Objective To investigate the rehabilitation outcome in hemiplegic stroke patients with upper limb dysfunction treated with electromyographic(EMG)biofeedback therapy in combination with an intelligent Tongluo therapeutic apparatus.Methods A total of 132 stroke patients with hemiplegia were chosen and divided into observation group and control group according to the rehabilitation strategies,with 66 cases in each group.Control group was treated with EMG biofeedback therapy,while observation group was given the integrated therapy of EMG biofeedback therapy and intelligent Tongluo therapeutic apparatus.The two groups were compared for motor function of the hemiplegic upper limb(shoulder,hand and wrist muscle),integrated electromyography(iEMG)in the affected limb flexion and extension(biceps brachii and triceps brachii),range of motion of the shoulder joint(abduction,external rotation,internal rotation)and Barthel index of activities of daily living(ADL).Results The differences in the iEMG of biceps brachii and triceps brachii of the elbow joint,motor function of the hemiplegic upper limb,range of motion of the shoulder joint and ADL between two groups before treatment were trivial(P>0.05).The treatment in observation group increased the iEMG of biceps brachii and triceps brachii in elbow flexion(P<0.05),decreased the iEMG of biceps brachii in elbow extension but increased the iEMG of triceps brachii in elbow extension(P<0.05),and these improvements were more significant than those in control group(P<0.05).After treatment,the scores for shoulder function,hand function,and wrist muscle function in observation group increased from(12.23±2.76)to(26.77±4.28),(6.54±1.34)to(15.35±2.46),and(2.36±0.46)to(8.13±2.52),and the scores of the above indexes were higher than those in control group(P<0.05).The shoulder abduction,external rotation and internal rotation ranges of motion in observation group after treatment were greater than those before treatment[(90.77±8.35)° vs(61.23±6.35)°,(45.36±5.33)° vs(26.33±4.65)°,(52.55±5.86)° vs(32.44±3.87)°],and the observation group had greater shoulder ranges of motion than control group(P<0.05).The ADL score in observation group after treatment was higher than that before treatment[(62.45±5.25)vs(33.35±4.85),P<0.05],and it was also higher than that in control group(P<0.05).Conclusion EMG biofeedback therapy combined with intelligent Tongluo therapeutic apparatus can effectively improve the iEMG in the affected limb flexion and extension,enhance the ranges of motion of the shoulder joint,and ultimately improve the upper limb motor function and life quality of hemiplegic stroke patients.

Objective:To establish and validate a predictive model for treatment failure of peritoneal dialysis-related peritonitis(PDAP)in elderly patients.Methods:Clinical data of peritoneal dialysis(PD)patients who were followed up from January 1, 2013 to December 31, 2019 at four Grade A tertiary hospitals in Jilin Province were collected.A total of 362 elderly patients with PDAP were eventually included as study subjects.Subjects recruited from 2013 to 2017 were used for model construction and the logistic regression model was used to screen risk factors for treatment failure of PDAP in elderly patients.A nomogarm was constructed to predict treatment failure of secondary PDAP using R language.The receiver operating curve(ROC)and calibration curve were used to evaluate discrimination accuracy of the model.Subjects from 2018 to 2019 were used as the cohort for validation of discrimination accuracy of the model.Results:Of 258 PDAP patients in the modeling cohort, 29 experienced treatment failure, including 15 PDAP-related deaths and 14 cases requiring catheter removal.The multivariate logistic regression model showed that types of pathogens( OR=8.849, 95% CI: 1.656-47.269, P=0.011), long dialysis age( OR=1.023, 95% CI: 1.005-1.042, P=0.013), pre-hospitalization antibiotic treatment( OR=5.123, 95% CI: 1.338-19.610, P=0.017), and dialysate white blood cell count on day 5>100×10 6/L( OR=7.085, 95% CI: 2.162-23.217, P=0.001)were independent risk factors for treatment failure of PDAP in elderly patients.For the nomogarm predictive model, the areas under the ROC curve(AUC)in the modeling cohort and the validation cohort were 0.818(95% CI: 0.735-0.902)and 0.762(95% CI: 0.656-0.889), respectively, and the calibration curves were close to a straight line with a slope of 1. Conclusions:Our nomogram predictive model based on types of pathogens, months of dialysis, pre-hospital admission antibiotic treatment, and dialysate white blood cell count on day 5 has demonstrated satisfactory discrimination accuracy for treatment failure of PDAP in elderly patients.

Objective To evaluate the multi-spiral CT(MSCT)imaging features and classification of renal pelvis carcinoma.Meth-ods 76 patients of renal pelvis carcinoma proved pathologically were analyzed retrospectively,and divided into different types ac-cording to the MSCT features.The MSCT differences for different types were analyzed.Results Most of the tumors showed iso-density or slight hyperdensity (95%)on un-enhanced images,and persistent mild-to-moderate enhancement (91%)in enhanced im-ages.All cases were divided into three types:pelvic mass type in 30 cases (39%),substance invasion type in 25 cases (33%),wall thickening type in 21 cases (28%).All cases were also divided into two types:substance invasion type(25 cases,33%)and renal pelvis type(5 1 cases,67%).The occurrence rate of local low enhancement,whole kidney low enhancement,hydronephrosis,lymph node metastasis and vein tumor thrombus were 80%,20%,48%,52%,1 6% in substance invasion type cases,and 4%,42%, 75%,4%,6% in the renal pelvis type cases,respectivily.Conclusion MSCT multiphase enhancement scanning shows important valuation in the diagnosis and classification of renal pelvis carcinoma.Obvious differences of CT features are showed for different types.The diagnosis accuracy may be improved by the knowledge of substance invasion type.
