Abstract
OBJECTIVE To detect the expression of long intergenic non-coding ribonucleic acid (LINC) 01535 in esophageal squamous cell cancer (ESCC) tissues and cells, and to investigate the influences of LINC01535 on the proliferation and apoptosis of ESCC cells and the possible mechanism. PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to determine the relative expression of LINC01535 in 43 cases of ESCC tissues and human esophageal cancer cells (KYSE30, EC9706, TE-13, and Ecal09) compared with human esophageal mucosal epithelial cells (HET-1A). The esophageal cancer cells with the highest expression were selected and transfected with small interfering RNA (si)-LINC01535 (experimental group) or si-negative control (NC) (control group). The interference efficiency was measured via qRT-PCR assay. Regulatory effects of LINC01535 on cell proliferative capacity was examined through colony formation assay and cell proliferation assay [Cell Counting Kit-8 (CCK-8)]. Cell cycle and apoptosis influenced by LINC01535 were detected via flow cytometry. Western blotting was applied to determine the expression changes in the molecular markers of the Janus kinase/signal transducer and activator of transcription 3 (JAK/STAT3) signaling pathway. RESULTS LINC01535 expression in ESCC tissues and cells was remarkably higher than that in para-carcinoma tissues and esophageal mucosal epithelial cells. Knockdown of LINC01535 decreased proliferative capacity, arrested cell cycle in G1/G0 phase, and increased apoptotic rate of ESCC cells. The expressions of the molecular markers of the JAK/STAT3 signaling pathway were altered after knockdown of LINC01535. The above results illustrated that LINC01535 accelerated the proliferation but repressed the apoptosis of ESCC cells by regulating the JAK/STAT3 signaling pathway. CONCLUSIONS The expression of LINC01535 is up-regulated in ESCC tissues and cells, and the highly expressed LINC01535 promotes the proliferation and inhibits the apoptosis of ESCC cells by regulating the JAK/STAT3 signaling pathway. Our findings provide new directions for the diagnosis and treatment of esophageal cancer.

Abstract
Visceral artery aneurysm (VAA) is a rare and potentially life-threatening condition, defined as true artery aneurysms and pseudoaneurysms of splanchnic circulation and renal artery. This study reports our experience in the diagnosis and endovascular treatment of visceral artery aneurysms (VAAs) over a 10-year period. Between 2008 and 2018, a total of 24 VAAs in 21 patients were diagnosed by clinical symptoms and a combination of imaging techniques, such as Doppler ultrasound, computed tomography angiogram, and catheter angiogram. All patients underwent endovascular treatment to exclude aneurysms. Oral antiplatelet medicine was administered, and imaging examination was performed during follow-up. Technical success was achieved in all 21 patients, and no periprocedural complications occurred. Endovascular coiling alone was employed in 10 aneurysms. Coiling was combined with gelfoam in 2 aneurysms. Coiling was assisted by stent in 4 aneurysms. Covered stents were deployed in 8 aneurysms individually. Clinical symptoms disappeared or highly improved in all patients after treatment. None of the patients showed recurrent symptoms after discharge. However, two cases with new aneurysms after 6 and 8 months, respectively, and one case with in-stent thrombosis after 12 months were reported during follow-up. This study may justify the efficacy of percutaneous endovascular coil embolization and stent deployment. It also provides beneficial experience about how to choose appropriate various endovascular strategies based on both clinical symptoms and aneurysm anatomy condition.

Abstract
We have fabricated a Si racetrack optical modulator based on a III-V/Si hybrid metal-oxide-semiconductor (MOS) capacitor. The III-V/Si hybrid MOS optical phase shifter was integrated to a Si racetrack resonator with a coupling length of 200 µm and a coupling gap of 700 nm. The fabricated Si racetrack resonator demonstrated a small VπL of 0.059 Vcm. For 10-dB optical intensity modulation, the Si racetrack resonator showed a 60% smaller driving voltage than a Mach-Zehnder interferometer modulator with the same phase shifter, leading to a better balance between high energy efficiency and large modulation bandwidth.

Abstract
Hemalin, initially described in Haemaphysalis longicornis, is a protein with anticoagulant activity. We retrieved a gene fragment functionally annotated as hemalin from H. flava salivary gland transcriptomic library, but its full-length complementary DNA (cDNA) and antithrombogenicity have not been investigated in the species. Here we cloned the full length of hemalin (Hf-hemalin) by 3'-end rapid-amplification of cDNA ends, and the open reading frame (ORF) of Hf-hemalin was expressed in Escherichia coli. The recombinant protein (rHf-Hemalin) was tested for antithrombogenicity. The full-length of Hf-hemalin was 607 bp with an ORF of423 bp. Protein encoded by Hf-hemalin was predicted to contain 2 Kunitz domains and a signal peptide. The expression of Hf-hemalin in salivary glands, midguts and ovaries was higher in the semi-engorged than the fully engorged. Prokaryotic expression yielded a product of 40 kDa containing a glutathione S-transferase (GST) tag. Incubation of rHf-Hemalin with rat plasma significantly extended prothrombin time and activated partial thromboplastin time compared with normal saline and GST controls. Our data demonstrated that Hemalin from H. flava shared a similar primary structure with that from H. longicornis, and was also anticoagulant. Further investigations are needed to test its feasibility to be an antigen candidate for the development of vaccines against ticks.

