[Effect of Huaier Aqueous Extract Combined with Routine Chemo-therapeutic Drugs on Human Acute Lymphoblastic Leukemia Cells Nalm-6 and Sup-B15].

Objective: To investigate the proliferation inhibition and pro-apoptotic effect of Huaier aqueous extract combined with routine chemotherapeutic drugs including Vincristine (VCR), Daunorubicin (DNR), L-aspartase (L-Asp) on human acute lymphoblastic leukemia cell lines Nalm-6 and Sup-B15.

Methods: Nalm-6 and Sup-B15 cell lines were treated with different concentrations of Huaier aqueous extract and chemotherapeutics including VCR, DNR, L-Asp alone or in combination for 48 h, and the growth inhibitory effect and IC values (the half maximal inhibitory concentration) were detected by CCK-8. Jin's formula was used to estimated the synergistic effect of these combinations.

[Pure red cell aplasia in children: a clinical analysis of 16 cases].

Objective: To study the clinical features, treatment, and prognosis of pure red cell aplasia (PRCA) in children.

Health inequalities during 20 years of rapid economic development in China (1980-2000): a mortality analysis.

Objective: To examine the influence of China's economic reforms on population health and regional mortality rates.

Methods: Longitudinal study measuring the mortality trends and their regional variations. Using data from the three most recent national censuses, we used the model life table to adjust the mortality levels within the population for each census, and to calculate life expectancy.
