Abstract
In 2019, we conducted a cross-sectional study for polio virus seroprevalence in Guangdong province, China. We assessed the positivity rates of poliomyelitis NA and GMT in serum across various demographic groups, and the current findings were compared with pre-switch data from 2014. Using multistage random sampling method, four counties/districts were randomly selected per city, and within each, one general hospital and two township hospitals were chosen. Healthy individuals coming for medical checkups or vaccination were invited. A total of 1318 individual samples were collected and tested. In non-newborn population, age-dependent positivity rates ranged from 77.8% to 100% for PV1 NA and 70.3% to 98.9% for PV3 NA (p < .01). The lowest GMT values for both types (17.03 and 8.46) occurred in the 20 to <30 years age group, while peak GMTs for PV1 and PV3 were observed in 1 to <2 (340.14) and 0 to <1-year (168.90) age groups, respectively. GMTs for PV1 (P = .002) and PV3 (P = .007) in Eastern Guangdong were lower than those in the other three regions. Male participants showed higher GMTs than females (P = .016 and .033, respectively). In newborn population, both males and females showed higher PV1 NA positivity rates and GMTs compared to PV3 (p < .05). Post-switch PV3 NA positivity rates were higher than pre-switch rates (p = .016). GMTs of both PV1 and PV3 were significantly higher post-switch (p < .001). The positivity rates of NAs and GMTs remain high level, which play an important role in resisting poliomyelitis infection. Effect of the converted immunization program was more pronounced than that before.

Abstract
PURPOSE Sublingual immunotherapy (SLIT) has been proven to be an effective and safe treatment for patients with house dust mite (HDM)-induced allergic rhinitis (AR) to achieve short-term and long-term efficacy. This study aimed to investigate the relationship between SLIT duration and long-term efficacy. MATERIALS AND METHODS This study involved 134 patients who underwent SLIT between 2019 and 2021 (in the 2-year group), between 2018 and 2021(in the 3-year group), or between 2017 and 2021 (in the 4-year group). The total nasal symptoms score (TNSS), total medication score (TMS), visual analogue scale (VAS), the Mini Rhinoconjunctivitis Quality of Life Questionnaire (MiniRQLQ) and adverse events (AEs) were assessed at baseline, after treatment (2021) and one year after the treatment completion (2022). The correlation between MiniRQLQ and other indicators was also analyzed. RESULTS After SLIT, patients in all three groups showed significant improvements in TNSS, TMS, VAS and MiniRQLQ scores (all p < 0.001). These improvements were sustained even one year after SLIT. Patients who received 3-4 years of SLIT showed significant improvement compared with those who received 2 years of SLIT in all clinical outcomes (all p < 0.01). The analysis showed positive correlations between the MiniRQLQ and TNSS, TMS, and VAS (all p < 0.001). No significant difference was observed in the AE rate in all three groups (p > 0.05). CONCLUSION Different duration of HDM SLIT could generate various short-term and long-term clinical efficacy. The MiniRQLQ could be applied to evaluate SLIT efficacy in clinical practice.

Abstract
Catalytic destruction of nitrogen oxides (NOx) combined with dust removal technique has attracted much attention, yet the application in the solid waste incineration air pollution control process is still lacking due to the complex flue gas atmosphere. In this work, the Mn-Ce-Co-Ox catalyst-coated polyphenylene sulfide (PPS) filter fiber with efficient dust removal and low-temperature polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) destruction has been prepared with a redox-precipitation method. The catalyst was uniformly grown around the PPS fiber with appropriate catalyst loading. The effects of several key operating parameters (e.g., reaction temperature, catalyst loading amount, and filtration velocity) on the catalytic efficiency were comprehensively investigated. The results show that the Mn-Ce-Co-Ox/PPS has a decomposition yield of 78.0% in PCDD/Fs and 96% in nitric oxide (NO) conversion at 200 °C. The poisoned catalytic filter exhibits a removal efficiency of 88.6% for PCDD/Fs. In addition, the catalytic filter can completely reject particles smaller than 1.0 μm with a low filtration resistance. Therefore, this efficient and energy-conserving catalytic filter shows promising applications in flue gas pollution treatments.

Abstract
Objective: To study the infection status and epidemiological characteristics of parainfluenza virus (PIV) in acute respiratory tract infection adult cases in Shanghai from 2015 to 2021, and to provide a scientific basis for preventing and controlling PIV. Methods: Acute respiratory tract infections were collected from 13 hospitals in Shanghai from 2015 to 2021. Relevant information was registered, and respiratory specimens were sampled to detect respiratory pathogens by multiplex PCR. Results: A total of 5 104 adult acute respiratory tract infection cases were included; the overall positive rate of the respiratory pathogens was 29.37% (1 499/5 104). The positive rate of PIV was 2.61% (133/5 104), compared with 2.32% (55/2 369) and 2.85% (78/2 735) in influenza-like cases (ILI) and severe acute respiratory infection (SARI) cases, respectively. Among them, PIV3 accounted for the highest proportion (62.41%, 83/133), followed by PIV1 (18.80%, 25/133), PIV2 (9.77%, 13/133), and PIV4 (9.02%, 12/133). The incidence of PIV-positive cases was mainly distributed in the first and second quarters, accounting for 62.41% (83/133). The difference in the incidence in each quarter was significant (χ2=24.78, P<0.001). Mixed infection accounted for 18.80% (25/133) of 133 PIV-positive cases, the mixed infection rates of ILI and SARI were 18.18% (10/55) and 19.23% (15/78), respectively, and the main mixed pathogen of PIV was coronavirus 229E. Conclusions: There are a certain proportion of PIV-positive acute respiratory tract infection cases in Shanghai. It is necessary to strengthen the etiological surveillance in acute respiratory tract infection cases, especially the mixed infection of PIV and other pathogens.

Abstract
PURPOSE/OBJECTIVE(S) The combination of immunotherapy and chemoradiotherapy has widely used for patients with esophageal squamous cell carcinoma (ESCC) and induced treatment-related adverse effects, particularly immune checkpoint inhibitor-related pneumonitis (CIP) and radiation pneumonitis (RP). The aim of this study is to differentiate between CIP and RP by the CT radiomics and clinical or radiological parameters. MATERIALS/METHODS A total of 76 ESCC patients with pneumonitis were enrolled in this retrospective study and divided into training dataset (n = 53) and validation dataset (n = 23). A total of 837 radiomics features were extracted from regions of interest (ROIs) based on the lung parenchyma window of CT images. A radiomics signature was constructed on the basis of the predictive features by the least absolute shrinkage and selection operator (LASSO). A logistic regression was applied to develop radiomics nomogram. Receiver operating characteristics (ROC) curve and area under the curve (AUC) were applied to evaluate the performance of pneumonitis etiology identification. RESULTS No significant difference was detected between training dataset and validation dataset. The radiomics signature which was made up of four radiomics features shown a favorable performance on differentiating between CIP and RP with the α-binormal-based and empirical AUC = 0.831 and 0.843. Patients with RP had a close relationship with location (p = 0.003) and shape of lesions (p = 0.002). The nomogram that combined with radiomics signature and clinical factors improved the classifying performance on discrimination in the training dataset (AUCαbin = 0.963 and AUCemp = 0.964). The results were verified in the validation dataset with AUC = 0.967 and 0.964. CONCLUSION CT-based radiomics features have potential values for differentiating between patients with CIP and RP. Addition of bilateral changes and sharp border produced superior model performance on classifying, which could be a useful method to improve related clinical decision-making.

Abstract
With the concept of sustainable management of plantations, individual trees with excellent characteristics in plantations have received attention from breeders. To improve and maintain long-term productivity, accurate and high-throughput access to phenotypic characteristics is essential when establishing breeding strategies. Meanwhile, genetic diversity is also an important issue that must be considered, especially for plantations without seed source information. This study was carried out in a ginkgo timber plantation. We used simple sequence repeat (SSR) markers for genetic background analysis and high-density terrestrial laser scanning for growth structural characteristic extraction, aiming to provide a possibility of applying remote sensing approaches for forest breeding. First, we analyzed the genetic diversity and population structure, and grouped individual trees according to the genetic distance. Then, the growth structural characteristics (height, diameter at breast height, crown width, crown area, crown volume, height to living crown, trunk volume, biomass of all components) were extracted. Finally, individual trees in each group were comprehensively evaluated and the best-performing ones were selected. Results illustrate that terrestrial laser scanning (TLS) point cloud data can provide nondestructive estimates of the growth structural characteristics at fine scale. From the ginkgo plantation containing high genetic diversity (average polymorphism information content index was 0.719) and high variation in growth structural characteristics (coefficient of variation ranged from 21.822% to 85.477%), 11 excellent individual trees with superior growth were determined. Our study guides the scientific management of plantations and also provides a potential for applying remote sensing technologies to accelerate forest breeding.

