Abstract
Objective: To quantify the associations between periconceptional maternal homocysteine (HCY) and offspring's birth weight and risk of small for gestational age (SGA) infant. Methods: The 19 984 mother-child pairs in this prospective cohort study were recruited from the Shanghai preconception cohort; the infants were delivered from 1st September 2016 to 11th November 2022. A standardized questionnaire was used to collect the mothers' demographic information, medical history, dietary supplement use, and maternal complications during pregnancy, and their serum samples were collected. Serum HCY, folate, and vitamin B12 were measured using chemiluminescent microparticle immunoassay based on serum sample drawn at enrollment. Birth weight data were obtained from medical records. Multiple imputation methods were applied to handle missing data in key variables. Multivariable linear regression and Poisson regression models were used to analyze the relationship between maternal HCY concentration during the periconceptional period and the birth weight and SGA risk of the offspring. Results: A total of 9 452 pairs were enrolled preconceptionally and the remaining 10 532 pairs were enrolled in early pregnancy. The proportion of mothers whose pregnancy age was greater than 35 years was 9.2% (1 832/19 984), the proportion of primiparous women was 76.5% (15 283/19 984), the proportion of pre-pregnancy overweight and obesity was 14.0% (2 804/19 984), the proportion of using folic acid supplements before pregnancy was 21.4% (4 272/19 984), and the proportion of those who supplemented with folic acid during early pregnancy was 85.2% (8 976/10 532); gestational diabetes mellitus was in 6.2% (1 245/19 984), gestational hypertensive syndrome in 3.6% (711/19 984). The birth weight of the offspring was (3 297±468) g, and there were 1 962 SGA children (9.8%). The HCY concentration in the overall population in appropriate for gestational age during the periconceptional period was (7.9±3.2) μmol/L, with (8.3±3.7) μmol/L in the preconception subgroup and (7.3±2.4) μmol/L in the early pregnancy subgroup. After adjustment for the covariates of perinatal demographic information, adverse pregnancy outcomes, serum folate and vitamin B12, increased maternal periconceptional HCY was significantly associated with lower offspring birth weight (β=-2.30, 95%CI -4.43--0.16, P=0.035). Only the early pregnancy subgroup was significantly associated with lower offspring birth weight (β=-7.39, 95%CI-11.50--3.21, P<0.001). No association was found between peripregnancy HCY and offspring SGA risk. However, elevated HCY in early pregnancy was associated with an increased risk of SGA in the offspring (RR=1.05, 95%CI 1.01-1.08, P=0.002). Periconceptional vitamin B12 was a mediator of the association between HCY and offspring birth weight, accounting for 16.5%, 41.2% and 5.4% of its total effect in the overall periconceptional population, the pre-pregnancy subgroup and the early pregnancy subgroup, respectively. Conclusions: Maternal periconceptional HCY level is associated with lower birth weight in offspring, but not with the risk of SGA. Elevated maternal HCY in early pregnancy subgroup may be associated with increased risk of SGA in offspring.

Abstract
Objective: To explore the efficacy of myocardial protection with single-dose histidine-tryptophan-ketoglutarate (HTK) cardioplegia during aortic root operation, and the correlation between short-term clinical outcomes and duration of myocardial ischemia. Methods: The data of clinical cases undergoing myocardial protection with single-dose HTK cardioplegia during aortic root operation from January 2018 to December 2022 were retrospectively reviewed. Patients were divided into conventional HTK cardioplegia group (<3 h) and prolonged HTK cardioplegia group (≥3 h) according to duration of intraoperative myocardial ischemia. A 1∶1 propensity score matching was performed and the correlations between duration of myocardial ischemia and postoperative short-term outcomes (30-day mortality, readmission, mechanical circulation support and renal insufficiency) were analyzed. Results: A total of 282 patients were included in the final analysis, with 210 cases in the conventional HTK cardioplegia group and 72 cases inthe prolonged HTK cardioplegia group before matching. After matching, there were 64 cases (53 males and 11 females) in the conventional HTK cardioplegia group, with a mean age of (49.4±14.2) years. The prolonged HTK cardioplegia group had 64 cases (55 males and 9 females), with a mean age of (50.5±12.3) years. Higher sensitivity troponin [12 h: 10.1 (4.6, 18.7) μg/Lvs 4.1(2.2, 8.6) μg/L, P=0.002; 24 h: 7.7 (4.5, 19.0) μg/L vs 4.8 (2.2, 11.9) μg/L, P=0.025] and creatine kinase isoenzyme[12 h: 46.3 (28.1, 62.4) μg/L vs 20.7(14.1, 32.9) μg/L, P<0.001; 24 h: 26.3(13.4, 49.2) μg/L vs 14.5 (10.1, 33.5)μg/L, P=0.011] after surgery was detected in prolonged HTK cardioplegia group. Comparisons of other primary and secondary endpoint events showed no significant differences between the two groups (all P>0.05). Multivariate binary logistic regression showed that duration of myocardial ischemia had no significant effect on postoperative 30-day mortality (OR=1.255, 95%CI: 0.500-3.148, P=0.629), 30-day readmission (OR=0.378, 95%CI: 0.069-2.065, P=0.261) and mechanical circulation support (OR=0.991, 95%CI: 0.331-2.970, P=0.998). Conclusion: During aortic root surgery, single-dose HTK cardioplegia may provide satisfactory myocardial protection, and there was no significant correlation between duration of myocardial ischemia and short-term clinical outcomes.

Abstract
This study attempted to investigate whether exosomes derived from rat endothelial cells (EC-Exo) attenuate intimal hyperplasia after balloon injury using hematoxylin and eosin staining, immunohistochemistry, immunofluorescence staining, Evans blue staining, and Western blotting. The results indicated that EC-Exo inhibited intimal hyperplasia in the carotid artery after balloon injury, promoted re-endothelialization, and reduced vascular inflammation and ROS-NLRP3-mediated cell pyroptosis. Thus, EC-Exo can inhibit neointimal hyperplasia after carotid artery injury in rats presumably by inhibiting the ROS-NLRP3 inflammasome and phenotypic transformation of vascular smooth muscle cells.

Abstract
Coal is one of the major fuels, which brings huge energy and economic benefits to global industry and daily life. large amounts of coal dust produced in the process of coal mining and transportation, which seriously threatens the health of related workers. Productive coal dust exposure not only directly leads to respiratory diseases, but also may cause health damage to various systems throughout the body. Numerous studies have shown that coal dust exposure is closely associated with decreased lung function, coal worker's pneumoconiosis, chronic obstructive pulmonary disease, lung cancer, and cardiovascular diseases, and the severity of diseases is affected by coal rank, coal dust concentration, cumulative dust exposure, coal dust composition, and individual lifestyle, etc. The article comprehensively summarized the progress of the epidemiological studies on the health hazards of coal miners from coal dust exposure, in order to provide clues for further researches on health damage and protect the health of the occupational population.

