Abstract
The evolution of dispersal modes has been proposed to promote the diversification of angiosperms. However, little is known about the relative impact of different dispersal modes on plant diversification. We test the association between dispersal modes and diversification rates using Rhamnaceae, the cosmopolitan buckthorn family, as a model. We found that species with diplochory have the highest diversification rates followed by those with myrmecochory and ballistic dispersal, while lineages dispersed by vertebrates and wind have relatively low diversification rates. The difference in diversification rates may be closely linked to the difference in dispersal distance and ecological interactions implied by each dispersal mode. Species which disperse over larger geographical distances may have much higher speciation rates due to the increased chance of establishing isolated populations due to geological barriers or habitat fragmentation. However, long-distance dispersal may also increase the chance of extinction. By contrast, species with short-distance dispersal modes may have low speciation rates. Complex interactions with the surrounding environment may, however, impact diversification rates positively by increasing plant survival and reproductive success.

Abstract
Objective: To analyze the survival of nasopharyngeal carcinoma patients in Qidong from 1972 to 2016, and provide a basis for the prognosis evaluation and prevention for nasopharyngeal carcinoma patients. Methods: A total of 1 060 registered nasopharyngeal carcinoma patients were followed up for survival outcomes until December 31, 2021. Observed survival rate (OSR) and relative survival rate (RSR) was calculated by Hakulinen method in SURV3.01 software, and Hakulinen's likelihood ratio test was used for statistical difference comparison. Age-standardized relative survival rate (ARSR) was calculated according to the International Cancer Survival Standard (ICSS). Joinpoint 4.7.0.0 software was used to conduct the annual average percentage change (AAPC) in nasopharyngeal carcinoma survival rate. The period from 1972 to 2016 is divided into 9 periods for grouping processing according to 5 years. Results: The OSR of nasopharyngeal carcinoma at 1, 5, 10 years were 63.02%, 34.70% and 24.72%, the RSR at 1, 5, 10 years were 64.44%, 38.98% and 31.64%, respectively. The uptrends of RSR in the nine periods were statistically significant (χ(2)=112.16, P<0.001). The 1, 5, 10 years RSR for males were 62.66%, 35.89% and 27.94%, while the 1, 5, 10 years RSR for females were 68.30%, 45.67% and 39.68%, respectively. There was no statistically significant difference in RSR between males and females (χ(2)=14.16, P=0.656). The 5-year RSR for the age groups of 25-34, 35-44, 45-54, 55-64, 65-74, and over 75 years old were 52.83%, 40.92%, 42.64%, 38.65%, 27.23% and 28.88%, respectively. There was a statistically significant difference in RSR among different age groups (χ(2)=42.33, P=0.003). Moreover, the ARSR of nasopharyngeal carcinoma at 1, 5, 10 years were 63.64%, 37.33% and 27.10%, for males were 61.82%, 35.60% and 25.20%, for females were 68.36%, 43.12% and 32.93%. Period trend showed that the AAPC of 5-ARSR was 2.71% (t=7.47, P<0.001) from 1972 to 2016 in Qidong. The AAPC of 5-ARSR in males and females were 2.63% (t=4.98, P=0.002) and 2.71% (t=6.08, P=0.001). There was statistically significant increase in 5-year ARSR among both genders. Furthermore, the AAPC of 5-year RSR among 25-34, 35-44, 45-54, 55-64, 65-74 and 75+ years old were 2.16% (t=4.28, P=0.004), 3.38% (t=5.06, P=0.001), 1.99% (t=2.82, P=0.026), 2.82% (t=3.39, P=0.012), 2.20% (t=2.82, P=0.026) and -0.91% (t=-0.42, P=0.689), respectively. Except for the 75+ years old age group, the other age groups were significantly upward trend. Conclusions: The overall survival rate of nasopharyngeal carcinoma in Qidong from 1972 to 2016 has shown an upward trend. It is necessary to introduce standardized multi-disciplinary treatment mode to improve treatment effect and survival rate.

Abstract
Objective This study aimed to provide a realistic observation of survival by major site for 48,866 cancer patients treated at a tertiary cancer hospital in a rural area of China. Methods Patients with cancer registered between 2007 and 2017 in the Nantong rural area were followed up. The starting date for survival calculation was the date of the first diagnosis of cancer at the Nantong Tumor Hospital, and the closing date was December 31, 2020. Observed survival (OS) was analyzed according to ICD-10 site, sex, age, region, and hospitalization period using the life table method and compared using the Wilcoxon (Gehan) statistic. Results The overall 5-year OS rate was 40.48% for all 48,866 patients, 30.19% for males, and 51.90% for females. The top five cancer sites, accounting for 60.51% of the total cases, were the esophagus, lung, stomach, liver, and cervix, with 5-year OS rates of 33.72%, 18.64%, 32.10%, 19.04%, and 71.51%, respectively. The highest 5-year OS was observed in the thyroid (87.52%) and the lowest was in the pancreas (6.37%). Survival was significantly higher in younger patients than in older patients, with 5-year OSs of 69.26% and 19.84% in those aged 20-29 and 90-99 years, respectively. Five-year OSs improved significantly from 39.35% in 2007-2011 to 41.26% in 2012-2017. Conclusion Overall survival improved over the years, although the improvement at some sites was not significant. The observed survival varies from region to region, reflecting differences in the patterns of major sites, disparities in proportions of hospitalization, and demographic characteristics.

Abstract
Objective: To analyze the incidence and survival rate of liver cancer cases in the entire population in the Qidong region from 1972 to 2019, so as to provide a basis for prognosis evaluation, prevention, and treatment. Methods: The observed survival rate (OSR) and relative survival rate (RSR) of 34 805 cases of liver cancer in the entire Qidong region population from 1972 to 2019 were calculated using Hakulinen's method with SURV3.01 software. Hakulinen's likelihood ratio test was used for statistical analysis. Age-standardized relative survival (ARS) was calculated using the International Cancer Survival Standard. The Joinpoint regression analysis was performed with Joinpoint 4.7.0.0 software to calculate the average annual percentage change (AAPC) of the liver cancer survival rate. Results: 1-ASR increased from 13.80% in 1972-1977 to 50.20% in 2014-2019, while 5-ASR increased from 1.27% in 1972-1977 to 27.64% in 2014-2019. The upward trend of RSR over eight periods was statistically significant (χ (2) = 3045.29, P < 0.001). Among them, male 5-ASR was 0.90%, 1.80%, 2.33%, 4.92%, 5.43%, 7.05%, 10.78%, and 27.78%, and female 5-ASR was 2.33%, 1.51%, 3.35%, 3.92%, 3.84%, 7.18%, 11.45%, and 29.84%, respectively. There was a statistically significant difference in RSR between males and females (χ (2) = 45.68, P < 0.001). The 5-RSR for each age group of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 4.92%, 5.29%, 8.17%, 11.70%, 11.63%, and 9.60%, respectively. There were statistically significant differences in RSR among different age groups (χ (2) = 501.29, P < 0.001). The AAPC in Qidong region from 1972 to 2019 for 1-ARS, 3-ASR, and 5-ARS were 5.26% (t = 12.35, P < 0.001), 8.10% (t = 15.99, P < 0.001), and 8.96 % (t = 16.06, P < 0.001), respectively. The upward trend was statistically significant in all cases. The AAPC of 5-ARS was 9.82% in males (t = 14.14, P < 0.001), and 8.79% in females (t = 11.48, P < 0.001), and the upward trend was statistically significant in both. The AAPC of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 5.37% (t = 5.26, P = 0.002), 5.22% (t = 5.66, P = 0.001), 7.20% (t = 6.88, P < 0.001), 10.00% (t = 12.58, P < 0.001), 9.96% (t = 7.34, P < 0.001) and 8.83% (t = 3.51, P = 0.013), and the upward trend was statistically significant. Conclusion: The overall survival rate of registered cases of liver cancer in the Qidong region's entire population has greatly improved, but there is still much room for improvement. Hence, constant attention should be paid to the study on preventing and treating liver cancer.

Abstract
Detecting the early signs of stroke using non-contrast computerized tomography (NCCT) is essential for the diagnosis of acute ischemic stroke (AIS). However, the hypoattenuation in NCCT is difficult to precisely identify, and accurate assessments of the Alberta Stroke Program Early CT Score (ASPECTS) are usually time-consuming and require experienced neuroradiologists. To this end, this study proposes DGA3-Net, a convolutional neural network (CNN)-based model for ASPECTS assessment via detecting early ischemic changes in ASPECTS regions. DGA3-Net is based on a novel parameter-efficient dihedral group CNN encoder to exploit the rotation and reflection symmetry of convolution kernels. The bounding volume of each ASPECTS region is extracted from the encoded feature, and an attention-guided slice aggregation module is used to aggregate features from all slices. An asymmetry-aware classifier is then used to predict stroke presence via comparison between ASPECTS regions from the left and right hemispheres. Pre-treatment NCCTs of suspected AIS patients were collected retrospectively, which consists of a primary dataset (n = 170) and an external validation dataset (n = 90), with expert consensus ASPECTS readings as ground truth. DGA3-Net outperformed two expert neuroradiologists in regional stroke identification (F1 = 0.69) and ASPECTS evaluation (Cohen's weighted Kappa = 0.70). Our ablation study also validated the efficacy of the proposed model design. In addition, class-relevant areas highlighted by visualization techniques corresponded highly with various well-established qualitative imaging signs, further validating the learned representation. This study demonstrates the potential of deep learning techniques for timely and accurate AIS diagnosis from NCCT, which could substantially improve the quality of treatment for AIS patients.

