Abstract
C57BL/6 mice are frequently utilized as murine models with the desired genetic background for altertion in multiple research contexts. So far, there is still a lack of comprehensive kidney morphology and single-cell transcriptome atlas at all stages of growth of C57BL/6 mice. To provide an interactive set of reference standards for the scientific community, we performed the current study to investigate the kidney's development throughout the capillary-loop stage until senescence. Eight groups, with five to six mice each, represented embryonic stage (embryos 18.5 days), suckling period (1 day after birth), juvenile stage (1 month old), adulthood (containing 3 months old, 6 months old and 10 months old), reproductive senescence stage (20 months old), and post-senescence stage (30 months old), respectively. With age, the thickness of the glomerular basement membrane (GBM) was increased. Notably, GBM knobs appeared at three months and became frequent with age. Using single-cell transcriptome data, we evaluated how various biological process appear in particular cell types and investigated the potential mechanism of formation of GBM konbs. In conclusion, having access to detailed kidney morphology and single-cell transcriptome maps from C57BL/6 mice at various developmental stages of C57BL/6 mice would be a novel and major resource for biological research and testing of prospective therapeutic approaches.

Abstract
The multi-domain protein UHRF1 (ubiquitin-like, containing PHD and RING finger domains, 1) recruits DNMT1 for DNA methylation maintenance during DNA replication. Here, we show that MOF (males absent on the first) acetylates UHRF1 at K670 in the pre-RING linker region, whereas HDAC1 deacetylates UHRF1 at the same site. We also identify that K667 and K668 can also be acetylated by MOF when K670 is mutated. The MOF/HDAC1-mediated acetylation in UHRF1 is cell-cycle regulated and peaks at G1/S phase, in line with the function of UHRF1 in recruiting DNMT1 to maintain DNA methylation. In addition, UHRF1 acetylation significantly enhances its E3 ligase activity. Abolishing UHRF1 acetylation at these sites attenuates UHRF1-mediated H3 ubiquitination, which in turn impairs DNMT1 recruitment and DNA methylation. Taken together, these findings identify MOF as an acetyltransferase for UHRF1 and define a mechanism underlying the regulation of DNA methylation maintenance through MOF-mediated UHRF1 acetylation.

Abstract
Background Glioblastoma (GBM) is an aggressive brain tumor giving a poor prognosis with the current treatment options. The advent of chimeric antigen receptor (CAR) T-cell therapy revolutionized the field of immunotherapy and has provided a new set of therapeutic options for refractory blood cancers. In an effort to apply this therapeutic approach to solid tumors, various immune cell types and CAR constructs are being studied. Notably, macrophages have recently emerged as potential candidates for targeting solid tumors, attributed to their inherent tumor-infiltrating capacity and abundant presence in the tumor microenvironment. Materials and methods In this study, we developed a chemically defined differentiation protocol to generate macrophages from human pluripotent stem cells (hPSCs). A GBM-specific CAR was genetically incorporated into hPSCs to generate CAR hPSC-derived macrophages. Results The CAR hPSC-derived macrophages exhibited potent anticancer activity against GBM cells in vitro. Conclusion Our findings demonstrate the feasibility of generating functional CAR-macrophages from hPSCs for adoptive immunotherapy, thereby opening new avenues for the treatment of solid tumors, particularly GBM.

Abstract
With the development of neoadjuvant therapy and a multidisciplinary team, the treatment of pancreatic cancer has gradually expanded from "resection" to "cure"."Curative resection" as the core part of the integrated treatment model for patients, its quality directly determines the short-term outcome and affects the long-term prognosis. Previously, the "single complication assessment" model was used to measure the quality of pancreatic cancer surgery. However, the incidence of any specific complication cannot cover the entire surgical procedure, making it difficult to quantify and standardize the interpretation of the outcomes. Recently, the concept of textbook outcome, a comprehensive indicator, has gained popularity in surgical research. Textbook outcome includes multiple complication parameters and reflects optimal surgical outcomes in an "all or none" approach. Implementing a quality improvement program that focuses on textbook outcome will increase the overall standard of complex surgery, ultimately advancing the surgical care of pancreatic cancer in the future. In this article, the latest advances in relevant research are analyzed to provide a brief overview of the textbook outcome of pancreatic cancer.

Abstract
OBJECTIVE To investigate the prevalence of comorbid depression and anxiety and to evaluate the effect of psychological interventions among schistosomiasis patients in China, so as to provide insights into improvements of psychological health among schistosomiasis patients. METHODS Publications pertaining to comorbid depression and anxiety and psychological interventions among Chinese schistosomiasis patients were retrieved in electronic databases, including CNKI, Wanfang Data, PubMed, Web of Science, and Embase. The prevalence of comorbidity, psychological interventions, and scores for the Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) before and after psychological interventions among Chinese schistosomiasis patients were extracted. The prevalence of comorbid depression and anxiety was investigated among Chinese schistosomiasis patients using a meta-analysis, and the effect of psychological interventions for depression and anxiety was evaluated. RESULTS A total of 231 publications were retrieved, and 14 publications that met the inclusion and exclusion criteria were included in the final analysis, including 2 English publications and 12 Chinese publications. Meta-analysis showed that the prevalence rates of comorbid depression and anxiety were 61% [95% confidential interval (CI): (48%, 72%)] and 64% [95% CI: (42%, 81%)] among Chinese schistosomiasis patients. Both the SDS [1.45 points, 95% CI: (1.30, 1.60) points] and SAS scores [2.21 points, 95% CI: (2.05, 2.38) points] reduced among Chinese schistosomiasis patients after psychological interventions than before psychological interventions, and the SDS [-0.47 points, 95% CI: (-6.90, -0.25) points] and SAS scores [-1.30 points, 95% CI: (-1.52, -1.09) points] reduced among Chinese schistosomiasis patients in the case group than in the control group. CONCLUSIONS The comorbid anxiety and depression are common among Chinese schistosomiasis patients, and conventional psychological interventions facilitate the improvements of anxiety and depression among schistosomiasis patients.

Abstract
Background The establishment of the anterior-posterior (A-P) axis is a crucial step during tissue repair and regeneration. Despite the association reported recently of N6-methyladenosine (m6A) with regeneration, the mechanism underlying the regulation of m6A in A-P axis specification during regeneration remains unknown. Herein, we deciphered the m6A landscape at a single-base resolution at multiple time points during A-P axis regeneration and constructed the de novo transcriptome assembly of the Dugesia japonica planarian. Results Immunofluorescence staining and comparative analysis revealed that m6A is widespread across the planarian and dynamically regulated during regeneration along the A-P axis, exhibiting a strong spatiotemporal feature. The resulting datasets of m6A-modified genes identified 80 anterior-specific genes and 13 posterior-specific genes, respectively. In addition, we showed that YTHDC1 serves as the primary m6A reader to be involved in the m6A-mediated specification of A-P axis during regeneration in Dugesia japonica planarian. Conclusions Our study provides an RNA epigenetic explanation for the specification of the A-P axis during tissue regeneration in planarian.

