Painless Jaundice Caused by Clonorchis sinensis Infection: A Case Report

A man with only yellowing of the skin and eye sclera was diagnosed with clonorchiasis, which rarely manifested jaundice as the initial symptom. However, because of a lack of evidence for a diagnostic gold standard, the time until definitive diagnosis was more than a week. The diagnostic process relied on inquiring about the patient’s history, including the place of residence, dietary habits, and symptoms, as well as on serological findings, an imaging examination, and pathological findings. MRCP and CT results showed mild dilatation of intrahepatic ducts and increased periductal echogenicity. The eggs were ultimately found in stool by water sedimentation method after the negative report through direct smear. DNA sequencing of PCR production of the eggs demonstrated 98-100% homology with ITS2 of Clonorchis sinensis. After anti-parasite medical treatment, the patient’s symptoms were gradually relieved. Throughout the diagnostic procedure, besides routine examinations, the sedimentation method or concentration method could be used as a sensitive way for both light and heavy C. sinensis infection in the definite diagnosis.     

Time-related alterations of superoxide radical levels in diverse organs of bile duct-ligated rats

The time-related alterations of superoxide radical measured in vivo by employing an ultrasensitive fluorescent assay in the liver, intestine, kidney and brain of rats with experimentally induced obstructive jaundice was investigated. Eighteen rats were randomly divided into Group A, rats subjected to sham operation, and Group B, rats subjected to bile duct ligation (BDL). Three rats from each group were subsequently killed at different time points post-operatively (1, 5 and 10 days). As compared to sham-operated, BDL rats showed a gradual increase with time of superoxide radical in the intestine, liver, kidney and brain: for animals sacrificed on the 1^st, 5^th and 10^th day the increase was 45%, 50% and 96% in the liver, 76%, 81% and 118% in the intestine, 64%, 71% and 110% in the kidney and 76%, 95% and 142% in the brain, respectively. This study provides direct evidence of an early appearance of oxidative stress in diverse organs, implying a uniform systemic response to biliary obstruction and emphasizing the need of early bile flow restoration.     

血脂、血小板参数、HOMA-IR与阻塞性睡眠呼吸暂停低通气综合征合并高血压患者PSG参数的相关性及其预测价值研究

摘要 目的：探讨血脂、血小板参数、稳态模型胰岛素抵抗指数（HOMA-IR）与阻塞性睡眠呼吸暂停低通气综合征（OSAHS）合并高血压患者多导睡眠图（PSG）参数的相关性及其预测价值。方法：选择2020年1月至2022年11月徐州医科大学附属沭阳医院收治的163例OSAHS患者，根据是否合并高血压将其分为单纯OSAHS组（78例）及高血压组（85例），检测两组血脂、血小板参数、HOMA-IR、PSG参数；Pearson相关性分析血脂、血小板参数、HOMA-IR与PSG参数的相关性；多因素Logistic回归分析OSAHS合并高血压的危险因素；受试者工作特征（ROC）曲线分析血脂、血小板参数、HOMA-IR预测OSAHS合并高血压的价值。结果：高血压组甘油三酯（TG）、总胆固醇（TC）、低密度脂蛋白胆固醇（LDL-C）、平均血小板体积（MPV）、HOMA-IR、微觉醒指数（MAI）、呼吸暂停低通气指数（AHI）、氧减指数（ODI）高于单纯OSAHS组（P＜0.05），高密度脂蛋白胆固醇（HDL-C）水平低于单纯OSAHS组（P＜0.05）。高血压组TG、TC、LDL-C、MPV、HOMA-IR与MAI、AHI、ODI呈正相关（P＜0.05），HDL-C与MAI、AHI、ODI呈负相关（P＜0.05）。高体质量指数、高HOMA-IR及TG、MPV水平升高是OSAHS患者合并高血压的危险因素（P＜0.05）。联合TG、MVP、HOMA-IR预测OSAHS患者合并高血压的曲线下面积高于以上三指标单独预测。结论：OSAHS合并高血压患者TG、MPV水平及HOMA-IR显著增高，且与MAI、AHI、ODI呈正相关，TG、MPV、HOMA-IR联合检测对OSAHS患者合并高血压的预测价值较高。

