BACKGROUND: Rhodiola rosco L acts on anti-aging,anti-fatigue and improving immunity in human body and improves angina pectoris.OBJECTIVE: To study the effect of rhodiola root on heart hemodynamics and myocardial contractility and probe into its mechanism.DESIGN: Observational and controlled based on the experimental animals.SETTING: Department of physiology in a medical university.MATERIALS: The experiment was performed in Laboratory of Cardiac Vessels of Department of Physiology of Guangxi Medical University,from January to April 2001.Thirty New Zealand white rabbits of either sex,weighted varied from 1.9 to 2.3 kg,were randomized into two groups,named as the control(physiological saline 4 mL/kg) and rhodiola sacra SH Fu (nuodikang) group(0.5 g/4 mL · kg-1),15 rabbits in each group. A hundred common wild frogs were employed,weighted varied from 120 to 160 g,randomized into 4 groups, named as the control group of physiological saline,nuodikang of small dosage group(blood concentration 209 mg/L),nuodikang of moderate dosage group(blood concentration 418 mg/L) and nuodikang of large dosage group(blood concentration 627 mg/L),25 frogs in each group.METHODS: ms2000 multiple medium biological signal analysis system was applied,by Straub method,frog heart perfusion specimen in vitro was prepared and the cardiac activity was assayed. The relevant indexes of ventricle activity in rabbits were determined with hemodynamics.MAIN OUTCOME MEASURES: Comparison of hemodynamics changes in rabbits of two groups and the comparison of effects of nuodikang at various dosages on frog heart work in vitro.RESULTS: Myocardial contractility in every nuodikang group was strengthened remarkably compared with the control(F = 8.939, P<0.01 ), the myocardial contractility in nuodikang groups at the dosages of 209 mg/L,418 mg/L and 627 mg/L was in the tendency of increasing,strengthened by 52. 3%,70. 1% and 86.4% respectively. But the significant difference was not apparent in the comparison among experimental groups(P>0.05). The significant difference in frog heart rates among groups was not apparent(P>0.05). Concerning to hemodynamics in rabbits,in nuodikang groups,the maximum increasing rate of pressure in the left ventricle was increased by 22.1% (F = 6.259,P<0.05),the mean pressure of artery was decreased by 8.2% (F = 5.688, P<0.05) . The significant difference in other indexes was not apparent in the comparison between the control and nuodikang groups.CONCLUSION: Nuodikang strengthens myocardial contractility and speeds up myocardial contraction, but does not present remarkable influence on myocardial dilation; simultaneously it reduces the mean pressure of artery.

Objective To understand the spectrum of bile pathogen in patients with cholelithiasis and their drug sensitivity to antibiotics.Methods Microbes automatic detection system was applied to detect the spectrum of bile pathogen and their drug sensitivities in 366 cholelithiasis patients who underwent choledochotomy. ResultAmong 366 specimen ,common cultures were positive in 258 (70 5%) in which 268 strains of aerobes were detected, and most of them were E.coli(121 strains,45 2%), Klebsiella pneumoniae (24 2%) and Enterococcus(10 1%). 14 strains of anaerobes were cultured in 32 specimen with an incidence of 44%,among which the most common type was B.fragilis (57%).Most pathogens in all the bile specimen were gram negative,73% in aerobes and 86% in anaerobes. Aerobes were highly sensitive to imipenem, tazobactam/piperacillin (TZP) and amikacin, with sensitive rate of 94%,83%, and 63%, respectively. The sensitive rate of anerobes to imipenem as well as TZP was 93% and 86% repectively. Conclusions The main pathogen in patients with cholelithiasis were Escherichia coli,Klebsiella pneumoniae, intestinal cocci and B.frailis which were most sensitive to those antibiotics such as imipenem and TZP.

Methods 83 patients of lumbar disc herniation were divided into observation group (n=42) and control group (n=41). Both groups received massage therapy, while the observation group was treated with spinal decompression system in addition. The effect was evaluated with Visual Analogue Scale (VAS) and Japanese Orthopedic Association (JOA) assessment of low back pain. Results The VAS score decreased and the JOA score increased in both groups after treatment (P<0.05), and it was better in the observation group than in the control group (P<0.01). Conclusion Spinal decompression system could improve the therapeutic effect on lumbar disc herniation.

