Abstract
BACKGROUND A few studies have reported only short-term outcomes of various robotic and laparoscopic liver resection types; however, published data in left lateral sectionectomy (LLS) have been limited. The aim of this study was to compare the long- and short-term outcomes of robotic and laparoscopic LLS. METHODS We retrospectively compared demographic and perioperative data as well as postoperative outcomes of robotic (n = 12) and laparoscopic (n = 31) LLS performed between May 2007 and July 2013. Resection indications included malignant tumors (n = 31) and benign lesions (n = 12) including intrahepatic duct (IHD) stones (n = 9). RESULTS There were no significant differences in perioperative outcomes of estimated blood loss, major complications, or lengths of stay, but operating time was longer in robotic than in laparoscopic LLS (391 vs. 196 min, respectively) and the operation time for IHD stones did not differ between groups (435 vs. 405 min, respectively; p = 0.190). Disease-free (p = 0.463) and overall (p = 0.484) survival of patients with malignancy did not differ between groups. The 2- and 5-year disease-free survival rates were 63.2 and 36.5 %, respectively. However, robotic LLS costs were significantly higher than laparoscopic LLS costs ($8183 vs. $5190, respectively; p = 0.009). CONCLUSIONS Robotic LLS was comparable to laparoscopic LLS in surgical outcomes and oncologic integrity during the learning curve. Although robotic LLS was more expensive and time intensive, it might be a good option for difficult indications such as IHD stones.

Abstract
BACKGROUNDS/AIMS Laparoscopic cholecystectomy can reduce postoperative pain and recovery time. However, some patients experience prolonged postoperative hospital stay. We aimed to identify factors influencing the postoperative hospital stay after laparoscopic cholecystectomy. METHODS Patients (n=336) undergoing laparoscopic cholecystectomy for gallbladder pathology at 8 hospitals were enrolled and divided into 2 groups: 2 or less and more than 2 days postoperative stay. Perioperative factors and patient factors were retrospectively analyzed. RESULTS The patient population median age was 52 years, and consisted of 32 emergency and 304 elective operations. A univariate analysis of perioperative factors revealed significant differences in operation time (p<0.001), perioperative transfusion (p=0.006), emergency operation (p<0.001), acute inflammation (p<0.001), and surgical site infection (p=0.041). A univariate analysis of patient factors revealed significant differences in age (p<0.001), gender (p=0.036), diabetes mellitus (p=0.011), preoperative albumin level (p=0.024), smoking (p=0.010), and American Society of Anesthesiologists score (p=0.003). In a multivariate analysis, operation time (p<0.001), emergency operation (p<0.001), age (p=0.014), and smoking (p=0.022) were identified as independent factors influencing length of postoperative hospital stay. CONCLUSIONS Operation time, emergency operation, patient age, and smoking influenced the postoperative hospital stay and should be the focus of efforts to reduce hospital stay after laparoscopic cholecystectomy.

Abstract
BACKGROUND When bile duct cancer recurs after surgery, treatment options are limited. This study examines the usefulness of reoperative pancreaticoduodenectomy for recurrent cancer after initial segmental bile duct resection. METHODS Six patients (5 males, 1 females; median age 65 years) who underwent pancreaticoduodenectomy for recurrent remnant bile duct cancer following segmental bile duct resection were included: 4 underwent surgery at Severance Hospital and 2 at Gangnam Severance Hospital from January 2000 to December 2013. Medical records data were retrospectively reviewed, including demographics, type of first and second surgery, radicality of resection, TNM stage, adjuvant treatments, complications, and survival. Kaplan-Meier curves were used to analyze survival. RESULTS The median interval between operations was 57 (range 7-95) months. Median operation time was 6.9 (range 5.2-12.8) h, blood loss was 400 (range 50-1170) mL, intensive care unit stay was 1 (range 1-2) day, and postoperative hospital stay was 33 (range 15-55) days. No patient died. Four had severe complications. The median survival after pancreaticoduodenectomy was 16 (range 5-89) months. Four patients had recurrence. T stage, N stage, and resection radicality influenced survival. CONCLUSION Pancreaticoduodenectomy is reasonable for recurrent remnant bile duct cancer following segmental bile duct resection, particularly for patients with no distant metastasis, locally confined recurrence, and good general condition.

