Wnt/β-catenin signaling pathway plays an important role in the proliferation, growth, invasion, and metastasis of human cancers. Moreover, β-catenin/T-cell factor 4 (TCF4) interaction regulates the transcription of the key oncogenes in Wnt/β-catenin signaling pathway. Therefore, β-catenin/TCF4 interaction would be a promising therapeutic target for the development of highly selective anticancer agents. At present, most ongoing small-molecule inhibitors targeting β-catenin/TCF4 interaction, including PKF222-815, iCRT3/5/14, LF3, and sanguinarine, have been developed in preclinical studies for human cancer therapeutics. In this review, we summarized the research advances of up-to date inhibitors targeting β-catenin/TCF4 interaction, including the molecular structure and cellular functions of β-catenin in canonical Wnt signaling pathway. This review holds a hopeful avenue for the development of novel and highly selective Wnt inhibitors targeting β-catenin/TCF4 interaction for future anticancer strategy.

Objective To evaluate the application value of UF-1000i automated urine formed elements analyzer in the diagnosis of urinary tract infection. Methods 150 urine specimens were analyzed using the UF-1000i in parallel with detection of leukocyte, yeast-like fungus, and bacteria. These detection results were collected for evaluation of urinary tract infection and scatter grams were recorded. At the same time, these samples were cultured for bacterial identification, which results were compared with that of the UF-1000i. The clinical diagnose criteria of the UTI was performed as golden standard. As compare with results obtained with UF-1000i, the sensitivity and specificity of UF-1000i for diagnosis of urinary tract infection were evaluated, and the consistency were analyzed among scatter grams, bacterial culture and final diagnosis. Results The statistical results from 146 specimens showed that the positive rate of UF-1000i was 32. 9% (48/146), the positive rate of urine culture is 28. 8% (42/146). There was no significant statistical difference found (χ2 = 1.79 ,P = 0. 18 )and Kappa test showed a considerable consistency (K = 0. 775 6). The UF-1000i detection results showed the sensitivity 76. 0% ( 38/50 ), specificity 89. 6% ( 86/96 ), positive predictive value 79. 2% ( 38/48 ) and negative predictive value 87. 8% ( 86/98 ), respectively. The distribution of coccus and bacilli obtained from the UF-1000i testing was basically in accordance with the results of bacterial culture. Conclusion The "UTI-information" of UF-1000i is very important for the diagnosis of urinary tract infections.

OBJECTIVE: To analyze the microbial contamination and investigate the bacteriostatic efficacy of compound balloonflowers and ephedrine syrup(Ⅱ). METHODS: The compound balloonflowers and ephedrine syrup(Ⅱ) was analyzed for the bacteriostatic efficacy, content of bacteriostatic agent and C18 column was adopted with gradient elution. The mobile phase consisted of 0.02 mol•L-1 ammonium acetate solution and methanol. The detective wavelength was set at 255 nm. The contaminating bacteria detected in the samples were identified by VITEK2 Campact, MALDI-TOF-MS and 16S rRNA sequencing, and homology analysis was conducted for the contaminating bacteria in the samples from the same enterprise. RESULTS: The bacteriostatic efficacy of the products of one enterprise did not meet the requirements of Chinese Pharmacopoeia(2015 edition). There were excessive and uneven contamination of microorganisms in the samples. The dosages of bacteriostatic agents in some enterprises did not conform to the standard requirements. CONCLUSION: Production enterprises should strictly control the dosages of bacteriostatic agents and the stability of the production process, and strengthen the monitoring of the sterilization effect of the whole production process to improve product quality.

Objective:To understand the status and association of health literacy and self-management ability of hypertensive patients in the community and to provide reference for further intervention research.Methods:From June 2019 to October 2019, a random number table method was used to randomly select multiple streets or towns/townships, and then 401 residents in the community or village aged above 18 years of age diagnosed as hypertension were selected as the subjects of this study. The general data questionnaire, high blood pressure-health literacy scale into Chinese(C-HBP-HLS) and hypertension patients self-management behavior rating scale(HPSMBRS)were used to conduct one-to-one field survey. SPSS 24.0 was used to analyze the scores of health literacy and self-management behavior of patients with hypertension. SAS 9.4 was used to analyze the canonical correlation between health literacy and self-management behavior of patients with hypertension.Results:The score of health literacy and self-management ability were (38.94±17.56) points and (129.45±16.53) points, respectively.The results of canonical correlation analysis showed that the canonical correlation coefficient between health literacy and self-management behavior reached 0.57, which was mainly reflected in the great correlation between " drug label" and " diet management" .Conclusion:Attention should be paid to the positive effect of health literacy on self-management ability, and further intervention research should take the " drug label" and " written health literacy" dimensions of health literacy as entry points to effectively improve the self-management ability of hypertension patients in the community.

Objective To evaluate the clinical significance of prenatal ultrasonography in diagnosis of retroaortic left innominate vein ( LINV ) . Methods Thirty fetus with retroaortic LINV were involved , including 17 cases of isolated retroaortic LINV and 13 cases of complicated retroaortic LINV . Three-vessel and trachea ( 3VT ) view was focused in the routine second trimester ultrasound screening to observe whether LINV existing or not . And then the transducer was rotated to the fetal sagittal view to assess the relationship between LINV and aortic arch and the convergence of left subclavian vein and left internal jugular vein into the LINV . Results The characteristic feature of retroaortic LINV was the LINV converge into right superior vena cava ( SVC) under the aortic arch ,not above the aortic arch . The most important plane to detect the retroaortic LINV was the 3VT view ,which revealed the abnormal vein lying to the left of pulmonary artery . The abnormal vein then could be traced and revealed its connection with the right SVC beneath the aortic arch on the transverse plane inferior to the 3VT view and on the fetal sagittal plane . Conclusions The whole course of retroaortic LINV can be revealed by ultrasound prenatally ,which can not only account for the abnormal vein to the left of pulmonary artery on 3VT view ,but also play an important role in surgery decision and future cardiac intervention treatment .
