Objective To study the correlation between serum lipids and thyroid function after withdrawn of thyroid hormone in the patients with differentiated thyroid cancer .Methods One hundred and thirty cases of differentiated thyroid carcinoma treated by operative therapy in our hospital form August 2014 to August 2015 were selected .Serum FT4 ,TSH ,FT3 ,triglyceride ,total cho-lesterol ,LDL-C ,HDL-C indexes were detected before discontinuation of levothyroxine sodium (L-T4) ,before operation and 3 weeks after drug withdrawn .Thus the correlation between blood lipid levels and thyroid function was analyzed .Results The HDL-C and the TSH level was positively related before operation (P<0 .05) ,other indexes had no obvious correlation with thyroid function (P>0 .05);the blood lipid levels after medication withdrawn had no obvious correlation with thyroid function (P>0 .05);the total cholesterol levels after medication discontinuation had negative correlation with FT 3 and FT4 levels(P<0 .05);HDL-C was nega-tively correlated with FT3 and FT4 levels(P<0 .05) ,and positively correlated with TSH level (P<0 .05);LDL-C was negatively correlated with FT4 (P<0 .05) .Conclusion When the application treatment of thyroid hormone is suspended ,with the TSH level increase ,the HDL-C level has somewhat elevation ;total cholesterol ,HDL-C and LDL-C levels are negatively correlated with FT 3 and FT4 ,after discontinuation of medication withdrawn ,the blood lipids metabolism abnormality is closely related with thyroid function decline .

Objective To explore the local application of immunosuppressant in improving the survival rate of the transplanted islet cells and systemic side effects.Methods The streptozocin of 200 ms/kg was injected into the abdominal cavity of the Wistar rats，the blood sugar was tested after 48，and 72 hours，and the rats with two consecutive measurements ≥20 mol/L were taken as the experimental animal model.The dose of pancreatic islet cells transplanted into the abdominal cavity was 8 000 IE,/kg，and that of cyclosporine dosage was 1.5 mg/(100 g·d).The pancreatic islet cells were divided into three groups：(1)systemic immunosuppressive agents through stomach lavage with the intraperitoneal injection of microencapsulated islet cells；(2)pure intraperitoneal injection of microencapsulated islet cells；(3)intraperitoneal injection microencapsulated activated carbon particles loaded with immunosuppressants，and mieroencapsulated islet cells.Changes of blood glucose and pathological in rats after transplantation were detected.Results The blood glucose of group 3 and group 1 showed no significant difference(P＞0.05)，as well as compared with group 2(P＞0.05).But the local application of immune agents could prolong the effective time of the islet cells and attenuate the fibrotic extent of the surrounding islets when compared with the control group,the C peptide level in applicating immunosuppressive agents group was significantly hisher in the immunosuppressive group than the pure transplantation group.ConclusionCompared with the systemic immune suppression via stomach lavage，local application of slow-release immunosuppressive agents showed the same effects of activated carbon particles，with a prolonged the effective time of islet cell and reduced topical side effects in the latter.

Objective To research the effect of pure interbody fusion and interbody cage fusion under minimally invasive transforaminal lumbar interbody fusion treat to single segment of lumbar disc herniation,analysis clinical value the two methods.Methods A total of 61 cases single segment lumbar disc herniation were treated with MIS-TLIF surgery,were divided into pure interbody fusion group (group A) and interbody fusion Cage group (group B) according to different fusion methods.Operative time,blood loss and postoperative drainage were recorded in two groups,the clinical efficacy were tested by using of visual analogue score (VAS),Japanese Orthopedic Association scores (JOA),Oswestry disability index (ODI) score and Macnab standard,the interbody fusion ability were evaluated by power lumbar X-ray film and CT 3D reconstruction.Results The gender,age,disease duration and disease segments in two gracps were not found statistically significant difference (P＞0.05).Also,two groups of patients,blood loss,postoperative drainage has no significant difference (P＞0.05).After the operation,the VAS score,ODI score,JOA score and Macnab criteria,the last follow-up of intervertebral fusion rate in in tuo groups were not found statistically significant difference (P＞0.05).While the operative time,postoperative disc height changes were found significant difference between two groups (P＜ 0.05).Conclusion MIS-TLIF simple fusion for lumbar disc herniation will be available with equal clinical efficacy fusion rate compared with cage fusion.
