Objective To investigate the diagnostic points of multiple sclerosis and multiple metastatic encephaloma.Methods Choose a case of multiple sclerosis,which had been misdiagnosed as multiple metastatic encephaloma and operated on,to analyse its reasons of misdiagnosis.Results Reasons for the misdiagnosis:The neglect of the importance of the disease history.The scant knowledge of the early represen- tations of the atypical MS(demyelinating pseudotumor).The lack of the knowledge of the non-demyelinating lesions of the MS.The lack of attention to the different representations of the MRI scan between the acute MS and the multiple metastatic encephaloma.The excessive importance is attached to the imageological report. The neglect of the routine examination of cerebrospinal fluid.Conclusion When multiple metastatic en- cephaloma develops,the differential diagnosis of MS should be made.The further examinations should be done to those cases which are hard to tell the difference with metastatic encephaloma by clinical and imageo- logical representations.Try to avoid undergoing surgery or radiotherapy hastily.

0.05 ).But the difference of positive ratio between 1-year-old group was significant in 6 cases of B19 DNA positive (P0.05).Conclusion There are no markedly association between kawasaki disease and human parvovirus B19 infection.

Based on the quality of students, we reasonably arranged thetraining course content and enhanced the training of clinical skills; and at the same time focused on teacher training of general practitioners to strengthen the training bases, so as to improve the overall construction of teaching effect, to adapt to the actual medical need of the community and improve community medical service level to achieve the purpose of general practitioners training.

Objective The study aimed to compare the vector system with the hand instrument in the pain severity during scaling and root planning.Methods 60 periodontal patients were randomly divided into two groups for supportive periodontal therapy (SPT):the experimental group (using vector system) and the control group (using gracey instruments),with 30 cases in each group.And the painfulness after SPT was evaluated by Visual Analogue Scale (VAS).Results 66％ patients felt mild pain during the supportive periodontal therapy with the application of vector system,while 36％ patients felt mild pain in the control group.24 patients in the experimental group accepted vector system for SPT and 23 patients in the experimental group felt less fear of the treatment.Conclusions Patients will feel less discomfort with the application of the vector system,therefore better compliance will be reached.And the cooperation of the doctors and nurses has great impact on the treatment effect.

Objective To evaluate the effect of dexmedetomidine administered locally on the median effective concentration ( EC50 ) of ropivacaine for paravertebral nerve block ( PVNB) . Methods Forty?eight ASA physical status Ⅰ or Ⅱ female patients, aged 20-64 yr, with body mass index<24 kg∕m2 , scheduled for elective unilateral segmental mastectomy under PVNB, were randomly divided into 2 groups ( n=24 each) using a random number table: ropivacaine group ( group R) and ropivacaine mixed with dexmedetomidine group ( group RD) . PVNB was performed at T4 on the operated side guided by ultrasound and nerve stimulator. Ropivacaine 20 ml and a mixture of ropivacaine and 20 μg dexmedetomidine 20 ml were injected locally in group R and group RD, respectively. The concentration of ropivacaine was determined by up?and?down sequential allocation. The initial ropivacaine concentration was set at 0. 35%, and the ratio between the two successive concentrations was 1. 2. The EC50 and 95%confidence interval of ropivacaine were calculated using Dixon?Massey method. Results The EC50 ( 95%confidence interval) of ropivacaine was 0.27% (0.23%-0.30%) and 0.22% (0.18%-0.25%) in group R and group RD, respectively. Compared with group R, the EC50 of ropivacaine was significantly decreased by 19% in group RD. Conclusion Small dose of dexmedetomidine administered locally can significantly enhance the efficacy of PVNB with ropivacaine.

OBJECTIVETo investigate the clinical efficacy of cannulated screw fixation with percutaneous Poking reduction for the treatment of Sanders II, III calcaneal fracture.

METHODSFrom January 2012 to January 2014, 19 patients with Sanders II, III calcaneal fracture were treated with cannulated screw fixation with percutaneous Poking reduction. There were 14 males and 5 females, ranging in age from 19 to 58 years old, with an average age of (38.3 +/- 4.1) years old. The changes of Bohler angle and Gissane angle were measured and compared preoperatively and postoperatively to observe the recovery of the articular surface. The Maryland Foot Score was used to evaluate operation outcomes.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 28 months with a mean of (22.3 +/- 5.3) months. The Bohler angle and Gissane angle were improved significantly after operation compared with those before operation (P < 0.05). The Maryland score was 83.2 +/- 8.4.

CONCLUSIONTreatment of calcaneal fractures with screw fixation with percutaneous Poking reduction has several advantages such as satisfactory outcome,less damage, fewer complications, quicker recovery, and shorter hospital stay,and it is one of the effective treatments for Sanders II and III calcaneal fractures.