Abstract
Objective: To analyze the epidemiological characteristics and related factors of hepatitis C in Beijing City from 2004 to 2021. Methods: Descriptive epidemiological method and Joinpoint regression were used to analyze the trend and other epidemiological characteristics of hepatitis C in Beijing City from 2004 to 2021 in National Notifiable Disease Reporting System. According to a 1∶1 matched case-control study design, logistic regression was used to investigate the risk factors of hepatitis C infection in 2021. Results: From 2004 to 2021, the reported incidence of hepatitis C in Beijing City ranged from 2.37/100 000 to 10.46/100 000. The reported cases were mainly aged 30-60 years, and most of them were chronic. The reported incidence of hepatitis C showed an initial increase from 2004 to 2006 (APC=45.37%, 95%CI:-1.56%-114.69%), and declined after 2006 (APC=-9.21%, 95%CI:-10.70%-7.70%). Logistic analysis showed that history of surgery (OR=1.84, 95%CI: 1.08-3.14) and previous blood transfusion (OR=34.22, 95%CI: 8.05-145.41) were risk factors for hepatitis C infection. Conclusion: The reported incidence of hepatitis C in Beijing City increases first and decreases later. It currently remains at a low level. The risk factors of infection are surgery and blood transfusion history. Safe blood supply and preventing iatrogenic transmission should be focused on the prevention of hepatitis C transmission.

Abstract
Objective: To explore the effects of hyperandrogenism (HA) on pregnancy outcomes in women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET). Methods: A retrospective study was conducted on infertile women with PCOS undergoing IVF/ICSI-ET from January 2017 to June 2021 in our center. Patients were divided into HA group and NON-HA group according to the levels of testosterone. Propensity score matching (PSM) was used to balance the influence of female age and IVF/ICSI-ET for patients with gonadotropin-releasing hormone (GnRH)antagonist protocol and GnRH agonist protocol, separately. After the PSM procedure, 191 cases in HA group and 382 cases in NON-HA group, were included. Hormone levels and pregnancy outcomes were compared in the two groups. Results: The female age was comparable in two groups [HA: (29.6±3.7) vs NON-HA: (29.5±3.6), P=0.665]. The basal luteinizing hormone [(10.82±6.73) vs (7.76±5.30) IU/L], testosterone [(3.27±0.97) vs (1.60±0.59) nmol/L], free androgen index (7.13 vs 2.77), anti-mullerian hormone [(11.37±5.74) vs (9.67±4.67) ng/ml], fasting glucose [(5.18±0.49) vs (5.06±0.42) mmol/L], 1h glucose [(9.34±2.42) vs (7.99±2.21) nmol/L], 2 h glucose [(7.66±2.17) vs (6.64±1.84) nmol/L], 2 h insulin [(129.81±145.49) vs (97.51±86.92) mU/L], total cholesterol [(5.35±0.89) vs (4.92±0.92) mmol/L], triglycerides [(1.55±1.28) vs (1.33±0.77) mmol/L], and low density lipoprotein cholesterol levels [(3.38±0.66) vs (3.14±0.71) mmol/L] were significantly higher in HA group, compared with NON-HA group (P<0.05). The initiated gonadotropin dose was higher in HA group than that in NON-HA group [(126.96±33.65) vs (137.60±38.12) U, P=0.001], but moderate-severe ovarian hyperstimulation syndrome (OHSS) rate was similar in two groups (P>0.05). The rates of implantation, clinical pregnancy, miscarriage, and live birth were comparable between the two groups (P>0.05). Also, in the subgroups, the rates of implantation, clinical pregnancy, live birth, and miscarriage were similar in HA group and NON-HA group. Conclusions: The risks of hormonal abnormality and glucose-lipid metabolic disorder were higher in PCOS women with HA, whereas satisfactory pregnancy outcomes could be achieved under proper ovarian stimulation undergoing IVF/ICSI-ET.

Abstract
Climatic change causes obvious seasonal meteorological drought in southern China, yet there is a lack of comprehensive in situ studies on the effects of drought in Eucalyptus plantations. Here, a 50% throughfall reduction (TR) experiment was conducted to investigate the seasonal variations of soil bacterial and fungal communities and functions in a subtropical Eucalyptus plantation and their responses to TR treatment. Soil samples were collected from control (CK) and TR plots in the dry and rainy seasons and were subjected to high-throughput sequencing analysis. Results showed that TR treatment significantly reduced soil water content (SWC) in the rainy season. In CK and TR treatments, fungal alpha-diversity decreased in the rainy season while bacterial alpha-diversity did not change significantly between dry and rainy seasons. Moreover, bacterial networks were more affected by seasonal variations compared with fungal networks. Redundancy analysis showed that alkali hydrolyzed nitrogen and SWC contributed the most to the bacterial and fungal communities, respectively. Functional prediction indicated that the expression of soil bacterial metabolic functions and symbiotic fungi decreased in the rainy season. In conclusion, seasonal variations have a stronger effect on soil microbial community composition, diversity, and function compared with TR treatment. These findings could be used to develop management practices for subtropical Eucalyptus plantations and help maintain soil microbial diversity to sustain long-term ecosystem function and services in response to future changes in precipitation patterns.

Abstract
People may perceive and expose negative sentiments in days with PM2.5 pollutions, but evidence is still insufficient about the joint effects of PM2.5 and socioeconomic factors on human sentiments. In this study, a total of 8032 facial photos of urban green space visitors were obtained from Sina Weibo in 50 cities of East China and rated for happy, sad, neutral scores and net positive emotion index (NPE; happy minus sad). Seasonal air PM2.5 concentrations were collected from days when people exposed faces in cities that were categorized to medium, large, outsize, and mega sizes according to resident populations (RPs). In summer, people posted lower sad score (11.28 %) than in winter (13.51 %; P = 0.0357) and higher NPE (35.86 %) than in autumn (30.92 %; P = 0.0009). Multivariate linear regression on natural logarithms revealed that factors of gross domestic product per capita (parameter estimate: 0.45), RP (0.59), non-production electricity consumption (0.34), and length of road transport (0.34) together generated positive contributions to posted happy score, while the total retail trade of consumer goods (-1.25) and PM2.5 (-0.50) were perceived as joint depressors on NPE. Overall, cities with more rich households and activated retail sales attracted more people who exposed smiles in weathers with PM2.5 compared to cities where local economy is reliable on heavy industry. The summertime in mega cities will be recommended to enjoy a higher frequency to perceive satisfaction due to exposure to low PM2.5.

Abstract
Forests in urban areas provide great healthcare benefits to citizens, but it is less well known whether this benefit is related to different geographical spaces. We selected exurban forest, suburban forest, downtown forest, and urban control in Guangzhou, China to analyze the change characteristics of negative air ion concentration (NAIC), air oxygen content (AOC), and human comfort index (HCI). Based on Criteria Importance Through Intercriteria Correlation (CRITIC) method, the urban forest comprehensive healthcare index (UFCHI) was established. Finally, the evaluation criteria for UFCHI were identified by cluster analysis. The results demonstrated that (1) The NAIC in exurban forest (2,713 ± 1,573 ions/cm3) and suburban forest (2,147 ± 923 ions/cm3) was evidently better than downtown forest (1,130 ± 255 ions/cm3) and urban control (531 ± 162 ions/cm3). (2) The AOC was in the order of exurban forest (21.17 ± 0.38%) > suburban forest (21.13 ± 0.30%) > downtown forest (21.10 ± 0.16%) > urban control (20.98 ± 0.12%). (3) The HCI in urban control (5.56 ± 2.32) and downtown forest (5.15 ± 1.80) is higher than suburban forest (4.02 ± 1.53) and exurban forest (3.71 ± 1.48). (4) The UFCHI in exurban forest (1.000), suburban forest (0.790), and downtown forest (0.378) were beneficial to human health to some extent, while urban control (0.000) was at Level IV, having no healthcare benefit. Except in winter, the UFCHI in exurban forest and suburban forest were all at Level II and above; while downtown forest and urban control were all at Level III and below at all seasons. Overall, urban forests in the exurbs and suburbs have better healthcare benefits than those in the downtowns. Furthermore, it is recommended that urban residents visit exurban and suburban forests for forest therapy in spring, summer, and autumn.

