Entanglement signatures for quantum synchronization with single-ion phonon laser.

The entanglement properties of quantum synchronization, based on a single-ion phonon laser subjected to an external drive, have been studied. It is found that the maximum value of steady-state entanglement between the ion's internal and external states occurs near the noiseless boundary from synchronization to unsynchronization, accompanied by noticeable oscillatory behaviors during the corresponding time evolution of entanglement. In addition, the later time dynamics of entanglement also indicates the occurrence of frequency entrainment, as evidenced by the strong consistency between the bending of the observed frequency and the emergence of Liouvillian exceptional points (LEPs) in the first two eigenvalues of the Liouvillian eigenspectrum. Moreover, the emergence of LEPs, which is intimately associated with frequency entrainment, should be widely observed in quantum synchronization and can be explored in LEPs-based applications.

All oxide based flexible multi-folded invisible synapse as vision photo-receptor.

All oxide-based transparent flexible memristor is prioritized for the potential application in artificially simulated biological optoelectronic synaptic devices. SnOx memristor with HfOx layer is found to enable a significant effect on synaptic properties. The memristor exhibits good reliability with long retention, 104 s, and high endurance, 104 cycles. The optimized 6 nm thick HfOx layer in SnOx-based memristor possesses the excellent synaptic properties of stable 350 epochs training, multi-level conductance (MLC) behaviour, and the nonlinearity of 1.53 and 1.46 for long-term potentiation and depression, respectively, and faster image recognition accuracy of 100% after 23 iterations. The maximum weight changes of -73.12 and 79.91% for the potentiation and depression of the synaptic device, respectively, are observed from the spike-timing-dependent plasticity (STDP) characteristics making it suitable for biological applications. The flexibility of the device on the PEN substrate is confirmed by the acceptable change of nonlinearities up to 4 mm bending. Such a synaptic device is expected to be used as a vision photo-receptor.

(±)-Gentiovarisin A and gentiovarisin B, unusual secoiridoid dimer skeletons from gentiopicroside.

Gentiana scabra, a famous traditional Chinese medicine (TCM), has been documented in Chinese Pharmacopoeia for the treatment of hepatitis. Its index component gentiopicroside could not be detected in the decoction, which suggested that the quality control of the TCM with this ingredient needs attention. The transformed products were obtained from gentiopicroside, mimicking the traditional process of G. scabra. Further investigation of the heat-transformed products yielded two secoiridoid dimers, gentiovarisin A (1) and B (2), with an unprecedented 6/6/6/6/6-fused pentacyclic skeletons. Their structures were elucidated by extensive spectroscopic analyses and single-crystal X-ray diffraction analysis, and the absolute configurations of 1 were confirmed as (+)-1 and (-)-1 by ECD method. Plausible transformation pathways of the isolates were also proposed. Compounds 1 and 2 exhibited in vitro hepatoprotective activity similar to gentiopicroside, while (+)-1 displayed a more potent hepatoprotective activity than N-Acetyl-L-cysteine.

Effects of astragalus polysaccharides on improvement of liver and kidney injury and regulation of intestinal flora structure in cadmium-exposed rats / 中国药理学通报

Aim To investigate the effects of astragalus polysaccharides on the improvement of liver and kidney injury and the regulation of intestinal flora structure in cadmium exposed rats. Methods Rats exposed to cadmium were established by intraperitoneal injection of CdCl2. After continuous intragastric administration of astragalus polysaccharides for five weeks, urine, liver, kidney and feces were collected. The cadmium residues in urine, liver and kidney were detected by Graphite Furnace Atomic absorption spectrometry, the pathological changes of liver and kidney were observed by HE staining, and Illumina PE250 sequencing and bioinformatics software were used to analyze the structure of intestinal flora. Results After intraperitoneal injection of CdCl2, the accumulation of cadmium in urine, liver and kidney increased significantly, some liver and kidney cells showed pathological damage such as swelling, necrosis and inflammatory cell infiltration. Chao, ace and shannon indexes decreased significantly, while simpson index increased significantly. The number of OTU decreased. And the abundance of Ruminococcus, Bacteroides, Flavonifractor, Roseburia and Elusmicrobium decreased significantly, but Lactobacillus, that of Lachnospiracea_incertae_sedis, Parasutterella, Clostridium XlVb, Clostridium XI, Integinimonas and Fusobacterium increased significantly. Compared with the normal control group, the differences was statistically significant(P<0.05 or P<0.01). After intragastric administration of astragalus polysaccharides, cadmium accumulation in urine, liver and kidney decreased significantly, liver and kidney cell damage alleviated, and inflammatory cell infiltration reduced. Chao, ace and shannon index increased markedly, and simpson index decreased significantly. OTU number increased. And the bundance of Prevotella, Bacteroides, Parasutterella, Elismicrobium and Barnesiella raised significantly, that of Ruminococcus, Oscillibacter, Flavonifractor, Clostridium XlVa, Roseburia, Lactobacillus, Ruminococcus2, Lachnospiracea_incertae_sedis, Clostridium IV, Clostridium XlVb, Clostridium XI and integinimonas decreased significantly, which was statistically significant compared with the group exposed to cadmium alone(P<0.05 or P<0.01).

