Abstract
Objective: To investigate the effect of esmolol in septic shock patients with tachycardia. Methods: A prospective randomized controlled trial was conducted. Screening septic shock patients that admitted to Department of General Intensive Care Unit of the First Affiliated Hospital of Zhengzhou University from June 2016 to August 2017. After 24 h resuscitation therapy, 100 cases of septic shock patients with tachycardia (heart rate>100 bpm) were divided into esmolol group (n=50) and control group (n=50) with random number table. Patients in esmolol group accepted standard treatment plus esmolol injection with an initial dose of 25 mg/h. Heart rate target is 80 to 100 bpm. Patients in esmolol group continued to use esmolol for 7 days or to the day the patient left the ICU when the heart rate didn't achieve the target. Patients in control group were given standard treatment. Primary outcome was 28 d mortality. Secondary outcomes included heart rate, norepinephrine dosages, lactate level, inflammatory markers in per day during the trial; acute physiology and chronic health evaluation (APACHE Ⅱ) and sequential organ failure assessment (SOFA) on day 1, 3, 5, 7; length of hospital stay, length of mechanical ventilation, medication time of vasoactive agent. The data were compared with t test or rank sum test between the two groups. Results: The 28 d mortality of esmolol group and control group was 62%, 68%, respectively(χ(2)=0.529, P=0.529). Logistic regression analysis showed that primary heart rate (increase of 10 bpm, OR=1.568, 95%CI: 1.039-1.238, P=0.027), primary APACHEⅡ (OR=1.134, 95%CI: 1.026-1.239, P=0.005), integral heart rate (per 10 bpm, OR=2.207, 95%CI: 1.400-3.479, P=0.001) were independent risk factors for 28 d mortality. Compared with control group, the esmolol group had a lower heart rate on day 1-7; but over all, there was no statistically significant difference in heart rate between the two groups (P>0.05). There was no significant difference in total does of norepinephrine, lactate level, inflammatory markers, APACHE Ⅱ, SOFA, length of hospital stay between the two groups (all P>0.05). Conclusion: Tachycardia significantly increases the risk of death in patients with septic shock, esmolol may decrease the mortality by controlling heart rate.

Abstract
BACKGROUND Methotrexate (MTX) is an efficacious treatment for psoriasis; however, its widespread application is limited by its unpredictable efficacy. OBJECTIVES To investigate the association of clinical factors and variants of psoriasis susceptibility genes with clinical responses to MTX in a prospective cohort. METHODS A total of 221 patients with psoriasis were recruited. Patients who achieved Psoriasis Area and Severity Index (PASI) improvement ≥ 75% at week 12 were defined as responders, whereas those with PASI improvement < 50% were defined as nonresponders. In 90 screening patients, genetic variants for 18 single-nucleotide polymorphisms in 14 susceptibility genes, and HLA-Cw6 status were initially compared for responders and nonresponders. Statistically significant associations in genetic variants were verified in all 221 patients. RESULTS Overall, 49% and 45% of patients achieved PASI 75 improvement during screening and verification stages, respectively. Concomitant arthritis with psoriasis and high body mass index (BMI) negatively affect the efficacy of MTX. TT genotype of rs10036748 in TNIP1 was significantly associated with PASI 75 response at week 12 (54% and 37%, P < 0·05). A significantly higher PASI 90 response was observed in patients with TT genotype of rs10036748 (27% vs. 12%, P < 0·01) and TC/TT genotype of rs4112788 in LCE3D (25% vs. 13%, P < 0·05) at week 12 compared with those who had other genotypes. After adjustment for all confounding factors, only BMI (P < 0·05), arthritis (P < 0·05) and genotype of rs10036748 (P < 0·05) were significantly associated with clinical responses to MTX. CONCLUSIONS Patients with psoriasis with TT genotype of rs10036748 in TNIP1, with lower BMI, without arthritis will achieve a better response to MTX.

Abstract
Objective: To analyze the influencing factors on condom use among 35-years-or-older female sex workers (OFSWs) in Qingdao by using the three-level logistic model. Methods: From March to June 2014, OFSWs were recruited in Qingdao, using respondent-driven sampling. Related information on OFSWs and their recent five sexual partners (not including husband) were obtained by conducting a questionnaire survey on OFSWs. A Three-level logistic regression model was conducted to analyze the influencing factors of condom use between OFSWs and their sexual partners. Results: A total of 420 OFSWs participated the survey as well as information on 2 100 sexual partners. Results from the empty model showed that the use of condoms among OFSWs having an aggregation that related to the levels of working sites and their own behaviors. Results from the three-levels of logistic model analysis showed that, OFSWs that having had junior middle school education (OR=1.450, 95%CI: 1.054-1.994)/high school education or above (OR=2.264, 95%CI: 1.215-4.222), knowing the function of condom use (OR=2.004, 95%CI: 1.273-3.154) would have higher rates of condom use. OFSWs with higher score of attitude on condom use (OR=0.796, 95%CI: 0.745-0.849), having had syphilis infections in the past (OR=0.657, 95%CI: 0.478-0.902) would have lower rate of condom use. For the sexual partners, the rate of condom use among OFSWs' regular partners were higher than that of OFSWs' boyfriends (OR=15.291, 95%CI: 8.441-27.700; OR=29.032, 95%CI: 15.413-54.682). Conclusion: Condom use of OFSWs was affected by behaviors of both OFSWs themselves and their sexual partners. Prevention and control programs should focus on OFSWs and their sexual partners at the same time. The key intervention contents should include target populations as: OFSWs with low level of education, having had infections of syphilis, those who do not use condoms with their trusted partners.

Abstract
This work reports the in vivo uptake and translocation of PNPs in the one-year grown terrestrial plant, Murraya exotica ( M. exotica), as investigated by two-photon excitation and time-resolved (TPE-TR) optical imaging with a large field of view (FOV, 32 × 32 mm2) in a noninvasive and real-time manner. The PNPs (⟨ Rh⟩ = 12 ± 4.5 nm) synthesized from poly(styrene- co-maleic anhydride) (SMA) were Eu-luminescence labeled (λL ≈ 617 nm). On exposing the roots of living M. exotica plants to the colloidal suspension of SMA PNPs at different concentrations, the spatiotemporal evolution of SMA PNPs along plant stems (60 mm in length) were monitored by TPE-TR imaging, which rendered rich information on the uptake and translocation of PNPs without any interference from the autofluorescence of the plant tissues. The TPE-TR imaging combined with the high-resolution anatomy revealed an intercell-wall route in the lignified epidermis of M. exotica plants for SMA PNP uptake and translocation, as well as the similar accumulation kinetics at different positions along the plant stems. We modeled the accumulation kinetics with Gaussian distribution to account for the trapping probability of a SMA PNP by the lignified cell walls, allowing the statistical parameters, the average trapping time ( tm) and its variance (σ), to be derived for the quantification of the PNP accumulation in individual plants. The TPE-TR imaging and the analysis protocols established herein will be helpful in exploring the mechanism of plant-PNP interaction under physiological condition.

