Abstract
Objectives: To investigate the application value of laparoscopic double stapler firings and double stapling technique combined with rectal eversion and total extra-abdominal resection (LDER) in the anal preservation treatment of low rectal cancer. Methods: Inclusion criteria: (1) age was 18-70; (2) the distance of the lower tumor edge from the anal verge was 4-5 cm; (3) primary tumor with a diameter ≤3 cm; (4) preoperative staging of T1~2N1~2M0; (5) "difficult pelvis", defined as ischial tuberosity diameter<10 cm or body mass index>25 kg/m2; (6) patients with strong intention for sphincter preservation; (7) no preoperative treatment (e.g., chemotherapy, radiotherapy, molecular targeted therapy, or immunotherapy); (8) no lateral lymph node enlargement; (9) no previous anorectal surgery; (10) patients with good basic condition who could tolerate surgery. Exclusion criteria: (1) previously suffered from malignant tumors of the digestive tract or currently suffering from malignant tumors out of the digestive tract; (2) patients with preoperative anal dysfunction (Wexner score ≥ 10), or fecal incontinence. The specific surgical steps are as follows: the distal end of the rectum was dissected to the level of the interspace between internal and external sphincters of anal canal. Five centimeters proximal to the tumor, the mesorectum was ligated, and a liner stapler was used to transect the rectum. The distal rectum with the tumor were then everted and extracted through the anus. The rectum was transected 0.5-1.0 cm distal to the tumor with a linear stapler. Full thickness suture was used to reinforce the stump of the rectum, which was then brought back into the pelvic cavity. Finally, an end-to-end anastomosis between the colon and the rectum was performed. A retrospective descriptive study was performed of the clinical and pathological data of 12 patients with T1-T2 stage low rectal cancer treated with LDER at Henan Provincial People's Hospital from January 2020 to December 2022. Results: All 12 patients successfully completed LDER with sphincter preservation, without conversion to open surgery or changes in surgical approach. The median surgical time was 272 (155-320) minutes, with a median bleeding volume of 100 (50-200) mL. No protective stoma was performed, and all patients received R0 resection. The average hospital stay was 9 (7-15) days. There were no postoperative anastomotic leakage or perioperative deaths. All 12 patients received postoperative follow-up, with a median follow-up of 12 months (6-36 months) and a Wexner score of 8 (5-14) at 6 months postoperatively. There was no tumor recurrence or metastasis during the follow-up period. Conclusions: LDER is safe and effective for the treatment of low rectal cancer.

Abstract
Ribose 2'-O-methylation is involved in critical biological processes, but its biological functions and significance in mRNAs remain underexplored. We have developed NJU-seq, a sensitive method for unbiased 2'-O-methylation (Nm) profiling, and Nm-VAQ, a site-specific quantification tool. Using these tools in tandem, we identified thousands of Nm sites on mRNAs of human and mouse cell lines, of which 68 of 84 selected sites were further validated to be more than 1% 2'-O-methylated. Unlike rRNA, most mRNA Nm sites were from 1% to 30% methylated. In addition, mRNA Nm was dynamic, changing according to the circumstance. Furthermore, we show that fibrillarin is involved as a methyltransferase. By mimicking the detected Nm sites and the context sequence, the RNA fragments could be 2'-O-methylated and demonstrated higher stability but lower translation efficiency. Last, profiling of Nm sites in lung surgery samples revealed common signatures of lung cancer pathogenesis, providing potential new diagnostic markers.

Abstract
Objective: To investigate the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and interleukin-1beta (IL-1β) in the plasma and bronchoalveolar lavage fluid of silicosis patients with artificial quartz stone plate processing. Methods: In January 2022, 10 patients with artificial quartz stone plate processing silicosis and 20 patients with common silicosis who were hospitalized and diagnosed in a hospital at Zhejiang Province from June 2019 to December 2021 were retrospectively selected as the research objects, and 30 healthy people were selected as the control group during the same period. Plasma of all subjects and bronchoalveolar lavage fluid of all patients were collected. The levels of TNF-α, IL-6 and IL-1β in plasma and bronchoalveolar lavage fluid were detected by enzyme-linked immunosorbent assay and were analyzed. Results: The levels of TNF-α, IL-6 and IL-1β in the plasma of patients with silicosis were higher than those of the control group (P<0.05), and the levels of TNF-α and IL-1β in the plasma of silicosis patients with artificial quartz stone plate processing were higher than those of common silicosis patients (P<0.05). The levels of TNF-α and IL-1β in plasma of artificial quartz stone plate processing silicosis patients were higher than those of common silicosis patients at the same silicon stage (P<0.05). The levels of IL-1β in bronchoalveolar lavage fluid of silicosis patients with artificial quartz stone plate processing was higher than that of patients with common silicosis (P<0.05) . Conclusion: The levels of TNF-α, IL-6 and IL-1β in silicosis patients with artificial quartz stone plate processing are higher than those in patients with common silicosis, which may be related to dust components they are exposed to.

Abstract
PURPOSE/OBJECTIVE(S) Primary small cell carcinoma of esophageal (PSCCE) is a rare malignancy with aggressive behavior associated with a perceived poor prognosis. Due to its rarity, the clinical characteristics and the optimal clinical management have not yet been defined, therefore, we designed a multicenter retrospective study to analyze the prognostic factors and the impact of treatment on the prognosis of PSCCE patients. MATERIALS/METHODS We retrospectively evaluated 704 consecutive patients with PSCCE from five participating centers between April 2008 and July 2021. The PSCCE was diagnosed based on the World Health Organization classification. Treatment strategies included surgery, radiotherapy (RT), or chemotherapy only, and combination of 2-3 treatment modalities (surgery, RT and chemotherapy). The estimated hazard rates provide the trajectory of progression and death overtime. Univariate survival analysis was conducted by using Kaplan-Meier plots, and the log-rank test was used to compare survival differences. Cox regression analysis was used to determine the independent prognostic factors in multivariate analysis. RESULTS Overall, 69.0% (486/704) of the patients were male, with a median age of 63 years (range 38-96). Most of the patients were regional lymph node positive (N+, 64.0%), and nearly half with advanced stage (M+, 47.2%). With a median follow-up time of 16 months, 472 patients (67.0%) exhibited disease progression and 429 patients (60.9%) died. Following initial treatment, 85.1% (402/472) of progression/death and 80.1% (344/429) of mortalities occurred within 24 months. Consistently, the maximum annual death and progression/death hazards are highest in the 15.6 months and 9.6 months. The overall survival (OS) rates at 1, 3 and 5 years for all patients were 65.1%, 26.5% and 18.3%, respectively. Univariate survival analysis showed that ECOG score, alcohol abuse, TNM stage, N stage, and M stage were correlated with OS (P <0.05). Multivariate analysis showed that the N stage (HR: 1.378, P = 0.018) and M stage (HR: 1.945, P <0.001) carried independent prognostic factors for OS. In the term of treatment, the OS rates for M- patients treated with combined modality therapy (CMT, surgery±radiotherapy/chemotherapy) were better than those treated with surgery alone or radiotherapy/chemotherapy (3-year OS: 36.7% VS 25.6% VS 32.2%; P = 0.045). The OS rates for M+ patients treated with chemotherapy alone, radiotherapy alone, or radiotherapy combined with chemotherapy were no significant differences (3-year OS: 12.2% VS 19.4% VS 11.1%; P = 0.400). CONCLUSION PSCCE is characterized by a high degree of malignancy with high risks of lymphatic and distant metastasis, N and M stages are the most important prognostic factor. In terms of treatment, comprehensive treatment is most likely to benefit patients without distant metastasis.