Abstract
Urban residents have a higher risk of hypertension and psychological stress than rural residents. Aside from medical interventions, understanding how to control hypertension and alleviate the stress of urban populations has become a public concern. As an alternative medical measure, forest therapy has shown the effects of normalizing blood pressure (BP) and reducing stress increasingly in recent literature, but this is still inconclusive. In order to systematically verify forest therapy’s effects on the BP and mental stress of urban residents, we conducted meta-analyses to assess the changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and salivary cortisol concentration (SCC; a stress biomarker) between the forest therapy group and urban control group. We searched 4 online databases, and 21 studies on BP involving 2270 participants and 13 studies on SCC involving 1786 participants were included. Through the meta-analysis, the mean difference and confidence interval (CI) estimates indicated that forest therapy significantly reduced participants’ SBP −3.44 (95% CI −5.74, −1.14), DBP −3.07 (95% CI −5.59, −0.54), and SCC −0.07 (95% CI −0.10, −0.04), as compared with urban control. Yet, there was substantial heterogeneity (I2 = 72.87−88.59%) among these studies. We also found that each prediction interval (PI) for SBP (95% PI −13.30, 6.42), DBP (95% PI −15.54, 9.41), and SCC (95% PI −0.18, 0.05) were all much wider than the CIs and contained values above 0. This means that forest therapy may reduce SBP, DBP, and SCC on average, but may not exclude adverse results. Meta-regression analyses showed that participants’ age and baseline SBP levels determined the heterogeneity among SBP studies. After forest therapy, older participants and those with higher baseline SBP levels had greater SBP-lowering effects. Among DBP studies, the primary source of heterogeneity was participants’ baseline DBP levels; participants with higher baseline DBP levels had greater DBP reduction. In subgroup analyses, we discovered that longer-term forest therapy programs (≥20 min) resulted in a greater reduction in BP and SCC than shorter-term forest therapy programs (<20 min). Additionally, seated viewing, walking, or multi-session programs in forests were observed to have similar effects on reducing BP and SCC. Despite extensive analyses, the study did not identify any sources of heterogeneity among forest therapy programs for lowering SCC levels. Overall, we conclude that forest therapy programs have beneficial therapeutic effects on urban residents’ physio-psychological health through lowering BP and relieving stress (reducing SCC). This finding provides solid evidence of the contribution of forest therapy to urban residents’ health and wellbeing.

Abstract
Despite the importance of non-structural carbohydrates (NSC) for growth and survival in woody plants, we know little about whole-tree NSC storage. Here, Catalpa bungei trees fertilized using different schedules, including water and fertilizer integration, hole application, and no fertilization, were used to measure the spatial variations of sugar, starch, and NSC concentrations in the leaf, branch, stem, bark, and root. By calculating the volume of whole-tree NSC pools and the contribution of distinct organs, we were also able to compare the storage under various fertilization regimes. We found that the spatial distribution patterns of each organ undergoing different fertilization regimes were remarkably similar. Height-related increases in the sugar and NSC concentrations of the leaf and bark were observed. The concentrations of sugar and NSC in the branch did not appear to vary longitudinally or horizontally. The sugar and NSC concentrations in the stem fluctuated with height, first falling and then rising. The coarse root contained larger amounts of NSC components in comparison to fine root. Contrary to no fertilization, fertilization enhanced the distribution ratio of the leaf, branch, and stem NSC pools while decreasing the distribution ratio of the root NSC pool. Particularly, the addition of fertilizer and water significantly increased the biomass of the organs, enhancing the carbon sink of each organ and whole-tree in comparison to other fertilization regimes. Our main goal was to strengthen the empirical groundwork for comprehending the functional significance of NSC allocation and stock variations at the organ-level of C. bungei trees.

Abstract
Fertilization is a fundamental aspect of global forest management that enhances forest productivity and drastically affects soil microbial communities. However, few studies have investigated the differences and similarities in the responses of below-ground microbial communities to different fertilization schemes. The effects of fertilization regimes on the composition and diversity of soil fungal and bacterial communities were investigated in a young Catalpa bungei plantation in Shandong Province, Eastern China. Soil microbial communities were assessed undergoing three types of fertilization: (i) no fertilization (CK), (ii) hole fertilization (HF), and (iii) the integration of water and fertilizer (WF). We further analyzed the effects of soil depth (i.e., 0–20 and 20–40 cm) on the structure of soil microbial communities. Our results indicated that the diversity of bacteria (e.g., Chao1 and Shannon indices) reduced undergoing fertilization, and WF had a higher negative impact on bacterial diversity than HF. A lower bacterial diversity was observed in the subsoil compared to the topsoil. In contrast to bacterial diversity, fungal diversity had a slightly increasing trend in the fertilized environments. The primary bacterial function was metabolism, which was independent of fertilization or soil depth. Among fungal functional guilds, symbiotic soil fungi decreased obviously in the fertilized stand, whereas saprotrophic fungi increased slowly. According to the structural equation models (SEM), the diversity and composition of bacterial and fungal communities were jointly regulated by soil nutrients (including N and P contents) directly affected by fertilization and soil layer. These findings could be used to develop management practices in temperate forests and help sustain soil microbial diversity to maintain long-term ecosystem function and services.

Abstract
Objective Coronary artery disease (CAD) has been one of the leading causes of morbidity and mortality worldwide. Cardiac shock wave therapy (CSWT) is a novel and non-invasive therapy for CAD. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy of CSWT on CAD. Methods and results We performed a comprehensive search of electronic databases such as PubMed, Embase, the Cochrane Library, and Wanfang Data in October 2021. The results were reported as weighted mean difference (WMD) with a 95% confidence interval (CI). Statistical heterogeneity scores were assessed with the standard Cochran's Q test and the I 2 statistic. A total of 8 randomized trials and 2 prospective cohort studies, together involving 643 patients (n = 336 CSWT and n = 307 control), were included in our study. Eight studies with 371 patients showed significantly improved rest left ventricular ejection fraction (LVEF) with CSWT as compared to that of the control group (WMD 3.88, 95% CI 1.53-6.23, p = 0.001, I 2 = 51.2%). Seven studies with 312 patients reported left ventricular internal diameter in diastole (LVIDd) were markedly decreased in the CSWT group compared to the control group (WMD -1.81, 95% CI -3.23 to -0.39, p = 0.012, I 2 = 20.3%). The summed stress score significantly favored the CSWT group (WMD -3.76, 95% CI -6.15 to -1.37, p = 0.002, I 2 = 56.8%), but there was no significant difference for the summed rest score. Our data were acquired from studies without a perceived high risk of bias, so plausible bias is unlikely to seriously affect the main findings of the current study. Conclusion Based on data from our present meta-analysis, CSWT was shown to moderately improve myocardial perfusion and cardiac function among patients with CAD, which would provide the clinicians with a meaningful and valuable option. Systematic Review Registration The meta-analysis was registered on the Open Science Framework (OSF) (https://osf.io/r2xf9).

Abstract
Nutrient management in Eucalyptus plantations is critical for wood production and sustainable development. The biogeochemical mechanisms in Eucalyptus plantations are not fully understood due to changes in the spatiotemporal pattern of precipitation and plantation management. The nutrients released from litterfall are important sources of soil nutrition. We measured the seasonal production of various litterfall types and the proportions of their released nutrients in Eucalyptus urophylla × E. grandis plantations under compound fertilization, dry-season irrigation, and a combined compound fertilization and dry-season irrigation treatment. Our results showed that fertilization increased aboveground biomass and annual litterfall production (except leaf), and that the peak of litterfall production occurred in the rainy season. We found that the decomposition rates of leaf were significantly higher than that of twig, which were mainly controlled by stoichiometric characteristics, followed by soil enzyme activity (β-glucosidase, urease, and polyphenol oxidase). Fertilization decreased the carbon: nitrogen ratio and carbon: phosphorus ratio in litter, and increased soil enzyme activities, which accelerates litter decomposition and nutrient release. Dry-season irrigation increased litter decomposition and only affected the proportion of released potassium by changing the carbon: potassium ratio. Fertilization and dry-season irrigation accelerated the nutrient cycle to enhance compensatory growth. These results help to comprehend the effects of forest management on litterfall dynamics and decomposition processes in Eucalyptus plantations with seasonal drought.

