Abstract
Objective: To investigate the effects and mechanism of sympathetic neurotransmitter norepinephrine (NE) on the migration of bone marrow mesenchymal stem cells (BMSCs) in mice. Methods: (1) Twenty 3-week-old male C57BL/6 mice were sacrificed for isolating, culturing, and identifying BMSCs from the femur and tibia. Cells of the second or third passages were divided into phosphate buffer solution (PBS) group, 1 μmol/L NE group, 10 μmol/L NE group, and 100 μmol/L NE group, with 8 wells in each group. Cells in 1 μmol/L NE group, 10 μmol/L NE group, and 100 μmol/L NE group were cultured in low-sugar Dulbecco's modified eagle medium containing 1% volume fraction of fetal bovine serum (hereinafter referred to as low-serum medium) added with NE in final molarity of 1 μmol/L, 10 μmol/L, and 100 μmol/L, respectively. Cells in PBS group were cultured in low-serum medium added with the same volume of PBS. Before stimulation (0 d) and on stimulation day 1, 3, 5, cell counting kit 8 method was used to detect cell proliferation activity (expressed as the absorbance value). (2) In cell scratch test 1, cells were divided into PBS group and simple NE group. After the scratch test, cells in simple NE group were cultured with low-serum medium+ NE in final molarity of 10 μmol/L, and cells in PBS group were cultured with low-serum medium+ the same volume of PBS. In cell scratch test 2, cells were divided into PBS group, propranolol+ NE group, and phentolamine+ NE group. After the scratch test, cells in propranolol+ NE group were pretreated with low-serum medium+ propranolol in final molarity of 1 μmol/L for 30 minutes each day, cells in phentolamine+ NE group were pretreated with low-serum medium+ phentolamine in final molarity of 10 μmol/L for 30 minutes each day, and then they were cultured with low-serum medium+ NE in final molarity of 10 μmol/L. Cells in PBS group were cultured with low-serum medium+ the same volume of PBS. In cell scratch test 3, cells were divided into simple NE group, simple (2E, 6E)-2, 6-bis (4-pyridylmethylene) cyclohexanone (SC-66) group, and SC-66+ NE group. After the scratch test, cells in simple NE group was cultured with low-serum medium+ NE in final molarity of 10 μmol/L, cells in simple SC-66 group were cultured with low-serum medium after being pretreated with SC-66 in final molarity of 30 mmol/L for 30 minutes every day, cells in SC-66+ NE group were cultured with low-serum medium+ NE in final molarity of 10 μmol/L after being pretreated with SC-66 in final molarity of 30 mmol/L for 30 minutes every day. In the above 3 cell scratch tests, the sample numbers in each group were all 6, and the scratch healing rates at post scratch hour (PSH) 24, 48, and 72 were all calculated. (3) Cells were divided into PBS group, simple NE group, propranolol+ NE group, and phentolamine+ NE group, with 3 wells in each group. The lower chamber treatment methods of PBS group and simple NE group were the same as those of the same groups in cell scratch test 1. The lower chamber treatment of propranolol+ NE group and phentolamine+ NE group were the same as those of the same groups in cell scratch test 2. After the Transwell experiment was performed and the cells were routinely cultured for 24 hours, the migrated cells were counted. (4) Cells were divided into PBS group, simple NE group, propranolol+ NE group, and phentolamine+ NE group, with 2 dishes in each group. The cell treatment of PBS group and simple NE group were the same as those of the same groups in cell scratch test 1. The cell treatment of propranolol+ NE group and phentolamine+ NE group were the same as those of the same groups in cell scratch test 2. After 24 hours of routine culture, the phosphorylation level of protein kinase B (Akt) of cells was detected by Western blotting. Data were statistically analyzed with analysis of variance for repeated measurement, one-way analysis of variance, independent sample t test, least significant difference t test, and Bonferroni correction. Results: (1) After 1 day of stimulation, the absorbance value of cells in 100 μmol/L NE group was significantly lower than that in PBS group (t=2.986, P<0.05). After 5 days of stimulation, the absorbance value of cells in 10 μmol/L NE group was significantly higher than that in PBS group (t=3.547, P<0.01). (2) In cell scratch test 1, at PSH 24, 48, and 72, the scratch healing rates of cells in simple NE group were (34.4±3.4)%, (52.5±4.7)%, and (70.0±3.8)%, which were significantly lower than (44.1±4.2)%, (80.0±3.6)%, and (95.9±2.2)% in PBS group (t=19.320, 128.319, 221.575, P<0.01). In cell scratch test 2, at PSH 24, 48, and 72, the scratch healing rates of cells in propranolol+ NE group were significantly lower than those in PBS group (t=4.073, 9.618, 15.272, P<0.01). In cell scratch test 3, at PSH 72, the scratch healing rates of cells in NE group was significantly lower than that in simple SC-66 group (t=8.862, P<0.01). At PSH 24, 48, and 72, the scratch healing rates of cells in SC-66+ NE group were significantly lower than those in simple SC-66 group (t=3.862, 4.290, 10.357, P<0.01). (3) The Transwell experiment showed that after 24 hours of culture, the numbers of migrated cells in simple NE group, propranolol+ NE group, and phentolamine+ NE group were significantly less than the number in PBS group (t=11.895, 10.196, 3.222, P<0.01). (4) After 24 hours of culture, the phosphorylation levels of Akt of cells in simple NE group and propranolol+ NE group were significantly higher than the level in PBS group (t=8.186, 5.996, P<0.01). Conclusions: NE can inhibit the migration of BMSCs in mice, a process in which the signal pathway of Akt is involved in its regulation.

