Abstract
OBJECTIVE To explore the association between SPRY gene family and the risk of non-syndromic oral clefts among Chinese populations, in respect of single nucleotide polymorphisms (SNPs) association and parent-of-origin effects. METHODS Based on case-parent design, this study used the data of SPRY gene family in a next generation sequencing study of 183 non-syndromic cleft lip with or without cleft palate (NSCL/P) case-parent trios (549 participants) recruited from 2016 to 2018, to analyze the effects of SNP association and parent-of-origin. The sequencing study adopted a two-stage design. In the first stage, whole exome sequencing was conducted among 24 NSCL/P trios with family history to explore potential signals. Then in the second stage, another 159 NSCL/P trios were used as validation samples to verify the signals found in the first stage. The data of general information, disease features and parental environmental exposures for participants were collected through questionnaires. Blood samples were collected from each participant for DNA extraction and sequencing. Transmission disequilibrium tests (TDT) were conducted to test for the association between SNPs and NSCL/P, while Z score tests were applied to analyze parent-of-origin effects. The analyses were performed using Plink (v1.07). TRIO package in R (v3.5.1). Besides, famSKAT analyses were conducted in the first stage to combine the effect of SNPs located on the same gene, using famSKAT package in R(V3.5.1). Bonferroni method was adopted to correct multiple tests in the second stage. RESULTS Twenty-two SNPs in SPRY gene family were included for analyses after the quality control process in the first stage. Based on the variants annotation, functional prediction and statistical analysis, rs1298215244 (SPRY1) and rs504122 (SPRY2) were included in the second verification stage. TDTs in the verification stage revealed that rs1298215244: T>C, rs504122: G>C and rs504122: G>T were associated with the risk of NSCL/P after Bonferroni corrections, where rs504122: G>T was a rare variation. Although the test for parent-of-origin effect of rs1298215244: T>C reached nominal significance level, no SNP showed significant association with NSCL/P through parent-of-origin effect after Bonferroni corrections. CONCLUSION This study found that SNPs (including both common and rare variants) among the SPRY gene family were associated with the risk of NSCL/P among Chinese populations. This study failed to detect parent-of-origin effects among the SPRY gene family.

Abstract
Objective: Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common birth defect with its genetic evidence widely explored. This study explored the potential the parent-of-origin (PoO) effect of WNT pathway on the risks of NSCL/P, using a case-parent trio design. Methods: Data on the single nucleotide polymorphism (SNP) of WNT genes were selected from a genome-wide association study (GWAS). A total of 806 Chinese non-syndromic cleft lip patients, with or without cleft palate (NSCL/P) case-parent trios, were gathered from an international consortium. PoO effect of WNT pathway genes and its haplotypes were explored by log-linear models. Additional Wald tests were performed to assess: a) the heterogeneity of PoO effect between different maternal exposures, b) the interaction between PoO effect, c) maternal exposure to environmental tobacco smoke (ETS), and d) multivitamin supplementation during pregnancy. The threshold for statistical significance was adjusted as 3.47×10(-4), according to Bonferroni correction. Results: After quality control, a total of 144 SNPs within seven genes were included for analyses, among which 8 SNPs were of potential PoO effect (P<0.05). However, none of them achieved the statistical significance after Bonferroni correction. The haplotype rs4074668-rs12725747 (T-A) on WNT9A showed significant PoO effect, based on the haplotype test for PoO (P=2.74×10(-4)). In addition, no statistically significant interaction was found in further exploration of this haplotype under environmental exposures as ETS or multivitamin supplementation. Conclusions: Genes in the WNT pathway may influence the NSCL/P risks through the potential PoO effect. Particularly, the haplotype rs4074668-rs12725747 (T-A) on WNT9A presented significant PoO effect on NSCL/P, statistically. From this current study, findings on WNT pathway related risks among the NSCL/P, need to be further validated by independent samples in the future.

Abstract
Objective: To describe the study design, the characteristics of participants as well as the pedigrees included in the baseline survey of Fujian Tulou Family Cohort Study. Methods: Fujian Tulou Family Cohort Study was a prospective open cohort study with a biological sample bank. A baseline survey was conducted in Tulou areas of Nanjing county in Fujian province from 2015 to 2018, including questionnaire survey, physical and biochemical indicators examinations, and blood sample collection in adults aged ≥18 years. In addition, family relationship of the participants was also recorded. The pedigree information of the juveniles under 18 years old were also collected. Results: The baseline survey included 2 727 individuals in two clans, of whom 2 373 (87.0%) were adults, and 2 126 participants completed questionnaires, physical examinations and biochemical tests. The average age of the 2 126 participants was (57.9±13.3) years, with 39.4% being males. The current smoking rates in male and female participants were 41.2% and 2.1%, respectively. The corresponding rates of current alcohol consumption were 19.0% and 2.6%. For common chronic diseases, the prevalence rates were 51.3% for hypertension, 9.7% for diabetes and 26.7% for hyperlipemia according to the self-reported disease diagnoses, health examination results and biochemical examination results in class Ⅱ or Ⅲ hospitals. Based on the family relationship information and genealogical data, 710 pedigrees were finally identified, consisting of 5 087 family members. The numbers of five, four, three, and two generations pedigrees were 3, 88, 238 and 381, respectively. The pairs of the first to the fifth degree relatives were 12 039, 2 662, 1 511, 202 and 31, respectively. Conclusion: The establishment of Fujian Tulou Family Cohort provides valuable resources for exploring the genetic risk factors, environmental risk factors and gene-environment interactions contributing to the risk of common chronic diseases.