Abstract
Objective: To study the shift of oVEMP frequency tuning of unilateral Meniere's disease, by analyzing oVEMP of air-conducted tone bursts in various frequencies. Methods: From May 2016 to October 2017, 33 patients with unilateral Meniere's from Aerospace Center Hospital were tested for oVEMP in 500 Hz and 1 000 Hz air-conducted tone bursts respectively, and 20 healthy subjects(40 ears), matched for age and sex, were used as healthy control. The amplitudes of the N1-P1 wave and the frequency amplitude ratios of 500/1 000 Hz in affected ears, unaffected ears and normal ears were compared; and receiver operating characteristic curve was analyzed for frequency amplitude ratios of 500/1 000 Hz. Results: By the 500 Hz tone-burst stimulus, the provocation rates of the oVEMP were 84.9%(28/33), 93.9%(31/33) and 97.5%(39/40) in affected ears, contralateral ears and the ears of normal controls, respectively. By the stimulus of 1 000 Hz tone-burst, the provocation rates of the oVEMP were 81.8%(27/33), 87.9%(29/33) and 82.5% (33/40) in affected ears, contralateral ears and normal control ears, respectively. Amplitudes of N1-P1 waveforms in 500 Hz air-conducted tone bursts in affected ears were under normal control ears and contralateral ears. There was significant difference between affected ears and healthy control ears (P<0.05). Amplitudes of N1-P1 waveforms in contralateral ears were also significantly smaller than those in normal control ears (P<0.05). There were no significant differences in amplitudes of N1-P1 waveforms between affected ears, contralateral ears and normal control ears in 1 000 Hz tone bursts stimulus(P>0.05). Frequency amplitude ratios of 500/1 000 Hz in affected ears were significantly under contralateral and normal control ears (P<0.05). According to ROC, the frequency amplitude ratio critical value of frequency tuning was set as 1.17, the positive rate of frequency tuning shift in affected ears was 54.5%(18/33) and significantly higher than in contralateral ears(18.2%, 6/33, χ(2)=9.429, P=0.002) and normal control ears (7.5%, 3/40, χ(2)=19.530, P=0.000). In contrast, there was no significant difference in the incidence of frequency tuning shift between contralateral ears and normal ears(χ(2)=1.909, P=0.167). Conclusions: Frequency tuning oVEMP with Meniere's disease will be changed.Frequency tuning of oVEMP with Meniere's disease shifts from low frequency region to high frequency region in comparison with healthy people. Frequency amplitude ratio is helpful for diagnosis of Meniere's disease.

Abstract
Objective: To examine the risk factors for road traffic injury in agricultural vehicle drivers. Methods: A total of 103 drivers (who had suffered agricultural vehicle road traffic injury within the past year based on the road traffic injury registrar from the Traffic Management Bureau) who were involved in the annual agricultural vehicle inspection from December 2014 to January 2015 were randomly sampled from the Yixing Agricultural Vehicle Station as the case group for this study. Based on a 1∶2 assignment ratio and matched for sex, age, and education, a total of 206 drivers who had not suffered any agricultural vehicle road traffic injury within the past year were selected as the control group. The general information, vehicle information, driving information, driving behavior, and accident details of the agricultural vehicle drivers were analyzed. Results: The incidence rate of road traffic injury was 7.24% given the 103 agricultural vehicle drivers who had suffered agricultural vehicle road traffic injury in the past year. Univariate logistic regression analysis showed that drinking, debt, pressure, history of car accident, history of drunk driving, smoking and phone use during driving, fatigue driving, and driving with illness were the risk factors for road traffic injury in agricultural vehicle drivers (OR=2.332, 2.429, 19.778, 5.589, 8.517, 2.125, 3.203, 10.249 and 5.639, respectively) . Multivariate logistic regression analysis also demonstrated that pressure, history of car accident, history of drunk driving, fatigue driving, and driving with illness were the risk factors for road traffic injury in agricultural vehicle drivers (OR=12.139, 11.184, 6.729, 5.939, and 6.544, respectively) . Conclusion: Pressure, history of car accident, history of drunk driving, fatigue driving, and driving with illness are the major risk factors for road traffic injury in agricultural vehicle drivers.

Abstract
Objective: To explore the clinical and genetic characteristics of infantile nephrotic syndrome caused by COQ2 variants. Methods: The clinical and genetic data of a patient with nephrotic syndrome caused by COQ2 variants diagnosed at pediatric department of Peking University First Hospital from February 2018 to March 2018 were retrospectively analyzed. Related literature retrieved from PubMed, CNKI and Wanfang databases were searched to date (up to July 2018) with "COQ2 gene" or "primary coenzyme Q10 deficiency" and "nephrotic syndrome" or "nephropathy" as key words. Results: A 14-month-old male, presented to local hospital at 11 months of age with edema and severe proteinuria, without hematuria, hypertension or renal dysfunction. He did not have infection or seizure in the course of the disease. He had no response to a more than four-week full-dose prednisone treatment. He had normal birth, mild motor development retardation and moderate language retardation. He was born to non-consanguineous healthy parents. He had two unaffected older sisters and one older sister died of "nephropathy" at one year of age. Genetic testing identified compound heterozygous variants in COQ2 gene: c.518G>A and c.973A>G, both could be predicted by in silico tools to be deleterious in protein function. These variants are not single nucleotide polymorphism and rare in normal populations. Both variants have previously been reported as pathogenic. These missense mutations were inherited from parents in autosomal recessive manner tested by Sanger sequencing. The patient was supplemented with high-dose of coenzyme Q10, at 30 mg/(kg·day) and glucocorticoid was withdrawn. Within three weeks of high dose coenzyme Q10 treatment, the edema disappeared. After seven weeks of high dose coenzyme Q10 treatment, the patient had decreased proteinuria and improved serum albumin levels. The urine protein to creatinine ratio decreased from 22.87 mg/mg to 1.98 mg/mg; Serum albumin increased from 14.2 g/L to 39.9 g/L, with normal kidney function and improved motor development. Primary CoQ10 deficiency is reported to be a rare autosomal recessive mitochondrial disorder with heterogeneous renal, neurologic, and muscular manifestations. To date, COQ2 variants have been reported in 14 children with glomerular involvement. Their age at onset ranged from neonatal period to 10-year-old (8 patients within the first year of life). Steroid resistant nephrotic syndrome (SRNS) is the most common phenotype. Some of these children also had progressing encephalopathy and myopathy, and seizures. Patients with COQ2 variants might show clinical improvement with early high-dose oral CoQ10 supplementation. Literature review revealed two Chinese articles, mainly about adults with neurologic symptoms. SRNS was previously not reported in Chinese pediatric patients. Conclusions: It is necessary to carry out genetic testing for infant with SRNS. The coexistence of some degree of encephalomyopathy, such as development retardation, should raise suspicion of a mitochondrial defect caused by COQ2 variants. Timely diagnostic genetic testing and early high dose of coenzyme Q10 supplement could significantly improve their prognosis.

