Abstract
Objective: To study the expression status and clinical significance of PTEN and NDRG1 in colorectal carcinoma. Methods: Tissue samples of 91 colorectal cancers, 30 colorectal adenomas and 21 colorectal normal mucosa tissues were collected. Postoperative specimens were examined by immunohistochemistry for PTEN and NDRG1 expression. The expression of PTEN and NDRG1 was correlated with clinicopathological feature. Results: The expression of PTEN and NDRG1 in the studied cases was detected in 55.0%(50/91) and 76.9%(70/91), respectively. Their expression was significantly different from that of colorectal adenomas and normal colorectal mucosa tissues(P<0.05). Decreased expression of PTEN and over expression of NDRG1 were significantly related to the lymph node metastasis (P<0.05). The expression of PTEN was negatively related to that of NDRG1 in colorectal carcinoma(rs'=-0.251, P=0.016). The patients with negative expression of PTEN showed a lower disease free survival and overall survival(P<0.05). Conclusions: Loss of expression of PTEN protein may be an important molecular marker in predicting the occurrence and PTEN may be useful as a prognostic marker of colorectal carcinoma. NDRG1 plays a role in the development of colorectal carcinoma, although not a prognostic indicator.The ancillary study with combined detection of PTEN and NDRG1 may be useful in difficult cases.

Abstract
Objective: To investigate the incidence, molecular features and clinical significance of RNA splicing machinery genes mutation in myelodysplastic syndromes (MDS) and related diseases. Methods: Mutational analysis of splicing factor 3B subunit 1 (SF3B1) (K700E) , U2 small nuclear RNA auxiliary factor 1 (U2AF1) (S34, Q157P) and serine/arginine-rich splicing factor 2 (SRSF2) (P95) in 118, de novo MDS and related diseases were separately performed by using polymerase chain reaction (PCR) followed by sequence analysis. Results: Of 118 MDS patients, 76 males and 42 females, the median age was 53.5 (13-84) years old. 19.49% (23/118) had SF3B1 (K700E) mutation. As compared with those with wild type SF3B1, patients with SF3B1 K700E were of older[58 (32-78) years vs 51 (13-84) years, z=-1.981, P=0.048], lower HGB level[63 (40-95) g/L vs 77 (34-144) g/L, z=-3.192, P=0.001], higher platelet counts[121 (22-888) ×10(9)/L vs 59 (6-1 561) ×10(9)/L, z=-3.305, P=0.001], lower bone marrow blast cell counts[0.007 (0-0.122) vs 0.017 (0-0.268) , z=-2.885, P=0.004], higher ring sideroblasts percent [0 (0-64%) vs 0 (0-58%) , z=-4.664, P<0.001]. Of 105 MDS patients, 21.9% had U2AF1 (S34, Q157P) mutations. Of 107 MDS patients, 8 patients (7.48%) had SRSF2 (P95) mutations. Patients with SRSF2 mutations were older at diagnosis, the median age was 63 (50-84) years old, including 4 cases RAEB-1. The ratio of mutation was 14.29% (4/28) , and three patients transformed to AML. SF3B1 K700E and SRSF2 P95H mutations coexisted in 1 patient, and SF3B1 K700E and U2AF1 S34Y mutations were found concomitantly in 2 patients. Conclusion: Only SF3B1 gene mutation was closely related to ring sideroblasts, it was the key to pathogenesis of MDS.

