Purpose To investigate the expression of miR-134 in breast carcinoma and its c1inica1 significance,and to ana1yze the as-sociation between its expression with bio-markers of epithe1ia1-mesenchyma1 transition( EMT). Methods The expression of miR-134 in 97 breast cancer samp1es was detected by in situ hybridization and the expression of E-cadherin,N-cadherin,and vimentin was de-tected by MaxVision two-step method of immunohistochemistry,to ana1yze the re1ationship between their expression and c1inicopatho1og-ica1 characteristics. Results The expression of miR-134 in breast cancer was negative1y associated with higher histo1ogica1 grade, HER-2 overexpression,1ow expression of E-cadherin as we11 as high expression of N-cadherin and vimentin. Both 1ow-expression of E-cadherin and up-expression of N-cadherin and vimentin in breast cancer were positive1y corre1ated with higher histo1ogica1 grade,1ymph node invo1vement and HER-2 overexpression,whi1e negative1y associated with the expression of ER and PR. Conclusion The expres-sion of miR-134 in breast cancer tissue is negative1y re1ated to both the ma1ignant progression and EMT,indicating that it might be a potentia1 bio-marker for breast cancer.

Objective: To understand the current situation and impacts of household factors on of unhealthy dietary habits among preschool children, and to provide reference for preventing the occurrence of unhealthy dietary habits of preschool children. Methods: By using stratified random cluster sampling method, the study selected 1 070 children aged 3-6 years in 7 kindergartens in Urumqi. Household general information , children’s dietary behavior and parenting environment was collected through parent questionnaire survey. Results: The prevalence rate of unhealthy dietary habits among preschool children was 32.71%. Multifactor Logistic regression analysis showed that the unhealthy dietary habits of preschool children were negatively correlated to the following factors, including age of children [β=-0.32, 95%CI=(0.62,0.86)] , gender[β=-0.33,95%CI=(0.53,0.97)], educational level of mothers [β=0.94, 95%CI=(1.79,3.68)] , type of fanmily [β=0.64, 95%CI=(1.414,2.522)] and the scores of social adaptation/selfcare and environmental atmosphere in the family nurturing environment [β=-0.07, 95%CI=(0.90,0.97); β=-0.21, 95%CI=(0.76,0.87)]. Conclusion The cultivation of the dietary habits should pay more attention on younger children and boys, and the enhancement of health education on the children’s eating behaviors among mothers with lower education background and the primary child caregivers in the stem family. Family nurturing environment should be actively improved, in order to prevent the occurrence of children’s unhealthy dietary habits.

Objective:To detect the expression of BTLA on Treg cells of HIV-infected patients and investigate the role of BTLA in HIV infection.Methods: Forty-four HIV-1-infected patients (twenty-four early HIV infection,fourteen chronic HIV-infected patients with CD4+ T counts> 200 cells/μl,AIDS patients with CD4+T counts<200 cells/μl) and nine healthy people served as normal controls were selected to detect the expression of BTLA on Treg cells by flow cytometry.The correlations between BTLA expression on Treg cells and disease progression or immune activation were studied.Results: There was a higher percentage of BTLA on Treg cells in chronic HIV patients and AIDS patients than that in early HIV infected patients(P<0.05,P<0.01),and the expression of BTLA on Treg cells in AIDS patients was higher than that in normal controls(P<0.05).The expression of BTLA on Treg cells was negatively correlated with CD4+T lymphocyte counts and positively correlated with viral load (P<0.001,P<0.01).The percentage of BTLA on Treg cells was positively correlated with CD4+CD38+T lymphocytes and CD4+HLA-DR+T lymphocytes(P<0.001,P<0.001).Conclusion: Increased BTLA expression on HIV-infected Treg cells is associated with disease progression,suggesting that it may accelerate disease progression by enhancing Treg cells inhibitory function and may provide intervention information for HIV infection in the future.

