Abstract
The performance of an interband cascade laser based laser heterodyne radiometer (LHR) is demonstrated in ground-based solar occultation mode. High-resolution (0.0033 cm-1) transmission spectra near 3.53 μm were obtained for simultaneous atmospheric observations of H2O and CH4. Combined with the preprocessed measurement data (acquired at Hefei, China, on June 21th 2016), an optimal estimation method based retrieval algorithm is developed for data retrieval and error analysis. By considering the corrected atmospheric parameters, vertical profiles of H2O and CH4 are retrieved. Finally, the measured total column abundance and XCH4 were calculated to be 1.87 ± 0.02 ppm and 1.88 ± 0.02 ppm, respectively. The interband cascade laser-based laser heterodyne radiometer that is demonstrated in this manuscript has high potential for use in the development of compact, robust, and unattended LHR for spacecraft, airborne or ground-based atmospheric sensing.

Abstract
Simple low rate pre-activation effectively prolonged the cycle life of Li-O2 batteries with MWNT cathodes in a 1 M LiClO4/DMSO electrolyte from 55 to 290 cycles, and the ultimate capacity and rate performance were also significantly enhanced, attributed to reconstructed homogeneous and compact SEI layers on the Li anodes by pre-activation.

Abstract
Plant-derived flavonoids contain large amount of compounds with pharmacological effects. In this study, we showed the compound Kaempferol to have robust antiviral activity against bovine herpesvirus 1 (BoHV-1) replication in vitro. Kaempferol at a concentration of 100 μmol/l completely inhibited viral replication in MDBK cells. It mainly affects the viral replication at the post-entry stages. The inhibition of Akt signaling is a potential mechanism underlying the antiviral effect of Kaempferol. In addition, at a concentration of 25 and 50 μmol/l Kaempferol could significantly reduce the expression of inflammatory mediators such as tumor necrosis factor alpha (TNF-α), interleukin-8 (IL-8) and macrophage inflammatory protein 1 alpha (MIP-1α) in human promonocytic U937 cells-derived macrophages (dU937) in response to lipopolysaccharides (LPS) stimulation. Overall, our results indicated that Kaempferol provides a potent protection against BoHV-1 infection and LPS-induced inflammatory response.

Abstract
Prostate-specific antigen is not useful for detection of prostate cancer in Chinese men. The major problems in prostate cancer patients are overdiagnosis and overtreatment. The objective of the study was to test the hypothesis that targeted biopsy is an accurate diagnostic tool for prostate cancer detection than standard biopsy in Chinese men.Total, 998 patients whom multiparticulate multiparametric magnetic resonance imaging had revealed at least 1 lesion in the prostate were included in a cohort. Patients were subjected to magnetic resonance imaging (MRI)/ultrasound (US) fusion-guided biopsy followed US-guided biopsy. Benefits of a diagnostic test were evaluated by decision curve analysis. Patients who were diagnosed as having prostate cancer by either of biopsies were subjected to radical prostatectomies followed by whole-mounted pathology (n = 578). Spearman rank correlation was performed between the biopsy results and the subtype of prostate cancer at 99% of confidence level.With respect to whole-mounted pathology, for US-guided biopsy, MRI/US fusion-guided biopsy, and combined data of both biopsies, sensitivities were 0.973, 0.983, and 0.973 and accuracies were 0.837, 0.91, and 0.917, respectively. MRI/US fusion-guided biopsy (P = .165) and combined data of both biopsies (P = .182) had the same specificity to whole-mount pathology. However, a US-guided biopsy had not the same specificity to whole-mount pathology (P = .0003). Decision-making zones for radical prostatectomy of different biopsies were in the order of combined data of both biopsies >MRI/US fusion-guided biopsy >US-guided biopsy.Only the targeted biopsy is recommended for the diagnosis of prostate cancer.

Abstract
Bovine herpesvirus 1 (BoHV-1) infection causes substantial economic losses to the cattle industry worldwide. So far, the isolation of BoHV-1 field virus has not been reported in China. Here, for the first time we report that two isolates of BoHV-1 designated as NJ16-1 and NJ16-2 were obtained from semen samples from breeding bulls in China. Typical cytopathic effect in MDBK cells, detection of viral protein VP16 in western blot analysis, PCR detection of BoHV-1 gB gene proved BoHV-1 infection and subsequent nucleotide sequence analysis showed a 99% identity with BoHV-1 Cooper strain. These results suggest that these isolated viruses are BoHV-1.

