Abstract
Objective: To assess the association and intensity of baseline dyslipidemia with the incidence of carotid plaque in a researchers group in China. Methods: A total of 716 researchers were enrolled in this prospective cohort study. Dyslipidemia was assessed in 2010. Follow-up study on carotid plaque was conducted in 2017. Results: Over 8 years' follow-up, 289 carotid plaque patients were identified among 716 individuals who did not have carotid plaque at baseline survey, with cumulative incidence of 40.36%. After adjustment of age, gender, BMI, waist circumference, FPG, SBP, DBP, ALT and uric acid, compared with non-dyslipidemia group, HR of carotid plaque for such populations with ≥3 types of dyslipidemia was 1.681 (95%CI: 1.090--2.593). Conclusions: Dyslipidemia might be associated with higher risk of carotid plaque, and population with ≥3 types of dyslipidemia had higher risk for carotid plaque. Prevention of dyslipidemia or reduction of types of dyslipidemia might be one of the effective precautions for prevention of carotid plaque.

Abstract
Objective: To explore the biomarkers that applied to pulmonary acute respiratory distress syndrome (ARDS) and extrapulmonary ARDS respectively. Methods: A total of 49 eligible patients with ARDS were selected from Department of Respiratory intensive care unite (ICU) , Department of General ICU and Department of Emergency ICU, the Second Affiliated Hospital of Nanchang University, during April 2015 and February 2016, and divided into pulmonary ARDS group (n=26) and extrapulmonary ARDS group (n=23) according to primary causes. Totally 19 cases from healthy examination personnel were served as control. Acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ) score and lung injury score of all hospitalized patients were completed within 24 hours after the diagnosis of ARDS and the serum levels of angiogenin2 (Ang-2) , surfactant protein D (SP-D), soluble receptor for advanced glycation end products (sRAGE), Krebs von den Lungen-6 (KL-6) were measured. Then the 28-day outcomes were observed. The serum levels of the biomarkers were compared between each group and correlation analysis was conducted between different indexes. Finally, The relationship between the four biomarkers and the outcome of each group was analyzed. Results: The serum level of Ang-2 in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[1 462 (569, 3 638) and 4 568 (2 236, 8 457) vs 460 (389, 578) ng/L, all P<0.05], and the serum level of Ang-2 was significantly higher in extrapulmonary ARDS group than that in pulmonary ARDS group (P<0.05). The serum level of SP-D in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[5.9 (2.5, 22.7) mg/L and 3.7 (1.7, 6.5) vs 1.9 (0.6, 4.4) mg/L, all P<0.05], and the serum level of SP-D was significantly higher in pulmonary ARDS group than that in extrapulmonary ARDS group (P<0.05). The serum level of sRAGE in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[238 (101, 583) and 229 (114, 443) vs 117 (88, 176) ng/L, all P<0.05]. The serum level of KL-6 in pulmonary ARDS group was significantly higher than that in control group[10 435 (3 401, 17 607) vs 4 780 (3 962, 5 320) U/L, P<0.05]. Increased serum levels of SP-D (OR=1.089, 95% CI: 1.001-1.085) and KL-6 (OR=1.206, 95% CI: 1.016-1.432) at the early stage were the independent prognostic factors for the 28-day mortality for pulmonary ARDS. Advanced age (OR=2.622, 95% CI: 1.046-6.574) was the independent prognostic factor for the 28-day mortality for extrapulmonary ARDS. Conclusion: SP-D and KL-6 may be the serum biomarkers of pulmonary ARDS and Ang-2 may be the serum biomarker of extrapulmonary ARDS.