Abstract
Long noncoding RNAs (LncRNAs) may be involved in the occurrence, development, and drug resistance of gastric cancer (GC) by regulating autophagy. This study aims to establish an autophagy-related LncRNA (ARL) signature (ARLSig) and explore its immunogenomic implications in patients with GC. The RNA sequencing and clinical data of patients with GC from The Cancer Genome Atlas database, and autophagy genes from the Human Autophagy Database were extracted. The co-expression and Cox regression analyses were performed to establish a prognostic ARLSig. Further, the differences in clinicopathology, immune microenvironment, immune function, and response to immunotherapy between the risk groups were explored by several algorithms. A prognostic risk model consisting of 11 ARLs was constructed. The clinical correlation analysis between the ARLSig and clinicopathological factors indicated that the ARLSig was correlated with the comprehensive, T, and N stages (all P<0.05). Further, a nomogram including the ARLSig and clinical factors suggested it had a powerful predictive value for survival, with a higher prediction efficiency for 1-, 3-, and 5-year survival than other clinicopathological factors. Finally, the immune-related analysis between the two risk groups showed that the high-risk group had significantly higher infiltration proportions of natural killer cells resting, monocytes, M2 macrophages, and dendritic cells resting, as well as higher expression of 25 immune checkpoint genes. In addition, the immunotherapy response prediction by the tracking of indels by decomposition algorithm showed the low-risk group was more sensitive to immune checkpoint inhibitor therapy. The ARLSig consisting of 11 ARLs in GC showed highly efficient predictive value for survival of patients with GC and might provide novel targets for their individualized immunotherapy.

Abstract
Along with the emergence of green plants on this planet one billion years ago, the nucleotide binding site leucine-rich repeat (NLR) gene family originated and diverged into at least three subclasses. Two of them, with either characterized N-terminal toll/interleukin-1 receptor (TIR) or coiled-coil (CC) domain, serve as major types of immune receptor of effector-triggered immunity (ETI) in plants, whereas the one having a N-terminal Resistance to powdery mildew8 (RPW8) domain, functions as signal transfer component to them. In this review, we briefly summarized the history of identification of diverse NLR subclasses across Viridiplantae lineages during the establishment of NLR category, and highlighted recent advances on the evolution of NLR genes and several key downstream signal components under the background of ecological adaption.

Abstract
Arbuscular mycorrhizal symbiosis (AMS) is an ancient plant-fungus relationship that is widely distributed in terrestrial plants. The formation of symbiotic structures and bidirectional nutrient exchange requires the regulation of numerous genes. However, the landscape of RNAome during plant AMS involving different types of regulatory RNA is poorly understood. In this study, a combinatorial strategy utilizing multiple sequencing approaches was used to decipher the landscape of RNAome in tomato, an emerging AMS model. The annotation of the tomato genome was improved by a multiple-platform sequencing strategy. A total of 3,174 protein-coding genes were upregulated during AMS, 42% of which were alternatively spliced. Comparative-transcriptome analysis revealed that genes from 24 orthogroups were consistently induced by AMS in eight phylogenetically distant angiosperms. Seven additional orthogroups were specifically induced by AMS in all surveyed dicot AMS host plants. However, these orthogroups were absent or not induced in monocots and/or non-AMS hosts, suggesting a continuously evolving AMS-responsive network in addition to a conserved core regulatory module. Additionally, we detected 587 lncRNAs, ten miRNAs, and 146 circRNAs that responded to AMS, which were incorporated to establish a tomato AMS-responsive, competing RNA-responsive endogenous RNA (ceRNA) network. Finally, a tomato symbiotic transcriptome database (TSTD, https://efg.nju.edu.cn/TSTD) was constructed to serve as a resource for deep deciphering of the AMS regulatory network. These results help elucidate the reconfiguration of the tomato RNAome during AMS and suggest a sophisticated and evolving RNA layer responsive network during AMS processes.

Abstract
Rheumatic diseases, a typical kind of autoimmune disease, are often treated with glucocorticoids, immunosuppressants, biological agents, and small-molecule targeted drugs, which often leads to immune dysfunction in patients and increases the risk of activation of latent tuberculosis infection. To regulate the screening, diagnosis, and prophylactic treatment of latent tuberculosis infection in patients with rheumatic diseases, reduce the risk of developing active tuberculosis and improve the prognosis, Peking University Shenzhen Hospital, Shenzhen Third People's Hospital and Peking Union Medical College Hospital jointly organized domestic experts in the field of rheumatology and tuberculosis to establish the expert consensus on the diagnosis and treatment of latent tuberculosis infection in patients with rheumatic diseases.

Abstract
In the field of wound repair, scarless healing and complete reconstruction of skin function are major challenges in clinical and basic research. At present, a variety of artificial dermal scaffolds have been used in the clinical repair of wounds to overcome the problems such as skin structural disorders caused by tissue defects. The biomaterials used to make artificial dermal scaffolds in skin and tissue engineering research mainly include three categories: natural biomaterials, biosynthetic materials, and organic polymer materials. This review summarizes the biocompatibility, bioactivity, and degradability of biomaterials and their effects on wound healing, and provides an overview of artificial dermal scaffold construction strategies based on biomaterials, wound healing cells, and associated cytokines.

Abstract
Background Severe pneumonia is one of the common acute diseases caused by pathogenic bacteria infection, especially by pathogenic bacteria, leading to sepsis with a high morbidity and mortality rate. However, the existing bacteria cultivation method cannot satisfy current clinical needs requiring rapid identification of bacteria strain for antibiotic selection. Therefore, developing a sensitive liquid biopsy system demonstrates the enormous value of detecting pathogenic bacterium species in pneumonia patients. Methods In this study, we developed a tool named Species-Specific Bacterial Detector (SSBD, pronounce as "speed") for detecting selected bacterium. Newly designed diagnostic tools combining specific DNA-tag screened by our algorithm and CRISPR/Cas12a, which were first tested in the lab to confirm the accuracy, followed by validating its specificity and sensitivity via applying on bronchoalveolar lavage fluid (BALF) from pneumonia patients. In the validation I stage, we compared the SSBD results with traditional cultivation results. In the validation II stage, a randomized and controlled clinical trial was completed at the ICU of Nanjing Drum Tower Hospital to evaluate the benefit SSBD brought to the treatment. Results In the validation stage I, 77 BALF samples were tested, and SSBD could identify designated organisms in 4 hours with almost 100% sensitivity and over 87% specific rate. In validation stage II, the SSBD results were obtained in 4 hours, leading to better APACHE II scores (p=0.0035, ANOVA test). Based on the results acquired by SSBD, cultivation results could deviate from the real pathogenic situation with polymicrobial infections. In addition, nosocomial infections were found widely in ICU, which should deserve more attention. Funding National Natural Science Foundation of China.

