Journal of Acupuncture and Tuina Science 2007;5(1):10-13
Objective: To observe the effects of electro-acupuncture on S-100 protein expression of nerve fibers on the regeneration process of transected sciatic nerve of rats, so as to explore the partial mechanism of electro-acupuncture treatment for peripheral nerve injury.Methods: Following rat's sciatic nerve transection, the nerve regeneration chamber model was established, then the rat was given electro-acupuncture stimulation at the frequency of 5 Hz and frequency of 100 Hz, and the immunohistochemical staining method and image analyzing semi-quantitative technique were adopted to determine the percentage of S-100 protein area,hence to observethe effect of electro-acupuncture on the repair process of transected sciatic nerve of rat and the S-100 protein expression. Results: Electro-acupuncture could significantly potentiate the S-100 protein expression of Schwann Cells (SC) in the repair process of transected sciatic nerve. At the 14th week, 17th week and 20th week after operation, the percentages of S-100 protein area were more obviously increased in 5 Hz electro-acupuncture group and 100 Hz electro-acupuncture group than in model group, with significant differences (P<0.05). Especially, the better effect was obtained in 5 Hz electro-acupuncture group. Judging from the dynamic treatment, it is very vital to be treated early. Conclusion: Electro-acupuncture is an effective method for the treatment of peripheral nerve injury, and its therapeutic effect is related to the improvement of SC proliferation.

Objective To explore the relationship between left atrial diameters (LAD) and prothrombotic state in senile patients with hypertension (HT) and atrial fibrillation (AF). Mcthods Totally 105 patients with cssential hypertension were divided into 65 patients with atrial fibrillation and 40 cases without atrial fibrillation,and then patients with atrial fibrillation were subgrouped into paroxysmal and persistent atrial fibrillation groups.30 healthy people without hypertension and atrial fibrillation were used as control group.LAD was determined by M type ultrasound cardiogram.Fibrinogen (Fg),D-Dimer(D-Dimer),von willebrand (vwF) and haematocrit (HCT) were also measured as prothrombotic state and compared among the groups. Results In groups of HT with AF versus HT without AF versus control,LAD[(43.56 ± 6.72) mm vs.(36.28 ± 5.83) mm vs.(31.63±4.32)mm],Fg[(4.24±0.59)g/L vs.(3.09 ±0.49)g/L vs.(2.80± 0.46)g/L],D-Dimer [(0.43±0.13)mg/L vs.(0.28±0.]0)mg/L vs.(0.18±0.08)mg/L],vwF[(290.44±29.02)% vs.(101.32±21.36)% vs.(84.15±20.26) %],HCT[(0.46±±0.07)vs.(0.37±0.05)vs.(0.34±0.03)]were significantly higher in HT patients with atrial fibrillation than those without atrial fibrillation and control ( all P< 0.05),and there were differences in LAD and D-Dimet (P<<0.05),but not in Fg,vwF and HCT (all P>0.05) between patients without atrial fibrillation and control.LAD[(46.75±7.32)mm vs.(40.82±6.21)mm],Fg [(4.68±0.65)g/L vs.(3.85±0.53)g/L],D-Dimer [(0.48±0.16)mg/L vs.(0.40±0.12)mg/L],vwF [(384.96±29.75)% vs.(209.43±28.63)%] and HCT [(0.49±0.08)vs.(0.43±0.06)] in persistent atrial fibrillation group were increased than those in paroxysmal atrial fibrillation group ( P < 0.05 ).Fg ( r =0.683 ),D-Dimer ( r =0.735 ),vwF ( r=0.763) and HCT(r=0.759)were corrclated with LAD (all P<0.01). Conclusions Increased LADmight he one of the elevated risks of atrial fibrillation and a higher prothrombotic state is increasing with larger LAD in senile hypertension.

