Abstract
OBJECTIVE Membranous nephropathy (MN) is a leading cause of nephrotic syndrome in adults, but the treatment of MN remains controversial. Rituximab, a possible alternative treatment option, represented a new therapeutic hope for the treatment of membranous nephropathy (MN). We performed a meta-analysis to perform the efficacy and safety of rituximab therapy. MATERIALS AND METHODS Either randomized controlled trials (RCTs), cohort studies or case studies were eligible for review and were performed in Medline, Embase, Web of Science, Cochrane database with the computerized searches. The primary outcome measure was remissions and the endpoint outcomes. We assessed the following studies methodological quality independently by using the Cochrane Collaboration tool for assessing risk of bias scale. The primary meta-analyses were performed using fixed or random effects models due to a1n expected clinical diversity. RESULTS Five trials with a total of 351 patients were included. We found significant difference between rituximab and the placebo group on complete remissions rate (OR=1.6, 95%; CI=0.96, 2.66; I2 of 0% indicating no heterogeneity) and eGFR (MD=-0.69, 95% CI=-14.53, 0.73). The factors of remission and no remission MN patients who received treatment with rituximab on remission were proteinuria and albumin, which reported different (MD=7.20, 95% CI=-9.07, -5.33) (MD=10.70, 95% CI=7.23, 14.17). But remains high risk of infusion reactions (OR= 81.37, 95% CI=4.89, 1354.41). No evidence of significant risk of bias was reported. CONCLUSIONS Rituximab had a beneficial effect and remissions of proteinuria on MN during follow-up times, but some adverse events were still unknown. Taking consideration of long-term therapeutic side effects and dose of the drug, we suggest that rituximab might replace cyclophosphamide and steroids as first-line immunosuppressive therapy in MN patients.

Abstract
Recent studies have shown that intratumoral heterogeneity is prevalent in esophageal squamous cell cancer (ESCC) based on DNA sequencing and chromosome analysis in multiple regions from the same tumor. This study aimed to investigate the expression of ZNF750, EP300, MTOR and KMT2D and their intratumoral heterogeneity (ITH) in patients with ESCC. A total of 106 cases, who underwent esophagectomy from 2008 to 2010, with two foci from each case, were tested by immunohistochemistry(IHC) as well as 12 cases were tested by RNAscope in this study.We found that 58/106 (54.72%), 66/106 (62.26%), 75/106 (70.75%%) of ESCC showed high expression of ZNF750, EP300, MTOR, respectively by IHC, and 8/12 (66.67%), 10/12 (83.33%), 4/12 (33.33%) and 6/12 (50%) showed high expression of ZNF750, EP300, MTOR and KMT2D, respectively by RNAscope. Multivariate analysis showed that MTOR expression was an independent infavorable prognostic factor of overall survival (OS) (HR = 1.921; P = 0.000). This study also found that 44/106(4151%), 37/106 (34.91%), 39/106(36.79%) of ESCC showed heterogeneous expression of ZNF750, EP300 and MTOR respectively by IHC, 8/12(66.67%), 8/12(66.67%), 4/12(33.33%), 4/12(33.33%) of ZNF750, EP300, MTOR and KMT2D respectively by RNAscope, IHC and RNAscope could successfully detect a high prevalence of ITH. In conclusion, findings of this study showed that ZNF750, EP300, MTOR and KMT2D heterogeneously expressed in ESCC. High expression of ZNF750 related to a better outcome, while EP300 and MTOR related to a poor prognosis.

Abstract
Complete mitochondrial DNA D-loop sequences of 1105 individuals were used to assess the diversity of maternal lineages of cattle populations in China. In total, 250 taurine and 88 zebu haplotypes were identified. Five main haplogroups-T1a, T2, T3, T4 and T5-were identified in Bos taurus, whereas Bos indicus harbored two haplogroups-I1 and I2. Our results suggest that the distribution of T1a in Asia was concentrated mainly in the northeast region (northeast China, Korea and Japan); haplogroups T2, T3 and T4 were predominant in Chinese cattle; and T5 was sporadically detected in Mongolian and Pingwu cattle. In contrast to the widespread presence of I1, I2 was distributed only in southwestern China (Yunnan-Guizhou Plateau and the Tibet Autonomous Region) and Xinjiang Uygur Autonomous Region. This is the first time that all five taurine haplogroups and two zebu haplogroups have been found in Mongolian cattle. In addition, eight individuals in Tibetan cattle carried the Bos grunniens mtDNA type. The high mtDNA diversity (H = 0.904 ± 0.008) and the weak genetic structure among the 57 Chinese cattle breeds/populations are consistent with their complex historical background, migration route and ecological environment.

Abstract
Alzheimer's disease (AD), a neurodegenerative disease, is diagnosed by impaired learning and memory in elderly individuals. Tectochrysin (TEC) is a flavonoid compound isolated from Alpinia Oxyphylla Miq., which has been traditionally used for the treatment of diarrhea, salivation, diuresis and dementia. In our study, model mice with AD induced by intracerebroventricular injection of Aβ1-42 were used to determine the role of TEC on memory retrieval. The results revealed that AD mice received intracerebroventricular injection of TEC (140 µg/kg) showed improved spatial memory performance and down-regulated expressions of β-secretase and accumulation of Aβ1-42 in brain tissues. TEC also decreased the concentration of malondialdehyde and total cholinesterase, and increased activities of both antioxidant superoxide dismutase and glutathione peroxidase in hippocampal and cortex. In addition, Aβ1-42 induced injury of neurons in hippocampal CA1 layer was rehabilitated in TEC treated mice. These findings highlight the beneficial role of TEC in amnestic mice induced by Aβ1-42 through the down-regulation of Aβ1-42 accumulation, oxidative stress, and total cholinesterase. Our study indicated a therapeutic potential of TEC in the treatment of AD.

