Abstract
AIMS The lipid reference intervals (RIs) that are currently used for children in China are not based on studies of the local population and normally do not consider age or gender differences. This study aimed to establish age- and sex-specific RIs for the fasting serum lipid levels in the pediatric population aged 0 - 15 years in Nanjing, China. METHODS 5,866 children aged 3 days to <15 years were recruited to establish serum lipid RIs, and the triglyceride (TG), total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) levels were analyzed using the Roche cobas702 automatic biochemical analyzer. Low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (nHDL-C) levels were calculated (LDL-C=TC-HDL-C-TG/5, and nHDL-C=TC-HDL-C). Smoothed percentile curves for the boys and girls were generated using the LMS method. Age- and sex-specific RIs were the determined according to the methods recommended by the Clinical and Laboratory Standards Institute EP28-A3c guidelines. RESULTS This study showed that the serum lipid levels varied considerably throughout childhood and adolescence, with sex differences, especially in infants aged less than 2 years and puberty. Based on the Harris-Boyd method, sex partitions were required for ages <6 months in the TC indicator and for ages ≤ 28 days in LDL-C and nHDL-C. Age partitions were also required for all serum lipid parameters. CONCLUSIONS We established age- and sex-specific RIs for TG, TC, HDL-C, LDL-C, and nHDL-C parameters in children aged 0 days to <15 years in Nanjing, China. These data are thus considered to be useful for the screening of dyslipidemia in children and adolescents.

Abstract
Compiling evidence supports that selenium plays a vital role in glucose metabolism. Triglyceride-glucose index (TyG) and triglyceride-glucose-body mass index (TyG-BMI) are commonly used in epidemiologic studies to evaluate insulin resistance and cardiovascular disease (CVD) risks. This study is aimed to investigate the association between whole blood selenium concentration and TyG and TyG-BMI. A total of 6290 participants (age ≥ 20 years) from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 were included. Multiple linear regression models were used to examine the association between blood selenium quartiles and TyG and TyG-BMI. Subgroup analysis stratified by diabetes status was also performed. The adjusted model showed a positive association between TyG and blood selenium concentration (β [95%CI] = 0.099 [0.063, 0.134], p < 0.001) and TyG-BMI (β [95%CI] = 3.185 [2.102, 4.268], p < 0.001). The association persisted after stratification by diabetes status (p < 0.001). Participants were stratified into four quartiles based on selenium concentration (Q1: 1.08-2.24 μmol/L, Q2: 2.25-2.42 μmol/L, Q3: 2.43-2.62 µmol/L, Q4: 2.63-8.08). Compared with the Q1 group, TyG in the Q3 and Q4 groups was significantly higher (β = 0.075 [95%CI 0.039 to 0.112] and β = 0.140 [95%CI 0.103 to 0.176], respectively). Additionally, TyG-BMI in the Q2, Q3, and Q4 groups was higher than that in the Q1 group (β = 1.189 [95%CI 0.065 to 2.314], β = 2.325 [95%CI 1.204 to 3.446], and β = 4.322 [95%CI 3.210 to 5.435], respectively). Blood level of selenium was positively associated with TyG and TyG-BMI, indicating that excessive blood selenium may be associated with impaired insulin sensitivity and increased risk of cardiovascular disease.

