BACKGROUND: The event of paroxysmal deplorizing shift (PDS) is the cellular hallmark of brain neurons of epileptiform activities. Its development used to be considered to be related to abnormal synaptic interactions. Recertly, the intrinsic nature of PDS has received more attention.OBJECTIVE: To observe the characteristics of epileptiform activities of rat hippocampal CA1 pyramidal neurons induced by low-dosage veratridine and investigate its possible ion mechanism.DESIGN: An exploratory and observational trial.SETTING: Institute of Neuroscience, Fourth Military Medical University of Chinese PLA.MATERIALS: This study was conducted at the Institute of Neuroscience,Fourth Military Medical University of Chinese PLA, from October 2002 to October 2004. Forty healthy SD rats of 14 days old were selected. Drugs were provided from Tianjin Drug Company and Sigma Company.METHODS: Rats were anesthetized by intraperitoneal injection, and their brain was removed and cut into slices. Epileptiform activities were induced by 0.5 μ mol/L veratridine. Then 80 nmol/L tetrodotoxin was added into the perfused solution on 6 cerebral slices, and 5 μmol/L phenytoin was used on another 5 cerebral slices. The electrophysiological characteristics of the cells under the effect of different kinds of drugs were observed.MAIN OUTCOME MEASURE: Discharge pattern of cells and tetrodotoxin-sensitive sodium currents under voltage-clamp configuration through Ⅰ-Ⅴ reaction.RESULTS: After perfusion of 0.5 μmol/L veratridine, the rat pyramidal neurons in CA1 area displayed relatively fixed-mode of runs of PDS bursting,followed by the hyperpolarization of cell membrane. Such epileptiform activities were blocked either by 80 nmol/L tetrodotoxin or 5 μnol/L phenytoin. The tetrodotoxin-sensitive sodium currents in epileptic neurons and normal controls under voltage-clamp configuration on holding potential of -55 rmV, -60 rmV, -65 mV. This shows that persistent sodium currents could be improved by low-dosage veratridine in a voltage-dependent manner.CONCLUSION: Low-dosage veratridine may induce runs of PDS like epileptiform activities on rat CA1 pyramidal neurons. Such changes can be blocked by low-dosage tetrodotoxin or phenytoin. Its ion mechanism may be related to persistent sodium currents.

Objective To observe the effect of body-weight supported treadmill training (BWSTT) on the lower limb motor function of elderly hemiplegia patients with acute cerebral infarction using semi-quantitative analysis of regional cerebral blood flow (rCBF) through single photon emission computed tomography (SPECT). Methods Seven patients with cerebral infarction were given comprehensive rehabilitation therapy for 10 weeks in three stages: a baseline period of 2 weeks ( conventional rehabilitation therapy), an intervention period of 6 weeks ( conventional rehabilitation therapy plus BWSTT) and a withdrawal period of 2 weeks (conventional rehabilitation therapy). During the intervention period the exercise duration increased gradually from 15 to 30 minutes, once a day, 5 times a week,for 6 consecutive weeks. Dynamic changes in rCBF in the cortex were observed with SPECT before and after treat ment. Results During the baseline period there was no significant change in average MWS (maximum walking speed) or BBS ( Berg balance scale) scores. During the intervention period both scores improved significantly. During the withdrawal period there were some changes in MWS and BBS scores, but they were not significant. There was a significant change in average rCBF in the cortex after treatment compared with before. Conclusions BWSTT is effective for improving the walking speed and balance of elderly patients with acute cerebral infarction. There is a positive correlation between the recovery of lower limb motor function and changes in rCBF in the cortex.

Objective To explore the influence of type A character on early renal impairment in elderly patients with essential hypertension and the protective effect of benazepril. Methods According to the type A behavior measuring scale, 80 cases with type A character and 80 cases without type A character were screened out from the elderly patients with essential hypertension. The patients received benazepril intervention with incipient dose of 10 mg daily, which increased gradually to the largest does of 20 mg daily within 1 month, The treatment lasted 6 months in order to make the patients achieve the normal blood pressure (BP). The general data, plasma angiotensin Ⅱ (AngⅡ )> urinary albumin excretion rate (UAER) and urinary β2-microglobulin (β2-MG) were measured at pretherapy and post-treatment respectively. Results There were no statistically significant differences at pretherapy between the two groups in age, gender, body mass index (BMI), blood urea nitrogen (BUN), creatinine (Cr), systolic pressure and diastolic pressure (all P>0.05). Ang Ⅱ [(60.3±11.6)mg/Lvs (55.8±10.2)mg/L], UAER[(83.3±23.3)μg/min vs. (75.7±16.3)μg/min] and β2-MG [(75.6±24.5)mmol/L vs. (66.0±19.4)mmol/L] were significantly higher in type A character group than in non-type A character group (t=2.598, 2.603, 2.742; P= 0.016,0.012, 0.008). TypeA character value of the two groups showed a positive correlation with Ang Ⅱ (r= 0.361, P=0.002), UAER (r=0.198, P=0.015) and β2-MG (r=0.202, P = 0.021). Only Ang Ⅱ (β=0.291, t=2.793, P= 0.008) was correlated to type A character value independently by multiple stepwise regression analysis. Before treatment in both of the type A character group and the non-type-A character group, there was a positive correlation between Ang II and UAER, (β2-MG, and obvious correlation in type-A character group. The systolic pressure, diastolic pressure, Ang Ⅱ , UREA and β2-MG were all decreased obviously in two groups post treatment. And the variable value of AngⅡ was also positively correlated with UAER (r=0.373, P=0.005; r=0.282, P=0.032), fr-MG (r= 0.385, P=0.003; r= 0.279, P=0.039) before and after treatment. Conclusions Type A character can aggravate injury of early renal function by certain stress systems in the elderly patients with essential hypertension and benazepril has better protective effect for it.

