Abstract
Objective: To investigate China statistics of extracorporeal life support (ECLS) in 2018. Methods: The statistics data was collected by provincial coordinators assigned by Chinese Society of Extracorporeal Life Support (CSECLS) in 2019, including cases, centers, indications, and in-hospital survival rate. Results: Three thousand nine hundred and twenty-three cases were reported by 260 ECLS centers. There were an increase of 38.8% in extracorporeal membrane oxygenation (ECMO) cases and an increase of 11.6% in ECMO centers compared with that in 2017 (2 826 cases and 233 centers). Adult, pediatric, and neonatal patients accounted for 88.0%, 9.7%, and 2.3% of total cases, respectively. Centers with more than 20 ECMO cases per year had favorable in-hospital survival rate compared with those less than 20 cases (49.1% vs 44.0%, P=0.005). ECMO cases (r=0.71, P<0.001) and centers (r=0.81, P<0.001) were both associated with regional gross domestic product. Conclusions: There was a growth in ECLS cases, centers, and center scale in China within 2018. The majority of ECLS cases and centers were in developed regions. The ECLS indications, and in-hospital mortality in China were in accordance with that in the Extracorporeal Life Support Organization registry gradually. Large-scale ECLS centers had favorable patient outcomes. The development of ECLS still has tremendous potential in China, especially for pediatric and neonatal patients.

Abstract
The aim of the present study was to investigate the effects of alisol B 23‑acetate (AB23A) on inhibiting the viability and inducing apoptosis of human non‑small cell lung cancer (NSCLC) cells and the anticancer mechanisms of AB23A in vitro. The viability of A549 cells following treatment with different doses of AB23A was examined using a Cell Counting Kit‑8 assay. Subsequently, apoptosis and the cell cycle were detected using flow cytometric analysis. The effect of AB23A on migration and invasion of A549 cells was detected by wound healing and Transwell assays. Western blotting was performed to determine the relative expression of Bax/Bcl‑2, phosphatidylinositol 3‑kinase (PI3K), protein kinase B (AKT) and mammalian target of rapamycin (mTOR). AB23A markedly inhibited the viability enhanced apoptosis of A549 cells and arrested the cell cycle in G1 phase. Additionally, AB23A upregulated the ratio of Bax/Bcl‑2 in the A549 cells in a concentration‑dependent manner. The results of wound healing and Transwell assays indicated that AB23A also suppresses the migration and invasion ability of A549 cells. Furthermore, AB23A reduced the protein levels of phosphorylated AKT, PI3K and mTOR. In conclusion, AB23A exerted anti‑cancer activity via inhibiting cells viability, migration and invasion, and promoting apoptosis. Therefore, AB23A is a potential antitumor drug for the treatment of NSCLC.

Abstract
Objective: To analyze the correlation between endogenous EPO levels and electrocardiogram scatter plot changes in patients with coronary heart disease and autonomic nerve function injury. Methods: Forty-eight patients who underwent coronary arteriography (CAG) inspection due to chronic coronary heart diseases were selected from July 2015 to October 2015. All of them were evaluated by the Ewing standard autonomic nervous function test, and were divided into Ewing(+) group and Ewing(-) group according to the results of the test. The clinical data of the patients was collected and venous blood was extracted to detect EPO level. Results: The EPO level of Ewing (+) group ((13±3) mIU/ml) was significantly higher than that of Ewing (-) group ((10±3) mIU/ml). The Lorenz scatter plot comet shapes between the two groups had a significant difference. As for the quantitative indicators of Lorenz scatterplot, length of the Ewing (+) group ((147±22) ms) was shorter than that of the Ewing (-) group ((164±24) ms) and there was no significant differences in the width between the two groups. EPO level was negatively correlated with length in both groups (r=-0.427, P=0.002), but not with width (r=0.091, P=0.539). Binary logistic regression analysis showed that EPO (OR=1.394) and diastolic blood pressure (OR=1.091) were risk factors for autonomic nervous function damage. Length (OR=0.934) was a protective factor for autonomic nervous function. ROC curve analysis showed that the area under the EPO curve was 0.737 and that under the length curve was 0.719. Conclusions: The endogenous EPO levels are associated with the changes of electrocardiogram scatter plot in patients with coronary heart disease and autonomic nerve function injury. EPO and length of scatter plot have the similar diagnostic value on predicting of autonomic nerve function injury.

Abstract
Objective: To investigate the influence of occupational stress on recurrent spontaneous abortion (RSA) in women of childbearing age. Methods: From January to December, 2017, 75 working women of childbearing age (25-35 years) who were admitted to a provisional hospital in Lanzhou, China and diagnosed with RSA were assigned into patient group. At a 1∶4 ratio, 300 age-matched working women who had normal first pregnancy were randomly selected as controls. A case-control study was conducted by a self-made questionnaire and the effort-reward imbalance scale. The impact of occupational stress on RSA in women of childbearing age was analyzed by evaluation of occupational harmful factors, regularity, effort-reward ratio, and sleep quality. Results: There were significant differences in the distribution of sleep, daily exercise, night shift, extrinsic-effort/low-reward score, and effort/low-reward score between the patient group and the control group (χ(2)=7.867, P<0.05; χ(2)=7.377, P<0.05; χ(2)=3.714, P<0.05; χ(2)=6.651, P<0.05; χ(2)=8.556, P<0.05) . With controlled factors such as general conditions and living habits, logistic regression analysis showed that poor sleep quality and high-effort/low-reward were risk factors for RSA (odds ratio[OR]=1.462, 95% confidence interval[CI]: 1.032~2.073; OR=3.253, 95%CI: 1.169~9.053) . A regular work was a protective factor against RSA (OR=0.644, 95%CI: 0.438-0.946) . Conclusion: In occupational stress, irregular working hours, lack of sleep, and high-effort/low-reward are risk factors for RSA. Working women of childbearing age should ensure adequate sleep, pay attention to effort-reward balance, and make a regular work schedule.