Abstract
Objective: To explore the level and influencing factors of treatment costs for patients with pneumoconiosis, and to provide a basis for reducing the economic burden of patients with pneumoconiosis and optimizing the rational allocation of medical resources. Methods: In August 2020, the multi-stage stratified sampling method was used to obtain the treatment cost information of pneumoconiosis patients from January to December 2018 in 1123 sample medical institutions. The average cost per time of 2178 outpatients and 7425 inpatients was described, and the differences in the distribution of hospitalization costs for patients with pneumoconiosis were compared by one-way analysis of variance, and a multiple linear regression model was constructed to analyze the influencing factors of hospitalization costs for patients with pneumoconiosis. Results: The average cost of outpatients with pneumoconiosis was 465.88 yuan, and the average cost of inpatients was 12280.63 yuan. There were statistically significant differences in hospitalization expenses among different age, institution level, institution type, length of hospital stay and type of insured (F=10.49, 402.92, 416.35, 2390.48, 1298.14, P<0.001) . Age, length of hospital stay, reimbursement ratio, and institution level were influencing factors of the total hospitalization expenses of patients with pneumoconiosis (t=5.27, 62.20, 22.35, 21.20, P<0.001) . Conclusion: Patients with pneumoconiosis have a heavy burden of treatment costs. Age, length of hospital stay, institution level and reimbursement ratio are the main influencing factors of hospitalization costs. It is recommended to strengthen the prevention and treatment of key populations, standardize the use of medical insurance, and promote the rational allocation of medical resource to reduce the cost burden of pneumoconiosis patients.

Abstract
OBJECTIVE To investigate the populations of freshwater crabs, the intermediate host of Paragonimus and Paragonimus infections in freshwater crabs in the Minjiang River basin along the middle section of Wuyi Mountain, so as to provide baseline data for parasitic disease control and research and expansion of the parasite resource bank. METHODS From November 2020 to April 2021, freshwater crabs were sampled from streams and ditches neighboring residential areas in Jianning County and its neighboring Ninghua, Shaowu, Jiangle and Shunchang counties. The crab species was identified based on the morphological features of the terminal segment of the first abdominal appendage of male crabs, and Paragonimus infections were detected in freshwater crabs. The Paragonimus metacercariae were isolated, and the types of metacercariae were identified based on the metacercaria size, cystic wall thickness, and the excretory bladder and intestinal tract morphology. In addition, the prevalence, intensity and index of metacercaria infections were calculated in freshwater crabs. RESULTS There were seven crab species found in Jianning County and six neighboring water systems along the Minjiang River basin, including Sinopotamon jianglense, S. fukinense, Huananpotamon lichuanense, H. lini, H. shenni, H. planopodum, Bottapotamon engelhardti, and there were metacercariae of three Paragonimus species detected in these crabs, including P. westermani, P. skrjabini and P. sanpingensis, with a prevalence rate of 43.6% (125/287). The infection rates of P. westermani, P. sanpingensis and P. skrjabini were 57.1% (48/84), 26.2% (22/84) and 61.8% (21/34) in S. jianglense, and the infection rates of P. westermani and P. sanpingensis were 52.6% (51/97) and 30.9% (30/97) in S. fukinense, while the rate of P. westermani infection was 6.9% (5/72) in H. lichuanense, which is the first record of P. westermani infections in H. lichuanense. Mixed P. westermani and P. sanpingensis infections were predominantly found in freshwater crabs sampled from Jianning County, where the rate of Paragonimus infections was 70.4% (76/108), with 15.3 metacercariae identified in each crab with Paragonimus infections and 1.9 metacercariae found in each gram of crabs with Paragonimus infections, and the index of metacercariae infections was 20.5. In addition, P. westermani, P. skrjabini and P. sanpingensi metacercariae were found in freshwater crabs sampled from Jianning-neighboring counties, where the rate of Paragonimus infections was 52.3% (56/107), with 9.8 metacercariae identified in each crab with Paragonimus infections and 0.9 metacercariae found in each gram of crabs with Paragonimus infections, and the index of metacercariae infections was 4.6. CONCLUSIONS There are multiple freshwater crab species and Paragonimus infection is high in freshwater crabs in Jianning County and its neighboring Minjiang River basin, which is a high-risk natural focus for Paragonimus infections.

Abstract
Nucleotide-binding leucine-rich-repeat (NLR) genes comprise the largest family of plant disease-resistance genes. Angiosperm NLR genes are phylogenetically divided into the TNL, CNL, and RNL subclasses. NLR copy numbers and subclass composition vary tremendously across angiosperm genomes. However, the evolutionary associations between genomic NLR content and ecological adaptation, or between NLR content and signal transduction components, are poorly characterized because of limited genome availability. In this study, we established an angiosperm NLR atlas (ANNA, https://biobigdata.nju.edu.cn/ANNA/) that includes NLR genes from over 300 angiosperm genomes. Using ANNA, we revealed that NLR copy numbers differ up to 66-fold among closely related species owing to rapid gene loss and gain. Interestingly, NLR contraction was associated with adaptations to aquatic, parasitic, and carnivorous lifestyles. The convergent NLR reduction in aquatic plants resembles the lack of NLR expansion during the long-term evolution of green algae before the colonization of land. A co-evolutionary pattern between NLR subclasses and plant immune pathway components was also identified, suggesting that immune pathway deficiencies may drive TNL loss. Finally, we identified a conserved TNL lineage that may function independently of the EDS1-SAG101-NRG1 module. Collectively, these findings provide new insights into the evolution of NLR genes in the context of ecological adaptation and genome content variation.

