed to improve patients' symptoms and suffering. In recent years, stem cell-derived three-dimensional structural organoids have been shown to mimic specific structures and functions similar to those of organs in the human body. Currently, 3D culture systems are used to construct organoids for different ocular growth and development models and ocular disease models to explore their physiological and pathological mechanisms. Eye organoids can also be used as a platform for drug screening. This paper reviews the latest research progress in regard to eye organoids (the cornea, lens, retina, lacrimal gland, and conjunctiva).

ABSTRACT

BACKGROUND: This study aimed to investigate the feasibility and efficacy of near-infrared fluorescence-guided laparoscopic anatomical hepatectomy (LAH) using a novel indocyanine green (ICG)-human serum albumin complex (HSA) in patients with hepatocellular carcinoma. METHODS: Clinical data of hepatocellular carcinoma patients who underwent ICG-HSA fluorescence-guided LAH at our center from January 2024 to April 2024 were prospectively collected and analyzed. Ultraviolet absorption spectroscopy was used to test the absorption and stability of ICG-HSA complex solutions under different conditions. After determining the optimal ratio, the complex was administered intravenously during surgery to perform negative staining via Glissonean pedicle isolation. LAH was performed along the fluorescence-demarcated boundaries. RESULTS: Thirty-one patients were included (24 men; mean age, 54.61 ± 13.54 years). The median maximum tumor diameter was 2.80 (interquartile range [IQR], 2.00-4.00) cm. S8 segmentectomy (22.6%) and right posterior segmentectomy (19.4%) were the most common resections performed. Successful fluorescence negative staining was achieved in all patients using ICG and HSA at a 1:6 molar ratio at room temperature. Mean operation time was 297.58 ± 85.53 min, Median intraoperative blood loss was 100.0 mL (IQR, 50.0-200.0). The median surgical margin distance was 0.90 cm (IQR, 0.40-1.50). The postoperative complication rate was 45.2% (35.5% Clavien-Dindo grade I and 9.7% grade II). The median length of hospital stay was 5.0 days (IQR, 4.0-5.0). CONCLUSION: ICG-HSA-assisted LAH is safe and feasible. Compared with free ICG, the novel ICG-HSA complex exhibits better optical properties and in vivo stability, which can improve the accuracy of intraoperative liver segment localization and optimize the anatomical dissection plane. It has the potential to become an ideal fluorescent imaging agent for anatomical hepatectomy.

ABSTRACT

Amomum villosum Lour. (A. villosum) is the original plant of the medicinal and culinary spice Amomi Fructus (Sharen) and is an important economic crop in the Lingnan region of China. During the cultivation and production of A. villosum, prolonged reliance on single asexual reproduction has exacerbated the degradation of its varieties, leading to inconsistent yields and quality. Building upon earlier cultivar selection efforts, this study provides a comprehensive evaluation of two newly bred A. villosum varieties (A11 and A12) from perspectives including plant traits, product characteristics, active ingredients, and multi-omics analysis. It was found that A12 plants display enhanced robustness, more aromatic fruits, higher yields, and elevated levels of bornyl acetate, A11 shows the advantage of a high camphor content, and the different metabolites and differentially expressed genes of the two varieties were significantly enriched in multiple metabolic pathways. Additionally, A12 contained more terpenoids and substances with aromatic odors such as sweet, fruity, floral, and green. Furthermore, a key gene (Wv_032842) regulating the acetylation of bornyl was discovered, and its significantly higher expression, in A12. In conclusion, this study has a guiding significance for the evaluation of germplasm resources and the breeding of excellent varieties of A. villosum.