Abstract
Objective: To survey the conduction and evaluate the effectiveness of extracorporeal membrane oxygenation (ECMO) therapy in pediatric intensive care unit (PICU) in China mainland. Methods: In a questionnaire-based survey, we retrospectively reviewed the application of ECMO in children's hospital and general hospital in China mainland to summarize and analyze the categories of diseases and prognosis of children treated with ECMO therapy. Results: By December 31, 2017, a total of 23 hospitals using ECMO, including 22 tertiary referral hospitals and 1 secondary hospital, among which 16 were children's hospitals and 7 were general hospitals. Thirty-seven ECMO equipment was available. A total of 518 patients treated with ECMO, within whom 323 (62.4%) successfully weaned from ECMO and 262 (50.6%) survived to discharge. Among 375 pediatric patients, 233 (62.1%) were successfully weaned from ECMO and 186 (49.6%) survived to discharge. Among 143 newborn patients, 90 (62.9%) successfully weaned from ECMO, 76 (53.1%) survived to discharge. ECMO was applied in veno-arterial (VA) mode to 501 (96.7%) patients, veno-venous (VV) mode to 14 (2.7%) patients, and VV-VA conversion mode to 3 (0.6%) patients. Sixty-nine patients required extracorporeal cardiopulmonary resuscitation (ECPR), including 20 newborn patients (29.0%) and 38 pediatric patients (71.0%), who were all with cardiovascular disease. Neonatal respiratory distress syndrome (26/61), persistent pulmonary hypertension of the newborn (PPHN) (12/61), and meconium aspiration syndrome (MAS) (11/61) are the most common pulmonary diseases in newborn patients; among whom, infants with PPHN had highest survival rate (10/12), followed by MAS (9/11). Among newborn patients with cardiovascular diseases, those who admitted were after surgery for congenital cardiac disease were the most common (54/82), while those with septic shock had the highest survival rate (2/3). In pediatric pulmonary diseases, acute respiratory distress syndrome was the most common (42/93), while plastic bronchitis was with the highest survival rate (4/4), followed by viral pneumonia (13/16). Among pediatric cardiovascular diseases, congenital cardiac defect was the most common (124/282), while fulminant myocarditis had the highest survival rate (54/77). Conclusion: The application of ECMO as a rescue therapy for children with severe cardiopulmonary failure has dramatically developed in China mainland.

Abstract
OBJECTIVES To observe the changes of the formation time of venous thrombus in rats, and to provide new ideas and methods for the estimation on thrombus formation time of the forensic cases died from thrombosis. METHODS Totally 80 rats were randomly divided into 10 groups (0 h, 3 h, 6 h, 12 h, 1 d, 3 d, 1 week, 2 weeks, 3 weeks and 4 weeks after operation). A vein thrombosis model was established by the "narrow" method. The processes of thrombosis, organization, recanalization and the features of change on hemosiderin and calcium salt were observed by HE stain, Perls stain and Von Kossa stain. The expression changes of CD61, α-SMA and CD34 were observed by immunohistochemical staining technique. RESULTS Platelets adhered to the exposed blood vessel intima 3 h after operation, and platelet trabeculae were formed by the repeated accumulation of platelets 1 d after operation. The thrombus organization formed through the fibroblasts from vessel wall that grew into the interior of the thrombus 3 d after operation. Endothelial cells covered the surface of thrombus and then the new blood vessels were reformed, and the vessels were reconstructed. The expression of CD61 upregulated at the stages of the thrombus formation (3 h) and thrombus reformation (4 weeks), and reached the peak 1 d after thrombus formation. The release of hemosiderin and the initial expression of α-SMA were detected 3 d later. Calcium deposit and expression of CD34 were observed 1 week later. CONCLUSIONS The hemosiderin, calcium salt, CD61, α-SMA and CD34 show time-dependent changing characteristics, which is expected to provide a reference for the estimation on thrombus formation time of the forensic cases died from thrombosis.

Abstract
Objective: The aim was to investigate the genotype distribution of two major epitopes of large surface protein (PreS1) of hepatitis B in Chinese patients and to explore the association between the genotypes of these two epitopes, and to determine whether PreS1 full-length genotype could be revealed according to the polypeptide sequence of key epitopes. Methods: HBV DNA was extracted from the serum of patients for PCR amplification. 278 samples amplified successfully were sequenced and compared with the known HBV sequences in Genbank to determine the two key epitopes of HBV PreS1 genotype (amino acid epitope 21-47 and 94-117, abbreviated as P21 and P94) and PreS1 full-length genotypes. The correlation among three genotyping approaches was analyzed by Cohen's kappa coefficient to verify the consistency between the key-epitope genotyping and the full-length preS1 genotyping. Results: 232 samples were successfully sequenced. The genotyping based on the kind of P21 epitope protein sequence, 201 cases for genotype C, 23 cases for genotype B and 8 cases for uncertain genotypes and genotyping based on the form of P94 epitope protein sequence, 199 cases for genotype C, 25 cases for genotype B and 8 cases for indeterminate genotypes. Lastly, the genotyping based on sequence of the full-length PreS1 sequence, 207 and 25 cases for genotype C and B. P21 or P94 epitope genotyping and PreS1 full length genotyping were highly consistent, respectively, 96.55% and 96.12%, and the two epitopes (P21and P94) genotyping have parallel consistency (93.10%). Conclusion: In this study, an innovatively genotyping method based on the amino acid sequence of key epitopes was proposed. The genotypes of HBV in china were mainly B and C genotypes, and the genotypes of key conserved epitopes of HBV PreS1 were highly consistent with the full-length genotyping ( > 96%). Moreover, genotyping with one or two key epitopes can be used in place of the full-length genotyping.

