BACKGROUND: Some studies suggest that pre-injection of tumor necrosis factor-α (TNF-α)can protect focal cerebral ischemia in mice. Cerebral ischemia tolerance is related to the increase of TNF-α level; on the other hand, TNF-α is an injurious cytokine associated with stroke. Circulating antibody against anti-TNF-α can protect reperfused injury.OBJECTIVE: To study the effects of TNF-α pretreatment and post-treatment on cerebral ischemia-reperfusion injury and explore possible mechanism.DESIGN: Randomized controlled study.SETTING: Neurological Department, the Second Hospital Affiliated to Harbin Medical University.MATERIALS: The experiment was conducted at the Animal Experiment Center of Harbin Medical University from January to April 2002. Totally 120 healthy adult male Wistar rats were randomly divided into the following 8 groups: TNF-α 0.05 μg, 0.5 μg and 1.0 μg pretreatment groups and PBS group, TNF-α 0.05 μg, 0.5 μg and 1.0 μg post-treatment groups and PBS group with 15 in each group.METHODS: The focal brain ischemia model of middle cerebral artery occlusion (MCAO) was made using inserting thread method. TNF-α of different doses (0.05 μg, 0.5 μg or 1.0 μg) or PBS was injected intracisternally and 22-hour reperfusion, 8 rats from each group were killed. Then the perhour reperfusion, 7 rats from each group were killed. Then pathological changes were observed, glial fibrillary acidic protein (GFAP) and intercellular adhesion molecule-1 (ICAM-1) expression were inspected by immunohistochemical method. Histopathological and immunohistochemical evaluation was made with the computer-assisted image analyzing system,and the number of GFAP positive cells and ICAM-1 positive vessels in each hemisphere was counted.riliary acidic protein and ICAM-1.infarct volume: TNF-α 0.5 μg and TNF-α 1.0 μg pretreatment groups showed reduced volume of lesion; infarct volume reduced by 70.9% in TNF-α 0.5 μg pretreatment rats and 66.5% in TNF-α 1.0 μg pretreatment rats. TNF-α 0.5 μg and TNF-α 1.0 μg post-treatment groups showed increased volume of lesion; infarct volume increased by 22.3% in TNF-α 0.5 μg post-treatment rats and 46.7% in TNF-α 1.0 μg post-treatment rats.TNF-α 0.05 μg and 1.0 μg pretreatment groups did not differ significantly (P ＞ 0.05), but there was an obvious difference between TNF-α 0.5 μg and pared with PBS pretreatment group, TNF-α 0.5 μg and 1.0 μg pretreatment groups showed lessened tissue damage and edema. Compared with PBS post-treatment group, TNF-α 0.5 μg and TNF-α 1.0 μg post-treatment fibriliary acidic protein and ICAM-1: TNF-α 0.5 μg and TNF-α 1.0 μg pretreatment groups showed reduced volume of glial fibriliary acidic protein and ICAM-1 (P ＜ 0.05); but TNF-α 0.5 μg and TNF-α 1.0 μg posttreatment groups showed increased volume of glial fibriliary acidic protein and ICAM-1 (P ＜ 0.05). TNF-α 0.05 μg and 1.0 μg pretreatment groups did not differ significantly (P ＞ 0.05); but there was an obvious difference between TNF-α 0.5 μg and 1.0 μg post-treatment groups (P ＜ 0.05).cerebral ischemia reperfusion injury. This effect is not related to the repair given after cerebral ischemia reperfusion, ischemia exacerbates, which is α are determined by whether TNF-αis given before or after cerebral ischemia in a dose-dependent manner.

Objective To investigate the imaging diagnosis and surgical treatment of intestinal malrotation in adult patients. Methods The clinical data of 11 adult patients with intestinal malrotation who had been admitted to General Hospital of PLA from January 2003 to December 2007 were retrospectively analyzed. Multiple imaging modalities, including barium enema, gastrointestinal radiography, B sonography, computed tomography (CT) scan and mesenteric angiography were applied for diagnosis. All patients received Ladd procedure. Results Two patients were diagnosed by gastrointestinal radiography +B sonography, 4 by gastrointestinal radiography +CT scan, 1 by angiography, 1 by B sonography + CT scan, 1 by iodine radiography + CT scan and 2 by intraopera-tive examination. After the operation, 2 had renal insufficiency, 1 had intestinal fistula and 1 had short bowel syndrome and died at the third month after operation. Conclusion Combined application of multiple imaging modalities can improve the diagnostic rate, and Ladd procedure is effective and safe for adult patients with intes-tinal malrotation.

