Abstract
Objective: To investigate the incidence of asymptomatic sinusitis in children by magnetic resonance imaging. Method: Collected the head MRI of 1-12 years old children. According to the examination site,the MRI group and the pituitary MRI group (both sinus level) were included.The nasal-sinusitis-like changes in the field were used as positive criteria. Statistical analysis was conducted on the test results. Result: In 3 900 children with MRI, the positive rate of sinusitis was 30.21%. The positive rate increased from 2 years old to 3 years old and remained at the age of 11 years.The higher positive rate was slightly decreased at 12 years old; 1 228 cases of pituitary MRI examination, the positive rate of nasal-sinusitis was 38.27%, the positive rate increased significantly from the age of 2, reached the peak at 6 years old, and then fell back, still kept high positive rate, the lowest to 12 years old. The positive rate of total sinusitis was 32.14%. No obvious difference was found between two groups. Conclusion: Children's skull and pituitary MRI imaging suggests that the positive rate of nasal-innocuous sinusitis is related to age, peaking at 3 to 8 years old, and then gradually decreasing.

Abstract
Chronic liver disease has caused increasing numbers of deaths worldwide. Fatty liver hemorrhagic syndrome, one of the chronic liver diseases in laying hens, has great similarity to non-alcoholic fatty liver disease (NAFLD) in humans. It is characterized by the pathological accumulation of liver fat. Non-invasive techniques are needed for early identification of fibrosis. As primary de novo lipogenesis in the liver of chicken is similar to that of humans, mature chicken is an ideal animal model for the understanding of NAFLD. This study was aimed to evaluate the relationships between gut microbiota and natural chronic liver disease (i.e., non-alcoholic steatohepatitis [NASH] and fibrosis stages) in a well-characterized laying hen population. One hundred 20-wk-old Hy-Line Brown laying hens were used and fed with basal diets until 52 wk of age. At the end of the experiment, birds were killed for sampling blood, liver, and cecal contents, and then classified by liver histology measurement into different groups. We investigated microbial community structure of cecum using 16S rRNA gene sequencing. Subjects in stage 0 fibrosis without NASH were classified as low NAFLD (Group A), subjects in stage 1-2 fibrosis with mild to moderate NASH were defined as low NASH (Group B), and subjects in stage 3 fibrosis were defined as severe NASH (Group C). The abundance of Firmicutes was reduced in Groups B and C (P < 0.001), whereas opposite results were observed for the abundance of Bacteroidetes. Additionally, the families Bacteroidaceae, Ruminococcaceae Lachnospiraceae, and lactobacillae were significantly different between groups of differing fibrosis stages (P < 0.001), driven entirely by alterations of Bacteroides and lactobacillus and lachnospiraceae genera (P < 0.001), were observed. Results indicated that cecal dysbiosis was linked with the severity of fibrosis and NASH; importantly, increased levels of serum AST, alkaline phosphatase, and uric acid were accompanied with liver fibrosis and NASH severity. Collectively, these data highlight the role of gut-liver axis and associations between the gut microbiota and fibrosis and NASH severity.

Abstract
Objective: To determine whether asthma has a different metabolic glycerophospholipid profile in serum between women and men with asthma. Methods: Fifty-one outpatients with asthma (17 men, 34 women) were enrolled from Peking University Third Hospital from Jan 2015 to Dec 2015. Clinical data such as gender, age, body mass index, pulmonary function were recorded. Glycerophospholipid profile were measured in serum using liquid chromatography-mass spectrometry (LC-MS)-based metabolomics analysis. Projections to latent structures-discriminate analysis (PLS-DA) was used to compare the differences of glycerophospholipid level between men and women. Receiver Operating Characteristic (ROC) Curve was established from men and women. Results: Significantly different glycerophospholipid level were confirmed quantitatively between women and men. Levels of phosphatidylethanolamine (PE), phosphatidylcholine acetal phospholipid (PCP), lysophosphatidyl ethanolamine (LPE), alkyl phosphatidylethanolamine [PE(O)] were significantly higher in women relative to men [PE36: 2, PCP32: 1, LPE18: 0, and PE(O40: 7) was 0.050 (0.037, 0.079) vs 0.043 (0.000, 0.071), 0.057 (0.035, 0.727) vs 0.034 (0.000, 0.057), 0.233 (0.129, 0.390) vs 0.126 (0.075, 0.212), 0.007(0.000, 0.041) vs 0.000 (0.000, 0.000), respectively, all P<0.05). Levels of lysophosphatidylcholine (LPC), lysophosphatidylserine (LPS), and lysophosphatidylphosphatidylcholine [LPC(O)] were significantly lower in women compared to men [Levels of LPS22: 6, LPS20: 4, and LPS18: 1 were 0.000(0.000, 0.003) vs 0.009(0.000, 0.012), 0.015(0.010, 0.026) vs 0.047(0.022, 0.081), 0.008(0.003, 0.179) vs 0.020(0.008, 0.040), respectively, all P<0.05]. Area Under ROC Curve (AUC) of LPS (LPS20: 4) was 0.814. Conclusions: Glycerophospholipid levels in serum are significantly different between women and men asthmatic patients. LPS may contribute to gender based differences in asthmatics.

