Abstract
The Swiss Light Source facilitates fragment-based drug-discovery campaigns for academic and industrial users through the Fast Fragment and Compound Screening (FFCS) software suite. This framework is further enriched by the option to utilize the Smart Digital User (SDU) software for automated data collection across the PXI, PXII and PXIII beamlines. In this work, the newly developed HEIDI webpage (https://heidi.psi.ch) is introduced: a platform crafted using state-of-the-art software architecture and web technologies for sample management of rotational data experiments. The HEIDI webpage features a data-review tab for enhanced result visualization and provides programmatic access through a representational state transfer application programming interface (REST API). The migration of the local FFCS MongoDB instance to the cloud is highlighted and detailed. This transition ensures secure, encrypted and consistently accessible data through a robust and reliable REST API tailored for the FFCS software suite. Collectively, these advancements not only significantly elevate the user experience, but also pave the way for future expansions and improvements in the capabilities of the system.

Abstract
Objective: To understand the situation and epidemic characteristics of injury deaths among children aged 5 to 24 years in Jiangsu Province from 2012 to 2021 and the trend of annual changes. Methods: The main injury mortality data of children and adolescents was collected, and the crude and standardized mortality rates of road traffic accidents, drowning, suicide, and accidental falls among children and adolescents over a decade and the annual average percentage of change (AAPC) were calculated. The main injury mortality characteristics and trends of children and adolescents of different age groups and genders were analyzed. Results: The total number of injury deaths among 5 to 24 adolescents in Jiangsu Province was 16 052, with a standardized mortality rate of 9.58/100 000. There was no significant trend in the overall standardized mortality rate of injuries (AAPC=-3.450%, P=0.055). The standardized mortality rate of road traffic injuries among children and adolescents showed a decreasing trend over the past decade, with statistical significance (AAPC=-9.406%, P<0.001). The standardized suicide mortality rate showed an upward trend over the past decade, with statistical significance (AAPC=9.000%, P=0.001). The overall injury mortality rate showed an upward trend with age. Suicide rates in males and females were on the rise and both have statistical significance (AAPC=9.420% and AAPC=9.607%, both P<0.05). The standardized mortality rates of female traffic accidents, drowning, and male traffic accidents showed a decreasing trend and were statistically significant (AAPC for female traffic accidents=-7.364%, AAPC for female drowning=-5.352%, and AAPC for male traffic accidents=-10.242%, all P<0.05). The standardized mortality rate of urban and rural traffic accidents showed a decreasing trend and was statistically significant(AAPC=-7.899% and AAPC=-9.421%, both P<0.001). The standardized suicide mortality rate showed an upward trend and statistical significance (AAPC=11.009% and AAPC=7.528%, both P<0.05). Conclusions: The overall injury situation of children and adolescents in Jiangsu Province improved in the past decade from 2012 to 2021, but the suicide mortality rate was on the rise. It is necessary to focus on the mental health issues of this age group and to strengthen the prevention and control of suicide among children and adolescents, in Jiangsu.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) and surgical resection are the standard of care for cT1N0M0 esophageal cancer (EC), whereas definitive chemoradiotherapy (d-CRT) is a treatment option. Nevertheless, the comparative efficiency and safety of ESD, surgery and d-CRT for cT1N0M0 EC remain unclear. AIM To compare the efficiency and safety of ESD, surgery and d-CRT for cT1N0M0 EC. METHODS We retrospectively analyzed the hospitalized data of a total of 472 consecutive patients with cT1N0M0 EC treated at Sun Yat-sen University Cancer center between 2017-2019 and followed up until October 30th, 2022. We analyzed demographic, medical recorded, histopathologic characteristics, imaging and endoscopic, and follow-up data. The Kaplan-Meier method and Cox proportional hazards modeling were used to analyze the difference of survival outcome by treatments. Inverse probability of treatment weighting (IPTW) was used to minimize potential confounding factors. RESULTS We retrospectively analyzed patients who underwent ESD (n = 99) or surgery (n = 220) or d-CRT (n = 16) at the Sun Yat-sen University Cancer Center from 2017 to 2019. The median follow-up time for the ESD group, the surgery group, and the d-CRT group was 42.0 mo (95%CI: 35.0-60.2), 45.0 mo (95%CI: 34.0-61.75) and 32.5 mo (95%CI: 28.3-40.0), respectively. After adjusting for background factors using IPTW, the highest 3-year overall survival (OS) rate and 3-year recurrence-free survival (RFS) rate were observed in the ESD group (3-year OS: 99.7% and 94.7% and 79.1%; and 3-year RFS: 98.3%, 87.4% and 79.1%, in the ESD, surgical, and d-CRT groups, respectively). There was no difference of severe complications occurring between the three groups (P ≥ 0.05). Multivariate analysis showed that treatment method, histology and depth of infiltration were independently associated with OS and RFS. CONCLUSION For cT1N0M0 EC, ESD had better long-term survival and lower hospitalization costs than those who underwent d-CRT and surgery, with a similar rate of severe complications occurring.

Abstract
BACKGROUND Many neuroscience and neurology studies have forced a reconsideration of the traditional motor-related scope of cerebellar function, which has now expanded to include various cognitive functions. Spinocerebellar ataxia type 3 (SCA3; the most common hereditary ataxia) is neuropathologically characterized by cerebellar atrophy and frequently presents with cognitive impairment. OBJECTIVE To characterize cognitive impairment in SCA3 and investigate the cerebellum-cognition associations. METHODS This prospective, cross-sectional cohort study recruited 126 SCA3 patients and 41 healthy control individuals (HCs). Participants underwent a brain 3D T1-weighted images as well as neuropsychological tests. Voxel-based morphometry (VBM) and region of interest (ROI) approaches were performed on the 3D T1-weighted images. CERES was used to automatically segment cerebellums. Patients were grouped into cognitively impaired (CI) and cognitively preserved (CP), and clinical and MRI parameters were compared. Multivariable regression models were fitted to examine associations between cerebellar microstructural alterations and cognitive domain impairments. RESULTS Compared to HCs, SCA3 patients showed cognitive domain impairments in information processing speed, verbal memory, executive function, and visuospatial perception. Between CI and CP subgroups, the CI subgroup was older and had lower education, as well as higher severity scores. VBM and ROI analyses revealed volume loss in cerebellar bilateral lobule VI, right lobule Crus I, and right lobule IV of the CI subgroup, and all these cerebellar lobules were associated with the above cognitive domain impairments. CONCLUSIONS Our findings demonstrate the multiple cognitive domain impairments in SCA3 patients and indicate the responsible cerebellar lobules for the impaired cognitive domain(s).

Abstract
Perioperative chemotherapy is the standard treatment for locally advanced gastric or gastro-esophageal junction cancer, and the addition of programmed cell death 1 (PD-1) inhibitor is under investigation. In this randomized, open-label, phase 2 study (NEOSUMMIT-01), patients with resectable gastric or gastro-esophageal junction cancer clinically staged as cT3-4aN + M0 were randomized (1:1) to receive either three preoperative and five postoperative 3-week cycles of SOX/XELOX (chemotherapy group, n = 54) or PD-1 inhibitor toripalimab plus SOX/XELOX, followed by toripalimab monotherapy for up to 6 months (toripalimab plus chemotherapy group, n = 54). The primary endpoint was pathological complete response or near-complete response rate (tumor regression grade (TRG) 0/1). The results showed that patients in the toripalimab plus chemotherapy group achieved a higher proportion of TRG 0/1 than those in the chemotherapy group (44.4% (24 of 54, 95% confidence interval (CI): 30.9%-58.6%) versus 20.4% (11 of 54, 95% CI: 10.6%-33.5%)), and the risk difference of TRG 0/1 between toripalimab plus chemotherapy group and chemotherapy group was 22.7% (95% CI: 5.8%-39.6%; P = 0.009), meeting a prespecified endpoint. In addition, a higher pathological complete response rate (ypT0N0) was observed in the toripalimab plus chemotherapy group (22.2% (12 of 54, 95% CI: 12.0%-35.6%) versus 7.4% (4 of 54, 95% CI: 2.1%-17.9%); P = 0.030), and surgical morbidity (11.8% in the toripalimab plus chemotherapy group versus 13.5% in the chemotherapy group) and mortality (1.9% versus 0%), and treatment-related grade 3-4 adverse events (35.2% versus 29.6%) were comparable between the treatment groups. In conclusion, the addition of toripalimab to chemotherapy significantly increased the proportion of patients achieving TRG 0/1 compared to chemotherapy alone and showed a manageable safety profile.

Abstract
Titanium-rich metastable medium-entropy alloys, designed for low elastic moduli, sacrifice strength. However, enhancing their mechanical strength is crucial for bio-implant applications. This study aims to enhance the mechanical properties and corrosion resistance of a metastable Ti80-Nb10-Mo5-Sn5 medium-entropy alloy using various treatments, including cold rolling (at 50% and 75% reduction) and precipitation hardening (at room temperature, 150 °C, 350 °C, 550 °C, and 750 °C). The results showed that the alloy underwent a stress-induced martensitic transformation during the rolling process. Notably, the α phase was precipitated in the β grain boundaries after 30 days of precipitation hardening at room temperature. The yield strengths of the alloy increased by 51% and 281.9% after room-temperature precipitation and 75% cold rolling, respectively. In potentiodynamic corrosion tests conducted in phosphate-buffered saline solution, the pitting potentials of the alloy treated using various conditions were higher than 1.8 V, and no pitting holes were observed on the surface of the alloys. The surface oxide layer of the alloy was primarily composed of TiO2, Nb2O5, MoO3, and SnO2, contributing to the alloy's exceptional corrosion and pitting resistance. The 75% rolled Ti80-Nb10-Mo5-Sn5 demonstrates exceptional mechanical properties and high corrosion resistance, positioning it as a promising bio-implant candidate.

