Effect of a multi-component exercise intervention on recovery of walking ability in stroke survivors: A Systematic Review with Meta-Analysis.

OBJECTIVE: To evaluate whether Multi-component exercise (MCE) is more effective than single exercise in improving walking ability in stroke patients. DESIGN: Systematic review and meta-analysis. DATA SOURCES: A systematic search of PubMed, Embase, Web of Science, Cochrane Library, and CINAHL from the establishment of each database to February 2024 was performed. A combination of medical subject headings and free-text terms relating to stroke, exercise were searched. STUDY SELECTION: Randomized controlled trials treating stroke survivors with multi-component exercise were included. The control groups received conventional treatments such as conventional treatment or no intervention or sham training; the experimental groups received multi-component exercise. The outcome measures were walking endurance, gait speed and balance ability. DATA EXTRACTION: The data extraction form was completed by two independent reviewers.The risk of bias was assessed using the Cochrane Risk of Bias tool for randomized Controlled Trials.Review Manager 5.4 software was used for data analysis.Subgroup analysis and sensitivity analysis were used to supplement the results with higher heterogeneity.The Preferred Reporting Project for Systematic Reviews and Meta-analyses 2020 guidelines were followed. DATA SYNTHESIS: 12 studies were included. Meta-analyses found that compared with the control group,MCE significantly affected gait speed (MD = 0.11; 95%CI 0.06, 0.16, I2 = 0%), but the effect on balance ability was not statistically significant.Subgroup analysis showed that MCE (≥60 min) was effective in improving walking endurance. These results suggest that multi-component exercise improves walking endurance and walking speed in stroke patients. CONCLUSION: Multi-component exercise helps improve the gait speed of stroke survivors. Prolonging the multi-component exercise time may have a better effect on improving the walking endurance of stroke patients.

Research on the relation between hydro-chemical and geological characteristics in karst area: Case study in Zhong Liang Mountain, Southwest China.

Karst groundwater, which is one of most important drinking water sources, is vulnerable to be polluted as its closed hydraulic relation with surface water. Thus, it is very important to identify the groundwater source to control groundwater pollution. The Pearson correlation coefficient among major ions (Na + K+, Ca2+, Mg2+, HCO3 -, SO4 2-, and Cl-) was employed to deduce the groundwater types in Zhong Liang Mountain, Southwest China. Then, the combined method of principal component analysis and cluster analysis were employed to identify the groundwater sources in a typical karst region of southwest China. The results shown that (1) the high positive correlation between cations and anions indicated the water-rock reaction of Ca-HCO3, Ca-SO4, (Na + K)-Cl, and Mg-SO4. (2) The major two principal components that would represent water-rock reaction of CaSO4 and Ca-HCO3 would, respectively, explain 60.41% and 31.80% of groundwater information. (3) Based on the two principal components, 33 groundwater samples were clustered into eight groups through hierarchical clustering, each group has similar water-rock reaction. The findings would be employed to forecast the surge water, that was an important work for tunnel construction and operation. PRACTITIONER POINTS: The components of groundwater was highly correlated with water-rock reaction. The principal component analysis screens the types of groundwater. The cluster analysis identifies the groundwater sources.

Plasticity in moth mating behavior and ejaculate proteomic diversity induced by male competition.

In male competition, large and costly ejaculates are advantageous. Prior research on male accessory gland secretions in Plutella xylostella left open questions about how males modulate their mating behaviors and ejaculate composition allocation in response to varying levels of competition. The current study aimed to delve deeper into these unexplored facets. A totally of 928 ejaculate proteins were identified across males exposed to different competition conditions. Notably, males courting under non-, low-, and high-competition scenarios exhibited 867, 635, and 858 ejaculate proteins, respectively. Approximately 10% of these ejaculate proteins displayed variations that aligned with changes in competition intensity. Subsequent analyses focused on the proteins transferred to females, revealing that 44% of ejaculate proteins were transferred, with 37 proteins exhibiting differential expression. Functional analyses uncovered their crucial roles in sperm maturation, motility, and capacitation. Our findings reveal adaptive adjustments in ejaculate protein abundance and transmission in P. xylostella as a response to varying competition levels. Moreover, fluorescent sperm labeling indicated higher sperm transfer during low competition correlated with shorter sperm length. Furthermore, evidence suggests that males shorten their courtship duration and extend their mating duration when faced with competition. These results illustrate how competition drives ejaculate investment and behavioral plasticity, offering valuable insights for advancements in assisted reproductive technologies and pest management strategies.

