Objective To investigate the necessary and feasibility of fistulous tissue-saving anorectoplasty for low anorectal malformation with fistula in children.Methods The clinical data of 67 cases of low anorectal malformation with fistula were analyzed retrospectively, there were 59 girls with rectovestibular fistula, 8 boys with rectoperineal fistula. The patients′ average age were 10 months, ran -ging from 3 months to 16 years. The clinical manifestations of all patients were intractable constipation, or out of position of anus. Cut-back procedure had been performed on 4 patients in infancy. The anterior sagittal anorectoplasty was performed in all cases.Results In all cases returned for follow-up at 3 and 6 months after operation, the longest was 8 years. The postoperative course of 65 patiens was uneventful without wound infection, and had a normal-looking perineum, other 2 cases with anal rupture in operation were with sagittal wound infection resulted from perforation in repairing anus, and formed finally rectoperineal fistula with a normal-looking anus. Sixty-four cases (95.5%) had good continence by 5-6 score, another 3 cases (1 boy, 2 girls) with intractable constipation defecated with help of Glycerinum.Conclusions The fistulous tissue-saving anterior sagittal anorectoplasty is a reliable and feasible procedure for low anorectal malformation with fistula. This operation provides good results.

AIMTo study the absorption of zedoary oil in intestine of rat.

METHODSIn situ single pass perfusion model was used and the concentrations of three components in perfusate were determined by HPLC in combination with diode array detection.

RESULTSThe P(app) s of curcumol, curdione and germacrone were all low and had no significant difference (P > 0.05) at zedoary oil concentration of 0.4, 0.8 and 1.2 mg x mL(-1) in transmucosal fluid or in four different regions of intestine of rat [duodenum, jejunum, ileum, colon]. The absorption rates of germacrone and curdione were faster than curcumol's in this study.

CONCLUSIONThe zedoary oil concentration in transmucosal fluid had no significant effect on the P(app) s within the scope of 0.4-1.2 mg x mL(-1). The absorption of curcumol, curdione and germacrone showed the passive diffusion process, and didn't contain a special absorption window.

OBJECTIVETo discuss the epidemiological and clinical characteristics of the hospitalized children with hand foot and mouth disease (HFMD) in Yantai area.

METHODSEpidemiological and clinical data of HFMD children from 2009 to 2010 were summarized and analyzed retrospectively.

RESULTSMost of the infected (94.6%) were under 5 years old and the ratio between male and female was 1.5: 1. Oral mucosal pox or ulcer as well as hand and foot rashes were observed in all 931 patients. Fever and neurological disorders occurred in 840 (90.2%) and 121 (13.0%) patients respectively. The incidence was positively correlated with air temperature (r = 0.887, P < 0.001), with a peak in April to September (88.9%). The ratio of children from countryside, total duration of fever, serum concentration of c-reacting protein (CRP) and fasting blood glucose (FBG) were significantly higher in severe cases than in those mild ones. Multivariate analysis showed longer mean duration of fever( Odds ratio [OR], 1.491; 95% confidence interval [ CI] 1.170-1.901; P = 0.001) and hyperglycemia (OR, 1.124; 95% CI 1.016-1.245; P = 0.024) were independent risk factors of severity.

CONCLUSIONChildren younger than 5 years old are susceptible to HFMD and most cases occur in April to September. The monthly incidence is positively correlated with temperature of that month. Longer duration of fever and hyperglycemia are independent risk factors for severity. Most cases could have a favorable prognosis after timely diagnosis and proper intervention.
