Abstract
Objective: To explore the molecular mechanism of circDDX17 regulating the proliferation and apoptosis of non-small cell lung cancer cells by targeting the miR-223-3p/RIP3 molecular axis. Methods: The expression levels of circDDX17, miR-223-3p, and RIP3 in human normal lung epithelial cell lines BEAS-2B and non-small cell lung cancer cells H1299, A549, and H446 were detected by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR). The plasmids of pcDNA, pcDNA-circDDX17, anti-miR-con, anti-miR-223-3p, pcDNA-circDDX17 and miR-con, pcDNA-circDDX17 and miR-223-3p mimics were transfected into H1299 cells. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide (MTT) assay was used to detect the cell proliferation. Flow cytometry was used to detect the cell cycle and cell apoptosis. Plate cloning experiment was used to detect cell proliferation ability. The dual luciferase report experiment was applied to verify the targeting relationship between miR-223-3p with circDDX17 and RIP3. Western blot was used to detect the protein expression of cyclinD1, CDK2, cleaved caspase-3 and Bax. Results: The expression levels of circDDX17 and RIP3 mRNA in H1299, A549, and H446 cells were significantly reduced (P<0.05), the expression level of miR-223-3p mRNA was significantly increased (P<0.05) compared with BEAS-2B. The cell viability [(69.46±4.68)%], the number of cell clones (83.49±7.86), the proportion of cells in S phase [(22.52±1.41) %], the protein expression levels of cyclinD1 and CDK2 in PCDNa-CircDDX17 group were lower than those in pcDNA group [(97.54±7.72)%, 205.03±13.37, (28.69±1.49)%, respectively, P<0.05], while the percentage of G0/G1 phase cells [(64.45±3.56)%], apoptosis rate [(18.36±1.63)%], the protein expression levels of cleaved caspase-3 and Bax in pcDNA-circDDX17 group were higher than those of pcDNA group [(51.33±2.76) % and (5.21±0.54) %, respectively, P<0.05]. The viability [(72.64±5.44)%], the number of cell clones (78.16±8.23), the proportion of S-stage cells [(21.34±1.59) %], the protein expression levels of CyclinD1 and CDK2 in anti-miR-223-3p group were lower than those in anti-miR-con group [(103.47±6.25)%, 169.32±14.53, (28.43±1.26)%, respectively, P<0.05]. Percentage of G0/G1 phase cells [(62.86±3.28)%], apoptosis rate [(14.64±1.67)%], the protein expression levels of cleaved caspase-3 and Bax in the anti-miR-223-3p group were higher than those of anti-miR-con group [(51.33±2.71)% and (4.83±0.39)%, respectively, P<0.05]. MiR-223-3p has complementary sites with circDDX17 or RIP3. The viability [(135.45±9.28)%], the number of cell clones (174.64±10.68), the proportion of S-phase cells [(26.39±2.25)%], the protein expression levels of cyclinD1 and CDK2 in pcDNA-circDDX17+miR-223-3p group were higher than those in pcDNA-circDDX17+miR-con group [(101.56±6.68)%, 107.65±7.62, (21.64±1.72)%, P<0.05]. Percentage of G0/G1 phase cells [(56.64±2.76)%], apoptosis rate [(8.34±0.76)%], the protein expression levels of cleaved caspase-3 and Bax in pcDNA-circDDX17+miR-223-3p group were lower than those of pcDNA-circDDX17+miR-con group [(64.03±3.48)% and (15.21±1.18)%, respectively, P<0.05]. Conclusion: circDDX17 could inhibit the proliferation and induce apoptosis of non-small cell lung cancer cells via targeting the miR-223-3p / RIP3 molecular axis.

Abstract
BACKGROUND Some medical conditions may increase the risk of developing pulmonary tuberculosis (PTB); however, no systematic study on PTB-associated comorbidities and comorbidity clusters has been undertaken. METHODS A nested case-control study was conducted from 2013 to 2017 using multi-source big data. We defined cases as patients with incident PTB, and we matched each case with four event-free controls using propensity score matching (PSM). Comorbidities diagnosed prior to PTB were defined with the International Classification of Diseases-10 (ICD-10). The longitudinal relationships between multimorbidity burden and PTB were analyzed using a generalized estimating equation. The associations between PTB and 30 comorbidities were examined using conditional logistic regression, and the comorbidity clusters were identified using network analysis. RESULTS A total of 4265 cases and 17,060 controls were enrolled during the study period. A total of 849 (19.91%) cases and 1141 (6.69%) controls were multimorbid before the index date. Having 1, 2, and ≥ 3 comorbidities was associated with an increased risk of PTB (aOR 2.85-5.16). Fourteen out of thirty comorbidities were significantly associated with PTB (aOR 1.28-7.27), and the associations differed by sex and age. Network analysis identified three major clusters, mainly in the respiratory, circulatory, and endocrine/metabolic systems, in PTB cases. CONCLUSIONS Certain comorbidities involving multiple systems may significantly increase the risk of PTB. Enhanced awareness and surveillance of comorbidity are warranted to ensure early prevention and timely control of PTB.

Abstract
OBJECTIVE To discuss the value of computed tomography (CT) iterative reconstruction technique combined with target scanning in the diagnosis of solid pseudopapillary tumor of the pancreas (SPTP). METHODS The clinical information and CT examination data of 27 patients with SPTP were retrospectively analyzed, and the general condition and CT performance of the patients were observed. The CT image reconstruction algorithm of all patients used iterative reconstruction technique combined with the application of target scanning technique. RESULTS A total of 27 patients were included in this study, including 6 males and 21 females, aged 14-72 years with a mean age of 39.6 ± 13.6 years. SPTP was more common in young and middle-aged females, with a low level of tumor markers, dominated by cystic-solid tumors. The combination of CT iterative reconstruction technology and targeted scanning revealed the following: the capsule of SPTP was clear and complete, where calcifications were visible, solid components were progressively enhanced, and rare pancreatic and bile duct dilation was seen. Tumors were cystic-solid in 18 of 27 patients with SPTP, of which the solid components showed isodensity or slightly low-density, with calcifications. The solid components and cyst walls were mildly enhanced during the arterial phase, and were progressively enhanced during the parenchymal phase, portal vein phase, and delayed phase, with their enhancement degree lower than that of normal pancreatic parenchyma, and pancreatic and bile duct dilation was rare. There were no statistical differences in tumor location, morphology, growth pattern, integrity of capsule, cystic or solid, calcifications, and enhancement features between the male group and the female group (P > 0.05). CONCLUSION The iterative reconstruction combined with target scanning clearly displayed the CT features of tumors, helping the diagnosis and clinical treatment of the disease.

Abstract
OBJECTIVE To investigate the diagnostic value of computed tomography (CT) and magnetic resonance imaging (MRI) in ovarian malignant mesothelioma (OMM). METHODS The clinical and imaging data of 10 pathologically-confirmed OMM patients were analyzed retrospectively. RESULT (1) The patients were 27 years to 70 years old, with an average age of 57.2 ± 15.4 years. Seven patients reported abdominal distension and pain, 1 reported lower abdominal discomfort and decreased appetite, and 2 patients had no symptoms. (2) Two cases of localized OMM with incomplete semi-annular "capsule" observed around the localized OMM tumors were reported while 8 cases had diffuse OMM in which the tumor parenchyma showed isointense or slightly hypointense on T1WI, inhomogeneous hyperintense on T2WI, and obviously hyperintense on DWI, with obvious inhomogeneous enhancement after enhancement. Diffuse OMM was not mainly composed of ovarian masses and was mainly characterized by mild ovarian enlargement, nodular and irregular thickening of the peritoneum, cloudy omentum, unclear fat gap, and reticular or irregular thickening, which can fuse into a "cake-shape". (3) All 10 patients underwent surgery, while 9 patients underwent systemic chemotherapy or immunotherapy after surgery. All patients with localized OMM survived. Out of the 8 diffuse-type patients, 5 died, 1 was lost to follow-up, and 2 survived. CONCLUSION OMM has certain clinical and imaging characteristics. There is no liquefaction, calcification, or partition in the tumor. The ovarian enlargement in the diffuse lesion is not significant. The diffuse thickening of the peritoneum and omentum with early appearance of mural nodules and ascites in the upper abdomen, help the diagnosis of OMM.

Abstract
In view of the superior chemical activity of selenoether bond (-Se-) and the excellent optical properties of naphthimide, a novel fluorescent probe (NapSe) with near-rectangular structure, which contains double naphthimide fluorophores linked by selenoether bond, is designed for specific fluorescence detection of hydrogen sulfide (H2S). NapSe has excellent optical properties: super large Stokes Shift (190 nm) and good stability in a wide pH range. The selectivity of NapSe fluorescence detection of H2S is high, and displays excellent "turn-on" phenomenon and strong anti-interference. And the fluorescence intensity increased obviously, reaching 42 times. The time response of probe NapSe is very rapid (3 min) compared with other fluorescence probes that respond to H2S. It shows high sensitivity by calculating the detection limit (LOD) as low as 5.4 μM. Notably, the identification of H2S by probe NapSe has been successfully applied to the detection of test paper and the detection of exogenous and endogenous fluorescence imaging of MCF-7 breast cancer cells.

Abstract
Objective: To compare the clinical effects of endoscopic thyroidectomy using a modified gasless transsubclavian approach and the traditional neck approach for unilateral papillary thyroid carcinoma (cN0). Methods: The clinical data of 135 patients with cN0 papillary thyroid carcinoma who underwent unilateral thyroidectomy in the Department of Thyroid Surgery, the First Hospital of Jilin University from October 2020 to November 2022 were retrospectively analyzed. There were 37 males and 98 females, aging (43.2±8.8) years (range: 21 to 59 years). There were 51 cases using the modified gasless transsubclavian approach (TS group) and 84 cases using the traditional neck approach (TN group). Comparative analyses were performed between the operative results of the 2 groups by t-test, Wilcoxon rank sum test, and χ2 test. Results: All endoscopic operations were successfully completed without conversion to the traditional neck approach. Compared to the TN group, the TS group had a longer operation time (M(IQR)) (73.5 (22.5) minutes vs. 90.0 (30.0) minutes, Z=-5.831, P<0.01), more postoperative drainage (60 (25) ml vs. 95 (45) ml, Z=-6.275, P<0.01), higher hospitalization costs (22 687 (3 488) yuan vs. 26 652 (2 431) yuan, Z=-6.944, P<0.01), and a higher rate of parathyroid autotransplantation (15.5% (13/84) vs. 60.8% (31/51), χ2=29.651, P<0.01). There was no significant difference in the total exposure rate of the central compartment, postoperative hospitalization time, the number of dissected lymph nodes, the number of metastatic lymph nodes, C-reactive protein ratio before and after operation, and preoperative and postoperative parathyroid hormone (all P>0.05). Conclusion: Endoscopic thyroidectomy using the modified gasless transsubclavian approach is safe for cN0 papillary thyroid carcinoma, with longer operating time, more postoperative drainage, higher hospitalization costs, and more difficulty in preserving the inferior parathyroid gland in situ compared to traditional open surgery.

