Abstract
BACKGROUND Delayed gastric emptying (DGE) commonly occurs after pancreaticoduodenectomy (PD). Risk factors for DGE have been reported in open PD but are rarely reported in laparoscopic PD (LPD). This study was designed to evaluate the perioperative risk factors for DGE and secondary DGE after LPD in a single center. METHODS This retrospective cohort study included patients who underwent LPD between October 2014 and April 2023. Demographic data, preoperative, intraoperative, and postoperative data were collected. The risk factors for DGE and secondary DGE were analyzed. RESULTS A total of 827 consecutive patients underwent LPD. One hundred and forty-two patients (17.2%) developed DGE of any type. Sixty-five patients (7.9%) had type A, 62 (7.5%) had type B, and the remaining 15 (1.8%) had type C DGE. Preoperative biliary drainage (p = 0.032), blood loss (p = 0.014), and 90-day any major complication with Dindo-Clavien score ≥ III (p < 0.001) were independent significant risk factors for DGE. Seventy-six (53.5%) patients were diagnosed with primary DGE, whereas 66 (46.5%) patients had DGE secondary to concomitant complications. Higher body mass index, soft pancreatic texture, and perioperative transfusion were independent risk factors for secondary DGE. Hospital stay and drainage tube removal time were significantly longer in the DGE and secondary DGE groups. CONCLUSION Identifying patients at an increased risk of DGE and secondary DGE can be used to intervene earlier, avoid potential risk factors, and make more informed clinical decisions to shorten the duration of perioperative management.

Abstract
Intervertebral disc degeneration (IDD) is one of the primary causes of low back pain (LBP), which seriously affects patients' quality of life. In recent years, interleukin (IL)-17 has been shown to be highly expressed in the intervertebral disc (IVD) tissues and serum of patients with IDD, and IL-17A has been shown to promote IDD through multiple pathways. We first searched databases such as PubMed, Cochrane, Embase, and Web of Science using the search terms "IL-17 or interleukin 17″ and "intervertebral discs". The search period ranged from the inception of the databases to December 2023. A total of 24 articles were selected after full-text screening. The main conclusion of the clinical studies was that IL-17A levels are significantly increased in the IVD tissues and serum of IDD patients. The results from the in vitro studies indicated that IL-17A can activate signaling pathways such as the NF-κB and MAPK pathways; promote inflammatory responses, extracellular matrix degradation, and angiogenesis; and inhibit autophagy in nucleus pulposus cells. The main finding of the in vivo experiments was that puncture of animal IVDs resulted in elevated levels of IL-17A within the IVD, thereby inducing IDD. Clinical studies, in vitro experiments, and in vivo experiments confirmed that IL-17A is closely related to IDD. Therefore, drugs that target IL-17A may be novel treatments for IDD, providing a new theoretical basis for IDD therapy.

Abstract
Splenectomy is an effective treatment for immune thrombocytopenia (ITP). The effect of COVID-19 vaccination on splenectomized patients with ITP during the COVID-19 pandemic has not been reported. Therefore, this study aimed to investigate the effect of COVID-19 vaccination on clinical outcomes in these patients. This was a longitudinal study of splenectomized patients with ITP. A total of 191 splenectomized patients were included in this study. After a median follow-up of 114 months, 146 (76.4%) patients had a sustained response to splenectomy. During COVID-19 infection, vaccinated patients showed a lower risk of severe infections (odds ratio [OR], 0.13; 95% confidence interval [CI]: 0.05-0.36; p < 0.001), hospitalization (OR, 0.13; 95% CI, 0.04-0.48; p = 0.002), and ITP exacerbation (OR, 0.16; 95% CI, 0.04-0.67; p = 0.012). These findings indicate that COVID-19 vaccination plays a protective role in splenectomized patients with ITP.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is not sensitive to most chemotherapy drugs, leading to poor chemotherapy efficacy. Recently, Trametinib and Palbociclib have promising prospects in the treatment of pancreatic cancer. This article aims to explore the effects of Trametinib on pancreatic cancer and address the underlying mechanism of resistance as well as its reversal strategies. The GDSC (Genomics of Drug Sensitivity in Cancer) and CTD2 (Cancer Target Discovery and Development) were utilized to screen the potential drug candidate in PDAC cell lines. The dose-increase method combined with the high-dose shock method was applied to induce the Trametinib-resistant PANC-1 and MIA PaCa-2 cell lines. The CCK8 proliferation assay, colony formation assay, flow cytometry, and western blot were conducted to verify the inhibitory effect of Trametinib and Palbociclib. RNA-seq was performed in resistant PDAC cell lines to find the differential expression genes related to drug resistance and predict pathways leading to the reversal of Trametinib resistance. The GDSC and CTD2 database screening revealed that Trametinib demonstrates a significant inhibitory effect on PDAC. We found that Trametinib has a lower IC50 than Gemcitabine in PDAC cell lines. Both Trametinib and Gemcitabine can decrease the proliferation capacity of pancreatic cells, induce cell cycle arrest, and increase apoptosis. Simultaneously, the phosphorylation of the AKT and ERK pathways were inhibited by the treatment of Trametinib. In addition, the RNA-seq of Trametinib-induced resistance PDAC cell lines reveals that the cyclin-dependent kinase (CDK)-RB-E2F regulatory axis and G2/M DNA damage checkpoint might lead the drug resistance. Besides, the combination of Trametinib with Palbociclib could inhibit the proliferation and cell cycle of both resistant cells lines and also restore the sensitivity of drug-resistant cells to Trametinib. Last but not least, the interferon-α and interferon-γ expression were upregulated in resistance cell lines, which might lead to the reversal of drug resistance. The study shows Trametinib has a critical inhibitory effect on PDAC. Besides, the combination of Trametinib with Palbociclib can inhibit the proliferation of PDAC-resistant cells.

Abstract
OBJECTIVE To investigate the effect of low-molecular-weight heparin (LMWH) on placenta-mediated fetal growth restriction (FGR). METHODS A cohort of 570 pregnant women diagnosed with placenta-mediated FGR were enrolled from January 1, 2015 through to December 31, 2021. A birth database, including demographic data, antenatal complications, and detailed delivery and newborn data, was created to collect variables from the Hospital Information System (HIS) Database. The unique personal registration number, assigned to each patient on first registration with HIS in the West China Second University Hospital, was used to link these patients. LMWH use was defined as at least 1-week prescription from diagnosis of placenta-mediated FGR. Pregnant women received LMWH (Enoxaparin 4000 IU/day) by self-administered subcutaneous injection only when they agreed and signed informed consent. Primary outcome was intrauterine fetal death after 20 weeks of pregnancy. Secondary outcomes included preterm birth (PB), Apgar score less than 7 at 1 min, admission to neonatal intensive care unit (NICU), and birth weight. Logistic regression analysis was conducted to compute adjusted odds ratio (aOR) with 95% confidence intervals (CI) for outcomes. RESULTS After controlling for confounders, LMWH use was associated with a decreased risk of intrauterine fetal death (aOR 2.49, 95% CI 1.35-4.57, P = 0.003), PB before 37 weeks of pregnancy (aOR 3.35, 95% CI 2.14-5.23, P < 0.001), PB before 34 weeks of pregnancy (aOR 2.25, 95% CI 1.36-3.74, P = 0.002), Apgar score less than 7 at 1 min (aOR 2.25, 95% CI 1.36-3.74, P = 0.002), NICU admission (aOR 2.29, 95% CI 1.48-3.55, P < 0.001). Using LMWH increased the mean birth weight in PB before 32 weeks of pregnancy (mean ± standard deviation [SD] 1126.4 ± 520.0 g, P = 0.020), PB before 37 weeks of pregnancy (mean ± SD 1563.9 ± 502.7 g, P = 0.019), early-onset FGR (mean ± SD 2125.2 ± 665.7 g, P < 0.001), late-onset FGR (mean ± SD 2343.4 ± 507.9, P < 0.001), and non-severe FGR (mean ± SD 2231.1 ± 607.2 g, P < 0.001). CONCLUSION Use of LMWH can significantly improve the fetal and neonatal outcomes among pregnant women with placenta-mediated FGR, particularly reducing the risk of intrauterine fetal death.

Abstract
BACKGROUND The fistula risk score (FRS) is the widely acknowledged prediction model for clinically relevant postoperative pancreatic fistula (CR-POPF). In addition, the alternative FRS (a-FRS) and updated alternative FRS (ua-FRS) have been developed. This study performed external validation and comparison of these 3 models in patients who underwent laparoscopic pancreaticoduodenectomy (LPD) with Bing's pancreaticojejunostomy. METHODS The FRS total points and predictive probabilities of a-FRS and ua-FRS were retrospectively calculated using patient data from a completed randomized controlled trial. Postoperative pancreatic fistula (POPF) and CR-POPF were defined according to the 2016 International Study Group of Pancreatic Surgery criteria. The correlations of the 4 risk items of the FRS model with CR-POPF and POPF were analyzed and represented using the Cramer V coefficient. The performance of the 3 models was measured using the area under the curve (AUC) and calibration plot and compared using the DeLong test. RESULTS This study enrolled 200 patients. Pancreatic texture and pathology had discrimination for CR-POPF (Cramer V coefficient: 0.180 vs 0.167, respectively). Pancreatic duct diameter, pancreatic texture, and pathology had discrimination for POPF (Cramer V coefficient: 0.357 vs 0.322 vs 0.257, respectively). Only the calibration of a-FRS predicting CR-POPF was good. The differences among the AUC values of the FRS, a-FRS, and ua-FRS were not statistically significant (CR-POPF: 0.687 vs 0.701 vs 0.710, respectively; POPF: 0.733 vs 0.741 vs 0.750, respectively). After recalibrating, the ua-FRS got sufficient calibration, and the AUC was 0.713 for predicting CR-POPF. CONCLUSION For LPD cases with Bing's pancreaticojejunostomy, the 3 models predicted POPF with better discrimination than predicting CR-POPF. The recalibrated ua-FRS had sufficient discrimination and calibration for predicting CR-POPF.

