RESUMO
Objective To understand the situation of iodine of Taishan nuclear power station employees,and assess the relationships between iodine nutrition and thyroid nodule of Taishan nuclear power station in Taishan,Guangdong.Methods Totally 300 people were selected from of Taishan nuclear power station through stratifiedrandom sampling method,random urine samples were collected and urinary iodine level was tested in 2014.According to 20 to 29 years old,30 to 39 years old,40 to 59 years old,3 age groups were sampled,and each age group was 100 people.Drinking water and edible salt samples of the of nuclear power station were collected and iodine level was tested.Daily dietary intake of the staff was investigated,and daily iodine intake was calculated.Result of thyroid B ultrasonic of the employees (1 091) were studied,and detection rate of thyroid nodule was calculated.Results Totally 308 urine samples were tested,and the median urinary iodine was 193 μg/L.The difference of urinary iodine between 20-year-old group (201 μg/L) and 30-year-old group (165 μg/L) was statistically significant (P ＜ 0.05).A total of 9 iodized salt samples were collected,with an average iodine value of (24.4 ± 0.5)mg/kg.A total of 9 water samples were collected,the median of water iodine was 20.5 μg/L in 3 centralized water supply samples.The daily iodine intake per capita of the staff was 274.0 μg/d,the highest contribution among all the varieties of food was iodized salt,the second was seafood,which were 45.26 percent and 41.86 percent,respectively.A total of 99 thyroid nodules and suspicious nodules were detected in 1 091,and the prevalence was 9.07 percent (99/1 091).The prevalence of people aged 40-59 [15.6％ (22/141)] was significantly higher than those of people aged 20 to 29 [8.1％ (51/633)] and aged 30 to 39 [8.2％ (26/317)],and the differences were statistically significant (P ＜ 0.05).Conclusions The iodine nutrition of Taishan nuclear power station employees is appropriate as a whole.The detection rate of thyroid nodules is higher in people aged 40 to 59.
RESUMO
Objective To discuss clinical efficacy of taking drospirenone and ethinylestradiol tablets in preventing intrauterine adhesion after missed abortion curettage with b-ultrasonic observation.Methods216 cases of study objects provided with missed abortion curettage with b-ultrasonic observation were divided into control group with 108 cases and research group with 108 cases.Patients in control group were provided with conventional treatment after surgery, while those in research group were provided with conventional treatment and drospirenone and ethinylestradiol tablets.Two groups were compared for condition after surgery such as intrauterine adhesion in 1month after treatment, secondary pregnancy, infertility and abortion in 1 year after treatment.ResultsTime of vaginal bleeding, pelvic effusion and time of return of menses in research group were significantly lower than those in control group, with difference having statistical significance (t=6.114,t=9.481,t=9.201,P0.05).In the case of infertility rate and rate of abortion in 1 year after treatment, control group was higher than research group with difference having statistical significance (χ2=4.317,χ2=5.225,P<0.05).ConclusionTaking drospirenone and ethinylestradiol tablets after missed abortion curettage with b-ultrasonic observation can effectively prevent intrauterine adhesion, which can also reduce complications such as abortion and infertility, therefore, it shall be applied in accordance with specific condition of patients.
RESUMO
@#Objective To investigate the feasibility and curative effect of botulinum toxin type A(BTX-A)point injection under the guidance of type-B ultrasonic on upper limb spasticity after stroke.Methods 18 cases were divided into two groups:9 cases for treatment group were treated with point injection BTX-A in 5 points with the guidance of type-B ultrasonic diagnosis,other 9 cases for control were only injected experientially.They were evaluated with the modified Ashworth scale(MAS)and the time taking effect were recorded.Results Compared with the control,the scores of MAS in the treatment group improved,and they came into effect more quickly(P<0.05).Conclusion The point injection of BTX-A under the guidance of type-B ultrasonic was practicable for and effective on upper limb spasticity after stroke.
RESUMO
Objectives To evaluate the clinical efficacy of treatment uterine leiomyoma using radiofrequency ablation. Methods From September 2004 to March 2005, 30 patients of uterine leiomyoma were treated using radiofrequency ablation under B ultrasonic scouting; the diameter of uterine leiomyoma was 1.5～4.8cm. Results The 30 patients were callback after the operation 3～6 months; the curative effect rate was 100%, including cure rate 50%, obvious effect rate 33.3%, and efficient effect rate 16.7%. Conclusion The radiofrequency ablation is a simple, safe, effective and economic technique with tiny hurt and remains the functions of uterine on the therapy of uterine leiomyoma.
RESUMO
This paper introduces the development of B-ultrasonic wave video image acquisition and management system based on Windows of the PC.With the application of VB6.0,the acquisition and dynamic display of B-ultrasonic wave video image are realized.ACCESS taken as the database and its ADO application set up,the system has the functions of query,statistics and report of B-ultrasonic wave video image.
RESUMO
Objective To introduce a kind of UPS for portable type-B ultrasonic in vehicular-charging at the situation of flowing in battle field. Methods Long time power supply for type-B ultrasonic and other related medical devices was realized through AC/DC alteration switch. Conclusion It functioned well in field test. Conclusion Being light and convenient with AC/DC, it is worth popularizing.
