To combine "the rule of military medical measurement" with the current situation of medical treatment quality control, the foundation, important component and necessary condition of medical treatment quality control was described. Some idiographic advices of intercoordination and communication in medical measurement institution, the direction and training of special technique, and how to develop compulsion coerciveness checking in base course were given. These are valuable for insuring medical treatment facility in hospital.

The effects of Trichostatin A (TSA) on histone deacetylase 8 (HDAC8) expression, proliferation and cell cycle arrest in T-lymphoblastic leukemia cell line Molt-4 cells in vitro were investigated. The effect of TSA on the growth of Molt-4 cells was studied by MTT assay. Flow cytometry was used to examine the cell cycle. The expression of HDAC8 was detected by using immunocytochemistry and Western blot. The results showed that proliferation of Molt-4 cells was inhibited in TSA-treated group in a time- and dose-dependent manner. The IC50 of TSA exposures for 24 h and 36 h were 254.3236 and 199.257 microg/L respectively. The cell cycle analysis revealed that Molt-4 was mostly in G0/G1 phase, and after treatment with TSA from 50 to 400 microg/L for 24 h, the percents of G0/G1 cells were decreased and cells were arrested in G2/M phase. Treatment of TSA for 24 h could significantly inhibit the expression of HDAC8 protein in Molt-4 cells (P<0.01). It was concluded that TSA could decrease the expression of HDAC8 in Molt-4 cells, which contributed to the inhibition of proliferation and induction of cell cycle arrest in Molt-4 cells.

AIM: To analyze and summarize the effect of glaucoma trabeculectomy in the department of ophthalmology in basic hospital.
METHODS: Postoperative intraocular pressure ( IOP ) , filtering bleb and complications of 316 cases (405 eyes) of patients with glaucoma after trabeculectomy were analyzed.
RESULTS: After follow- up 12mo, 76. 5% IOP was controlled in normal level. 42. 5% was filtration bleb typeⅠ, 33. 1% typeII, 14. 6% in typeⅢand 9. 9% in typeⅣ. Intraoperative complication rate was 2. 5%, that was 31.4% at postoperative early stage ( before discharge ) , and 6. 7% at postoperative long - term ( 6mo after discharge) .
CONCLUSION:Trabeculectomy for glaucoma can better solve the problem of high IOP. It is more mature in primary hospitals, but there are still a variety of intraoperative and postoperative complications.

BACKGROUND:Normal stem cells and tumor stem cells have differences in cellsignaling pathway of gene expression and dependence. How to find a therapeutic method of selectively kil ing tumor stem cells is a topic that should be studied greatly. OBJECTIVE:To isolate human liver cancer stem cells MHCC97 and to investigate the biological characteristics of them. METHODS:Tumor stem cells were selected from highly metastatic human hepatoma cellline MHCC97 by flow cytometry. CD133-CD34-MHCC97 from normal human liver stem cells and CD133+CD34+MHCC97 from tumor stem cells were isolated. Their phenotypes, growth curve, cellcycle and multi-lineage differentiation were measured. RESULTS AND CONCLUSION:Phenotypes of CD133+CD34+MHCC97 cancer stem cells were CD133+and CD34+and they had the same growth curve and cellcycle with the liver stem cells CD133-CD34-MHCC97, besides, they had the differential ability to epithelial cells and endothelial cells that proved to be stem cells. These results indicated that human cancer stem cells CD133+CD34+MHCC97 had the specific characteristics of tumor stem cells, could differentiate into epithelial cells and endothelial cells, had the biological property of tumor stem cells, was an origin of tumor relapse and metastasis, and a target of clinical therapy.

