Abstract
BACKGROUND Vulvovaginal candidiasis (VVC) is frequent in women of reproductive age, but very limited data are available on the epidemiology in cases of VVC in China. OBJECTIVES The current study has been conducted to reveal the prevalence, species distribution of yeast causing VVC and molecular genetics of Candida albicans in China. METHODS Vaginal swabs were collected from 543 VVC outpatients recruited in 12 hospitals in China between September 2017 and March 2018. They were preliminarily incubated on Sabouraud dextrose agar and then positive subjects of which were then transmitted to our institute for further identification. CHROMagar™ was used to isolate Candida species, and all isolates were finally identified by DNA sequencing. Multilocus sequence typing (MLST) was used to analyse phylogenetic relationships of the various C. albicans isolates. RESULTS Eleven different yeast species were identified in 543 isolates, among which C. albicans (84.7%) was the most frequent, followed by C. glabrata (8.7%). We obtained 117 unique diploid sequence types from 451 clinical C. albicans isolates and 92 isolates (20.4%) belonged to a New Clade. All the strains appearing in the New Clade were from northern China and they were isolated from non-recurrent VVC. CONCLUSIONS Our findings suggest that C. albicans are still the main cause of VVC in China and the majority of C. albicans isolates belongs to Clade 1 with DST 79 and DST 45 being two most common. Moreover, the New Clade revealed in our study seems to be specific to northern China.

Abstract
BACKGROUND Obesity and overweight are significant public health problems because of higher risk for coronary artery disease (CAD). It is very important to determine new predictive markers to identify the CAD risk in obese and overweight. To aim this, we analysed HDL-C subgroups (HDL2-C and HDL3-C) and their paraoxonase-1 (PON-1) activity in obese, overweight and normal weight subjects. METHOD 71 obese, 40 overweight and 30 healthy subjects as a control group were enrolled the study. Serum lipids levels were determined with enzymatic colorimetric method. Further, PON-1 activities and HDL-C levels were determined by spectrophotometric methods. Non-HDL3-C concentrations were calculated with the subtraction of HDL3-C from total HDL-C. RESULTS The mean serum levels of total HDL-C, HDL3-C, Non-HDL3-C and ApoA1 were higher in control group than obese and overweight groups. There were a statistically significant difference between obese and control group in terms of Lp(a), hsCRP and HOMA index. Higher total PON-1, non-HDL3 PON-1 and HDL3 PON-1 activities were found in the control group compared with obese and overweight groups. Total HDL was weakly negative correlated with the HOMA index, BMI and waist circumference. There was a weak negative correlation between non-HDL3-C and waist circumference. CONCLUSION Altered HDL-subgroups pattern and decreased PON-1 activities may cause increased risk for CVD in obese and overweight individuals. Therefore determination of HDL subgroups and their PON-1 activity may improve risk prediction compared with measuring total HDL-C levels and its PON-1 activity alone. Body weight and insulin resistance appear to have a role in the decreased HDL-C levels and PON-1activity in obese. Further studies should be conducted to shed more light on impacts of these markers in CVD.

Abstract
The transcription factor scleraxis (SCX) is expressed throughout tendon development and plays a key role in directing tendon wound healing. However, little is known regarding its role in fetal or young postnatal tendons, stages in development that are known for their enhanced regenerative capabilities. Here we used RNA-sequencing to compare the transcriptome of adult and fetal tenocytes following SCX knockdown. SCX knockdown had a larger effect on gene expression in fetal tenocytes, affecting 477 genes in comparison to the 183 genes affected in adult tenocytes, indicating that scleraxis-dependent processes may differ in these two developmental stages. Gene ontology, network and pathway analysis revealed an overrepresentation of extracellular matrix (ECM) remodelling processes within both comparisons. These included several matrix metalloproteinases, proteoglycans and collagens, some of which were also investigated in SCX knockdown tenocytes from young postnatal foals. Using chromatin immunoprecipitation, we also identified novel genes that SCX differentially interacts with in adult and fetal tenocytes. These results indicate a role for SCX in modulating ECM synthesis and breakdown and provide a useful dataset for further study into SCX gene regulation.

Abstract
Background/aim This retrospective study aimed to investigate the clinical profile of pituitary insufficiency (PI) in adult population. Materials and methods One hundred and fifty patients who were diagnosed as having PI between 2012 and 2018 (53.3% female, mean age 48.13 ± 15.83 years) were retrospectively analyzed. Results Age at diagnosis was higher in females as compared with males (51.13 ± 15.95 vs. 44.70 ± 15.08 years, P = 0.012). The most frequent presenting signs were headache (29.4%) and visual disturbance (19.6%) in general. Females frequently presented with headache (33.3%), whereas males presented with sexual dysfunction (34.4%). The most frequent cause of PI was nonfunctional pituitary adenoma (28.8%) in general population. A frequent cause of PI was Sheehan’s syndrome (33.8%) among females and nonfunctional pituitary adenoma (38.6%) among males. Pituitary macroadenoma (75.8%) was frequent in pituitary tumors with PI. 55.3 % of the patients had 4 pituitary hormones deficiencies and 26.0% of patients had 3 pituitary hormones deficiencies. Gonadotropin deficiency was the leading pituitary hormone deficiency. The frequency of posttraumatic PI was 4.7% in the general population. Conclusion Nonfunctional pituitary adenoma was the most common cause of PI among males and Sheehan’s syndrome was a major etiologic factor in females. Sheehan’s syndrome remains an important health problem in Turkey although obstetric care has improved. Posttraumatic PI should be considered in the differential diagnosis of idiopathic PI.

