Objective: To assess the association between the metabolic score for insulin resistance index (METS-IR) and overactive bladder (OAB) in the US population，so as to explore the potential of METS-IR as a predictive tool for OAB risk and to provide insights for early screening and intervention strategies. Methods: Based on the data from the National Health and Nutrition Examination Survey (NHANES) 2005-2018，a cross-sectional design was employed，and multivariate logistic regression models were used to analyze the association between METS-IR and OAB. METS-IR was analyzed both as a continuous variable and categorized into quartiles. To further validate the association between METS-IR and OAB across diverse populations，subgroup analyses were conducted in participants stratified by clinical characteristics. Smooth curve fitting was employed to test the linearity of the METS-IR-OAB relationship. Results: Elevated METS-IR was associated with an increased risk of OAB (P<0.001)，and this positive correlation remained stable when METS-IR was categorized into quartiles (P<0.001). Subgroup analyses revealed that the association between METS-IR and OAB was more pronounced in females，participants younger than 55 years，and non-diabetic individuals (P<0.05). Furthermore，smooth curve fitting confirmed a linear positive correlation between METS-IR and OAB，with this linear relationship observed in both diabetic and non-diabetic groups. Conclusion: This study，based on the NHANES 2005-2018 database，found a linear positive correlation between METS-IR and OAB.

BACKGROUND: The American Heart Association (AHA) introduced the concept of cardiovascular-kidney-metabolic (CKM) health and stage, reflecting the interaction among metabolism, chronic kidney disease (CKD), and the cardiovascular system. However, the association between CKM stage and the long-term risk of cardiovascular disease (CVD) has not been validated. This study aimed to evaluate the long-term CVD risk associated with CKM health metrics and CKM stage using data from a population-based cohort study. METHODS: In total, 5293 CVD-free participants were followed up to around 13 years in the Chinese Multi-provincial Cohort Study (CMCS). Considering the pathophysiologic progression of CKM health metrics abnormalities (comprising obesity, central adiposity, prediabetes, diabetes, hypertriglyceridemia, CKD, and metabolic syndrome), participants were divided into CKM stages 0, 1, and 2. The time-dependent Cox regression models were used to estimate the cardiovascular risk associated with CKM health metrics and stage. Additionally, broader CVD outcomes were examined, with a specific assessment of the impact of stage 3 in 2581 participants from the CMCS-Beijing subcohort. RESULTS: Among participants, 91.2% (4825/5293) had at least one abnormal CKM health metric, 8.8% (468/5293), 13.3% (704/5293), and 77.9% (4121/5293) were in CKM stages 0, 1, and 2, respectively; and 710 incident CVD cases occurred during a median follow-up time of 13.3 years (interquartile range: 12.1 to 13.6 years). Participants with each poor CKM health metric exhibited significantly higher CVD risk. Compared with stage 0, the hazard ratio (HR) (95% confidence interval [CI]) for CVD incidence was 1.31 (0.84-2.04) in stage 1 and 2.27 (1.57-3.28) in stage 2. Significant interactive impacts existed between CKM stage and age or sex, with higher CVD risk related to increased CKM stages in participants aged <60 years or females. CONCLUSION These findings highlight the contribution of CKM health metrics and CKM stage to the long-term risk of CVD, suggesting the importance of multi-component recognition and management of poor CKM health in CVD prevention.

OBJECTIVES: To investigate the active components and possible mechanisms of n-butanol fraction of Periploca forrestii Schltr. ethanol extract for treating Alzheimer's disease (AD). METHODS: The active components of n-butanol fraction of Periploca forrestii Schltr. ethanol extract were analyzed using UPLC-QE-MS technique. In a SD rat model of AD induced by treatment with AlCl₃ and D-gal, the therapeutic effects of low, moderate and high doses of the n-butanol fraction, saline, and donepezil hydrochloride were evaluated using ELISA, HE and Nissl staining, immunohistochemistry and Western blotting. The therapeutic mechanisms of the n-butanol fraction were explored using network pharmacology and molecular docking. RESULTS: Seventeen active components were identified from the n-butanol fraction of Periploca forrestii Schltr. ethanol extract, including phenylpropanoids, flavonoids, anthraquinones, triterpenoids, steroids, and volatile oils. In the rat models of AD, treatment with the n-butanol fraction significantly lowed AChE content in the hippocampus, increased the contents of ACh, SOD, CAT, and GSH-Px, enhanced the expressions of neuronal apoptotic factors Bcl-2, PI3K, Akt, p-PI3K, and p-Akt, and reduced the expressions of Bax and caspase-3 proteins. The treatment also dose-dependently up-regulated hippocampal expressions of Nrf-2, HO-1 and BDNF and down-regulated Keap-1, Aβ and Tau expressions. Bioinformatics analysis identified 14 key intersected targets (including TNF, AKT1 and ESR1) between the n-butanol fraction and AD. CONCLUSIONS The therapeutic effect of n-butanol fraction of Periploca forrestii Schltr. ethanol extract in AD mice is mediated by its multiple active components that regulate multiple targets and pathways.

