Objective To investigate the effects of Xinnaoxuemianning combined with statins on carotid atherosclerotic plaque in patients with cerebral infarction. Methods 180 cerebral infarction patients were divided into the observation group (90cases) and the control group (90cases) by random number table method. The control group was given atorvastatin calcium tablets and the observation group was given additionally Xinnaoxuemianning. The changes and prognosis of carotid atherosclerotic plaques were evaluated before and after treatment, and the incidence of adverse reactions was counted. Results There were no differences in the carotid atherosclerotic plaque, TCM syndrome score and neurological deficit severity between the two groups before treatment. After treatment, the above indexes were significantly improved, and the increasing degree of the observation group was better than that of the control group. The incidence rate of adverse reactions was lower in the observation group than that in the control group (5.56％ vs.13.33％) (P<0.05). Conclusion Xinnaoxuemianning can reduce the carotid atherosclerotic plaque area and correct the unstable plaques in patients with cerebral infarction.

Objective To establish a HPLC method for determining and comparing the contents of diosbulbin B in
Dioscorea bulbifera L. from different regions. Methods The medicine powders were extracted twice by water, then the water extracts were combined and detected by HPLC at 35℃,with Kromasil-C18 column (4. 6 mm×250 mm,5μm) and a mobile phase of acetonitrile-water-glacial-acetic acid (34660. 1). The flow rate was 1. 0 mL·min-1 and the detection wavelength was 210 nm. Results The linear range of diosbulbin B was 26. 0-260. 0 μg·mL-1(r=0. 999 9). The average content of diosbulbin B in Dioscorea bulbifera L. from different areas was that of Hebei>Guangxi>Jiangsu>Sichuan>Zhejiang. Conclusion The method is simple,quick,accurate and suitable for the determination of diosbulbin B in Dioscorea bulbifera L. from different regions.

Objective To study cerebral cortical activation preoperatively and postoperatively in patients with cervical spondylotic myelopathy (CSM), and discuss effect of the surgery on cortical reorganization in functional recovery.Methods 19 cases with CSM intrial group underwent cervical vertebra canal decompression surgery according to clinical routine.Cases in trial group completed clinical assessment using the modified Japanese Orthopaedic Association Scores (mJOA) prior to decompression and 12 months following surgery, and underwent cerebral functional MRI and conventional MRI in the same time.19 controls also carried out cerebral functional MRI and conventional MRI.All subjects performed a finger-tapping paradigm with right hand during processing functional MRI.The imagings and data of trial group were divided into preoperative group and postoperative group in accordance with the time of completed and than analysed.Results The mJOA score of postoperative group was increased significantly (P<0.001).Cortical volume of activation (VOA) of preoperative group was significantly higher than the control group (P<0.05).VOA was lower in the postoperative group, but still significantly higher than the control group (P<0.05).The preoperative group was able to detect and activate the signal only in the left precentral gyrus.The postoperative group was able to detect and activate the signal in the l left postcentral gyrus, the premotor area and the supplementary motor area, and the right cerebral cortex could also detect a small amount of activation signal.Conclusion CSM patients undergo cerebral cortical remodeling, causing sensory and motor function activation areas to expand and shift.The changes of cortical reorganization after cervical vertebra canal decompression surgery are associated with functional recovery.The surgical treatment may promote the compensating cortical reorganization.

Objective To review the results of limb lengthening over an intramedullary nail in management of femoral defect and length discrepancy.Methods Femoral lengthening over an antegrade intramedullary nail was applied to treat length discrepancy of 4 to 7 cm for three cases,and femoral defects of 8 and 11 cm respectively for two cases from January 2001 to December 2003.The nail and an external fixator(Ilizarov external fixator for bone defect and Orthofix limb-reconstruction system for discrepancy)were applied concomitantly at the time of femoral osteotomy.After a mean fixation time of 16.2 days(13 to 24 days),gradual distraction began at a rate of 0.25 millimeter four times a day.When the managed femur reached the expected length,the nail was locked and the fixator was removed in patients with length discrepancy.The procedure was not finished in patients with bone defects until bony consolidation was partially seen.Results All the patients were followed up for a mean time of 36.4 months(range,22 to 47 months).The mean gain in length was 7.2 cm(range,4 to 10 cm)with good consoli- dation,the mean duration of external fixation was 5 months(range,3 to 8 months),and the mean external fixation index was 0.75 month per centimeter(range,0.57 to 1.00 month per centimeter).Neither axial deviation nor re-fracture occurred.At the last follow-up,the mean range of movement of knee was 107?(80?to 135?).Con- clusions In management of defect and length discrepancy of limbs,lengthening over an intramedullary nail has the advantages of short duration of external fixation,good protection against refracture,and earlier rehabilitation of knee joint,as well as disadvantages of long operation time,massive intraoperative bleeding,high cost and much post- operative scarring.

