Efficacy and safety of a Chinese medicine formula Diankuang Mengxing Decoction combined with antipsychotics in the treatment of schizophrenia: A meta-analysis of randomized controlled trials.

BACKGROUND: In patients with schizophrenia, Diankuang Mengxing Decoction with antipsychotics is one of the treatments for it. However, little information is available regarding the difference between the therapeutic effect of Diankuang Mengxing Decoction with antipsychotics and other treatments. Systematic evaluation is conducted to assess the efficacy and safety of Diankuang Mengxing Decoction and other antipsychotics, which are used to treat schizophrenia. METHODS: We performed a systematic review (PROSPERO ID: CRD42023414603). This entailed a computerized search of several research databases from their respective dates of establishment until April 11, 2023, which collected clinical randomized controlled trials of Diankuang Mengxing Decoction combined with antipsychotics. The databases that contributed to this study were PubMed, Web of Science, Embase, EBSCOhost, Cochrane, Scopus, and Google Scholar. Each publication was screened according to defined inclusion and exclusion criteria, and appropriate literature was extracted and evaluated for quality, for which meta-analysis was performed using RevMan 5.4. RESULTS: A literature review of 456 publications resulted in the inclusion of 18 randomized controlled trials with data collected from a total of 1636 patients. Meta-analytical results showed combination with risperidone, olanzapine, chlorpromazine, clozapine, ziprasidone, or aripiprazole increased the overall effectiveness of Diankuang Mengxing Decoction when treating schizophrenia (P < . 00001), among whom olanzapine demonstrated the greatest enhancement (Z = 3.65, odds ratio = 4.26, 95% CI: 1.96-9.28, P = .0003). The 4-week/30-day treatment (P = .0003) and a dosage of 400 mL/d of Diankuang Mengxing Decoction (P = .0004) were more effective. Also, there were widespread reductions to the Positive And Negative Syndrome Scale (PANSS) total scores, PANSS-positive symptom scores, PANSS-negative symptom scores, general psychopathology scores (P < .05 for all), as well as the incidence of adverse effects (Z = 2.79, odds ratio = 0.34, 95% CI: 0.16-0.73, P = .005) in patients with schizophrenia. CONCLUSION: The combination of Diankuang Mengxing Decoction with different antipsychotics can improve the overall prognosis of patients with schizophrenia; Diankuang Mengxing Decoction combined olanzapine, a dosage of 400 mL/d and a duration of 4 weeks/30 days being the best in this regard, by alleviating the symptoms and diminishing the disorder's adverse effects. To build on this work, more large-sample, multi-center, and high-quality clinical studies in the future would help to further validate our findings.

Harmony in Nature: Exploring the Multisensory Impact of Classical Gardens on Individuals' Well-Being.

Objectives: Chinese classical gardens, designated as a vital world cultural heritage, embody a lasting legacy transcending generation. Despite the cultural importance of these gardens, a notable research gap exists in deciphering the nuanced emotional and physiological responses triggered by individual elements within classical garden landscapes. Our research question aims to uncover the specific emotional and physiological impacts of key garden elements-plants, architecture, waterscape, and rockery-on visitors, with a particular focus on the Humble Administrator's Garden. These elements serve as the primary subjects for video capture at four sites. Study Design: A within-subject design experiment was used. Methods: Videos were recorded at these sites, encompassing visual, auditory, and tactile elements. Ninety-five participants watched these videos in an indoor setting. While viewing, we measured participants' physiological responses, including heart rate variability, skin conductance, and skin temperature, will be monitored alongside subjective assessments obtained through self-reported questionnaires such as the Emotional Perception Scale and State-Trait Anxiety Scale. Results: Findings suggest that while all landscape types evoke positive emotions, natural elements exert a more profound influence. Additionally, the Large Rockery emerges as a focal point, indicating enhanced emotional relaxation through auditory and tactile stimuli, particularly among younger individuals. Conclusions: This research contributes to the broader understanding of how classical gardens impact human emotions and well-being, offering insights that can inform future landscape design and promote mental health in diverse cultural contexts.

