Abstract
Synaptic plasticity is crucial as it dynamically molds the strength and connectivity of neural circuits, influencing learning, memory, and the development of neurological disorders. Metformin, a widely prescribed anti-diabetic medication, has been shown to readily cross the blood-brain barrier (BBB) and the placenta. However, its prolonged impact on neuronal morphology and functions remains underexplored. In this study, we investigated the influence of metformin on dendrite development and synaptic plasticity in embryonic brains and primary rat cortical neurons. Our findings reveal a negative modulation of dendrite development by metformin, as evidenced by altered dendritic arborization, impaired dendritic spine morphology and disruptions in synaptic plasticity, suggesting a potential link between metformin exposure and aberrations in neuronal connectivity. In addition, we extend our insights to the impact of maternal metformin exposure on embryonic brains, revealing a significant inhibition of dendrite development in E18.5 rat brains. In conclusion, this study adds to the expanding knowledge base on the non-metabolic effects of metformin, emphasizing the significance of assessing its potential influence on both neuronal structure and function. There is an urgent need for further investigations into the enduring impact of prolonged metformin administration on the structural and functional aspects of neurons.

Abstract
Objective: To investigate the effects of human umbilical cord mesenchymal stem cell (hUCMSC) exosomes in the treatment of full-thickness skin defect wounds in mice through local wound application, subcutaneous injection at the wound margin, and tail vein injection, and to explore the optimal administration route of hUCMSC exosomes for wound treatment. Methods: This study was an experimental study. hUCMSC exosomes were extracted from the discarded umbilical cord tissue of three normal delivery women aged 25-35 years in the Department of Obstetrics and Gynecology of Baogang Hospital of Inner Mongolia and successfully identified. Totally 120 male BALB/c mice aged 6-8 weeks were selected, and full-thickness skin defect wounds were prepared on the back of them. According to the random number table, the injured mice were divided into control group (without drug administration), local wound application group, wound margin subcutaneous injection group, and tail vein injection group (with 30 mice in each group). Mice in the latter three groups were given 0.2 mL phosphate buffer solution containing 200 μg hUCMSC exosomes by local wound application, subcutaneous injection at the wound margin, and tail vein injection, respectively. On post injury day (PID) 7, 14, and 21, the general condition of the wound was observed, and the wound healing rate was calculated; the wound tissue was collected, the pathological changes and collagen fibers were observed respectively by hematoxylin-eosin staining and Masson staining, the number of new microvessels was observed by CD31 immunohistochemical staining, and the content of tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) was detected by enzyme-linked immunosorbent assay. The sample number was 10 in each group at each time point. Results: On PID 7, 14, and 21, the wounds of mice in the 4 groups all healed gradually, and the wound healing of the mice in wound margin subcutaneous injection group was the best; the wound healing rates of mice in the three administration groups were significantly higher than those in control group (P<0.05), the wound healing rates of mice in wound margin subcutaneous injection group and tail vein injection group were significantly higher than those in local wound application group (P<0.05), and the wound healing rates of mice in wound margin subcutaneous injection group were significantly higher than those in tail vein injection group (P<0.05). On PID 7, 14, and 21, the growth and epithelialization speed of the wound tissue of mice in the three administration groups were significantly accelerated, and the collagen fibers in the wounds of mice in the three administration groups were larger in number and more neatly arranged in comparison with the control group. On PID 7, 14, and 21, under every 200-fold visual field, the number of new microvessels in the wound tissue of mice in local wound application group was 24.1±2.5, 50.7±4.1, and 44.2±2.3, respectively, the number of new microvessels in the wound tissue of mice in wound margin subcutaneous injection group was 32.2±2.9, 67.5±4.9, and 53.6±3.7, respectively, and the number of new microvessels in the wound tissue of mice in tail vein injection group was 27.8±2.4, 59.1±3.7, and 49.6±2.6, respectively, which was significantly more than 20.6±1.7, 46.7±3.4, and 40.9±2.8 in control group (P<0.05); the number of new microvessels in the wound tissue of mice in wound margin subcutaneous injection group and tail vein injection group was significantly more than that in local wound application group (P<0.05); the number of new microvessels in the wound tissue of mice in wound margin subcutaneous injection group was significantly more than that in tail vein injection group (P<0.05). On PID 7, 14, and 21, the content of TNF-α and IL-6 in the wound tissue of mice in the three administration groups was significantly less than that in control group (P<0.05), the content of TNF-α and IL-6 in the wound tissue of mice in wound margin subcutaneous injection group and tail vein injection group was significantly less than that in local wound application group (P<0.05), and the content of TNF-α and IL-6 in the wound tissue of mice in wound margin subcutaneous injection group was significantly less than that in tail vein injection group (P<0.05). Conclusions: Local wound application, subcutaneous injection at the wound margin, and tail vein injection of hUCMSC exosomes can all promote the wound healing of full-thickness skin defects in mice through alleviating excessive inflammatory response and promoting angiogenesis. Among them, subcutaneous injection at the wound margin has a better therapeutic effect, indicating subcutaneous injection at the wound margin is the optimal administration route for hUCMSC exosomes in wound treatment.

Abstract
BACKGROUND CONTEXT Postoperative pain control following spine surgery can be difficult. The Enhanced Recovery After Surgery (ERAS) programs use multimodal approaches to manage postoperative pain. While an erector spinae plane block (ESPB) is commonly utilized, the ideal distance for injection from the incision, referred to as the ES (ESPB to mid-surgical level) distance, remains undetermined. PURPOSE We evaluated the impact of varying ES distances for ESPB on Numerical Rating Scale (NRS) measures of postoperative pain within the ERAS protocol. STUDY DESIGN/SETTING Retrospective observational study. PATIENT SAMPLE Adult patients who underwent elective lumbar spine fusion surgery. OUTCOME MEASURES Primary outcome measures include the comparative postoperative NRS scores across groups at immediate (T1), 24 (T2), 48 (T3), and 72 (T4) hours post-surgery. For secondary outcomes, a propensity matching analysis compared these outcomes between the ERAS and non-ERAS groups, with opioid-related recovery metrics also assessed. METHODS All included patients were assigned to one of three ERAS groups according to the ES distance: Group 1 (G1, ES > 3 segments), Group 2 (G2, ES = 2-3 segments), and Group 3 (G3, ES<2 segments). Each patient underwent a bilateral ultrasound-guided ESPB with 60 mL of diluted ropivacaine or bupivacaine. RESULTS Patients within the ERAS cohort reported mild pain (NRS < 3), with no significant NRS variation across G1 to G3 at any time. Sixty-five patients were matched across ERAS and non-ERAS groups. The ERAS group exhibited significantly lower NRS scores from T1 to T3 than the non-ERAS group. Total morphine consumption during hospitalization was 26.7 mg for ERAS and 41.5 mg for non-ERAS patients. The ERAS group resumed water and food intake sooner and had less postoperative nausea and vomiting. CONCLUSIONS ESPBs can be effectively administered at or near the mid-surgical level to the low thoracic region for lumbar spine surgeries. Given challenges with sonovisualization, a lumbar ESPB may be preferred to minimize the risk of inadvertent pleural injury.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on global health and economies, resulting in millions of infections and deaths. This retrospective cohort study aimed to investigate the effect of antifibrotic agents (nintedanib and pirfenidone) on 1-year mortality in COVID-19 patients with acute respiratory failure. METHODS Data from 61 healthcare organizations in the TriNetX database were analyzed. Adult patients with COVID-19 and acute respiratory failure were included. Patients with a pre-existing diagnosis of idiopathic pulmonary fibrosis before their COVID-19 diagnosis were excluded. The study population was divided into an antifibrotic group and a control group. Propensity score matching was used to compare outcomes, and hazard ratios (HR) for 1-year mortality were calculated. RESULTS The antifibrotic group exhibited a significantly lower 1-year mortality rate compared to the control group. The survival probability at the end of the study was 84.42% in the antifibrotic group and 69.87% in the control group. The Log-Rank test yielded a p-value of less than 0.001. The hazard ratio was 0.434 (95% CI: 0.264-0.712), indicating a significant reduction in 1-year mortality in the antifibrotic group. Subgroup analysis demonstrated significantly improved 1-year survival in patients receiving nintedanib treatment and during periods when the Wuhan strain was predominant. DISCUSSION This study is the first to demonstrate a survival benefit of antifibrotic agents in COVID-19 patients with acute respiratory failure. Further research and clinical trials are needed to confirm the efficacy of these antifibrotic agents in the context of COVID-19 and acute respiratory failure.

