In order to provide a scientific basis for the establishment of a Daphnes Cortex medicinal material fungus library and the screening of endophytic fungi that promote the growth of Daphnes Cortex and increase the content of daphnetin, we used Illumina high-throughput testing technology to analyze 9 Daphnes Cortex samples from Gansu and Shanxi provinces. A total of 632 766 valid sequences were obtained, including 348 OTUs, 4 phyla, 20 classes, 48 orders, 108 families, 154 genera, and 208 species. The sum of the first 3 fungal genera account for more than 65% of the total abundance, with the highest reaching 98.4%.

The study is aimed to ensure the quality and safety of medicinal plants by using ITS2 DNA barcode technology to identify Corydalis boweri, Meconopsis horridula and their close related species. The DNA of 13 herb samples including C. boweri and M. horridula from Lhasa of Tibet was extracted, ITS PCR were amplified and sequenced. Both assembled and web downloaded 71 ITS2 sequences were removed of 5. 8S and 28S. Multiple sequence alignment was completed and the intraspecific and interspecific genetic distances were calculated by MEGA 5.0, while the neighbor-joining phylogenetic trees were constructed. We also predicted the ITS2 secondary structure of C. boweri, M. horridula and their close related species. The results showed that ITS2 as DNA barcode was able to identify C. boweri, M. horridula as well as well as their close related species effectively. The established based on ITS2 barcode method provides the regular and safe detection technology for identification of C. boweri, M. horridula and their close related species, adulterants and counterfeits, in order to ensure their quality control, safe medication, reasonable development and utilization.

BACKGROUNDGrowing preclinical evidence shows that zoledronic acid (ZOL) exhibits direct antitumor activity in various cancer cell lines. However, the cytotoxic effects of ZOL on human hepatocellular carcinoma (HCC) cells have not been established. In the present study, we investigated the effect of ZOL on HCC both in vitro and in vivo.
METHODSCytotoxicity and cell cycles were assessed with Sulforhodamine B colorimetric assay and flow cytometry. Expression levels of cell cycle phase-linked proteins were examined. The effect of ZOL on HCC in vivo was explored based on H22-subcutaneous injection (s.c.) and H22-intraperitoneal injection (i.p.) mice model.
RESULTSZOL inhibited the growth of SK-HEP-1 and H22 cells and induced S-phase arrest through downregulating cdc2 protein and upregulating cyclin A. It inhibited the growth of s.c tumors, and increased the survival of both H22-s.c. and H22-i.p. mice in vivo.
CONCLUSIONZOL inhibits growth of HCC cells in vitro and in vivo.

Vascular endothelial growth factor (VEGF) is one of the main angiogenic cytokines and plays an important role in the development of human solid tumors. However, it is not clarified whether VEGF governs the progress of the chronic myelogenous leukemia (CML). This study is to estimate VEGF expression in the bone marrow cells from normal and adult CML patients and various leukemic cell lines. Reverse transcription-polymerase chain reaction (RT-PCR) was used for detection of VEGF mRNA. VEGF concentrations in the cell cultural supernatant and the plasma from normal and CML patient bone marrows were determined by enzyme linked immunosorbent assay (ELISA). VEGF mRNA was positive in 67 of 72 cases of bcr/abl(+) CML patient bone marrow cells (93.1%), in 5 of 10 CML patients post Allo-BMT bone marrow cells (50%), and in 6 of 10 normal bone marrow cells (60%), the expression rate of VEGF mRNA in CML patients bone marrow cells was higher than that in CML patients post Allo-BMT and normal bone marrow cells. VEGF mRNA also expressed in the HL-60, K562, CEM, KG1a, NB4, and Nalm6 cells, but not in the Jurkat cells. The mean VEGF concentration in the plasma (380.6 pg/ml) from 22 untreated CML patients was 9 folds higher than that from 9 CML patients post Allo-BMT (38.0 pg/ml). The mean VEGF concentration in the cultural supernatant (499.8 pg/ml) of 17 newly diagnosed CML bone marrows was 2.5-folds higher than that in 11 normal donors (141.3 pg/ml). The CML marrow cells secrete more VEGF than normal marrow cells do. Our results suggest that the abnormality of VEGF transcription and translation expression may play an important role in the development of CML.

