Abstract
Orychophragmus violaceus (OV) and chicory (Cichorium intybus L., CC) can be used as fresh or dry forage for animals. To determine whether OV and/or CC have beneficial effects on performance and egg quality, a total of 1212 28-wk-old Beijing You Chicken (BYC) laying hens with similar performance were randomly allocated to 4 groups with 3 replicate pens per group, and 101 birds per pen. The birds were fed a basal diet (control), the basal diet + OV (3.507 kg/d/pen), the basal diet + CC (2.525 kg/d/pen), and the basal diet + OV + CC (OVC, 1.7535 kg/d/pen OV + 1.2625 kg/d/pen CC) for 3 wks after one wk of adaptation. The results showed that egg-laying rate was not affected by OV, CC and OVC (p > 0.05), but weekly average egg mass was significantly increased by OV and CC (p < 0.05). The feed egg ratio in the CC group (2.82) was significantly lower than that in the other three groups (p < 0.05). The eggshell thickness (EST), albumen height (AH) and Haugh unit (HU) were decreased by OV and CC (p < 0.05); while yolk color (YC) was increased in the CC and OVC groups (p < 0.05). Egg grade was decreased by OV (p < 0.05). Sensory evaluation showed that there was a trend for increased YC in OV, CC and OVC (p = 0.089). Serum total protein was significantly lower in OV group than those in the control and CC group (p < 0.05); serum albumin content was significantly decreased in OV, CC and OVC groups (p = 0.006). Serum glutathione peroxidase activity in CC and OVC groups was significantly higher than that in the control group (p < 0.05). In conclusion, the present study suggests that CC had a better effect on the performance of the native laying hens than OV. The OV and CC affected egg quality, while YC was increased in CC and OVC groups. The OVC improved YC and serum antioxidative properties of native laying hens without affecting the performance.

Abstract
Objective: To explore the evaluation effect of ultrasonography and Pirani score on tarsal deformity, treatment effect and pseudo-correction of congenital clubfoot in infants and young children, and the correlation between the two methods. Methods: This is a retrospective case series study. The clinical data of 26 children (40 feet) with congenital clubfoot who were evaluated by ultrasonography in the Third Affiliated Hospital of Zhengzhou University from January 2020 to January 2023 were retrospectively collected. There were 16 males and 10 females. The age at the first ultrasound examination was (M(IQR)) 9.0 (18.0) days (range: 1 to 46 days). All patients were treated with Ponseti method by the same physician. The Pirani scores before and after treatment and at the last examination, and the talonavicular angle, calcaneocuboid angle and tibiocalcaneal angle measured by ultrasound were collected, and the treatment and follow-up were recorded. Paired sample t test, repeated measures analysis of variance or Kruskal-Wallis test were used for data comparison, and Spearman correlation analysis was used for correlation analysis. The receiver operating characteristic curve was used to calculate the efficacy of ultrasound in evaluating different Pirani scores. Results: The number of plaster fixation in 26 children was 4.0 (1.0) times (range: 2 to 8 times). The medial talonavicular angle and posterior tibiocalcaneal angle were significantly improved after treatment and at the last follow-up compared with those before treatment, and the differences were statistically significant (all P<0.01). There was no difference in lateral calcaneocuboid angle before and after treatment and at the last follow-up (F=1.971, P>0.05). Pseudo-correction occurred in 2 cases (2 feet) during the treatment, with an incidence of 5%. Correlation analysis showed that there was a moderate positive correlation between talonavicular angle and Pirani midfoot score (r=0.480, P<0.01). There was no correlation between calcaneocuboid angle and Pirani midfoot score (r=0.114, P=0.105). There was a moderate negative correlation between tibial heel angle and Pirani hindfoot score (r=-0.566, P<0.01). The cut-off point of Pirani midfoot score of 1.5 was 38.78°, the sensitivity was 0.90, the specificity was 0.56, and the area under the curve was 0.75. The cut-off value of angle was 27.51 °, the sensitivity was 0.16, the specificity was 0.92, and the area under the curve was 0.44.The cut-off points of Pirani midfoot score of 3.0 were 45.08°and 9.96°, the sensitivity was 0.94 and 0.91, the specificity was 0.37 and 0.42, and the area under the curve was 0.59 and 0.62, respectively. The cut-off values of Pirani hindfoot score of 2.0 and 3.0 were 167.46° and 160.15°, respectively. The sensitivity was 0.75 and 0.67, the specificity was 0.81 and 0.83, and the area under the curve was 0.78 and 0.71, respectively. Conclusion: Ultrasound can complement with Pirani score, visually and dynamically observe the morphology and position changes of talonavicular joint, calcaneocuboid joint and tibiotalocalcaneal joint, monitor the recovery and pseudo-correction of tarsal bones, and better evaluate the therapeutic effect.

Abstract
Chronic hepatitis C is a kind of viral hepatitis caused by hepatitis C virus infection, which can further progress to cirrhosis, liver failure, hepatocellular carcinoma, and even death. Presently, there is no preventive vaccine yet. Therefore, preventing infection and safe and effective drug treatment are currently the most effective strategies for dealing with hepatitis C virus infection. Since 2014, the clinical application of direct-acting antiviral drugs has brought revolutionary changes to the treatment of chronic hepatitis C. Direct-acting antiviral drugs have an excellent hepatitis C virus clearance effect, are well tolerated, have a good safety profile, and can significantly improve liver function, metabolic disorders, immune dysfunction, etc. However, some studies have pointed out that even if the hepatitis C virus is cleared during the treatment of chronic hepatitis C-related cirrhosis with direct-acting antiviral drugs, a considerable proportion of patients still have severe liver failure, hepatocellular carcinoma, and even liver disease-related death, so there are still some problems in the treatment of chronic hepatitis C- related cirrhosis with direct-acting antiviral drugs that need to be further explored. This article reviews the research progress of direct-acting antiviral drugs so as to provide meaningful references for the treatment of patients with chronic hepatitis C-related cirrhosis.

Abstract
Objective: To summarize the resistance of rifampicin-resistant Mycobacterium tuberculosis to anti-tuberculosis drugs in group A. Methods: In the retrospective study, a total of 1 226 clinical isolates from suspected multidrug-resistant pulmonary tuberculosis patients in Beijing TB control system from 2016 to 2021 were identified as Mycobacterium tuberculosis (MTB) strains by MPB64 antigen detection test. Rifampicin-resistant tuberculosis (RR-TB) strains were screened by the phenotypic drug susceptibility using the proportion method. The drug susceptibilities of Levofloxacin(LFX), Moxifloxacin(MFX), Bedaquiline(BDQ) and Linezolid(LZD)were detected by the phenotypic drug susceptibility with microplate method. The drug resistance rate, drug resistance level and minimum inhibitory concentration (MIC) distribution of four anti-tuberculosis drugs in group A were analyzed. We calculated the demographic distribution of RR-TB, multidrug-resistant tuberculosis(MDR-TB), pre-extensively drug resistant tuberculosis (pre-XDR-TB), extensively drug resistant tuberculosis (XDR-TB) patients and the cross resistance of LFX and MFX, then summarized the drug-resistance spectrum of BDQ-resistant and LZD-resistant strains and the treatment outcome of RR-TB patients. Measurement data were expressed as rate or composition ratio,χ2 test was used between and within groups, and P<0.05 was considered statistically significant. Results: Among the 1 226 suspected multidrug-resistant pulmonary tuberculosis patients, the detection rates of RR/MDR/pre-XDR/XDR-TB patients were 20.8%(255/1 226), 15.2%(186/1 226), 5.7%(70/1 226), 0.5%(6/1 226), respectively. There were statistically significant differences in the distribution of patients with the four types of drug resistance in terms of age and treatment history (χ2=14.95, P=0.020;χ2=15.91, P=0.001). The drug resistance rates of LFX, MFX, BDQ and LZD in RR-TB patients were 27.5% (70/255), 27.5% (70/255), 0.4% (1/255) and 2.4% (6/255), respectively. The MICs of LFX, MFX and LZD-susceptible MTB were mainly at 0.25 mg/L, and the MIC of BDQ-susceptible MTB was mainly concentrated at 0.03 mg/L. 25.1% (64/255) of the RR MTB were resistant to both LFX and MFX, and 6 strains were resistant to LFX or MFX, showing incomplete two-way cross resistance. One BDQ-resistant strain and six LZD-resistant strains were detected. The treatment success rate of RR-TB patients was 74.4% (151/203), and there were statistically significant differences in treatment outcomes between resistant and sensitive patients on the LFX-containing treatment regimen (Fisher's exact test, P=0.012). Conclusions: The prevalence of fluoroquinolones (LFX and MFX) resistance in rifampicin-resistant MTB is very serious. LFX and MFX show incomplete bidirectional cross-resistance. BDQ and LZD have the most promising future in the treatment of MDR-TB. Improve drug-resistance testing will help to further improve the success rate of treatment.