Abstract
OBJECTIVE To investigate the expression of aldehyde dehydrogenase 3B1 (ALDH3B1) in gastric cancer and explore its correlation with the pathological parameters and long-term prognosis of the patients. METHODS We analyzed the clinical data of 101 patients who underwent radical gastrectomy for gastric cancer in our hospital between January, 2013 and November, 2016, and examined the expression of ALDH3B1 in paraffin-embedded samples of gastric cancer tissues and adjacent tissues from these cases by immunohistochemical staining. We evaluated the correlation between ALDH3B1 expressions and histopathological parameters and assessed the predictive value of ALDH3B1 expression for long-term survival of the patients. We also examined the effect of lentivirus-mediated interference and overexpression of ALDH3B1 on the malignant behaviors of MGC-803 gastric cancer cells. RESULTS The expressions of ALDH3B1 and Ki67 were significantly higher in gastric cancer tissues than in adjacent tissues (P < 0.05). In gastric cancer patients, ALDH3B1 expression was positively correlated with peripheral blood CEA and CA19-9 levels (P < 0.01). The proportion of patients with CEA ≥5 μg/L, CA19-9 ≥37 kU/L, T stage of 3- 4, and N stage of 2-3 was significantly greater in high ALDH3B1 expression group than in low expression group. Kaplan-Meier survival analysis showed that the 5-year survival rate was significantly lower in gastric cancer patients with high ALDH3B1 expressions (P < 0.01). Univariate and Cox multiple regression analyses identified a high expression of ALDH3B1 (P < 0.05, HR= 0.231, 95% CI: 0.064-0.826), CEA≥5 μg/L (P < 0.01, HR=4.478, 95% CI: 1.530-13.110), CA19-9≥37 kU/L (P < 0.01, HR=3.877, 95% CI: 1.625-9.247), T stage of 3-4 (P < 0.01, HR=4.953, 95% CI: 1.768-13.880), and N stage of 2-3 (P < 0.05, HR=2.152, 95% CI: 1.152-4.022) as independent risk factors affecting 5-year survival after radical gastrectomy. The relative ALDH3B1 expression level, at the cut-off point of 4.66, showed a sensitivity of 76.47% and a specificity of 76% for predicting 5-year postoperative death (P < 0.01). In the cell experiment, overexpression of ALDH3B1 obviously promoted the proliferation, migration and invasion of MGC-803 cells. CONCLUSION As an independent risk factor affecting 5-year survival after radical gastrectomy, ALDH3B1 is highly expressed in gastric cancer and correlated with pathological parameters of the tumor, and a high ALDH3B1 expression may promote proliferation, invasion and metastasis of gastric cancer cells.

Abstract
OBJECTIVE To study the effect of Yishen Tongluo Prescription (YTP) on the testis tissue of the male rats with oligoasthenospermia (OAS) and its action mechanism based on the PI3K-AKT-mTOR pathway. METHODS We randomly divided 48 SPF male SD rats into 8 groups: normal control, OAS model control, L-carnitine (LC), high-dose YTP, low-dose YTP, Omipalisib inhibitor (OI), OI + high-dose YTP, and OI + low-dose YTP, with 6 rats in each group. We established a model of OAS in the latter 7 groups by intragastric administration of tripterygium wilfordii polyside, followed by intervention with corresponding drugs. After treatment, we obtained semen parameters from the rats, observed pathological changes in the testis tissue by HE staining, and determined the expressions of the PI3K-AKT-mTOR signaling pathway-related proteins and mRNA by Western blot and real-time fluorescence quantitative PCR (qRT-PCR). RESULTS Sperm concentration and total sperm motility were significantly improved in the LC and YTP groups compared with those in the OAS model control group (P < 0.001). HE staining showed irregularly arranged spermatogenic cells and narrowed lumina and widened gaps of seminiferous tubules in the OAS model controls, as well as similar pathological changes in the LC, YTP and OI + YTP groups. Significant up-regulation was observed in the protein expressions of p-Akt, CatSper-1 and HSPA2 in the LC group (P < 0.05), those of p-Akt, mTOR, catsper-1 and HSP2 in the low-dose YTP group (P < 0.05) and that of PI3K in the high-dose YTP group (P < 0.05) compared with those in the model controls. There were no statistically significant differences in the expressions of PI3K, mTOR and catsper-1 between the OI and model control groups (P > 0.05), nor in those of PI3K, p-Akt, mTOR, CatSper-1 and HSPA2 between the OI + YTP and the former two groups (P > 0.05). The mRNA expressions of PI3K, mTOR, CatSper-1 and HSPA2 were remarkably higher in the LC and YTP groups than in the model control (P< 0.05), with those of catsper-1 and PI3K even more significantly up-regulated in the high-dose than in the low-dose YTP group (P< 0.001; P< 0.05). Statistically significant differences were not observed in the mRNA expressions of PI3K, mTOR, CatSper-1 and HSPA2 between the model control and OI groups (P > 0.05), nor in those of PI3K, mTOR, catsper-1 and HSPA2 between the model control and OI + YTP groups (P > 0.05). CONCLUSION Yishen Tongluo Prescription can improve sperm quality and pathological changes of the testis tissue in rats with Tripterygium glycoside-induced OAS, which might be attributed to its ability of up-regulating the expressions of the PI3K Akt mTOR pathway-related proteins and mRNA in the testis tissue.

Abstract
Objective: To investigate the effect of programmed death receptor (PD)-1 antibody therapy in patients with hepatitis B-associated liver cancer. Methods: Data of 29 chronically infected HBV patients with liver cancer who received PD-1 antibody combined with tyrosine kinase inhibitor in the Department of Infectious Diseases of the Fifth Medical Center of PLA General Hospital from March 2020 to January 2021 were selected. At the same time, all of the above-mentioned hepatitis B virus (HBV) patients were treated with nucleos(t)ide analogues. Patients clinical diagnostic data, laboratory test results, tumor response and the incidence of adverse reactions were collected retrospectively to understand the overall safety, therapeutic anti-tumor effect, HBV changes condition and the correlation between HBV changes and anti-tumor PD-1 antibody efficacy, high viral load treatment condition, and HBV reactivation safety issues. Statistical analysis was performed by non-parametric rank sum test. Results: Therapeutic anti-tumor effect and safety profile were good in patients. The complete remission rate was reached 27.6%. Adverse reactions were mostly mild, and the incidence of serious adverse reactions was low. After 12 weeks of follow-up, HBV DNA and hepatitis B surface antigen (HBsAg) was quantitatively decreased (P < 0.05). HBV DNA and HBsAg were decreased more significantly in patients with progressive disease (PD), stable disease (SD) and partial response (PR) (P < 0.05). Five patients with HBV DNA ≥ 10(4) IU/ml had responded well to the tumor treatment without serious adverse reactions. One patient had a slight increase in HBV DNA and alanine aminotransferase, while there was no HBV reactivation and correlated liver damage. Conclusion: Patients with HBV-associated liver cancer who received combined therapy have good anti-tumor efficacy and safety profile. PD-1 treatment has a certain effect on HBV. Compared with non-responders, patients with tumor response have better antiviral treatment efficacy. The safety of treatment in patients with high viral load is manageable, and there are no safety issues related to HBV reactivation.

Abstract
This paper presents the communication strategy for second-order multi-agent systems with nonlinear dynamics. To address the problem of the scarcity of communication channel resources and get rid of using continuous signals among the followers in lead-follower multi-agent systems, a novel event-triggered communication mechanism is proposed in this paper. To avoid employing the centralized information that depends on the Laplacian matrix spectrum, a network protocol with updated coupling gains is proposed, as well as an event-triggered strategy with updated thresholds. To eliminate the ill effects of inter-node communicating noise, relative positions are employed by the protocol instead of absolute positions. By a Lyapunov-Krasovskii functional, it is rigorously proven that the leader-following consensus of MASs is achieved without Zeno behavior, under the control of the proposed protocol with an event-triggered mechanism communication. The effectiveness of the proposed protocol is verified through numerical examples.