Composite scattering characteristics analysis of micro-ellipsoidal periodic structure optical surface and microdefects.

In order to adjust and detect micro-nano periodic structure optical surface accurately and efficiently, the problem of composite scattering between micro-ellipsoidal periodic structure optical surface and pore defects is studied use the multi-resolution time domain (MRTD) approach. A calculation model is established for the intensity distribution of composite scattering, which is modulated by the micro-ellipsoidal periodic structure optical surface and microdefects. Results are in good agreement with those obtained using CST Microwave Studio software and the finite-different time-domain (FDTD) approach, which demonstrates the effectiveness of the calculation model and method. By combining the field distribution of the micro-ellipsoidal periodic structure optical surface containing microdefects with the optical response at different wavelengths, it is necessary to study the influence of various parameters of the micro-ellipsoidal structure and microdefects on the optical system of metamaterials. The effects of the parameters such as roughness, structure of micro-ellipsoidal unit, defect sizes and buried depths on the composite scattering characteristics are analyzed numerically. The results provide technical support for the fields of functional surface design, ultrasensitive detection, scattering peak orientation and frequency selection.

Ethyl acetate fraction of Thesium chinense Turcz. alleviates chronic obstructive pulmonary disease through inhibition of ferroptosis mediated by activating Nrf2/SLC7A11/GPX4 axis.

ETHNOPHARMACOLOGICAL RELEVANCE: Thesium chinense Turcz., a traditional Chinese herbal medicine, displays good therapeutic efficiency against respiratory diseases (e.g. pneumonia, pharyngitis) in clinical applications, however, its effects on COPD and the mechanism of action are still unclear. AIM OF THE STUDY: This study aims to investigate the therapeutic effect of the ethyl acetate fraction of Thesium chinense Turcz. (TCEA) on COPD and reveal the underlying mechanism. MATERIALS AND METHODS: A cigarette smoke (CS)-induced mouse COPD model was established, and the efficacy of TCEA was evaluated using peripheral blood testing, HE and Masson staining, qRT-PCR and ELISA assays. TCEA was analyzed for chemical composition by LC-MS/MS and HPLC. Prediction of major signaling pathways and potential targets was performed by network pharmacology. The molecular mechanism of TCEA was explored by immunoblotting, immunofluorescence staining, flow cytometry, and ubiquitination assay. Finally, potential active small molecules in TCEA were identified by molecular virtual screening. RESULTS: TCEA treatment significantly inhibited the secretion of pro-inflammatory factors and attenuated pathological emphysema. The main chemical constituents of TCEA were identified as flavonoids by UPLC-MS/MS. Network pharmacology analysis enriched the Nrf2 signaling pathway closely related to oxidative stress. Our results suggested that TCEA inhibited ferroptosis by activating Nrf2/SLC7A11/GPX4 axis and inhibiting lipid metabolism-related proteins, ACSL4, ALOX5 and COX2 in vivo and in vitro. Noteworthily, the beneficial impact of TCEA on regulation of SLC7A11 and GPX4 vanished after silencing Nrf2. Moreover, Nrf2 ubiquitination was inhibited by TCEA treatment. Finally, several flavonoids modulating Nrf2 were identified by molecular virtual screening. CONCLUSIONS: TCEA significantly alleviated COPD progression by inhibiting ferroptosis primarily through activation of Nrf2/SLC7A11/GPX4 signaling. Flavonoids are the main active components that exert their effects. These findings shed light on the mechanism of action of TCEA and its potential active components, providing a feasible approach for the treatment of COPD.

[Niche and interspecific association of main woody plants in Cunninghamia lanceolata plantation community in Jianfengling, China]. / 尖峰岭杉木人工林群落主要木本植物的生态位和种间联结.

