Post traumatic epilepsy(PTE)refers to the epileptic seizures after traumatic brain injury. Or-ganic damage can be found by imaging examination, and abnormal electroencephalogram can be detected via electroencephalogram examination which has the similar location of the brain injury. PTE has the characteristics of low incidence, absence of case reports, and easy to exaggerate the state of illness, which add difficulties to the forensic identification. This paper reviews the status of epidemiology, patho-genesis, clinical treatment and forensic identification for PTE.

Objective To evalute the effects of subcutaneous transfection of human beta-nerve growth factor (Ad-hNGFβ) gene on the function of sensory nerve in a rat model of diabetic neuropathic pain (DNP).Methods Healthy male Sprague-Dawley rats,weighing 180-220 g,were used in this study.Ten rats were randomly collected as normal control without DNP (group C).DNP model was established by intraperitoneal injection of streptozocin (STZ) 75 mg/kg.Seventy-five rats with DNP were randomly divided into 3 groups (n =25 each):DNP group; Ad-hNGF group and Ad-LacZ group.Groups Ad-NGF and Ad-LacZ received subcutaneous transfection of 1.12 × 1011 PFU Ad-hNGFβ 10 ul and 1.12 × 1011 PFU Ad-LacZ 10 ul respectively after pain thresholds were measured on 21 days after STZ injection.The mechanical and thermal pain thresholds were measured before STZ injection (baseline) and at 21,35 and 49 days after STZ injection.The conduction velocity and latency of the sensory nerve and the expression of substance P (SP) in dorsal root ganglion (by immmuno-histpchemistry) were determined after measurement of pain threshold on 49 days after STZ injection.Results Compared with group C,the mechanical and thermal pain thresholds were significantly increased at each time point after STZ injection in groups DNP,Ad-NGF and Ad-Lacz,the conduction velocity of the sensory nerve was significantly decreased,the latency of the sensory nerve was prolonged,and the expression of SP in dorsal root ganglion was down-regulated in groups DNP and Ad-LacZ,the conduction velocity of the sensory nerve was significantly decreased (P < 0.05),and no significant change was found in the latency of the sensory nerve and expression of SP in dorsal root ganglion in group Ad-NGF (P > 0.05).Compared with group DNP,the thermal pain threshold was significantly increased at 49 days after STZ injection,the conduction velocity of the sensory nerve was decreased,the latency of the sensory nerve was shortened,and the expression of SP in dorsal root ganglion was down-regulated (P < 0.05 or 0.01),while no significant change was found in the mechanical pain threshold in group Ad-NGF,and no significant change was found in the parameters mentioned above in group Ad-LacZ (P > 0.05).Conclusion Subcutaneous transfection of Ad-hNGFβ can improve the function of sensory nerve in a rat model of DNP through up-regulat-ing of the SP expression in dorsal root ganglion.

Objective To compare different nursing methods impacting on the wound healing effects of circumcision for patients with Chinese Shang ring circumcision. Methods A total of 144 male patients with Chinese Shang ring circumcision were randomly divided into A and B group by coin tossing. The patients of A group received circumcised dressing to wrap wound with dressing change 3 times/week;the patients of B group had no dressing for wound to exposure wound and keep wound dry. Followed interviewed 2 months after operation, we compared the incision edema, the infection, rate of incision rupture, postoperative pain, wound healing time, satisfaction of incision appearance and so other indexes between two groups. Results The patients in the group B suffered less pain when erected in 2 weeks after operation (P<0. 05). The length of healing time in B group was (25.9 ±4.7) d, shorter than (27.8 ±5.0) d in the group A (P<0.05). The postoperative incision edema, incision rupture, infection and satisfaction of incision appearance were no statistical significance between two groups (P>0. 05). Conclusions To exposure the incision and keep it dry after Chinese Shang ring circumcision can minimize the level of pain and length of wound healing, and is worthy to promote.
