AIM: To develop an HPLC method for determintion of alliin concentration in rat plasma and to study its pharmacokinetics in rat. METHODS : The plasma samples were extracted with methanol. The analysis involved a ODS-1 column as stationary phase and distilled water as mobile phase. The flow rate was 0.5mL?min -1 ,UV detection wavelength was at 220nm. 5-fluorouracil was used as the internal standard. RESULTS : The calibration curve was linear over the range from 3?g?mL -1 to 75?g?mL -1 with a correlation coefficient of 0.9989 . The mean recovery was 95%. The RSD of within-day and between-day were all less than 5%. The HPLC method of determination of alliin in the plasma was established. After single dose of 300mg?mL -1 in 6 rat,the main pharmacokinetic parameters were estimated to be as follows: CL( 0.048 )mg?min -1 ?kg -1 ,K_ 12 ( 0.0071 )min -1 ,K_ 21 ( 0.0093 )min -1 ,K_a(0.1915)min -1 ,t_ 1/2? ( 26.85 )min -1 ,t_ 1/2? ( 131.15 )min -1 , AUC( 6228.48 )?g?min -1 ?mL -1 . CONCLUSION : This method is quick,precise and reliable. It is shown that alliin is absorbed quickly in rat.

OBJECTIVETo explore the surgical method and its clinical effects of minimally invasive osteosynthesis on the treatment of complex ankle fractures.
METHODSFrom January 2007 to December 2011, 53 patients with complex ankle fractures were treated with minimally invasive osteosynthesis. There were 31 males and 22 females, with an average age of 38.2 years old (ranged, 18 to 65). According to the system of Lauge-Hansen, 32 fractures were supination external rotation injury (grade WV), 13 fractures were pronation external rotation (grade III or IV), 5 fractures were pronation abduction (grade III); and 3 fractures can not be classified due to serious comminution fracture of fibula. According to the system of Denis-Weber, there were 4 cases with type A, 34 cases with type B and 15 cases with type C. Seven cases were open fractures. The duration from injuries to operation ranged from 2 hours to 14 days with an average of 5 days. The sequence of reduction and fixation of ankle fractures was firstly posterior malleolus, then medial malleolus and lateral malleolus, and inferior tibiofibular syndesmosis lastly. The fractures of posterior malleolus were reduced and fixed through anterior ankle approaches; the fractures of medial and lateral malleolus were percutaneously fixed with bolts or blade plate or tensile force band; and inferior tibiofibular syndesmosis were firmly fixed if necessary. Baird-Jackson scoring system was used to evaluate clinical effects.
RESULTSForty-eight patients were followed up from 10 to 36 months with an average of 13 months. The fractures got healing with an average time of 12 weeks (ranged, 10 to 18). According to the Baird-Jackson scoring system, the mean score of ankle function was 94.7 +/- 4.2, and 28 cases obtained excellent results, 15 good, 3 fair and 2 poor. One case experienced superficial infections and was cured by changing dressings, 2 cases experienced fixed syndesmosis screw breakage.
CONCLUSIONThe surgical method of minimally invasive osteosynthesis can ensure the anatomical join restoration, protect the blood supply of fracture end, rebuild the function of ankle joint, obtain satisfactory clinical results in treating complex ankle fractures.

OBJECTIVETo compare the differences in the clinical efficacy on post-stroke speech disorder between scalp electric acupuncture (EA) under anatomic orientation combined with rehabilitation training and simple rehabilitation training.
METHODSSixty patients of post-stroke speech apraxia were randomized into an observation group and a control group, 30 cases in each one. In the observation group, under anatomic orientation, the scalp EA was adopted to the dominant hemisphere Broca area on the left cerebrum. Additionally, the speech rehabilitation training was combined. In the control group, the speech rehabilitation training was simply,used. The treatment lasted for 4 weeks totally. The speech movement program module in the psychological language assessment and treatment system of Chinese aphasia was used for the evident of efficacy assessment. The scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were observed in the patients of the two groups. The assessment was done separately on the day of grouping and 4 weeks after treatment.
RESULTSIn 4 weeks of treatment, the scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were all improved as compared with those before treatment in the two groups (all P<0. 001). The results in the observation group were better than those in the control group (all P< 0. 05). The total effective rate was 100. 0% (30/30) in the observation group, superior apparently to 53. 3% (16/30) in the control group (P<0. 001).
CONCLUSIONThe scalp EA under anatomic orientation combined with' speech rehabilitation training obviously improves speech apraxia in stroke patients so that the speech disorder cani be relieved. The efficacy is better than that in simple rehabilitation training.

