The endoluminal stenting is popular for more than two decades,even in China,encouraging achievements also are getting around the recent dacade.Endoluminal stents are not only applicated for all kinds of vascular stenosis,and nonvascular stenosis such as biliary tract,esophagus,trachea etc,but also are utilized gradually in the interventional treatment of cerebral ischemia and hemorrage in the recent years,especially for aortic aneurysm.There would still have a long way to go in China for further development in basic research,standardized procedure,and normalized followed-up.The main target for all the interventional radiologists in the foreseen future is how to develop new stents with independent knowlege property right and to expand the stents usage reasonably.

Livedoid vasculitis is a kind of skin disease caused by local vascular occlusion.It mainly manifests as erythematous and purpuric maculas or papules on the legs and ankles,which may progress into intensely painful ulcers and heal leaving porcelain-white atrophic scars called atrophie blanche.Histopathologically,inflammatory response is weak or absent in local lesions of livedoid vasculitis,hence,it is commonly considered to be related to local thrombosis and other autoimmune diseases.Now,it is mainly managed with anticoagulation-based comprehensive treatment in clinic.

Objective: To observe the clinical efficacy of acupuncture plus auricular point sticking for tension-type headache (TTH). Methods: A total of 90 TTH patients were divided into an acupuncture group, an auricular point sticking group and an observation group by random number table method, with 30 cases in each group. Patients in the observation group received acupuncture plus auricular point sticking for treatment, while those in the acupuncture group only received acupuncture and those in the auricular point sticking group only received auricular point sticking for treatment. The headache attack frequency and the scores of visual analog scale (VAS), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were observed before treatment, after treatment and 3 months after treatment. The clinical efficacy was evaluated at the follow-up of 3 months after treatment. Results: At follow-up, there were significant differences in clinical efficacy among the three groups (P<0.01 or P<0.05), and the clinical efficacy ranking from high to low was the observation group, the acupuncture group and the auricular point sticking group. After treatment and at follow-up, the VAS score, headache attack frequency, SAS and SDS scores in the three groups were significantly lower than those before treatment (all P<0.01). The above four results in the observation group were lower than those in the acupuncture group and the auricular point sticking group at the same time point (all P<0.01); VAS score in the acupuncture group was lower than that in the auricular point sticking group (both P<0.05). At follow-up, the headache frequency in the acupuncture group was lower than that in the auricular point sticking group (P<0.05). Conclusion: Either using acupuncture and auricular point sticking together or separately can reduce the headache degree of TTH patients, reduce the number of headache attacks, and relieve anxiety and depression. The efficacy of acupuncture plus auricular point sticking is most significant.

Objective To observe the changes of four quantitative indexes of diabetic macular edema by using optical coherence tomography.Methods Eighty-nine patients (155 eyes) with diabetic retinopathy were included in this project and were divided into two groups according to the present of diabetic macular edema:Negative group (56 cases,100 eyes) and positive group(33 cases,55 eyes).In addition,23 cases (42 eyes) of normal volunteers constituted the normal control group.All the objects accepted an optical coherence tomography examination and the indexes including central retinal thickness (CRT),subfoveal choroidal thickness (SFCT) and integrity of external limiting membrane(ELM) as well as inner/outer segment (IS/OS) were measured and analyzed.Results The average CRT of positive group (219.048 ± 16.798) μm was significantly thicker than that of control group(217.775 ± 26.866) μm and negative group (280.418 ±74.187) μm (P ＜0.001).Mean SFCT among control group (312.893 ±140.559) μm,negative group (302.080 ± 125.287) μm and positive group (293.745 ±140.517) μm had no statistical significance (P =0.781).There were 3 eyes with disrupted ELM layer in the negative group and 8 eyes in the positive group.Difference between them was proved to be significant (P =0.019).Similarly,the integrity of IS/OS layer had significant difference between negative group (5 eyes disrupted) and positive group (19 eyes disrupted) (P ＜ 0.001).Conelusion CRT of patients with diabetic macular edema is always increased and the integrity of ELM or (and) IS/OS can be disrupted in many cases.Indexes including CRT and the integrity of ELM or (and) IS/OS can be used to evaluate the severity of diabetic macular edema quantificationally.

Objective To investigate the effects of Buyang-Huanwu decoction combined with western medicine on early diabetic renal injury.Methods 200 cases of early diabetic renal injury were randomly recruited into study group and control group,with 100 cases in each group.The control group was treated with insulin injection and oral benazepril hydrochloride,and the blood pressure,blood lipid changes were closely monitored; while the study group was additionally treated with Buyang-Huanwu decoction on the basis of the control group.Results The total therapeutic effects in the study group was significantly higher than the control group (x2=15.62,P＜0.01).The values of FBG,2 h PG,DBP,SBP,HbAlc in both groups were significantly reduced after the treatment (P＜0.05,t=4.23,4.47,3.59,3.87,3.99 in the study group,t=4.34,4.76,4.05,3.78,3.69 in the control group) ; but the difference between the two groups had no significance (P＞0.05).Before treatment rnALB,Urea,Cr,TG and TC were not significantly different (P＞0.05) ; the values of mALB,Ureaand Cr were significantly reduced in the study group after the treatment (P＜0.05,t=4.56,3.73,3.28);especially mALB in the study group was obviously lower than the control group (P＜0.05,t=5.01).Conclusion Buyang-Huanwu decoction combined with western medicine was effective to treat early renal damage of type 2 diabetes,with the functions of reducing urinary protein,improving microcirculation and protecting renal function.

Some problems were settled in making permanent slide for predacious nematode fungi by slide cultivation and cotton blue stain. Method of small-hole culture covered with slides could obtain high quality images, which solved the problem that trapping device couldn't be observed with high-power microscopes and oil-immersion microscopes. Scraping slide technique improved the method of making temporary slides.