Abstract
Objective: To compare the effects of two administration time strategies for rabbit antihuman thymocyte immunoglobulin (rATG) of 5mg/kg total dose in matched sibling donor hematopoietic stem cell transplantation (MSD-HSCT) . Methods: This study retrospectively analyzed the clinical data of 32 patients who received MSD-HSCT with 5 mg/kg rATG conditioning regimen at the Department of Hematology of the First Medical Center of the People's Liberation Army General Hospital from October 2020 to April 2022. The patients were classified into two groups: the 4d-rATG group (16 cases), who received antithymocyte globulin (ATG) from day -5 to day -2, and the 2d-rATG group (16 cases), who received ATG from day -5 to day -4. Between the two groups, the transplantation outcomes, serum concentrations of active antithymocyte globulin (ATG) in patients from -4 days to 28 days after graft infusion (+28 days), and the reconstitution of lymphocyte subsets on days +30, +60, and +90 were compared. Results: The cumulative incidences of acute graft-versus-host disease at 100 days after graft infusion were 25.0% (95% CI 7.8% -47.2% ) and 18.8% (95% CI 4.6% -40.2% ) (P=0.605) in the 4d-rATG group and 2d-rATG group, respectively. The 1-year cumulative incidences of chronic graft-versus-host disease were 25.9% (95% CI 8.0% -48.6% ) and 21.8% (95% CI 5.2% -45.7% ) (P=0.896). The 1-year cumulative incidence of relapse was 37.5% (95% CI 18.9% -65.1% ) and 14.6% (95% CI 3.6% -46.0% ) (P=0.135), and the 1-year probabilities of overall survival were 75.0% (95% CI 46.3% -89.8% ) and 100% (P=0.062). The total area under the curve (AUC) of serum active ATG was 36.11 UE/ml·d and 35.89 UE/ml·d in the 4d-rATG and 2d-rATG groups, respectively (P=0.984). The AUC was higher in the 4d-rATG group than that in the 2d-rATG group (20.76 UE/ml·d vs 15.95 UE/ml·d, P=0.047). Three months after graft infusion, the average absolute count of CD8(+) T lymphocytes in the 4d-rATG group was lower than that in the 2d-rATG group (623 cells/μl vs 852 cells/μl, P=0.037) . Conclusion: The efficiencies of GVHD prophylaxis in MSD-PBSCT receiving 4d-ATG regimen and the 2d-rATG regimen were found to be similar. The reconstruction of CD8(+)T lymphocytes in the 2d-rATG group was better than that in the 4d-rATG group, which is related to the lower AUC of active ATG after transplantation.

Abstract
Mg-1 wt.% Li-1 wt.% Ca (LX11) and Mg-4 wt.% Li-1 wt.% Ca (LX41) alloys share the same hexagonal closed-packed crystalline structure. However, the differences in microstructure, mechanical properties, and degradation rates between the two alloys are not well understood. Hereby, the above three aspects of LX11 and LX41 alloys were studied via optical microscopy, tensile tests, and electrochemical polarization and electrochemical impedance spectroscopy, together with hydrogen evolution. The concentration of the released Mg2+, Ca2+, and Li+ ions was analyzed using a flame atomic absorption spectrophotometer. Results demonstrated that the LX11 alloy was composed of finer α-Mg grains, fewer twins, and smaller volume fractions of the intermetallic phases Mg2Ca than the LX41 alloy. The increasing Li concentration generated a weak decrease in the yield strength of the Mg-Li-Ca alloys, a remarkable increase in elongation to failure, and a stable ultimate tensile strength. The LX11 alloy had better corrosion resistance than the LX41 alloy. The release rate of the cations (Mg2+, Ca2+, and Li+) varied significantly with time. The release rate of metallic ions in Hank's solution cannot reflect the true corrosion rate of Mg-Li-Ca alloys due to the formation of the precipitated corrosion products and their difference in solubility. The dealloying corrosion mechanism of the Mg2Ca phase in Mg-Li-Ca alloys was proposed.

Abstract
Objective: To investigate the features of contrast-enhanced ultrasound (CEUS) in hepatic epithelioid hemangioendothelioma (HEHE) in order to improve the preoperative diagnosis rate. Methods: CEUS images of 32 pathologically-proven cases of hepatic epithelioid hemangioendothelioma from January 2004 to August 2021 were collected. Lesions were analyzed to observe the features of enhancement mode, enhancement intensity, and distinct enhancement phases. Results: Among the 32 cases, one had a solitary lesion, 29 had multiple lesions, and two had diffuse-type lesions. Contrast-enhanced ultrasound revealed a total of 42 lesions in 32 cases. In terms of arterial phase enhancement, 18 lesions had overall enhancement, six lesions had uneven dendritic enhancement, 16 lesions had rim-like enhancement, and two lesions had just slight peripheral spot enhancement around the lesions. Among the three cases, there were multiple lesions that had overall enhancement and ring enhancement. In terms of the enhancement phase, 20 lesions showed "fast progression", 20 lesions showed "same progression", and two lesions showed "slow progression". During the late arterial or early portal venous phases with rapid washout, all lesions manifested as hypoechoic. With peaked enhanced intensity, 11 lesions had a lower enhancement intensity than the surrounding normal liver parenchyma; 11 lesions had the same enhancement degree as the surrounding normal liver parenchyma; and 20 lesions had a higher enhancement degree than the surrounding normal liver parenchyma. All 16 ring-enhancing lesions had marked hyperenhancement. In the typical enhancing lesions, four showed hyperenhancement, five showed low enhancement, and nine showed isoenhancement. In the dendrite-enhancing lesions, there were two isoenhancing and four hypoenhancing. Contrast-enhanced ultrasound delineated the boundaries of all lesions more clearly than two-dimensional ultrasound. Conclusion: Contrast-enhanced ultrasound has certain value in the diagnosis of hepatic epithelioid hemangioendothelioma.

Abstract
BACKGROUND Circular RNAs (circRNAs) have attracted extensive attention as therapeutic targets in gastric cancer (GC). Circ_0003356 is known to be downregulated in GC tissues, but its cellular function and mechanisms remain undefined.
AIM To investigate the role of circ_0003356 in GC at the molecular and cellular level.
METHODS Circ_0003356, miR-668-3p, and SOCS3 expression were assessed via quantitative real time-polymerase chain reaction (qRT-PCR). Wound healing, EdU, CCK-8, flow cytometry and transwell assays were used to analyze the migration, proliferation, viability, apoptosis and invasion of GC cells. The subcellular localization of circ_0003356 was monitored using fluorescence in situ hybridization. The interaction of circ_0003356 with miR-668-3p was confirmed using RIP-qRT-PCR, RNA pull-down, and dual luciferase reporter assays. We observed protein levels of genes via western blot. We injected AGS cells into the upper back of mice and performed immunohistochemistry staining for examining E-cadherin, N-cadherin, Ki67, and SOCS3 expressions. TUNEL staining was performed for the assessment of apoptosis in mouse tumor tissues.
RESULTS Circ_0003356 and SOCS3 expression was downregulated in GC cells, whilst miR-668-3p was upregulated. Exogenous circ_0003356 expression and miR-668-3p silencing suppressed the migration, viability, proliferation, epithelial to mesenchy-mal transition (EMT) and invasion of GC cells and enhanced apoptosis. Circ_0003356 overexpression impaired tumor growth in xenograft mice. Targeting of miR-668-3p by circ_0003356 was confirmed through binding assays and SOCS3 was identified as a downstream target of miR-668-3p. The impacts of circ_0003356 on cell proliferation, apoptosis, migration, invasion and EMT were reversed by miR-668-3p up-regulation or SOCS3 down-regulation in GC cells.
CONCLUSION Circ_0003356 impaired GC development through its interaction with the miR-668-3p/SOCS3 axis.

Abstract
BACKGROUND Pancreaticoduodenectomy combined with portal vein (PV) and/or superior mesenteric vein (SMV) resection in patients with pancreaticobiliary malignancy has become a common surgical procedure. There are various grafts currently used for PV and/or SMV reconstruction, but each of these grafts have certain limitations. Therefore, it is necessary to explore novel grafts that have an extensive resource pool, are low cost with good clinical application, and are without immune response rejection or additional damage to patients.
AIM To observe the anatomical and histological characteristics of the ligamentum teres hepatis (LTH) and evaluate PV/SMV reconstruction using an autologous LTH graft in pancreaticobiliary malignancy patients.
METHODS In 107 patients, the post-dilated length and diameter in resected LTH specimens were measured. The general structure of the LTH specimens was observed by hematoxylin and eosin (HE) staining. Collagen fibers (CFs), elastic fibers (EFs), and smooth muscle (SM) were visualized by Verhoeff-Van Gieson staining, and the expression of CD34, factor VIII-related antigen (FVIIIAg), endothelial nitric oxide synthase (eNOS), and tissue type plasminogen activator (t-PA) were detected using immunohistochemistry in LTH and PV (control) endothelial cells. PV and/or SMV reconstruction using the autologous LTH was conducted in 26 patients with pancreaticobiliary malignancies, and the outcomes were retrospectively analyzed.
RESULTS The post-dilated length of LTH was 9.67 ± 1.43 cm, and the diameter at a pressure of 30 cm H2O was 12.82 ± 1.32 mm at the cranial end and 7.06 ± 1.88 mm at the caudal end. Residual cavities with smooth tunica intima covered by endothelial cells were found in HE-stained LTH specimens. The relative amounts of EFs, CFs and SM in the LTH were similar to those in the PV [EF (%): 11.23 ± 3.40 vs 11.57 ± 2.80, P = 0.62; CF (%): 33.51 ± 7.71 vs 32.11 ± 4.82, P = 0.33; SM (%): 15.61 ± 5.26 vs 16.74 ± 4.83, P = 0.32]. CD34, FVIIIAg, eNOS, and t-PA were expressed in both LTH and PV endothelial cells. The PV and/or SMV reconstructions were successfully completed in all patients. The overall morbidity and mortality rates were 38.46% and 7.69%, respectively. There were no graft-related complications. The postoperative vein stenosis rates at 2 wk, 1 mo, 3 mo and 1 year were 7.69%, 11.54%, 15.38% and 19.23%, respectively. In all 5 patients affected, the degree of vascular stenosis was less than half of the reconstructed vein lumen diameter (mild stenosis), and the vessels remained patent.
CONCLUSION The anatomical and histological characteristics of LTH were similar to the PV and SMV. As such, the LTH can be used as an autologous graft for PV and/or SMV reconstruction in pancreaticobiliary malignancy patients who require PV and/or SMV resection.