Abstract
Epstein‒Barr virus (EBV)-associated gastric cancer (GC) manifests an intriguing immunotherapy response. However, the cellular basis for EBV-imprinted tumour immunity and on-treatment response remains undefined. This study aimed to finely characterize the dynamic tumour immune contexture of human EBV (+) GC treated with immunochemotherapy by longitudinal scRNA-seq and paired scTCR/BCR-seq. EBV (+) GC exhibits an inflamed-immune phenotype with increased T-cell and B-cell infiltration. Immunochemotherapy triggers clonal revival and reinvigoration of effector T cells which step to determine treatment response. Typically, an antigen-specific ISG-15+CD8+ T-cell population is highly enriched in EBV (+) GC patients, which represents a transitory exhaustion state. Importantly, baseline intratumoural ISG-15+CD8+ T cells predict immunotherapy responsiveness among GC patients. Re-emerged clonotypes of pre-existing ISG-15+CD8+ T cells could be found after treatment, which gives rise to a CXCL13-expressing effector population in responsive EBV (+) tumours. However, LAG-3 retention may render the ISG-15+CD8+ T cells into a terminal exhaustion state in non-responsive EBV (+) tumours. In accordance, anti-LAG-3 therapy could effectively reduce tumour burden in refractory EBV (+) GC patients. Our results delineate a distinct implication of EBV-imprinted on-treatment T-cell immunity in GC, which could be leveraged to optimize the rational design of precision immunotherapy.

Abstract
AIMS The aim of this study was to develop, implement and evaluate a nurse-led shared decision-making model of care for discussing the use of complementary and alternative medicine with diabetic patients and to explore to what extent the risk-benefit assessment of using complementary and alternative medicine can provide a framework for facilitating nurse-patient dialogue and strengthening patient involvement in their disease management. DESIGN Participatory action research with pre-post intervention. METHODS A two-run cycle of action and spirals from participatory action research was undertaken using a purposive sampling method to involve healthcare professionals and diabetic patients from September 2021 to June 2022. The nurse-led shared decision-making model of care was designed and implemented congruent with participatory action research principles. Quantitative measures were collected about patients' perceived involvement in shared decision-making and their understanding of the risks and benefits of using complementary and alternative medicine. Patients' outcomes of disease control (fasting plasma glucose and HbA1c) were also collected. Data were analysed using IBM SPSS software (version 28). Interviews were summarized using thematic analysis. An EQUATOR Network guideline for participatory action research supported the preparation of this paper. RESULTS Comparison of pre-post intervention outcomes showed that patients' scale scores on shared decision-making involvement and understanding of the risk-benefit of using complementary and alternative medicine improved significantly after implementing the model. Fasting plasma glucose improved only slightly after a 3-month follow-up. CONCLUSIONS The care model strengthens patient involvement in their disease management and makes appropriate decisions about CAM use that should reduce potentially harmful side effects or interactions between CAM and conventional medicine. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE The shared decision-making model of care incorporates evidence-based CAM research into practice, facilitates the standardization of CAM management in diabetes, improves care options for patients and educates nurses about CAM use in managing diabetes.

Abstract
Objective: To investigate the familial heritability of endometriosis and to compare the clinical characteristics of patients with or without a family history of endometriosis. Methods: From January 2020 to June 2022, 850 patients with endometriosis confirmed by laparotomy or laparoscopy in Peking University Third Hospital were included in this study. Clinical data were collected, family history was followed up, and the differences of clinical indicators between patients with and without family history of endometriosis were compared. Results: A total of 850 patients were enrolled, with an average age of (33.8±7.0) years old, 315 (37.1%, 315/850) patients in stage Ⅲ and 496 (58.4%, 496/850) patients in stage Ⅳ. There were 100 patients with family history of endometriosis, accounting for 11.8% (100/850). Most of the 113 relatives involved were mothers, daughters and sisters (76.1%, 86/113), 81.5% (22/27) of the second and third degree relatives were maternal relatives. The median ages of patients with and without family history of endometriosis were 30 and 33 years old respectively at the time of diagnosis. The unmarried rate of patients with family history was higher [42.0% (42/100) vs 26.3% (197/750)]. The percentage of dysmenorrhea patients with family history was higher [89.0% (89/100) vs 55.5% (416/750)]. The medians of dysmenorrhea score in patients with and without family history were 6 and 2, and the median durations of dysmenorrhea were 10 and 1 years. There were significant differences in age, marital status, percentage of dysmenorrhea, dysmenorrhea score and duration (all P<0.001). The median levels of serum cancer antigen (CA) 125 in patients with family history and patients without family history at the time of diagnosis were 57.5 and 46.9 kU/L respectively, with a statistically significant difference (P<0.05). However, there were no significant differences between the two groups in nationality, bady mass index, menarche age, menstrual cycle, menstrual period, menstrual volume, serum CA19-9 level, cyst location and size, stage, history of adverse pregnancy and childbirth, infertility, adenomyosis and deep infiltrating endometriosis (all P>0.05). By comparing the specific conditions of dysmenorrhea patients with and without family history of endometriosis, there were no significant differences between the two groups in terms of the age of onset of dysmenorrhea, duration of dysmenorrhea, primary and secondary dysmenorrhea, and progressive aggravation of dysmenorrhea (all P>0.05). The difference in the degree of dysmenorrhea in dysmenorrhea patients with family history of endometriosis was significant (P<0.001). Conclusions: The incidence of endometriosis has a familial tendency, and most of the involved relatives are the first degree relatives. Compared with patients without family history of endometriosis, endometriosis patients with family history are diagnosed at an earlier age, with higher percentage of dysmenorrhea, had more severe dysmenorrhea and higher serum CA125 level.

Abstract
Objective The objective of this study was to screen lymphoma radiotherapy-resistant genes using CRISPR activation (CRISPRa). Methods The Human CRISPRa library virus was packaged and then transfected into lymphoma cells to construct an activation library cell line, which was irradiated at the minimum lethal radiation dose to screen radiotherapy-resistant cells. Radiotherapy-resistant cell single-guide RNA (sgRNA) was first amplified by quantitative polymerase chain reaction (qPCR) in the coding region and then subject to next-generation sequencing (NGS) and bioinformatics analysis to screen radiotherapy-resistant genes. Certain radiotherapy-resistant genes were then selected to construct activated cell lines transfected with a single gene so as to further verify the relationship between gene expression and radiotherapy resistance. Results A total of 16 radiotherapy-resistant genes, namely, C20orf203, MTFR1, TAF1L, MYADM, NIPSNAP1, ZUP1, RASL11A, PSMB2, PSMA6, OR8H3, TMSB4Y, CD300LF, EEF1A1, ATP6AP1L, TRAF3IP2, and SNRNP35, were screened based on the NGS results and bioinformatics analysis of the radiotherapy-resistant cells. Activated cell lines transfected with a single gene were constructed using 10 radiotherapy-resistant genes. The qPCR findings showed that, when compared with the control group, the experimental group had significantly up-regulated mRNA expression of MTFR1, NIPSNAP1, ZUP1, PSMB2, PSMA6, EEF1A1, TMSB4Y and TAF1L (p < 0.05). No significant difference in the mRNA expression of AKT3 or TRAF3IP2 (p > 0.05) was found between the two groups (p > 0.05). Conclusion The 16 genes screened are potential lymphoma radiotherapy-resistant genes. It was initially determined that the high expression of 8 genes was associated with lymphoma radiotherapy resistance, and these genes could serve as the potential biomarkers for predicting lymphoma radiotherapy resistance or as new targets for therapy.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) and magnifying endoscopy (ME) reliably determine indications for endoscopic resection in patients with superficial esophageal squamous cell carcinoma (SESCC). ME is widely accepted for predicting the invasion depth of superficial esophageal cancer with satisfying accuracy. However, the addition of EUS is controversial.
AIM To evaluate the diagnostic efficiency of ME vs EUS for invasion depth prediction and investigate the influencing factors in patients with SESCC to determine the best diagnostic model in China.
METHODS We retrospectively analyzed patients with suspected SESCC who completed both ME and EUS and then underwent endoscopic or surgical resection at Sun Yat-Sen University Cancer Center between January 2018 and December 2021. We evaluated and compared the diagnostic efficiency of EUS and ME according to histological results, and investigated the influencing factors.
RESULTS We included 152 lesions from 144 patients in this study. The diagnostic accuracies of ME and EUS in differentiating invasion depth were not significantly different (73.0% and 66.4%, P = 0.24); both demonstrated moderate consistency with the pathological results (ME: kappa = 0.58, 95% confidence interval [CI]: 0.48-0.68, P < 0.01; EUS: kappa = 0.46, 95%CI: 0.34-0.57, P < 0.01). ME was significantly more accurate in the diagnosis of high-grade intraepithelial (HGIN) or carcinoma in situ (odds ratio [OR] = 3.62, 95%CI: 1.43-9.16, P = 0.007) subgroups. Using a miniature probe rather than conventional EUS can improve the accuracy of lesion depth determination (82.3% vs 49.3%, P < 0.01). Less than a quarter of circumferential occupation and application of a miniature probe were independent risk factors for the accuracy of tumor invasion depth as assessed by EUS (< 1/4 circumferential occupation: OR = 3.07, 95%CI: 1.04-9.10; application of a miniature probe: OR = 5.28, 95%CI: 2.41-11.59, P < 0.01). Of the 41 lesions (41/152, 27.0%) that were misdiagnosed by ME, 24 were corrected by EUS (24/41, 58.5%).
CONCLUSION Preoperative diagnosis of SESCC should be conducted endoscopically using white light and magnification. In China, EUS can be added after obtaining patient consent. Use of a high-frequency miniature probe or miniature probe combined with conventional EUS is preferable.

