An indirect ELISA to detect IgM and IgA autoantibodies against liver-specific membrane lipoprotein(anti-LSP)in human sera is described. Human LSP was used as the coated antigen. Serum samples were pre-absorbed by SPA(bacteria)reagent. The results of serial identifications and the detection of 182 patiens with viral hepatitis indicated this procedure was specific, its duplicate was satisfactory, and the method could be valuable for iurther studying the role of anti-LSP in the pathogenesis of viral hepatitis. Key words: ELISA, Liver-specific membrane lipoprotein, Viral hepatitis, IgM, IgA.

Objective To explore the clinical effectiveness and safety of percutaneous vertebral augmentation with the Vessel-X bone void filling container system (Vesselplasty). Methods Three cases of fresh osteoporotic vertebral compression fracture were treated with Vesselplasty. After procedure, the pain relief, the fracture reduction, and the cement distribution in the vertebra were observed. Results All the 3 cases were treated with the unipediclar injection technique. The operative time was 45, 32 and 30 min, respectively. The hemorrhage volume was

The dynamic changes of the contents of polyamines and excitatory amino acid in the hippocampus during cerebral ischemia and reperfusion were observed in rats.It was found that the content of putrescine was increased and the release of excitatory amino acid elevated during reperfusion,and the increase of putrescine could be stopped when the antagonist of NM-DA receptor of excitatory amino acid,that is,MK-801,was administered.These facts suggest that the metabolic disturbance of polyamines in closely related to the release of excitatory amino acid and modulated by NMDA receptors.The combination of polyamines with excitatory amino acid may play an important role in the ischemic damage of the brain.

Objective To evaluate liver transplantation for patients with hepatocellular carcinoma (HCC).Methods From Feb,1999 to Mar,2002 a total of 95 cases underwent liver transplantation(LTX) in our centre, among them there were 23 cases of HCC.SPSS 10 0 software was used to evaluate the risk factors on the tumor recurrence after LTX.Results The tumor recurrence rate was 65% during the period of follow up. The patients' tumor free survival rate at 6 and 12 months was 75 0% and 58 3%, respectively. Multi variants analysis revealed that there was a statistical relationship between pretransplant tumor size and tumor recurrence( P =0 024).Statistical relations between preoperative demograplaic, clinical features and post LTX recurrence were not found.Conclusion Large hepatocellular carcinoma is a relative contraindication for LTX.

Objective Study the expression of endothelin(ET) of ischaemic myocardium in rat. Method Sixty Wistar rats were randomly divided into 5 groups: coronary artery simply-ligated group,drug-pre-treated group(Isoproterenol,Pituitrin),coronary atherosclerotic group,sham-operated group(as control group). The samples were cut at 15min,30min,45min,60min,90min,120min after coronary (left anterior descending) ligation, and stained with HE and strept avidin-biotin enzyme complex(SABC)method. Results The expression of endothelin was observed with light microscope. Ischaemic myocardium showed ET-positive staining at the early stage of acute myocardial ischaemia in different groups and more in the pre-treated group. Conclusion the SABC-ET method may provide a new marker for diagnosing early myocardial ischaemia, which will be helpful in confirming the cause of sudden coronary death(SCD).

Objective To investigate the correlation between the disease activity and the serum levels of anti-nuclear autoantibodies against various nuclear components in the patients with systemic lupus erythematosus (SLE). Methods Two hundred and twenty five SLE patients enrolled from 2000 to 2002 were evaluated retrospectively. All patients fulfilled the ACR 1997 diagnostic criteria for SLE. The patients were divided into three groups according to the disease activity: mild group (Group A), moderate group (Group B)and severe group (Group C), as assessed with SLEDAI score. These cases were also divided into 2 groups according to the serum levels of anti-dsDNA antibody. 52 out of 225 patients were followed up further. Results ①There was no correlation between the serum level of anti-dsDNA antibody and SLEDAI score, and between the serum level of ANA and SLEDAI score in 225 patients. ②The serum level of anti-dsDNA antibody in group C was higher than that in group A or group B (P 0.05). Conclusions A positive correlation between the anti-dsDNA antibody and the disease activity was found in the severe group of SLE, but not found in the mild or moderate group. Although the renal damage was more commonly seen in those with higher level of anti-dsDNA antibody, but there is no correlation between the level of anti-dsDNA antibody and the degree of renal lesion.

Objective To evaluate the advantage of video-assisted mini thoracotomy for patients with esophageal cancer compared with routine open thomcotomy.Methods Perioperative clinical results were compared between 24 csses received VAMT(test group)and 26 cases underwent routine open thoracotomy(control group)during the same period.All the cancer stages were T2-3N0-1M0.Results This study showed that VAMT Was a minimally invasive swgew with shorter operation time(40.0±3.3)min vs.(70.3±3.2)min,P＜0.05)and had less bleeding volume both during and after operation compared to the control group(108.1±15.2)ml V8.(200.1±11.3)ml,(380.8±45.4)ml vs.(780.1±52.2)ml,P＜0.05).No significant differences were observed in the two groups with respect to complication occurrence rate(4.2%vs.19.2%,P＞0.05).Conclusion It is suggested that VAMT is safe,reliable and less invasive in the treatmem of esophagus carcinoma.

Objective To explore the relationship between depression and malnutrition in hospitalized aged patients. Methods The mini nutritional assessment (MNA) table and geriatric depression scale (GDS) were used to investigate the nutritional status and depression of 114hospitalized elderly. Results The prevalence of depression was 62.3% (71 patients), the prevalences of malnutrition and latent malnutrition were 43.9% (50 patients) and 41.2% (47patients) respectively. The prevalence of malnutrition and latent malnutrition was higher in depressive patients than in non-depressive patients. After controlling age, number of illnesses, bed-ridden or not and method of nutrition, the nutritional status was negatively correlated with the grade of depression.Conclusions The prevalence of malnutrition in depressive patients is high and is associated with the grade of depression.

Objective To examine the practicability and security of the LigaSureTM vessel-sealing system in radical gastrcctomy.Methods Seventy patients of stage Ⅰ～Ⅲ gastric cancer undergone radical gastrectomy were analyzed retrospectively.Thirty-five radical gastrectomy were performed with LigaSureTM vessel-sealing system,the other 35 eases were performed without LigaSureTM.The operative duration,volume of intraoperative hemorrhage,and postoperative complications were analyzed.Results There were significant difference in both operative duration[(159.9±24.7)min vs(172.6±23.7)min,P＜0.05]and volume of intraoperative hemorrhage[(335.7±40.3)ml vs(371.7±43.2)ml,P＜0.01].There was no significant difference in the postoperative complications between LigaSureTM group and conventional method group.All patients recovered without severe postoperative complications.Conclusion Radical resection of gastric cancer using LigaSureTM instead of conventional hand tie method appears to he shorten operative duration,decreased volume of intraoperative hemorrhage.And the technique is convenient and safe.
