Abstract
Objective: To describe the clinical characteristics of patients with non-small cell lung cancer (NSCLC) who developed checkpoint inhibitor pneumonitis (CIP) and to explore potential prognostic factors. Methods: NSCLC patients who were complicated with CIP after immune checkpoint inhibitors (ICIs) therapy in our institute were enrolled in this study from 1 July 2018 to 30 November 2022. Clinical data of NSCLC-CIP patients were collected, including clinical and radiological features and their outcomes. Results: Among the 70 enrolled NSCLC-CIP patients, there were 57 males (81%) and 13 females (19%). The mean age at the diagnosis of CIP was (65.2±6.3) years. There were 46 smokers (66%), 26 patients (37%) with emphysema, 19 patients (27%) with previous interstitial lung disease, and 26 patients (37%) with a history of thoracic radiation. The mean interval from the first application of checkpoint inhibitor to the onset of CIP was (122.7±106.9) days (range: 2-458 days). The main chest CT manifestations were coincided with non-specific interstitial pneumonia (NSIP) pattern and organizing pneumonia (OP) pattern. Most patients had grade 2 (21 cases) or grade 3 (34 cases) CIP. Seventeen patients had been concurrent with other immune-related adverse events such as rash, hepatitis, colitis, and thyroiditis. Half of the enrolled patients (36 patients/51%) had fever, and most patients had elevated C-reactive protein (52 patients/72%) and all patients had elevated erythrocyte sedimentation rate (70 patients/100%). Serum lactate dehydrogenase was elevated in 34 CIP patients. Prednisone≥1 mg·kg-1·d-1 (or equivalent) was the most commonly used initial treatment in CIP patients (50 patients/71.4%). Complications with pulmonary infections (OR=4.44, P=0.03), use of anti-fungal drugs (OR=5.10, P=0.03) or therapeutic dose of sulfamethoxazole (OR=4.86, P=0.04), longer duration of prednisone≥1 mg·kg-1·d-1 (or equivalent) (Z=-2.33, P=0.02) were probable potential risk factors for poor prognosis. Conclusions: Older males with smoking history might be predisposed to develop NSCLC-CIPs after ICIs therapy. NSIP pattern and OP pattern were common chest CT manifestations. Complications with pulmonary infections (especially fungal infection or Pneumocystis jirovecii pneumonia), longer duration, longer duration of high-dose corticosteroids were likely potential risk factors for poor prognosis.

Abstract
PURPOSE This study aimed to establish a nomogram to predict the risk of venous thromboembolism (VTE), identifying potential risk factors, and providing theoretical basis for prevention of VTE after spinal surgery. METHODS A retrospective analysis was conducted on 2754 patients who underwent spinal surgery. The general characteristics of the training group were initially screened using univariate logistic analysis, and the LASSO method was used for optimal prediction. Subsequently, multivariate logistic regression analysis was performed to identify independent risk factors for postoperative VTE in the training group, and a nomogram for predict risk of VTE was established. The discrimination, calibration, and clinical usefulness of the nomogram were separately evaluated using the C-index, receiver operating characteristic curve, calibration plot and clinical decision curve, and was validated using data from the validation group finally. RESULTS Multivariate logistic regression analysis identified 10 independent risk factors for VTE after spinal surgery. A nomogram was established based on these independent risk factors. The C-index for the training and validation groups indicating high accuracy and stability of the model. The area under the receiver operating characteristic curve indicating excellent discrimination ability; the calibration curves showed outstanding calibration for both the training and validation groups. Decision curve analysis showed the clinical net benefit of using the nomogram could be maximized in the probability threshold range of 0.01-1. CONCLUSION Patients undergoing spinal surgery with elevated D-dimer levels, prolonger surgical, and cervical surgery have higher risk of VTE. The nomogram can provide a theoretical basis for clinicians to prevent VTE.

Abstract
Objective: To describe the clinical characteristics of SARS-CoV-2 infected patients with interstitial lung abnormalities (ILA) during the COVID-19 pandemic. Methods: We respectively enrolled ILA patients who had been regularly followed up in Peking Union Medical College Hospital for more than six months since January 2021. Clinical data of these ILA patients were collected after the outbreak of COVID-19 pandemic (from December 2022 to January 2023), thirty-eight patients with preexisting ILA were enrolled. Among them, there were 34 ILA patients (20 males and 14 females) who were infected with SARS-CoV-2 during this period, with an average age of (64.0±8.8) years old (range: 41-80). There were 12 (35.3%) ILA patients who were suffered from COVID-19(pneumonia group) and others were the non-pneumonia group. The clinical characteristics, including vaccination status, features of COVID-19 and outcomes of the two groups were compared. Results: Regarding the subcategories of ILA, there were 7 cases of subpleural fibrotic ILA, 10 cases of subpleural non-fibrotic ILA, and 17 cases of non-subpleural ILA. Before SARS-CoV-2 infection, the average pulse oxygen saturation at rest was (97.38±0.87)% (range: 96%-99%); average forced vital capacity (FVC) was (97.6±18.1)% predicted (range: 65%-132%); and average diffusion capacity for carbon monoxide (DLCO) was (76.2±16.3)% predicted (range: 53%-108%). Nineteen patients had been vaccinated with 3 doses of SARS-CoV-2 vaccines, and 5 of them developed COVID-19. One patient had received one dose of vaccine and did not develop COVID-19. The other 14 patients had not been vaccinated, and seven of them developed COVID-19. Of the 12 patients with COVID-19, six were diagnosed with severe COVID-19, and the other 6 ILA patients were diagnosed with moderate COVID-19. Among them, 1 patient was complicated by deep vein thrombosis of left lower limb. All 6 patients with severe COVID-19 who were cured after systemic corticosteroids. As for the other six moderate COVID-19 patients, all were cured and/or improved greatly: two were treated with short-term oral corticosteroids, one was prescribed a dose of compound betamethasone, and the other two were not treated with systemic corticosteroids. Conclusion: Patients with ILA were predisposed to develop COVID-19 after infection with SARS-CoV-2, and more than half of them had severe COVID-19.

Abstract
Oncogenic KRAS mutations were identified decades ago, yet the selective inhibition of specific KRAS mutant proteins represents an ongoing challenge. Recent progress has been made in targeting certain P-loop mutant proteins, in particular KRAS G12C, for which the covalent inhibition of the GDP state via the Switch II pocket is now a clinically validated strategy. Inhibition of other KRAS mutant proteins such as KRAS G13D, on the other hand, still requires clinical validation. The remoteness of the D13 residue relative to the Switch II pocket in combination with the solvent exposure and conformational flexibility of the D13 side chain, as well as the difficulties of targeting carboxylate residues covalently, renders this specific protein particularly challenging to target selectively. In this report, we describe the design and evaluation of potent and KRAS G13D-selective reversible inhibitors. Subnanomolar binding to the GDP state Switch II pocket and biochemical selectivity over WT KRAS are achieved by leveraging a salt bridge with D13.