Abstract
Objective: To analyze clinical characteristics and monitor microbiome changes in patients with anti-PD-1 associated colitis. Methods: Two patients with non-small cell lung cancer who developed colitis after treated with anti-PD-1 antibodies were retrospectively analyzed in Peking Union Medical College Hospital from January 2019 to January 2020. The clinical symptoms, endoscopic and pathological manifestations, as well microbiome changes were analyzed and compared during pre-treatment, post-treatment and relapse. Results: The main clinical manifestations included diarrhea, elevated inflammatory indicators, colonic mucosal diffuse hyperemic edema with erosion by endoscopy. Changes in the structure of crypts were common pathological characteristics. Glucocorticoids were effective agents, which achieved clinical remission and mucosal healing. The microbiome composition of OTUs was different. After glucocorticoid treatment, the alpha diversity Observed species, Shannon, Simpson, Chao1, ACE indexes all decreased. The Firmicutes decreased with Bacteroidetes increasing in phylum level; while the Bacteroides increased with Ruminococcaceae decreasing in genus level. Lactobacillus was the potentially beneficial genus. Conclusion: Patients developing anti-PD-1 associated colitis have characteristic clinical and pathological manifestations. Glucocorticoids are effective treatment. The fecal microbiome diversity, relative abundance of major phylum and genus have changed after treatment.

Abstract
Objective: To screen out and explore the core gene (Hub gene) involvement and the potential role of cyclin B2 (CCNB2) in the development and prognosis of hepatocellular carcinoma (HCC) through bioinformatics methods. Methods: Four HCC-related datasets were screened, and downloaded from the GEO database. GEO2R tool was used to analyze data and identify the differentially expressed genes (DEGs). Gene Ontology (GO) and KEGG signal pathway enrichment analysis were completed using DAVID database and Cytoscape (ClueGO) plug-in, respectively. Protein-protein interaction network (PPI) of DEGs was established using the STRING database. Cytoscape software was used to visualize PPI network, key modules (cluster) construction and core genes identification. UCSC and UALCAN database were used to analyze the differential expression and survival of TCGA hepatocellular carcinoma core genes. Firebrowse, Oncomine and UALCAN databases were used to analyze the expression of core genes in multiple tumors including HCC. Real-time quantitative reverse transcription PCR (RT-qPCR) was used to detect the expression levels of candidate genes in HCC tissues and liver cancer cell lines. Results: A total of 73 DEGs were identified from the four datasets, including 15 up-regulated genes and 58 down-regulated genes. KEGG pathway enrichment analysis signal showed that DEGs were mainly enriched in tumor-related pathways. PPI network based on DEGs had screened the key modules and 10 core genes. CCNB2 and NCAPG were highly expressed in liver cancer tissues in multiple databases. CCNB2 was positively correlated with NCAPG and was considered as a key gene related to prognosis (P < 0.01). RT-qPCR results showed that CCNB2 was highly expressed in human HCC tissues and cell lines (P < 0.01). Conclusion: Successfully screened DEGs and core genes related to HCC. Among them, CCNB2 is highly expressed in HCC and is related to the survival and prognosis of patients, so it is expected to become a biomarker for the diagnosis and prognosis of HCC.

Abstract
The spatial resolution and imaging characteristics of plastic scintillators are characterized using laser-driven proton beams. Laser-driven proton beams typically have broad energy spectra and are accompanied by relativistic electrons and high-energy photons, both potentially contributing to background noise. Different types and thicknesses of Eljen Technology scintillators are compared to determine their intrinsic point spread function. Point-projection imaging of a mesh is used to compare the imaging resolution of the scintillator to the usual imaging detector, radiochromic film, and is found to be reasonably comparable and sufficient for many experimental applications.

Abstract
Objective: Modeling the immune-related adverse events (irAE) colitis in mice, and explore the protective effect and related mechanism of Lactobacillus rhamnosus GG (LGG) on irAE colitis. Methods: C57BL/6 mice were divided into dextran sodium sulfate (DSS) group (n=3), DSS+anti-programmed death receptor 1 (PD-1) group (n=4), DSS+anti-PD-1+anti-cytotoxic T lymphocyte associated protein 4 (CTLA-4) Group (n=4), DSS+anti-PD-1+anti-CTLA-4+LGG group (n=4), all were given corresponding drugs and probiotics intervention. The severity of colitis were assessed by weight loss, disease activity index (DAI), colon length, colon histopathological score. The inflammatory cytokines and T cell immunity of CD4+, CD8+, FoxP3+regulatory T cells (Treg), were detected by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and immunohistochemical staining respectively. Results: Compared to DSS group, the Day 9 weight [(87.40±1.79)% vs (94.57±0.53)%, P<0.05], colon length [(5.33±0.27)cm vs (6.63±0.12)cm, P<0.05] were lower, and DAI score(2.66±0.24 vs 0.89±0.48), colon histopathological score (12.50±1.04 vs 5.67±0.33), tumor necrosis factor-α (TNF-α) (6.73±1.68 vs 0.91±0.40) (P<0.05), as well CD8+T cells (156.80±8.84 vs 89.00±6.66) and FoxP3+Treg cells (103.80±2.66 vs 48.33±3.18) (P<0.05) were higher in DSS+anti-PD-1+anti-CTLA-4 group. Compared to DSS+anti-PD-1+anti-CTLA-4 group, the DAI score(1.83±0.17 vs 2.66±0.24), colonic histopathology score (8.75±0.63 vs 12.50±1.04), TNF-α level (1.32±0.18 vs 6.73±1.68) (P<0.05) were lower; and CD8+T cells(97.75±3.75 vs 156.80±8.84, P<0.01) level was lower with higher FoxP3+Treg cells (126.00±8.33 vs 103.80±2.66, P=0.046) in DSS+anti-PD-1+anti-CTLA-4+LGG group. Conclusion: DSS combined with anti-PD-1 and anti-CTLA-4 can successfully modeling the irAE colitis in mice, LGG can reduce irAE colitis severity by regulating Treg cells.

