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 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.

The aim of the current study was to investigate the spectra in the different organs of the rats which died of massive hemorrhage; to explore their spectral changes 15 days postmortem and the best mathematical model with different band absorption ratio changes to postmortem interval(PMD; and to compare the spectral changes of different temperature.Thirty male Sprague-Dawley rats were sacrificed by cutting abdominal aorta,and the cadavers were divided equally and kept at 4 ℃,20℃ and 30℃ in the control chamber.From the same rat,seven different organs were sampled at intervals of 1-15 days postmortem,and then measured by Fourier transfom infrared (FTIR)spectrometer.Six mathematical model functions were explored.The absorbance of bands and band absorbance ratios of absorption peak in each organ showed a time-dependent increase or decrease,most band absorbance ratios remaining stable for 7-15 days postmortem.Cubic model functions of the various bands absorbance ratios against PMI showed a stronger related coefficient.The absorbance bands with obvious changes at 20 ℃ showed stabilized tendencies at 4 ℃ and significant changes at 30 ℃ within 15 days postmortem.In addition,FTIR spectroscopy revealed a time-dependent metabolic process,with potential of being used to estimate PMI during 7 days postmortem,which merits further investigation.

Objective To investigate the renoprotective effect of transforming growth factor beta activator kinase 1 (TAK1) inhibitor 5Z-7-oxozeaenol (OZ) in diabetic db/db mice and the mechanism.Methods Twenty-four male db/db mice were randomly divided into two groups:db/db mice (db/db,n=12) and db/db mice with 5Z-7-oxozeaenol treatment (db/db+OZ,n=12).Another group of wild type mice (n=12) was held as the control group.OZ 2 mg/kg was administrated by intraperitoneal injection every other day.At week 8 and 12 after 5Z-7-oxozeaenol treatment,blood glucose (BG),body weight (BW),kidney weight (KW) and urinary albumin excretion rate (UAER) were evaluated.Kidney pathological lesions were detected by light and electron microscopy.NF-κB p65,monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-ot (TNF-o) were detected by immunohistochemistry.Western blotting was used to detect p-TAK1,TAB1,p-p38MAPK and IL-1β expression,while ICAM-1 and MCP-1 mRNA levels were evaluated by real-time PCR.Results Compared with control group,the levels of BG,BW,KW and UAER were higher (P ＜ 0.01) in db/db mice group,while BW,KW and UAER levels were significantly decreased in db/db + OZ group compared with that in db/db mice group (P ＜ 0.05).In week 8 and 12 db/db mice,glomerular volume and extracellular matrix were increased,while pathological lesions in kidney tissue were positively improved by TAK1 inhibitor.Immunohistochemistry showed that NF-κB p65,MCP-1 and TNF-α expression levels were apparently increased in db/db mice group compared with that in control group (P ＜ 0.05) and were significantly inhibited by TAK1 inhibitor (P ＜ 0.05).Western blotting showed that p-TAK1,TAB1,p-p38MAPK and IL-1β expression levels were higher in db/db mice group than that in control group (P ＜ 0.05) and lower in db/db+ OZ group than that in db/db mice group (P ＜ 0.05).Moreover,real-time PCR showed that the expressions of ICAM-1 and MCP-1 mRNA were higher in db/db mice group than that in control group and lower in db/db+OZ group than that in db/db mice group (P ＜0.05).Conclusions TAK1 Inhibitor can down-regulate MAPK and NF-κB pathway to restrain the reaction of inflammation and alleviate kidney injury in diabetic db/db mice.

Objective To investigate the role of transforming growth factor-β activated kinase-1 (TAK1) signaling pathway in the activation of bone marrow derived macrophages (BMDM) induced by high glucose.Methods Purity of mouse BMDM was detected by flow cytometry.The mice macrophages cultured in vitro were stimulated by high glucose and treated with TAK1 specific inhibitor 5Z-7-oxozeaenol.Cells were divided into normal control group (RPMI 1640),osmolality control group (25 mmol/L mannitol),high glucose group (33 mmol/L D-glucose) and inhibitor group (33 mmol/L D-glucose+300 nmol/L 5Z-7-oxozeaenol).Immunocytochemistry and flow cytometry were used to detect macrophage subtype.The expression of monocyte chemotactic protein-1 (MCP-1) and tumor necrosis Factor-α (TNF-α) mRNA were determined by real time PCR.Expressions of p-TAK1,TAK1 binding protein (TAB1),p-JNK,p-p38 MAPK and NF-κB p65 proteins were analyzed by Western blotting.Results The purity of BMDM was about 99.36％.Compared with normal control group,high glucose group had increased percentage of M1 macrophages,increased expression of MCP-1 and TNF-α mRNA (all P ＜ 0.05).Moreover,p-TAK1,TAB1,p-JNK,p-p38 MAPK and NF-κB p65 proteins expression also increased significantly in high glucose group (all P ＜ 0.05).After treatment with inhibitor 5Z-7-oxozeaenol,the effects induced by high glucose were inhibited (P ＜ 0.05).Conclusions High glucose can induce M1 macrophage activation and expression of inflammatory cytokine of BMDM,which can be inhibited 5Z-7-oxozeaenol through inhibiting TAK1/MAPK and TAK1/NF-κB pathway.

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.
