Autoimmune Rheumatic Diseases and Outcomes Following Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis.

Autoimmune Rheumatic Diseases (AIRDs) are associated with increased cardiovascular mortality. However, the post-percutaneous coronary intervention (PCI) outcomes in this population present a research gap, given the limited and discordant findings in existing studies. We conducted a systematic review and meta-analysis to assess the relationship between AIRDs and clinical outcomes after PCI; 9 studies with 7,027,270 patients (126,914 with AIRD, 6,900,356 without AIRD) were included. The AIRD cohort was characterized by an older age, a predominantly female demographic, and a greater prevalence of hypertension and diabetes mellitus. Over a mean follow-up period of 4.6 ± 3.5 years, AIRD patients demonstrated significantly higher odds of all-cause mortality (odds ratio (OR) 1.45, 95% CI: 1.25-1.78, P < .001) and major adverse cardiovascular events (MACE) (OR 1.63, 95% CI: 1.01-2.62, P = .04) compared with non-AIRD patients. Sensitivity analysis using adjusted estimates, confirmed the higher all-cause mortality (hazard ratio 1.32, 95% CI: 1.05-1.64, P = .01). Patients with rheumatoid arthritis had a significantly elevated odds of all-cause mortality (OR 1.50, 95% CI: 1.27-1.77) and MACE (OR 1.18, 95% CI: 1.14-1.21). Our study demonstrated an association between AIRDs and suboptimal long-term outcomes post-PCI. Prospective studies are warranted to explore the risk factors of unfavorable prognoses in patients with AIRDs.

Surface-enhanced Raman scattering spectroscopy monitoring and degradation of organic pollutants using a novel nanowire.

A multifunctional Ag/AlOOH nanowires (ANW) composite substrate was constructed, which not only accomplishes highly sensitive detection of organic dye molecules, but also has excellent performance in the degradation of pollutants. The ANW in the Ag/ANW substrate possesses a high aspect ratio, which extends the distribution area of Ag and enables a large number of hot spots on the active substrate. Additionally, due to the abundant OH groups on the ANW, there is an increased number of anchor sites for adsorbed metal ions in the Ag/ANW compound, thus contributing to the enhancement and degradation of molecules. Moreover, the constructed multifunctional Ag/ANW nanocomplexes also show great promise for practical applications, providing a reference for the detection and degradation of contaminants.

National Trends, Mortality and Outcomes in Intravascular Imaging-Guided Versus Angiography-Guided Percutaneous Coronary Intervention in the United States.

Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have become increasingly utilized in patients undergoing percutaneous coronary intervention (PCI). Despite these purported advantages, prior reports regarding the use of IVUS and OCT have indicated that contemporary use of intravascular imaging remains low with significant regional variation. Here, we present the findings of an updated contemporary analysis regarding the use of IVUS/OCT guided PCI vs. angiography-guided PCI in the United States. We also evaluated in-hospital mortality and clinical outcomes between IVUS/OCT-guided PCI versus angiography-guided PCI-only over million patients in the United States. There has been a significant decrease in the number of PCIs performed, while there has been increasing in trend of IVUS/OCT-guided PCI over this period. Most importantly, we found that IVUS/OCT guided PCI were associated with better clinical outcomes in terms of in-hospital mortality, compare with angiography guided PCI.

Initial Oxidation Behavior of AlCoCrFeNi High-Entropy Coating Produced by Atmospheric Plasma Spraying in the Range of 650 °C to 1000 °C.

As protective coatings for the thermal parts of aero-engines, AlCoCrFeNi coatings have good application prospects. In this study, atmospheric plasma spraying (APS) was used to prepare AlCoCrFeNi high-entropy coatings (HECs), which were oxidized from 650 °C to 1000 °C. The mechanism of the oxide layer formation and the internal phase transition were systematically investigated. The results show that a mixed oxide scale with a laminated structure was formed at the initial stage of oxidation. The redistribution of elements and phase transition occurred in the HECs' matrix; the BCC/B2 structure transformed to Al-Ni ordered B2 phase and Fe-Cr disordered A2 phase.

