Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population: Findings from the China Cardiometabolic Disease and Cancer Cohort (4C) Study

Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.     

Full-Length Genome Sequencing of SARS-CoV-2 Directly from Clinical and Environmental Samples Based on the Multiplex Polymerase Chain Reaction Method

The new coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is spreading worldwide with the number of confirmed cases increasing dramatically[1,2]. Coronaviruses have the largest genome among RNA viruses and have caused two major outbreaks[3,4]. The new coronavirus (SARS-CoV-2) is the third coronavirus spread globally in the past 17 years. According to the World Health Organization, SARS-CoV-2 has affected more than 155.6 millon patients in 222 countries as of 6 May 2021 and has become a major global health concern (https://www.who.int/emergencies/diseases/novel-coronavirus-2019).     

B-learning在进修医生胎儿超声心动图教学中的应用

胎儿超声心动图是筛查、诊断胎儿先天性心脏病最有效的方法,其作为一门高难度的新兴学科,从业者需要具备扎实的理论知识和规范的操作技能,学习和掌握起来较为困难。而来我院学习胎儿超声心动图的进修医生,往往存在自身知识水平参差不齐、学习时间紧、任务重等特点,传统教学模式难以达到其学习的目的。我们探索将传统教学与计算机及网络教学相结合即混合式学习(B-learning)运用到进修医生胎儿超声心动图教学中,采用案例式教学、问题导向教学、多媒体教学等多元化教学手段,激发进修医生学习的主动性、积极性,培养其分析、思考问题的能力,提高教学质量,进而提高进修医生超声筛查和诊断胎儿先天性心脏病的能力。     

联合检验对珠蛋白生成障碍性贫血的诊断意义分析

目的 探讨联合检验对珠蛋白生成障碍性贫血的诊断意义.方法 选取2018年6月至2019年6月本院收治的20例珠蛋白生成障碍性贫血患者作为观察组,另选取同期健康体检者20名作为对照组.两组均统一进行联合检验,比较两组血液学指标检查结果,分析联合检验对珠蛋白生成障碍性贫血的诊断意义.结果 观察组RDW、HbA2水平均高于对照组,MCV水平、RBC脆性均低于对照组,差异有统计学意义(P<0.05).MCV与Hb电泳联合、MCV与RBC脆性联合及Hb电泳与RBC脆性联合的串联试验灵敏度较高,其并联试验的特异度较高.结论 联合检验有助于提升珠蛋白生成障碍性贫血的诊断准确性,值得临床推广应用.     

Attenuation of Reserpine-Induced Pain/Depression Dyad by Gentiopicroside Through Downregulation of GluN2B Receptors in the Amygdala of Mice

Epidemiological studies demonstrate that pain frequently occurs comorbid with depression. Gentiopicroside (Gent) is a secoiridoid compound isolated from Gentiana lutea that exhibits analgesic properties and inhibits the expression of GluN2B-containing N-methyl-d-aspartate (NMDA) receptors in the anterior cingulate cortex of mice. However, the effects of Gent on the reserpine-induced pain/depression dyad and its underlying mechanisms are unclear. Reserpine administration (1 mg/kg subcutaneous daily for 3 days) caused a significant decrease in the nociceptive threshold as evidenced by the reduced paw withdrawal latency in response to a radiant heat source and mechanical allodynia. Behavioral detection indicated a significant increase in immobility time during a forced swim test, as well as decreased time in the central area and total travel distance in an open field test. Furthermore, reserpinized animals exhibited increased oxidative stress. Systemic Gent administration dose-dependently ameliorated the behavioral deficits associated with reserpine-induced pain/depression dyad. At the same time, the decrease in biogenic amine levels (norepinephrine, dopamine, and serotonin) was integrated with the increase in caspase-3 levels and GluN2B-containing NMDA receptors in the amygdala of the reserpine-injected mice. Gent significantly reversed the changes in the levels of biogenic amines, caspase-3, and GluN2B-containing NMDA receptors in amygdala. However, Gent did not affect the expression of GluN2A-containing NMDA receptors. The inhibitory effects of Gent on oxidative stress were occluded by simultaneous treatment of GluN2B receptors antagonist Ro25-6981. Our study provides strong evidence that Gent inhibits reserpine-induced pain/depression dyad by downregulating GluN2B receptors in the amygdala.

The measurement of serum cholinesterase activities by an integration strategy with expanded linear ranges and negligible substrate-activation

Objectives

To measure serum cholinesterase (SCHE) with an integration strategy.

Design and methods

At 54.0 μmol/L butyrylthiolcholine, SCHE initial rates were calculated with 50.0 μmol/L butyrylthiolcholine and maximal rates via an improved integrated method if substrate consumptions within 5.0 min were over 60%, or were determined by the classical initial rate method.

Results

The linear range was from 16 to 1560 nkat/L, and SCHE in clinic sera showed negligible substrate-activation.

Conclusion

This strategy was effective.
