Abstract
Objectives: To construct a nomogram prediction model using common preoperative indicators for early weight loss (EWL) 1 year after laparoscopic sleeve gastrectomy (LSG). Methods: Relevant data of obese patients who had undergone LSG from January 2015 to May 2022 in Fujian Medical University Union Hospital and Quanzhou First Hospital Affiliated Fujian Medical University were analyzed. Patients with a history of major abdominal surgery, severe gastroesophageal reflux disease, pregnancy within 1 year after surgery, or who were lost to follow-up were excluded, resulting in a total of 200 patients in the study (190 from Fujian Medical University Union Hospital and 10 from Quanzhou First Hospital Affiliated Fujian Medical University). The participants were 51 men and 149 women of a mean age 29.9±8.2 years and a body mass index (BMI) 38.7±6.5 kg/m2. All patients in this group underwent standardized LSG procedure. Achieving ideal weight (BMI≤25 kg/m2) 1 year after LSG was defined as goal of EWL. Logistic regression analyses were performed to identify factors that independently influenced EWL. These factors were incorporated into the nomogram model. Receiver operating characteristic (ROC) curves (the larger the area under the curve [AUC], the better the predictive ability and accuracy of the model), likelihood ratio test (higher likelihood ratio indicates greater model homogeneity), decision curve analysis (higher net benefit indicates a better model), Akaike information criterion (AIC; smaller AIC indicates a better model), and Bayesian information criterion (BIC; smaller BIC indicates a better model) were used to validate the predictive ability of the column line diagram model. Results: In this study of 200 obese patients who underwent LSG surgery, 136 achieved EWL goal, whereas the remaining 64 did not. The rate of EWL goal achievement of the entire group was 68.0%. Compared with patients who did not achieve EWL goal, those who did had lower BMI, alanine transaminase, aspartate transaminase, triglycerides, and higher cholesterol. Additionally, the proportion of female was higher and the proportions of patients with fatty liver and hypertension lower in those who achieved EWL goal (all P<0.05). Univariate and multivariate logistic regression analysis revealed that preoperative BMI (OR=0.852, 95%CI: 0.796-0.912, P<0.001), alanine transaminase (OR=0.992, 95%CI: 0.985-0.999, P=0.024), presence of fatty liver (OR=0.185, 95%CI: 0.038-0.887, P=0.035) and hypertension (OR=0.374, 95%CI: 0.144-0.969, P=0.043) were independently associated with failure to achieve EWL goal. Cholesterol (OR=1.428, 95%CI: 1.052-1.939, P=0.022) was independently associated with achieving EWL goal. We used the above variables to establish an EWL nomogram model. ROC analysis, the likelihood ratio test, decision curve analysis, and AIC all revealed that the predictive value of the model was better than that of BMI alone (nomogram model vs. BMI: area under the curve 0.840 vs. 0.798, P=0.047; likelihood ratio: 58.785 vs. 36.565, AIC: 193.066 vs. 207.063, BIC: 212.856 vs. 213.660). Conclusion: Our predictive model is more accurate in predicting EWL after LSG compared with using BMI.

Abstract
Objective: To explore the relationship between pathogenic gene, mutation and phenotype of left ventricular noncompaction (LVNC) patients and their family members. Methods: The subjects were the proband with LVNC and her family members. The medical history including electrocardiogram, echocardiography and cardiac magnetic resonance examination of the proband and family members were collected. Whole exome sequencing of the proband was performed, bioinformatics analysis focused on the genes related to hereditary cardiomyopathy. Candidate pathogenic sites were validated by Sanger sequencing. The clinical interpretation of sequence variants were classified according to American College of Medical Genetics and Genomics (ACMG) guidelines. Results: The proband carried a heterozygous variation of the MYBPC3 gene c.C2827T and the MYH7 gene c.G2221C. The proband's sister carried heterozygous variation of MYBPC3 gene c.C2827T. According to the ACMG guidelines, the variant was determined to be pathogenic. Conclusion: The missense variant of MYBPC3 gene c.C2827T and MYH7 gene c.G2221C are identified from the proband with LVNC and her family member, which provides a genetic basis for clinical diagnosis and genetic counseling of the patients and the family members with LVNC.

Abstract
Objective: To analyze the clinical characteristics of patients with severe immune checkpoint inhibitors (ICIs) related myocarditis. Methods: A retrospective study was conducted on the 50 patients with ICIs-related myocarditis in the multidisciplinary cardio-oncology clinic of Zhongshan Hospital affiliated to Fudan University from April 2020 to April 2022. The age of patients was (63.7±10.8) years old, including 37 males and 13 females. The patients were divided into the mild group (n=37) and the severe group (n=13) according to severity. The differences of basic characteristics, clinical manifestations, laboratory tests, auxiliary examination, combined irAEs, treatment and outcomes between the two groups of patients were analyzed. Results: The immunotherapy time [M(Q1,Q3)] of patients in the mild group and severe group were 81 (49, 134) and 24 (20, 116) days, respectively (P<0.05). In the severe group, the levels of cTnT [0.605 (0.317, 1.072) μg/L], NT-proBNP [1 126 (386, 1 744) ng/L], CK-MB [78 (48, 238) U/L], and CK-MM [240 (45, 6 543) U/L] were higher than those in the mild group [0.104 (0.045, 0.189) μg/L, 237 (39, 785) ng/L, 24 (20, 33) U/L, 108 (72, 168) U/L, respectively] (all P<0.05). The left ventricular ejection fraction of the severe group [64% (57%, 65%)] was lower than that of the mild group [66% (63%, 69%)] (P<0.05), and the incidence of conduction block (n=4, 4/13) and abnormal ventricular wall motion (n=4, 4/13), the incidence of ICIs-related myositis (n=10, 10/13), ICIs-related hepatitis (n=4, 4/13) and ICIs-related neurotoxicity (n=4, 4/13) were higher than those in the mild group (n=1, 2.7%; n=2, 5.4%; n=16, 43.2%; n=2, 5.4%; n=1, 2.7%, respectively) (all P<0.05). The proportion of patients receiving intensified immunosuppressive therapy and mortality rate in the severe group were 12/13 (n=12) and 4/13 (n=4), which were both higher than those in the mild group [10.8% (n=4) and 0] (both P<0.05). Conclusions: The incidence of ICIs-related myocarditis is not high, but the severe rate and mortality are high. The differential diagnosis of severe ICIs related myocarditis should be combined with myocardial markers, electrocardiogram and echocardiogram, and early diagnosis and treatment can improve the prognosis of patients.

