Objective:To evaluate the clinical effect of combination of autologous tissue reconstruction of tarsal plate with temporal flap on repair of full-thickness lower eyelid defect.Methods:Eleven patients (11 eyes) underwent hard palate mucosa or ear cartilage combined the emporal flap with the orbicularis oculi muscle to repair full-thickness defect ofpalpebra inferior.Of the 11 patients,6 had more than 75％ eyelid defect area,and 5 had more than 50％ eyelid defect area.Results:All 11 eyes closed completely,with no entropion or ectropion,and returned to normal basically.Postoperative follow-up was performed for 6 months to 5 years,3 years and 4 months on average.The function and form of eyelid remained stable.Infection,leakage or contracture was not found on reconstruction tarsus.Conclusion:Reconstruction of eyelid with autogenous hard palate mucosa or ear cartilage combined the emporal flap with the orbicularis oculi muscle is a simple,convenient and effective method.

Objective To evaluate the advantages of plasma cell enrichment combined with fluorescence in situ hybridization (FISH) based on a panel of probes by the conventional cytogenetic (CC) analysis.Methods Fresh heparinized bone marrow samples were collected by bone marrow biopsy.Plasma cells were enriched in BM samples using a magnetic cell-sorting procedure to select CD138+ cells.The common chromosome abnormalities of MM were detected by FISH based on a panel of probes and CC analysis after short-term culture of the BM cells,in order to compare the differences between these two methods for the frequency of common cytogenetic abnormalities.Results 72 of 95 (75.8％) MM patients were found to carry clonal chromosome abnormalities by FISH.And RB 1 deletion was the highest at 44.2％ (42/95) followed by CKS1B (1q21) amplification (42.1％).The frequencies of CDKN2C (1p32) deletion,TP53 deletion,IGH/CCND1 and IGH/FGFR3 were 8.4％ (8/95),12.6％ (12/95),14.7％ (14/ 95) and 14.7％ (14/95),respectively.IGH/MAF was negative.Thirty-two of 95 (33.7％) patients were found to carry clonal aberrations by CC analysis.The frequency of chromosome abnormalities detected by FISH was significantly higher than CC analysis (75.8％ vs 33.7％,P =0.000).Conclusion Plasma cell enrichment combined with FISH based on a panel of probes can greatly increase the frequency of chromosome abnormalities,which provides cytogenetic basis for risk stratification and prognosis of MM patients.

Objectives To investigate the relationship between angiogenesis and vascular endothelial growth factor (VEGF) and its receptor in patients with psoriasis. Methods The expression of VEGF and its receptor KDR, and micro-vascular density (MVD) were measured in 42 patients with psoriasis vulgaris and 15 normal controls by in situ hybridization and immunohistochemistry technique, respectively. The concentration of VEGF in sera was measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in patients with psoriasis vulgaris and normal controls. Results ①The expression of VEGF mRNA and its protein, KDR, and MVD in psoriatic lesions were significantly higher than those in the normal controls (P

Objective:To explore effects of trehalose as a cryopreserve agent on survival rate of fatty tissue after cryopreservation.Methods:The liposuction was used on the abdomen of adult female.After centrifugation and purification,adipose was randomized into the following three groups,the trehalose group,the fetal bovine serum (FBS)+ 10％DMSO group and the physiological saline group.The specimens were cryopreserved at-196 ℃ for 3 months and then the HE staining,glucose transfer method and CK method were used to detect the cell survival rate in each group.Results:The activity of adipose in the trehalose group and FBS+10％DMSO group adipose was higher than that in the physiological saline group (P＜0.05);while there was no significant difference between the trehalose group and FBS+10％DMSO group (P＞0.05).Conclusion:As cryoprotectant,trehalose could keep fat cell viability,and adipose tissue can be used for clinical transplantation after 3 months' freezing.

