Abstract
Chronic and progressive destruction/damage of the periodontal tissues resulted from periodontitis is the leading cause of tooth loss in adults. Traditional periodontal therapies such as scaling and root planning or flap surgery have demonstrated effective in controlling local inflammation and in suppressing/arresting the disease progression of periodontitis. However, those infection control measures cannot help to regenerate lost periodontal tissues to a statistically or clinically significant degree. Although some successes regarding the reduction of the intrabony defect and maintenance of the periodontal homeostasis have been achieved in periodontal regenerative procedures, comprising but not limited to guided tissue regeneration (GTR) or bone grafting technique, the restorative effectiveness of the architecture and function of the lost or injured tissues is far from our clinical expectation. The use of the concept, technique, and method of tissue engineering for periodontal regeneration is a hotspot and animal studies have shown interesting outcomes in terms of functional regeneration of lost/damaged support tissues in the periodontium, including alveolar bone, periodontal ligament, and cementum. However, numerous issues need to be addressed before those regenerative approaches can be responsibly transformed to novel clinical therapies. Recently, paradigm that induces homing of host stem cells to site of the periodontium and encourage the body's innate capability to repair is a new research field termed endogenous regeneration. Given that endogenous regenerative technique avoids ex-vivo cell culture and transplantation, it should be relatively easier to be used in the treatment of clinical patients. Due to the limited oral microenvironment and harsh periodontal local condition for tissue regeneration, as well as poor understanding of periodontal regenerative biology, there is still a long way ahead to explore new effective, practical, and economical therapies to save and protect natural tooth and for combating highly prevalent periodontal disease.

Abstract
INTRODUCTION Immune checkpoint inhibitor therapy is a highly promising strategy for clinical treatment of cancer. Among these inhibitors, ipilimumab stands out for its ability to induce cytotoxic T cell proliferation and activation by binding to CTLA-4. However, ipilimumab also gives rise to systemic immune-related adverse effects and tumor immune evasion, limiting its effectiveness. OBJECTIVES We developed IFNγ-ipilimumab and confirmed that the addition of INF-γ does not alter the fundamental properties of ipilimumab. RESULTS IFNγ-ipilimumab can be activated by matrix metalloproteinases, thereby promoting the IFNγ signaling pathway and enhancing the cytotoxicity of T cells. In vivo studies demonstrated that IFNγ-ipilimumab enhances the therapeutic effect of ipilimumab against colorectal cancer by increasing CD8+ and CD4+ lymphocyte infiltration into the tumor area and inducing MHC-I expression in tumor cells. Mice treated with IFNγ-ipilimumab showed higher survival rates and body weight, as well as lower CD4+ and CD8+ lymphocyte activation rates in the blood and reduced organ damage. CONCLUSION IFNγ-ipilimumab improved the effectiveness of ipilimumab while reducing its side effects. It is likely that future immunotherapies would rely on such antibodies to activate local cancer cells or immune cells, thereby increasing the therapeutic effectiveness of cancer treatments and ensuring their safety.

Abstract
Objective: To investigate the effects of Porphyromonas gingivalis derived outer membrane vesicles (Pg OMV) on osteoclast differentiation of macrophages and its underlying mechanisms. Methods: The morphology and the size distribution of Pg OMV were analyzed by transmission electron microscopy and nanoparticle tracing analysis, respectively. The osteoclast precursors were treated with 1, 3 and 10 mg/L Pg OMV (1, 3 and 10 mg/L OMV treatment group) or phosphate buffer solution (PBS)(control group). The formation of osteoclasts was analyzed by tartrate-resistant acid phosphase (TRAP) staining and F-actin staining and real-time quantitative PCR (RT-qPCR) were used to detect the expression of Fos and matrix metallopeptidase 9 (MMP9). Polymyxin B (PMB) was used to block lipopolysaccharide (LPS) and then Pg OMV was used to treat osteoclast precursor (PMB-OMV treatment group), and OMV treatment group was used as control. TRAP and F-actin staining were used to observe the formation of osteoclasts and actin rings. The effect of Pg OMV on the expression of Toll-like receptor (TLR) 2 and TLR4 in preosteoclasts was detected by Western blotting. The osteoclast precursors were pretreated with 10, 50, 100 and 200 μmol/L C29, an inhibitor of TLR2, and then treated with Pg OMV(OMV+10, 50, 100 and 200 μmol/L C29 treatment group) and OMV treatment group without C29 pretreatment was control. TRAP and F-actin staining were used to observe the formation of osteoclasts and actin rings. The osteoclast precursor cells were treated with OMV (OMV treatment group) and OMV incubated with PMB (PMB-OMV treatment group) and the expression of TLR2 in osteoclast precursor was detected by Western blotting. Results: Pg OMV showed classical vesicular structures, and the average particle size of Pg OMV were 179.2 nm. A large number of actin rings were observed in the 3 and 10 mg/L OMV treatment groups. The percentages of TRAP-positive osteoclast area in 3 mg/L OMV treatment group [(22.6±2.1)%] and 10 mg/L OMV treatment group [(32.0±2.3)%] were significantly increased compared with control group [(4.9±0.5)%] (P<0.001). Compared with the control group (1.000±0.029), the mRNA relative expression of Fos in 3 mg/L OMV treatment group (1.491±0.114) and 10 mg/L OMV treatment group (1.726±0.254) was significantly increased (P=0.013, P=0.001). Compared with the control group (1.007±0.148), the mRNA relative expression of MMP9 in the group of 10 mg/L OMV (2.232±0.097) was significantly increased (P<0.001). Actin ring formation was less in PMB-OMV treatment groups than in OMV treatment groups. The proportion of TRAP-positive osteoclasts area [(14.8±3.8)%] in PMB-OMV treatment group was significantly lower than OMV treatment group [(31.5±6.7) %] (P=0.004). The relative expression of TLR2 in OMV treatment group (1.359±0.134) was significantly higher than that in the control group (1.000±0.000) (t=4.62, P=0.044). Compared with the OMV treatment group [(29.4±1.7)%], 50, 100 and 200 μmol/L C29 significantly decreased the formation of osteoclasts [(24.0±1.7)%, (18.5±2.1)%, (9.1±1.3) %] (P=0.026, P<0.001, P<0.001). TLR2 protein expression in PMB-OMV group (0.780±0.046) was significantly lower than that in OMV group (1.000±0.000)(t=8.32, P=0.001). Conclusions: Pg OMV can promote osteoclast differentiation by carrying LPS, TLR2 plays an important role in Pg OMV mediated osteoclast differentiation.

Abstract
Due to the limitations of eruption time and space, third molars (M3s) are often impacted and induce a variety of oral diseases, bringing adverse effects on the health of their adjacent second molars (M2s). For a long time, a large number of studies have focused on the harm of impacted M3s (I-M3s) to the health of their adjacent teeth, while less attention has been paid to nonimpacted M3s (N-M3s) that have already erupted. In recent years, however, a growing number of studies and evidences have shown that the existence of N-M3s is also an important risk factor for various diseases of their adjacent teeth, whose hazard has not been taken seriously by dentists and patients. Based on the latest results of both domestic and international researches as well as our group, this review summarizes and explains the effects of N-M3s on the periodontal homeostasis and periodontal health of adjacent M2s, so as to provide reference for clinical decision-making of N-M3s and the healthy maintenance of their adjacent teeth.

Abstract
Exosomal microRNAs (miRNAs) are novel, non-invasive biomarkers for facilitating communication and diagnosing cancer. However, only a few studies have investigated their function and role in the clinical diagnosis of breast cancer. To address this gap, we established a stable cell line, MDA-MB-231-CD63-RFP, and recruited 112 female participants for serum collection. We screened 88 exosomal miRNAs identified through microarray analysis of 231-CD63 and literature screening using real-time PCR; only exosomal miR-92b-5p was significantly increased in patients with breast cancer. It had a significant correlation with stage and discriminated patients from the control with an AUC of 0.787. Exosomal miR-92b-5p impacted the migration, adhesion, and spreading ability of normal human mammary epithelial recipient cells through the downregulation of the actin dynamics regulator MTSS1L. In clinical breast cancer tissue, the expression of MTSS1L was significantly inversely correlated with tissue miR-92b-5p, and high expression of MTSS1L was associated with better 10-year overall survival rates in patients undergoing hormone therapy. In summary, our studies demonstrated that exosomal miR-92b-5p might function as a non-invasive body fluid biomarker for breast cancer detection and provide a novel therapeutic strategy in the axis of miR-92b-5p to MTSS1L for controlling metastasis and improving patient survival.