Abstract
Mammalian sirtuin 6 (SIRT6) regulates a spectrum of vital biological processes and has long been implicated in the progression of cancer. However, the mechanisms underlying the regulation of SIRT6 in tumorigenesis remain elusive. Here, we report that the tumor-suppressive function of SIRT6 in non-small cell lung cancer (NSCLC) is regulated by acetylation. Specifically, males absent on the first (MOF) acetylates SIRT6 at K128, K160, and K267, resulting in a decreased deacetylase activity of SIRT6 and attenuated SIRT6 tumor-suppressive function in NSCLC. Mechanistically, MOF-mediated SIRT6 acetylation hinders the interaction between SIRT6 and transcriptional factor FOXA2, which in turn leads to the transcriptional activation of ZEB2, thus promoting NSCLC progression. Collectively, these data indicate an acetylation-dependent mechanism that modulates SIRT6 tumor-suppressive function in NSCLC. Our findings suggest that the MOF-SIRT6-ZEB2 axis may represent a promising therapeutic target for the management of NSCLC.

Abstract
Pancreatic surgery is the most complex type of abdominal surgery,with high technical requirements and long learning curve,and the quality of surgery is directly related to the prognosis of the patients. In recent years,more and more indicators have been used to evaluate the quality of pancreatic surgery,such as operation time,intraoperative blood loss,morbidity,mortality, prognosis and so on,and different evaluation systems have been established,including benchmarking,auditing,outcome evaluation based on risk factor adjustment and textbook outcomes. Among them,the benchmark is the most widely used to evaluate surgical quality and is expected to become the standard for comparison among peers. This article reviews existing quality evaluation indicators and benchmarks for pancreatic surgery and anticipates its future application prospects.

Abstract
WTAP, a highly conserved Wilms' tumor 1 interacting protein, is involved in a variety of biological processes. However, functional studies of WTAP in planarians have not been reported. In this study, we examined the spatiotemporal expression pattern of planarian DjWTAP and investigated its functions in planarians regeneration and homeostasis. Knocking-down DjWTAP resulted in severe morphological defects leading to lethality within 20 days. Silencing DjWTAP promoted the proliferation of PiwiA+ cells but impaired the lineage differentiation of epidermal, neural, digestive, and excretory cell types, suggesting a critical role for DjWTAP in stem cell self-renewal and differentiation in planarian. To further investigate the mechanisms underlying the defective differentiation, RNA-seq was employed to determine the transcriptomic alterations upon DjWTAP RNA interference. Histone 4 (H4), Histone-lysine N-methyltransferase-SETMAR like, and TNF receptor-associated factor 6 (TRAF6), were significantly upregulated in response to DjWTAP RNAi. Knocking-down TRAF6 largely rescued the defective tissue homeostasis and regeneration resulted from DjWTAP knockdown in planarians, suggesting that DjWTAP maintains planarian regeneration and homeostasis via TRAF6.

Abstract
The outgrowth of epithelial bud followed by reiterated bifurcations during renal development is driven by the ligand-receptor interactions between the epithelium and the surrounding mesenchyme. Here, by exploring ligand-receptor interactions in E10.5 and E11.5 kidneys by single cell RNA-seq, we find that Isthmin1 (Ism1), a secreted protein, resembles Gdnf expression and modulates kidney branching morphogenesis. Mice deficient for Ism1 exhibit defective ureteric bud bifurcation and impaired metanephric mesenchyme condensation in E11.5 embryos, attributable to the compromised Gdnf/Ret signaling, ultimately leading to renal agenesis and hypoplasia/dysplasia. By HRP-induced proximity labelling, we further identify integrin α8β1 as a receptor of Ism1 in E11.5 kidney and demonstrate that Ism1 promoted cell-cell adhesion through interacting with Integrin α8β1, the receptor whose activation is responsible for Gdnf expression and mesenchyme condensation. Taken together, our work reveals Ism1 as a critical regulator of cell-cell interaction that modulates Gdnf/Ret signaling during early kidney development.

Abstract
Necroptosis plays a double-edged sword role in necroptotic cancer cell death and tumor immune escape. How cancer orchestrates necroptosis with immune escape and tumor progression remains largely unclear. We found that RIP3, the central activator of necroptosis, was methylated by PRMT1 methyltransferase at the amino acid of RIP3 R486 in human and the conserved amino acid R479 in mouse. The methylation of RIP3 by PRMT1 inhibited the interaction of RIP3 with RIP1 to suppress RIP1-RIP3 necrosome complex, thereby blocking RIP3 phosphorylation and necroptosis activation. Moreover, the methylation-deficiency RIP3 mutant promoted necroptosis, immune escape and colon cancer progression due to increasing tumor infiltrated myeloid-derived immune suppressor cells (MDSC), while PRMT1 reverted the immune escape of RIP3 necroptotic colon cancer. Importantly, we generated a RIP3 R486 di-methylation specific antibody (RIP3ADMA). Clinical patient samples analysis revealed that the protein levels of PRMT1 and RIP3ADMA were positively correlated in cancer tissues and both of them predicted the longer patient survival. Our study provides insights into the molecular mechanism of PRMT1-mediated RIP3 methylation in the regulation of necroptosis and colon cancer immunity, as well as reveals PRMT1 and RIP3ADMA as the valuable prognosis markers of colon cancer.

Abstract
Only a small proportion of patients with triple-negative breast cancer benefit from immune checkpoint inhibitor (ICI) targeting PD-1/PD-L1 signaling in combination with chemotherapy. Here, we discovered that therapeutic response to ICI plus paclitaxel was associated with subcellular redistribution of PD-L1. In our immunotherapy cohort of ICI in combination with nab-paclitaxel, tumor samples from responders showed significant distribution of PD-L1 at mitochondria, while non-responders showed increased accumulation of PD-L1 on tumor cell membrane instead of mitochondria. Our results also revealed that the distribution pattern of PD-L1 was regulated by an ATAD3A-PINK1 axis. Mechanistically, PINK1 recruited PD-L1 to mitochondria for degradation via a mitophagy pathway. Importantly, paclitaxel increased ATAD3A expression to disrupt proteostasis of PD-L1 by restraining PINK1-dependent mitophagy. Clinically, patients with tumors exhibiting high expression of ATAD3A detected before the treatment with ICI in combination with paclitaxel had markedly shorter progression-free survival compared with those with ATAD3A-low tumors. Preclinical results further demonstrated that targeting ATAD3A reset a favorable antitumor immune microenvironment and increased the efficacy of combination therapy of ICI plus paclitaxel. In summary, our results indicate that ATAD3A serves not only as a resistant factor for the combination therapy of ICI plus paclitaxel through preventing PD-L1 mitochondrial distribution, but also as a promising target for increasing the therapeutic responses to chemoimmunotherapy.

Abstract
CD47 is a macrophage-specific immune checkpoint protein acting by inhibiting phagocytosis. However, the underlying mechanism maintaining CD47 protein stability in cancer is not clear. Here we show that CD47 undergoes degradation via endocytosis/lysosome pathway. The lysosome protein RAGA interacts with and promotes CD47 lysosome localization and degradation. Disruption of RAGA blocks CD47 degradation, leading to CD47 accumulation, high plasma membrane/intracellular CD47 expression ratio and reduced phagocytic clearance of cancer cells. RAGA deficiency promotes tumor growth due to the accumulation of CD47, which sensitizes the tumor to CD47 blockade. Clinical analysis shows that RAGA and CD47 proteins are negatively correlated in lung adenocarcinoma patient samples. High RAGA protein level is related to longer patient survival. In addition, RAGAhighCD47low patients show the longest overall survival. Our study thereby not only reveals a mechanism by which RAGA regulates CD47 lysosome degradation, but also suggests RAGA is a potential diagnostic biomarker of lung adenocarcinoma.