Risk assessment tool for anemia of chronic disease in systemic lupus erythematosus: a prediction model.

OBJECTIVE: This study aims to develop a predictive model for estimating the likelihood of anemia of chronic disease (ACD) in patients with systemic lupus erythematosus (SLE) and to elucidate the relationship between various factors and ACD METHODS: Individuals diagnosed with SLE for at least one year were enrolled and categorized into two groups: those with ACD and those without anemia symptoms. Patients were randomly assigned to training and test sets at an 8:2 ratio. The least absolute shrinkage and selection operator (LASSO) method was used to select predictors, followed by logistic regression for modeling. Model performance was assessed using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA) for both training and test sets. RESULTS: The study included a total of 216 patients, with 172 in the training set and 44 in the test set. LASSO identified 6 variables for constructing the predictive model, resulting in an area under the curve (AUC) of 0.833 (95% CI, 0.773-0.892) in the training set and 0.861 (95% CI, 0.750-0.972) in the test set. Calibration curves indicated consistency between expected and observed probabilities. DCA indicated that the model yielded a net benefit with threshold probabilities ranging from 20% to 90% in the training set and from 10% to 80% in the test set. CONCLUSION: This study presents a predictive model for assessing the risk of ACD in SLE patients. The model effectively captures the underlying mechanism of ACD in SLE and empowers clinicians to make well-informed treatment adjustments. Key Points • Development of a New Predictive Model: This study introduces a new predictive model to evaluate the likelihood of anemia of chronic disease (ACD) in patients with systemic lupus erythematosus (SLE). The model utilizes routine laboratory parameters to identify high-risk individuals, addressing a significant gap in current clinical practice. • Reflection of Potential Mechanisms for ACD Development: By incorporating the factors needed to construct the predictive model, this study also sheds light on the potential mechanisms of ACD development in SLE patients.

Biopolymer­carbonaceous composites, progress, and adsorptive mitigation of water pollutants.

Chitin is the second most abundant natural biopolymer, which is composed of N-acetyl glucosamine units linked by ß-(1 â†’ 4) Chitosan is an N-deacetylated product of chitin. Properties of chitosan and chitin, such as biocompatibility, non-toxic nature, and biodegradability, make them successful alternatives for energy and environmental applications. However, their low mechanical properties, small surface area, reduced thermal properties, and greater pore volume restrict the potential for adsorption applications. Multiple investigations have demonstrated that these flaws can be prevented by fabricating chitosan and chitin with carbon-based composites. This review presents a comprehensive analysis of the fabrication of chitosan/chitin carbon-based materials. Furthermore, this review examines the prevalent technologies of functionalizing chitosan/chitin biopolymers and applications of chitin and chitosan as well as chitosan/chitin carbon-based composites, in various environmental fields (mitigating diverse water contaminants and developing biosensors). Also, the subsequent regeneration and reuse of adsorbents were also discussed. Finally, we summarize a concise overview of the difficulties and potential opportunities associated with the utilization of chitosan/chitin carbon-based composites as adsorbents to remove water contaminants.