ABSTRACT

Euphorbia dentata Michx. is an invasive plant species in China, known for its toxicity and potential to reduce crop yields, posing numerous threats. To gain a deeper understanding of this invasive plant, phytochemical methods were employed to isolate 13 terpenoids (1-11, 19, 20) and 7 sterols (12-18) from the ethanol extract of E. dentata, identifying one new compound and 19 known compounds. Within spectroscopic methods such as NMR, HR-ESI-MS, and ECD, the structures and absolute configurations of these compounds were established. Among them, dentatacid A (11) possesses an unprecedented 2, 3-seco-arbor-2, 3-dioic skeleton within the potential biosynthetic pathway proposed. Dentatacid A also exhibited excellent anti-proliferative activity against the HT-29 (human colorectal adenocarcinoma) cell line, with an IC50 value of 2.64 ± 0.78 µM, which was further confirmed through network pharmacology and molecular docking. This study significantly expands the chemical diversity of E. dentata and offers new insights into the resource utilization and management of this invasive plant from the perspective of natural product discovery.

ABSTRACT

TiAl alloys possess excellent properties, such as low density, high specific strength, high elastic modulus, and high-temperature creep resistance, which allows their use to replace Ni-based superalloys in some high-temperature applications. In this work, the traditional TiAl alloy Ti-48Al-2Nb-2Cr (Ti4822) was alloyed with additional Nb and fabricated using laser metal deposition (LMD), and the impacts of this additional Nb on the microstructure and mechanical and tribological properties of the as-fabricated alloys were investigated. The resulting alloys mainly consisted of the γ phase, trace ß0 and α2 phases. Nb was well distributed throughout the alloys, while Cr segregation resulted in the residual ß0 phase. Increasing the amount of Nb content increased the amount of the γ phase and reduced the amount of the ß0 phase. The alloy Ti4822-2Nb exhibited a room-temperature (RT) fracture strength under a tensile of 568 ± 7.8 MPa, which was nearly 100 MPa higher than that of the Ti4822-1Nb alloy. A further increase in Nb to an additional 4 at.% Nb had little effect on the fracture strength. Both the friction coefficient and the wear rate increased with the increasing Nb content. The wear mechanisms for all samples were abrasive wear with local plastic deformation and oxidative wear, resulting in the formation of metal oxide particles.

ABSTRACT

OBJECTIVE: Previous studies have suggested that irritable bowel syndrome (IBS) is strongly associated with psychiatric disorders. However, it is unclear whether this association is causal, concomitant, or accidental. Thus, we performed Mendelian randomization (MR) analysis to evaluate the causal effects of several psychiatric disorders on IBS. METHODS: Summary data of genome-wide association studies (GWASs) were obtained mainly from the Psychiatric Genomics Consortium (PGC) on individuals of European ancestry and from a recent GWAS on IBS. We used three MR methods, the inverse-variance weighting (IVW), weighted median (WM), and MR-Egger regression (MR-Egger). In addition, two other indicators, namely, the MR-IVW Cochran's Q statistic and MR-Egger intercept, were used to assess heterogeneity and detect directional horizontal pleiotropy, respectively. RESULTS: Heritability was high for bipolar disorder (81.18 %, 95 % CI = 73.18-148.18 %), schizophrenia (33.88 %, 95 % CI = 33.57-38.19 %), and panic disorder (30.66 %, 95 % CI = 20.74-40.58 %). For other disorders, there was a low liability-scale SNP heritability for major depressive disorder (MDD) (0.67 %, 95 % CI = 0.61-0.73 %), anxiety disorder (7.63 %, 95 % CI = 1.67-13.59 %), PTSD (0.96 %, 95 % CI = 0.12-1.8 %), and IBS (2.44 %, 95 % CI = 2.13-2.75 %). We also observed that schizophrenia had a significant causal effect on IBS according to MR-IVW. Notably, the individual causal estimates of genetic instruments for MDD and schizophrenia were heterogeneous, but no pleiotropic effects were observed. CONCLUSIONS: Our analyses revealed the causal effects of MDD and schizophrenia on IBS, a matter that has been subject to debate for decades, and also showed that IBS had causal effects on MDD.

