[Effects of anti-survivin oligonucleotides on growth of peritoneally implanted ovarian cancer xenografts in nude mice].

Objective: To observe the effect of anti-survivin oligonucleotides (ASODN) on the invasion and growth of peritoneally implanted ovarian cancer cell xenografts in nude mice.

Methods: Nude mouse models bearing peritoneally implanted ovarian cancer cell (SKOV3) xenografts were established and subjected to intraperitoneal injection of survivin ASODN or saline (control). The number and weight of the intraperitoneal xenografts were compared between the two groups.

Isolated tubal torsion in the third trimester of pregnancy: A case report and review of the literature.

Isolated torsion of a fallopian tube in the third trimester of pregnancy is an uncommon event. Its common symptoms are lower abdominal pain, vomiting, and nausea. Because these symptoms are nonspecific, isolated torsion of a fallopian tube may be misdiagnosed, delaying treatment and the opportunity to preserve the tube.

[Effect of cyclooxygenase-2 on bone loss in ovariectomized rats].

Objective: To investigate mechanism of cyclooxygenase-2 (COX-2) in bone loss in a postmenopausal osteoporosis (PMOP) rat mode with ovarietomy (OVX).

Methods: Forty female Sprague Dawley adult rats at age of 3 months were randomly divided into 4 groups, 10 in each group, including sham-operated (sham) group, OVX group, OVX treated with nilesteriol (OVX + E) group and OVX treated with aspirin (OVX + P) group. All rats in OVX, OVX + E and OVX + P groups underwent ovarietomy under abdominal anesthesia with 10% chloral hydrate.