Prognostic Value of Neutrophil-to-Lymphocyte Ratio in Patients with Acute Decompensated Heart Failure: A Meta-Analysis.

Background: Inflammation plays a pivotal role in the pathogenesis of both acute and chronic heart failure. Recent studies showed that the neutrophil-to-lymphocyte ratio (NLR) could be related to adverse outcomes in patients with cardiovascular diseases. We sought to evaluate whether NLR could predict mortality in patients with acute heart failure by means of a meta-analysis. Methods: A comprehensive literature search was performed in PubMed, Embase, and Cochrane databases through January 2023 for studies evaluating the association of NLR with mortality in patients with acute heart failure. Primary outcomes were in-hospital mortality and long-term all-cause mortality. Endpoints were pooled using a random-effects DerSimonian-and-Laird model and were expressed as a hazard ratio (HR) or mean difference (MD) with their corresponding 95% confidence intervals. Results: A total of 15 studies with 15,995 patients with acute heart failure were included in the final study. Stratifying patients based on a cut-off NLR, we found that high NLR was associated with a significantly higher in-hospital mortality [HR 1.54, 95% CI (1.18-2.00), p < 0.001] and long-term all-cause mortality [HR 1.61, 95% CI (1.40-1.86), p < 0.001] compared to the low-NLR group. Comparing the highest against the lowest NLR quartile, it was shown that patients in the highest NLR quartile has a significantly heightened risk of long-term all-cause mortality [HR 1.77, 95% CI (1.38-2.26), p < 0.001] compared to that of lowest NLR quartile. However, the risks of in-hospital mortality were compared between both quartiles of patients [HR 1.78, 95% CI (0.91-3.47), p = 0.09]. Lastly, NLR values were significantly elevated among non-survivors compared to survivors during index hospitalization [MD 5.07, 95% CI (3.34-6.80), p < 0.001] and during the follow-up period [MD 1.06, 95% CI (0.54-1.57), p < 0.001]. Conclusions: Elevated NLR was associated with an increased risk of short- and long-term mortality and could be a useful tool or incorporated in the risk stratification in patients with acute heart failure.

Functional Oxidized Hyaluronic Acid Cross-Linked Decellularized Heart Valves for Improved Immunomodulation, Anti-Calcification, and Recellularization.

Tissue engineering heart valves (TEHVs) are expected to address the limitations of mechanical and bioprosthetic valves used in clinical practice. Decellularized heart valve (DHV) is an important scaffold of TEHVs due to its natural three-dimensional structure and bioactive extracellular matrix, but its mechanical properties and hemocompatibility are impaired. In this study, DHV is cross-linked with three different molecular weights of oxidized hyaluronic acid (OHA) by a Schiff base reaction and presented enhanced stability and hemocompatibility, which could be mediated by the molecular weight of OHA. Notably, DHV cross-linked with middle- and high-molecular-weight OHA could drive the macrophage polarization toward the M2 phenotype in vitro. Moreover, DHV cross-linked with middle-molecular-weight OHA scaffolds are further modified with RGD-PHSRN peptide (RPF-OHA/DHV) to block the residual aldehyde groups of the unreacted OHA. The results show that RPF-OHA/DHV not only exhibits anti-calcification properties, but also facilitates endothelial cell adhesion and proliferation in vitro. Furthermore, RPF-OHA/DHV shows excellent performance under an in vivo hemodynamic environment with favorable recellularization and immune regulation without calcification. The optimistic results demonstrate that OHA with different molecular weights has different cross-linking effects on DHV and that RPF-OHA/DHV scaffold with enhanced immune regulation, anti-calcification, and recellularization properties for clinical transformation.

Deep learning empowers photothermal microscopy with super-resolution capabilities.