Abstract
The clinical data of 20 patients with blunt high-grade pancreatic trauma who were admitted to the Department of Hepatobiliary and Pancreatic Surgery of Changhai Hospital Affiliated to Naval Military Medical University from December 2003 to February 2022 were retrospectively analyzed. There were 15 males and 5 females with a median age of 39 years (range: 14-54 years). The degree of pancreatic injury was graded according to the American Association for the Surgery of Trauma (AAST) scale, including 10 cases of grade Ⅲ (50%), 8 cases of grade Ⅳ (40%), and 2 cases of grade Ⅴ (10%). Then, the strategy of diagnosis and treatment for blunt high-grade pancreatic trauma was summarized. The diagnostic rate of CT was 78.9%. Finally, 17 cases (85%) were cured and 3 cases (15%) died. Among the 10 patients with grade Ⅲ pancreatic injury, 7 cases received distal pancreatectomy and splenectomy, 1 case received distal pancreatectomy with spleen preserved, 1 case received pancreatic duct stent placement under endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous catheter drainage (PCD), and 1 case received only PCD. Among 8 cases of grade Ⅳ, 3 cases underwent Roux-en-Y pancreaticojejunostomy, 1 case received distal pancreatectomy and splenectomy, 1 case underwent distal pancreatectomy with spleen preserved, 2 cases received necrotic tissue removal+external drainage of pancreatic duct+abdominal drainage, and 1 case received exploratory laparotomy and gauze packing hemostasis. For 2 cases of grade Ⅴ, 1 underwent pylorus preserving pancreaticoduodenectomy, and the other case underwent pancreaticoduodenectomy combined with right hemicolectomy and splenectomy. Therefore, the treatment of blunt high-grade pancreatic trauma should follow the individualized treatment strategy, pay attention to the control of bleeding, extensive external drainage, appropriate debridement and resection and rational application of damage control surgery, select appropriate patients for conservative treatment, and ultimately benefit the patient.

Abstract
Lamins are the ancient type V intermediate filament proteins contributing to diverse biological functions, such as the maintenance of nuclear morphology, stabilization of chromatin architecture, regulation of cell cycle progression, regulation of spatial-temporal gene expressions, and transduction of mechano-signaling. Deregulation of lamins is associated with abnormal nuclear morphology and chromatin disorganization, leading to a variety of diseases such as laminopathy and premature aging, and might also play a role in cancer. Accumulating evidence indicates that lamins are functionally regulated by post-translational modifications (PTMs) including farnesylation, phosphorylation, acetylation, SUMOylation, methylation, ubiquitination, and O-GlcNAcylation that affect protein stabilization and the association with chromatin or associated proteins. The mechanisms by which these PTMs are modified and the relevant functionality become increasingly appreciated as understanding of these changes provides new insights into the molecular mechanisms underlying the laminopathies concerned and novel strategies for the management. In this review, we discussed a range of lamin PTMs and their roles in both physiological and pathological processes, as well as potential therapeutic strategies by targeting lamin PTMs.

Abstract
Background Mesenchymal stem cells (MSCs) are emerging as the mainstay of regenerative medicine because of their ability to differentiate into multiple cell lineages. The infinite proliferative potential of human pluripotent stem cells (PSCs) grants an unlimited supply of MSCs. Despite their great potential in therapeutic applications, several drawbacks have hindered its clinical translation, including limited number of replication, compromised potential and altered function in late passages. The aim of this study is to establish an efficient method for the production of MSCs from pluripotent stem cells for potential clinical application in rare human disease Hutchinson-Gilford progeria syndrome. Results We established a robust method allowing rapid derivation of MSCs from both human iPSCs and ESCs via a temporal induction of neural ectoderm in chemically defined media. The iPSC- and ESC-derived MSCs satisfy the standard criteria of surface markers. They exhibited a high tri-lineage differentiation potential with over 90% transcriptional similarity to the primary MSCs derived from bone marrow. To evaluate the potential application of this method in disease modeling, MSCs were generated from iPSCs derived from a patient with Hutchinson-Gilford progeria syndrome (HGPS-MSCs) and from mutation-rectified HGPS-iPSCs (cHGPS-MSCs). HGPS-MSCs manifested accelerated senescence whereas mutation rectification rescued cellular senescence in HGPS-MSCs. Conclusions The robust method of MSC derivation from ESCs and iPSCs provides an efficient approach to rapidly generate sufficient MSCs for in vitro disease modeling and clinical applications.

Abstract
Cancer stem-like cells (CSLCs) acquire enhanced immune checkpoint responses to evade immune cell killing and promote tumor progression. Here we showed that signal regulatory protein γ (SIRPγ) determined CSLC properties and immune evasiveness in a small population of lung adenocarcinoma (LUAD) cancer cells. A SIRPγhi population displayed CSLC properties and transmitted the immune escape signal through sustaining CD47 expression in both SIRPγhi and SIRPγlo/– tumor cells. SIRPγ bridged MST1 and PP2A to facilitate MST1 dephosphorylation, resulting in Hippo/YAP activation and leading to cytokine release by CSLCs, which stimulated CD47 expression in LUAD cells and consequently inhibited tumor cell phagocytosis. SIRPγ promoted tumor growth and metastasis in vivo through YAP signaling. Notably, SIRPγ targeting with genetic SIRPγ knockdown or a SIRPγ-neutralizing antibody inhibited CSLC phenotypes and elicited phagocytosis that suppressed tumor growth in vivo. SIRPG was upregulated in human LUAD and its overexpression predicted poor survival outcome. Thus, SIRPγhi cells serve as CSLCs and tumor immune checkpoint–initiating cells, propagating the immune escape signal to the entire cancer cell population. Our study identifies Hippo/YAP signaling as the first mechanism by which SIRPγ is engaged and reveals that targeting SIRPγ represents an immune- and CSLC-targeting strategy for lung cancer therapy.

Abstract
Acute myeloid leukaemia (AML) carrying nucleophosmin (NPM1) mutations has been defined as a distinct entity of acute leukaemia. Despite remarkable improvements in diagnosis and treatment, the long-term outcomes for this entity remain unsatisfactory. Emerging evidence suggests that leukaemia, similar to other malignant diseases, employs various mechanisms to evade killing by immune cells. However, the mechanism of immune escape in NPM1-mutated AML remains unknown. In this study, both serum and leukemic cells from patients with NPM1-mutated AML impaired the immune function of CD8+ T cells in a co-culture system. Mechanistically, leukemic cells secreted miR-19a-3p into the tumour microenvironment (TME) via small extracellular vesicles (sEVs), which was controlled by the NPM1-mutated protein/CCCTC-binding factor (CTCF)/poly (A)-binding protein cytoplasmic 1 (PABPC1) signalling axis. sEV-related miR-19a-3p was internalized by CD8+ T cells and directly repressed the expression of solute-carrier family 6 member 8 (SLC6A8; a creatine-specific transporter) to inhibit creatine import. Decreased creatine levels can reduce ATP production and impair CD8+ T cell immune function, leading to immune escape by leukemic cells. In summary, leukemic cell-derived sEV-related miR-19a-3p confers immunosuppression to CD8+ T cells by targeting SLC6A8-mediated creatine import, indicating that sEV-related miR-19a-3p might be a promising therapeutic target for NPM1-mutated AML.

