Lateral organ boundaries (LOB) domain (LBD) genes encode a family of transcription factors ubiquitous in higher plants, playing crucial roles in the growth, development, and stress responses. Hippophae rhamnoides, known for its drought, cold, and saline-alkali tolerance, offers significant economic benefits and ecological values. Utilizing the whole genome data and bioinformatics approaches, this study identified and analyzed the LBD gene family in H. rhamnoides. Additionally, we examined the expression pattern of HrLBD genes by integrating the transcriptome data from male and female flower buds in development. Eleven LBD genes were identified in H. rhamnoides, and these genes were distributed on five chromosomes. The HrLBD proteins showed the lengths ranging from 159 aa to 302 aa, the molecular weights between 18 249.91 Da and 33 202.01 Da, and the subcellular localization in the nucleus or chloroplasts. LBD protein domains and gene structures were highly conserved, featuring similar motifs. The phylogenetic analysis of HrLBD genes and the LBD genes in Arabidopsis thaliana and Hordeum vulgare revealed that HrLBD genes falled into two major categories: Class Ⅰ and Class Ⅱ. The transcriptome data and RT-qPCR showed that HrLBD genes were highly expressed in male flower buds, with up-regulated expression levels throughout bud development, indicating a role in the specific stage of male flower bud development. This study lays a theoretical foundation for exploring the roles of HrLBD genes in the growth, development, and sex differentiation of H. rhamnoides flower buds.

Objective To investigate the risk factors associated with prolonged hospitalization in patients diagnosed with diabetic foot ulcers(DFU),to develop a predictive model,and to conduct internal validation of the model.Methods The clinical data of DFU patients admitted to West China Hospital,Sichuan University between January 2012 and December 2022 were retrospectively collected.The subjects were randomly assigned to a training cohort and a validation cohort at a ratio of 7 to 3.Hospital stays longer than 75th percentile were defined as prolonged length-of-stay.A thorough analysis of the risk factors was conducted using the training cohort,which enabled the development of an accurate risk prediction model.To ensure robustness,the model was internally validated using the validation cohort.Results A total of 967 inpatients with DFU were included,among whom 245 patients were identified as having an extended length-of-stay.The training cohort consisted of 622 patients,while the validation cohort comprised 291 patients.Multivariate logistic regression analysis revealed that smoking history(odds ratio[OR]=1.67,95%confidence interval[CI],1.13 to 2.48,P=0.010),Wagner grade 3 or higher(OR=7.13,95%CI,3.68 to 13.83,P＜0.001),midfoot ulcers(OR=1.99,95%CI,1.07 to 3.72,P=0.030),posterior foot ulcers(OR=3.68,95%CI,1.83 to 7.41,P＜0.001),multisite ulcers(OR=2.91,95%CI,1.80 to 4.69,P＜0.001),wound size≥3 cm2(OR=2.00,95%CI,1.28-3.11,P=0.002),and white blood cell count(OR=1.11,95%CI,1.05 to 1.18,P＜0.001)were associated with an increased risk of prolonged length of stay.Additionally,a nomogram was constructed based on the identified risk factors.The areas under the receiver operating characteristic(ROC)curves for both the training cohort and the validation cohort were 0.782(95%CI,0.745 to 0.820)and 0.756(95%CI,0.694 to 0.818),respectively,indicating robust predictive performance.Furthermore,the calibration plot demonstrated optimal concordance between the predicted probabilities and the observed outcomes in both the training and the validation cohorts.Conclusion Smoking history,Wagner grade≥3,midfoot ulcers,posterior foot ulcers,multisite ulcers,ulcer area≥3 cm2,and elevated white blood cell count are identified as independent predictors of prolonged hospitalization.Therefore,it is imperative that clinicians conduct a comprehensive patient evaluation and implement appropriate diagnostic and therapeutic strategies to effectively shorten the length of stay for DFU patients.

Objective:To explore the relevance of a new comprehensive respiratory mechanics parameter, elastic power, to the 28-day prognosis of ARDS patients.Methods:Patients with ARDS hospitalized for at least 48 h with invasive mechanical ventilation in five intensive care units in three local hospitals in Lianyungang City from June 2018 to June 2022 were included in the study. Their baseline data and respiratory mechanics parameters were collected. Elastic power, mechanical power, driving pressure and lung compliance are calculated according to the corresponding formulae. The prognostic risk factors of ARDS patients were analysed using COX multi-factor regression, and the predictive value of EP/Cst on the 28-day prognosis of ARDS patients was evaluated based on ROC curve analysis and Kaplan-Meier survival curve.Results:There was no significantly difference in tidal volume and PEEP settings between the patients in the ARDS survivor and death groups ( P> 0.05). However, the differences in respiratory rate, plateau pressure, driving pressure, lung compliance, mechanical work, elastic work, EP/cst and MP/cst between the two groups were significantly different (all P< 0.01). Multifactorial COX regression analysis showed that EP/cst ( HR=1.211, 95% CI:1.091-1.323) and RR ( HR=1.209, 95% CI:1.046-1.339) were strongly associated with a more severe degree of illness and a worse prognosis in ARDS. And the cumulative survival rate at 28 d was significantly lower in the high Cst-EP group than in the low Cst-EP group (50.00% vs. 82.40%, P < 0.01). Conclusions:The new respiratory mechanics parameters EP and EP/Cst can assess the severity of ARDS with a good predictive effect on patient prognosis at 28 days.

Objective To investigate the syndrome differentiation characteristics of children with atopic dermatitis(AD)and the immune imbalance status in children with different syndrome types of AD.Methods A total of 159 AD children and 100 normal control children were enrolled.The peripheral blood eosinophil(Eo)count was measured by impedance method,total serum immunoglobulin E(IgE)by immunoturbidimetric assay,and interferon-gamma(IFN-γ),interleukin-4(IL-4),interleukin-5(IL-5)and interleukin-17(IL-17)were measured by multiple microspheres flow immunofluorescence assay.Results Among 159 AD children,syndrome of heart-fire and spleen-deficiency was most commom,accounting for 38.4%,followed by syndrome of blood-deficiency and wind-dryness(22.0%),syndrome of heat accumulation in heart and spleen(20.1%)and syndrome of spleen-deficiency and dampness-accumulation(19.5%).Compared with normal control group,there was no significant difference in serum IFN-γ level among different syndrome types of AD.The levels of peripheral blood Eo,serum total IgE,IL-4 and IL-17 in AD with heart-fire and spleen-deficiency syndrome were significantly increased(P<0.05).The levels of peripheral blood Eo,IL-4,IL-5 and IL-17 in AD with blood-deficiency and wind-dryness syndrome were significantly increased(P<0.05).The levels of IL-4,IL-5 and IL-17 in AD with heat accumulation in heart and spleen syndrome were significantly increased(P<0.05).The levels of peripheral blood Eo and serum IL-4 in AD with spleen-deficiency and dampness-accumulation syndrome were significantly increased(P<0.05).Conclusion Heart-fire and spleen-deficiency syndrome is the most common type in children with AD,however,the main type under 3 years old is heat accumulation in heart and spleen syndrome.Th2/Th17 immune imbalance are the main pathogenesis in heart-fire and spleen-deficiency syndrome,blood-deficiency and wind-dryness syndrome and heat accumulation in heart and spleen syndrome,and Th2 immune imbalance is the main pathogenesis of spleen-deficiency and dampness-accumulation syndrome.