Abstract
The dissipation of triforine in the immature and mature fruit periods was investigated under field conditions. Residue levels of triforine in watermelon were determined by gas chromatography with an electron capture detector (GC-ECD). The decline curves of triforine residues in the watermelon corresponded with first-order kinetics. The half-lives of triforine in Dark Belle and Shiny Boy were 2.10-2.57 days and 2.31-2.67 days respectively. Meanwhile, the half-lives of triforine in the immature and mature fruit periods were 1.69-2.04 days and 2.89-3.85 days, respectively. In the terminal residue experiment, the terminal residues of triforine in the watermelon flesh and peel were below 0.01 mg/kg to 0.05 mg/kg and 0.03 mg/kg to 0.36 mg/kg, respectively. The dissipation rates of triforine varied in different cultivars of watermelon, and even in the same cultivar, the half-lives of triforine significantly varied in the different fruit periods. Although triforine is a fungicide within the suction, the terminal residues in the peel and flesh were very significant.

Abstract
The aquatic plant Hydrocotyle vulgaris was evaluated for its efficacy in removing prometryn from nutrient solution. Under optimized experimental conditions, up to 94.0% of the initial prometryn was removed from the hydroponic culture medium by H. vulgaris in 30 days. The concentration of prometryn decreased from the initial level of 0.55 ± 0.013 mg/L to 0.036 ± 0.001 mg/L at the end of the experimental period. The removal kinetics followed first-order kinetic equation (Ct = 0.4569e-0.09t). Half-life (t1/2) of prometryn was greatly shortened from 27.16 days (without plant) to 5.58 days (with H. vulgaris). Approximately 22% of the initial prometryn residue was found in H. vulgaris tissue, while 11.7% was degraded by the plant in 30 days. The metabolites of prometryn detected were 2,4-diamino-1,3,5-triazine (in the hydroponic culture medium) and 2,4,6-trihydroxy-1,3,5-triazine (in plant tissue) after 30 days. The results indicate that H. vulgaris can be used for phytoextraction of prometryn and could potentially be effective in removing other s-trazine pesticides from contaminated aquatic ecosystems.

Abstract
Objective: To analyze the spatial distribution and identify the high risk areas of pulmonary tuberculosis at the township level in Beijing during 2005-2015. Methods: Data on pulmonary tuberculosis cases was collected from the tuberculosis information management system. Global autocorrelation analysis, local indicators of spatial association and Kulldorff's Scan Statistics were applied to map the spatial distribution and detect the space-time clusters of the pulmonary tuberculosis cases during 2005-2015. Results: Spatial analysis on the incidence of pulmonary tuberculosis at the township level demonstrated that the spatial autocorrelation was positive during the study period. The values of Moran's I ranged from 0.224 3 to 0.291 8 with all the P values less than 0.05. Hotspots were primarily distributed in 8 towns/streets as follows: Junzhuang, Wangping, Yongding and Tanzhesi in Mentougou district, Yancun in Fangshan district, Wangzuo town in Fengtai district, Tianqiao street in Xicheng district and Tianzhu town in Shunyi district. Spatiotemporal clusters across the entire study period were identified by using Kulldorff's spatiotemporal scan statistic. The primary cluster was located in Chaoyang and Shunyi districts, including 17 towns/streets, as follows: Cuigezhuang, Maizidian, Dongfeng, Taiyanggong, Zuojiazhuang, Hepingjie, Xiaoguan, Xiangheyuan, Dongba, Jiangtai, Wangjing, Jinzhan, Jiuxianqiao, Laiguangying, Sunhe towns/streets in Chaoyang district, Houshayu and Tianzhu town in Shunyi district, during January to December 2005. Conclusion: Incidence rates of pulmonary tuberculosis displayed spatial and temporal clusterings at the township level in Beijing during 2005-2015, with high risk areas relatively concentrated in the central and southern parts of Beijing.

Abstract
OBJECTIVES Pits and fissures sealing with flowable materials is a popular method for preventing caries in preventive dentistry while there is still microleakage existed. This in vitro study aimed to explore the effects of subpressure technique on the sealing ability of pit and fissure sealant. MATERIALS AND METHODS One hundred and forty-one extracted human premolars were collected in this study and treated with different pressure (atmosphere pressure as group C, -0.04 MPa as group S4 and -0.08 MPa as group S8). Thermocycling (×5000) was also performed. Penetration percentage, microleakage, cross-sectional microhardness (Knoop, KMH) and mineral loss were evaluated. Kappa tests, Friedman nonparametric and two-way ANOVA were used for data analysis. RESULTS Penetration percentages of group S4 and S8 were significant higher compared to that of group C. Microleakage of groups was similar before thermocycling, while subpressure groups showed lower scale of microleakage after thermocycling. Data of KMH and mineral loss showed significant differences between subpressure and thermocycling groups. SIGNIFICANCE Subpressure technique could increase the penetration of pit and fissure sealant, decrease microleakage and increase resistance of demineralization after thermocycling. This novel technique may have great potential for preventing from secondary caries.

Abstract
An inflammatory myofibroblastic tumour is a mesenchymal neoplasm that mostly involves the lung and rarely involves the oesophagus. Surgery has been most commonly used for the treatment of oesophageal inflammatory myofibroblastic tumours but there are no definite guidelines for their diagnosis and treatment. We describe the case of a 60-year-old woman presenting with dysphagia and poor appetite who was diagnosed with a submucosal oesophageal tumour by contrast enhanced computed tomography and ultrasonography endoscopy. She was treated successfully by endoscopic submucosal dissection with no complications. The final diagnosis was confirmed by pathological examination.