Abstract
The aim of this study was to investigate the mechanism of interleukin-17 (IL-17) gene in renal tissues of rats suffering from adriamycin (ADM) nephropathy and its effect on the expression level of characteristic proteins, such as Podocalyxin and Nephrin, in podocytes. Sprague-Dawley (SD) rats were randomly divided into a control group (treated with normal saline) and an ADM group (treated with adriamycin). ADM model rats were transfected with lentivirus and divided into a transfection group (transfected with recombinant plasmid IL-17-shRNA) and a negative control group (transfected with plasmid shNC). Coomassie brilliant blue G-250 (CBB) method was adopted to detect the levels of albumin in urine to validate the model. The ultrastructure of rat glomeruli was observed, and the ratio of T helper 17 cells/regulatory T cells (Th17/Treg) was measured by flow cytometry (FCM). The expression levels of IL-17, forkhead box P3 (Foxp3), Nephrin, and Podocalyxin were detected by real-time quantitative PCR (RT-qPCR) and western blot analysis. Results of the study showed that the proteinuria content of the ADM group was significantly higher than that of the control group (P<0.05). In the ADM group, the glomerular basement membrane had uneven thickness and incomplete structure, which showed foot process fusion and electron dense accumulation. However, the glomerular basal membrane in the transfected rats was thin and intact, and a small amount of epithelial foot process fusion and electron density accumulation were observed. The percentages of Th17 cells and IL-17 levels in the ADM group were significantly higher than those in the control group, while the percentages of Treg cells, Foxp3, Nephrin, and Podocalyxin levels were significantly lower than those in the control group (P<0.05). The percentages of Th17 cells, IL-17, Nephrin, and Podocalyxin in the transfection group were significantly higher than those in the ADM group and the negative control group, while the percentages of Treg cells and Foxp3 were significantly lower than those in the ADM group and the negative control group (P<0.05). The results of this study showed that abnormal activation of Th17/IL-17 cells caused podocyte injury and promoted the occurrence and progression of ADM nephropathy. In addition, inhibition of IL-17 gene expression could improve the imbalance of number of Th17 and Treg cells, which may be potentially applied in treatment of patients with primary nephrotic syndrome (PNS).

Abstract
Objective: To evaluate the performance of the European Evidence-based Guidelines on Pancreatic Cystic Neoplasms (EEGPCN)(2018) and International Association of Pancreatology(IAP) Guideline(Version 2017) in predicting high grade dysplasia/invasive carcinoma-intraductal papillary mucinous neoplasm(HGD/INV-IPMN). Methods: A retrospective analysis of 363 patients,who underwent surgical resection in Changhai Hospital affiliated to Navy Medical University from January 2012 to December 2018 and were pathologically identified as (intraductal papillary mucinous neoplasm, IPMN),was performed. The patients,including 230 males and 133 females,aging (61.7±10.1) years(range:19 to 83 years). The proportion of HGD/INV-IPMN who met with the absolute indication(AI) of EEGPCN and high risk stigma(HRS) of IAP were compared. The binary Logistic regression analysis was used to find the independent risk factors of HGD/INV-IPMN.Eight combinations of risk factors derived from relative indication/worrisome feature or risk factors in this study,were made to evaluate the diagnostic efficacy. The area under curve(AUC) of receiver operating characteristics was used to evaluate the the cutoff value of risk factors(①CA19-9≥37 U/ml,②diameter of main pancreatic duct 5.0-9.9 mm,③enhancing mural nodule<5 mm,④(acute) pancreatiti,⑤acyst diameter ≥40 mm,⑤bcyst diameter ≥30 mm, ⑥thickened or enhancing cyst walls,⑦neutrophile granulocyte to lymphocyte ratio(NLR)≥2, ⑧cyst located in head, uncinate or neck,⑨carcinoembryonic antigen(CEA) ≥5 μg/L) number for predicting HGD/INV-IPMN.The accuracy,sensitivity,specificity,positive predictive value,negative predictive value,true positive,true negative,false positive,false negative,positive likelihood ratio,negative likelihood ratio,Youden index and F1 score were calculated. Results: Ninety-two patients(49.5%) of 186 ones who met AI and 85 patients(48.3%) of 176 ones who met HRS were respectively confirmed as HGD/INV-IPMN. In those patients who were not met AI,tumor location,thickened/enhancing cyst wall,CA19-9 elevated,NLR≥2 and CEA elevated were significantly (P<0.05) correlated with HGD/INV-IPMN. And tumor location(head/uncinate/neck vs. body/tail,OR=3.284,95%CI:1.268-8.503,P=0.014),thickened/enhancement cyst wall (with vs.without,OR=2.713,95%CI:1.177-6.252,P=0.019),CA19-9(≥37 U/L vs.<37 U/L, OR=5.086,95%CI:2.05-12.62,P<0.01) and NLR(≥2 vs.<2,OR=2.380,95%CI:1.043-5.434,P=0.039) were the independent risk factors of HGD/INV-IPMN. Patients with ≥4 risk factors of 9 in combination Ⅷ(①②③④⑤b⑥⑦⑧⑨) were diagnosed as HGD/INV-IPMN with the moderate accuracy(71.0%),moderate sensitivity (62.0%) and moderate specificity (73.0%). Patients with ≥4 risk factors of 9 in Combination Ⅶ(①②③④⑤a⑥⑦⑧⑨) were diagnosed as HGD/INV-IPMN with the highest specificity(83.0%) and patients with ≥3 risk factors of 8 in combination Ⅵ(①②③④⑤b⑥⑧⑨) were diagnosed as HGD/INV-IPMN with the highest sensitivity(74.0%). The AUC for diagnosis of HGD/INV-IPMN in combination Ⅵ,Ⅶ and Ⅷ were 0.72,0.75 and 0.75,respectively. Older patients and younger patients could respectively refer to combination Ⅶ and combination Ⅵ to improve the management of IPMN. Conclusions: Patients who meet AI of EEGPCN should undertake resection, otherwise the method we explored is recommended. The method of improvement for diagnosis of HGD/INV-IPMN is relatively applicable and efficient for decision-making of surgery, especially for younger patients with decreasing of missed diagnosis and elder patients with decreasing of misdiagnosis.

