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.

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.

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 shorten the time of drug reception for ward areas and improve the overall satisfaction level towards the hospital. Methods The process of drug reception for ward areas was optimized by means of information technology and through business process reengineering. Results The time of drug reception for ward areas was effectively shortened and work efficiency and the overall satisfaction level were improved. Conclusion Using information technology and implementing business process reengineering are effective measures that can be taken by hospitals to improve efficiency and satisfaction level.

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 discuss the safety issues of moxibustion therapy in view of moxibustion materials. Methods: The analyses and assessment were performed based on the survey carried out on the use of moxa, modem and ancient records, modern studies, and clinical applications. Results:Moxa has been used as both a medicine and a food for a long history in China. Regarding moxibustion specifically, moxa has been proven to be the optimum choice for moxibustion therapy,through practices and experiments by doctors from different generations. No records have shown any side- or adverse-effects of moxa applied in moxibustion therapy. Conclusion: Moxa has been used in multiple ways for several thousands of years by Chinese people. As the main material for moxibustion therapy, its safety has been proven by documents and clinical practices.

Objective: To evaluate the clinical effect of auricular sticking therapy in treating vascular headache. Methods: Fifty patients with vascular headache were randomized into two groups, 25 cases in each. The treatment group received auricular sticking therapy with magnetic pearls, and the control group was treated by Flunarizine Hydrochloride, 30 d as a treatment session, and the results were measured after one treatment session. Result: The total effective rate was 92.0% in the treatment group while 60.0% in the control group, and the difference was significant (P<0.01). A marked decrease of blood pressure was detected in the treatment group (P<0.05). The mean velocity in middle cerebral artery and anterior cerebral artery both changed significantly (P<0.01). Conclusion: Auricular sticking therapy can significantly improve the condition of vascular headache, as well as reduce blood pressure and help cerebral blood flow.

Objective To establish carotid artery bifurcation aneurysm in canine, and to clarify whether specific hemodynamic insult in combination with arterial wall degeneration will lead to the occurrence and development of aneurysms. Methods New bifurcation aneurysm model of common carotid artery (CCA) was successfully established in 18 dogs, which were randomly divided into the elastase-treated bifurcation group (EBG,n=9) and the control bifurcation group (CBG,n=9). Three dogs were treated with elastase insult to both straight sections of CCA and were used as elastase-treated straight section group (ESG,n=3). Angiographic and hemodynamic analysis was conducted immediately after the operation, as well as 12 and 24 weeks after the operation. Histopathological examination was performed 12 and 24 weeks after the operation. Results Angiography showed that new aneurysm (mean diameter 3.2 ±0.4 mm) was formed at the apex of CCA bifurcation in 5 dog models of EBG group, while no new aneurysm was observed in both CBG and ESG groups. In EBG group, no rupture of the new aneurysm occurred during the follow-up period. Histological analysis revealed that in EBG group the inner elastic lamina was discontinued, the elastic fiber was disrupted, the muscle layer became thinned, the smooth muscle cells were reduced, and the inflammatory cell (macrophage) infiltration as well as the expressions of MMP-2 and MMP-9 were increased;these changes were statistically significant when compared with those in CBG group and ESG group (P<0.001). Postoperative hemodynamic analysis indicated that in EBG group the wall shear stress at the apex of CCA bifurcation was reduced, the blood flow velocity was decreased, with the relative and total pressure being the highest;all the above changes returned to normal after arterial wall remodeling. Conclusion The results of this study indicate that the arterial wall degeneration and the hemodynamic effect at the apex of CCA bifurcation can lead to new aneurysm formation in canine model.
