Abstract
BACKGROUND AND PURPOSE The aim was to determine the electroclinical findings in benign childhood focal epilepsy with vertex spikes (BEVS) with epileptic negative myoclonus (ENM) restricted to the lower limbs. METHODS The electroencephalogram database of Peking University First Hospital and medical records of patients with BEVS and ENM restricted to the lower limbs were reviewed. RESULTS Twenty-seven patients with BEVS had ENM restricted to the lower limbs. Twelve started as ENM restricted to the lower limbs. The age at seizure onset ranged from 1.5 to 4.8 years. During the course, half of the 12 patients developed focal sensorimotor seizures and then were diagnosed as benign childhood epilepsy with centrotemporal spikes (BECTS), with BEVS (four cases) and without BEVS (two cases). Five of them had electrical status epilepticus during sleep (ESES) and met the diagnostic criteria of atypical benign partial epilepsy (ABPE). Fifteen of the 27 patients had ENM restricted to the lower limbs during the course. The age at seizure onset ranged from 1.3 to 9.8 years. All had ESES and were diagnosed as ABPE, 11 as ABPE with BEVS and four as ABPE evolving into BEVS. CONCLUSIONS Benign childhood focal epilepsy with vertex spikes (BEVS) might represent a specific epileptic syndrome of the continuum of benign childhood focal epilepsy. ENM restricted to the lower limbs was a special phenomenon in BEVS. BEVS could overlap with BECTS or evolve into BECTS and further into ABPE and vice versa. Ignorance of vertex spikes with associated ENM restricted to the lower limbs might lead to a misunderstanding of BEVS, a specific type of benign childhood focal epilepsy.

Abstract
Abstract
Background: The benefit of repeat lumpectomy for ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery (BCS) is currently inconclusive. This issue has become even more important as small and isolated recurrent tumors were frequently diagnosed.
Methods: IBTR patients with definitive surgery were identified in the Surveillance, Epidemiology, and End Results registry between 1973 and 2013. The effect of different IBTR surgeries on overall and cancer-specific mortality was assessed using risk-adjusted Cox proportional hazard regression modeling and stratified propensity score matching analysis (PSMA).
Results: Based on the selection criteria, 5098 patients were recruited. Of those, 4048 (79.4%) women underwent mastectomy and 1050 (20.1%) underwent repeat lumpectomy after IBTR. Patients who received repeat lumpectomy had lower grade (23.7% vs 15% for well-differentiated) and smaller recurrent tumor (47% vs 36.2% for ≤ 1 cm) but earlier recurrence (23.9% vs 11.2% for interval times < 48 months) than those who underwent mastectomy. A minority of each group (24.7% of those undergoing repeat lumpectomy and 3% of the mastectomy group) underwent RT after surgery. In multivariable Cox regression analysis, repeat lumpectomy was associated with increased overall mortality (Hazard ratio (HR) = 1.58, 95% CI = 1.353 to 1.844, P < 0.001) and cancer-specific mortality (HR = 1.721, 95% CI = 1.345 to 2.202, P< 0.001). Similar HRs were derived from the PSMA cohort. However, we found no significant difference in overall mortality for women who underwent repeat lumpectomy followed by RT compared with that for those who underwent mastectomy (P= 0.411). Moreover, IBTR patients with small tumors (≤ 1 cm) who underwent repeat lumpectomy with RT rather than without had similar overall and cancer-specific survival rates to those who underwent mastectomy (P= 0.189 and P= 0.604, respectively).
Conclusions: Our investigation suggests that compared with mastectomy, repeat lumpectomy for IBTR is associated with higher overall and cancer-specific mortality under real-world observational conditions. Furthermore, repeat lumpectomy with RT is equivalent to mastectomy with respect to overall mortality and may influence treatment decision making for patients with small IBTR.

