Panax species are mostly valuable medicinal plants. While some species' seeds are sensitive to dehydration, the dehydration tolerance of seeds from other Panax species remains unclear. The phospholipase D(PLD) gene plays an important role in plant responses to dehydration stress. However, the characteristics of the PLD gene family and their mechanisms of response to dehydration stress in seeds of Panax species with different dehydration tolerances are not well understood. This study used seeds from eight Panax species to measure the germination rates and PLD activity after dehydration and to analyze the correlation between dehydration tolerance and seed traits. Bioinformatics analysis was also conducted to characterize the PnPLD and PvPLD gene families and to evaluate their expression patterns under dehydration stress. The dehydration tolerance of Panax seeds was ranked from high to low as follows: P. ginseng, P. zingiberensis, P. quinquefolius, P. vietnamensis var. fuscidiscus, P. japonicus var. angustifolius, P. japonicus, P. notoginseng, and P. stipuleanatus. A significant negative correlation was found between dehydration tolerance and seed shape(three-dimensional variance), with flatter seeds exhibiting stronger dehydration tolerance(r=-0.792). Eighteen and nineteen PLD members were identified in P. notoginseng and P. vietnamensis var. fuscidiscus, respectively. These members were classified into five isoforms: α, β, γ, δ, and ζ. The gene structures, subcellular localization, physicochemical properties, and other characteristics of PnPLD and PvPLD were similar. Both promoters contained regulatory elements associated with plant growth and development, hormone responses, and both abiotic and biotic stress. During dehydration, the PLD enzyme activity in P. notoginseng seeds gradually increased as the water content decreased, whereas in P. vietnamensis var. fuscidiscus, PLD activity first decreased and then increased. The expression of PLDα and PLDδ in P. notoginseng seeds initially increased and then decreased, whereas in P. vietnamensis var. fuscidiscus, the expression of PLDα and PLDδ consistently decreased. In conclusion, the dehydration tolerance of Panax seeds showed a significant negative correlation with seed shape. The dehydration tolerance in P. vietnamensis var. fuscidiscus and dehydration sensitivity of P. notoginseng seeds may be related to differences in PLD enzyme activity and the expression of PLDα and PLDδ genes. This study provided the first systematic comparison of dehydration tolerance in Panax seeds and analyzed the causes of tolerance differences and the optimal water content for long-term storage at ultra-low temperatures, thus providing a theoretical basis for the short-term and ultra-low temperature long-term storage of medicinal plant seeds with varying dehydration tolerances.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

Objective To explore characteristics of clinical parameters and cytokines in patients with drug-induced liver injury(DILI)caused by different drugs and their correlation with clinical indicators. Method The study was conducted on patients who were up to Review of Uncertainties in Confidence Assessment for Medical Tests(RUCAM)scoring criteria and clinically diagnosed with DILI.Based on Chinese herbal medicine,cardiovascular drugs,non-steroidal anti-inflammatory drugs(NSAIDs),anti-infective drugs,and other drugs,patients were divided into five groups.Cytokines were measured by Luminex technology.Baseline characteristics of clinical biochemical indicators and cytokines in DILI patients and their correlation were analyzed. Results 73 patients were enrolled.Age among five groups was statistically different(P=0.032).Alanine aminotransferase(ALT)(P=0.033)and aspartate aminotransferase(AST)(P=0.007)in NSAIDs group were higher than those in chinese herbal medicine group.Interleukin-6(IL-6)and tumor necrosis factor alpha(TNF-α)in patients with Chinese herbal medicine(IL-6:P<0.001;TNF-α:P<0.001)and cardiovascular medicine(IL-6:P=0.020;TNF-α:P=0.001)were lower than those in NSAIDs group.There was a positive correlation between ALT(r=0.697,P=0.025),AST(r=0.721,P=0.019),and IL-6 in NSAIDs group. Conclusion Older age may be more prone to DILI.Patients with NSAIDs have more severe liver damage in early stages of DILI,TNF-α and IL-6 may partake the inflammatory process of DILI.

Objective To develop an intelligent model for differential diagnosis of atrioventricular nodal re-entrant tachycardia(AVNRT)and atrioventricular re-entrant tachycardia(AVRT)using 12-lead wearable electrocardiogram devices.Methods A total of 356 samples of 12-lead supraventricular tachycardia(SVT)electrocardiograms recorded by wearable devices were randomly divided into training and validation sets using 5-fold cross validation to establish the intelligent classification model,and 101 patients with the diagnosis of SVT undergoing electrophysiological studies and radiofrequency ablation from October,2021 to March,2023 were selected as the testing set.The changes in electrocardiogram parameters before and during induced tachycardia were compared.Based on multiscale deep neural network,an intelligent diagnosis model for classifying SVT mechanisms was constructed and validated.The 3-lead electrocardiogram signals from Ⅱ,Ⅲ,and V1 were extracted to build new classification models,whose diagnostic efficacy was compared with that of the 12-lead model.Results Of the 101 patients with SVT in the testing set,68 were diagnosed with AVNRT and 33 were diagnosed with AVRT by electrophysiological study.The pre-trained model achieved a high area under the precision-recall curve(0.9492)and F1 score(0.8195)for identifying AVNRT in the validation set.The total F1 scores of the lead Ⅱ,Ⅲ,V1,3-lead and 12-lead intelligent diagnostic models in the testing set were 0.5597,0.6061,0.3419,0.6003 and 0.6136,respectively.Compared with the 12-lead classification model,the lead-Ⅲ model had a net reclassification index improvement of-0.029(P=0.878)and an integrated discrimination index improvement of-0.005(P=0.965).Conclusion The intelligent diagnostic model based on multiscale deep neural network using wearable electrocardiogram devices has an acceptable accuracy for classifying SVT mechanisms.

