OBJECTIVETo determine the percentage of hypercholesterolemic patients who had met the criteria as total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), defined by the Chinese National Recommendations for Prevention and Treatment of Dyslipidemia.
METHODSAdult patients with hypercholesterolemia, who had been receiving the same lipid-lowering therapy for at least 2 months, were enrolled. Lipid levels were determined at the time of enrollment, to assess whether the patients' lipid levels had reached the criteria for treatment. Patients' cardiovascular risk factors and lipid-lowering treatments were also collected.
RESULTSOne hundred and eighty patients with mean age of 65.8 were studied. Of these, 6.7% had no risk factors and no definite disease of atherosclerosis (low-risk group), 65.5% had risk factors but no documented atherosclerosis (high-risk group), and 27.8% had established atherosclerosis diseases or diabetes mellitus. Overall, only 44% of patients achieved both TC and LDL-C target levels. The success rates were higher among low and high-risk groups than that among patients with atherosclerosis or diabetes mellitus. The relationship between four different lipid-lowering drug therapies and successful patient outcome was also investigated. The success rates were 51.8% for simvastatin, 42.9% for pravastatin, 31.6% for fluvastatin, 12.5% for other drugs respectively.
CONCLUSIONMore than half of the hypercholesterolemic patients receiving lipid-lowering therapy had not achieved TC and LDL-C target levels. Data from this study indicated that a significant gap still existed between dyslipidemia prevention principles and clinical practices, suggesting that more aggressive treatment of dyslipidemia is needed.

Objective To investigate the correlation between single nucleotide polymorphisms (SNPs) of FOXP3 gene and the susceptibility of hepatocellular carcinoma (HCC). Methods Two SNPs rs2280883 and rs3761549 of FOXP3 gene in 392 HCC patients and 372 healthy controls were analyzed by Matrix-Assisted Laser Desorption/ Ionization Time of Flight Mass Spectrometry (MALDI-TOF).Results At rs3761549,C allele frequency was significantly higher ( OR =1.32,95% CI 1.03 -1.70,P =0.027) in HCC patients than healthy controls.Compared with healthy controls,HCC patients had higher frequencies of TT genotype (79.6% ) at rs2280883 or CC genotype (77.6%) at rs3761549 of FOXP3 gene.Patients carrying rs2280883 TT genotype ( OR =1.53,95% CI 1.10 - 2.14,P < 0.00001 ) or rs3761549 CC genotype ( OR =1.92,95% CI 1.39 - 2.64,P < 0.00001 ) were more susceptible to HCC.Stratified analysis showed that rs3761549 CC genotype was significantly associated with higher incidence of portal vein tumor thrombus ( x2 =5.578,P =0.018 ),and rs3761549 TT/CT genotype was significantly associated with higher rate of tumor recurrence in HCC patients (x2 =6.561,P =0.010).Conclusions FOXP3 gene polymorphisms at rs2280883 and rs3761549 might be associated with increased susceptibility to HCC. rs3761549,CC genotype and TT/CT genotype were respectively associated with higher incidence of portal vein tumor thrombus and tumor recurrence in HCC patients.

Objective Doppler ultrasonography was used to screen the incidence of central venous catheter (CVC) thrombosis in severe patients to observe the incidences of catheter-related thrombosis (CRT) at subclavian (SC) and internal jugular (IJ) venous insertion sites, and to analyze the factors affecting the thrombosis. Methods One hundred and twenty three adult patients with IJ or SC CVC admitted to the Department of Intensive Care Unit (ICU) of Zhongnan Hospital of Wuhan University from May to December 2015 were enrolled to be the research objects, they were divided into an IJCVC group (35 cases) and a SCCVC group (88 cases) according to different catheterization sites; they were divided into an operation group (85 cases) and a non-operation group (38 cases) according to whether operation was performed or not; and they were also divided into an anticoagulation group (25 cases) and a non-anticoagulation group (98 cases) according to whether anticoagulation therapy was used or not. Doppler ultrasonography was performed every day to observe the incidences of CRT during ICU stay. Results One hundred and twenty-three patients were included in this study. CRT was detected in 11 (8.9%) patients, with an incidence of 22.1 per 1 000 catheter-days. All the 11 cases with CRT were presented within 3 days after the insertion, with 9 cases (81.8%) on the first day and 2 cases (18.2%) on the third day. The incidence of CRT in SCCVC group was significantly lower than that in IJCVC group [5.7% (5/88) vs. 17.1% (6/35), P < 0.05], with the rates of 12.6 and 59.4 per 1 000 catheter-days, respectively. There were no statistical significant differences in the incidences of CRT between operation group and non-operation group [11.8% (10/85) vs. 2.6% (1/38)], and between anticoagulation group and non-anticoagulation group [8.0% (1/25) vs. 9.2% (2/98), both P > 0.05]. Conclusions The incidence of CRT at IJCVC site is estimated to be 3-times higher than that at SCCVC site, anticoagulants or surgical operation may have impacts on the incidence of CRT, although there were no statistically significant differences. The CRT usually occurs within 3 days after the catheter insertion. Frequent bedside ultrasonography in the first 3 days after catheterization can confirm the diagnosis and guide clinical treatment.

