In recent years, monoclonal antibody comes to be a new and promising kind of treatment mode for malignant lymphoma, because of its advantages, such as target property, minimal residual of tumor cell in vivo and little side effect. The main methods include single agent therapy, combination with chemothera-py, combination with immunotoxin, radioimmunotherapy and etc.

Radionuclide imaging was widely used in the diagnosis and treatment of skeletal diseases.It is of early diagnostic value in metastatic osteosarcoma，osteomyelitis and Paget's disease,and early affirmative value in vitality of transplanted bone.It also demonstrates a significant analgesic effect on theosteosarcoma and metastatic osteosarcoma.

Objective To evaluate the in vivo efficacy of modified platelet(PLT) additive solution(PAS-ⅢM) with trehalose as a substitute for plasma for the storage of platelet concentrates at low temperature(10℃).Methods Rabbit platelet concentrates were collected and stored in different media and temperature conditions,plasma(22℃),70%PAS-ⅢM/30% plasma(10℃) and plasma/trehalose(-85℃).Platelets in plasma(22℃) on storage day 3,in 70%PAS-ⅢM/30% plasma(10℃) on storage day 3,7,9,and in plasma/trehalose(-85℃) thawed on day 20 were transfused to rabbit thrombocytopenia model.The in vivo recoveries and survivals of the three preserved platelets and fresh platelets were measured and evaluated after transfusion into rabit model of thrombocytopenia.Results The survival of platelets stored in 70% PAS-ⅢM/30% plasma(10℃) on day 9 was lower than that of fresh platelets(P0.05).Recovery and survival of frozen platelets were significant lower than those of the other groups(P

0.05).The off-pump group had a shorter respiratory support time [(4.8?1.9)h vs(8.9?2.1)h,t=17.453,P=0.000],less drainage volume[(390?152)ml vs(660?111)ml,t=17.173,P=0.000],and required less blood transfusion [(270?77)ml vs(510?144)ml,t=17.861,P=0.000] than the on-pump group.In the off-pump group,3(2.0%)of the 150 patients developed renal function injury that is significantly more than that in the on-pump group [11/140(7.9%),?2=5.407,P=0.020].Conclusions Off-pump CABG is as effective as the on-pump surgery;moreover,it is a better choice for patients with high-risk coronary disease since this technique is superior in reducing respiratory support time,volumes of chest drainage and blood transfusion,and renal function injury.

Objective To investigate the clinical effect of Edaravone on transient ischemic attack and serum superoxide dismutase and malondialdehyde levels in the elderly.Methods Ninety eight cases with transient ischemic attack treated in our hospital were chosen as the objects, which were randomly divided into observation group and control group (n=49 for each).Patients in observation group were treated with Edaravone combined with conventional therapy, and patients in control group were treated with conventional therapy.The clinical effect and levels of SOD and MDA were analyzed and compared between the two groups.Results The effective rate and total efficiency were higher in observation group than in control group (79.6％ vs.55.1％, 95.9％ vs.83.7％, x2 =6.914 and 4.354, P=0.008 and 0.032).The SOD level was higher and the MDA level was lower in observation group than in control group (both P＜0.001) after treatment.Conclusions Edaravone could improve the symptoms of transient ischemic attack in the elderly, and increase the activity of SOD and reduce MDA level, which is helpful to reduce lipid peroxides, alleviate free radical toxicity, and improve the anti-oxidation ability.

An 70-year-old male come for swallowing pain 5 years, turning worse 10 months. Laryngoscopy showed a tumor with rough surface at the laryngeal surface of epiglottic. Outpatient pathology: poorly differentiated carcinoma of the larynx. CT: the root of epiglottic is slightly thickened. He accepted the partial laryngectomy, tracheotomy, bilateral functional neck dissection. Pathology: atypical carcinoid of larynx.

