Background: Extensive observational evidence has suggested an association between depression and type 2 diabetes (T2D). However, the causal relationships between these two diseases require further investigation. This study aimed to evaluate the bidirectional causal effect between two types of depression and T2D using two-sample Mendelian randomization (MR).

Type‑2 diabetes mellitus (T2DM) is a metabolic disease associated with insulin resistance and impaired islet β‑cell function. There is evidence that methylation of PDX‑1 plays a role in the development of T2DM.

Identifying the causes of thyroid dysfunction is critical for the subsequent selection of treatment. The free triiodothyronine to free thyroxine ratio (fT/fT) is widely used but is still a controversial diagnostic measurement.

At first, to solve the problems of delay in image system and measuring deviation in encoder, an adaptive dual rate Kalman filter technology is designed to estimate the accurate location of LED chip in real time. After sensitivity analysis, the changes of system parameters during manufacturing have a significant influence on estimation effect.

Methods: The studies were searched using PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Ser-vice Platform, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biology Medicine (CBM) up to October 2018.
Results: A total of 8 studies including 1,075 DN cases, 610 healthy controls, and 901 diabetes mellitus (DM) con-trols were involved in this meta-analysis.

A stable hepatoma cell line(Hep G2 cell) insulin resistance model was established and used to analyze the effect of effective components of Mori Folium in alleviating insulin resistance,and preliminary explore the mechanism for alleviating insulin resistance. The Hep G2 insulin action concentration and the duration of action were investigated using the glucose oxidase method(GOD-POD method) to establish a stable Hep G2 insulin resistance model. Normal control group,model group,Mori Folium polysaccharide group,Mori Folium flavonoid group and rosiglitazone group were divided to determine the glucose consumption.

Firstly, a structure of dual rate Kalman filter is introduced to the visual servo control system, which compensate the visual information delay and realize the accurate time sequential coordination of encoder and visual feedback. Then, considering the inaccuracy of system mathematical model, the adaptive forgetting factor is added to the iterative process of above algorithm, and the impact of accumulated model error on system stability is consequently mitigated.

A single factor experiment was designed and the extraction process was optimized using an orthogonal test. MKN45 cells were treated with different concentrations of flavonoid from for 24 and 48 h and the inhibitory effect on the MKN45 cells was evaluated using an MTT assay.

To find out individual risk factors in the two genotypes especially in susceptible genotype could provide more efficient and targeted prevention.
Methods: This was a prospective cohort study.
Background: Abnormal expression of serum TGF-β1 was found in patients with diabetic nephropathy. However, the association of TGF-β1 with the risk of diabetic nephropathy remains unknown. The present study was undertaken to investigate whether such an association exists.

Methods: Epidemiologic investigation on constitution adopting the "Constitution in Chinese Medicine Questionnaire" (CCMQ), and survey on syndrome type by CM syndrome scale (preliminary) were carried out in 180 DN patients. Cluster analysis on symptom items was used to determine the syndrome type, and canonical correlation analysis was used to analyze the relationship between patients' constitution and syndrome.
