Objective To evaluate our noval rod-screw construct in anterior single-segmental decompression and fixation for the treatment of Denis type B burst fractures.Methods From February 2007 through May 2010,we treated 28 patients with Denis type B burst fracture.They were aged from 18 to 52 years (average,37.4 years).The fractures were located at T1 1 in 3 cases,at T12 in 10,L1 in 12,and L2 in 3.Of them,7 were complicated with unilateral pedicle fracture and 3 with bilateral pedicle fractures.According to the American Spinal Injury Association (ASIA) scale,the neurological deficits were rated as grade B in 11 cases,as grade C in 9,and grade B in 8.All the patients received anterior single-segmental decompression,titanium mesh and autogenous bone graft,and fixation with our noval rod-screw construct.The therapeutic efficacy was evaluated in terms of visual analogue scale (VAS),cobb angle,and spinal canal encroachment.Results The mean follow-up time was 26 months (range,from 17 to 33 months).The average length of surgery was 144 minutes(range,from 90 to 176 min);the mean blood loss was 580 mL (range,from 300 to 1 100 mL).The mean VAS score,cobb angle and spinal canal encroachment were improved from 8.2 ± 1.5,17.4° ± 4.3° and 53％ ± 16％ preoperatively to 2.7 ± 2.4,9.4° ± 5.8° and 4％ ±2％ at the final follow-up,respectively(P ＜ 0.05).None of the patients exhibited neurological deterioration.Conclusion Our noval rod-screw construct is a safe and effective device that can be used in the anterior single-segmental decompression and fixation for the treatment of Denis type B burst fractures.

AIM: To investigate effects of salvia miltiorrhiza injection on acute myocardial ischemia and hemorheology. METHODS: The acute myocardial ischemia model and blood stasis model were established with high dose adrenaline subcutaneous injection and being socked in ice water. The effect of salvia miltiorrhiza injection on the electrocardiogram J point and T ware of acute myocardial ischemia and the hemorheology of rat blood stasis model were observed. RESULTS: As compared with model groups, middle and high dose groups of salvia miltiorrhiza injection could obviously inhibit the rising of J point and T wave of the ischemic electrocardiogram, all dose groups of salvia miltiorrhiza injection could prevent the ascending of blood viscosity and fibrinogen and hematocrit. CONCLUSION: salvia miltiorrhiza injection can effectively decrease blood viscosity and improve circulatation of coronary artery, and protect ischemic myocardium.

Objective To explore CT and HRCT manifestations of Swyer-James syndrome(SJS).Methods CT and HRCT were performed in 19 patients,3 of them underwent inspiratory and expiratory HRCT,1 patient surgically proved with bronchiolitis obliterans and bronchiectasis.Results CT demonstrated 37 lobes were involved appearing as hyperlucent and with decreased vascularity ,the volume of lobes decreased in 35(95%) ; CT showed 19 patients with brochiectasis , 2 patients with pulmonary tuberculosis , 6 patients with brochiolitis , and 3 with segmental atelectasis.Conclusion CT and HRCT are very useful for the diagnosis of SJS.

OBJECTIVE:To provide reference for the establishment of clinical skills evaluation system in students majored in clinical pharmacy and pharmacy of China. METHODS:Retrieved from pharmacy OSCE literatures and the related websites,phar-macy OSCE contents and evaluation in the United States,the United Kingdom,Canada,Japan,Malaysia and other countries were introduced to provide suggestions for clinical skills evaluation system in students majored in clinical pharmacy and pharmacy of Chi-na. RESULTS & CONCLUSIONS:OSCE had widely applied in medicine,nursing and other professional clinical skills,the United States,the United Kingdom and other countries had applied OSCE into pharmacy,and confirmed its important role in assessment of clinical competence in pharmacy students. There was no uniform standard in OSCE,and OSCE examinations were slightly different in different countries and different schools. Pharmacy OSCE usually based on school courses such as pharmacotherapy,clinical pharmacokinetics,medicine information,pharmaceutical care,doctor-patient communication,identification and solving ability of clinical drug-related issues. Numerous college of pharmacy in domestic colleges and universities has added the practice-based cours-es,but evaluation system and assessment methods are poor. Almost no OSCE is applied for the assessment of pharmacy students. OSCE has short application time in pharmacy education and relatively less study,therefore,pharmacy OSCE in foreign countries should be learnt to assess clinical skills of pharmacy students,establish and improve the pharmacy OSCE that is suitable for China by combining with the pharmacy education status.