Abstract
Objective The coronavirus disease (COVID-19) and the public health responses were associated with a huge health burden, which could influence sleep quality. This meta-analysis and systematic review examined the prevalence of poor sleep quality in COVID-19 patients. Methods PubMed, Web of Science, Embase, and PsycINFO were systematically searched from their respective inception to October 27, 2022. Prevalence rates of poor sleep were analyzed using a random effects model. Results Totally, 24 epidemiological and 12 comparative studies with 8,146 COVID-19 patients and 5,787 healthy controls were included. The pooled prevalence of poor sleep quality based on the included studies was 65.0% (95%CI: 59.56-70.44%, I2 = 97.6%). COVID-19 patients had a higher risk of poor sleep quality compared to healthy controls (OR = 1.73, 95% CI: 1.30-2.30, p < 0.01, I2 = 78.1%) based on the 12 comparative studies. Subgroup analysis revealed that COVID-19 patients in low-income countries (p = 0.011) and in studies using a lower Pittsburgh Sleep Quality Index score cut-off (p < 0.001) were more likely to have poor sleep quality. Meta-regression analyses revealed that being female (p = 0.044), older (p < 0.001) and married (p = 0.009) were significantly correlated with a higher risk of poor sleep quality while quality score (p = 0.014) were negatively correlated with the prevalence of poor sleep quality in COVID-19 patients. Conclusion Poor sleep quality was found to be very common in COVID-19 patients. Considering the negative effects of poor sleep quality on daily life, sleep quality should be routinely assessed and appropriately addressed in COVID-19 patients.

Abstract
Poor sleep quality is prevalent among members of the military but rates of poor sleep quality vary between studies. This study examined the global prevalence of poor sleep quality in military personnel and veterans as well as possible moderators of prevalence differences between studies. PubMed, EMBASE, Web of Science, and PsycINFO were systematically searched from their inception dates to September 1, 2022. Studies were included if they were conducted on military personnel and/or veterans and prevalence estimates of poor sleep quality could be generated from assessments with standardized tools. A random-effects model was used to calculate the pooled prevalence and its 95% confidence intervals (CIs). Fifty-nine studies (N = 28,100) were included for analysis with sample sizes ranging from 14 to 8481. Two studies were rated as "high quality" (3.39%), while 57 were rated as "moderate quality" (96.61%). The overall pooled prevalence of poor sleep quality in military personnel and veterans was 69.00% (95% CI: 62.33-75.30%); pooled rates were 57.79% (95% CI: 49.88-65.50%) and 82.88% (95% CI: 74.08-90.21%) for active duty personnel and veterans, respectively. Subgroup analyses indicated study region, study design, sampling method, Pittsburg Sleep Quality Index cut-off values, and service type moderated prevalence of poor sleep quality. Meta-regression analyses indicated sample size, mean age, depression and posttraumatic stress disorder (PTSD) were associated with prevalence differences between studies. Poor sleep quality was more common in both active duty military personnel and veterans who were older and those who reported PTSD or depression. Regular monitoring of sleep quality and sleep hygiene should be promoted in this population. More relevant studies in middle- and low-income countries should also be conducted.

Abstract
The aim of the study was to test whether the cytokine profile could be used as a marker to differentiate between Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) and Kawasaki disease (KD). A total of 70 hospitalized children with HLH and KD admitted to hospital for the first time from March 2017 to December 2021 were enrolled in this study. Fifty-five healthy children were enrolled as normal controls. All patients and normal controls were tested for the six cytokines including interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), and interferon-γ (IFN-γ) by flow cytometry. IL-10 and IFN-γ levels were significantly higher in children with EBV-HLH than in the KD, IL-6 was lower in EBV-HLH patients than in the KD. IL-10/IL-6 ratio, IFN-γ/IL-6 ratio and IL10/IFN-γ ratio in children with EBV-HLH were significantly much higher than children in the KD group. When the diagnostic cutoff values of IL-10, IFN-γ, IL-10/IL-6 ratio and IFN-γ/IL-6 ratio were >13.2 pg/ml, >71.0 pg/ml, >0.37 and >1.34, respectively, the sensitivity and specificity of the diagnosis of EBV-HLH disease were 91.7% and 97.1%, 72.2% and 97.1%, 86.1% and 100.0%, and 75.0% and 97.1%, respectively. Notably high IL-10 and IFN-γ and moderately elevated IL-6 suggest the diagnosis of EBV-HLH, while high IL-6 levels with low IL-10 or IFN-γ concentration would suggest KD. Additionally, IL-10/IL-6 ratio or IFN-γ/IL-6 ratio could be used as an index to differentiate between EBV-HLH and KD.

