Abstract
AIM To assess the value of semi-quantitative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and quantitative diffusion-weighted imaging parameters combined with human epididymis protein 4 (HE4) in predicting the pathological grade and lymphovascular space invasion (LVSI) of endometrioid adenocarcinoma (EAC). MATERIALS AND METHODS Between October 2018 and December 2021, 60 women (mean age, 55 [range, 32-77] years) with EAC underwent preoperative pelvic MRI and HE4 level measurements. The positive enhancement integral (PEI), time to peak, maximum slope of increase (MSI), and maximum slope of decrease were measured by manually drawing a region of interest on the neoplastic tissue. The receiver operating characteristic curve was used to calculate the diagnostic efficiency of the single parameter and combined factors. RESULTS Lower apparent diffusion coefficients (ADCs) were observed in high-grade tumours (G3) than in low-grade tumours (G1/G2). PEI, MSI, and HE4 levels were higher in the high-grade tumours than in the low-grade tumours (p<0.05). The area under the curve (AUC) for G3 diagnosis using multiparametric MRI combined with HE4 was 0.929. ADC values were significantly lower in the EAC with LVSI than in those without LVSI. Tumours with LVSI showed higher PEI and HE4 levels than those without LVSI (p<0.05). The AUC for LVSI-positive diagnosis using multiparametric MRI combined with HE4 was 0.814. CONCLUSION Semi-quantitative DCE-MRI, ADC values, and serum HE4 levels can be used to predict tumour grade and LVSI, and the prediction efficiency of multiparametric MRI combined with serum HE4 is better than that of any single factor.

Abstract
This study aims to analyze the clinical characteristics and genetic variations of two cases with developmental delay and lactic acidosis in a family, and to explore the relationship between genetic variations and clinical features. A retrospective analysis was conducted on the clinical characteristics of two siblings with developmental delay and lactic acidosis who were treated at the Neonatal Department of Children's Hospital of Chongqing Medical University in May 2019 and December 2021, respectively. Whole-exome sequencing was used to detect genetic variations in the affected children. Homology modeling of the BCS1L protein was performed to analyze the structural and functional changes of the protein. The correlation between genetic variations and clinical phenotypes was analyzed. The results showed that the main clinical features of the two affected children in this family were manifestations of mitochondrial respiratory chain complex Ⅲ deficiency, including prematurity, developmental delay, respiratory failure, lactic acidosis, cholestasis, liver dysfunction, renal tubular lesions, coagulation dysfunction, anemia, hypoglycemia, hypotonia, and early death. Whole-exome sequencing revealed a novel deletion mutation c.486_488delGGA (p.E163del) and a novel missense mutation c.992C>T (p.T331I) in the BCS1L gene. Structural analysis of the homology modeling showed that the compound heterozygous mutation had a significant impact on protein function. In conclusion, the novel mutation site c.992C>T (p.T331I) in the BCS1L gene is a "likely pathogenic" mutation, and the compound heterozygous mutation is closely related to the phenotype of mitochondrial respiratory chain complex Ⅲ deficiency.

Abstract
Objective: To investigate the safety and effect of laparoscopy for the treatment of biliary stricture after the biliary dilatation operation. Methods: The clinical data of 78 patients,including 27 males and 51 females aged (48.6±14.2)years(range:17 to 76 years),who presented biliary stricture after biliary dilatation operation from January 2017 to June 2021 in the Department of Minimally Invasive Hepatobiliary Surgery,Hunan Provincial People's Hospital,were retrospectively collected,with 38 cases in the laparoscopy group and 40 cases in the laparotomy group. Of the 78 patients,there were 67 cases of cholangiojejunostomy stricture and 11 cases of stricture of the high intrahepatic bile duct. Statistical methods such as t-test and χ2 test were carried out to compare perioperative clinical data and follow-up information between the two groups. Results: Less intraoperative blood loss((102.6±76.4)ml vs. (162.5±105.9) ml, t=-2.874,P=0.005),shorter postoperative stay length of stay((10.5±3.7)days vs. (14.5±6.4)days, t=-3.379,P=0.001) and shorter waiting time for postoperative anal exhaust((2.0±0.6)days vs. (2.5±0.9)days, t=-2.827,P=0.006) were found in the laparoscopy group than that in the laparotomy group,with statistically significant differences. While there was no statistically difference in the operative time((252.8±54.7)minutes vs. (257.4±68.6)minutes,t=-0.331,P=0.742). Postoperative review and follow-up did not show statistically significant differences between the two groups in the residual stone rate(5.3%(2/38) vs. 5.0%(2/40)) and the incidence of recurrent biliary stricture(5.3%(2/38) vs. 7.5%(3/40))(both P>0.05). Conclusion: Laparoscopy may be safe and effective in the treatment of biliary stricture after the biliary dilatation operation,with less trauma,faster recovery compared to laparotomy.

Abstract
Objective: To observe the platinum drugs resistance effect of N-acetyltransferase 10 (NAT10) overexpression in breast cancer cell line and elucidate the underlining mechanisms. Methods: The experiment was divided into wild-type (MCF-7 wild-type cells without any treatment) group, NAT10 overexpression group (H-NAT10 plasmid transfected into MCF-7 cells) and NAT10 knockdown group (SH-NAT10 plasmid transfected into MCF-7 cells). The invasion was detected by Transwell array, the interaction between NAT10 and PARP1 was detected by co-immunoprecipitation. The impact of NAT10 overexpression or knockdown on the acetylation level of PARP1 and its half-life was also determined. Immunostaining and IP array were used to detect the recruitment of DNA damage repair protein by acetylated PARP1. Flow cytometry was used to detect the cell apoptosis. Results: Transwell invasion assay showed that the number of cell invasion was 483.00±46.90 in the NAT10 overexpression group, 469.00±40.50 in the NAT10 knockdown group, and 445.00±35.50 in the MCF-7 wild-type cells, and the differences were not statistically significant (P>0.05). In the presence of 10 μmol/L oxaliplatin, the number of cell invasion was 502.00±45.60 in the NAT10 overexpression group and 105.00±20.50 in the NAT10 knockdown group, both statistically significant (P<0.05) compared with 219.00±31.50 in wild-type cells. In the presence of 10 μmol/L oxaliplatin, NAT10 overexpression enhanced the binding of PARP1 to NAT10 compared with wild-type cells, whereas the use of the NAT10 inhibitor Remodelin inhibited the mutual binding of the two. Overexpression of NAT10 induced PARP1 acetylation followed by increased PARP1 binding to XRCC1, and knockdown of NAT10 expression reduced PARP1 binding to XRCC1. Overexpression of NAT10 enhanced PARP1 binding to LIG3, while knockdown of NAT10 expression decreased PARP1 binding to LIG3. In 10 μmol/L oxaliplatin-treated cells, the γH2AX expression level was 0.38±0.02 in NAT10 overexpressing cells and 1.36±0.15 in NAT10 knockdown cells, both statistically significant (P<0.05) compared with 1.00±0.00 in wild-type cells. In 10 μmol/L oxaliplatin treated cells, the apoptosis rate was (6.54±0.68)% in the NAT10 overexpression group and (12.98±2.54)% in the NAT10 knockdown group, both of which were statistically significant (P<0.05) compared with (9.67±0.37)% in wild-type cells. Conclusion: NAT10 overexpression enhances the binding of NAT10 to PARP1 and promotes the acetylation of PARP1, which in turn prolongs the half-life of PARP1, thus enhancing PARP1 recruitment of DNA damage repair related proteins to the damage sites, promoting DNA damage repair and ultimately the survival of breast cancer cells.

