Treatment of pulmonary fibrosis in one convalescent patient with corona virus disease 2019 by oral traditional Chinese medicine decoction: A case report / 中西医结合学报

After one-month of oral treatment with traditional Chinese medicine decoction, without using other drugs, the lung inflammatory exudate, pulmonary fibrosis and quality of life of a 61-year-old female patient with corona virus disease 2019 (COVID-19) were significantly improved. No recurrence or deterioration of the patient's condition was found within seven weeks of treatment and follow-up, and no adverse events occurred, indicating that oral Chinese medicine decoction was able to improve the pulmonary inflammation and fibrosis in a patient recovering from COVID-19, but further research is still needed.

4-Nitro-phenyl-hydrazinium picrate monohydrate.

In the crystal structure of the title compound, C6H8N3O2 (+)·C6H2N3O7 (-)·H2O, N-H⋯O and O-H⋯O hydrogen bonds link the components into a two-dimensional network parallel to (010). In addition, there are pairs of weak inversion-related C-H⋯O hydrogen bonds within the two-dimensional network. The three nitro groups are twisted by 1.6 (3), 7.8 (3) and 12.1 (3)° from the ring plane in the anion, while in the cation, the nitro group makes a dihedral angle of 4.6 (2)° with the ring.

{N,N'-Bis[(E)-3-phenyl-allyl-idene]ethane-1,2-diamine}dichloridozinc(II).

In the title compound, [ZnCl(2)(C(20)H(20)N(2))], the Zn(II) atom is four coordinated in a distorted tetra-hedral geometry by two N atoms of the Schiff base ligand and by two Cl atoms. Edge-to-face C-H⋯π inter-actions exist between mol-ecules, with a dihedral angle of 37.8 (1)° between the benzene ring planes and a shortest H⋯centroid distance of 3.62 (5) Å.
