Abstract
Objective: To explore the value of anti-Müllerian hormone (AMH) and age in predicting outcomes of patients undergoing in vitro fertilization and embryo transfer treatment. Methods: In this retrospective study, 6 328 Chinese patients who underwent the first in vitro fertilization or intracytoplasmic sperm injection and embryo transfer treatment in Henan Provincial People's Hospital between July 2016 and July 2018 were analyzed. All the patients were categorized into two groups according to pregnancy or not. Baseline data and outcomes of two groups were compared. The regression analysis was conducted to identify the independent factors of clinical pregnancy rates. Furthermore, correlation analysis was performed between AMH and other factors. Results: (1) The total clinical pregnancy rate was 56.86% (3 547/6 238). Age, AMH, basal FSH, antral follicle number (AFC), starting dose of gonadotropin (Gn), total doses of Gn, duration of Gn, number of oocytes, transferable cleavage embryos and transferred embryos were significantly different (all P<0.01). (2) Correlation analysis showed that AMH had significant passive correlation with age, basal FSH, starting dose of Gn and total doses of Gn (all P<0.01), while showed significant positive correlation with AFC, body mass index, duration of Gn, number of oocytes and transferable cleavage embryos (all P<0.01). Of all the factors, AMH had the strongest correlation with AFC (P<0.01). (3) Multivariate logistic regression analysis suggested that age was the independent influencing factor of clinical pregnancy rate (OR=0.938, 95%CI: 0.824-0.952, P<0.01), while AMH not (OR=1.004, 95%CI: 0.984-1.024, P=0.687). In the subgroups according to age, the advanced group (age>35 years old) had lower clinical pregnancy rate and higher cancellation rate for no available embryos. Conclusions: AMH has no predictive value of clinical pregnancy outcomes for patients with in vitro fertilization and embryo transfer treatment, while age has certain predictive value of pregnancy outcomes. AMH level may have indictive value for the evaluation of ovarian reserve.

Abstract
This study examines the effects of environmental hazards, including tobacco, alcohol/alcohol flush response, areca nut, and Helicobacter pylori (H pylori) infection on upper digestive diseases. This is a multi-hospital-based endoscopy-survey cross-sectional study. Subjects were received upper endoscopies in outpatient clinics at four hospitals in Taiwan between 2008 and 2013. Biopsy-based methods or urea breath test were used confirm the status of H pylori infection. In total, 8135 subjects were analyzed. Higher cumulative amounts of alcohol consumption were at higher risk of Barrett's esophagus and esophageal squamous cell carcinoma (ESCC), higher cumulative amounts of tobacco consumption were at higher risk of peptic ulcer, and higher cumulative amounts of areca nut consumption were at higher risk of duodenitis. Alcohol flush response was significant risk for reflux esophagitis and Barrett's esophagus (adjusted odds ratio [aOR] = 1.18 and 1.32, 95% confidence interval [CI] = 1.07-1.31 and 1.06-1.65, respectively). H pylori infection was inversely associated with ESCC risk (aOR = 0.20, 95% CI = 0.10-0.40). In addition, H pylori infection was consistently and significantly risk factors for gastrointestinal diseases, including peptic ulcer, gastric adenocarcinoma, and duodenitis (aOR = 5.51, 1.84, and 2.10, 95% CI = 4.85-6.26, 1.03-3.26, and 1.71-2.56, respectively). Besides the cumulative risk of alcohol, tobacco, and areca nut for Barrett's esophagus, ESCC, and peptic ulcer, respectively, presence of facial flushing was the significant risk for reflux esophagitis and Barrett's esophagus. H pylori infection was positively associated with peptic ulcer, gastric adenocarcinoma, and duodenitis, but inversely associated with ESCC.