Abstract
Objective: To analyze the epidemic characteristics and drug resistance of pulmonary tuberculosis among the floating population in Beijing and to provide a scientific basis for formulating strategies for the prevention and control of tuberculosis among the floating population. Methods: Data of tuberculosis patients who were positive for Mycobacterium tuberculosis culture was collected from 16 districts and one municipal institution of tuberculosis control and prevention in Beijing in 2019. The strain samples were tested for drug sensitivity by the proportional method. According to household registration location, patients were divided into the floating population and Beijing registration. SPSS 19.0 software analyzed tuberculosis patients' epidemic characteristics and drug resistance in the floating population. Results: In 2019, there were 1 171 culture-positive tuberculosis patients in Beijing, among the floating population, 593 (50.64%) patients were identified, with a male-to-female sex ratio of 2.2∶1 (409∶184). Compared to patients under household registration as Beijing residents, a higher proportion of young adults aged 20-39 years (65.09%,386/593) were noticed, with 55.65% (330/593) reported from the urban areas and 96.80% (574/593) were reported the first time. The differences were statistically significant (all P<0.05). After completing the drug sensitivity test, 37 cases were with multiple drug-resistant tuberculosis, accounting for 6.24% (37/593). The rates of isoniazid resistance (42.11%,8/19) and multidrug resistance (21.05%,4/19) in floating population patients after retreatment were significantly higher than those in newly treated patients (11.67%, 67/574 and 5.75%, 33/574), and the differences were statistically significant (all P<0.05). Conclusions: Most patients with tuberculosis in the floating population in Beijing in 2019 were young males aged 20-39 years. The reporting areas were urban areas and the newly treated patients mainly. The patients with tuberculosis in the re-treated floating population were more likely to suffer from multidrug and drug resistance, which should be taken as the key population for prevention and control.

Abstract
Objective: To evaluate the efficacy and safety of intravenous iron supplementation in patients with recurrent iron deficiency anemia (IDA) . Methods: This retrospective analysis of 90 patients with recurrent IDA from May 2012 to December 2021 was conducted, comparing the efficacy and safety of the intravenous iron therapy group and the oral iron therapy group. Results: Among the 90 patients with recurrent IDA, 20 were males and 70 were females, with a median age of 40 (range: 14-85) years. A total of 60 patients received intravenous iron supplementation and 30 received oral iron supplementation. The hematologic response rates in the intravenous iron group were significantly higher than those in the oral iron group at 4 and 8 weeks after treatment [80.0% (48/60) vs 3.3% (1/30) and 96.7% (58/60) vs 46.7% (14/30), all P<0.001, respectively]. The median increase in hemoglobin levels was also significantly higher in the intravenous iron group than in the oral iron group [38 (4, 66) g/L vs 7 (1, 22) g/L at week 4 and 44.5 (18, 80) g/L vs 19 (3, 53) g/L at week 8, all P<0.001]. The intravenous iron group had a significantly higher proportion of patients who achieved normal hemoglobin levels than the oral iron group (55.0% vs 0 and 90% vs 43.3%, all P<0.001, respectively). Iron metabolism indicators were tested before and after 8 weeks of treatment in 26 and 7 patients in the intravenous and oral iron groups, respectively. The median increase in serum ferritin (SF) levels in the intravenous iron group 8 weeks after treatment was 113.7 (49.7, 413.5) μg/L, and 54% (14/26) of these patients had SF levels of ≥100 μg/L, which was significantly higher than the median increase in SF levels in the oral iron group [14.0 (5.8, 84.2) μg/L, t=4.760, P<0.001] and the proportion of patients with SF levels of ≥100 μg/L (P=0.013). The incidence of adverse reactions was 3.3% (2/60) in the intravenous iron group, which was significantly lower than that in the oral iron group [20.0% (6/30), P=0.015]. Conclusion: Intravenous iron supplementation is more effective for hematologic response, faster hemoglobin increase, and higher iron storage replenishment rates compared with oral iron supplementation in patients with recurrent IDA, and it is well tolerated by patients.

Abstract
Major depressive disorder (MDD) is one of the most prevalent psychiatric illnesses worldwide which impairs the social functioning of the afflicted patients. Astrocytes promote homeostasis of the CNS and provide defense against various types of harmful influences. Increasing evidence suggests that the number, morphology and function of astrocytes are deteriorated in the depressed brain and the malfunction of the astrocytic purinergic system appears to participate in the pathophysiology of MDD. Adenosine 5'-triphosphate (ATP) released from astrocytes modulates depressive-like behavior in animal models and probably also clinical depression in patients. Astrocytes possess purinergic receptors, such as adenosine A2A receptors (Rs), and P2X7, P2Y1, and P2Y11Rs, which mediate neuroinflammation, neuro(glio)transmission, and synaptic plasticity in depression-relevant areas of the brain (e.g. medial prefrontal cortex, hippocampus, amygdala nuclei). By contrast, astrocytic A1Rs are neuroprotective and immunosuppressive. In the present review, we shall discuss the release of purines from astrocytes, and the expression/function of astrocytic purinergic receptors. Subsequently, we shall review in more detail novel evidence indicating that the dysregulation of astrocytic purinergic signaling actively contributes to the pathophysiology of depression and shall discuss possible therapeutic options based on knowledge recently acquired in this field.

Abstract
Objective: To evaluate the predictive value of neutrophil-lymphocyte ratio (NLR) on admission and before discharge for long-term all-cause death (ACD) in patients hospitalized with heart failure with reduced ejection fraction (HFrEF). Methods: Patients hospitalized and discharged from hospital alive with the clinical diagnosis of HFrEF in cardiac care unit (CCU) of TEDA International Cardiovascular Hospital from January 2013 to December 2017 were consecutively enrolled. NLR, which was defined as neutrophil counts divided by lymphocyte counts, was measured 1 day within admission and 3 days before discharge to evaluate the prognostic value of admission NLR in combination with discharge NLR for the ACD after discharge by using of multivariate Cox regression analysis. Patients were followed-up until December 2020 or ACD. Results: A total of 368 patients hospitalized with HFrEF were enrolled with an age of (54±14) years, including 79 females (21.5%). During the median (inter-quartile range, IQR) duration of follow-up after discharge of 30 (10, 60) months, 95 patients died, thus, the rate of ACD was 25.8%. Multivariate Cox regression analysis showed that the NLR level before discharge was an independent predictor of ACD after discharge [hazard ratio (HR)=1.143, 95% confidence interval (CI) 1.048-1.248, P=0.003] after adjusting for other parameters such as systolic blood pressure on admission and at discharge, left ventricular end-diastolic diameter on admission, and usage of aldosterone receptor blockers at discharge. Moreover, compared to those with NLR level at admission ≤2.25 and ≤2.00 before discharge, the long-term risk of ACD after discharge was nearly doubled for patients with NLR level at admission>2.25 and>2.00 before discharge (adjusted HR=1.968, 95%CI 1.198-3.234, P=0.008). Conclusions: The NLR level before discharge was an independent predictor of ACD after discharge for patients hospitalized with HFrEF. Combining NLR levels at admission and before discharge help to better predictive the risk of long-term ACD after discharge.

Abstract
The lymph node ratio (LNR) has been proposed as an independent prognostic factor for survival in patients with oral squamous cell carcinoma (OSCC). However, little attention has been paid to its role in the specific subsite of the floor of the mouth (FOM). The purpose of this study was to evaluate the prognostic significance of the LNR in patients with FOM SCC. A retrospective analysis of 92 patients with FOM SCC who were treated with primary curative resection and neck dissection was conducted. Overall survival (OS) and disease-free survival (DFS) were used to evaluate the prognostic significance of the LNR. Both of these parameters were significantly worse (P < 0.001) in patients with neck metastases. The mean LNR was 0.145 in patients with positive lymph nodes. A LNR <0.145 was predictive of longer DFS, while the receiver operating characteristic curve analysis demonstrated that a LNR ≥0.175 indicated a significantly lower OS. This study confirms that metastatic cervical lymph nodes correlate with an adverse prognosis in patients with FOM SCC, and specifically, a LNR ≥0.145 is predictive. Therefore, the LNR in patients with FOM SCC may be a predictor of survival in these patients.