Abstract
Background Annually > 10% of patients with atrial fibrillation on oral anticoagulation undergo invasive procedures. Optimal peri-procedural management of anticoagulation, as judged by major bleeding and thromboembolic events, especially in the elderly, is still debated. Methods Procedures from 1442 patients were evaluated. Peri-procedural edoxaban management was guided only by the experience of the attending physician. The primary safety outcome was the rate of major bleeding. Secondary outcomes included the peri-procedural administration of edoxaban, other bleeding events, and the main efficacy outcome, a composite of acute coronary syndrome, non-hemorrhagic stroke, transient ischemic attack, systemic embolic events, deep vein thrombosis, pulmonary embolism, and mortality. Results Of the 1442 patients, 280 (19%) were < 65, 550 (38%) were 65–74, 514 (36%) 75–84, and 98 (7%) were 85 years old or older. With increasing age, comorbidities and risk scores were higher. Any bleeding complications were uncommon across all ages, ranging from 3.9% in patients < 65 to 4.1% in those 85 years or older; major bleeding rates in any age group were ≤ 0.6%. Interruption rates and duration increased with advancing age. Thromboembolic events were more common in the elderly, with all nine events occurring in those > 65, and seven in patients aged > 75 years. Conclusion Despite increased bleeding risk factors in the elderly, bleeding rates were small and similar across all age groups. However, there was a trend toward more thromboembolic complications with advancing age. Further efforts to identify the optimal management to reduce ischemic complications are needed.

Abstract
AIM Haemorrhoidal disease can severely affect a patient's quality of life. Its classification is commonly based on morphology of the degree of prolapse; however, this does not take into account the symptoms and impact on the quality of life. The aim of this systematic review was to determine the most appropriate instruments that classify the severity of disease according to symptoms. METHOD A PRISMA-compliant search was conducted in December 2019 to identify studies that described the validation of a haemorrhoidal symptom score. The measurement properties of the scoring systems were assessed based on the consensus-based standards for the selection of health status measurement instruments (COSMIN) methodology for systematic reviews for patient-reported outcome measures. RESULTS A total of 5288 articles were identified, with five articles included. Three studies developed a scoring system based on a set of core symptoms for a cohort of patients and validated the score against treatment outcomes. One study developed a disease-specific quality of life questionnaire based on symptoms to evaluate disease burden. One study combined both quality of life and symptom measures and tested measurement properties on two cohorts of patients. Only one study demonstrated satisfactory valid, reliable and responsive measurement criteria. CONCLUSION A single study demonstrated sufficient quality in measurement properties to be recommended for clinical use. Further studies in this area should utilize consensus-based standards for designing and reporting validation research to ensure that the appropriate evidence base is acquired if any further patient-reported outcome measures are to be recommended.