Abstract
Objective: To construct a diagnostic model of schizophrenia (SCZ) based on biomarkers such as serum neurotrophic factor. Methods: Patients of schizophrenia (SCZ group) and healthy controls (HC group) who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2019 were prospectively selected. In the SCZ group, the mental symptoms were assessed by the positive and negative symptom scale (PANSS), cognitive function was assessed by the MATRICS consensus cognitive battery (MCCB), brain-derived neurotrophic factor (BDNF), glial cell derived neurotrophic factor (GDNF), fasting glucose (FGB) and fasting insulin (FINS) levels were detected, and insulin resistance (HOMA-IR) was calculated. The same methods were used to evaluate cognitive function, measure BDNF, GDNF, FGB and FINS levels, and calculate HOMA-IR in HC group. The indexes with statistically significant differences between the two groups were selected to be included in the model. The diagnostic model was constructed by machine learning and verified by cross-validation method, the receiver operating curve (ROC) was plotted, and the area under the curve (AUC), sensitivity and specificity were calculated. Results: (1) A total of 142 patients (70 males and 72 females) with schizophrenia were finally included, and aged (25±4) years. Meanwhile, 140 healthy controls (72 males and 68 females) were also enrolled, and aged (26±4) years. In SCZ group, scores in all areas of cognitive function were lower than those in HC group (all P<0.001), the levels of serum BDNF and GDNF [(6.7±1.8) ng/ml and (405±93) pg/ml] were also lower than those in HC group [(12.3±3.2) ng/ml and (574±139) pg/ml] (both P<0.001), but the levels of FINS and HOMA-IR [(8.4±0.8) μU/ml and 1.7±0.3] were higher than those in HC group [(6.7±0.9) μU/ml and 1.4±0.3] (both P<0.001). (2) Correlation analysis showed that the level of serum BDNF had a negative correlation with negative symptom scores and total scores (r=-0.31, P<0.001; r=-0.17, P=0.040), but had a positive correlation with attention/alertness (CPT-IP) T scores, working memory (WSM-Ⅲ) T scores and visual learning (BVMT) T scores in SCZ group (r=0.39, 0.37 and 0.29, all P<0.001). The level of serum GDNF also had a positive correlation with CPT-IP T scores, WSM-Ⅲ T scores and BVMT T scores (r=0.32, P<0.001; r=0.23, P=0.007; r=0.40, P<0.001). The values of HOMA-IR had a positive correlation with social cognition (MSCEIT) T scores in SCZ group (r=0.18, P=0.033). (3) AUC of the early diagnosis model constructed by combining BDNF, GDNF and HOMA-IR was 0.890 (95%CI: 0.832-0.940), the accuracy was 0.89, the sensitivity and specificity was 0.94 and 0.82, respectively. Conclusion: The final diagnostic model based on biomarkers of serum neurotrophic factor has good diagnostic efficiency for SCZ, but large-scale independent sample verification is still needed.

Abstract
Pulmonary rehabilitation can relieve dyspnea in patients, improve their healthy status and exercise tolerance. It is the most cost-effective comprehensive intervention. Although the role of pulmonary rehabilitation has been recognized and recommended in clinical guidelines, it is still underutilized worldwide. Therefore, how to improve the knowledge and awareness of pulmonary rehabilitation and to increase accessibility, thus promoting its application and completion, is the key point of clinical research. Related research has also made a series of important progress. This review summarized the latest research findings from September 2021 to October 2022, with the goal of increasing healthcare professionals' knowledge and awareness in order to improve patient referral to pulmonary rehabilitation.

Abstract
Objective: The survival of colorectal cancer in Qidong City, Jiangsu Province from 1972 to 2016 was analyzed to provide a basis for the evaluation of prognosis and the formulation of prevention and control measures. Methods: Colorectal cancer data were obtained from the Qidong Cancer Registration and Reporting System, and the follow-up was up to December 31, 2021. The observed survival rate (OSR) and relative survival rate (RSR) were calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival, and the ARIMA model was used to predict the trend of colorectal cancer survival. Results: There were 8 637 new cases of colorectal cancer in Qidong from 1972 to 2016. Dividing 1972-2016 into 9 periods at 5-year intervals, the 5-year OSR from 1972-1976 to 2012-2016 increased from 21.86% to 48.86%, and the 5-year RSR increased from 26.45% to 59.91%. The increasing trend of RSR was statistically significant (χ(2)=587.47, P<0.001). From 1972 to 2016, the survival rates of colorectal cancer in different sexes in Qidong were similar, and the 5-year RSR was 44.63% for men and 44.07% for women. Since the 1990s, the 5-year OSR and RSR for men have been lower than those for women. From 1972 to 2016, the 5-year RSR of colorectal cancer in Qidong was significantly improved in the 65-74 and ≥75-year-old groups, but the survival rate of the ≥75-year-old group was still the lowest (36.78%), followed by the 35-44-year-old group ( 43.04%). The time trend showed that the overall AAPC of colorectal cancer 5-year RSR in Qidong from 1972 to 2016 was 2.50% (t=16.45, P<0.001). The upward trend of different sexes was consistent, and the increase was greater in women (AAPC for males=2.18%, AAPC for females=2.54%, both P<0.05). The 5-year RSR of colorectal cancer in each age group showed an upward trend, and the AAPCs of the 35-44, 45-54, 55-64, 65-74, and ≥75-year-old groups were 1.54%, 1.83%, 2.00%, 3.51% and 4.35%, respectively (all P<0.05). The prediction results of colorectal cancer survival rate showed that the 5-year RSR of colorectal cancer in Qidong will increase to 71.62% by 2026. Conclusions: The overall survival rate of colorectal cancer patients in Qidong has been greatly improved, but there is still room for improvement. We should continue to pay attention to the early diagnosis and early treatment of colorectal cancer.

Abstract
Objective: The survival rate of gastric cancer cases in the whole population of Qidong City of Jiangsu Province from 1972 to 2016 was analyzed to provide a data basis for prevention and control of gastric cancer. Methods: The observed survival rate (OSR) was calculated by the life table method, the relative survival rate (RSR) was calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. Age-standardized relative survival rate (ARSR) was calculated using the International Cancer Survival Standard (ICSS). The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival rate, and the trend analysis of the overall survival rate of gastric cancer and the survival rates of different sexes and ages was conducted. The ARIMA model was used to predict the survival rate. Results: From 1972 to 2016, there were 18 067 new cases of gastric cancer in Qidong City. The OSRs at 1, 5, and 10 years were 37.12%, 17.16%, and 12.86%, respectively, and the RSRs at 1, 5, and 10 years were 38.83%, 21.73%, and 21.20%. Dividing 1972-2016 into 9 periods at 5-year intervals, compared with 1972-1976, the 5-year RSR in 2012-2016 increased from 12.53% to 36.26%, and the RSR in the 9 periods increased with statistical significance (χ(2)=747.19, P<0.001). Both OSR and RSR were slightly higher in men than in women, and decreased with age. The AAPC results showed that the AAPC of the 5-year RSR of gastric cancer in Qidong was 2.88%, 2.75% in males and 3.05% in females, and the upward trend was statistically significant (P<0.001). From 1972 to 2016, the 5-year RSR of gastric cancer in all age groups showed an upward trend. Except for the 35-44-year-old group (AAPC=1.07%, t=2.16, P=0.067), the age groups had statistical significance ( AAPC=2.59% in the 45-54-year-old group, AAPC=3.19% in the AAPCs of other 55-64-year-old group, AAPC=3.99% in the 65-74-year-old group, and AAPC=2.97% in the 75-year-old group, all P<0.05). The prediction results of the ARIMA model showed that in 2026, the 5-year OSR of gastric cancer in Qidong will increase to 39.82%, and the 5-year RSR will increase to 49.23%. Conclusion: The overall survival rate of registered gastric cancer cases in Qidong has been greatly improved, but there is still large room for improvement. More attention should be paid to the prevention and treatment of gastric cancer.

