Abstract
Abstract
Background
Mood disorders, depression, and loneliness are known risk factors for thrombotic occlusions. Social relationships in general, and marital status in particular may play a role in predicting cardiovascular outcomes and survival after ST-segment elevation myocardial infarction (STEMI), but the evidence is inconclusive, especially in Asians. We sought to analyze clinical outcomes following AMI according to insurance type and living type.
Methods
From July 2016 to Sept 2018, the Korean Registry of Regional Cardiocerebrovascular Center for Acute Myocardial Infarction database collected patients over 18 years old who suffered AMI. 3 months and 1-year all-cause death, CVA and re-MI (composite endpoint) were collected by telephone interview.
Results
Overall, the total of 463 all-cause death and 113 re-MI occurred. At 3-months, each group did not any differences in all-cause death and re-MI. At 1-year, however, the single & medical aid patients exhibited significantly higher all-cause death (6.8% vs 18.3%; p=0.000) and composite endpoint (12.5% vs 20.6%; p=0.000) compared to the live together & health insurance.
Conclusion
Social and economic status may be linked to 1-year all-cause death in Korean patients with ST-segment elevation myocardial infarction.

Abstract
AIMS A novel quantitative method for rapid Newcastle disease virus (NDV) antibody detection was developed based on an innovative gold immunochromatographic assay with a quantitative immunosensor. METHODS AND RESULTS NDV antibody-detecting test strips containing a two-reaction system and double-test lines (T1, T2) were prepared. The test results were judged according to the signal ratio between the test and control lines as measured by the quantitative immunosensor. The minimum detection limit of the test strips for NDV antibodies was 22 titres. In addition, the assay was highly specific because only NDV antibodies produced visible test lines on the strip. The clinical application of the strips was tested by detecting NDV antibodies in 506 serum samples collected from chickens. The results showed a coincidence of 92·49% with those of the haemagglutination inhibition assay. CONCLUSIONS The strips were successfully prepared and showed high specificity towards NDV, sensitivity and stability. SIGNIFICANCE AND IMPACT OF THE STUDY This study describes a new method for detection of NDV antibody and provides a reference basis for rapid and quantitative monitoring of NDV antibodies. This new method overcomes the limitation of the existing colloidal gold immunochromatography, which only produces qualitative or semi-quantitative results.

Abstract
Abstract Objective To explore the application value of interleukin-33 (IL-33) in wound age estimation in forensic practice by observing the sequential changes of IL-33 after skin wound. Methods Skin wound models were generated on the back of mice with a round file of 5 mm in diameter. Skin samples of the same size were taken from the same parts of mice in control group and injury group 1 h, 3 h, 6 h, 12 h, 1 d, 3 d, 5 d, 7 d and 10 d after skin wound. Hematoxylin-eosin (HE) staining method was applied to observe the morphological changes in the recovering process after skin wound. Western blotting, immunohistochemistry staining and double immunofluorescence staining methods were applied to detect the expression changes of IL-33 in the skin wound samples. Results The results of Western blotting showed that the expression of IL-33 protein decreased slightly at 3 h after skin wound, increased gradually at 6 h after skin wound, and reached the peak value at 3 d, then decreased gradually. Immunohistochemistry staining results showed that faint positive expression of IL-33 was observed in epidermis, hair follicles, sebaceous glands and dermal resident cells of the control group skin. The positive cell rate of IL-33 increased at 3 h after skin wound and reached the peak value at 3 d, then decreased gradually. The results of double immunofluorescence staining showed that the majority of IL-33 positive cells from 1 d to 3 d after wound were macrophages, while the majority of IL-33 positive cells from 5 d to 7 d after wound were myofibroblasts. In addition, the results of HE staining showed that the wound healing process of the skin wound model was consistent with the pathological development law of inflammation. Conclusion IL-33 could become a reference index for wound age estimation of skin wound in forensic practice.

