Objective To investigate the effect of informational support on disease uncertainty in liver cancer patients undergoing interventional therapy. Methods Sixty patients of liver cancer patients undergoing interventional therapy were randomly divided into the intervention group and the control group with 30 in each.The control group was treated with general treatment and care. The patients in the intervention group were given general treatment and care with a series of informational support interventions. Patients in the two groups were measured by uncertainty in illness scale (MUIS) at the day of admission,before operations and discharged from hospital. The measurement results were statistically analyzed. Results There was significant decrease about disease uncertainty scores both on the day before operation and the day before discharge in the intervention group compared to the day of admission. The decreasing score of uncertainty in illness in the intervention group was significantly greater than the control group on the day before operation and the day before discharge. Conclusions A series of informational support interventions could significantly reduce the diseases uncertainty in liver cancer patients undergoing interventional therapy.

OBJECTIVE To analyze the drug resistance of 141 clinical strains of Acinetobacter baumannii to 15 kinds of antimicrobial agents for the rational application of antimicrobial agents.METHODS All 141 strains of A.baumannii isolates were tested for minimal inhibitory concentration(MIC) to 15 kinds of antimicrobial agents included meropenem,imipenem,piperacillin,and so on using agar dilution method.RESULTS The lowest resistance rate of A.baumannii to the antimicrobial agents was to imipenem(22.7%),then was to meropenem and cefoperazone/sulbactam.The highest resistance rate was tetracycline(81.5%).The resistance rate to other antimicrobial agents was to about or more than 50%.CONCLUSIONS Most of A.baumannii isolates are susceptible to meropenem,imipenem,and cefoperazone/sulbactam and resistant to other antimicrobial agents,therefore,we should enhance to this kind of isolates detection.

OBJECTIVE To investigate the resistance and molecular epidemiology of Pseudomonas aeruginosa isolated from ICU. METHODS Susceptibility of P. aeruginosa isolates to 14 antimicrobial agents were tested by microScan WalkAway-40 system,and Molecular typing was analyzed by enterobacterial repetitive intergenic consensus(ERIC-PCR). RESULTS The lowest resistance rate of P. aeruginosa to the antimicrobial agents was to ceftazidime (27.3%),then to cefepime (45.5%). The highest resistance rate was to cefotaxime (100.0%) and the resistance rate to other antimicrobial agents was more than 60.0%. Patterns of ERIC-PCR were same in 5 strains of P. aeruginosa. CONCLUSIONS P. aeruginosa isolated from ICU is resistant to most of antimicrobial agents and clone spread is found in them. We should enhance detection and surveying of these isolates.

Objective To investigate the adhesion levels in uropathogenic Escherichia coli with various degree of drug resistance.Methods One hundred strains of Escherichia coli isolated from urine specimen were collected from patients admitted to 4 Grade A tertiary hospitals in Tianjin during March 2012 to October 2015.Escherichia coli were divided into drug sensitive group and drug resistant group by drug sensitivity tests with 50 strains in each group.The expressions of fimH,fimA,fimB genes of type I fimbriae and papA,papB,papC,papGII genes of P fimbriae were detected by polymerase chain reaction(PCR)and real-time fluorescence quantitative RCR (RT-PCR),respectively.Adhesion ability of type I fimbriae and P fimbriae were tested by yeast cell adhesion test and erythrocyte agglutination test.Chi square test and t(Z) test were used to analyze the data.Results The positive rate of papGII in drug resistant group (42.0%) was significantly higher than that in the drug sensitive group (16.0%)(χ2 =8.208,P <0.05),while there were no significant differences in the positive rates of fimH,fimA,fimB,papA,papB and papC genes between two groups(all P >0.05).The expression levels of fimH,fimB and papC genes in the sensitive group were higher than those in the resistant group(Z =3.427,t =5.182 and 8.120,all P <0.05).The adhesion ability of strains carrying type I fimbriae in sensitive group was stronger than that of resistant group (χ2 =5.769,P <0.05).Conclusions The decline in adhesion ability of type I fimbriae in drug resistant E.coli strains is possibly associated with the adaptive cost of bacteria,the transcription and deficiency of other genes encoded by fim and pap gene cluster will also affect the adhesion function of type I pili and type P pili.

