Abstract
Subsurface runoff represents the main pathway of nitrate transport in hilly catchments. The magnitude of nitrate export from a source area is closely related to subsurface hydrological connectivity, which refers to the linkage of separate regions of a catchment via subsurface runoff. However, understanding of how subsurface hydrological connectivity regulates catchment nitrate export remains insufficient. This study conducted high-frequency monitoring of shallow groundwater in a hilly catchment over 17 months. Subsurface hydrological connectivity of the catchment over 38 rainfall events was analyzed by combining topography-based upscaling of shallow groundwater and graph theory. Moreover, cross-correlation analysis was used to evaluate the time-series similarity between subsurface hydrological connectivity and nitrate flux during rainfall events. The results showed that the maximum subsurface hydrological connectivity during 32 out of 38 rainfall events was below 0.5. Although subsurface flow paths (i.e., the pathways of lateral subsurface runoff) exhibited clear dynamic extension and contraction during rainfall events, most areas in the catchment did not establish subsurface hydrological connectivity with the stream. The primary pattern of nitrate export was flushing (44.7%), followed by dilution (34.2%), and chemostatic behavior (21.1%). A threshold relationship between subsurface hydrological connectivity and nitrate flux was identified, with nitrate flux rapidly increasing after the subsurface connectivity strength exceeded 0.121. Moreover, the median value of cross-correlation coefficients reached 0.67, which indicated subsurface hydrological connectivity exerts a strong control on nitrate flux. However, this control effect is not constant and it increases with rainfall amount and intensity as a power function. The results of this study provide comprehensive insights into the subsurface hydrological control of catchment nitrate export.

Abstract
Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

Abstract
Anthropogenic activities alter the underlying surface conditions and arrangements of landscape features in a drainage basin, interfering with the pollutant (e.g., dissolved nitrogen, phosphorus) transport network configuration and altering the hydrological response. Assessing the impact of anthropogenic activities on hydrological connectivity for natural-artificial catchment is critical to understand the hydrological-driven ecosystem processes, services and biodiversity. However, quantifying this impact at catchment scale remains challenging. In this study, a new framework was proposed to quantify the impact of anthropogenic activities on hydrological connectivity combined with graph theory and network analysis. This framework was exemplified in a natural-artificial catchment of the Yangtze River basin of China. Based on remote sensing and field-investigated data, three transport networks were constructed, including natural transport network (N1), ditch-road transport network (N2), and terrace-dominated transport network (N3), which reflected the different human intervention. The results showed that human intervention improved the connectivity of the nodes and enhanced the complexity of the catchment transport network structure. Anthropogenic activities significantly decreased the hydrological structural connectivity of the catchment. In particular, compared with the N1 network, the critical nodes for hydrological connectivity which were judged by connectivity indexes were reduced by 92.94% and 95.29% in the N2 and N3 network, respectively. Furthermore, the ditch-road construction had a greater impact than terraces in decreasing hydrological structural connectivity at catchment scale. This framework has proven effective in quantifying the hydrological connectivity analysis under different human intervention at the catchment scale and facilitates the improvement of catchment management strategies.

Abstract
As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a common inflammatory disease in otolaryngology, mainly manifested as nasal congestion, nasal discharge, facial pain/pressure, and smell disorder. CRS with nasal polyps (CRSwNP), an important phenotype of CRS, has a high recurrence rate even after receiving corticosteroids and/or functional endoscopic sinus surgery. In recent years, clinicians have focused on the application of biological agents in CRSwNP. However, it has not reached a consensus on the timing and selection of biologics for the treatment of CRS so far. SUMMARY We reviewed the previous studies of biologics in CRS and summarized the indications, contraindications, efficacy assessment, prognosis, and adverse effects of biologics. Also, we evaluated the treatment response and adverse reactions of dupilumab, omalizumab, and mepolizumab in the management of CRS and made recommendations. KEY MESSAGES Dupilumab, omalizumab, and mepolizumab have been approved for the treatment of CRSwNP by the US Food and Drug Administration. Type 2 and eosinophilic inflammation, need for systemic steroids or contraindication to systemic steroids, significantly impaired quality of life, anosmia, and comorbid asthma are required for the use of biologics. Based on current evidence, dupilumab has the prominent advantage in improving quality of life and reducing the risk of comorbid asthma in CRSwNP among the approved monoclonal antibodies. Most patients tolerate biological agents well in general with few major or severe adverse effects. Biologics have provided more options for severe uncontrolled CRSwNP patients or patients who refuse to have surgery. In the future, more novel biologics will be assessed in high-quality clinical trials and applied clinically.

Abstract
The dissolved carbon concentration, which is responsible for aquatic ecosystem productivity and water quality, is tightly coupled with hydrological processes. Excess dissolved carbon may exacerbate eutrophication and hypoxia in aquatic ecosystems and lead to deterioration of water quality. Storm events dominate the dynamics of dissolved carbon concentrations, and this nonlinear behavior exhibits significant time scale dependence. Here, we identified inter- and intra-event variability in the dissolved carbon concentration-discharge (C-Q) relationship in an agriculture-intensive catchment. The driving factors of C-Q hysteresis patterns for dissolved inorganic carbon (DIC) and organic carbon (DOC) were quantified by redundancy analysis combined with hierarchical partitioning. At the inter-event scale, DIC exhibited mainly clockwise hysteresis, indicating an exhaustible, proximal source (e.g., groundwater). However, DOC hysteresis was generally counter-clockwise, indicating distal and plentiful sources (e.g., soil water) in the agricultural catchment. Hierarchical partitioning showed that total rainfall, peak discharge and flood intensity explained 28.38% of the total variation in C-Q hysteresis for DIC and 39.87% for DOC at the inter-event scale. At the intra-event scale, time series analysis of dissolved carbon concentration and discharge indicated the interconversion of supply limitation to transport limitation, which depends on the activation of the specific DIC or DOC source zones. These findings provide significant insights into understanding the dynamics of dissolved carbon during storm periods and are important for targeted watershed management practices aimed at reducing carbon loading to surface waters.

