Insights into the genetic variability and evolutionary dynamics of tomato spotted wilt orthotospovirus in China.

BACKGROUND: Viral diseases are posing threat to annual production and quality of tobacco in China. Recently, tomato spotted wilt orthotospovirus (TSWV) has been reported to infect three major crops including tobacco. Current study was aimed to investigate the population dynamics and molecular diversity of the TSWV. In the current study, to assess and identify the prevalence and evolutionary history of TSWV in tobacco crops in China, full-length genome sequences of TSWV isolates from tobacco, were identified and analyzed. METHODS: After trimming and validation, sequences of new isolates were submitted to GenBank. We identified the full-length genomes of ten TSWV isolates, infecting tobacco plants from various regions of China. Besides these, six isolates were partially sequenced. Phylogenetic analysis was performed to assess the relativeness of newly identified sequences and corresponding sequences from GenBank. Recombination and population dynamics analysis was performed using RDP4, RAT, and statistical estimation. Reassortment analysis was performed using MegaX software. RESULTS: Phylogenetic analysis of 41 newly identified sequences, depicted that the majority of the Chinese isolates have separate placement in the tree. RDP4 software predicted that RNA M of newly reported isolate YNKM-2 had a recombinant region spanning from 3111 to 3811 bp. The indication of parental sequences (YNKMXD and YNHHKY) from newly identified isolates, revealed the conservation of local TSWV population. Genetic diversity and population dynamics analysis also support the same trend. RNA M was highlighted to be more capable of mutating or evolving as revealed by data obtained from RDP4, RAT, population dynamics, and phylogenetic analyses. Reassortment analysis revealed that it might have happened in L segment of TSWV isolate YNKMXD (reported herein). CONCLUSION: Taken together, this is the first detailed study revealing the pattern of TWSV genetic diversity, and population dynamics helping to better understand the ability of this pathogen to drastically reduce the tobacco production in China. Also, this is a valuable addition to the existing worldwide profile of TSWV, especially in China, where a few studies related to TSWV have been reported including only one complete genome of this virus isolated from tobacco plants.

Artificial intelligence for detecting and delineating the extent of superficial esophageal squamous cell carcinoma and precancerous lesions under narrow-band imaging (with video).

BACKGROUND AND AIMS: Although narrow-band imaging (NBI) is a useful modality for detecting and delineating esophageal squamous cell carcinoma (ESCC), there is a risk of incorrectly determining the margins of some lesions even with NBI. This study aimed to develop an artificial intelligence (AI) system for detecting superficial ESCC and precancerous lesions and delineating the extent of lesions under NBI. METHODS: Nonmagnified NBI images from 4 hospitals were collected and annotated. Internal and external image test datasets were used to evaluate the detection and delineation performance of the system. The delineation performance of the system was compared with that of endoscopists. Furthermore, the system was directly integrated into the endoscopy equipment, and its real-time diagnostic capability was prospectively estimated. RESULTS: The system was trained and tested using 10,047 still images and 140 videos from 1112 patients and 1183 lesions. In the image testing, the accuracy of the system in detecting lesions in internal and external tests was 92.4% and 89.9%, respectively. The accuracy of the system in delineating extents in internal and external tests was 88.9% and 87.0%, respectively. The delineation performance of the system was superior to that of junior endoscopists and similar to that of senior endoscopists. In the prospective clinical evaluation, the system exhibited satisfactory performance, with an accuracy of 91.4% in detecting lesions and an accuracy of 85.9% in delineating extents. CONCLUSIONS: The proposed AI system could accurately detect superficial ESCC and precancerous lesions and delineate the extent of lesions under NBI.

Artificial intelligence-based assessments of colonoscopic withdrawal technique: a new method for measuring and enhancing the quality of fold examination.