Abstract
Objective: To analyze the survival of esophageal cancer cases in Qidong, Jiangsu Province from 1972 to 2016, and provide a basis for the prognosis evaluation and prevention of esophageal cancer patients. Methods: The data of esophageal cancer were obtained from the Qidong Cancer Registration and Reporting System, and the follow-up date ended December 31, 2021. Observed survival rate (OSR) and relative survival rate (RSR) were calculated by SURV 3.01 software, and Hakulinen's likelihood ratio test was used for statistical difference comparison. Joinpoint regression model was used to conduct the average annual percentage change (AAPC) in esophageal cancer survival rate, and the ARIMA model was used to predict the trend of esophageal cancer survival rate. Results: During 1972 to 2016, there were 5 112 new cases of esophageal cancer in Qidong. The OSR of esophageal cancer at 1, 5 and 10 years were 24.43%, 6.93% and 4.43%, and the RSR at 1, 5 and 10 years were 25.88%, 9.35% and 8.34%, respectively. Dividing 1972-2016 into 9 periods, compared with 1972-1976, the 5-year RSR from 2012-2016 increased from 4.47% to 17.85%, and the RSR trend of the 9 periods was statistically significant (χ(2)=263.43, P<0.001). The survival rate of female with esophageal cancer was slightly higher than that of male, however, there was no significant difference in RSR between male and female (χ(2)=9.40, P=0.401). The 5-OSR and 5-RSR for male were 6.73% and 9.11%, and for female were 7.37% and 9.87%, respectively. The 5-RSR for the age groups of 45-54, 55-64, 65-74, and over 75 years old were 11.99%, 11.21%, 8.17% and 7.08%, respectively. There was a statistically significant difference in RSR among different age groups (χ(2)=98.19, P<0.001). The time trend results showed that the overall AAPC of the 5-RSR of esophageal cancer in Qidong from 1972 to 2016 was 3.89% (t=11.98, P<0.001). The 5-RSR uptrend was consistent among different genders, and the uptrend was greater in female (AAPC=4.25% for male, and AAPC=5.72% for female, P<0.05). Furthermore, the 5-RSR of esophageal cancer in all age groups showed an upward trend, and the upward trend was statistically significant in the 55-64-year-old group (AAPC=4.23%, P<0.05) and the 65-74-year-old group (AAPC=6.82%, P<0.05), there was no statistical significance in the 45-54-year-old group (AAPC=2.17%, P>0.05) and more than 75 years old group (AAPC=1.82%, P>0.05). Survival rate prediction of esophageal cancer showed that by 2026, 5-RSR will increase to 24.79%. Conclusions: During 1972 to 2016, the overall survival rate of esophageal cancer in the whole population of Qidong has improved to a certain extent, but there is still a large room for improvement. More emphasis should be continued to strengthen on the early diagnosis and early treatment of esophageal cancer.

Abstract
Objective: To describe the epidemic characteristics of esophageal cancer mortality in Qidong from 1972 to 2016, and to provide baseline for making control measures and strategies for prevention. Methods: The cancer registry data were collected and analyzed on mortality of oesophagus cancer during 1972-2016 in Qidong in different sex, age and time. Indices of statistics included crude mortality rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), 35-64 years truncated rate, 0-74 years cumulative rate, cumulative risk, average annual percentage change (AAPC), mortality by period and mortality in the birth cohort. Results: A total of 4 795 esophageal cancer cases (male: 3 315, female: 1 480) died during the 45 years, accounting for 4.85% of all cancer deaths. The crude mortality was 9.48/10(5) (CASR: 3.62/10(5,) WASR: 6.30/10(5)) from 1972 to 2016. The crude mortality was significantly increased with age. In 2016, the crude mortality was 11.61/10(5) (CASR: 2.64/10(5,) WASR: 4.89/10(5)), respectively. The average annual percentage change (AAPC) were 0.99%、-2.03%、-1.72%. The mortalities of esophageal cancer in all age groups from 35 to 74 have been decreasing since the 1980s. The age-birth cohort analysis showed a decline in mortality rates in age groups from 40 to 79. Conclusions: The crude mortality rate of esophageal cancer increases slightly in Qidong, while the China age-standardized rate and world age-standardized rate decrease significantly. However, esophageal cancer is still one of the malignant tumors that affects the health of residents and seriously threatens the people's lives and health. The situation of cancer prevention and control is still serious in Qidong.

Abstract
A new AAPH-Incubating HPLC-DAD-HR MS/MS method was developed for the rapid and high-throughput screening of antioxidants directly in natural products and applied to Gardenia jasminoides fruit. This method was assumed that the peak areas of compounds with potential antioxidant activity in HPLC chromatograms would be significantly reduced or disappeared after incubating with the AAPH which can release ROO at physiological conditions (37 °C, pH 7.4). Additionally, the activity of antioxidants can be evaluated by comparing the peak reduction rates and the screened components can be further identified by HRMS/MS. Then, 17 potential natural antioxidants from the crude extract of GJF was screened. Among them, three major components including crocin I, crocin II and crocetin showed excellent ROO scavenging activity, which were further validated by the ORAC assay. In conclusion, our study provided a simple and effective strategy to rapidly screen antioxidants in natural products.

Abstract
Under the pressure of rapid urbanization, the spatiotemporal dynamics of urban green spaces (UGS) have enormous impacts on the local ecological system and environment at different scales. In this study, UGS in Hefei City, which has experienced rapid urbanization from 1995 to 2015, were extracted based on time-series Landsat-5 TM and Landsat-8 OLI images, and different types of parks were mapped based on GF-2 images combined with multi-source metadata. Dynamic patterns of green space were examined by drawing the spatial variations of green space at the city, inner city, and park scales. Results revealed that: (1) At the city level, UGS decreased with the rapid urbanization, especially farmland sharply lost in areas around existing urban areas and along the transportation corridors. (2) At the inner-city level, concentric analyses showed that UGS changes in different rings had unique trends, and the dynamic changes were the most significant in Rings 2 and 3. Comparative analysis of old and new districts showed that the common characteristics of UGS changes were the transfer-out of farmland and the transfer-in of built-up land, and the newer the region, the more intense the changes. (3) At the park level, the number and area of urban parks were increasing from the center to the periphery, and the type of park gradually changed from single to rich. Significant spatial heterogeneity was identified in the landscape patterns of urban parks based on fishnet cell analysis. It is fundamental to assign urban construction land for socio-economic development, while planning UGS at different scales; moreover, integrating different green space-related policies could protect the UGS and maintain its stability. Only in this way can UGS combine economic, social, and ecological benefits under the background of rapid urbanization.

Abstract
OBJECTIVE To evaluate the use of 3-D printed models as compared to didactic lectures in the teaching of acetabular fractures for Orthopaedic trainees. METHODS This was a randomised prospective study conducted in a tertiary hospital setting which consisted of 16 Orthopaedic residents. Ten different cases of acetabular fracture patterns were identified and printed as 3-D models. The baseline knowledge of orthopaedic residents regarding acetabular fracture classification and surgical approach was determined by an x-ray based pre-test. Trainees were then randomly assigned into two groups. Group I received only lectures. Group II were additionally provided with 3-D printed models during the lecture. Participants were then assessed for comprehension and retention of teaching. RESULTS Sixteen trainees participated in the trial. Both Group 1 and 2 improved post teaching with a mean score of 2.5 and 1.9 to 4.4 and 6 out of 10 respectively. The post test score for fracture classification and surgical approach were significantly higher for 3-D model group (p < 0.05). Trainees felt that the physical characteristics of the 3-D models were a good representation of acetabular fracture configuration, and should be used routinely for teaching and surgical planning. CONCLUSION 3-D printed model of real clinical cases have significant educational impact compared to lecture-based learning towards improving young trainees' understanding of complex acetabular fractures.

Abstract
Purpose: Retinopathy screening via digital imaging is promising for early detection and timely treatment, and tracking retinopathic abnormality over time can help to reveal the risk of disease progression. We developed an innovative physician-oriented artificial intelligence-facilitating diagnosis aid system for retinal diseases for screening multiple retinopathies and monitoring the regions of potential abnormality over time. Approach: Our dataset contains 4908 fundus images from 304 eyes with image-level annotations, including diabetic retinopathy, age-related macular degeneration, cellophane maculopathy, pathological myopia, and healthy control (HC). The screening model utilized a VGG-based feature extractor and multiple-binary convolutional neural network-based classifiers. Images in time series were aligned via affine transforms estimated through speeded-up robust features. Heatmaps of retinopathy were generated from the feature extractor using gradient-weighted class activation mapping++, and individual candidate retinopathy sites were identified from the heatmaps using clustering algorithm. Nested cross-validation with a train-to-test split of 80% to 20% was used to evaluate the performance of the screening model. Results: Our screening model achieved 99% accuracy, 93% sensitivity, and 97% specificity in discriminating between patients with retinopathy and HCs. For discriminating between types of retinopathy, our model achieved an averaged performance of 80% accuracy, 78% sensitivity, 94% specificity, 79% F1-score, and Cohen's kappa coefficient of 0.70. Moreover, visualization results were also shown to provide reasonable candidate sites of retinopathy. Conclusions: Our results demonstrated the capability of the proposed model for extracting diagnostic information of the abnormality and lesion locations, which allows clinicians to focus on patient-centered treatment and untangles the pathological plausibility hidden in deep learning models.

Abstract
Major depressive disorder (MDD) and bipolar disorder (BD) are two major mood disorders with partly overlapped symptoms but different treatments. However, their misdiagnosis and mistreatment are common based on the DSM-V criteria, lacking objective and quantitative indicators. This study aimed to develop a novel approach that accurately classifies MDD and BD based on their resting-state magnetoencephalography (MEG) signals during euthymic phases. A revisited 3D CNN model, Semi-CNN, that could automatically detect brainwave patterns in spatial, temporal, and frequency domains was implemented to classify wavelet-transformed MEG signals of normal controls and MDD and BD patients. The model achieved a test accuracy of 96.05% and an average of 95.71% accuracy for 5-fold cross-validation. Furthermore, saliency maps of the model were estimated using Grad-CAM++ to visualize the proposed classification model and highlight disease-specific brain regions and frequencies. Clinical Relevance - Our model provides a stable pipeline that accurately classifies MDD, BD, and healthy individuals based on resting-state MEG signals during the euthymic phases, opening the potential for quantitative and accurate brain-based diagnosis for the highly misdiagnosed MDD/BD patients.

