Abstract
2-Methyl-1-butanol (2MB) and 3-Methyl-1-butanol (3MB) are microbial volatile organic compounds (VOCs) and found in indoor air. Here, we applied rice as a bioindicator to investigate the effects of these indoor microbial volatile pollutants. A remarkable decrease in germination percentage, shoot and root elongation, as well as lateral root numbers were observed in 3MB. Furthermore, ROS production increased by 2MB and 3MB, suggesting that pentanol isomers could induce cytotoxicity in rice seedlings. The enhancement of peroxidase (POD) and catalase (CAT) activity provided evidence that pentanol isomers activated the enzymatic antioxidant scavenging systems, with a more significant effect observed in 3MB. Furthermore, 3MB induced higher activity levels of glutathione (GSH), oxidized glutathione (GSSG), and the GSH/GSSG ratio in rice compared to the levels induced by 2MB. Additionally, qRT-PCR analysis showed more up-regulation in the expression of glutaredoxins (GRXs), peroxiredoxins (PRXs), thioredoxins (TRXs), and glutathione S-transferases (GSTUs) genes in 3MB. Taking the impacts of pentanol isomers together, the present study suggests that 3MB exhibits more cytotoxic than 2MB, as such has critical effects on germination and the early seedling stage of rice. Our results provide molecular insights into how isomeric indoor microbial volatile pollutants affect plant growth through airborne signals.

Abstract
Previous studies on the intricate interactions between plants and microorganisms have revealed that fungal volatile compounds (VCs) can affect plant growth and development. However, the precise mechanisms underlying these actions remain to be delineated. In this study, we discovered that VCs from the soilborne fungus Tolypocladium inflatum GT22 enhance the growth of Arabidopsis. Remarkably, priming Arabidopsis with GT22 VCs caused the plant to display an enhanced immune response and mitigated the detrimental effects of both pathogenic infections and copper stress. Transcriptomic analyses of Arabidopsis seedlings treated with GT22 VCs for 3, 24 and 48 h revealed that 90, 83 and 137 genes were differentially expressed, respectively. The responsive genes are known to be involved in growth, hormone regulation, defense mechanisms and signaling pathways. Furthermore, we observed the induction of genes related to innate immunity, hypoxia, salicylic acid biosynthesis and camalexin biosynthesis by GT22 VCs. Among the VCs emitted by GT22, exposure of Arabidopsis seedlings to limonene promoted plant growth and attenuated copper stress. Thus, limonene appears to be a key mediator of the interaction between GT22 and plants. Overall, our findings provide evidence that fungal VCs can promote plant growth and enhance both biotic and abiotic tolerance. As such, our study suggests that exposure of seedlings to T. inflatum GT22 VCs may be a means of improving crop productivity. This study describes a beneficial interaction between T. inflatun GT22 and Arabidopsis. Our investigation of microorganism function in terms of VC activities allowed us to overcome the limitations of traditional microbial application methods. The importance of this study lies in the discovery of T. inflatun GT22 as a beneficial microorganism. This soilborne fungus emits VCs with plant growth-promoting effects and the ability to alleviate both copper and pathogenic stress. Furthermore, our study offers a valuable approach to tracking the activities of fungal VC components via transcriptomic analysis and sheds light on the mechanisms through which VCs promote plant growth and induce resistance. This research significantly advances our knowledge of VC applications and provides an example for further investigations within this field.

Abstract
Indoor air pollution is a global problem and one of the main stress factors that has negative effects on plant and human health. 3-methyl-1-butanol (3MB), an indoor air pollutant, is a microbial volatile organic compound (mVOC) commonly found in damp indoor dwellings. In this study, we reported that 1 mg/L of 3MB can elicit a significant reduction in the stomatal aperture ratio in Arabidopsis and tobacco. Our results also showed that 3MB enhances the reactive oxygen species (ROS) production in guard cells of wild-type Arabidopsis after 24 h exposure. Further investigation of 24 h 3MB fumigation of rbohD, the1-1, mkk1, mkk3, and nced3 mutants revealed that ROS production, cell wall integrity, MAPK kinases cascade, and phytohormone abscisic acid are all involved in the process of 3MB-induced stomatal. Our findings proposed a mechanism by which 3MB regulates stomatal closure in Arabidopsis. Understanding the mechanisms by which microbial indoor air pollutant induces stomatal closure is critical for modulating the intake of harmful gases from indoor environments into leaves. Investigations into how stomata respond to the indoor mVOC 3MB will shed light on the plant's "self-defense" system responding to indoor air pollution.

Abstract
Objective: To investigate the clinicopathological characteristics of primary pulmonary NUT carcinoma. Methods: A total of 7 cases of primary pulmonary NUT carcinoma were collected from Fujian Provincial Hospital (n=5), Fuzhou Taijiang Hospital (n=1) and Binzhou City People's Hospital of Shandong Province (n=1) from January 2021 to April 2023. The clinical, histopathological, and immunohistochemical features were analyzed, and NUT rearrangement were detected by fluorescence in situ hybridization (FISH) with break-apart probes. Results: Seven cases were all male with age ranging from 32 to 73 years. The main clinical manifestations were cough, expectoration and chest tightness. Microscopically, NUT carcinoma was composed of monotonous proliferation of primitive-appearing small-to-medium round cells, with few eosinophilic cytoplasm, arranged in solid sheets, nests or clusters. Abrupt keratinization was typically observed in 4 cases (4/7), with high mitotic activities and necrosis. Immunohistochemistry (IHC) showed that the tumors were positive for NUT (7/7), CK7 (4/4), CK5/6 (5/6), p40 (6/7). Ki-67 index were 30%-80%. NUT gene segregation (7/7) was detected by FISH break probes. Conclusions: Primary pulmonary NUT carcinoma is rare and highly malignant. Diagnosis depends on histopathology and IHC, with molecular detection as an adjunct for diagnosis. Pathologists should be aware of the clinicopathological characteristics to avoid misdiagnosis.

Abstract
Microbial volatile compounds (mVCs) may cause stomatal closure to limit pathogen invasion as part of plant innate immune response. However, the mechanisms of mVC-induced stomatal closure remain unclear. In this study, we co-cultured Enterobacter aerogenes with Arabidopsis (Arabidopsis thaliana) seedlings without direct contact to initiate stomatal closure. Experiments using the reactive oxygen species (ROS)-sensitive fluorescent dye, H2DCF-DA, showed that mVCs from E. aerogenes enhanced ROS production in guard cells of wild-type plants. The involvement of ROS in stomatal closure was then demonstrated in an ROS production mutant (rbohD). In addition, we identified two stages of signal transduction during E. aerogenes VC-induced stomatal closure by comparing the response of wild-type Arabidopsis with a panel of mutants. In the early stage (3 h exposure), E. aerogenes VCs induced stomatal closure in wild-type and receptor-like kinase THESEUS1 mutant (the1-1) but not in rbohD, plant hormone-related mutants (nced3, erf4, jar1-1), or MAPK kinase mutants (mkk1 and mkk3). However, in the late stage (24 h exposure), E. aerogenes VCs induced stomatal closure in wild-type and rbohD but not in nced3, erf4, jar1-1, the1-1, mkk1 or mkk3. Taken together, our results suggest that E. aerogenes mVC-induced plant immune responses modulate stomatal closure in Arabidopsis by a multi-phase mechanism.