Abstract
Objective: To compare the safety of continued warfarin therapy and bridging anticoagulation therapy during hospital stay in patients undergoing percutaneous coronary intervention (PCI). Methods: We retrospectively analyzed patients on warfarin therapy referred for PCI in Beijing Anzhen Hospital from January 2008 to December 2016. The patients were divided into continued warfarin therapy (n=195) or bridging anticoagulation therapy (n=311) groups. After Propensity Score Matching, data from matched patients (n=123 in each group) were analyzed. Bleeding complications and major adverse cardiac events including death, myocardial infarction, target vessel revascularization, and stent thrombosis were assessed. Results: There were no significant difference in the rate of death (2.4%(3/123) vs. 1.6%(2/123),P=0.54), acute myocardial infarction (4.1%(5/123) vs. 4.9%(6/123), P=0.78),re-revascularization (0.8%(1/123) vs. 1.6%(2/123),P=0.16), stent thrombosis (1.6%(2/123) vs. 1.6%(2/123),P=1.00) and stroke between the two groups. Prevalence of minor bleeding complications was significantly higher in the bridging therapy group (15.4%(19/123) vs. 9.8%(12/123),P=0.01). Rate of access-site complications (hematoma:4.1%(5/123) vs. 2.4%(3/123),P=0.20; pseudoaneurysm:2.4%(3/123) vs. 2.4%(3/123),P=1.00; arteriovenous fistula:0.8%(1/123) vs. 1.6%(2/123),P=0.09; and retroperitoneal hematoma:0(0/123) vs. 0.8%(1/123),P=0.23) were similar between the two groups. Conclusion: For patients receiving chronic warfarin therapy, the uninterrupted oral anticoagulant treatment is as safe as bridging therapy in PCI patients.

Abstract
Objective: To analyze the clinical and immunological characteristics of acute severe bilateral optic neuritis, and to explore the predictive factors of vision outcome and relapse so as to save visual function and avoid or alleviate vision disability. Methods: Forty-eight inpatients confirmed with acute severe bilateral optic neuritis from January 2013 to June 2015 were included and followed up. The clinical features, immunological findings, optic nerve imaging, visual function outcome and predictors of relapse were statistically analyzed. Results: Acute severe bilateral optic neuritis accounted for 7.3% of the total number of optic neuritis in the same period. There were 35 cases (72.9%) with monophasic course, and 13 cases (27.1%) with recurrence or other central nervous system involvement during the follow-up period; 11 (22.9%) in 48 patients with positive AQP4-IgG; AQP4-IgG-positive patients had a higher recurrence rate (P<0.001) and poorer visual function prognosis (P=0.034) than antibody-negative patients; the baseline visual acuity (P=0.004), early treatment response (P=0.012) and number of involved optic nerve segments (P=0.016) were associated with end point visual function. Positive AQP4-IgG(OR 13.486, 95% CI 1.971-16.263)and combining with other autoimmune antibodies (OR 5.591, 95% CI 1.502-15.621)were independently associated with relapse. Conclusions: Acute severe bilateral optic neuritis is not unusual and may cause blindness or visual disability. The positive rate of AQP4-IgG and the recurrence rate of the disease are low in our study. The necessity for long-term immunotherapy requires individual consideration. The baseline visual acuity, involved segment number of optic nerve and response to early treatment are associated with prognosis of visual function. Patients with AQP4-IgG positive and other autoimmune antibodies are easy to relapse. Whether the antibody-negative bilateral optic neuritis is a heterogeneous disease and the relationship with classic NMO or NMOSD deserve further research.

Abstract
Objective: to investigate the clinical characteristics and disease activity in ankylosing spondylitis (AS) patients with hyperuricemia. Method: Laboratory tests, magnetic resonance imaging, disease activity and functional index of AS patients from Fudan University Zhongshan Hospital were collected. T test, square test were applied to investigate the difference between AS patients with hyperuricemia and AS patients with normal serum uric acid in clinical characteristics and disease activity in AS patients. Result: Among all the AS patients, 23.4% (22/94) patients accompanied with hyperuricemia. AS patients accompanied with hyperuricemia showed significant younger age (28.9±7.9 vs 35.8±11.1, P=0.002); higher serum alanine aminotransferase (33.6±23.6 vs 19.8±12.4, P=0.014), aspartate aminotransferase (23.8±8.7 vs 18.6±9.6, P=0.025) and creatinine (78.4±12.5 vs 69.8±13.3, P=0.009), lower Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) (11.2±8.8 vs 17.9±12.0, P=0.027) and Bath Ankylosing Spondylitis Functional Index (BASFI) (0.7±0.9 vs 1.8±2.2, P=0.002) compared with AS patients whose serum uric acid level is normal. Conclusion: AS Patients with younger age, impaired hepatic and renal funtion and lower scores in BASDAI and BASFI tend to accompany with hyperuricemia.

Abstract
Objective: To retrospectively review 4 cases diagnosed with pediatric acute respiratory distress syndrome (ARDS) who were transported with veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) from April 2016 to March 2017. Methods: Four patients were transported to Bayi Children's Hospital Afflicted to the PLA Army General Hospital, with V-V ECMO. Their vital signs, blood-gas analysis and chest X-ray before and after transportation were compared. The length of ECMO, pediatric intensive care unit (PICU) stay and hospitalization, and the prognosis were analyzed. Results: All the four cases were transported to our hospital successfully from distances between 1 000 km to 1 210 km. The 4 cases were 4 to 6 years old with the body weight of 19 to 35 kg, of whom 3 were boys and 1 was girl. The catheters were inserted in the right jugular vein and femoral vein. The vital signs and blood-gas analysis after transportation did not change significantly compared to baseline. The length of ECMO for the four patients were 48, 754, 157 and 438 hours. They stayed in the PICU for 10, 32, 14 and 19 days, respectively. At last, 2 of them were successfully discharged from hospital without any complications; however, the other 2 died of multiple organ failure. Conclusion: Transporting ARDS patients with a satisfactory cardiac function under VV-ECMO by an experienced ECMO team is safe.

Abstract
Objective: To evaluate the impact of cardiovascular risk factors on index of microvascular resistance (IMR) and coronary flow reserve (CFR) and to explore the characteristics of IMR and CFR and the relationship between IMR and angiographic features in patients with intermediate coronary stenosis and chest pain. Methods: Fractional flow reserve (FFR), CFR, and IMR were measured in patients who underwent invasive coronary angiography with 40%-70% stenosis by visual assessment. All patients with FFR>0.75 were enrolled and grouped with the cut-off points of IMR≥25 and CFR≤2.0. Patients with IMR≥25 were group H, including two sub-groups (high IMR-low CFR, group H1 and high IMR-high CFR, group H2), while those with IMR<25 were group N. The thrombolysis in myocardial infarction (TIMI) frame were counted. Results: A total of 34 patients with FFR>0.75 were enrolled with 61.8%(21 cases) of males and 38.2% (13 cases) of females. The mean age was (57.3±8.1) years old. High IMR accounted for 47.1% of all cases. There was significant difference between group H and N in TIMI frame (33.0 vs. 20.8, P=0.031). There were significant differences between group H1 and H2 in homocysteine (17.8 µmol/L vs. 12.0 µmol/L, P=0.005) and IMRcorr (58.0 vs. 36.1, P=0.002). IMRcorr was correlated to TIMI frame (r=0.40, P=0.012) for all cases. The sensitivity and specificity of inferring IMR≥35.3 by TIMI frame were 0.75 and 0.65 (P=0.049) with TIMI frame over 40.5. Conclusions: High IMR may be one of the reasons for chest pain in patients with intermediate coronary stenosis. There is no correlation between vascular risk factors and IMR or CFR, while there is positive correlation between TIMI frame and IMR. The specificity is 65% for inferring IMR rise with TIMI frame over 40.5.