Abstract
Sumac is universally known for its abundance of raw lacquer. Toxicodendron vernicifluum (Stokes) F.A. Barkley is one of the widely distributed native sumac cultivars. To accelerate sumac breeding for more prolific, high-quality, and robust cultivars, it is essential to explore its lacquer metabolism. However, transcriptomic and genomic data available for sumac are still limited. In this study, we generated the transcriptomic profiles of triploid Toxicodendron vernicifluum CV. Dahongpao (Dahongpao) and diploid T. vernicifluum and Toxicodendron vernicifluum CV. Huoyanzi (Huoyanzi), with 87856 unigenes. About 53% of these unigenes were annotated using Nr, Swiss-Prot, Kyoto Encyclopedia of Genes and Genomes (KEGG), Cluster of Orthologous Groups (COG) and Gene Ontology (GO). We identified nine differentially expressed candidate genes associated with type III polyketide synthase formation, which is the first step in urushiol biosynthesis. Additionally, a number of simple sequence repeats (EST-SSRs) were identified in T. vernicifluum for further molecular marker-assisted breeding. This study is the first report of Toxicodendron species transcriptome.

Abstract
Background Gitelman syndrome is an autosomal recessive inherited renal disorder characterized by hypokalemia, hypomagnesemia, and hypocalciuria. Since the symptoms are not severe and laboratory results are not always clear, Gitelman syndrome can go unnoticed by physicians. Here, we report our experiences with a patient that presented with hypokalemia and proteinuria; genetic analysis revealed a new homozygous mutation in the SLC12A3 gene. Case presentation A 47-year-old man presented with hypokalemia and proteinuria. He had come to the hospital with the same symptoms 11 months and 3 years prior. His laboratory tests showed hypokalemia, hypocalciuria, and increased plasma angiotensin-2 activity. His renal pathology was consistent with the development of minimal lesions. Genetic analysis found a new homozygous mutation in exon 6 on the SLC12A3 gene (p.Trp281Arg) in the patient and in his brother; his mother and sister were diagnosed as heterozygous carriers of the same gene mutation. Finally, the patient was diagnosed with Gitelman syndrome. Conclusions This case is the first to report a homozygous mutation in the 841th nucleotide of exon 6 on the SLC12A3 gene (p.Trp281Arg), which may cause Gitelman syndrome. At the same time, this report might stimulate interest in discussing the relationship between different mutations in the SLC12A3 gene and renal pathology.

Abstract
Injecting supercritical CO2 into gas reservoir is a novel trial to improve condensate gas recovery and decrease the hydrocarbon liquid dropout. A good understanding of the effect of supercritical CO2 on the phase behavior properties of these hydrocarbons is essential for accurately forecasting the displacing performance and storing process of the reservoirs with numerical simulators. This paper presents novel phase behavior experimental procedures and phase equilibrium evaluation methodology for gas-condensate phase system mixed with supercritical CO2 over a wide range of temperatures and pressures. A unique phase behavior phenomena was also reported. The mass transfer between two vapour phases was also measured. In order to interpret and identify the interface property between condensate gas and supercritical CO2, a multiphase thermodynamic VLV equilibrium model was established. Finally, taken YKL condensate gas in Northwest China as an example, the region where the conditions in terms of pressure, temperature and CO2 concentration can yield VLV equilibrium was found. The calculation results of multiphase thermodynamic model for condensate-CO2 system in this paper are close to the experimental data and can truthfully reflect the phase behavior of interface between CO2 and condensate gas. The research results indicate that it is the existence of the interface between CO2 and condensate gas that makes CO2 possible be an attractive option to successfully displace condensate gas and decrease CO2 emissions.

Abstract
Recombinant adeno-associated virus (rAAV)rh74.MCK.GALGT2 is a muscle-specific gene therapy that is being developed to treat forms of muscular dystrophy. Here we report on an isolated limb infusion technique in a non-human primate model, where hindlimb blood flow is transiently isolated using balloon catheters to concentrate vector in targeted leg muscles. A bilateral dose of 2.5 × 1013 vector genomes (vg)/kg/limb was sufficient to induce GALGT2-induced glycosylation in 10%-60% of skeletal myofibers in all leg muscles examined. There was a 19-fold ± 6-fold average limb-wide increase in vector genomes per microgram genomic DNA at a bilateral dose of 2.5 × 1013 vg/kg/limb compared with a bilateral dose of 6 × 1012 vg/kg/limb. A unilateral dose of 6 × 1013 vg/kg/limb showed a 12- ± 3-fold increase in treated limb muscles compared to contralateral untreated limb muscles, which received vector only after release into the systemic circulation from the treated limb. Variability in AAV biodistribution between different segments of the same muscle was 125% ± 18% for any given dose, while variability between the same muscle for any given treatment dose was 45% ± 7%. These experiments demonstrate that treatment of muscles throughout the leg with rAAVrh74.MCK.GALGT2 can be accomplished safely using an isolated limb infusion technique, where balloon catheters transiently isolate the limb vasculature, but that intra- and inter-muscle transduction variability is a significant issue.

Abstract
Objective: To compare the use of cone beam computed tomography (CBCT) and conventional approach (clinical probing and periapical radiograph) in assessing furcation involvement (FI) of maxillary molars and making treatment decisions. Methods: Thirty-two subjects were selected from the pool of patients at the Department of Periodontology, Tianjin Stomatology Hospital & Hospital of Stomatology, NanKai University from January 2015 to December 2016. All the patients have a diagnosis of generalized chronic periodontitis. Ninety-five maxillary molar with FI from the radiography database were analysed. Two doctors used conventional approach and CBCT images to assess FI and make treatment decision respectively. If the clinical and radiographic findings did not clearly indicate a distinct periodontal therapy, two treatment options were considered. Results: There was statistical difference of the FI diagnosis between traditional group and CBCT group assessment of the 95 molars (P=0.000). Thirty-five maxillary molars (36.8%, 17 patients) got two treatment recommendations by conventional approach but 7 (7.4%, 5 patients) by CBCT-based approach. When with the less invasive treatment recommendation, there was statistical difference between conventional approach and CBCT-based approach (P=0.001). An agreement was observed in 63.2% (60/95) of the teeth, while in another 29.5% (28/95) the CBCT-based treatment decision was more invasive than the conventional approach. When with the more invasive treatment recommendation, there was also statistical difference between two approaches (P=0.045). An agreement was observed in 86.3% (82/95) of the teeth, while in another 3.2% (3/95) the CBCT-based treatment decision was more invasive than the conventional approach. Conclusions: CBCT images of maxillary molars may provide detailed information of FI and a reliable basis for treatment decision.

