Objective To investigate the relationship between Oxfordshire community stroke project(OCSP) classification and imaging classification in acute cerebral infarction. Methods Two hundred and thirty-six patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification,of all the 236 patients with acute cerebral infarction,28(11.9%) experienced total anterior circulation infarction(TACI),71(30.1%) partial anterior circulation infarction(PACI),94(39.8%) lacunar infarction(LACI),and 43(18.2%) posterior circulation infarction(POCI).The consistency was found in 171 cases(72.5%) between the OCSP classification and imaging classification,with the accuracy of 76%(25/33) for TACI,81%(34/42) for PACI,71%(81/114) for LACI and 66%(31/47) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy,and is well consisted with the imaging findings.

In order to discover some sensitive parameters of eight diastolic function indexes and establish the discriminant equation, twenty-three patients with coronary heart disease (CAD) and eighteen normal adults were studied by radionuclide, Doppler and apexcardiography. The results showed that eight indexes were signicantly different between CAD and normal groups. The discriminant equation was: Z=0.21X1+23.86X2-22.88X3-0.18X4+2.83X5+ 2.06X6+66.86X7+1.66X8. The discriminant score was 42.99. The discriminant function was 100%. The contributive rates of eight indexes were Ev/Av, 1/3FF, A/E-O, PFR, DATI, EDC, IRT ;and l/3FFd from large to small value, respectively. It is concluded that Doppler Ev/Av is the most sensitive diastolic function index of CAD.

Objective To study the accuracy of preoperative planning and postoperative satisfaction of prosthesis posi?tion by applying the personal surgical cutting guide (PSCG) to total knee arthroscopy (TKA) based on 3D printing technique. Meth?ods In this randomized study, 20 patients were selected from August 2014 to October 2015, who were randomly divided into two groups. In PSCG group, 4 males and 6 females were enrolled, with a mean age of 70.9±6.69 (from 59 to 78) years. In con?ventional instrumentation group, 2 males and 8 females were enrolled, with a mean age of 69.9 ± 6.35 (from 58 to 77) years. The conventional instrumentation group was treated with conventional TKA, while the PSCG group was treated with personal surgical cutting guides. Then the knee valgus angle of patients, the angle between prosthesis components on the coronal and the sagittal plane of two groups were evaluated. Subsequently the correlation of the actual osteotomy amount, the valgus angle, caster angle, external rotation angle between intra? and preoperative planning were compared in the PSCG group. Results Compared with the ideal value of each angle, the mean deviation of the hip?knee?ankle angle 0.77°±0.51°, frontal femoral compo?nent angle 0.37° ± 0.53° and frontal tibial component angle 0.11° ± 0.24° showed statistically significant difference between two groups (P<0.05). The mean deviation of the lateral femoral component angle and the lateral tibial component angle (respectively 8.26°±0.85°, 0.71°±0.77°) were smaller than that of the conventional instrumentation group, while the differences all had no statis?tically significant difference (P>0.05). The actual osteotomy amount, the valgus angle, caster angle, external rotation angle corre?lated well between intra?and preoperative planning (t=-2.547, 3.864, 0.537,-0.040,-1.290, P>0.05). Conclusion TKA assist?ed by PSCG can make lower extremity alignment and accuracy of prosthesis implantation more accurate compared with convention?al TKA, especially in hip?knee?ankle angle, frontal femoral component angle and frontal tibial component angle.

Objective To assess the value of thickness and arterial resistive index (RI) of wrist synovium in differentiation from activity to non-activity of rheumatoid arthritis (RA). Methods Ninety-two clinically confirmed RA patients underwent high frequency ultrasonography. Maximum thickness and arterial RI of the wrist synovium were measured in active and nonactive stage. Results Thickened synovium was found in 75 of 92 patients. Color signal in the synovium was detected and then RI was measured in 67 patients, including 31 in active stage and 36 in nonactive stage. The wrist synovium thickness of 67 patients was (2.97±1.49) mm and arterial RI was 0.74±0.17. RI decreased significantly in patients in active stage compared with that in nonactive stage (P<0.001). Conclusion Arterial RI measurement with high frequency ultrasonography may be served as an objective marker of synovial membrane disease in RA. The thickness of synovium cannot predict the activity of RA.