Abstract
Continuous wave dual-wavelength lasers at 1342 and 1525 nm are developed by using separate Nd:YVO4 and YVO4 crystals to form compactly coupled cavities for fundamental and Raman waves, respectively. The design of the coupled cavity not only reduces the thermal lensing effect in the Nd:YVO4 crystal, but also improves the stimulated Raman scattering (SRS) efficiency in the undoped YVO4 crystal. In addition, the Raman crystal is coated to form a highly reflective mirror to minimize cavity losses. By using a plano-concave cavity with a pump power of 40 W, the output powers of the fundamental and Raman waves are 470 mW and 310 mW, respectively. Changed to a concave cavity, the output powers of fundamental and Raman waves are 220 mW and 510 mW, respectively. Basis on the dual-wavelength operation, the maximum output power at 714 nm can reach 2.0 W via the sum frequency generation. A light source at 714 nm can be used for laser spectroscopy of atomic and ionic radium isotopes.

Abstract
Objective: To investigate the clinical value of the bipolar tweezers-clamp for the hepatic parenchymal transection in the resection of hepatocellular carcinoma. Methods: From January 2020 to January 2021,63 patients with the hepatocellular carcinoma for hepatectomy at Department of Hepatopancreatobiliary Surgery,Yuebei People's Hospital Affiliated to Shantou University Medical College were analyzed retrospectively.According to the different instruments used in the hepatic parenchymal transection,the patients were divided into bipolar tweezers-clamp group and ultrasonic scalpel group.There were 32 patients in bipolar tweezers-clamp group,with age of (55.5±10.5)years(range:37 to 78 years),including 22 males and 10 females,tumor size was (6.0±3.4)cm(range:2.4 to 13.4 cm). There were 6 patients with portal vein tumor thrombus and 5 patients with portal hypertension. There were 31 patients in ultrasonic scalpel group,with aged(57.8±10.1)years(range:37 to 79 years),including 27males and 4 females,tumor size was(7.9±5.1)cm(range: 2.4 to 21.3 cm),3 patients with portal vein tumor thrombus and 2 patients with portal hypertension. The preoperative baseline data,operation time,blood loss,postoperative liver function and the complications were compared between two groups using t test,χ2 test and Fisher exact probabilityrespectively. Results: The operation was successfully completed in both groups.Compared with the ultrasonic scalpel group,the operation time was significantly shorter((219.3±76.4)minutes vs.(294.0±100.8)minutes,t=-3.322,P=0.002),the blood loss was less((250(475)ml vs. 500(1 050)ml,t=-2.307,P=0.026),the concentrate red blood cells transfusion volume was less(0.92(0.88)U vs. 2.32(4.00)U,Z=-1.987,P=0.047) in the bipolar tweezers-clamp group.The postoperative serum ALB level was higher in the bipolar tweezers-clamp group than that in the ultrasonic scalpel group((33.5±6.1)g/L vs. (29.5±4.2)g/L,t=3.226,P=0.020) on postoperative day 1;((35.7±4.5)g/L vs.(30.1±3.2)g/L,t=5.575,P<0.01) on postoperative day 3;((33.2±3.7)g/L vs. (31.0±4.4)g/L,t=3.020,P=0.004) on postoperative day 7. There was no significant difference in serum ALT,TBIL and PT level between the two groups(all P>0.05).No postoperative bile leakage occurred in both groups.The postoperative complications occurred in 8 cases(25.0%)in the bipolar tweezers-clamp group,including liver failure in one,and in 11 cases(35.5%)in the ultrasonic scalpel group,including liver failure in two(P>0.05). Conclusion: The bipolar tweezers-clamp is a safe and reliable method for the hepatic parenchymal transaction,which is quick and less bleeding during the hepatic resection.

Abstract
Objective: To analyze the clinical characteristics and prognostic value of liver function in a large samples of patients with anti-glycoprotein 210 (gp210 antibody) positive primary biliary cholangitis (PBC). Methods: A retrospective study was performed on 931 PBC cases in Beijing You'an Hospital affiliated to Capital Medical University from 2010 to 2019. According to the detection of gp210 antibody, 318 cases were divided into gp210 antibody positive group (positive group) and 613 cases were divided into gp210 antibody negative group (negative group). The differences in demographic, medical history, clinical indicators, B-ultrasound and pathological indicators as well as the histopathological basis were compared between the two groups. SPSS 16.0 software was used for statistical analysis. Measurement data were analyzed by t-test or rank sum test, and enumeration data by χ2 test. Multivariate analysis was used for logistic test, and and survival analysis was used for prognosis. Results: The positive and the negative groups were compared. The ratio of male to female was significantly higher in positive than negative group (1:5.35 vs. 1:9.73, P<0.05), and the difference was statistically significant. The proportion of hormone use in history of past diagnosed and treated was higher in positive than negative group (12.9% vs. 3.47%, P<0.05), and the difference was statistically significant. The detection of biochemical indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT) were higher in positive than the negative group (51.1 U/L vs. 41.1 U/L, 62.6 U/L vs. 49.6 U/L, 24.1 μmol/L vs. 17.9 μmol/L, 228.3 U/L vs. 169.6 U/L, 203.9 U/L vs. 147.6 U/L), (P<0.05), and the differences were statistically significant. Antinuclear antibody (ANA)-positive rate, high titer ratio and immunoglobulin G (IgG) levels were higher in positive than negative group (95.2% vs. 81.6%, 69.7% vs. 48.8%, 17.2 g/L vs. 16.2 g/L), (P<0.05), and the differences were statistically significant. The incidence of liver failure was higher in positive than negative group (P<0.05). CK7 and inflammation score were higher in positive group than negative group in liver histopathological observations (0.83±0.53 vs. 0.28±0.47; 1.06±0.39 vs. 0.54±0.65), (P<0.05), and the differences were statistically significant. Conclusion: The illness condition of patients with gp210 antibody positive PBC is more severe than patients with gp210 antibody negative PBC, and the incidence of liver failure is significantly increased. Cholangiocytes may be the histopathological basis of the clinical characteristics of gp210 antibody positive PBC patients.

Abstract
Objective: To analyze the characteristics of clinical and laboratory indexes in patients with liver disease with positive anti-liver cytosol antibody type 1 (anti-LC1), in order to provide references for clinical and differential diagnosis. Methods: The clinical data of 23 832 inpatients and outpatients with positive anti-LC1 autoantibodies detected in routine autoantibody test from January 2010 to January 2020 were retrospectively analyzed, and their clinical and laboratory indexes were compared. Western blotting was used to detect anti-LC1, anti-soluble liver antigen antibody (anti-SLA), anti-glycoprotein 210 antibodies and anti-nucleosome 100 antibodies. Indirect immunofluorescence assay was used to detect anti-nuclear antibody (ANA), anti-mitochondrial antibody, anti-Smooth muscle antibody (ASMA), anti-liver and kidney microsomal antibody (anti-LKM) and other autoantibodies. Normally distributed measurement data between the two groups were compared by independent-sample t-test, and the multiple groups comparison were compared by one-way analysis of variance. Non-normally distributed measurement data were compared by non-parametric rank sum test. Results: 38 anti-LC1 positive patients were detected in 23832 autoantibody tests. The age of initial diagnosis ranged from 11.0 to 84.0 (50.6 ± 16.0) years. There were 8 males (21.1%) and 30 females (78.9%). A total of 31 cases (81.6%) were positive for anti-LC1 and ANA, and the dominant karyotype was speckled pattern, accounting for 54.8%. Five cases (13.2%) were positive for ASMA, and no simultaneous positive with anti-LKM or anti-SLA. Among the 38 anti-LC1 positive patients, 9 were diagnosed with autoimmune hepatitis (AIH), 6 with possible AIH, 6 with primary biliary cholangitis (PBC), 8 with hepatitis B, 2 with hepatitis C, 1 with alcoholic liver disease, 2 with non-alcoholic fatty liver disease, 1 with drug-induced liver injury, 1 with hepatolenticular degeneration, and 2 with tumor. Confirmed and probable AIH cases accounted for 39.5% (15/38) of anti-LC1 positive cases. Among anti-LC1 positive patients, 47.4% (18/38) had entered the stage of liver cirrhosis. AIH group globulin level was higher than HBV group (P = 0.006) and other disease groups (P = 0.001). AIH group IgG level was higher than PBC group (P = 0.027), HBV group (P = 0.009) and other disease groups (P = 0.004). the of the PBC group IgM level was higher than AIH group (P = 0.003), HBV group (P = 0.003) and other disease groups (P = 0.006). Conclusion: Anti-LC1 is not only detected in AIH, but also observed in patients with primary biliary cholangitis, hepatitis B and C, alcoholic and non-alcoholic liver disease, drug-induced liver injury, hereditary metabolic liver disease and tumor. In addition, it is mainly female gender dominance and nearly half of ANA-positive young, middle-aged and elderly patients develop liver cirrhosis. For the diagnosis of type 2 autoimmune hepatitis, whether anti-LC1 is a specific antibody needs further research, but if AIH is highly suspected, this antibody can be used as a substitute.

