Abstract
Thirteen previously undescribed iridoids (1-13), together with five known iridoids (14-18) were isolated from the roots and rhizomes of Valeriana jatamansi Jones. Their structures with absolute configurations were elucidated by analysis of MS, NMR, optical rotation and their experimental and calculated electronic circular dichroism spectra. All of the isolated compounds were tested for their protective effects against α-hemolysin-induced cell death in A549 cells. Compounds 14, 16 and 17 showed moderate protective effects, and compounds 15 and 18 showed weak protective effects.

Abstract
Five undescribed guanidine alkaloids, plumbagines HK (1-4) and plumbagoside E (5), as well as five known analogues (6-10) were isolated from the roots of Plumbago zeylanica. Their structures were established by extensive spectroscopic analyses and chemical methods. In addition, 1-10 were accessed their anti-inflammatory activities by measuring nitric oxide (NO) concentrations in LPS-induced RAW 264.7 cells. However, all compounds especially 1 and 3-5 could not inhibit the secretion of NO but significant increase the secretion of NO. The result reminded us that 1-10 may become potential novel immune potentiators.

Abstract
Seven new hexasaccharide resin glycosides, named calysepins I-VII (1-7), with 27-membered rings, were obtained from the aerial parts of Calystegia sepium. Their structures with absolute configuration were established on the basis of spectroscopic data interpretation analysis and the use of chemical methods. They were defined as hexasaccharides composed of one d-quinovose, four d-glucose, and one l-rhamnose unit, and their sugar moieties were partially acylated by (2S)-methylbutanoic acid in 1-7 and (2R,3R)-nilic acid in 1-5 and 7, which mainly differed at the positions of acylation. Additionally, calysepin IV (4) exhibited cytotoxicity against A549 cells with an IC50 value of 5.2 μM.

Abstract
Objective: To explore age-based clinical and immune parameters in Henoch-Schönlein purpura (HSP) to determine clinically useful markers reflecting disease characteristic. Methods: A cohort of 502 patients with HSP were enrolled into this retrospective study to evaluate their clinical and immune data. Results: Majority HSP cases occurred at age ≤14 years and showed significant immune imbalances of ESR, CD3(+) cells, CD4(+) cells, CD3(-)CD16(+)CD56(+) cells, CD4(+)/CD8(+) cells, IgG, IgA, IgM, IgE, complements C3/C4 and ASO in the acute phase. Compared to patients aged >14 years, symptoms of joint were more frequent at disease onset in patients aged ≤14 years (20.8% vs 7.6%, χ(2)=13.547, P<0.001) , and involvement of digestive tract and joint were also more frequent (57.4% vs 33.8%, χ(2)=24.106, P<0.001; 55.9% vs 32.5%, χ(2)=23.768, P<0.001, respectively) , but not for involvement of kidney (21.4% vs 51.3%, χ(2)=42.440, P<0.001) . The patients aged ≤14 years had distinct immune state, reductions of CD3(+) cells, CD4(+) cells and IgG were more frequent than patients aged >14 years, also increase of ASO (33.1% vs 20.0%, χ(2)=6.656, P=0.010) , but not increase of IgA (2.6% vs 39.4%, χ(2)=15.582, P<0.001) . In addition, reduction of IgG and increase of IgE were positively associated with digestive tract involvement (P<0.001, P=0.001, respectively) , reduction of CD3(+)CD4(+) cells and normal IgM were positively associated with joint involvement (P=0.004, P=0.003, respectively) , increase of CD3(+)CD8(+) cells and normal CD3(+) cells were positively associated with kidney involvement (P=0.032, P=0.014, respectively) . Conclusion: HSP showed significant immune imbalance in the acute phase, patients between aged ≤14 and >14 years had distinct clinical and immune characteristic, and abnormal immune parameters were significantly associated with organ involvements.

