ABSTRACT

Background@#Xylazole (Xyl) is a veterinary anesthetic that is structurally and functionally similar to xylazine. However, the effects of Xyl in vitro remain unknown. @*Objectives@#This study aimed to investigate the anesthetic mechanism of Xyl using fetal rat nerve cells treated with Xyl. @*Methods@#Fetal rat nerve cells cultured for seven days were treated with 10, 20, 30, and 40 μg/ mL Xyl for 0, 5, 10, 15, 20, 25, 30, 45, 60, 90, and 120 min. Variations of amino acid neurotransmitters (AANTs), Nitric oxide-Cyclic GMP (NO-cGMP) signaling pathway, and ATPase were evaluated. @*Results@#Xyl decreased the levels of cGMP and NO in nerve cells. Furthermore, Xyl affected the AANT content and Na+ -K+ -ATPase and Ca2+ -Mg2+ -ATPase activity in nerve cells. These findings suggested that Xyl inhibited the NO-cGMP signaling pathway in nerve cells in vitro. @*Conclusions@#This study provided new evidence that the anesthetic and analgesic effects of Xyl are related to the inhibition of the NO-cGMP signaling pathway.

ABSTRACT

OBJECTIVE:To inv estigate the effects of 4-hydroxy-2(3H)-benzoxazolone on inflammatory and apoptosis signaling pathways in non-alcoholic fatty liver disease (NAFLD)model rats. METHODS :SD rats were divided into normal control group(10 rats)and modeling group (50 rats). Normal control group was given basic diet ,and modeling group were given high-fat diet to induce NAFLD model. After modeling ,the rats were divided into normal control group ,model group ,silibinin group (26.25 mg/kg),and 4-hydroxy-2(3H)-benzoxazolone high-dose ,medium-dose and low-dose groups (100,50,25 mg/kg),with 8 rats in each group. Normal control group and modeling group were given 0.6% CMC-Na intragastrically ,and other groups were given relevant medicine 10 mL/kg intragastrically ,once a day ,for consecutive 4 weeks. After last medication ,the serum levels of albumin(ALB),total protein (TP),globulin(GLB),ALB/GLB and free fatty acid (FFA)were detected ;TUNEL staining was used to observe the apoptosis of rat hepatocytes. Western blot assay was used to detect the protein expression and phosphorylation level of inflammatory signaling pathway related proteins [Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MyD88), nuclear factor-κB p65(NF-κB p65),NF-κB inhibitor protein(IκBα)] in liver tissue as well as the expression of apoptosis signaling pathway related proteins [B cell lymphoma 2(Bcl-2),Bax,caspase-3]. RESULTS :Compared with model group ,serum levels of TP (except for low-dose group ),GLB and FFA ,the protein expression of TLR 4(except for low-dose group ),MyD88 (except for medium-dose group )and caspase- 3,the phosphorylation levels of NF-κB p65 and IκBα protein were decreased significantly(P<0.05 or P<0.01). The ratio of A LB/GLB in serum and the ratio of Bcl- 2/Bax in liver tissue were significantly increased(P<0.05 or P<0.01),and the phenomenon of hepatocyte apoptosis was improved. CONCLUSIONS :4-hydroxy-2 (3H)-benzoxazolone can ameliorate NAFLD in rats ,and the mechanism may be associated with inhibiting the expression TLR 4/ MyD88/NF-κB signaling pathway-related proteins and apoptosis-related proteins in liver tissues.

