Abstract
BACKGROUND Periprosthetic joint infection (PJI) is a significant post-arthroplasty complication for diabetic patients, with uncontrolled diabetes identified as a PJI risk factor. Taiwan's Diabetes Shared Care Program (DSCP) was established for holistic diabetes care. AIM To evaluate the DSCP's impact on PJI incidence and patients' medical costs. METHODS Data were analysed from Taiwan's National Health Insurance Research Database from 2010 to 2020, focusing on type 2 diabetes mellitus (DM) patients who had undergone arthroplasty. The study group involved DSCP participants, while a comparison group comprised non-participants with matched propensity scores for age, sex, and comorbidities. The primary outcome was the PJI incidence difference between the groups; the secondary outcome was the medical expense difference. FINDINGS The study group consisted of 11,908 type 2 DM patients who had arthroplasty and joined the DSCP; PJI occurred in 128 patients. Among non-participants, 184 patients had PJI. The PJI incidence difference between the groups was statistically significant (1.07% vs 1.55%). The study group's medical costs were notably lower, regardless of PJI incidence. Multivariate regression showed higher PJI risk in patients in comparison group, aged >70 years, male, or who had obesity, anaemia. CONCLUSION The study indicates that DSCP involvement reduces PJI risks and decreases annual medical costs for diabetic patients after arthroplasty. Consequently, the DSCP is a recommendable option for such patients who are preparing for total joint arthroplasty.

Abstract
Objective: To observe the treatment response of a two-dose regimen of inotuzumab ozogamicin (inotuzumab), a monoclonal antibody targeting CD22, for patients with heavily treated relapsed/refractory B-cell acute lymphoblastic leukemia (R/R B-ALL), including those failed or relapsed after chimeric antigen receptor (CAR) -T-cell therapy. Methods: Pediatric and adult patients who received two doses of inotuzumab and who were evaluated after inotuzumab treatment were included. Antibody infusions were performed between March 2020 and September 2022. All patients expressed CD22 antigen as detected by flow cytometry (>80% leukemic cells displaying CD22) before treatment. For adults, the maximum dosage per administration was 1 mg (with a total of two administrations). For children, the maximum dosage per administration was 0.85 mg/m(2) (no more than 1 mg/dose; total of two administrations). The total dosage administered to each patient was less than the standard dosage of 1.8 mg/m(2). Results: Twenty-one patients with R/R B-ALL were included, including five children (<18 years old) and sixteen adults. Seventeen patients presented with 5.0% -99.0% leukemic blasts in the bone marrow/peripheral blood or with extramedullary disease, and four patients were minimal residual disease (MRD) -positive. Fourteen patients underwent both CD19 and CD22 CAR-T-cell therapy, four underwent CD19 CAR-T-cell therapy, and three underwent blinatumomab therapy. Eleven patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). After inotuzumab treatment, 14 of 21 patients (66.7% ) achieved a complete response (CR, one was MRD-positive CR), and all four MRD-positive patients turned MRD-negative. Four of six patients who failed recent CD22 CAR-T-cell therapy achieved a CR after subsequent inotuzumab treatment. Seven patients (33.3% ) demonstrated no response. Grade 1-3 hepatotoxicity occurred in five patients (23.8% ), one child with no response experienced hepatic veno-occlusive disease (HVOD) during salvage transplantation and recovered completely. Conclusion: For patients with heavily treated R/R B-ALL, including those who had undergone allo-HSCT and CD19/CD22 CAR-T-cell therapy, the two-dose regimen of inotuzumab resulted in a CR rate of 66.7%, and the frequency of hepatotoxicity and HVOD was low.

Abstract
PURPOSE/OBJECTIVE(S) To assess the incidence rate of cardiac implantable electronic devices (CIED) malfunction with radiotherapy (RT) and identify factors resulting in CIED malfunction. The working hypothesis is that CIED malfunction is associated with higher photon beam energy, treatment anatomical location, device type and dose to device. MATERIALS/METHODS This retrospective review involved 441 patients with CIED treated with RT. Clinical information, RT (prescription, dose to device, beam energy, anatomical regions treated etc.) and CIED details (type, manufacturer, and device malfunction) were collected from electronic medical records. RESULTS A total of 344 patients (78%) had a permanent pacemaker (PPM), 44 patients (10%) had implantable cardioverter defibrillator (ICD), 44 patients (10%) had CRT-defibrillator (CRT-D) and 9 (2%) had cardiac resynchronization therapy-pacing (CRT-P). The median prescribed dose was 36 Gy (IQR 1.8-80 Gy). 17 out of 441 patients (3.9%) experienced an CIED malfunction event. This group had a higher prescribed median dose of 42.5 Gy (IQR 20-77 Gy) and beam energy of 14 MV (12-18 MV). None of the malfunctions resulted in clinical symptoms. Median dose to CIED was 0.28 Gy (IQR 0-3.3). No patents received dose to device ≥2 Gy. Using logistic regression, the predictors of CIED malfunction were photon beam energy use ≥10 MV (OR 5.73; 95% CI, 1.58-10.76), anatomical location of RT above the diaphragm (OR 5.2, 95% CI, 1.82-15.2), and having an ICD (OR 4.6, 95% CI, 0.75-10.2). CONCLUSION We have demonstrated that photon beam energies ≥10 MV, RT to above the diaphragm and ICD devices are significantly associated with CIED malfunction. The recorded CIED malfunctions in this study were minor malfunctions which did not result in any clinical symptoms. Stringent adherence to the local institution's CIED treatment guidelines, utilization of safety measures and careful choice of beam energy are recommended to minimize risk of symptomatic CIED malfunctions.

Abstract
The SNO+ Collaboration reports the first evidence of reactor antineutrinos in a Cherenkov detector. The nearest nuclear reactors are located 240 km away in Ontario, Canada. This analysis uses events with energies lower than in any previous analysis with a large water Cherenkov detector. Two analytical methods are used to distinguish reactor antineutrinos from background events in 190 days of data and yield consistent evidence for antineutrinos with a combined significance of 3.5σ.

Abstract
The Quarterly Reports of the Ophthalmic Hospital at Canton written by Rev. Peter Parker, an American protestant missionary in China, were serialised in The Chinese Repository from 1836 to 1850. Each report provided the number of patients treated in the corresponding period and described in detail the treatment of diseases which were difficult to deal with. However, due to historical conditions, these reports were inconsistent in terms of the disease classification standards, let alone the statistical deficiencies. This paper aims to regroup the diseases recorded in the 15 reports according to the classification from the eleventh to fifteenth report and recount the patient number of each disease systematically in different periods, with reliable historical data to support such relevant studies as the history of the Ophthalmic Hospital at Canton and the introduction of Western Medicine into China and the development of International Classification of Diseases.

Abstract
Tumour necrosis factor inhibitors (TNFis) are commonly used for treating psoriatic diseases; however, the risk of infection while receiving TNFis remains uncertain. The aim of this study was to investigate the infection risk in patients with psoriatic disease receiving TNFis. A prospectively registered systematic literature search was conducted in Medline (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and the ClinicalTrials.gov databases from inception to December 31, 2021. We included double-blind randomized controlled trials that compared TNFis or other biologics with placebo in adults with psoriasis or psoriatic arthritis. The primary outcomes included overall and serious infection risks, and secondary outcomes included upper respiratory infections and nasopharyngitis risks. The risk ratio of the dichotomous outcome was calculated using the Mantel-Haenszel method with random effects, and heterogeneity was assessed using Cochran's Q statistic and quantified using the I-squared statistic. A total of 48 studies with 15 464 patients with psoriatic diseases were included. The meta-analysis demonstrated a slightly increased overall infection risk (risk ratio = 1.09; 95% confidence interval, 1.02-1.15) but not serious infection risk (risk ratio = 0.95; 95% confidence interval, 0.61-1.49) among patients receiving TNFis. There were also no increased risks of upper respiratory infections (risk ratio = 1.10; 95% confidence interval, 0.94-1.28) or nasopharyngitis (risk ratio = 1.14; 95% confidence interval, 1.00-1.30). In subgroup analyses using the fixed effects model, only etanercept and certolizumab pegol were, respectively, associated with an increased risk of overall infection (RR = 1.14, 95% CI, 1.03-1.27) and upper respiratory infections (RR = 1.42, 95% CI, 1.02-1.98). In conclusion, evidence to date suggests an increased overall infection risk that is generally tolerable in patients with psoriatic diseases receiving TNFis. There are no increased risks of serious infections, upper respiratory infections or nasopharyngitis.

