Objective To explore the clinical significance of dyslipidemia in patients with systemic lupus erythematosus (SLE).Methods By independent-samples t test,serum lipid level was compared between 326 SLE patients and 300 healthy controls.The total cholesterol (TC),triglyceride (TG),lowdensity lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were partially compared in subgroups of SLE patients.The correlation of serum TC,TG,LDL-C and HDL-C with clinical manifestations and laboratory findings in SLE was analyzed by Pearson or Spearman correlation analysis.Results ①The serum levels of TC [(3.8±1.5) mmol/L],TG [(2.1±1.6) mmol/L] and LDL-C [(2.1±0.9) mmol/L] were significantly higher in SLE group than those of the control group [(3.4±0.6),(0.8±0.4),(1.9± 0.5) mmol/L],and the serum level of HDL-C [(1.2±0.9) mmol/L] was significantly lower in SLE group than that of the control group [(2.0±0.5) mmolFL] (t=4.953,P=0.000; t=14.569,P=0.000; t=3.204,P=0.001; t=-14.335,P=0.000].② The serum levels of TC [(4.0± 1.7) mmol/L],TG [(2.5± 1.7) mmol/L] and LDL-C [(2.2±1.0) mmol/L] were significantly higher in LN group than those of the non-LN group [(3.6±1.0),(1.6± 1.0),(1.9±0.7) mmol/L; t=2.646,P=0.009; t=6.292,P=0.000; t=3.261,P=0.001].③ The serum level of TG [(2.2±1.6) vs (1.8±1.4) mmol/L] was significantly higher in SLE patients with hypocomplementemia than that of the normal ones (t =2.098,P=0.038).The serum level of HDL-C [(1.1 ±0.4) vs (1.6± 1.7) mmol/L] was significantly lower in SLE patients with hypocomplementemia than that of the normal ones (t=-2.375,P=0.020).④ The serum level of TG [(2.3±1.7) vs (2.0±1.4) mmol/L] was significantly higher in anti-dsDNA antibody positive patients than that of negative ones (t=1.989,P=0.048).The serum level of HDL-C [(1.5± 0.4) vs (1.4±1.2) mmol/L] was significantly lower in anti-dsDNA antibody positive patients than that of negative ones (t=-2.979,P=0.003).⑤ The lipid level was correlated with the clinical manifestations and laboratory findings in SLE patients.Conclusion Dyslipidemia exists in patients with SLE and has close correlation with LN,hypocomplementemia and positive anti-dsDNA antibody.

Objective To study the methods for diagnosis and treatment of insulinoma.Methods The clinical data of 120 patients with insulinoma who had been admitted to our hospital in the last 40 years were retrospectively reviewed.Results Fasting blood glucose values were less than 2.75 mmol/L in all the patients.Fasting serum insulin values in 75 patients were higher than 25 ?U/mL,and the average was (65 ?6.0)?U/mL.Before operation,tumor was detected in 2 of 60 patients by ultrasound scan,and in 10 of 50 by CT. Among 18 patients who had intra-operative B-ultrasound examination, 16 positive cases were verified by intraoperative exploration; and one case the tumor was not palpable but was found by intraoperative B-ultrasound examination.The operations included enucleation of insulinoma(70 patients),insulinoma resection and distal resection of the pancreas(44),distal resection of the pancreas(4),and biopsy(2).The low blood glucose symptoms disappeared after the first operation in 111 of the 112 patients who had benign tumor.One case with benign tumor was cured by a second operation.Twenty patients developed pancreatic fistula after tumor enacleation, of them,14 healed uneventfully after drainage,5 were cured by operation,and 1 died of peritoneal infection.Conclusions Preoperative localization of insulinomas is difficult. Intraoperative exploration and ultrasound scan are the chief methods for the localization of insulinoma.Enucleation of insulinoma should be selected for benign tumor. Resections of the pancreatic body and tail is required for large,deep or multiple tumors.