Objective To study the effect of SDF1/CXCR4 and FN/?1 integrin modulated by curcumin on the adhesion and migration of B lymphoma Raji cell and to explore the mechanism of curcumin to inhibit the invasiveness of lymphoma.Methods The experiment consisted of eight groups: Control,FN,SDF,FN+anti-?1 integrin,SDF+anti-CXCR4,curcumin+FN,curcumin+SDF.Adhesion assay and migration assay were used to detect the difference of invasiveness among different groups.Results In vitro,SDF1 and FN can increase the adhesion and migration of Raji cells,which can be blocked by ?1 integrin antibody and CXCR4 antibody.Curcumin can inhibit the adhesion and migration of Raji to FN in a dose-dependant manner.Low dosage curcumin had minimal effect on the adhesion and migration of Raji induced by SDF except that 25?mol/L curcumin can inhibit the adhesion and migration of Raji.Conclusion FN/?1 integrin and SDF1/CXCR4 pathway play important roles in the adhesion and migration of Raji cells.Curcumin can decrease the invasiveness of Raji cells through inhibiting FN/?1 integrin.It has good prospect of clinical application.

Objective:To investigate the influence ofpidotimod combined with budesonide aerosol inhalation on the IL-4,IFN-γ,immunoglobulin and T cell subsets of children with bronchial asthma.Methods:92 cases of children with bronchial asthma in our hospi tal from June 2015 to June 2016 were selected as the research objects and randomly divided into the observation group and the control group.The control group was given budesonide suspension treatment,and the observation group was treated by pidotimod oral liquid on the base of the control group.The changes of serum IgA,IgG,IgM,CD3+,CD4+,CD8+ and CD4+CD8+ before and after treatment were de tected and compared between the two groups.Results:Before treatment,there was no significant difference in the serum IL-4,IFN-γ,IgA,IgG,IgM,CD3+,CD4+,CD8+ and CD4+/CD8+ between two groups (P＞0.05).Compared with those before treatment,the serum level of IL-4 was significantly decreased,in the observation group,while the IFN-γ,IgA,IgG,IgM,CD3+,CD4+,CD4+/CD8+ levels were significantly increased afrer treatment (P＜0.05).The IFN-γ,IgA,IgG,IgM,CD3+,CD4+,CD8+ and CD4+/CD8+ of control group showed no significant change before and after treatment (P＞0.05),only the serum IL-4 level was significantly decreased (P＜0.05).After treatment,the IL-4,IFN-γ,IgA,IgG,IgM,CD3+,CD4+,CD8+ and CD4+/CD8+ of observation group were better than those of the control group (P＜0.05).Conclusion:Compared with budesonide alone,pidotimod combined with budesonide could significantly regulate the immune function of children with bronchial asthma.

To investigate whether the Bcl-2 gene family is involved in modulating mechanism of apoptosis and change of cell cycle protein induced by curcumin in acute myeloid leukemia HL-60 cell line and primary acute myelogenous leukemic cells, the Bcl-2 family member Mcl-1, Bax and Bak and cell cycle proteins including P27kipl, P21wafl, cyclin D3 and pRbp- were selected and their expression detected by SABC immuno-histochemical stain method. The attitude of sub-G1 peak in DNA histogram was determined by FCM. The TUNEL positive cell percentage was identified by terminal deoxynucleotidyl transferase (TdT)-mediated Biotin dUNP end labeling technique. It was found that when HL-60 cells were treated with 25 mumol/L curcumin for 24 h, the expression level of Mcl-1 was down-regulated, but that of Bax and Bak up-regulated time-dependently. There was significant difference in the expression level of Mcl-1, Bax and Bak between the curcumin-treated groups and control group (P < 0.05-0.01). At the same time, curcumin had no effect on progress of cell cycle in primaty acute myelogenous leukemia at newly diagnosis, but could increase the peak of Sub-G1 (P < 0.05), and down-regulate the expression of Mcl-1 and up-regulate the expression of Bax and Bak with the difference being statistically significant. The expression of P27kipl, P21wafl and pRbp- were elevated and that of cyclin D3 decreased in the presence of curcumin. These findings suggested that the Bcl-2 gene family indeed participated in the regulatory process of apoptosis induced by curcumin in HL-60 cells and AML cells. Curcumin can induce apoptosis of primary acute myelogenous leukemic cells and disturb cell cycle progression of HL-60 cells. The mechanism appeared to be mediated by perturbing G0/G1 phases checkpoints which associated with up-regulation of P27kipl, P21wafl and pRbp- expression, and down-regulation of cyclin D3.