Abstract
To establish the experts consensus on the right heart function management in critically ill patients. The panel of consensus was composed of 30 experts in critical care medicine who are all members of Critical Hemodynamic Therapy Collaboration Group (CHTC Group). Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. Then the Delphi method was adopted by 52 experts to reassess all the statements. (1) Right heart function is prone to be affected in critically illness, which will result in a auto-exaggerated vicious cycle. (2) Right heart function management is a key step of the hemodynamic therapy in critically ill patients. (3) Fluid resuscitation means the process of fluid therapy through rapid adjustment of intravascular volume aiming to improve tissue perfusion. Reversed fluid resuscitation means reducing volume. (4) The right ventricle afterload should be taken into consideration when using stroke volume variation (SVV) or pulse pressure variation (PPV) to assess fluid responsiveness.(5)Volume overload alone could lead to septal displacement and damage the diastolic function of the left ventricle. (6) The Starling curve of the right ventricle is not the same as the one applied to the left ventricle,the judgement of the different states for the right ventricle is the key of volume management. (7) The alteration of right heart function has its own characteristics, volume assessment and adjustment is an important part of the treatment of right ventricular dysfunction (8) Right ventricular enlargement is the prerequisite for increased cardiac output during reversed fluid resuscitation; Nonetheless, right heart enlargement does not mandate reversed fluid resuscitation.(9)Increased pulmonary vascular resistance induced by a variety of factors could affect right heart function by obstructing the blood flow. (10) When pulmonary hypertension was detected in clinical scenario, the differentiation of critical care-related pulmonary hypertension should be a priority. (11) Attention should be paid to the change of right heart function before and after implementation of mechanical ventilation and adjustment of ventilator parameter. (12) The pulmonary arterial pressure should be monitored timingly when dealing with critical care-related pulmonary hypertension accompanied with circulatory failure.(13) The elevation of pulmonary aterial pressure should be taken into account in critical patients with acute right heart dysfunction. (14) Prone position ventilation is an important measure to reduce pulmonary vascular resistance when treating acute respiratory distress syndrome patients accompanied with acute cor pulmonale. (15) Attention should be paid to right ventricle-pulmonary artery coupling during the management of right heart function. (16) Right ventricular diastolic function is more prone to be affected in critically ill patients, the application of critical ultrasound is more conducive to quantitative assessment of right ventricular diastolic function. (17) As one of the parameters to assess the filling pressure of right heart, central venous pressure can be used to assess right heart diastolic function. (18). The early and prominent manifestation of non-focal cardiac tamponade is right ventricular diastolic involvement, the elevated right atrial pressure should be noticed. (19) The effect of increased intrathoracic pressure on right heart diastolic function should be valued. (20) Ttricuspid annular plane systolic excursion (TAPSE) is an important parameter that reflects right ventricular systolic function, and it is recommended as a general indicator of critically ill patient. (21) Circulation management with right heart protection as the core strategy is the key point of the treatment of acute respiratory distress syndrome. (22) Right heart function involvement after cardiac surgery is very common and should be highly valued. (23) Right ventricular dysfunction should not be considered as a routine excuse for maintaining higher central venous pressure. (24) When left ventricular dilation, attention should be paid to the effect of left ventricle on right ventricular diastolic function. (25) The impact of left ventricular function should be excluded when the contractility of the right ventricle is decreased. (26) When the right heart load increases acutely, the shunt between the left and right heart should be monitored. (27) Attention should be paid to the increase of central venous pressure caused by right ventricular dysfunction and its influence on microcirculation blood flow. (28) When the vasoactive drugs was used to reduce the pressure of pulmonary circulation, different effects on pulmonary and systemic circulation should be evaluated. (29) Right atrial pressure is an important factor affecting venous return. Attention should be paid to the influence of the pressure composition of the right atrium on the venous return. (30) Attention should be paid to the role of the right ventricle in the acute pulmonary edema. (31) Monitoring the difference between the mean systemic filling pressure and the right atrial pressure is helpful to determine whether the infusion increases the venous return. (32) Venous return resistance is often considered to be a insignificant factor that affects venous return, but attention should be paid to the effect of the specific pathophysiological status, such as intrathoracic hypertension, intra-abdominal hypertension and so on. Consensus can promote right heart function management in critically ill patients, optimize hemodynamic therapy, and even affect prognosis.

Abstract
Primary biliary cholangitis (PBC) is an autoimmune liver disease mainly involving intrahepatic interlobular bile ducts and can progress to liver fibrosis, liver cirrhosis, and even liver failure. Ursodeoxycholic acid (UDCA) is the first-line therapeutic drug for PBC and can delay disease progression, but as high as 40% of patients have suboptimal response to UDCA. Obeticholic acid, a farnesoid X receptor agonist, has been approved by FDA in May 2016 for patients who have no response to UDCA treatment or cannot tolerate such treatment. Other drugs such as fibrates, glucocorticoids, immunosuppressants, biological agents, and mesenchymal stem cells are gradually used in clinical practice and bring new hope to patients with refractory PBC.