Studies on niche and interspecific association can reveal plant interspecific relationship in the community, and provide theoretical support for promoting the transformation and development of plantation to natural forest. Based on Cunninghamia lanceolata investigation data of permanent plots of plantation in Jianfengling area of Hainan Tropical Rainforest National Park, we analyzed niche and interspecific association of the top 20 woody species in the community according to their importance values. The results showed that there were 163 species of woody species belonging to 101 genera and 55 families in the C. lanceolata plantation community, with complex species composition. As a constructive species, C. lanceolata had the highest importance value and niche breadth, and thus was the absolute dominant species in the community. It had a large niche overlap and niche similarity with many other species, among which the highest was observed in Adinandra hainanensis. The average niche overlap and niche similarity of the community were 0.54 and 0.49, respectively. The change trends of those two niche indicators were basically the same, indicating that some species were similar in resource demands. The overall association of main woody species was significantly positive. The χ2 test, association coefficient, Pearson correlation coefficient, and Spearman rank correlation coefficient suggested that the amounts of pairs with positive association were more than that with negative ones. The proportion of significant association species pairs was relatively low, indicating that the community stability was strong, species could coexist stably, and most species did not form close ties. On the whole, C. lanceolata had inhibited the regeneration of original tree species, and A. hainanensis, Garcinia oblongifolia, and Heptapleurum heptaphyllum could be used in natural transformation and restoration of C. lanceolata plantation in the Hainan Tropical Rainforest National Park.

[Water and heat transfer characteristics in summer maize farmland and its response to environmental factors in the old course of Yellow River]. / é»„æ²³æ• é“åŒºå¤çŽ‰ç±³å†œç”°æ°´çƒ­ä¼ è¾“ç‰¹å¾åŠå¯¹çŽ¯å¢ƒå› å­çš„å“åº”.

Accurate assessment of material and energy exchange between land and atmosphere is essential for water resources management and sustainable development of agriculture. To understand the characteristics of energy distribution and the dynamic change process of water and heat fluxes within the maize farmland ecosystem in the old course of Yellow River and their response to meteorological factors, we utilized the eddy covariance measurements and the full-element automatic weather station to continuously observe energy fluxes and conventional meteorological elements of summer maize farmland in the old course of Yellow River during 2019-2020. We analyzed the variation of energy fluxes and the effects of environmental factors, such as temperature, precipitation, and wind speed. Additionally, we calculated the energy closure rate and the proportion of energy distribution during the growth stage. The results showed that the peaks of net radiation, sensible heat flux, and latent heat flux occurred between 11:00 and 14:00, and the peak of soil heat flux occurred between 14:00 and 15:00. In terms of energy distribution, energy consumption of summer maize farmland during the whole growth period was dominated by latent heat flux and sensible heat flux. Energy was mainly consumed by sensible heat flux at sowing-emergence stage, accounting for 37.1% of net radiation, respectively. Energy in the rest of growth stages was dominated by latent heat flux. The energy closure rate during the whole growth period was better, with a coefficient of determination of 0.83, and the closure rate was higher in day and lower at night. Precipitation affected latent heat flux and sensible heat flux, and latent heat flux was more sensitive to precipitation. The increase of latent heat flux after rainfall was lower in late growth stage than in early growth stage. During the whole growth period of summer maize, solar radiation was the most significant meteorological factor affecting both sensible heat flux and latent heat flux, followed by vapor pressure deficit. The contribution of temperature and vapor pressure deficit to latent heat flux was significantly higher than sensible heat flux, while the relative contribution of wind speed, relative humidity, and solar radiation to latent heat flux was lower than sensible heat flux. Leaf area index and fractional vegetation cover had a significant positive correlation with latent heat flux and a significant negative correlation with sensible heat flux. Our results could deepen the understanding of water and heat transfer law of summer maize farmland in the old course of Yellow River, providing a theoretical basis for efficient water use of crops.

Fabrication of edible nanocellulose chitosan bi-component film based on a novel "swell-permeate" approach.

