Objective:To explore clinical application value of color Doppler ultrasound (CDU) assigned to diagnose triple-negative breast cancer (TNBC) and axillary lymph node metastasis (ALNM).Methods:A retrospectively analyzed of proved of clinical data on the 863 patients breast cancer in women by CDU inspection,operation and pathology.According results will be divided into TNBC group and non negative breast cancer (NTNBC) group via clinical pathological and immunohistochemical detection.Using multi-factor unconditioned Logistic regression analysis the CDU supposed the diagnosis and the correlation of TNBC.Results:The coincidence rate of CDU and pathological diagnosis was 90.96％ (785/863),78 cases (9.04％) remove breast masses,105 patients TNBC group and NTNBC group 680 patients.The mass circular or elliptic (48.57％ vsl0.70 ％),the tumor maximum diameter 5.0 cm (21.90％ vs 15.30 ％),micro calcifications (87.62％ vs 74.12 ％),state clearly (56.19％ vs 41.47 ％),no burr edge character (74.29％ vs 41.62 ％),peripheral hyperechoic halo ring (74.29％ vs46.76 ％),rear echo attenuation (72.38％ vs 46.76 ％),no ALNM (61.90％ vs 37.35％) comparing the two groups exists significant difference (P＜ 0.05),while the mass number,and vertical and horizontal diameter ratio,degree of echo,echo distribution and blood flow classification comparing the two groups were no significant difference (P＞ 0.05).The CDU fu points ＞ 10 divided into NTNBC and pathological coincidence rate 93.93％ (680/724),8 ～ 10 points TNBC suspected diagnosis coincidence rate 11.51％ (16/139),＜ 8 points TNBC tendency diagnosis coincidence rate 64.03％ (89/139),TNBC total diagnostic coincidence rate was 75.54％ (105/139).In CDU diagnosed 785 cases of breast cancer,the ALN enlargement in 319 cases (40.64％),with TNBC group was 61.90％ (65/105),NTNBC group was 37.35％ (254/680).Logistic regression analysis results:tumor assumes the circular or elliptic,edge without burr,peripheral hyperechoic halo ring,rear echo attenuation and ALNM with TNBC has certain correlation (P＜0.05).Conclusion:The seemingly benign breast diseases and axillary lymph node enlargement,the CDU,supposed less than 8 points,age 50 or less or not at the same time,menopause or having a history of breast cancer susceptibility to family,important reference index,clinical value has high of CDU diagnostic of TNBC and ALNM.

OBJECTIVES: To explore the metabolite characteristics in medial prefrontal cortex (mPFC) by METHODS: A total of 46 patients with the first-episode schizophrenia (FES), 49 people with clinical high risk (CHR), 61 people with genetic high risk (GHR), and 58 healthy controls (HC) were enrolled. The levels of N-acetylaspartylglutamate+N-acetylaspartate (tNAA), choline-containing compounds (Cho) and myo-inositol (MI), glutamate+glutamine (Glx) in medial prefrontal cortex were measured by single-voxel RESULTS: There were significant differences in Glx, tNAA, and MI concentrations among 4 groups (all CONCLUSIONS The decreased levels of MI and Glx in the FES patients suggest that there may be glial functional damage and glutamatergic transmitter dysfunction in the early stage of the disease. The compensatory increase of metabolites may be a protective factor for schizophrenia in the genetic individuals.

The syndrome of dampness stagnancy due to spleen deficiency (DSSD) is relatively common globally. Although the pathogenesis of DSSD remains unclear, evidence has suggested that the gut microbiota might play a significant role. Radix Astragali, used as both medicine and food, exerts the effects of tonifying spleen and qi. Astragalus polysaccharide (APS) comprises a macromolecule substance extracted from the dried root of Radix Astragali, which has many pharmacological functions. However, whether APS mitigates the immune disorders underlying the DSSD syndrome via regulating gut microbiota and the relevant mechanism remains unknown. Here, we used DSSD rats induced by high-fat and low-protein (HFLP) diet plus exhaustive swimming, and found that APS of moderate molecular weight increased the body weight gain and immune organ indexes, decreased the levels of interleukin-1β (IL-1β), IL-6, and endotoxin, and suppressed the Toll-like receptor 4/nuclear factor-‍κB (TLR4/NF-‍κB) pathway. Moreover, a total of 27 critical genera were significantly enriched according to the linear discriminant analysis effect size (LEfSe). APS increased the diversity of the gut microbiota and changed its composition, such as reducing the relative abundance of Pseudoflavonifractor and Paraprevotella, and increasing that of Parasutterella, Parabacteroides, Clostridium XIVb, Oscillibacter, Butyricicoccus, and Dorea. APS also elevated the contents of short-chain fatty acids (SCFAs). Furthermore, the correlation analysis indicated that 12 critical bacteria were related to the body weight gain and immune organ indexes. In general, our study demonstrated that APS ameliorated the immune disorders in DSSD rats via modulating their gut microbiota, especially for some bacteria involving immune and inflammatory response and SCFA production, as well as the TLR4/NF-κB pathway. This study provides an insight into the function of APS as a unique potential prebiotic through exerting systemic activities in treating DSSD.
