BACKGROUND: As a reliable marker of inflammation, intercellular adhesion molecule-1 (ICAM-1) plays an important role in atherogenesis. Recently, it is assumed in researches of recent years that chronic inflammation mediated by ICAM-1 is involved in hypertensive left ventricular hypertrophy probably, but there are still some objections reported. Tanshinone ⅡA is a kind of liposoluble extract from danshen(Radix Salviae Mitiorrhizae) . It is verified in animal experiment that it can inhibit hypertensive left ventricular hypertrophy.OBJECTIVE: To investigate the relationship between ICAM-1 and hypertensive left ventricular hypertrophy and the effect of tanshinone ⅡA on expression of ICAM-1.DESIGN:A randomized controlled observation was designed.SETTING: Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology.MATERIALS: The experiment was performed in the Laboratory of Emergency Department of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from October 2002 to January 2004. Ten male WKY rats(10 WKY rats) of 12-week-old and 20 rats with spontaneous hypertension(20 SHR rats) were employed and divided into the control group(10 WKY rats), hypertension group(10 SHR rats) and tanshinone ⅡA group(10 SHR rats).injected from caudal vein for treatment and distilled water at the same dose was injected in the other two groups. Twelve weeks later, the rats were sacrificed and myocardium was collected for specimen preparation. Haematoxylin and eosin(HE) staining, VG staining, immunocytochemical staining and myocardial ED1 labeling were applied to determine myocardial macrophage infiltration degree. The reverse transcription-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay(ELISA) were used to determine the expressions of ICAM-1 mRNA and protein.MAIN OUTCOME MEASURES: Degree of macrophages infiltration and the expressions of ICAM-1 mRNA and protein in myocardium in each group.RESULTS: Twelve SHR and 10 WKY rats were employed in the experiment pared with the control group, ICAM-1 mRNA and protein expressions in hypertrophic myocardium were increased significantly in hypertension group (0.176±0.087,0.537±0.195;0.104±0.011,0.173±0.027, P <0.01or P < 0.05) . Infiltration of macrophage was significant(0. 62 ±0.07,non Ⅱ A group, the expressions of ICAM-1 mRNA and protein were decreased significantly(0. 537 ±0. 195, 0.291 ±0. 106; 0. 173 ±0.027, 0. 125± 0. 014, P < 0.01 or P < 0. 05); the amount of macrophages infiltration was decreased(1.85 ±0. 23, 1.16 ±0. 17, P < 0.05) and the degree of cardiomyocytic hypertrophy and interstitial fibrosis was remarkably relieved.CONCLUSION: Excessive expression of myocardial ICAM-1 and its mediated inflammatory cellular infiltration plays an important role in hypertensive left ventricular hypertrophy. The inhibition of tanshinone ⅡA on left ventricular hypertrophy may be contributed to decreased expression of ICAM-1 and alleviated inflammatory cellular infiltration in myocardium.

BACKGROUND: Recent studies have demonstrated that energy metabolism-related genes play important roles in intervertebral disc (IVD) cell adaptation to negative environmental factors, such as hypoxia and insufficiency of nutrient. But the effects of these genes in pressure-induced intervertebral disc degeneration remain uncertain.OBJECTTVE: To investigate continuous pressure-induced expression of energy metabolism genes: hypoxia-inducible factor 1α(HIF-lo), glucose transporter-1 (GLUT-1) and vascular endothelial growth factor (VEGF) in rabbit annulus fibrosus (AF).DESIGN: A randomized controlled experiment.SETTING: The Central Laboratory and the Laboratory of Department of Orthopaedics, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was carried out in the Central Laboratory and the Laboratory of Department of Orthopaedics, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from May to October 2005. Twenty-five Japanese white rabbits(about 4 months old, weighting 2.5-3.0 kg, provided by the Experimental Animal Center of Tongji Medical College, Huazhong University of Science and Technology) were selected to establish the animal model.METHODS: A controllable pressure-induced rabbit intervertebral disc degeneration model was adopted to impose various pressured on rabbit IVDs in vivo. The survived animals whose IVDs were compressed successfully were divided randomly into 4 groups. The IVDs were treated with no pressure as control (control group), with 15 kg axial load for 24 hours (24hours group), 72 hours (72 hours group), and 24 hours with 48 hours free for self-reparation (reparation group). Reverse transcriptase-polymerase chain reaction was used to detect the expression of HIF-1α and GLUT-1. Western Blot and immunohistochemical test were carried out for the content and distribution of VEGF.MAIN OUTCOME MEASURES: Expression of HIF-1α and GLUT-1, content and distribution of VEGF.RESULTS: Twenty of 25 rabbits entered result analysis. Two rabbits were missed because of vertebral fracture, while death of 3 rabbits within 1-3 days postoperatively caused another loss. ①HIF-1α. A very low expression was detected in the control group, while the expression in the 24 hours group was raised over 20 times than that in the control group (t=25.022, P<0.01). The expression in the 72 hours group and reparation group decreased as compared with the 24hours group. ②GLUT-1 expressed weakly in the control group. The expression in the 24 hours group rose a lot as compared with the control group (t=18.314, P<0.01) and the expression in the 72 hours group rose slightly than that in the 24 hours group (t =2.819, P<0.05). The expression in the reparation group is close to that in the 24 hours group. ③Littie VEGF content was detected in the control group, while the content rose significantly in the other 3 groups. Immunohistochemical staining showed more VEGF positive stained cells in outer AF than in inner AF.CONCLUSION: Continuous pressure can strongly up-regulate the expression of energy metabolism gene: HIF-1α,GLUT-1 and VEGF in vivo. These genes play important roles in AF adaptation and reparation in over load-caused damage.