Abstract
Objective: To explore the effect of csn2 gene deficiency on starvation tolerance and extracellular polysaccharides (EPS) synthesis in an oligotrophic environment of Streptococcus mutans (Sm). Methods: The csn2 gene deletion strains and complementary strains of Sm were cultivated and then an oligotrophic growth environment for Sm growth by setting different concentration gradient media were created. Cell growth in oligotrophic environment was detected by growth curve. Biofilm volume was measured by crystalline violet staining. Scanning electron microscopy (SEM) and laser confocal microscope were performed to observe the biofilm structure of Sm. The synthesis of EPS was measured by the anthrone-sulfuric acid method. The expression of genes related to EPS synthesis was evaluated by quantitative real-time PCR (qRT-PCR). Results: The growth curve results showed that the deletion of csn2 gene inhibited the growth of Sm under starvation stress. Furthermore, the results of laser confocal microscope showed that the biofilm EPS/bacteria ratios produced by the wild-type strain, csn2 gene-deficient strain and complement strains under nutrient sufficient culture conditions were 0.44±0.07, 1.05±0.13 and 0.57±0.08 respectively, while the ratios of EPS/bacteria in an oligotrophic environment were 0.93±0.24, 3.05±0.21 and 1.32±0.46 respectively, indicating that the deletion of csn2 gene enhanced the ability of extracellular polysaccharide synthesis of Sm in the oligotrophic environment. The expression levels of EPS synthesis-related genes gtfB and gtfC were up-regulated by 2.5 fold and 1.8 fold respectively and the expression level of gtfD was down-regulated by two-thirds. Conclusions: The csn2 gene deficiency showed multiple effects on the physiological functions and virulence characteristics of Sm, including starvation tolerance and EPS synthesis. These changes might be related to the shift of the complex regulative network caused by csn2 gene deletion.

Abstract
Litter size is one of the most important reproductive traits of sheep, which has pronounced effects on the profit of husbandry enterprises and enthusiasm of breeders. Despite the importance of litter size, the underlying genetic mechanisms have not been entirely elucidated. Therefore, based on a high-density SNP chip, genome-wide comparative analysis was performed between two groups with different fecundity to reveal candidate genes linked to litter size via detection of homozygosity and selection signatures in Luzhong mutton sheep. Consequently, nine promising genes were identified from six runs of homozygosity islands, and functionally linked to reproduction (ACTL7A, ACTL7B, and ELP1), embryonic development (KLF5 and PIBF1), and cell cycle (DACH1, BORA, DIS3, and MZT1). A total of 128 genes were observed under selection, of which HECW1 and HTR1E were related to total lambs born, GABRG3, LRP1B, and MACROD2 to teat number, and AGBL1 to reproductive seasonality. Additionally, the presence of inbreeding depression implies the urgency of reasonable mating system to increase litter size in the present herd. These findings provide a comprehensive insight to the genetic makeup of litter size, and also contribute to implementation of marker-assisted selection in sheep.

A total of 615 questionnaires were distributed and collected, and 615 were valid, with an effective recovery rate of 100%. Results: The detection rates of psychological stress and anxiety of medical staff were 13.82% (85/615) and 25.37% (156/615) , respectively. 31-40 years old and working in key departments were risk factors for psychological stress of medical staff (OR=1.779, 2.127) ; Women, frequently washing hands with soap/hand sanitizer/disinfectant were protective factors for psychological stress (OR=0.520, 0.528) . Medical staff working in designated hospitals and key departments were more likely to have anxiety (OR=2.042, 2.702) ; The high fit of the mask to the face and bridge of the nose was a protective factor for the psychological anxiety of medical staff (OR=0.500) . Conclusion: Medical staff show higher stress and anxiety during the epidemic of COVID-19. Psychological intervention should be carried out early, focusing on men, age 31 to 40, medical staff working in designated hospitals and key departments.

Abstract
Intensive artificial selection has been imposed in Yunshang black goats, the first black specialist mutton goat breed in China, with a breeding object of improving reproductive performance, which has contributed to reshaping of the genome including the characterization of SNP, ROH and haplotype. However, variation in reproductive ability exists in the present population. A WGS was implemented in two subpopulations (polytocous group, PG, and monotocous group, MG) with evident differences of litter size. Following the mapping to reference genome, and SNP calling and pruning, three approaches - GWAS, ROH analysis and detection of signatures of selection - were employed to unveil candidate genes responsible for litter size. Consequently, 12 candidate genes containing OSBPL8 with the minimum P-value were uncovered by GWAS. Differences were observed in the pattern of ROH between two subpopulations that shared similar low inbreeding coefficients. Two ROH hotspots and 12 corresponding genes emerged from ROH pool association analysis. Based on the nSL statistic, 15 and 61 promising genes were disclosed under selection for MG and PG respectively. Of them, some promising genes participate in ovarian function (PPP2R5C, CDC25A, ESR1, RPS26 and SERPINBs), seasonal reproduction (DIO3, BTG1 and CRYM) and metabolism (OSBPL8, SLC39A5 and SERPINBs). Our study pinpointed some novel promising genes influencing litter size, provided a comprehensive insight into genetic makeup of litter size and might facilitate selective breeding in goats.

Abstract
AIM To investigate the changes of water content in brain tissue, the expression of AQP4mRNA after cerebral hemorrhage in rats, and the intervention effect of Protease activated receptor 1 inhibitor (PAR1 inhibitor) on both. METHODS Establish sham operation group (Sham group), ICH group, ICH+PAR1 inhibitor high-dose group (PI(H)group), ICH+PAR1 inhibitor low-dose group (PI(L)group), 25 in each group. Neural dysfunction scores were performed at 1d, 3d, 7d, 14d, and 21d after surgery, and brain water content and AQP4mRNA content were measured. RESULTS Results: The neurological dysfunction and cerebral edema of rats with cerebral hemorrhage reached the peak at 3 days after operation. With the increase of time, the water content and AQP4mRNA content in the PL(H)group were higher than those in the PI(L)group. The differences were statistically significant. CONCLUSIONS Appropriate inhibition of PAR1 can alleviate cerebral edema around the hematoma and play a role in improving the function of nerve defects. The mechanism may be realized by down-regulating the expression of AQP4mRNA in brain tissue (Tab. 3, Fig. 3, Ref. 25).

Abstract
Sheep, an important source of meat, dairy products and wool, play an essential part in the global agricultural economy. Body weight and body conformation are key traits in the sheep industry; however, their underlying genetic mechanisms are poorly understood. In this study, a GWAS was implemented to identify promising genes possibly linked to birth weight (BW) and body conformation traits in neonatal sheep, using a high-throughput chip (630 K). After quality control, 277 individuals and 518 203 variants were analyzed using gemma software in a mixed linear model. A total of 48 genome-wide suggestive SNPs were obtained, of which four were associated with BW, four with withers height (WH), 11 with body length (BL) and 29 with chest girth (CG). In total, 39 genes associated with BW and body conformation traits were identified by aligning to the sheep genome (Ovis aries_v4.0), and most of them were involved in the cell cycle and body development. Promising candidate genes found included the following: FOS like 2 or AP-1 transcription factor subunit (FOSL2) for BW; potassium voltage-gated channel subfamily D member 2 (KCND2) for WH; transmembrane protein 117 (TMEM117), transforming growth factor beta induced (TGFBI), and leukocyte cell-derived chemotaxin 2 (LECT2) for BL; and trafficking kinesin protein 1 (TRAK1) and LOC101102529 for CG. These results provide cues for similar studies aiming at uncovering the genetic mechanisms underlying body development, and marker-assisted selection programs focusing on BW and body conformation traits in sheep.

