BACKGROUND: Previous studies showed that the prevalence and extent of carotid artery stenosis increased with thedevelopment of coronary artery disease. There was a higher incidence of intracranial small-vessel disease, but lower of carotid artery disease in the Chinese stroke patients as compared with the white.OBJ ECTIVE: To observe the distribution of carotid and intracranial artery stenosis in patients with 3-vessel coronary artery disease.DESIGN: An observational study.SETTING: Department of Neurology; Heart Center, Beijing Chaoyang Hospital affiliated to Capital Medical University.PARTICIPANTS: From August 2003 to August 2004, The coronary angiography was performed in the outpatients and inpatients suspected to be coronary arteriosclerotic cardiopathy in the Department of Neurology, Beijing Chaoyang Hospital affiliated to Capital Medical University, and 126 patients of them with 3-vessel diseases were examined with carotid arteriography, including 56 males and 70 females, 47-76 years of age. Informed contents were obtained from all the participants.METHODS: Digital substraction angiography (DSA) was performed immediately after coronary angiography in the 126patients. All catheterizations were performed through a transfemoral approach using the Seldinger technique, and thenan appropriate amount of nonionic Ominipaque was injected. The angiography of bilateral carotid arteries, subclavian artery, or vertebral artery was taken from different angles. The percentage of stenosis was calculated directly from DSAmachine. Evaluative standards: Based on the stenosis degree from carotid angiography results, the patients were divided into 5 categories as normal, mild stenosis, moderate stenosis, severe stenosis and complete occlusion.MAIN OUTCOME MEASURES: Severity of carotid stenosis.RESULTS: All the 126 patients were involved in the final analysis of results. There were 13 (10.32%), 18 (14.29%), 12(9.5%), or 10 (7.9%) patients found to have mild, moderate, severe carotid stenosis, or complete occlusion, and the incidences of these changes were fairly similar. However, the incidence of angiographic carotid stenosis coupled with 3-vessel carotid artery disease was 42.06%.CONCLUSION: The prevalence of carotid stenosis in patients with 3-vessel carotid artery disease was as high in the Chinese population as that in Westem countries. In patients with 3-vessel disease, the prevalence of carotid stenosis was higher than that of intracranial artery stenosis, thus they may require both coronary and carotid interventions.

?AIM: To retrospectively analyze the surgical strategies and outcome of traumatic lens dislocation.?METHODS: Retrospective study. Clinical data of 105 cases ( 105 eyes ) diagnosed with traumatic lens dislocation from April to June 2014 in our hospital were recruited. According to position of dislocated lens and complicated situations, different surgical approaches were performed, including intracapsular lens extraction, phacoemulsification, vitrectomy through pars plana and lensectomy. Meanwhile, vitreo-retinal or anti-glaucoma surgeries were performed in complicated cases. Preoperative and postoperative LogMar ( Logarithm of the Minimum Angle of Resolution ) visual acuity were compared by paired t-test. Perioperative complications including expulsive choroidal hemorrhages and recurrent retinal detachment were recorded and assessed.?RESULTS: All 105 dislocated lenses were removed completely. Visual acuity of 91 eyes ( 86. 7%) were significantly improved postoperatively. The visual acuity of most patients was 0. 1-0. 3 ( 42 eyes, 40. 0%) and 1 patient’s visual acuity with lens subluxation reached more than 0. 8 postoperatively. Expulsive choroidal hemorrhages occurred in 1 eye intraoperatively and 1 eye postoperatively. Recurrent retinal detachment was observed in 2 eyes postoperatively.? CONCLUSION: According to position of the lens dislocation, personalized surgery strategy is critical for therapy of traumatic lens dislocation. Expulsive choroidal hemorrhage is one of most several complications and should be managed properly.

Objective To evaluate the therapeutic effect of catheter-directed thrombolysis (CDT) for the treatment of acute deep venous thrombosis (DVT) of the lower extremity.Methods Clinical data of 195 patients of acute DVT treated by CDT and adjunctive angioplasty and stenting from August 2010 to February 2014 were analyzed retrospectively.CDT by antegrade puncture of popliteal vein,CDT by great saphenous vein and CDT by retrograde puncture of contralateral femoral vein were used in these cases.Venous recanalization was graded by a thrombus score based on pre-and post-treatment venography.Results Technique success rate,clinical success rate,in popliteal vein group,great saphenous vein group and contralateral femoral vein group were 94.6％,72.2％ and 90.3％,97.3％,83.3％,and 90.0％.Patent rate of deep venous,patent rate of stenting and mild post-thrombotic syndrome (PTS) rate were 88.6％,66.7％ and 75.0％,83.3％,57.1％ and 88.9％,8.3％,26.7％ and 20.8％.Conclusion CDT by antegrade puncture of popliteal vein group combined with adjunctive angioplasty and stenting is safe and effective with higher clinical success rate and better long term results than other approaches for the treatment of DVT patients.

AIM:To evaluate 23G vitrectomy for macular edema in eyes with retinal vein occlusion (RVO) combined with vitreoretinal traction (VMT) or epiretinal membrane (ERM).METHODS:Totally 22 patients (22 eyes) diagnosed with macular edema of RVO combined with VMT or ERM were retrospectively analyzed.Twelve cases performed with 23G vitrectomy together with peeling of inner limiting membrane (ILM) and/or ERM were considered as the observation group or intervention group.Ten cases without vitrectomy were recruited as control group.The best corrected visual acuity (BCVA) and central retinal thickness (CRT) at baseline, 1, 3 and 6mo were recorded and compared.RESULTS:At baseline, the difference of BCVA and CRT between observation group and control group was not statistically significant (P=0.645, 0.206).After vitrectomy, the BCVA and CRT of RVO patients in observation group were significantly improved compared with baseline at each follow-up (F=2.895, P=0.048;F=16.431, P<0.01).However, the BCVA and CRT in control group remained the same as baseline at every follow-up.Moreover, the BCVA and CRT in observation group were much better than that in control group at both 3 and 6mo after vitrectomy.However, the BCVA and CRT between two groups were not significantly different at 1mo postoperatively.CONCLUSION:The 23G vitrectomy could markedly improve BCVA and reduce CRT in RVO patients with macular edema combined with VMT and/or ERM.

After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.