Abstract
The association of the FTO gene and HNF1α gene on gestational diabetes mellitus (GDM) and preeclampsia remains unclear. This is the first study to examine whether HNF1α gene and FTO gene were associated with having GDM and preeclampsia in Turkish women. Healthy pregnant women (n = 101) and women with GDM (n = 169) were included. GDM was divided into two groups as GDM-only (n = 90) and GDM-preeclampsia (n = 79). Genotyping of HNF1α gene p.I27L, p.A98V, and p.S487N, and FTO gene rs9939609 SNPs were performed using RT-PCR. The frequency of p.S487N, p.A98V, and FTO genotype were similar between the groups (p > .05). p.I27L GG-wild, GT, and TT genotype were 56.5%, 36.6%, and 6.9% in controls; 40.0%, 51.1%, and 8.9% in GDM-only; and 26.6%, 51.9%, and 21.5% in GDM-preeclampsia (p = .034). TT and GT genotype was more frequent in GDM-preeclampsia than in controls (p < .05). GT genotype was increased in GDM-only compared with controls (p < .05). TT genotype was more frequent in GDM-preeclampsia than in GDM-only (p < .05). p.I27L TT genotype was independently associated with increased blood pressure (BP) and urinary protein. p.I27L TT genotype was associated with increased preeclampsia risk in patients with GDM by increasing BP and urinary protein.

Abstract
Abstract
Background
Right atrial (RA) deformation by two-dimensional speckle tracking echocardiography has a relatively new technique to evaluate right heart function with pulmonary hypertension and cardiomyopathy. Reproducibility between observers of this technique is important to develop into a robust and reliable tool. Experience may pose significant challenges.
Purpose
The aim of this study is to evaluate reproducibility of RA strain (global and regional) between novice and expert.
Methods
One hundred thirty-three patients (n = 133) underwent 2D-Speckle tracking derived RA strain analysis by 3 independent blinded readers (expert and 2 novices). The novice observers were medical interns with no prior experience in performing strain analysis. Echocardiographic images were acquired from iE33 (Philips Medical System) but were analysed offline using single vendor dependent software (QLAB version 11.0; Philips Medical System). The result of novice observer was calculated by the average of novice observers. RA strain parameters were assessed: global RA strain and segmental (Basal, Mid, Roof). Intraobserver and interobserver analyses were performed using intra class correlation coefficients (ICC) between expert and novice.
Results
Expert and novice observer demonstrated good interobserver reproducibility of global RA strain (ICC 0.88) and segmental parameters (Basal: ICC 0.89, Mid: ICC 0.87, Roof: ICC 0.84). Of all parameters, the basal segment of RA strain showed the greatest interobserver agreement. Intraobserver agreement for novice observer was excellent for global RA strain and segmental parameters (ICC > 0.88).
Conclusions
Global RA strain and segmental parameters were highly reproducible by novice and expert strain observer.

Abstract
Background Parathyroidectomy has ameliorated cardiovascular risk factors in patients with hypercalcemic primary hyperparathyroidism (PHPT), but the effect of parathyroidectomy on normocalcemic PHPT is not exactly known. This case-controlled study aimed to investigate the effect of parathyroidectomy on cardiovascular risk factors in patients with normocalcemic and hypercalcemic PHPT. Methods Subjects with normocalcemic PHPT (n = 35), age- and sex-matched hypercalcemic PHPT (n = 60) and age- and sex-matched control (n = 60) were included. Cardiometabolic disorders were investigated with traditional cardiometabolic risk factors and the Framingham cardiovascular risk score (CRS) before and 6 months after parathyroidectomy. Results Diabetes, dyslipidemia, hypertension, obesity, insulin resistance, osteoporosis, having fractures were similarly increased in the hypercalcemic and normocalcemic PHPT groups (p > 0.05) compared with the controls (p < 0.05). Blood pressures, glucose metabolism (glucose, insulin, HOMA-IR) and lipid profiles were similarly increased in the PHPT groups (p > 0.05) compared with the controls (p < 0.05). After parathyroidectomy, blood pressures, serum total cholesterol, and HOMA-IR were decreased in both PHPT groups (p < 0.05). CRS was lower in the controls (5.74 ± 3.24, p < 0.05). After parathyroidectomy, CRS was decreased in the normocalcemic (11.98 ± 10.11 vs. 7.37 ± 4.48) and hypercalcemic (14.62 ± 11.06 vs. 8.05 ± 7.72) PHPT groups. Increased blood pressures were independent predictors of serum iPTH. Conclusion The normocalcemic and hypercalcemic PHPT groups had similarly increased cardiovascular risk factors, even independently of serum calcium. Parathyroidectomy ameliorated the increased cardiovascular risk factors in both normocalcemic and hypercalcemic PHPT.

Abstract
Nodular thyroid disease is a very common disorder in patients with acromegaly. Insulin-like growth factor-1 (IGF-1) is a thyroid growth factor, and there is a correlation between IGF-1 levels and thyroid volume (TV) in patients with acromegaly. There is no study investigating the impact of somatostatin analog (SSA) treatment on thyroid nodule volume in patients with acromegaly. We aimed to assess thyroid nodule volume change with SSA treatment in patients with persistent acromegaly. We retrospectively analyzed data from 108 consecutive patients with acromegaly who were followed up by our clinic after undergoing surgery between 2002 and 2014. Patients who were cured after surgery were excluded. We only selected 43 patients (21 males, 22 females, mean age 52.8 ± 11.9 years) who did not meet the criteria of remission postoperatively, who were treated with SSA for at least six months and had normal thyroid function. Patients were divided into three groups (well-controlled, controlled, and active) according to their IGF-1 and growth hormone (GH) levels. All patients underwent an evaluation of TV and total thyroid nodule volume (TTNV) by ultrasound. TTNV decreased significantly in patients with well-controlled acromegaly (0.44 [0.75] to 0.23 [0.73], p < 0.001). TTNV did not change in controlled patients (0.18 [1.28] to 0.13 [1.54], p = 0.959); however TTNV increased in patients with active acromegaly (0.77 [1.46] to 1.03 [1.88], p = 0.028). Successful medical treatment of patients with active acromegaly decreases thyroid nodule volume. Sustained exposure to IGF-1 may cause an increase in thyroid nodule volume in patients with acromegaly.