Objective To evaluate impacts of acute hypervolemic hemodilution (AHH) and intra-operative cell salvage (ICS) with 6％ volume fraction of hydroxyethyl starch (HES) on hemodynamics,blood saving efficiency and renal function of orthopedic surgery patients.Methods A total of 58 patients from orthopedic surgery were involved and randomly divided into AHH + ICS group (30 cases) and control group (28 cases).Changes of hemodynamic indices (HR,MAP and CVP) and renal function indices (BUN,BCr,UCr and ALB) in both groups were compared before operation (T0),immediately after operation (T1) and at postoperative 4 hours (T2),1 day (T3) and 2 days (T4).CCr was counted and intraoperative blood conservation was observed at each time point as well.Results HR,MAP and CVP of the two groups had no significant differences.Both groups showed some drop of HR (P ＜ 0.05),but an increase of MAP and CVP at T1-T4 (P ＜ 0.05),in contrast with levels at TO.BUN,BCr and ALB also showed insignificant differences between groups or within group at each time point.CCr in the control group showed no significant difference at each time point.On the contrary,CCr in the AHH + ICS group had a fall at T1-T4 and was declined to the lowest level at T2.CCr in the AHH + ICS group showed a recovery at T3-T4 and its level at T4 was still lower than that at TO,with no significant difference.CCr in the two groups showed insignificant difference at TO,but its level in the AHH + ICS group was lower than that in the control group at T1-T4,at T2 in particular (P ＜0.01).Moreover,CCr in the two groups was still significantly different at T4 (P ＜ 0.05).Renal function indices of the two groups were all within normal range at each time point.Intraoperative blood loss and unrine volume of the two groups had no significant differences,but intraoperative fluid requirement,allogenic blood transfusion volume and transfusion rate of AHH + ICS group were notably lower than those of control group (P ＜ 0.05 or P ＜0.01).Conclusions AHH plus ICS using HES are safe,effective and promising integrated blood conservation measures,which significantly reduces intraoperative allogenic blood transfusion volume and transfusion rate and has few impacts on fundamental vital signs and renal function.However,prolonged use of large dose of HES may do harm to renal function and therefore should be carefully considered in treatment of patients with severe renal dysfunction.

Objective:To investigate the effect of compound 48/80(C48/80) activated mast cell on dendritic cell homing to draining lymph nodes(DLN) in order to explore the potential mechanism of C48/80 promoting adaptive immune response.Methods: C57BL/6 mice bone marrow derived dendritic cells(BM-DC) and MC/9 mast cell line were propagated in vitro.Chemotaxis of BM-DC supplemented with supernatant of C48/80 treated MC/9 to CCL21 was measured by transwell chemotaxis assay.C48/80 was injected into murine scapular site,local skin mast cell degranulation was detected by toluidine blue staining method.The number of CD11c+ DC in draining lymph nodes(DLN) was detected by Flow cytometry.Exogenous green microbeads labeled BM-DC homing to DLN was detected by fluromicroscope.The mice pretreated with or without C48/80 were vaccinated by ovalbumin pulsed DC(OVA-DC),DLN lymphocyte proliferation was detected by WST-8 reagent.Results: A large amount of typical BM-DC were harvested from media supplemented with murine recombinant IL-4 and GM-CSF.Product of activated MC/9 enhanced chemotaxis of BM-DC to CCL21(P<0.01).Intradermal injection of C48/80 induced local mast cell obvious degranulation and local inflammation.Mice pretreated with C48/80 demonstrated high number of total cells and DC cells in DLN.The number of fluorescent positive BM-DC in DLN also increased in C48/80 pretreated mice.Antigen specific lymphocyte proliferation enhanced in OVA-DC inoculated C48/80 pretreated mice.Conclusion: Mast cell activation induced by C48/80 can enhance DC homing to DLN and increase specific lymphocyte proliferation,which may be one of a mechanism of C48/80 in promoting adaptive immune response.
