Abstract
BACKGROUND Genomic changes that occur in breast cancer during the course of disease have been informed by sequencing of primary and metastatic tumor tissue. For patients with relapsed and metastatic disease, evolution of the breast cancer genome highlights the importance of using a recent sample for genomic profiling to guide clinical decision-making. Obtaining a metastatic tissue biopsy can be challenging, and analysis of circulating tumor DNA (ctDNA) from blood may provide a minimally invasive alternative. PATIENTS AND METHODS Hybrid capture-based genomic profiling was carried out on ctDNA from 254 female patients with estrogen receptor-positive breast cancer. Peripheral blood samples were submitted by clinicians in the course of routine clinical care between May 2016 and March 2017. Sequencing of 62 genes was carried out to a median unique coverage depth of 7503×. Genomic alterations (GAs) in ctDNA were evaluated and compared with matched tissue samples and genomic datasets of tissue from breast cancer. RESULTS At least 1 GA was reported in 78% of samples. Frequently altered genes were TP53 (38%), ESR1 (31%) and PIK3CA (31%). Temporally matched ctDNA and tissue samples were available for 14 patients; 89% of mutations detected in tissue were also detected in ctDNA. Diverse ESR1 GAs including mutation, rearrangement and amplification, were observed. Multiple concurrent ESR1 GAs were observed in 40% of ESR1-altered cases, suggesting polyclonal origin; ESR1 compound mutations were also observed in two cases. ESR1-altered cases harbored co-occurring GAs in PIK3CA (35%), FGFR1 (16%), ERBB2 (8%), BRCA1/2 (5%), and AKT1 (4%). CONCLUSIONS GAs relevant to relapsed/metastatic breast cancer management were identified, including diverse ESR1 GAs. Genomic profiling of ctDNA demonstrated sensitive detection of mutations found in tissue. Detection of amplifications was associated with ctDNA fraction. Genomic profiling of ctDNA may provide a complementary and possibly alternative approach to tissue-based genomic testing for patients with estrogen receptor-positive metastatic breast cancer.

Abstract
This study aimed to test the effects of xuezhikang, a cholestin extract that contains statin-like components, on arterial stiffness in patients with essential hypertension. One hundred hypertensive patients from the Chinese PLA General Hospital were randomly allocated to receive xuezhikang (1200 mg/day, orally) or placebo (same capsules containing only pharmaceutical excipients). Physical examination outcomes, lipid profile, high sensitivity C-reactive protein (hs-CRP) levels, matrix metalloproteinases-9 (MMP-9) levels, and arterial outcomes, including stiffness parameter (β), pressure-strain elasticity modulus (Ep), arterial compliance (AC), augmentation index (AI), and one-point pulse wave velocity (PWVβ) were obtained at baseline and after 6 months of the intervention. Xuezhikang significantly reduced β (8.4±3.1 vs 6.8±2.1, P=0.007), Ep (122.8±43.9 vs 100.7±33.2, P=0.009), PWVβ (6.7±1.2 vs 6.1±1.0, P=0.013), low-density lipoprotein cholesterol (3.4±0.6 vs 2.9±0.5, P=0.001), hs-CRP [2.1 (0.4-10.0) vs 1.4 (0.3-4.1), P=0.020], and MMP-9 (17.2±2.4 vs 12.7±3.8, P <0.001) compared to baseline. The placebo had no effect on these parameters. The changes of PWVβ in the xuezhikang group was significantly associated with the changes of hs-CRP and MMP-9 (r=0.144, P=0.043; r=0.278, P=0.030, respectively) but not with lipid profile changes. Our research showed xuezhikang can improve the parameters of arterial stiffness in hypertensive patients, and its effect was independent of lipid lowering.

Abstract
A simple and robust technique for directly measuring the loop gain and bandwidth of a phase-locked loop (PLL) is proposed. This technique can be used for the real-time measurement of the real loop gain in a closed PLL without breaking its locking state. The agreement of the measured loop gain and theoretical calculations proves the validity of the proposed measurement technique. This technique with a simple configuration can be easily expanded to other phase-locking systems whose loop gain and bandwidth should be measured precisely.