Abstract
Neonicotinoids pollution poses a serious threat to aquatic ecosystems. However, there is currently little knowledge about how neonicotinoids are transferred from the agricultural environment to the aquatic environment. Here, we conducted in situ high-frequency monitoring of neonicotinoids in soil-water systems along the hydrological flow path during rainfall to explore the horizontal and vertical transport mechanisms of neonicotinoids. The collected samples included 240 surface runoff, 128 subsurface runoff, 60 eroded sediment, 120 soil and 144 soil solution, which were used to analyse neonicotinoids concentrations. Surface runoff, subsurface runoff and eroded sediment were the three main paths for the horizontal migration of neonicotinoids. In the CK (citrus orchards without grass cover) and grass-covered citrus orchards, there are 15.89% and 2.29% of the applied neonicotinoids were transported with surface runoff, respectively. While in the CK and grass-covered citrus orchards, there are only 1.23% and 0.19% of the applied neonicotinoids were transported with eroded sediment and subsurface runoff. Although the amount of neonicotinoids lost along with eroded sediment was small, the concentration of neonicotinoids in eroded sediment was two orders of magnitude higher than the concentration of neonicotinoids in sediments of the surface water. Meanwhile, neonicotinoids migrated vertically in soil due to water infiltration. In the CK and grass-covered citrus orchards, there are 57.64% and 24.36% of the applied neonicotinoids were retained in soil and soil solution, respectively, and their concentration decreased as soil depth increased. Another noteworthy phenomenon is that more neonicotinoids migrated to deeper soil layers under grass cover compared with no grass cover because grass roots promoted the formation of cracks and vertical preferential flow. Our results are expected to improve the accuracy of neonicotinoids pollution prediction by considering migration paths, including surface and subsurface runoff and eroded sediment.

Abstract
Objective: To investigate the Helicobacter pylori (H. pylori) eradication rate and improvement of dyspepsia in patients who were newly diagnosed with H. pylori infection and dyspepsia and treated by bismuth-containing quadruple therapy followed by Jing-Hua-Wei-Kang(JHWK). Methods: Patients who were newly diagnosed with dyspepsia and H. pylori infection and treated in 16 medical centers in China between December 1, 2017 and September 30, 2019 were randomly divided into two groups. The experimental group received bismuth-containing quadruple therapy (esomeprazole+amoxicillin+furazolidone+colloidal bismuth pectin capsule, 14 days), followed by JHWK (30 days), and the course of treatment was 44 days in total. In the control group, the administration regimen was bismuth-containing quadruple therapy (esomeprazole+amoxicillin+furazolidone+colloidal bismuth pectin capsule, 14 days). The main outcome measure was H. pylori eradication rate, while the secondary outcome measures were dyspepsia symptom changes and adverse events during the treatment and the 1st month after treatment. Results: A total of 1 054 patients were included in the study. There were 522 cases enrolled in the experimental group, including 224(42.91%) men and 298(57.09%) women, and the age was 53(26, 73) years old; 532 cases enrolled in the control group, including 221(41.54%) men and 311(58.46%) women, and the age was 46(22, 71) years old. Based on PP analysis, it was found that the H. pylori eradication rate in the experimental group was significantly higher than those in the control group (93.85% vs 87.88%, P=0.001). In the group of all enrolled patients, the symptom dyspepsia after H. pylori eradication was significantly improved compared with that before treatment [4(4, 7) vs 15(10, 22), P<0.001], so was the superior and middle abdominal pain [1(1, 4) vs 4(1, 8), P<0.001], the postprandial fullness [1(1, 4) vs 4(4, 9), P<0.001], the early satiety [1(1, 1) vs 4(1, 4), P<0.001], and the heartburn [1(1, 1) vs 1(1, 4), P<0.001]. The symptom dyspepsia after treatment was significantly improved compared with that before treatment in the experimental, the control groups, the successful and the unsuccessful H. pylori eradication groups. The superior and middle abdominal pain after treatment was signifcantly improved than that before treatment [1(1, 2) vs 1(1, 4), P<0.001], so were the postprandial fullness [1(1, 3) vs 1(1, 4), P=0.002] and the dyspepsia[4(4, 7) VS 7(4, 10), P<0.001]. There was no statistically significant difference in the incidence of adverse events between the experimental group and the control group (1.34% vs 0.38%, P=0.09). Conclusions: Compared with bismuth-containing quadruple therapy, bismuth-containing quadruple therapy followed by JHWK significantly improves the H. pylori eradication rate without increasing the incidence of adverse events. H. pylori eradication therapy can improve symptoms of patients with H. pylori infection and dyspepsia.

Abstract
Sensorineural hearing loss (SNHL) is a common causes of disability. Neural stem cells (NSCs) from the cochlear nuclei have been considered to be a potential direction for the treatment of SNHL. Neuregulin 1 (NRG1)/ErbB2 signaling displays an essential role in nervous system development. In this study, we aimed to explore the roles of NRG1/ErbB2 in differentiation and apoptosis of cochlear nuclei NSCs. The data showed that the expression of NGR1 and ErbB2 in cochlear nuclei NSCs isolated from rats were increased with the age of rats. NRG1 treatment reduced the nestin-positive cells number, increased the MAP2-positive and GFAP-positive cells number, decreased the expression of cleaved-caspase-3, and increased the activation of PI3K/AKT. ErbB2 knockdown by lentiviral-mediated ErbB2 shRNA infection reversed the effect of NRG1 on cochlear nuclei NSCs. LY294002 administration further enhanced the effect of ErbB2 silencing on the expression of nestin, MAP2, GFAP and cleaved-caspase-3. Taken together, NRG1/ErbB2 regulates differentiation and apoptosis of cochlear nucleus NSCs through PI3K/Akt pathway.

