RESUMEN
Objective:To investigate the serum thyroglobulin (Tg) levels of women in early pregnancy in Dali City, Yunnan Province, and provide a scientific basis for evaluation of individual iodine nutrition of early pregnant women in this area.Methods:Dali City, Yunnan Province was divided into 5 sampling areas according to east, west, south, north and middle. One township (town) was selected from each area, and at least 20 women in early pregnancy were selected from each township (town) as survey subjects. General condition and medical history of all subjects were collected, and random urine samples and fasting venous blood samples were collected for determination of urinary iodine and thyroid function indexes, and a portable ultrasound machine was used for thyroid ultrasonography. After excluding the patients with a history of thyroid disease and abnormal thyroid function, the level of Tg in the included early pregnant women was analyzed.Results:A total of 120 women in early pregnancy were investigated, aged from 19 to 40 years. Among them, 61 cases came from urban areas and 59 were from rural areas. The median urinary iodine was 156.54 μg/L, which was at the appropriate level of iodine nutrition. A total of 102 women with normal thyroid function in early pregnancy were included, and the Tg level was 11.56 (6.67, 15.27) ng/ml. Among them, 58 cases were in urban areas and 44 cases were in rural areas. There was no significant difference in serum Tg levels between rural and urban women in early pregnancy ( U = 1 362.50, P = 0.559). Conclusion:The serum Tg level of women in early pregnancy in Dali City can provide a reference for evaluation of individual iodine nutrition of relevant populations in this area.
RESUMEN
Objective:To investigate and analyze the prevalence of thyroid disease during pregnancy in Dali, Yunnan Province, and to provide scientific basis for prevention and treatment of benign thyroid disease during pregnancy in the region.Methods:From July to December 2014, Dali in Yunnan Province was divided into 5 sampling areas according to east, west, south, north and middle. One township (town) was selected from each area, and at least 20 women in early, middle and late pregnancy, respectively, were selected from each township (town). To conduct this investigation, medical history data was collected, thyroid ultrasound examination and serological indexes of thyroid function test were performed based on the normal reference value of specific thyroid function serological indexes during pregnancy in this region.Results:A total of 370 cases of pregnant women were investigated, including 120 cases in early pregnancy (61 cases in urban areas and 59 cases in rural areas), aged 19 - 40 years; 126 cases in middle pregnancy (60 cases in urban areas and 66 cases in rural areas), aged 19 - 45 years; and 124 cases in late pregnancy (57 cases in urban areas and 67 cases in rural areas), aged 19 - 44 years. The detection rate of thyroid disease in pregnant women was 27.57% (102/370). The detection rate of thyroid dysfunction was 7.57% (28/370), the positive detection rate of thyroid antibody was 11.62% (43/370), and the detection rate of thyroid nodule was 13.51% (50/370). The detection rates of thyroid diseases in early, middle and late pregnancy were 33.33% (40/120), 23.02% (29/126), 26.61% (33/124), respectively, and the difference was not statistically significant(χ 2 = 3.362, P > 0.05). Conclusions:In Daliy, Yunnan Province, there is a high detection rate of thyroid diseases during pregnancy, especially in early pregnancy. Therefore, it is necessary to carry out further large-scale investigation and study to provide a more reliable scientific basis for prevention and treatment of thyroid disease during pregnancy in this region.
RESUMEN
BACKGROUND:The effect of proximal femoral anti-rotation nail fixation in repair of intertrochanteric fracture is better than the other fixation materials. Unarmed inserting guided needle plays an important role for the quality of intertrochanteric fracture fixation. At present, there have been short of fast and accurate methods for inserting femoral canal guided needle from trochanter. OBJECTIVE:To investigate the operating skil s and application value of unarmed inserting guided needle in the process of proximal femoral anti-rotation nail Ⅱ fixation in repair of intertrochanteric fracture. METHODS:Standard operating procedures of guided needle inserting were established. The location of the guided needle was correct or was not judged through discriminating the feeling of inserting into the tip of femoral canal guided needle from trochanter. Slight resistance prompted that guided needle was in correct position. The guided needle closed to the medial femoral cortex and moved downward in the medul ary cavity. The guided needle was confirmed in the correct position by the perspective of C-arm in positive side position. This process was just one lateral perspective. Smoothly without resistance prompted that if the guided needle was out of the medul ary cavity, the direction of the inserting needle needed to be changed, without perspective. The resistance would be large if the needle tip piercing the medial femoral cortical bone, at this moment, the direction of the needle needed to be adjusted;or was blocked by malreduction of fracture or the free fracture block off the medul ary cavity;at this moment, fracture ends needed to be further restored. The surgery time, the time required to complete the guided needle inserting, the amount of bleeding, weight-bearing ambulation time and complications of 19 patients with intertrochanteric fracture treated by proximal femoral anti-rotation nail Ⅱ fixation were statistical y analyzed. RESULTS AND CONCLUSION:The average completed time for internal fixation was 45 minutes, the average desired time for guided needle inserting was 80 seconds, the average blood loss was 100 mL. There was no wound infection, or pressure sore formation. The shimoji time was an average of six weeks after treatment. Al patients were fol owed up for 4-9 months. Three patients needed crutches to walk before treatment, and after three months of treatment, they returned to the pre-exercise levels of injury. These results suggest that the procedure of unarmed inserting the guided needle provides guidance for the quick and correct completion of needle inserting, so as to enhance the internal fixation quality of proximal femoral anti-rotation nail Ⅱ in repair of intertrochanteric fracture, with a high reliability. It can significantly reduce the number of perspective, shorten surgery time, reduce the amount of bleeding and reduce complications.
