The activity of free radicals in follicular fluid was related to ovarian responsiveness, in vitro fertilization (IVF), and embryo transfer success rate. However, studies analyzing the relationship between the free radical scavenging capacity and embryo quality of infertile women with polycystic ovarian syndrome (PCOS) were lacking. The aim of this study was to evaluate the relationship between the free radical scavenging window of women with PCOS and their embryo quality. The free radical scavenging capacity of follicular fluid from women with PCOS was determined by a,a-diphenyl-b-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) assay, superoxide radical, and reactive oxygen species (ROS) assay. In the DPPH and ROS assays, the follicular fluid from grades I and II embryos was significantly higher than the follicular fluid from grades III and IV embryos. The lower control limit of DPPH radical scavenging capacity and upper control limit of ROS level were 13.2% and 109.0 cps, respectively. The calculated lower control limit and upper control limit were further confirmed in the follicular fluid of embryos of all grades. These cut-off values of free radical scavenging activity of follicular fluid could assist embryologists in choosing the development of embryos in PCOS patients undergoing IVF.

遗传因素、生活方式和环境因素与多囊卵巢综合征（PCOS）的发生相关。身体质量指数（BMI）的增加会加剧生殖及代谢障碍，降低PCOS女性的生育能力。本文对在中国大陆21个研究中心开展的一项大样本、多中心、随机对照试验进行二次分析。共有1000名PCOS女性参加本试验。其中，998名PCOS女性被纳入分析。BMI增加与月经失调加剧、高睾酮水平、高代谢综合征患病率以及生活质量降低相关。BMI正常组、超重组和肥胖组的女性人均排卵率分别为83.0%、78.2%和63.6%（P < 0.001），活产率分别为23.6%、18.1%和15.3%（P = 0.030）。与中国南方的PCOS患者相比，北方的PCOS患者生殖结局较差，血糖和血脂代谢不良，运动量少，以及总排卵率更低（81.2% vs 74.8%，绝对差：6.4%，95%置信区间：1.2%~11.5%）。结果显示，中国南北方的汉族PCOS女性具有典型的表型特征。与生活在中国南方的女性相比，在同样的干预措施下，中国北方的女性BMI更高，糖脂代谢障碍更严重，临床结局更差。表型特征及排卵的差异可以通过BMI差异加以解释。

The increased levels of intracellular reactive oxygen species (ROS) in granulosa cells (GCs) may affect the pregnancy results in women with polycystic ovary syndrome (PCOS). In this study, we compared thein vitro fertilization and embryo transfer (IVF-ET) results of 22 patients with PCOS and 25 patients with tubal factor infertility and detected the ROS levels in the GCs of these two groups. Results showed that the PCOS group had significantly larger follicles on the administration day for human chorionic gonadotropin than the tubal factor group (P<0.05); however, the number of retrieved oocytes was not significantly different between the two groups (P>0.05). PCOS group had slightly lower fertilization, cleavage, grade I/II embryo, clinical pregnancy, and implantation rates and higher miscarriage rate than the tubal factor group (P>0.05). We further found a significantly higher ROS level of GCs in the PCOS group than in the tubal factor group (P<0.05). The increased ROS levels in GCs caused GC apoptosis, whereas NADPH oxidase 2 (NOX2) specific inhibitors (diphenyleneiodonium and apocynin) significantly reduced the ROS production in the PCOS group. In conclusion, the increased ROS expression levels in PCOS GCs greatly induced cell apoptosis, which further affected the oocyte quality and reduced the positive IVF-ET pregnancy results of women with PCOS. NADPH oxidase pathway may be involved in the mechanism of ROS production in GCs of women with PCOS.

