Objective To retrospectively study the results of endoscopic manifestation pathology,and treatment of colonic polyps. Methods Clinical data of 121 patients diagnosed with colonic polyps and treated by endoscopy between November 2002 and September 2009 were studied. Complete colonic investigation was done by Olympus PCF240I electron endoscopy. Colonic polyp excision was done by high frequency electric coagulation. Results All patients had bloody stool with mucus for 1 week to 8 years. Ninty four(77.7%)patients had a single polyp,6(5.0%)had two polyps,21(17.3%)with multiple polyps,and 5 patients had familial polyposis coli. The size of the polyps ranged from 0.3 cm to 4 cm and the morphology of Yamada Ⅰ to Ⅳ. The pathological changes were juvenile polyps,inflammatory polyps,polypoid formation,and canalicular adenoma. Most common pathology types were Yamada Ⅳ and juvenile polyps,107 of the 121 patients(88.4%)had juvenile polyps,and one was found to have malignant transformation. 115 patients accepted high frequency electric coagulation excision under general anesthesia,without complication. Conclusions Colonic polyp is one of the common diseases in children. Children should be checked by total colonoscopy in time when they present with bloody stool,anemia,rectal polyps prolapse or intussusception. Polypectomy under endoscope is a most safe and reliable treatment method when the diagnosis is confirmed. For isolated juvenile polyp,regular recheck is not necessary after polypectomy except when bloody stool recurs. Regular follow up by colonoscope is necessary for juvenile polyp combined with adenoma and adenomatous polyps. Colonoscope is necessary at any time when bloody stool occurs. Familial polyposis coli is difficult to be treated by endoscopy,thus surgical procedure is suggested.

Objective To evaluate the clinical efficacy of four different methods of laparoscopic hysterectomy: laparoscopic supracervical hysterectomy(LSH),classic intrafascial supracervical hysterectomy(CISH),laparoscopic-assisted vaginal hysterectomy(LAVH),and total laparoscopic hysterectomy(TLH). Methods A retrospective analysis was carried out on 740 cases of laparoscopic hysterectomy in this hospital from January 1999 to December 2004 in respect of operating time,intraoperative blood loss,weight of removed uterus,postoperative recovery,time to normal sexual life,sexual satisfaction,and incidence of complications. Results The operations were accomplished under laparoscope in all the 740 cases.The operating time of LSH,CISH,TLH,and LAVH were 95.3?32.4 min,84.5?31.7 min,105.3?34.5 min,and 169.4?37.4 min,respectively.The time to normal sexual life of LSH,CISH,TLH,and LAVH were 30?5 d,50?9 d,35?7 d,and 54?11 d,respectively.The incidences of complications of LSH,CISH,TLH,and LAVH were 1.7%(2/120),1.3%(4/310),2.8%(7/250),and 1.7%(1/60),respectively. Conclusions Laparoscopic hysterectomy is safe and reliable.Of four methods of laparoscopic hysterectomy,each has its advantages and disadvantages,and method selection should be based on patient's own conditions.

Objective To evaluate the possibility and curative effect of total en bloc spondylectomy (TES) for the treatment of primary tumors of the lumbar spine. MethodsBetween June 2005 and July 2009,nine cases of primary tumor of the lumbar spine were treated with total en bloc spondylectomy through a single posterior approach performed in seven cases(L1 giant cell tumor, L1 osteosarcoma, L2 giant cell tumor,L2 solitary plasmacytoma, L2 chondrosarcoma, L2 chordoma, and L3 histiocytic sarcoma), and two cases through a single stage anterior and posterior combined approach (L4 giant cell tumor with paraspinal mass and L4 fibrosarcoma). They were performed a single stage reconstruction after removing tumors of vertebra. Neurofunction was evaluated perioperatively and recurrence of tumor was tracked for all cases.ResultsThe follow up was obtained for 3-49 months (averaging 19 months). All patients attained significant clinical improvement after surgery without any severe complications. There was no local recurrence and distal metastasis in shortterm follow-up. ConclusionThe treatment by TES to remove tumors and reconstruction of spine are reliable for primary tumors of the lumbar spine. The curative effect of short-term follow-up is satisfactory. However, the long-term curative effect remain to be further follow-up.

The paeonol proniosomes ointment and ordinary ointment were administered to rats. Physiological saline served as perfused solution. The perfusion rate was 5 mL x L(-1) and the microdialysis samples were collected every 20 min intervals. The paeonol concentration in perfused solution was determined by HPLC. Investigation of the pharmacokinetics of paeonol proniosomes ointment and ordinary ointment by the skin-blood synchronous microdialysis coupled with HPLC is reported in this study. The results show that the recovery was (54.80 +/- 1.50)% in vitro and (54.58 +/- 4.61)% in vivo. The results showed that paeonol proniosomes ointment significantly raised the drug concentrations in skin more than the paeonol ordinary ointment. The paeono proniosomes ointment has less drugs into the blood as the ordinary ointments in blood, but its blood drug concentrations were steadier. The paeonol proniosomes ointment may be developed into a new preparation.
