Objective To evaluate the clinical value and toxicities of docetaxel plus capecitabine in the first-line treatment of metastatic breast cancer (MBC),and compare the outcomes among different molecular subtypes.Methods A total of 108 patients with MBC who received docetaxel plus capecitabine combination treatment between January 1,2012 and December 31,2015 in Bejing Chaoyang District Sanhuan Cancer Hospital were retrospectively analyzed,and 104 cases were available for evaluation.The clinicopathological characteristics,clinical value and toxicities of these patients were evaluated.Results The patients were divided into 3 molecular subtypes,among 104 patients,85 patients in Luminal subtype,14 patients in triple negative breast cancer (TNBC) subtype,and 5 patients in human epidermal growth factor receptor-2 (HER-2) over expression subtype.The treatment achieved objective responses (OR) in 55 patients (52.9％),and the disease control rate (DCR) was 88.5％,including complete response (CR) in 4 patients,partial response (PR) in 51 patients,stable disease (SD) in 37 patients,and progressive disease (PD) in 12 patients.In Luminal subtype,4 patients achieved CR,43 PR,33 SD,and 5 PD.In TNBC subtype,6 patients achieved PR,3 SD,5 PD.In the HER-2 over expression subtype,2 patients achieved PR,1 SD,2 PD.There was no significant difference in the short-term therapeutic effect among 3 molecular subtypes (x2 =4.429,P =0.106).As a result,the progression-free survival (PFS) of the 104 patients was 1.5-121.0 months,and the median PFS was 10.0 months.The median PFS was 11.0 months in Luminal subtype,4.0 months in TNBC subtype and 10.3 months in HER-2 over expression subtype,with a significant difference (x2 =7.510,P =0.006).The most common adverse events were hand-foot syndrome (HFS),nausea or vomiting,neutropenia,anaemia,diarrhea and so on.The incidence of grade 2/3 HFS was 44.2％ (46/104),and the grade 3/4 neutropenia was 39.4％ (41/104).Conclusion The first-line treatment of MBC using docetaxel plus capecitabine is effective,and the toxicities can be tolerable,especially in the Luminal subtype.

11.1 mmol/L were treated by 2 weeks CSII.An intravenous glucose tolerance test(IVGTT) was performed before and after CSII.The levels of fasting plasma glucose(FPG),2 hours postprandial glucose(2hPG),glycosylated hemoglobin A1c(HbA1c),first-phase secretion of insulin,the mean area under the curve(AUC) of insulin,insulin sensitivity index(ISI),insulin resistance index(Homa IR) and insulin secretion index(Homa ?) were compared.Results The excellent control of FPG and 2hPG in 20 out of 21 patients were achieved stably in 2.8?1.6 days and 7.8?1.9 days by CSII.After the treatment,FPG,2h PG and HbA1c were significantly decreased(P

Objective:To observe the short-term efficacy and safety of apatinib in combination with dose-dense paclitaxel and carboplatin in locally advanced triple-negative breast cancer (TNBC) patients.Methods:From September 2018 to September 2019, 17 stage Ⅱ/Ⅲ TNBC patients were enrolled in this single arm, single center prospective phase Ⅱ study. They received neoadjuvant treatment of apatinib 250 mg per day, paclitaxel 175 mg/m 2 on 1 st day and a dose of carboplatin according to the area under curve (AUC)=4 on 2 nd day, every 14 days as a cycle. Results:By January 2020, 16 cases completed 4-7 cycles of apatinib treatment and 4-8 cycles of chemotherapy. The median cycles of apatinib treatment and chemotherapy were 5 cycles and 6 cycles, respectively. Two cases achieved complete responses (CR), 12 achieved partial responses (PR), 2 achieved stable diseases (SD) and no progressive disease was observed. The objective response rate (ORR) was 87.5%, disease control rate (DCR) was 100%. By January 2020, among 12 patients who received surgery, 8 achieved pathologic complete response (pCR, 66.7%). The grade Ⅲ/Ⅳ adverse events included: neutropenia, thrombocytopenia in 3 cases (18.8%) each, anemia, fatigue, arrhythmia and alanine aminotransferase (ALT) elevation in 1 case each. Apatinib was interrupted in 5 cases, and was discontinued in 3 cases; chemotherapy dosage was reduced in 1 case.Conclusion:Apatinib in combination with dose-dense paclitaxel and carboplatin neoadjuvant therapy are effective and well tolerated in locally advanced TNBC patients.

Antibiotics are widely used and prevalently distributed in the environment. The issue of antibiotic resistance genes has posed a huge threat to the global public health. Soil is an important sink of antibiotics in the environment. Antibiotic exposure may introduce adverse effects on soil organisms, and bring indirect but potential risks to human health. Therefore, it is urgent to take actions to remediate antibiotics-contaminated soil. This review summarized effects of antibiotics on phenotype growth of plants, physiological characteristics and community structure of animals, composition and structure of microbial communities, and transmission of antibiotic resistance genes among organisms in soil. Additionally, the potential and prospects of employing antibiotic-resistant soil plants, animals, microorganisms, and their combinations to treat antibiotics-contaminated soil were illustrated. Last but not least, the unaddressed issues in this area were proposed, which may provide insights into relevant research directions in the future.
