3-Methyl-1-phenyl-4-[(Z)-phen-yl(4-acetamido-anilino)methyl-idene]-1H-pyrazol-5(4H)-one.

In the title compound, C(25)H(22)N(4)O(2), the dihedral angles between the central pyrazole ring and the phenyl and benzene rings are 37.01 (3), 75.58 (7) and 49.

[Total laparoscopic sigmoid and rectal surgery combined with transanal endoscopic microsurgery].

Objective: To investigate the feasibility and short-term outcomes of total laparoscopic sigmoid and rectal surgery combined with transanal endoscopic microsurgery(TEM).

Methods: The clinical data of 26 patients with colorectal carcinoma treated by total laparoscopic surgery with TEM between May 2010 and May 2011 in the Shanghai Ruijin Hospital were retrospectively analyzed.

Results: All the 26 operations were successfully accomplished laparoscopically.

2-(3-Hy-droxy-benzyl-amino)-acetic acid.

There are two independent 2-(3-hy-droxy-benzyl-amino)-acetic acid mol-ecules, C(9)H(11)NO(3), in the asymmetric unit of the title compound. The dihedral angle between the benzene rings of the two independent mol-ecules is 58.12 (4)°.

N-Methyl-N-phenyl-2-(quinolin-8-yl-oxy)acetamide monohydrate.

In the title compound, C(18)H(16)N(2)O(2)·H(2)O, the dihedral angle between the quinoline ring system and the benzene ring is 87.19 (8)°. In the crystal, water mol-ecules are linked to acetamide mol-ecules via inter-molecular O-H⋯N and O-H⋯O hydrogen bonds.

[Analysis of 32 patients with rectal adenoma undergoing transanal endoscopic microsurgery].

Objective: To evaluate the safety and outcomes after transanal endoscopic microsurgery (TEM)for rectal adenoma.

Methods: Data of 32 patients undergoing TEM for rectal adenoma between September 2006 and February 2010 in the Ruijin Hospital were reviewed.

Results: The adenoma diameter ranged from 0.

2-Chloro-N-methyl-N-phenyl-acetamide.

In the title compound, C(9)H(10)ClNO, the non-H atoms, excluding the phenyl group, are almost coplanar (r.m.s.