The fabrication of multi-component film with colloidal particles could be inconvenient. A novel "swell-permeate" (SP) strategy was proposed to form homogeneous multi-component films. The SP strategy allows colloidal particles to fit into the polymer network by stretching the polymer chains assisted by water. We demonstrated the strategy by creating films with polysaccharide substrates as ß-cyclodextrin grafted chitosan (CS) with nanocellulose. The addition of nanocellulose significantly increased the mechanical properties and the barrier performance of the films. The size of nanocellulose particles in affecting mechanical properties was investigated by applying different length of cellulose nanocrystal (CNC), the longer of which, due to denser physical entanglements, showed a better increase to the film in the elastic modulus and tensile strength to 4.54-fold and 5.71-fold, respectively. The films were also loaded with ethyl-p-coumarate (EpCA) and had an enhanced performance in anti-microbial for Altenaria alternata, Salmonella typhi, and Escherichia coli. The anti-oxidative property was increased as well, and both effects were valid both in vitro and in ready-to-eat apples. The strategy provides a practical and convenient method for fabricating colloidal particle containing films, and the novel idea of "swell-permeate" is potentially regarded as a new solution to the challenge of ready-to-eat food quality maintenance.

Impact of C-Reactive Protein and Liver Frailty Index on Sarcopenia and Poor Outcome in Liver Transplant Patients.

BACKGROUND: Sarcopenia is a complication that occurs after liver transplantation (LT), and it is a poor prognostic factor. METHODS: A total of 23 healthy controls and 131 LT patients (18 - 76 weeks of age) were enrolled in the study. Pa-tients were grouped according to the North American Working Group on Sarcopenia in Liver Transplantation by performing pre- and post-transplant CT scans of the third lumbar (L3). The serum C-reactive protein (CRP) was analyzed and the liver frailty index (LFI) was assessed. Their associations with postoperative sarcopenia, skeletal muscle index (SMI), and poor outcomes were examined. RESULTS: Before LT, the serum CRP was increased in patients with LT, compared with the healthy subjects, and had the highest levels in patients with sarcopenia. There were seventy-nine patients with sarcopenia after LT, including 48 who had been diagnosed with sarcopenia preoperatively and 31 who had a new onset of sarcopenia after LT. There was a moderate-strength negative correlation between the preoperative and postoperative rates of change in CRP and L3 SMI. Patients assessed as frail preoperatively (LFI ≥ 4.5) were associated with postoperative sarcopenia, and 19 of the new postoperative sarcopenia cases occurred in patients assessed as frail preoperatively. The serum CRP levels and LFI were significantly higher in patients who experienced a prolonged hospitalization and early infections postoperatively than in patients without significant adverse events. CRP (post-LT) > 2.575 pg/mL (OR = 1.16, 95% CI: 1.06 - 2.39, p = 0.026) as well as frailty (OR = 1.36, 95% CI: 1.20 - 2.60, p = 0.001) were independent predictors of sarcopenia after LT in patients. CONCLUSIONS: Serum CRP levels and LFI may be effective for an early detection of sarcopenia in patients with LT.

[Risk Factors and a Prediction Model for Frequent Acute Exacerbations of Chronic Obstructive Pulmonary Disease].

