Abstract
Objective: To analyze the risk factors of perioperative complications within 30 days of carotid endarterectomy(CEA) in the treatment of carotid atherosclerosis stenosis(CAS) during 2011-2017, and to discuss the techniques for reducing the perioperative complication rates. Methods: From August 2011 to August 2017, 486 patients with CAS were retrospective included, and 61 of them underwent bilateral CEA, with a total of 547 cases of CEA included. Perioperative complications were collected within 30 days after operation, and the risk factors related to perioperative complications were analyzed by statistical analysis. Results: In total 547 cases, 12 cases had a postoperative stroke, while 1 case died. A total of 7 cases underwent cranial nerve injury, and 5 cases had an incision related complications. In chi-square test analysis, data suggested that there was a significant difference in the incidence of complications in patients with heart disease, preoperative neurological score difference, contralateral carotid serious stenosis or occlusion and intraoperative shunt in CCA/ICA technique application (P<0.05). In the multivariate Logistic regression, it suggested that poor preoperative neurological score and contralateral carotid serious stenosis or occlusion were independent risk factors for perioperative stroke and death. Conclusion: Our results showed that CEA is effective to prevent stroke and treat patients with CAS. Patients with poor preoperative neurological score and contralateral carotid serious stenosis or occlusion may increase the risk of postoperative stroke rates.

Abstract
BACKGROUND The compromise of blood brain barrier (BBB) integrity is often associated with human hemorrhage stroke and neurodegeneration diseases, including retina diseases, such as age-related macular degeneration and diabetic retinopathy. Brain pericytes play pivotal roles in regulation and maintenance of BBB integrity. However, the mechanisms underlying brain pericyte development to establish BBB integrity remain unclear. METHODS Zebrafish transgenic lines Tg(flk1:GFP; gata1:dsRed), Tg(flk1:GFP), Tg(fli1:GFP) and Tg(BRE:GFP) were used in this work. The functional studies of bmp3 were performed by mopholino oligonucleotide (MO) injection, dye-based permeability assay, RT-PCR, in vivo imaging, immunofluorescence staining and statics analysis. RESULTS Here we report that bmp3 regulates BBB integrity in zebrafish brain by promoting pericyte development. Knockdown of bmp3 with injection of bmp3-MO causes intracerebral hemorrhage in zebrafish embryos. Meanwhile, disruption of bmp3 function by bmp3-MO injection impairs cerebral pericyte coverage in zebrafish embryos. Mechanistically, knockdown of bmp3 disrupts the pattern and activities of BMP signaling in zebrafish brain, thus probably disrupting the balance of TGFβ/BMP signaling in zebrafish embryos. CONCLUSION In summary, our data shows that bmp3 regulates BBB integrity potentially by promoting pericyte development.

Abstract
Objective: To analyze serologic surveillance indicators during pregnancy among syphilis-infected women who delivered in 2013 in East China. Methods: Data were from national 'Information System of Prevention of Mother-to-child Transmission of HIV, syphilis and HBV Management' and in total 5 206 syphilis-infected pregnant women who delivered in 2013 and in East China were involved in the analysis. Information on demographic characters, laboratory tests, and treatment regimens were collected. The maternal non-treponemal testing surveillance and titer distribution were described and compare the proportions between pregnant women receiving standard testing and non-standard testing, taking baseline testing and testing before delivery or at the third trimester. Multivariate logistic regression model was analyzed using maternal titer control as dependent variable, using prior history of syphilis infection, syphilis stages, titer, gestational weeks of treatment initiation and treatment regimens as independent variables in 3 940 pregnant women with both baseline testing results and testing results before delivery or at the third trimester. Results: The ages of the 5 206 syphilis infected pregnant women were (28.1±5.8) years old. The numbers of women received penicillin treatment, other treatment regimens and no treatment were 2 967 (57.0%), 281 (5.4%), and 1 958 (37.6%), respectively. The number of women with maternal seroconversion, 4-fold or greater titer decline, or titer increase were 349 (6.7%), 251 (4.8%) and 28 (0.5%). Multivariate analysis results showed that compared with pregnant women with prior history of syphilis, the OR(95%CI) for maternal titer control was 1.49 (1.18-1.88) among those with syphilis-infection history. Compared with pregnant women initiated treatment at 28 gestational weeks or before, the OR (95%CI) for maternal titer control was 4.09 (3.19-5.24) among those who initiated treatment after 28 gestational weeks. Compared with pregnant women initiated treatment at 28 gestational weeks or before, the OR (95%CI) for maternal titer control was 4.09 (3.19-5.24) among those who initiated treatment after 28 gestational weeks or received no treatment. Compared with pregnant women received penicillin treatment, the OR (95%CI) for maternal titer control among those received non-penicillin treatment and those received no treatment were 2.35 (1.46-3.76) and 1.55 (1.13-2.12), respectively. Conclusion: In East China, the proportion of women achieved seroconversion or 4-fold or greater titer decline during pregnancy was very low. Pregnant women with no prior history of syphilis infection, early maternal initiation of treatment, and penicillin treatment were more likely to reach maternal titer control.