Abstract
Objective: To identify the risk factors of non-sentinel lymph node (nSLN) metastasis in breast cancer patients with 1~2 positive axillary sentinel lymph node (SLN) and construct an accurate prediction model. Methods: Retrospective chart review was performed in 917 breast cancer patients who underwent surgery treatment between 2002 and 2017 and pathologically confirmed 1-2 positive SLNs. According to the date of surgery, patients were divided into training group (497 cases) and validation group (420 cases). A nomogram was built to predict nSLN metastasis and the accuracy of the model was validated. Results: Among the 917 patients, 251 (27.4%) had nSLN metastasis. Univariate analysis showed tumor grade, lymphovascular invasion (LVI), extra-capsular extension (ECE), the number of positive and negative SLN and macro-metastasis of SLN were associated with nSLN metastasis (all P<0.05). Multivariate Logistic regression analysis showed the numbers of positive SLN, negative SLN and macro-metastasis of SLN were independent predictors of nSLN metastasis (all P<0.05). A nomogram was constructed based on the 6 factors. The area under the receiver operating characteristic curve was 0.718 for the training group and 0.742 for the validation group. Conclusion: We have developed a nomogram that uses 6 risk factors commonly available to accurately estimate the likelihood of nSLN metastasis for individual patient, which might be helpful for radiation oncologists to make a decision on regional nodal irradiation.

Abstract
Objective: To explore the correlation between preoperative serum hyaluronic acid (HA) level and prognosis of breast cancer patients. Methods: The 98 patients with breast cancer who underwent surgical treatment in the Oncology Department of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from January 2004 to November 2014 in a historical cohort were included, aged (52.5±9.4) years.The preoperative serum HA contents of the patients were detected. According to the median of 53.7 μg/L, the patients were divided into high and low groups with 49 patients in each group.The χ2 test was used to analyze the correlation between the serum HA content and the general clinical data of the patients, and the Kaplan-Meier method, Log-rank test and multivariate Cox regression model wereusedto analyze the correlation between HA content and patients' survival. Results: The percentages of patients with high HA levels in menopause and non-menopause patientswere 55.7% and 40.5%, respectively; in progesterone receptor (PR) positive and negative patients were 54.1% and 43.2%, respectively; in estrogen receptor (ER) positive and negative patients were 45.7% and 60.7%, respectively; in Ki-67 positive and negative patients were 55.6% and 43.2%, respectively; in the tumor size stage TⅠ, TⅡ, TⅢ, and TⅣ patients were 50.0%, 41.7%, 72.7%, and 1/1, respectively; in lymph node metastasis and non-metastasispatients were 45.7% and 53.8%, respectively. There was no significant correlation between the level of HA and the menopausal status, the expressions of PR, ER and Ki-67, tumor size, and lymph node metastasis in breast cancer patients (χ²=2.128, 1.086, 1.800, 1.485, 4.273, 0.656, P>0.05). Patients with high HA levels accounted for 30.9% of patients aged 52 years or less and 74.4% of patients older than 52 years (χ²=18.274, P=0.000); 43.4% of patients with early TNM and 72.7% of patients with advanced TNM (χ²=5.861, P=0.015); 45.2% of patients without distant metastasis and 78.6% of patients with distant metastasis (χ²=5.333, P=0.023); 38.1% of Her-2 negative patients and 58.9% of Her-2 positive patients(χ²=4.167, P=0.041); and the median survival of patients with high HA levels was 70 months, which was shorter than 83 months for patients with low HA levels (χ²=6.799, P=0.007). Therefore, ahigh HA content predicts an older age, a later tumor stage, higher risk of distant metastasis, positive expression of Her-2 and shorter survival. Multivariate Cox regression model analysis suggested that high levels of serum HA may be a risk factor for patients' survival, with HR (95%CI) value of 9.98 (1.16-85.88) and P value of 0.036. Conclusion: The high level of preoperative serum HA has a certain correlation with the poor prognosis of breast cancer patients.

Abstract
OBJECTIVE S100 proteins conduce to tumorigenesis and metastasis in a variety of ways, facilitating a local inflammatory environment for development and progression of tumors. However, the expression patterns and the precise roles of the S100 family members contributing to tumorigenesis and the progression of acute myeloid leukemia (AML) remain to be elucidated. MATERIALS AND METHODS Herein, the expression of S100 transcripts was analyzed in various tumor types in comparison to the normal controls using the ONCOMINE database, along with the corresponding expression profiles in the different subtypes of AML as retrieved from The Cancer Genome Atlas (TCGA) database. We used the Gene Expression Profiling Interactive Analysis (GEPIA) database to investigate the prognostic values of S100 mRNA expression in AML. RESULTS Our results indicated that high expression of S100A4 mRNA was associated with poor overall survival (OS) (p=0.026), while that of S100P was correlated with a favorable OS in AML patients (p=0.028). Other members of the S100 family did not show any correlation to the survival. Moreover, the correlation between the expression levels of S100A4 and S100P and the clinical characteristics and methylation of AML patients was investigated. The results demonstrated that the promoter methylation level of S100A4 (p=0.002) and S100P (p=0.029) was higher in 61-80-years-old group as compared to the other age groups. CONCLUSIONS Taken together, it can be deduced that S100A4 and S100P might be novel biomarkers and crucial prognostic factors for AML.