ABSTRACT

We report on the efficient generation of intense terahertz radiation from the organic crystal N-benzyl-2-methyl-4-nitroaniline pumped by chirped Ti:sapphire femtosecond laser pulses. The THz energy and spectrum as a function of the pump fluence and duration of the chirped laser pulses are studied systematically. For the appropriate positively chirped pump pulses, a significant boost in the THz generation efficiency by a factor of around 2.5 is achieved, and the enhancement of high-frequency components (>1 THz) shortens the THz pulse duration. Via complete characterization of THz properties and transmitted laser spectra, this nonlinear behavior is attributed to the extended effective interaction length for phase matching as a result of the self-phase modulation of the intense pump laser pulses. Numerical calculations well reproduce the experimental observation. Our results demonstrate a robust, efficient, strong-field (up to several MV/cm) THz source using the common sub-10 mJ and sub-100 fs Ti:sapphire laser systems without optical parametric amplifiers.

ABSTRACT

Apoptotic proteins play a crucial role in the apoptosis process, ensuring a balance between cell proliferation and death. Thus, further elucidating the regulatory mechanisms of apoptosis will enhance our understanding of their functions. However, the development of computational methods to accurately identify positive and negative regulation of apoptosis remains a significant challenge. This work proposes a machine learning model based on multi-feature fusion to effectively identify the roles of positive and negative regulation of apoptosis. Initially, we constructed a reliable benchmark dataset containing 200 positive regulation of apoptosis and 241 negative regulation of apoptosis proteins. Subsequently, we developed a classifier that combines the support vector machine (SVM) with pseudo composition of k-spaced amino acid pairs (PseCKSAAP), composition transition distribution (CTD), dipeptide deviation from expected mean (DDE), and PSSM-composition to identify these proteins. Analysis of variance (ANOVA) was employed to select optimized features that could yield the maximum prediction performance. Evaluating the proposed model on independent data revealed and achieved an accuracy of 0.781 with an AUROC of 0.837, demonstrating our model's potent capabilities.

ABSTRACT

BACKGROUND: This study evaluates functional larynx preservation in patients with hypopharyngeal cancer (HPC) and laryngeal cancer (LC) who achieved complete remission following radiotherapy (RT) or concurrent chemoradiation (CCRT). METHODS: HPC and LC patients treated with RT/CCRT from 1999 to 2017 were retrospectively analyzed. Severe late dysphagia and tracheostomy cases were assessed to determine laryngeal function. Long-term preservation rate of functional larynx and associated factors were evaluated. RESULTS: Of 152 patients (55 HPC, 97 LC), nine developed severe dysphagia, occurring on average 58.2 months post-treatment. HPC and cervical node metastasis significantly increased the risk of laryngeal function impairment (p < 0.001 and p = 0.014, respectively), presenting a continued decline in functional larynx preservation rate beyond 10 years. CONCLUSIONS: Patients with HPC and cervical node metastasis demonstrate an increased risk for long-term laryngeal function impairment despite successful oncologic outcomes. This risk extends beyond 10 years, underscoring the need for prolonged monitoring and comprehensive support.

ABSTRACT

Although the Omicron variant has been associated with greater transmissibility and tropism of the upper respiratory tract, the clinical and pathogenic features of patients infected with the Omicron variant during an outbreak in China have been unclear. Adults with COVID-19 were retrospectively enrolled from seven medical centers in Guangzhou, China, and clinical information and specimens ( BALF, sputum, and throat swabs) from participants were collected. Conventional detection methods, metagenomics next-generation sequencing (mNGS), and other methods were used to detect pathogens in lower respiratory tract samples. From December 2022 to January 2023, we enrolled 836 patients with COVID-19, among which 56.7% patients had severe/critical illness. About 91.4% of patients were infected with the Omicron strain (BA.5.2). The detection rate of possible co-infection pathogens was 53.4% by mNGS, including Klebsiella pneumoniae (16.3%), Aspergillus fumigatus (12.2%), and Pseudomonas aeruginosa (11.8%). The co-infection rate was 19.5%, with common pathogens being Streptococcus pneumoniae (11.5%), Haemophilus influenzae (9.2%), and Adenovirus (6.9%). The superinfection rate was 75.4%, with common pathogens such as Klebsiella pneumoniae (26.1%) and Pseudomonas aeruginosa (19.4%). Klebsiella pneumoniae (27.1%% vs 6.1%, P < 0.001), Aspergillus fumigatus (19.6% vs 5.3%, P = 0.001), Acinetobacter baumannii (18.7% vs 4.4%, P = 0.001), Pseudomonas aeruginosa (16.8% vs 7.0%, P = 0.024), Staphylococcus aureus (14.0% vs 5.3%, P = 0.027), and Streptococcus pneumoniae (0.9% vs 10.5%, P = 0.002) were more common in severe cases. Co-infection and superinfection of bacteria and fungi are common in patients with severe pneumonia associated with Omicron variant infection. Sequencing methods may aid in the diagnosis and differential diagnosis of pathogens. IMPORTANCE: Our study has analyzed the clinical characteristics and pathogen spectrum of the lower respiratory tract associated with co-infection or superinfection in Guangzhou during the outbreak of the Omicron strain, particularly after the relaxation of the epidemic prevention and control strategy in China. This study will likely prompt further research into the specific issue, which will benefit clinical practice.

