Abstract
Objective: To explore disease characteristics of primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) and compare the differences between PSC with and without IBD. Methods: Study design was cross sectional. Forty-two patients with PSC who were admitted from January 2000 to January 2021 were included. We analyzed their demographic characteristics, clinical manifestations, concomitant diseases, auxiliary examination, and treatment. Results: The 42 patients were 11-74(43±18) years of age at diagnosis. The concordance rate of PSC with IBD was 33.3%, and the age at PSC with IBD diagnosis was 12-63(42±17) years. PSC patients with IBD had higher incidences of diarrhea and lower incidences of jaundice and fatigue than in those without IBD (all P<0.05). Alanine aminotransferase, total bilirubin, direct bilirubin, total bile acid and carbohydrate antigen 19-9 levels were higher in PSC patients without IBD than in those with IBD (all P<0.05). The positive rates for antinuclear antibodies and fecal occult blood were higher in PSC patients with IBD than in those without IBD (all P<0.05). Patients with PSC complicated with ulcerative colitis mainly experienced extensive colonic involvement. The proportion of 5-aminosalicylic acid and glucocorticoid application in PSC patients with IBD was significantly increased compared with that of PSC patients without IBD (P=0.025). Conclusions: The concordance rate of PSC with IBD is lower at Peking Union Medical College Hospital than in Western countries. Colonoscopy screening may benefit PSC patients with diarrhea or fecal occult blood-positive for early detection and diagnosis of IBD.

Abstract
Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Abstract
Objective: To investigate the predictive value of the monocyte-to-lymphocyte ratio (MLR) for survival in patients with hepatitis B-related acute-on-chronic liver failure (HBV-ACLF). Methods: 92 cases with HBV-ACLF who were admitted to the General Hospital of Western Theater Command from October 2014 to October 2017 were selected. Clinical indicators were retrospectively collected, and their survival condition was followed up for 90 days, with the end point as death or liver transplantation. MLR levels predictive value among patients after 90 days of involvement was compared by analyzing the differences between the survival and death groups and its correlation with various indicators of liver function for prognosis. Results: 92 cases were included in this study, with a 90-day survival rate of 52% (48/92), and a mortality rate of 48% (44/92). MLR for survival and death groups were 0.520 (0.310, 0.828) and 0.740 (0.440, 1.120), respectively. MLR level was significantly higher in the death than survival group (P<0.05). Receiver operating characteristic curve (ROC) analysis showed that the area under the ROC curve (AUC) and 95% confidence interval for the survival group was 0.640 (0.527-0.754). The cutoff value for MLR was 0.399 at which the sensitivity and specificity were 0.864 and 0.396, respectively. Survival analysis showed that the 90-day survival rate was significantly lower in the high MLR group than corresponding low MLR group (P=0.011). Logistic multivariate regression analysis showed that after adjusting for other factors, MLR level was an independent prognostic factor in patients with HBV-ACLF. Conclusions: MLR can be used as a potential prognostic indicator for patients with HBV-ACLF, and its clinical value needs to be verified by large-scale prospective randomized trials.

Abstract
Abstract
Introduction
The residual SYNTAX score (rSS) as the SYNTAX remaining after completion of percutaneous coronary intervention (PCI) was proved to be related to poor outcomes.
Purpose
This study aimed to investigate the association of culprit-plaque morphology with rSS and the predictive value of rSS for major adverse cardiac events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI).
Methods
A total of 274 STEMI patients undergoing preintervention optical coherence tomography examination were included and divided into 3 groups – rSS=0 (n=72), 0<rss≤8>8 (n=68). Baseline clinical data and culprit-plaque characteristics were compared. MACE was defined as the composite of all-cause death, recurrence of myocardial infarction (MI), stroke and unplanned revascularization of any coronary artery.
Results
There was a significant difference in the prevalence of plaque ruptures, lipid-rich plaques, and calcification among the three groups (plaque rupture: 44.4% versus 59.0% versus 64.7%, lowest to highest rSS, p=0.04; lipid-rich plaque: 40.3% versus 54.5% versus 69.1%, lowest to highest rSS, p=0.003; calcification: 38.9% versus 52.5% versus 61.8%, lowest to highest rSS, p=0.024). Multivariate logistic regression analysis indicated that rSS>8 was an independent predictor for plaque rupture (OR: 2.21, 95% CI: 1.19–4.19, P=0.013). During a mean follow-up of 2.2 years, MACE occurred in 47 (17.2%) patients. In fully adjusted analyses, rSS was independently associated with MACE (HR: 1.06, 95% CI: 1.02–1.10, P=0.005); patients with rSS >8 had higher MACE risk compared to rSS=0 (HR: 2.68, 95% CI: 1.11–6.5, P=0.029).
Conclusion
In STEMI patients, culprit-plaque morphology was significantly correlated with rSS, and elevated rSS was independently associated with cardiovascular risk.</rss≤8>

Abstract
Objective: Clinicopathological characteristics of neuroendocrine neoplasms are highly heterogeneous based on variable origins.Our study aims to explore the clinical features of rectal neuroendocrine neoplasm (RNEN). Methods: Patients with histologically diagnosed rectal neuroendocrine neoplasms were retrospectively analyzed between January 2012 and December 2020. Epidemiological characteristics, clinical manifestations, complete blood count, endoscopy findings, and pathological features were recorded and analyzed. T-test was used for measurement data analysis, Chi-square test was performed for classification data analysis, and Binary logistic regression was applied for analyzing risk factors of metastasis. Results: Among 172 patients, the male to female ratio was 107 to 65 with an average age of (52±12) years (16-77 years). Altered bowel habit was the most common initial symptom (58/172, 33.7%), followed by abdominal pain (36/172, 20.9%) and loss of body weight (27/172, 15.7%). One hundred and sixty-one cases were neuroendocrine tumors, 9 were neuroendocrine carcinomas and 2 were mixed neuroendocrine-non-neuroendocrine neoplasms. Most endoscopic presentations were polypoid lesions (147/172, 85.5%), mainly limited to mucosa (48/172, 27.9%) and submucosa (96/172, 55.8%). Twenty-nine patients developed lymph node invasion or distant metastasis at diagnosis. There were statistical difference of neutrophil-to-lymphocyte ratios (NLR) among groups with different tumor size (<10 mm vs. 10-20 mm vs.>20 mm, mean NLR 1.79±0.55 vs. 2.27±1.23 vs. 2.95±0.66, P<0.01. Compared with non-metastatic group, the metastatic group presented higher NLR(2.61±0.81 vs. 1.89±0.80, P<0.01). Tumor size (<10 mm vs. 10-20 mm vs.>20 mm, OR 1.00 vs. 2.10 vs. 5.25×109, P =0.001), invasion to bowel wall (mucosa vs. submucosa vs. muscularis vs. serosa invasion,OR 1.00 vs. 3.26 vs. 14.11 vs. 39.42, P=0.008), and NLR (NLR<2.25 vs. NLR≥2.25, OR 1.00 vs. 5.19, P =0.024) were risk factors for metastasis. Conclusion: Metastasis of RNEN is related with tumor size, degree of bowel invasion and NLR. High NLR is a poor prognostic factor of RNEN.