Abstract
Ghrelin is a novel growth hormone (GH)-releasing peptide, which has been identified as an endogenous ligand for the GH-sretagogue receptor. The sequence and expression of ghrelin has been determined in many species. In this study, to reveal the molecular characterization and expression patterns of ghrelin in the reindeer (Rangifer tarandus), the full-length DNA and cDNA encoding ghrelin were cloned from reindeer stomach using genome walking and rapid amplification of complementary deoxyribonucleic acid ends (RACE). The expression of ghrelin in almost all tissues was examined by real-time quantitative PCR (RT-qPCR). The 4076 bp amplicon of the ghrelin gene consisting of 4 exons and 3 introns was cloned from reindeer. Results of cDNA cloning and sequence analysis revealed that the full-length ghrelin cDNA was composed of 539 bp that included a 5'-untranslated region (46 bp), an open reading frame (ORF) (351 bp), and a 3'-untranslated region (142 bp). In addition, ghrelin was expressed in the all tissues examined, with the expression in the abomasum significantly higher than that in other tissues (p<0.05), followed by the pancreas, duodenum, testis and oesophagus. The results show that the expression of ghrelin in the reindeer gastrointestinal tract is extensive, suggesting its may have a role in regulating the digestive function.

Abstract
Objective: To investigate an effect on speech recognition after bilateral cochlear implants(CI) simultaneously. Methods: Nine subjects who underwent bilateral CI operation simultaneously in Peking Union Hospital in 2007 were assigned as bilateral group, another 9 subjects with unilateral CI were chosen as unilateral group according to the age, gender, duration of deafness. Hearing threshold, speech recognition of phrases, disyllabic words, single word in quiet and noise environment were calculated, respectively. Three different sound source positions were set up to simulate the three effects of binaural hearing (head shadow, binaural redundancy and binaural squelch) in noise environment. The speech signal intensity was 70 dBSPL, the signal to noise ratio (SNR) was 0 dB, + 4 dB, + 8 dB, and the speech recognition of phrases were examined in bilateral CI group. All the data was analyzed by SPSS 19.0 software. Results: In quiet environment, the average aid-hearing threshold was significantly reduced as (7.2±3.0)dB in bilateral CI group compared to unilateral CI group(P<0.05). However, the speech recognition of phrases, disyllabic words, and single word in quiet and noise environment did not show significant differences between bilateral CI and unilateral CI groups (P>0.05). In the testing under noise environment, the speech recognition of bilateral CI group was significantly higher than that of unilateral CI group (P<0.05). In the estimation of noise environment (SNR=+ 8), the phrase test and speech recognition of head shadow model in bilateral groups were significantly better than that of unilateral group (P<0.01). Further, bilateral CI group showed statistical significances in binaural redundancy and binaural squelch models(P<0.01), there was statistically significant were also found difference between two groups (P<0.01); Bilateral CI group did not reveal significant difference compared with unbilateral CI group in binaural squelch model(P>0.05). Under different signal-to-noise ratio (SNR=+ 8, + 4) noise environment, all the three given models in bilateral CI group show higher signal-to-noise ratio, higher speech recognition rate (Independent-Samples t test, P<0.01). In addition, head shadow model presented negative influences on speech recognition rate compared with binaural redundancy and binaural squelch model by SNR(P<0.05). SNR influences on binaural redundancy and binaural squelch model were almost identical, F=0.371, P=0.549. Conclusion: The subjects who underwent simultaneous bilateral cochlear implantation could significantly reduce aid-hearing threshold, and greatly improve the speech recognition of phrases, disyllabic words, and single word under noise environment.

Abstract
In this study, polydimethylsiloxane and graphene were used to fabricate surface electrodes for electrocardiographic (ECG) sensing. A simple and inexpensive method was developed to fabricate graphene-based polymer films. In this method, graphene was inlaid in polydimethylsiloxane by polymer infiltration. The polymer films were successfully used in ECG measurements and performed as well as conventional silver/silver chloride wet electrodes. Few motion artifacts were observed with the graphene films when body postures were changed and during walking. The presented approach is low-cost and suitable for mass production, holding great promise in fabricating polymer electrodes for medical monitoring.

Abstract
Human endogenous retroviruses (HERVs) play pivotal roles in the development of breast cancer. However, the detailed mechanisms of noncoding HERVs remain elusive. We used RNA-Seq to analyze the transcription level of each HERV loci across the genome in eight pairs of triple negative breast cancer (TNBC) and normal breast tissues. We identified one LTR70, which we dubbed TROJAN, was a TNBC related HERV. We also found that HERVs could not be researched as families because each members from the same family had different expression patterns in TNBC. TROJAN promoted proliferation and invasion in TNBC cells and indicated poor outcomes in patients. Here, we confirmed that TROJAN regulated the progression of TNBC through multiple mechanisms, with ZMYND8, a metastasis-repressing factor, being one of the targets of TROJAN. TROJAN could bind to ZMYND8, promoting its degradation through ubiquitin-proteosome system, and downregulated the transcription level of EGFR, thus stimulating the metastasis of TNBC. The association of TROJAN, ZMYND8, and EGFR was subsequently confirmed in clinical samples. Furthermore, our study verified that the therapeutic delivery of antisense oligonucleotides targeting TROJAN significantly suppressed metastasis of TNBC in vivo. In conclusion, TROJAN promotes the progression of breast cancer and serves as a potential therapeutic target in TNBC.

Abstract
Synovial abnormalities have been observed at multiple stages of osteoarthritis (OA). Increasing evidence suggests that it may play an important role in the OA pathological process. Many assessment systems using magnetic resonance imaging (MRI) and ultrasound have been established to detect synovial inflammation in OA. These have been used to inform the current investigation of OA disease phenotypes and progression and can be utilised in the future for clinical trials developing potential treatments. This narrative review aims to illustrate the importance of synovial tissue in OA and provide an overview of imaging assessments and possible therapies targeting synovial abnormalities.