BACKGROUND: This study aimed to develop an artificial intelligence (AI)-based system for measuring fold examination quality (FEQ) of colonoscopic withdrawal technique. We also examined the relationship between the system's evaluation of FEQ and FEQ scores from experts, and adenoma detection rate (ADR) and withdrawal time of colonoscopists, and evaluated the system's ability to improve FEQ during colonoscopy. METHODS: First, we developed an AI-based system for measuring FEQ. Next, 103 consecutive colonoscopies performed by 11 colonoscopists were collected for evaluation. Three experts graded FEQ of each colonoscopy, after which the recorded colonoscopies were evaluated by the system. We further assessed the system by correlating its evaluation of FEQ against expert scoring, historical ADR, and withdrawal time of each colonoscopist. We also conducted a prospective observational study to evaluate the system's performance in enhancing fold examination. RESULTS: The system's evaluations of FEQ of each endoscopist were significantly correlated with experts' scores (r = 0.871, P < 0.001), historical ADR (r = 0.852, P = 0.001), and withdrawal time (r = 0.727, P = 0.01). For colonoscopies performed by colonoscopists with previously low ADRs (< 25 %), AI assistance significantly improved the FEQ, evaluated by both the AI system (0.29 [interquartile range (IQR) 0.27-0.30] vs. 0.23 [0.17-0.26]) and experts (14.00 [14.00-15.00] vs. 11.67 [10.00-13.33]) (both P < 0.001). CONCLUSION: The system's evaluation of FEQ was strongly correlated with FEQ scores from experts, historical ADR, and withdrawal time of each colonoscopist. The system has the potential to enhance FEQ.

Inhibiting corrosion and side reactions of zinc metal anode by nano-CaSiO3coating towards high-performance aqueous zinc-ion batteries.

The aqueous Zn-ion batteries (AZIBs) have been deemed as one of the most promising energy storage devices owing to their high safety, low cost, and environmental benignity. Nevertheless, the severe corrosion of zinc metal anode and side reactions between the anode and electrolyte greatly hinder the practical application of AZIBs. To address above-mentioned issues, herein, a nano-CaSiO3layer was coated on the surface of Zn metal anode via the solution casting method. Results showed that this hydrophobic coating layer could effectively inhibit the direct contact of Zn metal anode with electrolyte, suppressing its corrosion and side reactions during Zn deposition/stripping. When applied in symmetrical cells, the nano-CaSiO3coated Zn (CSO-Zn) electrode exhibited much longer cycle life than bare Zn electrode. Moreover, with this nano-CaSiO3modified Zn anode, both vanadium-based and manganese-based full cells depicted excellent capacity retention. This nano-CaSiO3coating layer provides a good choice for improving the stability of Zn metal anode for high-performance AZIBs.

Artificial intelligence for diagnosing microvessels of precancerous lesions and superficial esophageal squamous cell carcinomas: a multicenter study.

BACKGROUND: Intrapapillary capillary loop (IPCL) is an important factor for predicting invasion depth of esophageal squamous cell carcinoma (ESCC). The invasion depth is closely related to the selection of treatment strategy. However, diagnosis of IPCLs is complicated and subject to interobserver variability. This study aimed to develop an artificial intelligence (AI) system to predict IPCLs subtypes of precancerous lesions and superficial ESCC. METHODS: Images of magnifying endoscopy with narrow band imaging from three hospitals were collected retrospectively. IPCLs subtypes were annotated on images by expert endoscopists according to Japanese Endoscopic Society classification. The performance of the AI system was evaluated using internal and external validation datasets (IVD and EVD) and compared with that of the 11 endoscopists. RESULTS: A total of 7094 images from 685 patients were used to train and validate the AI system. The combined accuracy of the AI system for diagnosing IPCLs subtypes in IVD and EVD was 91.3% and 89.8%, respectively. The AI system achieved better performance than endoscopists in predicting IPCLs subtypes and invasion depth. The ability of junior endoscopists to diagnose IPCLs subtypes (combined accuracy: 84.7% vs 78.2%, P < 0.0001) and invasion depth (combined accuracy: 74.4% vs 67.9%, P < 0.0001) were significantly improved with AI system assistance. Although there was no significant differences, the performance of senior endoscopists was slightly elevated. CONCLUSIONS: The proposed AI system could improve the diagnostic ability of endoscopists to predict IPCLs classification of precancerous lesions and superficial ESCC.

