Efficient organized colorectal cancer screening in Shenzhen: a microsimulation modelling study.

BACKGROUND: Colorectal cancer (CRC) is a global health issue with noticeably high incidence and mortality. Microsimulation models offer a time-efficient method to dynamically analyze multiple screening strategies. The study aimed to identify the efficient organized CRC screening strategies for Shenzhen City. METHODS: A microsimulation model named CMOST was employed to simulate CRC screening among 1 million people without migration in Shenzhen, with two CRC developing pathways and real-world participation rates. Initial screening included the National Colorectal Polyp Care score (NCPCS), fecal immunochemical test (FIT), and risk-stratification model (RS model), followed by diagnostic colonoscopy for positive results. Several start-ages (40, 45, 50 years), stop-ages (70, 75, 80 years), and screening intervals (annual, biennial, triennial) were assessed for each strategy. The efficiency of CRC screening was assessed by number of colonoscopies versus life-years gained (LYG). RESULTS: The screening strategies reduced CRC lifetime incidence by 14-27 cases (30.9-59.0%) and mortality by 7-12 deaths (41.5-71.3%), yielded 83-155 LYG, while requiring 920 to 5901 colonoscopies per 1000 individuals. Out of 81 screening, 23 strategies were estimated efficient. Most of the efficient screening strategies started at age 40 (17 out of 23 strategies) and stopped at age 70 (13 out of 23 strategies). Predominant screening intervals identified were annual for NCPCS, biennial for FIT, and triennial for RS models. The incremental colonoscopies to LYG ratios of efficient screening increased with shorter intervals within the same test category. Compared with no screening, when screening at the same start-to-stop age and interval, the additional colonoscopies per LYG increased progressively for FIT, NCPCS and RS model. CONCLUSION: This study identifies efficient CRC screening strategies for the average-risk population in Shenzhen. Most efficient screening strategies indeed start at age 40, but the optimal starting age depends on the chosen willingness-to-pay threshold. Within insufficient colonoscopy resources, efficient FIT and NCPCS screening strategies might be CRC initial screening strategies. We acknowledged the age-dependency bias of the results with NCPCS and RS.

Cavernous Sinus Syndrome Caused by Noninvasive Fungal Maxillary Sinusitis.

It is rare that cavernous sinus complications are caused by maxillary sinus lesions because the locations of these lesions are some distant from each other. The authors describe an unusual presentation that the primary lesion was located in the maxillary sinus and triggered cavernous sinus syndrome and optic nerve symptoms. The most likely possibility was that the infection traveled retrograde along the vascular plexus. Removal of maxillary sinus lesions and establishment ventilation may achieve source control.

Orbital solitary fibrous tumours: clinicopathological characteristics and recurrence prediction.

BACKGROUND: SFTs are thought to have an unpredictable clinical course and currently have no recognized prognostic criterion. Our study aimed to determine the relationship between clinicopathological characteristics and the prognosis of patients with orbital SFTs. METHODS: The clinicopathological features of these patients were extracted from clinical records. The relationships between these features and prognosis were analysed. RESULTS: The positive rates of CD34, CD99, Blc2, and STAT6 expression were 90.3%, 90.3%, 83.9%, and 100%, respectively. The tumour recurrence rate was 38.7%. A higher recurrence rate was observed in patients with Ki67 index ≥ 5 (56.25% vs. 20%, P = 0.038). CONCLUSION: A Ki67 index ≥ 5 was an effective parameter for predicting tumour recurrence of orbital SFTs. Close follow-up is needed for these patients.

Erdheim-Chester disease with bilateral orbital masses and multi-systemic symptoms: two case reports.