Abstract
Proper defense against microbial infection depends on the controlled activation of the immune system. This is particularly important for the RIG-I-like receptors (RLRs), which recognize viral dsRNA and initiate antiviral innate immune responses with the potential of triggering systemic inflammation and immunopathology. Here, we show that stress granules (SGs), molecular condensates that form in response to various stresses including viral dsRNA, play key roles in the controlled activation of RLR signaling. Without the SG nucleators G3BP1/2 and UBAP2L, dsRNA triggers excessive inflammation and immune-mediated apoptosis. In addition to exogenous dsRNA, host-derived dsRNA generated in response to ADAR1 deficiency is also controlled by SG biology. Intriguingly, SGs can function beyond immune control by suppressing viral replication independently of the RLR pathway. These observations thus highlight the multi-functional nature of SGs as cellular "shock absorbers" that converge on protecting cell homeostasis by dampening both toxic immune response and viral replication.

Abstract
Cannabidiol (CBD) reportedly exerts protective effects against many psychiatric disorders and neurodegenerative diseases, but the mechanisms are poorly understood. In this study, we explored the molecular mechanism of CBD against cerebral ischemia. HT-22 cells or primary cortical neurons were subjected to oxygen-glucose deprivation insult followed by reoxygenation (OGD/R). In both HT-22 cells and primary cortical neurons, CBD pretreatment (0.1, 0.3, 1 μM) dose-dependently attenuated OGD/R-induced cell death and mitochondrial dysfunction, ameliorated OGD/R-induced endoplasmic reticulum (ER) stress, and increased the mitofusin-2 (MFN2) protein level in HT-22 cells and primary cortical neurons. Knockdown of MFN2 abolished the protective effects of CBD. CBD pretreatment also suppressed OGD/R-induced binding of Parkin to MFN2 and subsequent ubiquitination of MFN2. Overexpression of Parkin blocked the effects of CBD in reducing MFN2 ubiquitination and reduced cell viability, whereas overexpressing MFN2 abolished Parkin's detrimental effects. In vivo experiments were conducted on male rats subjected to middle cerebral artery occlusion (MCAO) insult, and administration of CBD (2.5, 5 mg · kg-1, i.p.) dose-dependently reduced the infarct volume and ER stress in the brains. Moreover, the level of MFN2 within the ischemic penumbra of rats was increased by CBD treatment, while the binding of Parkin to MFN2 and the ubiquitination of MFN2 was decreased. Finally, short hairpin RNA against MFN2 reversed CBD's protective effects. Together, these results demonstrate that CBD protects brain neurons against cerebral ischemia by reducing MFN2 degradation via disrupting Parkin's binding to MFN2, indicating that MFN2 is a potential target for the treatment of cerebral ischemia.

Abstract
Melanoma is the most aggressive skin malignancy with high morbidity. Anti-programmed cell death protein 1 (PD-1) monotherapy has been applied in metastatic melanoma. However, still most of the patients do not respond to anti-PD-1 and the availability of the present approved biomarkers therefore is limited. Here we combined the transcriptomic and clinical data of 163 advanced melanoma patients receiving anti-PD-1 from NIH Melanoma Genome Sequencing Project (phs000452, 122 patients) as the training and internal validation cohort, and Melanoma Institute Australia cohort (PRJEB23709, 41 patients) as the external validation cohort, respectively. Circular RNAs (circRNAs) are an evolutionarily conserved novel class of noncoding endogenous RNAs (ncRNAs) found in the eukaryotic transcriptome and were used based on RNAseq data for our analyses. 74,243 circular RNAs (circRNAs) were identified with NCLscan and CIRCexplorer2. Thereof, 70 circRNAs significantly associated with progression-free survival and overall survival. Further, a prognostic circRNAs signature consisting of HSA_CIRCpedia_1497, HSA_CIRCpedia_12559, HSA_CIRCpedia_43640, HSA_CIRCpedia_43070, and HSA_CIRCpedia_21660 could be determined with LASSO regression. This signature was a prognostic factor of overall survival and progression-free survival among the analyzed advanced melanoma patients. The concordance indexes (C-index of OStraining: 0.61, C-index of PFStraining: 0.68) also confirmed its credibility and accuracy. First enrichment analysis indicated that immune response and pathways related to tumor immune microenvironment were enriched. In conclusion, we succeeded to construct and validate novel prognostic circRNAs signature for advanced melanoma patients treated with anti-PD-1 immunotherapy.

Abstract
In recent years, with the problem of aging population in China being prominant, the number of patients with chronic wounds such as diabetic foot, pressure ulcer, and vascular ulcer is increasing. Those diseases seriously affect the life quality of patients and increase the economy and care burden of the patients' family, which have been one of the most urgent clinical problems. Many researches have confirmed that adipose stem cells can effectively promote wound healing, while exogenous protease is needed, and there are ethical and many other problems, which limit the clinical application of adipose stem cells. Adipose stem cell matrix gel is a gel-like mixture of biologically active extracellular matrix and stromal vascular fragment obtained from adipose tissue by the principle of fluid whirlpool and flocculation precipitation. It contains rich adipose stem cells, hematopoietic stem cells, endothelial progenitor cells, and macrophages, etc. The preparation method of adipose stem cell matrix gel is simple and the preparation time is short, which is convenient for clinical application. Many studies at home and abroad showed that adipose stem cell matrix gel can effectively promote wound healing by regulating inflammatory reaction, promoting microvascular reconstruction and collagen synthesis. Therefore, this paper summarized the preparation of adipose stem cell matrix gel, the mechanism and problems of the matrix gel in promoting wound repair, in order to provide new methods and ideas for the treatment of chronic refractory wounds in clinic.

Abstract
Background/aims: Psychological and physiological stress can cause gastrointestinal motility disorders. Acupuncture has a benign regulatory effect on gastrointestinal motility. However, the mechanisms underlying these processes remain unclear. Methods: Herein, we established a gastric motility disorder (GMD) model in the context of restraint stress (RS) and irregular feeding. The activity of emotional center-central amygdala (CeA) GABAergic neurons and gastrointestinal center-dorsal vagal complex (DVC) neurons were recorded by electrophysiology. Virus tracing and patch clamp analysis of the anatomical and functional connection between the CeAGABA → dorsal vagal complex pathways were performed. Optogenetics inhibiting or activating CeAGABA neurons or the CeAGABA → dorsal vagal complex pathway were used to detect changes in gastric function. Results: We found that restraint stress induced delayed gastric emptying and decreased gastric motility and food intake. Simultaneously, restraint stress activated CeA GABAergic neurons, inhibiting dorsal vagal complex neurons, with electroacupuncture (EA) reversing this phenomenon. In addition, we identified an inhibitory pathway in which CeA GABAergic neurons project into the dorsal vagal complex. Furthermore, the use of optogenetic approaches inhibited CeAGABA neurons and the CeAGABA → dorsal vagal complex pathway in gastric motility disorder mice, which enhanced gastric movement and gastric emptying, whereas activation of the CeAGABA and CeAGABA → dorsal vagal complex pathway mimicked the symptoms of weakened gastric movement and delayed gastric emptying in naïve mice. Conclusion: Our findings indicate that the CeAGABA → dorsal vagal complex pathway may be involved in regulating gastric dysmotility under restraint stress conditions, and partially reveals the mechanism of electroacupuncture.

Abstract
Introduction Symptoms of gastric motility disorders are common clinical manifestations of functional gastrointestinal disorders (FGIDs), and are triggered and exacerbated by stress, but the neural pathways underpinning them remain unclear. Methods We set-up a mouse model by gastric dilation (GD) in which the gastric dynamics were assessed by installing strain gauges on the surface of the stomach. The neural pathway associated with gastric motility disorders was investigated by behavioral tests, electrophysiology, neural circuit tracing, and optogenetics and chemogenetics involving projections of the corticotropin-releasing hormone (CRH) from the paraventricular nucleus of the hypothalamus (PVN) to acetylcholine (ChAT) neurons in the dorsal motor nucleus of the vagus (DMV). Results We found that GD induced gastric motility disorders were accompanied by activation of PVN CRH neurons, which could be alleviated by strategies that inhibits the activity of PVN CRH neurons. In addition, we identified a neural pathway in which PVN CRH neurons project into DMV ChAT neurons, modulated activity of the PVN CRH →DMV ChAT pathway to alleviate gastric motility disorders induced by GD. Discussion These findings indicate that the PVN CRH →DMV ChAT pathway may mediate at least some aspects of GD related gastric motility, and provide new insights into the mechanisms by which somatic stimulation modulates the physiological functions of internal organs and systems.

Abstract
Externally bonded carbon-fiber-reinforced polymer (CFRP) technology can be used by different methods based on the anchorage device, CFRP type, and prestressing/nonprestressing. However, a direct comparison between the strengthening efficacies of different methods is still lacking. Seven large-scale RC beams were tested in this study to investigate the influences of the anchorage method, CFRP type, prestress, and prestressing system on the flexural strengthening efficacy of RC beams. The test results showed that the ultimate load increased by 38.3%, whereas the cracking and yielding loads were slightly affected when the anchorage method was enhanced from CFRP U-wraps to wedge-clamp anchors. The CFRP plate and CFRP sheet could provide a rather close flexural strengthening efficacy under the same CFRP strengthening amount. Compared to the nonprestressed CFRP plate, the prestressed CFRP plate was highly superior in improving the flexural behavior of RC beams. The cracking, yielding, and ultimate loads of the prestressed CFRP-strengthened specimens were 57.1%, 22.9%, and 5.9%, respectively, higher than those of the nonprestressed CFRP-strengthened specimen with an effective anchorage. The two types of prestressing systems based on the adhesive-friction anchor and wedge-clamp anchor were proven to be effective for flexural strengthening of RC beams with prestressed CFRP plates, and they could provide almost the same strengthening effect.

