Objective To evaluate dynamic graciloplasty (DGP) for canine in situ anal reconstruction. Methods Seventeen dogs were randomly divided into experimental group and control group. In control group, on the stage 1, the gracilis muscle were dissected in situ, manometry performed intraoperatively; In experimental group, the gracilis muscle were dissected in situ and stimulated chronically starting 7 days postoperatively. On stage 2, abdominoperineal resection of anus and graciloplasty for anal reconstruction were performed in two groups. After 2 weeks recovery, manometry and muscular fatigue-resistant curve (MFRC) were observed while myostimulator is switched off and on. The muscle of neosphincter was biopsied. Results After chronic low frequency electrical stimulation (CLFS), the percentage of type Ⅰ fibers in the stimulation group was higher than the control group (P0.05), but functioning neosphincter pressure is different significantly (P

OBJECTIVETo establish a clinical classification of pulmonary embolism (PE), and to evaluate the optional treatment strategies for different types of PE.
METHODSFrom December 1995 to July 2001, 45 patients with acute PE were hospitalized, of which 33 received intravenous thrombolytic therapy or interventional treatment.
RESULTSMisdiagnostic rate in the 45 patients with acute PE during first visit was 62.2% and mortality rate was 28.9%. Misdiagnostic rate in acute PE patients who had undergone surgery was 82% and mortality rate was 73%. The effective rate of thrombolytic therapy was 77.7%. Clinical symptoms rapidly disappeared in massive PE patients treated with interventional therapies.
CONCLUSIONSIntravenous thrombolytic therapy is one of the most effective methods for treating acute PE. Application of interventional therapy for severe acute PE is also promising.