BACKGROUND: Erdheim-Chester disease (ECD) is a rare histiocytic disorder characterized by multisystem xanthogranulomatous infiltration by lipid-laden histiocytes. We report two cases of ECD involving the orbit and describe their clinicopathologic factors, treatments, and prognosis. One was a rare case of ECD complicated with primary thrombocytosis. CASE PRESENTATION: This study describes two patients with bilateral orbital ECD. Both presented with proptosis and visual loss; imaging findings showed bilateral intraorbital masses. Both had different degrees of systemic symptoms (pleural effusion, pericardial effusion, ascites, and heart failure) before the ocular symptoms and did not find the cause before ophthalmic tumor resection and pathological biopsy. The diagnosis of ECD was confirmed after pathological biopsy and detection of BRAFV600E mutation. Patient 2 also with primary thrombocytosis and had a CALR mutation as well as the BRAFV600E mutation. Both patients were recommended to receive targeted therapy. Patient 1 refused targeted therapy for financial reasons and was discharged after local radiotherapy only. The patient had no light perception in either eye and no improvement in systemic symptoms. Patient 2 began targeted treatment after diagnosis and reached the discharge criteria 2 weeks later. He is in good condition at present, but unfortunately, his eyesight has not improved because of the irreversible damage to his visual function. CONCLUSION: ECD is easily misdiagnosed and missed because of its rarity and diverse clinical manifestations. Orbital involvement is common in ECD, and surgery is the most frequently employed approach. Despite the surgical resection is not curative, its significance lies in biopsy to establish diagnosis and/or surgical debulking to relieve mass effect, minimizing further impairment of visual function. Targeted therapy is the most effective treatment for patients with a positive BRAF mutation gene. Evaluation of a concomitant myeloid neoplasm is also critical before initiating targeted therapies for refractory ECD.

Nasal Sinus Mucoceles Manifesting Ocular Symptoms.

INTRODUCTION: To describe the ocular symptoms in a series of patients with nasal sinus mucoceles of different locations. METHODS: The authors analyzed the diagnosis and treatment of patients with sinus mucoceles and ocular symptoms who presented to the hospital from February 2010 to April 2020. A total of 61 patients were included in the study. The locations of the mucoceles were the frontal sinus (8 patients), ethmoid sinus (25 patients), and sphenoid sinus (28 patients). The authors selected 1 typical mucocele case from each of the sinuses, including the frontal, ethmoid, and sphenoid sinuses, and analyzed the history, diagnosis, and treatment of mucoceles in each location. RESULTS: The main clinical manifestations were ophthalmic symptoms, such as exophthalmos or displacement, eye pain, blindness or decreased vision, blepharoptosis, and diplopia; no obvious nasal symptoms were noted. Most patients with these symptoms went to an ophthalmologist first. All lesions in this study were found through imaging examinations. Most symptoms improved after surgical interventions. Only 2 of the 61 patients had no improvement in vision because of the long period of vision loss. CONCLUSIONS: Although sinus mucoceles are located in the sinuses, ocular symptoms are more prevalent than nasal symptoms. The earlier the imaging examinations are performed; the sooner lesions are detected, and the patients can be treated.

The association between Chinese Visceral Adipose Index and coronary heart disease: A cohort study in China.

BACKGROUND AND AIMS: The purpose of this study is to explore the relationship between Chinese visceral adipose index (CVAI) and the risk of coronary heart disease (CHD) in Chinese through a large cohort study. METHODS AND RESULTS: This study included 42,165 adults who were without CHD at baseline and who completed at least one annual follow-up between 2009 and 2016. We used the Cox proportional hazards model to estimate Hazard Ratios (HRs) and 95% Confidence Intervals (CIs) for the association between CVAI and risk of CHD. During the median follow-up of 3.36 years (154,808 person years), 520 participants developed CHD, including 374 males and 146 females. Compared with the first quartile of CVAI, the risk of CHD was significantly increased in the fourth quartile of CVAI in multivariate model (HR [95% CI]: 9.92 [5.45, 18.04], P < 0.001). Sensitivity analysis by excluding incident CHD developed in the first two years of follow-up reinforced our results. Gender stratification analyses showed that the relationship between CVAI and CHD risk was higher in males than that in females. The restricted cubic spline showed a non-linear dose-response relationship between CVAI and CHD risk. In addition, CVAI was associated with CHD risk in the subgroups of participants without T2DM, without hypertension, and without fatty liver. CONCLUSION: CVAI was significantly associated with the risk of CHD. Individuals should keep CVAI at normal level to prevent CHD.

