Abstract
Objective: To investigate the clinical significance of detection of myositis-specific antibodies (MSAs) and myositis-associated antibodies (MAAs) in patients with connective tissue disease-associated interstitial lung diseases (CTD-ILD). Methods: Serum samples of 120 patients with CTD-ILD admitted to the Department of Respiratory, Affiliated Drum Tower Hospital of Nanjing University Medical College from December 2016 to April 2018 were collected for analysis. The patients included 45 with polymyositis/dermatomyositis (PM/DM), 36 with Sjogren's syndrome (SS) and 39 with undifferentiated connective tissue disease (UCTD). There were 37 males and 83 females with an average age of (56±11) years. Thirty-two patients with non-CTD-ILD, 10 males and 22 females with an average age of (42±17) years, were enrolled as the control group. Euroline Autoimmune Inflammatory Myopathies 16 Ag kit was used for detecting MSAs and MAAs, and the positive rates of serum MSAs and MAAs were calculated. The antibody distribution and clinical characteristics of different groups were analyzed and compared. Results: Eighty-nine of the 120 patients with CTD-ILD were positive for MSA and/or MAA (74.2%), and the detection rates of MSAs and MAAs were 52.5% (63/120) and 61.7% (74/120) respectively. No myositis antibody was detected in the non-CTD-ILD group. The detection rates of MSAs in PM/DM-ILD group, SS-ILD group and UCTD-ILD group were 75.6% (34/45), 33.3%(12/36) and 43.6%(17/39) respectively. The total detection rate of MSAs in PM/DM group was significantly higher than that in SS group and UCTD group (χ(2)=14.53, 8.95, 0.01). The anti-ARS was the most frequent (50/120, 41.7%). The positive rates of MAAs in the three groups were 64.4%(29/45), 77.8%(28/36), 43.6%(17/39) respectively, and anti-Ro-52 accounted for 60%(72/120), and were highly correlated with MSAs such as anti-Jo-1 antibodies. Conclusion: Myositis antibody profiling should be performed in patients with ILD who were negative for conventional autoimmune antibody testing and had no CTD. In patients with SS-ILD and UCTD-ILD, the myositis antibody spectrum could detect the presence of myositis-specific antibodies and myositis-related antibodies in some patients, and its role in clinical diagnosis and treatment needed further observation.

Abstract
OBJECTIVE Tacrolimus prolonged-release(PR) formulation is a new once-daily formulation of the calcineurin inhibitor tacrolimus, which is currently used in adult liver or kidney transplant patients,and is also gradually widely used in children with nephrotic syndrome.The present study was undertaken to preliminarily investigate the pharmacokinetic characteristics of tacrolimus PR in pediatric nephrotic syndrome recipients. METHODS This single-center open-label prospective study was performed in pediatric nephrotic syndrome recipients. Pharmacokinetic samples were collected from eight pediatric subjects with nephrotic syndrome from Department of Pediatric Nephrology in Peking University First Hospital between June and August 2011. They followed administration of single oral doses of tacrolimus PR formulation at 0.02 mg/kg (n=2), 0.05 mg/kg (n=2) and 0.10 mg/kg (n=4). Blood samples were taken before the dose and 1, 2, 4, 6, 8, 10, 12 and 24 h after drug intake. No other medicines or interacting food or drinks were taken during the study period. Blood concentrations were measured using an enzyme multiplied immunoassay technique. Pharmacokinetic analysis was performed using WinNolin Phoenix software Version 6.0(Pharsight, Cary, NC,USA). RESULTS The pharmacokinetic data were best described by a non-compartment model. Pharmacokinetic parameters of tacrolimus PR formulation in the 3 ascending doses groups (0.02 mg/kg,0.05 mg/kg and 0.10 mg/kg) were as follows: the maximum drug concentrations (Cmax/D) were (1.7±1.0) μg/L, (3.1±1.9) μg/L, (8.0±3.5) μg/L, respectively; Areas under the drug concentration-time curve(AUC0-∞/D) were (47.2±47.1) h×μg/L, (84.0±13.1) h×μg/L, (175.6±107.1) h×μg/L, respectively; Oral clearance rates were (0.8±0.9) L/(h×kg), (0.4±0.1) L/(h×kg), (1.9±1.3) L/(h×kg), respectively; Body weight normalized distribution volumes were (7.0±3.4) L/kg, (12.4±8.4) L/kg and (73.6±68.6) L/kg, respectively. Both mean Cmax normalized level for the administered dose(Cmax/D) and mean AUC0-∞ normalized level for the administered dose (AUC0-∞/D) were higher in the 0.05 mg/kg dosage group than in the 0.02 and 0.10 mg/kg dosage group. There were two peaks in the drug concentrations in every dose group;a primary peak appeared at the end of about 2 h followed by a small secondary peak at h 12, which was more noticeable in the 0.10 mg/kg dose group than in the two lower dosages. CONCLUSION The pharmacokinetic characteristics of tacrolimus PR formulation were initially explored in pediatric patients with nephritic syndrome. The data presented form a basis for subsequent larger scale studies on pharmacokinetics of tacrolimus PR formulation in nephritic syndrome children.