Objective To explore rational surgical treatment for rectal villous adenoma with canceration. Methods Sixty-two cases of rectal villous adenoma with canceration undergoing different surgical procedures were analyzed retrospectively. Among them 28 underwent local excision including 20 with transanal resection and 8 with Kraske resection; Thirty-four underwent extended excision consisted of 11 Miles operation, 21 with Dixon operation and 2 with other procedures. Results Among 62 cases, 82%(51/62)were in early stage. 68%(42/62) and 26%(16/62) of the patients were of high and middle differentiation in pathology respectively. Six cases suffered from recurrence or metastasis in both local and extended excision groups. The 5-year survival rate after local and extended excision were 79% and 76% respectively. Conclusions Most rectal villous adenomas with malignant change were less invasive; Prudent selection of surgical modality is both effective and less dangerous for the treatment of this entity.

Objective To summarize the experience in the diagnosis and management of insulinoma. Methods From January 1966 to December 2007, the clinical data of 131 patients with insulinoma were retrospectively analyzed. Results All the 131 cases had Whipple triad syndrome and 64 eases suffered from psychoneurosis symptoms. The fasting blood glucose or insultus blood glucose concentration of all the cases was lower than 2.8 mmol/L. The ratios of serum insulin to glucose were all higher than 0.3. Before operation, tumor was detected in 8 of 75 patients by B-us scan, and in 17 of 68 by CT, and in 5 of 10 by MRI. The intraoperative ultrasonography(IOUS) was applied in 44 eases, and tumor was found in 43 cases. Surgery included enucleation of insulinoma (88 cases), resection of the corpus and eauda of the pancreas (40 cases), duodenopancreatectomy (2 cases), and biopsy (1 case). The low blood glucose symptoms disappeared postoperatively in 130 cases. Pancreatic fistulae occurred in 20 cases, acute pancreatitis occurred in 32 cases. Conclusions Insulinoma can be diagnosed based on symptoms of Whipple triad and the ratio of serum insulin to glucose. Exploration and IOUS are the simple and effective methods to localize insulinoma.

Objective To explore the relationship between cardiac involvement and laboratory indicators in patients with rheumatoid arthritis(RA). Methods Cardiac echocardiography and ECG performance of 184 patients with RA were analyzed retrospectively. Results Among the 184 patients with RA, the pulmonary hypertension detection rate was 8. 3%, valvular disease 38. 9%, arteriosclerosis 27. 8%, wall to reduce the exercise 13.9%, myocarditis 5.6% and pericardial effusion 5.6%, according to the echocardiography examinations;Sinus tachycardia was evidenced in 15. 22% patients, ST-T changes in 39. 13%, electric axis left side in 8. 70%, branch block in 13.04%, left ventricular hypertrophy in 4. 35%, atrial fibrillation in 4. 35%, premature in 8.70%, early repolarization syndrome in 2. 17% and electric-axis right side in 4. 35% patients by ECG examinations. The serum level of CRP (46. 77 ±5. 87) mg/L was significantly higher in RA patients with cardiac involvement than that in the non-cardiac involvement patientsm (28. 45 ±3. 21) mg/L (P ＜0.05) ;While the serum level of ESR,RF,IgG,IgA,IgM, PLT showed no statistically significant differences between the two groups (P ＞ 0.05); Within RA patients withcardiac involvement, the serum level of CRP showed no significant difference among different sub-groups , which were classified according to the echocardiography performance (P ＞ 0.05). Conclusions Cardiac involvement occurred frequently in patients with rheumatoid arthritis. The valvular disease, arteriosclerosis, reducing of the wall motion and pericardial effusion are the main manifestations by echocardiography examination; Sinus tachycardia, ST-T changes,branch block and premature beats are the main ECG abnormalities. The serum level of CRP is significantly higher in RA patients with cardiac involvement than that with non-cardiac involvement patients. The higher level of CRP in patients with RA may indicate the cardiac involvement presence.
