Abstract
OBJECTIVE To evaluate the clinical value of ultrasound findings in the screening of fetal chromosomal abnormalities and the analysis of risk factors for chromosome microarray analysis (CMA) abnormalities. METHODS We retrospectively analyzed the datasets of 15,899 pregnant women who underwent prenatal evaluations at Affiliated Maternity and Child Health Care Hospital of Nantong University between August 2018 and December 2022. Everyone underwent ultrasound screening, and those with abnormal findings underwent CMA to identify chromosomal abnormalities. RESULTS The detection rates for isolated ultrasound anomalies and combined ultrasound and CMA anomalies were 11.81% (1877/15,899) and 2.40% (381/15,899), respectively. Among all ultrasound abnormalities, detection rates for isolated ultrasound soft marker anomalies, isolated structural abnormalities, and both ultrasound soft marker anomalies with structural abnormalities were 82.91% (1872/2258), 15.99% (361/2258), and 1.11% (25/2258), respectively. The detection rate of abnormal chromosomes in pregnant women with abnormal ultrasound results was 16.87% (381/2258). The detection rates were 13.33% in cases with two or more ultrasound soft markers anomalies, 47.37% for two or more structural anomalies, and 48.00% for concomitant ultrasound soft marker and structural anomalies. CONCLUSIONS Enhanced detection rates of chromosomal anomalies in fetal malformations are achieved with specific ultrasound findings (NT thickening, cardiovascular abnormalities, and multiple soft markers) or when combined with high-risk factors (advanced maternal age, familial history, parental chromosomal anomalies, etc.). When the maternal age is over 35 and with ≥2 ultrasound soft marker anomalies accompanied with any high-risk factors, CMA testing can aid in the diagnosis of prenatal chromosomal abnormalities.

Abstract
Primary microcephaly is characterized by a head circumference prenatally or at birth that falls below three standard deviations from age-, ethnic-, and sex-specific norms. Genetic defects are one of the underlying causes of primary microcephaly. Since 2014, five variants of the SASS6 gene have been identified as the cause of MCPH 14 in three reported families. In this study, we present the genetic findings of members of a nonconsanguineous Chinese couple with a history of microcephaly and fetal growth restriction (FGR) during their first pregnancy. Utilizing trio whole-exome sequencing, we identified compound heterozygous variants involving a frameshift NM_194292.3:c.450_453del p.(Lys150AsnfsTer7) variant and a splice region NM_194292.3:c.1674+3A>G variant within the SASS6 gene in the affected fetus. Moreover, reverse transcriptase-polymerase chain reaction from RNA of the mother's peripheral blood leukocytes revealed that the c.1674+3A>G variant led to the skipping of exon 14 and an inframe deletion. To the best of our knowledge, the association between FGR and SASS6-related microcephaly has not been reported, and our findings confirm the pivotal role of SASS6 in microcephaly pathogenesis and reveal an expanded view of the phenotype and mutation spectrum associated with this gene.

Abstract
Metabolic diseases and their complications impose health and economic burdens worldwide. Evidence from past experimental studies and clinical trials suggests our body may have the ability to remember the past metabolic environment, such as hyperglycemia or hyperlipidemia, thus leading to chronic inflammatory disorders and other diseases even after the elimination of these metabolic environments. The long-term effects of that aberrant metabolism on the body have been summarized as metabolic memory and are found to assume a crucial role in states of health and disease. Multiple molecular mechanisms collectively participate in metabolic memory management, resulting in different cellular alterations as well as tissue and organ dysfunctions, culminating in disease progression and even affecting offspring. The elucidation and expansion of the concept of metabolic memory provides more comprehensive insight into pathogenic mechanisms underlying metabolic diseases and complications and promises to be a new target in disease detection and management. Here, we retrace the history of relevant research on metabolic memory and summarize its salient characteristics. We provide a detailed discussion of the mechanisms by which metabolic memory may be involved in disease development at molecular, cellular, and organ levels, with emphasis on the impact of epigenetic modulations. Finally, we present some of the pivotal findings arguing in favor of targeting metabolic memory to develop therapeutic strategies for metabolic diseases and provide the latest reflections on the consequences of metabolic memory as well as their implications for human health and diseases.

