Atypical Abnormal Pulmonary Vein Drainage with Atrial Septal Defect: Surgical Treatment

Sinus venosus atrial septal defect (SV‐ASD) usually coexists with partial anomalous pulmonary vein connection (PAPVC). It is a difficult diagnosis in transthoracic echocardiography (TTE) due to eccentric position of defects. We present a rare case of atypical anatomical variation in PAPVC, which was never described before. Two right pulmonary veins drained into superior vena cava, which overrode SV‐ASD and interatrial septum, a third pulmonary vein into the right atrium. Complete diagnosis could not be set after TTE, nor transesophageal echocardiography, whereas angio‐CT was finally conclusive. This diagnostic approach allowed the surgical planning.     

Chronic high-level multidrug-resistant Campylobacter coli enterocolitis in an agammaglobulinemia patient: Oral gentamicin efficacy

BackgroundCampylobacter is the most common cause of infectious diarrhea in agammaglobulinemia patients. These infections can be severe, prolonged, and recurrent in such patients.Patient and methodsWe report a 29-year-old male patient with X-linked agammaglobulinemia with Campylobacter coli enterocolitis that persisted for nine months despite multiple 10- to 14-day courses of oral ciprofloxacin and azithromycin.ResultsThe isolate was highly resistant to ciprofloxacin, erythromycin, tetracycline, and fosfomycin. The patient failed to respond to intravenous ertapenem, 1.0 g/day for two weeks, to which the pathogen was susceptible. He was finally cured with oral gentamicin, 80 mg four times daily, and stool cultures remained negative during the seven-month follow-up.ConclusionOral aminoglycoside might be the most appropriate choice for eradication of persistent Campylobacter in the intestinal tract for macrolide- and fluoroquinolone-resistant isolate in agammaglobulinemia patients with chronic diarrhea or relapsing systemic infections.     

维生素D与多囊卵巢患者胰岛素抵抗相关性及其机制研究

目的:探讨维生素D对多囊卵巢综合征(PCOS)患者胰岛素抵抗(IR)的影响及其机制研究.方法:选取自2013年2月～2014年2月在该院就诊的48例PCOS患者作为PCOS组,另选30例健康育龄期妇女作为对照组,测量研究者身高、体质量参数,计算体质指数(BMI),采用全自动生化分析仪葡萄糖氧化酶检测空腹血糖浓度(FBG)、化学发光法检测血清空腹胰岛素(FI)及胰岛素样生长因子-1(IGF-1)水平、ELISA方法测定血清25-(OH)D3浓度,计算稳态胰岛素评价指数(HOMA-IR)用于评价胰岛素抵抗性,量化胰岛素敏感指数(QUICKI)用于评价胰岛素敏感度,并分析FI、HOMA-IR、QUICKI及IGF-1与血清25-(OH)D3浓度的相关性.结果:PCOS组BMI及FBG与对照组相比,差异无统计学差异(P＞0.05),而FI、HOMA-IR、QUICKI、25-(OH) D3及IGF-1与对照组比较,差异均有统计学差异(P＜0.05);并且PCOS组FI和HOMA-IR与血清25-(OH)D3浓度呈显著负相关,差异有统计学意义(P＜0.05),QUICKI和IGF-1水平与血清25-(OH)D3浓度呈显著正相关,差异有统计学意义(P＜0.05).结论:PCOS患者IR可能与血清中维生素D缺乏有关,而IGF-1分泌减少又可能是导致PCOS患者维生素D缺乏的重要原因.     

妇科腹腔镜围手术期碳水化合物口服疗法对术后胰岛素抵抗影响的研究

目的观察妇科腹腔镜手术围术期碳水化合物口服疗法和传统禁饮食方案两种不同的临床处理措施对于术后胰岛素抵抗（IR）的影响。 方法选取2018年2月至8月入住徐州医科大学附属医院妇科，行腹腔镜下全子宫切除手术的非糖尿病患者共98例，将采用围术期碳水化合物口服疗法者作为观察组（50例），采用传统禁饮食方案者作为对照组（48例）。检测所有病例的术前、术后第1天及第3天的空腹血糖（FPG）及空腹胰岛素（FINS），并利用稳态模式评估法计算稳态模型胰岛素抵抗指数（HOME-IR）。对于观察组与对照组患者术前、术后第1天和术后第3天的FPG、FINS和HOME-IR等指标，组间比较采用独立样本t检验。两组患者术后腹胀、术后24 h通气、术后发热的发生情况的比较采用确切概率法检验。 结果观察组与对照组比较，术前和术后第1天FPG差异无统计学意义（P均>0.05），术后第3天FPG明显降低［（4.34±0.59）mmol/L vs （4.96±0.64）mmol/L］，差异有统计学意义（t=-4.96，P=0.002）。观察组与对照组比较，术前和术后第1天FINS差异无统计学意义（P均>0.05），术后第3天FINS明显降低［（45.39±13.55）mIU/L vs （51.18±9.34） mIU/L］，差异有统计学意义（t=-2.46，P=0.033）。观察组与对照组比较，术前HOME-IR差异无统计学意义（P>0.05），术后第1天和术后第3天HOME-IR明显降低［（13.08±4.80）vs （15.03±4.11）；（9.37±3.65）vs （11.30±2.55）］，差异有统计学意义（t=-0.69，P=0.042；t=-3.99，P=0.033）。两组患者术后其他观察指标比较，观察组术后24 h通气率与对照组比较明显增高（76.0% vs 64.6%），差异有统计学意义（P=0.045）。两组患者在术后腹胀、术后发热的发生率方面差异无统计学意义（P均>0.05）。两组患者均未发生术中误吸。 结论妇科腹腔镜手术围术期应用碳水化合物口服疗法较传统禁饮食方案，能有效减轻术后IR程度，促进术后康复进程，且不增加围术期并发症的发生率。