Background / Introduction
There are currently no treatments for directly improving diastolic dysfunction in heart failure with preserved ejection fraction (HFpEF). Improving myocardial relaxation via manipulating sarcomere function has great potential to unveil novel targets for treating HFpEF. Mavacamten, a small molecule inhibitor of myosin ATPase, has been developed through drug screening as a treatment for hypertrophic cardiomyopathy (HCM), and it is currently being tested in HFpEF patients. Interestingly, emerging evidence suggests that mavacamten may not only modulate contractility but may also modulate myocardial relaxation.
Purpose
The aim of this study was to investigate whether mavacamten directly modulates sarcomere mechanical properties to improve myocardial relaxation in a mouse HFpEF model.
Methods
Eight to ten weeks old adult male C57Bl/6 mice were fed with (1) standard diet or (2) high-fat diet (HFD) + L-NAME to induce HFpEF (n=10 mice/group). Cardiac function was assessed by transthoracic two-dimensional echocardiography at baseline and after 15 weeks. Mouse myofibrils (n=10-15 per animals) were obtained from control and HFpEF mice using a triton X-100-based skinning method. The contractile function of the sarcomere with or without the presence of mavacamten were investigated using a myofibril mechanical system. General myofibril mechanical parameters measured included resting and maximal tension (RT, FMAX, mN/mm2), rate constant of tension development (kACT, S-1), duration of linear relaxation phase (tLIN, mSec) and rate constant of linear and exponential phase relaxation (linear and exponential kREL, S-1). Furthermore, force production as a function of the bathing Ca2+ concentration (pCa 4.5-9.0) was measured to determine the Ca2+ sensitivity of the myofibrils.
Results
As previously reported, C57Bl/6 mice fed with HFD + L-NAME developed cardiac hypertrophy, diastolic dysfunction, exercise intolerance despite having preserved systolic function at 15 weeks. Mechanical analysis showed myofibrils isolated from HFpEF mice has mildly reduced force generation, significantly higher stiffness and elevated Ca2+ sensitivity, compared with control animals. Ex vivo treatment of mavacamten completely normalised Ca2+ sensitivity of the myofibrils from HFpEF animals. Interestingly, mavacamten treatment further accelerated the rate of linear phase relaxation (linear kREL).
Conclusion
This is the first study to characterise in detail the mechanical properties of myofibrils in a mouse HFpEF model. We demonstrated myosin ATPase inhibition using mavacamten could normalise elevated Ca2+ sensitivity as well as facilitate relaxation kinetics at the sarcomere level in HFpEF. These findings position mavacamten to be a potential therapeutic intervention for improving diastolic function in patients with HFpEF.

Abstract
OBJECTIVE Enteral nutrition (EN) is the first-choice nutritional support, as it is more in line with normal physiological processes. During EN, the major goals to achieve include accurate confirmation of the feeding tube position, monitoring the gastric residual volume, assessing gastrointestinal motility, and monitoring the nutritional status of patients. With rapid development in technology, point-of-care ultrasound (POCUS) has become a more convenient and effective technical tool for monitoring critically ill patients receiving EN. In this review, we have summarized and discussed the value of POCUS in the implementation, monitoring, and evaluation of EN therapy to provide a reference for nutritional support of critically ill patients in critical care settings. MATERIALS AND METHODS This is a narrative review. A literature search for Scopus-indexed articles was performed randomly using PubMed and MEDLINE databases as the primary sources. No specific term was used for the search. RESULTS POCUS can be used for positioning of nasogastric and nasointestinal tubes, evaluation of gastric residuals and gastrointestinal motility as well as monitoring of nutritional status. CONCLUSIONS POCUS is a real-time, highly repeatable, radiation-free, and non-invasive visual inspection technique, with high application value in assessing the nutritional status of patients receiving EN and guiding the development of further nutritional treatment plans. It is an important diagnostic and monitoring tool that can be used by the clinicians in the ICU.

Abstract
Resulting from impaired collagen turnover, fibrosis is a hallmark of adipose tissue (AT) dysfunction and obesity-associated insulin resistance (IR). Prolidase, also known as peptidase D (PEPD), plays a vital role in collagen turnover by degrading proline-containing dipeptides but its specific functional relevance in AT is unknown. Here we show that in human and mouse obesity, PEPD expression and activity decrease in AT, and PEPD is released into the systemic circulation, which promotes fibrosis and AT IR. Loss of the enzymatic function of PEPD by genetic ablation or pharmacological inhibition causes AT fibrosis in mice. In addition to its intracellular enzymatic role, secreted extracellular PEPD protein enhances macrophage and adipocyte fibro-inflammatory responses via EGFR signalling, thereby promoting AT fibrosis and IR. We further show that decreased prolidase activity is coupled with increased systemic levels of PEPD that act as a pathogenic trigger of AT fibrosis and IR. Thus, PEPD produced by macrophages might serve as a biomarker of AT fibro-inflammation and could represent a therapeutic target for AT fibrosis and obesity-associated IR and type 2 diabetes.

Abstract
Lymphoepithelial carcinoma is rare in the salivary glands, with an incidence of 0.4%. The most commonly affected site is the parotid gland, followed by the submandibular gland. Lymphoepithelial carcinoma in the sublingual gland has been reported only four times in the existing English-language literature. Such tumours are characterized by the presence of a poorly differentiated carcinoma that is surrounded and infiltrated by lymphocytes, and they are strongly associated with Epstein-Barr virus infection, patient ethnicity, and prominent radiosensitivity. Wide surgical excision combined with adjuvant therapy has been suggested as the first-choice therapeutic regimen. This report describes the case of a 34-year-old Indonesian woman who was evaluated and treated in Taipei Medical University Hospital. She had a tumour that presented as a painless swelling on the floor of the mouth. The diagnosis was confirmed by conducting an incisional biopsy, and a wide surgical excision with bilateral supraomohyoid neck dissection and free flap reconstruction was performed. The patient also underwent adjuvant chemoradiotherapy. No evidence of local recurrence or distant metastasis was detected during the 6 months of follow-up. Subsequently, the patient returned to her home country, and further follow-ups were not conducted.