Abstract
Objective: To analyze the time point when patients with fatty liver disease had a significantly higher risk of elevated fasting blood glucose than those without in the physical examination group in Karamay Central Hospital, factors affecting the incidence of elevated blood glucose in patients with fatty liver disease, and the influence of the number of influencing factors on it. Methods: Physical examination data from Karamay Central Hospital during September 2008 to April 2017 were retrospectively analyzed. Combined with the survival analysis, the 1-,3-, 5-, and 7-year prevalence rates of elevated fasting glucose occurs in people with and without fatty liver disease were analyzed. Z-test was used to compare the survival rate difference at each time point. Cox regression model was used for multivariate analysis. Results: 10 802 people were in the fatty liver group. The elevated fasting blood glucose incidence density was 61/1 000 person-years, and the 1-, 3-, 5-, and 7-year prevalence rates were 2%, 16%, 28%, and 38%, respectively. 29 579 people were in the non-fatty liver group. The elevated fasting blood glucose incidence density was 23/1000 person-years, and the 1-, 3-, 5-, and 7-year prevalence rates were 1%, 7%, 11%, and 16%, respectively. The short-term and long-term elevated fasting blood glucose incidence risk were significantly higher in fatty liver group than non-fatty liver group(P < 0.001). The elevated fasting blood glucose incidence risk was apparently higher in fatty liver group than that of non-fatty liver group from the first year onward (P < 0.001). Age≥50 year's old (HR = 1.954, 95% CI :1.792-2.132), elevated body mass index (HR = 1.397, 95% CI : 1.198-1.629), blood pressure (HR = 1.284, 95% CI : 1.181-1.397), triglycerides (HR = 1.171, 95% CI: 1.077-1.274) were independent risk factors, which promoted the elevated fasting blood glucose incidence risk in patients with fatty liver disease. Fatty liver combined with the above 2, 3, and 4 risk factors had apparently increased the incidence risk of elevated fasting blood glucose (P < 0.001). Conclusion: People with fatty liver disease had a higher risk of elevated fasting blood glucose from the first year than those without. Age≥50 year's old, elevated blood pressure, body mass index and triglyceride might increase risk of elevated fasting blood glucose in patients with fatty liver disease, combined with the above 2,3 or 4 risk factors can increase the risk of elevated fasting blood glucose.

Abstract
Objectives: To compare the impact of ticagrelor or clopidogrel on serum uric acid levels among patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and further evaluate the effects of variation of serum uric acid levels on platelet reactivity. Methods: STEMI patients who admitted to Fuwai Hospital from April 2017 to January 2020, and underwent primary PCI and discharged alive with aspirin and ticagrelor or clopidogrel were included in this study. Patients were divided into ticagrelor group and clopidogrel group. The baseline clinical data were collected. Serum uric acid and creatinine levels at baseline and 30 days post-PCI were measured. Light transmittance aggregometry was used to assess maximum aggregation rate induced by adenosine diphosphate and arachidonic acid. The changes of serum uric acid and creatinine were compared between the two groups. Multivariate logistic regression was performed to evaluate independent related factors for rise in the uric acid levels, and the effect of variation of serum uric acid level on platelet reactivity was analyzed. Results: A total of 967 patients were included, the age was (59.4±12.1) years, and 163 case were female. There were 550 cases in ticagrelor group (56.9%) and 417 cases in clopidogrel group (43.1%). Baseline serum uric acid and creatinine levels were similar between the 2 groups. At 30 days, the serum uric acid level [(347.2±96.5) mmol/L vs. (341.2±105.3) mmol/L, P=0.009] and absolute [46.4 (-2.4, 88.1) mmol/L vs. 25.0 (-21.9, 73.0) mmol/L, P=0.001] and percentage [13.2 (-0.01, 29.0) % vs. 7.9 (-5.7, 25.0) %, P=0.007] increase in the serum uric acid levels were significantly higher in ticagrelor group than in clopidogrel group. The level of serum creatinine at 30 days was significantly lower in ticagrelor group than in clopidogrel group [(89.7±21.3) μmol/L vs. (94.4±43.9) μmol/L, P<0.05], whereas there were no differences in absolute [8.0 (-1.4, 16.6) μmol/L vs. 7.8 (-2.0, 16.6) μmol/L] and percentage [10.5 (-1.7%, 22.6%) vs. 9.8 (-2.4%, 22.1%)] change in the serum creatinine between the 2 groups (all P>0.05). Logistic regression analysis showed that, after adjusting for confounding factors, ticagrelor therapy was an independent related factor of serum uric acid elevation (OR=1.582, 95% CI:1.023-2.447, P=0.039). The variation of the serum uric acid levels did not affect platelet aggregation and the percentage of high platelet reactivity in both groups. Conclusions: Ticagrelor use is related to a significant increase in the serum uric acid levels at 30 days post-PCI in this patient cohort. The variations in the uric acid levels do not increase the percentage of high platelet reactivity in STEMI patients treated with ticagrelor or clopidogrel.

Abstract
Objective: To investigate the association between postprocedural D-dimer, high sensitivity C-reactive protein(hs-CRP) and low-density lipoprotein-cholesterol(LDL-C) and outcomes of acute myocardial infarction (AMI) patients treated by percutaneous coronary intervention(PCI), in order to clarify the impacts of thrombotic, inflammatory and cholesterol risks on long-term prognosis. Methods: Patients with AMI who underwent emergency PCI from January 2010 to June 2017 in Fuwai Hospital with complete baseline data were enrolled. Patients were stratified into four groups according to quartiles of D-dimer, hs-CRP and LCL-C. Cox regression was used to analyze the relationship between these biomarkers and prognosis. Restricted cubic spline (RCS) was used to characterize the continuous association between risk of all-cause death and biomarkers. The primary outcome was all-cause death. Results: A total of 3 614 patients were included in the analysis. The age was (59.2±12.0) years old, and 2 845 (78.7%) were male and 3 161 (87.5%) patients were diagnosed as ST-segment elevation myocardial infarction. The follow-up time was 652 (414, 1 880) days. Survival analysis showed that postprocedural D-dimer and hs-CRP were significantly associated with all-cause mortality (all P<0.05). Cox regression with multiple adjustments showed that patients with D-dimer≥580 μg/L presented higher risk of all-cause death (HR=2.03, 95%CI 1.22-3.38, P=0.006), compared to patients with D-dimer<220 μg/L. RCS analysis showed that risk of all-cause death was stably high when D-dimer reached 500 μg/L. Multivariable Cox regression also showed that patients with hs-CRP<2.74 mg/L (HR=1.86, 95%CI 1.10-3.15, P=0.020)or hs-CRP≥11.99 mg/L (HR=2.14, 95%CI 1.35-3.40, P=0.001) presented higher mortality compared to patients whose hs-CRP was 2.74-7.18 mg/L. RCS analysis indicated a J-shaped relation between hs-CRP and mortality, as greater risk of death was observed when hs-CRP was lower than 2 mg/L or higher than 10 mg/L. LDL-C was not associated with outcomes (all P>0.05). Conclusions: Postprocedural D-dimer is significantly associated with long-term prognosis of AMI patients treated by PCI. Patients with extremely high or low levels of hs-CRP presents worse outcomes. Intensive and tailored antithrombotic or anti-inflammatory therapies should be considered for patients with increased thrombotic risk and those with extremely high or low inflammatory risk.

