[Effects of Rb1 and Rg1 on the expression of Bcl-2, Bax in apoptosis of HK-2 cells induced by the serum of kidney ischemia/reperfusion].

Aim: To explore effects of Ginsenosides (Rb1, Rg1) on the expression of Bcl-2, Bax in the serum of kidney ischemia/reperfusion inducing apoptosis of HK-2 cells.

Methods: The serum of rabbits with renal ischemia/reperfusion (SIR) and the control serum of rabbits (SC) were acquired and cultured with HK-2 cells. Detected apoptosis with TUNEL assay.

[Genetic polymorphism analysis of 8 short tandem repeat loci on the X chromosome in Luoba population of China].

Objective: To investigate the alleles and genotype frequency of 8 short tandem repeat (STR) loci (DXS6804, DXS8378, DXS7132, DXS7133, DXS6789, DXS101, HPRTB and DXS7423) on the X chromosome in Luoba ethnic group of China.

Methods: The eight X chromosome STR (X-STR) loci were analyzed by polymerase chain reaction (PCR) followed by polyacylamide gel electrophoresis and silver stain.

Results: Among 96 unrelated Luoba individuals, the numbers of alleles in the 8 X-STR loci (DXS7133, DXS6789, DXS6804, DXS8378, DXS101, DXS7424, DXS7132 and HPRTB) were 5, 8, 7, 5, 8, 8, 8 and 5, respectively.

[Changes of the content of Se and the levels of several cytokines in the serum of patients with Kaschin-Beck disease].

Aim: To investigate the levels of selenium (Se) and several cytokines (TNF-alpha, VEGF and IL-1beta) in the serum of patients with Kaschin-Beck disease (KBD).

Methods: 90 subjects were selected, from KBD areas and non-KBD areas of Lhasa, Tibet. Then they were divided into 3 groups: the group with KBD (30), the control in KBD areas (30), and the control in non-KBD areas (30).
