[Progress on the impact of adjacent vertebral arch after single open door laminoplasty].

Single-door laminoplasty has been widely used in the treatment of multisegment cervical myelopathy, with the clinical advantages of decompression of the spinal cord, relieving preoperative neurological symptoms or signs, and maintaining cervical mobility. However, in clinical work, patients with limited cervical spine activity after single open door laminoplasty are often encountered, and the direct contact with the adjacent vertebral arch can be observed in the postoperative X-ray of the anterior and lateral cervical spine, which is called the adjacent vertebral arch bone impact, which is one of the important causes of the limited cervical spine movement. In recent years, there have been many reports on the prevention of bone impact, although the short-term clinical effect is significant, but long-term clinical efficacy to be further study, and the cause and the pathogenesis of bone impact is no consensus, this paper on the surgery of adjacent vertebral arch impact epidemiology, biomechanics, clinical performance, surgical effect and improvement.

[Relationship between obesity and lumbar disc herniation in adolescents].

Objective: To explore the relationship between obesity and lumbar disc herniation in adolescents.

Methods: From January 2018 to July 2019, 581 patients (337 males, 244 females) with lumbar disc herniation were included in the surgical treatment. According to the age classification standard of the World Health Organization, they were divided into two groups:the adolescent group, 235 cases (145 males, 90 females), age 14 to 44 years old with an average of (32.

[Bicyclol combined with ganciclovir for treatment of infantile cytomegalovirus hepatitis].

Objective: To evaluate the therapeutic effects of bicyclol combined with ganciclocir on infantile cytomegalovirus hepatitis.

Methods: Seventy infants with cytomegalovirus hepatitis were randomized into treatment group (n=35) and control group (n=35) for a 2-week-long treatment with ganciclocir (5 mg/kg) with and without oral bicyclol (3 mg/kg, twice daily), respectively.

Results: In both groups, significant changes occurred in the levels of alanine aminotransferase, alkaline phosphatase, serum total bilirubin, serum total bile acid, and glutamyl transpeptidase after the 2-week treatment (P<0.

Effect of TRPV1 gene mutation on bronchial asthma in children before and after treatment.

Bronchial asthma is a worldwide disease with high incidence. It not only harms children's physical and mental health, but it also brings a heavy burden to their families as well as the society. However, the trigger and pathogenesis of the disease remain unclear.

Preliminary study on pathogenesis of bronchial asthma in children.

Background: The etiology and pathogenesis of bronchial asthma remain unclear. This study is to investigate the risk factors related to bronchial asthma onset in children from genetics and immunology and preliminarily reveal the pathogenesis of bronchial asthma in children.

Methods: Real-time quantitative PCR was adopted to detect the expression level of TRPV1 gene and mRNA and enzyme-linked immunosorbent assay method to the total immunoglobulin E level and levels of IL-4, IL-5, and IFN-γ in serum in peripheral venous blood for children in two groups.
