AIM: To compare difference and similarity of transdermal therapeutics between traditional Chinese medicine(TCM) and Western Medicine, to investigate the merit and shortage of the trans-meridional-point therapeutics in TCM, and to find out the problems urgent to be resolved so as to expand external remedy of TCM.METHODS: A part of literatures of TCM about transdermal therapeutics were reviewed, and PubMed database and relevant articles in Chinese medical journals were retrieved to analyze the relevant information RESULTS: The trans-meridional-point therapeutics of TCM had a long his tory, with rich experience and definite effect. The key of it was the amplification and integrative effect produced during the process of absorption of drugs through meridional point. The research of transdermal therapeutics combined with transdermal therapeutic system(TTS) had been in a starting stage, but it was limited in the research of a disease and a prescription, being of shortage in evidence of effective mechanism and morphology. Now one of the hot points in effective mechanism of TTS was to resolve rate-limiting process for medicine transportation through the corneal layer so as to promote entering of enough medicine into the body.CONCLUSION: It is urgent to solve the essence of the morphological basis of acupoint structure, establish experimental animal mode of transdermal therapeutics, and popularize clinical application on the basis of a great deal of medicinal experiments on animals so as to bring new ideas for transdermal remedy of Chinese drug.

Objective To measure the serum levels of angiopoietin-like protein (ANGPTL) 3, ANGPTL4 and RANKL in patients with rheumatoid arthritis (RA), and the relationship between ANGPTL3/ANGPTL4 and clinical manifestations were analyzed. Methods Blood samples were drawn from 72 patients with RA and 28 healthy subjects. Serum levels of ANGPTL3, ANGPTL4 and RANKL were tested by enzyme linked immuno-sorbent assay (ELISA). Nonparametric rank sum test was used for the comparisons between groups and Spearmanˊs correlation test was used for correlation analysis. Results ① The serum level of ANGPTL3 was significantly increased in RA group compared to healthy group [800.325(577.477, 1 750.636) pg/ml vs 487.900 (382.340, 565.499) pg/ml, P<0.05, Z=-6.082]. ② The serum level of ANGPTL4 was significantly increased in RA group compared to healthy group [1 036.199(853.347, 1 746.677) pg/ml vs 706.095(558.571, 807.302) pg/ml, Z=-5.962, P<0.05].③ The serum levels of ANGPTL3 and ANGPTL4 in RA patients were increased with the rise of disease activity (DAS 28) [ANGPTL3 in the low disease activity groupwas 457.265 (373.709, 605.296) pg/ml, that of the moderate disease activity group was 785.815(679.156, 1 308.785) pg/ml, that of the high disease activity group was 1 502.038 (817.713, 1 960.493) pg/ml, P<0.05; ANGPTL4 in the low disease activity group was 737.604 (467.040, 918.222) pg/ml, that of the moderate disease activity group was 991.227 (819.456, 1 699.972) pg/ml, and that of the high disease activity group was 1 842.310 (1 252.023, 2 669.902) pg/ml, P<0.05].④ANGPTL3 and ANGPTL4 was positively correlated with RANKL (r=0.554, 0.619, P<0.01).⑤ The serum level of ANGPTL4 was significantly increased in patients with bone destruction, compared to those without bone destruction [1 624.071(949.432, 2 622.371) pg/ml vs 927.590(737.604, 1 409.798) pg/ml, Z=-2.483, P<0.05]. Conclusion The serum levels of ANGPTL3 and ANGPTL4 are increased in RA, and are both positively correlated with disease activity, moreover, ANGPTL4 is associated with pathological bone destruction.

In the present study, A fluorescent imaging-based high-throughput screening method was developed for identifying anti-migratory compounds with 96-well Transwell plates. The correlation, precision and stability of this method were examined and the incubation time of dye Hoechst 33342 in addition to migration time was optimized. In addition, The inhibitory activity of anti-cancer drug paclitaxel on tumor cell migration was assayed and an IC50 value of 0.717 micromol x L(-1) was obtained. Using this method, 24 components from Rhizoma Alismatis were screened and one component with anti-migration activity was found. These results show that the new proposed method with good precision, stability and linear range has the potential to assay the inhibitory activity of anticancer compounds.

Objective To investigate the characteristic changes in the mRNA and protein of complement 3 in spinal dorsal horn of rats with neuropathic pain,and the role of abnormal activation of complement protein in the mechanism of pain production.Methods Eighty-four healthy male SD rats were divided randomly into seven groups(n=12 for each group):normal control group,sham-operation 1d,3d and 7d groups,and chronic constriction injury of the sciatic nerve(CCI)1d,3d and 7d groups.The left sciatic nerve was ligated loosely in CCI groups,while it was only exposed but not ligated in rats in sham-operation groups.The mechanical and thermal pain thresholds were measured on 1,3 and 7 days after operation,and the mRNA and protein of complement 3 in the dosal horn of the spinal cord were determined respectively by RT-PCR,immunoturbidimetry and immunohistochemistry.Results The mechanical and thermal pain thresholds were observed to be lowered in rats one day after the sciatic nerve ligation,and a state of hyperalgesia was found to be persistent up to 7 days after CCI.This symptom was not observed in sham operation group.The expression of mRNA and protein of complement 3 in spinal dorsal horn were increased on 1,3 and 7 days after CCI.Interestingly,a high expression of mRNA of complement 3 was also observed in rats one day after sham-operation.Both mRNA and protein of complement 3 were not obviously elevated in rats of sham operation 3d,7d groups and normal control group.Conclusion The mRNA and protein of complement 3 in spinal dorsal horn are highly up-regulated in rats with neuropathic pain,suggesting that the characteristic dynamic changes in complement may contribute to the establishment and maintenance of hyperalgesia.

Objective To explore the association between VEGF gene polymorphism and the changes in cardiac function after HiHiLo. Methods Sixty two men of Han nationality from northern China underwent HiHiLo for 30 days. Training programme was as follows:exposure in hypoxic environment (14.8% - 14.3%O_2) 10hrs per day, hypoxic training three times per week (15.4%～14.8%O_2), and training at sea level in the remaining time. The genotype was analyzed by PCR-RFLP. Results There is an association between VEGF gene polymorphism and the changes in left ventricular structure and function after 4-week HiHiLo. LVM, LVMI, SV and SI after HiHiLo increased significantly in men carrying CC genotype were better than those carrying CT genotype. Conclusion Men of Han nationality carrying CC genotype probably have a better left ventricular function in response to the HiHiLo than those carrying CT genotype. CC genotype can be used as a genetic marker for the better responsiveness of left ventricular function to the HiHiLo.