Abstract
Objective: To investigate the value of rapid on-site evaluation (ROSE) of bronchoscopy in the diagnosis of pulmonary complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: A retrospective analysis was conducted on the diagnosis and treatment process before and after ROSE examination of 12 patients with pulmonary complications after allo-HSCT who were admitted to the Department of hematology, Tianjin First Central Hospital from January 2017 to June 2019. The diagnostic accuracy of the ROSE was evaluated by comparing the initial diagnosis of ROSE with the final clinical diagnosis. At the same time, the safety of ROSE examination was evaluated and two typical cases were shared. Results: In the 12 transbronchial lung biopsies, there were 5 cases of organizing pneumonia, 3 cases of bronchiolitis obliterans with organizing pneumonia, 1 case of pulmonary fibrosis, 1 case of acute fibrinous and organizing pneumonia, 1 case of pseudomembranous tracheobronchial aspergillosis and 1 case of uncertain diagnosis evaluated by ROSE. Compared with the final clinical diagnosis, there were 10 cases of accurate diagnosis made by ROSE (10/12). All patients were well tolerant to the operation of bronchoscopy. There was only a small amount of bleeding observed during the operation, without pneumothorax and hemoptysis. And no complications related to ROSE occurred. According to the initial diagnosis of ROSE, 10 cases of non-infectious pulmonary complications were treated with methylprednisolone or other immunosuppressive agents and 1 case of Aspergillus infection was given antifungal therapy. Seven patients with non-infectious pulmonary complications improved after treatment. One patient obtained uncertain diagnosis by ROSE was later diagnosed with virus infection by next generation sequencing technology and improved after treatment with foscarnet sodium and immunoglobulin. As of June 30, 2019, 7 patients improved and 5 died. Conclusion: ROSE has the advantages of diagnostic accuracy and rapidity, and is very suitable for patients with critical illness after hematopoietic stem cell transplantation, who are in urgent need of definite diagnosis and prompt treatment, which is beneficial to improve the prognosis of patients.

Abstract
Background Ischemic Stroke (IS) is a major disease which greatly threatens human health. Recent studies showed sex-specific outcomes and mechanisms of cerebral ischemic stroke. This study aimed to identify the key changes of gene expression between male and female IS in humans. Methods Gene expression dataset GSE22255, including peripheral blood samples, was downloaded from the Gene Expression Omnibus (GEO) dataset. Differentially Expressed Genes (DEGs) with a LogFC>1, and a P-value <0.05 were screened by BioConductor R package and grouped in female, male and overlap DEGs for further bioinformatic analysis. Gene Ontology (GO) functional annotation, Protein-Protein Interaction (PPI) network, “Molecular Complex Detection” (MCODE) modules, CytoNCA (cytoscape network centrality analysis) essential genes and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway interrelation analysis were performed. Results In a total of 54,665 genes, 185 (73 ups and 112 downs) DEGs in the female dataset, 461 DEGs (297 ups and 164 downs) in the male dataset, within which 118 DEGs overlapped (7 similar changes in female and male, 111 opposite changes in female and male) were obtained from the GSE22255 dataset. Female, male and overlapping DEGs enriched for similar cellular components and molecular function. Male DEGs enriched for divergent biological processes from female and overlapping DEGs. Sex-specific and overlapping DEGs were put into the PPI network. Overlapping genes such as IL6, presented opposite changes and were mainly involved in cytokine-cytokine receptor interactions, the TNF-signalling pathway, etc. Conclusion The analysis of sex-specific DEGs from GEO human blood samples showed that not only specific but also opposite DEG alterations in the female and male stroke genome wide dataset. The results provided an overview of sex-specific mechanisms, which might provide insight into stroke and its biomarkers and lead to sex-specific prognosis and treatment strategies in future clinical practice.

Abstract
OBJECTIVE Among clinical and morphological criteria, hemodynamics is the main predictor of aneurysm growth and rupture. This study aimed to identify which hemodynamic parameter in the parent artery could independently predict the rupture of anterior communicating artery (ACoA) aneurysms by using multivariate logistic regression and two-piecewise linear regression models. An additional objective was to look for a more simplified and convenient alternative to the widely used computational fluid dynamics (CFD) techniques to detect wall shear stress (WSS) as a screening tool for predicting the risk of aneurysm rupture during the follow-up of patients who did not undergo embolization or surgery. METHODS One hundred sixty-two patients harboring ACoA aneurysms (130 ruptured and 32 unruptured) confirmed by 3D digital subtraction angiography at three centers were selected for this study. Morphological and hemodynamic parameters were evaluated for significance with respect to aneurysm rupture. Local hemodynamic parameters were obtained by MR angiography and transcranial color-coded duplex sonography to calculate WSS magnitude. Multivariate logistic regression and a two-piecewise linear regression analysis were performed to identify which hemodynamic parameter independently characterizes the rupture status of ACoA aneurysms. RESULTS Univariate analysis showed that WSS (p < 0.001), circumferential wall tension (p = 0.005), age (p < 0.001), the angle between the A1 and A2 segments of the anterior cerebral artery (p < 0.001), size ratio (p = 0.023), aneurysm angle (p < 0.001), irregular shape (p = 0.005), and hypertension (grade II) (p = 0.006) were significant parameters. Multivariate analyses showed significant association between WSS in the parent artery and ACoA aneurysm rupture (p = 0.0001). WSS magnitude, evaluated by a two-piecewise linear regression model, was significantly correlated with the rupture of the ACoA aneurysm when the magnitude was higher than 12.3 dyne/cm2 (HR 7.2, 95% CI 1.5-33.6, p = 0.013). CONCLUSIONS WSS in the parent artery may be one of the reliable hemodynamic parameters characterizing the rupture status of ACoA aneurysms when the WSS magnitude is higher than 12.3 dyne/cm2. Analysis showed that with each additional unit of WSS (even with a 1-unit increase of WSS), there was a 6.2-fold increase in the risk of rupture for ACoA aneurysms.

Abstract
Objective: The aim was to investigate the genotype distribution of two major epitopes of large surface protein (PreS1) of hepatitis B in Chinese patients and to explore the association between the genotypes of these two epitopes, and to determine whether PreS1 full-length genotype could be revealed according to the polypeptide sequence of key epitopes. Methods: HBV DNA was extracted from the serum of patients for PCR amplification. 278 samples amplified successfully were sequenced and compared with the known HBV sequences in Genbank to determine the two key epitopes of HBV PreS1 genotype (amino acid epitope 21-47 and 94-117, abbreviated as P21 and P94) and PreS1 full-length genotypes. The correlation among three genotyping approaches was analyzed by Cohen's kappa coefficient to verify the consistency between the key-epitope genotyping and the full-length preS1 genotyping. Results: 232 samples were successfully sequenced. The genotyping based on the kind of P21 epitope protein sequence, 201 cases for genotype C, 23 cases for genotype B and 8 cases for uncertain genotypes and genotyping based on the form of P94 epitope protein sequence, 199 cases for genotype C, 25 cases for genotype B and 8 cases for indeterminate genotypes. Lastly, the genotyping based on sequence of the full-length PreS1 sequence, 207 and 25 cases for genotype C and B. P21 or P94 epitope genotyping and PreS1 full length genotyping were highly consistent, respectively, 96.55% and 96.12%, and the two epitopes (P21and P94) genotyping have parallel consistency (93.10%). Conclusion: In this study, an innovatively genotyping method based on the amino acid sequence of key epitopes was proposed. The genotypes of HBV in china were mainly B and C genotypes, and the genotypes of key conserved epitopes of HBV PreS1 were highly consistent with the full-length genotyping ( > 96%). Moreover, genotyping with one or two key epitopes can be used in place of the full-length genotyping.

