Abstract
Objective: To investigate the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and interleukin-1beta (IL-1β) in the plasma and bronchoalveolar lavage fluid of silicosis patients with artificial quartz stone plate processing. Methods: In January 2022, 10 patients with artificial quartz stone plate processing silicosis and 20 patients with common silicosis who were hospitalized and diagnosed in a hospital at Zhejiang Province from June 2019 to December 2021 were retrospectively selected as the research objects, and 30 healthy people were selected as the control group during the same period. Plasma of all subjects and bronchoalveolar lavage fluid of all patients were collected. The levels of TNF-α, IL-6 and IL-1β in plasma and bronchoalveolar lavage fluid were detected by enzyme-linked immunosorbent assay and were analyzed. Results: The levels of TNF-α, IL-6 and IL-1β in the plasma of patients with silicosis were higher than those of the control group (P<0.05), and the levels of TNF-α and IL-1β in the plasma of silicosis patients with artificial quartz stone plate processing were higher than those of common silicosis patients (P<0.05). The levels of TNF-α and IL-1β in plasma of artificial quartz stone plate processing silicosis patients were higher than those of common silicosis patients at the same silicon stage (P<0.05). The levels of IL-1β in bronchoalveolar lavage fluid of silicosis patients with artificial quartz stone plate processing was higher than that of patients with common silicosis (P<0.05) . Conclusion: The levels of TNF-α, IL-6 and IL-1β in silicosis patients with artificial quartz stone plate processing are higher than those in patients with common silicosis, which may be related to dust components they are exposed to.

Abstract
Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Abstract
Objective: To compare the efficacy of thulium fiber laser (TFL) and holmium laser (HL) in the treatment of upper urinary tract stones. Methods: A total of 76 patients diagnosed with upper urinary tract stones by radiographic examination and who required ureteroscopy lithotripsy or retrograde intrarenal stone surgery were prospectively enrolled from the Department of Urology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine between January 2022 and June 2022. Patients were divided into TFL group (n=38) and HL group (n=38) in a 1∶1 ratio according to the randomization schedule. The perioperative outcomes and stone-free rate of two groups were recorded and compared. Results: Finally, the clinical data of 71 patients were completely collected, including 55 males and 16 females, with a mean age of (45.7±14.1) years old. There were 36 patients in TFL group and 35 patients in HL group, and there was no significant difference in age, body mass index, gender, Charlson comorbidity index, stone site, stone location, stone size and stone density between two groups (all P>0.05). All the surgeries were successfully performed with no intraoperative complications. There were no significant differences between the two groups in terms of operation time, stone displacement during lithotripsy, visual field clarity, changes in hemoglobin, leukocyte, and C-reactive protein, and length of postoperative hospital stay (all P>0.05), but the laser action time[M (Q1,Q3)] in the TFL group was 30.0 (20.0, 48.8)s, which was significantly shorter than that in the HL group [90.0 (50.0, 120.0)s, P<0.001]. The stone-free rates of TFL group and HL group were 97.2% (35/36) and 88.6% (31/35), and there was no significant difference (P=0.337). The postoperative complication incidences of TFL group and HL group were 36.1% (13/36)and 22.9% (8/35), respectively, and the difference was not significant either (P=0.221). For ureter stones, the laser action time in TFL group was 22.5 (20.0, 43.8)s, which was significantly shorter than that in HL group [80.0 (50.0, 120.0)s, P<0.001]. For stones with maximum diameter≤10 mm, the laser action time in TFL group was 20.0 (10.0, 25.0)s, which was significantly shorter than that in HL group [50.0 (40.0, 80.0)s, P<0.001]. For stones with maximum diameter>10 mm, the laser action time in TFL group was 60.0(42.5, 180.0)s, which was significantly shorter than that in HL group [180.0(120.0, 210.0)s, P=0.035]. For stones with density≤1 000 CT, the laser action time in TFL group was 30.0 (20.0, 45.0)s, which was significantly shorter than that in HL group [95.0 (47.5, 120.0), P=0.001]. For stones with density>1 000 CT, the laser action time in TFL group was 30.0 (20.0, 90.0)s, which was significantly shorter than that in HL group [80.0 (55.0, 180.0)s, P=0.033]. Conclusion: TFL lithotripsy is an effective and safe surgical procedure for the treatment of upper urinary tract stones, with similar clinical efficacy but shorter laser action time compared to HL lithotripsy.

Abstract
Objective: To explore the correlation between electrical impedance indicators and commonly used nutritional indicators in neurocritical care patients. Methods: A cross-sectional study was conducted to collect 58 neurocritical care patients in neurosurgery Department of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from June to September 2022. Bioelectrical impedance tests were performed after surgery or one week after injury, and nutrition-related biochemical indicators of the patients were collected on the same day, including nutritional status related indicators, inflammation related indicators, anemia related indicators and blood lipid related indicators. The patients were assessed with acute physiology and chronic health evaluation (APACHE) Ⅱ score and sequential organ failure assessment (SOFA) score. Based on the results obtained, the patients were assessed with nutritional score and spearman correlation analysis. The correlations of electrical impedance with nutrition related indicators and nutrition risk related indicators were analyzed. The prediction model of nutritional status was constructed by multi-factor binary logistic regression. Stepwise regression was used to screen electrical impedance indicators related to nutritional status. The receiver operating characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated to evaluate the predictive ability of the nutritional status prediction model. Results: A total of 58 patients were collected, including 33 males and 25 females, and aged 72.0 (59.0, 81.8) years. Extracellular water (ECW) was positively correlated with interleukin 6 (r=0.529, P<0.001). The edema index [ECW/total body water (TBW)] was negatively correlated with albumin (r=-0.700, P<0.001), hematocrit (r=-0.641, P<0.001) and hemoglobin (r=-0.667, P<0.001). The phase angle was positively correlated with albumin (rRA=0.667, rLA=0.649, rRL=0.669, rLL=0.685, all P<0.001), hematocrit (rRA=0.600, rLA=0.604, rTR=0.565, rRL=0.529, rLL=0.602, all P<0.001) and hemoglobin (rRA=0.626, rLA=0.635, rTR=0.594, rRL=0.624, rLL=0.631, all P<0.001). By stepwise regression screening of predictive factors for nutritional status and incorporating age, gender and white blood cells as confounding factors into the model, the final model was obtained as follows: nutritional status=-0.01×age+1.22×gender-0.12×white blood cells+202.20×ECW/TBW+0.5 torso phase angle -82.16 [The OR value of ECW/TBW: 20.8 (95%CI: 3.7-117.1), P<0.001], with the AUC of 0.921. Conclusion: Bioelectrical impedance indicators have good correlations with commonly used clinical nutritional indicators, and can provide a new method for nutritional evaluation of neurocritical care patients.

