Objective To determine the inhibitive effect of interferon-a on hepatic metastasis of colon cancer. Methods Metastatic model of human colon cancer was established by orthotopic implantation of histologically intact human tumor tissue into the colon wall of nude mice.The mice were randomly divided into 4 groups:(1)Control group(receiving saline solution only);(2)5-FU treatment group;(3) IFN-?-2b treatment group;and(4)5-FU combined with IFN-?-2b treatment group(combined group). 5-FU and IFN-?-2b were given via peritoneum injection 1 time/2 days for eight weeks.The mice were killed at nine weeks.The tumors were weighed,the microvessel density(MVD) was detected,and the liver was examined histologically in order to discover the micrometastasis. Results In control group, 5-FU group,IFN-2b group and combined group,the tumor weight was(1.53?0.78)g,(0.87?0.59)g,(0.81?0.43)g and ( 0.23?0.09)g, respectively;the tumor inhibition rate was 0,43.1%,47.1% and 84.9%, respectively;the hepatic metastasis rate was 85.7%,78.6%,21.4% and 0 respectively.MVD in IFN-? group and combined group was significant lower than that in control group and 5-FU group. Conclusions IFN-? can inhibit the growth and hepatic metastasis of orthotopic implanted human colon cancer by inhibiting the tumor angiogenesis.It may be more effective when INF-? combined with cyotoxic agents.

Objectives To determine the prevalence of Staphylococcus aureus (S. Aureus) colonization and S. aureus-derived exotoxins in lesions of childhood atopic dermatitis (AD) and evaluate the role of S.aureus-derived exotoxins in the pathogenesis of childhood AD. Methods Specimens were taken from the skin lesions of 148 patients, non-lesional skin of 30 patients, and the skin of 250 controls for bacterial cultures. S. aureus-derived exotoxins were detected by reverse passive latex agglutination. Total IgE levels were determined with immunoradiometric assay. Results The prevalence of S. aureus colonization was significantly increased in both the lesional and non-lesional skin of patients with AD in comparison with the controls (P 0.05). However, patients with increased total IgE levels showed significantly high SCORAD indices (P

The content of SO2 in Paeoniae Radix Alba (RPA) was determined by the method documented in Chinese Pharmacopoeia (CP) 2010 edition to validate the repeatability of the method for evaluating RPA, and the contents of paeoniflorin sulfonate in both the residual material and distilled solution of RPA were determined by HPLC to study the transformation of paeoniflorin sulfonate to SO2 by HCl. It was found that the repeatability of the method in CP for evaluating RPA is unacceptable, and paeoniflorin sulfonate was detectable in both the residual material and distilled solution of RPA even at "the end point" of SO2 determination, merely about 50% of paeoniflorin sulfonate was transformed to SO2 by HCl, indicating that the current SO2 determination method in CP is not able to accurately quantify SO2 in RPA. It is recommended that more special method for determining SO2 content in RPA should be developed regarding the chemical characteristics of sulfur-fumigated RPA.

Objective To investigate the diagnostic value of non-invasive cardiac output parameters:cardiac index (CI) and minute distance (MD), in premature infants with patent ductus arteriosus (PDA) and determine the cut-off value. Methods Clinical data of 98 premature infants admitted to the neonatal intensive care unit from January 2015 to June 2015 were collected. These premature infants were divided into the treated PDA group (n=30),the untreated PDA group (n=28) and the normal premature group (n=40) based on the results of echocardiogram in the first three days after birth and the use of drugs. Non-invasive cardiac output parameters were measured in the first three days after birth. The data were analyzed by t test, analysis of variance and SNK-q test. The diagnostic value of CI and MD for PDA was analyzed by the receiver operating characteristic curve. Results By preliminary analysis of the ROC curve,CI and MD were the most representative parameters for the diagnosis of PDA which need to be treated clinically, we thus chose CI and MD in this study. The aortic and pulmonary arterial CI and MD in the treated PDA group were significantly higher than in the untreated PDA group and the normal premature group (all P<0.05). There were no significant differences between the untreated PDA group and the normal premature group in the aortic and pulmonary arterial CI and MD (all P>0.05). The cut-off value of the aortic CI and MD was 2.95 L/(min·m2) and 21.50 m/min, respectively, while that of the pulmonary arterial CI and MD was 4.55 L/(min·m2) and 26.50 m/min, respectively. The sensitivity and specificity of the combined aortic CI and MD for the treated PDA group were 0.90 and 0.82, and those of combined pulmonary arterial CI and MD were 0.87 and 0.82;and those of combined aortic and pulmonary arterial CI and MD were 0.80 and 0.88, respectively. Conclusions The non-invasive cardiac output parameters CI and MD have good diagnostic value for the PDA needing clinical treatment, and the combined use of the two parameters can improve specificity, and help formulate the early treatment strategy for premature infants with PDA. When aortic CI was ≥ 2.95 L/(min·m2) and MD was ≥ 21.50 m/min, a preliminary diagnosis of the PDA needing clinical treatment, can be made, and simultaneously when the pulmonary arterial CI was ≥4.55 L/(min·m2) and MD was≥26.50 m/min, the arterial duct should be closed timely.

