Objective:
To analyze the trends in incidence and mortality of prostate cancer in Ningbo City, Zhejiang Province, so as to provide insights into the prevention and control of prostate cancer.
Methods:
Data of the incidence and mortality of prostate cancer in Ningbo City from 2011 to 2023 were collected through Ningbo Chronic Disease Collaborative Management System. The incidence and mortality of prostate cancer were calculated and standardized by the data from the sixth national population census in 2010 and the Segi's world standard population in 1960. The trends in incidence and mortality of prostate cancer were evaluated using average annual percent change (AAPC).
Results:
A total of 15 411 cases of prostate cancer were reported in Ningbo City from 2011 to 2023, and the crude incidence, Chinese-standardized incidence and world-standardized incidence were 39.62/105, 22.18/105 and 16.49/105, respectively, showing upward trends (AAPC=14.782%, 10.390% and 10.608%, all P<0.05). The Chinese-standardized incidence of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (25.14/105 vs. 19.44/105; AAPC=9.057% and 14.272%, both P<0.05). The crude incidence of prostate cancer in the groups aged 50-<60 years, 60-<70 years, 70-<80 years and ≥80 years showed upward trends (AAPC=11.657%, 14.031%, 10.734% and 5.300%, all P<0.05). A total of 3 739 deaths were reported, and the crude mortality, Chinese-standardized mortality and world-standardized mortality were 9.66/105, 5.23/105 and 3.71/105, respectively, showing upward trends (AAPC=8.458%, 3.620% and 3.602%, all P<0.05). The Chinese-standardized mortality of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (5.35/105 vs. 5.13/105; AAPC=3.183% and 3.962%, both P<0.05). The crude mortality of prostate cancer the groups ageds ≥80 years showed an upward trend (AAPC=7.482%, P<0.05).
Conclusions
From 2011 to 2023, the incidence and mortality of prostate cancer in Ningbo City showed upward trends. Special attention should be paid to urban residents, and prostate cancer screening should be strengthened among males aged 50 years and older.

ObjectiveEarly blight is a common destructive disease in the growth process of Solanaceae crops, which can lead to crop failure and serious losses. Traditional crop disease detection methods are difficult to detect disease characteristics in a timely manner during the incubation period of disease, and thus take scientific and effective prevention and control measures. This study obtained hyperspectral images of early blight of peppers at different infection stages through continuous monitoring with a hyperspectral imager. The earliest identifiable time during the incubation period of early blight in peppers (the earliest identifiable time during the incubation period in this experiment was 24 h after inoculation) was determined using the spectral angle cosine-correlation coefficient and Chebyshev distance. MethodsTaking the symptoms of the latent period of early blight in peppers as the research object, 13 characteristic wavelengths were selected using a genetic algorithm. An identification model of crop disease latent period symptoms based on spectral features was established through optimized combinations of characteristic wavelengths combined with a logistic regression model. Simultaneously, a recognition model of the latent period of early blight in peppers based on image texture features was established using local binary patterns. ResultsThe experiment was tested with 120 samples. The accuracy of the identification model of crop disease latent period symptoms based on spectral features reached over 93% in both the training set and the test set. The accuracy of the identification model of crop disease latent period symptoms based on texture features reached 98.96% and 100% in the training set and test set, respectively. ConclusionBoth spectral features and texture features can be used to detect and identify crop disease latent period symptoms. Texture features more significantly revealed the characteristics of the latent period of the disease compared to spectral features, effectively improving the detection performance of the model. The research results in this article can provide theoretical references for monitoring and identifying other crop disease latent period symptoms.

Immobilized enzyme-based enzyme electrode biosensors, characterized by high sensitivity and efficiency, strong specificity, and compact size, demonstrate broad application prospects in life science research, disease diagnosis and monitoring, etc. Immobilization of enzyme is a critical step in determining the performance (stability, sensitivity, and reproducibility) of the biosensors. Random immobilization (physical adsorption, covalent cross-linking, etc.) can easily bring about problems, such as decreased enzyme activity and relatively unstable immobilization. Whereas, directional immobilization utilizing amino acid residue mutation, affinity peptide fusion, or nucleotide-specific binding to restrict the orientation of the enzymes provides new possibilities to solve the problems caused by random immobilization. In this paper, the principles, advantages and disadvantages and the application progress of enzyme electrode biosensors of different directional immobilization strategies for enzyme molecular sensing elements by specific amino acids (lysine, histidine, cysteine, unnatural amino acid) with functional groups introduced based on site-specific mutation, affinity peptides (gold binding peptides, carbon binding peptides, carbohydrate binding domains) fused through genetic engineering, and specific binding between nucleotides and target enzymes (proteins) were reviewed, and the application fields, advantages and limitations of various immobilized enzyme interface characterization techniques were discussed, hoping to provide theoretical and technical guidance for the creation of high-performance enzyme sensing elements and the manufacture of enzyme electrode sensors.