Abstract
Synchrony Respiratory Tracking system adapted from CyberKnife has been introduced in Radixact to compensate the tumor motion caused by respiration. This study aims to compare the modeling accuracy of the Synchrony system between Radixact and CyberKnife. Two Synchrony plans based on fiducial phantoms were created for CyberKnife and Radixact, respectively. Different respiratory motion traces were used to drive a motion platform to move along the superoinferior and left-right direction. The cycle time and the amplitude of target/surrogate motion of one selected motion trace were scaled to investigate the dependence of modeling accuracy on the motion characteristic. The predicted target position, the correlation error, potential difference (Radixact only) and standard error (CyberKnife only) were extracted from raw data or log files of the two systems. The modeling accuracy was evaluated by calculating the root-mean-square (RMS) error between the predicted target positions and the input motion trace. A threshold T95 within which 95% of the potential difference or the standard error lay was defined and evaluated. Except for the motion trace with a small amplitude and a good (linear) correlation between target and surrogate motion, Radixact showed smaller RMS errors than CyberKnife. The RMS error of both systems increased with the motion amplitude and showed a decreasing trend with the increasing cycle time. No correlation was found between the RMS error and the amplitude of surrogate motion. T95 could be a good estimator of modeling accuracy for CyberKnife rather than Radixact. The correlation error defined in Radixact were largely affected by the number of fiducial markers and the setup error. In general, the modeling accuracy of the Radixact Synchrony system is better than that of the CyberKnife Synchrony system under unfavorable conditions.

Abstract
Aim: Cell invasion leading to metastasis is a major cause of treatment failure in head-neck cancers (HNCs). Identifying prognostic molecules associated with invasiveness is imperative for clinical applications. Materials & methods: A systemic approach was used to globally survey invasion-related genes, including transcriptomic profiling, pathway analysis, data mining and prognostic assessment using TCGA-HNSC dataset. Results: Six functional pathways and six hub molecules (LAMA3, LAMC2, THBS1, IGF1R, PDGFB and TGFβ1) were identified that significantly contributed to cell invasion, leading to poor survival in HNC patients. Combinations of multiple biomarkers substantially increased the probability of accurately predicting prognosis. Conclusion: Our six defined invasion-related molecules may be used as a panel signature in precision medicine for prognostic indicators or molecular therapeutic targets for HNC.

Abstract
Escherichia coli Nissle (EcN), a probiotic bacterium protects against several disorders. Multiple reports have studied the pathways involved in cardiac hypertrophy. However, the effects of probiotic EcN against diabetes-induced cardiac hypertrophy remain to be understood. We administered five weeks old Wistar male (271±19.4 g body weight) streptozotocin-induced diabetic rats with 109 cfu of EcN via oral gavage every day for 24 days followed by subjecting the rats to echocardiography to analyse the cardiac parameters. Overexpressed interleukin (IL)-6 induced the MEK5/ERK5, JAK2/STAT3, and MAPK signalling cascades in streptozotocin-induced diabetic rats. Further, the upregulation of calcineurin, NFATc3, and p-GATA4 led to the elevation of hypertrophy markers, such as atrial and B-type natriuretic peptides. In contrast, diabetic rats supplemented with probiotic EcN exhibited significant downregulated IL-6. Moreover, the MEK5/ERK5 and JAK2/STAT3 cascades involved during eccentric hypertrophy and MAPK signalling, including phosphorylated MEK, ERK, JNK, and p-38, were significantly attenuated in diabetic rats after supplementation of EcN. Western blotting and immunofluorescence revealed the significant downregulation of NFATc3 and downstream mediators, thereby resulting in the impairment of cardiac hypertrophy. Taken together, the findings demonstrate that supplementing probiotic EcN has the potential to show cardioprotective effects by inhibiting diabetes-induced cardiomyopathies.

Abstract
Purpose. This study aims to evaluate the performance of a commercial 1.5 T MR-Linac by analyzing its patient-specific quality assurance (QA) data collected during one full year of clinical operation.Methods and Materials. The patient-specific QA system consisted of offline delivery QA (DQA) and online calculation-based QA. Offline DQA was based on ArcCHECK-MR combined with an ionization chamber. Online QA was performed using RadCalc that calculated and compared the point dose calculation with the treatment planning system (TPS). A total of 24 patients with 189 treatment fractions were enrolled in this study. Gamma analysis was performed and the threshold that encompassed 95% of QA results (T95) was reported. The plan complexity metric was calculated for each plan and compared with the dose measurements to determine whether any correlation existed.Results. All point dose measurements were within 5% deviation. The mean gamma passing rates of the group data were found to be 96.8 ± 4.0% and 99.6 ± 0.7% with criteria of 2%/2mm and 3%/3mm, respectively. T95 of 87.4% and 98.2% was reported for the overall group with the two passing criteria, respectively. No statistically significant difference was found between adaptive treatments with adapt-to-position (ATP) and adapt-to-shape (ATS), whilst the category of pelvis data showed a better passing rate than other sites. Online QA gave a mean deviation of 0.2 ± 2.2%. The plan complexity metric was positively correlated with the mean dose difference whilst the complexity of the ATS cohort had larger variations than the ATP cohort.Conclusions. A patient-specific QA system based on ArcCHECK-MR, solid phantom and ionization chamber has been well established and implemented for validation of treatment delivery of a 1.5 T MR-Linac. Our QA data obtained over one year confirms that good agreement between TPS calculation and treatment delivery was achieved.

Abstract
In recent decades, the global incidence of dengue has increased. Affected countries have responded with more effective surveillance strategies to detect outbreaks early, monitor the trends, and implement prevention and control measures. We have applied newly developed machine learning approaches to identify laboratory-confirmed dengue cases from 4,894 emergency department patients with dengue-like illness (DLI) who received laboratory tests. Among them, 60.11% (2942 cases) were confirmed to have dengue. Using just four input variables [age, body temperature, white blood cells counts (WBCs) and platelets], not only the state-of-the-art deep neural network (DNN) prediction models but also the conventional decision tree (DT) and logistic regression (LR) models delivered performances with receiver operating characteristic (ROC) curves areas under curves (AUCs) of the ranging from 83.75% to 85.87% [for DT, DNN and LR: 84.60% ± 0.03%, 85.87% ± 0.54%, 83.75% ± 0.17%, respectively]. Subgroup analyses found all the models were very sensitive particularly in the pre-epidemic period. Pre-peak sensitivities (<35 weeks) were 92.6%, 92.9%, and 93.1% in DT, DNN, and LR respectively. Adjusted odds ratios examined with LR for low WBCs [≤ 3.2 (x103/μL)], fever (≥38°C), low platelet counts [< 100 (x103/μL)], and elderly (≥ 65 years) were 5.17 [95% confidence interval (CI): 3.96-6.76], 3.17 [95%CI: 2.74-3.66], 3.10 [95%CI: 2.44-3.94], and 1.77 [95%CI: 1.50-2.10], respectively. Our prediction models can readily be used in resource-poor countries where viral/serologic tests are inconvenient and can also be applied for real-time syndromic surveillance to monitor trends of dengue cases and even be integrated with mosquito/environment surveillance for early warning and immediate prevention/control measures. In other words, a local community hospital/clinic with an instrument of complete blood counts (including platelets) can provide a sentinel screening during outbreaks. In conclusion, the machine learning approach can facilitate medical and public health efforts to minimize the health threat of dengue epidemics. However, laboratory confirmation remains the primary goal of surveillance and outbreak investigation.

Abstract
Alzheimer's disease (AD) is characterized by memory dysfunction, Aβ plaques together with phosphorylated tau-associated neurofibrillary tangles. Unfortunately, the present existing drugs for AD only offer mild symptomatic cure and have more side effects. As such, developments of effective, nontoxic drugs are immediately required for AD therapy. Present study demonstrates a novel role of Chinese medicine prescription Yuan-Hu Zhi Tong (YZT) in treating AD, and it has substantiated the in vivo effectiveness of YZT in two different transgenic mice models of AD, namely P301S tau and 3XTg-AD mice. Oral treatment of YZT significantly ameliorates motor dysfunction as well as promotes the clearance of aggregated tau in P301S tau mice. YZT improves the cognitive function and reduces the insoluble tau aggregates in 3XTg-AD mice model. Furthermore, YZT decreases the insoluble AT8 positive neuron load in both P301S tau and 3XTg-AD mice. Using microarray and the "Connectivity Map" analysis, we determined the YZT-induced changes in expression of signaling molecules and revealed the potential mechanism of action of YZT. YZT might regulate ubiquitin proteasomal system for the degradation of tau aggregates. The research results show that YZT is a potential drug candidate for the therapy of tau pathogenesis and memory decline in AD.

