Objective To investigate the effects and complications of injection with triamcinolone acetonide acetate and Pingyangmycin on maxillofacial and perineal hemangioma. Methods Local injection with triamcinolone acetonide acetate (TAA) and Pingyangmycin (PYM) was performed to treat infant maxillofacial and perineal hemangiomas: strawberry hemangioma, cavernous hemangioma and mixed hemangioma, in 107 infants admitted to our hospital from 1996 to 2005. If the lesion did not disappear after the first treatment, the injection would be performed again every four to six weeks interval, and the total dose of TAA and PYM could not be more than 100 mg and 40 mg respectively. The injection treatment was repeated 4 times for one course and the therapeutic effects on maxillofacial and perineal hemangioma was evaluated. Results All cases were followed up for one year after local injection of TAA and PYM. The cure rate was 87.8%, the effective rate was 9.3%, and the ineffective rate was 2.8%. Conclusion The injection of TAA and PYM is a reliable and less side effect therapeutic method, and valuable for infant maxillofacial and perineal hemangioma.

Objective To explore the antibacterial activity of the baicalin injection in vitro.Methods The broth doubling dilution method has been adopted.And the minimal inhibitory concentration(MIC)and minimum bactericidal concentration(MBC)of baicalin injection on 161 common pathogenic bacteria obtained from clinical practice were determined.Results The MIC range of baicalin against clinically common pathogenic bacteria is 0.1～50mg/ml and the MBC range is 0.2～50mg/ml.The MIC and MBC against staphylococci is remarkably lower than those against other bacteria,with the MIC range of 0.1～6.3mg/ml and MBC range of 0.2～12.5 respectivel.The MIC50,MIC90 are respectively 0.4mg/ml and 0.8mg/ml.Conclusions The baicalin injection possesses various levels of inhibitory effect on manifold pathogenic bacteria,especially the antibacterial effect on the staphylococci.

Objective To report 44 cases of meta-superior position anorectal malformation in different age therapied by posterior sagittal anorectoplasty(PSARP) operation, and to discuss possibility of one-stage anorectoplasty via posterior sagittal approach in neonate. Methods The clinical data of 44 cases meta-superior position anorectal malformation,which were treated by PSARP,were studied retrospectively. Results Of 44 cases, 15 were treated by colon stoma in neonate, then PSARP was executed after 3～7 months. And the rest 29 cases (9 in neonate and 20 in 2 months～9 years) were operated with one-stage anorectoplasty via posterior sagittal approach. Among 21 children followed from post-operration 6 months to 5 years, 18 cases of defecation clinical score were fineness. Conclusion The curative effects of PSARP in neonate to meta-superior position anorectal malformation is satisfactory. If the neonate is in good condition, one-stage anorectoplasty via posterior sagittal approach could be executed in infant, and favourable defecate function could be remain.

Objective To compare the advantages and disadvantages of retroperitoneal laparoscopic sur -gery and open surgery in treatment of adrenal adenoma , in order to provide the clinical evidence for the selection of surgical treatment of adrenal adenoma .Methods 120 cases undergoing surgical treatment from Jan .2005 to Dec.2010 were randomly divided into laparoscopic group and open surgery group .Operation indicators , postop-erative recovery indicators , postoperative clinical manifestations , success of operation , complications and follow-up data were evaluated and compared between the 2 groups.Results 3 cases in laparoscopic group and 4 cases in open surgery group withdrew.The operation time, intraoperative blood loss, and blood transfusion cases were (89.6 ±18.4)min vs (124.2 ±27.3)min, (70.2 ±17.2)ml vs (205.7 ±51.9)ml, and 8 cases vs 20 cases in laparo-scopic group and open surgery group .Extubation time, starting feeding time, time of getting out of bed, and length of hospital stay were (2.8 ±1.3)d vs (4.2 ±2.0)d, (1.7 ±1.1)d vs (2.9 ±1.4)d, (2.6 ±1.2)d vs (5.1 ± 3.1)d and (6.2 ±3.1)d vs (13.5 ±5.4)d in laparoscopic group and open surgery group .Postoperative analge-sic using cases and drainage volume were 11 cases vs 43 cases, and(15.4 ±4.2)ml vs(45.1 ±12.7)ml in lapa-roscopic group and open surgery group .The difference had statistical significance (P＜0.01).The cost was simi-lar between the 2 groups(P>0.05).The open surgery group had no death or relapse within 1 year, while 5 cases in laparoscopic group converted to laparotomy , with 1 case of death and 2 cases of relapse within 1 year.The complications incidence was 3.51%(2/57)in laparoscopic group, obviously lower than 16.07%(9/56)in open surgery group(P＜0.01).Conclusions Compared to the traditional open surgery, retroperitoneal laparoscopic sur-gery has advantages of less trauma, fewer complications, and faster postoperative recovery in treatment of adrenal ade-noma.Experience and skills of surgeon need to be improved to reduce the possibility of failure or recurrence .