The association between low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio cholesterol ratio and thickened carotid intima-media thickness: A case-control study.

BACKGROUND: It is indicated that Low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (LDL-C/HDL-C ratio) has greater predictive value for thickened carotid intima-media thickness (CIMT) comparing with classic lipid parameters. However, there have been few reports about their association in general Chinese population. METHOD: We included a total of 1220 CIMT participants and 2440 matched controls, who had ultrasonography of carotid artery during 2009 and 2016. Univariate and multivariate logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for thickened CIMT risk associated with LDL-C/HDL-C ratio. RESULT: In the univariate logistic regression model, there was significant association between LDL-C/HDL-C ratio and thickened CIMT (Q4 vs. Q1, OR = 1.94, 95% CI: 1.60-2.36; ptrend < 0.05). After adjusting for potential covariates, LDL-C/HDL-C ratio remained significantly associated with thickened CIMT (Q4 vs. Q1, OR = 1.81, 95% CI: 1.41-2.34, ptrend < 0.001; ≥3.05 v.s. <3.05, OR = 1.66, 95% CI: 1.37-2.02). In subgroup analyses, the association between LDL-C/HDL-C ratio and thickened CIMT remained significant in the subgroups stratified by sex, impaired fasting glucose (IFG), hypertension, and fatty liver disease but only remained significant in the subgroups of ≥45 years (OR = 2.01, 95% CI: 1.46-2.76; Ptrend<0.05), BMI ≥24 (kg/m2) (OR = 2.22; 95% CI = 1.63-3.03; Ptrend < 0.05) and BMI ≥25 (kg/m2) (OR = 2.50, 95% CI: 1.76-3.54; Ptrend < 0.05), dyslipidemia (OR = 3.28, 95% CI: 1.83-5,85; Ptrend < 0.001), and without periodontitis (OR = 2.08, 95% CI: 1.54-2.81 ; Ptrend < 0.05) comparing Q4 to Q1. Similar results were observed in the subgroup analyses for LDL-C/HDL-C ratio ≥3.05 v.s. <3.05 except for the age stratification. CONCLUSION: High LDL-C/HDL-C ratio could significantly increase the risk of thickened CIMT independent of gender, IFG, hypertension, and fatty liver disease in general Chinese population.

Platelet-Lymphocyte Ratio, Neutrophil-Lymphocyte Ratio and Their Dynamic Changes with Type 2 Diabetes Mellitus: A Cohort Study in China.

BACKGROUND: This study aimed at investigating the relationships between Platelet-Lymphocyte ratio (PLR) and Neutrophil-Lymphocyte ratio (NLR) and their dynamic changes (∆PLR, ∆NLR) with type 2 diabetes mellitus (T2DM) in a Chinese cohort study. METHODS: This study recruited 41,439 individuals who were diagnosed without T2DM at first health examination and completed at least one follow-up. The relationships between NLR, PLR, ∆PLR, ∆NLR and T2DM risk were analyzed using the Cox regression model with corresponding Hazard Ratios (HRs) and 95% Confidence Intervals (CIs). RESULTS: PLR exhibited significant correlation with T2DM risk in a linear reverse dose-response pattern, the corresponding HRs and 95% CIs were 0.81 (0.72, 0.90), 0.71 (0.63, 0.80) and 0.56 (0.49, 0.64) respectively (Ptrend < 0.001) for Q2, Q3 and Q4 vs Q1 after adjusting for age, gender, BMI, TG, TC, HDL-C, FPG, ALT, AST, heart rate, smoking, family history of diabetes, and alcohol consumption at baseline in Model 3. The significance remained in subgroups of women, <45 years, ≥45 years, BMI ≥ 24, with fatty liver disease, without fatty liver disease and normotension. Comparing with the largest decrease group of NLR (∆NLR < -0.32), the risk of T2DM increased for -0.003 ≤ ∆NLR < 0.31 (HR 1.17, 95% CI 1.01-1.36) and ∆NLR ≥ 0.31 (HR 1.23, 95% CI 1.06-1.43). CONCLUSIONS: Higher PLR could reduce the risk of T2DM. Larger increase of NLR could increase T2DM risk.

