Objective To explore the correlation of anti-ganglioside antibodies with clinical features of systemic lupus erythematosus (SLE). Methods Samples of serum were collected from 48 patients with SLE. Three were male and 45 were female. Their average age was 33±12 (15～59). The serum anti-ganglioside antibodies of 10 patients with rheumatoid arthritis (RA), 4 with Sj(o)gren's syndrome (SS), 1 patient with mixed connective tissue disease (MCTD), 1 with polymyositis (PM), and 97 healthy controls(HC) were alsoexamined. Levels of anti-GM1-IgM/IgG, anti-GQ1b-IgM/IgG antibodies in the serum were examined by amodified ELISA. Anti-dsDNA-IgG antibody of SLE was tested according to the ELISA kit protocol. The associations of anti-GM1-IgM/IgG and anti-GQ1b-IgM/IgG antibodies with clinical features were analyzed. x2test, one-way ANOVA, Dunnett t-test were used for statistical analysis. Results By using modified ELISA,the upper limit of reference value of anti-GM1-IgM/IgG antibodies, anti -GQ1b-IgM/IgG antibodies in the serum of Chinese SLE patients were 0.411, 0.408, 0.481 and 0.441 res-pectively. 19% patients with SLE were sero-positive for anti-GM1 antibody, 4% for IgM antibody isotype and 15% for IgG antibody isotype. Anti-GM1-IgG antibody was significantly increased in the serum of patients with SLE (0.33±0.09), higher than that of the HC (0.27±0.05) (P<0.05), RA (0.29±0.08), SS(0.27±0.06), PM ( 0.288 ), but one of the MCTD( 0.423 ).There was no significant associations between anti-GM1-IgM/IgG, anti-GQ1b-IgM/IgG antibodies and NPSLE and anti-dsDNA-IgG antibody (P>0.05). Conclusion Peripheral autoimmune response against GM1 can be detected in SLE patients, and it may be involved in the pathogenesis of SLE. No association of antiGM1-IgM/IgG antibodies or anti-GQ1b-IgM/IgG antibodies with clinical features of SLE can be discovered.

Objective To explore the plasma ghrelin levels in children and adolescents with short stature and the role of ghrelin in growth hormone-releasing hormone-growth hormone(GHRH-GH) axis.Methods One hundred and fifty-seven children(115 male,42 female) with short stature were selected.Fasting plasma sample was extracted from 10 mL vemous blood of the children with short stature.Insulin tolerance test and arginine stimulation test was performed initially to differential diagnosis.And blood samples was divided into 3 ca-tegories:37 cases of complete growth hormone deficiency (CGHD),52 cases of partial growth hormone deficiency(PGHD) and 68 cases of idiopathic short stature(ISS) during these two growth hormone(GH)provocative tests.Controls consisted of age and gender-match 20 health children.Plasma ghrelin levels were measured by radioimmunoassay.Serum GH was detected by chemiluminescence method,and serum insulin-like growth factor-1 (IGF-1) was measured by using enzyme linked immunosorbent assay.Fasting glucose,insulin,testosterone,estra-diol,luteinizing hormone,follicle-stimulating hormone were measured.Statistical analysis were conducted by using SPSS 11.5 software.Results The fasting ghrelin levels of CGHD group were significantly lower than that of ISS group and control group(Pa0.05).The ghrelin levels were positive correlated with the stimulated GH peak(r=0.176 P0.05).Conclusion Ghrelin has an important role on GH secretion and abnormal secretion of ghrelin might be a reason of growth hormone deficiency which due to hypothalamic abnormality.

Objective To evaluate the methods and consequences of surgical technique in the treatment of Stanford A aortic dissection.Methods 108 patients with type Standford A aortic dissection underwent surgery in our study,including urgent surgery in 53 and selective surgery in 55.The operation was performed under deep hypothennic circulatory arrest (DHCA) in 85 cases.Surgical procedures included ascending and semi arch replacement or total arch replacement (some cases combined with stented graft implanted into the descending aorta),"elephant trunk" procedure.Concomitant procedures included repair of intimal tear in arch or descending aorta,Bentall procedure,aortic valve replacement,Cabrol or modified Cabrol procedure,aortic valvuloplasty,mitral valvuloplasty or mitral valve replacement,tricuspid valvuloplasty and CABG.Results In-hospital mortality was 6.5% (7 of 108 patients).The mor- tality was 7.5% (4 of 53 patients) in urgent surgery group and in elective surgery group was 5.4% (3 of 55 patients).Ninety six percent survived patients were followed up for 1 month to 13.3 years [mean (3.2?1.3) years] and 2 deaths occurred during the fel- low-up period.3 patients underwent re-operatian.Conclusion The choice of surgical procedures depend on the location of intimal tear for Stanford A aortic dissection.The better operative effects can be expected with proper surgical indication,perfecting surgical technique,and enhancing postoperative treatment.

OBJECTIVETo evaluate the early and mid-term outcome of surgical repair for post-ductal coarctation of the aorta (CoA) under normothermia without cardiopulmonary bypass.

METHODSClinical data from 15 patients (11 males, 4 females, mean age 18 +/- 10 years) undergoing surgical repair for post-ductal CoA under normothermia without cardiopulmonary bypass between January 1999 and December 2004 were analyzed retrospectively. There were 7 isolated cases, 7 cases associated with patent ductus arterious (PDA), 1 case with PDA and ventricular septal defects. Operation was performed under normothermia with partial cross-clamping of descending aorta in 8 cases, compete cross-clamping in 6 cases and temporary shunt in 1 case. Operative techniques adopted prosthetic bypass graft in 9 cases, Gore-Tex patch graft aortoplasty in 4 cases and stenosis resection with end-to-end anastomosis in 2 cases. PDA was ligated at single-stage in 8 cases. Ventricular septal defect was repaired at second stage in 1 case.

RESULTSNo early and late death. Hypertension occurred in 9 cases during early postoperative period but was normalized gradually in 5 cases without medication during follow-up period, from 6 months to 5 years. The arterial blood pressure of lower extremities increased significantly and no hoarseness, paraplegia occurred after operation. No recoarctation and aneurysm formation were found during follow-up.

CONCLUSIONSurgical repair of post-ductal CoA under normothermia without cardiopulmonary bypass is safe and effective, which is a procedure of choice for patients with isolated CoA, CoA associated with PDA, or with other intracardiac anomalies that are ready to be repaired at second-stage.

OBJECTIVETo analyze the clinicopathological features and prognosis of colorectal cancer patients with preoperative cancer-related anemia.

METHODSClinical data of 354 patients with colorectal cancer in the Second Affiliated Hospital of Guangzhou Medical College from January 2003 to July 2009 were analyzed retrospectively. Those with hemoglobin(Hb)<120 g/L before surgery were defined as cancer-related anemia.

RESULTSOf the 354 colorectal cancer cases, 195 were males and 159 were females. The median age was 65(range 22-92) years. Preoperative cancer-related anemia tended to be occurred in female(P<0.01) and those with preoperative albumin ≤35 g/L (P<0.01), right colon cancer(P<0.01) and full-thickness invasion(P<0.05). Cox regression analysis showed preoperative cancer-related anemia was an independent unfavorable factor for overall survival (HR=1.60, 95% CI:1.05-2.44; P<0.05), but not for disease-free survival (HR=1.43, 95% CI:0.97-2.12; P>0.05) in colorectal cancer.

CONCLUSIONSPreoperative cancer-related anemia plays an important role in the development and prognosis of colorectal cancer and great attention should be paid to clinical practice.
