Background:
Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension.
Methods:
Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017.
Results:
The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years.
Conclusion
The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

Objective To explore the relationship between different smoking status and hypothyroidism in six iodine-suitable areas of China. Methods A total of 8187 residents were investigated by cluster sampling in six cities, and 7448 residents were included in the survey. The height, weight, waist circumference, and blood pressure were measured by filling out epidemiological questionnaire. Blood samples were collected to detect thyroid stimulating hormone ( TSH) , thyroid peroxidase antibody ( TPOAb) , and thyroglobulin antibody ( TgAb) . Results The mean TSH, TPOAb, and TgAb positive rates in passive smoking and active smoking groups were all lower than those in non-smoking group ( all P<0.01) . In the active smoking group, the TSH value decreased by 0.023 units for every unit increase in smoking index. The positive rates of TgAb and TPOAb in both passive smoking and active smoking groups were lower than those in non-smoking group (all P<0.01). Active and passive smoking reduced the prevalence of hypothyroidism (both P<0.01). Among women, the risks of clinical hypothyroidism and subclinical hypothyroidism were reduced in both active and passive smoking groups. Besides, the risk of subclinical hypothyroidism decreased significantly when the smoking index was more than 70. In male population, the risk of subclinical hypothyroidism in active and passive smoking group decreased. Besides, the risk of clinical hypothyroidism and subclinical hypothyroidism decreased significantly when the smoking index was more than 70. Conclusion Smoking in iodine-suitable areas may reduce TSH level and the positive rates of TPOAb and TgAb.

Chinese Journal of Diabetes 2017;25(6):573-576
The relationship between Sulfonylureas(SUs) and cardiovascular (CV) risks has attracted great attention.Previous studies have illustrated that some SUs increase CV risk in type 2 diabetes (T2DM) patients;while others do not.Clinical studies have found that the CV risks of different SUs may be different.Compared with other SUs;glimepiride and gliclazide may have lower CV risks.Here we reviewed evidence-based CV safety of SUs and the recent research progress.

In 2015, American College of Endocrinology ( ACE), American Association of Clinical Endocrinologists ( AACE ) , European Association for the Study of Diabetes ( EASD ) , Chinese Society of Endocrinology, American Diabetes Association ( ADA ) , American Association of Diabetes Educators ( AADE ) , Academy of Nutrition and Dietetics(AND), etc. published several guidelines and statements on diabetes and its complications. The selection of hypoglycemic drugs, diabetes self-management education and support, the characteristics of blood pressure and blood lipid, the efficacy and adverse reaction of hypoglycemic drugs were also suggested and recommended. These guidelines and statements will play key roles in the clinical diagnosis and treatment of diabetes mellitus, which is reviewed in this article.

[Summary] Thyroid nodules are the most common endocrine and metabolic diseases,and most of them are accidental nodules.How to distinguish the state between benign and malignant thyroid nodules is the clinical core problems in diagnosis and treatment.In addition to detailed history collecting and physical examination,highresolution ultrasound,serum thyrotrophin levels,and fine needle aspiration biopsy (FNAB) form the basis for the diagnosis of thyroid nodules.Endocrinologists should grasp the indications of FNAB.When the pathological finding is unable to distinguish between benign and malignant nodules,molecular or genetic diagnosis should be adopted for further diagnosis.Appropriate treatment is selected according to the definitive results.In this article,we share the whole process that one case with thyroid nodule was diagnosed as papillary thyroid carcinoma and eventually treated with surgery,so as to make clinicians pay more attention to thyroid nodules with standardized clinical diagnosis and treatment.

To investigate the association of HLA-A0205 and HLA-A30 with latent autoimmune diabetes mellius in adults (LADA) in Chengdu Hans, 121 subjects (41 cases of LADA, 40 cases of T2DM, and 40 normal controls) were enrolled in the study. The frequencies of HLA-A0205 and HLA-A30 were determined by nested PCR-SSP and direct sequencing, respectively. The allele frequencies of patient groups and of normal controls were compared by chi-square test using SPSS 11.0 (alpha = 0.05). Hardy-Weinberg equilibrium was tested with use of software HWE (alpha = 0.05). Data from the subjects showed: HLA-A0205 was present in 1 patient with LADA and in 1 normal control (2.44% and 2.5%, respectively), HLA-A30 was present in 2 patients with LADA, in 2 patients with T2DM and in 1 normal control (4.87%, 5.0% and 2.5%, respectively). There was no statistically significant difference between the allele frequencies of the three groups. These results suggest that HLA-A0205, HLA-A30 may not be related to LADA in Chengdu Hans. Yet, further studies with larger sample size may be needed to warrant this conclusion.