Abstract
Objective: To evaluate the incidence of early cardiac injury in patients with left-sided breast cancer receiving hypofractionated radiotherapy after breast conserving surgery, and to investigate the correlation between cardiac injury and hypofractionated radiotherapy dose. Methods: We prospectively enrolled 103 breast cancer patients who received whole breast with or without regional nodal irradiation after breast conserving surgery using either deep inspiration breath-hold (DIBH) or free breathing (FB) radiotherapy technique. Cardiac examinations that included N-terminal pro-B-type natriuretic peptide (NT-proBNP), electrocardiogram, and myocardial perfusion imaging were performed routinely before and after radiotherapy. The effects of heart dose, systemic therapy and individual factors (Framingham score) on the incidence of cardiac events were analyzed. Results: The median age was 48 years. The mean dose (Dmean) of the heart, left anterior descending coronary artery (LAD), left ventricular (LV), and right ventricular (RV) were 4.0, 16.9, 6.3, and 4.4 Gy, respectively. With a median follow-up of 13.4 months, no patient had clinical cardiac abnormalities. The incidence rates of subclinical cardiac events at 1- 6- and 12-month were 23.5%, 31.6%, and 41.3%, respectively. The DIBH group had a lower mean dose, maximum dose, and V5-V40 in the heart, LAD, LV, and RV than the FB group (P<0.001). Univariate analysis showed an increased incidence of subclinical cardiac events with heart Dmean >4 Gy, LAD V40 > 20%, LV Dmean >6 Gy, RV Dmean >7 Gy, or cumulative doses of anthracycline or taxane > 300 mg/m(2) (All P<0.05). Anti-HER2 targeted therapy, endocrine therapy and Framingham score were not associated with the incidence of subclinical cardiac events (all P>0.05). Multivariate analysis demonstrated that Dmean of LV and RV were independently associated with the increased incidence of subclinical cardiac events. Conclusions: Early subclinical heart injury are found in patients with left-sided breast cancer after hypofractionated radiotherapy. The increased incidence of subclinical cardiac events after radiotherapy is positively associated with the cardiac radiation doses.

Abstract
Alginate-degrading bacteria or alginate lyases can be used to oligomerize alginate. In this study, an alginate-degrading bacterium with high alginolytic activity was successfully screened by using Sargassum fusiforme sludge. When the strain was grown on a plate containing sodium alginate, the transparent ring diameter (D) was 2.2 cm and the ratio (D/d) of transparent ring diameter to colony diameter (d) was 8.8. After 36 h in culture at a temperature of 28 °C shaken at 150 r/min, the enzymatic activity of the fermentation supernatant reached 160 U/mL, and the enzymatic activity of the bacterial precipitate harvested was 2,645 U/mL. The strain was named Cobetia sp. cqz5-12. Its genome is circular in shape, 4,209,007 bp in size, with a 62.36% GC content. It contains 3,498 predicted coding genes, 72 tRNA genes, and 21 rRNA genes. The functional annotations for the coding genes demonstrated that there were 181 coding genes in the genome related to carbohydrate transport and metabolism and 699 coding genes with unknown functions. Three putative coding genes, alg2107, alg2108 and alg2112, related to alginate degradation were identified by analyzing the carbohydrate active enzyme (CAZy) database. Moreover, proteins Alg2107 and Alg2112 were successfully expressed and exhibited alginate lyase activity.