Abstract
Abstract
For the patients with breast cancer, the pathological status of axillary lymph nodes is one of the most important predictor of prognosis. In recent years, the application of sentinel lymph node biopsy has provided us with an opportunity for the further study on the mechanism of lymph node metastasis in breast cancer. Through detailed pathological examination of sentinel lymph nodes, we can easily find patients who are in the early stage of lymph node metastasis - that is, the tumor cells from the primary tumor, invading the lymph nodes and successfully colonized, but not yet break through the lymph node microenvironment defense to the subsequent lymph node. It is the most important stage during lymph node metastasis.
In the present study, we selected the pairing samples from breast cancer patients with early stage lymph node metastasis to carry out differential genomics research. A total of 182 genes with significant function and involved in significant signal transduction pathways were obtained. Bioinformatics method was used to screen out the mRNA, microRNA and transcription factor in the process of lymph node metastasis of breast cancer. We investigated the role of activated T cells c2 (NFATC2) in the core transcription factors as a target for further clinical and basic research.
The expression of NFATC2 was detected in the tissue microarray prepared from 200 patients with primary breast cancer. After the median follow-up period of 89.5 months, it showed that the prognosis of patients with NFATC2 overexpression was significantly better than that of the control group (p = 0.022). We also measured the expression of NFATC2 in 50 pairs of breast cancer patients with lymph node metastasis. The results showed that the expression of NFATC2 in the primary tumor was significantly higher than that in the matched lymph node, suggesting that in patients with breast cancer, the down-regulate or deficiency of NFATC2 expression may be related with lymph node metastasis. We also attempted to add the expression of NFATC2 as a new parameter in the prediction model of lymph node metastasis based on preoperative clinical and pathological parameters. The area under the ROC curve obtained in the newly established model was 0.767, the expression state of NFATC2 had impact on the performance of the prediction model. Furthermore, when we removed the NFATC2 parameter, it could reduce the area under the ROC curve in the validation group, suggesting that the expression of NFATC2 in the primary tumor may be used as a predictor of the pathological state of axillary lymph nodes.
In vitro and in vivo experiments, we demonstrated that NFATC2 has a significant suppression effect on the proliferation, migration and invasion of breast cancer cells. The potential NFATC2-target genes were determined by RNAseq and Chipseq. Nine differentially expressed genes were found to be regulated by NFATC2 in the Chip-seq analysis and bound to the promoter region of the gene, whereas GRAMD3 and SRGAP2 in the subsequent validation showed a positive correlation with the expression of NFATC2, suggesting that the two genes are likely to have a positive regulatory relationship with NFATC2.
This study clarifies that NFATC2 may represent a therapeutic target for early metastasis breast cancer.

Abstract
Objective: To investigate the clinical significance of soluble Semaphorin 5A(Sema 5A) in patients of rheumatoid arthritis(RA) and the effect of Sema 5A on osteoclastogenesis in RAW264.7 cells. Methods: (1)Soluble Sema 5A was detected in the serum of 62 RA patients, 30 osteoarthritis(OA) patients and 48 healthy controls(HC) by enzyme-linked immunosorbent assay(ELISA).The relationships between serum Sema 5A and disease activity, radiographic severity and laboratory parameters were investigated in RA patients.(2)RAW264.7 cells were treated with different concentrations of Sema 5A(0,0.5,1,2.5,5 μg/ml).After 7 days, tartrate-resistant acid phosphate(TRAP) staining was performed. The mRNA levels of TRAP, cathepsin-K and matrix metallopeptidase 9(MMP-9) were tested using real-time polymerase chain reaction (RT-PCR).(3)Bone resorption area of dentine slides cultured with RAW264.7 cells was calculated after Sema 5A(5μg/ml) treatment. Results: (1)The serum Sema 5A in RA patients[(5.24±0.59)μg/L] was significantly higher than those in healthy controls[(2.93±0.34)μg/L,P<0.01] and OA patients[(2.68±0.47)μg/L,P<0.05]. The Sema 5A level in RA patients was positively correlated with disease activity score with 28 joint using C-reactive protein(DAS28-CRP), clinical disease activity index (CDAI),C-reactive protein(CRP) and sharp scores(P<0.05 or P<0.01).In addition,the serum Sema 5A in RA patients with positive anti-cyclic citrullinated peptide(CCP) antibody was significantly greater than that of anti-CCP antibody-negative patients(P<0.05).(2)After RAW264.7 cells were treated with Sema 5A, the number of TRAP positive osteoclasts increased according to the increase of Sema 5A concentration with maximal effect at 5 μg/ml. Meanwhile, Sema 5A promoted mRNA expression of TRAP,Cathepsin-K and MMP-9.(3)Bone resorption area increased when RAW264.7 cells were treated with Sema 5A(5 μg/ml). Conclusions: Serum Sema 5A is elevated in RA patients and correlated with disease activity and radiographic severity. Sema 5A promotes osteoclastogenesis of RAW264.7 cells.

