AIM: To observe activity of scavenger receptor of macrophage derived from monocytes, the change of inflammation factor in plasma (including CRP, sICAM-1, sVCAM-1) and the influence of atorvastatin on activity of scavenger receptor in patients with coronary heart disease. METHODS: 75 patients with coronary heart disease (CHD), whose plasma lipid levels were normal, were divided into three groups: stable angina pectoris, unstable angina pectoris and acute myocardia infarction. 29 healthy persons were served as control. The level of C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in plasma were determined in all subjects. Monocytes in peripheral blood were dissevered and cultured to transform into macrophage. The influence of atorvastatin on activity of scavenger receptor in macrophage was observed. RESULTS: The level of CRP, sICAM-1, sVCAM-1 and activity of scavenger receptor of macrophage in acute myocardia infarction group were higher than that in stable angina pectoris, unstable angina pectoris and control. Atorvastatin lowered the activity of scavenger receptor of macrophages derived from monocytes in patients with coronary heart disease. Activity of scavenger receptor of macrophages derived from monocytes in patients with coronary heart disease was correlated positively with CRP, sICAM-1 and sVCAM-1. CONCLUSION: Activity of scavenger receptor may be taken as index for monitoring the degree of active vulnerable atherosclerosis plaque. Atorvastatin may inhibit activity of scavenger receptor in macrophages derived from monocytes in patients with coronary heart disease.

Objective To study the relationship between the serum levels of thyroid hormone and the degree of the congestive heart failure as well as the effects of thyroxine on elderly patients with chronic severe congestive heart failure(CHF). Methods 140 cases were divided into group A (60 cases of CHF classes Ⅰ and Ⅱ) and group B (80 cases of CHF classes Ⅲ and Ⅳ) according to the NYHA classification of severity of heart failure. The group B was divided into the observation group (50 cases) and the control group (30 cases) . All patients were treated with conventional methods and thyroxine 20-40 ?g every morning was added in the observation group for 4 weeks. The serum FT 3 ,FT 4 ,TSH,HR,echocardiography and heart function were examined before and after treatment. Results ⑴ Both group A and B had lower base line serum FT 3 and FT 4 ,which were significantly lower in the group B than those in the group A 〔FT 3 : (4.22?0.61) pmol/L vs(3.07?1.10)pmol/L,P

Objective:
To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy.
Methods:
This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer′s protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS.
Results:
There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109).
Conclusion
There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.