Abstract
Objective: To evaluate the feasibility, safety and efficacy of robotic-assisted lateral lymph node dissection for mid-low advanced rectal cancer. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) age between 18 and 80 years old; (2) rectal adenocarcinoma diagnosed by pathology; (3) without distant metastasis by preoperative CT or MRI; (4) patients underwent robotic-assisted total mesorectal resection (TME). Exclusion criteria: (1) conversion to open surgery; (2) multiple primary tumors; (3) patients underwent combined multiple organ resection. According to the above criteria, 137 patients undergoing robotic-assisted mid-low rectal cancer resection in the First Affiliated Hospital of Xi'an Jiaotong University from December 2016 to April 2019 were enrolled. Ninety-seven cases underwent robotic-assisted total mesorectal excision (TME group) and 40 underwent robotic-assisted total mesorectal resection with lateral lymph node dissection (LLND) (TME+LLND group, pelvic LLND was performed with neurovascular guidance to retain pelvic autonomic nerves in the order of the left side the first and then the right side). The propensity score matching of 1:1 was performed with R software, based on age, sex, BMI, ASA classification, distance from tumor to the anal verge, preoperative chemoradiotherapy history, preoperative abdominal surgery history, the size of tumors and TNM stage. The operative indicators, postoperative recovery, pathology and postoperative complications within 30 days were compared between the two groups. Results: A total of 72 cases were successfully matched (36 in each group), and there were no statistically significant differences in baseline data between the two groups (all P>0.05). The operation time of TME+LLND group was significantly longer than that of TME group [275.0 (180-405) minutes vs. 220.0 (140-320) minutes, Z=-3.680, P<0.001], while there were no statistically significant differences in blood loss during operation, time to postoperative first flatus, postoperative hospital stay, total hospital cost, tumor differentiation, and distal resection length of margin (all P>0.05). Circumferential resection margin was all negative in both groups. The number of harvested lymph modes in the TME+LLND groups was higher than that in the TME group [26 (18-37) vs. 14 (9-36), Z=-6.407, P<0.001]. In addition, there were no statistically significant differences in postoperative morbidity and Clavien-Dindo classification of complication within 30 days between the two groups (both P>0.05). Conclusions: Although robotic lateral lymph node dissection requires longer operation time, it is a feasible, safe and effective procedure.

Abstract
Abstract Objective To discuss the application value of CT scanning technology in cause of death determination of medical dispute cases. Methods From July 2017 to December 2018, postmortem CT imaging data of 12 medical dispute cases were collected. CT imaging diagnosis results and anatomy findings as well as differences between antemortem and postmortem CT diagnosis were compared. The advantages and disadvantages of CT routine tests of the cadavers in terms of the diagnosis of disease and damage were analyzed. Results The comparison between CT imaging diagnosis and anatomical findings showed that CT scans had advantages in the diagnosis of disease and damage with large differences in density changes, such as atelectasis, pneumonia, calcification, fracture and hemorrhage, etc. The comparison of CT diagnosis in antemortem and postmortem examination showed that the cadavers of medical dispute cases were well preserved and that postmortem CT scan was meaningful for the diagnosis of antemortem diseases. Conclusion Virtual anatomy technology has a relatively high application value in postmortem examination of medical dispute cases. It can provide effective information for the appraisers before the autopsy and can also provide a reference for cause of death analysis when the anatomy cannot be performed.

Abstract
BACKGROUND AND PURPOSE There are conflicting reports on the association between daytime napping and incident stroke. This study was designed to investigate the relationship between daytime napping and stroke within a community-based cohort. METHODS The present prospective study was based on the Sleep Heart Health Study. Napping habits were assessed with a self-reported Sleep Habits Questionnaire. Participants with napping habits of different durations and frequencies were followed up until the first stroke occurred or the final censoring date. Cox proportional hazards models were used to estimate the relationship between napping habits and stroke. RESULTS A total of 4757 participants (2219 men, mean age 63.6 ± 11.1 years) were enrolled in this study. Compared with those taking no naps, multivariate proportional hazards models analysis indicated that individuals taking naps with a duration of >60 min [hazard ratio (HR), 2.460; 95% confidence interval (CI), 1.538-3.934] had a higher risk of stroke. There was also an increased risk of stroke among participants taking naps daily (HR, 1.563; 95% CI, 1.059-2.307) or five to six times/week (HR, 1.548; 95% CI, 1.026-2.335). After combining napping durations and frequencies, regular long naps (HR, 1.903; 95% CI, 1.182-3.065) and regular short naps (HR, 1.451; 95% CI, 1.010-2.084) were independent risk factors for incident stroke. CONCLUSION Daytime napping with a long duration (>30 min) or a high frequency (≥5 times/week) may increase the risk of stroke.