Abstract
Caspase recruitment domain and membrane-associated guanylate kinase-like protein 3 (CARMA3) is a scaffold protein widely expressed in non-hematopoietic cells. It is encoded by the caspase recruitment domain protein 10 (CARD10) gene. CARMA3 can form a CARMA3-BCL10-MALT1 complex by recruiting B cell lymphoma 10 (BCL10) and mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1), thereby activating nuclear factor-κB (NF-κB), a key transcription factor that involves in various biological responses. CARMA3 mediates different receptors-dependent signaling pathways, including G protein-coupled receptors (GPCRs) and receptor tyrosine kinases (RTKs). Inappropriate expression and activation of GPCRs and/or RTKs/CARMA3 signaling lead to the pathogenesis of human diseases. Emerging studies have reported that CARMA3 mediates the development of various types of cancers. Moreover, CARMA3 and its partners participate in human non-cancer diseases, including atherogenesis, abdominal aortic aneurysm, asthma, pulmonary fibrosis, liver fibrosis, insulin resistance, inflammatory bowel disease, and psoriasis. Here we provide a review on its structure, regulation, and molecular function, and further highlight recent findings in human non-cancerous diseases, which will provide a novel therapeutic target.

Abstract
BACKGROUND The COVID-19 pandemic could increase the number of older adults who are socially isolated including community-dwelling older adults, and result in the secondary damage of mental health. This study aimed to examine the longitudinal association between social isolation transitions and psychological distress among the community-dwelling older adults before and during the COVID-19 pandemic in rural China. METHODS A total of 2749 community-dwelling older adults aged 60 years and older in rural Shandong, China were included. We used the generalized estimating equations (GEE) model to estimate the impact of social isolation transitions on psychological distress before and during the COVID-19 pandemic. RESULTS The percentage of high and very high psychological distress (K10 ≥ 22) was 23.54% and 31.36% before and during the COVID-19 pandemic, respectively, indicating a 7.82% increase (P < 0.001). Compared with the group remaining nonisolated, "became socially isolated" and "remained isolated" groups were more likely to have a deterioration of psychological distress after experiencing the COVID-19 pandemic (became socially isolated: b = 0.92, P < 0.001; remained isolated: b = 0.98, P < 0.001). LIMITATIONS The main variables in this study were measured by self-report information, which might result in recall bias. CONCLUSIONS During the COVID-19 pandemic, psychological distress increased among the community-dwelling older adults in rural China. There was a significant risk of psychological distress among those who had transitioned from nonisolation before the pandemic to social isolation after experiencing the pandemic, thus intervention on social isolation process during the pandemic may be important to protect older adults' mental health.

Abstract
Acute kidney injury (AKI) is a clinical syndrome characterized by morbidity, mortality, and cost. Cis-diamminedichloroplatinum (cisplatin) is a chemotherapeutic agent used to treat solid tumors and hematological malignancies, but its side effects, especially nephrotoxicity, limit its clinical application. Isoliquiritin (ISL), one of the major flavonoid glycoside compounds in licorice, has been reported to have anti-apoptotic, antioxidant, and anti-inflammatory activities. However, the effect and mechanism of ISL on cisplatin-induced renal proximal tubular cell injury remain unknown. In this study, mouse proximal tubular cells (mPTCs) and human proximal tubule epithelial cells (HK2) were administered increasing concentrations of ISL from 7.8125 to 250 μM. Moreover, mPTC and HK2 cells were pretreated with ISL for 6–8 h, followed by stimulation with cisplatin for 24 h. CCK-8 assay was performed to evaluate the cell viability. Apoptosis and reactive oxygen species (ROS) of cells were measured by using flow cytometer and western blotting. Our results showed that ISL had no obvious effect on cell viability. ISL decreased cisplatin-induced cell injury in a dose-dependent manner. ISL also protected against cisplatin-induced cell apoptosis. Meanwhile, the enhanced protein levels of Bax, cleaved caspase-3/caspase-3 ratio, levels of Pp-65/p-65, levels of IL-6, and the production of ROS induced by cisplatin were significantly attenuated by ISL treatment. Moreover, ISL markedly increased the protein levels of Bcl-2 and SOD2, which were reduced by cisplatin stimulation. These results showed that ISL ameliorated cisplatin-induced renal proximal tubular cell injury by antagonizing apoptosis, oxidative stress and inflammation.