Safety and efficacy of minimal transcatheter aortic valve replacement: A systematic review and meta-analysis.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a preferred treatment for patients with highly critical aortic stenosis (AS), which is a difficult and complicated procedure, leaving a heavy economical burden on patients and national health insurance. Minimalist TAVR can simplify a part of the operation procedures, but the surgical efficacy and safety are still under debated. OBJECTIVES: Explore the effectiveness and safety of minimalist TAVR in the treatment of patients with aortic stenosis. METHODS: A systematic search of PubMed, Web of Science, and Embase databases was conducted for studies involving application of minimalist TAVR in patients with severe aortic stenosis, two researchers independently screened the literature, extracted data and Meta-analysis was performed using STATA 16.0 software. RESULTS: Nine studies, involving a total of 3,148 AS patients, were included. Minimalist TAVR has similar surgical success rates compared to standardized TAVR, intraoperative fluoroscopy time, dosage of contrast agent, and total operative time were superior to standard TAVR. Regarding surgical complications, the incidence of permanent pacemaker placement and moderate to severe paravalvular leakage were similar for both TAVR, the risk of major vascular complications and major bleeding events in the minimalist TAVR was significantly lower than the standard TAVR. The risk of overall death, stroke, and cardiovascular-related readmission within 30 days was similar in both procedures. CONCLUSION: Patients with severe aortic stenosis treated with minimalist TAVR have similar short-term efficacy as well as 30-day clinical outcomes to standard TAVR, while minimalist TAVR could reduce the risk of major vascular complications and bleeding complications.

Immunomodulation in allergic rhinitis: Insights from Th2 cells and NLRP3/IL-18 pathway.

Allergic rhinitis (AR) is characterized by nasal symptoms such as rubbing and sneezing, often triggered by allergen exposure. The purpose of this study is to dissect the roles of NLRP3-mediated immune modulation and macrophage pyroptosis in modulating T cell differentiation within the context of ovalbumin (OVA)-induced AR in mice. OVA-induced AR was established in mice, evaluating nasal symptoms, macrophage infiltration, cytokine levels, and T cell differentiation. Manipulations using NLRP3-/-, ASC-/- mice, clodronate liposome treatment, and NLRP3 inhibitor MCC950 were performed to assess their impact on AR symptoms and immune responses. Following OVA stimulation, increased nasal symptoms were observed in the OVA group along with augmented GATA3 expression and elevated IL-4 and IL-1b levels, indicative of Th2 polarization and cellular pyroptosis involvement. NLRP3-/- and ASC-/- mice exhibited reduced CD3+ T cells post OVA induction, implicating cellular pyroptosis in AR. Macrophage depletion led to decreased IgE levels, highlighting their involvement in allergic responses. Further investigations revealed enhanced macrophage pyroptosis, influencing Th1/Th2 differentiation in AR models. IL-18 released through NLRP3-mediated pyroptosis induced Th2 differentiation, distinct from IL-1b. Additionally, MCC950 effectively mitigated AR symptoms by modulating Th2 responses and reducing macrophage infiltration. This comprehensive study unravels the pivotal role of NLRP3-mediated immune modulation and macrophage pyroptosis in Th1/Th2 balance regulation in OVA-induced AR. Targeting NLRP3 pathways with MCC950 emerged as a promising strategy to alleviate AR symptoms, providing insights for potential therapeutic interventions in AR management.

Traffic accident duration prediction using multi-mode data and ensemble deep learning.

Predicting the duration of traffic accidents is a critical component of traffic management and emergency response on expressways. Traffic accident information is inherently multi-mode data in terms of data types. However, most existing studies focus on single-mode data, and the influence of multi-mode data on the prediction performances of models has been the subject of only very limited quantitative analysis. The present work addresses these issues by proposing a heterogeneous deep learning architecture employing multi-modal features to improve the accuracy of predictions for traffic accident durations on expressways. Firstly, six unique data modes are obtained based on the structured data and the text data. Secondly, a hybrid deep learning approach is applied to build classification models with reduced prediction error. Finally, a rigorous analysis of the influence for multi-mode data on the accident duration prediction performances is conducted using a variety of deep learning models. The proposed method is evaluated using survey data collected from an expressway monitoring system in Shaanxi Province, China. The experimental results show that Word2Vec-BiGRU-CNN is a suitable and better model using text features for traffic accident duration prediction, as the F1-score is 0.3648. This study confirms that the newly established structured features extracted from text data substantially enhance the prediction effects of deep learning algorithms. However, these new features were a detriment to the prediction effects of conventional machine learning algorithms. Accordingly, these results demonstrate that the processing and extraction of text features is a complex issue in the field of traffic accident duration prediction.