Abstract
Lupus nephritis (LN) is the leading cause of mortality in lupus patients. This study aimed to investigate the treatment outcome and renal histological risk factors of LN in a tertiary referral center. Between 2006 and 2017, a retrospective observational study enrolled 148 biopsy-proven LN patients. After propensity score matching, 75 cases were included for further analysis. The classification and scoring of LN were assessed according to the International Society of Nephrology/Renal Pathology Society. Treatment response was evaluated by daily urine protein and urinalysis at two years after commencing induction treatment and the development of end-stage renal disease (ESRD). In total, 50.7% patients achieved complete remission (CR) or partial remission (PR), while 49.3% patients were categorized as nonresponders. Therapeutic responses in terms of CR/PR rates were associated with Systemic Lupus Erythematosus Disease Activity Index scores (odds ratio (OR): 1.34, 95% confidence interval (CI): 1.12-1.60, p = 0.001). Moreover, higher baseline creatinine levels (hazard ratio (HR): 2.10, 95% CI: 1.29-3.40, p = 0.003), higher renal activity index (HR: 1.30, 95% CI: 1.07-1.58, p = 0.008) and chronicity index (HR: 1.40, 95% CI: 1.06-1.85, p = 0.017) predicted ESRD. Among pathological scores, cellular crescents (HR: 4.42, 95% CI: 1.01-19.38, p = 0.049) and fibrous crescents (HR: 5.93, 95% CI: 1.41-24.92, p = 0.015) were independent risk factors for ESRD. In conclusion, higher lupus activity was a good prognostic marker for renal remission. Renal histology was predictive of ESRD. Large-scale prospective studies are required to verify the efficacy of mycophenolate in combination with azathioprine or cyclosporine in LN patients.

Abstract
Objective: To determine whether asthma has a different metabolic glycerophospholipid profile in serum between women and men with asthma. Methods: Fifty-one outpatients with asthma (17 men, 34 women) were enrolled from Peking University Third Hospital from Jan 2015 to Dec 2015. Clinical data such as gender, age, body mass index, pulmonary function were recorded. Glycerophospholipid profile were measured in serum using liquid chromatography-mass spectrometry (LC-MS)-based metabolomics analysis. Projections to latent structures-discriminate analysis (PLS-DA) was used to compare the differences of glycerophospholipid level between men and women. Receiver Operating Characteristic (ROC) Curve was established from men and women. Results: Significantly different glycerophospholipid level were confirmed quantitatively between women and men. Levels of phosphatidylethanolamine (PE), phosphatidylcholine acetal phospholipid (PCP), lysophosphatidyl ethanolamine (LPE), alkyl phosphatidylethanolamine [PE(O)] were significantly higher in women relative to men [PE36: 2, PCP32: 1, LPE18: 0, and PE(O40: 7) was 0.050 (0.037, 0.079) vs 0.043 (0.000, 0.071), 0.057 (0.035, 0.727) vs 0.034 (0.000, 0.057), 0.233 (0.129, 0.390) vs 0.126 (0.075, 0.212), 0.007(0.000, 0.041) vs 0.000 (0.000, 0.000), respectively, all P<0.05). Levels of lysophosphatidylcholine (LPC), lysophosphatidylserine (LPS), and lysophosphatidylphosphatidylcholine [LPC(O)] were significantly lower in women compared to men [Levels of LPS22: 6, LPS20: 4, and LPS18: 1 were 0.000(0.000, 0.003) vs 0.009(0.000, 0.012), 0.015(0.010, 0.026) vs 0.047(0.022, 0.081), 0.008(0.003, 0.179) vs 0.020(0.008, 0.040), respectively, all P<0.05]. Area Under ROC Curve (AUC) of LPS (LPS20: 4) was 0.814. Conclusions: Glycerophospholipid levels in serum are significantly different between women and men asthmatic patients. LPS may contribute to gender based differences in asthmatics.

Abstract
The radiochromic film (RCF) is a high-dose, high-dynamic range dosimetry detection medium. A stack of RCFs can be used to detect both spatial and energetic distribution of laser driven ion beams with a large divergence angle and continuous energy spectrum. Two types of RCFs (HD-V2 and MD-V3, from Radiation Products Design, Inc.) have been calibrated using MeV energy protons and carbon ions produced by using a 2 × 6 MV tandem electrostatic accelerator. The proportional relationship is obtained between the optical density and the irradiation dose. For protons, the responses are consistent at all energies with a variation of about 15%. For carbon ions, the responses are energy related, which should be noted for heavy ion detection. Based on the calibration, the broad energy spectrum and charge distribution of laser accelerated proton beam with energy from 3 to 8 MeV and pC charge were detected and reconstructed at the Compact LAser Plasma Accelerator at Peking University.