Abstract
BACKGROUND The value of maximum standard uptake value (SUVmax) was overlooked in current studies comparing stereotactic body radiotherapy (SBRT) versus surgery for stage I non-small cell lung cancer (NSCLC). Herein, we aimed to compare the 3-year outcomes based on patients for whom SUVmax were available, and to explore the role of SUVmax in clinical decision-making. METHODS From January 2010 to June 2016, data of eligible patients were collected. Patient variables and clinical outcomes were compared in both unmatched and matched groups using propensity score matching (PSM). Multivariate analysis was performed for predictors of poor outcome. The relationship between treatment approach and survival outcome was also evaluated in subgroup patients stratified by SUVmax level. RESULTS A total of 425 patients treated with either surgery (325) or SBRT (100) were included. Patients receiving SBRT were significantly older, had a higher level of SUVmax and were more likely to have tumor of centrally located. Multivariate analysis showed that SUVmax and tumor size were significant predictors for 3-year OS, LRC, and PFS, while better PFS was also related to peripheral tumor and surgery. The result of PSM analysis also showed that compared to SBRT, surgery could only achieve better PFS. Subgroup analysis indicated that surgery had added advantage of 3-year LRC and PFS for patients in high SUVmax group (SUVmax > 8), but not in low SUVmax group. CONCLUSIONS The study found a superior PFS after surgery while OS and LRC did not differ between SBRT and surgery. Surgery should be recommended for tumor of high SUVmax.

Abstract
OBJECTIVE Although the frontolimbic cortex has been implicated in borderline personality disorder (BPD), information about possible asymmetries in this region in patients with BPD is limited. This study aimed to examine whether frontolimbic cortex asymmetries differ between patients with BPD and healthy individuals. METHODS The brains of 30 young adult patients with BPD and 32 healthy control subjects were scanned with magnetic resonance imaging (MRI). The participants completed self-report scales assessing impulsivity, affect intensity and other psychological variables. Gray matter volume, surface area, and cortical thickness in regions of interest (ROIs), namely anterior insula (AI) and anterior cingulate cortex (ACC) were determined and the data were probed for hemisphere-group interactions. RESULTS Relative to controls, patients with BPD had reduced cortical thickness in left ACC and less surface area and gray matter volume in left AI. Significant group-hemisphere interactions were observed for gray matter volume and surface area of AI and for cortical thickness of ACC. Post hoc analysis showed that the BPD patients had greater frontolimbic cortex asymmetry than healthy controls; furthermore, greater asymmetry of AI&ACC correlated with a higher score in attention subscale of Barratt Impulsiveness Scale. CONCLUSION Patients with BPD have greater frontolimbic asymmetry than healthy individuals.

Abstract
Holistic integrative medicine (HIM), as one of the important ideas in the field of medicine, arouses great concern recently. HIM regards the human body as a whole, turns data and evidence in medical research back to facts, integrates technologies and experience developed in clinical research into medical skills. The repeated practices at the levels of fact, experience, and medical skills will generate true knowledge to solve the wide spread problems brought by linearized thinking and fragmented knowledge. With the development of highly divided medical disciplines, how to utilize and practice HIM has become a common concern of the medical community. Specialization of stomatology, which is a first level discipline like medicine, has also become a trend for years. However, holistic concept cannot be overlooked, especially in the development of oral medicine. This article aims at the communication and exchange of knowledge about HIM among dental professionals. In order to serve the patients better, the authors look forward to practicing the HIM concept in the field of oral medicine through the efforts of us all.

Abstract
OBJECTIVE To develop a measure of knee joint effusion-synovitis volume and to examine the effect of vitamin D supplementation on effusion-synovitis in people with knee osteoarthritis (OA) and low vitamin D levels over 24 months. METHOD Symptomatic knee OA patients with low 25-(OH)D levels (12.5-60 nmol/l) were recruited for a multi-centre, randomised, placebo-controlled and double-blind trial. Participants (age 63 ± 7 years, 208 females) were allocated to either 50,000 IU monthly vitamin D3 (n = 209) or placebo (n = 204) for 24 months. Knee effusion-synovitis volume in suprapatellar and other regions was measured on magnetic resonance imaging (MRI) using OsiriX software. The intra-class correlation coefficients (ICCs) were used to test inter- and intra-rater reliabilities. The least significant change criterion was used to define the increase/decrease in effusion-synovitis volume. RESULT The reproducibilities of effusion-synovitis volume measurement were high with ICCs ranging from 0.93 to 0.99. Over 24 months, effusion-synovitis volume remained stable in the vitamin D group but increased in placebos with a significant between-group difference (-1.94 ml, 95% confidence interval (CI): -3.54, -0.33). This effect was evident in those with baseline effusion-synovitis and with suprapatellar effusion-synovitis. The proportion with an increase in effusion-synovitis volume was lower in the vitamin D group than placebo (risk ratio (RR): 0.87, 95% CI: 0.77, 0.97). CONCLUSION This highly reproducible effusion-synovitis volume measurement could be a promising outcome measure in OA trials. Vitamin D supplementation could retard the progression of effusion-synovitis which can potentially benefit people with an inflammatory OA phenotype.

