The maximum urine flow rate (Qmax) was significantly changed in the mild group after the treatment (P<0.05); the Qmax was insignificantly changed in the moderate and severe groups after treatment (P>0.05).Conclusion Heat-sensitive moxibustion is significantly effective in treating mild-moderate bladder dysfunction due to poisonous snakebites, and it’s safe and reliable.

The concept of far lateral lumbar disc herniation was firstly reported by Abdullah in 1974. The diagnosis of far lateral lumbar disc herniation is based on the discography findings as well as on clinical manifestations. Far lateral lumbar disc herniation is a special type of lumbar disc herniation. Clinically, far lateral lumbar disc herniation is less seen than other types of lumbar disc herniation, it accounts for 0.7%-11.7% of total lumbar intervertebral disc protrusion. Although the incidence of far lateral lumbar disc herniation is lower, its symptoms are usually heavier and its protrusion sites are specific. Its treatment methods are more complex, including mainly conservative treatment, minimally invasive interventional therapy and surgical management, etc. This paper aims to make a review about the recent progress in its corresponding treatment.

Glucocorticoid is an important treatment for many pediatric diseases and it often leads to osteoporosis, osteonecrosis of the femoral head, and growth retardation. Among them, glucocorticoid-induced growth retardation has been a particular focus in the treatment of children patients, which leads to a decrease in final height. The mechanism of glucocorticoid-induced growth retardation is complex, and there is no safe and effective treatment.This article summarized the mechanisms underlying glucocorticoid-inhibited longitudinal bone growth and reviewed the potential therapeutic targets discovered in recent years.
