Objective To investigate the relationship between thyroid hormone levels and carotid artery disease in maintenance hemodialysis ( MHD ) patients and evaluate its value. Methods Clinical data of one hundred and twenty?one MHD patients during January 2014 to July 2016 in Yanan University Affiliated Hospital were collected. The patients were divided into the normal carotid artery group and the carotid artery lesion group according to whether there was plaque or stenosis in the carotid artery ultrasonography. Clinical data related to the carotid artery lesions was collected, and the single factors that may affect the carotid artery lesions were analyzed,multivariate logistic regression was used to analyze independent risk factors for carotid artery disease, and the greatest independent risk factor of OR value was used to establish a ROC curve for evaluating carotid atherosclerosis in patients with MHD. Results The levels of serum calcium, TC, TG, LDL?C, TSH, CRP and Hcy in the carotid artery group were higher than those in the normal group ( P<0. 05 ) . The levels of serum phosphorus and FT3 in the lesion group were lower than those in the normal group ( P<0. 05 ) . Multivariate logistic regression analysis of risk factors for carotid atherosclerosis showed that CRP ( OR=1. 620,95%CI1. 288-2. 038,P=0. 048),Hcy (OR=1. 976,95%CI 1. 135?3. 441,P=0. 021),FT3 (OR=2. 521,95%CI 1. 584-4. 012,P=0. 017) were independent risk factors for carotid artery disease. FT3 evaluation of the ROC curve showed AUC=0. 848,P=0. 000,the cut?off value was 3. 705pmol/L,the diagnostic sensitivity was 0. 670,and the specificity was 0. 879. CRP valuation of the ROC curve suggested that AUC=0. 619,P=0. 000,the cut?off value was 16. 215 mg/L,the diagnostic sensitivity was 0. 932 and the specificity was 0. 333. Hcy evaluation of the ROC curve showed AUC=0. 767,P=0. 000,the cut?off value was 12. 565μmol/L,the diagnostic sensitivity was 0. 784 and the specificity was 0. 881. Conclusion Low concentration of FT3,high concentration of Hcy and high concentration of CRP in MHD patients were independent risk factors for carotid artery disease. The use of FT3 to evaluation the carotid atherosclerosis has a certain value.

Objective To investigate the influence of mental intervention on the self-image of breast cancer patients.Methods Fifty patients with breast cancer who were hospitalized in our hospital from January to September,2015 were enrolled as the control group in the study,where routine nursing intervention,health education on disease related knowledge and psychological nursing were carried out.During October 2015 to June 2016,50 patients with breast cancer were enrolled as the observation group,where psychological awareness intervention was carried out apart from the routine nursing intervention.The self-image level of breast cancer patients from the two groups was evaluated by self-image questionnaire for breast cancer patients (BIBCQ).Result After intervention,the scores on self-image in the observation group were significantly higher than those in the control group (P＜0.05).Conclusion Mental intervention can improve the self-image of breast cancer patients and help improve their quality of life.

Objective To evaluate the efficacy of adjustable oral appliance (OA) on ventilation of patients with obstructive sleep apnea hypopnea syndrome (OSAHS).Methods Databases were searched from Junuary 1990 to July 2014 for randomized controlled trials on the use of adjustable OA for the promotion of ventilation in OSAHS.Meta analysis was performed with RevMan5.2 software,and descriptive analysis of the data that could not be converted and merged was performed.Results Totally 6 RCTs involved,including 1 109 patients,which involved 4 random parallel controlled trials and 2 random crossover controlled trials.Meta-analysis showed that adjustable OA were associated with a decreased apnea-hypopnea index(AHI) [fixed effect model,WMD=-2.38,95％CI (-3.59--1.17),P＜0.01] and an improvement in minimum arterial oxygen saturation (SaO2)[randomized effect model,WMD=3.09,95％CI(1.16-5.02),P＜0.01] of OSAHS patients.The descriptive analysis showed that the difference in the sleep score was not statistically significant because the data could not be converted.Conclusions Compared to fixed oral appliance,adjustable oral appliance produced greater effect in reduction of AHI and the improvement in minimum SaO2,but the sleep score is not improved significantly,the large sample and multi-center randomized controlled test needs to be designed for the verification of comprehensive effect of adjustable oral appliance.

Objective To assess the effect and safety of lanthanum carbonate vs conventional phosphate binders for hyperphosphatemia in patients undergoing maintenance hemodialysis.Methods According to the collaborative search strategy,MEDLINE (1996 to 2012.12),EBCO (1996 to 2012.12),the clinical control test database of Cochrane Library and Chinese Wanfang database (1996to 2012.12) were searched.Related literature,whether Published or not and meeting summary included,were searched by hand.Quality assessment and data extraction were conducted by two independent investigators.Meta-analysis was conducted by RevMan 5.0.The following outcomes were assessed:serum phosphorus levels,serum iPTH levels,serum calcium levels and adverse events.Results were expressed as OR with 95％ confidence interval for dichotomous outcomes and WMD with 95％ confidence interval for continuous outcomes.Results A total of 10 reports were identified which met the inclusion criteria.The meta-analysis showed that the efficacy of treating hyperparathyroidism in hemodialysis patients was similar between lanthanum carbonate and conventional phosphate binders (WMD =-0.06,95％ CI-0.27 to 0.15,P =0.57) and the incidences of discontinuing due to adverse events were also similar.However,there were fewer hypercalcemic episodes and lower serum calcium levels in the lanthanum carbonate group compared to calcium-based phosphorus binders group.Conclusion Lanthanum carbonate is effective and well tolerated in treating hyperphosphatemia in hemodialysis patients with fewer hypercalcemia and lower serum calcium levels compared to calciumbased phosphate binders.