However, the relationship between the watershed characteristics and nitrogen and phosphorus concentrations in reservoir bays is poorly understood. We selected 66 bays from the Danjiangkou Reservoir and sampled twice per year (storage and discharge periods) from 2015 to 2018 to monitor the total nitrogen (TN) and total phosphorus (TP) concentration in the waterbodies of the reservoir bays. Four types of watershed characteristic indices (topographic variables, soil variables, land-use composition, and landscape patterns) around these bays were obtained. We quantified the relationship between the TN and TP concentrations and watershed characteristics in the waterbodies of the reservoir bays using partial least squares regression (PLSR). The results showed that the mean concentrations of TN and TP in the storage period (TN:1.69 mg·L-1, TP:0.088 mg·L-1) were higher than those in the discharge period (TN:1.22 mg·L-1, TP:0.063 mg·L-1). The optimal PLSR models explained 67.9% and 82.5% of the TN concentration variability, and 65.4% and 67.2% of the TP concentration variability during the storage and discharge period, respectively. Based on the variable importance in the projection (VIP) values, soil erodibility had significant effects on the TN and TP concentrations. The key factors affecting the TN concentration were the slope gradient, basin relief, topographic wetness index, forest and agricultural land use, whereas the factors controlling the TP concentration were the landscape shape index, edge density, Shannon's diversity index and grass land use, although the TP concentration was also controlled by the patch density and contagion during the storage period, and by mean patch size and largest patch index during the discharge period. This study provides critical insights into sustainable landscape planning and effective reservoir water quality management.

Abstract
Whether channel erosion or topsoil erosion constitutes the dominant erosion process throughout in the hilly region of the Chinese Loess Plateau (CLP), which suffers perhaps the most severe soil erosion in the world, had been controversial for a long time. The present article attempts to use the mid-infrared (MIR) spectroscopy fingerprinting method to trace sediment sources within nine small catchments in the hilly region of the CLP. Two major categories of sediment sources are identified: channel sediment and topsoil. Sediments trapped by check dams are used as the final sediment transferred by soil erosion. Discriminant analysis shows that MIR spectroscopy can differentiate between the two kinds of source sediments very well. The contributions of channel sediment and topsoil to the total final sediment are quantified using partial least squares regression (PLSR) analyses of MIR spectra to compare the trapped sediment samples with experimental models. The results of the root mean square error of calibration, root mean square error of validation and coefficient of determination for 18 models all show that the MIR-PLSR models boast very high prediction abilities in the nine catchments. A comparison between the geochemical fingerprinting method and the MIR spectroscopy method in one catchment reveals that although the two methods agree well on the channel sediment contributions, the two methods produce a significant difference (R2 = 0.4). Overall, the MIR-PLSR results show that channel sediments contribute 19% to 66% of the total sediment with an average of 33 ± 16% in the nine small catchments. Our results indicate that although channel bank sediment is important, topsoil erosion is the predominant process in small dam-controlled catchments on the CLP. Furthermore, the MIR spectroscopy fingerprinting method can provide a useful, non-destructive, rapid and inexpensive tool for tracing sediment sources from different kinds of loess.

Abstract
Objective: To compare the outcomes of gastrectomy with either wedge resection of the pancreas or pancreaticosplenectomy for adenocarcinoma of the esophagogastric junction (AEG) invading pancreas. Methods: From May 2005 to December 2015, a total of 64 patients with AEG invading pancreas underwent gastrectomy with either wedge resection of pancreas (n=25) or pancreaticosplenectomy (n=39) at Department of Thoracic Surgery, Fourth Hospital, Hebei Medical University. There were 53 males and 11 females, with a mean age of 60.2 years (range: 39 to 77 years). According to the AJCC esophageal cancer staging system, 8(th) edition, there were 27 patients in phase T4N0M0, 18 in phase T4bN1M0, 9 in phase T4bN2M0 and 10 in phase T4bN3M0. Follow-up was carried out every 6 months. The t-test for the measurement data and the χ(2) test, Fisher exact test or Wilcoxon ran-sum test for the enumeration data were used between the two groups. Survival curves were generated using the Kaplan-Meier method, and compared using the Log-rank test. Multivariate analysis was undertaken using the Cox proportional hazard model (forward stepwise regression). Results: In 39 patients who underwent pancreaticosplenectomy, incision infection occurred in 5 patients, anastomotic leak, peritoneal infection, lung infarction each occurred in 1 patient. There was 1 respiratory failure and 1 peritoneal infection in 25 patients undergoing wedge resection of the pancreas. There were no significant difference in the incidence of postoperative complications between the 2 groups (8/39 vs. 2/25, P=0.292), and no postoperative death in the study. Fifty-seven patients were followed up, with a follow-up rate of 89.1%. The 5-year overall survival rate was 32.3% in patients who underwent simultaneous gastrectomy and pancreaticosplenectomy, compared to 0 in those who underwent gastrectomy and wedge resection of the pancreas (χ(2)=4.484, P=0.034). The 5-year overall survival rate for patients who undergoing adjuvant chemotherapy was 32.3%, compared to 17.2% in whom underwent surgery alone (χ(2)=4.186, P=0.041). Conclusions: Survival benefit from R0 resection by simultaneous gastrectomy and pancreaticosplenectomy for AEG invading the pancreas can be achieved. Adjuvant chemotherapy is necessary for these patients.

Abstract
This paper aims to investigate the hydrological response of a large-scale (8973 km2) mountainous watershed to different rainstorm spatial patterns and reforestation. Based on 32 years of observations, measurements of 184 rainstorm events and 125 sediment-producing events with complete hydrographs were analyzed. The K-means clustering method was used to classify the spatial patterns of rainstorm events in accordance with their event-based spatial rainfall characteristics. The 184 rainstorm events were classified into four spatial patterns, among which the spatial features differ significantly: (I) Spatial Pattern I (SPI) includes rainstorms with a low amount of cumulative areal rainfall (27.4 mm), the highest spatial variability (0.986), and the highest frequency; (II) Spatial Pattern II (SPII) includes rainstorms of high spatial variability (0.759) and the largest amount of local maximum daily rainfall (106.8 mm); (III) Spatial Pattern III (SPIII) includes rainstorms with a medium amount of cumulative areal rainfall (58.7 mm) and low spatial variability (0.362); and (IV) Spatial Pattern IV (SPIV) includes rainstorms with the largest amount of cumulative areal rainfall (117.2 mm) and the lowest spatial variability (0.313). Vegetation cover in the upper Du watershed was significantly improved after the implementation of the Grain-for-Green project. The average area-specific sediment yields (SSY) for the four SPs were 15.4, 65.5, 55.8, and 286.2 t km-2 before reforestation and decreased to 6.0, 59.3, 43.7 and 89.9 t km-2, respectively, after reforestation. ANOVA (analysis of variance) indicated that reforestation resulted in a significant reduction in runoff coefficient under SPIII and SPIV and a significant reduction in SSY under SPI and SPIV. A hysteresis analysis suggested that the proportion of events with a clockwise loop increased from 64.9% before reforestation to 82.1% after reforestation and that complex loops became less common during 2000-2010 under SPIV, thereby implying a reduced sediment supply.