Abstract
OBJECTIVES Swallowing disorder is a health burden for the elderly in China. This study aimed to investigate the prevalence of dysphagia and to test the association between skeletal muscle strength and swallowing problems among community-dwelling older adults. DESIGN A cross-sectional study. SETTING Community-dwelling Chinese elderly in China. PARTICIPANTS 3361 adults aged 65 years or above were involved, among which 1740 (51.8%) were female, with average age of 72.64 (Standard deviation, SD=6.10) years old. MEASUREMENTS Handgrip strength (HGS) was used to evaluate skeletal muscle strength. Dysphagia assessment was performed using the Eating Assessment Tool-10 (EAT-10) and the 30mL water swallow test (WST). Binary logistic regression was used to evaluate the relationship between skeletal muscle strength and dysphagia, and covariates as age, gender, material status, etc. were adjusted. RESULTS The prevalence of dysphagia were 5.5% and 12.9%, screened by EAT-10 and 30mL WST respectively. Participants with dysphagia showed lower HGS (21.73 ± 9.20 vs. 25.66 ± 11.32, p<0.001, by EAT-10; 20.26 ± 9.88 vs. 26.22 ± 11.28, p<0.001, by WST). The adjusted model suggested that muscle strength is a protective factor for swallowing disorders (adjusted OR=0.974, 95%CI: 0.950-0.999, by EAT-10; adjusted OR=0.952, 95%CI: 0.933-0.972, by WST). Subgroup analyses of WST found the effects were significant among participants aged in 70-74 years group and ≥75 years group, rather than those aged under 70. CONCLUSION Dysphagia was significantly associated with skeletal muscle strength among the community-dwelling elderly population. Effective interventions should be taken to manage the decline of muscle strength for the older adults, especially early prevention before 70 years old.

Abstract
In this study, a novel polysaccharide was isolated from Artemisia ordosica by water-extraction-ethanol-precipitation method. The optimal extraction conditions of Artemisia ordosica polysaccharide (AOP) were determined by single factor investigation and response surface methodology optimization, and were shown as follows: a liquid–solid ratio of 15.4 : 1 mL g−1, extraction time of 4.3 h, extraction temperature of 60 °C. Under the optimal conditions, the extraction yield and the sugar content of the AOP were 5.56% and 52.65%. Gel permeation chromatography coupled to multi-angle laser light scattering, a refractive index detection system and ion-exchange chromatography were used to determine the characterization of AOP. These results indicated that AOP, with a molecular weight of 2.1 kDa (62.6%) and 1.5 kDa (37.4%), had narrow polydispersity and rod conformations, and was composed of arabinose, galactose, glucose, xylose, mannose, galacturonic acid and glucuronic acid with molar ratio of 6.87 : 10.67 : 54.13 : 2.49 : 18.37 : 4.83 : 2.64 : 2.64. In addition, AOP exerted antioxidant ability in vitro and in vivo (rats). Moreover, AOP significantly modulated the composition of cecal microbiota population. Therefore, AOP is expected to be a functional ingredient for health improvement through improving antioxidant ability and modulating gut health. Artemisia ordosica polysaccharide is expected to be functional ingredient for health improvement through improving antioxidant ability and modulating gut health.![]()

Abstract
Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. The mortality rate of in-hospital patients whose conditions are complicated by sepsis remains high in spite of intensive-care treatment, therefore placing a significant financial burden on the health care system. In recent years, progranulin (PGRN), a cysteine-rich secretory protein (CRISP), has been found to play a crucial role in sepsis. PGRN participates in the pathogenesis of sepsis via diverse pathways, including bacterial clearance, cell growth and survival, tissue repair, and the regulation of inflammation. PGRN knockout mice suffer from serious infectious processes, whereas therapeutic administration of recombinant PGRN to such mice enhances bacterial clearance and reduces organ injury and mortality rate. Even though PGRN plays an important role in regulating sepsis, its potential mechanisms have not been completely clarified. In this review, we summarize the most recent research advances in the study of PGRN and its role in sepsis.