Abstract
Objective: To analyze the epidemiology and spatial-temporal distribution characteristics of hand, foot and mouth disease (HFMD) in Shanxi province. Methods: The data of HFMD in Shanxi province from 2009 to 2020 were collected from notifiable disease management information system of Chinese information system for disease control and prevention and analyzed by descriptive epidemiology, Joinpoint regression, spatial autocorrelation analysis and spatio- temporal scanning analysis. Results: A total of 293 477 HFMD cases were reported in Shanxi province from 2009 to 2020, with an average annual incidence of 67.64/100 000 (293 477/433 867 454), severe disease rate of 5.36/100 000 (2 326/433 867 454), severe disease ratio of 0.79%(2 326/293 477), mortality of 0.015/100 000 (66/433 867 454), and fatality rate of 22.49/100 000 (66/293 477). The reported incidence rate, severe disease rate, mortality rate and fatality rate of HFMD showed decreasing trends. The main high-risk groups were scattered children and kindergarten children aged 0-5. The incidence of HFMD had obvious seasonal variation, with two peaks every year: the main peak was during June-July, the secondary peak was during September-October and the peak period is from April to November. A total of 13 942 laboratory cases were confirmed, with a diagnosis rate of 4.75% (13 942/293 477), including 4 438 (35.11%, 4 438/293 477) Enterovirus A71 (EV-A71) positive cases, 4 609 (33.06%, 4 609/293 477) Coxsackievirus A16 (CV-A16) positive cases, and 4 895 (31.83%, 4 895/293 477) other enterovirus positive cases. There was a spatial positive correlation (Moran's I ranged from 0.12 to 0.58, all P<0.05) and the spatial clustering was obvious. High-risk regions were mainly distributed in Taiyuan in central Shanxi province, Linfen and Yuncheng in southern Shanxi province, and Changzhi in southeastern Shanxi province. Spatial-temporal scanning analysis revealed 1 the most likely cluster and 8 secondary likely clusters, of which the most likely cluster (RR=2.65, LLR=22 387.42, P<0.001) located in Taiyuan and Jinzhong city, Shanxi province, including 12 counties (districts), and accumulated from April 1, 2009 to November 30, 2018. Conclusions: There was obvious spatial-temporal clustering of HFMD in Shanxi province, and the epidemic situation was in decline. The key areas were the districts in urban areas and the counties adjacent to it. Meanwhile, the monitoring and classification of other enterovirus types of HFMD should be strengthened.

Abstract
Objective: To investigate the correlation between heart rate index (HRI), systolic blood pressure(SBP) peak-to-SBPrest ratio (SBPR) and peak oxygen consumption (peakVO2) in patients with chronic heart failure (CHF), and discuss the possibility of using HRI and SBPR collected during exercise to assess the exercise tolerance of CHF patients in the absence of gas analysis. Methods: In this cross-sectional study, a total of 547 patients with CHF who underwent cardiopulmonary exercise test(CPET) in Tongji Hospital Heart Rehabilitation Center Affiliated to Tongji University from March 2007 to December 2018 were collected retrospectively, focusing on their clinical data including age, gender, type of heart failure,BMI as well as data collected during their CPETs, such as peakVO2, HRI and SBPR. Spearman univariate correlation analysis was used for statistical analysis, to unveil the correlations between peakVO2 and those parameters, and multiple linear regression analysis was also conducted. Results: A total of 547 CHF patients conducting CPET were included in this research, of which 447 were male, at age of 63(56, 69). Univariate analysis indicates that HRI, SBPR and peakVO2 showed significant positive correlation (r=0.323, 0.263, respectively, all P<0.001); Age and peak VO2 showed significant negative correlation(r=-0.207, P<0.001); Male patients showed peakVO2 higher than female(r=-0.229, P<0.001); PeakVO2 of heart failure with reduced ejection fraction(HFrEF) was lower than heart failure with mid-range ejection fraction(HFmrEF)and heart failure with preserved ejection fraction(HFpEF) (r=0.181, P<0.001). Body mass index (BMI) had no significant correlation with peakVO2 (P>0.05). Multivariate linear regression analysis showed that the HRI, SBPR were positively correlated with peakVO2(t=7.68, 5.08, respectively, all P<0.05), while age and BMI showed negative correlation with peakVO2(t=-5.43, -0.31, respectively, all P<0.05). PeakVO2 of male was higher than female(t=-6.03, P<0.05), and peakVO2 of HFrEF was lower than those of HFmrEF and HFpEF(t=3.17, 4.48, respectively, all P<0.05). A linear equation (F=33.52, adjusted R2=0.29) could be constructed: peakVO2=10.65(male) or 8.53(female)+4.26HRI+3.31SBPR-0.07age-0.13BMI+0(HFrEF) or 1.05 (HFmrEF) or 1.62(HFpEF). Conclusion: HRI and SBPR are positively correlated with peakVO2. In the absence of gas analysis, it is possible to apply HRI and SBPR during exercise to predict exercise tolerance in patients with CHF.

Abstract
Objective: To investigate the effect and underlying mechanism of paeoniflorin on hippocampal neuron apoptosis induced by lead acetate. Methods: In September 2020, primary hippocampal neuronal cells were isolated and cultured from fetal rats, and identified using cellular immunofluorescent. MTT assay was used to measure the cell viability to determine the concentration and time of lead acetate-induced hippocampal neuron apoptosis. MTT was also used to evaluate the effect of paeoniflorin concentration on the apoptosis of hippocampal neurons induced by lead acetate. According to the results, different concentrations of paeoniflorin were selected to intervene hippocampal neuron cells, after 24 h, lead acetate was added to the cells, meanwhile, blank and model groups were set up, the content of reactive oxygen species (ROS) , superoxide dismutase (SOD) , lactate dehydrogenase (LDH) , malondialdehyde (MDA) and Caspase-3 were measured. Extracellular signal regulated kinase (ERK) , phosphorylated ERK (p-ERK) , p38 mitogen -activated protein kinases (p38MAPK) , phosphorylated p38MAPK (p-p38MAPK) , c-Jun N-terminal kinase (JNK) and phosphorylated JNK (p-JNK) protein expression in hippocampal neuronal cells were determined by Western blotting. Results: The isolated and cultured hippocampal neurons were identified by immunofluorescence chemical staining and then treated with lead acetate, MTT results showed that lead acetate had the best toxicity effect when treated for 24 h at a concentration of 25 μmol/L. Paeoniflorin showed no cytotoxic effect on hippocampal neuronal cells when the concentrations below 80 μmol/L. Compared with the model group, the activity of hippocampal neuronal cells was significantly increased after treating with 20, 40 or 80 μmol/L paeoniflorin (P<0.05) . Compared with the blank group, the ROS activity, LDH release level, MDA content and caspase-3 content were significantly increased (P<0.01) , and the SOD activity was significantly decreased (P< 0.01) in the hippocampal neuronal cells of the model group. Compared with the model group, the ROS activity, LDH release level, MDA content and caspase-3 content were obviously decreased (P<0.05) , SOD activity was significantly increased (P <0.01) after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin. Relative to the model group, the ratio of p-ERK/ERK were significantly up-regulated (P<0.01) , while the ratios of p-p38MAPK/p38MAPK and p-JNK/JNK were significantly down-regulated after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin (P<0.05) . Conclusion: Paeoniflorin may down-regulate the expression of p-p38MAPK and p-JNK protein, up-regulate the expression of p-ERK protein, and inhibit the apoptosis of hippocampal neurons induced by lead acetate through the MAPK signaling pathway.