Abstract
BACKGROUND Epilepsy during pregnancy and puerperium is infrequent, and it can induce severe complications and poor prognosis. Pregnancy in women with epilepsy (WWE) is usually uneventful. Previous studies have mainly focused on the effects of different treatments on prognosis. However, few articles have addressed if different epilepsy types were associated with a higher incidence of seizure breakthrough/recurrence and pregnancy outcomes. METHODS In the present study, based on a unique sample with a low incidence of epilepsy, we evaluated the main clinical characteristics of epilepsy patients. RESULTS Mean age of pregnant WWE was 29.95±4.65 (range, 21-42) years. Pregnancies were at a mean gestational age of 33.80±9.14 (range, 7-41) weeks, and 88.24% (52/61) of WWE were in their third trimester. There was 9.84% (6/61) of pregnant WWE underwent abortion or induced labor in midpregnancy to ensure maternal safety. There was 75.41% (46/61) of pregnant WWE using antiepileptic drugs (AEDs), of which 52.46% (32/61) were taking a single AED and 22.95% (14/61) were using multiple AEDs. There was 47.54% (29/61) of WWE experiencing seizures during their pregnancy. We found that the type of epilepsy did not affect seizures during pregnancy or the prognosis. However, more pregnant WWE with hypertensive disorder had seizures compared with pregnant WWE without hypertensive disorder. CONCLUSIONS The study highlighted a novel direction for effectively improving seizures during pregnancy and the prognosis of pregnancy-associated epilepsy.

Abstract
BACKGROUND The effects of overweightness and weight loss on the development and prognosis of hepatocellular carcinoma (HCC) remain unclear. In this study, we aimed to evaluate the impact of overweightness and weight loss on the survival of patients with intermediate/advanced HCC receiving chemoembolization as initial treatment. METHODS We examined 1,170 patients who underwent chemoembolization as initial treatment for Barcelona-Clínic Liver Cancer stages B and C HCC at Sun Yat-sen University Cancer Center (Guangzhou, China) between December 2009 and May 2015. A baseline body mass index (BMI) of ≥23 kg/m2 was defined as overweight, and body-weight loss of ≥5.0% from baseline was defined as critical weight loss (CWL). Cox regression analysis was used to determine the association between overweightness or CWL and overall survival (OS). RESULTS The median survival time was 16.8 (95% confidence interval, 13.9-19.7) months and 11.1 (95% confidence interval, 10.0-12.2) months in the overweight and non-overweight groups (log-rank test, P < 0.001), respectively. Cox multivariate analysis identified overweightness as an independent protective prognostic factor for OS (P < 0.001). Subgroup stratification analysis revealed a significant association between overweightness and survival among patients receiving further treatment (P = 0.005), but not in those not receiving further treatment (P = 0.683). Multivariate analysis showed that both overweightness and CWL were independent prognostic factors for OS among patients receiving further treatment. CONCLUSION Among patients with intermediate- or advanced-stage HCC initially treated with chemoembolization, overweightness was associated with longer OS. Furthermore, CWL was an independent adverse prognostic factor for OS in patients receiving additional treatment.

Abstract
From 1987 to 2017, cardiovascular disease (CVD) had been ranking the first cause of death in Suzhou, and the mortality rate showed an upward trend annual percentage changes (APC=0.62%, P=0.001), while the standardized mortality rate showed a downward trend (APC=-2.65%, P<0.001). The probability of premature death of CVD declined consistently from 7.06% in 1987 to 2.00% in 2017 (APC=-4.45%, P<0.001). When the life expectancy was set at 70, the potential years of life lost rate (PYLLR) decreased from 6.35‰ in 1987 to 3.30‰ in 2017, and the standardized PYLLR decreased from 7.30‰ to 2.68‰. When the life expectancy was set at 75, the PYLLR decreased from 10.12‰ to 5.19‰, and the standardized PYLLR decreased from 11.44‰ to 3.88‰. With the increase of years, all PYLLR and standardized PYLLR showed a significantly downward trend (APC=-2.51%--3.89%, P<0.001).

Abstract
Introduction
The pathophysiology of HFpEF is complicated and treatments that improve outcomes in HFrEF have no substantial benefits in HFpEF. Impairments in LV global longitudinal strain (GLS) and LV diastolic function parameters have been regarded as novel echocardiographic markers to predict cardiovascular events in HFpEF. Preliminary trials indicate that iloprost, an inhaled prostacyclin analougue, improves exercise hemodynamics in both patients with pulmonary artery hypertension and pulmonary hypertension associated with HFpEF.
Purpose
We aim to investigate the impact of inhaled iloprost on LV global longitudinal strain, LV diastolic function and RV function during exercise in HFpEF population.
Methods
34 patients diagnosed with HFpEF were included with exclusion of severe pulmonary, coronary artery, valvular heart and pericardial diseases. Subjects were randomized 1:1 to inhalation of iloprost or placebo. Transthoracic echocardiography was performed at rest and after 6-minute supine bicycle exercise at 20-Watt workload. We utilized tissue speckle tracking by QLAB software to derive LV GLS and global strain rate during LV isovolumetric relaxation period (SRIVR). E/e', E/SRIVR, tricuspid regurgitation pressure gradient (TRPG), tissue Doppler imaging of RV lateral tricuspid annulus and tricuspid annular plane systolic excursion (TAPSE) were measured to evaluate changes of myocardial performance.
Results
LV GLS during exercise significantly enhanced after iloprost use. E/SRIVR, a novel predictor of LV filling pressure, was significantly decreased. E/e' was also lower in iloprost group by trend. Improvements in RV function and degree of pulmonary hypertension during exercise with iloprost were observed in this study.

Effects of iloprost at rest and exercise
Conclusions
Our study is the first to demonstrate that, in patients with HFpEF, inhaled iloprost favorably enhances LV GLS reserves, decreases LV diastolic filling load, reduces pulmonary hypertension and thereby improves RV function during exercise.

Abstract
OBJECTIVE To evaluate the sero-positivity of Babesia infection in voluntary blood donors in Jiangsu region, so as to provide the evidence for transfusion safety. METHODS A total of 950 blood samples were collected from voluntary blood donors in Jiangsu Provincial Blood Center from February to May, 2017, and detected by double antigen sandwich ELISA targeting peptides derived from B. microti-secreted antigen 1 (BmSA1). The positive samples were confirmed by microscopy and nested-PCR to determine parasitemia. The prevalence of anti-BmSA1 was analyzed between/among different genders, ages and occupations of the blood donors. RESULTS Of the 950 blood screened samples, 5 were positive for anti-BmSA1, and the sero-prevalence of Babesia infection was 0.53%. The 5 samples were all negative by microscopy and nested-PCR. There were no gender- (χ2 = 0.01, P =0.92) or age-specific differences (χ2 = 0.11, P = 0.95) in the sero-prevalence of Babesia infection; however, there was an occupation-specific difference detected in the sero-prevalence of Babesia infection (χ2 = 11.93, P < 0.05). CONCLUSIONS Babesia infection is detected in voluntary blood donors in Jiangsu region, which should be paid much attention.

Abstract
In order to facilitate the treatment strategies for biliary tract injury, hilar cholangiocarcinoma, bile duct tumor thrombus, cholangiocellular carcinoma and bile duct cystic dilatation, many classifications have been made, even more than 10 types for one disease. Each type is represented by numbers or English alphabet, which are not only confusing but also difficult to remember. The Academician Mengchao Wu divided the liver into five sections and four segments base on its anatomy, this classification is very direct and visual, thus had been using till now. In order to overcome those complicated problems, it is considered to develop a new classification based on actual anatomic location similar to that for liver cancer, which is easy to remember and to directly determine the treatment strategy. All kinds of classifications have their own characteristics and advantages and disadvantages. This practical classifications avoid the complexity and may be useful for clinicians.

Abstract
Applications of wavelet analysis in ultra-thin film transient reflectivity (TR) measurements have been investigated. Advantages of utilizing different localized wavelet bases, in position and time, have been addressed on the residual TR signals. Morse wavelets have been used to obtain information from the abrupt oscillatory modes in the signal, which are not distinguishable with conventional methods such as Fourier transforms. These abrupt oscillatory modes are caused by the surface, interface, or any short-lived oscillatory modes which are suppressed in the TR signal in ultra-thin films. It is demonstrated that by choosing different Morse wavelets, information regarding different oscillatory modes in the TR signal of a heterostructure thin film is achievable. Moreover, by performing wavelet analysis on multiferroic heterostructures, oscillatory modes with very close energy ranges are easily distinguishable. For illustration, residuals of the TR signals have been obtained by a pump-probe setup in reflectivity mode on La0.7Sr0.3MnO3/SrTiO3 and BaTiO3/La0.7Sr0.3MnO3/SrTiO3 samples, where sufficient signal to noise ratios have been achieved by taking multiple scans. The residual signals have been analyzed with Morse wavelets, and multiple oscillatory modes with close energy ranges have been observed and distinguished. This approach can isolate the location of various oscillatory modes at the surface, interface and in the bulk of the heterostructure sample.

