ABSTRACT
Purpose@#The prevalence of multi-morbidities with colorectal cancer (CRC) is known to be increasing. Particularly prognosis of CRC patients co-diagnosed with metabolic syndrome (MetSyn) was largely unknown. We aimed to examine the death risk of CRC patients according to the multiple MetSyn morbidities. @*Materials and Methods@#We identified CRC patients with MetSyn from the electronic medical records (EMR) systems in five independent hospitals during 2006-2011. Information on deaths was jointly retrieved from EMR, cause of death registry and chronic disease surveillance as well as study-specific questionnaire. Cox proportional hazards regression was used to calculate the overall and CRC-specific hazards ratios (HR) comparing MetSyn CRC cohort with reference CRC cohort. @*Results@#A total of 682 CRC patients in MetSyn CRC cohort were identified from 24 months before CRC diagnosis to 1 month after. During a median follow-up of 92 months, we totally observed 584 deaths from CRC, 245 being in MetSyn cohort and 339 in reference cohort. Overall, MetSyn CRC cohort had an elevated risk of CRC-specific mortality (HR, 1.49; 95% confidence interval [CI], 1.07 to 1.90) and overall mortality (HR, 1.43; 95% CI, 1.09 to 1.84) compared to reference cohort after multiple adjustment. Stratified analyses showed higher mortality risk among women (HR, 1.87; 95% CI, 1.04 to 2.27) and specific components of MetSyn. Notably, the number of MetSyn components was observed to be significantly related to CRC prognosis. @*Conclusion@#Our findings supported that multi-morbidities of MetSyn associated with elevated death risk after CRC. MetSyn should be considered as an integrated medical condition more than its components in CRC prognostic management.

ABSTRACT
Non-syndromic hearing loss (NSHL) is a common defect in humans. Variants of MARVELD2 at the DFNB49 locus have been shown to cause bilateral, moderate to profound NSHL. However, the role of MARVELD2 in NSHL susceptibility in the Chinese population has not been studied. Here we conducted a case-control study in an eastern Chinese population to profile the spectrum and frequency of MARVELD2 variants, as well as the association of MARVELD2 gene variants with NSHL. Our results showed that variants identified in the Chinese population are significantly different from those reported in Slovak, Hungarian, and Czech Roma, as well as Pakistani families. We identified 11 variants in a cohort of 283 NSHL cases. Through Sanger sequencing and bioinformatics analysis, we found that c.730G>A variant has detrimental effects in the eastern Chinese population, and may have relatively high correlation with NSHL pathogenicity.

ABSTRACT
Objective To explore structural differences of intestinal flora in primary insomnia patients with different TCM syndromes through the high-throughput 16S rDNA sequencing analysis. Methods Totally 65 patients with primary insomnia were divided into 22 patients with syndrome of liver depression transforming into fire, 17 patients with deficiency of both heart and spleen syndrome, 26 patients with syndrome of hyperactivity of fire due to yin deficiency, with 47 cases of healthy people as the control group. The fecal flora structure of the subjects was analyzed by high-throughput 16S rDNA sequencing. QIIME software and R language stats package were used to analyze the diversity of flora. Results Totally 1226 different operational taxonomic units (OUTs) were obtained, and there were 180 significant differences among the 4 groups (P<0.05), indicating that the samples were rich in microbial colonies. The mapped reads in group of liver depression transforming into fire and hyperactivity of fire due to yin deficiency were more than the group of deficiency of both heart and spleen and the control group (P<0.05). Unweighted UniFrac analysis showed that the difference among groups was remarkably greater than the difference within group, and the grouping was statistically significant (R=0.103, P=0.002). It suggested that the diversity of intestinal flora was highly correlated with different TCM syndromes of insomnia. There were a total of 57 genera found significant differences among the different groups at the genus level (P<0.05), and 115 species at all species level. The dominant flora of the control group were prevotella, megamonas, clostridium Ⅺ (clostridium ⅩⅧ), weissella, and alloprevotella; The dominant flora of liver depression transforming into fire syndrome were phascolarctobacterium, flavonifractor, eggerthella, and bilophila; The dominant flora of deficiency of both heart and spleen syndrome were sphingomonas and methylobacterium; The dominant flora in hyperactivity of fire due to yin deficiency syndrome group were bacteroides, parabacteroides, parasutterella, butyricimonas, odoribacter. Conclusion The patients with primary insomnia have abundant intestinal flora diversity and diverse flora structure, which may affect the occurrence, development and outcome of different TCM syndromes.