Abstract
Spin-valley locking in monolayer transition metal dichalcogenides has attracted enormous interest, since it offers potential for valleytronic and optoelectronic applications. Such an exotic electronic state has sparsely been seen in bulk materials. Here, we report spin-valley locking in a Dirac semimetal BaMnSb2. This is revealed by comprehensive studies using first principles calculations, tight-binding and effective model analyses, angle-resolved photoemission spectroscopy measurements. Moreover, this material also exhibits a stacked quantum Hall effect (QHE). The spin-valley degeneracy extracted from the QHE is close to 2. This result, together with the Landau level spin splitting, further confirms the spin-valley locking picture. In the extreme quantum limit, we also observed a plateau in the z-axis resistance, suggestive of a two-dimensional chiral surface state present in the quantum Hall state. These findings establish BaMnSb2 as a rare platform for exploring coupled spin and valley physics in bulk single crystals and accessing 3D interacting topological states.

Abstract
Objective: To explore the clinical manifestations, imaging features, pathological features, diagnosis and treatment of pulmonary mucosal-associated lymphoid tissue(MALT)lymphoma concurrent with lung squamous cell carcinoma, and to improve the understanding of this disease. Methods: Using "Pulmonary mucosa-associated lymphoid tissue, squamous cell carcinoma" as the search term, from January 1, 1983 to August 31, 2020, a total of 3 cases were retrieved in the PubMed database. In the Wanfang database, using "Lung mucosa-associated lymphoid tissue, lung squamous cell carcinoma" as the search term, from January 1, 1990 to August 31, 2020, a total of 1 related document was retrieved. In the CNKI database, "(lung) mucosa-associated lymphoid tissue lymphoma, (lung) squamous cell carcinoma" was used as the search term, and no relevant case reports were retrieved. Results: A 64-year-old man was admitted to the hospital because of chest tightness and shortness of breath for 10 days, cough and fever for one day. Enhanced CT of the chest showed a soft tissue mass shadow in the right lower hilar area, with obstruction of the adjacent bronchus, and local mild enhancement, suggesting of right lower lung cancer. In addition, the CT scan also showed consolidated shadows in the lower lobes of both lungs, scattered nodules, multiple lymphadenopathy in the mediastinum, and a small amount of pleural effusion on the right. Under bronchoscopy, a cauliflower-like neoplasm was seen at the opening of the lower right basal section, about 7 mm×8 mm, and biopsy showed that part of the mucosal structure was destroyed, with disappearance of the squamous epithelial layer, and the nuclei were large and deeply stained, and some were distributed in nests, with poor keratinization and a small amount of necrosis, and fibrous tissue reaction. Immunostaining revealed that the tumor was positive for p40, CK5/6 and EGFR and negative forTTF-1, NapsinA, PD-L1, p53, with about 30% Ki-67 positive cells. A puncture biopsy of the right lower lobe showed that the alveolar cavity was filled with nested lymphoid cells, consisting of small lymphocytes, central cell-like cells and monocyte-like cells, with occasionally large cells. Immunostaining revealed CD20+, CD79a+, scattered CD3+, Bcl2+, SMA vascular+, Bcl6-, CK-, CD10-, CyclinD1-, with about 3% Ki-67 positive cells. The histopathological examinations confirmed the diagnosis of mucosal-associated lymphoid tissue extranodal marginal zone lymphoma(MALT lymphoma),and lung squamous cell carcinoma. Conclusions: Pulmonary mucosa-associated lymphoid tissue lymphoma complicated with lung squamous cell carcinoma is rare and easy to be missed and misdiagnosed. Chest CT imaging shows single or multiple nodules, mass shadows or consolidation, often accompanied by air-bronchial signs in the lesion, bronchiectasis, ground glass density around the lesion, hilar and mediastinal lymphadenopathy. Occasionally, pleural effusion can be seen. Lung biopsy is the gold standard for diagnosis.

Abstract
Objective: To explore the relationship between premature atrial complexes (PACs) and recurrence of atrial fibrillation (AF). Methods: Published literature was searched in PubMed, Embase, Web of Science, Cochrane, Weipu, China national knowledge infrastructure, Wanfang and China Biology Medicine disc up to 25 March 2020. RevMan5.3 software was used to analyzed the data and publication bias was performed by Stata 15.1. Results: A total of 8 studies were identified, including 1 252 AF patients with a mean age of 61.67 years, and male patients accounted for 70.6%. During follow-up, AF recurred in 425 cases. Meta-analysis showed that frequent PACs was an independent risk factor for recurrence of AF (HR=2.64, 95%CI:1.40-4.97). Subgroup analyses showed that PACs not only increasedthe risk of recurrence of AF after electrical cardioversion (HR=2.38, 95%CI:1.25-4.51), but also significantly increased the risk of recurrence of AF after catheter ablation cardioversion (HR=2.90, 95%CI:1.11-7.60). Conclusions: PACs is significantly associated with AF recurrence.

Abstract
BACKGROUND Colorectal cancer (CRC) has emerged as a major public health concern. However, little is known about the burden attributable to specific risk factors. The present study aimed to estimate the temporal trends and geographical variation of CRC burden attributable to a diet low in milk in China. METHODS Following the general analytic strategy used in the 2017 Global Burden of Disease study, we assessed the age-, sex-, and province-specific mortality and disability-adjusted life-years (DALYs) of CRC caused by a diet low in milk in China from 1990 to 2017. RESULTS In 2017, a diet low in milk contributed 32 032 [95% uncertainty interval (UI) = 11 350-53 806] deaths and 726 710 (95% UI = 256 651-1 218 153) DALYs for CRC with a population attributable fraction of 17.1%. The age-standardised mortality and DALY rates per 100 000 were 1.7 (95% UI = 0.6-2.9) and 36.8 (95% UI = 13.0-61.7), respectively. An upward trend with age in rates of mortality and DALYs was observed. Males had higher age-standardised rates than females. The number of deaths and DALYs increased significantly from 1990 to 2017, whereas the corresponding age-standardised rates showed relatively stable trends. In 2017, Hunan and Liaoning were ranked as the top two provinces in terms of disease burden. Socio-demographic index had a weak correlation with the age-standardised mortality (r = 0.348, P = 0.047). CONCLUSIONS The present study shows a substantial increase in the CRC burden attributable to a diet low in milk over the past three decades. Greater priority in CRC prevention should be given to males and the elderly population throughout China, particularly in less-developed provinces.

Abstract
Objective: To analyze the correlation of phthalate metabolites in neonatal umbilical cord blood with birth indicators in Beijing, 2015. Method: From February to July in 2015, 161 pregnant women and their newborns who met the criteria were recruited from the Maternal and Child Health Hospital in Haidian District, Beijing. Questionnaires were used to collect the demographic information of pregnant women such as age, smoking, drinking, and cord blood after delivery. An ultra-high performance liquid chromatography-tandem mass spectrometry was used to determine the concentration of phthalate metabolites in umbilical cord blood. The multiple linear regression model was used to analyze the correlation of phthalate metabolites in umbilical cord blood with the neonatal weight, length, and ponderal index. Result: The age of 161 pregnant women was (30.3±3.0) years. The weight, length and ponderal index of 161 newborns were (3 447.2±413.0) kg, (50.2±1.1) cm, and (26.7±2.2) kg/m3; 51.6% of newborns (83 cases) were boys. The concentrations of seven phthalate metabolites detected in umbilical cord blood, i.e., mono-methyl phthalate (MMP), mono-ethyl phthalate (MEP),mono-(2-isobutyl) phthalate (MiBP), mono-n-butyl phthalate (MBP), mono-ethylhexyl phthalate (MEHP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP), and mono-(2-ethyl-5-carboxypentyl) phthalate (MECPP), was (3.50±0.28), (2.65±0.47), (4.31±0.55), (6.26±0.57), (1.71±0.13), (1.10±0.09) and (0.47±0.06) ng/ml, respectively. The result of multiple linear regression model analysis showed that the concentrations of seven phthalate metabolites were not related to the neonatal weight, length, and ponderal index (all P values> 0.05). Conclusion: The concentrations of phthalate metabolites in neonatal umbilical cord blood are low, and they are not related to the neonatal weight, length, and ponderal index.