Abstract
Adipose-derived mesenchymal stem cell-derived small extracellular vesicles (Ad-MSC-sEVs/AMEs) combined with scaffold materials are used in tissue-engineered bladders; however, the lack of retention leads to limited distribution of AMEs in the scaffold areas and low bioavailability of AMEs after bladder reconstruction. To improve retention of AMEs, we developed a novel strategy that modifies the surface charge of the bladder acellular matrix (BAM) via oxidative self-polymerization of dopamine-reducing graphene oxide (GO) and AMEs using ε-polylysine-polyethylene-distearyl phosphatidylethanolamine (PPD). We evaluated two BAM surface modification methods and evaluated the biocompatibility of materials and PPD and electrostatic adherence effects between PPD-modified AMEs and rGO-PDA/BAM in vivo and in vitro. Surface modification increased retention of AMEs, enhanced regeneration of bladder structures, and increased electrical conductivity of rGO-PDA/BAM, thereby improving bladder function recovery. RNA-sequencing revealed 543 miRNAs in human AMEs and 514 miRNAs in rat AMEs. A Venn diagram was used to show target genes of miRNA with the highest proportion predicted by the four databases; related biological processes and pathways were predicted by KEGG and GO analyses. We report a strategy for improving bioavailability of AMEs for bladder reconstruction and reveal that enriched miR-21-5p targets PIK3R1 and activates the PI3K/Akt pathway to promote cell proliferation and migration.

Abstract
AIM To explore and compare the ultrasonic (US) features of pilomatricoma (PM) and epidermoid cyst (EC) in the differential diagnosis and improve the accuracy of US diagnosis of PM. MATERIALS AND METHODS Three hundred and nine patients who underwent US examination before surgery with a histopathological diagnosis of PM or EC after surgery were analysed retrospectively. The patients were categorised into the training and validation sets according to the inspection times. Univariate analysis was undertaken on the US and clinical features of PM and statistically significant variables (p<0.05) were included in the multivariate logistic regression model to establish a diagnostic model. RESULTS The results demonstrated that the multivariate logistic regression model for PM was statistically significant (p<0.001). The risk factors included posterior echo attenuation and hypoechoic halos (odds ratio [OR] = 9.277, 10.254) and the protective factors included age, diameter thickness, and posterior echo enhancement (OR=0.936, 0.302, 0.156). The performance of the diagnostic model was tested using the training set (area under the receiver operating characteristic curve [AUC] = 0.974, 95% confidence interval [CI] = 0.955-0.994) and the validation set (AUC = 0.967, 95% CI = 0.926-1.000), which demonstrated good discriminant ability. CONCLUSIONS The diagnostic accuracy for PM was higher than that for EC when the nodule is characterised by posterior echo attenuation, hypoechoic halos, smaller thickness, and younger age. The US diagnostic model developed may be used to guide the diagnosis of PM.

Abstract
Background Successful treatment of infectious bone defect remains a major challenge in the orthopaedic field. At present, the conventional treatment for infectious bone defects is surgical debridement and long-term systemic antibiotic use. It is necessary to develop a new strategy to achieve effective bone regeneration and local anti-infection for infectious bone defects. Methods Firstly, vancomycin / poly (lactic acid-glycolic acid) sustained release microspheres (VAN/PLGA-MS) were prepared. Then, through the dual-nozzle 3D printing technology, VAN/PLGA-MS was uniformly loaded into the pores of nano-hydroxyapatite (n-HA) and polylactic acid (PLA) scaffolds printed in a certain proportion, and a composite scaffold (VAN/MS-PLA/n-HA) was designed, which can not only promote bone repair but also resist local infection. Finally, the performance of the composite scaffold was evaluated by in vivo and in vitro biological evaluation. Results The in vitro release test of microspheres showed that the release of VAN/PLGA-MS was relatively stable from the second day, and the average daily release concentration was about 15.75 μg/mL, which was higher than the minimum concentration specified in the guidelines. The bacteriostatic test in vitro showed that VAN/PLGA-MS had obvious inhibitory effect on Staphylococcus aureus ATCC-29213. Biological evaluation of VAN/MS-PLA/n-HA scaffolds in vitro showed that it can promote the proliferation of adipose stem cells. In vivo biological evaluation showed that VAN/MS-PLA/n-HA scaffold could significantly promote bone regeneration. Conclusion Our research shows that VAN/MS-PLA/n-HA scaffolds have satisfying biomechanical properties, effectively inhibit the growth of Staphylococcus aureus, with good biocompatibility, and effectiveness on repairing bone defects. The VAN/MS-PLA/n-HA scaffold provide the clinic with an application prospect in bone tissue engineering.

Abstract
Objective: To describe the clinical characteristics and prognosis of lung cancer concomitant with interstitial lung disease (LC-ILD), and to understand the current status of knowledge of LC-ILD by physicians in the departments related to the treatment of the disease. Methods: We conducted a retrospective analysis of in-hospitalized pathology identified lung cancer (LC) patients who were admitted to our hospital between January 2014 and December 2018. After reviewing their chest CT imagings and pathological reports, 70 patients who were concomitant with interstitial lung disease (ILD) were enrolled in our study. On the other hand, a cross-sectional survey using an online questionnaire was conducted in LC-ILD management doctors who came from 29 provincial hospitals. The perceptions of demographic features, LC characteristics and management, ILD characteristics and management, and the prognosis of LC-ILD were investigated. Results: Among the 70 enrolled LC-ILD cases, there were 52 males, and the mean age was (64.3±7.63) years (ranged from 49 years to 84 years). There were 51 patients who were older than 59 years. The most common pathological pattern of LC was adenocarcinoma. Most of them were diagnosed with LC and ILD simultaneously, and they were usually treated with chemotherapy while unresectable. There were 11 patients (15.7%) with positive EGFR or ALK mutation. Forty-five patients (64.3%) died during the follow-up, and 33 were died from LC progression. There were no significant differences between the surgical group and non-surgical group on age, pathological patterns, EGFR or ALK mutation. However, LC-ILD patients in the surgical group were diagnosed with earlier TNM classification and with better prognosis. A total of 1 014 doctors answered the questionnaire completely. In the feedback, patients aged 60 years and older (785 doctors/77.4%), and male patients (720 doctors/71%) were the predominant LC-ILD patients. Adenocarcinoma (390 doctors/38.5%), adenocarcinoma or squamous-cell cancer (SCC) (182 doctors/17.9%), and SCC (151 doctors/14.9%) were considered as the common pathological patterns of LC-ILD patients. In most doctors' feedback, the EGFR or ALK mutation was not common for LC-ILD: low (646 doctors/63.7%) or hardly (306 doctors/30.5%) positive mutation. The diagnosis of ILD was earlier than LC (506 doctors/49.9%) or there was no identified precedence of LC and ILD diagnosis (208 doctors/20.5%). Most of the doctors (693 doctors/68.3%) agreed that the vital factor for surgery or not was the severity of ILD for LC-ILD patients. There were great divergences on the treatment protocol both for the advanced LC and ILD. The patients with LC-ILD were died mostly from LC progression and ILD exacerbation (542 doctors/53.5%), followed by ILD exacerbation (237 doctors/23.4%) or LC progression (226 doctors/22.3%). Conclusions: The elderly male patients were predisposed to LC-ILD, and adenocarcinoma was the common pathological pattern. The LC-ILD patients with non-advanced LC who were performed with surgery had better prognosis. However, it is recommended to consider whether to perform surgery in combination with the severity of the ILD.