Abstract
OBJECTIVE To determine whether the presence of cerebral microbleeds (CMBs) is independently associated with intracranial aneurysm rupture and to identify the time interval of CMB-related intracranial aneurysm rupture. METHODS This cross-sectional study included 1847 patients with unruptured and ruptured intracranial aneurysms from January 2010 to November 2017. Clinical records and imaging, including T2-weighted gradient-recalled echo sequence magnetic resonance imaging that identified the presence of CMBs preoperatively, were evaluated. Univariate analysis and multivariate logistic regression were done to determine which parameters were independent factors for aneurysm rupture. The time interval of CMB-related intracranial aneurysm rupture was also evaluated. RESULTS CMBs confirmed by magnetic resonance imaging were present in 142 patients (142/1847; 7.7%). Of 142 patients with CMBs, 56 patients (including 17 ruptured aneurysms) who received endovascular treatment and another 86 consecutive patients who did not receive embolization or surgery for various reasons were followed for 3-49 months. The incidence of CMB-related intracranial aneurysm rupture was 27.9% (24/86) during the follow-up period. The time interval of CMB-related intracranial aneurysm rupture was 3-27 months (median 9.5 months). Multivariate analyses showed CMBs were significantly correlated with intracranial aneurysm rupture (odds ratio = 1.6; 95% confidence interval, 1.1-2.4; P = 0.010). CONCLUSIONS CMBs were independently associated with intracranial aneurysm rupture. Patients with CMBs have a 60% increased risk of aneurysm rupture compared with patients without CMBs.

Abstract
Introduction Airway obstruction and possible concomitant pulmonary diseases in COPD cannot be identified conventionally with any single diagnostic tool. We aimed to diagnose and grade COPD severity and identify pulmonary comorbidities associated with COPD with ventilation/perfusion single-photon emission computed tomography (V/P SPECT) using Technegas as the functional ventilation imaging agent. Methods 94 COPD patients (aged 43–86 years, Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages I–IV) were examined with V/P SPECT and spirometry. Ventilation and perfusion defects were analyzed blindly according to the European guidelines. Penetration grade of Technegas in V SPECT measured the degree of obstructive small airways disease. Total preserved lung function and penetration grade of Technegas in V SPECT were assessed by V/P SPECT and compared to GOLD stages and spirometry. Results Signs of small airway obstruction in the ventilation SPECT images were found in 92 patients. Emphysema was identified in 81 patients. Two patients had no signs of COPD, but both of them had a pulmonary embolism, and in one of them we also suspected a lung tumor. The penetration grade of Technegas in V SPECT and total preserved lung function correlated significantly to GOLD stages (r=0.63 and −0.60, respectively, P<0.0001). V/P SPECT identified pulmonary embolism in 30 patients (32%). A pattern typical for heart failure was present in 26 patients (28%). Parenchymal changes typical for pneumonia or lung tumor were present in several cases. Conclusion V/P SPECT, using Technegas as the functional ventilation imaging agent, is a new tool to diagnose COPD and to grade its severity. Additionally, it revealed heterogeneity of COPD caused by pulmonary comorbidities. The characteristics of these comorbidities suggest their significant impact in clarifying symptoms, and also their influence on the prognosis.

Abstract
With longer than 100-year experience of development, methods used on birth cohort study have been viewed as having important roles in exploring the probable effects of health and environment exposure both prior to and during the pregnancy in the life circle as infants, children, adolescents, adults, and the elderly. However in China, birth cohort studies started late but with rapid development. Recently, some well-known methods on birth cohort studies were established in mainland China, Hong Kong and Taiwan area. This paper presented an overall review on the progress about birth cohort studies and their prospects, in China.

Abstract
Transvenous embolization is the treatment of choice for cavernous sinus dural arteriovenous fistulas (csDAVFs) despite occasional difficulty in transvenous catheterization. We reported our experience in the treatment of csDAVFs by transarterial Onyx embolization in patients who had failed transvenous catheterization. We reviewed the clinical and radiographic records of csDAVFs patients receiving transarterial Onyx embolization after failed transvenous Onyx embolization at our institution over a period of 31 months. Success was defined as complete or near complete occlusion upon angiographic examination. In seven cases, the microcatheter failed to reach the cavernous sinus; in the remaining case, the internal jugular vein was occlusive. Eight sessions of the embolization and catheterization procedures via the arterial routes were conducted. Among them, five cases via the middle meningeal artery and the other three via the accessory meningeal artery. Angiography, immediately after embolization, revealed complete occlusion in seven cases (87.5 %) and partial occlusion in the remaining case. Angiographic follow-up (range, 6-10 months) showed that all patients achieved complete embolization. In cases where transvenous embolization of the cavernous sinus is difficult, transarterial embolization of the fistulas offers a safe and effective alternative.

Abstract
Objective: To study the expression of membrane HLA-G (mHLA-G) and the receptor immunoglobulin-like transcript 2(ILT2) on lymphocyte and find their association with rejection and cytomegalovirus (CMV) infection after renal transplantation. Methods: A total of 88 cases of renal transplant recipients for the first time from February 2014 to February 2016 were studied in this work. Recipients can be divided into rejection group (n=12) and stable renal function group (n=41) according to whether rejection occurred. Recipients only infected CMV not developed rejection were included in the CMV positive group (n=24). CMV negative group (n=11) including CMV negative recipients once infected CMV.The expression of mHLA-G and ILT2 on lymphocytes were detected by flow cytometry, and the differences among different groups were analyzed. Results: The data showed that after renal transplantation, T and B lymphocytes mHLA-G expression rate was the lowest in the rejection group (0.42%±0.35%, 0.88%±0.47%), having significant difference with renal function stable group and CMV positive group (all P<0.01). In CMV positive group the expression of mHLA-G on T and B lymphocytes was the highest (1.31%±0.69%, 2.01%±0.91%), having significant difference with rejection group (P<0.001). The expression of mHLA-G on B cell was statistically significantly different between CMV positive group and CMV negative group (P<0.05). There was no significant difference in ILT2 expression on B cell among the four groups (P>0.05). The expression rate of ILT2 on T cells was higher in the CMV positive group (36.91%±14.91%), having significant difference with the other three groups (P<0.01). Conclusions: Low expression of mHLA-G on T and B lymphocytes may predict rejection after renal transplantation. High expression of mHLA-G and ILT2 on lymphocytes is prone to CMV infection after renal transplantation .

Abstract
BACKGROUND Symptomatic headaches attributed to unruptured brain arteriovenous malformations (ubAVMs) are very common and affect patients' quality life, but multidisciplinary care of ubAVMs to improve symptomatic headache remains unclear. OBJECTIVE The objective is to identify the features of symptomatic headaches, and to obtain headache outcomes following multidisciplinary care of ubAVMs, as well as provide background on the natural history of ubAVMs. STUDY DESIGN The features of symptomatic headaches and headache outcomes were analyzed in a large cohort of cases after multidisciplinary care of ubAVMs. We have also provided information on the natural history of ubAVMs. SETTING This study was conducted at the Department of Neurosurgery of Zhujiang Hospital where 336 patients from 1998 to 2014 were reviewed by a multidiscipline team. Only 124 patients were eligible. METHODS The demographics, clinical features, imaging features, and headache details of eligible patients were reviewed. An 11-point pain scale score was used to assess symptomatic headaches before, during, and after treatment. The headache outcomes, death or stroke, and adverse functional outcomes (modified Rankin Scale score = 2, mRS = 2) were assessed following multidisciplinary care of ubAVMs. RESULTS Twenty-three (56.1%) of 41 patients had migraine-like headaches located in occipital lobe (P < 0.001), while forty (63.5%) of 63 patients had tension-type-like headaches located in frontotemporal lobe (P < 0.001). For patients with tension-type-like or all types of headache, headache improvement differed between the multidisciplinary group and medical group (87.8% vs. 31.8%, P < 0.001; 85.7% vs. 40.7%, P < 0.001). The risk of death or stroke did not differ between multidisciplinary group and medical group (P = 0.393), whereas the risk of adverse functional outcome (mRS = 2) differed significantly by long-time follow-up (23.0% vs.10.0%, P = 0.022). LIMITATIONS This study provides the initial experience to support multidisciplinary care for ubAVMs to improve symptomatic headaches and patients' quality life, but based on the retrospective study with inherent limitations, larger samples and multi-center trials are needed on this interesting issue. CONCLUSIONS Occipital ubAVM is more likely to present with migraine-like headache, while frontotemporal ubAVM tends to present with tension-type-like headache. The effectiveness of multidisciplinary care for ubAVM to improve headache has been shown, but the natural history of ubAVM patients with headache remains unclear.Key Words: Unruptured brain arteriovenous malformations, headache, headache improvement, natural history.

