Objective To investigate the effect of recent blood glucose control level of diabetes on prognosis in the patients with general surgery. Methods To analyze the clinical data of 126 diabetic patients with general surgery and the relatiouship among the average hospitalized length,medical cost and the complications of sugery due to glycosylated hemoglobin. Results Comparing with controls, diabetic patients HbA1c＞7.5% had more days longer than those HbA1c＜6.5 % at the time of average in-hospital duration, stitch removing, food-taking and using antibiotics after the operation,Diabetics HbA1c＜6.5 % with cholecystolithiasis, thyroid adenoma had lower surgery cost than those HbA1c＞7.5 %. Conclusion To intensify the control of blood glucose of the patients of limited or selective general surgery as to lower glycosylated hemoglobin＜6.5 % is very important for improving prognosis, and decreasing the complications and medical cost of the operation.

Objective To investigate the characteristic of type 2 diabetes (T2DM) patients with coronary heart disease (CHD),and provide methods for prevention and treatment for patients who suffered from CHD.Methods The hospitalized patients were divided into three groups.The treatment group contains 46 cases who were T2D with CHD;The control group Ⅰ contains 30 cases who were T2DM without CHD;The control group Ⅱ contains 50 cases who were CHD without T2DM.Their ordinary circumstances were compared;the blood sugar,BP,TC,TG,HDL,LDL,HbA1c,C-P,Ins were measured.Insulin sensitive index(ISI) was calculated.Results Three groups had obvious statistical differences in BP,TC,LDL-C,ISI,HbA1 c.Diabetic patients with CHD have more common with three lesions.Conclusion In the clinical job,the composite observation should be strengthened and treatment because the factors of atherosclerosis in T2DM patients were numerous and complex.

Objective To investigate and analyze the effect and insulin dosage of insulin pump in type 2 diabetes. Methods 63 hospital patients with type 2 diabetes(FPG≥12mmol/L), who had poorly controlled blood glucose, were treated by insulin pump for 14 days, without hypoglycemic agents. The treatment days when blood glucose was well controlled and the insulin dosage at that time were observed. FPG, CBG, HbA1c, FINS/FPG, ISI, Homa-B and Homa-IR were measured before and after insulin pump. Results When blood glucose were well controlled, the mean time was (5.4+1.6) days, the insulin was (0.6+0.2)U/kg, the basal insulin was 38%. The dosage of insulin was decreased after blood glucose were controlled. Reaction of hypoglycemia was (0.6+0.2). After 2 weeks insulin pump intensive treatment, the result of FPG, CBG, HOMA-IR and HbA1c were significantly decreased (all P<0.01); FINS/FPG, HOMA-B and ISI were incleased (all P<0.01). Conclusion The excellent glycemic control and improvement of beta-cell function can be induced by short-term insulin pump intensive therapy in diagnosed type 2 diabetic patients with severe hypoglycemia.

Objective To sum up the measures for nursing the patients with laparoscopic gastrectomy-induced anastomotic leakage treated by open center vacuum aspiration. Method We retrospectively reviewed the histories of 22 patients with laparoscopic gastrectomy-induced anastomotic leakage to look into the nursing measures to look into the management of open vacuum aspiration , observation of the drainage, leakage care, mental care. Results The time for open center vacuum aspiration was between 10 to 17 days, averaged (15.63 ± 3.22)d. The hospital stay was between 13 to 23 days, averaged (17.21 ± 5.47)d. No complications were observed. Conclusions The nursing measures for managing the anastomotic leakage can be effective in improving the effect of peritoneal irrigation. The mental care can be effective for the reduction of patients′pains so as to promote the heal of the leakages.

Aim Tostudytheeffectsofferulicacid (FA) on doxorubicin (DOX) induced cellular injury inH9c2ratmyocardialcells.Methods H9c2cells were treated with 1μmol·L-1 DOX treated for 24 h to establish a myocardial injury model. 10, 20, 40μmol ·L-1 FA was added 2 h before DOX treatment. Cell viability was measured by cell counter kit ( CCK-8 ) . Morphological changes were observed by phase contrast microscope. LDH, CK, MDA, SOD levels were detec-ted by biochemical kits. Intracellular level of reactive oxygen species ( ROS) was examined by DCF-DA stai-ning with flow cytometry. Cellular apoptosis was detec-ted by AO-EB staining and DNA agarose gel electro-phoresis. The expression of caspase-3, Bax, Bcl-2 was evaluatedbyWesternblot.Results Exposureof H9c2 cells to DOX led to decrease in cell viability, in-crease in stress and apoptosis. FA pre-treatment im-proved cell viability in a dose-dependent manner, at-tenuated leakage of LDH and CK, and reversed mor-phological changes induced by DOX. FA suppressed DOX-induced oxidative stress as evidenced by reducing ROS and MDA generation and increasing SOD enzyme activity. FA depressed myocardial apoptosis by down-regulating pro-apoptotic protein caspase-3 and Bax, whereas up-regulating apoptosis inhibitory protein Bcl-2.Conclusions FAhasaprotectiveeffectonDOX-induced injury in H9c2 cells. This protection may re-sult from inhibition of myocardial oxidative stress and apoptosis.

BACKGROUND:Endothelial progenitor cells are recruited into local vascular injury under the injury-induced stimulation, and then differentiate into mature endothelial cells that are thereby involved in angiogenesis and endothelial repair. OBJECTIVE:To investigate whether endothelial progenitor cells can al eviate renal injury and improve renal function of ischemia/reperfusion injury (I/R) rats. METHODS:Peripheral blood samples extracted from Sprague-Dawley rats were used to isolate and culture endothelial progenitor cells using density gradient centrifugation. Twenty-two male Sprague-Dawley rats were randomized to three groups:I/R group, normal control group, and endothelial progenitor cells group. In the I/R and endothelial progenitor cells groups, the right kidney was removed and the renal artery and vein of the left kidney were occluded for 40 minutes to establish I/R models in the rats, and then endothelial progenitor cells (5×109/L, total y 1 mL) or solvent was transplanted via the artery of the left kidney into the left kidney. In the normal control group, the experimental procedure was same as that in the I/R group except for occlusion of the artery and vein of the left kidney. Renal and blood samples from three groups were col ected at day 1 after operation. Peripheral blood CD34 and vascular endoethelial growth factor receptor 2 expressions were determined using flow cytometry and immunofluorescence methods, serum creatinine and urea nitrogen were tested, and immunohistochemistry observation was used for CD34 observation. RESULTS AND CONCLUSION:Compared with the normal control group, serum creatinine and urea nitrogen levels were significantly increased, and tubulointerstitial CD34 expression was decreased in the I/R group (P<0.05). Endothelial progenitor cells treatment largely decreased the levels of serum creatinine and urea nitrogen, and increased CD34 expression (P<0.05). These findings indicate that transplantation of endothelial progenitor cells contributes to renal protection in I/R rats.