Abstract
Objective: To examine the modalities of treatment and clinical outcomes of emphysematous pyelonephritis (EPN), in order to improve the survival rate of EPN patients. Methods: Totally 14 patients diagnosed as EPN between October 2011 and November 2020 at Department of Urology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were included in this article. Data collection including patient demographics, clinical manifestations, management and clinical outcomes were conducted by retrospective charts review, after receiving the institutional review board's approval. There were 11 females and 3 males with a median age of 59 years (range: 52 to 73 years). The lesions were located on the left side in 10 patients and right side in 4 patients. All the 14 patients suffered from fever, and present with severe sepsis or septic shock. The median time from symptom onset to admission to hospital was 3 days(range: 2 to 5 days). All cases had diabetes mellitus. Escherichia coli was the most common organism been cultured (11 cases), while Klebsiella pneumonia was the second (3 cases). CT scan showed bubbly or located gas in the renal parenchyma in 5 cases and presence of steaky or mottled gas in the renal parenchyma in 9 cases. All patients had been admitted to ICU for anti-septic shock therapy. Three patients had undergone percutaneous catheter drainage along with broad-spectrum antibiotics therapy while 3 patients had immediate nephrectomy, the other 8 cases had a combination of an initial percutaneous catheter drainage and second stage nephrectomy. Results: In this case series, 3 patients were died from EPN while the other 11 were survived. The median ICU stay time was 6 days (range: 3 to 11 days). Of the 3 patients died from EPN, 2 had undergone percutaneous catheter drainage along and 1 had received immediate nephrectomy. Among the 11 patients who were survived, only 1 had received percutaneous catheter drainage while the other 10 received nephrectomy (8 patients had staged nephrectomy). Follow-up was performed 6 months after discharge. Of the 11 surviving patients, 2 were lost to follow-up, and the remaining 9 patients had an creatine level of (118.4±29.4) μmol/L (range: 89 to 176 μmol/L). Conclusions: For patients coupled with diabetes who were initially diagnosed as acute pyelonephritis, the possibility of EPN should be considered when the disease progressed rapidly especially septic shock occurred. On the basis of empirical broad-spectrum antibiotics therapy and standardized anti-septic shock treatment, a combination of an initial percutaneous catheter drainage and second stage nephrectomy could be efficacious.

Abstract
The vacuum ultraviolet (VUV) radiation is generated in the strong-field-ionized CO molecules through 2+1 resonance excitation with two-color femtosecond laser pulses. When scanning the relative delay between two pump pulses, the rotational-resolved VUV radiations show periodic oscillations lasting as long as 500 ps. Fourier analysis reveals that these oscillations correspond to rotational beat frequencies of the A2Πi state of CO+, which is the result of multi-channel interference during the resonant excitation process. High resolution of Fourier transform spectra up to 0.067cm-1 allows us to obtain the fine energy levels of the A2Πi state. The theoretical calculation is in good agreement with the experimental observation. This work reveals the rotational coherence of the ionic excited state and shows the prospect of rotational coherence spectroscopy in measuring fine structures of molecular ions.

Abstract
Objective: To compare the postoperative outcomes and urinary continence recovery time between standard robotic-assisted laparoscopic radical prostatectomy (RARP) and Retzius-sparing robotic-assisted laparoscopic radical prostatectomy (RsRARP). Methods: A total of 92 patients with low to intermediate-risk prostate cancer who underwent RARP (n=52) and RsRARP (n=40) in Sir Run Run Shaw Hospital from October, 2016 to January, 2018 were retrospectively reviewed. Perioperative data (operative time, estimated blood loss, complications, postoperative staging, postoperative Gleason score) and surgical outcomes (rate of margin positive, urinary continence recovery time) of RARP and RsRARP group were comparatively analyzed. Results: All 92 cases were successfully performed with robot. RARP group had a significantly shorter mean operative time when compared with that in RsRARP group ((103±23) min vs (130±26) min, P<0.05). The two groups had comparable estimated blood loss ((100±54) ml vs (103±64) ml, P>0.05), rate of postoperative infection (5.8% (3/52) vs 5.0% (2/40), P>0.05) and rate of postoperative urine leakage (3.8%(2/52) vs 2.5%(1/40), P>0.05). The two groups had a comparable rate of margin positive (7.7%(4/52) vs 12.5%(5/40), P>0.05). Compared with RsRARP group, the RARP group had a lower rate of urinary continence recovery immediately after the catheter removing at 1 week, 1 month and 3 months after the operation (all P>0.05). The two group had a comparable rate of urinary continence recovery at 6 months after the operation (P>0.05). Conclusion: The RsRARP technique has a good tumor control and obvious advantage of early urinary continence recovery compared with the standard RARP technique. RsRARP technique is safe and effective for the treatment of localized prostate cancer.

Abstract
Epidemic spreading in heterogeneous networks has attracted great interest in recent years. To capture the significant effect of residence of individuals on epidemic spreading, we consider herein a simple susceptible-infected-susceptible model with random waiting time in heterogeneous networks. We provide the analytical dynamical expressions for the time evolution for infected individuals and find a fractional memory effect of power-law waiting time on anomalous epidemic spreading. This work provides new quantitative insights in describing contagion processes and could help model other spreading phenomena in social and technological networks.

Abstract
Objective: To compare the composition of DJ tube encrustation and original stone, and to discuss the causes and prevention of encrustations. Methods: Twenty-five patients with DJ tube encrustation (1 case of INLAY OPTIMA(®) tube, Bard Medical, 16 cases of Universa(®) Firm tube, Cook Medical, 8 cases of Polaris™ Loop tube, Boston Scientific) in our institution from Januarry 2018 to April 2019 wereretrospective analyzed. Stones and encrustations were analyzed using the Fourier transform infrared spectroscopy analysis system to compare the differences in composition. Results: 76% (19/25) patients had the exact same DJ tube encrustations composition as the original stone component; 24% (6/25) patients had DJ tube encrustation and original stone composition inconsistent (5 cases of calcium oxalate stone, 1 case of apatite carbonate.) It maybe related to the control of urinary tract infection after ureteral obstruction. The earliest DJ tube with encrustation was a pre-expansion tube before flexible-ureteroscopy, and the indwelling time was only 18 days. Conclusions: DJ tubes of different brands and models have the risk of formation of encrustation. Most of the encrustation has the same composition as the original stone. The prevention of DJ tube scorpion can be started from: (1) removing the DJ tube within 6 weeks or replace it regularly when necessary; (2) selecting the appropriate tube including diameter and model; (3) actively controlling urinary tract infection; (4) treating the metabolic diseases, such as hypercalcemia, hyperuricemia, et al, and providing personalized guidance for each patient.

Abstract
Objective: To examine the association of pre-pregnancy obesity, excessive gestational weight gain (GWG) and gestational diabetes mellitus (GDM) with the risk of large for gestational age (LGA), and assess the dynamic changes in population attributable risk percent (PAR%) for having these exposures. Methods: A retrospective cohort study was conducted to collect data on pregnant women who received regular health care and delivered in Beijing Obstetrics and Gynecology Hospital from January to December in 2011, 2014 and 2017, respectively. Information including baseline characteristics, metabolic indicators during pregnancy, pregnancy complications, and pregnancy outcomes were collected. Multivariate logistic regression model was constructed to assess their association with LGA delivery. Adjusted relative risk and prevalence of these factors were used to calculate PAR%and evaluate the comprehensive risk. Results: (1)The number of participants were 11 132, 13 167 and 4 973 in 2011, 2014 and 2017, respectively. Corresponding prevalence of LGA were 15.19% (1 691/11 132), 14.98% (1 973/13 167) and 16.21% (806/4 973). No significant change in the prevalence of LGA was observed across all years investigated (all P>0.05). (2)According to results from multivariate logistic regression model, advanced maternal age, multiparity, pre-pregnancy overweight or obesity, GWG,GDM and serum triglyceride level≥1.7 mmol/L in the first trimester were associated with high risk of LGA (all P<0.05). Among these factors, pre-pregnancy overweight or obesity, excessive GWG and multiparity were common risk factors of LGA. GDM was not associated with risk of LGA in 2017 database. (3) Dynamic change of PAR% in these years were notable. PAR% of GWG for LGA decreased (32.6%, 27.2% and 22.2% in 2011, 2014 and 2017, respectively), while PAR% of pre-pregnancy overweight or obesity showed an upward trend (4.2%, 3.3% and 8.4%). In addition, PAR% of multiparity increased as well (3.5%, 6.3% and 15.9%). (4) Further analysis showed that excessive GWG in the first and second trimesters contributed the most (20.2% and 19.0% in 2014 and 2017). Conclusions: Excessive GWG, pre-pregnancy overweight or obesity and multiparity are the important risk factors what contribute to LGA. PAR% of excessive GWG for LGA decrease in recent years. However, GWG in the first and second trimesters is a critical factor of LGA. Appropriate weight management in pre-pregnancy, the first or second trimester is the key point to reduce the risk of LGA.