Abstract
Objective: To explore the incidence and severity of hepatic adverse events (AEs) and identify factors associated with hepatic AEs in patients with chronic myeloid leukemia (CML) in chronic phase (CP) treated with tyrosine kinase inhibitors (TKIs). Methods: Liver biochemistry parameters [including ALT(alanine aminotransferase), AST(aspartate aminotransferase), ALP(alkaline phosphatase), and TBil(total bilirubin)] during the first 6 months on imatinib (Gleevec(®)), dasatinib (Sprycel(®)) or nilotinib (Tasigna(®)) in CML-CP patients were collected and analyzed retrospectively. Results: A total of 436 patients were enrolled in this study, including 271 with imatinib, 58 with dasatinib, and 107 with nilotinib. The incidences of any abnormality of liver injury were 21.8%(59/271), 15.5%(9/58) and 32.7%(35/107) in the imatinib, dasatinib and nilotinib groups, respectively. Most of the hepatic AEs were CTCAE grade 1 or 2 and mild or moderate liver injury except 1.9% of TBil CTCAE grade 3 in the nilotinib group. Multivariate analyses showed nilotinib [OR=2.9(1.3-6.6), P=0.012; OR=4.4(1.2-15.6), P=0.023] and male gender [OR=2.3(1.4-3.9), P=0.002; OR=3.0(1.2-7.6), P=0.018] were significantly associated with moderate liver impairment. Conclusions: TKIs including imatinib, dasatinib and nilotinib were well tolerated with mild to moderate hepatic AEs in CML-CP patients. Nilotinib and male sex were associated with occurrence of liver biochemistry abnormalities and moderate hepatic injury.

Abstract
A new carbonized pomelo peel biosorbent (MCPP) modified with nanoscale zero-valent iron (NZVI) and cetyl-trimethyl ammonium bromide was prepared and employed for the adsorption of molybdate (Mo(VI)) from aqueous solution. We investigated the effects of various conditions on Mo(VI) adsorption and evaluated the results based on adsorption kinetics models and isotherm equations. The kinetic data fitted to the pseudo-second-order model. The Langmuir model best described the adsorption of Mo(VI) on MCPP. The values of changes in Gibbs free energy, standard enthalpy, and standard entropy revealed that the adsorption process was feasible, spontaneous and endothermal. X-ray diffraction, Fourier transform infrared and X-ray photoelectron spectroscopy measurements suggested that Mo(VI) adsorption occurred via both the reduction and surface adsorption. Thus, biochar, prepared from fruit residue, can be applied to remove Mo(VI) from aqueous solutions. More importantly, our results provide a sustainable approach for Mo(VI) removal from wastewater by means of functional modification.

Abstract
Objective: To evaluate the activities of daily living (ADL) and related factors in community elderly people in urban and rural areas of Beijing. Methods: A population-based cross-sectional study was conducted in Haidian and Miyun districts of Beijing using two-stage random cluster sampling method between 2011 and 2014. Results: A total of 4 499 community elderly people (1 815 males, 2 684 females) aged 60-95 years were included in the study. The mean age was (70.3±6.7) years. Compared with the participants from urban area, the participants from rural area had lower education level (85.2% had education level primary school), but higher level of smoking (22.8%) and drinking (43.1%). The ADL disability rate was higher in rural area than in urban area (12.4% vs. 11.8%, P=0.039). And it increased significantly with age (P<0.05). Multivariate logistic regression showed besides urban-rural difference (P=0.031), age (P=0.013), education level (P=0.015), physical activity (P=0.001) and stroke (P<0.001) were related factors influencing ADL disability. Conclusions: The ADL disability was relatively low in the community elderly people in Beijing, and there was significant difference between rural area and urban area. Older age, lower education level and physical inactivity and stroke were related factors.

Abstract
Objective: To investigate the effect of humidex combined with mean temperature and relative humidity on the incidence of bacillary dysentery in Hefei. Methods: Daily counts of bacillary dysentery cases and weather data in Hefei were collected from January 1, 2006 to December 31, 2013. Then, the humidex was calculated from temperature and relative humidity. A Poisson generalized linear regression combined with distributed lag non-linear model was applied to analyze the relationship between humidex and the incidence of bacillary dysentery, after adjusting for long-term and seasonal trends, day of week and other weather confounders. Stratified analyses by gender, age and address were also conducted. Results: The risk of bacillary dysentery increased with the rise of humidex. The adverse effect of high humidex (90 percentile of humidex) appeared in 2-days lag and it was the largest at 4-days lag (RR=1.063, 95%CI: 1.037-1.090). Subgroup analyses indicated that all groups were affected by high humidex at lag 2-5 days. Conclusion: High humidex could significantly increase the risk of bacillary dysentery, and the lagged effects were observed.

