Objective: To establish an HPLC method for the fingerprint analysis on Chinese materia medica (CMM) elephant skin so as to provide the evidence for the quality control and application of elephant skin. Methods: To extract amino acids by the method of hydrolysis in 6 mol/L HCL and use phenyl isothiocyanate (PITC) as the derivating agent. The Hypersil ODS-2 C18 column (250 mm × 4.6 mm, 5 μm) was used. Under the condition of gradient elution, the flow rate was 1.0 mL/min, the UV detection wavelength was 254 nm, and the column temperature was 40℃. The similarity was analyzed with "Similarity Evaluation System for Chromatographic Fingerprint of TCM 2004A". Results: The HPLC characteristic fingerprint of elephant skin has been established. A total of 18 common peaks were characterized, and 17 of them were identified by comparing their retention time with reference substances. The result showed that the amino acid constituents had a high similarity. Seventeen kinds of amino acids in elephant skin were detected. Conclusion: It is the first time to establish the HPLC fingerprint of elephant skin. The method is simple and quick, which provides the scientific basis for the comprehensive quality control of elephant skin.

Objective To compare the clinical results of femoral head replacement for femoral in- tertrochanteric fractures and femoral neck fractures in aged patients.Methods Forty cases of femoral in- tertrochanteric fractures and 45 cases of femoral neck fractures (aged over 80 years) underwent femoral head re- placement from August 1996 to April 2002 in our department.The clinical results of the two groups were retro- spectively compared and analyzed statistically.Their follow-up periods,ranging from 3 to 7 years,averaged 4.6 years in the intertrochanteric fracture group and 5.5 years in the neck fracture group.Results The differences in time of hospitalization,perioperative blood loss,postoperative drainage,ambulation trine,early compiications be- tween the two groups were of no statistical significance (P＞0.05).The differences in operation time and inequality in leg length after operation between the two groups were of statistical significance (P＜0.05).The operation time was longer and more limb-length inequality occurred in the intertrochanteric fracture group than in the neck fracture group.There was no significant difference in Harris score at the last follow-up between the two groups.The X-ray at the final follow-up showed that there was insignificant difference in postoperative hip joint space,hip pain,or stem loosening between the two groups (P＞0.05).The stem revision incidences were of no statistical significance be- tween the two groups (P＞0.05).The two groups reported no acetabular protrusion.Conclusion With standard cemented prostheses,femoral head replacements can achieve as similar functional outcomes for patients with in- tertrochanteric fractures as for those with femoral neck fractures.

Objective To investigate the protective effect of Xinyi capsule pretreatment on myocardial ischemia reperfusion injury in rabbits and its possible mechanism. Methods Ninety-four rabbits were randomly divided into 6 groups: model group (n=16), tirofiban group (n=16), high-, medium- and low-dose Xinyi capsule groups (4.0, 2.0, 1.0 g/kg;n=16 in each group), and sham operation group (n=14). Five days after intragastric administration with drug, myocardial ischemia reperfusion was induced by ligation of the proximal left circumflex artery. The electrocardiogram (ECG) was continuously recorded. The serum levels of myeloperoxidase (MPO), lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were measured. Myocardial histopathological damage was evaluated. Results The changes of J-point amplitude on ECG in high-, medium-and low-dose Xinyi capsule groups (0.064 ± 0.049 mV, 0.069 ± 0.061 mV, 0.079 ± 0.060 mV) were significantly lower than that in the model group (0.158 ± 0.105 mV, P<0.01 or P<0.05), the serum levels of LDH (399.7 ± 202.3 U/L, 369.6 ± 229.0 U/L, 435.5 ± 152.4 U/L), CK-MB (900.8 ± 231.2 U/L, 1 268.3 ± 899.8 U/L, 1 386.7 ± 621.6 U/L), MPO (69.81 ± 5.51 U/L, 85.44 ± 10.31 U/L, 81.33 ± 16.87 U/L) were significantly lower than those in the model group (LDH:817.1 ± 401.9 U/L, CK-MB:2 071.3 ± 693.5 U/L, MPO:149.9 ± 20.11 U/L;P<0.01 or P<0.05). Histopathological examination showed that myocardial damage in high-, medium- and low-dose Xinyi capsule groups reduced compared with the model group. Conclusions Xinyi capsule pretreatment can protect against myocardial ischemia reperfusion injury in rabbits, and its mechanism may be related to inflammation inhibition.