Abstract
Objective This study aimed to evaluate three-dimensional (3D) negative-contrast CT cholangiopancreatography (nCTCP) image quality using dual-energy CT (DECT) with iterative reconstruction (IR) technique in patients with pancreatobiliary dilatation compared with single-energy CT (SECT). Methods Of the patients, 67 and 56 underwent conventional SECT (SECT set) and DECT with IR technique (DECT set), respectively. All patients were retrospectively analyzed during the portal phase to compare objective image quality and other data including patient demographics, hepatic and pancreatic parenchymal enhancement, noise, and attenuation difference (AD) between dilated ducts and enhanced hepatic parenchyma, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and CT volume dose index (CTDIvol). Two radiologists used the five-point Likert scale to evaluate the subjective image quality of 3D nCTCP regarding image noise, sharpness of dilated ducts, and overall image quality. Statistical analyses used the Mann-Whitney U test. Results No significant difference in patient demographics in either CT set was showed during objective evaluation (p > 0.05). However, higher hepatic and pancreatic parenchymal enhancement, AD, SNR, and CNR and lower hepatic and pancreatic noise (p < 0.005) as well as CTDIvol (p = 0.005) on DECT than on SECT were observed. Higher mean grades on DECT than on SECT were showed for image noise (4.65 vs 3.92), sharpness of dilated ducts (4.52 vs 3.94), and overall image quality (4.45 vs 3.91; p < 0.001), respectively during subjective evaluation. Conclusion A higher overall image quality and lower radiation dose on 3D nCTCP can be obtained by DECT with IR technique than with conventional SECT in patients with pancreatobiliary dilatation.

Abstract
BACKGROUND/AIM The role of postoperative radiotherapy (RT) combined with chemotherapy (CT) for lymph node-positive (LN+) triple-negative breast cancer (TNBC) remains controversial. SUV39H1-mediated epigenetic regulation is associated with cancer cell migration, invasion, metastasis, and treatment resistance. This study aims to identify the role of SUV39H1 in TNBCs. MATERIALS AND METHODS Overall, 498 TNBCs with SUV39H1 RNA-seq profiles were retrieved from TCGA-BRCA and analyzed; the X-tile algorithm was used to stratify the population into low, intermediate, and high SUV39H1. Furthermore, we performed an in vitro clonogenic cell survival assay using the MDA-MB-231 cell line to assess the effects of SUV39H1 on cellular responses. RESULTS The results showed that SUV39H1 was significantly higher in TNBC than normal tissue and luminal subtype breast cancer. Notably, SUV39H1 is significantly expressed in the basal-like 1 (BL1) and immunomodulatory (IM) subgroups, compared to other subtypes. Compared to patients with a low or medium expression of SUV39H1, omitting RT only worsens disease-free survival (DFS) in those with high SUV39H1 expression. The experimental results showed SUV39H1 was suppressed by si-SUV39H1, and SUV39H1 knockdown in MDA-MB-231-IV2-1 cells enhanced the cellular toxicity of doxorubicin and paclitaxel. CONCLUSION Targeting SUV39H1 may provide a potential guiding indication of omitting RT to avoid over-treatment and chemosensitivity for TNBC.

Abstract
Nonimpacted third molars (N-M3s) refer to the third molars (M3s) that completely erupt and reach the occlusal plane without rotation. Although the removal of unerupted M3s in young adults is generally approved by most dentists, the decision on removal or retention of N-M3s remains challenging as a result of unawareness of the potential harm of N-M3s. Recent studies suggested that N-M3s were associated with deteriorated effects to the health of adjacent teeth, including higher risks of caries and alveolar bone resorption. Therefore, regular monitoring and early clinical decision on N-M3s are essential to reduce the risks of adverse effects on adjacent teeth. This review is structure to give a comprehensive overview of the negative impact of N-M3s to the adjacent teeth, in order to provide rational guidelines for clinical decision-making of N-M3s.

Abstract
Triple-negative breast cancer (TNBC) is characterized by the loss of expression of several biomarkers, which limits treatment strategies for the disease. In recent years, immunotherapy has shown promising results in the treatment of various tumors. Emerging evidence demonstrated that TNBC is an immune-activated cancer, suggesting that immunotherapy could be a feasible treatment option for TNBC. Cytokine-induced killer (CIK) cell therapy is considered as a potential treatment for cancer treatment. However, it is still not approved as a standard treatment in the clinical setting. Our previous study demonstrated that focal adhesion kinase (FAK) plays important role in regulating the sensitivity of TNBC cells to CIK cells. In this study, we further verify the role of FAK in regulating the immune response in vivo. Our in vitro study indicated that knockdown of FAK in TNBC cells or treat with the FAK inhibitor followed by co-culture with CIK cells induced more cell death than CIK cells treatment only. RNA-seq analysis indicated that suppression of FAK could affect several immune-related gene expressions in TNBC cells that affects the immune response in the tumor microenvironment of TNBC cells. The combination of FAK inhibitor and CIK cells significantly suppressed tumor growth than the treatment of FAK inhibitor or CIK cells alone in vivo. Our findings provide new insights into the cytotoxic effect of CIK cell therapy in TNBC treatment and indicate that the combination of CIK cell therapy with FAK inhibitors may be an alternative therapeutic strategy for patients with TNBC.

Abstract
Breast cancer (BC) is one of the most common malignancies in the world with aberrantly expressed glycans. The different types and stages still limit a comprehensive method in the prediagnosis of BC patients. In this research, a synthetic boronic acid-disulfide (BASS) probe has been developed for the two steps of O → S → N acyl transfer in glycoprotein recognition and labeling. The specificity and sensitivity of this method have been carefully studied in the case of immunoglobulin G, and the labeling efficiency was determined up to 60%. The BASS-functionalized slide is a powerful platform for monitoring the alteration of glycan patterns in human sera. Compared to the samples from healthy individuals, sera of BC patients gave specific patterns to eight lectins binding. The BASS-directed glycoprotein strategy promises a rapid sensing platform for a high-throughput screening of clinical BC samples and could be easily applied to other cancer prediagnoses.

Abstract
BACKGROUND Female cancers, including breast, cervical, uterine, and ovarian cancer, remain among the ten most common cancers among women worldwide, but the relationship between female cancers and abortion from previous studies is inconsistent. This study aimed to investigate risks of incident female cancers among women aged 20 to 45 years who underwent abortion in Taiwan compared with those who did not. METHOD A longitudinal observational cohort study was conducted using three nationwide population-based databases in Taiwan, focusing on 20- to 45-year-old women, with 10 years of follow-up. Matched cohorts were identified with propensity score 1-to-3 matching between 269,050 women who underwent abortion and 807,150 who did not. Multivariable Cox proportional hazard modeling was used for analysis after adjusting for covariates including age, average monthly payroll, fertility, diabetes mellitus, polycystic ovarian syndrome, endometrial hyperplasia, endometriosis, hormone-related drugs, and Charlson comorbidity index. RESULTS We found lower risk of uterine cancer (hazard ratio [HR]: 0.77, 95% CI: 0.70-0.85) and ovarian cancer (HR: 0.81, 95% CI: 0.75-0.88), but no significant difference in risk of breast cancer or cervical cancer, among matched abortion compared with non-abortion cohorts. Regarding subgroup analysis, cervical cancer risk was higher for parous women who underwent abortion, and uterine cancer risk was lower for nulliparous women who underwent abortion compared with non-abortion groups. CONCLUSIONS Abortion was related to lower uterine and ovarian cancer risk but was not associated with risks of incident breast cancer or cervical cancer. Longer follow-up may be necessary to observe risks of female cancers at older ages.

