To investigate the gene mutation in a pedigree with X-linked ichthyosis (XLI) and to explore the relationship between the mutation and its clinical manifestations, genomic DNA of affected members, the normal member of the pedigree and 50 unrelated normal members was extracted with a whole blood genomic DNA extraction kit and the DNA was used as a template for the polymerase chain reaction (PCR)-mediated amplification of exon 1 and exon 10 of the STS gene. hHb6 (human hair basic keratin) gene was used as the internal control. Our results showed that the STS gene was deleted in affected members in the pedigree with X-linked ichthyosis. The normal member of the pedigree and 50 unrelated normal members had no such deletion. The proband and his mother had products in the internal control after PCR amplification. The blank control had no product. It is concluded that deletion of the STS gene existed in this pedigree with X-linked ichthyosis, and it is responsible for the unique skin lesions of X-linked ichthyosis.

OBJECTIVETo investigate the impact of novel P2Y(12) receptor inhibitors including prasugrel or ticagrelor on platelet reactivity in patients with acute coronary syndrome (ACS) receiving percutaneous coronary intervention (PCI), and provide clinical data for novel oral P2Y(12) receptor inhibitors use among Chinese patients.

METHODSBetween October 2011 to February 2014, 174 consecutive patients (135 males; (67.8±11.8) years old) with ACS undergoing PCI in Kiang Wu Hospital, Macau were prospectively enrolled in this study. Oral aspirin and one P2Y(12) receptor inhibitor were administered for 5 days or above after PCI, patients were divided into clopidogrel, prasugrel and ticagrelor groups in accordance with the agent administered. Platelet reactivity of the patients was detected by VerifyNow P2Y(12) reaction unit (PRU); and the high on-treatment platelet reactivity (HPR) and non-HPR were defined as PRU≥208 and PRU<208 respectively. Patients with HPR during clopidogrel therapy were switched either to prasugrel or ticagrelor, or continued the same treatment; and then the platelet reactivity was monitored again.

RESULTSThere were 113 clopidogrel cases (64.9%), 20 prasugrel cases (11.5%) and 41 ticagrelor cases (23.6%). Fifty-seven cases (32.8%) were defined as HPR post P2Y(12) receptor inhibitor use, in which 55 cases (55/113, 48.7%) were treated with clopidogrel. The degree of inhibition of platelet reactivity was significantly different in patients on clopidogrel, prasugrel and ticagrelor therapy, percent inhibition assayed by the VerifyNow P2Y(12) system was 28.2%±23.5%, 61.4%±26.7% and 81.3%±19.8% respectively (P<0.05). Different degree of platelet reactivity was achieved by the 3 P2Y(12) receptor inhibitors at multiple time points. The among-group differences in platelet reactivity became apparent at the early treatment stage (P<0.05). Platelet aggregation decreased significantly in patients switched from clopidogrel to prasugrel or ticagrelor (P<0.05).

CONCLUSIONNovel oral P2Y(12) receptor inhibitors are more effective in inhibiting platelet reactivity in ACS patients, and our results show that novel oral P2Y(12) receptor inhibitors provide a new option for ACS patients with HPR post clopidogrel or high-risk features of ischemic complications, including stent thrombosis and post-PCI ischemic events.

Current treatment of vitiligo is still a great challenge, since most cases of vitiligo have variable re-pigmentation outcomes due to their unpredictable responses to existing therapeutic regimens. There is an urgent need to identify this re-pigmentation process and to develop novel therapies. This review illustrates the most current research and latest understanding of vitiligo skin re-pigmentation and related regulatory mechanisms. Literature was collected from PubMed until January 2020, using the search terms including "vitiligo," "re-pigmentation," "phototherapy," "narrow-band ultraviolet B, " "excimer," "fractional carbon dioxide laser," and "melanocyte stem cells." Literature was mainly derived from English articles. Article type was not limited. Emerging evidence suggests that patients with vitiligo present various re-pigmentation patterns following ultraviolet B phototherapy, which relies on different cell reservoirs from the perilesional margins and/or from uninvolved hair follicles to replenish functional melanocytes that are lost in vitiliginous skin. The following events are likely to be involved in this re-pigmentation process, including: 1) changes in the paracrine secretion and distribution of transforming growth factor-β1 in the bulge area and in the epidermis; 2) the enhanced transfer of dermal pro-melanogenic growth factors to the epidermis; and 3) the induction of a C-X-C motif chemokine ligand (CXCL) 12-enriched micro-environment that efficiently recruits CXCR4- or CXCR7-positive melanocytes. Ongoing studies on the cellular and molecular events underlying vitiligo re-pigmentation will help design new therapeutic strategies to improve treatment outcomes.