Abstract
In male Caucasians with discordant hip bone mineral density (BMD), we applied the subcellular separation and proteome profiling to investigate the monocytic cytosol. Three BMD-associated proteins (ALDOA, MYH14, and Rap1B) were identified based on multiple omics evidence, and they may influence the pathogenic mechanisms of osteoporosis by regulating the activities of monocytes. INTRODUCTION Osteoporosis is a serious public health problem, leading to significant mortality not only in aging females but also in males. Peripheral blood monocytes (PBMs) play important roles in bone metabolism by acting as precursors of osteoclasts and producing cytokines important for osteoclast development. The first cytosolic sub-proteome profiling analysis was performed in male PBMs to identify differentially expressed proteins (DEPs) that are associated with BMDs and risk of osteoporosis. METHODS Here, we conducted a comparative proteomics analysis in PBMs from Caucasian male subjects with discordant hip BMD (29 low BMD vs. 30 high BMD). To decrease the proteome complexity and expand the coverage range of the cellular proteome, we separated the PBM proteome into several subcellular compartments and focused on the cytosolic fractions, which are involved in a wide range of fundamental biochemical processes. RESULTS Of the total of 3796 detected cytosolic proteins, we identified 16 significant (P < 0.05) and an additional 22 suggestive (P < 0.1) DEPs between samples with low vs. high hip BMDs. Some of the genes for DEPs, including ALDOA, MYH14, and Rap1B, showed an association with BMD in multiple omics studies (proteomic, transcriptomic, and genomic). Further bioinformatics analysis revealed the enrichment of DEPs in functional terms for monocyte proliferation, differentiation, and migration. CONCLUSIONS The combination strategy of subcellular separation and proteome profiling allows an in-depth and refined investigation into the composition and functions of cytosolic proteome, which may shed light on the monocyte-mediated pathogenic mechanisms of osteoporosis.

Abstract
Epithelial–mesenchymal transition (EMT) has been recognized as a key element of cell migration and invasion in lung cancer; however, the underlying mechanisms are not fully elucidated. Recently, emerging evidence suggest that miRNAs have crucial roles in control of EMT and EMT-associated traits such as migration, invasion and chemoresistance. Here, we found that miR-218 expression levels were significantly downregulated in lung cancer tissues compared with adjacent non-cancerous tissues, and the levels of miR-218 were significantly associated with histological grades and lymph node metastasis. Overexpression of miR-218 inhibited cell migration and invasion as well as the EMT process. Of particular importance, miR-218 was involved in the metastatic process of lung cancer cells in vivo by suppressing local invasion and distant colonization. We identified Slug and ZEB2 as direct functional targets of miR-218. Inverse correlations were observed between miR-218 levels and Slug/ZEB2 levels in cancer tissue samples. In addition, overexpression of miR-218 in H1299 increased chemosensitivity of cells to cisplatin treatment through suppression of Slug and ZEB2. These findings highlight an important role of miR-218 in the regulation of EMT-related traits and metastasis of lung cancer in part by modulation of Slug/ZEB2 signaling, and provide a potential therapeutic strategy by targeting miR-218 in NSCLC.

Abstract
OBJECTIVE Recent study observed defective autophagy in chondrocytes with Kashin-Beck Disease (KBD). To clarify the potential role of autophagy-related ATG4C gene in the development of KBD, we conducted an integrative analysis of genetic association, messenger ribonucleic acid (mRNA) and protein expression of ATG4C in KBD patients. METHODS 1026 subjects (559 KBD patients and 467 healthy cases) were enrolled in discovery association study. Four single nucleotide polymorphisms (SNPs) of ATG4C gene (rs11208030, rs4409690, rs12097658 and rs6587988) were genotyped by Sequenom MassARRAY platform. Association analysis was conducted by PLINK software. The significant SNPs of ATG4C were replicated using an independent sample of 899 subjects (including 90 KBD patients and 809 healthy controls). Ungenotyped SNPs in ATG4C gene were imputed by IMPUTE 2.0. Knee cartilage specimens were collected from five KBD patients and five healthy subjects. Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot were performed to compare the mRNA and protein expression levels of ATG4C between KBD cartilage and control cartilage. RESULTS We observed significant association between KBD and rs11208030 (P value = 0.003), rs4409690 (P value = 0.004), rs12097658 (P value = 0.003) and rs6587988 (P value = 0.003) in both discovery and replication samples. The mRNA expression level of ATG4C (ratio = 0.168, P value = 0.007) in KBD chondrocytes was significantly lower than that in normal chondrocytes. Western blot (P value < 0.001) further confirmed the reduced expression of ATG4C protein in both KBD cartilage and chondrocytes. CONCLUSION Our results strongly suggest that ATG4C was a novel autophagy-related susceptibility gene of KBD.

