ObjectiveTo assess the value of comfortable and maximum walking speed of outcome measuring for locomotion recovery after stroke.Methods10m walking speed of 32 stroke subjects who were able to walk independently were tested in the freely chosen and maximum. The motor function of the paretic lower limb and balance were evaluated with the Fugl-Meyer Assessment,Berg Balance Scale and ambulatory item of Functional Independence Measure. The level of association between gait speeds and the clinical variables were examined with Pearson's correlation coefficients.ResultsComfortable walking speed were significantly positively related to maximum walking speed(r=0.953,P<0.001),and balance, motor function of the lower limb and ambulatory function were significantly positively related to comfortable and maximum walking speed(r=0.742-0.834,P<0.001).The relationship between comfortable walking speed and clinical variables was higher(r=0.787-0.834,P<0.001).Conclusions Both comfortable and maximum walking speed can reflect locomotion recovery after stroke, but comfortable walking speed is more pragmatic,securer and more sensitive.

OBJECTIVETo evaluate the effect of length of tibial stump on proprioceptive recovery after anterior cruciate ligament (ACL) reconstruction.
METHODSFrom March 2011 to December 2011,42 patients with ACL tear were performed with reconstruction. The patients were divided randomly into three groups: group A, the patients with remained length of tibial stump ranging from 15 to 20 mm, including 8 males and 6 females, with an average age of (28.2 ± 6.6) years old; group B, the patients with remained length of tibial stump ranging from 5 to 10 mm, including 9 males and 5 females, with an average age of (27.9 ± 6.4) years old; group C, the patients with remained length of tibial stump less than 2 mm, including 9 males and 5 females, with an average age of (28.6 ± 6.8) years, old. The stability of knee were assessed by Lanchman test and anterior drawer test. The function of knee was assessed by Lysholm score and Tegner activity rating. The proprioceptive recovery was evaluated by assessing the passive reproduction of the angles with limb movement into flexion and extension in no weight bearing position.
RESULTSLanchman test and anterior drawer test of all patients were negative at 6 months postoperatively., and there was one case of positive outcome in each group at 12 month and 18 month postoperatively. Lysholm score and Tegner activity score of all patients at 18 month postoperatively were significantly better than that preoperatively, and there were no significant difference among three groups at 18 month postoperatively. There were no significant difference in the production of the angles at flexion to 20° and extention to 80° and 20° among these groups before and after operation. The reproduction of the angles of group A and B at flexion to 50° and extention to 50° at 6 month postoperatively were significantly better than that of group A and B preoperatively and that of group C at 6 month postoperatively, and there were no significant difference among three groups at 18 month postoperatively. The reproduction of the angles of group A and B at flexion to 80° at 12 month postoperatively were significantly better than that of group A and B preoperatively and that of group C at 12 month postoperatively, and there were no significant difference among three groups at 18 month postoperatively.
CONCLUSIONPreservation of tibial stump in ACL reconstruction has benefit in proprioceptive recovery at early stage postoperatively and the length of tibial stump should be reserved with a range from 5 to 10 mm.

The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

Objective:To study the expression of coxsackievirus group B3 gene fragment encoding VP1 in procaryon and to explore its application.Methods:Stablie expression of VP1 gene of CVB3 in E.coli was obtained.The expressed protein was purified by NAT chromatography and its immunoactivity was identified by indirect ELISA.Results:The expressed product of VP1,similar to native protein antigen of CVB3,could strong bind with the mouse's antibody serum against CVB3(polyclonal antibody).Irrelevant monoclonal antibody as contrast presents negative activity. Using the expressed VP1 product,we have had a special IgM ELISA for the patient's serum of the clinical acute viral myocarditis.The result was same with the cellular protein antigens of the tissue-cultivated CVB3.Conclusion:The protein antigen CVB3-VP1 which is obtained by the method of gene engineering has character of high product, and its immunoactivity after being purified was basically unchanged. At present, this kind of antigen is difficult to be obtained from the viral cullture medium and a potent hazard for being infected by this virus may take place in such manipulateion. By the method of gene engineering we can obtain antigenic VP1 of CVB3 and use as immuneogen for the detection of serum antibody,by which to provide reliable test reference for the early-stage diagnosis and clinical therapy of the acute myocarditis.

ObjectiveTo identify the value of walking speed at the evaluation of motor function recovery in hemiparetic patients after stroke.MethodsFifty-five cases were assessed in the study. The walking speed, motor function, strengths of the paretic lower limb,balance and ambulation of ADL function were evaluated with the 10m Maximum Walking Speed Test,Fugl-Meyer Assessment, Motricity Index, Berg Balance Scale and ambulation item of Functional Independence Measure. The level of association between walking speed and the clinical variables were examined with Pearson's correlation coefficients.ResultsIn the slow group, the gait-related clinical scores were related to walking speed (Pearson's r=0.581-0.770,P<0.05),while that in the moderate group and fast group were not (Pearson's r=0.016-0.380,P>0.05).The correlation between the gait-related clinical scores and walking speed was weakened when walking speed above 44.8m/min(or 41.3% of normal values).ConclusionWalking speed plays an independent role as an indicator of improved performance.