Abstract
The role of Grb2-associated binder 1 (Gab1) in bFGF-activated PI3K-AKT pathway of endothelial cells remains largely unknown. To elucidate this role, a set of studies with siRNA knockdown of Gab1 was performed. Knockdown of Gab1 using siRNA was performed in fused endothelial cell line EA.hy926 and the low level of Gab1 was confirmed with quantitative R-T PCR and Western blotting. Effects of Gab1 down-regulation were examined on several aspects: bFGF-induced AKT phosphorylation, proliferation, migration and vessel tubing formation of EA.hy926 cells. The bFGF-induced AKT phosphorylation of wild-type EA.hy926 cells was both dose-dependent and time dependent with a peak at 10 ng/ml and about 30 min after bFGF treatment. The AKT activation was significantly reduced in Gab1 siRNA-treated EA.hy926 cells. The blocking of Gab1-AKT path resulted in a set of biological alterations of EA.hy926 cells: (i) reduced proliferation; (ii) impaired migration; (iii) decreased vessel tubing formation in both 2D and 3D culture. All data support that Gab1 is associated with angiogenesis function of EA.hy926 endothelium cells via PI3K-Akt signaling pathway.

Abstract
The ban on the use of antibiotic feed additives as growth promoters compelled the researchers for exploring the future utility of other alternatives. This experiment was designed to evaluate the effect of acidified drinking water on growth performance, gastrointestinal pH, digestive enzymes, intestinal histomorphology, and cecum microbial counting of the broiler chicken. A total of 540 one-day-old male broilers (Arbor Acre) were randomly assigned to 5 treatments, with 6 replicates of 18 chicks per replicate. Broilers received diets and water as follows: NC (negative control, basal diet, normal water), PC (positive control, basal diet + 8 ppm colistin sulfate + 8 ppm enduracidin, normal water), A1 (basal diet, continuous supply of acidified water during whole experiment period), A2 (basal diet, intermittent acidification of water during 0 to 14 d, 22 to 28 d, and 36 to 42 d), and A3 [basal diet, intermittent acidification of water (24 h/d from 0 to 14 d and from 10:00 am to 4:00 pm on d 15 to 42)]. During the entire period, the acidified groups (A1, A2, and A3) and PC group showed improve on weight gain, average daily gain and feed conversion ratio compared to NC group (P < 0.05). The pH in crop, proventriculus and ileum at 43 d declined by 0.04, 1.03, 1.23; 0.55, 0.69, 0.70; and 0.63, 0.74, 1.21 in A1, A2, and A3 group, respectively. There was a significant decline of lipase activity in the PC and acidified groups compared to NC group. The A2 group had higher villus height in jejunum than NC group. The PC and acidified groups reduced (P < 0.05) the total aerobic bacteria count of cecum when contrasted to NC group. Therefore, we conclude that acidified drinking water can improve growth performance, compensate for gastric acidity, and control pathogenic bacteria in broilers and may be considered as a potential alternative to improve production parameters. Discontinuous supply of acidified water had the same or even better influence on broilers compared to continuous supply.