Abstract
This study used machine learning techniques combined with routine blood cell analysis parameters to build preliminary prediction models, helping differentiate patients with depression from healthy controls, or patients with anxiety. A multicenter study was performed by collecting blood cell analysis data of Beijing Chaoyang Hospital and the First Hospital of Hebei Medical University from 2020 to 2021. Machine learning techniques, including support vector machine, decision tree, naïve Bayes, random forest and multi-layer perceptron were explored to establish a prediction model of depression. The results showed that based on the blood cell analysis results of healthy controls and depression group, the accuracy of prediction model reached as high as 0.99, F1 was 0.975. Receiver operating characteristic curve area and average accuracy were 0.985 and 0.967, respectively. Platelet parameters contributed mostly to depression prediction model. While, to random forest differential diagnosis model based on the data from depression and anxiety groups, prediction accuracy reached 0.68 and AUC 0.622. Age, platelet parameters, and average volume of red blood cells contributed the most to the model. In conclusion, the study researched on the prediction model of depression by exploring blood cell analysis parameters, revealing that machine learning models were more objective in the evaluation of mental illness.

Abstract
Objective: To investigate the oncological outcomes of active surveillance (AS) in patients showing thyroid nodules measuring≤1 cm with highly suspicious ultrasound features. Methods: A prospective single-center cohort study. A total of 534 patients with highly suspicious thyroid nodules (2015 American Thyroid Association Nodule Sonographic Patterns and Risk of Malignancy: High Suspicion) were enrolled in this study, the patients received AS at Peking Union Medical College Hospital between January 2017 and November 2022 to assess oncological outcomes (disease progression, recurrence/metastasis rate, etc). The patients were followed up every 6 months for physical examination and neck ultrasound examination. And the value of tumor volume changes in evaluating tumor enlargement was explored too. Results: There were 413 females and 121 males in this cohort, with a mean age of (42.6±11.8) years. During a median follow-up period of 45.6 months (ranged from 3.5 to 176.0 months), disease progression occurred in 26 patients (4.9%) with highly suspicious thyroid nodules, characterized by a minimum 3-mm increase in tumor diameter in 19 patients (3.6%) and lymph node metastases in 7 patients (1.3%). Forty-seven (8.8%) patients opted for delayed surgery, with 29 patients due to a change in preference. There was no significant differences in pathologic and follow-up outcomes between patients with disease progression and preference change. Patients aged≤40 years had a higher cumulative incidence of 5-year disease progression than those aged>40 years (4.9% vs 1.9%, P=0.060). No patients experienced distant metastases or deaths. Among the 595 high-risk thyroid nodules with continuous volume assessment results and an increase in nodule diameter of less than 3 mm (including all high-risk nodules in patients with single or multiple nodules), 184 (30.9%) and 79 (13.3%) nodules exhibited volume increases of more than 50% and 100%, respectively, in multiple measurements. Among the nodules with volume changes exceeding 50% and 100%, the proportion of nodules with a baseline tumor diameter of≤0.5 cm was significantly higher than those with a diameter of>0.5 cm, at 69.0% vs 31.0% (P<0.001) and 77.2% vs 22.8% (P<0.001), respectively. Conclusions: Active surveillance in patients with highly suspicious subcentimeter thyroid nodules has good short-term oncological outcomes and can be considered a safe alternative to surgery. Due to the large variability in the measurement results of tumor volume, it is not suitable as an indicator for evaluating tumor enlargement.

Abstract
Objective: To evaluate the efficacy of transcatheter arterial embolization (TAE) in the treatment of neuroendocrine neoplasm liver metastases (NENLM), analyze the prognosis and related factors. Methods: Clinical data of NENLM patients treated with TAE in the First Affiliated Hospital of Nanjing Medical University from January 2018 to March 2022 were retrospectively analyzed. Objective response rate (ORR), disease control rate (DCR), and adverse event rate after TAE were evaluated according to the Response Evaluation Criteria In Solid Tumors and the Common Terminology Criteria for Adverse Events. The prognosis was evaluated by median overall survival (mOS) and median progression-free survival (mPFS). The survival curve was plotted by Kaplan-Meier method. Multivariate Cox regression was used to analyze prognostic factors. Results: A total of 39 NENLM patients were included in this study, aged (53.3±10.3) (23-74) years old, including 23 males and 16 females. Among them, 9 cases had functional neuroendocrine neoplasms. There were 31 cases with primary sites locating in the digestive system, 32 cases with WHO G1 and G2 primary sites, 27 cases with abundant blood supply for liver metastases and 13 cases with liver tumor load >50%. Thirty patients received treatment of long-acting somatostatin analogue(SSA). A total of 123 TAE were performed in 39 cases, with an ORR of 38.5% (15/39) and a DCR of 76.9% (30/39). There were no serious adverse events of level 4-5 during the perioperative period. The median follow-up was 38.7 (95%CI: 31.3-46.1) months, with mOS of 37.3(95%CI: 27.0-47.5) months and mPFS of 12.6 (95%CI: 7.1-18.1) months. Multivariate Cox regression analysis found that the combination of long-term SSA treatment was an influencing factor for overall survival of patients (HR=0.207, 95%CI: 0.076-0.567, P=0.002). Conclusions: TAE can effectively reduce the load of liver metastases in patients with NENLM, and the combination of long-term SSA treatment can improve the ovreall survival of patients.

Abstract
Objective: To evaluate the associations between the renalase single-nucleotide polymorphisms rs2576178 and rs10887800 and the risk of hypertension in OSA patients. Methods: A total of 3, 570 male OSA subjects diagnosed via standard polysomnography were included in this retrospective study. We recorded anthropometric, genomic, and polysomnographic parameters and blood pressure levels. All subjects were divided into four groups based on quartiles of the apnea-hypopnea index (AHI). The relationships between rs2576178 and rs10887800 and the risk of hypertension were evaluated using the binary logistic regression, and haplotype analysis. Results: In the bottom AHI quartile, rs10887800 was significantly associated with the risk of hypertension according to the dominant model [odds ratio(OR)=0.691, 95% confidence interval (CI)=0.483-0.990, P=0.044] even after adjustment for age, sex, and the body mass index. The G-A haplotype was associated with a co-effect of the two SNPs, namely, the risk of hypertension decreased (OR=0.879, 95%CI=0.784-0.986, P=0.028). Conclusions: We find no association between single rs2576178 or rs10887800 variants with the risk of hypertension in our OSA population. But, the synergistic effect of the two polymorphisms is associated with the risk of hypertension in OSA patients.

