Objective To study the regulatory T cells (Treg-cell) frequencies in patients with childhood acute leukemia and evaluate its clinical application value by investigating the relationship between the increasing numbers of Treg cells and minimal residual disease of leukemia (MRD), Methods Foxp3-FITC/CD25-PE/CD4-PerCP/CD3-APC four-color staining flow cytometry was established to identify Treg cells. Treg cells frequencies both in 10 healthy controls and in 33 patients with newly diagnosed childhood acute leukemia ( B-ALL 17 cases, T-ALL 9 cases, AML 7 cases) were detected. The possibility of the accumulation of Treg cells being the prognostic marker for acute leukemia was evaluated by comparing the results of Treg cells frequency with that of MRD. Results The percentage of Treg cells in CD+4 CD+3 T cells was M = 8. 09% in normal bone marrows, which was significantly different from the results in the bone marrows of newly diagnosed childhood acute leukemia ( M = 12.77% , U = 3.41, P < 0.01 ), but it showed no significantly differences among B-ALL, T-ALL and AML groups. No association was observed between the expression of Treg cells and clinical-biologic characteristics studied. In addition, Treg cells frequency in MRD positive group was significantly different from that in MRD continuously negative group ( M = 14. 74% vs M=11.3%, t =252.5,P<0.05). Conclusions Consistent with results from solid tumor, the study identifies a significantly increased numbers of Treg cells in patients with childhood acute leukemia. The situation of accumulation of Treg cells is closely associated with MRD results during chnical remission. High level of Treg cells may cause poor prognosis and increase the possibility of relapse.

The establishment of quality evaluation of traditional Chinese medicine system that not only accords with Chinese medicine function characteristics but also is recognized as international medical circles, is an arduous task in urgent need of solving the current modernization of traditional Chinese medicine in the process of internationalization. It is difficult to evaluate atraditional Chinese medicine by detection of single active components in traditional Chinesemedicinewiththe western medicine quality controlmethod due to the overall effects of traditional Chinese drugs, the components of the overall diversity, targets, and the complexity of the interaction between components of unpredictable make the Long-term since, domestic and foreign scholars continue to explore and put forward a series of quality evaluation of traditional Chinese medicine to promote the development of traditional Chinese medicine. This article summarized the related academic ideas and developments to, providea new thought and perspective for the quality control of traditional Chinese medicine.

Objective To investigate the effect of lobaplatin combined with irradiation on human nasopharyngeal cancer cell line CNE2,and to illuminate its mechanism of radiosensitization.Methods MTT assay was used to detect the outcome of lobaplatin and irradiation on CNE2 cell proliferation.Clonogenic assay was applied to testify the radiosensitization effect of lobaplatin on the cells.Flow cytometry was used to check the cell cycle distribution and cell apoptosis.Western was used to detect the expression of Bcl-2,Bax and cleaved Caspase-3.Results The proliferation of CNE2 cells was reduced by lobaplatin in a dose-dependent manner.50IC of lobaplatin on CNE2 cells and lobaplatin combined with 4 Gy irradiation was 1.610 μmol/L and 0.077 μmol/L,respectively.The radiosensitization ratio of the combination group was over 3.Within 24 h of drug treatment,the percent of cells in G2/M phase increased with the concentration of lobaplatin.When the concentration of lobaplatin increased to 6 μmol/L,the cells of combination group were arrested at S phase.The apoptosis rate of lobaplatin (5 μmol/L) group,radiotherapy(4 Gy)group and combination group was 15.6％,11.3％ and 61.8％,respectively.Western blot showed that the expressions of Bax and cleaved Caspase-3 increased but Bcl-2 decreased in the combination group.Conclusion Lobaplatin could increase radiosensitization of human nasopharyngeal cancer cell line CNE2,probably by depressing Bcl-2 but enhancing Bax expression and hence activating Bcl-2/Bax-Caspase signaling pathway.