In the past two decades, photothermal microscopy (PTM) has achieved sensitivity at the level of a single particle or molecule and has found applications in the fields of material science and biology. PTM is a far-field imaging method; its resolution is restricted by the diffraction limits. In our previous work, the modulated difference PTM (MDPTM) was proposed to improve the lateral resolution, but its resolution improvement was seriously constrained by information loss and artifacts. In this Letter, a deep learning approach of the cycle generative adversarial network (Cycle GAN) is employed for further improving the resolution of PTM, called DMDPTM. The point spread functions (PSFs) of both PTM and MDPTM are optimized and act as the second generator of Cycle GAN. Besides, the relationship between the sample's volume and the photothermal signal is utilized during dataset construction. The images of both PTM and MDPTM are utilized as the inputs of the Cycle GAN to incorporate more information. In the simulation, DMDPTM quantitatively distinguishes a distance of 60 nm between two nanoparticles (each with a diameter of 60 nm), demonstrating a 4.4-fold resolution enhancement over the conventional PTM. Experimentally, the super-resolution capability of DMDPTM is verified by restored images of Au nanoparticles, achieving the resolution of 114 nm. Finally, the DMDPTM is successfully employed for the imaging of carbon nanotubes. Therefore, the DMDPTM will serve as a powerful tool to improve the lateral resolution of PTM.

Association between rheumatoid arthritis and atrial fibrillation: A systematic review and meta-analysis.

Rheumatoid arthritis (RA) is an autoimmune disorder with a varying range of organs involved leading to adverse outcomes. However, very little is known, with conflicting results about the association between RA and atrial fibrillation (AF). We aim to evaluate the association between RA and AF, and other clinical outcomes. We performed a systematic literature search using PubMed, Embase, and Scopus for relevant articles from inception until September 10, 2023. Primary clinical outcomes were AF. Secondary outcomes were acute coronary syndrome (ACS), stroke, and all-cause mortality (ACM). A total of 4 679 930 patients were included in the analysis, with 81 677 patients in the RA group and 4 493 993 patients in the nonrheumatoid arthritis (NRA) group. The mean age of the patients was 57.2 years. Pooled analysis of primary outcomes shows that RA groups of patients had a significantly higher risk of AF (odds ratios [OR], 1.53; 95% confidence interval [CI]: [1.16-2.03], p < .001) compared with NRA groups. Secondary Outcomes show that the RA group of patients had significantly higher odds of ACS (OR, 1.39; 95% CI: [1.26-1.52], p < .001), and ACM (OR, 1.19; 95% CI: [1.03-1.37], p = .02) compared with the NRA groups. However, the likelihood of stroke (OR, 1.02; 95% CI: [0.94-1.11], p = .61) was comparable between both groups of patients. Our study shows that RA groups of patients are at increased risk of having AF, ACS, and ACM.

A novel practical method to predict anterior cruciate ligament hamstring graft size using preoperative MRI.

BACKGROUND: Predicting hamstring graft size preoperatively for anterior cruciate ligament (ACL) reconstruction is important for preempting an insufficient diameter in graft size intraoperatively, possibly leading to graft failure. While there are multiple published methods using magnetic resonance imaging (MRI) picture archiving and communication systems (PACS), most are not feasible and practical. Our study aims to (1) practically predict the ACL hamstring graft size in a numerically continuous manner using the preoperative MRI from any native MRI PACS system, (2) determine the degree of correlation between the predicted and actual graft size, and (3) determine the performance of our prediction method if we define an adequate actual graft size as ≥ 8 mm. METHODS: A retrospective review of 112 patients who underwent primary ACL reconstruction with quadrupled hamstring semitendinosus-gracilis grafts at a tertiary institution was conducted between January 2018 and December 2018. Graft diameter can be predicted in a numerically continuous manner as √[2*(AB + CD)], where A and B are the semitendinosus cross-sectional length and breath, respectively, and C and D are the gracilis cross-sectional length and breath, respectively. RESULTS: A moderately positive correlation exists between the predicted and actual graft diameter (r = 0.661 and p < .001). Our method yields a high specificity of 92.6% and a moderate sensitivity of 67.2% if we define an adequate actual graft size as ≥ 8 mm. An area under receiver-operating characteristic curve shows good discrimination (AUC = 0.856). CONCLUSIONS: We present a practical method to predict the ACL hamstring graft size with high specificity using preoperative MRI measurements.

