Abstract
Three new diterpenoids, named nematocynine A-C (1-3), together with twelve known compounds (4-15) were isolated from the aerial part of Euphorbia nematocypha Hand.-Mazz (Hereinafter referred to E. nematocypha). Their structures were elucidated by detailed spectroscopic analysis and comparison with literature data. In addition, all the compounds were tested for their anti-candida albicans activities used alone or in combination with fluconazole against sensitive strain and resistant strain in vitro. Wherein only compound 11 shows weak activity against candida albicans resistant strain (MIC50 = 128.15 μg/mL) when used alone. Compounds 1, 4, 7, 8, 9, 10, 12, 13 and 15 in combination with fluconazole showed potent anti-fungal activities (MIC50 = 15 ± 5 μg/mL, FICI = 0.05 ± 0.04) against the Candida albicans resistant strain SC5314-FR. The synergistic effects were weaker against the Candida albicans resistant strain SC5314-FR when the compounds 2, 3, 5 and 14 were combined with fluconazole (FICI = 0.16 ± 0.06).

Abstract
BACKGROUND Pepsinogen C (PGC) is expressed in chief cells, fundic mucous neck cells, and pyloric gland cells of gastric epithelium and also in breast, prostate, lung, and seminal vesicles. METHODS We explored the clinicopathological and prognostic significances of PGC mRNA using pathological and bioinformatics analyses. We generated PGC knockout and PGC-cre transgenic mice to observe the effects of PGC deletion and PTEN abrogation in PGC-positive cells on gastric carcinogenesis. Finally, we observed the effects of altered PGC expression on aggressive phenotypes by CCK8, Annexin V staining, wound healing and transwell assays and analyzed the partner proteins of PGC using co-IP (co-immunoprecipitation) and double fluorescence staining. RESULTS PGC mRNA level was inversely correlated with the T and G stage and a short survival of gastric cancer (p < 0.05). PGC protein expression was negatively linked to lymph node metastasis, dedifferentiation, and low Her-2 expression of gastric cancer (p < 0.05). No difference in body weight or length was evident between wild-type (WT) and PGC knockout (KO) mice (p > 0.05), but PGC KO mice had a shorter survival than WT mice (p < 0.05). No gastric lesions were observed in the mucosa of the granular stomach in PGC KO mice, which displayed lower frequency and severity of gastric lesion than in WT mice after treated with MNU. Transgenic PGC-cre mice showed high cre expression and activity in the lung, stomach, kidney, and breast. Gastric cancer and triple-negative lobular breast adenocarcinoma were found in PGC-cre/PTENf/f mice with two previous pregnancies and breast feeding, but breast cancer was not seen in transgenic mice exposed to either estrogen or progesterone, or those with two previous pregnancies and no breast feeding. PGC suppressed proliferation, migration, invasion, and induced apoptosis, and interacted with CCNT1, CNDP2 and CTSB. CONCLUSION PGC downregulation was seen in gastric cancer, but PGC deletion resulted in resistance to chemically-induced gastric carcinogenesis. PGC expression suppressed the proliferation and invasion of gastric cancer cells possibly by interacting with CCNT1, CNDP2 and CTSB. Spontaneous triple-negative lobular adenocarcinoma and gastric cancer were seen in PGC-cre/PTENf/f mice, and the breast carcinogenesis was closely linked to pregnancy and breast feeding, but not to single exposure to estrogen or progesterone, or pregnancy. Limiting either pregnancy or breast feeding might help to prevent hereditary breast cancer.

Abstract
Fourteen undescribed seco-type diterpenoids, named nudifloids A-N, together with ten known analogs, were isolated from the leaves of Callicarpa nudiflora. Nudifloids A-N had a characteristic 3,4-seco-labdane-type diterpenoid skeleton, whereas nudifloids A-C and K-N were 3,4-seco-norditerpenoids. Nudifloid A was the first example of a 3,4-seco-12,13,14,15,16-quartnor-labdane diterpenoid, with a seven-membered lactone ring formed through esterification between C-3 and C-11. Nudifloids B and C were a pair of highly modified 3,4-seco-labdane nor-diterpenoid epimers, of which C-2 and C-18 were cyclized together to form a cyclohexene fragment. The structures of these undescribed diterpenoids were established by spectroscopic analysis and reference data. The anti-inflammatory activity of diterpenoids in rich yield was evaluated by analyzing the inhibition of lipopolysaccharide plus nigericin-induced pyroptosis in J774A.1 cells. Nudifloids D and E exhibited prominent anti-NLRP3 inflammasome activity, with IC50 values of 1.80 and 1.59 μM, respectively. Cell permeability assays revealed that nudifloid D inhibited pyroptosis, which could ameliorate inflammation by blocking the activation of the NLRP3 inflammasome.

