The observation of specimens by LM and EM was made. The control group, endostatin and PF-4 experimental groups were set. Methods of the scraped line and MTT were used to examine their inhibitive effect on the lymphangiogenesis. Results The P value is

Objective To observed the clinical effect of vidarabine and interferonα-2b aerosol inhalation in the treatment of children with infantile herpangina.Methods 58 children with infantile herpangina were divided ran-domly into the observation group and control group,29 cases in each group.All children were given theroutine nursing and general supportive therapy.The patients in the control group were treated by ribavirin and those in the observation group treated by vidarabine and interferon aerosol inhalation.The fever clearance time,the disappearance time of her-pes,the days of hospitalization and cases of adverse reaction was observed and recorded.Results The cooling time, bleb disappear time and hospital stay of the observation group were lower than those of the control group,the difference were statistically significant(P <0.05).Comparation of the clinical effects of the two groups showed that the test group were significantly better than those in the control group(P <0.05).The total effective rate in the observation group was 96.6%,which was higher than 75.9% in the control group(χ2 =5.22,P <0.05).No obvious adverse e-vents took place in both groups.Conclusion Vidarabine and interferon aerosol inhalation in treating infantile herpan-gina takes a good effect,no obviously adverse reaction and is worth being widely applied in clinic.

Objective:To analyze 916 cases of endoscopically diagnozed reflux esophagitis(RE) and to explore the endoscopic and clinicopathologic characteristics of RE.Methods:Totally 916 RE patients from Lixiahe district in Jiangsu province(1997 2002) were graded with criterion made in Chinese Yantai in 1999.Some cases were subjected to pathology,age,sex,symptoms,endoscopic manifestations and pathology variety examination.Results:The incidence of RE was for 7.4% in endoscopic checked patients(916/12 376).The male to female ratio was 2.2∶1,mean age was (54.42?15.05),patients above 60 years old accounted for 46.5%.Only 32.6% of RE patients had typical reflux symptoms(426/916,299/916).Endoscopic diagnosis focused on Chinese Yantai standardⅠ Ⅱ (85.3%,781/916),pathology diagnosis focused on light to moderate degree,secondary RE was common in severe degree.Some patients were accompanied by bile reflux,esophagus gap hernia and peptic ulcer.Conclusion:The incidence of RE in Lixiahe district in Jiangsu province is rather high,it is common in middle aged and senior male patients(Ⅰ Ⅱ).Pathology variety is chiefly scalelike epithelial proliferation filled with chronic inflammatory cells.It was partly accompanied by atypical proliferation,erosion and ulcer,appearance of early cancer was occasionally found.The sensitivity of clinic symptoms diagnosis is lower than endoscopic diagnosis which is simple and of great value.

OBJECTIVE:To evaluate evidence foundation of phamracogenetics personalized medication,and to provide refer-ence for clinical application. METHODS:Using“phamracogenetics”“pharmacogenomics”and“gene polymorphism”as key words,related literatures and clinical guideline were retrieved from PubMed,CNKI,Wanfang database,and analyzed in respects of involved gene,site and drug types,etc. Evidences of package inserts of phamracogenetics biomarker were evaluated by using phamracogenetics practice and prevention evaluation guideline. RESULTS:8 276 papers,25 guidelines and 166 drug package in-serts are available for analysis. The phamracogenetics literatures mostly focus on the relationship between some one gene and differ-ent drugs. In guidelines,some one specific gene can guide clinical application of multiple drugs in different fields. In drug package inserts,general level of clinical evidence is not high;detectable biomarkers is inadequate in category,and detection rate is only 38.06% besides targeting preparation. CONCLUSIONS:Under the condition of low clinical evidence level the detection of pharma-cogenetics biomarker should be conducted carefully,and basic study should be further strengthened.

Objective To compare temperature curve and ablation zone between 915 MHz and 2450 MHz cooled shaft microwave antenna in ex vivo porcine livers.Methods The 915 MHz and 2450 MHz microwave ablation and thermal monitor system were used in this study.A total of 56 ablation zones and 280 temperature data were obtained in ex vivo porcine livers.The output powers were 50,60,70,and 80W and the setting time was 600s.The temperature curve of every temperature spot,the short- and long-axis diameters of the coagulation zones were recorded and measured.Results At all four power output settings,the peak temperatures of every temperature spot had a tendency to increase accordingly as the output power was increased,and except for 5 mm away from the antenna,the peak temperatures for the 915 MHz cooledshaft antenna were significantly higher than those for the 2450 MHz cooled-shaft antenna (P ＜0.05).Meanwhile,the short- and long-axis diameters for the 915 MHz cooled-shaft antenna were significantly larger than those for the 2450 MHz cooled-shaft antenna ( P ＜0.05).Conclusions The 915 MHz cooledshaft antenna can yield a significantly larger ablation zone and achieve higher temperature in ablation zone than 2450 MHz cooled-shaft antenna in ex vivo porcine livers.

