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.

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.

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

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.

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 discuss the midterm results of modular femoral prosthesis in total hip revision surgery for bone defects.Methods From December 2001 to June 2006,by using Link-MP modular femoral prosthesis for muhiple reasons(48 with asepsis loosening,seven with infections using two-stage revision procedure,one with fracture of proximal femur and one with periprosthetie fracture), total hip revision surgery was carried out in 56 eases including 24 males and 32 females with age range of 38-77 years(mean age 58.8years).Causes for revision included sterile prothesis loosening in 48 cases, infection of hip prosthesis in seven and peripheral fracture of femoral stem fracture prosthesis in one.Re- vision for infected femur was all at stageⅡ.Of 56 cases with femoral stem prosthesis loosening,30 had loosening of primary cemented prosthesis and 26 of uncemented prosthesis.According to the Mallory bone defect classification,five eases were with typeⅡbone defect,21 with typeⅢA,28 with typeⅢB and two with typeⅢC.Bone grafting was performed in 12 cases and wire or cable cerelage in 28.Fracture of great trochanter was found in two cases,fracture of femoral stem in three and perforation of femoral stem in one.Results A total of 52 eases half year after operation were followed up for mean 31.78 months (8-56 months).No migration of distal femoral stem was found in all eases except for one ease had 1.5 cm subsidence of proximal femoral stem.The Harris hip score was preoperative 46 scores(21-52)and post- operative 89(79-94).There found no significant limb discrepancy,thigh pain or dislocation.Conclu- sions Total hip revision surgery for femoral bone defect using modular femoral prosthesis has optimal midterm result especially in its advantages of regulating limb length,offset,anteversion,which can help us match the proximal femur with distal femur and achieve initial and long-term stability.