Abstract
In the present investigation, the antitumor effect of ferruginol (FGL) in SK-Mel-28 human malignant melanoma cells was studied. To investigate the cytotoxic property of FGL, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was used. Results revealed that prolonged treatment duration decreases the IC25, IC50, and IC75 concentrations of FGL. The cytotoxicity was further confirmed by lactate dehydrogenase assay. As evident from comet assay, FGL induces DNA damage in a dose-dependent manner. Annexin V and 7-ADD assays showed that FGL-induced DNA damage triggers apoptosis-mediated cell death as confirmed by caspase-3 activity assay. As seen through Western blotting, FGL increases phosphorylation of p38 and nuclear translocation of NF-κB. Further, it was observed that p38 phosphorylation is responsible for NF-κB translocation to the nucleus. Further, inhibition of p38 phosphorylation and translocation of NF-κB decrease caspase-3 activity. The above finding confirms that caspase-3 activation is mediated through P-p38 and nuclear translocation of NF-κB. The present findings indicate that FGL significantly suppresses the proliferation of SK-Mel-28 cells in a dose- and time-dependent manner through induction of apoptosis. Furthermore, FGL executes apoptosis through phosphorylation of key protein such as p38 and translocation of NF-κB into the nucleus.

Abstract
A simple and rapid ultra-performance liquid chromatography⁻tandem mass spectrometry (UPLC⁻MS/MS) coupled with a one-step liquid-liquid extraction method has been developed and validated for the simultaneous determination of two flavonoids (chrysin, tectochrysin) from Alpinia oxyphylla fruits extract in rat plasma. Plasma samples were extracted with diethyl ether and separated on an ACQUITY UPLC BEH C18 column (100 mm × 2.1 mm, 1.7 μm) using gradient elution consisting of 0.1% formic acid in water (A) and methanol (B). The multiple reaction monitoring (MRM) mode with electrospray ionization in the positive ion mode was used for detection. The linear range was 0.1 ng/mL to 50 ng/mL for chrysin and tectochrysin, respectively. The accuracy (relative error, RE%) ranged from -8.8% to 7.5% and the intra-day and inter-day precision were within 15% and had a mean extraction recovery rate of 80.3% to 86.7%. The validated method was applied to a comparative pharmacokinetic study after oral administration of Alpinia oxyphylla fruit ethanol extract between normal rats and dementia rats. The area under the curve (AUC) and peak plasma concentration (Cmax) of the two constituents were remarkably increased in dementia rats than in normal rats.

Abstract
Objective:To compare the diagnostic potential of HE staining, enzymatic histochemistry and immunohistochemistry in displaying lymphatic vessel of laryngeal carcinoma.Method:We recruited 3 patients who were pathologically diagnozed as laryngeal squamous cell carcinoma and were performed total laryngectomy in the First Affiliated Hospital of Shanxi Medical University from April to December 2016. According to the improved Kawamoto's Film Method, frozen specimens of whole laryngeal squamous cell carcinoma were made. Immunohistochemistry, using lymphatic endothelial cell specific marker D2-40, enzymatic histochemistry (5-nucleotidase) and HE staining were used to stain the frozen sections of laryngeal carcinoma. Then the staining results of lymphatic vessels in the specimens of laryngeal carcinoma were compared by the optical microscope. Result:The background of HE and D2-40 immunohistochemical staining were clear.5-Nase staining had a deeper background and more nonspecific staining. By immunohistochemistry,102(97.1%,102/105)blood vessels were identified, and 3(2.9%) were partly positive. While using 5-Nase,56(53,3%,56/105)blood vessels were identified. In 105 lumen structures that could not be clearly judged,95(90,5%)were positive by D2-40,while by 5-Nase staining,89(84.8%)were positive including a large number of glands.In addition, positive cells scattered in dots or clusters were observed in 5-Nase and D2-40 staining sections, but these cells or structures could not be identified by HE staining. Conclusion:D2-40 immunohistochemistry may have certain applied value in the study of lymphatic vessels associated with laryngeal carcinoma.

Abstract
Neuroinflammatory responses play a crucial role in the pathogenesis of Alzheimer's disease (AD). Our previous study demonstrated that petroleum ether extracts from Alpiniae Oxyphyllae Fructus(AOF) could attenuate lipopolysaccharide (LPS)-induced learning and memory impairment in mice, which could be associated with its inhibitory effect on neuroinflammation. Therefore, our present study is to investigate the potential therapeutic neuroprotective effects of nootkatone (NKT) on an AD mouse model induced by intracerebroventricular injection of LPS. We found that NKT (10 mg/kg) group showed good performance in behavior experiments including Y-maze test and Morris water maze test. The results of histopathological examination and immunohistochemical analysis showed that LPS induced degeneration of neurons and activation of microglia particularly in hippocampus and NKT (10 mg/kg) reversed these changes. Enzyme linked immunosorbent assay and western blot analysis also demonstrated that the model group had increased expression of IL-1β, IL-6, TNF-α, NLRP3 and NF-κB p65, especially in hippocampus relative to sham-operated group, and NKT (10 mg/kg) decreased the high expression of these inflammatory cytokines. Collectively, these data indicated that LPS-induced learning and memory impairments in mice could be improved by NKT, which was associated with attenuating neuroinflammatory responses. Our study indicated that NKT could act as a potential therapeutic agent for the treatment of neuroinflammation and AD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alpinae Oxyphyllae Fructus (AOF) with warming and tonifying the kidney and spleen, anti-salivation, anti-polyuria and anti-diarrhea functions is the dried ripe fruits of Alpinia oxyphylla Miq. (Zingiberaceae). As a traditional Chinese medicine, its application history is very long. AIMS OF THE STUDY The purpose of our study is to investigate the effects of different solvent extracts from AOF on lipopolysaccharide (LPS)-induced animal model of Alzheimer's disease (AD) to elucidate the traditional medical theories with modern pharmacological methods and provide a reference for further clarifying its active components and mechanisms. MATERIALS AND METHODS The method of stepwise screening was adopted in this paper. The animals were divided into 9 groups, including control (CT) group, model (MD) group, donepezil (DPZ) group, total extract (TT) group, petroleum ether extract (PE) group, chloroform extract (CF) group, ethyl acetate extract (EA) group, n-butanol extract (NB) group and water extract (WT) group. The anti-amnesic effects of different solvent extracts from AOF were measured in LPS-induced memory deficits mice by Y maze test and Morris water maze (MWM) test. Hematoxylin eosin (HE) staining was applied to observe pathological changes in hippocampus and cerebral cortex tissue of different groups. Biochemical indicators including ionized calcium-binding adaptor molecule 1 (IBA-1), interleukin beta 1 (IL-1β), Aβ1-42 and hyperphosphorylated tau proteins (p-tau) in hippocampus and cortex after treatment with LPS were measured according to the manufacturer's instructions of ELISA kits. HPLC was used to evaluate the major components of different extracts. RESULTS It was found that successive intragastric administration of AOF (360 mg/kg) extracts for 14 days showed different degrees of improvement on LPS-induced AD model as measured by Y-maze test, Morris water maze test, and Histopathological examination. Moreover, the results of ELISA suggested petroleum ether (PE) extracts were worth recommending for inhibiting the high level of IBA-1, IL-1β, Aβ1-42 and p-tau in hippocampus and cortex after treatment with LPS. CONCLUSIONS The present study demonstrated for the first time that AOF attenuated LPS-induced learning and memory impairment, which may be associated with its inhibitory effect on neuroinflammation, amyloids-β (Aβ) deposition and p-tau. This research provided a theoretical basis for elucidating the traditional theory of AOF, and was also the stepping stone to the next step.