AIM: To investigate the efficacy, safety and localization of multilayer amniotic membrane transplantation (AMT) for the management of corneal perforation associated with ulceration.METHODS: Six eyes (6 patients) were treated with multilayer AMT for corneal perforation associated with ulceration. The perforation size was 0.5-2mm in diameter. The amniotic membrane (AM) was applied to tamp the perforation, fill the ulcer and cover the surface of ulcer. The follow-up ranged from 5-19 months.RESULTS: The anterior chamber reformed at the first postoperative day in all patients, and kept in normal depth in the follow- up time. The epithelialization of the AM grafts was observed in about 3 weeks after surgery. During the first postoperative month, the corneal thickness at the perforation site gradually increased, and the stromal inflammatory cell invasions surrounding the corneal ulcer were gradually subsided.Two months postoperatively, the ulcer healed with scar with part neovascutarization; the corneal thickness of the ulcer area was stable and recovered almost normal. The vision was not improved in all patients after operation. During-follow up,no severe complications or recurrence of ulceration was noted.CONCLUSION: Multilayer AMT is an effective and safe method for the management of small corneal perforation associated with ulceration, but the ulcer healed with scar.

AIM: To evaluate the efficacy and safety of annular bubble conjunctival excision combining with amniotic membrane transplantation(AMT) for vernal keratoconjunctivitis(VKC) with gelatinous swellings(papillae) at the limbus.METHODS: Twenty eyes(10 patients) with VKC, were characterized by gelatinous swellings(papillae) at limbus and were underwent annular bubble conjunctival excision associated with AMT. The follow up ranged 5-21months.RESULTS: After operation, the symptoms were subsided remarkably: itching,discharge and foreign body sensation were almost disappear; photophobia and tearing were obvious in the first week after surgery, but were gradually alleviated, and almost disappear after one month of postoperative.Yellow-brown or filthy red gelatinous protuberances at limbus were cleaned away by operation and did not recur during the follow up. Corneal superficial punctuate keratitis(11 eyes) and corneal ulcers(3 eyes) were healed during the first week after surgery and did not recur. Conjunctival congestion was gradually lessened after surgery, which could not be noted 1months after surgery in 19 eyes, and the conjunctiva around the limbus, where AMT was performed, was whiter than the normal. But conjunctival congestion in 1 eye lasted for about 5mon accompanying with a little of itch, and this eye was treated with eyedrops with improvement but recurrence. No severe complications had been seen during the follow up.CONCLUSION: Annular bubble conjunctival excision combining with amniotic membrane transplantation is an effective and safe method for the treatment of vernal keratoconjunctivitis with gelatinous swellings (papillae) at limbus. But the candidates must be chosen with discretion.

AIM: To investigate the efficacy and safety of annular conjunctival excision combined with amniotic membrane transplantation for the management of earlier Mooren's ulcer.METHODS: Thirty eyes (24 patients) with earlier Mooren's ulcer were treated with this method, followed-up for 5-30mo. The characteristic of these patients was localized periphery corneal ulcer: the ulcer involved 30-120° corneal limbus with depth of 1/3-1/2 cornealthickness and width of 2-5mm.RESULTS: After surgery, symptoms subsided remarkably and immediately in all patients,and almost disappeared after stitches were removed. Corneal melts were controlled. At postoperative 2-3mo, the corneal thickness of the ulcer area became almost stable, which in some patients recovered normal and in others were still thinner than normal, and the average increase was about 1/3 of the corneal thickness. Corneal transparence and vision were improved. During follow-up, no severe complications or recurrence were noted.CONCLUSION: Conjunctival peritomy combined with amniotic membrane transplantation is an effective and safe method for the treatment of earlier Mooren's ulcer.

Objective:To investigate the inhibitory effect of selective angiotensinⅡtype 1 receptor antagonist ZD7155 on pancreatic cancer xenografts of nude mice.Methods:Sixty nude mice were given subcutaneous injections of PaTu8988s cells to establish the pancreatic cancer xenograft models;then the animal models were evenly randomized into 3 groups:low-dose (10 mg?kg~(-1)?d~(-1))ZD7155,high-dose(20 mg?kg~(-1)?d~(-1))ZD7155 and normal saline groups.Ten mice in each group were sacrificed 10 d after treatment and the tumor sizes and body weights were measured.The microvessel density(MVD)was assessed by immunostaining of endothelial cells for CD31 and the cell apoptoses were observed by transmission electron microscope.Another thirty mice were treated for 30 days;the survival period of mice and toxicity of ZD7155 were observed till the 49th day of treatment.Results:Ten days after treatment,the mean tumor volumes in the control,low-dose and high-dose groups were(35.8?6.7)cm~3,(21.5?6.1)cm~3 and (10.7?4.1)cm~3,respectively(P