Pochonia chlamydosporia Isolate PC-170-Induced Expression of Marker Genes for Defense Pathways in Tomatoes Challenged by Different Pathogens.

Pochonia chlamydosporia is a fungal parasite of nematode eggs. Studies have shown that some strains of Pochonia chlamydosporia can promote plant growth and induce plants' systemic resistance to root-knot nematodes by colonizing in their roots. This study aimed to verify the effect of the PC-170 strain on tomato growth and systemic resistance. Split-root experiments were conducted to observe the systemic resistance induced by PC-170. To explore the defense pathway that was excited due to the colonization by PC-170, we tested the expression of marker genes for defense pathways, and used mutant lines to verify the role of plant defense pathways. Our results showed that PC-170 can colonize roots, and promotes growth. We found a role for jasmonic acid (JA) in modulating tomato colonization by PC-170. PC-170 can activate tomato defense responses to reduce susceptibility to infection by the root-knot nematode Meloidogyne incognita, and induced resistance to some pathogens in tomatoes. The marker genes of the defense pathway were significantly induced after PC-170 colonization. However, salicylic acid (SA)- and jasmonic acid (JA)-dependent defenses in roots were variable with the invasion of different pathogens. Defense pathways play different roles at different points in time. SA- and JA-dependent defense pathways were shown to cross-communicate. Different phytohormones have been involved in tomato plants' responses against different pathogens. Our study confirmed that adaptive JA signaling is necessary to regulate PC-170 colonization and induce systemic resistance in tomatoes.

Acanthus ilicifolius is an excellent mangrove plant. In this study, the complete chloroplast genome of A. ilicifolius, a salt tolerant plant of Acanthaceae, was generated. The length of chloroplast genome is 150,758 bp, in which the large-single copy region (LSC) is 82,963 bp, the small-single copy (SSC) region is 17,191 bp, and a pair of inverted repeat (IRa and IRb) regions is 25,302 bp. The chloroplast genome contains 128 genes, including 84 protein-coding genes, eight rRNA genes, and 36 tRNAs genes, with a total GC content of 38%. Phylogenetic analysis showed that A. ilicifolius was closely related to A. ebracteatus, both species belonged to Acanthus genus.

Sweritranslactone D, a hepatoprotective novel secoiridoid dimer with tetracyclic lactone skeleton from heat-transformed swertiamarin.

Swertia mileensis, known as Qing-Ye-Dan (QYD), has been documented in Chinese Pharmacopoeia to cure hepatitis. Interestingly, its announced main active component, swertiamarin, could not be detected in the decoction, which indicated that the efficacy of QYD might be attributed to heat-transformed products of swertiamarin (HTPS). Further investigation on HTPS led to the isolation of sweritranslactone D (1), a novel secoiridoid dimer possessing a tetracyclic lactone skeleton, with better hepatoprotective activity than N-acetyl-L-cysteine in vitro.

Establishment of an induced pluripotent stem cell line from a patient with hereditary transthyretin amyloidosis carrying transthyretin (TTR) mutation p.Phe53Val.

Hereditary transthyretin amyloidosis (ATTR) is an autosomal dominant rare disease caused by heterozygous mutations in the TTR gene, which encodes depolymerized transthyretin deposited in several organs. An induced pluripotent stem cell (iPSC) line of ATTR was generated from peripheral blood mononuclear cells of a 28 years old male patient carrying the TTR mutation p.Phe53Val. We used non-integrated episomal vectors to achieve the reprogramming of PBMCs, and further proved pluripotency by expression of typical stemness surface markers, gene expression of pluripotency genes and the pathological evidence of teratoma forming three germ layers in vivo. This iPSC line is a useful cellular model for screening potential therapeutic targets and studying the pathogenic mechanism of disease.

Entropy Exchange and Thermodynamic Properties of the Single Ion Cooling Process.