Abstract
PURPOSE/OBJECTIVE(S) To retrospectively investigate the safety and efficacy of radiotherapy combined with systemic chemotherapy for recurrent metastatic renal pelvic and ureteral carcinoma. MATERIALS/METHODS A total of 109 patients were enrolled in this study, including 44 patients in the Radio-chemotherapy group and 65 patients in the Chemotherapy group. Propensity score matching (PSM) was used to balance the clinical baseline characteristics of the two groups by 1:1 matching. Kaplan-Meier method was used to calculate progression-free survival (PFS) and overall survival (OS) before and after matching. Prognostic factors were analyzed by Cox proportional risk model. Treatment-related adverse events were graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. RESULTS The median follow-up time was 14.5 months. Multivariate analysis showed that radiotherapy was a good independent prognostic factor for OS in patients with recurrent metastatic renal pelvic and ureteral carcinoma (HR: 0.327, 95% CI: 0.157∼0.680, P = 0.003). After matching, there were 40 patients in the Radio-chemotherapy group and 40 patients in the Chemotherapy group, and the median PFS and median OS in the Radio-chemotherapy group were better than those in the Chemotherapy group (PFS: 10.4 months vs. 6.7 months, P = 0.035; OS: 43.5 months vs. 18.8 months, P<0.001). The 1-year OS and 2-year OS of the Radio-chemotherapy group were higher than those of the Chemotherapy group (1-year OS: 88.1% vs. 70.4%; 2-year OS: 81.1% vs. 39.3%). In addition, in the Radio-chemotherapy group, patients treated with radiotherapy before first-line chemotherapy failure had longer PFS than those treated with radiotherapy after chemotherapy failure (median PFS: 15.7 months vs. 6 months, P = 0.003). There was no significant difference in the incidence of grade 3∼4 toxicities between the Radio-chemotherapy group and the Chemotherapy group (52.3% vs. 50.8%, P = 0.878). CONCLUSION For patients with advanced renal pelvic and ureteral carcinoma, adding radiotherapy on the basis of systemic chemotherapy is well tolerable and expected to bring long-term survival benefits to patients, and the benefits of early interventional radiotherapy may be more obvious.

Abstract
PURPOSE/OBJECTIVE(S) Gleason grade group 5 (GG5) prostate cancers is aggressive with high metastatic rates and is not sensitive to androgen deprivation therapy (ADT). Even the presence of a limited (tertiary) Gleason pattern 5 component may have high aggressive biological behavior. This study aims to prospectively evaluate whether a non-androgen receptor pathway therapy - adjuvant chemotherapy could improve clinical outcomes among non-metastatic prostate cancer with the above highly malignant characters. MATERIALS/METHODS This prospective non-randomized clinical trial included non-metastatic prostate cancer patients with pathologically proven Gleason score of 9-10 or tertiary Gleason pattern 5. Each subject was allowed to decide whether to receive four to six cycles chemotherapy of docetaxel after receiving a standard treatment (i.e., radical surgery ± radiotherapy or radical radiotherapy combined with long-term ADT). The primary endpoint was event-free survival (EFS). Event was defined as any of biochemical failure or imaging failure, or change of systemic therapy due to PSA arises, or death. The secondary end points were distant metastasis-free survival (MFS), overall survival (OS), and treatment-related adverse events. RESULTS A total of 188 consecutive patients were enrolled from November 2019 to November 2022. Median prostate-specific antigen was 26.6 ng/ml. 52% had T3b to T4 disease, 27% had N1 disease. 140 patients received standard therapy only, and 48 patients received adjuvant chemotherapy after radical therapy. The median follow-up time was 18.4 (3.0-36.7) months. The estimated 36-month EFS of the chemotherapy group and the control group were 94.7% vs. 72.8% (p = 0.044). There were 1 event who added novel endocrine therapy in the chemotherapy group, and 21 events in the control group, including 6 cases of biochemical recurrence and 9 cases of lymph node and distant metastasis, 4 cases that changed systemic therapy and 2 cases died. The MFS of the two groups at 36 months were 100% and 90.7%, respectively (P = 0.143). After the 1:1 propensity score match, the EFS and MFS of the two groups were 94.7% and 80.8% (P = 0.069), and 100% and 93.1% (P = 0.132), respectively. The urinary toxicity of grade 2 and 3 in the chemotherapy group and the control group were 4.2% and 7.1% (P = 0.134) while the grade 2 rectal toxicity were 5.0% and 10.4% (P = 0.317), respectively. No grade 4 toxicity occurred. Considering the chemotherapy-related side effects, grade 3 or above toxicity were leukopenia (41.7%), alopecia (27.1%), thrombocytopenia (2.1%) and edema (2.1%). CONCLUSION Results of this interim analysis shows that the addition of adjuvant chemotherapy after standard radical therapy tends to improve the overall recurrence and metastasis free survival of patients with highly malignant prostate cancer, and the adverse effects are tolerable, which should be confirmed by long-term follow-up results.

Abstract
Objective: To observe the status of patient-reported outcomes (PROs) and their correlation with the number of hospitalizations within 1 year in patients with atrial fibrillation(AF). Methods: This study is a prospective investigation. Patients with non-valvular atrial fibrillation treated in the Department of Cardiology of the Third People's Hospital of Yancheng from May 2020 to April 2021 were selected. General information and AF6 questionnaire were used to define PROs. The number of hospitalizations within 1 year after discharge was obtained. Spearman correlation analysis was used to analyze the correlation between PROs and the New York Heart Association (NYHA) classification. The logistic regression model was used to analyze the number of hospitalizations in AF patients within 1 year. Results: A total of 197 patients were enrolled, the mean age was (74.1±9.0) years, 106 (53.8%) patients were female. The mean AF6 score was (24.3±8.3). The proportion of patients with 6 entries≥1 point exceeded 50%. There was a positive correlation between NYHA classification and PROs (r=0.360, P<0.001). Logistic regression analysis showed that the older age (OR=1.058, P=0.004) and the AF6 scores≥24(OR=4.082, P<0.001) were the risk factors of rehospitalization within 1 year for AF patients. Conclusions: The PROs of AF patients are at the medium level and poor levels of PROs are associated with increased risk of rehospitalization within 1 year.

