Abstract
Heterocyclic Quaternary Phosphonium Salts (HQPS) have emerged as promising chemicals for organic synthesis and medicinal chemistry. However, the present synthetic methodology of this type of compound is still limited. Here, we report a deconstructive reorganization strategy based on Brønsted acid-mediated tandem 1,4 addition/intramolecular cyclization of triphenylphosphine derivatives and in situ generated o-AQMs for the first time. This protocol provides a novel approach to heterocyclic quaternary phosphonium salts. The method also features a non-metal catalyst, mild reaction conditions, high efficiency and wide substrate scope. Moreover, a series of obtained heterocyclic phosphonium salts can be converted to isotopically labelled 2-benzofuran compounds directly by simple deuteration reactions.

Abstract
Liver cancer belongs to Gastrointestinal (GI) malignancies which is a common clinical disease, a thorny public health problem, and one of the major diseases that endanger human health. Molecules from natural products (NPs) or their derivatives play an increasingly important role in various chronic diseases such as GI cancers. The chemical composition of the Alstonia yunnanensis Diels roots was studied using silica column chromatography, gel chromatography, recrystallization, and HPLC, and the compounds were structurally identified by modern spectral analysis using mass spectrometry (MS) and nuclear magnetic resonance (1H-, 13C-, HMQC-, HMBC-, and 1H-1HCOSY-NMR), ultraviolet and visible spectrum (UV), and electronic Circular Dichroism (ECD). Acetoxytabernosine (AC), an indole alkaloid with antitumor activity, was isolated from Alstonia yunnanensis Diels root. The current study aimed to investigate the influence of AC on the cell proliferation of BEL-7402 and SMMC7721 and to elucidate the underlying mechanism. The absolute configuration of AC was calculated by ECD (electronic circular dichroism). The effects of AC on the viability of different tumor cell lines were studied by the SRB method. The death mode of human hepatoma cells caused by AC was studied by TUNEL cell apoptosis detection and AnnexinV-FITC/PI double staining image. Mitochondrial membrane potential was detected by JC-1. The effects of AC on the expression of apoptosis-related proteins (Caspase9, Caspase3, and Parp-1) in SMMC7721 and BEL-7402 cells were detected by western blot. It was found that the absolute configuration of AC is 19(s), 20(s)-Acetoxytabernosine. AC could induce apoptosis of SMMC7721 and BEL-7402, and block the replication of DNA in the G1 phase. Under the treatment of AC, the total protein expression of apoptosis-related proteins (Caspase9, Caspase3, and Parp-1) significantly decreased in SMMC7721 and BEL-7402. The results suggested that AC induced apoptosis through a caspase-dependent intrinsic pathway in SMMC7721 and BEL-7402, and natural product-based drug development is an important direction in antitumor drug discovery and research.

Abstract
Objective: To establish and validate a nomogram model for predicting the risk of microvascular invasion(MVI) in hepatocellular carcinoma. Methods: The clinical data of 210 patients with hepatocellular carcinoma who underwent hepatectomy at Department of Hepatobiliary and Pancreatic Surgery,the Affiliated Hospital of Qingdao University from January 2013 to October 2021 were retrospectively analyzed. There were 169 males and 41 females, aged(M(IQR)) 57(12)years(range:30 to 80 years). The patients were divided into model group(the first 170 cases) and validation group(the last 40 cases) according to visit time. Based on the clinical data of the model group,rank-sum test and multivariate Logistic regression analysis were used to screen out the independent related factors of MVI. R software was used to establish a nomogram model to predict the preoperative MVI risk of hepatocellular carcinoma,and the validation group data were used for external validation. Results: Based on the modeling group data,the receiver operating characteristic curve was used to determine that cut-off value of DeRitis ratio,γ-glutamyltransferase(GGT) concentration,the inverse number of activated peripheral blood T cell ratio (-aPBTLR) and the maximum tumor diameter for predicting MVI, which was 0.95((area under curve, AUC)=0.634, 95%CI: 0.549 to 0.719), 38.2 U/L(AUC=0.604, 95%CI: 0.518 to 0.689),-6.05%(AUC=0.660, 95%CI: 0.578 to 0.742),4 cm(AUC=0.618, 95%CI: 0.533 to 0.703), respectively. Univariate and multivariate Logistic regression analysis showed that DeRitis≥0.95,GGT concentration ≥38.2 U/L,-aPBTLR>-6.05% and the maximum tumor diameter ≥4 cm were independent related factors for MVI in hepatocellular carcinoma patients(all P<0.05). The nomogram prediction model based on the above four factors established by R software has good prediction efficiency. The C-index was 0.758 and 0.751 in the model group and the validation group,respectively. Decision curve analysis and clinical impact curve showed that the nomogram model had good clinical benefits. Conclusions: DeRitis ratio,serum GGT concentration,-aPBTLR and the maximum tumor diameter are valuable factors for preoperative prediction of hepatocellular carcinoma with MVI. A relatively reliable nomogram prediction model could be established on them.

Abstract
Diabetic retinopathy (DR), one of the chronic complications of diabetes, is a serious and irreversible blinding disease. It is difficult to detect in the early stage, to control in the progressive stage, to operate in the advanced stage of DR. Recently, the "14th Five-year plan" for National Eye Health proposed to "improve the management mode of chronic eye disease, and build a chronic disease management system". The project team used artificial intelligence technology based on cloud platform, joint outpatient service, virtual ward to explore the comprehensive management of DR from the aspects of early screening, multidisciplinary collaborative diagnosis and treatment, and refined blood glucose management during perioperative period. In the future, it is urgent to integrate DR chronic disease management with other systemic chronic diseases to reduce the blindness caused by DR.