Abstract
Objective: To validate the accuracy and consistency of a previously established prediction model for the occurrence of hyperkalemia in non-dialytic chronic kidney disease (CKD) patients. Methods: All patients diagnosed with CKD from Outpatient Department of Shanghai Changzheng Hospital during the 4th quarter of 2020 were recruited. Demographic data, clinical characteristics and prediction model-related parameters of the patients were collected and analyzed. Receiver operating characteristic (ROC) curve was drawn to evaluate the effectiveness of the model, and the specificity and sensitivity were calculated based on the cut-off value of 4 obtained from the previous model. The improved Hanley method was used to compare the area under the curve (AUC) between the previously established model and current validation dataset. The calibration curve was drawn to verify the model calibration degree. Results: A total of 434 patients diagnosed with non-dialytic CKD were enrolled, among whom 233 were males and 201 were females, with an average age of (55±16) years. According to the measured serum potassium values, the prevalence of hyperkalemia was 7.6%. And 33 patients were allocated to the hyperkalemia group and 401 patients were to the normal potassium group. There was no significant difference in age and sex between the two groups (both P>0.05). A combination of hyperkalemia and heart failure (27.3% vs 3.7%, P<0.001), diabetes (42.4% vs 19.7%, P=0.002), and acidosis (51.5% vs 7.0%, P<0.001) were more frequently in the hyperkalemia group, compared with the normal serum potassium group. Patients in the hyperkalemia group were more likely to have a past history of serum potassium ≥5.0 mmol/L (48.5% vs 2.5%, P<0.001). For the drugs that could increase serum potassium levels, there was a significant correlation between Chinese herbal medicine and the occurrence of hyperkalemia, while renin-angiotensin-aldosterone system inhibitor (RAASi) and potassium supplementation showed no significant difference between the two groups. The results of ROC curve analysis showed that the AUC was 0.914, with the sensitivity of 84.8% and the specificity of 79.8% with the cut-off value of 4. The difference of AUC between the previously established risk assessment model of hyperkalemia in patients with non-dialytic CKD and current validation dataset was not statistically significant (Z=1.924, P=0.054), indicating the good accuracy and consistency of the prediction model. In the calibration curve, when the predicted risk of patients was below 0.4 or above 0.6, the prediction effect of the model was better. Conclusion: The previously-constructed hyperkalemia prediction model in non-dialytic CKD patients had good accuracy and consistency, and could be used to evaluate the risk of hyperkalemia in all stages of non-dialytic CKD patients.

Abstract
Objective: To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients. Methods: The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1∶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed. Results: The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively (P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively (P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm(3), the median survival time of SIB and No-SIB group was 34.7 and 30.3 months (P=0.155), respectively. In the patients whose GTV volume>50 cm(3), the median survival time of SIB and No-SIB group was 16.1 and 20.1 months (P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group (P<0.001). Conclusions: The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time.

Abstract
KEY MESSAGE In the soybean variant V94-5152, a BCMV-resistance gene was mapped near to the region of SMV-resistance Rsv4 locus, raising a possibility that V94-5152 may rely on Rsv4 locus to resist against both SMV and BCMV. Both Soybean mosaic virus (SMV) and Bean common mosaic virus (BCMV) can induce soybean mosaic diseases, but few studies have explored soybean resistance against BCMV so far. In this study, V94-5152, a soybean variant resistant to BCMV and SMV, was crossed with a susceptible cultivar, Williams 82 to map the resistance gene. By inoculating 292 F2 individuals with a BCMV isolate HZZB011, a segregation ratio of 3 resistant: 1 susceptible was observed, suggesting that V94-5152 possesses a single-dominant resistance gene against BCMV-HZZB011. Bulk segregation analysis (BSA) then revealed that the resistance gene is closely linked to BARCSOYSSR_02_0617, a simple sequence repeat (SSR) marker on chromosome 2. Genotyping neighboring SSR markers among the 292 F2 individuals enabled us to draw a genetic linkage map, which indicated that the BCMV-resistance gene is located 0.2 cM downstream of BARCSOYSSR_02_0617. Amplification and sequencing ten candidate genes (Glyma02g121300 to Glyma02g122200) around this marker then revealed four genes containing nonsynonymous changes or indels. Also, this location is near to the recently cloned SMV-resistance Rsv4 locus from the cultivar Peking. By obtaining ten more sequences of Rsv4 locus from cultivated and wild soybean materials, we further investigated the variation and evolutionary patterns of this virus-resistance locus. It was evident that positive selections had been acting on this locus, with one critical amino acid change (R55P) shared by all resistance soybeans tested.

Abstract
Lipopolysaccharide (LPS) plays an important role in tumor suppression by activating macrophages. After macrophages activation, a trail of cytokines was secreted, including IL-1β. Previous studies reported that the anti-tumor function of IL-1β is concentration-dependent, and increasing the level of IL-1β will enhance its anti-tumor effect. Cytolysin A (ClyA), a member of the protein family called pore-forming toxins (PFTs), is secreted by Gram-negative bacteria, which has a potential role in enhancing the secretion of IL-1β. In this study, the function of Cytolysin A was evaluated by investigating its ability to induce innate immune responses in macrophages and the signaling pathway(s) involved in LPS-induced production of IL-1β. The production of IL-1β was highly enhanced when the macrophages were treated with LPS and ClyA together. The production of IL-1β was regulated by TLR4-MyD88-IL-1β pathway and NLRP3-ASC-Caspase1-IL1β pathway. By treating the colon cancer cell line CT26 with the conditioned medium, the proliferation of CT26 cells was inhibited and the apoptosis of CT26 cells was increased. In conclusion, this study indicated that ClyA enhances the production of IL-1β induced by LPS in human macrophages. The proliferation of CT26 cells was inhibited and the apoptosis was increased when being treated with the macrophage-conditioned media, which provides a feasible treatment for colon tumor.

Abstract
Objective: To explore the chronic toxicity and its potential mechanism of multi-walled carbon nanotube (MWCNT) in human pleural mesothelial cells. Methods: A sustainable exposure of MeT-5A cells to MWCNT at 10 μg/cm(2) for one year was conducted in 2016. During the exposure, the cell images and cell proliferation was recorded every 4 weeks. The cell apoptosis, cell cycle, cell migration and cell invasion were compared between the control cells and the cells after MWCNT exposure. Finally, the gene expression was screened with Affymetrix clariom D assay, and some of the significantly differential expressed genes was verified by RT-PCR. Results: Compared with the control group, the proliferation ability of the cells in the 1-year exposed group was significantly increased, and the rate of proliferation was about 2-3 times as that in the Control Group (F=481.32, P<0.05) . MeT-5A cells all showed cell cycle arrest effect, which showed the increase of G1 phase and the decrease of s phase and G2 phase (F=14.94, P<0.05) . The apoptosis rate of cells in the treated group was significantly higher than that in the control group after 6 months (F=15.12, P<0.05) , but the early apoptosis rate and the total apoptosis rate of cells in the treated group were not significantly different from those in the control group after 1 year (F=3.97, P<0.05) . The cell migration and invasion were both promoted by MWCNT. Furthermore, the differentially expressed genes was screened, to find 2, 878 genes with more than 2 folds changes. To further verified, RT-PCR was conducted with PIK3R3、WNT2B、VANGL2、ANXA1, and their expression changes were consistent with above. Conclusion: MWCNT might have a carcinogenic potential to MeT-5A cells after the long term exposure.