Abstract
To explore the mechanism whereby cGAS-STING pathway regulates the pyroptosis of cryptorchidism cells, with a view to finding a new strategy for clinically treating cryptorchidism-induced infertility. Spermatogonial GC-1 cells were heat stimulated to simulate the heat hurt microenvironment of cryptorchidism. The cell viability was assayed by CCK-8, and cellular DNA damage was detected by gamma-H2AX immunofluo-rescence assay. Flow cytometry was employed to assess pyroptosis index, while western blot, ELISA and PCR were used to examine the expressions of pyroptosis-related proteins (Caspase-1, IL-1beta, NLRP3) and cGAS-STING pathway proteins (cGAS, STING). After STING silencing by siRNA, the expressions of pyroptosis-related proteins were determined. Pyroptosis occurred after heat stimulation of cells. Morphological detection found cell swelling and karyopyknosis. According to the gamma-H2AX immunofluorescence (IFA) assay, the endonuclear green fluorescence was significantly enhanced, the gamma-H2AX content markedly increased, and the endonuclear DNA was damaged. Flow cytometry revealed a significant increase in pyroptosis index. Western blot and PCR assays showed that the expressions of intracellular pyrogenic proteins like Caspase-1, NLRP3 and GSDMD were elevated. The increased STING protein and gene expressions in cGAS-STING pathway suggested that the pathway was intracellularly activated. Silencing STING protein in cGAS-STING pathway led to significantly inhibited pyroptosis. These results indicate that cGAS-STING pathway plays an important role in heat stress-induced pyroptosis of spermatogonial cells. After heat stimulation of spermatogonial GC-1 cells, pyroptosis was induced and cGAS-STING pathway was activated. This study can further enrich and improve the molecular mechanism of cryptorchidism.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Neutrophil extracellular trap (NET) formation plays a crucial role in wound healing disorders, including chronic skin ulcers and diabetic foot ulcers (DFUs). Over the years, traditional Chinese topical medications, such as Cinnabar (composed of HgS and soluble mercury salt) and hydrargyria oxydum rubrum (containing HgO and soluble mercury salt), have been utilized for treating these ailments. Nevertheless, the fundamental processes remain mostly ambiguous. AIM OF THE STUDY This study sought to investigate the potential effects of topical mercury-containing preparations on the process of NET formation. MATERIALS AND METHODS Neutrophils isolated from healthy individuals and mouse models of type 1 and type 2 diabetes were cultured with phorbol 12-myristate 13-acetate (PMA), both with and without the mercury-containing preparations (MCP). The formation of NETs was monitored using confocal and scanning electron microscopes. Immunofluorescence and fluorescent probes were employed to assess the levels of citrulline histone H3 (Cit-H3) and intracellular reactive oxygen species (ROS), respectively. The impact of MCP extracts on cytokine expression, peptidylarginine deiminase 4 (PAD4), and myeloperoxidase (MPO) was measured through Luminex and ELISA assays. Phagocytosis of human neutrophils was analyzed using Flow Cytometry. Finally, the phosphorylation levels of ERK were detected by western blotting. RESULTS Treatment with MCP led to a reduction in PAD4, Cit-H3, and MPO expressions in neutrophils, consequently inhibiting PMA-induced NET formation. MCP treatment also dampened ERK1/2 activation in neutrophils. Furthermore, MCP exhibited inhibitory effects on the secretion of the cytokine IL-8 and ROS production while enhancing neutrophil phagocytosis. CONCLUSION Our findings suggest that MCP can mitigate the release of NETs, likely by suppressing the ERK1/2 signaling pathway.

Abstract
BACKGROUND Various surgical skills lead to differences in patient outcomes and identifying poorly skilled surgeons with constructive feedback contributes to surgical quality improvement. The aim of the study was to develop an algorithm for evaluating surgical skills in laparoscopic cholecystectomy based on the features of elementary functional surgical gestures (Surgestures). MATERIALS AND METHODS Seventy-five laparoscopic cholecystectomy videos were collected from 33 surgeons in five hospitals. The phase of mobilization hepatocystic triangle and gallbladder dissection from the liver bed of each video were annotated with 14 Surgestures. The videos were grouped into competent and incompetent based on the quantiles of modified global operative assessment of laparoscopic skills (mGOALS). Surgeon-related information, clinical data, and intraoperative events were analyzed. Sixty-three Surgesture features were extracted to develop the surgical skill classification algorithm. The area under the receiver operating characteristic curve of the classification and the top features were evaluated. RESULTS Correlation analysis revealed that most perioperative factors had no significant correlation with mGOALS scores. The incompetent group has a higher probability of cholecystic vascular injury compared to the competent group (30.8 vs 6.1%, P =0.004). The competent group demonstrated fewer inefficient Surgestures, lower shift frequency, and a larger dissection-exposure ratio of Surgestures during the procedure. The area under the receiver operating characteristic curve of the classification algorithm achieved 0.866. Different Surgesture features contributed variably to overall performance and specific skill items. CONCLUSION The computer algorithm accurately classified surgeons with different skill levels using objective Surgesture features, adding insight into designing automatic laparoscopic surgical skill assessment tools with technical feedback.

Abstract
BACKGROUND Textbook oncologic outcomes (TOO) have been used to evaluate long-term oncologic outcomes for patients after pancreaticoduodenectomy (PD) but not laparoscopic pancreaticoduodenectomy (LPD). The aim of the study was to assess the prognostic value of TOO for patients with pancreatic head cancer undergoing LPD and discuss the risk factors associated with achieving TOO. METHODS Patients with pancreatic head cancer who underwent LPD in West China Hospital from January 2015 to May 2022 were consecutively enrolled. TOO was defined as achieving R0 resection, examination of ≥ 12 lymph nodes, no prolonged length of stay, no 30-day readmission/death, and receiving adjuvant chemotherapy. Survival analysis was used to determine the prognostic value of a TOO on overall survival (OS) and recurrence-free survival (RFS). Logistic regression was used to identify the risk factors of a TOO. The rates of a TOO and of each indicator were compared in patients who suffered or not from delayed gastric emptying (DGE). RESULTS A total of 44 (25.73%) patients achieved TOO which was associated with improved median OS (TOO 32 months vs. non-TOO 20 months, P = 0.034) and a better RFS (TOO 19 months vs. non-TOO 13 months, P = 0.053). Patients suffering from DGE [odds ratio (OR) 4.045, 95% CI 1.151-14.214, P = 0.029] were independent risk factors for TOO. In addition, patients with DGE after surgery had a significantly lower rate of TOO (P = 0.015) than patients without DGE. CONCLUSIONS As there were significant differences between patients who achieved TOO or not, TOO is a good indicator for long-term oncologic outcomes in patients with pancreatic head cancer after undergoing LPD. DGE is the risk factor for achieving TOO, so it is important to prevent the DGE after LPD to improve the rate of TOO.

Abstract
INTRODUCTION Postoperative pancreatic fistula (POPF) remains one of the most severe complications of laparoscopic pancreaticoduodenectomy (LPD). Theoretically, transecting the pancreatic neck more distally has both advantages (more blood supply, and more central pancreatic duct) and disadvantages (maybe smaller the pancreatic duct) in preventing POPF. This theoretical contradiction pushed us to organise this trial to explore the impact of the level of pancreatic transection in clinical practice. We conduct this randomised trial with the hypothesis that extended pancreatic neck transection has superiority to conventional pancreatic neck transection. METHODS AND ANALYSIS The LPDEXCEPT (Extended pancreatic neck transection versus conventional pancreatic neck transection during laparoscopic pancreaticoduodenectomy) trial is a multicentre, randomised-controlled, open-label, superiority trial in 4 centres whose annual surgical volume for LPD is more than 25 cases with pancreatic surgeons who had completed their learning curve. A total of 154 patients who meet the inclusive and exclusive criteria are randomly allocated to the extended pancreatic neck transection group or conventional pancreatic neck transection group in a 1:1 ratio. The stratified randomised block design will be applied, with stratified factors are surgical centre and the diameter of the main pancreatic duct measured by preoperative CT scan (preMPD). The primary outcome is the incidence of the clinically relevant pancreatic fistula. ETHICS AND DISSEMINATION Ethics Committee on Biomedical Research of West China Hospital of Sichuan University has approved this trial in March 2023 (approval no. 2023-167). Results of this trial will be published in peer-reviewed journals and conference proceedings. TRIAL REGISTRATION NUMBER NCT05808894.