Abstract
Objective: To explore the effectiveness of minimally invasive surgical treatment for pancreatic acinar cell carcinoma (PACC). Methods: Six patients with PACC diagnosed in Peking University Third Hospital from January 2010 to September 2022 were retrospectively selected. Preoperative evaluation was performed on whether the lesions were eligible for surgery, including whether radical resection of liver metastases could be performed. Laparoscopic or Da Vinci robot-assisted resection was performed on six patients, and spleen retention was determined according to the original lesions and the relationship with peripheral blood vessels and tissues, while simultaneous resection was performed on cases of peripheral organ tissue invasion. The patients' basic information, preoperative general conditions, preoperative diagnosis and tumor stage, minimally invasive surgery methods, postoperative complications, pathological results, tumor stage and follow-up data were collected and analyzed to explore the effectiveness of minimally invasive surgery. Results: Among the six patients, four were males and two were females, with the age of 25-69 years. Five patients had abdominal pain and distension before surgery, five patients had tumors located at the tail of the pancreatic body, and one patient had tumors located at the head of the pancreas. Preoperative imaging (enhanced CT and MRI) was performed to measure the tumor diameter (2.8-10.0 cm). Tumor markers were elevated in two patients before surgery, and six patients underwent surgery through laparoscopy or robotic platform. No complications such as postoperative pancreatic fistula and bleeding were clinically relevant during and after surgery. There were two cases with concurrent or heterochronous liver metastasis, two cases with lymph node metastasis and nodular metastasis, four cases with tumor invasion of surrounding organs (stomach, spleen or duodenum), and three cases with vascular cancer thrombi. The follow-up time of the six patients was 12 to 165 months, and one patient underwent three operations due to postoperative liver metastasis and residual pancreatic recurrence, and the results were satisfactory. All the six patients survived at the last follow-up. Conclusions: PACC is prone to invade the surrounding organs, and has a large tumor diameter. Radical surgery for PACC can be completed through minimally invasive surgery, and satisfactory oncology prognosis can be obtained. In addition, some PACC patients with recurrence and metastasis can still be treated by surgery.

Abstract
While T-cell-mediated immune responses in solid tumors have been well-established and have driven major therapeutic advances, our understanding of B-cell biology in cancer is comparatively less developed. A total of 60 lung cancer patients were included, of which 53% were diagnosed at an early stage while 47% were diagnosed at an advanced stage. Flow cytometry was used to analyze the proportion of T and B cells in all blood samples, and the levels of human serum cytokines were also assessed. Compared to the control group, cancer patients showed lower frequencies of IgD+CD27+ marginal B cells and CD32+ B cells, and higher frequencies of T cells with lower CD8+ T cells and higher central memory and naïve CD4+ T cells. Additionally, advanced-stage cancer patients exhibited higher levels of cytokines, a higher proportion of effector memory CD8+ T cells, and a lower frequency of CD27+CD28+CD4+/CD8+ T cells. Linear regression analysis revealed significant correlations between cancer stage and the frequency of B and T cell subsets, leukocyte count, and cytokine levels. Survival analysis demonstrated that patients with higher frequency of class-switched B cells had a worse prognosis, while patients with higher frequency of CD8+ effector T cells and lower frequency of CD4+57+ T cells appeared to have a better survival rate. These findings provide valuable insight into the immunological changes that occur during lung cancer progression and have the potential to inform the development of new immunotherapeutic strategies.

Abstract
Different from classical autosomal recessive Wolfram syndrome, Wolfram-like syndrome is an autosomal dominant disorder caused by a heterozygous mutation in the WFS1 gene. In this case, a 7-year-old male child presented to the eye clinic due to vision loss that could not be corrected, discovered during a routine examination. The child had experienced hearing impairment since early childhood, leading to cochlear implantation. Ophthalmic examination revealed optic disc atrophy in both eyes. Optical coherence tomography imaging demonstrated a distinctive thickening of the outer plexiform layer with abnormal layering, characteristic of a single mutation in the WFS1 gene. Subsequent genetic testing identified a de novo heterozygous missense mutation c.2051C>T (p.A684V) in the WFS1 gene, which ultimately led to the diagnosis of Wolfram-like syndrome.

Abstract
The pathological classification and diagnostic criteria for lung neuroendocrine neoplasms (NENs) in the 2021 World Health Organization (WHO) lung tumor classification are similar to the prior classifications. However, the advances on the molecular studies of lung NENs have shown that both small cell lung carcinoma and large cell neuroendocrine carcinoma are highly heterogeneous tumors with neuroendocrine characteristics and can be subclassified based on the features of genomics or transcriptomics, which are valuable in the diagnosis of lung NENs subtypes and patient treatment. In addition, it is necessary to interpret emerging concepts such as "lung neuroendocrine tumor G3" and "histological transformation" from pathological perspectives, as well as to know the novel neuroendocrine biomarkers such as INSM1 and POU2F3. This article summarized the diagnostic changes and the advances of molecular pathology of lung NENs based on the latest WHO classification and molecular research.

Abstract
Patients with knee osteoarthritis (KOA) might have gait deviations, but few previous studies have discussed gait compensatory movements of the proximal and distal parts of muscle groups related to KOA. The study aimed to measure lumbar and hip movements during gait test and collect muscle activities of the lower extremities. Thirty-four participants with KOA and 28 healthy participants aged over 50 years were recruited for this study. Lumbar and hip motions during walking test were measured using inertial measurement units. Four muscle groups of the lower extremity (erector spinae, gluteus maximus, quadriceps muscle, and gastrocnemius) activities in gait were collected using surface EMGs. KOA patients used an 2.12∘anterior inclined lumbar spine (p = 0.007) and 22.94∘ flexed hip (p = 0.001) in gait compared to healthy participants. The KOA patients had a small hip movement range 30.19∘(p = 0.001) and a higher asymmetric stance time ratio 0.39 (p = 0.006). Patients with KOA showed decreased erector spinae and gluteus maximus muscle activation and increased activation of the quadriceps and gastrocnemius muscles during gait. In conclusion, patients with KOA used a hyperlordotic lumbar and hip flexed strategy, which overactivates distal extensor muscles through the whole gait and might cause overstress on the lower extremity joints.

Abstract
BACKGROUND/AIM Bladder cancer remains a significant global health concern, necessitating a deeper understanding of the molecular mechanisms underlying its progression. Cyclin-Dependent Kinase 5 (CDK5) has recently emerged as a potential player in bladder cancer pathogenesis. This study investigated the involvement of CDK5 in bladder cancer, emphasizing its potential as a therapeutic target. MATERIALS AND METHODS The expression levels of CDK5 and p35 (CDK5 regulatory protein) and their roles in the tumor grade and malignancy of patient samples were evaluated using western blot analysis and immunohistochemistry. In addition, tumor cancer genome atlas (TCGA) was utilized to evaluate survival rate in patients with bladder cancer. We further confirmed the role of CDK5 with in vitro experiments using western blot analysis, immunocytochemistry, cell culture-based proliferation and migration assays. RESULTS Higher CDK5 and p35 were associated with a higher tumor grade and poor survival rate in patients with bladder cancer. To confirm the role of CDK5 in vitro, we over-expressed CDK5 in bladder cancer cells. The results showed that the over-expression of CDK5 enhanced bladder cancer cell proliferation and migration. In addition, CDK5 inhibition by a pan-CDK inhibitor, Roscovitine (RV), significantly reduced proliferation of bladder cancer cells. Indeed, the migration and adhesion of bladder cancer cells were inhibited by RV treatment. CONCLUSION CDK5 might play important roles in bladder cancer progression and be a potential diagnostic and therapeutic target in the near future.

Abstract
AIM The purpose of this study was to evaluate the effectiveness of ECMO care board games facilitated teaching approach (ECMO care board games) in enhancing ECMO care knowledge, clinical reasoning and learning engagement among intensive care unit (ICU) nurses. BACKGROUND ECMO is a highly complex, relatively low-incidence, high-risk clinical life support device system used in the intensive care unit (ICU). Its usage has increased nearly tenfold over the past 30 years. Traditionally, ECMO education has been delivered through classroom teaching, which has demonstrated limited effectiveness in promoting nurses' learning engagement, clinical reasoning competency and confidence. The literature suggests that well-designed board games can enhance learning engagement, stimulate higher-level thinking and improve the effectiveness and confidence of nurses' learning. DESIGN A quasi-experimental study two-group repeated measure design. METHODS A purposive sample of 73 ICU nurses from two campuses of one medical center was recruited (37 in the experimental group and 36 in the control group). The experimental group received ECMO care training through ECMO care board games facilitated teaching approach, whereas the control group completed the training through a traditional teaching approach. Instruments used for data collection include a demographic information sheet, ECMO Care Knowledge Scale, Clinical Reasoning Scale (Huang et al., 2023) and Learning Engagement Scale (Ciou , 2020). Both groups completed a pre-test before the training, a post-test one week after the training and a second post-test three weeks after the training. RESULTS Prior to the intervention, there were no significant differences between the two groups in ECMO care knowledge and learning engagement. However, there was a significant difference in clinical reasoning. One week after the intervention, the experimental group demonstrated significantly higher scores in ECMO care knowledge, clinical reasoning and learning engagement than the control group (p <0.01). Three weeks after the intervention, the experimental group showed significantly higher scores in ECMO care knowledge, clinical reasoning and learning engagement (p <0.001). CONCLUSIONS The content for ECMO care is complex and difficult. Board games can enhance ECMO care knowledge, clinical reasoning and learning engagement. This teaching strategy may be applied to learning challenging subjects in the future to improve learning effectiveness. The clinical reasoning framework is conducive to guiding nurses' learning. In future continuing education, board games designed based on the clinical reasoning framework and tailored to the focus of in-service education can effectively enhance nurses' learning effectiveness.

