In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

Hyoscyamine 6 beta-hydroxylase (H6H) is the last rate-limiting enzyme directly catalyzing the formation of scopolamine in tropane alkaloids (TAs) biosynthesis pathway. It is the primary target gene in the genetic modification of TAs metabolic pathway. Full-length cDNA and gDNA sequences of a novel H6H gene were cloned from Datura arborea (DaH6H, GenBank accession numbers for cDNA and gDNA are KR006981 and KR006983, respectively). Nucleotide sequence analysis reveals an open reading frame of 1375 bp encoding 347 amino acids in the cDNA of DaH6H, while the gDNA of DaH6H contains four exons and three introns, with the highest similarity to the gDNA of H6H from D. stramonium. DaH6H also exhibited the most identity of 90.5% with DsH6H in amino acids and harbored conserved 2-oxoglutarate binding motif and two iron binding motifs. The expression level of DaH6H was highest in the mature leaf, followed by the secondary root, and with no expression in the primary root based on qPCR analysis. Its expression was inhibited by MeJA. DaH6H was expressed in E. coli and a 39 kD recombinant protein was detected in SDS-PAGE. Comparison of the contents of scopolamine and hyoscyamine in various TAs-producing plants revealed that D. arborea was one of the rare scopolamine predominant plants. Cloning of DaH6H gene will allow more research in the molecular regulatory mechanism of TAs biosynthesis in distinct plants and provide a new candidate gene for scopolamine metabolic engineering.

OBJECTIVETo evaluate clinical therapeutic effect and the safety of pricking blood therapy combined with ultraviolet irradiation for treatment of acute herpes zoster.
METHODSOne hundred and thirty cases were randomly divided into an observation group and a control group, 65 cases in each group. The observation group was treated with pricking blood therapy combined with ultraviolet irradiation. Firstly, the affected parts were heavily taped with a plum-blossom needle and then cupping. After the cup was removed, with the body surface-dividing field method, ultraviolet irradiation was given at the skin injury area and the nerve root area corresponding to paraspinal vertebra, and the control group was treated with Aciclovir and other western medicine. Seven days constituted one course. Their therapeutic effects and adverse reactions were observed.
RESULTSAfter treatment of 7 days, the cured rate of 76.9% and the total effective rate of 90.8% in the observation group were significantly higher than 38.5% and 66.2% in the control group, respectively (both P < 0.01); the incidence rate of post herpetic neuralgia of 3.1% in the observation group was significantly lower than 12.3% in the control group (P < 0.05); after treatment, the scores for pain, rash and sleep decreased significantly in the two groups (all P < 0.01), more significantly decreased in the observation group than in the control group (P < 0.01 or P < 0.05); the pain-relieving time, herpes-stopping time, scab-forming time and the cured time in the cured patients of the observation group were significantly shorter than those in the control group (P < 0.01 or P < 0.05).
CONCLUSIONThe pricking blood therapy combined with ultraviolet irradiation has rapid therapeutic effect, effectively shortens duration of illness, decreases the incidence rate of post herpetic neuralgia and it is a safe remedy for treatment of herpes zoster.

Objective:Accumulating evidences prove that macrophages affect tumor initiation and prognosis. Especially,tumor-associated macrophages (TAMs) are considered to enhance tumor growth,progression,angiogenesis,invasion and metastasis. Furthermore,tumor suppressive microenvironment can " reeducate" and polarize the phenotype and function of TAM. Recently, researchers use different ways to interfere and modify the phenotype and function of macrophages,to improve the recognition, phagocytosis and antigen presentation of macrophage,and enhance its antitumor activity. We will discuss the pro-tumorigenic properties of macrophage and TAM-targeting therapy as a promising novel strategy for tumor immunotherapy.

OBJECTIVETo evaluate the activity of DNA polbeta promoter on p53 gene in salivary adenoid cystic carcinoma (SACC) cells.
METHODSThe luciferase activity was examined and used to evaluate the activity of DNA polbeta promoter on SACC-83 cells. Eukaryotic expression plasmids of p53 gene were constructed and stably transfected into SACC-83 cells. RT-PCR was used to assess the expression of p53 gene. The SACC-83 cells were subjected to the treatments of H2O2, ultraviolet radiation, Bleocin, and affected p53 mRNA and protein level in SACC-83 cells were characterized with RT-PCR and Western blotting.
RESULTSThe result of luciferase activity proved that the activity of DNA polbeta promoter in SACC-83 cells was much higher than that of CMV promoter. The results of RT-PCR suggested that p53 gene with different promoters were all expressed effectively, but the expression efficiency was different. It was greater in DNA polbeta group than in CMV group. After DNA damage, p53 gene expression increased and DNA polbeta promoter could enhance the expression of p53 gene more than CMV promoter. The results of Western blotting indicated that the expression of P53 protein between the two groups did not show any difference.
CONCLUSIONIn SACC cells, the activity of DNA polbeta promoter was increased and DNA polbeta promoter could enhance the expression of p53.