A total of 165 patients with papillary thyroid cancer and 172 controls were included in this case-control study. VDR gene single-nucleotide polymorphisms FokI (rs2228570), BsmI (rs1544410), ApaI (rs7975232), and TaqI (rs731236) were evaluated using reverse-transcription polymerase chain reaction. VDR gene polymorphisms BsmI, ApaI, and TaqI did not differ between the papillary thyroid cancer group and control group (p > 0.05, each). BsmI, ApaI, and TaqI were not associated with papillary thyroid cancer risk. The VDR gene FokI CT/TT genotype was associated with an increased papillary thyroid cancer risk (CT vs CC: odds ratio = 1.71, 95% confidence interval = 1.15-2.76, p = 0.028; TT vs CC: odds ratio = 2.44, 95% confidence interval = 1.29-4.62, p = 0.005; CT/TT vs CC: odds ratio = 1.88, 95% confidence interval = 1.20-2.96, p = 0.006; CT/CC vs TT: odds ratio = 1.80, 95% confidence interval = 1.05-3.20, p = 0.041). VDR gene polymorphisms were not in linkage disequilibrium. The FokI TT genotype was associated with having T3 and T4, stage III/IV, extra-thyroidal invasion. The FokI CT/TT or TT genotype was associated with developing N1 status, multifocality, tumor size ≥10 mm, and treatment with radioiodine therapy. Persistence/recurrence did not differ between the FokI genotypes. Carriers of the FokI T allele were at an increased risk of more advanced tumor-node-metastasis stage, greater tumor size, multifocality, and extra-thyroidal invasion of papillary thyroid cancer compared with the CC genotype. VDR gene FokI T allele and TT genotype correlated with aggressiveness of papillary thyroid cancer; thus, FokI could be useful as a poor prognostic factor to assess the high risk of papillary thyroid cancer.

Abstract
INTRODUCTION Vitamin D deficiency is a common health problem. Vitamin D supplements are used to improve vitamin D status; however, there are contradictory data related to what doses to give and how often they should be given. Many studies have investigated the effects of vitamin D supplementation on muscle strength, but the results remain controversial. We aimed to compare the effects and safety of single high-dose with daily low-dose oral colecalciferol on 25(OH)D levels and muscle strength in postmenopausal women with vitamin D deficiency or insufficiency. METHODS AND DESIGN Sixty healthy postmenopausal women who had serum vitamin D levels < 20 ng/mL (50 nmol/L) were enrolled in the study. Group 1 (n = 32) was given daily oral dosages of 800 IU vitamin D3, and group 2 (n = 28) was given a single oral dose of 300,000 IU vitamin D3. Serum vitamin D levels and muscle strengths were measured at the beginning, 4th, and 12th week. Muscle strength tests were performed at 60° using a Biodex system 3 isokinetic dynamometer. RESULTS Pretreatment vitamin D levels did not differ between the two groups (10.2 ± 4.4 ng/mL (25,4 ± 10,9 nmol/L); 9.7 ± 4.4 ng/mL (24,2 ± 10,9 nmol/L), p > 0.05). A significant increase in vitamin D levels was observed in both groups at 4 and 12 weeks after vitamin D3 treatment. The increase in the single-dose group was significantly higher than the daily low-dosage group at the 4th week (35.9 ± 9.6 ng/mL (89,6 ± 23,9 nmol/L), 16.9 ± 5.8 ng/mL (42,1 ± 14,4 nmol/L), p = 0.01). The increase in the single-dose group was significantly higher than in the daily low dosage group at the 12th week (23.4 ± 4.7 ng/mL (58,4 ± 11,7 nmol/L), 19.8 ± 7.2 ng/mL (49,4 ± 17,9 nmol/L), p = 0.049). The quadriceps muscle strength score increased significantly in the daily group at the 4th week (p = 0.038). The hamstring muscle strength score increased significantly in the daily group at the 12th week (p = 0.037). CONCLUSION Although daily administration routes are more effective in improving muscle strength, a single administration is more effective in increasing vitamin D levels. TRIAL REGISTRATION NUMBER ISRCTN14226530 (04.07.2018), Name of the registry: ISRCTN registry, The study was retrospectively registered.

Abstract
Background Cardiovascular disease (CVD) is reported to be higher in elderly diabetics. Serum heart-type fatty acid binding protein (H-FABP) is a serum marker of myocardial ischemia. We aimed to investigate the association between serum H-FABP level and conventional cardiovascular risk factors, inflammatory markers and subclinical atherosclerosis in elderly diabetics without overt CVD. Patients and methods A total of 50 elderly diabetic patients without overt CVD and 30 age-, sex- and body mass index (BMI)-matched healthy controls were enrolled. Anthropometric and biochemical parameters, serum H-FABP, high-sensitivity C-reactive protein (hs-CRP), fibrinogen and carotid intima-media thickness (CIMT) were measured. Logistic regression analyses (adjustments for age, sex, hypertension, smoking, diabetes, BMI, blood pressure, lipid, blood glucose, hemoglobin A1c, hs-CRP and fibrinogen) were performed to evaluate the association between H-FABP and cardiovascular risk factors and atherosclerosis indices. Results Serum fibrinogen (421.50±85.52 mg/dL vs 319.17±30.77 mg/dL, p=0.023), CIMT (0.70±0.12 mm vs 0.59±0.06 mm, p<0.001) and hs-CRP (5.72±4.50 mg/dL vs 1.60±0.72 mg/dL, p<0.001) were significantly higher in diabetic patients than controls. The mean serum H-FABP level did not differ between groups (1571.79±604.60 ng/mL vs 1500.25±463.35 ng/mL, p=0.905). H-FABP was positively correlated with fibrinogen (r2=0.473, p<0.001), hs-CRP (r2=0.323, p=0.003) and CIMT (r2=0.467, p<0.001). After full adjustments, the serum H-FABP level was independently associated with an increase in the fibrinogen level (odds ratio [OR] =4.21, 95% confidence level [CI] =1.49–11.90). Conclusion Serum H-FABP was similar in the elderly diabetic patients without known CVD when compared with the nondiabetic control group. H-FABP does not possess a high diagnostic value as a cardiovascular marker when used alone; however, it may add supplementary information in patients with a high fibrinogen level.

