Journal of Medical Postgraduates 2004;0(01):-
Objective:To evaluate the effectiveness of endoscopic minimally invasive treatment for submucosal tumors of the esophagus.Methods:Included in the study were 33 patients with esophageal submucosal tumors,male 23 and female 10 cases,aged 34-85 years(average 51.2).The lesions were removed by means of endoscopic mucosal resection(EMR),or stripping-resection method,i.e.,first stripped by a needle knife and followed by "injection and cut".Results:All the lesions were resected completely by endoscopic minimally invasive methods.Of 33 lesions,15 cases were undertook EMR,and 18 cases were treated by stripping-resection method.Except 5 cases of treatable bleeding,and 6 cases of post-operative substernal pain,no other complications were found.Pathological exam and immunohistochemical study showed that 25 cases were esophageal leiomyoma,3 cases of stromal tumor,2 cases of lipoma,2 cases of haemangioma and 1 case of submucoal cyst.No recurrence was found during the follow-up of 2-30 months. Conclusion:Endoscopic minimally invasive therapy is effective and safe for the treatment of esophageal submucosal tumors.

Objective To investigate the effects of Astragalus polysaccharide (APS) on damage of keratinocytes in ultraviolet B (UVB) radiation skin in HaCaT cells; To preliminarily explore its mechanism of action.Methods HaCaT cells were treated by UVB irradiated for modeling. Blank control group, model group, UVB irradiation group and low-, medium- and high-dose APS interventional groups were set up. Each medication group was given relevant medicine. MTT assay was used to determine the cell activity; GSH-Px, CAT, SOD activity and MDA content were detected by biochemical colorimetric method; contents of TNF-α and IL-6 were detected by ELISA.Results Compared with the control group, the contents of SOD, CAT and GSH-Px in the model group decreased significantly, while the contents of MDA, TNF-α and IL-6 increased significantly (P<0.05); compared with the mode group, the contents of SOD, CAT and GSH-Px in the medication groups increased significantly, while the contents of MDA, TNF-α and IL-6 were reduced significantly (P<0.01).Conclusion APS can reduce the oxidative stress injury of UVB to HaCaT cells to some extent.

Objective To observe the changes of the glycolipid and coronary artery lesions in coronary artery disease patients with isolated post-challenge hyperglycaemia (IPH). Methods Hospitalized coronary artery disease patients diagnosed by coronary angiography were received oral glucose tolerance test. The labarotary test datas, including blood hematochrome, fasting and post-challenge plasma glucose levels, plasma lipid and insulin levels, were recorded. The number of diseased coronary artery and coronary lesion scores were calculated according to coronary angiogram for each patient. Continuous 77 patients with normal glucose metabolism(normal glucose metabolism group) and 104 patients with IPH (IPH group) entered the study. Results The occurrence of hypertension, acute coronary syndrome, multivessel coronary disease, revascularization were 84.6%(88/104), 82.7%(86/104), 69.2%(72/104), 70.2%(73/104) in IPH group and 63.6%(49/77), 70.1%(54/77), 50.6%(39/77), 54.5%(42/77) in normal glucose metabolism group, and there were significant differences(χ2=3.985-10.583, all P<0.05). The body mass index, triglyceride, total cholesterol, fasting glucose, post-challenge glucose, hemoglobin A1c, fasting insulin, insulin resistance index, coronary lesion scores were (27.42±3.55) kg/m2,(2.18±1.53) mmol/L,(4.73 ± 1.00) mmol/L,(5.98 ± 0.92) mmol/L, (14.11 ± 1.94) mmol/L, (5.90 ± 0.78)%, (10.07 ± 6.13) mU/L, 2.617 ± 1.535, (41.35 ± 27.21) points in IPH group and (25.11 ± 3.40) kg/m2, (1.52 ± 0.85) mmol/L, (4.22 ± 1.02) mmol/L, (5.24±0.62) mmol/L, (6.49±1.07) mmol/L, (4.97±0.39)%, (7.72±4.28) mU/L,1.785±0.974, (33.36±23.36) points in normal glucose metabolism group, and there were significant differences(t=3.035-33.698, P<0.05 or 0.01). Conclusions Coronary artery disease patients with IPH have much more seriously abnormal glycolipid metabolism and complex coronary artery lesions, and need specialized nursing management.