Abstract
Background In this research, we used the mediastinal lymph node reclassification proposed by the International Association for the Study of Lung Cancer (iaslc) to screen for patients with pathologic N2 (pN2) non-small-cell lung cancer (nsclc) who might benefit from postoperative radiotherapy (port). Methods The study enrolled 440 patients with pN2 nsclc who received complete surgical resection and allocated them to one of three groups: N2a1 (single-station skip mediastinal lymph node metastasis), N2a2 (single-station non-skip mediastinal lymph node metastasis), and N2b (multi-station mediastinal lymph node metastasis). Rates of local recurrence at first recurrence in patients receiving and not receiving port were compared using the chi-square test. Overall (os) and disease-free survival (dfs) were then compared using Kaplan-Meier survival analysis with log-rank test. In addition, the factors potentially influencing os and dfs were analyzed using univariate and multivariate Cox regression. Results The rate of local recurrence for the N2a2 and N2b groups was significantly lower in patients receiving port (p = 0.044 and p = 0.043 respectively). The log-rank test revealed that, for the N2a1 group, differences in os and dfs were not statistically significant between the patients who did and did not receive port (p = 0.304 and p = 0.197 respectively). For the N2a2 group, os and dfs were markedly superior in patients who received port compared with those who did not (p = 0.001 and p = 0.014 respectively). For the N2b group, os was evidently better in patients who received port compared with those who did not (p = 0.025), but no statistically significant difference in dfs was observed (p = 0.134). Multivariate regression analysis revealed that, in the N2a1 group, port was significantly associated with poor os [hazard ratio (hr): 2.618; 95% confidence interval (ci): 1.185 to 5.785; p = 0.017]; in the N2a2 group, port was associated with improved os (hr: 0.481; 95% ci: 0.314 to 0.736; p = 0.001) and dfs (hr: 0.685; 95% ci: 0.479 to 0.980; p = 0.039). Conclusions For patients with pN2 nsclc who receive complete resection, port might be beneficial only for patients with single-station non-skip metastasis (N2a2). Patients with single-station skip metastasis (N2a1) and multi-station metastasis (N2b) might not currently benefit from port.

Abstract
Objective: To investigate the risk factors of prolonged postoperative length of stay (LOS) in patients with gastric cancer. Methods: A retrospective study was performed on 2033 patients who underwent curative surgery in Department of Pancreatic-gastric, Cancer Hospital, Chinese Academy of Medical Sciences. Eightieth percentile of postoperative hospital stay for all patients was taken as the cutoff, the patients were divided into the normal group (1 532 patients) and the extended group (501 patients). Logistic regression model was used to determine the risk factors related to prolonged postoperative LOS in gastric cancer. Results: A total of 417 cases with postoperative complications were recruited in extended group. The five highest complications accounting for prolonged LOS were: abdominal infection in 69 cases (13.77%), pleural effusion in 60 cases (11.98%), anastomotic leakage in 43 cases (8.58%), poor wound healing in 34 cases (6.79%), and bleeding in 25 cases (4.99%). Logistic regression analysis showed that age (OR=1.348, P=0.013), surgical procedure (OR=2.712, P<0.001), extent of resection (OR=2.035, P<0.001), degree of incision healing(OR=4.867, P<0.001), and perioperative blood transfusion (OR=1.711, P<0.001) were independent risk factors for prolonged postoperative LOS. Conclusions: The most common complication associated with prolonged postoperative LOS for gastric cancer patients is abdominal infection. Age, surgical procedure, extent of resection, degree of incision healing, and perioperative blood transfusion are the independent risk factors for prolonged postoperative LOS.

Abstract
Many arthropod venom peptides have potential as bioinsecticides, drug leads, and pharmacological tools due to their specific neuromodulatory functions. Assassin flies (Asilidae) are a family of predaceous dipterans that produce a unique and complex peptide-rich venom for killing insect prey and deterring predators. However, very little is known about the structure and function of their venom peptides. We therefore used an E. coli periplasmic expression system to express four disulfide-rich peptides that we previously reported to exist in venom of the giant assassin fly Dolopus genitalis. After purification, each recombinant peptide eluted from a C18 column at a position closely matching its natural counterpart, strongly suggesting adoption of the native tertiary fold. Injection of purified recombinant peptides into blowflies (Lucilia cuprina) and crickets (Acheta domestica) revealed that two of the four recombinant peptides, named rDg3b and rDg12, inhibited escape behaviour in a manner that was rapid in onset (<1 min) and reversible. Homonuclear NMR solution structures revealed that rDg3b and rDg12 adopt cystine-stabilised α/ß defensin and inhibitor cystine knot folds, respectively. Although the closest known homologues of rDg3b at the level of primary structure are dipteran antimicrobial peptides such as sapecin and lucifensin, a DALI search showed that the tertiary structure of rDg3b most closely resembles the KV11.1-specific α-potassium channel toxin CnErg1 from venom of the scorpion Centruroides noxius. This is mainly due to the deletion of a large, unstructured loop between the first and second cysteine residues present in Dg3b homologues from non-asiloid, but not existing in asiloid, species. Patch-clamp electrophysiology experiments revealed that rDg3b shifts the voltage-dependence of KV11.1 channel activation to more depolarised potentials, but has no effect on KV1.3, KV2.1, KV10.1, KCa1.1, or the Drosophila Shaker channel. Although rDg12 shares the inhibitor cystine knot structure of many gating modifier toxins, rDg12 did not affect any of these KV channel subtypes. Our results demonstrate that multiple disulfide-rich peptide scaffolds have been convergently recruited into asilid and other animal venoms, and they provide insight into the molecular evolution accompanying their weaponisation.

