Objective:To investigate the expressions of tissue inhibitor of matrix metalloproteinase-1 (TIMP1) and fibronectin 1 (FN1) in pregnancy associated breast cancer (PABC) and their correlations with expression of E-cadherin (E-cad).Methods:The clinicopathological data of 55 PABC patients in Binzhou People's Hospital Affiliated to Shandong First Medical University from January 2011 to December 2020 were retrospectively analyzed. Immunohistochemistry was used to detect expressions of TIMP1, FN1 and E-cad in cancer tissues and corresponding paracancerous tissues (>3 cm from the edge of the tumor foci). The expressions of TIMP1 and FN1 proteins in fresh intraoperative frozen cancer tissues and paracancerous tissues of 10 PABC patients were detected by Western blotting. The correlations of TIMP1 and FN1 expressions with clinicopathological characteristics of patients were analyzed by χ2 test, the correlation of TIMP1 and FN1 expressions with E-cad expression was analyzed by Spearman method, and the correlation of TIMP1 and FN1 expressions with survival was analyzed by Kaplan-Meier method. Results:The positive rates of TIMP1 and FN1 in PABC tissues were 72.7% (40/55) and 58.2% (32/55), and 25.5% (14/55) and 18.2% (10/55) in paracancerous tissues, and the differences were statistically significant ( χ2 values were 24.59 and 18.64, both P < 0.001). The results of Western blotting showed that the relative expressions of TIMP1 and FN1 proteins in the fresh cancer tissues of 10 PABC patients was higher than those in the corresponding paracancerous tissues (1.60±0.76 vs. 0.62±0.29, 1.31±0.62 vs. 0.44±0.15), and the differences were statistically significant ( t values were 5.92 and 4.86, both P < 0.001). The expressions of TIMP1 and FN1 in PABC tissues were correlated with estrogen receptor expression, Ki-67 positivity index, TNM stage and lymph node metastasis (all P < 0.05). The expressions of TIMP1 and FN1 were negatively correlated with expression of E-cad in PABC ( r values were -0.471 and -0.432, both P < 0.001). Five cases were lost to follow-up, and the remaining 50 cases had a median follow-up time of 43 months (12-90 months). Among the 50 cases, 36 cases were TMP1-positive and 29 cases were FN1-positive. The overall survival of TIMP1-negative group and FN1-negative group were better than those of the corresponding positive group ( χ2 values were 4.49 and 6.06, both P < 0.05); the median overall survival time of TIMP1-positive group and FN1-positive group were 51 months (95% CI 37-65 months) and 43 months (95% CI 32-53 months), while that of TIMP1-negative group and FN1-negative group were 89 months (95% CI 84-93 months) and 87 months (95% CI 85-92 months). Conclusions:TIMP1 and FN1 expressions are elevated in PABC tissues and negatively correlated with E-cad expression, TIMP1 and FN1 may be involved in PABC invasion through epithelial-mesenchymal transition and affect the prognosis of patients.