Csnk1a1 inhibition modulates the inflammatory secretome and enhances response to radiotherapy in glioma.

Glioblastoma multiforme (GBM), a fatal brain tumour with no available targeted therapies, has a poor prognosis. At present, radiotherapy is one of the main methods to treat glioma, but it leads to an obvious increase in inflammatory factors in the tumour microenvironment, especially IL-6 and CXCL1, which plays a role in tumour to resistance radiotherapy and tumorigenesis. Casein kinase 1 alpha 1 (CK1α) (encoded on chromosome 5q by Csnk1a1) is considered an attractive target for Tp53 wild-type acute myeloid leukaemia (AML) treatment. In this study, we evaluated the anti-tumour effect of Csnk1a1 suppression in GBM cells in vitro and in vivo. We found that down-regulation of Csnk1a1 or inhibition by D4476, a Csnk1a1 inhibitor, reduced GBM cell proliferation efficiently in both Tp53 wild-type and Tp53-mutant GBM cells. On the contrary, overexpression of Csnk1a1 promoted cell proliferation and colony formation. Csnk1a1 inhibition improved the sensitivity to radiotherapy. Furthermore, down-regulation of Csnk1a1 reduced the production and secretion of pro-inflammatory factors. In the preclinical GBM model, treatment with D4476 significantly inhibited the increase in pro-inflammatory factors caused by radiotherapy and improved radiotherapy sensitivity, thus inhibiting tumour growth and prolonging animal survival time. These results suggest targeting Csnk1a1 exert an anti-tumour role as an inhibitor of inflammatory factors, providing a new strategy for the treatment of glioma.

Clinical Evaluation a New Treatment for Infection After Ventriculoperitoneal Shunt.

ABSTRACT: To explore a new surgical treatment for infection and obstruction of ventriculoperitoneal shunt in hydrocephalus. Two cases of post-operative infection of ventriculoperitoneal shunt were analyzed retrospectively. One case was cryptococcal infection, the other case was Acinetobacter lwoffii. The number of cerebrospinal fluid cells was high, the infection of ventriculoperitoneal shunt was generally complicated with abdominal obstruction, and the hydrocephalus was aggravated again, The authors try to pull out the drainage tube at the end of abdominal cavity for external drainage, combined with intravenous antibiotics, completely control of infection, and then use the original shunt device for intraventricular jugular shunt. The authors explore that this method is simple, safe and effective, and it is an effective and feasible method for the treatment of infection after ventriculoperitoneal shunt.

Characteristics and treatments of ocular blast injury in Tianjin explosion in China.

BACKGROUND: To document characteristics and treatments of ocular blast injury from a fire and explosion. METHOD: Authors retrospectively evaluated 116 patients with 166 eye injuries from six hospitals. Terminology of ocular injury referred to Birmingham Eye Trauma Terminology, and best-corrected visual acuity (BCVA) was categorized with the ocular trauma score (OTS) grading system. Incidence, preoperational and follow-up BCVA, treatment of severe ocular blast injuries were surveyed. RESULTS: Oculoplastic injuries accounted for the majority of eye injuries, while globe injuries were presented in 52 eyes with median baseline OTS 70 ranging from 26 to 100. No endophthalmitis occurred. The mean timing of the first-stage operations was 9.4 ± 6.4 h after blast, while second-stage operations were performed on average 14.7 ± 0.9 days post blast. Final BCVA of 68.8% of eyes achieved 20/200 or better as followed, 7 open globe injuries had a BCVA of no light perception. Additionally, eyes presenting rupture, retinal detachment, vitreous hemorrhage, choroidal injury and initial BCVA less than 20/200 had worse final visual outcomes, while globe penetration was not associated with poor visual acuity. CONCLUSION: Various ocular injuries were commonly in the casualties of blast, in which open-globe injuries have worst visual prognosis. OTS is a valid approach for evaluation of prognosis and optimizing the therapeutic strategies subsequently in the massive casualty. Intense rescue and careful examination, proper surgery should be performed correctly to rescue patients.

