Abstract
Objective: To investigate the short-term outcome of transoral robotic thyroidectomy. Methods: This is a retrospective case series study. The clinicopathologic characteristics and postoperative results of 107 patients who underwent transoral robotic thyroidectomies in the Department of Thyroid and Breast Surgery of the 960th Hospital of People's Liberation Army from May 2020 to August 2023 were retrospectively analyzed. There were 12 males and 95 females, with an age of (31.8±9.4) years (range: 11 to 55 years), including 20 benign tumors and 87 thyroid papillary carcinoma. Postoperative follow-up was carried out through returning visit and telephone, mainly to observe the recovery of postoperative complications, cosmetic effects and recurrence results. Results: All transoral robotic thyroidectomy was successfully completed without conversion to open surgery. The tumor size of thyroid papillary carcinoma patients was (5.6±2.7) mm (range: 2 to 15 mm). Furthermore, central cervical lymph node metastasis was found in 45 cases. The number of central cervical lymph nodes retrieved and metastasized (M(IQR)) were 11 (8) (range: 3 to 26) and 1 (3) (range: 0 to 13), respectively. There was no recurrent laryngeal nerve injury and permanent hypoparathyroidism. The transient hypoparathyroidism after surgery was 8 cases. Other complications occurred as follows: postoperative infection (n=1), left submandibular perforation (n=1), skin scald (n=1), and perioral numbness (n=1), oral tear (n=2). The postoperative stay was 6 (2) days (range: 3 to 11 days). No local lymph node recurrence or metastasis occurred after a follow-up of (22.6±10.0) months (range: 1.0 to 37.4 months). All patients were satisfied with the postoperative cosmetic results, the aesthetic effect score was 9.3 (0.2) (range: 8.4 to 9.6) one month after surgery. Conclusion: For highly screened patients with early thyroid cancer, experienced surgeons can perform a transoral robotic thyroidectomy that has excellent cosmetic results.

Abstract
Objective: To summarize the clinical, radiological characteristics, and prognosis of infectious sacroiliitis in children. Methods: A case-control study was conducted, including 12 cases of infectious sacroiliitis diagnosed in the Rheumatology and Immunology Department of the Children's Hospital affiliated with the Capital Institute of Pediatrics from June 2018 to June 2023. These cases comprised the case group. Concurrently, 28 cases of pediatric idiopathic arthritis involving the sacroiliac joint in the same department served as the control group. Basic patient information, clinical features, laboratory parameters, and clinical treatment outcomes for both groups were collected and analyzed. Independent sample t-tests and chi-squared tests were used for inter-group comparisons. Results: Among the 12 cases in the case group, there were 5 males and 7 females, with a disease duration of 0.8 (0.5, 1.2) months. Nine patients presented with fever, and 1 patient had limping gait. Human leukocyte antigen (HLA)-B27 positivity was observed in 1 case, and there was no family history of ankylosing spondylitis. In the control group of 28 cases, there were 19 males and 9 females, with a disease duration of 7.0 (3.0, 17.0) months. One patient (4%) had fever, and 14 cases (50%) exhibited limping gait. HLA-B27 positivity was found in 18 cases (64%), and 18 cases (64%) had a family history of ankylosing spondylitis. The case group had higher white blood cell count (WBC), neutrophil ratio, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, as well as a higher proportion of unilateral involvement on magnetic resonance imaging and bone destruction on CT compared to the control group ((11.1±6.2)×109 vs. (7.3±2.3)×109/L, 0.64±0.10 vs. 0.55±0.12, 72 (34, 86) vs. 18 (5, 41) mm/1 h, 24.6 (10.1, 67.3) mg/L vs. 3.6 (0.8, 15.0) mg/L, 11/12 vs. 36% (10/28), 9/12 vs. 11% (3/28), t=2.90, 3.07, Z=-2.94, -3.28, χ2=10.55, 16.53, all P<0.05). Conclusions: Pediatric infectious sacroiliitis often presents as unilateral involvement with a short disease history. Elevated WBC, CRP, and ESR, as well as a high rate of bone destruction, are also common characteristics.

Abstract
Silencing genes using small interfering (si) RNA is a promising strategy for treating cancer. However, the curative effect of siRNA is severely constrained by low serum stability and cell membrane permeability. Therefore, improving the delivery efficiency of siRNA for cancer treatment is a research hotspot. Recently, mesoporous silica nanoparticles (MSNs) have emerged as bright delivery vehicles for nucleic acid drugs. A comprehensive understanding of the design of MSN-based vectors is crucial for the application of siRNA in cancer therapy. We discuss several surface-functionalized MSNs' advancements as effective siRNA delivery vehicles in this paper. The advantages of using MSNs for siRNA loading regarding considerations of different shapes, various options for surface functionalization, and customizable pore sizes are highlighted. We discuss the recent investigations into strategies that efficiently improve cellular uptake, facilitate endosomal escape, and promote cargo dissociation from the MSNs for enhanced intracellular siRNA delivery. Also, particular attention was paid to the exciting progress made by combining RNAi with other therapies to improve cancer therapeutic outcomes.

