Abstract
A new generation of millimeter-wave heterodyne imaging receiver arrays has been developed and demonstrated on the DIII-D electron cyclotron emission imaging (ECEI) system. Improved circuit integration, improved noise performance, and enhanced shielding from out-of-band emission are made possible by using advanced liquid crystal polymer (LCP) substrates and monolithic microwave integrated circuit (MMIC) receiver chips. This array exhibits ∼15 dB additional gain and >30× reduction in noise temperature compared to previous generation ECEI arrays. Each LCP horn-waveguide module houses a 3 × 3 mm GaAs MMIC receiver chip, which consists of a low noise millimeter-wave preamplifier, balanced mixer, and IF amplifier together with a local oscillator multiplier chain driven at ∼12 GHz. A proof-of-principle partial LCP instrument with 5 poloidal channels was installed on DIII-D in 2017, with a full proof-of-principle system (20 poloidal × 8 radial channels) installed and commissioned in early 2018. The enhanced shielding of the LCP modules is seen to greatly reduce the sensitivity of ECEI signals to out-of-band microwave noise which has plagued previous ECEI studies on DIII-D. The LCP ECEI system is expected to be a valuable diagnostic tool for pedestal region measurements, focusing particularly on electron temperature evolution during edge localized mode bursting.

Abstract
Synthetic diagnostics are aimed at simulating the response of diagnostic systems under actual experimental scenarios and are the key to drawing quantitative inferences from experimental data. The synthetic Electron Cyclotron Emission Imaging (ECEI) diagnostic is suitable for evaluation of the improvement arising from the application of Field Curvature Adjustment (FCA) lenses in the design of the upgraded Experimental Advanced Superconducting Tokamak (EAST) tokamak ECEI system. In previous ECEI systems, a curved image plane is inevitable in optics systems comprising only convex lenses, which leads to significant crosstalk between vertically adjacent channels and strongly limits the vertical channel resolution of the imaging system. The synthetic ECEI diagnostic results show that, with FCA lenses applied, the upgraded ECEI system has significant advantages to focus on high poloidal wavenumber structures with the aberrations from the spherical surfaces corrected and the various artifacts related to the field curvature suppressed. Also, the synthetic ECEI diagnostic is used for some quantitative calculations to partially decouple the effect of density fluctuations and temperature fluctuations for a given plasma.

Abstract
1. Enhancing bone strength to solve leg disorders in poultry has become an important goal in broiler production. Bone morphogenetic protein 7 (BMP7), a member of the BMP family, represents an attractive therapeutic target for bone regeneration in humans and plays critical roles in skeletal development. 2. The objective of this study was to investigate the relationship between BMP7 gene expression, single-nucleotide polymorphisms (SNPs) and growth traits in chickens. Here, a SNP (c.1995T>C) in the chicken (Gallus gallus) BMP7 gene was identified, that was associated with growth and carcass traits. 3. Genotyping revealed that the T allele occurred more frequently in breeds with high growth rates, whereas the C allele was predominant in those with low growth rates. The expression level of BMP7 in the thigh bone of birds with the TT genotype was significantly higher than in those with the CC genotype at 21, 42 and 91 d of age. 4. These findings suggest that selecting the birds with the TT genotype of SNP c.1995T>C could improve bone growth, could reduce leg disorders in fast-growing birds. The SNP c.1995T>C may serve as a selective marker for improving bone growth and increasing the consistency of body weights in poultry breeding.

Abstract
OBJECTIVE To compare the safety and treatment effectiveness of retroperitoneal laparoscopic tumor aspiration and laparoscopic partial nephrectomy (LPN) in the treatment of renal angiomyolipoma (RAML). METHODS We retrospectively reviewed the clinical data of patients with pathologically confirmed RAML who received operation between August 2010 and August 2016 in the Department of Urology, Peking University First Hospital. Among them, a series of 121 patients were included in this trial according to the inclusion criteria, of which 74 cases could be collected and followed-up effectively. Based on the detailed surgical route, the 74 patients were divided into groups A and B: group A, which underwent retroperitoneal laparoscopic tumor aspiration, included 43 cases; group B, which received retroperitoneal LPN, included 31 cases. Patient demographics, intraoperative variables and postoperative outcomes were reported and compared between the groups. RESULTS No statistical difference was detected in both groups before the treatment. Intraoperatively, the mean estimated blood loss was 48.7 mL in group A and 102.9 mL in group B, and the mean operative time was 70.1 min (21.2 min of warm ischemia time included) in group A and 103.6 min (28.5 min of warm ischemia time included) in group B, which were both statistically different. In group A, no complications occurred and yet 2 complications of transfusion and 1 complication of urine leakage were discovered in group B, although all finally recovered only with conservative treatment. A statistical difference was observed in the complication rates. Post-operatively, the mean serum creatinine level was 1.13 mg/dL in group A, and the level was 1.08 mg/dL in group B, in which no evident difference was detected. In a mean 52.6-months' follow-up, a recurrence of 3 cases in group A (7.0%) and a recurrence of 2 cases in group B (6.5%) were reported. No evident difference was also detected between the groups in the tumor recurrence rates. CONCLUSION Due to the improvements in the intraoperative blood loss and operative time, retroperitoneal laparoscopic tumor aspiration may be provided with more potential advantages in the safety, also with equal efficacy of lower tumor recurrence rates when compared with the traditional retroperitoneal LPN in the treatment of RAML.