Abstract
Objective: To explore the role of parental reproductive age on the risk of overweight and obesity in offspring. Methods: The participants were derived from physical examination data of students aged 6-18 years in seven provinces in China, and questionnaire survey was used to collect demographic characteristics and lifestyle information of the students and their parents. A total of 41 567 children with complete data were included. According to the restricted cubic spline curve, maternal reproductive age was divided into three categories, 14-23, 24-28, and 29-38 years, and paternal reproductive age was divided into 14-23, 24-30, and 31-42 years. Multivariate logistic regression model was used to analyze the association between parental reproductive age and parental nutritional status and the risk of overweight and obesity in offspring. Results: The mean age of 41 567 children was (10.6±3.2) years, and the mean paternal and maternal age were (27.9±4.4) years and (25.8±4.0) years, respectively. The detection rate of overweight and obesity was 23.4%. After adjusting factors of children diet and behaviors, the OR(95%CI)of offspring overweight and obesity in groups of fathers aged 24-30 years and mothers aged 24-28 years was 1.11 (1.04-1.18) and 1.16 (1.08-1.24), respectively. When none parents were overweight and obese, the difference of obesity risk was not statistically significant. When both parents were overweight and obese, the OR(95%CI)of offspring overweight and obesity in groups of fathers aged 24-30 years and mothers aged 14-28 years old was 1.27 (1.00-1.62) and 1.33 (1.07-1.65) respectively. Conclusion: Parental reproductive age and parental overweight and obesity status may both increase the risk of overweight and obesity in offspring, with a significant interaction effect.

Abstract
In this paper, an active fault-tolerant tracking control scheme for the turbofan engine under dynamic and simultaneous actuator faults and sensor faults under disturbances is proposed. First, based on the linear parameter-varying model of the turbofan engine, an H∞ state feedback nominal controller is designed so as to achieve rotor speed tracking control with adaptive gain scheduling characteristics at different working conditions for the turbofan engine. Next, for the control system with simultaneous multiplicative actuator faults and additive sensor faults, a virtual actuator based active fault-tolerant tracking control strategy is developed to reconfigure the system such that it can obtain the similar behavior to the fault-free system without modifying the nominal controller. Specifically, in addition to handle the actuator fault by the virtual actuator, the reconfigured controller adopts a feedforward control signal to compensate for the sensor fault. Besides, in order to guarantee the reconfigured system, a sufficiency criterion is proposed. Finally, simulations have been conducted on a twin-spool turbofan engine to verify the effectiveness of the strategy.

Abstract
AbstractHerein, we present a palladium-catalyzed tandem [4+1] cycloaddition of 4-vinyl-1,4-dihydro-2H-3,1-benzoxazin-2-ones with N-tosylhydrazones. The reaction is accomplished by merging the in situ generated aza-ortho-quinone methides (aza-o-QMs) with nucleophilic carbenes. This method enables the construction of diverse indolines with broad functional group compatibility in good yields with high levels of diastereoselectivity under mild conditions.

Abstract
The necrotrophic pathogen Sclerotinia sclerotiorum is one of the most damaging and economically important plant pathogens. Pydiflumetofen, which was developed by Syngenta Crop Protection, has already been registered in China for the management of Sclerotinia stem rot, which was caused by S. sclerotiorum in oilseed rape. In an attempt to preempt and forestall the development of resistance to this useful fungicide, the current study was initiated to investigate the potential mechanism of resistance in laboratory mutants. Five pydiflumetofen-resistant S. sclerotiorum mutants were successfully generated by repeated exposure to the fungicide under laboratory conditions. Although the mutants had greatly reduced sensitivity to pydiflumetofen, they were also found to have significantly (P < 0.05) reduced fitness, exhibiting reduced mycelial growth and sclerotia formation on potato dextrose agar medium. However, three of the four mutants had significantly (P < 0.05) increased pathogenicity on detached soybean leaves compared with their respective parental isolates, indicating a moderate to high level of fungicide resistance risk according to the criteria of the Fungicide Resistance Action Committee. Sequence analysis of four succinate dehydrogenase (Sdh) target genes identified several nucleotide changes in the sequences of the pydiflumetofen-resistant mutants, most of which were synonymous and caused no changes to the predicted amino acid sequences. However, all of the pydiflumetofen-resistant mutants had two amino acid point mutations (A11V and V162A) in their predicted SsSdhB sequence. No similar changes were found in the SsSdhA, SsSdhC, and SsSdhD genes of any of the mutants tested. In addition, there was a positive cross-resistance between pydiflumetofen and boscalid, and no cross-resistance between pydiflumetofen and other commonly used fungicides, including tebuconazole, fludioxonil, cyprodinil, dimethachlone, prochloraz, pyraclostrobin, fluazinam, procymidone, and carbendazim. These results indicate that pydiflumetofen has great potential as an alternative fungicide for the control of S. sclerotiorum, especially where resistance to other fungicides has already emerged. Mixing or alternate application with fludioxonil, prochloraz, and fluazinam could be used to limit the risk of resistance to pydiflumetofen.

Abstract
Experiments were conducted to determine how exogenous abscisic acid (ABA) mediates the tolerance of plants to cadmium (Cd) exposure. Cd stress strongly reduced all the growth parameters of mung bean seedlings. Cd significantly increased ascorbate peroxidase (APX) and catalase (CAT) activities in roots and stems, and peroxidase (POD) activities in roots, stems, and leaves of mung bean seedlings. Cd caused remarkable increases in the levels of leaf chlorophyll and carotenoid, root polyphenols, and malondialdehyde (MDA) and proline in the three organs. However, Cd greatly decreased leaf CAT activity, root and leaf ascorbic acid (AsA) levels, and stem and leaf polyphenol levels. Foliar application of ABA partially alleviated Cd toxicity on the seedlings. ABA could restore most of the changed biochemical parameters caused by Cd, suggesting that ABA played roles in the protection of membrane lipid peroxidation and the modulation of antioxidative defense systems in response to Cd stress. Our results also implied the differential physiological and biochemical responsive patterns of roots, stems, and leaves to Cd and ABA in mung bean seedlings. The great changes in many biochemical parameters in roots suggested that roots were the first to be affected by Cd and play pivotal roles in response to Cd, especially in chelating Cd and reducing Cd absorption.

