To study the mechanism of therapeutie effect of compound "Huang Dai" tablet in acute promyelocytic leukemia, twenty one patients with acute promyelocytic leukemia were treated with compound "Huang Dai" tablet. Bone marrow cells of the patients were collected before treatment and after treatment, and membrane differentiating antigen (CD33 and CD11b), cell cycle and the apoptosis correlative protein(Fas and Apo 2.7 )were detected with flow cytometry. Results showed that the expression of CD33 was decreased and that of CD11b increased, G 2 /M phase of cell cycle was blocked, and the expressions of Fas and Apo 2.7 protein were increased significantly in all patents after treatment with compound "Huang Dai" tablet. These results suggested that the mechanism of therapeutic effect of compound "Huang Dai" tablet in acute promyelocytic leukemia was induction of both differentiation and apoptosis of leukemic cells, and cell apoptosis might be related to Fas and Apo2.7 protein.

Objective To investigate the clinical singnificance of metalloproteinase(TIMP) 1 expression in human breast cancer.Methods The expression of TIMP 1 in paraffin embedded breast carcinoma specimens from 48 patients with primary invasive breast cancer who had undergone radical mastectomy or modified radical mastectomy from January of 1990 to Dcecember of 1996 were detected by the standard streptavidin biotin peroxides method,and its correlation to clinicopathologic featurea was analyzed. Ruslts Among 48 cases,the positive expression rate of TIMP 1 was 29%, TIMP 1 expression were higher in patients with higher histological grades than in those with lower ( P

To study the chemical constituents of the stems of Clematis parviloba, six compounds were isolated from a 95% ethanol extract by using a combination of various chromatographic techniques including column chromatography over silica gel, ODS, Sephadex LH-20, and semi-preparative HPLC. Two new phenolic glycosides, 2-((E)-3-carboxybut-2-en-yl)-4-hydroxy-3-methyl-phenyl-O-beta-D-glucopyranoside (1) and 4'-hydroxy-phenol-beta-D-[6-O-(4"-hydroxy-3", 5"-dimethoxy-benzoate)] glucopyranoside (2) were isolated, together with a known phenolic glycoside, 4'-hydroxy-3'-methoxy-phenol-beta-D-[6-O-(4"-hydroxy-3", 5"-dimethoxy-benzoate)] glucopyranoside (3) as well as three known megastigmane glycosides, linarionoside A (4), linarionoside C (5), and staphylionoside K (6). Their structures were determined on the basis of spectroscopic analysis and chemical evidence. Among them, compounds 1 and 2 were named as clemaparvilosides A (1) and B (2), respectively, and compounds 3-6 were obtained from Clematis genus for the first time.

To explore the relationships between traditional Chinese medicine (TCM) constitutional types and overweight or obesity so as to provide evidence for adjusting constitutional bias and preventing and treating obesity.

Starting from the clinical practice,this paper considers the common used syndrome typing in current of zang-fu differentiation are basic syndromes. It is too general,weak in pertinency and inconvenient for the clinical application. Therefore,we provide the new assumption about the detailed typing of zang-fu differentiation,and expatiate its concept,principle,basis and significance. Through these,TCM syndrome differentiation system can be expanded in some sense. The paper also provides a new way for building an objective and standard TCM system.

Objective To investigate the effect of Terpinen-4-ol on the proliferation of lung adenocarcinoma A-549 cells and its related mechanism. Methods A-549 cells were treated with different concentrations of Terpinen-4-ol. The inhibitory effect of Terpinen-4-ol on A-549 cells was tested by MTT method. Cell grow ability was determined by CCK-8 colorimetry. The ultrastructure of A549 cells were observed by transmission electron microscopy before and after Terpinen-4-ol treatment. The changes of cell cycle, apoptosis, and the level of intracel-lular calcium were inspected by flow cytometry. Inoculated the lung adenocarcinoma A-549 cells on the nude mice to form transplantation tumor. The experimental nude mice with transplantation tumors were divided into three groups:negative control group,high dose positive con-trol group and low dose positive control group. The mice were given continuously intraperitoneal injection for 10 days, and then the transplan-tation tumors were taken and the size and weight of them were detected. Results After Terpinen-4-ol treatment for 24 h,MTT assay showed that the IC50 value of A549 cells was 0. 067% v/v. The growth curves of positive control groups were significantly smooth than the negative control group. The formation of autophagosome increased after treatment with Terpinen-4-ol. The results of flow cytometry showed that the cell cycle was arrested in S phase,Terpinen-4-ol could induce apoptosis of A549 cell, The intracellular calcium concentrations in positive control groups were significantly higher than the negative control group(P<0. 05). Low dose group and high dose group restrained the growth of the transplantation tumor obviously, and the tumor inhibitory rate were 53. 33% and 77. 76% respectively. Conclusion Terpinen-4-ol has inhibitory effect on the proliferation of A-549 cells in vitro and in vivo.

Objective To investigate the proliferative inhibition effect and mechanism of total saponins from marsdenia tenacissima on human liver cancer HepG2 cells. Methods Human liver cancer HpeG2 cells cultured conventionally were divided into the marsdenia tenacissima saponins A control group, the experimental group and the blank control group. The experimental group was treated with different mass concentrations of total saponins from marsdenia tenacissima (0.14, 0.29, 0.58, 1.15, 2.13 mg/ml), while the marsdenia tenacissima saponins A control group was treated with marsdenia tenacissima saponins A (1.0 mg/ml), and the blank control group was established stimultaneously. The methyl thiazolyl tetrazolium (MTT) method was used to detect the effect of total saponins from marsdenia tenacissima on the activity of HepG2 cells, and the cell morphology was observed by using inverted microscopy. The cell apoptosis rate was detected by using flow cytometry from Annexin V-FITC/PI staining. The expressions of bcl-2, bax and p53 were analyzed by using Western blot after the drug effect. Results The results of cell activity test showed that total saponins from marsdenia tenacissima could inhibit the proliferation of HepG2 cells at the concentration of 0.29, 0.58, 1.15, 2.13 mg/ml, which was positively correlated with the concentration. The half maximal inhibitory concentration (IC 50) of cell growth inhibition of total saponins from marsdenia tenacissima on HepG2 cells was 0.75 mg/ml. Under inverted microscopy, the adherent cells were significantly reduced, the cells fell off into clusters and the debris was increased after the effect of total saponins from marsdenia tenacissima. Moreover, flow cytometry showed that total saponins from marsdenia tenacissima could increase the late apoptosis rate of HepG2 cells (P< 0.01). Western blot showed that the expression of bcl-2 was 0.62±0.16, 0.31±0.15, 0.84±0.09 and 1.00±0.11 respectively in the experimental group (total saponins from marsdenia tenacissima 0.58 mg/ml and 2.13 mg/ml), the marsdenia tenacissima saponins A control group and the blank control group;the expression of bax protein was 0.75±0.10, 0.83±0.12, 1.00±0.14 and 0.15±0.02, respectively in the above four groups; the expression of p53 protein was 0.63±0.08, 0.78±0.11, 1.00±0.13 and 0.18±0.02 respectively in the above four groups. The protein expression of bcl-2 was decreased and the protein expressions of bax and p53 were increased in the experiment group, and there was a statistical difference between the experiment group and the blank control group (P< 0.05). Conclusions Total saponins from marsdenia tenacissima can upregulate the expression of bax by upregulating the expression of p53 gene, and inhibit the expression of bcl-2, which would cause the cascade reaction to induce the apoptosis of HepG2 cells. Its inhibitory effect can be realized through mitochondrial pathmay to induce apoptosis.
