Correlation between current intensity and effective duration in the treatment of botulinus toxin for cerebral palsy by myoelectricity locating

BACKGROUND： Researches prove that the treatment of cerebral palsy by botulinus toxin （BTX-A） can improve effect and prolong effective duration. Current intensity is the important factor during injection. OBJECTIVE： To observe the changes of motor function and muscular intensity of children with spastic cerebral palsy after injecting BTX-A and analyze correlation between current intensity and effective duration. DESIGN： Cases control trial before and after nerves block SETTING： Capital University of Medical Sciences, China Rehabilitation Research Center PARTICIPANTS： From June 2002 to November 2004, 14 children with spastic cerebral palsy were treated by BTX-A block. All children were hospitalized in the Children Rehabilitation Department of China Rehabilitation Research Center. The children included 9 male and 5 female, and ranged from 4 to 13 years old, and average age was （6±2） years. Muscular tension ranged from grade 1 to grade 3. The diagnosis and the tape of cerebral palsy based on standard of the Fist Nationwide Cerebral Palsy Symposium, and all children were diagnosed with electroencephalogram （EEG）, CT and MRI, and permitted by their guardians. METHODS： （1） Locating and calculation： To locate block points by G6805-2A electro-therapeutic apparatus （Shanghai Huayi Electronic Instrument Plant） at the least stimulating current （continuous wave; impulse frequency; 2.667-83.333 Hz; current intensity： 0-6 mA; voltage： 6 V） to touch off muscles contraction. The current intensity of each point was recorded, and the average current intensity of each patient was calculated at the same time. （2） Dose of BTX-A： Basing upon the spastic degree and weight of patients, the dose was made certain： dose （IU）=（scores of Modified Ashworth Scale ＋2.5） xweight （kg）. The number of the block points was in all 4. The dose of injection ranged from 50 IU to 160 IU with the average of （73.6＋25.8） IU. The BTX-A was made by Lanzhou Institute of Biological Products, and each bottle contains 100 IU BTX-A. Muscular tension was evaluated by Modified Ashworth Scale. The scale ranged from grade 0 to grade 4, and the scores were from 0 to 4. The higher the scores were, the higher the muscular tension was. （3） Effect： Changes of muscular tension were evaluated by modified Ashworth Scale before and after block. Motor function was evaluated by Physician Rating Scale （PRS） before and after treatment. It contained Gait pattern, Hindfoot （ankle） position （stance-floor contact）, Hindfoot position （foot strike）, Knee position （degree of recurvation）, Crouch and Speed of gait. The scores ranged from 0 to 14. The higher the points were, the better the motor function was. （4） Effective duration： The duration was definited by the recovering of the Modified Ashworth Scale. （5） Statistic analysis： Firstly, the current intensity and the effect duration were analyzed by One-Sample Kolmogorov-Smirnov Test, the current intensity： Z= 0.456, P= 0.985, the effective duration： Z= 0.557, P= 0.915. Both data were normal distribution. Secondly, both data were analyzed by Linear Regression. The efficiency of the BTX-A block was analyzed by paired-samples t test. MAIN OUTCOME MEASURES： （1） Changes of motor function of muscular tension; （2） correlation between current intensity and effective duration. RESULTS： Fourteen children with spastic cerebral palsy were all involved in the final analysis. （1） Therapeutic effect： The average score of Ashworth scale after block was lower than that before block [（1.02±0.34） points vs. （2.12±0.48） points, t= 3.644, P〈 0.01]. The average score of RPS after block was higherthan that before block [（9.75±2.78） points vs. （6.16±0.58） points, t =13.222, P〈 0.01]. （2） Relation between the current intensity and the effective duration： The current intensity was （0.1857±0.0506） mA, and the effective duration was （26.36±4.48） weeks. The current intensity was negative correlation with effective duration （r = -0.775, P = 0.01 ）. CONCLUSION： （1） BTX-A occlusion can decrease muscular tension and improve motor function of lower limbs of children with spastic cerebral palsy. （2） The lower the current intensity is, the longer the effective duration is.