Abstract
Objective: To investigate the effect of Berberine on renal tubulointerstitial injury and its potential mechanism in rats with type 2 diabetes mellitus (T2DM). Methods: Thirty Sprague-Dawley rats were randomly divided into 3 groups: normal control rats (NC group), diabetic rats without drug treatment (DM group), diabetic rats treated with Berberine (BBR group) for 8 weeks. At the end of the study, blood and urine samples were collected for biochemical examination, and tubulointerstitial fibrosis was quantified by Hematoxylin and Eosin (HE) and Masson staining. The expressions of E-cadherin (E-cad), α-smooth muscle actin (α-SMA), nuclear factor-κB (NF-κB) and monocyte chemoattractant protein 1 (MCP-1) were detected by immunohistochemistry analysis, real-time polymerase chain reaction (RT-PCR) and Western blot analysis. Results: 24 h urinary microalbumin (mAlb)[(170.5±58.1) vs (253.7±53.0) mg]and urinary N-acetyl-glucosaminidase (NAG)[(33.5±7.2) vs (49.5±9.3)U/L]in diabetic rats were significantly decreased by BBR treatment(both P<0.05). The apparent renal tubulointerstitial injury was found in the DM group, which was ameliorated by BBR treatment. The expression of α-SMA, NF-κB and MCP-1 were significantly decreased, accompanied by increased expression of E-cad in BBR-treated DM rats (all P<0.05). Conclusion: BBR could ameliorate renal tubulointerstitial injury in diabetic rats, the mechanism of which may be associated with the amelioration of epithelial-mesenchymal transition (EMT) through suppressing the expression of the NF-κB and MCP-1.

Abstract
Amino acids and energy deficiency lead to lower milk protein content in dairy cows. However, the known mechanisms involved in this process do not adequately explain the variability of milk protein concentration in the mammary gland. We hypothesized that a deficiency in d-glucose (d-Glc) or AA would inhibit casein synthesis by regulating signaling pathways in mammary epithelial cells. Cow mammary epithelial cells (CMEC) were subjected to combinations of 1 of 3 concentrations of d-Glc (0, 2.50, or 17.5 mM) and 1 of 3 concentrations of AA (0, 1.03, or 7.20 mM). The effect of each mixture on cell cycle stage was assessed by flow cytometry. The expression levels of β-casein and κ-casein (encoded by CSN2 and CSN3) were measured by quantitative real-time PCR and Western blotting. Phosphorylation of Janus kinase 2 (Jak2), signal transducer and activator of transcription 5a (Stat5a), AMP-activated protein kinase (AMPK), mammalian target of rapamycin (mTOR), ribosomal protein S6 kinase 1 (S6K1), and eukaryotic factor 4E-binding protein 1 (4EBP1) were analyzed by Western blotting. The percentages of cells in the DNA postsynthetic (G2) and DNA synthesis (S) phases would decrease, with the level of d-Glc or AA declining individually, but no interaction was observed between the d-Glc and AA effects. The CSN2 and CSN3 mRNA and protein were downregulated when d-Glc or AA decreased individually from 17.5 to 2.50 mM or from 7.20 to 1.03 mM, but d-Glc deficiency had a greater effect according to the regression analysis. The phosphorylation ratio of Jak2 (Tyr1007/1008), Stat5a (Tyr694), mTOR (Ser2448), S6K1 (Thr389), and 4EBP1 (Thr37) was downregulated with the level of d-Glc or AA decline, whereas the phosphorylation ratio of AMPK (Thr183/172) was upregulated. And the change of d-Glc level had a more marked effect than AA in regulating the activity of these signaling protein above according to the regression analysis. Thus, d-Glc or AA deficiency likely reduced casein transcription via inhibition of the Jak2/Stat5 pathway, and reduced translation via suppression of the mTOR pathway by activation of AMPK, but d-Glc deficiency had a more marked effect. These indicated that deficiency of AA, and especially Glc, suppressed proliferation of CMEC and casein gene and protein expression, associated with inhibition of JAK2/STAT5 and AMPK/mTOR signaling pathways.