Objective To identify the risk factors of patients with frequent acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and construct a prediction model based on the clinical data,providing a theoretical basis for the clinical prevention and treatment. Methods A total of 25 638 COPD patients admitted to the Department of Respiratory and Critical Care Medicine,the Third People's Hospital of Chengdu from January 1,2013 to May 1,2023 were selected.Among them,11 315 patients were included according to the inclusion and exclusion criteria,and their clinical characteristics were analyzed.Multivariate Logistic regression was carried out to identify the risk factors for frequent AECOPD.A nomogram model was utilized to quantify the risk of acute exacerbation,and the performance of the prediction model was assessed based on the area under the receiver operating characteristic (ROC) curve. Results In the patients with frequent AECOPD,male percentage (P<0.001),age (P<0.001),urban residence (P<0.001),smoking (P<0.001),length of stay (P<0.001),total cost (P<0.001),antibiotic cost (P<0.001),diabetes (P=0.003),respiratory failure (P<0.001),heart disease (P<0.001),application of systemic glucocorticoids (P<0.001),white blood cell count (P<0.001),neutrophil percentage (P<0.001),C-reactive protein (P<0.001),total cholesterol (P<0.001),and brain natriuretic peptide (BNP) (P<0.001) were all higher than those in the patients with infrequent AECOPD.Multivariate Logistic regression analysis revealed that age,urban residence,smoking,diabetes,heart disease,Pseudomonas aeruginosa infection,application of systemic glucocorticoids,antibiotics,respiratory failure,and elevated white blood cell count,total cholesterol,and BNP were independent risk factors for hospitalization due to frequent AECOPD.A nomogram model of hospitalization due to frequent AECOPD was constructed according to risk factors.The ROC curve was established to evaluate the performance of the model,which showed the area under the ROC curve of 0.899 (95%CI=0.892-0.905),the sensitivity of 85.30%,and the specificity of 79.80%. Conclusion Frequent AECOPD is associated with smoking,heart disease,application of systemic glucocorticoids,Pseudomonas aeruginosa infection,age,low body mass index,and elevated BNP.Predicting the risks of hospitalization due to frequent AECOPD by the established model can provide theoretical support for the treatment and risk factor management of the patients.

Female genital prolapse and risk of psychiatric disorders: A two-sample Mendelian randomization analysis.

BACKGROUND: There is a growing body of evidence suggests a strong link between female genital prolapse (FGP) and mental health. However, the causal relationship between FGP and psychological disorders remains unclear. OBJECTIVES: Bidirectional Mendelian Randomization (MR) analysis has been applied to investigate the potential impact of FGP on the risk of seven common psychiatric disorders. METHODS: The two-sample MR analysis was conducted using genetic instruments such as Inverse variance weighted (IVW), MR Egger, weighted median, simple mode, and weighted mode from the genome-wide association study (GWAS) summary data in European populations. In addition, the Cochrane's Q test, MR-Egger intercept test, MR pleiotropy residual sum and outliers (MR-PRESSO) test and leave-one-out analysis were employed to assess the sensitivity and heterogeneity. RESULTS: The MR results revealed that FGP exhibited a potential marginal protective effect on bipolar disorder (BD) (odds ratio(OR) = 0.92, 95%confidence interval (95%CI: 0.85-0.99, P = 0.03) as well as schizophrenia(OR = 0.91, 95%CI:0.85-0.98, P = 0.01). Nevertheless, there was no causal correlation between genetically predicted FGP and obsessive compulsive disorder (OCD) (OR = 0.98, 95%CI:0.80-1.20, P = 0.84),depression (broad) (OR = 1.00, 95%CI:0.99-1.01, P = 0.76), major depression(OR = 0.98, 95%CI:0.94-1.03, P = 0.43), anxiety disorders (OR = 1.00, 95%CI:0.94-1.07,P = 0.97) and post-traumatic stress disorder(PTSD) (OR = 1.18, 95%CI:0.88-1.57,P = 0.27),respectively. In addition, BD was found to have a potential significant influence on FGP in the inverse MR analysis (OR = 0.83, 95%CI:0.72-0.97, P = 0.02). No significant heterogeneity or horizontal pleiotropy detected, and the results were deemed stable based on sensitivity analysis and leave-one-out test . LIMITATIONS: There are shortcomings such as data limitations, population bias, potential pleiotropy, and stratified analysis. CONCLUSIONS: While there is potential causal relationship between FGP and BD or schizophrenia, it does not exhibit any correction with OCD, depression (broad), major depression, anxiety disorders and PTSD among European populations.

A bibliometric analysis on laparoscopic pelvic floor surgery from 1996-2022.