Abstract
This study compared the effects of sodium selenite and selenium yeast and their combination on laying performance, egg quality, antioxidant capacity, and selenium (Se) contents in tissues and eggs. Two-hundred-eighty-eight Jing Hong layers that were similar in laying rate (87.5 ± 0.38%) and body weight (1.70 ± 0.02 kg) were randomly distributed into 4 treatments for 11 wk (from 203 d old to 279 d old) with 9 replicates of 8 hens per replicate. The diets (corn-soybean meal diet) were supplemented with 0 [blank control (BC)], 0.3 mg/kg Se from sodium selenite (SS), 0.15 mg/kg Se from sodium selenite and 0.15 mg/kg Se from Se yeast (SS+SY), or 0.3 mg/kg Se from Se yeast (SY). Results showed that the laying rate of the SS+SY group increased significantly (P < 0.05) compared to the BC and SY groups. There were no differences (P > 0.05) in egg quality between the Se-supplemented diets and the BC diet. The serum glutathione peroxidase (GSH-Px) activity was increased (P < 0.01) in hens fed Se-supplemented diets compared to the BC diet. The liver superoxide dismutase (SOD) activity of the SY group was increased significantly (P < 0.05) compared to the BC group. Significant increase (P < 0.01) due to SY supplementation was noted in the serum vitamin E content compared to BC and SS. Layers fed Se-supplemented diets had higher (P < 0.01) contents of Se in the serum, liver, and kidney compared to the BC diet. Compared to BC, Se content in eggs was significantly increased (P < 0.05) by feeding supplementary Se. In conclusion, the effects of SS and Se yeast were approximately equal in promoting antioxidant capacity of laying hens, while Se yeast is easier to deposit into eggs and tissues. The diet with added equal amounts of the 2 sources of Se was more cost effective and affordable than a comparable amount of Se yeast to obtain the promising production performance and nearly similar Se deposition.

Abstract
Objective: Investigate the effects of inducible ppp2r1a knockout on main physiological function in adult mice and study the mechanism. Methods: Ppp2r1a(flox/flox) mice and CAGG-CreER mice were hybridized to obtain 20 CAGG-CreER ppp2r1a(flox/flox) and 20 mice in homozygous group. Two groups of mice were divided into 4 groups respectively, finally we got 8 groups with 5 mice in each group. Tamoxifen was injected intraperitoneally to acquire inducible ppp2r1a knockout mice. The knockout efficiency of PP2A Aα in vital organs was measured by Western blot. At 0, 2, 4 and 6 days after injection, we measured body weight, histopathological change, peripheral blood cell counts and blood biochemical. Real-time PCR was performed to measure expression of liver glucolipid metabolism genes. Results: After tamoxifen injection for 6 days, the knockout efficiency of PP2A Aα in vital organs was 35%, 12%, 15%, 60%, 69% and 72%, respectively in heart, liver, spleen, lung, kidney and brain. After tamoxifen injection for 6 days, the weight of homozygous mice was lower than that of wild type mice, with values of (17.42±1.76) g and (21.69±1.82) g, respectively (P<0.05). Moreover, the activity level, abdominal and renal fat were significantly decreased in homozygous mice. Homozygous mice survived no more than 7 days. Compared with wild type mice, the organ coefficient of spleen of homozygous mice was decreased at the 6th day, with values of (0.59±0.10)% and (0.36±0.05)% respectively (P<0.05). Obvious spleen atrophy and marked decrease of nucleated cells were showed by performing HE staining. Tunel staining revealed increased apoptosis ratio of splenic lymphocytes in homozygous mice. The levels of alanine aminotransferase (ALT) and aspartate transaminase (AST) of homozygous mice were higher than wild type mice (P<0.05). The values of ALT and AST in homozygous mice were (153.68±62.80) U/L and (193.2±44.28) U/L. The corresponding values in wild type mice were (41.02±12.91) U/L and (69.40±9.55) U/L. The above results indicated that ppp2r1a knockout caused liver damage. Blood sugar level of homozygous mice was lower than in wild type mice (P<0.05), with values of (4.20±1.99) mmol/L and (8.88±0.65) mmol/L respectively. Plasma total cholesterol (TC), high density lipoprotein (HDL) and β-hydroxybutyric acid (β-HB) level of homozygous mice were higher than those of wild type mice (P<0.05). The values of TC, HDL and β-HB in homozygous mice were (3.12±0.39), (1.53±0.38) and (2.49±0.89) mmol/L. The corresponding values in wild type mice were (1.69±0.92), (0.78±0.50) and (0.45±0.30) mmol/L respectively. The above results indicated that ppp2r1a loss interfered glucose and cholesterol metabolism. In addition, we also found that the white blood cell count (WBC) and lymphocyte count (LYM) of homozygous mice were lower than in wild type mice (P<0.05). The values of WBC and LYM in homozygous mice were (1.88±0.89)×10(9)/L and (0.92±0.37)×10(9)/L respectively. The corresponding values in wild type mice were (3.91±0.80)×10(9)/L and (2.74±0.52)×10(9)/L respectively. The mRNA levels of glucose-6-phosphatase (G6P) and phosphoenolpyruvate carboxykinase (PEPCK) of homozygous were lower than wild type mice (P<0.05). The fold change of G6P and PEPCK in homozygous mice was 0.46±0.11 and 0.72±0.07 respectively. The corresponding fold change in wild type mice was 1.02±0.07 and 1.02±0.06 respectively. Conclusion: Whole body ppp2r1a is essential for the survival of adult mice, due to the important role in maintaining the metabolism of glucose and cholesterol of liver.