Abstract
Objective: To investigate the effect of continuous intravenous infusion of subanesthetic dose of esketamine intraoperatively on postoperative opioid consumption in patients undergoing thoracoscopic surgery. Methods: A total of 71 patients with elective thoracoscopic lung surgery in the First Affiliated Hospital of Zhengzhou University from December 2020 to December 2021 were selected. Patients who were classified as grade Ⅰ or Ⅱ by the American Society of Anesthesiologists (ASA) and aged 18-70 years were included, including 32 males and 39 females, with a body mass index (BMI) of 18.5-30.0 kg/m2. The patients were randomly divided into three groups: (1) Control group (group C, n=24): continuous intravenous infusion of normal saline at the same rate during surgery; (2) Subanesthetic dose of esketamine 0.125 mg·kg-1·h-1 group (group ES1, n=23): continuous intravenous infusion of esketamine at a rate of 0.125 mg·kg-1·h-1 during surgery; (3) Subanesthetic dose of esketamine 0.250 mg·kg-1·h-1 group (group ES2, n=24): continuous intravenous infusion of esketamine at a rate of 0.250 mg·kg-1·h-1 during surgery. The main outcome measures were the total consumptions of hydromorphone of 3 groups within 24 and 48 hours after surgery. The secondary outcome measures were the extubation time, length of postanesthesia care unit (PACU) stay, the time of first feeding, and the incidences of adverse effects within 24 h after surgery in 3 groups. Results: The 24 h postoperative consumption of hydromorphone in group C, ES1 and ES2 was (5.4±1.0) mg, (4.5±1.5) mg and (4.0±0.8) mg, respectively. Likewise, the 48 h postoperative consumption of hydromorphone was (9.7±2.2) mg, (9.0±3.0) mg and (7.7±1.8) mg, respectively. Compared with group C, the 24 h postoperative hydromorphone consumptions were significantly reduced in group ES1 and ES2 (both P<0.05). The extubation time, length of PACU stay and the time of first feeding after surgery in group C were (23±10) min,(70±12) min,(17±3) h,in group ES1 were (22±4) min,(69±11) min,(14±5) h,in group ES2 were (16±8) min,(58±12) min,(14±3) h, respectively. Compared with group C and group ES1, both of the extubation time and length of PACU stay were shortened in group ES2 (both P<0.05). Compared with group C, the first postoperative feeding time of group ES1 and ES2 was shortened (both P<0.05). There were no differences in the incidences of adverse effects at postoperative 24 h among 3 groups (all P>0.05). Conclusion: Continuously intravenous infusion of subanesthetic esketamine at a rate of 0.250 mg·kg-1·h-1 can significantly reduce the postoperative opioid consumption and improve the patient's outcomes.

Abstract
Objective: To explore the association between occupational noise exposure and cardiovascular disease (CVD) risk in a large Chinese population. Methods: In December 2019, the study included 21412 retired participants from the Dongfeng-Tongji Cohort Study at baseline from September 2008 to June 2010, occupational noise exposure was evaluated through workplace noise level and/or the job titles. In a subsample of 8931 subjects, bilateral hearing loss was defined as a pure-tone mean of 25 dB or higher at 0.5, 1 , 2, and 4 kHz in both ears. Logistic regression models were used to explore the association of occupational noise exposure, bilateral hearing loss with 10-year CVD risk. Results: Compared with participants without occupational noise exposure, the 10-year CVD risk was significantly higher for noise exposure duration ≥20 years (OR=1.20, 95%CI:1.01-1.41 , P=0.001) after adjusting for potential confounders. In the sex-specific analysis, the association was only statistically significant in males (OR=2.34, 95%CI: 1.18-4.66, P<0.001) , but not in females (OR=1.15, 95%CI:0.97-1.37, P=0.153). In the subsample analyses, bilateral hearing loss, which was an indicator for exposure to loud noise, was also associated with a higher risk of 10-year CVD (OR= 1.17, 95% CI:1.05-1.44, P <0.001) , especially for participants who were males (OR =1.24, 95% CI:1.07-2.30, P<0.001) , aged equal and over 60 years old (OR=2.30, 95%CI: 1.84-2.88, P<0.001) , and exposed to occupational noise (OR=1.66, 95%CI: 1.02-2.70, P=0.001). Conclusion: Occupational noise exposure may be a risk factor for CVD.

Abstract
Primary hepatocellular carcinoma is one of the most common high-grade malignant tumors in the world. Its incidence ranks fifth among malignant tumors in China, and various therapeutic measures have poor curative effect. Pyruvate kinase type M2 is a key enzyme in the glycolytic pathway, and its abnormal expression in liver cancer is closely related to the proliferation, metastasis, diagnosis, treatment, prognosis, as well as drug and radiation resistance. Therefore, multi-pathway targeted regulation of pyruvate kinase type M2 use is expected to become a new direction for the treatment of primary liver cancer.

Abstract
Three patients diagnosed with focal cortical dysplasia (FCD) in the First Hospital of Peking University from September to November 2020 were recruited in the study. Based on stereotactic electroencephalogram (SEEG) or electrocorticogram (ECoG) analysis to localize the seizure onset zone (SOZ), RNA sequencing (RNA-seq) analysis was performed for the SOZ and para-SOZ tissue obtained from surgery. The differentially expressed genes between SOZ and para-SOZ samples were analyzed by performing Go (Gene ontology) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis."Extracellular matrix"was significantly enriched, which included collagen synthesis genes (e.g., COL1A1)."Ether lipid metabolism"was enriched in the KEGG pathway enrichment analysis. These differences could be the potential biological markers for SOZ localization.

Abstract
Objective: To investigation the situation of occupational noise exposure and hearing loss among workers in automobile manufacturing enterprise during 2017-2019 in Wuhan. Methods: Workers in automobile manufacturing who underwent physical examination in Wuhan Hospital for the Prevention and Treatment of Occupational Diseases from 2017 to 2019 were included as subjects in the cross-sectional survey. Questionnaire survey, noise detection and pure tone threshold test were used. Excluding individuals with working time less than 3 years and information deficiency, 3 948 individuals were finally included in the study. Results: Among 3 948 workers, 128 workers had hearing loss and the rate of hearing loss was 3.24%, among which 101 workers had high-frequency hearing loss and 27 workers were diagnosed as occupational noise deafness. The prevalence of hearing loss among workers previously exposed to noise was significantly higher than that without prior exposure (12.10%, 0.96%, P<0.05) . The prevalence of hearing loss among workers with occupational noise exposure <80 dB (A) , 80~<85 dB (A) and ≥85 dB (A) was 1.83%, 2.69% and 5.09%, respectively. The prevalence of high frequency hearing loss was 1.60%, 2.05% and 3.71%, respectively. The prevalence of occupational noise deafness was 0.23%, 0.64% and 1.38%, respectively. The prevalence of hearing loss and high frequency hearing loss among workers exposed to different occupational noise was statistically significant (P<0.05) , while the prevalence of occupational noise deafness was not statistically significant (P>0.05) . There were statistically significant differences in the prevalence of hearing loss (2.88%, 4.45%) and occupational noise deafness (0.46%, 1.41%) between those who used protective equipment and those who did not (P<0.05) . Compared with workers exposed to occupational noise <80 dB (A) , workers exposed to occupational noise ≥85 dB (A) had A 3.16-fold increased risk of hearing loss (OR=3.16, 95%CI: 1.44~6.95, P<0.05) . Compared to workers using hearing protective equipment, the risk of hearing loss (OR=1.96, 95%CI: 1.25~3.06, P<0.05) and occupational noise deafness (OR=3.46, 95%CI: 1.51-7.96, P<0.05) significantly increased among those without using hearing protective equipment. Conclusion: The risk of hearing loss in automobile manufacturing workers is significantly associated with occupational noise exposure and the use of hearing protective equipment. Good hearing protection may reduce the risk of occupational noise-induced hearing loss and occupational noise deafness.