ABSTRACT

Objective@#To analyze the possible responses of parents of young children to Child sexual assault (CSA) and the potential influencing factors, so as to provide evidence for prevention programs of CSA.@*Methods@#Part of the data from "2016-2020 Child Injury Prevention Project" was used to analyze responses to CSA among parents of children younger than 3rd grade in primary school by chi square test and Logistic regression analysis.@*Results@#A total of 4 072 parents were included in the analysis. Among them, 86.8% of parents chose "to solve problems together", 51.0% of parents taking children to a "psychologist", 4.9% of parents "scolding children for being too careless", 2.9% of parents "letting child not disclose abuse" and 6.5% of parents chose "other" coping methods. Parents with foreign nationality [OR(95%CI)=2.58(1.25-5.15)] and lower education level (OR=0.26-0.64) tend to "blame" their children. Mothers [(OR(95%CI)=0.54(0.33-0.90)], higher parental education level (OR=0.27-0.72) were more reluctant to encourage their children to keep quiet. Mothers [OR(95%CI)=1.73(1.32-2.27)], older children (OR=1.33-1.78) and parents with higher education level (OR=1.65-2.99) tend to "accompany". Parents aged 30 or more, and from high school/technical school/technical secondary school tend to take their children to see a "psychologist" [OR(95%CI)=1.39(1.14-1.71), 1.79(1.26-2.53)].@*Conclusion@#Parents universally pay attention to the physical and mental health of children after CSA, but some parents still take negative coping methods, e.g. "blame" and "not disclose". Parenting educational level, duration of parent-child communication and age of children are primary factors associated with parental responses to child sexual assault. This study suggests that prevention secondary injury following child sexual assault should be farther strengthened, while fully considering the characteristics of the educated objects.

ABSTRACT

@#Objective    To compare the short-term and long-term effects of minimally invasive esophagectomy (MIE) and traditional open esophagectomy (OE) in patients with stage T1b esophageal squamous cell carcinoma (ESCC). Methods    We retrospectively analyzed the clinical pathology data of 162 patients undergoing thoracic surgery at Northern Jiangsu People's Hospital from 2015 to 2018 whose pathological diagnosis was stage pT1b ESCC. According to the surgical approach, they were divided into MIE group and OE group. There were 55 males and 21 females in the OE group, with an average age of 63.3±5.6 years, and 60 males and 26 females in the MIE group, with an average age of 64.7±6.1 years. The preoperative, intraoperative and postoperative data of the two groups were compared and followed up. Survival data were compared using Kaplan-Meier and log-rank tests between the two groups, and Cox proportional hazard regression models were used to analyze prognostic factors. Results    Compared with the OE group, the intraoperative bleeding volume of the MIE group was less (119.8±70.0 mL vs. 210.5±136.2 mL, P<0.001), and the lymph nodes dissected during the operation were more (19.1±7.4 vs. 13.8±5.9, P<0.001), the rate of postoperative pulmonary infections was lower (9.3% vs. 21.1%, P=0.036), but the operation time was longer (240.0±52.4 min vs. 179.5±35.7 min, P<0.001). Twenty-one patients had lymph node metastasis, and the lymph node metastasis rate was 13.0%. At the end of the follow-up, 19 patients died, and the overall survival (OS) at 1 year, 3 years, and 5 years after operation were 97.5%, 88.8% and 82.9%, respectively; 31 patients had recurrence and metastasis, and the disease-free survival (DFS) rate at 1 year, 3 years, and 5 years after operation was 95.1%, 80.9% and 75.6%. There was no significant difference in OS and DFS between the two groups. Multivariate Cox regression analysis of OS found that lymph node metastasis, anastomotic fistula and chylothorax were independent risk factors for OS. Multivariate Cox regression analysis of DFS found that lymph node metastasis, anastomotic fistula, chylothorax, and vascular cancer thrombus were independent risk factors for OS. Conclusion    MIE can achieve the same long-term effects as OE, with less intraoperative bleeding, more lymph nodes dissected, and lower incidence of postoperative pulmonary infections, but it takes longer operation time.

ABSTRACT

OBJECTIVE@#To explore the value of PCR-flow fluorenscence immunmicrobeads assay in prenatal gene diagnosis of thalassemia.@*METHODS@#A total of 1001 pregnant women and their couples checked in the First Affiliated Hospital of Sun Yat-Sen University from January 2016 to August 2019 were selected. Both pregnant women and their spouses were the carriers of thalassemia gene. Samples such as amniotic fluid, were used to extract genomic DNA at the right time. Parallel detection of α- and β- thalassemia genes to samples should be carried out by PCR-flow cytometric fluorescence hybridization and traditional multiple Gap-PCR and PCR-RDB techniques. The consistency of two methods in gene diagnosis of thalassemia was evaluated by analyzing the results of detection.@*RESULTS@#389 normal genotypes (38.86%, 389/1001) and 59 abnormal genotypes (61.14%, 612/1001) was cheked out by the two methods, including 416 cases of α-thalassemia, 162 cases of β-thalassemia and 34 cases of αβ- complex thalassemia. The main genotypes of α-thalassemia were --@*CONCLUSION@#Guangzhou is a area with high incidence of thalassemia, and the genetic types of thalassemia are complex and diverse. Prenatal diagnosis is the final barrier to the prevention of thalassemia. PCR flow-cytometric fluorescence hybridization, as a simple and fast technique, combined with traditional techniques in parallel contributed to the accuracy of prenatal gene diagnosis of thalassemia.