Abstract
Intra-abdominal adhesions have consistently posed a challenge for surgeons during procedures. This study aims to investigate the feasibility of utilizing indocyanine green (ICG) in conjunction with near-infrared imaging for the detection of intra-abdominal adhesions. In vitro, we analyzed factors affecting ICG fluorescence. We divided SD rats into groups to study ICG excretion in different digestive tract regions. Additionally, we reviewed surgical videos from previous cholecystectomy cases, categorizing them by ICG injection timing and assessing fluorescence imaging in various digestive tract regions. Finally, we preoperatively injected ICG into two cholecystectomized patients with abdominal adhesions, guiding intraoperative adhesiolysis with near-infrared fluorescence imaging. In vitro, we observed a significant influence of protein and ICG concentrations on ICG fluorescence intensity. Our rat experiments unveiled a strong and highly significant correlation (Kendall's tau-b = 1, P < 0.001) between the timing of ICG injection and the farthest point of intestinal fluorescence. A retrospective case analysis further validated this finding (Kendall's tau-b = 0.967, P < 0.001). Under the guidance of fluorescence navigation, two cholecystectomized patients with intra-abdominal adhesions successfully underwent adhesiolysis, and no postoperative complications occurred. The intraoperative combination of ICG with near-infrared fluorescence imaging effectively enhances the visibility of the liver, bile ducts, and various segments of the gastrointestinal tract while providing real-time navigation. This real-time fluorescence guidance has the potential to aid surgeons in the dissection of intra-abdominal adhesions.

Abstract
A novel gas-pressurized (GP) torrefaction method at 250 °C has recently been developed that realizes the deep decomposition of cellulose in lignocellulosic solid wastes (LSW) to as high as 90% through deoxygenation and aromatization reactions. However, the deoxygenation and aromatization mechanisms are currently unclear. In this work, these mechanisms were studied through a developed molecular structure calculation method and the GP torrefaction of pure cellulose. The results demonstrate that GP torrefaction at 250 °C causes 47 wt.% of mass loss and 72 wt.% of O removal for cellulose, while traditional torrefaction at atmospheric pressure has almost no impact on cellulose decomposition. The GP-torrefied cellulose is determined to be composed of an aromatic furans nucleus with branch aliphatic C through conventional characterization. A molecular structure calculation method and its principles were developed for further investigation of molecular-level mechanisms. It was found 2-ring furans aromatic compound intermediate is formed by intra- and inter-molecular dehydroxylation reactions of amorphous cellulose, and the removal of O-containing function groups is mainly through the production of H2O. The three-ring furans aromatic compound intermediate and GP-torrefied cellulose are further formed through the polymerization reaction, which enhances the removal of ketones and aldehydes function groups in intermediate torrefied cellulose and form gaseous CO and O-containing organic molecules. A deoxygenation and aromatization mechanism model was developed based on the above investigation. This work provides theoretical guidance for the optimization of the gas-pressurized torrefaction method and a study method for the determination of molecular-level structure and the mechanism investigation of the thermal conversion processes of LSW.

Abstract
Ras homolog gene family member V (RHOV) is an atypical Rho GTPase that participates in various important cellular processes. Although RHOV has been identified to play an oncogenic role in lung cancer and triple-negative breast cancer, its role in other types of tumors remains unknown. In this study, we investigated the expression of RHOV in pan-cancer analysis using The Cancer Genome Atlas (TCGA) and Gene-Tissue Expression datasets. RHOV mRNA levels were dysregulated in several types of tumors. RHOV expression was identified as an independent prognostic factor in 7 of 33 types of tumors; however, the relationship varied according to tumor type. Higher RHOV expression was associated with a favorable prognosis in kidney renal cell carcinoma and prostate adenocarcinoma, for which RHOV expression was downregulated, whereas RHOV expression was associated with a poor prognosis for patients with adenoid cystic carcinoma, lung adenocarcinoma, pancreatic ductal adenocarcinoma, skin cutaneous melanoma, and uveal melanoma with upregulated RHOV expression. Furthermore, RHOV expression was associated with various clinicopathological parameters in these tumors. RHOV expression showed varied associations with different types of tumor-infiltrating immune cells and demonstrated a potential impact on the response to immunotherapy depending on the cancer type. Additionally, functional enrichment analysis of RHOV-related genes demonstrated a role in a wide range of developmental and immune-related processes. This study provides valuable insights into the role of RHOV in pan-cancer development, indicating its role as a tumor suppressor or oncogene according to the cancer type and tumor microenvironment.

Abstract
Objective The aim of this study was to explore the safety and efficacy of multiple peptide-pulsed autologous dendritic cells (DCs) combined with cytotoxic T lymphocytes (CTLs) in patients with cancer. Methods Five patients diagnosed with cancer between November 2020 and June 2021 were enrolled and received DC-CTLs therapy. Peripheral blood was collected and antigenic peptides were analyzed. The phenotype and function of DC-CTLs and the immune status of patients were detected using flow cytometry or IFN-γ ELISPOT analysis. Results DCs acquired a mature phenotype and expressed high levels of CD80, CD86, CD83, and HLA-DR after co-culture with peptides, and the DC-CTLs also exhibited high levels of IFN-γ. Peripheral blood mononuclear cells from post-treatment patients showed a stronger immune response to peptides than those prior to treatment. Importantly, four of five patients maintained a favorable immune status, of which one patient's disease-free survival lasted up to 28.2 months. No severe treatment-related adverse events were observed. Conclusion Our results show that multiple peptide-pulsed DCs combined with CTLs therapy has manageable safety and promising efficacy for cancer patients, which might provide a precise immunotherapeutic strategy for cancer.

Abstract
OBJECTIVE We investigated the correlation between bone cement distribution and adjacent vertebral fractures (AVFs) after percutaneous vertebroplasty (PVP). METHODS We retrospectively analyzed patients who underwent single-segment PVP for osteoporotic compression fractures in our hospital from January 2016 to January 2021 and divided the patients into 2 groups, A and B, on the basis of the criterion of whether there were AVFs of the operated vertebrae within 1 year after surgery. We compared the general data of the 2 groups, assessed the ability of 3 simple X-ray-based evaluation methods to predict the occurrence of AVF within 1 year after surgery and derived a simple and accurate evaluation method. RESULTS A total of 570 patients were included in this study: 511 patients in group A and 59 patients in group B. There were no statistical differences in the general data such as age, gender, and fracture site between the 2 groups. The posterior-anterior (PA), lateral (LAT), and PA and LAT methods showed receiver operating characteristic curve (ROC) predicted postoperative AVF of 0.611, 0.691, and 0.714, respectively. The difference between the area under curve (AUC) of the PA method and LAT method was statistically significant (P = 0.0307), the difference between the AUC of PA method and PA and LAT method was statistically significant (P < 0.001), and the difference between the AUC of LAT method and PA and LAT method was not statistically significant (P = 0.3308).There was no statistical difference between the 2 groups of patients with PA method point of 1 and statistically different between patients with points of 2 and 3. There was statistical difference in points of 1, 2 and 3 in the LAT method between the 2 groups. There was a positive correlation between cement distribution scores and AVF by linear regression analysis of the 3 evaluation methods. CONCLUSIONS The 3 evaluation methods reliably predict AVF after PVP, with the LAT method, PA and LAT method being more predictive than the PA method, but the LAT method is simpler, with bone cement being widely distributed after crossing the midline in the PA method and contact with the upper and lower end plates in the LAT method being a risk factor for AVF.

Abstract
BACKGROUND Non-standardized insulin injection has an impact on the efficacy of glucose control. OBJECTIVES The aim of the study was to explore the effectiveness of a nursing project in improving the insulin self-injection accuracy of diabetes mellitus patients. MATERIAL AND METHODS A total of 200 type 2 diabetes patients who received insulin therapy with an insulin pen were recruited at the First Affiliated Hospital of Army Medical University (Chongqing, China). Patients were randomly assigned to a control (n = 100) or intervention (n = 100) group. Conventional health education was conducted in the control group, while a nursing project and conventional health education were undertaken in the intervention group. The following parameters were analyzed between the 2 groups: standardized insulin pen use at admission and discharge, glycosylated hemoglobin (HbA1c), time in range (TIR), and adipose hyperplasia incidence rate 6 months after discharge. RESULTS Concerning standardized insulin self-injection, the intervention group was superior to the control group, and the difference between the 2 groups was statistically significant (p < 0.05). The HbA1c levels (p = 0.000), TIR (p = 0.005) and adipose hyperplasia incidence rate 6 months after discharge (p = 0.000) all improved in the intervention group compared to the control group. CONCLUSIONS The application of the nursing project effectively improved the efficacy of glucose control in diabetes mellitus patients.

Abstract
BACKGROUND Recent years have witnessed impressive growth in applying natural medicine in tumor treatment. Saffron is reported to elicit an inhibitory property against BC. Herein, we sought to explore the specific components and mechanistic basis of saffron's anti-breast carcinoma (BC) function. METHODS Bioinformatics analysis was employed to analyze saffron components' anti-BC activity and screen the corresponding target genes involved in BC. Then, the roles of the main saffron ingredient quercetin in the activity of BC cells were examined using CCK-8, MTS, flow cytometry, colony formation, Transwell, and Gelatin zymogram assays. Additionally, the interactions among Quercetin, EET, and Stat3 were assessed by immunofluorescence and Western blot, and LC-MS/MS determined the levels of AA, EETs, and CYP3A. Finally, BC xenograft mouse models were established to verify the anti-BC function of Quercetin in vivo. RESULTS Quercetin, the main active component of saffron, inhibited BC progression. Quercetin suppressed BC cell growth, migration, and invasion and inhibited CYP3A4 expression and activity in BC. Mechanistically, Quercetin down-regulated CYP3A4 to block the nuclear translocation of Stat3 by decreasing the metabolization of AA to EETs, thereby alleviating BC. Moreover, exogenously added EETs counteracted the anti-tumor effect of Quercetin on BC. Quercetin also inhibited the tumor growth of tumor-bearing nude mice. CONCLUSION Quercetin could inhibit the activity of CYP3A to down-regulate AA metabolites EETs, consequently hampering p-Stat3 and nuclear translocation, thus impeding BC development.

