The blood vessels supplying the anterior part of the iliac crest of 126 (84 males, 42 females) Chinese adult cadavers were observed. The findings are as following:1. The superficial circumflex iliac artery has an average external diameter of 1.45?0.41 mm and supplies mainly the skin and the superficial structures of the groin region and the region adjacent to the anterior superior iliac spine.2. The ascending branch of the lateral circumflex femoral artery has an average external diameter of 2.62?0.51 mm and supplies the tensor fasciae latae and the outer border of the anterior superior iliac spine.3. The deep upper branch of the superior gluteal artery has an average external diameter of 2.87?0.56 mm and supplies the glutei medius et minimus and the outer border of the anterior part of the iliac crest.4. The deep circumflex iliac artery has an average external diameter of 2.77?0.47 mm and may originate from above (18.0％), behind (41.5％), or below (40.5％) the inguinal ligament. It supplies the abdominal muscles adjacent to iliac crest and the inner border of the anterior part of the iliac crest.In this study particular attention was paid to investigating the course, branches, anastomosis of the deep circumflex iliac artery and its relationship to the anterior part of the iliac crest.5. The findings suggest that the deep circumflex iliac vessel may be used as a nutritive pedicle in free microvascular transplantation of the iliac bone.

Morphology and relationships of piriformis and its tendon,and their relations withsciatic nerve in 100 cases have been observed in order to analyse the cause of sciatica.Piriformis was divided into four types and piriformis tendon into five types.In79% of piriformis there were additional origins.In 5% of cases synovial bursa waspresent below the end of piriformis tendon.The relation between piriformis andsciatic nerve was anomalous in 38%.Sciatic nerves and their branches in 16%passed between the two tendons of piriformis,and along the anterior or posteriorsurface of a tendon.It is concluded that various anomalous relationship between piriformis tendonand sciatic nerve is an important factor giving rise to sciatic pain.

Objective To find out common allergens in Rizhao by investigating the allergens in patients with allergic rhinitis.Method The allergens in 686 patients with allergic rhinitis in Rizhao were detected by skin prick test.Results 509 of 686(74.20%)cases presented positive reaction,in which,the positive rate was 70.99%in inhalation group and 30.61%in food group,the most common inhalation allergen was pteronyssinus,then was dermatophagoides farinae,cockroaches;The most common food allergen was the jellyfish,then was peaches,peanuts.Conclusion The inhaled allergens were the main risk factors for allergic rhinitis,in which,mites was the most common allergens.

Objectives To explore the clinical features of incomplete Kawasaki disease (IKD) which presents with sterile pyuria in infant, in order to achieve early diagnosis and treatment. Methods A retrospective study of 15 infants with IKD was conducted in comparison with 29 patients who were diagnosed with KD according to the diagnostic criteria of American Heart Association 2004. Results Both KD and IKD groups had recurrent fever and poor response to antibiotic therapy. Hemoglobin level was signiifcantly lower in IKD group than in KD group at the onset or 7-d after onset (P<0.05). C-reaction protein (CRP) level was signiifcantly higher in IKD group than that in KD group at 7-d after onset (P<0.05). There were 4 patients with coronary artery abnormality, 2 patients with coronary artery dilation and 2 patients with coro-nary artery aneurysm. Conclusions For infant <1 year old who has pyuria ifrstly, continuous fever for over 5 days when treated by antibiotics and increasing serum inlfammatory markers, incomplete Kawasaki disease should be suspected and the cardiac ultrasound is recommended.