Abstract
The synthetic aperture infrared radio imaging method based on laser local oscillator coherent detection has potential application value for astronomical observations. This paper studies the multi-channel synthetic aperture infrared imaging method and conducts experimental verification using a principle prototype. In the short-wave infrared band, five beam-expanding fiber collimators are used to build an observation structure of five laser local oscillator coherent detection channels at a near-field distance of 5 m to carry out physical experiments. The laser local oscillator wavelength is 1.55 µm, and the AD sampling rate is 4 GHz. For the infrared radiation source signal, the phase relationship of the infrared signals between channels acquired by the prototype principle is stable, and the five-channel synthetic aperture imaging results are consistent with the computer simulated results. The experiment verified the effectiveness of the laser local oscillator comprehensive aperture infrared radio imaging method.

Abstract
Diabetes mellitus (DM) is a chronic age-related disease that was recently found as a secondary aging pattern regulated by the senescence associated secretory phenotype (SASP). The purpose of this study is to detect the potential efficacy and the specific mechanisms of low-level laser therapy (LLLT) healing of age-related inflammation (known as inflammaging) in diabetic periodontitis. Diabetic periodontitis (DP) mice were established by intraperitoneal streptozotocin (STZ) injection and oral P. gingivalis inoculation. Low-level laser irradiation (810 nm, 0.1 W, 398 mW/cm2, 4 J/cm2, 10 s) was applied locally around the periodontal lesions every 3 days for 2 consecutive weeks. Micro-CT and hematoxylin-eosin (HE) stain was analyzed for periodontal soft tissue and alveolar bone. Western blots, immunohistochemistry, and immunofluorescence staining were used to evaluate the protein expression changes on SASP and GLUT1/mTOR pathway. The expression of aging-related factors and SASP including tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 were reduced in periodontal tissue of diabetic mice. The inhibitory effect of LLLT on GLUT1/mTOR pathway was observed by detecting the related factors mTOR, p-mTOR, GLUT1, and PKM2. COX, an intracytoplasmic photoreceptor, is a key component of the anti-inflammatory effects of LLLT. After LLLT treatment a significant increase in COX was observed in macrophages in the periodontal lesion. Our findings suggest that LLLT may regulate chronic low-grade inflammation by modulating the GLUT1/mTOR senescence-related pathway, thereby offering a potential treatment for diabetic periodontal diseases.

Abstract
Cancer is one of the leading causes of human death worldwide. One of the most common types of malignancy among women is breast cancer, which is the third most common cancer in the world after lung and stomach cancer. This study aimed to evaluate the expression level of Tissue Differentiation-Inducing Non-Protein Coding RNA (TINCR) in adjacent tumor and non-tumor tissues of 60 women with invasive ductal breast cancer. The relationship between TINCR expression and the clinical characteristics of patients has also been studied. For this purpose, total RNA was isolated from breast cancer patients' adjacent tumor and non-tumor tissue. RT Prime Script reagent was then used to convert total RNA to cDNA. The qRT-PCR quantified the TINCR expression level and analyzed the results by paired t-test. In addition, ROC curve analysis was used to evaluate the biomarker power of TINCR in breast cancer tumor tissues. According to the results, a decrease in the level of TINCR was obtained in the tumor tissue of breast cancer patients compared to the adjacent non-tumor tissue (P<0.001). TINCR expression was negatively correlated with tumor size and lymph node metastasis in breast cancer tumor tissue. In general, the decrease in the expression level of TINCR in the tumor tissue of breast cancer patients shows that its expression level can differentiate the adjacent tumor and non-tumor tissue from each other. In addition, TINCR has a lower expression level in breast cancer patients with large tumors, lymph node metastasis, and luminal subgroups A and B.

Abstract
It was to investigate the value of quantitative fluorescence PCR (QF-PCR) for the selection of specific short tandem repeat (STR) in prenatal diagnosis of fetal chromosomal diseases. Amniotic fluid (AF) and villus samples were obtained from 80 pregnant women at 16-20 weeks of gestation, and venous blood samples were obtained from 60 normal individuals to extract and prepare peripheral blood chromosome, AF cell chromosome, and villus cell chromosome samples for specific STR locus detection. It showed that the area ratio of AMX peak to AMY peak in the Genescan typing map of peripheral blood DNA of normal males was close to 1:1, while the Genescan typing map of peripheral blood DNA of normal females had only AMX peak and no AMY peak. Normal heterozygous individuals had an area ratio between 1 and 1.45 for venous blood, 1.002 and 1.27 for villous samples, and 1 and 1.35 for AF samples. The karyotype of a male fetus was 46, XY, inv [9] (p11: q13), and the structure of fetal chromosome 9 was inverted (interarm), and the site of structural inversion was band 1 in the short breech 1 region and band 3 in the long arm 1 region of chromosome 9. It suggested that QF-PCR can effectively identify the normal human body and cases by selecting specific STR locus detection, which has a good application value for prenatal diagnosis of fetal chromosomal diseases.