Abstract
OBJECTIVE To construct swept source optical coherence tomography (SS-OCT) imaging system for root canal endoscopy, and to evaluate the accuracy of diagnosing artificial root fractures. METHODS An ultra-high-speed (40 kHz) swept laser source was developed based on the piezoelectric tuning filter and the Fourier domain mode locking (FDML) swept laser technology (patent number: 200620135940.2). Ultra-miniature gradient index lens technology (patent number: 201320241218.7) was used to create a thin endoscopic probe with a diameter of 0.86 mm for real-time image transmission. The SS-OCT light source had a wavelength of 1 310 nm and a bandwidth of 100 nm. The axial and transverse image resolutions were 15 μm and 25 μm, respectively. Artificial fractures were created on human mandibular premolars with single root and the premolar roots were prepared to 41 horizontal sections (1 mm thick). 27 root sections with fractures (width: 52-284 μm) and 14 the sections without fractures were observed under an optical stereomicroscope with a cold light source as the gold standard. The horizontal root sections were scanned by self-developed SS-OCT imaging system for root canal endoscopy with a central wavelength of 1 310 nm and bandwidth of 100 nm. The data were reconstructed with 30 μm thick slices at an interval of 30 μm. Two observers, a radiologist and an endodontist, were trained and independently evaluated all the reconstructed images blindly. The diagnostic performance of SS-OCT imaging system was calculated, and statistical analysis was performed. RESULTS SS-OCT root canal endoscopic imaging system composed of high-speed swept laser source, fiber coupler, endoscopic probe, reference arm and differential detector. Root sections could be scanned by SS-OCT and imaged in realtime at a depth of 1 to 2 mm. The kappa value for interobserver agreement was 0.792, and the intraobserver agreement was 1.000 and 0.709 for two observers respectively. All of 27 fractured root sections and 12 of 14 root sections without fractures were accurately diagnosed while 2 unfractured root sections were misdiagnosed. The sensitivity was 1.000 and the specificity was 0.857 for diagnosis of artificial root fractures by SS-OCT. The positive predictive value (PPV), negative predictive value (NPV) and the overall accuracy rate were 0.931, 1.000 and 0.951 respectively. CONCLUSION The swept source optical coherence tomography imaging system for root canal endoscopy is a promising imaging method for observing root fractures..

Abstract
Objective: To investigate the effects of probiotics and synbiotics on inflammation and microbiota of acute colitis in mice. Methods: C57BL/6J mice were divided into 4 groups randomly. Each group had 10 mice and was given 2.5% dextran sulfate sodium (DSS) drinking water for 5 days other than the blank control group. Except for model control group, other two groups were administrated with probiotics and synbiotics, respectively. Probiotics was composed of Lactobacillus acidophilus, Lactobacillus rhamnosus and Bifidobacterium lactis, while synbiotics was composed of the aforementioned probiotics, inulin and galactooligosaccharide. Feces of different periods and mucosa samples were collected to analyze the differences of enteric flora by 16s rDNA sequencing. Results: (1) Pathological scores in probiotics group and synbiotics group were 5.40±2.79 and 7.25±2.87, respectively, which were significantly lower than those in the model control group with scores 27.00±7.94. Model control group, probiotics group and synbiotics group showed lower flora diversity, increased Bacteroides and decreased Faecalibacterium than blank control group. The mucosal microbiota was different from fecal flora in abundance and species for each group, and Mucispirillum was more common in mucosa. Conclusions: Probiotics and synbiotics alleviate the inflammation of acute colitis in mice. Imbalance of beneficial genera to harmful genera is the characteristic of acute colitis. Supplementation of probiotics and synbiotics contributes to regulating the balance of intestinal microbiota.

Abstract
Objective: To investigate the impact of immediate cessation of antiviral therapy on postpartum liver function and the factors influencing postpartum abnormality in mothers with chronic hepatitis B virus infection. Methods: A retrospective cohort study was conducted. One hundred eighty-eight pregnant women with HBV DNA level > 2×106 IU/ml were enrolled from June 2014 to June 2018. Demographic information and clinical data of liver function and HBV DNA load during gravidity, intrapartum and postpartum period were collected. According to the antiviral treatment recommendations during pregnancy, the women were divided into three groups, namely, tenofovir (TDF), telbivudine (LdT) and control group. Liver function abnormalities among the three groups were compared within 6 months after delivery, and the factors influencing abnormal liver function were analyzed by unconditional logistic regression. Results: Of the 188 cases, 72 cases were in the TDF group, 80 cases in the LdT group, and 36 cases in the control group. Pregnant women in the TDF and LdT groups received oral TDF (300 mg/d) and LdT (600 mg/d) from 28 ± 4 weeks of gestation till delivery. Among the 188 patients, 30 (16.0%) had abnormal postpartum liver function abnormality. The incidence of postpartum liver function abnormality [alanine aminotransferase (ALT) > 2 × upper limit of normal (ULN)] in the TDF, LdT, and control groups was 19.4%, 12.5%, and 16.7%, respectively. The postpartum peak levels of ALT (median, range) in the three groups were 34.5 (12.0-946.0) U/L, 37.5 (12.0-733.8) U/L, and 39.0 (7.0-513.0) U/L, respectively. There was no significant difference between the two indexes among the three groups (P > 0.05). There was no statistically significant difference in the degree of postpartum liver function abnormalities between the three groups (P = 0.944). Most of the liver function abnormalities were mild to moderate (2 × ULN≤ALT < 10 × ULN), and usually resolved spontaneously or by treatment. Univariate and multivariate analysis showed that baseline ALT level during pregnancy was an independent factor associated with postpartum liver function abnormality (OR = 1.031, CI 95%: 1.005-1.058; χ(2) = 5.340, P = 0.021), whereas age, antiviral therapy, HBeAg-positivity, baseline HBV DNA levels, gravidity, parity, preterm delivery and delivery mode were not significantly associated with postpartum liver function abnormality. Conclusion: Cessation of antiviral therapy after delivery did not significantly increase the risk of postpartum liver function abnormality in pregnant women with chronic HBV infection. The ALT level during pregnancy is a factor influencing postpartum liver function abnormality.

Abstract
Objective: To evaluate the diagnostic value of capsular endoscopy in patients with obscure gastrointestinal bleeding (OGIB) in different age groups, and assess its effectiveness and safety. Methods: A total of 216 patients who were diagnosed with OGIB between March 2005 and March 2016 at Department of Gastroenterology of Peking Union Medical College Hospital were retrospectively reviewed. They were assigned into three groups: young adults, middle-aged and elderly. The demographic characteristics, clinical manifestations, working performance as well as endoscopic features in each group were collected and analyzed. Results: The detection rate and diagnosis rate of the young adults and middle-aged group were 98.53% vs 98.51% (P=0.992), 92.65% vs 91.04% (P=0.734), while those between the young adults and the elderly group were 98.53% vs 91.14% (P=0.109), 92.65% vs 87.34% (P=0.289), and 98.51% vs 91.14% (P=0.113) and 91.04% vs 87.34 (P=0.475) between the middle-aged and elderly group. No significant difference existed in either detection rates nor diagnostic rates between the different age groups. The distribution of the small intestinal lesions varied between the different age groups. The top three common lesions in young adults were vascular malformation, small intestine ulcer and Crohn's disease, while in the middle-aged group vascular malformation, non-specific enteritis and small intestine ulcer were the most common. Patients in elderly group were most likely to have vascular malformation, small intestine ulcer and erosion. Conclusions: For patients of any age with OGIB, capsule endoscopy is a safe, effective and comfortable examination which can be widely used in clinical practice.