ABSTRACT

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disease worldwide. Current guidelines of IBS are mostly based on the western populations and expected to vary in different communities. China has a large population and a vast literature is available on IBS. Due to linguistic variations in the literature, the studies are not widely known and their conclusions thus remain largely obscured to the western medical literature. In this article, we reviewed the published literatures on the investigations of IBS epidemiology, diagnosis, and management in the Chinese population and emphasized the different findings gleaned from the western publications. The detailed literature review will benefit understanding of and promote future study on IBS.

ABSTRACT

BACKGROUND@#Obesity is a fundamental factor in metabolic disorders such as hyperlipidemia, insulin resistance, fatty liver, and atherosclerosis. However, effective preventive measures are still lacking. This study aimed to investigate different surgical protocols for removing partial adipose tissue before the onset of obesity and determine whether, and by which protocol, preliminary adipose removal could exert potent preventive effects against diet-induced metabolic disorders.@*METHODS@#Male low-density lipoprotein receptor (LDL-R) knockout (KO) mice were randomly divided into four groups and subjected to epididymal fat removal (Epi-FR) surgery, subcutaneous fat removal (suQ-FR) surgery, both subcutaneous and epididymal fat removal (Epi + suQ-FR) surgery, or sham-operation. After 1 week of recovery, all mice were given a high-fat diet (HFD) for 10 weeks to induce metabolic disorders.@*RESULTS@#In the Epi-FR group and the sham-operated group, the mean numbers of the residual subcutaneous fat were 28.59 mg/g and 18.56 mg/g, respectively. The expression of relative genes such as Pparg, Cebpa, Dgat2, Fabp4 and Cd36 in the residual subcutaneous fat increased 2.62, 3.90, 3.11, 2.06, 1.78 times in the Epi-FR group compared with that in the sham-operated group. Whereas in the other fat-removal groups, the residual fat depots had no significant change in either size or gene expression, as compared with those of the sham-operated group. Plasma lipid and glucose levels and insulin sensitivity, as detected by the glucose tolerance test, were not significantly alleviated in the three fat removal groups. Liver mass or lipid content was not attenuated in any of the three fat removal groups. The atherosclerosis burdens in the entire inner aorta and aortic root did not decrease in any of the three fat removal groups.@*CONCLUSIONS@#Our data suggest that removal of epididymal adipose or subcutaneous adipose alone or in combination before the onset of obesity did not protect against hyperlipidemia, insulin resistance, fatty liver, or atherosclerosis in LDL-R KO mice fed with a HFD. Hence, adipose removal possibly does not represent a potential approach in preventing obesity-related metabolic disorders in the obesity-susceptible population.

ABSTRACT

A patient was pregnant four months after the percutaneous coronary intervention, and the ultrasound indicated a complete placenta previa and a placenta percreta. Concerned about radiation and drugs exposure on the fetus, the patient chose to terminate the pregnancy. After multidisciplinary consultation, tirofiban was used for antithrombotic therapy in substitution for dual antiplatelet drugs, and an abdominal aortic balloon was inserted preoperatively. The placenta that penetrated the serous membrane and uterine wall at laparotomy was resected, and the uterus was reconstructed. Prophylactic antibiotics, anticoagulation, and transitional antiplatelet therapy with tirofiban were given after the operation. The patient was discharged on day six postoperatively.