Abstract
Abstract
Background: Some forms of triple negative breast cancer (TNBC) rely on glutamine (Gln) metabolism for survival and growth (1), therefore, targeting this metabolic pathway provides a viable strategy for managing TNBC. Drugs that inhibit glutaminase (GLS), a key enzyme of glutaminolysis, are being developed (1,2). [18F]Fluciclovine is a PET imaging agent that enters/exits cells via glutamine transporters and undergoes minimal metabolism. Therefore, we hypothesize, that akin to our prior work with [18F]fluoroglutamine (3), the distribution volume (VT) of fluciclovine obtained from dynamic PET can be used to estimate the cellular glutamine level (pool size) and to mark the effect of pharmacological inhibitors of tumor glutaminase (GLS). We tested this hypothesis in human TNBC and ER+ breast cancer xenograft exhibiting a high and low GLS activity, respectively.
Methods: To make [18F]fluciclovine preparation suitable for mouse imaging, citrate in the formulation was removed and replaced with PBS by eluting through a column (Bio-Rad). Cellular uptake was performed in the presence and absence of Gln transporter inhibitors and GLS inhibitor. In vivo dynamic PET imaging were performed on mice bearing HCC1806 (TNBC) and MCF-7 (ER+ BC) xenografts. Dynamic PET images were analyzed by Logan Plot (PMOD) to estimate VT.
Results: Cellular uptake of [18F]fluciclovine in HCC1806 and MCF-7 cells were sensitively inhibited by cold glutamine (Gln) and GPNA (a pharmacologic inhibitor of ASCT-2), confirming that the uptake is mediated by Gln transporters. The peak uptake in MCF-7 cells was 5-fold higher than HCC1806. In mouse models, VT from in vivo [18F]Fluciclovine PET in MCF-7 tumor is 1.4-fold of HCC1806. These data are consistent with a higher cellular Gln pool size in MCF-7 as the result of its lower GLS activity. After inhibition of tumor GLS activity, VT of [18F]fluciclovine in HCC-1806 tumors was increased by 56% from baseline values (n=2), whereas VT in MCF-7 tumors decreased 1% after treatment (n=2). Only a small change of FDG PET signal (5% decrease, n=5) was detected in TNBC tumors after GLS inhibitor treatment.
Discussions: These data suggest that VT obtained from [18F]fluciclovine PET is sensitive to changes of the Gln pool size induced by GLS inhibition whereas FDG PET is not. Since the Gln pool size is inversely related to the GLS activity, increased VT is consistent with the increased intracellular Gln level when metabolic conversion of Gln to glutamate by GLS is inhibited. Our results suggest that [18F]fluciclovine, an imaging agent approved for prostate cancer imaging, may be useful for assessing glutamine pool size in breast cancer and changes in response to GLS inhibition

Abstract
Objective: To explore the association between gestational weight gain (GWG) and adverse pregnancy outcomes. Methods: A prospective study was conducted among 1 220 healthy singleton pregnant women in the first trimester of pregnancy, from Chengdu city, Sichuan province. Pre-gestational body mass and other basic information were collected through a set of questionnaires. Weight at the last week before delivery was measured and GWG was classified by IOM criteria (2009). Related information on pregnancy outcomes was collected after delivery, through the hospital information system. Multiple non-conditional logistic regression models were used to test the association between GWG and adverse pregnancy outcomes. Results: In total, data on 1 045 pregnant women were analyzed. Compared with adequate GWG, excessive GWG was associated with the increased risks of cord entanglement and large for gestational age (OR=1.641, 95%CI: 1.197-2.252; OR=1.678, 95%CI: 0.132-2.488), respectively. Additionally, when compared with the adequate GWG, insufficient GWG was associated with the increased risk of preterm delivery (OR=3.189, 95%CI: 1.604-6.341). Conclusions: Both excessive and insufficient GWG appeared associated with the pregnancy outcomes. Weight monitoring should be strengthened for pregnant women to reduce related risks on adverse pregnancy outcomes.

Abstract
Spinal networks in the cervical and lumbar cord are actively coupled during locomotion to coordinate arm and leg activity. The goals of this project were to investigate the intersegmental cervicolumbar connectivity during cycling after incomplete spinal cord injury (iSCI) and to assess the effect of rehabilitation training on improving reflex modulation mediated by cervicolumbar pathways. Two studies were conducted. In the first, 22 neurologically intact (NI) people and 10 people with chronic iSCI were recruited. The change in H-reflex amplitude in flexor carpi radialis (FCR) during leg cycling and H-reflex amplitude in soleus (SOL) during arm cycling were investigated. In the second study, two groups of participants with chronic iSCI underwent 12 wk of cycling training: one performed combined arm and leg cycling (A&L) and the other legs only cycling (Leg). The effect of training paradigm on the amplitude of the SOL H-reflex was assessed. Significant reduction in the amplitude of both FCR and SOL H-reflexes during dynamic cycling of the opposite limbs was found in NI participants but not in participants with iSCI. Nonetheless, there was a significant reduction in the SOL H-reflex during dynamic arm cycling in iSCI participants after training. Substantial improvements in SOL H-reflex properties were found in the A&L group after training. The results demonstrate that cervicolumbar modulation during rhythmic movements is disrupted in people with chronic iSCI; however, this modulation is restored after cycling training. Furthermore, involvement of the arms simultaneously with the legs during training may better regulate the leg spinal reflexes.NEW & NOTEWORTHY This work systematically demonstrates the disruptive effect of incomplete spinal cord injury on cervicolumbar coupling during rhythmic locomotor movements. It also shows that the impaired cervicolumbar coupling could be significantly restored after cycling training. Actively engaging the arms in rehabilitation paradigms for the improvement of walking substantially regulates the excitability of the lumbar spinal networks. The resulting regulation may be better than that obtained by interventions that focus on training of the legs only.