Abstract
OBJECTIVE To investigate the clinical significance of high-frequency oscillations (HFOs) on scalp electroencephalography (EEG) in patients with epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS). METHODS Twenty-one CSWS patients treated for epilepsy from January 2006 to December 2016 in Pediatric Department of Peking University First Hospital were enrolled into the study. Selected clinical variables including gender, age parameters, seizure frequencies and antiepileptic drugs were compared between (a). HFO-positive group and HFO-negative group before methylprednisolone treatment and (b). excellent seizure outcome group and not-excellent seizure outcome group after methylprednisolone treatment. Interictal HFOs and spikes in pre- and post-methylprednisolone scalp EEG were measured and analyzed. RESULTS Before methylprednisolone treatment, there were 12 of 21 (57%) CSWS patients had HFOs, with a mean value 43.17 per 60 s per patient. The 12 patients with HFOs tended to have more frequent epileptic negative myoclonus/atonic/myoclonus/atypical absences than those without HFOs in a month before methylprednisolone treatment. A total of 518 HFOs and 22 592 spikes were found in the pre-methylprednisolone EEG data of 21 patients, and 441 HFOs (86%) were associated with spikes. The highest amplitudes of HFOs were significantly positively correlated with that of spikes (r=0.279, P<0.001). Rates reduced by methylprednisolone treatment were statistically significant for both HFOs (P=0.002) and spikes (P=0.006). The percentage of reduction was 91% (473/518) and 39% (8 905/22 592) for spikes and HFOs, respectively. The percentage of spike and HFOs changes was respectively 100% decrease and 47% decrease in the excellent seizure outcome group, and they were 79% decrease and 18% increase in the not-excellent seizure outcome group. CONCLUSION Prevalence of HFOs might reflect some aspect of epileptic activity. HFOs were more sensitive to methylprednisolone treatment than spikes and had a good correlation with the prognosis of seizures, and HFOs could be applied to assess epilepsy severity and antiepileptic therapy.

Abstract
Abstract
Background
Long non-coding RNAs (lncRNAs) have been proved to play an essential role in cancer metastasis. The accuracy of intraoperative assessment of lymph nodes metastasis need to be improved. In this study, we aimed to define the lncRNA biomarker ectopic expressed in breast cancer patients' metastatic lymph nodes, and to explore the potential molecular mechanisms.
Experimental Design
RNA-seq analyses in 3 paired breast cancer patients' primary tumor and metastatic lymph node was used as training set to determine differentially expressed lncRNAs that may be associated with lymph node metastasis. The other 40 patients were analyzed as validation set to test the accuracy of lncRNAs identification by quantitative real-time PCR. The correlation between LOC283299 expression level and prognosis in other 282 breast cancer patients was confirmed. In parallel, in vitro and in vivo analyses were carried out to determine the potential mechanisms of LncRNA-dependent lymph node metastases and prognosis.
Results
RNA-seq analyses in the training set revealed significant correlation between high expression level of LOC283299 and lower lymph node metastasis potential in breast cancer patients. We further validated that the expression level of LOC283299 was significantly higher in tumor primary tissue than that in paired metastatic lymph node (P=0.0245), and higher LOC283299 expression level was markedly associated with good metastasis-free survival in breast cancer patients (P=0.04). In breast cancer cell lines, CRISPR-on overexpression of LOC283299 inhibited proliferation, migration, invasion, and metastases both in vivo and in vitro. shRNA knockdown LOC283299 promotes the ability of tumor proliferation and metastasis. The molecular mechanisms by which LOC283299 as metastasis-suppressing lncRNAs regulates recurrence and metastasis may involve regulation of epithelial to mesenchymal transition (EMT), cellular invasion and microenvironment in breast cancer cells.
Conclusion
Our study revealed a strong correlation between LOC283299 expression and lymph node metastases in breast cancers. High level of LOC283299 was associated with better metastasis-free survival. The changed metastasis phenotype may be mediated by the interaction of LOC283299 and breast cancer cells. Therefore, LOC283299 may represent a potential predictive biomarker for early lymph node metastasis in breast cancer.

Abstract
PURPOSE HO-1 has been proved to be associated with tumor aggressivity and poor prognosis in various cancers. Our study provides the first study to demonstrate the relationship of HO-1 expression and clinical characteristics in ovarian cancer patients. METHODS Immunohistochemistry and western blotting were used to examine the expression of HO-1 in tissue species and fresh tissues. CCK-8 was used to investigate cell viability. Transwell chamber was performed to estimate migration and invasion capacities in A2780 and Skov-3 cells. RESULTS Immunohistochemistry and western blotting showed that the expression of HO-1 was higher in ovarian cancer tissues than normal ovarian tissues. High expression of HO-1 was significantly associated with serous ovarian cancer, high FIGO stage, lymph node metastasis, and non-optimal debulking. Patients with high expression of HO-1 exhibited an unfavorable prognosis. In vitro inducing the expression of HO-1 promoted the proliferation and metastasis of A2780 and Skov-3 cells, with the increased expressions of mesenchymal marker (Vimentin), epithelial-mesenchymal transition-associated transcript factor (Zeb-1), anti-apoptotic protein (Bcl-2), and the decreased expressions of epithelial marker (Keratin) and pro-apoptotic protein (Bax). Meanwhile, after incubating A2780 and Skov-3 together with HO-1 inhibitor, above results could be reversed. CONCLUSION HO-1 might be a potential marker for prediction of ovarian cancer prognosis and a target for ovarian cancer treatment.