Abstract
There are many risk factors for gastric cancer (GC), including chronic atrophic gastritis, which involves multiple genes and signaling pathways. Weighted gene co-expression network analysis (WGCNA) was performed on GSE111762 to construct free-scale gene co-expression networks and identified four significant modules that consisted of blue, dark orange, dark red and dark violet. In each module, genes with the most connectivity were selected as hub genes, including G antigen 12J (GAGE12J) in blue, proline, histidine and glycine rich 1 (PHGR1) in dark orange, DNA polymerase gamma 2, accessory subunit (POLG2) in dark red and collagen type XXI alpha 1 chain (COL21A1) in dark violet. The transcription level of COL21A1 and GAGE12J was up-regulated in atrophic gastritis vs normal gastric mucosa, but down-regulated in GC vs atrophic gastritis. PHGR1 was consistently down-regulated from normal gastric mucosa to GC, while POLG2 was up-regulated. Gene set enrichment analysis (GSEA) was then conducted to study the biological functions of hub genes in the development of GC. It showed that multiple tumorigenesis-related pathways were enriched, including peroxisome, DNA repair and KRAS signaling pathway in COL21A1, IL6-JAK-STAT3, epithelial mesenchymal transition (EMT) and TNFα-NF-κB signaling pathway in PHGR1, MYC targets, E2F targets and angiogenesis in POLG2 and peroxisome, Notch signaling pathway and androgen response in GAGE12J. The identified four genes, especially for COL21A1, PHGR1 and POLG2, were important in GC tumorigenesis and affected many cancer-related pathways.

Abstract
Objective: To explore the relationship of early tumor shrinkage (ETS) and depth of response (DpR) with the prognosis and treatment effect of trastuzumab combined with chemotherapy as first-line treatment in advanced gastric cancer with epidermal growth factor receptor 2 (HER-2) positive. Methods: We retrospectively analyzed the clinical and pathological data of 23 patients with metastatic gastric adenocarcinoma diagnosed by imaging in The Second Affiliated Hospital of Zhejiang University School of Medicine from January 1st, 2008 to December 31th, 2017. Kaplan-Meier method and the log-rank test were used for the survival analysis. Cox regression was used to analyze the factors associated with prognosis. Results: The objective response rate (ORR) of the 23 patients was 43.5% and the disease control rate (DCR) was 82.6%. Univariate analysis showed the median progress-free survival (mPFS) of ETS≥20% and ETS<20% were 13.0 months and 4.5 months, respectively, with statistical significance (P<0.001). The median overall survival (mOS) of ETS≥20% and ETS<20% were 26.8 months and 10.1 months, respectively, with statistical significance (P<0.001). The median progress-free survival (mPFS) of DpR≥15% and DpR<15% were 13.0 months and 4.5 months, respectively, with statistical significance (P=0.001). The median overall survival (mOS) of DpR≥15% and DpR<15% were 26.8 months and 9.5 months, respectively, with statistical significance (P<0.001). Multivariable Cox regression analysis revealed ETS was an independent factor of PFS (P=0.030), tumor site and Eastern Cooperative Oncology Group (ECOG) score were independent factors of OS (P<0.05). Conclusion: ETS and DpR might be used to predict the treatment efficacy and prognosis of trastuzumab combined with chemotherapy as the first-line treatment of HER-2 positive gastric cancer.

Abstract
Objective: To evaluate the survival and prognostic factors of radiotherapy in patient with Ⅳ stage esophageal squamous carcinoma treated with radiation or chemoradiation. Methods: The medical records of 608 patients with stage Ⅳ esophageal squamous cell carcinoma who met the inclusion criteria in 10 medical centers in China from 2002 to 2016 were retrospectively analyzed. The overall survival and prognostic factors of all patients at 1, 3 and 5 years were analyzed. Results: The 1-, 3-, 5- year overall survival (OS) rates was 66.7%, 29.5% and 24.3% in stage ⅣA patients, and 58.8%, 29.0% and 23.5% in stage ⅣB patients. There was no statistical difference between the two groups (P=0.255). Univariate analysis demonstrated that the length of lesion, treatment plan, planned tumor target volume (PGTV) dose, subsequent chemotherapy, and degrees of anemia, radiation esophagitis, radiation pneumonia were related to the prognoses of patients with Ⅳ stage esophageal carcinomas after radiotherapy and chemotherapy (P<0.05). Multivariate analysis demonstrated that PGTV dose (OR=0.693, P=0.004), radiation esophagitis (OR=0.867, P=0.038), and radiation pneumonia (OR=1.181, P=0.004) were independent prognostic factors for OS. Conclusions: For patients with stage Ⅳ esophageal squamous cell carcinoma, chemoradiotherapy followed by sequential chemotherapy is recommended, which can extend the total survival and improve the prognosis of the patients. PGTV dose more than 60 Gy has better efficacy.

Abstract
Neutrophilic inflammation occurs during asthma exacerbation, and especially, in patients with steroid-refractory asthma, but the underlying mechanisms are poorly understood. Recently, a significant accumulation of neutrophil extracellular traps (NETs) in the airways of neutrophilic asthma has been documented, suggesting that NETs may play an important role in the pathogenesis. In this study, we firstly demonstrated that NETs could induce human airway epithelial cell damage in vitro. In a mouse asthmatic model of neutrophil-dominated airway inflammation, we found that NETs were markedly increased in bronchoalveolar lavage (BAL), and the formation of NETs exacerbated the airway inflammation. Additionally, a small-molecule drug necrostatin-1 (Nec-1) shown to inhibit NETs formation was found to alleviate the neutrophil-dominated airway inflammation. Nec-1 reduced total protein concentration, myeloperoxidase activity, and the levels of inflammatory cytokines in BAL. Finally, further experiments proved that the inhibition of Nec-1 on NETs formation might be related to its ability to inhibiting mixed lineage kinase domain-like (MLKL) phosphorylation and perforation. Together, these results document that NETs are closely associated with the pathogenesis of neutrophilic asthma and inhibition of the formation of NETs by Nec-1 may be a new therapeutic strategy to ameliorate neutrophil-dominated airway inflammation.

Abstract
Objective: To evaluate the prognostic factors of T1-2N0M0 esophageal squamous cell carcinoma (ESCC) treated with definitive radiotherapy. Methods: The clinical data of 196 patients with T1-2N0M0 ESCC who were treated with definitive radiotherapy in 10 hospitals were retrospectively analyzed. All sites were members of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG). Radiochemotherapy were applied to 78 patients, while the other 118 patients received radiotherapy only. 96 patients were treated with three-dimensional conformal radiotherapy (3DCRT) and 100 treated with intensity-modulated radiotherapy (IMRT). The median dose of plan target volume(PTV) and gross target volume(GTV) were both 60 Gy. The median follow-up time was 59.2 months. Log rank test and Cox regression analysis were used for univariat and multivariate analysis, respectively. Results: The percentage of normal lung receiving at least 20 Gy (V(20)) was (18.65±7.20)%, with average dose of (10.81±42.05) Gy. The percentage of normal heart receiving at least 30 Gy (V(30)) was (14.21±12.28)%. The maximum dose of exposure in spinal cord was (39.65±8.13) Gy. The incidence of radiation pneumonia and radiation esophagitis were 14.80%(29/196) and 65.82%(129/196), respectively. The adverse events were mostly grade 1-2, without grade 4 toxicity. Median overall survival (OS) and progression-free survival (PFS) were 70.1 months and 62.3 months, respectively. The 1-, 3- and 5-year OS rates of all patients were 75.1%、57.4% and 53.2%, respectively. The 1-, 3- and 5-year PFS rates were 75.1%、57.4% and 53.2%, respectively. Multivariate analysis demonstrated that patients'age (HR=1.023, P=0.038) and tumor diameter (HR=1.243, P=0.028)were the independent prognostic factors for OS, while tumor volume were the independent prognostic factor for PFS. Conclusions: Definitive radiotherapy is a promising therapeutic method in patients with T1-2N0M0 ESCC. Patients' age, tumor diameter and tumor volume may impact patients' prognosis.

