To improve the quality of clinical practice education,questionnaires were distributed to the medical interns. Corresponding responses were proposed based on humanities quality,quality of clinical practice and its factors,views on after-department examination and training for clinical skill. The result shows most of students realized the importance of clinical practice. After reformation for clinical education,after-department examination could efficiently improve interns’ability to resolve practical problems. Management of teachers,development of students’clinical thinking and ability of communication between doctor and patient should be enhanced .

Objective:To perform trans-peritoneal laparoscopic adrenalectomy via a single incision in treatment of adrenal tumors,and to discuss its clinical outcome and safety.Methods:Single incision trans-peritoneal laparoscopic adrenalectomy was used in treatment of three patients with adrenal tumors.The incision was made 3 cm below the costal margin of anterior axillary line; three Tocars were placed in the cut.The instruments used included single port access,CUSA,Hem-o-lok,etc..Results:The three operations were all successful,and there were no conversion to open procedure or a need for extra Ttrocars.The operating time periods were 75,116,and 135 min,with a mean of (108.7?30.7)min.The perioperative blood losses were 10,20,and 30 ml,with a mean of (20?10)ml.The gastric canal and ureteral catheter were withdrew one day after operation,and the drainage tube was withdrew 3 d after operation.The mean postoperative hospital stay was 4 d.Conclusion:Single incision trans-peritoneal laparoscopic adrenalectomy has the advantage of little trauma,less blood loss,satisfactory safety,and prompt postoperative recovery,but is difficult to manage.

ObjectiveTo study the mechanism of Shexiang Tongxin Dripping pills-containing serum (STDP) in ameliorating angiotensinⅡ (AngⅡ)-induced cell phenotype transformation, proliferation, migration, and dysfunction of vascular smooth muscle cells. MethodsAn AngⅡ-induced proliferation and migration model of vascular smooth muscle cells was established. The cells were treated with STDP at 5%, 10%, and 20% for 24 h. The immunofluorescence assay was employed to detect the expression of α smooth muscle actin (α-SMA) and matrix metalloproteinase-2 (MMP-2). The cell-counting kit-8 (CCK-8) assay and 5-ethynyl-2'-deoxyuridine (EdU) staining were employed to detect the proliferation of vascular smooth muscle cells, and the scratch assay was employed to detect the migration of the cells. Western blot was employed to determine the expression levels of pathway proteins such as angiotensin-converting enzyme 2 (ACE2), angiotensin Ⅱ type 2 (AT2), angiotensin Ⅱ type 1 (AT1), as well as proliferation and migration proteins such as typeⅠ collagen (ColⅠ) and osteopontin (OPN). ResultsCompared with the model group, STDP increased the expression of α-SMA, reduced the expression of MMP-2, and inhibited the proliferation and migration of vascular smooth muscle cells (P<0.05). Furthermore, STDP up-regulated the expression levels of ACE2, AT2, and MAS1, while down-regulating the expression level of AT1, PCNA, ColⅠ, MMP-9, Rock1, Rock2, and SRF (P<0.05). Compared with the STDP group, the ACE2 inhibitor reversed the regulatory effects of STDP. ConclusionSTDP inhibits the phenotype transformation, proliferation, and migration of vascular smooth muscle cells and regulates the expression of cell proliferation and migration-related proteins to ameliorate the dysfunction of vascular smooth muscle cells. It exerts the effects by up-regulating the expression of proteins in the ACE2-AT2/MAS pathway and down-regulating the expression of proteins in the AT1-Rock signaling pathway.