Comparison of three digestive tract reconstruction methods for the treatment of Siewert II and III adenocarcinoma of esophagogastric junction: a prospective, randomized controlled study.

BACKGROUND: The incidence of adenocarcinoma of esophagogastric junction (AEG) has recently risen worldwide, including in Eastern Asia. The aim of the study was to explore the short-term and long-term clinical efficacy of piggyback jejunal interposition reconstruction single-tract reconstruction (PJIRSTR), piggyback jejunal interposition reconstruction double-tract reconstruction (PJIRDTR), and total gastrectomy esophageal jejunal Roux-en-Y anastomosis (TGRY) for the treatment of Siewert II and III AEG patients. METHODS: A total of 300 Siewert II and III AEG patients admitted to Shanxi Tumor Hospital from June 2015 to December 2017 were prospectively selected. Patients were randomly divided into PJIRSTR group (n = 98), PJIRDTR group (n = 103), and TGRY group (n = 99) using the random number table method. RESULTS: There were no statistically significant differences in total operation time, intraoperative blood loss, time of first anal exhaust, and postoperative hospital stay among the three groups (F = 2.526, 0.457, 0.234, 0.453; P > 0.05). The reconstruction time of PJIRSTR group and PJIRDTR group was longer than that of TGRY group (P < 0.01). There were no significant differences in cases of anastomotic leakage, anastomotic bleeding, abdominal infection, incision infection, ileus, and dumping syndrome in three groups (P > 0.05). The incidence of reflux esophagitis at 3, 6, 12, and 18 months after surgery in the PJIRSTR group and the PJIRDTR group were significantly lower than TGRY group in the same period (P < 0.05). Compared with PJIRDTR group and TGRY group, PJIRSTR group had a small fluctuation range of postoperative nutrition indexes and had basically recovered to the preoperative level at 18 months. Four patients of Visick grade IV presented in TGRY group 18 months postoperatively, which was significantly higher compared with the other two groups. CONCLUSION: Compared with PJIRDTR and TGRY, PJIRSTR can significantly reduce the incidence of postoperative reflux esophagitis and improve the long-term nutritional status of patients.

Identification of wheel track in the wheat field.

Agriculture machinery navigating along permanent traffic lanes in the farmland may avoid causing extensive soil compaction. However, the permanent traffic lanes are frequently covered up or eliminated by following tillage practices. It is necessary to identify the wheel tracks designed as permanent traffic lanes in order to ensure the agriculture machinery travels along the designated wheel tracks when cultivating the field. This study proposed an identification method of wheel tracks based on the morphological characteristics of wheel tracks and the environmental conditions around the wheel tracks in the wheat fields. The proposed method first utilized the maximum interclass variance to identify the contours of the main part of the wheel track and the shadow regions around the wheel track's edges. The main part of the wheel tracks was then separated from interference pixels by moving the centerline of the main part of the wheel track, which was derived by skeleton algorithm and curve fitting, towards the right or left edge of the wheel track at a specific distance. In a morphological opening operation, specific linear and circular structural elements were used to segment the shadow regions along the edge of the wheel track. The remaining wheel track was finally recognized by computing the complement of the region identified. After achieving the segmentation of wheel tracks, many reference points near the outside of the wheel track edge in the original image were chosen as fiducial points for evaluating the differences between the actual value and the recognized wheel track edge. The evaluation was based on computing the root mean squared error (RMSE) and the mean absolute error (MAE) of coordinates of reference points and recognized wheel track edge. The results showed that the largest RMSE and MAE were 24.01 pixels (0.0045 m) and 17.32 pixels (0.0032 m), respectively. The low values of RMSE and MAE reveal that the accuracy of the algorithm developed in this study is high, and using this algorithm may segment the wheel track in the wheat field accurately.

