Objective To study the effect of comfort nursing management of postoperative pediatric upper extremity fractures on the basis of the standard operating procedure (SOP) management model. Methods The clinical data of 150 pediatric upper extremity fracture patients treated postoperatively at our hospital (August 2023–August 2024) were retrospectively analyzed. Participants were divided into a control group (conventional care) and an intervention group (SOP-based comfort care) according to nursing management methods. Postoperative functional exercise outcomes were compared. Results A total of 150 children were enrolled (75 per group). Baseline assessments confirmed no significant differences in joint mobility, joint function, pain, comfort, or psychological resilience scores between groups (all P  > 0.05). Post-intervention analyses demonstrated significantly greater joint mobility in the intervention group ( P  < 0.001), higher joint function scores ( P  < 0.001), lower pain scores ( P  < 0.001), improved comfort scores across all dimensions ( P  < 0.001), and enhanced psychological resilience ( P  < 0.001), with significantly better functional exercise adherence observed clinically in the intervention group. Conclusion The implementation of SOP-based management model comfort care for pediatric children with upper extremity fractures can improve their postoperative functional exercise cooperation, pain status relief after surgical treatment, emotional stability, and degree of cooperation in the clinical implementation of functional exercise.

Bivalve molluscs are descendants of an early-Cambrian lineage superbly adapted to benthic filter feeding. Adaptations in form and behavior are well recognized, but the underlying molecular mechanisms are largely unknown. Here, we investigate the genome, various transcriptomes, and proteomes of the scallop Chlamys farreri , a semi-sessile bivalve with well-developed adductor muscle, sophisticated eyes, and remarkable neurotoxin resistance. The scallop’s large striated muscle is energy-dynamic but not fully differentiated from smooth muscle. Its eyes are supported by highly diverse, intronless opsins expanded by retroposition for broadened spectral sensitivity. Rapid byssal secretion is enabled by a specialized foot and multiple proteins including expanded tyrosinases. The scallop uses hepatopancreas to accumulate neurotoxins and kidney to transform to high-toxicity forms through expanded sulfotransferases, probably as deterrence against predation, while it achieves neurotoxin resistance through point mutations in sodium channels. These findings suggest that expansion and mutation of those genes may have profound effects on scallop’s phenotype and adaptation. Bivalve molluscs have evolved various characteristics to adapt to benthic filter-feeding. Here, Li et al investigate the genome, transcriptomes and proteomes of scallop Chlamys farreri , revealing evidences of molecular adaptations to semi-sessile life and neurotoxins.

Camellia yuhsienensis was used to cross with Camellia oleifera to improve the resistance of oil camellia anthracnose. However, unilateral cross-incompatibility (UCI) between C. oleifera and C. yuhsienensis was found during the breeding process. Five C.oleifera cultivars and four C. uhsienensis materials were tested to confirm the UCI between C. oleifera and C. yuhsienensis . ‘Huashuo’ (HS) and ‘Youza 2’ (YZ2) were used to represent these two species to characterize the UCI, including pollen tube growth, fertilization and fruit development. The results demonstrated that UCI was prevalent between C. oleifera and C. yuhsienensis . The asynchronous flowering period was a pre-pollination barrier that limited mating between these two species under natural conditions. Interspecific pollen tubes were observed through the styles of these two plants, though the growth rates differed considerably. At 96 hours after pollination, the pollen tube of YZ2 barely entered the ovule, but remained at the base of the style and became swollen. However, the HS pollen tube entered the ovule 48 hours after pollination, double fertilization was observed, and the fruit and seeds developed commonly. Relative to compatible combinations, most unfertilized ovules in incompatible combinations failed to grow, turned brown 150 days after pollination, and the fruits were smaller than expected with uneven enlargement. Investigations on both semi- in vivo and in vitro pollen tubes gave us new idea for thought: the HS style has a stronger inhibitory effect on the interspecific pollen tubes, while calcium alleviates the inhibitory of styles but failed to prevent the appearance of abnormal pollen tube morphology. This study provides useful information on interspecific hybridization between C. oleifera and C. yuhsienensis for understanding reproductive isolation mechanisms and breeding programs in genus Camellia .

