This study reported the analysis of plasma phospholipid metabolism of the rats and the pathological biomarkers between the type 2 diabetes model control group (MC) and the normal control group (NC). SD rats were randomly divided into 2 groups: NC and MC. To investigate state of plasma metabolite profiling in normal body, type 2 diabetes mellitus (T2DM) model group using UPLC-Q-TOF/MS which was used as analysis tool in this research. The compounds were identified by UPLC-Q-TOF/MS based on MS/MS fragment ions information, element composition in MassLynx 4.1 and the Lipid Maps database. The sign of two groups of samples in specific markers for screening was through a software package in R software (BioMark software). The results show that the pathological markers were mainly phosphatidylcholine (PC) and triglycerides (TG); the 2-acyl PC in the MC group was less more obviously than that in the NC group; high carbon number and high degree of unsaturation of the TG was reduced under the condition of type 2 diabetes. In the state of type 2 diabetes, metabolic changes occurred in rat plasma phospholipids obviously, which had a close relationship with the occurrence and development of T2DM.

Objective To evaluate the safety and efficacy of hepatectomy in combination with portal azygous disconnection for primary hepatocellular carcinoma (HCC) complicated with severe portal hypertension (PHT). Methods Clinical data of 30 cases of HCC complicated with PHT treated in our hospital from April 2005 to April 2008 were retrospectively analyzed. All 30 cases were randomly divided into the single operation group (group Ⅰ ) and combined group (group Ⅱ ). Results After operation, there were no significant statistical differences in rates of complications such as hepatic encephalopathy, ascites, stress ulcer, etc. and recovery of liver function between the 2 groups. The WBC and PLT counts in the blood samples of group Ⅱ were higher than those in group Ⅰ after operation. The postoperative 1- and 2-year hemorrhagic rates were lower in group Ⅱ than in group Ⅰ .Conclusion Hepatectomy in combination with portal azygous disconnection is safe and feasible for treatment of HCC complicated with PHT.

Objective To study the effectiveness of microwave ablation in treating HCC.Methods A total of 98 nodules in 56 cases of HCC were treated via appropriate puncture approach ac-cording to the volume, amount and site of tumor nodules. Results Only 1 patient failed to finish treatment since he could not suffer the pain. The other 55 patients finished without a hitch. Clinical and imaging findings were analyzed for change of physiology. Conclusion The microwave ablation is effective for the treatment of HCC. Such therapy can be important supplement of direct surgical man-agement. Its effect mainly depends on accurate puncture approach and enough diametric range. Mean-while, reasonable puncturing method should be selected.

Objective To prospectively compare the clinical effect of 131I therapy for Graves disease (GD) using the 131I-iodide dose determined by radioactive iodine uptake formula and by individualized experience method respectively.Methods (1) A total of 527 GD patients referred for 131I therapy were enrolled and divided into two groups using interval sampling method.Group 1 consisted of 241 patients with their 131I activity calculated by iodine uptake formula.Group 2 consisted of 286 patients with their 131I activity calculated by individualized method based on clinical experience.(2) The patients who were not cured for the first time were retreated after 3 months in the same way until remission.(3) All patients were followed for more than 1 year after GD was cured.The clinical outcome was compared between the 2 groups.x2 test and two-sample t test were used for data analysis.Results There were no significant differences in age,gender,disease course,ATD pretreatment,the time of ATD discontinuation,level of thyroid hormone and autoantibody before 131I therapy,131I uptake rate,size of thyroid and duration of follow-up between the two groups (t=0.156-1.430,x2 =0.159,all P>0.05).Group 1 had less 131I dose than group 2 ((247.9± 107.3) MBq vs (329.3±177.6) MBq,t=6.102,P<0.05),fewer patients whose disease was controlled at early stage (x2 =25.279,P<0.05) and lower remission rate for the first time of treatment (x2 =13.074,P< 0.05),but higher repeated treatment rate (t =2.735,P<0.05) and ratio of hypothyroidism to normalized patients at the first treatment (x2=10.190,P<0.05).The number of patients with permanent hypothyroidism between the two groups had no statistically significant difference (x2=1.138,P>0.05).Conclusions The first treatment dose of 131I by individualized experience method is slightly higher than that by radioactive iodine uptake formula.Individualized treatment method for GD based on experience might help to control the GD earlier and improve the one-off remission rate without increasing the rate of hypothyroidism.