Objective To investigate the characteristics of HBsAg and HBcAg in combination pulsed monocyte-derived DCs(MoDC) derived from patients with HBV-associated hepatocellular carcinoma(HCC).Methods MoDCs were generated from 20 HBV-associated HCC patients,and pulsed with recombinant human serum albumin(rHSA)as conDC(control DC),or pulsed with HBsAg andHBcAg in combination as scDC.Phenotypic patterns of MoDCs were characterized by flow cytometry,and the levels of cytokines releasedby MoDCs were analyzed by ELISA,and frequencies of IFN-γ-producing antigen-specific autologous T cells were measured by Elispotassay.HBV-specific CD8 T cells proliferation was determined by pentamer staining.Results 1.The levels of MHC and costimulatorymolecules expressed on scDC were significantly higher than those on immature MoDC(imaDC)in two groups,and the levels of MHC andcostimulatory molecules expressed on imaDC,conDC and scDC in HBsAg+,anti-HBe+,anti-HBc+patients(1-4-5 positive group)were significantly higher than those in HBsAg+,anti-HBc+patients(1-5 positive group);2.The levels of IL-12 and IL-10 produced byscDC were higher than those produced by imaDC and conDC in both groups,and the levels of IL-12 produced by imaDC,conDC and scDCin 1-4-5 positive group were higher than those in 1-5 positive group.3.The frequencies of IFN-γ-producing T cells induced by scDC werehigher than those by conDC in 1-4-5 positive group.4.scDCs from 4 cases of HLA-A2+patients in 1-4-5 positive group could induceautologous T cells to generate HBVcore18-27-specific CD8 T cells.Condusions HBsAg and HBcAg pulse in combination couldsubstantially reverse the impaired function of MoDCs in HBv-associated HCC patients,and boost MoDC to induce HBV-specific T cellsresponse,especially in HBsAg+,anti-HBe+ and anti-HBe+ patients.

Background The biomeasurement and imageology of retinal nerve fiber layer(RNFL) thickness showed the damage of retinal structure in the early and middle stage of glaucomatous eye,however,the subtle functional damage of glaucoma can not be timely reflected only with automatic static perimeter.Microperimetry is a method of quantitatively assessing mean sensitivity (MS) of macular zone.Objective This study was to evaluate and compare the macular functional change in early and middle stage of primary open angle glaucoma (POAG) and chronic angle-closure glaucoma (CACG) with MP-1 microperimeter.Metbods This trail protocol was approved by Ethic Committee of Peiking University Third Hospital,and written informed consent was obtained from each subject prior to entering the study group.A cross-sectional and case-controlled study was designed.A total of 126 eyes from 126 subjects were enrolled in the trail,including 53 eyes of 53 normal subjects,50 eyes of POAG patients and 23 eyes of CACG patients.A macular 10° program was set with MP-1 microperimetry to record the MS of various subareas.The macula was zoned into central 2°,6°,and 10° visual fields and 4 quadrants in each ring.The MS of different rings and subareas was detected and compared among POAG patients,CACG patients and normal controls.Results The MS values of central 2°,6°,10° and whole macular area were (15.09 ± 3.03),(15.72 ± 3.22),(13.99 ± 3.63) and (14.91±3.07)dB in the POAG group,which were significantly lower than those of (17.29±1.59),(18.05±1.24),(16.76±1.89) and (17.37±1.46)dB in the normal control group (all at P=0.000).The MS values of central 2°,6°,10° and whole macular area was (16.00±2.39),(15.83±2.63),(14.45±3.15) and (15.42±2.54) dB in the CACG group,and the reduced MSs were seen at the 6°,10° rings and whole macular area in the CACG group compared with the normal control group (P =0.004,0.013,0.011).Within the 6° ring,the MS values in the inferotemporal quadrant were declined in the POAG group and CACG group compared with the normal control group (P =0.000,0.022),but the difference was not statistically significant between the POAG group and the CACG group (P =0.311).In addition,the MS value in the inferonasal quadrant was significantly lower than that of the normal control group (P =0.005); while that in the CACG group was not significantly different in comparison with the normal control group (P=0.119).In the POAG group,the MS value of the inferotemporal quadrant was significantly lower than that of the superonasal or superotemopral quadrant (P =0.043,0.016),but no significant differences were found among the 4 quadrants in the CACG group (all at P＞0.05).Conclusions The mild damage of retinal function appears in the early and middle stage of POAG and CACG.More serious MS reducing occurs in the inferotemporal and inferonasal quadrants of POAG.
