OBJECTIVE:To study the long-term toxicity of Reketing granules.METHODS:The experiment was performed in 4 groups:one control group(normal saline)and three Reketing subgroups(188 g?kg-1,94 g?kg-1,18 g?kg-1).After intragastrical administration for 3 consecutive months,the blood routine,urine routine and serum biochemical indicators were measured in rats,and the autopsy of the major organs was performed.After drug withdrawal for 2 weeks,the above indexes were measured again to find out the abnormality.RESULTS:After 3-month medication,the rats experienced a gradual increase in body weight and developed well.In Reketing high dose-treated group,glutamate-pyruvate transaminase(GPT)and blood urea nitrogen(BUN)levels increased slightly;and except for lesion of liver and kidney in small number of rats,the peripheral hemogram,urine routine and the blood biochemical indicators were all normal.The above indexes and the pathological findings of the organs after drug withdrawal for 2 weeks were all normal.CONCLUSION:Reketing granules can lead to mild lesion of liver and kidney of rats during medication,but the symptoms disappear after drug withdrawal.

Objective: To prepare dexketoprofen trometamol hydrogel patches, optimize the formula and evaluate in vitro transdermal properties.Methods: Dexketoprofen trometamol hydrogel patches were prepared with NP-800 as the hydrogel patch carrier, aluminum hydrochloride as the crosslinking agent, EDTA as the crosslinking modifier and glycerol as the moisturizing agent.The formula was screened by orthogonal design with the initial viscosity, holding force, peel strength and 12 h cumulative transdermal quantity as the evaluation indices to screen out the best formula.The transdermal absorption test was carried out with an improved Franz diffusion cells to compare the enhancement of Aznoe, oleic acid and menthanol on dexketoprofen trometamol hydrogel patches.Results: The best formula was as follows: the mass percentage of NP-800, glycerol, glycerol and EDTA was 5%, 0.3% , 25% and 0.15% , respectively.The transdermal enhancers had transdermal enhancement on dexketoprofen trometamol, and among them, 3% Azone had the most significant enhancement with the enhancing rate of 3.26.Conclusion: The preparation and formula of dextroxyprofen trometamol hydrogel patches are stable, reasonable and feasible.

Objective To observe the degradation pattern of tubulin in the cardiac muscle and lung tissue of rats after death.Methods 24 young male Sprague-Dawley rats were divided into 6 groups averagely.After being killed by bleeding,the rats were kept in an artificial climate incubator;the experimental temperature was kept at 20℃ and humidity at 50%.Proteins in cardiac muscle and lung tissue were extracted and tubulin was then examined by Western blot.Thereafter,the semi-quantitative analysis of the Western blot images was performed.Results Tubulin can be detected in the normal cardiac muscle and lung tissue of rats.After 1d postmortem,the tubulin content in these tissues began to decline,and it might still be detected at 7d postmortem,but the tubulin content in lung decreased faster than that in cardiac muscle.A linear relationship between tubulin content in cardiac muscle and lung of rats and the postmortem interval was determined.The linear regression equations and coefficients for integral optic density in relation to PMI were y=-1726.1x+14083 with correlative coefficient r=0.9684 for cardiac muscle and y=-1439.89x+12041 with correlative coefficient r=0.9808 for lung,respectively.Conclusion The level of tubulin in cardiac muscle and lung tissue of rats varied with PMI and the time dependent degradation of this protein was potentially useful for the PMI estimation.

