ObjectiveTo study the changes of serum immune state in maintenance hemodialysis (MHD) patients with high-flux hemodialysis. MethodsSixty MHD patients were divided into high-flux hemodialysis group (group T, 30 cases, receiving high-flux hemodialysis, 3 times per week and routine drug therapy) and conventional dialysis group (group C, 30 cases, taking conventional dialysis, 3 times per week and routine drug therapy) by random number table. They were treated for 12 weeks. Serum IgG,IgA, IgM,C3, C4, T lymphocyte subsets and albumin, prealbumin, hemoglobin were detected at the experiment onset and 12 weeks later, and compared with those of 20 normal medical examination adults (group N ), meanwhile the ratio of infection was calculated. ResultsThe levels of IgG,IgA,IgM,C3,C4,CD3+,CD4+,CD4+/CD/8+ in group C had no significant changes before and after treatment (P ＞ 0.05 ), but there were significant changes in group T[(12.20 ± 3.98) g/L vs.(6.18± 1.45) g/L, (1.89 ±0.58) g/L vs. (0.63 ±0.15) g/L, (1.29 ± 0.47)g/L vs. (0.51 ± 0.13) g/L, (0.94 ± 0.36) g/L vs.(0.58 ± 0.20) g/L, (0.28 ± 0.06) g/L vs. (0.11 ± 0.04) g/L,(63.11 ± 9.43 )％ vs. (53.26 ± 9.08 )％, ( 38.21 ± 6.15 )％ vs. ( 31.56± 6.02 )％, 1.48 ± 0.37 vs. 1.25 ± 0.43](P＜ 0.05), and there were significant differences between group T and group C after treatment (P＜ 0.05).The ratio of infection in group T was decreased obviously [46.7％ (14/30) vs. 133.3％ (40/30), P ＜ 0.05], but there was no significant difference in group C [126.7％(38/30) vs. 136.7％(41/30),P＞ 0.05]. Conclusion High-flux hemodialysis can improve the immune state and the nuuitional state in MHD patients, and it could decrease the infection rate.

Objective To investigate methods and experience of autologous granular fat transplantation by correction of aging face. Methods 178 cases of aging face subjects were treated by liposuction. Then autologous granular fat was harvested by liposuction,centrifuged and purified, and injected into marked areas of aging face. The injection process should be controled by multilevel and multiple tennel, in order to supplement the loss of facial soft tissue volume and improve the aging face. Results The follow-up period ranged from 3 months to 3 years. All the subjects had a satisfactory results with no obvious complications such as fat liquefaction, infection and ulceration. The effect of autologous granular fat transplantation was obvious and permanent. Conclusions Autologous granular fat transplantation is a safe and effective surgical technique for facial soft tissue augmentation that can effectively improve aging face and worthy of clinical application.