Abstract
OBJECTIVE This study was designed to compare the serum levels of fibroblast growth factor 23 (FGF23) among patients with gestational diabetes mellitus (GDM) and healthy pregnant women, and to evaluate the association between hormonal and metabolic parameters. SUBJECTS AND METHODS A total of 82 pregnant women were consecutively enrolled in the study. Of these, 46 were diagnosed as having GDM; the remaining 36 healthy pregnant women served as controls in a cross-sectional study design. The womens' ages ranged from 22 to 38 years and gestational ages, from 24 to 28 weeks. Serum samples were analyzed for FGF23 levels using an enzyme-linked immunosorbent assay. RESULTS Serum FGF23 levels were increased in patients with GDM compared with controls (median, 65.3 for patients with GDM vs. 36.6 ng/mL for healthy controls; p = 0.019). Mean fasting glucose (105.6 ± 7.4 vs. 70.2 ± 7.2 mg/dL, p < 0.001), HbA1c (5.6 ± 0.5 vs. 4.9 ± 0.5%, p < 0.001), insulin (median, 11.1 vs. 8.7 µIU/mL, p = 0.006) and HOMA-IR (3.0 (1.8) vs 1.4 (0.6), p < 0.001) levels were significantly higher in patients with GDM than in controls. Serum FGF23 level was positively correlated with body mass index (r2 = 0.346, p < 0.05), FPG (r2 = 0.264, p < 0.05), insulin (r2 = 0.388, p < 0.05), HOMA-IR (r2 = 0.384, p < 0.05). CONCLUSION Serum FGF23 levels were higher in women with GDM compared with controls. The present findings suggest that FGF23 could be a useful marker of cardiovascular disease in GDM.

Abstract
BACKGROUND Recent studies have demonstrated that immune factors might have a role in the pathophysiology of insulin resistance and type 2 diabetes mellitus (T2DM). Inappropriate glycemic control in patients with T2DM is an important risk factor for the occurrence of diabetes complications. The prevalence of celiac disease (CD) is high in type 1 diabetes mellitus however, there are scarce data about its prevalence in T2DM. Our aim was to investigate the prevalence of celiac disease among insulin-using type 2 diabetes patients with inappropriate glycemic control. METHODS IgA tissue transglutaminase antibodies (tTGA IgA) test was performed as a screening test. A total of 135 patients with T2DM whose control of glycemia is inappropriate (HbAlc value >7%) in spite of using insulin treatment for at least 3-months (only insulin or insulin with oral antidiabetic drugs) and 115 healthy controls were enrolled in the study. Upper gastrointestinal endoscopy with duodenal biopsy was performed to all patients with raised tTGA IgA or selective lgA deficiency. RESULTS Gender, age, body mass index (BMI) and tTGA IgA, kreatinin, calcium, LDL-cholesterol (LDL-C), total cholesterol, 25-OH vitamin D3 levels were similar between groups. Systolic and diastolic blood pressure, waist circumference, fasting plasma glucose, postprandial plasma glucose, urea, sodium, HbA1c, LDL-C, triglyceride, vitamin B12 levels were significantly higher in DM group (p < 0.0001). BMI, high-sensitive CRP, microalbuminuria, and AST, ALT, potassium, phosphorus levels were significantly higher in the T2DM group (p < 0.05). HDL-cholesterol and parathormone levels were significantly lower in the T2DM group (p < 0.05). Two of the 135 patients with T2DM were diagnosed with CD (1.45%). CONCLUSIONS The prevalence of celiac disease among patients with type 2 diabetes, with poor glycemic control despite insulin therapy, is slightly higher than the actual CD prevalence in general population. Type 2 diabetic patients with inappropriate control of glycemia in spite of insulin treatment might be additionally tested for Celiac disease especially if they have low C-peptide levels.