Abstract
Backgrounds/Aims Although laparoscopic cholecystectomy is a common and widely accepted technique, the use of prophylactic antibiotics in elective laparoscopic cholecystectomy still remains controversial. The aim of this study is to determine whether prophylactic antibiotics could prevent surgical site infection after elective laparoscopic cholecystectomy and to identify any risk factors for surgical site infection. Methods This study included 471 patients undergoing laparoscopic cholecystectomy between January 2009 and May 2012. Period 1 patients (279) received second generation cephalosporin 1 g intravenously after induction of anesthesia, and Period 2 patients (192) were not given prophylactic antibiotics. The characteristics and surgical site infections of the patients were compared and analyzed. Results The overall rate of surgical site infection was 1.69% for the total of 471 patients. The incidence of surgical site infection was similar for the two Periods: 5 of 279 patients (1.79%) in Period 1, 3 of 192 patients (1.56%) in Period 2 (p=0.973). All of the patients with surgical site infections were well treated under conservative treatments without any sequelae. The preoperative albumin level (p=0.023) contributed to surgical site infection. Conclusions Prophylactic antibiotics are not necessary for elective laparoscopic cholecystectomy but patients in poor nutritional state with low albumin level should consider prophylactic antibiotics.

Abstract
Knowledge of the precise rigidity dependence of the helium flux is important in understanding the origin, acceleration, and propagation of cosmic rays. A precise measurement of the helium flux in primary cosmic rays with rigidity (momentum/charge) from 1.9 GV to 3 TV based on 50 million events is presented and compared to the proton flux. The detailed variation with rigidity of the helium flux spectral index is presented for the first time. The spectral index progressively hardens at rigidities larger than 100 GV. The rigidity dependence of the helium flux spectral index is similar to that of the proton spectral index though the magnitudes are different. Remarkably, the spectral index of the proton to helium flux ratio increases with rigidity up to 45 GV and then becomes constant; the flux ratio above 45 GV is well described by a single power law.

Abstract
BACKGROUND Lymph node (LN) metastasis is an important prognostic factor in gallbladder cancer (GBCA). LN status has been adopted as a critical element of staging systems. However, the influence of total lymph node count (TLNC) remains unclear. We determined the optimal minimum TLNC and compared the prognostic significance of LN status indices in GBCA. METHODS We retrospectively reviewed medical records of 128 patients with T2 or greater GBCA who underwent LN dissection. We analyzed overall survival (OS) and relevance of the number of metastatic LNs, ratio of metastatic LNs to retrieved LNs (LNR), and TLNC in predicting OS. RESULTS The median OS durations were 120, 35, and 18 months in T2, T3, and T4 GBCA. Five-year OS rates were 73%, 43%, and 0% in T2, T3, and T4 GBCA. LN status did not significantly impact OS in T2 or T4 GBCA. However, all LN indices were significantly correlated with OS in T3 GBCA. Furthermore, multivariate analysis revealed that a metastatic LN count of more than four and a TLNC of more than eight were independent prognostic factors of OS in T3 GBCA. CONCLUSIONS TLNC and the number of positive LNs may be more important prognostic factors than LNR in T3 GBCA. Additionally, accurate staging may not be achieved in cases of T3 GBCA if the total number of retrieved LNs is less than eight. Thus, to ensure proper staging, we recommend that surgeons harvest more than eight LNs in patients with T3 GBCA.

Abstract
In this work, we propose a practical method that can combine the two functionalities of dental panoramic and cone-beam CT (CBCT) features in one by using a single panoramic detector. We implemented a CS-based reconstruction algorithm for the proposed method and performed a systematic simulation to demonstrate its viability for 3D dental X-ray imaging. We successfully reconstructed volumetric images of considerably high accuracy by using a panoramic detector having an active area of 198.4 mm × 6.4 mm and evaluated the reconstruction quality as a function of the pitch (p) and the angle step (Δθ). Our simulation results indicate that the CS-based reconstruction almost completely recovered the phantom structures, as in CBCT, for p≤2.0 and θ≤6°, indicating that it seems very promising for accurate image reconstruction even for large-pitch and few-view data. We expect the proposed method to be applicable to developing a cost-effective, volumetric dental X-ray imaging system.