Abstract
BACKGROUND L-Tetrahydropalmatine (L-THP) is a tetra-hydro protoberberine isoquinoline alkaloid. The phyto-compounds bearing isoquinoline alkaloids have been reported to show a potential effect against a number of human cancers cell lines including leukemia. We hypothesized that L-THP, being an isoquinoline alkaloid, could be a potential molecule against acute lymphoblastic leukemia (ALL), in this study, we evaluate L-THP against p53 deficient leukemia EU-4 cell lines in vitro. METHODS For the study, p53 null leukemia EU-4 cells were used and treated with LTHP. The extent of apoptosis and viability of cells were determined. Expression of apoptosis related proteins such as XIAP and MDM2 was done by western blot and PCR studies. The expression of MDM2 and XIAP was knocked down by small interfering RNA (siRNA). RESULTS Outcomes of the study suggested that L-THP caused p53-indipendent apoptosis mediated by XIAP in EU-4 cells. The treatment of L-THP caused a decrease in the levels of XIAP protein with increasing dose and time. L-THP caused down-regulation of XIAP protein via inhibiting the expression of MDM2 and involving proteasomedependent pathway. Also, the outcomes of experiments suggested increased sensitivity of leukemia cells towards doxorubicin due to the inhibition of XIAP by L-THP or by siRNA. CONCLUSION Findings of the study confirm that L-THP resulted in p53 independent apoptosis via down-regulating XIAP protein by inhibiting MDM2 associated with proteasome-dependent pathway and increased sensitivity of EU-4 cells against doxorubicin. L-THP caused activation of caspase and resulted in apoptosis, L-THP may be a novel molecule for inducing apoptosis specifically in p53 null leukemia EU-4 cells.

Abstract
OBJECTIVE To analyze the current status of cholesterol goal attainment for the primary and secondary prevention of cardiovascular disease in dyslipidemia patients using data from the DYSIS-China study. METHODS Based on criteria defined in the 2014 China Cholesterol Education Program (CCEP) and the 2007 Chinese guidelines for the prevention and treatment of dyslipidemia in adults, 25 317 dyslipidemia patients enrolled in the DYSIS-China study (from March 2012 to October 2012) were stratified to the atherosclerotic cardiovascular disease(ASCVD) primary prevention and secondary prevention groups. The total cholesterol (TC) target goals were <3.11, 4.14, 5.18, and 6.22 mmol/L, respectively, and the low-density lipoprotein cholesterol (LDL-C) therapeutic goals were less than 1.8, 2.6, 3.4, and 4.1 mmol/L, respectively, for the very high-risk, high-risk, moderate-risk, and low-risk patients in the primary prevention group. The TC targets for the very high-risk and high-risk patients were <3.11 and <4.14 mmol/L, respectively, and the LDL-C targets were <1.8 and <2.6 mmol/L, respectively, in the secondary prevention group. The TC and LDL-C goal attainment rates were calculated for the different risk groups according to the targets values. RESULTS Totally, 71.09% (n=18 000) of the dyslipidemia patients were grouped into very high and high risk groups, 51.76% (n=13 104) and 48.24% (n=12 213) patients were stratified to primary and secondary prevention of ASCVD. The LDL-C and TC goal attainment rates for the secondary prevention group were 33.09%(4 041 cases) and 21.05% (2 571 cases), respectively. The LDL-C and TC goal attainment rates for the primary prevention group were 52.40% (6 866 cases) and 42.06% (5 511 cases), respectively. Multivariate logistic regression analysis showed that diabetes mellitus(OR=5.75, 4.15, P<0.05), coronary heart disease(OR=5.70, 3.58, P<0.001), and peripheral arterial disease(OR=2.42, 1.49, P<0.05) were risk factors for failure to achieve TC and LDL-C goals, respectively. CONCLUSIONS Despite the widespread application of the 2014 CCEP and 2007 Chinese dyslipidemia guidelines, LDL-C goal attainment among secondary and primary prevention patients remains suboptimal in China. More rigorous guideline adherence is therefore required to increase the LDL-C and TC goal attainment rates and improve the long-term cardiovascular outcomes in Chinese dyslipidemia patients.

Abstract
OBJECTIVE We aimed at identifying the predictive roles of Low-Density Lipoprotein Triglycerides (LDL-TG) for major adverse cardiovascular events (MACEs). PATIENTS AND METHODS A longitudinal study in a routine health check-up population was performed with an average follow-up of 4.8 years. The participants involved in this study were 1680, from 2007 to 2009, and all had followed-up for all-cause mortality, cardiovascular disease mortality, and the development of MACEs. The demographic information and anthropometric parameters at baseline were recorded. The baseline and follow-up conventional lipid parameters were measured. We also examined the level LDL-TG, as well as the relationship between its level and MACEs. RESULTS MACEs individuals were characterized by statistically higher baseline LDL-TG (17.22 ± 8.05 vs. 16.39 ±7.35 nmol/l, p = 0.017). The univariate regression for MACEs group indicated that the LDL-TG (b = 0.813, HR = 2.254, 95% CI: 1.454-3.494, p < 0.001), older age, sex and other factors were a significant risk for MACEs. Furthermore, in the adjusted Cox model showed that only higher baseline LDL-TG (b =0.512, HR = 1.669, 95% CI: 1.013-2.748, p = 0.044) and older age (b = 0.062, HR = 1.064, 95% CI: 1.034-1.094, p < 0.001, Table IV) were still predictors for MACEs. CONCLUSIONS Higher baseline LDL-TG closely associated with MACEs and it is a moderate and independent predictive factor for MACEs.

