Objective To study the effects of quantitative 24-hour urinary protein on the thyroid hormone levels in patients with severe preeclamp-sia,and clarify the impact of severe urinary protein on hypothyroid in severe preeclampsia patients. Methods A total of 166 patients with severe pre-eclampsia were recruited for the study and divided into mild proteinuria group(2.0-4.9 g/d),midrange group(5-10 g/d)and severe group(>10 g/d)according to the quantitative 24-hour urinary protein. 268 healthy female individuals with normal blood pressure and uric routine in the same stage of pregnancy and of the same age were selected into control group. Serum thyrotropin(TSH),free triiodothyronine(FT3)and free thyroxine (FT4)levels were determined by solid-phase chemiluminescent enzyme immunoassay method(CMIA). The thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)concentration were detected by electrochemiluminescent assay(ECLIA). Results TSH levels were signifi-cantly higher in patients comparing to the control group(P<0.01). In addition,severe group showed higher TSH levels than mild group(P<0.01). FT4 and FT3 levels were obviously decreased with the progression of the disease(P<0.01 and P<0.05). The positive rate of TPOAb in mild group was significantly higher than that in moderate group(OR=9.8,P<0.05). There was no significant difference of the TGAb positive rate among three patient groups(P>0.05). The incidence of subclinical hypothyroidism and clinical hypothyroidism in severe group was significantly higher than that in mild group and in control group(OR=2.5,P<0.05 and OR=9.0,P<0.05;OR=8.0,P<0.01 and OR=43.4,P<0.01). Conclusion Our re-sults indicated that 24-hour urine protein in severe preeclampsia patients has extensive effects on thyroid hormones levels. With the increasing of quantitative 24-hour urinary protein,the level of TSH increased and the FT4 decreased. Thyroid autoantibody positiveness has extensive effects on 24- hour urine protein. Incidence of hypothyroid increased with the increase of quantitative 24-hour urinary protein. 24-hour urinary protein quantitative was a risk factor for hypothyroidism in severe preeclampsia patients. More attention should be paid to the monitoring of 24-hour urinary protein in se-vere preeclampsia patients.

Objective To study effects of different degree of hypothyroidism in severe preeclampsia (S-PE) pregnant women on renal function and the correlation between them.Methods 46 S-PE patients with subclinical hypothyroidism (SCH) registered for treatment in the Shengjing Hospital of China Medical University from May 2011 to March 2013 were selected into SCH group,and 23 S-PE with overt hypothyroidism (OH) were selected into OH group,and 109 S-PE with normal thyroid stimulating hormone (TSH) levels were selected into simple group.Thyroid hormone and kidney function tests were analyzed in pregnant women with S-PE.We made an analysis of the relative risk of the detection rate of abnormal renal function and also the relationship between the levels of thyroid hormone and serum uric acid,serum urea and creatinine in patients with S-PE.Results (1) In SCH group serum TSH was (6.1±3.2) mU/L,free triiodothyronine (FT3) was (4.0±0.6) pmol/L,free thyroxine (FT4) was (11.8± 1.5) pmol/L; in OH group serum TSH was (5.2± 1.3) mU/L,FT3 was (3.7±0.6) pmol/L,FT4 was (9.3±0.5) pmol/L; in simple S-PE group serum TSH was (1.9±0.8) mU/L,FT3 was (4.0±0.8) pmol/L and FT4 was (11.9±1.9) pmol/L.TSH in SCH group was significantly higher than that in simple S-PE group (P>0.01),the difference of in SCH and OH group were not statistically significant (P>0.05).The difference of FT3 in three groups were not statistically significant (P<0.05) ;FT4 in OH group was significantly lower than thoes in SCH and simple groups (P<0.05).(2)Serum uric acid,creatinine and urea levels in OH group was (436± 114),(75± 15) μmol/L and (6±3)mmol/L,in simple S-PE group they were (378± 114),(65 ±22) μmol/L and (5±3) mmol/L.In comparison,the differences was statistically significant(P<0.05).The differences were not statistically significant in SCH and OH groups (P>0.05).(3)The abnormal detection rate of uric acid was significantly higher in SCH than that in OH group [46% (21/46) versus 22% (5/23),OR=3.0,P<0.05].The comparison of remaining index has no statistical significance(P>0.05).(4)In SCH group there was a significant inverse correlation of serum FT3 with serum urea levels,serum creatinine and serum uric acid (r=-0.32,-0.58,-0.35,P<0.05).There was not a correlation of serum TSH,FT4 with indicators of renal function (P>0.05).In OH group there was a negative correlation between FT3 and serum creatinine concentrations (r=-0.40,P<0.05).In OH group there was not a correlation of FT3 with serum uric acid and urea (P>0.05).There was a positive correlation between TSH and serum creatinine in simple S-PE group (r=0.20,P=0.04).There was not a correlation between TSH and serum urea(r=0.04,P=0.65),and serum uric acid (r=0.12,P=0.20).Conclusions There was effect of different hypothyrosis state in pre-eclampsia patients on renal function.Serum uric acid,urea and creatinine concentrations in S-PE pregnant women with OH were significantly higher than those in simple S-PE group with normal TSH.There was a negative correlation between FT3 and serum creatinine in S-PE.Hence the thyroid function should be regularly monitored in S-PE patients to find damage of renal function and management hypothyrosis.

Objective To investigate the effects of multimedia information technologies on precision radiotherapy of head and neck malignant tumors (HNT). Methods A total of 96 patients with HNT recruited from 2016 to 2019 were randomly assignedto group A and group B with the same planning methodand therapists/technicians. Conventional and multimedia information technologies were respectively used in group A and group B for medical science popularization, individualized education, and doctor-patient communication before radiotherapy planning and positioning. Medical compliance, radiotherapy responses, setup errors, and machine occupancy time were investigated. Results Medical compliance was significantly higher (P < 0.05) in group A (96.5%) than in group B (73.8%). Skin acute radiation reaction was significantly lower (P < 0.05) in group A than in group B. Three-dimensional absolute setup errors were 0.69 ± 0.29 mm, 0.97 ± 0.69 mm, and 0.79 ± 0.47 mm in group A, which were significantly lower than 1.39 ± 0.81 mm, 1.87 ± 1.19 mm, and 2.50 ± 0.99 mm in group B(P < 0.05). Traditional three-dimensional setup errors were 0.73 ± 0.39 mm, 0.51 ± 0.69 mm, and 0.74 ± 0.17 mm in group A, which were significantly lower than 1.32 ± 0.76 mm, 1.89 ± 1.21 mm, and 1.37 ± 0.57 mm in group B (P < 0.05). Planning time was 145.15 ± 28.45 sin group A, which was significantly lower than 240.38 ± 50.45 sin group B (P < 0.05). Positioning time was 115.15 ± 18.45 s in group A, which was significantly lower than 173.38 ± 24.45 sin group B (P < 0.05). Conclusion The application of multimedia information technologies inmedical science popularization, individualized education, and doctor-patient communication forpatients who received precision radiotherapy for HNT can significantly increase patient compliance, alleviate acute radiation reactions, reduce setup errors, and shorten the machine occupancy time of planning and positioning.