Abstract
BACKGROUND Vitamin D deficiency is a common health problem worldwide. Many parts of the human eye, including the epithelium of the cornea, lens, ciliary body, and retinal pigment epithelium, as well as the corneal endothelium, ganglion cell layer, and retinal photoreceptors, contain vitamin D receptor (VDR). Dry eye is also a common health problem. An adequate tear film is required for maintaining health and function of the eye. Tear hyperosmolarity is considered to be the cause of ocular surface inflammation, symptoms, and tissue damage. It is well-documented that vitamin D has an anti-inflammatory action. We aimed to investigate the effect of vitamin D replacement on tear osmolarity in patients with vitamin D deficiency. METHODS A total of 44 patients (38 females, six males, mean age:43.5 ± 12.8 years) with vitamin D deficiency currently managed by the Endocrinology and Metabolism Department of Diskapi Training and Research Hospital in Turkey were enrolled in the study. Patients were given 50,000 units of 25(OH)D3 intramuscularly, once weekly, over a period of eight weeks. All of the patients underwent tear function osmolarity (TFO) measurement initially and eight weeks after vitamin D replacement. Demographic, anthropometric, and biochemistry data of patients were recorded. RESULTS The mean TFO was significantly decreased (313.7 ± 17.3 mOsm/L; 302.7 ± 14.2 mOsm/L, p<0.001) at the end of the second month; 25(OH)D3 concentrations increased from 8.3 ± 3.5 ng/mL to 68.8 ± 22.3 ng/mL (p<0.001). The mean levels of hsCRP, FPG, P were 2.5 ± 2.5 mg/L, 5.09 ± 0.48 mmol/L, 1.06 ± 0.16 mmol/L initially, and 3.8 ± 5.9 mg/L, 5.11 ± 0.68 mg/dL, 1.09 ± 0.16 mmol/L after vitamin D replacement, respectively (p>0.05). The mean Ca level was 2.37 ± 0.07 mmol/L initially and 2.35 ± 0.07 mmol/L after vitamin D replacement (p<0.05). The change of TFO was negatively correlated with the variation of 25(OH)D3 before and after replacement in patients with dry eye disease (r=-0.390, p=0.049). CONCLUSIONS As a consequence of the presence of VDR and 1α-hydroxylase in different parts of the eye, vitamin D replacement improves tear hyperosmolarity that is considered to be induced by ocular surface inflammation.

Abstract
OBJECTIVE Pentraxin 3 (PTX3) is an acute-phase glycoprotein, which is increased in patients with cardiovascular disease (CVD) and considered as a predictor of CVD in the general population. Both functional and nonfunctional adrenal tumors are associated with a higher risk of cardiovascular events and mortality. We aimed to investigate plasma PTX3 levels in patients with functioning and nonfunctioning adrenal tumors and determine its relationship with cardiovascular risk factors. METHODS Twenty-one patients with functional adrenal tumors (11 pheochromocytomas, 9 Cushing syndrome, and 1 primary hyperaldosteronism), 28 patients with nonfunctional adrenal incidentalomas, and 40 healthy controls were enrolled in the study. Serum PTX3 levels were measured using a human PTX3 enzyme-linked immunosorbent assay. RESULTS PTX3 concentrations were significantly higher in the adrenal tumor group compared with the control group (3,001.64 ± 374.64 pg/mL vs. 1,173.59 ± 168.89 pg/mL; P<.001). PTX3 concentrations were positively correlated with carotid intima media thickness (CIMT) (r2, 0.464; P<.001), high-sensitivity C-reactive protein (hsCRP) (r2, 0.551; P<.001), diastolic blood pressure (r2, 0.334; P = .003), systolic blood pressure (r2, 0.312; P = .006), and urinary metanephrine concentrations (r2, 0.320; P = .041). Serum PTX3 concentrations in patients with functional adrenal tumors and comorbidities including hypertension, diabetes mellitus, or CVD were higher than in those without comorbidities (3,654.54 ± 447 pg/mL vs. 1,026.96 ± 447.97 pg/mL; P = .008). CONCLUSION We found that serum PTX3 concentrations increased in both functional and nonfunctional adrenal tumors. PTX3 levels were correlated with cardiovascular risk factors such as CIMT, hsCRP, and blood pressure. ABBREVIATIONS BMI = body mass index; CIMT = carotid intima-media thickness; CRP = C-reactive protein; CT = computed tomography; CVD = cardiovascular disease; FGF2 = fibroblast growth factor 2; hsCRP = high-sensitivity C-reactive protein; PA = primary hyperaldosteronism; PTX3 = pentraxin 3.

Abstract
BACKGROUND Dry eye syndrome is one of the complaints of diabetic patients. The aim of the present study was to evaluate the tear functions in pregnant women with gestational diabetes mellitus (GDM) using tests: Schirmer, tear break-up time (TBUT), and tear film osmolarity (TFO) tests and the Ocular Surface Disease Index score (OSDI). METHODS Pregnant women with GDM (Group 1, n=46) and healthy pregnant women (Group 2, n=36) were enrolled. Initially, all participants were asked to answer the OSDI and then they underwent a detailed ophthalmic examination including Schirmer, TBUT, and TFO tests. The individuals with ocular or systemic disorders that might affect the tear function tests and who were using topical medications were excluded. RESULTS The results of Schirmer, TBUT, TFO tests and OSDI scores were 11.20±4.93 mm, 5.59±2.16 sec, 309.65±14.80 mOsm/L, and 9.59 ± 9.69 in Group 1, respectively, and 12.33±5.33 mm, 5.67±2.68 sec, 308.36±16.00 mOsm/L, and 10.62±8.66 in Group 2, respectively. There was no significant difference in any of the tear function tests and OSDI scores between the study groups (p>0.05). CONCLUSION GDM seems to have no negative effects on tear function tests. This may be due to a lack of duration of hyperglycemia long enough to affect the tear function tests of pregnant women.

Abstract
EMC6 (endoplasmic reticulum membrane protein complex subunit 6), also known as transmembrane protein 93, is a novel positive autophagy regulator. In this report, we evaluated the anti-tumor activity of EMC6 in glioblastoma cells in vitro and in vivo. Our data show that overexpression of EMC6 in three glioblastoma cell lines (SHG44, U87 and U251) suppresses tumor cell growth by activating autophagy, but fails to induce cell apoptosis. EMC6-mediated autophagy was associated with inactivation of the PIK3CA/AKT/mTOR signaling pathway. Accordingly, EMC6 knockdown in glioblastoma cells had the opposite effect; it promoted cell growth. Overexpression of EMC6 also sensitized glioblastoma cells to the chemotherapy drug, temozolomide, to further suppress tumor growth. Our data indicate that EMC6-induced autophagy may play a positive role in suppressing the development of glioblastoma.