Abstract
Increasing evidences indicate that dys-regulation of MicroRNAs contributes to hepatocellular carcinoma. However, the roles of miR-485-5p in HCC are still largely unexplored. In the present study, our quantitative real-time PCR analysis found that miR-485-5p was significantly down-regulated in 50 pairs of human HCC tissues. Moreover, the reduced expression of miR-485-5p was significantly correlated with larger tumor size and more tumor number in patients with HCC. In vitro studies further showed that overexpression of miR-485-5p mimics could inhibit, while its antisense oligos promote cell proliferation and invasion. Results from the dual-luciferase reporter gene assays and western blot further showed that stanniocalcin 2 was a direct target of miR-485-5p. Therefore, our data suggest a novel role for miR-485-5p in the regulation of HCC progression.

Abstract
Nucleotide-binding oligomerization domain-containing protein-1 (NOD1) is a cytoplasmic pattern recognition receptor (PRR) and a key member of the NOD-like receptor (NLR) family. It has been reported that NLRs recognize a variety of microbial infections to induce the host innate immune response via modulation of NF-κB signaling. However, no reports on chicken NOD1 have been reported to date. In the current study, the full-length cDNA sequence of NOD1 was cloned. The complete open reading frame of NOD1 contains 2856 bp and encodes a 951 amino acid protein. Structurally, it is comprised of one caspase recruitment domain at the N-terminus, seven leucine-rich repeat regions at the C-terminus, and one NACHT domain between the N and C-termini. Phylogenetic analyses showed that chicken NOD1 clusters with duck and turkey. Furthermore, tissue-specific expression analyses of chicken NOD1 were performed using quantitative reverse transcription-PCR. NOD1 is widely distributed in various tissues, with the highest expression observed in testes. Finally, induced expression of chNOD1 and its associated adaptor molecule receptor-interacting protein 2, as well as the effector molecule NF-κB, was observed following S. enterica serovar Enteritidis infection. These findings highlight the important role of chicken NOD1 in response to pathogenic invasion. The present study is the first report of the cloning, expression, and functional analysis of chicken NOD1 and provides the foundation for future research on the structure and function of chicken NOD1.

Abstract
INTRODUCTION Whether the incidence rate of deep venous thrombosis (DVT) between laparoscopic and open colorectal cancer surgery the same or not were under the debated without conclusion. The aim of this study was to compare the incidence of DVT after laparoscopic or open colorectal cancer surgery by meta-analysis. MATERIALS AND METHODS The open published articles comparing the incidence of DVT after laparoscopic or open colorectal cancer were collected in the data bases of Medline, the Cochrane central register of controlled trials and CNKI. The relative risk (RR) was pooled by using random or fixed effect mode to evaluate the incidence of DVT between laparoscopic or open colorectal cancer surgery. RESULTS After searching the databases, 9 randomized clinical studies with 2606 colorectal cancer cases were included in this meta-analysis. The mean operation time was 201.8 ± 17.28 min with its range of 180.0-224.4 min in the laparoscopic surgery group and 148.1 ± 18.8 min with its range of 135.0-184.0 min in the open surgery group. The operation time for laparoscopic surgery group were significant lower than in the open surgery group (P < 0.05). The RR of DVT between the laparoscopy and open surgery groups was 0.71 with its 95% confidence interval of 0.35-1.45 (P = 0.35). CONCLUSIONS The operation time in laparoscopic colorectal cancer surgery was statistical longer than in the open colorectal cancer surgery, but the DVT risk of the two surgery approach was not different according to this meta-analysis.

Abstract
Rhynchophorus ferrugineus (Coleoptera, Curculionidae) is the most destructive pest of palm trees worldwide containing it invasive areas, such as the southern part of China. It is always emphasized to develop integrated pest management based on biological agents, but their success is not very exciting. Presently, the immune defenses of this pest against biological agents attract scarce attention. It is still unclear whether immune priming also generally occurs in insect pests and in response to different pathogens. Our results indicated that previous challenge of bacteria pathogen enhanced the magnitude of phenoloxidase activity and antibacterial activity in R. ferrugineus larvae against the secondary infection. Furthermore, trans-generational immune priming was also determined in this pest, and only challenged R. ferrugineus mothers transferred the immune protection to their offspring which suggested males and females of this pest might have evolved different strategies on the investment of delivering immune protection to their offspring. Importantly, our data provide the evidence to suggest that different kinds of biological control agents might be used alternatively or in combination to fight against R. ferrugineus because of the existence of immune priming with low species-specific level. On the other hand, for this invasive pest, the immune priming may also facilitate its adaptation and dispersal in the new regions.