There are few articles or reports collecting evidence about parenterally administered salvianolate from premarketing and postmarketing research or studies systematically. This article is an exact miniature of a systematical report about parenterally administered salvianolate. We analyzed information from four aspects, such as quality control reports, non-clinical premarketing safety experiments, postmarketing research (efficacy studies, hospital information system data and national spontaneous reporting system data) and literature analysis. All the four aspects build an evidence body for Kudiezi Solution in order to inform its safety use in clinical practice and further study.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy combined with limited open repair of medial collateral ligament (MCL) for the treatment of multiple ligament injuries of knee joints.
METHODSFrom March 2006 and June 2012,the data of 14 patients (14 knees) with multiple injuries of ACL, PCL, and MCL were collected. There were 8 males and 6 females with an average age of (31.8 +/- 8.1) years old (ranged, 20 to 49 years old). All the patients were performed with X-ray and MRI examination, and the results showed that 10 patients had combined with injuries of anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL); 4 patients had ALC,PCL and posterolateral corner (PLC) injuries. Four patients had medial meniscus injuries and 2 patients had lateral meniscus injuries. The MCL,PLC and meniscus injuries were treated with operation on the first stage, and functional exercises were performed 3 weeks after fixation. The reconstruction operation of ACL and (or) PCL was performed at the second stage under arthroscopy 3 to 6 months later when the movement range of knee joint recovered to the normal level with obvious relaxation.
RESULTSAll incisions healed by primary intention. All the patients were followed up with a mean duration of 48.9 months (ranged, 24 to 80 months). The Lysholm score was improved from preoperative 19.6 +/- 0.9 to the latest follow-up 87.1 +/- 2.8 (t=12.3, P<0.01). The International Knee Documentation Committee (IKDC) rating: 9 cases nearly recovered to normal, 5 cases were abnormal.
CONCLUSIONFor multiple ligament injuries in the knee, staged repair and reconstruction can effectively restore knee joint stability and function.

To assess the left ventricular regional relaxation abnormalities in patients with hypertrophic cardiomyopathy (HCM) by quantitative tissue velocity imaging (QTVI), Doppler echocardiography and QTVI were performed in HCM (n=10) and healthy subjects (n=11) at apical long-axis, two-chamber and four-chamber views. Regional early diastolic velocity (rVe) and regional atrial contraction (rVa) were measured at each segment of ventricular middle, basal and annular levels. Mean rVe and mean rVa at three levels as well as mean rVe/rVa ratio were calculated. Our results showed that transmitral inflow peak velocities during early diastole (E) and atrial contraction (A) were also measured and E/A ratio was calculated. The rVe of all left ventricular segments in HCM were lower than those in healthy subjects (P<0.05), but compared with healthy subjects majority of rVa in HCM were not different except inferior wall and anterior wall. E between HCM and healthy subjects was different (P=0.036), while mean rVe between them was significantly different (P<0.0001). Mean rVa and mean rVe/rVa of three levels were lower in HCM than in healthy subjects (P<0.05), but there were no differences in A and E/A between them (P=0.22, P=0.101). Left ventricular regional myocardial relaxation is reduced in HCM. Transmitral inflow E and A are influenced by preload, relaxation of myocardium and atrial contraction, etc., while rVe and rVa reflect myocardial relaxation function independently. QTVI is more sensitive and more accurate than conventional Doppler imaging for characterizingregional diastolic properties in HCM.
