Objective To investigate the clinical value of serum soluble intercellular adhesion molecule-1 (sICAM-1 )in patients with primary biliary cirrhosis (PBC)and autoimmune hepatitis (AIH).Methods Sixty-one PBC patients and 59 AIH patients,who were hos-pitalized or visited the outpatient department from June 2012 to September 2013,as well as 50 healthy controls,were included in the study. The PBC patients included 29 incipient cases,21 cases in remission,and 11 recurrent cases;the AIH patients included 26 incipient cases, 20 cases in remission,and 13 recurrent cases.Serum sICAM-1 level was measured by double-antibody sandwich enzyme-linked immu-nosorbent assay,and serum levels of alanine aminotransferase (ALT)and total bilirubin (TBil)were determined by biochemical enzyme as-say.Comparison between groups was made by analysis of variance;Pearson correlation analysis was performed.Results Among PBC pa-tients,the incipient group and recurrent group had significantly higher serum sICAM-1 levels than the remission group and control group (P=0.000 for all);there was no significant difference in serum sICAM-1 level between the incipient group and recurrent group (P=0.484);the remission group had a significantly higher serum sICAM-1 level than the control group (P=0.000).Among AIH patients, the incipient group and recurrent group had significantly higher serum sICAM-1 levels than the remission group and control group (P=0.000 for all);there was no significant difference in serum sICAM-1 level between the incipient group and recurrent group (P=0.802);no significant difference in serum sICAM-1 level was seen between the remission group and control group (P=0.281).For patients with PBC and AIH,serum sICAM-1 level was positively correlated with serum levels of ALT (r=0.664,P=0.000;r=0.784,P=0.000) and TBil (r=0.715,P=0.000;r=0.580,P=0.000).Conclusion Serum sICAM-1 may be involved in the immunologic injury in PBC and AIH.In patients with PBC and AIH,the elevation of serum sICAM-1 level is closely correlated with the severity of liver damage. Clinical monitoring of serum sICAM-1 level may play an important role in severity assessment,prognostic evaluation,and therapy guidance among patients with autoimmune liver diseases.

Objective To investigate health care professionals′attitude of patient involvement in patient safety and analyze its influencing factors. Methods A convenience sample of 946 health care professionals recruited from twelve hospitals in Shanghai was employed for a cross-sectional survey. Results The general attitudes of patient involvement in patient safety scored 3.86 ±0.56, the perception of the content of patient involvement scored 3.97±0.54, the average score of caring involvement (4.12±0.59) was larger than the average score of decisive involvement (3.88±0.58), the average score of complaining involvement was the least (3.39±0.81), the difference had statistical significance (F=583.797, P<0.01). The regression analysis showed that identity, professional title, hospital grade influenced health care professionals′general attitude of patient involvement in patient safety and that identity, hospital grade influenced health care professionals′attitude of the content of patient involvement. Conclusions In health care professionals′opinion, patient involvement in patient safety has both advantages and disadvantages. They preferred to caring involvement, followed by decisive involvement, then complaining involvement. So, hospital managers should view patient involvement in patient safety discriminately and construct rational involvement model ofpatients willing, medical support, promote interaction and harmony build.

OBJECTIVETo study the effect of aqueous extract of Taxus chinensis var. mairei (AETC) combined Erlotnib on the growth of A549 xenograft in nude mice and its mechanism.

METHODSThe xenograft model in nude mice was established by inoculating A549 cells subcutaneously. BALB/c nude mice bearing A549 xenograft were randomly divided into six groups, i.e., the low dose Erlotinib group (A) , the standard dose Erlotnib group (B) , the low dose Erlotinib combined AETC group (C), the standard dose Erlotnib combined AETC group (D), the AETC group (E), the control group (F), 12 in each group. Different medication was performed for 7 successive weeks after 24 h. One mL blood was withdrawn and tumor tissues taken. The tumor inhibition rate was calculated. The combined effect was analyzed by Jin's Formula [Q = Ea + b/(Ea + Eb-Ea x Eb) ]. mRNA and protein expression levels of epidermal growth factor receptor (EGFR), cyclooxygenase-2 (COX-2), and B cell lymphoma-2 (Bcl-2) in xenografts were detected using real-time RT-PCR and ELISA.

RESULTSCompared with Group F, the xenograft weight was obviously lowered in Group B-E (P < 0.05, P < 0.01). The q value was 0.92 in Group C and 0.96 in Group D, which was obtained by simple adding of the two drugs. Compared with Group F, EG- FR mRNA expression in Group D and E, COX-2 mRNA expression in Group A-E; Bcl-2 mRNA expression in Group B-D; COX-2 protein expression in Group B-E; Bcl-2 protein expression in Group C and D were obviously lowered with statistical difference (P < 0.05, P < 0.01).

CONCLUSIONSAETC combined low dose and standard dose Erlotinib had synergistic effect on tumor inhibition. Its mechanism might be associated with down-regulating mRNA and protein expression levels of COX-2 and Bcl-2.

Objective To assess the value and clinical applicability of non-treponemal antigen serologic test and Treponema pallidum antigen serologic test in the diagnosis of congenital syphilis. Methods Totally,7800 newborns were collected from the out-patient and in-patient department. Toluidine red unheated serum test (TRUST) was conducted to quantitatively detect non-treponemal antibodies and Treponema pallidum particle agglutination assay (TPPA) to qualitatively detect specific treponemal antibodies in these subjects. The results of first serology test for syphilis were assessed for neonates with confirmed congenital syphilis. The sensitivity and specificity in the diagnosis of congenital syphilis were compared between TPPA and TRUST.Results Of the 7800 newborns undergoing syphilis serology testa, 60 were positive for TPPA and TRUST,including 15 cases of congenital syphilis, 47 were positive for TPPA but negative for TRUST, including 5 cases of congenital syphilis. The sensitivity and specificity were 75% (5/20) and 99.41% (7734/7780) respectively for TRUST in the diagnosis of congenital syphilis, 100% (20/20) and 98.88% (7693/7780) respectively for TPPA. Conclusion TPPA seems more applicable than TRUST to the screening for congenital syphilis.

Objective To explore the method and effect of checklist tool implemented in the safety management of clinical blood transfusion in intensive care unit. Methods A checklist was specially designed according to the technical standard and check system of clinical blood transfusion. 379 patients prescribed a blood transfusion enrolled in ICU from January to May 2013 were conducted as the control group before the checklist was designed. After the application of checklist during the blood transfusion process, 846 patients prescribed a blood transfusion enrolled in ICU from June to December 2013 were conducted as the experimental group. The incidence of blood transfusion safety related adverse events between the two groups was compared.