Objective To investigate the value of the manipulative reduction monitored by ultrasound for the intussusception of children.Methods One hundred and three intussusception children were dynamically observed by ultrasound,and were pressed softly beginning with the head of the intussusceptum,and observed whether there was intestinal peristalsis, and whether the intussuseeptum shortened and disappeared finally.The results were analyzed based on the size of the masse, the length of the intussusceptum,and the patients' age,and compared with the X-ray high pressure air enema.Results Fifty (48.5 ％) intussusception children were recovered.The recoverability was related to the size of the mass, the length of the intussusceptum, and the age of the children (level of cooperation).Thirty-nine patients were recovered after reexamined one hour later.The recoverability of manipulative reduction monitored by ultrasound for the mass diameter less than 2.0 cm was obviously higher than that by X-ray high pressure air enema.Conclusions Manipulative reduction monitored by ultrasound could cure almost half of the intussusception children patients directly.It could decrease the number of patients who were treated with high-pressure air enema,it could relieve the pain of the children and reduce their medical expenses.It also could be acted as a screening way to other therapies like high pressure air enema.

Objective To explore the effect of continuing care outside hospital on bone pain after multiple myeloma. Methods 82 multiple myeloma patients with bone hurt or bone pain were divided into experimental group (n=42) and control group (n=40). The control group received routine discharge guidance, and the experimental group received continuing care outside hospital in addition. Their knowledge of care and the rate of bone pain released just before and 6 months after discharge were observed. Results The score of knowledge test was (92.8±6.0) in the experimental group, more than (70.2±12.6) in the control group (P<0.001). The bone pain released in 90.5% of the experimental group, more than 72.5% of the control group (P<0.05). Conclusion Continuing care outside hospital may benefit to release bone pain after multiple myeloma.

Objective To compare effect of three therapies( modified constraint-induced movement therapy (mCIMT), constraint-induced movement therapy (CIMT) and Bobath therapies)on the recovery of motor function in upper-extremities of patients with apoplexy hemiparalysis. Methods Fifty-seven patients with apoplexy hemiparalysis were randomly divided into CIMT treatment group ( n = 19), mCIMT group (n = 19) and Bobath group (n = 19). Patients in Bobath group exercised 2 h/d, 5 d/week for 6 weeks. CIMT group and mCIMT group had restriction of movement at the unimpaired upper extremity by placing it in a sling a whole day for training using impaired extremity. Patients in CIMT treatment group exercised 6 h/d,5 days a week for 2 weeks in a row; mCIMT treatment group exercised for 1 h/d, 3 days a week, and also exercised in daily life at least 2 hours every day, for ten consecutive weeks. The patients in all three groups were assessed for upper-extremities motor function using FMA of Fugl-Meyer, for recovery of upperextremities motor speed using STEF and for recovery of daily ability at respective time-points of pre-treatment and the second week, sixth week and tenth week of post-treatment. Results In 3 assessments in the 3 groups there was no obvious change before treatment, while the FMA score was 45. 2 ± 5.1 (F = 1. 107 ,P =0. 382), BI score was 63. 1 ± 10. 3 ( F = 0. 930, P = 0. 401 ), STEF score was 63.4 ± 8.6 ( F = 1. 843, P =0. 168). At the second week, sixth week and tenth week of the treatment, the difference of assessment in the three groups was significant. The improvement in CIMT group was better after 2 weeks treatment compared with Bobath and mCIMT group, while the Bobath group showed better results than mCIMT group did after 6 weeks treatment. After 10 weeks treatment, the FMA, STEF in mCIMT and CIMT groups were improved better than Bobath group, while the BI score in mCIMT group was better than that in Bobath and CIMT group. Conclusions The mCIMT and CIMT therapy are better in improving the upper limb function in stroke patients compared with Bobath, while the mCIMT therapy is more effective in improving the abilities of daily life in stroke patients compared with the other two treatments.

Objective To construct and express human ScFv against keratin in E.coli,and identify its binding activity with antigens and antigenic specificity.Methods By genetic engineering technology,human anti-keratin ScFv was constructed from Fab fragment selected from established semi-synthetic phage antibody library.The binding activity with antigens and antigenic specificity of expressed products were i-dentified by ELISA.Results Results of DNA sequence analysis showed that nucleotide sequence of V?and VH of ScFv gene was similar to that of V?and VH of Fab gene,suggesting that there was no mutation in the construction of ScFv.The soluble anti-keratin ScFv was found to have a good antigenic specificity as well as excellent binding activity with target antigens by ELISA.However,the binding activity of ScFv with keratin was lower than that of Fab.Conclusions The successful expression and identification of human an-ti-keratin ScFv might lay a solid foundation for further observation of biological activities of anti-keratin au-toantibody,manufacture of genetic-engineering anti-keratin products,and promotion of clinical application of genetic-engineering anti-keratin antibodies.
