Objective To discuss the effect of targeted information support on the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention and its instructive significance to nursing work.Methods We randomized 118 patients treated with percutaneous coronary intervention whose sense of uncertainty and anxiety were relative intensive into the test group and the control group with 59 cases in each group.We gave routine health instructions to the control group while targeted information support besides routine health instructions to the test group.We investigated the patients in two groups by Chinese version of uncertainty scale and State Anxiety Inventory at 4 time points,that is ,the first day in hospital,night before the operation,24 hours after the operation and 1 day before leaving hospital.Results The anxiety level and sense of uncertainty about illness decreased at the night before operation,24 hours after operation and 1 day after operation compared with the control group.The sense of uncertainty and anxiety level has statistical difference between whatever two adjacent time points except for anxiety level between the time points between the first day in hospital and before operation.Drop of sense of uncertainty at 24 hours after operation was significantly different between the two groups(P<0.01).Conclusion Supplying targeted information support could decrease the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention.

Objective:To investigate the effects of oxidation of titanium on bonding strength of titanium and porcelain. Methods: 24 specimens with a size of 28 mm ?3 mm?0.5 mm were cast from pure titanium and divided into 4 groups, 6 specimens each group. Group 2, 3 and 4 were degassed at 750, 800 and 900 ℃ respectively, group 1 not degassed as negative control, then a uniform thickness of 1mm of Noritake super porcelain Ti-22 was veneered on 8 mm?3 mm in the central portion of each specimen. The specimens were subjected to a three-point bending test on a load-test machine with a span of 20 mm, and the failure loads were recorded and analyzed statistically. The opposite side of specimens of each group were observed by thin-film X-ray diffraction. Results: The failure loads (N) of group 1, 2, 3 and 4 were 10.33, 9.98, 5.53, 3.37. The oxide of group 1 was Ti6O only, the oxide of the gropu 2, 3, and 4 were Ti6O and TiO2 and the amount of TiO2 increased significantly as the temperature iss increasing. Conclusion: The oxide adherence strength value for pure titanium decreased while the oxide temperature is increasing. The higher of the degassed temperature of the specimens, the more TiO2 can be found in the oxide film and the smaller the failure load is, which indicats that oxidation of titanium has a negative effect on the bonding strength of porcelain and titanium.

Objective To establish a biotin-streptavidin ELISA method to measure CTGF,and evaluate the clinical value of CTGF for the diagnosis of liver fibrosis in chronic hepatitis B (CHB) patients.Methods Biotinylated anti-CTGF polyclonal antibody and monoclonal antibodies were prepared for the establishment of this biotin-streptavidin ELISA method.Two hundreds and sixty-four CHB patients were subjected into non-or mild liver fibrosis group (S0-S1,108 cases) and severe liver fibrosis group (S2-S4,156 cases),according to the liver biopsy pathological diagnosis.The CTGF assay's diagnostic capacity for CHB was assessed by comparing the area under ROC (AUC) with that of a panel of hepatic fibrosis markers ( HA,PC Ⅲ,C Ⅳ,LN and APRI).Analysis of variance and rank sum test were performed to carry out comparisons between multiple groups.Student's t-test and Mann-Whitney U test were performed for the pairwise comparison between multiple samples.Spearman rank correlation test was performed to analyze the correlation between different hepatic fibrosis stages.Results The minimum detectable dose and detection rang of the ELISA was 0.2 μg/L and 0-64 μg/L respectively.The intra-assay and inter-assay CV at high and low level were 4.5％,9.8％ and 10.1％,12.8％ respectively.Serum CTGF concentrations in S0-S1 group and S2-S4 group were 6.7(3.1 - 10.1 ) μg/L and 16.1 ( 11.8 -27.2) μg/L,with a statistically significant difference (U =1 217,P ＜0.001 ).There was a significant correlation between the levels of serum CTGF and fibrosis stages ( r =0.689,P ＜ 0.001 ),AUC of CTGF was 0.841 (95％ CI:0.762 - 0.920) in distinguishing mild fibrosis from significant fibrosis.When the cut-off value of CTGF was 10.3 μg/L,the sensitivity and specification was 70.5％ and 82.4％ respectively.The sensitivity of parallel combination test of CTGF and APRI was 96.1％,which was higher than that of HA (75.6％),PC Ⅲ (70.5％ ),C Ⅳ(63.6％),LN(79.5％ ),APRI(86.3％ ).The specificity of the combination test was 65.5％,which was lower than of above liver fibrosis markers [HA ( 72.5％ ),PC Ⅲ ( 76.5％ ),C Ⅳ ( 78.4％ )].The specificity of serial combination test of CTGF and PC Ⅲ was 95.9％,which was higher than that of HA,PC Ⅲ,CⅣ,LN(64.7％ ),APRI(66.1％ ),however,the sensitivity of the combination test was 67.7％,which was lower than that of above HA,PC Ⅲ,and APRI.Conclusions The biotin-streptavidin ELISA method measuring serum CTGF has a high minimu detectable dose sensitivity,and specificity.Serum CTGF level is significantly correlated with fibrosis stage,and CTGF maybe a valuable marker for liver fibrosis assessment.The paralledl combination of CTGF and APRI could be used as screening for significant liver fibrosis markers.The serial combination of CTGF and PC Ⅲ may be considered as a confirmatory diagnostic marker for liver fibrosis.