Abstract
Objective: To explore the value of neuroendoscopy combined with fluorescence angiography in anterior circulation aneurysm clipping. Methods: A total of 15 patients with anterior circulation aneurysm from Department of Neurosurgery, Zhongnan Hospital of Wuhan University between October 2018 and January 2019 were enrolled. Neuroendoscopy combined with indocyanine green fluorescence angiography (ICGA) was used to determine the shape of the aneurysm, the specific location of the aneurysm neck and its relationship with the aneurysm-bearing artery during anterior circulation aneurysm clipping. Meanwhile, Neuroendoscopy combined with ICGA can be employed to observe whether there was stenosis and incomplete clamping of the aneurysm-bearing artery after clipping the aneurysm, and whether there was misclamping of the perforating branches hidden under the posterior wall of the aneurysm. Results: The success rate of aneurysm clipping in 15 cases was 15/15. After aneurysm clipping, ICGA and neuroendoscopy were performed. The residual aneurysm neck was detected in 3 cases, and the position of aneurysm clip was adjusted or aneurysm clips were added. In one case, the anterior choroidal aneurysm was found to be mistakenly clipped. After adjusting the aneurysm clip, ICGA and neuroendoscopy showed that the anterior choroidal artery was normal. In another case, the A1 segment aneurysm was clipped. ICGA and neuroendoscopy found that the perforating branch blood vessels were mistakenly clipped. After the adjustment of the aneurysm clip, the blood vessels recovered their patency. There were no surgical-related deaths, disability and coma cases in the study. Conclusions: During aneurysm clipping, neuroendoscopy combined with ICGA can reduce cerebral vasospasm, decrease the misclipping rate of perforation of blood vessels, and avoid residual neck of aneurysm, stenosis or occlusion of aneurysm-bearing artery by using neuroendoscopy to observe whether misclipping of the perforating branch vessels exist and whether the aneurysm is clipped. Therefore, it can reduce postoperative complications.

Abstract
Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of gastrointestinal glomus tumors (GIGT). Methods: Totally 15 cases of GIGT were collected at the First Affiliated Hospital, Zhengzhou University, from January 2011 to June 2018. The clinicopathological features, immunophenotype, BRAF V600E mutation and prognosis were retrospectively analyzed. Results: The 15 patients' age ranged from 37 to 59 years(median 49 years, mean 50 years). Eleven patients presented with intermittent abdominal pain and distention, three showed antral space-occupying lesions at physical examination, and one had abdominal pain accompanied by fecal blood. Fourteen tumors were located in the stomach, and one was in the ileum. Imaging showed the gastric glomus tumors were located in the submucosal layer with obvious enhancement in the arterial phase, and the ileum glomus tumor involved the whole layer of intestinal wall causing luminal obstruction. The maximum diameters of the tumors ranged from 1.5 to 3.0 cm (mean 2.3 cm). Grossly, the gastric glomus tumors were solid. Microscopically, the gastric glomus tumors were mostly located in the muscularispropria layer and were vascular. The tumor boundary was distinct but without capsule formation. The tumor cells were round or oval, and showed perivascular hemangiopericytoma-like or solid nest-like structures. The tumor cells were mildly pleomorphic, with rare mitosis and no necrosis. Two tumors had focal calcification, two showed mucosal invasion, two showed vascular invasion and five showed perineural invasion. The ileum glomus tumor was cellular, with prominent cellular atypia, and the mitotic count in hot spots was about 5-6/HPF. Immunohistochemistry showed that SMA and collage Ⅳ were strongly expressed in all the tumor cells; caldesmon and calponin were moderately expressed in some regions, and syn was weakly expressed in 12 cases. The Ki-67 proliferation index in the gastric glomus tumors ranged from 1% to 30% (mean 6%); and that in the ileum glomus tumor was about 70%. BRAF V600E mutations were not detected in any of 15 GIGTs. All patients did not receive radiotherapy or chemotherapy post operatively. Thirteen patients were followed up by telephone for 18-90 months (mean 42 months). Twelve patients with gastric glomus tumors survived without recurrence and metastasis, and the patient with ileum glomus tumor had liver metastasis 15 months after operation. Conclusions: Glomus tumors is a rare mesenchymal tumor of the gastrointestinal tract. It should be differentiated from gastrointestinal stromal tumors, neuroendocrine tumor, leiomyoma, solitary fibrous tumor and paraganglioma. Most GIGTs are benign and have good prognosis. More experience is needed to understand the biologic behavior and prognostication of GIGTs.

Abstract
Objective: To investigate the clinicopathological features and prognosis of patients with neuroendocrine tumors (NETs). Methods: The clinicopathologic data of enrolled patients with NETs between October 2012 and October 2017 at the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Results: Among the 488 NETs patients, the average age was (51.0±15.8) years, and the sex ratio (male/female) was 1∶1.1. Of the NETs, 370 were located in the digestive system (75.8%), 63 were pulmonary (12.9%), 14 were mediastinal (2.9%), 7 were of unknown primary origin (1.4%), and 34 were located in other sites (7.0%). Among the NETs, the pancreas, rectum and stomach were the most common sites. In the digestive system NETs, the most common tumor grade was G1 (190 cases, 51.4%), followed by G2 (143 cases, 38.6%) and NET-G3 (37 cases, 10.0%). In pulmonary NETs, typical and atypical carcinoid tumors was 47.6% and 52.4%, respectively. There were 310 patients at stage Ⅰ/Ⅱ, 53 at stage Ⅲ, 69 at stage Ⅳ and 56 at stage undiagnosed, respectively. The relationships among age, stage, grade, metastasis, treatment and prognosis were analyzed. All these factors could influence the survival rate of NET patients. Multivariate Cox analysis showed that age (>50 years old) (HR=2.831, 95%CI:1.414-7.029, P=0.025) and distant metastasis (HR=10.208, 95%CI:4.110-25.355, P<0.001) were independent risk factors. Conclusions: The most common primary sites of NETs are the pancreas, rectum, and stomach. Age and distant metastasis are independent risk factors for the prognosis of NETs.

Abstract
Systematic measurements of electrical resistivity and Hall coefficient under high pressure were performed on CaFe0.88Co0.12AsF single crystal samples. The superconductivity is suppressed quickly by pressure and can not be detected down to 2 K at above 12.7 GPa, while the magnitude of the Hall coefficient [Formula: see text] shows a very weak pressure and temperature dependence. A comprehensive analysis considering the pressure dependence of [Formula: see text], [Formula: see text], residual resistivity ratio, and the Fermi-liquid term of the resistivity indicates that the electron correlation is an important factor in superconductivity of iron-based superconductors.

