Abstract: Disclosed are an oil-free bearing liquid supply air-conditioning system and a control method therefor. The system includes a compressor, a condenser, an evaporator, a first refrigeration liquid supply path for bearing lubrication from the condenser to the compressor, a second refrigeration liquid supply path for bearing lubrication from the condenser to the compressor, and a communication pipeline arranged between the condenser and the evaporator, the communication pipeline including a first solenoid valve. At least two refrigeration liquid pumps are arranged in the second refrigeration liquid supply path for bearing lubrication, the at least two refrigeration liquid pumps are arranged in parallel, and the at least two refrigeration liquid pumps include a main refrigeration liquid pump and at least one standby refrigeration liquid pump.

Abstract: This invention relates to single or multiple target anti-sense oligonucleotides (STA or MTA oligos) of low or no adenosine content for respiratory disease-relevant genes, composition thereof and method for manufacturing the composition. The compositions are effective in the prophylaxis and treatment of diseases and conditions associated with the up-regulated expression of one or more different combination of the genes, including airway inflammation, allergy(ies), asthma, impeded respiration, cystic fibrosis (CF), Chronic Obstructive Pulmonary Diseases (COPD), allergic rhinitis (AR), Acute Respiratory Distress Syndrome (ARDS), pulmonary hypertension, lung inflammation, bronchitis, airway obstruction, and bronchoconstriction, among others. This invention further relates to a method for screening candidate compounds useful for the prevention and/or treatment of respiratory diseases which binds to gene(s), EST(s), cDNA(s), mRNA(s), or their expresed product(s).
