Objective To investigate the relation between coagulation disorders and sepsis severity of infected patients.Methods In this retrospective study,75 patients,51 males,24 femalse,with age(55.8± 18.1),were included from January 2010 to March 2011.They were clinically diagnozed as infection,and had Thromboelastography(TEG)and routine coagulation test within 24 hours after admission to emergency department.They were divided into 3 groups based on SIRS and SOFA score within 24 hours after admission:a)infection group,patients without SIRS; b)sepsis group,patients with SIRS and SOFA score less than 5; c)severe sepsis group,patients with SOFA score greater than or equal to 5.LSD was used to compare between two groups if one-way ANOVA of three groups comparasion showed significant differences.Results In comparasion to sepsis group(n =29)and infection group(n =27),D-dimer elevated significantly in severe sepsis group(n =19)(F =3.388,P =0.004),and platelet count decreased significantly(F =3.839,P =0.026),INR and KPTT showed an increase trend without significant difference (F =2.657,P =0.077 ; F =2.782,P =0.069); TEG showed MA obviously decreased(F =5.841,P =0.004),while there were nostatistically significant differences among other data.Conclusions The extent of coagulation disorders and sepsis severity of infected patients is closely correlated to each other.

BACKGROUND:Previously, serious thoracolumbar burst fractures with spinal cord injury were mainly treated by anterior surgery. The superiority of conventional posterior repair lies in strong reduction and fixation effects. However, it is difficult to fuly decompression. The anterior and central cylinders of the injured vertebra cannot receive good reconstruction. Loss of correction and internal fixation failure always appear. It remains controversial which repair method is more ideal. OBJECTIVE:To comparatively analyze the effect of posterior and anterior approaches with subtotal vertebrectomy, decompression, reconstruction of spine, and internal fixation for patients with thoracolumbar burst fractures. METHODS: The data of 42 patients with thoracolumbar burst fracture treated by anterior and posterior approaches with subtotal vertebrectomy, decompression, and reconstruction of spine from May 2006 to December 2012 was retrospectively analyzed. They were divided into two groups according to the surgical procedures: anterior approach group (n=23) and posterior approach group (n=19). They were folowed up for at least 24 months. Repair results and imaging results were compared in patients of both groups. RESULTS AND CONCLUSION:None patients in the two groups affected fixator loosing or breakage, and obtained good bone fusion. The intraoperative blood loss was more and operative time was longer in the anterior approach group than in the posterior approach group, showing significant difference (P < 0.05). The pulmonary function was significantly better in the posterior approach group than in the anterior approach group (P < 0.05). Visual Analog Scale score, Japanese Orthopaedic Association score for back pain and Frankel classification were significantly improved during final folow-up compared with pre-treatment in both groups, but no significant difference was found between groups (P > 0.05). No significant difference in the anterior vertebral height and kyphosis Cobb angle was detected before treatment, at 1 week after treatment and during final folow-up (P > 0.05). The incidence of postoperative complications was significantly higher in the anterior approach group than in the posterior approach group (P < 0.05). These findings confirm that subtotal vertebrectomy through anterior approach and posterior approach can effectively repair thoracolumbar burst fractures. However, the complications of posterior approach are less, and posterior approach has few impacts on the pulmonary function, is safe, and has good biocompatibility with the host.

Objective To investigate the clinical efficacy of electroacupuncture in treating mild and moderate female stress incontinence.Methods One hundred and eighty female patients with mild or moderate stress incontinence were randomly allocated to treatment and control groups, 90 cases each. The treatment group received electroacupuncture and the control group took midodrine hydrochloride tablets. The International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI SF) score was recorded and 1-hour pad test leakage was measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant pre-/post-treatment differences in the ICIQ-UI SF score and pad test leakage in both groups (P<0.01). There were statistically significant post-treatment differences in the ICIQ-UI SF score and pad test leakage between the treatment and control groups (P<0.01). The total efficacy rate was 86.7% in the treatment group and 68.9% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusions Electroacupuncture is an effective way to treat mild and moderate female stress incontinence. It can improve urinary continence and reduce urine leakage in the patients.

Objective To investigate the characteristics of early changes in serum IL-17 and IFN-γ levels in elderly patients with acute myocardial infarction (AMI).Methods 70 hospitalized elderly patients with AMI and 35 healthy people were selected.Serum level of interleukin-17 (IL 17) and interferon-γ (IFN-γ) were assayed by enzyme linked immunosorbent assay (ELISA).Results Serum levels of IL17 and IFN-γ showed increasing trends in elderly patients with AMI as compared with that in control group,but there were no significant differences between the two group [(35.73 30.28) pg/ml vs.(28.70±17.12) pg/ml,(15.29±14.64) pg/ml vs.(11.38±10.10) pg/ml,t=0.144 and 0.138,P=0.365 and 0.377].There were correlations between serum IL-17 and IFN γ levels in patients with AMI and controls(r=0.936 and 0.989,both P=0.00).Serum levels of IL-17 or IFN-γhad no significant differences between AMI patients with well and poor prognosis [(35.43± 34.36) ng/L vs.(36.11±30.16) ng/L,(13.90±13.98) ng/L vs.(15.99±14.14) ng/L,U=0.266 and 0.166,P=0.687 and 0.668].Conclusions Serum IL-17 level has an increasing trend in AMI patients within 24h,but has no statistical significant.Serum IL 17 level has a significantly positively correlation with serum IFN γ level in the elderly,but serum levels of IL-17 or IFN γ have no significant correlations with short term prognosis in elderly patients with AMI.

Smad3 is a major transporter in the transforming growth factor β (TGF-β) signaling pathway.It is in charge of the transfer of TGF-β signal from the surface of the cell membrane into the nucleus.The TGF-β signal can be bound to the target gene in the nucleus and regulate its expression.Abnormalities in Smad3 expression level and functional status will lead to abnormal signal transduction,involving cell growth,proliferation,development,differentiation,migration,apoptosis and other basic life activities.This review focused on the differential expression of Smad3 in hepatocellular carcinoma (HCC)and the adjacent tissue.The character of Smad3 in HCC is outlined in three parts:Smad3 upstream signaling source,Smad3 self-assembly maturation and Smad3 downstream effects,which may provide a summary and reference for the follow-up study on Smad3.
