Objective:To investigate the relationship between oxygen consumption (VO 2), carbon dioxide production (VCO 2), and Oxygen Consumption/lactate (VO 2/Lac) with risk of death in patients with severe ARDS. Methods:A retrospective cohort study method was used, and the study subjects were hospitalized for >5 days adult patients with severe ARDS in the central intensive care unit of Henan Provincial People's Hospital from 1 March 2020 to 30 June 2023. The following patients were excluded: IC test was not completed on the 4th day of ICU admission, IC test results were unreliable, mechanical ventilation duration had exceeded 48 h at the time of ICU transfer or admission, palliative care patients and pregnant and parturient women. Using indirect calorimetry to determine VO 2 and VCO 2 values on the 4th day of admission, reviewing medical records to obtain general condition, disease information, blood gas analysis (including lactate value), diagnostic and therapeutic measures, and following up deaths by telephone and time of death. The primary outcome measure was death at 90 days, and the secondary outcome measure was death at 28 days, length of stay in ICU, total length of stay, and total hospitalization cost. Cox regression analysis and linear regression analysis were used to investigate the relationship between VO 2, VCO 2, VO 2/Lac and primary and secondary outcome indexes. Results:A total of 216 patients were enrolled, 78 patients (36.1%) died and 138 patients (63.9%) survived at 90 days. After correction for confounders, the results of multifactorial Cox regression analysis suggested that compared with the Q4 group, HR (95% CI) for 90-day risk of death in the VO 2 Q1 and Q2 groups was 3.21 (1.38, 7.49) and 3.24 (1.42, 7.38), and HR (95% CI) for 90-day risk of death in the VCO 2 Q1, Q2 and Q3 groups was 5.88 (2.33, 14.84), 4.26 (1. 60, 11.34) and 3.54 (1.34, 9.35), respectively, and the HR (95% CI) for 90-day risk of death in the VO 2/Lac Q1, Q2 and Q3 groups were 8.72 (3.01, 25.25), 8.43 (2.91, 24.47) and 4.04 (1.34, 12.17) respectively. P-trends were all <0.05, indicating that VO 2, VCO 2 and VO 2/Lac were linearly and negatively associated with the risk of 90-day mortality. In addition, VO 2, VCO 2, and VO 2/Lac were negatively associated with 28-day risk of death and higher VO 2/Lac was negatively associated with length of ICU stay. Conclusions:VO 2, VCO 2 and VO 2/Lac were negatively associated with 90-day mortality risk and 28-day mortality risk in patients with severe ARDS and may be independent risk factors predicting mortality risk of such patients.

Objective:To investigate the surgical efficacy of the modified areolar triangular dermal-glandular composite flap in correcting moderate to severe congenital nipple inversion.Methods:A retrospective analysis was performed on clinical data collected from patients with moderate to severe congenital nipple inversion treated at the Department of Plastic and Aesthetic Surgery, the First Affiliated Hospital of Hainan Medical University, between August 2018 and January 2023. Patients were divided into two groups based on the month of admission: the control group, treated with conventional areolar triangular flap, and the observation group, treated with the modified areolar triangular dermal-glandular composite flap. Postoperatively, nipple appearance, maintenance of nipple height, and incidence of complications were assessed in both groups. At six months after surgery, surgeons evaluated the therapeutic efficacy as good, fair, or poor; the total effective rate was calculated as (number of good + fair cases) / total number of cases ×100%. Patient satisfaction was rated as very satisfied, satisfied, fair, or dissatisfied; the satisfaction rate was calculated as (number of very satisfied + satisfied cases) / total number of cases ×100%. Nipple height (measured as the distance from the areolar plane to the apex of the nipple) was recorded before and after surgery. Measurement data were analyzed using the t-test, and categorical data were analyzed using the χ2 test. A P-value < 0.05 was considered statistically significant. Results:A total of 60 female patients (94 sides) were included in the study. In the control group (28 patients), the mean age was 28.5±5.2 years; 11 cases were unilateral, and 17 cases were bilateral; 22 sides were classified as moderate, and 23 sides as severe. In the observation group (32 patients), the mean age was 29.1±4.8 years; 15 cases were unilateral, and 17 cases were bilateral; 23 sides were moderate, and 26 sides were severe. There were no statistically significant differences between the two groups regarding age, severity of nipple inversion, or the ratio of unilateral to bilateral nipple inversion (all P>0.05). Postoperative follow-up lasted 6 to 15 months, with 28 patients (43 sides) in the observation group and 24 patients (39 sides) in the control group completing follow-up. No severe complications, such as nipple necrosis, occurred in either group, and nipple morphology and appearance were generally normal. The total effective rates based on surgeons' efficacy evaluations were 94.87% (37/39) in the control group and 100.00% (43/43) in the observation group, with no statistically significant difference ( P>0.05). Patient satisfaction rates were 76.92% (30/39) in the control group and 93.02% (40/43) in the observation group, showing a statistically significant difference ( P<0.05). There was no significant difference in preoperative nipple height between the two groups [-3.2±1.1 mm vs. -3.5±0.9 mm, P>0.05]. At 6 months post-surgery, nipple height in the observation group was significantly greater than in the control group [10.9±2.0 mm vs. 9.5±1.9 mm, P < 0.05]. Conclusion:The modified triangular dermal-glandular composite flap technique for correcting nipple inversion is relatively simple, demonstrates low long-term recurrence rates, and provides stable maintenance of nipple height. It is one of the preferred methods for treating moderate to severe congenital nipple inversion.