Abstract
Sorafenib (Sor) is clinical standard therapy for advanced hepatocellular carcinoma (HCC). However, detailed molecular mechanism behind Sor-exerted pharmacological effect remains unknown. In this study, sera samples, staged hepatic cancer tissues from Sor-treated patients with advanced HCC were harvested for a group of biochemical tests and immunoassays. Compared to non-treated control, blood contents of alanine transaminase (ALT), aspartate transaminase (AST), alphafetoprotein (AFP), fibroblast growth factor 21 (FGF21) were decreased in Sor-treated HCC patients, while the level of interleukin 10 (IL-10) were increased. As well, reduced triglyceride (TG), total cholesterol (T-CHOL), interferon gamma (IFN-γ), and tumor necrosis factor alpha (TNF-α) levels in sera were checked in Sor-treated HCC patients. In comparison with non-treated cancer sections, Sor-treated HCC cells showed decreased positive cells of proliferative marker for proliferating cell nuclear antigen (PCNA) and metastasized biomarker for cytokeratin 19 (CK19). In addition, elevated immunofluorescence-labeled cells of endoplasmic reticulum (ER)-stress markers of activating transcription factor 6 (ATF6), eukaryotic initiation factor 2α kinase (eIF2α), glucose-regulated protein (GRP-78), X-box binding protein 1 (XBP1) were observed in Sor-treated HCC livers. Further, validated data from Western blot assay exhibited that hepatocellular expressions of ATF6, eIF2α, GRP78, XBP1 in Sor-treated HCC liver cells were up-regulated. Briefly, our present clinicopathologic findings indicate that Sor-induced ER stress may be responsible for therapeutic mechanism against advanced HCC. In addition, induction of intracellular ER stress functions as a promising strategy for treating advanced HCC.

Abstract
We present a detailed study of the temperature (T) and magnetic field (H) dependence of the electronic density of states (DOS) at the Fermi level, as deduced from specific heat and Knight shift measurements in underdoped YBa_{2}Cu_{3}O_{y}. We find that the DOS becomes field independent above a characteristic field H_{DOS}, and that the H_{DOS}(T) line displays an unusual inflection near the onset of the long-range 3D charge-density wave order. The unusual S shape of H_{DOS}(T) is suggestive of two mutually exclusive orders that eventually establish a form of cooperation in order to coexist at low T. On theoretical grounds, such a collaboration could result from the stabilization of a pair-density wave state, which calls for further investigation in this region of the phase diagram.

Abstract
A magnetic order can be completely suppressed at zero temperature (T), by doping carriers or applying pressure, at a quantum critical point, around which physical properties change drastically. However, the situation is unclear for an electronic nematic order that breaks rotation symmetry. Here, we report nuclear magnetic resonance studies on NaFe_{1-x}Co_{x}As where magnetic and nematic transitions are well separated. The nuclear magnetic resonance spectrum is sensitive to inhomogeneous magnetic fields in the vortex state, which is related to London penetration depth λ_{L} that measures the electron mass m^{*}. We discovered two peaks in the doping dependence of λ_{L}^{2}(T∼0), one at x_{M}=0.027 where the spin-lattice relaxation rate shows quantum critical behavior, and another at x_{c}=0.032 around which the nematic transition temperature extrapolates to zero and the electrical resistivity shows a T-linear variation. Our results indicate that a nematic quantum critical point lies beneath the superconducting dome at x_{c} where m^{*} is enhanced. The impact of the nematic fluctuations on superconductivity is discussed.

Abstract
Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a common birth defect with a complex genetic architecture. Gene-gene interactions have been increasingly regarded as contributing to the etiology of NSCL/P. A recent genome-wide association study revealed that a novel single-nucleotide polymorphism at SPRY1 in 4q28.1 showed a significant association with NSCL/P. In the current study, we explored the role of 3 SPRY genes in the etiology of NSCL/P by detecting gene-gene interactions: SPRY1, SPRY2, and SPRY4-with SPRY3 excluded due to its special location on the X chromosome. We selected markers in 3 SPRY genes to test for gene-gene interactions using 1,908 case-parent trios recruited from an international consortium established for a genome-wide association study of nonsyndromic oral clefts. As the trios came from populations with different ancestries, subgroup analyses were conducted among Europeans and Asians. Cordell's method based on conditional logistic regression models was applied to test for potential gene-gene interactions via the statistical package TRIO in R software. Gene-gene interaction analyses yielded 10 pairs of SNPs in Europeans and 6 pairs in Asians that achieved significance after Bonferroni correction. The significant interactions were confirmed in the 10,000-permutation tests (empirical P = 0.003 for the most significant interaction). The study identified gene-gene interactions among SPRY genes among 1,908 NSCL/P trios, which revealed the importance of potential gene-gene interactions for understanding the genetic architecture of NSCL/P. The evidence of gene-gene interactions in this study also provided clues for future biological studies to further investigate the mechanism of how SPRY genes participate in the development of NSCL/P.