Abstract
Organophosphate flame retardants (OPFRs), which have both great properties of flame retardation and plasticization, are currently widely used as additive flame retardants. Due to the restriction and phase-out of brominated flame retardants (BFRs), the market demand for OPFRs as excellent alternatives of BFRs has been rapid increasing. OPFRs can be slowly released into the environment during production and application. Some OPFRs might be persistent in the environment. As a result, OPFRs have been detected in various matrices in the environment and are expected to accumulate in human body through various pathways. OPFRs may cause adverse effects to human health as some of them have been identified as neurotoxicants, reproductive toxicants and potential carcinogens. The article summarized the occurrence and patterns of OPFRs in various environmental matrices such as air, dust, water, food and so on, and in human specimens, estimates the exposure status through different pathways and body burdens of OPFRs. The expected hotspots of OPFRs were also discussed in the future.

Abstract
This work presents a physicochemical study of frozen amorphous methane (at 16 K) under bombardment by medium-mass ions (15.7 MeV 16O5+) with implications for icy bodies in the outer Solar System exposed to the action of cosmic rays and energetic particles. The experiment was performed at the Grand Accélérateur National d'Ions Lourds (GANIL) located in Caen, France. The results demonstrate that irradiation of CH4-containing ices by swift medium mass ions with delivered energy covering both stopping power regimes until its implantation on ice (i.e. electronic and nuclear) leads to the production of many hydrocarbons, such as C2H2, C2H4, C2H6, and C3H8 (the most abundant daughter species produced). Values for the effective dissociation cross section of CH4 and the average value for the effective formation cross-sections of its daughter species were about 10-14 cm2 and 10-15 cm2, respectively. The half-life of methane ice in the presence of swift medium mass ions extrapolated to some outer Solar System environments is estimated to be around 106 years. The measured sputtering yield of methane due to incoming swift ions was about 7.30 × 105 molecules per impact. Such parameters can be used as models to estimate the amount of CH4 and other molecular species desorbed from the icy surfaces that are constantly being incorporated to the gaseous atmosphere in the vicinity of these outer Solar System bodies due to the presence of energetic particles and cosmic rays.

Abstract
Seed length and seed width are an important factor to the soybean yield. So the quantitative trait loci (QTL) location for seed length and seed width could assistant the breeding of soybean. In this study, the QTL underlying seed length and seed width were studied. A recombinant inbred line population of soybeans derived from a cross between the American semi-draft cultivars Charleston and Dongnong 594 were used in 7 environments. The quantitative trait loci underlying seed length, seed width, and seed length/seed width were analyzed by the method of composite interval mapping. Then, the epistatic effects and the QTL-environment (QE) interaction effects were also analyzed. Some valuable QTL sites found had great effect to the seed trait. Results showed that 7 QTLs underlying seed length were identified mainly on linkage groups D1a, C2, B1, A1, G, and A2. For the seed width, 7 QTLs were identified on linkage groups D1a and O. Two QTLs of seed length/seed width were identified on linkage groups D1b and C2. No QE interaction was found for QTLs of seed length and seed width in 7 environments. QTLs of seed length/seed width on linkage groups A1 and I had a QE interaction in 7 environments. Seven pairs of QTLs were identified that affected additive x additive epistatic effect of seed length, seed width, and seed length/seed width, which occurred among 8 linkage groups. These results supply a good foundation for molecular assistant breeding for soybean seed trait.