Abstract
Increasing evidence suggests that in disease-suppressive soils, microbial volatile compounds (mVCs) released from bacteria may inhibit the growth of plant-pathogenic fungi. However, the antifungal activities and molecular responses of fungi to different mVCs remain largely undescribed. In this study, we first evaluated the responses of pathogenic fungi to treatment with mVCs from Paenarthrobacter ureafaciens. Then, we utilized the well-characterized fungal model organism Saccharomyces cerevisiae to study the potential mechanistic effects of the mVCs. Our data showed that exposure to P. ureafaciens mVCs leads to reduced growth of several pathogenic fungi, and in yeast cells, mVC exposure prompts the accumulation of reactive oxygen species. Further experiments with S. cerevisiae deletion mutants indicated that Slt2/Mpk1 and Hog1 MAPKs play major roles in the yeast response to P. ureafaciens mVCs. Transcriptomic analysis revealed that exposure to mVCs was associated with 1,030 differentially expressed genes (DEGs) in yeast. According to gene ontology and Kyoto Encyclopedia of Genes and Genomes analyses, many of these DEGs are involved in mitochondrial dysfunction, cell integrity, mitophagy, cellular metabolism, and iron uptake. Genes encoding antimicrobial proteins were also significantly altered in the yeast after exposure to mVCs. These findings suggest that oxidative damage and mitochondrial dysfunction are major contributors to the fungal toxicity of mVCs. Furthermore, our data showed that cell wall, antioxidant, and antimicrobial defenses are induced in yeast exposed to mVCs. Thus, our findings expand upon previous research by delineating the transcriptional responses of the fungal model. IMPORTANCE Since the use of bacteria-emitted volatile compounds in phytopathogen control is of considerable interest, it is important to understand the molecular mechanisms by which fungi may adapt to microbial volatile compounds (mVCs). Paenarthrobacter ureafaciens is an isolated bacterium from disease-suppressive soil that belongs to the Actinomycetota phylum. P. ureafaciens mVCs showed a potent antifungal effect on phytopathogens, which may contribute to disease suppression in soil. However, our knowledge about the antifungal mechanism of mVCs is limited. This study has proven that mVCs are toxic to fungi due to oxidative stress and mitochondrial dysfunction. To deal with mVC toxicity, antioxidants and physical defenses are required. Furthermore, iron uptake and CAP proteins are required for antimicrobial defense, which is necessary for fungi to deal with the thread from mVCs. This study provides essential foundational knowledge regarding the molecular responses of fungi to inhibitory mVCs.

Abstract
PURPOSE/OBJECTIVE(S) To improve the accuracy of superficial dose coverage for patients undergoing modified radical mastectomy (MRM), boluses are frequently applied to the skin surface of targeted region during radiotherapy. The irregular curvature of MRM breast cases results in discrepancies of dosimetry and poor contact. Additionally, the presence of an air gap causes unnecessary high-dose escalation and uncertainty in dose calculation, making the use of commercial flat bolus problematic. This study evaluated the effectiveness of 3D-printed bolus by comparing it to commercial bolus in setup variations and dosimetric compliance through daily cone-beam computed tomography (CBCT) scans. MATERIALS/METHODS Ten patients underwent MRM were divided into 2 groups. 5 patients treated with 0.5 cm commercial bolus as group A while the other 5 patients covered by 3D Bolus as group B. 3D bolus was made of polylactic acid filament (PLA) and contoured in advance with thickness of 0.5 cm on the surface of target. Positional errors were recorded through daily image guidance and compared with the images. Both groups had right-sided breast with neck lymph nodes involved and received 50 Gy in 25 fractions using 4 partial arcs of the volumetric modulated arc therapy (VMAT) technique. The CBCTs were recalculated through treatment planning system (TPS) to assess superficial dose coverage. A two-tailed student's t-test was applied. RESULTS Groups A and B pitch angles were -0.203 ± 0.837° and 0.334 ± 0.909° (p = 0.0003). Roll angle were 0.313 ± 0.728° and -0.633 ± 1.286° (p = 0.0000013). Yaw angle were -0.034 ± 0.872° and 0.018 ± 0.883° (p = 0.721). There was a trend of differences in the Z-axis and significant statistical differences in the pitch and roll angles due to aligning gel layers directly with group A's body surface, while 3D bolus rigidly adherence to group B's delineated curve. In the planned target volume (PTV), the CI and HI of group A were 0.9448±0.0208 and 1.2061±0.0448, respectively, while 0.9776±0.0144 and 1.1472±0.0206 (p<0.005) were for group B. As for the superficial region, which is defined from body surface to 0.5cm inside PTV, CI and HI of A were 0.8290±0.0599 and 1.4675±0.2434, while for B, they were 0.9753±0.0214 and 1.1330±0.0126, respectively (p<0.005). CONCLUSION The study analyzed the results through image comparison and investigated the CI and HI between two types of boluses. The 3D bolus reduces setup errors and improves dose coverage especially when superficial region is concerned. Better consistency of patient repositioning and dosimetry can be achieved and proved by daily assessment of CBCT scan. The customization of 3D bolus with integration of TPS and CT scans provides a solution to the inadequacies of commercial bolus. The results suggest that the use of 3D bolus is a promising development in radiation therapy for MRM breast cancer patients.

Abstract
Cinnamaldehyde (CA) is a volatile plant secondary metabolite that exhibits strong anti-pathogenic activities. Nonetheless, less is known about the effect of CA on plant tolerance to abiotic stresses. In this study, we delineated the effects of CA fumigation on rice roots (Oryza Sativa L cv. TNG67) under salinity stress (200 mM NaCl). Our result showed that CA vapour significantly alleviated salinity-induced ROS accumulation and cell death. This CA-induced alleviation appears to be mediated primarily by the upregulation of proline metabolism genes, the rapid proline accumulation, and the decrease of Na+ /K+ ratio as early as 3 h after NaCl treatment. Of note, the activities of peroxidase (POD; EC 1.11.1.7) isozymes a and b were decreased by CA fumigation, and the activities of catalase (CAT; EC 1.11.1.6) and superoxide dismutase (SOD; EC 1.15.1.1) were not significantly affected. Our findings suggest that CA vapour might be useful for priming rice roots to withstand salinity stress, which is more prevalent due to the ongoing global climate change. To the best of our knowledge, this is the first study to show modulation of macro- and micro-elements as well as antioxidative factors after CA fumigation of salinity-stressed rice roots.

Abstract
Plant-deleterious microbial volatiles activate the transactivation of hypoxia, MAMPs and wound responsive genes in Arabidopsis thaliana. AtMKK1 and AtMKK3 are involved in the plant-deleterious microbial volatiles-induced defense responses. Microbial volatile compounds (mVCs) are a collection of volatile metabolites from microorganisms with biological effects on all living organisms. mVCs function as gaseous modulators of plant growth and plant health. In this study, the defense events induced by plant-deleterious mVCs were investigated. Enterobacter aerogenes VCs lead to growth inhibition and immune responses in Arabidopsis thaliana. E. aerogenes VCs negatively regulate auxin response and transport gene expression in the root tip, as evidenced by decreased expression of DR5::GFP, PIN3::PIN3-GFP and PIN4::PIN4-GFP. Data from transcriptional analysis suggests that E. aerogenes VCs trigger hypoxia response, innate immune responses and metabolic processes. In addition, the transcript levels of the genes involved in the synthetic pathways of antimicrobial metabolites camalexin and coumarin are increased after the E. aerogenes VCs exposure. Moreover, we demonstrate that MKK1 serves as a regulator of camalexin biosynthesis gene expression in response to E. aerogenes VCs, while MKK3 is the regulator of coumarin biosynthesis gene expression. Additionally, MKK1 and MKK3 mediate the E. aerogenes VCs-induced callose deposition. Collectively, these studies provide molecular insights into immune responses by plant-deleterious mVCs.