Abstract
The calibration-free laser-induced breakdown spectroscopy (CF-LIBS) and its variations are low cost, short time consumption, and high adaptability. However, seeking a more flexible and simple quantitative analysis method remains a challenge. A one-point and multi-line calibration (OP-MLC) was presented as a simple quantitative analysis method of LIBS. The results showed that OP-MLC-LIBS method can achieve quantitative analysis using only one standard sample, and the average relative errors (AREs) are 9, 22, 21 and 36% for Mn, Cr, Ni and Ti elements in six tested low-alloy steel samples, respectively. The method requires neither a large number of standard samples nor complicated calculations, which provides a flexible and low-cost quantitative analysis approach for development and application of LIBS.

Abstract
Objective: To assess the prevalence of visual impairment and the influencing factors among rural residents aged 60 years and above in Yugan county, Jiangxi province. Researchers analyzed influencing factors and provided scientific rationale for blindness prevention and control. Methods: Stratified cluster random sampling was used in randomly selecting 3 789 rural residents aged ≥ 60 in Yugan county. Eligible residents were invited to receive ophthalmic examinations and epidemiological investigations. Multivariate logistic regression was performed to analyze any influencing factors. Results: Three thousand seven hundred and eighty-nine rural residents completed the ophthalmic examination and investigation. Based on presenting visual acuity, the prevalence of visual impairment was 24.1%(915), of which blindness and moderate and severe was 2.9%(108) and 21.3%(807). The top five causes ranked are (1) cataract (283, 30.9%), (2) Refractive error (81, 8.9%), (3) macular degeneration (29, 3.2%), (4) Corneal opacity (14, 1.5%). Multivariate logistic regression showed that age, gender, education, occupation, marital status, ophthalmic anamnesis, smoking situation, and daily fruit intake were the main factors that were the influencing factors of visual impairment. Conclusions: The prevalence of visual impairment in the elderly population in rural areas of Yugan County is quite high. Keep a healthy diet, timely correction of eye disease, could reduce the risk of visual impairment. (Chin J Ophthalmol, 2018, 54:605-610).

Abstract
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound, the examiner and interpreter of the image are critical care medicine physicians. The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes. With the idea of critical care medicine as the soul, it can integrate the above information and clinical information, bedside real-time diagnosis and titration treatment, and evaluate the therapeutic effect so as to improve the outcome. CUS is a traditional technique which is applied as a new application method. The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept, implementation and application of CUS. It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure. At the same time, the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications, and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS. Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group, based on the rich experience of clinical practice in critical care and research, combined with the essence of CUS, to learn the traditional ultrasonic essence, established the clinical application technical specifications of CUS, including in five parts: basic view and relevant indicators to obtain in CUS; basic norms for viscera organ assessment and special assessment; standardized processes and systematic inspection programs; examples of CUS applications; CUS training and the application of qualification certification. The establishment of applied technology standard is helpful for standardized training and clinical correct implementation. It is helpful for clinical evaluation and correct guidance treatment, and is also helpful for quality control and continuous improvement of CUS application.

Abstract
The purpose of this work is to investigate the total resection of bladder tumor under transurethral fluorescence cystoscopy. Nineteen patients with bladder tumor, from which we resected a total of 26 tumors, including 16 single tumors with diameters of 0.5~2 cm, were enrolled in the study. All tumors were located in the posterior wall or neck of the bladder. For the surgery, the size and location of tumors in the bladder were observed by fluorescence cystoscopy. Then, plasma electrocision was used to cut the full-thickness of the bladder to the fat outside of the bladder along the near-end of the tumor, then along the left and right side of bladder (to the far-end), and the full-thickness of the tumor was resected. Finally, the far-end tumor was removed and the full-thickness of the bladder at the bottom was completely resected. All operations were completed successfully within 10-40 min. There was little bleeding during surgery and no secondary bleeding after surgery. Tumor staging found 17 patients at T1 stage (20 tumors) and 2 patients at T2 stage (6 tumors). Patients were followed up for 6~12 months without any recurrence. We show here that total resection of bladder tumor can be accomplished under transurethral fluorescence cystoscopy and preventative resection can be conducted on the suspicious bladder wall with precision to eliminate tumor residue that promotes recurrence.

Abstract
Background Increasing evidence has indicated an association between immune infiltration in gastric cancer and clinical outcome. However, reliable prognostic signatures, based on systematic assessments of the immune landscape inferred from bulk tumour transcriptomes, have not been established. The aim was to develop an immune signature, based on the cellular composition of the immune infiltrate inferred from bulk tumour transcriptomes, to improve the prognostic predictions of gastric cancer. Methods Twenty‐two types of immune cell fraction were estimated based on large public gastric cancer cohorts from the Gene Expression Omnibus using CIBERSORT. An immunoscore based on the fraction of immune cell types was then constructed using a least absolute shrinkage and selection operator (LASSO) Cox regression model. Results Using the LASSO model, an immunoscore was established consisting of 11 types of immune cell fraction. In the training cohort (490 patients), significant differences were found between high‐ and low‐immunoscore groups in overall survival across and within subpopulations with an identical TNM stage. Multivariable analysis revealed that the immunoscore was an independent prognostic factor (hazard ratio 1·92, 95 per cent c.i. 1·54 to 2·40). The prognostic value of the immunoscore was also confirmed in the validation (210) and entire (700) cohorts. Conclusion The proposed immunoscore represents a promising signature for estimating overall survival in patients with gastric cancer. Immunoscore predicts prognosis

Abstract
We report the status of an ongoing lattice-QCD calculation of form factors for exclusive semileptonic decays of B mesons with both charged currents (B → πlv, Bs → Klv) and neutral currents (B → πl+l-, B → Kl+l-). The results are important for constraining or revealing physics beyond the Standard Model. This work uses MILC’s (2+1 + 1)-flavor ensembles with the HISQ action for the sea and light valence quarks and the clover action in the Fermilab interpretation for the b quark. Simulations are carried out at three lattice spacings down to 0.088 fm, with both physical and unphysical sea-quark masses. We present preliminary results for correlation-function fits.