Comparison of asymmetric Z-plasty and Stallard Z-plasty in correction of epicanthus.

OBJECTIVE: To investigate the clinical effect of asymmetric Z-plasty with central axis inward displacement and stallard Z-plasty in the correction of epicanthus. METHODS: We retrospectively analyzed 193 patients who underwent epicanthal plasty in the Department of Plastic and Laser Cosmetology of Hunan Provincial People's Hospital from 2009 to 2019. The patients were divided into two groups according to different surgical methods: group A (n = 125) received the asymmetric Z-plasty with central axis inward displacement method and group B (n = 68) received the stallard Z-plasty method. The incidence of early postoperative complications, epicanthus retraction and scar concealment from 6 months after the operation were analyzed and evaluated. RESULTS: After 7 days postoperation, both group A and B of patients had grade A wound healing without any infection or poor wound healing. As for the retraction of the epicanthus, 97.6% of group A patients had no retraction and 2.7% had mild retraction, while 92.6% of group B patients had no retraction and 7.4% had mild retraction. The rank-sum test showed no statistically significant difference (p > 0.05) between the two groups. Regarding scar concealment, 35.2% of group A patients had partially hidden scars and 64.8% had completely hidden scars, while 72.1% of group B patients had no hidden scars and 27.9% had partially hidden scars, with a statistically significant difference (p < 0.05). CONCLUSION: Compared with stallard Z-plasty, asymmetric Z-plasty with central axis inward displacement has the advantages of concealed incision, easier scar concealment, less scar hyperplasia and stable effect, which results in higher postoperative satisfaction.

Effect of an artificial intelligence-assisted system on endoscopic diagnosis of superficial oesophageal squamous cell carcinoma and precancerous lesions: a multicentre, tandem, double-blind, randomised controlled trial.

BACKGROUND: Despite the usefulness of white light endoscopy (WLE) and non-magnified narrow-band imaging (NBI) for screening for superficial oesophageal squamous cell carcinoma and precancerous lesions, these lesions might be missed due to their subtle features and interpretation variations among endoscopists. Our team has developed an artificial intelligence (AI) system to detect superficial oesophageal squamous cell carcinoma and precancerous lesions using WLE and non-magnified NBI. We aimed to evaluate the auxiliary diagnostic performance of the AI system in a real clinical setting. METHODS: We did a multicentre, tandem, double-blind, randomised controlled trial at 12 hospitals in China. Eligible patients were aged 18 years or older and underwent sedated upper gastrointestinal endoscopy for screening, investigation of gastrointestinal symptoms, or surveillance. Patients were randomly assigned (1:1) to either the AI-first group or the routine-first group using a computerised random number generator. Patients, pathologists, and statistical analysts were masked to group assignment, whereas endoscopists and research assistants were not. The same endoscopist at each centre did tandem upper gastrointestinal endoscopy for each eligible patient on the same day. In the AI-first group, the endoscopist did the first examination with the assistance of the AI system and the second examination without it. In the routine-first group, the order of examinations was reversed. The primary outcome was the miss rate of superficial oesophageal squamous cell carcinoma and precancerous lesions, calculated on a per-lesion and per-patient basis. All analyses were done on a per-protocol basis. This trial is registered with the Chinese Clinical Trial Registry (ChiCTR2100052116) and is completed. FINDINGS: Between Oct 19, 2021, and June 8, 2022, 5934 patients were randomly assigned to the AI-first group and 5912 to the routine-first group, of whom 5865 and 5850 were eligible for analysis. Per-lesion miss rates were 1·7% (2/118; 95% CI 0·0-4·0) in the AI-first group versus 6·7% (6/90; 1·5-11·8) in the routine-first group (risk ratio 0·25, 95% CI 0·06-1·08; p=0·079). Per-patient miss rates were 1·9% (2/106; 0·0-4·5) in AI-first group versus 5·1% (4/79; 0·2-9·9) in the routine-first group (0·37, 0·08-1·71; p=0·40). Bleeding after biopsy of oesophageal lesions was observed in 13 (0·2%) patients in the AI-first group and 11 (0·2%) patients in the routine-first group. No serious adverse events were reported by patients in either group. INTERPRETATION: The observed effect of AI-assisted endoscopy on the per-lesion and per-patient miss rates of superficial oesophageal squamous cell carcinoma and precancerous lesions under WLE and non-magnified NBI was consistent with substantial benefit through to a neutral or small negative effect. The effectiveness and cost-benefit of this AI system in real-world clinical settings remain to be further assessed.