Abstract
Background Neonatal meningitis-causing Escherichia coli (NMEC) is the predominant Gram-negative bacterial pathogen associated with meningitis in newborn infants. High levels of heterogeneity and diversity have been observed in the repertoire of virulence traits and other characteristics among strains of NMEC making it difficult to define the NMEC pathotype. The objective of the present study was to identify genotypic and phenotypic characteristics of NMEC that can be used to distinguish them from commensal E. coli. Methods A total of 53 isolates of NMEC obtained from neonates with meningitis and 48 isolates of fecal E. coli obtained from healthy individuals (HFEC) were comparatively evaluated using five phenotypic (serotyping, serum bactericidal assay, biofilm assay, antimicorbial susceptibility testing, and in vitro cell invasion assay) and three genotypic (phylogrouping, virulence genotyping, and pulsed-field gel electrophoresis) methods. Results A majority (67.92 %) of NMEC belonged to B2 phylogenetic group whereas 59 % of HFEC belonged to groups A and D. Serotyping revealed that the most common O and H types present in NMEC tested were O1 (15 %), O8 (11.3 %), O18 (13.2 %), and H7 (25.3 %). In contrast, none of the HFEC tested belonged to O1 or O18 serogroups. The most common serogroup identified in HFEC was O8 (6.25 %). The virulence genotyping reflected that more than 70 % of NMEC carried kpsII, K1, neuC, iucC, sitA, and vat genes with only less than 27 % of HFEC possessing these genes. All NMEC and 79 % of HFEC tested were able to invade human cerebral microvascular endothelial cells. No statistically significant difference was observed in the serum resistance phenotype between NMEC and HFEC. The NMEC strains demonstrated a greater ability to form biofilms in Luria Bertani broth medium than did HFEC (79.2 % vs 39.9 %). Conclusion The results of our study demonstrated that virulence genotyping and phylogrouping may assist in defining the potential NMEC pathotype.

Abstract
Background Cancer stem cells (CSCs) constitute 1–2 % of cancer tissue and are a major cause of tumor metastasis and recurrence. The culture environment is important in maintaining CSCs in vitro. Sphere formation is one method of culturing CSCs. In this study, we identified and validated optimal culture conditions for sphere formation in hepatocellular carcinoma cells. Methods Huh7 and HepG2 cells were plated in three different media types and were allowed to form spheres. To confirm the pluripotency of sphere cells, the expression of stem cell markers was evaluated. EpCAM, Connexin 32, and Connexin 43 expression was evaluated using reverse transcription-polymerase chain reaction (RT-PCR). The expression of E-cadherin, β-catenin, CD90, and CD133 was evaluated using immunocytochemistry. Flow cytometry was performed to confirm the presence of stem cell markers CD133 and Connexin 32. Results Cells maintained in medium containing growth factors ((DMEM(+))GF) showed greater cell proliferation than cells in media with fetal bovine serum (FBS) (DMEM(+)FBS) or without FBS (DMEM(−)FBS). Cells cultured in DMEM(+)FBS medium exhibited greater proliferation after 20 days in culture than cells cultured under the other two conditions. Cells cultured in DMEM(−)FBS medium did not proliferate; therefore, this condition was removed from further analysis. RT-PCR and flow cytometry showed that sphere-forming cells cultured in DMEM(+)GF and DMEM(+)FBS media had similar expression of stem cell markers. Conclusion Therefore, growth factor-free medium is an adaptable, efficient, and cost-effective tool for in vitro cultivation of CSCs.

Abstract
Purpose This study analyzed the outcomes of patients with resected extrahepatic bile duct cancer (EHBDC) in order to clarify the role of adjuvant treatments in these patients. Materials and Methods A total of 336 patients with EHBDC who underwent curative resection between 2001 and 2010 were analyzed retrospectively. The treatment types were as follows: surgery alone (n=168), surgery with chemotherapy (CTx, n=90), surgery with radiotherapy (RT) alone (n=29), and surgery with chemoradiotherapy (CRT, n=49). Results The median follow-up period was 63 months. The 5-year rates of locoregional failure-free survival (LRFFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) for all patients were 56.5%, 59.7%, 36.6%, and 42.0%, respectively. In multivariate analysis, surgery with RT and CRT was a significant prognostic factor for LRFFS, and surgery with CTx was a significant prognostic factor for DMFS, and surgery with CTx, RT, and CRT was a significant prognostic factor for PFS (p < 0.05). Surgery with CTx and CRT showed association with superior OS (p < 0.05), and surgery with RT had marginal significance (p=0.078). In multivariate analysis of the R1 resection patients, surgery with CRT showed significant association with OS (p < 0.05). Conclusion Adjuvant RT and CTx may be helpful in improving clinical outcomes of patients with resected EHBDC who have a high risk of disease recurrence, particularly R1 resection patients. Conduct of additional prospective, larger-scale studies will be required in order to confirm the benefit of adjuvant RT and CTx in these patients.