Abstract
Response surface models (RSMs) are a new trend in modern anesthesia. RSMs have demonstrated significant applicability in the field of anesthesia. However, the comparative analysis between RSMs and logistic regression (LR) in different surgeries remains relatively limited in the current literature. We hypothesized that using a total intravenous anesthesia (TIVA) technique with the response surface model (RSM) and logistic regression (LR) would predict the emergence from anesthesia in patients undergoing video-assisted thoracotomy surgery (VATS). This study aimed to prove that LR, like the RSM, can be used to improve patient safety and achieve enhanced recovery after surgery (ERAS). This was a prospective, observational study with data reanalysis. Twenty-nine patients (American Society of Anesthesiologists (ASA) class II and III) who underwent VATS for elective pulmonary or mediastinal surgery under TIVA were enrolled. We monitored the emergence from anesthesia, and the precise time point of regained response (RR) was noted. The influence of varying concentrations was examined and incorporated into both the RSM and LR. The receiver operating characteristic (ROC) curve area for Greco and LR models was 0.979 (confidence interval: 0.987 to 0.990) and 0.989 (confidence interval: 0.989 to 0.990), respectively. The two models had no significant differences in predicting the probability of regaining response. In conclusion, the LR model was effective and can be applied to patients undergoing VATS or other procedures of similar modalities. Furthermore, the RSM is significantly more sophisticated and has an accuracy similar to that of the LR model; however, the LR model is more accessible. Therefore, the LR model is a simpler tool for predicting arousal in patients undergoing VATS under TIVA with Remifentanil and Propofol.

Abstract
Objective: To investigate the clinicopathological characteristics, diagnosis and differential diagnosis of intravascular large B-cell lymphoma (IVLBCL) and its collision tumors. Methods: Five cases of IVLBCL were collected, including 2 cases of collision tumors, and 1 case complicated with liver cirrhosis. The morphology and immunophenotype were analyzed. The related literature was reviewed. Results: There were 2 females and 3 males, aged from 53 to 73 years, with a median age of 65 years. The tumors were located in the lower extremities, right cerebellar hemisphere, left kidney, bilateral nasal cavity, and liver, respectively. Cases 2 and 3 were incidentally found in meningioma and renal cell carcinoma tissues, respectively. Case 5 had a background of liver cirrhosis. Morphologically, atypical large lymphoid cells were located in small blood vessels and capillary lumen, with little cytoplasm, hyperchromasia, prominent nucleoli, and obvious mitotic figures. Immunohistochemically, the IVLBCL tumor cells expressed CD20 and PAX5; 2 cases were CD5 positive. One of the 5 cases was GCB phenotype, and 4 cases were non-GCB phenotype. All cases expressed C-MYC (positive rate was 10%-40%). PD-L1 was positive in 4 cases (positive rate was 60%-90%). Ki-67 proliferation index was 70%-90%. CKpan, CD3, TDT, and CD34 were negative. In case 2, meningioma cells were positive for PR, EMA, and vimentin, but negative for CKpan and PD-L1. In case 3, renal carcinoma cells were positive for CKpan, PAX8, EMA, vimentin, CAⅨ and CD10, while PD-L1 was negative. No EBER expression (by in situ hybridization) or C-MYC gene translocation (FISH, break-apart probe) was detected in any of the 5 cases. Three patients were followed up, and all died within 1-13 months. Conclusions: IVLBCL is a highly aggressive lymphoma, with occult clinical manifestations and poor prognosis. Collision tumors of IVLBCL are extremely rare. A better understanding of IVLBCL would help pathologists avoid misdiagnoses.

Abstract
PURPOSE The Blood First Assay Screening Trial (BFAST) is a prospective study using next-generation sequencing (NGS) of circulating tumor DNA (ctDNA) in treatment-naïve advanced/metastatic non-small-cell lung cancer (NSCLC). We compared liquid biopsy to tissue testing and analyzed genomic alterations in Taiwanese patients with NSCLC using the BFAST database. MATERIALS AND METHODS A total of 269 patients underwent FoundationOne Liquid Companion Diagnostic (F1LCDx) assay at the National Taiwan University Hospital, of whom 264 underwent tissue-based genetic testing also. We analyzed the actionable mutations and the concordance between tissue-based genetic testing, which was limited to EGFR, ALK, ROS1, and BRAF, in a real-life clinical setting and blood-based NGS in the clinical trial. Additionally, we analyzed the co-occurring genomic alterations from the blood-based ctDNA assay. RESULTS A total of 76.2% patients showed actionable mutations. Standard tissue testing did not detect known driver alterations in about 22.7% of the patients (sensitivity, 70.24%). Liquid NGS detected additional mutations (RET, KRAS, MET, and ErbB2) in 14% of the patients, which went undetected by the standard-of-care testing. The complementary use of ctDNA NGS increased the detection rate by 42%. The F1LCDx assay had a sensitivity of 83.41%. Lower tumor and metastasis stages predicted nondetected blood-based NGS ctDNA results. Common co-occurring mutations in the blood-based NGS ctDNA assay were TP53, DNMT3A, TET2, PIK3CA, CTNNB1, and RB1. Among the patients with EGFR-mutated NSCLC, TET2 co-occurring alterations correlated with shorter progression-free survival of EGFR tyrosine kinase inhibitor treatment. CONCLUSION NGS ctDNA analysis in comprehensive genetic testing improves actionable mutation identification, vital for treating Asian NSCLC cases with high actionable mutation rates. Lower stages correlated with undetected blood-based NGS ctDNA assay results.

Abstract
Allergic disease is a systemic disease that affects multiple systems. Respiratory tract and skin are the most frequently involved organs of allergies, which include allergic rhinitis, asthma, acute and chronic urticaria, atopic dermatitis, etc.. They are closely correlated clinically. Respiratory allergies and skin allergies often occur in one patient in the form of synchronous occurrence, synchronous aggravation or mutual transfer of symptoms, and early atopic dermatitis in infants is an independent risk factor of respiratory allergy. Type Ⅰ hypersensitivity is the most common immunologic mechanism of respiratory and skin allergies, which are mediated by allergens induction, multiple immune cells and inflammatory cells involvement, and IgE medicated mast cell degranulation. This present article provides a brief review on the epidemiology, tissue origin, and pathogenesis of respiratory airway allergy and skin allergy, in order to provide new ideas and reference basis for clinical diagnosis and treatment and the development of allergic disease prevention strategies.

Abstract
Objective: To investigate the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) in the differential diagnosis of diabetic nephropathy (DN) and non-diabetic renal disease (NDRD) among patients with type 2 diabetes mellitus (T2DM). Methods: A diagnostic test. In this prospective study, patients with T2DM who underwent both IVIM-DWI and renal biopsy at the First Medical Center of Chinese PLA General Hospital between October 2017 and September 2021 were consecutively enrolled. IVIM-DWI parameters including perfusion fraction (f), pure diffusion coefficient (D), and pseudo-diffusion coefficient (D*) were measured in the renal cortex, medulla, and parenchyma. Patients were divided into the DN group and NDRD group based on the renal biopsy results. IVIM-DWI parameters, clinical information, and diabetes-related biochemical indicators between the two groups were compared using Student's t-test or Mann-Whitney U test. The correlation of IVIM-DWI parameters with diabetic nephropathy histological scores were analyzed using Spearman's correlation analyzes. The diagnostic efficiency of IVIM-DWI parameters for distinguishing between DN and NDRD were assessed using the receiver operating characteristic (ROC) curves. Results: A total of 27 DN patients and 23 NDRD patients were included in this study. The DN group comprised 19 male and 8 female patients, with an average age of 52±9 years. The NDRD group comprised 16 male and 7 female patients, with an average age of 49±10 years. The DN group had a higher D* value in the renal cortex and a lower f value in the renal medulla than the NDRD group (9.84×10-3 mm2/s vs. 7.35×10-3 mm2/s, Z=-3.65; 41.01% vs. 46.74%, Z=-2.29; all P<0.05). The renal medulla D* value was negatively correlated with DN grades, interstitial lesion score, and interstitial fibrosis and tubular atrophy (IFTA) score (r=-0.571, -0.409, -0.409; all P<0.05) while the renal cortex f value was positively correlated with vascular sclerosis score (r=0.413, P=0.032). The renal cortex D* value had the highest area under the curve (AUC) for discriminating between the DN and NDRD groups (AUC=0.802, sensitivity 91.3%, specificity 55.6%). Conclusion: IVIM-derived renal cortex D* value can be used non-invasively to differentiate DN from NDRD in patients with T2DM that can potentially facilitate individualized treatment planning for diabetic patients.

Abstract
Objective: To explore the molecular markers related to lymph node metastasis of prostate cancer (PCa) based on bioinformatics technology and carry out clinical verification. Methods: The differentially expressed genes of PCa with lymph node metastasis were screened from geo data, and the hub genes of the gene co expression network were constructed. The hub genes were incorporated into the support vector machine model to evaluate its prediction efficiency. The hub genes were verified in the TCGA data set and analyzed for immune infiltration. The clinical data of 80 patients with prostate cancer in the Fourth Hospital of Hebei Medical University from January 2019 to December 2022 were collected. The logistic risk model was used to evaluate the prediction efficiency of hub gene metastasis. Results: Five hub genes (GSK3B, TP53, PSMC6, SUMO1, PIK3CA) were identified, and the support vector machine model constructed by them had good diagnostic value (the accuracy rate was 83.87%). TCGA validation results showed that only PSMC6 was significantly differentially expressed in PCa tissues with lymph node metastasis (P<0.001). The results of immune infiltration analysis showed that the expression of PSMC6 was significantly correlated with 9 kinds of immune cells (B cells, DC, IDC, etc.). Clinical information analysis showed that the expression of PSMC6 was significantly correlated with lymph node metastasis, PSA value, T stage and Gleason score (P<0.01). Univariate logistic results showed that T stage (OR=3.230, 95%CI:1.192-8.757, P=0.021), Gleason score (OR=4.627, 95%CI:2.212-9.677, P<0.001), PSMC6 (OR=25.235, 95%CI:5.326-119.560, P<0.001) could be used as predictors of lymph node metastasis. Multivariate logistic analysis showed that PSMC6 (OR=16.537, 95%CI:2.928-93.393, P=0.001) could be used as an independent risk factor for predicting lymph node metastasis. Conclusion: PSMC6 may be used as a potential molecular marker for judging lymph node metastasis in patients with PCa.