Abstract
Objective: To assess the reliability and validity of the Chinese version of Driving Anger Scale (DAS) in professional drivers in China and provide a scientific basis for the application of the scale in drivers in China. Methods: Professional drivers, including taxi drivers, bus drivers, truck drivers and school bus drivers, were selected to complete the questionnaire. Cronbach's α and split-half reliability were calculated to evaluate the reliability of DAS, and content, contract, discriminant and convergent validity were performed to measure the validity of the scale. Results: The overall Cronbach's α of DAS was 0.934 and the split-half reliability was 0.874. The correlation coefficient of each subscale with the total scale was 0.639-0.922. The simplified version of DAS supported a presupposed six-factor structure, explaining 56.371% of the total variance revealed by exploratory factor analysis. The DAS had good convergent and discriminant validity, with the success rate of calibration experiment of 100%. Conclusion: DAS has a good reliability and validity in professional drivers in China, and the use of DAS is worth promoting in divers.

Abstract
BACKGROUND A previous study provided evidence for a genetic association between PPP2CA on 5q31.1 and systemic lupus erythematosus (SLE) across multi-ancestral cohorts, but failed to find significant evidence for an association in the Han Chinese population. OBJECTIVES To explore the association between this locus and SLE using data from our previously published genome-wide association study (GWAS). METHODS Single-nucleotide polymorphisms (SNPs) rs7726414 and rs244689 (near TCF7 and PPP2CA in 5q31.1) were selected as candidate independent associations from a large-scale study in a Han Chinese population consisting of 1047 cases and 1205 controls. Subsequently, 3509 cases and 8246 controls were genotyped in two further replication studies. We then investigated the SNPs' associations with SLE subphenotypes and gene expression in peripheral blood mononuclear cells. RESULTS Highly significant associations with SLE in the Han Chinese population were detected for SNPs rs7726414 and rs244689 by combining the genotype data from our previous GWAS and two independent replication cohorts. Further conditional analyses indicated that these two SNPs contribute to disease susceptibility independently. A significant association with SLE, age at diagnosis < 20 years, was found for rs7726414 (P = 0·001). The expression levels of TCF7 and PPP2CA messenger RNA in patients with SLE were significantly decreased compared with those in healthy controls. CONCLUSIONS This study found evidence for multiple associations with SLE in 5q31.1 at genome-wide levels of significance for the first time in a Han Chinese population, in a combined genotype dataset. These findings suggest that variants in the 5q31.1 locus not only provide novel insights into the genetic architecture of SLE, but also contribute to the complex subphenotypes of SLE.

Abstract
BACKGROUND Thiopurines, commonly used to treat autoimmune conditions and cancer, can be limited by life-threatening leucopenia. However, whether NUDT15 (nucleoside diphosphate-linked moiety X-type motif 15) is associated with thiopurine-induced leucopenia in Asians is controversial. METHODS Relevant studies in English that were published until July 10, 2016 were identified through PubMed, EMbase, and other web knowledge databases. Study quality was assessed according to the Newcastle-Ottawa Scale (NOS) criteria. Summary risk ratio (RR) and 95% confidence intervals (CI) were estimated based on a fixed-effects model or a random-effects model, depending on the absence or presence of significant heterogeneity. RESULTS Seven studies of 1138 patients met our inclusion criteria. Random-effects model meta-analysis provided evidence that T carriers of NUDT15 c.415C>T were significantly correlated with high incidences of thiopurine-induced leukocytopenia [CT + TT vs. CC: RR = 3.79, 95%CI (2.64 ~ 5.44), P < 0.00001]. This correlation was especially strong in TT patients, where it was found to be significantly increased by 6.54-fold compared with CC patients [TT vs. CC: RR = 6.54, 95%CI (3.34 ~ 12.82), P < 0.00001]. We also found that the NUDT15 c.415C>T variant was common in Asians and Hispanics, but rare in Europeans and Africans; the frequency of the NUDT15 c.415C>T distribution varied substantially by race/ethnicity. CONCLUSION The results of this meta-analysis confirm that NUDT15 c.415C>T may be an important predictor of thiopurine-induced leukocytopenia in Asians. Genotype targeting of NUDT15 c.415C>T before initiating thiopurine treatment may be useful to limit leukocytopenia.

Abstract
Purpose Our objective was to evaluate the birth outcomes of FET from different developmental stage of embryo at freezing (Day 3, Day 5 and Day 6). Methods All vitrified-warmed day 3 (D3) and day 5/6 (D5, D6) embryo transfers during the time period from January 2013 until December 2015 were included in the study. The Birthweight, Low birthweight (LBW), sexual distinction, gestation and for singleton births and twins conceived by FET were compared retrospectively between three cryopreservation strategies utilizing either D3, D5 or D6 embryo freezing. All embryos were vitrified by Dimethylsulfoxide (DMSO), Ethylene glycol (EG) and Sucrose used as Cryoprotectants and using Cryoleaf as the receptacles. Results A total of 993 infants from 771 women. The length of embryos storage was 3-38 months, with a median of 8 months. For singleton, birthweight from D5 and D6 blastocysts transfers were significantly heavier than for D3 cleavage-stage embryos transfers (P =0.0065 P =0.0006). For twins, birthweight from D6 blastocysts transfers were significantly heavier than for D5 blastocysts transfers (P =0.0044), and children born after D3 were at a signigicantly increased risk of being born a LBW. Conclusions Birthweights from FET are influenced by developmental stage of embryos at freezing, which were lower for cleavage-stage embryos transfer than blastocysts transfer after FET in singletons. The birth rate of LBW infants was higher in the twins. The study was small so there may be other factors than cryopreservation which affected outcomes. A higher sample size or a multi-centre prospective randomized design could be used in future studies to corroborate the current findings.