Abstract
Background Some studies found that family doctor contract services (FDCSs) had positive impact on the self-measurement behaviors of hypertension patients. However, evidence concerning the association between FDCSs and blood pressure measurement awareness among hypertension patients is not clear. Objective This study aims to explore the relationship between FDCSs and blood pressure measurement awareness among the hypertension patients, and examine whether there is a difference in this relationship among middle-aged and aged adults in rural Shandong, China. Methods A multi-stage stratified random sampling was adopted in 2018 in Shandong Province to conduct a questionnaire survey among the sample residents, in which 982 hypertension patients were included in the study. Pearson chi-square test and logistic regression model were employed using SPSS 24.0 to explore the association between FDCSs and blood pressure measurement awareness. Results 76.8% of hypertension patients would measure blood pressure regularly. The blood pressure measurement awareness of the signing group was significantly higher than that of the non-signing group when controlling other variables (P < 0.001, OR = 2.075, 95% CI 1.391–3.095). The interaction of age and contracting status were significantly correlated with blood pressure measurement awareness (P = 0.042, OR = 1.747, 95% CI 1.020–2.992; P = 0.019, OR = 2.060, 95% CI 1.129–3.759). Factors including gender (P = 0.011, OR = 0.499, 95% CI 0.291–0.855), household income (P = 0.031, OR = 1.764, 95% CI 1.052–2.956), smoking status (P = 0.002, OR = 0.439, 95% CI 0.260–0.739), sports habits (P < 0.001, OR = 2.338, 95% CI 1.679–3.257), self-reported health (P = 0.031, OR = 1.608, 95% CI 1.043–2.477), distance to the village clinic (P = 0.006, OR = 1.952, 95% CI 1.208–3.153) and medications (P < 0.001, OR = 3.345, 95% CI 2.282–4.904) were also found to be associated with the blood pressure measurement awareness of hypertension patients. Conclusion The government should take efforts to strengthen publicity and education of family doctors and pay more attention to uncontracted, middle-aged, female patients and patients with unhealthy life behaviors to improve the blood pressure measurement awareness.

Abstract
BACKGROUND many studies explore the relationship between social capital and self-rated health. However, few studies clarified the mechanisms underlying the relationship between social capital and self-rated health among Chinese rural empty nesters. This study aimed to explore the multiple mediating roles of sleep quality and psychological distress between this relationship. METHODS A total of 2,254 rural empty-nest older adults were included in the analysis. A descriptive analysis was conducted to describe the sample characteristics. Logistic regressions were performed to assess the relationships between social capital and self-rated health. The multiple mediating roles of sleep quality and psychological distress was analyzed using Mplus 8.3. RESULTS we found that social capital has a significant directly affect self-rated health (β=0.127, 68.65% CI=0.082-0.171), and through three significantly mediation pathways: (1) the path through sleep quality (β=0.013, 95% CI=0.005-0.021), which accounted for 7.03% of the total effect; (2) the path through psychological distress (β=0.037, 95% CI=0.024-0.049), which accounted for 20.00% of the total effect; (3) the path through sleep quality and psychological distress (β=0.008, 95% CI=0.004-0.013), which accounted for 4.32% of the total effect. The total mediating effect was 31.35%. CONCLUSIONS sleep quality and psychological distress mediate the relationship between social capital and self-rated health. Attention should be paid to mental health and sleep quality of empty nester through primary health, strengthen the attention to social resources, provide intervention and treatment for the empty nesters with sleep problem and psychological distress.

