Abstract
Objective: To investigate the effect and mechanisms of picroside Ⅱ on the brain tissue after cerebral ischemia reperfusion(I/R) in rats. Methods: The middle cerebral artery occlusion(MCAO) rat model was established by inserting a monofilament into middle cerebral artery. The experimental rats were treated by injecting picroside Ⅱ intraperitoneally. The modified neurological severity score (mNSS) and body weight were determined before modeling and after reperfusion of 22 h. The cerebral infarct volume was measured by TTC staining and the cerebral water content was measured in rats. At the same time, ROS content and NADPH oxidase activity were detected. The structure of neurons was observed by electron microscope and the mRNA and protein levels of Rac-1 and Nox2 were detected by RT-PCR and Western blotting. Results: After modeling, the mNSS score was significantly increased (12.6±1.3 vs 0, P<0.001), while the body weight was lost (13.3%±2.5% vs 4.9%±0.8%, P<0.01). The cerebral infarct volume increased obviously (33.5%±3.4% vs 0, P<0.001), brain water content increased significantly (81.5%±0.9% vs 77.7%±0.9%, P<0.05) and the structure of neuron was damaged obviously. The protein and mRNA levels of Rac-1 and Nox2 were significantly increased (P<0.05). After treatment with picroside Ⅱ, mNSS score decreased significantly (7.9±0.8 vs 12.6±1.3, P<0.05) and the body weight increased obviously (9.3%±1.1% vs 13.3%±2.5%, P<0.05). The infarct volume of brain was significantly reduced (18.2%±1.9% vs 33.5%±3.4%, P<0.05), brain water content decreased obviously (79.1%±0.7% vs 81.5±0.9%, P<0.05), the morphological structures of neurons was restored, and the expressions of Rac-1 and Nox2 were significantly decreased (P<0.05). Conclusion: It is suggested that picroside Ⅱ could exert antioxidation to protect the brain tissue through inhibiting the expression of Rac-1 and Nox2.

Abstract
A new method of direct precision frequency measurement is proposed in this paper, which uses the clock cursor effect between the sampling clock signal and input signal and ADC (analog to digital converter) quantization error suppression technique in the background of digital measurement with double ADC. On this basis, a precision frequency corrector is designed. Compared with the traditional frequency synthesizer, this device takes the non-standard frequency signal of the crystal oscillator as the reference to realize the standard frequency signal output through the frequency correction function. Meanwhile, the output signal is obviously narrower in range, from 0.0001 Hz to 0.1 Hz. The frequency corrector can also realize the second stability of less than 3 × 10-12 and a small frequency correction of 10-11 orders of magnitude.

Abstract
Objective: To study the clinicopathologic characteristics and immunophenotype of lymphomatoid papulosis(LyP), followed by exon mutation analysis with focus on gene mutations involved in apoptosis pathway and other possible pathogenic genes. Methods: Clinical data analysis and immunohistochemical staining were carried out in 20 cases of LyP. Whole exome sequencing technology was employed in 2 cases of type C of LyP. Results: Of the 20 cases, there were 9 males and 11 females with a median age of 28.6 years. Nineteen patients presented with multiple papules and nodules, and one case presented with only one tumor nodule. Of the fifteen cases with available followed-up data, all were alive (20-155 months). Histologically, the tumors primarily involved the dermis and subcutaneous layer, in which 6 were type A, 3 were type B, 10 were type C and 1 was type D. Main infiltration patterns included wedge-shaped, band-like, sheets and large nodular. Immunohistochemistry showed that most cases expressed CD30 in the large tumor cells. Sixteen cases expressed CD3, 17 cases expressed CD4 and 8 cases expressed CD8. Sixteen cases expressed TIA1. Ten cases expressed GrB and 1 case expressed CD15. All but one case did not expressed CD20. All cases did not express ALK1.A total of 101 common non-synonymous mutations were detected in 2 cases of LyP type C by whole exome sequencing, including 87 missense mutations, 6 missense mutation/frame-shift deletions, 2 missense mutation/nonframe-shift deletions, 5 frame-shift deletions, 1 missense mutations/synonymous mutation. Syndecan-1(SDC1), COL4A1, Laminin-5 were involved in the extracellular matrix receptor pathway. Conclusions: Clinical presentations are crucial for the diagnosis of LyP. LyP has a favorable prognosis. SDC1, COL4A1 and Laminin-5 gene mutations may be associated with tumor recurrence or progression into a higher gradelymphoma.

