Idiopathic optic neuritis (ION) is a common disorder in neuro-ophthalmology. It harms vision function seriously. However, there are a lots of controversy and confusion about its etiology, etiopathogenesis and outcome of treatments. Recently, potassium channel, such as stichodactyla helianthus peptide (ShK) and TRAM-34, was found to be involved in the immunopathogenesis of ION, and regulation of potassium channel provide a novel immunomodulatory therapy for ION. This paper reviewed the research advance of potassium channel in ION. It is expected to further clarify the pathogenesis and search for effective treatment.

Diabetic foot is one of the most common and serious complications of diabetes. Early detection and prompt treatment is of great significance to the prevention of diabetic foot. Imaging is the most convenient and effective method for making an early diagnosis of diabetic foot, and imaging examination can directly and accurately reveal the peripheral vascular disorders, peripheral neuropathy, soft tissue complications, muscle and tendon lesions, bone complications, etc. thus the lesion’s extent can be exactly evaluated, which provides reliable basis for the selection and evaluation of the clinical therapeutic scheme. This paper aims to make a general review about the recent imaging research progress in diabetic foot.

Objective To study the relationship between ankle-brachial index and all cause mortality and cardiovascular disease mortality in female Chinese patients with atherosclerotic risk factors.Methods A total of 1744 female patients with no less than two atherosclerotic risk factors were enrolled from several hospitals in Shanghai and Beijing.Baseline exams were measured.All the participants were followed up 13 months.Results The patients with PAD were significantly older than those without PAD[(72.42?9.158)years vs(65.89?10.366)years,P

ObjectiveTo evaluate surgical management of femoral pseudoaneurysm caused by injection of addictive drugs.MethedsData of 18 cases were reviewed and analysed retrospectively.13 patients underwent primary expanded polytetrafluoroethylene(ePTFE) external iliofemoral bypass (end to side) grafting. Postoperative anastomotic burst and bleeding in one of the 3 patients undergoing saphenous vein autotransplant in situ was successfully treated by ePTFE grafting. Results All of the grafts were patent as demonstrated by postoperative color Dopler ultrasonography. Although 2 patients had their femoral arteries ligated, limbs of all the 18 patients were salvaged.ConclusionsWhen a suitable saphenous vein is not available for autotransplantation, an artificial vessel grafting is still an effective procedure for managing femoral artery false aneurysm.During operation thorough debridement and avoidance of artificial vessel contamination are the most important factors for preventing infective complications of the graft.

Objective To discuss the feasibility on reducing the postoperative pulmonary complications ( PPC) incidence after thoracot-omy on chronic obstructive pulmonary disease ( COPD) though application of incentive spirometry ( IS) . Methods 62 patients with COPD concurrent thoracotomy were divided into control group and observation group,the control group was given routine nebulization,expectoration and other physical treatment;the observation group were given IS besides the conventional treatment. The incidence of PPC,prognosis,and the changes on pulmonary function were compared between these two groups. Results The incidence of PPC and mortality of observation group were significantly lower than those of control group,and the inspiratory capacity( IC) from 3~5 days was significantly higher than that of con-trol group. Conclusion Application of IS can reduce the PPC incidence after thoracotomy on COPD patients,and promote the recovery of pulmonary function.

Objective To explore diagnosis and treatment of thoracolumbar spine and spinal cord trauma complicated by thoracoabdominal viscera injury. Methods A retrospective study was performed on 84 cases with thoracolumbar spine and spinal cord trauma complicated by thoracoabdominal viscera injuries treated in our unit from January 1986 to December 2002, of which there were 52 cases with thoracic vertebra fracture (T_6-T_(12)), 32 with lumbar fracture (L_1-L_4), 70 with complicated chest injury, 14 with abdominal injury and 34 with injuries of cranium, extremities and pelvis. Spinal fixation or decompression of spinal cord was performed in 62 cases, drainage in 22, laparotomy in 10 and exploration of skull in nine. Results Eighty-two cases survived, with follow up period for 6-36 months. According to Frankel standard nerve function recovery showed that among 36 cases at grade A, 10 had partial or sensation recovery and the other got nerve function improvement for gradeⅠ-Ⅲ. Delayed diagnosis and missed injuries totaled seven cases (12%). Two cases were died of postoperative MODS. Conclusions As for patients with thoracolumbar spine and spinal cord trauma complicated by thoracoabdominal viscera injury, a comprehensive clinical examination including X-ray or CT is necessary. The treatment should first focus on thoracoabdominal viscera trauma and try to avoid aggravation of spine and spinal cord injury.

Objective To study the effects of Glycyrrhiza polysaccharide (GP) on immune function in mice. Methods Polysacchayide was extracted from Glycyrrhiza uralensis by water-extraction-alcohol-precipitation method. Ovalbumin was injected to mice as antigens. The mice were randomly divided into four group:low (50 mg/kg), middle (100 mg/kg), high (200 mg/kg) dosage group of GP and normal control group, 12 mice in each group. Four groups were given GP and NS orally for seven days. After the secondary immunization, the level of antibody and the concentration of serum IFN-? were determined. Results The levels of antibodies and cytokines in middle and low dosage group of GP were all significantly higher than those of control group. Conclusion GP could enhance the immune function of mice.

Objective To evaluate the influence of diet structure and physical activity on the lipid level in different area of China.Methods A total of 145 people were selected by simple random sampling,including 52 residents,45 urban residents of Panzhihua and 48 rural residents of Panzhihua,each of them undergoing the laboratory examination and dietary and physical activity survey.Food frequency questionnaire and physical activity questionnaire were used.Results The blood sugar,TC and LDL-C level in Shanghai residents were higher than those of urban and rural residents of Panzhihua(P0.05)while the energy exhaust of Shanghai residents was higher than those of urban and rural residents of Panzhihua(P

The lineage-Actinobacteria class nov.comprises organisms with a DNA base composition which generally is above 50% G+C (with a few exceptions).We set up a method that has been used in isolating Actinobacteria and Actinomycetes. We added 25?g/mL Nalidixic acid and 25?g/mL Aztreonam into isolation media to inhibit the other bacteria and 20?g/mL Benlete to inhibit fungi.We used fluorescent in situ hybridization to identi 1fy Actinobacteria. Using the four probes,PA-1,PA-2,PHGC and PNHGC,we made the identification on the 31 strains of the 56 gram-positive bacteria randomly selected and got 22 positive results,6 negative results and 3 ambiguous results.It was showed that the results of G+C content determination and FISH method were identical.Among 31 strain,there were 24 strains of Actinobacteria,the rate was 77.4%.This proved the isolation and FISH identification methods were effective and reliable.
