The treatment of cerebral palsy is still a big medical problem.The pathogenesis of spasticity,as result of a variety of lesions of the cerebral cortex,brain stem,spinal cord,is caused by involvement of the inhibitory pyramidal and parapyramidal descending tracts terminating on the spinal facilitatory myotatic reflex.A lesion of the descending tracts disturbs this equilibrium leading to spasticity,which is cha-racterized by muscle resistance at rest that is velocity dependent and associated with an increase in tonic stretch reflexes resulting from hype-rexcitability of the stretch reflex.Spasticity caused abnomal posture,caused special movement,and higher multilation,which affect children's life severely.There are so many ways to lower hypermyotonia,such as:drugs,rehabilitation care,acupuncture and so on.Bioelectric stimulation therapy is a new ways in the zone.Its curative effect and the mechanism are still in explore,this article just to give an overview about bioelectric stimulation therapy in curing spastic cerebral palsy.

BACKGROUND: Plasminogen activator inhibitor 1 is the main regulator of the fibrinolytic system in vivo. The increase of plasminogen activator inhibitor 1 is closely related to thrombotic disease and it is also an independent risk factor for development of thrombotic disease.OBJECTIVE: To investigate the effect of huangqi(Astragalus), danggui (Angelica) and ligustrazine as medicines activating blood and eliminating stasis on the expression of plasminogen activator inhibitor 1 in HepG2 hepatocarcinoma cell strain.DESIGN: A randomized controlled study.SETTING: First Cadre Department of General Hospital of Chinese People' s Armed Police Force.MATERIALS: The experiment was completed in Academy of Military Medical Sciences of PLA from August to December 2004. HepG2 hepatocarcinoma cell strain was cultured. According to different drugs in culture medium, they were divided into six groups: control group, huangqi group,danggui group, huangqi + danggui group, compound danshen group and ligustrazine group.METHODS: Huangqi, danggui, huangqi + danggui, compound danshen and ligustrazine were added in HepG2 culture medium respectively. MTS assay was used to detect the effect of medicines activating blood and eliminating stasis on proliferation of HepG2 cells, plasminogen activator inhibitor 1 was assayed by specific enzyme-linked immunosorbent assays(ELISA),plasminogen activator inhibitor 1 activity was measured by amidolytical assay. 0.5 μg/mL of transforming growth factor β1 cells was added in HepG2 culture medium to stimulated production of plasminogen activator inhibitor 1. Control group was treated under the same conditions but without Chinese herbs.RESULTS: The inhibitory rates of cellular proliferation in huangqi and danggui groups werc(6.51 ±2. 66)% and (4.42 ±2. 19)%, but those in huangqi + danggui, compound danshen and ligustrazine groups were (12. 06 ±4. 98)%, (16. 38 ±4.06)% and(32. 83 ±9.8)% respectively,t = 2. 447 - 3. 707, P ＜ 0.05. Compared with the control group, huangqi,danggui, compound danshen and ligustrazine significantly inhibited plasminogen activator inhibitor 1 expression(22.68 ± 2.20, 11.11 ± 1.23,19.66±1.53, 15.45±1.27, 16.90±0.33, 14.01±0.74, t=2.447-3.707, P ＜ 0.05) and activity(2.16±0.014, 2.01 ±0.006, 1.95±0.014, 1.79±0. 104, 1.53±0.045, 1.48±0.012, t =2.447-3. 707,P ＜ 0.05) in HepG2 cells. The evident inhibitory effects were observed in the group of huangqi + danggui, especially in compound danshen and ligustrazine.CONCLUSION: The plasminogen activator inhibitor 1 expression and activity were inhibited effectively by huangqi, danggui, compound danshen and ligustrazine.

Objective To evaluate the efficacy and safety of colistimethate sodium (CMS) for the treatment of critical patients infected by pan-drug resistantAcinetobacter baumannii (PDR-AB) or pan-drug resistant Pseudomonas aeruginosa (PDR-PA).Methods 321 isolates of PDR-AB and 204 isolates of PDR-PA from critical patients admitted to 35 intensive care units (ICUs) of grade two or above were collected from the Anhui Antimicrobial Resistance Investigation Net (AHARIN) program from September 2012 to September 2015, while the minimal inhibitory concentrations (MIC) of colistin were determined by the E-test. A series of Monte Carlo simulations was performed for CMS regimens (1 MU q8h, 2 MU q8h, and 3 MU q8h, and MU meant a million of unit), and the probability of achieving a 24-hour area under the drug concentration time curve (AUC24)/MIC ratio > 60 and risk of nephrotoxicity for each dosing regimen was calculated. Each simulation was run over three CLCr ranges: < 60, ≥ 60-90, ≥ 90-120 mL/min. The probability of target attainment (PTA)for the AUC24/MIC ratio was calculated using the partial MIC value, while the cumulative fraction of response (CFR) was determined by integrating each PTA with the MIC distributions, the value greater than or equal to 90% or more than 80% was set as the optimal dosing regimen or suboptimal dosing regimen respectively. The probability of average 24-hour serum concentrations up to 4 mg/L for three dosage regimens was used to predict the risks of nephrotoxicity.Results All 321 isolates of PDR-AB and 204 isolates of PDR-PA were susceptible to colistin, the MIC50/90 against PDR-AB were 0.5mg/L and 1.0 mg/L, and those against PDR-PA were 0.5 mg/L and 1.5 mg/L, respectively. When recommended dose (1 MU q8h) was used for patients with CLCr of < 60 mL/min, high CFR value (89.78% for PDR-AB, 81.06% for PDR-PA) were obtained, but with a high risks of nephrotoxicity (> 32.51%). Moreover, low value of PTA (< 66.56%) was yielded for isolates with MIC of ≥ 1 mg/L. Recommended dose also yielded a low CFR value (56.97%-69.31% for PDR-AB, 44.76%-56.94% for PDR-PA) in patients with CLCr of ≥ 60-120 mL/min. When dose was increased to 2 MU q8h, CFR (77.45%-92.87%) and the risks of nephrotoxicity (< 0.15%) was optimal for patients with CLCr ≥ 60-120 mL/min, but low value of PTA (< 75.36%) was also yielded for isolates with MIC of ≥ 1 mg/L. The most aggressive dose of 3 MU q8h provided high CFR (> 89.24%) even in patients with CLCr ≥ 90-120 mL/min, and PTA was < 76.20% only for isolates with MIC of ≥ 1.5 mg/L, but this dosing scheme was associated with unacceptable risks of nephrotoxicity (> 33.68%).Conclusion Measurement of MIC, individualized CMS therapy and therapeutic drug-level monitoring should be considered to achieve the optimal drug exposure and ensure the safety of CMS.