Abstract
Objective: To study the etiological, clinical, radiological, diagnostic, therapeutic, and prognostic manifestations of exogenous lipoid pneumonia (ELP), and therefore to improve the diagnosis and treatment of this disease. Methods: The clinical data of 12 cases of ELP confirmed by pathology were retrospectively analyzed. Results: The patients consisted of 9 males and 3 females, with an average age of 73.8 years (range, 44 to 100 years). The underlying diseases were variable, including diseases affecting the general condition (multiple organ failure, chronic heart and renal insufficiency, pemphigoid, etc) and conditions with increased risk of aspiration (sequelae of cerebrovascular disease, Alzheimer's disease, advanced stage of nasopharyngeal carcinoma, paralytic ileus, etc). The 12 cases were all caused by Inhalation of mineral oil. Common symptoms included cough, sputum production and dyspnea. ELP had no special physical signs. Inflammation indexes, such as white blood cell, neutrophil percentage, ESR, C reactive protein, procalcitonin, D-Dimer, and blood lipid levels were usually normal. Radiological features of ELP mainly included consolidation, mass or nodules, with a little ground-glass opacity. Some patients had ventilation and/or diffusion dysfunction. The diagnostic methods included CT-guided percutaneous lung biopsy, thoracoscopy, thoracotomy or autopsy. Histopathological findings showed accumulation of large foamy macrophages in the alveolar spaces, with a few lipid deposition and polykaryocytes. The main treatment of ELP was cessation of lipid material contact. One case died of ELP, 6 died of other coexisting diseases, and the rest 6 improved with treatment and were discharged. The survival patients were all stable during a follow-up of 2-4.5 years. Conclusions: ELP was rare and its clinical manifestation was atypical. Its radiological manifestations were indistinguishable from pneumonia, lung cancer, interstitial lung diseases, etc. Pathological examination was the gold standard for diagnosis, and the preferred means of sampling was bronchoscopy. In cases whose diagnosis could not be confirmed by BALF, CT-guided percutaneous lung biopsy might be considered. The most important treatment is cessation of lipid material contact. The prognosis is good.

Abstract
Objective: To compare the safety and efficacy of insulin degludec (IDeg) with those of insulin glargine (IGlar) in insulin-naive subjects with type 2 diabetes (T2DM). Methods: This was a 26-week, randomized, open-label, parallel-group, treat-to-target trial in 560 Chinese subjects with T2DM (men/women: 274/263, mean age 56 years, mean diabetes duration 7 years) inadequately controlled on oral antidiabetic drugs (OADs). Subjects were randomized 2∶1 to once-daily IDeg (373 subjects) or IGlar(187 subjects), both in combination with metformin. The primary endpoint was changes from baseline in glycosylated hemoglobin(HbA1c) after 26 weeks. Results: Mean HbA1c decreased from 8.2% in both groups to 6.9% in IDeg and 7.0% in IGlar, respectively. Estimated treatment difference (ETD) of IDeg-IGlar in change from baseline was -0.10% points (95%CI-0.25-0.05). The proportion of subjects achieving HbA1c<7.0% was 56.3%and 49.7% with IDeg and IGlar, respectively [estimated odds ratio of IDeg/IGlar: 1.26(95%CI 0.88-1.82)]. Numerically lower rateof overall confirmed hypoglycaemia and statistically significantly lower nocturnal confirmed hypoglycemia were associated with IDeg compared with IGlar, respectively [estimated rateratio of IDeg/IGlar 0.69(95%CI 0.46-1.03), and 0.43(95%CI 0.19-0.97)]. No differences in other safety parameters were found between the two groups. Conclusions: IDeg was non-inferior to IGlar in terms of glycaemic control, and was associated with a statistically significantly lower rate of nocturnal confirmed hypoglycaemia. IDeg is considered to be suitable for initiating insulin therapy in Chinese T2DM patients on OADs requiring intensified treatment. Clinical trail registration: Clinicaltrials.gov, NCT01849289.

Abstract
Objective: To determine the basal metabolic rate (BMR) of young adults aged between 20-29 years old in Changsha. Methods: We recruited volunteers to join in our research project from April to May, 2015. All recruited volunteers must meet the inclusion criteria: aged 20-29 years old, height between 164-180 centimeters in males and 154-167 centimeters in females, in good health condition, and with no habit of regular physical exercise in last year. Finally, 81 qualified volunteers were selected as research objects, including 43 males and 38 females. The BMR, resting lying metabolism rate and resting sitting metabolism rate of the subjects were detected, and the determined BMR was compared with the calculated results: from the adjusted Schofield equation. Results The BMR, resting lying metabolism rate and resting sitting metabolism rate among males were (166.10±22.09), (174.22±24.56), and (179.54±23.35) kJ·m(-2)·h(-1), respectively, which were all higher than those among females were (137.70±20.04), (149.79±19.25), and (167.78±26.02) kJ·m(-2)·h(-1), respectively, (P<0.001). The BMR of males and females calculated from the adjusted Schofield equation were (160.83±3.93), and (140.29±4.18) kJ·m(-2)·h(-1), respectively, and there was no significantly statistical difference found between the determined BMR and the calculated results from Schofield equation (adjusted) classified by sex, all P values >0.05. Conclusion: The BMR of young adults aged 20-29 years old in Changsha was in the national average level, and the adjusted Schofield equation displayed fine accuracy in predicting BMR of young adults aged 20-29 years old in Changsha.