Background Rare studies on the effect of statin on early stage of atherosclerosis have been repor- ted.Oxidative stress induced endothelial dysfunction may be the initiative factor for the development of atheroscle- rotic plague.Objective To investigate the mechanisms by which simvastatin,prevents atheroselerosis independ- ently of its lipid-lowering effect in Apolipoprotein E deficient mice.Methods Twenty-four 6 week old male apoE- deficient mice were randomly to receive placebo or simvastatin 5 mg/(kg?d)by gavage for 4 weeks.Total choles- terol(TC),super oxide dismutase(SOD),malondialdehyde(MDA)and serum nitric oxide(NO)were measured by biochemical analysis.Endothelium was observed by HE dyeing.The expression of caveolin-1 in aortic wall was detected by immunohistochemistry.Results There was no significant difference in serum TC between control and simvastatin treatment groups.Simvastatin caused less damaged endothelium(33.33% vs control's:75%,P

Aim To ascertain whether defibrase has the protective effect against reperfusion injury after cerebral ischemia.Methods 70 renovascular hypertensive rats(RHR) were randomly divided into defibrase group, control group and sham-operated group.Reversible middle cerebral artery occlusion(MCAO) models were produced by the modified. Longa's method,and reperfusion was begun 2 hours after occlusion.Rats in the defibrase group were given defibrase 10 U?kg-1 body weight via femonal intraveneous injection, and in the control group with the same amount of saline. The brain pieces were processed by TTC and HE staining and the infarct size,brain microvessels damage and secondary bleeding were compared between the two groups. Results The volume of infarction in the defibrase group was obviously smaller than in the control group, the damage of brain microvessels was less severe, and the bleeding lesions under optical microscope were less than in the control group. Conclusion Defibrase has protective effect against reperfusion injury post cerebral ischemia.

To study the chemical constituents of the inflorescences of Coreopsis tinctoria from Xinjiang, isolation and purification of constituents were carried out by column chromatography on macroporous resin (D101) , MCI gel, MDS gel, silica gel, Sephadex LH-20 and semi-preparative HPLC. The structures of the compounds were identified by physicchemical properties and spectral data analysis. Fourteen compounds were isolated and identified as coretinterpenoid A (1), coretinphenol (2), quercetin (3), quercetin-3-O-β-glucopyranoside (4), luteolin (5), taxifolin (6), 7, 3', 5'-trihydroxyflavanone (7), isookanin (8), isookanin-7-O-β-D-glucopyranoside (9), 5, 7, 3', 5'-tetrahydroxyflavanone-7-O-β-D-glucopyranoside (10), butein (11), okanin (12), sulfuretin (13), and linocinnamarin (14). Compound 1 was a new isabolane-type sesquiterpenoid and compounds 4, 10 and 13 were isolated from this plant for the first time.

Objective To explore the efficacy of mycophenolate mofetil-based induction or maintenance therapy for children with lupus nephritis combined with Calcineurin inhibitors (cyclosporine A/tacrolimus) for resistant cases.Methods the clinical data were analyzed for 10 patients treated with multi-target therapy (Glucocorticoid + Mycophenolate mofetile+ Cyclosporine A/Tacrolimus) in Department of Nephrology and Rheumatology from January 2005 to December 2011.Calcineurin inhibitor (Cyclosporine A/Tacrolimus) was added when Mycophenolate mofetil-based induction or maintenance protocol was not satisfactory.The data was analyzed by repeated measures data of ANOVA.Results The SLEDAI score (10.9±3.8 vs 7.9±2.6),24 hours urinary protein quantification [(4.0±2.0) vs (2.2±1.8) g] and ESR [(78±10) vs (54±8) mm/l h] were decreased significantly (P＜0.01),while serum albumin [(29±8) vs (34±8) g/L] and complement C3 level [(0.41±0.20) vs (0.70±0.30) g/L] were increased significantly (P＜0.05).The complete remission rate (CR) was 70％ and the response rate was 90％ in the first 6 month,and the CR was 90％ in the last month.Except 1 case withdrawal,the follow-up period for 9 cases was 24 months.Adverse reactions were rare,1 case had lung in-fection,1 case had hyperglycemia and 1 case had transaminase elevation,which disappeared after mana-gement.Conclusion Mycophenolate mofetil combined with Calcineurin inhibitors (cyclosporine A/tacrolimus) is effective for treating lupus nephritis,the dose of induction or maintenance period is low,and adverse reactions are rare.