Abstract
OBJECTIVE To explore the difference in parathyroid tissue-derived cells between male and female PHPT patients. METHODS Resected parathyroid tissues were collected from PHPT patients of both sexes. Single cells were isolated and sequenced for RNA expression profiles. The cell sequencing data were annotated by cell type, followed by population analysis, functional analysis, pathway analysis, cell communication analysis, differential gene expression analysis, and pseudotime trajectory analysis. The subcluster analyses were also performed in the parathyroid cells. RESULTS No substantial difference in the cell population, function, or communication is found between the two sexes. The interferon-a response, oxidative phosphorylation, and reactive oxygen species pathways are up-regulated in females than in male patients, mainly contributed by fibroblast cells, endothelial cells, parathyroid cells, and myeloid cells, which also have significantly more up-regulated pathways and cellular interactions than the other three cell types. The subcluster analysis of parathyroid cells identified five subpopulations: SPARCL1-OC and ISG15-OC are predominant in females, while more S100A13-PCC and PTHLH-OC are found in males. The cellular functions are also elevated in females compared with males. Cells from female patients show a higher expression level of parathyroid hormone (PTH) but a lower expression level of parathyroid hormone-like hormone (PTHLH). The cell pseudotime trajectory and pathway analyses show that the oxyphil cells may be more mature and functionally active than the chief cells in both sexes. CONCLUSION These findings suggest that the sex difference in PHPT may be caused by the differentially expressed genes and activated pathways in different cell types in the parathyroid tissue. The heterogeneity of parathyroid cell subpopulations, especially in oxyphil cells, may be associated with the sex differences in PHPT pathogenesis.

Abstract
BACKGROUND To measure total type 1 serum amino-terminal propeptide procollagen (t-P1NP), β- type 1 cross-linked C-terminal telopeptide collagen (β-CTX), N-terminal osteocalcin (OC), and 25-(OH)-VD3 levels before parathyroidectomy (PTX) in patients with PHPT, and correlate these measurements with bone mineral density (BMD) changes at 1-year post-PTX. METHODS Patients with primary hyperparathyroidism (PHPT) were followed from diagnosis to 12 months after surgery. Serum levels of calcium, parathyroid hormone (PTH), vitamin 25-(OH)-VD3, OC, β-CTX, t-P1NP, and BMD were measured before and 1 year after surgery. RESULTS One year after PTX, mean BMD increased by 25.7, 27.7, and 33.5% in the lumbar spine (L1-L4), femoral neck (FN), and greater trochanter (GT), respectively. Percent BMD change 1-year post-PTX was significant correlated with preoperative levels of β-CTX (L1-L4: r = 0.41, P < 0.0001; FN: r = 0.54, P = 0.0003; GT: r = 0.46, P = 0.0029), t-P1NP (L1-L4: r = 0.58, P < 0.0001; FN: r = 0.73, P < 0.0001; GT: r = 0.65, P < 0.0001), 25-(OH)-VD3 (L1-L4: r = -0.33, P = 0.034; FN: r = -0.48, P = 0.002; GT: r = -0.52, P = 0.0007), and OC (L1-L4: r = 0.49, P = 0.0013; FN: r = 0.55, P = 0.0002; GT: r = 0.47, P = 0.002). CONCLUSIONS Preoperative levels of turnover markers and BMD improvements were significantly correlated in patients with PHPT 1 year after PTX.

