Objective To report our surgical experience in treating 19 cases of solitary iliac aneurysms (SIA). Methods The clinical data of 19 consecutive patients with SIA between January 1985 and January 2008 were retrospectively reviewed. There were 18 men and 1 woman, aging from 39 to 77 years ( mean 62 ± 7 years). Results There were 30 SIAs in the 19 patients, including 25 ( 83.3% ) common iliac aneurysms, 4 (13.3%) internal ihac aneurysms and 1 (3. 3% ) external iliac aneurysm. Eleven patients ( 57.9% ) had multiple ancurysms, with 9 patients ( 47.4% ) having bilateral SIA. Two patients had coexistent peripheral vascular occlusive disease. There were 2 patients suffering form ruptured SIA, one was saved by emergency operation and one died before an surgery could be attempted. Seventeen patients underwent successful open aneurysmectomy and artificial graft implantation leaving no ischemic complications of the pelvic organs. One patient with right common iliac aneurysm underwent endovascular repair without endoleak. There was no operative death during porioperative period. The surviving patients remained stable and had good patency of grafts during the follow-up period. Conclusions Early management of SIA is important, CT angiogarphy (CTA) is necessary not only to evaluate the SIAs, but also to detect multiple aneurysms or arterial occlusive disease. Close and long-term follow-up is mandatory for the early detection of the formation of new anearysms.

Objective To explore the predictive value of combined ABCD2 scores and tracheal constriction resulted from internal carotid atherosclerosis (ICAS) in cerebral infarction within 7 d of onset of a transient ischemic attack (TIA). Methods The clinical data of 171 patients with TIA,admitted to our hospital from September 2008 to March 2011, were retrospectively analyzed. All patients were evaluated with ABCD2 scale and degrees of tracheal constriction resulted from ICAS were examined by Color Doppler ultrasound.And 7-d follow-up of patients was performed to select those patients appearing cerebral infarction; and then, the relationships between risk of post-TIA cerebral infarction and both ABCD2 scores and degrees of tracheal constriction were analyzed using chi-square test. Results Among 171 TIA patients,39 (22.8％) suffered cerebral infarction within 7 d of onset of TIA.Significant difference of risk of post-TIA cerebral infarction was noted in patients with different ABCD2 scores and degree of tracheal constriction (P＜0.05): the higher the ABCD2 scores/ the degrees of tracheal constriction, the higher incidence of cerebral infarction in TIA patients. Conclusion A rather high accuracy may be achieved with ABCD2 scale in the prediction of short-term risk of cerebral infarction after onset of TIA,and a higher accuracy may be expected by combination of ABCD2 scale with carotid atherosclerosis findings.

BACKGROUNDTakayasu's arteritis (TA) is a chronic idiopathic inflammatory disease that affects large and medium size arteries. The brachiocephalic trunk is the most frequently involved site in TA, and multi-vessel lesions are common. Surgical treatment includes vessel reconstruction surgery and percutaneous transluminal angioplasty (PTA). Herein, we report our preliminary experience with surgical treatment of cerebral ischemia caused by cervical arterial lesions due to TA.

METHODSFrom January 2000 to December 2007, 38 patients with cerebral ischemia caused by cervical arterial occlusive lesions due to TA were treated surgically. There were three males and 35 females, with an age range of 15 - 42 years (mean 26.5 years). All patients had operative repairs undertaken. Twenty eight patients received bypass operation and 10 patients received percutaneous transluminal angioplasty. One case with coronary stenosis received coronary artery bypass simultaneously. Patients were followed up for 11 months to eight years.

RESULTSThere were no peri-operative deaths in cerebrovascular reconstruction patients. Symptoms of cerebral ischemia were improved or cured in 25 of 38 patients. There was a low incidence of cerebral reperfusion syndrome. Two patients died at five and seven years after surgery due to heart failure. Another 8 patients (20%) required further surgery for stenosis (5 patients) or anastomotic aneurysms (3 patients). Percutaneous transluminal angioplasty was performed successfully for treatment of aortic and renal lesions. Repeated angioplasty for revascularization was performed in six PTA cases with restenosis after 5 - 24 months.

CONCLUSIONSWhen cerebral perfusion has potential to be affected by TA, a definitive corrective procedure is advised when the patient is relatively stable. Although the recurrence rate is very high, percutaneous transluminal angioplasty is the first choice procedure. Bypass operation is optimal for brachiocephalic-vessel involvement in TA. Cerebral reperfusion syndrome can be avoided by careful selection of the operation method and improved post-operative treatment.

Objective:To explore the clinical value of detecting serum 14-3-3η and auto-antibodies in rheumatoid arthritis (RA),and compare their performance in RA diagnosis.Methods: Serum samples of 134 RA patients,90 non-RA inflammatory arthropathy patients,70 of whom with osteoarthritis(OA)and 20 with ankylosing spondylitis(AS),and 40 healthy controls from the second affiliated hospital of Nanchang University were collected.Concentrations of 14-3-3η,anti-CCP,anti-RA33,anti-Sa were detected with enzyme linked immunosorbent assay(ELISA),with RF detected by immunonephelometry.Diagnostic utilities of them for RA were evaluated and compared then.Results:① Serum levels of 14-3-3η,anti-CCP,anti-RA33,anti-Sa and RF were significantly higher in patients with RA than non-RA inflammatory arthropathy patients and healthy controls,the differences between groups were statistically significant;② ROC curves were conducted according to the serum levels detected.The AUC of 14-3-3η,anti-CCP,anti-RA33,anti-Sa and RF were 0.831(95% CI:0.782-0.881),0.852(95% CI:0.802-0.901),0.615(95% CI:0.546-0.684),0.706(95% CI:0.643-0.770)and 0.739(95% CI:0.676-0.802)respectively,with P values<0.01.Among all index,only anti-CCP and 14-3-3η were of moderate diagnostic value,at the threshold of 24.10 U/ml and 2.59 ng/ml individually;③anti-Sa was of highest specificity and RF was of highest sensitivity among all indexes detected;the specificity of 14-3-3η was merely moderately inferior to anti-Sa and anti-RA33,but its sensitivity was superior to them both.Conclusion:Serume14-3-3η,anti-CCP,anti-RA33,anti-Sa and RF levels increased remarkably in patients with RA,and contributed to RA diagnosis.Meanwhile,14-3-3η was advantageous,to some extent,in the sensitivity and specificity over auto-antibodies,and can be utilized as a reference index in diagnosing RA.

OBJECTIVETo investigate the expressions of 78-kDa glucose-regulated protein (GRP78) and Caspase-12 and their relationship with apoptosis in renal cortex of diabetic rats.

METHODSUninephrectomized Wistar rats were used to induce diabetes by intraperitoneal injection of Streptozotocin (STZ 65 mg/kg). After 8 weeks, the expression and distribution of GRP78, Caspase-12, proliferating cell nuclear antigen (PCNA) were examined by immunohistochemistry. Flow cytometry was used to detect the levels of protein of GRP78 and Caspase-12. Apoptosis was evaluated by means of terminal deoxynucleotidyl transferase-mediated d-UDP nick-end labeling (TUNEL) and Flow cytometry. Serum creatinine, blood urea nitrogen and 24-hour urine protein excretion were checked.

RESULTSCompared with those in normal control group, the numbers of apoptosis and the expression of GRP78, Caspase-12 in glomerular and tubular cells were much higher in the diabetic kidneys at 8 weeks. There was no significant difference between group A and group B.

CONCLUSIONActivation of endoplasmic reticulum stress may play an important role in the development of diabetic nephropathy.