Abstract
OBJECTIVE This study aims to investigate the regulatory role of p38 mitogen-activated protein kinase (p38MAPK) in rats with lower-extremity arterial ischemia-reperfusion injury. MATERIALS AND METHODS A total of 60 Sprague-Dawley (SD) rats were randomly divided into four groups: control group (Group A), lower-extremity arterial ischemia-reperfusion group (Group B), lower-extremity arterial ischemic postconditioning group (Group C), and lower-extremity arterial ischemic postconditioning + SB203580 group (Group D, 5 μmol/L SB203580, the inhibitor of MAPK pathway, was injected after lower-extremity arterial ischemic postconditioning). The lower-extremity arterial vessels were collected after 24 h. The apoptosis in the lower-extremity arterial vessel in each group was detected via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) method. The expression of phosphorylated (p)-p38MAPK was measured via Western blotting, and the level of p-activating transcription factor-2 (ATF-2) was detected via immunohistochemical method. RESULTS The positive rate of apoptotic cells (%) in Group B was significantly increased compared to that in Group A (p<0.05). However, the positive rate was statistically decreased by postcondition in Group C, the rate was further reduced after injection of SB203580 in Group D compared to Group B (p<0.05). Compared with that in Group C, the expressions of p-p38MAPK and p-ATF-2 in Group D were significantly downregulated after injection of SB203580 (p<0.05). CONCLUSIONS Lower-extremity arterial ischemia-reperfusion postconditioning can significantly reduce the apoptosis level in vascular tissues, decrease the expressions of p-p38MAPK and downstream factor ATF-2, and alleviate the damage in lower-extremity arterial vessels. The inhibition of MAPK pathway further restricted the apoptosis and contributed to a promoting role in the recovery of lower-extremity arterial ischemia-reperfusion injury.

Abstract
To study the expression changes of inflammatory factors heme oxygenase-1 (HO-1), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) in intracerebral hemorrhage (ICH), brain tissues surrounding hematoma were collected from ICH patients. The expressions of HO-1, TNF-α, IL- 1β, and other genes were examined at different time points of ICH. Changes in HO-1, TNF-α, and IL-1β positive cell numbers after ICH were detected by immunohistochemical staining. The results showed that the expressions of HO-1, TNF-α, and IL-1β had no significant changes in brain tissues surrounding hematoma within 6 hours after ICH (P > 0.05). Their expressions during 6-24 hours and 24-72 hours after ICH increased constantly. After reaching the peak, they remained steady or slightly decreased after 72 hours. The dynamic expression changes of HO-1, TNF-α, and IL-1β were observed and their development trends were interfered timely to alleviate the secondary neurological impairment after ICH, which was significant to prevent ICH.

Abstract
From August 1(st) to 7(th), 2017, the breastfeeding knowledge of medical staff were collected from 52 medical health institutions in 29 provinces through a network system. A total of 35 243 questionnaires were included in the study to analyze the current status of breastfeeding knowledge and related factors. The qualified rate of breastfeeding knowledge questionnaires for medical staff in this study was 75.3% (26 546/35 243). Compared with those in the eastern region and those who were mothers, the qualified rate of breastfeeding knowledge of medical staff in the central region or the western region and medical staff who were fathers or expectant parents was lower, with OR (95%CI) values about 0.71 (0.67-0.75), 0.66 (0.61-0.72), 0.63 (0.55-0.72) and 0.87 (0.80-0.95), respectively. Compared with those attaining high school education or below and those with children aged<1 month, the qualified rate of breastfeeding knowledge was higher in medical staff with bachelor's degree, graduate degree or above, and with children aged 1-5, 6-23 and ≥24 months, with OR (95%CI) values about 1.92 (1.80-2.05), 2.16 (1.94-2.42), 2.28 (1.93-2.70), 2.41 (2.06-2.83) and 1.99 (1.72-2.32), respectively.

Abstract
Objective: To understand the early infant diagnosis (EID) test rate and associated factors in HIV-exposed children in China during 2015-2017. Methods: The follow-up information cards of 12 096 HIV-exposed children for 18 months after birth during 2015-2017 were collected from the Management Information System of China's Prevention of Mother-to-Child Transmission of HIV for a retrospective analysis. The EID test characteristics of HIV exposed children and associated factors were analyzed. Results: From 2015 to 2017, the EID test rate in HIV exposed children increased from 65.6% to 83.4% in China (trend χ(2) P<0.001). The EID test rate within 8 weeks after birth increased from 61.1% to 76.8% (trend χ(2) P<0.001), but the EID positive rate decreased from 8.7% to 3.4% (trend χ(2) P<0.001). The EID positive rate in fatal HIV-exposed children was 47.7%, 36.9% and 36.3% during 2015-2017, respectively, the differences were not significant. EID test rate was associated with ethnic group, living area, survival status and the year reaching 18-month-old of the children. Conclusions: The performance of EID test has been standardized step by step in China. The positive rate of EID test decreased gradually with year. However, the EID test rates in children who were from minority ethnic groups, lived in areas with lower prevalence of HIV infection and died within 18 months after birth were relatively low.