Abstract
BACKGROUND The current radiologic criteria for assessing intraoperative superior mesenteric-portal vein (SMPV) involvement (i.e., presence of tumor-SMPV contact >180° or venous deformity) in pancreatic ductal adenocarcinoma (PDAC) are highly specific but insufficiently sensitive. Therefore, development of improved markers for a more accurate prediction is essential. This study aimed to develop a risk score model to estimate SMPV involvement in PDAC using radiomics analysis of computed tomography (CT) images. METHODS Data from two institution-based cohorts of PDAC patients undergoing preoperative CT scans were used to develop (n = 173) and validate (n = 156) a radiomics-based risk score of SMPV involvement using clinical and imaging variables. A radiomics signature was developed based on 2436 radiomic features extracted from the semi-automatic three-dimensional segmentation ofn CT images. The SMPV involvement risk score was built using multivariate logistic regression and compared with the current radiologic criteria. RESULTS The study surgically identified SMPV involvement in 59 (34.1%) and 57(36.5 %) patients with PDAC in the development and validation cohorts, respectively. A 12-feature-based radiomics signature achieved areas under receiver operating characteristics curves (AUCs) of 0.89 or greater for estimating SMPV involvement. Multivariate regression identified the radiomics signature and SMPV deformity as associated with SMPV involvement. The risk score model had significantly improved AUC (0.928 vs. 0.768; P < 0.001) and sensitivity (84.2% vs. 66.7%; P = 0.025) in the radiologic evaluation. CONCLUSIONS The novel risk score in this study, combining radiomics signature and venous deformity, demonstrated promising performance for estimating SMPV involvement preoperatively for patients with PDAC.

Abstract
Periodontitis is the main cause of adult tooth loss, which seriously affects oral health and acts as a high-risk factor for varieties of systemic diseases. Gestational diabetes mellitus (GDM) is defined as glucose intolerance occurred or firstly identified during pregnancy. Prevalence of GDM is increasing over the past years worldwide. Besides adverse effects toward maternal and infant health in perinatal period, GDM also has long-term effects. Current studies have demonstrated that there is a bidirectional relationship between periodontitis and diabetes; however, the exact relationship between periodontitis and GDM remains elusive. In this paper, first reviewed the clinical association of periodontitis and GDM, and then discussed the underlying mechanisms of the two diseases, finally summarized the positive effect of periodontal therapy in controlling GDM. This paper will provide theoretical basis for the prevention diagnosis and therapy for the related diseases, promoting the maternal and infant health.

Abstract
BACKGROUND Vessels encapsulating tumor clusters (VETC) pattern is a novel microvascular pattern associated with poor outcomes of hepatocellular carcinoma (HCC). Preoperative estimation of VETC has potential to improve treatment decisions. PURPOSE To develop and validate a nomogram based on gadoxetate disodium-enhanced MRI for estimating VETC in HCC and to evaluate whether the estimations are associated with recurrence after hepatic resection. STUDY TYPE Retrospective. POPULATION A total of 320 patients with HCC and histopathologic VETC pattern assessment from three centers (development cohort:validation cohort = 173:147). FIELD STRENGTH/SEQUENCE A3.0 T/turbo spin-echo T2-weighted, spin-echo echo-planar diffusion-weighted, and 3D T1-weighted gradient-echo sequences. ASSESSMENT A set of previously reported VETC- and/or prognosis-correlated qualitative and quantitative imaging features were assessed. Clinical and imaging variables were compared based on histopathologic VETC status to investigate factors indicating VETC pattern. A regression-based nomogram was then constructed using the significant factors for VETC pattern. The nomogram-estimated VETC stratification was assessed for its association with recurrence. STATISTICAL TESTS Fisher exact test, t-test or Mann-Whitney test, logistic regression analyses, Harrell's concordance index (C-index), nomogram, Kaplan-Meier curves and log-rank tests. P value < 0.05 was considered statistically significant. RESULTS Pathological VETC pattern presence was identified in 156 patients (development cohort:validation cohort = 83:73). Tumor size, presence of heterogeneous enhancement with septations or with irregular ring-like structures, and necrosis were significant factors for estimating VETC pattern. The nomogram incorporating these indicators showed good discrimination with a C-index of 0.870 (development cohort) and 0.862 (validation cohort). Significant differences in recurrence rates between the nomogram-estimated high-risk VETC group and low-risk VETC group were found (2-year recurrence rates, 50.7% vs. 30.3% and 49.6% vs. 31.8% in the development and validation cohorts, respectively). DATA CONCLUSION The nomogram integrating gadoxetate disodium-enhanced MRI features was associated with VETC pattern preoperatively and with postoperative recurrence in patients with HCC. EVIDENCE LEVEL 4 TECHNICAL EFFICACY: Stage 2.

Abstract
Endocrine therapy (ET) of selective estrogen receptor modulators (SERMs), selective estrogen receptor downregulators (SERDs), and aromatase inhibitors (AIs) has been used as the gold standard treatment for hormone-receptor-positive (HR+) breast cancer. Despite its clinical benefits, approximately 30% of patients develop ET resistance, which remains a major clinical challenge in patients with HR+ breast cancer. The mechanisms of ET resistance mainly focus on mutations in the ER and related pathways; however, other targets still exist from ligand-independent ER reactivation. Moreover, mutations in the ER that confer resistance to SERMs or AIs seldom appear in SERDs. To date, little research has been conducted to identify a critical target that appears in both SERMs/SERDs and AIs. In this study, we conducted comprehensive transcriptomic and proteomic analyses from two cohorts of The Cancer Genome Atlas Breast Invasive Carcinoma (TCGA-BRCA) to identify the critical targets for both SERMs/SERDs and AIs of ET resistance. From a treatment response cohort with treatment response for the initial ET regimen and an endocrine therapy cohort with survival outcomes, we identified candidate gene sets that appeared in both SERMs/SERDs and AIs of ET resistance. The candidate gene sets successfully differentiated progress/resistant groups (PD) from complete response groups (CR) and were significantly correlated with survival outcomes in both cohorts. In summary, this study provides valuable clinical implications for the critical roles played by candidate gene sets in the diagnosis, mechanism, and therapeutic strategy for both SERMs/SERDs and AIs of ET resistance for the future.

Abstract
Objective: To explore the effects of periodontitis and inflammatory factors toward the occurrence of gestational diabetes mellitus (GDM). Methods: Pregnant women who came to the Department of Obstetrics, Northwest Women's and Children's Hospital for prenatal examinations during March to November of 2021 were invited to participate in this study. Participants with GDM who met the inclusion criteria (n=100) were assigned into the case group; while healthy participants (n=100) were assigned into the control group. Information of participants from the two groups were collected by questionnaires and periodontal statuses were clinically recorded in the meantime. Gingival crevicular fluid (GCF) and venous blood were also collected from participants of two groups to analyze the expression levels of inflammatory factors like C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, IL-8, IL-10 and IL-33. Factors different between the two groups were included in the multivariate regression analysis model to determine the risk factors of GDM. Results: The age of participants was (33.4±5.1) years in case group and (30.5±4.5) years in control group respectively, which had statistical differences (t=4.33,P<0.001). Besides, the body mass index of participants from case group was also significantly higher than control group [(28.11±3.85) kg/m2 vs. (23.31±3.15) kg/m2, t=9.65, P<0.001]. Participants with GDM had more adverse periodontal clinical parameters. Prevalence of periodontitis in GDM group was 47.0% (47/100) compared with 29.0% (29/100) in control group (χ²=6.88, P=0.009). Multivariate regression analysis results indicated that periodontitis was a critical risk factor for the occurrence of GDM (OR=1.882, P<0.001). Besides, GCF IL-8, serum TNF-α, IL-8 and IL-10 were also risk factors of GDM due to their higher expressions. Among them, TNF-α in serum (OR=2.077) and IL-8 in serum (OR=2.060) had more significant impacts (P<0.001). Conclusions: This study demonstrated that periodontitis was associated with the occurrence of GDM. Up-regulation of serum pro-inflammatory mediators leaded by local periodontal inflammatory microenvironment might play a critical role in this pathological process.