Abstract
This study was an attempt to analyse the regional environmental quality with the application of remote sensing, geographical information system, and spatial multiple criteria decision analysis and, to project a quantitative method applicable to identify the status of the regional environment of the study area. Using spatial multi-criteria evaluation (SMCE) approach with expert knowledge in this study, an integrated regional environmental quality index (REQI) was computed and classified into five levels of regional environment quality viz. worse, poor, moderate, good, and very good. During the process, a set of spatial criteria were selected (here, 15 criterions) together with the degree of importance of criteria in sustainability of the regional environment. Integrated remote sensing and GIS technique and models were applied to generate the necessary factors (criterions) maps for the SMCE approach. The ranking, along with expected value method, was used to standardize the factors and on the other hand, an analytical hierarchy process (AHP) was applied for calculating factor weights. The entire process was executed in the integrated land and water information system (ILWIS) software tool that supports SMCE. The analysis showed that the overall regional environmental quality of the area was at moderate level and was partly determined by elevation. Areas under worse and poor quality of environment indicated that the regional environmental status showed decline in these parts of the county. The study also revealed that the human activities, vegetation condition, soil erosion, topography, climate, and soil conditions have serious influence on the regional environment condition of the area. Considering the regional characteristics of environmental quality, priority, and practical needs for environmental restoration, the study area was further regionalized into four priority areas which may serve as base areas of decision making for the recovery, rebuilding, and protection of the environment.

Abstract
Recent studies report that a conflict between information from the visual system and vestibular system is one of the main reasons for induction of motion sickness (MS). We may be able to clarify the integration mechanism of visual and vestibular information using an animal model with a visual defect, the retinal degeneration fast (rdf) mouse, and the role of vestibular information in the pathogenesis of MS. The rdf mice and wild-type Kunming mice were subjected to rotary stimulation to induce MS. Conditioned taste anorexia to saccharin solution and behavior score were used to observe the differences in MS sensitivity between two types of mice. The decrease in intake of saccharin solution and the behavior score in rdf mice were greater than those in normal mice. After rotatory stimulation, the reduction of intake mass and the behavior score were greater in rdf mice compared to those of normal mice. The rdf mice were more sensitive to rotation than normal mice. We conclude that visual information plays a role in the pathogenesis of MS. Visual information and vestibular information impact each other and integrate through certain channels in the central nervous system in mice.

Abstract
Hearing loss is a leading cause of disability in China. However, the research status in the field of hearing among Chinese individuals in the three major regions of China: Mainland (ML), Hong Kong (HK) and Taiwan (TW), are unknown. The output of hearing articles published in international otorhinolaryngology journals from these three regions were compared in this study. Articles published in 31 international otorhinolaryngology journals related to hearing originating from the ML, TW and HK from 2000 to 2011 were retrieved from the PubMed database search. The number of total articles, clinical trials, randomized controlled trials, case reports, and articles published in the top 5 international otorhinolaryngology journals were assessed in terms of quantity and quality comparisons. The total number of articles from the three regions increased significantly from 2000 to 2011. There were 379 articles from ML (143), TW (180) and HK (56) in the past 10 years. The number of articles published per year from the ML has exceeded those from TW in 2009 and HK in 2003. TW had the most articles (46) published in the top 5 international otorhinolaryngology journals among the three regions. The total number of articles from the three major regions of China increased significantly from 2000 to 2011. The numbers of articles published per year from the ML have exceeded those from TW and HK. However, the quality of articles from TW is better than that from ML.

Abstract
A high-field superconducting magnet can provide both high-magnetic fields and large-field gradients, which can be used as a special environment for research or practical applications in materials processing, life science studies, physical and chemical reactions, etc. To make full use of a superconducting magnet, shared instruments (the operating platform, sample holders, temperature controller, and observation system) must be prepared as prerequisites. This paper introduces the design of a set of sample holders and a temperature controller in detail with an emphasis on validating the performance of the force and temperature sensors in the high-magnetic field.

Abstract
Background Myxofibrosarcoma is common in the extremities of elderly people and is characterized by a high frequency of local recurrence. Case presentation We report a 37 year old female who presented with a 4-month history of facial pain and a 3-month history of painful progressive swelling in the preauricular area. She underwent a total parotidectomy. The tumor was histopathologically and immunohistochemically diagnosed as a low-grade myxofibrosarcoma. The patient was free of disease 9 months after surgery with uneventful post-operative clinical course. Conclusions Parotid area swelling should always alert doctors. To our knowledge, this is the first case of parotid myxofibrosarcoma. It should be added to the differential diagnosis of diseases of the parotid. We have to recognize this disease and seek adequate treatment for it.

Abstract
Red bayberry (Myrica rubra Sieb. et Zucc) is a special fruit produced in southeastern China. Heavy losses due to postharvest rot and short shelf-life have negatively affected farmers' incomes. In June 2007, a survey was conducted to determine the causal agents of red bayberry (cv. Dongkui) rot in Linhai City, Zhejiang Province. Only a few soft rot fruits with typical gray mold of Botrytis cinerea were found on trees, but 74% (266 of 360) of the fruits that appeared disease free during harvest showed a mass of gray mold after 5 days in storage at 22°C. Brown conidiophores bore botryose heads of hyaline, ellipsoid, unicellular conidia, measuring 9.1 to 16.1 × 8.6 to 11.0 μm. Mycelia were initially whitish and turned gray with age. Black, irregular sclerotia were formed in potato dextrose agar medium. Such features suggested B. cinerea infection (1). Pathogenicity was confirmed by inoculation of 20 healthy red bayberries with a conidial suspension (106/ml); 100% were infected and masses of gray mold were formed 4 days after inoculation. No mock-inoculated fruits were infected. To confirm involvement of B. cinerea, the internal transcribed spacer (ITS) region was amplified with primers ITS4/ITS6 (2). The sequence (Accession No. AM884742) matched 100% to B. cinerea sequences deposited in Genbank (Accession Nos. EF207415, EF207414, and EF207413). To our knowledge, this is the first report of red bayberry rot caused by B. cinerea in China. References: (1) J. Y. Lu. Phytopathogenic Fungi. Chinese Agricultural Publishing, Beijing, 1995. (2) D.