Abstract
OBJECTIVES To analyze the characteristics of medical malpractices in orthopaedic surgeries, to explore principles and methods in medical legal identification, and to provide basic data for uniform medicolegal standard for the future medical identification. METHODS A retrospective analysis was conducted on 100 cases of medical malpractices in orthopaedic surgery, among the 364 cases archived in Medicolegal Expertise Center of Xi'an Jiaotong University during 2002-2015. RESULTS In the 100 cases of orthopedic medical malpractices, with 104 hospitals involved in, 95 cases were judged with medical errors and the other 9 cases with no error. The top 3 reasons for errors were (1) inadequate observation or estimation of diseases (27.9%), (2) intraoperative improper operation (17.3%), and (3) delayed or missed diagnosis and treatment (12.5%). The consequences of medical malpractices were mostly disability (61%), followed by prolonged diseases (31%) and death (8%). With regard to the causal relationship between medical errors and consequences, 95 cases (91.4%) were with causality and the other 9 cases (8.6%) with no causality. Specifically, 56 cases (53.9%) were with medical errors as the secondary causes accounting for 25% causative potency, and 20 cases (19.2%) were with medical errors as the major causes accounting for 75% causative potency. CONCLUSIONS It is pivotally important for determining the causative potency of medical errors to analyse the causes of damages in orthopaedic surgery and to distinguish subjective factors from objective ones of medical errors.

Abstract
Background: Hepatic caudate lobectomy is considered to be a technically difficult surgery because of the unique anatomy and deep location of the hepatic caudate lobe. Here, we assessed the technical feasibility and safety of robotic partial caudate lobectomy using the da Vinci® Surgical System and compared it with traditional open/laparoscopic surgery.Material and methods: Six patients diagnosed with liver cancer (primary liver cancer, 5; metastasis of breast cancer, 1) who underwent caudate lobectomy were prospectively enrolled. Two patients underwent robotic surgery, one underwent laparoscopic surgery, and three underwent traditional/open surgery. Surgical procedure, recovery, and characteristics of robotic surgery were noted and compared with other approaches.Results: All surgeries were successfully completed, and no serious postsurgical complications were observed. In the robotic group, the time taken to complete the surgery and the estimated intraoperative bleeding were 150 and 90 min and 50 and 100 ml in patient 1 and patient 2, respectively. The patients were able to tolerate fluid diet on the following postsurgical day. These two patients had no postsurgical complications and were discharged from the hospital on days 5 and 6 after recovery, respectively. Pathologically, the margins of specimens obtained from these two patients were tumor-free (R0 resection). Tumor size in the traditional/open group was larger than that in the robotic and laparoscopic groups. Blood loss in the laparoscopic case was 50 ml and was less than that in the traditional/open surgery cases (300, 2100, and 1500 ml).Conclusions: Robot-assisted partial hepatic caudate lobectomy is a technically feasible surgery. Our study illustrated an advantage of robotic hepatic caudate lobectomy over laparoscopic or traditional/open surgery and suggested that da Vinci® minimally invasive hepatectomy is applicable in even more technically challenging anatomic locations.

Abstract
Objective: To investigate the prognostic risk factors of acquired immunodeficiency syndrome (AIDS) patients with pneumocystis pneumonia (PCP), and to establish risk models for predicting early outcome. Methods: The clinical data of 418 AIDS patients with PCP admitted to Department of Infectious Diseases, Beijing You'an Hospital, Capital Medical University from January 2008 to May 2016 were retrospectively analyzed.The patients were divided into death group and survival group according to clinical outcome during hospitalization.Data of the two groups were collected including general information and laboratory test results.Multivariate Logistic regression was used to analyze risk factors affecting prognosis of patients, establish prognostic models and evaluate predictive value of the model. Results: Of the 418 AIDS patients with PCP, 388 cases were male and 30 cases were female, aged from 5 to 82 years, mean age was (40±12) years.There were 82 patients in the death group and 336 patients in the survival group.Disease course, bacterial infection and alveolar-arterial oxygen pressure difference(P(A-a)O(2)), serum lactate dehydrogenase(LDH), white blood cell (WBC), neutrophil (N), alanine aminotransferase (AST), urea nitrogen (BUN) and serum potassium (K) were significantly higher in the death group than those in the survival group (all P<0.05), and arterial oxygen pressure (PaO(2)), blood oxygen saturation (SpO(2)), CD4(+) T lymphocyte count, lymphocyte (L) , hemoglobin (Hb), platelet (PLT), albumin (ALB), prealbumin (PALB), cholinesterase (CHE), cholesterol (CHO), serum chlorine (Cl) and serum sodium (Na) were significantly lower in the death group than those in the survival group (all P<0.05). Multivariate Logistic regression analysis showed that P(A-a)O(2, )ALB, LDH, N and CD4(+) T lymphocyte count were prognostic factors of AIDS complicated with PCP.Prognostic index=9.736+ 0.112×P(A-a)O(2)-0.719×ALB+ 0.006×LDH+ 0.355×N-0.021×CD4.ROC curve of the short-term prognostic model was 0.985 (95%CI 0.977-0.994), with P value 0.000, cut-off value 0.907, sensitivity 92.0% and specificity 98.8%.The mortality rate increased with the increase of equation value. Conclusions: P(A-a)O(2, )ALB, LDH, N and CD4(+) T lymphocyte count are independent risk factors to predict short-term prognosis in these patients.The short-term prognostic model based on independent risk factors is useful in guiding clinical treatment.

Abstract
PURPOSE Aerobic exercise improves prognosis and quality of life (QoL) following completion of chemotherapy. However, the safety and efficacy of aerobic exercise during chemotherapy is less certain. A systematic review was performed of randomised trials of adult patients undergoing chemotherapy, comparing an exercise intervention with standard care. METHOD From 253 abstracts screened, 33 unique trials were appraised in accordance with PRISMA guidance, including 3257 patients. Interventions included walking, jogging or cycling, and 23 were of moderate intensity (50-80% maximum heart rate). RESULTS Aerobic exercise improved, or at least maintained fitness during chemotherapy. Moderately intense exercise, up to 70-80% of maximum heart rate, was safe. Any reported adverse effects of exercise were mild and self-limiting, but reporting was inconsistent. Adherence was good (median 72%). Exercise improved QoL and physical functioning, with earlier return to work. Two out of four studies reported improved chemotherapy completion rates. Four out of six studies reported reduced chemotherapy toxicity. There was no evidence that exercise reduced myelosuppression or improved response rate or survival. CONCLUSIONS Exercise during chemotherapy is safe and should be encouraged because of beneficial effects on QoL and physical functioning. More research is required to determine the impact on chemotherapy completion rates and prognosis.

Abstract
A broadly accepted standard treatment for adult T-lymphoblastic lymphoma (T-LBL) has not yet been defined. To address that issue, we retrospectively compared three chemotherapy regimens used to treat 110 adult patients with newly diagnosed T-LBL. These included two adult regimens (ECOG2993 and hyper-CVAD) and a childhood regimen (BFM-90). These intensive drug regimens are mainly used to treat childhood and adult acute lymphoblastic leukemia. They included induction, consolidation, and maintenance chemotherapy protocols and were administered over the course of 2 years. Seventy-five patients (80%) achieved a complete remission (CR). Within a median follow-up time of 31 months (range: 5–152 months), the 5-year overall survival (OS) and progression-free survival (PFS) rates were 47.7% (95% CI, 35.0–69.8%) and 45.7% (95% CI, 27.6–56.6%), respectively. Shorter survival was associated with age > 40 years, poor ECOG PS and bone marrow involvement. Elevated lactic dehydrogenase (LDH) level, Ann Arbor stage and International Prognostic Index (IPI) score had no prognostic value. The childhood chemotherapy regimen improved CR and the overall survival rate more than the adult regimen in patients aged < 40 years.

Abstract
Objectives Meningioma recurrence remains a significant issue. No study has described the relationship between the clinical features and prognosis of communicating meningioma that primarily originates from the olfactory groove. The aim of the study was to identify prognostic factors of communicating olfactory groove meningiomas that could be stratified according to their risk of recurrence. Results A Simpson grade one or two resection was achieved. Complications with cerebrospinal rhinorrhoea occurred in two patients: one required reoperation, and the other was managed successfully with external drainage of lumbar cistern. There were 5 known clinical recurrences within the median follow-up of more than 5 years. The median 5-year recurrence-free survival for patients was 88.4%. Factors such as gender, tumour size, T2 signal and the hyperostotic bone had no significant effect on recurrence-free survival. However, recurrence was activated by oedema range, hyperostosis, dural tail sign and tumor texture (p < 0.05). Interestingly, female patients with the disease were younger than males at diagnosis, and the difference was statistically significant ( p = 0.013). Conclusions Based on these features of communicating olfactory groove meningiomas, different strategies may be adopted for the follow-up and subsequent treatment. Due to the relatively uncommon incidence, more investigations into the clinical behaviour of this entity are crucial. Patients and Methods A retrospective study of 43 patients harbouring olfactory groove meningiomas invading the ethmoid or nasal cavity was conducted at three medical centers from 2000 to 2010. The records were reviewed for clinical presentations, imaging studies, surgical observation, histological features and follow-up.

Abstract
Objective: To analyze the characteristics of immunoglobulin heavy chain complementarity-determining region (IgH-CDR3) repertoire of peripheral B cells in a patient with primary biliary cholangitis (PBC) and to investigate the diversity of the immune system. Methods: Arm-PCR was used to amplify the IgH-CDR3 region of circulating B cells isolated from a PBC patient, and high-throughput sequencing was used to analyze the amplified product. The characteristics of immune repertoire were analyzed by bioinformatics. Results: In total, 329219 sequence reads were generated from the sample, with 325540 total CDR3 sequences and 72774 distinct CDR3 sequences, and the D50 of IGH-CDR3 was 7.7. The dominant CDR3 length of the sample was 45 nt (9.6%); the N addition with the highest frequency ranged from 13 to 14 nt (5.25%); the J trimming with the highest frequency was 0 nt (12.7%); the three most frequent V alleles were V4-59 (9.5%), V3-23 (8.1%), and V1-69 (6.4%). Conclusion: The diversity of IgH-CDR3 repertoire is relatively low in this patient with PBC, with several B-cell clonal expansions. The specificity needs to be further verified after increasing the sample size.

