Abstract: Total RNA was isolated from Siraitia grosvenorii fruit by the method of modified Trizol, according to S. grosvenorii fruit characteristics of rich phenols, polysaccharide, oil and proteins. The OD260/280, OD260/230, RNA integrity (RIN) and yield of the total RNA with this method were 2.01, 2.02, 9.50 and 260 mirog.g-1, respectively. The open reading frame (ORF) of dehydroascorbate reductase (DHAR), named as SgDHAR, was cloned by rapid amplification of cDNA ends (RACE) and RT-PCR method from S. grosvenorii. The GenBank accession number for this gene is KC907731. The SgDHAR gene contains a full-length cDNA of 1,252 bp including ORF of 819 bp and encodes a predicted protein of 272 amino acids. The molecular mass is 30.217 7 kD and the isoelectric point is 8.76. Homology comparison showed that it shared 87% nucleotide sequence homology with Cucumis sativus. Expression patterns using qRT-PCR analysis showed that SgDHAR was mainly expressed in fruit and stem, followed by flower, and was lowest in root, while the expression level was 6.83 times in triploid. T than that in diploid. Therefore, SgDHAR gene may be involved in abortion of triploid seedless S. grosvenorii.

Objective To explore the potential mechanism of Babao Dan on primary liver cancer based on network pharmacology. Methods First, the diethylnitrosamine-induced hepatocellular carcinoma rat（HCC）model was used to observe the effects of Babao Dan. Then, the effective components in Babao Dan were detected by UPLC-MS, and the potential target sites of these effective components were predicted in the Swiss Target Prediction databases, etc. The corresponding target sites for HCC were screened using GeneCards, OMIM and Therapeutic Target Database, and the common target sites between Babao Dan and HCC were obtained after getting the intersection. The protein-protein interaction network was drawn by Cytoscape software and the STRING database, and the key molecules regulating HCC by Babao Dan were screened out. The effective target sites were subjected to GO analysis in the DAVID database and enrichment analysis in the Pathway’s KEGG. Finally, the clinical relevance of key molecules to liver cancer patients was verified by the TCGA database. Results Babao Dan could slow down the tumor development. 851 chemical components were detected in BaBao Dan by UPLC-MS , 9 major active components and 285 target sites were identified. 637 hepatocellular carcinoma-related targets were screened out, and 16 targets of Babao Dan regulating HCC were identified. GO enrichment analysis showed 802 biological processes, 11 cell compositions, and 43 molecular functions, while KEGG pathway enrichment analysis identified a total of 90 pathways. Correlation analysis of TCGA identified three key molecules associated with the survival of liver cancer patients. Conclusion In the primary rat liver cancer model, Babao Dan was found to significantly prolong the survival of cancer-induced rats and reduce tumor burden. The initial prediction of the mechanism by which Babao Dan regulating liver cancer was made through UPLC-MS analysis and network pharmacology methods, indicating that Babao Dan has the characteristics of multi-component, multi-pathway, and multi-target regulation of primary liver cancer, which could provide a reference for further relevant experimental research.

