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.

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.

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 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.

Background Retinal Müller cells can offer nutrient and maintain the normal structure of retina.Researches showed that the abnormality of Müiller cells leads to retinal vascular disease.To explore the effect of high glaucoma on retinal Müller cells is of a very important significance for the study on diabetic retinopathy (DR).Objective This study was to investigate the effects of different concentrations of glucose on retinal Müller cells in vitro.Methods Retinal tissue was isolated from 1 10-day-oM clean SD rat.Mtiller cells were cultured by explant culture method and passaged in DMEM containing 20％ fetal bovine serum.The third generation of cells were obtained and identified using glial fibrillary acidic protein (GFAP) staning.Then,5.5,30.0 and 40.0 mmol/L glucose were added into the culture medium for 4 days respectively.The proliferation (A570) of Müller cells was detected by MTT,and apoptosis rate of Müller cells was calculated by flow cytometer to evaluate the effects of 5.5,30.0 and 40.0 mmol/L glucose to cell vitality.Results Cultured and passaged cells grew well with the spindle shape.The positive reactive cells were ＞95％ for GFAP.The A570 value of Müller cells was 0.24±0.01,0.21±0.03 and 0.20±0.02 in 5.5,30.0 and 40.0 mmol/L glucose group respectively,showing a significant difference among the three groups(F=6.755,P＜0.05).Compared with 5.5 mmol/L glucose group,As70 values were significantly lower in 30.0and 40.0 mmol/L glucose group (q =0.645,0.486,P ＜ 0.05).Apoptosis rates of Miiller cells were (26.40 ±0.25)％,(30.19±0.16)％ and (36.23±0.19)％ in 5.5,30.0 and 40.0mmol/L glucose groups,with a significant difference among them (F =294.530,P＜0.05),and those in 30.0 and 40.0 mmol/L glucose groups were significantly reduced in comparison with 40.0 mmol/L glucose group (q =0.754,0.484,P ＜ 0.05).Conclusions High concentration of glucose inhibits the viability and promote the apoptosis of retinal Müller cells at a concentrationdependent manner.

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.

Switching Mechanism At 5′ end of the RNA Transcript(SMART)is a technology used in biology researching,So far,there is no review only about SMART technology.So,the aim is to investigate the research developments of principles,methods and applications of the SMART technology.Based on some researches and combined with the review of the related literature at home and abroad,it analyzed and evaluated the latest development of the research on SMART.As the applications of the SMART technology expand in many fields day after day,it has been proved that the SMART technology is a very useful and efficient skill to construct full length cDNA library.As more and more researchers know this technology,the advantages of the SMART technology become obvious,and meanwhile the disadvantages of the SMART technology also show up.That is to say,the technology needed to be improved.