Abstract
Objective: To investigate the influence of different diets on serum protein expression levels of 4-hydroxynonenal (4-HNE), thioredoxin (Trx), thioredoxin reductase (TrxR) and the activities of Trx and TrxR, and to explore the effect of damage to the lung tissue and the underlying mechanisms of different body mass index caused by different diets in the rat models . Method: Healthy clean male SD rats were randomly divided into normal group, emaciation group and fat group, which were raised by different diets for 6 months.Then the rats were sacrificed and the serum and lung tissue were prepared. The levels of 4-HNE, Trx and TrxR in peripheral blood were quantitatively analyzed by enzyme-linked immunosorbent assay(ELISA), and the activities of Trx and TrxR were measured by chemical methods. Results: Compared with the normal group, the lung tissue had more apparent emphysema in the emaciation and the fat groups under light microscope, and more inflammatory cell infiltration in alveolar septum was observed in the fat group.The levels of 4-HNE in the fat group[(24.7±8.7)mg/L]was significantly higher than that in the normal group[(15.4±4.7)mg/L, P<0.05)], but there was no significant difference(P>0.05)in the levels of 4-HNE between the emaciation and the normal groups. The levels of TrxR in the emaciation group[(7.7±1.4)μg/ml]was significantly higher than that in the normal and the fat groups[(6.2±1.1), (4.9±1.4)μg/ml, all P<0.05)]. The level of TrxR in the fat group was significantly lower than that in the normal group(P<0.05); The differences in the levels of Trx among the 3 groups were not significant(P>0.05). The activity of Trx in the emaciation group[(32.4±8.5)×10-3A·min-1·mg-1]was significantly higher than that in the normal group[(19.6±3.3)×10-3A·min-1·mg-1]and the fat group[(11.3±7.5)×10-3A·min-1·mg-1, all P<0.01]. The activity of Trx in the fat group was significantly lower than that in the normal group(P<0.05). The activity of TrxR in the emaciation group[(17.6±4.6)×10-3A·min-1·mg-1]was significantly higher than that in the fat group[(7.8±2.3)×10-3A·min-1·mg-1, P<0.01], but the TrxR activity of the 2 groups showed no significant difference as compared with the normal group(P>0.05). Conclusion: Both high BMI and low BMI can affect the oxidative stress of the body, resulting in increased oxidants and decreased antioxidants, and can cause damage to the lung tissue in the rat models.

Abstract
Objective: To analyze the correlation between retinal vascular calibers, ocular blood flow parameters and internal carotid artery stenosis and to evaluate the effect of internal carotid artery stenosis on ocular blood vessels comprehensively. Methods: A retrospective case-control study. The clinical data of 141 patients who underwent head-and-neck computed tomography (CT) angiography examinations of the ICA were collected at Beijing Friendship Hospital, Capital Medical University from January 2014 to January 2016. According to diagnostic criteria, the patients were divided into four groups: the non-stenosis group, the mild stenosis group, the moderate stenosis group, and the severe stenosis andocclusion group. The retinal vascular caliber was measured in color fundus photograph by IVAN software. Color Doppler ultrasonography was used to measure the parameters of ocular blood flow, including the peak systolic velocity (PSV), end diastolic velocity (EDV), resistance index (RI) and pulsatility index (PI). The enumeration data were analyzed with chi-square test, the measurement data were analyzed with rank-sum test, and the correlation test was performed with spearman. Results: The gender ratio of the patients without stenosis, mild stenosis, moderate stenosis, severe stenosis and occlusion was 12/7, 31/19, 28/25, 12/7, χ2 test was not statistically significant (χ2= 0.79, P=0.85); There was no statistically significant difference between the different groups (χ2= 0.15, P=0.68), the age of four groups were (64.1±8.3), (54.3±14.3), (68.9±11.8) and (59.1±8.0) y, respectively. In the no internal carotid artery stenosis group, the arteries diameter is (164.5±15.6) μm ,the vein diameter is (245.6±20.0) μm and the arteriovenous ratio is 0.7±0.1. There is no difference among the mild stenosis group, moderate stenosis group and the severe stenosis (χ2artery caliber=6.92, Partery caliber=0.08; χ2vein diameter=4.16, Pvein diameter=0.25; χ2arteriolar-venular ratio=1.38,Parteriolar-venular ratio=0.71) . The PSV of central retinal artery in the above groups were (14.6±3.6), (34.4±13.2), (35.7±14.6), (42.3±19.0)cm/s respectively, the data were analyzed by rank-sum test and there was a significant difference (χ2=13.44, P< 0.01) ; The PSV of the posterior ciliary artery in the above groups (17.6±6.5), (15.0±4.6), (13.4±4.3) and (11.0±3.2)cm/s respectively, the data were analyzed by rank-sum test and there was a significant difference (χ2=22.71, P<0.01) , EDV were (5.90±2.2), (5.1±2.1), (4.3±1.5) and (4.3±4.8)cm/s respectively and there was a significant difference (χ2=20.36, P<0.01) .There was a correlation between retinal artery diameter, PSV and EDV of the central retinal artery, PSV and EDV of the posterior ciliary artery and the diameter of the internal carotid artery but without linear correlation.

Abstract
MYBA2 transcription factor (Myb-related gene) affects the coloring in grapevine berry and plays an important role in the biosynthesis of anthocyanin. The MYBA2 gene was cloned from Vitis vinifera L. cv. Cabernet Sauvignon and polyclonal antibodies for VvmybA2 were prepared. The VvmybA2 gene expression patterns were observed in seven tissues (the leaf, stem, flower, bud, root, berry, and tendril) and during the berry development stage at transcriptional and translational levels, respectively. The results indicated that the expression of VvmybA2 was approximately 11-fold higher in the berry than that in the other six tissues, and increased rapidly from 60 days after full bloom reaching a maximum on day 80. Furthermore, both the anthocyanin content and UDP-glucose:flavonoid-3-O-glucosyltransferase (UFGT) gene expression levels increased rapidly 60 days after full bloom. Moreover, correlation analysis indicated that the transcriptional and translational expression levels of the VvmybA2 gene were significantly positively correlated with not only UFGT and DFR genes but also with the anthocyanin content during berry development. These results suggested that VvmybA2 could not only regulate the transcription of both UFGT and DFR but also is involved in the expression of the UFGT gene associated with color determination in grape berries.

Abstract
F-box proteins are critical components of the SKP1-CUL1-F-box (SCF) E3 ubiquitin ligases and involved in the ubiquitin-dependent proteolytic pathway. Dysregulation of F-box protein-mediated proteolysis often leads to human malignancies. F-box only protein 8 (FBX8), a novel component of F-box proteins, is down-regulated in several tumors and closely correlates with tumor progression. However, little is known about its function, regulatory mechanisms and substrates in the progression of colorectal carcinoma (CRC). Combining microRNA (miRNA) assay, functional characterization, mechanistic studies with clinical validation, we identify FBX8 as a CRC metastasis suppressor downstream of miR-223, a metastasis promoting miRNA that is transcriptionally regulated by Myocyte enhancer factor (MEF2A). mTOR is a substrate of FBX8 for ubiquitin-mediated degradation and is required for FBX8 induced cell proliferation and invasion in CRC cells. FBX8 is down-regulated in human CRC tissues and correlates with MEF2A, miR-223 and mTOR expression levels. Notably, low FBX8 expression status in CRC tissues was a significant prognostic factor for poor overall survival of patients. These findings illustrate FBX8 as a metastasis suppressor that functions through mTOR signaling pathway and has significant prognostic power.