促排卵是多囊卵巢综合征（PCOS）不孕症的一线治疗方案。卵巢对促排卵治疗的排卵应答差被认为与胰岛素抵抗和高雄激素血症相关。在一个包含1000名PCOS不孕妇女（PCOSAct）的前瞻性队列中，我们开展了一项全外显子联合靶向单核苷酸多态性（SNP）测序以及代谢组学研究。在全基因组水平找出与无排卵显著相关的常见变异和罕见突变，并通过机器学习算法构建排卵预测模型。研究发现，ZNF438基因中标记为rs2994652 (p=2.47×10–8)的常见变异和REC114基因中的一个罕见功能突变（rs182542888，p=5.79×10–6）与促排卵治疗失败显著相关。携带rs2994652 A等位基因和REC114 p.Val101Leu (rs182542888)的PCOS不孕妇女进行促排卵治疗的总排卵率更低（分别为：比值比 （OR）=1.96，95% 置信区间（CI）[1.55~2.49]；OR=11.52，95% CI [3.08~43.05]），出现排卵的间隔时间更长（平均56.7天vs.49.0天，p<0.001；78.1天vs.68.6天，p=0.014）。对于rs2994652突变者，L-苯丙氨酸水平升高并与胰岛素抵抗稳态模型（HOMA-IR）指数（r=0.22, p=0.05）和空腹血糖（r=0.33, p=0.003）呈正相关；对于rs182542888突变者，花生四烯酸代谢产物水平下降并与升高的抗苗勒管激素（r=－0.51, p=0.01）和总睾酮（r=－0.71, p=0.02）呈负相关。整合基因变异位点、代谢产物及临床特征的联合预测模型可提高对排卵的预测能力[曲线下面积（AUC）=76.7%]。ZNF438基因的一个常见变异和REC114基因的一个罕见功能突变，以及与二者相关的苯丙氨酸和花生四烯酸代谢物改变，与PCOS女性不孕症的促排卵治疗失败相关。

Aneurysmal dilatation of the aortic sinuses of Valsalva has been most extensively documented in the setting of aortopathies, particularly Marfan syndrome. On the other hand, there is limited data in the literature about congenital sinus of Valsalva aneurysms outside this context. For the purpose of this review, we carried out a literature search on aneurysmal dilatation of the sinuses of Valsalva in Marfan syndrome, and compared this with congenital sinus of Valsalva aneurysms, also including data from a case series from our institution. In conclusion, there are differences in management of aortic dilatation in Marfan syndrome and congenital sinus of Valsalva aneurysms. Though less well-recognised, congenital aneurysms are often associated with significant morbidity and mortality and timely intervention is necessary.

Bronchiolitis obliterans syndrome (BOS) after hematopoietic stem cell transplantation (HSCT) is a major cause of morbidity and mortality with limited treatment options. Lung transplantation (LTX) has been rarely reported as a treatment option for selected HSCT recipients with this problem. In the present study, we reported six patients who underwent LTX due to BOS after HSCT (two females, four males) from January 2012 to December 2014 in our center. The median time from HSCT to diagnosis of BOS was 2.5 years (ranging from 1 to 5 years). At a median time of 4 years (ranging from 2 to 5 years) after diagnosis of BOS, four patients received bilateral sequential LTX, and two patients received single LTX. One of the recipients suffered from mild acute rejection after LTX, another suffered from primary lung graft dysfunction on post-operation day 2, and three experienced fungal infections. The median time for follow-up after LTX was 19.5 months (ranging from 12 to 39 months). At present, all patients are alive with good functional capacity and no relapse of BOS and hematologic malignancy conditions. Patients who received bilateral LTX have better pulmonary functions than patients who received single LTX.

Nephrotic syndrome (NS) is one of the most common glomerular diseases with signs of nephrosis, heavy proteinuria, hypoalbuminemia, and edema. Dysfunction of glomerular filtration barrier causes protein loss through the kidneys. Focal segmental glomerulosclerosis (FSGS) accounts for nearly 20% of NS among children and adults. Adult-onset FSGS/NS is often associated with low response to steroid treatment and immunosuppressive medication and poor renal survival. Several genes involved in NS and FSGS have been identified by linkage analysis and next-generation sequencing. Most of these genes encode proteins and are highly expressed in glomerular podocytes, which play crucial roles in slit-diaphragm signaling, regulation of actin cytoskeleton dynamics and maintenance of podocyte integrity, and cell–matrix interactions. In this review, we focus on the recently identified genes in the adult-onset NS and FSGS and discuss clinical significance of screening of these genes.