Abstract
Objective: To investigate the correlations between gastric Helicobacter pylori (Hp) infection and colorectal polyps or cancer. Methods: Among patients who finished colonoscopy exams in Peking Union Medical College Hospital (PUMCH) between May 2012 and May 2017, 3 483 patients were diagnosed with colorectal polyps, 135 patients with newly diagnosed colorectal cancer. A total of 1 925 healthy subjects were enrolled as normal controls. Gastric rapid urease tests (RUT) were done in all patients. General clinical data, RUT results, sizes and numbers of polyps, cancer location were analyzed. Results: The proportion of Hp infection in patients with colorectal polyps was 31.5%, higher than that in healthy controls. The odds ratio (OR) of Hp infection in polyp group was 1.17 (95%CI 1.04-1.32) after age and gender were adjusted. The Hp infection rate in patients with polyps over or equal to 1 cm was significantly higher than that in patients with polyps smaller than 1 cm. Patients with more than 1 polyps presented a higher rate of Hp infection than patients with only 1 polyp. Hp infection rate in patients with colorectal cancer was 36.3%, with the adjusted OR 1.56 (95%CI 1.06-2.30). The location of colorectal cancer was not correlated with Hp infection. Conclusions: Gastric Hp infection is more common in patients with colorectal polyps than in healthy controls. Polyps ≥1 cm, multiple polyps and colorectal cancer are correlated with higher rates of Hp infection. Cancer location is irrelevant to Hp infection.

Abstract
Objective: To explore the application value of computed tomography angiography (CTA) and three-dimensional reconstruction in repairing high-voltage electrical burn wounds in necks, shoulders, axillas, and upper arms with tissue flaps. Methods: From December 2014 to December 2018, 12 patients with high-voltage electrical burns in necks, shoulders, axillas, and upper arms were hospitalized. The size of wounds ranged from 13 cm×10 cm to 32 cm×15 cm after complete debridement. Before tissue flap repair, the subclavian artery-axillary artery-brachial artery and their branches were examined by CTA. The main target vessels and their branches were conducted by three-dimensional reconstruction, and the development of the axis vessels for the tissue flaps planning to dissect and their branches were observed. For wounds in upper arms, amputation stump bone exposed wounds, and wounds in axillas and the anterior, the latissimus dorsi myocutaneous flap is the first choice for repair, if the thoracodorsal artery and internal and external branches are well developed according to CTA examination. Latissimus dorsi myocutaneous flaps were used in 6 patients with the area of myocutaneous flap ranging from 16 cm×12 cm to 32 cm×17 cm. All the donor sites were covered by split-thickness skin graft of thighs. For large wounds in occiputs, necks, and scapulas, the contralateral lower trapezius myocutaneous flap is the first choice for repair, if the superficial descending branch and deep branch of the contralateral transverse cervical artery are well developed according to CTA examination. For small wounds in necks and scapulas, the ipsilateral lower trapezius myocutaneous flap can be used for repair, if the superficial descending branch of the ipsilateral transverse cervical artery is well developed according to CTA examination. Lower trapezius myocutaneous flaps were used in 4 patients with the area of myocutaneous flap ranging from 18 cm×12 cm to 25 cm×17 cm. The donor site of one patient was sutured directly and the donor site of the other 3 patients was covered by split-thickness skin graft of thighs. For wounds in the posteromedial side of upper arms and the anterior side of axillas, the lateral thoracic skin flaps can be used for repair, if the latissimus dorsi myocutaneous flap can not be utilized for reasons of back burn or no muscle is needed for dead space, when the blood supply of side chest skin is reliable according to CTA examination. Lateral thoracic skin flaps were used in 2 patients with the area of skin flap ranging from 16 cm×12 cm to 17 cm×14 cm. The donor site of one patient was sutured directly and the donor site of the other one patient was covered by split-thickness skin graft of thigh. Results: During the operation of tissue flap repair in 12 patients, the orientation and starting position of the axis vessels were consistent with those observed by CTA examination before operation. All the tissue flaps survived after operation. During follow-up of 1 to 24 months, the patients were satisfied with no serious scar contracture affecting the function nor secondary infection or chronic ulcer. Conclusions: CTA and its three-dimensional reconstruction technique can clearly reconstruct the subclavian artery-axillary artery-brachial artery and their branches before repair of high-voltage burn wounds in necks, shoulders, axillas, and upper arms. It can be used to observe whether the vessels are embolized or not and the starting position and orientation of blood vessels, which can provide an important reference for the selection of tissue flap transplantion.

Abstract
Objective: To investigate the clinical features and change trend of patients with acute coronary syndrome(ACS) undergoing emergent percutaneous coronary intervention(PCI). Methods: In this retrospective study, we retrieved all medical records of 4 907 ACS patients who underwent emergent PCI in Fuwai hospital from January 1,2010 to December 31,2016. We analyzed the clinical features and change trend in these patients. According to clinical diagnosis, patients were grouped as ST-elevated myocardial infarction(STEMI) group (3 719 cases) and NSTE-ACS group (patients with non-STEMI and unstable angina, 1 188 cases). Results: The ACS patients were aged (59.5±11.8) years old. There were 3 772 males and 1 135 females. The annual number of ACS patients underwent emergent PCI increased from 412 patients in 2010 to 1 067 patients in 2016. The number of NSTE-ACS patients increased from 11.4% (47/412) in 2010 to 26.5% (283/1 067) in 2016. Compared with STEMI group, patients in NSTE-ACS group were significantly older ((61.2±10.9) years old vs. (58.9±12.1) years old,P<0.01).The percent of female patients (30.1% (358/1 188) vs. 20.9% (777/3 719), P < 0.01), history of hypertension (69.1% (821/1 188) vs. 60.4% (2 248/3 719,P <0.01), previous PCI (25.8% (307/1 188) vs. 12.4% (461/3 719), P <0.01), and previous coronary artery bypass grafting (3.0% (36/1 188) vs. 1.0% (37/3 719), P <0.01) were all significantly higher in NSTE-ACS group than in STEMI group. On the other hand, NSTE-ACS patients presented less chronic renal failure (2.9% (35/1 188) vs. 4.3% (173/3 719), P <0.05) and hepatic dysfunction (8.5% (101/1 188) vs. 13.3% (495/3 719), P<0.01) as compared to ACS patients. In coronary angiography, NSTE-ACS patients had a higher prevalence of left-main disease (14.0% (166/1 188) vs. 7.8% (291/3 719), P<0.012 5) and triple vessel disease (47.8% (568/1 188) vs. 43.5% (1 619/3 719), P<0.012 5). There were no differences in prevalence of diabetes mellitus (31.9% (1 187/3 719) vs. 34.8% (414/1 188),P>0.05) and acute renal failure (0.1% (38/3 719) vs. 0.6% (7/1 188),P>0.05) between STEMI group and NSTE-ACS group. Conclusions: This single center retrospective analysis reveals that there is an increasing trend of NSTE-ACS patients from 2010 to 2016. Furthermore, there are more high-risk clinical characteristics in NSTE-ACS patients than in STEMI patients.

Abstract
This is a complicated and difficult case. The onset symptom of a 62-year-old male was recurrent intestinal obstruction. Ileocecal and ileocolic operation was done twice. Massive gastrointestinal bleeding occurred due to giant fistula of descending duodenum, which connected to ileocolic anastomosis. After consultation by multidisciplinary team, jejunal-feeding tube was placed to provide enteral nutrition. With general condition improving, duodenal fistula repair and involved bowel resection were performed. Postoperative pathology confirmed Crohn's disease. The patient was treated with thalidomide and recovered well during follow-up.