Abstract
Background:Underserved populations, such as ethnic minorities, low-income adults, and Indigenous people living with arthritis are more likely to have lower health literacy, higher rates of multi-morbidity, and face challenges in accessing care1-3. Self-management support (SMS) can help to mitigate the impacts of living with arthritis4. However, we require a more in-depth understanding of the daily barriers underserved communities face in living with arthritis in order to develop effective SMS that can meaningfully improve well-being and quality of life.Objectives:The study objective was to bring together underserved people living with arthritis to identify common barriers they face in taking care of their conditions in daily life, and to identify their solutions to the identified challenges.Methods:A team of researchers from several universities, nurse practitioners, physicians, policy makers, an arthritis consumer-patient leader and our community partners (Multi-lingual Orientation Service Association for Immigrant Communities and the Portland Hotel Society Community Services Society) engaged in a Community-based Participatory and Concept Mapping (CM) study5-7 where participants from underserved communities identified major barriers they face in managing arthritis, agreed on key themes that emerged, and determined priorities for actions. This involved three key CM activities: 1) brainstorming ideas; 2) sorting and rating ideas; and 3) analyzing and interpreting concept maps8. Data was collected through face-to-face interviews and prioritized and interpreted in workshop settings.Results:Sixty-three individuals who were ethnic minorities, immigrants, refugees, low-income, over 65, and/or housing insecure and living with arthritis identified 35 common barriers and made recommendations in the areas of financial difficulties, social services, access to health services, quality of health services, lack of knowledge, and mental health. Additional funding has been sought through Community-University Engagement Support Funding to enable our community partners to prioritize the recommendations in their communities, and to develop mechanisms for implementation using already existing community structures, processes, and services.Conclusion:Persons living with arthritis in diverse underserved communities face significant health and social inequities, including lack of access to basic life necessities such as food, housing, employment, and safety, which creates barriers to self-managing arthritis and other chronic conditions in daily life. SMS for these communities needs to address these social and environmental barriers shaping capacity for self-management, and ultimately, quality of life and well-being.References:[1]Ackerman I, Busija L.

Abstract
BACKGROUND Multiple pathological manifestations are rarely present in patients with primary hyperparathyroidism (PHPT). Here we described a case of a young woman who presented with multiple skeletal destructions and received an unclear diagnosis at several hospitals. CASE PRESENTATION A 30-year-old woman was admitted to our hospital due to pain in both knees and walking difficulty that lasted for 6 and 2 years, respectively. Her laboratory test results revealed a high parathyroid hormone level (822 pg/ml) and hypercalcemia (2.52 mmol/L) in the blood. Parathyroid imaging revealed a lumpy concentration of radioactive uptake detected at the lower pole in the right lobe of the thyroid, and was nearly 2.2 cm * 2.4 cm in size. Next, the patient was treated with parathyroidectomy that resulted in a significant improvement in physiological and clinical symptoms. Moreover, the skeletal destruction and bone mineral density were significantly improved after a 5-years follow-up period. CONCLUSIONS Multiple skeletal destructions can be caused by PHPT that should be taken into consideration in young patients with complex bone lesions.

Abstract
BACKGROUND The staging system for patients with anaplastic thyroid cancer (ATC) was updated in the 8th edition of the American Joint Committee on Cancer Staging Manual. A cut-off age of 55 years was stipulated as a prognostic factor for differentiated thyroid cancer; however, age was not considered for ATC patients. To this end, this study investigated the relationship between age at diagnosis and prognosis of ATC patients. METHODS The clinical information on ATC patients was acquired from the Surveillance, Epidemiology, and End Results Program public database. Youden's index and X-tile analyses were used to calculate the high-point age at diagnosis associated with prognosis. Cox proportional hazards models, Kaplan-Meier curves, and 1000-person-year were then used for verifying the accuracy of the high-point age. RESULTS After inclusion/exclusion criteria was applied, 586 patients were included in this study. The high-point age was determined to be 70 years by both the Youden's index and X-tile plot methods. The hazard ratio was 1.662 (95% confidence interval [CI]: 1.321-2.092), indicating that there was an increased risk of poor prognosis for patients > 70 years of age. The cancer-specific mortality rates per 1000-person-years for patients ≤ and > 70 years-old were 949.980 (95% CI: 827.323-1090.822) and 1546.667 (95% CI: 1333.114-1794.428), respectively. P-values were < 0.001 for the results shown above. CONCLUSION Our study found that age influenced the prognosis of ATC patients. Furthermore, we determined that the high-point age at diagnosis was 70 years and that > 70 years of age was associated with a poor prognosis. These results provide a useful addition to the staging manual and can improve the diagnosis, treatment strategies and prognosis of ATC patients.

Abstract
OBJECTIVE Primary hyperparathyroidism (PHPT) is relatively common in China and results in severe damage to the skeletal system. This study aimed to investigate changes in bone mineral density (BMD) over 2 years in patients with PHPT after parathyroidectomy. METHODS This retrospective cohort study included patients with PHPT who underwent parathyroidectomy between January 2010 and December 2015. BMD and T-scores and Z-scores of the lumbar spine (L1, L2, L3, and L4) and total hip (femoral neck, great trochanter, and Ward's triangle) at baseline and 2 years after surgery were measured by dual-energy X-ray absorptiometry. RESULTS Thirty patients with moderate to severe PHPT (17 men and 13 women) aged 38.90±15.48 years were included. BMD, and T-score and Z-score values at the lumbar spine and total hip at 6 months, 1 year, and 2 years after parathyroidectomy were significantly improved compared with preoperative values. Improvement in BMD was largest at L4 (46.7%) and smallest at L1 (37.4%) in the lumbar spine 2 years after parathyroidectomy. For the total hip, the increase in BMD was largest at Ward's triangle (42.6%) and smallest at the femoral neck (37.5%). CONCLUSIONS BMD of the lumbar spine and total hip is improved after parathyroidectomy in patients with PHPT.

