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

FLIP is a protein containing death domain.Human beings have three subtypes of c-FLIPL,c-FLIPs and c-FLIPR,which can inhibit the apoptosis of a variety of tumor cells.c-FLIPL plays a dual role in the apoptotic signal.The expression level of FLIP not only decides the opening and closing of the apoptosis pathway but also achieve the conversion of cells in the apeptotic signaling and proliferative signaling pathway.The regulation of FLIP's expression is a multi-layered,involving multiple signaling pathways.FLIP will probably become an attractive death receptor signaling target of therapy.

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.

Objective To compare the performance of newly developed Chronic Kidney Disease Epideniology Collaboration (CKD-EPI) equation and Modification of Diet in Renal Disease (MDRD) equation in patients with peripheral arterial diseases (PAD).Methods A total of 841 patients with PAD were enrolled in this retrospective cohort study.Estimated glomerular filtration rate (eGFR), calculated by MDRD and CKD-EPI equation respectively, was analyzed by Spearman correlation analysis, Bland-Altman method and Kappa test for the evaluation of correlation and consistency.Net reclassification improvement (NRI) was adopted to compare the death risk assessment between these two equations.Results Although the eGFR was 4.33 ml· min-1 · (1.73 m2)-1 higher with MDRD equation than with CKD-EPI equation, there were still significant correlation and fine consistency between eGFRMDRD and eGFRCKD-EPI (Kappa: 0.749, r=0.991, P＜0.05).The CKD-EPI equation re-classified 9 (1.1％) patients upward to higher eGFR category and 143 (17.0％) patients downward to lower eGFR category.Besides, the performance of risk assessment for all-cause death was better with CKD-EPI equation than with MDRD equation (NRI=0.059, P ＜ 0.05), which was not the case for cardiovascular death (NRI=0.022, P ＞ 0.05).Conclusions There is no solid evidence suggesting that CKD-EPI equation performs better than MDRD equation.

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.

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.
