Objective To study the effect of siRNA targeting bcl-2 gene on the drug-sensitivity of HL-60 cell to homoharringtonin(HT). Methods siRNA, selected by previous experiments and packaged with lipofectamine 2000, was transferred into HL-60 cells. Six hours later, the cells were cultured with homoharringtonin. The cell growth of HL-60 cells was detected by MTT methods at 24, 48, 72 hours respectively. The level of bcl-2 protein and ROS (reactive oxygen species, ROS) as well as membrane potential of mitochondrion was determined by flowcytometry. Results The siRNA could significantly increase the inhibitive effect of homoharringtonin on growth of HL-60 cells. The combination of siRNA with homoharringtonin resulted in the falling of bcl-2 protein level and rising of ROS level as well as descending of membrane potential of mitochondrion of HL-60 significantly (P

Objective To investigate the effects of up?regulated miR?206/miR?1 on the proliferation of breast cancer stem cells and the effect mech?anism. Methods Breast cancer stem cells(BCSCs)were isolated from breast cancer cell line MCF?7 by fluorescence?activated cell sorting. Cells in the experiment were divided into the blank control group,the negative control group,the miR?206 group and the miR?1 group. The BCSCs were transfected by negative control mimic,hsa?miR?206mimic and hsa?miR?1mimic in all groups except the blank control group. MiR?206and miR?1 expression levels as well as the transcription factor EVI?1 gene were detected by real time PCR. The expression levels of the transcription factor EVI?1 protein were detected by Western blot. MTT method was used to detect the effects of miR?206 and miR?1 on the proliferation of BCSCs. Results The BCSCs(CD44+/CD24-/low cells)isolated from MCF?7 cell lines were successfully cultured in serum?free medium for subsequent studies. After transfection of hsa?miR?206mimic and hsa?miR?1mimic for 48 hours,miR?206and miR?1relative expression levels increased. EVI?1mRNA ex?pression levels significantly decreased. The results of Western blot and MTT showed that up?regulated expression levels of miR?206 and miR?1 could significantly reduce the expression of EVI?1 protein and inhibited the proliferation of BCSCs. The differences in levels of miR?206,miR?1 and EVI?1 protein were statistically significant(P<0.05). Conclusion Up?regulated miR?206 and miR?1 expression can inhibit the proliferation ability of BCSCs,which may be related to the down?regulation of EVI?1.

Objective To observe the time-effect relationship between acupuncture treatment and the absorption of cerebral hematoma and edema in the acute stage of cerebral hemorrhage to determine the optimal time for acupuncture intervention in cerebral hemorrhage.Methods Three hundred patients with cerebral hemorrhage in the acute stage were randomly allocated to treatment groups 1, 2, 3 and 4, and control group, 60 cases each. The control group received symptomatic treatment for regulating blood pressure, reducing intracranial pressure by dehydration, maintaining electrolyte balance, nourishing nerves and preventing and treating complications. The treatment groups were given acupuncture in addition. Treatment group 1 received acupuncture at 24 hrs after the attack; treatment group 2, at 72 hrs; treatment group 3, at one week; treatment group 4, at two weeks. Pre-/post-treatment hematoma size parameter difference value and cerebral peripheral edema grade parameters were observed in every group.Results There were statistically significant pre-/post-treatment differences in hematoma size and cerebral edema grade in every group (P<0.01,P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between every treatment group and the control group (P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between treatment group 1, 2 or 3 and treatment group 4 (P<0.05), between treatment group 1 or 2 and treatment group 3 (P<0.05) and between treatment groups 1 and 2 (P<0.05).Conclusions Acupuncture has a positive therapeutic effect in patients with cerebral hemorrhage in the acute stage. The earlier acupuncture intervention in the acute stage of cerebral hemorrhage, the more remarkable the effect.

Objective To investigate the incidence of osteoporosis (OP) in patients with ankylosing spondylitis and the relationship between OP and the clinical data. Methods Serum levels of bone alkaline phosphatase (BALP) and tartrate resistant acid phosphatase 5b (TRACP5b) were detected by enzyme linked immunosorbent assay ( ELISA ) in 60 cases with ankylosing spondylitis, and it was compared with normal controls. Bone mineral density (BMD) was measured through dual-energy X-ray absorptiometry ( DXA), including lumbar ( L2 - L4), bilateral femoral neck and greater trochanter. Some clinical data was collected and analyzed at the same time. Results The incidence of OP in AS patients was 35%, and the incidence of OP in the femoral proximal end was higher than that in lumbar. Compared with normal controls[ ( 1.06 ±0. 18 )U/L ], the levels of serum TRACP5b in AS[ (1.31 ± 0. 82 )U/L] patients was significantly higher ( P <0. 05 ). The levels of serum BLAP in OP combined AS group[ ( 21.65 ± 5.41 ) U/L]were significantly lower than non-OP group[ (32. 37 ± 16. 5 ) U/L] ( P <0. 05 ). The disease duration was negatively correlated with the BMD of femoral neck ( P < 0. 01 ). Conclusions There was higher incidence of OP in AS patients, which were related with the abnormality of bone metabolism and the disease duration.Multiple factors participated in the regulation of bone metabolism of AS.

OBJECTIVETo establish the quality standard of Entadae Semen, and provide scientific basis for its quality control.
METHODTLC and HPLC were used for qualitative identification and quantitative analysis of phaseoloidin and entadamide A-O-β-D-glucopyranoside in Entadae Semen. The test of water content, ash and ethanol-soluble extractives of Entadae Semen was carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition).
RESULTThe TLC was well separated with clear spots. The linear range of phaseoloidin was between 0.014 to 2.747 g x L(-1) (r = 0.999 6, n = 9) with an average recovery rate of 101.06% (RSD 0.90%, n = 6); the linear range of entadamide A-O-β-D-glucopyranoside was between 0.002 to 0.452 g x L(-1) (r = 0.999 7, n = 9) withan average recovery rate of 101.52% (RSD 1.09%, n = 6). The content of phaseoloidin in sample is between 5.12% to 9.24%, entadamide A-O-β-D-glucopyranoside is between 0.55% to 2.17%, alcohol-soluble extracts is between 30.9% to 45.2%, water is between 6.6% to 8.6%, and total ash is between 2.4% to 2.9%.
CONCLUSIONThe established standard is acceptable for quality control of Entadae Semen.