Abstract
RATIONALE In this report, a combination of platelet-rich fibrin (PRF) membrane and semi-open flap technique was used to improve soft tissue regeneration in immediate implant placement in the molar region. PRF, an autologous fibrin matrix, has been widely used for soft tissue wound healing and regeneration. Semi-open flap technique is beneficial to eliminating exudates and relieving the swelling after surgery. PATIENT CONCERNS Case 1 was a 45-year-old female with a residual crown in the posterior maxillary region that desired a dental implant operation. Case 2 was a 24-year-old male with retained deciduous tooth that requested a restoration of his congenital absent tooth. DIAGNOSES In case 1, the tooth 16 was diagnosed with a residual crown, while in case 2, a deciduous tooth 75 was a retained deciduous tooth and 35 was congenital absent. INTERVENTIONS In both cases, immediate implant placement was installed and PRF membranes were made to improve soft tissue augmentation with semi-open flap technique. In case 1, the mixture of an organic bovine bone and blood was filled in the gap between the implant and the socket wall. Subsequently, 2 PRF membranes covered the open wound with semi-open flap. Similarly, in case 2, another 2 PRF membranes were used to improve the soft tissue regeneration, with the same semi-open flap technique as mentioned above. OUTCOMES In both cases, successfully soft tissue regeneration was obviously observed without postoperative infection. LESSONS Utilizing the PRF membrane combined with semi-open flap technique can achieve excellent soft tissue augmentation around immediate implant placement in the molar regions.

Abstract
BACKGROUND Studies have shown that the response of bone mineral density (BMD) to parathyroidectomy for symptomatic primary hyperparathyroidism (PHPT) is heterogeneous and difficult to predict. However, the independent factors affecting BMD in PHPT patients after parathyroidectomy remains limited and inconclusive. This study aimed to explore the independent factors affecting BMD changes in symptomatic PHPT patients after parathyroidectomy. METHODS This study retrospectively analyzed 105 patients with symptomatic PHPT treated at Beijing Jishuitan Hospital between January 2010 and December 2015. The primary outcome was a > 10% increase in BMD at 3 years after parathyroidectomy compared with the preoperative value, whereas the secondary outcomes were BMD changes at various measurement sites. RESULTS A total of 105 patients with a mean age of 46.37 years were included in this study. Univariate logistic regression analysis indicated that hypertension (odds ratio [OR[: 0.032; 95% confidence interval [CI]: 0.001-0.475; P = 0.012), and parathyroid hormone level (OR: 1.006; 95% CI: 1.004-1.009; P = 0.044) were associated with the > 10% BMD increase. However, these results were not significant after adjustments for potential confounders. Moreover, the BMD values at the lumbar spine, femoral neck, femoral trochanter, Ward's triangle, and whole body after parathyroidectomy were significantly greater than those before the operation (P < 0.05). CONCLUSIONS This study suggests that patient characteristics were not associated with the > 10% BMD increase. However, the BMD values of the femur and lumbar spine were significantly increased in symptomatic PHPT patients after parathyroidectomy.