Abstract
Benign prostatic hyperplasia (BPH) is highly prevalent among older men, impacting on their quality of life, sexual function, and genitourinary health, and has become an important global burden of disease. Transurethral plasmakinetic resection of prostate (TUPKP) is one of the foremost surgical procedures for the treatment of BPH. It has become well established in clinical practice with good efficacy and safety. In 2018, we issued the guideline "2018 Standard Edition". However much new direct evidence has now emerged and this may change some of previous recommendations. The time is ripe to develop new evidence-based guidelines, so we formed a working group of clinical experts and methodologists. The steering group members posed 31 questions relevant to the management of TUPKP for BPH covering the following areas: questions relevant to the perioperative period (preoperative, intraoperative, and postoperative) of TUPKP in the treatment of BPH, postoperative complications and the level of surgeons' surgical skill. We searched the literature for direct evidence on the management of TUPKP for BPH, and assessed its certainty generated recommendations using the grade criteria by the European Association of Urology. Recommendations were either strong or weak, or in the form of an ungraded consensus-based statement. Finally, we issued 36 statements. Among them, 23 carried strong recommendations, and 13 carried weak recommendations for the stated procedure. They covered questions relevant to the aforementioned three areas. The preoperative period for TUPKP in the treatment of BPH included indications and contraindications for TUPKP, precautions for preoperative preparation in patients with renal impairment and urinary tract infection due to urinary retention, and preoperative prophylactic use of antibiotics. Questions relevant to the intraoperative period incorporated surgical operation techniques and prevention and management of bladder explosion. The application to different populations incorporating the efficacy and safety of TUPKP in the treatment of normal volume (< 80 ml) and large-volume (≥ 80 ml) BPH compared with transurethral urethral resection prostate, transurethral plasmakinetic enucleation of prostate and open prostatectomy; the efficacy and safety of TUPKP in high-risk populations and among people taking anticoagulant (antithrombotic) drugs. Questions relevant to the postoperative period incorporated the time and speed of flushing, the time indwelling catheters are needed, principles of postoperative therapeutic use of antibiotics, follow-up time and follow-up content. Questions related to complications incorporated types of complications and their incidence, postoperative leukocyturia, the treatment measures for the perforation and extravasation of the capsule, transurethral resection syndrome, postoperative bleeding, urinary catheter blockage, bladder spasm, overactive bladder, urinary incontinence, urethral stricture, rectal injury during surgery, postoperative erectile dysfunction and retrograde ejaculation. Final questions were related to surgeons' skills when performing TUPKP for the treatment of BPH. We hope these recommendations can help support healthcare workers caring for patients having TUPKP for the treatment of BPH.

Abstract
Abstract
Background The forkhead protein FOXO3a, the member of the forkhead box O (FOXO) transcription factors, controls a wide spectrum of carcinogenesis, therapy response and progression in human cancer. Emerging evidence suggest that phosphorylation of FOXO3a by ERK and p38 at Serine 294 induces its nuclear localization or exclusion to the cytosol, therefore regulating FOXO3a transcriptional activity and consequently promoting cell proliferation and tumorigenesis. Several proteins regulated by FOXO3a, such as MMP-2,9 and 13, are involved in metastasis. We aim to explore the potential role of p-ser294-FOXO3a and MMPs, and interplay between both in breast cancer. Materials and Methods Paraffin-embedded tissue microarrays from 350 breast cancer patients were enrolled. Immunohistochemical analysis was performed, and the expression patterns of p-ser294-FOXO3a, MMP-2, MMP-9, MMP-13 were categorized by semiquantitative method and further correlated with the clinicopathological parameters using the x2 test. Survival curves were calculated using the Kaplan-Meier method, while the significance was determined by log rank test. The biological impacts and underlying mechanisms of p-ser294-FOXO3a were analyzed by transwell assay, RT-PCR, western blotting immunofluorescence staining. co-immunoprecipitation (Co-IP) and chromatin immunoprecipitation (ChIP) assay in breast cancer cells upon transfection with FOXO3a and FOXO3a mutant (S294A). Results Our results showed that nuclear p-Ser294-FOXO3a index was inversely correlated with tumor grade (p=0.011) and relapse (p=0.053), but positively correlated only with cytoplasmic MMP-2 intensity (p=0.010). It is noted that cytoplasmic MMP-2 intensity was positively correlated with tumor grade (p=0.032) and size (p=0.028). Intriguingly, decreased nuclear p-Ser294-FOXO3a index was significantly associated with an improved overall survival rate (p=0.004) and of those patients bearing high MMP-2 staining (p<0.001) or negative ER status (p=0.006), and those receiving hormone therapy (HT) (p=0.030) or chemotherapy (p=0.001). Ectopic FOXO3a overexpression increased invasion rate which was inhibited by tamoxifen (TAM) in only ER-positive MCF-7 cells. In addition, TAM inhibited the invasion rates of ERα-negative MDA-MB-231 cells when co-expressed FOXO3a and ERα, and Ser294Ala-FOXO3a mutant (S294A) is incompetent for TAM-mediated suppression of invasion. Real time qPCR showed that TAM decreased FOXO3a-induced MMP-2 mRNA expression in MCF-7 cells and in MDA-MB-231 cells co-expressed with ERα. Co-immunoprecipitation and immunofluorescent staining showed that Ser294 phosphorylation of FOXO3a might be essential for its nuclear localization and protein-protein interaction with ERα in response to TAM. Conclusion The present study highlights that the real index of nuclear p-ser294-FOXO3a can predict a better survival rate and treatment response of HT and chemotherapy in breast cancer. Furthermore, the specific interplay among p-ser294-FOXO3a, ERα, and MMP-2 might be involved in breast cancer metastasis and treatment response. A better understanding of the underlying mechanism may improve the treatment strategy of specific breast cancer subtype.

Abstract
Objective: To analyze the clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) and COPD overlapping obstructive sleep apnea hypopnea syndrome (overlap syndrome), and to study the relationship between overlap syndrome and cardiovascular diseases. Methods: A total of 126 stable COPD patients admitted to the Respiratory Department of Peking University Third Hospital from September 2016 to October 2018 were included in this study, including 112 males and 14 females, ranging in age from 48 to 89 years, with a median of 67 years. With apnea hypopnea index (AHI) 5 times/h for the cutoff value, we classified the patients into a simple COPD group (31 cases) and an overlap syndrome group (95 cases), and compared the patients' demographic characteristics, respiratory symptoms, lung function, the incidence of cardiovascular events and the cardiac function with echocardiography (E/e'), left atrium diameter (LAD) and left ventricular ejection fraction (LVEF), by using independent-samples T test and chi-square test. Results: There were no statistically significant differences in demographic characteristics, respiratory symptoms, pulmonary function, cardiac function between COPD patients and overlap syndrome patients, but significant differences in blood oxygen level at night and left ventricular mass index(LVMI) between these groups (P=0.014,P<0.001,P<0.001,P<0.001, P=0.047, respectively) were observed. By comparing the severe sleep apnea hypopnea syndrome (AHI≥30) with sleep apnea hypopnea syndrome patients(AHI<30), there were statistically significant differences in echocardiographic indicators, among which there were statistically significant differences in E/e'(P=0.013), LAD(P=0.006), LVMI (P=0.051) and LVEF (P=0.030).There were also significant differences in the history of coronary heart disease and congestive heart failure between the two groups (P=0.025, P<0.001). After dividing the patients with overlap syndrome by mild, moderate and severe severity, E/e' and LAD were significantly correlated with severity (P=0.045, P=0.011). In terms of blood oxygen level at night, there was a significant correlation between average blood oxygen saturation at night and E/e', LAD, and LVMI (r=-0.195, P=0.033; r=-0.197, P=0.030; r=-0.195, P=0.044); moreover, there was also a significant correlation between the ratio of blood oxygen≤90% and LAD (r=0.209, P=0.021). In the multiple linear regression model, E/e' increased by 0.070 on average for each unit increase in AHI, and 0.084 on average for each unit increase in oxygen desaturation index (ODI). Conclusions: Patients with COPD overlapping severe sleep apnea hypopnea syndrome showed worse left diastolic function and higher risk of congestive heart failure and coronary heart disease compared with the patients with COPD alone. In addition, the degree of impairment of left heart diastolic function was associated with the severity of COPD overlapping sleep apnea hypopnea syndrome. The higher the AHI and the ODI became, the more severe the left heart diastolic restriction and structures changed.

