Objective To study the effects of matrine on accumulation of ? globin mRNA and induction of erythroid differentiation in K562 cells in vitro.Methods K562 cells were cultured for 6 days with different concentration of matrine,viable cell counts were determined by trypan-blue dye exdusion test. Erythroid differentiation was evaluated by percentage of benzidine-positive cells at different days after culture. Morphological changes were observed under microscope after Wright-Gimesa staining; ? globin mRNA was quantitative by real time quantitative reverse transcript polymerase chain reaction(RT-PCR).Results Different concentrations of matrine inhibited proliferation of K562 cells in dose-dependent manner; otherwise, K562 cells were successfully induced by erythroid differentiation with matrine. After treatment with matrine, percentage of benzidine-positive cells significantly increased from 0.7% to 15.7% and characteristic changes of erythroid differentiation in the cell morphology were observed, G? globin mRNA had a preferential increase (2.7 fold)in K562 cells. Conclusions Matrine accumulation G? globin mRNA and induced erythroid differentiation of K562 cells. The results provides an experimental evidence for the pharmacological therapy of hematological diseases associated with a failure in the expression of normal ? globin genes.

OBJECTIVETo evaluate the efficacy and safety of the combination therapy of Xipayimaizipizi Capsules and Tamsulo- sin in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe randomly assigned 60 BPH patients to a control and a combination group of equal number, the former aged 62.03 ± 10.19 years with a disease course of 3.24 ± 2.18 years and the latter aged 64.77 ± 10.33 years with a disease course of 4.09 ± 2.63 years. We treated the patients in the control group with Tamsulosin at 0.2 mg qd and those in the combination group with Tamsulosin at 0.2 mg qd plus Xipayimaizipizi at 0.5 g tid, respectively, both for 4 weeks. Then, we obtained the mean frequency of nocturnal urination, maximal urinary flow rate (Qmax), residual urine volume, International Prostate Symptom Score (IPSS) , and quality of life scores (QOL) of the patients, and recorded their adverse reactions.

RESULTSBefore treatment, the nocturnal urination frequency, Qmax, IPSS, and QOL were 3.60 ± 1.81, (10.40 ± 3.53) ml/min, 22.47 ± 8.58, and 4.43 ± 1.50 in the control group, as compared with 3.43 ± 1.61, (10.14 ± 3.43) ml/min, 21.93 ± 8.79, and 4.73 ± 1.31 in the combination group. After 4 weeks of medication, the combination group showed more significant improvement than the control in the nocturnal urination frequency (1.30 ± 1.18 vs 2.27 ± 1.60), Qmax ([13.85 ± 3.15] vs [14.36 ± 3.03] ml/min), IPSS (13.00 ± 1.53 vs 17.20 ± 8.43), and QOL (2.57 ± 1.61 vs 2.93 ± 1.68), all significantly better than the baseline (P < 0.05). The combination therapy achieved remarkable improvement as compared with the control in the nocturnal urination frequency (- [2.13 ± 1.11] vs -[1.73 ± 1.07]), IPSS (- [8.93 ?6.01] vs -[4.80 ± 3.87]), and QOL (- [2.17 ± 1.12] vs -[1.50 ± 1.01]) (P < 0.05), but exhibited no significant differences from the latter in Qmax ([3.72 ± 2.281 vs [3.95 ± 2.53] ml/min) and residual urine volume (- [34.30 ± 37.43] vs - [26.43 ± 30.49] ml) (P > 0.05). Adverse reactions were found in 5 cases in the combination group (16.67%) and 3 cases in the control (10%) , with no remarkable differences between the two groups (P > 0.05).

CONCLUSIONThe combination therapy of Xipayimaizipizi Capsules and Tamsulosin can improve the symptoms of BPH and the patients quality of life of.

Traditional Chinese medicine(TCM) is a complex system, featured with integrity and characteristics. Structural component TCM is a well-organized integrity of traditional Chinese medicine, reflecting multi-component integration effect of TCM. It gives us a new view on the material basis of TCM. Currently, conventional researching strategies are not enough to deal with the relationship between material basis and efficacy, multi-composition, multi-targets, and multi-section mechanism. Post-genome area gives a birth to bioinformatics, which involves systematic biology, different levels of omics, corresponding mathematics and computer techniques. It increasingly becomes a powerful tool to understand complicated system and life essential laws. Research ideas, methods. and knowledge of data mining technology of bioinformatics combined with the theory of structural components of Chinese medicine bring a new opportunity for developing structural components of Chinese medicine, systematically exploring the essence of TCM and promoting the modernization of TCM.

To prepare sagittatoside B with epimedin B Hydrolyzed from cellulase. With the conversion ratio as the index, the effects of pH value, temperature, reaction time, dosage of enzyme and concentration of substrates on the conversion ratio were detected. L9 (3(4)) orthogonal design was adopted to optimize the preparation process. Hydrolyzed products were identified by MS, 1H-NMR, and 13C-NMR. The results showed that the optimum reaction conditions for the enzymatic hydrolysis were that the temperature was 50 degrees C, the reaction medium was pH 5.6 acetic acid-sodium acetate buffer solution, the concentration of substrates was 20 g x L(-1), the mass ratio between enzyme and substrate was 3: 5, and the relative molecular mass of the reaction product was 646.23. NMR data proved that the product was sagittatoside B. The process is simple and reliable under mild reaction conditions, thus suitable for industrial production.

An increasing number of monopartite begomoviruses are being identified that a satellite molecule (DNAbeta) is required to induce typical symptoms in host plants. DNAbeta encodes a single gene (termed betaC1) encoded in the complementary-sense. We have produced transgenic Nicotiana benthamiana and N. tabacum plants expressing the betaC1 gene of a DNAbeta associated with Tomato yellow leaf curl China virus (TYLCCNV), under the control of the Cauliflower mosaic virus 35S promoter. Transgenic plants expressing betaC1 showed severe developmental abnormalities in both species. Microscopic analysis of sections of both transgenic and non-transgenic N. tabacum leaves showed abnormal outgrowths of transgenic N. tabacum to be due to disorganized cell division (hyperplasia) of spongy and palisade parenchyma. Immuno-gold labeling of sections with a polyclonal antibody against the betaC1 protein showed that the betaC1 protein accumulated in the nuclei of cells. The possible biological function of the betaC1 protein was discussed.
