Objective: To study the effect of emotion on blood pressure of patients with primary hypertension Method: 100 patients with primary hypertension completed SAS (self-rate anxiety scale) and Type A Behavior Questionnaire 62 of them had typical type A behavior, they were divided into two groups by results of SAS, 34 were SAS negative, 28 were positive The 28 patients were randomly divided into two groups, 14 received Lorsartan 50 mg daily for 30 days, the other 14 received both Paroxetine 20 mg daily and Lorsartan 50 mg daily for 30 days The 34 SAS negative patients also received Lorsartan 50 mg daily for 30 days Result: The positive rate of SAS was significant different between type A patients (28/62, 45 2%) and non-type A patients (4/38, 10 5%) In treatment of hypertension, the effective rate of Lorsartan in patients neither anxious nor type A predominant was 79 4%, that in the 14 patients with both anxiety and type A behavior was only 57 1% While in those using Lorsartan and Paroxetine, the effective rate was 78 5%, similar to that in patients neither anxious nor type A predominant Conclusion: Anxiety is much more common in hypertension patients predominant in type A behavior Treatment of anxiety is helpful to treatment of hypertension in patients both anxious and type A behavior predominant

Objective To introduce the methods and key points for the external fixation combinel with limited percutaneous internal fixation plus colostomy in the treatment of open pelvic fracture concomitant with perineal laceration.Methods Nine patients with open pelvic fractures concomitant with perineallaceration were treated by external fixator combined with limited percutaneous internal fixer plus colostomy. Data including injury details, management and outcomes were collected for comparison.Results All the patients survived and attained bony union except for two patients with local infection that was healed several days after repeated wound debridement and use of wide spectrum antibiotics. All the patients had good extremity function at the latest follow-up. Conclusion External fixation combined with limited percutaneous internal fixation plus colostomy is a reliable, safe and less invasive procedure for the treatment of open pelvic fractures concomitant with perineal open wound.

Objective:To study the radiation dose rate and effective dose in ambient environment due to 125I seed implantation in the treatment of the patients suffering abdominal and pelvic tumors, so as to provide reference for occupational protection of different groups. Methods:Within 24 hours after operation, the radiation dose rate to 42 patients with abdominal and pelvic tumor with 125I seed implantation was monitored by using pocket dosimeter. The relationships between the total activity in the implanted particles and the measured dose rate, as well as between the implanted depth and the dose rate under the standard activity, were obtained by curve fitting. According to the formula, the relationship between the dose rate and the warning time was calculated. Results:The dose rates at 30 cm, 50 cm and 100 cm of vertical particle implantation site were (6.92±2.87), (4.10±1.62) and (1.30±0.48) μSv/h, respectively ( χ2=73.71, P<0.05). The dose rates on the left and right sides were (0.378±0.156) and (0.384±0.153) μSv/h at 30 cm, (0.170±0.089) and (0.17±0.086) μSv/h at 50 cm, (0.039 ±0.014) and (0.043±0.017) μSv/h at 100 cm, respectively ( χ2=76.19, 76.33, P<0.05). There was a linear relationship between the dose rate at the vertical particle implantation site and the total activity in the implanted particles, and between the dose rate and the implantation depth under the standard activity. The relationship between the warning time and the dose rate to adults in the same bed, co-workers, minors in the same bed and pregnant women were as follows: t ( d)=-106.616+ 83.779ln D( t), t ( d)=26.556+ 85.933ln D ( t), t( d)=3.088+ 85.017ln D( t). Conclusions:After 125I seed implantation, the radiation dose in the ambient environment is low, ensuring the radiation safety; and the measured dose rate decreases with the decrease in the total activity in the implanted particle and the increase in the implantation depth; at the same time, the warning time for different groups is calculated according to the measured dose rate or the total activity in the implanted particle and the depth of the implanted particle, so as to carry out individualized protection.