Abstract
Objective: To investigate the clinicopathologic and molecular genetic characteristics of myxoid pleomorphic liposarcoma (MPLPS). Methods: Six cases of MPLPS diagnosed and consulted in Fujian Provincial Hospital from 2015 to 2021 were collected for histomorphological observation, immunohistochemistry, and fluorescence in situ hybridization (FISH) detection of DDIT3 (CHOP) gene translocation and MDM2/CDK4 gene amplification. Results: There were four males and two females, aged 26-74 years (mean 53.8 years). The tumor size was 3.8-16.0 cm (mean 11.8 cm). All six cases had similar histopathologic features, showing overlapping histologic morphology of myxoid liposarcoma and pleomorphic liposarcoma. Four cases (4/6) were positive for S-100 protein, and the Ki-67 index was 50%-95%. All cases (6/6) were negative for DDIT3 (CHOP) translocation and MDM2/CDK4 amplification by FISH. TP53 (p.R248w) germline mutation was found in one case. Conclusions: MPLPS is a rare subtype of liposarcoma, characterized by overlapping morphology of myxoid liposarcoma and pleomorphic liposarcoma. Genetically, a few of them have TP53 gene germline mutations, but they lack of DDIT3 (CHOP) translocation or MDM2/CDK4 amplification.

Abstract
Background Implementation of adjuvant therapies in non-metastatic melanoma improved treatment outcomes in some patients; however, adjuvant therapy can be associated with significant cost and risk of toxicity. Therefore, there is an unmet need to better identify patients at high risk of recurrence. Patients and methods We carried out an ultrasensitive droplet digital PCR (ddPCR)-based detection of BRAFV600E-mutated circulating tumor DNA (ctDNA) from blood samples prospectively collected before surgery, 1 hour after surgery, and then serially during follow-up. Results In 80 patients (stages ≤III), BRAFV600E mutations were detected in 47.2% of tissue, in 37.7% of ctDNA samples collected before surgery, and in 25.9% of ctDNA samples collected 1 hour after surgery. Patients with detected ctDNA in blood collected 1 hour after surgery compared to patients without detected ctDNA had higher likelihood of melanoma recurrence (P < 0.001) and shorter median disease-free survival (P = 0.001) and overall survival (P = 0.003). Conclusions Ultrasensitive ddPCR can detect ctDNA in pre- and post-surgical blood samples from patients with resectable melanoma. Detection of ctDNA in post-surgical samples is associated with inferior treatment outcomes. Ultrasensitive ddPCR can detect ctDNA in pre- and post-surgical samples. Detection of ctDNA 1 hour after surgery is associated with inferior treatment outcomes. There were no associations between ctDNA detection at other timepoints and clinical outcomes.

Abstract
Transcription activator-like effector nuclease (TALEN) technology has been widely used to edit nuclear genomes in plants but rarely for editing organellar genomes. In addition, ciprofloxacin, commonly used to cause the double-strand break of organellar DNA for studying the repair mechanism in plants, confers no organellar selectivity and site-specificity. To demonstrate the feasibility of TALEN-mediated chloroplast DNA editing and to use it for studying the repair mechanism in plastids, we developed a TALEN-mediated editing technology fused with chloroplast transit peptide (cpTALEN) to site-specifically edit the rpoB gene via Agrobacteria-mediated transformation of tobacco leaf. Transgenic plants showed various degrees of chlorotic phenotype. Repairing damaged plastid DNA resulted in point mutation, large deletion and small inversion surrounding the rpoB gene by homologous recombination and/or microhomology-mediated recombination. In an albino line, microhomology-mediated recombination via a pair of 12-bp direct repeats between rpoC2 and ycf2 genes generated the chimeric ycf2-rpoC2 subgenome, with the level about 3- to 5-fold higher for subgenomic DNA than ycf2. Additionally, the expression of chimeric ycf2-rpoC2 transcripts versus ycf2 mRNA agreed well with the level of corresponding DNA. The ycf2-rpoC2 subgenomic DNA might independently and preferentially replicate in plastids.

Abstract
Background Oncogenic mutations in PIK3CA are prevalent in diverse cancers and can be targeted with inhibitors of the phosphoinositide-3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway. Analysis of circulating tumor DNA (ctDNA) provides a minimally invasive approach to detect clinically actionable PIK3CA mutations. Patients and methods We analyzed PIK3CA hotspot mutation frequency by droplet digital PCR (QX 200; BioRad) using 16 ng of unamplified plasma-derived cell-free DNA from 68 patients with advanced solid tumors (breast cancer, n = 41; colorectal cancer, n = 13; other tumor types, n = 14). Results quantified as variant allele frequencies (VAFs) were compared with previous testing of archival tumor tissue and with patient outcomes. Results Of 68 patients, 58 (85%) had PIK3CA mutations in tumor tissue and 43 (74%) PIK3CA mutations in ctDNA with an overall concordance of 72% (49/68, κ = 0.38). In a subset analysis, which excluded samples from 26 patients known not to have disease progression at the time of sample collection, we found an overall concordance of 91% (38/42; κ = 0.74). PIK3CA-mutated ctDNA VAF of ≤8.5% (5% trimmed mean) showed a longer median survival compared with patients with a higher VAF (15.9 versus 9.4 months; 95% confidence interval 6.7-17.1 months; P = 0.014). Longitudinal analysis of ctDNA in 18 patients with serial plasma collections (range 2-22 time points, median 5) showed that those with a decrease in PIK3CA VAF had a longer time to treatment failure (TTF) compared with patients with an increase or no change (10.7 versus 2.6 months; P = 0.048). Conclusions Detection of PIK3CA mutations in ctDNA is concordant with testing of archival tumor tissue. Low quantity of PIK3CA-mutant ctDNA is associated with longer survival and a decrease in PIK3CA-mutant ctDNA on therapy is associated with longer TTF. Testing for PIK3CA mutations in ctDNA is concordant with testing of tumor tissue. High PIK3CA-mutant abundance in ctDNA was associated with shorter survival. Increasing PIK3CA-mutant abundance in serial blood samples was associated with shorter TTF. Longitudinal monitoring of PIK3CA-mutant ctDNA tracked with cancer clinical course.