A fecal-based test for the detection of advanced adenoma and colorectal cancer: a case-control and screening cohort study.

BACKGROUND: Colorectal cancer (CRC) is the leading cause of cancer death worldwide. Screening is a confirmed way to reduce the incidence and mortality rates of CRC. This study aimed to identify a fecal-based, noninvasive, and accurate method for detection of colorectal cancer (CRC) and advanced adenoma (AA). METHODS: Through detection in tissue (n = 96) and fecal samples (n = 88) and tested in an independent group of fecal samples (n = 294), the methylated DNA marker ITGA4 and bacterial markers Fusobacterium nucleatum (Fn) and Pepetostreptococcusanaerobius (Pa) were identified from the candidate biomarkers for CRC and AA detection. A prediction score (pd-score) was constructed using the selected markers and fecal immunochemical test (FIT) for distinguishing AA and CRC from healthy subjects by logistic regression method. The diagnostic performance of the pd-score was compared with FIT and validated in the external validation cohort (n = 117) and in a large CRC screening cohort. RESULTS: The pd-score accurately identified AA and CRC from healthy subjects with an area under the curve (AUC) of 0.958, at a specificity of 91.37%; the pd-score showed sensitivities of 95.38% for CRC and 70.83% for AA, respectively. In the external validation cohort, the sensitivities of the pd-score for CRC and AA detection were 94.03% and 80.00%, respectively. When applied in screening, the pd-score identified 100% (11/11) of CRC and 70.83% (17/24) of AA in participants with both colonoscopy results and qualified fecal samples, showing an improvement by 41.19% compared to FIT. CONCLUSIONS: The current study developed a noninvasive and well-validated approach for AA and CRC detection, which could be applied widely as a diagnostic and screening test.

Anthocyanins regulate serum adipsin and visfatin in patients with prediabetes or newly diagnosed diabetes: a randomized controlled trial.

BACKGROUND: Epidemiological studies have suggested that adipsin and visfatin are associated with the development of type 2 diabetes. This is the first study to investigate the effects of supplementation with purified anthocyanins on serum adipsin and visfatin in patients with prediabetes or newly diagnosed diabetes. METHODS: A total of 160 participants with prediabetes or newly diagnosed diabetes (40-75 years old) were given 320 mg anthocyanins or placebo daily for 12 weeks in a randomized trial. Serum adipsin, serum visfatin, lipids and glycated hemoglobin A1c (HbA1c) were measured. The areas under the curve (AUCs) for glucose, insulin and C-peptide were determined before-and after-treatment by a standard 3-h 75 g oral glucose tolerance test (OGTT). RESULTS: Relatively significant increases in serum adipsin (net change 0.15 µg/mL [0.03, 0.27], p = 0.018) and decreases in visfatin (-3.5 ng/mL [-6.69, -0.31], p = 0.032) were observed between the anthocyanins and placebo groups. We also observed significant improvements in HbA1c (-0.11% [-0.22, -0.11], p = 0.033), apolipoprotein A-1 (apo A-1) (0.12 g/L [0.03, 0.21], p = 0.012) and apolipoprotein B (apo B) (-0.07 g/L [-0.14, -0.01], p = 0.033) in response to the anthocyanins intervention. CONCLUSION: Purified anthocyanins supplementation for 12 weeks increased serum adipsin and decreased serum visfatin in patients with prediabetes or newly diagnosed diabetes. Trial registration ClinicalTrials.gov, identifier: NCT02689765.

