AIM:To probe into the toxicological mechanism of sulfur dioxide (SO2) and its derivatives on cardiovascular system.METHODS: Effects of tea polyphenols (TP) on the increase in sodium current (INa) induced by SO2 derivatives in the cardiomyocytes were studied using the whole cell patch-clamp technique.RESULTS: ① The increase in INa induced by SO2 derivatives was inhibited by treating the cells with TP at different concentrations (10, 20 or 50 mg/L) in a dose dependent manner. At concentration of 50 mg/L, TP completely inhibited the increase in INa by SO2 derivatives. ② SO2 derivatives led to shift left of the activation curve. After application of TP at dose of 50 mg/L, the curve showed resumed significantly. ③ TP changed the inactivation process significantly. Before and after the application of SO2 derivatives, the half-inactivation voltage of INa was -(71.94?0.23) mV and -(65.79?0.69) mV (n=8, P0.05).CONCLUSION: TP inhibits the incremental effects of SO2 derivatives on INa, suggesting that the toxicity of SO2 on cardiomyocytes of rat is induced by free radical.

BACKGROUND:Compared with traditional autogenous bone graft, composite, as the carrier of seed cells, possesses advantages of fewer traumas and no limitation of donor site in repairing bone defect.OBJECTIVE: To observe the ability of the composite of β-tricalcium phosphate artificial bone-hyaluronic acid-type I collagen (β-TCP/HA/COL-I), as induced bone marrow stromal cell (MSC) carrier, to repair rabbit radial defect, and the feasibility with the composite as bone substitute material.DESIGN: A randomized and controlled trial.SETTING: Department of Orthopaedics, Renmin HospitaL, Wuhan University.MATERIALS; The study was conducted in the Department of Orthopaedics Renmin Hospital, Wuhan University between September 2003 and July 2004. Thirty-one New Zealand big white rabbits, aged 6 months, with body mass of 1.5 to 2.0 kg were enrolled in this study. The rabbits were randomized into control group (n =4) and experimental group (n =27).METHODS : ①In vitro induction and culture of MSCs was performed on 31 white rabbits, and the alkaline phosphatase (ALP) positive ratio of induced MSCs was observed. The structure of β-TCP/HA/COL-I was observed under scanning electron microscope. ② A 2 cm radial defect was created through operation. Eight weeks later, composites of β-TCP/HA/COL-I/MSCs were implanted into one side of rabbits in the experimental group, and autogenous bone was implanted into the other side. Rabbits in the control group were untouched. ③All the animals in the experimental group were randomly sacrificed at postoperative 4,8 and 12 weeks, 6 rabbits at 4 and 8 weeks, 15 at 12 weeks; Animals in the control group were sacrificed at 12 weeks. Gross observation, X-ray photographing, haematoxylin-eosin (HE) dyeing, and assessment of inorganic ingredient were performed. Osteogenic area and biomechanical tests were performed at 12weeks. Repairing effects on bone defect in each group were compared.MAIN OUTCOME MEASURES: The ALP positive ratio of induced MSCs; The structure of composite ofβ-TCP/HA/COL-I;Gross observation; X-ray photographing; HE dyeing and assessment of inorganic ingredient; Osteogenic area and biomechanical tests.RESULTS: All the 31 rabbits entered the stage of result analysis. ① The ALP positive ratio of cells reached 75% after induction and culture. ② Scanning electron microscope observation showed that 3 kinds of materials with abundant cellular structure distributed evenly. ③ The osteogenic area at 12 weeks was (72.5±3.6)% and (76.7±6.2)% in the experimental group and autogenous group, respectively (P ＞ 0.05). ④The maximum bending moment was (521.0±61.1) and (554.3±53.3)N·mm in the experimental group and control group, respectively; The maximum displacement at point of application of force was (0.816±0.071)and (0.870±0.103)respectively, without significant difference (P ＞ 0.05). ⑤Inorganic ingredient in the composite was 75%, 57% and 42% at 4,8 and 12 weeks respectively, suggesting that the inorganic component in the material was gradually decomposed with the elongation of time. ⑥Results of gross observation,X-ray photographing, histopathological examination, biomechanical test showed that with the elongation of time, composite of β-TCP/HA/COL-I/MSCs could repair bone defect in the experimental group, while bone defect in the control group had not been repaired.CONCLUSTON: Composite of β-TCP/HA/COL-I /MSCs possesses the same effect on repairing bone defect as autogenous bone, so it may be used as autogenous bone graft substitute.

Objectives To evaluate the association between serum cystatin C and carotid atherosclerosis.Methods Medical data,including physical examinations,serum levels of cystatin C,bilirubin,uric acid and other biochemical markers and duplex ultrasonographic scanning for the carotid artery,of 1741 healthy adults (1193 men and 548 women) who sought physical check-up at Peking Union Medical College Hospital during January 2010 and December 2011 were collected,and those with hypertension,diabetes and liver or renal function failure were excluded.Based on the results of carotid duplex uhrasonography,all the adults checked were assigned to two groups,one with thickened intima-media and atherosclerotic plaque (group A),the other with non-thickened intima-media and non-atherosclerotic plaque (group B).Difference in serum cystatin C,bilirubin,uric acid and other biochemical markers between the two groups was analyzed by using Student's t test.The correlation between the markers and carotid plaque was analyzed by using Spearman correlation analysis.The correlated factors of the carotid thickness and plaque appearance were analyzed by using unconditional Logistic regression analysis.Results Serum level of cystatin C was significantly increased in group A (t =-8.85,P ＜ 0.05).Thickness of carotid intima was positively correlated with serum cystatin C (r =0.21,P ＜ 0.05).In multivariate Logistic regression analysis,high level of serum cystatin C was not an independent risk factor of carotid atherosclerosis.Conclusion Relationship between serum cyatatin C and carotid atherosclerosis was not confirmed in our populations,which should be explored further in cohort studies.