Abstract
Hepatic glutamate uptake and conversion to glutamine is critical for whole-body N metabolism, but how this process is regulated during growth is poorly described. The hepatic glutamate uptake activities, protein content of system [Formula: see text] transporters (EAAC1, GLT-1) and regulatory proteins (GTRAP3-18, ARL6IP1), glutamine synthetase (GS) activity and content, and glutathione (GSH) content, were compared in liver tissue of weaned Angus steers randomly assigned (n = 8) to predominantly lean (growing) or predominantly lipid (finished) growth regimens. Steers were fed a cotton seed hull-based diet to achieve final body weights of 301 or 576 kg, respectively, at a constant rate of growth. Liver tissue was collected at slaughter and hepatic membranes fractionated. Total (75%), Na+-dependent (90%), system [Formula: see text]-dependent (abolished) glutamate uptake activity, and EAAC1 content (36%) in canalicular membrane-enriched vesicles decreased as steers developed from growing (n = 6) to finished (n = 4) stages, whereas Na+-independent uptake did not change. In basolateral membrane-enriched vesicles, total (60%), Na+-dependent (60%), and Na+-independent (56%) activities decreased, whereas neither system [Formula: see text]-dependent uptake nor protein content changed. EAAC1 protein content in liver homogenates (n = 8) decreased in finished vs. growing steers, whereas GTRAP3-18 and ARL6IP1 content increased and GLT-1 content did not change. Concomitantly, hepatic GS activity decreased (32%) as steers fattened, whereas GS and GSH contents did not differ. We conclude that hepatic glutamate uptake and GS synthesis capacities are reduced in livers of finished versus growing beef steers, and that hepatic system [Formula: see text] transporter activity/EAAC1 content is inversely proportional to GTRAP3-18 content.

Abstract
PurposeTo determine what impact rapid ascension to a high-altitude environment has on the retina with the aim of preventing and treating high-altitude oculopathy.Patients and methodsParticipants in the study were members of the Chinese military assigned to the high-altitude environment of the Tibetan plateau. Ninety-one participants were enrolled in the study. Optical coherence tomography was used to measure the thickness of retina-related indicators. Measurements were taken before and after exposure to the high-altitude environment and upon return to the baseline altitude.ResultsFollowing exposure to the high-altitude environment in Tibet, there was a significant increase in retinal nerve fiber layer (RNFL) thickness in the temporal and nasal quadrants of the optic disc, whilst a significant decrease in RNFL thickness in the inferior optic disc was also observed. A significant increase in RNFL thickness in the superior and inferior macula was also evident, along with a significant increase in the ganglion cell layer thickness in the superior macula. Upon return to the baseline altitude, all measurements returned to baseline levels except for the RNFL of the inferior macula, which was significantly thicker. Pathological changes were also documented in the eyes of nine participants upon returning to baseline altitude, including ischemic optic neuropathy, myopia, and cortical amaurosis.ConclusionsThe high-altitude environment can have a negative impact on the health of the retina and may contribute to the incidence of various eye diseases. This study deepens the understanding of what impact a high-altitude environment has on retina and provides reliable data for blindness prevention and treatment.

Abstract
The sesquiterpene nootkatone (NKT), isolated from Alpiniae oxyphyllae Fructus, was shown to possess protective effects on neurons. In our study, by using an Alzheimer's disease (AD) model of mice induced by intracerebroventricular (i.c.v.) injection of Aβ1-42 oligomers, we investigated the effects of NKT on memory impairment and further evaluated the pathological changes of mice. AD mice were treated by i.c.v. injection of NKT (at a dose of 0.02 mg/kg and 0.20 mg/kg) or vehicle (PBS) into the lateral ventricle once daily for 5 consecutive days. The behavioral tasks were performed, and levels of some biochemical indicators and histopathological changes of the brain were evaluated to elucidate the mechanism of NKT in the treatment of AD. The results revealed that NKT significantly improved the neurobehavioral performance of the AD mice in the Y-maze and Morris water maze tests. More importantly, NKT treatment decreased the malondialdehyde (MDA), Aβ as well as the acetylcholin esterase (AChE) levels in the mice brain, while increased the glutathione peroxidase (GSH-Px) levels with improved histopathological changes in the hippocampus. These findings provided evidences for the beneficial role of NKT in Aβ1-42-induced mice AD model linking to anti-oxidative and anti-AChE activities with inhibitory effect against Aβ accumulation.

Abstract
It is well known that both British and American Pekin ducks originated from China. However, the populations differ substantially in production performance, but the genetic changes involved are still poorly understood. Herein, we sequenced 24 individual Pekin ducks (eight from each population) with an average sequencing depth of more than 45× for each population (mean coverage of 6.29 per individual). Among these populations from three different countries, we identified a large number of SNPs and indels as well as many unique population variants, which can be used as population-specific molecular markers. Genomic comparisons among the three duck populations revealed many candidate genes as well as pathways and Gene Ontology categories that are putatively associated with meat yield in the British population, growth in the American population and brain development in all three populations. These findings will enable a better understanding of the artificial selection history of Pekin ducks and provide a valuable resource for future research on the breeding of this species.