Abstract
BACKGROUND Postoperative pain treatment for pediatrics is often inadequate and the evidence of pediatric postoperative analgesia is scarce. To our knowledge, no report regarding the comparison among caudal block, transversus abdominis plane (TAP) block and quadratus lumborum (QL) block for children undergoing lower abdominal laparoscopic surgery was found at present. Thus this trial aimed to compare the efficacies of them for children undergoing lower abdominal laparoscopic surgery. METHODS One hundred and eighty children aged from 1 to 12 years undergoing lower abdominal laparoscopic surgery were included and randomized to receive caudal block, TAP block or QL block. The primary outcome was the Face, Legs, Activity, Cry, and Consolability (FLACC) score at 30 min, 1 h, 4 h, 8 h, 12 h, and 24 h and tramadol consumption during first 24 h postoperatively. Secondary outcomes included the number of children received tramadol, time to first tramadol request, parents' satisfaction and postoperative adverse reactions. RESULTS The QLB group had lower postoperative FLACC scores at 8 h (median difference - 0.43, P = 0.03) than the Caudal group and at 4 h (median difference - 0.6, P = 0.001) and 8 h (median difference - 0.43, P = 0.03) than the TAPB group. The tramadol consumption was lower in the QLB group (28.43 ± 6.55) than the TAPB group (37.17 ± 6.12, P = 0.023). Although the number of children received tramadol did not differ among the three groups, the time to first tramadol request was longer in the QLB group (7.20 ± 0.79) than the caudal group (8.42 ± 0.61, P = 0.008). No statistical difference was observed concerning other secondary outcomes. CONCLUSIONS QLB produced more effective postoperative analgesia for children undergoing laparoscopic abdominal surgery compared with the TAPB and caudal block.

Abstract
Acid fibroblast growth factor (aFGF) is a member of fibroblast growth factors (FGF) family, widely promoting embryonic development, wound healing, vascular regeneration, nerve injury repair, as well as regulating immune metabolism. Many pathophysiological processes, such as inflammation, neovascularization, proliferation and migration of repair cells, and deposition of collagen and other extracellular matrix are involved in the process of wound healing. Based on the relevant literature in recent years, this article mainly reviews the research progresses on the roles and mechanism of aFGF in biological signal transduction, regulation of cell growth, and involvement in tissue repair, and discusses the current research hot spots as well as the prospective future direction of clinical applications of aFGF in the aspect of clinical pharmacokinetics and safety.

Abstract
e16560 Background: Concordance between tumor DNA (tDNA) and urine tumor DNA (utDNA) profiles using paired samples was analyzed. Genomic analysis of utDNA and tDNA showed a high consistency, indicating that urine is an optional sample for noninvasive detection and response evaluation of bladder cancer (BC). Methods: Methods and results data were analyzed from an ongoing study, collecting all cases from Second Hospital Affiliated to Tianjin Medical University. Cases with pathologically confirmed BC and matching tissue/urine/whole blood before treatments were recruited. In 85 patients, 48 with paired samples were enrolled in this analysis after excluding 37 paired samples failed in sample QC or sample collection. WES (Whole Exome Sequence) was applied to tDNA and paired white blood cell (WBC) DNA. An Acornmed 808-Gene panel was applied to utDNA and paired WBC DNA. Somatic events, including SNV (single nucleotide variant), InDel (insertion and deletion) of hot genes were analyzed. Consistency of tDNA and utDNA were identified and analyzed in the intersection set between the two chips, and tDNA profiling was used as the“golden standard”. Results: Among 48 patients, 24(50.0%) were MIBC, 21(43.8%) were NMIBC and 41 (81.5%) were male. With neoadjuvant therapy, 23(47.9%) are identified as responders (CR or PR), 7(14.6%) identified as non-responders (SD or PD), 18(37.5%) are still following up. Overall, 75.4% (214/284) tDNA mutations were found in utDNA, and 75.1% (214/285) utDNA mutations were found in tDNA. The top20 genes’ mutation landscape of utDNA highly resembled that of tDNA. The top20 genes could cover 97.9% (47/48) tissue samples and 89.6% (43/48) urine samples. Also, top20 mutated genes showed a strong correlation between tDNA and utDNA(r = 0.7371, p = 0.0002). TP53, KMT2D, ARIDA1A, CREBBP, ERBB2, ERCC2 and KDM6A are the most frequent abnormalities captured in tDNA and utDNA. Interestingly, we also found that the consistency of top20 genes in responders (n = 23, r = 0.7015, p = 0.0006) are higher than non-responders (n = 7, r = 0.4118, p = 0.1853). As a consequence, 70.1% (157/224), 61.8% (21/34) tDNA mutations were found in utDNA, and 72.0% (157/218), 25.0% (21/84) utDNA mutations were found in tDNA in responders and in non-responders, respectively. Conclusions: In brief, utDNA was robustly consistent and highly associated with tDNA, with 61.8%̃75.4% tDNA variations detected in utDNA target sequecing by acornmed 808 panel. The consistency would be higher if TERT promoter included in WES panel. While in non-responders, only 25.0% utDNA mutations were found in tDNA, indicating a spatial and temporal tumor heterogeneity. Our data provided initial prospective evidence on further developing urine as an optional sample for noninvasive detection and response evaluation of BC. The large prospective cohort study is still ongoing.

Abstract
4507 Background: Pts with multiple or tumors with large invasion areas which are un-completely-resectable through TURBT would be recommended radical cystectomy in the clinical treatment. The KEYNOTE-057 study has illuminated the efficiency of immune checkpoint inhibitors monotherapy in HR-NMIBC pts, with acceptable adverse events (AEs). However, the role of PD-1/PD-L1 inhibitor in combination with chemotherapy in NMIBC pts remains unclear. We report preliminary treatment efficiency, safety data, and exploratory work of TRUCE-02 trial. Methods: TRUCE-02 is a phase II study for NMIBC pts with uncompletely resectable tumour by TURBT. The primary endpoint was complete response(absence of non-muscle-invasive bladder cancer or progressive disease). Pts that meet the criteria would receive tislelizumab 200mg on days 1 plus paclitaxel 200mg on days 2 every 3 weeks (Q3W) x 3 or 4 cycles followed by a comprehensive assessment including pathology, urine cytology, and imageology. Meanwhile, biomarker analyses included programmed death-ligand 1 (PD-L1) expression using the combined positive score (CPS; Dako 22C3 pharmDx assay) and whole transcriptome RNA sequencing of the tumor. Results: Between July 2020 and January 2022, 54 pts were enrolled. 42 pts have completed whole 3 or 4 treatment cycles and reached the primary endpoint. 23 pts achieved CR condition (56%, 95%CI, 43.6% and 74.4%). ORR of 60% (N=25/42, 95%CI, 45.2% and 74.8%). As a secondary endpoint, 33 pts remain cystectomy-free condition (78.6%, 95%CI, 66.2% and 91%). Grade 3-4 AEs were lower than 2%. Urine cytology showed its diagnostic efficiency of 68.42% (95%CI, 61.3% and 75.6%), urine FISH showed a diagnostic efficiency of 45.71% (95%CI, 37.7% and 53.4%) before pathological assessment. As for PD-L1 expression, 47.3% (N = 9/19) of response pts (CR+PR) showed positive, 50% (N = 5/10) of un-response pts (PD+SD) showed positive. We also found out through sequencing results that AR, TCF7L2 might be underlying markers that predict adverse outcomes for pts in this crew. HRR mutation may predict a positive prognosis and mutations in NMIBC which might predict the prognosis of this treatment plan. Conclusions: Tislelizumab with nab-paclitaxel represents a novel treatment option with a satisfactory benefit in treating NMIBC. PD-L1 expression has no obvious correlation with the efficiency of this treatment plan. WGS result also showed that there are mutation markers that may predict whether pts would benefit from this treatment plan. Clinical trial information: NCT04730232. [Table: see text]

Abstract
4590 Background: Urine cytology is a noninvasive and relatively inexpensive approach that plays an important role in both screening/initial diagnosis of urothelial carcinoma, and surveillance of tumor recurrence; However, interpretation of urine cytology is labor-intensive and time-consuming. Artificial intelligence (AI) has been widely used in the field of medically assisted diagnosis, but it is almost blank in the field of urothelial carcinoma diagnosis based on urine cytology. In this study, artificial intelligence (AI) algorithms have been developed to efficiently and automatically analyze urinary cytological specimens stained with Acridine orange fluorescence for screening and diagnosis of urothelial carcinoma with a good clinical application prospect. Methods: To develop the algorithms, images of urinary cytological specimens with Acridine orange Fluorescence staining were collected from patients who underwent examination, surgery, or both at the Second Hospital of Tianjin Medical University from August 2015 to August 2021. To standardize the urine cytological determination, the images were determined by 3 certified and experienced cytopathologists in this hospital. Images were collected to establish a dataset containing two major categories: Malignant (Defined as images containing malignant cells) and Benign (Defined as images containing malignant cells). From the acquired database, 2794 malignant and 2787 benign eligible images were selected for AI training/validation/testing. Inception V3, a specific type of neural network optimized for image classification called a deep convolutional neural network was trained based on the database. To prevent the model from over-fitting during training, data augmentation methods, such as rotation and flipping were adopted. The diagnosing performance of the binary classification model was analyzed using accuracy, F1 score, operating characteristic (ROC), and the area under the curve (AUC) generated from the sensitivity and specificity to evaluate. Results: A total of 21022 slides of urine cytological specimens with Acridine orange Fluorescence staining were collected. The AI algorithms achieved excellent performance, which showed the best prediction with an accuracy of 92.25%, a sensitivity of 98.50% along with a specificity of 86.00%, the F1score was 0.9271, and the area under the ROC curve was 0.96. Conclusions: Our novel artificial intelligence algorithms could accurately classify urine specimens as malignant or benign efficiently and automatically. The use of AI during cytopathology screening provides a new strategy and technical support for the diagnosis and screen of urothelial carcinoma. [Table: see text]

Abstract
e14563 Background: Bladder cancer is a molecularly diverse disease with heterogeneous clinical outcomes. Transcriptome-based molecular subtypes of muscle invasive bladder cancer (MIBC) and non-muscle invasive bladder cancer (NMIBC) have been shown to be both prognostic and predictive. However, its predictive role in Chinese bladder cancer remains unclear. The aim of this study was to identify the predictive role of molecular subtypes in China bladder cancer with neoadjuvant therapy. Methods: The study was conducted from May 2020 to August 2021. Patients who were age 18 years or older, were diagnosed with NMIBC or MIBC, and neoadjuvant tislelizumab combining nab-paclitaxel followed by surgery were included. Multigenomic sequencing was performed. Molecular subtypes were identified by published consensus. Results: We prospectively recruited 30 patients for neoadjuvant tislelizumab combining nab-paclitaxel, including 14 patients with NMIBC and 16 patients with MIBC. For bladder cancer, 73.3% (22/33) patients responded to neoadjuvant tislelizumab combining nab-paclitaxel. In NMIBC groups, 64.3% (9/14) patients were pCR. The objective remission rate ( ORR) was 71.4%. 4 molecular classes were identified in Chinese NMIBC, including class 1 (7.1%), class 2a (35.7%), class 2b (50%), class 3 (7.1%). Interesting, ORR was significantly higher for patients with class 2b (5/7, 71.4%) as compared to class 2a (3/5,60%) before neoadjuvant. Molecular classes changed in 35.7% (5/14) of patients before and after neoadjuvant. After neoadjuvant, 80% of class 2b patients responded to neoadjuvant, and all class 2a patients did not respond to neoadjuvant. In MIBC groups, a pPR was achieved by 37.5% patients (6/16). The ORR was 75%. We found 4 molecular classes in Chinese MIBC: basal/squamous (43.8%), luminal unstable (25%), luminal papillary (25%), and stroma-rich (6.2%). Patients with basal/squamous (85.7%) and luminal unstable (75%) had significantly higher ORR than luminal papillary (50%) before neoadjuvant. Molecular classes changed in 44.4% (4/9) of patients before and after neoadjuvant. After neoadjuvant, all patients with stroma-rich responded to neoadjuvant. Conclusions: Molecular classification could predict the efficacy of neoadjuvant tislelizumab combining nab-paclitaxel in Chinese bladder cancer, which may be preferable when studying biomarkers of bladder cancer in the future.