By reviewing the research on patient reported outcomes (PRO) and the understanding of the theory of traditional Chinese medicine in coronary heart disease, the author found that the evaluation scale of PRO in coronary heart disease in traditional Chinese medicine should be guided by the theory of traditional Chinese medicine, including the theories of ‘heart-oriented, five internal organs correlation, internal injuries by seven emotions, unity of body and mind, correspondence between human and nature’ and other modern theoretical framework of PRO scale.It was believed that the physical, psychological, independence and social sphere constructed a special PRO efficacy scale of traditional Chinese medicine in coronary heart disease. The field of physiology on the scale was guided by ‘heart-based, five internal organs correlation' theory as the main line, and the scale was divided into various aspects in order to reflect all aspects of uncomfortable self-feeling of patients. Finally, 19 sides such as chest pain, chest tightness, heart palpitations, flank pain, insomnia, soreness and weakness of waist and knees, frequent urination at night, anorexia, weakness, spontaneous perspiration, shortness of breath, individual ability, daily life, positive feelings, negative feelings, personal relations and social support needed, level of social services, social intercourse and economy, healthy and medical care formed the theoretical structure model of the scale,which established the theory foundatio for the further development of PRO scale.

Objective To observe the therapeutic effect of rhubarb combined with Probiotics for treatment of patients with severe acute pancreatitis (SAP) accompanied by acute lung injury (ALI). Methods A prospective randomized controlled trial was conducted. Sixty patients with SAP and ALI were randomly divided into a rhubarb group and a combination of rhubarb and Probiotics group (combined group), 30 cases in each group. Both groups were treated with conventional therapy. On that therapeutic base, the patients in rhubarb group were treated with rhubarb 3 g·kg-1·d-1 (Raw rhubarb in boiling water 200 mL was cooked for 30 minutes, then the decoction was divided into two parts to be infused through nasal jejunal tube, retaining for 1 hour);while in the combined group, beside the above rhubarb therapy, the patients were additionally given Probiotics [Clostridium butyric acid:Chang Lekang capsule, once 1 grain (0.42 g), twice a day] through nasal jejunal tube. The therapeutic course was 14 days in the two groups. The plasma endotoxin levels, oxygenation index, and acute physiology and chronic health evaluationⅡ(APACHEⅡ) score were observed before and after treatment for 7 days and 14 days, respectively. After treatment for 30 days, the time of intestine functional recovery and mechanical ventilation, number of damaged organs, number of infectious sites, number of pancreatic pseudocysts, length of intensive care unit (ICU) stay and 30-day fatality rate were observed in the two groups. Results With the prolongation of treatment, the plasma level of endotoxin and APACHEⅡscore in the two groups were gradually reduced, and the oxygenation index was gradually increased after treatment for 7 days and 14 days in the two groups compared with those before treatment, and there were statistically significant differences in above indexes on the 14th day after treatment between combined group and rhubarb group [endotoxin (μg/L): 19.16±1.90 vs. 21.20±1.05, oxygenation index (mmHg, 1 mmHg = 0.133 kPa): 369.50±5.45 vs. 341.50±7.36, APACHE Ⅱscore:11.84±0.60 vs. 13.00±0.86, P<0.05 or P<0.01]. The length of intestine functional recovery in the combined group was longer than that in the rhubarb group (days: 5.63±1.75 vs. 5.02±1.54), the number of damaged organs (2.08±0.74 vs. 2.70±1.11), the number of infectious sites (1.93±0.64 vs. 2.23±0.83), the number of pancreatic pseudocysts (1.22±0.34 vs. 1.63±0.11) and the mortality rate [10.0%(3/30) vs. 13.3%(4/30)] in the combined group were lower than those of the rhubarb group, but there were no statistically significant differences between two groups (all P > 0.05). The times of mechanical ventilation (days: 13.40±1.76 vs. 15.60±1.28) and the length of ICU stay (days:16.13±1.25 vs. 17.63±1.30) were significantly shorter in combined group than those in rhubarb group (both P<0.05). Conclusion Rhubarb combined with Probiotics for treatment of patients with SAP and ALI can promote their recovery of lung function and shorten their length of ICU stay.