Abstract
Background: Our previous study indicates that leptin enhances gastric cancer (GC) invasion. However, the exact effect of leptin on GC metastasis and its underlying mechanism remain unclear. Intercellular adhesion molecule-1 (ICAM-1), a major molecule in stabilising cell–cell and cell–extracellular matrix interactions, is overexpressed and has crucial roles in tumour metastasis. Methods: Here, we investigated leptin and ICAM-1 expression in GC tissues. Furthermore, we characterised the influence of leptin on ICAM-1 expression in GC cells and elucidated the underlying mechanism. Results: Leptin and ICAM-1 were overexpressed in GC tissues, and a strong positive correlation was observed. They were also related with clinical stage or lymph node metastasis. Furthermore, leptin induced GC cell (AGS and MKN-45) migration by upregulating ICAM-1, and knockdown of ICAM-1 by small interference RNA (siRNA) blocked this process. Cell surface ICAM-1, as well as soluble ICAM-1 (sICAM-1), was also enhanced by leptin. Moreover, leptin increased ICAM-1 expression through Rho/ROCK pathway, which was attenuated by pharmacological inhibition of Rho (C3 transferase) or its downstream effector kinase Rho-associated protein kinase (ROCK) (Y-27632). Conclusions: Our findings indicate that leptin enhances GC cell migration by increasing ICAM-1 through Rho/ROCK pathway, which might provide new insight into the significance of leptin in GC.

Abstract
SUMMARY IgG4-related disease is characterized by histologic fibrosis with IgG4-positive plasma cell infiltration. Our study evaluated MR imaging features of IgG4-related disease in the head and neck and brain. Images from 15 patients were retrospectively evaluated for the location, signal intensity, and enhancement patterns of lesions. Lacrimal gland enlargement was observed in 8 cases. Other lesions included orbital pseudotumor in 5, pituitary enlargement in 5, and cranial nerve enlargement in 7; the infraorbital nerve was involved in 4. All lesions were hypointense on T2-weighted images, which is typical for IgG4-related lesions. Multiple sites were involved in the head and neck and brain in 11 patients. The diagnosis of IgG4-related disease should be considered in a patient presenting with T2 hypointense lacrimal gland, pituitary, or cranial nerve enlargement, or a T2 hypointense orbital mass, especially if multiple sites in the head and neck are involved in the presence of elevated serum IgG4.

Abstract
BACKGROUND Endotoxin (Et) adsorption therapy with a column of polymyxin B-immobilized fibers (PMX) is effective in improving the partial pressure of arterial oxygen/fraction of inspired oxygen ratio (PaO(2)/FiO(2) ratio) and increasing mean arterial blood pressure (MAP) in sepsis. S100A12 and soluble receptor for advanced glycation end product (sRAGE) are useful as early markers of acute lung injury. PURPOSE To investigate the effect of improving the PaO(2)/FiO(2) ratio by PMX-direct hemoperfusion (PMX-DHP) on production of S100A12 and sRAGE. SUBJECTS AND METHODS Sepsis patients after surgery for perforation of the lower gastrointestinal tract were adopted as the subjects. We retrospectively reviewed the cases of 20 patients on mechanical ventilation and continuous administration of norepinephrine. We recorded PaO(2)/FiO(2) ratio, MAP, and norepinephrine doses. S100A12, sRAGE, and Et levels were measured before and after PMX-DHP. RESULTS The PaO(2)/FiO(2) ratio and MAP improved significantly after PMX-DHP (p < 0.05). S100A12 and Et decreased significantly after PMX-DHP (p < 0.05). No differences were observed in sRAGE. CONCLUSION S100A12 is useful as a marker that reflected improvement in the PaO(2)/FiO(2) ratio after PMX-DHP. We consider PMX-DHP to be useful as adjunctive therapy for sepsis that reduces the Et and corrects the pathology in the early stage.

Abstract
Although endovascular surgery is now widely used to treat intracranial aneurysms, no comparative studies of clipping versus endovascular surgery to address distal ACA aneurysms at the same institution are available. We compared the results of these treatment modalities to address distal ACA aneurysms at our institution. We treated 68 patients with ruptured distal ACA aneurysms (endovascular surgery, n=13; clipping surgery, n=55). We performed a retrospective comparison of the treatment outcomes. To study the efficacy of endovascular surgery we classified all our cases into three types: type A were small-necked aneurysms, type B were wide-necked aneurysms on the parent artery, and type C were aneurysms in which the A3 portion of the ACA arose from the aneurysmal dome near the neck. Intraoperative hemorrhage occurred in 7.7% of aneurysms treated by endovascular surgery and in 34.5% treated by clipping surgery. In 7.7% of the endovascularly-treated aneurysms we noted coil migration during embolization surgery; venous infarction due to cortical vein injury occurred in 7.3% of clipped aneurysms. Of the endovascularly-treated aneurysms, 7.7% manifested post-embolization hemorrhage; 23.1% manifested coil compaction. In clipping surgery, postoperative rerupture occurred in 1.8% of the aneurysms; one patient presented with postoperative acute epidural hematoma. Clip dislocation was noted in 1.8% of aneurysms. Angiography was indicative of post-treatment vasospasm in 7.7% of aneurysms treated endovascularly and in 50.9% of the clipped aneurysms. The clinical outcome showed no significant difference between endovascular surgery and clipping surgery.