Abstract
In this study, to investigate the effect of overexpression of miR-146a on autophagy of hippocampal neurons in rats with intracerebral hemorrhage (ICH), 72 Sprague-Dawley rats were randomly divided into the sham, ICH, miR-146a agomir, and miR-146a agomir control groups. The ICH model was constructed by injection of collagenase VII. The apoptosis of hippocampal neurons was measured by TUNEL assay. The levels of LC3 and Beclin 1 were analyzed by immunohistochemistry. Mitochondrial autophagy was examined by transmission electron microscopy. The levels of LC3A, LC3B, Beclin 1, Bax, Bcl-2, and cleaved caspase 3 were examined by Western blot. Western blot was also used to evaluate the expression of nuclear factor κB signaling pathway-related factors. To examine the effect of autophagy inhibitor (3-methyladenine (3-MA)) on miR-146a-regulated apoptotic protein expression, 30 rats were further divided into the sham, ICH, miR-146a agomir, 3-MA, and miR-146a + 3-MA groups. The levels of Bax, Bcl-2, and cleaved caspase 3 were examined by Western blot. Compared with the sham group, the nerve function scores, brain water content, the percentage of apoptotic cells, and the expression levels of LC3, Beclin 1, Bax, cleaved caspase 3, and p-P65 in the hippocampus of rats in the ICH group were all significantly increased (p < 0.05), whereas the expression levels of miR-146a, Bcl-2, and p-IκBα were markedly decreased (p < 0.05). Mitochondrial autophagy was also evident. Furthermore, compared with the ICH group, the results of the abovementioned tests in the miR-146a agomir group were reversed. The overexpression of miR-146a inhibited the autophagy of hippocampal neurons in rats with ICH.

Abstract
Assassin bugs (Reduviidae) produce venoms that are insecticidal, and which induce pain in predators, but the composition and function of their individual venom components is poorly understood. We report findings on the venom system of the red-spotted assassin bug Platymeris rhadamanthus, a large species of African origin that is unique in propelling venom as a projectile weapon when threatened. We performed RNA sequencing experiments on venom glands (separate transcriptomes of the posterior main gland, PMG, and the anterior main gland, AMG), and proteomic experiments on venom that was either defensively propelled or collected from the proboscis in response to electrostimulation. We resolved a venom proteome comprising 166 polypeptides. Both defensively propelled venom and most venom samples collected in response to electrostimulation show a protein profile similar to the predicted secretory products of the PMG, with a smaller contribution from the AMG. Pooled venom samples induce calcium influx via membrane lysis when applied to mammalian neuronal cells, consistent with their ability to cause pain when propelled into the eyes or mucus membranes of potential predators. The same venom induces rapid paralysis and death when injected into fruit flies. These data suggest that the cytolytic, insecticidal venom used by reduviids to capture prey is also a highly effective defensive weapon when propelled at predators.

