ObjectiveGastrodia elata has evolved ecological types with shortened rhizome internodes and diversified flower and fruit coloration in response to different altitudes. Studying the genetic mechanisms of different ecotype germplasm is significant for guiding variety breeding in different cultivation areas. MethodsThe bHLH gene family was identified based on the whole-genome datasets of G. elata f. elata and G. elata f. glauca. Subsequently， the gene family members were subject to analysis， including gene structure， chromosomal localization， cis-acting elements， gene synteny， and phylogeny. Combined with transcriptome data and quantitative Real-time PCR， the expression patterns of bHLH genes in the stems of the different G. elata ecotype germplasm were analyzed. Finally， correlation analysis was conducted between gene expression patterns and color to obtain the key bHLH genes regulating the color formation of stem. ResultsA total of 63 bHLH genes were identified in both G elata f. elata and G. elata f. glauca， unevenly distributed across 17 chromosomes and clustered into 16 subfamilies， with significant expansion in some family members. Obvious inversions of bHLH genes on the same chromosome and interchromosomal translocations were detected in the two ecotype germplasm. Among these genes， 12 bHLH genes （such as bHLH62-3 and bHLH74） were associated with the bright yellow color of G elata f. elata stem， while 9 bHLH genes （such as PIL13， UNE12， and bHLH130） were correlated with the red color of G. elata f. glauca stem. Compared to G. elata f. glauca， the bHLH48 expression level was significantly higher in flowers and scale leaves of G elata f. elata， and the bHLH62-3 expression level was significantly higher in all organs of G elata f. elata. ConclusionsFunctional pathway divergence of the bHLH family members has occurred across different chromosomes in G elata f. elata and G. elata f. glauca. Through synergism or antagonism with other genes， 21 bHLH genes participate in the coloration metabolic pathway regulation of stems， flowers， and fruits. Specifically， bHLH62-3 is involved in regulating stem color differentiation in the anthocyanin biosynthesis pathway of G. elata， thus relevant to the color formation of stem. Additionally， GebHLH48 positively regulates flowering-related pathways to promote the early-flowering phenotype of G. elata f. elata. These findings have laid the foundation for analyzing the genetic regulatory mechanisms underlying the color formation of the G. elata stem.

Objective:To establish and validate a multimodal model based on radiomics and deep learning for predicting acute pancreatitis (AP) complicated with acute respiratory distress syndrome (ARDS).Methods:Patients diagnosed with AP from The First Affiliated Hospital of Soochow University, Donghai County People's Hospital and Jintan Affiliated Hospital of Jiangsu University between January 2017 and December 2023 were enrolled. Based on the diagnosis of ARDS within 1 week after admission, the patients were classified into the ARDS group and the non-ARDS group. Patients in the First Affiliated Hospital of Soochow University ( n=406) was used as the training set (non-ARDS group n=212 vs ARDS group n=194), while Donghai and Jintan hospitals served as the test set ( n=175; non-ARDS group n=104 vs ARDS group n=71). Clinical data, laboratory tests and the occurrence of systemic inflammatory response syndrome (SIRS) within 24 hours after admission were collected. Scoring systems such as bedside index for severity in acute pancreatitis (BISAP), Ranson score and modified CT severity index (MCTSI) were calculated. Radiomics features were extracted from three-dimensional CT images to develop a radiomics model based on XGBoost algorithm. At the same time, a deep learning model was constructed using deep convolutional networks to extract deep features. Finally, clinical features and the predictions from the aforementioned models were integrated to establish a multimodal model based on XGBoost algorithm. To enhance model visualization, variable importance ranking and local interpretable visualization were used. The receiver operating characteristic (ROC) curves of the three models and the three scores including BISAP, Ranson and MCTSI were plotted and the area under the curves (AUCs) were calculated to evaluate the prediction performance for ARDS in AP patients, as well as sensitivity and specificity. Results:In the multimodal model for predicting ARDS in AP patients, predictions of the deep learning model and the radiomics model were the most important variables, followed by SIRS, C-reactive protein, procalcitonin, albumin, glucose, creatinine, neutrophil, and Ca 2+. In the training set, the multimodal model achieved an AUC of 0.933 for predicting ARDS in AP patients, higher than the radiomics model (0.727), the deep learning model (0.877), MCTSI (0.870), Ranson (0.620) and BISAP (0.898). In the test set, the model's AUC was 0.916 for predicting ARDS in AP patients, higher than the radiomics model (0.660), the deep learning model (0.864), MCTSI (0.851), Ranson (0.609), and BISAP (0.860). Conclusions:Based on clinical structured data, radiomics and deep learning features, the multimodal model could predict the risk of ARDS in AP patients at an early stage, whose performance is better than the single-modal models and the traditional scoring systems.

Objective To investigate the effects of two driving pressure-based methods to set positive end-expiratory pressure on pulmonary mechanics and oxygenation in patients undergoing laparoscopic and thoracoscopic esophagectomy.Methods Sixty patients undergoing laparoscopic and thoracoscopic esophagectomy were divided into two groups(n=30 each):incremental group(group Ⅰ)and decremental group(group D).PEEP titration was performed in both groups during thoracoscopy and laparoscopy.Respiratory mechanics parameters,hemodynamic parameters,and blood gas analysis were collected for analysis before preoxygenation(T0),10 minutes after intuba-tion(T1),20 minutes after PEEP application for one-lung ventilation(T2),20 minutes after PEEP application for two-lung ventilation(T3),before extubation(T4),and 30 minutes after extubation(Ts).The postoperative pulmonary complications within 3 days and 7 days after operation,hospitalization duration,and costs were recorded.Results Compared with group Ⅰ,patients in group D showed higher oxygenation index and pulmonary compliance during surgery(P＜0.05).In both groups,driving pressure decreased and compliance increased after PEEP titration(P＜0.05).Conclusion Both driving pressure-guided incremental and decremental titration of individualized PEEP improved intraoperative respiratory mechanics in patients undergoing laparoscopic and thoracoscopic esopha-gectomy,and decremental titration was more effective in improving intraoperative respiratory mechanics and oxygenation in patients during operation.