Objective:To investigate the curative effect and possible mechanism of rifaximin treatment on monocrotaline-induced hepatic sinusoidal obstruction syndrome (HSOS) in mice.Methods:Twenty-four male C57BL/6J mice were divided into three groups and treated with solvent control, monocrotaline, and rifaximin, respectively. The histopathological changes of the liver and intestine were observed by hematoxylin-eosin staining. The differences were compared in liver parameters, serum liver enzymes, inflammatory factors, apoptotic factors, gut microbiota, and gut tight junction proteins among three groups of mice. The inter-group comparison was conducted using a t-test and one-way analysis of variance.Results:The rifaximin-treated group had significantly improved liver histopathology. The serological levels of alanine aminotransferase and aspartate aminotransferase were (559.04±89.42) U/L and (676.90±106.25) U/L, respectively, which were significantly lower than those in the PA-HSOS model group [(846.05±148.46) U/L and (953.87±58.10) U/L, P<0.05], and were accompanied by lower levels of apoptotic cells and inflammatory factors. Additionally, the rifaximin-treated mice group gut microbiota had higher diversity compared with the PA-HSOS group ( P<0.05), and the Shannon index was 7.77±0.10 and 7.16±0.07, respectively, indicating apparent differences in microbiota among different groups. The abundance of Firmicutes in the rifaximin group was 39.58%±0.56%, which was significantly higher than that in the model group (24.25%±0.64%, P<0.05), while the abundance of Bacteroidetes was 54.7%±0.41%, which was significantly lower than that in the model group (70.92%±0.49%, P<0.05). Simultaneously, the expressions of gut tight junction proteins ZO-1 and Occludin showed an upward trend and validated transcription levels compared to the model group following rifaximin intervention ( P<0.05). Conclusion:Rifaximin can alleviate monocrotaline-induced hepatic sinusoidal obstruction syndrome in mice, and its mechanism may be via gut microbiota regulation, which in turn plays a role in improving intestinal barrier function.

Objective To provide a scientific basis for the quality control of Chrysanthemi Indici Flos medicinal materials and the sustainable development of this resource,the germplasm differences,tissue distribution,and developmental stage changes of flavonoid content in Chrysanthemum indicum was explored.Methods High-performance liquid chromatography(HPLC)was used to quantitatively analyze the five main flavonoid compounds,including linarin,tilianin,cynaroside,apigenin,and acacetin.Real-time fluorescence quantitative PCR(qPCR)technology was used to evaluate the relative expression levels of the rhamnosyltransferase(RhaT)gene at different developmental stages.Results The study found significant differences in flavonoid accumulation among different Chrysanthemum indicum germplasms,with the highest content of linarin observed in the Hubei diploid.Flavonoid content was significantly higher in leaves,flower buds,and flowers compared to stems and roots.Linarin and tilianin peaked at the flower bud stage and then gradually decreased,while the contents of apigenin and acacetin increased with flower development.The qPCR analysis further showed that the expression level of the RhaT gene was highly consistent with the accumulation pattern of linarin.Conclusion The results reveal that flavonoid content in Chrysanthemum indicum is significantly affected by germplasm,tissue type,and developmental stage,providing important data support for the quality evaluation of Chrysanthemum indicum medicinal materials and the rational development of this resource.

OBJECTIVE To investigate the impact of inflammatory cytokines related to different endotypes of chronic rhinosinusitis on the transcriptome of nasal epithelial cells.METHODS Human primary nasal epithelial cells were cultured in vitro,and treated with type 1,type 2,and type 3 inflammatory cytokines IFN-γ(10 ng/ml),IL-4(50 ng/ml),and IL-17A(50 ng/ml),respectively.After 48 hours,cells were collected for RNA extraction and transcriptome analysis.Differentially expressed genes were identified,followed by functional annotation and pathway enrichment analysis.Additionally,common regulated genes among different cytokines were analyzed.RESULTS Treatment of primary nasal epithelial cells with IFN-γ,IL-4,and IL-17A induced significant transcriptomic alterations,with 650,540,and 192 differentially expressed genes,respectively,compared to the control group.Functional annotation and pathway enrichment analysis showed that IFN-γ was mainly associated with defense response to virus,antigen processing and presentation,leukocyte and lymphocyte mediated immunity,and NOD-like receptor signaling pathway;IL-4 was mainly related to the regulation of leukocyte chemotaxis,cell-cell adhesion,ECM-receptor interaction,and MAPK signaling pathway;IL-17A was involved in the regulation of neutrophil chemotaxis,response to molecule of bacterial origin,chemokine signaling pathway,and NF-κB signaling pathway.Genes commonly regulated by IFN-γ,IL-4,and IL-17A were identified,with DUOX2 being upregulated by all the three cytokines.CONCLUSION IFN-γ,IL-4,and IL-17A reshapes the transcriptomic profile of nasal epithelial cells,which mainly regulates signaling pathways related to defense response to virus,leukocyte chemotaxis,and response to bacteria,respectively.