Abstract
OBJECTIVE To observe the clinical effect of a combined therapy in the treatment of simple premature ejaculation. METHODS A total number of 110 patients with simple premature ejaculation were divided into a control group (n = 50), given oral hydrochloric acid sertraline only, and a combined therapy group (n = 60), treated by oral administration of hydrochloric acid sertraline, local inunction of a traditional Chinese medicine and guidance in sexual psychology and knowledge. At the end of a 4-week treatment and 4 weeks after the drug withdrawal, the therapeutic effects were evaluated by ejaculation latency and satisfaction with sexual life. RESULTS The total effectiveness rates at the end of the 4-week treatment were 91.6% and 76% in the combined therapy and the control groups, while those 4 weeks after the drug withdrawal were 68.3% and 42% respectively, both with significant differences in between (P < 0.05 and P < 0.01). CONCLUSION The combined therapy has a satisfactory clinical effect and stability in the treatment of simple premature ejaculation.

Abstract
The chalcid, Oomyzus sokolowskii Kurdjumov has been recorded in many parts of the world as a major larval-pupal, gregarious endoparasitoid of the diamondback moth, Plutella xylostella (Linnaeus), a serious pest of brassica vegetable crops worldwide. This study investigated intraspecific variation between two populations of O. sokiolowskii, one from Cape Verde Islands, West Africa and the other from Hangzhou, China. In all crosses and backcrosses between the two geographical populations, the numbers of progeny and sex ratio of progeny were similar to those obtained within each of the populations, demonstrating complete reproductive compatibility between the two populations. The two populations showed similar responses to temperature with respect to development time and survival of immature stages. Observations on the interactions between the two O. sokolowskii populations and Cotesia plutellae (Kurdjumov), another major parasitoid of P. xylostella, showed that neither population could achieve successful parasitism of P. xylostella larvae already parasitized by C. plutellae. However, both O. sokolowskii populations could achieve hyperparasitism by ovipositing into a mid-late stage larva of C. plutellae developing inside the primary host. Contrary to earlier reports, no evidence of intraspecific variations in ability to hyperparasitize between these two populations of O. sokolowskii was found.

Abstract
OBJECTIVE To establish a cytologic expressing system of rat glutathione S-transferase pi (GST-pi) cDNA for detecting the resistance of HeLa cells to anticancer drugs. METHODS The assessment was made with various anticancer drugs (adriamycin, mitomycin, cisplatinum and vincristine) that showed different cytotoxicities in transfectant HeLa cells with pSV-GT containing rat GST-pi cDNA (HeLa/pSV-GT) or control pSV-neo (HeLa/pSV-neo). Expression levels of GST-pi mRNA in HeLa/pSV-GT and HeLa/pSV-neo were measured by in situ hybridization using Digoxin-labelled cDNA probe. RESULTS HeLa/pSV-GT expressed significantly high degree of GST-pi mRNA, whereas both HeLa/pSV-neo and HeLa cells had very low expression. Cytotoxicities of HeLa/pSV-GT and HeLa/pSV-neo with 4 anticancer drugs were measured by MTT assay. Drug concentrations for yielding 50% inhibition (IC50) in HeLa/pSV-GT by adriamycin, mitomycin and cisplatinum were 70.13 microg/mL, 10.95 microg/mL and 16.52 microg/mL, respectively. In contrast, IC50 in HeLa/pSV-neo was 10.34 microg/mL, 7.48 microg/mL and 13.70 microg/mL, respectively. The cytotoxicities of vincristine on both HeLa/pSV-GT and HeLa/pSV-neo were not significantly different. CONCLUSIONS Our findings suggest that HeLa/pSV-GT containing rat GST-pi cDNA is resistant to some anticancer drugs due to overexpression of GST-pi. Also, HeLa/pSV-GT cell line could serve as a useful cytogenetic model for further research.

Abstract
The retention behaviour of metal chelates of alpha,beta,gamma,delta-tetraphenylporphine (TPP) was studied in reversed-phase high performance liquid chromatography (RP-HPLC). On C18 column, with various organic solvents as mobile phases, the retention of the chelates tends to increase in the following order: ZnTPP < TPP < NiTPP < CuTPP. This retention behaviour can get a good explanation from Horvath's "solvophobic theory". With the assumption that the electrostatic field strength of metal chelates can be measured by the ratio of electronegativity vs. ionic radius (EN/ri) of central metal ion, EN/ri was established to be an index for the retention behaviour of metal-TPP chelates. It was found that lnk' is in good linear relationship with the EN/ri value.

Abstract
OBJECTIVE To study the effect of patching on the speed of reepithelialization, slit-lamp signs of epithelial wound healing, and patient discomfort following a corneal abrasion. METHODS Forty-eight eyes of 46 patients with corneal erosion sparing Bowman membrane were randomized into 2 groups: with or without patching. Slit-lamp examination and photographs of the fluorescein-stained cornea were performed on a daily basis until reepithelialization was complete. Photographs were analyzed using computer-assisted planimetry. RESULTS No statistically significant difference was found between patched (n = 25) and nonpatched (n = 22) eyes for the mean size of the initial erosion (patched eyes, 23.7 mm2; nonpatched eyes, 18.9 mm2; P = .42), linear speed of reepithelialization (reduction over time of the radius of the largest circle included in the erosion: patched eyes, 0.0375 mm/h; nonpatched eyes, 0.0353 mm/h; P = .78), and surface speed of reepithelialization (reduction over time of the erosion area: patched eyes, 0.6510 mm2/h; nonpatched eyes, 0.5657 mm2/h; P = .60). The power to detect a 12-hour delay of epithelial closure was 95%. There were no significant differences between the 2 groups for pain, analgesia, insomnia, aspect of the epithelial border, intensity and duration of stromal edema, Descemet folds, anterior uveitis, and filaments. CONCLUSIONS Patching a corneal erosion does not significantly accelerate reepithelialization and does not alter the epithelial wound healing pattern. It does not reduce the incidence and severity of inflammation nor relieve pain when compared with treatment without patching.