Abstract
Objective: To investigate the significance of Twist2 in glioma and whether it is involved in the malignant transformation of glioma by epithelial-mesenchymal transition (EMT). Methods: Using immunohistochemical method detected the expression level of Twist2 in 60 cases of gliomas (including WHO grades Ⅱ, Ⅲ and Ⅳ, each for 20 cases) and 20 cases of non-tumor brain tissues. Real-time fluorescence quantitative PCR and Western blot were used to detect the expression level of Twist2 mRNA and protein in 61 cases of fresh glioma tissue (WHO grade Ⅱ 16 cases, Ⅲ 21 cases, Ⅳ 24 cases) and 12 cases of adjacent tissues, and the expression levels of E-cadherin, N-cadherin and vimentin were also investigated in fresh glioma tissue. Results: Immunohistochemistry results showed that the percentages of Twist2 expression in glioma was 90%(54/60) compared with 30%(6/20) in non-tumor brain tissues(P<0.01). The percentages of Twist2 expression were 75% (15/20), 95% (19/20), and 100% (20/20) in the WHO gradesⅡ, Ⅲ and Ⅳ gliomas, respectively. WHO grades Ⅳ and Ⅲ were significantly higher than that of WHO grade Ⅱ (P<0.01). There was no significant difference between WHO grade Ⅳand WHO Ⅲ glioma (P>0.05). Real-time fluorescence quantitative PCR and Western blot showed that the expression level of Twist 2 in gliomas was significantly higher than that in para-cancerous tissues (P<0.01), and those in WHO grades Ⅳ and Ⅲ gliomas were significantly higher than that in WHO grade Ⅱ glioma (P<0.01). There was no significant difference between WHO grade Ⅳand grade Ⅲ glioma (P>0.05). Detection of key protein expression in EMT by Western blot displayed that the expression of E-cadherin was negatively associated with Twist2 in glioma (r=-0.972, P<0.01). The expression of N-cadherin and vimentin was positively associated with Twist2 in glioma(r=0.971, P<0.01; r=0.968, P<0.01). Conclusions: The expression of Twist2 in human glioma is positively correlated with the malignant grade of glioma, which may be involved in the malignant progression of glioma by EMT.

Abstract
INTRODUCTION Dietary restrictions are common among patients with eczema, and such practice may lead to diminished bone mineral density. This study investigated dietary intake and bone mineral density in Hong Kong Chinese children with eczema. METHODS This cross-sectional and observational study was conducted in a university-affiliated teaching hospital in Hong Kong. Chinese children aged below 18 years with physician-diagnosed eczema were recruited from our paediatric allergy and dermatology clinics over a 6-month period in 2012. Subjects with stable asthma and/or allergic rhinitis who were free of eczema and food allergy as well as non-allergic children were recruited from attendants at our out-patient clinics as a reference group. Intake of various foods and nutrients was recorded using a food frequency questionnaire that was analysed using Foodworks Professional software. Bone mineral density at the radius and the tibia was measured by quantitative ultrasound bone sonometry, and urinary cross-linked telopeptides were quantified by immunoassay and corrected for creatinine level. RESULTS Overall, 114 children with eczema and 60 other children as reference group were recruited. Eczema severity of the patients was classified according to the objective SCORing Atopic Dermatitis score. Males had a higher daily energy intake than females (median, 7570 vs 6736 kJ; P=0.035), but intake of any single food item or nutrient did not differ between them. Compared with the reference group, children with eczema had a higher intake of soybeans and miscellaneous dairy products and lower intake of eggs, beef, and shellfish. Children with eczema also consumed less vitamin D, calcium, and iron. The mean (standard deviation) bone mineral density Z-score of children with eczema and those in the reference group were 0.52 (0.90) and 0.55 (1.12) over the radius (P=0.889), and 0.02 (1.03) and -0.01 (1.13) over the tibia (P=0.886), respectively. Urine telopeptide levels were similar between the groups. Calcium intake was associated with bone mineral density Z-score among children with eczema. CONCLUSIONS Dietary restrictions are common among Chinese children with eczema in Hong Kong, who have a lower calcium, vitamin D, and iron intake. Nonetheless, such practice is not associated with changes to bone mineral density or bone resorptive biomarker.