Abstract
Objective: To investigate the surgical method and clinical effects of the modified proper digital artery island flap in repairing complex fingertip defects. Methods: A retrospective observational study was conducted. From January 2017 to December 2021, 15 patients (15 fingers) with complex fingertip defects, involving the pulp, nail bed, and lateral wall of the nail, who met the inclusion criteria were admitted into General Hospital of Northern Theater Command, including 11 males and 4 females, aged from 18 to 55 years. The area of the post debridement wound was from 2.5 cm×2.0 cm to 3.5 cm×3.5 cm, and all the wounds were repaired by using modified proper digital artery island flap (including 3 parts: main flap, tongue-shaped flap, and triangular flap), of which the main flap was used to cover the finger pulp defect, the tongue-shaped flap was used to cover the nail bed and the nail lateral wall defect, and the triangular flap was inserted into the edge of the finger pulp wound to cover the vessel pedicle. The range of the flap ranged from 3.0 cm×2.0 cm to 4.5 cm×3.0 cm. The wound at the donor site was repaired with full-thickness skin graft of the groin, and the donor site of the skin graft was sutured directly. After operation, the survival of the flap and skin graft as well as and the appearance of the affected finger were observed. During the follow-up, the fingertip morphology of the affected finger was observed, two-point discrimination distance of the affected finger pulp was measured, and the patients' satisfaction with the efficacy (including very satisfied, satisfied, and dissatisfied) was asked, and the affected finger function was evaluated by the total active movement (TAM) system evaluation standard recommended by American Academy for Surgery of Hand. Results: After operation, the main flaps and skin grafts in 15 patients all survived; but the incision at the edge of tongue-shaped flap in one patient healed poorly, and one patient developed venous stasis at the distal end of the tongue-shaped flap; the triangular flap at the pedicle was slightly bloated in the early postoperative period and became smooth after 2 to 3 months. Overall, two patients developed subcutaneous hematoma in their flaps. All the complications were healed by appropriate dressing change, suture removal, or compression bandaging. After operation, the appearance of the flap was full and formed a prominent fingertip shape. During the follow-up of 6 months to 5 years, the fingertips of the affected fingers were prominent and full; the two-point discrimination distance of the affected finger pulp was (8.6±1.4) mm; 8 patients were very satisfied with the efficacy, 6 patients were satisfied, and one patient was dissatisfied; the functional assessment of the affected fingers were all excellent. Conclusions: The modified proper digital artery island flap can repair complex fingertip defects involving the pulp, nail bed, and lateral wall of the nail. The operation is simple, and the shape and function of the fingertip are good after surgery.

Abstract
Objective: To evaluate the efficacy and safety of an improved overlength biliary stent in the treatment of bile duct stricture. Methods: Prospective randomized controlled study. Patients with bile duct stricture in Peking University International Hospital from February 2016 to June 2021 were randomly divided into the conventional plastic biliary stents (CPBS) group and the improved overlength biliary stents (IOBS) group by envelope random method. CPBS or IOBS were placed after endoscopic retrograde cholangiopancreatography (ERCP) breast catheterization was successfully conducted and the stenosis length was determined by angiography. The incidence of postoperative complications, median patency time of postoperative stent and reoperation rate within 6 months were compared between the two groups, Kaplan-Meier method was used to draw the survival curve, and log-rank test was conducted to evaluate the safety and efficacy of IOBS in the treatment of bile duct stricture. Results: A total of 90 patients were included. There were 45 patients in IOBS group, including 28 males and 17 females, aged (67.2±11.7) years. There were 45 patients in CPBS group, including 26 males and 19 females, aged (64.6±14.4) years. The patients in the both groups were balanced and comparable. There were no significant differences in success rate of operation, operation time, hospitalization time, operation cost and prospective complication rate between the two groups (all P>0.05). There were no significant differences in the changes of liver function index before and 72 hours after operation between the two groups (both P>0.05). The median patency time of stents in IOBS group was longer than that in CPBS group [M(Q1, Q3), 201(155,246) vs 109(55,167) d, P=0.002].The IOBS group had lower reoperation rate than the CPBS group within 6 months [46.2% (18/39) vs 78.9%(30/38), P=0.003]. Conclusion: IOBS has good safety in the treatment of bile duct stricture and the clinical efficacy is superior to CPBS.

Abstract
Pulmonary auscultation is essential for detecting abnormal lung sounds during physical assessments, but its reliability depends on the operator. Machine learning (ML) models offer an alternative by automatically classifying lung sounds. ML models require substantial data, and public databases aim to address this limitation. This systematic review compares characteristics, diagnostic accuracy, concerns, and data sources of existing models in the literature. Papers published from five major databases between 1990 and 2022 were assessed. Quality assessment was accomplished with a modified QUADAS-2 tool. The review encompassed 62 studies utilizing ML models and public-access databases for lung sound classification. Artificial neural networks (ANN) and support vector machines (SVM) were frequently employed in the ML classifiers. The accuracy ranged from 49.43% to 100% for discriminating abnormal sound types and 69.40% to 99.62% for disease class classification. Seventeen public databases were identified, with the ICBHI 2017 database being the most used (66%). The majority of studies exhibited a high risk of bias and concerns related to patient selection and reference standards. Summarizing, ML models can effectively classify abnormal lung sounds using publicly available data sources. Nevertheless, inconsistent reporting and methodologies pose limitations to advancing the field, and therefore, public databases should adhere to standardized recording and labeling procedures.

Abstract
Objective: To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test. Methods: This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ (2) test. A kappa test was used to compare the consistency between groups. Results: After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea (Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences (P < 0.001). Conclusion: The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Abstract
Objective: To comprehensively assess the current status of extrauterine growth restriction (EUGR) in very preterm infants (VPI) and its associated factors in Chinese neonatal intensive care units (NICU). Methods: In this cohort study, 6 179 preterm infants born at <32 weeks' gestation were included, who were admitted to 57 hospitals in the China Neonatal Network in 2019 and hospitalized for ≥7 days. EUGR was evaluated by a cross-sectional definition (weight at discharge<10th percentile for postmenstrual age), a longitudinal definition (decline in weight Z score>1 from birth to discharge), and weight growth velocity. The comparison between infants with and without EUGR was conducted by t-test, Mann-Whitney U test or χ2 test as appropriate. Multivariable Logistic regression models were used to evaluate associations between EUGR with different definitions and maternal and neonatal factors, clinical practices, and neonatal morbidities. Results: A total of 6 179 VPI were enrolled in the study, with a gestational age of (29.8±1.5) weeks and birth weight of (1 365±304) g; 56.2% (3 474) of them were male. Among them, 48.4% (2 992 VPI) were cross-sectional EUGR and 74.9% (4 628 VPI) were longitudinal EUGR. Z score of weight was (0.13±0.78) at birth and decrease to (-1.35±0.99) at discharge. The weight growth velocity was 10.13 (8.42, 11.66) g/(kg·d). Multivariate Logistic regression analysis showed that among the influential factors that could be intervened after birth, late attainment of full enteral feeds (ORadjust=1.01, 95%CI 1.01-1.02, P<0.001; ORadjust=1.01, 95%CI 1.01-1.02, P<0.001), necrotizing enterocolitis≥Ⅱstage (ORadjust=2.64, 95%CI 1.60-4.35, P<0.001; ORadjust=1.62, 95%CI 1.10-2.40, P<0.001) and patent ductus arteriosus (ORadjust=1.94, 95%CI 1.50-2.51, P<0.001; ORadjust=1.63, 95%CI 1.29-2.06, P<0.001) were all associated with increased risks of both cross-sectional and longitudinal EUGR. In addition, late initiation of enteral feeds (ORadjust=1.06, 95%CI 1.02-1.09, P=0.020) and respiratory distress syndrome (ORadjust=1.45, 95%CI 1.24-1.69, P<0.001) were all associated with cross-sectional EUGR. Breast milk feeding (ORadjust=1.33, 95%CI 1.05-1.68, P<0.001) was associated with a higher risk of longitudinal EUGR. Conclusions: The incidence of EUGR in VPI in China is high. Some modifiable risk factors provide priorities to improve postnatal growth for VPI. Nutritional management of VPI and the efforts to decrease the incidence of complications are still the focus of clinical management in China.

