Objective To observe the effects of Melatonin on hippocampal neuron apoptosis and caspase-3 expression in epileptic rats. Methods Using model of status epilepticus (SE) induced by Pilocarpine, the rats were administered with melatonin (melatonin group) or saline (Pilocarpine group) before Pilocarpine injection. The apoptotic neuron was detected by TdT-mediated dUTP Nick End Labeling (TUNEL) and caspase-3 expression was observed by immunocytochemistry method, respectively.Results In Pilocarpine group, the number of TUNEL positive neurons began to increase at 6 h post-SE, peaked at 72 h post-SE, and decreased at 7 d post-SE. Caspase-3 immunoreactivity began to increase at 6 h post-SE, peaked at 48 h post-SE, especially in CA1 and CA3 region of hippocampus, began to decrease at 72 h post-SE and dropped to normal level at 7 d post-SE. The numbers of TUNEL positive neurons and caspase-3 expression in Melatonin group were significantly decreased compared to Pilocarpine group at different time points (all P

Objective The investitgation of vascularized periosteal flap with dorsal branch of anterior interossea vessel was performed to provide anatomical basis for periosteal flap transposition. Methods The courses, branches, distribution and anastomosis of the dorsal branch of anterior interossea vessel were observed on 30 sides of adult cadavers' upper extremities and stimulated operation were perfomed. Results The dorsal branch penetrate out of interosseous membrane of forearm at (6. 6? 1. 4) cm upper the styloid process of the radius. It also sent off branches to the dorsal of ulna and radius that consist the periosteal flap. The dorsal branch send off lateral and medial branch about (2. 6?0. 8) cm upper the styloid process of the radius. The end of the branch anastomoses with dorsal carpal branch of the ulnar and radial vessel' Conclusion The pedicled osteoperiosteal flap can be transferred for repairing the fracture nonunion of ulna and radius and transpose reversely to repair scaphoid and innate bone disease'

Objective To analyze the clinical conditions and emergency treatment experiences of acute and chronic renal failure with hyperpotassemia. Methods Retrospective analyzed 542 clinical cases of supervening hyperpotassemia, which were treated by hemodialysis on 186 patients of renal failure with hyperpotassemia for 5 years. Results 540 cases clinical symptom was improved, serum potassium concentration was down to normal range and hyperpotassemia disappeared in electro cardiogram. 2 cases died after salvage. Rate of success was 99.6%. Conclusion Hemodialysis therapy is the most effective treatment to hyperpotassemia. Use bicarbonate with kalium pH indicator of 3.0~3.5mmol/L in dialysis is useful to lower hyperpotassemia, and safe also. In the early stage of hemodialysis, pure ultrafiltration dehydration treatment is not suitable. There is still danger of heartbeat stop deal to high kalium in the early stage of dialysis; emergency treatments should be standby all the time.

Objective To probe the changes of nitric oxide (NO) content and caspase-3 mRNA expression in hippocampus and the correlation between NO and caspase-3 mRNA expression post-status epilepticus (SE). Methods The models of SE were induced by pilocarpine. The nitric oxide content was detected by chromatometry and caspase-3 mRNA expression was observed by reverse transcription polymerase chain reaction (RT-PCR) method. Results The level of NO increased rapidly at 6~72 h post-SE,and was still significantly higher than that of the controls (all (P)0.05).Conclusions The peak expression of nitric oxide is earlier than caspase-3 mRNA post-SE, although they have the similar diversity tendency. Nitric oxide pathway is definitely involved in the seizure initiation and correlated with caspase-3 activation.

We report a case of a 35-year-old right-handed male patient with drug-resistant mesial temporal lobe
epilepsy who developed ipsilateral occipital hematoma after right temporal anterior lobectomy and
amygdalohippocampectomy. Patient did not report taking any drugs with anticoagulant effect, such
as aspirin or valproate. There was no past history of hypertension and the pre-operation tests were
normal. Pre-operative brain magnetic resonance imaging revealed no abnormality in the right occipital
lobe. Overdraining of cerebrospinal fluid may have triggered this remote cerebellar hemorrhage.

Objecltive To intensify the coordination and nursing in the operation room in order to prevent surgical site infection after gastrointestinal operation. Methods 337 medical history of patients received gastrointestinal operation and third rate healing from 1999 to 2006 were collected. A series of intensified measures were applied to surgical site infection from 2003 gradually, including invocation of new surgical handwashing method, modified skin disinfection manner, adoption of degreasing with ethanol first before disinfection with iodophor, placement of incision protector and clean bag for incision protection after entering abdomen, changing to use new gastrointestinal anastomofic thimerosal,standardization of operation order and clean manage-ment in operation room. The incidence rate of surgical site infection after gastrointestinal operation of patients from 1999 to 2002 and from 2003 to 2006 underwent χ2 test. Results The incidence rate of surgical site in-fection after gastrointestinal operation greatly decreased after adoption of intensified nursing intervention, Signifi-cant difference existed in rate of patients with third rate healing between the year 1999 to 2002 and 2003 to 2006. Conclusions Modified nursing intervention for surgical incision after gastrointestinal operation can de-crease incision infection rate evidently.

Objective To explore the spread patterns of retropharyngeal lymph node (RLN) metastasis of nasopharyngeal carcinoma. Methods From July 2003 to March 2005, three hundred and three patients with nasopharyngeal carcinoma in initial treatment were enrolled in this study. All patients underwent magnetic resonance imaging (MRI) before treatment, meanwhile measured the minimal and maximal axial diameters, the longitudinal diameter and the central and craniocaudad locations of each positive RLN. Results A total number of 264 positive RLN were found in 177 patients. The minimal and maximal axial diameters and longitudinal diameter of positive RLN were 9.9, 12.9 and 22.4 mm, respectively. Ipsilateral metastatic RLN were noted as follows: two nodes in 21 patients, three nodes in 3 patients and four nodes in 1 patient. According to the longitudinal central location of 263 positive lateral RLN, the numbers of nodes at occipital bone, C1, C1/C2, C2, C2/C3 and C3 were 27, 166, 40, 23, 5 and 2, respectively; the mean minimal axial diameters of nodes were 6.8, 9.9, 12.5, 10.4, 9.3 and 8.0 mm, respectively. Conclusion Multiple metastatic ipsilateral RLN are not common in NPC. The rate of RLN metastasis shows the trend of decreasing from vertebral C1 to C3.The maximal diameters of RLN are in the C1/C2 intervertebral space, and reveal a decreasing frequency along the craniocaudal directions of occipital and vertebral C1.