Effect of intensive multifactorial treatment on the intima-media thickness of large arteries in patients with new-onset type 2 diabetes mellitus

Objective: To quantify the changes in blood glucose, blood lipids, blood pressure, and the intima-media thickness (IMT) of large arteries in patients with new-onset type 2 diabetes mellitus who received either intensive multifactorial treatment or conventional treatment. Methods: Two-hundred and ten patients with new-onset type 2 diabetes mellitus were randomly assigned to two groups: an intensive treatment group (n=110) and a conventional treatment group (n=100). Fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c), blood pressure, blood lipids [total cholesterol (TC), triglyceride (TG), low-density lipoprotein C (LDL-C), and high-density lipoprotein C (HDL-C)], and IMTs of large arteries (carotid, iliac, and femoral arteries) were determined before and at one and two years after starting treatment. The patients in the conventional treatment group received routine diabetes management in our outpatient department. Targets were established for patients in the intensive treatment group. Their blood glucose, blood lipids, and blood pressure levels were regularly monitored and therapeutic regimens were adjusted for those whose measurements did not meet the target values until all the parameters met the established targets. Within-group and between-group differences were evaluated. Results: A significantly greater percentage of patients in the intensive treatment group had LDL-C levels that reached the target value one year after starting treatment than those in the conventional treatment group (52.04% vs. 33.33%, P<0.05). No significant differences were found be- tween groups for FBG, HbA1c, blood pressure, TG, TC, or HDL-C. The percentages of patients with TG (51.02% vs. 34.48%), TC (52.04% vs. 33.33%), and LDL-C (61.22% vs. 43.67%) who met the respective target values in the in- tensive treatment group were all significantly higher than the corresponding percentages in the conventional treatment group two years after starting treatment (P<0.05). There were no significant differences in the percentages of patients with FBG, HbA1c, and blood pressure values meeting the respective targets between the groups at the two-year follow- up. One year after starting treatment, the LDL-C level, diastolic blood pressure (DBP), and the IMTs of the femoral and iliac arteries of the intensive treatment group were significantly lower compared to those of the conventional treatment group (P<0.05), although there was no significant difference in other metabolic parameters. Two years after starting treatment, the TC, LDL-C, blood pressure [systolic blood pressure (SBP) and DBP], and the IMTs of the carotid and femoral arteries of the intensive treatment group were significantly lower than those of the conventional treatment group (P<0.05). No significant differences in other metabolic parameters existed between the two groups two years after starting treatment. Conclusions: Early comprehensive and intensive treatment of type 2 diabetes mellitus can delay or even reverse the increase in IMT of large arteries. Lowering blood pressure and blood lipid regulation in patients with type 2 diabetes mellitus have great significance in decreasing the risk of diabetes-related macrovascular lesions.

Efficacy and significance of various scores for pneumonia severity in the management of patients with community-acquired pneumonia in China

Background Community-acquired pneumonia （CAP） remains one of the leading causes ot death from infectious diseases around the world.Most severe CAP patients are admitted to the intensive care unit （ICU）,and receive intense treatment.The present study aimed to evaluate the role of the pneumonia severity index （PSI）,CURB-65,and sepsis score in the management of hospitalized CAP patients and explore the effect of ICU treatment on prognosis of severe cases.Methods A total of 675 CAP patients hospitalized in the Second Affiliated Hospital of Zhejiang University School of Medicine were retrospectively investigated.The ability of different pneumonia severity scores to predict mortality was compared for effectiveness,while the risk factors associated with 30-day mortality rates and hospital length of stay （LOS） were evaluated.The effect of ICU treatment on the outcomes of severe CAP patients was also investigated.Results All three scoring systems revealed that the mortality associated with the low-risk or intermediate-risk group was significantly lower than with the high-risk group.As the risk level increased,the frequency of ICU admission rose in tandem and LOS in the hospital was prolonged.The areas under the receiver operating characteristic curve in the prediction of mortality were 0.94,0.91 and 0.89 for the PSI,CURB-65 and sepsis score,respectively.Compared with the corresponding control groups,the mortality was markedly increased in patients with a history of smoking,prior admission to ICU,respiratory failure,or co-morbidity of heart disease.The differences were also identified in LOS between control groups and patients with ICU treatment,heart,or cerebrovascular disease.Logistic regression analysis showed that age over 65 years,a history of smoking,and respiratory failure were closely related to mortality in the overall CAP cohort,whereas age,ICU admission,respiratory failure,and LOS at home between disease attack and hospital admission were identified as independent risk factors for mortality in the high-risk CAP sub-group.The 30-day mortality of patients who underwent ICU treatment on admission was also higher than for non-ICU treatment,but much lower than for those patients who took ICU treatment subsequent to the failure of non-ICU treatment.Conclusions Each severity score system,CURB-65,sepsis severity score and especially PSI,was capable of effectively predicting CAP mortality.Delayed ICU admission was related to higher mortality rates in severe CAP patients.
