Objective To investigate the synergistic anticancer effect of ATO combined with Rad001 on human ovarian cancer cells in vitro and the underlying mechanisms. Methods SKOV3 cells were treated with Rad001, ATO and a combination of Rad001 and ATO, respectively. Cell relative luminescence units, viability, and combination index were tested. The apoptosis was quantified by Flow cytometry. Autophagy and apoptosis associated proteins were measured with immunoblotting. Results Significant decrease in live cell number were observed in cells treated with combination of Rad001 and ATO , compared with single compound treatment (P <0.05). Moreover, a higher rates of autophagy as well as apoptosis were observed in the combination treatment compared with single compound treatment (P < 0.05). Conclusions combination of Rad001 and ATO can result in synergistic cytotoxicity through activation of the excessive autophagy and apoptotic pathway.

Objective To investigate the distribution and antimicrobial resistance profile of the common pathogens isolated during the period from 2009 to 2015.Methods All the bacterial strains isolated from pediatric inpatients in Beijing Children's Hospital during the period from 2009 to 2015 were analyzed. Antimicrobial susceptibility was determined by disk diffusion method and Phoenix 100 Automated Microbiology System. Results were analyzed according to the guidelines of CLSI (2014) using WHONET 5.6 software.Results The total strains were 26630. The most common gram-positive isolates were Streptococcus pneumoniae,Staphylococcusaureusand coagulase-negative Staphylococcus (CNS), while the most frequently isolated gram-negative microorganisms were Klebsiella spp.,Pseudomonas aeruginosa and Escherichia coli. The prevalence of S. pneumoniae was up to 25.7 % (4101/15973) in all respiratory tract specimens. About 50.2 % of the S. pneumoniae isolates were not susceptible to penicillin. The prevalence of methicillin-resistant strains was 20.6 % in S. aureus (MRSA) and 87.8 % in coagulase negative Staphylococcus (MRCNS) on average. The prevalence of MRSA increased from 11.1 % in 2009 to 29.8 % in 2015. No S. pneumoniae or staphylococcal strains were found resistant to vancomycin or linezolid. The Enterococcus strains were still highly susceptible to vancomycin and linezolid. Overall 0.3 % of the Enterococcus faecium isolates were resistant to vancomycin. The extended-spectrum beta-lactamases (ESBLs) producing strains accounted for 71.4 % -78.1 % of E. coli and 65.1 % - 76.9 % of K. pneumoniae isolates. The carbapenem-resistant E. coli and K. pneumoniae were reported for the first time in 2010, but in 2014, the strains resistant to carbapenems had increased to more than 7 % in E. coli, and higher than 20 % in K. pneumoniae. In 2015, up to 27.7 % and 25.7 % of P. aeruginosa isolates were resistant to imipenem and meropenem, respectively, and 59.9 % of the A. baumannii isolates were resistant to imipenem and meropenem. Beta-lactamase was positive in 46.3 % of the H. influenzae isolates. Conclusions MRSA and the carbapenem-resistant strains of E. coli,K. pneumoniae and A. baumannii are still on the rise in pediatric inpatients, which poses a serious threat to clinical practice and implies the importance of strengthening infection control.

Objective To report a peliosis hepatic in child and review literature and discuss.Methods Case history was inquired.Physical,labtoratory,imagement and histopathology of liver biopsy(HE staining) were examed.Results A 4-year old girl appeared dermatitis with erythema and herpes at local skin where was bit by insect before onset.The girl appeared fever,cough,then abdominal pain,hepatomegaly,pleural effusion and ascites.Lab examination revealed slight elevation of aspartate transaminase,?-glutamyltranspeptidase and alkaline phosphatase.The liver B-mode ultrasonography and CT scan revealed hepatomegaly with density heterogeneity of the parenchyma.The liver biopsy revealed many small capsule filled with blood cells.Conclusions Clinical characteristics of the disease are fever,upper abdomen pain,janundice,ascites and hepatomegaly.The diagnosis shall be combined with the pathologic biopsy of liver.