血吸虫病是一种严重危害人类健康、影响社会经济发展的重大传染病,为全球公共卫生负担和危害最严重的被忽视的热带病之一。吡喹酮是20世纪70年代研制出的一种高效、低毒、价廉的广谱抗蠕虫口服药,为世界卫生组织（WHO）推荐的抗血吸虫的首选药物。吡喹酮在血吸虫病流行区现场大规模反复使用已超过40年,血吸虫是否会对吡喹酮产生抗药性引起国际社会极大担忧,为学术界关注的热点科学问题。针对血吸虫病防治中这一重大需求,自1996年起, 在国家科技支撑计划、国家自然科学基金、江苏省自然科学基金等项目基金资助下,我们在血吸虫病流行区现场和实验室,对血吸虫在吡喹酮药物的压力是否会产生抗药性、抗性虫株的生物学特性、抗性的检测、吡喹酮抗性的交叉抗药性及抗药性的预防和控制等科学问题进行较为系统的研究,本文就其研究及其意义作一概述。     

The effects of carnitine supplementation on clinical characteristics of patients with non-alcoholic fatty liver disease: A systematic review and meta-analysis of randomized controlled trials

ObjectiveThe beneficial effects of carnitine supplementation on nonalcoholic fatty liver disease are unclear. We conducted a systematic review and meta-analysis to evaluate the effects of carnitine supplementation on liver function, lipid profile, body mass index, body weight, and homeostasis model assessment of insulin resistance in patients with nonalcoholic fatty liver disease.MethodsA comprehensive search of PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar databases were performed. Only randomized placebo-controlled human studies that examined the effects of carnitine supplementation on liver function, lipid profile, body mass index, body weight, and homeostasis model assessment of insulin resistance up to September 2019 were included. Fixed effects or random-effects models were applied to compute the pooled effect size. Heterogeneity assessments were performed using Cochran’s Q test and I-squared statistics. The quality of the studies was assessed using the Jaded scale.ResultsA total of 5 articles were selected, including 334 individuals (167 in control and 167 in intervention groups). The results demonstrated that carnitine supplementation significantly reduced homeostasis model assessment of insulin resistance (HOMA-IR) (WMD: −0.91; 95 % CI: −1.11, −0.72; p < 0.001, I² = 0.0 %) and the levels of aspartate aminotransferase (AST) (WMD: −16.62; 95 % CI: −28.11, −5.14; IU/l; p = 0.005, I² = 93.5 %), alanine aminotransferase (ALT) (WMD: -33.39; 95 % CI: −45.13, −21.66; IU/l; p < 0.001, I² = 93.4 %), and triglycerides (TG) (WMD: −22.13; 95 % CI: −38.91, −5.34; mg/dl; p = 0.01; I² = 0.0 %). However, the results of the pooled effect size did not show any significant effect of carnitine supplementation on body mass index (BMI) (WMD: 0.07; 95 % CI: −0.15, 0.29; p = 0.55; I² = 0.0 %), body weight (WMD: −0.28; 95 % CI: −2.23, 1.68; p = 0.78; I² = 45.7 %), the levels of gamma-glutamyl transferase (γGT) (WMD: −11.31; 95 % CI: −24.35, 1.73; IU/l; p = 0.09, I² = 61.1 %), cholesterol (WMD: −13.58; 95 % CI: −46.77, 19.60; mg/dl; p = 0.42; I² = 94.9 %), high-density lipoprotein-cholesterol (HDL-C) (WMD: 1.36; 95 % CI: −0.96, 3.68; mg/dl; p = 0.25; I² = 64.7 %), and low density lipoprotein-cholesterol (LDL-C) (WMD: −14.85; 95 % CI: −45.43, 15.73; mg/dl; p = 0.34; I² = 96.4 %).ConclusionsThis analysis shows that carnitine supplementation for patients with nonalcoholic fatty liver disease demonstrates a reduction in AST, ALT, TG levels and HOMA-IR. However, no significant effect of carnitine supplementation was observed on BMI, body weight, the levels of γGT, TC, HDL-cholesterol and LDL-cholesterol.