Abstract
Objective: To analyze the clinical characteristics and long-term prognosis of implantation of drug-eluting stents (DES) for elderly patients with unprotected left main artery (ULM) disease. Methods: A total of 414 patients (327 males and 87 females) who underwent DES implantation were enrolled in the Department of Cardiology, Beijing Anzhen Hospital from January 2005 to March 2010, with a mean age of (61.5±10.7) years old. The patients were divided into two groups according to age: 300 cases in the group of age <70 years old, and 114 cases in the group of age ≥70 years old. The clinical characteristics and long-term prognosis of two groups were compared. Results: In the group of age ≥ 70 years old, the proportion of female was higher (31.6% vs 17.0%, P=0.001) and the incidence of chronic total occlusion (CTO) (P=0.020), hypertension (P=0.018) and cerebrovascular disease (P=0.013) were higher than those in the group of <70 years old. All-cause mortality and cardiac mortality were also higher than those in the group of <70 years old (P=0.025, P=0.013). The follow-up period was (21.4±9.6) months. After adjusting for multiple clinical factors, there were no statistical differences of incidence of the total major adverse cardiac and cerebral events (MACCE), myocardial infarction, cerebrovascular events, and revascularization recurrence between the two groups. But all-cause mortality (HR=3.790, 95%CI: 1.271-11.298, P=0.017) and cardiac mortality (HR=17.424, 95%CI: 2.440-124.410, P=0.004) in the group of age ≥70 years old were still remarkably higher than those in the group of <70 years old. Conclusions: Age is an independent risk factor for increased mortality after DES stent implantation in ULM disease. DES stent implantation in age ≥70 years old patients with ULM disease is considered feasible, but it needs to be treated with caution.

Abstract
Objective: To analyze the influencing factors of acute kidney injury (AKI) in patients after cardiac surgery using levosimendan or dobutamine, and explore the effect of positive inotropic drugs on AKI. Methods: The clinical data of 417 patients undergoing cardiac surgery from January to June 2018 in Beijing Anzhen Hospital and treated with levosimendan or dobutamine during perioperative period were retrospectively reviewed and collected. Patients were divided into AKI group and non-AKI group according to whether AKI occurred. Univariate logistic regression analysis was used to analyze the factors related to the occurrence of AKI. The statistically significant factors (P<0.05) were further included in the multivariate logistic regression analysis. Results: Totally, 417 patients were enrolled in the study, with a mean age of (58.2±10.4) years old and a male rate of 65.0% (n=271), and the AKI incidence rate was 25.2% (105/417). Univariate logistic regression analysis showed that male, chronic kidney disease, high serum creatinine level in preoperative period, aortic obstruction time ≥ 120 minutes and extracorporeal circulation time ≥ 120 minutes were risk factors for AKI (all P<0.05). Vasodilator and levosimendan treatment during perioperative period were protective factors (P<0.05). Multivariate logistic regression analysis showed that chronic kidney disease (OR=17.291, 95%CI: 4.335-68.960, P<0.001) and high serum creatinine level (OR=1.097, 95%CI: 1.074-1.121, P<0.001) in preoperative period were independent risk factors for AKI. Perioperative application of levosimendan (OR=0.533, 95%CI: 0.288-0.984, P=0.044) was an independent protective factor. Conclusions: Risk factors for AKI after cardiac surgery include chronic kidney disease and high serum creatinine level in preoperative period. The use of levosimendan during preoperative period has the potential effect to protect against AKI.

Abstract
Objective: To investigate chromosome abnormality rate and related factors of spontaneous abortion in early pregnancy. Methods: A total of 831 tissue samples of spontaneous abortion in early pregnancy were collected from June 2015 to August 2018 in the First Affiliated Hospital of Nanjing Medical University. Chromosomal copy number was analyzed by next generation sequencing (NGS). The relationships between chromosome abnormality and maternal age, in vitro fertilization-embryo transfer (IVF-ET) pregnancy, number of previous spontaneous abortions, history of live birth were analyzed by statistical methods. Results: Among 831 tissue samples of spontaneous abortion in early pregnancy, 461 (55.5%, 461/831) were found to have chromosome abnormalities. Maternal age (OR=1.107, 95%CI: 1.070- 1.145) and history of live birth (OR=1.909, 95%CI: 1.182-3.083) were the positive correlative factors of chromosome abnormality. Times of previous spontaneous abortion (OR=0.807, 95%CI: 0.702-0.928) and IVF-ET pregnancy (OR=0.554, 95%CI: 0.404-0.760) were the negative correlative factors of chromosome abnormality. Conclusions: Chromosome abnormality is an important cause of spontaneous abortion in early pregnancy. The rate of chromosome abnormality increases with the increase of maternal age and the history of live birth, and decreases with the increase of number of previous spontaneous abortion and IVF-ET pregnancy.

Abstract
Cardiac shock wave therapy (SWT) has been described as a novel therapeutic strategy that is able to alleviate myocardial ischemic injury. microRNA (miRNA/miR)‑210 plays a cytoprotective role in cardiomyocytes in response to hypoxia by regulating cell apoptosis. The aim of the present study was to investigate whether cardiac SWT could protect cardiomyocytes from hypoxia‑induced injury by regulating miR‑210 expression. The murine adult cardiomyocyte cell line HL‑1 was incubated for 5 h in hypoxic conditions, followed by reoxygenation for 12 h and treatment with SWT immediately following hypoxia in the present study. The cell viability was determined using an MTS assay. Western blot analyses were performed in order to detect cell signaling changes. Reactive oxygen species production was detected using dihydroethidium staining, and malondialdehyde levels were measured using the thiobarbituric acid method. miRNA and mRNA expression levels were confirmed via reverse transcription‑quantitative PCR. Apoptosis was evaluated by means of flow cytometry. HL‑1 cells were then transfected with miR‑210 mimics or inhibitors in order to alter miR‑210 expression levels, and the effects on HL‑1 cells were determined. Hypoxia led to elevated oxidative stress, enhanced cell apoptosis and upregulated miR‑210 expression levels in HL‑1 cells, while SWT could alleviate hypoxia‑induced cell injury and further promote miR‑210 expression. miR‑210 overexpression decreased apoptosis and oxidative stress during hypoxic stress in HL‑1 cells, whereas inhibition of miR‑210 increased cell apoptosis and promoted oxidative stress. Furthermore, miR‑210 inhibition could reverse the effects of SWT on HL‑1 cells. Finally, the mRNA analysis revealed that SWT significantly attenuated apoptosis‑inducing factor mitochondrion‑associated 3 and caspase 8 associated protein 2 mRNA expression levels in cardiomyocytes exposed to hypoxia, which were two targets of miR‑210. SWT could exert cardioprotective effects against hypoxia‑induced cardiac injury by modulating miR‑210.

Abstract
Doxorubicin, as a first line chemotherapeutic agent, its usage is limited owing to cardiotoxicity. Necroptosis is a new form of programmed cell death, and recent investigations indicated that necroptosis is vitally involved in serious cardiac pathological conditions. Dexrazoxane is the only cardiac protective drug approved by FDA for anthracycline. We aimed to explore whether and how dexrazoxane regulates doxorubicin-induced cardiomyocyte necroptosis. First, doxorubicin could cause heart failure and reduce cardiomyocyte viability by promoting cell apoptosis and necroptosis in vivo and in vitro. Second, necroptosis plays an important role in doxorubicin induced cardiomyocyte injury, which could be inhibited by Nec-1. Third, dexrazoxane increased cell viability and protect heart function by decreasing both cardiomyocyte apoptosis and necroptosis after doxorubicin treatment. Forth, dexrazoxane attenuated doxorubicin-induced inflammation and necroptosis by the inhibition of p38MAPK/NF-κB pathways. These results indicated that dexrazoxane ameliorates cardiotoxicity and protects heart function by attenuating both apoptosis and necroptosis in doxorubicin induced cardiomyocyte injury.

