ABSTRACT
<p><b>OBJECTIVE</b>To observe the impact of Roux-en-Y gastric bypass on quality of life in non-obese patients with type 2 diabetes mellitus.</p><p><b>METHODS</b>Thirty-seven non-obese patients with type 2 diabetes mellitus who underwent Roux-en-Y gastric bypass were prospectively studied. A 36-item short form healthy survey questionnaire(SF36), the diabetes treatment satisfaction questionnaire(DTSQ), and quality of life scale for patients with type 2 diabetes mellitus(DMQLS) were used to evaluate the quality of life for all the non-obese patients with type 2 diabetes mellitus preoperatively and 12 months postoperatively.</p><p><b>RESULT</b>The blood glucose and lipid indexes were significantly decreased after operation(all P<0.05). SF36 showed the physical and mental synthesis scores at 12 month after operation were 74.6±18.3 and 79.8±14.9 respectively, higher than those at one week before operation(54.9±15.1 and 56.4±17.8, both P<0.01). DTSQ showed treatment satisfaction score was increaced significantly after operation(29.2±7.1 vs. 15.4±5.6, P<0.01). The quality of life evaluated by DMQLS, was also significantly improved(P<0.01).</p><p><b>CONCLUSION</b>Roux-en-Y gastric bypass can significantly improve the quality of life for non-obese patients with type 2 diabetes mellitus.</p>

To investigate the components in Plastrum Testudinis which have effects on the proliferation of rat bone marrow mesenchymal stem cells( bMMSCs), the active parts of plastrum testudinis which can promote proliferation of rat mesenchymal stem cells were extracted by petroleum aether. The activities of inducing the proliferation of bMMSCs were studied by MTT assay and flow cytometry. The chemical components of extraction were analyzed by GC-MS. The results showed that the petroleum aether extraction can obviously promote the proliferation of the stem cells. The main components are long-chain fatty acids, cholesterols and cholest-4-en-3-one, and palmitic acid, stearic acid and cholest-4-en-3-one have effects on proliferation of bMMSCs. In plastrum testudinis, fatty acids can promote the proliferation of bMMSCs but not increase overly. This provide the experiment basis, and offer important reference for Traditional Chinese Medicine that researches stem cells.