Abstract
Objective: Inflammatory bowel disease (IBD) is generally considered as a major risk factor in the progression of colitis-associated colorectal cancer (CAC). Previous studies have indicated that the composition of gut microflora may be involved in CAC induction and progress. Bacteroides fragilis (BF) is a Gram-negative anaerobe belonging to colonic symbiotic bacteria of the host. This study was aimed to investigate the protective role of BF in a colorectal cancer (CRC) model induced by azoxymethane (AOM) and dextran sulfate sodium (DSS) in germ-free (GF) mice. Materials and methods: Total 22 GF mice were divided into two groups: GF and BF group. Half of the GF mice were colonized with BF for 28 days before CRC induction by AOM/DSS. Results: BF colonization increased animal survival (100%). Cecum weight and cecum/body weight ratio significantly decreased in BF/AOM/DSS group. Interestingly, there was a significant decrease in tumor number and tumor incidence in the BF/AOM/DSS group as compared to the GF/AOM/DSS group. The adenocarcinoma/adenoma incidence and histologic score were also decreased in the BF/AOM/DSS group. In addition, immunohistochemistry staining found decreased numbers of cell proliferation (PCNA) and inflammatory cell (granulocytes) infiltration in the colon mucosa of the BF group. The β-catenin staining in the BF/AOM/DSS group had fewer and weaker positive signal expressions. Taking together, the BF colonization significantly ameliorated AOM/DSS-induced CRC by suppressing the activity of cell proliferation-related molecules and reducing the number of inflammatory cells. Conclusions: Symbiotic BF may play a pivotal role in maintaining the gastrointestinal immunophysiologic balance and regulating anti-tumorigenesis responses.

Abstract
Objective: To assess the associations of indoor fine particulate matter (PM(2.5)) from outdoor and indoor sources with heart rate (HR) and heart rate variability (HRV) in patients with chronic obstructive pulmonary disease (COPD) of Beijing. Methods: A total of 40 male patients in a stable stage of COPD were recruited from a hospital in a panel study in Beijing with 5 consecutive days of measurement for each subject. General information and disease history of the participants from questionnaires were obtained prior to the study. HR and HRV were repeatedly examined using dynamic electrocardiograph. HRV included standard deviation of all NN intervals (SDNN), root mean square of successive differences between adjacent NN intervals (rMSSD), total power (TP) power in the low-frequency band (LF) and the high-frequency band (HF). Iron was used as tracer element to separate indoor-originated PM(2.5) and outdoor-originated PM(2.5). Mixed-effect models were applied to assess the associations of outdoor-originated PM(2.5) or indoor-originated PM(2.5) and health effects. Results: The P(50) (P(25), P(75)) values of daily indoor PM(2.5), indoor-originated PM(2.5) and outdoor-originated PM(2.5) were 50.9 (26.8, 122.7), 16.0 (1.9, 43.7) and 27.3 (13.5, 61.8) μg/m(3), respectively. The mean±SD of concentrations of real-time indoor PM(2.5), indoor-originated PM(2.5) and outdoor-originated PM(2).5 were (61.5±58.8), (25.3±39.1) and (36.2±42.7) μg/m(3), respectively. Compared with outdoor-originated PM(2.5), indoor-originated PM(2.5) had significant associations with HRV and HR. Each 10 μg/m(3) increase at 4 h indoor-originated PM(2.5) and outdoor-originated PM(2.5) moving average was associated with 3.4% (95%CI: -4.7%, -2.1%) and 0.6% (95%CI: -2.0%, -0.8%) reduction in TP (P<0.001). Each 10 μg/m(3) increase at 12 h indoor-originated PM(2.5) moving average was associated with 7.6% (95%CI: -10.1%, -5.1%), 4.7% (95%CI: -6.7%, -2.7%), 3.3% (95%CI: -4.2%,-2.4%) and 3.0% (95%CI: -4.5%, -1.5%) reduction in HF, LF, SDNN and rMSSD, respectively. Each 10 μg/m(3) increase at 12 h outdoor-originated PM(2.5) moving average was associated with 0.7% (95%CI: -2.7%, -1.4%), 0.2% (95%CI: -1.9%, 1.4%), 0.7% (95%CI: -1.4%, -0.1%) and 0.2% (95%CI: -1.3%, 0.9%) reduction in HF, LF, SDNN and rMSSD, respectively (P<0.001). Each 10 μg/m(3) increase at 8 h indoor-originated PM(2.5) and outdoor-originated PM(2.5) moving average was associated with 0.7% (95%CI: 0.4%, 1.0%) and 0.4% (95%CI: 0.2%, 0.6%) increase in HR. Conclusion: Exposure to indoor-originated PM(2.5) was more strongly associations with HRV indices and HR compared with outdoor-originated PM(2.5) in male COPD patients.

