Xiaolong Yu, Xuejia Song, Wenhai Sun, Shihua Zhao, Jiajun Zhao, Yan-Gang Wang
The incidence of papillary thyroid microcarcinoma (PTMC) has risen rapidly in recent years, and PTMC patients with central lymph node metastasis (CLNM) usually have poor prognosis. Independent risk factors predicting CLNM in PTMC have not been well understood. The aim of our study was to identify useful clinicopathological risk factors predicting CLNM in PTMC patients. This was a retrospective study of 917 patients with PTMC treated with surgery from January 2014 to December 2015 in our hospital. The relationship between clinicopathological factors and CLNM was analyzed to identify those factors predicting CLNM in PTMC...

This study investigated the usefulness of next-generation sequencing (NGS)-based single nucleotide polymorphism (SNP) haplotyping for preimplantation genetic diagnosis (PGD) of hemoglobin H (Hb H) disease. Multiple displacement amplification (MDA) was used for whole genome amplification (WGA) of biopsied trophectoderm (TE) cells. Gap-PCR and NGS-based SNP haplotyping was used to distinguish the two genotypes of -α(3.7)/αα and -(SEA)/αα for PGD of Hb H disease. One out of the ten blastocysts (B11) was successfully diagnosed as genotype -α(3...

STUDY QUESTION: Do human adult Leydig cells (ALCs) within hyperplastic micronodules display characteristics of foetal LCs (FLCs)? SUMMARY ANSWER: The gene expression profiles of FLCs and all ALC subgroups were clearly different, but there were no significant differences in expressed genes between the normally clustered and hyperplastic ALCs. WHAT IS KNOWN ALREADY: LCs are the primary androgen producing cells in males throughout development and appear in chronologically distinct populations; FLCs, neonatal LCs and ALCs...

BACKGROUND: Autotransplantation of frozen-thawed ovarian tissue is a method to preserve ovarian function and fertility in patients undergoing gonadotoxic therapy. In oncology patients, the safety cannot yet be guaranteed, since current tumor detection methods can only exclude the presence of malignant cells in ovarian fragments that are not transplanted. We determined the need for a novel detection method by studying the distribution of tumor cells in ovaries from patients with breast cancer...

Osteoarthritis (OA) is the most common form of arthritis and affects approximately one-third of people in the United Sates aged 65 years and older. Since 2013, the American Academy of Orthopaedic Surgeons has not been able to recommended using hyaluronic acid for patients with symptomatic OA of the knee. Subsequent publications have also cautioned against the use of viscosupplementation based on lack of efficacy and the potential for harm. We present a case of late hemorrhagic pseudoseptic arthritis encountered during TKA due to hyaluronic acid viscosupplementation...

Since Theodor Billroth and César Roux perfected the methods of postgastrectomy reconstruction in as early as the late nineteenth century, surgical management of gastric cancer has made incremental progress. The longstanding and contentious debate on the optimal extent of lymph node dissection for gastric cancer seems to have settled in favor of D2 dissection. Pylorus-preserving distal (central) gastrectomy has emerged as a less invasive, function-preserving option for T1N0 middle-third gastric cancers. Frozen section analysis of margins seems partially helpful in this direction...

Mycobacterium spp. infections are common in zebrafish kept in research facilities. These comorbidities can substantially modulate the responses of these fish to external and internal stimuli. Therefore, diagnostic tests to detect Mycobacterium spp. infections in zebrafish colonies prove essential. Here, we outline the development of quantitative simplex real-time PCR assays to detect the 3 Mycobacterium species most commonly identified in laboratory zebrafish. The assays targeted the heatshock protein 65 gene of M...

INTRODUCTION: We evaluate the clinical outcome of patients treated with conservative approach for small testicular masses (STMs). We analyzed the steps who brought to the selection of the therapeutic approach: starting from clinical presentation, through imaging and lab studies. METHODS: We considered 18 patients who underwent an organ-sparing approach for STMs from 2005 until 2014. The selection criteria were dimension of the mass and absence of clinical, laboratory and/or radiological malignancy suspicion...

PURPOSE: The function of the hip labrum during hip motion remains poorly known. Our hypothesis was that acetabular labrum will deform and change its shape during adduction to abduction movement consecutively to variation of strains passing from the acetabulum to the femoral head. An ex vivo anatomical study was conducted to analyse the morphological parameters variation of the mid-portion of the labrum (length, thickness, shape, deformation) as well as femoro-labral strains during hip adduction to abduction movement...

OBJECTIVE: A new mammalian tachykinin peptide encoded in a TAC4 gene was identified and designated as hemokinin-1 (HK-1). A representative of the tachykinin peptide family is substance P (SP), and the function of SP has been well characterized as a pain transmitter or modulator, while it is possible that HK-1 is involved in pruriceptive processing, but, as yet, the distribution of HK-1 peptide in the trigeminal sensory system is still unknown. Thus, the aim of the present study was to elucidate the distribution of HK-1, while comparing the expression of SP, in the trigeminal ganglion and trigeminal sensory nuclear complex...

Background. Lipiodol has been applied for decades in transarterial chemoembolization to treat liver malignancies, but its intrahepatic pathway through arterioportal shunt (APS) in the liver has not been histologically revealed. This rodent experiment was conducted to provide evidence for the pathway of Lipiodol delivered through the hepatic artery (HA) but found in the portal vein (PV) and to elucidate the observed unidirectional APS. Methods. Thirty rats were divided into 5 groups receiving systemic or local arterial infusion of red-stained iodized oil (RIO) or its hydrosoluble substitute barium sulfate suspension (BSS), or infusion of BSS via the PV, monitored by real-time digital radiography...

Accurate identification of prostate cancer in frozen sections at the time of surgery can be challenging, limiting the surgeon's ability to best determine resection margins during prostatectomy. We performed desorption electrospray ionization mass spectrometry imaging (DESI-MSI) on 54 banked human cancerous and normal prostate tissue specimens to investigate the spatial distribution of a wide variety of small metabolites, carbohydrates, and lipids. In contrast to several previous studies, our method included Krebs cycle intermediates (m/z <200), which we found to be highly informative in distinguishing cancer from benign tissue...

The intraoperative cytological assessment of bony resection margins (ICAB) is a feasible diagnostic approach to support frozen section for assessment of invasion of margins of soft and hard tissue. However, complex resection margins could challenge both diagnostic approaches. Our objective here was to identify the limitations of intraoperative diagnostic methods for assessing margins. We present an advanced cytological approach to assess complex margins that may solve the problem. Data from 119 patients in whom frozen section was supported by ICAB, were reviewed and the reasons for false results analysed...

PURPOSE: Although penile cancer (PC) only represents 1% of all male cancers, the traditional treatment of total or subtotal penectomy carries devastating psychological and functional outcomes. Organ sparing surgery (OSS) in PC is an attractive option if it can provide satisfactory cancer control equivocal or near equivocal to standard techniques. In fact, these techniques are meeting increasing acceptance. Accordingly, the need to evaluate these options objectively is crucial in a comprehensive review is timely in order to increase awareness of these procedures, their applicability and provide guidance to the practicing urologist...

PURPOSE: Mutation of the klotho gene in mice elicits a syndrome resembling accelerated human aging. However, there is limited evidence for the role of Klotho in the kidney. We conducted a comparative proteome analysis of wild-type (WT) and Klotho-knockout (kl(-/-) ) mouse kidneys to identify proteins involved in Klotho deficiency. EXPERIMENTAL DESIGN: MALDI-IMS of frozen kidney sections from 7-week-old male WT and kl(-/-) mice was used to determine genotype-specific differences in the MS distribution...