Abstract
Nanocellulose is regarded as a green and renewable nanomaterial that has attracted increased attention. In this study, we demonstrate that nanocellulose materials can exhibit high thermal conductivity when their nanofibrils are highly aligned and bonded in the form of filaments. The thermal conductivity of individual filaments, consisting of highly aligned cellulose nanofibrils, fabricated by the flow-focusing method is measured in dried condition using a T-type measurement technique. The maximum thermal conductivity of the nanocellulose filaments obtained is 14.5 W/m-K, which is approximately five times higher than those of cellulose nanopaper and cellulose nanocrystals. Structural investigations suggest that the crystallinity of the filament remarkably influence their thermal conductivity. Smaller diameter filaments with higher crystallinity, that is, more internanofibril hydrogen bonds and less intrananofibril disorder, tend to have higher thermal conductivity. Temperature-dependence measurements also reveal that the filaments exhibit phonon transport at effective dimension between 2D and 3D.

Abstract
Objectives: To describe the underlying diseases, microbiologic examination and severity of hospitalized patients with Pneumocystis jirovecii pneumonia (PJP) in a tertiary Chinese hospital. Methods: We conducted a retrospective analysis of 485 identified PJP patients who were admitted to our hospital between January 2013 and December 2021. Results: Among the 485 enrolled PJP cases, there were 237 males and 248 females, aging (53.3±16.2) years (range from 14 y to 88 y). They were divided into 8 subgroups with variable underlying diseases. There were 209 cases with connective tissue diseases(CTD), 27 cases with non-hematologic malignancies, 38 cases with hematologic malignancies, 81 cases with kidney diseases, 33 cases with idiopathic interstitial pneumonia(IIP), 30 cases infected with human immunodeficiency virus (HIV), and 42 cases with miscellaneous underlying diseases. In the CTD group, there was more females than males, while male patients were predominant in both the malignant and the HIV groups. The Pneumocystis was identified in 44.95%(218/485) sputum samples and 92.01%(265/288) bronchoscopic samples. Pneumocystis asci were observed at direct microscopic examination with Grocott's methenamine silver stain in 4.95%(24/485)sputum samples and 9.72%(28/288)bronchoscopic samples. Pneumocystis DNA fragments were identified by PCR analysis in 43.09%(209/485)sputum samples and 90.63%(261/288)bronchoscopic samples. Among the 8 groups, cytomegaviremia and respiratory failure were most common in the HIV-infected PJP group, but the rates of mechanic ventilation, intensive care unit (ICU) admission and death were the lowest. There were less PJP patients in the IIP group (IIP-PJP) who received mechanic ventilation and admitted to ICU than the other groups except HIV-infected PJP group. However, the mortality rate was highest for the IIP-PJP group. Conclusions: CTD was the most common predisposed underlying disease for our enrolled PJP cases. Cytomegaviremia and respiratory failure were common in HIV-infected PJP patients, but the prognosis of HIV-PJP was slightly better than the others. The disease was more severe, rapidly progressive and fatal in the IIP-PJP group.

Abstract
Objectives: To describe the clinical characteristics of patients with autoimmune diseases associated interstitial lung diseases (AID-ILD) initially presented with idiopathic pulmonary fibrosis (IPF) in a tertiary Chinese hospital. Methods: We conducted a retrospective analysis of 14 patients diagnosed with AID-ILD during the IPF follow-up between January 2016 and December 2021. Among the 14 enrolled AID-ILD cases, there were 13 males and 1 female, (69.71±9.07) years old (range from 55 y to 87 y). Results: Detailed clinical consultation and further laboratory analysis were performed during the follow-up when the IPF patients showed exaggerated dyspnea (7 cases), fever of unknown causes (6 cases), microscopic hematuria (5 cases), arthralgia and swelling (4 cases), arthralgia (2 cases), morning stiffness (2 cases) and renal failure (2 cases). Finally, 6 patients showed positive MPO-ANCA, one patient showed positive PR3-ANCA and 7 patients showed positive anti-CCP. During the IPF periods, 7 patients had received antifibrotic agents and 5 patients had been prescribed with N-acetylcysteine, and 1 patient had received antifibrotic agents after N-acetylcysteine. Among them, no medication was prescribed for one IPF patient. After they were diagnosed with AID-ILD, glucocorticoids and/or immunosuppressants were added for 13 of them. Thirteen of cases improved or stable after these treatments, but one didn't show significant changes. Conclusions: AID-UIP, especially ANCA-UIP, AAV-UIP or RA-UIP should be considered when the IPF patients showed fever of unknown origin, microscopic hematuria and/or arthritis related symptoms. They might benefit from the add-on glucocorticoids and/or immunosuppressants.

Abstract
Background Spinal epidural abscess (SEA) is an uncommon clinical entity that is often subject to delayed diagnosis and suboptimal treatment. Untreated disease leads to compression of the spinal cord, resulting in devastating complications. Case Presentation A 56‐year‐old man visited our hospital for progressive lower back and lower extremity pain of several days' duration. Significant pyrexia (39.5°C) and elevated C‐reactive protein (89.2 mg/L) were detected during admission, but no positive neurological examination findings were observed. Magnetic resonance imaging revealed pyogenic discitis at L3–4. Despite the administration of directed antibiotic therapy, the patient's condition rapidly deteriorated, culminating in complete paraplegia secondary to an extensive SEA from L4 to C7. Emergency spinal decompression surgery was canceled due to his poor clinical condition and refusal of informed consent. After further deterioration, he consented to two‐level selective laminectomies and irrigation. Conclusions In contrast with prior case reports, this case illustrates the natural history of an extensive SEA during conservative and late surgical treatment. Early diagnosis and timely surgical decompression are of great importance for extensive SEA.

Abstract
Objective: Our study aims to determine histological regression and clinical improvement after long-term antiviral therapy in hepatitis B virus-related cirrhosis patients. Methods: Treatment-naïve chronic hepatitis B patients with histologically or clinically diagnosed liver cirrhosis were enrolled. Liver biopsies were performed after 5 years entecavir-based antiviral treatment. Patients were followed up every 6 months. Cirrhosis regression was evaluated based on Metavir system and P-I-R score. Clinical improvement was evaluated before and after the long-term treatment. Kruskal Wallis test and Wilcoxon signed-rank test were used for continuous variables, Fisher's exact test was used for categorical variables and multivariate analysis was performed using logistic regression analysis. Results: Totals of 73 patients with HBV-related liver cirrhosis were enrolled. Among them, 30 (41.1%) patients were biopsy proved liver cirrhosis and the remaining 43 (58.9%) cirrhotic patients were diagnosed by clinical features. Based on Metavir system and P-I-R score, 72.6% (53/73) patients attained histological regression. Furthermore, 30.1% (22/73) were defined as significant regression (Metavir decrease ≥2 stage), 42.5% (31/73) were mild regression (Metavir decrease 1 stage or predominantly regressive by P-I-R system if still cirrhosis after treatment) and 27.4% (20/73) were the non-regression. Compared to levels of clinical characteristics at baseline, HBV DNA, ALT, AST, liver stiffness(decreased from 12.7 to 6.4 kPa in significant regression, from 18.1 to 7.3 kPa in mild regression and from 21.4 to 11.2 kPa in non-regression)and Ishak-HAI score significantly decreased after 5 years of anti-HBV treatment, while serum levels of platelets and albumin improved remarkably (P<0.05). In multivariate analysis, only the pre-treatment liver stiffness level was associated with significant regression (OR=0.887, 95%CI: 0.802-0.981, P=0.020). Conclusions: After long-term antiviral therapy, patients with HBV-related cirrhosis are easily to attain improvements in clinical parameters, while a certain percentage of these patients still cannot achieve histological reversal.