Abstract
Metastable high entropy alloys (HEAs) have attracted extensive attention due to their excellent combination of high strength and great plasticity. In this work, we utilize constraining effects to tailor phase transformation strengthening and plasticity of nanostructured HEA ([double bond, length as m-dash]FeCoCrNi) thin films prepared by the magnetron sputtering technique via HEA/Cu and HEA/Ni nanotwinned nanolaminates (NTNLs). It is uncovered that the HEA/Cu NTNLs without phase transformation exhibit the fashion of "smaller is stronger" and HEA layers become more favorable to detwin at a smaller layer thickness (h). By contrast, the HEA/Ni NTNLs manifest an ultra-high peak hardness plateau accompanied by the FCC-to-HCP phase transformation in HEA layers at large h≥ 25 nm, whereas they manifest size-dependent hardness when detwinning occurs at smaller h. This unusual plastic deformation behavior of HEA/X (X = Cu, Ni) NTNLs was rationalized by partial-based mechanisms. These findings open a new avenue to achieve superior mechanical properties of HEAs particularly at the nanoscale.

Abstract
PURPOSE Liquid water being the major constituent of the human body, is of fundamental importance in radiobiological research. Hence, the knowledge of electron-water interaction physics and particularly the secondary electron yield is essential. However, to date, only very little is known experimentally on the low energy electron interaction with liquid water because of certain practical limitations. The purpose of this study was to gain some useful information about electron emission from water using a Monte Carlo (MC) simulation technique that can numerically model electron transport trajectories in water. METHODS In this study, we have performed MC simulations of electron emission from liquid water in the primary energy range of 50 eV-30 keV by using two different codes, i.e., a classical trajectory MC (CMC) code developed in our laboratory and the Geant4-DNA (G4DNA) code. The calculated secondary electron yield and electron backscattering coefficient are compared with experimental results wherever applicable to verify the validity of physical models for the electron-water interaction. RESULTS The secondary electron yield vs. primary energy curves calculated using the two codes present the same generic curve shape as that of metals but in rather different absolute values. G4DNA underestimates the secondary electron yield due to the application of one step thermalization model by setting a cutoff energy at 10 eV so that the low energy losses due to phonon excitations are omitted. Our CMC code, using a full energy loss spectrum to model electron inelastic scattering, allows the simulation of individual phonon scattering events for very low energy losses down to 10 meV, which then enables the calculated secondary electron yields much closer to the experimental data and also gives quite reasonable energy distribution curve of secondary electrons. CONCLUSIONS It is concluded that full dielectric function data at low energy loss values below 10 eV are recommended for modeling of low energy electrons in liquid water.

Abstract
Objective: To understand the status and health risk assessment of dietary fipronil contamination among 20 provinces of China. Methods: A total of 13 kinds of dietary samples in Chinese total diet study include cereals, legumes, potatoes, meats, eggs, aquatics, dairies, vegetables, fruits, sugars, beverages and water, alcohols, condiments and their corresponding products. Among them, condiments were used in the preparation of 12 other sample categories; thus, the actual mixed dietary samples of each province covered 12 groups. A total of 240 mixed dietary samples were collected from 20 provinces in China from 2009 to 2013. After the sample extraction and cleanup, dietary samples were analyzed for the residues of fipronil and its metabolites to obtain the contamination levels of fipronil residues using liquid chromatography-high resolution mass spectrometry. The dietary intake of adult residents was estimated based on food consumption of general population of China. Results: Among the 240 dietary samples, the detection rate of fipronil was 10.4% (25 samples), and the detection rates of fipronil metabolites, i.e. fipronil desulfinyl, fipronil sulfone and fipronil sulfide were 20.4% (49 samples), 40.0% (96 samples) and 8.8% (21 samples), respectively. According to the dietary exposure analysis, the average lower and upper dietary exposure levels of fipronil residues in adult residents of China were 11.34 and 12.35 ng·kg(-1)·d(-1), accounting for 5.7% and 6.2% of acceptable daily intake (ADI), respectively. The highest adult dietary intake of fipronil residues was found in Hunan province, with a value of 72.98 ng·kg(-1)·d(-1), accounting for 36.5% of ADI. Vegetables were the main dietary source of fipronil residues, which contributed to 71.0% of the total intake dose. Conclusion: Fipronil residues were detected in varying degrees in dietary samples, yet the health risk caused by the dietary intake of adult residents among 20 provinces of China is low.

Abstract
Background To introduce a modified pleurodesis as an effective treatment for refractory chylothorax and to develop a novel insight for its mechanism. Methods Patients who underwent thoracic surgery at West China Hospital or its affiliated hospitals between 2010 and 2015 and who subsequently experienced chylothorax that was not resolved by conventional treatment, received daily pleurodesis involving 100 mL 50% glucose and 20 mL 1% lidocaine. The chest tube was clamped after 7 days of pleurodesis, regardless of drainage amount. If no remarkable pulmonary atelectasis was detected within 2 days, the chest tube was removed. All patients were followed up with for at least 3 months after discharge from our hospital. Results Among the 34 patients, 10 did not experience an increase in the pleural fluid after the chest tube was clamped. Minor effusion increase occurred in 21 patients, while encapsulated effusion occurred in 3. In 23 patients among the latter 24 patients, pleural fluid was gradually absorbed and disappeared spontaneously. One patient suffered chylothorax recurrence after discharge but successfully recovered after the second round of modified pleurodesis. Several patients suffered from electrolyte imbalance, weakness, and dyspnea; all were cured by plasma infusion and other symptomatic treatments. Conclusions Being safe and effective for patients with postoperative refractory chylothorax, our modified pleurodesis enhanced the process of chemical pleurodesis and could remove the chest tube right after the extensive adhesion formed instead requiring a wait for drainage decrease. This method can thus shorten the period of hospitalization and reduce fluid loss compared with traditional pleurodesis.

Abstract
Objective: To quantify the effects of short-term walking intervention on body mass index (BMI), waist circumference, and related indicators of working population. Methods: The China Motivational Healthy Walking Program in 2016 recruited 29 224 individuals from 139 demonstration areas for comprehensive prevention and control of chronic and non-communicable diseases at the national level and 70 areas at the provincial level. All subjects volunteered to participate into this program. The intervention lasted 100 days from June to September 2016. The walking behavior, height, weight and waist circumference of subjects were measured using a uniform pedometer, body composition tester, height tester and waist-to-hip caliper before and after the intervention. Daily average steps, daily average effective steps, and the percent of fulfilling continuous walking per day were used as main indicators in this study. Self-administered questionnaires were used to collect demographic characteristics, behaviors and chronic diseases. With the adjustment of potential confounding factors, multilevel regression was used to quantify the effect of walking on BMI and waist circumference, and multilevel logistic regression was used to quantify the effect on overweight or obesity and central obesity. Results: A total of 12 368 subjects completed walking interventions and all measurements included in this study. The mean±SD age of all subjects was (41.19±8.99) years, and 5 155 (59.17%) of them were women. After 100-day intervention, all outcome variables decreased significantly. For every additional 1 000 steps per day, subjects would have extra decrease in BMI of 0.023 kg/m(2) [β (95%CI): -0.023 (-0.030, -0.017)], in waist circumference of 0.046 cm [β (95%CI): -0.046 (-0.071, -0.020)], and the likelihood for becoming overweight or obesity was 0.97 times [OR (95%CI): 0.97 (0.95, 0.98)] that of before intervention. With additional 1 000 effective steps per day, the difference between baseline and endpoint increased by 0.028 kg/m(2) [β (95%CI): -0.028 (-0.035, -0.020)] in BMI and 0.062 cm [β (95%CI): -0.062 (-0.091, -0.033)] in waist circumference. The likelihood of progressing into overweight or obesity was 0.97 times [OR (95%CI): 0.97(0.95, 0.98)] that of before-intervention, and the likelihood of becoming central obesity was 0.98 times [OR (95%CI): 0.98(0.96, 0.99)] that of before-intervention. Compared to subjects with low level percent of fulfilling continuous walking per day, those with high level would have an extra decrease in BMI by 0.150 kg/m(2) [β (95%CI): -0.150 (-0.22, -0.079)], in waist circumference by 0.340 cm [β (95%CI): -0.340 (-0.620, -0.064)], and the likelihood of becoming overweight or obesity decreased to 0.74 times that of the low level group [OR (95%CI): 0.74(0.62, 0.89)] and the likelihood of becoming central obesity decreased to 0.78 times that of the low level group [OR (95%CI): 0.78 (0.68, 0.91)]. Conclusion: Strengthening walking exercise in the short term has a positive effect on promoting working population to reduce BMI and waist circumference, and prevent overweight, obesity and central obesity.