Abstract
Occupational noise is one of the most common occupational hazards in the workplace. Long-term exposure to occupational noise could not only lead to the damage of the hearing system, but also may cause a certain impact on the cardiovascular system. Studies have shown that occupational noise exposure was positively associated with cardiovascular diseases, including hypertension, coronary heart disease and myocardial infarction. However, the results of studies on occupational noise exposure and stroke are still controversial. This paper reviews the relationship between occupational noise exposure and hypertension, coronary heart disease, stroke, myocardial infarction by summarizing the epidemiological data of domestic and foreign population in recent years. Our study could provide evidence for the design and implementation of well-designed epidemiological and mechanism studies, and the recognition of the role of occupational noise exposure in the occurrence and development of cardiovascular diseases, so as to better protect workers' health.

Abstract
Chromium may regulate dairy cow metabolism; a chelated formation of chromium methionine (Cr-Met) is available to the feed industry. The objective of this study was to investigate the effect of Cr-Met supplementation on lactation performance, hepatic respiratory rate and anti-oxidative capacity in early-lactating Holstein dairy cows. 64 multiparous cows were assigned to 16 blocks based on parity and milk yield and then the four cows in a block were randomly allocated to four treatment groups with 0, 4, 8 or 16 g/d of Cr-Met per cow supplemented to a basal diet. Cows were moved from an open dry lot to a naturally ventilated tie stall barn 2 weeks before treatment to adapt to this facility, fed and milked at 0630, 1400, and 1930 h every day. The experiment lasted for 12 weeks. Milk yield and composition were recorded weekly. Dry matter intake was measured every 2 weeks for a total of six times throughout the trial. The plasma variables were measured in weeks 4, 8 and 12 of the experiment. Supplementation of Cr-Met did not affect DM intake of cows. As the supplementation of Cr-Met increased, yields of milk, fat, energy corrected milk (P < 0.01) and lactose (P = 0.01) increased in a linear manner. In terms of plasma variables, insulin concentration decreased in a linear manner with Cr-Met supplementation. As for variables relating to hepatic respiration rate, concentrations of pyruvate and NAD in the plasma were increased in quadratic manners, and lactic dehydrogenase activity was linearly increased as Cr-Met feeding levels increased. Moreover, plasma glutathione peroxidase and superoxide dismutase activity were increased in a linear manner. In conclusion, our study suggested that Cr-Met supplementation improved lactation performance of early-lactating dairy cows through enhancing antioxidant capacity and hepatic cellular respiration.

Abstract
The aim of this study was to investigate the effect of micro ribonucleic acid (miR)-195 on myocardial infarction (MI) in rats via regulating the transforming growth factor-β1 (TGF-β1)/Smad signaling pathway. A total of 36 Sprague-Dawley rats were randomly divided into a normal group (n=12), a model group (n=12) and an miR-195 antagomir group (n=12). In the normal group, the heart was exposed only, and normal saline was intraperitoneally injected after operation. In the model group, the acute MI model was established. In the miR-195 antagomir group, the acute MI model was also established, and miR- 195 antagomir was intraperitoneally injected. The samples were collected at 2 weeks after surgery. Then cardiac function was detected via echocardiography, and the morphology of heart tissues was observed via hematoxylin and eosin (H&E) staining. Moreover, the expression of Collagen I was determined using immunohistochemistry, the protein expressions of TGF-β1, Smad3 and Smad7 were detected using Western blotting, and the expression of miR-195 was detected via quantitative polymerase chain reaction (qPCR). It was found by echocardiography that, compared with those in the normal group, left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) significantly declined, while left ventricular end-diastolic diameter (LVDd) and left ventricular end-systolic diameter (LVDs) significantly rose in the other two groups (P<0.05). In comparison with the model group, the miR-195 antagomir group had significantly increased LVEF and LVFS, and significantly decreased LVDd and LVDs (P<0.05). The immunohistochemistry results showed that the mean optical density of tissues with positively expressed Collagen I was obviously higher in the other two groups than that in the normal group (P<0.05), while it was obviously lower in the miR-195 antagomir group than that in the model group (P<0.05). According to the results of Western blotting, the protein expressions of TGF-β1 and Smad3 were evidently increased, while the protein expression of Smad7 was evidently decreased in the other two groups compared with those in the normal group (P<0.05). The opposite results were found in the miR-195 antagomir group compared with those in the model group (P<0.05). The results of qPCR manifested that the expression of miR-195 was markedly higher in the other two groups than that in the normal group (P<0.05), while it was markedly lower in the miR-195 antagomir group than in the model group (P<0.05). Moreover, it was observed using H&E staining that the myocardial fibers in the normal group had normal arrangement and intact structure, without obvious morphological abnormalities. In the model group, the myocardial fibers were arranged disorderly, and there were massive proliferating fibrous tissues, with a high degree of fibrosis. In themiR-195 antagomir group, the myocardial fibers were damaged and arranged less disorderly, and proliferation and fibrosis could be seen in some fibrous tissues, but to a lesser extent than the model group. In conclusion, miR-195 promotes myocardial fibrosis in MI rats via up-regulating the TGF-β1/Smad signaling pathway.

Abstract
OBJECTIVE To investigate whether microRNA-489 could promote cardiomyocyte apoptosis through targeting inhibition of SPIN1, thus participating in the development of myocardial ischemia-reperfusion injury. MATERIALS AND METHODS MicroRNA-489 expression in H9c2 cells induced with hypoxia/reoxygenation (H/R) was determined by quantitative real-time polymerase chain reaction (qRT-PCR). With microRNA-489 overexpression in H/R H9c2 cells, activities of lactate dehydrogenase (LDH), methane dicarboxylic aldehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) were detected using relative commercial kits, respectively. The regulatory effect of microRNA-489 on the proliferation and apoptosis of H/R H9c2 cells was assessed through cell counting kit-8 (CCK-8) assay and flow cytometry (FCM), respectively. Through conducting a dual-luciferase reporter gene assay, we evaluated the binding condition between microRNA-489 and SPIN1. Protein expressions of apoptotic genes in H/R H9c2 cells with microRNA-489 overexpression were determined by Western blot. Finally, the regulatory role of microRNA-489 in PI3K/AKT pathway was detected through Western blot. RESULTS QRT-PCR data showed that microRNA-489 was highly expressed in H/R H9c2 cells than those in normoxic control. Overexpression of microRNA-489 in H/R H9c2 cells increased the activities of LDH, MDA and GSH-PX, while decreased the activities of SOD. MicroRNA-489 overexpression markedly inhibited the proliferative rate but accelerated apoptosis of H/R H9c2 cells. Western blot results indicated that protein expressions of pro-apoptotic genes Bax and cytochrome C upregulated, whereas anti-apoptotic gene Bcl-2 downregulated after overexpression of microRNA-489 in H/R H9c2 cells. We confirmed that microRNA-489 could target to SPIN1 and inhibit its expression. After overexpression of microRNA-489 in H/R H9c2 cells, PI3K/AKT pathway was inhibited, which was further reversed by PI3K/AKT pathway agonist SC79. Besides, SC79 treatment also reversed the regulatory effect of overexpressed microRNA-489 on cellular behaviors of H/R H9c2 cells. CONCLUSIONS MicroRNA-489 inhibits the proliferation and accelerates apoptosis of cardiomyocytes after MIRI by targeting inhibition of SPIN1 via inactivating PI3K/AKT pathway. MicroRNA-489 may be a potential therapeutic target for MIRI.