INTRODUCTION: Pelvic organ prolapse is a common condition in middle-aged and older women. Laparoscopic pelvic floor surgery is frequently researched as a treatment for this issue. However, the effectiveness of this procedure has only been the subject of a few studies. METHODS: To quantitatively evaluate and display the relevant literature from the Web of Science database, we set the publication period of the literature from 1996 to 2022 and used VOSviewer and CiteSpace for visual analysis. RESULTS: Laparoscopic pelvic floor surgery research has increased year-on-year, with 1003 publications identified from 63 countries and published in 210 journals. In the global ranking of studies, the United States was the leader (n = 306; 30.5 %), with the most published authors being Campagna, Giuseppe (n = 17) and Scambia, Giovanni (n = 17). The International urogynecology journal included the most significant articles (n = 173; 17.2 %). Keyword analysis suggests that complications, rectal prolapse, native tissue repair, and warranty may have become hotspots in recent years. CONCLUSIONS: This bibliometric study shows that the depth and breadth of research on pelvic floor laparoscopic surgery have expanded rapidly over the last twenty-five years and that laparoscopic surgery has been recognized by different scholars or countries as an essential modality for the treatment of pelvic floor organ prolapse.

Rnai-based functional analysis of bursicon genes related to cuticle pigmentation in a ladybird beetle.

In arthropods, the binding of a bursicon (encoded by burs and pburs) heterodimer or homodimer to a leucine-rich repeat-containing G protein coupled receptor LGR2 (encoded by rk) can activate many physiological processes, especially cuticle pigmentation during insect ecdysis. In the current paper, we intended to ascertain whether bursicon signaling mediates body coloration in the 28-spotted larger potato ladybird, Henosepilachna vigintioctomaculata, and if so, by which way bursicon signal governs the pigmentation. The high expression of Hvburs, Hvpburs and Hvrk occurred in the young larvae, pupae and adults, especially in the head and ventral nerve cord. RNA interference (RNAi) aided knockdown of Hvburs, Hvpburs or Hvrk in the prepupae caused similar phenotypic defects. The pigmentation of the resultant adults was affected, with significantly reduced dark areas on the sternums. Moreover, the accumulated mRNA levels of two sclerotin biosynthesis genes, aspartate 1-decarboxylase gene Hvadc and N-ß-alanyldopamine synthase gene Hvebony, were significantly increased in the Hvburs, Hvpburs or Hvrk RNAi beetles. Furthermore, depletion of either Hvadc or Hvebony could completely rescue the impaired coloration on the sternums of Hvpburs RNAi adult. Our results supported that bursicon heterodimer-mediated signal regulate cuticle pigmentation. The bursicon signaling may tune the ratio of melanins (dark/black, brown) to sclerotins (light yellow, colorless) exerting its regulative role in the pigmentation of H. vigintioctomaculata sternums.

Guidance of development, validation, and evaluation of algorithms for populating health status in observational studies of routinely collected data (DEVELOP-RCD).

BACKGROUND: In recent years, there has been a growing trend in the utilization of observational studies that make use of routinely collected healthcare data (RCD). These studies rely on algorithms to identify specific health conditions (e.g. diabetes or sepsis) for statistical analyses. However, there has been substantial variation in the algorithm development and validation, leading to frequently suboptimal performance and posing a significant threat to the validity of study findings. Unfortunately, these issues are often overlooked. METHODS: We systematically developed guidance for the development, validation, and evaluation of algorithms designed to identify health status (DEVELOP-RCD). Our initial efforts involved conducting both a narrative review and a systematic review of published studies on the concepts and methodological issues related to algorithm development, validation, and evaluation. Subsequently, we conducted an empirical study on an algorithm for identifying sepsis. Based on these findings, we formulated specific workflow and recommendations for algorithm development, validation, and evaluation within the guidance. Finally, the guidance underwent independent review by a panel of 20 external experts who then convened a consensus meeting to finalize it. RESULTS: A standardized workflow for algorithm development, validation, and evaluation was established. Guided by specific health status considerations, the workflow comprises four integrated steps: assessing an existing algorithm's suitability for the target health status; developing a new algorithm using recommended methods; validating the algorithm using prescribed performance measures; and evaluating the impact of the algorithm on study results. Additionally, 13 good practice recommendations were formulated with detailed explanations. Furthermore, a practical study on sepsis identification was included to demonstrate the application of this guidance. CONCLUSIONS: The establishment of guidance is intended to aid researchers and clinicians in the appropriate and accurate development and application of algorithms for identifying health status from RCD. This guidance has the potential to enhance the credibility of findings from observational studies involving RCD.