Abstract
The present work characterizes the spatiotemporal variations of air pollution at four sites in Xi'an city. The investigations lasted for 1 year: January 1 through December 31, 2015. The concentrations of CO, NO2, O3, PM and SO2 were systematically monitored. The gray correlation analysis was used to correlate PM2.5 and gaseous pollutants. The formation mechanisms of sulfate and nitrate aerosols were discussed. Results clearly revealed severe air pollution by PM2.5, PM10 and NO2 at all four sites. Significant monthly variations were observed for PM2.5, PM10, SO2 and CO with the maximum values in December/January and minimum values in June/July. The O3 level showed an opposite trend. Spatially, high variations were observed for PM and some gaseous pollutants at individual sites. Gray correlation analysis revealed the significance of various major influencing factors on seasonal PM2.5 values at each site. In general, PM10, SO2 and NO2 affect the PM2.5 more than other pollutants. For a more efficient control of air pollution, a systematic spatial characterization of the seasonal variability of individual influencing factors is necessary.

Abstract
Cystic fibrosis (CF) is a multiorgan disease of the lungs, sinuses, pancreas, and gastrointestinal tract that is caused by a dysfunction or deficiency of the cystic fibrosis transmembrane conductance regulator (CFTR) protein, an epithelial anion channel that regulates salt and water balance in the tissues in which it is expressed. To effectively treat the most prevalent patient population (F508del mutation), two biomolecular modulators are required: correctors to increase CFTR levels at the cell surface, and potentiators to allow the effective opening of the CFTR channel. Despite approved potentiator and potentiator/corrector combination therapies, there remains a high need to develop more potent and efficacious correctors. Herein, we disclose the discovery of a highly potent series of CFTR correctors and the structure-activity relationship (SAR) studies that guided the discovery of ABBV/GLPG-2222 (22), which is currently in clinical trials in patients harboring the F508del CFTR mutation on at least one allele.

Abstract
OBJECTIVES Sensitive skin (SS) is a condition characterised by high reactivity, low tolerance, and susceptibility to allergies of the skin. Owing to changes in the environment and marketing strategies, as well as the increasing public awareness about skin care, attention to skin condition is gradually increasing. The aim of this study is to explore the differences in the skin barrier of SS and normal skin (NS). METHODS A questionnaire survey was conducted and basic indicators of the skin barrier were analysed. It was found that sebum secretion in the SS group was lower than that in the NS group, suggesting that the development of SS might be associated with sebum secretion and its specific components. Next, an ultra performance liquid chromatography-quadruple time-of-flight mass spectrometer was used to identify facial sebum components in female volunteers. RESULTS The results showed that the sebum of female volunteers with SS had high levels of ceramides, glycerophosphoethanolamines, and diacylglycerols, and low levels of glucosylceramides, glycerophosphoserines, glycerophosphocholines, and triacylglycerols. CONCLUSION Analysis of lipid functions suggested that the main reason for SS development in women might be a barrier dysfunction caused by excessive apoptosis and lack of water. Therefore, anti-allergy additives in cosmetic products that could inhibit apoptosis of keratinocytes and methods to maintain the stability of water molecules in the skin should be further studied.

Abstract
Zeolitic imidazolate framework-8 (ZIF-8) was introduced on the surface of fibers of a non-woven fabric made of polyethylene terephthalate (PET). The phase structure, morphology, textural properties and chemical structure were studied using X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen (N2) adsorption analyzer and Fourier transform infrared spectroscopy (FTIR). The XRD, SEM and FTIR results indicated that ZIF-8 had been successfully coated on the PET fibers. N2 adsorption analyses suggested that addition of ZIF-8 significantly increased the specific surface and micropore volume of composites. The PM2.5 removal experiment showed the filtration efficiency of ZIF-8/PET was twice as high as that of pure PET. Meanwhile, ZIF-8/PET also displayed a low pressure drop and good recycling performance. This research provided a facile method to deposit active ZIF-8 onto polymers with low air resistance, and that ZIF-8/PET was a good candidate as an air filter for PM2.5 removal. Zeolitic imidazolate framework-8 (ZIF-8) was introduced on the surface of fibers of a non-woven fabric made of polyethylene terephthalate (PET).![]()

Abstract
The current study aims to identify the pathogenic sites in a core pedigree of Usher syndrome (USH). A core pedigree of USH was analyzed by whole exome sequencing (WES). Mutations were verified by polymerase chain reaction (PCR) amplification and Sanger sequencing. Two pathogenic variations (c.849+2T>C and c.5994G>A) in MYO7A were successfully identified and individually separated from parents. One variant (c.849+2T>C) was nonsense mutation, causing the protein terminated in advance, and the other one (c.5994G>A) located near the boundary of exon could cause aberrant splicing. This study provides a meaningful exploration for identification of clinical core genetic pedigrees.

Abstract
AIM We aimed to investigate the potential role of endothelin-1 (ET-1) in the regulation of the expression of α-smooth muscle actin (α-SMA) in human myometrial fibroblasts. METHODS Primary myometrial fibroblasts were obtained from myometrium and were identified by immunocytochemical staining. Then, 1 × 107 cells were treated with ET-1 at a concentration of 0.1, 1.0, 10.0, or 100.0 nM for 24 h. To investigate the time course effects of ET-1 on the growth of fibroblasts, 1 × 107 cells were treated with 10.0 nM ET-1 for 6, 12, 24, and 48 h. Real-time quantitative PCR (qPCR) and Western blot analysis were used to determine the expression of α-SMA mRNA and protein, respectively. RESULTS Human myometrial fibroblasts were identified by immunohistochemistry. Compared with the control group, the expression levels of α-SMA mRNA and protein were identified in cells treated with ET-1 at a concentration of 0.1, 1.0, 10.0, or 100.0 nM for 24 h (P < 0.05). ET-1 treatment affected the expression of α-SMA mRNA and protein in a dose-dependent manner (P < 0.05). The induction of α-SMA mRNA and protein expression increased from 6 to 48 h. CONCLUSION The results show that ET-1 induces the expression of α-SMA in human myometrium in vitro.