Abstract
Objective: To investigate the accuracy of bedside transthoracic lung ultrasonography (TLU) in different typical high resolution computed tomography (HRCT) signs of interstitial lung diseases (ILDs). Methods: Fifty patients first diagnosed with ILDs were enrolled from January 2016 to December 2018. There were 21 males and 29 females. The mean age was (56±14) years(rang 42-73 years). TLU was performed in inspiration for the characters of A-lines and B-lines as well as pleural at anterior, lateral and dorsal chest walls, respectively. HRCT was selected at three levels according to the upper, middle, and lower lung fields. The range of each level needing to be evaluated corresponded to the TLU scanning field one by one, and recording the signs of HRCT. Early change of ILDs was definite as the HRCT score was no more than 1 and no honeycomb was present. The correlation between A-lines, B-lines, pleural abnormal and HRCT signs was evaluted. Spearman's correlation coefficient was used to evaluate the relationship between B-lines and HRCT score. Results: The sensitivity and specificity of A-lines for HRCT normality were 83.9% and 84.9%, respectively. Coincidence rate was 84.6%. The sensitivity and specificity of B-lines for HRCT abnormality were 84.9% and 83.9%, respectively. Coincidence rate was 84.6%. Interlobular septal thickening shadow had fewer B-lines and narrower interval than other HRCT signs, while the other HRCT signs had no differences in B-lines. And the sensitivity and specificity of B-lines for detection the early change of HRCT in ILDs were 89.5% and 89.2%, respectively. Coincidence rate was 89.3%. A positive correlation was found between the number of B-lines and HRCT scores (R=0.827, P<0.001), and the width of B-lines and HRCT score (R=0.951, P<0.001). Meanwhile, a negative correlation was found between the interval of B-lines and HRCT score (R=-0.831, P<0.001). The sensitivity and specificity of TLU for HRCT pleural abnormality were 100.0% and 90.0%, respectively. Coincidence rate was 93.6%. Conclusions: TLU showed high sensitivity and specificity in finding interstitial changes of the lung. It gives a new view on the diagnostic possibilities of ILDs and may be used to evaluate the severity and the therapeutic effect of treatment. However, TLU could not differentiate HRCT signs of ILDs.

Abstract
Dampened adenosine A2A receptor (A2AR) function has been implicated in addiction through enhancement of goal-directed behaviors. However, the contribution of the A2AR to the control of impulsive reward seeking remains unknown. Using mice that were exposed to differential reward of low rate (DRL) schedules during Pavlovian-conditioning, second-order schedule discrimination, and the 5-choice serial reaction time task (5-CSRTT), we demonstrate that deficits of A2AR function promote impulsive responses. Antagonism of the A2AR lowered ERK1 and ERK2 phosphorylation in the dorsal hippocampus (dHip) and potentiated impulsivity during Pavlovian-conditioning and the 5-CSRTT. Remarkably, inhibition of ERK1 and ERK2 phosphorylation by U0126 in the dHip prior to Pavlovian-conditioning exacerbated impulsive reward seeking. Moreover, we found decreased A2AR expression, and reduced ERK1 and ERK2 phosphorylation in the dHip of equilibrative nucleoside transporter type 1 (ENT1-/-) null mice, which displayed exacerbated impulsivity. To determine whether impulsive response behavior is associated with hippocampal neuroblast development, we investigated expression of BrdU+ and doublecortin (DCX+) following 5-CSRTT testing. These studies revealed that impulsive behavior driven by inhibition of the A2AR is accompanied by increased neuroblast proliferation in the hippocampus.

Abstract
BACKGROUND Sugarcane mosaic virus (SCMV) is responsible for large-scale economic losses in the global production of sugarcane, maize, sorghum, and some other graminaceous species. To understand the evolutionary mechanism of SCMV populations, this virus was studied in Shanxi, China. A total of 86 maize leaf samples (41 samples in 2012 and 45 samples in 2013) were collected from 4 regions of Shanxi. RESULTS Double-antibody sandwich (DAS)-ELISA and RT-PCR showed 59 samples (30 samples in 2012 and 29 samples in 2013) to be positive for SCMV, from which 10 new isolates of SCMV were isolated and sequenced. The complete genomes of these isolates are 9610 nt long, including the 5' and 3' non-coding regions, and encode a 3063-amino acid polyprotein. Phylogenetic analyses revealed that 24 SCMV isolates could be divided on the basis of the whole genome into 2 divergent evolutionary groups, which were associated with the host species. Among the populations, 15 potential recombination events were identified. The selection pressure on the genes of these SCMV isolates was also calculated. The results confirmed that all the genes were under negative selection. CONCLUSIONS Negative selection and recombination appear to be important evolutionary factors shaping the genetic structure of these SCMV isolates. SCMV is distributed widely in China and exists as numerous strains with distinct genetic diversity. Our findings will provide a foundation for evaluating the epidemiological characteristics of SCMV in China and will be useful in designing long-term, sustainable management strategies for SCMV.

Abstract
The melanocortin 3 receptor (MC3R) gene, which belongs to the rhodopsin-like family A of the G protein-coupled receptor family, plays a crucial role in feed efficiency and energy homeostasis. The aim of this study was to examine associations between bovine MC3R gene polymorphisms and body measurement traits (BMTs) and meat quality traits (MQTs). We identified three synonymous mutations (T429C, T537C, and T663C) in exon 1 of the MC3R gene in Chinese Qinchuan beef cattle (N = 271) by sequencing. D' and r(2) values revealed that these three SNPs were in strong linkage disequilibrium (LD) (r(2) > 0.33); the T429C and T537C SNPs were in complete LD (D' = 1 and r(2) = 1). Association analyses revealed that the SNPs were significantly associated with BMTs and MQTs in Qinchuan cattle. Individuals with the wild homozygotic genotypes g.TTTT and g.TT had significantly higher values of chest depth, heart girth, back fat thickness, intramuscular fat content, and loin muscle area than the mutant heterozygotic genotypes g.TCTC and g.TC. These results suggest that the MC3R gene affects MQTs in Qinchuan cattle, and that it may be a good candidate gene for marker-assisted selection.

