Objective To explore the diagnosis and treatment of abdominal cocoon. Methods This article retrospectively summarized clinical data of 6 cases of abdominal cocoon. Results All the 6 cases of abdominal cocoon were misdiagnosed preoperatively: 5 cases were diagnosed as having intestinal obstruction and 1 case,abdominal mass.Partial or total capsule resection was adopted in all the 6 cases,1 of which simultaneously underwent intestinal arrangement. Conclusions Abdominal cocoon is not specific,which is difficult to diagnose preoperatively.Upper digestive tract radiography,B-ultrasonography and CT scanning help to make the diagnosis.Partial or total capsule resection,intestinal arrangement,intestinal resection and release for intestinal adhesion are usually adopted as the treatment.

Objective To observe the effect of anxiety and depression on cell adhesion molecules and fibrolytic activity in cardiac-pacing patients. Methods The levels of plasma P-selectin, E-selectin, sICAM-1, vWF and PAI-1 were measured in 39 cardiac-pacing patients with anxiety or depression as rersearch group, 32 cases cardiac-pacing patients without any psychological problems as observation control group and 20 healthy subjects as normal control group. Result The levels of plasma P-selectin, E-selectin, sICAM-1, vWF and PAI-1 in cardiac-pacing patients were significantly higher than those in normal control group, and their plasma levels in the patients with anxiety or depression were significantly higher than those in the patients without psychological problems. Conclusion There were significantly elevated cell adhesion molecules level and decreased fibrolytic activity in cardiac-pacing patients.

TUNEL assay was used to detect the apoptosis of tumor in two groups with or without preoperative interventional treatment. The expressions of P53, Bcl-2 and Bax proteins were detected by immunochemical methods. The patients were followed-up for more than 2 years.RESULTS: The extent of neoplastic cell necrosis and degeneration, interstital fiber tissue hyperplasia of tumor and the number of infiltrating lymphocytes were observed, which were higher in interventional group than those in simple excision group (P

Objective To explore whether the polymorphism of human frizzled 3 (rs2241802 ,rs2323019,rs352203) is associated with schizophrenia in Yunnan Han population. Methods PCR-RELP was used to detect the polymorphism of human frizzled 3 (rs2241802 ,rs2323019, rs352203 ) in 153 patients and 100 controls. All patients were evaluated with positive and negative symptom scale(PANSS). Following a linkage disequilibrium test in the 3 loci ,association analysis was carried out between the polymorphism, including haplotype,and schizophrenia in all samples. Results No significant difference of genotype and allele frequency of the 3 loci were observed in 2 groups. There was no difference in genotype and allele frequency of rs2241802 ,rs2323019,rs352203 in Han samples (P＞0.05) . The polymorphisms of the 3 loci had been observed no difference in case-sibling control study of normal group. A-A-C haplotype and G-A-C haplotype were observed with a higher frequency in both samples (P＜0.05). There was no difference in patients and controls in PANSS scores (P ＞ 0.05 ). Conclusions There is no association between polymorphisms of human frizzled 3 ( rs2241802, rs2323019, rs352203 ) and schizophrenia in Han. A-A-C and G-A-C haplotype might possibly associate with schizophrenia in Yunnan Han population.

Objective To investigate the relationship between C-peptide and artherosclerosis in lower ex-tremity in patients with type 2 diabetes. Methods Two hundred and fourteen type 2 diabetic patients were included in this retrospective study. They were divided into two groups:type 2 diabetes with artherosclerosis in lower extremi-ty in 123 cases and type 2 diabetes without artherosclerosis in lower extremity in 91 cases. Their medical history and the laboratory data were collected such as fasting serum C-peptide levels and postprandial serum C-peptide levels of 1 hour, 2 hours and 3 hours, glycated hemoglobin (HbA1c) and so on. Results Compared with artherosclerosis group in lower extremity, the age, duration of diabetes, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), glycated hemoglobin and smoking rate were significantly higher in type 2 diabetes without artherosclero-sis in lower extremity (P < 0.05). However, the high density lipoprotein cholesterol (HDL-C) was much lower in the last group (P<0.05). There were no significant differences in the other indicators between the two groups (P>0.05). Logistic regression analysis showed that fasting and postprandial (1 hour, 2 hours and 3 hours)serum C-pep-tide levels were all negatively related to artherosclerosis in lower extremity (OR 0.524,P = 0; OR 0.440, P = 0;OR 0.688, P=0;OR 0.795, P=0). Conclusions Serum C-peptide level may be an independent associated fac-tor with artherosclerosis in lower extremity in type 2 diabetes.