Abstract
UNLABELLED Activin A, which is a signaling molecule similar to Nodal, rapidly promotes endoderm induction of both embryonic stem (ES) cells and MSCs. Protocols for hepatic induction exhibit differences in efficiency and reproducibility depending on the specific methods or sources of MSCs. We characterized the effects of Activin A concentration on induction efficiency during hepatic differentiation of MSCs. Human MSCs (hMSCs) were differentiated into a hepatic lineage via a three-step protocol. Cells were first cultured in fetal bovine serum-free MSCs conditioned medium supplemented with Activin A (20, 50, or 100 ng/mL) for 3 days followed by treatment with additional agents. RT-PCR analysis, immunocytochemistry assays, periodic acid and Schiff's solution staining, and ELISAs were performed to confirm hepatic induction of hMSCs. Expression of genes related to the primitive foregut endoderm was observed in cells treated with higher concentration of Activin A. Gene expression related to functional primitive hepatocytes was observed in the early phases of hepatic differentiation. During the early period of the differentiation protocol, greater albumin secretion was observed when cells were treated with higher concentrations of Activin A. CONCLUSION Thus, Activin A concentration affects the rate of endoderm induction of hMSCs, and at higher concentrations in vitro.

Lee JG, Bak SY, Nahm JH, Lee SW, Min SO, Kim KS. Toward angiogenesis of implanted bio-artificial liver using scaffolds with type I collagen and adipose tissue-derived stem cells. KOREAN JOURNAL OF HEPATO-BILIARY-PANCREATIC SURGERY 2015; 19:47-58. [PMID: 26155277 PMCID: PMC4494077 DOI: 10.14701/kjhbps.2015.19.2.47] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/02/2015] [Revised: 05/25/2015] [Accepted: 05/28/2015] [Indexed: 12/01/2022]
Abstract
Backgrounds/Aims Stem cell therapies for liver disease are being studied by many researchers worldwide, but scientific evidence to demonstrate the endocrinologic effects of implanted cells is insufficient, and it is unknown whether implanted cells can function as liver cells. Achieving angiogenesis, arguably the most important characteristic of the liver, is known to be quite difficult, and no practical attempts have been made to achieve this outcome. We carried out this study to observe the possibility of angiogenesis of implanted bio-artificial liver using scaffolds. Methods This study used adipose tissue-derived stem cells that were collected from adult patients with liver diseases with conditions similar to the liver parenchyma. Specifically, microfilaments were used to create an artificial membrane and maintain the structure of an artificial organ. After scratching the stomach surface of severe combined immunocompromised (SCID) mice (n=4), artificial scaffolds with adipose tissue-derived stem cells and type I collagen were implanted. Expression levels of angiogenesis markers including vascular endothelial growth factor (VEGF), CD34, and CD105 were immunohistochemically assessed after 30 days. Results Grossly, the artificial scaffolds showed adhesion to the stomach and surrounding organs; however, there was no evidence of angiogenesis within the scaffolds; and VEGF, CD34, and CD105 expressions were not detected after 30 days. Conclusions Although implantation of cells into artificial scaffolds did not facilitate angiogenesis, the artificial scaffolds made with type I collagen helped maintain implanted cells, and surrounding tissue reactions were rare. Our findings indicate that type I collagen artificial scaffolds can be considered as a possible implantable biomaterial.

Abstract
BACKGROUND We performed this study to define distinctive clinical features of leiomyosarcoma by assessing prognostic factors. METHODS Between 1988 and 2011, 129 leiomyosarcoma patients who underwent surgical resection with curative intent were retrospectively reviewed. RESULTS Of the 129 leiomyosarcoma patients, the distribution of anatomic locations was: extremity (n = 25), pelvis (n = 40), thoracic cavity (n = 11), intra-abdomen (n = 19), retroperitoneum (n = 23), and head/neck (n = 11). We classified the anatomic locations into two categories as abdominal (intra-abdomen and retroperitoneum, n = 42) and extra-abdominal (extremity, pelvis, thoracic cavity, and head/neck, n = 87). Prognosis was worse for the abdominal group than for the extra-abdominal group (median DFS 2.9 9.0 years, P = 0.04). Similarly, overall survival (OS) was also significantly worse for abdominal group (P = 0.027). Independent prognostic factors for survival were primary site (P = 0.041, hazard ratio (HR) 1.7; 95 % CI 1.2-2.8), tumor size (P = 0.038, HR 1.9; 95 % CI 1.13-3.38), margin status (P = 0.019, HR 2.1; 95 % CI 1.13-3.88), and histology grade (P = 0.01, HR 3.59; 95 % CI 1.64-7.87). We identified four different risk groups with different survival outcome: group 1 (n = 8), no adverse factors; groups 2 (n = 37) and 3 (n = 61) with one and two adverse factors, and group 4 (n = 23) with 3 or 4 adverse factors. CONCLUSION Primary site, tumor size, resection margin, and histology subtype were independently associated with survival outcome. A prognostic model for leiomyosarcoma patients revealed four distinct groups of patients with good prognostic discrimination.