Feedback regulation of the isoprenoid pathway by SsdTPS overexpression has the potential to enhance plant tolerance to drought stress.

In order to maintain the dynamic physiological balance, plants are compelled to adjust their energy metabolism and signal transduction to cope with the abiotic stresses caused by complex and changeable environments. The diterpenoid natural compound and secondary metabolites, sclareol, derived from Salvia sclarea, has gained significant attention owing to its economic value as a spice material and diverse physiological activities. Here, we focused on the roles and regulatory mechanisms of the sclareol diterpene synthase gene SsdTPS in the resistance of S. sclarea to abiotic stresses. Our results suggested that abiotic stresses could induce the response and upregulation of SsdTPS expression and isoprenoid pathway in S. sclarea. Ectopic expression of SsdTPS conferred drought tolerance in transgenic Arabidopsis, compared with wild-type. Overexpression of SsdTPS enhanced the transcription of ABA signal transduction synthetic regulators and induced the positive feedback upregulating key regulatory genes in the MEP pathway, thereby promoting the increase of ABA content and improving drought tolerance in transgenic plants. In addition, SsdTPS-overexpressed transgenic Arabidopsis improved the responses of stomatal regulatory genes and ROS scavenging enzyme activities and gene expression to drought stress. This promoted the stomatal closure and ROS reduction, thus enhancing water retention capacity and reducing oxidative stress damage. These findings unveil the potentially positive role of SsdTPS in orchestrating multiple regulatory mechanisms and maintaining homeostasis for improved abiotic stress resistance in S. sclarea, providing a novel insight into strategies for promoting drought resistance and cultivating highly tolerant plants.

Current Status and Family Factors Influencing Caries in the Deciduous Teeth of Children 3-6 Years of Age in Families Residing in Rural Heishanzui Township.

PURPOSE: To determine the caries status in children's deciduous teeth and examine the influence of family oral health behaviours on the caries status. MATERIALS AND METHODS: This cross-sectional study included 329 children aged 3-6 years in rural Heishanzui Township, Hebei Province, China, and used a completely random sampling method. These children underwent physical and oral health examinations. The questionnaires were given to the parents and caregivers of the examined children. RESULTS: The prevalence of caries in the deciduous dentition among children aged 3-6 years was 80.55%, with a dmft index of 4.93. Children in the caries group ate sweets, chocolates, and carbonated drinks more frequently than did children in the caries-free group (p < 0.05). Children in the caries-free group brushed their teeth more frequently, with parents helping their children brush, more often than did those in the caries-affected group (p < 0.05). The level of parental education and annual household income also had statistically significant effects on the prevalence of caries in the two groups (p < 0.05). Logistic regression analysis revealed that the frequency of eating sweets was a risk factor for caries in deciduous teeth (odds ratio = 2.20; p < 0.05). CONCLUSION: The prevalence of caries in deciduous teeth among children aged 3-6 years in rural Heishanzui Township was high. Compared to children in the caries-affected group, the families and children in the caries-free group had better oral hygiene behaviours. Moreover, the frequency of eating sweets was shown to be a risk factor for caries in deciduous teeth in children aged 3-6 years.

Integrated Transcriptome and Proteome Analysis Reveals the Regulatory Mechanism of Root Growth by Protein Disulfide Isomerase in Arabidopsis.

