Abstract
OBJECTIVE Diabetic nephropathy (DN) is one of the most representative diabetic microangiopathy complications. So far, there have been no satisfactory therapeutic strategies, and the injection of stem cells provides a target for DN therapy. PATIENTS AND METHODS Urine-derived stem cells (USCs) were obtained from 9 healthy men. 24 mice were randomly and equally divided into control group, DN model group, DN+hUSC group (treated with USCs for 3 times). Hematoxylin-eosin (HE) and Masson staining were used to detect histological changes of kidney injury. Creatinine and blood urea nitrogen (BUN) were measured to assess renal function. Besides, myofibroblast accumulation, macrophage infiltration, cell proliferation, and oxidative stress were detected by immunohistochemical analysis. RESULTS Compared with DN model group, DN+hUSC group showed lower function loss, cell infiltration, and oxidative stress, as well as less renal fibrosis, histological damage, and cell proliferation. CONCLUSIONS USC can alleviate inflammation and oxidative stress, reduce renal interstitial fibrosis, improve renal tissue structure and protect renal function through paracrine effect.

Abstract
PURPOSE To assess the longitudinal associations between maternal total bile acid (TBA) levels during early mid-pregnancy and the subsequent risk of gestational diabetes mellitus (GDM). METHODS In a prospective cohort study, pregnant women who were enrolled prior to gestational week 16 were followed until delivery. TBA levels were tested during weeks 14-18 of gestation. Using logistic regression, we analyzed the associations between quartiles of TBA and GDM based on a 75-g oral glucose tolerance test (OGTT) at 24-28 gestational weeks. RESULTS The GDM rate was 7.9% (114/1441). The mean TBA level was higher in women with GDM than in those without GDM (2.1 ± 2.0 vs 1.5 ± 1.0 µmol/L, P = 0.000). The highest TBA level quartile (2.1-10.7 µmol/L) had a 1.78-fold (95% CI 1.01, 3.14) increased risk of GDM compared with that of the lowest quartile (0.0-0.8 µmol/L) after adjusting for pre-pregnancy body mass index (BMI), gestational, age at TBA test and other confounders. High TBA levels were involved in the fasting glucose level rather than that at 1 h and 2 h after OGTT in all participants. CONCLUSIONS Pregnant women with higher serum TBA levels during early mid-pregnancy have a higher risk of developing GDM. TBA may be a new risk factor for GDM.

Abstract
During a harvest period, a set of field samples, including ambient air (gaseous and particulate phases), dust fall, surface soil and peel-surrounding soil, and yellow carrot tissues (leaf, peel, and core), were collected in a vegetable bases near a large coking manufacturer in Shanxi Province, Northern China. Based on the determinations of the concentrations and compositions of 15 USEPA priority polycyclic aromatic hydrocarbons (PAHs), the statistical results determined by a factor analysis (FA), combined with the isomeric ratios of paired species and the local emission inventory, indicated that coal combustion and vehicular exhaust served as the main emission sources of PAHs in the local environment and in yellow carrot tissues and that the coking industry was a secondary source. In terms of the transport pathways of PAHs in the surrounding media and yellow carrot tissues, the simulation results of a structural equation model (SEM) showed that the PAHs in ambient air were closely associated with those in dust fall, and these in turn had a positive correlation with the PAHs in surface soil, due to air-soil exchange. Furthermore, the PAHs in yellow carrot leaf were mainly derived from those in dust fall via leaf surface absorption, while peel uptake played a dominant role in the accumulation of PAHs in the edible core of yellow carrot. This was different from the case of cabbage, which was characterized by the prevailing contribution from leaf surface absorption. The current study supplied additional evidence to explore the transport pathways of PAHs from environmental media to tissues of different vegetables (leafy vegetables and root vegetables). CAPSULE: A combination of structural equation modeling with factor analysis was employed to quantitatively identify the dominant transport pathways of PAHs among multiple surrounding media and the different tissues of yellow carrot.

