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.

Objective To assess the value of ultrasonic probe (USP) in the diagnosis of Submucous eminence of colorectume.Methods Sixty-eight patients with colorectal submucous eminence in 70 areas received USP under colonoscope.The accuracy of diagnosis was evaluated.Results Twenty carcinoid tumor were detected which manifested submucous hypoechoic ; Lipoma 12,located in right half colon which manifested submucous layer,clear boundaries hyperechoic; Cyst 12 manifested single or multi lattices no-echo on submucous which have integrated involucrum.Mesenchymoma or myoma levicellulare 12,most of them located inthe rectum manifested uniform or no-uniform hypoechoic on the muscularis mucosa or below and were difficult to discriminate.Malignant lymphoma,3 manifested muscularis mucosa and submucosa thickening,muscularis propria were seldom affected.Vascular diseases (hemangioma,varicosity) 3,manifested no-echoic on mucosa or submucosa,some medium,high echoic,circular or irregular,and also endometriosis 2,pigment deposition 1,appendix abscess 1,extramural compression 2,ultrasonic test is marched with clinic diagnosis.Accuracy rate is 100％.Conclusion USP can diagnose colorectal submucous eminence with high accuracy,and even provide information about the size,layer of origin,border of the colorectal submucous eminence and can distinguish benign or malignant tumor according to ultrasonic check,at the same time provide differentiation with extramural compressive lesions.

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 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.

This study was designed to determine the effects of the recombinant adeno-associated virus vector containing sense CD151 gene (rAAV-CD151) and antisense CD151 gene (rAAV-antiCD151) on the migration of Tca8113 cell. Functional fragment of CD151 gene was amplified by RT-PCR, and inserted into the vector pAAV in the sense direction and antisense direction, respectively. The rAAV-CD151 and rAAV-antiCD151 were produced and the titers were determined by dot blot. The CD151, at protein level, was detected by Western blot. The Transwell chamber was used to detect the effects of the rAAV-CD151 and rAAV-antiCD151 on the tumor cell migration. The titers of the rAAV-CD151 and rAAV-antiCD151 were 2 x 10(11) pfu/ml and 1.0 x 10(11) pfu/ml, respectively. The expression of CD151 was increased by 108% in the cells transfected with rAAV-CD151 and decreased by 79% in the cells transfected with rAAV-antiCD151, as compared with non-transfected cells, respectively. The number of the migrating cells was significantly increased in the cells transfected with rAAV-CD151 (93.56 +/- 11.59) and decreased in the cells transfected with rAAV-antiCD151 (24.00 +/- 4.36) as compared with non-transfected and rAAV-GFP transfected cells (53.00 +/- 6.56 and 46.00 +/- 7.00, P<0.05). It is an important molecular mechanism of the tumor metastasis that the overexpression of CD151 promotes the migration of the tumor cells. The rAAV-antiCD151 is a novel tool, which can reduce the expression of CD151 and inhibit the migration of the tumor cells, and brings us a new approach of anti-sene gene therapy targeted at CD151 in human carcinoma.