Abstract
Objective: To evaluate the clinical effect of three-dimensional (3D) printing individualized titanium mesh for ridge augmentation in the esthetic zone. Methods: Forty-three patients were treated with personalized titanium mesh bone augmentation from Department of Oral Implantology, Stomatological Hospital of Chongqing Medical University from January, 2018 to June, 2020. According to the preoperative cone-beam CT (CBCT) data, the 43 patients [male: 21, female: 22, aged (30.1±5.8) years] were divided into three groups according to the Seibert classification as horizontal, vertical and horizontal-vertical classes (sample size: 14, 15, 14). Then, comprehensively the bone mass and esthetic requirements were taken into account to design and accordingly fabricate the 3D printing individualized titanium mesh. During the surgical process, autologous bone and xenogeneic bone substitutes were mixed at a 1∶1 ratio, combined with injectable platelet-rich fibrin (i-PRF) and individualized titanium mesh for ridge augmentation. All patients were recalled at 1, 3, and 6 months post-operation to observe the mesh exposure; the clinical effect of ridge augmentation was evaluated 6 months post-operation. After the implant placement and final restoration, the pink esthetic score (PES)/white esthetic score (WES) were evaluated. Results: Only one patient experienced early mesh exposure, and no obvious infection was observed. The bone gain regarding three types of bone defects was significantly higher immediately post-operation compared to pre-operation (horizontal, vertical and horizontal-vertical bone defect measured as (3.27±0.13), (17.41±0.46), (3.76±0.24), (14.37±0.89) mm pre-operation, respectively; and (5.25±0.15), (26.10±0.55), (6.35±0.29), (22.52±0.90) mm immediately post-operation, P<0.01). There was no obvious bone resorption 6 months post-operation [outcomes for horizontal, vertical and horizontal-vertical bone defect measured as (5.14±0.14), (25.67±0.52), (6.13±0.26), (22.35±0.89) mm, P>0.05]. The PES/WES scores of all patients were interpreted as "excellent". Conclusions: The 3D printing individualized titanium mesh is effective in repairing bone defects in the esthetic zone, and produces credible esthetic outcomes after implantation and final restoration.

Abstract
Background Chronic kidney disease (CKD) is a common late complication in liver-transplanted patients who have received long-term therapy with calcineurin inhibitors (CNIs). Aims: To analyze kidney disease progression after liver transplantation. Methods We analysed the clinical data of adult single-organ liver transplant recipients performed at our centre between October 2003 and September 2009. The patients with the estimated glomerular filtration rate (eGFR) greater than 60 ml/min/1.73 m2 before surgery were included in the study. Results 69 patients with complete follow-up data were analysed. We found that eGFR at 1 or 2 years after liver transplantation correlated well with eGFR at 5 years. In addition, our results showed that patients whose eGFR declined below 60 at 2 years after liver transplantation would develop an irreversible renal injury in the following years. At 2 years, 12 patients had an eGFR less than 60, which were maintained in 11 patients at 5 years (Sensitivity = 11/12, 91.67%; Specificity = 57/58, 98.28%, Youden's index = 89.95%). The annual rate of eGFR reduction of the tacrolimus group was greater than that of the tacrolimus sparing group based on the value-time variation curve in our study. Moreover, the tacrolimus concentration influenced the CKD progression at 1 and 2 years with an under the ROC curve of 0.73 and 0.78 when Youden's index was at its maximum and the tacrolimus concentrations were 8.55 and 5.96 ng/ml, respectively. Conclusion We confirmed that eGFR at 2 years after liver transplantation is useful for observing a meaningful change in eGFR and renal damage. Obtaining the appropriate serum concentration of an early decrease of the dose of CNIs and transforming non-nephrotoxic immunosuppressants would help improve renal function to prevent CKD progression and end-stage renal disease (ESRD).

Abstract
A pixelated scintillator has been designed, fabricated, and tested using a laser-accelerated proton source for use in proton diagnostics at rep-rated laser facilities. The work presented here demonstrates the enhanced spatial resolution of thin, organic scintillators through a novel pixelation technique. Experimental measurements using laser-generated protons incident onto 130 μm-thick scintillators indicate a >20% reduction in the scintillator point spread function (PSF) for the detectors tested. The best performing pixelated detector reduced the ∼200 μm PSF of the stock material to ∼150 μm. The fabrication technique may be tailored to reduce the pixel size and achieve higher spatial resolutions.

Abstract
AIMS The aims of the study were to (i) improve the evaluation criteria of detoxifying Jatropha curcas L. cake (JCC), (ii) isolate and characterize a JCC tolerant strain, (iii) explore its JCC detoxifying potential. METHODS AND RESULTS The zebrafish was employed as a survival model to screen the strains capable of detoxifying JCC. A strain identified as Mucor circinelloides SCYA25, which is highly capable of degrading all toxic components, was isolated from soil. Different solid-state fermentation parameters were optimized by response surface methodology. The optimal values for inoculation amount, moisture content, temperature, and time were found to be 18% (1·8 × 106 spores g-1 cake), 66%, 26, and 36 days, respectively, to achieve maximum detoxification of the JCC (92%). Under optimal fermentation conditions, the protein content of JCC was increased, while the concentrations of ether extract, crude fiber, toxins, and anti-nutritional substances were all degraded considerably (P < 0·05). Scanning electron microscopy and Fourier transform infrared spectrometer analysis revealed that the fermentation process could disrupt the surface structure and improve the ratio of α-helix to β-folding in the JCC protein, which may improve the digestibility when the detoxified JCC is used as a feedstuff. CONCLUSIONS Our results indicate that M. circinelloides SCYA25 is able to detoxify JCC and improve its nutritional profile, which is beneficial to the safe utilization of JCC as a protein feedstuff. SIGNIFICANCE AND IMPACT OF THE STUDY The newly identified M. circinelloides SCYA25 detoxified JCC in a safe manner to provide a potential alternative to soybean meal for the feed industry. These results also provide a new perspective and method for the toxicity evaluation and utilization of JCC and similar toxic agricultural by-products.

