Objective To study the effect of three different kinds of intervenient measures for TB control on the disease burden of TB patients. Method The estimating method of disability adjusted life years(DALY) as recommended by the WHO was used to assess the disease burden of TB patients. Result The average disease burden of new and retreated TB patients covered by the international TB program(ITP) was the lightest, with the loss of 0.31 DALY and 0.62 DALY respectively; the average disease burden of new and retreated TB patients covered by the national TB program(NTP) was intermediate, with the loss of 0.42 DALY and 0.59 DALY respectively; and the average disease burden of new and retreated TB patients from areas using conventional TB therapy(CTT) was the heaviest, with the loss of 0.61 DALY and 0.91 DALY respectively. From a social perspective, the average yearly loss of DALY per thousand TB patients in the ITP, NTP and CTT areas was respectively 16.42, 33.6 and 37.36, with the loss in the NTP areas being 2.05 times as much as that in the ITP areas and the loss in the CTT areas being 2.28 times as much as that in the NTP areas. Conclusion ITP was far superior to NTP and CTT in reducing the disease burden of TB patients, achieving better results both from the perspective of TB patients and the society.

Objective To study the effect of different intervenient measures for TB control on disease financial burden. Method A survey was conducted of the expenses incurred on 1 700 new and retreated TB patients from areas covered by the World Bank project, the Ministry of Public Health project, and non project areas where intervenient measures were also taken. The method of economic estimation was used to explore the disease financial burden carried by the patients families and society. Result The average family disease financial burden is as follows: 1 735 yuan for a new case and 2 755.99 yuan for a retreated case in the international TB program(ITP); 2 669.27 yuan for a new case and 3 530.17 yuan for a retreated case in the national TB program(NTP); and 6 787.02 yuan for a new case and 7 276.10 yuan for a retreated case in the non project areas using conventional TB therapy(CTT). The average social disease financial burden is as follows: 4 735.55 yuan in ITP; 6 471.91 yuan in NTP; and 10 919.96 yuan in CTT. Conclusion The disease financial burden was the lowest in ITP, highest in CTT, and intermediate in NTP.

After the stratification of the normal glucose tolerance, the changes of insulin resistance and βcell function in the development of type 2 diabetes mellitus were investigated. A retrospective analysis on data of 275 cases with oral glucose insulin releasing tests. The area under the insulin curve (AUCINS ) 108. 43 mU/ L was taken as the critical value of diagnosis. Normal glucose tolerance subjects were divided into the NGT-a group(AUCINS<108. 43 mU/ L) and the NGT-b group(AUCINS≥108. 43 mU/ L). The plasma glucose, insulin, insulin sensitivity, and β cell function were compared among the 4 groups: NGT-a group (n=96), NGT-b group (n=49), prediabetes group (n=71), and type 2 diabetes mellitus group ( n = 59). Among the fasting insulin, 2 h insulin, AUCINS , early-phase insulin secretion index(△I30 / △G30), the ratio of total insulin area under curve, and total glucose area under curve, disposition index, homeostasis model assessment for insulin resistance, and Matsuda insulin sensitivity index, the relationship as follows: NGT-b group>prediabetes group>NGT-a group>type 2 diabetes mellitus group. The NGT-b group was always the highest, prediabetes group was lower, NGT-a group and type 2 diabetes mellitus group were the lowest, there were significant differences (all P<0. 05). Making the NGT-a group as the basic state, in the NGT-b group, β cell function has begun to appear compensation and insulin resistance, and β cell function compensation reached the peak, the β cell function in the prediabetes group was beginning to compensate for the deficiency, the function of β cell in type 2 diabetes mellitus group decreased further. These findings suggest that the development process of type 2 diabetes mellitus could be the following four stages according to the function of β cell: β cell function normal, β cell functional compensation, β cell function loss of compensation, and finally β cell function failure.