Abstract
Objective: To explore the associations of platelet parameters platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) with the risk for stroke in people with different blood pressure levels. Methods: All the participants were from Dongfeng-Tongji cohort, including 38 295 retired employees from Dongfeng Motor Corporation at the first follow-up survey. After excluding participants with coronary heart disease, stroke, cancer, history of platelet influential drug use and those with missed data of platelet parameters or blood pressure or lost to follow-up, finally a total of 21 294 participants were included in this study. All the participants completed baseline questionnaires, physical examinations, clinical biochemical tests, and blood sample collection. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and the corresponding 95% confident intervals (CIs) for the associations between platelet parameters and risk for stroke in people with different blood pressure levels. Results: After a mean follow-up of 8.0 years, 1 578 participants developed incident stroke [1 266 ischemic stroke (IS) cases and 312 hemorrhagic stroke (HS) cases]. Compared with the participants with PLT<188×109/L, those with PLT≥188×109/L among hypertension cases were significantly associated with higher risks for stroke and IS (stroke: HR=1.27, 95%CI: 1.12-1.44; IS: HR=1.39, 95%CI: 1.21-1.60). Among hypertension group, compared with participants with PCT<0.165%, PCT≥0.165% were significantly associated with higher risk for stroke (HR=1.15, 95%CI: 1.01-1.30) and lower risk for HS (HR=0.70, 95%CI: 0.53-0.93); Among non-hypertension and hypertension group, PCT ≥0.165% were significantly associated with higher risks of IS (HR=1.27, 95%CI: 1.05-1.54; HR=1.31, 95%CI: 1.14-1.50). MPV and PDW were not significantly associated with risk for stroke. Risk for stroke increased significantly in hypertension cases with different platelet parameters levels compared with non-hypertension cases with lower levels of each platelet parameters. Conclusion: Higher levels of PLT and PCT could increase the risks for stroke and IS in middle-aged and elderly hypertension patients, and lower levels of PCT could decrease the risk for HS in hypertension patients.

Abstract
Endoscopic prelacrimal recess approach is a promising technique for treating various maxillary sinus diseases because it allows for adequate visualization and wide access to the entire maxillary sinus. However, the incidence of absent prelacrimal recess (PLR) has ranged from 7% to 17.5%, implying that there is a limitation for the application of EPLA in this population. Here, a male patient with concomitant Krouse T2 maxillary inverted papilloma and mycetoma presenting with unilateral nasal obstruction and blood-tinged secretion is described. The presurgical computed tomography showed no recess. By dislocating the nasolacrimal duct from the bony canal and removing the medial maxillary wall sufficiently to extend the surgical corridor; and by preserving the inferior turbinate, nasal mucosa, and nasolacrimal duct, the patient did not experience any postoperative complications. In conclusion, our modified technique may be an effective and safe strategy for treating maxillary sinus disease without prelacrimal recess.

Abstract
We report observations of gamma-ray emissions with energies in the 100-TeV energy region from the Cygnus region in our Galaxy. Two sources are significantly detected in the directions of the Cygnus OB1 and OB2 associations. Based on their positional coincidences, we associate one with a pulsar PSR J2032+4127 and the other mainly with a pulsar wind nebula PWN G75.2+0.1, with the pulsar moving away from its original birthplace situated around the centroid of the observed gamma-ray emission. This work would stimulate further studies of particle acceleration mechanisms at these gamma-ray sources.

Abstract
Cerebrospinal fluid (CSF) leak and encephalocele from the middle cranial fossa into the sphenoid sinus lateral recess (SSLR) is a rare condition. It is often associated with obesity, female sex, well-pneumatized sinus, and prolonged intracranial hypertension. Endoscopic repair has emerged as the mainstay treatment with a success rate increasing to over 90% by refining reconstruction methods and controlling intracranial pressure. Here, we describe how a female with SSLR CSF leak and encephalocele successfully managed with endoscopic transpterygoid approach and multilayered repair. The defect was closed using four indifferent tissues, including the duragen patch, sinus mucosal flaps, the middle turbinate bone, and free mucosa flap, from the inside out. The patient had an uneventful postsurgical course and remained disease-free during the 9-month follow-up. To conclude, the technique of using sinus mucosal flaps in the context of multilayered reconstruction might be a useful method to repair CSF leak.

Abstract
Ag50Cu50 films were deposited on glass substrates by a sputtering system. Effects of accumulated energy on nanoparticle formation in pulse-laser dewetting of AgCu films were investigated. The results showed that the properties of the dewetted films were found to be dependent on the magnitude of the energy accumulated in the film. For a low energy accumulation, the two distinct nanoparticles had rice-shaped/Ag60Cu40 and hemispherical/Ag80Cu20. Moreover, the absorption spectra contained two peaks at 700 nm and 500 nm, respectively. By contrast, for a high energy accumulation, the nanoparticles had a consistent composition of Ag60Cu40, a mean diameter of 100 nm and a peak absorption wavelength of 550 nm. Overall, the results suggest that a higher Ag content of the induced nanoparticles causes a blue shift of the absorption spectrum, while a smaller particle size induces a red shift.

Abstract
We report, for the first time, the long-awaited detection of diffuse gamma rays with energies between 100 TeV and 1 PeV in the Galactic disk. Particularly, all gamma rays above 398 TeV are observed apart from known TeV gamma-ray sources and compatible with expectations from the hadronic emission scenario in which gamma rays originate from the decay of π^{0}'s produced through the interaction of protons with the interstellar medium in the Galaxy. This is strong evidence that cosmic rays are accelerated beyond PeV energies in our Galaxy and spread over the Galactic disk.

Abstract
Diabetic nephropathy (DN) is primary cause of end-stage renal disease. A previous study has shown that miR-32-5p (miR-32) is highly expressed in kidney tissue during chronic allograft dysfunction with interstitial fibrosis and tubular atrophy. However, the role of miR-32-5p (miR-32) in DN is still unclear. In this study, streptozotocin-induced DN rat models and high glucose (HG)-incubated human kidney proximal tubular epithelial (HK-2) cells were established to investigate the role and underlying mechanisms of miR-32 in DN. Results of real-time PCR revealed that miR-32 levels were greatly increased in DN rats and HG-incubated HK-2 cells. Downregulation of miR-32 effectively relieved HG-induced autophagy suppression, fibrosis, epithelial-mesenchymal transition (EMT) and inflammation in HK-2 cells. Besides, miR-32 overexpression significantly down-regulated the expression of mothers against decapentaplegic homolog 7 (SMAD7), whereas knockdown of miR-32 markedly up-regulated the level of SMAD7. Dual-luciferase reporter gene assay confirmed that SMAD7 was a target of miR-32. Reintroduction of SMAD7 expression rescued miR-32-induced HK-2 cells autophagy suppression, EMT and renal fibrosis. Our findings indicate that miR-32 may play roles in the progression of EMT and fibrosis in DN.

Abstract
Mentoring aims to improve careers and create benefits for the participants' personal and professional lives. Mentoring can be an individual or a shared experience for a group, while the mentor's role remains the same in both models. Mentors should increase confidence, teach, inspire, and set examples, helping the mentees to mould their path, contributing to the pursuit of their personal and professional goals. This study aims to report on the experience of early-career medical physics professionals and postgraduate students participating in a global mentoring program and to assess the impact of this activity on their professional development. The objectives of this mentoring program are to develop leadership roles among young medical physicists and to provide guidance and support. An online questionnaire was administered to the mentee participants. The analysis of their responses is reported in this work and the current status of the programme was examined using a SWOT analysis. In general, the mentoring experience had a positive impact on the mentees. The mentors were found especially helpful in the decision-making situations and in other conflicts that may arise with career development. Additionally, the mentees felt that mentoring contributed to the development of leadership skills required for the job market and assist in personal development. This paper concludes that participation of young medical physicists in a mentoring group program is beneficial to their career and therefore should be encouraged.

Abstract
We report on a comparison between the theoretically predicted and experimentally measured spectra of the first-forbidden nonunique β-decay transition ^{137}Xe(7/2^{-})→^{137}Cs(7/2^{+}). The experimental data were acquired by the EXO-200 experiment during a deployment of an AmBe neutron source. The ultralow background environment of EXO-200, together with dedicated source deployment and analysis procedures, allowed for collection of a pure sample of the decays, with an estimated signal to background ratio of more than 99 to 1 in the energy range from 1075 to 4175 keV. In addition to providing a rare and accurate measurement of the first-forbidden nonunique β-decay shape, this work constitutes a novel test of the calculated electron spectral shapes in the context of the reactor antineutrino anomaly and spectral bump.