All the complications from 535 patients undergoing selective coronary artery angiogram by using Judkins method have been documented during and after the procedures and compared with collected data from Chinese papers published before 1999.The main complications included death, acute myocardial infarction,acute heart failure, severe arrhythmia,and peripheral vessel complication.In 535 patients the main complication rate was 2 99%(16 of 535),in which ventricular fibrillation rate accounted for 0 37%(2 of 535),severe bradycardia for 1 31%(7 of 535),and peripheral vessel complications for 1 31%(7 of 535).There was no death,no AMI, no heart failure,no artery embolus,no aortic dissection.Compared with 3 01% (141 of 4679) of complications for collected data from domestic literature,there was no significant difference.The data suggested that with effective preventive measures,coronary artery angiogram is a reasonably safe proceduce,although there is still a possibility to have server complications.

Compared with CT scan results of OSAS patients and normal adults to explore the value of CT diagnosis of upper airway stricture in patients with OSAS, 35 patients with OSAS and 35 normal adults were included in the study. 22, 19, 12, 8 cases had obstruction at palate, uvula, lingua and epiglottis region respectively, the awaked CT scan results of 61 obstructive sites were compared with those of normal adults. Obvious difference was found between patients and normal adults in area, left right dimension and coronal dimension. difference was also found in thickness of lateral pharyngeal tissue of palate, uvula and lingua region and retropharyngeal tissue of palate and uvula. The normal extent was determined by unilateral 95% confidence interval in normal adult group. And 43 sites had abnormal CT scan results, the positive ratio was 72 13%. The results sugget that there are obvious differences between the patients with OSAS and normal adults, the CT scan measure can show the upper airway obstructive site of patients with OSAS.

Objective To compare the immune protective effects of three antigens of Trichinella spiralis encapsulated larvae on mice.Methods The mice were immunized with Trichinella spiralis encapsulated larvae somatic antigen,encapsulated larva excretory-secretory antigen and encapsulated larva surface antigen,3 times with a 7-day interval,and the adjuvant control and normal control group were set up.Seven days after the final immunization,each mouse was orally challenged with 200 Trichinella spirais larvae.The intestinal adult worms and muscle larvae of Trichinella spiralis of each group were recoveried and examined on Day 7 and Day 30 post-challenge,respectively.The level of 8eruln IgG to antigens of Trichinella muscle muscle larvae wa8 detected by ELISA.Results The intestinal adult worms were reduced by 84.89%.89.73%,85.65%.2.57% in the encapsulated larva somatic,excretory-secretory and surface antigen groups,respectively.The muscle lalwae were reduced by 71.71%,80.98%,73.66%,5.60%, respectively.Adtlltwornl reduction rates(P<0.05) and musclelarva reduction rates(P<0.01) of the encapsulated larva excretory-secretory antigen group and surface antigen group were higher than those of encapsulated larva somatic antigen group.The antibody titers in all the immunized groups increased significantly.and the GMRT values of the encapsulated larva somatic,excretory-secretory and surface antigen groups were 32 798.89,3 474.51,2 984.83,respectively,and were 6.09,7.56,6.50 times higher than those of the normal control group(459.32).Conclusions Trichinella spiralis encapsulated larva antigens can induce strong resistance of host to a subsequent challenge infection.Among these antigens,excretory-secretory antigen is more immunogenic.