Abstract
We use a high harmonic generated supercontinuum in the soft X-ray region to measure X-ray absorption near edge structure (XANES) spectra in polythiophene (poly(3-hexylthiophene)) films at multiple absorption edges. A few-cycle carrier-envelope phase-stable laser pulse centered at 1800 nm was used to generate a stable soft X-ray supercontinuum, with amplitude gating limiting the generated pulse duration to a single optical half-cycle. We report a quantitative transmission measurement of the sulfur L2,3 edge over the range 160-200 eV and the carbon K edge from 280 to 330 eV. These spectra show all the features previously reported in the XANES spectra of polythiophene, but for the first time they are measured with a source that has an approximately 1 fs pulse duration. This study opens the door to measurements that can fully time-resolve the photoexcited electronic dynamics in these systems.

Abstract
The objective of this study was to investigate the clinical features of Kimura's disease in the head and neck region and to compare the local recurrence rate between three therapies used for the treatment of this disease. The clinicopathological information of 46 hospitalized patients suffering from Kimura's disease in the head and neck region over a 10-year period was reviewed retrospectively. All lesions were clinically observed in the head and neck region. These 46 patients underwent a total of 58 treatments; nine patients underwent multiple treatments due to local recurrence. Of the 58 treatments, 32 involved surgical excision alone, 24 involved surgical excision and postoperative low-dose radiotherapy (20-40Gy), one was a combination of ultrasound-guided core needle biopsy and radiotherapy, and one was a combination of incisional biopsy and subsequent radiotherapy. During the follow-up period, nine patients suffered 16 local recurrences. The recurrence rate of surgical excision combined with low-dose radiotherapy was much lower than that of surgical excision alone or radiotherapy alone (both P<0.05). It is concluded that Kimura's disease is a benign condition with a good prognosis, and surgical excision combined with postoperative low-dose radiotherapy is associated with the lowest local recurrence rate in the treatment of this disease.

Abstract
This study aimed to investigate the relationship between type I interferon (IFN-I) and plaque stability in pristane-treated apolipoprotein E-knockout (ApoE(-/-)) mice. Antinuclear antibody (ANA) and extractable nuclear antigen antibody (ENA) levels were measured by immunofluorescence and enzyme-linked immunospot assay. Atherosclerotic plaques were detected by Sirius red/fast green staining. Cell apoptosis was detected by terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick-end labeling. Gene expression was determined by real-time PCR analyses. We found that pristane-treated ApoE(-/-) mice developed a lupus-like syndrome characterized by an increased production of serum ANA and ENA. Pristane treatment decreased the collagen content and increased the number of apoptotic cells in plaques. Moreover, IFN-induced ISG15, IFIT1-1, and IFIT1-2 gene expression was increased in peripheral blood cells and aortic plaques. An IFN-α-stimulated macrophage supernatant inhibited collagen type I, alpha 1 gene expression in vascular smooth muscle cells. We concluded that the vulnerability of plaques was associated with the activation of IFN-I in pristane-treated ApoE(-/-) mice. Thus, we speculated that the higher prevalence of cardiovascular events in patients with systemic lupus erythematosus could be due to plaque instability.

Abstract
This study aims to evaluate the accuracy of endoscopic ultrasound (EUS) in the staging of esophageal cancer after neoadjuvant chemotherapy (NAC). Articles were searched in Medline, Pubmed, Cochrane Database of Systemic Reviews, Google scholar, and EMBASE. Two reviewers independently searched and extracted data. Meta-analysis of the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios (LR), and diagnostic odds ratio (DOR). Pooling was conducted using either fixed-effects model or random-effects model depending on the heterogeneity across studies. Sixteen studies (n = 724) were included in this analysis. The pooled sensitivity and specificity of EUS to diagnose T1 stage tumor was 23% (95% confidence interval [CI] 16-32%) and 95% (95%CI 93-97%), respectively. For T2 stage, EUS had a pooled sensitivity and specificity of 29% (95%CI 19-41%) and 84% (95%CI 77-88%). The pooled sensitivity and specificity of EUS were 81% (95%CI 72-88%) and 42% (95%CI 33-52%) in determining T3 stage tumor. To diagnose T4 stage tumor, EUS had a pooled sensitivity of 43% (95%CI 31-56%) and specificity of 96% (95%CI 94-97%), respectively. In determining N stage, the pooled sensitivity and specificity of EUS were 69% (95%CI 58-79%) and 52% (95%CI 42-62%). EUS is a moderately accurate technique in staging esophageal cancer after NAC. Its sensitivity is relatively high in T3 while specificity is high in other T stages (T1, T2, and T4). Tumors restaged by EUS as T4 should not be assigned to surgery because it is very likely to be inoperable. EUS is not reliable for N staging with its poor sensitivity and specificity. Subgroup analysis shows that staging accuracy did not improve with time.