Abstract
Five unknown labdane diterpenoids Stevelins A-E (1-5), three known labdane diterpenoids (6-8) and three labdane norditerpenoids (9-11) were isolated from the Stevia rebaudiana. The structures were determined primarily via NMR spectroscopic data and HR-ESI-MS experiments. X-ray crystallography using CuKα radiation was used to determine the absolute configurations of 1, and the absolute configurations of 2-5 were deduced by electronic circular dichroism (ECD) calculations. The potential anti-atherosclerosis activities of all compounds were evaluated by measuring their inhibitory effects on the macrophage foam cell formation. As a result, most isolated compounds could significantly inhibit oxidized low-density lipoprotein (ox-LDL)-induced macrophage foam cell formation, which suggests that these compounds may be promising candidates in the treatment for atherosclerosis.

Abstract
Keratoconus is an ectatic corneal disorder and characterized by central and/or inferior temporal corneal thinning in a cone shape. Studies have shown that its pathogenesis is related to changes in tissue proteins, enzymes, immune functions and specific genes, but the exact pathogenesis has not been clearly clarified yet. Hormones such as sex hormones have been found to be associated with keratoconus. This review aims to summarize and analyze the research progress of the effect of hormones on keratoconus and its mechanism, so as to explore the role of hormones in the early diagnosis of keratoconus and find new targets in the treatment of keratoconus, providing reference for clinical work.

Abstract
bHLH (basic helix-loop-helix) transcription factors play important roles in the abiotic stress response in plants, but their characteristics and functions in tartary buckwheat (Fagopyrum tataricum), a flavonoid-rich cereal crop with a strong stress tolerance, have not been fully investigated. Here, a novel bHLH gene, designated FtbHLH3, was isolated and characterized. Expression analysis in tartary buckwheat revealed that FtbHLH3 was mainly induced by polyethylene glycol 6000 (PEG6000) and abscisic acid (ABA) treatments. Subcellular localization and a yeast one-hybrid assay indicated that FtbHLH3 has transcriptional activation activities. Overexpression of FtbHLH3 in Arabidopsis resulted in increased drought/oxidative tolerance, which was attributed to not only lower malondialdehyde (MDA), ion leakage (IL), and reactive oxygen species (ROS) but also higher proline (Pro) content, activities of antioxidant enzymes, and photosynthetic efficiency in transgenic lines compared to wild type (WT). Moreover, qRT-PCR analysis indicated that the expression of multiple stress-responsive genes in the transgenic lines was significantly higher than in WT under drought stress. In particular, the expression of AtNCED, a rate-limiting enzyme gene in ABA biosynthesis, was increased significantly under both normal and stress conditions. Additionally, an ABA-response-element (ABRE) was also found in the promoter regions. Furthermore, the transgenic Arabidopsis lines of the FtbHLH3 promoter had higher GUS activity after drought stress. In summary, our results indicated that FtbHLH3 may function as a positive regulator of drought/oxidative stress tolerance in transgenic Arabidopsis through an ABA-dependent pathway.

Abstract
Mudsnails and sediments from an electronic waste recycling region in South China were chosen to study the polybrominated diphenyl ethers (PBDEs) bioavailability of mudsnail in different ambient levels. Significant (p < 0.05) correlations of biota-sediment accumulation factor (BSAF) versus the reciprocal of PBDE concentration in sediment (1/Sed) occurred in all quantitative PBDE congeners except BDE-209, showed that the BSAFs of PBDEs in mudsnails were increased with reciprocal increasing ambient levels. The BDE-183 correlation of mudsnail versus sediment (r = 0.580) was much lower than the correlation of BDE-209 versus BDE-183 in mudsnails (r = 0.812), indicated the main source of BDE-183 in mudsnails was from the debromination of higher brominated PBDEs.

