The spleno-and thyme-lymphocytes of mice were cultured in the media with various concentrations of zinc. The results showed that zinc acted as a weak mitogen and stimulating lymphocyte proliferation at 0.12-0.5? 10-4 mol/L. It also enhanced the lymphocyte proliferation to Con A and LPS. The optimal concentration was 0.12?10-4mol/L. It enhanced the MLR of spleno-lym-phocyte and increased the responsive ability of thymocyte to IL-1. Zinc was poisonous to cells at concentrations higher than 1.0 ?10-4mol/L.

Objective:To assess the life quality of the patients with tongue cancer after operation.Methods:80 cases of tongue cancer following surgery during 1994 to 1998 were reviewed with questionaire.Scords of University of Washington Quality o f Life (UW-QOL) were analysed to evaluate their life quality.Results:(1) 3-year survival rate was 72.5%,higher survival rate was observed in the patients with I and II stage lesion than those with Ⅲ and Ⅳ stages.(2) 58 cases of survivers had UW-QOL average score of 618. Some patients had serious disability in mastication, swallowing,speaking and shoulder movement.(3)Patients retaining mandible or with skin flap repair had higher quality of life than the others.Conclusion:Following surgery,tongue cancer patients still maintain comparatively high quality of life.Reconstruction of mandibular or tongue is very importent for the life quality of the patients.

After mice swam for one to three weeks, the splenic mononuclear cells (MNC)were measured by flow cytometry. The data showed that the trained mice MNCnumber decreased (trained group: 36.6? 16.6?10~6/spleen; control group: 62.4?21.6?10~6/spleen, P

The nutritional survey was made in 184 anorexia children aged 3-7, 123 of them were treated with various measures for three months. The results indicated that the children with anorexia had low intake and deficiency in energy, protein, minerals and vitamins. Most of them had zinc deficiency, but they simultaneously had two to three nutrients deficiency.The zinc treatment could improve most patient's syndrome and nutritional status. The effect of zinc treatment with vitamines and iron preparations was better than zinc treatment only. The effect of treatment with Chinese medicine also was able to cure the children with anorexia to certain extent.

Objective To investigate the effect of tripterygium wilfordii hoffF on acute immune rejection of bone xenograft in mice.Methods Male Neijiang swine and BALB/c mice were used as donor and receipts,respectively.Forty mice were divided into experimental group and control group at random.The mice in experimental group were administered intragastrially with tripterygium wilfordii hoofF before bone xenograft.At two weeks postoperatively,CD4+,CD8+,CD4+/CD8+ T lymphocytes in spleen were detected by flow cytometry,and the levels of IL-2,IFN-? and IL-4 in blood were analyzed by quantitative ELISA assay.And the infiltration of lymphocytes and macrophages surrounding soft tissues of bone graft was also observed in order to evaluate the immunosuppression of tripterygium wilfordii hoof-F.Results At two weeks postoperatively,compared with control group,CD4+,CD8+,CD4+/CD8+ T lymphocytes in spleen,the levels of IL-2,IFN-? and IL-4 in blood of mice in experimental group were significantly decreased(P

Objective The vertical mammaplasty improves the breast morphology,and reduces the operative scar.However,the nipple-and-areola complex (NAC) has the risk of necrosis on those severe patients.In this report,we performed the vertical incision scar reduction mammaplasty based on Würinger's horizontal septum to reduce the NAC necrosis possibility.Methods Typical Lejour mosque-dome design was performed.The inferior part of glandular tissue and skin were excised.The NAC was elevated to normal position with medial-superior pedicle based on the horizontal septum.The breast morphology was modified with lateral and medial glandular pillar suturing using nonabsorbent thread.For reducing the vertical scar,the lower breast flap was thinned to induce the skin contraction.Results 27 patients with breast hypertrophy were operated from May 2009 to October 2012.1 patient had unilateral breast reduction,and 6 patients with 8 breasts had partial wound dehiscence.They were treated conservatively with topical dressings.No complete NAC necrosis occurred.Conclusions The vertical reduction mammaplasty based on Würinger's horizontal septum is a safe and effective approach,and the NAC necrosis possibility is reduced with this procedure.
