The main objective of this research is to investigate the effects of astragaloside IV, calycosin separately glucoside, formononetin on oxidative stress in Chang Liver cells induced by H2O2. In the experiments, Chang Liver cells (a kind of normal human hepatocytes) were used as the research object, bifendate which has a clear hepatoprotective effect was used as the positive control drug, then the oxidative damage model of Chang Liver cells were established by H2O2. Cells were divided into six groups: blank control group, oxidative stress group, astragaloside IV group, calycosin separately glucoside group, formononetin group and positive control group. Then endogenous antioxidant system related indexes were detected by micro plate and colorimetric method; intracellular reactive oxygen species (ROS) were detected by DCFH-DA fluorescent probe; and the expressions of CYP2E1 were evaluated by liver microsomes, mRNA, and protein, respectively with spectrophotometry, Real-time PCR method, and Western blot technique. Results showed that H2O2 decreased antioxidant activity, and increased ROS level and expression of CYP2E1. The above oxidative stress status had been changed with protections of the three components of Astragalus membranaceus (compared with oxidative stress group, P < 0.05, P < 0.01), which taken as a whole had equivalent effects as the drug of positive control group( bifendate). Taken together, three Astragalus membranaceus ingredients all had significant or extremely significant inhibiting effects on oxidative damaged Chang Liver cells which were induced by H2O2, and the oxidative damage of Chang Liver cells had been relieved.

Objective To study diagnosis and treatment of rhabdomyosarcoma (RMS) in children.Method The clinical data of 43 children with RMS was retrospectively reviewed from Nov 2004 to May 2012.Their long-term survival was followed up.Forty-three children with RMS(male 26,female 17) in Beijing Tongren Hospital were enrolled.Their median age on diagnosis was 6 years old.We confirmed the diagnosis according to pathological diagnosis.Comprehensive treatment included chemotherapy,surgery and implantation of radioactive seeds,and so on.Statistical analysis was used on clinical data and treatment efficacy.Result The median follow up time of 43 cases with RMS in children was 31 mouths until May 2012.Four cases abandoned,39 cases were followed up.The cases of complete remission were 27(69％),and the cases of partly remission were 7 (18％),and the cases of dead were 5 due to cerebral metastasis.Overall survival rate was 87％ (34/39).Eight cases were treated with 125Ⅰ particles implants into its location,7 cases responded,1 case was invalid.Conclusion Although anatomic structure of RMS of head and neck was very complex,and the prognosis of it with metastatic disease was inferior,the muttidisciplinary treatment can still improve the clinical remission rate.In particular,high risk RMS with 125Ⅰ particles implants and large dose chemotherapy would be beneficial.

Objective To investigate the clinical values of Gemstone Spectral Imaging coronary angiography with analysis of the relationship between plaque character and angina pectoris types.Methods Two hundred cases of hospitalized patients were collected from January 2015 to December 2016 in the Department of Cardiovascular Disease,Chenzhou City First People's Hospital,who were diagnosed as coronary heart disease.According to the clinical data,stable angina pectoris (SA) and unstable angina pectoris (UA),coronary CT scan was performed for each patient to evaluate the relationship between the nature of atherosclerotic plaques and the classification of angina pectoris.SPSS 19.0 software was used for statistical analysis.Results By analyzing the correlation between SA and UA,SA calcification plaque was accounted for 63.2％,soft plaque 17.4％,mixed plaque 19.4％;UA calcification plaque was accounted for 37.5％;Soft plaque was accounted for 42.3％;and mixed plate was accounted for 20.2％.The difference was statistically significant (P ＜ 0.05).In the SA group,all of the stenotic lesions were mainly calcified plaques.There was no significant difference in the degree of severe stenosis between the different plaques in the SA group (P ＞ 0.05).In UA group,soft plaques were the main lesion of mild and moderate stenosis of coronary artery,and calcified plaques were the main stenosis in severe stenosis.There were significant differences in the degree of coronary artery stenosis between different plaques in UA group (P ＜ O.05).Conclusions The 128-slice spiral CT can accurately evaluated the relationship between the nature of coronary plaque and the type of angina pectoris,which is of great value in the early warning and angina pectoris classification of high-risk patients with coronary heart disease.

Objective:To explore the impact of clinical pharmacists involved in the treatment team on the reasonable drug use rate in medical orders. Methods:Totally 782 medical records including hypertension and 1-3 kinds of hypertension associated diseases in our hospital from January 2011 to December 2011 were used as the pre-intervention group, and 1 061 ones with the same conditions from September 2012 to August 2013 were used as the post-intervention group. The patients of the two groups were divided into 8 dis-ease subgroups, clinical pharmacists performed timely intervention on the medical orders in the post-intervention group, and the rational drug use rate between the two groups was compared. Results:In hypertension, hypertension associated coronary heart disease, hyper-tension with heart failure and hypertension with diabetes subgroups,the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 01), in hypertension with coronary heart disease and heart failure, hypertension associ-ated coronary heart disease and diabetes, hypertension with heart failure and diabetes subgroup, the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 05), while in hypertension with coronary heart disease, heart failure and diabetes subgroups, the difference was not statistically significant(P>0. 05). After the medical records in the 8 sub-groups were aggregated, the difference in the rational drug use proportion before and after the intervention was statistically significant( P<0. 01). Conclusion:Clinical pharmacists should involve in the clinical treatment to intervene irrational drug use,which can signifi-cantly improve the medical record rationality, avoid the health risks as much as possible and ensure the medication safety and treatment effectiveness for patients.