Methods: Patients with ACS in Fuwai hospital who were given ticagrelor after discharge between Jan. 2015 to Jun. 2015 were analyzed.The clinical characteristics and adherence to ticagrelor of these patients were collected by reviewing the electronic medical records and telephone interview.Date were statistically-analyzed. Results: Among all screened 404 patients, 158 (39.1%) patients prematurely stopped ticagrelor within 12 months, while 119(29.5%) patients switched from ticagrelor to clopidogrel.Unavailable locally (34.8%), economic reasons (17.7%) and hemorrhagic events (18.4%) were the main causes of the premature discontinuation of ticagrelor.Univariate analysis showed left main disease (P=0.04) and the frequency of outpatient follow-up (P<0.01) as relative factors for prematurely stopping ticagrelor outside hospital after discharge.Multivariate analysis revealed medical insurance payment (OR 1.79, 95%CI 1.03-3.11) and the frequency of outpatient follow-up (OR 0.61, 95%CI 0.43-0.86) as independent predictors of prematurely stopping ticagrelor outside hospital.Prematurely stopping ticagrelor has no significant effect on the ischemic events (myocardial infaction or stroke) (P=0.76). Conclusion: Social cinditions is the main factor for the persistence to ticagrelor among ACS patients after dischcrge.Medical insurance payment and low frequency of outpatient follow-up were independent predictors of prematurely stopping ticagrelor and it may not have impact on ischemic events.

Abstract
Objectives: To study an effects on hearing ability and speech performance of the patients with auditory neuropathy (AN) after cochlear implantation (CI). Methods: Thirty-five AN patients (26 males and 9 females) after CI in our center since 2007 were chosen, including 5 postlingual patients (implanted age from 14.3 to 38.6 years old) and 30 prelingual patients (implanted age from 1.1 to 13.7 years old). Hearing sensitivity and speech performance were estimated via following methods: (1) implanted hearing thresholds by sound field audiometry; (2) speech audiometry, including monosyllable, disyllable and sentences recognition test by computer-controlled software and sentence recognition test under noise condition (signal to noise ratio=+ 10dB); (3) Mandarin Early Speech Perception test (MESP), Mandarin Pediatric Speech Intelligibility test (MPSI), MAIS, or IT-MAIS for prelingual AN implantees. Results: The average implanted hearing threshold (250-4 000 Hz) was (41.1±11.7) dBHL in 22 AN implantees, while those prelingual implantees was (39.1±10.9) dBHL, and (44.9±12.3) dBHL in postlingual implantees. Speech audiometry were implemented in four of 5 postlingual AN implantees, the results showed increasing tendency in monosyllable recognition scores, dramatic individual variation in computer-controlled disyllable and sentences recognition test, and poor scores (<30%) in speech recognition test in noise condition. Four of 30 prelingual implantees reconstruct their speech recognition ability within 1-3 years after switch-on, characterized as recognition scores (>60%) in monosyllable, disyllable and sentences. The one of prelingual implantee gained recognition scores of speech in noise within 1 year after switch-on. MAIS or IT-MAIS were implemented in twenty-five prelingual implantees, the average score in these patients was 28.6±11.7. Conclusion: Cochlear implant can improve the hearing thresholds of AN patients, however, the improvement in speech performance presented significant variations among the implanted individuals.

Abstract
OBJECTIVE To explore the association between hypoxia-inducible factor 1α (HIF-1α) expression and lymph node metastasis in oral squamous cell carcinoma (OSCC). METHODS Tumor specimens from 125 patients with histologically-proven, surgically-treated OSCC were examined by immunohistochemical staining for expression of HIF-1α. The patients were divided into two groups by the expression of HIF-1α, high expression of HIF -1α group (H-group) and low expression of HIF-1α group (L-group). The main assessment parameters were lymph node metastasis rate and disease-specific survival (DSS). The lymph node metastasis rate and clinicopathologic features were compared using Mann-Whitney test. The Kaplan-Meier curve was generated for each group and compared using the log-rank test. Cox proportional hazard models were utilized for multivariate analyses of HIF-1α expression and other baseline factors with DSS. All calculations and analyses were performed using the SPSS 17.0 software package. RESULTS The protein expression levels of HIF-1α were up-regulated in OSCC and two patients were unable to evaluate. There were 48 patients in L-group and 75 patients in H-group. Lymph node metastasis rate was 37.5% (18/48) for L-group and 58.7% (44/75) for H-group (P=0.027). Expression of HIF-1α was significantly correlated with lymph node metastasis. The patients of L-group had a significantly better DSS than the patients of H-group (70.8% vs. 46.7%, P=0.005), while the patients of L-group had a significantly better disease-free survival (DFS) than the patients of H-group (60.4% vs. 36.0%, P=0.009) by Kaplan-Meier method. A multivariate survival analysis also showed that HIF-1α expression (HR=2.164, 95%CI: 1.150-4.074, P=0.017) and T-stage (HR=1.387, 95%CI: 1.066-1.804, P=0.015) both were the independent factors associated with prognosis. CONCLUSION HIF-1α expression is significantly correlated with lymph node metastasis in OSCC. HIF-1α expression is an independent predictive factor for prognosis of OSCC patients, and may serve as a potential biomarker for molecular diagnosis and targeted therapy in future.

Abstract
OBJECTIVE To compare the dosimetric differences between volumetric modulated arc therapy and intensity modulated radiotherapy for breast cancer patients after breast-conserving surgery. METHODS Ten patients who received radiotherapy after breast-conserving surgery were selected. Eclipse planning system was used to design volumetric rotating intensity-modulated (2F-RapidArc) and two field intensity-modulated radiation therapy (2F-IMRT) planning for each patient. 2F-RapidArc plans were made using two partial arcs with gantry rotation from 287°-293° to 152°-162°, and 0° to 90 ° was avoidance sector. The gantry angle of 2F-IMRT were 301°-311° and 125°-135°. The prescription dose was 46 Gy/23 fractions. All plans required 95% of the target volume receiving the prescription dose. The dose distribution of the target, organs at risk, machine unit (MU) and treatment time were compared. RESULTS 2F-RapidArc and 2F-IMRT plans' uniformity index was 1.12±0.02 and 1.11±0.03 (P=0.282), respectively; conformal index was 0.80±0.03 and 0.65±0.04 (P<0.001), respectively. V110 of plan target volume was 20.98%±14.47% and 10.43%±10.49% (P=0.030), respectively. Compared with the 2F-IMRT, 2F-RapidArc plans had a higher dosimetric parameters for left lung: V5 (48.06%±17.32% vs. 24.23%±6.56%,P=0.001), V10 (28.89±9.28 vs.17.07±4.78%,P=0.004), Dmean [(9.70±2.14) Gy vs. (6.86±1.77) Gy, P=0.002], increased the double lung: V5 (22.85%±7.55% vs. 11.01%± 2.95%,P=0.001), V10 (13.16%±4.33% vs. 7.76%± 2.16%, P=0.006), Dmean [(4.66±0.95) Gy vs. (3.17±0.82) Gy, P=0.001], reduced the left lung: V40 (3.58%±1.46% vs. 6.19%±3.04%, P=0.006), reduced the double lung: V40 (1.61%±0.64% vs. 2.81%± 1.39%,P=0.005), increased cardiac: V5 (39.3%±17.19% vs. 8.79%±4.24%, P<0.001), V10 (21.31%±13.8% vs. 5.73%±3.42%, P=0.002), V20 (7.80%±6.08% vs. 4.05%±2.85%,P=0.018), Dmean [(0.64±0.25) Gy vs. (0.29±1.39) Gy,P<0.001],reduced the heart: V40(0.50%±0.40% vs. 1.86%±1.94%,P=0.037),increased the contralateral breast Dmean [(1.63±1.26) Gy vs. (0.09±0.05) Gy, P=0.004]. Compared with 2F-IMRTplan, 2F-RapidArc increased the treatment time [(132.9±7.2) s vs. (140.3±11.6) s, P=0.030]. Both the machine units were almost the same [(467.0±30.4) MU vs. (494.7±44.9) MU, P=0.094]. CONCLUSION Both 2F-RapidArc and 2F-IMRT plans could reach the clinical requirements. 2F-RapidArc had a better conformal index, reduced the high dose area, but increased the low dose regions of the lung, heart, body area, and increased the average dose of the contralateral breast. The treatment time of 2F-RapidArc was longer than that of 2F-IMRT, and the MU of 2F-RapidArc and 2F-IMRT plans were almost the same.