Abstract
The precise measurement of the spectrum of protons, the most abundant component of the cosmic radiation, is necessary to understand the source and acceleration of cosmic rays in the Milky Way. This work reports the measurement of the cosmic ray proton fluxes with kinetic energies from 40 GeV to 100 TeV, with 2 1/2 years of data recorded by the DArk Matter Particle Explorer (DAMPE). This is the first time that an experiment directly measures the cosmic ray protons up to ~100 TeV with high statistics. The measured spectrum confirms the spectral hardening at ~300 GeV found by previous experiments and reveals a softening at ~13.6 TeV, with the spectral index changing from ~2.60 to ~2.85. Our result suggests the existence of a new spectral feature of cosmic rays at energies lower than the so-called knee and sheds new light on the origin of Galactic cosmic rays.

Abstract
BACKGROUND Vascular network formation induced by angiogenesis plays an important role in many physiological and pathological processes. However, the role of blood flow and underlying mechanisms in vascular network formation, for example for the development of the caudal vein plexus (CVP), is poorly understood. OBJECTIVE The aim of this study was to explore the role of ERK5-klf2a-nos2b signaling in the CVP angiogenesis. METHOD AND RESULTS In this study on tnnt2a-MO injection and chemical blood flow modulator treatment in zebrafish embryos, we demonstrated that decreased blood flow disrupted CVP formation. The hemodynamic force was quantitatively analyzed. Furthermore, CVP angiogenesis in zebrafish embryos was inhibited by disruption of the blood flow downstream effectors ERK5, klf2a, and nos2b in response to treatment with the ERK5 specific inhibitor and to injection of klf2a-MO, nos2b-MO. Overexpression of klf2a mRNA or nos2b mRNA restored vascular defects in tnnt2a or klf2a morphants. The data suggest that flow-induced ERK5-klf2a-nos2b signaling is involved in CVP angiogenesis in zebrafish embryos. CONCLUSION We have demonstrated that blood flow is essential for vascular network formation, specifically for CVP angiogenesis in zebrafish. A novel genetic and mechanical mechanism was discovered in which ERK5 facilitates the integration of blood flow with the downstream klf2a-nos2b signaling for CVP angiogenesis.

Abstract
Abstract Objective To study the time-dependent expression and distribution of acetylcholinesterase (AChE) during skin incised wound healing in mice, and discuss its effect in wound healing as well as the feasibility of using it as a reference index for wound age estimation. Methods A total of 45 C57BL/KsJ mice were randomly divided into one control group and eight incised groups. The skin incised wound model was established in the incised groups with samples of skin wounds taken at 6 h, 12 h, 1 d, 3 d, 5 d, 7 d, 10 d and 14 d post-injury respectively, while the uninjured skin tissue was extracted in the control group. Expression and distribution of AChE in skin samples were detected by immunohistochemistry, double immunofluorescence and Western blotting. Results Immunohistochemistry results indicated that AChE was mainly detected in infiltrating polymorphonuclear cells (PMNs) 6 to 12 h post-injury. A large number of AChE-positive mononuclear cells (MNCs) were observed 1 to 3 d post-injury. The AChE-positive cells were mainly fibroblastic cells (FBCs) 5 to 14 d post-injury. The ratio of the AChE-positive cells increased initially 6 h post-injury, and reached the peak at 1 d post-injury. Double immunofluorescent staining showed that the majority of AChE-positive MNCs and FBCs expressed macrophage marker and myofibroblast marker, respectively. Western blotting results showed that the relative expression level of AChE in the incised group was higher than that in the control group averagely, reached the peak at 1 d post-injury, then reached a second peak at 7 d post-injury. Conclusion The expression of AChE is found in PMNs, macrophages and myofibroblast during skin wound healing, which indicates it might be involved in the adjustment of inflammatory response and fibrotic repair after injury. Moreover, combined use of various methods for the detection of the expression of AChE would provide reference for skin wound age estimation.