Abstract
Objective: To analyze the pathogenesis, clinical manifestations, diagnosis, treatment and prognosis of pulmonary malignant perivascular epithelioid cell tumor (PEComa) with adenocarcinoma. Methods: In August 2020, the Department of Pathology, Dongguan People's Hospital of Southern Medical University, diagnosed a case of pulmonary malignant PEComa mixed with adenocarcinoma. The clinical data, pathological diagnosis, treatment plan and prognosis of the patient were analyzed, and the literature was reviewed. Firstly, "malignant perivascular epithelioid cell tumor"+" Pulmonary "+"adenocarcinoma" was used to search CNKI and Wanfang Medical Database, but no relevant reports were found. Then, we changed the search term as "pulmonary malignant perivascular epithelioid cell tumor", and search for PubMed, Embase, Web of Science and Cochrane by combining the subject terms with "pulmonary malignant perivascular epithelioid cell tumor" and "PEComa" as subtopics. The language was Chinese or English and the search deadline was November 2020. Results: The patient, a 46-year-old male, was admitted to the hospital on August 20, 2020, due to "repeated cough and chest pain for more than 10 days, accompanied by rapid weight loss". Serology detected increased expression of lung non-small cell lung cancer related antigens. PET-CT showed a large mass of soft tissue density in the left thoracic cavity with an SUV value of 22.8. The postoperative pathological diagnosis was malignant PEComa mixed with adenocarcinoma and the lymph nodes were metastasized. Due to the detection of EGFR sensitive mutation, postoperative chemotherapy and targeted therapy were administered, and the current state was stable. A total of 12 cases of pulmonary malignant PEComa were retrieved in the literature, which were common in middle-aged and elderly people. They usually presented with cough or chest tightness. Chest CT mostly showed round masses with clear boundaries, and 8 cases had metastasis to mediastinal lymph nodes and other organs. Conclusions: Pulmonary malignant PEComa is rare. It is the first report of the same mass with lung primary adenocarcinoma. The tumor progresses rapidly. Complete surgical resection of the lesion and lymph node dissection are more appropriate treatment strategies, supplemented by postoperative chemotherapy and targeted therapy. For cases diagnosed as pulmonary PEComa, long term follow-up should be performed, even if the pathological diagnosis is benign.

Abstract
Objective: To investigate the clinicopathological features, differential diagnosis and molecular characteristics of clear cell renal cell carcinoma (ccRCC) with hemangioblastoma component (ccRCC-HBc). Methods: Two ccRCC-HBc cases diagnosed at Fujian Provincial Hospital in September 2015 and March 2016, respectively, were included. Their morphological, immunohistochemical and molecular features were analyzed, including fluorescence in situ hybridization (FISH) detection of TFE3, TFEB and VHL genes. Related literature was reviewed to reveal the characteristics of this tumor. Results: The two cases occurred in 2 women, aged 33 and 66 years, respectively. The maximum diameters of the tumors were 4.0 cm and 8.5 cm, respectively. Histologically, the ccRCC component, representing approximate 10%-20% of the neoplasm, while the tumor cells arranged in flaky, nested, and solid distribution. The tumor cells had conspicuous nucleoli, with rich thin-wall capillary network in the stroma. The hemangioblastoma-like component, representing approximate 60%-70% of the neoplasm, showed a rich capillary network of single-layered flat endothelial cells enclosing stromal cells. The latter cell type showed a pale or eosinophilic cytoplasm exhibiting occasional lipid droplets. Rare cell nuclei appeared enlarged, pleomorphic, or bizarre. The two components were intermingled with each other. Immunohistochemically, the tumor cells were positive for PAX8, CKpan, EMA, vimentin, CD10, RCC, CAⅨ, and P504s in ccRCC area; in another area, the tumor cells were positive for α-inhibin, CD34 and vimentin, while CD10 were weakly positive. Neither TFE3 or TFEB gene split signal was detected in the 2 cases (0/2), nor was VHL gene mutation in case 2 (0/1). Conclusion: ccRCC-HBc is an extremely rare entity of ccRCC. The diagnosis is mainly based on clinical and pathological characteristics, as well as immunohistochemistry. Molecular pathology is helpful for its differential diagnosis. The primary approach of treating ccRCC-HBc is complete surgical excision and chemotherapy. The targeted treatment is helpful if possible.

Abstract
Objective: To explore the molecular features and prognostic value of RAS mutations in patients with myelodysplastic syndromes (MDS) . Methods: 112-gene targeted sequencing was conducted to detect RAS mutations in 776 patients with newly diagnosed primary MDS from December 2011 to December 2018. The mutual exclusivity and co-occurrence in gene mutations and clonal architecture were explored. Moreover, the prognostic significance of RAS mutations in MDS was analyzed. Results: RAS gene mutations were found in 52 (6.7% ) cases, 38 (4.9% ) of whom harbored NRAS mutation, 18 (2.3% ) KRAS mutation, and 4 (0.5% ) both NRAS and KRAS mutations. All the NRAS mutations and 65% of the KRAS mutations were located in codons 12, 13, and 61. PTPN11, FLT3, U2AF1, RUNX1, WT1, ETV6, and NPM1 mutations were enriched in patients with RAS mutations (Q<0.05) . Around 80% of RAS mutations represented subclonal lesions in patients who harbored at least two different mutations. Patients with RAS mutations were more frequently diagnosed with MDS with excess blast (MDS-EB) (82.7% vs. 35.2% , P<0.001) and had higher levels of white blood cell count (4.33×10(9)/L vs. 2.71×10(9)/L, P<0.001) , neutrophil absolute count (2.13×10(9)/L vs. 1.12×10(9)/L, P<0.001) , and bone marrow blast percentage (7% vs. 2% , P<0.001) but lower levels of platelet count (48×10(9)/L vs. 62×10(9)/L, P=0.048) . RAS mutations were correlated with higher-risk categories in the Revised International Prognostic Scoring System (IPSS-R) (71.1% vs. 37.9% , P<0.001) . The median overall survival of patients with NRAS mutations was shorter than the others (P=0.011) , while the significance was lost in the multivariable model. Conclusion: RAS gene mutations always occurred in the late-stage MDS and co-occurred with other signal transduction- and transcription factor-related gene mutations. PTPN11, a RAS pathway-related gene, is an independent poor prognostic factor in MDS patients.

Abstract
Objective: To investigate the clinicopathologic features, differential diagnosis, immunohistochemical profiles and molecular characteristics of primary extraskeletal osteosarcoma (ESOS). Methods: Ten cases of ESOS diagnosed and treated in Fujian Provincial Hospital, Fuzhou, China from January 2003 to January 2019 were collected and subjected to immunohistochemical staining and molecular analyses. The patients were followed up by telephone interview. Relative literature was also reviewed to assess the characteristics of this tumor. Results: The ten cases occurred in 3 women and 7 men, aged from 36 to 85 years (median, 60 years). The sizes of these tumors ranged from 5.5 to 17.5 cm (median, 11.0 cm). Histologically, at low magnification, the tumors were nodular, leafy and lobulated. They were composed of spindle cells, neoplastic osteoid cells, and cartilage tissues, with unequally-proportional mixture of these components. The three components intermingled with each other. Immunohistochemistry profiling showed that the tumor cells were positive for SATB2 (9/9), while α-SMA (4/10) and EMA (1/10) stains were focally positive. Ki-67 proliferation index was 10%‒50%. Desmin, CD68, S-100 protein, SOX10, HMB45, CD117, DOG1, CD34, CKpan, GATA3 and PAX8 stains were negative. MDM2/CDK4 gene amplification signals were not detected in the 6 cases (0/6), which were subjected to the FISH. The SSX18 break-apart signal and the C-KIT and PDGFR-α mutations were not detected (0/5 and 0/3, respectively). Conclusions: Primary ESOS is an extra-osseous osteogenic tumor. The diagnosis is mainly dependent on clinical, radiological and pathological characteristics. Immunohistochemistry and molecular profiling are helpful for making the correct diagnosis.

The tumors ranged 3.2-7.3 cm in the greatest diameter (average 5.1 cm).Microscopically, the tumor showed a biphasic pattern with epithelial cells merging gradually with the spindle cell component. The two areas transited to each other or had obvious boundary. Both components showed mild atypia. No mitosis was observed in either area, and a small number of lymphocytes were observed in the stroma. Immunohistochemical staining showed that epithelioid cells were positive for CKpan, p63 and E-cadherin. Spindle cells were positive for vimentin and EMA, while the Ki-67 index was less than 5%, and lymphocytes were negative for TdT. MAML2 gene apart signal was detected in two of the cases (2/4) that were tested by FISH. Conclusions: MT is a low-grade malignant epithelioid thymic tumor. Its diagnosis and differential diagnosis are dependent on the morphological characteristics, immunohistochemical staining and MAML2 gene detection. The primary treatment option is surgical resection, with an overall good prognosis.