Abstract
RNAscope is a new generation of in situ hybridization technology and with the advantage of new probe design, it is now being gradually applied to a wide range of research fields, and its research scope is constantly expanding. Our country has large number of liver disease patients, so there is a great demand for histological testing and research evaluation based upon biological information. This technology has unique specificity and sensitivity in situ level, which makes up for the technical defects of immunohistochemistry and traditional in situ hybridization. Realizing the multiplicity and monomolecular level detection, the qualitative and quantitative analysis of nucleic acid level can be carried out in many aspects of the field of liver disease, and the visual evaluation can be achieved by combining it with tissue in situ to highlight the value of "gold standard". This article summarizes the recent year's application of RNAscope technology carried out in liver histology field.

Abstract
Liver failure is a rapidly progressive condition with a high mortality rate. Artificial liver treatment is one of the most important treatments for liver failure. In order to ensure the smooth functioning of in vitro circulation device, anticoagulants such as heparin or low-molecular-weight heparin are often used in clinical practice. However, it induces hemorrhage, thrombocytopenia and other adverse reactions, thereby threatening the life safety of liver failure patients. Regional citrate anticoagulation does not affect the coagulation mechanism in vivo, nor does it effects platelets, so in vitro circulating anticoagulants has become the first choice anticoagulant treatment method for continuous renal replacement therapy. Combined with the current research condition at home and abroad, the research progress of the application of regional citrate anticoagulation in artificial liver to treat liver failure is discussed, covering its principle content, application status and application prospect.

Abstract
Uveitis is a serious intra-ocular inflammatory disease that can lead to visual impairment even blindness worldwide. Notch signaling can regulate the differentiation of naive CD4+ T cells, influencing the development of uveitis. DNA methylation is closely related to the autoimmune diseases. In this study, we measured the Notch1 DNA methylation level, determined the Notch1 and related DNA methylases mRNA expression and evaluated the ratio of T helper type 17 regulatory T cell (Th17/Treg ) in peripheral blood mononuclear cells (PBMCs) from uveitis patients and normal control subjects; we also tested the levels of relevant inflammatory cytokines in serum from the participants. Results indicated that compared with those in normal control individuals, the expression of ten-eleven translocation 2 (TET2) and Notch1 mRNA is elevated in uveitis patients, whereas the methylation level in Notch1 DNA promotor region [-842 ~ -646 base pairs (bp)] is down-regulated, and is unrelated to anatomical location. Moreover, the Th17/Treg ratio is up-regulated in PBMCs from uveitis patients, accompanied by the elevated levels of proinflammatory cytokines [e.g. interleukin (IL)-2, IL-6, IL-17 and interferon (IFN)-γ] in serum from uveitis patients. These findings suggest that the over-expression of TET2 DNA demethylase may lead to hypomethylation of Notch1, activate the Notch1 signaling, induce naive CD4+ T cells to differentiate theTh17 subset and thus disturb the balance of the Th17/Treg ratio in uveitis patients. Overall, hypomethylation of Notch1 DNA is closely associated with the occurrence of uveitis. Our study preliminarily reveals the underlying mechanism for the occurrence of uveitis related to the hypomethylation of Notch1 DNA, providing a novel therapeutic strategy against uveitis in clinical practice.

Abstract
Salt marshes contribute to climate change mitigation because of their great capacity to store organic matter (OM) in soils. Most of the research regarding OM turnover in salt marshes in times of global change focuses on effects of rising temperature and accelerated sea-level rise, while effects of land-use change have gained little attention. The present work investigates the mechanisms by which livestock grazing can affect OM decomposition in salt marsh soils. In a grazing exclusion experiment at the mouth of the Yangtze estuary, China, we assessed soil microbial exo-enzyme activity (EEA) to gain insight into the microbial carbon (C) and nitrogen (N) demand. Additionally, we studied the decomposition of plant litter in soil using the Tea Bag Index (TBI), a widely used standardized litter bag assay to fingerprint soil decomposition dynamics. Based on EEAs, grazing markedly reduced microbial C acquisition, whereas microbial N acquisition was strongly increased. These opposing grazing effects were also evident in the decomposition of standardized plant litter: The decomposition rate constant (k) and the stabilization (S) of litter were not inversely related, as would be expected, but instead both were reduced by livestock grazing. Our data suggest that gazing effects on EEAs and litter decomposition can just partly be explained by grazing-driven soil compaction and resulting lower oxygen availability, which has previously been hypothesized as a main pathway by which grazing can reduce microbial activity in wetland soils. Instead, grazing effects on microbial nutrient demand occurs to be an at least equally important control on soil decomposition processes.

