Objective To evaluate the effect of situational health education in glycemic control in type 2 diabetes patients.Methods A total of 98 patients with type 2 diabetes was randomly assigned to the control(n=49)and the study group(n=49).The control group received conventional diabetes education,while the study group received situational health education.Fasting blood glucose(FBG),2-hour plasma glucose (2 hPG),HbAlc and the self-care behaviors were observed at baseline and 1-year after the intervention.Paired t test was used for data analysis.Results FPG,2hPG,HbA1c and self-care behavior scores were not significantly different between the two group at baseline.After 1-year intervention,FPG,2hPG and HbA1c of the two groups were significantly decreased,and FPG,2hPG and HbA1c of the study group were significantly lower than those of the control group(t values were 2.71,3.35 and 2.90,respectively; all P＜ 0.05).In comparison with the control group,self-care scores of the study group were increased(t values were 7.36,6.51,5.24,5.07,6.57 and 6.77,respectively; all P＜0.05).Conclusion Situational health education could improve self-management and glycemic control of type 2 diabetic patients.

Objective To investigate the surrounding and central dosimetric distribution difference of the same activity, same number of 125I seeds. Methods 3D treatment planning system (3D-TPS) was used to separately sketch out 7 cubes with side length of 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm and 5 cm;simulations of different tumor sizes were established, into which 125I seeds with activity of 0.5 mCi were respectively loaded. All seeds were distributed at the periphery of the tumor (peripheral group) with the prescribed dose of 145 Gy. The dose volume histogram (DVH) was printed and the 90% of target volume absorbed dose (D90), 90% of prescription dose coverage target volume percentage (V90), the maximum dose and mean dose were determined. Then the seeds in every cube were distributed into the center (central group) and the above parameters were calculated by using the same method. Results The mean D90 of the peripheral and central group was (147.29 ±0.58) Gy and (106.08 ±9.40) Gy respectively, the difference between the two groups was statistically significant (t=-4.292, P=0.005). The mean V90 of the peripheral and central group was (95.46±0.44)% and (79.07±4.19)% respectively, the difference between the two groups was statistically significant (t=-3.831, P=0.009). The mean maximum dose of the peripheral and central group was (1 224.65 ±12.7) Gy and (1 532.48 ±48.54) Gy respectively, the difference between the two groups was statistically significant (t=6.823, P=0.000). The mean value of average dose of the peripheral and central group was (192.14 ±2.89) Gy and (179.81 ±5.40) Gy respectively, the difference between the two groups was statistically significant (t=-2.847, P=0.029). Conclusion The dose distribution is directly influenced by the distribution pattern of the 125I seeds. When the number and activity of the 125I seeds are the same, the peripheral seeds implantation has a better dose distribution.

Objective To study the effective dose and precaution time of the irradiation of the close contact from the radiators who underwent implantation of radioactive 125Ⅰ seeds so as to guide scientifically people how to avoid radiation damage.Methods Twenty patients with different types of cancer underwent implantation of radioactive 125Ⅰ seeds with the median value of implantation depth of 2.16 cm.Within 24hs after the operations the dose rates 30 cm and 100 cm from the skin were measured with pocket-size radiometer so as to imitate the situations of the close contacts.The effective doses and precaution times of different persons were calculated according to relevant formula.Results The dose rate a person received at the same time points (1,54,78,and 109 d,respectively) decreased along with the increase of the distance from the skin (t =5.962,5.961,5.961,5.962,P ＜ 0.05).and the dose rate a person received at the same distance from the skin decreased along with the extension of time (30 cm:t =6.236,6.236,6.235,P＜0.05;100 cm:t=7.310,7.315,7.314,P＜0.05).At different time points,the dose rates at 30 cm distance point were all significant higher than those at the 100 cm point (P ＜0.05).The adult living together,minors and pregnant women sharing the room,colleagues,adults who slept together with the patients began to reach the 50％ dose constraint values 0,54,78 and 109 days after the operation.Conclusions After their precaution time,it's safe to contact with the patients for the groups;otherwise,it's necessary to take some protect works within the precaution time.

OBJECTIVE：To evaluate the pharmacoec onomics of Enalapril folic acid tablet and Enalapril tablet for stroke prevention in patients with hypertension. METHODS ：Markov model was constructed by using Excel 2016 software. Patients with essential hypertension were selected as the research object with 1 year cycle and 20 years horizon. From the perspective of health system，the pharmacoeconomics of Enalapril folic acid tablets versus Enalapril tablets for stroke prevention in patients with hypertension was compared by cost-effectiveness analysis ，and the stability of the research results was verified by sensitivity analysis. RESULTS ：Compared with Enalapril tablet ，the incremental cost-effectiveness ratio of Enalapril folic acid tablet was 221 323 yuan/QALY，which was higher than three times of China ’s per capita GDP in 2020（217 341.04 yuan）. The results of single factor sensitivity analysis and probabilistic sensitivity analysis were consistent with that of basic analysis. CONCLUSIONS ： Compared with Enalapril tablet ，Enalapril folic acid tablet doesn ’t have a better economy for patients with hypertension.