Evaluation of the AquaCrop model for simulating yield response of winter wheat to water on the southern Loess Plateau of China.

The objective of this study was to evaluate the performance of the FAO-AquaCrop model in winter wheat in the southern Loess Plateau of China. Multi-year field experimental data from 2004 and 2011 were used to calibrate and validate the model for simulating biomass, canopy cover (CC), soil water content, and grain yield under rainfed conditions. The model performance was evaluated using root mean square error (RMSE) and Willmott index of agreement (d) as criteria. The RMSE ranged from 0.16 to 0.38 t/ha for simulating aboveground biomass, 1.87 to 4.15% for CC, 0.50 to 1.44 t/ha for grain yield, and 5.70 to 22.56 mm for soil water content. The d ranged from 0.22 to 0.89, 0.25 to 0.43, 0.36 to 0.62 and 0.95 to 0.98 for aboveground biomass, CC, soil water content and grain yield, respectively. Generally, the model performed better for simulating CC and yield than biomass and soil water content. The results further indicated that AquaCrop is capable of simulating winter wheat yield under rainfed conditions. Further improvement may be needed to capture the variation of different management practices such as fertility and irrigation levels in this region.

Anxiety among College Students Who Self-Isolated During the Omicron Variant of SARS-CoV-2 in China.

We investigated the prevalence of anxiety and its associated risk factors among college students who self-isolated for 30 days during the emergence of the Omicron variant in China. We sampled college students specializing in four academic majors by cluster sampling and conducted questionnaires separately on days 1, 10, 20, and 30 after self-isolation. Anxiety was assessed using the 7-item Generalized Anxiety Disorder Scale (GAD-7) and Self-Rating Anxiety Scale (SAS). An odds ratio (OR) with a 95% confidence interval (CI) was used to estimate the strength of associations. A total of 10231 college students responded to the questionnaire 4 times. More students reported experiencing anxiety as the period of self-isolation approached 30 days. Among the students from four different major disciplines, medical students reported the highest rate of anxiety after 30 days of self-isolation, whereas humanities students exhibited the lowest rate of anxiety. Factor analysis indicated that the main reason for anxiety among all participating students was a delay in course completion. For engineering and medical students, there was an association between anxiety and research project delay. This study reveals the level of anxiety associated with COVID-19 pandemic-related self-isolation in college students and finds that it was aggravated by long-term isolation.

Association between skin disease and anxiety: a logistic analysis and prediction.

Background: Dermatosis has symptoms of flushing, itching, pain, and burning, which causes psychological distress in patients. Methods: We collected the data of 214 patients from the Wuhan Institute of Dermatology and Venereology from January 2020 to January 2022, including age, gender, diagnosis, Hamilton Anxiety Rating Scale (HAMA), and anxiety. First, descriptive analysis and difference analysis of the included data were carried out. Second, a correlation matrix was used to exclude the confounding factors with strong collinearity. Finally, logistic regression was used to analyze and predict the risk factors of anxiety. Results: In the anxiety group and nonanxiety group, eczema and generalized eczema accounted for the largest proportion, and there was no difference in the composition of the diagnosis between the 2 groups. Several related analyses proved the accuracy of the logistic model. The results showed that age had a protective effect on the anxiety of patients with skin diseases [odds ratio (OR) =0.8606 with 95% confidence interval (CI): 0.7812, 0.8987]. Neurodermatitis (OR =1.0853 with 95% CI: 1.0115, 1.2512), eczema (OR =1.1358 with 95% CI: 1.0215, 1.2129), generalized eczema (OR =1.3346 with 95% CI: 1.1212, 1.5521), and psoriasis (OR =1.3685 with 95% CI: 1.1728, 1.6215) were associated with the anxiety of patients. Prediction analysis showed that with increase of patients' age, the likelihood of anxiety decreased. Conclusions: This study demonstrated a strong correlation between skin diseases and anxiety and that the likelihood of anxiety decreases as age increases. Therefore, psychological intervention for patients with skin diseases, especially young patients, is essential.