Abstract
BACKGROUND The identification of novel targets for recovering sorafenib resistance is pivotal for Hepatocellular carcinoma (HCC) patients. Mitophagy is the programmed degradation of mitochondria, and is likely involved in drug resistance of cancer cells. Here, we identified hyperactivated mitophagy is essential for sorafenib resistance, and the mitophagy core regulator gene ATAD3A (ATPase family AAA domain containing 3A) was down regulated in hypoxia induced resistant HCC cells. Blocking mitophagy may restore the sorafenib sensitivity of these cells and provide a new treatment strategy for HCC patients. METHODS Hypoxia induced sorafenib resistant cancer cells were established by culturing under 1% O2 with increasing drug treatment. RNA sequencing was conducted in transfecting LM3 cells with sh-ATAD3A lentivirus. Subsequent mechanistic studies were performed in HCC cell lines by manipulating ATAD3A expression isogenically where we evaluated drug sensitivity, molecular signaling events. In vivo study, we investigated the combined treatment effect of sorafenib and miR-210-5P antagomir. RESULTS We found a hyperactivated mitophagy regulating by ATAD3A-PINK1/PARKIN axis in hypoxia induced sorafenib resistant HCC cells. Gain- and loss- of ATAD3A were related to hypoxia-induced mitophagy and sorafenib resistance. In addition, ATAD3A is a functional target of miR-210-5p and its oncogenic functions are likely mediated by increased miR-210-5P expression. miR-210-5P was upregulated under hypoxia and participated in regulating sorafenib resistance. In vivo xenograft assay showed that miR-210-5P antagomir combined with sorafenib abrogated the tumorigenic effect of ATAD3A down-regulation in mice. CONCLUSIONS Loss of ATAD3A hyperactivates mitophagy which is a core event in hypoxia induced sorafenib resistance in HCC cells. Targeting miR-210-5P-ATAD3A axis is a novel therapeutic target for sorafenib-resistant HCC.

Abstract
The current studies show that tumor microenvironment of malignant tumor plays critical roles in the tumor progression. The stroma is the main component of tumor microenvironment and the tumor-stroma ratio (TSR) may reflect the relationship of tumor and tumor microenvironment, which has drawn increasing attention from the field of clinical research of cancer.With poor survival,pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease characterized by an intense fibrotic stromal response and the clinical researches related with TSR in PDAC are more significant for patients management compared with that in other tumors.The evaluation methods for TSR are not inconsistent in different studies. But the evaluation result of TSR in pathological method based on whole-mount slide image agrees with that in radiological method, so as the prognosis prediction, that TSR>1 indicated poor prognosis.So TSR can be a stratification marker for patients with PDAC to optimize the tumor stage system used currently. The radiological evaluation before surgery widen the clinical application of TSR in the precise and individual management of patients with PDAC.The comparison for evaluation methods of TSR and the relationship of TSR and prognosis are still needed thorough investigation in ongoing studies with a larger number of patients in multiple centers.

Abstract
Cancer metastasis accounts for the major cause of cancer-related deaths. How disseminated cancer cells cope with hostile microenvironments in secondary site for full-blown metastasis is largely unknown. Here, we show that AMPK (AMP-activated protein kinase), activated in mouse metastasis models, drives pyruvate dehydrogenase complex (PDHc) activation to maintain TCA cycle (tricarboxylic acid cycle) and promotes cancer metastasis by adapting cancer cells to metabolic and oxidative stresses. This AMPK-PDHc axis is activated in advanced breast cancer and predicts poor metastasis-free survival. Mechanistically, AMPK localizes in the mitochondrial matrix and phosphorylates the catalytic alpha subunit of PDHc (PDHA) on two residues S295 and S314, which activates the enzymatic activity of PDHc and alleviates an inhibitory phosphorylation by PDHKs, respectively. Importantly, these phosphorylation events mediate PDHc function in cancer metastasis. Our study reveals that AMPK-mediated PDHA phosphorylation drives PDHc activation and TCA cycle to empower cancer cells adaptation to metastatic microenvironments for metastasis.

Abstract
Lung cancer is one of most common malignant cancer worldwide. It is emerging that PCYT1A, a rate-limiting enzyme required for the biosynthesis of phosphatidylcholine, is associated with cancer progression. However, the biological functions and underlying molecular mechanisms of PCYT1A in lung adenocarcinoma is still unknown. Here we found that PCYT1A suppressed lung adenocarcinoma cancer cell proliferation and migration. Mechanically, PCYT1A served as a novel negative regulator of mTORC1 signaling. PCYT1A knockdown enhanced the malignant proliferation and migration of lung adenocarcinoma cells by activating mTORC1. The promoting effects of PCYT1A silencing on cell proliferation and migration could be abolished when mTORC1 signaling was inhibited by rapamycin or RAPTOR depletion. Importantly, PCYT1A high expression predicted longer survival of lung cancer patients. The expression of PCYT1A was also negatively correlated with mTORC1 activation in the clinical lung cancer samples. We therefore reveal that PCYT1A suppresses proliferation and migration by inhibiting the mTORC1 signaling pathway in lung adenocarcinoma. PCYT1A shows as a potential promising biomarker in lung adenocarcinoma.

Abstract
Areca nut (AN) chewing contributes to an increase of oral squamous cell carcinoma (OSCC) cases in South and Southeast Asia; however, genomic events underlying the carcinogenesis process of AN-related OSCC remain unclear. Here, we comprehensively describe the genomic and transcriptome alterations of 113 Chinese OSCC patients (89 AN related and 24 AN negative) by whole-exome sequencing and RNA sequencing, and we compared the genomic differences between AN-related and AN-negative samples by integrating sequencing data of 325 OSCC patients from The Cancer Genome Atlas database and 50 from a published Taiwanese study. We identified 11 significantly mutated genes for OSCC, including 4 novel ones (ATG2A, WEE1, DST, and TSC2), of which WEE1 and ATG2A mutated with significantly higher rates in AN-related samples (P = 0.04 and P = 0.003, respectively). Mutational signature analysis revealed that AN-related OSCCs were specially characterized by the genomic signature of mismatch repair deficiency (dMMR), which could also predict the prognosis status of AN-related OSCC. In addition, an elevated PD-L1 expression was also observed in both AN-related patients (P = 3.71 × 10-11) and those with a high dMMR level (P = 1.99 × 10-4). Further differential expression analysis and in vitro experiments confirmed the role of dMMR in the development of OSCC induced by AN exposure. Taken together, this study first revealed the molecular profiles and highlighted the role of dMMR in AN-related OSCC among the Chinese population and identified that AN-related OSCC may represent a potential cohort for effective anti-PD-1/L1 immunotherapy.

Abstract
Hydrocephalus is characterized by abnormal accumulation of cerebrospinal fluid (CSF) in the ventricular cavity. The circulation of CSF in brain ventricles is controlled by the coordinated beating of motile cilia at the surface of ependymal cells (ECs). Here, we show that MT1-MMP is highly expressed in olfactory bulb, rostral migratory stream, and the ventricular system. Mice deficient for membrane-type 1-MMP (MT1-MMP) developed typical phenotypes observed in hydrocephalus, such as dome-shaped skulls, dilated ventricles, corpus callosum agenesis, and astrocyte hypertrophy, during the first 2 weeks of postnatal development. MT1-MMP-deficient mice exhibited reduced and disorganized motile cilia with the impaired maturation of ECs, leading to abnormal CSF flow. Consistent with the defects in motile cilia morphogenesis, the expression of promulticiliogenic genes was significantly decreased, with a concomitant hyperactivation of Notch signaling in the walls of lateral ventricles in Mmp14-/- brains. Inhibition of Notch signaling by γ-secretase inhibitor restored ciliogenesis in Mmp14-/- ECs. Taken together, these data suggest that MT1-MMP is required for ciliogenesis and EC maturation through suppression of Notch signaling during early brain development. Our findings indicate that MT1-MMP is critical for early brain development and loss of MT1-MMP activity gives rise to hydrocephalus.