Abstract
Dysregulation of the Hippo pathway occurs in a variety of cancers and often correlates with a poor prognosis. To further explore the potential role of Hippo pathway dysregulation in tumor development and progression, we investigated its downstream transcription factor TEAD4 in colorectal cancer (CRC). Increased expression and nuclear localization of TEAD4 were found in a significant portion of CRC tissues, in association with metastasis and a poor prognosis. In CRC cells, TEAD4 knockdown induced the mesenchymal-epithelial transition and decreased cell mobility in vitro and metastasis in vivo. Microarray analysis revealed that TEAD4 promoted cell adhesion and upregulated the epithelial-mesenchymal transition-related transcriptome in CRC cells. Vimentin was identified as a new direct target gene mediating TEAD4 function in CRC cells, whereby forced vimentin expression markedly reversed TEAD4-knockdown-induced cell morphological changes and decreased mobility. Interestingly, rescued expression of both WT TEAD4 and a Y429H mutant can reverse the mesenchymal-epithelial transition and increase vimentin expression, cell mobility and metastatic potential in TEAD4-knockdown CRC cells. The discrepant expression of YAP and TEAD4 in CRC tissues, the rescue ability of TEAD4 mutant defect in YAP binding and no effect on vimentin expression by YAP knockdown in CRC cells, all implicated a YAP-independent manner of TEAD4 function in CRC. Furthermore, vimentin positively correlated and CDH1 reversely correlated with the level of TEAD4 in CRC tissues and xenograft tumors. Our results suggest that TEAD4 nuclear expression can serve as a biomarker for CRC progression and poor prognosis. The transcription factor TEAD4 regulates a pro-metastasis transcription program in a YAP-independent manner in CRC, thus providing a novel mechanism of TEAD4 transcriptional regulation and its oncogenic role in CRC, independently of the Hippo pathway.

Abstract
Background: The role of tumour-infiltrating inflammation in the prognosis of patients with colorectal cancer (CRC) has not been fully evaluated. The primary objective of our meta-analysis was to determine the impact of tumour-infiltrating inflammation on survival outcomes. Methods: Ovid MEDLINE and EMBASE were searched to identify studies reporting the prognostic significance of tumour-infiltrating inflammation for patients with CRC. The primary outcome measures were overall survival (OS), cancer-specific survival (CS) and disease-free survival (DFS). Results: A total of 30 studies involving 2988 patients were identified. Studies were subdivided into those considering the associations between CRC survival and generalised tumour inflammatory infiltrate (n=12) and T lymphocyte subsets (n=18). Pooled analyses revealed that high generalised tumour inflammatory infiltrate was associated with good OS (HR, 0.59; 95% CI, 0.48–0.72), CS (HR, 0.40; 95% CI, 0.27–0.61) and DFS (HR, 0.72; 95% CI, 0.57–0.91). Stratification by location and T lymphocyte subset indicated that in the tumour centre, CD3+, CD8+ and FoxP3+ infiltrates were not statistically significant prognostic markers for OS or CS. In the tumour stroma, high CD8+, but not CD3+ or FoxP3+ cell infiltrates indicated increased OS. Furthermore, high CD3+ cell infiltrate was detected at the invasive tumour margin in patients with good OS and DFS; and high CCR7+ infiltrate was also indicated increased OS. Conclusion: Overall, high generalised tumour inflammatory infiltrate could be a good prognostic marker for CRC. However, significant heterogeneity and an insufficient number of studies underscore the need for further prospective studies on subsets of T lymphocytes to increase the robustness of the analyses.