Abstract
OBJECTIVE To evaluate the therapeutic effects of anterior stromal punctures (ASP) in patients with bullous keratopathy (BK). PATIENTS AND METHODS Twenty-seven patients awaiting penetrating keratoplasty with a diagnosis of BK were examined. They were seen before treatment with ASP and 1, 4, and 12 weeks after treatment. The examination included slit-lamp examination, photography of the cornea, ultrasonic pachymetry, central esthesiometry, and pneumotonometry. Subjective evaluations of pain, discomfort, and photophobia were also done using a visual scale model. Photographs were analyzed by computer-assisted planimetry and used to measure the corneal surface covered by bullae and microcysts. Pretreatment and posttreatment values (mean +/- SEM) were compared using the Student paired t test. RESULTS At 3 months, a significant reduction in pain was noted. A decrease in the mean corneal surface covered by bullae (BKPreASP = 2733 +/- 553 microns2; BK3mo = 1006 +/- 356 microns2, P = .004) was observed. A decrease in the esthesiometry (E) measurement (EPreASP = 3.5 +/- 0.4 cm; E3mo = 1.3 +/- 0.3 cm, P < .001), an increase in corneal thickness ([CT] CTPreASP = 869 +/- 24 microns; CT3mo = 902 +/- 21 microns, P < .001), and a decrease in the number of quadrants through which iris (I) details could be seen (IPreASP = 1.7 +/- 0.3; I3mo = 1.2 +/- 0.3, P = .015) were also noted. These findings corroborate the clinical observation of increased subepithelial fibrosis following ASP. CONCLUSIONS Anterior stromal punctures reduce bullae formation and alleviate pain in patients with BK, and they constitute a valuable alternative to penetrating keratoplasty should surgery be delayed or contraindicated.

Abstract
From September 1988 to Dec. 1991, 160 patients, in moderate and advanced stages of hepatic carcinoma were treated with hepatic arterial infusion chemotherapy and embolization. Among them, 64.3% was of massive type, 26.5% of nodular type and 9.1% of diffuse infiltrating type. In most of the cases, the tumor was rich in blood vasculature. Tumor thrombus in the portal vessels and artero--venous fistula were common. The size of tumors were 3cm to 24cm. Most of the tumors decreased in size after treatment. In 132 pts followed-up for six to fifty-one months the one-year survival rate was 10.8% in the Hepatic Artery Infusion group, and 41.9% in the Hepatic Artery Infusion+Hepatic Artery Embolization Iodized Oil Gelfoam group. The longest survival period was 51 months after initial Hepatic Artery Iodized Oil and Hepatic Artery Embolization. Factors influencing therapeutic effects were; (1) stage of the tumor. (2) tumor thrombus in the portal vein. (3) methods of Hepatic Artery Infusion and Hepatic Artery Embolization. (4) selection of embolic material. (5) development of collateral circulation.

Abstract
Twenty patients with liver malignant tumors who were treated by hepatic artery occlusion previously, were treated with additional hepatic infusion or embolization though extrahepatic collaterals. Twenty eight courses of hepatic infusion were performed in 14 patients through the right phrenic artery, collaterals of the proper hepatic artery, collaterals of the superior mesenteric and the pancreaticoduodenal arcades, collaterals of the celiac artery, gastroduodenal artery and left gastric artery. Nine hepatic embolization procedures were performed in 5 patients through the right phrenic artery, collaterals of the proper hepatic artery, gastroduodenal artery and collaterals of right renal artery. No complication related to the treatment procedures occurred in this group. The 1-year and 2-year survival rates were 60% and 10%, respectively.

Abstract
Surface markers were studied at first relapse in 66 cases of acute myeloid leukaemia (AML), using a panel of five monoclonal antibodies directed to CD13, CD14, CD15, CD33 and CD34 antigens. At time of relapse, there was increased expression of CD33 (P = 0.002) and CD34 (P = 0.0001), and decreased expression of CD13 (P = 0.004) and CD15 (P = 0.0001) antigens by comparison to initial diagnosis. There was no strict correlation with the FAB classification. However, CD13 and CD33 expression changes preferentially affected granulocytic leukaemias. At relapse, CD14 and CD34 were significantly more expressed in monocytic than in granulocytic AML (P = 0.01 and 0.003 respectively). In a multivariate analysis, CD34 expression was associated with a low CR rate (P = 0.001) and short survival (P = 0.05), whereas CD15 expression was associated with long survival (P = 0.0004). These results suggest that AML tends to relapse with a less differentiated phenotype than observed at diagnosis and that AML with less differentiated phenotype is of poor prognosis after first relapse, as also observed at diagnosis.

Abstract
1B2 is an IgM monoclonal antibody binding to glycoconjugates bearing the terminal N-acetyllactosamine structure. It agglutinates human erythrocytes. Various cell lines, peripheral blood leucocytes, normal marrow and blast cells from 179 acute myeloid leukaemia (AML) and 11 acute lymphoblastic leukaemia (ALL) patients were tested for reactivity with 1B2. Myelomonocytic (CFU-GM), erythroid (BFU-E), mixed (CFU-GEMM) and leukaemic (CFU-L) progenitor cells were tested in clonogenic assays. Granulocytes, monocytes, myeloid cell lines and 152 out of 179 AML were positive. All FAB subtypes were equally recognised. Lymphocytes, T-cell and Burkitt's cell lines, and 10 of 11 ALL samples were negative. 1B2 inhibited partially day 7 CFU-GM, whereas it was not toxic for BFU-E, CFU-GEMM and day 14 CFU-GM. Leukaemic clonogenic cells were killed in 33 out of 36 AML (more than 40% growth inhibition). 1B2 identifies the more mature steps of myeloid differentiation. It may be useful in the diagnosis of AML, and is a candidate for remission marrow purging before autologous transplantation.

Abstract
The effects of four recombinant hemopoietic growth factors (HGF) and of the impure factor HTB9 on proliferation and maturation of marrow myeloid (CFU-GM) and erythroid (BFU-E) progenitor cells were studied in 22 cases of myelodysplastic syndromes (MDS). In most cases, IL-3, GM-CSF and G-CSF increased significantly the number of myeloid colonies, the best combination being IL-3 + GM-CSF. A significant increase in the myeloid colony/cluster ratio was also noted, but cytological examination of colony cells showed little maturation. The analysis of myeloid colony surface markers with four monoclonal antibodies (to CD13, CD15, CD33 and CD34) showed minor modifications with an increase of CD13 and CD15 in about one third of cases when compared to control without HGF. Erythroid colonies were obtained in one case with erythropoietin alone, and in 19 cases with the addition of GM-CSF and/or IL-3. In short-term liquid cultures, IL-3, GM-CSF and G-CSF increased 3H-thymidine incorporation. We conclude that progenitor cells of most MDS are able to proliferate in the presence of HGF, with wide case-to-case variations. However, the pattern of growth remains abnormal when compared to normal marrow. Although the combination of IL-3 and GM-CSF is the most efficient, there is a large overlap in the stimulating effects of all factors studied.