Abstract
Euphorbia humifusa Willd. (EH), rich in flavonoids, has long been used for the treatment of bacillary dysentery and enteritis in China, and is known to have antioxidant, hypotensive and hypolipidemic properties. However, the vasorelaxant effect of total flavonoids of EH (TFEH) and action mechanisms are not clearly defined yet. The aim of the present study was to investigate the effects of TFEH on the vascular tension and its underlying mechanisms. Experiments were performed in rat thoracic aorta using the organ bath system. TFEH (0.01 - 100 μg/ml) caused a concentration-dependent vasorelaxation, which was dependent on a functional endothelium, and were significantly attenuated by inhibitors of endothelial NO synthase, its upstream signaling pathway, PI3K/Akt, and soluble guanylate cyclase, but not by blockade of KCa channel, KATP channel, cyclooxygenase, muscarinic and β-adrenergic receptors. Extracellular Ca2+ depletion, and pre-treatment with modulators of the store-operated Ca2+ entry channels, Gd3+ and 2-aminoethyl diphenylborinate, significantly attenuated the TFEH-induced vasorelaxation. Our findings suggest that TFEH elicit vasorelaxation via endothelium-dependent NO-cGMP pathway through activation of PI3K/Akt- and Ca2+-eNOS-NO signaling. Further, it is suggested that TFEH-induced activation of the NO-soluble guanylate cyclase-cGMP-protein kinase G signaling relaxes vascular smooth muscle cells through an inhibition of the L-type Ca2+ channel activity.

Abstract
We report on a field induced domain evolutionary procedure in the anisotropic Nd-Dy-Fe-Co-B/MgO/Fe multilayers by using first-order-reversal-curves and magnetic force microscopy. Different reversal behaviors and domain sizes are found in well coupled and decoupled multilayers by changing the thickness of the spacer layer. The competition between dipolar magnetostatic energy and Zeeman energy is evaluated by in-field observation throughout nucleation and annihilation processes. In addition, lithography-patterned arrays of soft Fe disks onto a continuous Nd-Dy-Fe-Co-B hard-magnetic layer are designed. By decreasing the applied field, it is found that magnetization orientations of the Fe disk and Nd-Dy-Fe-Co-B layer are aligned parallel. In the decoupled disk, although the out-of-plane magnetization orientations are observed, the orientation of the domains in the Fe disk is random. Furthermore, it is found that a stronger anisotropy of the Nd-Dy-Fe-Co-B layer decreases the interaction length. Our results provide a new understanding of anisotropic nanocomposite magnets with long-ranged magnetic interactions.

Abstract
Objective:The aim of this study is to investigate the effect of gonadotropin releasing hormone (GnRH) on suppressing cell viability, apoptosis, migrationg and invationg of human nasopharyngeal carcinoma cells CNE2. Method:Nasopharyngeal carcinoma tissues and postnasal catarrh tissues were collected, the expression of GnRH positive cells and GnRH mRNA were detected by immunohistochemical staining and qRT-PCR. The human nasopharyngeal carcinoma CNE2 cells and immortalized nasopharyngeal epithelial cell line NP69 were cultured in vitro, and the expression of GnRH positive cells and GnRH mRNA were detected by immunohistochemical staining and qRT-PCR. The CNE2 cells were treated with GnRH with various concentrations 0 (Blank group), 10⁻², 10⁻¹, 10⁰ nmol/L. The effects of GnRH on the viability, apoptosis, migration and invasion of CNE2 cells were detected by cell Counting Kit (CCK-8), flow cytometry, wound healing assay and transwell chamber assay in vitro. Result:The expression of GnRH positive cells and GnRH mRNA in nasopharyngeal carcinoma tissues were markedly down regulated than postnasal catarrh tissues (P<0.05). The expression of GnRH positive cells and GnRH mRNA in CNE2 cells were markedly down regulated than NP69 cells (P<0.05). Compared with blank group, GnRH can significantly inhibite the cell viability cells, apoptosis, migration and invasive ability (P<0.05 or P<0.01). Conclusion:GnRH significantly inhibited the cell viability, apoptosis, migration and invasive ability of CNE2 cells.