Abstract
The electrical transport properties of typical hexagonal metals are anisotropic because of their anisotropic lattice structures. Unexpectedly, we show that the electron transport properties in hexagonal close-packed (hcp) noble metals are almost isotropic. Although the electron transport properties of an individual electronic band are highly anisotropic, the total contributions are almost equal in different crystalline orientations because of the complementary contributions of different bands. The electron transport is severely limited by phonons for metals with multisheet Fermi surfaces and optical phonon polarizations. However, it is found the electron-phonon interactions are weak in hcp noble metals, although their Fermi surfaces and phonon spectra are complicated. The electronic structure acts as a phonon filter, resulting in small electron-phonon scattering rates. The weak electron-phonon interactions are beneficial to electron and thermal transport, indicating hcp noble metals have great potential to be used in electronics and solar cells.

Abstract
Ultrafast water permeation in aquaporins is promoted by their hydrophobic interior surface. Polytetrafluoroethylene has a dense fluorine surface, leading to its strong water repellence. We report a series of fluorous oligoamide nanorings with interior diameters ranging from 0.9 to 1.9 nanometers. These nanorings undergo supramolecular polymerization in phospholipid bilayer membranes to form fluorous nanochannels, the interior walls of which are densely covered with fluorine atoms. The nanochannel with the smallest diameter exhibits a water permeation flux that is two orders of magnitude greater than those of aquaporins and carbon nanotubes. The proposed nanochannel exhibits negligible chloride ion (Cl-) permeability caused by a powerful electrostatic barrier provided by the electrostatically negative fluorous interior surface. Thus, this nanochannel is expected to show nearly perfect salt reflectance for desalination.

Abstract
Methacryloyloxydecyl dihydrogen phosphate (MDP) has been speculated to induce mineralization, but there has been no convincing evidence of its ability to induce intrafibrillar mineralization. Polymers play a critical role in biomimetic mineralization as stabilizers/inducers of amorphous precursors. Hence, MDP-induced biomimetic mineralization without polymer additives has not been fully verified or elucidated. By combining 3-dimensional stochastic optical reconstruction microscopy, surface zeta potentials, contact angle measurements, inductively coupled plasma-optical emission spectroscopy, transmission electron microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy with circular dichroism, we show that amphiphilic MDP can not only demineralize dentin by releasing protons as an acidic functional monomer but also infiltrate collagen fibrils (including dentin collagen), unwind the triple helical structure by breaking hydrogen bonds, and finally immobilize within collagen. MDP-bound collagen functions as a huge collagenous phosphoprotein (HCPP), in contrast to chemical phosphorylation modifications. HCPP can induce biomimetic mineralization itself without polymer additives by alternatively attracting calcium and phosphate through electrostatic attraction. Therefore, we herein propose the dual functions of amphiphilic MDP monomer with de- and remineralizing ability. MDP in the free state can demineralize dentin substrates by releasing protons, whereas MDP in the collagen-bound state as HCPP can induce intrafibrillar mineralization. The dual functions of MDP monomer with de- and remineralization properties might create a new epoch in adhesive dentistry and preventive dentistry.

Abstract
Objective: To describe the clinical characteristics of sarcoidosis patients with arrhythmia as the primary or main manifestation. Methods: We conducted a retrospective analysis of arrhythmia-onset sarcoidosis cases between January 2017 and December 2020. Their clinical manifestations, radiological features, treatment and prognosis were reviewed and analyzed. Results: This study consisted of 3 females and 1 male, with a mean age of 51 years (range from 42 to 58 years old). Arrhythmia was the first or main clinical manifestation for all 4 cases, involving Ⅲ° atrioventricular block (AVB) (n=1), Ⅱ° type Ⅱ AVB (n=1), and frequent ventricular premature beats and short array ventricular tachycardia (n=2). Three cases were diagnosed with respiratory sarcoidosis simultaneously during the diagnostic evaluation for arrhythmia. One case was diagnosed with sarcoidosis because of abnormal chest CT images due to cervical lymph node enlargement 5 years after arrhythmia. All 4 cases were confirmed as presenting epithelioid cell granulomatous inflammation by bronchoscopic biopsies. Late gadolinium enhancement with cardiac magnetic resonance (LGE-CMR) imaging was arranged for two cases. Both of them had typical imaging findings of cardiac sarcoidosis. Three cases were confirmed of cardiac involvement through positron emission computed tomography (PET)-CT. None of the enrolled four cases were arranged with endomyocardial biopsy. All four cases were improved with oral corticosteroids, immunosuppressants and anti-arrhythmic medications. Two cases underwent cardiac pacemaker implantation. Conclusions: The possibility of cardiac sarcoidosis should be considered in middle-aged and elderly patients with unexplained high-degree AVB or ventricular arrhythmia. Chest CT is recommended for routine screening for those cases. LGE-CMR and/or PET-CT is recommended for them to confirm the diagnosis of cardiac sarcoidosis. Corticosteroids and immunosuppressants are effective for these patients.

Abstract
Objective To evaluate the placement feasibility and safety of the newly designed retropharyngeal reduction plate by cadaveric test and to perform morphometric trajectory analysis. Methods The five cadaveric specimens with intact atlantoaxial joint were enrolled in this study. They were used for simulating the placement process and evaluating the placement feasibility of the retropharyngeal reduction plate. The atlantoaxial dislocation (AAD) of five cadaveric specimens were obtained by proper external force after dissecting ligaments. The retropharyngeal reduction plate was placed on atlantoaxial joint of cadaveric specimens. The X‐ray and three‐dimensional (3D) spiral CT were used for evaluating the placement safety of retropharyngeal reduction plate. The DICOM data was obtained after 3D spiral CT scanning for the morphometric trajectory analysis. Results The reduction plates were successfully placed on the atlantoaxial joint of five cadaveric specimens through the retropharyngeal approach, respectively. The X‐ray and 3D spiral CT showed the accurate screw implantation and satisfying plate placement. The length of the left/right atlas screw trajectory (L/RAT) was, respectively, 1.73 ± 0.01 cm (LAT) and 1.71 ± 0.02 cm (RAT). The length of odontoid screw trajectory (OST) was 1.38 ± 0.02 cm. The length of the left/right axis screw trajectory (L/RAXT) was, respectively, 1.67 ± 0.02 cm (LAXT) and 1.67 ± 0.01 cm (RAXT). There was no statistical significance between left side and right side in terms of AT and AXT (P > 0.05). The angles of atlas screw trajectory angle (ASTA), axis screw trajectory angle (AXSTA), and odontoid screw trajectory angle (OSTA) were 38.04° ± 2.03°, 56.92° ± 2.66°, and 34.78° ± 2.87°, respectively. Conclusion The cadaveric test showed that the retropharyngeal reduction plate is feasible to place on the atlantoaxial joint, which is also a safe treatment choice for atlantoaxial dislocation. The meticulous preoperative planning of screw trajectory based on individual differences was also vital to using this technique.

