Objective To observe the effect of functional exercise guided by self muscle strength in early rehabilitation on patients after total knee arthroplasty (TKA). Methods From September, 2014 to September, 2015, 62 patients after TKA were randomly divided into ex-perimental group (n=31) and control group (n=31). The control group received conventional rehabilitation training, while the experimental group received rehabilitation training under the guidance of their own muscle strength standard. The degrees of swelling and pain seven days after TKA; the muscle strength seven and 15 days after TKA; the range of motion (ROM), the Keen Society Score (KSS) 15 days after TKA;and the postoperative hospital stay were compared. Results There was no significant difference in all the indexes above between two groups before TKA (t<0.960, P>0.05), and all of them improved after TKA (t>3.470, P<0.01). There was no significant difference in the de-grees of swelling (t=1.800, P=0.077) and pain (t=0.840, P=0.404) seven days after TKA. The score of quadriceps strength was higher in the experiment group than in the control group (t>2.280, P<0.05) seven and 15 days after TKA. There was no significant difference in the ROM of the knee and the score of knee between two groups (t>0.850, P>0.05), and the functional score was higher in the experiment group than in the control group (t=5.870, P<0.001) 15 days after TKA. The postoperative hospital stay was shorter in the experiment group (t=7.65, P<0.01). Conclusion Functional exercise under the guidance of their own muscle strength standard could contribute to the improvement of postoperative muscle strength and knee joint function, and shorten the hospitalization stay.

Objective By taking emergency treatment of craniocerebral trauma for example, we studied the competence characteristic composition for emergency treatment of eraniocerebral trauma aiming at doctors and nurses, besides,their competence characteristics were compared as well. Methods By comprehensive application of qualitative and quantitative methods, the competence characteristic eomposi-tions of doctors and nurses were obtained, the corresponding competence characteristic scale was estab-lished, and underwent subsequent application for its validity and reliability. Results After many times of factor analysis and factor rotation, competence characteristic compositions and scale for doctors and nurses engaged in emergency treatment of eraniocerebral trauma were obtained, accumulative contribution of com- mon factors was 69.33% and 69.99%,ot coefficient was 0.826 and 0.930, split-half reliability was 0.771 and 0.791 ,α coefficient of internal consistency of every subseale ranged from 0.574 to 0.898, which showed good validity and reliability. Conclusions Doctors and nurses engaged in emergency treatment of cranio-cerebral trauma possess different competence characteristic compositions from general medical workers,their competence characteristics are both overlapping and different.

Objective To observe the effect of omeprazole or famotidine combined with itopride in the treatment of reflux esophagitis.Methods 86 patients with reflux esophagitis were randomly divided into two groups,which group A with 43 eases was treated with omeprazole combined with itopride,and group B with 43 cases was treated with famotidine combined with itopride.The clinical effect and main symptoms were observed and compared.Results The total effective rate in group A was 91.3％,significantly higher than that of group B ( 71.4％ ) ( x2 =5.460,P ＜0.05 ).After treatment,the scores of heartburn,acid reflux and chest pain were significantly decreased ( all P ＜ 0.05 )in both two groups.Moreover,the scores of heartburn,acid reflux and chest pain in group A after treatment were significantly lower than those of group B ( all P ＜ 0.05 ).Conclusion Omeprazole combined with itopride in the treatment of reflux esophagitis is better than famotidine combined with itopride.