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
Nonalcoholic fatty liver disease (NAFLD) is a chronic metabolic stress liver injury due to chronic malnutrition in genetically susceptible individuals. With the prevalence of obesity, diabetes, and metabolic syndrome, NAFLD has become the world's number one chronic liver disease, and the flaws of forty years of exclusive disease diagnostic criteria and stigmatized disease terminology are becoming increasingly prominent. To this end, in the past three years, the international consensus group and the three major hepatology societies have suggested that NAFLD be renamed metabolism-associated fatty liver disease (MAFLD) and metabolism-associated steatosis liver disease (MASLD). Here is a description of the background of naming NAFLD, MAFLD, and MASLD, the similarities and differences of the three terms, the existing disputes, and our country's coping strategies.

Abstract
INTRODUCTION Psittacosis can cause severe community-acquired pneumonia (CAP). The clinical manifestations of psittacosis range from subclinical to fulminant psittacosis with multi-organ failure. It is essential to summarize the clinical characteristic of patients with severe psittacosis accompanied by acute hypoxic respiratory failure (AHRF). METHODS This retrospective study included patients with severe psittacosis caused CAP accompanied by AHRF from 19 tertiary hospitals of China. We recorded the clinical data, antimicrobial therapy, respiratory support, complications, and outcomes. Chlamydia psittaci was detected on the basis of metagenomic next-generation sequencing performed on bronchoalveolar lavage fluid samples. Patient outcomes were compared between the treatment methods. RESULTS This study included 45 patients with severe CAP and AHRF caused by psittacosis from April 2018 to May 2021. The highest incidence of these infections was between September and April. There was a history of poultry contact in 64.4% of the patients. The median PaO2/FiO2 of the patients was 119.8 (interquartile range, 73.2 to 183.6) mmHg. Four of 45 patients (8.9%) died in the ICU, and the median ICU duration was 12 days (interquartile range, 8 to 21) days. There were no significant differences between patients treated with fluoroquinolone initially and continued after the diagnosis, fluoroquinolone initially followed by tetracycline, and fluoroquinolone combined with tetracycline. CONCLUSION Psittacosis caused severe CAP seems not rare, especially in the patients with the history of exposure to poultry or birds. Empirical treatment that covers atypical pathogens may benefit such patients, which fluoroquinolones might be considered as an alternative.

Abstract
Objective: To explore the association of different obesity measurement indexes on serum C-reactive protein (CRP) in Chinese adult women. Methods: The data were obtained from baseline and follow-up surveys of the urban Breast Cancer Screening Program in Shuangliu District, Chengdu. A total of 441 adult women were included in the study. A questionnaire survey, physical examination, and laboratory testing were conducted on the subjects. Multivariate logistic regression model, two-level mixed effects logistic regression model, and restricted cubic spline method were used to investigate the linear and nonlinear correlation between different obesity measurement indexes and serum CRP in adult women. Results: For every 1 unit increase in BMI, waist circumference (WC), and adiposity, the risk of elevated serum CRP or exacerbation of chronic low-grade inflammation in adult women increased by 16.5%, 5.0%, and 11.1% (P<0.05), respectively. Both BMI and adiposity were nonlinear correlated with serum CRP. Using BMI=24.0 kg/m2 as the reference point, serum CRP level increased with the increase of BMI when BMI >24.0 kg/m2. Using adiposity=30% as the reference point, serum CRP level increased with the increase of adiposity when adiposity >30%. Conclusions: Overall, obesity reflected by BMI had the strongest association with serum CRP in adult women, followed by body fat content reflected by adiposity, and central obesity reflected by WC had the weakest association with CRP. Adult women with BMI >24.0 kg/m2 or adiposity >30% are at high risk for obesity-related inflammatory manifestations.