It is also important to know the risk factors and prognosis for IgG4-RD patients harboring malignancies.Objectives:To investigate the incidence, related factors and prognosis of IgG4-related disease (IgG4-RD) with malignancies in the Chinese cohort.Table 1.Baseline characteristic of IgG4-RD patients with malignancyPatientSexAgeAge at diagnosis of IgG4-RDAge at diagnosis of malignancySerum IgG4(g/L)Organs involvements of IgG4-RD(*Organ with biopsy)Sites of malignancyP1F5958541499Parotid gland*, salivary glandBreast cancerP2M74666810402Pancreas, bile duct, retroperitoneal fibrosis, kidney, prostate, lymph nodesRectal cancerP3M4642402630Lacrimal gland, parotid glandLipoblastomaP4M7068645780Pancreas, bile duct, lung, prostate, lymph nodesThyroid carcinomaP5F62616111600Pancreas, bile duct, salivary gland*, periaortitis, lymph nodes, pituitaryThyroid carcinomaP6M7268683490Pancreas, bile duct, lymph nodesRectal cancerP7M6058582410Pancreas, bile duct, lymph nodesRenal cancerP8M6863683520Pancreas, bile duct, retroperitoneal fibrosis, lung, kidney, artery, lymph nodesRectal cancerP9M36303512400Pancreas, bile ductSkin cancerP10M52495210000Pancreas, parotid gland*, lacrimal gland, lung, prostate, lymph nodesThyroid carcinomaP11F70686917300Parotid gland, lacrimal gland, salivary gland, sinusLung cancerP12M82797958000Pancreas, lacrimal gland*Colon cancerP13F50494514300Uterus*, ovaryOvarian carcinomaP14F52465010000Parotid gland*, lacrimal glandBreast cancerP15F60555712500Pancreas, parotid gland, lacrimal gland, lymph nodes, sinusLymphomaP16M4237407490Lung*, lymph nodesRenal cancerP17M716869415Pancreas*, bile ductProstate cancerTable 2.Related factors for malignancies in patients with IgG4-RDVariablesUnivariate analysisMultivariate analysisUnivariate OR (95%Cl)P-valueMultivariate OR (95%Cl)P-valueHead and Neck involvement0.304 (0.097- 0.952)0.0410.604 (0.152-2.401)0.474Autoimmune pancreatitis5.359 (1.651-17.393)0.0056.230 (1.559-24.907)0.010Eosinophilia0.117 (0.014-0.966)0.0460.094 (0.010-0.883)0.039Figure 1.Standardized incidence ratios of malignancies in patients with IgG4-RD from different studies.Methods:We prospectively analyzed the IgG4-RD patients recruited in Peking Union Medical College Hospital from January 2011 to August 2018 and identified patients diagnosed with IgG4-RD complicating malignancies. Data regarding demographics, clinical features, treatment and prognosis of IgG4-RD patients complicating malignancies were collected and compared to those of age- and sex-matched controls.Results:Among the 587 Chinese patients with IgG4-RD, 17 malignancies were identified. Ten of them developed malignancy after the diagnosis of IgG4-RD, given a standard incidence ratio (SIR) of 2.78 (95%CI 1.33-5.12). Multivariate logistic analysis indicated that autoimmune pancreatitis (OR= 6.230, 95%CI 1.559-24.907, p=0.010) was positively associated with malignancy, whereas eosinophilia (OR= 0.094, 95%CI 0.010-0.883, p=0.039) was negatively related with malignancies. During a median follow-up period of 61.4±26.4 months, all patients with IgG4-RD and malignancies survived.Conclusion:An increased incidence of malignancy was found in Chinese IgG4-RD cohort. Autoimmune pancreatitis is a potential risk factor, whereas eosinophilia is a possible protective factor for complicating malignancies.References:[1] Wallace, Z. S.,et al.

Abstract
Objective: To explore peptidomic changes of peptides in saliva and gingival crevicular fluid (GCF) before and after treatment of gingivitis. Methods: From January 2017 to September 2017, seventeen participants at the age of 24-62 (6 males and 11 females) at Department of Preventive Dentistry, Peking University School and Hospital of Stomatology with gingivitis were recruited in the present study. Their clinical parameters were measured and recorded. Saliva and GCF samples were collected from each of the participants at the baseline and 7 days after ultrasonic supragingival scaling, respectively. Matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS) was employed to detect the changes of peptidomic profiles, while ano-liquid chromatography-electrospray ionization-tandem mass spectrometry (nano-LC/ESI-MS/MS) was performed to identify the possible proteins from which the peptides might derive. Results: Initially, four peptide peaks [mass-to-charge ratio (m/z) values: 1 030.6, 1 043.4, 1 053.4 and 1 064.6] were screened out exhibiting a decreasing trend after treatment (P<0.05). Besides, five peptide peaks from gingival crevicular fluid (P<0.05) exhibited differential expression, among which 1 055.5 and 1 168.3 demonstrating a decrease after treatment, while 3 363.7, 3 480.9 and 3 489.5 increased overtime. Certain positive correlations were detected between some peptides and clinical parameters. Principle component analysis using the above mentioned peptide peaks showed a distinct distribution before and after treatment and peptides from GCF showed a slightly better capacity to discriminate patients before and after treatment. The peptides with m/z values of 1 055.5 in GCF and 1 064.6 in saliva were identified to be segments of serum albumin and complement C3, respectively. Conclusions: Several differentially expressed peptides were detected in saliva and GCF by MALDI-TOF MS, exhibiting the potentiality to act as biomarkers in gingivitis patients.

Abstract
OBJECTIVE An increasing number of reports have shown that microRNAs (miRNAs) play a vital role in the occurrence and development of cancer by acting as tumor inhibitors or oncogenes. The purpose of this research was to explore whether the expression level of microRNA-15a-5p (miR-15a-5p) was related to TP53 regulated inhibitor of apoptosis 1 (TP53INP1) in cervical cancer, and to explore the role of miR-15a-5p in cervical cancer in vitro. PATIENTS AND METHODS Human cervical cancer tissues and adjacent normal tissues were obtained from 30 cervical cancer patients. Firstly, we carried out the quantitative Real Time-PCR (qRT-PCR) assay to evaluate the level of miR-15a-5p in cervical cancer tissues and cell lines. The TargetScan and the Dual-Luciferase Reporter Assay were used to confirm the relationship between TP53INP1 and miR-15a-5p. Besides, the Cell Counting Kit-8 (CCK-8) and the flow cytometry analysis were performed to detect the effect of miR-15a-5p on cell proliferation and apoptosis in cervical cancer cells. RESULTS Our results showed that the expression of miR-15a-5p was enhanced in cervical cancer tissues and cells lines. The data from the Dual-Luciferase Reporter Assay demonstrated that TP53INP1 was a direct target of miR-15a-5p. We also found that TP53INP1 was down-regulated in the cervical cancer tissues and cell lines compared with the adjacent normal tissues and normal cervical cells. Besides, the down-regulation of miR-15a-5p depressed cervical cancer cell proliferation and enhanced cell apoptosis. Our results clearly suggested that the down-regulation of TP53INP1 successfully impaired the tumor-inhibition effects of miR-15a-5p inhibitor in cervical cancer cells. CONCLUSIONS Our findings indicated that miR-15a-5p functioned as a tumor-promoting gene in cervical cancer by directly targeting TP53INP1, indicating that miR-15a-5p might be a potential treatment target for cervical cancer patients.