Abstract
Objective: To investigate the influence of clinical administration of dobutamine on blood perfusion in free flap repair of diabetic foot wounds. Methods: A prospective self-controlled study was conducted. From January to November 2022, 20 patients with diabetic foot who met the inclusion criteria were hospitalized in the Department of Burns and Plastic Surgery of Affiliated Hospital of Zunyi Medical University, including 9 males and 11 females, aged from 44 to 75 years, with the foot wounds area ranging from 5 cm×4 cm to 20 cm×10 cm, which were repaired by free anterolateral thigh flaps. Heart rate (HR) and mean arterial pressure (MAP) were recorded before anesthesia induction, 10 minutes after vascular recanalization, when the target blood pressure (i.e., MAP being 6-10 mmHg (1 mmHg=0.133 kPa) higher than that before anesthesia induction) was reached after infusion of dobutamine, and 10 minutes after tracheal catheter removal. Additionally, indocyanine green, a contrast agent, was injected intravenously at 10 minutes after vascular recanalization and when the target blood pressure was reached after infusion of dobutamine to assess flap blood perfusion using infrared imager, and the area ratio of flaps with hyperperfusion and hypoperfusion was calculated. Other recorded variables included flap harvesting area, surgical duration, total fluid infusion amount, infusion dose and total usage of dobutamine, intraoperative adverse events, postoperative flap complications, and follow-up outcomes. Data were statistically analyzed with paired sample t test, analysis of variance for repeated measurement, Bonferroni method, and generalized estimating equation. Results: Compared with those before anesthesia induction, HR and MAP of patients were significantly decreased at 10 minutes after vascular recanalization (P<0.05), while HR and MAP of patients were significantly increased when the target blood pressure was reached after infusion of dobutamine (P<0.05). Compared with those at 10 minutes after vascular recanalization, HR and MAP of patients were significantly increased when the target blood pressure was reached after infusion of dobutamine and at 10 minutes after tracheal catheter removal (P<0.05). Compared with those when the target blood pressure was reached after infusion of dobutamine, HR and MAP of patients were significantly decreased at 10 minutes after tracheal catheter removal (P<0.05). The area ratio of flaps with hyperperfusion of patients was 0.63±0.11 when the target blood pressure was reached after infusion of dobutamine, which was significantly higher than 0.31±0.09 at 10 minutes after vascular recanalization (t=-9.92, P<0.05). The area ratio of flaps with hypoperfusion of patients was 0.12±0.05 when the target blood pressure was reached after infusion of dobutamine, which was significantly lower than 0.45±0.10 at 10 minutes after vascular recanalization (t=17.05, P<0.05). The flap harvesting area of patients was (174±35) cm², the surgical duration was (372±52) min, the total fluid infusion amount was (2 485±361) mL, the infusion dose of dobutamine was 3-13 μg·kg⁻¹·min⁻¹, and the total usage of dobutamine was 5.7 (2.1, 9.7) mg. Two patients showed a significant increase in MAP during the infusion of dobutamine compared with that at 10 minutes after vascular recanalization, but before reaching 6 mmHg higher than that before anesthesia induction, their HR had reached the maximum (over 130 beats/min). The HR gradually returned to around 90 beats/min after the infusion of dobutamine was stopped. On post operation day 2, one patient had partial necrosis at the distal part of the flap, which was repaired by transplantation of thin split-thickness skin graft from the opposite thigh. During the follow-up of 3 to 6 months after operation, all the flaps survived well, with soft texture and well-formed shape, and no adverse cardiovascular events of patients were reported. Conclusions: The administration of dobutamine in free flap repair of diabetic foot wounds can significantly improve the MAP of patients, expand the area of hyperperfusion, reduce the area of hypoperfusion, and enhance the flap viability, with promising short-term follow-up results, which is suitable for promotion in clinical applications.

Abstract
Objective: To assess the prevalence, risk factors and treatment of anemia in patients with chronic kidney disease (CKD). Methods: A descriptive method was used to analyze the prevalence and treatment of anemia in CKD patients based on regional health data in Yinzhou District of Ningbo during 2012-2018. The multivariate logistic regression analysis was used to identify independent influence factors of anemia in the CKD patients. Results: In 52 619 CKD patients, 15 639 suffered from by anemia (29.72%), in whom 5 461 were men (26.41%) and 10 178 were women (31.87%), and anemia prevalence was higher in women than in men, the difference was significant (P<0.001). The prevalence of anemia increased with stage of CKD (24.77% in stage 1 vs. 69.42% in stage 5, trend χ2 test P<0.001). Multivariate logistic regression analysis revealed that being women (aOR=1.57, 95%CI: 1.50-1.63), CKD stage (stage 2: aOR=1.10, 95%CI: 1.04-1.16;stage 3: aOR=2.28,95%CI: 2.12-2.44;stage 4: aOR=4.49,95%CI :3.79-5.32;stage 5: aOR=6.31,95%CI: 4.74-8.39), age (18-30 years old: aOR=2.40,95%CI: 2.24-2.57, 61-75 years old: aOR=1.35,95%CI:1.28-1.42, ≥76 years old: aOR=2.37,95%CI:2.20-2.55), BMI (<18.5 kg/m2:aOR=1.29,95%CI: 1.18-1.41;23.0-24.9 kg/m2:aOR=0.79,95%CI: 0.75-0.83;≥25.0 kg/m2:aOR=0.70,95%CI: 0.66-0.74), abdominal obesity (aOR=0.91, 95%CI: 0.86-0.96), chronic obstructive pulmonary disease (aOR=1.15, 95%CI: 1.09-1.22), cancer (aOR=3.03, 95%CI: 2.84-3.23), heart failure (aOR=1.44, 95%CI: 1.35-1.54) and myocardial infarction (aOR=1.54, 95%CI:1.16-2.04) were independent risk factors of anemia in CKD patients. Among stage 3-5 CKD patients with anemia, 12.03% received iron therapy, and 4.78% received treatment with erythropoiesis-stimulating agent (ESA) within 12 months after anemia was diagnosed. Conclusions: The prevalence of anemia in CKD patients was high in Yinzhou. However, the treatment rate of iron therapy and ESA were low. More attention should be paid to the anemia management and treatment in CKD patients.

Abstract
Objective: To evaluate the diagnostic value of multiparametric magnetic resonance imaging (mpMRI) based models in the assessment of extra-prostatic extension (EPE) of prostate cancer. Methods: This retrospective study included 168 consecutive men with prostate cancers [aged 48 to 82 (66.6±6.8) years] who underwent radical prostatectomy and preoperative mpMRI examinations at the First Medical Center of the PLA General Hospital from January 2021 to February 2022. According to European Society of Urogenital Radiology (ESUR) score, EPE grade and mEPE score, all cases were independently evaluated by two radiologists, with disagreement reviewed by a senior radiologist as the final result. The diagnostic performance of each MRI-based model for pathologic EPE prediction was assessed using receiver operating characteristic curve (ROC), and the differences between the corresponding area under the curve (AUC) were compared using the DeLong test. The weighted Kappa test was used to evaluate the inter-reader agreement of each MRI-based model. Results: A total of 62 (36.9%) prostate cancer patients had pathologic confirmed EPE after radical prostatectomy. The AUC of ESUR score, EPE grade and mEPE score for predicting pathologic EPE were 0.836 (95%CI: 0.771-0.888), 0.834 (95%CI: 0.769-0.887) and 0.785 (95%CI: 0.715-0.844), respectively. The AUC of ESUR score and EPE grade were both superior to that of mEPE score with significant differences (all P<0.05), while there was no significant difference between the ESUR score and EPE grade models (P=0.900). EPE grading and mEPE score had good inter-reader consistency, with weighted Kappa values of 0.65 (95%CI: 0.56-0.74) and 0.74 (95%CI: 0.64-0.84), respectively. The inter-reader consistency of ESUR score was moderate, and the weighted Kappa value was 0.52 (95%CI: 0.40-0.63). Conclusion: All MRI-based models showed good preoperative diagnostic value in predicting EPE, among which the EPE grade resulted in more reliable performance with substantial inter-reader agreement.

Abstract
OBJECTIVE There is concern that the coronavirus disease (COVID-19) vaccine may trigger or worsen autoimmune diseases. The objective of this study was to determine the impacts of COVID-19 vaccination on symptom severity in patients with myasthenia gravis (MG). METHODS A total of 106 enrolled patients with MG who were vaccinated against COVID-19 were followed up, and a questionnaire was used to document in detail the exacerbation of muscle weakness after vaccination and all other uncomfortable reactions after vaccination. Demographic, clinical characteristics, medication, and vaccination data were collected by follow-up interview. The main observation outcome was whether the MG symptoms of patients were exacerbated. The definition of exacerbation is according to the subjective feeling of the patient or a 2-point increase in daily life myasthenia gravis activity score relative to before vaccination, within 30 days after vaccination. RESULTS Of 106 enrolled patients [median age (SD) 41.0 years, 38 (35.8%) men, 53 (50.0%) with generalized MG, 74 (69.8%) positive for acetylcholine receptor antibody, and 21 (19.8%) with accompanying thymoma], muscle weakness symptoms were stable in 102 (96.2%) patients before vaccine inoculation. Muscle weakness worsened in 10 (9.4%) people after vaccination, of which 8 patients reported slight symptom worsening that resolved quickly (within a few days). Two (1.9%) of patients showed serious symptom aggravation that required hospitalization. CONCLUSION Our results suggest that inactivated virus vaccines against COVID-19 may be safe for patients with MG whose condition is stable. Patients with generalized MG may be more likely to develop increased muscle weakness after vaccination.