Background and purpose:Postoperative sore throat (POST) is one of the common complaints of patients after radical thyroidectomy. Tracheal intubation is the main cause of POST. This study compared the effect of intubation with visual endoscopy and general laryngoscope on POST in patients undergoing radical thyroidectomy. Methods:One hundred patients (18-60 years, ASAⅠ-Ⅱ) undergoing elective radical thyroidectomy were randomized into two groups:patients in group A (n=50) were intubated with visual endoscope while patients in group B (n=50) were intubated with general laryngoscope. Endotracheal tube cuffs pressure was maintained at 20mmHg in all patients. Visual analogue scale (VAS) and Bruggrmann comfort scale (BCS) were recorded at the time points of 1, 6 and 24 h after extubation. Results:Compared with group B, the incidence of POST in group A was signifcantly reduced (42%vs 64%, P=0.027). The VAS of group A was lower than that of group B (3.05±1.56 vs 4.25±1.30, 3.05±1.56 vs 4.01±1.98, 2.72±1.77 vs 3.31±1.12) (P<0.05). The BCS of group A was higher than that of group B (0.99±0.46 vs 0.69±0.30, 1.95±0.47 vs 1.51±0.58, 2.82±0.87 vs 2.31±0.72) (P<0.05). Conclusion:Using visual endoscopic intubation can reduce the incidence of the POST in patients undergoing radical thyroidectomy.

ObjectiveTo report clinical, pathological and molecular genetic features in a Chinese family with hereditary motor and sensory neuropathy type 6. MethodsThe index case is a 15 years old boy.He developed progressive distal limb weakness at the age of 5.The disease deteriorated slowly,accompanied with contracture of achilles' tendon. At the age of 11 years old he suffered from decrease of visual acuity. At the age of 12, he found the muscular atrophy of both hands without sensory disturbances.Visual evoked potential revealed prolonged latency of bilateral P100. Ophthalmological examination showed bilateral optic atrophy. His mother had the similar symptoms at the age of 7 and reduced visual acuity at the age of 10. Nerve conduction velocity revealed in both pat1ents no compound motor and sensory nerve action potentials in most nerves or slightly reduced nerve conduction velocities with severely reduced amplitudes of the compound motor and sensory nerve action potentials. Sural nerve biopsy was performed on the proband.The sequence of MFN2 gene was analyzed in DNA from the index, his mother and 100 healthy controls.ResultsSural nerve biopsy revealed severe loss of myelinated fibers with few regenerating clusters.Ultrapathological examination showed a few of atypical bulbs of myelinated fibers, occasionally regenerating clusters, mitochondrial swelling and aggregation in a few of axons. A new mutation of W740R mutation in MFN2 gene has been identified in the index case, her mother, but not in 50 healthy controls. Conclusions A novel MFN2 gene mutation result in hereditary motor and sensory neuropathy type 6.Mild visual loss appeares after the lesion of spinal nerves. Demyelination of peripheral nerve appears in the disease.

Objective To explore influences of improved intramuscular injection on quality of benzathine benzylpenicillin medication.Methods The cluster random sampling was adopted to select 178 patients who needed injection of 240U benzathine benzylpenicillin.A self-control study design was used,and benzathine benzylpenicillin was injected in both sides with each of 1 200 000 units.The left side was injected via routine method,while the right side was injected by an improved intramuscular injection.One-time success rate,degree and duration of pain during and after injection were recorded.Results The differences of one-time success rate,pain during injection,pain after injection,duration of pain after injection and incidence of induration after injection between two groups were statistically significant(P＜0.01).Conclusion The improved intramuscular injection can improve one-time success rate of benzathine benzylpenicillin,reduce pain during injection and local pain after injection,shorten duration of pain and decrease incidence of induration after injection.

Many applications of wireless sensor networks can benefit from fine-grained localization. In this paper, we proposed an accurate, distributed localization method based on the time difference between radio signal and sound wave. In a trilateration, each node adaptively chooses a neighborhood of sensors and updates its position estimate with trilateration, and then passes this update to neighboring sensors. Application examples demonstrate that the proposed method is more robust and accurate in localizing node than the previous proposals and it can achieve comparable results using much fewer anchor nodes than the previous methods.