Abstract
Objective: To investigate the epidemiological features of abnormal urinary fluoride rates in population with occupational exposure, and its relationships with age, work years and gender in Shanghai. Methods: A questionnaire survey was conducted respectively in 4 999 exposed workers and 283 non-exposed people during 2012-2015. Their urine samples were collected in plastic bottles and the fluoride ion selective electrode method was used for urinary fluoride level analysis. Logistic regression model was used to estimate associations between the abnormal rates and demographic/socioeconomic status of the study subjects. Results: In the past 4 years, the abnormal urinary fluoride rates (≥1.6 mg/L) in the population with occupational exposure was about 14.38%, it was about 1.43% in the control groups without occupational exposure. Their geometric mean of urinary fluoride content was 0.95 mg/L and 0.46 mg/L, respectively. The incidences of the abnormal rates in those aged ≥50 years and 34-39 years were 19.15% and 22.39%, respectively. The abnormal rate in males was 16.87%, much higher than that in females (6.85%). The abnormal rate had an upward trend along with the increased work years, especially in those with work years of ≥20 years. The abnormal rate was 23.28% in those with work years of ≥20 years and 13.29% in those with work years of <4 years. The relative risk for abnormal urinary fluoride rates was higher in male group, older age group and longer work year group, the odds ratio was 2.28, 1.10 and 1.13, respectively. Conclusions: Serious challenges exist in occupational health supervision. The relevant national standards should be updated as soon as possible. Males, those aged >50 years, and those with longer work years are the risk groups for intervention measures. More efforts are needed, such as strengthening the innovative application of health examination data and the equalization of basic public health service with comprehensive occupational health supervision programs among off-farm workers in the new medical reform.

Abstract
OBJECTIVE To evaluate the efficacy and safety of domestic human recombinant FSH(rhFSH)in women with anovulation of WHO group Ⅱ. METHODS A randomized, blind, parallel-controlled, non-inferiority and multicenter study was performed. A total of 534 admitted to 13 hospitals from May 2008 to August 2009. There were 531 women with ovulatory disorder was included in the statistical analysis, were randomly divided into test group(domestic rhFSH, n=352)and control group(imported rhFSH, n=179). Percentage of cycle with mature follicle, ovulation rate, clinical pregnancy rate, multiple pregnancy rate, ovarian hyperstimulation syndrome(OHSS)and adverse events were observed. RESULTS No statistical significant differences(P>0.05)were observed between the two groups in terms of the efficiency on mature follicle[91.8%(323/352)versus 88.8%(159/179)], ovulation rate[91.3%(295/323)verus 90.6%(144/159)], clinical pregnancy rate[19.2%(62/323)verus 18.2%(29/159)], the number of the follicles<14 mm, the level of serum LH and progesterone, the thickness of endometrium on the day of hCG administration. The number of follicle≥18 mm and 14 mm≤follicle<18 mm and the level of serum estradiol on the day of hCG in the test group were significantly higher than those in the control group(P<0.05). The number of days of rhFSH administration in the test group was significantly less than that in the control group[(9.8±2.2)versus(11.4± 0.6)days, P<0.05], the dosage of rhFSH was significantly lower than that in the control group[(879 ± 419)versus(1 043±663)U, P<0.05]. The multiple pregnancy rate in the test group was significantly higher than that in the control group[21%(13/62)versu 10%(3/29), P<0.05]. The incidence of OHSS and adverse events were similar between the two groups(P>0.05), and no other adverse events were observed in test group during treatment. CONCLUSION Ovarian stimulation with domestic rhFSH is effective, safe and economical in women with anovulation of WHO group Ⅱ.