Objective To analyze the risk factors associated with acute renal failure (ARF) in critically ill obstetric patients in intensive care unit (ICU).Methods A retrospective analysis of 192 critically ill obstetric patients admitted to the ICU for postpartum complications was conducted. There were 10 patients excluded because 3 died of amniotic embolism with massive hemorrhage in ICU and 7 had incomplete records, therefore, only 182 critically ill obstetric patients were enrolled in this study. According to the occurrence of ARF or not, the patients were divided into ARF group (68 cases) and non-ARF group (114 cases). The indicators of preeclampsia, HELLP syndrome (hemolysis, elevated liver enzymes, thrombocytopenia), acute fatty pregnancy liver, postpartum hemorrhage, sepsis were collected in the two groups. The main drugs used in the 4 days after delivery were as follows: ① plasma volume expanders: fluids (crystalloids, artificial colloids, hypertonic albumin and 4% serum albumin) and blood products (packed red cells, concentrated platelets, fibrinogen, fresh frozen plasma and activated factor Ⅶ); ② antifibrinolytic drug: tranexamic acid; ③ anti-hypertensive drugs: angiotensin-converting enzyme inhibitors (ACEI), diuretics; ④ nephrotoxic drugs: aminoglycosides, contrast agent. The above indexes were firstly analyzed by the univariate method, and the risk factors with statistical significance were further analyzed by multivariate logistic regression method to screen out the independent risk factors of developing ARF in critically ill obstetric patients in ICU.Results Univariate analysis showed that HELLP syndrome, tranexamic acid and hypertonic albumin infusion used in 4 days after delivery were the risk factors of ARF (χ2 value was 4.92, 4.29, 5.53, respectively, allP < 0.05). The multivariate logistic regression analysis showed: HELLP syndrome [odds ratio (OR) = 10.478, 95% confidence interval (95%CI) was 1.248 - 17.953,P = 0.030] and hypertonic albumin infusion used in 4 days after delivery [OR = 6.632, 95%CI was 1.211 - 16.328,P = 0.029] were the independent risk factors to develop ARF.Conclusions The occurrence of ARF in a critically ill obstetric patient in ICU is a process involving multiple factors, therefore, it is necessary to fully recognize the risk factors influencing the development of this disease; the presence of HELLP syndrome and hypertonic albumin infusion used in 4 days after delivery are the independent risk factors of developing ARF. Thus, particular attention should be paid to those patients with such high risk factors to decrease the incidence of ARF.

Acupuncture was frequently used for alternative treatments in Parkinson's disease because of its safety,but there was an argument whether acupuncture improves motor symptoms or not.Besides,few electrophysiological studies were designed for acupuncture combined with Parkinson's disease Using the technique of paired transcranial pulse magnetic stimulation,we measured the excitability of corticocortical inhibitory circuits to investigate effects of scalp acupuncture from 9 patients with Parkinson's disease.Although patients didn't take any short-term benefit in motor symptoms through the treatment of scalp acupuncture,there was no any adverse event,and some electrophysical effects developed in patients.The enhanced corticocortical inhibition on motor cortex possibly developed at longer interstimulus intervals,and there was a relatively increase in later part of motor-related cortical potentials on the central part and right-side near vertex around over sensory cortex,but was not significant in early potentials.So a further long-term study is essential to ascertain the physical mechanism and clinical effects in scalp acupuncture.

This study was aimed to investigate short-term modulation mechanism of scalp acupuncture according to the experimentation of cortical excitability and motor-related cortical potentials in ten normal volunteers.Through scalp needle stimulation in specific theoretical areas related to underlying cerebral surfaces,scalp acupuncture can be used as an effective therapy by changes in relative cerebral function,which is the basic principle.According to the available neurophysiological data in our study,the modulation of scalp acupuncture displayed in late part of motor-related cortical potential noticed mainly in the motor and sensory cortexes,contralateral to the needle stimulate site.Also,acupuncture can develop inhibition at longer interstimulus intervals,in paired pulse magnetic stimulation,from the somatosensory input of contralateral sensory cortex via scalp needle stimulation.In our study,it might be difficult to produce more acupuncture inhibition.The maintaining of scalp needles subcutaneously without other management after achieving needling sensations cannot achieve the requested strength of the acupuncture stimulation.

BACKGROUND: Therapist-assisted treadmill training is good gait training, but it consumes great physical strength of therapists, and requires many persons. Clinical application was limited. Robot-assisted treadmill training has been paid great attention. OBJECTIVE: To summarize the role of robot in recovery of walking after spinal cord injury (SCI) and its influence on muscle activation patterns and kinematic patterns.RESULTS AND CONCLUSION: Although there is currently no evidence that robot-assisted gait training improves walking function more than other locomotor training strategies. Several advantages of robotic devices are obvious for applications targeting gait rehabilitation. Robotic devices are passive in nature and focus primarily on repeated movements of the limbs via fixed kinematic trajectories. These types of training abolish the cycle-to-cycle variation in the kinematics and the sensorimotor pathways. They also cannot sensitively monitor important characteristics of the training as therapists do. Therapists need to know the robot devices, understand how to change parameters to continuously challenge the subjects, and are able to assess when the workload is inappropriate for the subject's abilities so that they can maximize voluntary locomotor performance during assisted stepping to augment the recovery of functional walking.