Abstract
Cross-species transmission of viruses from wildlife animal reservoirs poses a marked threat to human and animal health 1 . Bats have been recognized as one of the most important reservoirs for emerging viruses and the transmission of a coronavirus that originated in bats to humans via intermediate hosts was responsible for the high-impact emerging zoonosis, severe acute respiratory syndrome (SARS) 2-10 . Here we provide virological, epidemiological, evolutionary and experimental evidence that a novel HKU2-related bat coronavirus, swine acute diarrhoea syndrome coronavirus (SADS-CoV), is the aetiological agent that was responsible for a large-scale outbreak of fatal disease in pigs in China that has caused the death of 24,693 piglets across four farms. Notably, the outbreak began in Guangdong province in the vicinity of the origin of the SARS pandemic. Furthermore, we identified SADS-related CoVs with 96-98% sequence identity in 9.8% (58 out of 591) of anal swabs collected from bats in Guangdong province during 2013-2016, predominantly in horseshoe bats (Rhinolophus spp.) that are known reservoirs of SARS-related CoVs. We found that there were striking similarities between the SADS and SARS outbreaks in geographical, temporal, ecological and aetiological settings. This study highlights the importance of identifying coronavirus diversity and distribution in bats to mitigate future outbreaks that could threaten livestock, public health and economic growth.

Abstract
We examined the gene expression profiles of the 5-hydroxytryptamine signaling pathway in the regenerating liver and 8 types of liver cells during rat liver regeneration, and explored expression differences in 5-hydroxytryptamine signaling pathway genes at the level of tissues and cells, as well as the role of the pathway on liver regeneration. Eight types of rat regenerating liver cells were isolated using Percoll density-gradient centrifugation and immunomagnetic bead methods. Rat Genome 230 2.0 Array was used to detect expression changes in 5-hydroxytryptamine signaling pathway genes. The results showed that 26, 47, 8, 21, 16, 19, 22, 27, and 20 genes changed significantly in hepatocytes, biliary epithelial cells, hepatic stellate cells, oval cells, sinusoidal endothelial cells, Kupffer cells, pit cells, dendritic cells, and the regenerating liver, respectively. Synthetic effects of 5-hydroxytryptamine signaling pathway genes in 8 types of liver cells showed that 26 genes were expressed significantly; the expression trends of 10 genes were the same in the regenerating liver, while others were different. Based on the gene expression profiles of the 8 types of liver cells, 5-hydroxytryptamine promoted hepatocyte proliferation through the RAS and STAT3 signaling pathways, proliferation and differentiation of sinusoidal endothelial cells through the STAT3 signaling pathway, and proliferation and apoptosis of pit cells through the AKT3 signaling pathway. There were large differences in genes involved in 5-hydroxytryptamine signaling at the tissue and cellular levels; thus, liver regeneration should be studied in-depth at the cellular level to reveal the molecular mechanism of liver regeneration.

Abstract
The Moon may be considered as the frontier base for the deep space exploration. The spectral analysis is one of the key techniques to determine the lunar surface rock and mineral compositions. But the lunar topographic relief is more remarkable than that of the Earth. It is necessary to conduct the topographic correction for lunar spectral data before they are used to retrieve the compositions. In the present paper, a lunar Sandmeier model was proposed by considering the radiance effect from the macro and ambient topographic relief. And the reflectance correction model was also reduced based on the Sandmeier model. The Spectral Profile (SP) data from KAGUYA satellite in the Sinus Iridum quadrangle was taken as an example. And the digital elevation data from Lunar Orbiter Laser Altimeter are used to calculate the slope, aspect, incidence and emergence angles, and terrain-viewing factor for the topographic correction Thus, the lunar surface reflectance from the SP data was corrected by the proposed model after the direct component of irradiance on a horizontal surface was derived. As a result, the high spectral reflectance facing the sun is decreased and low spectral reflectance back to the sun is compensated. The statistical histogram of reflectance-corrected pixel numbers presents Gaussian distribution Therefore, the model is robust to correct lunar topographic effect and estimate lunar surface reflectance.

Abstract
20 cases of myelodysplastic syndrome (MDS) patients were treated with Yisuikang (YSK) including MDS-RA 17 cases, MDS-RAEB 2 cases, MDS-RAEB-T 1 case. 14 patients were treated with YSK only, 6 cases were treated with both YSK and Western medicine. The result showed that 4 cases were remitted, 5 cases markedly improved, 6 cases improved and 5 cases ineffective, the total effective rate was 75.0%. It was found that YSK was effective in the treatment of MDS-RA or Qi-Blood Deficiency and Yu-Re Syndrome in TCM, while any other types were ineffective. They also found that types of TCM might be correlated with MDS.