Abstract
Objective: To investigate the effects of in utero exposure to high-dose di- n-butyl phthalate (DBP) on testicular cell apoptosis in late embryonic and pubertal male rat offspring. Methods: Twenty pregnant Sprague-Dawley (SD) rats were divided into two groups. During gestation day (GD) 12 to GD 19, control group was given 1 ml day−1 of olive oil and experimental group was given DBP 500 mg kg−1 day−1 by gavage. On GD 19.5 and postnatal day (PND) 45, the testes were removed. Morphological analysis of the testes was observed by transmission electron microscopy and hematoxylin and eosin (H&E) staining. Testicular cell apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). The expression of Bcl-2, Bax, and p53 was presented by immunohistochemistry (IHC) and western blot. Data of the two groups was compared using independent samples t-test and Mann–Whitney test by SPSS 20.0. Results: H&E staining showed that spermatogenetic cells were significantly decreased in DBP exposed pubertal rat testis. The apoptosis index of testes in DBP-treated group was significantly lower on GD 19.5 but higher on PND 45 than that of the controls ( p < 0.01). IHC and western blot revealed significantly increased expression of Bcl-2 in GD 19.5 rat testis and Bax and p53 in PND 45 rat testis after DBP exposure, compared with the control ( p < 0.05). Conclusion: In utero exposure of high-dose DBP resulted in opposite effects on testicular cell apoptosis in late embryonic and pubertal rat offspring. The overexpression of Bcl-2, Bax, and p53 might be related to the occurrence of abnormal apoptosis and finally produce male infertility.

Abstract
Residential solid fuels are widely consumed in rural China, contributing to severe household air pollution for many products of incomplete combustion, such as polycyclic aromatic hydrocarbons (PAHs) and their polar derivatives. In this study, concentrations of nitrated and oxygenated PAH derivatives (nPAHs and oPAHs) for household and personal air were measured and analyzed for influencing factors like smoking and cooking energy type. Concentrations of nPAHs and oPAHs in kitchens were higher than those in living rooms and in outdoor air. Exposure levels measured by personal samplers were lower than levels in indoor air, but higher than outdoor air levels. With increasing molecular weight, individual compounds tended to be more commonly partitioned to particulate matter (PM); moreover, higher molecular weight nPAHs and oPAHs were preferentially found in finer particles, suggesting a potential for increased health risks. Smoking behavior raised the concentrations of nPAHs and oPAHs in personal air significantly. People who cooked food also had higher personal exposures. Cooking and smoking have a significant interaction effect on personal exposure. Concentrations in kitchens and personal exposure to nPAHs and oPAHs for households using wood and peat were significantly higher than for those using electricity and liquid petroleum gas (LPG).

Abstract
OBJECTIVES Body mass index (BMI) is one of the major factors affecting the development of osteoarthritis (OA) but there is currently no information available regarding the relationship between BMI and Kashin-Beck disease (KBD). Our aim in this study was to investigate the relationship and genetic overlap between BMI and KBD. METHOD A total of 2050 Han Chinese subjects participated in this study. Using a cohort of 333 grade I KBD patients, logistic regression analysis was conducted to evaluate the correlation between BMI and KBD. Another independent sample of 1717 subjects was genotyped for a genome-wide association study (GWAS) using Affymetrix Human SNP 6.0 Arrays. Single nucleotide polymorphism (SNP) effect concordance analysis (SECA) was applied to the GWAS summaries of KBD and BMI for pleiotropy analysis. Genome-wide bivariate association analysis (GWBAA) of KBD and BMI was carried out to identify the genes with pleiotropic effects on KBD and BMI. The relevance of identified genes with KBD was validated by gene expression profiling and immunohistochemistry. RESULTS BMI correlated positively with knee movement disorder in KBD (coefficient β = 0.068, p = 0.045). SECA identified a significant pleiotropic effect (empirical p = 0.021) between KBD and BMI. In the GWBAA, the rs1893577 of the ADAMTS1 gene achieved the most significant association signal (p = 7.38 × 10-9). ADAMTS1 was also up-regulated in KBD vs. normal (ratio = 2.64 ± 2.80) and KBD vs. OA (ratio = 2.31 ± 2.01). The rate of ADAMTS1-positive chondrocytes in KBD was significantly higher than that in OA (p < 0.05) and healthy controls (p < 0.05). CONCLUSIONS Our results suggest that ADAMTS1 is a novel susceptibility gene for KBD.