Abstract
BACKGROUND To investigate the distribution of HBV genotypes in Guizhou and study the relationship between the genotype and the progression of liver disease. METHOD Totally 693 patients with chronic HBV infection, from 4 areas of Guizhou, including 292 asymptomatic HBV carriers (ASC), 276 cases with chronic hepatitis (CH), 76 liver cirrhosis (LC), 49 hepatocellular carcinoma (HCC) were examined. The HBV genotype was determined by restriction fragment length polymorphism analysis and the relationship between HBV genotype and the progression of liver disease was studied by multifactor analysis such as HBsAg positivity, HBV DNA load and ALT level. RESULTS Of the 693 patients, 6 (0.87%), 449 (64.79%), 233 (33.62%), and 5 (0.72%) belonged to genotype A, B, C and D, respectively. There was a statistically siganificant difference in the distribution of genotype B among Kaili (96.4%), Zunye (78.79%), Duyun (76.19%) and Guiyang (53.66%) areas (P less than 0.01). Genotype C was more prevalent in Guiyang than in other three areas (45.68% vs. 23.8%, 45.68% vs. 13.13%, 45.68% vs. 3.96%, P less than 0.01, respectively). There were also statistically significant difference in distribution of genotype B and C in various stages of liver disease (P less than 0.01). Genotype B showed a decreasing trend from ASC, CH, LC to HCC and genotype C was more frequent in patients with CH (45.92%) than in those with ASC (20.6%), LC (17.17%) and HCC (16.31%). The ALT levels and the mean ages were significantly higher and older in patients with genotype C than those in genotype B. The HBeAg positivity was significantly lower in genotype C than that in genotype B (48.07% vs 61.90%, P less than 0.01). CONCLUSION Genotype A, B, C and D exist in Guizhou. Genotype B predominates and genotype C was the second common. The geographic distribution of genotype B and C are different in some areas of Guizhou. Compared with genotype B, genotype C is associated with the development of more severe liver damage.

Abstract
The fractional Fourier transform (FRFT) has been used for many years, and it is useful in many applications. Most applications of the FRFT are based on the design of fractional filters (such as removal of chirp noise and the fractional Hilbert transform) or on fractional correlation (such as scaled space-variant pattern recognition). In this study we introduce several types of simplified fractional Fourier transform (SFRFT). Such transforms are all special cases of a linear canonical transform (an affine Fourier transform or an ABCD transform). They have the same capabilities as the original FRFT for design of fractional filters or for fractional correlation. But they are simpler than the original FRFT in terms of digital computation, optical implementation, implementation of gradient-index media, and implementation of radar systems. Our goal is to search for the simplest transform that has the same capabilities as the original FRFT. Thus we discuss not only the formulas and properties of the SFRFT's but also their implementation. Although these SFRFT's usually have no additivity properties, they are useful for the practical applications. They have great potential for replacing the original FRFT's in many applications.

Abstract
Hepatitis B virus (HBV) DNA integration was studied in 24 hepatocellular carcinoma (HCC) tissues obtained at operations or autopsies. In 11 cases whose sera were positive for hepatitis B virus surface antigen (HBsAg), HBV DNA integration was demonstrated by Southern blot analysis. Only one of 6 cases whose sera were positive for hepatitis B surface antibody (HBsAb) but negative for HBsAg revealed the integration and the other 5 cases revealed no HBV DNA integration. HBV DNA amplification was noted in 4 of these 6 cases in which HBV DNA integration was found when compared with the adjacent liver tissues. The integration pattern of HBV DNA was different in one case between primary HCC tissue and a metastasized lymph node. It is suggested that HBV DNA amplification is not directly related to the development of HCC and that there are polyclonal tumor cells which have different patterns of virus genome integrations.
