AIM: To study the effect of natural killer(NK)-cells on graft-versus-host disease(GVHD), graft rejection, engraftment and reconstituting of hematopoiesis in mouse allogeneic bone marrow transplantation. METHODS: Lethally irradiated BALB/c(H-2 d) mice were transplanted with C57/6j(H-2 b) bone marrow containing donor peripheral T cells and/or NK cells. Recipients CD 34 + cell counts and the expression of H-2K b+ cell were detected by flow cytometry, peripheral white blood cell(WBC) was detected by auto-cytometry, and the recipients survival rates, GVHD, engraftment and hematopoiesis recovery were then observed. RESULTS: In the group of transplanted with NK cells infusion, the incidence of GVHD was evidently lessened, the survival rates, WBC and CD 34 + cell counts and the expression of H-2K b+ cell were significantly high than that without NK cells infusion. CONCLUSION: In mouse allogeneic bone marrow transplantation, alloreactivity NK cells prevent GVHD, reduce graft rejection, and promote engraftment and reconstituting of hematopoiesis. [

A high performance liquid chromatography-tandem mass spectrometric( HPLC-MS/MS) method was developed for the simultaneous determination of four phenolic and salicylanilide anthelmintics including nitroxinil, oxyclozanide, closantel and rafoxanide in cattle and ovine tissues. Muscle, liverand kidney were extracted with acetonitrile-acetone(60:40, V/V)and fat with 1% triethylamine in acetonitrile, then the extract was purified with MAX solid-phase extraction column. Qualitative and quantitative analysiswas achieved by HPLC-MS/MS undernegative multiple reaction monitoring ( MRM) mode. Good correlation coefficients were obtained (R>0. 99) in the concentration range of 1-100 μg/L. The limits of detection (LOD) and limits of qualification (LOQ) for the four compounds were 1 and 2. 5 μg/kg, respectively. The mean recoveries at the four levels of LOQ, 0. 5 maximum residue limit (MRL), MRL, 2MRL were between 71% and 112%,with the intra-day relative standard deviation(RSD)in the range of 1. 1%-14. 0%and inter-day RSD in the range of 6. 4%-14. 7%. Forty samples from the market were analyzed with the method, only two samples were found to show phenolic and salicylanilide anthelmintics residues.

Objective To observe the impatcts of health care follow-up after chronic heart failture on cardiovascular events and qualigy of life.Methods One hundred and sixty-six patients who were confirmed to have chronic heart failture in our hospital during February 2007 and December 2008 were enrolled in this investigation.The patients were then assigned to the health management group (n=65) or the non-health management group (n=101) and followed up for 5 years.All-cause mortality,readmission for heart failture and quality of life (SF-36 score) were evaluated.Results There was no significant difference of all-cause mortalitv between the two groups (health management group:12.30％ (8/65); non-health management group:14.85％ (15/101; x2=0.22,P＞0.05),although a statistically significant difference of readmission rate was found between the two groups (health management group:12.30％ (9/65); non-health management group:35.64％ (36/101; x2=9.51,P＜0.05).In health management group,the scores of SF-36 were significantly increased at 3 (114.11 ±2.76) or 5 years (116.07± 15.43) when compared with baseline (91.37 ± 2.62) (x2 =102.39,P＜0.05).For the non-health management group,the scores of SF-36 were significantly decreased from 92.65±3.65 at baseline to 90.09±5.12 at 3 years or 89.08±5.71 at 5 years (x2=102.39,P＜0.05).Conclusion Health care follow-up after chronic heart failture may not decrease all-cause mortality,although can decrease readmission rate and improve quality of life of the patients.

AIM: To investigate the effects of uric acid sodium salt (UANa) as adjuvant on humoral and cellular immune response in BALB/c mice. METHODS: BALB/c mice were immunized with trichosanthin (TCS) as antigen together with UANa suspension as adjuvant. The antibody titers of IgG were detected by enzyme-linked immunosorbent assay. Dendritic cells (DC) were induced in vitro, the phenotypes of DC were analyzed by flow cytometry and the effect of UANa on DC maturity was evaluated. A delayed-type hypersensitivity (DTH) model was used to analyze the effect of UANa on cellular immune responses in vivo. The in vitro proliferation of lymphocytes was determined by ConA stimulation. RESULTS: Freunds adjuvant greatly enhanced the antibody response of mice to TCS, while UANa adjuvant failed to promote the antibody response but significantly reduced the antibody response as compared to TCS only. No effect of UANa on the expression of CD11c and CD83 in DC was observed by flow cytometry analysis. However, UANa significantly enhanced the expression of MHC II molecule. In the DTH model, UANa enhanced the degree of allergen-induced ear swelling and promoted the ability of lymphocyte proliferation in vitro. CONCLUSION: UANa suspension as adjuvant significantly enhances the cellular immune response but inhibits the humoral immune response to a certain degree, suggesting that UANa has potential application in the vaccine research.

AIM: To investigate the inhibitory effect of quercetin on in vitro activation of T lymphocytes by polyclonal activators with CD69 expression as an activation marker. METHODS: After being separated from lymphoid nodes of a C57BL/6 mouse, the lymphocytes were exposed to polyclonal activators (PDB or Con A) with or without quercetin. Then they were harvested at 2 h, 6 h and 24 h, respectively. The expressional rates of CD69 on T lymphocytes were assessed by two-color immunofluorescent staining and flow cytometry, and the inhibitory rates of quercetin at different time points were estimated. RESULTS: Quercetin had no effect on the expressional rate of CD69 on T lymphocytes under resting states. After the stimulation with PDB or Con A, the expressional rates of CD69 on T lymphocytes in the present of quercetin (10 ?mol/L) showed significant decrease compared with those of control groups at different time points (P

Objective To observe and contrast the effects of dexmedetomidine and ketamine on the restlessness and analgesia during recovery period of anesthesia after tonsillectomy in children. Methods Sixty ASA Ⅰ-Ⅱ child patients underwent tonsillectomy and adenoidectomy were randomly divided into three groups, group P (appropriate amount of placebo was given in the operation), group D (dexmedetomidine) and group K (ketamine). Data of mean arterial pressure and heart rate of three groups were documented before anesthesia (T0), during extubation (T1), 5 min (T2), 10 min (T3), 15 min (T4) and 30 min (T5) after extubation were recorded. The analepsia time, adverse reactions, restlessness score and pain score were collected in three groups of patients. Results Compared with group P, values of mean arterial pressure and heart rate were more stable at T1, T2 and T3 in groups D and K (P<0.05). The restlessness score, incidence of restlessness and adverse reactions were lower in groups D and K than those in group P (P<0.05), and which were lower in group D than those of group K (P<0.05). Conclusion Both dexmedetomidine and ketamine can play an analgesic role in recovery period of anesthesia and reduce restlessness, adverse reactions and pain score in child patients. Moreover, dexmedetomidine is more effective on inhibiting restlessness and adverse reactions.