Abstract
Abstract
Background: The Blood First Assay Screening Trial (BFAST) (NCT03178552) is a prospective study screening for actionable genetic alterations using NGS of ctDNA among patients with treatment-naive advanced or metastatic NSCLC. We aimed to perform a more systematic investigation of genomic alterations in Asia/Taiwan NSCLC patients through the BFAST database at NTUH.
Materials and Methods: There was a total of 269 patients enrolled and receiving FoundationOne Liquid Companion Diagnostic (F1LCDx) assay at cancer diagnosis between Feb, 2019 and Mar, 2022 in NTUH. The concordance of tissue-based genetic testing in the real-life clinical setting and the blood-based NGS testing in the clinical trial were analyzed. The co-occurrence of genomic alterations detected with blood-based NGS ctDNA assay were also interpreted.
Results: A total of 206 patients (76.5%) detected driver mutations. Tissue-based genetic testing in the real-life clinical setting missed driver mutations in 67 (24.9%) patients with a sensitivity of 67.32%. Liquid NGS detected 38 (14%) patients with RET, KRAS, Met or ErbB2 mutations which were beyond the scope of current genetic testing in the clinical settings. Also, the F1LCDx assay detected more uncommon EGFR mutations than the Roche Cobas EGFR Mutation Test V2 (P < 0.0001). Thirty-four (12.6%) patients had non-detected results in the F1LCDx assay which produced a sensitivity of 83.41%. By multivariate analysis, the predictors associated with discordant blood-based NGS ctDNA results were T stage (odds ratio [OR] 0.35, 95% confidence interval [CI] 0.15-0.79, p = 0.012) and M stage (OR 0.21, 95% CI 0.09-0.49, p < 0.0001). The most common co-occurring mutations in the blood-based NGS ctDNA assay were TP53, DNMT3A, TET2, PIK3CA and CTNNB1. Among the EGFR mutant population, first-generation compared to third-generation TKI use (hazard ratio [HR] = 0.43, 95% CI 0.22-0.85, P=0.02) and co-occurring genomic alterations in TET2 (HR = 2.35, 95% CI 1.15-3.48, P=0.02) were associated with shorter progression free survival of EGFR TKIs treatment in multivariate analysis. Disease stage was the only factor associated with overall survival in the EGFR mutant population.
Conclusion: NGS ctDNA analysis provided a more comprehensive genetic testing than conventional single gene testing kits. The lower stage which could imply lower or lack of ctDNA shedding into the blood was associated with a discordant result of the blood-based NGS ctDNA assay. Co-occurring mutations might have an impact on the treatment duration of EGFR-TKI.

Abstract
Objective: To investigate and analyze the occurrence and the related risk factors of gastrointestinal polypectomy accompanied by bleeding in patients with liver cirrhosis. Methods: 127 cases of gastrointestinal polyps with cirrhosis who had endoscopy at the Endoscopic Center of Tianjin Third Central Hospital between November 2017 and November 2020 were collected. At the same time, 127 cases of gastrointestinal polyps with non-cirrhosis that were treated by endoscopy were collected for comparison. The occurrence of hemorrhagic complications between the two groups was compared. The effects of age, sex, liver function, peripheral blood leukocytes, hemoglobin, platelets, blood glucose, the international normalized ratio (INR), polyp resection method, polyp location, size, number, endoscopic morphology, pathology, the presence or absence of diabetes, portal vein thrombosis, and esophageal varices on polypectomy bleeding in the cirrhosis group were analyzed. The measurement data between groups were compared using the t-test and rank sum test. The χ (2) test or Fisher's exact probability method, and multivariate logistic regression analysis were used for the comparison of categorical data between groups. Results: The number of polypectomy bleeding cases in the cirrhotic group was 21, with a bleeding rate of 16.5%. The number of bleeding cases in the non-cirrhotic group was 3, with a bleeding rate of 2.4%. The bleeding rate was higher in the cirrhosis group when polypectomy was performed (χ (2) = 14.909, P < 0.001). A univariate analysis of the risk factors for gastrointestinal polypectomy associated with bleeding in patients with liver cirrhosis showed that liver function grading, platelets, INR, hemoglobin, degree of esophageal and gastric varices, and the location, shape, size, and pathology of the polyps had a statistically significant impact on bleeding (P < 0.05). Multivariate logistic regression analysis showed that liver function grade, degree of varicose veins, and polyp location were independent risk factors for bleeding. Patients with Child-Pugh B or C grade liver function were more likely to bleed than those with Child-Pugh A grade (OR = 4.102, 95% CI 1.133 ~ 14.856), gastric polyps were more likely to bleed than colorectal polyps (OR = 27.763, 95% CI 5.567 ~ 138.460), and severe esophagogastric varices were more likely to bleed than no varices or mild to moderate varices (OR = 7.183, 95% CI 1.384 ~ 37.275). Conclusion: Cirrhotic population has higher risk of bleeding during endoscopic gastrointestinal polypectomy than the non-cirrhotic population. Cirrhotic patients with Child-Pugh grades B or C liver function, polyps located in the stomach, severe esophagogastric varices, and other high-risk factors should be listed as a relative contraindication for endoscopic polypectomy.

Abstract
Objective: To investigate the expression and significance of protease activated receptor 2 (PAR2) in ovarian epithelial carcinoma. Methods: PAR2 mRNA expression levels in 410 cases of epithelial ovarian carcinoma and 88 cases of human normal ovary were analyzed from cancer Genome Atlas (TCGA) database and tissue genotypic expression database (GTEx). Immunohistochemical (IHC) staining of PAR2 protein was performed in 149 patients with ovarian cancer who underwent primary surgical treatment at Cancer Hospital of Chinese Academy of Medical Sciences. Then the relationship between mRNA/protein expression of PAR2 and clinicopathological features and prognosis was analyzed. Gene functions and related signaling pathways involved in PAR2 were studied by enrichment analysis. Results: The mRNA expression of PAR2 in epithelial ovarian carcinoma was significantly higher than that in normal ovarian tissue (3.05±0.72 vs. 0.33±0.16, P=0.004). There were 77 cases showing positive and 19 showing strong positive of PAR2 IHC staining among the 149 patients, accounting for 64.4% in total. PAR2 mRNA/protein expression was closely correlated with tumor reduction effect and initial therapeutic effect (P<0.05). Survival analysis showed that the progression free survival time (P=0.033) and overall survival time (P=0.011) in the group with high PAR2 mRNA expression was significantly lower than that in the low PAR2 mRNA group. Multivariate analysis showed tumor reduction effect, initial therapeutic effect were independent prognostic factors on both progression-free survival and overall survival (P<0.05). The progression-free survival (P=0.016) and overall survival (P=0.038) of the PAR2 protein high expression group was significantly lower than that of the low group. Multivariate analysis showed PAR2 expression, initial treatment effect and chemotherapy resistance were independent prognostic factors on both progression-free survival and overall survival (P<0.05). Based on Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), PAR2 target genes were mainly enriched in function related to intercellular connection, accounting for 40%. Gene enrichment analysis (GSEA) showed that the Wnt/β-catenin signaling pathway (P=0.023), the MAPK signaling pathway (P=0.029) and glycolysis related pathway (P=0.018) were enriched in ovarian cancer patients with high PAR2 mRNA expression. Conclusions: PAR2 expression is closely related to tumor reduction effect, initial treatment effect and survival of ovarian cancer patients. PAR2 may be involved in Wnt/β-catenin signaling pathway and intercellular connection promoting ovarian cancer invasion and metastasis.

Abstract
BACKGROUND Evidence of associations between psychological symptoms and tumor necrosis factor (TNF)-α level is scant, as is evidence on sex differences in associations for children and adolescents with obesity. This study examined sex differences in associations between psychological symptoms (self-concept, anxiety, depression, anger, and disruptive behavior) and TNF-α level in Taiwanese children and adolescents with healthy weight, overweight, or obesity. METHODS In 2010, 564 first, fourth, and seventh graders-comprising 250 children with overweight or obesity (44.3 %), 330 adolescents (58.5 %), and 303 males (53.7 %)-underwent a health examination and blood sampling and completed a questionnaire. RESULTS A significantly higher TNF-α level was found in children and adolescents with healthy weight than in those with overweight or obesity (median: 14.5 vs. 4.1 (pg/mL); p < 0.001). In multiple linear regression models, anxiety was significantly positively associated with TNF-α level in female participants with healthy weight (β = 0.11 per 10 increments in anxiety, 95 % confidence interval = 0.01-0.22). LIMITATIONS Given the cross-sectional nature of the study, no inferences of causal relationships among TNF-α level, obesity, and psychological symptoms could be made. CONCLUSIONS The findings enrich the literature on the TNF-α-psychological symptom association. Sex differences were found in children and adolescents without obesity rather than in those without obesity, and a higher TNF-α level was associated with increased anxiety in girls without obesity. The role of sex differences in the complex associations among psychological symptoms, TNF-α level, and overweight or obesity requires further investigation.

Abstract
The electronic excitation occurring on adsorbates at ultrafast timescales from optical lasers that initiate surface chemical reactions is still an open question. Here, we report the ultrafast temporal evolution of x-ray absorption spectroscopy (XAS) and x-ray emission spectroscopy (XES) of a simple well-known adsorbate prototype system, namely carbon (C) atoms adsorbed on a nickel [Ni(100)] surface, following intense laser optical pumping at 400 nm. We observe ultrafast (∼100 fs) changes in both XAS and XES showing clear signatures of the formation of a hot electron-hole pair distribution on the adsorbate. This is followed by slower changes on a few picoseconds timescale, shown to be consistent with thermalization of the complete C/Ni system. Density functional theory spectrum simulations support this interpretation.