Abstract
BACKGROUND This study compared the recurrence risk of single versus dual adjuvant radiotherapy (RT) and hormonal therapy (HT) following breast-conserving surgery (BCS) in patients with hormone receptor-positive ductal carcinoma in situ (DCIS). METHODS This retrospective cohort study used the Taiwan Cancer Registry database linking to the Taiwan National Health Insurance data from 2011 to 2016. We compared the recurrence risk between BCS-based regimens in Cox regressions and presented as adjusted hazard ratio (HR) and 95% confidence interval (95%CI). RESULTS The 1,836 study cohort with a low-to-intermediate risk of recurrence was grouped into BCS alone (6.1%), BCS+RT (6.2%), BCS+HT (23.4%) and BCS+HT+RT (64.3%) according to the initial treatments. During the follow-up (median: 3.3 years), the highest 5-year recurrence-free survival rate was in BCS+RT (94.1%) group and followed by BCS+HT+RT (92.8%), BCS+HT (87.4%) and BCS alone (84.9%). Of the single adjuvant therapies, RT was more effective than HT. Both BCS+HT (HR: 1.52, 95%CI: 0.99-2.35) and BCS+RT (HR: 1.10, 95%CI: 0.50-2.41) did not significantly increase recurrence risk comparing against the BCS+HT+RT group. CONCLUSION Single adjuvant demonstrated a similar subsequent recurrence risk with dual adjuvant. This study supports the proposition to de-escalate adjuvant treatments in patients with low-to-intermediate risk of DCIS recurrence.

Abstract
Triple-negative breast cancer (TNBC) remains a significant clinical challenge because of its high vascularity and metastatic and recurrent rates. Tumor angiogenesis is considered an important mediator in the regulation of tumor cell survival and metastasis in TNBC. Angiogenesis is induced by the binding of vascular endothelial growth factor to vascular endothelial growth factor receptor 2 (VEGFR2). Focal adhesion kinase (FAK) plays an important role in regulating various cell functions in normal and cancer cells. Previous studies have focused on investigating the function of endothelial FAK in tumor cell angiogenesis. However, the association between tumor FAK and VEGFR2 in tumor angiogenesis and the possible mechanisms of this remain unclear. In this study, we used a public database and human specimens to examine the association between FAK and VEGFR2. At the same time, we verified the association between FAK and VEGFR2 through several experimental methods, such as quantitative real-time polymerase chain reaction, Western blotting, and next-generation sequencing. In addition, we used the endothelial cell model, zebrafish, and xenograft animal models to investigate the role of FAK in TNBC angiogenesis. We found that FAK and VEGFR2 were positively correlated in patients with TNBC. VEGFR2 and several other angiogenesis-related genes were regulated by FAK. In addition, FAK regulated VEGFR2 and VEGF protein expression in TNBC cells. Functional assays showed that FAK knockdown inhibited endothelial tube formation and zebrafish angiogenesis. An animal model showed that FAK inhibitors could suppress tumor growth and tumor vascular formation. FAK promotes angiogenesis in TNBC cells by regulating VEGFR2 expression. Therefore, targeting FAK could be another antiangiogenic strategy for TNBC treatment.

Abstract
This study aimed to investigate the effectiveness of neoadjuvant chemotherapy in patients with breast cancer in different age groups and evaluate the impact of age group on survival outcome according to different treatment responses. Data were retrospectively collected from the cancer registry database of Kaohsiung Medical University Hospital in Taiwan under an approved protocol. Overall, 96 elder patients (aged >50 years) and 96 younger controls (aged ≤50 years) who received neoadjuvant chemotherapy and breast surgical treatment were examined after 1:1 matching. Logistic regression analysis was used to investigate the effectiveness of treatment response in patients of different age groups. Additionally, the Kaplan-Meier estimator and log-rank test were performed to evaluate the effect of age group and treatment response on disease-free and overall survival (OS). Although no direct significant association was found between age group and treatment response, several significant results were found in treatment response stratification analysis. Among 16 pathological complete response (pCR) patients, elder patients showed significantly greater 5-year disease-free survival (DFS) than younger patients (DFS rate, 85.7% vs. 0%, p = 0.041). However, in 176 non-pCR patients, elder patients showed poor DFS compared to younger patients (DFS rate, 16.6% vs. 32.3%; log-rank test, p = 0.031). With limited sample size and study design, our study results demonstrate that patients aged >50 years who achieved pCR after neoadjuvant chemotherapy could obtain better survival outcome than younger patients. However, the younger patients showed no survival benefits regardless of pCR status.

Abstract
In Western countries, breast cancer tends to occur in older postmenopausal women. However, in Asian countries, the proportion of younger premenopausal breast cancer patients is increasing. Increasing evidence suggests that the gut microbiota plays a critical role in breast cancer. However, studies on the gut microbiota in the context of breast cancer have mainly focused on postmenopausal breast cancer. Little is known about the gut microbiota in the context of premenopausal breast cancer. This study aimed to comprehensively explore the gut microbial profiles, diagnostic value, and functional pathways in premenopausal breast cancer patients. Here, we analyzed 267 breast cancer patients with different menopausal statuses and age-matched female controls. The α-diversity was significantly reduced in premenopausal breast cancer patients, and the β-diversity differed significantly between breast cancer patients and controls. By performing multiple analyses and classification, 14 microbial markers were identified in the different menopausal statuses of breast cancer. Bacteroides fragilis was specifically found in young women of premenopausal statuses and Klebsiella pneumoniae in older women of postmenopausal statuses. In addition, menopausal-specific microbial markers could exhibit excellent discriminatory ability in distinguishing breast cancer patients from controls. Finally, the functional pathways differed between breast cancer patients and controls. Our findings provide the first evidence that the gut microbiota in premenopausal breast cancer patients differs from that in postmenopausal breast cancer patients and shed light on menopausal-specific microbial markers for diagnosis and investigation, ultimately providing a noninvasive approach for breast cancer detection and a novel strategy for preventing premenopausal breast cancer.

Abstract
Despite evidence that breast cancer screening effectively diagnoses and treats cancer through early detection, mammography use remains low in Taiwan. We applied the health belief model (HBM) and the knowledge-attitude-behavior (KAB) model as theoretical frameworks to examine factors associated with mammography uptake among women aged 45-69 years in Taiwan. A cross-sectional survey January-July 2018 was conducted of women aged 45-69 years in five southern Taiwan health institutions. Survey questionnaires included demographics, HBM constructs, and health knowledge regarding breast cancer and screening. Multivariable logistic regression models explored the mediation effects of HBM constructs between health knowledge and mammography use. The final analytical sample included 621 women; 67 did not receive mammography and 554 received mammography. When the regression model was adjusted only for demographic factors, women with adequate health knowledge were more likely to undergo mammography (AOR = 2.321, 95%CI = 1.141-3.809); in regression models including health knowledge and HBM constructs, the likelihood effect of health knowledge declined and became insignificant (AOR = 1.711, 95%CI = 0.985-2.972), indicating potential mediation effects between health knowledge and up-to-date mammography use. Overall, based on the HBM and the KAB theoretical framework, our data support that health belief played a substantial mediating role in the association between health knowledge and mammography uptake, in particular perceived barriers and cues to action in the HBM, which were modifying factors of health beliefs. Therefore, to improve mammography uptake, it may be helpful to design educational model-based interventions through tackling those modifiable perceived barriers and enhancing the intensity of external cues to action.

Abstract
Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype and exhibits an overall poor outcome. Due to the lack of targeted therapy, conventional systemic chemotherapy has been the main strategy for the treatment of TNBC. Further evidence has shown that combining radiation with chemotherapy is also a suitable treatment based on DNA repair deficiencies in patients with TNBC. However, the preferred treatment for metastatic TNBC remains unclear. Therefore, identification of biomarkers is an unmet need in personalized therapy for TNBC. RNF8 (ring finger protein 8) is a ubiquitin ligase implicated in TNBC metastasis; however, its role in TNBC pathogenesis is unclear. The purpose of the present study was to investigate the roles of the RNF8-CDH1(Cadherin 1) axis in node-positive TNBC patients. We found that the RNF8high/CDH1low index was significantly higher in patients with TNBC than in patients without TNBC. Furthermore, patients with an RNF8high/CDH1low index displayed poorer outcomes than those with an RNF8low-medium/CDH1medium-high index. Notably, as compared to patients with an RNF8low-medium/CDH1medium-high index, those with an RNF8high/CDH1low index had a poorer survival rate with chemotherapy treatment alone. The combination of radiation and chemotherapy resulted in a better survival rate than chemotherapy alone in patients with an RNF8high/CDH1low index. Taken together, the RNF8high/CDH1low index not only functions as a prognostic and therapeutic marker but may also act as a target in the development of anti-cancer agents for patients with TNBC.