Abstract
KEY MESSAGE In the soybean cultivar Raiden, both a SMV-resistance gene and a BCMV-resistance gene were fine-mapped to a common region within the Rsv1 complex locus on chromosome 13, in which two CC-NBS-LRR resistance genes (Glyma.13g184800 and Glyma.13g184900) exhibited significant divergence between resistant and susceptible cultivars and were subjected to positive selection. Both Soybean mosaic virus (SMV) and Bean common mosaic virus (BCMV) can induce soybean mosaic diseases. To date, few studies have explored soybean resistance against these two viruses simultaneously. In this work, Raiden, a cultivar resistant to both SMV and BCMV, was crossed with a susceptible cultivar, Williams 82, to fine-map the resistance genes. After inoculating ~ 200 F2 individuals with either SMV (SC6-N) or BCMV (HZZB011), a segregation ratio of 3 resistant:1 susceptible was observed, indicating that for either virus, a single dominant gene confers resistance. Bulk segregation analysis (BSA) revealed that the BCMV-resistance gene is also linked to the SMV-resistance Rsv1 complex locus. Genotyping the F2 individuals with 12 simple sequence repeat (SSR) markers across the Rsv1 complex locus then preliminarily mapped the SMV-resistance gene, Rsv1-r, between SSR markers BARCSOYSSR_13_1075 and BARCSOYSSR_13_1161 and the BCMV-resistance gene between BARCSOYSSR_13_1084 and BARCSOYSSR_13_1115. Furthermore, a population of 1009 F2 individuals was screened with markers BARCSOYSSR_13_1075 and BARCSOYSSR_13_1161, and 32 recombinant F2 individuals were identified. By determining the genotypes of these F2 individuals on multiple internal SSR and single nucleotide polymorphism (SNP) markers and assaying the phenotypes of selected recombinant F2:3 lines, both the SMV- and BCMV-resistance genes were fine-mapped to a common region ( ~ 154.5 kb) between two SNP markers: SNP-38 and SNP-50. Within the mapped region, two CC-NBS-LRR genes exhibited significant divergence between Raiden and Williams 82, and their evolution has been affected by positive selection.

Abstract
Cutaneous melanoma (CM) is a life-threatening form of skin cancer. Prognostic biomarkers can reliably stratify patients at initial melanoma diagnosis according to risk, and may inform clinical decisions. Here, we performed a retrospective, cohort-based study analyzing genome-wide DNA methylation of 461 patients with CM from the TCGA database. Cox regression analyses were conducted to establish a four-DNA methylation signature that was significantly associated with the overall survival (OS) of patients with CM, and that was validated in an independent cohort. Corresponding Kaplan-Meier analysis displayed a distinct separation in OS. The ROC analysis confirmed that the predictive signature performed well. Notably, this signature exhibited much higher predictive accuracy in comparison with known biomarkers. This signature was significantly correlated with immune checkpoint blockade (ICB) immunotherapy-related signatures, and may have potential as a guide for measures of responsiveness to ICB immunotherapy.

Abstract
The NBS-LRR genes are functionally responsible for plant resistance to alien pathogens. Here, we show that NBS-LRR genes originated in the common ancestor of the whole green lineage, and have rapidly diverged into three subclasses with different domain combinations (TNL, CNL, and RNL) before the split of green algae.

Abstract
KEY MESSAGE In the soybean cultivar Suweon 97, BCMV-resistance gene was fine-mapped to a 58.1-kb region co-localizing with the Soybean mosaic virus (SMV)-resistance gene, Rsv1-h raising a possibility that the same gene is utilized against both viral pathogens. Certain soybean cultivars exhibit resistance against soybean mosaic virus (SMV) or bean common mosaic virus (BCMV). Although several SMV-resistance loci have been reported, the understanding of the mechanism underlying BCMV resistance in soybean is limited. Here, by crossing a resistant cultivar Suweon 97 with a susceptible cultivar Williams 82 and inoculating 220 F2 individuals with a BCMV strain (HZZB011), we observed a 3:1 (resistant/susceptible) segregation ratio, suggesting that Suweon 97 possesses a single dominant resistance gene against BCMV. By performing bulked segregant analysis with 186 polymorphic simple sequence repeat (SSR) markers across the genome, the resistance gene was determined to be linked with marker BARSOYSSR_13_1109. Examining the genotypes of nearby SSR markers on all 220 F2 individuals then narrowed down the gene between markers BARSOYSSR_13_1109 and BARSOYSSR_13_1122. Furthermore, 14 previously established F2:3 lines showing crossovers between the two markers were assayed for their phenotypes upon BCMV inoculation. By developing six more SNP (single nucleotide polymorphism) markers, the resistance gene was finally delimited to a 58.1-kb interval flanked by BARSOYSSR_13_1114 and SNP-49. Five genes were annotated in this interval of the Williams 82 genome, including a characteristic coiled-coil nucleotide-binding site-leucine-rich repeat (CC-NBS-LRR, CNL)-type of resistance gene, Glyma13g184800. Coincidentally, the SMV-resistance allele Rsv1-h was previously mapped to almost the same region, thereby suggesting that soybean Suweon 97 likely relies on the same CNL-type R gene to resist both viral pathogens.

Abstract
KEY MESSAGE The divergence patterns of NBS - LRR genes in soybean Rsv3 locus were deciphered and several divergent alleles ( NBS_C, NBS_D and Columbia NBS_E ) were identified as the likely functional candidates of Rsv3. The soybean Rsv3 locus, which confers resistance to the soybean mosaic virus (SMV), has been previously mapped to a region containing five nucleotide binding site-leucine-rich repeats (NBS-LRR) genes (referred to as nbs_A-E) in Williams 82. In resistant cultivars, however, the number of NBS-LRR genes in this region and their divergence from susceptible alleles remain unclear. In the present study, we constructed and screened a bacterial artificial chromosome (BAC) library for an Rsv3-possessing cultivar, Zaoshu 18. Sequencing two positive BAC inserts on the Rsv3 locus revealed that Zaoshu 18 possesses the same gene content and order as Williams 82, but two of the NBS-LRR genes, NBS_C and NBS_D, exhibit distinct features that were not observed in the Williams 82 alleles. Obtaining these NBS-LRR genes from eight additional cultivars demonstrated that the NBS_A-D genes diverged into two different alleles: the nbs_A-D alleles were associated with the rsv3-type cultivars, whereas the NBS_A-D alleles were associated with the Rsv3-possessing cultivars. For the NBS_E gene, the cultivar Columbia possesses an allele (NBS_E) that differed from that in Zaoshu 18 and rsv3-type cultivars (nbs_E). Exchanged fragments were further detected on alleles of the NBS_C-E genes, suggesting that recombination is a major force responsible for allele divergence. Also, the LRR domains of the NBS_C-E genes exhibited extremely strong signals of positive selection. Overall, the divergence patterns of the NBS-LRR genes in Rsv3 locus elucidated by this study indicate that not only NBS_C but also NBS_D and Columbia NBS_E are likely functional alleles that confer resistance to SMV.