Abstract
Non-syndromic oral clefts (NSOC) are among the most common birth defects. The prevalence of NSOC is 1.13-1.30 per 1 000 live births in China, which is higher than those in other major ethnic groups. The etiology of NSOC is complex and heterogeneous, which involves both genetic and environmental risk factors. Although genome-wide association studies have identified a number of risk loci, these loci can only account for a small proportion of the heritability of NSOC. The next-generation sequencing research provides new ideas for further exploring the genetic risk factors of NSOC. This paper summaries the progress in the next-generation sequencing research of NSOC.

Abstract
Objective: To understand the association between gestational weight gain (GWG) per trimester/total (GWG) and gestational diabetes mellitus (GDM). Methods: A prospective cohort study was conducted among 829 healthy pregnant women from Chengdu who delivered a singleton during March-September 2013. Basic information about pre-pregnancy was collected at the first time, exercise information per trimester, dietary intake information per trimester and gestational age at delivery were obtained by questionnaire. Weight at the (12 ± 1)th, (28 ± 1)th, (36 ± 1)th and last week before delivery were measured. GDM was diagnosed according to the National Diabetes and Pregnancy Prevention Guidelines (2014). At last, a total of 682 pregnant women were analyzed. After controlling the potential confounders, multiple logistic regression models were used to test the associations between GWG per trimester/total GWG and GDM. Results: After adjusting for age at delivery, pre-pregnancy body mass index, family histories of type 2 diabetes and hypertension, exercise in the first trimester, parity and energy intake in trimester and other potential confounders. Compared with adequate GWG in the first trimester, insufficient and excessive GWG in the first trimester were associated with increased risk of GDM (OR=1.23, 95%CI: 0.63-2.38, and OR=2.20, 95%CI: 1.12-4.35). Compared with adequate GWG in the second trimester, insufficient and excessive GWG in the second trimester were associated with decreased risk of GDM (OR=0.47, 95%CI: 0.18-1.19, and OR=0.78, 95% CI: 0.43-1.42). Compared with adequate GWG in the third trimester, insufficient GWG in the third trimester was associated with increased risk of GDM (OR=1.48, 95%CI: 0.77-2.84), excessive GWG in the third trimester was associated with decreased risk of GDM (OR= 0.53, 95% CI: 0.28-0.99). Compared with adequate total GWG in pregnancy, insufficient GWG in pregnancy was associated with increased risk of GDM (OR=2.16, 95% CI: 1.04-4.46), excessive GWG in pregnancy was associated with decreased risk of GDM (OR=0.74, 95% CI: 0.38-1.46). Conclusions: Insufficient and excessive GWG in the first trimester were associated with increased risk of GDM, the first trimester may represent a critical period for risk of GDM. The effects of GWG in the second and third trimester on GDM need further study.

Abstract
The spinal cervico-lumbar interaction during rhythmic movements in humans has recently been studied; however, the role of arm movements in modulating the corticospinal drive to the legs is not well understood. The goals of this study were to investigate the effect of active rhythmic arm movements on the corticospinal drive to the legs (study 1) and assess the effect of simultaneous arm and leg training on the corticospinal pathway after incomplete spinal cord injury (iSCI) (study 2). In study 1, neurologically intact (NI) participants or participants with iSCI performed combinations of stationary and rhythmic cycling of the arms and legs while motor evoked potentials (MEPs) were recorded from the vastus lateralis (VL) muscle. In the NI group, arm cycling alone could facilitate the VL MEP amplitude, suggesting that dynamic arm movements strongly modulate the corticospinal pathway to the legs. No significant difference in VL MEP between conditions was found in participants with iSCI. In study 2, participants with iSCI underwent 12 wk of electrical stimulation-assisted cycling training: one group performed simultaneous arm and leg (A&L) cycling and the other legs-only cycling. MEPs in the tibialis anterior (TA) muscle were compared before and after training. After training, only the A&L group had a significantly larger TA MEP, suggesting increased excitability in the corticospinal pathway. The findings demonstrate the importance of arm movements in modulating the corticospinal drive to the legs and suggest that active engagement of the arms in lower limb rehabilitation may produce better neural regulation and restoration of function.NEW & NOTEWORTHY This study aimed to demonstrate the importance of arm movements in modulating the corticospinal drive to the legs. It provides direct evidence in humans that active movement of the arms could facilitate corticospinal transmission to the legs and, for the first time, shows that facilitation is absent after spinal cord injury. Active engagement of the arms in lower limb rehabilitation increased the excitability of the corticospinal pathway and may produce more effective improvement in leg function.