Abstract
The increasing exposure to extreme heatwaves in urban areas from both climate change and the urban heat island (UHI) effect poses multiple threats and challenges to human society. Despite a growing number of studies focusing on extreme exposure, research advances are still limited in some aspects such as oversimplification of human exposure to heatwaves and neglect of perceived temperature as well as actual body comfort, resulting in unreliable and unrealistic estimates of future results. In addition, little research has performed comprehensive and fine-resolution global analyses in future scenarios. In this study, we present the first global fine-resolution projection of future changing urban population exposure to heatwaves by 2100 under four shared socioeconomic pathways (SSPs) considering urban expansion at global, regional, and national scales. Overall, global urban population exposure to heatwaves is rising under the four SSPs. Temperate and tropical zones predictably have the greatest exposure among all climate zones. Coastal cities are projected to have the greatest exposure, followed closely by cities at low altitudes. Middle-income countries have the lowest exposure and the lowest inequality of exposure among countries. Individual climate effects contributed the most (approximately 46.4%) to future changes in exposure, followed by the interactive effect between climate and urbanization (approximately 18.5%). Our results indicate that more attention needs to be paid to policy improvements and sustainable development planning of global coastal cities and some low-altitude cities, especially in low- and high-income countries. Meanwhile, this study also highlights the impact of continued future urban expansion on population exposure to heatwaves.

Abstract
Objective: To compare the surgical outcome of robotic thyroidectomy through transoral approach and the bilateral breast-axillary approach. Methods: Retrospective analysis was made on the clinical data of patients who performed transoral robotic thyroidectomy (TORT group) or bilateral breast-axillary approach (BABA group) in the Department of Thyroid and Breast Surgery, the 960th Hospital of People's Liberation Army from July 2020 to May 2022. Both groups received lobectomy with lymph node dissection of the central region. A total of 100 cases were included in the study, including 48 cases in the TORT group and 52 cases in the BABA group. The propensity score matching method was used for 1∶1 matching of patients between the 2 groups, with a match tolerance of 0.03. There were 31 patients in each group successfully matched. In the TORT group, there were 5 males and 26 females, aged (33.2±7.9) years (range: 21 to 53 years). While there were 4 males and 27 females in the BABA group, aged (34.6±9.2) years (range: 19 to 58 years). The t test, Mann-Whitney U test, χ2 test or Fisher exact test were used to compare the clinical efficacy between the two groups. Results: All the patients successfully completed robotic thyroid surgery without conversion to open surgery. Compared with BABA group, the TORT group had longer operation time ((211.3±57.2) minutes vs. (126.2±37.8) minutes, t=6.915, P<0.01), shorter drainage tube retention time ((5.4±1.0) days vs. (6.4±1.2) days, t=-3.544, P=0.001), shorter total hospital stay ((6.6±1.2) days vs. (7.4±1.3) days, t=-2.353, P=0.022), and higher cosmetic score (9.46±0.25 vs. 9.27±0.26, t=2.925, P=0.005). There was no significant difference between the two groups in the number of lymph nodes dissection, metastasis in the central compartment, and the incidence of postoperative complications (all P>0.05). Conclusions: Compared with the bilateral breast-axillary approach, the transoral vestibular approach of robotic thyroidectomy is also safe and effective. It shows similar surgical results to the bilateral breast-axillary approach in strictly selected patients, but the postoperative recovery speed is much faster, and the hospital stay is shorter. Transoral robotic thyroidectomy is a more recommended surgical method for patients with high aesthetic demand.

Abstract
Rill erosion is one of the major environmental problems in the world; it is an important factor with regard to land degradation and has a serious impact on production and daily life in the region. The widely distributed Yuanmou group stratum promotes the development of rill erosion, whereby the strong time-concentrated rainfall and the alternating arid-humid climate prepare the ground for the development of rills in soils. Therefore, a study of the processes of slope rill erosion was carried out, and a gravel-soil slope in the Yuanmou dry-hot valley was chosen to simulate short-term heavy rainfall (25 mm/h) (No. 1 plot) and moderate rainfall (15 mm/h) (No. 2 plot), to study the erosion processes of soil and the dynamic characteristics of runoff involved in erosion. The study results showed that the width of runoff was significantly different between the two plots, while the depth of runoff was not significantly different. During the rill formation process, the width of the two plots first decreased and then increased with increasing washout duration, while its depth did not change significantly. Flow was the key factor in determining the hydraulic characteristics of runoff, and it had a significant or extremely significant positive correlation with hydraulic characteristics parameters, except in the case of Fr (Froude number) (r = 0.039). The total sediment content (CS) of plot No. 1 (0.158 g/cm3) was significantly different from that of plot No. 2 (0.153 g/cm3), and both CSs in the two plots decreased with increasing washout duration. The CS had an extremely significant negative correlation with τ (runoff shear force) (r = -0.863 **) and DW-f (Darcy-Weisbach drag coefficient) (r = -0.863 **) and a significant negative correlation with Re (Reynolds number) (r = -0.735 *) in the short-term heavy rainfall experiment, while the CS had a significant positive correlation with V (velocity) (r = 0.814 *), R (hydraulic radius) (r = 0.811 *) and P (unit stream power) (r = 0.811 *) in the moderate rainfall experiment. The results of this study will help guide further examination of the processes involved in the dynamic mechanisms of rill erosion on slopes under short-term heavy rainfall conditions.