Abstract
Atmospheric PM10 (particulate matter with aerodynamic diameter <10 μm) samples were collected in the cities along the Bohai Sea Rim during heating and non-heating periods, and ionic per- and polyfluoroalkyl species (PFASs) in the PM10 were measured. The total concentration of ionic PFASs ranged from 21.8 to 87.0 pg/m3, and the mean concentration of ionic PFASs during the day (42.6 pg/m3) was slightly higher than that at night (35.1 pg/m3). Generally, diurnal variations in the levels of ionic PFASs were consistent with those in the PM10 concentrations. Perfluorooctanoic acid (PFOA, 23.5-33.7%), perfluoropentanoic acid (PFPeA, 28.3-39.9%) and perfluorobutyric acid (PFBA, 17.1-20.1%) accounted for the dominant compositional contributions. Significant positive correlations (p < 0.05) between the main components of PFASs and O3 implied that oxidative degradation (O3 served as the main oxidant) in the period of non-heating may affect the short-chain PFASs. The clustering analysis of a 72-h backward trajectory indicated that cross-provincial transport contributed to ionic PFASs at the sampling sites. Compared with ingestion via daily diet, the inhalation of PM10 exhibited an insignificant contribution to the estimated average daily intakes (ADIs) of PFASs by different age groups. In addition, the calculated hazard ratios (HRs) for the non-cancer respiratory risk, based on the air concentrations of PFOA and perfluorooctane sulfonate (PFOS), also manifested lower non-cancer risk through inhalation exposure. CAPSULE: The effects of heating and non-heating activity and diurnal variation on the concentrations of PFASs, dominated by PFOA, PFPeA, and PFBA in PM10, were determined, and atmospheric trans-provincial input served as an important source.

Abstract
Pancreatic ductal adenocarcinoma is a most deadly malignancy, with a 5-year survival rate of ~7%. Chemotherapy is the main treatment strategy of this disease. However, the high rate of resistance to chemotherapeutic agent contributes to poor prognosis. MicroRNAs are essential for the initiation, progression and chemoresistance of human malignancies. Previous studies have shown that miRNA-1285 participates in renal cell carcinoma and hepatocellular carcinoma. However, its roles in pancreatic ductal adenocarcinoma are poorly understood. In this study, we confirmed that miR-1285 was significantly down-regulated in gemcitabine-resistant pancreatic cancer cell lines by qRT-PCR. We found that miR-1285 suppressed cell proliferation as well as increased the sensitivity of PDAC cells to gemcitabine by CCK8 assays in vitro. Results from transwell assay indicated that miR-1285 inhibited pancreatic cancer cell migration and invasion. Experiments using different cell lines got identical results. All those results demonstrated that miR-1285 act as tumor suppressor of pancreatic cancer. To our knowledge, this study is the first to elucidate the function of miR-1285 in pancreatic cancer. Western blotting analysis verified that miR-1285 negatively regulated YAP1 protein level, together with EGFR and β-catenin. YAP1 is a known oncoprotein of pancreatic cancer. As silencing of YAP1 activity might be beneficial in cancer prevention and treatment, our results suggest that miR-1285 might serve as a novel therapeutic target for miRNA-based therapy in pancreatic cancer. Further research elucidating the exact mechanisms of miRNA-1285 function and the correlation between miR-1285 levels in tissues or serum and clinical characteristics of pancreatic cancer is needed later.

Abstract
The concentration distributions, compositional profiles and seasonal variations of 17 perfluoroalkyl acids (PFAAs) in PM10 (particles with aerodynamic diameters < 10 μm) were determined in seven coastal cities of the Bohai and Yellow Seas. The detection rates of perfluorooctanoic acid (PFOA) and short-chain components (perfluoroalkyl carboxylic acids (PFCAs) with ≤7 carbon atoms and perfluoroalkane sulfonic acids (PFSAs) with ≤5 carbon atoms) were much higher than those of other long-chain PFAA species. The annual average concentration of total PFAAs in PM10 ranged from 23.6 pg/m3 to 94.5 pg/m3 for the sampling cities. The monthly mean concentrations of PFAAs in PM10 in some sampling cities reached a peak value in winter, while no significant seasonal differences presented in other cities. High concentrations of PFAAs in the northern cities generally occurred during the local heating period (from November to March). Generally, the dominant components of PFAAs were PFOA and perfluorobutyric acid (PFBA). Some significantly positive correlations (p < 0.01) between the 10 dominant components were revealed in the sampling cities, which implied similar sources and fate behaviors. Based on the simulated 72-hr backward trajectory tracking of air masses, the clustering results demonstrated the sampling cities were affected mainly by the atmospheric transport in sequence from the northwest, the southwest and the open seas, and many transport trajectories of air masses passed by the local fluorine chemical manufacturers in Liaoning, Shandong, Jiangsu, and Hubei Provinces. The estimated average daily intake (ADI) corresponding to the residents in different age groups indicated insignificant contributions to PFOA and perfluorooctane sulfonate (PFOS) exposures by inhalation of PM10 compared to ingestion by daily diet, while the higher ADI of PFOA than the reported levels for adults should be a concern. The calculated hazard ratios (HR) exhibited low noncancer risks by inhalation exposure to PFOA and PFOS in PM10.