Abstract
OBJECTIVE To investigate the image features, categories, and clinical significances of Pneumoconiosis Ш with large shadow. METHODS The research is based on the analysis of image features of 168 pneumoconiosis Ш patients who are directly diagnosed by qualified medical professionals in our institution. These image features are large shadows bigger than 2 cm×1 cm which can be observed by high kilovolt chest radiographs, DR chest radiography and chest CT scan. RESULTS Large shadows bigger than 2×1 cm show noticeable imaging characteristics, like distribution of superior and middle lung regions (95.2%) , irregular shapes (97.6%) , splayed or sausage like changes on both sides perpendicular with ribs (89.2%) , small shadows of pneumoconiosis (98.8%) , and convergence of large shadow to hilum or mediastinal (53.6%). CT scan is significantly better than DR radiography on detection rate of focal emphysema, focal cavities and swollen lymph node of mediastinal. CONCLUSION Combining the image features of high kilovolt chest radiographs, DR chest radiographs and CT scan are the main methods to identify the shadows, and thus direct diagnose pneumoconiosis Ш; CT scan plays an important role in differential diagnosis.

Abstract
Objective: To investigate whether there are changes in adherens junctions(AJ), including E-cadherin (E-cad) and β-catenin (β-cat), in the colonic mucosa of irritable bowel syndrome (IBS). Methods: Colorectal dilatation combined with restraint stress was used to establish IBS SD rat model. There were 8 rats in the model group and 8 rats in normal control group. From each rat, the colon tissue 5 centimeters away from ileocecum (I) and the junction of the rectum and sigmoid colon (R) were taken, in which E-cad and β-cat mRNA, protein level and structural changes were detected using real-time quantitative-PCR, Western blot, and immunofluorescence. According to the Rome Ⅲ criteria, IBS with diarrhea (IBS-D) patients receiving colonoscopy (n=17) and healthy volunteers (n=17) were enrolled in Center of Endoscopy of the First Affiliated Hospital of Zhejiang Chinese Medicine University. The colon tissues of I and R locations were collected from them. Colonic epithelial cell AJ protein expression and AJ structural changes in the tissues were detected using Western blot, immunofluorescence and transmission electron microscope (TEM). Results: (1)Both in I and R sites, the mRNA and protein expression of E-cad in IBS rats were both significantly lower than in normal SD rats (all P<0.05). The mRNA expression of β-cat showed no significant change in IBS SD rats compared with the normal SD rats; the protein expression of β-cat was decreased in I(P<0.05), no significantly different in R. (2)In I and R of IBS-D patients, the expression of E-cad protein were significantly decreased(I: 0.85±0.30 vs 1.24±0.34, P=0.00; R: 0.86±0.17 vs 1.14±0.48, P=0.05); the protein expression of β-cat also showed significant reduction both in I(0.85±0.39 vs 1.22±0.51, P=0.04)and R (0.92±0.22 vs 1.16±0.31, P=0.02) of IBS-D patients, compared with the healthy controls. Immunofluorescence results showed that E-cad and β-cat in colonic epithelial cells of I and R in the healthy controls were distributed along the cell membrane, demonstrating honeycomb linear fluorescence; however, in IBS-D patients, the structure of E-cad and β-cat were fuzzy, with disrupted distribution in the cytoplasm. Under TEM, the gaps of AJ in I and R of IBS-D patients appeared wider than in the healthy volunteers. Conclusions: In IBS-D patients, there are wider gaps of AJ, and decreased expression with structural disorder of E-cad and β-cat in the colon. The change of AJ plays an important role in the damage of colonic mucosal barrier and the increase of intestinal epithelial permeability in IBS-D patients, but the mechanism is yet to be further explored.