Abstract
UNLABELLED We performed a GWAS of trochanter and intertrochanter bone mineral density (BMD) in the Framingham Heart Study and replicated in three independent studies. Our results identified one novel locus around the associated variations at chromosomal region 3q13.32 and replicated two loci at chromosomal regions 3p21 and 8q24. Our findings provide useful insights that enhance our understanding of bone development, osteoporosis, and fracture pathogenesis. INTRODUCTION Hip trochanter (TRO) and intertrochanter (INT) subregions have important clinical relevance to subtrochanteric and intertrochanteric fractures but have rarely been studied by genome-wide association studies (GWASs). METHODS Aiming to identify genomic loci associated with BMD variation at TRO and INT regions, we performed a GWAS utilizing the Framingham Heart Study (FHS, N = 6,912) as discovery sample and utilized the Women's Health Initiative (WHI) African-American subsample (N = 845), WHI Hispanic subsample (N = 446), and Omaha osteoporosis study (N = 971), for replication. RESULTS Combining the evidence from both the discovery and the replication samples, we identified one novel locus around the associated variations at chromosomal region 3q13.32 (rs1949542, discovery p = 6.16 × 10-8, replication p = 2.86 × 10-4 for INT-BMD; discovery p = 1.35 × 10-7, replication p = 4.16 × 10-4 for TRO-BMD, closest gene RP11-384F7.1). We also replicated two loci at chromosomal regions 3p21 (rs148725943, discovery p = 6.61 × 10-7, replication p = 5.22 × 10-4 for TRO-BMD, closest gene CTNNB1) and 8q24 (rs7839059, discovery p = 2.28 × 10-7, replication p = 1.55 × 10-3 for TRO-BMD, closest gene TNFRSF11B) that were reported previously. We demonstrated that the effects at both 3q13.32 and 3p21 were specific to the TRO, but not to the femoral neck and spine. In contrast, the effect at 8q24 was common to all the sites. CONCLUSION Our findings provide useful insights that enhance our understanding of bone development, osteoporosis, and fracture pathogenesis.

Abstract
Charcot-Marie-Tooth (CMT) is the most common inherited peripheral neuropathy, affecting approximately 2.8 million people. The CMT leads to distal neuropathy that is characterized by reduced motor nerve conduction velocity, ataxia, muscle atrophy and sensory loss. We generated a mouse model of CMT type 2E (CMT2E) expressing human neurofilament light E396K (hNF-LE396K ), which develops decreased motor nerve conduction velocity, ataxia and muscle atrophy by 4 months of age. Symptomatic hNF-LE396K mice developed phenotypes that were consistent with proprioceptive sensory defects as well as reduced sensitivity to mechanical stimulation, while thermal sensitivity and auditory brainstem responses were unaltered. Progression from presymptomatic to symptomatic included a 50% loss of large diameter sensory axons within the fifth lumbar dorsal root of hNF-LE396K mice. Owing to proprioceptive deficits and loss of large diameter sensory axons, we analyzed muscle spindle morphology in presymptomatic and symptomatic hNF-LE396K and hNF-L control mice. Muscle spindle cross-sectional area and volume were reduced in all hNF-LE396K mice analyzed, suggesting that alterations in muscle spindle morphology occurred prior to the onset of typical CMT pathology. These data suggested that CMT2E pathology initiated in the muscle spindles altering the proprioceptive sensory system. Early sensory pathology in CMT2E could provide a unifying hypothesis for the convergence of pathology observed in CMT.