Abstract
Previous studies have shown a close correlation between the generation of B cell autoantibodies and imbalances in T lymphocyte subpopulations and the occurrence of disease. In this study, we have analyzed the effects of abnormal expression of CD4+CD25+-regulatory T cells, T lymphocyte subpopulations, immunoglobulins, complement factors, inflammatory factors, and adhesion molecules in the peripheral blood on the occurrence and development of autoimmune disease. Eighty patients with autoimmune disease were randomly (equally) divided into active-stage and stable-stage disease groups (according to pre-defined criteria). Fifty healthy people were recruited to the control group. The above-mentioned indices were detected by flow cytometry, immunity transmission turbidity, and enzyme-linked immunosorbent assay. We observed an obvious decrease in the CD4+CD25+- regulatory T cell, CD4+ cell, CD4+/CD8+ cell, NK cell, C3, and C4 expression in all three groups; however, this decrease was statistically significant in the active-stage group (P < 0.05). Alternately, we observed a significant increase in the expression of CD8+ cells, immunoglobulin (Ig) A, IgG, IgM, tumor necrosis factor-α, interleukin (IL)-10, IL-17, interferon-g, intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin expression in the active-stage group (P < 0.05). Therefore, inflammatory reactions and immune dysfunction occurs during the active-stage of autoimmune disease, and detection of the immune indices and inflammatory and adhesion factors could help evaluate the immune stage in these patients, providing an experimental basis for the determination of disease progression and clinical treatment.

Abstract
OBJECTIVE To study the relationship between gestational glucose, lipid metabolism parameters and fetal distress. METHODS Retrospectively, 82 cases of primipara with fetal distress and 246 cases of primipara without any obstetric complications were analyzed. The latter were treated as control group. All the patients were from the same hospital between January, 2014 and January, 2016. Factors as fasting plasma-glucose (FPG), triglyceride (TG), total cholesterol (TC),high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C) parameters during early pregnancy, blood glucose of fasting, 1 hour and 2 hours in 75 g oral glucose tolerance test (OGTT), at 24 to 28 weeks of gestation, hemoglobin and blood pressure parameters during ante partum were recorded for all the cases while parameters as glucose and lipid, hemoglobin, blood pressure and cesarean section rate were compared between the 2 groups. RESULTS FPG during early gestation, blood glucose of fasting, 1 hour and 2 hours 75 g OGTT during mid gestation, systolic blood pressure and diastolic blood pressure during late gestation in the'fetal distress'group were significantly higher than that of the control group. Hemoglobin during late gestation in the fetal distress group was lower than that of the control group, with statistically significant difference (P<0.05). The rate of cesarean section in the fetal distress group was higher than that in the control group (χ(2)=4.489, P=0.034). CONCLUSIONS High BMI at pre-pregnancy, high blood glucose during early and mid-gestation, high blood pressure and anemia during late gestation were related to the fetal distress group. Cesarean section rate was high for pregnancy women with fetal distress.

Abstract
Single nucleotide polymorphisms (SNPs) in mismatch repair genes, especially in the MLH1 gene, are closely associated with susceptibility to hereditary nonpolyposis colorectal cancer. However, few relevant findings are available regarding the association between sporadic colorectal cancer (SCRC) and SNPs of MLH1 in Chinese patients. Therefore, the present study aimed to describe the pathogenic association between three important MLH1 polymorphisms and SCRC in the Chinese population. Peripheral blood samples from 156 SCRC patients and 311 healthy controls were collected. DNA was purified from peripheral blood, and the V384D, R217C, and I219V polymorphisms were evaluated using high-resolution melting analysis and direct sequencing. The association between the three important MLH1 polymorphisms and clinical pathological features of the SCRC patients was analyzed. In addition, PMS2-MLH1 protein interactions were determined by co-immunoprecipitation (Co-IP) to determine the protein functional alteration induced by these SNPs. Among the three polymorphisms, V384D was significantly associated with the risk of SCRC (OR = 31.36, P < 0.0001). The allele frequencies were 4.81 and 0.16% in the SCRC group. No association was found between SCRC and R217C, or between SCRC and I219V. Moreover, the allele frequency of R217C was significantly higher in the SCRC patients younger than 60 years than in those older than 60 years. Co-IP showed that the MLH1 R217C, V384D, and I219V variants had relative binding abilities with PMS2 of 0.59, 0.70, and 0.80, respectively, compared with the wild-type. These findings suggest that MLH1 V384D could be a promising genetic marker for susceptibility to SCRC.

Abstract
OBJECTIVE To overview the status of social support on older female sex workers (OFSWs) in Qingdao and to better understand the characteristics of this egocentric social support networks. METHODS Ucinet 6 software was used to analyze the characteristics of egocentric social networks which involving 400 OFSWs who were recruited by respondent-driven sampling (RDS) method in Qingdao during March 2014 to June. Structural equation model (SEM) was used for data analysis, fitted test and estimation. RESULTS A total of 400 OFSWs of Qingdao nominated 1 617 social supportive members, and the average size of egocentric social networks of OFSWs was (4.0 ± 1.5). Among all the alter egos (social support network members of the egos), 613 were female sex workers fellows, accounted for the most important part of all the social ties (37.91%). Characteristics of small size and non-relative relationships were seen more obviously among OFSWs with non-local registration and the ratings of emotional support (4.42±2.38) was significantly lower than the tangible support (5.73 ± 1.69) (P<0.05). Result of the SEM showed that homogeneity, joint strength and the network structure were significantly related to the ratings of average support. The total standard effects of which were 0.110, 0.925 and -0.069 respectively. It seemed that homogeneity can affect the degree of support, both directly and indirectly. CONCLUSION OFSWs in Qingdao tended to ask for social support from friends who were also female sex workers. Stronger the joint strength between egos and alters, greater the homogeneity between the two was seen. Tighter relations among the alter egos, higher degree of average social support of the egos were acquired.

Abstract
To investigate genetic diversity and relationships of 101 faba bean (Vicia faba L.), landraces and varieties from different provinces of China and abroad were analyzed by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE). A total of 2625 unambiguous and stable bands from 101 germplasms were detected, and 36 different bands were classified according to the electrophoretic mobility patterns of the proteins as determined by the SDS-PAGE analysis, of which 16 were polymorphic. Besides the common bands, the protein bands of 92, 75, 62, 40, 34, 17, and 13 kDa presented the highest frequencies of 92.08, 90.10, 99.01, 95.05, 95.05, 98.02, and 95.05%, respectively. The other 29 polymorphic protein bands showed higher polymorphism with 16.09 polymorphic bands in average. The genetic similarity of the 101 genotypes tested varied from 0.6111 to 0.9722, with an average of 0.7122. Cluster analysis divided the 101 genotypes into six major clusters, which was consistent with the systematic classification of faba bean done in previous studies. The overall results indicated that SDS-PAGE was a useful tool for genetic diversity analysis and laid a solid foundation for future faba bean breeding.

Abstract
Annual wild soybean (Glycine soja Sieb. et Zucc.), the ancestor of cultivated soybean (G. max), is believed to be a potential gene source for further improvement of soybean to cope with environmental stress. In this study, 10 simple sequence repeat (SSR) markers were used to evaluate the genetic diversity and population genetic structure in five wild soybean populations using 195 accessions collected from Dongying, China. Ten SSR markers yielded 90 bands, with an average of nine bands per marker. The percentage of polymorphic loci (P) was 97.78%, the distribution of expected heterozygosity (HE) was 0.1994-0.4460 with an average of 0.3262, and the distribution from Shannon's information index (I) was 0.3595-0.6506 with an average of 0.5386. The results showed that wild soybean had a high degree of genetic diversity at the species level. Nei's differentiation coefficient (FST) was 0.1533, and gene flow (Nm) was 1.3805, which indicated that genetic variation mainly existed within populations and that there was a certain level of gene exchange between populations. Some genetic differentiation occurred among populations, although this was not significant. Cluster analysis indicated that there was no significant correlation between the genetic structure of wild soybean populations and their geographic distribution, and the clustering results may be relatively consistent with the habitats of the accessions. In the present study, the genetic diversity of wild soybeans showed a broad genetic base and enables suggestions for the conservation of this plant to be made.

