Clinical Study of Traditional Chinese Medicine in the Treatment of Phlegm-dampness Intrinsic Precocious Puberty (SHJG-PP)

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Clinical Trial to Evaluate the Efficacy and Safety of Sanghe Jianghuo Granules in the Treatment of Girls Aged 5-8.5 Years With Precocious Puberty and Phlegm-Dampness Internal Accumulation Syndrome According to Traditional Chinese Medicine

Precocious puberty is characterized by the premature appearance of secondary sexual characteristics. Globally, the timing of puberty onset in children has shown a certain tendency to advance. In China, the incidence of precocious puberty has been increasing year by year. Precocious puberty exerts long-term and systemic impacts on children's health: advanced bone age leads to short stature; earlier sexual development than peers may induce emotional problems such as anxiety and inferiority; it may increase the risk of obesity and type 2 diabetes, posing long-term hazards to cardiovascular health; it may also result in irregular menstruation or dysmenorrhea, exerting indirect effects on reproductive health.

Modern traditional Chinese medicine (TCM) holds that: various factors lead to liver-kidney yin deficiency, hyperactivity of ministerial fire, and early arrival of tian gui (the substance responsible for promoting growth, development and reproduction), thereby triggering premature sexual development. The main syndrome types identified in clinical practice include yin deficiency with fire hyperactivity syndrome, liver stagnation transforming into fire syndrome, and phlegm-dampness internal accumulation syndrome.

Since the late 1970s, the investigators' department has taken the lead in treating precocious puberty with TCM diagnostic methods, proposing that the pathogenesis of precocious puberty lies in "kidney yin deficiency and hyperactivity of ministerial fire", and adopting the therapy of nourishing yin and purging fire for its treatment. A number of studies have confirmed that TCM medicines with the effects of nourishing yin and purging fire can effectively alleviate the yin deficiency with fire hyperactivity syndrome in children, delay the development of secondary sexual characteristics and bone age.

At present, central precocious puberty is mostly treated with gonadotropin-releasing hormone analogs (GnRHa). However, this treatment has the drawback of inhibiting the growth axis, yielding limited benefits for children with advanced bone age, overweight or obesity, and may even affect glucose and lipid metabolism. Moreover, some children with precocious puberty complicated with obesity may be intolerant to this therapy. In contrast, TCM therapy and integrated TCM-Western medicine therapy can effectively delay the development of secondary sexual characteristics and advanced bone age, and improve final adult height, thus being widely applied in China.

Although a large number of relevant studies have been reported in recent years and TCM diagnosis and treatment guidelines for precocious puberty have been formulated, there is still a lack of high-quality evidence-based medical research to support the advantageous aspects of integrated TCM-Western medicine diagnosis and treatment. Additionally, the underlying mechanisms of diagnosis and treatment for different syndrome types of precocious puberty remain insufficiently studied.

In this study, the investigators will conduct a multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the effects of Sanghe Jianghuo Granules on the regulation of the hypothalamic-pituitary-gonadal (HPG) axis, metabolic homeostasis and inflammatory microenvironment, so as to verify its efficacy and safety. Furthermore, combined with transcriptomics, proteomics and network pharmacology, the investigators will identify the key targets and action pathways of Sanghe Jianghuo Granules, and verify its regulatory effect on the HPG axis through in vivo and in vitro experiments.