Abstract
PURPOSE This study was designed to compare clinical outcomes of the femoral stable interlocking intramedullary nail (FSIIN) with proximal femoral nail anti-rotation (PFNA) for the treatment of intertrochanteric fractures (OTA 31A1 + A2). METHODS This study retrospectively analyzed a registered sample of 74 intertrochanteric fractures (OTA 31A1 + A2) surgically treated using FSIIN (n = 36) or PFNA (n = 38) from January 2015 to December 2021. The intra-operative variables (operation time, fluoroscopy time, intra-operative blood loss, length of incision) and fracture healing time were compared between the two groups in this study. Harris hip score (HHS) and visual analog scale (VAS) were used to evaluate the functional states. At the last follow-up, the incidence of related complications in patients was calculated. Eventually, the 3D finite element model was established to analyze the stress of FSIIN and PFNA. RESULTS The distribution of all basic characteristics was similar between the two groups (p > 0.05). The operation time, fluoroscopy time, intra-operative blood loss, and length of incision were significantly decreased in the FSIIN group (p < 0.001). The FSIIN group had a shorter fracture healing time than the PFNA group (p < 0.001). There is no significant difference between the two groups in the Harris and VAS (p > 0.05). The incidences of post-operative anaemia, electrolyte imbalance, varus malalignment, and thigh pain were significantly lower in FSIIN than in PFNA groups (all p < 0.05). The finite element results show that the stress shielding effect of FSIIN is smaller. CONCLUSIONS Our study revealed that FSIIN seemed to be superior to PFNA in the treatment of intertrochanteric fractures (OTA 31A1 + A2) due to less surgical damage and shorter fracture healing time.

Abstract
BACKGROUND The use of single-incision plus one-port laparoscopic pancreaticoduodenectomy (SILPD + 1) has been never reported, and its safety and efficacy remain unknown. This study aimed to evaluate the short-term outcomes of SILPD + 1 compared with those of conventional laparoscopic pancreaticoduodenectomy (CLPD). METHOD Fifty-seven cases of laparoscopic pancreaticoduodenectomy (LPD) were performed between November 2021, and March 2022. Among them, 10 cases of LPD were performed using a single-incision plus one-port device. Based on the same inclusion and exclusion criteria, 47 cases of LPD performed using traditional 5-trocar were included as a control group. The patient's demographic characteristics, intraoperative, and postoperative variables were prospectively collected and retrospectively analyzed. RESULTS Three men and seven women were included in the SILPD + 1 group. All baseline parameters of both groups were comparable, except for age. Patients were younger in the SILPD + 1 group (47.2 ± 18.3 years vs. 60.6 ± 11.7 years, P = 0.05) than that in the CLPD group. Compared with the CLPD group, median operation time (222.5 (208.8-245.0) vs. 305.0 (256.0-37.0) min, P < 0.001) was shorter, median postoperative VAS scores on days 1-3 were lower, and median cosmetic score (21.0 (19.0-23.5) vs. 17.0 (16.0-20.0), P = 0.026) was higher one month after the surgery in the SILPD + 1 group. The estimated blood loss, conversion rate, blood-transfusion rate, exhaust time, time of drainage tube removal, postoperative hospital stays, and perioperative complications were comparable between the two groups. CONCLUSION In a high-volume LPD center, SILPD + 1 is safe and feasible for well-selected patients without increasing the operation time and complications. It even has the advantages of reduced postoperative pain and improved cosmetic results.

Abstract
BACKGROUND The double-J stent (DJS) is a commonly used ureteral stent in urological surgeries, which provides support and drainage. However, the DJS may result in various complications such as infection, hematuria, stone formation, stent occlusion, and migration. Normally, one end of the DJS is located in the renal pelvis, and the other end in the bladder. In this case report, we describe the rare occurrence of a misplaced DJS during laparoscopic pyeloplasty, which was unintentionally placed in the contralateral renal pelvis. CASE REPORT A 4-month-old male infant was diagnosed with left hydronephrosis. After confirmation of the diagnosis, laparoscopic left pyeloplasty was performed with the placement of a DJS. The patient did not experience any discomfort, such as nausea, vomiting, refusal to feed, crying and restlessness, or fever, after the operation, and was discharged on postoperative day 4. The patient returned to the hospital for DJS removal 6 weeks after the operation. However, the kidneys, ureters, and bladder (KUB) X-ray examination showed that the DJS was unintentionally placed in the contralateral ureter and renal pelvis. The stent was confirmed and removed under cystoscopy. Postoperative examination of the DJS showed that there was a hole in the side of the middle of the stent for urine drainage, with no obstruction or contralateral hydronephrosis. CONCLUSIONS Misplacement of a DJS in the contralateral renal pelvis during laparoscopic pyeloplasty is a rare but potentially serious complication. Surgeons should be cautious when placing the stent and confirm its placement with imaging studies. Patients should be closely monitored for postoperative complications and prompt intervention should be taken if necessary.

Abstract
Background Laparoscopic transduodenal ampullectomy (LTDA) is a function-preserving surgery for pre-malignant tumors of the ampulla of Vater (AoV). However, it is technically challenging, and only a few case reports of LTDA are available in the literature. Methods A total of 43 cases of pre-malignant tumors of AoV were operated in West China Hospital, Sichuan University between January 2017 and July 2022. Among these patients, 9 patients (group 1) underwent LTDA, 19 patients (group 2) underwent laparoscopic pancreaticoduodenectomy (LPD), and 15 patients (group 3) underwent open transduodenal ampullectomy (OTDA). Prospective collection and retrospective analysis of the demographic characteristics, intraoperative variables, and postoperative variables were carried out. Results The patients in the three groups were comparable in terms of sex, age, body mass index, tumor size, and preoperative blood tests. In comparison to the patients in group 2, the patients in group 1 were found to require less operative time (159.7 ± 47.5 min vs. 298.1 ± 62.6, p < 0.01) and suffered lower blood losses (23.3 ± 16.7 ml vs. 156.8 ± 112.1, p = 0.002) and complications. Moreover, the postoperative hospital stays (POHS) were significantly shorter for patients in group 1 (9.0 ± 5.3 days vs. 15.5 ± 7.3 days, p = 0.04). Compared to patients who underwent OTDA, the patients in LTDA suffered from less blood loss. The operative time and post-operative details were comparable. Conclusion Therefore, LTDA was found to be safe and feasible in the setting of pre-malignant tumors of AoV in well-selected patients. However, multidisciplinary preoperative planning is essential before the surgery.

Abstract
BACKGROUND Pathophysiologic platelet activation leads to thrombo-occlusive diseases such as myocardial infarction or ischemic stroke. Niemann-Pick C1 protein (NPC1) is involved in the regulation of lysosomal lipid trafficking and calcium ion (Ca2+) signaling, and its genetic mutation causes a lysosomal storage disorder. Lipids and Ca2+ are key players in the complex orchestration of platelet activation. OBJECTIVES The present study aimed to determine the impact of NPC1 on Ca2+ mobilization during platelet activation in thrombo-occlusive diseases. METHODS Using MK/platelet-specific knockout mice of Npc1 (Npc1Pf4∆/Pf4∆), ex vivo and in vitro approaches as well as in vivo models of thrombosis, we investigated the effect of Npc1 on platelet function and thrombus formation. RESULTS We showed that Npc1Pf4∆/Pf4∆ platelets display increased sphingosine levels and a locally impaired membrane-associated and SERCA3-dependent Ca2+ mobilisation compared to platelets from wildtype littermates (Npc1lox/lox). Further, we observed decreased platelet. CONCLUSION Our findings highlight that NPC1 regulates membrane-associated and SERCA3-dependent Ca2+ mobilization during platelet activation and that MK/platelet-specific ablation of Npc1 protects against experimental models of arterial thrombosis and myocardial or cerebral ischemia/reperfusion injury.

Abstract
Despite advances in transdermal drug delivery for treating psoriasis, there are still unmet medical needs, hyaluronic acid (HA)-based topical formulations as nanocarriers, which can increase drug concentration in psoriatic skin through CD44-assisted targeting. Here, HA was utilized as a matrix for nanocrystal-based hydrogel (NC-gel) to deliver indirubin topically for psoriasis treatments. Indirubin nanocrystals (NCs) were prepared through wet media milling and were then mixed with HA to create indirubin NC/HA gels. A mouse model of imiquimod (IMQ)-induced psoriasis and M5-induced keratinocyte proliferation were established. Then, the efficacy of indirubin delivery targeted at CD44, and anti-psoriatic efficacy using indirubin NC/HA gels (HA-NC-IR group) were evaluated. The HA hydrogel network embedding indirubin NCs enhanced cutaneous absorption of poorly water-soluble indirubin. The co-localization of CD44 and HA in psoriasis-like inflamed skin was highly elevated, suggesting that indirubin NC/HA gels specifically adhered to CD44, leading to an increase in indirubin accumulation in the skin. Additionally, indirubin NC/HA gels enhanced the anti-psoriatic effect of indirubin in both a mouse model and HaCaT cells stimulated with M5. The results indicate that NC/HA gels targeting overexpressed CD44 protein can improve the delivery of topical indirubin to psoriatic inflamed tissues. This suggests that a topical drug delivery system could be a viable approach for formulating multiple insoluble natural products to treat psoriasis.