Objective To access the long-term efficacy and safety of immunosuppression on the progression of IgA nephropathy (IgAN) by Meta analysis.Methods Databases EMBASE,Pubmed,Elsevier Science Direct,Scopus,Web of Science,Google Scholar,Cochrane Library,China National Knowledge Infrastructure,WanFang and VIP Data were retrieved to collect the randomized controlled trials (RCTs) at least 3 years follow-up on immunosuppression for IgAN published before May 2014.The literatures were screened independently by two reviewers according to the inclusion and exclusion criteria,and the methodological quality was assessed.Statistic software Stata 12.0 was used to conduct analysis.Results Nine articles were included in this study with a total of 568 patients.Immurnosuppression could lowered the risk for the progression to ESRD (RR=0.32,95％CI:0.20-0.49,P ＜ 0.01).As far as the efficacy of immunosuppression,subgroup analysis indicated that three studies with more than 7 year follow-up (RR=0.28,95％CI:0.13-0.59,P ＜ 0.01) were similar with 7 studies followed by for less than 7 years (RR=0.34,95％ CI:0.19-0.59,P＜0.01); six adopted immunosuppressor monotherapy (RR=0.29,95％ CI:0.15-0.58,P＜ 0.01) were similar to two used corticosteroids plus other immunosuppression (RR=0.33,95％CI:0.18-0.59,P ＜ 0.01); There were no significant differences between four studies from Europe (RR=0.27,95％CI:0.14-0.53,P ＜ 0.01) and five from Asia (RR=0.35,95％ CI:0.19-0.65,P＜0.01).Immunosuppression was associated with an increased risk for adverse events (RR=2.33,95％ CI:1.33-4.09,P＜0.01).Conclusion Immunosuppression for IgAN may reduce long-term risk of progression to ESRD,but increase the risk of adverse events to some extent.

Objective To investigate the effects of the fibrin-derived peptide Bβ15-42 (FgBβ 15-42) on renal inflammation in acute kidney injury (AKI) induced by renal ischemia reperfusion (IR).Methods SD rats were randomly divided into sham group (the abdominal cavity were closed after separating the renal artery),IRI group (renal arteries of rats were occluded with microvascular clamps for 60 min),negative treated group (rats were injected with 3.6 mg/kg random peptide by tail vein) and FgBβ15-42 treated group (rats were injected with 3.6 mg/kg FgBβ15-42 by tail vein).Rats were sacrificed at 24 h or 48 h after reperfusion.Blood and kidney samples were collected and histological changes and renal function were examed.The mRNA and protein expressions of intercellular cell adhesion molecule-1 (ICAM-1) and interleukin-1β (IL-1β) were examined by immunohistochemistry,real-time PCR and Western blotting.Results Compared with sham group,Scr and BUN were obviously increased in IRI group (all P ＜ 0.05),pathologic changes of kidney were more serious (P ＜ 0.05).Compared with IRI group,in FgBβ15-42 treated group Scr and BUN were obviously decreased (all P ＜ 0.05),the injury of kidney tubulointerstitial was less serious (P ＜ 0.05).Compared with sham group,there was increased ICAM-1 and IL-1β in IRI group (all P ＜ 0.05),and they all peaked at 24 h.After treated with FgBβ15-42,the expression of ICAM-1,IL-1β were significantly decreased in kidneys compared to IRI group (all P ＜ 0.05).The above indexes had no significant differences between negative treated group and IRI group (all P ＞ 0.05).Conclusions FgBβ15-42 can protect kidneys against ischemia reperfusion injury in rats.The mechanism may be associated with down-regulated expressions of ICAM-1 and IL-1 β in the kidney.

Objective To investigate the correlation between developmental function and pathological behavior in children with autism. Methods A total of 154 children with autism were tested with Revised Chinese Version Psycho-Educational Profile (C-PEP) during 2011 to 2014. Results The scores of fine movement, hand-eye coordination, and oral language of developmental function were lower in the girls than in the boys (t>2.120, P<0.05). Among the children with autism aged 2-7 years, the developmental function was better in the older group than in the younger group (P<0.05);however, it was not better in the children aged 8-10 years and>10 years than in those aged 6-7 years. There was no difference in the scores of pathological behavior between the girls and the boys (P>0.05). Some pathological behaviors were milder in the older group than in the younger group (P<0.05). The scores ofP(pass) in developmental function were positively correlated with the scores ofA(absence) in pathological behavior (P<0.01), and negatively correlated with the scores ofS(severe) in pathological behavior (P<0.01). The scores ofF(fail) in developmental function were negatively correlated with the scores ofA(absence) in patho-logical behavior (P<0.01), and positively correlated with the scores ofS(severe) in pathological behavior (P<0.01). Conclusion Develop-mental function of children with autism is highly correlated with pathological behavior, and the rehabilitation and education of children with autism aged above 7 years should be concerned.

Objective To follow up the rehabilitation, education, and assistive devices utilization of school age children with cerebral palsy. Methods From 2012 to 2015, 80 children with cerebral palsy were called their parents with telephone and filled in the questionnaires. Results 69 children (85.25%) continued to receive rehabilitation, 11 children (13.75%) stopped rehabilitation. 42 children (56.25%) received education in ordinary schools, 15 children (18.75%) received education in special schools, 4 children (5.00%) were nursed in nursing institu-tion, 16 children (20.00%) stayed at home and did not receive any education. The main problem and needing at present were receiving reha-bilitation, receiving school education, relief the rehabilitation cost of more than one institution, etc. 61 children (76.25%) ever applied for as-sistive devices, 19 children (23.75%) did not. The feedback of application process in order were smoothly;applied, but didn't get;the assis-tive devices that received was inappropriate. 29 children (73.75%) needed assistive devices currently, 21 children (26.25%) did not. When asked the category of needed assistive devices at present, 19 parents (20%) answered that they did not know the category of assistive devices well or they did not know which kind of assistive devices they needed. Conclusion It is important to provide quality and quantity rehabilita-tion and education service, popularize the knowledge of assistive devices and their clinical application for cerebral palsy children. Assistive devices providing departments should do more communication with cerebral palsy children and their parents, in order to reduce the waste of resources, and increase the rational use of resources, and provide more benefits for children with disabilities.