Establishment of a nomogram model for predicting therapy complications in patients with polycythemia and deep venous thrombosis.

BACKGROUND: Patients with deep venous thrombosis (DVT) residing at high altitudes can only rely on anticoagulation therapy, missing the optimal window for surgery or thrombolysis. Concurrently, under these conditions, patient outcomes can be easily complicated by high-altitude polycythemia (HAPC), which increases the difficulty of treatment and the risk of recurrent thrombosis. To prevent reaching this point, effective screening and targeted interventions are crucial. Thus, this study analyzes and provides a reference for the clinical prediction of thrombosis recurrence in patients with lower-extremity DVT combined with HAPC. AIM: To apply the nomogram model in the evaluation of complications in patients with HAPC and DVT who underwent anticoagulation therapy. METHODS: A total of 123 patients with HAPC complicated by lower-extremity DVT were followed up for 6-12 months and divided into recurrence and non-recurrence groups according to whether they experienced recurrence of lower-extremity DVT. Clinical data and laboratory indices were compared between the groups to determine the influencing factors of thrombosis recurrence in patients with lower-extremity DVT and HAPC. This study aimed to establish and verify the value of a nomogram model for predicting the risk of thrombus recurrence. RESULTS: Logistic regression analysis showed that age, immobilization during follow-up, medication compliance, compliance with wearing elastic stockings, and peripheral blood D-dimer and fibrin degradation product levels were indepen-dent risk factors for thrombosis recurrence in patients with HAPC complicated by DVT. A Hosmer-Lemeshow goodness-of-fit test demonstrated that the nomogram model established based on the results of multivariate logistic regression analysis was effective in predicting the risk of thrombosis recurrence in patients with lower-extremity DVT complicated by HAPC (χ 2 = 0.873; P > 0.05). The consistency index of the model was 0.802 (95%CI: 0.799-0.997), indicating its good accuracy and discrimination. CONCLUSION: The column chart model for the personalized prediction of thrombotic recurrence risk has good application value in predicting thrombotic recurrence in patients with lower-limb DVT combined with HAPC after discharge.

Study on the Effects of Pasture Fiber on Thermal Properties of Slag Bricks.

In the context of ecological sustainability, this study focuses on the effect of variables of pasture fibers on the thermal properties of slag bricks made from a green recyclable material. This experiment uses slag as the binder, sand as the aggregate, and pasture fiber as an additive. The experimental variables include the additive content ratio of the pasture fiber, the size of the pasture fiber, and the type of pasture fiber. Significance analysis of the experimental results of the thermal performance tests is carried out using Minitab 18.1.0 software, and the optimal ratios for the thermal performance of the composite samples are derived from the response optimizer and conformity analysis. The results of the experiment's test analysis using Minitab 18 software indicate that, with an increase in pasture fiber content, the thermal performance of the composite samples initially decreases before increasing. Additionally, the lower the thermal conductivity of the composite sample, the lower the apparent density and the higher the porosity. Incorporating pasture fibers into slag bricks, as revealed in this study, reduces the waste of pasture resources in pastoral areas and promotes the development of sustainable building materials with favorable thermal properties.

Design, synthesis, and antifungal activity of novel pyrazole carboxamide derivatives containing benzimidazole moiety as potential SDH inhibitors.