Abstract
Esophageal squamous cell carcinoma (ESCC) is a major subtype of esophageal cancer with high mortality. Previous reports suggested that lncRNA taurine upregulated gene 1 (TUG1) functioned as an oncogene in numerous cancers. The purpose of this study was to explore the potential mechanism of TUG1 carcinogenesis in ESCC. The expression of TUG1 and miR-498 was measured by a quantitative real-time polymerase chain reaction (qRT-PCR). Cell proliferation and apoptosis were assessed by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay and flow cytometry. Cell migration and invasion were identified through the transwell assay. The interaction between miR-498 and TUG1 or X-box binding protein 1 (XBP1) was predicted by bioinformatics software starBase and verified by luciferase reporter assay. The expression of XBP1 was quantified by qRT-PCR and western blot analysis. Xenograft tumor mouse model was established to determine the function of TUG1 in vivo. TUG1 was upregulated in ESCC tissues and cells, and its high expression was associated with tumor lymph node metastasis and low cumulative survival. TUG1 knockdown inhibited proliferation, migration, and invasion but promoted apoptosis in ESCC cells. It was confirmed that miR-498 was a target of TUG1, and XBP1 was a target of miR-498. The expression of miR-498 was reduced in ESCC tissues while XBP1 expression was notably enhanced. Mechanism analysis manifested that TUG1 regulated proliferation, apoptosis, migration, and invasion by upregulating XBP1 via targeting miR-498 in vitro. Furthermore, knockdown of TUG1 attenuated tumor growth in vivo. TUG1 accelerated tumorigenesis and metastasis by inducing XBP1 expression through directly targeting miR-498 in ESCC.

Abstract
Objective: To analyze the wear debris characteristics ofcarbon-based nano- multilayer coatings on Ti(6)Al(4)V alloys and compared with the cobalt chromium molybdenum alloy (CoCrMo) femoral head to evaluate the friction and wear performance of the new coated femoral head. Methods: Three groups were set up in the wear simulation experiment according to the type of femoral head. Group A: imported Cobalt-Chromium-Molybdenum alloy femoral head (CoCrMo); group B: Titanium alloy femoral head (Ti(6)Al(4)V) with carbon-based nano-multilayer coatings; group C: domestic Cobalt-Chromium-Molybdenum alloy femoral head (CoCrMo). All heads were jointed with an ultra-high molecular weight polyethylene (UHMWPE) acetabular cup. Serum samples were collected and stored in the hip joint simulator. After the sample has been digested and diluted, it was filtered through 5 μm, 1.2 μm and 0.4 μm filters, and the filter paper was collected for testing. Scanning electron microscope (SEM) was used to randomly select regions on the filter to obtain images of wear debris. Energy dispersive X-ray spectroscopy (EDS) was used to determine the elemental type of the particle and to eliminate possible contamination. The composition and structure of the abrasive chips were measured using Fourier transform infrared spectrometer (FTIR). The parameters related to the wear debris includingparticle size, shape, number and volume were calculated. The differences in correlation parameters between the groups were compared to evaluate the friction and wear properties of the new coated joints. Results: The main component of the wear debris produced was UHMWPE, and the particle size was mostly below 1 μm. The submicron particle ratio of group B was 49.4%, which was significantly lower than that of the group A and C (75% and 60%, respectively; χ(2)=66.032, 31.754, both P<0.017). The shape was mainly round, and there was no statistical difference between the groups (χ(2)=0.590, P=0.744). The number of particles in group B was significantly less than that of group C on all filters (t=9.960, 8.019, 5.790, all P<0.01), and less than group A on the 0.4 μm filter (t=7.810, P=0.000). Conclusion: The frictional wear performance of the new carbon-based nano-multilayer coatings femoral head is significantly better than that of the domestic femoral head, and even partially exceeds the imported femoral head level, which helps to reduce the production of particles and prevent osteolysis and aseptic loosening induced by UHMWPE particles.

Abstract
Pancreatic cancer is the most lethal malignancy with an overall 5-year survival rate less than 9%, mainly due to late diagnosis and lack of effective therapeutic options.In the last decade, post-operative survival has been enhanced with advent of neoadjuvant therapy and combined adjuvant therapy.Furthermore, the information gained from the omics data, including next generation sequencing data, hasn't yet begun to affect treatment of pancreatic cancer patients.However, in terms of precision medicine, pancreatic cancer has always lagged behind other tumors.Therefore, combined with practical experience, summary of the latest development and research progress of precise medical treatment of pancreatic cancer, especially from the fields of molecular biology and experimental models, is of critical importance. Further development of precise medicine for pancreatic cancer based on platforms using PDX and organoid model would promisingly help in effective improvement of clinical treatment.

Abstract
Objective: To investigate the prognostic factors of hyperamylasemia following pancreaticoduodenectomy (PD) . Methods: Clinical data of 359 patients were collected prospectively who underwent PD by the same group at Changhai Hospital of Navy Medical University from January 2017 to June 2018.There were 212 males and 147 females.The median age was 63 years old (range: 23 to 82 years old) .According to whether the patient's serum amylase was greater than 120 U/L at 0 or 1 day after surgery,the patients were divided into hyperamylasemia group and non-hyperamylasemia group. Univariate analysis and multivariate analysis were used to find out the prognostic factors of hyperamylasemia after PD. Results: Of the 359 patients, 238 cases (66.3%) developed hyperamylasemia.The incidence rate of clinically related pancreatic fistula (15.1% vs.2.5%, P<0.01) , grade B/C post pancreatectomy hemorrhage (8.8% vs. 2.5%, P<0.01) , and surgical site infection (9.2% vs. 3.3%, P=0.04) was significantly higher in the hyperamylasemia group.The severity of complications (CD grade≥Ⅲ: 11.3% vs.4.1%, P=0.023) and postoperative hospital stay (11 days vs. 9 days, P=0.001) were higher in the hyperamylasemia group.In the multivariate analysis, the main pancreatic duct diameter (MPD) ≤3 mm (OR=4.469, 95% CI: 2.563-7.793, P<0.01) , pathological type of disease (pancreatic cancer or pancreatitis) (OR=0.230, 95% CI: 0.122-0.436, P<0.01) and soft texture of pancreas (OR=3.297, 95%CI: 1.930-5.635, P<0.01) were independent prognostic factors for hyperamylasemia. Conclusions: Post-PD hyperamylasemia increased the incidence and severity of postoperative complications after PD.MPD≤3 mm, soft texture of pancreas and pathological type of disease were independent prognostic factors of hyperamylasemia.

Abstract
RLR-mediated type I IFN production plays a pivotal role in elevating host immunity for viral clearance and cancer immune surveillance. Here, we report that glycolysis, which is inactivated during RLR activation, serves as a barrier to impede type I IFN production upon RLR activation. RLR-triggered MAVS-RIG-I recognition hijacks hexokinase binding to MAVS, leading to the impairment of hexokinase mitochondria localization and activation. Lactate serves as a key metabolite responsible for glycolysis-mediated RLR signaling inhibition by directly binding to MAVS transmembrane (TM) domain and preventing MAVS aggregation. Notably, lactate restoration reverses increased IFN production caused by lactate deficiency. Using pharmacological and genetic approaches, we show that lactate reduction by lactate dehydrogenase A (LDHA) inactivation heightens type I IFN production to protect mice from viral infection. Our study establishes a critical role of glycolysis-derived lactate in limiting RLR signaling and identifies MAVS as a direct sensor of lactate, which functions to connect energy metabolism and innate immunity.