Abstract
Spinal cord injury (SCI) can cause loss of mobility in the limbs, and no drugs, surgical procedures, or rehabilitation strategies provide a complete cure. Exercise capacity is thought to be associated with the causes of many diseases. However, no studies to date have assessed whether congenital exercise ability is related to the recovery of spinal cord injury. High congenital exercise ability (HE) and low congenital exercise ability (LE) mice were artificially bred from the same founder ICR mice. The HE and LE groups still exhibited differences in exercise ability after 13 generations of breeding. Histological staining and immunohistochemistry staining indicated no significant differences between the HE and LE groups on recovery of the spinal cord. In contrast, after SCI, the HE group exhibited better mobility in gait analysis and longer endurance times in the exhaustive swimming test than the LE group. In addition, after SCI, the HE group also exhibited less atrophy than the LE group, and no inflammatory cells appeared. In conclusion, we found that high congenital exercise ability may reduce the rate of muscle atrophy. This result can be applied to sports science and rehabilitation science as a reference for preventive medicine research.

Abstract
Objective: To assess the association and intensity of baseline TC level with the incidence of lung cancer in men in China. Methods: Since May 2006, all the male workers, including the employees and the retirees in Kailuan Group were recruited in the Kailuan male dynamic cohort study. Information about demographics, medical history, anthropometry and TC level were collected at the baseline interview, as well as the information of newly-diagnosed lung cancer cases during the follow-up period. According to guidelines for blood lipids in Chinese adults and the distribution in the population, TC level was classified into five groups as followed: <160, 160-, 180-, 200- and ≥240 mg/dl, with the second quintile group (160- mg/dl) serving as the referent category. Cox proportional hazards regression model and restricted cubic spline (RCS) model were used to evaluate the association and the nonlinear association between baseline TC level and the risk of lung cancer in the men. Results: By December 31, 2014, for the 109 884 men, a follow up of 763 819.25 person-years was made with a median follow-up period of 7.88 years. During the follow up, 808 lung cancer cases were identified. After adjustment for age, education level, income level, smoking status, alcohol consumption level, history of dust exposure, FPG level and BMI, HR (95%CI) of lung cancer for men with lower TC level (<160 mg/dl) and higher TC level (≥240 mg/dl) were 1.34 (1.04- 1.72) and 1.45 (1.09-1.92), respectively, compared with men with normal TC level (160- mg/dl). The results didn't change significantly after exclusion of newly diagnosed cancer cases within 2 years of follow up and subjects with the history of hyperlipidemia. Conclusion: Our results showed that TC might be associated with higher risk of lung cancer. Men with lower TC level or higher TC level had higher risk for lung cancer. Keep moderate TC level might be one of the effective precaution for the prevention of lung cancer.

Abstract
OBJECTIVE To analyze the risk factors of early dental implant failure,treatment and prognosis. METHODS Cases of dental implants in the first clinical division from January 2000 to December 2016 were selected according to inclusion criteria. The differences of gender,age,smoking,location of implants, healing abutments and bone graft were compared between early failed implants and success implants. The general conditions of early failure patients, the early failure occurrence time, treatment and prognosis were recorded. Statistical methods were χ2 test and descriptive analysis, P<0.05 had statistical significance. Statistical analysis software was IBM SPSS Statistics 19.0. RESULTS There were 36 patients with 36 early failed implants and 4 381 patients with 6 564 success implants. The rate of early dental implant failure was 0.8% at individual level and 0.5% at implant level. There was no significant difference in gender between the failed implants and success implants (P=0.692). The failure rate of the patients ≥40 years old (1.0%) was higher significantly than that of the patients <40 years old(0.4%, P=0.033). The failure rate of smokers (1.3%) was higher significantly than that of non-smokers(0.3%,P<0.01). There was no significant difference of early failure among four implant locations, which were anterior maxilla, posterior maxilla, anterior mandibular and posterior mandibula (P=0.709). The early failure of implants with bone graft and healing abutments at the same time (1.1%) was significantly higher than that of the implants with bone and healing abutments separately (0.5%, P=0.039). Ten patents with early failed implants had general diseases, including 5 patients with diabetes, 3 with hypertension and 2 with coronary heart disease. All the patients with general diseases were controlled well. The median of early failure occurrence time was 30.5 after implant operations. 83.3% early failure implants was found by dentists at re-examinations. All of the early failure implants were removed when they were found failed. Twenty-six early failure implant sites were inserted with implants again, of which 23 implants were successful. CONCLUSION The early dental implant failure was possible to occur in one month after implants inserting. The possible risk factors were age≥40 years old, smoking and using bone graft and healing abutments at the same time. Most early dental implant failure was found by dentists at re-examinations. The implants should be removed when the early dental implant failure was found, which didn't influence the later implantation.