Abstract
BACKGROUND The rates of aesthetic breast augmentation have risen substantially in Asia. Outcomes of various breast augmentation approaches in Asia have not been comprehensively studied. In the past, the inframammary approach to breast augmentation was not popular because of conspicuous scarring. In this article, the authors review academic articles related to the use of an inframammary incision for breast augmentation in Asian women and present our recommendations for the available techniques. METHODS A literature search was performed for articles published after 2015 on Asian women with augmentation mammoplasty describing techniques, incision sites, outcomes, and complications. The search was performed using the MEDLINE, Embase, and Cochrane databases. We also included our own technique to demonstrate the outcome of augmentation mammoplasty through inframammary incision. RESULTS Eight articles satisfied our inclusion criteria. Evidence indicates that with proper preoperative design and surgical techniques, scarring resulting from the inframammary approach is not inferior to that resulting from the transaxillary approach in Asian patients. Long-term satisfaction with the inframammary approach to breast augmentation is high in Asian patients.Eight articles reported the outcomes of 1168 women receiving breast augmentation. Inframammary incisions were used in 45.29% of patients (529 patients). After the 2015 publication of Zelken's review paper on Asian breast augmentation, the rate of inframammary incisions increased from 3.1% to 45.29%. CONCLUSIONS With precise design of the new inframammary fold, accurate wound suture fixation, and postoperative scar care, the inframammary approach to breast augmentation offers optimal operative visualization, reduced pain, fewer complications, and desirable esthetic outcomes even in Asian patients. This study demonstrates that the percentage of inframammary fold approach of Asian esthetic mammoplasty grows rapidly after 2015.

Abstract
Abstract
Background:In 2017, there are more than 14,000 cases of newly diagnosed breast cancer in Taiwan. With the popularity of early screening policy and social-awareness, the proportion of early breast cancer has increased significantly in the last decades. For the high risk group with early breast cancer, adjuvant systemic chemotherapy could provide lower breast cancer recurrence rate and better overall survival rate. In Taiwan, every citizen must join the National Health Insurance (NIH), and the NIH would cover the whole expanse of adjuvant chemotherapy. Theoretically, all breast cancer patients could receive their condign chemotherapy regardless of their social economic status. The optimal initiation timing of adjuvant chemotherapy is undiscovered, and the effect of delay initiation is still under contestation. In this study, we try to identify the relationship between initiation time of chemotherapy and survival outcome, and different breast cancer subtypes would be analyzed separately. We also evaluate many associated factors that may delay chemotherapy initiation or survival status.Material and Methods:In this observational, populational-based study using Taiwan national breast cancer registry database, we studied 110,784 patients diagnosed with Stage I~III breast cancer between January 1, 2006 and Deccember 31, 2016. Time to chemotherapy(TCC) was defined as the days between surgery and the initial dose of adjuvant chemotherapy. We categorized patients into initiate chemotherapy within 30 days, 31~60 days, 61~90 days, and more than 91 days. The patient demography, tumor biology, lymph node status, type of breast surgery, receiving reconstructive surgery or not, radiation therapy, immunohistochemistry data (estrogen receptor, progesterone receptor, and human epidermal growth factor 2[HER2]), and we categorized patients according to different breast cancer subtypes. Univariate analysis with Kaplan-Meier method is used to evaluate TTC influence, and log-rank test is used to compare differences between groups. Multivariate logistic regression model is used to identify important factors associated with delayed chemotherapy initiation and survival.Preliminary Results:Totally 72840 patients were enrolled in this study, and the median age at initial diagnosis was 52.4 years old. Delayed wound healing and breast reconstruction are the main factors associated with delated TTC. Comparing with TTC<30 days group, TTC of 31~60 days group showed no difference in disease-free survival and overall survival, while TTC of 61~91 days group had a trend of lower disease-free survival (p=0.12). TTC more than 91 days had worse disease-free survival (HR=1.16, 95%CI=1.03~1.38) and overall survival (HR=1.23, 95%CI=1.08~1.52). We assumed initiate first chemotherapy more than 90 days as delated TTC as generally accepted in previous publications. In subgroup analysis, delayed TTC caused worse disease-free survival especially in triple negative group (HR=1.42, 95%CI=1.21~1.68) and HER2 group (HR=1.38, 95%CI=1.22~1.55).Conclusion:For breast cancer patients who assumed to receive adjuvant systemic chemotherapy, delayed in initiation of chemotherapy (more than 90 days) may result in worse outcome, especially in triple negative breast cancer and HER2 group. Besides the above preliminary result, other multivariate analysis and intergroup comparison are still ongoing. More information will reveal in SABCS 2020.

Abstract
BACKGROUND AND OBJECTIVE The aim of this study was to investigate the value of programmed death ligand 1 (PD-L1) expression as a predictive biomarker for Miller/Payne grading before neoadjuvant chemotherapy (NACT) in breast cancer. PATIENTS AND METHODS The expression of PD-L1 in pretreatment biopsies of breast cancer was assessed by immunohistochemistry in tissue microarrays. The results were analyzed using SPSS 22.0 statistical software. RESULTS Of 53 female patients, 10 (18.9%) patients had a grade 5 (G5) response, and 12 (22.6%) patients showed PD-L1 expression, including 7 (13.2%) patients with staining in tumor cells (TCs) and 8 (15.1%) patients with staining in peritumoral lymphocytes (PTLCs). Logistic regression analysis revealed that G5 response to NACT was significantly associated with TCs or PTLCs PD-L1 positivity, whether with univariate analysis (TCs PD-L1: p = 0.00, OR 20.50, 95% CI 3.11-134.94; PTLCs PD-L1: p = 0.02, OR 6.50, 95% CI 1.27-33.20) or with multivariate analysis (TCs PD-L1: p = 0.00, OR 42.23, 95% CI 3.36-530.90; PTLCs PD-L1: p = 0.02, OR 9.07, 95% CI 1.37-60.02). The same trend was found in the luminal subgroup analysis (TCs PD-L1: p = 0.02, OR 23.43, 95% CI 1.66-331.58; PTLCs PD-L1: p = 0.01, OR 47.89, 95% CI 2.47-927.41). CONCLUSION G5 response to NACT in breast cancer was significantly associated with TCs or PTLCs PD-L1-positive expression in pretreatment biopsies; it can be expected that PD-L1 will become a new independent biomarker of response to NACT in breast cancer.

Abstract
Background Developing a universal strategy to improve the specificity and sensitivity of PEGylated nanoaparticles (PEG-NPs) for assisting in the diagnosis of tumors is important in multimodality imaging. Here, we developed the anti-methoxypolyethylene glycol (mPEG) bispecific antibody (BsAb; mPEG × HER2), which has dual specificity for mPEG and human epidermal growth factor receptor 2 (HER2), with a diverse array of PEG-NPs to confer nanoparticles with HER2 specificity and stronger intensity. Result We used a one-step formulation to rapidly modify the nanoprobes with mPEG × HER2 and optimized the modified ratio of BsAbs on several PEG-NPs (Lipo-DiR, SPIO, Qdot and AuNP). The αHER2/PEG-NPs could specifically target MCF7/HER2 cells (HER2++) but not MCF7/neo1 cells (HER2+/−). The αHER2/Lipo-DiR and αHER2/SPIO could enhance the sensitivity of untargeted PEG-NPs on MCF7/HER2 (HER2++). In in vivo imaging, αHER2/Lipo-DiR and αHER2/SPIO increased the specific targeting and enhanced PEG-NPs accumulation at 175% and 187% on 24 h, respectively, in HER2-overexpressing tumors. Conclusion mPEG × HER2, therefore, provided a simple one-step formulation to confer HER2-specific targeting and enhanced sensitivity and contrast intensity on HER2 positive tumors for multimodality imaging. ![]()