Abstract
OBJECTIVE To investigate the effect of miR-146a gene silencing on brain tissue and related drug-resistance proteins in rats and explore its resistance mechanism. MATERIALS AND METHODS A rat model of chronic refractory epilepsy was established. The rats were divided into four groups: Normal group, Model group, Negative control group and AntagomiR-146a group. Hematoxylin and eosin (HE) stain was used to detect brain histopathological changes. We examined the expression of mRNA of miR-146a, multidrug resistance (MDR1) and multidrug-resistant associated protein (MRP1) by RT-PCR. The expressions of protein of High motility group box 1 (HMGB1)/Toll-like receptor 4 (TLR4)/nuclear transcription factor-κB (NF-κB) pathway and P-glycoprotein (P-gp), MRP1 were detected by Western-blotting. RESULTS We demonstrated that the pathological lesion was lighter in antagomiR-146a group compared with the model group. The mRNA expression of miR-146a in AntagomiR-146a group was significantly decreased compared to the model group. Furthermore, the mRNA expression of MDR1 and MRP1 in AntagomiR-146a group was lower than that in the model group. In addition, the protein expression of HMGB1, TLR4, NF-κB and P-gp, MRP1 in AntagomiR-146a group was lower than that in model group. CONCLUSIONS These results demonstrated that miR-146a gene silencing can attenuate pathological changes and improve drug resistance in refractory epilepsy. Also, it is closely related to the HMGB1/TLR4/NF-κB signaling pathway regulation.

Abstract
A search for neutrinoless double-β decay (0νββ) in ^{136}Xe is performed with the full EXO-200 dataset using a deep neural network to discriminate between 0νββ and background events. Relative to previous analyses, the signal detection efficiency has been raised from 80.8% to 96.4±3.0%, and the energy resolution of the detector at the Q value of ^{136}Xe 0νββ has been improved from σ/E=1.23% to 1.15±0.02% with the upgraded detector. Accounting for the new data, the median 90% confidence level 0νββ half-life sensitivity for this analysis is 5.0×10^{25} yr with a total ^{136}Xe exposure of 234.1 kg yr. No statistically significant evidence for 0νββ is observed, leading to a lower limit on the 0νββ half-life of 3.5×10^{25} yr at the 90% confidence level.

Abstract
We report on the highest energy photons from the Crab Nebula observed by the Tibet air shower array with the underground water-Cherenkov-type muon detector array. Based on the criterion of a muon number measured in an air shower, we successfully suppress 99.92% of the cosmic-ray background events with energies E>100 TeV. As a result, we observed 24 photonlike events with E>100 TeV against 5.5 background events, which corresponds to a 5.6σ statistical significance. This is the first detection of photons with E>100 TeV from an astrophysical source.

Abstract
Objective: To investigate the correlation between interleukin-6 (IL-6) single nucleotide polymorphism (SNP) and the occurrence and prognosis of hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF). Methods: Patients with chronic hepatic diseases diagnosed as HBV infection in the Hepatology Center of the First Affiliated Hospital of Fujian Medical University from July 2012 to March 2018 were divided into HBV-ACLF and non-ACLF group. SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) was determined by the improved multi-temperature ligase detection reaction (imLDRTM) technique. Simultaneously, case data were reviewed with the 3-months followed up survival condition of the ACLF group. Normally distributed data were expressed as arithmetic means and SDs, and t-test was adopted. Data with skewed distribution were expressed as medians with interquartile range, and were measured by non-parametric test. Multivariate logistic regression analysis was used to analyze the relative risk of genetic polymorphism and HBV-ACLF as well as the relationship between IL-6 SNPs with the occurrence and prognosis of HBV-ACLF. Results: Four hundred patients were included in the study, with 122 (30.5%) in the HBV-ACLF and 278 (69.5%) in the non-ACLF group. There were significant differences in total bilirubin, albumin, and white blood cell count, percentage of neutrophils, platelet count, alanine aminotransferase, aspartate aminotransferase, prothrombin time and international standardized ratio, creatinine and the model for end-stage liver disease score between the two groups (P < 0.001). The genotype of IL-6 genes (rs1800795, rs1800797, rs2069827, and rs2069830) of all subjects showed no mutation or the mutation rate under 1%. There was no significant difference in the genotype of IL-6 (rs1524107, rs2069837, rs2069840 and rs2069845) between the two groups (P > 0.05). Multivariate logistic regression analysis showed that the SNPs in the above four loci of IL-6 gene was not associated with HBV-ACLF risk, nor had significant correlation with the 3-months prognosis. Conclusion: The SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) is unrelated to the occurrence and short-term prognosis of HBV-ACLF.

Abstract
Objective: To investigate the effect of the derepression of chemokine receptor-7 (CXCR7) in prostatic tissues from patients with Castration Resistant Prostate Cancer (CRPC) on the resistance to enzalutamide (Enza). Methods: During the period of January 2015 to December 2017 all CRPC cases who underwent radical radiotherapy or androgen deprivation therapy (ADT) were evaluated. After prostatic puncture biopsy, the tissues were treated for immunostaining with CXCR7. Cox proportional hazard modeling and Kaplan-Meier analysis were used to determine PSA Progression-Free Survival (PSAP-FS) and Clinical or Radiographic Progression-Free Survival (CRP-FS) in the cohort. At last, PSA response rates and progression outcomes in CXCR7 negative cases and CXCR7 positive cases were analyzed. Results: Total 39 CRPC patients were enrolled in this study. And 23 cases derepress CXCR7, 16 cases negatively express CXCR7. The median follow-up duration was 12 months (range: 6-18) in the cohort. Chi-square analysis confirmed that PSA response rates after Enza treatment were significantly associated with CXCR7 derepression (χ(2)=22.129, P=0.000 06). Compared with CXCR7 positive expression group, CXCR7 negative expression group displayed improved median PSAP-FS (4.4 mon vs 11.7 mon, P=0.040 8) and CRP-FS (5.2 mon vs 13.1 mon, P=0.036 2) after Enza treatment. Conclusion: Derepression of CXCR7 in CRPC patients may be associated with resistance to enzalutamide. This protein may be novel target for treatment of CRPC.

Abstract
BACKGROUND AND PURPOSE Spine debulking surgery in patients with hypervascular spinal metastasis is associated with massive intraoperative blood loss, but currently, the vascularity of tumor is determined by invasive conventional angiography or dynamic contrast MR imaging. We aimed to investigate the usefulness of noninvasive dual-energy CT-DSA, comparing it with conventional angiography in evaluating the vascularity of spinal metastasis. MATERIALS AND METHODS We conducted a retrospective study from January to December 2018. A total of 15 patients with spinal metastasis undergoing dual-energy CT, conventional DSA, and subsequent debulking surgery were included. CT-DSA images were produced after rigid-body registration and subtraction between CT phases. Qualitative and quantitative assessments of tumor vascularity were conducted. Correlations between CT-DSA and conventional DSA results were evaluated using the Spearman coefficient. The mean enhancement in the estimated tumor volume and surgical blood loss was compared between hypervascular and nonhypervascular groups using the Wilcoxon rank sum test. RESULTS The CT-DSA and DSA results were strongly correlated, with ρ = 0.87 (P < .001). The DSA and the quantitative enhancement index also showed a strong correlation with ρ = 0.83 (P < .001). Wilcoxon rank sum testing between hypervascular and nonhypervascular CT-DSA groups showed a difference in enhancement indices (P = .0003). The blood loss between the hypervascular and nonhypervascular groups was nonsignificant (P = .09). CONCLUSIONS Dual-energy CT-DSA correlates well with conventional DSA in assessing the vascularity of spinal metastasis. It may serve as a noninvasive preoperative evaluation option before debulking surgery.

