BACKGROUND: Absorbable material is a hotspot in orthopedics, which is biodegradable, avoids fixation residues and second surgical trauma compared with the traditional internal fixation.OBJECTIVE: To investigate the clinical efficacy and safety of K-wires, screws and absorbable rods for the internal fixation of Mason II-III radial head fractures.METHODS: Totally 45 patients with Mason Ⅱ-Ⅲ radial head fractures were collected from January 2010 to December 2015 admited in Zhangjiagang First People's Hospital and Zhangjiagang Hospital of Traditional Chinese Medicine, and were then divided into three groups (n=15 per group), followed by implanted with K-wires (group A), screws (group B)and absorbable rods (group C), respectively. The baseline data, operation time, blood loss, healing time, Mayo and Broberg-Morrey scores were compared among groups.RESULTS AND CONCLUSION: (1) There were no significant differences in the baseline data, operation time, blood loss,and healing time among groups (P > 0.05). (2) The Mayo scores in the groups A, B, and C were (88.45±6.22),(92.37±5.60), and (90.82±6.58), respectively; the Broberg-Morrey scores in the groups A, B, and C group were ((90.82±6.83), (93.05±6.54), and (91.68±7.15), respectively; all above scores showed no significant differences among groups (P > 0.05). (4) The total incidence rate of complications in the groups A, B, and C was 20% (2/15), 13% (2/15),and 7% (1/15) respectively, showing no significant difference among groups (P > 0.05). (4) These results indicate that the absorbable rods can obtain satisfactory treatment outcomes for Mason II-III radial head fractures, which is equivalent to the traditional internal fixation. Moreover, it can avoid secondary operation for removing internal fixators and the adverse impact of stress shielding, so it is recommended to be used in clinic.

Objective To investigate the changes and pathogenic significance of serum interleukin-12p70 (IL-12), intefferon-γ,(IFN-γ) and IL-4 in the course of hemorrhagic fever with renal syndrome(HFRS). Methods Twenty five eases were divided into mild group (14 eases) and severe group (11 cases) according to the severity of illness. Blood samples were collected in various stages(fever, hypotensian and oliguria,diuresis stage). Serum IL-12 and IFN-γ levels were determined by enzyme-linked immunoserbent assay(ELISA), IL-4 by radioimmunoassay (RIA), blood urea nitrogen (BUN) and platelet by automatic biochemical analyzer and blood analyzer. Results Serum IL-12 levels in mild and severe groups were significantly different during various stages of HFRS (F=5.765, P<0.01). The IL-12 level of both patient groups significantly increased(P<0.01) in fever[ (0.87±0.38), (1.08± 0.77)μg/L], hypotension and oliguria [ (0.77±0.21), (2.11±2.13)μg/L] ,and diuresis stage [ (1.42±1.10), (1.20±0.88)μg/L], compared with control group [(0.56±0.10)μg/L]. In various stages, IFN-γ levels of both case groups were respectively (8.04±13.05), (5.94±8.24), (15.95±18.05), (4.41±4.10), (1.09±1.24), (1.38±1.74), (1.12±1.26), (0.19±1.29)μg/L, and the difference was statistically significant compared with control [ (0.27±0.15)rig/L]. K,-4 levels did not change significantly in the stages(F=0.682, P0.05), while the ratios of IFN-γ and IL-4 contents in mild and severe cases were significantly higher than control [(0.36±0.26) μg/L] in fever[ (2.46±3.52), (16.92±22.77)p.g/L], hypotension and oliguria[(2.52±2.72), (1.77±2.06) μg/L],diuresis stage [(1.45±2.28), (2.32±3.98)μg/L], the difference had statically significant (P<0.05 or 0.01).The curve of IL-12 was similar to that of BUN, but was contrary to blood platelet count. Conclusions The elevated levels of IL-12 and IFN-γ, with the imbalance of Th1/Th2 might be the main cause of systemic inflammatoryresponse and involved in the pathogenesis of HFRS.

Objective To assess the various features of Budd-Chiari syndrome(BCS)on three- dimensional contrast-enhanced magnetic resonance angiography(3D CE MRA)and to evaluate the potential value of this new technique.Methods Thirty-three patients with BCS underwent 3D CE MRA examination. In 23 cases,BCS was secondary to hepatocellular carcinoma(21 patients)or right adrenal carcinoma (1 patient)or thrombophlebitis(1 patient).Ten patients had primary BCS.The patency of the hepatic veins,inferior vena cava(IVC)and portal veins were assessed.The presence of intra-and extrahepatic collaterals,liver parenchymal abnormalities and porto-systemic varices were evaluated.The diagnosis on 3D CE MRA was correlated with that on inferior vena cavography and right hepatic venography,which were available in 10 and 2 cases respectively.Results Various features of BCS were displayed on 3D CE MRA. Hepatic venous findings included tumor thrombosis(19 patients),tumor compression(2 patients), nonvisualization(4 patients)and focal stenosis(4 patients)of the hepatic veins.IVC findings were severe stenosis or occlusion(10 cases),tumor direct invasion(2 cases),tumor thrombosis(3 cases), thrombophlebitis(1 case)and web formation(3 cases).Intrahepatic collaterals were demonstrated in 9 patients including 2 with "spider web" sign.Detected extrahepatic collaterals included dilated azygos and hemiazygos veins(13 cases)and left renal-inferior phrenic-pericardiophrenic collaterals(2 cases).The occlusion of the left portal vein and the presence of porto-systemic varices were depicted in 2 and 10 patients respectively.Liver parenchymal abnormalities identified by 3D CE MRA consisted of caudate lobe enlargement(7 cases),heterogenous enhancement(18 cases)and associated tumors(18 cases). Compared with inferior vena cavography and hepatic venography,the accuracy of 3D CE MRA in the diagnosis of IVC obstruction or hepatic venous stenosis was 100%.Conclusion 3D CE MRA can display various features of BCS and has the potential to provide an accurate diagnosis.
