RESUMO

Objective To investigate the methods used for evaluating the severity of the patients with acute pancreatitis induced by hyperlipidemia in order to find out some simple and practical biomarkers for predicting the severity of the illness.Methods Sixty-two patients with acute pancreatitis resulted from hyperlipidemia were selected from the in-patients of our hospital from January 2007 to July 2011 and were divided into two groups,namely the mild acute pancreatitis group(MAP,n =32)and the severe acute pancreatitis group(SAP,n =30)as per the Chinese Acute Pancreatitis Guideline.Two groups were comparable verified by the test of homogeneity of variance after grouping.Arterial blood gas analyses were done immediately after admission:Venous blood was taken from forearm for determining renal function and blood coagulation at 6 o'lock of next day after admission.The data of base excess(BE),creatinine(CR),C-reactive protein(CRP),fibrin(FIB)and D-Dmmer(D-D)were documented.The contrast CT imaging of pancreas was done within 48 hours after admission in all patients.APACHE Ⅱ scores and computed tomography severity index(CTSI)were calculated.The differences in BE,CR,CRP,FIB and D-D between 2 groups were analyzed by using t-test,and the correlation among them and APACHE Ⅱ score and CTSI were analyzed by Spearman test done with SPSS 18.0 software.As BE <-4.5 mnol/L,CR > 120μmol/L,CRP > 100 mg/L,FIB >5.5 g/L and D-D 800 ng/L were set respectively as a positive screening criterion,positive prediction value(PPV),negative prediction value(NPV),sensitivity and specificity of each marker and combined markers were calculated after they were set at different positive scales in order to get the optimal predictors for evaluating the severity of acute pancreatitis induced by hyperlipidemia.Results The absolute values of BE,CR,CRP,FIB and D-D in group SAP were much higher than those in group MAP(P < 0.01).Each of them had good correlation with APACHE Ⅱ score and CTSI,especially BE and D-D more significant.Each of them used separately for predicting the severity of acute pancreatitis showed PPV and NPV with high specificity but the sensitivity was hot high.The joint use of BE,CR and CRP,and joint use of FIB and D-D could be more valid as PPV and NPV with high specificity for predicting the severity of acute pancreatitis,but the sensitivity decreased.Conclusions BE,CR,CRP,FIB and D-D were good biomarkers for quickly and accurately evaluating and predicting the severity of the acute pancreatitis caused by hyperlipidemia.

RESUMO

Objective To treat scalp lacerations by using the hair apposition technique (HAT) and to compare the HAT with standard suturing in a controlled prospective trial. Method Fifty patients with scalp lacerations were treated either by HAT or by standard suturing. Two groups were evaluated in consumed times for operation, pain sores, and complications. Results There were 30 HAT patients and 20 patients treated with suturing. The took shorter operation time consumed[(3.33 vs. (6.05 t = 4.85.P < 0.01], and HAT produced significantly lower pain score [(1.73vs. (3.20t = 4.01,P < 0.01]. There was a trend that more and more patients were willing to have HAT performed. Conclusions The advantages of HAT include a shorter time consumed for operation, less pain, satisfactory wound healing, and high acceptance by patients. HAT is acceptable for treating scalp lacerations in emergency room.

RESUMO

Objective To study the effect of sodium hyaluronate on the expression of transforming growth factor-β3(TGF-β3) and Smad 6 of the epidural scar tissue. Method Totally 60 male SD rats were randomly divided into two groups:the control group(A, n = 30), sodium hyaluronate group(B, n = 30). 0.25 × 1 cm2 dura mater uncovered area laminectomy was performed at L4 and L5, covered with 0.3 ml sodium hyaluronate in group B, covered with same amount of saline in group A. The animals were sacrificed at 2, 4 and 8 weeks after operation. The specimens were prepared for determination of the expression of TGF-β3 and Smad 6 at scar tissue and the degree of scar adhesion according to Rydell method, and observed the ultrastructure changes of scar tissue with transmission electron microscope. Results At 2 weeks after operation, the expression of TGF-β3 mRNA of two groups were 0.22 and 0.257 ( P = 0.027), respectively. At 4 weeks, group B was was increased significantly, and the mean numbers were 0.362 and 0.411 (P = 0.006). At 8 weeks, the expression of TGF-β3 mRNA of group A was increased significantly, too, but the difference between two groups was significantly, they were 0.427 and 0.470 (P =0.015), respectively. The trend of the expression of TGF-β3 and Smad 6 mRNA was similar. At 2, 4, 8, weeks, the expression was 0.169 and 0.205 (P = 0.089), 0.294 and 0.351 (P = 0.031), and 0.469 and 0.543 (P = 0.021), respectively.In group B the duramater adhesion was decreased (P < 0.05), the proliferation of fibroblasts and fihroblastic function were inhibited (P < 0.05). Conclusions Sodium hyaluronate up-regulated the expression of TGF-β3 and Smad6 and reduced the proliferation and collagen synthesis in fibroblast culture in the scar tissue.