Abstract
Over supplementation of copper (Cu) in animal diets may cause serious pollution in soil, water and harvested crops. To minimize the potential pollution, the effects of corn-soybean basal diet with or without supplementation of 8 mg Cu/kg on laying performance, plasma biochemical metabolic indices, and antioxidant status in laying hens were evaluated under normal and cyclic high temperatures. A total of 240 Hy-Line Brown laying hens were randomly allotted to 4 treatments with 6 replicates of 10 hens per replicate according to factorial design involved in 2 temperatures [normal temperature (NT) vs. cyclic high temperature (CHT)] and 2 dietary Cu addition amount [Cu0 (0 mg/kg) vs. Cu8 (8 mg/kg in the form of CuSO4·5H2O)]. The experimental period included 1-week adaptation, 2-week heat stress and 2-week convalescence. The temperatures of NT groups in the same period or any groups during other periods were kept at 26 ± 2°C except that of CHT groups were 26 ± 2°C∼33 ± 2°C cyclically during heat stress period. CHT groups increased (P < 0.05) the rectal temperature and plasma glucose content under heat stress, but decreased (P < 0.01) the egg yield at the second week of heat stress and the first week of convalescence, and the plasma triglyceride, uric acid, and triiodothyronine levels under heat stress. Cu8 groups increased (P < 0.05) egg weight at the first week of convalescence, and plasma thyroxin level during the whole convalescence. Interactions between temperature and Cu content existed (P < 0.05) in the laying rate at the first week of convalescence, and the plasma lactic dehydrogenase level under heat stress. Conclusively, the CHT impaired laying performance. The Cu content (10.3 mg/kg) in corn-soybean basal diet might be sufficient for meeting the maintenance and production requirements of late-phase laying hens, and no Cu supplementation had no adverse effects on egg production and antioxidant indices under cyclic high (26 ± 2°C∼33 ± 2°C) or normal (26 ± 2°C) temperatures.