Abstract
OBJECTIVE Triple-negative breast cancer (TNBC) is an aggressive type of breast cancer. Long noncoding RNAs (lncRNAs) have been reported to be involved in the development of TNBC. However, the role and mechanism of LINC01096 in TNBC are largely unclear. This work aims to investigate the effect of LINC01096 on cell viability, apoptosis, migration, and invasion of TNBC cells, as well as explore the interaction between LINC01096 and microRNA (miR)-3130-3p. PATIENTS AND METHODS Sixty TNBC patients were recruited. T47-D and BT-549 cells were cultured for experiments in vitro. The expression levels of LINC01096 and miR-3130-3p were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Cell viability, apoptosis, migration, and invasion were determined by MTT, flow cytometry, and trans-well assays. The target association between LINC01096 and miR-3130-3p was confirmed by the luciferase reporter assay. RESULTS The expression of LINC01096 was enhanced in TNBC tissues and cells. High expression of LINC01096 predicted poor outcomes of patients with TNBC. Silence of LINC01096 led to the suppression of cell viability, migration, and invasion, as well as the promotion of apoptosis in TNBC cells. MiR-3130-3p was targeted by LINC01096 and lowly expressed in TNBC. Overexpression of miR-3130-3p repressed cell viability, migration, and invasion, while it induced apoptosis. However, the knockdown of miR-3130-3p induced the opposite effect. This was weakened by inhibiting LINC01096. CONCLUSIONS Knockdown of LINC01096 inhibited cell viability, migration, and invasion; however, it promoted apoptosis in TNBC by up-regulating miR-3130-3p, indicating a novel target for the treatment of TNBC.

Abstract
Objective: To analyze the heritability of coronary heart disease (CHD) among the Chinese twin adults. Methods: A total of 20 477 same-sex twin pairs aged 25 years and older from the Chinese National Twin Registry were interviewed. Structure equation model was used to estimate the heritability of CHD. Results: After adjusting for age and gender, the overall heritability of CHD was 0.75(0.68-0.81). Stratified analyses showed that genetic factors play a more important role in CHD incidence in ≥40 years or female twins. While the development of CHD was mainly influenced by environmental factors in 25-39 years or male twins. Conclusion: CHD is influenced by both genetic and environmental factors and the heritability is high.

Abstract
N-Carbamoylglutamate (NCG) is an enhancer of Arg, which is a functional AA and could prevent cardiovascular disease and improve immunity. The present study was conducted to investigate the effects of supplementing NCG in diets of lactating cattle on the NCG concentration and AA composition of raw milk and on mozzarella cheese quality. Thirty multiparous cows with a mean body weight of 669 kg (standard deviation = 71) and days in milk of 176 (standard deviation = 55) were blocked based on parity and milk production and randomly assigned to 1 of 2 treatments: basal diet (CON) and basal diet supplemented with 40 g of NCG per day per cow (NCG). After 8 wk of treatment, raw milk samples were collected from the 2 groups for AA analysis and mozzarella cheese-making. Furthermore, the NCG concentration and distribution in milk and mozzarella cheese were detected. The AA concentration in milk was greater and the NCG concentration in raw milk was approximately 6 times greater in the NCG group than in the CON group. No NCG was detected in cheese from the CON group, and very little NCG (<1.0 μg/kg) of cheese was detected in the NCG group. Most of the dietary NCG was transferred into whey, stretch water, and brine during cheese production. No significant difference was found between the 2 groups on cheese texture and color except that hardness was lower in the NCG group. Overall, the results indicated that dietary supplementation of NCG could improve the NCG and AA concentrations in raw milk without affecting the quality of cheeses such as mozzarella.

Abstract
OBJECTIVE To investigate whether lncRNA H19 can regulate NF1 expression through competitive binding to microRNA-107, thereby participating in the occurrence and development of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Expression levels of H19 and NF1 in NSCLC tissues, paracancerous tissues and NSCLC cell lines were detected by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). The binding condition of microRNA-107, H19 and NF1 was detected by dual-luciferase reporter gene assay. Corresponding lentiviruses of H19 were constructed. The regulatory effects of H19 on proliferative and migratory abilities of A549 cells were detected by cell counting kit-8 (CCK-8) and transwell assay, respectively. Rescue experiments were conducted to explore the regulatory interaction between H19 and microRNA-107 in A549 cells. RESULTS H19 and NF1 were highly expressed in NSCLC tissues and NSCLC cell lines (A549 and HCC823) than those of controls. Overexpressed H19 increased proliferative and migratory abilities of A549 cells. Dual-luciferase reporter gene assay demonstrated that H19 regulates NF1 expression through competitive binding to microRNA-107, thereafter participating in NSCLC development. CONCLUSIONS H19 is highly expressed in NSCLC, which promotes NSCLC development by regulating NF1 via competitive binding to microRNA-107.

Abstract
Objective:To explore the relationships between trefoil factor 3(TFF3) gene polymorphisms and susceptibility to papillary thyroid carcinoma(PTC) in Han population of northern China. Method:A case-control study was performed in 123 PTC patients and 108 healthy controls. Four SNPs in the TFF3 gene, including rs225361, rs533093, rs9981660 and rs225439, were detected by gene sequencing. Result:Compared with healthy people, there was no significant difference in the genotype frequencies of rs225361, rs9981660, rs533093 and rs225439 alleles in the PTC group(P>0.05). The CGTC and CGTT haploids of TFF3 gene were positively correlated with the occurrence of PTC, and CGCC and TGTC haploids were negatively correlated with the occurrence of PTC. TT genotype of rs9981660 had significant differences in the distribution of PTC with and without lymph node metastasis(P<0.05). Conclusion:Polymorphisms in 4 SNP loci in the TFF3 gene may be unrelated to the occurrence of PTC. The CGTC, CGTT, CGCC and TGTC haploids in the TFF3 gene might be related to the development of PTC. The TT genotype at rs9981660 may be associated with lymph node metastasis of PTC.

Abstract
AIM To investigate the stress distribution and tooth displacement of a maxillary central incisor with various apical root resection lengths and occlusal relationships using finite element (FE) analysis. METHODOLOGY A maxillary central incisor was scanned by micro-CT. First, the FE intact incisor model with dentine, enamel, pulp and root surrounded by alveolar bone and periodontal ligament was designed based on the micro-CT image data. Then, six FE models with varying lengths of apical root resection were established to simulate the clinical treatment and reveal the clinically applicable limit of apical root resection during endodontic microsurgery. For each model under different loading conditions, the maximum von Mises stress (σ max) at the root apex, root cervix, alveolar bone and periodontal ligament and the maximum tooth displacement (ΔR max) were calculated and compared. RESULTS In a normal occlusion, more than 6 mm of root resection resulted in a marked increase in the ΔR max values (>10%) and σ max values of alveolar bone (>50%); the stress levels at the root apex increased dramatically when the apical root was resected more than 7 mm. With increased overjet, apical root resection did not change the stress level markedly until it reached 8 mm, but the ΔR max increased markedly (>10%) if the root was resected more than 5 mm. With deep overbites, the σ max increased significantly (>50%) when the root was resected more than 4 mm whilst the ΔR max decreased. With increased overjet and deep overbite, more than 6 mm of resection resulted in a substantial σ max increase (>50%) of alveolar bone and the ΔR max increased markedly (>10%) when the root was resected 8 mm. Additionally, the σ max and the ΔR max values were greater with increased overjet and lower with deep overbites. CONCLUSIONS Using FE analysis, apical root resection of more than 6 mm resulted in a marked increase of stress distribution and tooth displacement in normal and increased overjet with deep overbite occlusal relationships. In increased overjets or deep overbites, more than 5 mm or 4 mm, respectively, stress distribution and tooth displacement increased markedly.