Abstract
Objective: To observe the expression of three microenvironment related prognostic factors, i. e. programmed death 1 (PD-1), forkhead box protein 3(FOXP3) and colony-stimulating factor 1 receptor(CSF-1R) protein in classical Hodgkin's lymphoma (CHL) patients, and to explore the correlation between the protein expression and the prognosis of the patients. Methods: A total of 45 cases of CHL patients, who had been admitted to the Tianjin Medical University Cancer Institute and Hospital and Chinese PLA General Hospital from February 2005 to August 2010 were analyzed, including clinical features, prognostic factors, and treatment regimens. CHL patients' specimens were collected and the expression of PD-1, FOXP3, and CSF-1R proteins analyzed by immunohistochemical staining. Epstein-Barr virus encoded mRNA (EBER) was detected by in situ hybridization analysis. The relationship between the protein expression of PD-1, FOXP3 and CSF-1R and the patients' outcome was analyzed with clinical and follow-up data. Survival analysis was performed by Kaplan-Meier method, the Cox proportional hazard model was used to perform multivariate analysis. Results: In this cohort of 45 CHL patients, PD-1 positive was found in 7 cases (15.6%), FOXP3 high expression in 23 cases (51.1%), CSF-1R positive in 18 cases (40.0%). In the univariate analysis, the expression of FOXP3 and CSF-1R, International Prognostic Index (IPI) score, Ann Arbor stage and EBER were related with the patients' 5-year overall survival (OS); IPI score, the expression of FOXP3 and EBER were related with the patients' 5-year progress-free survival (PFS). Multivariate analysis indicated that CSF-1R protein expression was the independent prognostic factor affecting the patients' 5-year OS(HR: 8.918, P=0.020), and FOXP3 protein expression was the independent prognostic factor affecting the patients' 5-year PFS (HR: 0.122, P<0.001). And EBV was an independent prognostic factor of PFS and OS in the CHL patients. Conclusion: Microenvironment related prognostic factors FOXP3, CSF-1R and EBV may be independent prognostic factors of CHL and this study may provide novel strategies for targeted therapy of CHL.

Abstract
MuDR exhibits the highest transposition activity and insertional mutagenesis frequency in Mutator (Mu) family. If we isolate the MuDRinsertionspecific flanking sequences (MuDRFs), it will be crucial for using Mu elementmediated mutants. The MuDRTAILPCR system was constructed and optimized using a combination of MuDRTIRnested specific primers and 12 arbitrary degenerate (AD) primers, modified reaction system and procedure and mutant DNA templates of 87 genotypes from M2 or M2:3 families created by crossing the W22::Mu line (active MuDR donor parent) from the UniformMu population with the Zong31 (Z31) line (recipient parent). Here 129 different MuDRFs were acquired by MuDRTAILPCR, accounting for 86.60 % of the total mutantspecific agarose gel bands. In addition, we confirmed the authenticity of the nonredundant flanking sequence amplifications. The amplified nonredundant flanking sequences accounted for 65.12 % of the total MuDRFs, and 88.00 % of the nonredundant MuDRFs were inserted inside the genes. These results show that the MuDRTAILPCR system that we developed can be used for specifically isolating MuDRFs.

Abstract
Objective:To explore the relationship between variation of hemoglobin saturation and related respiratory events in patients with obstructive sleep apnea and hypopnea syndrome (OSAHS).Method:According to the SaO₂, the respiratory events were divided into two groups, followed or not followed the second events (SRE and N-SRE). Four features were extracted from SaO₂ and compared within groups under SRE versus N-SRE, and comparisons were also developed between moderate patients and severe patients.Result:ΔSaO₂, max, the duration and Dvmax was significantly higher in SRE than N-SRE (P< 0.01), while Nadir was significantly lower in SRE than N-SRE (P< 0.01). There was also significant difference in the blood oxygen index between moderate and severe patients. The change of SaO₂ is correlated with the ventilation restoration. The results also suggest that the severity of the patient's condition will affect the change of SaO₂ related indicators. Conclusion:This study provides information on the further study of ventilation restoration. Moreover, this study may provide a possible solution for the treatment of OSAHS.