Abstract
INTRODUCTION Airborne fine particulate matter (PM2.5; particulate matter ≤ 2.5 μm in aerodynamic diameter) plays a key role in air quality, climate, and public health. Globally, the largest mass fraction of PM2.5 is organic, dominated by secondary organic aerosol (SOA) formed from atmospheric oxidation of volatile organic compounds (VOCs). Isoprene from vegetation is the most abundant nonmethane VOC emitted into Earth's atmosphere. Isoprene has been recently recognized as one of the major sources of global SOA production that is enhanced by the presence of anthropogenic pollutants, such as acidic sulfate derived from sulfur dioxide (SO2), through multiphase chemistry of its oxidation products. Considering the abundance of isoprene-derived SOA in the atmosphere, understanding mechanisms of adverse health effects through inhalation exposure is critical to mitigating its potential impact on public health. Although previous studies have examined the toxicological effects of certain isoprene-derived gas-phase oxidation products, to date, no systematic studies have examined the potential toxicological effects of isoprene-derived SOA, its constituents, or its SOA precursors on human lung cells. SPECIFIC AIMS The overall objective of this study was to investigate the early biological effects of isoprene-derived SOA and its subtypes on BEAS-2B cells (a human bronchial epithelial cell line), with a particular focus on the alteration of oxidative stress- and inflammation-related genes. To achieve this objective, there were two specific aims. 1. Examine toxicity and early biological effects of SOA derived from the photochemical oxidation of isoprene, considering both urban and downwind-urban types of chemistry. 2. Examine toxicity and early biological effects of SOA derived directly from downstream oxidation products of isoprene (i.e., epoxides and hydroperoxides). METHODS Isoprene-derived SOA was first generated by photooxidation of isoprene under natural sunlight in the presence of nitric oxide (NO) and acidified sulfate aerosols. Experiments were conducted in a 120-m3 outdoor Teflon-film chamber located on the roof of the Gillings School of Global Public Health, University of North Carolina at Chapel Hill (UNC-Chapel Hill). BEAS-2B cells were exposed to chamber- generated isoprene-derived SOA using the Electrostatic Aerosol in Vitro Exposure System (EAVES). This approach allowed us to generate atmospherically relevant compositions of isoprene-derived SOA and to examine its toxicity through in vitro exposures at an air-liquid interface, providing a more biologically relevant exposure model. Isoprene-derived SOA samples were also collected, concurrently with EAVES sampling, onto Teflon membrane filters for in vitro resuspension exposures and for analysis of aerosol chemical composition by gas chromatography/electron ionization-quadrupole mass spectrometry (GC/EI-MS) with prior trimethylsilylation and ultra-performance liquid-chromatography coupled to high-resolution quadrupole time-of-flight mass spectrometry equipped with electrospray ionization (UPLC/ESI-HR-QTOFMS). Isoprene-derived SOA samples were also analyzed by the dithiothreitol (DTT) assay in order to characterize their reactive oxygen species (ROS)-generation potential. Organic synthesis of known isoprene-derived SOA precursors, which included isoprene epoxydiols (IEPOX), methacrylic acid epoxide (MAE), and isoprene-derived hydroxyhydroperoxides (ISOPOOH), was conducted in order to isolate major isoprene-derived SOA formation pathways from each other and to determine which of these pathways (or SOA types) is potentially more toxic. Since IEPOX and MAE produce SOA through multiphase chemistry onto acidic sulfate aerosol, dark reactive uptake experiments of IEPOX and MAE in the presence of acidic sulfate aerosol were performed in a 10-m3 flexible Teflon indoor chamber at UNC-Chapel Hill. Since the generation of SOA from ISOPOOH (through a non-IEPOX route) requires a hydroxyl radical (•OH)-initiated oxidation, ozonolysis of tetramethylethylene (TME) was used to form the needed •OH radicals in the indoor chamber. The resultant low-volatility multifunctional hydroperoxides condensed onto nonacidified sulfate aerosol, yielding the ISOPOOH-derived SOA needed for exposures. Similar to the outdoor chamber SOAs, IEPOX, MAE- and ISOPOOH-derived SOAs were collected onto Teflon membrane filters and were subsequently chemically characterized by GC/EI-MS and UPLC/ESI-HR-QTOFMS as well as for ROS-generation potential using the DTT assay. These filters were also used for resuspension in vitro exposures. By conducting gene expression profiling, we provided mechanistic insights into the potential health effects of isoprene-derived SOA. First, gene expression profiling of 84 oxidative stress- and 249 inflammation-associated human genes was performed for cells exposed to isoprene-derived SOA generated in our outdoor chamber experiments in EAVES or by resuspension. Two pathway-focused panels were utilized for this purpose: (1) nCounter GX Human Inflammation Kit comprised of 249 human genes (NanoString), and (2) Human Oxidative Stress Plus RT2 Profiler PCR Array (Qiagen) comprised of 84 oxidative stress-associated genes. We compared the gene expression levels in cells exposed to SOA generated in an outdoor chamber from photochemical oxidation of isoprene in the presence of NO and acidified sulfate seed aerosol to cells exposed to a dark control mixture of isoprene, NO, and acidified sulfate seed aerosol to isolate the effects of the isoprene-derived SOA on the cells using the EAVES and resuspension exposure methods. Pathway-based analysis was performed for significantly altered genes using the ConsensusPathDB database, which is a database system for the integration of human gene functional interactions to provide biological pathway information for a gene set of interest. Pathway annotation was performed to provide biological pathway information for each gene set. The gene-gene interaction networks were constructed and visualized using the GeneMANIA Cytoscape app (version 3.4.1) to predict the putative function of altered genes. Lastly, isoprene-derived SOA collected onto filters was used in resuspension exposures to measure select inflammatory biomarkers, including interleukin 8 (IL-8) and prostaglandin-endoperoxide synthase 2 (PTGS2) genes, in BEAS-2B cells to ensure that effects observed from EAVES exposures were attributable to particle-phase organic products. Since EAVES and resuspension exposures compared well, gene expression profiling for IEPOX-, MAE- and ISOPOOH-derived SOA were conducted using only resuspension exposures. RESULTS AND CONCLUSIONS Chemical characterization coupled with biological analyses show that atmospherically relevant compositions of isoprene-derived SOA alter the levels of 41 oxidative stress-related genes. Of the different composition types of isoprene-derived SOA, MAE- and ISOPOOH-derived SOA altered the greatest number of genes, suggesting that carbonyl and hydroperoxide functional groups are oxidative stress promoters. Taken together, the different composition types accounted for 34 of the genes altered by the total isoprene-derived SOA mixture, while 7 remained unique to the total mixture exposures, indicating that there is either a synergistic effect of the different isoprene-derived SOA components or an unaccounted component in the mixture. The high-oxides of nitrogen (NOx) regime, which yielded MAE- and methacrolein (MACR)-derived SOA, had a higher ROS-generation potential (as measured by the DTT assay) than the low- NOx regime, which included IEPOX- and isoprene-derived SOA. However, ISOPOOH-derived SOA, which also formed in the low- NOx regime, had the highest ROS-generation potential, similar to 1,4-naphthoquinone (1,4-NQ). This suggests that aerosol-phase organic peroxides contribute significantly to particulate matter (PM) oxidative potential. MAE- and MACR- derived SOA showed equal or greater ROS-generation potential than was reported in prior UNC-Chapel Hill studies on diesel exhaust PM, highlighting the importance of a comprehensive investigation of the toxicity of isoprene-derived SOA. Notably, ISOPOOH-derived SOA was one order of magnitude higher in ROS-generation potential than diesel exhaust particles previously examined at UNC-Chapel Hill. As an acellular assay, the DTT assay may not be predictive of oxidative stress; therefore, we also focused on the gene expression results from the cellular exposures. We have demonstrated that the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and the redox-sensitive activation protein-1 (AP-1) transcription factor networks have been significantly altered upon exposure to isoprene-derived SOA. The identification of Nrf2 pathway in cells exposed to isoprene-derived SOA is in accordance with our findings using the DTT assay, which measures the thiol reactivity of PM samples as a surrogate for their ROS-generation potential. Specifically, our results point to the cysteine-thiol modifications within cells that lead to activation of Nrf2-related gene expression. However, based on our gene expression results showing no clear relationship between DTT activity and the number of altered oxidative stress-related genes, the DTT activity of isoprene-derived SOA may not be directly indicative of toxicity relative to other SOA types. While activation of Nrf2-associated genes has been identified with responses to oxidative stress and linked to traffic related air pollution exposure in both toxicological and epidemiological studies, their implicit involvement in this study suggests that activation of Nrf2-related gene expression may occur with exposures to all sorts of PM types. By controlling the exposure time, method, and dose we demonstrated that among the SOA derived from previously identified individual precursors of isoprene-derived SOA, ISOPOOH-derived SOA alters more oxidative stress related genes than does IEPOX-derived SOA, but fewer than MAE-derived SOA. This suggests that the composition of MAE-derived SOA may be the greatest contributor to alterations of oxidative stress-related gene expression observed due to isoprene-derived SOA exposure. Further study on induced levels of protein expression and specific toxicological endpoints is necessary to determine if the observed gene expression changes lead to adverse health effects. In addition, such studies have implications for pollution-control strategies because NOx and SO2 are controllable pollutants that can alter the composition of SOA, and in turn alter its effects on gene expression. The mass fraction of different components of atmospheric isoprene derived SOA should be considered, but altering the fraction of high- NOx isoprene-derived SOA (e.g., MAE derived SOA) may yield greater changes in gene expression than altering the fraction of low- NOx isoprene derived SOA types (ISOPOOH- or IEPOX-derived SOA). Finally, this study confirms that total isoprene-derived SOA alters the expression of a greater number of genes than does SOA derived from the tested precursors. This warrants further work to determine the underlying explanation for this observation, which may be uncharacterized components of isoprene-derived SOA or the potential for synergism between the studied components.