Abstract
Objective: To investigate the value of MRI in the prenatal diagnosis of abnormal fetal kidneys. Methods: From December 2014 to March 2016, 51 women underwent MRI and were confirmed as having fetuses with abnormal fetal kidneys when follow up. Their clinical and MRI profiles were analyzed retrospectively, including MRI manifestation, the fetal kidney signal intensity of diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC). The signal intensity of DWI and ADC of the abnormal kidney and the normal opposite kidney, and those of the normal and abnormal kidneys in different individuals were compared. The accuracies of MRI and ultrasound in evaluating abnormal fetal kidneys were also compared. Results: MRI could accurately demonstrate the morphological features of abnormal fetal kidneys. There was no statistically significant difference between DWI signal intensity and ADC value of the abnormal kidney[368 ± 125, (1.516 ± 0.420) × 10-3 mm2/s] and the normal opposite one[410 ± 125, (1.362 ± 0.251) × 10-3 mm2/s], P values were 0.165 and 0.184, respectively. The DWI signal intensity of normal kidneys (401 ± 124) was higher than that of renal cysts (182 ± 40, P <0.01), and the ADC value of normal kidneys[(1.306 ± 0.252) × 10-3 mm2/s] was lower than that of renal cysts[(2.912 ± 0.235) × 10-3 mm2/s] and multicystic dysplastic kidneys[(1.870±0.654) ×10-3 mm2/s], P values were <0.01 and 0.045, respectively. The diagnostic accuracy of MRI and prenatal ultrasound for abnormal fetal kidneys were 94% (63/67) and 85% (57/67), respectively. However, there was no statistical difference between the two methods (P=0.070). Conclusion: MRI have an important role in the prenatal diagnosis and evaluation of abnormal fetal kidneys.

Abstract
Since laser was introduced in the field of medicine in 1970's, its application range has continuously expanded. The application of laser in endodontics also increased due to its safety and effectiveness in dental treatments. The majority of the laser application researches in dentistry focused on dentin hypersensitivity, removal of carious tissues, tooth preparations, pulp capping or pulpotomy, and root canal treatment. In this article, we reviewed literature on the effects of laser in the treatments of dental and pulp diseases.

Abstract
OBJECTIVE To study the expression and its diagnostic significance of neutrophil surface adhesion molecules including CD11b, CD15 and CD62L after renal transplantation in recipients with cytomegalovirus (CMV) infection. METHODS Blood samples were collected from 142 kidney transplant recipients, including 95 males and 47 females, who received allogeneic renal transplantation between September 2009 and January 2015 in 309th Hospital of the PLA. Healthy volunteers (22 males and 9 females) were recruited from physical examination center in 309th Hospital of the PLA from September 2009 to January 2015 as healthy control group. Renal transplant recipients were divided into high active CMV infection group, active CMV infection group and CMV negative control group according to CMV-pp65 antigen detection. Neutrophil surface adhesion molecules CD11b, CD15 and CD62L were detected by flow cytometry and their mean fluorescence intensity compared among the groups. Receiver operating characteristic (ROC) curves of CD11b, CD15 and CD62L in detecting active infection in renal transplant recipients were made. RESULTS The mean fluorescence intensity of CD15 in high active CMV infection group(n=17) and active CMV infection group(n=65)were 776.31±89.53 and 554.39±67.89, respectively, with significant differences compared with CMV negative control group (n=60, 334.92±44.69) and healthy control group (n=31, 310.56±39.67) (all P<0.05); the expression proportions of CD11b and CD62L in high active CMV infection group and were 42.31%±6.11% and 40.35%±6.47%, respectively, with significant differences compared with active CMV infection group(62.45%±5.67% and 65.65%±5.33%), CMV negative control group(70.74%±6.55% and 70.37%±6.71%) and healthy control group(72.52%±6.48% and 72.43%±6.51%) (all P<0.05). The optimal cut-off values of CD11b and CD62L in diagnosing active CMV infection group were 56.61% and 44.35%, respectively, with the sensitivity being both 100.00%, the specificity being 76.67% and 58.06% respectively, and the area under the curve (AUC) being 0.851 and 0.628 respectively; the optimal cut-off values of CD11b and CD62L in diagnosing high active CMV infection group were 66.57% and 69.56% respectively, with the sensitivity being 81.54% and 87.69% respectively, the specificity being 100.00% and 98.33% respectively, and the AUC being 1.000 and 0.991 respectively; the optimal cut-off values of mean fluorescence intensity of CD15 in diagnosing high active CMV infection group and active CMV infection group were 542.71 and 408.03 respectively, the sensitivity in the two groups being 100.00% and 98.46% respectively, the specificity being both 100.00%, and the AUC being 1.000 and 0.999 respectively. CONCLUSIONS Neutrophils CD15 expression may be up-regulated in renal transplantation recipients with CMV infection, while neutrophils CD11b and CD62L expressions are down-regulated. Such changes in CD15, CD11b and CD62L expression can be used as a basis for laboratory diagnosis of active CMV infection.

Abstract
OBJECTIVE To explorer the effect of improvement of diabetes on survival after radical pancreatic resection in patients with pancreatic cancer and diabetes. METHODS Seventy-three patients who underwent radical resection for pancreatic cancer at Ruijin Hospital (Shanghai, China) between July 2007 and December 2011 and had preoperative diabetes were retrospectively analyzed. Clinical characteristics and overall postoperative survival were compared between patients with controlled/uncontrolled diabetes. Among patients with uncontrolled diabetes, comparison was made in clinical characteristics and overall postoperative survival between patients with long-term (≥2 years) diabetes and those with new-onset (<2 years) diabetes. RESULTS Controlled diabetes after radical pancreatic resection was observed in 38.4% (28/73) in the patients with pancreatic cancer and diabetes. The median follow-up time was 44.5 months (95CI: 31.7-57.2 months). Patients in whom diabetes was controlled had well-differentiated tumors and longer overall survival compared to patients with uncontrolled diabetes [median overall survival (95%CI) 41.0 (34.2-47.7) months vs 17.0 (14.8-19.2) months, P<0.001]. Among the 45 patients with uncontrolled diabetes, there was no differences in clinic characteristic and overall survival between new-onset (n=21) and long-term diabetes (n=24) [median overall survival (95%CI): 17.8 (15.7-20.1) months vs 15.8 (10.5-21.1) months, P=0.198]. CONCLUSION Good postoperative control of diabetes after radical pancreatic resection in patients with pancreatic cancer and diabetes may predict favorable survival.