Abstract
Objective: To observe the value of evaluating the coronary collateral circulation of chronic total occlusion (CTO) by transluminal attenuation gradient (TAG) and Rentrop grading, and analyze the influencing factors for coronary collateral circulation. Methods: A total of 179 CTO patients admitted to Beijing Anzhen hospital during June 2013 to August 2016 were included in this study.All patients received coronary computed tomographic angiography (CCTA) examination before coronary angiography.Finally, 75 patients (79 vessels) were enrolled.Patients were divided into two groups on the basis of Rentrop classification.The Rentrop 3 was defined as a well-developed coronary collateral circulation group, including 50 CTO vessels, Rentrop 2 or below was defined as poorly-developed collateral circulation group, including 29 vessels.TAG values in patients with various Rentrop grades were analyzed.Univariate and multivariate analysis were used to determine the predictors of collateral circulation. Results: TAG increased consistently in proportion to the angiographic extent of collateral flow (TAG was (-33.6±24.4), (-16.5±15.7) and (-12.8±15.8) HU/10 mm in patients with Rentrop grade 0 or 1, 2 and 3, respectively, P=0.007). Number of good collateral circulation vessels predicted by TAG≥15.6 HU/10 mm was 45(57.0%, 45/79), and 50 (63.3%, 50/79) by Rentrop grade (P=0.383). Prevalence of diabetes was significantly lower (20.8%(10/48) vs. 48.1%(13/27), P=0.01), while history of previous myocardial infarction (MI) was significantly higher (35.4%(17/48) vs. 11.1%(3/27), P=0.02) in patients with good collateral circulation than in patients with poor collateral circulation.The TAG of the good collateral circulation group was significantly higher than in poorly collateral circulation group ((-12.8±15.8) HU/10 mm vs. (-21.2±19.6) HU/10mm, P=0.041). Multiple logistic regression analysis revealed that history of MI (OR=0.196, 95%CI 0.041-0.936, P=0.041) and diabetes(OR=6.604, 95%CI 1.726-25.274, P=0.006) were independent predictors of coronary collateral circulation. Conclusions: TAG could be used to evaluate status of coronary collateral circulation.Presence of MI history and absence of diabetes history are the two independent predictors of well-developed coronary collateral circulation in CTO patients.

Abstract
Objective: To determine the relevance between the SOX10 mutation and Waardenburg syndrome (WS) accompanied with inner ear abnormality by analyzing the inner ear imaging results and molecular and genetic results of the WS patients with the SOX10 mutation. Methods: This study included 36 WS in patients during 2001 and 2015 in the department of otorhinolaryngology head and neck surgery, Chinese Peoples's Liberation Army General Hospital. The condition of the inner ear of each patient was assessed by analyzing HRCT scans of the temporal bone and MRI scans of the brain and internal auditory canal. Meanwhile, the possible pathogenic genes of WS, including SOX10, MITF, and PAX3, were also screened. Patients were divided into two groups according to SOX10 mutation.The Fisher accuracy test was used to determine statistical difference of inner ear deformation incidence between the two groups. Results: Among all 36 patients, 12 were found to have inner ear abnormality. Most abnormalities were posterior semicircular canal deformations, some accompanied with cochlear deformation and an enlarged vestibule. Among all patients, 9 patients were SOX10 heterozygous mutation carriers, among which six showed bilateral inner ear abnormality. Fisher accuracy test results suggested a significant correlation between the SOX10 mutation and inner ear abnormality in WS patients (P=0.036). Conclusion: This study found that WS patients with the SOX10 mutation are more likely to have deformed inner ears when compared to WS patients without the SOX10 mutation.

Abstract
Objective: Mesenteric panniculitis is an idiopathic, uncommon disease involving the adipose tissue of mesentery. The etiology, diagnosis and treatment are still unnoticed. We thus reported a case series to improve the understanding of this rare disorder. Methods: We retrospectively analyzed the clinical data of 12 patients with mesenteric panniculitis including manifestation, diagnosis, treatment and prognosis. Results: We found a male predominance (M∶F 3∶1) with the median age of 58 years old at diagnosis. The most common symptom was abdominal pain (9/12), followed by abdominal distension (3/12) and weight loss (3/12). Physical examination was unremarkable in the majority of patients (8/12). C reactive protein (9/12) and erythrocyte sedimentation rate (10/12) were normal in majority of patients. CT findings were of much diagnostic value. All patients had small intestinal mesentery involvement and multi-nodular appearance with increased fat density. Pseudo-capsule sign (8/12) and fat halo sign (6/12) were common. Pathological diagnosis was obtained in 4 cases showing fat tissue inflammation with local necrosis and fibrosis. Six cases all received prednisone, 2 with combined cyclophosphamide, 1 with azathioprine, 1 with tripterygium wilfordii. Short-term clinical response was achieved in all cases, but two patients relapsed. Conclusions: Mesenteric panniculitis occurs predominantly in middle-aged and elderly. Abdominal pain is the leading symptom. Inflammatory markers are often normal while computed tomography is the most important diagnostic tool. Surgery combined with cortical steroid and immunosuppressant agents is effective.

Abstract
Stem cell therapy faces many problems including poor survival rates and low viability. Enhancing the biological functions of stem cells improves efficacy of therapies. Estrogen, whose levels are elevated during pregnancy, affects the properties of bone marrow mesenchymal stem cells. Evidence suggests that adipose-derived stem cells (ADSCs), which are a type of adult mesenchymal stem cells, can be used in regenerative medicine. In fact, ADSCs from pregnant animals have been used in clinical therapies. However, the effect of the donor's reproductive status on proliferation of ADSCs is unknown. We investigated the effect of 17β-estradiol (E2) and progesterone (P) on the in vitro proliferation of ADSCs from laboratory rats. ADSCs were obtained from five different groups of 15 rats each - non-pregnant, pregnant, in perinatal period, non-pregnant and treated with E2, and non-pregnant and treated with P. Adhesion and viability of ADSCs were determined by MTT assay, and cell cycle was followed by flow cytometry. The proliferation rate of ADSCs from pregnant rats was significantly higher than those from the non-pregnant rats (P < 0.05); however, there was no statistically significant difference in proliferation rates during different phases of pregnancy (P > 0.05). Additionally, ADSCs from pregnant rats possess higher adhesion property in early stage (P1 passage) and higher proliferation rate than ADSCs from non-pregnant rats. Interestingly, ADSCs from non-pregnant rats that were treated with E2, but not those treated with P, showed higher proliferation rates than those from their untreated counterparts. These results suggest that the proliferative capacity and residence time in different cell cycle phases of ADSCs can be regulated by extrinsic factors such as estrogen concentration.

