Recent advances in the precision control strategy of artificial pancreas.

The scientific diagnosis and treatment of patients with diabetes require frequent blood glucose testing and insulin delivery to normoglycemia. Therefore, an artificial pancreas with a continuous blood glucose (BG) monitoring function is an urgent research target in the medical industry. The problem of closed-loop algorithmic control of the BG with a time delay is a key and difficult issue that needs to be overcome in the development of an artificial pancreas.

[Review and experience on inter-laboratory comparisons of medical device testing].

By Reviewing the Inter-laboratory Comparisons of Medical Device Testing for 5 times, the present paper summarizes several experience and thoughts in participating in inter-laboratory comparisons, and offers some suggestions.

Current gamma knife treatment for ophthalmic branch of primary trigeminal neuralgia.

Aim: To probe into problems existing in gamma knife treatment of ophthalmic branch of primary trigeminal neuralgia (TN), and propose a safe and effective solution to the problem.

Methods: Through sorting the literature reporting gamma knife treatment of refractory TN in recent years, this article analyzed the advantages and problems of gamma knife treatment of primary TN, and proposed reasonable assessment for existing problems and the possible solution.

Results: Gamma knife treatment of TN has drawn increasing attention of clinicians due to its unique non-invasion, safety and effectiveness, but there are three related issues to be considered.