Abstract
Objective: To explore the influence of pH value on tube formation of human dermal microvascular endothelial cells (HDMECs) and study its molecular mechanism, so as to provide theoretical basis for the study of promoting angiogenesis in the process of wound healing. Methods: The experimental study methods were applied. HDMECs of 4 or 5 passages in the logarithmic growth phase were collected for experiments. Culture mediums with pH values of 6.4, 6.6, 6.8, 7.0, 7.2, 7.4, 7.6, and 7.8 were prepared, and the cells were adaptively cultured (the same culture method below) for 24 h before further experiments being carried out. After another 36 h of culture, the relative fluorescence value of cytoplasmic pH value was measured by flow cytometry, and the correlation analysis between the relative fluorescence value of cytoplasmic pH value and the medium pH value was carried out. After another 1.5, 2.5, 3.5, 4.5, and 5.5 days of culture, the cell proliferation activity was detected with cell counting kit 8. OrisTM cell migration detection kit was used to detect the remaining area of cell migration at 0 (immediately), 24, and 48 h after removing the cell seeding stopper. Three-dimensional stromal gel cell tube formation experiment was carried out to detect the lumen diameter of tube formed by cells after another 48 h of culture. The protein expressions of phosphorylation sites 473 and 308 of protein kinase B (Akt) were detected by Western blotting after another 48 h of culture. The sample number was 3. Data were statistically analyzed with Pearson correlation analysis, one-way analysis of variance, analysis of variance for factorial design, analysis of variance for repeated measurement, and Bonferroni correction. Results: After another 36 h of culture, the relative fluorescence values of cytoplasmic pH value of cells cultured in pH 6.8-7.8 mediums were significantly higher than the level in pH 6.4 medium (P<0.05); compared with those in pH 6.6-7.0 mediums, the relative fluorescence values of cytoplasmic pH value of cells cultured in pH 7.4-7.8 mediums were significantly increased (P<0.05), and the relative fluorescence value of cytoplasmic pH value of cells cultured in pH 6.6 medium was significantly lower than that in pH 7.0 or 7.2 mediun (with P values all <0.05); the relative fluorescence values of cytoplasmic pH value of cells cultured in pH 7.6 and 7.8 mediums were significantly higher than those in pH 7.2 and 7.4 mediums (P<0.05). The relative fluorescence value of cytoplasmic pH value was significantly positively correlated with the medium pH value (r=0.99, P<0.05). The proliferation activity was similar among cells cultured in 8 mediums of different pH values for another 1.5 days (P>0.05). After another 2.5 days of culture, the proliferation activity of cells cultured in pH 6.4-6.8 mediums was significantly decreased compared with that in pH 7.6 medium (P<0.05). After another 3.5 days of culture, the proliferation activity of cells cultured in pH 7.0-7.8 mediums was significantly higher than that in pH 6.4-6.8 mediums (P<0.05); compared with that in pH 7.6 medium, the proliferation activity of cells cultured in pH 7.0-7.4 and 7.8 mediums was significantly decreased (P<0.05). After another 4.5 or 5.5 days of culture, the proliferation activity of cells cultured in pH 6.8-7.8 mediums was significantly higher than that in pH 6.4 medium (P<0.05); compared with that in pH 6.6 and 6.8 mediums, the proliferation activity of cells cultured in pH 7.0-7.8 mediums was significantly increased (P<0.05). After another 4.5 days of culture, the proliferation activity of cells cultured in pH 7.6 medium was significantly higher than that in pH 7.0 medium (P<0.05). After another 5.5 days of culture, the proliferation activity of cells cultured in pH 7.2-7.6 mediums was significantly increased compared with that in pH 7.0 medium (P<0.05); the proliferation activity of cells cultured in pH 7.2 and 7.4 mediums was significantly lower than that in pH 7.6 medium (with P values all <0.05) but significantly higher than that in pH 7.6 medium (with P values all <0.05). Immediately after removing the cell seeding stopper, the remaining migration areas were similar among cells cultured in 8 mediums of different pH values (P>0.05). At 24 h after removing the cell seeding stopper, the remaining migration areas of cells cultured in pH 6.6-7.8 mediums were significantly smaller than the area in pH 6.4 medium (P<0.05); compared with those in pH 6.6 and 6.8 mediums, the remaining migration areas of cells cultured in pH 7.0 to 7.6 mediums were significantly reduced (P<0.05). At 48 h after removing the cell seeding stopper, compared with those in pH 6.4 and 6.6 mediums, the remaining migration areas of cells cultured in pH 7.0-7.8 mediums were significantly reduced (P<0.05); the remaining migration areas of cells cultured in pH 7.2 and 7.4 mediums were significantly smaller than those in pH 6.8, 7.0, and 7.8 mediums (P<0.05) but significantly larger than the area in pH 7.6 medium (P<0.05); the remaining migration area of cells cultured in pH 7.6 medium was significantly smaller than that in pH 6.8 or 7.8 medium (with P values all <0.05). After another 48 h of culture, the lumen diameters of tubes formed by cells cultured in pH 7.0, 7.2, 7.4, 7.6, and 7.8 mediums were (5.0±0.5), (7.6±0.9), (8.5±0.7), (11.0±0.8), and (5.3±0.8) μm, respectively, which were significantly longer than (2.8±0.8) μm in pH 6.4 medium (P<0.05); the lumen diameters of tubes formed by cells cultured in pH 6.6 ((4.2±0.3) μm), 6.8 ((4.5±0.6) μm), 7.0, and 7.8 mediums were significantly shorter than the diameter in pH 7.6 medium (P<0.05). After another 48 h of culture, compared with those in pH 6.4 and 6.6 mediums, the protein expressions of Akt phosphorylation sites 473 and 308 of cells cultured in pH 6.8 to 7.8 mediums were significantly increased (P<0.05). Moreover, the protein expression of Akt phosphorylation site 308 of cells cultured in pH 6.6 medium was significantly higher than that in pH 6.4 medium (P<0.05); compared with the expression in pH 6.8 medium, the protein expressions of Akt phosphorylation site 473 of cells cultured in pH 7.0 and 7.4-7.8 mediums were significantly increased (P<0.05); compared with the expression in pH 7.6 medium, the protein expressions of Akt phosphorylation site 473 of cells cultured in pH 7.0-7.4 and 7.8 mediums were significantly decreased (P<0.05); compared with the expression in pH 7.8 medium, the protein expressions of Akt phosphorylation site 308 of cells cultured in pH 7.0 to 7.6 mediums were significantly increased (P<0.05). Conclusions: pH value can regulate the lumen diameter of HDMEC-formed capillaries, which is closely related to the activation of Akt. 7.2-7.6 is the appropriate pH value for constructing tissue engineered capillaries.

Abstract
Objective: To investigate the spontaneous nystagmus (SN) and the frequency characteristics of affected semicircular canals in patients with vestibular neuritis (VN). Methods: This is a cross-sectional study. A total of 61 patients with VN admitted to the Department of Neurology of Shanxi Bethune Hospital from June 2020 to October 2021, 39 were male and 22 were female, with a mean age of (46±13) years old and male to female ratio of 1.77∶1. According to SN characteristics, 61 patients were divided into non-nystagmus group(nSN), horizontal nystagmus group(hSN) and horizontal-torsional nystagmus group (htSN). Clinical data were collected, and SN, unilateral weakness (UW), directional preponderance (DP), and video head impulse test (vHIT) gain were used as observation indicators. Statistical analysis by SPSS23.0 software. Normal distributed quantitative data (age, semicircular canal gain, SN intensity) were expressed by x¯±s, non-normal distributed quantitative data (disease course, UW, DP) were expressed by M(Q1,Q3), qualitative data were expressed by rate and composition ratio, difference analysis by one-way ANOVA, rank sum test, Chi-square test or Fisher's exact probability method, considered by P value<0.05. Results: (1)The disease course of nSN, hSN and htSN was 7.0 (4.0, 12.5), 6.0 (3.5, 11.5), and 3.0 (2.0, 6.5) days respectively, and there were statistical differences (χ2=7.31,P=0.026).(2)The horizontal nystagmus intensity of htSN was (16.8±8.6)°/s, which was significantly higher than that of (9.8±4.7)°/s in hSN (t=3.71, P<0.001). There was no significant difference in the positive rate of UW between the three groups (P=0.690), and there was a significant difference in the positive rate of DP in the three groups (χ2=12.23, P=0.002). The horizontal nystagmor intensity in the htSN was positively correlated with the vertical nystagmus intensity (r=0.59, P=0.001).(3)The gain of the affected horizontal canal of the three groups was statistically different (F=8.28, P=0.001), and the gain of the horizontal canal of hSN and htSN was significantly lower than that of nSN (t=2.74, P=0.008; t=4.05, P<0.001); The gain of the affected anterior canal in the three groups was statistically different (F=5.32, P=0.008). The gain of the anterior canal in both nSN and hSN was significantly higher than that in htSN (t=3.09, P=0.003; t=2.15, P=0.036). The horizontal canal gain of htSN is positively correlated with the anterior canal gain (r=0.74, P<0.001).(4)The affected semicircular canals in the two groups with no-vertical-component nystagmus (nSN and hSN) and the htSN were counted. The composition ratio of the affected semicircular canals in the two groups was different (χ2=8.34, P=0.015). Conclusion: The occurrence of SN in patients with VN is related to many factors, such as the disease course, low and high frequencies, and the severity of the condition in the affected semicircular canal.

