It has been 50 years since the discovery of thyrotropin receptor autoantibody (TRAb). Advances in the knowledge of thyrotropin receptor ( TSHR) structure and function, combined with the elucidation of TSHR signaling and TSHR-autoantibody interaction have greatly facilitated our understanding of TRAb and their clinical applications. Measurement of TRAb activity plays an important role in the diagnosis of Graves' disease ( GD) and Graves' opthalmopathy. It has also been well recognized that TRAb is an effective predictor of GD relapse or remission after antithyroid drug and radioactive iodine treatment. TRAb test is of particular help in pregnant women and lactating mothers with recent iodine load, where radioactive iodine or technetium tests are contraindicated. In addition, it is useful in the diagnosis and differential diagnosis of fetal and neonatal hyperthyroidism as well as some rare forms of thyrotoxicosis in clinical practice. Accumulating evidence also indicates the possible correlation between thyroid cancer occurring in GD patients with positive TRAb and adverse outcomes. However, further innovation and standardization of TRAb tests are required to help pave the way for clinical applications.

Objective To study the prevalence of thyroid disease in pregnant women living in both excess and sufficient water iodine area of in Jiangsu Province,and to establish an epidemiological database of thyroid disorders among pregnant women in different water iodine area in Jiangsu Province in order to guide our clinical practise.Methods Fengxian and Suining of Xuzhou were selected as excess and sufficient water iodine region.All the 439 pregnant women within the first trimester were enrolled in our study.The name,age,and previous history were recorded on questionnaire.The samples of fasting blood were obtained.Serum parameters such as free triiodothyronine ( FT3 ),free thyroxine ( FT4 ),total thyroxine ( TT4 ),thyrotropic stimulating hormone ( TSH ),and thyroid peroxidase (TPOAb) were measured by electrochemiluminescence assay.The data of the eligible 396 subjects were stored and analyzed by Epidata after excluding subjects with previous thyroid dysfuncion,renal disease,heart disease,and pregnancy-induced hypertension syndrome.Results Among the 396 subjects,197 women ( 49.7％ ) had thyroid disorders. The prevalence of hyperthyroidism, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism,hypothyroxinaemia,and thyroid autoimmunity were 0.5％,6.3％,3.3％,29.3％,9.3％,and 1.0％,respectively.The prevalence of subclinical hypothyroidism was significantly higher in excess water iodine region (32.4％) than that in sufficient water iodine area ( 19.6％ ),while the prevalence of other types of thyroid diseases such as subclinical hyperthyroidism,hyperthyroidism,hypothyroidism,hypothyroxinaemia,and TPOAbpositive cases in either excess or sufficient water iodine regions was not different.Conclusions Subclinical hyperthyridism,hypothyroxinaemia,and subclinical hypothyroidism are the main thyroid disorders in pregnant women in both excess and sufficient water iodine area.The prevalence of subclinical hypothyroidism increases obviously in excess water iodine region,indicating the relationship between thyroid disease and high iodine intake.

Objective To investigate the effect of HbA1c meeting the standard or not on microalbuminuria,blood lipids and liver enzymes in patients with type 2 diabetes.Methods A retrospective analysis was performed on 457 subjects who had type 2 diabetes.They were divided into substandard group and standard group according to HbA1c result.The general information and relevant laboratory indicators of patients were.collected and compared between two groups.Results The microalbuminuria,serum triglyceride and liver enzymes (glutamyl transpeptidase,alkaline phosphatase,aspertate aminotransferase) were significantly different between two groups [ (189.8 ± 235.3) mg/dl vs (38.9 ± 85.5) mg/dl,(2.64 ± 2.99) mmol/L vs (2.02 ± 1.50)mmol/L,(41.7 ±52.9)U/L vs (29.7 ±24.9)U/L,(83.6 ±28.6) U/L vs (74.3 ±25.8)U/L,(26.7 ±19.1)U/L vs (22.0 ±10.5) U/L,P ＜0.05].HbA1c level was positively correlated with microalbuminuria,glutamyl transpeptidase and alkaline phosphatase (r =0.209,0.115,0.11,P ＜0.01).The microalbuminuria was an independent risk factor of affecting HbA1c to reach the standard (OR = 1.009,P ＜0.05).Conclusions HbA1c meeting the standard or not can influence many factors except blood glucose.