Abstract
INTRODUCTION The placental tissue stress of intrahepatic cholestasis of pregnancy (ICP) is activated by ERS under hypoxia condition. PERK signaling pathway is the key pathway for UPR regulation, and is first to activated during ERS. WFS1, as an important regulatory gene of UPR pathway, participates in ERS regulation. The purpose of our study is to explore the expression level and mutual regulation mechanisms of WFS1 and PERK-mediated UPR pathway in ICP placental tissue cell under stress. METHODS Blood and placenta samples were obtained from the ICP patients and ethinylestradiol (EE)-induced intrahepatic cholestasis pregnant rats. IHC and WB were used to detect the expression of WFS1, key factors of PERK pathway (GRP78, PERK, eIF2a, P-eIF2α, ATF4) and placental stress peptides (CRH, UCN). Furthermore, qPCR was carried out to detect mRNA expression of above indicators. RESULTS The expression levels of WFS1 and key factors of PERK pathway were significantly increased in severe ICP placental tissues. Moreover, qPCR and WB showed that relative mRNA and protein expression levels of WFS1 and key factors of PERK pathways in placenta tissues of severe ICP and EE-induced intrahepatic cholestasis pregnant rats were higher than those in control group to varying degrees, while CRH and UCN were descended. Meanwhile, after WFS1-siRNA targeted silencing of the WFS1 gene, the protein expression levels of PERK, P-eIF2α, ATF4 were significantly increased, while CRH and UCN protein were significantly decreased. DISCUSSION Our study revealed that the activation of WFS1 and PERK-p-eIF2α-ATF4 signaling pathway may contribute to stress regulation in placental tissue cells of intrahepatic cholestasis of pregnancy, thereby avoiding adverse pregnancy outcomes.

Abstract
BACKGROUND Solid pseudopapillary tumor (SPT) of the pancreas is a rare low-grade malignant tumor. Here, we aimed to determine the safety and feasibility of laparoscopic parenchyma-sparing pancreatectomy for SPT located in the pancreatic head. METHODS From July 2014 to February 2022, 62 patients with SPT located in the pancreatic head were operated laparoscopically in two institutions. These patients were divided into two groups according to the operative strategy: laparoscopic parenchyma-sparing pancreatectomy (27 patients, group 1) and laparoscopic pancreaticoduodenectomy (35 patients, group 2). The clinical data were retrospectively collected and analyzed in terms of demographic characteristics, perioperative variables, and long-term follow-up outcomes. RESULTS The demographic characteristics of the patients in the two groups were comparable. Compared to the patients in group 2, those in group 1 required less operative time (263.4 ± 37.2 min vs. 332.7 ± 55.6 min, p < 0.001) and experienced less blood loss (105.1 ± 36.5mL vs. 188.3 ± 150.7 mL, p < 0.001). None of the patients in group 1 had tumor recurrence or metastasis. However, 1 (2.5%) patient in group 2 showed liver metastasis. CONCLUSION Laparoscopic parenchyma-sparing pancreatectomy is a safe and feasible approach for SPT located in the pancreatic head, with favorable long-term functional and oncological results.

Abstract
Alkali and alkaline earth metals (AAEMs) in agricultural organic solid waste (AOSW) contribute to the fouling and slagging during its combustion. In this study, a novel flue gas-enhanced water leaching (FG-WL) method using flue gas as the heat and CO2 source was proposed for effective AAEM removal from AOSW before combustion. The removal rate of AAEMs by FG-WL was significantly superior to that by conventional water leaching (WL) under the same pretreatment conditions. Furthermore, FG-WL also obviously reduced the release of AAEMs, S, and Cl during AOSW combustion. The ash fusion temperatures of the FG-WL-treated AOSW was higher than that of WL. The fouling and slagging tendency of AOSW greatly decreased through FG-WL treatment. Thus, FG-WL is a simple and feasible method for AAEM removal from AOSW and suppressing fouling and slagging during its combustion. Besides, it also provides a new pathway for the resource utilization of power plant flue gas.

Abstract
BACKGROUND The rate of bile duct injury in laparoscopic cholecystectomy (LC) continues to be high due to low critical view of safety (CVS) achievement and the absence of an effective quality control system. The development of an intelligent system enables the automatic quality control of LC surgery and, eventually, the mitigation of bile duct injury. This study aims to develop an intelligent surgical quality control system for LC and using the system to evaluate LC videos and investigate factors associated with CVS achievement. MATERIALS AND METHODS SurgSmart, an intelligent system capable of recognizing surgical phases, disease severity, critical division action, and CVS automatically, was developed using training datasets. SurgSmart was also applied in another multicenter dataset to validate its application and investigate factors associated with CVS achievement. RESULTS SurgSmart performed well in all models, with the critical division action model achieving the highest overall accuracy (98.49%), followed by the disease severity model (95.45%) and surgical phases model (88.61%). CVSI, CVSII, and CVSIII had an accuracy of 80.64, 97.62, and 78.87%, respectively. CVS was achieved in 4.33% in the system application dataset. In addition, the analysis indicated that surgeons at a higher hospital level had a higher CVS achievement rate. However, there was still considerable variation in CVS achievement among surgeons in the same hospital. CONCLUSIONS SurgSmart, the surgical quality control system, performed admirably in our study. In addition, the system's initial application demonstrated its broad potential for use in surgical quality control.

Abstract
OBJECTIVE The purpose of this study was to evaluate the clinical efficacy of laparoscopic pyeloureteroplasty in the treatment of children suffering from hydronephrosis. PATIENTS AND METHODS Our pediatric department received 160 children with hydronephrosis from January 2019 through December 2021. These children were randomly assigned to either the control group or the study group with 80 cases in each group. The control group underwent traditional open pyeloureteroplasty, while the study group underwent laparoscopic pyeloureteroplasty. After assessing the results of both groups, the clinical outcomes were compared. RESULTS The study group had a significantly shorter operating time, lower intraoperative bleeding rate, and shorter hospital stay than the control group. On the first day after the operation, there was no significant difference between the control and study groups, and on the seventh day after the operation, the study group's OPS was significantly lower than that of the control group. A significant difference was observed after treatment between the study group and the control group in terms of the anteroposterior diameter of the renal pelvis. Both groups' GFR increased significantly with time, and the GFR of the study group was significantly greater than that of the control group at 3 months after the operation, but there was no significant difference at 6 months after the operation. Postoperative adverse effects did not differ significantly between the two groups. CONCLUSIONS Pediatric laparoscopic pyeloureteroplasty can reduce intraoperative bleeding, shorten operation time and hospital stay, alleviate postoperative pain, and promote the recovery of postoperative renal morphology and function in children with hydronephrosis, which merits further discussion.

Abstract
Microsomal Prostaglandin E Synthase 1 (mPGES-1) is the key enzyme for the generation of the pro-inflammatory lipid mediator prostaglandin E2 (PGE2), which contributes to several pathological features of many diseases. Inhibition of mPGES-1 has been shown to be a safe and effective therapeutic strategy in various pre-clinical studies. In addition to reduced PGE2 formation, it is also suggested that the potential shunting into other protective and pro-resolving prostanoids may play an important role in resolution of inflammation. In the present study, we analysed the eicosanoid profiles in four in vitro inflammation models and compared the effects of mPGES-1 inhibition with those of cyclooxygenase-2 (Cox-2) inhibition. Our results showed a marked shift to the PGD2 pathway under mPGES-1 inhibition in A549 cells, RAW264.7 cells and mouse bone marrow-derived macrophages (BMDMs), whereas enhanced prostacyclin production was observed in rheumatoid arthritis synovial fibroblasts (RASFs) treated with an mPGES-1 inhibitor. As expected, Cox-2 inhibition completely suppressed all prostanoids. This study suggests that the therapeutic effects of mPGES-1 inhibition may be mediated by modulation of other prostanoids in addition to PGE2 reduction.

Abstract
OBJECTIVE This study was performed to evaluate the clinical efficacy of the modified Brisson+Devine procedure in the management of concealed penis. PATIENTS AND METHODS In this retrospective study, the medical data of 45 children diagnosed with concealed penis who underwent modified Brisson+Devine procedure in the Department of Urology of Anhui Provincial Children's Hospital between January 2019 and December 2021 were analyzed. Follow-up visits were performed at one, three, and six months postoperatively, and outcome measures included postoperative complications and parental satisfaction. RESULTS All 45 children completed the surgery uneventfully. At 3-4 days after surgery, the penile dressing and the urinary catheter were removed. The patients were discharged 4-5 days postoperatively without ischemic necrosis of metastatic flaps. The follow-up visits spanned from 7 to 33 months, with a mean of 14.6 months. A statistically significant increase in the penile length after surgery was observed (p<0.05). The postoperative penile appearance was good, and the parents of the children had high treatment satisfaction (p<0.05). 38 children developed postoperative transferred flap edema, and the edema disappeared at 3 months postoperatively. CONCLUSIONS The modified Brisson+ Devine procedure for concealed penis allows maximum use of the foreskin to improve the appearance of the penis and has a high safety profile by reducing postoperative complications, and provides high treatment satisfaction.