Abstract
OBJECTIVE To establish macrophage iron overload model in vitro by co-culture macrophages with iron, and to explore the effect of iron overload on cell reactive oxygen species (ROS) and the impact of ROS on macrophages. METHOD Iron overload group were treated with different concentrations (0, 5, 10, 20, 40, 80 μmol/L respectively) of ferric ammonium citrate (FAC). The control group was the group of macrophages without FAC treatment. We detected the number and state of cells, metabolic activity, the change of phagocytosis, the levels of ROS and reactive nitrogen, and changes of related oxidative stress signaling pathways in different groups. Changes in the above indexes were detected after application of deferasirox (DFX) to remove iron and the antioxidant N -acetylcysteine (NAC) to clear excess oxidative stress. RESULTS (1)The levels of labile iron pool (LIP) in macrophages co-cultivated with iron was increased with the increase of iron concentration in a dose-dependent manner. The LIP levels was the highest in the macrophages treated with 80 μmol/L. (2)The increase of FAC concentration, the metabolic activity of macrophages in the 5 FAC-treated groups decreased to 51.58%, 40.98%, 16.23%, 3.46%, and 0.05% of the activity level of the control group (all P< 0.05). The group with the metabolic activity decreased to 16.23% (20 μmol/L) was selected as the iron overload group for the following experiments. (3)Compared with the control group, the number of macrophages in the iron overload group reduced to 32.80% (P<0.05), and the state of cells changed from adherence to partial suspension. The phagocytosis of macrophages in the iron overload group reduced to 20.40% of the control group (P<0.05). (4)Our further experiment showed that the levels of ROS and the activity nitrogen in the iron overload group increased by 7.71-and 1.45-fold compared with the control group (both P<0.05). The RT-PCR showed up-regulated mRNA expression of genes related with ROS production, i. e. nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX 4) gene related with ROS production and inducible nitric oxide synthase (iNOS) gene related with reactive nitrogen production, down-regulated mRNA expression of glutathione peroxidase 1 (GPX1) gene which participated in ROS clearance. Moreover, mRNA expression of phosphatidylinositol-3-kinase (PI3K) gene involved in oxidative stress signaling pathway in the iron overload group was up-regulated, while fork head protein O3 (FOXO3) which regulated oxidative stress through negative feedback showed a down-regulation level of mRNA expression compared with the control group. (5)After iron chelation and antioxidant treatment, the above-mentioned damage in the iron overload group were partially reversed. CONCLUSIONS The damages of iron overload on macrophages may be mediated by inducing oxidative stress and activating oxidative stress signaling pathways. Our established model provides a method to explore the mechanism of iron overload on macrophage, and may shed some new light on possible therapeutic target in treating iron overload patients.

Abstract
PURPOSE Preoperative embolization of meningiomas decreases intraoperative bleeding and shortens operation time. However, in meningiomas predominantly vascularized by the internal carotid artery (ICA) or vertebral artery (VA) branches, embolization of external carotid artery feeder branches may lead to a hemodynamic increase in blood supply from the ICA or VA, whereas embolization of ICA or VA feeder branches with particle embolic agents may be associated with complications. This study investigated the safety and efficacy of Glubran, a liquid embolic agent, for the embolization of this type of meningioma compared with polyvinyl-alcohol (PVA) particles. MATERIALS AND METHODS From January 2006 to June 2015, 157 consecutive patients (98 females; mean age = 48.3 years) who suffered from meningiomas and were preoperatively referred for embolization were retrospectively analyzed. Glubran (n = 40) and PVA (n = 55) were used to devascularize tumors. Sixty-two patients were not embolized because of dangerous anastomosis or other tumor characteristics. Intraoperative blood loss, intraoperative time, degree of angiographic devascularization and embolization-related complications were analyzed. RESULTS The intraoperative blood loss and operative time were significantly lower in the Glubran-embolized versus non-embolized group. Furthermore, Glubran embolization significantly reduced intraoperative blood loss and operative time for meningiomas that received their primary blood supply from the ICA and/or VA compared with PVA embolization. CONCLUSIONS Preoperative meningioma embolization with Glubran decreases intraoperative blood loss and operative time. Furthermore, embolization with Glubran produces more effective devascularization compared with PVA for meningiomas supplied by the ICA and/or VA. Thus, Glubran may represent a better embolic agent for this meningioma subtype.

Abstract
BACKGROUND/AIMS Prior studies demonstrated that pro-inflammatory cytokines (PICs) including IL-1β, IL-6 and TNF-α contribute to regulation of epilepsy-associated pathophysiological processes in the specific brain regions, namely the parietal cortex, hippocampus and amygdala. Moreover, GABA transporter type 1 and 3 (GAT-1 and GAT-3) modulating extracellular GABA levels are engaged in the role played by PICs in epileptogenesis. Note that brain ischemic injury also elevates cerebral PICs. Thus, in this report we examined the effects of nefiracetam (NEF), a pyrrolidone derivative, on the levels of IL-1β, IL-6 and TNF-α, and expression of GAT-1 and GAT-3 in the parietal cortex, hippocampus and amygdala using a rat model of post-ischemic nonconvulsive seizure (NCS). METHODS NCS was evoked by the middle cerebral artery occlusion (MCAO). ELISA and Western Blot analysis were employed to determine the levels of PICs and GAT-1/GAT-3, respectively. RESULTS MCAO significantly increased IL-1β, IL-6 and TNF-α in the parietal cortex, hippocampus and amygdala as compared with sham control animals (P<0.05 vs. control rats). Also, in these specific brain regions expression of GAT-1 and GAT-3 was amplified; and the levels of GABA were decreased in rats following MCAO (P<0.05 vs. control rats). Systemic administration of NEF significantly attenuated the elevated PICs, amplified GAT-1 and GAT-3 as well as impaired GABA. NEF also attenuated the number of NCS events following MCAO. CONCLUSION our data demonstrate that NEF improves post-ischemia evoked-NCS by altering PICs, GABA transporters thereby alleviating GABA in the parietal cortex, hippocampus and amygdala. This support a role for PICs and GABA in engagement of the adaptive responses associated with epileptic activity, but also suggests that NEF has anti-epileptic effects via PICs-GABA mechanisms, having pharmacological implications to target the specific PICs for neuronal dysfunction and vulnerability related to post-ischemic seizures and cognitive impairment.

Abstract
MicroRNAs are very small endogenous RNA molecules that play a crucial role in an array of biological processes, including regulation of skin morphogenesis. The microRNA let-7b is thought to modulate animal hair growth, by binding target genes that encode growth factors. Fibroblast growth factor 5 (FGF5) has been previously reported to be involved in the initiation of the catagen phase of hair growth. In this study, we combined previous reports with bioinformatic analysis techniques to identify and validate FGF5 and, using lucerifase assay, confirmed targeted binding of let-7b to FGF5. To investigate the interaction between let-7b and FGF5, alpaca skin fibroblasts were transfected with let-7b over-expression vectors, and then mRNA and protein expression levels of FGF5 and the gene encoding its receptor, FGFR1, were evaluated. Levels of FGF5 mRNA and protein were remarkably lower in transfected groups, as compared to controls. In summary, this study confirmed that let-7b acts as a regulator of skin morphogenesis, by directly targeting FGF5 and down-regulating its expression. It provides the evidence of hair growth regulated by miRNAs in animals and may have important applications in wool production.