Abstract
Euphorbiaceae, a family of plants mainly grown in the tropics and subtropics, is also widely distributed all over the world and is well known for being rich in rubber, oil, medicinal materials, starch, wood and other economically important plant products. Glutathione S-transferases (GSTs) constitute a family of proteins encoded by a large supergene family and are widely expressed in animals, bacteria, fungi and plants, but with few reports of them in Euphorbiaceae plants. These proteins participate in and regulate the detoxification and oxidative stress response of heterogeneous organisms, resistance to stress, growth and development, signal transduction and other related processes. In this study, we identified and analyzed the whole genomes of four species of Euphorbiaceae, namely Ricinus communis, Jatropha curcas, Hevea brasiliensis, and Manihot esculenta, which have high economic and practical value. A total of 244 GST genes were identified. Based on their sequence characteristics and conserved domain types, the GST supergene family in Euphorbiaceae was classified into 10 subfamilies. The GST supergene families of Euphorbiaceae and Arabidopsis have been found to be highly conserved in evolution, and tandem repeats and translocations in these genes have made the greatest contributions to gene amplification here and have experienced strong purification selection. An evolutionary analysis showed that Euphorbiaceae GST genes have also evolved into new subtribes (GSTO, EF1BG, MAPEG), which may play a specific role in Euphorbiaceae. An analysis of expression patterns of the GST supergene family in Euphorbiaceae revealed the functions of these GSTs in different tissues, including resistance to stress and participation in herbicide detoxification. In addition, an interaction analysis was performed to determine the GST gene regulatory mechanism. The results of this study have laid a foundation for further analysis of the functions of the GST supergene family in Euphorbiaceae, especially in stress and herbicide detoxification. The results have also provided new ideas for the study of the regulatory mechanism of the GST supergene family, and have provided a reference for follow-up genetics and breeding work.

Abstract
PURPOSE Non-contrast computed tomography (NCCT) is a first-line imaging technique for determining treatment options for acute ischemic stroke (AIS). However, its poor contrast and signal-to-noise ratio limit the diagnosis accuracy for radiologists, and automated AIS lesion segmentation using NCCT also remains a challenge. In this paper, we propose R2U-RNet, a novel model for AIS lesion segmentation using NCCT. METHODS We used an in-house retrospective NCCT dataset with 261 AIS patients with manual lesion segmentation using follow-up diffusion-weighted images. R2U-RNet is based on an R2U-Net backbone with a novel residual refinement unit. Each input image contains two image channels from separate preprocessing procedures. The proposed model incorporates multiscale focal loss to mitigate the class imbalance problem and to leverage the importance of different levels of details. A proposed noisy-label training scheme is utilized to account for uncertainties in the manual annotations. RESULTS The proposed model outperformed several iconic segmentation models in AIS lesion segmentation using NCCT, and our ablation study demonstrated the efficacy of the proposed model. Statistical analysis of segmentation performance revealed significant effects of regional stroke occurrence and side of the stroke, suggesting the importance of region-specific information for automated segmentation, and the potential influence of the hemispheric difference in clinical data. CONCLUSION This study demonstrated the potentials of R2U-RNet model for automated NCCT AIS lesion segmentation. The proposed model can serve as a tool for accelerating AIS diagnoses and improving the treatment quality of AIS patients.

Abstract
Objective: To describe the epidemic characteristics of stomach cancer mortality in Qidong between 1972 and 2016. Methods: The cancer registry data of stomach cancer death and population during 1972-2016 in Qidong was collected. The mortality of crude rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), 35-64 years truncated rate, 0-74 years cumulative rate, cumulative risk, percentage change (PC), annual percent change (APC) were calculated. Results: During 1972-2016, a total of 15 863 (male: 10 114, female: 5 749) deaths occurred attributed to stomach cancer, accounting for 16.04% of all cancers, with CR of 31.37/100 000 (CASR: 12.97/100 000, WASR: 21.39/100 000). The truncated rate of 35-64, cumulative rate of 0-74, and cumulative risk were 28.86/100 000, 2.54%, and 2.51%, respectively. For male, the CR, CASR, WASR were 40.53/100 000, 17.98/100 000, 30.13/100 000, respectively, and for female, the CR, CASR, WASR were 22.45/100 000, 8.52/100 000, 13.92/100 000, respectively. Age-specific mortality analysis showed that the mortality of each age group under 25-year-old group was less than 1/100 000. The CR increased with age. The 50-year-old group reached and exceeded the average mortality of the population, and more than 80-year-old group reached the peak of death. During 1972-2016 in Qidong, The PCs in CR, CASR, and WASR of stomach cancer were 55.43%, -52.02%, -43.60%. The APC were 0.54%, -2.30%, -2.08%, respectively. Period mortality analysis showed that except for the 75-year-old group, the mortality of stomach cancer decreased significantly. Conclusions: The crude mortality of stomach cancer increases slightly in Qidong, while the CASR and WASR decrease significantly. However, stomach cancer is still one of the malignant tumors that most affect health and seriously threat lives.

Abstract
Objective: To describe the trend of upper gastrointestinal cancer mortality in Qidong between 1972 and 2016, and to provide guidelines for prevention and control measures and strategies. Methods: The upper gastrointestinal data was collected in Qidong cancer registration from 1972 to 2016. Crude mortality rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), truncated rate (35-64 years old), cumulative rate (0-74 years old) and cumulative risk were calculated. Annual percent change (APC) was calculated by Joinpoint software. Age-period-cohort model was used to analyze the influence of age, period and birth cohort on the changes in the mortality trend of upper gastrointestinal cancer patients. Results: From 1972 to 2016, there were 20 658 deaths of upper gastrointestinal cancer in Qidong, accounting for 20.89% of all cancer deaths. The CR, CASR, WASR, truncated rate (35-64 years old), cumulative rate (0-74 years old) and cumulative risk were 40.85/100 000, 27.96/100 000, 27.69/100 000, 36.01/100 000, 3.30% and 3.25%, respectively. There were 13 429 male deaths, the CR, CASR, and the WASR were 53.81/100 000, 37.62/100 000, and 39.93/100 000; the female deaths were 7 229, and the CR, CASR, and WASR were 28.23/100 000, 18.87/100 000, 17.25/100 000, respectively. The APCs of the 45-year-old, 55-year-old and 65-year-old age groups were -2.94% (95% CI: -3.32%, -2.56%), -2.94% (95% CI: -3.22%, -2.66%) and -2.04% (95% CI: -2.39%, -1.69%), with significant difference (P<0.05), while without significance of 75-year-old group (P>0.05). From 1972 to 2016, the APCs of CR, CASR, and WASR in the gastrointestinal cancer were 0.65% (95%CI: 0.43%, 0.87%), -2.01% (95%CI: -2.24%, -1.77%) and -2.05% (95%CI: -2.28%, -1.81%). The age-period-cohort model showed that the mortality of upper gastrointestinal cancer was increased with age (P<0.05). Conclusions: The crude mortality of upper gastrointestinal cancer increases slightly in Qidong, while the CASR and WASR decrease significantly. However, with aged tendency of population, the early diagnosis and treatment of upper gastrointestinal cancer is still needed to be paid attention.

Abstract
To assess the positive predictive value (PPV) of extended noninvasive prenatal testing (NIPT-plus) for fetal chromosomal abnormalities. This retrospective research enrolled 511 cases of pregnant women with positive NIPT-plus results at the Obstetrics and Gynecology Hospital of Fudan University from May 2017 to January 2021. Karyotype analysis and chromosome microarray analysis (CMA) techniques was applied for verification. All cases were followed to determine their pregnancy outcome. The Chi-square test was used in PPV. 63 out of 511 refused prenatal diagnosis after counseling, 448 pregnant women with prenatal diagnosis showed that the PPVs of NIPT-plus test for fetal trisomy 21, 18 and 13 (T21, T18, T13), sex chromosome aneuploidy (SCAs) and chromosome microdeletion/microduplication syndrome (MMS) were 86.0% (92/107), 79.5% (35/44), 54.5% (12/22), 39.5% (75/190), and 41.7% (30/72), respectively. The results revealed that the PPV was higher among older pregnant women compared to young pregnant women (77.8% vs. 51.9%,P<0.01). With increasing maternal age, the PPV of NIPT-plus presented increasing trends for T21, T13, and composite PPV except for T18 or SCAs. In addition, the termination rates for confirmed SCAs fetal karyotypes 45, X; 47, XXX; 47, XXY and 47, XYY were 11/11, 3/15, 91.7% (22/24) and 1/14, respectively. NIPT-plus can safely and effectively detect fetal chromosomal abnormalities and can be extended to MMS screening, significantly reducing the proportion of interventional prenatal diagnoses, and those with positive screening still require further confirmation.