Abstract
Hepatitis B virus (HBV)/hepatitis C virus (HCV) co-infection shares the same transmission routes, and thereby it is not rare in regions where the prevalence of HBV and HCV is high. However, the co-infection rates of HBV/HCV reported in different regions of the world are relatively dissimilar, and the co-infection rates of HBV/HCV in the population are unidentified due to the presence of silent HBV infection. Thus, the phenomenon of underestimation exists. HCV may have an inhibitory effect on HBV replication when HBV/HCV is co-infected, and the effect of HBV on HCV replication remains to be certain by more studies. Furthermore, the mechanism of interaction may include the direct effect of viral proteins and the indirect effect of immune mediated host response. HBV/HCV co-infection can cause more serious chronic liver diseases and cirrhosis, and can increase the risk of liver cancer. The efficacy of peginterferon plus ribavirin in patients with HBV/HCV co-infection is same as HCV monotherapy. There are few studies on the efficacy of direct-acting antiviral drugs. Patients with HBV/HCV co-infection have the risk of HBV reactivation regardless of anti-HCV treatment with peginterferon plus ribavirin or direct-acting antiviral drugs, but the probability of HBV reactivation and how to assess and prevent it needs more studies to interpret.

Abstract
BACKGROUND Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a severe allergic condition in which wheat ingestion together followed by physical exercise induces anaphylaxis. For patients with WDEIA, omega-5 gliadin is considered to be one of the major allergens. AIM To analyse the clinical features and allergen spectrum of WDEIA and to investigate the relationship between WDEIA and serum levels of platelet-activating factor (PAF), interleukin (IL)-9 and IL-33. METHODS Medical histories and conditions of WDEIA cases were collected and summarized, with allergen tests of wheat proteins measured at the same visit. Of the 33 patients enrolled, 13 also had serum levels of PAF, IL-9 and IL-33 measured. The healthy control (HC) group consisted of 13 healthy individuals, who also underwent both the wheat-protein allergen tests and the inflammatory-mediator tests. RESULTS All patients experienced severe allergic reaction during exercise after wheat ingestion. Manifestations of WDEIA included facial oedema, generalized urticaria and respiratory symptoms. Unconsciousness was also observed in 21 cases. In the patient group, 57.6% were confirmed as hypersensitive to glyceraldehyde-3-phosphate dehydrogenase (GAPDH), while 54.5% were allergic to omega-5 gliadin. PAF concentration was significantly higher in patients with WDEIA compared with HCs, whereas there was no significant difference in IL-9 or IL-33 between the two groups. CONCLUSIONS WDEIA is a rare type of anaphylaxis. GAPDH and omega-5 gliadin may be the most common allergy-causing wheat proteins for Chinese people. PAF may be associated with the onset and development of WDEIA.

Abstract
AIMS Patients with renovascular hypertension (RVH) exhibit elevated urinary mtDNA copy numbers, considered to constitute surrogate markers of renal mitochondrial injury. The modest success of percutaneous transluminal renal angioplasty (PTRA) in restoring renal function in RVH has been postulated to be partly attributable to acute reperfusion injury. We hypothesized that mitoprotection during revascularization would ameliorate PTRA-induced renal mitochondrial injury, reflected in elevated urinary mtDNA copy numbers and improve blood pressure and functional outcomes 3 months later. METHODS We prospectively measured urinary copy number of the mtDNA genes COX3 and ND1 using qPCR in RVH patients before and 24 hrs after PTRA, performed during IV infusion of vehicle (n = 8) or the mitoprotective drug elamipretide (ELAM, 0.05 mg/kg/h, n = 6). Five healthy volunteers (HV) served as controls. Urinary mtDNA levels were also assessed in RVH and normal pigs (n = 7 each), in which renal mitochondrial structure and density were studied ex-vivo. RESULTS Baseline urinary mtDNA levels were elevated in all RVH patients vs HV and directly correlated with serum creatinine levels. An increase in urinary mtDNA 24 hours after PTRA was blunted in PTRA+ELAM vs PTRA+Placebo. Furthermore, 3-months after PTRA, systolic blood pressure decreased and estimated glomerular filtration rate increased only in ELAM-treated subjects. In RVH pigs, mitochondrial damage was observed using electron microscopy in tubular cells and elevated urinary mtDNA levels correlated inversely with renal mitochondrial density. CONCLUSIONS PTRA leads to an acute rise in urinary mtDNA, reflecting renal mitochondrial injury that in turn inhibits renal recovery. Mitoprotection might minimize PTRA-associated mitochondrial injury and improve renal outcomes after revascularization.

Abstract
BACKGROUND Primary erythromelalgia (PE) is a dominant inherited disorder characterized by recurrent pain, redness, and warmth of the extremities that is caused by gain-of-function mutations in Nav1.7 encoding gene SCN9A. Most of the PE-causing mutations of Nav1.7 have been shown to be able to render Nav1.7-expressing cells hyperexcitable, however in most PE cases the symptoms are refractory to treatment with sodium channel blockers and the mechanism underlying the intractability has not been clearly clarified. OBJECTIVE To identify the mutation of SCN9A in a Chinese Han family with typical symptoms of PE and study the electrophysiological effect of the identified mutation. METHODS A Chinese Han family with typical symptoms of PE was collected and the proband's response to treatment was recorded. All the exons and flanking intronic sequences of SCN9A were amplified with PCR and sequenced. Several online programs were used to predict the damaging effect of variants. The functional effect of variants was studied by voltage-clamp analysis in CHO-K1 cells. RESULTS The PE symptoms of the proband are refractory to all kinds of reported medications. Sequence analysis of SCN9A showed that a novel c.2477T>A (p. F826Y) mutation co-segregated with the disease phenotype. Several online programs predicted that the F826Y mutation has a deleterious effect on the gene product. Voltage-clamp analysis showed that while compared with the wild-type channel, activation of the F826Y mutant channel was shifted by 7.7 mV in a hyperpolarizing direction, whereas steadystate inactivation was shifted by 4.3 mV in a depolarizing direction. CONCLUSION A novel disease-causing SCN9A Mutation (F826Y) was identified in a Chinese family with typical PE symptoms refractory to treatment. F826Y of Nav1.7 could render DRG neurons hyperexcitable, contributing to the pathogenesis of PE.

