ObjectiveTo study the method about language rehabilitation for Broca aphasis with bucco-facial apraxia in hemiplebies after stroke.Methods55 patients in hemiplegies after stroke who were diagnoised Broca aphasia with bucco-facial-apraxia by Chinese standard language test of aphasia and apraxia test,were randomly divided into two groups:treatment group(30 cases) and control group(25 cases). The trainning about language rehabilitation and occupational therapy(OT)to bucco-facial-apraxia were given in the treatment group, while in the control group the language rehabilitation training were given only. Evaluation was done in pre-treatment and post-treatment respectively.ResultsThe improvement of bucco-facial-apraxia and language expression function(repetition,speech and speech-reading) of treatment group were significant than that of control group (P<0.05).Conclusions The OT for bucco-facial-apraxia may obviously improved bucco-facial-apraxia and language expression function on training of language rehabilitation for Broca aphasia with bucco-facial-apraxia.

To investigate the relationship between diabetic macular edema (DME) and serum E-selectin level.
●METHODS: Totally 90 patients with diabetic retinopathy in our hospital from October 2009 to October 2013 were observed. Retrospective analysis of the correlation between macular edema degree and serum soluble E -selectin ( sE - sel ). Ninety patients with diabetic retinopathy were divided into two groups: DME group and non - DME group. The level of sE - sel and microalbuminuria (MA) of two groups were determined and compared.
●RESULTS: There was significant difference in MA, sE-sel levels of groups ( P < 0. 05). The value of diabetic retinopathy patients with sE - sel and MA, FBG were positively correlated ( r = 0. 728, P < 0. 05; r = 0. 651, P <0. 05).
●CONCLUSlON: Elevated levels of sE-sel is a risk factor for diabetic macular edema, and sE-sel was involved in the pathogenesis of diabetic microangiopathy.

Objective To explore the operation timing and technique selection of floating knee injury in children.Methods According to Letts types,36 cases were divided into 5 types.The function outcome in every group was compared by Karlstrorm criterion according operation timing or technique selection respectively.Results Thirty-six cases were followed up for an average of 25 months(19 to 84 months).The rate of excellent and good results accounted for 94.12%(16/17) in one stage operation,78.95%(15/19)in stages,60%(6/10)in 2 stages,respectively.Conclusions It may be recommended to treat children with floating knee injury with open reduction intenal fixation or external fixation.The best operation time shall be urgent treatment of both femur and tibia fracture.

·Uveitis is an inflammation of any or all parts of the uveal tract including the iris, ciliary body and the choroid. Despite current advances in diagnosis and management, visual loss occurs in 35%-45% of patients with uveitis. The etiopathogenesis of uveitis remains unknown; it may be associated with environmental and immunogenetic factors. Many studies have demonstrated polymorphisms in major histocompatibility complex (MHC) genes may determine involvement in uveitis. Recently polymor-phisms in non-MHC genes, including cytokine and che-mokine genes, have been reported to play important roles in the pathogenesis of uveitis. This article reviewed the advances in the studies on cytokine and chemokine gene polymorphisms associated with uveitis.

Objective To know automobile exhaust pollution and population exposure to automobile exhaust in Taiyuan,and to provide the basis for controlling automobile exhaust pollution.Methods Two different automobile pollution areas(A and B) were selected as the monitoring sites,the continue sampling was carried out for one week from March to April in 2008.The concentration of PM2.5 was determined by mass method,the inorganic elements in PM2.5 were extracted by Soxhlet method, arsenic and mercury were measured by atomic fluorescent spectrophotometer(AFS),the other metal elements were measured by atomic absorption spectrophotometer.The concentration of NO_x was detected by Saltzman method,the concentration of CO was measured by non-dispersive infrared absorption method.Results At crossroad A,daily average concentration of PM2.5 was 1.604 mg/m~3,which was significantly higher than that at crossroad B(0.64 rag/m~3),P