Abstract
Lutein was enzymatically acylated with saturated fatty acid vinyl esters of different lengths of carbon chain (C6 -C14 ) under the action of Candida antarctica lipase B (Novozyme 435). The acylation reaction was optimized by considering substrate molar ratio, reaction solvent, type of enzyme, and reaction time. The highest yield (88%) was obtained using the Novozyme 435 to catalyze the acylation reaction of lutein and vinyl decanoate (lutein/vinyl decanoate molar ratio of 1/10) for 16 h in methyl tert-butyl ether. Ten lutein esters were synthesized, isolated, and purified, which were characterized by Fourier-transform infrared spectroscopy, high-resolution mass spectrometry, and nuclear magnetic resonance spectroscopy. We found that the acylation of lutein improved its antioxidant capacity in lipid system and thermal stability. Our study extended the potential application of lutein in lipophilic food, cosmetic, and pharmaceutical industries. Practical Application: Enzyme acylation of lutein improved its antioxidant capacity in lipid system and thermal stability, extended its potential application in food, cosmetic, and pharmaceutical industries. In addition, our study also provided a new perspective and cognition for the further development and utilization of lutein.

Abstract
Objective: To identify gene variants and investigate clinical features of nonmuscle myosin heavy chain 9-related disease (MYH9-RD). Methods: In this retrospective study, the data of patients with MYH9-RD admitted to Shenzhen Children's Hospital from July 2017 to September 2020 were extracted. The gene variants, clinical features and laboratory tests results were summarized. Results: Among the 6 children, 4 were males and 2 were females, aged 4.0 (0.5-7.6) years. Main clinical manifestations included thrombocytopenia (6 cases), epistaxis (3 cases), petechias (2 cases), traumatic hematoma (1 case), and abnormal liver enzymes (1 case). One patient had no family history, and the other 5 cases were pedigrees. Two pedigrees (2 cases) had long-term microscopic hematuria, one pedigree (2 cases) had history of early cataract, and three pedigrees (5 cases) had chronic mild elevation of liver enzymes. Four MYH9 gene variants were found in 12 patients, including c.2104C>T(p.R702C) in exon 17, c.4270G>A(p.D1424N) in exon 31, c.5521G>A (p.E1841K) in exon 39, and c.5797C>T (p.R1933X) in exon 41. According to the family pedigrees analysis, except for the case of variant in exon 17 which was spontaneous mutation with no family history, the other variants were from their father or mother. The complete blood count results showed a decreased platelet number in these patients, and the counting results of the automated hematology analyzer were significantly lower than that of manual counting method ((33.4±17.2) × 10⁹ vs. (60.4±21.0) × 109/L,t=-5.83, P<0.05). The examination of the peripheral blood smear revealed the presence of thrombocytopenia with giant platelets and granulocyte inclusion bodies. The MYH9 gene variant (R702C) located at the N-terminus head domain of non-muscle myosin heavy chain ⅡA (NMMHC-ⅡA), which has ATPase activity, led to severe reduction of platelet number (<20×109/L) and obscure granulocyte inclusion bodies. However, higher platelet numbers (40×109-80×109/L) and obvious granulocyte inclusion bodies were observed in patients with tail-position mutations at C-terminus. Conclusions: The clinical phenotypes of MYH9-RD were variable. The mutations in certain regions of MYH9 gene were related to platelet count and granulocyte inclusion bodies. MYH9-RD should be considered in individuals with unknown etiology and persistent thrombocytopenia which is non-responsive to conventional treatment, regardless of family history. Complete blood count and blood smear morphology examinations are the first steps to screen and diagnose the disease. The laboratory should pay attention to the morphological review rules and standardized reports.

Abstract
Ocean currents play a significant role in driving the long-distance dispersal (LDD), spatial distribution and phylogeographic patterns of many organisms. Integrating phylogeographic analyses and mechanistic ocean current modelling can provide novel insights into the evolutionary history of terrestrial littoral species but has been rarely applied in this context. We focused on a group of Cycas that have buoyant seeds and occupy coastal habitats. By integrating evidence from mechanistic simulations and whole plastomic data, we examined the role of ocean circulation in shaping the phylogeography of these Cycas species. Plastomes of the studied Cycas species showed extreme conservatism, following a post-Pleistocene divergence. Phylogenies revealed three subclades, corresponding to the Pacific Ocean, Sunda Shelf and Indian Ocean. The ocean modelling results indicate that hotspots of seed stranding coincide well with the contemporary distribution of the Cycas species and that drifting trajectories from the three subclades are largely confined to separate regions. These findings suggest that ocean current systems, by driving long-distance dispersal, have shaped the distribution and phylogeography for Cycas with buoyant seeds. This study highlights how the combination of genomic data and ocean drift modelling can help explain phylogeographic patterns and diversity in terrestrial littoral ecosystems.

Abstract
Background and Aims To explore the long-term trend of liver cancer survival, based on the real-world data (RWD) in the past 45 years from a population-based cancer registry, in Qidong, China. Methods A number of 32,556 patients with liver cancer were registered during the period of 1972 to 2016. Mixed methods by active and passive follow-up were performed. Life table method was employed for survival analysis by SPSS22 software. Wilcoxon (Gehan) statistics was considered as a significant test. Relative survival was calculated by using SURV software, and its annual percent change (APC) was estimated by the Joinpoint Regression Program. Results The overall observed survival (OS) rates of 1-, 5-, 10-, and 20-year rates from the data series were 18.51%, 6.28%, 4.03%, and 2.84%, and their relative survival (RS) rates were 18.88%, 6.95%, 4.96%, and 4.49%, respectively. For 24,338 male cases, the 5-year OS and RS rates were 5.93% and 6.54%, and for 8218 female cases, 7.34% and 8.15%, respectively, with P values less than 0.01. Survival rates of liver cancer from three 15-year periods of 1972-1986, 1987-2001, and 2002-2016 have increased significantly, with 5-year OS rates of 2.02%, 4.40%, and 10.76%, 5-year RS rates of 2.18%, 4.83%, and 12.18%; 10-year OS and RS rates of 0.95%, 3.00%, and 7.02%, vs 1.13%, 3.65%, and 8.96%, respectively, showing a very significant upward trend (P<0.01). There are significant differences among age groups (P<0.01): those aged 55-64 demonstrated the best OS and RS rates of 5-year, being 8.44% and 9.09%, respectively. Conclusion There are significant gender and age differences in the survival rate of liver cancer in Qidong. RWD indicates the relative lower survival rate of liver cancer in this area, but great improvement has been achieved over the past decades.

Abstract
Objective: To explore the consistency of peripheral whole blood and venous serum procalcitonin (PCT) levels, and the value of peripheral whole blood PCT in evaluating pediatric bacterial infection. Methods: This multicenter cross-sectional parallel control study was conducted in 11 children's hospital. All the 1 898 patients older than 28 days admitted to these hospitals from March 2018 to February 2019 had their peripheral whole blood and venous serum PCT detected simultaneously with unified equipment, reagent and method. According to the venous serum PCT level, the patients were stratified to subgroups. Analysis of variance and chi-square test were used to compare the demographic characteristics among groups. And the correlation between the peripheral blood and venous serum PCT level was investigated by quantitative Pearson correlation analysis.The PCT resultes were also converted into ranked data to further test the consistency between the two sampling methods by Spearman's rank correlation test. Furthermore, the ranked data were converted into binary data to evaluate the consistency and investigate the best cut-off of peripheral blood PCT level in predicting bacterial infection. Results: A total of 1 898 valid samples were included (1 098 males, 800 females),age 27.4(12.2,56.7) months. There was a good correlation between PCT values of peripheral whole blood and venous serum (r=0.97, P<0.01). The linear regression equation was PCTvenous serum=0.135+0.929×PCTperipheral whole blood. However, when stratified to 5 levels, PCT results showed diverse and unsatisfied consistency between the two sampling methods (r=0.51-0.92, all P<0.01). But after PCT was converted to ordinal categorical variables, the stratified analysis showed that the coincidence rate of the measured values by the two sampling methods in each boundary area was 84.9%-97.1%. The dichotomous variables also showed a good consistency (coincidence rate 96.8%-99.3%, Youden index 0.82-0.89). According to the severity of disease, the serum PCT value was classified into 4 intervals(<0.5、0.5-<2.0、2.0-<10.0、≥10.0 μg/L), and the peripheral blood PCT value also showed a good predictive value (AUC value was 0.991 2-0.997 9). The optimal cut points of peripheral whole blood PCT value 0.5、1.0、2.0、10.0 μg/L corresponding to venous serum PCT values were 0.395, 0.595, 1.175 and 3.545 μg/L, respectively. Conclusions: There is a good correlation between peripheral whole blood PCT value and the venous serum PCT value, which means that the peripheral whole blood PCT could facilitate the identification of infection and clinical severity. Besides, the sampling of peripheral whole blood is simple and easy to repeat.