Abstract
4589 Background: The current strategy for bladder preservation is focused on trimodality treatment, including complete transurethral resection of bladder tumor (cTURBT), with concurrent chemotherapy and radiotherapy. Chemotherapy is usually a cisplatin-based regimen. However, many pts cannot tolerate cisplatin-based chemotherapy and radiation therapy. It fails to meet clinical needs. Meanwhile, the efficacy and safety of checkpoint inhibitors (ICIs) have now been demonstrated. We conduct a study to evaluate ICIs in combination with second-line chemotherapy agents for patients with MIBC. Methods: TRUCE-01 is a phase II trial (NCT04730219) of tislelizumab combined with nab-paclitaxel before cTURBT or radical cystectomy. Pts with pure or mixed urothelial bladder cancer (T2-4a Nx M0) received tislelizumab 200mg on days 1 plus paclitaxel 200mg on days 2 every 3 weeks (Q3W) x 3 cycles followed by cTURBT or radical cystectomy. Imaging evaluation is usually done before and after the drug administration using the same tests to assess the efficacy. Pts who choose to preserve bladder usually continue their medication after cTURBT. This abstract focuses on patients with bladder preservation. Results: Between July 2020 and November 2021, 47 pts completed at least 2 cycles of treatment, 22 (47%) pts received cTURBT, 16 (34%) pts received radical cystectomy and 9 (19%) pts refuse surgery. As for radiological response, 22 achieved complete response (CR), 16 achieved partial response (PR). In the bladder-preserving subgroup, 13 CR pts and 9 PR pts selected cTURBT, pathology showed 17 pT0, 1 pTa, 3 pT1 and 1 pTis. The median medication cycle is 9 (6-11). There were 3 pts experienced grade 3-4 adverse events (CTCAE), a grade 3 rash, a grade 3 gastric perforation and a grade 4 acute renal failure. In addition, The most common grade 1-2 adverse events include alopecia (86%), fatigue (77%), rash (41%), appetite decreases (41%), hyperglycemia (36%), fever (18%), and creatinine increased (14%). Median follow-up 357 (438-291) days with 3 recurrences and 1 death. The 1-year recurrence-free survival rate was 82%. Conclusions: The early efficacy data further support the role of tislelizumab combined with paclitaxel in bladder preservation setting with an acceptable adverse events. Patients with imaging CR or PR after neoadjuvant therapy are preferred for bladder preservation. Enrollment is ongoing. Clinical trial information: NCT04730219.

Abstract
Three strains of members of the family Bacillaceae, which can inhibit the growth of some Gram-stain-positive strains, designated M4U3P1T, HD4P25T and RD4P76T, were isolated from Suaeda salsa halophytes in Baotou, Inner Mongolia, PR China. A phylogenetic analysis based on the 16S rRNA gene and the whole genome sequences revealed that HD4P25T clustered with Cytobacillus luteolus YIM 93174T with a similarity of 98.4 %, and RD4P76T shared the highest similarity of 16S rRNA gene with Bacillus mesophilus SA4T (97.5 %). M4U3P1T clustered with strains of genera Salipaludibacillus and Alkalicoccus based on whole-genome sequence analyses, but its 16S rRNA gene had the highest similarity to 'Evansella tamaricis' EGI 80668 (96.1 %). The average nucleotide's identity by blast (ANIb) and digital DNA-DNA hybridization (dDDH) values of the three isolated strains to their close relatives were well below the threshold value for identifying a novel species.On the basis of the phylogenetic, physiological and phenotypic results, Paenalkalicoccus suaedae gen. nov., sp. nov. [type strain M4U3P1T (=CGMCC 1.17076T=JCM 33851T)], Cytobacillus suaedae sp. nov. [type strain HD4P25T (=CGMCC 1.18651T =JCM 34524T)], and Bacillus suaedae sp. nov. [type strain RD4P76T (=CGMCC 1.18659T=JCM 34525T)] were proposed, respectively. All three species are ubiquitous in the bulk saline-alkaline soils, but only the species represented by strain RD4P76T was widely distributed in the rhizosphere soil, the above-ground part and the roots of S. salsa. The species represented by M4U3P1T can be detected in the roots of S. salsa, and rarely detected in the above-ground parts of S. salsa. The species represented by HD4P25T was rarely detected in the interior of S. salsa. The three strains could inhibit some of the Gram-stain-positive bacteria (i.e. members of the genera Planococcus, Zhihengliuella and Sanguibacter) in the saline-alkali soil. A genomic analysis of these three strains revealed that they can synthesize different antagonistic compounds, such as aminobenzoate and bacitracin or subtilisin.

Abstract
Objective: To investigate the sensitization characteristics of Juniperus chinensis pollen in patients with allergic rhinitis and/or allergic asthma in Beijing area, and to explore the characteristics of Juniper chinensis pollen sensitized population. Methods: Patients with suspected allergic rhinitis and/or asthma from January 2017 to December 2019 in the outpatient department of Allergy Department of Beijing Shijitan Hospital were selected in this study. Skin prick test (SPT) was performed with Juniper chinensis pollen allergen reagent to compare different age and disease allergen distribution, and to observe the sensitization characteristics of its population. All of the analyses were performed using SAS software version 9.4. Results: A total of 8 380 patients were enrolled in the end. The total positive rate of Juniper chinensis pollen SPT reached 49.92% (4 183/8 380). The positive rate of Juniper chinensis pollen SPT was highest in the 10-14 age group, reaching 60.99% (283/464). Compared with other age groups, there was a statistical difference (χ²=266.77, P<0.01). The SPT positive rate of patients aged less than 10 years increased with the increase of age, while the SPT positive rate of patients aged over 40 years decreased with the increase of age. Single Juniper chinensis pollen was less allergenic, accounting for about 25.05% (1 048/4 183), and the patients' age was (35.21±12.39) years. Regardless of single Juniper chinensis pollen or other pollen allergies, allergic rhinitis was the main disease. Among the patients with SPT positive Juniper chinensis pollen combined with other inhaled pollen allergens, willow pollen accounted for the first (74.99%). The positive rate of Juniper chinensis pollen was the highest in patients with single allergic rhinitis, accounting for 52.05% (3 797/7 295), and the rate in patients with single allergic asthma was the lowest, accounting for 17.49% (53/303), with statistically difference (χ²=138.99, P<0.01). Conclusions: Juniper chinensis pollen is highly sensitized in patients with allergic rhinitis and/or allergic asthma in Beijing . The positive rate of SPT is highest among 10-14 age group, most of which showed strong positive reaction, and allergic rhinitis is more common in Juniper chinensis pollen sensitization diseases.

Abstract
Background The current surveillance system only focuses on notifiable infectious diseases in China. The arrival of the big-data era provides us a chance to elaborate on the full spectrum of infectious diseases. Methods In this population-based observational study, we used multiple health-related data extracted from the Shandong Multi-Center Healthcare Big Data Platform from January 2013 to June 2017 to estimate the incidence density and describe the epidemiological characteristics and dynamics of various infectious diseases in a population of 3,987,573 individuals in Shandong province, China. Results In total, 106,289 cases of 130 infectious diseases were diagnosed among the population, with an incidence density (ID) of 694.86 per 100,000 person-years. Besides 73,801 cases of 35 notifiable infectious diseases, 32,488 cases of 95 non-notifiable infectious diseases were identified. The overall ID continuously increased from 364.81 per 100,000 person-years in 2013 to 1071.80 per 100,000 person-years in 2017 (χ2 test for trend, P < 0.0001). Urban areas had a significantly higher ID than rural areas, with a relative risk of 1.25 (95% CI 1.23–1.27). Adolescents aged 10–19 years had the highest ID of varicella, women aged 20–39 years had significantly higher IDs of syphilis and trichomoniasis, and people aged ≥ 60 years had significantly higher IDs of zoster and viral conjunctivitis (all P < 0.05). Conclusions Infectious diseases remain a substantial public health problem, and non-notifiable diseases should not be neglected. Multi-source-based big data are beneficial to better understand the profile and dynamics of infectious diseases.

Abstract
Studies about the pneumonia morbidity effects of various air pollution exposure are still limited in China. We aimed to explore the short-term effect of air pollutants exposure on pneumonia admission and identify the vulnerable groups in Qingdao, China. From January 2015 to October 2017, a prospective cohort involving 433,032 participants across 3 counties in Qingdao were enrolled in the study. Distributed lag nonlinear model (DLNM) was applied to assess the associations between air pollutants and pneumonia hospitalizations. There were 636 cases of pneumonia, with an annual incidence density of 54.33 per 100,000 person-years (95% CI: 50.11, 58.56). A 10 μg/m3 increment of sulfur dioxide (SO2) distributed at a 4-week lag in Qingdao was associated with increased pneumonia hospitalizations, with a risk ratio of 2.10 (95% CI: 1.06, 4.13). Subgroup analyses indicate that PM ≤ 2.5 μm in aerodynamic diameter and SO2 showed stronger effects on pneumonia in females than males, whereas people in urban regions were more vulnerable to nitrogen dioxide and ozone (O3) than the others. We also observed distinct acute effects and harvesting effects of SO2 and O3 on pneumonia in urban areas. Strategies should be taken to further reduce levels of ambient PM2.5, SO2, and O3.