Abstract
Global warming results in high temperature stress (HTS), which presents severe challenges worldwide for modern agricultural production and will have significant impacts on the yield and quality of crops. Accumulation of photosynthetic products, activity of enzymes involved in sucrose-starch metabolism, phytohormone levels and metabolic profiling using LC-MS were analysed in the flag leaves and/or developing grains subjected to HTS during the grain-filling stage of an indica rice. HTS induced significant yield loss and reduced the grain quality, with lower amylose content. HTS reduced photosynthetic product accumulation in flag leaves and reduced starch accumulation in developing grains, compared to growth under normal temperatures. The activity of enzymes related to sucrose-starch metabolism were dis-regulated in developing grains grown under high temperature (HT). Moreover, phytohormone homeostasis in flag leaves and developing grains was also dramatically disturbed by HT. Metabolic profiling detected many metabolites with remarkably different relative fold abundances at different time points in the developing grain at HT versus normal temperatures, these metabolites were enriched in several HTS response pathways. The change in phytohormone ratio and auxin level might be associated with the reduction in photosynthetic products and their translocation, and ultimately with reduced starch accumulation in the developing grain. The detected metabolites might have different roles in response to the HTS in developing grain at different development stages. These results provide a theoretical reference and basis for future rice production towards higher quality and yield when grown under HTS.

Abstract
We identify two distinct regimes for the diffusion of the ionic liquid [BMIM][PF6] confined between parallel graphene walls using molecular dynamics simulations. Within 2 nm of the wall, the cations and anions form a well-defined layered structure. In this region, the in-plane diffusion coefficients are suppressed when compared to their bulk values and increase monotonically with the distance away from the wall. Beyond 2 nm from the wall, the density profile and in-plane diffusion coefficients recover their bulk values. The channel-averaged in-plane diffusion coefficients increase monotonically with wall separation and recover the bulk values at a separation of 15 nm. A simple semianalytical model is proposed that mirrors this trend. The results also highlight the importance of applying a finite-size correction to molecular dynamics-predicted diffusion coefficients of confined liquids, which may otherwise be unusually larger than their bulk values.

Abstract
Thermal boundary conductance is typically positively correlated with interfacial adhesion at the interface. Here, we demonstrate a counterintuitive experimental result in which a weak van der Waals interface can give a higher thermal boundary conductance than a strong covalently bonded interface. This occurs in a system with highly mismatched vibrational frequencies (copper/diamond) modified by a self-assembled monolayer. Using finely controlled fabrication and detailed characterization, complemented by molecular simulation, the effects of bridging the vibrational spectrum mismatch and bonding at the interface are systematically varied and understood from a molecular dynamics viewpoint. The results reveal that the bridging and binding effects have a trade-off relationship and, consequently, that the bridging can overwhelm the binding effect at a highly mismatched interface. This study provides a comprehensive understanding of phonon transport at interfaces, unifying physical and chemical understandings, and allowing interfacial tailoring of the thermal transport in various material systems.

Abstract
AIM To investigate the efficacy of the maximum signal intensity of tumour on T1-weighted magnetic resonance imaging (MRI) images for differentiating Warthin's tumours (WTs) from pleomorphic adenomas (PAs) and malignant tumours (MTs). MATERIALS AND METHODS One hundred and fifty-four histopathologically confirmed parotid tumours, including 76 PAs, 45 WTs, and 33 MTs, were analysed. MRI results were compared with pathological findings. The maximum signal intensity of tumour and the average signal intensity of spinal cord were measured on T1-weighted images, then the tumour-to-spinal cord signal intensity ratio (T1-max-SIR) was calculated. The distribution of T1-max-SIRs among the three groups of tumours was analysed using the Mann-Whitney U-test. Receiver operating characteristic curves were generated to assess the ability of T1-max-SIRs to differentiate parotid tumours. In addition, the interobserver agreement between readers was assessed using interclass correlation coefficient (ICC). RESULTS T1-max-SIRs were higher in WTs than in PAs (p<0.001) and MTs (p<0.001), and no significant difference was found between PAs and MTs (p=0.151). The area under the curve (AUC) of T1-max-SIRs for differentiating WTs from PAs was 0.901, with a sensitivity of 91.1% and a specificity of 82.9%. The AUC of T1-max-SIRs for differentiating WTs from MTs was 0.851, with a sensitivity of 88.9% and a specificity of 78.8%. Readers had excellent interobserver agreement on T1-max-SIRs (ICC = 0.989; 95% confidence interval, 0.985-0.992). CONCLUSIONS T1-max-SIRs can be useful for differentiating WTs from PAs and MTs with high diagnostic efficiency.

Abstract
BACKGROUND Autophagy-related genes (ARGs) have been confirmed to have an important role in tumorigenesis and tumor microenvironment formation. Nevertheless, a systematic analysis of ARGs and their clinical significance in sarcoma patients is lacking. METHODS Gene expression files from The Cancer Genome Atlas (TCGA) database and Genotype-Tissue Expression (GTEx) were used to select differentially expressed genes (DEGs). Differentially expressed ARGs (DEARGs) were determined by matching the DEG and HADb gene sets, which were evaluated by functional enrichment analysis. Unsupervised clustering of the identified DEARGs was conducted, and associations with tumor microenvironment (TME), immune checkpoints, and immune cells were analyzed simultaneously. Two prognostic signatures, one for overall survival (OS) and one for disease-free survival (DFS), were established and validated in an independent set. RESULTS In total, 84 DEARGs and two clusters were identified. TME scores, five immune checkpoints, and several types of immune cells were found to be significantly different between two clusters. Two prognostic signatures incorporating DEARGs showed favorable discrimination and were successfully validated. Two nomograms combining signature and clinical variables were generated. The C-indexes were 0.818 and 0.747 for the OS and DFS nomograms, respectively. CONCLUSION This comprehensive analyses of the ARG landscape in sarcoma showed novel ARGs related to carcinogenesis and the immune microenvironment. These findings have implications for prognosis and therapeutic responses, which reveal novel potential prognostic biomarkers, promote precision medicine, and provide potential novel targets for immunotherapy.

Abstract
Iron is one of the essential trace elements in the human body. An increasing amount of evidence indicates that the imbalance of iron metabolism is related to the occurrence and development of cancer. Here, we obtained the gene expression and clinical data of sarcoma patients from TCGA and the GEO database. The prognostic value of iron metabolism-related genes (IMRGs) in patients with sarcoma and the relationship between these genes and the immune microenvironment were studied by comprehensive bioinformatics analyses. Two signatures based on IMRGs were generated for the overall survival (OS) and disease-free survival (DFS) of sarcoma patients. At 3, 5, and 7 years, the areas under the curve (AUCs) of the OS signature were 0.708, 0.713, and 0.688, respectively. The AUCs of the DFS signature at 3, 5, and 7 years were 0.717, 0.689, and 0.702, respectively. Kaplan–Meier survival analysis indicated that the prognosis of high-risk patients was worse than that of low-risk patients. In addition, immunological analysis showed that there were different patterns of immune cell infiltration among patients in different clusters. Finally, we constructed two nomograms that can be used to predict the OS and DFS of sarcoma patients. The C-index was 0.766 (95% CI: 0.697–0.835) and 0.763 (95% CI: 0.706–0.820) for the OS and DFS nomograms, respectively. Both the ROC curves and the calibration plots showed that the two nomograms have good predictive performance. In summary, we constructed two IMRG-based prognostic models that can effectively predict the OS and DFS of sarcoma patients.

