This invention relates to a method for the biochemical treatment of persistent pain disorders by inhibiting the biochemical mediators of inflammation in a subject comprising administering to said subject any one of several combinations of components that are inhibitors of biochemical mediators of inflammation. Said process for biochemical treatment of persistent pain disorders is based on Sota Omoigui's Law, which states: ‘The origin of all pain is inflammation and the inflammatory response’. Sota Omoigui's Law of Pain unifies all pain syndromes as sharing a common origin of inflammation and the inflammatory response. The various biochemical mediators of inflammation are present in differing amounts in all pain syndromes and are responsible for the pain experience. Classification and treatment of pain syndromes should depend on the complex inflammatory profile. A variety of mediators are generated by tissue injury and inflammation. These include substances produced by damaged tissue, substances of vascular origin as well as substances released by nerve fibers themselves, sympathetic fibers and various immune cells. Biochemical mediators of inflammation that are targeted for inhibition include but are not limited to: prostaglandin, nitric oxide, tumor necrosis factor alpha, interleukin 1-alpha, interleukin 1-beta, interleukin-4, Interleukin-6 and interleukin-8, histamine and serotonin, substance P, Matrix Metallo-Proteinase, calcitonin gene-related peptide, vasoactive intestinal peptide as well as the potent inflammatory mediator peptide proteins neurokinin A, bradykinin, kallidin and T-kinin.

The present invention relates to pharmaceutical kits and methods to treat lung inflammation and redox imbalance in human cystic fibrosis patients using pharmaceutical compositions containing N-acetylcysteine (NAC), pharmaceutically acceptable salts of N-acetylcysteine, or N-acetylcysteine derivatives. In phase I studies, treatment with oral NAC at a dose of from about 1800 mg / day to about 3000 mg / day for a period of 4 weeks produced significant positive effects, namely, it decreased absolute numbers of white blood cells and neutrophils in the sputum and produced concomitant decreases in sputum neutrophil elastase specific activity and sputum interleukin-8 levels, suggesting an amelioration of lung inflammation in the patients. These effects were associated with an increased total GSH level in whole blood as well increased staining for reduced GSH in blood neutrophils, both of which reflect an amelioration of the redox imbalance in the patients. In ongoing phase II studies, oral NAC at a dose of about 2700 mg / day administered in double-blind manner for 12 weeks showed excellent safety and significantly decreased white blood cells in sputum as compared to placebo.

The invention relates to methods and kits for detecting the likelihood that a subject has cancer, e.g., squamous cell carcinoma, by assaying the expression levels of tumor associated genes. More specifically, the expression levels of nucleic acids or proteins can be assayed in the tumor associated genes, e.g., over-expression of beta-2 microgobulin (B2M), keratin 17 (KRT17), interleukin 8 (IL8), or annexin A2 (ANXA2), and under-expression of cytochrome p450 1B1 (CYP1B1) or laminin gamma-2 (LAMC2) can be indicative of the likelihood a subject has squamous cell carcinoma or a precancerous squamous cell disorder. The expression levels compared to standards can be indicative of the likelihood a subject has squamous cell carcinoma. The expression levels of B2M, CYP1B1, KRT17, IL8, ANXA2, or LAMC2 can also be repeatedly assayed to monitor the progression of a squamous cell neoplasia.

The present invention reports stimulatory effects of interleukin 8 (IL-8) on human osteoclast formation and bone resorption, indicating IL-8 as a potent activator of bone destruction common in metastatic bone diseases. Tumor growth and osteolysis were inhibited by anti-IL-8 antibody or antisense IL-8. Additionally, IL-8 was able to confer an osteolytic phenotype on non-osteolytic cancer cells. These results identify tumor-induced osteolysis and bone resorption as potential targets of anti-IL-8 therapy.

The invention discloses an application of mi-RNA (micro-ribonucleic acid) with an AAAGUGC seed sequence in preparing an IL8 (interleukin 8) inhibitor. The mi-RNA with the AAAGUGC seed sequence can directly target the 3' non-coding region of the mRNA of IL8, so that secretion of IL8 can be effectively inhibited, and generation of cell endogenic IL8 can be reduced. Therefore, the mi-RNA with the AAAGUGC seed sequence can be used as a cell endogenic IL8 generation inhibitor and used for preventing or treating various diseases or disease states caused by IL8 generation or increase.