Abstract
Objective. Neural communication or the interactions of brain regions play a key role in the formation of functional neural networks. A type of neural communication can be measured in the form of phase-amplitude coupling (PAC), which is the coupling between the phase of low-frequency oscillations and the amplitude of high-frequency oscillations. This paper presents a beamformer-based imaging method, beamformer-based imaging of PAC (BIPAC), to quantify the strength of PAC between a seed region and other brain regions.Approach. A dipole is used to model the ensemble of neural activity within a group of nearby neurons and represents a mixture of multiple source components of cortical activity. From ensemble activity at each brain location, the source component with the strongest coupling to the seed activity is extracted, while unrelated components are suppressed to enhance the sensitivity of coupled-source estimation.Main results. In evaluations using simulation data sets, BIPAC proved advantageous with regard to estimation accuracy in source localization, orientation, and coupling strength. BIPAC was also applied to the analysis of magnetoencephalographic signals recorded from women with primary dysmenorrhea in an implicit emotional prosody experiment. In response to negative emotional prosody, auditory areas revealed strong PAC with the ventral auditory stream and occipitoparietal areas in the theta-gamma and alpha-gamma bands, which may respectively indicate the recruitment of auditory sensory memory and attention reorientation. Moreover, patients with more severe pain experience appeared to have stronger coupling between auditory areas and temporoparietal regions.Significance. Our findings indicate that the implicit processing of emotional prosody is altered by menstrual pain experience. The proposed BIPAC is feasible and applicable to imaging inter-regional connectivity based on cross-frequency coupling estimates. The experimental results also demonstrate that BIPAC is capable of revealing autonomous brain processing and neurodynamics, which are more subtle than active and attended task-driven processing.

Abstract
Cr5Te8is a half metal with 2D van der Waals ferromagnetic structure and its magnetic properties can be tuned by changing the proportionality of Cr and Te. We report an investigation of magnetization and magnetic anisotropy near the critical transition region of a Cr5-yTe8single crystal with the static and dynamic probes, to unravel the nature of field-dependent spin-spin interactions. The magnetic transition temperatureTCincreasing from 255 K (at near zero-field) to 279 K (at 65 kOe along theab-plane) has been identified. Accordingly, a phase diagram of field versus transition temperature has been established. From the analysis of the field dependence of the critical behavior, we provided evidence that the scenario of 2D Heisenberg-type interactions can be employed to interpret the field-dependent magnetic transitions in Te-rich Cr4.8Te8. The precise picture for the field-reduced spin-spin interaction range has been obtained. The conclusion drawn from the present study demonstrated that Cr4.8Te8is a promising candidate for the spintronic applications with a tunable magnetic transition temperature.

Abstract
OBJECTIVE The association between ABO blood group and risk of liver cancer is unclear, although few studies have reported positive results. This study examined the relationship between ABO blood group and liver cancer in hepatitis B surface antigen (HBsAg)-positive individuals. DESIGN A high-risk population-based cohort study. SETTING The study was started in 2007 and closed in 2019; the number of observed person-years as obtained by ABO blood group. PARTICIPANTS The study included 3663 individuals with positive HBsAg, including men aged 30-70 and women aged 40-70. OUTCOME MEASURES The frequencies of ABO group in the cohort population and patients with liver cancer were calculated, respectively. χ2 test was used to compare differences, and the relative risk (95% CI) for development of liver cancer was evaluated. RESULTS The frequency distribution of blood types A, B, O and AB was 1118 (30.52%), 1073 (29.29%), 1104 (30.14%) and 368 (10.05%), respectively, among 3663 cohort individuals. In the cohort, patients with liver cancer (n=336) were of the following frequencies: type A: 104 (30.95%); type B: 97 (28.87%); type O: 95 (28.27%); and type AB: 40 (11.90%). No significant difference was found between patients with liver cancer and other individuals. The annual incidence rate of liver cancer was 906.34 per 100 000 person-years, and for blood type A, B, O and AB the rates were 917.76, 893.78, 846.02 and 1093.43 per 100 000 person-years, respectively. The relative risk (95% CI) was 0.97 (0.74 to 1.29), 0.92 (0.70 to 1.22) and 1.19 (0.82 to 1.72) for blood types B, O and AB, respectively, compared with blood type A. CONCLUSION There were no significant differences in the frequency distribution of ABO blood groups in patients with liver cancer within this high-risk cohort, which demonstrates lack of positive association between ABO blood group and risk of liver cancer.

Abstract
Purpose Bladder cancer is a common malignant tumor of the urinary system, with the fourth-highest incidence of male malignant tumors in Europe and the United States. So far, the mechanism of bladder cancer progression and metastasis has not been clarified. The aim of our study was to validate the way of long noncoding RNA (lncRNA) KCNMB2-AS1 on the metabolism and growth of bladder cancer cells by miR-3194-3p/SMAD5. Patients and Methods The Gene Expression was analyzed by qRT-PCR in bladder cancer tissues and cell lines, with the highly expressed KCNMB2-AS1 screened out. Cell proliferation was detected by Edu staining and clone formation assay, cell migration, and invasion by wound healing and transwell assays. Cell stemness was determined by assessing sphere-forming ability and stemness marker. Correlation between miRNA and lncRNA/gene was verified by dual‐luciferase assay and RIP, and the effect of KCNMB2-AS1 on bladder cancer growth by nude mice tumor formation experiment. Results Here, we revealed the increased level of KCNMB2-AS1 in bladder cancer for the first time. Knockdown of KCNMB2-AS1 in vitro prevented the ability of proliferation, metastasis, and stemness of cancer cells. In vivo, the silencing of KCNMB2-AS1 also prevented tumor growth in vivo. Next, we revealed that KCNMB2-AS1 could interact with miR-3194-3p and uncovered that SAMD5 was a downstream target of miR-3194-3p. Conclusion In conclusion, KCNMB2-AS1 mediated the bladder cancer cells progress by regulating the miR-3194-3p/SAMD5 signal pathway, which would provide a new target for bladder cancer research.

Abstract
Rutin (3',4',5,7-tetrahydroxy-flavone-3-rutinoside) was enzymatically acylated with benzoic acid and its esters (methyl benzoate and vinyl benzoate) using Thermomyces lanuginosus lipase (Lipozyme TLIM). The acylation reaction was optimized by varying the reaction medium, reaction temperature, acyl donor, substrate molar ratio, and reaction time. The highest conversion yield (76%) was obtained in tert-amyl alcohol (60 °C, 72 hr) using vinyl benzoate (molar ratio of 1:10) as acyl donor. The acylation occurred at the 2'''-OH and 4'''-OH of the rhamnose unit and the 2''-OH position of the glucose moieties. Three novel rutin acylated derivatives (compounds 1-3) were purified and characterized by HR-MS and 1D and 2D NMR spectroscopy. We found that acylation significantly improved lipophilicity, capacity to inhibit lipid peroxidation, anticancer capacity and substantially maintained the antioxidant activity of rutin. This research provides important insights in the acylation of flavonoids with different glycosyl moieties. PRACTICAL APPLICATION: In this study, three novel rutin derivatives were successfully synthesized and the highest conversion yield (76%) was obtained by reacting the rutin and vinyl benzoate at molar ratio of 1:10 in tert-amyl alcohol for 72 hr at 60 °C. Introducing a benzoic acid substituent into rutin molecule significantly improved their lipophilicity and inhibition of lipid peroxidation in lipophilic system. Furthermore, this study demonstrated that acylation significantly improved anticancer capacity and substantially maintained the antioxidant activity.

Abstract
Background The research into the recurrence of cough variant asthma (CVA) in congenital heart disease (CHD) are few in number. The purpose of this study is to investigate the effect of CHD on the risk of the recurrence of CVA. Methods This study was a retrospective cohort study of 489 children with CVA aged between one and 14 years, of whom 67 had CHD complicated with CVA and 134 had CVA without CHD at a ratio of 1:2 according to age, sex and index year. The adjusted hazard ratio (aHR) of CVA recurrence in both the CHD cohort and the non-CHD cohort was determined by multivariate analysis using the Cox proportional hazard regression model. Results Adjusting for CHD classification, Mycoplasma pneumonia (MP) infection and immunoglobulin E (IgE) sensitization, the recurrence hazard of CVA in the complex congenital heart disease (CCHD) group (aHR = 3.281; 95% CI 1.648–6.530; P < 0.01) was significantly higher than that in the simple congenital heart disease group (aHR = 2.555; 95% CI 1.739–3.752; P < 0.01). Further, children with IgE sensitization (aHR = 2.172; 95% CI 1.482–3.184; P < 0.01) had a higher recurrence hazard of CVA than those without IgE sensitization, and children with MP infection (aHR = 1.777; 95% CI 1.188–2.657; P < 0.01) had a higher recurrence hazard of CVA than those without the MP infection. Conclusion The hazard of recurrent CVA is higher in children with CHD, especially in the CCHD children. In addition, those children with IgE sensitization or a MP infection had an increased hazard of recurrent CVA.