Abstract
BACKGROUND AND PURPOSE Simple-but-precise evaluation of cerebral perfusion is crucial for the treatment of Moyamoya disease. We aimed to develop a standardized scoring system for MR perfusion suitable for Moyamoya disease evaluation and investigate the postoperative serial changes and outcome predictors. MATERIALS AND METHODS From January 2013 to December 2016, patients diagnosed with Moyamoya disease and receiving indirect revascularization were recruited prospectively. Clinical data and serial imaging studies were analyzed. The TTP maps were standardized using cerebellar reference values. We developed a scoring system of standardized TTP maps: 14 points for each hemisphere with higher points indicating better perfusion. RESULTS In total, 24 children (4-17 years of age, 41 hemispheres) and 20 adults (18-51 years of age, 34 hemispheres) were included. The mean preoperative TTP scores were higher in children (7.34 ± 3.90) than in adults (4.88 ± 3.24). The standardized TTP maps revealed dynamic improvement with an increase in the corresponding scores at the 1-, 3-, and 6-month postoperative follow-ups; the scores stabilized after 6 months. The mean improvement in the 6-month scores of the pediatric and adult groups was 4.15 ± 3.55 and 6.03 ± 3.04, respectively. The 6-month TTP score improvements were associated with Matsushima grades. If we took score improvement as the outcome, the preoperative TTP score was the only significant predictor in multivariable analysis. CONCLUSIONS The standardized TTP maps and scoring system facilitated the quantification of the sequential perfusion changes during Moyamoya disease treatment. The preoperative perfusion status was the only predictor of indirect revascularization outcome.

Abstract
Objective: To investigate the role of hypoxia-inducible factor-1α (HIF-1α) and β-catenin in radioresistance of prostate cancer (PCa) cells. Method: Two PCa cell lines, LNCaP and C4-2B, were grouped as: negative control (no treatment), HIF-1α overexpression group (transfected with HIF-1α plasmids), and β-catenin silencing group (transfected with HIF-1α plasmids and β-catenin-shRNA). Cell proliferation, cycle, invasion, and radiosensitivity were measured under normal or hypoxic condition. Radiosensitivity was tested in two mice PCa models (the LNCaP orthotopic BALB/c-nu mice model and the C4-2B subcutaneous SCID mice model). Results: In both LNCaP and C4-2B cells, HIF-1α transfection led to an enhanced β-catenin nuclear translocation, while β-catenin silencing inhibited the β-catenin nuclear translocation. Enhanced β-catenin nuclear translocation caused by HIF-1α overexpression resulted in enhanced cell proliferation and invasion, altered cell cycle distribution, reduced apoptosis, and improved non-homologous-end-joining (NHEJ) repair under irradiation condition. In vivo imaging of orthotopic models showed that HIF-1α overexpression LNCaP cells produced tumors with 3-fold volume (P=0.003 1) and 2-fold wet weight (P=0.039 4) than those by negative control cells at day 21, and β-catenin silencing cells aberrantly reduced both tumor volume (P=0.000 3) and wet weight (P=0.017 5) than HIF-1α overexpression cells. In addition, C4-2B subcutaneous models showed similar tumor promotion effects induced by HIF-1α overexpression (tumor volume: P=0.000 1 and wet weight: P=0.047 3) and suppressive effects by β-catenin silencing (tumor volume: P<0.000 1 and wet weight: P=0.022 1) as LNCaP orthotopic xenograft with regard to tumor volume and wet weight. Conclusions: HIF-1α overexpression enhanced β-catenin nuclear translocation, which led to the activation of the β-catenin/NHEJ signaling pathway and increased cell proliferation, invasion, and DNA repair. These results suggest that HIF-1α overexpression led to radioresistance of PCa cells.

Abstract
BACKGROUND AND PURPOSE Permanent common carotid artery and/or ICA occlusion is an effective treatment for carotid blowout syndrome. Besides postoperative thromboembolic infarction, permanent common carotid artery and/or ICA occlusion may cause borderzone infarction when the collateral flow to the deprived brain territory is inadequate. In this study, we aimed to test the predictive value of CTA for post-permanent common carotid artery and/or ICA occlusion borderzone infarction in patients with carotid blowout syndrome. MATERIALS AND METHODS In this retrospective study, we included 31 patients undergoing unilateral permanent common carotid artery and/or ICA occlusion for carotid blowout syndrome between May 2009 and December 2016. The vascular diameter of the circle of Willis was evaluated using preprocedural CTA, and the risk of borderzone infarction was graded as very high risk, high risk, intermediate risk, low risk, and very low risk. RESULTS The performance of readers' consensus on CTA for predicting borderzone infarction was excellent, with an area under receiver operating characteristic curve of 0.938 (95% confidence interval, 0.85-1.00). We defined very high risk, high risk, and intermediate risk as positive for borderzone infarction, the sensitivity, specificity, positive predictive value, and negative predictive value of CTA for borderzone infarction were 100% (7/7), 62.5% (15/24), 43.8% (7/16), and 100% (15/15), respectively. The interobserver reliability was excellent (κ = 0.807). No significant difference in the receiver operating characteristic curves was found between the 2 readers (P = .114). CONCLUSIONS CTA can be used to predict borderzone infarction after permanent common carotid artery and/or ICA occlusion by measuring the collateral vessels of the circle of Willis.