Abstract
Objective: To explore the association between dietary pattern which benefit for normal kidney function and the risk of cognitive decline or impairment in the elderly. Methods: In 2015, subjects aged 60 and over from four counties in the Nutrition and Chronic Disease Family Cohort project, were followed up in 2017. Cognitive function was repeatedly assessed, using the Mini Mental State Evaluation (MMSE) scale. Dietary pattern that benefit for normal kidney function was extracted, using the reduced rank regression method and followed by logistic regression models to explore the associations between scores that showing the kidney function on dietary patterns and the risk of cognitive deterioration and impairment in two years among those who were with normal cognition in 2015. Results: Dietary pattern that benefit for normal kidney function, was characterized by high consumption of cereal, vegetables, legume and fruits but with less meat and soy products. Comparing with the group with lowest score quartile on this dietary pattern, the risk of cognitive deterioration in the highest quartile group was significantly low (P<0.01) in two years, with an odds ratio as 0.57 (95%CI: 0.37-0.85). Linear trend was also obviously visible (P=0.007) in this group. The ones at the highest quartile group among the normal cognition ones in 2015, the risk of cognitive impairment also significantly reduced (P<0.05) in two years time, with an odds ratio as 0.52 (95%CI: 0.29-0.93). Also, linear trend could obviously be seen (P=0.01). Conclusion: Dietary pattern that benefit for normal kidney function was both inversely associated with cognitive deterioration and impairment, in two years.

Abstract
Compared with coarse-grained FeCoCrNi-based high entropy alloys (HEAs), their nanocrystalline (NC) siblings with ultra-high strength often suffer from notably reduced deformability. Here, to enhance the deformability of these NC HEAs without losing their high strength, we design equal layered nanotwinned (NT) Cu/HEA (HEA = FeCoCrNi) crystalline/crystalline nanolaminates (C/CNLs) with coherent crystalline/crystalline interfaces (CCIs). In contrast to the tenet that in conventional bimetal C/CNLs, the soft/ductile phase plays the dominant major role, we discover that in NT Cu/HEA C/CNLs, the hard HEA phase unusually makes more contribution to the plastic deformation. The underlying reason is that the soft NT Cu layers without dislocation pile-up serve as the dislocation donator and export abundant dislocations that transmit across the coherent CCIs into the hard HEA accepter, and thus trigger their great deformability. The size-dependent hardness was explained based on dislocation-based models considering the stability of extremely small nanotwins with thickness less than ∼10 nm. These findings provide a new pathway to achieve great deformability of strong alloys with high lattice friction stresses in ultra-strong metallic composites: control the size of NT soft phases to suppress dislocation pile-up in conjunction with coherent CCIs to facilitate continuity of dislocation slip.

Abstract
Objective: There is no effective therapy for patients with advanced medullary thyroid carcinoma (MTC). Vandetanib,a novel multitargeted receptor tyrosine kinase inhibitor, has previously shown antitumor activity in phase Ⅱ studies of patients with advanced MTC. This study was to evaluate the efficacy and the safety of vandetanib on advanced MTC. Methods: This study was an open, international multi-center phase Ⅲ clinical trial and the study number was NCT01298323. The single-center study was a sub-group analysis of the international study, which was conducted on 9 pathologically confirmed advanced MTC patients by Cancer Hospital Chinese Academy of Medical Sciences between March 2012 and October 2017. Vandetanib (300 mg) was orally administered daily till death or withdrawal. The efficacy was evaluated according to RECIST criteria and the adverse events were evaluated according to NCI criteria. Results: The objective response rate was 3/9,and the disease control rate was 4/9. The median progression-free survival was 44 months. All patients who had the elevated levels of calcitonin (CTN) and carcino-embryonic antigen (CEA) before treatment began to show the decreases in the level of CTN and CEA after 3 months and later showed again the increases in the levels of both tumor markers with tumor progression. By ROC curve analysis, CTN was of statistically significance(P<0.05, 95%CI 0.558-0.834), but CEA was not(P>0.05). Adverse events were generally mild (grade 1 or 2),including hypertension (9 cases),skin rash (9 cases), and diarrhea (6 cases). Two patients developed grade 3 elevation of serum glutamate pyruvate transaminase and one patient developed grade 3 elevation of drug-related bowel disease. No grade 4 drug-related adverse event occurred. Conclusions: Vandetanib is effective and well tolerated for patients with locally advanced or metastatic MTC who have no chance for surgery. This indicates the increase of CTN is clinically relevant to disease progression, but the number of patients are extremely low, and, therefore further research is needed. Long-term use of vandetanib may cause resistance.

Abstract
Objective: To analyze the lung cancer deaths attributable to ambient PM(2.5) exposure in China in 2016. Methods: All data were from the Global Burden of Disease Study 2016 (GBD 2016). Multiple-source data, including satellite observation, ground measurement, chemical migration model simulation, etc., and the data integration model for air quality (DIMAQ) were used to estimate the grid-level exposure to ambient PM(2.5). Data from the vital registry and cancer registry were used to establish statistical model to estimate the lung cancer deaths by province, age and gender. The lung cancer deaths attributable to PM(2.5) were calculated based on the calculation of population attributable fraction (PAF). The GBD world population age structure was adopted to calculate age-standardized rates for comparison among provinces (including 31 provinces, autonomous regions and municipalities directly under the central government, as well as Hong Kong and Macao special administrative regions, excluding Taiwan of China). Results: In 2016, the lung cancer deaths attributable to ambient PM(2.5) exposure in China were 14.56×10(4) (95% uncertainty interval (UI): 9.63×10(4)-19.55×10(4)), accounting for 24.66% (95%UI: 16.38%-33.12%) of total lung cancer deaths. The lung cancer death rate attributable to PM(2.5) increased with age, with the lowest among 25-29 age group (0.25/10(5), 95%UI: 0.17/10(5)-0.34/10(5)), the highest among ≥80 age group (90.70/10(5), 95%UI: 59.85/10(5)-122.20/10(5)). The lung cancer death rate attributable to PM(2.5) among males (14.84/10(5), 95%UI: 9.78/10(5)-19.93/10(5)) was higher than that in females (6.21/10(5), 95%UI: 4.07/10(5)-8.40/10(5)). The age-standardized death rates (ASDR) of lung cancer attributable to PM(2.5) among males and females in China were higher than the global average level. The attributable ASDR of lung cancer varied among provinces, highest in Shandong (13.51/10(5), 95%UI: 9.14/10(5)-18.20/10(5)) and lowest in Tibet (0.85/10(5), 95%UI: 0.44/10(5)-1.51/10(5)). Conclusion: In 2016, the lung cancer deaths attributable to ambient PM(2.5) exposure in China was heavy, and varied in different age groups, genders and provinces.

Abstract
In order to evaluate the intervention effect of the school-based salt reduction model, 28 primary schools were selected in Shandong Province in September 2014 and randomly divided into intervention group (1 361 students, 1 306 parents) and control group (1 364 students,1 340 parents). A series of "small hands and big hands" salt reduction intervention activities were conducted in intervention group for 8 months. After the intervention, the total awareness rate of salt reduction knowledge, the total holding rate of related beliefs and the total reporting rate of related behaviors were 70.65%, 80.30% and 67.03% among students, and 85.66%, 93.77% and 87.93% among parents, in the intervention group, which were higher than those in the control group (37.12%, 66.52% and 50.07% among students; 55.11%, 87.52% and 57.96% among parents) (all P values <0.05). The school-based salt reduction model is effective and feasible.

Abstract
Objective: To analyze deaths that attributable to high fasting plasma glucose and its impact on life expectancy among Chinese residents in 2013. Methods: Data from the Mortality Surveillance Programs in National Disease Surveillance Points System and the China Chronic Disease Surveillance (2013) were used. Death attributed to high fasting plasma glucose and its impact on the life expectancy of Chinese residents were estimated, based on the principle of population attributable fraction. Results: In 2013, the total number of deaths attributed to high fasting plasma glucose among aged ≥25 years old was 621 thousand, with 333 thousand males and 288 thousand females. Diseases related to the number of deaths caused by high fasting plasma glucose would include ischemic heart disease (212 thousand) as the most important one. Cerebrovascular disease appeared the 2(nd) place, with around 181 thousand cases and then followed by diabetes (145 thousand), chronic kidney disease (52 thousand) and tuberculosis (31 thousand). After removal of the effects on high blood glucose exposure, the life expectancy of Chinese residents in 2013 would have reached 76.5 years old, an average increase of 0.7 years, compared to the average life expectancy of all deaths, with men having an increase of 0.7 years and women of 0.8 years, respectively. Conclusions: High fasting plasma glucose appeared an important risk factor for mortality and life expectancy on the Chinese residents. Programs related to prevention and control of high fasting plasma glucose and related diseases should be strengthened.

