Results from the output-oriented BCC model show that Treatment 4 ( 600 mg of zidovudine plus 400 mg of didanosine plus 400 mg of nevirapine) is particularly efficient for age group 14—25, but not efficient for the older age groups; Treatment 1 (600 mg of zidovudine alternating monthly with 400 mg of didanosine)and Treatment 2 (600 mg of zidovudine plus 2.25 mg of zalcitabine) are efficient for the age groups 35—45 and 45— ; age group 25—35 does not have a particularly efficient treatment, but Treatments 1 and 2 are relatively good. The cost efficiency BCC model, which takes the treatment cost into account, gives similar results as the output-oriented model. Results from the indirect output-oriented BCC model, which allows the replacement among medicines, show that the efficiency of Treatment 2 has greatly decreased compared with that of the output-oriented model, and a set of optimal medicine amounts for different age groups is obtained.展开更多

Methods: A multicenter medical effectiveness trial conducte d in 10 hospitals of 5 regions in Zhejiang Province. 248 patient-volunteers were ass ig ned to 8 weeks of ″ triple combination therapy″ with Lansoprazole plus Cisapri de and Sucralfate or Ranitidine plus Cisapride and Sucralfate. Main outcomes asses sment included symptoms scale scores,RE severity,QoL at baseline and 8 weeks. Medical cost data were collected with cost analysis questionnaire. Results: (1)M ore Lansoprazole group patients noted RE symptoms resolution than Ranitidine gro up(92.3% vs 78.4%,P<0.01). There was no striking difference between two gro ups in RE healing rate (90.8% vs 82.9%, P>0.05). (2)RE significantly impaire d QoL of patients(P<0.001).Compared with Ranitidine group,QoL in Lansoprazole group had significant improvement (rate of ″good″ QoL 64.5% vs 45.6%,P<0.01). (3)T here w as close correlation between symptomic effectiveness and QoL rating scale in bot h the Lansoprazole and Ranitidine group(P<0.01,r=0.235 and 0.353 respec tively). There were no statistical difference of medical cost between the two groups ( P> 0.05). Conclusion: RE significantly impaired QoL of patients. ″Triple combinati o n therapies″ can significantly improve RE symptoms and QoL. Lansoprazole combin ation therapy was more cost-effective than Ranitidine combination group.展开更多

But the study on engineering application is less common. There is a lack of corresponding research results about equipment, process and treatment effect. According to the above problems, this paper discusses the treatment process combining with sludge solidification/stabilization landfill field in Fuyong Town in Shenzhen City. Furthermore, the strength, moisture content, environmental indexes of treated sludge in field test was carried out in order to monitor the treatment effect. The results showed that the sludge solidification/stabilization equipment can meet the need of large-scale engineering application and the treatment process is relatively simple and the solidified sludge can meet the need of landfill.展开更多

The therapeutic benefits of Aloe gel could be extended to food products concomitantly improving its acceptability. Dahi/curd is an Asian fermented dairy product that enjoys tremendous mass appeal. The objective of the present study was to formulate dahi enriched with Aloe gel (AG) as a functional ingredient and to study its effect on the quality of dahi. Plain dahi was prepared by addition of 2.5% skimmed milk powder (SMP) and suitable starter to milk. For the preparation of AG enriched dahi, SMP was replaced by AG at different levels (0.1-0.25%). The products were evaluated for moisture, pH, titrable acidity (TA), whey syneresis (WS), total solid content (TS), water holding capacity (WHC), total yield (TY), whiteness index (WI), and viscosity. Microbial analysis and sensory evaluation were also carried out. Enrichment of dahi with AG was found to improve its quality characteristics by causing a significant reduction in WS and an increase in TA, TS, WHC, TY, WI and viscosity. AG dahi recorded good sensory acceptability. Storage study also indicated AG dahi to perform better in terms of the various parameters studied. The present investigation suggests the feasibility of adding Aloe gel powder as a functional ingredient to dahi to enhance product quality as well as its nutritional and therapeutic potency. It could be commercially exploited as a novel product.展开更多

Importantly, this progress has been achieved, not by the induction of immunity, but by the delivery of immunity in the form of engineered antibodies (cAbs) or effector T cells. However, these single-target technologies have failed to result in a therapeutic effect in some patients, and evidence suggests that further advances depend on an effective strategy for coping with cancer heterogeneity and dynamics. A synthetic immunity (SI) strategy is proposed to achieve this goal. The fundamental basis of SI involves the generation of a panel of cAbs and antibody-retargeted CTLs designed to destroy all cell lineages of a cancer with high specificity. This goal can be achieved only when the composition of the cAbs is determined using a systematic approach, i.e., selecting the antigens targeted by the cAbs based on an epitope-tree illustrating the clonal antigen architecture of the cancer. Integration of technologies that increase the epitope breadth, cAb affinity and T cell activity will further enhance the efficacy of SI. Using DNA vectors to express the eAbs will be a safe, effective and affordable solution.展开更多
