Myopia has become a significant eye health problem, which is thought to result from the complex interactions of genetic and environmental factors. This review focuses on two types of hereditary retinal diseases caused by mutations in photoreceptor genes, including rod-cone cell dystrophy(retinitis pigmentosa)and cone dysfunction syndromes(achromatopsia, blue cone monochromatism and Bornholm eye disease). It systematically explores the intrinsic connection between these diseases and the myopia phenotype, and elaborates on the core mechanisms by which pathogenic genes such as RPGR and OPN1LW/OPN1MW, which cause defects in ciliary structure and protein transport and interfere with the visual signal pathway, jointly induce choroidal thinning and scleral remodeling, ultimately driving the elongation of axial length and the occurrence of myopia. By tracing the association of photoreceptor gene mutations with myopia, this article provides a new perspective for in-depth understanding of the genetic mechanism of myopia and is of great significance for the development of early risk warning and targeted intervention strategies.

Regenerating periodontal bone defect surrounding periodontal tissue is crucial for orthodontic or dental implant treatment. The declined osteogenic ability of periodontal ligament stem cells (PDLSCs) induced by inflammation stimulus contributes to reduced capacity to regenerate periodontal bone, which brings about a huge challenge for treating periodontitis. Here, inspired by the adhesive property of mussels, we have created adhesive and mineralized hydrogel microspheres loaded with traditional compound cordycepin (MMS-CY). MMS-CY could adhere to the surface of alveolar bone, then promote the migration capacity of PDLSCs and thus recruit them to inflammatory periodontal tissues. Furthermore, MMS-CY rescued the impaired osteogenesis and ligament-forming capacity of PDLSCs, which were suppressed by the inflammation stimulus. Moreover, MMS-CY also displayed the excellent inhibitory effect on the osteoclastic activity. Mechanistically, MMS-CY inhibited the premature senescence induced by the inflammation stimulus through the nuclear factor erythroid 2-related factor (NRF2) pathway and reducing the DNA injury. Utilizing in vivo rat periodontitis model, MMS-CY was demonstrated to enhance the periodontal bone regeneration by improving osteogenesis and inhibiting the osteoclastic activity. Altogether, our study indicated that the multi-pronged approach is promising to promote the periodontal bone regeneration in periodontitis condition by reducing the inflammation-induced stem cell senescence and maintaining bone homeostasis.

The cellular and molecular components of the tumor immune microenvironment (TIME) and their information exchange processes significantly influence the trends of anti-tumor immunity. In recent years, numerous studies have begun to evaluate TIME in the context of previous cancer treatment strategies. This review will systematically summarize the compositional characteristics of TIME and, based on this foundation, explore the impact of current cancer therapies on the remodeling of TIME, aiming to provide new insights for the development of innovative immune combination therapies that can convert TIME into an anti-tumor profile.

Triple-negative breast cancer (TNBC) represents an aggressive breast cancer subtype with poor prognosis and limited targeted treatment options. This investigation examined the anti-cancer potential of Caerulomycin A (Cae A), a natural compound derived from marine actinomycetes, against TNBC. Cae A demonstrated selective inhibition of viability and proliferation in TNBC cell lines, including 4T1, MDA-MB-231, and MDA-MB-468, through apoptosis induction. Mechanistic analyses revealed that the compound induced sustained endoplasmic reticulum (ER) stress and subsequent upregulation of C/EBP homologous protein (CHOP) expression, resulting in mitochondrial damage-mediated apoptosis. Inhibition of ER stress or CHOP expression knockdown reversed mitochondrial damage and apoptosis, highlighting the essential role of ER stress and CHOP in Cae A's anti-tumor mechanism. Both oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) decreased in TNBC cells following Cae A treatment, indicating reduced mitochondrial respiratory and glycolytic capacities. This diminished energy metabolism potentially triggers ER stress and subsequent apoptosis. Furthermore, Cae A exhibited significant anti-tumor effects in the 4T1 tumor model in vivo without apparent toxicity. The compound also effectively inhibited human TNBC organoid growth. These results indicate that Cae A may serve as a potential therapeutic agent for TNBC, with its efficacy likely mediated through the disruption of glucose metabolism and the induction of ER stress-associated apoptosis.

Petroleum hydrocarbon pollution has become one of the global environmental problems, posing a serious threat to the environment and human health. Microbial remediation plays an important role in the remediation of petroleum hydrocarbon-contaminated environment. Nevertheless, the stress factors present in the environment polluted by petroleum hydrocarbons limit the effectiveness of microbial remediation. This paper reviews the common stress factors in petroleum hydrocarbon-polluted environment and the response mechanisms of microorganisms to these factors. Furthermore, we introduce the methods to improve microbial tolerance, such as irrational modification, rational modification based on systems biology tools or tolerance mechanisms, and the construction of microbial consortia. The application of these methods is expected to improve the viability and remediation efficiency of microorganisms in petroleum hydrocarbon-contaminated environment and provide new perspectives and technical support for environmental remediation.