Abstract
A microsporidian parasite, Hepatospora eriocheir, is an emerging pathogen for the Chinese mitten crab Eriocheir sinensis. Currently, there is scant information about the way it transmits infection in the crustacean of commercial importance, including its pathogenesis, propagation and infection route in vivo. In this study, chromogenic in situ hybridization (ISH) and quantitative real-time PCR (qPCR) assays were developed to address this pressing need, and we provided an advance in the detection methods available. Pathogens can be seen in situ with associated lesions using ISH. Positive hybridization signals were noted inside the epithelial cells of the hepatopancreas, and putative free parasite spores were observed within the tubule lumen, which were associated with lesions detected by electron microscopy and haematoxylin and eosin (H&E) analysis. qPCR allows the determination of parasite loads in infected tissues, which is important for understanding disease progression and transmission. The hepatopancreas displayed the biggest statistical copy numbers among different tissues of infected crabs, confirming a tissue-specific pathogen infection characteristic. The qPCR assay also proved to be suitable for the diagnosis of asymptomatic carrier crabs. Combination of the two methods could facilitate the study of H. eriocheir infection mechanism in E. sinensis, enhance the early diagnosis of the pathogen and improve the management of microsporidian diseases in commercial crustaceans.

Abstract
Soybean mosaic virus (SMV) is a devastating plant virus classified in the family Potyviridae, and known to infect cultivated soybeans (Glycine max). In this study, seven new SMVs were isolated from wild soybean samples and analyzed by whole-genome sequencing. An updated SMV phylogeny was built with the seven new and 83 known SMV genomic sequences. Results showed that three northeastern SMV isolates were distributed in clade III and IV, while four southern SMVs were grouped together in clade II and all contained a recombinant BCMV fragment (~900 bp) in the upstream part of the genome. This work revealed that wild soybeans in China also act as important SMV hosts and play a role in the transmission and diversity of SMVs.

Abstract
KEY MESSAGE The Rsv1 - h gene in cultivar Suweon 97, which confers resistance to SMVs, was mapped to a 97.5-kb location (29,815,195-29,912,667 bp on chromosome 13) in the Rsv1 locus, thereby providing additional insights into the molecular nature underlying variations in resistance alleles in this particular locus. Soybean mosaic virus (SMV) is a well-known devastating pathogen of soybean (Glycine max (L.) Merrill.) causing significant yield losses and seed quality deterioration. A single dominant allele, Rsv1-h, which confers resistance to multiple SMV strains, was previously reported in the cultivar Suweon 97, but its exact location is unknown. In the present study, Suweon 97 was crossed with a SMV-sensitive cultivar, Williams 82. Inoculating 267 F 2 individuals with two Chinese SMV strains (SC6-N and SC7-N) demonstrated that one single dominant gene confers SMV resistance. Another 1,150 F 2 individuals were then screened for two simple sequence repeat (SSR) markers (BARCSOYSSR_13_1103 and BARCSOYSSR_13_1187) that flank the Rsv1 locus. Seventy-four recombinants were identified and 20 additional polymorphic SSR markers within the Rsv1 region were then employed in genotyping these recombinants. F 2:3 and F 3:4 recombinant lines were also inoculated with SC6-N and SC7-N to determine their phenotypes. The final data revealed that in Suweon 97, the Rsv1-h gene that confers resistance to SC6-N and SC7-N was flanked by BARCSOYSSR_13_1114 and BARCSOYSSR_13_1115, two markers that delimit a 97.5-kb region in the reference Williams 82 genome. In such region, eight genes were present, of which two, Glyma13g184800 and Glyma13g184900, encode the characteristic CC-NBS-LRR type of resistance gene and were considered potential candidates for Rsv1-h.

Abstract
Nucleotide-Binding Site-Leucine-Rich Repeat (NBS-LRR) genes are the largest plant disease resistance (R) gene family, accounting for ∼80% of more than 140 cloned R genes. Recently, we systematically investigated NBS-LRR genes in 22 angiosperm genomes. By performing phylogenetic analysis of these genes in major angiosperm clades separately and as a whole, we gained strong evidence supporting that angiosperm NBS-LRR genes are derived from 3 anciently separated NBS-LRR classes: RPW8-NBS-LRR (RNL), TIR-NBS-LRR (TNL) and CC-NBS-LRR (CNL). A total of 23 ancestral NBS-LRR lineages gave rise to the current NBS-LRR diversity of angiosperm through dynamic expansions. Comparative analysis of RNL, TNL, and CNL classes revealed that while RNL genes evolved conservatively to maintain its role in defense signal transduction, the latter 2 classes underwent convergent recent expansions in various plant genomes. The revealed evolutionary pattern of angiosperm NBS-LRR genes reflects a long history of competition between plant and pathogen.

Abstract
Numerous studies have investigated the relationship between the interleukin-1β gene (IL1B) -511C/T polymorphism and ischemic stroke (IS) risk. However, the results are inconsistent. We performed this meta-analysis of all available case-control studies that evaluated the relationship between the IL1B -511C/T polymorphism and IS. Studies were retrieved from the PubMed and Embase databases. Statistical analyses were conducted using the STATA 11.0 software. Odds ratios (ORs) with 95% confidence intervals (95%CIs) were applied to determine the strength of association. Nine studies comprising a total of 2072 patients and 2173 controls were included. No significant variation in IS risk was detected in any of the genetic models (CC vs TT: OR = 0.78, 95%CI = 0.48-1.27; CT vs TT: OR = 0.83, 95%CI = 0.62-1.10; dominant model: OR = 0.79, 95%CI = 0.55-1.15; recessive model: OR = 0.90, 95%CI = 0.66-1.24). Taking into account the effects of race, further subgroup analyses were performed and our results showed no association between the IL1B gene -511C/T polymorphism and IS in either Asians or Caucasians. No publication bias was found in our study. In conclusion, the IL1B gene -511C/T polymorphism might not be associated with IS risk.