Abstract
Approximately, 240 million people have chronic hepatitis B worldwide, with mother-to-child-transmission (MTCT) accounting for most cases. Therefore, Henan Province, China launched a public health programme to prevent MTCT. To determine the efficacy of this health programme, a survey was carried out in Huixian and Xinan counties, which are located in northern and western Henan. All infants born in these two counties between January 1, 2013 and March 31, 2014 to a mother positive for hepatitis B surface antigen (HBsAg) were surveyed. In total, there were 438 mother-infant pairs. A blood sample was collected from all mothers and infants and the following Hepatitis B virus (HBV) markers, antibodies, and antigens were measured: HBsAg, anti-HBs, anti-HBc, HBeAg, anti-HBe, and HBV-DNA. All mothers and 5.3% (23/438) of the infants were HBsAg positive. All infants received three doses of the hepatitis B vaccine (HepB) and the postvaccination serological test (PVST) showed that the appropriate interval for PVST may be 1-8 months after the final HepB dose. Multivariable analysis showed that infants without a timely first and second dose of the HepB, with an HBeAg-positive mother and mothers who had not received hepatitis B immune globulin during pregnancy were implicated in MTCT. The stratified analysis using maternal HBeAg as a marker showed that maternal HBeAg may be a strong risk factor for MTCT. To prevent MTCT in middle China, several courses of action are recommended. The first is to optimize the screening method for the mother to allow HBeAg and HBsAg-positive mothers to receive medical treatment during pregnancy and a timely birth dose of the vaccine to all infants. Second, all infants with an HBsAg-positive mother should be tested for anti-HBs and HBsAg at 7-14 months old and any anti-HBs-nonresponse infants should receive an additional three dosesof the vaccine.

Abstract
Objective: To explore the effects of scar excision combined with negative-pressure on repair of hypertrophic scar in burn children. Methods: From October 2010 to August 2016, 25 children with hypertrophic scar after deep burn were hospitalized, with scar course ranging from 3 months to 11 years and scar area ranging from 35 to 427 [83(51, 98)]cm(2). A total of 35 scars of 25 children were located in trunk (11 scars), upper limb (11 scars), and lower limb (13 scars). All children received scar excision operation and negative-pressure treatment (negative-pressure value ranged from -40 to -20 kPa), among which 6 cases received scar excision operation and negative-pressure treatment for two times for further removal of scars. After scar excision, electronic spring scale was used to measure the tension of the incision. The tension value of children ranged from 3.43 to 23.84 [7.16 (5.59, 9.12)] N, and then the incision was closed with appropriate suture according to the value of the tension. The incision with smaller tension was firstly opened on post operation day (POD) 8. After removing the suture, negative-pressure was conducted to POD 14. The incision with larger tension was firstly opened on POD 12. After removing the suture, biological semi-membrane was used to reduce tension to POD 16. All healed incisions were performed with anti-scar treatment for 1 year and relaxation and fixation for 3 months. General condition of the incision was observed after operation. The reduction percentage of scar area was calculated half-year after operation. The Patient and Observer Scar Assessment Scale was used to record the overall score of scar and scar score of trunk, upper limb, and lower limb before operation and half-year after operation. Data were processed with paired t test and Wilcoxon rank sum test. Results: After removing the suture, all incisions of children healed well without redness, effusion, and rupture. Half-year after operation, the appearance and deformity of incision were obviously improved, and the symptoms including pruritus and pain were basically relieved. Half-year after operation, the scar area of children ranged from 0 to 174 [21(9, 47)]cm(2,) which was significantly decreased as compared with that before operation (Z=-5.16, P<0.05). The reduction percentage of scar area ranged from 36% to 100% [(73±19)%]. Half-year after operation, the overall score of scar and scar score of trunk, upper limb, and lower limb of children were obviously decreased as compared with those before operation (with t values from 6.42 to 17.37, P values below 0.05). Conclusions: Scar excision combined with negative-pressure treatment has a good clinical effect on repair of hypertrophic scar in burn children, which is suitable for clinical application.

Abstract
Abstract
Background: A high quality programmed cell death ligand-1 (PD-L1) diagnostic may help to identify patients (pts) most likely to respond to anti-PD-L1/programmed cell death-1 (PD-1) therapy. Here we describe a PD-L1 immunohistochemical (IHC) diagnostic test developed for urothelial carcinoma (UC) pts treated with durvalumab.
Methods: The IHC assay uses an anti-human PD-L1 rabbit mAb optimized for detection of both tumor cell (TC) and tumor-associated immune cell (IC) PD-L1 expression with the OptiView DAB IHC Detection Kit on the automated VENTANA BenchMark ULTRA platform. The assay was validated for intended use in UC formalin-fixed, paraffin-embedded samples in a series of studies that addressed sensitivity, specificity, robustness and precision and implemented in Study CD-ON-MEDI4736-1108 (NCT01693562). Pts were evaluated using the VENTANA PD-L1 (SP263) Assay at a prespecified PD-L1 expression cut-off. Efficacy was analyzed in pts with PD-L1 low/negative (defined as TC <25% and IC <25%) UC and in pts with PD-L1 high (defined as TC ≥25% or IC ≥25%) UC.
Results: The VENTANA PD-L1 (SP263) Assay met all the predefined acceptance criteria (average positive agreement and average negative agreement >85%), showing analytical specificity, sensitivity and precision. It demonstrated ≥97% and ≥85% inter-reader precision agreement for TC and IC respectively. For intra-reader precision, it demonstrated >96% and >87% agreement for TC and IC respectively. For intra-day performance, the assay demonstrated ≥96% agreement for TC and IC and for inter-day performance, it demonstrated ≥98% and 100% agreement for TC and IC respectively. Precision studies for inter-antibody lot, inter-detection kit lot and intra-platform demonstrated >97% agreement for both TC and IC. Inter-laboratory testing was performed at 3 external laboratories and demonstrated an overall agreement rate of 92.3%. The VENTANA PD-L1 (SP263) Assay was implemented in Study CD-ON-MEDI4736-1108 and durvalumab demonstrated clinical activity and durability of response in both PD-L1 high and PD-L1 low/negative subgroups, yet with different response rates. In addition, given the high negative predictive value of the assay, it is especially helpful in evaluating the likelihood of response to durvalumab; pts who were classified as PD-L1 high with the VENTANA PD-L1 (SP263) Assay tended to have a higher objective response rate per RECIST v1.1 than pts who were PD-L1 low/negative.
Conclusions: These data show that determination of PD-L1 expression in TC and IC in UC pts using the VENTANA PD-L1 (SP263) Assay is precise and highly reproducible and highlight the utility of the assay in a clinical setting. The VENTANA SP263 Assay is especially helpful in informing pts and physicians on the likelihood of response to durvalumab, but not for the purpose of restricting treatment to only PD-L1 high pts.