Abstract
BACKGROUND Erectile dysfunction (ED) is prevalent in end-stage renal disease (ESRD) and has been associated with impaired health-related quality of life (HRQoL). HRQoL, in turn, is related to morbidity and mortality in ESRD patients. Previous studies have shown improved HRQoL with ED treatment using sildenafil and vardenafil. However, no study has examined the effects of sildenafil or vardenafil on HRQoL in impotent ESRD patients. Furthermore, vardenafil has never been tested and its safety profile has not been determined in ESRD patients. The aim of this randomized crossover study was to compare the effects of sildenafil and vardenafil on measures of HRQoL and on ED scores as well as to determine the safety profile of vardenafil in ESRD patients. METHODS In 32 haemodialysis patients with impotence, ED and HRQoL were evaluated by the International Index of Erectile Function (IIEF-5) and the 36-item Short-Form Health (SF-36) surveys, respectively. Patients were randomized into sildenafil and vardenafil groups. After a 4-week treatment and 2-week washout periods, crossover was performed and an additional 4-week treatment was administered. IIEF-5 and SF-36 surveys were given before and after each treatment period. Adverse effects were evaluated by interview. Friedman tests and Bonferroni-adjusted Wilcoxon signed-rank tests were used to compare groups and for post hoc analysis, respectively. RESULTS IIEF-5 and SF-36 scores were significantly improved by both sildenafil and vardenafil compared to pretreatment values. There were no differences between sildenafil and vardenafil with respect to the studied parameters. Adverse effect profiles were also similar. No patient dropped out because of side effects. CONCLUSIONS Sildenafil and vardenafil caused similar improvements in ED and HRQoL in haemodialysis patients. Vardenafil was well tolerated in our patient population.

Abstract
SUMMARY As endovascular surgery (EVS) of symptomatic unruptured aneurysms can result in symptom exacerbation due to intra-aneurysmal thrombosis or lump formation by coils, this treatment remains controversial. We present five women ranging in age from 58 to 76 years (mean 65.6 years) who suffered post-EVS symptom exacerbation attributable to local inflammation. The aneurysms measured from 8 to 25 mm (mean 19 mm) and were located at the cavernous portion in four patients and at the origin of the ophthalmic artery in one. All underwent endosaccular embolization under local anesthesia. Immediately after embolization, 24 h anticoagulation therapy was started via the continuous injection of heparin; they also received antiplatelet therapy. At one to three days post-EVS, all five patients manifested worsening of their cranial nerve symptoms. In three other patients the symptoms were improved after EVS. We posit that inflammation induced by coil embolization may worsen cranial nerve symptoms transiently. Our findings suggest that post-EVS followup is necessary and that patients exhibiting aninflammatory reaction be treated with anti-inflammatory drugs.

Abstract
SUMMARY Angiosarcoma is a rare, highly malignant tumor with a poor clinical outcome. From January 2004 to September 2005, we advocated transarterial chemotherapy using a port system for four patients with angiosarcomas of the face and scalp. A heparin coated ANTHRON P-Ucatheter was introduced into the feeding artery. The proximal part of the P-U catheter was connected to the port system and buried in subcutaneous tissue. The amount of chemotherapeutic drug applied using the port system was almost the same as the conventional intravenous dose. Paclitaxel was the standard agent, at 50-100 mg/diluted in 15-30 ml of physiological saline fluid slowly injected over 0.5-1 hour. For immunotherapy where appropriate, r-IL2 was mainly used at a dose of 70.000U/ diluted in 5 ml of physiological saline fluid injected into the port system over 30 seconds. This was continued for two to three weeks (five days/week) until recognition of a disappearance of the tumor. Macroscopic size reduction of the tumor was achieved in three out of the four cases. One case could not be evaluated because of eruptions induced by immunotherapy. Unfortunately two patients died after placement of port system, but the other two are still alive and are enjoying useful lives. Transarterial infusion chemotherapy using such a port system may be particularly effective for angiosarcoma in the early stages because small lesions with limited invasion mean a small territory of blood supply to be covered, and useful life was possible because the port system embedded in subcutaneous tissue allows treatment in an out-patient clinic.

Abstract
SUMMARY With the existence of vasospasm, it is recommended that direct clipping surgery for a ruptured aneurysm be delayed until its disappearance, but this may be associated with aneurysmal re-rupture resulting in a poor outcome for the patients. Indications for endovascular coil embolization in such cases are discussed. Since November in 2003, we have applied endovascular coil embolization in 11 consecutive patients with ruptured aneurysms and apparent vasospasm of the parent artery from two to 17 days (average: eight days) after initial subarachnoid hemorrhage. Three patients had aneurysmal re-rupture before treatment, but the other eight had only experienced the one episode of subarachnoid hemorrhage. With one exception, all endovascular procedures could be successfully performed, resulting in complete occlusion of aneurysms and remarkable dilatation of inserted spastic vessels without technical complications or aneurysmal re-rupture. For the one case of failure because of a tortuous artery, direct clipping surgery was performed after disappearance of vasospasm. Cerebral infarction occurred in four, but only one correlated with the distribution of catheterization, and neurological deficits had completely disappeared three months after the onset. This preliminary report concerning a small number of patients suggests that endovascular coil embolization is not contra-indicated for aneurysms with vasospasm requiring catheterization. A large study for confirmation is now warranted.