Abstract
Objective: To evaluate the value of clear cell likelihood score (ccLS) in identifying renal oncocytoma (RO) and clear cell renal cell carcinoma (ccRCC). Methods: Retrospective data of pathologically confirmed 43 RO patients [24 men and 19 women, aged 22-77 (54±14) years] between February 2008 and September 2021 and 43 ccRCC patients [30 men and 13 women, aged 29-78 (56±12) years] between May and July 2021 were consecutively included in the department of radiology, Chinese PLA General Hospital. Two radiologists used ccLS to assess each case independently, and disagreements were resolved by consensus. The ability of ccLS to identify RO and ccRCC was examined by the receiver operating characteristic (ROC) curve which identified the best optimal diagnostic cut-off values, sensitivity, specificity, accuracy, positive predictive value, and negative predictive value. Results: The mean tumor diameter was 3.8 cm in RO patients and 3.7 cm in ccRCC patients. Central scar and segmental enhancement inversion (SEI) were more frequently observed in the RO group compared to the ccRCC group [53.5% (23∶43) versus 11.6% (5∶43) and 41.9% (18∶43) versus 7.0% (3∶43), respectively], with statistical differences (P<0.001). The ccLS scores in the RO group ranged from 1 to 4, while 79.0% of the cases were 3. The ccLS scores in the ccRCC group ranged from 2 to 5, while 72% of the cases were 4. The scores of the two groups were statistically different (P<0.001). The ccLS showed the best performance when the threshold was 4 according to the ROC curve. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of ccLS for distinguishing RO from ccRCC were 83.7%, 90.7%, 87.2%, 90.0%, and 84.8%, respectively, and the area under the ROC curve value was 0.879. Conclusion: The ccLS has credible sensitivity and specificity in differentiating renal oncocytoma from clear cell carcinoma, which may be helpful for the preoperative diagnosis.

Abstract
The Trachway video intubating stylet device facilitates the visualization of the airways of patients from the tip of an endotracheal tube (ETT) during intubation. The major limitations of Trachway are the restricted view due to secretions and the risk of a prolonged apnea during intubation. We conducted a bench study to verify the performance of an alternative, easily applicable airway device that allows better visualization of trackways during Trachway-assisted intubation and prevents the detrimental effects of apnea-related hypoxia. We conducted a bench study to thoroughly evaluate the oral-secretion-elimination ability of a newly designed oxygen delivery device (ODD) to improve vocal-cord visualization using the three commonly used ETT sizes (i.e., 7, 7.5, and 8 mm). Moreover, we measured the fraction of inspired oxygen (FiO2) under different, continuous oxygen-flow supplies (1-10 L/min) during intubation. Each condition was analyzed for a 2 min video-stylet-intubation period. The supplemental oxygen flow and FiO2 fraction achieved using our ODD were higher, and smaller ETTs exhibited better secretion elimination. The ODD, which can be easily coupled with Trachway stylets, enabled high-quality visualization during oxygen flows of 6-8 L/min, and higher FiO2 fractions were achieved at higher oxygen flow rates. The use of the ODD improved the visualization of the airways during video stylet-assisted intubations using the additional FiO2 supply. The ODD developed in this study improves the visualization of airways with Trachway stylets and enhances the safety of intubation.

Abstract
The pupil constricts in response to an increase in global luminance level, commonly referred to as the pupil light reflex. Recent research has shown that these reflex responses are modulated by high-level cognition. There is larger pupil constriction evoked by a bright stimulus when the stimulus location spatially overlaps with the locus of attention, and these effects have been extended to saccade planning and working memory (here referred to as pupil local-luminance modulation). Although research in monkeys has further elucidated a central role of the frontal eye field (FEF) and superior colliculus in the pupil local-luminance modulation, their roles remain to be established in humans. Through applying continuous theta-burst transcranial magnetic stimulation over the right FEF (and vertex) to inhibit its activity, we investigated the role of the FEF in human pupil local-luminance responses. Pupil light reflex responses were transiently evoked by a bright patch stimulus presented during the delay period in the visual- and memory-delay tasks. In the visual-delay task, larger pupil constriction was observed when the patch location was spatially aligned with the target location in both stimulation conditions. More interestingly, after FEF stimulation, larger pupil constriction was obtained when the patch was presented in the contralateral, compared to the ipsilateral visual field of the stimulation. In contrast, FEF stimulation effects were absence in the memory-delay task. Linear mixed model results further found that stimulation condition, patch location consistency, and visual field significantly modulated observed pupil constriction responses. Together, our results constitute the first evidence of FEF modulation in human pupil local-luminance responses.

Abstract
The interplay between various symmetries and electronic bands topology is one of the core issues for topological quantum materials. Spontaneous magnetism, which leads to the breaking of time-reversal symmetry, has been proven to be a powerful approach to trigger various exotic topological phases. In this Letter, utilizing the combination of angle-resolved photoemission spectroscopy, magneto-optical Kerr effect microscopy, and first-principles calculations, we present the direct evidence on the realization of the long-sought spontaneous ferromagnetism induced topological transition in soft ferromagnetic EuB_{6}. Explicitly, we reveal the topological transition is from Z_{2}=1 topological insulator in paramagnetic state to χ=1 magnetic topological semimetal in low temperature ferromagnetic state. Our results demonstrate that the simple band structure near the Fermi level and rich topological phases make EuB_{6} an ideal platform to study the topological phase physics.

Abstract
We report on carbon monoxide desorption and oxidation induced by 400 nm femtosecond laser excitation on the O/Ru(0001) surface probed by time-resolved X-ray absorption spectroscopy (TR-XAS) at the carbon K-edge. The experiments were performed under constant background pressures of CO (6x10-8 Torr) and O2 (3x10-8 Torr). Under these conditions, we detect two transient CO species with narrow 2π* peaks, suggesting little 2π* interaction with the surface. Based on polarization measurements, we find that these two species have opposing orientations: (1) CO favoring a more perpendicular orientation and (2) CO favoring a more parallel orientation with respect to the surface. We also directly detect gas-phase CO2 using a mass spectrometer and observe weak signatures of bent adsorbed CO2 at slightly higher X-ray energies than the 2π* region. These results are compared to previously reported TR-XAS results at the O K-edge where the CO background pressure was three times lower (2x10-8 Torr) while maintaining the same O2 pressure. At the lower CO pressure, in the CO 2π* region, we observed adsorbed CO and a distribution of OC-O bond lengths close to the CO oxidation transition state, with little indication of gas-like CO. The shift towards 'gas-like' CO species may be explained by the higher CO exposure, which blocks O adsorption, decreasing O coverage and increasing CO coverage. These effects decrease the CO desorption barrier through dipole-dipole interaction, while simultaneously increasing the CO oxidation barrier.

Abstract
Objective: To investigate the clinical effects of ultra-pulsed fractional carbon dioxide laser (UFCL) in the treatment of mild to moderate microstomia after burns. Methods: A retrospective observational study was conducted on 19 patients with mild to moderate microstomia after burns who were admitted to Inner Mongolia Baogang Hospital from January 2018 to January 2022, including 15 males and 4 females aged (35±14) years. Patients had an average course of 71 d of microstomia, with 8 cases of moderate microstomia and 11 cases of mild microstomia. All the patients received UFCL treatment every 2-3 months until the microstomia was corrected or the treatment bottleneck was reached. The times of UFCL treatment for patients and the time interval from the last treatment to the last follow-up were recorded. Before the first treatment and at the last follow-up, the opening degree of mouth (finger measurement method), oral gap width, and the distance between the upper and lower incisors during mouth opening were recorded. Before the first treatment and at the last treatment, the new Vancouver scar scale (VSS) was used to evaluate the scar. At the last follow-up, the degree of satisfaction was evaluated by the Likert 5 scale by the patients themselves, and the satisfaction ratio was calculated; the adverse reactions such as pigmentation, blisters, infection, and persistent erythema in the treatment area were counted. Data were statistically analyzed with Mann-Whitney rank sum test or paired sample t test. Results: Patients received UFCL treatment of 3 (2, 6) times. The interval from the last treatment to the last follow-up was 26 months at most and 4 months at least. At the last follow-up, the opening degree of mouth of patients was significantly improved than that before treatment (Z=4.68, P<0.01). At the last follow-up, the oral gap width of patients was (35±6) mm, and the distance between upper and lower incisors during mouth opening was (3.2±0.4) cm, which was significantly improved compared with those before treatment (with t values of 10.73 and 18.97, respectively, P<0.01). The VSS score after the last treatment was 4.1±1.6, which was significantly better than that before treatment (t=22.96, P<0.01). At the last follow-up, the satisfaction ratio of patients with treatment was 18/19, and no pigmentation, blisters, infection, persistent erythema, and other adverse reactions of all patients in the treatment area occurred, however, one of the patients reported that the disease recurred about half a year after treatment. Conclusions: UFCL is an effective method for treating mild to moderate microstomia after burns, with which patients are highly satisfied, and it is worth of further study and promotion.

Abstract
Purpose Inadequate inhaler technique and nonadherence to therapy are associated with poorer clinical outcomes in chronic obstructive pulmonary disease (COPD). Shared decision-making (SDM), based on clinical evidence, patient goals and preferences, improves quality of care. This study aims to investigate the initial patients’ choices of inhaler devices in patients with newly-diagnosed COPD after an SDM process. Patients and Methods We conducted a prospective, observational, multi-center study in four hospitals in Taiwan from December 2019 to July 2021. All treatment-naïve patients with newly-diagnosed COPD who were able to use three different inhalers of dual bronchodilators (Respimat®, Ellipta®, and Breezhaler®) in the outpatient setting were enrolled. After an SDM process, every patient was prescribed with one inhaler chosen by him- or herself. Errors of using inhalers were recorded after prescription of the inhaler, and at the follow-up visit a month later. The patients’ adherence, satisfaction score, and willingness to keep the initially chosen inhaler were investigated. Results In 109 enrolled patients, 43, 45, and 21 patients chose Respimat®, Ellipta®, and Breezhaler®, respectively. Patients chose different inhalers had similar rates of critical error on both visits, while the rates greatly decrease on the follow-up visit, no matter which inhaler devices they chose initially. The majority of patients had good adherence (use as the prescription daily, n = 79, 82%), satisfaction (satisfaction score ≥4, n = 70, 73%), and strong willingness to keep the initial inhaler (n = 89, 93%) on the follow-up visit regardless of disease severity and their comorbidities. Conclusion SDM might facilitate inhaler choosing, reduce inhaler errors (versus baseline) with good adherence, satisfaction and strong willingness to keep the initial inhaler in patients with newly-diagnosed COPD.