Objective To investigate the learning curve of laparoscopy-assisted anorectoplasty in the treatment of high imperforate anus.Methods Sixty patients with high congenital anal atresia who were treated with laparoscopy-assisted anorectoplasty in the Capital Institute of Pediatrics from December 2008 to October 2015 by one experience surgeon were selected as observation group.Based on the criteria,the patients were divided into 4 groups(15 cases in each group) according to the sequence of the operation and every 15 cases served as a learning phase.The operating time,frequency of operation,complication rate,conversion rate to open surgery,blood loss,the rates of blood transfusion and hospital stay were compared among the 4 phases.Results The mean operation duration was (176.3 ±41.6) min,(128.8 ± 36.1) min,(127.3 ± 35.2) min,(124.0 ± 30.1) min in group A,B,C and D,respectively.The operation duration of 4 groups showed a declining trend.Group A has longer operation time than group B,C and D,the difference were statistically significant (P ＜ 0.05).In detail,the comparison of operation time between group A and group B was statistically significant (P ＜ 0.05).Furthermore,group A had significantly more median blood loss than group B,C and D,the differences were statistically significant [the 4 groups of data,respectively,group A:(17.5 ±6.5) mL,group B:(15.0±5.0) mL,group C:(14.5 ±5.5) mL,group D:(8.5 ±6.5) mL,P＜0.05].The mean capacity of blood loss was 12.7 mL.No significant difference was found in surgical complications,the rates of blood transfusion,total hospital stay,and postoperative hospital stay among the 4 groups(P ＞ 0.05).But the postoperative hospital stay decreased from 9.8 d (group A) to 7.4 d (group D).Conclusions For a well-trained surgeon in imperforate anus surgery.The learning curve of laparoscopy-assisted anorectoplasty in the treatment of high imperforate anus on about 15 cases helps to make a skillful surgeon.

Objective To investigate the expression of survivin and bcl-2 in human squamous cell carcinoma (SCC) lesions and cell line SCL-1. Methods Tissue samples from 60 patients with SCC and 10 normal human controls were immunohistochemically stained to detect the expressions of survivin and bcl-2.Western blot was used to measure the expressions of bcl-2 and survivin proteins in HaCaT human keratinocytes and SCL-1 human squamous cell carcinoma cells. Results In normal control tissues, there was no expressions of survivin or bcl-2, while in SCC, the expression rates of bcl-2 and survivin were 70% and 60%, respectively,and there was no statistical correlation between the expressions of bcl-2 and survivin (P >0.05). Neither the expression of survivin nor that of bcl-2 was correlated to patients' age, gender or lesional site (all P >0.05). A statistical correlation was observed between the pathological stage in patients and expression of bcl-2 as well as between lymph node metastasis and expression of survivin (both P < 0.05). Western blot analysis revealed a significant increase in the expression of survivin and bcl-2 in SCL-1 cells compared with HaCaT cells. Con-clusion In SCC, survivin and bcl-2 seem to play their roles via different anti-apoptotic pathways.

In this study, 120 patients with rheumatic heart disease undergoing valve replacement were randomly divided into the control group and the Qishen group, with 60 cases in each group. Before the operation, the control group was given routine heart and diuretic treatments and placebo of Qishen Yiqi dropping pills for seven days (0.5 g each time, three times a day); While the Qishen group was given Qishen Yiqi dropping pills for seven days (0.5 g each time after meal, three times a day) on the basis of the routine treatments. The right ventricular end-diastolic volume (RVEDV), end-systolic volume (RVESV), stroke volume (SV) and right ventricular ejection fraction (RVEF) were detected after the operation. The results showed that patients in the two groups showed significantly lower right ventricular end diastolic volume (RVEDV), right ventricular end systolic volume (RVESV) and stroke volume (SV) decreased than that before the operation, but with significantly higher Ejection fraction (RVEF) significantly than that before the operation. However, the Qishen group showed a significantly lower right heart function reduction than the control group, with the statistical significance in the differences (P < 0.05). This indicated that the pretreatment with Qishenyiqi Drop Pills showed a remarkable efficacy in the improvement of right ventricular function after valve replacement.