Abstract
Objective: To investigate the clinical and laboratory features of patients with liver disease and positive anti-liver/kidney microsomal-1 (anti-LKM-1) antibody, and to provide a reference for clinical diagnosis and differential diagnosis. Methods: The clinical data of patients with positive anti-LKM-1 antibody who were treated in our hospital from 2006 to 2016 were collected, and clinical and laboratory features were analyzed and compared. An analysis was also performed for special cases. Results: The measurement of related autoantibodies was performed for about 100 thousand case-times, and 15 patients were found to have positive anti-LKM-1 antibody. Among the 15 patients, 7 were diagnosed with type 2 autoimmune hepatitis (AIH) with an age of 11.0 ± 9.0 years and were all adolescents with acute onset; 8 were diagnosed with hepatitis C with an age of 51.5 ± 9.0 years, among whom 7 were middle-aged patients and 1 was a child aged 12 years, and all of them had an insidious onset. Compared with the patients with hepatitis C, the AIH patients had significantly higher levels of alanine aminotransferase (1 003.9 ± 904.3 U/L vs 57.0 ± 84.1 U/L, P < 0.05), aspartate aminotransferase (410.7 ± 660.3 U/L vs 34.9 ± 42.9 U/L, P < 0.05), and total bilirubin (98.0 ± 191.0 μmol/L vs 15.4 ± 6.0 μmol/L, P < 0.05). There was a reduction in immunoglobulin G after the treatment with immunosuppressant, compared with the baseline. Of all 8 patients with hepatitis C, 6 received antiviral therapy with interferon and ribavirin, and 5 out of them achieved complete response, among whom 4 had a reduction in the level of anti-LKM-1 antibody after treatment; however, a 12-year-old child developed liver failure after interferon treatment and died eventually. Conclusion: Positive anti-LKM-1 antibody is commonly seen in patients with type 2 AIH or hepatitis C, but there are differences between these two groups of patients in terms of age, disease onset, liver function, and the level of anti-LKM-1 antibody. The hepatitis C patients with a confirmed diagnosis and exclusion of autoimmune hepatitis can achieve good response to interferon under close monitoring, even if anti-LKM-1 antibody is positive. As for adolescent patients with hepatitis C and positive anti-LKM-1 antibody, the possibility of AIH should be excluded.

Abstract
OBJECTIVE To explore the application of the technique of terminal branches portal vein embolization(TBPVE)for planed hepatectomy. METHODS From February 2016 to June 2016, 4 patients with hepatocellular carcinoma underwent TBPVE and liver resection in Yuebei People's Hospital (n=3) and Jiangxi Ji'an Central People's Hospital (n=1). All of them were male and were 50, 64, 39 and 47 years old respectively. All the tumors located in the right lobe. All patients had the liver function of Child-Pugh A classification and liver cirrhosis level of G2S4. The standard liver volume (SLV) were 1 291, 1 109, 1 177 and 1 242 ml and estimated future liver remnant(FLR) were 315, 347, 306 and 323 ml respectively. The puncture site of TBPVE was determined by the three-dimensional reconstruction of portal vein. Three patients were punctured in the segment Ⅵ and the other one punctured in the segment Ⅲ. CT scan was repeated 2 weeks after TBPVE and FLR and FLR/SLV were calculated. All patients underwent right hepatectomy 2 weeks after TBPVE. RESULTS On the 14(th) day after TBPVE, the FLR of 4 patients were 529, 462, 469 and 498 ml which increased 67.9%, 33.1%, 53.3% and 54.2% compared with that before TBPVE, and FLR/SLV were 41.0%, 41.7%, 39.8% and 40.1% respectively. No severe complication occurred. Right hepatectomy were performed 2 weeks after TBPVE. No inflow blood control applied during the liver resection. The mean blood loss was 950 ml and the mean operating time was 3.3 hours (ranging from 3 to 4 hours). One patient had respiratory infection and two had slight jaundice and ascites for a short period. No other complication occurred. CONCLUSION The TBPVE could induce a rapid and large FLR volume that give chances to patients with small FLR to have liver resection for hepatocellular carcinoma.

Abstract
Interleukin (IL)-17 has been reported to play a controversial role in tumor immunity. Our previous studies showed that infiltration of IL-17-producing cells in esophageal squamous cell carcinoma (ESCC) induced tumor protective immunity by recruiting CD8+T lymphocytes, natural killer (NK) cells, and B lymphocytes into the tumor microenvironment. However, the mechanism of IL-17 regulation of tumor-associated neutrophils remains elusive in ESCC. In this study, we therefore evaluated the accumulation of myeloperoxidase (MPO)+ neutrophils and its association with IL-17-producing cells within ESCC tumor nests. We also investigated the effects of IL-17 on the recruitment and antitumor activity of neutrophils. MPO+ neutrophil infiltration was found to predict a favorable prognosis in ESCC patients and was positively correlated with IL-17+ cell density. IL-17 stimulated ESCC tumor cells to release more of the CXC chemokines CXCL2 and CXCL3, which are involved in neutrophil migration. Furthermore, IL-17 potentiates the direct killing capability of neutrophils by enhancing the production of cytotoxic molecules, including reactive oxygen species (ROS), MPO, TNF-related apoptosis-inducing ligand (TRAIL), and IFN-γ. Experiments in mice suggested that IL-17 alone might not affect tumor progression in the tumor-bearing host, but IL-17 can inhibit tumor growth by promoting beneficial neutrophil infiltration and activation at tumor sites. As emerging evidence indicates that targeting tumor-associated neutrophils is a strategy for antitumor therapy, our findings reveal a positive contribution of IL-17 to the modulation of neutrophil-mediated antitumor immunity in ESCC. This study provides further understanding of the mechanisms that selectively regulate functional activities of neutrophils, which may be critical for developing new tumor immunotherapy.

Abstract
Background In this study, we aimed to investigate the impact of surgical procedures on the body image of head and neck cancer patients treated with radiotherapy and with or without radical surgery. Methods A cross-sectional survey of 150 patients with head and neck cancer was conducted. Sixty patients had nasopharyngeal cancer treated with definitive radiotherapy without surgery, and 90 patients had oral cavity cancer treated with radical surgery plus adjuvant radiotherapy. All participants completed a 10-item Body Image Scale (BIS) questionnaire to assess body image dissatisfaction. Among all patients, the socio-demographic and clinical variables were age, gender, partnership, education, employment, and radical surgery. In surgically-treated patients, the clinical variables were facial skin sacrificed, mouth angle sacrificed, glossectomy, maxillectomy, and mandibulectomy. ANOVAs, t-tests, and multiple regressions were used to evaluate the relationships between these variables and BIS results. Results In all patients, radical surgery was the strongest independent predictor of BIS scores. Surgically-treated patients had significantly worse BIS scores than the patients without surgery. In surgically-treated patients, facial skin sacrificed, mouth angle sacrificed, maxillectomy, and mandibulectomy were significantly associated with body image. According to multivariable analyses, inferior maxillectomy and segmental mandibulectomy were independent prognosticators of a poor BIS score in surgically-treated patients. Conclusion Radical surgery for head and neck cancer patients has a significant impact on their body image, especially for those undergoing facial bone destructive surgery.

Abstract
The relevance of antiphospholipid (aPL), antinuclear (ANA) or antithyroid (ATA) antibodies in women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) are controversial. The present study aims to investigate which autoantibodies are associated with the pregnancy outcome of patients undergoing first IVF/ICSI treatment. A total of 3763 IVF/ICSI patients were recruited from January to December 2015. Forty-five patients positive for aPL presenting adverse outcomes in their first cycle received low-dose aspirin treatment before the second transfer. Logistic regression analyses were performed to assess any association between autoantibodies and IVF/ICSI outcomes. The aCL-IgG was significantly associated with live birth rate (OR 0.58, 95% CI 0.36-0.96, p<0.05) and miscarriage rate (OR 2.04, 95% CI 1.23-3.40, p<0.01). The aCL-IgM was associated with miscarriage rate (OR 2.14, 95% CI 1.29-3.54, p<0.01). The aβ2GPI-IgG was associated with implantation rate and clinical pregnancy rate (OR 0.61, 95% CI 0.24-0.96, p<0.05; OR 0.40, 95% CI 0.13-0.87, p<0.05, respectively). After the low-dose aspirin treatment, the live birth rate (37.0% vs. 19.1%, p<0.05) increased significantly in patients with positive for aPL. In contrary, the aβ2GPI-IgM, ANA, anti-thyroglobulin (aTG) and anti-thyroperoxidase (aTPO) antibodies had no association with IVF/ICSI outcome. It is suggested that the presence of aCL-IgG, aCL-IgM and aβ2GPI-IgG might exert a detrimental effect on IVF/ICSI outcomes. Low-dose aspirin treatment could be useful for patients positive for these antibodies. Therefore, it is suggested that these antibodies should be assessed prior to IVF/ICSI treatment.