Background A single measurement of the triglyceride-glucose (TyG) index, a simple and reliable surrogate marker of insulin resistance, is associated with ischemic stroke. However, evidence for an effect of a long-term elevation in TyG index on ischemic stroke is limited. Therefore, we evaluated the relationship between cumulative TyG index exposure and the risk of ischemic stroke. Methods A total of 54,098 participants in the Kailuan study who had not experienced ischemic stroke underwent three measurements of fasting blood glucose and triglycerides during 2006–2007, 2008–2009, and 2010–2011. Cumulative exposure to TyG index was calculated as the weighted sum of the mean TyG index value for each time interval (value × time). Participants were placed into four groups according to the quartile of the weighted mean: Q1 group, < 32.01; Q2 group, 32.01–34.45; Q3 group, 34.45–37.47; and Q4 group, ≥ 37.47. Cox proportional hazard models were used to assess the relationships of the cumulative TyG index with incident ischemic stroke by calculating hazard ratios (HRs) and 95% confidence intervals (95% CIs). Results There were 2083 incident ischemic stroke events over the 9 years of follow-up. The risk of ischemic stroke increased with the quartile of cumulative TyG index. After adjustment for multiple potential confounders, participants in groups Q4, Q3, and Q2 had significantly higher risks of ischemic stroke, with HRs (95% CIs) of 1.30 (1.12–1.52), 1.26 (1.09–1.45), and 1.09 (0.94–1.27), respectively ( P trend  < 0.05), compared with the Q1 group. The longer duration of high TyG index exposure was significantly associated with increased ischemic stroke. Conclusions High cumulative TyG index is associated with a higher risk of ischemic stroke. This finding implies that monitoring and the maintenance of an appropriate TyG index may be useful for the prevention of ischemic stroke.

Neuronal intranuclear inclusion disease (NIID) is a rare autosomal-dominant, progressive neurodegenerative condition characterized by complex and variable clinical manifestations that can affect multiple neurological domains. This report describes the case of a 49-year-old female patient with a 10-year history of headaches, whose older sister had been diagnosed with NIID 1 year earlier through genetic testing and a skin biopsy. Recently, the patient developed dizziness and vomiting. Although symptomatic treatment reduced incidents of vomiting, her dizziness progressively worsened. It was accompanied by lower limb weakness, gait instability, hallucinations, and abnormal sleep behaviors. Routine imaging and cerebrospinal fluid immunological and microbiological tests revealed no abnormalities. Genetic analysis revealed a 130-repeat expansion in the NOTCH2NLC gene, and skin biopsy confirmed the presence of intranuclear inclusions, establishing the NIID diagnosis. However, during hospitalization, the patient’s bilateral lower limb tremors, hallucinations, and abnormal sleep behaviors suggested a possible acute encephalitic process. Subsequent serum testing detected positive anti-contactin-associated protein-like 2 (CASPR2) antibodies. Significant symptom improvement following treatment with immunoglobulins and steroids supported the diagnosis of coexisting acute anti-CASPR2 antibody encephalitis and NIID. This is the first reported case of dual disease coexistence.

Background: The marine Gram-negative bacterium Vibrio anguillarum is one of the major pathogens in aquaculture. Iron uptake is a prerequisite for virulence and is strictly controlled by a global iron uptake regulator, Fur, which acts as a repressor under iron-replete conditions. When iron is depleted, Fur also functions as an activator, playing an important role in pathogenesis. It is unclear whether this upregulation model is mediated by a small RNA, RyhB.Methods: The small RNA, VaryhB, was deleted in V. anguillarum strain 775, and its regulon was investigated using transcriptomic analysis. The roles of VaRyhB in siderophore synthesis, chemotaxis and motility, and oxidative stress were evaluated using chrome azurol S (CAS) liquid assay, swimming motility assay, and intracellular reactive oxygen species (ROS) assay, respectively. The virulence of VaRyhB was evaluated by challenging turbot larvae intraperitoneally.Results: The small RNA called VaRyhB identified in V. anguillarum strain 775 is significantly longer than that in Escherichia coli. Transcriptomic analysis revealed that VaRyhB is critical for iron homeostasis under limited iron conditions, and deletion of VaRyhB resulted in lower expression levels of certain genes for siderophore biosynthesis and transport, thereby leading to impaired growth, reduced siderophore production, and decreased pathogenesis. The virulence factor motility is also upregulated by VaRyhB, and reduced motility capability was observed in the ΔVaryhB mutant, which may be another reason resulting in weak pathogenesis. The sensitivity toward H2O2 in the ΔVafur mutant could be restored by the loss of VaRyhB, suggesting that the role of Fur in oxidative stress is mediated by VaRyhB. VaRyhB also functions to inhibit the expression of genes involved in Fe-S assembly and the TCA cycle. In addition, two aspects of the type VI secretion system and molybdenum cofactor biosynthesis were first identified as being regulated by VaRyhB.Conclusion: In V. anguillarum, the sRNA VaRyhB plays a critical role in the inhibition of genes involved in the TCA cycle, Fe-S assembly, and the type VI secretion system. It is also essential for the activation of siderophore synthesis, chemotaxis and motility, and anaerobic denitrification. Our work provides the first evidence of the VaRyhB regulon and its role in the pathogenesis of V. anguillarum.