Abstract
The Dongyuan groundwater source area, which is the main drinking water source of Ji'nan City, is karst fissure water. To identify groundwater recharge sources, the influence of surface water, hydrochemical evolution, hydrochemical and isotopic components (2H and 18O) of groundwater and surface water samples collected from the Dongyuan groundwater source were investigated.The results showed that the hydrochemical characteristics of groundwater were similar, and the main ions were Ca2+, HCO3-, and SO42-. The groundwater, which suffered evaporation to varying degrees, was recharged mainly by precipitation. The hydrochemical composition of regional groundwater is mainly controlled by water-rock interactions, including dissolution/precipitation of carbonate minerals in the limestone aquifers and hydrolysis of silicates minerals in the quaternary aquifers, above the limestone aquifers. In some areas, groundwater was polluted by infiltration of river water. The main indicators of groundwater pollution that exceeded groundwater quality standards were total hardness, NO3-, NH4+, SO42-, Fe, and Mn.

Abstract
Objective: To analyze the completion status, monitoring results, and existing problems of key occupational disease monitoring in Shandong, China, from 2015 to 2017, and to provide reference materials for improving monitoring quality and carrying out occupational disease prevention and control. Methods: The monitoring situation including project coverage, data collection, monitoring results, and monitoring quality of key occupational diseases in Shandong from 2015 to 2017 were described and comparatively analyzed. Results: In the past three years, the uncoverage rate of monitored counties (38.69% in 2015, 10.95% in 2016, and 5.11% in 2017) , the non-work rate of occupational health examination institutions (41.67% in 2015, 18.02% in 2016, and 8.72% in 2017) , and the non-work rate of occupational disease diagnosis institutions (42.31% in 2015, 38.46% in 2016, and 38.46% in 2017) in Shandong decreased year by year. The number of institutions with key occupational hazard factors reported to the safety supervision and management department increased year by year (it was 24140 in 2017, with an increase of 40.50% compared with 2016 and an increase of 114.62% compared with 2015) ; the key occupational hazard factors in enterprises were mainly noise (72.76%) , followed by benzene, silica dust, and coal dust. The number of workers exposed to key occupational hazard factors reported to the safety supervision and management department increased year by year; in 2017, it was 729245, with an increase of 39.78% compared with 2016 and an increase of 84.81% compared with 2015. The ratio of people exposed to key occupational hazard factors identified by the medical examination to the total people in the safety supervision system in a year decreased year by year (40.87% in 2015, 23.86% in 2016, and 17.95% in 2017) . Conclusion: In Shandong, the supervision of enterprises with key occupational hazard factors and the responsibility of enterprise protection should be strengthened. The occupational health examination rate of workers should be improved. It is suggested that we should carry out the special investigations and occupational health risk assessment for key enterprises and key populations.

Abstract
Objective: To investigate the clinicopathological features of gangliocytic paraganglioma(GP). Methods: Clinical data and pathological diagnosis of the 4 cases of GP were obtained through the medical record inquiry from January 2011 to December 2017 at the First Affiliated Hospital of Zhengzhou University. Routine HE staining and immunohistochemistry of CKpan, Syn, CgA, CD56, NSE and NF were performed. Clinical follow-up of the patients was obtained through telephone communication. Results: All 4 patients, including 2 male and 2 female patients, presented with intermittent abdominal pain and distention. The median age was 56 years. Preoperative CT showed local thickening of the duodenum wall with slight enhancement in all four cases. Endoscopic ultrasonography showed low level echo in the mucous layer and submucosa involved by the tumor in 3 of 4 cases. The maximal diameter of the tumor ranged from 0.6 to 1.8 cm with an average of 1.2 cm. Microscopically, the tumors consisted of epithelioid, spindle and ganglion-like cells, and the proportion of the three cell types was different among cases. Epithelioid cells expressed CKpan, Syn, CgA and CD56. Spindle cells expressed S-100 protein and SOX-10 and ganglion-like cells expressed NF, Syn, CgA and CD56.All tumour cells expressed NSE. All 4 patients had no recurrence a post-surgery follow-up period of 3 to 30 months. Conclusions: GP of the duodenum is a benign tumor with excellent prognosis after endoscopic excision. Although its incidence is very low, its diagnosis should be considered for any mass lesion of the duodenum, especially involving mucosa and submucosa of the second dudenal segment.

Abstract
Objective: To evaluate the expression of cytokeratin (CK)7, CK8/18, CK19 and p40 in esophageal squamous cell carcinoma (ESCC) and its significances. Methods: One hundred and ninety cases of surgically resected ESCCs and 154 normal esophageal tissues as control were collected at the First Affiliated Hospital of Zhengzhou University in 2012.Of the 190 ESCC cases including 116 male and 74 female, aged 28-82 (60.3±8.6) years, 88 cases <60 years old and 102 cases ≥60 years old. Tissue sections were immunostained for CK7, CK8/18, CK19 and p40, and the expression was evaluated and correlated with the clinicopathologic findings and outcome. Results: CK19 and p40 were expressed in 190 cases of ESCCs; with 147 cases (77.4%) and 151 cases (79.5%) showing high p40 and CK19 expression, respectively; while 43 cases (22.6%) and 39 cases (20.5%) showed low p40 and CK19 expression, respectively. The low expression groups showed more lymph node metastases and higher pTNM stages compared to the high expression groups. The high CK19 expression group showed better prognosis than the low expression group (P<0.01); p40 expression was not correlated with prognosis(P>0.05). In contrast, CK7 and CK8/18 expression was only seen in 29 cases (15.3%) and 59 cases (31.1%) of ESCCs, respectively, and their expression correlated significantly with the degree of tumor differentiation and lymph node metastasis (P<0.05). The prognosis in the CK7 negative group was better than that in the CK7 positive group. Similar results were found in CK8/18 expression. Multivariate analysis revealed that pTNM stages, low CK19 expression and CK8/18 expression were independent prognostic factors. Conclusions: Low p40 expression and the expression of CK7 and CK8/18 cannot exclude poorly-differentiated ESCCs.CK7 and CK8/18 expression and low CK19 and p40 expression in the ESCCs are associated with lymph node metastasis and poor prognosis. Decreased expression of CK19 and positive expression of CK8/18 in ESCCs are independent prognostic markers.