To address the urgent need for new antifungal agents, a collection of novel pyrazole carboxamide derivatives incorporating a benzimidazole group were innovatively designed, synthesized, and evaluated for their efficacy against fungal pathogens. The bioassay results revealed that the EC50 values for the compounds A7 (3-(difluoromethyl)-1-methyl-N-(1-propyl-1H-benzo[d]imidazol-2-yl)-1H-pyrazole-4-carboxamide) and B11 (N-(1-(4-chlorobenzyl)-1H-benzo[d]imidazol-2-yl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide) against B. cinerea were notably low to 0.79 µg/mL and 0.56 µg/mL, respectively, demonstrating the potency comparable to that of the control fungicide boscalid, which has an EC50 value of 0.60 µg/mL. Noteworthy is the fact that in vivo tests demonstrated that A7 and B11 showed superior protective effects on tomatoes and strawberries against B. cinerea infection when juxtaposed with the commercial fungicide carbendazim. The examination through scanning electron microscopy revealed that B11 notably alters the morphology of the fungal mycelium, inducing shrinkage and roughening of the hyphal surfaces. To elucidate the mechanism of action, the study on molecular docking and molecular dynamics simulations was conducted, which suggested that B11 effectively interacts with crucial amino acid residues within the active site of succinate dehydrogenase (SDH). This investigation contributes a novel perspective for the structural design and diversification of potential SDH inhibitors, offering a promising avenue for the development of antifungal therapeutics.

Application effectiveness of "Youxin-1" in genetic diversity and structure analysis of local chickens.

China's local chicken breeds are rich in resources, and have formed different germplasm characteristics in the process of long-term selection and evolution. Scientific assessment of population genetic diversity and identification of inter-breed genetic structure are of great value to the protection and innovative utilization of local chicken breed resource. In order to evaluate the application effectiveness of 23K SNP chip "Youxin-1" in the analysis of genetic diversity and genetic structure of local chickens, we used RADseq to identify genomic genetic variation of 21 local chicken breeds and developed 23K chip "Youxin-1". The genetic statistics of each variety were calculated based on two sets of SNP data, and correlation, fitting and phylogenetic analysis were carried out to evaluate the application effectiveness of the chip. The results showed that the observed heterozygosity (Ho), polymorphism information content (PIC), inbred coefficient (FROH) and genetic differentiation coefficient (Fst) calculated based on the two SNP data sets were basically consistent in the 21 local chicken breeds. The genetic diversity of Langya chicken (LA), Piao chicken (PJ) and Wenchang chicken (WC) was relatively rich. The genetic diversity of Bian chickens (BJ), Langshan chickens (LS), Gushi chickens (GS), Dongxiang blue-eggshell chickens (DX) and Beijing fatty chickens (BY) was relatively poor, and the correlation coefficients of Ho, PIC, FROH and average Fst in the two groups were 0.794, 0.901, 0.926 and 0.984, respectively, all reaching extremely significant levels (P<0.01) with a high degree of fit (P<0.001) and R2 were 0.644, 0.827, 0.916 and 0.927. For the two sets of SNP data, the evolutionary tree constructed by neighbor-joining (NJ) method and maximum likelihood (ML) method was reasonable, and the 21 local chicken breeds were generally divided into six categories, which was consistent with the formation history and geographical distribution of the varieties. The 23K chip also realized reasonable clustering of the five new varieties without individual deviation. There are some differences in the estimation of genetic statistics using SNP with different densities, and data standardization is needed. 23K chip has good efficacy in the analysis of genetic diversity and structure of local chickens.

Veillonella parvula promotes root caries development through interactions with Streptococcus mutans and Candida albicans.

Root caries is a subtype of dental caries that predominantly impacts older adults. The occurrence and progression of root caries are associated with the homeostasis of dental plaque biofilm, and microbial synergistic and antagonistic interactions in the biofilm play a significant role in maintaining the oral microecological balance. The objective of the current study was to investigate the role of Veillonella parvula in the microbial interactions and the pathogenesis of root caries. The analysis of clinical samples from patients with/without root caries revealed that Veillonella and V. parvula were abundant in the saliva of patients with root caries. More importantly, a significantly increased colonization of V. parvula was observed in root carious lesions. Further in vitro biofilm and animal study showed that V. parvula colonization increased the abundance and virulence of Streptococcus mutans and Candida albicans, leading to the formation of a polymicrobial biofilm with enhanced anti-stress capacity and cariogenicity, consequently exacerbating the severity of carious lesions. Our results indicate the critical role of V. parvula infection in the occurrence of root caries, providing a new insight for the etiological investigation and prevention of root caries.