Abstract
Objective: To investigate the characteristics of impairment of the visual field (VF) and retinal nerve fiber layer (RNFL) and the differences of progression pattern of early, middle and late stages of primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG) , and to analyze the correspondence of structure and function. Methods: Cross-sectional study. POAG patients, NTG patients and healthy volunteers who were enrolled from February 2008 to May 2017 at Department of Ophthalmology, Eye & ENT Hospital of Fudan University, underwent basic ophthalmic examination, Humphrey central 24-2 threshold test and optical coherence tomography. Patients were divided into early, middle and late stages according to the mean defect (MD) index of the VF test. According to the RNFL distributional characteristics, the pattern deviation map and RNFL were divided into 6 sectors. The differences of each sector's MD and RNFL thickness in the healthy group and groups of patients at 3 stages were analyzed using the Kruskal-Wallis test, and the correlation of MD and RNFL thickness of each sector was analyzed using the Pearson coefficient. Results: In the POAG group, there were 84 cases (84 eyes) including 35 eyes of early stage, 20 eyes of middle stage and 29 eyes of late stage, with a male/female ratio of 43∶41, aged (45±15) years. In the NTG group, 69 cases (69 eyes) included 30 eyes of early stage, 20 eyes of middle stage and 19 eyes of late stage, with a male/female ratio of 33∶36, aged (49±13) years. The control group had 23 cases (23 eyes), with a male/female ratio of 16∶17 and an age of (44±10) years. There was no significant difference in male/female ratio, age or best corrected visual acuity among the three groups. (1) In the middle stage of POAG, the VF defects of inferior hemi-fields were more severe than the superior (t=21.62, P=0.000), which was opposite to the late stage of POAG (t=-3.28, P=0.003). In each stage of NTG, there was no significant difference between two hemi-fields. In the control group, the MD values(antilog) of VF in the superior peripheral arch (PEA), superior paracentral arch (PAA), inferior PEA and PAA, temporal and central regions were 0.87 (0.63-1.11)/L, 0.74 (0.61-0.83)/L, 0.72 (0.55-0.97)/L, 0.65 (0.51-0.87)/L, 0.69 (0.57-0.97)/L, and 0.82 (0.54-0.93)/L, respectively. The sectoral MD values in the VF sectors of POAG were significant compared with the control group (P<0.05): superior PAA for early stage [0.61 (0.18-0.92)/L, H=21.58], superior PEA and PAA for middle stage [0.61 (0.15-0.87)/L, 0.21 (0.00-0.78)/L, H=25.99, 34.91], superior PEA and PAA, inferior PEA and PAA for late stage [0.01 (0.00-1.13)/L, 0.00 (0.00-0.76)/L, 0.41 (0.00-1.07)/L, 0.21 (0.00-0.95)/L, H=46.27, 54.19, 25.64, 28.10]. With the aggravation of POAG, superior PAA had the largest reduction percentage of sectoral MD. The sectoral MD values in the VF sectors of NTG were significant compared with the control group (P<0.05): superior PAA for early stage [0.54 (0.19-0.80)/L, H=20.93], superior PAA for middle stage [0.60 (0.02-1.01)/L, H=22.13], superior PEA and PAA, inferior PEA and PAA for late stage [0.33 (0.00-0.90)/L, 0.05 (0.00-0.92)/L, 0.16 (0.01-0.87)/L, 0.64 (0.02-1.10)/L, H=37.66, 42.78, 35.15, 37.15]. With the aggravation of NTG, the largest reduction percentage of sectoral MD was found in superior PAA at the beginning but in inferior PAA at last. (2) The RNFL thickness of the control group in Region 1NI, 2TI, 3NS, 4TS, 5N, and 6T was 112.76 (63.54-150.99) μm, 134.89 (89.44-198.55) μm, 96.52 (57.32-158.79) μm, 120.96 (69.25-148.48) μm, 71.85 (65.03-95.47) μm, and 66.24 (55.44-90.97) μm, respectively. The sectoral thickness in the RNFL sectors of POAG were significant compared with the control group (P<0.05): 2TI for early stage [109.17 (43.77-173.86) μm, H=31.50], 1NI, 2TI and 4TS for middle stage [71.54 (49.92-94.98) μm, 62.92 (42.33-102.73) μm, 84.20 (45.98-120.13) μm, H=38.91, 49.89, 30.60], 1NI, 2TI, 3NS, 4TS, 5N and 6T for late stage [61.76 (39.32-97.99) μm, 59.59 (42.80-108.69) μm, 67.28 (42.56-117.96) μm, 65.16 (41.96-138.02) μm, 59.45 (21.04-78.48) μm, 53.74 (27.88-92.71) μm, H=52.76, 55.06, 35.76, 41.72, 41.32, 29.93]. With the aggravation of POAG, at the beginning 2TI had the largest reduction percentage of RNFL thickness but 4TS had it at last. The sectoral thickness in the RNFL sectors of NTG were significantly different from the control group (P<0.05): 2TI for early stage [78.97 (47.77-131.45) μm, H=28.86], 1NI, 2TI, 3NS and 4TS for middle stage [61.46 (49.69-97.38) μm, 74.51 (40.25-135.16) μm, 86.36 (42.70-105.06) μm, 83.60 (54.75-117.35) μm, H=38.76, 35.64, 22.47, 24.14], 1NI, 2TI, 3NS, 4TS and 6T for late stage [61.45 (49.09-92.64) μm, 54.35 (37.40-102.62) μm, 63.72 (28.68-105.55) μm, 61.00 (44.92-108.49) μm, 50.33 (35.62-82.09) μm, H=42.56, 51.50, 36.11, 47.44, 25.50]. With the aggravation of NTG, the sector with the largest reduction percentage of thickness changed from 2TI to NI and 4TS. (3) The VF superior PAA-RNFL 2TI had the highest Pearson correlation coefficient in POAG (r=0.630, P<0.001), while it was the inferior PAA-4TS in NTG (r=0.645, P<0.001). Conclusions: The impairment patterns of VF and RNFL in each stage of POAG and NTG are distinctly different from certain rules of aggravation. The sector with the strongest correlation of function-structure is the VF superior PAA-RNFL inferior temporal sector in POAG and inferior PAA-superior temporal sector in NTG.