Model robustness is an important index in medical cybersecurity, and hard-negative samples in electronic medical records can provide more gradient information, which can effectively improve the robustness of a model. However, hard negatives pose difficulties in terms of their definition and acquisition. To solve these problems, a data augmentation approach consisting of fusing SimBERT and a knowledge graph for application to a hard-negative sample is proposed in this paper. Firstly, we selected 40 misdiagnosed cases of diabetic complications as the original data for data augmentation. Secondly, we divided the contents of the electronic medical records into two parts. One part consisted of the core disease phrases in the misdiagnosed case records, which a medical specialist selected. These denoted the critical diseases that the model diagnosed as negative samples. Based on these core symptom words, new symptom phrases were directly generated using the SimBERT model. On the other hand, the noncore phrases of misdiagnosed medical records were highly similar to the positive samples. We determined the cosine similarity between the embedding vector of the knowledge graph entities and a vector made up of the noncore phrases. Then, we used Top-K sampling to generate text. Finally, combining the generated text from the two parts and the disturbed numerical indexes resulted in 160 enhancement samples. Our experiment shows that the distances between the samples generated using the SimKG-BERT model’s samples were closer to those of the positive samples and the anchor points in the space vector were closer than those created using the other models. This finding is more in line with how hard negatives are defined. In addition, compared with the model without data augmentation, the F1 values in the three data sets of diabetic complications increased by 6.4%, 2.24%, and 5.54%, respectively. The SimKG-BERT model achieves data augmentation in the absence of misdiagnosed medical records, providing more gradient information to the model, which not only improves the robustness of the model but also meets the realistic needs of assisted-diagnosis safety.

Many single-land-use simulation models are available to simulate and predict Land Use and Land Cover Change (LUCC). However, few studies have used multiple models to simulate LUCC in the same region. The paper utilizes the CA-Markov model, Land Change Modeler (LCM), and Patch-generating Land Use Simulation model (PLUS) with natural and social driving factors to simulate the LUCC on the Western Sichuan Plateau, using Kappa coefficient, overall accuracy (OA), and Figure of Merit (FoM) to verify the accuracy of the model, and selects a suitable model to predict the LUCC and landscape pattern in the study area from 2020 to 2070. The results are as follows: (1) The LCM has the highest simulation effect, and its Kappa coefficient, OA, and FoM are higher than the other two models. (2) The area of land types other than grassland and wetland will increase from 2020 to 2070. Among them, the grassland area will decrease, but is still most prominent land category in this region. The proportion of wetland areas remains unchanged. The fragmentation degree of forest (F), grassland (GL), shrubland (SL), water bodies (WBs), bare areas (BAs), and permanent ice and snow (PIS) decreases, and the distribution shows a trend of aggregation. The dominance of F and C decreases but still dominates in the landscape. The overall landscape aggregation increased and complexity decreased, and each landscape type’s diversity, evenness, and richness increased, presenting as a more reasonable development. Using multiple models to simulate the LUCC in the same region, and choosing the most suitable local land model is of great significance to scientifically manage and effectively allocate the land resources in the field.

The seed of Herpetospermum pedunculosum (Ser.) C.B. Clarke, known in Chinese as Bo-Leng-Gua-Zi and in Tibetan as Sejimedo, are here abbreviated as H. pedunculosum seeds. Herpetospermum pedunculosum seeds is a traditional Chinese medicine for protecting the liver, clearing heat, and detoxifying. A total of 125 chemical metabolites of H. pedunculosum seeds are found, including lignans, fatty acids, terpenes, coumarins, and others. The pharmacological activities of H. pedunculosum seeds are mainly in hepatoprotective, antioxidant, anti-cancer cells, and anticholestatic effects. In clinical application, it is mainly used in combination with other traditional Chinese medicines to play a key role in treating the liver disease. This paper gives a systematic review of above research aspects, proposes the potential limitations and put forward plausible solutions. Relevant literatures were searched in PubMed, Web of Science and Chinese National Knowledge Infrastructure with Herpetospermum as the key word. A number of studies have shown that H. pedunculosum seeds exert excellent hepatoprotective effects by acting on NF-κB, TGF-β, and Keap1-Nrf2 signaling pathways, which provide a solid base for its clinic application. However, more research is needed to explore the standard cultivation and quality evaluation of H. pedunculosum seeds and systematical structure-activity relationship of its active metabolites.