Abstract
Objective: To evaluate and compare the efficacy between posterior fossa decompression without duraplasty (PFD) and posterior fossa decompression with duraplasty (PFDD) in the surgical management for adult Chiari Ⅰ malformation. Methods: Fifty-seven patients suffered from Chiari malformation type Ⅰ were treated in Department of Neurosurgery, Henan Provincial People's Hospital from August 2008 to October 2013. Twenty-three patients received posterior fossa decompression without duraplasty and the other 34 patients received posterior fossa decompression with duraplasty. The clinical results were retrospectively analyzed to compare the efficacy of two different surgical approaches. Results: There was no death or severe neurological dysfunction case in 57 patients of the two groups. Patients undergoing PFD had shorter length of hospital stay[(13.7±3.5) d vs (16.2±4.1) d, P<0.05]and surgical time[(98.7±22.1) min vs (132.3±39.6)min, P<0.05]. Cerebrospinal fluid-related complications and intracranial infection were more common in patients undergoing PFDD[(0/23, 0) vs (8/34, 23.5%), P<0.05]. Clinical improvement was comparable in two groups[(15/23, 65.2%) vs (26/34, 76.5%), P>0.05]at the one-year follow-up. The rate of syrinx regression in patients with Syringomyelia was higher in patients undergoing PFDD[(3/12, 25%) vs (17/22, 77.3%), P<0.05]. Conclusion: For adult patients with Chiari malformation type Ⅰ, PFD has the advantages of simple manipulation, short length of hospital stay and low incidence of cerebrospinal fluid-related complications and intracranial infection, compared with PFDD. It is comparable to PFDD in clinical improvement, but the effect of PFD is not as good as that of PFDD in the aspect of syrinx regression.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has become the most important liver disease in the world and its prevalence rate still tends to increase. However, there are still no effective drugs so far. The complex and dynamic interactions between multiple effects/mediators in the pathophysiology of NAFLD provide new insights and help with stratification and redefinition of clinical phenotypes and evaluation of disease susceptibility and multiplicity of progression. They may also provide new targets for future treatment. Therefore, research on the pathophysiology of NAFLD is imperative. Alcoholic liver disease is a great harm to health and an important cause of end-stage liver disease. Some progress has been made in the research on alcoholic liver disease around the world in 2016. This article reviews the research advances in alcoholic liver disease in 2016 from the aspects of epidemiology, pathogenesis, diagnostic and therapeutic methods, and prognosis.

Abstract
OBJECTIVES To explore the expression and clinical significance of IncRNA-UCA1 in ovarian cancer. MATERIALS AND METHODS The ex- pression of IncRNA-UCA1 in 26 ovarian cancer tissue and 16 normal and benign ovarian tissue were detected using qRT-PCR method, and the correlation of expression level with clinicopathological features were analyzed. RESULTS Higher lncRNA-UCA1 expression level were detected in ovarian cancer tissue than those in normal ovarian tissue (p < 0.05). There were significant correlations between higher expression of IncRNA-UCA1 with tumor staging (p = 0.000), histological grades (p = 0.000), peritoneal effusion (p = 0.001), and lymph node metastasis (p = 0.000), but not with age. CONCLUSION IncRNA-UCA1 may play a vital role in the metastasis of ovarian cancer and it is expected to be a potential novel biomarker and therapeutic target of ovarian cancer.

Abstract
Autotransplantation of the submandibular gland is a potential treatment for severe kerato-conjunctivitis sicca. However, one of the major barriers to this procedure is that secretions from the transplanted gland decrease shortly after the operation, which may lead to obstruction of Wharton’s duct, or even to transplantation failure. Using a rabbit model, we investigated whether phenylephrine could improve the secretion from the transplanted gland. We found that phenylephrine treatment significantly reversed the decrease in salivary secretion after transplantation, enhanced the expressions of α1A-, α1B-, and α1D-adrenoceptor mRNA, and ameliorated atrophy of acinar cells. Furthermore, phenylephrine also induced translocation of aquaporin-5 from the cytoplasm to the apical membrane, and increased the levels of phospho-ERK1/2, ERK1/2, phospho-PKCζ, and PKCζ in the transplanted gland. These results indicate that phenylephrine treatment moderates structural injury and improves secretory function in the transplanted submandibular gland through promoting α1-adrenoceptor expression and post-receptor signal transduction.

Abstract
OBJECTIVE To compare the preliminary clinical outcomes of fenestration discectomy associated with annulus repair (FDAR) and fenestration discectomy (FD) for lumbar disc herniation in the adolescents. METHODS The data of 26 adolescent patients with single segment lumbar disc herniation who were admitted to the Department of Orthopedics, Xuzhou Central Hospital from October 2012 to October 2014 were retrospectively studied. All patients were divided into 2 groups, including 12 patients undergoing FDAR and 14 patients undergoing FD respectively. The factors including the length of skin incision, amount of intraoperative bleeding, operation time and duration of hospitalization were compared. The indentation of dura were measured from MRI. Pfirrmann grading system was used for assessment of lumbar disc degeneration preoperatively and 1 year later. The visual analogue scale (VAS), the oswestry disability index (ODI) and Japanese Orthopedic Association (JOA) scores were used to measure the clinical outcomes. Simultaneously, surgical complications, and postoperative recurrence of lumbar disc herniation were recorded. RESULTS There were no significant differences in the observational factors such as the skin incision length, amount of intraoperative bleeding, operation time, and duration of hospitalization between the FDAR and FD groups (P>0.05). The indentation of the dura significantly reduced after surgery in each group [FDAR: (7.3±2.6) vs (1.3±0.8) mm; FD: (7.4±3.1) vs (2.9±0.7) mm; both P<0.05]. The postoperative lumbar disc degeneration in FDAR group was the same as that of in FD group. The postoperative VAS scores and ODI scores at each follow-up time point in both groups were significantly improved when compared with the preoperative ones (P<0.05). There were no statistically significant differences between the 2 groups in the JOA score improvement rate (FDAR: 88.5%, FD: 87.2%; P>0.05). According to the modified MacNab criteria, there were no statistically significant differences between the 2 groups in the excellent and good rate (FDAR: 89.3%, FD: 88.5%; P>0.05). There were no dural tears, disc space infection, hematoma formation in the spinal canal and other serious complications in both groups. But there was one patient regaining the back and leg pain in the FD group, whereas recovering by conservative treatment. CONCLUSION The preliminary clinical efficacy of both FDAR and FD in the treatment of single segment lumbar disc herniation in the adolescents is satisfactory.

