Object To investigate the effect of total flavone in Sanguis Draconis (tFSD) on platelet aggregation, thrombus formation and myocardial ischemia in rat and rabbit. Methods Adopting the experimental models including in vitro platelet aggregation in rat and rabbit, in vivo thrombus formation in rat internal vein, and acute myocardial ischemia by ligating the coronary artery. Results In vitro, tFSD could, to a certain degree, inhibit the platelet aggregation induced by ADP and PAF. Moreover, tFSD could markedly restrain artificial thrombus formation in rat internal vein and the area of acute myocardial ischemia after ligating the coronary artery. Conclusion tFSD has the function of promoting blood circulation and removing blood stasis, anti thrombosis, together with platelet aggregation inhibition.

Objective To explore the protective efficacy of antioxidants (vitamin E and Ginkgo biloba extract) on the peripheral nerve damages induced by antiepileptic drugs (AEDs). Methods Adult (2-month old) and infant SD rats (7-day old) were respectively treated with AEDs (phenytoin,or phenobarbital,or clonazepam) alone,or simultaneously with vitamin E or Ginkgo biloba extract for 4 weeks. All the rats were sacrificed,sciatic nerves and serum were collected. The sciatic nerves were analyzed by histologically for their pathological changes,and serum and homogenate of sciatic nerves were investigated for their total antioxidative capacity and antioxidant enzyme activity. Results Incidence of pathological abnormalities of teased fibers significantly reduced in all rats treated with AEDs and antioxidants (P

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.

Objective To explore the clinical usage of allograft vessels for portal venous reconstruction during radical resection for pancreatic cancer.Methods We retrospectively analyzed clinical data of 14 patients who underwent pancreaticoduodenectomy with vascular resection (PDVR) and reconstruction by allograft vascular form June 2009 to May 2013.Results Patient's mean age was (59.1 ±10.4) years old.The mean diameter of tumors was (3.9 ± 1.3) cm,mean lcngth of resected vessels was (4.4 ±0.5)cm,and the R0 resection rate was 71.4%.The implanted vessels in 4 cases were allograft portal veins,and in the other 10 cases were allograft iliac arteries.In morphological classification,9 cases used straight vessels and 5 cases used Y shaped vessels.The overall median survival time of the group was (14.0 ± 3.0) months.The 1,2 year' s survival rate was 52.0% and 40.0%,respectively.Conclusions Allograft vessels for portal venous reconstruction during PDVR have biological and structural advantages.

Objective To investigate the pathological features of sural nerve biopsy in patients with motor neuron disease (MND). Methods 22 patients with amyotrophic lateral sclerosis (ALS) underwent sural nerve biopsy and routine electrophysiological examination. The transected images were captured and morphometrically analyzed.Results The myelinated fiber density decreased in ALS patients' sural nerves, and larger fibers were involved mostly. The thinly myelinated fibers increased. Conclusion The sural nerves of ALS patients shows mild but definite pathological changes.

Objective To study the value of carotid plaque magnetic resonance imaging (MRI) in pre-operation assessment in the elderly patients with carotid atherosclerosis and explore the possibility of minimizing the contrast weightings to gain sweeptime. Methods Totally 70 elderly patients with cerebral ischemia (average age of 68.8 years) underwent carotid MRI and digital subtraction angiography (DSA) due to the appearance of carotid plaque detected by ultrasound. Carotid plaque MRI was acquired with 3.0T MR scanner and 8 channel surface coil. The standard carotid plague MRI program included pre-and post-contrast T1 weighted imaging (T1WI), T2 weighted imaging, proton density weighted imaging and 3D time of flight MR angiography (3D TOF MRA). All these program were divided into two combinations: the 5-sequence MRI (all the sequences) and 2-sequence MRI (T1WI and TOF MRA). Digital subtraction angiography (DSA) in coronal and lateral views of carotid artery was performed with GE Advantx LCN+. The software SPSS 13.0 was used to statistically analyze the difference between MRI and DSA, and that of two sequence combinations was used in the detection of luminal stenosis and fibrous cap (FC) rupture. Results Totally 135 arteries were analyzed while 3 arteries in one patient were excluded due to the poor quality image and stent placement. The degree of luminal stenosis were (38.3±31.0)% and (38.5±30.9)%, respectively, detected by the two MRI sequence-combination with no significant difference (t=2.447, P>0.05) and was (35.1±31.8)% by DSA. There was a good concordance between MRI and DSA in luminal stenosis detection (Kappa value: 0.773). No statistical difference was found between two MR sequence combinations in detecting FC rupture (both in 36 vessels). DSA detected FC rupture of 16 vessels, showing remarkably difference contrast to MRI(χ2=12.0, P<0.01). Conclusions MRI can accurately detect the luminal stenosis and FC rupture. The short time scanning resulting from sequence optimization could make MRI much more suitable than DSA to do the pre-operation assessment for senile carotid atherosclerotic patients.