Three soil conditioners were prepared from granulated food waste and decomposed cattle manure combined with desulfurization gypsum, coal gangue, and maifanite, respectively. Field trials were conducted in the saline field growing Cabernet Sauvignon. The effects of soil conditioners on rhizospheric bacterial communities were studied, with the aim of providing a scientific basis for soil amelioration and restoration. Five treatments were designed, including the control (T1), conventional fertilization (T2), reduced chemical fertilization+organic matter-based soil conditioner with calcium additives (T3), reduced chemical fertilization+organic matter-based soil conditioner with silica additives (T4), and reduced chemical fertilization+organic matter-based soil conditioner with magnesium additives (T5), each with three replications. The results indicated that soil conditioners improved the rhizospheric nutrients, yield, and quality of grape (P<0.05), increased relative abundance of Proteobacteria by 17.32%-23.37%, decreased relative abundance of unidentified_Bacteria and Acidobacteriota by 4.22%-28.42% and 20.88%-35.81%, respectively. The bacterial community composition and diversity were different between treatments. Function analysis showed that the expression levels of the genes involved in chromosome and protein synthesis, mRNA biosynthesis, and glyoxylate and dicarboxylate metabolism were up-regulated in the treatments with soil conditioners. The correlation analysis revealed that multiple environmental factors affected the alpha diversity of rhizospheric bacterial communities, and some bacterial taxa were closely related to the grape yield and quality. It is concluded that soil conditioners can effectively alter rhizosphere nutrient levels and bacterial community structures and functions. T5 treatment outperforms other treatments in improving the physico-chemical and biological characteristics of rhizosphere, and the yield, and quality of grape. It has potential for application, and provides an important basis for development of new-type soil conditioners.

Objective:To compare the therapeutic effects of modified plantar skin grafting and thigh skin grafting on the deep burn wounds of the back and buttocks.Methods:A retrospective cohort study was conducted to analyze the clinical data of 30 patients with deep burn wounds on their back and buttocks who were admitted to the 910th Hospital of Joint Logistic Support Force of PLA from January 2021 to April 2023, including 26 males and 4 females, aged 21-72 years [(49.9±14.0)years]. The total burn size was 50%-97% of the total body surface area (TBSA), with the third-degree burn on the back and buttocks 6%-16% TBSA. The burn wounds on the back and buttocks were repaired using plantar skin grafts alone, thigh skin grafts alone or plantar skin grafts combined with the grafts from other body parts. The patients were grouped according to the skin graft donor sites and the times of harvesting skin grafts: there were 20 patients undergone plantar skin grafting including 10 patient with plantar skin graft harvested once (group of plantar skin graft harvested once) and 10 patients with plantar skin graft harvested twice or three times (group of plantar skin graft harvested more than once), and 10 patients undergone thigh skin grafting harvested once (group of thigh skin graft harvested once). The areas of plantar skin grafts harvested at the last time and the wound areas on the back and butts that could be repaired each time were calculated. After the last harvest, the thickness of the stratum corneum, 7-day survival rate of the skin grafts, proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month Vancouver Scar Scale (VSS) scores of the donor sites in the group of plantar skin graft harvested once were compared with those in the group of thigh skin graft harvested once and the group of plantar skin graft harvested more than once. The appearance and texture of the skin graft, patients′ walking patterns and complications were observed at 6 months after the last skin harvest.Results:All the patients were followed up for 6-18 months [(7.8±1.6)months]. In the 20 patients with plantar skin grafts harvested, the areas of skin grafts harvested at the last time were 2.5%-4.5% TBSA [(3.4±0.6)% TBSA] and the wound areas that could be repaired each time were 3%-8% TBSA [(5.5±1.5)% TBSA]. After the last harvest, the thickness of the stratum corneum in the group of plantar skin graft harvested once was (190.4±8.9)μm, which was significantly thicker than that in the group of thigh skin graft harvested once [(50.0±6.6)μm] and that in the group of plantar skin graft harvested more than once [(166.8±21.9)μm] ( P<0.01); the 7-day survival rate of the skin grafts, proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month VSS scores of the donor sites were (93.6±2.3)%, 2.0 (0.1, 3.5)%, (9.9±1.8)days and (1.7±0.7)points in the group of plantar skin graft harvested once, (78.0±6.6)%, 5.3 (4.0, 5.8)%, (14.0±1.4)days and (4.9±2.3)points in the group of thigh skin graft harvested once, and (93.4±2.6) %, 2.0 (0.1, 3.8)%, (10.0±1.2)days and (1.8±0.8)points in the group of plantar skin graft harvested more than once. The group of plantar skin graft harvested once showed a significant increase in the 7-day survival rate and a significant decrease in the proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month VSS scores of the donor sites in comparison with the group of thigh skin graft harvested once ( P<0.05 or 0.01), while there were no significant differences in above mentioned indices between the group of plantar skin graft harvested once and the group of plantar skin graft harvested more than once ( P>0.05). At 6 months after the last skin harvest, the skin graft areas on the back and buttocks were flat, hard and firm and all the patients in the three groups could walk normally, with no complications such as severe itching, pain or folliculitis in the skin graft area. Conclusions:In the treatment of burn wounds on the back and buttocks, compared with thigh skin grafting, modified plantar skin grafting has advantages of thicker stratum corneum, better wear resistance and pressure resistance in the skin graft areas, a higher survival rate of skin grafts, rapid healing, mild scar, and undisturbed walking pattern after surgery and no common complications. Moreover, skin grafts can be harvested repeatedly from the donor sites, with no impact on the therapeutic effects.