Abstract
Psychological distress were found to be associated with chronic conditions and persistent pain. However, few studies explored the underlying pathways between them. This study aimed to analyze the path of chronic conditions and persistent pain on psychological distress through sleep quality and self-rated health. A total of 2,748 rural older people in Shandong, China were included in this study. Path analysis was performed by using Mplus 8.3 to examine the associations between chronic conditions, persistent pain, sleep quality, self-rated health, and psychological distress after adjusting for age, gender, education, and household income. The prevalence of psychological distress among the older adults in this study was 47.49%. Chronic conditions and persistent pain were indirectly associated with psychological distress through six mediating pathways: (1) the path from chronic conditions to psychological distress through sleep quality (β = 0.041, 95%CI: 0.015-0.067) and self-rated health (β = 0.064, 95%CI: 0.038-0.091), respectively, and a chain mediation existed (β = 0.007, 95% CI: 0.000-0.014); (2) the path of persistent pain and psychological distress through sleep quality (β = 0.058, 95% CI: 0.014-0.102) and self-rated health (β = 0.048, 95% CI: 0.000-0.096), respectively, also the chain mediation found (β = 0.009, 95% CI: 0.005-0.014). Psychological distress was associated with chronic conditions and persistent pain through decreased sleep quality and self-rated health among Chinese rural older people. Multi-pronged targeted intervention should be taken for older adults with chronic conditions and persistent pain.

Abstract
Background Family doctor policy is an important part of deepening healthcare reform in China. The study aimed to explore the association between cardiovascular-metabolic multimorbidity and the status of signing a contract for family doctor services among the older people in rural Shandong, China. Methods A cross-sectional study was conducted in 3 cities of Shandong province, China. A total of 1395 rural residents over 60 years of age were included in this study using a multistage stratified random sampling method. Covariates included demographic and socioeconomic characteristics, health-related characteristics, health service utilization, and awareness of family doctor contract services. The univariate and multivariate regression logistic analysis was used to analyze the data. Results There were 28.2% of the rural older people contracted for the family doctor contract services. The contract rate of seniors with cardiovascular-metabolic multimorbidity was statistically higher than those without cardiovascular-metabolic multimorbidity (OR = 1.67, 95%CI, 1.21-2.32) after controlling for confounding factors. In addition, occupation, physical activities, self-rated health status, distance from the village clinic, the awareness of family doctor contract services were found to be associated with the signing behavior among the rural older adults. Conclusion This study demonstrated that the rural older people with cardiovascular-metabolic multimorbidity had a higher family doctor contract rate than those without cardiovascular-metabolic multimorbidity, and there was a gap between the current signing rate and the policy goal. To increase the rate of signing for family doctor contract services, the government should take joint efforts to expand the publicity and coverage, and give priority to meeting the healthcare demands of rural older adults with cardiovascular-metabolic multimorbidity.

Abstract
BACKGROUND Rural residents with chronic conditions have a stronger need for health services, which should make using family doctor contract services a priority. This study aimed to evaluate the rate of willingness among rural residents with chronic conditions to contract with family doctors and examine its determinants. METHODS A cross-sectional study was conducted from May, 2018 to June, 2018 in Shandong Province in China. A total of 769 rural unsigned residents with chronic conditions were included in the analysis. Using the Andersen model as the theoretical framework, logistic regression models were chosen to analyse the factors associated with willingness to contract with family doctors. RESULTS This study found that the rate of willingness to contract with family doctors among chronic patients in rural Shandong was 46.7%. A higher willingness was observed in those living a further distance from the village clinic (more than 600 m: OR = 1.85, 95%CI =1.17-2.93), having received publicity for family doctor contract services (OR = 1.71, 95% CI = 1.06-2.76), reporting need for utilizing a chronic disease management program (OR = 3.36, 95% CI = 2.20-5.23), and reporting need for higher medical insurance reimbursement (OR = 1.91, 95% CI = 1.28-2.83). CONCLUSIONS The prevalence of contract willingness was relatively low among unsigned rural residents with chronic conditions in rural Shandong, China. The need factors were powerful factors affecting their willingness to contract with family doctors. The government should therefore strengthen targeted publicity and education to rural residents with chronic conditions and provide targeted healthcare services, such as chronic disease management programs and medical services with higher reimbursement rates, to promote their willingness to contract with family doctors.