Objective To explore the cognition and demand status of order oriented nursing talents in different hospitals in Xinjiang,so as to provide a scientific basis for establishing the model in Xinjiang. Methods Using qualitative research methods and purposive sampling, 12 nursing directors from different grades of hospitals in North and South Xinjiang were selected and semi structured in-depth interviews were conducted from September 2016 to October 2016. Colaizzi phenomenological seven step analysis method was used to analyze the data and get the theme. Results Through analysis, the three themes of different types of hospitals in Xinjiang were put forward: there are different levels of hospitals in order to model the demand of nursing personnel training;different levels of hospital nursing students'needs of different orders;the hospital expects to establish order type talent training hospital-school cooperation steering committee. Conclusions Xinjiang area hospitals of different levels to construct the pattern of the urgent need for the"order"of nursing personnel training,to meet the needs of nursing professionals of different levels of hospitals, so as to improve the overall level of nursing staff, to provide quality health services along the Silk Road and the surrounding countries.

OBJECTIVE: To study the expression of Survivin, Caspase-3 and p53 in surgical margin of laryngeal squamous cell carcinoma (LSCC), and their clinical significance and relationship. METHOD: Immunohistochemistry method was used to detect the expression of Survivin, Caspase-3 and p53 in 116 cases of surgical margin of LSCC. RESULT: According to the recurrence, the patients were divided into four group, recurrence within one year, between one year to three years, between three to five years, more than 5 years (include no recurrence). The expression rate of survivin were 92.9%, 85.0%, 50.0% and 21.1% (P < 0.01) in four groups, respectively. The expression rate of Caspase-3 were 50.0%, 50.0%, 66.7% and 89.5% (P < 0.01). The expression rate of p53 were 57.1%, 37.5%, 45.8% and 18.4% (P < 0.05). The expression rate of survivin, caspase-3 and p53 in four groups, respectively, there were significant differences (P < 0.05). CONCLUSION Expression of Survivin, Caspase-3 and p53 in surgical margin of LSCC may play an important role in the tumorigenesis and development of laryngeal carcinoma. They are feasible for early diagnosis and prognosis estimation.

Objective:To investigate the predictive value of different body obesity measures for non-alcoholic fatty liver disease (NAFLD).Methods:It was a cross-sectional study. The present study was a case-control study involving 553 subjects who underwent physical examination from January to April 2022. The subjects were divided into NAFLD group ( n=321 cases) and control group ( n=232 cases) according to abdominal ultrasound imaging parameters. All subjects completed a general information questionnaire, liver ultrasound examination, serum biochemical indices and physical measurements. Logistic regression model was used to analyze the correlation between human obesity measures (neck circumference, triceps skinfold thickness (TSF),body mass index (BMI), waist-to-hip ratio, lipid accumulation index (LAP), visceral fat index (VAI), body roundness index (BRI) and a body shape index (ABSI)) and NAFLD. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the predictive value of single and combined measures of obesity for NAFLD. Results:The subjects were stratified by gender, and the quartile levels of BMI, neck circumference, TSF, waist-to-hip ratio, LAP, VAI and BRI were all correlated with NAFLD in both male and female (all P<0.05). After further adjustment for confounding factors, compared with those in group Q 1, group Q 4 of the above-mentioned indexes still had higher odds ratios ( P<0.05). The AUC value of LAP in predicting NAFLD was the largest in both men and women, which was 0.836(0.788-0.876) and 0.885(0.839-0.921), and the cut-off value was 41.93 and 33.27, respectively. There was no significant difference in AUC of ROC predicting NAFLD among LAP, BRI and BMI ( P>0.05). The AUC of ABSI in predicting NAFLD was less than 0.7(namely 0.584(0.525-0.641) and 0.679(0.618-0.735) in men and women, respectively), which indicated poor predictive performance for NAFLD. In the pairwise combination index, the AUC of ROC predicting NAFLD with TSF+LAP in male was the largest, which was 0.864(0.819-0.901), and there was statistical significance when compared with BRI (AUC=0.818(0.769-0.860)) and BMI (AUC=0.816(0.767-0.858)) ( P<0.05), but there was no statistical significance when compared with LAP (AUC=0.836(0.788-0.876)) ( P>0.05). The AUC of ROC predicting NAFLD with VAI+LAP in women was the largest, it was 0.894(0.849-0.928), there was statistical significance when compared with BMI (AUC=0.849(0.799-0.890)) ( P<0.05), but there was no statistical significance when compared with LAP (AUC=0.885(0.839-0.921)) and BRI (AUC=0.870(0.822-0.908)) ( P>0.05). Conclusion:BMI, neck circumference, TSF, waist-to-hip ratio, LAP, VAI and BRI all have good predictive value for NAFLD.