Abstract
OBJECTIVE To elucidate the function of miRNA-337 in the pathogenesis of diabetic nephropathy (DN) and its underlying mechanism. MATERIALS AND METHODS Type 2 diabetes db/db mice were assigned into db/db group, vehicle group, and si-miR group, and age-matched db/m mice were in the db/m group. Differences in mouse serum glucose, body weight, serum creatinine, and albumin/creatinine ratio (ACR) among the four groups were compared at 6 weeks, 10 weeks, 14 weeks, 18 weeks, and 22 weeks of age. The expression level of miRNA-337 in mouse kidney tissues was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Correlation between miRNA-337 expression with ACR was analyzed. Through Western blot analysis, protein levels of interleukin 6 (IL-6), IL-18, podocin, nephrin, and desmin in mouse kidney tissues were detected. RESULTS With the increasing age, serum glucose, body weight, serum creatinine, and ACR in db/db mice gradually increased, which were remarkably higher than age-matched db/m mice. After treatment with miRNA-337 inhibitor in db/db mice, no remarkable changes in serum glucose and body weight were found, while serum creatinine and ACR decreased. Compared with db/m mice, miRNA-337 expression in kidney tissues of db/db mice upregulated, which was positively correlated with ACR. Expression levels of IL-6 and IL-18 in kidney tissues of db/db mice increased relative to db/m mice, but they were downregulated by miRNA-337 inhibitor treatment. Moreover, podocin and nephrin downregulated, while desmin upregulated in kidney tissues of db/db mice than db/m mice. By miRNA-337 inhibitor treatment in db/db mice, levels of podocin and nephrin increased, whereas desmin level decreased. We obtained similar results at their cellular level. CONCLUSIONS We showed that miRNA-337 expression increases in db/db mice with diabetic nephropathy, which leads to podocyte injury by upregulating levels of IL-6 and IL-18.

Abstract
Objective: To study the clinical characteristics of outpatients with hand, foot and mouth disease (HFMD) caused by different serotypes of enteroviruses. Methods: This was a prospective study. From February 2017 to March 2018, 563 outpatients with HFMD were enrolled by systematic sampling in the Department of Infectious Diseases, Henan Children's Hospital. Throat swabs were collected to determine the serotypes via PCR. Demographic, clinical, and laboratory data were collected by standard questionnaire. All cases were followed up twice at 2 and 9 weeks after the initial outpatient visit through telephone interview. A total of 563 cases were enrolled and 555 (98.6%) cases were positive for human enteroviruses, including 338 (60.9%) males. Analyses were stratified by enterovirus serotypes, Chi square test or Fisher's exact test, Rank sum test was used for comparison among different groups. Results: The age of 555 cases was 24.2 (16.4, 41.3) months. Among them 44.0% (224 cases) were identified as coxsackievirus (CV)-A6, while 189 cases, 35 cases, 14 cases and 73 cases were identified as CV-A16, enterovirus (EV)-A71, CV-A10 and other serotypes, respectively. Fever (≥37.5 ℃) was present in 51.4% (285/555) of laboratory confirmed cases. The proportions of fever in cases of CV-A6 (68.9%(168/244)) and CV-A10 (12/14) were significantly higher than those in cases of CV-A16 (31.7%(60/189),χ(2)=57.344,14.313,both P=0.000), other serotypes (43.8%(32/73),χ(2)=15.101 and 8.242, P=0.000 and 0.004) and EV-A71 (37.1%(13/35), χ(2)=13.506 and 9.441, P=0.000 and 0.002) respectively. There was no significant difference between CV-A6 and CV-A10 in presentation of fever (χ(2)=1.785, P=0.182). There were 359 cases (64.7%) with eruptions in mouth, hands, feet and buttocks. Cases infected with EV-A71 had the highest proportions (74.3%(26/35)) of rash emerging simultaneously in mouth, hands, feet, and buttocks. The proportion in cases of CV-A16, CV-A6, CVA10 and other serotype were 73.5% (139/189), 61.9% (151/244), 7/14 and 49.3% (36/73), respectively. The proportion of rash on other parts of body, such as face, limbs or torso in cases infected with CV-A6 (16.8% (41/244)) was the higherest and the proportion in cases of CV-A16, EV-A71, CV-A10 or other serotypes were 8.5% (16/189) , 5.7% (2/35) , 1/14, 6.8% (5/73) , respectively. None of these cases developed serious complications. Desquamation occurred in 45.5% (179/393) cases 7.5 (5.0, 9.0) days after disease onset and 13.5% (53/393) cases showed onychomadesis 31.0 (18.0, 33.5) days after disease onset. The proportion of desquamation and onychomadesis associated with CV-A6 (64.2% (95/148) and 31.8% (47/148)) was significantly higher than CV-A16 (31.8% (49/154) and 1.3% (2/154), χ(2)=33.601 and 52.482, both P=0.000) and other serotypes (38.0%(19/50) and 6.0%(3/50),χ(2)=10.236 and 12.988, P=0.001 and 0.000). Desquamation appeared more in cases of CV-A6 than in cases of CV-A10 (2/11,χ(2)=9.386, P=0.002), with the proportion of onychomadesis higher in CV-A6 than in EV-A71 (3.3% (1/30),χ(2)=11.088, P=0.001). Conclusion: Clinical manifestation such as fever, rash emerging parts, desquamation and onychomadesis are different among outpatient HFMD cases infected with CV-A16, CV-A6, EV-A71, CV-A10 and other enteroviruses.

Abstract
With the rapid rising of global population, the demand for improving breeding techniques to greatly increase the worldwide crop production has become more and more urgent. Most researchers believe that the key to new breeding techniques lies in genetic improvement of crops, which leads to a large quantity of phenotyping spots. Unfortunately, current phenotyping solutions are not powerful enough to handle so many spots with satisfying speed and accuracy. As a result, high-throughput phenotyping is drawing more and more attention. In this paper, we propose a new field-based sensing solution to high-throughput phenotyping. We mount a LiDAR (Velodyne HDL64-S3) on a mobile robot, making the robot a "phenomobile." We develop software for data collection and analysis under Robotic Operating System using open source components and algorithm libraries. Different from conducting phenotyping observations with an in-row and one-by-one manner, our new solution allows the robot to move around the parcel to collect data. Thus, the 3D and 360° view laser scanner can collect phenotyping data for a large plant group at the same time, instead of one by one. Furthermore, no touching interference from the robot would be imposed onto the crops. We conduct experiments for maize plant on two parcels. We implement point cloud merging with landmarks and Iterative Closest Points to cut down the time consumption. We then recognize and compute the morphological phenotyping parameters (row spacing and plant height) of maize plant using depth-band histograms and horizontal point density. We analyze the cloud registration and merging performances, the row spacing detection accuracy, and the single plant height computation accuracy. Experimental results verify the feasibility of the proposed solution.

Abstract
Objective: To evaluate the effectiveness of rapid hepatitis B vaccination with different vaccine dosages and types in adults. Methods: Adults who were aged ≥20 years, negative in the detections of 5 HBV serum markers or only anti-HBc positive were selected from Chaoyang district of Beijing. They were divided into 4 community-based specific groups and given three doses of 10 μg HepB-SCY vaccine, 20 μg HepB-SCY vaccine, 20 μg HepB-CHO vaccine and 10 μg HepB-HPY vaccine respectively at month 0, 1, and 2. Their blood samples were collected within 1-2 months after completing the three dose vaccination to test anti-HBs level by using chemiluminesent microparticle immunoassay. A face to face questionnaire survey was conducted, and χ(2) test, Mantel- Haensel χ(2) test, Kruskal-Wallis rank test and multiple logistic regression analysis were performed. Results: A total of 1 772 participants completed vaccination and observation. Their average age was 48.5 years, and 62.75% of them were females. The anti-HBs positive rates in the groups of 10 μg HepB-SCY, 20 μg HepB-SCY, 20 μg HepB-CHO and 10 μg HepB-HPY vaccines were 79.49%, 84.34%, 82.50% and 74.15%, respectively (P=0.005), and the geometric mean titers (GMT) were39.53 mIU/ml, 62.37 mIU/ml, 48.18 mIU/ml and 33.64 mIU/ml respectively (P=0.025). The overall anti-HBs positive rate and GMT were 79.01% and 41.18 mIU/ml. The anti-HBs GMT of 4 groups declined with age. The differences in anti-HBs GMT among 4 groups minimized with age. The result of logistic modeling indicated that vaccine type and dosage, age and smoking were associated with anti-HBs statistically after controlling the variables of"only anti-HBc positive or not"and"history of hepatitis B vaccination". Conclusion: Hepatitis B vaccination at dosage of 20 μg based on 0-1-2 month rapid schedule could achieved anti-HBs positive rates>80% in middle aged and old people, which can be used as supplement of 0-1-6 month routine schedule.