Abstract
Anthropogenic activities have seriously impacted wild resources of the Amur sturgeon, Acipenser schrenckii, and more information on local and regional population genetic structure is required to aid the conservation of this species. In this study, we report the development of 12 novel polymorphic microsatellite loci using next-generation sequencing technology, and the genotyping of 24 individuals collected from a sturgeon farm. The results show that the mean number of ob-served alleles per locus is 6.6 (ranging from 2 to 17). Observed and expected heterozygosity values ranged from 0 to 0.958 and from 0.508 to 0.940, respectively. Not a single locus showed significant departure from Hardy-Weinberg equilibrium and no linkage disequilibrium was observed among any pairwise loci. These highly informative microsatellite markers will be useful for genetic diversity and population structure analyses of A. schrenckii and other species of this genus.

Abstract
To investigate the effect on cell proliferation and extracellular matrix expression of annulus fibrosus (AF) cells when co-cultured with bone marrow mesenchymal stem cells (BMSCs). Primary isolated rabbit BMSCs and AF cells were cultured and harvested cells were placed into a 15-mL centrifugal tube co-culture system in a ratio of 2:1 (A group), 1:1 (B group), and 1:2 (C group). Cell proliferation was evaluated using cell counting kit-8, and mRNA of collagen II and mucopolysaccharide was quantified using real-time polymerase chain reaction (PCR) on Days 7, 14, and 21. The cell count, synthesized collagen II and mucopolysaccharide increased in a time-dependent manner, with a peak at Day 21. Cells in Group B proliferated faster and synthesized more collagen II and mucopolysaccharide than groups A and C, where the difference was significant. AF cells and BMSCs in the ratio of 1:1, cultured using the centrifugal tube three-dimensional co-culture system showed that BMSCs can promote AF cell proliferation and extracellular matrix synthesis.

Abstract
Male circumcision is the most frequently performed procedure by urologists. Safety and efficacy of the circumcision procedure requires continual improvement. In the present study, we investigated the safety and efficacy of a new male circumcision technique involving the use of a circular stapler. In total, 879 consecutive adult male patients were randomly divided into 2 groups: 441 underwent stapler circumcision, and 438 underwent conventional circumcision. The operative time, pain score, blood loss volume, healing time, treatment costs, and postoperative complications were compared between the two groups. The operative time and blood loss volume were significantly lower in the stapler group than in the conventional group (6.8 ± 3.1 vs 24.2 ± 3.2 min and 1.8 ± 1.8 vs 9.4 ± 1.5 mL, respectively; P<0.01 for both). The intraoperative and postoperative pain scores were significantly lower in the stapler group than in the conventional group (0.8 ± 0.5 vs 2.4 ± 0.8 and 4.0 ±0.9 vs 5.8 ± 1.0, respectively; P<0.01 for both). Additionally, the stapler group had significantly fewer complications than the conventional group (2.7% vs 7.8%, respectively; P<0.01). However, the treatment costs in the stapler group were much higher than those in the conventional group (US$356.60 ± 8.20 vs US$126.50 ± 7.00, respectively; P<0.01). Most patients (388/441, 88.0%) who underwent stapler circumcision required removal of residual staple nails. Overall, the present study has shown that stapler circumcision is a time-efficient and safe male circumcision technique, although it requires further improvement.

Abstract
Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e^{+}e^{-}→ωχ_{cJ} (J=0, 1, 2). The process e^{+}e^{-}→ωχ_{c0} is observed for the first time, and the Born cross sections at sqrt[s]=4.23 and 4.26 GeV are measured to be (55.4±6.0±5.9) and (23.7±5.3±3.5) pb, respectively, where the first uncertainties are statistical and the second are systematic. The ωχ_{c0} signals at the other seven energies and the e^{+}e^{-}→ωχ_{c1} and ωχ_{c2} signals are not significant, and the upper limits on the cross sections are determined. By examining the ωχ_{c0} cross section as a function of center of mass energy, we find that it is inconsistent with the line shape of the Y(4260) observed in e^{+}e^{-}→π^{+}π^{-}J/ψ. Assuming the ωχ_{c0} signals come from a single resonance, we extract the mass and width of the resonance to be (4230±8±6) MeV/c^{2} and (38±12±2) MeV, respectively, and the statistical significance is more than 9σ.

Abstract
Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of sqrt[s]=4.23, 4.26, and 4.36 GeV, we observe e(+)e(-)→π(0)π(0)hc for the first time. The Born cross sections are measured and found to be about half of those of e(+)e(-)→π(+)π(-)hc within less than 2σ. In the π(0)hc mass spectrum, a structure at 4.02 GeV/c(2) is found. It is most likely to be the neutral isospin partner of the Zc(4020)(±) observed in the process of e(+)e(-)→π(+)π(-)hc being found. A fit to the π(0)hc invariant mass spectrum, with the width of the Zc(4020)(0) fixed to that of its charged isospin partner and possible interferences with non-Zc(4020)(0) amplitudes neglected, gives a mass of (4023.9±2.2±3.8) MeV/c(2) for the Zc(4020)(0), where the first error is statistical and the second systematic.

Abstract
Rapid growth of rigid waste polyurethane (WPUR) foam from refrigerators attracts the attention all over the world. In this study, glycolysis was chosen to treat WPUR from scrapped refrigerators collected in Shanghai, China. Glycolysis reagents and catalysts were selected. The results indicated that the glycolysis efficiency of ethylene glycol (EG) was higher than that of diethylene glycol, and the catalytic efficiency of alkali metal salts (NaOH) was more excellent than that of triethanolamine and organic salts of alkali metal (NaAc). When EG was 100%WPUR as a glycolysis reagent and NaOH was 1%WPUR as a catalyst at a constant temperature of 197.85°C for 2 h, the glycolysis product had the highest glycolysis conversion rate. In order to maximize the recycling of WPUR, regenerative Polyurethane was performed by adding 10% distilled mixed polyol, which conformed to the QB/T 26689-2011 requirements.

Abstract
Pre-selection for fruit skin color at the seedling stage would be highly advantageous, with marker-assisted selection offering a potential method for apple pre-selection. A and MdMYB1 alleles are allele-specific DNA markers that are potentially associated with apple skin color, and co-segregate with the Rf and Rni loci, respectively. Here, we assessed the potential application of these 2 alleles for marker-assisted breeding across 30 diverse cultivars and 2 apple seedling progenies. The red skin color phenotype was usually associated with the MdMYB1-1 allele and A(1) allele, respectively, while the 2 molecular markers provided approximately 91% predictability in the 'Fuji' x 'Cripps Pink' and 'Fuji' x 'Gala' progenies. The results obtained from the 30 cultivars and 2 progenies were consistent for the 2 molecular markers. Hence, the results supported that Rf and Rni could be located in a gene cluster, or even correspond to alleles of the same gene. Our results are consistent with the hypothesis that red/yellow dimorphism is controlled by a monogenic system, with the presence of the red anthocyanin pigmentation being dominant. In addition, our results supported that the practical utilization of the 2 function markers to efficiently and accurately select red-skinned apple cultivars in apple scion breeding programs.

