摘要：A plant fermentation was carried out by Yeast and Lactobaccilli against fermented black turmeric, Kaempferia parviflora (FBT). These materials were proved by as safe in animal safety experiment. We tried to investigate changes of immune-competent cells that commonly utilized FBT, including after administration of immno-suppressed animals, the effects by FBT on the regulated effect on the cells were evaluated. Our results showed that FBT augmented the level of lymphocytes in number, while FBT regulated the level of granulocytes in both number and function. In our clinical study with 20 healthy volunteers, granulocyte and lymphocyte ratio suggesting their constitution as neutral in peripheral blood were increased significantly 30 days after the administration of FBT in rodents, and compromised host was prepared with cancer chemotherapeutic agent (Mytomycin-C). Our observations showed against intracellular parasite, and that FBT augmented intercellular pathogen through humoral immunity. We discussed the significance and mechanism of FBT on the level of leukocyte subsets in number and function that were considered to be potential indicators for the activation of the compromised host. We also proposed an idea that FBT exhibited tonic effects via activating complement components. The evidences were shown by immune-electrophoretic method. Moreover, we tried to access further to the anti-oxidative activities of this FBT. This modification brought to the significant lift up for antibody producing cells and anti-oxidative activity for phagocytic cells.

摘要：A plant material consisted by Family Poaceae was fermented by Yeast and Lactobaccilli (U-164). This material was proved by as safe in animal safety experiment for oral administration. In order to prove the effect of U-164 against physiological function, the animal and human trials were set up to look into mainly leukocyte functions. In animal experiment, anti-oxidative effect and antibody response in immune-compromised host and diabetes meritus were made up. For human use, peripheral lymphocyte in number and subset ratio were followed up to one month after administration. In order to understand its effect, human complement component analysis was made by immune-electrophoresis. Our results showed that U-164 augmented the level of lymphocytes, while U-164 down regulated the level of granulocytes. In our clinical study with 19 healthy volunteers, granulocyte and lymphocyte ratio was obtained as neutral in peripheral blood being increased significantly 30 days after the ingestion of U-164. In experimental animal study, the compromised host as well as normal animal was administered with cancer chemotherapeutic agent (Mytomycin-C). Our observations showed against antibody producing cell, this material recovered the antibody production in the host compromising the immure responsiveness. We also proposed an idea that U-164 exhibited tonic effects via activating complement components. Moreover, we tried to access further to the anti-oxidative activities of this U-164. This modification brought to the significant lifted up for anti-oxidative activity for phagocytic cell.

摘要：This article proves the existence of a hyper-precise global numerical meta-architecture unifying, structuring, binding and controlling the billion triplet codons constituting the sequence of single-stranded DNA of the entire human genome. Beyond the evolution and erratic mutations like transposons within the genome, it’s as if the memory of a fossil genome with multiple symmetries persists. This recalls the “intermingling” of information characterizing the fractal universe of chaos theory. The result leads to a balanced and perfect tuning between the masses of the two strands of the huge DNA molecule that constitute our genome. We show here how codon populations forming the single-stranded DNA sequences can constitute a critical approach to the understanding of junk DNA function. Then, we suggest revisiting certain methods published in our 2009 book “Codex Biogenesis”. In fact, we demonstrate here how the universal genetic code table is a powerful analytical filter to characterize single-stranded DNA sequences constituting chromosomes and genomes. We can then show that any genomic DNA sequence is featured by three numbers, which characterize it and its 64 codon populations with correlations greater than 99%. The number “1” is common to all sequences, expressing the second law of Chargaff. The other 2 numbers are related to each specific DNA sequence case characterizing life species. For example, the entire human genome is characterized by three remarkable numbers 1, 2, and Phi = 1.618 the golden ratio. Associated with each of these three numbers, we can match three axes of symmetry, then “imagine” a kind of hyperspace formed by these codon populations. Then we revisit the value (3-Phi)/2 which is probably universal and common to both the scale of quarks and atomic levels, balancing and tuning the whole human genome codon population. Finally, we demonstrate a new kind of duality between “form and substance” overlapping the whole human genome: we will show that—simult

摘要：华蟾素是一种从蟾蜍中提取的化合物,是一种传统的中草药,已被证实在癌症治疗中具有疗效。华蟾素注射液广泛应用于中国中晚期肝癌患者。本研究的目的是明确华蟾素注射液对这类特定患者的影响。在PubMed,EMBASE,CENTRAL和其他四个主要的中国数据库中检索使用华蟾素注射液治疗中晚期肝癌随机对照试验。根据Cochrane协作和RevMan 5.3的建议进行系统评价和Meta-分析。根据Cochrane手册计算风险比(RR)和相应的95%置信区间,使用随机效应模型来统计数据。最后共纳入了11项随机对照试验,728名患者。所有试验均显示,使用华蟾素注射干预组的总反应率,Karnofsky表现评分(KPS)的总反应率,1–2年生存率和生活质量均有明显改善。但是6个月生存率和临床受益率各组之间没有统计学差异。本研究发现华蟾素注射液对中晚期肝癌患者的总反应率和1至2年生存率的有益作用。因此我们认为华蟾素注射液治疗中晚期肝癌的疗效可能优于对照组。鉴于大多数试验质量较低,因此需要严格按照CONSORT for TCM设计的更高质量的前瞻性随机试验来进一步验证。