Abstract
Objective: To investigate the effect of optimized preoperative dietary management on enhanced recovery in patient with consecutive operation of robot-assisted radical prostatectomy(RARP) at night. Methods: Forty patients undergoing consecutive operation of robot-assisted radical prostatectomy at night in the department of urology in our hospital from Jun 2018 to March 2019 were divided into two groups, 23 patients in the study group and 17 patients in the control group. The control group followed the traditional fasting program at 24∶00 p.m. the day before the surgery. In the study group, the preoperative fasting procedure was optimized. The fasting time, water deprivation time, intravenous infusion volume, scores of hunger and thirst, blood glucose level, length of postoperative hospital stay and adverse reactions were compared between two groups. The level of hunger and thirst were evaluated using the Likert score. Results: The preoperative fasting time and water deprivation time of the study group and the control group were (11.9±4.4 vs 19.3±4.8) h and (6.0±2.9 vs 19.3±4.8) h, respectively (P<0.01). The infusion volume of study group was (406.5±310.5) ml and that of control group (744.1±443.0) ml, the difference was statistically significant (P<0.01). The hunger and thirst scores of the study group were lower than those of the control group before surgery, and the postoperative hospital stay was shorter than the control group (P<0.05). Conclusion: The optimized preoperative dietary management shortens fasting and water deprivation time, reduces the intravenous infusion volume, relieves the hungry and thirsty in patients with consecutive operation of robot-assisted radical prostatectomy at night.

Abstract
Objective: To investigate the regulation of long-chain non-coding RNA-AC024560.2 transfection on the expression of miR-30a-5p and its effect on proliferation and invasion of prostate cancer cells. Methods: qRT-PCR was used to detect the expression of AC024560.2 in 16 prostate cancer tissues and adjacent normal tissues, prostate cancer cell lines and normal prostate epithelial cells. The cells with the lowest expression amount were transfected, and the prostate cancer cells were divided into control group (transfected with negative control plasmid) and experimental group (transfected with plasmid carrying AC024560.2). Bioinformatics predicted possible target genes for AC024560.2. qRT-PCR was used to detect the expression of AC024560.2 and target genes in the transfected cells. Western blot was used to detect the expression of downstream target proteins. Cell proliferation and invasion were analyzed by MTS assay and Transwell invasion assay. Results: The expression levels of AC024560.2 in prostate cancer tissues and adjacent tissues were 1.95±0.22 and 3.87±0.23, respectively (t=6.09, P<0.01). Compared with normal prostate epithelial cells, the expression of AC024560.2 in prostate cancer cell lines was significantly decreased (P<0.05), and the most significant decrease was observed in C4-2B cell lines (P<0.01). Bioinformatics predictions showed that AC024560.2 bond to miR-30a-5p, and miR-30a-5p bond to SIRT1 mRNA. The expression of AC024560.2 in the experimental group increased significantly (P<0.01), the expression of miR-30a-5p decreased significantly (P<0.01), and the expression of SIRT1 mRNA and protein increased significantly (P<0.01). After transfection with AC024560.2, the cell proliferation ability of the experimental group was significantly decreased from day 2 (P<0.05). The invasive numbers of C4-2B cells in the control group and the experimental group were 130.90±14.54 and 43.77±10.01, respectively (t=4.94, P<0.01). Conclusions: AC024560.2 is lowly expressed in human prostate cancer, and may inhibit the proliferation and invasion of prostate cancer cells by regulating the expression of miR-30a-5p and SIRT1 genes. AC024560.2 may be a potential target for the treatment of prostate cancer.

Abstract
Raf kinase inhibitory protein (RKIP) is a well-established metastasis suppressor that is frequently down-regulated in aggressive cancers. However, the impact of RKIP on cancer cell invasion and metastasis in prostate cancer is still elusive. To this end, we overexpressed RKIP in two prostate cancer cell lines. We found that overexpression of RKIP inhibited prostate cancer cells proliferation, migration and invasion. Mechanistically, we found that RKIP overexpression led to down-regula- tion of the NF-kB signaling pathway and inhibition of the epithelial-to-mesenchymal transition, which is important step for cancer metastasis. In addition, overexpression of RKIP can promote drug effects of docetaxel on prostate cancer cell lines. In conclusion, overexpression of RKIP significantly inhibits prostate cancer cell migration and metastasis, and overexpression of RKIP could aid prostate cancer treatment and therapy.

Abstract
Objective: To summarize the experience of renal autotransplantation for severe iatrogenic proximal ureteral damage and renal artery aneurysms in eight patients and to explore the clinical application value of renal autotransplantation. Methods: Two patients of renal artery aneurysms and six patients of severe iatrogenic proximal ureteral damage between January 2010 and March 2018 in our center were retrospectively reviewed. Results: The procedures of eight cases were successful, with immediate return of renal function in the patients. The warm ischemia time was (3±1) minutes, the total operation time was (340±164) min, and the estimated blood loss was (180±60) ml, respectively. For renal artery anastomosis, six patients of severe iatrogenic proximal ureteral damage received end-to-end anastomosis between the internal iliac artery and renal artery, and two patients of renal artery aneurysms were treated with renal artery and internal iliac artery for reconstruction, then end-to-side anastomosis to recipien external iliac artery. A direct ureterovesical anastomosis was performed in seven patients, one patient was received pyeloureteroplasty. No serious complications of blood vessel and ureter were found during perioperative and long-term follow-up. All cases follow-up hitherto have normal renal function and blood pressure. Conclusions: Renal autotransplantation can be appropriate for patients with proximal ureteral loss and complex hilar renal artery aneurysms. In addition, it is able to protect renal functions to the most extent and provides a surgical alterative for complex renal diseases.

Abstract
Objective: To investigate the distribution and drug resistance of pathogens in infected organ donors from donation after the citizen death (DCD). Methods: Clinical data of 217 DCD donors from January 2013 to June 2017 were retrospectively analyzed.The phlegm, urine, blood and drainage fluid from all of the donors were routinely cultured.The infection rate of the donors, the composition ratio of pathogens and the distribution of specimen sources were observed and the drug resistance was analyzed. Results: Of all the 217 donors, 128 were infected and the infection rate was 59%.A total of 218 pathogens were isolated from these infected donors, including 55.5% (121/218) of gram-negative pathogens, 33.5% (73/218) of gram-positive pathogens followed by 11.0% (24/218) of fungi.The pathogenic specimens were mainly derived from sputum samples (72.5%), followed by urine (15.6%). The mainly two gram-negative pathogens were Klebsiella pneumonia and Acinetobacter baumannii.Klebsiella pneumonia exhibited varying degree of resistance to commonly used antibiotics, whereas susceptible to imipenem and meropenem.Acine-tobacterbaumannii was highly resistant to most of the antibiotics, and the drug resistance rate of imipenem and meropenem was over 60%, displaying a tendency of multi-drug resistance.Staphylococcus aureus, as the mainly gram-positive pathogen, was generally resistant to penicillin and clindamycin, but still sensitive to tovancomycin, teicoplanin and linezolid. Conclusions: DCD donors have a high infection rate, and respiratory infection is most common. Gram-negative pathogens are the primary pathogens causing infection in DCD donors.Klebsiella pneumonia maintain susceptible to imipenem and meropenem, while Acinetobacter baumannii reveals a tendency of multi-drug resistance.Gram-positive pathogens are still sensitive to vancomycin, teicoplanin and linezolid.