Abstract
BACKGROUND AND AIMS Rhamnogalacturonan II (RGII) is a structurally complex pectic sub-domain composed of more than 12 different sugars and 20 different linkages distributed in five side chains along a homogalacturonan backbone. Although RGII has long been described as highly conserved over plant evolution, recent studies have revealed variations in the structure of the polysaccharide. This study examines the fine structure variability of RGII in wine, focusing on the side chains A and B obtained after sequential mild acid hydrolysis. Specifically, this study aims to differentiate intrinsic structural variations in these RGII side chains from structural variations due to acid hydrolysis. METHODS RGII from wine (Vitis vinifera Merlot) was sequentially hydrolysed with trifluoroacetic acid (TFA) and the hydrolysis products were separated by anion-exchange chromatography (AEC). AEC fractions or total hydrolysates were analysed by MALDI-TOF mass spectrometry. KEY RESULTS The optimal conditions to recover non-degraded side chain B, side chain A and RGII backbone were 0·1 m TFA at 40 °C for 16 h, 0·48 m TFA at 40 °C for 16 h (or 0·1 m TFA at 60 °C for 8 h) and 0·1 m TFA at 60 °C for 16 h, respectively. Side chain B was particularly prone to acid degradation. Side chain A and the RGII GalA backbone were partly degraded by 0·1 m TFA at 80 °C for 1-4 h. AEC allowed separation of side chain B, methyl-esterified side chain A and non-methyl-esterified side chain A. The structure of side chain A and the GalA backbone were highly variable. CONCLUSIONS Several modifications to the RGII structure of wine were identified. The observed dearabinosylation and deacetylation were primarily the consequence of acidic treatment, while variation in methyl-esterification, methyl-ether linkages and oxidation reflect natural diversity. The physiological significance of this variability, however, remains to be determined.

Abstract
Using a sample of 1.3 × 10(9) J/ψ events collected with the BESIII detector, we report the first observation of η(')→π(+)π(-)π(+)π(-) and η(')→π(+)π(-)π(0)π(0). The measured branching fractions are B(η(')→π(+)π(-)π(+)π(-)) = [8.53 ± 0.69(stat.) ± 0.64(syst.)]×10(-5) and B(η(')→π(+)π(-)π(0) π(0)) = [1.82 ± 0.35(stat.) ± 0.18(syst.)] × 10(-4), which are consistent with theoretical predictions based on a combination of chiral perturbation theory and vector-meson dominance.

Abstract
We study the process e+ e- →(D* D*)± π∓ at a center-of-mass energy of 4.26 GeV using a 827 pb(-1) data sample obtained with the BESIII detector at the Beijing Electron Positron Collider. Based on a partial reconstruction technique, the Born cross section is measured to be (137±9±15) pb. We observe a structure near the (D* D*)± threshold in the π∓ recoil mass spectrum, which we denote as the Zc±(4025). The measured mass and width of the structure are (4026.3±2.6±3.7) MeV/c2 and (24.8±5.6±7.7) MeV, respectively. Its production ratio σ(e+ e- → Zc±(4025)π∓ → (D* D*)± π∓)/σ(e+ e- → (D* D*)± π∓) is determined to be 0.65±0.09±0.06. The first uncertainties are statistical and the second are systematic.

Abstract
In this study, the cDNA coding serum transferrin (stf) of Misgurnus anguillicaudatus (mastf) was cloned. mastf cDNA is composed of 2326 bp with a 2007 bp open reading frame encoding 668 amino acids. The deduced Mastf protein consists of a signal peptide, two lobes (N and C-lobes) and signature motifs of transferrin (Tf) family. The results of tissue distribution indicated that mastf mRNA was predominantly expressed in the liver. The results indicate that the mastf expression increased significantly in liver, blood, spleen and head kidney after the challenge with Aeromonas sobria, acting as a positive acute protein, suggesting that mastf is related to the immune response. The cloning and expression analysis of mastf further demonstrates the evolutionary conservation of Stf and immune function in vertebrates.

Observation of e+e- → γX(3872) at BESIII. PHYSICAL REVIEW LETTERS 2014; 112:092001. [PMID: 24655246 DOI: 10.1103/physrevlett.112.092001] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/15/2013] [Indexed: 06/03/2023]
Abstract
With data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies from 4.009 to 4.420 GeV, the process e+e-→ γX(3872) is observed for the first time with a statistical significance of 6.3σ. The measured mass of the X(3872) is (3871.9 ± 0.7s tat ± 0.2 syst) MeV/c(2), in agreement with previous measurements. Measurements of the product of the cross section σ[e+e- → γX(3872)] and the branching fraction B[X(3872)→π+π-J/ψ] at center-of-mass energies 4.009, 4.229, 4.260, and 4.360 GeV are reported. Our measurements are consistent with expectations for the radiative transition process Y(4260) → γX(3872).

Neuroscience 2014; 268:66-74. [PMID: 24607343 DOI: 10.1016/j.neuroscience.2014.02.034] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2013] [Revised: 02/14/2014] [Accepted: 02/21/2014] [Indexed: 10/25/2022]
Abstract
Therapeutic options for hypoxic-ischemic brain damage (HIBD) are scarce and inefficient. Recently, many studies have demonstrated that red photon plays an important role in anti-inflammatory processes as well as apoptosis, the main trait of HIBD. In this study, we investigated whether red photon can protect from HIBD in SD rats and oxygen-glucose deprivation (OGD) in PC12 cells. Apoptosis, mitochondrial transmembrane potential (MMP), and reactive oxygen species (ROS) rates were assessed in PC12 cells. We found that 6-h irradiation resulted in decreased MMP, ROS and apoptosis rates, although these changes were reversible with prolonged irradiation. Importantly, these effects were sustained for 2-8h upon quenching of the red photon. Similar trends were observed for protein and mRNA expression of bax and bcl-2, with short-term irradiation (6h) inhibiting apoptosis in PC12 Cells. However, long-term (>6h) irradiation caused cell damage. In vivo experiments, bax mRNA and protein levels were reduced after 7days in HIBD model rats treated with red photon, in contrast to bcl-2. Furthermore, we found that bax and bcl-2 were mainly expressed in pyramidal cells of the hippocampus CA1 and CA3. Importantly, Morris Water Maze test results revealed an improvement in learning ability and spatial memory in rats after irradiation. Overall, our data showed that short-term irradiation with red photon in the acute phase inhibits the mitochondrial apoptotic pathway via regulation of bcl-2-related proteins and reduction of ROS levels, thereby decreasing apoptosis in nerve cells and improving the neurological prognosis of HIBD.
