Mechanism of Huayu Jianpi Fangshi decoction in urolithiasis prevention: a randomized trial.

BACKGROUND: This study aims to explore the mechanism of the Huayu Jianpi Fangshi decoction in urolithiasis prevention. METHODS: The present study was designed as a randomized, double-blinded, placebo-controlled clinical trial. Sixty patients with the qi stagnation and blood stasis, spleen deficiency, and dampness obstruction types of urolithiasis were randomly divided into two groups: the treatment group and the control group (n=30 in both groups). Patients in the treatment group were treated with the Huayu Jianpi Fangshi decoction, while patients in the control group were treated with the Huayu Fangshi placebo decoction. Both treatments were taken orally two times per day. All patients received treatment over the course of four weeks. The main outcome indicators included the Tamm-Horsfall protein (THP) expression levels, osteopontin, and inter-α-trypsin inhibitor heavy chain 3 (ITIH3) in the patients' urine as well as changes in 24-h urinary citric acid, urinary magnesium levels, and Traditional Chinese Medicine (TCM) syndrome scores. RESULTS: The results of the present study revealed a significant increase in the total citric acid excretion level (244.75±59.62 vs. 297.48±57.91 mmol/L, P<0.01), significant decrease in the total urinary THP level (10.83±7.73 vs. 6.37±6.10 mg/L, P<0.05), significant decrease in the total ITIH3 level (9.51±6.32 vs. 6.14±4.46 mg/L, P<0.05) in the patients' 24-h urine, and a significant elevation of the total TCM syndrome score (5% vs. 23%, P<0.01) in the treatment group when compared with the control group. CONCLUSIONS: The Huayu Jianpi Fangshi decoction can increase the excretion of urinary citric acid, decrease the expression levels of urinary THP and ITIH3 in patients with cured urolithiasis, and reduce the TCM syndrome score.

[Recognition and thoughts for diagnosis and treatment of chronic prostatitis in integrated traditional Chinese and Western medicine].

The etiology, pathogenesis, and diagnostic criteria of chronic prostatitis were reviewed in this article. Based on clinical practice, the authors systematically discussed the thoughts and methods for the treatment of chronic prostatitis by integrated traditional Chinese and Western medicine. Meanwhile, advice on disputed problems in clinical study of prostatits were given, such as curative effect estimation value of the number of leukocytes in expressed prostatic secretion (EPS) and bacterial culture in EPS, the opportunity and treatment course of antibiotics, National Institutes of Health chronic prostatitis symptom index, classification of syndromes of traditional Chinese medicine (TCM), TCM symptom score, and clinical study period.
