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.

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 establish a HPLC method for the determination of Paeonol in Yuxianling granules. METHODS: The determination was performed on Phenomenex C18-ODS with mobile phase consisted of methanol-water (60∶40) at a flow rate of 1.0mL?min-1. The detection wavelength was set at 274nm. RESULTS: The linear range of Paeonol was 8.24～41.20?g?mL-1(r=0.999 7). The recovery was 99.50% (RSD=1.12%). CONCLUSION: The established method is simple, rapid, sensitive, accurate, stable and reproducible, and suitable for the determination of the content of paeonol in Yuxianling granules.

Objective To evaluate the diagnostic value of magnetic resonance enterography(MRE)and ectopic gastric mucosa imaging(EGMI)in children with lower gastrointestinal hemorrhage.Methods The clinical data including gender,age,amount of bleeding and preoperative minimum hemoglobin(Hb)levels of 54 children with lower gastrointestinal hemorrhage were collected,who received surgical exploration in Department of Pediatric Surgery,Anhui Provincial Children's Hospital between February 2014 and April 2016.Children were divided into lesion group and non-lesion group according to the findings of surgical exploration.Lesion group were defined as children with Meckel's diverticulum(MD)or duplication of the small intestine by surgery and postoperative pathological findings.A total of 36 cases,25 cases of boys,11 cases of girls,aged(2.86±1.59)years old.Non-lesion group were defined as children,who underwent operation with negative result or with lesions but not MD or duplication of the small intestine.A total of 18 cases,14 cases of boys,4 cases of girls,aged(3.87±1.62)years old.MRE and EGMI were performed when the children stopped bleeding,before the inspection,should fasting for 4-6 h.SPSS 13.0 software was used for statistical processing.The evaluation of EGMI,MRE and the both in diagnosing MD or duplication of the small intestine were conducted by receiver operating characteristic curve(ROC).According to the principles of biggest gain best diagnostic value by Youden index,and the degree of sensitivity and specificity was calculated at this time,P<0.05 for the difference was statistically significant.Results There was no significant differences statistically in gender between 2 groups(x2=0.415,P>0.05).There were statistically significant differences in age,amount of bleeding and preoperative minimum hemoglobin levels(t=2.179,2.027,2.222,all P<0.05).There were statistically significant differences in classification comparison by EGMI and MRE between 2 groups(x2=15.226,29.121,all P<0.01).The optimal cut-off value of EGMI and MRE in the diagnosis of enteric malformation was more than level 3,and the suspected positive and being positive value was assigned as positive results.According to the cut-off value above,EGMI,MRE and EGMI plus MRE in series and in parallel in the diagnosis of enteric malformation,the areas under curves(AUC)were 0.809,0.917,0.750 and 0.847,respectively.The sensitivity was 61.1％,75.0％,55.6％and 80.6％,respectively.The specificity was 90.4％,94.4％,94.4％and 88.9％,respectively.The Youden's indexes were 0.515,0.694,0.500 and 0.695,respectively.The optimal cut-off value of age and preoperative minimum hemoglobin levels in the diagnosis of enteric malformation were 2.92 years and 80 g/L,respectively.The AUC was 0.761 and 0.672.The Youden's indexes were 0.515 and 0.333.There was no significant differences statistically in AUC compared with age,MRE and EGMI(all P<0.05).Conclusions The high diagnostic value in children with lower gastrointestinal hemorrhage is found by using MRE and EGMI.Then,MRE as a separate diagnosis method is also worthy of clinical application.