Abstract
BACKGROUND Copy Number Variations (CNVs) are an important genetic cause of a number of neurodevelopmental disorders (NDs). However, the association between CNVs and the development and prognosis of fetal isolated mild ventriculomegaly (IMV) is unclear. OBJECTIVES To investigate possible associations between CNVs and the development of fetal IMV. METHODS This retrospective study recruited 154 subjects with ultrasound-confirmed fetal IMV and 190 subjects in a control cohort who underwent a high-risk prenatal serum screening program. The exclusion criteria included fetus G-banding chromosomal abnormality or positive fetus TORCH infection. DNA samples from all 344 fetuses were examined by an SNP-array. Developmental outcomes were assessed during postnatal follow-up. RESULTS Fourteen pathogenic CNVs (pCNVs) were identified in 13 out of 154 IMV fetuses. Three pCNVs were found in 3 out of 190 subjects in the prenatal screening high-risk cohort, with a significant difference (P value=0.016, X2 test). Notably, the 14 pCNVs detected in the IMV cohort were all associated with neurodevelopmental disorders (NDs), including autism, intellectual disability. Among the 13 IMV fetuses carrying pCNVs, five subjects were found in the postnatal follow-up to manifest NDs, including two with autism and three with mild neurodevelopmental delay. The other 8 subjects consisted of three normal infants younger than 12-months old, two lost in the follow-up, and three with the termination of pregnancy. Out of 141 IMV subjects without detectable pCNVs, 123 subjects showed normal development, 16 were lost in the follow-up, 2 subjects terminated the pregnancy due to fetal hydrocephalus or congenital heart disease in the late fetus development. CONCLUSIONS This study suggests an association between pCNVs and fetal IMV. pCNVs may be involved in the pathological process of fetal IMV and postnatal NDs. Identifying specific genomic alterations may provide an insight into pathogenetic mechanism and aid better diagnosis and prognosis of neurodevelopmental outcomes in fetal IMV.

Abstract
Objectives: To analyze and understand the risk factors related to HIV new infections among men who have sex with men (MSM). Methods: A longitudinal observational study among MSM was conducted to collect information on HIV related behaviors and sero-conversion. Univariate and multivariate generalized estimating equations (GEE) were used to discuss the risk factors for HIV new infection. Results: A total number of 4 305 MSM were followed during 2013-2015. Among those self-reported MSM who are seeking partners on the Interner tended to have higher proportion on receptive anal intercourse and consistent condom use during anal intercourse than the subgroups seeking their partners in gay bars or bathrooms. HIV incidence among followed MSM during the study period appeared as 4.3/100 person years, with adjusted RR (aRR) of HIV infection for receptive anal intercourse as group 2.20 (95% CI: 1.49-3.24) times than that of insertion anal intercourse group. Those who used rush-poppers (aRR=1.55, 95% CI: 1.10-2.17), unprotected anal intercourse (aRR=2.24, 95%CI: 1.62-3.08), and those with syphilis infection (aRR=2.95, 95%CI: 2.00-4.35) were also risk factors for HIV new infections. After controlling other factors, the relationship between the ways of seeking partners and HIV new infection was not statistical significant. Conclusion: Risk factors for HIV new infection among MSM appeared complex and interactive, suggesting that further studies are needed to generate tailored strategies for the prevention of HIV epidemic among MSM population.

