Objective To investigate the clinical usage of Traditional Chinese Medicine Theory "kidney produce marrow,marrow produce blood,marrow and blood originate from kidney" in aging delay.Methods Several animal models(including radiation damaged,hemolytic anemia,Myrelan induced haematopoietic impedient anemia,emasculated rooster,emasculated rat,aged rat,glucose induced senescence rat/mouse,ozone induced aged mouse,aged Golden hamster,aged partridge and the fifth instar larva of silkworm etc)were applied to study the mechanism of the aging delay,and "Bushenshengxue" medicine were also used in treating ?-thalassemia patients.Results Significantly results were observed both in aging delay study guided by Traditional Chinese Medicine Theory "kidney produce marrow,marrow produce blood,marrow and blood originate from kidney" and in ?-thalassemia clinical study.The results indicated the science connotation of this theory.Conclusion The Traditional Chinese Medicine Theory "kidney produce marrow,marrow produce blood,marrow and blood originate from kidney" is the main basic mechanism of aging delay and single gene heredity disease treating with TCM.

Objective To investigate the survival situation of thalassemia cases treated with Bushen Yisui Method. Methods The survival situation of 197 cases were investigated by telephone. Results The total survival rate of 197 cases is 87.3%, among which the thalassemia major is 65.71%, the thalassemia intermedia is 99.2%, the ?-thalassemia is 100%, the ?-thalassemia is 85.0%. 158 of 197 cases have been analyzed genotype, among which 63.16% is the survival rate of homozygote, 89.16% of the heterogenic duplex heterozygote, 100% of the heterozygote. To ?-thalassemia, the survival rate has these trends:the major

Methylation of histone by protein arginine methyltransferases (PRMTs) plays an important role in gene regulation. PRMT1- and PRMT4-catalyzed methyl-arginine is involved in transcription activation, while PRMT5- and PRMT6-catalyzed methyl-arginine is associated with transcription repression. Histone arginine methylation can be dynamically regulated in vivo, and methyl-arginine is demethylated by "arginine demethylase". Here, the most recent progresses in the methylation studies of histone arginine were summarized.

Objective To study the clinical effect of compound Yisui Shengxue Keli(YSSXKL) on treating ?-thalassemia. Methods By using self-control study method,30 cases of major and intermediate ?-thalassemia had been first treated with placebo for three months,then were treated with YSSXKL in the followed three months in Guangxi province,the high incidence area of the disease. The clinical symptoms,traditional Chinese medicine symptoms and dynamic changes of the blood levels of Hb,RBC,Ret and HbF were observed before and after each treatment. The CRF tables were filled in according to the traditional Chinese medicine symptoms of the patients and the side effects recorded. Results During period of placebo treatment,the main curtive effective indexes Hb and RBC were not obviously raised,while the RBC levels were inversely degraded after the first month of taking placebo orally(P

Objective To explore the inhibitory effects of SB203580, a specific inhibitor of p38 mitogen activated protein kinase (p38 MAPK) on hyper secretion of airway mucus in mice with asthma. Methods Forty BABL/C mice were randomly allocated into asthma group, SB203580 treatment group, dexamethasone treatment group and control group (sham-challenged group). Mice in SB203580 treatment group were intraperitoneally injected with SB203580 (10mg/kg), while those in dexamethasone treatment group were injected with dexamethasone (1mg/kg) before provocation. The number of goblet cells in small bronchi of all groups was determined after Alcian blue-periodic acid Schiff (AB-PAS) staining. The contents of MUC5AC in bronchoalveolar lavarge fluid (BALF) were evaluated with ELISA asssy. The levels of MUC5AC mRNA expression were determined with reverse transcription-polymerase chain reaction (RT-PCR) assay, and gray-scale analysis was done with image analysis method. Results Compared with the normal group, the number of airway goblet cells, the contents of MUC5AC in BALF and the level of lung MUC5AC mRNA expression in asthma group were raised significantly (P

The ingredients of compound "Baxianjiangtang" are Radix Rehmanniae, Radix Polygoni Multiflori preparate, Rodix Astragali, Radix Ophiopogonis etc. Pharmacological tests showed that it can decrease LPO and increase the activity of SOD in blood and liver of Alloxan induced diabetic rats and mice.It also increased that phagocytosis of phagocytes of experimental anim als. It can increased tolerance to fatigue at low and high temperature conditions. According tothe above results, it can be considered as safe and effective.

To evaluate the effects of Yisui Shengxue Granules on expressions of alpha-hemoglobin stabilizing protein (AHSP) and erythroid transcription factor GATA-1 mRNAs in bone marrow of patients with beta-thalassemia, and to explore its possible molecular mechanism.

Aplastic anemia (AA) is a Tlymphocyte-mediated autoimmune disease. The research on AA was focused on three areas, which were the pathogenesis of immune dysfunction, hematopoietic stem cell damage and abnormal hematopoietic microenvironment. In recent years, more attentions have been paid on abnormal immune mechanisms in the blood. There are complex intracellular cytokine and signal transduction pathway of pathogenesis in AA. And T-bet/IFN-γ signaling pathway plays an important role in development and progression of AA. This article aimed to review T-bet/IFN-γ signaling pathways in AA.

To observe the effects of Yiqi Huoxue Formula (YQHXF), a compound Chinese herbal medicine, on transforming growth factor-β (TGF-β)/smad signal transduction pathway and connective tissue growth factor (CTGF) in rats with renal interstitial fibrosis

This study was aimed to investigate the effect of Bu-Shen Y i-Sui Sheng-Xue (BSYSSX) method on pro-liferation and differentiation mechanisms of hematopoietic progenitor cells. The rat models were established by 60Co-γrays and cyclophosphamide. Compound Chinese medicine was gavaged to rats of the normal control group, model group, stanozolol group, Yi-Sui Sheng-Xue (YSSX) group, Wen-Shen Sheng-Xue(WSSX) group and Zi-Shen Sheng-Xue (ZSSX) group. Then, serum of rat was prepared. Rat bone marrow cells were incubated with AA rats serum ac-counted for 20% and the number of hematopoietic progenitor cells colony-forming units (CFU) were counted. The level of GATA-1 and PU.1 mRNA in colony cells were detected with RT-PCR. The results showed that compared with the normal control group, the number of bone marrow cells, CFU-E, BFU-E, CFU-GM, as well as the expres-sion of GATA-1 and PU.1 mRNA in the model group decreased significantly (P< 0.01). Compared with the model group, the number of bone marrow cells, CFU-E, BFU-E, CFU-GM of each treatment group were significantly in-creased (P< 0.01). CFU-E and BFU-E of the ZSSX group were better than the YSSX group (P < 0.01). CFU-GM of the ZSSX group was better than the YSSX group and the WSSX group. The expression of GATA-1 and PU.1 mR-NA in each treatment group were significantly higher than the model group (P< 0.01). The expression of GATA-1 mRNA in the ZSSX group was better than the YSSZ group and WSSX group (P< 0.05). The expression of PU.1 mR-NA in the ZSSX group was higher than the YSSX group and WSSX group. It was concluded that BSYSSX method may increase the expression of GATA-1 and PU.1 mRNA in order to promote the proliferation and differentiation of bone marrow hematopoietic progenitor cells. The ZSSX method was better than the YSSX method and WSSX method.