Abstract
The current study investigated the effects of hydroxyselenomethionine (HMBSe), a novel organic selenium (Se) additive, on lactation performance, blood profiles, antioxidative status, and transfer efficiency of Se in early-lactation dairy cows. Sixty multiparous early-lactating dairy cows with similar days in milk (57 d; standard deviation = 9.9) and milk yield (36.5 kg/d; standard deviation = 1.42) were fed a basal diet containing 0.04 mg of Se/kg (dry matter basis). These cows were assigned to 1 of 4 groups following a randomized complete block design as follows: control (basal diet) or HMBSe addition (0.1, 0.3, or 0.5 mg of Se/kg of dry matter). The experiment lasted for 13 wk, with the first week as adaptation. The results showed that milk yields (raw, protein, and lactose) and feed efficiency were improved in a quadratic manner following increased dietary HMBSe addition, whereas energy-corrected milk, 4% fat-corrected milk, and total solid yields tended to be enhanced quadratically. In terms of whole-blood variables, red blood cell and white blood cell levels were increased quadratically, whereas hemoglobin concentration increased linearly with increased HMBSe addition. Plasma nonesterified fatty acid concentrations tended to increase linearly along with HMBSe addition. Plasma superoxide dismutase activity increased quadratically with increased HMBSe addition. The total antioxidant capacity in plasma tended to improve quadratically when cows were fed more HMBSe. Moreover, plasma malondialdehyde concentrations of dairy cows tended to decrease in a quadratic manner when dietary HMBSe increased. The Se concentrations in milk, plasma, and milk/plasma ratio increased linearly following increased HMBSe addition. In conclusion, HMBSe improved lactation performance, health status, and milk Se concentrations in early-lactating dairy cows.

Abstract
Objective: To investigate the prevalence and risk factors of neck and shoulder pain (NSP) among automobile manufacturing workers and to provide a theoretical basis for prevention of NSP. Methods: From November 5 to November 19, 2017, a total 446 works who had worked for more than one year were recruited from an automobile plant by cluster sampling method. Chi square test and unconditional logistic regression were used to exam the relation between influencing factors and NSP. Results: The annual prevalence rate of NSP was 34.8%. Multifactor regression analysis showed that age、work fatigue、department staff shortages、lifting heavy objects in awkward positions、neck flexion foreword and prolong sitting position work were the risk factors of NSP (OR=2.18, 95%CI:1.49~3.18; OR=4.52, 95%CI:1.27~16.00; OR=1.66, 95%CI:1.04~26.68; OR=2.10, 95%CI:1.16~3.81; OR=2.25, 95%CI:1.39~3.66; OR=2.42, 95%CI:1.06~5.56) and work break was the benefit factors of NSP (OR=0.58, 95%CI:0.36~0.94) . Conclusion: The annual prevalence rate of NSP among automobile manufacturing workers was high. Lifing heavy objects、awkward working positions and unreasonable work arrangement were the major risk factors of NSP, and work break can effectively reduce the risk of NSP. Effective ergonomic intervention should be carried out to prevent the occurrence of NSP.

Abstract
The objective of current study was to investigate the effect of N-acetyl-l-methionine (NALM) supplementation on lactation performance and plasma variables in mid-lactating dairy cows. Forty-eight multiparous cows were blocked into 12 groups based on parity, days in milk, and milk production and were randomly assigned to 1 of the 4 treatments: 0, 15, 30, or 60 g/d of NALM per cow to supplement the basal diet. The experiment was conducted over a 13-wk period, with the first week as adaptation. The yields of milk, fat-corrected milk, and milk lactose were increased quadratically, and energy-corrected milk yield tended to increase with increased NALM supplementation in a quadratic manner. The dry matter intake, milk protein yield, milk fat yield, contents of milk composition (protein, fat, lactose, total solids, and milk urea nitrogen), feed efficiency, and body weight change were not affected by NALM supplementation. In addition, plasma methionine concentration was increased quadratically, and proline, total nonessential AA, and total AA concentrations were significantly higher in the 30 g/d group compared with that of the control group. However, other AA and total essential AA concentrations were not affected with supplementation of NALM. Adding NALM increased concentrations of total protein and globulin in plasma, but decreased plasma urea nitrogen concentration in a quadratic manner. Meanwhile, plasma malonaldehyde concentration decreased linearly as doses of NALM addition increased. Our results suggested that the supplementation of NALM improved milk yield and protein synthesis in the liver, and lowered lipid peroxidation in mid-lactating dairy cows.

Abstract
Optical chaos communication has advantages of high speed and long transmission distance. Unfortunately, the key space of the traditional transceiver, i.e. semiconductor laser with mirror feedback, is limited due to the time delay signature. In this paper, we propose and numerically demonstrate a key space enhancement by using semiconductor laser with optical feedback from a chirped fiber Bragg grating (FBG). The chirped FBG feedback can make feedback delay a key parameter by eliminating the time delay signature. Moreover, the grating dispersion and center frequency can also be used as new keys. As a result, the dimension of key space is increased. By taking a bidirectional communication scheme as an example, numerical results show that the key space is raised by 244 times as against mirror feedback with a data rate of 2.5 Gb/s and a coupling strength of 0.447. As the coupling strength decreases, the key space increases due to the fact that chaos synchronization becomes more sensitive to parameter mismatch.

Abstract
Starchy grain is usually supplemented to diets containing low-quality forage to provide sufficient energy for ruminant animals. Ruminal degradation of grain starch mainly depends on the hydrolysis of the endosperm, which may be variable among grain sources. This study was conducted to investigate the influence of endosperm structure of wheat and corn on in vitro rumen fermentation and nitrogen (N) utilization of rice straw. The 3×4 factorial design included three ratios of concentrate to forage (35:65, 50:50 and 65:35) and four ratios of wheat to corn starch (20:80, 40:60, 60:40 and 80:20). The endosperm structure was detected by scanning electronic microscopy and a confocal laser scanning microscopic. An in vitro gas test was performed to evaluate the rumen fermentation characteristics and N utilization. Starch granules were embedded in the starch-protein matrix in corn, but more granules were separated from the matrix in the wheat endosperm. With the increasing ratio of wheat, rate and extent of gas production, total volatile fatty acids, and ammonia N increased linearly (P<0.01), but microbial protein concentration decreased (quadratic, P<0.01), with the maximum value at a ratio of 40% wheat. The efficiency of N utilization decreased linearly (P<0.01). Rumen fermentation and N utilization were significantly affected by the concentrate-to-forage ratio (P<0.01). Significant interactions between the concentrate-to-forage ratio and the wheat-to-corn ratio were detected in total volatile fatty acids and the efficiency of N utilization (P<0.01). In summary, the starch-protein matrix and starch granules in the wheat and corn endosperm mixture play an important role in the regulation of rumen fermentation and N utilization under low-quality forage.