Abstract
We report the NMR observation of a skewed distribution of ^{17}O Knight shifts when a magnetic field quenches superconductivity and induces long-range charge-density-wave (CDW) order in YBa_{2}Cu_{3}O_{y}. This distribution is explained by an inhomogeneous pattern of the local density of states N(E_{F}) arising from quasiparticle scattering off, yet unidentified, defects in the CDW state. We argue that the effect is most likely related to the formation of quasiparticle bound states, as is known to occur, under specific circumstances, in some metals and superconductors (but not in the CDW state, in general, except for very few cases in 1D materials). These observations should provide insight into the microscopic nature of the CDW, especially regarding the reconstructed band structure and the sensitivity to disorder.

Abstract
AIMS To evaluate the sampling adequacy and diagnostic accuracy of the endometrial SAP-l sampling device in detecting endometrial lesions based on histopathological examination. MATERIALS AND METHODS In total, 182 patients who required an endometrial biopsy were enrolled in this study. All of the patients underwent endometrial biopsies with the SAP-l sampler prior to hysteroscopy (169/182) or dilatation and curettage (D&C) (13/182). Endometrial tissues were obtained at biopsy for histopathological examination. RESULTS Ad- equate endometrial specimens were obtained in 148 of 182 patients (81.32%). Menopause (p = 0.000), endometrial thickness (p = 0.004), and the types of endometrial diseases (p = 0.009) differed significantly between the two groups. Among the 169 patients who underwent hysteroscopy, sampling scratches were observed in the uterine cavity in 147 cases (86.98%). Compared to traditional methods, such as hysteroscopy and D&C, the sampling diagnostic sensitivity, specificity, and positive and negative predictive values were 82.35%, 100%, 100% , and 97.76% for endometrial carcinoma (n=17) and 37.5%, 100%, 100% and 97.76% for endometrial atypical hyperplasia (n=8), respectively. Those that were misdiagnosed occurred because the lesions were focal or localized in a small part of the uterine cavity. The sampling diagnostic sensitivity for polyps (n=32) was 12.5%. Two patients with submucosal leiomyoma went undiagnosed based on the sample specimens. CONCLUSION Endometrial sampling using the SAP-l sampler is a minimally invasive altemative technique for obtaining adequate endometrial specimens for histopathological examination. The SAP-l sampler was useful in detecting endometrial carcinoma and atypical hyperplasia cases that were not highly suspected to be localized; however, this method was not useful in detecting endometrial polyps and submucosal leiomyomas.

Abstract
Phase II of seed imbibition is a critical process during seed priming. To identify genes involved in rice seed priming, the altered proteins between the dry and imbibed (24 h) seeds were compared using a two-dimensional gel electrophoresis system in this study. Ten significantly changed proteins (fold change ≥ twofold; P < 0.01) were successfully identified, which could be categorised as carbohydrate and protein biosynthesis and metabolism-related, signalling-related, storage and stress-related proteins. A meta-analysis indicated that the highest expression of the identified genes was at the milk and dough stages and in the endosperm tissue. Quantitative real-time PCR analysis showed that there was significant variation in gene expression (except FAD-dependent oxidoreductase) in embryos during seed priming (0-48 h). The expression of genes associated with stress appeared at the early imbibition stage, while those associated with carbohydrate metabolism, protein synthesis and signalling increased at the late imbibition stage. Three identified proteins (glucose-1-phosphate adenylyltransferase large subunit, aminotransferase and prolamin precursor) had similar transcript and protein expression patterns in embryos. Based on phenotype and gene expression, the optimal stop time for seed priming is 24 h, when these three genes have relatively low expression, followed by significant induction during imbibition in embryos. These three genes are ideal candidate biomarkers for rice seed priming.

Abstract
Objective: To prepare a rabbit monoclonal antibody GCET2 and to investigate its diagnostic value in the workup of diffuse large B-cell lymphoma (DLBCL). Methods: GCET2 rabbit monoclonal antibody was developed by using RabMAb® technology, and its specificity was confirmed by ELISA, Western blot, immunohistochemistry (IHC) and flow cytometry. A panel of immunomarkers including GCET2, CD10, bcl-6, MUM1, GCET1, FOXP1, Ki-67 and CMYC was evaluated in 81 cases of DLBCLs, 5 cases of follicular lymphomas (FL) and 2 cases of Burkitt's lymphomas. Results: Rabbit monoclonal GCET2 antibody (clone EP316) was developed with specificity for normal germinal center B-cells (GCB) and GCB origined lymphomas. In 81 cases of DLBCL, the positive rate of GCET2 was 43.2%(35/81), which was significantly higher than that of other germinal center markers. Moreover, among 81 DLBCLs, the proportions of high CMYC expression in GCET2 negative and positive groups were 15.2% (7/46) and 2.8% (1/35), respectively. Conclusion: GCET2 is a sensitive immunohistochemical marker for GCB derived lymphomas. Combined with other biomarkers, it may improve the diagnostic sensitivity of GCB-DLBCL.