Objective: To systematically review the efficacy, side effects and case-fatality rate of levetiracetam (LEV) versus phenytoin (PHT) for seizure prophylaxis of brain injured patients. Methods: Randomized controlled trials of high quality about LEV versus PHT in seizure prophylaxis of brain injured patients from 2000 to 2016 were collected according to the key word PHT, LEV, brain injury in PubMed, Medline, Ovid, Springer, CNKI, Wanfang data and so on. Valid data were extracted to conduct meta-analysis by RevMan 5.3 software according to inclusion and exclusion criteria. Results: A total of 13 English articles were finally included with 2 529 patients in total.Meta-analysis showed that no significant differences were observed in LEV versus PHT at preventing the occurrence of seizures (RR=0.88, 95%CI: 0.61-1.27). No superiority of either drug at preventing early seizures (RR=0.74, 95%CI: 0.42-1.27). As to the occurrence of late seizures, the differences of the two drugs were not statistically significant (RR=0.71, 95%CI: 0.43-1.20). Number of patients with side effect was not statistically significantly different between the two groups (RR=0.73, 95%CI: 0.48-1.11). But significant difference was found between LEV and PHT in discontinuation because of side effect (RR=0.11, 95%CI: 0.06-0.23); no significant differences were noted in the case-fatality rate of patients received pretreatment between the two drugs (RR=1.57, 95%CI: 0.92-2.67). There were no significant differences between the two groups in the length of stay (WMD=-1.03, 95%CI: -4.97-2.91). Conclusions: LEV and PHT demonstrate equal efficacy in seizure prevention after brain injury. The differences are insignificant in the side effect, the case-fatality rate and the length of stay between LEV and PH treatment, but adverse drug reactions requiring change in therapy occur more in PHT. Phenytoin remains the first choice for seizure prevention after brain injury based on the existing evidence, while levetiracetam seems to be a favorable choice where there is risk of drug-drug interactions and drug toxicity. However, very few randomized controlled trials on this topic were found, and larger prospective trials are warranted.

Abstract
OBJECTIVE To measure the clivo-axial angle (CAA) and cervicomedullary angle (CMA) in upper cervical deformity patients who underwent computer-assisted posterior upper cervical reduction and fixation surgery, and analyze their correlation. METHODS In the study, 25 patients with symptomatic upper cervical deformity were chosen for measurement of preoperative and postoperative CMA and CAA using magnetic resonance imaging (MRI) and intraoperative C-arm. The angle between the clivus plane and the straight line parallel to that of the posterior margin of the C2 vertebral body was defined as CAA; moreover, the angle between the straight line parallel to the ventral side of the cervical spinal cord and the straight line parallel to that of the ventral side of the medulla oblongata was defined as CMA. Two experienced spinal surgeons performed the measurements. The CAA and CMA were measured three times, and the mean value was considered as the result. RESULTS Analyses of the CAA and CMA were performed with Wilcoxon rank test, which showed that there was consistency between the CAAs measured with MRI and intraoperative C-arm. The result showed that the postoperative CAA and CMA increased significantly compared with preoperation (P<0.001). Through Spearman rank correlation analysis, the preoperative CAA was positively correlative with the CMA (r=0.902, P<0.001), and so was the postoperative CAA (r=0.921, P<0.001). CONCLUSION Preoperative and postoperative CAA in upper cervical deformity patients is significantly correlative with preoperative and postoperative CMA. CAA can be measured during surgery using intraoperative CT or C-arm based three-dimension navigation, and may predict the patient's CMA, which cannot be measured during operation, but is essential for evaluating the decompression and reduction of the spinal cord.

Abstract
BACKGROUND Hemophilia A (HA) is an X-linked bleeding disorder caused by deleterious mutations in the coagulation factor VIII gene (F8). To date, F8 mutations have been documented predominantly in European subjects and in American subjects of European descent. Information on F8 variants in individuals of more diverse ethnic backgrounds is limited. OBJECTIVES To discover novel and rare F8 variants, and to characterize F8 variants in diverse population backgrounds. PATIENTS/METHODS We analyzed 2535 subjects, including 26 different ethnicities, whose data were available from the 1000 Genomes Project (1000G) phase 3 dataset, for F8 variants and their potential functional impact. RESULTS We identified 3030 single nucleotide variants, 31 short deletions and insertions (Indels) and a large, 497 kb, deletion. Among all variants, 86.4% were rare variants and 55.6% were novel. Eighteen variants previously associated with HA were found in our study. Most of these 'HA variants' were ethnic-specific with low allele frequency; however, one variant (p.M2257V) was present in 27% of African subjects. The p.E132D, p.T281A, p.A303V and p.D422H 'HA variants' were identified only in males. Twelve novel missense variants were predicted to be deleterious. The large deletion was discovered in eight female subjects without affecting F8 transcription and the transcription of genes on the X chromosome. CONCLUSION Characterizing F8 in the 1000G project highlighted the complexity of F8 variants and the importance of interrogating genetic variants on multiple ethnic backgrounds for associations with bleeding and thrombosis. The haplotype analysis and the orientation of duplicons that flank the large deletion suggested that the deletion was recurrent and originated by homologous recombination.

Abstract
We evaluated changes in BAX and BCL2 expression levels after spinal cord ischemia/reperfusion injury (SCII) and hypothermia during operations in rats. Eighty rats were divided into four groups: Group A (N = 20, 18°C); Group B (N = 20, 28°C); Group C (N = 20, room temperature); and Group D (N = 20, sham operation control). Spinal cord ischemia was induced for 90 min. Hypothermia was induced 15 min before, and maintained during ischemia, followed by heating to normothermia for 30 min after reperfusion. Motor function of the lower limbs was evaluated according to the Tarlov score at 72 and 168 h. For each rat, spinal cord samples were taken at 6, 24, 72 h, and 1 week to evaluate the histopathological changes, neuronal apoptosis, and BAX and BCL2 expression levels. Compared with normothermia, hypothermia significantly improved hind limb function; Group B achieved a higher score than Group A. Group D showed no neurologic deficiency, while the other groups showed various degrees. Group C exhibited greater neuronal apoptosis, higher BAX expression, but lower BCL2 expression than the other groups. Compared with Group A, BAX was expressed less and BCL2 more in Group B, and there was less apoptosis in Group B. Hypothermia preserves hind limb motor function and reduces neuronal death, thereby protecting rats from SCII. The spinal cord may be protected from SCII by inhibition of BAX and activation of BCL2. However, deep hypothermia may inhibit the expression of BCL2, resulting in a worse outcome than mild hypothermia.

Abstract
The incidence of asthma is more common in boys than in girls during the childhood, and more common in premenopausal female than age-matched males. Our previous study demonstrated a gender difference in histamine-mediated neuroexcitability in nodose ganglia neurons (NGNs), highlighting a possibility of histamine-mediated gender difference in asthma via visceral afferent function. In the present study, we aimed to explore the gender difference in expression profiles of histamine receptors (HRs) in nodose ganglia (NG) and individual identified NGNs to provide deeper insights into the mechanisms involved in sexual dimorphism of asthma. Western-blot and SYBR green RT-PCR showed that H2R and H3R were highly expressed in NG of females compared with males and downregulated in ovariectomized females. H1R was equally expressed in NG of both sexes and not altered by ovariectomy. Furthermore, this highly expressive H2R and H3R were distributed in both myelinated and unmyelinated NGNs isolated from adult female rats by immunofluorescence and single-cell RT-PCR. H3R widely distributed in all tested neuron subtypes and its expression did not show significant difference among neuron subtypes. H2R was widely and highly expressed in low-threshold and sex-specific subpopulation of myelinated Ah-types compared with myelinated A- and unmyelinated C-type NGNs. Unexpectedly, weak expression of H1R was detected in both myelinated and unmyelinated NGNs by immunofluorescence, which was further confirmed by single-cell RT-PCR. Our results suggest that the sexual dimorphism in the expression of H2R and H3R in vagal afferents very likely contributes, at least partially, to the gender difference in prevalence and severity of asthma.