Objective To investigate the effect of Doula delivery ball apparatus combined with correct occipitoposterior.Methods Four hundred primiparas whose dilatation of cervix of 3 cm and position of foetus was occipitopostenor position, were randomly divided into observation group and control group according their wishes, and each group of 200 cases.Doula delivery ball was used for the observation group,while the free body position, the traditional delivery mode was the control group.The vaginal delivery rate, degree of pain, postpartum 2 h bleeding volume and neonatal asphyxia rate were compared between the two groups.Results The degree of pain Ⅲ degree was 4.0％ (8/200) ,lower than the control group(50.0％ (100/200), x2 =11.55,P＜0.01).The vaginal delivery rate in observation group was 84.5％ (169/200), higher than that in control group (60.5％ (121/200);x2 =28.905,P=0.001).Postpartum 2H bleeding was (156.3±53.2) ml, lower than the control group((268.1±54.6) ml, t =20.70, P＜0.01).The Postpartum bleeding rate was 0.5％ (1/200), lower than that in control group (4.0％ (8/200) ,P =0.018).Conclusion Doula delivery ball is applied to the first active stage of labor can effectively relieve pain, promote the safety of natural childbirth.

Aurora-B as an important kinase to adjust the cell normal mitosis is a potent target for cancer treatment. Aurora-B is overexpressed in a broad range of tumor and tumor cells are more sensitive while Aurora-B is inhibited. Due to the key role of the Aurora-B in cell mitosis, the development of its inhibitors is becoming more and more important. Several small molecules inhibit with a similar efficacy both Aurora-A and Aurora-B, however, in most cases the effects resemble Aurora-B disruption by genetic methods, indicating that Aurora-B represents an effective therapeutic target. There were several Aurora-B kinase inhibitors which had entered the clinics and displayed good antitumor activity. In this review, we will outline the functions of Aurora kinase B in normal cell division and in malignancy. We will focus on recent preclinical and clinical studies that have explored the mechanism of action and clinical effect of Aurora-B inhibitors in cancer treatment.

Objective To study the killing effects of fractional proteins from Microtus fortis (Mf) serum on schistosomula of Schistosoma japonicum. Methods Mf serum proteins were separated into albumin and globulin by means of salt out of ammonium sulfamate. The globulin was then separated into 4 big and 12 small fractional proteins through Sephacryl S-300 column chromatography and electrophoresis elution. The killing effects were observed in vitro in cultivation in which the purified fractional proteins and schistosomula of S. japonicum were incubated together for 48 h. Results The mortality rate of schistosomula acted by Mf globulin was 59.2% and when added with complements was 68.4%. The killing effects of the 2nd and 3rd big fractional proteins were the same as that of Mf globulin. Three small fractional proteins (3.2, 3.3, 3.4) showed the higher killing effects which made the mortality rate of schistosomula 45.1%, 57.6% and 67.2%, respectively. The fractional protein of 100-135 kDa also showed the same killing effect as that of Mf globulin. Globulin from BALB/c mice sera had no significant effect on schistosomula. There was no significant difference in the mortality rate of schistosomula acted by both albumins. Conclusions Mf globulin has significant killing effects on schistosomula of S.japonicum in vitro and 100-135 kDa fractional protein may be an important effective molecule.

Objective To investigate antiproliferative activity of endostatin(ES), the combining effect of Endostar and radiation on VEGF and apoptosis of the A549 human lung adenoearcinoma cell line.Methods The cell of exponential phase of growth were divided into the control, radiation alone, ES alone,radiation after ES(ES→RT), ES after radiation(RT→ES), radiation and ES at equal paee (RT+ES), γ-ray radiation at a dose of 2 Gy, single fracination irradiation, YH-16 10 μg/ml in the cell culture bottle. The combining effect was quantified by the survival curve. ELISA was used to observe the VEGF of radiation with ES on A549 cell lines. Apoptosis was observed by Hoeehst staining. Results There showed that both of ES and combining treatment had the function of antiproliferative. But the union treatment's function was more obvious (P＜0.05). The expression of VEGF in ES and the combining treatment group was more lower than others (P＜0.05). On apoptosis, the rate of apoptosis in ES, RT, combining treatment group was higher than others (P＜0.05). Conclusion On antiproliferative activity and rate of apoptosis, the combining of ES and radiation is better than to use them alone. To reduce VEGF of the A549 human lung adenocareinoraa cell line by ES could enhance radioresponse. There is no evidences to show that the expression of VEGF is concerned with the different choronological order of radiation and ES.
