Based on the infrared spectra of Lophatheri Herba and Commelinae Herba, one-dimensional infrared spectra, second derivative spectra and two-dimensional correlated spectra were used to find out the differences between Lophatheri Herba and its imitations, respectively. The common peak ratio and variant peak ratio dual-indexes sequential were calculated and established according to infrared spectra of eleven batches of herbs. Infrared spectral data of Lophatheri Herba cluster analysis was applied to explore the similarity between each sample. The grouping results trend of sequential analysis of dual-indexes and cluster analysis was accordant. The results showed that the differences could be found by multi-level identification, and the source and the quality of the herbs could be effectively distinguished by the two analysis methods. Infrared spectroscopy, used in the present work exhibited some advantages on quick procedures, less sample required, and reliable results, which could provide a new method for the identification of traditional Chinese medicine with the imitations and adulterants, and the control of quality and origin.

OBJECTIVETo study the curative effect of postural reduction with instrumental reduction in treatment of flexion-distraction thoracolumbar fractures.
METHODSA retrospective study was performed on 43 patients with single thoracolumbar flexion-distraction fractures admitted from August 2009 to August 2011, included 28 males and 15 females with an average age of 44 years old (34 to 56 years old). All patients were treated with postural reduction with instrumental reduction. The kyphosis (Cobb angle) recovery of injured vertebral height and complication were analyzed. The visual analogue scale(VAS) and com-plications were followed up and recorded.
RESULTSThere was no difference in recovery of injured vertebral posterior height among preoperative, 1 week and 1 year after operation (P > 0.05). There were significantly difference in kyphosis (Cobb angle) and recovery of injured vertebral anterior height between preoperative and postoperative at 1 week (P < 0.05). There was no difference in kyphosis (Cobb angle) and recovery of injured vertebral anterior height between 1 week and 1 year after operation (P > 0.05). VAS significantly improved from preoperative (7.2 +/- 1.2) to (0.8 +/- 0.7) at 1 year after operation (t = 18.47, P < 0.001).
CONCLUSIONPostural reduction with instrumental reduction is effective for thoracolumbar flexion-distraction fractures and it is beneficial to the recovery of vertebral height and saggital alignment.

Objective To present the experience of laparoscopic extraperitoneal radical prostatectomy and evaluate its safety and efficacy. Methods A total of 91 patients diagnosed with localized prostate carcinoma were admitted from February 2003 to June 2008. The level of serum PSA ranged from 7. 5 - 47. 0 ng/ml(mean 14. 0 ng/ml). The volume of the prostate ranged from 35 - 75 ml(mean 52 ml). Biopsy was performed before the operation and the pathological results revealed prostate carcinoma with Gleason score no more than 8. CT, MR and ECT revealed there was no lymph node or seminal vesicle involvement and there was no bone metastasis. The procedures were performed with an-tegrade techniques and pelvic lymphadenectomies were performed in 32 cases and nerve-sparings were performed in 11 cases. Results The operation duration ranged from 105 - 270 min (mean 173 min). Intraoperative blood loss was 110 - 1200 ml(mean 315 ml). Incontinence occurred in 19 cases in early stage and 18 cases recovered within 3 months. Positive surgical margin occurred in 11 cases. There was no complication of urethra stricture during 3 - 30 months' follow-up. No lymph node was involved in 32 cases with pelvic lymphadectomy. Five of the 11 cases received nerve-sparing prostatectomy had normal erectile function during the follow-up. Conclusions Laparoscopic extraperitoneal radical prostatectomy is a safe, effective and efficient surgical procedure with the minimal invasion, less morbidity and rapid recovery. Laparoscopic radical prostatectomy is emerging as an alternative to open radical prostatectomy.

The paper summarizes the interactions between luteolin (glucosides) and drug-metabolizing enzyme from the literature of recent years and our research work. The metabolism of luteolin is chiefly mediated by phase II metabolic enzyme. Its glucosides are firstly hydrolyzed into aglycone in intestinal tract, and then absorbed and metabolized. Luteolin has the effect on the induction of CYP3A, and on the inhibition of CYPIA, 1B and 2E. Also, luteolin is an effective inhibitor of CYP2B6, CYP2C9 and CYP2D6. Luteolin can induce and inhibit UGTs and SULTs. It can also inhibit multi ABC transport proteins. Understanding the interactions between luteolin (glucosides) and drug-metabolizing enzyme has an important significance in guiding clinical use of the drug.