Abstract
It is known that women develop alcoholic liver injury more rapidly and have a lower alcohol toxic threshold than men. However, the detailed molecular mechanisms remain unclear. The precise mechanism responsible for the sex difference needs to be determined. Female and male mice were given ethanol by intragastric infusion every day for 4 weeks. The pathological changes were detected by hematoxylin-eosin, Sirius red, oil red O, periodic acid-Schiff, and Hochest33258 staining in the liver of female and male mice. The related gene and protein expression of hepatocytes stress, proliferation and apoptosis, glycogen synthesis, lipid metabolism, and hepatic fibrosis were also systematically analyzed in the female and male mice. Livers from ethanol-treated female mice had more serious hepatocyte necrosis, liver fibrosis ( P < 0.01), substantial micro/macrovesicular steatosis ( p < 0.01), glycogen consumption ( p < 0.05), and hepatocytes apoptosis ( p < 0.05) than ethanol-treated male mice. The expression of heat shock protein 27 (HSP27), HSP70, proliferating cell nuclear antigen, B-cell lymphoma/leukemia-2 (Bcl-2), and phosphorylated signal transducer and activators of transcription 3 (p-STAT3) was higher in ethanol-treated male mice than ethanol-treated female mice ( P < 0.05 or P < 0.01). But, the expression of Bax (Bcl-2-associated X protein), Caspase 3, CYP2E1 (cytochrome P4502E1), and transforming growth factor βl had the contrary results. Our study suggested that ethanol treatment induced more expression of HSP27 and HSP70, faster hepatocyte proliferation, higher level of glycogen, and interleukin-6 signaling pathway activation, but less hepatocyte apoptosis and CYP2E1 expression in male mice than female mice, which could be helpful to understand the molecular mechanism for the influence of sex difference on alcoholic liver injury.

Abstract
Objective: To investigate the influence of coke oven emissions on workers' blood pressure and electrocardiographic findings, and to provide a basis for the prevention and treatment of cardiovascular diseases. Methods: The concentration of coke oven emissions at the bottom, side, and top of coke ovens was determined in a coking plant. A total of 406 coke oven workers were enrolled as exposure group and 201 office staff members were enrolled as control group. Blood pressure and electrocardiographic findings were compared between the two groups, and the multivariate logistic regression analysis was performed to analyze the influencing factors for hypertension and abnormal electrocardiographic findings. Results: The concentration of coke oven emissions was the highest at the top of coke ovens, followed by the side and bottom of coke ovens, and there was a significant difference between the exposure group and the control group (P<0.01). The exposure group had significantly higher detection rates of hypertension, abnormal electrocardiographic findings, and abnormal chest X-ray findings than the control group (P<0.05). The logistic regression analysis showed that high concentration of coke oven emission and age were risk factors for hypertension and abnormal electrocardiographic findings (P<0.05). The workers exposed to high-concentration coke oven emissions were more likely to experience hypertension and abnormal electrocardiographic findings than those exposed to low-concentration coke oven emissions (OR=1.7 and 1.9). Conclusion: Besides lung injury, coke oven emissions also have adverse effects on the cardiovascular system. Therefore, more effective measures are needed to protect the health of coke oven workers.

Abstract
OBJECTIVE Endometrial cancer is one of the three most common types of gynecologic cancer. The global incidence has increased in recent years. microRNAs (miRNAs) regulate numerous biological processes by binding to the 3'UTR of target mRNA to down-regulate protein synthesis. PATIENTS AND METHODS Endometrial cancer patients received surgeries in our hospital were enrolled. MiR-15a-5p mimic or miR-15a-5p inhibitor was transfected into HEC-1-A cells by lentivirus. Colony formation assay was applied for detecting cell proliferation. Real-time PCR was performed to test miRNA and mRNA expression. Western blot was used to detect protein level. ChIP was adopted to test transcription activation. TOP/FOP was tested to determine Wnt signaling pathway activity. A dual-luciferase reporter assay was used to confirm miRNA target. RESULTS miR-15a-5p was decreased in endometrial cancer cells and tissues. miR-15a-5p overexpression restrained HEC-1-A cell proliferation and stemness. miR-15a-5p mimic transfection reduced mRNA and protein levels of the proteins which are related to cell proliferation and Wnt signaling pathway. MiR-15a-5p targeted a putative binding site in the 3'-UTR of Wnt3a gene, thus regulating Wnt signaling pathway. miR-15a-5p overexpression decreased Wnt3a protein expression. Wnt3a presented significant negative correlation with the miR-15a-5p level in endometrial cancer patients. CONCLUSIONS miR-15a-5p is a regulator of endometrial cancer cell proliferation by directly targeting Wnt3a to block Wnt signaling pathway.

Abstract
Objective: To analyze the infection and drug resistance of extrapulmonary tuberculosis, in order to provide useful references for prevention and treatment of tuberculosis (TB). Methods: A total of 6 107 suspected cases of extrapulmonary tuberculosis, including lymph node, pleural, peritoneal, meningeal, urinary tract, and bone tuberculosis, were collected retrospectively from January 2013 to December 2015 in Public Health Clinical Center of Chengdu. There were 4 033 male and 2 074 female patients, and the average age was 37 years.The epidemiological data, infection and drug resistance were analyzed statistically. Results: There were 21 036 cases of mycobacterial culture from January 2013 to December 2015, of which 7 119 were positive(33.8%). Extrapulmonary tuberculosis was found in 6 107 cases, of which 896 were positive, accounting for 12.6% of the positive cases(896/7 119). Culture-positive cases of extra-pulmonary tuberculosis showed a rising trend from 2013 to 2015 (n=174, 310, 421, respectively), and the annual average increasing rate was over 50%.Cases were distributed at younger ages (21-40 years), with an average age of 34 years.There were more male patients, with a male to female ratio of 2.1∶1. The most common site of extrapulmonary tuberculosis was the bone(62/243, 25.5%), followed by lymph node(283/1 297, 21.8%), pleural(289/1 840, 15.7%), urinary tract(63/452, 13.9%), peritoneum(41/303, 13.5%), meningeal(156/1 915, 8.1%)and other types of tuberculosis(2/57, 3.5%). Drug sensitivity test of 896 extrapulmonary tuberculosis strains showed that the resistance rate (from high to low) was in the order of isoniazid, rifampicin, streptomycin, ofloxacin, ciprofloxacin, amikacin, capreomycin and ethambutol. Multidrug-resistant(MDR)and extremely-drug resistant (XDR) rate was 9.7 %(87/896)and 2.0%(17/896)respectively. Conclusions: Cases of extrapulmonary tuberculosis sent for bacterial culture and the positive rate showed a rising trend by years in Chengdu area.The drug resistance level was higher than that reported both in China and abroad.The prevention and treatment of extrapulmonary tuberculosis should be strengthened in this area.

Abstract
Some studies assessed the association between lncRNA taurine-upregulated gene 1 (TUG1) and the survival in cancer. However, the results were inconclusive. Therefore, we performed a meta-analysis to determine this association. We used the following electronic databases to search for eligible literature: PubMed, Embase, Chinese National Knowledge Infrastructure (CNKI) and Wanfang. We used ORs and 95% CIs to measure the association between TUG1 and the survival of cancer. There was no significant association between TUG1 and OS of cancer (HR=1.26, 95% CI=0.97-1.64). In the subgroup analysis by cancer type, significant association could be find in osteosarcoma (HR=1.72, 95% CI=1.27-2.32) and digestive system's tumors (HR=1.66, 95% CI=1.04-2.66). In conclusion, this meta-analysis study indicated that TUG1 might associate with the OS of osteosarcoma and digestive system's tumors.

Abstract
Objective: To investigate the characteristics of superior petrosal vein (SPV) and its influence on the surgical field in microvascular decompression (MVD) for trigeminal neuralgia (TN), and to analyze the effect of the surgical treatment of SPV on the surgical approach, indication and prognosis. Methods: The clinical data of 280 patients with trigeminal neuralgia between Jan. 2013 and Jun. 2016 were collected, including the trunks and the branches of SPV, intraoperative electrocoagulation status, the surgery outcome and complications. Results: The petrosal vein during the operation was fully preserved in 152 cases (54.29%). The SPV were completely sectioned in 25 cases (8.92%), while some branches of SPV were sectioned in 103 cases (36.79%). We found that SPV have 1 to 3 trunks, accounted for 67 cases (23.90%), 168 cases (60%), and 45 cases (16.10%), while the SPV with 1 to 4 branches accounted for 17 cases (6.07%), 112 cases (40%), 136 cases (48.57%), and 15 cases (5.36%). The SPV was identified as offending vessel in 17 cases (6.07%). One patient with cutoff SPV trunk encountered cerebellar infarction and recovered completely at 2 weeks after MVD by using intravenous medication. Conclusions: MVD is the recommended treatment method for PTN, mostly SPV is unnecessary to be sectioned completely and small branches of SPV could be sacrificed. Very few patients may develop cerebellar infarction or hematoma.