Abstract
The purpose of this study was to investigate the functional connectivity (FC) of thalamic subdivisions in patients with juvenile myoclonic epilepsy (JME). Resting state functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) data were acquired from 22 JME and 25 healthy controls. We first divided the thalamus into eight subdivisions by performing independent component analysis on tracking fibers and clustering thalamus-related FC maps. We then analyzed abnormal FC in each subdivision in JME compared with healthy controls, and we investigated their associations with clinical features. Eight thalamic sub-regions identified in the current study showed unbalanced thalamic FC in JME: decreased FC with the superior frontal gyrus and enhanced FC with the supplementary motor area in the posterior thalamus increased thalamic FC with the salience network (SN) and reduced FC with the default mode network (DMN). Abnormalities in thalamo-prefrontocortical networks might be related to the propagation of generalized spikes with frontocentral predominance in JME, and the network connectivity differences with the SN and DMN might be implicated in emotional and cognitive defects in JME. JME was also associated with enhanced FC among thalamic sub-regions and with the basal ganglia and cerebellum, suggesting the regulatory role of subcortical nuclei and the cerebellum on the thalamo-cortical circuit. Additionally, increased FC with the pallidum was positive related with the duration of disease. The present study provides emerging evidence of FC to understand that specific thalamic subdivisions contribute to the abnormalities of thalamic-cortical networks in JME. Moreover, the posterior thalamus could play a crucial role in generalized epileptic activity in JME.

Abstract
The DNA methylation of imprinted genes is an important way to regulate epigenetic reprogramming of donor cells in somatic cell nuclear transfer (SCNT). However, the effects of sexual distinction on the DNA methylation of imprinted genes in cloned animals have seldom been reported. In this study, we analysed the DNA methylation status of three imprinted genes (Xist, IGF2 and H19) from liveborn cloned buffaloes (L group, three female and three male), stillborn cloned buffaloes (S group, three female and three male) and natural reproduction buffaloes (N group, three female and three male), using bisulphite sequencing polymerase chain reaction (BS-PCR). The expression levels of these imprinted genes were also investigated by quantitative real-time PCR (QRT-PCR). The DNA methylation levels of H19 were not significantly different among the groups. However, the Xist in female and IGF2 in male of the S group were found to be significantly hypomethylated in comparison with the same sexual buffaloes in L group and N group (p < .05). Furthermore, the expression levels of Xist, IGF2 and H19 in the stillborn female cloned buffaloes of S group were significantly higher than that of the female buffaloes in the L group and N group (p < .05). The expression levels of IGF2 and H19 in the stillborn male cloned buffaloes in the S group were significantly higher than that of the male buffaloes in the L group and N group (p < .05). These results indicate that Xist may be associated with the viability of female cloned buffaloes, and IGF2 may also be related to the viability of male cloned buffaloes.

Abstract
Objective: To study the clinical characteristics of Parkinson's disease (PD) patients with restless legs syndrome (RLS). Methods: Ninety-nine PD patients and eighty-nine control group were included into this study and assessed for RLS by the question 6 of the non-motor symptoms questionnaire (NMSquest). The PD patients were divided into the RLS group and non RLS group, according to their answers to the NMSquest.The severity of motor symptoms, anxiety, depression and quality of life were evaluated according Unified Parkinson Disease Rating Scale (UPDRS), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Parkinson' s Disease Quality Of Life Questionnaire(PDQ-39), respectively. Results: (1)18.2%(18/81)of the PD patients experienced RLS, the incidence was significantly higher than the general population (P<0.001). (2) The RLS patients were more often women (66.7% vs 33.3%, P=0.033 ). (3) The UPDRS-Ⅱ score(20±7, P=0.008), UPDRS-Ⅲ score(43±14, P=0.015), BDI score(23±13, P=0.002), BAI score(18±8, P=0.012), PDQ-39 score(75±26, P=0.000)in RLS group were significantly higher compared with non RLS group. (4) RLS showed no association with the course of the disease, the age, the PD onset age and levodopa dose equivalents. Conclusions: RLS more likely appears in PD patients, especially in women. The PD patients with RLS commonly suffer from serious motor symptom, low quality of life, anxiety and depression.