Objectives:
. The necessity to develop a method for prognostication and to identify novel biomarkers for personalized medicine in patients with head and neck squamous cell carcinoma (HNSCC) cannot be overstated. Recently, pathomics, which relies on quantitative analysis of medical imaging, has come to the forefront. CXCL8, an essential inflammatory cytokine, has been shown to correlate with overall survival (OS). This study examined the relationship between CXCL8 mRNA expression and pathomics features and aimed to explore the biological underpinnings of CXCL8.
Methods:
. Clinical information and transcripts per million mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA)-HNSCC dataset. We identified correlations between CXCL8 mRNA expression and patient survival rates using a Kaplan-Meier survival curve. A retrospective analysis of 313 samples diagnosed with HNSCC in the TCGA database was conducted. Pathomics features were extracted from hematoxylin and eosin–stained images, and then the minimum redundancy maximum relevance, with recursive feature elimination (mRMR-RFE) method was applied, followed by screening with the logistic regression algorithm.
Results:
. Kaplan-Meier curves indicated that high expression of CXCL8 was significantly associated with decreased OS. The logistic regression pathomics model incorporated 16 radiomics features identified by the mRMR-RFE method in the training set and demonstrated strong performance in the testing set. Calibration plots showed that the probability of high gene expression predicted by the pathomics model was in good agreement with actual observations, suggesting the model’s high clinical applicability.
Conclusion
. The pathomics model of CXCL8 mRNA expression serves as an effective tool for predicting prognosis in patients with HNSCC and can aid in clinical decision-making. Elevated levels of CXCL8 expression may lead to reduced DNA damage and are associated with a pro-inflammatory tumor microenvironment, offering a potential therapeutic target.

OBJECTIVE:
To explore the effective treatment regimen for osteoradionecrosis of temporal bone.
METHOD:
Twenty-seven patients with massive osteoradionecrosis in temporal bone were included and retrospectively analyzed, in which, 15 cases received surgery and the other 12 cases adopted non-surgical treatment.
RESULT:
In the surgery group, three cases died one year postoperatively and died of massive hemorrhage due to internal carotid blowout. One case died four years after surgery without clear cause of death, and two cases were lost to follow up. Out of the nine survivors, the follow up period ranged from four months to eight years (one was followed up eight years, one was followed up over four years, four were followed up two-three years, one was followed up over one year, one was followed up nine months, and one was followed up four months, respectively). Patients classified as the type III received best outcome, and patients of type V and IV without invasion of the internal carotid artery received good surgical effects, while patients classified as the type IV with internal carotid artery invasion presented low survival rate. Two cases in the non-surgical group died of internal carotid rupture, and the other ten cases presented with repeated infection and expansion of the osteoradionecrosis lesion.
CONCLUSION
The new classification criteria is helpful in diagnosis of location of lesions,and can serve as a guide for clinical therapy. Massive osteoradionecrosis in temporal bone responded unfavorably to conservative treatment, compared to that, surgery can effectively control the expansion of the lesion and markedly improve patient quality of life. Long-term follow up is necessary because of the slow development of osteoradionecrosis after surgery.