Dose-response association of the ZJU index and fatty liver disease risk: A large cohort in China.

AIM: The aim of this study is to investigate the sex-specific association between the ZJU index and risk of fatty liver disease in a large Chinese cohort. METHODS: A total of 28 729 adults without fatty liver disease at baseline and who completed at least one follow-up of annual examinations between 2009 and 2016 were included in this study. The Cox proportional hazards model was used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) for fatty liver disease risk associated with the ZJU index. RESULTS: During a median follow-up of 3.01 years, 7373 developed fatty liver disease. There were significant associations between the ZJU index and fatty liver disease for women and men with increasing HRs as the quartiles increase across Q2-Q4, corresponding HRs (95% CIs) in M3 were 2.28 (1.98-2.64), 3.52 (3.07-4.04), and 4.87 (4.24-5.59) for women and 2.44 (2.17-2.75), 4.18 (3.73-4.68), and 6.23 (5.56-6.98) for men. The association between the ZJU index and fatty liver disease risk remained significant in all the subgroups except that of T2DM and abdominal obesity subgroups for men. However, the association became nonsignificant when comparing Q3 and Q2 of the ZJU index with reference in the subgroups of T2DM for men, and nonsignificant when comparing Q3 of the ZJU index with reference in the subgroups of participants with T2DM and abdominal obesity for women. CONCLUSION: The ZJU index was significantly associated with the risk of fatty liver disease in Chinese population. It will be better to keep body mass index, alanine aminotransferase, aspartate aminotransferase, triglyceride, and fasting plasma glucose at a normal level for preventing fatty liver disease.

Association between blood urea nitrogen and incidence of type 2 diabetes mellitus in a Chinese population: a cohort study.

To examine the association between blood urea nitrogen (BUN) and risk of type 2 diabetes (T2DM) among Chinese adults, we performed an ongoing cohort study of 38578 Chinese adults (56.3% males; average age, 41.6 y) who underwent repeated health check-up examinations between 2009 and 2016 and without T2DM at baseline. During follow-up, incident T2DM cases were identified based on self-report, medication use, measurements of fasting plasma glucose, 2 h post oral glucose, or haemoglobinA1c. 2009 (5.2%) cases confirmed with incident T2DM were identified during median follow-up of 3.1 years. With increasing quartiles of BUN levels, the incidences of T2DM gradually increased with 0.69%, 1.11%, 1.53%, and 1.87% for quartile 1 to quartile 4 (p trend <0.001). Compared with quartile 1, the multivariate-adjusted hazard ratios (HRs) and its 95% confidence intervals (95% CIs) for T2DM risk were 1.16 (0.97-1.38) for quartile 2, 1.28 (1.07-1.51) for quartile 3, and 1.28 (1.08-1.52) for quartile 4 (p trend = 0.005). HR for per each standard deviation increase in BUN level was 1.10 (1.04-1.16) (p trend <0.001). This association tended to be more pronounced in those with a lower body mass index at baseline (p-interaction <0.001). Our results suggested that BUN levels were positively associated with incident T2DM risk among Chinese adults. Future prospective investigations in other populations are necessary to confirm our findings.

N-Heterocyclic Carbene-Catalyzed Atroposelective Annulation for Access to Thiazine Derivatives with C-N Axial Chirality.

A catalytic atroposelective cycloaddition reaction between thioureas and ynals is developed. This reaction features the first NHC-catalyzed addition of thioureas to acetylenic acylazolium intermediates to eventually set up C-N axial chirality with excellent optical purities. The obtained axially chiral thiazine derivative products bear multiple functional groups and are feasible for further transformations.

Association of plasma ß-amyloid 40 and 42 concentration with type 2 diabetes among Chinese adults.