Abstract
We report simple and compact all-fiber erbium-doped soliton and dispersion-managed soliton femtosecond lasers mode-locked by the MXene Ti3C2Tx. A saturable absorber device fabricated by optical deposition of Ti3C2Tx onto a microfiber exhibits strong saturable absorption properties, with a modulation depth of 11.3%. The oscillator operating in the soliton regime produces 597.8 fs-pulses with 5.21 nm of bandwidth, while the cavity with weak normal dispersion (~0.008 ps2) delivers 104 fs pulses with 42.5 nm of bandwidth. Our results contribute to the growing body of work studying the nonlinear optical properties of MXene that underpin new opportunities for ultrafast photonic technology.

Abstract
Immunological methods, which have been widely used in autoimmune blistering diseases (AIBDs) of the oral mucosa, can also be adopted as auxiliary diagnostic tools in oral lichen planus (OLP) and discoid lupus erythematosus (DLE). AIBDs, characterized by autoantibodies against structural proteins of keratinocytes or the basement membrane zone, clinically present as blisters and erosions of the oral mucosa. When atypical lesions occur, OLP or DLE may be confused with AIBDs. The improvement of diagnostic accuracy is necessary due to the significant differences in treatment and prognosis among these diseases. A variety of immunological methods are used for qualitative and quantitative detection of target antigens and autoantibodies. These methods can evaluate efficacy of treatment, monitor diseases and guide treatment decisions. In this review, we discuss the application of immunofluorescence, biochemical tests, and protein microarrays for AIBDs, OLP and DLE, as well as the differential diagnostic methods using immunological tests.

Abstract
OBJECTIVES To investigate the expression changes of annexin A1 (ANXA1) during the process of skin incision healing, and to explore its expression and function during skin injury repair. METHODS The skin injury model of mice was prepared, and skin tissues of the controls and the injured group at 6 h, 12 h, 1 d, 3 d, 5 d, 7 d, 10 d and 14 d after injuries were taken. The morphological changes of the wound were observed by hematoxylin-eosin (HE) staining, and the expression of ANXA1 was detected by immunohistochemistry (IHC) and Western blotting. RESULTS HE staining showed normal healing of skin wounds. IHC results revealed that ANXA1 was expressed in the epidermis, hair follicle, sebaceous gland and vascular endothelium. In the injured group, the expression of ANXA1 was enhanced in epidermis and skin appendages around the wound 6-12 h after injury, and ANXA1 was also highly expressed in neutrophils and a small number of mononuclear cells. ANXA1 was mainly positively expressed in monocytes, neovascular endothelial cells and fibroblasts, and small amount of fibroblasts at 1-3 d, 5-10 d, and 14 d after injury, respectively. Western blotting showed that, compared with the controls, the expression of ANXA1 was significantly increased at 6 h after injury, peaked at 1 d, and then decreased gradually in the injured group. CONCLUSIONS ANXA1 may be involved in the regulation of skin damage repair, with time-dependent expression during skin wound healing, and thus is expected to be a biological marker for inferring the wound formation time.

Abstract
Aim
This study aimed to develop a nomogram based on clinicopathological features to evaluate the recurrence probability of breast phyllodes tumors following surgery. The criteria for atypia, mitoses, overgrowth, and surgical margin (AMOS) were also validated.
Method
Data from 334 patients with breast phyllodes tumors, who underwent surgical treatment at Sun Yat-sen Memorial Hospital from January 2005 to December 2014, were used to develop a prediction model. Additionally, data of 36 patients from Peking University Shenzhen Hospital and data of 140 patients from Sun Yat-sen University Cancer Center during the same period were used to validate the model. The medical records and tumor slides were retrospectively reviewed. The log-rank and Cox regression tests were used to develop a clinical prediction model of breast phyllodes tumors as well as validating the AMOS criteriaAll statistical analyses were performed using R and STATA.
Results
Of all 334 patients included in the study, 224 had benign, 91 had borderline, and 19 had malignant tumors. The local and distant recurrence rate was 17.7%. The 1-,3-, and 5-year cumulative recurrence-free survival was 98.5%, 97.9%, and 96.8%, respectively. Surgical margin, mitoses, and tumor border were identified as independent risk factors for breast phyllodes tumors. A nomogram was developed based on these three variables. The C-index of internal and external validation was 0.71and 0.67, respectively. The area under the curve of AMOS criteria was 0.59.
Conclusions
The present study model presented a more concise and objective variables to evaluate the recurrence-free survival of patients after surgery compared with that using the AMOS criteria, which is more appropriate for clinical practice and also allows for a more accurate prediction.