Abstract
Objective: To investigate the clinicopathological features, diagnosis, differential diagnosis, and molecular alterations of malignant gastrointestinal neuroectodermal tumor (MGNET). Methods: Four cases of MGNET were collected at Fujian Provincial Hospital, from July 2013 to January 2019. H&E and immunohistochemical staining were retrospectively evaluated, together with genetic mutation analysis of EWSR1. The relevant literature was systematically reviewed. Results: There were two male and two female patients, with an age range of 34-81 (median 57) years. Tumor sizes ranged from 5-9 (median 6.8) cm. Microscopy showed diffuse and flaky growth of tumor cells, some of which were small and round. The tumor cells were arranged in solid, flaky, nested or pseudoadenoid patterns. The tumor cells were epithelioid, oval, short spindled, or small, with round or oval nuclei. The cytoplasm was eosinophilic or clear. Osteoclast-like multinucleated giant cells were scattered focally. Mitosis was about (2-10)/10 HPF. Immunohistochemically, the tumor cells were positive for S-100 protein (4/4), SOX10 (4/4), Syn (2/4), INI1 (4/4), H3K27Me3 (4/4) and vimentin (4/4). Ki-67 index was 15%-90%. Gene mutation detection confirmed EWSR1 mutation in all four cases, and C-KIT/PDGFRα genes were not mutated in two cases. Conclusions: MGNET is a rare high grade malignant soft tissue tumor. The diagnosis is based on clinicopathological, immunophenotypic, and molecular pathology features. The primary treatment for MGNET is complete surgical excision and chemotherapy; the prognosis is poor.

Abstract
Objective: To explore the features and clinical significance of gene mutations in patients with myelodysplastic syndromes with ring sideroblasts (MDS-RS) . Methods: A total of 255 newly diagnosed primary MDS-RS patients were retrospectively reviewed from our center from January2001 to June 2019. SF3B1 gene mutations were detected by Sanger sequencing in 129 patients, and next generation sequencing (NGS) was performed in the other 126 patients using a set of selected 112-genes. Results: A total of 193 (75.7%) patients presented with SF3B1 mutation, predominantly mutant at amino acid position 700 (K700E) (n=147, 76.2%) . Non-SF3B1 gene mutations were TET2 (16.7%) , ASXL1 (14.3%) , U2AF1 (11.1%) , TP53 (7.9%) , SETBP1 (6.3%) , and RUNX1 (6.3%) . RS 5%-<15% patients had a higher SETBP1 mutation frequency than RS≥15% patients (21.4% vs 4.5%, P=0.044) . Mutation frequencies of other genes were similar in both groups (all P>0.05) . SF3B1 variant allele frequencies (VAF) had positive correlation with marrow RS percentage but without statistical significance in RS 5%-<15% group (P=0.078, r=0.486) . SF3B1 mutant patients presented with higher marrow RS percentage compared with wild-type patients[40.0% (15.0%-80.0%) vs 25.5% (15.0%-82.0%) , P<0.001], and SF3B1 VAF positively correlated with RS percentage (P=0.009, rs=0.261) in RS≥15% group. Age, ANC, PLT, mean RBC corpuscular volume, RS percentage, IPSS-R cytogenetics, and IPSS-R risk score were significantly different between patients with SF3B1 mutations and wild-type SF3B1 (all P<0.05) . Multivariable survival analyses adjusted by age and IPSS-R cytogenetics revealed that SF3B1 mutation was an independent favorable prognostic factor (HR=0.265, 95% CI 0.077-0.917, P=0.036) , and TP53 mutation was an adverse variable independent of SF3B1 mutation (HR=6.272, 95% CI 1.725-22.809, P=0.005) . According to the mutant status of SF3B1 and TP53, MDS-RS patients were categorized into 4 groups, namely, with SF3B1 and TP53 mutation, with wild-type SF3B1 and TP53, with wild-type SF3B1 but TP53 mutation, and with SF3B1 mutation but wild-type TP53. There was a significant difference for OS among these 4 groups (P<0.001) . The former 3 groups showed no significant difference in OS in multiple comparisons. However, the SF3B1 mutation but wild-type TP53 group had a better OS than wild-type SF3B1 but TP53 mutation group and wild-type SF3B1 and TP53 group, whereas a similar OS compared with SF3B1 and TP53 mutation group. Conclusion: SF3B1 mutations were prevalent in MDS-RS patients with the most common mutation at amino acid position 700 (K700E) . SF3B1 mutation was an independent favorable prognostic variable, whereas TP53 mutation was an independent adverse variable. SF3B1 mutation could coordinate with TP53 mutation for more sophisticated prognosis stratification in MDS-RS patients.

Abstract
Objective: To investigate the clinicopathological features, diagnosis, differential diagnosis and immunohistochemical (IHC) characteristics of paraganglioma of urinary bladder (PUB). Methods: The clinical and pathological data of 23 cases of PUB were collected at the Second Affiliated Hospital of Fujian Medical University (7 cases); Fujian Provincial Hospital (8 cases); Fujian Medical University Union Hospital (6 cases); and First Affiliated Hospital of Fujian Medical University (2 cases) from May 2010 to November 2018. IHC staining for CK, GATA3, CD56, Syn, CgA, S-100 protein, HMB45, SDHB, OCT3/4 and Ki-67 was done using EliVision method; and the relevant literature was reviewed. Results: There were 14 women and 9 men, aged ranged from 21 to 73 years (median 51 years). Clinically, patients presented with headache, vertigo, palpitation, hypertensive crisis during micturition, hypertension, blurred vision, gross hematuria and paroxysmal pallor. The tumor sizes ranged from 0.9 to 6 cm (mean2.5 cm). Macroscopically, most tumors were exophytic and well delineated within the lamina propria or muscularis propria. The tumors were firm and nodular and showed grayish-tan cut surface. Histologically,the tumor growth pattern was expansive or showed interpenetrating infiltrative growth within the lamina propria or muscularis propria; the tumor cells were typically arranged in distinctive nests (Zellballen) with organoid arrangement; pseudo-rosette were seen in some cases. The cells were rounded or polygonal and had rich, acidophilic or amphophilic cytoplasm and may contain pigmented granules and vacuoles; the nuclei were central or eccentric, with small nucleoli, although occasionally some nuclei were pleomorphic and hyperchromatic. Spindled sustentacular cells could be seen around the nests of tumor cells in some cases. There were abundant vessels that were fissure-like, hemangioma-like or dilated. By IHC, the tumor cells were positive for GATA3 (2/23), OCT3/4 (2/23), CD56 (22/23), Syn (23/23), CgA (22/23), S-100 (sustentacular cell, 23/23) and SDHB (23/23); and negative for CK and HMB45; Ki-67 index was 1%-5%. At follow-up, there was no recurrence or metastasis in 18 cases. Conclusions: The diagnosis of PUB relies on the morphologic and IHC features; but there may be histomorphologic heterogeneity. The most important differential diagnosis is invasive urothelial carcinoma. The tumor cells may show aberrant cytoplasmic expression of OCT3/4; there is no clear correlation between SDHB and OCT3/4 expression in the group.