Abstract
Abstract
Background: Determination of programmed cell death ligand-1 (PD-L1) expression levels in tumors may help physicians understand which patients (pts) are most likely to respond to anti-PD-1/PD-L1 therapies in urothelial carcinoma (UC). Understanding the impact of different sample types and demographics on PD-L1 expression is important to determine suitability of tumor biopsies for testing.
Methods: As of July 24, 2016, 363 pts screened in the UC cohort of Study CD-ON-MEDI4736-1108 (NCT01693562) had tissue available for analysis and 47 pts had provided paired primary and metastatic samples. FFPE samples were tested in a central laboratory with the VENTANA PD-L1 (SP263) Assay using a BenchMark ULTRA instrument. Pts were classified as having either PD-L1 high (PD-L1 expression ≥25% either on tumour cells [TC] or immune cells [IC]) or PD-L1 low/negative (<25% on TC and IC) tumors. PD-L1 high prevalence was reported in primary vs metastatic sites, and by age, sex and race.
Results: PD-L1 status was evaluable for 332/363 (91.5%) pts (175/332 [52.7%] PD-L1 high and 157/332 [47.3%] PD-L1 low/negative) whose UC specimens were tested (intent to diagnose [ITD] population). Overall percentage agreement between paired primary and metastatic samples, based on combined TC/IC scoring ≥25%, was 74.5% (95% CI 59.7 - 86.1%). In the ITD population, using only the samples from which patient PD-L1 expression status was determined, PD-L1 high prevalence in primary and metastatic samples was 57.1% and 50.9% respectively (p=0.343, not significant). The proportion of pts with PD-L1 high status was not enriched in any demographic group (Table).
Conclusions: Initial data from UC pts in Study 1108 showed similar PD-L1 high prevalence in primary and metastatic lesions and good concordance between paired primary and metastatic samples. These results build optimism that samples obtained from either location could be used to determine PD-L1 status. Further data are needed to confirm these findings.

Associations between endogenous sex hormones and MRI structural changes in patients with symptomatic knee osteoarthritis. Osteoarthritis Cartilage 2017; 25:1100-1106.

Abstract
OBJECTIVE To investigate the longitudinal association between endogenous sex hormones and knee osteoarthritis (OA) structures and pain. METHOD We examined 200 participants (mean age 63.0 ± 7.3 years) from a clinical trial of vitamin D supplement for symptomatic knee OA. Serum levels of estradiol, progesterone, testosterone and sex hormone binding globulin (SHBG) were analyzed at baseline and 24 months later. Magnetic resonance imaging (MRI) scans of selected knee were obtained at both baseline and follow-up for the measurement of cartilage volume, cartilage defects, bone marrow lesions (BMLs) and effusion-synovitis volume. Knee pain was assessed using a 100 mm visual analogue scale (VAS). Longitudinal data were analyzed using linear mixed-effects model. RESULTS One hundred and seven males and 93 females were included in this study. For females, after adjustment for age, body mass index (BMI), and vitamin D level, progesterone was positively associated with cartilage volume (β = 0.12 mm3 per quartile, P < 0.01). Estradiol levels were associated with lower grades of BMLs (β = -0.46 per quartile, P = 0.03), while estradiol (β = -1.28 per quartile, P = 0.04), progesterone (β = -1.56 per quartile, P < 0.01) and testosterone (β = -1.51 per quartile, P = 0.01) were inversely associated with effusion-synovitis volume. Testosterone was inversely associated with knee pain. No consistent associations were observed for males. CONCLUSION In women but not men, low serum levels of endogenous estradiol, progesterone and testosterone are associated with increased knee effusion-synovitis and possibly other OA-related structural changes. This may contribute to observed sex differences in knee OA.

Abstract
OBJECTIVE To describe cross-sectional and longitudinal associations between magnetic resonance imaging (MRI)-detected osteophytes (OPs) and knee structural abnormalities and knee pain in older adults. METHOD A prospective population-based cohort study of 895 participants aged 50-80 years (mean age 62 years, 50% female) was performed. T1-or T2-weighted fat suppressed MRI was used to assess knee OPs, cartilage volume, cartilage defects and bone marrow lesions (BMLs) at baseline and after 2.6 years. Radiographically-detected OPs were scored according to the Osteoarthritis Research Society International (OARSI) atlas. Knee pain was assessed using a self-administered questionnaire at baseline, 2.6 and 5 years later. RESULTS 85% of participants had MRI-detected OPs at baseline, while 10% of participants had radiographically-detected OPs. Cross-sectionally, higher gardes of MRI-detected OPs in all compartments were significantly, independently and site-specifically associated with higher prevalences of cartilage defects and BMLs, lower cartilage volume and higher prevalence of knee pain. Longitudinally, higher gardes of baseline MRI-detected OPs site-specifically predicted greater risks of any increase in cartilage defects or BMLs, and loss of cartilage volume in medial and lateral tibiofemoral (LTF) and total compartments over 2.6 years in multivariable analyses. These significant associations were similar in those without radiographically-detected OPs. MTF and total OP scores were significantly associated with change in total knee pain over 2.6 and 5 years but these became non-significant after adjustment for cartilage defects and BMLs. CONCLUSION MRI-detected knee OPs are common and appear to be clinically relevant to knee structural changes in older adults.