Abstract
As one of the most common clinical disorders, low back pain (LBP) influences patient quality of life and causes substantial social and economic burdens. Many factors can result in LBP, the most common of which is intervertebral disc degeneration (IDD). The progression of IDD cannot be alleviated by conservative or surgical treatments, and gene therapy, growth factor therapy, and cell therapy have their own limitations. Recently, research on the use of hydrogel biomaterials for the treatment of IDD has garnered great interest, and satisfactory treatment results have been achieved. This article describes the classification of hydrogels, the methods of decellularized extracellular matrix (dECM) production and the various types of gel formation. The current research on dECM hydrogels for the treatment of IDD is described in detail in this article. First, an overview of the material sources, decellularization methods, and gel formation methods is given. The focus is on research performed over the last three years, which mainly consists of bovine and porcine NP tissues, while for decellularization methods, combinations of several approaches are primarily used. dECM hydrogels have significantly improved mechanical properties after the polymers are cross-linked. The main effects of these gels include induction of stem cell differentiation to intervertebral disc (IVD) cells, good mechanical properties to restore IVD height after polymer cross-linking, and slow release of exosomes. Finally, the challenges and problems still faced by dECM hydrogels for the treatment of IDD are summarised, and potential solutions are proposed. This paper is the first to summarise the research on dECM hydrogels for the treatment of IDD and aims to provide a theoretical reference for subsequent studies.

Abstract
BACKGROUND Discogenic low back pain (DLBP) has been influencing people's quality of life. Research on platelet-rich plasma (PRP) for DLBP has increased in recent years, but systematic summaries are lacking. This study analyzes all published studies related to the use of intradiscal injection of PRP for the treatment of DLBP and summarizes evidence-based medicine for the efficacy of this biologic treatment for DLBP. METHODS Articles published from the inception of the database to April 2022 were retrieved from PubMed, the Cochrane Library, Embase, ClinicalTrial, the Chinese National Knowledge Infrastructure, Wanfang, Chongqing VIP Chinese Scientific Journals, and the Chinese Biomedicine databases. After the rigorous screening of all studies on PRP for DLBP, a meta-analysis was performed. RESULTS Six studies, including 3 randomized controlled trials and 3 prospective single-arm trials, were included. According to this meta-analysis, pain scores decreased by >30% and >50% from baseline, with incidence rates of 57.3%, 50.7%, and 65.6%, and 51.0%, 53.1%, and 51.9%, respectively, after 1, 2, and 6 months of treatment. The Oswestry Disability Index scores decreased by >30% with an incidence rate of 40.2% and by >50% with an incidence rate of 53.9% from baseline after 2 and 6 months, respectively. Pain scores decreased significantly after 1, 2, and 6 months of treatment (standardized mean difference: 1 month, -1.04, P = .02; 2 months, -1.33, P = .003; and 6 months, -1.42, P = .0008). There was no significant change (P > .05) in the pain scores and the incidence rate when pain scores decreased by >30% and >50% from baseline between 1 and 2 months, 1 and 6 months, and 2 and 6 months after treatment. No significant adverse reactions occurred in any of the 6 included studies. CONCLUSION Intradiscal injection of PRP is effective and safe in the treatment of DLBP, and there was no significant change in the patient's pain 1, 2, and 6 months after PRP treatment. However, confirmation is required by additional high-quality studies due to the limitations of the quantity and quality of the included studies.

Abstract
BACKGROUND The results of laparoscopic pancreaticoduodenectomy combining with mesentericoportal vein resection and reconstruction (LPD-MPVRs) for pancreatic head adenocarcinoma are rarely reported. The aim of present study was to explore the short- and long-term outcomes of different type of LPD-MPVRs. METHODS Patients who underwent LPD-MPVRs in 14 Chinese high-volume pancreatic centers between June 2014 and December 2020 were selected and compared. RESULTS In total, 142 patients were included and were divided into primary closure (n = 56), end-end anastomosis (n = 43), or interposition graft (n = 43). Median overall survival (OS) and median progress-free survival (PFS) between primary closure and end-end anastomosis had no difference (both P > 0.05). As compared to primary closure and end-end anastomosis, interposition graft had the worst median OS (12 months versus 19 months versus 17 months, P = 0.001) and the worst median PFS (6 months versus 15 months versus 12 months, P < 0.000). As compared to primary closure, interposition graft had almost double risk in major morbidity (16.3 percent versus 8.9 percent) and about triple risk (10 percent versus 3.6 percent) in 90-day mortality, while End-end anastomosis had only one fourth major morbidity (2.3 percent versus 8.9 percent). Multivariate analysis revealed postoperation hospital stay, American Society of Anesthesiologists (ASA) score, number of positive lymph nodes had negative impact on OS, while R0, R1 surgical margin had protective effect on OS. Postoperative hospital stay had negative impact on PFS, while primary closure, end-end anastomosis, short-term vascular patency, and short-term vascular stenosis positively related to PFS. CONCLUSIONS In LPD-MPVRs, interposition graft had the worst OS, the worst PFS, the highest rate of major morbidity, and the highest rate of 90-day mortality. While there were no differences in OS and PFS between primary closure and end-end anastomosis.

Abstract
PURPOSE Pancreaticojejunostomy stricture (PJS) is an uncommon late complication of laparoscopic pancreaticoduodenectomy (LPD). The incidence, clinical characteristics, and managements of PJS after LPD are still unreported. METHODS All patients undergoing LPD between January 2015 and December 2019 were identified from an institutional database. All pancreaticojejunostomies were performed using Bing's duct-to-mucosa anastomosis. PJS was diagnosed by computed tomography or magnetic resonance cholangio-pancreatography with secretin administration. Re-operation was performed in those patients with persistent abdominal pain and/or recurrent pancreatitis. Patients' demographic characteristics, perioperative outcomes, and follow-up outcomes were retrospectively collected. RESULTS During the 5-year study period, 506 cases of LPD were performed. Among these patients, 13 patients (2.6%) were diagnosed with PJS. Only seven patients presented with abdominal pain and/or recurrent pancreatitis and underwent re-operation. The interval between the diagnosis of PJS and the original operation was 23 months. The median operative time was 140 min (range 90 to 210 min). The estimated blood loss was 40 ml (range 10 to 100 ml). The post-operative outcomes were favorable. Only one patient suffered from biochemical fistula. Six of these 7 patients (85.7%) reported complete pain resolution after the re-operation. The other patient reported partial resolution after surgery. All patients did not need to take analgesic drugs after the operation. CONCLUSION PJS following LPD is a late complication that was underestimated. It is technically safe and clinically effective to perform laparoscopic revision of the PJS after LPD.

Abstract
BACKGROUND The procedure of choice for the resection of ampullary tumors comprises transduodenal ampullectomy (TDA), endoscopic papillectomy (EP), and pancreaticoduodenectomy (PD).1 For neoplasms with low-grade dysplasia, TDA and EP have equivalent efficacies and lower morbidities than PD1. Compared with EP, also as an organ-preserving procedure, TDA could be applicable for tumors involving the pancreatic ducts or common bile ducts.2 Because TDA has a lower incidence of postoperative gastrointestinal bleeding and a higher R0 resection rate, its use could avoid the need to use multiple endoscopic procedures for larger lesions.3 Furthermore, during TDA, surgeons could convert to PD as necessary. However, TDA has rarely been performed using a minimally invasive approach that addresses the shortcomings of both the endoscopic and open surgical techniques without adding significant morbidity or compromising outcomes.2,4 Conventional laparoscopic TDA (LTDA) remains limited due to the complexity of the surgical anatomy of the ampulla and the reconstruction required compared with robot-assisted procedures.2-5 However, robot-assisted surgery is less popular and much more expensive than laparoscopic surgery. This report with a video describes the LTDA approach to standardize and simplify the surgical processes. METHODS A 48-year-old man was admitted to the hospital with epigastric pain. He had a history of cholecystolithiasis with chronic cholecystitis. A tumor approximately 2.2 cm in diameter located in the duodenal papilla was diagnosed by an enhanced computed tomography (CT) scan. The endoscopic biopsy result indicated a villous adenoma with moderate dysplasia. Laparoscopic TDA and cholecystectomy were planned. However, if the frozen sample analysis showed adenocarcinoma, laparoscopic PD (LPD) would be applied. The patient was placed in the supine position with both legs apart. Trocars were distributed in the same manner as in the authors' previous study to facilitate conversion to LPD.6 The procedure began with kocherization and dissection of the gastrocolic ligament to explore the second and third portions of the duodenum. A figure-eight suture was made using 4-0 prolene in the seromuscular layer, and then the duodenum was retracted to the left side of the patient. A longitudinal duodenotomy was made, and the ampulla of Vater was identified. A transfixing suture was placed through the tumor. Submucosal injection of norepinephrine (1:500) was performed to divide the mucosa from the muscular planes. Ampullectomy was performed by first dissecting in the submucosal plane with a harmonic scalpel at the 6 o'clock position until the pancreatic duct was reached. A 6-Fr plastic catheter was inserted into the pancreatic duct for subsequent reconstruction. Continued dissection around the tumor identified the bile duct. Another 6-Fr plastic catheter was inserted into the bile duct. The dissection was completed in the submucosal plane, and the specimen was retrieved for frozen sectioning. After confirmation of villous adenoma with moderate dysplasia and the proximal margin without residual tumor on frozen biopsy, reconstruction was performed. The septum between the ducts was plastered, and the bile and pancreatic ducts were reconstructed on the duodenal wall with 5-0 PDS-II interrupted sutures to ensure that these ducts remained patent and connected. After reconstruction, the plastic catheter was kept in the pancreatic duct but removed from the bile duct. Then, cholecystectomy was applied. Finally, the duodenum was closed obliquely in two layers, and two drains were routinely placed. RESULTS The operation time was 139 min, and the estimated blood loss was 50 ml. Final pathology confirmed villous adenoma with mild to moderate dysplasia. The postoperative course was uneventful, with a hospital stay of 9 days. There was no evidence of recurrence or patency of the reimplanted ducts 5 months after surgery. From February 2022 to May 2022, four cases of LTDA with the same surgical processes were managed by the authors, and all the patients recovered quickly without any postoperative complications. CONCLUSION After standardization of the surgical processes, laparoscopic TDA was safe for highly selected patients. However, long-term follow-up is required to observe the quality of life and survival of patients.