Abstract
Abstract
Purpose:
Chemotherapy remains the only systemic treatment option for patients with triple-negative breast cancer (TNBC). However, due to the heterogeneity of TNBC, not all patients benefit from chemotherapy, especially those with early-stage disease. In order to improve prognostic assessment and reduce unnecessary adjuvant systemic therapy in these patients, we have developed a novel seven-gene signature.
Experimental Design:
With the ComBat method, we integrated the results from 150 transcriptome microarrays samples and 246 RNA-seq samples of early-stage TNBC patients, and identified mRNAs associated with recurrence-free survival (RFS) using Lasso-Cox model, We further analyzed these TNBC samples and compared them with 60 paired normal breast tissues (40 samples from RNA-seq and 20 samples from microarrays) to identify tumor-specific mRNAs. Twenty-one overlapped mRNAs of the RFS-associated mRNAs and the tumor-specific mRNAs are selected as candidate mRNAs. An additional 371 samples of frozen primary tumors were then collected from early-stage TNBC patients (mean follow-up of 45 months) and randomly divided into two sets: a training set (n = 186) and a validation (n = 185) set. Expression level of candidate mRNAs in these samples were measured using RT-qPCR assays, and a seven-gene signature was built through all subset regression in the training set. The prognostic and predictive accuracy of our signature was tested in the validation set and other public databases (GSE5327, GSE2034 and METABRIC).
Results:
Twenty-one candidate mRNAs were identified in early-stage TNBC patients, from which we developed a novel seven-gene signature (recurrence risk score [mRNA signature] = 1.108*TMEM101 - 0.213*KRT5 - 0.315*ACAN - 0.464*LCA5 + 0.446*RPP40 - 0.373*LAGE3 - 0.257*CDKL2). Patients in the training set were classified into high- or low-risk group based on our seven-gene signature and an optimum cut-off score derived from x-tile. The patients in high-risk group were more likely to suffer from recurrence (HR, 2.718; 95% confidence interval [CI], 1.928–3.726, P= 0.001), and a time-dependent receiver operating curve showed that the seven-gene mRNA signature had a better prognostic value than the clinicopathologic risk factors in both training set and validation set. The prognostic and predictive accuracy of the signature was also validated in the METABRIC and two other public GEO databases (GSE5327 and GSE2034). The time-dependent receiver operating curve showed that this signature had an area under the curve (AUC) of 0.742 (95% CI, 0.705-0.773) in METABRIC, 0.716 (95% CI, 0.682-0.739) and 0.723 (95% CI, 0.683-0.756) in GSE5327 and GSE2034 respectively.
Conclusion:
In this study, we developed a novel seven-gene signature which can provide additional prognostic information and may guidance in identifying early-stage TNBC patients eligible for adjuvant therapy or reduction of chemotherapy. To our knowledge, this is the first study investigating the prognostic potential of mRNA signature in early-stage triple-negative breast cancer. Our novel signature may provide an opportunity for de-escalating treatment in early-stage TNBC patients in the future.