ObjectiveTomatoes are one of the highest-yielding and most widely cultivated economic crops globally, playing a crucial role in agricultural production and providing significant economic benefits to farmers and related industries. However, early blight in tomatoes is known for its rapid infection, widespread transmission, and severe destructiveness, which significantly impacts both the yield and quality of tomatoes, leading to substantial economic losses for farmers. Therefore, accurately identifying early symptoms of tomato early blight is essential for the scientific prevention and control of this disease. Additionally, visualizing affected areas can provide precise guidance for farmers, effectively reducing economic losses. This study combines hyperspectral imaging technology with machine learning algorithms to develop a model for the early identification of symptoms of tomato early blight, facilitating early detection of the disease and visual localization of affected areas. MethodsTo address noise interference present in hyperspectral images, robust principal component analysis (RPCA) is employed for effective denoising, enhancing the accuracy of subsequent analyses. To avoid insufficient information representation caused by the subjective selection of regions of interest, the Otsu’s thresholding method is utilized to extract tomato leaves effectively from the background, with the average spectrum of the entire leaf taken as the primary object of study. Furthermore, a comprehensive spectral preprocessing workflow is established by integrating multivariate scatter correction (MSC) and standardization methods, ensuring the reliability and effectiveness of the data. Based on the processed spectral data, a discriminant model utilizing a linear kernel function support vector machine (SVM) is constructed, focusing on characteristic wavelengths to improve the model's discriminative capability. ResultsCompared to full-spectrum modeling, this approach results in an 8.33% increase in accuracy on the test set. After optimizing the parameters of the SVM model, when C=1.64, the accuracies of the training set and test set reach 91.67% and 94.44%, respectively, demonstrating a 1.19% increase in training set accuracy compared to the unoptimized model, while maintaining the same accuracy on the test set, effectively alleviating issues of underfitting. ConclusionThis study successfully establishes an early discriminant model for tomato early blight using hyperspectral imaging and achieves visualization of early symptoms. Experimental results indicate that the SVM discriminant model based on characteristic wavelengths and a linear kernel function can effectively identify early symptoms of tomato early blight. Visualization of these symptoms in terms of disease probability allows for a more intuitive detection of early diseases and timely implementation of corresponding control measures. This visual analysis not only enhances the efficiency of disease identification but also provides farmers with more straightforward and practical information, aiding them in formulating more reasonable prevention strategies. These research findings provide valuable references for the early identification and visualization of plant diseases, holding significant practical implications for monitoring, identifying, and scientifically preventing crop diseases. Future research could further explore how to apply this model to disease detection in other crops and how to integrate IoT technology to create intelligent disease monitoring systems, enhancing the scientific and efficient management of crops.

[Objective] To compare next generation sequencing (NGS) library construction technology between probe hybridization capture and amplicon methods, and analyze the influencing factors of HLA genotyping resolution level and its prospects in clinical applications. [Methods] A total of 207 clinical samples with known typing results and samples from the proficiency testing plan were selected. The conformity rate of HLA genotyping results, allele coverage and typing data analysis indicators were confirmed, and the effects of two library construction methods on the level of HLA genotyping discrimination were compared. [Results] The concordance rate of 207 samples with the feedback results of PT or prior well-characterized HLA genotypes was 100%. Among them, 91 samples were captured using hybridization probe capture method. Compared with the original amplicon method, the hybridization probe capture method can distinguish the alleles of DRB1 and DPB1 that cannot be determined in 13 samples. The allelic imbalance of DRB1, DPA1, and DQB1 loci in 6 samples was resolved. Three samples were found to have missed detection of alleles at the DQA1 and DQB1 loci. [Conclusion] The performance indicators of hybridization probe capture and amplicon performance confirmation meet the requirements of clinical detection of HLA genotyping, which provides an experimental method and basis for clinical application.

Objective:
To understand the status and related factors of knowledge, attitude and practice (KAP) on vision health among young children s parents in Bao an District, Shenzhen, so as to provide reference for further controlling myopia and promoting children s visual health.
Methods:
From May 16th to 26th, 2024, a stratified cluster random sampling method was used to conduct an online questionnaire survey on 7 666 parents of kindergarten children across 41 kindergartens in a street of Bao an District, Shenzhen. The t-test, variance analysis and multiple linear regression analysis were used to analyze the related factors of KAP on vision health among children s parents.
Results:
The pass rates of parental vision KAP and overall assessment were 25.10%, 98.49 %, 71.18% and 58.26%, respectively. The results of the multiple linear regression analysis showed that only fathers with myopia, only mothers with myopia, both parents with myopia, children in the bottom classes, middle classes, senior classes, and pre school had higher standardized scores for KAP on vision health among parents ( β=0.08, 0.11, 0.16, 0.17, 0.16, 0.16, 0.05, P <0.05), compared to both parents without myopia and children in daycare classes. Parents of young children with myopia, and who didn t know their children s visual acuity and their own visual acuity had a lower KAP standardized scores ( β=-0.02, -0.04, -0.05 , P< 0.05).
Conclusions
Young children s parents in Bao an District hold a positive attitude towards vision health, but are lack of knowledge and practice. It is imperative to transmit accurate information and concepts about children s vision health to parents in a targeted manner. In particular, knowledge and guidance should be strengthened for children s parents.