Objective:To explore the effect of kidney-strengthening and blood stasis-eliminating formula on nutritional status and quality of life in patients with osteoporosis combined with hemodialysis.Methods:From January 2024 to January 2025,60 patients with liver and kidney yin deficiency and blood stasis obstruction were selected from the Pizhou City Traditional Chinese Medicine Hospital's Hemodialysis Center.60 patients were randomly divided into two groups,30 in each group.The matched group received general treatment plus paricalcitol,while the treatment group received the same treatment plus Yishen Zhuyu Fang(a traditional Chinese medicine formula for kidney and blood stasis).The treatment course lasted 12 weeks.Changes in TCM syndrome scores,the Modified Subjective Global Assessment(MQSGA),the Kidney and Life Quality(KDQOLTM-36)scale,lipid levels,and nutritional indicators were compared before and after treatment.Results:After treatment,the TCM syndrome scores in both groups decreased(P＜0.05),with a more pronounced decrease in the treatment group(P＜0.05).The KDQOLTM-36 score in the treatment group increased(P＜0.05),while the increase was not significant in the matched group(P＞0.05),indicating that the treatment group performed better than the matched group(P＜0.05).Both groups experienced a decrease in the MQSGA score(P＜0.05),although the difference was not statistically significant(P＞0.05),the treatment group showed a more noticeable decline.The TC,TG,LDL,and TG/HDL levels in the treatment group all decreased significantly,while HDL levels increased(P＜0.05).In contrast,the TC and HDL levels in the matched group did not change(P＞0.05),while the TG,LDL,and TG/HDL levels increased(P＜0.05).The treatment group performed significantly better than the matched group(P＜0.05).The TRF,Hb,and ALB levels in the treatment group increased(P＜0.05),while the increase was not significant in the matched group(P＞0.05).The total effective rate of the treatment group was 90％,higher than the matched group(23.3％)(P＜0.05).Conclusion:The formula of tonifying the kidney and removing stasis can improve the nutritional status and quality of life of patients with liver and kidney yin deficiency and blood stasis obstruction in hemodialysis combined with osteoporosis.

Aim To perform high-throughput screen-ing of immunomodulatory traditional Chinese medicine(TCMs)based on an in vitro B cell differentiation-antibody secretion model,identifying active herbal candidates with immune-enhancing properties to pro-vide novel therapeutic options and theoretical support for influenza virus treatment in immunocompromised in-dividuals.Methods B cells were stimulated with dif-ferent concentrations of cytosine-phosphate-guanine oli-godeoxynucleotide 2006(CpG)and nterleukin-2(IL-2)to promote proliferation,differentiation,and anti-body secretion,and the effects of varying concentra-tions of the solvent DMSO were also evaluated.The op-timal conditions for the B cell differentiation-anti-body secretion model were determined based on the se-cretion levels of three antibody isotypes.The feasibility of the model was further validated using rapamycin,a known B cell function inhibitor.On this basis,a high-throughput screening platform for immunomodulatory a-gents was optimized and established.Subsequently,the immune-enhancing activity of 465 polarity extract from TCMs was evaluated.Results The optimal con-ditions for the model were determined as 2 mg·L-1 CpG,1.67 × 106 nkat·L-1 IL-2,and DMSO with a volume fraction of 0.1％.Rapamycin effectively inhib-ited B cell differentiation into plasmablast and signifi-cantly reduced antibody production,indicating the reli-ability of the model.Multiple rounds of screening re-vealed that the dichloromethane extract of licorice,the dichloromethane extract of Vinegar-processed Curcumae Rhizoma,the cyclohexane extract of Honey-prepared Radix Asteris,and the aqueous extract of Siphonostegia chinensis Benth were identified to significantly promote both B cell proliferation and differentiation and anti-body secretion at a concentration of 600 μg·L-1.Conclusion This study successfully optimizes an in vitro B cell differentiation-antibody secretion model and identifies several TCM extracts,including licorice,with potential immune-enhancing activity.

Objective:This study aims to explore the job preferences of county-level Centers for Disease Control and Prevention(CDC)personnel and to provide a basis for the development of effective incentive mechanisms.Methods:This study used a combination of stratified sampling and latent class sampling to investigate 1 809 respondents from 56 county-level CDCs in Shandong Province,Hubei Province,and Guizhou Province.Data were analysed using a mixed logit model and a latent class model,and willingness to pay was calculated.Results:The results of the mixed logit model showed that,all attributes and their levels had a significant influence(P<0.05),with establishment being the most important motivating factor(β=2.249).In the latent class model,respondents were divided into three categories.The main differences between the three classes were the choice of exit options and differences in preferences for job attributes.Conclusion:County-level CDC personnel preferred jobs with higher incomes,very good benefit levels,establishment,low workload,better recognition and respect from the public,more opportunities for career advancement,and abundant training opportunities.It is recommended that the total number of establishment should be rationally controlled and dynamically adjusted to balance the differences between working conditions within and outside the establishment;that a comprehensive approach should be adopted to improve both hygiene and motivation factors;and that different incentives should be adopted for different categories of CDC staff. Those who are willing to make a change should be provided with more opportunities for training and career advancement.