Abstract
Emerging and legacy hydrophobic pollutants, including halogenated flame retardants (HFRs), organophosphorus FRs (OPFRs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs), as well as polycyclic aromatic hydrocarbons (PAHs) were determined in coastal sediments of Hainan Island, southern China, where little information is known about their contamination. The HFRs were dominated by decabrominated diphenyl ethers (median = 1.32 ng/g) and novel decabromodiphenyl ethane (1.87 ng/g). HFR and PAH concentrations had similar spatial distributions, with higher levels in the river and near the estuary. The concentrations of ∑10OPFRs ranged from 0.74 to 60.0 ng/g (median = 15.3 ng/g), displaying a different spatial distribution. ∑DDTs and β-HCH, with median concentrations of 1.41 and 3.44 ng/g respectively, were largely from historical inputs, but use of DDT still exists in Hainan. Principal component analysis revealed the associations between most of the pollutants (HFRs, OCPs, and PAHs) and perylene, indicating that terrestrial runoff plays a significant role in their presence in the coastal sediments. OPFRs had different emission sources or entry modes to the coastal ocean.

Abstract
Objective: The purpose of this study was to assess the efficacy of ultrasound-guided continuous fascia iliaca compartment block combined with oral analgesics for pre-operative pain control in elderly patients with hip fracture. Methods: One hundred and sixteen patients with hip fractures in Xuan Wu Hospital of Capital Medical University during Dec. 2015 to Dec. 2016 were included. These patients were randomized into 2 groups: control group (group C) (receiving the traditional analgesia: tramadol 50 mg and paracetamol 500 mg tid, po from admission to surgery), study group (group S) (receiving ultrasound-guided continuous fascia iliaca compartment block combined with oral analgesics for pre-operative pain control from admission to surgery). Pain relief or pain intensity was assessed preoperatively at before administration of analgesia (T0), 1 h after administration of analgesia (T1), the second day after admission(T2), in the morning of surgery day (before surgery) (T3) using a visual analog scale. The satisfaction score with the analgesic regimen preoperatively was recorded. The amount of rescue analgesia, occurrence of adverse events (nausea, vomiting, respiratory depression, over sedation) and continuous fascia iliaca compartment block complications were also collected. Results: Pain scores (VAS) at passive movement of group S were significantly lower at T1 (32±8), T2 (32±8) and T3 (34±7) than that at T0 (73±12) (all P<0.05). VAS at rest of group S were significantly lower than those of group C at T3 (t=3.488, P<0.05). VAS at passive movement of group S were significantly lower than those of group C at T1,T2,T3 (P<0.05). The satisfaction score with the analgesic regimen was greater in group S (74±10) than that in group C (46±11) (t=-14.209, P<0.05). The incidence of rescue analgesia was lower in group S (0) than in group C (17.2%) (χ2=5.472, P<0.05). The occurrence of nausea and vomiting was 6.9% and 1.7% in group S, which were lower than that in group C (22.4%, 12.1%) (χ2=6.779, 2.416, all P<0.05). There were no obvious complications of continuous fascia iliaca compartment block in group S. Conclusion: Ultrasound guided continuous fascia iliaca compartment block combined with oral analgesics preoperatively is an effective way of providing analgesia for elderly with hip fracture, which can improve the patient's comfort and satisfaction.

Abstract
1. Over the past decade, rapid advancement in isolation methods for identifying markers of the once elusive intestinal stem cell (ISC) populations has laid the foundation for unravelling their complex interrelationships during homeostasis. Study on ISC in avian intestinal tissue might play a pivotal foundation for further studies on the epithelial-to-mesenchymal transition (EMT) in gastrointestinal disease and cell-based therapy as well as intestinal tissue engineering. 2. The following experiment isolated a population of fibroblast-like, plastic adhering cells derived from chick embryo intestine, showing a strong self-renewing and proliferative ability, which was maintained in vitro up to passage 25. The findings included growth characteristics, detected expression of cell surface markers and characterised the capability of these cells to differentiate towards the osteogenic, adipogenic, and chondrogenic cell lineages. 3. RT-PCR analysis showed that these cells from chick embryos expressed mesenchymal stromal cell markers CD44, CD90 and VIMENTIN as well as ISC-specific genes LGR5, MI1, SMOC2, BMI1, and HOPX. Immunofluorescence and flow cytometry confirmed this biology characterisation further. 4. In conclusion, cells were isolated from the intestine of 18-day-old chicken embryos that exhibited the biological characteristics of mesenchymal stromal cells as well as markers of intestinal stem cells. Our findings may provide a novel insight for in vitro cell culture and characteristics of ISCs in avian species, which may also indicate a benefit for obtaining cell source for intestinal tissue engineering as well as cell-based investigation for gastrointestinal disease and treatment.