Abstract
Background and aims: Liver cancer is one of the most dominant malignant tumors in the world. The trends of liver cancer mortality over the past six decades have been tracked in the epidemic region of Qidong, China. Using epidemiological tools, we explore the dynamic changes in age-standardized rates to characterize important aspects of liver cancer etiology and prevention. Methods Mortality data of liver cancer in Qidong from 1958 to 1971 (death retrospective survey) and from 1972 to 2017 (cancer registration) were tabulated for the crude rate (CR), and age-standardized rate and age-birth cohorts. The average annual percentage change was calculated by the Joinpoint Regression Program. Results The natural death rate during 1958–2017 decreased from 9‰ to 5.4‰ and then increased to 8‰ as the population aged; cancer mortality rates rose continuously from 57/105 to 240/105. Liver cancer mortality increased from 20/105 to 80/105, and then dropped to less than 52/105 in 2017. Liver cancer deaths in 1972–2017 accounted for 30.53% of all cancers, with a CR of 60.48/105, age-standardized rate China (ASRC) of 34.78/105, and ASRW (world) of 45.71/105. Other key features were the CR for males and females of 91.86/105 and 29.92/105, respectively, with a sex ratio of 3.07:1. Period analysis showed that the ASRs for mortality of the age groups under 54 years old had a significant decreasing trend. Importantly, birth cohort analysis showed that the mortality rate of liver cancer in 40–44, 35–39, 30–34, 25–29, 20–24, 15–19 years cohort decreased considerably, but the rates in 70–74, and 75+ increased. Conclusions The crude mortality rate of liver cancer in Qidong has experienced trends from lower to higher levels, and from continued increase at a high plateau to most recently a gradual decline, and a change greatest in younger people. Many years of comprehensive prevention and intervention measures have influenced the decline of the liver cancer epidemic in this area. The reduction of intake levels of aflatoxin might be one of the most significant factors as evidenced by the dramatic decline of exposure biomarkers in this population during the past three decades.

Abstract
This paper proposes the Parallel Residual Bi-Fusion Feature Pyramid Network (PRB-FPN) for fast and accurate single-shot object detection. Feature Pyramid (FP) is widely used in recent visual detection, however the top-down pathway of FP cannot preserve accurate localization due to pooling shifting. The advantage of FP is weakened as deeper backbones with more layers are used. In addition, it cannot keep up accurate detection of both small and large objects at the same time. To address these issues, we propose a new parallel FP structure with bi-directional (top-down and bottom-up) fusion and associated improvements to retain high-quality features for accurate localization. We provide the following design improvements: 1) parallel bifusion FP structure with a bottom-up fusion module (BFM) to detect both small and large objects at once with high accuracy; 2) concatenation and re-organization (CORE) module provides a bottom-up pathway for feature fusion, which leads to the bi-directional fusion FP that can recover lost information from lower-layer feature maps; 3) CORE feature is further purified to retain richer contextual information. Such CORE purification in both top-down and bottom-up pathways can be finished in only a few iterations; 4) adding of a residual design to CORE leads to a new Re-CORE module that enables easy training and integration with a wide range of deeper or lighter backbones. The proposed network achieves state-of-the-art performance on the UAVDT17 and MS COCO datasets.

Abstract
Objective: This study was to systematically update the economic evaluation evidence of colorectal cancer screening in mainland China. Methods: Based on a systematic review published in 2015, we expanded the scope of retrieval database (PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang Data, VIP, CBM) and extended it to December 2018. Focusing on the evidence for nearly 10 years (2009-2018), basic characteristics and main results were extracted. Costs were discounted to 2017 using the consumer price index of medical and health care being provided to the residents, and the ratio of incremental cost-effectiveness ratio (ICER) to per capita GDP in corresponding years were calculated. Results: A total of 12 articles (8 new ones) were included, of which 9 were population-based (all cross-sectional studies) and 3 were model-based. Most of the initial screening age was 40 years (7 articles), and most of the frequency was once in a lifetime (11 articles). Technologies used for primary screening included: questionnaire assessment, immunological fecal occult blood test (iFOBT) and endoscopy. The most commonly used indicator was the cost per colorectal cancer detected, and the median (range) of the 20 screening schemes was 52 307 Chinese Yuan (12 967-3 769 801, n=20). The cost per adenoma detected was 9 220 Yuan (1 859-40 535, n=10). In 3 articles, the cost per life year saved (compared with noscreening) was mentioned and the ratio of ICER to GDP was 0.673 (-0.013-2.459, n=11), which was considered by WHO as "very cost-effective" ; The range of ratios overlapped greatly among different technologies and screening frequencies, but the initial age for screening seemed more cost-effective at the age of 50 years (0.002, -0.013-0.015, n=3), than at the 40 year-olds (0.781, 0.321-2.459, n=8). Conclusions: Results from the population-based studies showed that the cost per adenoma detected was only 1/6 of the cost per colorectal cancer detected, and limited ICER evidence suggested that screening for colorectal cancer was generally cost-effective in Chinese population. Despite the inconclusiveness of the optimal screening technology, the findings suggested that the initial screening might be more cost-effective at older age. No high-level evidence such as randomized controlled trial evaluation was found.

Abstract
Abstract Objective To establish a method to identify unknown samples based on combined use of gas chromatography-mass spectrometry (GC-MS), high resolution mass spectrometry (HRMS) and nuclear magnetic resonance spectrum (NMR) technique. Methods The unknown samples were dissolved in methanol solution containing internal standard SKF525A and detected by GC-MS and HRMS. The mixed samples were separated and purified by silica gel column chromatography, and then dissolved in methanol-d4 solution for structural analysis of 1H nuclear magnetic resonance spectroscopy (1H NMR). Results The characteristic fragment ions (m/z) were 86.1 (base peak), 71.2, 121.1, and 149.0, and the accurate mass number of molecular ion peak was measured by HRMS to be 236.128 89. By combined use of data analysis and database comparison, a new psychoactive substance of the cathinone class, Dibutylone, was detected in the sample, and the sample also contained a small amount of caffeine. The sample was purified, then identified using 1H NMR, and was further confirmed to be Dibutylone. In addition, the GC-MS retention time and characteristic fragment ions of the main components of the sample were consistent with those of Dibutylone reference material. Conclusion The method established in this study can be used for the identification of Dibutylone in mixed samples.

Abstract
Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion: The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

Abstract
Vocal expression is essential for conveying the emotion during social interaction. Although vocal emotion has been explored in previous studies, little is known about how perception of different vocal emotional expressions modulates the functional brain network topology. In this study, we aimed to investigate the functional brain networks under different attributes of vocal emotion by graph-theoretical network analysis. Functional magnetic resonance imaging (fMRI) experiments were performed on 36 healthy participants. We utilized the Power-264 functional brain atlas to calculate the interregional functional connectivity (FC) from fMRI data under resting state and vocal stimuli at different arousal and valence levels. The orthogonal minimal spanning trees method was used for topological filtering. The paired-sample t-test with Bonferroni correction across all regions and arousal-valence levels were used for statistical comparisons. Our results show that brain network exhibits significantly altered network attributes at FC, nodal and global levels, especially under high-arousal or negative-valence vocal emotional stimuli. The alterations within/between well-known large-scale functional networks were also investigated. Through the present study, we have gained more insights into how comprehending emotional speech modulates brain networks. These findings may shed light on how the human brain processes emotional speech and how it distinguishes different emotional conditions.

Background
The objective of this study was to develop a predicting model for estimating the odds of in-hospital death in the patients who receive extracorporeal membrane oxygenation (ECMO).
Methods
Adult patients who received ECMO for a variety of etiologies in our National University Hospital from 2005 and 2016 were included. The demographic, anthropometric, hemodynamic, and laboratory data when ECMO was instituted were recorded for each individual. A logistic regression model was applied to find the risk variables that were independently associated with in-hospital mortality. The predicted probability derived from the model was used to plot a receiver-operating-characteristic (ROC) curve, and area under curve (AUC) was found to represent the differentiating capacity of this approach.
Results
A total of 919 patients (659 men and 260 women) were included in the analysis. The mean age was 53.7[SD 15.9] years. The analysis showed that age (odds ratio [OR]: 1.018, 95% confidence interval [CI]: 1.008-1.028 per year), blood urea nitrogen (1.008 [1.001-1.014] per mg/dL), use of inotropic agent in terms of inotropic equivalent (1.007 [1.002-1.013]), the presence of cardiogenic shock (1.910 [1.097-3.327]), and the need of hemodialysis (2.262 [1.304-3.926]) were positively associated with mortality. In addition, body surface area (OR: 0.414 [0.204-0.840] per square meter), systolic blood pressure (0.995 [0.990-0.999] per mmHg), Glasgow Coma Scale (0.928 [0.899-0.957] per unit), pH value (0.395 [0.158-0.988] for each unit), and urine output (OR: 0.974 [0.964-0.985] per dL) were negatively associated with the probability of in-hospital death. The AUC in ROC analysis was 0.754 (95% CI: 0.722-0.787).
Conclusion
The predicting model that used a simple set of physiological parameters could substantially discriminate whether the patients receiving ECMO could survive the in-hospital course. Further studies are needed to examine why false positive and false negative predictions took place.