Objective To evaluate the perinatal outcome of three types of monochorionic diamniotic (MCDA) twins with selective intrauterine growth restriction (sIUGR).Methods From January 2005 to June 2012,clinical data of 42 pairs of MCDA twins (84 fetuses) with sIUGR and 71 pairs of normal MCDA twins (142 fetuses) in the same period were analyzed retrospectively in the First Affiliated Hospital of Sun Yat-Sen University.Fetuses with sIUGR were classified into three groups based on umbilical artery Doppler flow.There were 25 cases of type Ⅰ,11 cases of type Ⅱ and 6 cases of type Ⅲ.The perinatal outcome was compared between sIUGR and normal MCDA twins,and among the three types of sIUGR as well.Perinatal outcomes included gestational age at delivery,rate of intrauterine fetal death (IUFD),birth weight,intertwin discordance of birth weight,neonatal death and survival rate at 6 months.Results (1) The gestational age of sIUGR at delivery was significantly earlier than the control group [(34 ± 3),(36 ±2) weeks,respectively],and the rate of IUFD of both fetuses of sIUGR was significantly higher (4.8％,0,respectively).In the sIUGR group,the average birth weight of large or small twins[(2130 ±.350),(1520 ±400) g,respectively] was smaller than those in the control group [(2470 ± 500),(2340 ± 460) g,respectively].The difference was statistically significant (P ＜ 0.05,P ＜ 0.01,respectively).The intertwin discordance of birth weight in sIUGR group was significantly larger (27.6％) than the control group(4.0％,P＜0.01).(2) The gestational age at delivery in type Ⅱ and type Ⅲ [(34 ±5),(34 ±2) weeks,respectively] was significantly earlier than the control group (P ＜ 0.05).The rate of IUFD of both fetuses in type Ⅱ (18％) was significantly higher than in type Ⅰ (0) and the control group (0,P ＜ 0.05).In sIUGR group,the average birth weight of small twins in type Ⅰ,type Ⅱ and type Ⅲ was (1640 ±430),(1330 ±310) and (1500 ±380) g respectively,all of which were significantly smaller than that in the control group (P ＜ 0.05).The average birth weight of small twins in type Ⅱ was smaller than in type Ⅰ and the difference was statistically significant (P ＜ 0.05).In sIUGR group,the intertwin discordance of birth weight in type Ⅰ,type Ⅱ and type Ⅱ was 24.1％,34.6％,31.3％ respectively,all of which were significantly larger than that in the control group(4.0％,P ＜ 0.05).There were no statistically significant differences of the intertwin discordance of birth weight among the three types of sIUGR(P ＞0.05).Survival rate at 6 months in type Ⅱ (64％) was significantly lower than in type Ⅰ (92％) and the control group (91.5％,P＜0.01).Conclusions The perinatal outcome of MCDA twins with sIUGR is poor.The outcome is different among the three types of sIUGR,and type Ⅰ is the worst.Type Ⅱ is associated with a high risk of intrauterine fetal demise.It is important to monitor the intrauterine situation closely.

Objective To test the reliability and validity of CRIES-13(Chinese edition). The Children Revised Impact of Event Scale (CRIES-13) was recommened for diagnosing PTSD of children. Methods In the last third of the September 2008,according to the suffering condition,600 students were choosed who were fit for the research standard as subjects in two middle schools randomly. The viability of CRIES-13 was weighted by testretest reliability,Cronbach' s alpha,Split half reliability. The validity of CRIES-13 was analysed by content validity ,criterion validity,construction validity. Results In the test-retest reliability of CRIES-13, the Spearman correlation coefficient of total,intrusion factor,avoid factor,high warkening factor were 0.79, 0.75, 0.71, 0.75. Significant correlation were found among these scores. The Cronbach' s alpha of population was 0. 81. The Cronbach' s alpha of three factors was 0. 79 ( intrusion factor) , 0. 71 ( avoid factor), 0. 65 ( high awarkening factor). CRIES-13's split-half reliability was 0. 85. In the content validity test,the Spearman rank correlation coefficient between total score and each item was 0. 83 (intrusion factor), 0. 75 (avoid factor), 0. 85 (high awarkening factor). The correlation between intrusion factor and avoid factor was 0.63. The correlation between avoid factor and high awarkening factor was 0.41. The correlation between intrusion factor and high awarkening factor was 0.41. In struction validity, variance orthogonal rotation factor analysis was adopted and got three general factors. Their cumulative contribution to total variance was 55.52%. In the criterion validity test,significant correlation was found between intrusion factor and SDQ emotional factor and depression scale total score. Significant correlation was found between high awakening factor and SDQ emotional factor and depression scale total score. Conclusion The reliability and validity of CRIES-13 was good. It could be used extensively.

Objective The Children's Revised Impact of Event Scale (CRIES-13) is used for Screening PTSD of children. The reliability and validity of CRIES-13 is good. To research the demarcation points of CRIES-13 (Chinese version) based on the reliability and validity analysis,and to improve the useful value of the scale.Methods In late September 2008, according affected condition, students were choosed who were fit for the research standard as subjects in two middle schools. First,general questionnaire (self-writing) and CRIES-13 were applied to the subjects. Second, according to K-SADS-PL, physician carried out diagnosis meeting and evaluation to 310 students who were classified by stratified rand sampling. Critical point of CRIES-13 was divided by K-SADSPL. The assessment value of it were sensitivity, specificity, veracity, PPV, NPV. The right choice of division was measured by ROC curve. Results When the critical score was higher than 30, the score of Se ( 0. 833 ), Sp(0. 836) and NPV (0.97) was in the high level. Conclusion When the critical score is higher than 30, the scale have a good discrimination for PTSD, non-PTSD and it can be used extensively.
