The auxin/indole-3-acetic acid (Aux/IAA) gene family is an important regulator for plant growth hormone signaling, involved in plant growth, development, as well as response to environmental stresses. In the present study, we identified SmIAA7 which is potentially associated with Salvia miltiorrhiza leaf development through comparatively analyzed the transcriptome data from different pinnate leaves. SmIAA7 was successfully isolated from S. miltiorrhiza using the specific primers. Then subsequent bioinformatic analysis, prokaryotic expression and purification, subcellular localization, and induction expression analysis under auxin and abiotic stress were performed. The full-length of SmIAA7 contained an ORF of 684 bp encoding a protein of 227 amino acid with a molecular weight of 25.3 kD. Conserved domain analysis showed that SmIAA7 contains the conserved Aux_IAA domain (pfam02309). Sequence analysis and phylogenetic tree analysis results indicated SmIAA7 was phylogenetically close to IAA7 and IAA14 from other plants, suggesting SmIAA7 involved in plant growth and development as well as response to environmental stresses. The prokaryotic expression vector pET28a-SmIAA7 was constructed and SmIAA7 recombinant protein was successfully expressed in E. coli Rosetta (DE3) strain. Subcellular localization experiment demonstrated that SmIAA7 localized in the nucleus of plant cells. Real-time fluorescence quantitative PCR results showed that the expression level of SmIAA7 was upregulated in response to auxin. Drought, low temperature, and salt stress significantly increased the transcript level of SmIAA7 gene. This study lays a foundation for further elucidating the role of SmIAA7 in leaf development, signal transduction, and stress defense in S. miltiorrhiza.

OBJECTIVE To re-evaluate the use of systematic evaluation/meta-analysis of anti-VEGF drugs in the treatment of diabetic macular oedema （DME）， aiming to provide evidence-based support for the clinical application of this medication. METHODS A comprehensive search was conducted across a range of databases， including CNKI， Wanfang data， VIP， CBM， PubMed， Web of Science， Embase， and Cochrane Library. The objective was to identify systematic evaluation/meta-analysis of anti- VEGF drugs for DME， with search time from the inception of the databases to March 2024. The report quality， methodological quality， and evidence quality were assessed by using PRISMA2020 statement， AMSTAR2 scale and GRADE tool. A comprehensive analysis of systematic evaluation/meta-analysis results was also conducted. RESULTS A total of 22 articles were included. According to the PRISMA2020 statement evaluation， 13 studies provided relatively complete information （≥21 points）， while 9 studies had information deficiencies （18-＜21 points）. The AMSTAR 2 scale evaluation revealed that 21 studies had very low methodological quality， and one study had low methodological quality. The GRADE tool evaluation showed that out of 89 outcome indicators， 28（ 31.46%） were classified as high-quality evidence， 34（ 38.20%） as moderate-quality evidence， 24（ 26.97%） as low- quality evidence， and 3 （3.37%） as very low-quality evidence. The comprehensive quality analysis results demonstrated that， compared with laser photocoagulation， anti-VEGF drugs significantly enhanced the improvement in best-corrected visual acuity （BCVA）， as well as significant change in retinal thickness at 1 and 6 months， and 1 and 2 years post-treatment， and also in BCVA and retinal thickness at 1， 3， and 6 months post-treatment （P＜0.05）. Compared with placebo， patients treated with anti-VEGF drugs showed significant improvement in BCVA after 1 year of treatment （P＜0.05）. However， when compared with corticosteroid drugs， patients treated with anti-VEGF drugs exhibited a significant increase in retinal thickness after 6 months of treatment （P＜0.05）. Compared with corticosteroid drugs， the incidence of adverse events related to the eyes， cataract formation and intraocular pressure were significantly decreased in patients treated with anti-VEGF drugs （P＜0.05）. Compared with laser photocoagulation， the incidence of ocular adverse events was significantly decreased in patients treated with anti-VEGF drugs， while the incidence of fatal adverse events was significantly increased （P＜0.05）. CONCLUSIONS Anti-VEGF therapy for DME may possess certain advantages in terms of efficacy and safety， but it is associated with a higher risk of fatal adverse events； the evidence included in systematic reviews/meta-analyses is of moderate to high quality.