Abstract
The electrical contact to two-dimensional (2D) semiconductor materials is decisive to the electronic performance of 2D semiconductor field-effect devices (FEDs). The presence of a Schottky barrier often leads to a large contact resistance, which seriously limits the channel conductance and carrier mobility measured in a two-terminal geometry. In contrast, Ohmic contact is desirable and can be achieved by the presence of a nonrectifying or tunneling barrier. Here, we demonstrate that a nonrectifying barrier can be realized by contacting indium (In), a low work function metal, with layered InSe because of a favorable band alignment at the In-InSe interface. The nonrectifying barrier is manifested by Ohmic contact behavior at T = 2 K and a low barrier height, ΦB = 50 meV. This Ohmic contact enables demonstration of an on-current as large as 410 μA/μm, which is among the highest values achieved in FEDs based on layered semiconductors. A high electron mobility of 3700 and 1000 cm2/V·s is achieved with the two-terminal In-InSe FEDs at T = 2 K and room temperature, respectively, which can be attributed to enhanced quality of both conduction channel and the contacts. The improvement in the contact quality is further proven by an X-ray photoelectron spectroscopy study, which suggests that a reduction effect occurs at the In-InSe interface. The demonstration of high-performance In-InSe FEDs indicates a viable interface engineering method for next-generation, 2D semiconductor-based electronics.