Protein disulfide isomerase (PDI, EC 5.3.4.1) is a thiol-disulfide oxidoreductase that plays a crucial role in catalyzing the oxidation and rearrangement of disulfides in substrate proteins. In plants, PDI is primarily involved in regulating seed germination and development, facilitating the oxidative folding of storage proteins in the endosperm, and also contributing to the formation of pollen. However, the role of PDI in root growth has not been previously studied. This research investigated the impact of PDI gene deficiency in plants by using 16F16 [2-(2-Chloroacetyl)-2,3,4,9-tetrahydro-1-methyl-1H-pyrido[3,4-b]indole-1-carboxylic acid methyl ester], a small-molecule inhibitor of PDI, to remove functional redundancy. The results showed that the growth of Arabidopsis roots was significantly inhibited when treated with 16F16. To further investigate the effects of 16F16 treatment, we conducted expression profiling of treated roots using RNA sequencing and a Tandem Mass Tag (TMT)-based quantitative proteomics approach at both the transcriptomic and proteomic levels. Our analysis revealed 994 differentially expressed genes (DEGs) at the transcript level, which were predominantly enriched in pathways associated with "phenylpropane biosynthesis", "plant hormone signal transduction", "plant-pathogen interaction" and "starch and sucrose metabolism" pathways. Additionally, we identified 120 differentially expressed proteins (DEPs) at the protein level. These proteins were mainly enriched in pathways such as "phenylpropanoid biosynthesis", "photosynthesis", "biosynthesis of various plant secondary metabolites", and "biosynthesis of secondary metabolites" pathways. The comprehensive transcriptome and proteome analyses revealed a regulatory network for root shortening in Arabidopsis seedlings under 16F16 treatment, mainly involving phenylpropane biosynthesis and plant hormone signal transduction pathways. This study enhances our understanding of the significant role of PDIs in Arabidopsis root growth and provides insights into the regulatory mechanisms of root shortening following 16F16 treatment.

Comprehensive Analysis of a Dendritic Cell Marker Genes Signature to Predict Prognosis and Immunotherapy Response in Lung Adenocarcinoma.

With the development of immune checkpoints inhibitors (ICIs), immunotherapy has recently taken center stage in cancer treatment. Dendritic cells exert complicated and important functions in antitumor immunity. This study aims to construct a novel dendritic cell marker gene signature (DCMGS) to predict the prognosis and immunotherapy response of lung adenocarcinoma (LUAD). DC marker genes in LUAD were identified by analysis of single-cell RNA sequencing data. 6 genes (G0S2, KLF4, ALDH2, IER3, TXN, CD69) were screened as the most prognosis-related genes for constructing DCMGS on a training cohort from TCGA data set. Patients were divided into high-risk and low-risk groups by DCMGS risk score based on overall survival time. Then, the predictive ability of the risk model was validated in 6 independent cohorts. DCMGS was verified to be an independent prognostic factor in multivariate analysis. Furthermore, we performed pathway enrichment analysis to explore possible biological mechanisms of the powerful predictive ability of DCMGS, and immune cell infiltration landscape and inflammatory activities were exhibited to reflect the immune profile. Notably, we bridged DCMGS with expression of immune checkpoints and TCR/BCR repertoire diversity that can inflect immunotherapy response. Finally, the predictive ability of DCMGS in immunotherapy response was also validated by 2 cohorts that had received immunotherapy. As a result, the patients with lower DCMGS risk scores showed a better prognosis and immunotherapy response. In conclusion, DCMGS was suggested to be a promising prognostic indicator for LUAD and a desirable predictor for immunotherapy response.

Association between Statin Use and Chemotherapy-Induced Cardiotoxicity: A Meta-Analysis.

Background: Chemotherapy-induced cardiac dysfunction (CIC) is a significant and concerning complication observed among cancer patients. Despite the demonstrated cardioprotective benefits of statins in various cardiovascular diseases, their effectiveness in mitigating CIC remains uncertain. Objective: This meta-analysis aims to comprehensively evaluate the potential cardioprotective role of statins in patients with CIC. Methods: A systematic literature search was conducted using PubMed, Embase, and Scopus databases to identify relevant articles published from inception until 10th May 2023. The outcomes were assessed using pooled odds ratio (OR) for categorical data and mean difference (MD) for continuous data, with corresponding 95% confidence intervals (95% CIs). Results: This meta-analysis comprised nine studies involving a total of 5532 patients, with 1904 in the statin group and 3628 in the non-statin group. The pooled analysis of primary outcome shows that patients who did not receive statin suffer a greater decline in the LVEF after chemotherapy compared to those who receive statin (MD, 3.55 (95% CI: 1.04-6.05), p = 0.01). Likewise, we observed a significantly higher final mean LVEF among chemotherapy patients with statin compared to the non-statin group of patients (MD, 2.08 (95% CI: 0.86-3.30), p > 0.001). Additionally, there was a lower risk of incident heart failure in the statin group compared to the non-statin group of patients (OR, 0.41 (95% CI: 0.27-0.62), p < 0.001). Lastly, the change in the mean difference for LVEDV was not statistically significant between the statin and non-statin groups (MD, 1.55 (95% CI: -5.22-8.33), p = 0.65). Conclusion: Among patients of CIC, statin use has shown cardioprotective benefits by improving left ventricular function and reducing the risk of heart failure.

