OBJECTIVETo observe the polymorphism and gene frequency of interleukin 6 (IL6) gene -572C/G in Chinese Han nationality population, that associating with susceptibility to myocardial infarction(MI) and impacting on the extent of coronary artery lesions; to analyze the function of IL6 gene -572C/G polymorphism.

METHODSWith PCR-RFLP method, IL6 gene -572C/G polymorphism was genotyped to 232 MI patients and 260 healthy adults. The effect of IL6 gene -572C/G polymorphism was observed to the extent of coronary artery lesions and the ability of IL6 production from peripheral blood mononuclear cells (PBMC).

RESULTSThere was IL6 gene -572C/G polymorphism in Chinese Hans. -572CG+GG genotype and G allele were more frequent in patients than in controls (P< 0.01). The relative risk for G allele carrier to suffer from MI was 1.68 times of CC genotype individual (95%CI 1.17-2.41, P< 0.01). However, the distribution of IL6 gene -572C/G polymorphism was no significant difference among patients with single-vessel, two-vessel and three-vessel lesions (P> 0.05). After PBMC cultured for 24 hours, the IL6 concentration in supernatant was significantly higher in subjects with CG genotype than those with CC genotype (P< 0.05).

CONCLUSIONIL6 gene -572G allele may be a genetic susceptibility factor to MI attack of Chinese Hans population, and related to the high expression of IL6.

·AIM: To study the therapeutic method of XL -radiofrequency ablation skin apparatus (invented by Rehabilitation medicine, PLA General Hospital) in micro-resecting the lacrimal punctum neoplasm and to observe its clinical effects. ·METHODS:XL-radiofrequency ablation skin apparatus was performed on 7 cases (7 eye lesions) of lacrimal punctum neoplasm including 3 intradermal nevus, 1 boundary nevus, 1 mixed nevus with inflammatory granuloma,1 inflammatory granuloma,and 1 squamous papillary cell tumor by separating layer, point and flake removing methods. The clinical effect was investigated 2-6mo postoperatively and leftover was removed by twice. The postoperative follow- up durations ranged from 6 to 60mo. ·RESULTS: Totally 6 cases (6 eye lesions) were cured successfully by once but 1 case by twice. They were all without recurrence, cicatrix, palpebral margin deformity, obstruction of lacrimal punctum, stenosis of lacrimal punctum or epiphora. Micro - resecting the lacrimal punctum neoplasm using the XL-radiofrequency ablation skin apparatus had several advantages, such as high accuracy,no cicatrix,no bleeding,no epiphora,no damage to the structure of lacrimal canaliculus, short operation time, little pain during the procedure, without hospitalization, slight inflammation reaction after procedure. ·CONCLUSION: The efficacy of XL - radiofrequency ablation skin apparatus is significantly more evident and highly accurate in micro - resecting lacrimal punctum neoplasm.

Objective To investigate the effects of transcranial direct current stimulation (tDCS) on motor function of upper limbs of stroke patients. Methods 80 stroke patients were randomly divided into experimental group and control group. Both groups accepted routine rehabilitation, while the experimental group accepted anodal stimulation, and the control group received sham stimulation. They were assessed with Brunnstrom stages of arms and hands, Fugl-Meyer Assessment (FMA) of upper extremities, Action Research Arm Test (ARAT), Motor Assessment Scale (MAS) and modified Barthel Index (MBI) before and 1 month after treatment. Results All the scores improved in both groups after treatment (P<0.05), and improved more in the Brunnstrom stages of arms and hands, FMA, ARAT in the experimental group than in the control group (P<0.05). Conclusion tDCS may promote the recovery of arms and hands function of stroke patients.
