A method is disclosed for enhanced vaccination and genetic vaccination of mammals. The vaccination is accomplished by delivering molecules such as proteins and nucleic acids into skeletal muscle and other cells residing in the skeletal muscle in vivo. The protein or nucleic acid is first injected into the muscle at one or multiple sites. Immediately or shortly after injection, electrodes are placed flanking the injection site and a specific amount of electrical current is passed through the muscle. The electrical current makes the muscle permeable, thus allowing the pharmaceutical drug or nucleic acid to enter the cell. The efficiency of transfer permits robust immune responses using DNA vaccines and produces sufficient secreted proteins for systemic biological activity to be observed.

A new dry powder inhaler is developed as a pulmonary medicine delivery device for dispersing precise tiny dosages (10 μg-50 mg) of pure carrier-free ultra-fine powdered medicament (<5 μm aerodynamics particle size) into a patient's lung. The powder is drawn from the blister cell and dispersed through an outlet tube assisted by two air streams. The first air stream goes through a the blister cell from its upstream side, to significantly fluidize the medicament in the dose to flow upward. The second one extracts the fluidized powder from downstream of the blister cell for further deagglomeration and dispersion of the medicament powder by shear force. The rotating multi-dose blister can hold up to 60 doses, which are pre-metered with pure ultra-fine powdered medicament. So that it has higher drug loading capability in small volumes, compared to most current dry powder inhalers, which usually use some excipient. The inhaler efficiently disperse the aerosolized medicament in the air stream to the deep interior of patient's lung. The fine particle fraction (<4.7 μm) is reported to reach as high as 80% using this inhaler.

Disclosed are compounds, compositions and methods for systemic and local delivery of biologically active molecules.

A method of treating a disease involving surfactant deficiency or dysfunction in a patient's lungs is disclosed comprising the steps of providing a liquid lung surfactant composition; aerosolizing the lung surfactant composition with a vibrating aperture-type aerosol generator to form a surfactant aerosol; and introducing the surfactant aerosol into the gas flow within a circuit of a pressure-assisted breathing system coupled to the patient's respiratory system, whereby a therapeutically effective amount of said surfactant is delivered to the patient's lungs. Apparatus is also disclosed that increases the efficiency of delivery of aerosolized medicaments such as aerosolized lung surfactant.

Various injectable or insertable uterine fibroid treatment formulations are provided, which comprise a uterine fibroid treatment agent in an amount effective to cause shrinkage or elimination of uterine fibroids. The injectable or insertable formulations are typically solids, semi-solids or high-viscosity fluids. Other aspects of the invention are directed to systems and methods for treatment of uterine fibroids.

The invention discloses an IC automatic detecting braiding method and an automatic pallet type detecting braiding machine, comprising a pallet-transport device, a braiding packing device, a waste materials collecting device. A PC control system and an electrical control system as well as a pallet-separate device are arranged on the front end of the pallet transport device and an empty pallet-collect device is arranged on the back end. The braiding lead direction of the braiding packing device is vertical to the pallet-transport direction of the pallet-transport device. A face side scan device and a back side device for detecting IC as well as a catch-and-put device for catching IC from the pallet are orderly arranged in the transportation range of the pallet-transport device. The catch-and-put device is electrically connected with the PC control system and the electrical control system and is a classification catch-and-put device which can classify the ICs according to the detecting results of the face side scan device and the back side device and then send the eligible ICs to the braiding packing device and the unqualified ICs to the waste materials collecting device. The braiding machine has the advantages of good accuracy and reliability for scanning and detecting, rapid speed for braiding and packing, low composite cost and high production efficiency.

The invention discloses an intelligent logistics delivery method, an apparatus, and a system. The method includes: when it is detected that a delivery mobile client enters a network coverage of intelligent lockers, description information of a delivered item is obtained from the delivery mobile client and sent to a server in order to verify whether the delivered item is matched with the intelligent locker; a door of the locker is opened according to a door-opening instruction in verification result information returned by the server; when it is detected that the storage of the delivered item is accomplished, pick-up notification information is generated, and the pick-up notification information is sent to a reception mobile client; and when it is detected that the reception mobile client enters the network coverage of the intelligent lockers, pick-up verification information is obtained from the reception mobile client, the match between the obtained pick-up verification information and the pick-up verification information in the pick-up notification information is performed, and the door of the locker is opened if the matching is successful. According to the method, the apparatus, and the system, compared with the prior art, the delivery process can be simplified, and the delivery efficiency is improved.

The invention discloses an energy-saving heat supply system with a function of reducing the temperature of heat supply return water, and belongs to the field of improvement of energy utilization efficiency. Heat exchange can be repeatedly carried out on heat sources by multistage heat exchangers, multistage absorption heat exchange units, multistage compression heat pumps and an ice making type refrigerator, accordingly, the heat supply areas can be enlarged, and the energy utilization efficiency can be improved. The energy-saving heat supply system has the advantages that the temperature of the return water of heat supply primary pipe networks can be reduced and reach 0 DEG C, the return water contains 10% of ice particles, accordingly, route heat loss of the return water of the heat supply primary pipe networks can be reduced, the temperature difference of the return water of the heat supply primary pipe networks can be increased and reaches 118 DEG C from the original 60 DEG C, the flow rate of circulating water of the heat supply primary pipe networks can be lowered, energy consumption of circulating pumps can be reduced, heat supply flow rates of a user side can be greatly increased, the delivery efficiency of the pipe networks can be improved, the heat supply scale can be expanded, waste heat of a cooling tower can be recycled, and the like.

The Forward Path Multi-Media Management System architecture enables end user devices to share a common wireless forward path of a multicast communication architecture in which the forward path delivered content is dynamically changed or modified based on a real-time, near-real-time, or delay-time basis via aggregated reverse path feedback from at least one of a plurality of end user devices. The Forward Path Multi-Media Management System periodically or continuously aggregates the feedback input received via the reverse path (having wired and/or wireless connectivity), modifies the forward path multi-media content, and delivers this dynamically modified multi-media content to the then connected population of end user devices via a wireless forward path multicast in a repetitive closed loop fashion.