Abstract
Objective: To investigate potential value of fibrin related markers in patients with femoral fracture during perioperative period. Methods: Ninety-five patients were enrolled, including 39 males with (53±24) years old and 56 females with (73±13) years old, of which 44 fracture on caput femoris, 34 collum femoris and 17 shaft of femur. Sampling on the day before operation and 1(st,) 3(rd,) 5(th) days after operation, fibrin monomer (FM), D-dimer(DD), fibrinogen degradation product (FDP) and other coagulation assays were detected by reagents from Stago. Difference in day-to-day and between surgical sites were analyzed with general linear model (repeated measures). Results: FDP level on pre-operation, 1(st,) 3(rd,) 5(th) day after operation were 7.88(5.19, 12.12), 15.68(9.84, 29.48), 8.44 (6.27, 12.49) and 10.28 (7.56, 14.00) mg/L, the value of fibrin monomer were 5.00 (5.00, 6.03), 9.89(5.04, 30.12), 5.00 (5.00, 6.04) and 5.02(5.00, 5.76) mg/L. The value of D-Dimer were 2.24(1.41, 3.60), 4.78(2.74, 9.18), 2.60(1.79, 3.88) and 2.91(2.20, 3.85) mg/L, respectively, each parameter changs statistically during observation (Z=4.758, 6.027, 3.238 respectively, P<0.05). On the 5th day after surgery, fibrin monomer in patients with venous thrombus embolism (VTE) were higher than that in patients without VTE, 10.18(7.24, 28.11) mg/L vs 5.10(5.00, 6.73) mg/L (Z=-1.580, P<0.05), which showed potential value evaluating of post-operative VTE. No statistical changes were found in prothrombin time or thrombin time (TT) (P>0.05), but activated partial thromboplastin time (APTT) varied from day to day in (38.1±4.9), (40.8±5.2), (45.1±6.2) and (41.9±6.3)s with statistically difference (F=7.127, P<0.05). Similarly, fibrinogen changed statistically in (5.01±0.94), (4.99±1.35), (6.00±1.75), (5.81±1.38)g/L (F=8.927, P<0.05). Conclusion: Fibrin monomer, additional to markers as D-dimer, shows its value on activated coagulation associated to post-operative thromboembolism for patients receiving femoral surgery.

Abstract
Objective: To explore the prognostic factors for inability to walk independently in patients with multiple system atrophy (MSA). Methods: A total of 123 patients with clinically confirmed MSA admitted to Navy General Hospital and Dongfang Hospital affiliated to the Second Clinical Medical College of Beijing University of Chinese Medicine, from February 2013 to February 2016, were retrospectively reviewed. Clinical data and all records were collected and all subjects were followed up by a telephone call in February 2016. The second milestone of activities of daily living scale (ADL), defined as inability to walk independently, was taken as the primary outcome. Eight possible prognostic factors were investigated and the survival analysis was performed with Cox proportional hazards model regression. Results: Of all the MSA patients, 74 subjects were men and 49 were women with a sex radio of 1.51∶1(M∶F). Seventy cases were diagnosed with MSA-cerebellar type (MSA-C) and 53 with MSA-Parkinson type (MSA-P) (C∶P=1.32∶1). Mean age at the onset of first symptom was (53±8) years old. All patients had severe autonomic nervous dysfunction. At the last follow-up, 56 cases (45.5%) were unable to walk independently. The median survival time from the onset of MSA to inability to walk independently was 73 months. The age of onset ≥ 55 years (HR=1.969, 95%CI 1.095-3.542, P=0.024) and the interval time from disease onset to combined motor and autonomic involvement≤3 years (HR=2.308, 95%CI 1.158-4.600, P=0.017) were independent prognostic factors for inability to walk independently, while gender, MSA clinical subtypes, initial symptoms, alcohol intake, smoking and toxic exposure were not indicators for independent walking (P>0.05). Conclusions: The prognostic factors for inability to walk independently in patients with MSA are the age of onset ≥55 years and the interval time from disease onset to combined motor and autonomic involvement≤3 years. Although factors including gender, MSA clinical subtypes, initial symptoms, alcohol intake, smoking and toxic exposure are not the predictive factors for inability to walk independently in our MSA patients, their roles in the prognosis of MSA still need further investigation.