AIMS/HYPOTHESIS: There is evidence for a bidirectional association between type 2 diabetes and Alzheimer's disease. Plasma ß-amyloid (Aß) is a potential biomarker for Alzheimer's disease. We aimed to investigate the association of plasma Aß40 and Aß42 with risk of type 2 diabetes. METHODS: We performed a case-control study and a nested case-control study within a prospective cohort study. In the case-control study, we included 1063 newly diagnosed individuals with type 2 diabetes and 1063 control participants matched by age (±3 years) and sex. In the nested case-control study, we included 121 individuals with incident type 2 diabetes and 242 matched control individuals. Plasma Aß40 and Aß42 concentrations were simultaneously measured with electrochemiluminescence immunoassay. Conditional logistic regression was used to evaluate the association of plasma Aß40 and Aß42 concentrations with the likelihood of type 2 diabetes. RESULTS: In the case-control study, the multivariable-adjusted ORs for type 2 diabetes, comparing the highest with the lowest quartile of plasma Aß concentrations, were 1.97 (95% CI 1.46, 2.66) for plasma Aß40 and 2.01 (95% CI 1.50, 2.69) for plasma Aß42. Each 30 ng/l increment of plasma Aß40 was associated with 28% (95% CI 15%, 43%) higher odds of type 2 diabetes, and each 5 ng/l increment of plasma Aß42 was associated with 37% (95% CI 21%, 55%) higher odds of type 2 diabetes. Individuals in the highest tertile for both plasma Aß40 and Aß42 concentrations had 2.96-fold greater odds of type 2 diabetes compared with those in the lowest tertile for both plasma Aß40 and Aß42 concentrations. In the nested case-control study, the multivariable-adjusted ORs for type 2 diabetes for the highest vs the lowest quartile were 3.79 (95% CI 1.81, 7.94) for plasma Aß40 and 2.88 (95% CI 1.44, 5.75) for plasma Aß42. The multivariable-adjusted ORs for type 2 diabetes associated with each 30 ng/l increment in plasma Aß40 and each 5 ng/l increment in plasma Aß42 were 1.44 (95% CI 1.18, 1.74) and 1.47 (95% CI 1.15, 1.88), respectively. CONCLUSIONS/INTERPRETATION: Our findings suggest positive associations of plasma Aß40 and Aß42 concentration with risk of type 2 diabetes. Further studies are warranted to elucidate the underlying mechanisms and explore the potential roles of plasma Aß in linking type 2 diabetes and Alzheimer's disease.

Baseline serum albumin and its dynamic change is associated with type 2 diabetes risk: A large cohort study in China.

BACKGROUND: The study aimed to investigate the associations of baseline serum albumin level and its dynamic change with type 2 diabetes mellitus (T2DM) risk in a large Chinese cohort study. METHODS: This cohort study included 30 442 adults without T2DM at first entry, who completed at least one follow-up of annual examinations between 2009 and 2016. Serum albumin level was measured at baseline and at every annual check-up. The dynamic change in serum albumin level (∆ALB) was calculated by subtracting serum albumin level at baseline from that at the last follow-up. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated with Cox regression models. RESULTS: During 7 years of follow-up, we identified 1634 T2DM events. From the lowest to the highest quartile of serum albumin level, adjusted HRs (95% CI) were 1.00 (reference), 0.96 (0.94, 1.01), 0.98 (0.95, 1.02) and 0.88 (0.85, 0.98), respectively. As compared with stable change in serum albumin (-0.2 ≤ ∆ALB <1.0 g/L), the risk of T2DM increased for ∆ALB < -2.0 g/L (HR 1.44, 95% CI 1.24-1.68) and decreased for ∆ALB ≥3.0 g/L (0.81, 0.68-0.97) after adjusting for potential confounding factors. Restricted cubic splines showed a linear dose-response association between baseline serum albumin level and T2DM risk (Pnonlinearity 0.715) and a nonlinear dose-response association between ∆ALB and T2DM risk (Pnonlinearity 0.011). CONCLUSIONS: Baseline serum albumin level appears to be inversely associated with T2DM risk. Adults with reduced serum albumin level could be early identified for diabetes risk in clinical practice.

