Abstract: A fracturing manifold skid and a fracturing manifold skid set are provided. The fracturing manifold skid includes a skid base assembly and a first manifold assembly. The first manifold assembly is installed on the skid base assembly and includes a first transport pipe and a second transport pipe, and a first connecting pipe and a second connecting pipe. The first connecting pipe is connected with the first transport pipe at a first position and connected with the second transport pipe at a second position; the second connecting pipe is connected with the first transport pipe at a third position and connected with the second transport pipe at a fourth position. The first transport pipe is provided with a first valve located between the first and third positions; the second transport pipe is provided with a second valve located between the second and fourth positions.

Abstract: The invention discloses a pharmaceutical composition used in photodynamic therapy for cancer or precancerous lesions. The composition includes four isomers of zinc phthalocyanine. Furthermore, this invention also provides an industrial chromatography preparation process. The composition is synthesized by separating 10 cis-isomers from disulfonic acid diphthaloyl iminomethyl zinc phthalocyanine, and then separating among them 4 isomers with significant amphiphilic property. It is evident that the composition of the invention shows improved performance compared to compositions containing those 10 cis-isomers.