Abstract
Objective: To investigate the incidence and risk factors of lower extremities deep venous thrombosis (DVT) in patients with chronic refractory wounds (chronic wounds). Methods: A retrospective analysis of 722 cases of chronic wounds admitted to the First People's Hospital of Zhengzhou from January 1, 2015 to December 31, 2018 was carried out, and clinical data such as gender, age, wound involves the lower extremities, wound type, duration of wound, D-dimer level and complicated diabetes, hypertension, coronary heart disease, cerebral infarction, pneumonia and sepsis/septic shock were collected. The patients were divided into DVT group and non-DVT group according to the color ultrasound test. Multivariate binary logistic regression analysis was used to screen the independent risk factors of DVT in patients with chronic wounds. Results: There were 55 (7.6%) patients in DVT group, of which 44(80.0%) were diagnosed as chronic DVT by conventional lower extremities venous color ultrasound screening at admission, and the remaining 11(20.0%) were newly diagnosed during hospitalization. There were no significant differences in gender, wound involves the lower extremities, duration of wound, complicated diabetes and hypertension between DVT group and non-DVT group (all P>0.05); and the differences were statistically significant in age, wound type, D-dimer level, complicated coronary heart disease, cerebral infarction, pneumonia and sepsis/septic shock (all P<0.05). Multivariate binary logistic regression analysis showed age [OR=2.260 (95%CI: 1.584-3.224)], D-dimer level [OR=14.201 (95%CI: 6.101-33.055)], complicated coronary heart disease [OR=2.731 (95%CI: 1.210-6.162)] and sepsis/septic shock [OR=3.170 (95%CI: 1.115-9.016)] were independent risk factors for DVT (all P<0.05). Conclusion: Chronic wounds patients have a higher incidence of DVT, most of which are chronic DVT, and age, D-dimer level, complicated coronary heart disease and sepsis/septic shock are independent risk factors for DVT in chronic wounds.

Abstract
目的 探讨平均红细胞体积(MCV)对骨髓增生异常综合征(MDS)预后的影响。 方法 收集2009年12月至2017年12月我中心新诊断、无红细胞输注史的321例原发性MDS患者,回顾性分析MCV水平对整体及不同骨髓原始细胞水平患者总生存(OS)期的影响。 结果 全部患者按照MCV水平高低分为MCV≤100 fl组(148例)和MCV>100 fl组(173例)。MCV≤100 fl组患者中位OS时间为27(95%CI 19~35)个月,MCV>100 fl组患者中位OS时间为72(95%CI 5~139)个月,差异有统计学意义(P<0.001)。亚组分析示,在骨髓原始细胞<5%的患者中,MCV≤100 fl患者的中位OS期较MCV>100 fl者显著缩短(P=0.002);而在骨髓原始细胞≥5%的患者中,MCV水平对OS的影响不显著(P=0.078)。在纳入其余临床指标及基因突变校正后,MCV≤100 fl仍为骨髓原始细胞<5%患者的独立不良预后因素(HR=1.890,95%CI 1.007~3.548,P=0.048)。对不同MCV水平骨髓原始细胞<5%的MDS患者的临床及实验室指标进行分析,结果显示MCV≤100 fl组患者外周血HGB高于MCV>100 fl组[90(42~153)g/L对78.5(28~146)g/L,P=0.015],IPSS-R高危/极高危组比例及IPSS-R染色体核型分组差/很差比例明显高于MCV>100 fl组,差异有统计学意义(28.8%对10.8%,P=0.003;24.7%对12.9%,P=0.049)。MCV≤100 fl组患者平均基因突变数目较MCV>100 fl组多(0.988个对0.769个,P=0.064),SF3B1突变较MCV>100 fl组少见(4.7%对15.4%,P=0.018)。 结论 MCV≤100 fl为骨髓原始细胞<5%的MDS患者独立于基因突变及其他临床指标的预后不良因素。

Abstract
Microbial volatile organic compounds (mVCs) are formed in the metabolism of microorganisms and widely distributed in nature and pose threats to human health. However, the air pollution by microorganisms is a situation which is poorly understood. In this study, the cytotoxicity of E. aerogenes VCs was evaluated in the model organism Saccharomyces cerevisiae. E. aerogenes VCs inhibited the survival of yeast and triggered the formation of intracellular reactive oxygen species (ROS). The hypersensitive of MAP kinase mpk1/slt2 and 19S regulatory assembly chaperone adc17 mutants to the E. aerogenes VCs indicated cell wall integrity (CWI) pathway together with stress-inducible proteasome assembly regulation are essentially involved in mVCs tolerance mechanism. Furthermore, exposure to the mVCs resulted in the transcriptional upregulation of the CWI pathway, the regulatory particle assembly chaperones, and genes involved in proteasome regulations. Our research suggested that the ROS/MAPK signaling and proteasome regulatory pathway play pivotal roles in the integration and fine-tuning of the mVCs stress response. This study provides a molecular framework for future study of the effects of mVCs on more complex organisms, such as humans.

Abstract
Objective: To explore the clinical effects of antibiotic bone cement in the treatment of diabetic foot ulcers. Methods: According to the treatment methods, 18 patients with diabetic foot ulcers (11 males and 7 females, aged 53-79 years), who were conformed to the study criteria and admitted to our hospital from January 2016 to January 2017, were enrolled in traditional group; 18 patients with diabetic foot ulcers (11 males and 7 females, aged 55-80 years), who were conformed to the study criteria and admitted to our hospital from February 2017 to February 2018, were enrolled in bone cement group. Wounds of patients in traditional group were treated with vacuum sealing drainage after conventional debridement. Wounds of patients in bone cement group were covered with antibiotic bone cement after conventional debridement. The number of patients with positive bacterial culture in wound exudate in the 2 groups on admission and 3, 6, 9, and 15 days after surgery, the length of hospital stay, the number of operation, and the wound complete healing time were retrospectively recorded. Data were processed with Fisher's exact probability test and independent sample t test. Results: Compared with (29±10) d and (4.6±1.2) times of patients in traditional group, the length of hospital stay [(9±3) d] of patients was obviously shortened, the number of operation [(1.3±0.6) times] of patients was obviously reduced, the number of patients with positive bacterial culture in wound exudate at each time point post surgery was obviously reduced (t=8.177, 9.896, P<0.05 or P<0.01) in bone cement group. There were no statistically significant differences in the number of patients with positive bacterial culture in wound exudate on admission and wound complete healing time between patients in the 2 groups (t=0.175, P>0.05). Conclusions: The antibiotic bone cement treatment of diabetic foot ulcers can reduce the number of patients with positive bacterial culture in wound exudate and the number of operation, as well as shorten the length of hospital stay.