Abstract
One of the end-products of ROS-induced peroxidation, malondialdehyde (MDA), induces the cross-links in proteins, which leads to perturbation of the physiological functions of cells and contributes to abnormal biological regulation and various disorders. Taurine (2-aminoethanesulfonic acid, Tau) aids in adjusting normal physiological functions to confer stress resistance. The protective effects of Tau against MDA stress in vitro or in vivo were reported previously. In this study, we had investigated the protective effects of taurine on viability, oxidative stress levels and mitochondrial biogenesis in mouse muscle C2C12 cells undergoing MDA induced stress. We show that the treatment with 100 μM MDA leads to increase in cell oxidative stress levels, inhibition of mitochondrial biogenesis and the reduction of the cell survival rates. The pretreatment with 0.1 μM taurine reduced MDA-induced death rate via inhibition of oxidative stress, restoration of mitochondrial functions of the mitochondrial membrane potential (MMP) and ATP production. In MDA stress, the pre-treatment with 0.1 μM taurine leads to upregulation of the factors of mitochondrial biogenesis. These observations suggest that the cytoprotective effects of taurine may be due to an induction of mitochondrial biogenesis.

Abstract
Objective: To evaluate the efficacy and safety of Vesselplasty in the treatment of osteoporotic vertebral fractures and vertebral metastases. Methods: From June 2010 to December 2016, data of 81 patients with spinal diseases treated with Vesselplasty in Department of Spinal Surgery, Beijing Friendship hospital, Capital Medical University were retrospectively analyzed. There are 49 cases of vertebral fractures with age (70.2±8.2) years. Among them, 16 cases have posterior vertebral wall breakage, but no symptoms of nerve injury. Clinical result were evaluated with Visual Analogue Scale(VAS) , the kyphotic angle(Cobb's angle) and Oswestry disability index(ODI) was measured preoperatively, postoperatively and follow-up. At the same time, the operation time and cement leakage were recorded. There were 32 patients with vertebral metastases, with age of (69.6±11.1) years old. The posterior wall of the vertebral body was damaged in 22 cases. The VAS scores were recorded and compared preoperatively and postoperatively. The operation time was recorded also. Results: All patients were completed the operation safely and with no complications. Compared with preoperative VAS, postoperative VAS was significantly decreased in all subjects(P<0.05). The average operation time of each vertebral body was 16.2±4.6 min, and the postoperative VAS score significantly decreased (P<0.05), Cobb 's angle from preoperative (13.9±6.0) ° to( 5.2±4.0) ° (P<0.05) in 49 cases of vertebral fracture(58 vertebrae). The clinical results were still satisfied in follow-up . In 32 cases of vertebral metastases(38 vertebrae), the average operation time was (17.6±5.4) min. The postoperative VAS score was obviously decreased also(P<0.05). A small amount of bone cement leakage occurred in 4 cases of 4 vertebrae. The rate of bone cement leakage was 4.2%, but there were no clinical symptoms in these cases. Conclusion: Vesselplasty is a safe and effective treatment of osteoporotic vertebral fractures and vertebral metastases. It can lead to satisfactory clinical effect, partial recovery of vertebral height. Besides, the bone filling mesh can reduce the risk of bone cement leakage, which can provide a new choice for minimally invasive treatment of vertebral fracture and metastases.

Abstract
Objective: To characterize the relations between the practice of parenting and associated factors on children (0-5 years old) in urban areas of China, in order to provide evidence for promoting the early development of children and to provide positive guidance and service programs on parenting. Methods: A total of 4 515 parents from 15 cities (14 provinces) were surveyed with a self-administered questionnaire. Parenting and Family Adjustment Scales (PAFAS) was used, including parameters as: consistency and coercive parenting, positive encouragement, parent-child relationship and parental emotion adjustment, family relationship and parental teamwork aspects, etc. Both single factor analysis and multiple linear regression were used to examine the associations between parenting practice, individual, parental and family factors. Results: The mean score of PAFAS was 21.00 (15.00-28.00), associated with factors as children's age, only-child family, premature delivery, father's education level, confidence on parenting, problems regarding the parental mood, annual family income, family structure and behavior on seeking professional help, etc. Results showed that there were big differences on the practice of parenting in China and influenced by variety of factors. Conclusions: The general situation of parenting was well, in the urban areas of China. The practice of parenting was associated with a series of individual, parental and family factors. Programs on improving the parenting skills and promoting the early development of children, should be highlighted.