ABSTRACT
The aim of the present study was to measure the kinetic parameters of skeletal muscle protein synthesis in rats by deuterated water (HO). Twenty Sprague-Dawley (SD) rats were labeled byHO through intraperitoneal injection and drinking. At the each end of the 1st, 3rd, 5th, 6th and 10th week after the firstHO labeling, four rats were sacrificed by cardiac puncture for blood plasma and quadriceps femoris sampling. Skeletal muscle protein and free amino acids in plasma were purified, hydrolyzed by hydrochloric acid and derived. The deuterium enrichments ofH-labeled alanyl in skeletal muscle protein and plasma protein-boundH-labeled alanine were determined by gas chromatography-mass spectrometry (GC-MS). The fractional synthesis rate of skeletal muscle protein and synthetic dynamic equation were calculated. The fractional synthetic rate of skeletal muscle protein was 12.8%/week, and synthetic dynamic equation was f= 0.158 × (1 - e). The results suggest that the kinetic parameters of skeletal muscle protein synthesis can be measured byHO labeling, and the method can be applied in long-term labeling experiment.

ABSTRACT
Objective To investigate the role of miR?193a?3p in the radioresistance of esophageal squamous cell carcinoma ( ESCC) . Methods MTT assay was used to identify the cell lines with the highest radiosensitivity and radioresistance in four esophageal cancer cell lines exposed to irradiation of 6 MV X?ray. Stem?loop quantitative real?time PCR was used to measure the expression levels of miR?193a?3p, miR?155, and miR?22?3P in the two cell lines. Further studies were performed on miR?193a?3p because of the substantial difference in its expression between the two cell lines. The mimic (3PM) and antagomiR (3PA) of miR?193a?3p as well as siRNA ( si?LOXL4) were synthesized and transfected into cells to elevate and inhibit miR?193a?3p expression. MTT assay and flow cytometry were used to evaluate the effects of miR?193a?3p and its downstream gene LOXL4 on radiosensitivity. Results KYSE510 and KYSE410 were characterized as cell lines with the highest radiosensitivity and radioresistance, respectively. miR?193a?3p had a substantially larger difference in expression between the two cell lines than miR?155 or miR?22?3P (1. 00 ∶ 21. 00). Transfection of 3PM resulted in elevated expression of miR?193a?3p in KYSE510, which had a significantly lower radiosensitivity and a significantly reduced apoptosis ratio by 11. 01% compared with the control group ( P<0. 05) . KYSE410 transfected with 3PA had a significantly higher radiosensitivity ( P<0. 05) . The expression of LOXL4, a downstream gene of miR?193a?3p, was negatively correlated with miR?193a?3p expression. Transfection with si?LOXL4 inhibited the expression of LOXL4, which resulted in a significantly lower radiosensitivity and a significantly reduced apoptosis ratio by 7. 07% compared with the control group ( P<0. 05) . Conclusions miR?193a?3p promotes the radioresistance of esophageal cancer cells probably by regulation of LOXL4.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the methylation status in promoter region of norepinephrine transporter gene (NET, SLC6A2) in heart failure ( HF) patients and its correlation with qi deficiency/blood stasis syndrome (QDS/BSS).</p><p><b>METHODS</b>Thirty-six patients with heart failure (NYHA classification III to IV) were recruited in the study (as the heart failure group) and their scores of QDS/BSS were evaluated. Besides, a healthy elderly group (30 cases) and a healthy youth group (30 cases) were also set up. They were recruited from Physical Examination Center of Fujian Provincial Hospital. Pyrosequencing was applied to detect the methylation in promoter region of SLC6A2 gene, and the total methylation index (MTI) of CpG island was calculated. The correlation between the methylation status in promoter region of SLC6A2 and scores of QDS/BSS was assessed using Pearson and Partial analyses. Risk factors were screened and adjusted using Logistic regression.</p><p><b>RESULTS</b>By one-factor analysis of variance, the total MTI in the HF group (219.72% ± 54.03%) was obviously higher than that in the healthy elderly group (194.47% ± 34.92%) and the healthy youth group (161.60% ± 41.11%) (all P < 0.05). Meanwhile, the total MTI was higher in the healthy elderly group than in the healthy youth group (P < 0.01). By covariance analysis , after controlling age and BMI, the total MTI was higher in the HF group than in the healthy elderly group (P = 0.041), while it was higher in the healthy elderly group than in the healthy youth group (P = 0.016). Age was found to play an essential role in affecting MTI of SLC6A2 gene promoter region among the 3 groups (F = 16.447, P = 0.01). The total MTI was quite lower in the healthy youth group. Results of Partial correlation analysis showed MTI was positively correlated with scores of qi deficiency and blood stasis respectively (r = 0.494 and 0.419 respectively, both P < 0.05). Logistic regression analysis showed after adjusting confounding factors, the relative risk (OR value) of total MTI of SLC6A2 gene in promoter region was 1.038 (95% CI, 1.006 to 1.071, P = 0.020).</p><p><b>CONCLUSIONS</b>Abnormally elevated methylation of the promoter region of SLC6A2 gene is one of risk factors for HF. In addition, the degree of methylation of the promoter region of SLC6A2 gene was positively correlated with the severity of QDS/BSS.</p>