Cushing’s syndrome (CS) during pregnancy is a rare condition with significant maternal and fetal complications. A case of CS during the third trimester of pregnancy secondary to adrenocortical adenoma was reported. Literature review revealed the disadvantages of different treatments in this period. Besides the conservative treatment, surgery is recommended for CS during the third trimester of pregnancy secondary to adrenal adenoma, if an experienced surgeon is available.

Familial amyloid cardiomyopathy is a challenging condition that mimics many other diseases, particularly in patients with pronounced neurological presentations and unexplained or equivocal cardiac abnormalities. In this case, a 57-year-old man was admitted for outpatient cardiological evaluation of progressive right heart failure and limb paraesthesias. The patient presented with hypertension, chronic Guillain-Barre syndrome, and sick sinus syndrome. Transthoracic echocardiograms showed a thickened ventricular wall and enlarged atrium. Tissue Doppler showed a restrictive filling pattern. Transthyretin (TTR)-associated amyloidosis, which was revealed by abdominal fat-pad biopsy and DNA analysis, explained the concurrence of independent pathological features, including neuropathy and cardiac involvement. Genetic testing identified a G>T mutation in exon 4 of the transthyretin (TTR) gene. This mutation resulted in the alanine-to-serine substitution at amino acid position 117. Moreover, genetic testing confirmed that the patient’s asymptomatic son carried the same amyloidogenic TTR mutation. Given these findings, the diagnosis of familial amyloid cardiomyopathy, which was misdiagnosed as chronic Guillain-Barre syndrome, was proposed.

The emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012 brought back memories of the occurrence of severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002. More than 1500 MERS-CoV cases were recorded in 42 months with a case fatality rate (CFR) of 40%. Meanwhile, 8000 cases of SARS-CoV were confirmed in six months with a CFR of 10%. The clinical presentation of MERS-CoV ranges from mild and non-specific presentation to progressive and severe pneumonia. No predictive signs or symptoms exist to differentiate MERS-CoV from community-acquired pneumonia in hospitalized patients. An apparent heterogeneity was observed in transmission. Most MERS-CoV cases were secondary to large outbreaks in healthcare settings. These cases were secondary to community-acquired cases, which may also cause family outbreaks. Travel-associated MERS infection remains low. However, the virus exhibited a clear tendency to cause large outbreaks outside the Arabian Peninsula as exemplified by the outbreak in the Republic of Korea. In this review, we summarize the current knowledge about MERS-CoV and highlight travel-related issues.

Zinc (Zn) is an essential mineral that is required for various cellular functions. Zn dyshomeostasis always is related to certain disorders such as metabolic syndrome, diabetes and diabetic complications. The associations of Zn with metabolic syndrome, diabetes and diabetic complications, thus, stem from the multiple roles of Zn: (1) a constructive component of many important enzymes or proteins, (2) a requirement for insulin storage and secretion, (3) a direct or indirect antioxidant action, and (4) an insulin-like action. However, whether there is a clear cause-and-effect relationship of Zn with metabolic syndrome, diabetes, or diabetic complications remains unclear. In fact, it is known that Zn deficiency is a common phenomenon in diabetic patients. Chronic low intake of Zn was associated with the increased risk of diabetes and diabetes also impairs Zn metabolism. Theoretically Zn supplementation should prevent the metabolic syndrome, diabetes, and diabetic complications; however, limited available data are not always supportive of the above notion. Therefore, this review has tried to summarize these pieces of available information, possible mechanisms by which Zn prevents the metabolic syndrome, diabetes, and diabetic complications. In the final part, what are the current issues for Zn supplementation were also discussed.