Abstract
A series of field samples including ambient air (gaseous and particulate phases), dust fall, surface soil, rhizosphere soil and cabbage tissues (leaf, root and core), were collected in vegetable bases near a large coking manufacturer in Shanxi Province, Northern China, during a harvest season. A factor analysis was employed to apportion the emission sources of polycyclic aromatic hydrocarbons (PAHs), and the statistical results indicated coal combustion was the dominant emission source that accounted for different environmental media and cabbage tissues, while road traffic, biomass burning and the coking industry contributed to a lesser extent. A structural equation model was first developed to quantitatively explore the transport pathways of PAHs from surrounding media to cabbage tissues. The modeling results showed that PAHs in ambient air were positively associated with those in dust fall, and a close relationship was also true for PAHs in dust fall and in surface soil due to air-soil exchange process. Furthermore, PAHs in surface soil were correlated with those in rhizosphere soil and in the cabbage leaf with the path coefficients of 0.83 and 0.39, respectively. PAHs in the cabbage leaf may dominantly contribute to the accumulation of PAHs in the edible part of cabbages.

Abstract
Samples of ambient air (including gaseous and particulate phases), dust fall, surface soil, rhizosphere soil, core (edible part), outer leaf, and root of cabbage from eight vegetable plots near a large coking manufacturer were collected during the harvest period. Concentrations, compositions, and distributions of parent PAHs in different samples were determined. Our results indicated that most of the parent PAHs in air occurred in the gaseous phase, dominated by low molecular weight (LMW) species with two to three rings. Specific isomeric ratios and principal component analysis were employed to preliminarily identify the local sources of parent PAHs emitted. The main emission sources of parent PAHs could be apportioned as a mixture of coal combustion, coking production, and traffic tailing gas. PAH components with two to four rings were prevailing in dust fall, surface soil, and rhizosphere soil. Concentrations of PAHs in surface soil exhibited a significant positive correlation with topsoil TOC fractions. Compositional profiles in outer leaf and core of cabbage, dominated by LMW species, were similar to those in the local air. Overall, the order of parent PAH concentration in cabbage was outer leaf > root > core. Partial correlation analysis and multivariate linear stepwise regression revealed that PAH concentrations in cabbage core were closely associated with PAHs present both in root and in outer leaf, namely, affected by adsorption, then absorption, and translocation of PAHs from rhizosphere soil and ambient air, respectively.

Abstract
Seventeen fresh lunates with stage III Kienböck's disease were scanned with micro-computed tomography. Four regions of interest were selected to measure trabecular parameters, which were compared with those from normal lunates. Within the three regions in the distal surface, there was more compact trabecular bone in the middle region when compared with the palmar and dorsal regions. In the central part, the trabeculae of the Kienböck's lunates were much thicker than those in normal lunates. The diameters of the palmar nutrient foramina of the Kienböck's lunates were significantly smaller than those in normal lunates. In affected lunates, the bony disruptions were mostly located in the palmar or dorsal areas, which were shown from trabecular bone structure analysis to be structurally weaker. This leads to separation of the distal part of the fractured bone, disruption of the blood supply, poor bone remodelling and proneness to secondary fracture and eventual collapse.

Abstract
OBJECTIVE To perform a systematic review and meta-analysis of the comparative studies reporting oncological and renal function outcomes of segmental ureterectomy (SU) versus radical nephroureterectomy (RNU) for upper tract urothelial carcinomas (UTUC). MATERIALS AND METHODS A literature search on Pubmed, Embase, and the Cochrane library was conducted according to the PRISMA guidelines, and a meta-analysis was performed to assess cancer-specific survival (CSS), overall survival (OS), recurrence-free survival (RFS), intravesical recurrence free survival (IVRFS) and surgery-related variations in estimated glomerular filtration rate (eGFR). RESULTS A total of 11 retrospective studies with 3963 patients who underwent either SU (n = 983; 24.8%) or RNU (n = 2980; 75.2%) were included. Although patients treated with SU were more likely to be diagnosed with favorable pathological features, the meta-analysis of unadjusted data revealed no significant difference between both groups in terms of CSS (HR 0.90, p = 0.33) and OS (HR 0.98, p = 0.93). Accordingly, the meta-analysis of adjusted data confirmed equivalent CSS (HR = 0.90, p = 0.47) between SU and RNU. Similarly, no significant difference was found in terms of RFS (HR 1.06, p = 0.72) and IVRFS (HR 1.35, p = 0.39). However, a significant decreased risk of impaired renal function was observed after SU when compared to RNU (mean eGFR difference = 9.32 ml/1.73 m2, p = 0.007). CONCLUSION Although adverse patient and tumor characteristics were not equally balanced between treatment arms, our systematic review and meta-analysis supports similar oncological outcomes between SU and RNU, with better preservation of renal function after SU. As such, SU should be preferably used as the first-line treatment for low-risk ureter tumors, while considered for selected cases of high-risk disease.