Abstract
The article is focused on capturing process-related dust at industrial enterprises (in chemical, metallurgical and energy industries). An electrocyclone can be recommended for the purification of gases emitted into the atmosphere from particulates, such as sodium percarbonate (efficiency 97.5%–99.9%), iron-vanadium concentrate (98.0% - 99.9%), fly ash (99.0%–99.9%). However, the fumes from copper-smelting furnaces cannot be purified with high efficiency (less than 50–60%) because of their properties. Using electrocyclone will reduce the amount of aerosol emissions, and in some cases, let the emission reach the values set by standards.

Abstract
Abstract
Introduction/Objective
We report a 68-year-old man with Human immunodeficiency virus (HIV) infection and significant weight loss during the past two years who presented with dyspnea. He was not receiving any treatment for HIV infection, and his viral load and CD4 count were 178000 copies/ml and 8 cells/mm3, respectively. The radiologic examination was concerning for Pneumocystis jirovecii pneumonia. The Bronchoalveolar lavage was positive for Pneumocystis jirovecii. The patient expired despite the comprehensive treatment, and the autopsy was requested.
Methods
The autopsy showed heavy lungs with diffuse consolidation and white discoloration involving all lobes. The left ventricular wall and right kidney cortex showed foci of white discoloration measuring 1 and 0.8 cm, respectively.
Results
The microscopic examination of lungs showed concurrent CMV pneumonia, and PCP confirmed by immunohistochemical staining for CMV and GMS special stain. The histologic evaluation of the heart and the right kidney and immunohistochemical staining for CD20 and CD3 in addition to in situ hybridization (ISH) for EBER revealed infiltrative malignant cells, which were positive for CD20 and EBER and negative for CD3. The EBV associated B-cell lymphoma involving the heart, and the right kidney was diagnosed
Conclusion
EBV is involved in human lymphomagenesis, particularly in HIV patients. There is a tendency for the lymphoma to involve the extranodal sites, including the CNS, gastrointestinal tract, liver, and bone marrow. However, the involvement of the heart and kidneys occurs very rarely. The autopsy findings of Lung co-infection with PCP and CMV and EBV associated lymphoma involving atypical locations is a rare and unique combination of AIDS-defining illnesses in this patient.

Abstract
OBJECTIVE To assess the effect of omega-3 polyunsaturated fatty acids (n-3 PUFA) on liver regeneration of rats with liver cirrhosis after hepatectomy and antifibrosis. MATERIALS AND METHODS Omega-3 polyunsaturated fatty acids were intravenously injected in n-3 PUFA group 3 days before the operation to 1 day after partial hepatectomy. 70% hepatectomy was performed in rats, which were subsequently divided into 4 groups, namely normal and hepatectomy group (PH); liver cirrhosis and hepatectomy group (LC+PH); liver cirrhosis, n-3 PUFA (1 mL/kg), and hepatectomy group (LC+n-3 PUFA+PH); liver cirrhosis, n-3 PUFA (2 mL/kg) and hepatectomy group (LC+n-3PUFA*+PH). Body/liver weight ratios, serum parameters, histopathological examination, immunostaining, inflammatory cytokine and quantification of mRNA expression were also investigated. RESULTS Liver regeneration was significantly delayed compared with PH group 7 days after hepatectomy (PH) in LC+PH group. Besides, liver regeneration of LC+n-3 PUFA*+PH group increased significantly compared with LC+PH group 7 days after PH. In LC+PH group, liver cirrhotic was significantly higher compared with LC+n-3 PUFA+PH group 7 days after PH. In the meantime, liver cirrhosis of LC+n-3 PUFA*+PH group was significantly reduced compared with LC+n-3 PUFA+PH group 7 days after PH. Anti-inflammatory cytokine IL-10 was increased and pro-inflammatory cytokine IL-6 was decreased in LC+n-3 PUFA*+PH group compared with LC+PH group. N-3 PUFA also suppressed increments in mRNA expression for transforming growth factor-β and up-regulated the expression of matrix metalloproteinase-9 and matrix metalloproteinase-1 in the liver. CONCLUSIONS The mentioned results clearly show that n-3 PUFA reduces liver fibrosis and promotes liver regeneration, even under cirrhotic conditions. This could be a potentially useful treatment for liver cirrhosis.

Abstract
Objectives: To describe the clinical features and prognosis of pulmonary actinomycosis in a tertiary Chinese hospital. Methods: We conducted a retrospective analysis of 32 patients diagnosed with pulmonary actinomycosis between January 2013 and December 2019. General characteristics, clinical manifestations, lab data, chest CT imaging, treatment and follow-up information were reviewed and analyzed. Results: This study consisted of 19 males and 13 females, with a mean age of (58±12) years, ranging from 16 to 76 years. There were 26 cases with co-morbidities. Among them, there were 16 cases with pulmonary co-morbidity. Sixteen cases had a smoking history. Eight cases, 5 men and 3 women, with a mean age of (48±8) years, ranging from 41 to 58 years, received thoracic surgery for diagnosis. The remaining 24 cases who did not receive thoracic surgery consisted of 14 males and 8 females, with a mean age of (54±14)years, ranging from 16 to 76 years. Cough (25cases), expectoration (21 cases) and fever (16 cases) were the common clinical manifestations. The erythrocyte sedimentation rate (ESR) ranged from 2 to 114 mm/1 h, with a mean value of (28±31) mm/1 h. The ESR was elevated (>20 mm/1 h) in 15 cases. The C-reactive protein (CRP) ranged from 1 to 116 mg/L, with a mean value of (28±45) mg/L. The CRP was elevated (>8 mg/L) in 16 cases. Localized air-space consolidation (18 cases), pulmonary mass or nodules (16 cases) were the common chest CT manifestations. When compared with non-surgical cases, fever was the sole characteristic that was less common in cases with thoracic surgery (1 case in surgical group vs 11 cases in non-surgical group, P<0.05). Actinomyces spp. was found in 7 cases (87.5%) who received thoracic surgery, in 16 (61.5%) specimens collected through bronchoscopy and in 10 (55.6%) sputum samples of good quality. All of our enrolled cases were administrated with oral antibiotics, and 14 cases were prescribed with intravenous antibiotics initially. Among them, 27 cases were administrated with more than one antibiotic. Penicillin, ampicillin and amoxillin were prescribed for 25 cases. Finally, 30 cases showed improvement or cure in our hospital. Conclusions: Pulmonary actinomycosis tended to develop in aged patients with co-morbidities. Cough, expectoration, fever and localized air-space consolidation were the common clinical and radiological manifestations, respectively. Actinomyces spp. could be found more easily in the surgically resected tissues than other specimens. The prognosis of our enrolled cases was good after treatment with combined antibiotics.

Abstract
1.The objective of the experiment was to analyse serum profiles of goslings with visceral gout and compare them with those of healthy individuals to identify differentially-abundant metabolites as potential biomarkers. 2.Untargeted gas chromatography and time-of-flight mass spectrometry (GC-TOF-MS) metabolomic profiling was used to compare the serum metabolome of 15 goslings (Anser cygnoides) with gout and 15 healthy goslings (control). 3.Goslings with gout had a metabolic profile distinct from that of the controls, with 45 metabolite levels differing significantly (VIP > 1; P < 0.05) between both groups. Nine metabolites (hydrocortisone, glucose, trans-4-hydroxy-L-proline, galactose, 2-deoxy-D-galactose, beta-mannosylglycerate, d-glucoheptose, zymosterol, and hypoxanthine) were selected through receiver operating characteristics (ROC) analysis (area under curve (AUC) score ≥0.85) as potential biomarkers. Pathway analysis revealed that metabolites with differing levels were mainly involved in galactose, arginine and proline and purine metabolisms. 4.These results provided new insights into the pathogenesis of gout. Increased xanthine and hypoxanthine with decreased hydrocortisone provide promising biomarkers for gosling gout diagnosis. The findings suggested that hepatic metabolic disorders frequently occur in the development of avian gout.