Abstract
OBJECTIVE Because the formation of associated aneurysms (AAs) related to the characteristics of cerebral artriovenous malformations (cAVMs) is poorly recognized, the purpose of this study was to identify the responsible characteristics of cAVMs related to the formation of AAs and to identify patients with responsible characteristics related to the formation of AAs through the analysis of the outcomes of these patients after treatment. METHODS This study was performed to analyze the baseline characteristics of patients with cAVMs and AAs. The recurrent AA and residual size of cAVMs were used to evaluate the outcomes of patients after treatment. At the same time, the ROC curve was measured to gauge the relationship between the residual size of cAVMs and recurrent AAs in eligible patients. RESULTS Fifty (15.0%) patients with cAVMs and AA were confirmed; these patients had twice the hazard of hemorrhage as patients with only isolated cAVMs. An infratentorial location (P < 0.001) and fistula (P = 0.002) were independent predictors of the formation of AAs. After a mean 22.7 months follow-up, 2 patients developed recurrent AAs, and the annual recurrence rate for patients with responsible characteristics was 17.6%, but for all patients was 7.2%. The ROC curve showed that patients, specifically patients with responsible characteristics, the residual size of the cAVM was closely related to recurrent AA (area = 0.89, 95% confidence interval 0.81-0.97, P = 0.023, cut-off value = 82.5%). CONCLUSIONS Patients with cAVMs and AA who harbor a fistula or an infratentorial location tend to form AAs. To prevent recurrent AAs and decrease the subsequent risk of hemorrhage, complete obliteration of cAVMs or retrograding over 80% size of cAVMs is recommended.

Abstract
The aim of the present study was to analyze the feasibility, rate of procedure-related complications and midterm angiographic follow-up outcomes using the Enterprise (EP) and Solitaire™ AB (ST) stents in the stent-assisted coiling of intracranial aneurysms. In total, 81 patients with 90 aneurysms were included in the study, with the aim to treat 43 aneurysms with the EP stent (47.8%) and 47 aneurysms with the ST stent (52.2%). The 90 aneurysms were successfully stented and subsequently coiled; however, in four patients undergoing treatment with the EP stent, the stent was not navigable; thus, treatment with the ST stent was employed (EP, n=39, 43.3%; ST, n=51, 56.7%). Of the 90 aneurysms, 44 cases were ruptured aneurysms, with 74 located in the anterior circulation and 16 located in the posterior circulation. The stenting success rate of the ST stent was significantly higher compared with the EP stent. However, no statistically significant differences were observed with regard to the packing density, complete occlusion, progressive occlusion, recurrence rate, procedure-related complications, in-stent stenosis and stent migration rates between the two groups. In conclusion, the two common medical devices used for intracranial aneurysms are relatively safe and effective for the treatment of intracranial aneurysms. However, due to the higher stenting success rate of the ST stent, this medical devise was demonstrated to be more flexible and feasible compared with the EP stent.

Abstract
BACKGROUND Isolated dissecting aneurysms of the posterior inferior cerebellar artery (PICA) are rare lesions, which carry high risk of rebleeding and mortality. However, the existing literature concerning predictors of outcome after endovascular treatment is limited and controversial. Our present study retrospectively reviewed and analyzed the clinical outcome of endovascular treatment-ruptured PICA-dissecting aneurysms and explored the predictors of outcome. METHODS We retrospectively reviewed 17 consecutive patients with ruptured PICA dissecting aneurysms that underwent endovascular treatment from January 2003 to January 2014. Nine patients underwent selective coiling, whereas 7 patients underwent parent artery occlusion and 1 patient underwent stent-assisted coiling. Follow-up outcomes were evaluated using the modified Rankin Scale. The clinical outcomes of patients were categorized as favorable (modified Rankin Scale [mRS] score 0-1) or unfavorable (mRS score 2-6). RESULTS Favorable outcomes (mRS score 0-1) were obtained in 13 of 17 patients. Post-treatment recurrence occurred in 1 patient with selective coiling in the 15-month follow-up, and the patient received stent-assisted coiling. The only patients with stent-assisted coiling developed PICA occlusion during follow-up. Aneurysm located in distal segment usually presented with intraventricular hemorrhage (P = .015). Hypertension, coexisting hydrocephalus, and time to operation (latter than 2 weeks) were associated with unfavorable outcome. CONCLUSIONS Endovascular treatment of isolated dissecting aneurysm of PICA had excellent clinical outcomes, hypertension, coexisting hydrocephalus, and time to operation (latter than 2 weeks), which were associated with unfavorable outcome. Long-term follow-ups are necessary to provide stronger conclusions.

Abstract
The purpose of this study was to analyze influencing factors associated with immediate angiographic results in intracranial aneurysms patients after endovascular treatment (EVT), providing theoretical evidence and guidance for clinical treatment of intracranial aneurysms. Totally 529 patients met the inclusive criteria, consisting of 338 males and 191 females. Gender; age; history of hypertension, diabetes, and smoking; intracranial atherosclerosis; rupture status, size and location, features of aneurysmal neck, shapes; vasospasm; treatment modality; and degree of aneurysm occlusion were all carefully and completely recorded. All data were investigated in univariate and multivariate logistic regression model to determine whether they were correlated with the degree of aneurysm occlusion. According to aneurysm size, aneurysms were classified as micro-miniature, miniature, and large aneurysms. There were 451 narrow-neck aneurysms and 78 wide-neck aneurysms. Totally 417 were regular and 112 were irregular. And 125 were un-ruptured aneurysms; 404 were ruptured aneurysms. The modalities of treatment were as follows: embolization with coil (n = 415), stent-assisted coil embolization (n = 89), and balloon-assisted coil embolization (n = 25). Univariate analysis showed that aneurysm size, feature of aneurysm neck, shape, and rupture status might affect the immediate occlusion after EVT. Multivariate logistic regression analysis indicated that ruptured aneurysm, tiny aneurysm, and wide-neck aneurysm were independent influencing factors of complete occlusion of intracranial aneurysm. Aneurysm rupture status, size, feature of aneurysmal neck, and shape might be the independent influencing factors of immediate angiographic results in intracranial aneurysm patients after EVT. Un-ruptured, micro-miniature, narrow-neck, and regular-shaped aneurysms were more probable to be occluded completely.

Abstract
BACKGROUND Management of intracranial basilar dissecting aneurysms has been controversial and challenging, and surgical and conservative treatments usually have a bad prognosis. Our study aimed at evaluating the outcomes of endovascular treatment for these lesions and exploring the predictors of favorable outcome. METHODS We retrospectively reviewed 50 consecutive patients with basilar dissecting aneurysms from January 2006 to January 2013. Twenty-four patients underwent stent-assisted coiling whereas 26 patients underwent conservative treatment. Follow-up outcomes were evaluated using modified Rankin Scale (mRS) score. RESULTS Of the patients treated with stent-assisted coiling, 20 patients had a favorable outcome (mRS score, 0-1), post-treatment recurrence occurred in 3 patients, 1 had rebleeding, and 2 had no rebleeding. Of the patients treated with conservative therapy (observation or anticoagulation), 10 patients had an unfavorable outcome, 2 patients with ruptured aneurysms developed rebleeding, and 8 patients had poor outcome because of infarct progression. Stent-assisted coiling group had a more favorable outcome than the conservatively treated group (83.3% versus 55.2%, P = .019). Initial complete obliteration was related to the favorable outcome in endovascular-treated group (P = .042). Stent placement was the only independent predictor of favorable outcome in the logistic regression analysis (P = .030; odds ratio = 5.828; 95% confidence interval, 1.192-28.503). CONCLUSIONS Patients with basilar artery dissecting aneurysms treated with stent-assisted coiling had a more favorable outcome than the conservatively treated patients. Stent placement and initial complete occlusion were the favorable factors in patients with basilar dissecting aneurysm.