Objective To explore the relationship between childhood abuse experience,parent and peer attachment and depression in adolescents.Methods A total of 736 junior students from the 7th,8th and 9th grades of 2 public schools in Xinxiang City and Jiyuan City Henan province completed the questionnaires.Childhood Trauma Questionnaire(CTQ),Inventory of Parent and Peer Attachment(IPPA) and Depression Self-Rating Scale for Children(DSRSC) were employed the childhood abuse experience,parent attachment quality and depressive mood in adolescents,respectively.The hierarchical regression analysis was used to examine the relationship between parent and peer attachment,child abused experience and depression.Results Male participants reported high score of childhood abused than female participants(33.29±7.89 and 31.05±6.01,t=4.343,P=0.000).There were no significantly gender difference in mother attachment(male:59.89±15.86,female:61.45±16.48,t=-1.303,P=0.193),father attachment(male:59.32±17.17,female:60.28±16.95,t=-0.764,P=0.445) and depression(male:7.68±5.27,female:7.31±4.21,t=1.057,P=0.291).Childhood abuse had a positive correlation with adolescent depression(r=0.408,P=0.000),which negatively correlated with mother and father attachment(r=-0.544,-0.417,respectively,Pa=0.000).There was a positive correlation between mother attachment and father attachment(r=0.604,P=0.000),and both of them had negative correlation with depressive disorder(both r=-0.426,Pa=0.000).Mother and father attachment were the partial mediation of the relationship between childhood abuse and adolescent depression.Conclusions Male adolescents suffered more maltreatment than female adolescents.There are no gender difference in parent attachment and depression.Parent attachment plays the partial mediator role in childhood abuse and adolescent depression.Results reveal the importance of assessment and consideration of parent attachment in the intervention of depression in abused adolescents.

Objective To study microbial flora on skin lesions and their antim icrobial susceptibilities and to conduct a topical treatment trial in atopic der matitis (AD). Methods Seventy one patients with AD were diagnosed according to the criteria of Hanifin-Rajka′s in departments of dermatology in China-Japan Friendship Hospital and Beijing Children Hospital during November,2001 to March, 2002. Bacteria and fungi were examined by culture and microscopy. Among 71 case s, 66 were divided into two groups randomly with one group receiving 1%econazol e+0.1%triamcinolone acetonide cream topically twice daily for 4 weeks, and the control group receiving 0.1%hydrocortisone butyrate ointment. Severity of AD w as measured by SCORAD index. Results It was shown that AD mainly affected infant s and children with a prevalence of 73.24%in patients less than 12 years old. T he rates of bacterial and fungal colonization were 53.51%, 1.41%, respectively on skin lesions. S.aureus was detected in 35.21%of patients with AD. Antimicro bial susceptibility test indicated that S.aureus was sensitive to rifampin, vanc omycin, amikacin, ciprofloxacin, cefazolin, cefuroxime, etc. It was found that 1 %econazole+0.1%triamcinolone acetonide cream had significantly more advantage over hydrocortisone butyrate ointment in the therapeutical effects (P
