RÉSUMÉ

The present study aimed to investigate the effect of proto-oncogene c-src on the viability of rat spermatogonial stem cells from 9 day-old rat in vitro. MTT method was used to observe the viability of the spermatogonial stem cells treated with antisense c-src oligodeoxynucleotides (ODNs) in vitro; RT-PCR was utilized to observe the expression of c-src mRNA and Western blot was used to observe the protein expressions of pp60c-src and phosphorylated signal transducer and activator of transcription-3 (p-STAT3). Compared with that in control group, the viability of spermatogonial stem cells decreased by 8.1% (P<0.05) and the expression of c-src mRNA decreased significantly after treatment with 10 μmol/L antisense c-src ODNs for 12 h. Compared with that in the control group, the protein expressions of pp60c-src and p-STAT3 decreased by 33.8% and 45.3% (both P<0.01), respectively, in the spermatogonial stem cells after being transfected with antisense c-src ODNs. The results suggest that proto-oncogene c-src regulates the viability of rat spermatogonial stem cells through p-STAT3.

RÉSUMÉ

<p><b>OBJECTIVE</b>To observe the effect of TCM therapy for detoxification, removing stasis, and nourishing yin on corticosteroid-induced hyperlipemia in patients with systemic lupus erythematosus (SLE), and to investigate its mechanism.</p><p><b>METHODS</b>One hundred and seventy patients with SLE were randomly assigned to the integrative medicine group (IM group) and the Western medicine group (WM group), 85 in each group. Also, 30 healthy subjects selected from blood donors were enrolled in the normal control (NC) group. All patients were treated mainly with prednisone, while those in the IM group were given TCM therapy additionally, and the therapeutic course for both groups was 6 successive months. The changes of serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C) and apolipoprotein A (ApoA) were determined and observed. A 2-year follow-up study was carried out in 16 patients of the WM group and 25 of the IM group.</p><p><b>RESULTS</b>Before treatment, no significant difference had been found among the three groups in the serum levels of lipids and lipoproteins. After the 6-month treatment, as compared with the WM group, the IM group showed lower levels of TC, TG, LDL-C, and VLDL-C (P<0.05 or P<0.01) and higher levels of HDL-C and ApoA (P<0.05). A similar effect was also shown by the follow-up study in the IM group (P<0.05 or P<0.01).</p><p><b>CONCLUSION</b>TCM therapy for detoxification, removing stasis, and nourishing yin can effectively regulate the levels of serum lipids and lipoproteins in preventing and treating SLE patients with corticosteroid-induced hyperlipemia.</p>
