Choroideremia is a rare X-linked disorder causing progressive chorioretinal atrophy. Affected patients develop night blindness with progressive peripheral vision loss and eventual blindness. Herein, we report two Korean families with choroideremia. Multimodal imaging studies showed that the probands had progressive loss of visual field with characteristic chorioretinal atrophy, while electroretinography demonstrated nearly extinguished cone and rod responses compatible with choroideremia. Sanger sequencing of all coding exons and flanking intronic regions of the CHM gene revealed a novel small deletion at a splice site (c...

Chinese herbal medicine (CHM) formulas are the major components of traditional Chinese medicine (TCM) interventions. The general reporting quality of randomized controlled trials (RCTs) of CHM formulas is disappointing, although CONSORT (Consolidated Standards of Reporting Trials) Statement extensions for herbal medicinal interventions and acupuncture interventions are available. A group of TCM clinical experts, methodologists, epidemiologists, and editors has developed this CONSORT Extension for CHM Formulas (CONSORT-CHM Formulas 2017) through a comprehensive process, including publication of the draft version, solicitation of comments, revision, and finalization...

BACKGROUND: Deletions in Xq21 cause various congenital defects in males including choroideremia, deafness and mental retardation, depending on their size and gene content. Until now only a limited number of patients with Xq21 deletions has been reported. CASE PRESENTATION: Here we describe a 17-year-old male with choroideremia, deafness, and mental retardation syndrome. Using SNP arrays, an 8.05 Mb deletion in Xq21 was identified inherited from the apparently healthy mother...

The present study aimed to evaluate the expression and localization of chondromodulin‑I (ChM‑I) in human osteoarthritic cartilage and its correlation with vascular invasion during osteoarthritis (OA) progression. Osteochondral specimens were collected from patients with OA, as well as from young and aged donors without joint diseases. The grade and the number of vascular channels terminating in non‑calcified cartilage of these collected specimens were assessed by Safranin‑O/Fast green staining. ChM‑I expression in articular cartilage was examined by immunohistochemistry, western blotting and reverse transcription‑quantitative polymerase chain reaction analyses...

OBJECTIVE: Viral oral ulcers are common presentations in pediatric clinics. Although self-limiting, painful ulcerative lesions and inflamed mucosa can decrease oral intake and lead to dehydration. Despite the widespread use of Chinese herbal medicine (CHM) for pediatric upper respiratory disease in Taiwan, there is little evidence for its effectiveness as an antipyretic or in aiding ulcer healing for children with viral oral ulcers. We report two cases of children who presented with viral oral ulcers to illustrate the potential efficacy of CHM treatment in recovery from herpangina (HA) and herpetic gingivostomatitis (HGS)...

Background: Although the morphological features characteristic of products of conception specimens including molar pregnancies are well described, substantial histopathological similarities are observed between the different entities, especially in cases of early pregnancies. Furthermore, there are no current solid criteria that could predict cases with progression to persistent gestational trophoblastic disease. In this study, we aimed to determine the most specific histopathological and immunohistochemical features required for accurate diagnosis that can reliably predict the clinical behavior...

Cardiac hematological malignancies (CHMs) are rare entities and comprise lymphoma, leukemic infiltration, and extramedullary manifestation of multiple myeloma. The aim of this work is to summarize typical growth patterns, imaging features, and outcome parameters of CHM. Overall, 12 cases from 4 centers were reviewed retrospectively together with 604 cases from the literature. Cardiac hematological malignancies were mainly represented by B-cell lymphoma (70.0%). Other entities were rarer. Almost half of the patients showed involvement of multiple cardiac structures...

We studied the significance of new blood vessels in the pathogenesis of temporomandibular joint osteoarthritis (TMJOA). Fifteen 8-week-old female Sprague-Dawley rats were selected to establish TMJOA models of gradually induced occlusal disorders. Five rats were sacrificed at 4, 8 and 16 weeks, and histological exam was conducted along with micro-computed tomography observation on the condyle specimen. The distribution and number of new blood vessels breaking were observed through the tidemark through CD34 immunofluorescence staining...

Smart drug carrier with function-oriented adaptations is highly desired due to its unique properties in medical applications. Herein, adaptive chitosan hollow microspheres (CHM) are fabricated by employing interfacial Schiff-base bonding reaction. Hydrophilic macromolecules of glycol chitosan are fixed at the oil/water interface through numerous hydrophobic small molecules of borneol 4-formylbenzoate, forming the CHM with a positively charged surface and lipophilic cavity. These CHM have an average size of 400-1000 nm after passing through the 0...

PURPOSE OF REVIEW: Although much has been written to define the phenotype and genotype of choroideremia (CHM), research continues to provide new insights that serve to better understand its pathogenesis and the directions for potential experimental therapies. RECENT FINDINGS: We would like to highlight new findings, expanding the type of disease-causing mutations to include mutations in the CHM promoter that will dramatically influence gene expression. Information derived from careful phenotyping of patients points increasingly to the central role of the retinal pigment epithelium as the key cell layer affected in the degenerative process...

This paper provides a review of the most recent works in machine olfaction as applied to the identification of Chinese Herbal Medicines (CHMs). Due to the wide variety of CHMs, the complexity of growing sources and the diverse specifications of herb components, the quality control of CHMs is a challenging issue. Much research has demonstrated that an electronic nose (E-nose) as an advanced machine olfaction system, can overcome this challenge through identification of the complex odors of CHMs. E-nose technology, with better usability, high sensitivity, real-time detection and non-destructive features has shown better performance in comparison with other analytical techniques such as gas chromatography-mass spectrometry (GC-MS)...

DNA genotyping is the gold standard diagnostic test to distinguish hydatidiform moles from nonmolar but morphologically abnormal products of conception (POC). The test is based on comparison of alleles at 15 short tandem repeat loci in the chorionic villi of the POC to those in the maternal decidual tissue. If alleles in the POC are not present in the decidua, then the most concerning interpretation is that the POC has a paternal uniparental genome diagnostic of a complete hydatidiform mole (CHM). However, a nonmolar pregnancy from a donated egg would also appear the same because the maternal genome of the POC would match that of the maternal donor, not that of the decidua of the individual carrying the pregnancy...

In order to achieve the comprehensive quality control of Chinese herbal medicine (CHM), the conventional practice of selecting a single marker for testing has been gradually replaced by the determination of multiple active components based on the characteristics of the synergistic interaction of CHM and applicability of sophisticated analytical techniques. However, with a huge number of CHM in the market and more complex preparations, the limited availability of various standard substances for quantitative analysis has been a major bottleneck in realizing the goal...

Aberrant signaling transduction induced by mutant KRAS proteins occurs in 20∼30% of non-small cell lung cancer (NSCLC), however, a direct and effective pharmacological inhibitor targeting KRAS has not yet reached the clinic to date. Honokiol, a small molecular polyphenol natural biophenolic compound derived from the bark of magnolia trees, exerts anticancer activity, however, its mechanism remains unknown. In this study, we sought to investigate the in vitro effects of honokiol on NSCLC cell lines harboring KRAS mutations...