Simultaneous separation and determination of vancomycin and its crystalline degradation products in human serum by ultra high performance liquid chromatography tandem mass spectrometry method and its application in therapeutic drug monitoring.

A rapid and simple ultra high performance liquid chromatography with tandem mass spectrometry method was developed and validated for the simultaneous separation and determination of vancomycin and its crystalline degradation products in human serum. Vancomycin and two isomers of the degradants were extracted from human serum with a protein precipitation method. The compounds were separated on an Acquity BEH C18 column (2.1 × 50 mm, 1.7 µm) eluted with a gradient mixture of acetonitrile and 0.1% formic acid as the mobile phase. Norvancomycin was used as the internal standard. The linear ranges of vancomycin and two degradant isomers were 1.057-105.7, 0.1437-14.37, and 0.2540-25.40 µg/mL, respectively. The established methods were validated and successfully applied to a therapeutic drug monitoring study of vancomycin in patients with renal insufficiency.

Effects of fish oil supplementation on glucose control and lipid levels among patients with type 2 diabetes mellitus: a Meta-analysis of randomized controlled trials.

BACKGROUND: Previous studies have yielded inconsistent findings on the role of fish oil in type 2 diabetes mellitus (T2DM). We systematically summarized the available evidence from randomized controlled trials (RCT) and aimed to investigate the effects of fish oil supplementation on glucose control and lipid levels among patients with T2DM. METHODS: A comprehensive literature search was performed in electronic databases (PubMed, ProQuest, Cochrane Library, CNKI, VIP, and Wanfang) to identify all relevant RCTs which were published up to May 31st, 2019. We used Modified Jadad Score system to evaluate the quality of each included RCT. The pooled effects were estimated using random-effects model and presented as standardized mean differences with 95% confidence intervals. RESULTS: A total of 12 RCTs were included in this meta-analysis. There was no significant difference in glucose control outcomes comparing fish oil supplementation to placebo. The effect size of fasting plasma glucose (FPG) was 0.13 (95% CI: - 0.03 to 0.28, p > 0.05). No marked change was observed in fasting insulin (FINS), glycosylated hemoglobin (HbA1c), and HOMA of insulin resistance (HOMA-IR) levels. Fish oil supplementation was associated with a decrease of triglyceride (TG) level by - 0.40 (95%CI: - 0.53 to - 0.28, p < 0.05), and an increase of high density lipoprotein (HDL) cholesterol level by 0.21 (95%CI: 0.05 to 0.37, p < 0.05). In subgroup analysis, HDL cholesterol level was higher among Asian and low-dose(< 2 g/d n-3 PUFA) subgroups compared to their counterparts (p < 0.05). TG level was lower in mid and long duration groups, along with an inconspicuous difference in short duration group. CONCLUSIONS: This meta-analysis shows that among patients with T2DM, fish oil supplementation leads to a favorable blood lipids profile but does not improve glucose control.

LDL-cholesterol to HDL-cholesterol ratio discordance with lipid parameters and carotid intima-media thickness: a cohort study in China.