Abstract
Objective: To analyze and summarize the surgical experience of robotic-assisted laparoscopic partial nephrectomy (RAPN) for treating renal hilar tumors, and assess the efficacy and safety of this surgery. Methods: The clinical data of 22 renal hilar tumor patients who underwent RAPN in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine between September 2015 and September 2017 was analyzed. The patients included 19 males and 3 females, with an average age of (55.6 ±13.0) years old and the age range was 28-75 years. In 13 cases, the tumors were in left kidney, and 9 in the right. There were 10 large tumors (>4 cm diameter), the average tumor size was (3.7±1.9) cm. Preoperative glomerular filtration rate was normal in all cases. Results: The surgery was successfully finished in all of the cases, with no conversion to open surgery. The mean duration of the surgery was 80-270 min, with an average of (134.7±44.5) min. The blood loss was 80-500 ml, with an average of (135.9±130.7) ml, and none of the cases needed intraoperative blood transfusion. The warm ischemia time was 8-25 min, with an average of (18.2±4.0) min. The postoperative length of hospitalization was 7-23 d, with an average of (11.5±4.1) d. Serious gross hematuria occurred in 1 patient, and paroxysmal atrial fibrillation occurred in 1 patient after surgery. The post-operative pathology showed renal clear cell carcinoma in 18 cases, papillary renal cell carcinoma in 2 cases, chromophobe cell carcinoma in 1 case and well differentiated neuroendocrine tumor in 1 case. The tumor resection margin was negative in all cases. Neither local recurrence nor metastasis was observed during a follow-up of 1 to 15 months. Renal function of all the patients was in normal range. Conclusion: RAPN is a safe, useful approach and a minimally invasive operation for treating renal hilar tumors and it owns crucial advantages in complete and accurate resection of the renal hilar tumors and the reconstruction of the kidney.

Abstract
Objective: Investigated the status quo of quality control of cancer chemotherapy in hospitals in Beijing to discover the main problems and provide the improvement measures. Methods: One medical record of cancer chemotherapy was taken every month for examination of quality control, and a total of 10 medical records in each hospital were examined. A total of 756 medical records from 76 hospitals were examined. Results: The results of analysis showed that the overall standardization and quality control of cancer chemotherapy was positively correlated with the grade of hospital. Only 36.8% of the hospitals were equipped with Pharmacy Intravenous Admixture Services (PIVAS). In terms of quality control of chemotherapy and medicine, the department of oncology had better performance than other departments (P<0.01). The scores of quality control of chemotherapy and medicine in the hospitals with clinical specialist pharmacists were 50.6 and 14.5, significantly higher than 47.2 and 12.7 of those without clinical specialist pharmacists (P<0.05). Conclusion: We should focus on the quality control of cancer chemotherapy in secondary hospitals, reinforce the training of oncology specialists, establish the admission system of oncologists, enhance the training of oncology clinical pharmacists and promote the standardization of cancer chemotherapy.

Abstract
We present a novel photovoltaic self-powered gas sensor based on a p-type single-walled carbon nanotube (SWNT) and n-type silicon (n-Si) heterojunction. The energy from visible light suffices to drive the device owing to a built-in electric field (BEF) induced by the differences between the Fermi levels of SWNTs and n-Si.

Abstract
OBJECTIVE To explore the function of tumor derived IgG (tIgG) and whether the tIgG can inhibit T cells activity. METHODS The tIgG was purified from ovarian cancer tissue. The cord blood monocyte cells (CBMC) and cord blood lymphocyte (CBL) were isolate from human umbilical cord blood. The CBMC and CBL were stimulated with phytohaemagg lutinin (PHA) in order to let the CBMC and CBL in the state of proliferation. Carboxyfluorescein succinimidyl amino ester (CFSE) was cultured with CBMC and CBL. CFSE had no cell toxicity, which could penetrate through the cell membrane and combine the intracellular protein. The fluorescence intensity decreased with the proliferation of cells step by step, so the proliferation of these cells could be detected in flow ctytometry. The tIgG which was purified from ovarian cancer tissue was divided into three groups, 1 mg/L group, 10 mg/L group, and 100 mg/L group, and the intravenous immunoglobulin (IVIG) was also divided into three groups too. The CBMC and CBL were treated by tIgG with 1 mg/L, 10 mg/L, and 100 mg/L in order to observe the proliferation of T cells. The cells were treated with IVIG as a positive control group, and the cells were treated with phosphate buffer saline (PBS) as a negative control. The proliferation of CD4+ or CD8+ T cells were detected in CBMC and CBL. The proliferation of the T cells in CBMC and CBL after 64 h and 86 h were detected. RESULTS In the system of CBMC, the tIgG could suppress the proliferation of CD4+ or CD8+ T cells. The results could also be found in the system of CBL. The CD4+ or CD8+ T cells in the group which were treated with PBS were more active than those in the group which were treated with tIgG and IVIG. The suppression in the group which were treated with tIgG, was stronger than that in the group treated with IVIG. In addition, the suppression of T cells in the group which were stimulated with tIgG as 100 mg/L was more effective than that in the group which were stimulated with tIgG as 10 mg/L. This could prove that tIgG had the function of immunomodulation. CONCLUSION The tIgG can be involved in immune escape of cancer.

Abstract
Objective: In this study, a primary culture system for the rat distal pulmonary arterial smooth muscle cell (PASMC) was established to observe the effect of Bortezomib a treatment on the basal intracellular calcium concentration ([Ca(2+) ](i)), store operated calcium entry (SOCE) and Orai-1 expression in rat PASMC. Methods: We employed the primary culture method for the rat distal PASMC including the enzymatically dissociation of PASMC from the freshly isolated distal pulmonary artery and the culture of PASMC. The In Cyte system was used to measure the basal [Ca(2+) ](i) and SOCE after substantial treatment.Orai-1 protein expression in rat pulmonary artery smooth muscle was detected by Western blot. Results: Compared with Hypoxia group, the basal [Ca(2+) ](i) were significantly reduced in Hypoxia+ BTZ group(P<0.01). The basal [Ca(2+) ](i) A340/A380 ratio of Normoxia group was(1.07±0.02). The basal [Ca(2+) ](i) of Hypoxia group was(1.49±0.03); The Hypoxia+ BTZ group was(1.17±0.03). Compared with Hypoxia group, the store operated calcium entry were significantly reduced in Hypoxia+ BTZ group(P<0.01). The SOCE A340/A380 ratio of Normoxia group was(0.56±0.02). The SOCE of Hypoxia group was(0.84±0.02); The Hypoxia+ BTZ group was(0.66±0.02). The level of Orail-1 protein in pulmonary artery smooth muscle of Hypoxia group was (181.5±12.7)% higher than control group which was(100±0)%, (P<0.05). In the Hypoxia+ BTZ group Orai-1 protein expression was recovered(146.7±15.1)%, (P<0.05). Conclusion: Bortezomib inhibit chronically hypoxic enhancement of Orail-1 protein expression, basal [Ca(2+) ](i) and SOCE in rat distal pulmonary arterial smooth muscle cells.

