Objective:To identify the contributions of allergen to Th1 and Th2 by determined the levels of IFN-?,IL-4 and the transcription factors T-bet and GATA-3 in peripheral blood mononuclear cells(PBMC)of allergic asthmatics.Methods:①Plasma IFN-? and IL-4 were measured in 35 asthmatics and 32 healthy by ELISA,as well as the production of IFN-? and IL-4 by Dermatophagoides farinae(Df)-activated PBMC in asthmatics and 15 healthy controls.②Twenty-five asthmatics and 15 healthy persons were enrolled.The T-bet mRNA and GATA-3 mRNA expressing levels in PBMC were assayed by one step reverse transcription polymerase chain reaction(RT-PCR).Results:①The plasma IL-4 in the patients was significantly higher than that in healthy(t=3.265 9,P=0.001 7).The plasma IFN-? levels in asthmatics were no significantly different from that of the healthy(t=0.306 8,P=0.760 0).② In the condition of PBMCs activated by Df,the IL-4 and IFN-? levels in asthmatics were increased compared with healthy(t=3.564 4,P=0.001 0;t=3.350 0,P=0.002 0).③ There were some expression of the transcription factors T-bet and GATA-3 of PBMC in asthmatics and healthy.The expression of GATA-3 in the patients was significantly higher than that in healthy(t=2.274 3,P=0.028 0).The expression of T-bet and the ratio of T-bet/GATA-3 in the patients was no significant difference with the healthy(t=0.222 0,P=0.825 8;t=1.115 2,P=0.283 4).④ In the Df-activated PBMC,the expression of T-bet and GATA-3 in asthmatics were significantly higher than that of healthy(t=2.298 2,P=0.027 6;t=3.788 7,P=0.000 6),but the ratio of T-bet/GATA-3 was no significant difference with healthy(t=1.195 9,P=0.249 1).Conclusion:The production of Th2,Th1 cytokines and the expression of GATA-3 and T-bet in allergic asthmatics are both increased.It is suggested that the imbanlance of Th1/Th2 unsatisfactorily explain the pathogenesis of allergic asthma.

The soybean high branched-chain amino acid mixture was composed of soybean protein hydrolyzed by special method with a few types additional amino acids in small amount. The mixture contained 68.9% of essential ami-no acids and 42.9% of branched-chain amino acids.The animal experiment showed that the mixture could promote the growth of young rats and maintain the normal levels of Hb, serum total protein and albumin. Its protein efficiency ratio (PER), true protein digestibility (TD), biological value (BV) and net protein utilization (NPU) were 2.78, 94.0%, 85.0 and 80.0% respectively. These values were significantly higher than that of casein. The results indicated that the soybean high branched-chain amio acid mixture did not produce amino acid antagonism caused by the high amount of branched-chain amino acids and had higher nutritional quality.

Objective To evaluate the effect of the expression of P-glycoprotein (P-gp) in tumor tissue on analgesic efficacy of morphine and buprenorphine in advanced cancer patients with pain. Methods One hundred and fifty advanced cancer patients with pain aged 51-64 yr weighing 54-65 kg were included in this study. The expression of P-gp was negative in the tumor tissue in 50 patients (group M1 and B1, n = 25 each) and positive in 100 patients (group M2 ,M3 ,and B2 ,B3, n =25 each). The PCA regimen for the 6 groups were listed in the table .Pain was assessed with VAS scores (0 = no pain, 10 = worst pain) and venous blood samples were taken for determination of blood morphine/buprenorphine concentrations at 4, 12, 24 and 48 h of PCIA. Results The six groups were comparable with respect to age, body weight, M/F sex ratio, types of cancer, baseline pain level and education. The analgesic efficacy of morphine and buprenorphine was better ( VAS scores were significantly lower)in P-gp expression negative patients (group M1 and B1 ) than in P-gp expression positive patients (group M2 and B2 ). Higher doses of morphine and buprenorphine provided better analgesic efficacy in P-gp expression positive patients in group M3 and B3 than in group M2 and B2. Plasma morphine and buprenorphine concentrations were comparable between group M1 , B1 and M2, B2 and were significantly higher in group M3 and B3 at each time point. Conclusion Positive P-gp expression in the tumor tissue can decrease the analgesic efficacy of morphine and buprenorphine in advanced cancer patients with pain.

Purpose:To investigate the value of susceptibility-weighted imaging(SWI)in evaluating the histopathologic grade of cerebral astrocytomas.Materials and Methods: 18 patients with histologically proven cerebral astrocytomas,including 7 diffuse astrocytomas,3 ana-plastic astrocytomas and 8 glioblastomas before treatment were involved in this study.The features on SWI were analyzed in 18 cerebral astrocytomas.Results: The veins in the tumors were not detected in 7 diffuse astrocytomas.Slight edema round tumors appeared in all the diffuse astrocytomas.Plenty veins in the tumors and severe edema round the tumors appeared in 3 anaplastic astrocytomas and 8 glioblastomas.The hemorrhagic foci were detected in 1 anaplastic astrocytomas and 6 glioblastomas.The edema round the tumors were moderate or severe in all the anaplastic astrocytomas or glioblastomas.Conclusions: Susceptibility-weighted imaging can provide the informations about blood supply,hemorrhagic focus and edema round the tumors.SWI is very useful for preoperative evaluation of the histopathologic grade of cerebral astrocytomas,especially for evaluation of high or low grade astrocytomas.

OBJECTIVE To discuss the liable episodes of the urinary tract infection with relation of catheter and propose the prevention measures.METHODS We radomly selected 536 patients with catheter.The urinary tract infection,as well as related factors were observed in patients with indwelling catheter.RESULTS The catheter replacement time interval as well as indwelling time were the risk factors,when the indwelling catheter time was 1-3 days,the CAUTI rate was 10.3%,if the time was ≥10 day,the CAUTI rate was 97.6%.Additionally the antibiotic use would cause dysbacteriosis which also easily caused the urinary tract road infection.CONCLUSIONS When taking care of the patients who had catheter,we should grasp the indications of catheterization,reduce the indwelling time,apply the effective nursing measures and correct choice of antibiotics,that can evidently control the infection.

This article was aimed to study the immunomodulatory effect of ethanol sediments of the seeds of Descurainia sophia(L.) Webb. ex Prantl. both in vitro and in vivo. The lymphocyte proliferation test in vitro was carried out to explore the effect of the ethanol sediments on the proliferation of T cell and B cell in the spleen of normal mice. And, the carbon clearance test, serum hemolysin test, and delayed-type hypersensitivity test were used to investigate the influence of fraction on non-specific immunity, humoral immunity and cellular immunity in the immunosuppressive mice induced by cyclophosphamide. Besides, the immunosuppressive model was used to evaluate the effect of fraction on immune organs and content of cellular factors in blood serum. The results showed that the ethanol sediments promoted Concanavalin A (Con A) induced T cell and Lipopolysaccharides (LPS) induced B cell (P < 0.01). It increased the carbon clearance index K, phagocytic index α, half value hemolysis (HC50), and swelling degree of auricula (P < 0.05 or P < 0.01). It reduced the body weight and atrophy of thymus and spleen index (P < 0.05 or P < 0.01). It increased the contents of IL-2, IFN-γ and IL-4 in serum in immunosuppressive mice (P < 0.05 or P < 0.01). It was concluded that ethanol sediments of the seeds of D. sophia(L.) Webb. ex Prantl. can boost the lymphocyte proliferation, protect the immune organs, and enhance the non-specific and specific immunity in immunosuppressive mice, which indicated that it had immune-promotion effect.
