Objective To explore effects of apoAI on MCP?1 levels in the plasma and the Ly6Chi monocyte proportion in the blood and spleen of atherosclerotic mice,as well as on CCR2 expression in vitro. Methods Sixteen male apoE?/?mice were fed with high cholesterol diet for 12 weeks. Mice were randomly divided into control and apoAI groups and were administered with PBS or apoAI(40 mg/kg),respectively,via tail vein on the 1st and 3rd day before sacrifice. Mice in both groups were administered LPS(25μg/mouse)via intraperitoneal injection 12 h before sacrifice. Plas?ma levels of MCP?1 were determined using ELISA,and the Ly6Chi monocyte proportion was analyzed using flow cytometry. In addition,human monocytic THP?1 cells were randomly divided into control and apoAI(10 mg/L)?treated groups,pretreated with corresponding intervention,and incubated with LPS(10μg/L). CCR2 expression levels were measured by Western blotting. Results Compared with the control treatment, apoAI treatment remarkably reduced MCP?1 levels in plasma and Ly6Chi monocyte proportion in the blood and spleen(P<0.01). Furthermore, apoAI treatment inhibited CCR2 expression in monocytes in vitro(P<0.05). Conclusion apoAI can reduce MCP?1 levels in plasma and the Ly6Chi monocyte proportion in the blood and spleen and can inhibit CCR2 expression in monocytes in vitro.

OBJECTIVE To explore the effect of aqueous extract of Zheng Chaihu Yin(ZCH)on paracetamol(acetaminophen,APAP)-induced hepatotoxicity. METHODS Male ICR mice were divided into three scenarios randomly:the single treatment dose of ZCH,multiple treatment or pretreatment dose of ZCH. Each scenario had a up control group and an APAP model group,while single treatment dose of ZCH group had a ZCH group at the same time. The dose of APAP and ZCH was 500 mg·kg-1 and 36 g · kg- 1,respectively. 24 h after the last administration,plasma and liver samples were prepared. Ultra- performance liquid chromatography/quadrupole- time- of- flight mass spectrometry (UPLC-Q-TOF-MS)based metabolomics profiling was used to examine changes in plasma after expo?sure to ZCH,APAP or co-exposure to ZCH and APAP. Glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminas (GOT) values were determined by a biochemical auto analyzer in plasma. Histopathologic changes in the liver were observed and the area was calculated after HE staining. The data were analyzed with SPSS16.0 statistical software and the results were compared with the test between the two groups to find biomarkers. Also,SIMCA software was used for partial least squares-discriminant analysis (PLS-DA) pattern recognition. RESULTS Compared to control group, APAP dosing alone caused an increase in plasma transaminases and alterations in multiple metabolic pathways. Compared to APAP group,decrease in plasma transaminases was noted when ZCH was administered after or prior to APAP. Histopathologic results showed that in the single treatment group, multiple treatment group and pretreatment group,ZCH could alleviate the liver damage induced by APAP from (32.3 ± 12.0)% to (14.2 ± 9.9)%,(8.6 ± 7.9)% to (5.2 ± 1.7)% and (32.5 ± 10.0)% to (5.2 ± 6.4)%(P<0.05). Similarly,the PLS-DA of the LC-MS data showed that the groups dosed with APAP alone were the most distinct from controls,while animals dosed with ZCH prior to or after APAP treatment were located near control group. Metabolic spectrum results showed that ZCH could restore the changes in endogenous substances including lipid metabolism,amino acid metabolism,sugar metabolism and energy metabolism induced by APAP to normal. CONCLUSION ZCH water-extraction plays major roles in the regulation of metabolism on APAP-induced liver injury. These studies demonstrate that UPLC-Q-TOF-MS-based metabolomic analysis can be sensitively and accurately predict the initiation and progres?sion of liver injury and greatly contribute to a better understanding of the hepatoprotective effects of ZCH in a clinical environment.

Objective To evaluate the efficacy and safety of the unilateral and bilateral drainage in hilar malignant biliary obstruction with a meta?analysis of relevant studies. Methods A systematic electronic search with keywords “ biliary stent”, “hilar tumor” and “malignant biliary obstruction” was independently performed by two reviewers in major electronic databases of Pubmed, EMBASE, Cochrane Library and Web of Science. A meta?analysis was conducted using Revman 5?? 1 software. Results Six studies were included with a total number of 558 patients, of whom 307 patients underwent unilateral biliary drainage and 251 pa?tients bilateral drainage. There was no significant difference in early complications ( OR = 1?? 03,95% CI:0?? 58?1?? 81,P = 0?? 93), later complications (OR = 0?? 98,95%CI:0?? 46?2?? 07,P = 0?? 95), operation success rate (OR= 1?? 42,95%CI:0?? 76?2?? 66,P = 0?? 28),drainage efficacy or median survival time between the two groups. Compared with unilateral biliary drainage, bilateral biliary drainage had a longer time of stent patency (MD = - 29?? 12,95% CI:- 38?? 55?- 19?? 70,P< 0?? 001). Conclusion Both unilateral and bilateral biliary drainage are safe and effective for hilar malignant biliary obstruction, but more high quality clinical researches are needed.

Chinese Journal of Postgraduates of Medicine 2020;43(8):745-749
Objective:To detect the methylation status of sine oculis homeobox homolog 1 (Six1) in breast cancer and study its value in disease condition and prognosis evaluation.Methods:Methylation specific polymerase chain reaction (PCR) was used to detect the Six1 gene methylation in 80 patient with breast cancer (breast cancer group) and 50 patients with benign breast disease(benign breast disease group) in Binzhu Center Hospital from January 2015 to January 2017. The Six1 gene methylation rates in different clinicopathological factors were compared. Comparison of unmethylated and methylated Six1 gene in quality of life were made in breast cancer patients.Results:The unmethylation rate and mRNA expression of Six1 gene in breast cancer group were significantly higher than those in benign group ( P<0.05). Six1 genes in HCC1937, MCF-7, Hs 578T and Bcap-37 breast cancer cells were unmethylated. The unmethylated rate of Six1 gene were significantly higher in patients with Karnofsky score <70 scores, poorly differentiation, tumor maximum diameter ≥ 5 cm, number of lymph node metastases ≥ 9, with distant metastasis and TNM stage Ⅲ+Ⅳ class, compared with those in patients with Karnofsky score ≥ 70 scores, high and medium differentiation, maximum tumor diameter <5 cm, number of lymph node metastases<9, no distant metastases, and TNM stage Ⅰ+Ⅱ class. The patients with Six1 gene unmethylated had significantly lower quality of life compared with patients with Six1 gene methylated ( P<0.05). Conclusions:Six1 gene is hypomethylated in breast cancer and plays an important role in the evaluation of breast cancer disease condition and prognosis.