Abstract
Objective: To explore the association of the glycosylated hemoglobin (HbA1c) level at admission with 90 days functional outcome in patients with spontaneous intracerebral hemorrhage (ICH). Methods: Patients admitted to the Department of Neurology, Tongji Hospital from January to December 2017 were prospectively and continuously enrolled in this study. Clinical data were collected at admission and functional outcomes 90 days after ICH were assessed by using the modified RANKIN scale. Univariate and multivariate conditional logistic regression models were constructed. Patients were divided into four groups according to the quartile of HbA1c values. The median value of HbA1c in each group was taken as the substitute value and P for trend was calculated. The logistic regression model was fitted by restricted cubic splines to investigate the association between HbA1c level and outcome of ICH. Results: A total of 345 patients with ICH were enrolled, including 214 with favorable outcomes and 131 with poor outcomes (99 severe disability cases and 32 deaths). The risk of poor 90 days outcomes was significantly associated with HbA1c level at admission indicated by multivariate logistic regression analysis, and the P for trend test was <0.001 (middle-level group vs. low-level group: OR=2.33, 95%CI: 1.07-5.07; high-level group vs. low-level group: OR=2.52, 95%CI: 1.12-5.64; extremely high-level group vs. low-level group: OR=6.80, 95%CI: 3.01-15.34). Results from the restricted cubic spline showed that there was a linear correlation between HbA1c level at admission and poor 90 days outcomes of ICH (χ(2)=14.81, P<0.001; non- linear test: P=0.118). Compared with patients with HbA1c level of 6.5%, the risk of poor outcomes in patients with HbA1c level of <6.5% decreased linearly with the decrease in HbA1c level at admission, and the risk in patients with HbA1c level >6.5% was higher but not significantly. Conclusion: There was correlation between high HbA1c level at admission and 90 days poor outcome of ICH. High HbA1c level is an independent prediction indicator for ICH.

Abstract
Singlet exciton fission is a spin-allowed process in organic semiconductors by which one absorbed photon generates two triplet excitons. Theory predicts that singlet fission is mediated by intermolecular charge-transfer states in solid-state materials with appropriate singlet-triplet energy spacing, but direct evidence for the involvement of such states in the process has not been provided yet. Here, we report on the observation of subpicosecond singlet fission in mixed films of pentacene and perfluoropentacene. By combining transient spectroscopy measurements to nonadiabatic quantum-dynamics simulations, we show that direct excitation in the charge-transfer absorption band of the mixed films leads to the formation of triplet excitons, unambiguously proving that they act as intermediate states in the fission process.

Abstract
BACKGROUND Airborne pollutants have collectively been classified as a known human carcinogen and, more broadly, affect the health of hundreds of millions of people worldwide. Benzene is a frequent component of air pollution, and strategies to protect individuals against unavoidable exposure to this and other airborne carcinogens could improve the public's health. Earlier clinical trials in Qidong, China, demonstrated efficacy in enhancing the detoxication of benzene using a broccoli sprout beverage. OBJECTIVES A randomized, placebo-controlled, multidose trial of a broccoli sprout beverage was designed to determine the lowest effective concentration that enhances benzene detoxication adjudged by enhanced excretion of the urinary biomarker, S-phenylmercapturic acid (SPMA). METHODS Following informed consent, 170 subjects were randomly assigned in 5 blocks of 34 each to drink either a placebo beverage (n = 55) or 1 of 3 graded concentrations of a broccoli sprout beverage [full (n = 25), one-half (n = 35), and one-fifth (n = 55)] for 10 consecutive days. Concentrations of SPMA arising through induced benzene conjugation with glutathione were quantified by MS in sequential 12-h overnight urine collections during the intervention. RESULTS MS was also used to quantify urinary sulforaphane metabolites in each dosing regimen that resulted in a median 24-h urinary output of 24.6, 10.3, and 4.3 µmol, respectively, confirming a dose-dependent de-escalation of the inducing principle within the beverage. A statistically significant increase in benzene mercapturic acids in urine was found for the high-dose group (+63.2%) during the 10-d period. The one-half dose (+11.3%) and one-fifth dose groups (-6.4%) were not significantly different from placebo controls. CONCLUSIONS An intervention with a broccoli sprout beverage enhanced the detoxication of benzene, an important airborne pollutant, when dosed at a concentration evoking a urinary elimination of ∼25 µmol sulforaphane metabolites per day, and it portends a practical and frugal population-based strategy to attenuate associated long-term health risks of air pollution. This trial was registered at clinicaltrials.gov as NCT02656420.

Abstract
Objective: To screen the differentially expressed genes, functional enrichment and related signaling pathways in glioma by bioinformatics analysis. Methods: Microarray data of glioma related gene expression profiles were selected in GEO database, and differentially expressed genes in glioma patients and normal brain tissues were screened by R statistical software of lima package. Functional enrichment of differentially expressed genes (GO and KEGG) was performed. The protein-protein interaction database (STRING) was used to analyze the interaction between the screened differentially expressed genes and the related signaling pathways. Results: Two gene expression profiles, GSE15824 and GSE66354, were selected for analysis, and 158 genes with differential expression more than 2 times and P<0.05 were screened. Molecular function (MF) of 158 differentially expressed genes was integrin binding, cell adhesion molecule binding, calcium binding and AMPA glutamate receptor activity. Cell component localization (CC) was located in cell membrane, neuron cell body, axon of nerve cell and so on, while biological process (BP) was mainly cell adhesion and nervous system. Development, cell proliferation, GTPase activity, apoptosis and angiogenesis; KEGG signaling pathways were mainly cAMP signaling pathway, purine metabolism pathway, MAPK signaling pathway and cGMP-PKG signaling pathway. There were 177 interaction connections in 158 differential expression gene-protein interaction networks, with an average interaction of 2.39 between each node and an aggregation coefficient of 0.37. Cytohubb screened the key genes (hub genes) in the signaling pathway. The results indicated that SLC6A1,SLC1A2,BDNF,GAP43,NRXN1,GAD1,OLIG2, PLP1,S100B and GRIA3 were the key genes in the signaling pathway of the interacting protein network. All the 10 key genes were related to the prognosis of patients (P<0.05). Conclusions: There are differentially expressed genes profile in glioma tissues and normal tissues. SLC6A1, SLC1A2, BDNF, GAP43, NRXN1, GAD1, OLIG2, PLP1, S100B and GRIA3 are key genes for glioma development and are related to the prognosis of patients.

Abstract
The aqueous extract of Chinese winter jujube (Ziziphus jujuba Mill. cv. Dongzao) was used as reducing and capping agents for the synthesis of silver nanoparticles (AgNPs) for the first time. The resulting AgNPs were characterised by UV/Visible (UV-Vis) spectroscopy, atomic force microscope, transmission electron microscopy, selected area electron diffraction, X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray and Fourier transform infrared spectroscopy (FTIR). The colloidal solution of AgNPs gave a maximum UV-Vis absorbance at 446 nm. The synthesised nanoparticles were almost in the spherical shapes with an average size of 11.5 ± 4. 8 nm. FTIR spectra were applied to identify the functional groups which were possibly responsible for the conversion of metal ions into nanoparticles. The results showed that the prepared AgNPs were coated with the biomolecules in the extract. The biosynthesised AgNPs showed a remarkable catalytic activity at room temperature, and they also showed good antibacterial properties against Escherichia coli and Staphylococcus aureus.

Abstract
Depression is increasingly recognized as an inflammatory disease, with inflammatory crosstalk in the brain contributing its pathogenesis. Life stresses may up-regulate inflammatory processes and promote depression. Although cytokines are central to stress-related immune responses, their contribution to stress-induced depression remains unclear. Here, we used unpredictable chronic mild stress (UCMS) to induce depression-like behaviors in mice, as assessed through a suite of behavioral tests. C-X-C motif chemokine ligand 1 (CXCL1)-related molecular networks responsible for depression-like behaviors were assessed through intrahippocampal microinjection of lenti-CXCL1, the antidepressant fluoxetine, the C-X-C motif chemokine receptor 2 (CXCR2) inhibitor SB265610, and the glycogen synthase kinase-3β (GSK3β) inhibitor AR-A014418. Modulation of apoptosis-related pathways and neuronal plasticity were assessed via quantification of cleaved caspase-3, B-cell lymphoma 2-associated X protein, cAMP response element-binding protein (CREB), and brain-derived neurotrophic factor (BDNF) protein expression. CXCL1/CXCL2 expression was correlated with depression-like behaviors in response to chronic stress or antidepressant treatment in the UCMS depression model. Intrahippocampal microinjection of lenti-CXCL1 increased depression-like behaviors, activated GSK3β, increased apoptosis pathways, suppressed CREB activation, and decreased BDNF. Administration of the selective GSK3β inhibitor AR-A014418 abolished the effects of lenti-CXCL1, and the CXCR2 inhibitor SB265610 prevented chronic stress-induced depression-like behaviors, inhibited GSK3β activity, blocked apoptosis pathways, and restored BDNF expression. The CXCL1/CXCR2 axis appears to play a critical role in stress-induced depression, and CXCR2 is a potential novel therapeutic target for patients with depression.-Chai, H.-H., Fu, X.-C., Ma, L., Sun, H.-T., Chen, G.-Z., Song, M.-Y., Chen, W.-X., Chen, Y.-S., Tan, M.-X., Guo, Y.-W., Li, S.-P.