Abstract
Alveolar epithelia play an essential role in maintaining the integrity and homeostasis of lungs, in which alveolar epithelial type II cells (AECII) are a cell type with stem cell potential for epithelial injury repair and regeneration. However, mechanisms behind the physiological and pathological roles of alveolar epithelia in human lungs remain largely unknown, partially owing to the difficulty of isolation and culture of primary human AECII cells. In the present study, we aimed to characterize alveolar epithelia generated from A549 lung adenocarcinoma cells that were cultured in an air-liquid interface (ALI) state. Morphological analysis demonstrated that A549 cells could reconstitute epithelial layers in ALI cultures as evaluated by histochemistry staining and electronic microscopy. Immunofluorescent staining further revealed an expression of alveolar epithelial type I cell (AECI) markers aquaporin-5 protein (AQP-5), and AECII cell marker surfactant protein C (SPC) in subpopulations of ALI cultured cells. Importantly, molecular analysis further revealed the expression of AQP-5, SPC, thyroid transcription factor-1, zonula occludens-1 and Mucin 5B in A549 ALI cultures as determined by both immunoblotting and quantitative RT-PCR assay. These results suggest that the ALI culture of A549 cells can partially mimic the property of alveolar epithelia, which may be a feasible and alternative model for investigating roles and mechanisms of alveolar epithelia in vitro.

Abstract
Objective To investigate the expressions of chromatin assembly factor 1 subunit A (CHAF1A) and proliferating cell nuclear antigen (PCNA) in cervical squamous cell carcinoma (CSCC) and their clinical implication. Methods Real-time quantitative PCR was performed to detect the mRNA levels of CHAF1A and PCNA in CSCC and corresponding paracancerous tissues. Immunohistochemistry was used to detect the expressions of CHAF1A and PCNA proteins in normal cervical epithelium tissues (NC), cervical intraepithelial neoplasia tissues (CIN), and CSCC. The correlation between CHAF1A and PCNA expressions and the relationship of the two proteins to the clinical pathological features of cervical cancer were analyzed. Results The expressions of CHAF1A and PCNA in CIN and CSCC were significantly higher than those in NC. In addition, CHAF1A and PCNA expressions were positively correlated in the CSCC tissues. Furthermore, overexpression of CHAF1A was significantly associated with the degree of differentiation, tumor size, depth of cancer invasion and HPV infection. Finally, the up-regulated expression of PCNA was correlated with the degree of differentiation, International Federation of Gynecology and Obstetrics (FIGO) grade, lymph node metastasis, depth of cancer invasion and HPV infection. Conclusion CHAF1A and PCNA are highly expressed in CSCC and associated with the malignancy.

Abstract
IL-37, a newly found anti-inflammatory cytokine of the IL-1 family, has both extracellular and intracellular functions. Accumulating evidences indicate that it is also involved in tumor progression. However, the mechanism and its intracellular target are unclear. In this study, clinical data from 84 patients showed that loss or reduced expression of IL-37 in lung adenocarcinoma tissues was significantly associated with tumor metastasis. We further provided evidence that IL-37 inhibited effectively tumor metastasis in vitro and in vivo. Moreover, we uncovered a novel mechanism by which IL-37 suppressed tumor cell migration via its intracellular mature form (amino acids 46-218). Intracellular mature form of IL-37, but not its extracellular form, markedly inhibited migration of multiple kinds of tumor cells through inhibiting Rac1 activation. Mechanistically, intracellular mature IL-37 directly bound to the CAAX motif in the C-terminal hypervariable region of Rac1, and then inhibited Rac1 membrane translocation and subsequent downstream signaling. Our research identifies intracellular mature IL-37 as a novel endogenous inhibitor of Rac1. Given the crucial roles of Rac1 in tumor angiogenesis and metastasis, intracellular mature IL-37 might serve as a potential strategy for the control of Rac1 activity and tumor progression.

Abstract
Objective: To identify the clinical features of mononucleosis caused by co-infection of Epstein-Barr virus (EBV) and cytomegalovirus (CMV) in adult patients. Methods: A total of 103 inpatients with mononucleosis in Peking University Third Hospital from May 2013 to May 2016 were collected as the study subjects.The patients were divided into three groups according to the responsible pathogens: 33 patients infected with EBV and CMV, 53 infected with EBV alone and 17 infected with CMV alone.Furthermore, a case-control study was employed to retrospectively compare the clinical characteristics and prognosis with χ(2,) t or rank tests. Results: The incidences of sore throat, pharynx congestion, tonsil enlargement, tonsil membrane, lymphadenectasis in co-infected patients were statistically lower than those in EBV-infected patients(χ(2)=19.202-25.492, all P<0.05), and were equivalent to those in CMV-infected patients(χ(2)=0.078-4.381, all P>0.05). The levels of alkaline phosphatase, glutamyl transferase, lactic dehydrogenase, white blood cell count and atypical lymphocyte in co-infected patients were statistically lower than those in EBV-infected patients(t/U=3.471-104.629, all P<0.05), and were similar to those in CMV-infected patients(t/U=0.447-24.330, all P>0.05). The levels of alanine aminotransferase and total bilirubin in co-infected patients were equivalent to those in the other two groups(U=1.695, 6.371, both P>0.05). The duration of fever in co-infected patients[(18±9) d] was between EBV alone [(15±7) d] and CMV alone [(21±7) d]infected patients. Conclusions: Co-infection of EBV and CMV is not uncommon.The clinic manifestation of co-infection is more like CMV infection. Liver injury and duration of fever shows no aggravation.

