Objective To explore the effect of treatment of children's stress hyperglycemia with glucose-insulin-potassium.Methods Thirty children with stress hyperglycemia were randomly divided into two groups,15 cases in each group.Patients in the treated group were admi-nistered with glucose-insulin-potassium,whereas those in the control group,glucose were transfused at the speed

Object To optimize the process for the extraction of the original recipe used in the treatment of eczema to give a new ECZEMA SPRAY dosage form Methods The extraction process was studied by orthogonal experimental design as guided by determining the content of paeonol and baicalin in the extract Results The optimal extraction process was to reflux the original recipe with 80% ethanol twice at a bath temperature of about 90 ℃ for 1 5 and 1 0 h respectively The amount of ethanol used for each extraction was 10 and 8 times of the original recipe respectively Conclusion The above extraction process gave the most rational and satisfactory results

Objective To evaluate the diagnostic value of the spectral CT imaging on the complications after breast augmentations with silicone implants.Methods A lot of 22 cases with breast implants were scanned by the Gemstone spectral imaging (GSI) CT.The original data were loaded in processed workstation, analyzed by GSI analysis software, and then stored the series we needed.The features of the complications after breast augmentations with silicone implants were reviewed retrospectively on the spectral CT images.Results A lot of 44 breast implants scanned in our study and there were 23 breast implants with complications, including 7 breast implants with capsular rupture (6 breast implants with endometrial rupture detected by spectral CT, including 4 breast implants with endometrial rupture, 3 breast implants with outer membrane rupture and leakage), 13 breast implants with capsular contracture (classification according to Baker's classification, 6 in grade Ⅰand 7 in grade Ⅱ), 8 breast implants were moved and 2 breasts had foci of calcification.Conclusions The spectral CT imaging play important role in detecting the complications after breast augmentations with silicone implants by GSI analysis software.

METHODS: The contents of ferulic acid and the amount of extract wer e used as marker, the optimium of concentration, purification and drying for pr eparation were selected by orthogonal design and contrast test during aqueous ex tract alcohol precipitation process. RESULTS: Condition was optimum of herb-to-extract ratio in the range of 0.5 ∶1, pr ecipitation with ethanol containing 40% water and drying temperature not to exce ed 60℃ . CONCLUSION: The highest yield of active priciples is obtained by c ondition above.

Objective To study the expression of Livin,a novel inhibitor of apoptosis protein(IAP)family member in children with acute lymphocytic leukemia(ALL).Methods Livin protein of 40 cases myeloid tissue of children with ALL and 20 cases that of non-leukemia children were assayed by streptomycin avidin-biotin-peroxidase complex staining immunohistochemical method in order to analyze the relationship between Livin protein expression and development of ALL.Results The positive rates of Livin protein expression was 40% in 40 cases ALL,but in control group,the positive rates of Livin protein expression was 5%.The difference of 2 groups was significant(P

Objective To study the expression of novel inhibitor of apoptosis protein(IAP) family member livin gene and its two isoforms(livin ? and livin ?) in brain tissue of children with gliomas.Methods Livin ? and Livin ? mRNA were detected by real time fluorescent quantitative reverse transcription polymerase chain reaction(RT-PCR) in brain tissue of 30 children with gliomas and 12 healthy children.Result The positive rate of Livin mRNA expression was 83.3%(25/30 cases)in 30 cases of children with gliomas,the positive rate of Livin mRNA was only 8.3%(1/12 case) in normal brain tissue,there was significant difference in 2 groups(P