Abstract
Objective: To investigate whether CD137 signaling can promote angiogenesis via regulating macrophage M1/M2 polarization. Methods: (1) The primary peritoneal macrophages in mice induced by 3% thiglycollate broth were divided into three groups: control group, CD137 signaling activated group and CD137 signaling inhibited group. Various specific markers of M1 and M2 macrophages were detected to observe the phenotype change of macrophages, and the macrophages protein expression of CD137, CD86 and CD206 was detected by flow cytometry (FCM). The protein and mRNA expression of induced nitric oxide synthase (iNOS), arginase Ⅰ(Arg-1) was determined by Western blot and RT-PCR, respectively. The secretion levels of IL-12 and IL-10 in culture supernatant of macrophages were detected by ELISA. (2) Macrophages were co-cultured with the endothelial cells (bEnd.3), and macrophages were implanted in the upper chamber, endothelial cells were implanted in stromal glue of the lower chamber. The experiment was divided into three groups: the control group, CD137 signaling activated group and peroxisome proliferator-activated receptor-γ (PPAR-γ) inhibited group, and tube formation ability of endothelial cells in each group was determined. Results: (1) The purity of primary peritoneal macrophages in mice was (97.93±1.31)%. The expression of CD137 on the surface of macrophages was (97.40±2.70)%. (2) Compared with control group, the mRNA and protein expression levels of Arg-1 were significantly increased and the mRNA and protein expression of iNOS were significantly decreased in CD137 signaling activated group (all P<0.05). Compared with CD137 signaling activated group, the mRNA and protein expression of Arg-1 were significantly lower and the mRNA and protein expression levels of iNOS were significantly higher in CD137 signaling inhibited group (all P<0.05). FCM results showed that the average fluorescence intensity of CD206 was higher, while the average fluorescence intensity of CD86 was lower in CD137 signaling activated group than in control group (P<0.05, P<0.01, respectively); the expression of CD206 was significantly lower, while the expression of CD86 was higher, in the CD137 signaling inhibited group than in CD137 signaling activated group (P<0.05, P<0.01, respectively). ELISA results showed that the secretion of IL-10 was higher, and the secretion level of IL-12 was significantly lower in CD137 signaling activated group than in control group (both P<0.01); the secretion of IL-10 was significantly lower and the secretion of IL-12 was significantly higher in CD137 signaling inhibited group than in CD137 signaling activated group (both P<0.05). (3) Values of the formation of tube length and branch number were both longer in CD137 signaling activated group than control group (P<0.05). The formation of the tube length and branch number were less in PPAR-γ inhibited group than in CD137 signaling activated group (P<0.05). Conclusion: CD137 signaling can promote angiogenesis by regulating macrophage M1/M2 polarization.

Abstract
Background The efficient and accurate diagnosis of pulmonary adenocarcinoma before surgery is of considerable significance to clinicians. Although computed tomography (CT) examinations are widely used in practice, it is still challenging and time-consuming for radiologists to distinguish between different types of subcentimeter pulmonary nodules. Although there have been many deep learning algorithms proposed, their performance largely depends on vast amounts of data, which is difficult to collect in the medical imaging area. Therefore, we propose an automatic classification system for subcentimeter pulmonary adenocarcinoma, combining a convolutional neural network (CNN) and a generative adversarial network (GAN) to optimize clinical decision-making and to provide small dataset algorithm design ideas. Methods A total of 206 nodules with postoperative pathological labels were analyzed. Among them were 30 adenocarcinomas in situ (AISs), 119 minimally invasive adenocarcinomas (MIAs), and 57 invasive adenocarcinomas (IACs). Our system consisted of two parts, a GAN-based image synthesis, and a CNN classification. First, several popular existing GAN techniques were employed to augment the datasets, and comprehensive experiments were conducted to evaluate the quality of the GAN synthesis. Additionally, our classification system processes were based on two-dimensional (2D) nodule-centered CT patches without the need of manual labeling information. Results For GAN-based image synthesis, the visual Turing test showed that even radiologists could not tell the GAN-synthesized from the raw images (accuracy: primary radiologist 56%, senior radiologist 65%). For CNN classification, our progressive growing wGAN improved the performance of CNN most effectively (area under the curve =0.83). The experiments indicated that the proposed GAN augmentation method improved the classification accuracy by 23.5% (from 37.0% to 60.5%) and 7.3% (from 53.2% to 60.5%) in comparison with training methods using raw and common augmented images respectively. The performance of this combined GAN and CNN method (accuracy: 60.5%±2.6%) was comparable to the state-of-the-art methods, and our CNN was also more lightweight. Conclusions The experiments revealed that GAN synthesis techniques could effectively alleviate the problem of insufficient data in medical imaging. The proposed GAN plus CNN framework can be generalized for use in building other computer-aided detection (CADx) algorithms and thus assist in diagnosis.

Abstract
Background Atlantoaxial subluxation (AAS) is a not rare abnormality between the atlas (C1) and axis (C2). For AAS patients with persistent neck pain and neurologic symptoms, surgical intervention is a good choice. Nevertheless, there were still few reports about the use of intraoperative skull traction and different fixation methods in treatment of AAS. Methods From January 2012 to December 2018, a total of 86 cases were admitted to our hospital and diagnosed as AAS. All the patients received atlantoaxial reduction with the help of intraoperative skull traction and C1-C2 fixation. Clinical and radiological parameters were collected through chart review. Results There were 86 cases included in this study. The mean operative time was 153.9 ± 73.9 min, and the mean amount of intraoperative blood loss was 219.1 ± 195.6 ml. 81 patients underwent posterior reduction, internal fixation and fusion. 5 patients underwent anterior release, followed by posterior internal fixation and fusion. 82 patients got satisfactory postoperative outcomes while complications occurred in 4 patients. Significant neurologic improvement was observed in these patients. Bone fusion was achieved on the midline sagittal reconstructed CT images at the latest follow-up in all these patients except 1 case. All the patients were followed up for 34.84 ± 15.86 months at average (range 12–60 months). The mean ADI value was 7.55 ± 1.67 mm at average preoperatively, and improved to 4.03 ± 1.21 mm postoperatively, and to 4.21 ± 0.99 mm at the latest follow-up. The mean A-A angle was 15.48 ± 9.82 degrees at average preoperatively, and improved to 21.61 ± 10.43 degrees postoperatively, and to 19.73 ± 8.13 degrees at the latest follow-up. The mean A-A height was 35.61 ± 7.66 mm at average preoperatively, and improved to 40.08 ± 8.5 mm postoperatively, and to 38.83 ± 6.97 mm at the latest follow-up. There were complications in 4 patients, including pedicle misplacement, pedicle screw fracture, infection and one death. Conclusion Intraoperative skull traction can effectively facilitate the surgical procedures for ASS caused by different etiologies. Further research will be needed to investigate the safety and effectiveness of this method in the future.

