[Clinical follow-up study of ulnar styloid fractures and classification of distal radial fractures].
To analyze the result of the distal radial fractures with or without ulnar styloid fracture. ⋯ ORIF with locking plate in distal radial fracture is safe and effective. There is no significant difference between the outcomes of patients with and without ulnar styloid fractures, also in patients with type I and type II fractures, union or nonunion of fractures, according to the X-ray measurement and Garlant-Werley wrist function scores. However, long-term following-up is still needed.

[Biomechanical study of interspinous fixational effect on the stiffness of adjacent segments].
To discuss the effect of interspinous fixation (Wallis) on the stiffness of adjacent segments by biomechanical measurements. ⋯ After interspinous (Wallis) fixation, the stiffness and the stability of the cephalad adjacent segment increased. The interspinous fixation system (Wallis) has a protective effect on cephalad adjacent segments.

[Retrospective analysis of effect of type 2 diabetes mellitus on lumbar intervertebra disc herniation].
To analyze the influence of type 2 diabetes mellitus on incidence and severity of lumbar disc herniation. ⋯ People who received operation with lumbar disc herniation had the higher ratio concomitant with type 2 diabetes mellitus than the control group. Type 2 diabetes mellitus may increase the risk of suffering from lumbar disc herniation.

Ketamine is widely used as an anesthetic during surgical procedures in both animals and humans. As its unique effects of inducing the dissociative hallucinatory,vivid dreams, out-of-body experiences, and delirium, it has diverted from legitimate uses to the illicit drug market, and abusing ketamine has become a serious social problem. The abusers may use ketamine alone or mixe it with other drugs to get an intense pleasure. ⋯ There is no universally recognized treatment protocols for this syndrome. Ketamine cessation or even reduction is the most effective treatment to prevent deterioration of the urinary tract, and intravesical instillation of hyaluranic acid (cystitstat) and oral pentosan polysulphate (elmiron) may take effect. The pathogenesis of ketamine-associated urinary tract destruction is unclear, and further study is needed.

Review[Research progress in the relationship between TRPV1 and visceral hypersensitivity in functional gastrointestinal diseases].
Transient receptor potential vanilloid 1(TRPV1) is a nonselective cation channel with high permeability for Ca(2+). It may play a role in the development and maintenance of visceral pain and hypersensitivity states, which has generated a major interest in the development of specific vanilloid antagonists. In this review, a summary of the contribution of TRPV1 in the development of visceral hypersensitivity in functional dyspepsia and irritable bowel syndrome is presented with the structure, location, and related molecular mechanisms.