BACKGROUND: The discordance of the low-density lipoprotein cholesterol-to-high-density lipoprotein cholesterol (LDL-C/HDL-C) ratio with alterative lipid parameters may explain the inconsistent association of CIMT with the LDL-C/HDL-C ratio. Therefore, this study aimed to explore the associations between LDL-C/HDL-C ratio discordance with alternative lipid parameters and elevated carotid intima-media thickness (CIMT) risk in a large cohort in Beijing, China. METHODS: In total, 13,612 adults who didn't have elevated CIMT at baseline and who participated in at least one follow-up of annual examination between 2009 and 2016 were included in this cohort study. A multivariable Cox regression model was utilized to evaluate the associations of discordance of the LDL-C/HDL-C ratio with TC, TGs, LDL-C and HDL-C with elevated CIMT risk. RESULTS: During 37,999 person-years of follow-up, 2004 individuals (1274 men and 730 women) developed elevated CIMT. Among individuals with normal TC and TGs, 16.6 and 15.2% individuals had a discordantly high LDL-C/HDL-C ratio, respectively, and the risk of elevated CIMT increased by 1.54 (95% CI 1.33, 1.77) and 1.53 (95% CI 1.33, 1.76), respectively, comparing to individuals with a concordantly low LDL-C/HDL-C ratio. A high LDL-C/HDL-C ratio could significantly increase elevated CIMT risk regardless of discordance/concordance with LDL-C and HDL-C (P < 0.001). A low LDL-C/HDL-C ratio with discordantly normal HDL-C and high LDL-C (13.2% of individuals) had a 32% (HR = 1.32, 95% CI 1.11, 1.57) higher risk of elevated CIMT than concordantly low LDL-C and normal HDL-C. Sensitivity analysis by excluding CIMT developed in the first 2 years follow-up further confirmed the above results. CONCLUSIONS: A high LDL-C/HDL-C ratio could significantly increase elevated CIMT risk regardless of discordance/concordance with TC, TGs, LDL-C and HDL-C Even a low LDL-C/HDL-C ratio with discordantly high LDL-C and normal HDL-C could also significantly increase CIMT risk. Individuals should maintain both the LDL-C/HDL-C ratio and LDL-C at normal levels to prevent elevated CIMT.

Bilateral IgG4-related Ophthalmic Disease With Diffuse Large B-cell Lymphoma of the Right Eye: A Case Report.

Lymphoma is common in IgG4-related disease, but diffuse large B-cell lymphoma in IgG4-related ophthalmic disease is rare, especially involving the same organ affected by IgG4-related ophthalmic disease. The authors report a 44-year-old man presented with bilateral proptosis for 10 years and rapid loss of vision in the right eye for the last 1 month. The authors performed orbital exenteration for the right eye and resected the tumor in the left eye. Based on the clinicopathologic findings, tumors of the right and left eyes were diagnosed as diffuse large B-cell lymphoma and IgG4-related ophthalmic disease, respectively.

Molecular characterization and bioactivity evaluation of two novel bombinin peptides from the skin secretion of Oriental fire-bellied toad, Bombina orientalis.

Following the exploration of biochemicals in amphibian defensive skin secretion, great attention has been focused on the novel bioactive peptides with unique molecular structures and complicated features and functions. In this study, the skin secretion of Oriental fire-bellied toad, Bombina orientalis, was acquired to search peptides with therapeutic potential. Using "shotgun" cloning technique, a full-length peptide precursor co-encoding two novel bombinin peptides was cloned from the skin secretion-derived cDNA library of B. orientalis. The deduced peptides were identified as one bombinin-like peptide (BLP) (GIGSAILSAGKSIIKGLAKGLAEHF-NH2) and one bombinin H-type peptide (BH) (IIGPVLGLVGKALGGLL-NH2). The primary structures of both peptides were confirmed through reverse-phase HPLC fractionation and mass spectrometry. Secondary structural prediction revealed Bombinin-BO1 and Bombinin H-BO1 adopted α-helical structural features. In addition, the two peptides exhibited broad-spectrum antimicrobial effect against Gram-positive and Gram-negative bacteria and yeast. Meanwhile, the anticancer activity assay indicated both peptides exerted significant anticancer effects against human hepatoma cell lines tested (Hep G2/SK-HEP-1/Huh7). The peptides reported here for the first time may represent novel lead compounds for the design/development of new therapeutics for human infection and neoplastic disease.