Pathogenic role of super-enhancers as potential therapeutic targets in lung cancer.

Lung cancer is still one of the deadliest malignancies today, and most patients with advanced lung cancer pass away from disease progression that is uncontrollable by medications. Super-enhancers (SEs) are large clusters of enhancers in the genome's non-coding sequences that actively trigger transcription. Although SEs have just been identified over the past 10 years, their intricate structure and crucial role in determining cell identity and promoting tumorigenesis and progression are increasingly coming to light. Here, we review the structural composition of SEs, the auto-regulatory circuits, the control mechanisms of downstream genes and pathways, and the characterization of subgroups classified according to SEs in lung cancer. Additionally, we discuss the therapeutic targets, several small-molecule inhibitors, and available treatment options for SEs in lung cancer. Combination therapies have demonstrated considerable advantages in preclinical models, and we anticipate that these drugs will soon enter clinical studies and benefit patients.

Clinical Outcomes of Cardiogenic Shock due to Spontaneous Coronary Artery Dissection versus Cardiogenic Shock due to Coronary Artery Disease.

Spontaneous coronary artery dissection (SCAD) can be treated conservatively. However, some SCAD patients can develop cardiogenic shock (CS). We evaluated the outcomes of SCAD-related CS using data from a national population-based cohort study from January 1, 2016, to December 30, 2019. In our study of 32,640 patients with SCAD, about 10.6% of patients presented with cardiogenic shock. We found that SCAD patients with cardiogenic shock had higher mortality as well as greater complications including use of mechanical circulatory devices, arrythmias, respiratory support, and acute heart failure compared to those without cardiogenic shock. When comparing cardiogenic shock due to SCAD with that due to coronary artery disease (CAD), we found that while mortality rates were similar, those with cardiogenic shock due to SCAD were associated with higher risk of use of mechanical circulatory support, major bleeding, blood transfusion and respiratory failure.

UV communication cooperative formation UAV alliance capture algorithm.

The capture of target unmanned aerial vehicles (UAVs) by a UAV formation is one of the important and typical tasks in multi-UAV battlefield operations. In this paper, an ultraviolet (UV) light communication-assisted formation UAV alliance capture algorithm is proposed, which combines UV light communication technology with a capture algorithm. With the help of wireless UV light to assist UAV formation inter-UAV data confidentiality transmission and non-line-of-sight communication, the algorithm integrates the alliance generation algorithm with the region minimization strategy, solves the optimal alliance structure by using the dynamic programming method, and implements the aerial capture of the target UAVs by using the region minimization strategy, so as to complete the task of efficiently capturing multi-targets by the UAV formation in complex scenarios. Simulation comparisons were conducted between the region minimization strategy and the proposed UV communication-assisted formation UAV alliance capture algorithm. The results show that the proposed algorithm reduces energy consumption by 12.73% on average and decreases the average number of algorithm iterations by 27.49% during the UAV formation capture of multiple targets, which verifies its low energy consumption and high capture efficiency.

YTHDF1 mediates N-methyl-N-nitrosourea-induced gastric carcinogenesis by controlling HSPH1 translation.