Abstract
Mitochondrial pyruvate carrier 1 (MPC1), a key factor that controls pyruvate transportation in the mitochondria, is known to be frequently dysregulated in tumor initiation and progression. However, the clinical relevance and potential molecular mechanisms of MPC1 in lung adenocarcinoma (LAC) progression remain to be illustrated. Herein, MPC1 was lowly expressed in LAC tissues and significantly associated with favorable survival of patients with LAC. Functionally, MPC1 markedly suppressed stemness, invasion, and migration in vitro and spreading growth of LAC cells in vivo. Further study revealed that MPC1 could interact with mitochondrial signal transducer and activator of transcription 3 (mito-STAT3), disrupting the distribution of STAT3 and reducing cytoplasmic signal transducer and activator of transcription 3 (cyto-STAT3) as well as its phosphorylation, while the activation of cyto-STAT3 by IL-6 reversed the attenuated malignant progression in MPC1-overexpression LAC cells. Collectively, we reveal that MPC1/STAT3 axis plays an important role in the progression of LAC, and our work may promote the development of new therapeutic strategies for LAC.

Abstract
In order to predict the livestock carrying capacity in meadow steppe, a method using back propagation neural network is proposed based on the meteorological data and the remote-sensing data of Normalised Difference Vegetation Index. In the proposed method, back propagation neural network was first utilised to build a behavioural model to forecast precipitation during the grass-growing season (June–July–August) from 1961 to 2015. Second, the relationship between precipitation and Normalised Difference Vegetation Index during the grass-growing season from 2000 to 2015 was modelled with the help of back propagation neural network. The prediction results demonstrate that the proposed back propagation neural network-based model is effective in the forecast of precipitation and Normalised Difference Vegetation Index. Thus, an accurate prediction of livestock carrying capacity is achieved based on the proposed back propagation neural network-based model. In short, this work can be used to improve the utilisation of grassland and prevent the occurrence of vegetation degradation by overgrazing in drought years for arid and semiarid grasslands.

Abstract
Because of the high malignancy of pancreatic ductal adenocarcinoma, the cancer-related mortality of pancreatic ductal adenocarcinoma is increasing year by year. Despite advance in surgical techniques, the 5-year survival rate of patients after resection is still less than 30%. Recent studies have found that pancreatic ductal adenocarcinoma is a systemic disease, which may not be cured completely by up-front resection, but requires perioperative multidisciplinary therapy. With the concept of "potentially curable pancreatic cancer" , clinicians need to evaluate the resectability of pancreatic ductal adenocarcinoma accurately before operation, and use the innovative multidisciplinary therapy including neoadjuvant chemoradiotherapy,surgery and adjuvant chemoradiotherapy to improve the R0 resection rate and reduce the risk of early metastasis. Therefore, the therapeutic goal of pancreatic ductal adenocarcinoma is no longer "simple resection" , but long survival through perioperative multidisciplinary treatment. In this article, we briefly introduce the progress of resectability assessment, surgical techniques and perioperative adjuvant therapy of "potentially curable pancreatic cancer" .

Abstract
PI3K/Akt signaling is activated in cancers and governs tumor initiation and progression, but how Akt is activated under diverse stresses is poorly understood. Here we identify AMPK as an essential regulator for Akt activation by various stresses. Surprisingly, AMPK is also activated by growth factor EGF through Ca2+/Calmodulin-dependent kinase and is essential for EGF-mediated Akt activation and biological functions. AMPK phosphorylates Skp2 at S256 and promotes the integrity and E3 ligase activity of Skp2 SCF complex leading to K63-linked ubiquitination and activation of Akt and subsequent oncogenic processes. Importantly, AMPK-mediated Skp2 S256 phosphorylation promotes breast cancer progression in mouse tumor models, correlates with Akt and AMPK activation in breast cancer patients, and predicts poor survival outcomes. Finally, targeting AMPK-mediated Skp2 S256 phosphorylation sensitizes cells to anti-EGF receptor targeted therapy. Our study sheds light on how stress and EGF induce Akt activation and new mechanisms for AMPK-mediated oncogenesis and drug resistance. How Akt pathway is activated under stress is poorly understood. Here, the authors demonstrate the crucial role of AMPK for cellular stresses and growth factors- mediated Akt activation through a mechanism involving the E3 ubiquitin ligase Skp2 and Cullin-1.

Abstract
The century-old embryonal/gametogenesis hypothesis of tumors could link diverse tumors' malignant features together likely representing the real "stemness" of tumors. However, the genetic evidence to validate abnormal gametogenesis in tumors remains lacking. Here we show that p53 deficiency elicits abnormal gametogenesis from primordial germ cell-like stage to late oocyte-like stage and subsequent parthenogenetic activation. The similar upregulation of abnormal gametogenesis by p53 deficiency is observed both in p53-/- mouse model and cultured cancer cells. Notably, germ cell-like cells isolated from distinct tumors from p53-/- mice and cancer cell lines display potent tumorigenicity potential. Abnormal oogenesis induced by p53 deficiency and then spontaneous parthenogenetic activation endow tumors with imitated embryonic development, life cycle, and therapeutic resistance. Our study establishes the genetic evidence to support embryonal/gametogenesis theory of tumors and reveals a pivotal role of p53 in restricting abnormal gametogenesis that may represent a novel aspect for p53's tumor suppression.

Abstract
Genome-wide association studies (GWASs) have achieved great success in deciphering the genetic cause of congenital heart disease (CHD). However, the heritability of CHD remains to be clarified, and numerous genetic factors responsible for occurrence of CHD are yet unclear. In this study, we performed a genome-wide search for relaxed forms of compound heterozygosity (CH) in association with CHD using our existing GWAS data including 2265 individuals (957 CHD cases and 1308 controls). CollapsABEL was used to iteratively test the association between the CH genotype and the CHD phenotype in a sliding window manner. We highlighted 17 genetic loci showing suggestive CH-like associations with CHD (P < 5 × 10-8 ), among which 4 genetic loci had expression quantitative trait loci (eQTL) effects in blood (PeQTL < 0.01). After conditional association analysis, each loci had only 1 independently effective signal reaching the significance threshold (rs2071477/rs3129299 at 6p21.32, P = 2.47 × 10-10 ; rs10773097/rs2880921 at 12q24.31, P = 3.30 × 10-8 ; rs73032040/rs7259476 at 19q13.11, P = 1.14 × 10-8 ; rs10416386/rs4239517 at 19q13.31, P = 1.15 × 10-9 ), together explained 7.83% of the CHD variance. Among these 4 associated loci, outstanding candidates for CHD-associated genes included UBC, CFM2, ZNF302, LYPD3 and CADM4. Although replication studies with larger sample size are warranted, the first CH GWAS of CHD may extend our current knowledge of the genetic contributions to CHD in the Han Chinese population.