Abstract
OBJECTIVE To analyze the association between sleep duration and athletic performance, and provide scientific basis to improve the 50 m and endurance performance in children and adolescents. METHODS All the 119 462 subjects aged 9-15 years in both genders were sampled from 2014 National Physical Fitness and Health Surveillance by using stratified random cluster sampling method, to measure the height, weight, 50 meters and endurance performance and investigate sleep duration with questionnaire. Their body mass indexes (BMI) were calculated and the students' 50 m, endurance run scores and sleep durations were assessed. Binary Logistic regression was used to analyze the difference between the different sleep groups, and multifactor Logistic regression was used to analyze the relationship between the sleep condition and athletic performance. RESULTS The prevalence of insufficient sleep was 94.67% in the total subjects, the prevalence was higher among the girls (95.26%)than the boys (94.09%, χ2=80.99, P<0.001), and higher among the urban (95.41%) than the rural students(93.93%, χ2=128.48, P<0.001).The children with sufficient sleep had better performance in 50 m and endurance run scores( χ250 m=10.10, P50 m<0.01; χ2endurance run=21.76, P<0.001). Logistic regression analysis after controlling the gender, area, grade and BMI showed that children with adequate sleep showed better results(OR50 m=1.14, 95%CI50 m=1.05-1.23, P50 m<0.01; ORendurance run=1.21, 95%CIendurance run=1.11-1.31, Pendurance run<0.001). As for gender, the excellent rates of 50 m and endurance run scores in the boys with adequate sleep were higher (P<0.001), but there were no significant difference in 50 m and endurance run excellent rates in the girls of different sleep conditions. The excellent rates of 50 m and endurance run in the urban children and the endurance rate in the rural children and adolescents with adequate sleep were higher than those with insufficient sleep (P<0.01) while there were no significant difference in the 50 m excellent rates between the different sleep groups in rural areas. The 50 m and endurance run excellent rates of the children and adolescents with adequate sleep in each grade were higher than those of the children in the same grade with insufficient sleep (Pprimary students' endurance performance<0.001, and the rest P<0.05). Children and adolescents with normal BMI and overweight who slept well had better performance in 50 m (P<0.05). The endurance run excellent rate of children and adolescents with adequate sleep in each BMI group was higher than that in children and adolescents with insufficient sleep in the same BMI group (Pmalnutrition<0.01, Pnormal<0.01, Poverweight<0.05, Pobesity<0.05). The children and adolescents were divided into different groups according to the sleep duration,the one who slept less than 7 hours had lower 50 m excellent rate than the other groups with longer sleeping duration (P<0.01) and the rate in the ones who slept more than 9 hours was the highest (P<0.001).The endurance excellent rate in the children and adolescents who slept more than 9 hours was significantly higher than that in the other groups (P<0.001).There was no significant dose-response relationship in excellent rates and sleep durations. CONCLUSION The prevalence of insufficient sleep has increased, and the sleep condition in children and adolescents is severe. Children and adolescents with sufficient sleep have better athletic performance, so we should strengthen the prevention and control of the lack of sleep in children and adolescents.

Abstract
Objective: To evaluate the application of the central lymph node dissection (CLND) for papillary thyroid carcinoma (PTC) in cN0 T1/T2. Methods: Retrospective analysis of 532 cases with PTC in cN0 T1/T2 who underwent CLND between October 2014 and September 2016 in the Department of Thyroid Surgery, the First Affiliated Hospital of the Kunming Medical University. The incidence of central lymph node (CLN) metastasis and risk factors were analyzed. Results: CLN metastasis rates: 41.2% (42/102) in males vs 34.9% (150/430) in females, P=0.252; 33.9% (116/342) in single focal carcinoma vs 40.4% (74/183) in multifocal carcinoma, P=0.157; 44.0% (125/284) in patients with 45 years old or less vs 27.0% (67/248) in patients more than 45 years old, P=0.000; 30.3% (113/373) in microcarcinoma vs 50.9% (81/159) in non-microcarcinoma, P=0.000.In unilateral lesions, ipsilateral CLN metastasis was correlated with the tumor diameter (P=0.012), but not with the number of lesions (P=0.653). also contralateral CLN metastasis was correlated with the tumor diameter (P=0.000), but not with the number of lesions (P=0.815). For the left or right unilateral single focal lesion, the tumor diameter was not correlated with the metastasis of the posterior to right recurrent laryngeal nerve central lymph nodes (LN-prRLN-CLN) (P=0.652, P=0.088). But in bilateral multifocal carcinoma the tumor diameter was correlated with metastasis of LN-prRLN-CLN (P=0.039). Conclusions: Prophylactic CLND is reasonable for PTC in cN0 T1/T2. A bilateral CLND should be conducted for patients with bilateral multi-focus cancer and unilateral or bilateral non-microcarcinoma, especially in patients more than 45 years old. For unilateral single focal microcarcinoma on the right, the content of CLND should be from laryngeal nerve on right center to posterior branche; for unilateral single focal microcarcinoma on the left side, the left CLND should be conducted. An ipsilateral CLND can be considered in patients with unilateral multifocal microcarcinoma, and generally a routine dissection of the LN-prRLN-CLN is not required, however for bilateral non-microcarcinoma and the the non-microcarcinoma on the right side, the LN-prRLN-CLN dissection should be conducted.

Abstract
Diallyl disulfide (DADS) has been shown to have multi-targeted antitumor activities. We have previously discovered that it has a repressive effect on LIM kinase-1 (LIMK1) expression in gastric cancer MGC803 cells. This suggests that DADS may inhibit epithelial-mesenchymal transition (EMT) by downregulating LIMK1, resulting in the inhibition of invasion and growth in gastric cancer. In this study, we reveal that LIMK1 expression is correlated with tumor differentiation, invasion depth, clinical stage, lymph node metastasis, and poor prognosis. DADS downregulated the Rac1-Pak1/Rock1-LIMK1 pathway in MGC803 cells, as shown by decreased p-LIMK1 and p-cofilin1 levels, and suppressed cell migration and invasion. Knockdown and overexpression experiments performed in vitro demonstrated that downregulating LIMK1 with DADS resulted in restrained EMT that was coupled with decreased matrix metalloproteinase-9 (MMP-9) and increased tissue inhibitor of metalloproteinase-3 (TIMP-3) expression. In in vitro and in vivo experiments, the DADS-induced suppression of cell proliferation was enhanced and antagonized by the knockdown and overexpression of LIMK1, respectively. Similar results were observed for DADS-induced changes in the expression of vimentin, CD34, Ki-67, and E-cadherin in xenografted tumors. These results indicate that downregulation of LIMK1 by DADS could explain the inhibition of EMT, invasion and proliferation in gastric cancer cells.