Abstract
Objective: To evaluate the predicting value of the 2014 European Society of Cardiology (ESC) guidelines risk prediction model for sudden cardiac death (HCM Risk-SCD) in Chinese patients with hypertrophic cardiomyopathy (HCM), and to explore the predictors of adverse cardiovascular events in Chinese HCM patients. Methods: The study population consisted of a consecutive 207 HCM patients admitted in our center from October 2014 to October 2016. All patients were followed up to March 2017. The 5-year SCD probability of each patient was estimated using HCM Risk-SCD model based on electrocardiogram, echocardiography and cardiac magnetic resonance (CMR) examination results. The primary, second, and composite endpoints were recorded. The primary endpoint included SCD and appropriate ICD therapy, identical to the HCM Risk-SCD endpoint. The second endpoint included acute myocardial infarction, hospitalization for heart failure, thrombus embolism and end-stage HCM. The composite endpoint was either the primary or the second endpoint. Patients were divided into the 3 categories according to 5-year SCD probability assessed by HCM Risk-SCD model: low risk group<4%,intermediate risk group ≥4% to<6%, and high risk group≥6%. Results: (1) Prevalence of endpoints: All 207 HCM patients completed the follow-up (350 (230, 547) days). During follow-up, 8 (3.86%) patients reached the primary endpoints (3 cases of SCD, 3 cases of survival after defibrillation, and 2 cases of appropriate ICD discharge); 21 (10.14%) patients reached the second endpoints (1 case of acute myocardial infarction, 16 cases of heart failure hospitalization, 2 cases of thromboembolism, and 2 cases of end-stage HCM). (2) Predicting value of HCM Risk-SCD model: Patients with primary endpoints had higher prevalence of syncope and intermediate-high risk of 5-year SCD, as compared to those without primary endpoints (both P<0.05). (3) Predicting value of HCM Risk-SCD model: The low risk group included 122 patients (59%), the intermediate risk group 42 (20%), and the high risk group 43 (21%). There was a clear trend towards to higher heart rate, higher values of PTF(V1) and plane QRS-T angle, higher left ventricular mass index (LVMI), elevated maximal left ventricular outflow tract pressure gradient (LVOT-PGmax), enlarged left atrial dimension(LAD) and volume index (LAVI), reduced systolic mitral annular velocity (s'), and higher late gadolinium enhancement (LGE) volume and mass in patients with high risk of 5-year of SCD, as compared to those with low-intermediate risk (all P<0.05). Moreover, 5-year SCD probability was positively correlated with heart rate, plane QRS-T angle, LVMI, LAVI, LGE%, and negatively correlated with s'(r=0.161, P=0.019; r=0.669, P=0.001; r=0.206, P=0.004; r=0.284, P=0.000; r=0.351, P=0.000; r= -0.245, P=0.001; respectively). (4) LAD, LAVI, e' and s' were independent predictors for poor outcomes. HCM patients with LAD≥39 mm, LAVI≥49.6 ml/m(2), e'≤6.5 cm/s and s'≤6.6 cm/s were more likely to have adverse cardiovascular events (AUC 0.702, 95%CI 0.604-0.799, P=0.001; AUC 0.700, 95%CI 0.567-0.833, P=0.001; AUC 0.716, 95%CI 0.616-0.817, P=0.000; AUC 0.764, 95%CI 0.676-0.853, P=0.000,respectively). Conclusions: The HCM Risk-SCD model is of value in predicting SCD for Chinese HCM patients. The plane QRS-T angle and LGE% are the best predictors of 5-year SCD risk in Chinese HCM patients. Moreover, conventional echocardiographic parameters, including LAD, LAVI, e' and s', are useful to predict adverse cardiovascular events among Chinese HCM patients.

Abstract
Objective: To investigate the relationship between the recurrence of benign paroxysmal positional vertigo(BPPV) and the levels of bone mineral density(BMD) and estrogen in postmenopausal women. Methods: A total of 38 postmenopausal women with recurrent BPPV were recruited as study group, in the First Affiliated Hospital of Soochow University from December 2013 to June 2017. Meanwhile, 49 normal menopausal women were included as control. All patients were natural menopausal for over one year.The patients were diagnosed as BPPV based on results of Dix-Hallpike test and Roll-test, with at least two episodes of recurrent onset. In the subjects, BMD was measured by dual X-ray absorptiometry of lumbar vertebrae. Estrogen levels were obtained by testing serum estradiol (E2) levels in early morning fasting venous blood. In the present study, we compared the level of E2 and the value of BMD in two groups by SPSS 21.0. In the study group, patients with decreased BMD were divided into two groups: treatment and untreated group. The recurrence rate of BPPV was compared between the two groups within 12 months. Results: ①The averagel levels of E2 and BMD in the study group were (16.21±11.00)ng/L and -1.68±0.98) respectively, which were significantly lower than those in the control group (t value was 7.03 and 8.05 respectively, both P<0.05). The averagel levels of E2 and BMD incontrol group were(28.52±6.34)ng/L and -0.18±0.77 respectively. ②The number of patients with decreased BMD in the study group (30 cases) was more than that in control group (6 cases), and the difference was statistically significant (P<0.05). ③ The recurrence rate of BPPV in treatment group [17.6%(3/17)] was significantly lower than that of untreated group [61.5%(8/13)], and the difference was statistically significant (P<0.05). Conclusion: Recurrent BPPV in postmenopausal women usually accompany with low levels of estrogen and BMD. Active treatment is helpful for their recurrence of BPPV.