Objective:The purpose of this study is to investigate the expression of tumor stem cell marker aldehyde dehydrogE-nase 1 (ALDH1) in breast cancer and its clinical significance. Methods:The expression of ALDH1 protein was examined by immunohistochemical staining in 92 breast cancer tissues. The correlation analysis and diseasE-free survival analysis of patients was evaluated based on the clinical follow-up data. Results:Expression of ALDH1 protein had a significant correlation with progesterone receptor (PR) and cerb-B2 (P<0.05), but had no significant correlation with age, tumor size, clinical staging, and lymph node metastasis (P>0.05). The 2-year diseasE-free survival rate of AlDH1-positive patients was lower than that of ALDH1-negative patients (P<0.05). ALDH1-positive patients, who received CEF regimen chemotherapy and hormone therapy, had lower 2-year diseasE-free survival rate than that of ALDH1-negative patients (P<0.05). Conclusion:The decreased diseasE-free survival rate of ALDH1-positive patients is related with drug resistance. ALDH1 could be used as an independent factor for predicting the prognosis of breast cancer.

The expression of resistin protein in normal human abdominal, thigh, pregnant women abdominal, non-pregnant women abdominal subcutaneous adipose tissue and placenta and the relationship between obesity, type 2 diabetes mellitus (T2DM), pregnant physiological insulin resistance (IR) and gestational diabetes mellitus (GDM) was investigated. The expression of resistin protein in normal human abdominal, thigh, pregnant women abdominal, non-pregnant women abdominal subcutaneous adipose tissue and placenta was detected by using Western blotting method. Fasting serum glucose concentration was measured by glucose oxidase assay. Serum cholesterol (CHOL), serum triglycerides (TG), serum HDL cholesterol (HDL-C) and serum LDL cholesterol (LDL-C) were determined by full automatic biochemical instrument. Fasting insulin was measured by enzyme immunoassay to calculate insulin resistance index (IRI). Height, weight, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured to calculate body mass index (BMI) and body fat percentage (BF %). Resistin protein expression in pregnant women placental tissue (67 905 +/- 8441) (arbitrary A values) was much higher than that in subcutaneous adipose tissue in pregnant women abdomen (40 718 +/- 3818, P < 0.01), non-pregnant women abdomen (38 288 +/- 2084, P < 0.01), normal human abdomen (39 421 +/- 6087, P < 0.01) and thigh (14 942 +/- 6706, P < 0.001) respectively. The resistin expression in abdominal subcutaneous adipose tissue showed no significant difference among pregnant, non-pregnant women and normal human, but much higher than that in thigh subcutaneous adipose tissue (P < 0.001). Pearson analysis revealed that resistin protein was correlated with BMI (r = 0.42), fasting insulin concentration (r = 0.38), IRI (r = 0.34), BF % (r = 0.43) and fasting glucose (r = 0.39), but not with blood pressure, CHOL, TG, HDL-C and LDL-C. It was suggested that resistin protein expression in human abdominal subcutaneous adipose tissue was much higher than that in human thigh subcutaneous adipose tissue. Resistin was closely related with central obesity, leading to IR, subsequently obesity and T2DM. Resistin protein expression in placental tissue was much higher than that in subcutaneous adipose tissue in normal human abdomen, pregnant abdomen, non-pregnant women abdomen and thigh. It was indicated that resistin protein could be secreted from human placental tissue. Resistin might be one of the factors that lead to pregnant physiological IR and GDM.

Objective:To explore the effect of core muscle strength training intervention on postoperative rehabilitation of patients after total knee arthroplasty, and to provide reference for the rehabilitation of patients after total knee arthroplasty.Methods:A total of 109 patients with total knee arthroplasty who were admitted to Medical Health Group of First People′s Hospital of Xiangshan County from May 2020 to July 2021 were selected as the research objects, and were divided into an intervention group of 54 cases and a control group of 55 cases according to the random number table method. The control group received conventional rehabilitation methods after surgery, and the intervention group received core muscle strength training on the basis of conventional rehabilitation. The intervention time was 6 weeks. The knee joint function, balance function and activities of daily living were evaluated by Hospital for Special Surgery Knee Score, Berg Balance Scale, modified Barthel Index before and after intervention and the results were compared between the two groups.Results:In the end, there were 50 cases in the intervention group and 52 cases in the control group. There was no significant difference in the score of the knee joint function, balance function and activities of daily living before intervention between the two groups( P>0.05). The scores of the knee joint function, balance function and activities of daily living were (74.78 ± 3.12), (46.50 ± 3.82), (92.80 ± 5.17) points in the intervention group, and (72.15 ± 3.31),(44.44 ±3.66),(89.42 ± 4.50) points in the control group, the differences were statistically significant ( t=4.12, 2.78, 3.52, all P<0.01). The knee joint function recovery grade in the intervention group was higher than that in the control group, and the difference was statistically significant ( Z=3.43, P<0.01); the degree of dependence on self-care ability in daily life in the intervention group was lower than that in the control group, and the difference was statistically significant ( Z=3.98, P<0.01). Conclusions:Core muscle strength training can effectively improve postoperative knee function, balance function and activities of daily living in patients with total knee arthroplasty. This program is practical in clinical work and has clinical application value.