Objective To explore the changes of programmed death receptor-1 (PD-1) in chronic hepatitis B (CHB) patients with different baseline of hepatitis B virus (HBV) DNA levels after treatment with adefovir dipivoxil (ADV).Methods One hundred CHB patients with positive hepatitis B e antigen (HBeAg),1 × 104 copy/mL≤HBV DNA≤1 × 107 copy/mL,and positive human leukocyte antigen-A2 were divided into two groups according to the baseline HBV DNA level:47 cases in low virus load group whose HBV DNA level was ≤1 × 105 copy/mL; 53 cases in high virus load group whose HBV DNA level was＞1 × 105 copy/mL.Both groups were treated with ADV 10 mg/d.Serum HBV DNA,HBeAg seroconversion rate,alanine aminotransferase (ALT) and total bilirubin (TBil) levels of both groups before treatment and 12 months after treatment were compared.Flow cytometry was used to test peripheral blood HBV-specific cytotoxic T lymphocyte (CTL) surface PD-1 and peripheral blood HBV-specific CTL level.Categorical data were tested by x2 test; quantitative data was compared with t-test.Results Peripheral blood HBV-specific CTL surface PD-1 of CHB patients in low virus load group was 20.17 ％±1.69％,which was lower than that in high virus load group (41.38％±2.30％,t =53.02,P＜0.01) ; peripheral blood HBV specific CTL levels in two groups were 0.37％±0.02％ and 0.17％± 0.02％,respectively (t=50.47,P＜0.01) ; ALT and TBil levels in low virus load group were both lower than those of high virus load group (t=13.07,P＜0.01; t=5.06,P＜0.01).Twelve months after treatment,HBV DNA of 25 cases (53.2％) in low virus load group and 10 cases (18.9％) in high virus load group were lower than the detectable level (HBV DNA＜500 copy/mL,x2 =12.89,P＜0.01);HBeAg seroconversion was achieved in 15 cases(31.9％) and 1 case (1.9％),respectively (x2 =16.72,P＜0.01) ; peripheral blood HBV-specific CTL surface PD-1 expression levels were 9.00 ％ ±1.38 ％ and 29.40 ％ ± 3.76 ％,respectively (t =36.80,P＜ 0.01) ; peripheral blood HBV-specific CTL levels were 0.65％±0.10％ and0.48％±0.07％,respectively (t=9.61,P＜0.01).Conclusions After treatment with ADV,along with the decrease of HBV DNA load,HBV-specific CTL surface PD-1 expression decreases,while HBV-specific CTL level increases.The changes in low virus load group are much more remarkable.

Objective To study the spatial variation of T2 relaxation time of cartilage of knee in healthy adults.Methods T2 values of cartilage of knee in 21 asymptomatic young male adults ( age ranged 24 to 39 years ; mean age , 30 years) were calculated by using a multiecho,spin-echo MR imaging sequence at 1.5T MR scanner on sagittal T2 maps,including the patellar,distal femoral weight and non-weight-bearing as well as proximal tibial weight-bearing cartilages,the differences in the spatial variation between them were analysed using F test.Results All 21 asymptomatic volunteers demonstrated a consistent pattern of spatial variation of T2 values cartilage of knee with longer T2 values near the subchondral bone,decreased in deep zoon and increased in articular surface , there was difference between them (F=70.892 , P＜0.05 ) . The greates spatial variation occurred in the patella.T2 value(26.56 ms±4.4 ms) in the deeper zoon of cartilage of the patella was obviously lower than that of the weight-and non-weight-bearing articular cartilage (P = 0.001 ) . Lateral femoral weight-bearing articular cartilage showed lower T2 value ( 35.2 ms ± 6.31 ms) in the outer transitional superficial zone than thatof the patella and non-weight-bearing cartilage,P=0.002,P=0.000 respectively.Lateral tibial weight-bearing articular cartilage showed showed lower T2 value(37.11 ms±6.6 ms)in the outer transitional superficial zone than that of non-weight-bearing cartilage(P=0.000). Conclusion The spatial variation of T2 relaxation time of cartilage of knee in the vivo in the asymptomatic young adults is like slightly concave curve at 1.5T MR system,that is of reference value in study of degenerative osteoarthritis.

Objective To investigate the changes of pathogens and antimicrobial susceptibility in patients with biliary tract infection during the past 30 years.Methods During the periods of 1981-1984,1988-1998 and 2003-2013,each 100 patients treated with common bile duct exploratoration were selected from every period.Biopsied bile specimens were performed with bacteria culture and antimicrobial susceptibility tests.This study reviewed the changes in bilary pathogens and antimicrobial susceptibility test.Results From 1981 to 1984,the most common pathogens were Escherichia coli (59.2％) and Klebsiella pneumonia (28.9％).Mixed infection of these pathogens accounted for 16.9％.From 1988 to 1998,the types of pathogens significandy increased.Escherichia coli (33.1％) and Klebsiella pneumonia (16.5％) accounted for less than 50％.Mixed infection with Escherichia coli and Pseudomonas aeruginosa was the most common type.From 2003 to 2013,gram-negative bacteria were still the main pathogens,accounting for 61.8％.Escherichia coli and Pseudomonas aeruginosa accounted for 20.1％ and 10.4％,respectively.Gram-positive bacteria increased sigrnificantly.Enterococcusfaecium (22.2％) ranked the first.Mixed infection increased (36％),of which more than 50％ was mixed pathogens of Escherichia coli and Enterococcusfaecium.The incidence of fungi infection also increased (5.6％).Conclusions There was a remarkable change of pathogen category in the biliary infections over the past years.With an increase of gram-positive bacteria and fungi infection in clinical practice,antimicrobial susceptability results could be considered in choosing appropriate drug to avoid bacterial resistance.