Abstract
Calcium is one of the most prominent second messengers in eukaryotic cells. The involvement of calcium signaling in bovine herpesvirus 1 (BoHV-1) replication was not yet reported. In this study, we revealed that the L-type Ca2+ calcium channel blocker, Verapamil and store-operated calcium channel blocker, 2-aminoethyl diphenylborinate (2-APB) inhibited BoHV-1 replication in MDBK cells at the post-entry stages, and the Na+/Ca²+ exchanger inhibitor, N-arachidonoyl glycine exchanger (NAGly) interfered with the viral entry process. NAGly also effected the phosphorylation of PLCγ-1 at Ser1248, which corroborated our previous findings, that PLCγ-1 is important for BoHV-1 entry. Collectively, these results suggest that diverse calcium channels are employed by BoHV-1 for efficient replication.

Abstract
The present study aimed to determine whether the expression of transient receptor potential channel 5 (TRPC5) protein is altered in spermatozoa of patients with varicocele-associated asthenozoospermia. TRPC5 expression in spermatozoa was determined by polymerase chain reaction and western blotting analyses, and indirect immunofluorescence was used for identification and immunolocalization of the TRPC5 channel in human sperm. Sperm motility and superoxide dismutase (SOD) activity were also determined with a computer-assisted semen analysis system and assay kit, respectively. Compared with levels in control subjects, it was identified that TRPC5 protein expression, SOD activity and cellular motility in the sperm of patients with varicocele-associated asthenozoospermia were reduced (P<0.001). Furthermore, the expression of TRPC5 was positively correlated with sperm motility (r=0.781, P<0.001) and SOD activity (r=0.933, P<0.001), indicated by partial correlation analysis. The present study may provide a novel target for the study and treatment of varicocele-associated asthenozoospermia.

Abstract
BACKGROUND AND PURPOSE Although flow diverters have been reported with favorable clinical and angiographic outcomes in various literatures, randomized trials determining their true effectiveness and safety are still in lack. The Parent Artery Reconstruction for Large or Giant Cerebral Aneurysms Using the Tubridge Flow Diverter (PARAT) trial was designed to evaluate the safety and efficacy of the Tubridge flow diverter in the treatment of large or giant aneurysms in comparison with Enterprise stent-assisted coiling. MATERIALS AND METHODS This prospective, multicenter, randomized trial was conducted at 12 hospitals throughout China. Enrolled adults with unruptured large/giant intracranial aneurysms were randomly assigned (1:1) to receive either Enterprise stent-assisted coiling or Tubridge flow diverter implantation. The primary end point was complete occlusion at 6-month follow-up, while secondary end points included technical success, mortality, target vessel-related stroke, aneurysm bleeding, in-stent stenosis, parent artery occlusion, and the frequency of all adverse events. RESULTS Among 185 enrolled subjects, 41 withdrew before procedure initiation. Overall, 82 subjects underwent Tubridge implantation, and 62 subjects were primarily treated with stent-assisted coiling. The results of 6-month follow-up imaging included complete occlusion rates of 75.34% versus 24.53% for the Tubridge and stent-assisted coiling groups, respectively, with a calculated common odds ratio of 9.4 (95% confidence interval, 4.14-21.38; P < .001). There was a higher, nonsignificant frequency of complications for Tubridge subjects. Multivariate analysis showed a decreased stroke rate at the primary investigational site, with a marginal P value (P = .051). CONCLUSIONS This trial showed an obviously higher rate of large and giant aneurysm obliteration with the Tubridge FD over Enterprise stent-assisted coiling. However, this higher obliteration rate came at the cost of a nonsignificantly higher rate of complications. Investigational site comparisons suggested that a learning curve for flow-diverter implantation should be recognized and factored into trial designs.