Abstract
Abstract
Background Triple positive breast cancers (TPBCs), i.e. estrogen receptor-positive (ER+)/ progesterone receptor-positive (PR+)/ human epidermal growth factor receptor 2-positive (HER2+) breast cancers, constitute a therapeutic challenge due to the functional crosstalk between the hormone receptors and HER2 pathways. The intrinsic molecular subtyping of TPBCs has rarely been studied and may have implications for the prognostic evaluation and therapeutic decision-making.
Methods Our study included four cohorts of patients with TPBC. The first one consisted of 82 patients from The Cancer Genome Atlas (TCGA). The second and third ones were from two publicly available microarray datasets (GSE2603 and GSE2109) and included 37 and 30 patients respectively. The forth one comprised 165 patients from Fudan University Shanghai Cancer Center. First, we examined the PAM50 intrinsic subtypes of TPBCs in the first three cohorts. Then, we tried to find several differentially expressed genes (DEGs) between luminal A and the other subtypes. In cohort 1, we identified DEGs using LIMMA. In cohort 2 and 3, we further filtered and validated them using Wilcoxon's rank sum test. We also performed Receiver operating characteristic analyses to evaluate the accuracy of candidate DEGs in identifying TPBCs of luminal A subtype and determined the top 3 DEGs according to the area under the curve. Finally, in cohort 4, we detected the expression of these 3 genes by immunohistochemical (IHC) staining of tissue sections, defined a group of luminal A-like TPBCs and examined the prognosis and effect of adjuvant trastuzumab for them.
Results The distribution of PAM50 intrinsic subtypes of TPBCs was shown as follows. The three genes that exhibited the highest accuracy in identifying TPBCs of luminal A subtype were STC2, BCL2 (highly expressed in luminal A subtype) and MKI67 (lowly expressed in luminal A subtype). In cohort 4, we defined a group of luminal A-like TPBCs as TPBCs with low expression of MKI67 as well as high expression of STC2 and/or BCL2. Compared with patients with non-luminal A-like TPBC (n = 110), those with luminal A-like TPBC (n = 55) had better disease-free survival (DFS) in both univariate (Log-rank P = 0.029) and multivariate analyses (hazard ratio = 0.25, P = 0.025). In the group with non-luminal A-like TPBCs, patients treated with trastuzumab (n = 67) showed better DFS than those not treated with it (n = 43) (Log-rank P = 0.019), while in the group with luminal A-like TPBCs, there is no difference in DFS between patients treated with trastuzumab (n = 22) and those not treated with it (n = 33) (Log-rank P = 0.993).

Conclusions TPBCs are heterogeneous in terms of intrinsic molecular subtype. Evaluating the expression of STC2, BCL2 and MKI67 by IHC staining can help us to conveniently identify a group of luminal A-like TPBCs. Patients with this group of TPBCs have relatively good prognosis and may only gain limited benefit from adjuvant trastuzumab.

Abstract
The history of vascular surgery in new China could be divided into the following three stages: the first stage, since the early 1980s, the technique of endovascular surgery was introduced in China, developed in some major hospitals, and gradually popularized to some basic hospitals conditionally. Vascular surgery had gradually developed into an independent discipline in China by the late 1980s. The second stage, since the late 1980s, vascular diagnosis and treatment technology, vascular equipment, and related research modification had been improving continuously in China, and achieved certain success, especially since the establishment of the department of vascular surgery affiliated to the Chinese Medical Association in 1993, vascular surgery in China representing its period of primary development. The third stage, since the beginning of the 21st century, the innovation of the technique of endovascular surgery and hybridization technology, and the development of materials technology had contributed to the second leaping forward of vascular surgery in China. Since then, vascular surgery enters a new era of minimally invasive surgery and opens a period of rapid development.

Abstract
The hippocampus is a brain structure that plays a fundamental role in memory and learning. Many animal studies have demonstrated that the structure of the hippocampus has evolved through exercise and play. However, little is known on the relationship between the brain and immunological reaction. In this study, we investigated the correlation between the weight of the hippocampus and transplant immunology in a murine heart transplant model. Fully vascularized heterotopic hearts from CBA (H2k, allogeneic group) or C57BL/6 (H2b, syngeneic group) donors were transplanted into C57BL/6 recipients by using microsurgical techniques. The weights of the whole brain and hippocampus from syngeneic and allogeneic groups were recorded 1, 2, and 4 weeks after grafting, and histologic assessments were performed. The syngeneic group maintained beating cardiac grafts for over 30 days, but the allogeneic group rejected CBA cardiac allografts acutely within 8 days. The average weight of whole brain from syngeneic and allogeneic group 1, 2, and 4 weeks had no significant differences. However, the average weight of hippocampus at 2 and 4 weeks was considerably increased in the allogeneic group compared with the syngeneic group. Histologic assessments with hematoxylin-eosin and Kluver-Barrera staining of hippocampus from allogeneic group 1 week after grafting demonstrated a greater number of granule and pyramidal cells in the hippocampus. Alloimmune responses in our model increase the weight of hippocampus.