Abstract
BACKGROUND AND PURPOSE Inflammation comprises important aspects of large-artery atherosclerosis (LAA) stroke pathophysiology. YKL-40 is a new and emerging biomarker that is associated with both acute and chronic inflammations. Elevated serum concentrations of YKL-40 have been reported in patients with atherosclerosis and other cardiovascular diseases. This study investigates whether serum YKL-40 concentrations on admission can predict 3-month clinical outcomes after LAA stroke. METHODS We recruited control patients (n=85) and those with LAA stroke (n=141) according to the TOAST classification system. The modified Rankin scale at 3 months after stroke was used to evaluate the prognosis. The prognostic accuracy was assessed by the receiver operating characteristic curve. RESULTS Serum YKL-40 level was significantly higher for LAA patients than for controls (P<.001). Patients with poor outcomes (n=36) had significantly increased serum YKL-40 concentrations on admission (P=.01). High YKL-40 levels predicted poor functional outcome (OR=6.47, P=.02). Moreover, the combination of YKL-40 level and the NIHSS score could improve the prognostic accuracy of the NIHSS in predicting functional outcome (combined areas under the curve, 0.87; 95% CI, 0.80-0.94; P<.001). CONCLUSIONS The level of serum YKL-40 is a significant and independent biomarker to predict the clinical outcome of LAA stroke.

Abstract
OBJECTIVE To analyze the clinical and genetic characteristics of patients with pyridoxine dependent epilepsy (PDE), and build a method to detect and analyze the concentration of urinary pipecolic acid in PDE patients receiving pyridoxine treatment. METHOD Twelve patients (8 were male, 4 were female) were diagnosed as PDE in Peking University First Hospital between April 2012 and September 2015. The clinical manifestations, diagnosis and treatment process, video-electroencephalogram, magnetic resonance imaging were retrospectively analyzed. ALDH7A1 gene was detected using Sanger sequencing or targeted next-generation sequencing. The concentration of urinary pipecolic acid in PDE patients was detected with gas chromatography-mass spectrometry (GC-MS), as well as in some non-PDE children served as normal control. All controls, 58 cases totally, were neonates born in our hospital or children came to our hospital for reasons such as syncope (without disturbing pipecolic acid metabolism) from November 2015 to January 2016. Of them, 25 were ≤6 months old(14 were male, 11 were female), 33 were >6 months old(14 were male, 19 were female). The Student's t-test or Mann-Whitney U test was used for comparing the pipecolic acid between the two groups. Correlation analysis was conducted using Pearson or Spearman test. RESULT Of the 12 patients, seven of them were abnormal at birth. The age of epilepsy onset was from 5 h to 5 months, within 10 d in 8 patients. After a diagnostic delay time of 15 d to 20 months, seizures in all patients were controlled by pyridoxine monotherapy, at a dose of higher than 10.0 mg/(kg·d) in 10 patients, and 8.5 and 2.5 mg/(kg·d) in the other 2 patients respectively. The range of maintenance dose was 2.5-20.0 mg/(kg·d) during the follow up. Interictal electroencephalogram showed nonspecific abnormality in 10, normal in 2. Brain magnetic resonance imaging showed nonspecific abnormality in 7, normal in 5. ALDH7A1 mutations were found in all patients, including 15 different mutation sites, four of which were never reported before. Splicing mutation IVS11+ 1G>A was carried in 6 patients, with a frequency of 25% (6/24). At the last follow-up, eleven patients were in various degree of psychomotor development delay, including the 4 patients with severe delay in whom birth abnormalities presented, and no significant delay was found in one patient. The concentration of urinary pipecolic acid in control: age ≤6 months, median 8.47 (0.46-35.33) mmol/mol creatinine; age >6 months, median 0.66 (0.12-3.52) mmol/mol creatinine. The concentration of urinary pipecolic acid was different between two groups of control (Z=-5.464, P<0.01). Twelve patients were all older than 6 months when they were tested, and the concentration was only mildly elevated in one patient, the range of 12 patients was 0.14-4.08 mmol/mol creatinine. The concentration was not significantly different between the control with age >6 months and our PDE patients (Z=-0.655, P>0.05). There were no significant correlations between the concentration of urinary pipecolic acid and the initial dose or maintenance dose at last follow-up of pyridoxine (r=0.418 and 0.166, P=0.176 and 0.607). CONCLUSION Seizures start in early infancy in most PDE patients. The splicing mutation IVS11+ 1G>A is supposed to be a probable"hotspot"mutation with a high frequency in Chinese PDE patients. Most patients have different levels of psychomotor development delay after seizures are controlled, and the patients with birth abnormalities may have worse outcomes. No relationships between the diagnostic delay time and the development outcome are found. The concentration of urinary pipecolic acid can return to normal during treatment with pyridoxine.