Abstract
Native T1 value is emerging as a reliable indicator of abnormal heart conditions related to myocardial fibrosis. Investigators have extensively used the standardized myocardial segmentation of the American Heart Association (AHA) to measure regional T1 values of the left ventricular (LV) walls. In this paper, we present a fully automatic system to analyze modified Look-Locker inversion recovery images and to report regional T1 values of AHA segments. Ten healthy individuals participated in the T1 mapping study with a 3.0 T scanner after providing informed consent. First, we obtained masks of an LV blood-pool region and LV walls by using an image synthesis method and a layer-growing method. Subsequently, the LV walls were divided into AHA segments by identifying the boundaries of the septal regions and by using a radial projection method. The layer-growing method significantly enhanced the accuracy of the derived myocardium mask. We compared the T1 values that were obtained using manual region of interest selections and those obtained using the automatic system. The average T1 difference of the calculated segments was 4.6 ± 1.5%. This study demonstrated a practical and robust method of obtaining native T1 values of AHA segments in LV walls.

Abstract
For the treatment of stage III/IV malignant melanoma (MM), a network meta-analysis (NMA) was conducted to compare the short and long-term efficacy of targeted therapy with single or double-drug regimens. All conducted randomized controlled trials (RCTs) searched from PubMed and Cochrane Library were included in the study for direct and indirect comparison for MM. The odds ratio (OR) and surface under the cumulative ranking curves (SUCRA) value of the targeted therapy with single or double-drug regimens for treatment of stage III/IV MM were also analyzed. To group the treatments according to their similarity with regards to both outcomes, cluster analyses were performed. Ultimately, 16 RCTs were incorporated for this NMA. The NMA revealed that the overall response rate (ORR) values of single-drug regimens (Vemurafenib [Vem], Dabrafenib [Dab], and Nivolumab [Niv]) were higher than those of Dacarbazine (Dac). Also the ORR values of double-drug regimens (Dab + Trametinib [Dab + Tra], Niv + Ipilimumab [Niv + Ipi], and Vem + Cobimetinib [Vem + Cob]) were moderately higher than those of Dac. The results of the SUCRA showed that short-term efficacy of single-drug regimens (Vem and Dab) were better, while the short-term efficacy of double-drug regimens (Dab + Tra and Vem + Cob) were relatively better. It was determined that Vem, Dab, and Niv might be the best choice in evaluating the treatment of stage III/IV MM among different single-drug targeted therapy regimens, while Dab + Tra, Niv + Ipi, and Vem + Cob might have better short-term efficacy among different double-drug targeted therapy regimens.

Abstract
Inhibitor of DNA-binding protein 3 (Id3) is required for tumor angiogenesis and regulatory T-cell generation. However, the involvement of Id3 in unexplained repeated implantation failure (RIF) and recurrent miscarriage (RM) remains poorly understood. Immunohistochemistry was used to identify Id3, CD34, CTLA-4, and FOXP3 in the endometrium taken from the women with RIF (n=16), RM (n=16) and matched controls (n=8). The images were acquired and analyzed by the Vectra® automated quantitative pathology imaging system. Percentage of Id3+ cells was significantly higher in the endometrium of women with RIF and RM compared with controls. The numbers of Id3+ and CD34+ vessels in the endometrium were positively correlated in control but not in RIF or RM. Percentages of CTLA-4+ cells, but not FOXP3+ cells, were significantly increased in the endometrium of RIF and RM women than those in controls. We found aberrant expressions of endometrial Id3 and CTLA-4 in peri-implantation endometrium of women with RIF and RM, suggesting the negative roles of these angiogenesis and immune tolerance markers involving in regulating endometrium receptivity.

Abstract
Objective: To research the regulation effects of Krüppel like zinc finger transcription factor 2 (KLF2) on γ-glutamylcysteine synthetase (γ-GCS) in airway epithelial cells of chronic obstructive pulmonary disease (COPD). Methods: (1) Human specimen experiment: lung tissue of pulmonary lobectomy patients with lung cancer with or without COPD was collected from Department of Thoracic Surgery of Hunan Cancer Hospital from December 2008 to December 2009. The patients were divided into COPD group and control group without COPD. The levels of KLF2, γ-GCS mRNA and protein expression in lung tissues were measured by immunohistochemistry and in situ hybridization (ISH). Then, the correlation between KLF2 and γ-GCS mRNA and protein expression levels were analyzed, as well as the correlation between KLF2 or γ-GCS protein and smoking index, percentage of forced expiratory volume in one second to predicted value (FEV1%), percentage of forced expiratory volume in one second to forced vital capacity (FVC/FEV1). (2) Animal experiment: the primary bronchial epithelial cells of rats were extracted by enzyme digestion. After 6 hours of incubation with 10% tobacco smoke extract (TSE), cellular glutathione (GSH) was measured by enzyme linked immunosorbent assay (ELISA) method. The cells were transfected by specific inhibitor of KLF2 through the liposom, which inhibited the protein expression of KLF2. Then, the cells were divided into KB group (blank control group without any treatment), KB+ TSE group (treated with TSE), NC group (control group transfected with miRNA), NC+ TSE group (treated with miRNA and TSE), 92a group (transfected with KLF2 inhibitor), 92a+ TSE group (treated with KLF2 inhibitor transfection and TSE) based in the treatment. After that, the changes of KLF2 and γ-GCS mRNA and protein expression in the cells of each group were measured by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot method. Results: (1) Human specimen experiment: The expressions of KLF2 mRNA, protein and γ-GCS mRNA, protein in the lung tissue of COPD patients were strong positive and higher than those in control group (0.32±0.04 vs 0.19±0.03, 0.35±0.05 vs 0.22±0.03; 0.28±0.03 vs 0.16±0.03, 0.31±0.05 vs 0.21±0.03; all P<0.01). Linear correlation analysis showed that KLF2 mRNA and protein were positively correlated with γ-GCS mRNA and protein (r=0.705, 0.722; both P<0.01). The KLF2 and γ-GCS protein were positively correlated with smoking index, FEV1% and FEV1/FVC (r=0.552, 0.728, 0.670, and r=0.631, 0.727, 0.657; all P<0.01). (2) Animal experiment: The level of GSH in KB+ TSE group was significantly higher than that in KB group[(28.05±2.04) vs (7.27±0.33) nmol/mg, P<0.01]. The KLF2 mRNA, protein and γ-GCS mRNA, protein in KB+ TSE group (1.715±0.026, 1.842±0.028 and 2.117±0.067, 1.879±0.065) were higher than those in KB group (1.130±0.017, 1.177±0.033 and 1.378±0.053, 1.177±0.042; all P<0.05), and those in 92a group (0.472±0.028, 0.634±0.025 and 0.582±0.025, 0.554±0.021) were significantly lower than those in KB group, NC group (1.047±0.056, 1.092±0.045 and 1.303±0.037, 1.252±0.037), and those in TSE+ 92a group (0.262±0.017, 0.288±0.017 and 0.337±0.022, 0.321±0.022) were significantly lower than those in KB+ TSE group, 92a group and NC+ TSE group (1.576±0.036, 1.646±0.066 and 1.948±0.093, 1.843±0.078) (all P<0.05). Conclusion: KLF2 exerts antioxidative effect by regulating the expression of γ-GCS in the bronchial epithelial cells of chronic obstructive pulmonary disease.

Abstract
PROBLEM Human chorionic gonadotropin (hCG) and regulatory T cells (Tregs) have been suggested to play important roles during the initial stage of pregnancy. However, the clinical relevance and mechanism of the effects of hCG on Treg functions in women with recurrent implantation failure (RIF) remain to be elucidated. METHOD OF STUDY Thirty-four RIF and twenty-three control women were included in the study. Endometrial and peripheral Tregs were analyzed by immunohistochemistry and flow cytometry, respectively. Tregs were generated from naïve CD4+ T cells by stimulation with anti-CD3/CD28 in the presence or absence of hCG, and the subsets were analyzed by flow cytometry, Western blotting, and qPCR. RESULTS The percentages of endometrial FOXP3+ Tregs and peripheral CCR4+ FOXP3+ Tregs were significantly lower in the women with RIF than in the healthy controls. In addition, the percentages of CCR4+ FOXP3+ Tregs and TGF-β-expressing FOXP3+ Tregs were increased following the stimulation of naïve CD4+ T cells with anti-CD3/CD28, and these increases were concomitant with AKT and ERK dephosphorylation. CONCLUSIONS The results of this study provide novel evidence supporting a role of hCG in regulating the differentiation of peripheral FOXP3+ Tregs. The alterations of circulating Tregs may positively affect the pregnancy outcomes of patients with a history of RIF.

Abstract
PROBLEM We aimed to investigate the modulatory effects of vitamin D on peripheral blood cellular immune response in patients with recurrent miscarriage (RM). METHOD OF STUDY The effect of vitamin D on the number of peripheral blood cells, T helper 1 (Th1) cytokines, and NK cytotoxicity was measured in 99 women with RM. RESULTS The percentage of CD19+ B cells and NK cytotoxicity at an effector-to-target cell (E:T) ratio of 50:1, 25:1, and 12.5:1 were significantly higher in the vitamin D insufficiency group (VDI) than in the vitamin D normal group (VDN) (P<.05 each). The proportion of TNF-α-expressing Th cells was significantly higher in the vitamin D deficiency group (VDD) than in VDN (P<.05). However, there were no significant differences between VDI and VDD. This dysregulation was significantly reduced with 1,25(OH)2 D supplementation. CONCLUSION The data suggest that the abnormalities of cellular immune response were observed in RM patients with a low vitamin D level, which could be regulated to some extent with 1,25(OH)2 D supplementation.