Abstract
A class of imidazoisoindole (III) heme-binding indoleamine-2,3-dioxygenase (IDO1) inhibitors were optimized via structure-based drug design into a series of tryptophan-2,3-dioxygenase (TDO)-selective inhibitors. Kynurenine pathway modulation was demonstrated in vivo, which enabled evaluation of TDO as a potential cancer immunotherapy target. As means of mitigating the risk of drug-drug interactions arising from cytochrome P450 inhibition, a novel property-based drug design parameter, herein referred to as the CYP Index, was implemented for the design of inhibitors with appreciable selectivity for TDO over CYP3A4. We anticipate the CYP Index will be a valuable design parameter for optimizing CYP inhibition of any small molecule inhibitor containing a Lewis basic motif capable of binding heme.

Abstract
The aims of this pilot study are to evaluate the feasibility, safety, and effectiveness of conducting an enhanced nutritional support pathway including extended preoperative nutritional support and one month home enteral nutrition (HEN) for patients who underwent enhanced recovery after esophagectomy. We implemented extended preoperative nutritional support and one month HEN after discharge for patients randomized into an enhanced nutrition group and implemented standard nutritional support for patients randomized into a conventional nutrition group. Except the nutritional support program, both group patients underwent the same standardized enhanced recovery after surgery programs of esophagectomy based on published guidelines. Patients were assessed at preoperative day, postoperative day 7 (POD7), and POD30 for perioperative outcomes and nutritional status. To facilitate the determination of an effect size for subsequent appropriately powered randomized clinical trials and assess the effectiveness, the primary outcome we chose was the weight change before and after esophagectomy. Other outcomes including body mass index (BMI), lean body mass (LBM), appendicular skeletal muscle mass index (ASMI), nutrition-related complications, and quality of life (QoL) were also analyzed. The intention-to-treat analysis of the 50 randomized patients showed that there was no significant difference in baseline characteristics. The weight (-2.03 ± 2.28 kg vs. -4.05 ± 3.13 kg, P = 0.012), BMI (-0.73 ± 0.79 kg/m2 vs. -1.48 ± 1.11 kg/m2, P = 0.008), and ASMI (-1.10 ± 0.37 kg/m2 vs. -1.60 ± 0.66 kg/m2, P = 0.010) loss of patients in the enhanced nutrition group were obviously decreased compared to the conventional nutrition group at POD30. In particular, LBM (48.90 ± 9.69 kg vs. 41.96 ± 9.37 kg, p = 0.031) and ASMI (7.56 ± 1.07 kg/m2 vs. 6.50 ± 0.97 kg/m2, P = 0.003) in the enhanced nutrition group were significantly higher compared to the conventional nutrition group at POD30, despite no significant change between pre- and postoperation. In addition, European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 scores revealed that enhanced nutritional support improved the QoL of patients in physical function (75.13 ± 9.72 vs. 68.33 ± 7.68, P = 0.009) and fatigue symptom (42.27 ± 9.93 vs. 49.07 ± 11.33, P = 0.028) compared to conventional nutritional support. This pilot study demonstrated that an enhanced nutritional support pathway including extended preoperative nutritional support and HEN was feasible, safe, and might be beneficial to patients who underwent enhanced recovery after esophagectomy. An appropriately powered trial is warranted to confirm the efficacy of this approach.

Abstract
AIM To investigate computed tomography (CT), magnetic resonance imaging (MRI), and combined 2-[18F]-fluoro-2-deoxy-d-glucose (18F-FDG) positron-emission tomography (PET)/CT features of pancreatic sarcomatoid carcinoma (PSC). MATERIALS AND METHODS The hospital database was searched retrospectively for the patients with PSC confirmed at histopathology after surgery. Ten patients who underwent unenhanced and enhanced CT (n=4), unenhanced and enhanced MRI (n=2), 18F-FDG PET/CT (n=2), and both enhanced CT and 18F-FDG PET/CT (n=2) were enrolled. Two patients underwent additional delayed PET/CT. The maximum standardised uptake value (SUVmax) was measured on PET/CT images. RESULTS Eleven lesions were detected in 10 patients. Solid and cystic components (n=6), intratumoural haemorrhage (n=1), nodular calcification (n=2), main pancreatic duct dilatation resulted from lesion obstruction (n=5) or compression (n=3), cholangiectasis (n=5), vascular and peripheral organ invasion (n=5 and 6, respectively), hepatic and lymphatic metastases (n=4 and 2, respectively) were detected. All five lesions in four patients who underwent PET/CT showed intense FDG uptake on PET/CT with SUVmax (16, range 10.9-21.1). Increase of FDG uptake (SUVmax = 18.9, 20.1, and 27.3, respectively) was revealed on the delayed scan of three lesions in two patients. CONCLUSIONS PSCs were more commonly ill-defined solid cystic masses, which caused pancreatic duct obstruction/compression without pancreatic parenchymal atrophy, and these masses on PET/CT showed high FDG uptake on both initial and delayed PET/CT.

Abstract
FLOWERING LOCUS T (FT) is a key integrator of environmental signals and internal cues, and codes for florigen-like activity which regulates the transition from vegetative to reproductive growth in flowering plants. Unlike annual plants, perennial tree species undergo several years of vegetative growth prior to the transition to the reproductive stage, as characterised by the ability to form flower buds. Thereafter, trees in temperate regions typically display an annual growth cycle involving distinct vegetative growth, flowering and dormancy stages. In London plane (Platanus acerifolia Willd.), a FT-like gene has previously been identified. Here, we report the isolation of a novel FT orthologous gene, PaFTL, and investigate the functions of PaFT and PaFTL through the analysis of expression profiles and transgenic phenotypes. PaFT displayed the highest levels of expression during tree dormancy, and similarly elevated expression levels were seen under conditions of low temperature and short days (LT/SD). In contrast, PaFTL transcripts were up-regulated during the floral transition phase, the early stages of inflorescence development and throughout the main flowering period, whereas expression levels were low and variable during dormancy and in response to LT/SD treatments. Ectopic expression of 35s::PaFTL in tobacco produced a phenotype similar to that with PaFT, namely, advanced floral initiation. Overall, the results suggest that PaFT and PaFTL have both conserved and diverse functions in floral initiation, floral development and dormancy regulation.

Abstract
Objective: To explore the effect of pirfenidone in fibrotic interstitial pneumonia with autoimmune features (IPAF) after treatment with corticosteroids and immunosuppressants. Methods: We conducted a retrospective analysis of 2 adult patients with IPAF in the Peking Union Medical College Hospital. As their fibrotic interstitial lung disease failed to improve with further treatment with corticosteroids and immunosuppressants, they were treated with pirfenidone based on corticosteroids and immunosuppressants. Their clinical, chest radiological data and prognosis were collected and relevant literatures were reviewed. Results: One patient was a 43 year old female, the other was a 53 year old male. IPAF was diagnosed with their classic clinical, serological and radiological features. They were partially responded to corticosteroids and immunosuppressants at the initial period. Pirfenidone was suggested for them as their lung fibrosis was not improved further with immunosuppressive therapy. After 4-5 months treatment with pirfenidone, based on corticosteroids and immunosuppressant administration, their clinical and radiological manifestations improved significantly. Conclusions: Pirfenidone might be a good add-on choice for fibrotic IPAF when the disease did not respond well to corticosteroids and immunosuppressants.