Abstract
Nucleotide-binding site-leucine-rich repeat (NBS-LRR) genes make up the largest plant disease resistance gene family (R genes), with hundreds of copies occurring in individual angiosperm genomes. However, the expansion history of NBS-LRR genes during angiosperm evolution is largely unknown. By identifying more than 6,000 NBS-LRR genes in 22 representative angiosperms and reconstructing their phylogenies, we present a potential framework of NBS-LRR gene evolution in the angiosperm. Three anciently diverged NBS-LRR classes (TNLs, CNLs, and RNLs) were distinguished with unique exon-intron structures and DNA motif sequences. A total of seven ancient TNL, 14 CNL, and two RNL lineages were discovered in the ancestral angiosperm, from which all current NBS-LRR gene repertoires were evolved. A pattern of gradual expansion during the first 100 million years of evolution of the angiosperm clade was observed for CNLs. TNL numbers remained stable during this period but were eventually deleted in three divergent angiosperm lineages. We inferred that an intense expansion of both TNL and CNL genes started from the Cretaceous-Paleogene boundary. Because dramatic environmental changes and an explosion in fungal diversity occurred during this period, the observed expansions of R genes probably reflect convergent adaptive responses of various angiosperm families. An ancient whole-genome duplication event that occurred in an angiosperm ancestor resulted in two RNL lineages, which were conservatively evolved and acted as scaffold proteins for defense signal transduction. Overall, the reconstructed framework of angiosperm NBS-LRR gene evolution in this study may serve as a fundamental reference for better understanding angiosperm NBS-LRR genes.

Abstract
A majority of land plants can form symbiosis with arbuscular mycorrhizal (AM) fungi. MicroRNAs (miRNAs) have been implicated to regulate this process in legumes, but their involvement in non-legume species is largely unknown. In this study, by performing deep sequencing of sRNA libraries in tomato roots and comparing with tomato genome, a total of 700 potential miRNAs were predicted, among them, 187 are known plant miRNAs that have been previously deposited in miRBase. Unlike the profiles in other plants such as rice and Arabidopsis, a large proportion of predicted tomato miRNAs was 24 nt in length. A similar pattern was observed in the potato genome but not in tobacco, indicating a Solanum genus-specific expansion of 24-nt miRNAs. About 40% identified tomato miRNAs showed significantly altered expressions upon Rhizophagus irregularis inoculation, suggesting the potential roles of these novel miRNAs in AM symbiosis. The differential expression of five known and six novel miRNAs were further validated using qPCR analysis. Interestingly, three up-regulated known tomato miRNAs belong to a known miR171 family, a member of which has been reported in Medicago truncatula to regulate AM symbiosis. Thus, the miR171 family likely regulates AM symbiosis conservatively across different plant lineages. More than 1000 genes targeted by potential AM-responsive miRNAs were provided and their roles in AM symbiosis are worth further exploring.

Abstract
Plant genomes harbor dozens to hundreds of nucleotide-binding site-leucine-rich repeat (NBS-LRR) genes; however, the long-term evolutionary history of these resistance genes has not been fully understood. This study focuses on five Brassicaceae genomes and the Carica papaya genome to explore changes in NBS-LRR genes that have taken place in this Rosid II lineage during the past 72 million years. Various numbers of NBS-LRR genes were identified from Arabidopsis lyrata (198), A. thaliana (165), Brassica rapa (204), Capsella rubella (127), Thellungiella salsuginea (88), and C. papaya (51). In each genome, the identified NBS-LRR genes were found to be unevenly distributed among chromosomes and most of them were clustered together. Phylogenetic analysis revealed that, before and after Brassicaceae speciation events, both toll/interleukin-1 receptor-NBS-LRR (TNL) genes and non-toll/interleukin-1 receptor-NBS-LRR (nTNL) genes exhibited a pattern of first expansion and then contraction, suggesting that both subclasses of NBS-LRR genes were responding to pathogen pressures synchronically. Further, by examining the gain/loss of TNL and nTNL genes at different evolutionary nodes, this study revealed that both events often occurred more drastically in TNL genes. Finally, the phylogeny of nTNL genes suggested that this NBS-LRR subclass is composed of two separate ancient gene types: RPW8-NBS-LRR and Coiled-coil-NBS-LRR.

Abstract
A major soybean (Forrest cultivar) quantitative trait locus (QTL) gene, Rhg4, which controls resistance to soybean cyst nematodes (SCN), encodes the enzyme serine hydroxylmethyltransferase (SHMT). The resistant allele possesses two critical missense mutations (P130R and N358Y) compared to that of the sensitive allele, rhg4. To understand the evolutionary history of this gene, sequences of 117 SHMT family members from 18 representative plant species were used to reconstruct their phylogeny. According to this phylogeny, the plant SHMT gene family can be divided into two groups and four subgroups (Ia, Ib, IIa, and IIb). Belonging to the Subgroup Ia lineage, the rhg4 gene evolved from a recent duplication event in Glycine sp.. To further explore how the SCN-resistant allele emerged, both the rhg4 gene and its closest homolog, the rhg4h gene, were isolated from 33 cultivated and 68 wild soybean varieties. The results suggested that after gene duplication, the soybean rhg4 gene accumulated a higher number of non-synonymous mutations than rhg4h. Although a higher number of segregating sites and gene haplotypes were detected in wild soybeans than in cultivars, the SCN-resistant Rhg4 allele (represented by haplotype 4) was not found in wild varieties. Instead, a very similar allele, haplotype 3, was observed in wild soybeans at a frequency of 7.4%, although it lacked the two critical non-synonymous substitutions. Taken together, these findings support that the SCN-resistant Rhg4 allele likely emerged via artificial selection during the soybean domestication process, based on a SCN-sensitive allele inherited from wild soybeans.

Abstract
OBJECTIVE Acanthosis nigricans (AN) is proved to be a skin phenotype of hyperinsulinemia especially in obese patients. Irisin is a new myokine which plays an important role in metabolic disorders, such as obesity, insulin resistance, and type 2 diabetes. The role of irisin in the development of AN-related obesity is not yet understood. In this study, we aimed to investigate the relationship between irisin and AN-related obesity. Patients & Measurements: 30 obese patients without AN (OB group), 30 obese patients with AN (AN group), and 20 age-matched healthy volunteers (control group, CON) were included in this study. Weight, BMI, lipid profile, FFA, UA, and CRP were measured in all participants. Oral Glucose Tolerance tests (OGTT) were performed and serum glucose and plasma insulin were measured at 0, 30, 60,120 and 180 min. The AUC (area under curve) of glucose and insulin was calculated. Serum irisin was measured by ELISA. RESULTS Hyperinsulinemia is found in both AN and OB groups. The AN group had higher levels of insulin but better blood glucose tolerance and insulin response. The difference in irisin levels between the 3 groups was statistically significant, with the AN group showing the highest serum level of irisin. Serum irisin levels were positively correlated with BMI, and fasting insulin. CONCLUSION AN is a state of hyperinsulinmia and has better insulin response and glucose tolerance compared to obese patients without AN. Serum irisin may be a protective factor against impaired beta cell function in obesity with AN.