Abstract
In recent years, hepatocellular carcinoma (HCC) has become one of the serious health-threatening malignancies worldwide, and its incidence and mortality rates continue to rise. Hepatitis B (HBV) is moderately endemic in China, with enormous numbers of HBV-related HCC cases. Although serum alpha-fetoprotein (AFP) and ultrasound are the major diagnostic methods for HCC, they have limited application for screening out early or small HCC. The current management of HCC is based on tumor size and location, not on suppressing tumorigenesis, and therefore patients are often faced with low 5-year survival and high relapse rates. Recent studies have shown that long-chain non-coding RNAs (lncRNAs) are closely associated with HCC tumorigenesis, which may have considerable utility as new diagnostic marker and treatment target for HCC. Here, we review the application of lncRNAs in the diagnosis, metastasis, treatment, recurrence, and prognosis of HCC.

Abstract
Objective:To explore the method of screening effective antibiotics in active stage of otitis media, in order to lay ground for rational clinical application of antibiotics in this scenario.Method:The clinical data of 198 patients diagnosed as otitis media were analyzed. Based on the results of bacterial culture and drug sensitivity test of middle ear secretion, the clinical availability and the ototoxicity of corresponding drugs, first and second line drugs were screened to control infection. The therapeutic effect of drugs was summarized.Result:In 21 out of 198 cases, there was no growth of common bacteria, while in the remaining 177 cases, there were 36 cases(20.34%) of coagulase negative staphylococcus, which was sensitive to linezolid, vancomycin, cefuroxime, levofloxacin, SMZ-TMP, and rifampin; 30 cases(16.95%) of pseudomonas aeruginosa, which was sensitive to meropenem, imipenem, ceftazidime, amikacin, and piperacillin; and 26 cases(14.69%) of staphylococcus aureus, which was sensitive to linezolid, vancomycin, oxacilin, gentamycin, levofloxacin, ciprofloxacin, moxifloxacin. Drugs that were administrated based on experience including: local use of levofloxacin eardrops, cefuroxime and moxifloxacin as first line oral antibiotics, and ceftazidime as second line oral antibiotics. There were 3 cases of post-operational infection, which recovered after systemic and local use of sensitive drugs and dressing.Conclusion:In otitis media, sensitive antibiotics chosen from results of bacterial culture and drug sensitivity test, are useful in reducing the complication of infection after surgery.

Abstract
This prospective, randomised study was conducted to assess the effect of flexible laryngeal mask airway (FLMA) size on oropharyngeal leak pressure (OLP) in children at the recommended intracuff pressure. A total of 120 children undergoing elective ophthalmic surgery were randomly assigned to the size 2 FLMA group or size 2.5 FLMA group. The primary measurement was OLP at an intracuff pressure of 40 cmH2O. Secondary outcomes included the incidence of OLP <10 cmH2O, insufficient ventilation, gastric insufflation, insertion time, successful first-attempt insertion rate, fibreoptic view grade and pharyngolaryngeal adverse events. The median OLP was comparable for the size 2 and size 2.5 FLMA (18 cmH2O versus 18 cmH2O, P=0.38). However, the size 2 FLMA group had a higher incidence of OLP <10 cmH2O and insufficient ventilation (13.3% versus 0, P=0.006). In subgroup analyses based on weight, the size 2.5 FLMA had a lower occurrence of OLP <10 cmH2O and insufficient ventilation (27% versus 0, P=0.0046) in children 16-20 kg. We conclude that at a 40 cmH2O intracuff pressure, the OLP with the size 2 and size 2.5 FLMA was similar in children weighing 10-15.9 kg. However, in children weighing 16-20 kg, size 2 devices had a higher incidence of low OLP and insufficient ventilation, so a 2.5 FLMA may be preferable in this subgroup.