Abstract
Speckled (Spc), an X-ray-induced lethal mutant of Bombyx mori, exhibits a mosaic dark-brown-spotted larval epidermis in both sexes and egg-laying problems only in females. Here, we report the morphological characterization and molecular mapping of the Spc mutant. Morphological investigations revealed that the epidermal ultrastructure of the small, dark-brown spots was more dense than that of the white regions in both Spc/+ mutants and wild type, and that the lethality of the Spc/Spc mutants occurred during early embryogenesis. Furthermore, the ovarioles and ovipositor were disconnected in approximately 85.5% of Spc/+ females, a further 2.5% had a connection between the ovarioles and ovipositor that was too narrow to lay eggs. The remaining females showed a normal connection similar to that of the wild type. We successfully narrowed down the location of the Spc mutation to a region on chromosome 4 that was ∼1041 kb long. Gene-prediction analysis identified 25 candidate genes in this region. Chromosome structure analysis indicated that a ∼305 kb deletion was included in the mapping region. Temporal and spatial reverse transcription PCR (RT-PCR) analysis showed that several genes in the mapped region are associated with the Spc mutant. Although the genes responsible for the Spc mutation were not definitively identified, our results further the current understanding of the complex mechanism underlying the multiple morphological defects in Spc mutants.

Abstract
The metastatic spread of cancer cells to distant sites represents the major cause of cancer-related deaths in breast cancer patients, and lungs are one of the most common sites for metastatic colonization. Developing a physiologically relevant tissue culture model to mimic lung colonization of breast cancer is crucial for the investigation of the biology of cancer metastasis and evaluation of drug treatment efficacy. Here, we describe an ex vivo lung colonization assay for breast cancer using the native three-dimensional (3D) lung extracellular matrix. The native matrix was isolated from murine lungs using a decellularization technique, and the preservation of extracellular matrix (ECM) composition, integrity and mechanical properties was confirmed. We showed that metastatic MDA-MB 231 and 4T1 cells invaded and colonized in the decellularized lung matrix, whereas only a small mass of non-metastatic MCF7 cells survived under the same condition. Furthermore, knockdown of ZEB1, an epithelial-mesenchymal transition (EMT) inducer, significantly reduced invasion and colonization of MDA-MB 231 cells in the decellularized lung, suggesting an important role of EMT in breast cancer metastasis. We conclude that the decellularized lung retains the biophysical and biochemical properties of the lung ECM and provides a powerful tool to investigate the lung colonization of breast cancer.

Abstract
The large yellow croaker (Larimichthys crocea) is one of the largest marine net-cage cultured species in the oceans around China. In the present study, we isolated and characterized 13 polymorphic microsatellite markers from genomic libraries of L. crocea. Loci were screened for 10 wild specimens from 2 sites in southeast of China. All loci were polymorphic. The number of alleles per locus ranged from 2 to 21. The expected heterozygosity ranged from 0.233 to 0.838 and observed heterozygosity ranged from 0.527 to 0.935. Eleven loci were highly informative (polymorphic information content >0.5). Significant deviation from Hardy-Weinberg equilibrium was observed at 3 loci after Bonferroni's correction. The microsatellite loci may be valuable tools for studying the genetic diversity and genetic structure for conservation planning of the fish.