Abstract
In order to eliminate residual leukemic cells from the marrow of patients with acute myeloid leukemia (AML) prior to autologous bone marrow transplantation, the optimal conditions of utilization of three CD15 murine monoclonal antibodies (MoAb) were investigated. The VIM-D5 MoAb was used with rabbit complement (C'), whereas the 8.27 and SMY15A MoAbs were used in the presence of human C'. These antibodies were also tested after fixation on magnetic beads. In a culture assay in semi-solid medium with a mixture of normal marrow and 1% HL60 cells, a lysis of clonogenic cells greater than 99% was achieved with the three antibodies and two rounds of complement, or with antibody-coated magnetic beads. Cultures of leukemic clonogenic cells (CFU-L) were performed in 47 cases. An inhibition equal to or greater than 90% was achieved in seven cases with VIM-D5, 16 cases with 8.27 and 11 cases with SMY15A and C'. The correlation with cytotoxicity of fresh cells was low. Twenty cases were purged with antibody-coated beads. An inhibition equal to or greater than 90% was observed in 10 cases with VIM-D5, 11 cases with 8.27 and 12 cases with SMY15A. The mean recovery of normal CFU-GM was higher than 70% and that of BFU-E higher than 95% with any method of treatment. It is concluded that efficient marrow purging of clonogenic AML cells can be achieved in some cases without toxicity for normal progenitors. The addition of other MoAbs seems necessary to obtain a significant purge in a majority of cases.

Abstract
The expression of myeloid surface markers was investigated in 41 cases of untreated adult acute lymphoblastic leukemia (ALL). Nineteen cases (46%) reacted with at least one myeloid monoclonal antibody (CD15 in 16 cases, CD13 in 10 cases, CD14 in five cases, and CD33 in four cases). Double-staining confirmed the coexpression of myeloid and lymphoid markers. In addition, 35 samples were tested for CD34 expression. Fourteen of the 17 myeloid-positive cases tested were positive for CD34 vs. eight of 18 negative cases (p less than 0.05). A t(9;22) translocation was found in eight cases, and a t(4;11) translocation in two cases, all expressing CD34 and myeloid antigens. These findings confirm the high frequency of myeloid markers on the surface of adult ALL blasts, and suggest that these leukemias may originate in a poorly differentiated precursor cell with mixed differentiation capacities.

Abstract
A study of surface markers and in vitro growth in semi-solid and liquid medium was performed in 35 patients with newly diagnosed myelodysplastic syndrome (MDS). Surface markers were studied by CD34, CD13, CD14, CD15, and CD33 monoclonal antibodies. There was no strict correlation with the FAB typing, but CD34 was expressed only in refractory anemia with excess of blasts (RAEB) or RAEB in transformation (RAEB-t). CD14 was markedly positive in the 4 cases of chronic myelomonocytic leukemia. Colony-forming cells were assessed by culture in semi-solid medium in the presence of HTB9 as growth factor. Four growth patterns were identified: a) normal growth (6 cases); b) no growth or low plating efficiency (10 cases); c) low colony and high cluster number (15 cases); and d) normal or high colony number with high number of clusters (4 cases). Expression of CD34 was associated with low colony and high cluster number. Finally we studied the proliferation and differentiation capacities in liquid culture without stimulating factor. Fifteen patients had a spontaneous proliferation. This was not correlated with any surface marker. Differentiation assessed by the loss of CD34 and/or the increase of CD15 by more than 20% at day 7 was observed in 21 cases. None of the surface markers or growth patterns was associated with a specific chromosomal abnormality, except the lack of growth in liquid culture observed in all 5q deletion cases. In univariate analysis, RAEB and RAEB-t FAB subtypes, percentage of blasts higher than 5%, staining by CD33 and CD34, and lack of differentiation in liquid culture were significantly associated with progression to leukemia and shorter survival. In multivariate analysis, only CD34 expression (P = .002) and percentage of blasts (P = .05) remained independent significant variables. CD34 was the only significant variable for prediction of survival (P = .05). It is concluded that surface marker analysis at diagnosis and after liquid culture may be a useful tool for the initial evaluation of MDS.

Abstract
X-ray features of 23 cases (25 foci) of non-squamous cell carcinoma and other malignant neoplasms in the trachea and main bronchi were reviewed. They were 15 (17 foci) adenoid cystic carcinomas, 3 carcinoids, 2 mucoepidermoid carcinomas, 1 well-differentiated adenocarcinoma, leiomyosarcoma and extramedullary plasmocytoma each. The symptoms were non-specific leading to a delayed diagnosis more than one year in 52% of cases. The X-ray findings were classified into 3 types: intraluminal polypoid (11 tumors), sessile mass without and with extraluminal invasion (3 and 11 tumors). These tumors were prone to extraluminal invasion and can be demonstrated by X-ray. The air lumen involved appeared as localized expansion in 3 adenoid cystic carcinomas, 1 of which was proved by operation. Routine chest films were of limited value with 30% false negative chest film, 26% mediastinum mass and 30% obstructive pneumonitis/atelectasis. Lesions of posterior tracheal wall and carina were better revealed by lateral tomography. Of the 10 cases with lateral tomography, images were superior to those of AP tomography in 5. Three cases had CT scan, by which intra-tracheal/bronchial lesions, invasions of mediastinum and regional lymph nodes were shown. CT scan is more accurate compared with the other imaging modalities in visualizing these lesions and more helpful in selecting treatment.
