The drug-loading capacities of sustained particles before and after coating were 35.23%,32.72%,respectively;the yield was 96.82%. The carbinoxamine ma-leate in prepared sustained-release suspension accounted for 98.76% of the labeled amount;release degree in 10 h reached about 80%,f2 was 65.73. CONCLUSIONS:Carbinoxamine maleate sustained-release suspension is prepared successfully,and its release is similar to the original preparation.

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.

Objective To identify the changes of body composition with acromegaly before and after pituitary adeno-ma surgery,and to evaluate the relationship between these changes and serum growth hormone(GH),insulin-like growth factor-1(IGF-1).Methods Serum GH with OGTY,IGF-1 levels,BMI,fat percentage,FFM and total body water(TBW) in patients were measured in active and relieved period of the disease.Results The BMI and FFM with active acromegalic males were significantly higher,but fat percentage was significantly lower than that of healthy males.After the disease was relieved by surgery,serum GH and IGF-1 concentrations of patients were sig-nificantly reduced to normal level,but their BMI was still significantly higher,the fat percentage increased and the FFM decreased was correlated with serum nadin GH and IGF-1 levels.The BMI and FFM with active acromegalic females were significantly higher than healthy females,but the fat percentage had not significant change after sur-gery,and FFM decrease was correlated with reduced serum GH level.The fat percentage did not change signifi-cantly.Conclusion There was significant change of body composition with acromagely before and after treatment,and a relationship between these changes and serum GH and IGF-1 levels was identified.

Objective To investigate the effect of folic acid intervention on plasma homocysteine (Hcy) metabolic changes and pulse wave velocity(PWV)in patients with type H hypertension. Methods Patients(hos-pitalized from March 2014 to December in our hospital)with H type hypertension were randomly divided into treat-ment group and control group randomly ,and were given routine antihypertensive drug therapy. Treatment group was given oral folic acid 0.8 mg,1 times a day,the control group was given placebo,1 times a day. All patient were treated for 12 months. Changes of plasma Hcy and PWV levels were observed. Results 432 patients(Han nationality)with type H hypertension were enrolled in this study with the age of 61.7 ± 13.6 years old and the ratio of men and women is 1.3:1. The most common diseases were coronary heart disease and type 2 diabetes mellitus. 2 groups were treated for a period of 12 months,with follow-up time from 6 to 10 months(average duration in 8 months). After treatment,the difference between plasma Hcy(Z=-7.63,P=0.000)and PWV(Z=-3.16,P=0.002)levels of the two groups were statistically significant. Conclusion Folic acid intervention can significantly reduce the level of plasma Hcy in patients with type H hypertension ,slow down the progression of atherosclerosis and reduce the risk factors of cardiovascular disease.

OBJECTIVESTo summarize the clinical experience of preoperative intraarterial chemotherapy (PRAC) and evaluate the long-term results of multimodality against colorectal cancer.

METHODSSeldinger procedure was used to intubate the tube to the artery branch which supplied blood to the tumor. The tumor was imaged to make sure the diagnosis and irrigate the chemotherapeutic drugs. Ten days after PRAC, the patients received radical operation and 6 chemotherapeutic courses with FCF regimen. Concurrent patients receiving surgical treatment yet no PRAC therapy were chosen as controls.

RESULTSOne-year survival rate was 93.05% in the PRAC group and 80.78% in the controls (P = 0.023). COX multivariate analysis was used to analyse the prognostic factors. Dukes'staging and the PRAC prescription or not were found to be independent prognostic factors of colorectal cancer patients. Patients in the PRAC group survived longer than those in the control group.

CONCLUSIONPRAC can improve the survival of colorectal cancer patients.