Abstract
The novel Eriocheir sinensis reovirus (EsRV) is a pathogen that causes severe disease and high mortality rates in cultivated crabs. Here, we established a highly sensitive and specific rapid reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay that was cheaper and more suitable for field applications in crab aquaculture than those of traditional reverse transcription-polymerase chain reaction (RT-PCR) analysis. The amplification was completed within 45 min under isothermal conditions at 65°C. The RT-LAMP test for EsRV had a detection limit of 15 pg, and sensitivity was 100 times greater than that of conventional RT-PCR. The LAMP primers for EsRV were not amplified by other pathogen strains, indicating good specificity. In addition to detection by electrophoresis, RT-LAMP results were detectable by visual observations of reaction tube turbidity, and calcein was added to visually detect the amplification products. These results indicate that this highly convenient, rapid and sensitive RT-LAMP assay can be used to detect EsRV-infected aquatic organisms. SIGNIFICANCE AND IMPACT OF THE STUDY Tremor disease (TD) is one of the most serious diseases of Eriocheir sinensis. A novel E. sinensis reovirus (EsRV) was identified from E. sinensis afflicted with TD and caused high mortality. We developed a reverse transcription loop-mediated isothermal amplification assay with high specificity, sensitivity and rapidity to detect EsRV, which can be used to diagnose aquatic animal diseases, particularly where expensive diagnostic instruments are not available.

Abstract
OBJECTIVE To objectively evaluate visual function by pattern visual evoked potential (PVEP) and its related factors in patients with obstructive sleep apnea syndrome (OSAS)without any ocular symptoms. METHODS Eighty-three newly diagnosed OSAS and 18 normal subjects were enrolled in the study. The OSAS patients were divided into mild (n=11), moderate(n=17) and severe (n=55) groups based on the apnea-hypopnea index(AHI). Before the polysomnography(PSG) test, all participants underwent a PVEP examination measuring the latency and amplitude of P100. RESULTS Compared to healthy controls, the latency of P100 was significantly increased in OSAS patients [controls group: 97(95-100) ms, mild OSAS group: 101(98-103) ms, moderate OSAS group: 101(98-105) ms, severe OSAS group: 105(101-108) ms, all P<0.05], and the amplitude of P100 was significantly reduced [controls group: 9(8-10) μV, mild OSAS group: 7(5-8) μV, moderate OSAS group: 6(5-7) μV, severe OSAS group: 6(4-7) μV, all P<0.05]. The severe group showed significantly longer latency of P100 when compared with mild and moderate groups(P<0.05). In the OSAS patients, univariate analysis showed that, the latency of P100 was correlated with ODI, T90, AHI, sleep efficiency, minimum SaO2, and mean SaO2, and the amplitude of P100 was statistically associated with sleep efficiency .But the stepwise multiple linear regression analysis revealed that only AHI was significantly correlated with the latency of P100 (r=0.275, P<0.01). CONCLUSION Abnormal PVEP was found in patients with OSAS without any clinical manifestations of the optic neuropathy. The dysfunction of optic nerve was significantly associated with AHI and sleep efficiency.

Abstract
BACKGROUND Lower cervical spine dislocation remains a surgical challenge. METHODS Twelve patients with lower cervical dislocation due to articular process injury underwent dorsal open reduction and manual pedicle screw rod fixation. Patients with cervical spinal cord injury received simultaneous open door expansive laminoplasty. Neurological function was evaluated using ASIA Impairment Scale 12. RESULTS Median time from injury to operation was 10 days (range, 5 to 52 days). Anatomic reduction was achieved in all patients. In nine patients with cervical spinal cord injury, 55.5% (5/9) showed improvement in ASIA grade following surgery. Unilateral numbness of the superior radicular area in one patient resolved 2 weeks post-surgery and two cases (11.1%, 2/9) had postoperative leakage of the cerebrospinal fluid, which resolved in 11 days and 13 days, respectively. CONCLUSION Dorsal open reduction and manual pedicle screw rod fixation is safe and effective for lower cervical spine dislocation due to articular process injury.