Background/Aims: Growing evidence suggests a negative effect of eosinophilic esophagitis (EoE) on patients’ general health-related quality of life (HRQOL). However, the relevance and use of coping strategies and its relation to (disease specific) HRQOL as well as its determinants have not been studied well. Methods: Adult EoE patients were invited to complete standardized measures on general HRQOL (Short Form-36 Health Survey [SF-36]) and coping strategies (Utrechtse Coping Lijst [UCL]). Scores were compared to general population norms. The disease specific Adult Eosinophilic Esophagitis Quality of Life (EoE-QOL-A) measure was used to assess EoE-HRQOL. Socio-demographic-and clinical factors were also evaluated. Results: In total, 147 adult EoE patients (61% males), age 43 (interquartile range, 29-52) years were analyzed. Mental health-scores (SF-36) were significantly lower in EoE patients, whereas physical health-scores (SF-36) were similar in EoE patients (vs the general population;P = 0.010 and P = 0.240), respectively. The subdomain “disease anxiety” (EoE-QOL-A) was mostly affected, determinants were; female gender, younger age, severe clinical disease activity, higher number of food bolus extraction, and more recent EoE-diagnosis. Less effective coping styles (ie, passive/palliative reaction) were associated with a significant impact on each individual EoE-HRQOLsubdomain as well as lower scores of the Mental Health Component Scale in male EoE patients. Passive reaction in female EoEpatients correlated with impairment of the EoE-HRQOL-domains “emotional impact” and “disease anxiety.” Active problem solving was significantly related to better perception of mental HRQOL (SF-36) in both males and females. Conclusions EoE has a significant negative impact on mental HRQOL, with less effective coping strategies––specifically in males, being a relevant determinant. Thus, a pro-active approach towards coping mechanisms is needed in order to enhance HRQOL and manage patients’ burden of EoE.

In the past few years, the bone field has witnessed great advances in genome-wide association studies (GWASs) of osteoporosis, with a number of promising genes identified. In particular, meta-analysis of GWASs, aimed at increasing the power of studies by combining the results from different study populations, have led to the identification of novel associations that would not otherwise have been identified in individual GWASs. Recently, the first whole genome sequencing study for osteoporosis and fractures was published, reporting a novel rare nonsense mutation. This review summarizes the important and representative findings published by December 2013. Comments are made on the notable findings and representative studies for their potential influence and implications on our present understanding of the genetics of osteoporosis. Potential limitations of GWASs and their meta-analyses are evaluated, with an emphasis on understanding the reasons for inconsistent results between different studies and clarification of misinterpretation of GWAS meta-analysis results. Implications and challenges of GWAS are also discussed, including the need for multi- and inter-disciplinary studies.

Chewing lice (Phthiraptera) that parasitize the globally threatened swan goose Anser cygnoides have been long recognized since the early 19th century, but those records were probably biased towards sampling of captive or domestic geese due to the small population size and limited distribution of its wild hosts. To better understand the lice species parasitizing swan geese that are endemic to East Asia, we collected chewing lice from 14 wild geese caught at 3 lakes in northeastern Mongolia. The lice were morphologically identified as 16 Trinoton anserinum (Fabricius, 1805), 11 Ornithobius domesticus Arnold, 2005, and 1 Anaticola anseris (Linnaeus, 1758). These species are known from other geese and swans, but all of them were new to the swan goose. This result also indicates no overlap in lice species between older records and our findings from wild birds. Thus, ectoparasites collected from domestic or captive animals may provide biased information on the occurrence, prevalence, host selection, and host-ectoparasite interactions from those on wild hosts.
