AIM:To establish a HPLC diagitized fingerprint for Ixeris sonchifolia Hance Injection to serve as a digitized method criteria for its overall quality control. METHODS: The chromatographic fingerprints were obtained by injecting 20 ?L of the sample solution each time on a Century SIL BDS column (250 mm?4.6 mm, 5 ?m) with the gradient elution solvent system composed of 1% acetic acid water and 1% acetic acid acetonitrile. The flow rate was 1 mL/min, the column temperature was maintained at (30?0.15)℃ and the detection wavelength was set at 265 nm. The chromatographic fingerprints were charateristically digitized and evaluated by the software of the digitized evaluation system of traditional Chinese medicine fingerprint with the super information characteristics to give the 42 parameters such as chromatographic fingerprint index (F), chromatographic fingerprint resolution index (RF), which could thoroughly disclose the hidden information in the fingerprints. Meanwhile, the apparent molecular weight, the peak position, the elution fore index and the pseudo peak area were marked in terms of the principle of QSPR when the two peaks were selected as the reference peaks. RESULTS: 21 co-possessing peaks were selected as the fingerprint peaks of Ixeris sonchifolia Hance Injection by taking caffeic acid peak as the reference peak to establish the digitized fingerprint and obtain the important digital information about its quanlity control. The stabilities among different batches of samples were evaluated by the dual qualitative and dual quantitative similarity method. CONCLUSION: This new digitized fingerprint method with good precision and reproducibility can be perfectly applied to the quality control over Ixeris sonchifolia Hance Injection. Digitized fingerprint obtained from the dual qualitative and dual quantitative similarity method maybe extend further to assess and control the quanlity of TCM.

Objective Thermal burns of the anterior chest disfigure the female breast, and the postburn breast deformity is a sequela of severe scar contraction of the burned chest. For deformities that affected the mammary development, museulocutaneous flaps were used. Here we introduce our experience in using the latissimus dorsi myocutaneous island flap in burned breast reconstruction. Methods During the past 7 years, 7 female patients with such deformities required reconstruction, the expanded or unex-panded latissimus dorsi musculocutaneous island flaps were used in the partial reconstruction of burned breast. In the mild deformities group (2 cases), unexpanded latissimus dorsi musculocutaneous island flaps were used. For patients with undeveloped mammary glands (5 cases), expanded latissimus dorsi musculocutaneous island flaps were used. Results The procedure was performed in 7 patients and all the flaps were alive, with significant improvement of breast appearance. The complication rate was low. There were no deformity and dysfuction in the donor site. Conclusions The technique has many advanta-ges: beautiful contour of breast, good blood supply of the flap, no donor site morbidity. It provides the plastic surgeon with an excellent, safe and consistently successful method for burned breast reconstrue-tion. This experience has led to development of surgical principles and techniques tailored to this particu-larly difficult problem.

Objective To study the clinical effect of qi supplementation combined with rehabilitation on the severity of fatigue after ischcmic stroke in patients with qi deficiency. Methods Ninety ischemic stroke patients with qi deficiency were randomly divided into 3 groups of 30. The treatment group was treated with an oral decoction of qi-supplementing Chinese medicine and also rehabilitation. The Western medicine control group was treated with a Chinese medicine placebo, Western medicine and rehabilitation. The blank control group was treated with the Chinese medicine placebo and rehabilitation. All groups were evaluated using a stroke-specific quality of life scale ( SSQOL) and a fatigue severity scale (FSS) before and 4 weeks after treatment. Results After treatment, the average SS-QOL and FSS scores had improved significantly compared with those before treatment, especially in the two treatment groups. There was a significant difference between the treatment group and the Western medicine control group,and between the treatment group and the blank control group on both scales. There was also a significant difference between the Western medicine control group and the blank control group in terms of SS-QOL scores, but not FSSscores. Conclusion All 3 treatments alleviated fatigue in ischemic stroke patients with a qi deficiency. Qi supplementation combined with rehabilitation was the most effective, followed by Western medicine combined with rehabilitation.
