Objective:To evaluate the role of nucleotide-binding oligomerization domain-2 (NOD2) in dorsal root ganglion in the development of neuropathic pain (NP) in rats.Methods:Thirty-two adult male SPF Sprague-Dawley rats, weighing 240-260 g, aged 2-3 months, were divided into 4 groups ( n=8 each) using a random number table method: control group (group C), NP group (group S), negative control siRAN group (group N), and NOD2-siRNA group (group R). In N and R groups, 1×10 8 IFU/ml negative control siRNA and NOD2-siRNA 10 μl were intrathecally injected, respectively, once a day for 3 consecutive days.Normal saline 10 μl was intrathecally injected once a day for 3 consecutive days in C and S groups.The model of NP was established using spared nerve injury (SNI) at 2 weeks after intrathecal injection.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before surgery and 1, 3, 7, 10, 14 and 28 days after SNI.Animals were sacrificed after measuring pain threshold on day 28, and the dorsal root ganglions (DRGs) of the lumbar segment (L 4-6) were removed for determination of the expression of NOD2 (by Western blot) and expression of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), IL-6 and NOD2 mRNA (using quantitative real-time polymerase chain reaction). Results:Compared with group C, MWT was significantly decreased at each time point after SNI, and the expression of NOD2 protein and mRNA and TNF-α, IL-1β and IL-6 mRNA in DRGs was up-regulated in group NP ( P<0.01). Compared with group NP, MWT was significantly increased at each time point after SNI, and the expression of NOD2 protein and mRNA and TNF-α, IL-1β and IL-6 mRNA in DRGs was down-regulated in group R ( P<0.01), and no significant change was found in the parameters mentioned above in group N ( P>0.05). Conclusion:The mechanism underlying the development of NP may be related to the up-regulation of NOD2 expression in DRGs, thus further promoting the expression of pro-inflammatory factors in rats.

Objective To compare the epidemiological characteristics of adult single fractures of the cuneiform between the east and west areas in China from 2010 through 2011.Methods Thirty-five hospitals in the east coast area (group A) and 28 hospitals in the west inland area (group B) were selected for this investigation. The data of adult single fracture of the cuneiform treated between January 2010 and De-cember 2011 at the 63 hospitals were collected through the PACS system and medical records inquiry system. The epidemiological characteristics concerning age, gender and fracture classification were compared between the 2 groups. Results A total of 457 adult single fractures of the cuneiform were collected, involving 384 cases in group A and 73 cases in group B. They accounted respectively for 4.38% (384/8,772) and 3.53% (73/2, 068) of the adult tarsal bone fractures in the same period, showing no significant difference (P >0.05), accounted respectively for 1.71% (384/22, 455) and 1.15% (73/6, 354) of the adult foot frac-tures, showing a significant difference (P <0.05), and accounted respectively for 0.20% (384/192,991) and 0.09% (73/81, 143) of all the adult fractures, showing a significant difference (P <0.05). The median age was 39 years in group A (29, 50) and 36 years in group B (25, 45), showing a significant difference (P <0.05). The male to female ratio was 1.61:1 (237/147) for group A and 1.52:1 (44/29) for group B. The peak age range of the fracture for males was from 21 to 30 years old in both groups, and its proportion was 28.69% (68/237) in group A and 38.64% (17/44) in group B. The peak age range of the fracture for females was from 41 to 50 years old in both groups, and its proportion was 26.53% (39/147)in group A and 27.59% (8/29) in group B. All the above comparisons were statistically insignificant (P> 0.05). The proportion of the age group of≥61 years was significantly larger in group A than in group B (P <0.05). The high risk type of the fracture was type 85-A1 in both groups, and its proportion was 61.98% (238/384) in group A and 52.05% (38/73) in group B. The proportion of type 85-B1 was significantly larger in group B than in group A (P <0.05). Conclusions Adult single fractures of the cuneiform were more common in young and male patients. The proportion of elderly patients (≥61 years old) was significantly larger in the east area. The high risk type of the fracture was simple fracture involving the medial cuneiform bone (type 85-A) in both areas. The proportion of the comminuted fracture of the medial cuneiform (type 85-B1) was significantly larger in the west area.