The impact of early in-hospital use of PCSK9 inhibitors on cardiovascular outcomes in acute coronary syndrome patients: A systematic review and meta-analysis.

OBJECTIVE: To explore the safety and assess the cardiovascular impact of early in-hospital administration of PCSK9 inhibitors in patients with acute coronary syndrome (ACS). METHODS: A systematic search of PubMed, Web of Science, and Embase databases was conducted for studies involving the use of PCSK9 inhibitors in ACS patients from inception to October 2023. Two independent researchers screened the literature, extracted data, and assessed the risk of bias in the included studies. Meta-analysis was performed using STATA 16.0 software. RESULTS: Nine studies, encompassing a total of 2896 ACS patients, were included in the analysis. When compared to statin monotherapy, early administration of PCSK9 inhibitors during hospitalization for ACS proved effective in reducing the incidence of major adverse cardiovascular events (MACEs). This encompassed a decrease in coronary revascularization [Relative Risk (RR) = 0.78, 95% CI (0.62, 0.98), P < 0.05], recurrent ACS [RR = 0.62, 95% CI (0.42, 0.94), P < 0.05], readmissions due to unstable angina [RR = 0.71, 95% CI (0.59, 0.85), P < 0.01], and strokes [RR = 0.31, 95% CI (0.09, 1.04), P = 0.058]. There was no significant difference in the incidence of death between the two groups.The use of PCSK9 inhibitors notably hastened the reduction of LDL-C, TG, and Non HDL-C levels in the short term. Additionally, it increased HDL-C levels and the number of individuals meeting LDL-C compliance criteria. Importantly, the risk of adverse drug events, such as ALT increase >3xULN, allergies, and musculoskeletal pain, did not significantly elevate with PCSK9 inhibitor use. CONCLUSION: The early administration of PCSK9 inhibitors has been found to safely and effectively lower diverse lipid levels in patients with ACS. This reduction is associated with a noteworthy decrease in MACEs, encompassing revascularization, recurrent ACS, and hospital readmissions.

(5R)-5-hydroxytriptolide ameliorates diabetic kidney damage by inhibiting macrophage infiltration and its cross-talk with renal resident cells.

OBJECTIVE: Diabetic nephropathy (DN) is the main cause of end-stage renal disease, and there are no targeted treatment options at present. The efficacy of the new immunosuppressive drug (5R)-5-hydroxytriptolide (LLDT8) in improving kidney inflammation has been demonstrated in multiple studies. The present study was intended to investigate the preventive and therapeutic effects of LLDT8 on DN and to reveal its potential pharmacological mechanisms. METHODS: The effects of LLDT8 on liver and kidney functions, and urine microprotein of Streptozotocin (STZ) induced DN mice were detected. The protective effect of LLDT8 on the kidney tissue was observed by pathological staining and transmission electron microscopy. Cell culture experiments were performed to detect the effects of LLDT8 on the expression of chemokines and epithelial-mesenchymal transition (EMT) in high glucose-induced TCMK1 cells using real-time polymerase chain reaction (RT-PCR) and western blot (WB) techniques and to detect the influence of LLDT8 on the secretion of pro-inflammatory and pro-fibrotic factors in high glucose-induced RAW264.7 cells. RESULTS: In animal experiments, treatment with high-dose LLDT8 (0.25 mg/kg/2d) reduced 24 h urinary albumin excretion, improved structural kidney damage, and delayed fibrosis progression in DN mice. Immunofluorescence results showed that LLDT8 intervention reduced macrophage infiltration in kidney tissues of DN mice. PCR and WB results of kidney tissues showed reduced expressions of chemokines CCL2 and M-CSF1 in the LLDT8 intervention group compared to the DN group. In cellular assays, LLDT8 treatment reduced chemokine secretion in high glucose-induced TCMK1 cells, but had no effect on EMT of TCMK1 cells. LLDT8 treatment reduced the secretion of pro-inflammatory and pro-fibrotic factors in high glucose-induced RAW264.7 cells. CONCLUSIONS: The present study suggests that LLDT8 could effectively inhibit the secretion of pro-inflammatory and pro-fibrotic factors by macrophages, which could alleviate high glucose-induced renal tissue injury and slow down the process of tissue fibrosis and DN.

