BACKGROUND:Recently, subclinical hypothyroidism has been associated with increased carotid intima-media thickness, but it is controversial. OBJECTIVE:To assess whether carotid intima-media thickness in patients with subclinical hypothyroidism differs from that in euthyroid subjects. METHODS:We searched published studies concerning the carotid intima-media thickness of patients with subclinical hypothyroidism in comparison with euthyroid subjects. Then, we evaluated each potential study for eligibility, assessed the methodological quality, and extracted the data for a Meta-analysis. RESULTS:Eight observational studies with 3 602 cases met the eligibility criteria. In patients with subclinical hypothyroidism, the pooled estimate of the weighted mean difference (WMD) of increased carotid intima-media thickness was 0.056 [95%CI (0.020, 0.092)]. Sensitivity analysis using a pooled result of the seven higher-quality studies demonstrated higher carotid intima-media thickness level in patients with subclinical hypothyroidism than in euthyroid subjects [WMD=0.064, 95%CI(0.024, 0.105)]. In a subgroup analysis, subclinical hypothyroidism was even more significantly associated with the carotid intima-media thickness in patients with a mean thyrotropin level > 10.0 mU/L [WMD=0.082, 95%CI (0.049, 0.116)]. Subclinical hypothyroidism was also associated with a significant increase in systolic blood pressure, triglyceride levels, total cholesterol levels, low-density lipoprotein levels and with a decrease in fasting plasma glucose. This meta-analysis indicates that subclinical hypothyroidism is associated with an increased carotid carotid intima-media thickness, which may be due to elevated thyrotropin, dyslipidemia and hypertension. Despite the obvious individual differences, a prospective large-sample study is necessary to further assess the conclusions of this observation.
2.Essence interpretation and hot debates of American Diabetes Association(ADA)Scientific Sessions in 2020
Chinese Journal of Endocrinology and Metabolism 2021;37(3):180-187
The 80th American Diabetes Association(ADA)Scientific Sessions was held online from June 12 to 16, 2020. There was some hot debates on the topics of diabetes related complications in the annual meeting of ADA. Endocrinologists and cardiologists debated and presented different perspectives. This paper will summarize the debates on the following five topics: (1)Microvascular and macrovascular complications of diabetes are distinct pathophysiologic entities.(2)Guideline recommendations for cardiovascular risk and disease management in type 2 diabetes.(3)Drawing the line between primary and secondary prevention—necessary or too simplistic? (4)Should metformin be considered first-line therapy for individuals with type 2 diabetes with established arteriosclerotic cardiovascular disease(ASCVD)or at high risk for ASCVD? (5)Primary cardiovascular prevention with sodium-glucose co-transporter 2(SGLT2)inhibitors or glucagon-like peptide-1(GLP-1)receptor agonists.

Objective:To establish a method which could quantify human IL-8 mRNA in peripheral blood monocytes.Methods:Two probe were designed aiming at amplicon of RT-PCR,of which one being capture probe adorned 5,end by ammonia and one being monitor probe adorned 3,end by bintony.So as,the capture probe could couple with the N-oxysuccinmide esters(NOS) group on the DNA-binding wells through covalent attachment.In this way,oligonucleotides were immobilized on the plate surface and arise straightly to capture target amplicon.Total RNA was extracted from peripheral blood mononuclear cell and IL-8 mRNA was amplified by using RT-PCR.Heating denatured products and denatured probe,were then added to wells and hybridization occurs between capture probe,target amplicon and detection probe.After the addition of Avidiu-peroxidase developing system,the optical density were read at 450 nm.Results:Sensitivity,detecting PCR product of 16 PCR cycling,of 5?10~3 PBMCs and of a dilute 1∶256 were its prior.Meanwhile,this method could get a specify result and a precise of 5.2%.Conclusion:Resulting in simplicity,sensitivity and specificity results,this method may be a good choice for quantify of PCR products.

Objective To assess the efficacy of Ezscan in evaluating the risk of cardiac autonomic neuropathy (CAN) in diabetes. Methods This study included 144 patients with diabetes. Their serum lipid profile and HbA1c were determined. The heart rate variability was assessed by Holter, and the cardiac autonomic neuropathy by classic experiments. Meanwhile, Ezscan was carried out. Results There was a positive correlation between low frequency (LF) measurements by Holter and Ezscan score( r=0. 39, P<0. 01 ), so did LF/HF and Ezscan score( r=0. 28, P<0. 01 ). Correlations between Ezscan score and other Holter parameters were weaker. There was no correlation between HbA1c and LF measurements. In patients with positive classic experiments, the sensitivity and specificity of Ezscan were 58. 3% and 57.8% respectively. Conclusions Ezscan test is a valuable screening procedure for detecting diabetic complications. It is more facilitative and takes shorter time than does the classical autonomic function assessment.

Objective To study CEAmRNA、CK19mRNA and CK20mRNA in peripheral blood of lung cancer patients by Real-time RT-PCR,consequently discussing those result′s clinical significance.Methods 48 lung cancer patients,8 benign lung disease patients and 30 healthy volunteers of CEAmRNA,CK19mRNA and CK20mRNA in peripheral blood were detectd by Real-time RT-PCR.Results The levels of 48 lung cancer patients CEAmRNA in peripheral blood reach (16 264?28 765) copies/ml,of which 26 patients,results are positive; The levels of 48 lung cancer patients CK19mRNA in peripheral blood reach (14 891?27 244) copies/ml,of which 27 patients,results are positive; The levels of 48 lung cancer patients CK20mRNA in peripheral blood reach (10 924?21 678) copies/ml,of which 20 patients,results are positive. Among of 8 benign lung disease patients,there is just CK20mRNA was detected in one patient,both CEAmRNA and CK19mRNA were not detected in their peripheral blood. As for those 30 healthy volunteers,there is none of the mRNA was detected. Moreover,there is a marked positive correlation between the levels of CEAmRNA,CK19mRNA and CK20mRNA,the levels of CEAmRNA,CK19mRNA and CK20mRNA were correlated to the physiological cause or degree of lung cancer.Conclusion CEAmRNA,CK19mRNA and CK20mRNA in peripheral blood can be as auxiliary index for diagnosing lung cancer micrometastasis,also can monitor the lung cancer micrometastasis by quantity it.

Objective To study the brain protection of sequential double-sided antegrade cerebral perfusion to central nervous system in arotie arch surgery. Methods 24 patients received aortic arch replacement under deep hyperthermic circulatory arrest (DHCA) ,with fight-sided, and following double-sided, and left-sided,if necessary, antagrade cerebral perfnsion through right axillary arterial cannula or right femoral arterial eannula homeochronously. Post-operation recovery and the central nervous complications (CNC) were recorded and analyzed. Results 2 cases died, one of whom died of refractory low cardiac output syndrome and the other died of late massive gastrointestinal tract hemorrhage. No patient suffered severe CNC. Conclusion Sequential double-sided antegrade cerebral perfusion combined with DHCA can provide good brain protection in arotic arch replacement.

2-Dimensional gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry (MALDI-TOF-MS) were used to screen differentially expressed serum proteins in Uyghur patients with hyperuricemia and control subjects.Western blot was used to validate differential proteins.Gel-image analysis revealed that there were 11 differential protein spots.A total of 4 differential protein spots were successfully identified by MALDI-TOF-MS.Complement 3,complement 4,haptoglobin,and apolipoprotein Al levels were up-regulated in patients as compared with controls.The result of complement 3 expression was validated by Western blot,which is accordant with that of proteomics.