ABSTRACT

Objective:To evaluate the value of 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)-fibroblast activating protein inhibitor (FAPI)-04 PET/CT on assessing different pathological grades in patients with renal fibrosis. Methods:A total of 25 patients (11 males, 14 females; age (39.3±13.9) years) diagnosed with renal fibrosis in the Affiliated Hospital of Southwest Medical University from September 2020 to August 2021 were retrospectively analyzed. All patients underwent renal puncture examination and 68Ga-DOTA-FAPI-04 PET/CT examination. The pathological results of kidney puncture were as the " gold standard" to divide the patients into mild fibrosis (Ⅰ), moderate fibrosis (Ⅱ), and severe fibrosis (Ⅲ). At the same time, 20 patients (10 males, 10 females; age (47.5±13.2) years) who underwent 68Ga-DOTA-FAPI-04 PET/CT examination showed no abnormal uptake of radioactivity in bilateral kidneys and no history of urinary system related diseases were enrolled as normal controls. Parameters including the maximum standardized uptake value (SUV max) of both kidneys, the mean standardized uptake value (SUV mean) of the liver, target/background ratio (TBR), glomerular filtration rate (GFR), and serum creatinine (Scr) were collected. Kruskal-Wallis rank sum test and Bonferroni correction method were used to compare the differences of SUV max, SUV mean, TBR and Scr among groups. One-way analysis of variance and least significant difference (LSD) t test were used to compare the difference of GFR among groups. The receiver operating characteristic (ROC) curve analysis was used to analyze the diagnostic efficacy of SUV max for the degree of renal fibrosis. Results:Of 25 patients, 22 had increased imaging agent uptake and the sensitivity of 68Ga-DOTA-FAPI-04 PET/CT in diagnosing renal fibrosis was 88%. The SUV max and TBR of patients with fibrosis grade Ⅰ, Ⅱ and Ⅲ were significantly higher than those of controls (SUV max: 4.40(3.30, 4.50), 5.90(4.28, 6.48), 8.50(7.50, 9.73) and 1.44(1.38, 1.68); TBR: 6.340±2.389, 8.097±1.420, 11.343±2.002 and 2.986±0.645; H values: 33.685, 32.368, all adjusted P<0.05 (Bonferroni correction method)). The Scr of patients with fibrosis grade Ⅰ and Ⅲ were significantly different (70.1(55.4, 92.5) and 174.1(161.4, 498.2) μmol/L; H=9.770, adjusted P<0.05 (Bonferroni correction method)). The liver SUV mean of patients with renal fibrosis grades Ⅱ and Ⅲ were significantly higher than that of controls (0.673±0.129, 0.751±0.170 and 0.514±0.142; H=15.609, both adjusted P<0.05 (Bonferroni correction method)). The GFR of patients with fibrosis grade Ⅲ had significant differences with grade Ⅰ and Ⅱ ((27.867±15.747), (87.756±31.657) and (63.160±29.556) ml/min; F=8.298, both P<0.05). ROC curve analysis showed that the area under curve was 0.946 7 (95% CI: 0.899 6-0.993 8, P<0.001). Conclusion:68Ga-DOTA-FAPI-04 PET/CT has a certain value in evaluating the degree of renal fibrosis, which can be used as a supplementary examination method for diagnosing renal fibrosis.

ABSTRACT

Objective:To observe the pattern change of chemokine (C-X-C motif) ligand 12 (CXCL12)/C-X-C chemokine receptor type 4 (CXCR4) in systemic lupus erythematosus (SLE) by comparing the condition of SLE patients between pre-treatment and post-treatment.Methods:Peripheral blood mononuclear cells were obtained from 15 healthy controls and 8 first visit SLE patients before and after treatment. The expression of CXCR4, CD3, and CD19 on lymphocytes were detected by flow cytometry. CXCL12 concentration in serum was measured by enzyme-linked immunosorbent assay. For statistical analysis, the independent sample t test was used for independent samples of normally distributed data, the paired sample t test was used for paired samples of normally distributed data, the Mann-Whitney U test was used for independent samples of nonnormal distribution data, and the Wilcoxon test was used for comparison of related samples of non-normal distribution data. In the correlation analysis, Pearson correlation coefficient was used for data conforming to the normal distribution, and Spearman correlation coefficient was used for data not conforming to the normal distribution. Results:① The percentage of CXCR4 + lymphocyte subsets was significantly increased after treatment (90±7)% when compared with that before treatment (75±17)% ( t=-2.440, P<0.05). ② The mean fluorescence intensity of CXCR4 + lymphocyte subsets was significantly decreased after treatment [119.00(92.93, 142.50)] compared with that before treatment [177.00(130.75, 280.25)] ( Z=-2.100, P<0.05). ③ The plasma concentration of CXCL12 was significantly decreased after treatment (540±243) pg/ml when compared with that before the treatment (1 146±570) pg/ml ( t=3.219, P<0.05). ④ Moreover, there were significant correlations between the trends of the above three indicators after treatment. Conclusion:The proportion, the mean fluorescence intensity of CXCR4 + lymphocyte in peripheal blood subsets and the concentration of CXCL12 in plasma of first visit SLE patients are significantly changed after treatment. That suggests CXCL12/CXCR4 is closely associated with SLE.

