Non-steroidal anti-inflammatory drugs are commonly used anti-inflammatory analgesics in clinic. Indomethacin is a kind of NSAIDs and has anti-tumor effect. It can significantly change the growth cycle of cancer cells, inhibit their proliferation. In this paper, the antineoplastic effect of indomethacin and its pharmacokinetic effect were analysed. The result showed that indomethacin had more metabolic distribution in tumor tissues and reached its peak at 4 hours, after that, the clearance rate was slower than that in the blood, with the clearance rate slowest at 6-12 hours. At the same time, the expression of Bcl-2 protein in cancer cells was significantly reduced and weakened, while the expression of Bax protein did not change significantly. Pharmacodynamic studies have proved that IN (Indomethacin) has a strong anti-tumor effect. It can enter into tumor cells through cell membrane and nuclear membrane to have an anti-tumor effect.The current work is documented to investigate the actions of azithromycin on intestinal smooth muscles as there are reports of gastrointestinal upsets with use of azithromycin. Azithromycin was tested on rabbit's jejunal and rat's ileal preparations in test concentrations (μM) of 0.01, 0.03, 0.1, 0.3, 1, 3, 5, 10 and 15μM. After mounting the tissues in organ bath containing Tyrode's solution, spasmogenic activity of azithromycin was observed. To explore its possible mechanisms, response of azithromycin was noted in the presence of 0.3μM atropine, 3μM loratadine, 0.3μM ondansetron, 10μM metoclopramide, 0.3μM verapamil, 1μM propranolol, 3μM amiodarone and combination of 0.3μM each atropine, ondansetron, verapamil and propranolol (AOVP). Mean % Emax for azithromycin was 67.6±1.6 and 54.0±2.1 (% of ACh max) for rabbit's jejunal and rat's ileal preparations, respectively. The Mean % Emax for azithromycin in the presence of various antagonists for rabbit's jejunal and rat's ileal preparations was as 2.4±0.1 and 11.4±1.3 with atropine; 67.9±2.0 and 50.7±1.9 with loratadine; 27.5±0.5 and 34.0±2.9 with ondansetron; 88.4±1.2 and 79.1±3.8 with metoclopramide; 13.6±1.2 and 22.3±2.5 with verapamil; 10.2±2.1 and 15.6±1.4 with propranolol; 68.4±1.3 and 58.0±3.4 with amiodarone. Results reveal that the spasmogenic response of azithromycin is mainly mediated through muscarinic receptors. However, we found involvement of mixed pathway including serotonergic receptors, voltage gated calcium channels and voltage gated sodium channels.To carry out a preliminary clinical trial to compare the effectiveness and safety of pemetrexed based chemotherapy regimen in combination of cisplatin versus ramucirumab plus erlotinib in Chinese patients with metastatic non-small-cell lung cancer (NSCLC). Patients with confirmed diagnosis of NSCLC were randomly (11 ratio) grouped and treated intravenously with a mixture of pemetrexed (500 mg/m2) and cisplatin (75 mg/m2) plus Best Supportive Care (BSC), or ramucirumab (8 mg/kg) intravenously (IV) + erlotinib 25 mg/day. Overall survival (OS), overall response rate (ORR), progression free survival (PFS), and the safety were assessed. Pemetrexed based chemotherapy regimen in combination of cisplatin showed significantly higher OS (14.4 months vs. 10.47 months, p less then 0.05) and PFS (9.5 months vs. 5.1 months) than ramucirumab plus erlotinib. Cyclopamine Objective response was also favorable in the patients treated with pemetrexed based chemotherapy regimen, when compared with those given ramucirumab plus erlotinib. Pemetrexed based chemotherapy regimen found more effective to ramucirumab plus erlotinib in improving OS, PFS and ORR, and it offers greater clinical benefits than ramucirumab plus erlotinib in Chinese NSCLC patients. Pemetrexed based chemotherapy regimen in combination of cisplatin appears to be better choice of drug for the treatment of Chinese patients with advanced stage of lung cancer.Opioid analgesic (OA) addiction occurs frequently among the elderly, and results in high morbidity and mortality due to geriatric pathologies associated with pharmacokinetic modifications. However, patients with this type of addiction are under-identified and specific screening tools should be more widely used to detect the risk factors for OA addiction. Before initiating an opioid prescription, exhaustive research into associated treatments (to track drug interaction) and opioid prescriptions by other clinicians (a phenomenon known as "doctor shopping") is required. Specific specialist care, as has been developed in the United States, is still scarce in France and treatment is provided through collaboration between geriatricians and psychiatrists. Optimisation of the treatment of somatic and psychiatric comorbidities is key to effective management.Insomnia is four times more frequent in patients with Parkinson's disease (PD) than in the general population. In PD, insomnia is associated with a very significant decrease in quality of life and has deleterious consequences on both patients' and caregivers' health. When insomnia is comorbid to PD, the main therapeutic response is the prescription of benzodiazepines or related drugs. As in the general population, these sedative-hypnotic molecules have very low efficacy in PD and are associated with adverse effects. They are highly addictive and are also associated with drowsiness, a risk of falling and decreased life expectancy. These side effects may in themselves be symptoms associated with PD in the absence of insomnia. In this clinical context, it is clear that sedative-hypnotic drugs are likely to potentiate these clinical symptoms in PD. We recently documented that insomnia disorder comorbid to PD is associated with the classic psychological factors that perpetuate insomnia in neurologically disease-free individuals with insomnia. These results enabled us to emphasise that target-oriented interventions, such as cognitive-behavioural therapy for chronic insomnia (CBT-i), should be considered as a treatment for insomnia comorbid to PD. As a reminder, for decades CBT-i has been considered to be the most effective first-line treatment for the management of chronic insomnia, whether or not it is associated with a comorbidity. In this context, we demonstrated the acceptability of CBT-i in the treatment of insomnia comorbid to PD and its effectiveness for the management of noctural and diurnal symptoms of insomnia associated with this neurological condition. The objective of this paper is to raise awareness among health professionals of the relevance of psychological therapies (mostly CBT) for insomnia in PD. Unlike drug treatments, these therapies are safe for patients who are already weakened by PD itself.