Abstract
Purpose Few studies explored the relationship between the family doctor contract services (FDCS) and health-related quality of life (HRQOL) among patients with chronic diseases in rural China. This study aims to explore the relationship between the status of signing on FDCS and HRQOL among patients with chronic diseases and examine whether there are differences in the relationship between different socioeconomic status (SES). Methods A total of 1,210 respondents were included in this study. HRQOL was measured by EQ-5D-3L. The contracting status was divided into uncontracted and contracted. Tobit regression and Logistic regression were employed to explore the association between contracting status and HRQOL. The interaction terms were included to explore the differences in the association among different SES. Results Contracting with family doctors was associated with HRQOL (coefficient = 0.042; 95%CI 0.008 to 0.075). The association was different among different socioeconomic levels that the contracting status was only associated with HRQOL in sub-high-income (P < 0.01) and highly educated patients (P < 0.05). Compared with uncontracted patients, contracted patients reported higher ED-5D-3L utility value in the sub-high-income group (coefficient = 0.078; 95%CI 0.017 to 0.140) and high educational attainment (coefficient = 0.266; 95%CI 0.119 to 0.413). Conclusions This study found a significant association between FDCS and HRQOL among chronic patients in rural Shandong, China. This relationship varied by income levels and educational attainment. The government should take efforts to formulate a variety of measures to encourage chronic patients to contract with family doctors, with special attention to people with low SES.

Abstract
The function of miR16 in multiforme glioblastoma multiforme (GBM) and its stem cells (GSCs) remains elusive. To this end, we investigated the patterns of miR16 expression in these cells and their correlation with malignant behaviors and clinical outcomes. The levels of miR16 and its targeted genes in tumor tissue of GBM and GBM SGH44, U87, U251 cells as well as their stem cell counterparts were measured by qRT–PCR or western blot or immunohistochemistry. Luciferase reporter assay was used to confirm the binding of miR16 to 3′-UTR of its target genes. The effects of miR16 on malignant behaviors were investigated, including tumor cell viability, soft-agar colony formation, GSCs Matrigel colony forming and migration and invasion as well as nude mice xenograft model. Differentially expression patterns of miR16 in glioblastoma cells and GSCs cells were found in this study. Changes of miR16 targeted genes, Bcl2 (B cell lymphoma 2), CDK6 (Cyclin-dependent kinase 6), CCND1 (cyclin D1), CCNE1 (cyclin E1) and SOX5 were confirmed in glioblastoma cell lines and tissue specimens. In vitro and in vivo studies showed that tumor cell proliferation was inhibited by miR16 mimic, but enhanced by miR16 inhibitor. The expression level of miR16 positively correlates with GSCs differentiation, but negatively with the abilities of migration, motility, invasion and colony formation in glioblastoma cells. The inhibitory effects of miR16 on its target genes were also found in nude mice xenograft model. Our findings revealed that the miR16 functions as a tumor suppressor in GSCs and its association with prognosis in GBM.

Abstract
As an emerging noninvasive blood biomarker, circulating free DNA (cfDNA) can be utilized to assess diagnosis, progression and evaluate prognosis of cancer. However, cfDNAs are not "naked", they can be part of complexes, or are bound to the surface of the cells via proteins, which make the detection more challenging. Here, a simple method for the detection of Ubiquitin-like with PHD and ring finger domains 1 (UHRF1) DNA exacted from serum of breast cancer (BC) has been developed using a novel locked nucleic acid molecular beacon (LNA-MB). In order to enhance the stability and detection efficiency of the probe in biofluids, we design a shared-stem molecular beacon containing a 27-mer loop and a 4-mer stem with DNA/LNA alternating bases. The fluorescence is released in the presence of target. The detection procedure is simple and can be completed within 1h. This method shows a sensitive response to UHRF1 DNA with a dynamic range of 3 orders of magnitude. The limit of detection is 11nM (S/N=3) with excellent selectivity. It can discriminate UHRF1 DNA from three-base mismatched DNA with a high specificity. More importantly, this method can distinguish the expression of serum UHRF1 DNA among 5 breast cancer patients and 5 healthy controls. The mentioned superiority may suggest that this assay can be served as a promising noninvasive detection tool for early BC diagnosis and monitoring.