Abstract
SUMMARY Whether endovascular surgery is able to reduce the mass effects of unruptured aneurysms is still controversial, although some reports have suggested efficacy in cases of internal carotid artery aneurysms with cranial nerve palsy. Here we assessed outcome in a series of cases. Between April 1992 and April 2005, 18 patients with unruptured internal carotid artery aneurysms presenting with cranial nerve palsy were treated by endovascular surgery. The patients were two males and 16 females aged from 19 to 84 (mean 59.6 years). Aneurysms were located in the cavernous portion in 14, at the origin of the ophthalmic artery in one and at the origin of P-com in three. The aneurysms were all embolized using Guglielmi detachable coils, Interlocking detachable coils, Cook's detachable coils or Trufill DSC and detachable Balloons were applied to occlude the proximal parent artery.We analyzed the efficacy of endovascular surgery for such aneurysms retrospectively. The mean aneurysm size was 21.4 mm and the mean follow-up period was 57.7 months. Palsy of II(nd) cranial nerve was evident in three patients, of the III(rd) in eight, of the V(th) and V(th) in one each, and of the VI(th) in nine. Post embolization occlusion was complete in nine patients and neck remnant in the other seven. Regarding complications of endovascular surgery, one case (5.6%) showed TIA after embolization. Overall 11 (46%) cranial nerve symptoms showed complete resolution, eight (33%) showed some improvement, and five (21%) were unchanged. In three cases (12.5%), the symptoms worsened after treatment. The shorter the duration of symptoms was a factor predisposing to resolution of symptoms. In complete resolution cases, the timing of treatment after symptoms appeared and the time of complete resolution were in proportion. These results showed that there is no difference in reduction of mass effects between surgical clipping and endovascular surgery for unruptured internal carotid artery aneurysms.With endovascular surgery, the rapidity of treatment after symptoms is the most important factor for successful results.

Abstract
SUMMARY Transvenous occlusion of an affected sinus has become a standardized curative treatment for dural sinus arteriovenous fistula. A 57-yearold man with a left sigmoid sinus isolated dural AVF was successfully treated with tansarterial followed by transvenous embolization. Followup angiography one year and two months thereafter showed complete disappearance of the dural AVF. However, one year later, superior parasagittal sinus dural arteriovenous fistula had newly developed, for which the etiology and a careful point for follow-up are here discussed.

Abstract
We describe the case of a 26-year-old man who presented with symptoms compatible with Lhermitte sign that occurred during yawning. It was associated with congenital partial aplasia of the posterior arch of the atlas. Cervical multisection-detector CT myelography during yawning showed compression of the upper cervical cord due to the inward mobility of the isolated posterior tubercle. The symptoms completely disappeared following removal of the isolated posterior tubercle.

Abstract
SUMMARY Polyvinyl alcohol (PVA) particles have been widely used as an embolic material for endovascular treatment of vascular enriched tumors, especially for meningiomas. However, there are disadvantages with their use due to the fact that they are radiolucent, with a very irregular shape and a tendency for self-adhesion. With alternative organic liquids there is also a possibility of toxicity. We have therefore developed a new embolic material, platinum balls, which feature radioopacity, a relatively well-defined oval shape, multi-pitted and indented surfaces on electron microscopy and a lower tendency for self-adhesion Based on positive findings in experimental studies, embolization of meningiomas was conducted with platinum balls in 27 patients and the results compared with findings for a matched group previously treated with PVA particles.Total volume of blood transfused during surgery was comparable in the two cases, although a tendency for lower values was noted with the platinum balls, and outcome was equally positive.

Abstract
SUMMARY The purpose of this paper is to clarify advantages and disadvantages of platinum liquid coils as an embolic material for AVMs. During the last eight years, 50 endovascular procedures using liquid coils were conducted in our institute for 19 cases with AVMs, 15 of which were located in the eloquent area. All but one presented with haemorrhage, the exception demonstrating repeated ischemic symptoms. Only liquid coils were used as the embolic material to obliterate the nidus and feeders. In ten of the 15 patients with AVMs located in the eloquent area and one case rejecting surgery, liquid coil embolization was applied one to 11 times (average 3.5 times) to achieve decrease in size and this was then followed by radiosurgery. The remaining eight AVM patients underwent total removal after liquid coil embolization. No complications were encountered during the peri-embolization period. In all cases, the purpose of embolization was to diminish the size to facilitate radiosurgery and decrease bleeding during surgery. The liquid coil has advantages as a material for embolization of AVMs; it is non-toxic and bioinart material; it seldom occludes normal minute vascular channels; when it used in a nidus, it seldom to migrates in the venous direction, and it has good radio-opacity and offers good marking for surgery. Appropriate applications include preoperative embolization or pre-radiosurgical embolization of AVMs, especially when staged embolizations are performed to reduce risk of perfusion pressure breakthrough in patients which are large or located in the eloquent area.

Abstract
UNLABELLED OBJECTIVE, BACKGROUND: Cerebral angiography, performed within 24 hr of aneurysmal rupture, carries an increased risk of rebleeding. We have investigated the rerupture rate during angiography procedures under deep general anesthesia and the factors that contribute to rebleeding. METHODS We divided 69 patients who had experienced aneurysmal rerupture into 2 groups. Group I (n = 13) suffered rebleeding during cerebral angiography and group II (n = 56) who rebled at a different time. We assessed the effects on rebleeding of the (1) time between the first insult and angiography, (2) WFNS clinical grade on admission, (3) blood pressure during angiography, (4) age and sex, (5) Fisher classification on admission, (6) aneurysmal site, and (7) Glasgow outcome score (GOS). RESULTS Factors that had a statistically relevant effect on rebleeding during cerebral angiography (Group I) were the performance of angiography within 3 hr of the initial insult, the admission grade, and the aneurysmal site. Especially, the rerupture events during cerebral angiography were concentrated within 3 hr of the initial insult; the rate was 23.9% when angiograms were obtained within 3 hr of onset. Group I patients manifested a worse clinical grade and middle cerebral artery (MCA) aneurysms were prevalent in this group. However, there was no significant difference between the 2 groups with respect to blood pressure, age, sex, Fisher classification, and GOS. CONCLUSIONS Cerebral angiography at ultra-early timing (within 3 hr of the insult) carries a high risk of aneurysmal rerupture, even if the procedure is performed under deep anesthesia and normotensive blood pressure. Cerebral angiography during that period should be avoided.