Abstract
Panax japonicus C.A. Meyer, a perennial herb belonging to the Araliaceae ginseng genus, is one of the seven rare and endangered Chinese medical herbs. By cloning the SS segment, the expression vectors pCXSN-PjSS and pCXSN-antiPjSS were constructed and introduced into Agrobactria LBA4404, which is used for engineering bacteria. Polymerase chain reaction (PCR) showed that the PjSS, antiPjSS, and Hyg were integrated in Nicotiana tabacum. Reverse transcription-PCR indicated that the PjSS was transcribed into mRNA in N. tabacum and was highly expressed, while the antiPjSS was not expressed. Detection of Ginsenoside Re content showed that transgenetic N. tabacum can increase the content of Ginsenoside Re and that anti-transgenetic N. tabacum decreased the content of Ginsenoside Re.

Abstract
Recent genetic evidence suggests a robust association of the CARD14 single nucleotide polymorphism rs11652075 (c.C2458T/p.Arg820Trp) and other rare mutations in this gene with psoriasis. To assess whether combined data support the relationship between CARD14 rs11652075 and susceptibility to this disease, we conducted a meta-analysis. PubMed (MEDLINE), EMBASE, Web of Science, and the Cochrane Library were searched for relevant papers published in English. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effect models. Heterogeneity between studies was assessed using the Cochran's Q and I2 statistics. A total of five published studies, including 32,807 psoriasis patients and 45,458 controls, met our inclusion criteria and were included in the meta-analysis. The pooled OR of the association between the minor allele of this polymorphism and psoriasis was 0.877 (95%CI = 0.834-0.922; P < 0.001). In a stratified analysis, pooled ORs relating to European and Asian ancestry were 0.883 (95%CI = 0.822-0.948) and 0.872 (95%CI = 0.812-0.936), respectively. Those calculated for studies with case sample sizes above and below 1000 were 0.912 (95%CI = 0.870- 0.956) and 0.824 (95%CI = 0.734-0.924), respectively. No publication bias was present, and the exclusion of any single dataset did not substantially alter the corresponding pooled ORs. Due to the limited data available regarding clinical classification of cases and genotypes, subgroup stratification by clinical type was not performed. Our results demonstrate a significant association between the CARD14 rs11652075 polymorphism and psoriasis.

Abstract
The aggregation behavior and interactions of yak milk protein were investigated after heat treatments. Skim yak milk was heated at temperatures in the range of 65 to 95°C for 10 min. The results showed that the whey proteins in yak milk were denatured after heat treatment, especially at temperatures higher than 85°C. Sodium dodecyl sulfate-PAGE analysis indicated that heat treatment induced milk protein denaturation accompanied with aggregation to a certain extent. When the heating temperature was 75 and 85°C, the aggregation behavior of yak milk proteins was almost completely due to the formation of disulfide bonds, whereas denatured α-lactalbumin and β-lactoglobulin interacted with κ-casein. When yak milk was heated at 85 and 95°C, other noncovalent interactions were found between proteins including hydrophobic interactions. The particle size distributions and microstructures demonstrated that the heat stability of yak milk proteins was significantly lowered by heat treatment. When yak milk was heated at 65 and 75°C, no obvious changes were found in the particle size distribution and microstructures in yak milk. When the temperature was 85 and 95°C, the particle size distribution shifted to larger size trend and aggregates were visible in the heated yak milk.

Abstract
To better understand the cloud condensation nuclei (CCN) activation capacity of aerosol particles in different pollution conditions, a long-term field experiment was carried out at a regional GAW (Global Atmosphere Watch) station in the Yangtze River Delta area of China. The homogeneity of aerosol particles was the highest in clean weather, with the highest active fraction of all the weather types. For pollution with the same visibility, the residual aerosol particles in higher relative humidity weather conditions were more externally mixed and heterogeneous, with a lower hygroscopic capacity. The hygroscopic capacity (κ) of organic aerosols can be classified into 0.1 and 0.2 in different weather types. The particles at ~150 nm were easily activated in haze weather conditions. For CCN predictions, the bulk chemical composition method was closer to observations at low supersaturations (≤0.1%), whereas when the supersaturation was ≥0.2%, the size-resolved chemical composition method was more accurate. As for the mixing state of the aerosol particles, in haze, heavy haze, and severe haze weather conditions CCN predictions based on the internal mixing assumption were robust, whereas for other weather conditions, predictions based on the external mixing assumption were more accurate.