Abstract
Objective: To explore the value of using fasting plasma glucose (FPG) and lipid profiles between 7 and 15 gestational weeks to predict gestational diabetes mellitus (GDM). Methods: The medical records of 2 138 pregnant women who had prenatal care in Beijing Obstetrics and Gynecology Hospital from August 2011 to February 2012 were analyzed retrospectively. According to results of the oral glucose tolerance tests, women were devided into the GDM group (n=240) and the normal group (n=1 898). Maternal characteristics, FPG and lipid levels between 7 and 15 gestational weeks were compared between the two groups. Logistic regression analysis and receiver operator characteristics(ROC) curve were used in the analysis. Results: Potential markers for the prediction of GDM included total cholesterol, triglyceride (TG) , low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratios (LDL-C/HDL-C) , triglyceride to high-density lipoprotein cholesterol ratios (TG/HDL-C) and FPG. After adjustment of confounding factors, age (OR=1.046, 95%CI:1.003-1.090), pre- pregnancy body mass index (OR=1.104, 95%CI: 1.049-1.161), gravidity>3 (OR=1.768, 95%CI:1.071-2.920), FPG (OR=8.137, 95%CI:5.412-12.236), TG (OR=1.460, 95%CI:1.148-1.858) were independently associated with the risk of developing GDM. Equation, PGDM=1/{1+exp[-(-16.542+0.045×age+0.103×pre-pregnancy body mass index+0.551×gravidity>3+2.110×FPG+0.372×TG)]}, was constructed by the logistic regression analysis. Sensitivity (67.5%) and specificity (70.5%) were determined by the calculated risk score, with a cut-off value of 0.11 (area under the curve: 0.751, 95%CI:0.718-0.783, P<0.001). Conclusions: FPG and TG, together with clinical characteristics may have a better predictive value for the risk of GDM.

Abstract
A total of 11 bacterial strains were assayed for bacteria-induced trap formation in the nematode-trapping fungus Arthrobotrys oligospora YMF1·01883 with two-compartmented Petri dish. These strains were identified on the basis of their 16S rRNA gene sequences. Volatile organic compounds (VOCs) of eight isolates were extracted using solid-phase micro-extraction (SPME) and their structures were identified based on gas chromatography-mass spectrometry (GC-MS). At the same time, all isolates were used for quantitative measurement of ammonia by the indophenol blue method. The effects of pure commercial compounds on inducement of trap formation in A. oligospora were tested. Taken together, results demonstrated that the predominant bacterial volatile compound inducing trap formation was ammonia. Meanwhile, ammonia also played a role in other nematode-trapping fungi, including Arthrobotrys guizhouensis YMF1·00014, producing adhesive nets; Dactylellina phymatopaga YMF1·01474, producing adhesive knobs; Dactylellina cionopaga YMF1·01472, producing adhesive columns and Drechslerella brochopaga YMF1·01829, producing constricting rings.

Abstract
In this study, we sequenced the complete mitochondrial DNA of Chinese indigenous Jinhu Black-bone and Rugao chickens. The two chicken mitochondrial genomes were deposited in GenBank under accession Nos. KP742951 and KR347464, respectively. The complete mitochondrial genomes of Jinhu Black-bone and Rugao chickens were sequenced and found to span 16,785 and 16,786 bp, respectively, and consisted of 22 tRNA genes, two rRNA genes (12S rRNA and 16S rRNA), 13 protein-coding genes, and one control region (D-loop). The majority of genes were positioned on the H-strand, and the ND6 and eight tRNA genes were found to be encoded on the L-strand. The mitogenomes showed a similar gene order to that of the published Gallus gallus genome, as neither included a control region. The overall base composition of the genome of the two chickens was A = 30.22/30.28%, G = 13.57/13.49%, T = 23.74/23.76%, and C = 32.48/32.48%. Nucleotide skewness of the coding strands of the two chicken genomes (AT-skew = 0.12, GC-skew = -0.41) was biased towards T and G. Phylogenetic analysis revealed 29 subspecies, and the molecular genetic relationship among the 29 subspecies was identical to that of traditional taxonomy.

Abstract
In this study, a facile and inexpensive and self-assembled strategy to massively fabricate Ni/Co layered double hydroxides (LDHs) is developed under mild reaction conditions (55 °C). The resulting composite material displays a special three-dimensional hierarchical microsphere structure with well-defined flower-like configuration. The fabrication mechanism can be ascribed to stepwise and regular reaction process of nanoparticles and nanosheets gradually growing to nanopetals and then assembling into flower-like microspheres, based on the systematically investigation of various reaction factors including the Ni:Co feeding ratio, the reaction time and the initial pH-value. Because of its large surface, ultrathin feature and synergetic results of this Ni/Co LDHs nanosheets (20 nm), these Ni/Co-LDHs microspheres deliver an excellent capacitance value about 2228 F·g(-1) (1 A·g(-1)). An all-solid-state flexible asymmetric supercapacitor is designed and assembled by exploiting this Ni/Co-LDHs as the positive materials, which exhibits energy density of 165.51 Wh·kg(1-) at 1.53 KW·kg(1-). It may have vast potential significance in personal wearable equipment. Moreover, this monolithic design provides a promising approach for large scale fabrication of other LDHs materials.

Abstract
Elemental carbon (EC) and polycyclic aromatic compounds (PACs) are potential proxies for the reconstruction of change in human activities and the origin of air masses in historic times. In this study, the historic deposition of char and soot (the two subtypes of EC) and PACs in a 150-year sediment core from different topographic subbasins of Lake Qinghai on the Qinghai Tibetan Plateau (QTP) were reconstructed. The objective was to explore how the variations in the concentrations of EC and PACs, in the ratios of char to soot and of oxygenated polycyclic aromatic hydrocarbons (OPAHs) to parent PAHs, and in the composition of the PAC mixtures reflect historical changes in climate and human activity and the origin of air masses arriving at the QTP. The deposition fluxes of soot in the different subbasins were similar, averaging 0.18 (range of 0.15-0.25) and 0.16 (0.13-0.23) g m(-2) year(-1), respectively, but they varied for char (averaging 0.11 and 0.22 g m(-2) year(-1), respectively), suggesting ubiquitous atmospheric deposition of soot and local river inputs of char. The different vertical distributions of the char/soot ratios in the different subbasins can be interpreted in terms of the different transport mechanisms of char and soot. An abrupt increase in soot concentrations since 1980 coincides with results from the QTP ice cores that were interpreted to be indicative of soot transport from South Asia. Similar concentration patterns of PAHs with soot and 9,10-anthraquinone/anthracene (9,10-AQ/ANT) ratios all >2.0 suggest regional PAC sources. Increasing PAH/soot ratios and decreasing 9,10-AQ/ANT ratios since the beginning of the 1970s indicate increasing local emissions. The historical trends of these diagnostic ratios indicate an increase in the fossil-fuel contribution since the beginning of the 1970s. The increase of perylene concentrations with increasing core depth and the ratio of perylene to its penta-aromatic isomers indicate that perylene originates mainly from in situ biogenic diagenesis. We demonstrate that the concentrations of EC, char, soot, and PACs in sediments can be used to reconstruct local, regional, and remote sources and transport pathways of pollutants to the QTP.