ABSTRACT

Objective:To explore the application of four-dimensional automatic left atrial quantitation (4D LAQ) in evaluating left atrial function in patients with essential hypertension (EH) and to find the independent correlative factors affecting left atrial function.Methods:Fifty patients with EH(EH group) and fifty healthy controls(control group) were selected from Fuwai Center China Cardiovascular Hospital from September 2020 to January 2021. Conventional two-dimensional echocardiography was performed, and 4D LAQ parameters, including left atrial minimum volume (LAVmin), left atrial maximum volume (LAVmax), left atrial pre-systolic volume (LAVpreA), left atrial maximum volume index (LAVImax), left atrial reservoir longitudinal strain (LASr), left atrial conduit longitudinal strain (LAScd) and left atrial contraction longitudinal strain (LASct) was analyzed. The independent sample t-test or rank sum test was used to compare the EH group with the normal control group, and ROC curves were used to find the most sensitive parameters for evaluating left atrial function and their correlations were investigated by univariate and multivariate linear regression analyses. Results:Compared with the control group, there was no difference in left ventricular ejection fraction (LVEF) ( P>0.05), LAVmin, LAVmax, LAVpreA and LAVImax increased significantly (all P<0.05), the absolute values of LASr, LAScd and LASct were decreased (all P<0.05). ROC curve analysis showed that LASr had the best performance in evaluating left atrial function in EH patients (AUC: 0.929), systolic blood pressure (SBP), relative wall thickness (RWT) and E/e′ were negatively correlated with LASr (β=-0.308, P<0.05; β=-0.219, P<0.05; β=-0.359, P<0.05). Conclusions:4D LAQ can early identify the changes of left atrial function in EH patients, and the longitudinal strain in the left atrial reservoir period, left atrial conduit period and left atrial contraction period are all impaired in EH patients. LASr has the highest evaluation efficiency in evaluating the left atrial function, and SBP, RWT and E/e′ are independently correlated with LASr.

ABSTRACT

Objective:To investigate the clinical effect of ultrasonic root canal intermittent irrigation in endodontic vascular reconstruction.Methods:32 young permanent teeth with pulp and periapical lesions were randomly divided into two groups ( n=32): experimental group was treated with ultrasonic root canal intermittent irrigation and the control group was rinsed with sodium hypochlorite root canal. The changes of periapical lesions and root development were evaluated by preoperative and postoperative clinical symptom observation and radiograph examination, and the clinical effect of endodontic vascular reconstruction was discussed. The time of inflammation control was discussed by analyzing the starting point from the first diagnosis to the date of mineral trioxide aggregate (MTA) coverage. Results:The clinical symptoms of the 16 affected teeth in the experimental group and the control group disappeared, the periapical lesions were eliminated, and the root continued to develop. In the experimental group, root formation was observed in 13 of the affected teeth, with a success rate of 81.25% and a reduction rate of 18.75%. In the control group, root formation was observed in 10 of the affected teeth, with a success rate of 62.5% and a reduction rate of 37.5%. There was no difference in the effective rate between the experimental group and the control group ( P>0.05). The control time of inflammation was (28.44±5.98)days in the experimental group and (34.13±7.17)days in the control group, with statistically significant differences ( P<0.05). Conclusions:Ultrasonic root canal intermittent swabbing applied to pulp revascularization can achieve good clinical effect and shorten the time of inflammation control.