Abstract
This study aimed to explore the association between ring finger protein 41 (RNF41) c.-206 T > A variant and susceptibility to congenital heart disease (CHD) in the Chinese Mongolian population. The association between RNF41 gene c.-206 T > A polymorphism and CHD was examined in two independent case-control studies consisting of 219 CHD patients and 208 healthy controls. Genotype was determined by direct sequencing of PCR products. We found that the genotype frequencies of RNF41 c.-206 T > A differ significantly between the two groups (P < 0.05). The TT and TA genotypes in the CHD group were 80.67 and 19.33%, respectively. On the other hand, the frequencies of TT and TA in the control group were 94.44 and 5.56%, respectively. Furthermore, the allelic frequencies of CHD patients (T, 90.34%; A, 9.66%) were significantly different as compared with those of non-CHD controls (T, 97.22%; A, 2.78%; χ2 = 4.031, P = 0.041). Our study demonstrates that the RNF41 c.-206 T > A polymorphism may be a risk factor for congenital heart disease in the Chinese Mongolian population.

Abstract
Previous study has indicated that exposure to anesthesia in early development leads to neuro-apoptosis and is followed by long-term cognitive dysfunction. Given that larger numbers of pregnant women currently receive anesthesia during the first trimester, we wanted to mimic this process in vitro using mouse embryonic stem cells (mESCs) and to explore how different anesthetics affect the self-renewal of mESCs. In the present study, mESCs were exposed to dexmedetomidine, fentanyl, or remifentanil at clinical concentrations for 48 h. The mESCs were then analyzed for cell proliferation and apoptosis. Furthermore, we used flow cytometry to analyze the cell cycle and quantitative real-time polymerase chain reaction to detect the gene expression during the cell cycle as well as the relevant stemness markers. We found that prolonged anesthesia with dexmedetomidine or fentanyl significantly inhibited mESC proliferation, with fewer cell numbers as well as decreased expression of cyclin B and cyclin E mRNA compared to that in the control group; meanwhile, p21 and RB2 gene expression was increased. Additionally, increases or decreases in the proportion of cells in the G1 and S phases, respectively, were observed in the dexmedetomidine- and fentanyl-treated groups. These anesthetics also repressed the gene expression of mESC stemness makers such as Oct4 and Sox2. However, remifentanil seemed to have no significant influence on the self-renewal of mESCs. These results demonstrated that prolonged anesthesia with dexmedetomidine or fentanyl, but not remifentanil, inhibited mESC proliferation by blocking the G1 to S transition, and repressed the maintenance of mESC stemness.

Abstract
An experiment was conducted to investigate the effects of environmental temperature and dietary Mn on egg production performance, egg quality, and some plasma biochemical traits of broiler breeders. A completely randomized factorial design involved 2 environmental temperatures (a normal temperature, 21 ± 1°C, and a high temperature, 32 ± 1°C) × 3 dietary Mn treatments (a Mn-unsupplemented corn–soybean meal basal diet or the basal diet supplemented with 120 mg of Mn/kg of diet as either MnSO4·H2O or manganese proteinate). There were 6 treatments with 6 replicates (4 birds per replicate). High temperature decreased egg weight (P < 0.0001), laying rate (P < 0.0001), egg yield (P < 0.0001), feed intake (P < 0.0001), egg:feed ratio (P < 0.0001), eggshell strength (P < 0.05) and thickness (P < 0.0001), plasma triiodothyronine level (P < 0.05), and alkaline phosphatase activity (P < 0.04) whereas it increased rectal temperature (P < 0.0001); plasma malondialdehyde level (P < 0.02); and activities (P < 0.002) of lactic dehydrogenase, aspartate aminotransferase, and creatine kinase. Broiler breeders fed the diets supplemented with Mn regardless of source had greater (P < 0.05) eggshell strength and lower (P ≤ 0.05) plasma triiodothyronine level and protein carbonyl content than those fed the control diet. The broiler breeders fed the diet supplemented with the organic Mn had greater (P < 0.01) eggshell thickness than those fed the control diet. There were interactions (P < 0.05) between environmental temperature and dietary Mn in laying rate, egg yield, feed intake, and egg:feed ratio. Under normal temperature, dietary Mn did not affect the above 4 parameters; however, under high temperature, broiler breeders fed the diet supplemented with the organic Mn showed greater (P < 0.03) improvements in these 4 parameters than those fed the control diet. The results from this study indicated that high temperature significantly impaired egg production performance and eggshell quality and induced lipid peroxidation and tissue damage whereas dietary supplementation of either organic or inorganic Mn improved eggshell strength and thermotolerance and reduced protein oxidation and that the organic Mn could alleviate the negative effect of high temperature on egg production performance of broiler breeders at the period of 32 to 45 wk of age.