Abstract
Objective: To investigate the effects of exosomes from human adipose-derived mesenchymal stem cells (ADSCs) on inflammatory response of mouse RAW264.7 cells and wound healing of full-thickness skin defects in mice. Methods: The experimental research methods were adopted. The discarded adipose tissue was collected from 3 female patients (aged 10-25 years) who underwent abdominal surgery in the First Affiliated Hospital of Air Force Medical University. ADSCs were extracted from the adipose tissue by collagenase Ⅰ digestion and identified with flow cytometry. Exosomes were extracted from the human ADSCs by differential ultracentrifugation, the morphology of the exosomes was observed by transmission electron microscopy, the particle diameter of the exosomes was detected by nanoparticle tracking analyzer, and the protein expressions of CD9, CD63, tumor susceptibility gene 101 (TSG101), and β-actin were detected by Western blotting. The human ADSCs exosomes (ADSCs-Exos) and RAW264.7 cells were co-cultured for 12 h, and the uptake of RAW264.7 cells for human ADSCs-Exos was observed. The RAW264.7 cells were divided into phosphate buffer solution (PBS) group stimulated with PBS for suitable time, endotoxin/lipopolysaccharide (LPS) stimulation 2 h group, LPS stimulation 4 h group, LPS stimulation 6 h group, LPS stimulation 12 h group, and LPS stimulation 24 h group stimulated with LPS for corresponding time, with 3 wells in each group, and the mRNA expressions of interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), IL-6, and IL-10 were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-PCR) method. The RAW264.7 cells were divided into PBS group, LPS alone group, and LPS+ADSCs-Exos group, with 3 wells in each group, which were dealt correspondingly for the time screened out in the previous experiment, the mRNA expressions of IL-1β, TNF-α, IL-6, IL-10, trasforming growth factor β (TGF-β,) and vascular endothelial growth factor (VEGF) were detected by real time fluorescence quantitative RT-PCR method, and the protein expressions of inducible nitric oxide synthase (iNOS) and arginase 1 (Arg1) were detected by Western blotting. Twenty-four 8-week-old male BALB/c mice were divided into PBS group and ADSCs-Exos group according to the random number table, with 12 mice in each group, and a full-thickness skin defect wound with area of 1 cm×1 cm was inflicted on the back of each mouse. Immediately after injury, the wounds of mice in the two groups were dealt correspondingly. On post injury day (PID) 1, the concentration of IL-1β and TNF-α in serum were detected by enzyme-linked immunosorbent assay, and the mRNA expressions of IL-1β, TNF-α, and IL-6 were detected by real time fluorescence quantitative RT-PCR method. On PID 3, 6, 9, 12, and 15, the wound healing was observed and the wound non-healing rate was calculated. On PID 15, the defect length of skin accessory and collagen volume fraction (CVF) were detected by hematoxylin eosin staining and Masson staining, respectively, the CD31 expression and neovascularization were detected by immunohistochemistry, and the ratio of Ki67 positive cells, the ratio of iNOS and Arg1 double positive cells, and the ratio of iNOS positive cells to Arg1 positive cells and their fluorescence intensities were detected by immunofluorescence method. The number of samples in animal experiments was 6. Data were statistically analyzed with analysis of variance for repeated measurement, one-way analysis of variance, and independent sample t test. Results: At 12 h of culture, the cells exhibited a typical spindle shape, which were verified as ADSCs with flow cytometry. The exosomes with a vesicular structure and particle diameters of 29-178 nm, were positively expressed CD9, CD63, and TSG101 and negatively expressed β-actin. After 12 h of co-culture, the human ADSCs-Exos were endocytosed into the cytoplasm by RAW264.7 cells. The mRNA expressions of IL-1β, TNF-α, IL-6, and IL-10 of RAW264.7 cells in LPS stimulation 2 h group, LPS stimulation 4 h group, LPS stimulation 6 h group, LPS stimulation 12 h group, and LPS stimulation 24 h group were significantly higher than those in PBS group (with t) values of 39.10, 14.55, 28.80, 4.74, 48.80, 22.97, 13.25, 36.34, 23.12, 18.71, 29.19, 41.08, 11.68, 18.06, 8.54, 43.45, 62.31, 22.52, 21.51, and 37.13, respectively, P<0.01). The stimulation 12 h with significant expressions of all the inflammatory factors was selected as the time point in the following experiment. After stimulation of 12 h, the mRNA expressions of IL-1β, TNF-α, IL-6, and IL-10 of RAW264.7 cells in LPS alone group were significantly higher than those in PBS group (with t values of 44.20, 51.26, 14.71, and 8.54, respectively, P<0.01); the mRNA expressions of IL-1β, TNF-α, and IL-6 of RAW264.7 cells in LPS+ADSCs-Exos group were significantly lower than those in LPS alone group (with t values of 22.89, 25.51, and 8.03, respectively, P<0.01), while the mRNA expressions of IL-10, TGF-β, and VEGF were significantly higher than those in LPS alone group (with t values of 9.89, 13.12, and 7.14, respectively, P<0.01). After stimulation of 12 h, the protein expression of iNOS of RAW264.7 cells in LPS alone group was significantly higher than that in PBS group and LPS+ADSCs-Exos group, respectively (with t values of 11.20 and 5.06, respectively, P<0.05 or P<0.01), and the protein expression of Arg1 was significantly lower than that in LPS+ADSCs-Exos group (t=15.01, P<0.01). On PID 1, the serum concentrations of IL-1β and TNF-α and the mRNA expressions of IL-1β, TNF-α, and IL-6 in wound tissue of mice in ADSCs-Exos group were significantly those in lower than PBS group (with t values of 15.44, 12.24, 9.24, 7.12, and 10.62, respectively, P<0.01). On PID 3, 6, 9, 12, and 15 d, the wound non-healing rates of mice in ADSCs-Exos group were (73.2±4.1)%, (53.8±3.8)%, (42.1±5.1)%, (24.1±2.8)%, and 0, which were significantly lower than (82.5±3.8)%, (71.2±4.6)%, (52.9±4.1)%, (41.5±3.6)%, and (14.8±2.5)% in PBS group, respectively (with t values of 4.77, 8.93, 5.54, 7.63, and 7.59, respectively, P<0.01). On PID 15, the defect length of skin accessory in wounds of mice in PBS group was significantly longer than that in ADSCs-Exos group (t=9.50, P<0.01), and the CVF was significantly lower than that in ADSCs-Exos group (t=9.15, P<0.01). On PID 15, the CD31 expression and the number of new blood vessels (t=12.99, P<0.01), in wound tissue of mice in ADSCs-Exos group were significantly more than those in PBS group, and the ratio of Ki67 positive cells was significantly higher than that in PBS group (t=7.52, P<0.01). On PID 15, the ratio of iNOS and Arg1 double positive cells in wound tissue of mice in PBS group was (12.33±1.97)%, which was significantly higher than (1.78±0.29)% in ADSCs-Exos group (t=13.04, P<0.01), the ratio of iNOS positive cells and the fluorescence intensity of iNOS were obviously higher than those of ADSCs-Exos group, and the ratio of Arg1 positive cells and the fluorescence intensity of Arg1 were obviously lower than those of ADSCs-Exos group. Conclusions: The human ADSCs-Exos can alleviate inflammatory response of mouse RAW264.7 cells, decrease macrophage infiltration and secretion of the pro-inflammatory cytokines, increase the secretion of anti-inflammatory cytokines to promote neovascularization and cell proliferation in full-thickness skin defect wounds of mice, hence accelerating wound healing.

Abstract
Anti-thymocyte globulin (ATG) is often included in the conditioning regimen to prevent graft-versus-host disease (GVHD) in allogeneic hematopoietic cell transplantation (allo-HCT). However, the risk of virus reactivation increases significantly. We conducted a single-center prospective study to identify the optimal ATG exposure that ensures engraftment, effectively prevents acute GVHD, and reduces the risk of virus reactivation without increasing relapse of malignant diseases in haploidentical peripheral blood stem cell transplantation (haplo-PBSCT). From September 2018 to June 2020, 106 patients (median age, 32 years) with malignant hematological diseases who received haplo-PBSCT for the first time were enrolled. All patients received 10 mg/kg rabbit ATG (thymoglobulin) divided for 4 days (days -5 to -2). Pre-transplant, post-transplant, and total areas under the concentration-time curve (AUCs) of active ATG were calculated. Total AUC of active ATG was shown to be the best predictor for virus reactivation and acute GVHD of grades II to IV or grades III and IV. The optimal total AUC range of active ATG was 100 to 148.5 UE/mL/day. The median time was 14 versus 13 days (P = .184) for myeloid engraftment and 13 versus 13 days (P = .263) for platelet engraftment in the optimal and non-optimal AUC groups, respectively. The optimal AUC group showed a lower cumulative incidence of cytomegalovirus (CMV) reactivation and persistent CMV viremia than the non-optimal AUC group: 60.6% (95% confidence interval [CI], 48.3%-73.1%) versus 77.1% (95% CI, 64.5%-87.7%; P = .016) and 31.5% (95% CI, 21.2%-45.3%) versus 56.3% (95% CI, 42.9%-70.4%; P = .007), respectively. The cumulative incidence of persistent Epstein-Barr virus (EBV) viremia in the optimal AUC group was significantly lower than the non-optimal total AUC group: 33.1% (95% CI, 22.5%-46.8%) versus 52.6% (95% CI, 39.3%-67.2%; P = .048). However, there was no difference in EBV reactivation (P = .752). Similar outcomes were observed for grade II to IV and grade III and IV acute GVHD between the two groups: 48.6% (95% CI, 36.8%-62.0%) versus 37.0% (95% CI, 24.8%-52.5%; P = .113) and 10.4% (95% CI, 4.8%-21.7%) versus 4.2% (95% CI, 1.0%-15.6%; P = .234, respectively. Relapse, non-relapse mortality, and disease-free survival demonstrated no significant differences between the two groups. But, overall survival at 2 years tended to increase in the optimal AUC group: 75.7% (95% CI, 62.4%-84.8%) versus 57.8% (95% CI, 42.4%-70.4%; P = .061). These data support an optimal active ATG exposure of 110 to 148.5 UE/mL/day in haplo-PBSCT. Individualized dosing of ATG in allo-HCT might reduce the risk of virus reactivation and effectively prevent acute GVHD simultaneously.