Abstract
目的 探讨伴TP53基因异常骨髓增生异常综合征(MDS)患者的临床特征及预后。 方法 回顾性分析2009年10月至2017年12月中国医学科学院血液病医院新诊断的584例原发性MDS患者临床资料,采用包含112个血液肿瘤相关基因的靶向测序技术进行突变分析,并采用间期荧光原位杂交(FISH)技术检测TP53基因缺失。分析TP53基因突变和(或)缺失与临床特征之间的关系及其对患者总生存(OS)的影响。 结果 42例(7.2%)伴TP53基因异常,其中单纯基因突变31例(5.3%),单纯基因缺失8例(1.4%),同时伴有突变和缺失3例(0.5%)。34例伴TP53基因突变患者中共检测到37个TP53突变,其中35个位于DNA结合结构域(第5~8号外显子),1个位于第10号外显子,1个为剪切位点突变。伴TP53基因异常组的平均基因突变数目(2.52个)显著高于无异常组(1.96个)(z=−2.418,P=0.016)。伴TP53基因异常患者的中位年龄[60(21~78)岁]高于无异常患者[52(14~83)岁](z=−2.188,P=0.029);伴TP53基因异常组中复杂核型比例、IPSS较高危组(中危-2及高危)比例显著高于无异常组(P值均<0.001)。伴TP53基因异常组的中位OS期[13(95%CI 7.57~18.43)个月]较无异常组(未达到)显著缩短(χ2=12.342,P<0.001),但多因素模型纳入复杂核型进行校正后,TP53突变不再是独立预后因素。 结论 伴TP53基因异常MDS患者中基因突变较基因缺失常见,突变位点主要分布于DNA结合结构域。TP53基因异常与复杂核型相关,且常与多个基因突变相伴出现。在多因素模型纳入复杂核型校正后,TP53基因异常则不再是独立的预后因素。

Abstract
BACKGROUND Head formation of broccoli (Brassica oleracea var. italica) is greatly reduced under high temperature (22 °C and 27 °C). Broccoli inbred lines that are capable of producing heads at high temperatures in summer are varieties that are unique to Taiwan. However, knowledge of the early-activated pathways of broccoli head formation under high temperature is limited. RESULTS We compared heat-tolerant (HT) and heat-sensitive (HS) transcriptome of broccoli under different temperatures. Weighted gene correlation network analysis (WGCNA) revealed that genes involved in calcium signaling pathways, mitogen-activated protein kinase (MAPK) cascades, leucine-rich repeat receptor-like kinases (LRR-RLKs), and genes coding for heat-shock proteins and reactive oxygen species homeostasis shared a similar expression pattern to BoFLC1, which was highly expressed at high temperature (27 °C). Of note, these genes were less expressed in HT than HS broccoli at 22 °C. Co-expression analysis identified a model for LRR-RLKs in survival-reproduction tradeoffs by modulating MAPK- versus phytohormones-signaling during head formation. The difference in head-forming ability in response to heat stress between HT and HS broccoli may result from their differential transcriptome profiles of LRR-RLK genes. High temperature induced JA- as well as suppressed auxin- and cytokinin-related pathways may facilitate a balancing act to ensure fitness at 27 °C. BoFLC1 was less expressed in HT than HS at 22 °C, whereas other FLC homologues were not. Promoter analysis of BoFLC1 showed fewer AT dinucleotide repeats in HT broccoli. These results provide insight into the early activation of stress- or development-related pathways during head formation in broccoli. The identification of the BoFLC1 DNA biomarker may facilitate breeding of HT broccoli. CONCLUSIONS In this study, HT and HS broccoli genotypes were used to determine the effect of temperature on head formation by transcriptome profiling. On the basis of the expression pattern of high temperature-associated signaling genes, the HS transcriptome may be involved in stress defense instead of transition to the reproductive phase in response to heat stress. Transcriptome profiling of HT and HS broccoli helps in understanding the molecular mechanisms underlying head-forming capacity and in promoting functional marker-assisted breeding.

Abstract
Cetuximab, an epidermal growth factor receptor (EGFR)-targeting monoclonal antibody (mAb), is a novel targeted therapy for the treatment of patients with oral cancer. Cetuximab can be used in combination with chemotherapeutic agents to prolong the overall survival rates of patients with oral cancer. Curcumin is a traditional Chinese medicine, and it has been demonstrated to have growth-inhibiting effects on oral cancer cells. However, information regarding the combination of cetuximab and curcumin in drug-resistant oral cancer cells is lacking, and its underlying mechanism remains unclear. The purpose of the present study was to explore the oral anticancer effects of cetuximab combined with curcumin on cisplatin-resistant oral cancer CAR cell apoptosis in vitro. The results demonstrated that combination treatment synergistically potentiated the effect of cetuximab and curcumin on the suppression of cell viability and induction of apoptosis in CAR cells. Cetuximab and curcumin combination induced apoptosis and dramatically increased caspase-3 and caspase-9 activities compared with singular treatment. Combination treatment also markedly suppressed the protein expression levels of EGFR and mitogen-activated protein kinases (MAPKs) signaling (phosphorylation of ERK, JNK and p38). The results demonstrated that co-treatment with cetuximab and curcumin exerts synergistic oral anticancer effects on CAR cells through the suppression of the EGFR signaling by regulation of the MAPK pathway.

Abstract
Oral squamous cell carcinoma (OSCC) is a type of cancer with high morbidity and mortality rates worldwide; it also demonstrates chemotherapeutic resistance. Triterpenoid ursolic acid has been shown to exhibit various biological activities and anticancer effects in several preclinical studies. In our previous study, human cisplatin‑resistant oral cancer CAR cells were established, and the present study aimed to further examine the effects of ursolic acid on CAR cells. The results revealed that ursolic acid inhibited CAR cell viability, as determined using a 3‑(4,5‑dimethylthiazol‑2‑yl)‑2,5‑diphenyltetrazolium bromide assay. Ursolic acid‑induced cell death was mediated through a caspase‑dependent pathway, determined with the pan‑caspase inhibitor, z‑VAD‑fmk. Ursolic acid also increased the activities of caspase‑3 and caspase‑9 in CAR cells, determined by a colorimetric assay. Specifically, the production of reactive oxygen species and loss of mitochondrial membrane potential, detected by flow cytometry, were observed in the ursolic acid‑treated CAR cells. The apoptosis‑associated signaling showed that ursolic acid decreased the phosphorylation of AKT (Ser473) and B‑cell lymphoma 2 (Bcl‑2)‑associated agonist of cell death (BAD; Ser136), and the protein levels of Bcl‑2 and Bcl‑extra large (Bcl‑xL), and increased the expression of BAD and Bcl‑2‑associated X (Bax) protein in CAR cells. In summary, the results supported the potential application of ursolic acid against drug‑resistant oral carcinoma and to improve oral anticancer efficacy in the near future.

Abstract
Background Targeted methylation sequencing of plasma cell-free DNA (cfDNA) has a potential to expand liquid biopsies to patients with tumors without detectable oncogenic alterations, which can be potentially useful in early diagnosis. Patients and methods We developed a comprehensive methylation sequencing assay targeting 9223 CpG sites consistently hypermethylated according to The Cancer Genome Atlas. Next, we carried out a clinical validation of our method using plasma cfDNA samples from 78 patients with advanced colorectal cancer, non-small-cell lung cancer (NSCLC), breast cancer or melanoma and compared results with patients' outcomes. Results Median methylation scores in plasma cfDNA samples from patients on therapy were lower than from patients off therapy (4.74 versus 85.29; P = 0.001). Of 68 plasma samples from patients off therapy, methylation scores detected the presence of cancer in 57 (83.8%), and methylation-based signatures accurately classified the underlying cancer type in 45 (78.9%) of these. Methylation scores were most accurate in detecting colorectal cancer (96.3%), followed by breast cancer (91.7%), melanoma (81.8%) and NSCLC (61.1%), and most accurate in classifying the underlying cancer type in colorectal cancer (88.5%), followed by NSCLC (81.8%), breast cancer (72.7%) and melanoma (55.6%). Low methylation scores versus high were associated with longer survival (10.4 versus 4.4 months, P < 0.001) and longer time-to-treatment failure (2.8 versus 1.6 months, P = 0.016). Conclusions Comprehensive targeted methylation sequencing of 9223 CpG sites in plasma cfDNA from patients with common advanced cancers detects the presence of cancer and underlying cancer type with high accuracy. Methylation scores in plasma cfDNA correspond with treatment outcomes.