A complete quantum cooling cycle may be a useful platform for studying quantum thermodynamics just as the quantum heat engine does. Entropy change is an important feature which can help us to investigate the thermodynamic properties of the single ion cooling process. Here, we analyze the entropy change of the ion and laser field in the single ion cooling cycle by generalizing the idea in Reference (Phys. Rev. Lett. 2015, 114, 043002) to a single ion system. Thermodynamic properties of the single ion cooling process are discussed and it is shown that the Second and Third Laws of Thermodynamics are still strictly held in the quantum cooling process. Our results suggest that quantum cooling cycles are also candidates for the investigation on quantum thermodynamics besides quantum heat engines.

Ghost imaging normalized by second-order coherence.

Towards improvements in the quality of reconstructed images, the errors in the point spread function of a ghost imaging system caused by a limited number of samplings and imperfect illumination are discussed. We propose an algorithm by normalizing with the second-order coherence of the illumination field, with which the errors caused by imperfect illumination can be reduced, such as non-uniform spatial distribution of the average intensity, spatially varying profile of the second-order degree of coherence, or power fluctuation.

Severe Hyperthyroidism-Heart Failure-Severe Liver Injury:Report of One Case and Literature Review / 中国医学科学院学报

Severe hyperthyroidism can cause the injuries of multiple organs including heart and liver and ultimately be fatal. A 26-year-old young woman admitted to Peking Union Medical College Hospital for severe hyperthyroidism due to irregular use of anti-thyroid drugs. She had heart failure,atrial fibrillation,and severe liver damage at admission. Anti-thyroid drugs were then actively used to treat the primary disease,along with interventions to correct heart failure and control atrial fibrillation. Severe total bilirubin elevation was found during the treatment, which was resolved after the use of glucocorticoid and liver-protective therapy. The patient was regularly followed up after discharge,and the clinical manifestations were good.

Genotype-phenotype relationship in a large cohort of osteogenesis imperfecta patients with COL1A1 mutations revealed by a new scoring system / 中华医学杂志(英文版)

BACKGROUND@#Osteogenesis imperfecta (OI), a heritable bone fragility disorder, is mainly caused by mutations in COL1A1 gene encoding α1 chain of type I collagen. This study aimed to investigate the COL1A1 mutation spectrum and quantitatively assess the genotype-phenotype relationship in a large cohort of Chinese patients with OI.@*METHODS@#A total of 161 patients who were diagnosed as OI in Department of Endocrinology of Peking Union Medical College Hospital from January 2010 to December 2017 were included in the study. The COL1A1 mutation spectrum was identified by next generation sequencing and confirmed by Sanger sequencing. A new clinical scoring system was developed to quantitatively assess the clinical severity of OI and the genotype-phenotype relationship was analyzed. The independent sample t-test, analysis of variance, Mann-Whitney U-test, Chi-squared test, Pearson correlation, and multiple linear regression were applied for statistical analyses.@*RESULTS@#Among 161 patients with OI, 32.9% missense mutations, 16.8% non-sense mutations, 24.2% splice-site mutations, 24.8% frameshift mutations, and 1.2% whole-gene deletions were identified, of which 38 variations were novel. These mutations led to 53 patients carrying qualitative defects and 67 patients carrying quantitative defects in type I collagen. Compared to patients with quantitative mutations, patients with qualitative mutations had lower alkaline phosphatase level (296 [132, 346] U/L vs. 218 [136, 284] U/L, P = 0.009) and higher clinical score (12.2 ± 5.3 vs. 7.4 ± 2.4, P < 0.001), denoting more severe phenotypes including shorter stature, lower bone mineral density, higher fracture frequency, more bone deformity, vertebral compressive fractures, limited movement, and dentinogenesis imperfecta (DI). Patients would not present with DI if the glycine substitutions happened before the 79th amino acid in triple helix of α1 chains.@*CONCLUSIONS@#This presented distinctive COL1A1 mutation spectrum in a large cohort of Chinese patients with OI. This new quantitative analysis of genotype-phenotype correlation would be helpful to predict the prognosis of OI and genetic counseling.

Simultaneous determination of three chemical compounds in embryonic parenchyma cells and endocarp stone cells of Arctii Fructus at five different growth stages by UFLC-MS/MS / 药学学报

In this study, we accurately collected the embryonic parenchyma cells and endocarp stone cells of Arctii Fructus at five different growth stages by laser microdissection. Quantitative analyse of caffeic acid, arctiin and arctigenin in these cells were performed using ultra-fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS). The results showed that a large amount of arctiin was produced and accumulated in embryonic parenchyma cells from the late flowering stage to mature stage, while much lower content of arctiin was produced and accumulated in endocarp stone cells at these stages. It suggested that the biosynthetic pathways of arctiin were different in embryonic parenchyma cells from endocarp stone cells of Arctii Fructus. Arctigenin was found to be produced and accumulated in both embryonic parenchyma cells and in endocarp stone cells from the late flowering stage to mature stage, but it reached a peak in endocarp stone cells at late flowering stage, then decreased slowly. The concentration of arctigenin was far less than that of arctiin regardless of embryonic parenchyma cells or endocarp stone cells. These results have validated the new method for analysis of dynamic accumulation of arctiin in Arctii Fructus by UFLC-MS/MS with frozen sections and microdissection.

