Effects of Cr 6+ concentration and culture time on four heavy metal removing strains,stability of these four strains removing Cr 6+,configuration changes inside or outside their cells,effects of Cr 6+ on soluble reductive sugar inside their cells,and effect of several factors on these strains had been studied,and the Cr 6+ resistance mechanisms of these strains have been discussed elementarily. The results showed that the Lethality of these strains caused by Cr 6+ was similar with one another, namely, increasing at first, then decreasing, and finally increasing again as culture time passed. Acclimatization of Candida sp. was better than Sporobolomycetaceae sp.,and the Cr 6+ resistance of Sporobolomycetaceae sp. 7-3 was the best of the four. The research also demonstrated that the metabolic activity of these strains had been influenced by Cr 6+ in a certain extent. Scanning electron microscopy,transmission electron microscopy,and atomic force microscopy observations approved that removal of Cr 6+ by Candida sp. was depended on both surface adsorption and intracellular accumulation. Effects of Cr 6+ concentration, pH, culture time, nitrogen source, carbon source and adsorption time on these strains are not the same.

OBJECTIVE: To probe into the role of liposomal prostaglandin E(1) (Lipo-PGE(1)) on reperfusion injury in a rabbit ischemia-reperfusion model. METHODS: Twenty-four open-chest rebbits were randomized to receive a 10 min intravenous infusion of either liposome diluent, free PGE(1), or Lipo-PGE(1) after 60 min of left anterior desending (LAD) ligation just before reperfusion. Serum creatine phosphokinase (CPK), malodialdehyde (MDA), superoxide dismutase (SOD) were detected; infarct size and region at risk were measured. RESULTS: Infarct size as a ratio of weight of infarcted tissue to weight at risk (MI/RISK) was significantly reduced with Lipo-PGE(1) (32.20+/-4.70)% compared with PGE(1) (42.09+/-6.93)% or placebo (44.57+/-5.46)% infusion (P<0.01). The values of serum CPK, MDA during reperfusion in treatment of Lipo-PGE(1) group were significantly reduced than in treatment of PGE(1) group or control group (P<0.05), and the values of serum SOD were significantly increased (P<0.05). CONCLUSION: Lipo-PGE(1) can effectively decrease the serum CPK and MDA contents, elevate the SOD activity, and attenuate myocardial reperfusion injury.

AlM: To investigate the association between the degree of anterioruveitis and related factors including inflammatory markers as well as sacroiliac joint imaging in patients with ankylosing spondylitis ( AS) .
METHODS: Anterior changes evaluated by slit lamp, erythrocyte sedimentation rate ( ESR ) , C - reactive protein ( CRP ) and magnetic resonance imaging of 55 cases with AS associateduveitis were retrospectively analyzed. A modified endotoxin-induced uveitis ( ElU ) clinical standard was used for uveitis grading. SPARCC sacroiliac scoring was used to evaluate bone edema of sacroiliac joint. The correlation between the degree of uveitis and sacroiliitis was assessed.
RESULTS: ln the 55 patients with AS, ElU grading scored 2-10, and SPARCC index scored 0-22. Further analysis showed that the severity of uveitis was significantly correlated with ESR (r=0. 869, P<0. 001) and CRP (r=0. 485, P<0. 001). The degree of anterior uveitis in AS patients was not correlated with inflammation of sacroiliac joint (r=0. 237, P=0. 081).
CONCLUSlON: Local autoimmunity of uveitis and sacroiliac joint inflammation with subsequent bone formation in AS might be mutually independent processes.

This study was performed to investigate the chemical constituents in the twigs and leaves of Harrisonia perforate. Six compounds were isolated from the 95% EtOH extract of the twigs and leaves of Harrisonia perforate by silica gel, ODS, Sephadex LH-20 column chromatographies and preparative HPLC. On the basis of chemical properties and spectra data, these compounds were identified as harriperfin E (1), kihadanin A (2), kihadanin B (3), 6α-acetoxyobacunol acetate (4), gardaubryone C (5), and β-sitosterol methyl ether (6), respectively. Compound 1 is a new chromone, and compounds 2-6 are isolated from this plant for the first time.

Objective To evaluate the effects of statin on cardiac dias-tolic function and the level of B -type natriuretic peptide ( BNP) to exer-cise.Methods A total of 60 patients with diastolic dysfunction and a hypertensive response to exercise were divided into atorvastatin treatment group( n =30, atorvastatin 20 mg, once every night ) and the placebo group(n=30).The course of treatment was one year , all patients con-tinued their original therapy.Echocardiography , cardiopulmonary exer-cise testing , and the plasma BNP concentration determination at peak exercise were performed before and after treatment.Results After ator-vastatin treatment , the mitral flow velocity E wave to A wave peak veloci-ties( E/A ratio) were improved.The exercise time extended , metabolic equivalents , maximal oxygen uptake and anaerobic threshold were increased , and the exercise BNP values reduced.All of parameters had significant difference from baseline (P<0.05), only the E/A ratio,the exercise time and the exercise BNP values had significant difference com-pared with placebo ( P<0.05 ).Conclusion Atorvastatin improves car-diac diastolic function , decreases exercise BNP level , increases exercise tolerance.

Objective To evaluate the effect of atorvastatin on exercise blood pressure and exercise tolerance of patients with diastolic dysfunc-tion and hypertensive responses to exercise .Methods Sixty patients with diastolic dysfunction and hypertensive responses to exercise were se-lected and divided randomly into atorvastatin treatment group ( n =30 , atorvastatin 20 mg qn ) and control group ( n =30 ) .All patients con-tinued their original therapy .The course of treatment was one year .The data of cardiopulmonary exercise testing , exercise blood pressure meas-urement , quality of life assessment using heart failure questionnaire were compared before and after treatment . Results After treatment , the resting systolic blood pressure , pulse pressure , and the peak exercise systolic blood pressure were significantly decreased , and exercise time , metabolic equivalent ( METs ) , maximal oxygen uptake ( VO2 max ) and anaerobic threshold ( AT ) were increased , and and quality of life were improved compared with before treatment ( P <0.05 ) .

OBJECTIVETo assay ligustilide content in the herb of Szechwan Lovage Rhizome (Chuanxiong, CX), which is the dried rhizome of Ligusticum chuanxiong in order to assess the quality.

METHODLigustilide was quantitatively analyzed by high-performance liquid chromatography in 21 CX samples. An Alltima C18 column (4.6 mmx 150 mm, 5 microm) was used as the analytical column. The mobile phase consisted of water and acetonitrile (40:60). The flow rate was maintained at 1.0 mL x min(-1) with the column temperature at ambient conditions. The detection wavelength was set at 350 nm.

RESULTThe average content of Z-ligustilide in 21 CX samples was found to be 7.40 +/- 3.54 mg x g(-1)(x +/- s, n = 21). Therefore,the content of Z-ligustilide in CX should not be less than 0.66% (calculated on the dried basis).

CONCLUSIONThe overall analytical procedure is rapid and accuracy which is considered suitable for the quantitative analysis of ligustilide in CX. The amount of ligustilide in CX samples collected from different cultivation areas was obviously different. However, a relatively higher content of ligustilide was generally found in the CX collected from its main cultivated areas.