Abstract
microRNA (miR)-590 has been found to serve potential roles in cancer development; however, the expression and function of miR-590 in human gliomas remains to be elucidated. The present study aimed to investigate the expression of miR-590 in human glioma tissues and radioresistant human glioblastoma cells (U251R), and to determine the effect and related molecular mechanism of miR-590-3p on the radiosensitivity of U251R cells in vitro. The results from reverse transcription-quantitative polymerase chain reaction indicated that miR-590-3p was upregulated in human glioma tissues and radioresistant human glioblastoma cells, and that miR-590-3p expression was higher in high grade than in low grade gliomas. In vitro experiments revealed that the miR-590-3p inhibitor enhanced the radiosensitivity of U251R cells by suppressing cell viability, decreasing colony formation capacity and increasing cell apoptosis rate, as demonstrated by MTT, colony formation and flow cytometry analyses. A luciferase reporter assay demonstrated that leucine-rich repeats and immunoglobulin-like domains protein 1 (LRIG1) was a direct target of miR-590-3p. Furthermore, it was demonstrated that the effect of miR-590-3p suppression on cell viability, colony formation capacity and cell apoptosis rate was attenuated by the knockdown of LRIG1 in the U251R cells. In conclusion, the present study revealed that miR-590-3p was upregulated in human glioma tissues and radioresistant human glioblastoma cells, and miR-590-3p contributes to the radioresistance of human glioblastoma cells by directly targeting LRIG1. These findings may provide potential therapeutic strategies to prevent radioresistance in human gliomas.

Abstract
PURPOSE We compared the clinical efficacy and toxicity of stereotactic body radiotherapy with induction chemotherapy and concurrent radiochemotherapy vs stereotactic body radiotherapy with subsequent chemotherapy in patients with clinical stage T1-3N0M0 non-small cell lung carcinoma. METHODS We retrospectively analyzed 38 patients with c-stage T1-3N0M0 non-small cell lung carcinoma who received stereotactic body radiotherapy. All patients received six cycles of chemotherapy. Fifteen of the patients were treated with three cycles of induction chemotherapy, one cycle of concurrent radiochemotherapy, and then two cycles of consolidation chemotherapy, while 23 patients received Sequential Radiotherapy/Chemotherapy. RESULTS Patients in the induction chemotherapy group experienced a longer duration of esophagitis (median 2 vs 0, range 0-6 vs 0-3.6 weeks, p = 0.04). We divided the patients into two groups based on their median pre-treatment tumor volume (cm3): >32.11 and ≤32.11. The tumor response rate in patients with larger tumor volume was substantially higher in the induction chemotherapy group than in the Sequential Radiotherapy/Chemotherapy group (66.67 vs 40%). Among patients with pre-treatment tumor volume (cm3) >32.11, the median local progression-free survival (LPFS) in the induction chemotherapy group and Sequential Radiotherapy/Chemotherapy group was 18 months (range 7-72 months) and 11 months (range 6-53 months), respectively. There was a statistically significant difference between the two groups (p = 0.006). CONCLUSIONS Simultaneous SBRT and chemotherapy can result in a longer duration of esophagitis. However, for patients with large tumor volume, ICT combined with concurrent radiochemotherapy may result in better local tumor response as well as longer LPFS and progression-free survival. To better elucidate the best treatment, further clinical trials are needed.

Abstract
OBJECTIVE To study the expression, roles, and clinical significance of Brahma (BRM) and matrix metalloproteinase 2 (MMP2) in the thoracic aortic aneurysm and aortic dissection. PATIENTS ND METHODS Arterial specimens from 20 cases of thoracic aortic dissection and 38 cases of thoracic aortic aneurysm, as well as normal tissue were collected, paraffin-embedded, sectioned, and stained with anti-BRM and MMP2 monoclonal antibodies. Sections were analyzed by immunofluorescence, and the distribution and expression of BRM and MMP2 in the aortic wall were determined. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to measure the expression of BRM and MMP2 mRNA in the thoracic aortic aneurysm, thoracic aortic dissection, and normal tissues. The expression of MMP2 and BRM protein in these tissues was analyzed by Western blot. SPSS 17.0 statistical software was used for data analysis. RESULTS MMP2 and BRM (mRNA and protein) were expressed in arterial tissue from thoracic aortic aneurysms and aortic dissections. Immunofluorescence also showed that BRM and MMP2 were expressed in the thoracic aortic aneurysm and aortic dissection tissue. The expression was very high in thoracic aortic aneurysm tissue. The differences in expression of BRM and MMP2 in the different arterial tissues were statistically significant (p<0.01). CONCLUSIONS Expression of BRM and MMP2 in the thoracic aortic aneurysm and aortic dissection is very high, indicating that BRM and MMP2 may play important roles in the occurrence and development of thoracic aortic aneurysm and aortic dissection. They may represent potential targets for the treatment of thoracic aortic aneurysm and aortic dissection and provide a new basis for clinical diagnosis.

