Bronchial asthma （abbreviated as asthma） is one of the common chronic airway inflammatory diseases in the respiratory system， which is difficult to cure. Airway mucus hypersecretion （AMH） is an important factor leading to acute asthma attacks. Traditional Chinese medicine （TCM） possesses therapeutic advantages characterized by multiple pathways， multiple targets， and multiple links， and its mechanism of action in intervening in AMH has gradually drawn attention. TCM can effectively alleviate the symptoms of patients by intervening in asthma through methods such as eliminating phlegm and eliminating fluid retention. This review finds that the pathogenesis of asthma-associated AMH is correlated with decreased mucociliary clearance function and enhanced mucus secretion function； single TCM （such as Platycodon grandiflorum）， effective components of TCM （such as pinellia polysaccharides）， and compound prescriptions （mainly heat-clearing and phlegm-resolving prescriptions， etc.） can improve asthma-associated AMH by regulating the PI3K/Akt and JAK/STAT signaling pathways， inhibiting airway inflammatory responses， oxidative stress， and recovering the water-salt ratio of the mucus layer itself.

The growth of puberty height is affected by many factors, among which the role of sex hormones is particularly important. The height increase in puberty accounts for about 20% of the final height in adulthood. It was previously believed that the final height of patients with disorders of sexual development was impaired due to the disorder of sex hormones. However, there are more classifications and subtypes of disorders of sexual development, and the growth patterns of patients with different subtypes of disorders of sexual development are also different. This article briefly reviews puberty bone growth, the effect of sex hormones on puberty bones, the sex hormone spectrum and growth pattern of patients with common disorders of sexual development, and the effect of growth hormone therapy.

Objective:To explore the clinical effect of modified urethral anastomosis in penile reconstruction for female-to-male(FTM) transsexuals.Methods:A retrospective analysis was performed on the FTM transsexuals undergoing penile and urethral reconstruction in Second Affiliated Hospital of Naval Medical University from December 2016 to December 2020. In this method, lower abdominal flap and anterolateral thigh (ALT) flap were used to reconstruct the neophallus, and vaginal mucosa was used to reconstruct the urethra step by step. The 2 stage procedure was divided into 3 stage. During the second stage operation, a 2 cm wide flap bridge was reserved near the perineal end of the prefabricated urethral opening, which separated the prefabricated urethral from the urethra reserved at the pubic area. And the third stage urethral anastomosis was performed 6 months later. The urethral function after penile reconstruction was followed up to observe whether the patients had urinary fistula, standing urination and urethral patency.Results:A total of 6 FTM transsexuals, aged 29-40 years, were enrolled in the study. The operation was successful. Among them, the right ALT flap was used in 4 cases, and the left lower abdominal flap was used in 2 cases. In one case, partial flap necrosis was found in the distal part of the penis one week after the second stage surgery, which healed with free skin grafting after 2 weeks. During postoperative follow-up of 10-30 months, no urinary fistula occurred and all patients were able to urinate standing up, with no urethral stricture.Conclusions:The urethra was prefabricated with a lower abdominal flap or ALT flap, and then the procedure of phalloplasty and modified urethral anastomosis was performed in stages, which could reduce the incidence of urinary fistula and urethral stricture in FTM transsexuals.
