AIM: To investigate the relationship between expression of Bmi-1(B cell-specific MLV integration site-1) in gastric cancer and its clinicopathologic significance.METHODS: 146 surgical patients with gastric carcinoma were followed up at least 2 years.Expression of Bmi-1 protein was examined by immunohistochemistry in their archival paraffin embedded tissue specimens.RESULTS: The intensive positive rate of Bmi-1 expression in gastric cancer was 67.8%(99/146).Expression of Bmi-1 was highly correlated with tumor size,clinical stage,lymph node metastasis and T classification(P0.05).The survival rate in the patients with Bmi-1 expression was much lower than that in those patients without Bmi-1 expression(P

Objective:To investigate the effects of Neibu Huangqi Decoction combined with Kangfuxin Liquid on wound healing after hemorrhoid fistula.Methods:Randomized controlled trial. A total of 90 patients with hemorrhoid fistula surgery in Tangshan Hospital of Traditional Chinese Medicine from January 2020 to June 2021 were selected as the observation objects and divided into 2 groups by random number table method, with 45 cases in each group. The control group was treated with Kangfuxin Liquid after surgery, and the observation group was treated with Neibu Huangqi Decoction. Both groups were treated continuously for 14 days. Wound symptom score was performed before and after treatment. The levels of TNF-α, IL-6 and IL-8 were determined by ELISA. The wound healing time was observed and the wound healing rate was calculated. Adverse reactions were recorded and clinical efficacy was evaluated.Results:The total effective rate was 93.33% (42/45) in the observation group and 66.67% (30/45) in the control group, with statistical significance ( χ2=9.89, P=0.002). After treatment, the scores of pain [(0.63±0.14) vs. (0.97±0.27), t=7.50], exudation [(0.67±0.12) vs. (1.09±0.31), t=8.48], edema [(0.78±0.17) vs.(1.25±0.36), t=7.92], pruritus [(0.78±0.20) vs. (1.32±0.33), t=9.39] were lower than those in the control group ( P<0.01); serum TNF-α [(33.46±2.86) μg/L vs. (45.78±3.92) μg/L, t=25.39], IL-6 [(41.86±5.84) μg/L vs. (56.12±6.75) μg/L, t=15.98], IL-8 [(27.40±3.58) ng/L vs. (36.16±3.84) ng/L, t=16.69] were lower than those in the control group ( P<0.01). The wound healing time of the observation group was shorter than that of the control group ( t=8.60, P<0.01), and the wound healing rate was higher than that of the control group ( t=24.65, P<0.01). During treatment, the incidence of adverse reactions was 11.11% (5/45) in the observation group and 6.67% (3/45) in the control group, without statistical significance ( χ2=0.14, P=0.711). Conclusion:Neibu Huangqi Decoction combined with Kangfuxin Liquid can promote wound healing, reduce inflammatory cytokines, relieve pain and exudation, improve clinical efficacy, and have few adverse reactions.

Pulsatile blood flow plays an important role in maintaining normal vascular endothelial function. Quantitative measurement of pulsatility of artery blood pressure and blood flow in dogs and effects of enhanced external counterpulsation (EECP) on the pulsatility were taken in this study. Common carotid artery blood pressure and blood flow were measured in 6 beagle dogs that had suffered from an acute myocardial infarction 6 weeks before. A 6F tip transducer catheter was inserted into the right common carotid artery to measure blood pressure, and blood flow was measured in the left common carotid artery by an electromagnetic blood flow probe under anesthesia before and during EECP. Blood pulse pressure, pulsatility index (ratio of peak pressure to end diastolic pressure) and standard deviation of blood pressure were calculated to evaluate the pulsatility of arterial blood pressure. Blood pulse flow, pulsatility index (ratio of peak flow to trough flow) and standard deviation of blood flow were calculated to evaluate the pulsatility of blood flow. Mean vascular resistance (MVR) was calculated as MVR = mean blood pressure/mean blood flow. Blood pulse pressure, pulsatility index and standard deviation of blood pressure were elevated from 30 +/- 9 mmHg, 1.26 +/- 0.05 and 8.7 +/- 2.5 mmHg to 43 +/- 8 mmHg (P < 0.05), 1.54 +/- 0.13 and 12.4 +/- 2.0 mmHg (P < 0.05) before and during EECP, respectively. Blood pulse flow, pulsatility index and standard deviation of blood flow were elevated from 317 +/- 48 ml/min, 2.85 +/- 0.21 and 96 +/- 21 ml/min to 447 +/- 88 ml/min, 4.56 +/- 0.90 and 131 +/- 39 ml/min before and during EECP (P < 0.05). MVR was decreased from 578 +/- 72 before EECP to 476 +/- 85 Wood units during EECP(P < 0.05). These data demonstrate that EECP gives an elevation of pulsatility to blood pressure and blood flow, thus it may lead to the decrease of vascular resistance.

Pulsatile blood flow plays an important role in maintaining normal vascular endothelial function. Quantitative measurement of pulsatility of human arterial blood pressure and the influence of enhanced external counterpulsation (EECP) on the pulsatility were investigated in this study. Eight healthy young male volunteers aged 22 to 35 were included. A 4F tip transducer catheter was inserted under local anaesthesia into the radial artery up to the aortic arch. Intraarterial blood pressure was recorded before and during EECP. Blood pulse pressure, pulsatility index (ratio of peak pressure to end diastolic pressure) and standard deviation of blood pressure in 5 cardiac cycle was calculated to evaluate the pulsatility of arterial blood pressure. The results showed that blood pulse pressure, pulsatility index and standard deviation of blood pressure were elevated from 47 +/- 5 mmHg, 1.64 +/- 0.11 and 13.6 +/- 1.5 mmHg to 77 +/- 3 mmHg, 2.46 +/- 0.25 and 19.3 +/- 2.2 mmHg before and during EECP respectively (P < 0.05). Decreasing of systolic pressure and increasing of diastolic pressure during counterpulsation were also observed. EECP gives an elevation of pulsatility to human blood pressure.