Abstract
Objective: To investigate the role of ERK in the apoptosis of gastric cancer cells induced by miR-433. Methods: Lentivirus was used to transfect BGC-823 gastric cancer cell line to over-express miR-433. The blank control group (BGC-823), negative control group (BGC-823+ miR-433 negative control) and experimental group (miR-433+ miR-433, BGC-823-pMD18-T- miR-433)were set up. After treatment, the gastric cancer cell line BGC-823 was detected at 24 h, 48 h, and 72 h after culture, in vitro cell activity, cell apoptosis assays were performed by CCK-8 and Annexinv-FITC, respectively, to elucidate biological effects of miRNA-433, and After 72 h of culture, the ERK1/2 detected their protein expression were quantified by BCA method. Result: The growth activity of BGC-823+ miR-433 cells cultured in vitro was significantly lower than that of BGC-823 cells and BGC-823+ miR-433 negative control cells at 48 h and 72 h; BGC-823+ miR-433 cell apoptosis index was significantly increased at 24 h, 48 h, and 72 h; the expression of ERK1/2 was significantly lower than BGC-823 cells and BGC-823+ miR-433 negative contral after 72 h culture. There were no significant differences between BGC-823+ miR-433 negative control cells and BGC-823 cells. Conclusion: ERK plays an important role in the apoptosis of gastric cancer cells induced by miR-433.

Abstract
Objective: To analyze the deaths attributed to ambient air pollution in China between 2006 and 2016. Methods: The data were collected from the project of Global Burden of Disease in 2016 (GBD2016). The Data Integration Model for Air Quality were used to estimate exposure to particulate matter smaller than 2.5 μm in aerodynamic diameter (PM(2.5)). The attributable death number was calculated based on the calculation of population attributable fraction (PAF), and the results were compared by gender, diseases and provinces. An average world population age structure was adopted to calculate age-standardized rates. Results: In 2016, a total of 1 075 000 deaths attributed to ambient air pollution occurred in China, accounting for 11.1% of the total deaths, and 57.6% of the deaths attributed to ambient air pollution were due to ischemic heart disease and stroke. The death number among men was 1.7 times higher than that in women, Compared with 2006, the proportion of ambient air pollution related deaths in total deaths decreased by 6.8%; the age- standardized death rate attributed to ambient air pollution decreased by 26.5% and the decrease rate of lower respiratory infections (37.6%) and chronic obstructive pulmonary disease (42.1%) were greater than ischemic heart disease (5.3%). The age-standardized rate of death attributed to ambient air pollution decreased both in men and in women, but the decrease rate was higher in women (34.8%) than that in men (20.4%). The PAFs varied among provinces, it was highest in Tianjin (13.9%), lowest in Tibet (6.1%), and it was relatively higher in Beijing, Hebei, Shandong, Henan and the three provinces in the northeast and relatively lower in Hong Kong, Macao, Fujian and Hainan etc.. The age-standardized rate of death attributed to ambient air pollution was highest in Xinjiang (120.1/100 000) and lowest in Hong Kong (30.9/100 000), and it was relatively higher in Qinghai, Guizhou, Henan and relatively lower in Macao, Shanghai and Fujian, etc.. Compared with 2006, the PAFs of 17 provinces decreased, the decrease rate ranged from 4.1% to 16.8%, whereas the PAF of Jilin (5.0%) and Heilongjiang (8.1%) increased, and the PAFs of other 14 provinces showed no significant change. The attributable age-standardized death rate decreased in all provinces with the decrease rate ranging from 11.9% (Heilongjiang) to 43.2% (Fujian), and the decrease rate was relatively higher in Guangdong, Zhejiang and Guizhou, and lower in the three provinces in the northeast, Hubei and Hebei etc. Conclusions: In 2016, the disease burden attributable to PM(2.5) in China was heavy, but mitigated compared with 2006. The gender and area specific distributions of deaths attributed to ambient air pollution were observed.

Abstract
Objective: To investigate the prevalence of physical activity and its influencing factors in rural residents in Shanxi and Chongqing. Methods: In four counties (districts) of Shanxi and Chongqing, local residents aged ≥18 who lived there for more than one year and had no plan to migrate to other areas in 2 years were surveyed through face to face questionnaire interviews to collect the information about their daily physical activity time, sedentary time, related knowledge and attitude, and others. Results: The physical inactivity rate of the residents was 14.9%, and 88.7% of residents never took daily physical activity. The average sedentary time was (3.91±2.06) hours. The results of multivariate analysis showed that education level, per capita monthly income and activity degree were the factors influencing physical inactivity. Conclusion: The proportion of people who never took daily physical activity in the survey area was higher than the average level in rural areas in China, so measures should be taken to improve the overall rate of physical activity. For people who have exercise willingness, but have no practice, and those who have already increased their physical activities, targeted guidance is needed on the basis of strengthened health education.

Abstract
Objective: To examine the effects and associated factors of the China Motivational Healthy Walking Program among occupational population. Methods: The 2016 China Motivational Healthy Walking Program recruited 29 224 participants from 139 demonstration areas for comprehensive prevention and control of chronic and non-communicable disease at national level and 70 at provincial level. Intervention on walking was carried out by adopting group and individual motivating measures. Walking steps were recorded by electronic pedometer. We used percent of days achieving 10 000 steps (P10 000), percent of days fulfilling continuous walking (PCW), and proportion of valid walking (PVW) steps to reflect walking quantity, pattern and quality of participants. Motivation intensity was measured by summing up scores of each motivating activity. Questionnaire-based online survey collected information about demographic characteristics, lifestyle risk factors and chronic diseases. This study finally included 12 368 individuals in the analysis. Multilevel logistic regression model was used to assess the effect of group and individual motivating measures on walking activity and corresponding associated factors. Results: Age of the study sample was (41.2±8.99) years, and 58.17% (7 194) of them were female. After 100-day intervention, the P10 000, PCW and PVW of all participants were 93.89%±14.42%,92.01%±15.97% and 81.00%±7.45%, respectively. The mean P10 000 and PCW increased with rising group-motivated scores, self-motivated scores and individual-activity scores (P<0.001 for all). The mean PVW decreased with both higher group-motivated scores and self-motivated scores (both P<0.05), and varied little among groups with different level individual-activity scores (P=0.525). According to the results from the multilevel model, those who had greater group-motivated scores and self-motivated scores tended to have more likelihood of high-level of P10 000 and PCW. Age, sex, smoking status, education attainment and alcohol drinking were associated with P10 000 and PCW (P<0.05 for all). Conclusion: The Motivational Healthy Walking Program had positive effect on promoting healthy walking among occupational population. Group-motivated and self-motivated activities were associated with healthy walking.

Abstract
Objective: To study the association between blood pressure related dietary pattern and cognitive impairment in the elderly. Methods: In 2015, all participants who were aged ≥60 and participated in the Nutrition and Chronic disease family cohort were involved in the study. Information on demographic variables, lifestyle and health status was collected. Cognitive performance was assessed by the Mini Mental State Evaluation (MMSE) scale. Blood pressure, height and weight were measured by trained medical personnel and fasting venous blood samples were collected for testing on serum level of triglycerides and total cholesterol. Both SBP and DBP were used as response variables when dietary patterns were identified by reduced rank regression method. Logistic regression models were fit to explore the associations of scores on blood pressure-related dietary pattern and cognitive impairment. Results: Two blood related dietary patterns were identified. The first one was characterized by high consumption of vegetables and less meat, eggs and dessert (Pattern 1), while the second one was with high consumption of meat, soy products, wine and fried foods and less intake of dairy (Pattern 2). Data showed that the Pattern 1 was associated with the risk of cognitive impairment. Comparing with the lowest quartile of score of this dietary pattern, the risk of cognitive impairment in the highest quartile group showed a significant (P<0.01) increase, with OR=1.94 (1.21-3.11) and showing significant (P=0.002) linear trend. However, no significant association was observed (P>0.05) with cognitive impairment in the second dietary pattern. Conclusion: Blood pressure-related dietary pattern was positively associated with cognitive impairment.