Abstract
Altered SERT and DAT availabilities during treatment with escitalopram were investigated with [(123)I]2β-carbomethoxy-3β-(4-iodophenyl)tropane (β-CIT) SPECT in a series of patients fulfilling the criteria for unipolar major depressive disorder (MDD). 27 patients (10m, 42±16y) with diagnosis of MDD were recruited for the study. All patients underwent neuropsychiatric testing for assessment of Hamilton Depression (HAM-D) and Beck Depression Inventory (BDI) scores. At baseline, [(123)I]β-CIT SPECT recordings were acquired 4h (SERT-weighted) and 20-24h p.i (DAT-weighted). Follow-up scans and neuropsychiatric testing were performed after six weeks of stable escitalopram medication. Voxel-wise parametric maps of specific/ non-specific ratios-1 (~BPND) were calculated. At baseline, DAT-weighted BPND was 5.06±0.81 in striatum and SERT-weighted BPND was 0.94±0.18 in thalamus. There were significant negative correlations with age for DAT in striatum (R=-0.60; p<0.01) and SERT in thalamus (R=-0.45; p<0.05). Under SSRI treatment there was an apparent 42% occupancy of SERT in thalamus (p<0.0001), whereas DAT availability increased significantly by 20% in striatum (p<0.001); higher apparent SERT occupancy in thalamus was associated with lesser DAT increase in striatum (R=-0.62; p<0.005). The low apparent SERT occupancy may be confounded by alterations in SERT expression during treatment. Thus, [(123)I]β-CIT SPECT revealed age-dependent declines in DAT and SERT availabilities in un-medicated MDD patients, comparable to that seen previously in healthy controls. At follow-up, the SSRI-evoked increase in DAT was less pronounced in the older patients, even though apparent SERT occupancy and clinical improvement were not age-dependent. Present findings may have implications for escitalopram dosage and side effect profile in younger MDD patients.

Abstract
UNLABELLED The aim of this study was to determine the response of advanced-stage non-small cell lung cancer (NSCLC) patients with or without EGFR mutations to platinum-based chemotherapy with or without gefitinib maintenance. Patients were treated with four cycles of platinum-based chemotherapy. Patients with wild-type EGFR were observed (group 1; n=15). EGFR mutation-positive patients were randomly assigned to observation (group 2; n=7) or gefitinib maintenance (group 3; n=7). The median patient age was 59 years. The 1-year progression-free survival rates in groups 1, 2, and 3 were 6.7%, 28.6%, and 57.1%, respectively (p = 0.049); the 1-year overall survival rates were 53.3%, 57.1 %, and 100%, respectively (p = 0.111). The results indicate that patients with advanced-stage NSCLC with EGFR mutations have a better response to chemotherapy followed by gefitinib than chemotherapy alone and a better response to chemotherapy than wild-type patients. KEYWORDS chemotherapy, gefitinib, NSCLC, tyrosine kinase inhibitors.

Abstract
Ten patients with metacarpophalangeal joint locking of the thumb were studied. Three of them underwent surgical release. During surgery, it was found that the radial sesamoid was seated in a cartilage defect on the volar aspect of the metacarpal head. It appeared that the defect was created by the proximal edge of sesamoid. When the abductor pollicis brevis and flexor pollicis brevis muscles were partially detached from their insertion at the base of the proximal phalanx, the locking could be successfully released. We hypothesize the mechanism of the metacarpophalangeal joint locking of the thumb in our cases was a hyperextension injury that displaced the radial sesamoid distally and radially. In turn, the sesamoid's pointed proximal edge wore a groove in the cartilage on the metacarpal head, and under abductor pollicis brevis and flexor pollicis brevis tension, the radial sesamoid was locked into the cartilage defect; thereby causing locking of the joint.

Abstract
The plant cell wall is an important factor for determining cell shape, function and response to the environment. Secondary cell walls, such as those found in xylem, are composed of cellulose, hemicelluloses and lignin and account for the bulk of plant biomass. The coordination between transcriptional regulation of synthesis for each polymer is complex and vital to cell function. A regulatory hierarchy of developmental switches has been proposed, although the full complement of regulators remains unknown. Here, we present a protein-DNA network between Arabidopsis transcription factors and secondary cell wall metabolic genes with gene expression regulated by a series of feed-forward loops. This model allowed us to develop and validate new hypotheses about secondary wall gene regulation under abiotic stress. Distinct stresses are able to perturb targeted genes to potentially promote functional adaptation. These interactions will serve as a foundation for understanding the regulation of a complex, integral plant component.

Abstract
Key insights into the behavior of materials can be gained by observing their structure as they undergo lattice distortion. Laser pulses on the femtosecond time scale can be used to induce disorder in a "pump-probe" experiment with the ensuing transients being probed stroboscopically with femtosecond pulses of visible light, x-rays, or electrons. Here we report three-dimensional imaging of the generation and subsequent evolution of coherent acoustic phonons on the picosecond time scale within a single gold nanocrystal by means of an x-ray free-electron laser, providing insights into the physics of this phenomenon. Our results allow comparison and confirmation of predictive models based on continuum elasticity theory and molecular dynamics simulations.