Abstract
Objective: To explore the relationship between smoking and hyperuricemia in Chinese residents. Methods: Based on data from the China Health and Nutrition Survey (CHNS), residents with blood samples provided in the 2009 round (including information of socio-demographic factors, lifestyle behaviors, medical history, and laboratory examinations etc.) were selected as the participants in the current analysis. Unconditional logistic regression models were utilized to compute the ORs and corresponding 95%CIs for assessing the relationship between smoking and hyperuricemia. Results: Among the 8 785 subjects, 1 435 had hyperuricemia with a prevalence rate of 16.3%, consisting of 886 men and 549 women with prevalence rates of 21.6% (886/4 110) and 11.7% (549/4 675) , respectively. Compared with never smokers, the adjusted OR (95%CI) for hyperuricemia was 0.83 (0.70-0.98) among current smokers, 0.77 (0.63-0.94) among current smokers with 20-39 years of smoking, and 0.79 (0.65-0.97) among current smokers with 11-20 cigarettes per day. When stratified by gender and compared with non-smoker, the adjusted OR (95%CI) for hyperuricemia among current smokers compared with never smokers was 0.83 (0.70-0.98) among men, while no significant association was found in female current smokers (OR=0.73, 95%CI: 0.42-1.26, P=0.260). Conclusion: In Chinese residents, there is an inverse association between smoking and hyperuricemia prevalence, and this association may be related to duration and intensity of smoking among current smokers. The findings need to be validated in large prospective cohort studies.

Abstract
BACKGROUND Bacterial Infection is the most important source of mortality and morbidity in liver transplantation recipients. Donor transmitted bacterial infection is rare but one of the most important infection sources. This kind of infection is difficult to identify, causing treatment dilemma. PATIENTS AND METHODS In this article, we retrospectively reviewed our deceased donor liver transplants performed from January 2014 to December 2016. Forty-two recipients in Kaohsiung Chang Gung Memorial Hospital receiving liver grafts from 35 deceased liver donors were evaluated. The demography, donor transmitted infection, and outcomes were evaluated. RESULT Two patients had probable donor transmitted bacterial infection and 1 patient died of suspected transmitted infection. CONCLUSION Early identification of donor infection and adequate antibiotic treatment for the donor and recipient are the keys to preventing donor transmitted bacterial infection. Donor infection is not an absolute contraindication for organ donation in the area of organ shortage. Organ procurement organizations or similar authorities may establish the platform for sharing the data about donor and recipient infections.

Abstract
Objective: To investigate the oncologic outcome and PSA kinetics of localized high-risk prostate cancer (PCa) patients treated with combination strategy of radiation therapy (RT) and maximal androgen blockade (MAB). Methods: We retrospectively reviewed the clinical data of 320 localized PCa patients undergoing RT+ MAB from 2001 to 2015. And radiation treatment protocol consisted of permanent prostate brachytherapy (PPB) at 110 Gy and EBRT at 45 Gy/23 fractions. Results: The median follow-up time was 90 (range: 12-186) months. And 117 (36.6%) cases underwent MAB + external-beam radiotherapy (EBRT), and other 203 (63.4%) cases received MAB+ EBRT+ PPB. Multivariate Cox regression analyses showed that PSA kinetics were positive indicators of oncologic outcomes. Furthermore, PSA kinetics were aberrantly improved by supplemental PPB to MAB+ EBRT as following, PSA nadir (1.3±0.7)μg/L vs(0.11±0.06)μg/L, time of PSA decrease to nadir (7.5±1.8)months vs (3.2±2.1)months, PSA doubling time (15.6±4.2)months vs (22.6±6.1)months, PSA decreasing amplitude (84.6±6.2)%vs(95.8±3.4)%. Additionally, the median time of several important oncologic events in MAB+ EBRT+ PPB group were also prolonged than that in MAB+ EBRT group as following, overall survival (12.3 years vs 9.1 years, P<0.001), biochemical recurrence-free survival (9.8 years vs 6.5 years, P<0.001), skeletal-related event (10.4years vs 8.2 years, P<0.001), and cytotoxic chemotherapy (11.6 years vs 8.8 years, P=0.007). Conclusion: MAB+ EBRT+ PPB is extremely effective combination strategy for localized high-risk PCa patients, and PPB plays the important synergistic role in improving PSA kinetics, which are independent predictor for oncologic outcomes.

Abstract
BACKGROUND Liver stiffness is associated with the degree of fibrosis along with other factors. Abrupt change of liver perfusion after hepatectomy is one such factor. In this study, we performed ultrasound elastography to explore the stiffness of the right lobe liver before and after hepatectomy in donors who underwent resection of left lobe or lateral segment of liver. METHODS A total of 32 left lobe liver donors (18 male and 14 female; age range, 21-55 years; mean age, 35.1 years; 19 left lobectomy with middle hepatic reserved for graft and 13 lateral segmentectomy with middle hepatic vein reserved in the remnant liver) were included in this study. Liver stiffness was measured by means of ultrasound elastography with the use of acoustic radiation force impulse imaging. Stiffness of the right lobe liver was obtained by means of right intercostal approach. RESULTS The stiffness of remnant right lobe liver significantly increased after hepatectomy (1.24 ± 0.18 vs 1.10 ± 0.13 m/s; P = .001). Donors of left lobe liver showed higher stiffness in the remnant right lobe liver compared with donors of lateral segment (1.30 ± 0.18 vs 1.15 ± 0.14 m/s; P = .027). There was no significant correlation between the remnant right lobe liver stiffness, postoperative liver function, and flow parameters of hepatic artery and portal vein. CONCLUSIONS The stiffness of remnant liver significantly increased after hepatectomy. Furthermore, the stiffness was higher in donors undergoing left lobectomy compared with those undergoing lateral segmentectomy.

Abstract
OBJECTIVES Vancomycin-intermediate Staphylococcus aureus (VISA) is associated with genetic changes that may also impact upon pathogenicity. In the current study, we compared the virulence of clinical VISA strains with their isogenic vancomycin-susceptible progenitors (VSSA). METHODS Production of the critical virulence protein, α toxin, was assessed using Western blot analysis and was correlated to agr activity using a bioluminescent agr-reporter. Cytotoxicity and intracellular persistence were compared ex vivo for VSSA and VISA within non-professional phagocytes (NPP). Virulence and host immune responses were further explored in vivo using a murine model of bacteraemia. RESULTS VISA isolates produced up to 20-fold less α toxin compared with VSSA, and this was corroborated by either loss of agr activity due to agr mutation, or altered agr activity in the absence of mutation. VISA were less cytotoxic towards NPP and were associated with enhanced intracellular persistence, suggesting that NPP may act as a reservoir for VISA. Infection with VSSA strains produced higher mortality in a murine bacteraemia model (≥90% 7-day mortality) compared with infection with VISA isolates (20% to 50%, p <0.001). Mice infected with VISA produced a dampened immune response (4.6-fold reduction in interleukin-6, p <0.001) and persistent organ bacterial growth was observed for VISA strains out to 7 days. CONCLUSIONS These findings highlight the remarkable adaptability of S. aureus, whereby, in addition to having reduced antibiotic susceptibility, VISA alter the expression of pathogenic factors to circumvent the host immune response to favour persistent infection over acute virulence.