Abstract
Objective: To analyze the clinical features of one case of spontaneous hemothorax caused by primary pleural chondrosarcoma and therefore to improve the understanding of this disease. Methods: The clinical features of a case with primary pleural chondrosarcoma were analyzed retrospectively and the related literatures were reviewed.The literature review was carried out with "primary pleural, chondrosarcoma" in Chinese and English respectively, as the search terms in Wanfang Data, CNKI and PubMed database from January 1980 to October 2015. A total of 6 articales, 1 in Chinese and 5 in English, were reviewed. Results: A 29 year-old male patient was admitted to the hospital because of fever, chest tightness, shortness of breath for 20 days. CT scan of the chest showed a mass near the right posterior fourth rib and right pleural effusion.Routine examination of the pleural effusion confirmed the presence of hemothorax. Thoracotomy was performed and revealed hemothorax in the right thorax, and a mass near the pleural apex. The tumor was removed by surgery and pleural decortication was also performed. Pathology study confirmed the diagnosis of high-differentiated chondrosarcoma. The patient was followed and there was no recurrence until now. A total of 6 case reports were retrieved from Wanfang Data, CNKI and PubMed. Five cases had complete data, including 2 males and 3 females(age from 28 to70), and another (a 78-year old male) without adequate data. Conclusions: Primary pleural chondrosarcoma is a rare disease, and hemothorax as the first manifestation is even rare. It is easily to be misdiagnosed due to nonspecific clinical symptoms.The final diagnosis depends ultimately on pathological biopsy. Thoracotomy is the most effective method for treatment of primary pleural chondrosarcoma.

Abstract
During development of the nervous system, molecular signals mediating cell-cell interactions play critical roles in the guidance of axonal growth and establishment of synaptic functions. The Eph family of tyrosine kinase receptors and their ephrin ligands has been shown to mediate neuronal interactions in the development of topographic axon projection maps in several brain regions, and the loss of Eph activities result in defects in select axonal pathways. However, effects of deficiencies of the Eph signals on animal behavior have not been well documented. In this study, we showed that inactivation of a ligand of the Eph receptors, ephrin-A5, resulted in defects in maternal behavior and alterations in anxiety. Female ephrin-A5 -/- mice show significant defects in nest building and pup retrieval. In addition, lower levels of anxiety were observed in both male and female null mice. These changes were not due to deficiencies in estradiol, progesterone or corticosterone levels. Our observations suggest that ephrin-A5 plays a key role in the development and/or function of neural pathways mediating mouse maternal care and anxiety.

Abstract
OBJECTIVE To determine whether color doppler ultrasonography (CDU), thyroid function or thyroid autoimmune antibodies could identify Graves' disease in pregnancy(GDP) in pregnant patients with newly diagnosed thyrotoxicosis. METHODS It is an observational study. Sixty-eight pregnant patients with newly diagnosed thyrotoxicosis including gestational hyperthyroidism(GHT) subjects (GHT group, n=33) and GDP subjects (GDP group, n=35), and 62 age-and sex-matched healthy subjects (C1 group: pregnant, n=32, C2 group: non-pregnant, n=30) were recruited. Thyroid function, human chorionic gonadotropin(HCG), thyroid autoimmune antibodies were detected. Peak systolic velocity of the superior thyroid artery (STA-PSV) and diastole inner diameter(STA-D) of the superior thyroid artery were measured by CDU. A ROC curve was used to evaluate STA-PSV, STA-D, thyroid function and thyroid autoimmune antibodies for identification of GDP. RESULTS The area under the ROC curve of STA-PSV, STA-D and thyroid stimulating hormone (TSH), free T4 (FT4) for GDP were 0.905, 0.887, 0.803 and 0.786, respectively. The optimal cut-off points of STA-PSV, STA-D, TSH and FT4 for GDP were 40 cm/s, 2.0mm, 0.03 mIU/L and 30 pmol/L with the sensitivity of 82.9%, 72.1%, 81.8%, 76.2% and specificity of 81.8%, 87.9%, 75.2%, 80.3%, respectively. CONCLUSIONS Detection of STA-PSV and STA-D by CDU, as well as thyroid function, is useful in screening GDP in pregnant patients with thyrotoxicosis.

Abstract
The "classical" EAU model induced by immunization of mice with the retinal protein IRBP or its peptides has been very useful to study basic mechanisms of ocular inflammation, but is inadequate for some types of studies due to the need for active immunization in the context of strong bacterial adjuvants. We generated transgenic (Tg) mice on the B10.RIII background that express a T cell receptor (TCR) specific for IRBP161-180. Three strains of TCR Tg mice were established. Spontaneous uveitis developed in two of the three strains by 2-3 months of age. Susceptibility correlated with a higher copy number of the transgenic TCR and a higher proportion of TCR Tg T cells in the peripheral repertoire. Even in mice with uveitis, peripheral IRBP-specific CD4(+) T cells displayed mostly a naïve phenotype. In contrast, T cells infiltrating uveitic eyes mostly showed an effector/memory phenotype, and included Th1, Th17 as well as T regulatory cells. These mice thus provide a new and distinct model of uveitis from the "classical" EAU, and may represent some types of uveitis more faithfully. Importantly, this new transgenic model of uveitis can serve as a template for therapeutic manipulations, and as a source of naïve retina-specific T cells for a variety of basic and pre-clinical studies. Several examples of such studies will be discussed.

Abstract
The oncogene Lysosome-associated protein transmembrane-4β (LAPTM4B) gene was identified, and the polymorphism region in the 5′-UTR of this gene was certified to be associated with tumor susceptibility. LAPTM4B-35 protein was found to be highly expressed in various solid tumors and could be a poor prognosis marker. The functions of LAPTM4B in solid tumors were also explored. It is suggested that LAPTM4B could promote the proliferation of tumor cells, boost invasion and metastasis, resist apoptosis, initiate autophagy and assist drug resistance.