Objective To evaluate the relationship between recurrent intussusception and enlarged mesenteric lymph nodes (EMLNs) in children by ultrasound.Methods A total of 35 cases (a total of 75 relapse) with imaging features of recurrent intussusception were retrospectively analysed.The sequence,size,number,morphology and location of EMLNs were recorded.Results Twenty cases of EMLNs were found in 35 cases recurrent intussusception (57.1%,20/35).At least three EMLNs were found in and / or around the mesentery of intussusception.The imaging feature of recurrent intussusception was a " target" appearance on transverse scans and a "sleeve" sign on longitudinal scans .All the EMLNs were smooth and oval-shaped hypoechoic nodule.The largest longitudinal diameter of the EMLNs ranged between 7-20 mm ,the largest transverse diameter of the EMLNs ranged between 3-8 mm with the aspect ratio≥2.0.Conclusion The Enlarged mesenteric lymph node recurrence of intussusception in children is crucial factor.Ultrasound can not only accurately and timely diagnose and treat intussusception while scanning enlarged mesenteric lymph nodes,which can provide an important basis for reducing the recurrence of intussusception.

Objective To investigate the clinical value of spinal nonfusion interspinous Coflex system for the degenerative lumbar spinal stenosis.Methods From March 2008 to August 2009,26 patients with degenerative lumbar spinal stenosis were treated by decompression with posterior spinous process and interspinous implant Coflex folder method,including 11 males and 15 females,with the mean age of 65.4years(range,45-78 years).L3,4 segment in 7 cases,L4,5 segment in 13 cases,concomitant L3,4,L4,5 segment stenosis in 6 cases.Patients were scanned by MRI and CT confirmed L3,4 and(or)L4,5 segments of the ligamentum flavum thickening,proliferation of small-joint bone,merger disc herniation causing central tube and lateral fossae stricture,nerve root or coccygeal plexus compression.Lumbar anteroposterior,lateral and flexion-extension X-ray films preoperatively,and at follow-up were used to measure the following parameters by eFilm and CAD software:the anterior and posterior disc space height,the range of motion at surgical level,and the segment of the spinal canal area of responsibility.Postoperative standard Japanese Orthopaedic Association(JOA)score for preoperative and postoperative scores.Results Patients were followed up 12-24months.The pain relieved in all patients.The JOA scores improved from(15.46 ±4.30)preoperatively to (24.50±1.58)postoperatively,the vertebral canal area of the affected segment was(218.4±16.2)mm2 before the operation,(264.6±9.9)mm2 after the operation.Single segment anterior disc space height did not change significantly,the difference was not statistically significant.The disc space posterior height increased compared with the preoperative height,and gradually decreased with time.No patients suffered Coflex loosening,fracture and emerge.Conclusion The treatment of lumbar spinal stenosis with Coflex system has satisfactory effect in minimal invasiveness and high security,which provides a safe and effective therapy for degenerative lumbar spinal stenosis.

Objective To investigate the CT manifestations of Meckel's diverticulum and its complications in children. Methods Retrospective analysis of Clinical and CT findings in 25 cases with pathologically proved Meckel's diverticulum. The unenhanced and contrast-enhanced CT were obtained in all patients. Results (1)The direct signs: the diverticulum cannot be shown in 5 cases; the diverticulums were found around the navel or in lower right abdomen in 20 cases. The blind-ending fluid-filled or gas-filled structures were found in 9 cases, with heterogeneous ring-enhancement. The tubercle-like structures were detected in 11 cases, which showed no enhancement in 4 cases, and homogeneous enhancement in 3 cases,and heterogeneous enhancement in 4 cases. (2) The indirect signs included intestine obstruction in 8 cases,swelling fat layer surrounding the diverticulum in 9 cases, free gas around the diverticulum in 3 cases,thickened mesentery in 8 cases, ascites in 4 cases, and intussusception due to inverted Meckel's diverticulum with "target sign" in 1 case. (3) CT classification: with diverticulitis or diverticular bleeding in 20 eases; with intestine obstruction or intussusception in 8 cases; bands-caused obstruction in 7 cases;intussusception in 1 case; with perforation in 3 cases. Conclusion Meckel's diverticulum and its complications have typical CT findings, and CT can clearly demonstrate diverticulum's shape, margin,internal components and surroundiug tissues.