Abstract
AIMS The purpose of this study was to investigate the effect of Lactobacillus casei variety rhamnosus (LCR35) on Atopic dermatitis (AD)-like symptoms in mice. METHODS AND RESULTS AD-like skin lesions in BALB/C mice were induced by sensitization and subsequent repeated challenges with trimellitic anhydride (TMA) for 10 days. LCR35 was orally administered to the mice once daily throughout the study. In the TMA-induced AD model, orally administered LCR35 suppressed significantly irritant-related scratching behaviour and skin dehydration as well as apparent severity of AD. LCR35 also significantly decreased serum levels of IgE and IL-4, but not IFN-γ, implying the restoration of TMA-induced disruption of Th1/Th2 balance. Quantitative real-time PCR targeting hypervariable regions of 16S rDNA gene of faecal microbiota indicated that the LCR35 treatment increased the population of Bifidobacterium, Lactobacilli, Enterococcus and Bacteroides fragilis group, but decreased those of Clostridium coccoides group. CONCLUSIONS LCR35 has the ability to suppress the development of AD in mice, possibly through the modulation of Th1/Th2 balance and gut microbiota. SIGNIFICANCE AND IMPACT OF THE STUDY LCR35 has a strong potential as a probiotic for preventing AD.

Abstract
OBJECTIVE To assess the image quality and dosimetric effects of the Philips orthopaedic metal artefact reduction (OMAR) (Philips Healthcare System, Cleveland, OH) function for reducing metal artefacts on CT images of head and neck (H&N) patients. METHODS 11 patients and a custom-built phantom with metal bead inserts (alumina, titanium, zirconia and chrome) were scanned. The image was reconstructed in two ways: with and without OMAR (OMAR and non-OMAR image). The mean and standard deviation values of CT Hounsfield unit (HU) for selected regions of interest of each case were investigated for both images. Volumetric modulated arc therapy plans were generated for all cases. Gamma analysis of each dose distribution pair in the patient (1%/1 mm criteria) and phantom (2%/2 mm and 3%/3 mm criteria) images was performed. The film measurements in phantom for two metal beads were conducted for evaluating the calculated dose on both OMAR and non-OMAR images. RESULTS In the OMAR images, noise values were generally reduced, and the mean HU became closer to the reference value (measured from patients without metal implants) in both patient and phantom cases. Although dosimetric difference was insignificant for the eight closed-mouth patients (γ = 99.4 ± 0.5%), there was a large discrepancy in dosimetric calculation between OMAR and non-OMAR images for the three opened-mouth patients (γ = 91.1%, 94.8% and 96.6%). Moreover, the calculated dose on the OMAR image is closer to the real delivered dose on a radiochromic film than was the dose from the non-OMAR image. CONCLUSION The OMAR algorithm increases the accuracy of CT HU and reduces the noise such that the entire radiation treatment planning process can be improved, especially for contouring and segmentation. ADVANCES IN KNOWLEDGE OMAR reconstruction is appropriate for the radiotherapy planning process of H&N patients, particularly of patients who use a bite block.

Abstract
A precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1 GV to 1.8 TV is presented based on 300 million events. Knowledge of the rigidity dependence of the proton flux is important in understanding the origin, acceleration, and propagation of cosmic rays. We present the detailed variation with rigidity of the flux spectral index for the first time. The spectral index progressively hardens at high rigidities.