Analysis of misdiagnosed or delayed-diagnosed Leprosy bacillus infection from 1990 to 2020 with a prophet time series prediction in Hubei Province, China.

To analyze the misdiagnosis or delayed diagnosis of leprosy in Hubei Province, China during the past 30 years, which can provide a scientific basis for improving the prevention and treatment of leprosy by proposing targeted intervention measures. A retrospective study was conducted to compile 161 cases of misdiagnosed or delayed diagnosis of leprosy in Hubei Province during 1990 to 2020 from the National Leprosy Prevention and Control Management Information System and the background information of regional leprosy control centers in Hubei Province. Among 161 study subjects, the shortest delay period was 25.30 months for cases aged 15 to 20 years, the longest delay period was 67.09 months for cases aged 51 to 60 years, the shortest delay period was 35.33 months for type TN cases, and the longest delay period was 75.17 months for type I cases. There were 71 cases (44.10%) misdiagnosed, and the top 5 misdiagnosed disease names were rash 23 cases (32.39%). Top 5 misdiagnosed cases were rash 23 (32.39%), rheumatism 10 (14.08%), skin ulceration 9 (12.68%), dermatitis 9 (12.68%), neuritis 9 (12.68%). In the prophet prediction, the overall trend of leprosy misdiagnosis was increasing and within 1 year the number is fluctuant. The training of medical personnel at all levels on leprosy prevention and treatment should be strengthened, and the public awareness of leprosy prevention and treatment should be enhanced.

Kaempferol prevents aseptic loosening via enhance the Wnt/ß-catenin signaling pathway in vitro and in vivo.

Kaempferol has demonstrated notable positive effects on the osteogenic differentiation of mesenchymal stem cells (MSC) and osteoblasts. A substantial body of research has emphasized the role of dislodged titanium particles in aseptic loosening following joint replacement surgery. This study predominantly investigates the suppressive influence of Kaempferol on osteolysis induced by titanium (Ti) alloy particles. In vitro investigations disclosed that Kaempferol effectively enhanced mineralization and alkaline phosphatase (ALP) activity in bone-marrow mesenchymal stem cells exposed to Ti particles. In addition, we conducted a comprehensive analysis of osteogenic differentiation microarray data_sets (GSE37676, GSE79814, and GSE114474) to identify differentially expressed genes. Significantly, Kaempferol upregulated the expression of critical osteogenic markers, including Runt-related transcription factor 2 (Runx2), osteocalcin (OCN), osterix/Sp-7, and ß-catenin. In vivo experiments, including H&E staining and Immunohistochemistry, provided compelling evidence that Kaempferol exerted a robust inhibitory effect on periprosthetic osteolysis in mice, with particularly pronounced results at higher doses. Moreover, it elevated the expression levels of osteogenic factors and Wnt/ß-catenin signaling components. These findings collectively indicate that Kaempferol mitigates the hindrance to osteogenesis posed by titanium particles by activating the Runx2 and Wnt/ß-catenin signaling pathways. This research lays a solid foundation for the prospective utilization of Kaempferol in the management of aseptic loosening following arthroplasty, offering promising therapeutic potential.

Interleukin-13 and its receptor are synaptic proteins involved in plasticity and neuroprotection.

