The aim of this study was to investigate the value of pirarubicin (THP) photosensitizer fluorescence cystoscopy for the early diagnosis of bladder cancer. From January 2012 to June 2015, 25 patients with painless gross hematuria, were injected with THP 15 min prior to surgery and subsequently underwent fluorescence cystoscopy examination. Locations of tumors were recorded and biopsies were perf...

Levo-tetrahydropalmatine (l-THP) is an alkaloid purified from the Chinese herbs Corydalis and Stephania and has been used in many traditional Chinese herbal preparations for its sedative, analgesic and hypnotic properties. Previous studies demonstrated that l-THP has antagonistic activity on dopamine receptors; thus, it may have potential therapeutic effects on drug abuse. However, whether l-TH...

Two novel compounds, 2-methyl, 4-carboxy, 5-hydroxy-3,4,5,6-tetrahydropyrimidine (THP(A] and 2-methyl, 4-carboxy-3,4,5,6-tetrahydropyrimidine (THP(B] have been identified in the pool of Streptomyces parvulus by in vivo and in vitro studies. 13C and 15N were introduced into the compounds by feeding S. parvulus with 15N- and 13C-labeled L-glutamate. High resolution 13C and 15N NMR have been appli...

Levo-tetrahydropalmatine (l-THP) is an active constituent of herbal preparations containing plant species of the genera Stephania and Corydalis and has been approved and used in China for a number of clinical indications under the drug name Rotundine. The pharmacological profile of l-THP, which includes antagonism of dopamine D1 and D2 receptors and actions at dopamine D3, α adrenergic and sero...

Gouty arthritis is characterized by the deposition of monosodium urate (MSU) within synovial joints and tissues due to increased concentrations. Here, we elucidated role natural compound cichoric acid (CA) on MSU crystal-stimulated inflammatory response. The THP-1-derived macrophages (THP-Ms) were pretreated with CA then stimulated suspensions. protein levels p65 I?B?, activation NF-?B signalin...

Intravesical chemotherapy is an important part of the treatment for superficial bladder cancer. However, the response to it is limited and its side effects are extensive. Functional single-walled carbon nanotubes (SWNT) have shown promise for tumor-targeted accumulation and low toxicity. In the present study, we performed in vivo and in vitro investigations to determine whether SWNT-based drug ...

To elucidate the differentiation-associated expression of enzymes catalyzing arachidonic acid metabolism, we measured arachidonate metabolites by reverse-phase high pressure liquid chromatography in monocytoid leukemia (ML-1, THP-1, and U937) and myeloid leukemia (KG-1) cell lines. Undifferentiated ML-1 or THP-1 cells produced trace amounts of eicosanoids via the cyclooxygenase (COX) and lipoxy...

In the present study we investigated whether endothelial microparticles (EMPs) can bind to monocytic THP-1 cells and modulate their procoagulant properties. Using flow cytometry, we demonstrated that EMPs express adhesive receptors similar to those expressed by activated endothelial cells. Expression of endothelial antigens by THP-1 cells incubated with EMP was shown by immunoperoxidase stainin...