Objective To evaluate narrow band imaging (NBI) assisted argon plasma coagulation (APC) in treatment of Barrett's esophagus (BE). Methods Suspected BE lesion was observed under white light, NBI and magnification, biopsies were taken at the site with characteristic pit pattern and capillary architecture of BE. A total of 86 patients with pathologically confirmed BE were randomly divided into NBI group (n= 42) to receive APC under NBI, or control group (n= 44) to receive APC under whit light. For APC procedure, the probe was inserted through biopsy channel to reach 1 cm beyond the endoscope tip, and was located 1-2 cm from the lesion to assure safe use. All patients were followed up with endoscopy and biopsy at 3 and 6 months after APC, respectively. Results There was no significant difference between 2 groups in effective rate of BE mucosal eradication at 3 and 6 months after APC procedure (P > 0.05). Conclusion NBI assisted APC is safe and effective in eradication of BE epithelium, in reducing procedure time and in relieving of functional gastrointestinal symptoms related with BE.

Objective To analyze the clinical features and prognosis of CD34-positive and CD34-negative adult patients with acute T-lymphoblastic leukemia (T-ALL),and to explore the value of CD34 expression for prognosis of patients with T-ALL.Methods 75 adult patients diagnosed with T-ALL from January 2012 to July 2015 in the Department of Hematology,the First Affiliated Hospital of Zhengzhou University,were analyzed retrospectively.According to the expression of CD34,the patients were divided into CD34-positive group and CD34-negative group,and then the clinical characteristics and prognosis of both groups were analyzed.Results In 75 patients,CD34-positive group had 24 (32.0 ％) patients and CD34-negative group had 51 (68.0 ％) patients.Between the two groups,there was no significant difference in these factors,such as sex,age,infiltration of liver,spleen and lymph nodes,thrombocytopenia,high white blood cell count,abnormal karyotype,complete remission within 4 weeks and central nervous system leukemia (CNSL).The proportions of patients with hemoglobin (Hb) ＜ 90 g/L and expression of myeloid lineage marker were higher in the CD34-positive group than those in the CD34-negative group (x2 =5.888,P=0.015;x2 =10.758,P =0.001,respectively).There were only 18 patients treated with hematopoietic stem cell transplantation (HSCT),57 patients were not.In patients without HSCT,the median survival time in the CD34-positive group and CD34-negative group was significant different (5 months vs.32 months,x2 =9.172,P =0.002).Conclusions CD34 expression in adult patients with T-ALL appears to be associated with Hb ＜ 90 g/L and the expression of myeloid lineage markers.For the patients without HSCT,CD34 is likely negatively related with the prognosis.

Objective To observe curative effect and clinical outcome in 30 recipients undergoing allogcneic peripheral blood stem cell transplantation (PBSCT) combined with bone marrow transplantation (BMT). Methods 30 patients with a median age of 32.6 years underwent allo-HSCT, of which 11 patients with AML, 14 patients with ALL, and 5 patients with CML They all have a HLA-identical sibling. PBSCswere mobilized with G-CSF. Three hundreds milliliter bone marrow blood was transplanted to the patients on the day that the PBSC was transplanted. Amended Bu/Cy was used as the conditioning regimen. MTXcombined with CsA and MMF was used as GVHD prophylaxis. Results A median number of mononuclear cells of (5.13±2.6)x10~8/kg recipient's weight was collccted from peripheral blood, and (1.3±0.6)x10~8/kgrecipient' s weight from bone marrow blood. Engraftment of neutrophils and platelets was achieved at a median of (12.1±3.25) days and (14±5.33) clays respectively. Ⅰ - Ⅱ acute GVHD occurred in 40.0 % cases,Ⅲ - Ⅳ acute GVHD occurred in 3.3 % cases, and chronic GVHD developed in 43.3 % cases. Severe cGVHD developed in 3.3% cases. The 2 years disease free survival rate (DFS) by the day of transplantation was 72.0 %. Conclusion PBSCT combined with BMT was effective to cure leukemia. The results also suggested that PBSC recipients had an lower incidence of aGVHD and cGVHD as compared with previous reports.
