Ambulatory blood pressure monitoring (ABPM), which can reflect the 24h mean blood pressure, precisely characterize changes in blood pressure throughout daily activities and circadian rhythm, has been found to be superior to traditional blood pressure monitoring. ABPM is in more widespread use in recognition of children's white coat hypertension and masked hypertension, predicting target-organ damage, assessing the efficacy of antihypertentive drug treatment and distinguishing primary hypertension from secondary hypertension.The article summarizes the clinical applications of ABPM in pediatrics.

Triple-negative breast cancers (TNBC) comprise a heterogeneous group of tumors characterized by poor survival and lack of targeted therapeutics. In recent years, androgen receptor (AR) has been demonstrated to play an important role in the genesis and development of TNBC. There has been increased interest in the role of AR in TNBC and AR-targeting has been introduced as a novel therapeutic option for TNBC. This review offers an overview of the relationship between AR expression and TNBC, and provides insights into the novel drugs in the development for targeting this signaling pathway.

Objective:To explore the language deficits in a single case of posterior aphasic to test the dual-system model of language processing and provide neurolinguistic basis for clinical language therapy.Method:A circumscribed posterior aphasic was selected,whose language data were collected through spontaneous talk,WAB test,and other language production tasks including picture-naming and sentence repetition.The language data were analyzed with the emphasis on syntax-lexicon dissociation and noun-verb dissociation.Result:For the posterior aphasic,lexicon was severely impaired while syntax was preserved relatively well;in comparison to lexical production,lexical comprehension was preserved better;noun-verb dissociation,especially NSD,was discovered.Conclusion:The syntax-lexicon dissociation and the relevant noun-verb dissociation can serve as powerful evidence for the dual-system model of language processing,and throw light on language therapy for posterior aphasics.

Objective To clarify the involvement of the free fatty acids(FFA)and lipid peroxida-tion in rat pancreatic tissue during the development of pancreatic injuries inducecd by long-term high-fat diet.Mehtods The male Sprague-Dawley rats (n=72) were randomized into 6 groups (n=12).One group (group control) received standard chow for 18 weeks, the other five groups (group HFD) were fed with a high-fat diet respectively for 2, 4, 6, 10 and 18 weeks.Serum TG and TCH, the his-topathological changes, pancreatic malondialdehyde (MDA) content, superoxide dismutase (SOD) ac-tivity and the concentration of free fatty acids in pancreatic tissues were examined.Pancreatic fibrosis was assessed using Sirius Red staining.The expression of desmin, a smooth muscle actin (α-SMA), platelet-derived growth factor receptor type β (PDGFRβ) and transforming growth factor131 (TGFβ1) was determined with immunohistochemistry.Results Pancreatic MDA content, the number of desmin and α-SMA positive cells were significantly increased in all the HFD groups.The FFA content, PDGFRβ, and TGFβ1 in pancreatic tissues increased in rats of 2, 4 and 6 week HFD groups accompa-nied with typical histological alternations including edema, capillary vessels hyperplasia, and focal aci-nar degeneration, vaculation of acinar and islet cells.In 6, 10 and 18 weeks HFD groups, the lesions had progressed and acinar cell atrophy, fatty replacement, deposition of hemosiderin, and interstitial collagen deposition were observed.Conclusions The increased amounts of FFA and lipid peroxidant in pancreatic tissues are associated with pancreatic cell injuryies and synthesis of collagen by activated PSCs during the chronic high-fat diet intake.

Objective: To establish a HPLC method for the determination of liquiritin、 liquiritigenin and iso liquiritigenin in Licorice Mixture.Methods: A Cromasil C 18 column was used. the mobile phase was methanol 0.5% acetic acid for gradient elution. Liquiritin、 liquiritigenin and iso liquiritigenin were determined by dual wavelength, ? 1=276 nm,? 2=372 nm.Results: The linear range of liquiritin was 50.0～1250.0ng, r= 0.9999; The average recovery was 98.30%, RSD =1.01%( n= 6). The linear range of liquiritigenin was 5.0～125.0 ng, r= 0.9998; The average recovery was 98.01%, RSD =0.68%( n= 6). The linear range of iso liquiritigenin was 3.0～6.0 ng, r= 0.9999. The average recovery was 98.37%, RSD= 0.89%( n= 6). Conclusion: This method is convenient, rapid and accurate. It can be used for quality control in production of Licorice Mixture.

Distortion product otoacoustic emission (DPOAE) signal can be used for diagnosis of hearing loss so that it has an important clinical value. Continuously using sweeping primaries to measure DPOAE provides an efficient tool to record DPOAE data rapidly when DPOAE is measured in a large frequency range. In this paper, locally weighted least squares estimation (LWLSE) of 2f1-f2 DPOAE is presented based on least-squares-fit (LSF) algorithm, in which DPOAE is evoked by continuously sweeping tones. In our study, we used a weighted error function as the loss function and the weighting matrixes in the local sense to obtain a smaller estimated variance. Firstly, ordinary least squares estimation of the DPOAE parameters was obtained. Then the error vectors were grouped and the different local weighting matrixes were calculated in each group. And finally, the parameters of the DPOAE signal were estimated based on least squares estimation principle using the local weighting matrixes. The simulation results showed that the estimate variance and fluctuation errors were reduced, so the method estimates DPOAE and stimuli more accurately and stably, which facilitates extraction of clearer DPOAE fine structure.

Objective To explore clinical practice value of Disease Severity Evaluation Scale (DSAS), and divide patient's nursing level according to the results of DSAS. Methods The assessment group was set up for evaluation of the scale, DSAS was used to determine the nursing level of 3 713 hospitalized patients (age > 18 years old) from 17 clinical departments, from April to May 2014. Results Nursing level determined by DSAS was compared with the standard nursing level, kappa coefficient was 0.72, P < 0.05, suggesting that the consistency was better. According to the kappa coefficient, 17 clinical departments could be divided into three categories, namely the applicability of DSAS were different in different departments. Conclusions DSAS can be used as a objective basis for division of nursing level and has a certain clinical significance. But in order to make it guide clinical work better, scoring system with department characteristic should be developed on the basis of DSAS.

80% of low density area in tumor), 10 PR(50%-80%) and 3 NC(0.05). Conclusion For tumor treated with hyperthermia plus radiotherapy, the response evaluation should be based on both the change in the mass size and the percentage of low density area in the tumor.
