In this paper, Fourier transform infrared spectroscopy fingerprint analysis of Marsdenia tenacissima samples was used to develop a reliable method of tracing the geographical origins. Forty-eight samples from four provinces of China were analyzed by FTIR. We analyzed and characterized the fingerprints in both the full spectrum peaks and characteristic peaks, then the principal component analysis and the cluster analysis were carried out. The results of fingerprint analysis, correlation analysis, principal component analysis and cluster analysis can identify the geographic origins correctly, which verified and supplemented each other; the identification results and the actual location showed a high degree of consistency, namely the lower the space distance, the greater the similarity of different samples. These results revealed the obvious superiority and practical value in comparison to the more tedious and time-consuming wet chemistry method normally used. Using appropriate metrology methods can trace the geographical source correctly. The M. tenacissima materials from the region of Maguan should be considered as genuine medicinal materials taking into account the good quality.

Mouthpart developmental histology of Whitmania pigra at different month of age were studied by paraffin section, HE staining combined alcian blue and periodic acid schifts reaction procedure (AB-PAS). The following results was obtained: Change ranges: oral width 0.6 mm (1-3 month), 1.2 mm (34 month); oral diameter 0.3 mm (1-3 month); 1.2 mm (34 month), the oral size reached maximum during 4-6 months and unchanged thereafter. Oral lip had a thin protective film located in the front of the mouthpart. The W. pigra possessed three jaws in oral cavity, the big one was in dorsum, the other two separated on both side of abdomen respectively. Jaws and muscular pharynx were interrelated closely. The jaws were composed by cuticle, epithelial layer, muscularis and jaw cavity from outside to inside. In the front of jaws had mastoid abdomen with function of secreting acidophilic granule from 2 month age. Oral cavity was composed by mucosa, submucosa and muscularis inside and outside. Oral cavity was rich of peristomial nerves. And pharynx was composed of mucosa, muscularis, adventitia from inside to outside. The folds height and width become heighten and thicken. Mucosa epithelium from complex flat epithelium changed into columnar epithelium, muscularis gradually developed into thickened along with growing. Muscular thickness reached maximum at 4 months. Mucous cells of W. pigra were classified into I-IV types based on different staining and two mainly morphological shapes (Tubular, Pear-shaped). Jaws, oral cavity, pharynx by AB-PAS staining showed little changes at different month of age. Mucous cells were few at 1 month age, and type II cells were increased rapidly in 2-3 month age in oral lip. Oral cavity contains more mucous gland cells type I. Under the muscularis there were connective tissues which distributed a few of mucous cells type II.

BACKGROUND:Intensity-time (I/T) curve examination is a monitoring technology used for diagnosis of nerve damage,muscle disease and prognostic evaluation using current stimulation and qualitative or quantitative analysis.It also has significance to the diagnosis of lumbar disc herniation (LDH).Whether it can be used in LDH prognostic evaluation is poorly understood.OBJECTIVE:To explore the effectiveness of I/T curve in diagnosis and prognostic evaluation of LDH.METHODS:I/T curves of 113 LDH patients were measured by CX-3 electrodiagnostic equipment,and the results were compared with their unaffected sides and analyzed after physiotherapy.A total of 253 curves were measured,including 107 biceps femoris,101 gastrocnemius and 45 tibialis anterior muscle curves.All patients were sequential treated by traction,medium frequency,ultrashort wave,electric acupuncture as well as infrared radiation following I/T diagnosis,once a day,10 days for a course,with 10 days interval in 3 courses,I/T curves were performed after 3 courses.The therapeutic effect was evaluated by using I/T results combined with clinical symptom and physical signs.RESULTS AND CONCLUSION:The first estimated percentage by I/T curved line were 36.36% (controlled by normal nerve),62.85% (controlled by part of the denervated),0.79% (controlled by the completely denervated) and 63.64% (controlled by total abnormal nerve).After the physiotherapy,the effectiveness of the complete recovery was 92.86% by the normal nerve as well as 58.82% by the abnormal nerve.Above all,the practical value could be concluded from the diagnosis,evaluation and effectiveness of LDH used by I/T curve line.The therapeutic effectiveness controlled by the normal nerve is much better than that controlled by the abnormal.

Objective To study the clinical application of finger reconstruction by transplantation of two second toes and evaluate the postoperative appearance and function regarding the reconstructed hand and donor feet. Methods Defect of fingers were treated by transplantation and reconstruction with a total of 74 cases,including two second toes transplantation for both thumbs in 2 cases,thumb with index finger in 10 cas es, index finger with middle finger in 8 cases and middle finger with ring finger in 17 cases. Results Sevetythree fingers survived except 1 failed. During the follow up examination made from 3 to 36 months, the reconstructed fingers could move, write and dress with ease, pinch forcefully, show good recovery of manual work and the sensation of pain and warmth. Two-point discrimination found to be between 5 to 10 mm. Both donor feet have symmetrical appearance with normal gait and satisfactory motion. Also, no pain was complained.Conclusion Transplantation of two second toes from both feet is a good method to reconstruct defect of multiple fingers, and has little effect on the appearance and motion of feet.