Objective To establish a novel method to detect autoantibodies against platelatespecific receptors by flow cytometric bead assay and study its clinical application. Methods The beads were coated with monoclonal antibodies SZ2, SZ22, SZ21 and 7E3 against platelet GP Ⅰ b, GP Ⅱ b, GP Ⅲa and GP Ⅱ b/Ⅲ a, respectively. Captured platelet glycoprotein and beads complex was detected by FITC labeled polyclonal goat antihuman immunoglobulin using flow cytometer. The platelet samples that reacted with antibodies (SZ2, SZ22, SZ21 and 7E3) negatively and positively were tested, respectively. Each sample was repeated 20 times to generate intra-day CV for the MFI and once a day for 8 days to generate inter-day CV values. The 85 ITP patients, 17 NITP patients and 50 controls from the First Affiliated Hospital of Soochow University during March 2006 to December 2008 were included in the studies. The sensitivity and specificity of these four platelet antibodies to diagnose ITP were analyzed using ROC curve. The results were compared with MAIPA. Results The CV of the intra-day-assay for samples negative to antibody SZ2, SZ22,SZ21 and 7E3 were 3.26%, 2. 86%, 1.65% and 4. 94%, respectively; While the CV of the intra-day-assay for samples positive to antibody SZ2, SZ22, SZ21 and 7E3 were 6. 16%, 4. 88%, 5.20% and 5. 85%,respectively. The CV of the inter-day-assay for samples negative to antibody SZ2, SZ22, SZ21 and 7E3 were 5. 86%, 4. 74%, 5.69% and 7.56%, respectively; While the CV of the inter-day-assay for samples positive to antibody SZ2, SZ22, SZ21 and 7E3 were 7.53%, 5.49%, 7.11% and 6.25%,respectively. The MFI for SZ2 in ITP group, NITP group and healthy control group were 1.49(0. 88-16. 24),1.12(1.00-1.33), 1.01 (0. 83-1.37), respectively, which showed significant differences (H = 36.89,P＜0.01). The MFI for SZ22 in the three groups were 1.55 (0.84-11.30), 1.13(1.03-1.29), 0.98(0. 85-1.24), respectively (H=28.41, P ＜0.01). The MFI of SZ21 were 1.50 (0.87-11.04), 1.13(0.97-1.32), 1.05 (0.85-1.48), respectively (H=54.42, P＜0. 01). The MFI for7E3 were 1.51(0. 84-9.81), 1.05(0.86-1.13), 1.03 (0.74-1.28), respectively (H =31.97, P ＜0.01). Based on ROC analysis, with cut-off values of 1.37, 1. 24, 1.48 and 1.28 for SZ2, SZ22, SZ21 and 7E3,respectively, the AUC were 0. 86, 0.90, 0. 87 and 0. 84, respectively. The sensitivities of the assays were 58. 82% (50/85), 52. 94% (45/85), 52.94% (45/85) and 51.76% (44/85), respectively. When all four antibodies were used, the sensitivity was increased to 74. 12% (63/85), which was higher than that of MAIPA [ 50. 59% (43/85) ,χ2 = 6. 78, P ＜ 0. 05) ]. Conclusion Flow cytometric bead assay can be used to detect four platelet-specific autoantibodies simultaneously, and may be a useful method to aid in the diagnosis of ITP.

Objective To investigate the correlations between the time of thoracic endovascular aortic repair (TEVAR) and prognosis in patients with type B acute aortic dissection (AADB). Methods The clinical data of 156 AADB patients with TEVAR was retrospectively analyzed and divided into 3 groups according to the time from onset of symptom to TEVAR:less than seven days was deifned as group 1 (G1, n=87), seven days to fourteen days group 2 (G2, n=48);more than fourteen days was group 3 (G3, n=21). The status of aortic reconstruction at three months TEVAR, in-hospital mortalities, mean hospital expense and length of stay were compared among three groups. Results Before TEVAR, there was no signiifcant differences in the ratio of smallest true lumen diameter and largest false lumen diameter amony the three groups (0.47±0.33, 0.42±0.18, 0.47±0.27, respectively, P>0.05). At three months after TEVAR, the ratio of largest true lumen diameter and largest false lumen diameter among the three groups was signiifcantly greater in group 1 (1.76±0.51) than group 2(1.42±0.30) and group 3(1.34±0.34, P < 0.05), when there was no signiifcant difference between the later two groups. Complete aortic reconstruction (8 from group 1 and 4 from group 2) was achieved in 12 patients at 3 months after TAVAR. Eight patients died during hospitalization, 5 from visceral ischemic, 2 from proximal aortic dissection, one patient from sudden death. Compared with G3, the hospital expense of group 1 and group 2 was cut down about ￥20000. Length of stay was signiifcant greater in group 3 than in group 1 and group 2 (P<0.05). Conclusions Early TEVAR for AADB was safe and beneifcial for aortic reconstruct and reducing the hospital expense and length of stay.