Abstract
Ischemic stroke can lead to loss of neurologic functions. It occurs due to obstruction in blood supply to the brain. It has been proposed that C807T(C/T) polymorphism within the platelet glycoprotein gene may be associated with density and function of glycoprotein Ia/IIa receptors and contributes to the pathogenesis of thrombotic disease. We assessed the association between C807T(C/T) and risk of ischemic stroke. Databases such as PubMed, Medline, Springer, Elsevier Science Direct, Cochrane Library, Google scholar, Wanfang Data (Chinese), and Chinese National Knowledge Infrastructure (CNKI, Chinese) were used to search for relevant studies. We found 16 eligible studies, which totaled to 4897 (case group 2340; control group 2557) participants. Overall, our results showed significant associations between C807T(C/T) polymorphism and risk of ischemic stroke based on T-allele comparisons (T vs C, pooled OR = 0.78, 95%CI = 0.68-0.90, P < 0.01), TT vs CC comparisons (pooled OR = 0.58, 95%CI = 0.42-0.81, P < 0.01), recessive models (TT vs TC + CC, pooled OR = 0.72, 95%CI = 0.59-0.87, P < 0.01) and dominant models (TT + TC vs CC, pooled OR = 0.70, 95%CI = 0.54-0.92, P < 0.05). There was no association in TC vs CC comparisons (pooled OR = 0.81, 95%CI = 0.63-1.04, P > 0.05). Subgroup analyses stratified according to Hardy-Weinberg equilibrium, sample size, and ethnicity also demonstrated significant associations between the two variables. Therefore, C807T(C/T) polymorphism in the platelet glycoprotein gene may be associated with susceptibility to ischemic stroke, and the T allele at this locus may decrease risk to ischemic stroke.

Abstract
BACKGROUND The present study investigated alteration of brain resting-state activity induced by antidepressant treatment and attempted to investigate whether treatment efficacy can be predicted at an early stage of pharmacological treatment. METHOD Forty-eight first-episode medication-free patients diagnosed with major depression received treatment with escitalopram. Resting-state functional magnetic resonance imaging was administered prior to treatment, 5 h after the first dose, during the course of pharmacological treatment (week 4) and at endpoint (week 8). Resting-state activity was evaluated in the course of the 8-week treatment and in relation to clinical improvement. RESULTS Escitalopram dynamically modified resting-state activity in depression during the treatment. After 5 h the antidepressant induced a significant decrease in the signal in the occipital cortex and an increase in the dorsolateral and dorsomedial prefrontal cortices and middle cingulate cortex. Furthermore, while remitters demonstrated more obvious changes following treatment, these were more modest in non-responders suggesting possible tonic and dynamic differences in the serotonergic system. Changes after 5 h in the caudate, occipital and temporal cortices were the best predictor of clinical remission at endpoint. CONCLUSIONS This study revealed the possibility of using the measurement of resting-state neural changes a few hours after acute administration of antidepressant to identify individuals likely to remit after a few weeks of treatment.

Abstract
Objective: To investigate the changes in protein expression in patients with 1-bromopropane (1-BP) poisoning using high-throughput proteomic technique and to screen out protein markers. Methods: Serum samples were collected from 3 patients with 1-BP poisoning and 15 controls. The label-free proteomic tech-nique was used for the quantitation and identification of proteins expressed in these samples, and the results were compared between the patients with 1-BP poisoning and the control population. The bioinformatics tools were used to analyze the function of differentially expressed proteins. Results: Compared with the control popula-tion, the patients with 1-BP poisoning had >2-fold upregulation of 38 proteins and >2-fold downregulation of 68 proteins. The differentially expressed proteins were mainly involved in immune response, signal transduction, and stress response. Conclusion: The proteins screened out may be potential protein markers for 1-BP poison-ing, which provides reliable and precise methods and thoughts for the diagnosis of 1-BP poisoning.

Abstract
Millimeter-wave imaging diagnostics, with large poloidal span and wide radial range, have been developed on the EAST tokamak for visualization of 2D electron temperature and density fluctuations. A 384 channel (24 poloidal × 16 radial) Electron Cyclotron Emission Imaging (ECEI) system in F-band (90-140 GHz) was installed on the EAST tokamak in 2012 to provide 2D electron temperature fluctuation images with high spatial and temporal resolution. A co-located Microwave Imaging Reflectometry (MIR) will be installed for imaging of density fluctuations by December 2016. This "4th generation" MIR system has eight independent frequency illumination beams in W-band (75-110 GHz) driven by fast tuning synthesizers and active multipliers. Both of these advanced millimeter-wave imaging diagnostic systems have applied the latest techniques. A novel design philosophy "general optics structure" has been employed for the design of the ECEI and MIR receiver optics with large aperture. The extended radial and poloidal coverage of ECEI on EAST is made possible by innovations in the design of front-end optics. The front-end optical structures of the two imaging diagnostics, ECEI and MIR, have been integrated into a compact system, including the ECEI receiver and MIR transmitter and receiver. Two imaging systems share the same mid-plane port for simultaneous, co-located 2D fluctuation measurements of electron density and temperature. An intelligent remote-control is utilized in the MIR electronics systems to maintain focusing at the desired radial region even with density variations by remotely tuning the probe frequencies in about 200 μs. A similar intelligent technique has also been applied on the ECEI IF system, with remote configuration of the attenuations for each channel.
