Hepatic cirrhosis is considered a severe health problem in Mexico, since it is the third mortality cause in working-age people and there is no 100% effective treatment. Cirrhosis is characterized by an exacerbated increase of collagen in liver parenchyma, replacing the hepatocytes and thus provoking liver failure. This is one of the reasons why we have used a gene therapy through specific delivery to cirrhotic livers of the gene of human urokinase plasminogen activator (huPA), which activates mechanisms that induce the degradation of excess cellular matrix and stimulate hepatocyte proliferation, obtaining thus a fast re-establishment of the liver function. In the instant invention, the modified human uPA gene was inserted in the adenoviral vector (pAd-DeltahuPA), because it is not secreted and does not provoke hypercoagulation or spontaneous internal bleedings. Moreover, data from the bio-distribution essay with an adenoviral vector with reporter gene beta-gal have shown liver specificity as the target organ of the vector. Using ELISA, huPa protein was detected in liver homogenates (4500 pg/ml) in animals treated with pAd-DeltahuPA and was also intracellularly detected through immunochemistry in liver cuts (80% positive cells). huPa induced a dramatic fibrosis reduction (85%) on day 10 of vector administration, compared to control cirrhotic rats and 55% hepatocyte proliferation increase. Liver function tests (ALT, AST, alkaline phosphatase and bilirubin) dropped to nearly normal levels and hepatocyte proliferation was observed. Because of the two beneficial event cascades, gene therapy with modified huPA can be developed as a definite potential treatment for patients with liver cirrhosis.

The invention provides a microneedle for hypertrophic scars and a preparation method for the microneedle. The preparation method comprises the following steps of adopting crystalline macromolecules which serve as first polymers, casting a first solution into a die with a micropore array, and performing vacuumizing to obtain a die of which micropores are filled with the first solution; adding a second solvent into the die of which the micropores are filled with the first solution, and performing vacuumizing to obtain the microneedle for hypertrophic scars. Therefore, the prepared microneedle is hard enough to penetrate through scar tissues, and moreover, a water-soluble medicament as well as an oil-soluble medicament can be supported by the microneedle.