Abstract
Objective: To investigate the effects of polyetheretherketone, zirconium dioxide, and titanium abutment materials on the expression of genes and proteins related to hemidesmosome adhesion in human gingival epithelial cells, in order to screen out abutment materials that are easier for epithelial adhesion. Methods: Forty-eight specimens were prepared in each of the three materials, polyetheretherketone, zirconium oxide, and pure titanium specimens. The surface morphology of each group of specimens was observed by scanning electron microscopy, the surface roughness was measured by the white light interferometer, and the contact angle was measured by optical contact angle measuring instrument. The early adhesion status of human gingival epithelial cells on the surface of each group of specimens was observed by scanning electron microscopy, and the proliferation ability of human gingival epithelial cells on the surface of each group of specimens was assessed by using a cell counting kit, and the expression levels of genes and proteins related to the adhesion of human gingival epithelial cells on the surface of each group of specimens were detected by real-time fluorescence quantitative PCR and Western blotting, respectively. Results: The surface morphology of the three groups of specimens was flat and smooth. The mean roughness (Ra value) of the polyetheretherketone, zirconia, and pure titanium groups were (95.63±2.06), (37.93±3.56), and (134.2±4.62) nm (F=368.16, P<0.001), respectively, and the mean maximum height (Rz value) was (2.42±0.22), (0.87±0.10) and (3.77±0.28) nm (F=91.95, P<0.001), with statistical significance (P<0.05). The contact angles were 81.23°±0.91°, 82.08°±2.10°, and 80.47°±1.85°, respectively, with no statistically significant overall difference (F=0.45, P=0.658). Human gingival epithelial cells showed irregular shapes such as flattened and extended polygons and polygons on the surface of the three groups of specimens, exhibiting a typical paving stone pattern. The differences in cell proliferation among the three groups at 1 and 3 d of culture were not statistically significant (P>0.05). Cell proliferation in the polyetheretherketone group was significantly greater those those in the zirconia and pure titanium groups at 5 and 7 d of culture (P<0.05). The mRNA expression levels and protein expression levels of laminin α3, integrin β4, and collagen ⅩⅦ in the polyetheretheretherketone group at 3 and 7 d of incubation were significantly greater than those in the zirconium oxide and pure titanium groups at the same time points (P<0.05). Conclusions: Polyetheretherketone is more conducive to the adhesion of hemidesmosome in human gingival epithelial cells than zirconium dioxide and pure titanium abutment materials.

Abstract
Statins are a kind of prescription drug that is widely used to treat hyperlipidemia, coronary artery disease, and other atherosclerotic diseases. A common side effect of statin use is a mild rise in liver aminotransferases, which occurs in less than 3% of patients. Statin-related liver injury is most commonly caused by atorvastatin and simvastatin, but severe liver injury is uncommon. Therefore, understanding and evaluating hepatotoxicity and weighing the benefits and risks is of great significance to better realize the protective effect of statins.

Abstract
Objective: To preliminarily analyze the application experience of veno-arterio-venous extracorporeal membrane oxygenation (VAV-ECMO).The VAV-ECMO is a rescue strategy for patients with extremely critical respiratory failure combined with refractory shock. Methods: From February 2016 to February 2022, the characteristics and outcomes of patients who were started on either veno-venous or veno-arterial ECMO due to respiratory or hemodynamic failure, and then converted to VAV-ECMO in respiratory intensive care unit (ICU) of Beijing Chaoyang Hospital were analyzed. Results: A total of 15 patients underwent VAV-ECMO, aged 53 (40, 65) years, and 11 of whom were male. Within the group, VV-ECMO was initially used in 12 patients due to respiratory failure, but then VAV-ECMO was used due to cardiogenic shock (7/12) and septic shock (4/12), while VAV-ECMO was established in two patients due to lung transplantation. One patient was diagnosed with pneumonia complicated by septic shock, which was initially determined to be VA-ECMO, but then switched to VAV-ECMO because it was difficult to maintain oxygenation. The time from the establishment of VV or VA-ECMO to the switch to VAV-ECMO was 3 (1, 5) days and the VAV-ECMO support time was 5 (2, 8) days. ECMO-related complications were bleeding, mostly in the digestive tract (n=4) and airway hemorrhage (n=4), without intracranial hemorrhage, and poor arterial perfusion of the lower limbs (n=2). Among these 15 patients, the overall ICU mortality was 53.3%. The mortality of patients who received VAV-ECMO due to septic shock and cardiogenic shock was 100% (4/4) and 42.8% (3/7), respectively. Two patients who received VAV-ECMO due to lung transplantation all survived. Conclusion: VAV-ECMO may be a safe and effective treatment for carefully selected patients with critical respiratory failure associated with cardiogenic shock or end-stage lung disease lung transplantation transition, however, patients with septic shock may benefit the least.