Abstract
To evaluate stearoyl-CoA desaturase (SCD), hormone-sensitive lipase (HSL), lipoprotein lipase (LPL), and peroxisome proliferator-activated receptor (PPARγ) expression in Lanzhou fat-tailed sheep (with and without docked tails), 18 rams were randomly divided into two equal groups (docked group, LT; control group, LC). These data were also used to increase the understanding of sheep fat deposition and metabolism. All animals were harvested at the age of 18 months, and expression was determined for 10 tissues. The results indicated that the fat weight of each tissue in LT was higher than in LC (P < 0.05). SCD expression in semitendinosus, omentum majus fat (OF), subcutaneous fat, kidney fat (KF), and subcutaneous rump fat was higher in LT than in LC rams (P < 0.05). Trends (P < 0.10) associated with higher HSL expression of LC in comparison to that of LT rams in intestinal fat, OF, and KF tissues were detected. Numerically, LPL expression was the highest in KF, OF, and kidney tissues, but there were few differences (P > 0.10). PPARγexpression was greater in LT than in LC rams in liver tissues (P < 0.05), but there were few differences in other tissues. No significant differences were found with regard to the regression analysis of expression and adipose tissue weights, but the two indices exhibited the same trend. The results indicated that changes in fatty deposits may be due to the common control of docking management and the minor effects associated with the regulation of SCD, HSL, LPL, and PPARγexpression.

Abstract
Abstract
Background: Breast cancer (BC) remains the second leading cause of cancer-related deaths for women in the United States and is recognized to be a heterogeneous disease. Advances in technologies such as whole genome sequencing are leading the way to precision medicine and the leading researchers are envisioning personalized therapies in the not too distant future. However, given the diversity of cancer cell populations, that remains a challenging task at best. The tumor form of MUC1 (designated tMUC1), a transmembrane glycoprotein, is aberrantly glycosylated and overexpressed in ∼95% of BC. We have developed an antibody (TAB004) that specifically recognizes tMUC1 across all major subtypes of BC and importantly does not recognize normal breast epithelia. This is a significant development in light of the challenges faced in treating triple negative BC.
Methods: A panel of thirty BC cell lines was obtained from ATCC. The following techniques were used to assess the specificity of TAB 004 to the major subtypes based on ER, PR and Her2 expression: 1) Flow cytometry to quantify membrane bound expression of tMUC1 using Cy7-conjugated TAB004; 2) Western blotting to detect molecular weight patterns of tMUC1 in whole cell lysate; 3) A TAB004 based GMP-grade ELISA kit to measure shed tMUC1 in the supernatant and 4) In vivo imaging of tumors in mice using TAB 004 conjugated to Indocyanine Green (ICG). Specificity and sensitivity was further confirmed using primary human serum and tissue samples from all major BC subtypes obtained from bio-repositories at Duke University Cancer Center, Fox Chase Cancer Center and Carolinas Health Care System. Shed tMUC1 in serum samples were tested using the TAB 004 ELISA kit and tissue sections were analyzed using immunohistochemical (IHC) staining with TAB 004 conjugated to HRP.
Results: 1) Flow cytometry data shows that TAB 004 recognized tMUC1 on all major BC subtypes: 25 out of 30 BC cell lines tested had higher expression than a normal epithelial breast cell line; 2) Western blotting also detected tMUC1 on all BC subtypes with distinct molecular weight patterns; 3) ELISA showed high levels of shed tMUC1 by most BC cells and correlated with bound/cytoplasmic levels. 4) In vivo imaging shows clear localization of TAB004-ICG to the tumors expressing tMUC1. Primary human breast cancer patient data shows that shed tMUC1 was detected in the serum obtained from all major BC subtypes and showed statistically significant differentiation from normal/benign. IHC results show strong tMUC1 expression in malignant tissue with excellent differentiation from adjacent normal tissue.
Conclusion: TAB004 antibody's extraordinary specificity across major BC subtypes has been confirmed with flow cytometry, western blotting, ELISA and Immunohistochemistry. A number of clinical applications are under development: (a) An ELISA test as a supplement to mammography for the early detection of BC in women with dense breasts; (b) serum monitoring during treatment and to detect disease recurrence; and, (c) targeted antibody-drug/antibody-imaging agent based therapies and imaging modalities particularly for triple negative BC.

Abstract
Pd/CeO2-ZrO2-Nd2O3 (CZN) catalysts with different CeO2/ZrO2 molar ratios were synthesized and have been characterized by multiple techniques, e.g. XRD in combination with Rietveld refinement, UV-Raman, XPS and in situ DRIFTS. The XRD pattern of CZN with CeO2/ZrO2 molar ratios ≥1/2 can be indexed satisfactorily to the fluorite structure with a space group Fm3̄m, while the XRD patterns of CZ12 only display diffraction peaks of the tetragonal phase (S.G. P42/nmc). Nd addition can effectively stabilize the cubic structure of the CZN support and increase the enrichment of defect sites on the surface, which may be related to the better catalytic activity of Pd/CZN12 catalysts compared with Pd/CZ12. The presence of moderate ZrO2 can increase the concentration of O* active species, leading to accelerate the formation of nitrate species and thus enhance the catalytic activity of NOx and HC elimination. The Pd-dispersion decreases with the increasing Zr content, leading to the decreased CO catalytic activity, especially for the aged catalysts. The change regularity of the OSC value is almost the same with the in situ dynamic operational window, demonstrating that the in situ dynamic operational window is basically affected by the OSC value.