Objective: To analyze the demographic characteristics of patients with red blood cell transfusion reactions, the usage of red blood cell preparations, and the differences in the composition ratio of adverse reactions based on multi-center data from the Haemovigilance Network, in order to reveal the clinical characteristics of red blood cell transfusion and its underlying issues. Methods: Clinical data of patients who experienced transfusion reactions after red blood cell transfusion in the Haemovigilance Network from 2018 to 2023 were collected. The demographic characteristics of patients who experienced transfusion reactions with different types of red blood cell preparations, the utilization of these preparations, and the differences of the composition ratios of transfusion reactions were analyzed. Count data were expressed as numbers (n) or percentages (%), and comparisons between groups were performed using the Chi-square test. Results: Red blood cell transfusion reactions were more common in females (53.56%), with the majority of patients aged 50-69 years (35.54%). The Han polulation accounted for the vast majority of patients (92.77%), and patients in the hematology and obstetrics/gynecology departments had a relatively high proportion of transfusion reactions (13.26% and 14.26%, respectively). Leukocyte-reduced red blood cells and suspended red blood cells were the most common types of transfusion reactions reported among red blood cell preparations. Allergic reactions and non-hemolytic febrile reactions were the most common transfusion reactions, and there were significant differences in the composition ratios of allergic reactions (χ =869.89, P<0.05) and non-hemolytic febrile reactions (χ =812.75, P<0.05) across various types of red blood cell preparations. Conclusion: There are differences in the demographic characteristics and composition ratio of transfusion reactions among different red blood cell preparations. The management of red blood cell transfusion reactions should be tailored to patient characteristics and conditions, and the selection and use of blood products should be optimized to reduce or avoid the occurrence of transfusion reactions, such as considering the use of washed red blood cells for patients with a history of transfusion allergies or those prone to allergies.

Cellulose synthase (CesA), one of the key enzymes in the biosynthesis of cellulose in plants, plays an important role in plant growth and plant resistance. In this study, a total of 21 AsCesA genes from Aquilaria sinensis were systematically identified and the physico-chemical characteristics were analyzed based on genome database and bioinformatical methods. The phylogenetic tree was constructed and the gene location on chromosome, cis-acting elements in the 2 000 basepairs upstream regulatory regions and conservative motifs were analyzed. The AsCesA proteins were mainly located on the plasma membrane. The number of amino acids of the proteins ranged from 390 to 1 261. The isoelectric point distributed from 5.67 to 8.86. All of the 21 AsCesA proteins possessed the transmembrane domains, the number of which was from 6 to 8. The genes were classified into 3 groups according to the phylogenetic relationship. Obvious differences were observed in motif composition in genes from different groups. However, motif2, motif6, motif7 and motif10 were observed in all of AsCesA proteins. Analysis of cis-acting elements indicated that AsCesA genes family has cis-acting elements related to plant hormones, abiotic stresses, and biological processes. Seven AsCesA genes with differential expression were selected according to the calli transcriptome data induced by NaCl at different times and their expression levels under different abiotic stresses were analyzed by quantitative real-time PCR. The results indicated that salt, low temperature, drought, and heavy metal stresses could affect the expression level of AsCesA genes, and the abundance of AsCesA1, AsCesA3 and AsCesA20 showed a significant change, implying their potential important roles to the abiotic stresses. The accumulation pattern of cellulose content under different abiotic stresses was similar to the expression trend of AsCesA genes. Our results provide valuable insights into the role of cellulose synthase in A.sinensis in plant defense.

Objective:To study a method for automatically extracting acupuncture and moxibustion prescriptions from clinical literature to assist data mining of acupuncture and moxibustion prescriptions; To support clinical research and decision-making in acupuncture and moxibustion treatment.Methods:The Chinese journal articles on clinical trials of acupuncture and moxibustion in CNKI from January 1, 1992 to December 31, 2022 were searched. The titles and abstracts of 750 articles were randomly selected and manually labeled. The three main entities of disease name, acupuncture and moxibustion method and acupoint of acupuncture and moxibustion prescription were selected. From the data set, 70% was selected as the training set, 15% as the validation set, and 15% as the test set for the experiment. The extraction of acupuncture prescriptions was considered a sequence labeling task. A model for automatic extraction of acupuncture prescriptions was built using a pretrained language model (PLM), and four different PLMs were selected to compare their entity recognition effects. The impact of negative sampling and label smoothing training techniques on the model was further investigated.Results:The model based on eHealth had the highest F1 scores (92.84). During training, if only negative sampling technology was used, F1 value increased to 93.53; if only label smoothing was used, F1 value increased to 93.64; if negative sampling and label smoothing were used simultaneously, F1 value increased to 94.28, an increase of 1.55%. Conclusions:This study proposes a fast and accurate model for extracting acupuncture and moxibustion prescriptions. The research shows that the model recognition effect based on eHealth in the biomedical field is the best, and the recognition effect of the model can be further improved by using negative sampling and label smoothing training techniques.