OBJECTIVE:To observe clinical efficacy and safety of Ebastine tablet combined with Chushi zhiyang ointment in the treatment of hand keratinizing chapped eczema. METHODS:135 cases of hand keratinizing chapped eczema were divided into control group A(45 cases),control group B(43 cases)and treatment group(47 cases)according to treatment regimen. Control group A was orally given Ebastine tablet,10 mg each time,qd;control group B was given Chushi zhiyang ointment alone,twice a day,morning and evening,applying thin layer of ointment on the affected area;treatment group was given same dose of Ebastine tablet orally and applied Chushi zhiyang ointment on the affected area. 3 groups received treatment for consecutive 4 weeks. Clinical efficacies of 3 groups were observed as well as the scores of pruritus,skin lesion area,keratinization,rhagades and VAS before and after treatment. The occurrence of ADR was compared among 3 groups. RESULTS:The total effective rate of treatment group was 68.09%,which was significantly higher than that of group A(42.22%)and control group B(16.28%),with statistical significance(P<0.05). There was no statistical significance in the scores of pruritus,skin lesion area,keratinization,rhagades and VAS among 3 groups before treatment(P>0.05). After treatment,above scores of 3 groups decreased significantly,and those of treatment group were significant-ly lower than those of control group A and B,with statistical significance(P<0.05). There was no statistical significance in the inci-dence of ADR among 3 groups(P>0.05). CONCLUSIONS:Ebastine tablet combined with Chushi zhiyang ointment is effective for hand keratinizing chapped eczema,and can significantly improve the skin of patients with good safety.

Objective: To investigate the association between the CYP3A5 genetic polymorphism and the serum concentrations of carbamazepine (CBZ), to provide guidance for individualized drug dosing. Methods: Eighty-four epilepsy patients taking CBZ were included in this study. Their clinical data were recorded and CBZ serum concentrations were measured. The CYP3A5 6986 genetic polymorphism was assessed using a polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) assay. Patients were divided according to genotype into CYP3A5 expressor (CYP3A5*1/*1 genotype and CYP3A5*1/*3 genotypes) and non-expressor groups (CYP3A5*3/*3). The two groups were compared for the total dose of CBZ, dose of CBZ/kg body weight, serum drug concentration, dose-corrected serum concentration, and standardized serum concentration. Results: The total dose of CBZ and the dose of CBZ/kg body weight was higher in the CYP3A5 expressor group than the non-expressor (P = 0.043 and P = 0.014, respectively). The dose-corrected and standardized serum concentrations were lower in the CYP3A5 expressor group than the non-expressor (P = 0.001 and P < 0.001, respectively). There was however, no signifi cant difference in serum drug concentration between the two groups (P = 0.487). Conclusions: There was a close relationship between CYP3A5 genetic polymorphism and the serum concentrations of carbamazepine.

Objective To explore the expression of Bcl-6 mRNA in the Tfh cells of HIV/AIDS patients and the relationship between Bcl-6 mRNA and the progression of HIV/AIDS.Methods This experiment chose 60 patients who were confirmed by HIV antibody test positive,during May 2014 to November from AIDS Research Institute in the First Affiliated Hospi-tal,Henan College of Traditional Chinese Medicine.According to the amount of CD4+T cells,the patients with HIV/AIDS were divided into A(CD4<200 cells/μl),B(200 cells/μl500 cells/μl)three groups.The Tfh cells expressed CD4+ CXCR5 + ICOS+ and lymphocyte subpopulation including T,B and NK cells were detected by flow cytometry (FCM).The expression of Bcl-6 mRNA levels were detected by reverse transcription-polymerase chain reaction (RT-PCR).The association between Tfh cells and Bcl-6 mRNA,B cells were analyzed.Results The expression of Bcl-6 mRNA from patients of A,B and C three groups was increased than in healthy individuals (2.94±0.91,2.27±0.62,2.15± 0.351,P <0.05).The percent of Tfh cells from group A patients was higher than group C patients (5.88±3.01 vs 1.26± 0.87,P =0.032)and also the healthy control group (5.88±3.01 vs 0.78±0.42,P =0.004).The percentage of NK cells and B cells in HIV/AIDS patients was no statistically significant.Correlation analysis showed that there was positive corre-lation between the proportion of Tfh cells and Bcl-6 mRNA (r=0.799,P =0.000).And Tfh cells were observed no relation-ship with B cells (r=-0.083,P =0.657).Conclusion The changes of Bcl-6 mRNA and Tfh cells may be related to the progression of HIV/AIDS.