Abstract
The dysregulation of transcription factors plays a vital role in tumor initiation and progression. Sex determining region Y-box 5 (SOX5) encodes a member of the SRY-related HMG-box family of transcription factors involved in the determination of the cell fate and the regulation of embryonic development. However, its functional roles in non-small cell lung cancer (NSCLC) remain unclear. Herein, we report that SOX5 sustains stem-like traits and enhances the malignant phenotype of NSCLC cells. We determine that SOX5 is preferentially expressed by cancer stem-like cells (CSLCs) of human NSCLC. In vitro gain- and loss-of-function studies demonstrate that SOX5 promotes self-renewal, invasion and migration in NSCLC cells. Importantly, knockdown of SOX5 potently inhibits tumor growth in a xenograft mouse model. Mechanistically, YAP1 can act as an interacting protein of SOX5 to drive the malignant potential of NSCLC cells. Silencing of YAP1 attenuates the malignant processes in NSCLC cells, which is consistent with the function of SOX5 loss. SOX5 overexpression reverses the attenuated malignant progression in YAP1 knockdown cancer cells. Taken together, these findings identify that SOX5 acts as an oncogenic factor by interacting with YAP1 in NSCLC cells and may be a potential therapeutic target for NSCLC patients.

Abstract
Objective: To compare the clinical therapeutic effects of arterial first approach pancreaticoduodenectomy(AFA-PD) with standard approach pancreaticoduodenectomy(SPD) in the treatment of borderline resectable pancreatic cancer (BRPC). Methods: A retrospective analysis of the clinical data of 113 cases of pancreatic cancer patients from January 2014 to August 2015 at Department of Hepato-Biliary-Pancreatic Surgery, Changhai Hospital, the Second Military Medical University, including 43 cases in AFA-PD group and 70 cases in SPD group.Every patient had gone high-resolusion computed tomography before the surgery, when BRPC was definitely diagnosed by both experienced radiologist and pancreatic surgeon.There were 24 males and 19 females in the AFA-PD group, with average age of (61.6±10.2)years.And in the SPD group, there were 47 males and 23 females, with average age of (62.7±9.4)years. Results: The operation time was (210.7±31.5)minutes in AFA-PD group, (187.9±27.4)minutes in SPD group, and peroperative bleeding volume was (1 007.1±566.3)ml in AFA-PD group, (700.0±390.0)ml in the other group.Those two indicators of AFA-PD group, compared with SPD group, were relatively higher, the difference was statistically significant(all P<0.01). And with regard to postoperative diarrhea(9.3% vs.5.7%), postoperative 1, 3 days of white blood cells(postoperative 1 day: (13.3±1.1)×10(9)/L vs.(12.4±2.4)×10(9)/L; postoperative 3 days: (12.7±1.6)×10(9)/L vs.(11.7±2.5)×10(9)/L), postoperative 1, 3, 5 days of peritoneal drainage fluid volume(postoperative 1 day: (184±42)ml vs.(156±54)ml; postoperative 3 days: (155±48)ml vs.(133±35)ml; postoperative 5 days: (66±20)ml vs.(47±31)ml), the differences between the two groups were statistically significant (all P<0.05). One patient in the SPD group was treated with unplanned secondary surgery for postoperative intraperitoneal hemorrhage, and the patient was cured and discharged.There was no death in the two groups within 30 days after surgical operation and no patient with positive gastric margin, duodenal margin, or anterior margin.The resection rate of superiormesenteric artery(SMA) margin R0 in AFA-PD group was higher than that in SPD group (P=0.019). The two groups were followed up for 14 to 30 months.As for AFA-PD group, the average survival time, progression free survival time and median survival time was respectively (20.4±1.2)months, (21.5±1.4)months and 20 months.There were 3 cases(7.0%) with local recurrence and 8 cases(18.6%) with liver metastasis or distant metastasis.In the SPD group, the average survival time, progression free survival time and median survival time was (17.1±1.1)months, (16.4±1.3)months and 16 months, respectively.There were 13 cases(18.6%) with local recurrence and 25 cases(35.7%) with liver metastasis or distant metastasis.As a result, the AFA-PD group had longer survival time(P=0.001)and progression free survival time(P=0.002). However, the lower local recurrence and distant metastasis rate in AFA-PD group did not reach statistical standard (P>0.05). Conclusion: The arterial first approach pancreaticoduodenectomy is safe and effective in the treatment of borderline resectable pancreatic cancer, which can improve the resection rate of SMA margin R0, and prolong patient survival time.

Abstract
Although deletion of certain autophagy-related genes has been associated with defects in hematopoiesis, it remains unclear whether hyperactivated mitophagy affects the maintenance and differentiation of hematopoietic stem cells (HSCs) and committed progenitor cells. Here we report that targeted deletion of the gene encoding the AAA+-ATPase Atad3a hyperactivated mitophagy in mouse hematopoietic cells. Affected mice showed reduced survival, severely decreased bone-marrow cellularity, erythroid anemia and B cell lymphopenia. Those phenotypes were associated with skewed differentiation of stem and progenitor cells and an enlarged HSC pool. Mechanistically, Atad3a interacted with the mitochondrial channel components Tom40 and Tim23 and served as a bridging factor to facilitate appropriate transportation and processing of the mitophagy protein Pink1. Loss of Atad3a caused accumulation of Pink1 and activated mitophagy. Notably, deletion of Pink1 in Atad3a-deficient mice significantly 'rescued' the mitophagy defect, which resulted in restoration of the progenitor and HSC pools. Our data indicate that Atad3a suppresses Pink1-dependent mitophagy and thereby serves a key role in hematopoietic homeostasis.

Abstract
PURPOSE New strategies are needed for prevention and treatment of chronic lymphocytic thyroiditis (CLT). This study aimed to assess whether combination of levothyroxine treatment and selenium (Se) supplementation results in improved therapeutic effects in CLT compared with levothyroxine monotherapy. METHODS An open-label, randomized controlled study was performed in 60 CLT patients assigned to two groups. Levothyroxine group (LT) patients (n = 24) received levothyroxine alone for 3 months; meanwhile, the combination (LTSS) group (n = 36) was administered levothyroxine with selenium yeast capsule. Blood selenium concentrations, anti-thyroid peroxidase (TPO) and anti-thyroglobulin (Tg) antibody levels, and inflammatory cytokine amounts were compared between both groups before and after treatment. RESULTS At baseline, similar values were obtained in both groups for all the parameters assessed (p > 0.05). After treatment, significantly increased blood selenium levels (µg/L) [90.05 (80.69, 107.76) vs. 39.64 (29.42, 51.10), p < 0.001] and decreased anti-TPO antibody (23.63 ± 9.31 vs. 32.00 ± 10.41%, p = 0.002), anti-Tg antibody (35.84 ± 15.21 vs. 45.47 ± 14.24%, p = 0.015) and IL-2 amounts (pg/mL) [159.29 (124.54, 189.70) vs. 226.48 (190.74, 266.56), p < 0.001] were observed in the LTSS group compared with the LT group post-treatment; meanwhile, similar IL-10 concentrations [23.14 (21.65, 28.56) pg/mL vs. 24.68 (21.71, 29.67) pg/mL] were obtained in both groups. Subgroup analysis of patients with hypothyroidism showed the same trend observed in the whole population; in patients with normal thyroid function, only Se and IL-2 amounts differed between the two treatment groups. Correlation analysis of of the indexes: in HT patients, the basal serum selenium concentration was positively correlated with TT4 (r = 0.294, p < 0.05), significantly negatively correlated with TSH (r = -0.343, p < 0.01), and had no significant correlation with TT3 (p > 0.05). CONCLUSIONS These findings indicated that levothyroxine and selenium combination results in improved therapeutic effects than the levothyroxine monotherapy in preventing CLT progression.