ABSTRACT

Immunotherapy has revolutionized the cancer treatment paradigm, yet efficient immunotherapeutic responses against immune-cold/desert cancers remain challenging. Herein, we report that photoactivatable nanoagonists yield a potent antitumor synergy of photoimmunotherapy against pancreatic ductal adenocarcinoma (PDAC). The nanoagonist was fabricated by assembling an amphiphilic boron dipyrromethene-derived polymer conjugated with a Toll-like receptor agonist via a photocleavable linker and stimulator of interferon genes agonist. The nanoagonist enables light-induced generation of reactive oxygen species and on-demand release of the agonists to yield synergistic photoimmunotherapy. The produced tumor antigens promote dendritic cell maturation, which is further amplified by these agonists for eliciting adaptive immunity, accompanied by apparently abscopal and long-term memory effects. The nanoagonist further alleviates the fibrosis of tumor stroma and the immunosuppressive microenvironment, leading to the deep infiltrations of clinically used therapeutics and immune cells to yield preferable combinational treatments against PDAC models. These results provide valuable insights into activatable nanoparticles for cancer therapy against immune-desert cancers.

ABSTRACT

Background: Genicular nerve radiofrequency ablation (GNRFA) is a popular and effective procedure to treat arthritic knee pain. For refractory arthritic pain that fails conservative treatment, total knee arthroplasty (TKA) has been an excellent option. Unfortunately, 15-30% of people who undergo a TKA continue to experience pain and stiffness in the knee. The treatment options for post-TKA knee pain are limited. Pain providers have been trialing GNRFA on this pain condition. However, convincing evidence of its efficacy in treating post-TKA pain is still lacking. Methods: This is a retrospective study of 73 patients who had undergone genicular nerve RFA, 46 (63.01%) with osteoarthritic pain, and 27 (36.99%) with post-TKA pain. We compared the outcomes (pain relief, function, and complications) between these two groups at 3 months and 6 months after RFA. Results: Before RFA, there was no significant difference in initial pain and functional level between these two groups. After RFA, the two groups had comparable pain relief at 3 months (p = 0.68) and 6 months (p = 0.53), and similar functionality at 3 months (p = 0.36) and 6 months (p = 0.65).The overall success rate (≥50% pain relief after RFA) was 80.82%, 95% CI: 70.34%-88.22% (osteoarthritic group 80.43%, 95% CI: 66.83%-89.35%, post-TKA 81.48%, 95% CI: 63.30%-91.82%, P = 0.91) at 3-month follow-up and 56.16%, 95% CI: 44.76%-66.95% (osteoarthritic group 56.52%, 95% CI: 42.25%-69.79%, post-TKA 55.56%, 95% CI: 37.31%-72.41%, P = 0.94) at 6-month follow-up.There were no reported complications in either group. Conclusions: Genicular Nerve Radiofrequency Ablation (GNRFA) holds the potential to be equally effective for both post-TKA knee pain and osteoarthritic knee pain.