Objective:To investigate the value of BRAF V600E and multigene detection and stratified application for the diagnosis of thyroid nodules.Methods:A total of 1 117 patients with thyroid nodules resection at Nanjing Gulou Hospital from December 2020 to July 2022 were enrolled in the study. Fine needle aspiration (FNA) and core biopsy samplings were performed for cytopathologic examination and genetic testings; the findings were combined with BSRTC classification. The diagnostic performance of BRAF V600E and multigene detection were compared.Results:Among the 1, 117 patients who underwent thyroid nodules resection, 285 were male and 832 were female, with a median age of 46 years (range: 24-76 years). Postoperative histopathologic examination confirmed 1 040 cases of thyroid cancer and 77 cases of benign nodules. The sensitivity (87.0% vs. 80.8%, P<0.01) and diagnostic accuracy (87.9% vs. 82.1%, P<0.01) of multigene detection were significantly higher than those of BRAF V600E detection. The result of multigene detection showed that BRAF V600E mutation was the most common finding, followed by CCDC6-RET (E1-E12) fusion, ETV6-NTRK3 fusion, and KRAS mutation. Multigene detection had a higher sensitivity (81.9% vs. 72.8%, P<0.01) and lower cancer risk in wild-type (47.6% vs. 57.7%, P=0.069) than BRAF V600E detection in BSRTCⅠ-Ⅴ lesions. Compared with BRAF V600E detection, multigene had no significant difference of sensitivity in BSRTC Ⅰ lesions, but significantly higher sensitivity (86.3% vs 74.0%, P<0.01) in BSRTC Ⅲ lesions. Conclusions:Genetic detection can be used as an effective tool for the diagnosis of thyroid nodules. A stratified application of molecular markers in the diagnosis of thyroid nodules is proposed. Combined with FNA, single gene or multigene detection both can effectively assist in the diagnosis of thyroid nodules. Moreover, multigene detection is superior to single gene detection. For BSRTC Ⅲ lesion with wild-type BRAF, multigene detection can be considered with a repeated FNA.

Corneal transplantation is an effective treatment for corneal blindness, and it is the only hope for patients with corneal blindness. Cornea has no blood vessels and no lymphatic vessels, which is called immune privilege organ, so the success rate of corneal transplantation is significantly higher than that of other organ transplantation, but the rejection reaction after corneal transplantation is still the main reason for the failure of corneal transplantation. The directional movement of immune cells to lymphoid tissue and inflammatory sites is the mainly immune response after organ transplantation. And the regulatory T cells(Treg)play a key role in immune regulation, which can induce immune tolerance by regulating and inhibiting the activation of effector T cells and reduce the rejection reaction after corneal transplantation. In addition, this review also discussed the effectiveness of applying cordyceps sinensis extract FTY720 to enhance the function of Treg. Based on this, we briefly reviewed the sources, mechanism of action and treatment of Treg after corneal transplantation, so as to provide some reference for the subsequent clinical application transformation and basic research.

The breakage pattern of unit particles during the production of oral solid dosage forms (OSD) is closely related to the quality of intermediate or final products. To accurately characterize the particles and study the evolution law of particle breakage, the Bonding model of the discrete element method (DEM) was used to investigate the breakage patterns of model parameters, particle shape and process conditions (loading mode and loading rate) on the dynamic breakage, force-time curve, breakage rate, maximum breakage size ratio and fracture strength of particles. The results showed that the particle breakage force was positively correlated with normal strength and bonded disk scale, negatively correlated with normal stiffness per unit area and tangential stiffness per unit area, and weakly correlated with tangential strength. The particle breakage rate was negatively correlated with the aspect ratio of the particles, and the maximum breakage size ratio was positively correlated with the aspect ratio of the particles; among the three loading modes, the breakage rate of compression breakage model was the largest, the breakage rate of shear breakage model was the second largest, and the breakage rate of wear breakage model was the smallest; the maximum breakage size ratio was positively correlated with the loading rate, the loading mode and the loading rate had no mutual influence on particle breakage rate, but had mutual influence on the maximum breakage size ratio. The research results will provide a theoretical basis for the shift of OSD from batch manufacturing to advanced manufacturing.

WRKY transcription factor is a type of transcription factor unique to plants and plays an important role in various physiological processes of plants. This study is based on the transcriptome data of Atractylodes lancea, the correlation between the FPKM values of the AlWRKY gene and the AlTPS gene of Atractylodes lancea was analyzed. Combined with the analysis results, the candidate gene AlWRKY65 with a significant positive correlation with the expression levels of AlTPS1 and AlTPS6 genes and a relatively high FPKM value was screened. The candidate gene was cloned to obtain the open reading frame ORF of the AlWRKY65 gene, and the related information of its encoded protein was analyzed and the gene expression was studied. The results showed that AlWRKY65 contains a 681 bp open reading frame and encoding 226 amino acids. Through amino acid sequence homology analysis, it was found that AlWRKY65 amino acid sequence had high homology with several plants such as HaWRKY65 and LsWRKY65; AlWRKY65 protein had a typical WRKYGQK domain, belonging to IIe subgroup of WRKY transcription factor family; phylogenetic analysis indicated that AlWRKY65 protein had the higher homology with CcWRKY65 protein; the expression of AlWRKY65 gene in different tissues of two producing areas of Atractylodes lancea were assayed via real-time fluorescence quantitative PCR, and the results showed that all of them were highly expressed in leaves and also has tissue differences. The expression level of AlWRKY65 gene was down-regulated within 48 h of methyl jasmonate (MeJA) induction; subcellular localization and transcriptional activation assay suggested that AlWRKY65 was located in the nucleus and had no transcriptional activation activity. This study provides a reference for further elucidating the biological function of AlWRKY65 in Atractylodes lancea.