Abstract
Objective: To illuminate the protective effects of pathway in inhibiting ferroptosis by glutathione peroxidase 4 (GPX4) activated by nuclear factor erythroid 2-related factor 2 (Nrf2) during aerobic exercise against myocardial injury in high-fat diet mice. Methods: Forty 5-week-old SPF C57BL/6 male mice were randomly divided into the control group (NC), the exercise group (NE), the high fat group (HC) and the high fat diet with exercise group (HE, began at the same time). There were 10 mice in each group. The mice in the high fat diet group were fed with 60% Kcal SPF high fat model diet. Aerobic exercise was performed using increasing load platform exercise, 5 days /week, 60 min/d, the speed started from 13m/min, and increased by 1m/min every two weeks. Myocardium and blood samples were collected after 14 weeks. Structural changes of myocardial tissues were observed by HE staining. Western blot was used to detect the expressions of Nrf2/GPX4/Ferroptosis related proteins in myocardium. Myocardial peroxide concentration and antioxidant enzyme activity were measured by spectrophotometry. Myocardial mitochondrial 8-hydroxy-2 deoxyguanosine (8-OHdG) and serum insulin were measured by ELISA. Results: Compared with the NC group, there was more lipid accumulation in the myocardial fiber space in the HC group, and the levels of FBG and FINS were increased significantly, while ISI was decreased significantly (P<0.01). Compared with the HC group, the lipid concentration was decreased in the HE group, and the activities of total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD) and glutathione (GSH) were increased significantly, while the levels of mitochondrial 8-OHdG and myocardial iron content were decreased (P<0.01). The expression levels of Ferroportin1 (FPN1), ferritin heavy chain 1 (FTH1), GPX4, glucose transporter (GLUT1) and Nrf2 in the HE group were significantly higher than those in the HC group (P<0.01). Conclusion: The expression of GPX4 was enhanced by more Nrf2 transposition into the nuclear during aerobic exercise, which inhibited the occurrence of myocardial ferroptosis. The activities of antioxidant enzymes were promoted and inhibited the peroxidation damage of myocardial mitochondria.

Abstract
To realize PDE4 inhibitors with good developmental potentiality for the treatment of dementia, structure-based optimizations of lead compound FCPR03 resulted in novel aminophenylketones 9c and 9H with low nanomolar potency, which displayed comparable activity to rolipram, satisfactory bioavailability (F% = 36.92 and 42.96% respectively), and good blood-brain barrier (BBB) permeability switching from the cyclopropyl methoxy group to the cyclopropyl methylamine and the amide group to the corresponding ketone. Emetogenicity evaluation on a combined ketamine/xylazine anesthesia mice alternative model demonstrated that 9H displays no emetogenicity even at an oral dose of 5 mg/kg. In contrast, rolipram and roflumilast displayed emetogenicity at an oral dose of 0.5 mg/kg. In acute toxicological evaluation, 9H showed no obvious toxicological effect on mice when administered at oral doses below 625 mg/kg. Further investigations revealed that 9H improves the memory and cognitive impairment of Alzheimer's disease (AD) model mice induced by Aβ25-35.

Abstract
Background The health of the elderly is one of the major challenges in today's ageing society. However, research on infectious diseases among the elderly is limited. This study aimed to describe the epidemiological characteristics and dynamics of infectious diseases among the elderly population aged ≥60 years in Shandong province, China. Methods Incidence data for infectious diseases were collected from the Shandong Multi-Center Healthcare Big Data Platform from January 2013 to June 2017, which involved 550 432 elderly persons. We compared the incidence of each infectious disease and disease category, stratified by age, gender, and region. Annual percentage change (APC) was estimated using logarithmic linear regression to examine the incidence trends. Poisson regression was conducted to identify the effect of demographic factors on incidence, with incidence rate ratio (IRR) and their 95% confidence intervals (CIs) estimated. Results A total of 27 595 cases of 102 infectious diseases were reported during the study period, with an overall incidence of 1425.51/100 000 person-years. The most common infectious diseases were respiratory and mucocutaneous diseases among the elderly persons, with annual increases of 17.45% and 20.44%, respectively (both P<0.05). In rural areas, the incidence of respiratory, gastrointestinal, blood- and sex-transmitted, and mucocutaneous infections increased significantly, with APCs of 178.52%, 204.66%, 28.24%, 63.01%, respectively (all P<0.05). Elderly males had a higher risk of infections than that of females, with the highest IRRa of 2.94 (95% confidence interval (CI) = 2.89, 3.00) in respiratory diseases. The elderly aged 85-89 years had a much higher risk of respiratory diseases than those aged 60-64 years (IRRa = 9.85, 95%CI: 9.39, 10.33); however, the risk of blood- and sex-transmitted diseases was highest among the elderly aged 65-69 years (IRRa = 1.24, 95% CI = 1.06, 1.45). Conclusions Ageing population are facing a substantial challenge on infectious diseases. More attention should be paid to infections with significant growth. Targeted strategies and measures on elderly persons in different regions and subgroups are urgently needed.

Abstract
Background Neuroinflammation and mitochondrial impairment play important roles in the neuropathogenesis of Parkinson’s disease (PD). The activation of NLRP3 inflammasome and the accumulation of α-synuclein (α-Syn) are strictly correlated to neuroinflammation. Therefore, the regulation of NLRP3 inflammasome activation and α-Syn aggregation might have therapeutic potential. It has been indicated that Dl-3-n-butylphthalide (NBP) produces neuroprotection against some neurological diseases such as ischemic stroke. We here intended to explore whether NBP suppressed NLRP3 inflammasome activation and reduced α-Syn aggregation, thus protecting dopaminergic neurons against neuroinflammation. Methods In our study, we established a MPTP-induced mouse model and 6-OHDA-induced SH-SY5Y cell model to examine the neuroprotective actions of NBP. We then performed behavioral tests to examine motor dysfunction in MPTP-exposed mice after NBP treatment. Western blotting, immunofluorescence staining, flow cytometry and RT-qPCR were conducted to investigate the expression of NLRP3 inflammasomes, neuroinflammatory cytokines, PARP1, p-α-Syn, and markers of microgliosis and astrogliosis. Results The results showed that NBP exerts a neuroprotective effect on experimental PD models. In vivo, NBP ameliorated behavioral impairments and reduced dopaminergic neuron loss in MPTP-induced mice. In vitro, treatment of SH-SY5Y cells with 6-OHDA (100uM,24 h) significantly decreased cell viability, increased intracellular ROS production, and induced apoptosis, while pretreatment with 5uM NBP could alleviated 6-OHDA-induced cytotoxicity, ROS production and cell apoptosis to some extent. Importantly, both in vivo and in vitro, NBP suppressed the activation of the NLRP3 inflammasome and the aggregation of α-Syn, thus inhibited neuroinflammation ameliorated mitochondrial impairments. Conclusions In summary, NBP rescued dopaminergic neurons by reducing NLRP3 inflammasome activation and ameliorating mitochondrial impairments and increases in p-α-Syn levels. This current study may provide novel neuroprotective mechanisms of NBP as a potential therapeutic agent.

Abstract
We have previously shown that roflupram (ROF) protects against MPP+-induced neuronal damage in models of Parkinson's disease (PD). Since impaired degradation of α-synuclein (α-syn) is one of the key factors that lead to PD, here we investigated whether and how ROF affects the degradation of α-syn in rotenone (ROT)-induced PD models in vivo and in vitro. We showed that pretreatment with ROF (10 μM) significantly attenuated cell apoptosis and reduced the level of α-syn in ROT-treated SH-SY5Y cells. Furthermore, ROF significantly enhanced the lysosomal function, as evidenced by the increased levels of mature cathepsin D (CTSD) and lysosomal-associated membrane protein 1 (LAMP1) through increasing NAD+/NADH and the expression of sirtuin 1 (SIRT1). Pretreatment with an SIRT1 inhibitor selisistat (SELI, 10 μM) attenuated the neuroprotection of ROF, ROF-reduced expression of α-syn, and ROF-increased expression levels of LAMP1 and mature CTSD. Moreover, inhibition of CTSD by pepstatin A (20 μM) attenuated ROF-reduced expression of α-syn. In vivo study was conducted in mice exposed to ROT (10 mg·kg-1·d-1, i.g.) for 6 weeks; then, ROT-treated mice received ROF (0.5, 1, or 2 mg·kg-1·d-1; i.g.) for four weeks. ROF significantly ameliorated motor deficits, which was accompanied by increased expression levels of tyrosine hydroxylase, SIRT1, mature CTSD, and LAMP1, and a reduced level of α-syn in the substantia nigra pars compacta. Taken together, these results demonstrate that ROF exerts a neuroprotective action and reduces the α-syn level in PD models. The mechanisms underlying ROF neuroprotective effects appear to be associated with NAD+/SIRT1-dependent activation of lysosomal function.

Abstract
Charge mobility is an essential factor of organic crystalline materials. Although many investigators have made important progress, the exact relationship between the crystal structure and carrier mobility remains to be clarified. Fortunately, a series of bis-1,3,4-oxadiazole derivatives have been successfully prepared and reported. They have similar main molecular fragments but different crystal packing modes, which provide an ideal research objective for studying the effect of molecular packing on charge mobility in organic photoelectric conversion systems. In this work, the charge mobilities of these molecules are systematically evaluated from the perspective of first-principles calculation, and the effect of a molecular overlap on orbital overlap integral and final charge carrier mobility is fully discussed. It can be seen that the small intermolecular distance (less than 6 Å) is the decisive factor to achieve high electron mobility in π stacking, and better mobility can be obtained by increasing the hole migration distance appropriately. A larger dihedral angle of anisotropy is an important point limiting the charge mobility in the herringbone arrangement. It is hoped that the correlation results between the crystal structure and mobility can assist the experimental study and provide an effective way to improve the photoelectric conversion efficiency of the organic semiconductor devices and multiple basis for multiscale material system characterization and material information.

