Objective To investigate the axonal lesion in chronic inflammatory demyelinating polyneuropathy(CIDP).Methods Eighteen patients had undergone sural nerve biopsy.The clinical and electrophysiological distinction based on the different pathological changes were analyzed.Results Five patients with demyelination predominance which presented myelinated fiber with thin myelin.Three of them showed also mild axonal degeneration.Eight patients with axonal lesion predominance which presented Wallerian degeneration and regeneration of myelinated fibers.Three patients with mixed myelin and axon lesion of myelinated fibers and two with mild lesion.There was no significant difference between CIDP predominantly with axonal lesion and demyelination.Electrophysiological examination shows both axonal lesion and demyelination feature in some of the 2 types patients at the same time.Conclusions Axonal lesion is a common pathological change in CIDP and should not be considered as an exclusive criterion in diagnosis of the disease.Infiltration of macrophages is a common change.

Objective To investigate the relatonahip between TNF-α and ventricular arrhythmias after acute myocardial infarction(AMI)and its mechanism.Method Both the clinical and animal experiments were done.(1)Clinical experiment:Eighty patients with AMI were included in Union Hospital,Tongji Medical College,Huazhong University of Science and Techology,from May 2005 to November 2006 according to the WHO diagnostic criteria.Co-infection of diseases such as severe upper respiratory infection,lung infection,high fever,cancer,et al were excluded.The relationship between the levels of TNF-α and arrhythmias were observed at different times after AMI.A straight line correlation,analysis Was done.(2)Animal experiment:Different concentrations of TNF-αwere added to isohted rat hearts for observing the arrhythrnia effects.The effect of TNF-α on intracellular Ca2+ concentration was detected by laser confocal technique.All data were analyzed by SNK-q test using SPSS 13.0 sofeware prograrn.Results(1)The plasma levels of TNF-α were significantly associated with the Lown class of PVC after AMI and they were higher in AMI of anterior wall[(46.41±10.34)pg/ml]than other positions [(28.25±6.35)pg/ml,P<0.05].2)The frequency of ventricular arrhythmias was interrelated with the concentralions of TNF-α.Using etanercept beforehand,TNF-α induced a slight increase of intracellular Ca2+ intensity (P<0.05).Conclusions There was a relationship between TNF-αlevels and ventricular arrhythmisa in patients with AMI.Animal experiments confirmed the isolated heart perfusion with TNF-α induced ventricular arrhytrnias.Expression of TNF-α after AMI was related with the occurrence of ventricular arrhythrnias.The effect might be associated with the increased inuaeellular Ca2+ intensity caused by TNF-α.

Objective: To observe the clinical efficacy of deep electroacupuncture (EA) at Baliao points in treating stress urinary incontinence (SUI). Methods: A total of 60 female patients with SUI were divided into two groups according to the order of consultation, with 30 cases in each group. The control group was treated with pelvic floor muscle training. The treatment group was treated with deep EA at Baliao points [Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33) and Xialiao (BL 34)]. Results: The total effective rate was 93.3％ in the treatment group, versus 33.3％ in the control group, and the total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). After treatment, the scores of international consultation on incontinence questionnaire-short form (ICIQ-SF) and the volume of urinary leakage in both groups were lower than those before treatment (all P<0.05), and the ICIQ-SF score and the volume of urinary leakage in the treatment group were lower than those in the control group (both P<0.05). Conclusion: Deep EA at Baliao points with long needles can improve the clinical symptoms in female patients with SUI, and it has a better curative effect than pelvic floor muscle training.