Objective:To investigate the factors influencing mortality within one year following hip fracture surgery in elderly patients.Methods:This study retrospectively analyzed clinical data from 1 263 elderly patients with hip fractures who underwent surgery at the First Affiliated Hospital of Air Force Medical University between January 2014 and December 2022.Based on their survival status one-year post-surgery, the patients were categorized into two groups: the death group(212 cases)and the survival group(1 051 cases).Univariate and multivariate logistic regression models were employed to identify factors associated with 1-year mortality.Results:The 1-year mortality rate was found to be 16.78%.Multivariate logistic regression analysis identified several significant predictors of 1-year mortality in elderly patients with hip fractures.These predictors include gender( OR=0.67, 95% CI: 0.48-0.95), age greater than 85 years( OR=2.23, 95% CI: 1.56-3.19), body mass index(BMI)less than 18.5( OR=1.74, 95% CI: 1.17-2.60), BMI between 30 and 40( OR=3.14, 95% CI: 1.20-8.21), history of stroke( OR=1.59, 95% CI: 1.06-2.38), presence of anemia( OR=1.75, 95% CI: 1.07-2.86), fibrinogen(FIB)levels either below 1.8 or above 3.5( OR=1.63, 95% CI: 1.12-2.37), deep vein thrombosis( OR=1.57, 95% CI: 1.13-2.18), and American Society of Anesthesiologists(ASA)grade Ⅲ/Ⅳ( OR=2.37, 95% CI: 1.56-3.59). Conclusions:In elderly patients with hip fractures, age over 85 years, a BMI less than 18.5 or between 30 and 40, the presence of stroke, anemia, FIB levels below 1.8 or above 3.5, deep vein thrombosis(DVT), and ASA classifications Ⅲ or Ⅳ are identified as independent risk factors for 1-year mortality.Conversely, being female serves as a protective factor.

Objective To investigate the effect of individual exercise training on the rehabilitation of patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods A total of 81 patients between January 2021 and December 2023 were randomly allocated into an observation group(n=41)and a control group(n=40)using a simple random number Tab.method.The control group received routine post-operative rehabilitation intervention,while the observation group received individualized exercise training as the core component of cardiac rehabilitation intervention.The study compared the effects of rehabilitation,cardiac function parameters[left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD)],exercise endurance measures[6-minute walking distance(6MWD)],and quality of life assessed by Seattle Angina Pecina Scale(SAQ)scores between the two groups before and after a three-month intervention period.Results The total recovery response rate in the observation group was higher than that in the control group(P＜0.05).LVEF,LVEDD,6 MWD,maximum exercise load and SAQ scales(P＞0.05),LVEF were higher than before intervention(t=3.345,2.480,3.165,5.016,2.059,4.582,4.443,3.353,P＜0.05),and LVEDD was lower than before intervention(t=3.335,P＜0.05).Conclusion The individualized exercise training-based cardiac rehabili-tation program demonstrates potential for enhancing cardiac function and exercise endurance in patients with CHD following PCI,thereby improving their overall quality of life.This finding holds significant clinical implications.

Objective:To explore the effect of staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair.Methods:From January 2021 to December 2022, convenience sampling was used to select 73 patients who underwent arthroscopic rotator cuff repair in the Department of Hand Surgery at Affiliated Hospital of Nantong University as participants. According to the random number table method, patients were divided into a control group ( n=36) and an observation group ( n=37). Control group received routine rehabilitation nursing, while observation group received staged rehabilitation nursing. The University of California, Los Angeles (UCLA) Shoulder Rating Scale score, American Shoulder and Elbow Surgeons (ASES) Rating Scale score, Constant-Murley Shoulder Scale score, and complications during rehabilitation were compared between two groups of patients before and six months after intervention. Results:Six months after surgery, both groups showed an increase in UCLA scores and ASES scores compared to before the intervention ( P<0.05), and the scores of observation group were higher than those of control group, with statistical differences ( P<0.05). Six months after surgery, the Constant-Murley Shoulder Scale scores for daily life and shoulder range of motion in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05). During the rehabilitation period, the incidence of complications in observation group was lower than that in control group with a statistical difference ( P<0.05) . Conclusions:Staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair shows significant effects and can effectively promote patient recovery.
