Objective To observe the effects of obesity on dose-response curve of rocuronium in female patients and calculate ED9 5 of rocuronium.Methods Eighty female patients,aged 18-45 years, falling into ASA grade Ⅰ or Ⅱ,schedualed for elective surgery under general anesthesia,undergoing surgery less than 1.5 h,were included in the study.The patients with body mass index of 20-25 kg/m2 as group N were randomized to divided group N1,group N2,group N3 and group N4.Anoth-er 40 patients with body mass index of 30-35 kg/m2 as group B were randomized to divided group B1, group B2,group B3 and group B4.When the first twitch height of TOF (T1)was 100%,groups N1-N4 and groups B1-B4 patients were injected rocuronium 0.075,0.1,0.1 5,0.3 mg/kg respectively. The first dose of rocuronium in each group,T1 maximum inhibition degree and onset time were re-corded.The relationship between probit-transformed depression of T1 and the logarithm dose of rocu-ronium was analyzed by linear regression.ED50 and ED9 5 of rocuronium in obese and normal body weight patients were calculated.Results Dose-response curve equation of each group were Y1 =3.464X1 -2.23 and Y2 = 3.843X2 - 2.750 respectively(P < 0.05 ).The ED50 and ED9 5 (95% CI)of rocuronium were 0.122 (0.092-0.1 65 )mg/kg and 0.324 (0.242-0.433 )mg/kg in group N,and were 0.103 (0.078-0.133)mg/kg and 0.25 1 (0.1 93-0.326)mg/kg in group B.Conclusion Obesity significantly affects the dose-response curve of young women and can enhance the sensitivity of them to the rocuronium.The ED9 5 of obese patients is 0.25 1 mg/kg.

Objective To compare the effect of the rehabilitation training during or after acupuncture on edema and pain of shoulder-hand syndrome after stroke. Methods 60 patients with shoulder-hand syndrome were divided into two groups. The control group performed the routine rehabilitation training after the acupuncture, while the treatment group during the acupuncture. The pain and edema of the affected hands were observed. Results The pain and edema decreased significantly after treatment compared with that of control(P<0.01). Conclusion The rehabilitation training during acupuncture is more effective on shoulder-hand syndrome than the routine rehabilitation training after acupuncture.

Objective To explore the effect of functional electrical stimulation combined with treadmill training and botulinum toxin type A injection on foot-drop and strephenopodia among stroke survivors.Methods Sixty-seven stroke survivors with foot-drop and strephenopodia were randomly divided into an electrical stimulation group (n=23),a conventional treatment group (n =22) and a combined treatment group (n =22).All 3 groups received a 400 U injection of BTX-A and electrical stimulation.After 24 hours,the patients in the conventional treatment group received conventional treatment including a brain protection agent,limb function exercises,gait training,balance training and training in the activities of daily living.The patients in the combined treatment group received that conventional treatment,plus functional electrical stimulation and weight loss training on a treadmill.The patients in the electrical stimulation group received functional electrical stimulation treatment supplementing the conventional treatment.Therapeutic effects were evaluated before and after six weeks of treatment using integral electromyography (iEMS) of the anterior tibial muscle and the lateral head of the gastrocnemius muscle,the co-contraction ratio (CR) during ankle dorsiflexion,the modified Ashworth Scale (MAS),the Berg balance scale (BBS),a functional walking score (FAC),and the active range of motion (AROM) of the ankle in dorsiflexion and eversion.Results After the treatment,significant improvement was observed in all three groups in the average iEMS value of the anterior tibial muscle and the lateral head of the gastrocnemius muscle,the CR in ankle dorsiflexion,and in their MAS,BBS,FAC and AROM results.There was no significant difference among the three groups after treatment in their average iEMS values at the lateral head of the gastrocnemius.The average values of the other indicators were,however,significantly better in the combined treatment group than in the other 2 groups.Conclusion Functional electrical stimulation combined with treadmill training and botulinum toxin type A injection can significantly improve foot-drop,strephenopodia and the walking function of stroke survivors.This combined treatment deserves popularization and application in clinical practice.