摘要 目的：分析中重度阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的危险因素并构建其风险预测模型。方法：选取2017年1月～2021年1月我院接受多导睡眠监测（PSG）的97例OSAHS患者,根据PSG结果分为中重度组46例和轻度组51例。收集所有患者临床资料,采用单因素和多因素Logistic回归分析中重度OSAHS的危险因素和构建风险预测模型,受试者工作特征（ROC）曲线分析中重度OSAHS风险预测模型的应用价值。结果：单因素分析显示,中重度组男性、收缩压、舒张压、颈围、糖尿病、高血压、高血脂、Mallampati分级Ⅲ～Ⅳ级的比例和体质指数（BMI）、Epworth嗜睡量表（ESS）评分、C反应蛋白、血尿酸高于轻度组（P均＜0.05）。多因素Logistic回归分析显示,男性、糖尿病、高血压、改良Mallampati分级Ⅲ～Ⅳ级和BMI升高、C反应蛋白升高、血尿酸升高为中重度OSAHS的独立危险因素（P均＜0.05）。中重度OSAHS风险预测模型方程y=-12.558+0.950×性别+ 0.030×BMI+1.808×糖尿病+0.046×高血压+1.787×改良Mallampati分级+1.925×C反应蛋白+0.570×血尿酸。ROC曲线分析显示,该模型预测中重度OSAHS的曲线下面积（AUC）、敏感度、特异度分别为0.914（95％CI：0.839～0.961）、80.43％、90.20％。结论：男性、BMI升高、糖尿病、高血压、改良Mallampati分级Ⅲ～Ⅳ级、C反应蛋白升高、血尿酸升高是中重度OSAHS的危险因素,根据上述因素构建的预测模型对中重度OSAHS具有良好的预测价值。     

Sleepiness,inflammation and oxidative stress markers in middle-aged males with obstructive sleep apnea without metabolic syndrome: a cross-sectional study

Background

The simultaneous occurrence of metabolic syndrome and excessive daytime sleepiness are very common in obstructive sleep apnea (OSA) patients. Both conditions, if present in OSA, have been reported to be associated with inflammation and disruption of oxidative stress balance that impair the cardiovascular system. To verify the impact of daytime sleepiness on inflammatory and oxidative stress markers, we evaluated OSA patients without significant metabolic disturbance.

Methods

Thirty-five male subjects without diagnostic criteria for metabolic syndrome (Adult Treatment Panel III) were distributed into a control group (n = 10) (43 ± 10.56 years, apnea-hypopnea index - AHI 2.71 ± 1.48/hour), a non-sleepy OSA group (n = 11) (42.36 ± 9.48 years, AHI 29.48 ± 22.83/hour) and a sleepy OSA group (n = 14) (45.43 ± 10.06 years, AHI 38.20 ± 25.54/hour). Excessive daytime sleepiness was considered when Epworth sleepiness scale score was ≥ 10. Levels of high-sensitivity C-reactive protein, homocysteine and cysteine, and paraoxonase-1 activity and arylesterase activity of paraoxonase-1 were evaluated.

Results

Patients with OSA and excessive daytime sleepiness presented increased high-sensitivity C-reactive protein levels even after controlling for confounders. No significant differences were found among the groups in paraoxonase-1 activity nor arylesterase activity of paraoxonase-1. AHI was independently associated and excessive daytime sleepiness tended to have an association with high-sensitivity C-reactive protein.

Conclusions

In the absence of metabolic syndrome, increased inflammatory response was associated with AHI and daytime sleepiness, while OSA was not associated with abnormalities in oxidative stress markers.     

"三伏贴"对慢性阻塞性肺病系统炎症的影响

目的:观察"三伏贴"对稳定期慢性阻塞性肺疾病(COPD)患者系统炎症的影响,并评价其有效性。方法:收集稳定期慢性阻塞性肺疾病患者60例,按随机数字表随机分为"三伏贴"治疗组与安慰剂治疗组,每组30例;在常规西医治疗的基础上,分别给予"三伏贴"和安慰剂贴敷治疗,分别在入伏、初伏、中伏及末伏进行4次穴位贴敷,完成1疗程治疗者共56例。观察治疗前、1个疗程结束时、治疗后3个月、治疗后6个月血清炎症因子的变化。应用酶联免疫吸附试验(ELISA)检测血清白细胞介素-8(IL-8),免疫比浊法测定血清CRP,比较治疗前后两组间的炎症因子变化趋势,同时比较治疗前后两组间CAT评分(COPD assessment test,CAT)、呼吸困难评分(MRC)及生存质量评分。结果:"三伏贴"组、安慰剂组血清IL-8、CRP随时间变化趋势不同;其中试验组血清炎症因子随时间呈逐渐下降趋势,但治疗后6个月时炎症因子略有升高,而安慰剂组炎症因子水平呈逐渐升高趋势,治疗前试验组与安慰剂组炎症因子水平差异无统计学意义,治疗3个月后,两组患者IL-8、CRP水平差异即有统计学意义(P0.05)。试验组患者治疗后CAT评分、MRC评分较治疗前下降,生存质量评分升高,差异有统计学意义(P0.05),而安慰剂组患者在治疗后CAT评分、MRC评分较治疗前升高,差异有统计学意义(P0.05),生存质量评分下降,差异有统计学意义(P0.05)。同一时间点,试验组较安慰剂组CAT评分、MRC评分下降,生存质量评分明显升高,差异有统计学意义(P0.05)。结论:冬病夏治穴位敷帖可以改善COPD患者生存质量,缓解症状,其作用机理可能与降低系统炎症相关因子有关。
