Current status and temporal trend of disease burden of thyroid cancer in China from 1990 to 2019.

Objective: Thyroid cancer has been an increasingly high-profile public health issue. Comprehensive assessment for its disease burden seems particularly important for understanding health priorities and hinting high-risk populations.

Methods: We estimated the age-sex-specific thyroid cancer burden and its temporal trend in China from 1990 to 2019 by following the general methods from the global burden of disease (GBDs) 2019 Study.

The Influence of Val66Met Polymorphism in Brain-Derived Neurotrophic Factor on Stroke Recovery Outcome: A Systematic Review and Meta-analysis.

. A single nucleotide polymorphism at nucleotide 196 (G/A) in the human brain-derived neurotrophic factor () gene produces an amino acid substitution (valine to methionine) at codon 66(Val66Met). It is unclear whether carriers of this substitution may have worse functional outcomes after stroke.

[An Analysis on the Association between Lipid Metabolism and Low Birth Body Mass and Relative Factors among Rural and Urban Adolescents].

Objective: To analyze the status of lipid metabolism and the relationship between low birth body mass and lipid metabolism disorders in adolescents with different economic and cultural backgrounds.

Methods: Totally 1700 adolescents from urban and rural areas aged 12-18 years were selected in 2013. The lipid profiles were determined, and a questionnaire-based survey was conducted.

Performance comparison between Logistic regression, decision trees, and multilayer perceptron in predicting peripheral neuropathy in type 2 diabetes mellitus.

Background: Various methods can be applied to build predictive models for the clinical data with binary outcome variable. This research aims to explore the process of constructing common predictive models, Logistic regression (LR), decision tree (DT) and multilayer perceptron (MLP), as well as focus on specific details when applying the methods mentioned above: what preconditions should be satisfied, how to set parameters of the model, how to screen variables and build accuracy models quickly and efficiently, and how to assess the generalization ability (that is, prediction performance) reliably by Monte Carlo method in the case of small sample size.

Methods: All the 274 patients (include 137 type 2 diabetes mellitus with diabetic peripheral neuropathy and 137 type 2 diabetes mellitus without diabetic peripheral neuropathy) from the Metabolic Disease Hospital in Tianjin participated in the study.

[Prevalence rate of hypertension and related risk factors in populations of Tianjin].

Objective: To investigate the prevalence rates of the different subtypes of hypertension and related risk factors in adults from Tianjin.

Methods: With multi-stage randomized cluster sampling method, 20 346 people aged 18 years and over were selected from both urban and rural areas of six geographical regions in Tianjin in 2006. A cross-sectional study was conducted.

[Prevalence and risk factors of type 2 diabetes mellitus in adult obese population in Tianjin].

Objective: To investigate the type 2 diabetes mellitus (T2DM) prevalence and related risk factors in adult population with obesity in Tianjin.

Methods: With stratified cluster randomized sampling, 2888 obese people with BMI ≥ 28 kg/m(2), aged 18 years old and over were selected from three urban and three rural regions of Tianjin, in 2006. Information on risk factors was collected with questionnaire through face-to-face interview by trained workers and data on fasting blood glucose (FBG) was collected at the same time.

[Traditional Chinese medicine diagnosis and treatment of type 2 diabetes in Tianjin urban population].

Objective: To explore the traditional Chinese medicine (TCM) diagnosis and treatment of type 2 diabetes in Tianjin urban population.

Methods: A cross-sectional study was conducted on hospital patients with type 2 diabetes in TCM hospitals of different levels in Tianjin from 2003 to 2007. The multiphasic stratified cluster sampling method was adopted in selecting the target hospital.

Prevalence of impaired glucose regulation in the population of Tianjin.

Objective: To investigate the prevalence of impaired glucose regulation (IGR) in the population of Tianjin.

Methods: A cross-sectional study was conducted in Tianjin from June to September in 2005. The multi-phasic stratified cluster sampling method was adopted.