Abstract
OBJECTIVE To investigate the causes and strategies for intraoperative rupture during clipping the anterior circulation aneurysms. METHODS Nineteen patients with anterior circulation aneurysms ruptured during clipping, who admitted to the Department of Neurosurgery, Henan Provincial People's Hospital from November 2012 to February 2014, were enrolled. Their clinical data were analyzed retrospectively to summarize the causes and strategies for intraoperative rupture. RESULTS The aneurysms ruptured during predissection in 2 cases (10.5%), during dissection in 11 cases (57.9%) and during clip application in 6 cases (31.6%). There was no residual aneurysm confirmed by postoperative CTA in 17 patients. One case with posterior communicating artery aneurysm cannot be clipped because of the serious avulsion of the aneurysm neck during clipping. The aneurysm was trapped and the patient paralysed on one side after operation. One case died postoperative 8 days because of severe cerebral edema, whose aneurysm ruptured during predissection. The Glasgow Outcome Scale (GOS) of three months after operation showed good recovery in 11, moderate recovery in 5, severe disability in 2, and death in 1 cases, respectively. CONCLUSION Adequate preoperative evaluation for the risk factors of intraoperative rupture and excellent microsurgical techniques can prevent intraoperative rupture of intracranial aneurysms. Controlling the bleeding quickly and dissecting and clipping the aneurysm after definitely know the anatomy of the aneurysm and surrounding vasculature could be the keys to deal with intraoperative aneurysm rupture.

The objectives of the present study were to characterize the tissue expression of chicken (Gallus gallus) bone morphogenetic protein 4 (BMP4) and compare differences in its expression in abdominal fat tissue and serum between fat and lean birds and to determine a potential relationship between the expression of BMP4 and abdominal fat tissue growth and development. The results showed that chicken BMP4 messenger RNA (mRNA) and protein were expressed in various tissues, and the expression levels of BMP4 transcript and protein were relatively higher in adipose tissues. In addition, the mRNA and protein expression levels of BMP4 in abdominal fat tissue of fat males were lower than those of lean males at 1, 2, 5, and 7 wk of age (P < 0.05). Furthermore, the serum BMP4 content of fat males was lower than that of lean males at 7 wk of age (P < 0.05). BMP4 mRNA expression levels were significantly higher in preadipocytes than those in mature adipocytes (P < 0.05), and the expression level decreased during differentiation in vitro (P < 0.05). These results suggested that chicken BMP4 might affect abdominal fat deposition through differences in its expression level. The results of this study will provide basic molecular information for studying the role of BMP4 in the regulation of adipogenesis in avian species.

Abstract
2,4-bis(Isopropylamino)-6-methylthio-s-triazine (prometryn) poses a risk to aquatic environments in several countries, including China, where its use is widespread, particularly due to its chemical stability and biological toxicity. Vetiver grass (Chrysopogon zizanioides L.) was tested for its potential for phytoremediation of prometryn. Vetiver grass was grown in hydroponic media in a greenhouse, in the presence of prometryn, with appropriate controls. Plant uptake and removal of prometryn from the media were monitored for a period of 67 days. The results showed that the removal of the prometryn in the media was expedited by vetiver grass. The removal half-life (t1/2) was shortened by 11.5 days. Prometryn removal followed first-order kinetics (Ct = 1.8070e(-0.0601t)). This study demonstrated the potential of vetiver grass for the phytoremediation for prometryn.

Abstract
The blue fox (Alopex lagopus), a coat-color variant of the Arctic fox, is a domesticated fur-bearing mammal. In the present study, transcriptome data generated from a pool of nine different tissues were obtained with Illumina HiSeq2500 paired-end sequencing technology. After filtering from raw reads, 32,358,290 clean reads were assembled into 161,269 transcripts and 97,252 unigenes by the Trinity fragment assembly software. Of the assembled unigenes, 37,967 were annotated in the National Center for Biotechnology Information (NCBI) Non-Redundant (NR) protein database and 26,264 in the Swiss-Prot database. Among the annotated unigenes, 24,839 and 24,267 were assigned using the Gene Ontology (GO) and euKaryotic Orthologous Groups (KOG) databases, respectively. Altogether, 17,057 unigenes were mapped onto 227 pathways using the Kyoto Encyclopedia of Genes and Genomes database. In addition, 6394 simple sequence repeats were identified by examining 12,965 unigenes (>1 kb), which could contribute to the development of molecular markers. This study generated transcriptome data for the blue fox that will promote further progress in expression profiling studies, and provide a good annotation basis for genomic studies.

Abstract
B chromosomes are dispensable and co-exist with autosomal and sex chromosomes. The karyotype of the Chinese raccoon dog (Nyctereutes procyonoides procyonoides) comprises 0-4 B chromosomes. The proto-oncogene KIT is found on all B chromosomes of the Chinese raccoon dog. In the present study, partial DNA and mRNA sequences of KIT were amplified and sequenced from four individuals containing B chromosomes. Sequence analyses revealed that polymorphisms including single nucleotide polymorphisms (SNPs) and inserts/deletions were rich in the KIT gene of Chinese raccoon dog at the genomic level. However, no polymorphism was detected at the mRNA level. A comparison of mRNA sequences from Chinese raccoon dogs with the corresponding sequences derived from arctic fox and dog, which do not contain B chromosomes, revealed the mRNA sequences of the 10 SNPs to be identical between these three species. Therefore, these findings suggest that KIT located on the B chromosomes in Chinese raccoon dog lacks transcriptional activity.

Abstract
The cDNAs of two C-type lectins in grass carp Ctenopharyngodon idella, galactose-binding lectin (galbl) and mannose-binding lectin (mbl), were cloned and analysed in this study. Both of them exhibited the highest expression level in liver, whereas their expression pattern differed in early phase of embryonic development. Following exposure to grass carp reovirus (GCRV), the mRNA expression level of galbl and mbl was significantly up-regulated in liver and intestine.