Objective To analyze and compare the outcomes of esophageal carcinoma treated with simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT) and late course boost intensity-modulated radiation therapy (LCB-IMRT).Methods We retrospectively analyzed 128 patients with esophageal squamous cell carcinoma who were treated with SIB-IMRT or LCB-IMRT at the fifth department of radiation oncology in our hospital,from January 2009 to August 2015.Propensity score matching analysis was used to balance the variables differences in the two groups.Survival,failure patterns and toxicities were observed and compared between the two groups.Results one hundred and eleven patients were finally included after propensity scores matching.The 1-,3-and 5-year local control rates and survival rates were 83.6% vs.81.7%,70.8% vs.46.3% and 66.0% vs.38.2% in the whole group,respectively.The 1-,3-and 5-year local control rates of SIB-IMRT and LCB-IMRT group were 81.6% vs.88.0%,72.3% vs.67.6% and68.5% vs.60.8%,respectively (P>0.05).The 1-,3-and 5-year survival rates of SIB-IMRT and LCB-IMRT group were 81.3% vs.82.4%,51.7% vs.36.7% and 45.8% vs.26.7%,respectively (P > 0.05).There was no statistical difference between the two group in ≥ grade 3 toxicities (P > 0.05).There were 40 (36.0%) patients result in treatment failure in all.The treatment failure rates in SIB-IMRT and LCB-IMRT group were 33.8% (26/77) vs.41.2% (14/34),respectively (P > 0.05).The local failure accounted for 65.0% (26/40) of all treatment-related failures.Conclusions The toxicities of esophageal squamous cell carcinoma treated with SIB-IMRT and LCB-IMRT have no significant differences and were well tolerated.There were no significant differences in local control rates and survival rates between the two groups.However,SIB-IMRT had better trend than LCB-IMRT.Given SIB-IMRT's convenient manipulation,it could be a better choice in the treatment of advanced esophageal carcinoma.

OBJECTIVELcrV is an important component for the development of a subunit vaccine against plague. To reduce immunosuppressive activity of LcrV, a recombinant LcrV variant lacking amino acids 271 to 326 (rV270) was prepared by different methods in this study.
METHODSA new strategy that produced non-tagged or authentic rV270 protein was designed by insertion of rV270-thrombin-hexahistidine fusion gene into the vector pET24a, or by insertion of hexahistidine-enterokinase-rV270 or hexahistitine-factor Xa-rV270 fusion gene into the vector pET32a. After Co(2+) affinity chromatography, a purification strategy was developed by cleavage of His tag on column, following Sephacryl S-200HR column filtration chromatography.
RESULTSRemoval of His tag by thrombin, enterokinase and factor Xa displayed a yield of 99.5%, 32.4% and 15.3%, respectively. Following Sephacryl S-200HR column filtration chromatography, above 97% purity of rV270 protein was obtained. Purified rV270 that was adsorbed to 25% (v/v) Al(OH)₃ adjuvant in phosphate-buffered saline (PBS) induced very high titers of antibody to rV270 in BALB/c mice and protected them (100% survival) against subcutaneous challenge with 10⁶ CFU of Y. pestis virulent strain 141.
CONCLUSIONThe completely authentic rV270 protein can be prepared by using enterokinase or factor Xa, but they exhibited extremely low cleavage activity to the corresponding recognition site. Thrombin cleavage is an efficient strategy to prepare non-tagged rV270 protein and can be easily operated in a large scale due to its relatively low cost and high cleavage efficacy. The recombinant rV270 can be used as a key component to develop a subunit vaccine of plague.