Abstract
Dongting Lake is the second largest freshwater lake in China. Technical sodium pentachlorophenate (Na-PCP) had been sprayed since 1960s to control the spread of snailborne schistosomiasis up to the middle of 1990s. As one of the by-products of Na-PCP, polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) may enter the environment. It has been reported that the concentrations of PCDD/Fs in sediments in Dongting Lake were 130-891 pg I-TEQ g(-1) in 1995. High toxicity of sediment to exposed microorganisms and fish may be risk on environment. In order to determine the present levels of the contamination, eight sediment samples from Dongting Lake were analyzed for PCDD/Fs using HRGC-HRMS. Total I-TEQ values for these samples were at a ranged of 0.7-11 pg g(-1), with a mean value of 4.5 pg g(-1). The results show that PCDD/Fs concentrations of contemporary sediment have declined since 1995. Certain PCDD/F congeners as well as OCDD, typical for Na-PCP, predominated in lake sediment indicating that the using of PCP-Na is the main source of PCDD/Fs in the lake. These variations in levels can reflect changes in PCDD/F sources to the environment over time.

Abstract
Polybrominated diphenyl ethers (PBDEs) in leaves and soil from typical e-waste polluted area in South China were investigated. The concentrations (ng/g dry weight) of PBDE congeners and summation operatorPBDE of five leaf samples were much lower than those in soil sample. The general patterns of summation di-BDEs to summation hepta-BDEs percentage distribution in leaf samples were similar to those of the soil sample, except the percentage of BDE209 which were lower than in soil. The percentages of summation di-BDEs to summation hepta-BDEs in soil were in the range of those in leaf samples. The results showed that the contamination of PBDEs in the leaf samples had good correlation with the soil around them.

Abstract
Endoplasmic reticulum stress-mediated apoptosis plays an important role in the destruction of pancreatic beta-cell, and contributes to the development of type 1 diabetes. The chaperone molecule, glucose regulated proteins 78 (GRP78), is required to maintain ER function during toxic insults. In this study, we investigated the effect of GRP78 on the beta-cell apoptosis. We first measured GRP78 protein expression in different phase of streptozotocin-affected beta-cell by immunoblotting analysis. An insulinoma cell line, NIT-1, transfected with GRP78 was established, named NIT-GRP78, and used to study apoptosis, which was induced by streptozotocin or inflammatory cytokines. Apoptosis of NIT-1 or NIT-GRP78 cells was detected by flow cytometry, the transcription of C/EBP homologous protein (CHOP) was monitored by real-time PCR, the concentration of nitric oxide and the activity of superoxide dismutase were measured by colorimetric method. We found that, in comparison to NIT-1 cells, NIT-GRP78 cells responded to the streptozotocin or cytokines treatments with decreased concentration of nitric oxide, but increased activity of superoxide dismutase. In addition, the level of CHOP was also decreased in the NIT-GRP78 cells, which may mediate the resistance of the GRP78 overexpressed NIT-1 cells from apoptosis. Finally, we found that NIT-GRP78 cells were also more resistant than NIT-1 cells to cytotoxic T lymphocyte (CTL) specific killing detected by flow cytometry through target cells expressing green fluorescent protein cultured with effector cells and finally stained with propidium iodide. The data suggest that modulating GRP78 expression could be useful in preventing pancreatic beta-cell from the immunological destruction in type 1 diabetes individuals.

Abstract
OBJECTIVE To investigate the effect of exogenous p16 on Cyclin D1, CDK4 and pRb, and to explore the mechanism of the growth suppression of p16 in nasopharyngeal carcinoma cell lines. METHODS The curve of cell growth rate in three kinds of HNE1, # 3-2 and # 4-2 cell lines was analyzed and their double time was compared. Then the distribution of the cell cycle was detected by flow cytometry. The expression of p16 and the effect of exogenous p16 expression on CDK4, Cyclin D1 and pRb are studied by means of Western Blot. RESULTS As compared with HNE1, # 3-2 and # 4-2 showed a longer double time(23.4 h vs 28.8 h, 31.2 h). # 4-2 showed a significant accumulation of cells in G0/G1 phase(P < 0.01) and decreasing in S phase(P < 0.05) while HNE1 and # 3-2 had no obvious difference(P > 0.05). Cyclin D1 expression was upregulated in # 4-2 but downregulated in # 3-2 by exogenous expressed p16. No obvious difference on CDK4 expression was found. Hypophosphorylated pRb was detected in three cell lines. The expression was stronger in # 4-2, and # 3-2 than that in HNE1 and Hela. Hyperphosphorylated pRb was also detected in HNE1. CONCLUSION Exogenous p16 expression may arrest cell cycle in G0/G1 phase and suppress cell growth. The major mechanism is not to regulate the level of the expression of CDK4. There might be a threshold in p16 regulating Cyclin D1 expression. However, the final result contributes to the inhibition of pRb phosphorylation.
