Bioinformatics and Computer Simulation Approaches to the Discovery and Analysis of Bioactive Peptides.

The traditional process of separating and purifying bioactive peptides is laborious and time-consuming. Using a traditional process to identify is difficult, and there is a lack of fast and accurate activity evaluation methods. How to extract bioactive peptides quickly and efficiently is still the focus of bioactive peptides research.

Penehyclidine hydrochloride on postoperatively cognitive function.

There are many drugs that affect postoperative cognitive function in patients under general anesthesia. Pentanethaquine hydrochloride (PHC), as a new type of anti-cholinergic drug, has been widely used. In clinical practice, many patients, especially elderly patients, have suffered from obvious postoperative cognitive dysfunction, but the incidence of pulmonary infection, reduced probably due to the decease of secretion production.

Regulation of Circadian Clock Genes on Sleep Disorders in Traumatic Brain Injury Patients.

Background: In patients with traumatic brain injury (TBI), whether sleep disorder is associated with disturbances in molecular rhythmicity is unclear. This study aimed to investigate the relationship between abnormal sleep and regulation by circadian rhythms in patients with TBI.

Methods: We sampled buccal cells and human blood samples from patients with TBI diagnosed with sleep disorders and those with normal sleep and investigated differences in the expression levels of Clock, Per2, and Bmal1 between the 2 groups.

Objective: To explore the eyelid's characteristics of outpatients who visited the plastic surgery clinic in 3rd Hospital of Peking University.

Methods: From Jan. 2007 to Feb.

Augmentation rhinoplasty with expanded polytetrafluoroethylene and prevention of complications.

Objective: To optimize the long-term results and reduce complications of augmentation rhinoplasty using expanded polytetrafluoroethylene (e-PTFE).

Methods: There are certain key principles. The implant should be shaped to conform to the contour of the underlying nasal structure.