A plasmids of continuous expressing shRNAs targeting the NDV NA-1 Phosphoprotein (P) gene was designed.Virus titration,Real Time RT-PCR,CPE indicated that P-specific siRNA could inhibit virus replication at 36 h post-virus infection.In future studies,a combination of siRNAs targeting the NP and L gene may be used as a tool to study NDV replication and antiviral therapy.

Objective To investigate the diagnostic value of MRI in chronic completely tear of the anterior cruciate lig-ament(ACL). Methods From January 2013 to September 2015 in our hospital,the clinic and MRI data of 20 cases with chronic completely tear of the ACL proved by arthroscopy. Results The diagnostic accuracy rate of MRI was 75%(15/20), and 25%(5/20) was misdiagnosed as partial tear.The MRI signs were: ACL ligament direction (n=20, 100%), abnormal ACL increased signal (14 cases, 70%), tibia forward (n=19, 95%), abnormal deeper lateral femoral notch or bone contusion or cartilage erosion(n=20, 100%), smaller bending angle index of posterior cruciate ligament(n=20, 100%), with the medial meniscus injury(n=18, 90%). MRI also clearly showed other lesions in the knee joint. Conclu-sion MRI has high diagnostic accuracy in chronic completely tear of the ACL, so which is worthy of application.

To optimize the configuration of the conventional SE and FSE sequence parameters in low field MRI. With the combination of larger vision, relatively thinner slice thickness, small number of excitation (NEX = 1 or 2), the signal-to-noise ration and the spatial resolution on follow-up images are moderate, the scan time is significantly shorter along with fewer motion artifacts, the check success rate is improved.

Objective To explore the application value of multislice spiral CT in typical renal angiomyolipoma. Methods A retrospective analysis of clinical and imaging data of 24 patients with classic type renal angiomyolipoma diagnosed by CT. Results Of all the 24 patients,5 patients were male,19 patients were female. Single lesion in 19 cases, multi-ple lesions within the single kidney in 2 cases, each kidney had a lesion in 1 case, multiple lesions in the both kid-neys in 2 cases. The numbers in the multiple lesions5~13. The lesions were round,oval or irregular in shape, 14 le-sions in 8 cases were protruding from the renal capsule outline, the residual lesions were located in the renal parenchyma.Size0.4 cmí0.3 cm~6.7 cmí5.9 cm. Unenhanced CT showed the lesions were rich in fat(CT value-106 HU~-10 HU),and more with streaks and soft tissue density. 3 cases underwent enhanced CT,which showed heteroge-neous enhancemen in the substantive component of the lesions. Conclusion CT is easy to demonstrate gross fat within the angiomyolipoma,and can be used for regular imaging follow-up and preoperative evaluation.

Objective To investigate the MRI findings of displaced bucket-handle tear in medial meniscus. Methods From April 2011 to August 2015 in our hospital, the clinic and MRI data of 12 patients with displaced bucket-handle tear in medial meniscus confirmed by arthroscopy were retrospectively analyzed. Results 12 cases were unilateral. Fragment shift sign, double posterior cruciate ligament sign, flipped meniscus sign and double meniscus forefoot sign, abnormal circumferential meniscus sign, bow tie broken sign and disproportional posterior horn sign could be seen in all cases. Conclusion Displaced bucket-handle tear in medial meniscus has some characteristic manifestations on MRI, MRI can be used as a preferred imaging methods for displaced bucket-handle tear in medial meniscus.