ObjectiveTo investigate the mechanism of Tangbikang dry paste in the prevention and treatment of type 2 diabetic peripheral neuropathy (DPN) based on the glyoxalase-1 (GLO-1)/advanced glycation end products (AGE)/receptor for advanced glycation end products (RAGE) pathway. MethodsA total of 56 Sprague-Dawley rats were randomly divided, with eight assigned to the normal group. The remaining 48 rats were fed a high-fat diet combined with intraperitoneal injection of streptozotocin (STZ) to induce a type 2 diabetes mellitus (T2DM) model. Based on blood glucose levels, the rats were randomly assigned to the model group, Tanglin group (13.5 mg·kg-1), metformin group (135 mg·kg-1), and Tangbikang dry paste low-, medium-, and high-dose groups (3, 6, 12 g·kg-1). Successful modeling of DPN was confirmed by a decrease in mechanical pain threshold in the model group at week 4. Fasting blood glucose, body weight, and mechanical pain threshold were measured every 4 weeks. After 16 weeks of intervention, the pathological morphology of the sciatic nerve was observed using hematoxylin-eosin (HE) staining. The expression of RAGE, AGE, protein kinase C (PKC), and collagen (COL) in the sciatic nerve was assessed by immunohistochemistry. The mRNA expression of RAGE, PKC, Toll-like receptor (TLR), COL, and GLO-1 was detected using real-time quantitative PCR (Real-time PCR). Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), urea (UREA), interleukin-6 (IL-6), and tumor necrosis factor (TNF)-α were measured by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the normal group, the model group showed significantly increased fasting blood glucose (P<0.01), decreased body weight and mechanical pain threshold (P<0.01), and elevated serum AST, ALT, CREA, UREA, IL-6, and TNF-α levels (P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was significantly increased (P<0.01), while COL expression was decreased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was upregulated (P<0.01), whereas COL and GLO-1 mRNA levels were downregulated (P<0.01). Histological examination showed irregular nerve morphology, axonal alterations, and myelin degeneration. Compared with the model group, fasting blood glucose levels in the Tangbikang dry paste high-dose group at all time points and in the medium-dose group at weeks 4 and 16 were significantly reduced (P<0.05, P<0.01). No significant changes in body weight were observed across all Tangbikang dose groups. The mechanical pain threshold was elevated at different time points after administration in all Tangbikang groups (P<0.05, P<0.01). Serum IL-6 and TNF-α levels were decreased in all dose groups (P<0.05, P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was reduced (P<0.01), while COL expression was increased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was downregulated (P<0.01), whereas GLO-1 mRNA expression was upregulated (P<0.05, P<0.01). Additionally, COL mRNA expression was significantly increased in the low- and high-dose groups (P<0.01). Pathological changes in the sciatic nerve were milder in all Tangbikang groups compared to the model group. ConclusionTangbikang dry paste significantly improves DPN, and its mechanism may be associated with the regulation of the GLO-1/AGE/RAGE signaling pathway.

Objective:
To investigate the efficacy of interpersonal synchronous intervention on improving social behavioral deficits in children with autism spectrum disorder (ASD), in order to provide effective guidance for optimizing social intervention programs for ASD children.
Methods:
From September 2022 to March 2023, 84 ASD children aged 7-12 years were recruited from the Children and Adolescents Mental Health Medical Center of Inner Mongolia Autonomous Region Mental Health Center. The test subjects were randomly divided into an intervention group (42 cases) and a control group (42 cases). A 7month social interactive game intervention plan was implemented in the intervention group, with an average of 2 times per week, each lasting 70 minutes, for a total of 56 interventions; the control group only participates in routine social activites such as daily communication and cooperation. And tests were conducted on communication behavior indicators (language expression, language comprehension, and cognitive speaking) and maladaptive behavior indicators (action characteristics, emotional expression, and social communication) of two groups of ASD children before and after intervention, and the differences in various social behavior indicators between the two groups of ASD children before and after intervention were compared through paired sample ttest.
Results:
Before the intervention, there were no significant differences in language expression, language understanding and cognitive oral scores of children with ASD between the intervention and control groups (t=1.43, 1.65, 1.67, P>0.05). The language expression (76.29±2.34) and cognitive speaking (84.24±2.13) scores of the intervention group before intervention were lower than those after intervention (79.28±3.16, 88.39±2.35) (t=-4.17, -4.66), and the language understanding score (85.64 ± 2.30) was higher than that after intervention (83.33±1.28) (t=5.41)(P<0.05). Before intervention, there were no statistically significant differences in non adaptive behavior factors (motor characteristic, emotional expression, and social communication)between groups (t=1.05, 1.46, 1.69, P>0.05). After intervention, the intervention group had higher scores in motor characteristics (79.55±3.32), emotional expression (73.20±3.21), and social communication (78.22±4.05) compared to the control group (72.24±3.43, 69.33±4.18, 76.21±3.14) (t=7.10, 5.51, 4.24, P<0.05).
Conclusion
The interpersonal synchronous intervention program has shown good improvement in the treatment of social behavior disorders in children with ASD.