Abstract
Oxytocin has an important function in breastfeeding via its role in the milk ejection reflex and in attachment and bonding processes. Genetic factors account for a significant part of the individual differences in breastfeeding behavior. OXT and OXTR have been proposed as gene candidates for breastfeeding. Previous studies have focused on certain single-nucleotide polymorphisms (SNPs) within these genes, finding null or inconsistent results. The present study analyses the associations between a wide coverage of polymorphisms in OXT and OXTR and breastfeeding duration from 2 large and independent unselected samples comprising a total of 580 and 2112 female twin mothers from the Murcia Twin Registry (Spain) and QIMR Berghofer Medical Research Institute (Australia), respectively. A total of 19 SNPs in OXT and 137 in OXTR SNPs were covered in both samples. Effects of the OXT and OXTR polymorphisms on breastfeeding duration were calculated by means of linear regression controlling for age at survey time, educational level, interaction between age and educational level and principal components of genetic ancestry. The analyses were conducted independently in the 2 samples and also meta-analyzed. Although some SNPs were associated at an alpha level of .05 with breastfeeding, they did not survive multiple testing correction. We conclude that SNPs within or nearby OXT and OXTR are unlikely to have large effects on breastfeeding behavior.

Abstract
BACKGROUND AND PURPOSE Childhood arteriopathies are rare but heterogenous, and difficult to diagnose and classify, especially by nonexperts. We quantified clinical and imaging characteristics associated with childhood arteriopathy subtypes to facilitate their diagnosis and classification in research and clinical settings. MATERIALS AND METHODS The Vascular Effects of Infection in Pediatric Stroke (VIPS) study prospectively enrolled 355 children with arterial ischemic stroke (2010-2014). A central team of experts reviewed all data to diagnose childhood arteriopathy and classify subtypes, including arterial dissection and focal cerebral arteriopathy-inflammatory type, which includes transient cerebral arteriopathy, Moyamoya disease, and diffuse/multifocal vasculitis. Only children whose stroke etiology could be conclusively diagnosed were included in these analyses. We constructed logistic regression models to identify characteristics associated with each arteriopathy subtype. RESULTS Among 127 children with definite arteriopathy, the arteriopathy subtype could not be classified in 18 (14%). Moyamoya disease (n = 34) occurred mostly in children younger than 8 years of age; focal cerebral arteriopathy-inflammatory type (n = 25), in children 8-15 years of age; and dissection (n = 26), at all ages. Vertigo at stroke presentation was common in dissection. Dissection affected the cervical arteries, while Moyamoya disease involved the supraclinoid internal carotid arteries. A banded appearance of the M1 segment of the middle cerebral artery was pathognomonic of focal cerebral arteriopathy-inflammatory type but was present in <25% of patients with focal cerebral arteriopathy-inflammatory type; a small lenticulostriate distribution infarct was a more common predictor of focal cerebral arteriopathy-inflammatory type, present in 76%. It remained difficult to distinguish focal cerebral arteriopathy-inflammatory type from intracranial dissection of the anterior circulation. We observed only secondary forms of diffuse/multifocal vasculitis, mostly due to meningitis. CONCLUSIONS Childhood arteriopathy subtypes have some typical features that aid diagnosis. Better imaging methods, including vessel wall imaging, are needed for improved classification of focal cerebral arteriopathy of childhood.

Abstract
Porcine postweaning multisystemic wasting syndrome (PMWS) caused by porcine circovirus type 2 (PCV2) is a disease causing severe economic losses annually worldwide to the pig industry. PCV2 infection was first reported in China in 2000, and currently has three major genotypes, PCV2a, b and d, circulating in this country. To further elucidate the origin and prevalence of PCV2 in China, 123 clinical pig tissue samples collected in 25 provinces between 1990 and 1999 were analysed by PCV2-specific PCR, resulting in identification of 23 PCV2 strains collected between 1996 and 1999. Phylogenetic analysis based on the nucleotide sequences of open reading frame 2 (ORF2) showed that 20 of the 23 grouped within PCV2a, while the remaining three strains formed an independent clade, so far unreported and therefore named PCV2f. This genotype shared lower sequence identity with other known genotypes. This study provides further understanding of the genetic diversity and evolution of PCV2 and has tracked PCV2 infection in China back to 1996 rather than 2000.