Abstract
We first reported Alternaria heveae (E.G. Simmons ) to be the pathogen that caused black leaf spot of rubber tree (Hevea brasiliensis Muell. Arg) in Heikou county in July 2014 (1). Black leaf spots that resembled the symptoms caused by A. heveae were observed on the leaves of rubber trees of the whole propagule collection nursery in Jingping County (22°68' N and 103°05' E) of Yunnan Province. Black foliar spots (0.1 to 2 mm in diameter) surrounded by a yellow halo with lesions slightly sunken on the leaf surface were observed. To confirm whether the disease was caused by the same pathogen, 5-mm2 sections were removed from the leading edge of the lesion and were surface-sterilized in 75% ethanol, air-dried, plated on potato carrot agar (PCA), and incubated at 28°C in the dark. Colonies of the fungus on PCA had round margins and little aerial mycelia with gray-black coloration after 6 days of growth on PCA (2). Medium brown conidia were found to be in short chains of two to eight spores, ovoid, obclavate, and obpyriform, with or without a short conical or cylindrical-shaped apical beak. Conidia ranged from 22.5 to 67.5 μm long (mean 39.9 μm) × 10 to 15 μm wide (mean 12.5 μm; 100 colodia were measured), with three to six transverse septa and zero to three longitudinal or oblique septa. Morphological characteristics matched the descriptions of A. alternata [(Fries) Keissler] (4).The ITS1-5.8S-ITS2 region of one single-spore isolate, Ah02JP1, was amplified with primers ITS1 and ITS4. The PCR product was sequenced directly and deposited in GenBank (Accession No. KM111289). A BLAST search of the GenBank database revealed 100% similarity with A. alternata isolates KJ829535.1, KJ677246.1, and KF813070.1. Therefore, the pathogen was identified as A. alternata on the basis of its morphological characteristics and ITS sequence. Pathogenicity of a representative isolate, Ah02JP1 was confirmed using a field rubber tree inoculation method. Three rubber plants (the clone of rubber tree Yunyan77-4) were grown to the copper-colored leaf stage. Leaves were spray-inoculated (104 conidia per milliliter spore suspension) until drops were equally distributed using a manual pressure sprayer. Three rubber plants sprayed with sterile distilled water were used as controls. After inoculation, the plants were covered with plastic bags to maintain high relative humidity. The plastic bags were removed 2 days post-inoculation (dpi), and the plants were monitored daily for symptom development. Five days post-inoculation, spots similar to the original ones seen on the field trees developed on all inoculated leaves, while control leaves remained symptomless. A. alternata was re-isolated from spray-inoculated leaves, confirming Koch's postulates. A. alternata has been reported as the causal agent of leaf blight of rubber tree in India, which initially appeared as minute spots on leaves and enlarged with the growth of the leaves (3). However, in the present study, the symptoms (black leaf spots) remained small over time after inoculation. To our knowledge, this is the first report of A. alternata on rubber tree in China. Correct identification of pathogens is essential for disease management strategies. This report will establish a foundation for the further study of Alternaria alternata to address the disease effectively. References: (1) Z. Y. Cai et al. Plant Dis. 98:1011, 2014. (2) E. Mirkova. J.

Abstract
Fe(II)-doped TiO2 spherical shell catalyst was synthesized by one-pot hydrothermal method. The photocatalytic removal of Cr(VI) from plating wastewater under sunlight of the catalyst was demonstrated. It was found that the removal effectiveness of about 99.99% for initial Cr(VI) concentration of 102.3 ppm and 99.01% for 153.4 ppm under 3h sunlight irradiation is realized. The Fe(II) ions serve not only as reducing agents for reducing the Cr(VI) to Cr(III) but also as an intermedium of a two-step reduction, in which the TiO2 photoreduces the Fe(II) ions to Fe atoms firstly, and then the Fe atoms reduce the Cr(VI) to Cr(III). The improved photocatalytic activity of the catalyst is considered due to the synergistic effect of a multi reducing process by Fe(II) doping. The extended optical response and effectively utilization of sunlight of the special spherical-shell-like morphology also contribute to the enhanced photocatalytic activity.

Abstract
Growth hormone (GH) has diverse functions in animals, together with other hormones from the somatotropic axis. Here, chicken GH (cGH) was investigated in recessive white chickens and Qingyuan partridge chickens as a candidate gene affecting egg production traits. Chicken egg production traits were studied in association with 4 selected single nucleotide polymorphisms (T185G, G662A, T3094C, and C3199T). Genotyping was performed by the polymerase chain reaction-ligase detection reaction method. T185G was significantly associated with the egg production traits of body weight at first egg (BW), egg weight at first egg (EW), and the total egg production of 300-day old birds (EN 300). T3094C was also significantly associated with certain egg production traits; however, it affected the 2 breeds differently. Haplotypes of the 4 single nucleotide polymorphisms were also significantly associated with egg production traits of chicken age at first egg laying, BW, EW, and EN 300. H1H6 was the most advantageous diplotype for egg production. We putatively concluded that polymorphisms in the cGH gene and its haplotypes could be used as potential molecular markers for egg production traits to enhance the breeding programs of indigenous chickens.

Abstract
Rubber tree (Hevea brasiliensis Muell. Arg.) is an important industrial crop of tropical areas for natural rubber production. In October 2013, foliar spots (0.1 to 0.4 mm in diameter), black surrounded by a yellow halo, and with lesions slightly sunken were observed on the rubber tree leaf in a growing area in Heikou County of Yunnan Province. Lesion tissues removed from the border between symptomatic and healthy tissue were surface sterilized in 75% ethanol and air-dried, plated on PDA plates, and incubated at 28°C with alternating day/night cycles of light. The pathogen was observed growing out of many of the leaf pieces, and produced abundant conidia. Colonies 6.1 cm in diameter developed on potato carrot agar (PCA) after 7 days, with well-defined concentric rings of growth. Colonies on PCA were composed of fine, dark, radiating, surface and subsurface hyphae. Conidia produced in PCA culture were mostly solitary or in short chains of 2 to 5 spores, long ovoid to clavate, and light brown, 40 to 81.25 × 8 to 20 μm (200 colonies were measured), with 3 to 6 transverse septa and 0 to 2 longitudinal or oblique septa. Morphological characteristics were similar to those described for Alternaria heveae (3,4). A disease of rubber tree caused by Alternaria sp. had been reported in Mexico in 1947 (2). DNA of Ah01HK13 isolate was extracted for PCR and sequencing of the ITS region with ITS1 and ITS4 primers was completed. From the BLAST analysis, the sequence of Ah01HK13 (GenBank Accession No. KF953884), had 97% similarity to A. dauci, 96% identical to A. macrospora (AY154701.1 and DQ156342.1, respectively), indicating the pathogen belonged to Alternaria genus. According to morphological characteristics, this pathogen was identified as A. heveae. Pathogenicity of representative isolate, Ah01HK13 was confirmed using a field rubber tree inoculation method. Three rubber plants (the clone of rubber tree Yunyan77-4) were grown to the copper-colored leaf stage and inoculated by spraying spore suspension (concentration = 104 conidia/ml) to the copper-colored leaves until drops were equally distributed on it using manual pressure sprayer. Three rubber plants sprayed with sterile distilled water were used as controls. After inoculation, the plants were covered with plastic bags. The plastic bags were removed after 2 days post-inoculation (dpi) and monitored daily for symptom development (1). The experiment was repeated three times. The typical 0.1 to 0.4 mm black leaf spots were observed 7 dpi. No symptoms were observed on control plants. A fungus with the same colony and conidial morphology as A. heveae were re-isolated from leaf lesions on inoculated rubber plants, but not from asymptomatic leaves of control plants, fulfilling Koch's postulates. Based on these results, the disease was identified as black spot of rubber tree caused by A. heveae. To our knowledge, this is the first report of A. heveae on rubber tree in China.