Abstract
Objective: To describe the clinical characteristics of pneumococcal infections and drug resistance of Streptococcus pneumoniae isolates from children's hospitals, which would provide reference for preventing and treating pneumococcal diseases. Methods: This was a prevalence survey. In this study, the age, specimen type, monthly distribution characteristics, and antimicrobial resistance of Streptococcus pneumoniae isolates from 9 children's hospitals in China were investigated between January 1, 2016 and December 31, 2016. The WHONET 5.6 software was used to analyze the antibiotic susceptibility of Streptococcus pneumoniae. The comparison of rates was performed by Chi-square test. Results: A total of 6 200 isolates of streptococcus pneumoniae were obtained, namely, 95.1% (5 876/6 177) from the respiratory tract specimens, 2.2% (136/6 177) from blood specimens and 0.4% (24/6 177) from cerebrospinal fluid specimens. The isolates were mainly from children older than 1 and younger than 5 years (54.7%, 3 381/6 185) . Most of strains (33.2%, 1 184/3 563) were isolated in November, December and January. Streptococcus pneumoniae isolates were completely sensitive to vancomycin (100.0%, 6 189/6 189) , linezolid (100.0%, 6 030/6 030) , moxifloxacin (100.0%, 3 064/3 064) , highly sensitive to levofloxacin (99.8%, 5 528/5 540), ertapenem (98.8%, 3 024/3 061) and lowly sensitive to erythromycin (1.7%, 102/6 016), clindamycin (3.7%, 116/3 136), and tetracycline (5%, 244/4 877), respectively. According to the parenteral susceptibility breakpoints for non-meningitis isolates, the sensitivity of Streptocococus pneumoniae to penicillin from children's hospital of Chongqing Medical University (49.3%, 892/1 809) was significantly lower than those of other hospitals (χ(2)=1 268.161, P<0.05) . Conclusions:Streptococcus pneumoniae is mainly isolated from respiratory tract, from children older than 1 and younger than 5 years and during November to January in tertiary children's hospital of China. The Streptococcus pneumoniae from children is highly sensitive to vancomycin, linezolid, moxifloxacin, levofloxacin. There are also significant differences in the sensitivity of penicillin for Streptococcus pneumoniae from different hospitals.

Abstract
This study aims to compare the effect of Philips' Brilliance 64-slice and 256-slice (multislice) computed tomography on effective doses when changing the operating parameters for simulated examinations of patients' spine tumors, including changes in pitch, tube voltage (kV), and effective tube current-time product (mA s). This study considers the possibility of using other probable operating conditions to reduce patients' effective doses. The absorbed doses to organs and skin are measured by taking data from thermoluminescent dosimeters (GR-200 and GR-200F) in relevant positions on the anthropomorphic Rando phantom. We also used an American College of Radiology computed tomography accreditation phantom to experiment with image spatial resolution under various scan conditions in order to achieve results over 5 line pairs per cm, the analytical capability required to meet diagnostic needs. The results show that, in general, when we change the pitch, effective tube current-time product, and tube voltage, the effective doses from 256-slice computed tomography exceed those from 64-slice computed tomography.

Abstract
We report on the measurement of the ^{7}Be(n,p)^{7}Li cross section from thermal to approximately 325 keV neutron energy, performed in the high-flux experimental area (EAR2) of the n_TOF facility at CERN. This reaction plays a key role in the lithium yield of the big bang nucleosynthesis (BBN) for standard cosmology. The only two previous time-of-flight measurements performed on this reaction did not cover the energy window of interest for BBN, and they showed a large discrepancy between each other. The measurement was performed with a Si telescope and a high-purity sample produced by implantation of a ^{7}Be ion beam at the ISOLDE facility at CERN. While a significantly higher cross section is found at low energy, relative to current evaluations, in the region of BBN interest, the present results are consistent with the values inferred from the time-reversal ^{7}Li(p,n)^{7}Be reaction, thus yielding only a relatively minor improvement on the so-called cosmological lithium problem. The relevance of these results on the near-threshold neutron production in the p+^{7}Li reaction is also discussed.

Abstract
Objective: To investigate the association between alcohol consumption and lung cancer risk in Chinese males. Methods: Information on alcohol consumption and outcomes were collected on a biennial basis among males in Kailuan Cohort (2006-2015). In addition, electronic databases of hospitals affiliated to Kailuan Community, Insurance Systems of Kailuan Community and Tangshan were also used for supplementary information retrieval. Cox proportional hazards regression models were used to evaluate the hazard ratio (HR) and 95%CI of baseline frequency and type of alcohol consumption associated with lung cancer risk in males. Non-drinkers were used as control group. Results: A total of 101 751 males were included and 913 new lung cancer cases were identified in the Kailuan male cohort study, with a total follow-up time of 808 146.56 person-years and a median follow-up time of 8.88 years by 31 December 2015. After adjusting for potential confounding factors, the HR of former drinkers, occasional drinkers (<1/day) and drinkers (≥1/day) were 1.30 (95%CI: 0.90-1.88), 0.80 (95%CI: 0.64-1.01) and 1.04 (95%CI: 0.85-1.27), respectively, compared with non-drinkers. In addition, drinking beer/red wine (HR=0.91, 95%CI: 0.69-1.20) and white wine (HR=0.99, 95%CI: 0.83-1.19) showed no significant association with lung cancer. The results were similar when stratified analysis were conducted. Conclusion: Our study results don't support the hypothesis that alcohol consumption is significantly associated with the risk of lung cancer in males.