Risk factors for delayed bleeding after intestinal polypectomy in children / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical characteristics and risk factors of delayed bleeding after intestinal polypectomy in children, and to provide a theoretical basis for clinical surgical intervention of intestinal polyps.@*METHODS@#A retrospective analysis was conducted on the clinical data of 2 456 children with intestinal polyps who underwent endoscopic high-frequency electrocoagulation loop resection in the Endoscopy Center of Children's Hospital Affiliated to Zhengzhou University from January 2014 to December 2021. According to the presence or absence of delayed bleeding after surgery, they were divided into bleeding group with 79 children and non-bleeding group with 2 377 children. A multivariate logistic regression analysis was used to investigate the risk factors for delayed bleeding. The receiver operating characteristic (ROC) curve was used to investigate the value of various indicators in predicting delayed bleeding.@*RESULTS@#Of all 2 456 children, 79 (3.22%) experienced delayed bleeding, among whom 5 children with severe delayed bleeding underwent emergency colonoscopy for hemostasis and 74 received conservative treatment, and successful hemostasis was achieved for all children. There were significant differences between the bleeding and non-bleeding groups in age, body mass index, constipation rate, location of lesion, time of endoscopic procedure, resection method (P<0.05). Children with a diameter of polyps of 6-10 mm and >20 mm were more likely to develop delayed bleeding after resection (P<0.05). The multivariate logistic regression analysis showed that endoscopic operation time, polyp diameter, and resection method were significantly associated with delayed bleeding (P<0.05). The ROC curve analysis showed that the endoscopic operation time, polyp diameter, and resection method had a good value in predicting delayed bleeding after intestinal polypectomy, with an area under the ROC curve of 0.706, 0.688, and 0.627, respectively.@*CONCLUSIONS@#Endoscopic high-frequency electrocoagulation loop resection has a lower incidence of delayed bleeding in children with intestinal polyps, and the endoscopic operation time, polyp diameter, and resection method are closely associated with the occurrence of postoperative delayed bleeding.

Reduced expression of semaphorin 3A in osteoclasts causes lymphatic expansion in a Gorham-Stout disease (GSD) mouse model / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Gorham-Stout disease (GSD) is a sporadic chronic disease characterized by progressive bone dissolution, absorption, and disappearance along with lymphatic vessel infiltration in bone-marrow cavities. Although the osteolytic mechanism of GSD has been widely studied, the cause of lymphatic hyperplasia in GSD is rarely investigated. In this study, by comparing the RNA expression profile of osteoclasts (OCs) with that of OC precursors (OCPs) by RNA sequencing, we identified a new factor, semaphorin 3A (Sema3A), which is an osteoprotective factor involved in the lymphatic expansion of GSD. Compared to OCPs, OCs enhanced the growth, migration, and tube formation of lymphatic endothelial cells (LECs), in which the expression of Sema3A is low compared to that in OCPs. In the presence of recombinant Sema3A, the growth, migration, and tube formation of LECs were inhibited, further confirming the inhibitory effect of Sema3A on LECs in vitro. Using an LEC-induced GSD mouse model, the effect of Sema3A was examined by injecting lentivirus-expressing Sema3A into the tibiae in vivo. We found that the overexpression of Sema3A in tibiae suppressed the expansion of LECs and alleviated bone loss, whereas the injection of lentivirus expressing Sema3A short hairpin RNA (shRNA) into the tibiae caused GSD-like phenotypes. Histological staining further demonstrated that OCs decreased and osteocalcin increased after Sema3A lentiviral treatment, compared with the control. Based on the above results, we propose that reduced Sema3A in OCs is one of the mechanisms contributing to the pathogeneses of GSD and that expressing Sema3A represents a new approach for the treatment of GSD.