Abstract
OBJECTIVE To detect the levels of serum C-C chemokine ligand 19 (CCL19) in patients with systemic lupus erythematosus (SLE) and to evaluate the correlation between CCL19 expression and clinical features and laboratory parameters, trying to reveal the possible role of CCL19 in the pathogenesis of systemic lupus erythematosus. METHODS The levels of serum CCL19 were measured by enzyme linked immunosorbent assay (ELISA) in 90 patients with SLE and 30 healthy controls. These SLE patients included 75 patients who received treatment with glucocorticoids and disease-modifying anti-rheumatic drug (DMARD) and 15 patients without therapy. The frequencies of peripheral blood B cells and the B cell subsets were assessed in the patients with SLE by flow cytometry. The correlation between the clinical data, laboratory parameters, B cell subset frequencies and serum CCL19 levels were analyzed. Indepen-dent samples t test, paired t test, Pearson and Spearman correlation were used for statistical analyses. RESULTS The levels of CCL19 were markedly higher in the SLE patients without therapy and the patients with therapy than in the health controls[(596.25±409.19) ng/L and (422.90±395.84) ng/L vs. (157.79±125.23) ng/L, all P<0.001]. Serum CCL19 levels in the SLE patients without therapy were higher than the SLE patients who accepted glucocorticoids and DMARD treatment (P<0.05). The levels of serum CCL19 were positively correlated with anti-double stranded deoxyribonucleic acid (dsDNA), anti-nucleosome antibody (AnuA), IgA, IgG and IgM (r=0.38, P=0.007; r=0.332, P=0.029; r=0.519, P=0.007; r=0.461, P=0.018, respectively). Serum CCL19 levels in the SLE patients with photosensitivity, arthritis and secondary Sjögren's syndrome were higher than the SLE patients without photosensitivity, arthritis and secondary Sjögren's syndrome, respectively [(562.25±399.12) ng/L, (565.6±435.24) ng/L and (694.9±531.02) ng/L vs. (394.7±281.42) ng/L, (385.90±325.33) ng/L and (424.8±305.46) ng/L, all P<0.05]. The levels of serum CCL19 were positively correlated with the percentage of CD27-B cells and CD27-IgD-double-negative memory B cells (r=0.519, P=0.007; r=0.461, P=0.018, respectively). However, the levels of serum CCL19 were negatively correlated with the percentage of CD27+ memory B cells and CD27+IgD- switched memory B cells (r=-0.433, P=0.027; r=-0.616, P=0.001, respectively). CONCLUSION The increased serum CCL19 levels in SLE patients were associated with the production of autoantibodies, and CCL19 might be involved in the pathogenesis of SLE by disturbing the homeostasis of B cell subsets.

Abstract
Background Interleukin-17A (IL-17A) is not only an important modulator of inflammatory reactions, but also affects bone metabolism, which is involved in osteogenic differentiation of stem cells. However, the role and mechanism of IL-17A in osteogenic differentiation of bone mesenchymal stem cells (BMSCs) are not fully understood. In this study, we investigated the role and mechanism of IL-17A in osteogenic differentiation of BMSCs. Material/Methods The osteogenic differentiation of BMSCs was induced by osteoblast-induction medium with IL-17A or without IL-17A. The osteogenic differentiation of BMSCs was confirmed by the alkaline phosphatase and alizarin red staining. The lentiviral plasmid was used to construct the sFRP1-shRNA expression vector. The associated osteogenic differentiation marks (RUNX2, ALP, OPN), Wnt signaling pathway inhibitor (sFRP1), and modulators of Wnt signaling pathway (Wnt3, Wnt6) were detected by qRT-PCR and Western blot method. Results The results showed that the addition of IL-17A inhibited osteogenic differentiation of BMSCs. IL-17A induced up-regulated expression of sFRP1 and down-regulated expression of Wnt3 and Wnt6 in BMSCs. In addition, sFRP1-shRNA abolished the inhibition effect of IL-17A in osteogenic differentiation of BMSCs and induced up-regulated expression of Wnt3 and Wnt6 in the Wnt signaling pathway in BMSCs. Conclusions Our findings show that IL-17A inhibits osteogenic differentiation of bone mesenchymal stem cells via the Wnt signaling pathway.

Abstract
Objective: To investigate the significance of extranodal extension of axillary lymph nodes (ALN-ENE) metastases in post-operative primary invasive breast carcinoma of non-specific type. Methods: Six hundred and thirty-eight invasive breast cancer cases confirmed by postoperative pathological examination were collected from January 2006 to December 2008. The relationship of lymph node metastases and ALN-ENE with other lymph node parameters and patient outcome was analyzed. Results: Among 638 cases, 263 (41.2%) showed axillary lymph node metastases. ALN-ENE was present in 91 cases (36.4%). The rate of ALN-ENE increased with pT stage and tumor size. Five-year recurrence-free survival rate (RFS) and 5-year overall survival rate (OS) was 86.6% and 91.2% respectively for ALN-ENE positive group, and both were lower than ALN-ENE negative group (P<0.01). One hundred and forty-nine patients with 1 to 3 positive lymph nodes had a 5-year RFS of 91.9%, and 5-year OS of 92.3%, less than ALN-ENE negative group (P<0.01). Univariate analysis showed ALN-ENE positively correlated with lymph node metastasis. Multivariate analysis suggested that ENE was associated with increased recurrence risk and shortened recurrence-free and overall survival, especially in patients with 1 to 3 positive lymph nodes; and it was an independent prognostic factor (P<0.01). Conclusions: The number of lymph nodes metastases is an important predictor of survival in breast cancer patients. ALN-ENE is an independent risk indicator for recurrence and overall survival. For patients with 1 to 3 metastatic axillary lymph nodes, ALN-ENE could alter the patient's clinical pathologic staging, and therefore it is an independent prognostic factor.

Abstract
Mesenchymal stem cells (MSCs) have been demonstrated to have promising therapeutic benefits for a variety of neurological diseases; however, the underlying mechanisms are poorly understood. Here, we showed that intravitreal infusion of MSCs promoted retinal ganglion cell (RGC) survival in a mouse model of acute glaucoma, with significant inhibition of microglial activation, production of TNF-α, IL-1β, and reactive oxygen species, as well as caspase-8 and caspase-3 activation. In vitro, MSCs inhibited both caspase-8-mediated RGC apoptosis and microglial activation, partly via the action of stanniocalcin 1 (STC1). Furthermore, we found that microRNA-21a-5p (miR-21) and its target, PDCD4, were essential for STC1 production and the neuroprotective property of MSCs in vitro and in vivo. Importantly, miR-21 overexpression or PDCD4 knockdown augmented MSC-mediated neuroprotective effects on acute glaucoma. These data highlight a previously unrecognized neuroprotective mechanism by which the miR-21/PDCD4 axis induces MSCs to secrete STC1 and other factors that exert neuroprotective effects. Therefore, modulating the miR-21/PDCD4 axis might be a promising strategy for clinical treatment of acute glaucoma and other neurological diseases.