Imaging through scattering layers exceeding memory effect range with spatial-correlation-achieved point-spread-function.

We propose to measure intensity transmission matrices or point-spread-function (PSF) of diffusers via spatial-correlation, with no scanning or interferometric detection required. With the measured PSF, we report optical imaging based on the memory effect that allows tracking of moving objects through a scattering medium. Our technique enlarges the limited effective range of traditional imaging techniques based on the memory effect, and substitutes time-consuming iterative algorithms by a fast cross-correlation deconvolution method to greatly reduce time consumption for image reconstruction.

Detecting fast signals beyond bandwidth of detectors based on computational temporal ghost imaging.

Measurement of fast signal is getting more and more important in many fields. In this paper, we propose to detect a temporal signal based on the idea of computational ghost imaging (GI), which can greatly reduce requirements on bandwidth of detectors. In experiments, we implement retrieving of a temporal signal with time scale of 50ns using a detector of 1kHz bandwidth, which is much lower than the requirement on bandwidth of detector according to information theory. The performance of our technique are also investigated under different detection bandwidths.

Genistein Improves the Major Depression through Suppressing the Expression of miR-221/222 by Targeting Connexin 43

OBJECTIVE: Recent studies have indicated the possibility that genistein may improve depression via regulating the expression of miR-221/222. This study is to explore whether genistein could improve depression by altering miR-221/222 levels and investigate the possible mechanisms involved in the improvement effect of genistein. METHODS: The animal model of depression was established through unpredictable chronic mild stress. Nest building test and splash test were adapted to evaluate the effects of genistein on depressive symptoms in mice. qRT-PCR and western blot analysis were used to detect the expression of miR-221/222 and connexin 43 (Cx43) in the prefrontal cortex of the mice. In vitro, U87-MG astrocytes were treated with genistein and the expression of miR-221/222 and Cx43 was measured. The dual-luciferase reporter assay was used to verify whether Cx43 was a direct target of miR-221/222. RESULTS: The behavioral tests showed that genistein could significantly reduce depression symptoms of mice, and this remission was not affected by gender. Genistein in vivo and in vitro could reduce increased levels of miR-221 and miR-222 in the prefrontal cortex of depressed mice, while upregulate Cx43 expression. Dual-luciferase reporter assay suggested Cx43 was directly regulated by miR-221/222 in astrocytes. CONCLUSION: Genistein can play its antidepressant effect through down-regulating miR-221/222 by targeting Cx43.

Study on high throughput sequencing identification of Fructus Arctii and five counterfeit species mix power / 中国中药杂志

Fructus Arctii is a traditional Chinese medicine. The main counterfeit species are the seeds of Arctium tomentosum, Onopordum acanthium, Silybum marianum, Saussurea costus, Amorpha fruticosa. Traditional identification methods or molecular barcoding techniques can identify Fructus Arctii and its counterfeit species. However, the identification of the mixture of it and its spurious species is rarely reported. In this paper, we sequenced the ITS2 sequences of Fructus Arctii and 5 kinds of spurious species mix powder by high-throughput sequencing to identify the mixed powder species and providing new ideas for the identification of Fructus Arctii mix powder. The total DNA in mixed powder was extracted, and the ITS2 sequences in total DNA was amplified. Paired-end sequencing was performed on the DNA fragment of the community using the Illumina MiSeq platform. The sequence was analyzed by the software FLASH, QIIME and GraPhlAn etc. The results showed that the high quality ITS2 sequences of 39910 mix samples were obtained from the mixed samples, of which the total ITS2 sequence of the samples genus was 34 935. Phylogenetic analysis showed that the samples contained Fructus Arctii, A. tomentosum, O. acanthium, S. marianum, S. costus and A. fruticosa. Using ITS2 sequences as DNA barcodes, high-throughput sequencing technology can be used to detect the Fructus Arctii and its spurious specie in mixed powder, which can provide reference for the quality control, safe use of medicinal materials of Fructus Arctii and the identification of mixed powder of traditional Chinese medicine.