Abstract
BACKGROUND Performing a single-port laparoscopic pancreatectomy is technically challenging. Single-port laparoscopic pancreaticoduodenectomy (SPLPD) is rarely reported in English literature. METHODS Eighty-seven cases of laparoscopic pancreaticoduodenectomy (LPD) were performed by a single surgical team in the Department of Pancreatic Surgery, West China Hospital, Sichuan University between February 2020 and December 2020. Among these, 13 cases of LPD (group 1) were performed using a single-port device. Basing on the same inclusion and exclusion criteria, 68 cases of LPD performed using traditional 5-trocar were included as a control group (group 2). The patient's demographic characteristics, intraoperative, and postoperative variables were prospectively collected and retrospectively analyzed. RESULTS Five men and eight women were included in the SPLPD group. The median age of these patients was 57 years. The patients who underwent SPLPD required a longer operative time (332.7 ± 38.1 min vs. 305.8 ± 64.7 min; p = 0.03) than those in the LPD group. The estimated blood loss, conversion rate, blood transfusion rate, time to oral intake, postoperative hospital stays, and perioperative complications were comparable between the two groups. The short-term oncological outcomes, such as R0 rate and lymph node harvested, were comparable between the two groups. The 90-day mortality of all patients was zero. CONCLUSIONS SPLPD is a safe and feasible procedure for well-selected patients in an experienced minimally invasive pancreatic surgery team. SPLPD may provide several potential advantages, such as the requirement of fewer trocars, fewer abdominal complications, and reduced participation of assistants than conventional LPD.

Abstract
PURPOSE To investigate the association between sarcopenia and overactive bladder (OAB) in a United States adult population from 2011 to 2018, and whether sarcopenia can predict the risk of OAB. MATERIALS AND METHODS We analyzed data from the 2011-2018 National Health and Nutrition Examination Survey in a cross-sectional study(NHANES) of 8746 participants, of whom 1213 were diagnosed with OAB, we analyzed correlations by sex, age, race, education level, marital status, household income-to-poverty ratio, hypertension, diabetes, strenuous work activity, moderate work activity, strenuous recreational activity, moderate recreational activity, blood urea nitrogen, creatinine, and uric acid levels using restricted cubic spline plots of dose-response curves, univariate and multivariate Logistic regression. Models based on sex, age, education, household income to poverty ratio, hypertension, diabetes, sarcopenia index, and cotinine were developed and evaluated using Nomogram, calibration curves, receiver operating characteristic curves, and clinical decision curves. RESULTS Of the 1213 OAB patients, 388 (32.0%) were male and 825 (68.0%) were female. Univariate and multivariate Logistic regression analysis showed that sarcopenia index was negatively correlated with the prevalence of OAB (OR=0.084, 95% CI, 0.056 - 0.130, P <0.001;OR=0.456, 95%CI, 0.215-0.968, P= 0.0041). Dose curve analysis of the sarcopenia index and prevalence of OAB showed that the prevalence of OAB decreased significantly with increasing sarcopenia index. Sarcopenia was positively correlated with OAB (OR=2.400, 95%CI, 2.000 - 2.800, P <0.001;OR=1.46, 95%CI, 1.096 -1.953, P = 0.010). In addition, our model shows that sarcopenia can predict the prevalence of OAB (AUC = 0.750) and has some clinical decision-making implications. CONCLUSION Sarcopenia is positively associated with the risk of OAB in United States adults and can be used as a predictor of OAB prevalence.

Abstract
OBJECTIVES We aim to investigate the regulatory mechanisms of miR-455-5p/SOCS3 pathway that underlie the proliferation, migration, and invasion of triple-negative breast cancer (TNBC) cells. METHODS Reverse transcription-quantitative PCR (RT-qPCR) was used to detect miR-455-5p expression in breast cancer tissues and cell lines. CCK8 and Transwell assays were conducted to assess the effects of miR-455-5p on breast cancer line proliferation, migration, and invasion. SOCS3 expression level in breast cancer tissues and cell lines was determined by qPCR and western blotting. The targeting relationship between miR-455-5p and SOCS3 was determined by dual luciferase reporter gene assay in different breast cancer cell lines. Finally, the upstream and downstream regulatory association between miR-455-5p and SOCS3 was confirmed in breast cancer cells by CCK8, western blot, and Transwell assays. RESULTS MiR-455-5p expression was up-regulated in breast cancer tissues; miR-455-5p regulates TNBC proliferation, migration, and invasion of TNBC. SOCS3 was the direct target of miR-455-5p and was down-regulated in breast cancer. Interference with SOCS3 reversed the inhibitory effect of the miR-455-5p inhibitor on breast cancer cells' malignant potential. CONCLUSION MiR-455-5p promotes breast cancer progression by targeting the SOCS3 pathway and may be a potential therapeutic target for breast cancer.

Abstract
Proteins subjected to post-translational modifications, such as citrullination, carbamylation, acetylation or malondialdehyde (MDA)-modification are targeted by autoantibodies in seropositive rheumatoid arthritis (RA). Epidemiological and experimental studies have both suggested the pathogenicity of such humoral autoimmunity, however, molecular mechanisms triggered by anti-modified protein antibodies have remained to be identified. Here we describe in detail the pathways induced by anti-MDA modified protein antibodies that were obtained from synovial B cells of RA patients and that possessed robust osteoclast stimulatory potential and induced bone erosion in vivo. Anti-MDA antibodies boosted glycolysis in developing osteoclasts via an FcγRI, HIF-1α and MYC-dependent mechanism and subsequently increased oxidative phosphorylation. Osteoclast development required robust phosphoglyceride and triacylglyceride biosynthesis, which was also enhanced by anti-MDA by modulating citrate production and expression of the glycerol-3-phosphate dehydrogenase 1 (GPD1) and glycerol-3-phosphate acyltransferase 2 (GPAT2) genes. In summary, we described novel metabolic pathways instrumental for osteoclast differentiation, which were targeted by anti-MDA antibodies, accelerating bone erosion, a central component of RA pathogenesis.

Abstract
OBJECTIVE To compare the effectiveness of a six-month home-based telerehabilitation based on the Internet-based rehabilitation management system coupled with conventional outpatient care in elderly patients with hip fractures following total hip replacement (THR). METHODS Elderly patients (aged over 65 years) with first hip fractures who underwent THR between March 2018 and September 2018 in Tianjin Hospital were enrolled in this study. Patients were divided into two groups: telerehabilitation group (n = 43) and telephone group (n = 42). A Internet-based telerehabilitation management system was established and applied on patients in the telerehabilitation group. For patients in the telephone group, the rehabilitation intervention was administered through conventional outpatient care (telephone along with outpatient follow-up). Data from the Harris hip scale (HHS), functional independence measure (FIM), self-rating anxiety scale (SAS), and postoperative complications at 1, 3, and 6 months after surgery were collected and compared between the two groups. RESULTS A total of 85 elderly patients completed the 6-month follow-up assessment. Results showed that the HHS score was significantly higher in the telerehabilitation group than in the telephone group at 1 month (66.35 ± 4.63 vs 63.48 ± 4.49), 3 months (76.33 ± 4.52 vs 71.81 ± 3.84), and 6 months (84.23 ± 3.13 vs 77.29 ± 4.95) after surgery (P < 0.001). The FIM score was significantly higher in the telerehabilitation group than in the telephone group at 1 month (89.00 ± 5.63 vs 73.35 ± 8.70), 3 months (100.16 ± 4.56 vs 92.81 ± 5.17), and 6 months (111.70 ± 3.13 vs 98.64 ± 5.12) after surgery (P < 0.001). The SAS score was significantly lower in the telerehabilitation group than in the telephone group at 1 month (42.40 ± 3.07 vs 46.21 ± 3.53), 3 months (36.77 ± 2.26 vs 40.24 ± 1.66), and 6 months (29.26 ± 1.63 vs 33.81 ± 2.62) after surgery (P < 0.001). The overall complication rate was significantly lower in the telerehabilitation group than in the telephone group (14% vs 40.5%) (P < 0.05). CONCLUSION Internet-based rehabilitation management system can not only promote the physical rehabilitation of patients, but also play a positive role in psychological rehabilitation and the prevention of complications, which provides new ideas and methods for clinical rehabilitation.