Abstract
Objective:Experiments testing the concentration of serum E-cadherin were conducted through the patients with papillary thyroid carcinoma (PTC), nodular goiter and normal people. Combining the detection of E-cadherin protein in the tissues including papillary thyroid carcinoma,nodular goiter and normal thyroid tissues around adenoma,we analyze the effect and siginificance of E-cadherin in the papillary thyroid carcinoma.Method:The concentrations of E-cadherin in the serum of 86 cases of PTC patients, 16 cases of NG patients and 10 normal adults were detected by enzyme linked immunosorbent assay (ELISA) method, and the relationships between the serum level and clinical pathology characteristics of thyroid papillary carcinoma were explored. Western blot were used to detect the content of E-cadherin protein in tissues including PTC, nodular goiter tissues and normal thyroid tissues around adenoma.Result:The results showed that content of serum E-cadherin in PTC were significantly higher than those in nodular goiter tissues and normal thyroid issues (P< 0.05). There were no obviously differences between nodular goiter tissues and normal thyroid issues in the content of E-cadherin (P> 0.05). The content of E-cadherin protein in the tissues of PTC was evidently lower than those in nodular goiter tissues and normal thyroid tissues around adenoma (P< 0.05). There were no obviously differences between nodular goiter tissues and normal thyroid tissues around adenoma in the content of E-cadherin (P> 0.05). The abnormal expression of serum E-cadherin was correlated with the lymph node metastasis and pathological stage of PTC (P< 0.05). On the other hand,it is irrelevant to the gender、age and the tumor size of the patients (P> 0.05).Conclusion:The up-regulation of serum E-cadherin is correlated with the lymph node metastasis and pathological stage of PTC. The detection of the serum E-cadherin content plays a vital role in the aspects of early diagnosis and prognosis evaluation.

Abstract
UNLABELLED 3ummary Objective: The aim of this study was to investigate the changes and clinical values of platelet parameters in different types of severe preeclampsia (SP). MATERIALS AND METHODS The pregnant women with SP or normal conditions were selected for the study, the platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW). and plateletcrit (PCT) were tested every four weeks, starting from 12(+1) to 16 gestational weeks, to compare the difference in platelet parameters between SP and normal pregnant women. RESULTS PLT, MPV, and PDW of the early onset group exhibited statistically significant differences than the normal group from 20(+1) gestational weeks, and PCT of the early onset group exhibited statistically significant differences than the normal group from 28(+1) gestational weeks (p < 0.05); PLT, MPV, and PDW of the late onset group exhibited statistically significant differences than the normal group (p < 0.05), while PCT of the late onset group exhibited no statistically significant difference than the normal group from 12(+1) gestational weeks until childbirth (p > 0.05). The comparison between the early onset group and the late onset group revealed that there existed statistically significant differences in PLT, MPV, and PDW (p < 0.05), but PCT showed no statistically significant difference throughout the pregnancy period (p < 0.05). CONCLUSIONS The changes of platelet parameters in early onset SP patients were earlier than the late onset group, and the difference was statistically significant (p < 0.05). Measuring the platelet parameters could better reveal early-stage SP, thus guiding more personalized clinical treatments to better protect maternal and child safety.

Abstract
Objective: To investigate the effect and mechanism of intermedin (IMD)on the apoptosis of BMSCs induced by H2O2 and its mechanism. Methods: BMSCs being cultured in vitro. After 30 min pretreatment with 10-6mol/L IMD, cells were cultured in presence of 100 μmol/L H2O2 for 2 hour, cell apoptosis was determined by flow cytometry; Apoptosis related protein expression was determined by Western blotting and immunofluorescence; Protein and phosphorylation of ERK1/2 was detected by Western blotting and observe the influence of IMD after pretreatment with inhibitor of ERK1/2. Results: IMD could increase phosphorylation of ERK1/2 pathway of BMSCs (P<0.01). Pretreatment of IMD could decrease BMSCs apoptosis induced by H2O2, and up regulation expression of Caspase-3 and Bax, down regulation expression of Bcl-2 (P<0.01), and the effect was abrogated by U0126. Conclusion: IMD can activate ERK1/2 signaling pathway of BMSCs, and can regulate the expression of apoptosis related proteins. Furthermore, it can protect BMSCs from apoptosis induced by H2O2. Activation of ERK1/2 pathway was involved in the effect of IMD on apoptosis.

Abstract
OBJECTIVE Endoplasmic reticulum (ER) stress plays an important role in ischemia-mediated cell death. The aim of the current study is to investigate the effects of salubrinal (Sal), a selective eIF2a dephosphorylation inhibitor, on heart failure rats and related mechanisms. METHODS Heart failure was induced by coronary artery ligation (MI) in adult male Sprague-Dawley rats. To ensure comparable MI sizes post coronary artery ligation on various groups, echocardiography examination was performed before and 30 minutes after ligation in MI groups. Then rats were randomly assigned to 4 groups: Sham group (n=12), MI group (n=10), MI plus vehicle injections group (DMSO group, n=12) and MI plus Sal injection group (Sal group, n=12). Sal (1 mg/kg) or DMSO was injected via the tail vein daily for the first 3 days (starting at 30 minutes after ligation of the left coronary artery), followed by subcutaneous injections twice per week for 8 weeks. Cardiac function was assessed by echocardiography and cell apoptosis assessed by flow cytometric analysis after 8 weeks. Protein and mRNA levels of ER stress markers were evaluated by immunohistochemistry and real time RT-PCR respectively. RESULTS Eight weeks later, LVEF was significantly higher, while LVESD and LVEDD values were significantly lower in Sal group compared to MI and DMSO groups (all P<0.05); LV/BW ratio was significantly higher in MI group than in Sham group ((2.30±0.40) mg/g vs.(1.78±0.31) mg/g, P<0.05), which was significantly reduced in Sal group ((1.88±0.25) mg/g), but not in DMSO group((2.25±0.36) mg/g, P<0.05 vs. MI). In addition, flow cytometric analysis showed that Sal treatment significantly reduced apoptosis but not necrosis in post MI. Immunohistochemistry and real time PCR analysis showed that the myocardial protein and mRNA expression of ER stress markers were significantly lower in Sal group than in MI group, myocardial caspase-12 expression was significantly upregulated in MI group and significantly reduced by Sal treatment. CONCLUSIONS Our results suggest that reduction of ER stress and myocardial apoptosis through inhibition of eIF2α dephosphorylation may serve as the potential mechanisms for the improved cardiac function and attenuated cardiac remodeling post Sal treatment in this heart failure rat model.