Abstract
OBJECTIVE To investigate the factors affecting the vaginal birth after cesarean (VBAC). METHODS Totaly 298 women who underwent trial of labor after cesarean section (TOLAC) from Jan 2015 to Dec 2015 were recruited from Beijing Obstetrics and Gynecology Hospital, FuXing Hospital, Tongzhou Maternal and Child Health Hospital of Beijing, the Second Affiliated Hospital of Chongqing Medical University and the People's Hospital of Chengyang District of Qingdao. The maternal age, the interval from the last cesarean section, the body mass index (BMI) before pregnancy, the weight gain during pregnancy, the way into labor, the Bishop score before labor, the gestational age and the birth weight of the neonate were recorded in a self-made form. The factors affecting VBAC were analyzed by univariate analysis and multivariable logistic regression. RESULTS (1)The incidence of VBAC, uterine rupture, postpartum hemorrhage and neonatal asphyxia were 70.5% (210/298), 2.7% (8/298), 9.4% (28/298) and 1.3% (4/298), respectively. No maternal death and perinatal death occurred. (2)The univariate analysis suggested that the maternal age, the BMI before pregnancy, the Bishop score before labor, the labor induction, the gestational age at delivery and the neonatal weight were factors affecting VBAC. The maternal age and the Bishop score before labor were significantly higher in the VBAC group than in the unsuccessful TOLAC group(P<0.05). While the BMI before pregnancy, the induction rate, the gestational weeks at delivery and the birth weight of the neonate were significantly lower in the VBAC group than in the unsuccessful TOLAC group (P<0.05). Multivariable logistic regression analysis showed that successful VBAC was affected by the maternal age, the BMI before pregnancy, the Bishop score before labor and the birth weight of the neonates(P<0.05). CONCLUSION The maternal age, the BMI before pregnancy, the Bishop score before labor and the birth weight of neonate are the main factors affecting VBAC.

Abstract
This study aims to determine the effects of alfalfa supplementation on the pre- and postweaning performance, rumen development, and feed transition in starter diet-fed lambs. Six of 66 male Hu lambs were slaughtered at the age of 10 d to serve as a control. The other 60 lambs were randomly allocated to 2 dietary treatments: milk replacer and starter pellets without (STA) or with free-choice chopped alfalfa (S-ALF). The animals were offered 300 g/d of the concentrate mixture and had free access to alfalfa after weaning at the end of wk 4 (age 38 d). The alfalfa inclusion in the S-ALF group tended to increase the starter intake before weaning, significantly increased the concentrate intake soon after weaning ( < 0.05), and increased the BW ( < 0.01) and ADG ( < 0.10) in pre- and postweaning lambs. The S-ALF group had heavier carcasses ( < 0.05), rumens ( < 0.05), reticula ( < 0.05), omasums ( < 0.10), abomasums ( < 0.05), and visceral organs ( < 0.10) than the STA lambs after weaning. Alfalfa supplementation increased ( < 0.05) the rumen papillae length and the ratio of the duodenal villus height to the crypt depth; it also decreased ( < 0.05) the concentration and molar proportion of propionate in wk 1 and 5. The STA lambs had higher ( < 0.01) blood concentrations of globulin and blood urea nitrogen and lower β-hydroxybutyrate after weaning. The STA group also had a higher incidence of feed plaque. From the above results, we infer that the free-choice addition of chopped alfalfa to starter diets is beneficial to rumen development, relieves weaning stress, and improves the performance of lambs.

