Objective To discuss the operative methods, timing and outcomes of severe open Pilon fractures. Methods From April 2003 to July 2008, 21 patients with open Pilon fractures were admitted. All the patients were type C fracture according to AO/OTA classification, including 17 cases of type C2 and 4 cases of type C3. According to Gustilo classification, there were 18 cases of type Ⅱ, 2 cases of type ⅢA, 1 case of type ⅢB. The patients were treated in two different ways: one-stage minimally invasive osteosynthesis for reconstruction of the articular surface with transarticular external fixation of the ankle (19 cases),which included 16 cases of Gustilo Ⅱ AO/OTA C2, 2 cases of type Gustilo Ⅱ AO/OTA C3 and 1 case of type Gustilo ⅢA AO/OTA C2. Formal open reconstruction of the articular surface by plating and external fixation was performed when the condition of soft tissue had improved (2 cases), which included 1 cases of type Gustilo ⅢA AO/OTA C3 and 1 cases of type Gustilo Ⅲ B AO/OTA C3. Results All the patients were followed up from 6 to 48 months, with the mean of 24 months. The outcome of reduction was evaluated by the Burwell-Charnley score. Anatomical reduction was found in 6 cases, function reduction was in 14 cases and poor reduction was 1 case. The heal-time ranged from 2.5 to 11 months, with the mean of 4.7 months. The delayed union occurred in 2 cases. The rate of delayed union was 9.5%. Two patients experienced skin superficial necrosis. There were superficial infection in 2 cases and deep infection in 1 case. The infection rate was 14.3%. Eight cases experienced early traumatic arthritis. The incidence of this complication was 38.1%.According to American Orthopedic Foot Ankle Society (AOFAS) scale for ankle joint, the result of the treatment was 66-94, with an average of 85.2. Conclusion It is important to have the optimal timing of surgery and reliable fixation according to fracture classification, the condition of soft tissue and time after injury. It is the key to evaluate the condition of soft tissue and protect the blood supply.

Objective To investigate the most sensitive methods for diagnosing spontaneous internal carotid artery dissection (sICAD) and spontaneous vertebral artery dissection (sVAD) respectively,for the sake of earlier and more accurate diagnosis.Methods Consecutive patients with sICAD and sVAD who visited the Department of Neurology and Radiology,Huashan Hospital Affiliated to Fudan University during 2008-2013 were retrospectively reviewed and the sensitivity of CT angiography (CTA),magnetic resonance T1-weighted fat-suppressed images (MR T1-FS) and digital subtraction angiography (DSA) for the diagnosis of sICAD and sVAD was compared.Results Eighty patients (62 male,18 female; mean age (45.7 ± 11.9) years) were included in the study.There were 99 arterial dissections in total,45 cases of sICAD,52 cases of sVAD and 2 cases of spontaneous middle cerebral artery dissections.The sensitivity of CTA,DSA and MR T1-FS for diagnosing sICAD was 97.5％ (39/40),90.0％ (36/40) and 69.6％ (16/23) respectively,while for sVAD was 89.8％ (44/49),84.6％ (44/52) and 100.0％ (27/27) respectively.Conclusions sICAD and sVAD have significant differences in many aspects including diagnostic strategies.CTA and MR T1-FS seem to be the most sensitive methods for the diagnosis of sICAD and sVAD respectively.Although DSA has been considered as the gold standard for the diagnosis of artery dissection,this imaging technique does not allow analysis of artery wall thickness,thus also has limitations.It is likely that the diagnostic sensitivity will be improved by combining CTA and MR T1-FS.

Objective To evaluate the role of interleukin?1β( IL?1β) in activation of N?methyl?D?aspartate ( NMDA) receptors in spinal dorsal horns of rats with neuropathic pain. Methods One hundred twenty?eight pathogen?free healthy adult male Sprague?Dawley rats, weighing 200-250 g, were divided into 4 groups (n=32 each) using a random number table: control group (group C), recombinant adenovirus vector group ( group rAd) , recombinant adenovirus vector shRNA group ( group rAd∕shRNA) , and recom?binant adenovirus vector shRNA plus recombinant adenovirus vector IL?1β group ( group rAd∕shRNA+rAd∕IL?1β) , receiving intrathecally injected equal volume of 0.9% sodium chloride solution, recombinant ade?novirus vector, recombinant adenovirus vector shRNA, and recombinant adenovirus vector shRNA plus re?combinant adenovirus vector IL?1β5 μl, respectively. Chronic compression of dorsal root ganglia was per?formed on 8th day after intrathecal injection. The thermal paw withdrawal latency ( TWL) was measured at 1 day before intrathecal injection ( T0 ) and at 1, 2, 3 and 5 weeks after intrathecal injection ( T1-4 ) . After measurement of the pain threshold at each time point, 8 rats selected randomly were anesthetized and sacri?ficed, and the lumbar enlargement segments of the spinal cord were harvested for determination of the ex?pression of IL?1β and phosphorylated NMDA receptor NR1 subunits at serine 896 ( pNR1S896) in spinal dorsal horns on the injured side by immunohistochemistry and Western blot. Results Compared with group C, the TWL was significantly prolonged, and the expression of IL?1βand pNR1S896 in spinal dorsal horns was significantly down?regulated at T2-4 in group rAd∕shRNA (P<0.05), and no significant change was found in the parameters mentioned above at each time point in group rAd and group rAd∕shRNA+rAd∕IL?1β( P>0.05) . Compared with group rAd, the TWL was significantly prolonged, and the expression of IL?1βand pNR1S896 in spinal dorsal horns was significantly down?regulated at T2-4 in group rAd∕shRNA ( P<0.05) , and no significant change was found in the parameters mentioned above at each time point in group rAd∕shRNA+rAd∕IL?1β (P>0.05). Compared with group rAd∕shRNA, the TWL was significantly short?ened, and the expression of IL?1β and pNR1S896 in spinal dorsal horns was significantly up?regulated at T2-4 in group rAd∕shRNA+rAd∕IL?1β ( P<0.05) . Conclusion IL?1β is involved in the activation of NM?DA receptors in spinal dorsal horns of rats with reuropathic pain.