Abstract
Objective: To understand the epidemiologic characteristics and spatial-temporal distribution of hepatitis E in Shanghai between 2006 and 2016. Methods: The reported incidence of hepatitis E and health facilities' information between 2006 and 2016 were collected from the China Information System for Disease Control and Prevention. The geographic information were from Shanghai Surveying and Mapping Institute. The map scale was 1∶750 000. Global and local autocorrelation, and spatial-temporal detection methods were applied to determine the spatial-temporal characteristics of hepatitis E. Software ArcGIS 10.1 was used to analyze global and local spatial auto correlation of hepatitis E spatial clusters. Software SaTScan 9.4.4 was used to conduct scan for exploring the areas of hepatitis E temporal spatial clusters. Results: A total of 6 048 cases of hepatitis E were reported in Shanghai during 2006-2016. The average incidence was 2.14/100 000. Spatial auto correlation analysis indicated that there was significant spatial positive correlations and spatial-temporal clustering of hepatitis E in Shanghai, and the "high-high cluster" was mainly located in the downtown of the city. Conclusion: Understanding the spatial-temporal clustering areas of hepatitis E cases in Shanghai from 2006 to 2016 is important to the reasonable allocation of public health resources and effective prevention and control of hepatitis E.

Abstract
Objective: To investigate the efficacy and drug related adverse reactions of sorafenib and sunitinib as first-line tyrosine-kinase inhibitors (TKIs) for patients with metastatic renal cell carcinoma (mRCC) and analyze the clinical prognostic factor for survival. Methods: The data of 271 patients with metastatic renal cell carcinoma who had complete clinicopathological data were retrospectively analyzed, including 174 cases in sorafenib group and 97 cases in sunitinib group, to access patients' overall survival (OS) and progression-free survival (PFS). Prognostic values of all characteristics were determined by using univariate and multivariate Cox regression models. Results: The objective response rates (ORR) of the sorafenib and sunitinib groups were 14.9% and 19.6%, respectively, and the disease control rates (DCR) were 85.1% and 88.6%, respectively. No significant difference was found between the sorafenib and sunitinib group in ORR (P=0.325) or DCR (P=0.408). The most common grade 3 to 4 adverse events in the sorafenib group were hand-foot syndrome (6.7%), diarrhea (2.3%), and rash (2.3%). The most common grade 3 to 4 adverse events in the sunitinib group were neutropenia (6.2%), hand-foot syndrome (6.2%), and thrombocytopenia (4.6%). During the follow-up, 97 cases death occurred and 81 cases disease progression occurred in sorafenib group. The median PFS was 12 months (95% CI: 9-15 months), and the median OS was 25 months (95% CI: 21-29 months) in sorafenib group. While 74 cases death occurred and 40 cases disease progression occurred in sunitinib group, the median PFS was 12 months (95% CI: 10-12 months) and the median OS was 23 months (95% CI: 20-32 months) in sunitinib group. No significant difference was found between the sorafenib and the sunitinib group in PFS (P=0.771) or OS (P=0.548). Multivariate analysis showed Fuhrman grades (HR=1.358, 95%CI: 1.004-1.835), number of metastatic sites (HR=1.550, 95%CI: 1.143-2.101) and MSKCC risk grade (Intermediate risk group: HR=1.621, 95%CI: 1.117-2.232; Poor risk group: HR=2.890, 95%CI: 1.942-4.298) were independent prognostic factors for PFS. Fuhrman grades (HR=2.135, 95%CI: 1.533-2.974), number of metastatic sites (HR=1.774, 95%CI: 1.279-2.461) and MSKCC risk grade (Intermediate risk group: HR=1.415, 95%CI: 1.002-1.998; Poor risk group: HR=3.161, 95%CI: 2.065-4.838) were independent prognostic factors for OS. Conclusions: The results of this study indicate that sorafenib and sunitinib are both effective as the first-line TKIs for mRCC patients and sorafenib has comparable efficacy to sunitinib. But they have differences in the incidence of adverse effects. Fuhrman grades, number of metastatic sites and MSKCC risk grade are independent prognostic factors for mRCC patients.
