Sixty-six patients with advanced head and neck cancer 57 of whom had failed to respond to prior irradiation, were treated according to two protocols. Group I consisted of 41 patients in relapse who received a monthly combination of bleomycin, vincristin, methotrexate and hydroxyuera. The 16 patients (in relapse) of group II received a monthly combination of bleomycin, vincristin, methotrexate and cis-DDP. Nine patients in group III (patients never treated) received the same combination as in group II. Recurrences were local and/or regional in 37 cases out of 57. Before any chemotherapy, 62 p. 100 of the relapsing patients gave negative responses to delayed hypersensitivity skin tests to recall antigens. Fifty-one p. 100 showed evidence of a nutritional disturbance. Overall objective responses were 31 p. 100 (18/41) in group I and 43 p. 100 (7/16) in group II (this difference was not significant). In group III, 8 patients out of 9 were defined as objective responders. Overall mean survival in group I and II was 5.8 months and showed no difference between the two groups. Response rate and survival were dependent on skin test responses, nutritional status and sites of recurrence. Survival of patients with metastatic recurrence was significantly higher than survival in patients with local recurrence. Toxicity was essentially dependent upon local sequelae of prior irradiation. The results of this trial indicate that despite the effectiveness of such combinations of cytotoxic drugs, the indications for palliative chemotherapy must be discussed in the light of local and general prognostic parameters.

Antibiotic resistance is a global crisis that stems from the use of antibiotics as an essential part of modern medicine. Understanding how antibiotic resistance is controlled among cells in bacterial populations will provide insights into how antibiotics shape microbial communities. Here, we describe patterns of gene expression that arise from growth on a surface either in isolation or under subinhibitory chloramphenicol exposure.

Cyclophosphamide has a certain therapeutic effect on treating systemic sclerosis (SSc), while difficulties exist in controlling severe systematic side effects and enhancing targeting capacity. Here, inspired from the natural extracellular matrix composition, we propose a cyclophosphamide-encapsulated nanogel based on dendritic polymers polyamidoamine (PAMAM) for SSc treatment. We combine bovine serum albumin and generation 5 (G5) PAMAM dendrimers with polyphenol modification to obtain nanogels featured with antioxidant and anti-inflammatory effects.

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease for which few drugs are available in clinical practice. Here, we identified novel capsaicin analogs by combining in-house chemical library screening and further structural optimization. (E)-1-(3,4-dihydroxyphenyl)-7-phenylhept-1-en-3-one (Compound 14) was found to be the most potent in inhibiting TGF-β-induced collagen accumulation, proliferation and migration in fibroblast cells.

Pulmonary fibrosis (PF) is a lethal pathological change of fibrotic interstitial lung diseases (ILDs) with abundant fibroblasts proliferation after severely or continually alveolar epithelial cells (AECs) injury. Barely therapies are helpful for PF. Here we use bleomycin intratracheally injection to model PF with or without human umbilical cord-mesenchymal stem cells (hUC-MSCs) and/or nintedanib intervention.

Pulmonary fibrosis (PF) is a chronic interstitial lung disease with a progressive damage to the air sacs and deposition of collagen fibers in the lung tissue. The study aimed to explore the effects of oil (NSO) or thymoquinone (TQ), alone or in combination with dexamethasone (DEX), on the development of bleomycin (BLM)-induced PF. Forty-two male rats were divided into seven groups: Control (CTRL); BLM, received a single dose of BLM on day 0, intratracheally; all remaining groups received BLM, as well.