Abstract
Objective: The purpose of the present study was to investigate the effects of noise competition on word perception in normal hearing (NH) children and children with cochlear implantation (CI). Methods: To estimate the contribution of noise competition on speech perception, word perception in speech-shaped noise(SSN)and 4-talker babble noise(BN) with Mandarin Lexical Neighborhood Test were performed in 80 NH children and 89 children with CI. Corrected perception percentages were acquired in each group. Results: Both signal to noise ratio (SNR) and noise type influenced the word perception. In NH group, corrected percentages of disyllabic word perception in SSN were 24.2%, 55.9%, 77.1%, 85.1% and 88.9% at -8, -4, 0, 4 and 8 dB SNR, corresponding corrected percentages of monosyllabic word were 13.9%, 39.5%, 60.1%, 68.8% and 80.1%, respectively. In BN noise, corrected percentages of disyllabic word were 2.4%, 24.3%, 55.6%, 74.3% and 86.2%, corresponding monosyllabic word were 2.3%, 20.8%, 47.2%, 61.1% and 74.8%, respectively. In CI group, corrected percentages of dissyllabic word in SSN and BN at 10 dB SNR were 65.5% and 58.1%, respectively. Corresponding monosyllabic word were 49.0% and 41.0%. For SNR=5 dB, corrected percentages of disyllabic word in SSN and BN were 50.0% and 38.1%, corresponding corrected percentages of monosyllabic word were 40.8% and 25.1%, respectively. Analysis indicated that the masking effect were significantly higher in BN compared with SSN. Conclusions: Noise competition influence word perception performance significantly. In specific, the influence of noise on word perception is bigger in children with CI than in NH children. The masking effect is higher in BN noise when compared with SSN.

Abstract
Objective: To construct the growth percentile curves of weight-, length/height-, head circumference and BMI for 1 to 4 year-olds who had been breastfed in urban areas. Methods: Data was from the longitudinal study on 1 025 breastfed children aged 1 to 4 years, in 8 urban areas during 2008-2012. MLwiN2.25 was selected to construct the multi-level models of weight-for-age,length for-age, head circumference-for-age and BMI-for-age. The models included many growth relevant factors including gender, age, family and social demographic characteristics, perinatal factors, parent biological characteristics, dietary patterns and diseases of childen. Based on these models, predicted values (P(3), P(15), P(50), P(85), P(97)) were estimated to fit the percentiles reference curves. Results: The percentiles reference curves of weight-, length/height, head circumferenceand BMI-for-age for the 1-4 year-olds who had been breastfed in the urban areas were developed. Differences of all the indicators between boys and girls were statistically significant (P<0.001). Weight, length/height, head circumference and BMI were higher in boys than those in girls, with an average differences as 0.56-0.76 kg, 0.89-1.12 cm, 0.64-0.91 cm and 0.31-0.52 kg/m(2). Conclusion: The percentiles reference curves on growth, constructed by the longitudinal observational data and scientific method, were important in reflecting the development of breastfed children in urban areas.

Abstract
Hepatocellular carcinoma (HCC) is one of the leading cause of cancer death in the world. Fructose-1,6-biphosphatase (FBP1), a rate-limiting enzyme in gluconeogenesis, has been identified recently as a tumor suppressor in HCC and other cancer types. In this study, we demonstrated that the tripartite motif-containing protein 28 (TRIM28) binds directly to and promotes FBP1 for ubiquitination and degradation. MAGE-A3 and MAGE-C2, which are known to be overexpressed in HCC, can enhance TRIM28-dependent degradation of FBP1 by forming ubiquitin ligase complexes with TRIM28. We further showed that expression of TRIM28 increased glucose consumption and lactate production by promoting FBP1 degradation in HCC cells and that FBP1 is a key mediator of TRIM28-induced HCC growth in culture and in mice. Moreover, we demonstrated that FBP1 and TRIM28 protein levels inversely correlated in HCC patient specimens. Finally, we showed that the proteasome inhibitor bortezomib mitigated the Warburg effect by inhibiting FBP1 degradation in HCC. Collectively, our findings not only identify oncogenic MAGE-TRIM28 complex-mediated proteasome degradation of FBP1 as a key mechanism underlying downregulation of FBP1 proteins in HCC, but also reveal that MAGE-TRIM28-regulated reprogramming of cancer cell metabolism and HCC tumorigenesis is mediated, at least in part, through FBP1 degradation.

Abstract
OBJECTIVE To describe cross-sectional and longitudinal associations between serum levels of interleukin (IL) - 6, IL-17A, IL-17F, IL-23 and knee bone marrow lesions (BMLs) in patients with knee osteoarthritis (OA). DESIGN Patients (n = 192) with symptomatic knee OA (mean 63 years, range 50-79, female 53%) were assessed at baseline and after 24 months. At each time point, serum IL-6, IL-17A, IL-17F and IL-23 were measured using Bio-Plex® Multiplex Immunoassays with Luminex xMAP technology. Knee BMLs were scored using the modified whole organ MRI score (WORMS) from T2 weighted fat-suppressed fast spin echo magnetic resonance imaging (MRI). Multivariable linear regression and log binominal regression were used to determine the associations between cytokines and BMLs. RESULTS Baseline IL-6 (quarters) were significantly associated with total knee BMLs (P < 0.01 for the trend) as well as associated with an increase in BML score (P = 0.05 for the trend), after adjustment for confounders. Baseline IL-17F and IL-23 (highest quarters vs others) was associated with an increase in BML score in females (P = 0.04 for IL-17F; P = 0.01 for IL-23), but not in males, in multivariable analyses. In contrast, IL-17A was not significantly associated with BMLs in either females or males. CONCLUSION IL-6 is associated with increased knee BMLs in both females and males with OA. Serum IL-17F and IL-23 predicted increased knee BML scores in females only, suggesting that inflammation is involved in BML pathogenesis in knee OA, especially in women.