Abstract
BACKGROUND The metabolic activity of retina is higher than other human tissues and is crucial to the vision. Cynomolgus macaques is widely used in ophthalmic disease research. The evaluation and comparison of macular and optic disc vascular circulation parameters between normal adult cynomolgus macaques and healthy adult humans using OCT-A can promote better use of nonhuman primate models in studies of ophthalmic vascular disease. METHODS Twelve normal adult cynomolgus macaques with a mean age of 4.91 ± 0.43 years were studied for data collection. The macula of 28 adult healthy humans (14 males and 14 females), with a mean age of 25.11 ± 6.21 years and the optic discs of 9 adult healthy humans (4 males and 5 females) with a mean age of 28.56 ± 6.78 years were measured. The vessel density (VD) was measured using an RTVue XR with AngioVue. The scan sizes of the macular and optic discs were 3 × 3 mm and 4.5 × 4.5 mm, respectively. RESULTS OCT-A can image the superficial and deep capillary plexuses and radial peripapillary capillary network. In RPC layer of the optic disc, the VD in the nasal quadrant was lower than the VD in the inferior temporal quadrant. Similarities and significant differences in VD between healthy humans and cynomolgus macaques were obtained using OCT-A. CONCLUSIONS This study provides normal vascular parameters for adult cynomolgus macaques using OCT-A to help establish an optical parameter database for cynomolgus macaques and compare VD between healthy humans and cynomolgus macaques to promote choroid-retinopathy research.

Abstract
Objective: To validate whether the prognostic stage groups by the 8th edition of the American Joint Committee on Cancer (AJCC) staging system provides improved prognostic accuracy in T1-2N1M0 postmastectomy breast cancer patients compared to 7th edition. Methods: a total of 1 823 female patients with T1-2N1M0 breast cancer who underwent mastectomy and axillary lymph node dissection without neoadjuvant chemotherapy were analyzed and restaged according to 8th edition. Univariate analysis of prognostic factors was evaluated by using log-rank test. Multivariate analysis was estimated by using the Cox proportional hazards model. The prognostic accuracy of the two staging systems was compared using receiver operating characteristic (ROC) analyses and the concordance index (C-index). Results: 5-year locoregional recurrence rate (LRR) for the whole group was 6.0%, 5-year distant metastasis (DM) rate was 11.5%, 5-year disease-free survival (DFS) was 85.0%, and 5-year overall survival (OS) was 93.1%. Cox analysis showed that 7th edition of the AJCC staging system and progesterone receptor status were independent risk factors for LRR, DM, DFS and OS (P<0.05). Compared with stage by 7th edition, 1 278(70.1%) were assigned to a different prognostic stage group: 1 088 (85.1%) to a lower stage and 190 (14.9%) to a higher stage. LRR, DM, DFS and OS were significantly different between prognostic stage ⅠA, ⅠB, ⅡA, ⅡB and ⅢA according to 8th edition of the AJCC staging system(P<0.001). Prognostic stage had significantly higher C-indexes and provided better estimation of prognosis compared to stage by 7th edition of the AJCC staging system (P<0.001). Conclusion: The prognostic stage groups of 8th edition AJCC staging system has superior prognostic accuracy compared to 7th edition in T1-2N1M0 breast cancer, and has better clinical therapeutic guidance value.

Abstract
WZ35 is a monocarbonyl analog of curcumin, which had been proved advantage over curcumin in chemical stability and antitumor activity. However, its pharmacokinetic profile has not been determined. In the present study, an ultraperformance liquid chromatography-tandem mass spectrometry assay was developed to detect concentration of WZ35 in rat plasma. Subsequently, pharmacokinetic study showed that the oral bioavailability of WZ35 is 10.56%. Cytochrome P450 (CYP450) plays a major role in metabolizing exogenous substance. The concentration of WZ35 was sharply decreased while incubating with microsome. It’s indicated that WZ35 is a substrate of CYP450s. Molecular docking assay showed that WZ35 can combine with CYP2B6 and CYP2C9 to form much more stable complex. The lowest docking energy was generated in complex with CYP2E1. The inhibition of CYP450s by WZ35 was also evaluated. Pan inhibitions of WZ35 on rat CYP3A2, CYP2B1, CYP2C11, CYP2D1, and CYP2E1 were observed by detecting probe substrates (midazolam, bupropion, tolbutamide, dextromethorphan, chlorzoxazone) and metabolites accordingly. On an average, 80% activities of enzymes were blocked. Mechanistically, the inhibitions of WZ35 on CYP3A2, CYP2B1, CYP2E1 were in a time-dependent manner according to the results of IC50 shift assay. The collective data demonstrated that the oral bioavailability of monocarbonyl analog of curcumin has significantly improved compared to curcumin. It’s both the substrate and inhibitor of CYP450s through in a time-dependent mechanism.