Abstract
Objective: To describe the clinical features, genetic characteristics, and diagnosis of Marsili syndrome, an extremely rare disease which should be differentiated from other fever disorders. Methods: The clinical data and diagnostic process of a case with Marsili syndrome, hospitalized in the Department of Respiratory and Critical Care Medicine, the Eighth Medical Center of Chinese PLA General Hospital in February 2021, were summarized. The exon regions of 20, 000 genes of peripheral blood were detected in the patient and her parents. Using key words of"Marsili syndrome"and"ZFHX2 gene mutation", the related literatures were searched in Wanfang and PubMed databases from January, 2000 to November, 2021. In addition, the literatures of congenital insensitivity to pain and anhidrosis were retrieved in Wanfang domestic database from the same period. Results: A 23-year-old female patient had suffered from recurrent fever for more than two years, accompanied by anhidrosis, insensitive to pain and weakened corneal reflex. The effect of non-steroidal anti-inflammatory drugs for fever was minimal. The ZFHX2 gene mutation was positive in the patient and her mother, while NTRK1 gene mutation specific to congenital insensitivity to pain with anhidrosis (CIPA) was negative. The ZFHX2 gene mutation was negative in her father. A total of 2 literatures of Marsili syndrome were retrieved and a total of 6 cases of Marsili syndrome in one family were reported worldwide up to now. These patients had a group of similar symptoms including fever, little or no sweating, and insensitivity to pain caused by skin burn and bone fracture. However, there was no abnormality in headache and visceral pain, and female patients' childbirth pain as well as tactile sensation in these cases. The corneal reflex was decreased or negative. They had less sensitivity to stimulus of capsaicin. The ZFHX2 gene mutation was positive, but NTRK1 gene was not detected in all patients. A total of 4 literatures were retrieved and a total of 34 cases of CIPA were reported in China. Though Marsili syndrome and CIPA exhibited a number of similar clinical manifestations, they were distinct diseases and had obviously different outcome. Conclusions: Marsili syndrome is an autosomal dominant genetic disease. It is extremely rare worldwide. In clinical practice, when a patient presents with unexplained recurrent fever and poor effect of non-steroidal anti-inflammatory drugs, especially with the symptoms of no sweating and insensitivity to pain, the possibility of Marsili syndrome should be considered and the ZFHX2 gene should be determined. Marsili syndrome appears to be a benign disease with a good prognosis. A definitive diagnosis can avoid ineffective treatment and its adverse effects. To our knowledge, there is currently no effective genetic therapy for this disease.

Abstract
Objective: To investigate the long-term outcomes of minimally invasive Oxford phase Ⅲ unicompartmental knee arthroplasty (UKA) for patients with medial compartment osteoarthropathy. Methods: The clinical data of 594 patients (701 knees) who underwent minimally invasive UKA with Oxford phase Ⅲ unicompartmental prosthesis at Department of Orthopedics,the Affiliated Hospital of Qingdao University from January 2007 to January 2016 were retrospectively analyzed.There were 155 males and 439 females,aged (62.6±10.9) years (range: 44 to 81 years),with a body mass index of (26.9±3.8) kg/m2 (range: 21.1 to 36.2 kg/m2).There were 359 left knees and 342 right knees,676 knees with osteoarthritis and 25 knees with idiopathic osteonecrosis of the medial femoral condyle.There were 487 cases underwent UKA (66 cases underwent UKA on one side and total knee arthroplasty on the other) and 107 cases underwent bilateral UKA.Patients' prosthetic survival,complications,range of motion(ROM) of the knee,visual analogue score (VAS),Western Ontario and McMaster University (WOMAC) osteoarthritis index,and American knee society score (KSS) were collected to assess clinical outcomes.Paired sample t test was used to compare the data before and after operation. Results: All patients completed the surgery successfully.There was no intraoperative fractures,postoperative infections or symptomatic vascular embolic disease occurred.The postoperative complications,including mobile bearing dislocation,prosthesis loosening,tibial plateau collapse,the lateral compartment degeneration and postoperative pain were occurred in 18 cases (3.0%,18/594).Thirteen patients suffered complications were transferred to total knee arthroplasty,4 underwent partial revision,if this was used as the endpoint of the study,the surgical success rate was 97.1% (577/594) and the prosthetic revision rate was 2.9%.The ROM was improved from(105.9±11.8)°preoperatively to (114.0±13.3)° at the last follow-up (t=10.796,P<0.01);the KSS clinical score was increased from 54.3±3.6 to 90.1±6.0 (P<0.01) and the functional score was increased from 55.9±3.9 to 87.5±5.7(t=124.325,P<0.01;t=110.985,P<0.01).The WOMAC osteoarthritis index was decreased from 54.8±6.7 to 9.2±3.1 at the last follow-up(t=150.860,P<0.01) and the VAS was decreased from 6.1±1.1 to 1.5±1.0 at the last follow-up(t=74.941,P<0.01). Conclusions: Minimally invasive Oxford phase Ⅲ UKA for medial compartment knee osteoarthritis has a favorable prosthesis survival rate,low revision rate,and few complications at long-term follow-up.Patients have significant improvement in knee function with satisfactory clinical outcomes.

Abstract
![]()
Carbide formation
on iron-based catalysts is an integral and, arguably,
the most important part of the Fischer–Tropsch synthesis process,
converting CO and H2 into synthetic fuels and numerous
valuable chemicals. Here, we report an in situ surface-sensitive study
of the effect of pressure, temperature, time, and gas feed composition
on the growth dynamics of two distinct iron–carbon phases with
the octahedral and trigonal prismatic coordination of carbon sites
on an Fe(110) single crystal acting as a model catalyst. Using a combination
of state-of-the-art X-ray photoelectron spectroscopy at an unprecedentedly
high pressure, high-energy surface X-ray diffraction, mass spectrometry,
and theoretical calculations, we reveal the details of iron surface
carburization and product formation under semirealistic conditions.
We provide a detailed insight into the state of the catalyst’s
surface in relation to the reaction.

Abstract
Objective: To evaluate the association between periodontitis and mild cognitive impairment (MCI), and explore the potential local oral risk factors for MCI. Methods: The study included 70 middle-aged and elderly subjects (44 females and 26 males) with periodontal disease who were first diagnosed by the Department of Periodontology or referred by the Department of Geriatrics in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2021 to January 2022. In this study, the control group consisted of periodontal disease patients without cognitive impairment, and the case group (MCI group) consisted of those diagnosed with MCI referred by the geriatrics specialists. Full-mouth periodontal examinations of all subjects were performed and periodontal indicators were recorded by periodontists, while digital panoramic radiographs were taken. The severity of periodontitis was defined according to the 1999 classification, and the staging and grading of periodontitis were defined according to the 2018 American Academy of Periodontology and European Federation of Periodontology classification. The mini-mental state examination scale was chosen by geriatricians to evaluate the cognitive function of the included subjects. The cubital venous blood was drawn to detect the expression levels of inflammatory factors such as hypersensitive C-reactive protein (hs-CRP), interleukin (IL)-1β, IL-6 and tumor necrosis factor-α(TNF-α) in serum. Independent-samples t test and chi-square test were used to analyze the differences in population factors, periodontal-related indexes and serum inflammatory factors between the two groups (α=0.05). Odds ratios (OR) for MCI according to the severity of periodontitis and main periodontal clinical indexes were calculated by binary Logistic analysis. Results: Thirty-nine subjects were included in the control group and thirty-one in the MCI group. The age of the study population was (58.3±6.2) years (range: 45-70 years). The comparison between two groups showed that the control group was with higher educational background (χ²=9.45, P=0.024) and 2.6 years younger than the MCI group [(57.1±6.0) years vs. (59.7±6.3) years, t=-1.24, P=0.082]. The number and proportion of moderate to severe periodontitis in control group were significantly lower compared to those in MCI group (17 cases with 43.6% vs. 23 cases with 74.2%, χ²=6.61, P=0.010), and the OR of moderate to severe periodontitis adjusted by age and educational background was 3.00 (95%CI: 1.01-8.86, P=0.048). Compared with the grading (χ²=5.56, P=0.062) of periodontitis, staging had a greater impact on MCI (χ²=7.69, P=0.041), moreover the proportion of MCI in stage Ⅰ grade A periodontitis was significantly lower than any other type of periodontitis (χ²=13.86, P=0.036). In addition, less presence of deep periodontal pockets [probing depth (PD)≥6 mm] (17.9% vs. 41.9%, χ²=4.87, P=0.027), fewer number of PD≥4 mm (6.48±6.70 vs. 11.03±8.91, t=-2.44, P=0.017), lower plaque index (1.42±0.56 vs. 1.68±0.57, t=-1.91, P=0.059) and gingival index (1.68±0.29 vs. 1.96±0.30, t=-3.93, P<0.001) were in the control group than in the MCI group. However, there were no significant differences between the two groups in the levels of serum inflammatory factors, such as hs-CRP, IL-1β, IL-6 and TNF-α (P>0.05). Conclusions: It appears a strong correlation between moderate to severe periodontitis and the incidence of MCI in middle-aged and elderly people. Moreover, deep and increased number of periodontal pockets, poor oral hygiene, and severe gingival inflammation can be potentially associated risk factors for MCI.