Abstract
The magnetic characteristics of hemoglobin (Hb) changes with the binding of dioxygen (O2) to the heme prosthetic groups of the globin chains: from paramagnetic ferrous Hb to diamagnetic ferrous oxyhemoglobin (oxyHb) with reversibly bound O2, or paramagnetic ferric methemoglobin (metHb). When multiplied over the number of Hb molecules in a red blood cell (RBC), the effect is detectable through motion analysis of RBCs in a high magnetic field and gradient. This motion is referred to as magnetophoretic mobility, which can be conveniently expressed as a fraction of the cell sedimentation velocity. In this Article, using a previously developed and reported instrument, cell tracking velocimetry (CTV), we are able to detect difference in Hb concentration in two RBC populations to a resolution of 1 × 107 Hb molecules per cell (4 × 107 atoms of Fe per cell or 4-5 femtograms of Fe). Similar resolution achieved with inductively coupled plasma-mass spectrometry requires on the order of 105-106 cells and provides an average, whereas CTV provides a measurement for each cell. CTV analysis revealed that RBCs lose, on average, 17% of their Hb after 42 days of storage, the maximum FDA-approved length of time for the cold storage of RBCs in additive solution. This difference in Hb concentration was the result of routine RBC storage; clinical implications are discussed.

Abstract
BACKGROUND The present study aimed to discover more potential genes associated with the pathogenesis of asthma. METHODS The microarray data of GSE67940 was downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified in bronchial alveolar lavage cells from patients with mild-moderate asthma (notSA) and severe asthma (SA) compared with normal controls (NC), respectively. Functional and pathway enrichment analysis, protein-protein interaction (PPI) network analysis were performed upon the identified up- and down-regulated DEGs. Besides, the gene association network based on the common up-regulated and down-regulated genes was generated and transcriptional regulatory pairs of overlapping DEGs in the PPI network were identified. RESULTS A total of 104 DEGs (30 up- and 74 down-regulated genes) were identified in notSA vs. NC. Additionally, 2796 DEGs were screened out in SA vs. NC group, including 320 up-regulated DEGs, and 135 down-regulated DEGs. Specially, 41 overlapping DEGs were screened out in notSA vs. NC and SA vs. NC, including 16 common up-regulated genes and 25 common down-regulated genes. No pathways were enriched by the DEGs in notSA vs. NC. DEGs in SA vs. NC were associated with cytokine-cytokine receptor interaction. VEGFA was a hub protein in both the PPI networks of DEGs in notSA vs. NC and SA vs. NC. Gene association network showed that signalling pathways and cytokine-cytokine receptor interaction were involved in. The overlapping VEGFA, and IFRD1, and ZNF331 were regulated by more TFs. CONCLUSION Genes such as VEGFA, and IFRD1, and ZNF331 may be associated with pathogenesis of asthma.

Abstract
Abstract
Background: Neoadjuvant chemotherapy (NCT) is one of the main treatment strategies for patients with locally advanced breast cancer. This study was designed to demonstrate the utility of a platinum-containing treatment regimen in the neoadjuvant setting and to identify the predictive or prognostic value of Ki-67 among patients with triple-negative breast cancer (TNBC)
Methods: Data from 280 patients with stage II–III TNBC were collected. All patients underwent four cycles of NCT with paclitaxel (80 mg/m2) and carboplatin (AUC 2 mg*min/ml) on days 1, 8, and 15 of a 28-day cycle. Ki-67 values were evaluated in both biopsy and excision specimens. The clinical responses to NCT were evaluated based on MRI and ultrasound examinations in accordance with the response evaluation criteria in solid tumors (RECIST) version 1.1. The pathological evaluation of surgical specimens was conducted at by the Miller-Payne (MP) grading system. Logistic regression analysis was performed to identify independent predictors of pathological complete response (pCR). Survival analysis was performed to evaluate the prognostic value of various clinical and pathological variables.
Results: The overall pCR rate was 33.9%. Both the categorical and linear Ki-67 were independently correlated with pCR (P<0.001). There were also statistically significant differences among Ki-67 categories with respect to clinical response (P<0.001), Miller-Payne (MP) grades (P<0.001), and node status (P<0.001). A significant reduction of Ki-67 after NCT was most likely observed in patients with a relatively better response. Among 185 patients with a residual tumor after NCT, the tumor cell proliferation significantly decreased from a median Ki-67 value of 20.0% before chemotherapy to 15% after chemotherapy. The mean absolute reductions in Ki-67 were 29.4%, 8.5%, and -10.2% in patients with an ideal response (MP 5/4), a partial response (MP 3) and a poor response (MP2/1), respectively. In the multivariate model for non-pCR patients, Ki-67 reduction presented an independent prognostic value for relapse of disease (HR=0.986, 95% CI: 0.978-0.994; P=0.001). Residual node involvement was also an independent predictor of patient outcome (HR=0.895, 95% CI: 0.355-2.259 for 1-3 nodes and HR=2.424, 95% CI: 1.048-5.608 for more than 4 nodes, using 0 nodes as a reference; P=0.002). Better survival was more frequently observed in patients with a greater reduction in the Ki-67 value and fewer involved nodes.
Conclusions: The primary Ki-67 might help in further classifying TNBCs into subtypes with different responses to chemotherapy. The significant reduction of Ki-67 after treatment could indicate a favorable prognosis in non-pCR patients.