Abstract
Abstract
Background
The preservation of biological and physiological vitality as well as the formation of dentin are among the main tasks of human dental pulp for a life time. Odontoblastic differentiation of human dental pulp stem cells (hDPSCs) exhibits the capacity of dental pulp regeneration and dentin complex rebuilding. Exploration of the mechanisms regulating differentiation and proliferation of hDPSCs may help to investigate potential clinical applications. BTB and CNC homology 1 (BACH1) is a transcription repressor engaged in the regulation of multiple cellular functions. This study aimed to investigate the effects of BACH1 on the proliferation and odontoblastic differentiation of hDPSCs in vitro.
Methods
hDPSCs and pulpal tissues were obtained from extracted human premolars or third molars. The distribution of BACH1 was detected by immunohistochemistry. The mRNA and protein expression of BACH1 were examined by qRT-PCR and Western blot analysis. BACH1 expression was regulated by stable lentivirus-mediated transfection. Cell proliferation and cell cycle were assessed by cell counting kit-8 assay, 5-Ethynyl-2'-deoxyuridine assay and flow cytometry. The expression of mineralization markers, alkaline phosphatase (ALP) activity and alizarin red S staining were conducted to assess the odontoblastic differentiation ability.
Results
BACH1 expression was stronger in the odontoblast layer than in the cell rich zone. The total and nuclear protein level of BACH1 during odontoblastic differentiation was downregulated initially and then upregulated gradually. Knockdown of BACH1 greatly inhibited cell proliferation, arrested cell cycle, upregulated the heme oxygenase-1 (HO-1) expression and attenuated ALP activity, decreased calcium deposits and downregulated the expression of mineralization markers. Treatment of Tin-protoporphyrin IX, an HO-1 inhibitor, failed to rescue the impaired odonto/osteogenic differentiation capacity. Overexpression of BACH1 increased cell proliferation, ALP activity and the expression of mineralization markers.
Conclusions
Our findings suggest that BACH1 is an important regulator of the proliferation and odontoblastic differentiation of hDPSCs in vitro. Manipulation of BACH1 expression may provide an opportunity to promote the regenerative capacity of hDPSCs.

Abstract
Objective To compare the effect of ultrasound (US)-guided dry needling (DN) with traditional DN in the treatment of pain and dysfunction for patients with knee osteoarthritis (KOA). Design A double-blind, randomized controlled trial. Methods Patients (25 male and 65 female), age 50–80 years diagnosed with KOA were recruited and randomly assigned to one of three groups in a 1:1:1 ratio for intervention: real US-guided DN with exercise therapy (G1), placebo US-guided DN with exercise therapy (G2), and exercise therapy solely (G3). G1 and G2 were blinded to the application of real or placebo US guidance by turning the monitor of US imaging out-of-view from participants’ vantage points. The effectiveness of blinding was evaluated by asking the participants whether they had received real-US guided DN. The responses were assessed by Chi-square test. Visual Analogue Scale (VAS), Knee injury, and Osteoarthritis Outcome Score (KOOS) subscales (KOOS-pain, KOOS-symptoms, KOOS-quality-of-life (QoL)) were collected at baseline, 4 weeks, and 8 weeks by a blinded assessor. Data were analyzed by mixed model analysis of variance (ANOVA) with Bonferroni correction. Results Eighty-four participants (61.26±5.57 years) completed the study. G1 achieved significant improvement in VAS at 8 weeks compared to G2 and G3 (G1 vs. G2: MD = -15.61, 95% CI [-25.49, -5.51], p = 0.001; G1 vs. G3: MD = -19.90, 95% CI [-29.71, -10.08], p< 0.001). G1 achieved significant improvement in KOOS-pain at 8 weeks compared to G2 and G3 (G1 vs. G2: MD = 9.76, 95% CI [2.38, 17.14], p = 0.006; G1 vs. G3: MD = 9.48, 95% CI [2.31, 16.66], p = 0.010). KOOS-symptoms and KOOS-QoL were not statistically significant between groups. G2 had no significant difference of the perceptions as G1 with p = 0.128. G2 were successfully blinded to placebo US-guided DN. Conclusion US-guided DN with exercise therapy may be more effective than traditional DN with exercise therapy or exercise therapy alone in reduce pain of KOA.

Abstract
Background Radical antegrade modular pancreatosplenectomy (RAMPS) has been proven to improve R0 resection and lymph harvest in treating patients with distal pancreatic cancer. The development of minimally invasive surgery has advantages in postoperative recovery. Therefore, minimally invasive (MI-) RAMPS may combine the advantages of both benefits to improve survival. Nevertheless, evidence to validate the safety and efficacy of MI-RAMPS is limited. Method/Design The MIRROR trial will be the first multicenter prospective randomized clinical trial to investigate the outcome of MI-RAMPS. The hypothesis is that MI-RAMPS is superior in postoperative recovery. The primary outcome is the length of postoperative stay. Based on the hypothesis and primary outcome, the sample size is 250 patients (125 participants in each group). The trial will investigate factors related to surgical safety, short-term outcome, pathological assessment, and survival as secondary outcomes. Conclusion This study will offer a relatively higher level of evidence to further illustrate the accessibility and benefits of MI-RAMPS for the treatment of distal pancreatic cancer. Clinical Trial Registration Clinicaltrials.gov, NCT03770559.

Abstract
BACKGROUND Laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS) has not been widely performed due to its technical challenging. We introduce a novel approach, named "Plane first" approach, for L-RAMPS in this study. METHODS From January 2015 to August 2021, we performed 51 cases of L-RAMPS. Patients were divided into two groups basing on the surgical approach: conventional approach (group 1) and "Plane first" approach (group 2). Data were retrospectively collected in terms of demographic characteristics, intra-operative variables, post-operative variables, and follow-up outcomes. RESULTS The age, sex, BMI, and tumor size were comparable between two groups. Two patients in the group 1 required converting to open surgery. The patients in the group 2 required fewer operative time (210.5 ± 65.5 min vs. 252.4 ± 24.7 min, p < 0.01). They also suffered from less blood loss (136.0 ± 100.0 ml vs. 158.8 ± 137.0 ml, p = 0.15). The overall complications for patients in two groups were comparable. In terms of oncological outcomes, posterior margin was positive in two patients (10.5%) in the group 1. One patient (3.1%) in the group 2 had positive pancreatic neck margin. The number of lymph nodes harvested and overall survival between the two groups were comparable. CONCLUSION "Plane first" approach RAMPS for patients with pancreatic adenocarcinoma in the left pancreas is safe and feasible, even in patients with PV/SMV involvement.

Abstract
BACKGROUND Due to varied surgical skills and the lack of an efficient rating system, we developed Surgesture based on elementary functional surgical gestures performed by surgeons, which could serve as objective metrics to evaluate surgical performance in laparoscopic cholecystectomy (LC). METHODS We defined 14 LC basic Surgestures. Four surgeons annotated Surgestures among LC videos performed by experts and novices. The counts, durations, average action time, and dissection/exposure ratio (D/E ratio) of LC Surgestures were compared. The phase of mobilizing hepatocystic triangle (MHT) was extracted for skill assessment by three professors using a modified Global Operative Assessment of Laparoscopic Skills (mGOALS). RESULTS The novice operation time was significantly longer than the expert operation time (58.12 ± 19.23 min vs. 26.66 ± 8.00 min, P < 0.001), particularly during MHT phase. Novices had significantly more Surgestures than experts in both hands (P < 0.05). The left hand and inefficient Surgesture of novices were dramatically more than those of experts (P < 0.05). The experts demonstrated a significantly higher D/E ratio of duration than novices (0.79 ± 0.37 vs. 2.84 ± 1.98, P < 0.001). The counts and time pattern map of LC Surgestures during MHT demonstrated that novices tended to complete LC with more types of Surgestures and spent more time exposing the surgical scene. The performance metrics of LC Surgesture had significant but weak associations with each aspect of mGOALS. CONCLUSION The newly constructed Surgestures could serve as accessible and quantifiable metrics for demonstrating the operative pattern and distinguishing surgeons with various skills. The association between Surgestures and Global Rating Scale laid the foundation for establishing a bridge to automated objective surgical skill evaluation.

Abstract
AIM PTEN-induced putative kinase 1 (PINK1) and Parkin E3 ubiquitin-protein ligase (Parkin) are critical for immune and inflammatory regulation in health and disease. PINK1 and Parkin have been confirmed to be involved in the progression of apical periodontitis by affecting mitophagy-related osteoblast apoptosis; however, the expression of PINK1 and Parkin in macrophages, one of the most important cells in apical periodontitis, remains unknown. This study aimed to investigate the expression of PINK1 and Parkin in human apical periodontitis lesions, as well as their possible localization in macrophages. METHODOLOGY Thirty-seven human periapical tissues, including periapical granulomas (PGs, n=12), radicular cysts (RCs, n=11), and healthy gingival tissues (n=14) were examined. The inflammatory infiltrates of lesions were evaluated by haemotoxylin staining, and the expression of PINK1 and Parkin was detected by immunohistochemistry. Double immunofluorescence was used to explore the colocalization of microtubule-associated protein 1 light chain 3 (LC3) and TOMM20, as well as the localization of PINK1 and Parkin, in macrophages of human apical periodontitis lesions. The ultrastructural morphology of mitochondria in human apical periodontitis lesions was visualized by transmission electron microscopy (TEM). Data were analyzed by one-way ANOVA with Student-Newman-Keul's test and Mann-Whitney test. P < 0.05 was considered statistically significant. RESULTS Immunohistochemistry demonstrated a significantly higher expression of PINK1 and Parkin proteins in human apical periodontitis lesions than in healthy gingival tissues (P < 0.0001), but no significant difference was demonstrated between PGs and RCs (P > 0.05). The higher expression of LC3 and the presence of more LC3-TOMM20 double-positive cells were also observed in human apical periodontitis. Double-labeling analysis of PINK1, Parkin, and LC3 with CD68 indicated that macrophage mitophagy might be present in the progression of human apical periodontitis. Finally, the results of TEM morphological analysis revealed the appearance of double-membraned mitophagosomes and vacuolated mitochondria in macrophage-like cells of apical periodontitis lesions. CONCLUSIONS Our findings indicated that PINK1 and Parkin proteins were highly expressed in clinical apical periodontitis lesions.