Abstract
BACKGROUND AND PURPOSE Ultrasound-guided radiofrequency ablation has been recommended as an alternative to surgery for benign thyroid nodules. However, little is known about the benefit from the application of radiofrequency ablation for benign thyroid nodules in elderly patients. The purpose of this study was to compare the clinical outcomes of radiofrequency ablation versus thyroidectomy for elderly patients with benign thyroid nodules. MATERIALS AND METHODS This retrospective study evaluated 230 elderly patients (60 years of age or older) with benign thyroid nodules treated with radiofrequency ablation (R group, n = 49) or thyroidectomy (T group, n = 181). Complications, thyroid function, and treatment variables, including procedural time, estimated blood loss, hospitalization, and cost, were compared after propensity score matching. The volume, volume reduction rate, symptoms, and cosmetic score were also evaluated in the R group. RESULTS After 1:1 matching, each group had 49 elderly patients. The rate of overall complications and hypothyroidism was 26.5% and 20.4% in the T group, respectively, but these complications were totally absent from the R group (P < .001, P = .001). Patients in the R group had a significantly shorter procedural time (median, 4.8 versus 95.0 minutes, P < .001) and lower cost (US $1979.02 versus US $2208.80, P = .013) than those treated by thyroidectomy. After radiofrequency ablation, the volume reduction rate was 94.1%, and 12.2% of nodules had completely disappeared. The symptom and cosmetic scores were both significantly reduced at the last follow-up. CONCLUSIONS Radiofrequency ablation could be considered as a first-line treatment for elderly patients with benign thyroid nodules.

Abstract
Objective: To investigate the response characteristics of patients with locally advanced/metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) treated with tislelizumab in combination with chemotherapy in the first line. Methods: Patients with nsq-NSCLC who achieved complete or partial remission after treatment with tislelizumab in combination with chemotherapy or chemotherapy alone in the RATIONALE 304 study, as assessed by an independent review board, were selected to analyze the response characteristics and safety profile of the responders. Time to response (TTR) was defined as the time from randomization to the achievement of first objective response. Depth of response (DpR) was defined as the maximum percentage of tumor shrinkage compared with the sum of the baseline target lesion length diameters. Results: As of January 23, 2020, 128 patients treated with tislelizumab in combination with chemotherapy achieved objective tumor response (responders), representing 57.4%(128/223) of the intention-to-treat population, with a TTR of 5.1 to 33.3 weeks and a median TTR of 7.9 weeks. Of the responders (128), 50.8%(65) achieved first remission at the first efficacy assessment (week 6), 31.3%(40) at the second efficacy assessment (week 12), and 18.0%(23) at the third and subsequent tumor assessments. The percentages of responders who achieved a depth of tumor response of 30% to <50%, 50% to <70% and 70% to 100% were 45.3%(58/128), 28.1%(36/128) and 26.6%(34/128), respectively, with median progression-free survival (PFS) of 9.0 months (95% CI: 7.7 to 9.9 months), 11.5 months (95% CI: 7.7 months to not reached) and not reached (95% CI: 11.8 months to not estimable), respectively. Tislelizumab plus chemotherapy were generally well tolerated in responders with similar safety profile to the overall safety population. Conclusion: Among responders to tislelizumab in combination with chemotherapy for nsq-NSCLC, 82.0%(105/128) achieves response within the first two tumor assessments (12 weeks) and 18.0%(23/128) achieves response at later (18 to 33 weeks) assessments, and there is a trend toward prolonged PFS in responders with deeper tumor response.

Abstract
Objective: To investigate the risk factors and treatment outcome of persistent inflammation-immunosuppression-catabolism syndrome (PICS) in patients with extensive burns. Methods: A retrospective case series study was conducted. From January 2017 to December 2021, 220 patients with extensive burns who were admitted to Guangzhou Red Cross Hospital of Jinan University met the inclusion criteria, including 168 males and 52 females, aged 18-84 (43±14) years. According to the occurrence of PICS, the patients were divided into PICS group (84 patients) and non-PICS group (136 patients). The general data such as sex, age, complication of underlying diseases and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on admission, sepsis-related organ failure evaluation (SOFA) scores on admission and 14 days post admission, and proportion of patients with mechanical ventilation over 48 h during treatment, special conditions such as total burn area, full-thickness burn area, proportion of patients admitted within 48 h post injury, and exposed deep wound area at the 30th day post injury, outcome indicators such as hospitalization day, total cost of hospital stay, number of surgeries, and death of patients in the 2 groups were collected and analyzed. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, and chi-square test. The multivariate logistic regression analysis was performed on the indicators with statistically significant differences between the two groups except for outcome indicators, and the independent risk factors influencing secondary PICS in patients with extensive burns were screened. Results: The APACHE Ⅱ and SOFA scores on admission, and proportion of patients with mechanical ventilation over 48 h during treatment of patients in PICS group were significantly higher than those in non-PICS group (t=6.78, Z=-4.75, χ2=4.74, respectively, P<0.05). There were no statistically significant differences in the rest of general data of patients between the two groups (P>0.05). The total burn area, full-thickness burn area, and exposed deep wound area at the 30th day post injury in PICS group were significantly greater than those in non-PICS group (t=6.29, Z=-7.25, Z=-8.73, P<0.05), the exposed deep wound areas at the 30th day post injury in PICS group and non-PICS group were respectively 25% (15%, 35%) total body surface area (TBSA) and 8% (0, 13%) TBSA, while the proportion of patients admitted within 48 h post injury was significantly lower than that in non-PICS group (χ2=6.13, P<0.05). The hospitalization day, total cost of hospital stay, and number of surgeries of patients in PICS group were significantly higher than those in non-PICS group (with Z values of -7.12, -8.48, and -6.87, respectively, P<0.05), while the deaths of patients in the 2 groups were similar (P>0.05). The APACHE Ⅱ score on admission and exposed deep wound area at the 30th day post injury both were the independent risk factors for PICS in patients with extensive burns (with odds ratios of 1.15 and 1.07, 95% confidence intervals of 1.06-1.25 and 1.05-1.10, respectively, P<0.05). Conclusions: The APACHE Ⅱ score on admission and exposed deep wound area at the 30th day post injury are the independent risk factors for PICS in patients with extensive burns. The patients with secondary PICS had good prognosis with more surgical intervention and hospitalization day, and higher total cost of hospital stay.