Abstract
Diverse soil microbial community is determinant for sustainable agriculture. Rich microbial diversity has presumably improved soil health for economic crops to grow. In this work, the benefits of paddy-upland rotation on soil microbial diversity and specific microbes are thus intensively explored. The microbiome from multiple factor experiment (three fertilizations coupled with two rotation systems) were investigated by novel enrichment and co-occurrence analysis in a field well maintained for 25 years. Using next-generation sequencing technique, we firstly present explicit evidence that different rotation systems rather than fertilizations mightily governed the soil microbiome. Paddy-upland rotation (R1) obviously increase more microbial diversity than upland rotation (R2) whether organic (OF), chemical (CF) or integrated fertilizers (IF) were concomitantly applied. Besides, the specific bacterial composition dominated in OF soil is more similar to that of R1 than to CF, suggesting that paddy-upland rotation might be the best option for sustainable agriculture if chemical fertilizer is still required. Interestingly, the pot bioassay verified clearly the novel analysis prediction, illustrating that greater microbial diversity and specific microbial composition correlated significantly with disease resistance. This finding highlights the eminence of paddy-upland rotation in promoting microbial diversity and specific microbial compositions, preserving soil health for sustainable agriculture.

Abstract
Objective: To observe effects of exogenous high mobility group protein box 1 (HMGB1) on angiogenesis in ischemic zone of early scald wounds of rats. Methods: Thirty-six Sprague-Dawley rats were divided into HMGB1 group and simple scald (SS) group according to the random number table, with 18 rats in each group. Comb-like copper mould was placed on the back of rats for 20 s after being immersed in 100 ℃ hot water for 3 to 5 min to make three ischemic zones of wound. Immediately after scald, rats in HMGB1 group were subcutaneously injected with 0.4 μg HMGB1 and 0.1 mL phosphate buffer solution (PBS), and rats in SS group were subcutaneously injected with 0.1 mL PBS from boarders of ischemic zone of scald wound. At post scald hour (PSH) 24, 48, and 72, 6 rats in each group were collected. Protein expressions of vascular endothelial growth factor (VEGF) in ischemic zone of wound at PSH 24, 48, and 72 and protein expressions of CD31 in ischemic zone of wound at PSH 48 and 72 were detected by immunohistochemistry. The number of microvessel in CD31 immunohistochemical sections of ischemic zone of wound at PSH 48 and 72 was calculated after observing by the microscope. The mRNA expressions of VEGF and CD31 in ischemic zone of wound were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction at PSH 24, 48, and 72. Data were processed with analysis of variance of factorial design, t test, and Bonferroni correction. Results: (1) At PSH 24, 48, and 72, protein expressions of VEGF in ischemic zone of wound of rats in HMGB1 group were significantly higher than those of rats in SS group (t=7.496, 4.437, 5.402, P<0.05 or P<0.01). At PSH 48 and 72, protein expressions of CD31 in ischemic zone of wound of rats in HMGB1 group were 0.038 8±0.007 9 and 0.057 7±0.001 2 respectively, significantly higher than 0.013 4±0.004 9 and 0.030 3±0.004 0 of rats in SS group (t=10.257, 15.055, P<0.01). (2) At PSH 48 and 72, the number of microvessel in ischemic zone of wound of rats in HMGB1 group was obviously more than that of rats in SS group (t=3.536, 4.000, P<0.05). (3) At PSH 24, 48, and 72, mRNA expressions of VEGF in ischemic zone of wound of rats in HMGB1 group were significantly higher than those of rats in SS group (t=4.406, 3.821, 3.356, P<0.05). At PSH 24 and 48, mRNA expressions of CD31 in ischemic zone of wound of rats in HMGB1 group were significantly higher than those of rats in SS group (t=4.113, 3.466, P<0.05). At PSH 72, mRNA expressions of CD31 in ischemic zone of wound of rats in 2 groups were close (t=0.010, P>0.05). Conclusions: Exogenous HMGB1 can promote angiogenesis in ischemic zone of early scald wounds of rats by increasing expressions of VEGF and CD31.

Abstract
Objective: To investigate the clinicopathological features, differential diagnosis, and genetic alteration of Langerhans cell sarcoma (LCS). Methods: Four cases of LCS were collected from Fujian Provincial Hospital and Fuzhou General Hospital of Nanjing Military Command of PLA from July 2013 to January 2017. Clinicopathological features and immunophenotype were retrospectively reviewed in four LCS cases combined with genetic mutation analysis of BRAF and ALK. Results: Four cases included 2 women and 2 men with ages from 42 to 79 years (median=59.3 years). The size of the tumors ranged from 2.5-7.8 cm. Histologically, at the low power field, the tumors consisted of highly cellular proliferation in fascicules, whirlpool and diffuse sheets arrangement. The tumor cells were kidney-or horseshoe-shaped to round epithelioid cells or enlarged spindle cells. The neoplastic cells showed cytological atypia, hyperchromatic nuclei with prominent 1 to 2 nucleoli. Multinucleated giant cells were also found. Mitotic activity was approximately (50-70) mitoses/10 HPF. Immunohistochemically, the tumor cells were positive for S-100 protein (4/4), SOX10(3/4), Langerin/CD207(4/4), CD1a(3/4), CD68(3/4), CD163(3/4), and INI-1(4/4). Ki-67 index was 30%-80%. Gene mutation analysis showed that one case had BRAF V600E mutation but none had ALK gene alteration. Conclusions: LCS is a rare tumor with highly malignant potential and distinct morphologic features.The primary treatment for LCS is completely surgical excision and chemotherapy. The prognosis is generally poor.

Abstract
Objective: To study the characteristics of gene mutations in Chinese myelodysplastic syndromes (MDS) patients. Methods: A total of 511 Chinese patients with MDS performed 112-gene targeted sequencing were retrospectively analyzed. Results: Eighty-three distinct mutant genes were found in 511 patients with MDS. Amongst these, the most frequent mutations was associated with epigenetics (50%) , followed by spliceosome (37%) , signal transduction (34%) , transcription factors (24%) and cell cycle/apoptosis (17%) . 439 subjects (86%) had at least one gene mutation. The mean number of mutations in refractory anemia with unilineage dysplasia (RCUD) was 1.25, refractory anemia with multilineage dysplasia (RCMD) was 1.73, refractory anemia with ring sideroblasts (RARS) was 2.79, refractory anemia with excess blasts-1 (RAEB-1) was 2.22, RAEB-2 was 2.34, MDS with isolated 5q- was 2.67, MDS, unclassified (MDS-U) was 2.00. U2AF1 mutant subjects were more likely to have isolated+8[Q<0.001, OR=4.42 (95% CI 2.23-8.68) ]and less likely to have complex karyotypes[Q=0.005, OR=0.22 (95% CI 0.04-0.72) ]. According to the number of gene mutations, all subjects were categorized into three groups, namely group with 0-1 mutation, with 2 mutations and with three or more mutations. There was a significant difference in overall survival (OS) among three groups (P=0.041) . Conclusion: About 90% patients with MDS have at least one gene mutation. Genes associated with epigenetics and spliceosome are most common mutated genes in MDS. The increased numbers of gene mutations accompany with disease evolution and associate with poor prognosis.