Abstract
The aim of this study was to evaluate whether Schisandra chinensis extract (SCE) administration influences chronic unpredictable mild stress (CUMS)-induced depression and cognitive impairment, and explores underlying mechanisms. Sucrose preference test (SPT) and forced swimming test (FST) were used for assessing depressive symptoms, and Y-maze, Morris water maze were used for evaluating cognition processes. The results showed that CUMS (4 weeks) was effective in producing both depression and memory deficits in mice. Additionally, CUMS exposure significantly decreased brain derived neurotrophic factor (BDNF) levels in hippocampus as indicated by ELISA, immunohistochemistry and immunofluorescence assays, accompanied by down-regulated tyrosine kinase receptor B (TrkB)/cAMP-response element binding protein (CREB)/extracellular signal-regulated kinase (ERK) and phosphatidylinositol 3 kinase (PI3K)/ protein kinase B (AKT)/ glycogen synthase kinase-3β (GSK-3β) signaling pathways. Chronic administration of SCE (600 or 1200 mg/kg, i.g.) significantly prevented all these CUMS-induced behavioral and biochemical alterations. It suggested that SCE could improve the depression-like emotional status and associated cognitive deficits in CUMS mice, which might be mediated by regulation of BDNF levels in hippocampus, as well as up-regulating of TrkB/CREB/ERK and PI3K/AKT/GSK-3β pathways.

Abstract
OBJECTIVE To assess the associations between depression and incident cancer risk. STUDY DESIGN Systematic review and meta-analysis. METHODS The Cochrane Library, Web of Science, MEDLINE, and PubMed databases were searched to identify studies. The quality of included studies was assessed using the Newcastle Ottawa Scale. Risk ratios (RRs) were used to measure effect size. A random-effects model was applied to synthesize the associations between depression and cancer risk. A forest plot was produced to visually assess RRs and 95% confidence intervals (CIs). Heterogeneity across studies was assessed using the I-squared statistic. A funnel plot was generated to assess potential publication bias, and Egger's regression was applied to test the symmetry of the funnel plot. RESULTS In total, 1,469,179 participants and 89,716 incident cases of cancer from 25 studies were included. Depression was significantly associated with overall cancer risk (RR = 1.15, 95% CI: 1.09-1.22) and with liver cancer (RR = 1.20, 95% CI: 1.01-1.43) and lung cancer (RR = 1.33, 95% CI: 1.04-1.72). Subgroup analysis of studies in North America resulted in a significant summary relative risk (RR = 1.30, 95% CI: 1.15-1.48). No significant associations were found for breast, prostate, or colorectal/colon cancer. The average Newcastle Ottawa score was 7.56 for all included studies. CONCLUSION Our findings showed a small and positive association between depression and the overall occurrence risk of cancer, as well as liver cancer and lung cancer risks. However, multinational and larger sample studies are required to further research and support these associations. Moreover, confounding factors such as cigarette smoking and alcohol use/abuse should be considered in future studies.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most common and malignant carcinoma worldwide, and the incidence and mortality are increasing rapidly. Immunotherapy targeting programmed death 1/programmed death ligand 1 (PD-L1) signaling has shown prominent clinical effects in treating NSCLC; however, a poor understanding of the associated regulating molecular mechanisms of PD-L1 has become one of the biggest obstacles for further improving efficacy. Bridging integrator-1 (BIN1) can regulate numerous cancer-related molecules to exert multiple tumor-suppressing effects by either interacting or not interacting with c-MYC. In the present study, we observed that there exists a negative correlation between the expression of PD-L1 and BIN1 in NSCLC tissues. The expression levels of BIN1 and PD-L1 were significantly related to the tumor, lymph node and metastasis grade (TNM) stage, invasion range and lymph node metastasis. Simultaneously, for NSCLC patients, the expression statuses of BIN1 and PD-L1 might be independent prognostic factors. Furthermore, the expression of tumor-infiltrating lymphocytes was positively associated with BIN1 expression and negatively related to PD-L1 expression in NSCLC tissues. Importantly, we showed that PD-L1 was under the control of BIN1. In addition, the overexpression of BIN1 could inhibit the c-MYC and epithelial growth factor receptor (EGFR)-dependent PD-L1 expression and reverse the suppressive immuno-microenvironment in vivo. Taken together, our findings indicated that BIN1 restoration in NSCLC could reverse PD-L1-mediated immune escape by inactivating the c-MYC and EGFR/mitogen-activated protein kinase pathways.

Abstract
The aim of this study was to investigate the effects of bufalin on the mammalian target of rapamycin (mTOR/p70S6 kinase (p70S6K) signaling pathway and cell apoptosis in orthotopically transplanted tumors in nude mice. The mice were inoculated with human esophageal squamous cell carcinoma (ESCC) ECA109 cells in order to establish a model of orthotopicall transplanted ESCC tumors. The mice are administered low, medium and high doses of bufalin (0.5, 1.0 and 1.5 mg/kg) or rapamycin, or a combination of both. After the tumors were removed, the mRNA expression levels of mTOR, p70S6K, eukaryotic translation initiation factor 4E-binding protein 1 (4EBP1), cellular inhibitor of apoptosis protein 1 (cIAP1) and caspase-3 were detected by RT-PCR. In addition, we performed western blot analysis and immunohistochemical analysis to determine the protein expression of mTOR, p70S6K, 4EBP1, cIAP1, active caspase-3, Bcl-2 and Bad in the tumor tissue. The results revealed that bufalin exerted a significant anti-tumor effect in the nude mice with ESCC orthotopically transplanted tumors. This was shown by the decrease in the expression of mTOR, p70S6K and 4EBP1, which suggested that bufalin may possibly be used to inhibit tumor growth via the inhibition of the activation of p70S6K and 4EBP1. We also found that bufalin decreased the expression of cIAP1 and Bcl-2, and increased that of active caspase-3 and Bad, thus indicating that bufalin promoted apoptosis. Thus, our findings suggest that bufalin promotes tumor cell apoptosis, and this may be one of the important anti-tumor mechanisms of action of bufalin.