Abstract
Background The objective of this study was to construct a risk classification system integrating cell-free Epstein-Barr virus (cfEBV) DNA with T- and N- categories for better prognostication in nasopharyngeal carcinoma (NPC). Methods Clinical records of 10,149 biopsy-proven, non-metastatic NPC were identified from two cancer centers; this comprised a training (N = 9,259) and two validation cohorts (N = 890; including one randomized controlled phase 3 trial cohort). Adjusted hazard ratio (AHR) method using a two-tiered stratification by cfEBV DNA and TN-categories was applied to generate the risk model. Primary clinical endpoint was overall survival (OS). Performances of the models were compared against American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) 8th edition TNM-stage classification and two published recursive partitioning analysis (RPA) models, and were validated in the validation cohorts. Results We chose a cfEBV DNA cutoff of ⩾2,000 copies for optimal risk discretization of OS, disease-free survival (DFS) and distant metastasis-free survival (DMFS) in the training cohort. AHR modeling method divided NPC into six risk groups with significantly disparate survival (p < 0.001 for all): AHR1, T1N0; AHR2A, T1N1/T2-3N0 cfEBV DNA < 2,000 (EBVlow); AHR2B, T1N1/T2-3N0 cfEBV DNA ⩾ 2,000 (EBVhigh) and T1-2N2/T2-3N1 EBVlow; AHR3, T1-2N2/T2-3N1 EBVhigh and T3N2/T4N0 EBVlow; AHR4, T3N2/T4 N0-1 EBVhigh and T1-3N3/T4N1-3 EBVlow; AHR5, T1-3N3/T4 N2-3 EBVhigh. Our AHR model outperformed the published RPA models and TNM stage with better hazard consistency (1.35 versus 3.98-12.67), hazard discrimination (5.29 versus 6.69-13.35), explained variation (0.248 versus 0.164-0.225), balance (0.385 versus 0.438-0.749) and C-index (0.707 versus 0.662-0.700). In addition, our AHR model was superior to the TNM stage for risk stratification of OS in two validation cohorts (p < 0.001 for both). Conclusion Herein, we developed and validated a risk classification system that combines the AJCC/UICC 8th edition TN-stage classification and cfEBV DNA for non-metastatic NPC. Our new clinicomolecular model provides improved OS prediction over the current staging system.

Abstract
A Gram-stain-positive, strictly aerobic, motile, endospore-forming, milk-white, indole acetic acid-producing, rod-shaped bacterial strain, designated as HU2P27T, was isolated from a shoot of Kalidium cuspidatum collected in Tumd Right Banner, Inner Mongolia, PR China. Strain grew at 10-40 °C (optimum, 30 °C), at pH 6.0-9.0 (optimum, pH 7.0) and with 0-14.0 % NaCl (optimum, 5.0-8.0 %). The strain tested positive for oxidase, catalase and nitrate reductase. The phylogenetic trees based on the 16S rRNA gene sequence and the core genome both showed that strain HU2P27T clustered with Aquibacillus koreensis BH30097T, sharing 97.7 % and <97.0 % of 16S rRNA gene similarity with A. koreensis BH30097T and any other type strain. Strain HU2P27T contained MK-7 as the major respiratory quinone. Its major fatty acids were anteiso-C15 : 0 and iso-C15 : 0, and the major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and four unidentified phospholipids. The genomic DNA G+C content was 36.0 mol%. The average nucleotide identity, amino acid identity and digital DNA-DNA hybridization values of strain HU2P27T with A. koreensis BH30097T were 71.7, 69.2 and 19.4%, respectively. The phylogenetic, physiological and phenotypic results allowed the discrimination of strain HU2P27T from its phylogenetic relatives. The name Aquibacillus kalidii sp. nov. is therefore proposed. The type strain is strain HU2P27T (=CGMCC 1.18646T=KCTC 43248T). Based on the results of 16S rRNA gene and genome analyses, we propose the reclassification of Virgibacillus campisalis Lee et al. 2012 as a later heterotypic synonym of Virgibacillus alimentarius Kim et al. 2011.

Abstract
To analyze the sensitization characteristics and significance of airborne allergens in chronic urticaria (CU) with airway allergic diseases (allergic rhinitis and/or asthma). From May to August 2015, the Department of allergy, Beijing Shijitan Hospital Affiliated to Capital Medical University conducted an epidemiological survey of allergic diseases in grassland area of Inner Mongolia by multistage stratified cluster sampling. The results of skin prick test (SPT) for airborne allergens in 191 patients with CU and 1 132 patients with airway allergic diseases were analyzed. The statistical data were tested by chi-square segmentation method, and the stratified trend of rate was tested by Linear-by-Linear. Among the 191 patients with CU, 92 (48.17%) had CU without airway allergic diseases (CU alone), and 99 (51.83%) had CU with airway allergic diseases. The top three air allergens were house dust mite, chenopodium pollen and salix pollen in CU alone (only one is the major local allergen), and artemisia, humulus scandens and chenopodium pollen in CU with airway allergic diseases (All are the main local allergens) and airway allergic diseases. Compared between CU alone and CU with airway allergic disease, the positive rate of allergen SPT and multiple strong positive rate were statistically significant (59.60% vs 38.04%, χ²=13.336;27.12% vs 2.86%, χ²=8.729;P<0.016 7).There was no significant difference in positive rate of skin prick, multiple positive rate, strong positive rate and multiple strong positive rate between CU with airway allergic disease and airway allergic diseases (59.60% vs 57.69%, χ²=0.136, P>0.016 7; 71.19% vs 75.20%, χ²=0.461, P>0.016 7; 54.24% vs 69.68%, χ²=5.969, P>0.016 7; 27.12% vs 37.83%, χ²=2.663, P>0.016 7), but there was significant difference in these between CU without airway allergic disease and airway allergic diseases (38.04% vs 57.69%, χ²=13.336, P<0.01; 51.43% vs 75.20%, χ²=9.745, P<0.01; 28.57% vs 69.68%, χ²=25.624, P<0.01; 2.86% vs 37.83%, χ²=17.620, P<0.01).The strong positive rate and the multiple strong positive rate of allergen increased with the increase of CU with allergic diseases, and the trend difference was statistically significant (38.04%,56.98% and 76.92%, χ²=10.601, P<0.01; 28.57%,46.94% and 90.00%, χ²=12.085, P<0.01; 2.86%,24.49% and 40.00%, χ²=10.077, P<0.01). The allergen sensitization characteristics of CU with airway allergic diseases are similar to airway allergic diseases,and the detection of airborne allergens may have certain clinical value in the screening of risk factors for patients with CU associated with airway allergic diseases.

Abstract
Sepsis remains a leading cause of death in critical patients. Both excessive inflammatory response and long-term immunosuppression can lead to the death of sepsis patients. As a key pro-inflammatory cytokine, interleukin-17 (IL-17) plays an important role in the body's inflammatory response and immune system. The signal transduction of IL-17 is a key link in maintaining the body's health and participating in the onset and development of sepsis. This review mainly summarizes and discusses the regulation of IL-17 signal transduction and pathogenic and protective role of IL-17 in sepsis.

Abstract
Genetic modification technologies can be used for modifying animal genome to express exogenous genes or affect the function of endogenous genes. In animal breeding, genetic modification technologies allow the rapid generation of germplasms with beneficial traits. It includes traditional genetic modification, virus or sperm carrier-mediated genetic modification and nuclease-mediated genome editing, especially the CRISPR/Cas9, one of the artificial nuclease genome editing technologies, have been applied in genome editing in many domestic animals including sheep (Ovis aries). Compared with conventional strategies used for animal breeding, there is great value for sheep breeding improvement by using genome editing technology, which is more effective and timesaving. In this review, we summarize the approaches of genetic modification in sheep and discuss the possibility of molecular design and breeding of sheep by genome editing technologies. We also identify the potential bottlenecks and challenges of these technologies in sheep breeding.

Abstract
To discover PDE4/tubulin dual inhibitors with novel skeleton structures, 7-trimethoxyphenylbenzo[d]oxazoles 4a-u and 4-trimethoxyphenylbenzo[d]oxazoles 5a-h were designed and synthesized by migrating the trimethoxyphenyl group of TH03 to the benzo[d]oxazole moiety. Among these compounds, approximately half of them displayed good antiproliferative activities against glioma (U251) and lung cancer (A549 and H460) cell lines. The structure-activity relationships of trimethoxyphenylbenzo[d]oxazoles led to the identification of 4r bearing indol-5-yl side-chain as a novel dual PDE4/tubulin inhibitor, which exhibited satisfactory antiproliferative activities against glioma (IC50 = 300 ± 50 nM) and lung cancer (average IC50 = 39.5 nM) cells. Further investigations revealed that 4r induced apoptosis at G2/M phase arrest and disrupted the microtubule network. The preliminary mechanism of action showed that 4r down-regulated the expression of cyclin B1 and its upstream regulator gene cdc25C in A549.

Abstract
Objective: To understand the time for observation and related factors in the clinics after vaccination among children's parents. Methods: From December 2019 to January 2020, parents of children aged 0-3 years were recruited by multiple-stage sampling from 34 vaccination clinics in 12 districts and counties in 6 provinces (Shandong, Guangdong, Henan, Sichuan, Inner Mongolia, and Liaoning). A questionnaire survey on the time of observation after vaccination was conducted. A multivariate logistic regression model was used to analyze the related factors of parental observation time after vaccination. Results: A total of 3 292 parents of 0-3 year's old children were selected, and 3 178 parents were finally included in the analysis. 87.85%(2 792/3 178) of the parents reported that the observation time after vaccination at clinics was ≥30 minutes. Multivariate logistic regression analysis showed that, after adjusting for the regions, the main factors affecting the observation time at clinics after vaccination among parents appeared as observation time informed by physicians at the clinic appeared ≥30 minutes (OR=31.622, 95%CI: 19.847-50.384), parents were medical personnel (OR=2.779, 95%CI: 1.505-5.133), parents being volunteers working on vaccination-related publicity and education activities (OR=1.986, 95%CI: 1.438-2.743), parents aged 35 years old or above (OR=1.900, 95%CI: 1.215-2.971), being parents of the first child (OR=1.663, 95%CI: 1.282-2.156), per capita annual income of the family as 8 000- Yuan (OR=1.646, 95%CI: 1.168-2.319), children aged 0-12 months old (OR=1.646, 95%CI: 1.203-2.252) or 13-24 months old (OR=1.506, 95%CI: 1.064-2.133), obedient to physicians' advice at the clinic (OR=1.481, 95%CI: 1.067-2.055). Conclusions: The proportions of parents observed for ≥30 minutes at the clinics of vaccination were high. When the information was from the physicians at the vaccination clinic, the observation time was the most critical factor for parents to observe at clinics as required.

Abstract
Hypertrophic scars and keloids are common sequelae after wound healing, with a high incidence, which seriously affect the patient's quality of life. However, there is still a lack of effective prevention and treatment methods, mainly because the pathogenesis of scars is not clear. Current research believe that inflammatory response plays a critical role in the process of scar formation, and through the researches on the mechanisms it is hopeful to find new potential therapeutic drug targets for the prevention and treatment of hypertrophic scars and keloids. This article mainly reviews the research progresses on the role and mechanism of inflammatory cytokines and inflammatory cells in the formation of hypertrophic scars and keloids, as well as drugs, microRNAs, and exosomes, etc., for the treatment of hypertrophic scars and keloids by inhibiting inflammatory response.