Abstract
Objective: To analyze the rates on prevalence, awareness, status on treatment and control of type 2 diabetes mellitus among Chinese premenopausal women aged 18-49, in 2013. Methods: Data on China Chronic and Non-Communicable Disease Surveillance in year 2013 was used for analysis. Source of data covered 302 surveillance points which were selected by Multi-stage cluster random sampling method that including 176 534 adults over 18 years of age, with 46 674 premenopausal women aged 18-49. Plasma glucose and hemoglobin A1c levels were determined after a 10-hour overnight fast for all the participants, before a 2-hour oral glucose tolerance test was conducted among participants without a self-reported history of diagnosed diabetes. Diabetes was defined according to the 1999 WHO diagnostic criteria-fasting blood glucose level as ≥7.0 mmol/L and/or 2 hours oral glucose tolerance test (OGTT-2 h) level as ≥11.1 mmol/L. After being weighed, according to complex sampling scheme and post-stratification, the sample was used to estimate the rates of prevalence, awareness, treatment and control of type 2 diabetes mellitus by age, education, urban and rural areas, and geographic locations. Results: The overall prevalence of type 2 diabetes mellitus was 5.6% among the Chinese premenopausal women aged 18-49. No statistical difference on the prevalence rates (5.7% and 5.4%, respectively) was seen, between participants from the rural or the urban areas. Prevalence rates in the eastern, central or western geographic areas were 5.8%, 6.2% and 4.4% respectively. The rates of awareness, treatment and control of diabetes appeared as 29.3%, 27.9% and 29.4% in childbearing women aged 18-49. The rate of treatment was 95.4% among those who knew their diabetic situation in childbearing women aged 18-49 years. The control rate of diabetes was 38.9% among those who had taken measures to control glucose, in 18-49-year-old childbearing women. The rate of awareness on diabetes in childbearing women aged 18-49 years in urban areas was higher than that in the rural areas. There were significantly statistical differences on the treatment rates among groups of different education levels but not in the trend test. Conclusion: The prevalence of type 2 diabetes mellitus in childbearing women aged 18-49 appeared high, but with low rates on awareness, treatment and control. However, statistical difference was seen on awareness, between urban and rural areas.

Abstract
Objective: To analyze the rate of prevalence, awareness, treatment and control of hypertension among women at reproductive age (18-49 years old) in China in 2013. Methods: The analysis used data obtained from the China Chronic and non-communicable disease surveillance in 2013.The surveillance included 176 534 adults aging ≥18 years old, who were selected from 302 surveillance points by multi-stage cluster random sampling method. A total of 46 674 women at reproductive age (18-49 years old) were investigated. Blood pressures were measured by electronic blood pressure monitor. After being weighted according to complex sampling scheme and post-stratification, the rate of prevalence, awareness, treatment and control of hypertension were compared by different characteristics such as age, education, urban and rural areas, and geographic locations. Results: The prevalence of hypertension among women at reproductive age (18-49 years old) in China in 2013 was 13.5%. The rate in the rural areas was higher than that in urban areas (χ(2)=46.23, P<0.05), which were 14.5% and 12.3%, respectively. The prevalence in eastern, central and western geographic locations were separately 13.9%, 13.2% and 13.1%, there was no statistical difference (χ(2)=0.56, P>0.05). The hypertension prevalence in all age groups (18-24, 25-29, 30-34, 35-39, 40-44, 45-49 years old) were 6.6%, 9.2%, 9.6%, 12.0%, 17.9% and 28.3%, respectively. The prevalence of hypertension showed a rising trend with age increasing (t=12.32, P<0.05). The awareness, treatment and control rates of hypertension were separately 25.8%, 22.7% and 7.4% in women at reproductive age (18-49 years old), which were 31.6%, 28.2% and 9.4%, respectively in urban areas; and 21.3%, 18.5% and 5.9%, respectively in rural areas. The rates in urban areas were all higher than those in rural areas (chi square were separately 18.98, 21.31, and 6.80, P values <0.05). The treatment rate of hypertension was 86.8% among who had been aware of hypertension, and the treatment rate of hypertension was 31.8% among who received control of hypertension. The treatment rate among who had been aware of hypertension in eastern, central and western locations were 89.3%, 88.3% and 79.5%, respectively. The control rates in eastern, central and western locations were 8.5%, 8.1% and 4.7%, respectively. The treatment rate among who had been aware of hypertension and control rate in the eastern and central geographic locations was higher than that in western locations (chi square were separately 10.05 and 7.25, P values <0.05). Conclusion: The prevalence of hypertension in women at reproductive age (18-49 years old) was comparatively high, and the rates of awareness, treatment and control were low. The differences showed statistical significance between urban and rural areas.

Abstract
Objective: To analyze the contrast echocardiography for detecting right to left shunt in adults with patent foramen ovale(PFO), and study the relationship between PFO and cryptogenic stroke. Methods: Clinical data of forty-six adults patients with PFO diagnosed by transesophageal echocardiography(TEE)from March, 2012 to March, 2017 were retrospectively collected, and the patients were divided to 3 groups according to the direction and brightness of the color Doppler shunts: obvious left-to-right shunt (OLRS, group A), weak left-to-right shunt(WLRS, group B), bi-directional shunt(BDS, group C). A right-to-left shunt (RLS) scale was calculated using the method of 10 ml hand-operated saline for contrast echocardiography. Results: There were seventeen cases in group A, four cases (23.5%) showed RLS at level 1, and thirteen cases (76.5%) showed no RLS; there were twenty cases in group B, and all cases (100%) showed RLS, with five cases (25%) at level 1 and fifteen cases (75%) at level 2-3; there were nine cases in group C, and all cases (100%) showed RLS, with two cases (22.2%) at level 1 and seven cases (77.8%) at level 2-3. Anteroposterior diameter of left atrium of patients with no RLS (4.8 cm±0.6 cm) was significantly larger than that of patients with RLS in contrast echocardiography (3.6 cm±0.5 cm)(P=0.000). Conclusions: OLRS of adults with patent foramen ovale and with larger left atrium have less RLS than WLRS and DLRS with normal left atrium in contrast echocardiography.The possibility of paradoxical embolism in WLRS and DLRS is higher than that in OLRS, which should be taken seriously in clinical practice.

Abstract
OBJECTIVES To observe and analyze the performance of forensic science in the cases of suxa- methonium chloride poisoning, and to improve the identification of suxamethonium chloride poisoning. METHODS Fifty-four cases of suxamethonium chloride poisoning were collected. The rules of determination of suxamethonium chloride poisoning were observed by the retrospective analysis of pathological and toxicological changes as well as case features. RESULTS The pathological features of suxamethonium chloride poisoning were similar to the general changes of sudden death, which mainly included acute pulmonary congestion and edema, and partly showed myocardial disarray and fracture. Suxamethonium chloride could be detected in the heart blood of all cases and in skin tissue of part cases. CONCLUSIONS Suxa-methonium chloride poisoning has the characteristics with fast death and covert means, which are difficult to rescue and easily miss inspection. For the cases of sudden death or suspicious death, determination of suxamethonium chloride should be taken as a routine detection index to prevent missing inspection.

Abstract
Objective: To analyze the burden of disease attributed to high fasting plasma glucose(FPG)in China in 1990 and 2013. Methods: The analysis used data obtained from the 2013 Global Burden of Diseases Study and examined deaths, death rate, disability-adjusted life years(DALY), years lived with disability(YLD)and years of life lost(YLL)attributed to high FPG in 1990 and 2013 in China(not including Taiwan, China). An average world population age-structure for the period 2000- 2025 was adopted to calculate age-standardized rates. Results: In 2013, the number of deaths attributed to high FPG in China increased to 621.9 thousand from 320.3 thousand in 1990. From 1990- 2013, the age-standardized death rate attributable to high FPG increased from 45.69/100 000 to 48.64/100 000. DALYs caused by high FPG increased to 20.389 1 million in 2013 from 10.648 3 million in 1990. In 2013, high FPG caused 8.751 5 million YLD and 11.637 6 million YLL, and the percentage of YLL in DALY decreased to 57.1% in 2013 from 68.7% in 1990. Compared with 1990, the age-standardized DALY rate attributed to high FPG increased by 10.81%. In 2013, the top three provinces with the highest burden of disease attributed to high FPG were Xinjiang, Jilin and Liaoning provinces, with standardized death rates of 83.38, 74.01 and 68.64/100 000, respectively, and the standardized DALY rate was 2 217.96, 2 001.84 and 1 837.79/100 000 in the three provinces, respectively. Conclusion: Compared with 1990, the burden of disease attributed to high FPG in 2013 increased substantially in China, in particular the burden of attributed YLD. However, the burden of YLL attributed to high FPG has decreased modestly. The burden of disease caused by high FPG shows variation among different provinces in China.