Abstract
Previous studies on the association between sex hormone binding globulin (SHBG) level and risk of breast cancer in postmenopausal women reported conflicting results. A meta-analysis of prospective studies was performed to evaluate the association between SHBG level and risk of breast cancer in postmenopausal women. Pubmed (1980 to July 2014) and EMBASE (1988 to July 2014) were searched for eligible studies. Eligible studies were prospective cohort or nested case-control studies on the association between SHBG level and risk of breast cancer in postmenopausal women. Meta-analysis using random-effects model was performed to calculate the pooled risk ratios (RRs) with 95% confidence intervals (95% CIs). Of 946 studies identified, 26 prospective studies from 21 publications were finally included in the meta-analysis. In postmenopausal women, the pooled RR for breast cancer comparing highest with lowest categories of SHBG was 0.64 (95% CI 0.57-0.72, p<0.001, I(2)=6.5%). The pooled RRs were not obviously altered in the sensitivity analyses and subgroup analyses. In cumulative meta-analysis, a more significant association between SHBG level and risk of breast cancer in postmenopausal women was observed as evidence accumulated by publication year. There was no obvious risk of publication bias. High SHBG level is significantly associated with decreased risk of breast cancer in postmenopausal women, and it's a protective factor of breast cancer in postmenopausal women.

Abstract
PURPOSE Endovascular treatment is an attractive approach for the treatment of unruptured vertebral dissecting aneurysms, and includes internal trapping and stent-assisted coil embolization. However, the optimal therapy remains debatable. We reviewed our experience with both endovascular treatment modalities and compared the safety, efficacy, and short-term outcomes for each approach. MATERIALS AND METHODS We retrospectively reviewed 65 consecutive patients with unruptured vertebral dissecting aneurysms who underwent endovascular treatment between January 2003 and January 2014. 24 patients underwent endovascular internal trapping (group A) while 41 patients underwent stent-assisted coiling (group B). Thirteen patients underwent single stent with coiling while 28 patients underwent double or three stent-assisted coiling. Short-term outcomes were evaluated using the modified Rankin Scale. RESULTS A favorable clinical outcome was achieved in 58 of 65 patients. Procedure-related complications included ischemic symptoms (n = 6) and recurrence (n = 4). There was no statistical difference in modified Rankin Scale scoring between groups. Group A patients had more ischemia symptoms compared with group B patients (p = 0.043), Group B patients had higher recurrence rates compared with group A patients, but the difference had no statistical significance (p = 1.00). However, recurrence only occurred in patients who underwent stent-assisted coiling alone (p = 0.046). CONCLUSION Stent-assisted coiling for unruptured vertebral dissecting aneurysms may maintain artery patency. Multilayer disposition of stents with coils may decrease complications and facilitate aneurysm occlusion. Larger, prospective studies are necessary to determine the long-term outcomes of reconstructive therapy.

Abstract
OBJECTIVE This study aims to retrospectively investigate the contraceptive methods of different reproductive-aged women in two different regions of Yangzhou, China, to understand the changes of the contraceptive methods, and to analyze the targeted improvements of future informed choices of contraception and birth control, and reduce the occurrence of the unintended pregnancies. MATERIALS AND METHODS This study included 13,407 and 20,876 married reproductive-aged women (MCW) that were chosen from a city downtown and a county-level city, respectively, for the group-organized random sampling questionnaire survey. RESULTS There was a significant urban-rural difference in the choice of contraceptive methods in different MCW. The female choices of contraception were single; the accessibility of contraceptive supplies, and personalized services could improve the implementation rate of long-term contraceptive measures. The cooperation of male contraceptive responsibility was related to the education levels and enhanced male-female communication. CONCLUSIONS It was very important for urban and rural women with different ages to choose different contraceptive measures, suggesting that these choices require the development of different educational models towards women of different ages and regions. The accessibility to various aspects of counseling and contraceptive measures should be strengthened, meanwhile male participation should also be promoted to prevent unwanted pregnancies and to reduce the health hazards related to sexual activities.

Abstract
PURPOSE The recovery time of traumatic carotid-cavernous fistula-induced oculomotor nerve paresis (ONP) after endovascular embolization with detachable balloons has not yet been adequately evaluated. This study was performed to make a deep analysis of the factors, which affect the prognosis of ONP after endovascular treatment of traumatic carotid-cavernous fistula (TCCF). MATERIALS AND METHODS We retrospectively evaluated the clinical characteristics and the outcome of oculomotor nerve function in a series of 98 consecutive patients with ONP due to traumatic carotid-cavernous fistula which were endovascular treated with detachable balloons. Univariate analysis was applied to test the association between the time of ONP recovery and clinical variables. RESULTS Ninety-eight consecutive patients (62 males, 36 females, mean age 34.2±12.7years) having presented with ONP underwent endovascular treatment with detachable balloons were enrolled in this study. ONP was complete in 22 (22.4%) patients and partial in 76 (77.6%) patients. Ninety (91.8%) patients were successfully occluded by single-session endovascular embolization. Retreatments by transarterial routes had to be performed in 8 (8.2%) patients because of recurrent fistula having occurred within 4weeks after embolization. ONP was recovered completely in all the patients, among who 4 (4.1%) were treated with occlusion of internal carotid artery. Factors showing significant association with the recovery time of ONP were the location of the fistula (P=0.007), the degree of preoperative ONP (P=0.003), the number of detachable balloon used (P=0.000) and the length of ONP before endovascular treatment (P=0.000). CONCLUSION Endovascular treatment of traumatic carotid-cavernous fistula-induced ONP with detachable balloons is a safe and effective method. The length of ONP before endovascular treatment, the location of the fistula, the degree of preoperative ONP, the number of detachable balloons used were the statistically significant predictors of the length of ONP complete recovery.

Abstract
PURPOSE To explore the expression of the TRAV gene in peripheral blood mononuclear cells (PBMCs) and in tumor-infiltrating lymphocytes (TILs) in the patients with breast cancer using a DNA melting curve (FQ-PCR) technique for T cell receptor (TCR) alpha chain CDR3 spectratyping. Peripheral blood samples and tissue samples were obtained from thirty breast cancer patients. Total RNA was extracted from PBMCs and tumor tissues and then reverse transcribed into cDNA. FQ-PCR was used to amplify the human TCR alpha chain CDR3 region with the primers to the TRAV and TRAC genes. TCR alpha chain CDR3 spectratyping and partial CDR3 sequencing were used to determine use of TRAV gene product in T cell responses. TCR alpha CDR3 spectratyping showed preferential usage of certain TRAV genes in the PBMCs and TILs of all patients with breast cancer. The frequencies of TRAV1.1, TRAV9, and TRAV29 exceeded 30% in PBMCs and the frequencies of TRAV1.1 and TRAV22 exceeded 30% in TILs. More than three quarters of the patients (23/30) overexpressed the same gene in both PBMCs and TILs; for example, patient-1 highly expressed TRAV9 in the PBMCs and TILs. Patients with positive or negative tumor markers of estrogen receptor (ER), progesterone receptor (PR), pS2, C-erbB-2, nm23, P53, and Ki-67 showed no significant common TRAV gene expression, but some TRAV gene preferential usage frequencies exceeded 20%. For example, five of seven patients positive for ER had high levels of expression of TRAV1.1 and TRAV3. Finally, the amino acid sequence of TCR CDR3 region showed some common motifs in some of the patients. CONCLUSIONS TRAV gene expression was complex and diverse in the patients with breast cancer. The TRAV gene usage may be closely related to the diversity of breast tumor antigens and the differential immune responses observed in individual patients. Research into the immunological mechanism of T cells may provide guidance for individual T cell-directed therapy for breast cancer.