The plant F-box protein more axillary growth 2 (MAX2) is a key factor in the signal transduction of strigolactones (SLs) and karrinkins (KARs). As the main component of the SKP1-CUL1-FBX (SCF) complex ubiquitin ligase E3, MAX2 is responsible for specifically recognizing the target proteins, suppressor of MAX2 1/SMAX1-like proteins (SMAX1/SMXLs), which would be degraded after ubiquitination. It can thereby regulate plant morphogenesis and stress responses. There exist homologous genes of MAX2 in the important grain and oil crop soybean (Glycine max). However, its role in plant defense responses has not been investigated yet. Here, GmMAX2b, a homologous gene of MAX2, was successfully cloned from stressed soybean. Bioinformatics analysis revealed that there were two MAX2 homologous genes, GmMAX2a and GmMAX2b, with a similarity of 96.2% in soybean. Their F-box regions were highly conserved. The sequence alignment and cluster analysis of plant MAX2 homologous proteins basically reflected the evolutionary relationship of plants and also suggested that soybean MAX2 might be a multifunctional protein. Expression analysis showed that plant pathogen infection and salicylic acid treatment induced the expression of GmMAX2b in soybean, which is consistent with that of MAX2 in Arabidopsis. Ectopic expression of GmMAX2b compensated for the susceptibility of Arabidopsis max2-2 mutant to pathogen, indicating that GmMAX2b positively regulated plant disease resistance. In addition, yeast two hybrid technology was used to explore the potential target proteins of GmMAX2b. The results showed that GmMAX2b interacted with SMXL6 and weakly interacted with SMXL2. In summary, GmMAX2b is a positive regulator in plant defense responses, and its expression is induced by pathogen infection and salicylic acid treatment. GmMAX2b might exert its effect through interaction with SMXL6 and SMXL2. This study expands the theoretical exploration of soybean disease resistant F-box and provides a scientific basis for future soybean disease resistant breeding.

The 2022 WHO classification of endocrine and neuroendocrine tumors (5th edition) categorizes thyroid follicular cell-derived tumors into benign, low-risk, and malignant types. Benign tumors now include thyroid follicular nodular lesions. A newly added category previously termed "borderline tumors" have been revised to low-risk follicular cell-derived tumors, which encompass non-invasive follicular thyroid neoplasm with papillary-like nuclear features, thyroid tumors of uncertain malignant potential, and hyalinizing trabecular tumors. The new WHO classification stratifies malignant follicular cell-derived tumors based on molecular characteristics and invasiveness: papillary thyroid carcinoma (PTC) with various histological subtypes represents BRAF-like malignancies; invasive encapsulated follicular variant PTC and follicular thyroid carcinoma represent RAS-like malignancies. Oncocytic carcinoma is now recognized as a distinct entity, specifically referring to tumors composed of ≥75% oncocytic follicular cells lacking PTC nuclear features and high-grade characteristics (necrosis and mitotic figures ≥3/2 mm²). A new category termed "high-grade follicular cell-derived thyroid carcinoma" has been added, encompassing traditional poorly differentiated thyroid carcinoma and differentiated high-grade thyroid carcinoma. Anaplastic thyroid carcinoma(ATC) remains the most undifferentiated type, with thyroid squamous cell carcinoma now classified as a subtype of ATC. The term "papillary thyroid microcarcinoma" is no longer recommended as a distinct subtype. Cribriform-morular thyroid carcinoma is no longer classified as a subtype of PTC, but is instead categorized as a tumor of uncertain histogenesis.

Objective To investigate and analyze the occupational stress levels and influencing factors among radiation workers in China, and provide a reference for alleviating occupational stress and promoting mental health. Methods Using the general situation questionnaire, Effort-Reward Imbalance questionnaire, and radiation protection knowledge questionnaire, a convenience sampling method was adopted to investigate the occupational stress of 243 radiation workers in Liaoning, Fujian, Guangdong, and Xinjiang provinces. The independent samples t-test, one-way analysis of variance, chi-square test, and binary logistic regression were used to analyze the influencing factors. Results The average score of Effort-Reward Imbalance was 0.97 ± 0.22, and 100 (41.15%) radiation workers had occupational stress. There were significant differences in the detection rate of occupational stress among radiation workers of different ages, working years in radiation positions, monthly incomes, daily sleep durations, and daily working hours (P < 0.05). Logistic regression analysis identified daily working hours as a factor contributing to occupational stress. Conclusion The occupational stress among radiation workers in China is relatively severe. It is recommended to pay attention to the associated risks and implement targeted intervention measures to reduce the impact of occupational stress.

Fetal sacrococcygeal teratoma（SCT）is a rare condition，but the prognosis of fetuses diagnosed with SCT prenatally is generally poor，with a mortality rate of 13% to 50%. The primary causes of death include fetal hydrops and high?output heart failure，while other causes include tumor rupture，hemorrhage，preterm labor，dystocia，or malignant teratoma invasion of surrounding tissues. For large tumors，especially those with rich blood supply or rapid growth，intrauterine treatment should be considered to prevent arteriovenous shunting，reduce tumor size，and reverse fetal heart failure and hydrops. This approach aims to allow the fetus to grow safely to a viable gestational age，after which the tumor can be completely removed by secondary surgery following cesarean delivery or natural childbirth. Currently，there are five main intrauterine treatment strategies：①Ultrasound?guided cystic teratoma aspiration：single or multiple aspirations，intrauterine continuous drainage，or prenatal aspiration；②Ultrasound?guided alcohol sclerotherapy；③Open fetal surgery；④Laser ablation：fetoscopic?guided ablation of feeding vessels of the teratoma，or ultrasound?guided laser ablation；⑤ Ultrasound?guided radiofrequency ablation（RFA）.According to the literature，the latter two minimally invasive intrauterine treatment methods show better outcomes for teratomas containing solid components and are gradually becoming the mainstream treatment options.