Abstract
In order to evaluate the milk yield, milk quality, and health of dairy cows fed a high-concentrate (HC) diet, eight lactating Holstein dairy cattle were randomly assigned to HC or low-concentrate (LC) diet groups and fed for 50 days, and the auto-control studying before and after treatment with the two diets was used. During the experiment, plasma and milk samples were collected and measured. With regard to milk component, HC feeding led to higher milk production (P < 0.05), but significantly lower milk protein percentage (P < 0.05), milk protein yield (P < 0.05), and milk fat percentage (P < 0.05) throughout the five periods than LC feeding. Milk somatic cell count and N-acetyl-D-glucosaminidase activity (P < 0.01) were higher than those observed under LC feeding. mRNA expression levels of interleukin-8 (IL-8), C-C motif chemokine ligand (CCL5), and lactalbumin alpha (α-LA) were investigated by qPCR and found to be significantly lower (P < 0.01) in cattle fed the HC diet. The amino acid content was analyzed by high performance liquid chromatography (HPLC), and the content of Asp (P < 0.01), Gln (P < 0.01), Ala (P < 0.05), Leu (P < 0.05), Lys (P < 0.05), and Ile (P < 0.01) was significantly lower in the HC group, whereas the content of Arg (P < 0.05) and Phe (P < 0.01) was significantly higher. These results suggest that the HC diet might have an important influence on mammary health. The amino acid content was lower, suggesting that depletion of amino acids, resulting in depleted milk protein, affects milk quality.

Abstract
In vertebrates, evolutionarily conserved signaling intermediate in the Toll pathway (ECSIT) interacts with the TNF-receptor associated factor 6 (TRAF6) to regulate the processing of MEKK1, activate NF-κB, and also control BMP target genes. However, the role of ECSIT in invertebrates remains largely unexplored. We performed comparative investigations of the expression, gene structure, and phylogeny of ECSIT, Toll-like receptor (TLR), and Smad4 in the cephalochordate Branchiostoma belcheri. Phylogenetic analysis indicated that, in amphioxus, ECSIT, TLR, and Smad4 form independent clusters at the base of Chordate clusters. Interestingly, overall gene structures were comparable to those in vertebrate orthologs. Transcripts of AmphiECSIT were detectable at the mid-neural stage, and continued to be expressed in the epithelium of the pharyngeal region at later stages. In adult animals, strong expression was observed in the nerve cord, endostyle, epithelial cells of the gut and wheel organ, genital membrane of the testis, and coelom and lymphoid cavities, what is highly similar to AmphiTLR and AmphiSmad4 expression patterns during development and in adult organisms. Our data suggests that ECSIT is evolutionarily conserved. Its amphioxus ortholog functions during embryonic development and as part of the innate immune system and may be involved in TLR/BMP signaling.

Abstract
Global smartphone penetration has led to unprecedented addictive behaviors. To develop a smartphone use/non-use pattern by mobile application (App) in order to identify problematic smartphone use, a total of 79 college students were monitored by the App for 1 month. The App-generated parameters included the daily use/non-use frequency, the total duration and the daily median of the duration per epoch. We introduced two other parameters, the root mean square of the successive differences (RMSSD) and the Similarity Index, in order to explore the similarity in use and non-use between participants. The non-use frequency, non-use duration and non-use-median parameters were able to significantly predict problematic smartphone use. A lower value for the RMSSD and Similarity Index, which represent a higher use/non-use similarity, were also associated with the problematic smartphone use. The use/non-use similarity is able to predict problematic smartphone use and reach beyond just determining whether a person shows excessive use.

Abstract
BACKGROUND Chest computed tomography (CT) as a primary screening method in candidates for living donor liver transplantation (LDLT) is not yet a standardized procedure. The aim of this study is to present our methods and result of evaluation of pulmonary small nodules (PSN) after CT as a primary screening tool. PATIENTS AND METHODS A total of 360 primary adult LDLTs were performed between October 2009 and December 2012. The 37 candidates with PSNs found on CT were divided into two groups, with 23 patients in the group that was chest radiography (CXR) positive (+) and 14 in the group that was CXR negative (-). RESULTS The nodular size in the CXR (-) group was significantly smaller than in the CXR (+) group (3.86 ± 1.24 vs 7.56 ± 4.08, P = .004). The sensitivity of CT for PSN was 37/360 (10.28%), much higher than the 14/360 (3.89%) for CXR alone. A total of 27 patients underwent video-assisted thoracoscopic surgery for pathologic diagnosis, and 10 were diagnosed as having benign PSNs by stationary sizes on serial CT scans. In the CXR (-) group, there were 2 cases of malignancy, 3 tuberculosis (TB), 3 Cryptococcus, and 15 other benign PS. In the CXR (+) group, there were 1 malignancy, 3 TB, 4 Cryptococcus, and other 6 benign PSNs. Recurrent infection was not seen in the posttransplantation follow-up of 13 candidates with infections. Excluding the 3 malignant PSNs, the 34 candidates in both groups survived 100% for more than 2 years after LDLT. CONCLUSION To exclude malignancy and to diagnose infectious PSN for further treatment in a timely manner, chest CT should be used as the primary screening tool for asymptomatic candidates for LDLT.

Abstract
Fate and function of anchorage-dependent cells depend on a variety of environmental cues, including those of mechanical nature. Previous progress in the understanding of cellular mechanosensitivity has been closely linked to the availability of artificial cell substrates of adjustable viscoelasticity, allowing for a direct correlation between substrate stiffness and cell response. Exemplary, polymeric gel substrates with polymer-conjugated cell-substrate linkers provided valuable insight into the role of mechanical signals during cell migration in an extracellular matrix environment. In contrast, less is known about the role of external mechanical signals across cell-cell interfaces, in part, due to the limitations of traditional polymeric substrates to mimic the remarkable dynamics of cell-cell linkages. To overcome this shortcoming, we introduce a cell surface-mimicking cell substrate of adjustable stiffness, which is comprised of a polymer-tethered lipid multi-bilayer stack with N-cadherin linkers. Unlike traditional polymeric cell substrates with polymer-conjugated linkers, this novel artificial cell substrate is able to replicate the dynamic assembly/disassembly of cadherin linkers into linker clusters and the long-range movements of cadherin-based cell-substrate linkages observed at cell-cell interfaces. Moreover, substrate stiffness can be changed by adjusting the number of bilayers in the multi-bilayer stack, thus enabling the analysis of cellular mechanosensitivity in the presence of artificial cell-cell linkages. The presented biomembrane-mimicking cell substrate provides a valuable tool to explore the functional role of mechanical cues from neighboring cells.

Abstract
Endothelial progenitor cells (EPCs) are bone marrow-derived endothelial cells capable of circulating, proliferating, and differentiating into mature endothelial cells. Circulating EPCs can be directly recruited to some extent at sites of injury, and their administration could accelerate repair or endothelialization of the damaged tissue. We investigated the effects of intracavernous injections of EPCs into the corpora cavernosa of rats with erectile dysfunction (ED) caused by bilateral cavernous nerve (CN) injury. Overall, 24 male Sprague-Dawley rats were randomized into three groups: sham surgery, vehicle-only, or EPC treatment. Rats in the EPC treatment and vehicle-only groups were subjected to bilateral CN injury before injection of EPCs or vehicle, respectively, into the corpora cavernosa. Four weeks after surgery, erectile function was assessed by measuring maximum intracavernosal pressure (ICP), change in ICP, area under the ICP curve, and ratio of change in ICP and mean arterial pressure (MAP; ΔICP/MAP). Penile tissue was histomorphometrically analyzed for the expression of neural nitric oxide synthase (nNOS), neurofilament-1 (NF-1), von Willebrand factor (vWF), endothelial NOS (eNOS), and smooth muscle cell content. Maximum ICP and all other functional parameters of erectile function were significantly reduced in the vehicle-only group vs. the sham and EPC treatment groups (all p < 0.001). Smooth muscle cell content was decreased in the vehicle-only vs. the sham and EPC treatment groups (both p < 0.01). Expressions of vWF and eNOS in the dorsal artery were significantly higher in the EPC treatment than the vehicle-only group (p < 0.05). In conclusion, EPC treatment restored erectile function in a rat model of bilateral CN injury through recruitment of EPCs toward the dorsal artery and preservation of smooth muscle cells in the corpus cavernosum. These findings elucidate the therapeutic potential of EPCs for treating ED in humans.