Abstract
BACKGROUND To provide a scientific basis for the prevention and treatment of cervical cancer (CC), we investigated the distribution characteristics and genotypes of human papillomavirus (HPV) and the prevalence of multiple HPV infections in women of different ages seeking management for abnormal cytology in Foshan City. METHODS Screening for the 21 genotypes of HPV was carried out in 9945 females seeking management of abnormal cervical cytology results using rapid flow-through hybridization of nucleic acid molecules. The overall prevalence, genotype distribution and age-specific prevalence were examined. RESULTS Our results indicate that the prevalence of overall, high-risk, intermediate-risk, and low-risk HPV infections was 13.5%, 12.1%, 1.3%, and 1.9%, respectively. Of the 1346 women who tested positive, 89.5% were positive for a single HPV genotype, and 10.5% were positive for ≥2 genotypes. The most frequently detected HPV genotype was HPV-16 (2.9%), followed by HPV-52 (2.9%), HPV-58 (1.5%), and HPV-CP8304 (1.0%). The highest infection prevalence was found in patients 21-30 years old (271/1670, 16.2%). CONCLUSION The prevalence of HPV infection in women seeking management for abnormal cytology in Foshan City is highest in the younger population (21-30 years old). Similar to most previous surveys, HPV-58 and HPV-52 infections are as common as HPV-16 infection.

Abstract
AIM We aim to investigate the incidence and associated factors of vitamin D deficiency, a seldom reported factor, in patients with stages 1 and 2 chronic kidney disease (CKD) in southern China. METHODS We conducted a single-center observational study. Hospitalized patients over 14 years old, who were diagnosed with stages 1 and 2 CKD and had their serum 25-hydroxyvitamin D [25 (OH) D] measured, were included. Patients were divided into vitamin D deficient and non-deficient groups depending on the cutoff serum 25 (OH) D value of 37 nmol/L. Clinical and biochemical parameters were evaluated for associated factors of vitamin D deficiency by logistic regression. RESULTS A total of 118 patients were included, of which 62 (52.5%) were vitamin D insufficient and 47 (39.8%) were vitamin D deficient. Using multivariate binary logistic regression analysis, high serum level of gamma-glutamyl transpeptidase (GGT) (OR = 5.163; 95%CI, 1.105-24.130; P = 0.037), dyslipidemia (OR = 3.083; 95%CI, 1.029-9.243; P = 0.044), 24-hour urinary protein excretion (UPE) ≥3.5 g/24 hrs (OR = 5.010; 95%CI, 1.316-19.074; P = 0.018), and treatment with glucocorticoids (OR = 2.973; 95%CI, 1.093-8.084; P = 0.033) were independently associated with vitamin D deficiency. In addition, among different types of nephropathy, minimal change disease (MCD) had the highest incidence (85.7%) of vitamin D deficiency. CONCLUSION Poor vitamin D status is common in patients with stages 1 and 2 CKD in southern China. The incidence of vitamin D deficiency is 39.8%. High serum GGT level, dyslipidemia, 24-hour UPE ≥3.5 g/24 hrs, and treatment with glucocorticoids are independent associated factors of vitamin D deficiency.

Abstract
BACKGROUND AND OBJECTIVE The aim of this study was to explore the cellular mechanisms underlying gingipain-caused changes in cell morphology and apoptosis of osteoblasts. MATERIAL AND METHODS Human calvarial osteoblasts and mouse osteoblasts MC3T3-E1 were treated with gingipain extracts from Porphyromonas gingivalis stain W83. Apoptosis was detected with annexin V and propidium iodide flow cytometry analysis or terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling staining. F-actin was determined by immunostaining. Western blotting was used to detect protein expression. Knocking down and overexpressing approaches were used to determine the role of integrin β1. RESULTS Osteoblasts exposed to gingipain extracts displayed increased apoptosis, accompanied by loss of F-actin integrity and cell shrinkage. The effects of gingipain extracts were abolished by the cysteine protease inhibitor N-tosyl-l-lysyl chloromethyl-ketone. Notably, gingipain extracts resulted in reduction of integrin β1, accompanied by diminished active RhoA whereas without effect on the total RhoA. Knockdown of integrin β1 resembled those seen in gingipain-treated osteoblasts. By contrast, the effects of gingipain extracts were abrogated by either overexpression of integrin β1 or presence of RhoA agonist CN03. CONCLUSION Gingipain-induced F-actin disruption and apoptosis are mediated by the degradation of integrin β1 and inhibition of RhoA activity, which account for osteoblast apoptosis.

Abstract
Under traditional management on the Qinghai-Tibetan Plateau, yaks () graze only on natural pasture without supplements and are forced to cope with sparse forage of low N content, especially in winter. In contrast, indigenous Tibetan yellow cattle () require supplements during the cold season. We hypothesized that, in response to harsh conditions, yaks cope with low N intakes better than cattle. To test this hypothesis, a study of whole-body N retention and urea kinetics was conducted in 2 concurrent 4 × 4 Latin squares, with 1 square using yaks and 1 square using cattle. Four isocaloric forage-concentrate diets differing in N concentrations (10.3, 19.5, 28.5, and 37.6 g N/kg DM) were formulated, and by design, DMI were similar between species and across diets. Urea kinetics were determined with continuous intravenous infusion of NN urea for 104 h, and total urine and feces were concomitantly collected. Urea production, urea recycling to the gut, and ruminal microbial protein synthesis all linearly increased ( < 0.001) with increasing dietary N in both yaks and cattle. Urinary N excretion was less ( = 0.04) and N retention was greater ( = 0.01) in yaks than in cattle. Urea production was greater in yaks than in cattle at the 3 lowest N diets but greater in cattle than in yaks at the highest N diet (species × diet, < 0.02). Urea N recycled to the gut ( < 0.001), recycled urea N captured by ruminal bacteria ( < 0.001), and ruminal microbial protein production ( = 0.05) were greater in yaks than in cattle. No more than 12% of urea recycling was through saliva, with no difference between species ( = 0.61). Glomerular filtration rate was lower ( = 0.05) in yaks than in cattle. The higher urea recycling and greater capture of recycled urea by ruminal microbes in yaks than in cattle suggest that yaks use mechanisms to utilize dietary N more efficiently than cattle, which may partially explain the better survival of yaks than cattle when fed low-N diets.

Abstract
Objective: To analyze the clinical characteristics and prognosis of implanting drug-eluting stents (DES) for unprotected left main (ULM) coronary artery disease patients with left ventricular systolic dysfunction (LVSD). Methods: A total of 511 ULM coronary artery disease patients who underwent DES implantation from January 2005 to January 2012 in Department of Cardiology, Beijing Anzhen Hospital were included in the study. Based on left ventricular ejection fraction (LVEF), the patients were divided into three groups: LVEF≤40% (n=104), 41%≤LVEF≤49% (n=137), and LVEF≥50% (n=270). The clinical characteristics of patients undergoing DES implantation were retrospectively compared, and the effects of LVSD on ULM coronary artery disease were analyzed. Results: After comparison of clinical baseline data among three different LVEF groups, the incidence of peripheral vascular diseases, old myocardial infarction (OMI), multi-vessel lesions, complete revascularization and chronic total occlusion (CTO) was statistically different (P=0.002, P<0.001, P<0.001, P=0.049, P=0.001, respectively). However, there was no significant difference in the incidence of other clinical characteristics (all P>0.05). In terms of survival analysis, total mortality and cardiac mortality were both remarkably higher in LVEF≤40% group than those in LVEF≥50% group (both P<0.001). There was no statistical difference of total mortality between 41%≤LVEF≤49% group and LVEF≥50% group (P>0.05), while cardiac mortality was higher in LVEF≥50% group (P=0.027) . Besides, there was no significant difference among three groups in major adverse cardiac and cerebral events (MACCE), myocardial infarction(MI), cerebral infarction and target vessel revascularization (TVR) (all P>0.05). After adjusting for multiple clinical factors, total mortality and cardiac mortality were both remarkably higher in LVEF≤40% group than those in LVEF≥50% group (P=0.002, P<0.001), while there were no statistical differences of total mortality and cardiac mortality between 41%≤LVEF≤49% group and LVEF≥50% group (both P>0.05). In terms of MACCE, MI, cerebral infarction and TVR, there were also no significant differences among three groups (all P>0.05). Conclusion: For ULM coronary artery disease patients with LVSD, implanting DES is safe and effective, but for those with severe LVSD (LVEF≤40%), DES implantation showed an increased risk of long-term death and therefore should be selected with great care.