A case-crossover study on the impact of air pollution on the number of pediatric respiratory outpatient and emergency visits in a hospital in Shanghai / 公共卫生与预防医学

Objective To investigate the correlation between the concentration of air pollutants (PM10, SO2, NO2) and the number of outpatient and emergency visits for pediatric respiratory diseases in a general hospital in Shanghai. Methods Data including pediatric respiratory disease outpatient and emergency visits in a hospital in Pudong New Area of Shanghai from May 1, 2013 to March 20, 2022 were collected. Daily concentration of air pollutants including PM10, SO2 and NO2 and meteorological data in Pudong New Area during the same period were collected. A case-crossover study with distributed lag non-linear model was conducted to explore the correlation between air pollutants (PM10, SO2, NO2) and the number of outpatient and emergency visits for pediatric respiratory diseases. Results The concentrations of PM10, SO2 and NO2 were positively with the number of outpatient and emergency visits for pediatric respiratory diseases. The strongest cumulative effect was observed on six days lag (Lag0-5) for PM10. For a 10 μg/m3 increase of the concentrations of PM10, the corresponding increase of cumulative pediatric respiratory disease outpatients was 1.10% (95%CI:0.97%, 1.23%) in Lag0-5. The strongest cumulative effect was observed on eight days lag (Lag0-7) for SO2 and NO2. For a 10 μg /m3 increase of the concentrations of SO2 and NO2, the corresponding increase of cumulative pediatric respiratory disease outpatients was 5.64% (95%CI:5.16%, 6.13%) and 5.41% (95%CI:5.15%, 5.66%) in Lag 0-7, respectively. The association of PM10 and SO2 with the number of pediatric respiratory disease visits in males was significantly stronger than that in females. The impact of PM10 on the number of pediatric respiratory disease visits in children aged 0-6 was higher than that in children aged 7-14, while the impact of SO2 and NO2 on the number of pediatric respiratory disease visits in children aged 7-14 was higher than that in children aged 0-6. Conclusion The concentration of ambient PM10, SO2, and NO2 is positively correlated with outpatient and emergency visits for pediatric respiratory diseases, with obvious lag and cumulative effect. Boys and children aged 0-6 are more susceptible to the hazard of air pollution.

Early predictors of refractory septic shock in neonates / 中国新生儿科杂志

Objective:To study the early predictors of refractory septic shock (RSS) in neonates.Methods:From July 2020 to December 2021, clinical data of neonates with septic shock admitted to the Neonatal Department of our hospital were retrospectively reviewed. According to the maximum septic shock score (SSS) during clinical course, the neonates were assigned into RSS group and non-RSS group. Perinatal data, laboratory results and hemodynamic parameters at diagnosis were compared between the two groups. Multiple logistic regression analysis was used to identify independent risk factors of RSS and septic shock-related death. Receiver operating characteristic (ROC) curve was constructed to evaluate the early predictors of poor prognosis.Results:A total of 130 neonates were enrolled, including 54 in RSS group and 76 in non-RSS group. Compared with the non-RSS group, the RSS group had significantly lower pH, base excess (BE), stroke volume index (SVI), cardiac output (CO) and cardiac index (CI).Meanwhile, the RSS group had significantly higher mean arterial pressure (MAP) to CI ratio (MAP/CI) and SSS [including bedside SSS (bSSS), computed SSS (cSSS) and modified version of cSSS (mcSSS)] (all P<0.05). Multiple logistic regression analysis showed that increased MAP/CI was an independent predictor of RSS. The cut-off value of MAP/CI was 11.6 [sensitivity 62%, specificity 87%, positive predictive value (PPV) 79% and negative predictive value (NPV) 77%], with an area under the curve (AUC) of 0.734. Increased mcSSS was an independent predictor of septic shock-related death. The cut-off value of mcSSS was 5.8 (sensitivity 83%, specificity 72%, PPV 21% and NPV 97%), with an AUC of 0.845. Conclusions:Increased MAP/CI (≥11.6) and mcSSS (≥5.8) may be early predictors of RSS and septic shock-related death in neonates.