Abstract
Some studies investigated the association between ADD1 rs4963 polymorphism and hypertension risk. However, the results remained inconclusive. Thus, we performed a meta-analysis. Published reports were searched in PubMed and Google Scholar. The strength of association was assessed by calculating odds ratios (OR) and 95% confidence interval (CI). Twelve studies with 5097 cases and 5937 controls were conducted in this study. Individuals with ADD1 rs4963 polymorphism showed an increased hypertension risk (OR = 1.21; 95%CI, 1.11-1.33; P < 0.0001). Subgroup analyses were performed according to country and age. The results showed that Chinese with ADD1 rs4963 polymorphism showed an increased hypertension risk (OR = 1.28; 95%CI, 1.09-1.51; P = 0.003). However, subjects in Japan and India did not have increased hypertension risk. In the subgroup analysis by age, older subjects, but not younger subjects, with ADD1 rs4963 polymorphism showed an increased hypertension risk (OR = 1.19; 95%CI, 1.07-1.32; P = 0.001). In conclusion, this meta-analysis suggested that ADD1 rs4963 polymorphism might be associated with increased hypertension risk.

Abstract
Objective: To analyze long-term mortality and patients characteristics of cardiac resynchronization therapy (CRT) for patients with chronic heart failure. Methods: In-patients with chronic heart failure who received CRT in the three medical centers(Bethune International Peace Hospital, General Hospital of Shenyang Military Command of Chinese People's Liberation Army, and 251 Hospital of People's Liberation Army)from March 2001 to June 2013 were included.Mortality and related causes, echocardiographic parameters were analyzed. Results: A total of 200 patients were treated with CRT therapy (154 males, mean age (60.57±11.75) years), 59 cases suffered from ischemic cardiomyopathy (ICM), patients were followed up from 0.5 to 12 years.The all-cause mortality rate was 25.50% (51/200), 20 out of 59 (33.90%) ICM patients died, as compared with 31 deaths out of 141 (21.98%) in non-ischemic cardiomyopath (NICM) patients.Thirty-six patients died due to cardiac death (70.59%), in which sudden death occurred in 21 patients (41.18%). Non-cardiac death occurred in 13 patients (25.49%), two patients died due to unknown reasons (3.92%). Incidence of cardiac death was significantly higher than non-cardiac death (P<0.01). The main cause for cardiac death was NICM (28/36, 77.78%), while the main cause of non-cardiac death was ICM (11/13, 84.62%, P<0.01). Patients died due to cardiac death were younger (P<0.01) and had larger left atrial end-diastolic diameter (LAEDD) and left ventricular end-diastolic diameter (LVEDD) (P<0.01), lower left ventricular ejection fraction (LVEF)(P<0.05), higher pulmonary artery pressure(P<0.05) compared to patients with non-cardiac death.One hundred and fifty-two cases received CRT-P and 48 cases received CRT-D, there were no significant differences in gender, the course of heart failure, serum creatinine levels, pre-operative and post-operative QRS duration and so on between the CRT-P and CRT-D groups(all P>0.05). Eleven out of the 48 cases with CRT-D died during the following-up (21.57%) , while 40 out of 152 cases with CRT-P died (78.43%) during the following-up(χ2=3.13, P<0.01). The proportional mortality rate in cause of death in patients with CRT-D was non-cardiac while in those with CRT-P was cardiac (χ2=2.66, P<0.01), sudden death rate was also significantly higher in CRT-P group than in CRT-D group (χ2=2.16, P<0.01). By using single- and multiple-factor Cox regression analysis, age, disease course, pre-operation QRS duration and NYHA classification were predictors of cardiac death(all P<0.05). Conclusions: The all-cause mortality of CRT is 25.50% in this patient cohort, mortality rate was higher in ICM patients than in NICM patients.Sudden cardiac death rate was the highest mortality reason.The mortality rate of patients with CRT-P was significantly higher than in patients with CRT-D.In comparison with patients of non-cardiac death, patients of cardiac death had larger left atrium and left ventricle and worse heart function before CRT implantation.

Abstract
PURPOSE This study was conducted to investigate the feasibility and clinical potential of using the 3D printing technology (3DPT) versus typical strategy (thin-layer CT scan) for the treatment of complicated proximal humeral fractures (PHFs) in old people. METHODS Sixty-six old patients age ranging from 61 to 76 years with persistent complicated PHFs were randomly assigned to two groups as per the controlled randomization table (34 cases in the test group and 32 cases in the control group). In the test group, 3DPT was applied to build the 3D facture model of a patient, according to the data acquired from the thin-layer CT scan and subsequently processed with Mimics software. This helped to confirm the diagnosis, design the individual operation plan, simulate the surgical procedures and perform the surgery as plan. In the control group, only thin-layer CT scan was applied for the design of the operation plan prior to the surgery. Here, parameters including surgery duration, blood loss volume during surgery, the number of fluoroscopy, time to union were statistically analyzed for two groups after the operation. The screw lengths designed before the surgery and measured during the surgery were compared. RESULTS The 3D PHF model generated using 3DPT was able to provide the visual display and omni-directional observation of the direction and severity of the fracture dislocation, which facilitated preoperative diagnosis, operation planning and design, data measurement, preselection of internal fixator and surgical outcome simulation. According to the follow-up ranging from 12∼28 months for the 66 patients, the results showed no significant difference in time to union between the two groups (P>0.05). Apart from that, less surgery duration, less blood loss during surgery, less number of fluoroscopy can be observed compared with the control group (P<0.05). CONCLUSIONS In this study, 3DPT showed great clinical feasibility of the treatment of complicated PHFs. The 3D-print PHF model had the ability to clearly display the fracture and thus was useful to determine the fracture classification and the magnitude of fracture injury. It benefited surgeons to gain a better understanding of complicated PHFs, design a most suitable operation plan prior to surgery and facilitate the doctor-patient communication. This therefore enabled the reduction of intraoperative injury and the optimization of surgical outcomes.

Abstract
The aim of this study was to evaluate the effects of miR-26a on Beclin 1 expression in retinoblastoma (RB) cell lines (Y79 and WERi-RB-1). RB cells were transfected with miR-26a mimic, antagomir-26a, or control mimic. The Beclin 1 mRNA and protein levels were detected by quantitative polymerase chain reaction and western blot, respectively. The activity of Beclin 1 3ꞌ-UTR reporter gene was detected with the luciferase assay. After transfection with miR-26a mimic, Beclin 1 mRNA and protein levels as well as the activity of the 3'-UTR reporter gene decreased. However, all were increased upon inhibition of miR-26a with antagomir-26a. Beclin 1 is the target of miR-26a in human RB cell lines Y79 and WERi-RB-1, and miR-26a inhibits the expression of Beclin 1 by reducing its mRNA and protein levels.

Abstract
Aperture alignment is crucial for the diagnosis of neutron imaging because it has significant impact on the coding imaging and the understanding of the neutron source. In our previous studies on the neutron imaging system with coded aperture for large field of view, "residual watermark," certain extra information that overlies reconstructed image and has nothing to do with the source is discovered if the peak normalization is employed in genetic algorithms (GA) to reconstruct the source image. Some studies on basic properties of residual watermark indicate that the residual watermark can characterize coded aperture and can thus be used to determine the location of coded aperture relative to the system axis. In this paper, we have further analyzed the essential conditions for the existence of residual watermark and the requirements of the reconstruction algorithm for the emergence of residual watermark. A gamma coded imaging experiment has been performed to verify the existence of residual watermark. Based on the residual watermark, a correction method for the aperture misalignment has been studied. A multiple linear regression model of the position of coded aperture axis, the position of residual watermark center, and the gray barycenter of neutron source with twenty training samples has been set up. Using the regression model and verification samples, we have found the position of the coded aperture axis relative to the system axis with an accuracy of approximately 20 μm. Conclusively, a novel approach has been established to correct the coded aperture misalignment for fast neutron coded imaging.