Objective To investigate the expression and clinical significance of tumor-associated carbohydrate anti-gen sTn in endometrium from patients with atypical hyperplasia of endometrium, endometrial carcinoma and benign the uter-ine lesion. And to analyze the association between sTn and the pathologic stage and grade of endometrial carcinoma. Meth-ods sTn was detected by immunohistochemistry in 193 patient samples, including 93 subjects with endometrial carcinoma, 50 subjects with atypical hyperplasia of endometrium and 50 subjects with benign uterine lesions. Results The positive sTn rate in endometrial carcinoma group was 73.1%,which was significantly different from that in atypical hyperplasia endo-metrium group (32%) and that in benign uterine lesion group (14%), (P＜0.017). sTn positive rate in patients with endometri-al carcinoma was 78.8%which is higher than that in patients with other diseases (P＜0.008 ). The positive rate of sTn in pa-tients with poorly differentiated endometrial carcinoma was significantly higher than that in patients with highly differentiat-ed endometrial carcinoma (P＜0.017). The positive rate of sTn in tissues of tumor infiltration with depth of more than half of myometrial was significantly higher than in tissues of tumor infiltration with depth of equal or less than half of myometrial (P＜0.05). But there was no significant difference in sTn positive rate between the endometrial carcinoma groups with and without lymph node metastasis (P>0.05). Conclusion sTn may play a role in the tumorigenesis and development of endo-metrial carcinoma.
ABSTRACT
Along with the degree of population ageing worse off continuously, the demand for medical service is growing. The current system of pension service and medical service are discrete and separate, and integrating pen-sion service with medical service is the best choice for China. However, there are some problems with the model for integrating pension service with medical service. These problems include the lack of funding, negative participation and imperfect methods of service delivery; high toll levels and single, rigid service contents; and bull management and policies hard to enforce. China should improve the service delivery model, identify service content according to the demand for service object, and improve the mechanism of government management.