Abstract
Peach gummosis represents a significant global disease of stone fruit trees and a major disease in the south peach production area of the Yangtze River of China. In this study, the carbohydrate composition of peach shoots during infection by Lasiodiplodia theobromae was examined. The expression of genes related to metabolic enzymes was also investigated. Control wounded and noninoculated tissue, lesion tissue, and wounded and inoculated surrounding lesion tissue of peach shoots were analyzed. Soluble sugars, glucose, mannose, arabinose, and xylose significantly increased in inoculated tissues of peach shoots compared with control tissues at different times after inoculation. Accumulation of polysaccharides was also observed by section observation and periodic acid Schiff's reagent staining during infection. Analysis using quantitative reverse-transcription polymerase chain reaction revealed that the abundance of key transcripts on the synthesis pathway of uridine diphosphate (UDP)-D-glucuronate, UDP-D-galactose, and UDP-D-arabinose increased but the synthesis of L-galactose and guanosine diphosphate-L-galactose were inhibited. After inoculation, the transcript levels of sugar transport-related genes (namely, SUT, SOT, GMT, and UGT) was induced. These changes in sugar content and gene expression were directly associated with peach gum polysaccharide formation and may be responsible for the symptoms of peach gummosis.

Abstract
We report the fabrication of VO2(M) nanocrystals by direct thermal oxidation V2O3 nanocrystals. The controlling of the thermal oxidation temperature and vacuum is essential for obtaining pure VO2(M) nanocrystals. The VO2(M) nanocrystals have nearly a spherical morphology with sizes ranging from 50 to 80 nm and well dispersed. The phase transition temperature is about 65 degrees C with relatively narrow endothermic and exothermal peaks in DSC curve. Variable temperature resistance and infrared transmission measurements demonstrate a reversible phase transition of the VO2(M) nanocrystals. Our method is facile, economical and can be easily scaled-up for mass production.

Abstract
The production of SERS-active substrates which are uniform, sensitive, reproducibile and durable still remains an important issue. Here, we report a strategy for the fabrication of a large-area Ag-decorated TiO₂ nanograss SERS-active substrate by a simple solvothermal approach combined with Ag evaporation. The nanograss consists of dense rutile TiO₂ nanorods of about 5 nm in diameter and the decorated Ag nanoparticles are an average of 8 nm in diameter. The Ag protrusions and gaps between them contribute to three dimensional SERS "hot spots" which can be modulated by simply controlling the Ag evaporating parameters. The Ag-decorated TiO₂ substrate is highly efficient in detecting rhodamine 6G (R6G) and 4-aminothiophenol (4-ATP) molecules and has good homogeneity. An obvious red shift and even high enhancement of b₂ vibration mode were observed in detecting 4-ATP due to the effective charge transfer from the Ag atoms to sulfur atoms. The Ag-decorated TiO₂ substrate can be easily self-cleaned and reactivated by visible light irradiation without obvious degeneration of SERS signals. Our results demonstrate that the Ag-decorated TiO₂ substrate with high and homogeneous SERS activity has potential feasibility as a sensitive SERS probe.

Abstract
A physiologically based pharmacokinetics model was developed to predict tulathromycin concentrations in edible swine tissues. Physiological parameters included volumes of and plasma flows through different tissues which were obtained from the literatures. The tissue/plasma partition coefficient was calculated according to the area method, and the model was validated through a comparison of predicted and observed concentrations. Withdrawal times in different tissues were predicted. The physiologically based pharmacokinetics model presented here provided accurate predictions of the observed concentrations in all tissues. The results showed that the injection site had the longest withdrawal time (21 days), followed by skin together with fat (19 days) and then kidney (10 days), lung (6 days), liver (4 days) and muscle (1 day). A withdrawal time of 21 days was finally predicted for tulathromycin in swine after a single intramuscular injection at 2.5 mg/kg body weight.

Abstract
We report the synthesis and photocatalytic removal of Cr(VI) from water of hierarchical micro/nanostructured Fe(2+)/TiO(2) tubes. The TiO(2) tubes fabricated by a facile solvothermal approach show a three-level hierarchical architecture assembled from dense nanosheets nearly vertically standing on the surface of TiO(2) microtube. The nanosheets with a thickness of about 20 nm are composed of numerous TiO(2) nanocrystals with size in the range of 15-20 nm. Ferrous ions are doped into the hierarchical architecture by a reduction route. The Fe(2+)/TiO(2) catalyst demonstrates an effective removal of Cr(VI) from water under UV light and the removal effectiveness reaches 99.3% at the initial Cr(VI) concentration of 10 mg L(-1). The ferrous ion in the catalyst serves not as the photo-electron trap but as an intermedium of a two-step reduction. The TiO(2) photoreduces the Fe(2+) ions to Fe atoms firstly, then the Fe atoms reduce the Cr(VI) to Cr(III), and the later is removed by adsorption. The hierarchical architecture of the catalyst serves as a reactor for the photocatalytic reaction of Cr(VI) ions and an effective absorbent for the removal of Cr(III) ions. The catalyst can be easily magnetically separated from the wastewater after photocatalytic reaction and recycled after acid treatment.

Abstract
Ubiquitin (UB) is a conserved protein that regulates a number of processes in eukaryotic cells. Nearly all lepidopteran baculoviruses encode UB homologs showing a partial sequence identity with human UB (Hu-UB). In this study, the sequence, predicted 3D-structure and subcellular localization of UB homologs encoded by two different nucleopolyhedroviruses of Bombyx mori (BmNPV) and Helicoverpa armigera (HaNPV) were compared. UBs of BmNPV and HaNPV (Bm-UB, Ha-UB, respectively) shared only 73% of sequence identity of the different aa in relation to Hu-UB being localized in non-conserved parts, namely in two heterogeneous regions of aa 15-32 and aa 53-60. Interestingly, Bm-UB and Ha-UB share the same seven lysines except for an additional Lys54 in Bm-UB. However, in spite of the sequence heterogeneity, Bm-UB and Ha-UB have a similar predicted 3D-structure. A difference in their subcellular localization during virus growth in insect cell lines was found in the late stage of formation of occlusion-derived virus (ODV). In particular Bm-UB was localized mainly and evenly in the nucleus, while Ha-UB on the nuclear membrane. These data suggest that (i) UBs, besides being engaged in various cellular processes, have a role in specific processes of virus growth, and (ii) Bm-UB and Ha-UB may show certain different activities associated with the virus growth.

Abstract
During their synthesis, many water-soluble proteins and nearly all membrane proteins transit through a protein-conducting channel in the membrane, the Sec translocon, from where they are inserted into the lipid bilayer. Increasing evidence indicates that folding of the nascent protein begins already within the ribosomal exit tunnel in a sequence- and environment-dependent fashion. To examine the effects of the translocon on the nascent-chain folding, we have calculated the potential of mean force for α-helix formation of a 10-alanine oligopeptide as a function of its position within the translocon channel. We find that the predominant conformational states, α-helical and extended, reflect those found for the peptide in water. However, the translocon, via its surface properties and its variable diameter, shifts the equilibrium in favor of the α-helical state. Thus, we suggest that the translocon facilitates not only the insertion of membrane proteins into the bilayer but also their folding.

Abstract
Excellent photoconductive properties have been found in Sb(2)O(3) nanobelts synthesized by a surfactant-assisted solvothermal method. Visible-light photodetectors have been designed from Sb(2)O(3) nanobelt networks using micrometer-wide gold wires as masks. Photodetectors show high sensitivity to visible light, high stability, and reproducibility. Fast response and decay times (<0.3 s) are comparable or even better than these parameters in many other metal oxide nanoscale photodetectors. The dominant mechanism of excellent photoconductivity is attributed to the barrier height modulations in the nanobelt-to-nanobelt contact regions. These results demonstrate that Sb(2)O(3) nanobelt networks can indeed serve as high-performance photodetectors in the visible light range.