Objective@#To investigate the influence of five-in-one management mode(standardized asthma treatment, asthma diary, peak expiratory flow (PEF) monitoring, reasonable diet and physical exercise) on disease prevention and control of school children with asthma.@*Methods@#From April to October 2018, 70 children with asthma in clinical remission were selected from Affiliated Hospital of Qingdao University using randomized controlled study design. These children were randomly divided into study group and control group, with 35 cases in each group. In the study group, 5 cases were lost to follow-up, and 30 cases were actually enrolled. In the control group, 6 cases were lost to follow-up, and 29 cases were actually enrolled. Children in the control group received routine medication and regular outpatient consultation, and children in the study group received the five-in-one asthma management model. In the first time of seeing a doctor, after 3 months and 6 months of follow-up, asthma control test score, medication compliance index score and lung function index (forced expiratory volume in 1 second (FEV1), PEF were evaluated respectively.Parental satisfaction, asthma acute episodes, weight, height and biochemical index were recorded during the 6 months of follow-up. Pulmonary function index, asthma control score and body mass index of overweight children with asthma were compared with t-test, medication compliance was compared with chi-square test, and the rank sum test was used for the comparison of the number of emergency visits of asthma attacks and parents′ satisfaction.@*Results@#A total of 59 children with asthma were included, among them 30 were in the study group (8.1±1.5) years old and 29 in the control group (9.2±1.1) years old. After 3 months of follow-up, FEV1, PEF, asthma control score in the study group were (86.3±1.5)%, (83.3±2.4)%, (24.7±2.6) points respectively; and in the control group, FEV1, PEF, asthma control score were (84.4±2.5)%, (82.2±1.9)%, (21.1±1.3) points respectively. The indicators in the study group were higher than those in the control group (t=3.62, 1.97, 6.64, P<0.05). After 6 months of follow-up, FEV1, PEF, asthma control score in the study group were (88.4±2.3)%, (85.4±2.2)%, (26.8±1.8) points respectively; and in the control group, FEV1, PEF, asthma control score were (85.5±1.9)%, (83.2±1.7)%, (22.5±1.4) points respectively. The indicators in the study group were significantly higher than those in the control group (t=5.34, 4.24, 10.41, P<0.05). During the 6-month follow up, the number of emergency visits of asthma attacks in the study group and in the control group were 0.42(0.36, 0.51) and 0.92(0.72, 1.27) respectively. The indicator in the study group was significantly lower than that in the control group (Z=3.21, P<0.05). After 3 months of follow-up, the proportions of children with good compliance in the study group and control group were 67% (20/30) and 62% (18/29), the proportions of poor compliance were 27% (8/30) and 34% (10/29), the proportions of non-compliance were 7% (2/30) and 7% (2/29). There were no statistically significant differences (χ2=0.14, 0.43, 0.00, P=0.71, 0.51, 0.97). After 6 months of follow-up, the proportions of children with good compliance in the study group and control group were 87% (26/30) and 69% (20/29), the proportion of poor compliance were 10% (3/30) and 28% (8/29), the proportion of non-compliance were 3% (1/30) and 7% (2/29), There were no statistically significant differences (χ2=2.70, 3.00, 0.39, P=0.10, 0.08, 0.53). After 6 months of follow-up, the number of great satisfaction, satisfaction and dissatisfaction in the study group were 20, 10 and 0 respectively, the satisfaction rate was 100%, meanwhile those indicators in the control group were 4, 15 and 10 respectively, the satisfaction rate was 66%, The indicator in the study group was significantly higher than that in the control group (Z=4.60, P<0.05).@*Conclusions@#The application of "five-in-one" asthma management model (standardized asthma treatment, asthma diary, PEF monitoring, reasonable diet and physical exercise) for school-age children with asthma can significantly improve lung function, as well as reduce the number of acute asthma attacks.

Objective: To investigate the expression of Topo Ha and Ki67 and its clinical significance
Methods: The clinical pathological data of one hundred and sixteen invasive breast cancer patients who were admitted into our hospital from July 2013 to December 2015 and underwent radical mastectomy were retrospectively analyzed. The expression of topoispmerase [Topo] lla and Ki67 was detected using immunohistochemical method, and the correlation between the two kinds of proteins and the general clinical pathological characteristics of the patients was analyzed
Results: The positive expression rates of Topo Ha and Ki67 in breast cancer were 58.6% and 75% respectively
The expression of Topo lla was in no apparent correlation with the age, tumor size, estrogen receptor [ER], progesterone receptor [PR] and human epidermal growth factor receptor 2 [HER-2] [P>0.05], but in a correlation with the number of metastatic lymph glands [P<0.05]. The expression of Ki67 was in no apparent correlation with the age, tumor size, EP and HER-2, but in a correlation with the number of metastatic lymph glands and PR [P<0.05]. The multi-factor logistic regression analysis results suggested that the number of metastatic lymph glands was the independent predictive factor of Topo lla positive expression and the number of metastatic lymph glands and PR protein expression state are the independent predictive factors of Ki67 positive expression
Conclusion: Topo lla and Ki67 can be regarded as the indicators for reflecting the proliferation activity of tumor cells, and the detection of Topo lla and Ki67 expression is of great significance to the prognosis evaluation of breast cancer patients and clinical treatment