Abstract
OBJECTIVE To evaluate the feasibility of applying AMPLATZER Vascular Plug Ⅱ (AVP Ⅱ) in transcatheter closure of congenital coronary artery fistula in children. METHOD Transcatheter closure procedure applying AVP Ⅱ was carried out in 7 patients (3 males and 4 females, age 1.2-12.0 years) with congenital coronary artery fistula between May 2014 and September 2015 in Pediatric Cardiology Department of Guangdong Cardiovascular Institute. Selective coronary artery angiography and aortic root angiography were performed after the release of the device to evaluate the immediate therapeutic effect. Echocardiography and electrocardiography were performed at 1 day, 1 month, 3 months, 6 months, 1 year post procedure and repeated once a year during the follow-up period. RESULT Transcatheter deployment of the device was successfully accomplished in all patients. The narrowest diameter of the fistula was (8.6±2.8) mm (4.0-12.5 mm), and the size of the deployed device ranged from 10.0 to 16.0 mm. Immediate selective coronary artery angiography revealed no residual shunt in 5 patients and trivial residual shunt in 2 patients. During a mean follow-up period of 2.7 (1.0-16.0) months, echocardiography showed that 3 patients remained no residual shunt, while 2 patients had trivial residual shunt, 2 patients developed small residual shunt. Cardiac murmur disappeared post procedure in all patients. Electrocardiography showed no ST-T changes. No migration or detachment of the device was found. CONCLUSION AVP Ⅱ is a safe and effective choice in transcatheter closure of congenital coronary artery fistula in children.

Abstract
OBJECTIVE To investigate the epidemiological features of heatstroke in Shaoxing, China in 2008-2014, and to provide a reference for developing prevention and control measures for heatstroke. METHODS The reports on heatstroke in Shaoxing in 2008-2014 were collected from the China Information System for Disease Control and Prevention, and the data were summarized and analyzed. RESULTS A total of 1 676 heatstroke cases were reported in Shaoxing in 2008-2014, among which 1 485 cases(88.6%) were mild heatstroke and 191 cases(11.4%) were severe heatstroke. Nine persons died of severe heatstroke, and the fatality rate was 0.5%(9/1 676). Among these persons, 4(44.4%, 4/9) were the elderly living at home, 4 (44.4%, 4/9) were farmers (working outdoors), and 1(11.2%, 1/9) was unemployed. The male patients with heatstroke accounted for 66.3%(1 111/1 676), and those with severe heatstroke accounted for 13.1%(146/1 111); the female patients with heatstroke accounted for 33.7%(565/1 676), and those with severe heatstroke accounted for 8.0%(45/565); there were significant differences between male and female patients(χ(2)=9.94, P=0.002). The mean age of patients with heatstroke was 48.7±18.8 years; the mean age of male patients was 49.8±17.9 years, and that of female patients was 46.6±20.3 years, with a significant difference between the male and female patients(t=3.19, P<0.001). Most of the patients experiencing heatstroke were in their forties or fifties, each accounting for 19.2%(321/1 676); in male patients who experienced heatstroke, those in their fifties accounted for the highest percentage(21.5%, 239/1 111), and in female patients who experienced heatstroke, those in their twenties accounted for the highest percentage (18.9%, 107/565). Based on stratification by age, the severity of heatstroke differed significantly between male and female patients in their forties, fifties, sixties, seventies, and eighties(P<0.05). Most of the cases of heatstroke occurred in June to September, accounting for 98.9%(1 657/1 676), particularly in July and August, accounting for 87.1%(1 460/1 676). CONCLUSION In Shaoxing, heatstroke usually occurs in summer, and most cases are mild. Middle-aged and elderly men and farmers(working outdoors) are susceptible to heatstroke, and warnings on heatstroke and emergency treatment of severe heatstroke should be enhanced.