Abstract
The genus Jeffersonia, which contains only two species, has a trans-Atlantic disjunct distribution. The aims of this study were to determine the requirements for breaking dormancy and germination of J. dubia seeds and to compare its dormancy characteristics with those of the congener in eastern North America. Ripe seeds of J. dubia contain an underdeveloped embryo and were permeable to water. In nature, seeds were dispersed in May, while embryos began to grow in September, and were fully elongated by late November. Germination started in March of the next year, and seeds emerged as seedlings soon after germination. In laboratory experiments, incubation at high temperatures (25 °C, 25/15 °C) for at least 8 weeks was required to initiate embryo growth, while a transfer to moderate temperatures (20/10 °C, 15/6 °C) was needed for the completion of embryo growth. At least 8 weeks at 5 °C was effective in overcoming physiological dormancy and for germination in seeds after the embryos had fully elongated. Thus, both high and low temperatures were essential to break dormancy. Gibberellic acid (GA3 ) treatment could substitute for the high temperature requirement, but not for the low temperature requirement. Based on the dormancy-breaking requirements, it is confirmed that the seeds have deep simple morphophysiological dormancy. This dormancy type is similar to that of seeds of the eastern North American species J. diphylla. Although seeds require 10-11 months from seed dispersal to germination in nature, under controlled conditions they required only 3 months after treatment with 1000 mg·l(-1) GA3 , followed by incubation at 15/6 °C. This represents practical knowledge for propagation of these plants from seed.

Abstract
OBJECTIVES Seniors, during their senescence, experience difficulties when engaging in physical, social, and leisure activities. Meanwhile, increased access to information technology in recent years among seniors has led to the increased applicability of games aiding senior activities that incorporate information technology. In this study, we constructed and assessed a nursing intervention incorporating an actual walking exercise game developed for the use of seniors in order to identify the cognitive, social, and physical impact it has on their health behaviors. SUBJECTS AND METHOD This quasi-experimental study used a one-group pre-/post-test design in which 15 people 65 years of age or older were selected to participate through a serious health game conducted at the senior welfare center twice a week, for 12 weeks. Besides having their basic physical measurements taken, seniors participated in physical exercise sessions that included educational content. The measured variables were health beliefs and concerns, subjective knowledge, subjective norms, perceived reliability, perceived ease of use and usefulness, perceived behavioral control, attitudes about health behaviors, intentions to perform health behaviors, health behaviors, blood pressure, pulse rate, endurance, agility and balance, and flexibility. RESULTS Significant increases in health beliefs and concerns, perceived reliability, perceived behavioral control, perceived ease of use, attitudes about health behaviors, and intentions to perform health behaviors were observed at post-test, compared with pre-test data points. These increases were also recorded for physical domains. Significant increases in systolic blood pressure and pulse rates were noted immediately after the intervention, along with increased endurance levels, indicating that the exercise had an effect on participants' health. CONCLUSIONS Ongoing research is required regarding the development and impact of distinctive nursing interventions, conducted through various forms of serious health games relatively easy to use, by integrating various motivating factors for engaging in health behaviors and the entertainment value of such games.

Abstract
INTRODUCTION To investigate the association between pregnancies with small for gestational age (SGA) neonates and the concentration of cell-free fetal DNA or cell-free total DNA in maternal plasma during the first and second trimesters using tissue-specific epigenetic characteristics of the SERPINB5 gene. METHODS A nested case-control study was conducted with maternal plasma collected at 11 to 26 gestational weeks from 51 women with SGA neonates and 102 controls. We performed a real-time quantitative methylation-specific PCR to quantify concentrations of unmethylated-SERPINB5 (U-SERPINB5) as a cell-free fetal DNA marker and methylated-SERPINB5 (M-SERPINB5) as a cell-free total DNA marker. RESULTS A positive correlation was observed between U-SERPINB5 and M-SERPINB5 concentrations in both control (r = 0.363, p < 0.001) and SGA groups (r = 0.548, p < 0.001). Moreover, the concentration of U-SERPINB5 or M-SERPINB5 was significantly positive correlated with gestational age at sampling in both controls (U-SERPINB5: r = 0.397, p < 0.001; M-SERPINB5: r = 0.275, p = 0.005) and SGA (U-SERPINB5: r = 0.274, p = 0.052; M-SERPINB5: r = 0.439, p = 0.001). However, the concentration of U-SERPINB5 or M-SERPINB5 was not correlated with birthweight. At 11-14 weeks, U-SERPINB5 and M-SERPINB5 concentrations in SGA did not differ significantly from those of controls. There were also no statistically significant differences in the concentrations of U-SERPINB5 and M-SERPINB5 between SGA and controls at 15-26 weeks of gestation. DISCUSSION Our findings suggest that U-SERPINB5 and M-SERPINB5 concentrations in maternal plasma during early pregnancy are not associated with pregnancies who delivered SGA neonates.