ABSTRACT

Objective:To evaluate the effectiveness of interventional treatment for neonatal critical pulmonary stenosis(NCPS).Methods:Clinical data of 12 neonates with NCPS who received percutaneous balloon pulmonary valvuloplasty (PBPV) from January 2016 to December 2019 in Department of Cardiology, Shenzhen Children′s Hospital were summarized and analyzed.The collected data included transthoracic echocardiography (TTE), percutaneous oxygen saturation (SPO 2), relevant data on interventional surgery, and follow-up results. Results:All 12 neonates with NCPS received PBPV successfully.The postoperative pressure difference between the right ventricle and the pulmonary artery ranged from 8 to 35 mmHg[(20±7) mmHg, 1 mmHg=0.133 kPa]. The postoperative SPO 2 ranged from 74%-100%[(93.0±5.9)%]. Three neonates with NCPS received Blalock-Taussig (B-T) shunt.One neonate with NCPS developed supraventricular tachycardia during the operation.There was no death for these 12 neonates with NCPS. Conclusions:Interventional treatment of neonates with NCPS could achieve a better effect and be employed as the first treatment option.Some neonates with NCPS would require cardiac B-T shunt or patent ductus arteriosus stent implantation.

ABSTRACT

Obesity is an independent risk factor for many chronic diseases, which seriously affects the quality of life and physical and mental health of patients, and is a serious public health problem facing society. Obesity research is the focus and difficulty of current medical research. At present, laparoscopic sleeve gastrectomy and gastric bypass surgery have become important ways to treat obesity, but the specific mechanism is still unclear. In recent years, research on obesity-related genes has made certain progress. The link between surgery and obesity gene expression is gradually being discovered. Different gene functions such as energy intake and consumption and fat storage by fat cells have also derived different treatment methods. This article will summarize the research on obesity genes.

ABSTRACT

Hydroxytyrosol as one of natural anti-oxidants,extracted from the fruits and leaves of Olea europaea,is a natural polyphenol compound in the form of esters. Recently,considerable studies showed that hydroxytyrosol demonstrated intrinsic biological activity for metabolic syndromes, cardiovascular- and neurodegenerative-related diseases,and it was revealed to play the roles in the anti-activities of cancerous,inflammatory as well as depressing issues. In addition,hydroxytyrosol is an oleophilic and hydrophilic compound with high bioavailability and low cellular cytotoxicity. It could be absorbed by various tissues and could easily passe through blood brain barrier. Therefore,hydroxytyrosol was introduced as one of the key subjects targeted by innovative drug development. However,it has a short half-life in vivo and non-tissue specific,which lead to its limitation in clinical application, so further in-depth studies are still needed. The authors had a literature review of hydroxytyrosol,and summarized the basic properties of its pharmacokinetic,pharmacological effects and molecular mechanisms. This article mainly focused on it’s pharmacological activity and the mechanism involved in treating damages induced by the oxidative stress,in alleviating cardiovascular diseases and in inhibition of neurodegenerative diseases. In this article, its anti-inflammatory,anti-tumor,anti-depressant effects,other biological activities,and pharmacokinetics were also briefly reviewed. The authors put forward some personal thoughts on its future research direction,hoping to provide ideas and inspirations for the vast number of researchers,and provide references for its further development,research and application.

ABSTRACT

Objective:To investigate the association between serum trace elements and dyslipidemia in Pudong New Area. Methods:A community-based cross-sectional study was carried out. A stratified, cluster sampling approach was used for sampling. In total 1 814 community residents aged above 35 years old were recruited in Pudong New Area, Shanghai. A face-to-face investigation was conducted and blood samples were collected. Serum levels of 16 trace elements, including boron, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, strontium, molybdenum, tin, antimony, and barium were measured by inductively coupled plasma mass spectrometry (ICP-MS). The relationship between serum trace elements and dyslipidemia was analyzed with single and multiple Logistic regression models. Results:Prevalence of dyslipidemia is higher among participants of more than 45 years old with high BMI, hypertension or diabetes.Serum iron leveled the highest, followed by copper, zinc, selenium, strontium, boron and other trace elements. After adjusting for potential confounders, the odds ratios of dyslipidemia associated with the highest quartile of trace elements concentrations were 1.41 (95%CI: 1.12-1.78), 0.77 (95%CI: 0.61-0.96), 1.65 (95%CI: 1.31-2.09), 1.27 (95%CI: 1.02-1.58), and 1.32 (95%CI: 1.06-1.66) for chromium, cobalt, zinc, arsenic, and tin, respectively, compared with that associated with the other three quartiles. Conclusion:Some serum trace elements are potentially associated with dyslipidemia in community residents.