Abstract
Background The undertreatment of cancer pain is a global issue although many international guidelines and various studies bloom to explore the approaches in pain management. However, there is no standard care for cancer pain in routine practices. To set up a standardized procedure for improving cancer pain management in Taiwan, the Good Pain Management (GPM) program is explored to provide treatments following the US National Cancer Care Network (NCCN) Adult Cancer Pain Guideline. Method Patients diagnosed with moderate-to-severe cancer pain were eligible and randomized into the GPM or control arm and observed the first 48 h to evaluate the effects of pain management between 2 arms. Pain control, adequacy of treatments, patient satisfaction, and quality of life (QoL) of eligible patients were analyzed. Ad hoc analyses based on the pain medication category were also conducted. Result Fifty-one patients were enrolled, with 26 and 25 assigned to the GPM and control arms, respectively. Significant differences among the GPM and control arms were found including a greater decrease in the mean numerical rating scale (NRS) score in the GPM arm (− 4.6 vs. − 2.8), a lower proportion of moderate-to-severe pain in the GPM arm (23.2% vs. 39.8%), and a higher pain management index (PMI) score in the GPM arm (0.64 points vs. 0.33 points) (all p < 0.05). Ad hoc analyses revealed that the patient subgroups using strong opioids showed better patient satisfaction in GPM arm when compared with the same subgroup in the control arm. Conclusion In summary, our study demonstrated that the implementation of a standardized pain assessment and management approach (GPM ward program) showed significant improvements on pain relief, decreased the portion of moderate-to-severe cancer pain, and increased patient satisfaction in the 1st 48 h after admission. The implementation of the GPM approach in the cancer ward may provide sooner and better improvement of cancer pain management for patients who suffered moderate-to-severe cancer pain.

Abstract
Targeted antibodies and methoxy-PEGylated nanocarriers have gradually become a mainstream of cancer therapy. To increase the anti-cancer effects of targeted antibodies combined with mPEGylated liposomes (mPEG-liposomes), we describe a bispecific antibody in which an anti-methoxy-polyethylene glycol scFv (αmPEG scFv) was fused to the C-terminus of an anti-HER2 (αHER2) antibody to generate a HER2 × mPEG BsAb that retained the original efficacy of a targeted antibody while actively attracting mPEG-liposomes to accumulate at tumor sites. HER2 ×mPEG BsAb can simultaneously bind to HER2-high expressing MCF7/HER2 tumor cells and mPEG molecules on mPEG-liposomal doxorubicin (Lipo-Dox). Pre-incubation of HER2 × mPEG BsAb with cells increased the endocytosis of Lipo-DiD and enhanced the cytotoxicity of Lipo-Dox to MCF7/HER2 tumor cells. Furthermore, pre-treatment of HER2 × mPEG BsAb enhanced the tumor accumulation and retention of Lipo-DiR 2.2-fold in HER2-high expressing MCF7/HER2 tumors as compared to HER2-low expressing MCF7/neo1 tumors. Importantly, HER2 × mPEG BsAb plus Lipo-Dox significantly suppressed tumor growth as compared to control BsAb plus Lipo-Dox in MCF7/HER2 tumor-bearing mice. These results indicate that HER2 × mPEG BsAb can enhance tumor accumulation of mPEG-liposomes to improve the therapeutic efficacy of combination treatment. Anti-mPEG scFv can be fused to any kind of targeted antibody to generate BsAbs to actively attract mPEG-drugs and improve anti-cancer efficacy. STATEMENT OF SIGNIFICANCE: Antibody targeted therapy and PEGylated drugs have gradually become the mainstream of cancer therapy. To enhance the anti-cancer effects of targeted antibodies combined with PEGylated drugs is very important. To this aim, we fused an anti-PEG scFv to the C-terminal of HER2 targeted antibodies to generate a HER2×mPEG bispecific antibody (BsAb) to retain the original efficacy of targeted antibody whilst actively attract mPEG-liposomal drugs to accumulate at tumor sites. The present study demonstrates pre-treatment of HER2×mPEG BsAb can enhance tumor accumulation of mPEG-liposomal drugs to improve the therapeutic efficacy of combination treatment. Anti-mPEG scFv can be fused to any kind of targeted antibody to generate BsAbs to actively attract mPEG-drugs and improve anti-cancer efficacy.

Abstract
Effects of the number of quantum wells (QWs) and Shockley-Read-Hall (SRH) recombination in deep-ultraviolet (DUV) light-emitting diodes (LEDs) are investigated theoretically. Simulation results show that, for DUV LEDs with high crystalline quality, light output power increases with an increasing number of QWs. As for the DUV LEDs with poor crystalline quality, light output power may decrease with an increasing number of QWs due to the deteriorated SRH recombination. The injection current density is also an important factor regarding the impact of the number of QWs. When operated at low current density, for the DUV LED with poor crystalline quality, light output power may decrease with an increasing number of QWs.

Abstract
PURPOSE Mitochondrial unfolding protein are abundant in breast cancer cells, but the mechanism by which breast cancer cells resist apoptosis is still not fully elucidated. In this study, we explored the role of mitochondrial unfolded protein response (mtUPR)-related proteins in four types of breast cancer tissues. METHODS Mitochondrial fractions were taken from four breast cancer tissues (luminal A, luminal B, Her2 -overexpression, and TNBC) and the expression of mitochondrial polyubiquitinated proteins was observed by western blot and ELISA. In addition, the expression of hsp10, hsp60, and clpp in mitochondria was observed by western blot in breast cancer tissues and adjacent tissues, and confirmed by ELISA. The expression levels of hsp10 and hsp60 were correlated with clinicopathological parameters in 114 breast cancer patients. RESULTS We found an increase in the performance of mitochondrial polyubiquitinated proteins in breast cancer tissues of luminal A, luminal B, Her2-overexpression, and TNBC. The mitochondrial hsp10, hsp60, and clpp are abundantly expressed in breast cancer tissues rather than adjacent noncancerous tissues. The expression levels of mitochondrial hsp10 and hsp60 were highest in histological grade 3 breast cancer tissues. Additionally, mitochondria with high hsp60 expression were more present in Her2-positive tumors. CONCLUSIONS We observed that mtUPR was specifically activated in breast cancer tissues but inactivated in normal mammary tissue. MtUPR had also exhibited a particular increase in Her2-overexpression tumors but not in ER- or PR-positive tumors. Taken together, we suggested that mtUPR may act as a potential candidate for developing novel Her2-overexpression breast cancer therapy.

Abstract
In the era of intensity-modulated radiotherapy (IMRT), it is important to analyse the prognostic value of deficient mismatch repair (dMMR) in nasopharyngeal carcinoma (NPC). In this study, in pretreatment biopsies of 69 patients with stage II-IVa NPC, the expression levels of MMR proteins, including MLH1, MSH2, MSH6 and PMS2, were assessed by immunohistochemistry (IHC). The median follow-up time was 37.5 months (3.1-87.4 months). 50.7% of cases (35/69) showed preserved expression of all 4 MMR proteins, which was interpreted as proficient mismatch repair (pMMR). Only 1.5% of cases (1/69) lost expression of all 4 MMR proteins, 26.1% of cases (18/69) have PMS2 loss alone and 21.7% of cases (15/69) lost expression of both PMS2 and MLH1. Thus, 49.3% of cases (34/69) lost expression of one or more MMR proteins, which was interpreted as dMMR. There was no significant difference (P > 0.05) in terms of sex, age, clinical stage, T category, N category or therapy regimens between the dMMR and pMMR groups. The multivariate Cox regression analysis revealed that dMMR was an independent significant prognostic factor for distant metastasis-free survival (DMFS) (dMMR vs pMMR: P = 0.01, HR = 0.25, 95% CI: 0.09~0.75). Therefore, NPC patients with dMMR had significantly superior DMFS compared with patients with pMMR. It can be expected that dMMR will become a new independent prognostic factor for NPC.