Abstract
Objective: To establish an animal model of hard metal lung disease (HMLD) in rats, and to screen the indications for diagnosis of HMLD. Methods: The rats were randomly divided into 5 groups, each group included 8 rats: saline group, pure cobalt group, pure tungsten carbide group, silica group and hard metal (HM) group. 10 mg subjects were administered in each group by using the pulmonary endotracheal tube. After 8 week, the lung CT scan and lung tissue pathology were observed, the serum and bronchoalveolar lavage fluid (BALF) were collected for KL-6, TGF-beta1 and TGF-beta2. Results: The lung tissue structure of HM group was destroyed, a large number of nuclear giant cells and epithelial like cells appeared in the stroma, and uncommon CT scan images appeared in the lung. KL-6, TGF-beta1, TGF-beta2 expression in each group was not the same, the difference was statistically significant (P<0.05) . The expression of KL-6 and TGF-beta1 in serum was not identical in all the groups, the difference was statistically significant (P<0.05) . The expression of TGF-beta2 had no significant difference between the groups (P>0.05) . Conclusion: Rats can be successfully established HMLD model, rats in vivo lung CT scan images appear abnormal, which are provided with assistant diagnostic value for HMLD. The expression of KL-6 and TGF-beta2 in serum and BALF on HMLD rats are not highly specific, and TGF-beta1 has reference value in the rat HMLD auxiliary diagnosis.

Abstract
In pursuit of lightweighting of automobiles and low emission of transportation, the efforts to develop high-strength, heat-resistant and fatigue-resistant Al alloys and/or composites have been ongoing. Here we report a novel Al matrix composite with ultrahigh strength reinforced by a three dimensional network of nano-AlN particles for the first time. The in-situ synthesized AlN particles are connected by twinning bonding chains and built up a three dimensional network strengthening Al matrix enormously like the skeleton to human body. The composite containing 16.4wt.% AlN particles shows excellent properties: the ultimate tensile strengths can be up to 518MPa at room temperature and 190MPa at 350 °C. This peculiar performance results from the novel spatial distribution of nano-scale AlN particles. Our findings in this work would help to develop a potential candidate for high-performance heat resistance light-metal based materials.

Abstract
Objective: To analyze the burden of disease attributed to high total cholesterol(TC)in 2013 in China. Methods: We used data from the 2013 Global Burden of Disease Study. The population attributable fraction was calculated to estimate the deaths and disability-adjusted life years(DALY)attributed to high TC. Disease burden was compared by age, gender, diseases and province(not including Taiwan, China). An average world population age structure for the period 2000- 2025 was adopted to calculate age-standardized rates. Results: In 2013, high TC caused 298 952 deaths in China, accounting for 3.3% of total deaths, and caused 6 332 thousand DALYs. DALYs attributed to high TC were highest among the 50-69 years age group(3 165 thousand person years), accounting for 50.0% of the total attributed DALYs. The DALY rate in the ≥70 years age group was 2 053.3/100 000, which was 10.3 times that of 15-49 age group(198.6/100 000). DALYs among men were 4 431 thousand person years, which was 2.3 times higher than in women(1 900 thousand person years), and the age-standardized DALY rate among men was 590.6/100 000, which was 2.3 times higher than in women(257.1/100 000). DALYs attributed to high TC were mainly caused by ischemic heart disease(IHD; 5 572 thousand person years), accounting for 88.0% of the total attributed DALYs. Deaths and DALYs attributed to high TC were highest in Shandong(31 002 and 628 thousand person years for deaths and DALYs, respectively), Henan(27 398 deaths and 587 thousand person years, respectively), Hebei(25 744 deaths and 589 thousand person years, respectively), accounting for 28.1% of total attributed deaths and 28.5% of total attributed DALYs. The number of deaths and DALY were lowest in Macao(75 deaths and 1 thousand person years, respectively)and Tibet(385 deaths and 10 thousand person years, respectively). The age standardized DALY rates were highest in Beijing(794.8/100 000), Hebei(732.7/100 000), and Jilin(709.1/100 000), and lowest in Shanghai(151.4/100 000), Zhejiang(168.1/100 000), and Hong Kong(182.0/100 000). Conclusion: The burden of disease attributed to high TC in 2013 in China was mainly the result of the IHD it causes, with greater influence among males and those aged ≥50 years, and variation among provinces.

Abstract
OBJECTIVE To develop a method for the determination of 11 perfluorosulfonate and perfluorocarboxylate precursors in eggs using ultra-high performance liquid chromatography-tandem quadruple mass spectrometry (UPLC-MS/MS). METHODS The target compounds of egg were extracted with 100 mmol/L NaOH-acetonitrile /water(90∶10, V/V) by ultrasonic. Then the extract was purified by solid phase extraction (Waters Oasis(@) WAX 6cc) and then eluted with 9% NH4OH in methanol. The target compounds were separated on a Waters ACQUITY(TM) BEH (18)C column (50 mm × 2.1 mm, 1.7 μm) and detected by negative electrospray ionization (ESI(-)) mass spectrometry in multiple reaction monitoring mode (MRM). All compounds were quantified with internal standards. The accuracy, precision and the limits of detection and quantification of the method were evaluated. Then we detected 7 different egg samples from the market. RESULTS The average recoveries for the eleven precursors at 3 levels were 74.09%-116.82% and the relative standard deviations were 2.37%-13.62%. The limits of detection (LOD) of the method were in the range of 0.06-1.50 pg/g (wet weight) and the limits of quantification (LOQ) were in the range of 0.15-3.00 pg/g (wet weight). And 5 target compounds were detected in the 7 market samples. 6:2 fluorotelomer sulfonate (6:2 FTS) was detected in all of samples with the concentrations of 1.67-3.11 pg/g. 6:2 fluorotelomer unsaturated acid (FHUEA) and 6:2 disubstituted polyfluoroalkyl phosphate ester (6:2 diPAP) were detected in 6 samples and the concentrations were<LOD-5.11 pg/g and 3.78-9.16 pg/g, respectively. And the concentrations of 8:2 fluorotelomer sulfonate (8:2 FTS) and N-methyl perfluorooctane sulfonamidoacetic acid (N-Me FOSAA) founded in the same sample were 105.78, and 4.95 pg/g, respectively. CONCLUSION This method was simple, rapid, and suitable for determination of perfluorosulfonate and perfluorocarboxylate precursors in eggs with high accuracy and sensitivity. It could also be applied to human burden studies of these precursors.

Abstract
OBJECTIVE To evaluate the diagnostic performance of bi-exponential modeling of intravoxel incoherent motion (IVIM) imaging for laryngeal and hypopharyngeal carcinoma. METHODS A total of 32 patients with pathologically proven laryngeal and hypopharyngeal squamous cell carcinoma were included in this study from November 2014 to August 2015.All patients underwent IVIM-DWI by using twelve b values (0, 10, 20, 30, 50, 70, 100, 150, 200, 400, 800 and 1 000 s/mm(2)). Using the IVIM approach, D, D(*) and f values were extracted using a bi-exponential fit.These quantitative parameters of primary carcinoma and normal pharyngeal tissue were compared.Statistical methods were used to assess differences between the tumor and normal pharyngeal tissue. RESULTS There were no significant differences of D (P=0.903) and f (P=0.223) values observed among laryngeal carcinoma and hypopharyngeal carcinoma, and D(*) value was significantly different among the two groups (P=0.028). The values of D, D(*,) and f for primary carcinoma were (0.84±0.22)×10(-3) mm(2)/s, (65.71±19.66)×10(-3) mm(2)/s, and 45%±14%, respectively; for normal pharyngeal tissue were (1.48±1.04)×10(-3) mm(2)/s, (37.85±14.04)×10(-3) mm(2)/s, and 36%±12%, respectively (P=0.001, 0.000, and 0.006, respectively). Setting D value 0.949×10(-3) mm(2)/s was threshold to distinguish abnormal and normal tissues, the sensitivity, specificity and accuracy were 91.2%, 88.2% and 92.5%, respectively.There was no statistically significant difference of D and f values(both P>0.05)in different pathological grades of primary carcinoma, and there was statistically significant difference in D(*) values found among the different pathological grades of primary carcinoma (P=0.001). There were statistically significant differences in D(*) values between the well differentiated group and the other two group (both P<0.05), and there was no statistically significant difference between the moderately differentiated group and poorly differentiated group (P>0.05). CONCLUSION IVIM parameters can reflect the difference between laryngeal and hypopharyngeal carcinoma and normal pharyngeal tissue, and the D value has the best diagnostic performance.D(*) value in different pathological grades of laryngeal and hypopharyngeal squamous cell carcinoma is distinct, and it could reflect the pathological grade of tumor to some extent.