<p><b>OBJECTIVE</b>To explore the potential role of miR-195 on invasiveness and prognosis of breast cancer.</p><p><b>METHODS</b>The RNA in formalin-fixed paraffin embedded (FFPE) of 88 breast cancer patients with primary tumors was extracted, and miR-195 levels were quantified by quantitative real-time polymerase chain reaction (real-time PCR). The relationship of miR-195 levels and clinicopathological variables were assessed by Mann Whitney-U test. Recurrence-free survival and overall survival curves were derived from Kaplan-Meier estimates and the curves were compared by Log-rank tests. Cox regression analysis was used for multivariate analysis. All statistical tests were two-sided.</p><p><b>RESULTS</b>The levels of miR-195 in the breast cancer with histological high grade, tumor size of T3-4, lymph nodal involvement or vessel invasion were significantly down-regulated, compared with those of patients with histological low grade (Z = -2.271, P = 0.023), tumor size of T1-2 (Z = -2.687, P = 0.007), no lymph node metastasis (Z = -1.967, P = 0.049) and vessel invasion (Z = -2.432, P = 0.015). In addition, no statistically significant difference (P > 0.05) was identified between miR-195 levels and hormone receptors status, HER-2 expression, TNM stage, tumor types, recurrence and menstrual status. When considering 2(-ΔCt) = 0.270 (median level) as cut-off value, Kaplan-Meier survival analysis indicated that patients with high miR-195 level showed a positive association towards a longer survival, either recurrence-free survival (χ(2) = 5.985, P = 0.014) or overall survival (χ(2) = 30.05, P = 0.000). In a multivariate analysis, miR-195 expression on FFPE correlated significantly with outcomes of breast cancer (HR = 0.040, 95%CI: 0.009 - 0.179, P = 0.000) and was independent of other prognostic factors.</p><p><b>CONCLUSIONS</b>It suggests that miR-195 expression on FFPE is inversely correlated with histological high grade, bigger tumor size, lymph node involvement, vessel invasion. Furthermore, as independent prognostic factor, low miR-195 significantly contributes to poor outcomes of breast cancer.</p>

No significant difference (χ(2) = 0.449, P = 0.799) was reached by χ(2) test. rs1563828CT or TT genotype does not confer a significantly increased risk for breast cancer compared with CC genotype after adjusting for age, menarche in Logistic regression analysis (OR = 1.024, 95%CI: 0.581 - 1.806, P = 0.934). TT carriers were observed to develop breast cancer earlier than CC/CT carriers [(30 ± 4) years vs. (32 ± 3) years, P = 0.028].</p><p><b>CONCLUSIONS</b>The rs1563828(C > T) polymorphism in MDM4 gene may not confer risk to breast cancer, especially for early-onset breast cancer patients. Homozygous TT of rs1563828 is associated with younger age to develop breast cancer.</p>

<p><b>OBJECTIVE</b>To investigate the potential use of miR-155 as novel breast cancer biomarker.</p><p><b>METHODS</b>There were 88 breast cancer patients underwent modified mastectomy and had detailed clinical follow-up information. Extracting RNA from the formalin-fixed paraffin embedded (FFPE) samples, miR-155 levels were quantified by real-time-PCR. miR-155 levels among clinico-pathological variables were accessed by Mann Whitney-U test. Overall survival curve was derived from Kaplan-Meier estimates and the curve was compared by Log-rank test. Cox regression analysis was used for multivariate analysis. All statistical tests were two-sided.</p><p><b>RESULTS</b>Significantly higher miR-155 level was found in tumor tissue compared to paired normal tissue (t = 6.75, P = 0.000). A potential relationship between miR-155 levels and existing clinico-pathological parameters of breast cancer, such as menstrual status, tumor size, nodal involvement, stage of disease, hormone receptor status, HER-2 status, histological grade or tumor subtype was investigated. Up-regulated miR-155 level was observed in breast cancer with lymph node metastasis, pT3+4, advanced TNM stage, HER-2 positive and with vascular invasion (Z = -6.320 to -2.041, P = 0.000 to 0.041). When considering 2(-ΔCt) = 4.87 (median level) as cut-off value, patients with miR-155 up-regulation showed a positive association towards a shorter overall survival (χ(2) = 6.396, P = 0.011). In Cox multivariate analysis, miR-155 expression on FFPE was shown an inverse trend for outcomes of breast cancer (HR = 1.58, 95%CI: 0.87 - 3.16, P = 0.082).</p><p><b>CONCLUSIONS</b>miR-155, as an oncomir, promotes lymph node involvement and vascular invasion and accompanies over-expressed HER-2 on breast cancer FFPE tissue. It suggests that miR-155 could predict the invasiveness.</p>