Abstract
Objective: To investigate the clinical effect and safety of long-acting pegylated interferon-α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 μg/week) in the treatment of HBeAg-positive chronic hepatitis B (CHB) patients, with standard-dose Peg-IFN-α-2a as positive control. Methods: This study was a multicenter, randomized, open-label, and positive-controlled phase III clinical trial. Eligible HBeAg-positive CHB patients were screened out and randomized to Peg-IFN-α-2b (Y shape, 40 kD) trial group and Peg-IFN-α-2a control group at a ratio of 2:1. The course of treatment was 48 weeks and the patients were followed up for 24 weeks after drug withdrawal. Plasma samples were collected at screening, baseline, and 12, 24, 36, 48, 60, and 72 weeks for centralized detection. COBAS® Ampliprep/COBAS® TaqMan® HBV Test was used to measure HBV DNA level by quantitative real-time PCR. Electrochemiluminescence immunoassay with Elecsys kit was used to measure HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe). Adverse events were recorded in detail. The primary outcome measure was HBeAg seroconversion rate after the 24-week follow-up, and non-inferiority was also tested. The difference in HBeAg seroconversion rate after treatment between the trial group and the control group and two-sided confidence interval (CI) were calculated, and non-inferiority was demonstrated if the lower limit of 95% CI was > -10%. The t-test, chi-square test, or rank sum test was used according to the types and features of data. Results: A total of 855 HBeAg-positive CHB patients were enrolled and 820 of them received treatment (538 in the trial group and 282 in the control group). The data of the full analysis set showed that HBeAg seroconversion rate at week 72 was 27.32% in the trial group and 22.70% in the control group with a rate difference of 4.63% (95% CI -1.54% to 10.80%, P = 0.1493). The data of the per-protocol set showed that HBeAg seroconversion rate at week 72 was 30.75% in the trial group and 27.14% in the control group with a rate difference of 3.61% (95% CI -3.87% to 11.09%, P = 0.3436). 95% CI met the non-inferiority criteria, and the trial group was non-inferior to the control group. The two groups had similar incidence rates of adverse events, serious adverse events, and common adverse events. Conclusion: In Peg-IFN-α regimen for HBeAg-positive CHB patients, the new drug Peg-IFN-α-2b (Y shape, 40 kD) has comparable effect and safety to the control drug Peg-IFN-α-2a.

Abstract
Objective: To modify the individual neuroendoscopic surgical approach of pituitary tumors with specific imaging features, and to analyze the clinical outcomes. Methods: The clinical data of 116 patients with pituitary tumors who underwent surgical treatment at the pituitary tumor diagnosis and treatment center of Ruijin Hospital from April 2014 to December 2017 were collected, then the resection effects and complication rates of pituitary tumors from three different kinds of transsphenoidal approaches (e.g. classical single nostril approach, bilateral approach, "one-and-a-half" approach) were compared. Results: Pituitary tumor resection with "one-and-a-half" trans-nasal-sphenoidal approach achieved the same surgical effects with the bilateral approach, which was difficult to resect with the single-nostril classical approach. And it had significant advantages in the average length of postoperative hospitalization ( "one-and-a-half" : 6.9 days, bilateral: 12.5 days, P<0.01), the average postoperation VAS of olfactory retention ( "one-and-a-half" : 8.6, bilateral: 7.0, P<0.01) and preventing posterior nasal septum perforation (the occurrence rate of "one-and-a-half" : 0%, bilateral: 27%). Conclusion: The "one and a half" approach increases the ability to control and completely resect the lesion beyond the medial edge of the internal carotid artery on the same side of the nostril involving endoscope. It is a good supplement and improvement to the bilateral approach.

Abstract
Objective: To explore the indications and safety of orthopedic liver transplantation for polycystic liver disease (PLD). Methods: Data of 11 patients with PLD who underwent orthotopic liver transplantation between 2004 and 2013 was retrospectively analyzed. Demographic, clinical and follow-up data were collected for statistical analysis. The survival rate was calculated by Kaplan-Meier method. Results: Over a period of 10 years, the patients received modified piggyback orthopedic liver transplantation (n=9) or combined liver-kidney transplantation (n=2) for PLD. The recipients' median age was 56 years. Seven patients were classified as Gigot type Ⅱ PLD, and four were classified as Gigot type Ⅲ PLD. Eight patients had severe decreased mobility (Eastern Cooperative Oncology Group, ECOG≥3). Only three cases were Child-Pguh Class C patients and the model for end-stage liver disease (MELD) score was>20. The mean hospitalization duration was (45.4±15.3) days, and the mean length of stay in intensive care unit was (4.1±1.9) days. The perioperative mortality was 18.2% and morbidity of complications was 63.6%. The median follow-up period was 111 months. Two patients died of severe complications after combined liver-kidney transplantation. One patient died of ischemia cholangitis during follow-up. The actuarial 1-, 5-and 10-year survival rate during the follow-up period was 82.2%, 81.8%, and 65.5%, respectively. Conclusions: Liver transplantation is the only curative and safe procedure for PLD, and it provides a good long-term prognosis and high quality of life for PLD patients. Liver transplantation could be a primary option in treating progressive or advanced PLD.

Here, we report the discovery of the youngest well-preserved fossil palm leaves from Tibet. They were recovered from the Late Paleogene (Chattian), ca. 25.5 ± 0.5 million years, paleolake sediments within the Lunpola Basin (32.033°N, 89.767°E), central QTP at a present elevation of 4655 m. The anatomy of palms renders them intrinsically susceptible to freezing, imposing upper bounds on their latitudinal and altitudinal distribution. Combined with model-determined paleoterrestrial lapse rates, this shows that a high plateau cannot have existed in the core of Tibet in the Paleogene. Instead, a deep paleovalley, whose floor was <2.3 km above mean sea level bounded by (>4 km) high mountain systems, formed a topographically highly varied landscape. This finding challenges prevailing views on tectonic processes, monsoon dynamics, and the evolution of Asian biodiversity.

Abstract
Hepatitis E virus (HEV) infection usually causes acute hepatitis and has a self-limiting progression. The patients often recover within 6 months with good prognosis. Recent studies have found that HEV infection may become chronic in special situations, which manifests as persistent liver function abnormalities for at least 6 months after acute HEV infection and the presence of viral nucleic acid in serum, feces, and/or liver tissue. Chronicity of HEV infection mainly occurs in immunocompromised patients, and it is rare but very dangerous in clinical practice. An understanding of the pathogenesis, clinical manifestations, treatment methods, and preventive measures of chronicity of HEV infection helps clinical physicians develop an effective management regimen and improve patient prognosis. This article introduces related issues, in order to raise the awareness of this disease among clinical physicians.