Abstract
OBJECTIVE To explore the protocol for diagnosing thyroid nodules based on core needle biopsy (CNB) and study the biomarkers' application in distinguishing indeterminate samples. METHODS Patients with thyroid nodules treated at Peking University First Hospital from 2015 to 2020 were reviewed. In the study, 598 cases with CNB and matched resected specimens were retrieved. According to "diagnostic categories of thyroid CNB" proposed by the Korean Endocrine Pathology Thyroid Core Needle Biopsy Study Group, the CNB samples were diagnosed as follows: Ⅰ, unsatisfactory; Ⅱ, benign; Ⅲ, indeterminate; Ⅳ, follicular neoplasm; Ⅴ, suspicious for malignancy; and Ⅵ, malignant. The samples of CNB Ⅲ were stained by immunohistochemistry (IHC) using antibodies against CK19, Galectin-3, HBME-1, and CD56, and detected by next-generation sequencing (NGS) using an OncoAim® thyroid cancer multigene assay kit (Singlera Genomics) that detected 26 genes. Taking the resected specimens' classification as the gold standard, the predictive value of CNB for determining the malignancy of thyroid nodules and the biomarkers for distinguishing the samples of CNB Ⅲ was calculated. RESULTS The study included 598 patients, of which none were CNB Ⅰ, 40 cases were CNB Ⅱ, 40 cases were CNB Ⅲ, 32 cases were CNB Ⅳ, 35 cases were CNB Ⅴ, and 451 cases were CNB Ⅵ. The predictive value of CNB Ⅳ for determining follicular neoplasm was sensitivity (Sen) 100.00% and specificity (Sep) 100.00%, CNB Ⅴ-Ⅵ for determining malignancy was Sen 94.55% and Sep 100.00%, CNB Ⅱ for determining benign lesions was Sen 75.00% and Sep 99.80%. The predictive value of biomarkers for determining malignancy in cases of CNB Ⅲ was Sen 96.30% and Sep 92.31% by NGS, and Sen 81.48% and Sep 92.30% by IHC. CONCLUSION The Korean "diagnostic categories of thyroid CNB", which considers the histological specificity of CNB samples and the habits of clinicians, have strong operability, high diagnosis rate, and high clinical value. Under this framework, the cases of CNB Ⅵ should be treated with surgical operation, the cases of CNB Ⅴ-Ⅵ are recommended to be treated as malignant neoplasms, and the major cases of CNB Ⅱ could be followed up without worrisome except the one considered malignant by ultrasound. The value of biomarkers in distinguishing the cases of CNB Ⅲ is significant.

Measurement of the ^{18}O(α, γ)^{22}Ne Reaction Rate at JUNA and Its Impact on Probing the Origin of SiC Grains. PHYSICAL REVIEW LETTERS 2023; 130:092701.

Abstract
The ^{18}O(α,γ)^{22}Ne reaction is critical for AGB star nucleosynthesis due to its connection to the abundances of several key isotopes, such as ^{21}Ne and ^{22}Ne. However, the ambiguous resonance energy and spin-parity of the dominant 470 keV resonance leads to substantial uncertainty in the ^{18}O(α,γ)^{22}Ne reaction rate for the temperature of interest. We have measured the resonance energies and strengths of the low-energy resonances in ^{18}O(α,γ)^{22}Ne at the Jinping Underground Nuclear Astrophysics experimental facility (JUNA) with improved precision. The key 470 keV resonance energy has been measured to be E_{α}=474.0±1.1 keV, with such high precision achieved for the first time. The spin-parity of this resonance state is determined to be 1^{-}, removing discrepancies in the resonance strengths in earlier studies. The results significantly improve the precision of the ^{18}O(α,γ)^{22}Ne reaction rates by up to about 10 times compared with the previous data at typical AGB temperatures of 0.1-0.3 GK. We demonstrate that such improvement leads to precise ^{21}Ne abundance predictions, with an impact on probing the origin of meteoritic stardust SiC grains from AGB stars.

Abstract
Objective: To fabricate TiO2 nanotube material functionalized by antimicrobial peptide LL-37, and to explore its effects on biological behaviors such as adhesion and migration of human keratinocytes (HaCaT) and its antibacterial properties. Methods: The TiO2 nanotube array (NT) was constructed on the surface of polished titanium (PT) by anodization, and the antimicrobial peptide LL-37 was loaded on the surface of TiO2 nanotube (LL-37/NT) by physical adsorption. Three samples were selected by simple random sampling in each group. Surface morphology, roughness, hydrophilicity and release characteristics of LL-37 of the samples were analyzed with a field emission scanning electron microscope, an atomic force microscope, a contact angle measuring device and a microplate absorbance reader. HaCaT cells were respectively cultured on the surface of three groups of titanium samples. Each group had 3 replicates. The morphology of cell was observed by field emission scanning electron microscope. The number of cell adhesion was observed by cellular immunofluorescence staining. Cell counting kit-8 (CCK-8) assay was used to detect cell proliferation. Wound scratch assay was used to observe the migration of HaCaT. The above experiments were used to evaluate the effect of each group on the biological behavior of HaCaT cells. To evaluate their antibacterial effects, Porphyromonas gingivalis (Pg) was respectively inoculated on the surface of three groups of titanium samples. Each group had 3 replicates. The morphology of bacteria was observed by field emission scanning electron microscope. Bacterial viability was determined by live/dead bacterial staining. Results: A uniform array of nanotubes could be seen on the surface of titanium samples in LL-37/NT group, and the top of the tube was covered with granular LL-37. Compared with PT group [the roughness was (2.30±0.18) nm, the contact angle was 71.8°±1.7°], the roughness [(20.40±3.10) and (19.10±4.11) nm] and hydrophilicity (the contact angles were 22.4°±3.1° and 25.3°±2.2°, respectively) of titanium samples increased in NT and LL-37/NT group (P<0.001). The results of in vitro release test showed that the release of antimicrobial peptide LL-37 was characterized by early sudden release (1-4 h) and long-term (1-7 d) slow release. With the immunofluorescence, more cell attachment was found on NT and LL-37/NT than that on PT at the first 0.5 and 2.0 h of culture (P<0.05). The results of CCK-8 showed that there was no significant difference in the proliferation of cells among groups at 1, 3 and 5 days after culture. Wound scratch assay showed that compared with PT and NT group, the cell moved fastest on the surface of titanium samples in LL-37/NT group at 24 h of culture [(96.4±4.9)%] (F=35.55, P<0.001). A monolayer cells could be formed and filled with the scratch in 24 h at LL-37/NT group. The results of bacterial test in vitro showed that compared with the PT group, the bacterial morphology in the NT and LL-37/NT groups was significantly wrinkled, and obvious bacterial rupture could be seen on the surface of titanium samples in LL-37/NT group. The results of bacteria staining showed that the green fluorescence intensity of titanium samples in LL-37/NT group was the lowest in all groups (F=66.54,P<0.001). Conclusions: LL-37/NT is beneficial to the adhesion and migration of HaCaT cells and has excellent antibacterial properties, this provides a new strategy for the optimal design of implant neck materials.