YT521-B homology (YTH) domain family (YTHDF) proteins serve as readers that directly recognise m6A modifications. In this study, we aim to probe the role of YTHDF1 in environmental carcinogen-induced malignant transformation of gastric cells and gastric cancer (GC) carcinogenesis. We established a long-term low-dose MNU-induced malignant transformation model in gastric epithelial cells. In vivo and in vitro experiments were conducted to validate the malignant phenotype and characterise the roles of YTHDF1 and its downstream genes in malignant transformation cells. Additionally, we explored downstream m6A modification targets of YTHDF1 using RNA-sequencing, RNA immunoprecipitation, and proteomics analyses, and conducted validation experiments in cell experiments and clinical samples. Long-term low-dose exposure of MNU converted normal Gges-1 cells into malignant cells. YTHDF1 mRNA and protein expression are increased in MNU-induced malignant cells (p<0.001). Meanwhile, YTHDF1 knockdown inhibits the malignant potential of MNU-treated cells (p<0.01). YTHDF1 knockdown specifically suppresses HSPH1 protein, but not RNA levels. RIP-qPCR validates HSPH1 is the target of YTHDF1 (p<0.01). HSPH1 knockdown impairs the malignant potential of MNU-induced transformed cells. The increased expression of the key regulatory factor YTHDF1 in MNU-induced gastric carcinogenesis affects malignant transformation and tumorigenesis by regulating the translation of downstream HSPH1. These findings provide new potential targets for preventing and treating environmental chemical-induced gastric carcinogenesis.

The protective effects of BMSA1 and BMSA5-1-1 proteins against Babesia microti infection.

The intracellular parasite Babesia microti is among the most significant species causing human babesiosis and is an emerging threat to human health worldwide. Unravelling the pathogenic molecular mechanisms of babesiosis is crucial in developing new diagnostic and preventive methods. This study assessed how priming with B. microti surface antigen 1 (BHSA 1) and seroreactive antigen 5-1-1 (BHSA 5-1-1) mediate protection against B. microti infection. The results showed that 500 µg/ml rBMSA1 and rBMSA5-1-1 partially inhibited the invasion of B. microti in vitro by 42.0 ± 3.0%, and 48.0 ± 2.1%, respectively. Blood smears revealed that peak infection at 7 days post-infection (dpi) was 19.6%, 24.7%, and 46.7% in the rBMSA1, rBmSA5-1-1, compared to the control groups (healthy mice infected with B. microti only), respectively. Routine blood tests showed higher white blood cell, red blood cell counts, and haemoglobin levels in the 2 groups (BMSA1 and BMSA5 5-1-1) than in the infection control group at 0-28 dpi. Moreover, the 2 groups had higher serum interferon-γ, tumor necrosis factor-α and Interleukin-17A levels, and lower IL-10 levels than the infection control group throughout the study. These 2 potential vaccine candidate proteins partially inhibit in vitro and in vivo B. microti infection and enhance host immunological response against B. microti infection.

Early result of percutaneous full-endoscopic transforaminal lumbar interbody fusion in the treatment of single-level lumbar degenerative diseases: a retrospective study.

OBJECTIVE: The study aimed to evaluate the short-term clinical efficacy of percutaneous full-endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) for lumbar degenerative diseases (LDD). METHODS: From July 2020 to July 2021, 93 patients who underwent single-level lumbar fusion procedure were retrospective analysis. The patients were divided into Endo-TLIF group and transforaminal lumbar interbody fusion (TLIF) group. General demographic and perioperative data were recorded, the clinical outcomes were evaluated using visual analogue scale (VAS) and oswestry disability index (ODI). The disk height (DH) was compared between the two groups. RESULTS: All of the surgical procedures were successfully completed, and the patients were followed for a minimum of 2 years. Intraoperative blood loss, drainage volume, time to independent ambulation and hospital length of stay in the Endo-TLIF group were significantly decreased in comparison with the open TLIF group (p < 0.05). The VAS for back pain on postoperative 7 day and ODI on postoperative 1 month were lower in the Endo-TLIF group than in the open TLIF group (P < 0.05), but no significant difference at 1 year and 2 years postoperatively (P > 0.05). The VAS score of leg pain had no demographic statistically significant differences between the groups (P > 0.05). The DH were significantly heightened after surgery compared to the preoperative height (p < 0.05). CONCLUSION: Endo-TLIF is a minimally invasive, safety surgery which can achieve comparable short-term effects as open TLIF. It may be a promising option for the treatment of LDD.