Abstract
INTRODUCTION Increased estrogen production in placenta towards the end of gestation plays a pivotal role in the onset of human labor. Estrogen transforms myometrium from a quiescent to a contractile status. Glucocorticoids have been shown to induce estrogen production through the transcription factor specificity protein 1 (Sp1)-mediated induction of aromatase transcription upon elevation of cyclic adenosine mono-phosphate (cAMP) level in human placental syncytiotrophoblasts. However, it is unclear how glucocorticoids activate cAMP pathway thereby inducing aromatase expression in human placental syncytiotrophoblasts. MATERIAL AND METHODS We investigated this issue in cultured primary human placental syncytiotrophoblasts prepared from placentas collected at term without labor. RESULTS We demonstrated that cortisol (0.01-1 μM) dose-dependently increased corticotropin-releasing hormone (CRH) and human chorionic gonadotropin (hCG) α/β subunit expression and their production in the syncytiotrophoblasts. The induction of intracellular cAMP level, Sp1 expression, Sp1 enrichment at the aromatase promoter as well as aromatase expression by cortisol could be partially attenuated by either hCG antibody (1:100) or CRH receptor antagonist α-helical-CRH (1 μM), and further attenuated by combination of hCG antibody and α-helical-CRH. CONCLUSIONS Cortisol increases aromatase expression via induction of CRH and hCG production and subsequent elevation of cAMP level and enrichment of Sp1 at the aromatase promoter in human placental syncytiotrophoblasts. These findings may account for the parallel increases of cortisol and estrogen production prior to the onset of parturition.

Abstract
Antimony (Sb) distribution, solubility and mobility onto natural soils of China were studied in lysimeter and batch experiments as a function of physicochemical properties of the soil. An outdoor lysimeter experiment investigated the leaching and migration of Sb in the soils with Sb-polluted topsoil and unpolluted subsoil over a 5month period. Soil solutions were collected by suction cups installed at different depth of lysimeters, and leachates were regularly collected and analyzed for Sb concentrations. The majority of the added Sb was retained in the topsoil layers, but small portions were moved to the sub-layers. Sb concentrations in the soil solutions and leachates ranged from 0-755.5 (6.38±54 on average) μg l(-1) and 0-0.45 (smaller than the detection limit) μg l(-1) respectively, indicating the low solubility of Sb in the soils. Batch experiments were performed in order to determine the sorption capacity and the partition coefficient (Kd). Freundlich isotherm described properly the equilibrium experimental data and results show that the Kd values for Primosol, Isohumosol, Ferrosol equal to 22.5, 87.8, 704 L kg(-1), respectively. These results showed the strong capacity of the soils to retain Sb, and prevent it being leached down the profile. The mobilizable Sb was in the order: Primosol>Isohumosol>Ferrosol. Sb migration in the soils was mainly associated with the exchangeable, carbonate-bound, and metal-organic complex-bound fractions. Health risk assessment indicates that Sb leaching from Ferrosol will not harm to human health through groundwater under the test conditions, while it has certain health risks from the Isohumosol and Primosol.

Abstract
The plasmon resonance and electric field enhancement in a side-by-side tangent nanospheroid homodimer (TNSHD) have been investigated theoretically by using DDA and FDTD methods, respectively. The simulation results indicate that this side-by-side TNSHD has its novel optical properties. We find that the plasmon resonance with a distinct Fano lineshape can be achieved and the electric field intensity can be enhanced strongly. The tunability of the Fano resonance could provide important applications in biosensing. The obtained electric field enhancement might open a promising pathway for surface-enhanced Raman scattering (SERS) and light trapping in solar cells.

Abstract
CONCLUSIONS The diagnosis of occult otogenic cerebrospinal fluid (CSF) leakage is challenging and it can easily be misdiagnosed. Some characteristics of clinical presentation can supply important clues and confirmed diagnosis should be obtained according to these clues and suitable imaging studies before meningitis develops. Different surgical techniques should be adopted to treat the CSF leakage according to different leakage etiologies, and good results can be obtained. OBJECTIVE The aim of the study was to evaluate the diagnosis and surgical treatment of occult otogenic CSF leakage, including the characteristics of clinical presentation, imaging studies, and operation methods in order to decrease the rate of misdiagnosis and obtain a good curative effect. METHODS We performed a retrospective review of 11 cases of CSF leakage that were all misdiagnosed and accompanied by meningitis, operated in our department from 2007 to 2012 after a mean follow-up of 3 years. In this context, the characteristics of clinical presentation, imaging studies, and management of CSF leakage were studied. RESULTS The CSF leakage had arisen traumatically (n = 9) or congenitally (n = 2). The medical history and special clinical presentation such as repeated otorrhea or rhinorrhea, fever, headache, and unilateral deafness can supply important diagnostic clues. Imaging studies including high-resolution noncontrast CT (HRCT), CT cisternography, and magnetic resonance imaging (MRI) are very important diagnostic methods. The surgical repairs were performed via a transmastoid approach (n = 8), packing the vestibule (n = 1) or a translabyrithine approach (n = 2). Recurrent leakage did not occur.

Abstract
Genetic transformation is useful for basic research and applied biotechnology. However, genetic transformation of microalgae is usually quite difficult due to the technical limitations of existing methods. We cloned the promoter and terminator of the nitrate reductase gene from the microalga Phaeodactylum tricornutum and used them for optimization of a transformation system of the microalga Chlorella vulgaris. This species has been used for food production and is a promising candidate as a bioreactor for large-scale production of value-added proteins. A construct was made containing the CAT (chloramphenicol acetyltransferase) reporter gene driven by the nitrate reductase promoter. This construct was transferred into the C. vulgaris genome by electroporation. Expression of CAT in transgenic Chlorella conferred resistance to the antibiotic chloramphenicol and enabled growth in selective media. Overall efficiency for the transformation was estimated to be approximately 0.03%, which is relatively high compared with other available Chlorella transformation systems. Expression of CAT was induced in the presence of nitrate and inhibited in the presence of ammonium as a sole nitrogen source. This study presented an inducible recombinant gene expression system, also providing more gene regulation elements with potential for biotechnological applications.

Abstract
CONTEXT Overexposure of the fetus to glucocorticoids early in gestation is detrimental to fetal development. Glucocorticoid concentrations in the fetal circulation are kept low by 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2, encoded by HSD11B2) in the placental syncytiotrophoblasts. However, cytotrophoblasts, the progenitors of syncytiotrophoblasts, express low levels of 11β-HSD2. Here we studied the molecular mechanisms underlying 11β-HSD2 induction upon syncytialization. METHODS Freshly isolated human term placental cytotrophoblasts and in vitro differentiated syncytiotrophoblasts were examined to determine the methylation status of HSD11B2 promoter. The transcription factor responsible for 11β-HSD2 induction was identified by observing its expression upon syncytialization, the effect of its attenuation, and its binding to the HSD11B2 promoter. RESULTS 11β-HSD2 expression was markedly increased upon syncytialization in vitro. No methylation differences of HSD11B2 promoter were found between cytotrophoblasts and syncytiotrophoblasts. Expression of the transcription factor Sp1 was markedly induced during syncytialization and further increased by activation of the cAMP pathway, which correlated with 11β-HSD2 expression. Importantly, small interfering RNA-mediated knockdown of Sp1 expression or inhibition of Sp1 activity with mithramycin A markedly attenuated not only basal but also cAMP pathway-stimulated expression of 11β-HSD2 in the syncytiotrophoblasts. Stimulation of the cAMP pathway also increased the binding of Sp1 and RNA polymerase II to HSD11B promoter in syncytiotrophoblasts. Concomitantly, acetylation at histone H3K9 was increased whereas methylation at histone H3K9 was decreased. CONCLUSIONS 11β-HSD2 induction upon syncytialization is at least in part due to the increased expression of Sp1 upon activation of the cAMP pathway rather than the differential methylation of the HSD11B2 promoter.
