Objective To study the effect of acupuncture on systolic and diastolic blood pressure and pulse rate of patients with different diseases. Methods Blood Pressure and Pulse Rate of 106 patients older than 18 without history of needling during the last month, were measured before and immediately after every treatment session. Also history of hypertension, history of needling and acupoints were recorded for every patient. Results After acupuncture, systolic blood pressure, diastolic blood pressure and pulse rate significantly decreased comparing to the levels before acupuncture (P<0.01). History of needling and hypertension did not affect the outcome of acupuncture on BP and PR (P>0.05) . There is a correlation between acupuncture in some acupoints and blood pressure or pulse rate (P<0.05 or P<0.01) . Conclusion Acupuncture in some acupoints has certain effects on blood pressure and pulse rate.

This study examined the effect of integrin cytoplasmic domain-associated protein 1α (ICAP-1α) and its mutatants T38A and I138A on the adhesion, migration and tube formation of 2H-11 cells. rAAV-ICAP-1α, rAAV-T38A and rAAV-I138A were constructed. After infection, the expression of ICAP-1α and p-ERK1/2, p-c-Jun protein was measured by Western blotting. Adhesion ability was evaluated by using MTT. Cell migration was determined by using Boyden chamber method. Tube formation test was conducted on Matrigel. The results showed that in ICAP-1α, T38A and I138A groups, ICAP-1α protein expression was increased. In T38A and I138A groups, phospho-ERK1/2, phospho-c-Jun protein expressions were significantly increased as compared with the control group and the GFP group. ICAP-1α group protein expression was obviously decreased when compared with the control group and the GFP group. Cell adhesion ratio was 0.1429±0.0080 in control group, 0.1434±0.0077 in GFP group and the ratio in T38A and I138A groups increased to 0.3210±0.0082 and 0.3250±0.0079, respectively. In ICAP-1α group, the ratio was decreased to 0.1005±0.0073. In T38A and I138A groups, the number of migrating 2H-11 cells was increased to 31.45±3.20 and 33.10±5.40 against 18.51±2.80 in control group and 20.47±3.12 in GFP group. In ICAP-1α group, the number was decreased to 12.06±1.72. The number of tube-like structures was increased to 20.41±2.54 in T38A and to 22.26±3.07 in I138A groups as compared to those of control group 12.45±1.84 and GFP group 13.63±2.71. In ICAP-1α group, the number of tube-like structures was decreased to 8.32±1.24. It was suggested that rAAV-T38A and rAAV-I138A transfection can substantially increase 2H-11 cell adhesion, migration and angiogenisis, while rAAV-ICAP-1α can greatly inhibit the effect. These effects might be correlated with ERK1/2 and c-Jun protein phosphorylation.

Objective To enrich breast cancer stem cells of breast cancer cell lines MCF-7 and MDA-MB-231 through culturing mammospheres,and to detect the expression differences of gene of breast cancer stem cells makers.Methods The MCF-7 and MDA-MB-231 cell lines were cultured by serum and serum-free medium.The proportion of CD44+/CD24-and CD133+ cancer stem cells was measured in cells derived from mammosphere cells or monolayer culture cells by flow cytometry,and the expression of CD44,CD24,CD133,ALDH3A1,ABCG2 and CXCR4 mRNA were detected by RT-PCR.Results Flow cytometry analysis indicated that the CD44+/CD24-low proportion of the MCF-7 mammosphere cells was higher than its adherent culture cells (P < 0.05),and CD133+ proportion had no difference between them (P > 0.05).However,the CD44+/CD24-/low proportion of the MDA-MB-231 mammosphere cells was lower than its adherent culture cells (P < 0.05),while CD133+ proportion was significantly higher than its adherent cultured cells (P < 0.05).RT-PCR analysis suggested that the expression of CD44 and ABCG2 increased obviously in MCF-7 microspheres (P< 0.05),and the expression of CD24,CD133,ALDH3A1 and CXCR4 had no significant difference between the mammosphere cells and adherent culture cells (P > 0.05).The CD24,CD133,ABCG2,ALDH3A1 and CXCR4 increased obviously in MDA-MB-231 microspheres.On the contrary,the CD44 decreased (P < 0.05).The expression of CD44 and CD24,CD133 and ALDH3A1 had significant differences in the microspheres of MCF-7 and MDA-MB-231 cells (P < 0.05).Conclusion The related cancer stem cells gene expression is different in the microspheres of human breast cancer cell line,which indicates that the different subtypes of breast cancer may be derived from different origins.

Objective: To determine the appropriate time of early administration of dopamine (DA) before nitroglycerin (GTN) for establishing rat model with vasomotor abnormalities. Methods: Rats were divided into 5 groups: normal group, DA Group and other 3 groups in accordance with DA at different time points (10, 30, 45 min) plus GTN .Common carotid artery (CCA) blood flow velocity was dynamically measured with pulsed Doppler flow probe to evaluate the influence of DA, GTN on blood flow velocity rate(BFVR). Results:The blood flow velocity rate induced by DA of All medication administration was different from the normal group within 10 minutes(P < 0.05). However, the differences were not statistically significant after 11 min(P > 0.05). The BFVR of 10min interval group had differences with the DA group at 45min, 50min, 55min, 60min, 65min and 70min(P < 0.05 or P < 0.01). CCA BFVR of 45 min interval group was statistically significant different from the DA group at 80, 85, 90, 95 min and 100 min(P < 0.05). No statistically significant differences existed between CCA BFVR of 30min interval group and DA group (P > 0.05). Conclusion: Subcutaneous injection of DA, 45m in after injection of GTN can induce vasomotor abnormalities in rat with phase characters. The model may be useful for vasoactive screening of anti-migraine drugs.

In this study, whole cell patch clamp recording technique was employed to investigate the effect of Shenmai Injection (SMI) on L-type calcium current of diaphragmatic muscle in rats. The result showed that when the diaphragmatic muscle cell was held at -80 mV and depolarized to +60 mV, 10 microl/ml, 50 microl/ml and 100 microl/ml SMI enhanced the inner peak L-type calcium current from -(6.8 +/- 0.7) pA/pF (n=7) to -(7.3 +/- 0.8) pA/pF (P>0.05, n=7), -(8.6 +/- 1.0) pA/pF (P<0.05, n=7) and -(9.4 +/- 1.2) pA/pF (P<0.05, n=7), respectively, The rates of L-type calcium current were increased by (7.34 +/- 2.37)%, (25.72 +/- 5.94)%, and (38.16 +/- 7.33)%, respectively. However, it had no significant effect on maximal activation potential and reversal potential. Our results suggested that SMI could activate the calcium channel of the diaphragmatic fibers of the rats, increase the influx of Ca2+, and enhance the contractility of diaphragmatic muscles.