Abstract
Karst groundwater is an important source of water supply for the industrial and agricultural proposes and drinking water in Zaozhuang City. In recent years, with the development of industrialization and increasing of domestic water consumption, the sulfate pollution of karst groundwater has become a serious problem. 36 samples of surface and different depth of groundwater were collected in southern Zaozhuang City in August, 2014. Based on the analysis of the hydrochemical composition and the isotopic characteristics of δD, δ18O-H2O, and δ34 S-SO42-, this paper analyzed the influence of hydrogeochemical evolution of groundwater and human input in the area, in order to identify the scope and ways of sulfate pollution. The results showed that the basic hydrochemical type was HCO3·SO4-Ca, formation of geochemical components mainly included the dissolution of carbonate and sulfate minerals, oxidation of pyrite and the influence of human activities. Moreover, the main recharge of groundwater in study area was the atmospheric precipitation. The hydraulic connection was closely linked between the surface water and different depth of groundwater. The variation range of groundwater δ34 S-SO42- values was from 0.2‰ to 9.3‰, and the relationship between the δ34 S-SO42- value and SO42- value of groundwater showed different sources of sulfate. The sources of sulfate in groundwater included the dissolution of gypsum, the oxidation of pyrite, the leaching of fertilizer and infiltration of domestic sewage and industrial wastewater. In addition to the original geological factors, wastewater infiltration of industrial and mining enterprises was the main reason for the increase of sulfate content in the groundwater.

Abstract
Out-of-plane angular dependent torque measurements were performed on CaFe0.88Co0.12AsF single crystals. Superconducting fluctuations, featured by magnetic field enhanced and exponential temperature dependent diamagnetism, are observed above the superconducting transition temperature T c, which is similar to that of cuprate superconductors, but less pronounced. In addition, the ratio of T c versus superfluid density follows well the Uemura line of high-T c cuprates, which suggests the exotic nature of the superconductivity in CaFe0.88Co0.12AsF.

Abstract
Out-of-plane angular dependent torque measurements were performed on CaFe0.88Co0.12AsF (Ca1 1 1 1) single crystals. In the normal state, the torque data shows [Formula: see text] angular dependence and H (2) magnetic field dependence, as a result of paramagnetism. In the mixed state, the torque signal is a combination of the vortex torque and paramagnetic torque, and the former allows the determination of the anisotropy parameter γ. At T = 11.5 K, γ (11.5 K ≃ 0.5 T c) = 19.1, which is similar to the result of SmFeAsO0.8F0.2, [Formula: see text] at [Formula: see text]. So the 11 1 1 is more anisotropic compared to 11 and 122 families of iron-based superconductors. This may suggest that the electronic coupling between layers in 1 1 1 1 is less effective than in 11 and 122 families.

Abstract
Desmoglein 4 (DSG4) has an important role in the development of wool traits in domestic animals. The full-length DSG4 gene, which contains 3918 bp, a complete open-reading-frame, and encodes a 1040-amino acid protein, was amplified from Liaoning cashmere goat. The sequence was compared with that of DSG4 from other animals and the results show that the DSG4 coding region is consistent with interspecies conservation. Thirteen single-nucleotide polymorphisms (SNPs) were identified in a highly variable region of DSG4, and one SNP (M-1, G>T) was significantly correlated with white and black coat color in goat. Haplotype distribution of the highly variable region of DSG4 was assessed in 179 individuals from seven goat breeds to investigate its association with coat color and its differentiation among populations. However, the lack of a signature result indicates DGS4 haplotypes related with the color of goat coat.

Abstract
Long non-coding RNA (lncRNA) maternally expressed 3 (MEG3) is expressed in endothelial cells and involved in angiogenesis and vascular function. It was proposed that MEG3 participates in the process of endothelial progenitor cells (EPCs) functions in metabolic syndrome (MetS). In this study, the circulating EPCs number and function were decreased in MetS subjects. The MEG3 expression was expressed at a lower level and microRNA-140-5p (miR-140-5p) was expressed at a higher level in circulating EPCs of subjects with MetS. Pioglitazone reversed the alterations of EPCs function and the expression levels of MEG3 and miR-140-5p in EPCs. In bone marrow-derived EPCs exposed to palmitate, down-regulation of miR-140-5p canceled the increase of MEG3 expression level induced by Pioglitazone. Overexpression of MEG3 resulted in the down-regulation of miR-140-5p. The luciferase reporter assay and RIP assay showed that MEG3 targeted miR-140-5p. In addition, the HDAC7 expression levels were regulated by miR-140-5p and MEG3. These findings demonstrated that Pioglitazone up-regulated MEG3 expression to protect EPCs via decreasing miR-140-5p expression and increasing HDAC7 expression in MetS, which may be a novel therapeutic target for preventing and treating MetS.

Abstract
The mechanism of alternative AUG usage in foot-and-mouth disease virus is not completely understood. Using simple computational approaches, we evaluated the contributions of overall codon bias, quantitative codon bias, and %GC of the region between the two alternative AUGs, Region-La, as well as the nucleotide bias of the sequence context flanking each AUG with respect to translation initiation efficiency. For all serotypes of this virus, we found that only a small component of the effect of RNA secondary structure on ribosome scanning was due to the low %GC of Region-La. In addition, we found that the nucleotide bias of the context from position -4 to +6 flanking the AUG(2nd) had a negative correlation with the overall codon bias, and that a strong purine bias existed in this AUG(2nd)context. However, the quantitative codon bias of Region-La was seen to be significantly lower than that of Region-Lb (the sequence following AUG(2nd)) in all serotypes except SAT 1-3. Taken together, our results suggest that the low codon bias of Region-La might impair the translation initiation efficiency at the AUG(1st) in all serotypes except SAT 1-3, and the specific AUG(2nd) context might be used as a strong signal to initiate translation from the AUG(2nd) in all serotypes.

Abstract
The aim of this research was to identify the dynamic diversity of Small Tail Han sheep in its main producing areas between different years, and provide a basis for a breeding and genetic resources conservation strategy. For this purpose, 15 microsatellites were genotyped for Small Tail Han Sheep sampled in 2014 from Heze, China, and a comparative analysis of these data with those from a previous study was undertaken using meta-analysis. The results reveal that inbreeding has caused a reduction in diversity of Small Tail Han Sheep from 2008 to 2014. Overall, our results are helpful in understanding the dynamic change in diversity, as well as providing information for a conservation strategy for this population.

