ABSTRACT

Objective:To observe the ratio of helper T cells 17 (Th17)/regulatory T cells (Treg) in peripheral blood of patients with Hashimoto's thyroiditis (HT) and the expression changes of related cytokines in serum, and to explore their role in the occurrence and development of HT.Methods:Using the case-control study method, 35 HT patients examined in the General Hospital of Heilongjiang Beidahuang Group from February to November 2019 were selected as HT group, and 39 healthy people in the same period were selected as control group. Early morning fasting venous blood samples of the two groups were collected to test the levels of thyroid stimulating hormone (TSH), free thyroxine (FT 4), thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb). The expressions of serum interleukin (IL)-6, IL-17 and transforming growth factor β (TGF-β) were tested by enzyme-linked immunosorbent assay (ELISA); the number of Th17, Treg in peripheral blood were determined by flow cytometry. Results:The levels of TPOAb, TgAb and TSH in HT group [130.60 (43.37, 714.40), 368.10 (136.90, 1 103.00) U/ml, 9.05 (6.62, 15.23) μU/ml] were significantly higher than those in control group [2.66 (1.52, 4.69), 12.63 (11.43, 14.60) U/ml, 1.87 (1.36, 2.23) μU/ml, U = 6.87, 6.62, 4.85, P < 0.001], and the FT 4 level [0.76 (0.63, 1.04) ng/dl] was lower than that in control group [1.14 (1.02, 1.26) ng/dl, U = 7.39, P < 0.001]. The expressions of IL-6, IL-17 and TGF-β in HT group were higher than those in control group ( t = 2.41, 9.04, 2.44, P < 0.05). The number of Th17 and the ratio of Th17/Treg in HT group were higher than those in control group ( t = 4.20, 3.50, P < 0.05), and the number of Treg was lower than that in control group ( t = 4.45, P = 0.001). Conclusion:In HT patients, Th17 are increased, Treg decreased, Th17/Treg ratio increased, and the expressions of IL-6, IL-17 and TGF-β are increased.

ABSTRACT

Objective To evaluate the clinical diagnostic value of color Doppler ultrasound in diagnosis brucellosis with orchitis.Methods Hospital-based case-control study was used.We selected the patients with brucellosis orchitis who were hospitalized in Heilongjiang Land Reclamation Bureau General Hospital from 2014 to 2016 as a case group.At the same time,selected healthy people as the control group.Bilateral testicular size,parenchyma echo,flow signals in parenchyma,depth of bilateral testicular sheath membrane cavity effusion,testicular artery peak systolic velocity (PSV),end-diastolic velocity (EDV),pulsatility index,resistance index,peak systolic velocity/end-diastolic velocity,were measured and analyzed using color Doppler ultrasound.Results The case group included 62 patients;the health control group included 41 persons.The testicular volume of case group was compared to that of healthy control group,there was no statistical significant difference (cm3:15.81 ± 3.27 vs 15.82 ± 2.77,t =0.015,P > 0.05).By analyzing the correlation between the course of the disease and the testicular volume,a negative relationship was found (r =-0.594,P < 0.01).In the case group,the deep diameter of the testicular sheath was higher than that of the healthy control group,and the difference was statistically significant (cm:1.50 ± 0.53 vs 0.84 ± 0.21,t =10.777,P< 0.01).The PSV and EDV were higher than those in the control group (cn/s:(9.73 ± 3.25 vs 6.00 ± 1.38,2.89 ± 0.77 vs 2.46 ± 0.36,t =9.810,4.691,P < 0.01).The pulsation index and resistance index were higher than that in the control group (1.06 ± 0.12 vs 0.82 ± 0.08,0.69 ± 0.05 vs 0.58 ± 0.04,t =15.678,12.763,P < 0.01).Conclusions There are specific changes in Brucella patients with orchitis.The blood flow spectrum and testicular sheath membrane cavity effusion are specific changes.The color Doppler ultrasound can effectively evaluate Brucella orchitis patients with testicular injury,provide a reliable imaging basis for clinical treatment.

ABSTRACT

Objective To explore the ultrasonic imaging features of malignant thyroid nodules risk fac-tors by logistic regression.Methods Two hundreds and forty patients with thyroid nodules by ultrasonic examina-tion and surgical treatment for patients with definited pathological diagnosis were included in this study.The pre-operative sonographic features of the nodules were put into the logistic regression model to explore the risk factors of ultrasonic imaging features of malignant thyroid nodules.Results By logistic regression model analysis,hypoe-cho,taller than wide≥1 and micro calcification were found to be significantly statistical variables for thyroid car-cinoma.Micro calcification could predict thyroid cancer for lymph node metastases.Conclusoin During clinical diagnosis,hypoecho,taller than wide more than 1 and micro calcification could be used as indicators by ultrasound doctors to judge malignant thyroid nodules and lymph node metastases.Prospective larger similar research is still very necessary to explore the indicator for thyroid carcinoma in the future.