Abstract
Travelers are known to convey infectious diseases across international borders. After its experience with SARS, Taiwan established a comprehensive mechanism at its border to prevent the entry of infectious diseases. However, people with chronic infectious diseases, carriers with no symptoms, and those likely to be infected are not easy to identify during border screenings. Therefore, Taiwan must implement internal disease-containment measures in addition to stopping infectious disease at its borders. With increasing numbers of patients coming to Taiwan for medical examinations, medical aesthetic treatments, and medical treatments and care, the risk of acute, chronic, and contagious diseases originating from non-residents must be considered and addressed. This article was developed to discuss the role and importance of nurses in preventing transnational infectious diseases from the perspective of international medical care. In addition to showing rich nursing experience, sensitivity, and conducting the management and communication of international cases, it is also necessary to make good use of information tools for remote screening care. Taking the period of the COVID-19 outbreak as an example, several procedures have been conducted. First, online detailed history of infectious diseases and nursing evaluations are conducted before admission. Second, preparation and movement notifications are given before admission. Third, online health education and follow-up care as well as cross-unit communication and coordination are implemented. International medical nurses directly affect the quality and effectiveness of international medical treatment. As Taiwan builds up its brand as an international medical caring destination, nursing professionals should help further this trend and announce to the world: Taiwan can help! Nursing can help!

Abstract
Rationale: Increasing frequency of human exposure to PEG-related products means that healthy people are likely to have pre-existing anti-PEG antibodies (pre-αPEG Ab). However, the influence of pre-αPEG Abs on the pharmacokinetics (PK) and therapeutic efficacy of LipoDox is unknown. Methods: We generated two pre-αPEG Ab mouse models. First, naïve mice were immunized with PEGylated protein to generate an endogenous αPEG Ab titer (endo αPEG). Second, monoclonal αPEG Abs were passively transferred (αPEG-PT) into naïve mice to establish a αPEG titer. The naïve, endo αPEG and αPEG-PT mice were intravenously injected with 111in-labeled LipoDox to evaluate its PK. Tumor-bearing naïve, endo αPEG and αPEG-PT mice were intravenously injected with 111in-labeled LipoDox to evaluate its biodistribution. The therapeutic efficacy of LipoDox was estimated in the tumor-bearing mice. Results: The areas under the curve (AUC)last of LipoDox in endo αPEG and αPEG-PT mice were 11.5- and 15.6- fold less, respectively, than that of the naïve group. The biodistribution results suggested that pre-αPEG Ab can significantly reduce tumor accumulation and accelerate blood clearance of 111In-labeled LipoDox from the spleen. The tumor volumes of the tumor-bearing endo αPEG and αPEG-PT mice after treatment with LipoDox were significantly increased as compared with that of the tumor-bearing naïve mice. Conclusions: Pre-αPEG Abs were found to dramatically alter the PK and reduce the tumor accumulation and therapeutic efficacy of LipoDox. Pre-αPEG may have potential as a marker to aid development of personalized therapy using LipoDox and achieve optimal therapeutic efficacy.

Abstract
BACKGROUND Macrophage heterogeneity is the main feature of the tumour microenvironment. Breast cancer is one of the most life-threatening cancers. However, macrophage polarization patterns in different tumour stages and the importance of its relationship to human epidermal growth factor receptor 2 (HER2) in breast cancer remains highly unclear. The present study investigated the patterns of monocyte differentiation and macrophage polarization in breast cancer. METHODS Patients with breast cancer (n = 48) and healthy controls (n = 39) were prospectively recruited. The percentages and subsets of circulating macrophage-like cells were analysed by flow cytometry, and the polarization patterns of these cells in the peripheral blood of patients with breast cancer were compared with those of healthy controls. In addition, macrophage polarization patterns in different stages and HER2 status in breast cancer were investigated. RESULTS The percentages of circulating macrophages, which are defined as PM-2 K+ cells in the peripheral blood, were significantly higher in patients with breast cancer than in healthy controls. The percentages of M1-like macrophages were significantly lower, but those of M2-like macrophages were significantly higher in patients with breast cancer than in healthy controls. The percentage of M2c-like macrophages was significantly higher in advanced (stages II and III) breast cancer. However, the patterns of macrophage polarization were not associated with HER2 status in breast cancer. CONCLUSIONS Aberrant macrophage polarization was observed in breast cancer and was correlated with breast cancer stage. These quantitative data may provide new molecular biomarkers and potential therapeutic targets in breast cancer.

Abstract
The clinical management of periodontal disease is a global concern, and the regeneration of periodontal tissue defects due to periodontitis faces a huge challenge in the field of regenerative dentistry. Although conventional periodontal therapies focusing on in flammation control could stop or delay the progression of the disease, periodontal regeneration remains an elusive but laudable goal. Since late 1980s, concerted efforts have been made to accelerate and augment periodontal repair by using guided tissue regeneration (GTR), guided bone regeneration (GBR) and a wide range of other regenerative paradigms. Those advances have largely improved the clinical outcomes of periodontal therapies. In the past several years of 21st century, many progresses were made in the developments of stem cell therapy and tissue engineering, including remarkable biological discoveries in the laboratory as well as great curative successes in preclinical scenarios. The use of the principles, techniques and procedures of tissue engineering in periodontology showed great potential to regenerate new functional periodontal tissues such as alveolar bone, periodontal ligament, root cementum and finally and predictably the normal structure and functionality of the periodontium around a previously diseased tooth.

Abstract
Systemic injection of therapeutic antibodies may cause serious adverse effects due to on-target toxicity to the antigens expressed in normal tissues. To improve the targeting selectivity to the region of disease sites, we developed protease-activated pro-antibodies by masking the binding sites of antibodies with inhibitory domains that can be removed by proteases that are highly expressed at the disease sites. The latency-associated peptide (LAP), C2b or CBa of complement factor 2/B were linked, through a substrate peptide of matrix metalloproteinase-2 (MMP-2), to an anti-epidermal growth factor receptor (EGFR) antibody and an anti-tumor necrosis factor-α (TNF-α) antibody. Results showed that all the inhibitory domains could be removed by MMP-2 to restore the binding activities of the antibodies. LAP substantially reduced (53.8%) the binding activity of the anti-EGFR antibody on EGFR-expressing cells, whereas C2b and CBa were ineffective (21% and 9.3% reduction, respectively). Similarly, LAP also blocked 53.9% of the binding activity of the anti-TNF-α antibody. Finally, molecular dynamic simulation showed that the masking efficiency of LAP, C2b and CBa was 33.7%, 10.3% and −5.4%, respectively, over the binding sites of the antibodies. This strategy may aid in designing new protease-activated pro-antibodies that attain high therapeutic potency yet reduced systemic on-target toxicity.

Abstract
Monolithic stacked InGaN light-emitting diode (LED) connected by a polarization-enhanced GaN/AlN-based tunnel junction is demonstrated experimentally in this study. The typical stacked LEDs exhibit 80% enhancement in output power compared with conventional single LEDs because of the repeated use of electrons and holes for photon generation. The typical operation voltage of stacked LEDs is higher than twice the operation voltage of single LEDs. This high operation voltage can be attributed to the non-optimal tunneling junction in stacked LEDs. In addition to the analyses of experimental results, theoretical analysis of different schemes of tunnel junctions, including diagrams of energy bands, diagrams of electric fields, and current-voltage relation curves, are investigated using numerical simulation. The results shown in this paper demonstrate the feasibility in developing cost-effective and highly efficient tunnel-junction LEDs.

Abstract
Resident stem cell pools in many tissues/organs are responsible not only for tissue maintenance during physiologic turnover but also for the process of wound repair following injury. With inspiration from stem cell trafficking within the body under physiologic and pathologic conditions, recent advances have been made toward inducing stem cell mobilization and directing patients' own cells to sites of interest for treating a broad spectrum of diseases. An evolving body of work corroborates that delivering guidance cues can mobilize stem cells from the bone marrow and drive these cells toward a specific region. In addition, the transplantation of cell-friendly biomaterials incorporating certain biomolecules has led to the regeneration of lost/damaged tissue without the need for delivering cellular materials manipulated ex vivo. Recently, cell homing has resulted in remarkable biological discoveries in the laboratory as well as great curative successes in preclinical scenarios. Here, we review the biological evidence underlying in vivo cell mobilization and homing with the aim of leveraging endogenous reparative cells for therapeutic applications. Considering both the promise and the obstacles of this approach, we discuss how matrix components of the in vivo milieu can be modified to promote the native regenerative process and inspire future tissue-engineering design.