Abstract
State observer is an essential component in computerized control loops for greenhouse-crop systems. However, the current accomplishments of observer modeling for greenhouse-crop systems mainly focus on mass/energy balance, ignoring physiological responses of crops. As a result, state observers for crop physiological responses are rarely developed, and control operations are typically made based on experience rather than actual crop requirements. In addition, existing observer models require a large number of parameters, leading to heavy computational load and poor application feasibility. To address these problems, we present a new state observer modeling strategy that takes both environmental information and crop physiological responses into consideration during the observer modeling process. Using greenhouse cucumber seedlings as an instance, we sample 10 physiological parameters of cucumber seedlings at different time point during the exponential growth stage, and employ them to build growth state observers together with 8 environmental parameters. Support vector machine (SVM) acts as the mathematical tool for observer modeling. Canonical correlation analysis (CCA) is used to select the dominant environmental and physiological parameters in the modeling process. With the dominant parameters, simplified observer models are built and tested. We conduct contrast experiments with different input parameter combinations on simplified and un-simplified observers. Experimental results indicate that physiological information can improve the prediction accuracies of the growth state observers. Furthermore, the simplified observer models can give equivalent or even better performance than the un-simplified ones, which verifies the feasibility of CCA. The current study can enable state observers to reflect crop requirements and make them feasible for applications with simplified shapes, which is significant for developing intelligent greenhouse control systems for modern greenhouse production.

Abstract
OBJECTIVE To study the relationship between surface markers of CD56 and CD19 and karyotypes and prognosis in multiple myeloma. METHODS A total of 126 cases of newly diagnosed multiple myeloma in the first hospital of Peking university from 2011 to 2015 were enrolled in this study. Cytogenetic abnormalities and immunophenotypes were detected by using fluorescence in situ hybridization and flow cytometry respectively before chemotherapy. Bone marrow smear was used for detection of abnormal plasma cell infiltration. By combining with their basic data, the relationship between immunophenotypes, cytogenetics and prognosis of MM was analyzed. RESULTS (1) The median of myeloma cells in the 126 patients was 0.24(0.01-0.97); the median of myeloma cells in 116 patients who have immunophenotype datas was 0.25(0.01-0.97); the median of myeloma cells in CD19 positive patients was 0.11(0.01-0.53); the median of myeloma cells in CD19 negative patients was 0.26(0.01-0.97). The median of myeloma cells in CD19 positive patients was much lower than that in CD19 negative patients(P=0.036). (2)In 116 patients detected by the immunophenotype, the myeloma cells expressed CD19,CD20,CD56 and CD117. Compared with CD56 negative patients(45/116,38.79%),CD56 positive patients(71/116,61.21%) had a clearly favorable disease outcome(OS was 53.0 month vs 31.0 month,P=0.016; PFS was 37.5 months vs 18.4 months, P=0.036). (3)CD19 positive patients was 16.38%(19/116),CD19 negative patients was 83.62%(97/116); CD19 positive MM and CD19 negative MM had no difference in OS and PFS. (4)CD117 positive rate in CD19 positive patients was 42.11%(8/19), the CD117 positive rate in CD19 negative patients was 18.57%(18/97), the CD19 expression positively correlated with CD117 expression. (5)FISH detection was done for 67 newly diagnosed MM patients, 8 patients showed normal karyotypes(11.94%), 59 patients had abnormal karyotypes(88.06%). The most common abnormal karyotypes were IgH rearragement which occurred in 47 patients(70.15%). Other abnormal karyotypes included 1q21+, del(13q14),del(13q14.3),del(17p13) . These abnormal karyotypes occurred in 37 patients(55.22%),31 patients(46.27%),33 patients(49.25%) and 13 patients(19.40%) respectively. In comparison with CD19 negative MM patients, the incidence rate of 1q21+ and del(13q14.3) was significantly lower in CD19 positive patients(1q21+:33.33% vs 61.54%,P=0.016; del(13q14.3): 33.33% vs 53.85%,P=0.043). CONCLUSION The prognosis of CD56 positive MM patients is better than that of CD56 negative MM patients, CD19 negative MM has more abnormal karyotypes and bone marrow infiltration,but they have no statistical prognostic differences.

Abstract
OBJECTIVE To evaluate the clinical features, treatment and prognosis of Eosinophilic Granulomatous Vasculitis. METHODS We analyzed retrospectively the clinical and laboratory features, treatment and prognosis of 43 patients with Eosinophilic Granulomatous Vasculitis who admitted to the Department of Rheumatology of the First Affiliated University Hospital of Sun Yat-sen University between 2005 and 2014. RESULTS Of the 43 patients, 31 patients (72.1%) had allergic symptoms in the disease course and 16 patients (37.2%) had asthma and lung wheezing sound when performing the physical examination.Organs involvements included skin, acra, lung, kidney, central and peripheral nervous system, digestive system and heart.Positive antineutrophilic cytoplasmic antibody (ANCA) which mainly with MPO-ANCA was found in 18 patients (41.9%). Thirty-nine patients (90.7%)had high blood eosinophil level while all patients (100%) had elevated IgE.Two patients died of multiple organ failure in their acute phase, and the others had favorable prognosis after receiving the treatment of glucocorticoid combine with cyclophosphamide or methotrexate. CONCLUSIONS Eosinophilic Granulomatous Vasculitiscould make damage to organs and tissues.Only 72.1% patients had allergic symptoms and 37.2% patients had asthma and lung wheezing sound.More than half patients have the negative ANCA.Glucocorticoidcombine with cyclophosphamide or methotrexate can achieve satisfactory therapeutic effects.

Abstract
BACKGROUND Spinal cord stimulation (SCS) has been shown to be effective in the management of certain neuropathic pain conditions, however, the underlying mechanisms are incompletely understood. In this study, we investigated repetitive SCS in a rodent neuropathic pain model, revealing long-lasting and incremental attenuation of hyperalgesia and a mechanism of action involving endocannabinoids. METHOD Animals were implanted with monopolar electrodes at the time of partial sciatic nerve injury. Dorsal columns at spinal segments T12/13 were stimulated 3 days later (early SCS), and again at day 7 (late SCS) using low-frequency parameters. Hypersensitivity to cutaneous mechanical stimuli was assessed using von Frey filaments. Pharmacological agents, selected to identify endocannabinoid and opioid involvement, were administered intraperitoneally, 10 min before SCS. RESULTS Early SCS caused partial reversal of mechanical hypersensitivity with corresponding changes in the biomarker of central sensitization, [phospho-Tyr1472 ]-GluN2B. The partial reversal of hyperalgesia by early SCS was amplified by co-administration of LY 2183240, an inhibitor of endocannabinoid reuptake/breakdown. This amplification was inhibited by a CB1 R antagonist, AM251, but not by a CB2 R antagonist, AM630. Early SCS-induced reversal of hyperalgesia was attenuated by naloxone, indicating a role for opioids. Late SCS resulted in an incremental level of reversal of hyperalgesia, which was inhibited by AM251, but not by CB2 or opioid receptor antagonists. CONCLUSION The endocannabinoid system, and in particular the CB1 R, plays a pivotal role in the long-lasting and incremental reversal of hyperalgesia induced by repetitive SCS in a neuropathic pain model. SIGNIFICANCE Alternative parameters for repetitive spinal cord stimulation (SCS) at 25/10 Hz elicit particularly long-lasting and incremental reversal of hyperalgesia in a neuropathic pain model through a mechanism involving endocannabinoids.