Abstract
The UHRF1 protein is pivotal for DNA methylation and heterochromatin formation, leading to decreased expressions of tumor suppressor genes and contributing to tumorigenesis. However, the factors that modulate UHRF1 expression in colorectal cancer (CRC) remain unclear. Here we showed that, compared with corresponding normal tissues, UHRF1 was upregulated and microRNA-9 (miR-9) was downregulated in CRC tissues. The expression of UHRF1 was inversely correlated with overall survival rates of patients with CRC. Overexpression of miR-9 in CRC cell lines significantly attenuated CRC cell proliferation and promoted cell apoptosis. The expression of UHRF1 was markedly reduced in pre-miR-9 transfected CRC cells. Using luciferase reporter assay, we confirmed that miR-9 was a direct upstream regulator of UHRF1. Finally, analysis of miR-9 and UHRF1 levels in human CRC tissues revealed that expression of miR-9 was inversely correlated with UHRF1 expression. Collectively, our results offer in vitro validation of the concept that miR-9 could repress the expression of UHRF1, and function as a tumor-suppressive microRNA in CRC. It may serve as a prognostic and therapeutic marker for CRC.

Abstract
In this study, 2 approaches were adopted to obtain good single-strand conformation polymorphism (SSCP) data for autotetraploid alfalfa; primers were added to PCR products, and fluorescent-labeled primers were utilized. PCR-SSCP conditions for a 331-bp fragment in the coding region of polygalacturonase-inhibiting protein gene 2 in alfalfa (MsPGIP2) were optimized, and the results showed that the best SSCP gel pattern could be obtained when the loading mixture was made by mixing 1 μL PCR products, 0.2 to 0.8 μL unlabeled primers (50 μM) and 4 to 16 μL loading buffer. Furthermore, the use of the fluorescent-labeled primers resulted in 2 separated electrophoresis images from 2 complementary single DNA strands, thus making the determination of alleles and idiotypes a relatively easy task. In addition, the results of sequencing prove that the determination of alleles and idiotypes were accurate based on SSCP analysis. Finally, a total of 9 alleles with 18 SNP sites were identified for MsPGIP2 in the alfalfa variety 'Algonquin'. In conclusion, MsPGIP2 possessed great genetic variation, and the addition of primers to the PCR products in combination with the fluorescent labeling of primers could significantly improve the sensitivity and resolution of SSCP analysis. This technique could be used for genetic diversity detection and marker-assisted breeding of useful genes in autopolyploid species such as alfalfa.

Abstract
Combining temperature-dependent x-ray diffraction, Raman spectroscopy and first-principles-based effective Hamiltonian calculations, we show that varying the thickness of (Ba0.8Sr0.2)TiO3 (BST) thin films deposited on the same single substrate (namely, MgO) enables us to change not only the magnitude but also the sign of the misfit strain. Such previously overlooked control of the strain allows several properties of these films (e.g. Curie temperature, symmetry of ferroelectric phases, dielectric response) to be tuned and even optimized. Surprisingly, such desired control of the strain (and of the resulting properties) originates from an effect that is commonly believed to be detrimental to functionalities of films, namely the existence of misfit dislocations. The present study therefore provides a novel route to strain engineering, as well as leading us to revisit common beliefs.

Abstract
The signal variations induced by respiration and cardiac motion decrease the statistical significance in functional MRI data analysis. Significant components of these fluctuations are aliased into the activation spectrum in standard multi-slice imaging protocols. A method of estimation and removal physiological noise in image space is reported. Based on reordering the data from slice ordering to time ordering, the aliased physiological information is available in multi-slice magnitude images. Then physiological noise can be estimated and removed adaptively using signal projecting technique with the actual functional signal preserved.