Abstract
It has been well established that high-sensitivity cardiac troponin T (hs-TnT) is a specific and highly sensitive marker in acute coronary syndromes. On the other hand, studies on serum concentrations of hs-TnT in patients with hypertension in the absence of significant coronary stenosis are limited. Therefore, we hypothesized that hs-TnT levels are related to left ventricular (LV) remodeling and performance in hypertension. We included 537 hemodynamically stable hypertensive subjects, 247 males aged 60.7 ± 11.1 years, and 100 normotensive subjects of similar age and gender. Clinical examination, clinical assessment and laboratory assays were performed for all hypertensive and normotensive subjects. The detectable rate (>0.003 ng/mL) and elevated rate (>0.013 ng/mL) of hs-TnT were higher in hypertensive subjects than those in normotensive subjects. hs-TnT level gradually increased in hypertensive subjects with LV normal geometry, concentric remodeling, concentric hypertrophy and eccentric hypertrophy. hs-TnT was independently related to age, gender, hypertension, fasting blood glucose, renal function, and LV hypertrophy, and diastolic function on multiple analysis during the whole participation. An increase in hs-TnT levels could be a reliable biomarker of cardiac remodeling and function in hypertension, as an indicator of subclinical ongoing cardiomyocyte injury.

Abstract
The MYB gene is a master regulator of hematopoiesis and contributes to leukemogenesis in several species including humans. Although it is clear that MYB can promote proliferation, suppress apoptosis and block differentiation, the identities of the MYB target genes that mediate these effects have only been partially elucidated. Several studies, including our own, have collectively identified substantial numbers of MYB target genes, including candidates for each of these activities; however, functional validation, particularly in the case of differentiation suppression, has lagged well behind. Here we show that GFI1, which encodes an important regulator of hematopoietic stem cell (HSC) function and granulocytic differentiation, is a direct target of MYB in myeloid leukemia cells. Chromatin immunoprecipitation and reporter studies identified a functional MYB-binding site in the promoter region of GFI, whereas ectopic expression and small hairpin RNA-mediated knockdown of MYB resulted in concomitant increases and decreases, respectively, in GFI1 expression. We also demonstrate that GFI1, like MYB, can block the induced monocytic differentiation of a human acute myeloid leukemia cell line, and most importantly, that GFI1 is essential for MYB's ability to block monocytic differentiation. Thus, we have identified a target of MYB that is a likely mediator of its myeloid differentiation-blocking activity, and which may also be involved in MYB's activities in regulating normal HSC function and myeloid differentiation.

Abstract
BACKGROUND The basic studies showed that Pigment epithelium-derived factor (PEDF) plays an important role in inflammation. AIM This study aims to investigate the association of serum PEDF with high-sensitivity C-reactive protein (hs-CRP) in women with polycystic ovary syndrome (PCOS). METHODS Ninety-six PCOS women and 63 healthy, age-matched controls were enrolled in this study. Serum levels of PEDF, hs-CRP, Complement C3 (C3), glucose, insulin, lipids, and total testosterone were measured. Ninety-six PCOS women and 20 controls underwent hyperinsulinemiceuglycemic clamp to assess their insulin sensitivity, which was expressed as M value. RESULTS Serum PEDF levels and hs- CRP levels were much higher in PCOS women than in controls. In PCOS women, PEDF positively correlated with body mass index (BMI), hs-CRP, C3, LDL cholesterol (LDL-c), and systolic blood pressure (SBP), and negatively correlated with M value and HDL cholesterol (HDL-c). After controlling for BMI, PEDF was still positively correlated with hs-CRP. Multiple linear regression analysis revealed that in PCOS women, hs-CRP, SBP, LDL-c and M value were independent determinants of serum PEDF. CONCLUSION The serum PEDF levels are closely associated with hs-CRP in women with PCOS. PEDF may play a role in the development of chronic inflammation in PCOS.