Abstract
BACKGROUND Cystic fibrosis (CF) is a chronic progressive disease leading to obstructive pulmonary impairment, fibrosis and shortened life expectancy. Serum levels of KL-6, high molecular weight human MUC1 mucin, are increased in the majority of patients with various interstitial lung disorders. Whether they are also elevated in CF has not been investigated before. OBJECTIVE To evaluate whether serum KL-6 levels are elevated and correlate with pulmonary function variables in CF. DESIGN Serum KL-6, lactate dehydrogenase (LDH) and C-reactive protein (CRP) levels were measured in 72 consecutive CF and 80 age- and sex-matched healthy control subjects. The relationship between serum KL-6 levels and pulmonary function variables was analyzed. RESULTS Serum KL-6 levels in CF patients were significantly increased compared to healthy subjects. Receiver operating characteristic curve analysis revealed that the diagnostic accuracy of KL-6 was better than that of LDH and CRP. Serum KL-6 levels showed an inverse relationship with vital capacity (VC) % predicted and forced expiratory volume in one second (FEV1) % predicted. CONCLUSIONS Serum KL-6 levels are elevated and appear to be correlated with pulmonary function variables in CF. These results suggest that KL-6 may be a useful noninvasive marker to monitor disease severity.

Abstract
e15514 Background: Use of anti-angiogenesis drugs in pancreatic cancer has not yet resulted in significant clinical improvements and it is unknown if there are subsets of patients with pancreatic cancer that may benefit from this therapeutic approach. We have reported on a phase II trial of PTK/ZK (VEGFR inhibitor) in patients (n=65) who have failed or progressed on gemcitabine. The 6- month OS met the primary endpoint of 29 % and there were 2 partial responses. We investigated some of the plasma proteins relevant for angiogenesis in correlation with clinical outcomes on this trial. Methods: Plasma samples were obtained prior to and after 4 weeks of therapy with PTK/ZK, aliquoted and frozen until assayed. Patient plasma was assayed for: VEGFA, VEGFC, VEGFR1, VEGFR2, FGFb, PDGFBB, OPN, ANG2, IL-6, and sIL-6R (SearchLight, Pierce Biotechnology Multiplex ELISA and IL-6 and sIL-6R using R&D Systems).The Spearmen correlation was utilized to look for correlations and changes from baseline compared to post-treatment levels. The correlation of baseline levels with survival were analyzed using the Cox proportional hazard model. Results: Thirty eight paired patient samples were assayed. A significant correlation of baseline values was found between VEGF-C and VEGFR1 (p=0.0496), VEGF-C and VEGF (0.0092), PDGFB and ANG2 (p=0.0003), IL-6 and ANG2 (p=0.0089), and FGFb and OPN (p=0.0281). A correlation in post-treatment change was observed between VEGF-C and PDGFB (p=0.0008), FGFb and OPN (p=0.0374), PDGFB and ANG2 (p=0.0005), IL-6 and ANG-2 (p=0.0464), and VEGF and IL-6 (p=0.0546). Lower baseline IL-6 levels correlated with longer survival (p=0.0227). A post-treatment decrease in plasma IL-6 levels was significantly associated with improvement in survival (p=0.0457). IL-6 mediates multiple effects including angiogenic and pro-survival signaling and has been proposed as a potential prognostic factor in different malignancies. Conclusions: Of all angiogenesis markers analyzed only a post-treatment decrease in plasma IL-6 correlated with improved survival on study. IL-6 warrants further investigation as a potential marker of sensitivity to anti-angiogenesis therapy, especially in patients with pancreatic cancer.

Abstract
A real-time polymerase chain reaction assay was initially developed in China to detect mumps genome. The primers and TaqMan-MGB probe were selected from regions of the hemagglutinin gene of mumps virus. The primers and probe for the real-time PCR were evaluated by both laboratories in China and in the UK using three different pieces of equipment, LightCycler (Roche), MJ DNA Engine Option 2 (BIO-RAD) and TaqMan (ABI Prism) on different samples. The reaction was performed with either a one-step (China) or two-step (UK) process. The sensitivity (10 copies) was estimated using a serial dilution of constructed mumps-plasmid DNA and a linear standard curve was obtained between 10 and 10(7) DNA copies/reaction, which can be used to quantify viral loads. The detection limit on cell culture-grown virus was approximately 2 pfu/ml with a two-step assay on TaqMan, which was equivalent to the sensitivity of the nested PCR routinely used in the UK. The specificity was proved by testing a range of respiratory viruses and several genotypes of mumps strains. The concentration of primers and probe is 22 pmol and 6.25 or 7 pmol respectively for a 25 microl reaction. The assay took 3 hr from viral RNA extraction to complete the detection using any of the three pieces of equipment. Three hundred forty-one (35 in China and 306 in the UK) clinical specimens were tested, the results showing that this real-time PCR assay is suitable for rapid and accurate detection of mumps virus RNA in various types of clinical specimens.
