Objective To analyze the clinical characteristics and prognosis of acute pyelonephritis (APN) in children.Methods A retrospective analysis was performed in 230 pediatric patients with APN admitted from January 2009 to December 2010.The clinical characteristics,etiology,drug-resistant and prognosis were reviewed,and logistic regression analysis was performed to identify the risk factors of renal scarring after APN.Results Among 230 patients with APN,93 were boys and 137 were girls with a malefemale ratio of 1∶ 1.47.Ninety-nine patients were younger than 1 year with a male-female ratio of 1.30∶1 ;75 patients were 1 to 5 year with a male-female ratioof 1 ∶ 2.75 ; 56 patients were older than 5 year with a male-female ratio of 1∶2.29.A total of 106 strains were detected,in which 91 strains were Gram-negative bacteria,13 strains were Gram-positive bacteria and 2 strains were fungus.The most frequent bacteria were Escherichia coli (65 strains,61.32％),Klebsiella pneumonia (13 strains,12.6％) and Enterococcus faecium (9 strains,8.49％).Forty-four strains of Escherichia coli produced ESBLs,and all of them were resistant to ampicillin,part of them resistant to cephalosporin,compound sulfamethoxazole and aztreonam,but all were sensitive to amikacin,amoxicillin/clavulanic acid,nitrofurantoin,and imipenem.Renal emission computed tomography (ECT) was performed again in 52 children who were followed up for 6-12 months,in which 31 cases (59.62％) developed renal scar,and 21 cases (40.38％) were recovered.Abnormalities in urinary system or vesicoureteric reflux were identified as the risk factors for renal scarring after APN (OR =6.89,P ＜ 0.05).Conclusions The incidence of APN in children drops with age,which is frequently in the males younger than 1 year,and in the females older than 1 year.Escherichia coli is the most frequent pathogen of APN in children,and most strains are multidrug resistant.Children with abnormalities in urinary system or vesicoureteric reflux are prone to develop renal scarring.

Objective To investigate effect of Rho kinase combined with Sheng Mai injection on tumor necrosis factor alpha ( TNF-α) , interleukin-10 (IL-10), intercellular adhesion molecule-1 (ICAM-1) and adhesion molecule CD11/CD18 in patients withⅡ°superficial burn.Methods 48 cases patients withⅡ°superficial burn were collected and divided into experimental group and control group, according to different therapy, 24 cases in each group.The two groups were given symptomatic treatment such as anti-infectious, keep warm, anti-shock, pain-relieve and wound-healing treatment, the control group were given Rho kinase on the basis of symptomatic treatment, and experimental group were given Sheng Mai injection on the basis of control group, for a course of two weeks.The serum TNF-α, IL-10, ICAM-1 and CD11/CD18 levels were compared after treatment. ResuIts After treatment, the serum TNF-α, IL-10, ICAM-1 and CD11/CD18 levels after treatment were lower than those before treatment in two groups (P<0.05).Compared with control group, the levels of TNF-α, IL-10, ICAM-1 and CD11/CD18 were lower than those of experimental group (P<0.05).ConcIusion Rho kinase combined with Sheng Mai injection could significantly reduce the levels of TNF-α, IL-10, ICAM-1 and CD11/CD18 in patients with Ⅱ°superficial burn.

Objective To compare the clinical effects of closed reduction and intramedullary nailing versus open reduction and plate fixation in the treatment of displaced midshaft clavicular fractures.Methods A prospective,randomized,controlled trial was performed between July 2012 and May 2014 in 194 patients with acute displaced midshaft clavicular fracture.They were 136 males and 58 females,from 16 to 65 years of age.They were randomly divided into 2 groups to received either closed reduction and intramedullary nailing (n =98) or open reduction and plate fixation (n =96).We recorded operation time,intraoperative blood loss,hospitalization expenses,fracture healing time and complication rate.Functional assessments were conducted at 3,6 and 12 months using the Disabilities of the Arm,Shoulder and Hand (DASH) and Constant-Murley scores.The preoperative general data showed no statistical significance between the 2 groups (P ＞ O.05).Results All the 194 patients were followed up for 12 to 27 months (average,15.6 ±3.1 months).The operation time (27.7 ± 16.3 min),intraoperative blood loss (18.6 ± 14.4 mL),hospitalization expenses (12,462.0 ±3,263.4 yuan),and fracture healing time (12.1 ± 3.0 weeks) in the intramedullary nailing group were significantly better than those(62.3 ± 19.4 min,40.3 ± 17.4 mL,24,760.0 ± 3,320.4 yuan,and 16.9 ± 2.8 weeks) in the plate fixation group (P ＜ 0.05).At 3 months after surgery,the DASH (13.4 ± 3.5) and Constant-Murley (88.5 ±5.9) scores in the plate fixation group were significantly better than those (24.8 ± 6.7 and 69.1 ± 6.2,respectively) in the intramedullary nailing group (P ＜ 0.05).At 6 and 12 months after surgery,there were no significant differences in the Constant-Murley scores or DASH scores between the 2 groups (P ＞ 0.05).The complication rate in the intramedullary nailing group (25.5％,25/98) was significantly higher than in the plate fixation group (9.4％,9/96) (P ＜ 0.05).Conclusions In the treatment of displaced midshaft clavicular fractures,compared with open reduction and plate fixation,closed reduction and intramedullary nailing has advantages of less invasion,lower cost and faster fracture healing,but a disadvantage of higher complication rate.The 2 treatments may lead to similar functional recovery of the shoulder.

Objective To investigate the safety and efficacy of endoscopic varices ligation(EVL) plus endoscopic varices sclerotherapy(EVS)for esophageal varices hemorrhage in patients with liver cirrhosis. Methods Fifty?two liver cirrhosis patients with esophageal varices bleeding were randomly divided into EVL group(n=24)and EVLS group(n=28)according to random numbers generated by computer after first EVL. The EVL group continued undergoing EVL, and the EVLS group was treated by EVS. The interval of treatment was 2 weeks till varices disappeared. All patients were followed up for 18 months with endoscopy and endoscopic ultrasonography(EUS). The efficacy,changes of esophageal varices and perforating veins, varices recurrence and rebleeding were observed. Results There was no significant difference of complete cure rate between EVLS group and EVL group[67.9%(19/28)VS 62.5%(15/24),P>0.05]. The mean session of treatment(2.68±1.0 VS 1.83±0.7,P<0.05), and perforating veins obliteration rate after treatment in EVLS group was higher than that in EVL group[70.8%(17/24)VS 23.8%(5/21),P<0.05]. During 18 months of follow?up,there was no significant difference of rebleeding rate between the two groups[3.6%(1/28)VS 12.5%(3/24),P>0.05],and the varices recurrence rate was higher in EVL group than that in EVLS group[77.3%(17/22)VS 44.0%(11/25), P<0.05]. Child?Pugh class B patients in EVL group had a higher varices recurrence rate compared to that in EVLS group[75.0%(9/12)VS 31.5%(5/16), P<0.05]. Endoscopic recurrences occurred in patients with non?occlusive perforating veins. Conclusion EVL plus EVS sequential procedure is safe and effective for treatment of esophageal varices hemorrhage,especially for Child?Pugh class B patients.Perforating veins may play a key role in the development of esophageal varices and recurrence after endoscopic therapy. EUS findings can direct the endoscopic therapy and predict the variceal recurrence.
