Abstract: A cable connector includes a cable, a cover body, and a sealing member. The cable has multiple core wires and a cover layer. The cover layer covers a part of each core wire. An uncovered part of each core wire defines a naked section. The cover body covers the cover layer and a part of each naked section, and is formed with a hole corresponding to positions of the naked sections. The sealing member is disposed in the hole and seals a gap between any two of the naked sections adjacent to each other. Therefore, liquid such as water may be prevented from infiltrating into the connector along a periphery of each core wire.

Abstract: A method for calculating glomerular filtration rate (GFR) is revealed. A circumference of a patent's neck is measured and then is substituted into an exponential formula together with clinical factors and patient's age for estimating GFR. The present method has a better performance compared with methods for evaluating renal function by GFR available now. The methods available now have poor performance in prediction of loss of renal function at early stage. Some patients are diagnosed at an advanced stage so that they miss the opportunity of early treatment.