Objective To assess the application of contrast-enhanced ultrasound (CEUS) in evaluation of the renal cortical and medullary perfusion changes before and after acute renal failure (ARF) in rabbits. Methods Rabbit ARF models were established with intramuscular 50% glycerin (12-15 ml/kg) injection into rabbits' thighs. One day before and after ARF models establishment, CEUS was performed on each rabbit. The renal perfusion time-intensity curve (TIC) was analyzed, including parameters like AT (arrival time), TTP (time to peak intensity), A (amplitude of peak intensity), AUC (area under the curve), β (slope rate of TIC) of renal cortex and medulla. Results The value of A and β before model establishment was (17.36±13.73) dB and (5.38±2.08) dB/s, respectively, both was significantly higher than those after glycerin injection ([6.59±4.25] dB and [1.58±1.41] dB/s, respectively) (P<0.05). The value of TTP and AUC before model establishment was (2.46±1.76) s and (329.31±171.70) dBs, both was significantly lower than those after injection ([5.93±4.80] s and [722.28±354.14] dBs, respectively) (P<0.05). No significant difference was found in AT of renal cortex and AT, A, TTP, AUC, β of renal medulla, nor in SCr or BUN. Conclusion CEUS can display the changes of perfusion image of the renal cortex of the ARF earlier than SCr and BUN.

Objective The aim of this study was to evaluate magnetic resonance cholangiopancreatography(MRCP)using half-Fourier acquisition single-shot fast spin-echo(HASTE)sequence in the diagnosis of biliary obstructions.Methods Forty-five patients with pancreaticobiliary duct diseases underwent MRCP on 1.5 T scanner,a heavily T 2-weighted HASTE was used during a breath-hold.The source images were three-dimensional reconstructed postprocessed on workstation.The findings of MRCP images were analyzed and compared with US,CT,ERCP or PTC.Results The diagnostic accuracy of MRCP was 94%,the same as ERCP(92%),but it was superior to US and CT(?

· AIM: To investigate the efficacy and safety of intravitreal injection of plasmin, hyaluronidase, or the combination of the two in inducing posterior vitreous detachment (PVD).· METHODS: 15 mini-type pigs were assigned to three groups (Group A, B and C), 5 in each group. One eye of each pig was intravitreally injected with the studying agent,and the fellow eye was used as control. Group A received a vitreous injection of hyaluronidase 50U (0.1mL); group B received plasmin 0.5U (0.1mL); group C received plasmin 0.5U (0.05mL) combined with hyaluronidase 50U (0.05mL). The fellow eyes in each group were injected with 0.1mL balanced salt solution (BSS). All the pigs were examined with slit-lamp biomicroscope, direct and indirect ophthalmoscope, B-scan and electroretinograph (ERG). After 7 days, the animals were killed and the eyes were enucleated and examined with light microscope, transmission electron microscope and scanning electron microscope.· RESULTS: B-scan examination showed that one eye of Group A and two eyes of Group B had partial PVD at 1st day after injection and one eye of Group C at 1 hour after injection. On the 7th day, B-scan, light microscopy and scanning electron microscopy demonstrated that all the eyes of Group A and Group B had partial PVD, while none of the control eyes had PVD. Rank sum test for scanning electron microscopy results of all the groups showed P ＜0.005.Furthermore, the comparisons between every two groups were made. The results of analyses were as follows: P＞0.05 between the drug injected eyes of Group A and Group B, P＜0.05 between Group B and Group C, Group A and Group C.The b-wave and a-wave amplitudes of ERG showed no significant difference either between preinjection and postinjection in all groups or between the drug injected eyes and the control eyes in each group. Light microscopy and transmission electron microscopy revealed no damage to the retinal structure.· CONCLUSION: Intravitreal injection of hyaluronidase 50U or plasmin 0.5U or their combination can produce PVD effectively and quickly without retinal functional or structural toxicity. The combination of the two proteases was proved to be synergetic.
