To probe tentatively into the relations of Terminalia chebula Retz., Terminalia billerica (Gaertn.) Roxb, and Phyllanthus emblica L. between TCM and Tibetan medicine. Methods　Textual researches of materia medica were carried out and their history in clinical application were traced. Results　T. chebula, T. billerica, P. emblica were all of foreign origin and were introduced into China with Buddhism. As compared in medical practice, the Tibetan autonomony region has their particular choice and preference. Conclusion　We should apply modern scientific research achievements to carry out deep mutual exchanges to enrich TCM.

Objective To develop an assay of HPLC for the content determination of dryocrassine in Guanye Jinsitao drop pills. Methods The column was Kromasil-C18 (150 mm×4.6 mm, 5μm);mobile phase was acetonitrile-chloroform-isopropanol-0.1% phosphoric acid (52∶8∶30∶10);flow rate was 1.0 mL/min;UV detection was performed at 285 nm;detected drift tube temperature was set at 25 ℃. Results The calibration curves were linear in the range of 0.236-2.124 μg for dryocrassine (r=0.999 9). The average recovery rate of dryocrassine was 99.64% (RSD=1.90%). Conclusion The method is simple and accurate. It is suitable for the determination of dryocrassine in Guanye Jinsitao drop pills.

Objective To observe the influence of intensive insulin therapy on inflammatory fac-tors and prognosis in severe multiple trauma patients.Methods A total of 53 cases of severe multiple trauma were randomly divided into the treatment group(n =27)and the control group(n =26).Besides basic treatment,patients in the treatment group received additional intensive insulin therapy by micro-pump.The level of blood glucose in the control group was controlled under 11.1 mmol/L.Levels of TNF-α,IL-1β,IL-6,and CRP were tested before and after treatment.Multiple organ dysfunction syndrome,noso-comial infection rate,and mortality rate were also observed.Results The levels of TNF-α,IL-1β,IL-6, and CRP in the treatment group were significantly lower than those of the control group(P <0.05 or P <0.01).The incidence of multiple organ dysfunction syndrome,nosocomial infection,and mortality rate in the treatment group was lower(P <0.05).Conclusion Intensive insulin therapy can effectively decrease the expressions of inflammatory factors in patients with severe multiple trauma,improve the prognosis,re-duce the incidence of nosocomial infection and mortality.

The Proposal for the Standardization of Urinary Sediments Examination and the expert consensus have provided effective and timely instruction on urinalysis normalization,but there are still some puzzles about the methods and requirements on quality improvement for urinalysis normalization.This paper is discussing about some issues referring to American and European urinalysis guidelines,which include establishment of examination procedure,specifications and methods of testing system evaluation,specimen stability,the influence of sample centrifugation,the usage of sample staining,confirmation tests,requirements on result reporting,internal quality control and external quality assessment.These discussions will contribute to the quality improvement of urinalysis in clinical laboratories.

Objective To provide data support for safe and accurate lower cervical pedicle screw implantation by observing the lower cervical pedicle and its relationship between the adjacent spinal cord, endorhachis, nerve root and vertebral artery, particularly its relation-ship between the endorhachis and epidural sinus. Methods Measured the C3 ~ C7 cervical sample of 32 adult with vernier caliper and pro-tractor, including the distance between cervical pedicle and its upper and lower nerve root, the distance between cervical pedicle and en-dorhachis, the distance between cervical pedicle and vertebral artery, and the distance between cervical pedicle and epidural sinus. Results The distance betweencervical pedicle and its upper nerve root was 1. 18~1. 40 mm, the distance between cervical pedicle and its lower nerve root was 2. 33~3. 11 mm;the distance between cervical pedicle and endorhachis was 2. 75~3. 33 mm;and there was nearly no distance be-tween cervical pedicle and vertebral artery and epidural sinus. Conclusion Cervical pedicle has a very close relationship with spinal cord, endorhachis, vertebral artery and nerve root, and the cervical pedicle is narrow and small. Therefore, it requires fully assess accroding to in-dividualization so as to prevent injury of important anatomical structures.

OBJECTIVE:To systematically review the procalcitonin(PCT)-guided therapy in patients with sepsis. METHODS:Retrieved from PubMed,Cochrane Library,EMBase,CJFD,Wanfang Datebase,related trails about PCT-guided therapy(test group)versus conventional treatment group(control group)in the treatment of sepsis were collected. Meta-analysis was performed by using Rev Man 5.3 software after data extraction and quality evaluation. RESULTS:Totally 5 studies were enrolled,involving 826 patients. Results of Meta-analysis showed,use time of antibiotics in test group was significantly shorter than control group, with statistical significance [MD=-2.52,95%CI(-3.07,-1.98,P<0.001];there were no significant differences in the mortality rate [OR=1.14,95%CI(0.83,1.56),P=0.42],ICU treatment days [MD=-0.22,95%CI(-1.40,0.96),P=0.72] and total hospi-talization [MD=-1.81,95%CI(-4.37,0.76),P=0.17]. CONCLUSIONS:PCT-guided therapy can effectively reduce the use of antibiotics and shorten treatment time in the treatment of patients with sepsis.It can be considered as inflammatory markers for guid-ing rational use of antibiotics in clinic.

Punicalin is an important ellagic tannin in Pericarpium Granati with the pharmacological effects such as antioxidation,anti-bacteria,antivirus and anti-inflammation.The studies on Pericarpium Granati at home and abroad were reviewed in the paper,and the extraction,separation,content determination,pharmacological activities and metabolism of punicalin were also summarized to provide theoretical basis for the development and application of punicalin.

Objective To understand the status and developmental trends of the research on anterolateral thigh flap. Methods The PubMed search was downloaded and the results were imported into the EndNote database,then the distribution was analysed by age,nation,language,periodical and frequency.Results There were 236 articles on anterolateral thigh flap in PubMed from 1996 to August 2006.The amount of articles multiply increased from 2002 to August 2006,at eighty percent of all.They were published in 8 languages,in 47 journals and from 9 countries.China and the USA are the major countries of the publication,with 77 articles each,which altogether took up 65.2% of the total.Words of a high frequency are as follows: free skip flap,island skin flap,ultrathin skin flap,perforating artery,and descending branch of lateral circumflex femoral artery,the frequency ratio of which is up to 97.46%.Conclusion The papers on anterolateral thigh flap are written mainly by China and USA;English is the main publishing language;The articles are chiefly published by Plast Reconstr Surg and other 8 journals.The research emphases of the anterolateral thigh flap are on free skip flap,perforating flap,ultrathin skin flap,and island flap.Angiography and 3D-reconstruction are the recent techniques for the research.