Abstract
Amelogenin is a major protein of the developing enamel matrix. There are two amelogenin genes (AMELX and AMELY) located on the X and Y chromosomes, respectively, in dogs. In the present study, we characterized full-length cDNAs and alternative splicing patterns of the AMEL genes in the tooth tissue of a dog by 5'- and 3'-rapid amplification of cDNA ends and AMEL-specific RT-PCR. Sequence analysis revealed that the coding regions of AMELX and AMELY were 579 and 576 bp (accession Nos. KP244310 and KP244311), respectively. The coding sequence of AMELX had 95.1% identity to that of AMELY. The AMEL genes on X and Y chromosomes were both expressed in developing tooth tissue. Eight different alternatively spliced transcripts were identified, five from AMELX and three from AMELY.

Abstract
The quantity, quality, and distribution of eumelanin and pheomelanin determine a wide variety of coat colors in animals. Three coat color variants exist in farmed wild-type Chinese raccoon dog (Nyctereutes procyonoides procyonoides), which is an important fur-bearing animal species. The ASIP gene is an important candidate gene for coat color variation in some species. In this study, the complete cDNA sequences of ASIP were amplified from a wild-type Chinese raccoon dog. Sequence analysis revealed the coding region of ASIP in Chinese raccoon dog to be 396-bp in length and two transcripts (accession Nos. KT224450 and KT224451) were identified due to the alternative use of exon 1 (1A and 1C). However, the alternative splicing pattern and the coding sequence of ASIP in three types of coat color variants were the same as those identified in the wild-type individual. Based on the results obtained in this study, we can exclude a role for alternative splicing of exon 1 and the coding sequence of ASIP in coat color variation in Chinese raccoon dog.

Abstract
Intensive selection of broilers for improved growth rate is known to exert a negative effect on broiler health, such as an increase in body fat (and its related diseases). Excessive fat deposition in the liver can cause fatty liver hemorrhagic syndrome (FLHS); in addition, traits associated with liver fat have also been associated with FLHS. This study explored the genetic relationships among liver fat-related traits. Data was collected from 462 birds derived from 16th generation Northeast Agricultural University broiler lines divergently selected for abdominal fat content. The body weight at 7 weeks of age (BW7), abdominal fat weight (AFW), abdominal fat percentage, liver fat percentage (LFP), liver weight, and liver percentage were measured. The heritability of these traits and the phenotypic and genetic correlations were estimated, using the restricted maximum likelihood (REML) and Gibbs sampling (GS) methods. The REML and GS methods yielded similar heritability estimates for LFP (0.36 and 0.37, respectively). BW7 showed a high positive genetic correlation with AFW (rA(REML) = 0.74 and rA(GS) = 0.80), and a moderate positive genetic correlation with LFP (rA(REML) = 0.27 and rA(GS) = 0.39). Positive genetic correlations were also observed between AFW and LFP (rA(REML) = 0.35 and rA(GS) = 0.36). These results suggested that selection for growth may increase the AFW and LFP in broilers. LFP is directly related to FLHS; therefore, selection for broiler growth rate may increase the incidence of FLHS.

Abstract
The Chinese raccoon dog (Nyctereutes procyonoides procyonoides) is one of the most important fur-bearing animal species. The dominant white individual, a coat color variant in farmed Chinese raccoon dog, shows a completely white phenotype over the entire body. The KIT and EDNRB genes have been reported to be associated with the dominant white coat color in some mammalian species. In the present study, the full-length coding sequences of KIT and EDNRB were amplified from a dominant white and a wild-type Chinese raccoon dog. Sequence analysis revealed that the coding region of KIT and EDNRB in Chinese raccoon dog was 2919 and 1332 base pairs in length (accession No. KM083121 and KM083122), respectively, and 2 single-nucleotide polymorphisms (SNPs; c.600C>T and c.967G>A) in KIT and 1 SNP (c.259A>C) in EDNRB was found only in the dominant white individual. An alternative splicing site at the boundary of 4 and 5 of the KIT gene was identified in both individuals. We further investigated the association between the 3 SNPs of KIT and EDNRB and dominant white coat color by genotyping 18 individuals. We found no association between these SNPs and dominant white coat color. Based on these results, we can exclude the coding regions of the KIT and EDNRB genes as determinants of the dominant white coat color in Chinese raccoon dog.

Abstract
Dental caries remains one of the most common infectious diseases of humankind, which develops slowly throughout life, affecting children, adolescents, and adults. A vaccine against caries is urgently needed. We previously developed recombinant flagellin as a mucosal adjuvant for anti-Streptococcus mutans vaccines by nasal immunization. Furthermore, we demonstrated a fusion protein strategy that combined flagellin and the target surface adhesion protein (PAc) in a single construct. This construct enhanced specific IgA responses in oral fluids and provided improved prophylactic protection against caries. In the present study, we observed prolonged progression of dental caries in rats after S. mutans Ingbritt challenge. In addition, we observed a therapeutic effect of the flagellin-PAc fusion protein (KF-rPAc) against dental caries as a mucosal vaccine with a new immunization protocol. The present study demonstrated that KF-rPAc by nasal immunization can promote PAc-specific systemic and mucosal antibody responses and inhibit dental caries progression efficiently after the implant of S. mutans into the oral cavity of the rats. The rats immunized with KF-rPAc exhibited 53.9% caries reduction compared with the sham-immunized rats. Our data support the concept of administration of KF-rPAc to humans after infection and even caries that has begun to alleviate caries progression. In conclusion, our study demonstrated that KF-rPAc could be used as an anticaries therapeutic mucosal vaccine.