ObjectiveTo predict the potential targets and possible related signaling pathways of Salviae Miltiorrhizae Radix et Rhizoma against bladder cancer （BC） based on network pharmacology and verify the potential molecular mechanism through in vitro cell experiment. MethodActive components of Salviae Miltiorrhizae Radix et Rhizoma were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and BC-related targets were searched from GeneCards and Online Mendelian Inheritance in Man （OMIM）. Via Venny2.1， the potential targets of Salviae Miltiorrhizae Radix et Rhizoma against BC were screened out and the Venn diagram was plotted. Protein-protein interaction （PPI） network was constructed by STRING， followed by Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Gnomes （KEGG） pathway enrichment with DAVID. Cell Counting Kit-8 （CCK-8） assay was employed to detect the inhibitory effect of tanshinone Ⅱ_A （Tan Ⅱ_A）， cryptotanshinone （CPT）， and luteolin （LUT） at different concentration （0， 1， 2， 4， 8， 16， 32 μmol·L^-1） on the proliferation of BC T24 and 5637 cells， propidium iodide （PI） staining to analyze the apoptosis of 5637 cells induced by Tan Ⅱ_A， CPT， and LUT （0， 4， 8 μmol·L^-1）， and Western blotting to detect the regulatory effect of Tan Ⅱ_A （0， 4， 8， 16 μmol·L^-1） on the expression of key target proteins. ResultA total of 65 active components and 39 anti-BC targets of Salviae Miltiorrhizae Radix et Rhizoma were screened out. The anti-BC targets were mainly involved in the KEGG pathways of neuron-ligand-receptor interaction， phosphatidylinositol 3-kinases （PI3K）/protein kinase B （Akt） signaling pathway， epidermal growth factor receptor （EGFR） tyrosine kinase inhibitor resistance， and hypoxia inducible factor （HIF）-1 signaling pathway. As for the CCK-8 assay， compared with the blank group， Tan Ⅱ_A， CPT， and LUT significantly inhibited the proliferation of T24 and 5637 cells， particularly the 5637 cells. The half maximal inhibitory concentration （IC₅₀） of Tan Ⅱ_A on 5637 cells was significantly lower than that of CPT and LUT. Moreover， compared with the blank group， Tan Ⅱ_A， CPT， and LUT all induced the apoptosis of 5637 cells， and the effect followed the order of Tan Ⅱ_A>CPT>LUT （P<0.05）. Western blot showed that Tan Ⅱ_A significantly reduced the expression of EGFR， p-PI3K， and p-Akt in 5637 cells in a concentration-dependent manner compared with the blank group （P<0.05）. ConclusionSalviae Miltiorrhizae Radix et Rhizoma exerts therapeutic effect on BC through multiple components， multiple targets， and multiple pathways. The mechanism is the likelihood that it down-regulates the expression of EGFR， p-PI3K， and p-Akt proteins， thus further inhibits cell proliferation， and induces apoptosis.

Mogrosides and steroid saponins are tetracyclic triterpenoids found in. Squalene synthase (SQS) and cycloartenol synthase (CAS) are key enzymes in triterpenoid and steroid biosynthesis. In this study, full-length cDNAs ofandwere cloned by a rapid amplification of cDNA-ends with polymerase chain reaction (RACE-PCR) approach. ThecDNA has a 1254 bp open reading frame (ORF) encoding 417 amino acids, and thecDNA contains a 2298 bp ORF encoding 765 amino acids. Bioinformatic analysis showed that the deduced SgSQS protein has two transmembrane regions in the C-terminal. Bothandhave significantly higher levels in fruits than in other tissues, suggesting that steroids and mogrosides are competitors for the same precursors in fruits. Combinedprediction and subcellular localization, experiments in tobacco indicated that SgSQS was probably in the cytoplasm or on the cytoskeleton, and SgCAS was likely located in the nucleus or cytosol. These results will provide a foundation for further study ofandgene functions in, and may facilitate improvements in mogroside content in fruit by regulating gene expression.

Traditional Chinese medicine (TCM) is an important part of the treatment of primary liver cancer (PLC) in China; however, the current instructions for the integrative use of traditional Chinese and Western medicine for PLC are mostly based on expert opinion. There is no evidence-based guideline for clinical practice in this field. Therefore, the Shanghai Association of Chinese Integrative Medicine has established a multidisciplinary working group to develop this guideline, which focuses on the most important questions about the use of TCM during PLC treatment. This guideline was developed following the methodological process recommended by the World Health Organization Handbook for Guideline Development. Two rounds of questionnaire survey were performed to identify clinical questions; published evidence was searched; the Grading of Recommendations Assessment, Development and Evaluation approach was used to evaluate the body of evidence; and recommendations were formulated by combining the quality of evidence, patient preferences and values, and other risk factors. The guideline was written based on the Reporting Items for Practice Guidelines in Healthcare tool. This guideline contains 10 recommendations related to 8 questions, including recommendations for early treatment by TCM after surgery, TCM combined with transcatheter arterial chemoembolization for advanced PLC, TCM drugs for external use, and acupuncture and moxibustion therapy.

OBJECTIVETo evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris.

METHODSBlock randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina.

RESULTSThe 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSII and III subgroups (P>0.05), while they were signifificantly better for KA in the CCSI and II subgroups (P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was signifificantly lower in the KA group than in the control group for the CCSII and III subgroups (9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01).

CONCLUSIONSKA is not inferior to NT in the remission of angina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).