Immune system molecules are expressed by neurons, yet their functions are often unknown. We have identified IL-13 and its receptor IL-13Ra1 as neuronal, synaptic proteins in mouse, rat, and human brains, whose engagement upregulates the phosphorylation of NMDAR and AMPAR subunits and, in turn, increases synaptic activity and CREB-mediated transcription. We demonstrate that increased IL-13 is a hallmark of traumatic brain injury (TBI) in male mice as well as in two distinct cohorts of human patients. We also provide evidence that IL-13 upregulation protects neurons from excitotoxic death. We show IL-13 upregulation occurring in several cohorts of human brain samples and in cerebrospinal fluid (CSF). Thus, IL-13 is a physiological modulator of synaptic physiology of neuronal origin, with implications for the establishment of synaptic plasticity and the survival of neurons under injury conditions. Furthermore, we suggest that the neuroprotection afforded through the upregulation of IL-13 represents an entry point for interventions in the pathophysiology of TBI.

Exploring the Employment Quality Evaluation Model of Application-Oriented University Graduates by Deep Learning.

In view of the employment difficulties of college graduates, this paper analyzes the overflow of graduates in a particular period caused by the expansion of enrollment in various colleges and universities and the social phenomenon of social positions in short supply. First, the employment status of application-oriented college students and the deficiencies of employment guidance courses are summarized. Then, deep learning technology is combined with the relevant employment concept to construct an employment training model to guide college students in employment. Besides, a questionnaire on learning effect and employment quality is designed from four perspectives: learning motivation, concentration, teaching process, and final results. The information collected through the questionnaire demonstrates that the employment quality and learning effect of male and female students are not significantly affected by gender differences. In addition, the P values of learning motivation, concentration, and teaching process are all less than 0.01, and the unstandardized coefficient of the teaching process is 0.349, which has the most significant impact on the learning effect. In short, the three factors positively affect the learning effect. Therefore, it comes to the conclusion of improving the ability and strategy of classroom employment guidance. If one wants to be successful in job hunting and career selection, it is not enough just to be competitive but also to be good at it. Being good at the competition is reflected in having good psychological quality, strength, and a good competitive state. In the job hunting and career selection competition, attention should be paid to whether the expected value is appropriate. College students should have sufficient self-awareness before preparing to submit resumes. During the interview, they should overcome emotional anxiety. If a person can treat study, work, and life in a good mood from beginning to end, he will win the competition. The research reported here can provide some reference suggestions for the employment quality of application-oriented college graduates.

Novel Combined Preparation and Investigation of Bergenin-Loaded Albumin Nanoparticles for the Treatment of Acute Lung Injury: In Vitro and In Vivo Evaluations.

A new method for targeting lung infections is of great interest using biodegradable nanoparticles. In this study, bergenin-loaded BSA NPs were developed against lung injury. Briefly, bergenin-loaded bovine serum albumin nanoparticles (BG@BSA NPs) were synthesized and characterized. HPLC recorded the major peak of bergenin. UV-Vis spectra had an absorbance at 376 nm. XRD revealed the presence of crystalline particles. FTIR confirmed the occurrence of functionalized molecules in the synthesized NPs. The particles were highly stable with a net negative charge of - 24.2. The morphology of NPs was determined by SEM and TEM. The mean particle size was 124.26 nm. The production of NO by NR8383 cells was decreased by BG@BSA NPs. Also, in mice, lipopolysaccharide-mediated acute lung inflammation was induced. BG@BSA NPs reduced macrophages and neutrophils in BALF and remarkably enhanced wet weight-to-dry weight (W/D) ratios and myeloperoxidase (MPO) activity. Further, BG@BSA NPs inhibited the production of inflammatory cells as well as tumor necrosis factor. The histopathological studies revealed that the damage and neutrophil infiltration were greatly inhibited by BG@BSA NPs. This indicates that BG@BSA NPs may be used to treat lung infections. Therefore, this study has given new insight into producing an active drug for the treatment of lung-associated diseases in the future.