Abstract
Liver fatty acid binding proteins (L-FABP) are a family of small, highly conserved, cytoplasmic proteins that bind to long-chain fatty acids and other hydrophobic ligands. In this study, a full-length enriched cDNA library was successfully constructed from Wuzhishan miniature pig, and then the L-FABP gene was cloned from this cDNA library and an expression vector (pEGFP-N3-L-FABP) was constructed in vitro. This vector was transfected into hepatocytes to test its function. The results of western blotting analysis demonstrated that the L-FABP gene from our full-length enriched cDNA library regulated downstream genes, including the peroxisome proliferator-activated receptor family in hepatocytes. This study provides a theoretical basis and experimental evidence for the application of L-FABP for the treatment of liver injury.

Abstract
DRA encodes the alpha chain of the DR heterodimer, is closely linked to DRB and is considered almost monomorphic in major histocompatibility complex region. In this study, we identified the exon 2 of DRA to evaluate the immunogenetic diversity of Chinese south indigenous goat. Two single nucleotide polymorphisms in an untranslated region and one synonymous substitution in coding region were identified. These data suggest that high immunodiversity in native Chinese population.

Abstract
Tumor necrosis factor-α is a cytokine with a wide range of effects on both lymphoid and non-lymphoid cells. In this study, we identified polymorphisms in major histocompatibility complex class III gene in the 4th exon and the 3' untranslated region of tumor necrosis factor-α to evaluate the immunogenetic diversity of Chinese south indigenous goat. Three single-nucleotide polymorphisms were identified and showed similar frequencies in different except MI loci. These data suggest that the high immunodiversity of the tumor necrosis factor-α region within these breeds can be used for strengthening variety improvement and promoting animal husbandry development in Chinese indigenous goats.

Abstract
Based on the imaging process of pushbroom hyperspectral imager, a correction method for optic crosstalk was developed. An area that has white calibration target was selected as reference data. The target pixels crosstalk quantity was gained using the subtraction between the two lines of reference data, and it was fitted to restrain noise. Using recursion method, crosstalk quantity of single pixel was calculated from the fitted function, and it could be used to correct the optical crosstalk of the whole data. Three PHI (pushbroom hyperspectral imager) data which have different ground scene were corrected. It was showed that optical crosstalk in corrected data is lightened obviously, and the data quality is improved effectively in both the spectral dimension and spatial dimension. The spectral changing caused by optical crosstalk is also corrected, and the bands with definition increased more than 50% accounts for 83% of the total bands. Optic crosstalk is obtained form hyperspectral data itself which is independent of other data source. It is proved that the correction method is valid, and it is applicable for different ground type. The correction method also provides a way to measure the optic crosstalk of hyperspectral imager in the lab.

Abstract
PURPOSE We conducted a meta-analysis aiming to evaluate the relationship between a common polymorphism (rs2511989 G>A) in the SERPING1 gene and the risk of age-related macular degeneration (AMD). METHODS The PubMed, CISCOM, CINAHL, Web of Science, Google Scholar, EBSCO, Cochrane Library, and CBM databases were searched for relevant articles published before November 1, 2013, without any language restrictions. A meta-analysis was conducted using STATA 12.0 software. We calculated a crude odds ratio (OR) with a 95% confidence interval (95% CI) to evaluate the relationships under five genetic models. RESULTS Seven case-control studies with a total of 7,159 patients with AMD and 5,797 healthy subjects met the inclusion criteria. The results of our meta-analysis showed that the SERPING1 rs2511989 polymorphism might be correlated with an increased risk of AMD (G allele versus A allele: OR = 1.09, 95% CI = 1.03-1.15, p = 0.020; GG + GA versus AA: OR = 1.14, 95% CI = 1.03-1.26, p = 0.014; GG versus GA+AA: OR = 1.10, 95% CI = 1.02-1.19, p = 0.012; GG versus AA: OR = 1.20, 95% CI = 1.07-1.34, p = 0.002; respectively). Results of subgroup analysis by ethnicity revealed positive correlations between the SERPING1 rs2511989 polymorphism and risk of AMD among Caucasians under five genetic models (all p<0.05), but not among Asians (all p>0.05). CONCLUSIONS The current meta-analysis shows that the SERPING1 rs2511989 polymorphism may have a positive effect on the risk of AMD, especially among Caucasians.

Abstract
In the present study, real time-polymerase chain reaction was applied to analyze the expression of IGF-I and MyoG genes in Hu sheep longissimus dorsi at different growth stages and their association with meat traits. Expression of the IGF-I gene in Hu sheep differed significantly between males and females at the two day-old (0.01 < P < 0.05), one-month old (0.01 < P < 0.05), and three month-old (P < 0.01) stages. IGF-I gene expression in male longissimus muscles was higher than that of females at all growth stages, except for the three month-old stage. There was no significant difference (P > 0.05) between males and females at any growth stage in expression of the MyoG gene. MyoG gene expression in male longissimus muscles tended to be higher than that of females at all growth stages, except for the six month-old stage. IGF-I gene expression was significantly and positively correlated with live weight (P < 0.01) and carcass weight (0.01< P < 0.05), and was non-significantly positively correlated with net meat weight (P > 0.05). In contrast, MyoG gene expression was non-significantly and positively correlated with live weight, carcass, and net meat weight (P > 0.05). Carcass traits showed highly significant positive correlations (P < 0.01). Furthermore, expressions of IGF-I and MyoG genes showed highly significant positive correlations (P < 0.01). We conclude that the expressions of IGF-I and MyoG genes are significantly and positively correlated with early muscle traits of Hu sheep.

Abstract
Congenital heart disease (CHD) is the most common birth abnormality, but the etiology of CHD is unknown. ISL1 may play a fundamental role in cardiac morphogenesis, and mutations of this gene could cause CHD. To evaluate whether genetic variations of ISL1 are associated with CHD in Chinese Han people, polymerase chain reaction restriction fragment-length polymorphism and SNaPshot were used to examine 9 polymorphisms of ISL1 in 233 patients with CHD as well as 288 healthy controls. We found that one SNP (rs1017) in ISL1 was significantly associated with simple CHD. Genetic variation of ISL1 was confirmed to be associated with the risk of CHD. ISL1 is related to the atrial septal defect group and the ventricular septal defect group, and the genotypes were associated with the occurrence of CHD in the dominant mode of inheritance. We concluded that rs1017 contributed to the risk of CHD in Chinese Han people, and ISL1 may be involved in the formation and development of the heart.