Abstract
This paper explores the impacts of the evolution of the dietary structure of the population on national food security using the food self-sufficiency rate under various statistical dimensions and simulate various food security scenarios for China in the medium- and long-term future. This study indicates that China’s rapid economic and social development and the continuous improvement in people’s living standards appears to be declining in the food self-sufficiency rate. The analysis regarding the factors influencing the food self-sufficiency rate revealed that the improved dietary structure, involving an increase in animal-based food product consumption, has led to a decrease in China’s food self-sufficiency rate. It concludes that the dietary structure is likely to continue to move toward increased consumption of animal-based food products in China for the future. The research results will assist decision-makers in formulating scientific food self-sufficiency rate targets and food security strategies

Abstract
Hydroxy-safflower yellow A (HSYA) is the chief component of safflower against myocardial ischemia (MI), and belongs to biopharmaceutics classification system (BCS) III drugs. Its structure contains multiple hydroxyl groups, contributing to its high polarity and poor oral bioavailability. The main objective of this study was to probe the potential of oral penetration enhancer n-[8-(2-hydroxybenzoyl) amino] sodium octanoate (SNAC) and cationic copolymer Eudragit®EPO (EPO) to promote absorption of HSYA. HSYA composites (SNAC-HSYA-EPO) were formed by hydrogen bonding and van der Waals force. SNAC-HSYA-EPO has biocompatibility, and can improve the membrane fluidity, uptake, transport, and penetration of Caco-2 cells. The mechanism of promoting of SNAC-HSYA-EPO may be related to energy and P-glycoprotein (P-gp) when compared with the inhibitor NaN3 and verapamil group. In the pharmacokinetic (PK) results, SNAC-HSYA-EPO significantly improved oral bioavailability. Pharmacodynamics (PD) results determined that SNAC-HSYA-EPO could improve the symptoms of MI. The mechanism of the SNAC-HSYA-EPO anti-MI is related to alleviating inflammation and anti-apoptosis to protect the heart. In summary, SNAC-HSYA-EPO prepared in this study possessed a complete appearance, high recombination rate and excellent oral permeability promoting ability. SNAC-HSYA-EPO has the potential to improve oral bioavailability and further enhance the anti-MI effect of HSYA.

Abstract
Objective: To investigate the clinical characteristics of systemic juvenile idiopathic arthritis combined with coronary artery dilatation. Methods: A retrospective analysis was performed on the clinical data, including clinical manifestations, blood routine, inflammatory factors, echocardiography, vascular ultrasound and CT angiography, treatment and outcomes, etc, of 5 cases with systemic juvenile idiopathic arthritis combined with coronary artery dilation admitted to Department of Rheumatology in the affiliated Children's Hospital of Capital Institute of Pediatrics from May 2019 to June 2021. Results: There were 2 males and 3 females among 5 cases. The onset age ranged from 7 months to 4 years 7 months.The diagnostic time ranged from 1.5 months to 3.0 months.Four cases were diagnosed as atypical Kawasaki disease. Three cases showed unilateral coronary artery dilation.Two cases showed bilateral coronary artery dilation.Four cases developed multiple organ injuries.Three cases developed macrophage activation syndrome.Three cases developed lung injury.Two cases developed pericardial effusion.One case developed pulmonary hypertension.As for treatment, 3 cases treated with methylprednisolone pulse therapy and methotrexate combined with cyclosporine, improved after the final application of biological agents, and have stopped prednisone. The other 2 cases were treated with adequate oral prednisone and gradually reduced, and methotrexate was added at the same time, 1 case relapsed in the process of reduction. No other vascular involvement was found in 5 cases. Coronary artery dilation recovered completely after 1 to 3 months of treatment. Conclusions: Systemic juvenile idiopathic arthritis combined with coronary artery dilatation has the clinical characteristics of small onset age, long diagnostic time, prone to multiple organ injuries. Corticosteroids and conventional immunosuppressive agents are not sensitive, and biological agents should be used as soon as possible.The prognosis of coronary artery dilation is good after timely treatment.

Abstract
Objective: To analyze the changes in glucose after using a decision support system (DSS) of a smartphone mobile application (APP) in adults with type 1 diabetes mellitus (T1DM). Methods: In the intervention study, the data (including general information at the time of registration) of adult T1DM patients enrolled in the Chinese T1DM Registration Management Project and registered with TangTangQuan® APP were collected. Within 1 year after registration, fasting blood glucose, pre-prandial and postprandial blood glucose at the three meals, blood glucose before bedtime and in nocturnal time were collected every 3 months. Frequencies of total recorded glucose values and proportion of different ranges of glycemia were also collected and analyzed, including the range between 3.9-7.8 mmol/L (Euglycemia), ranged below 3.9 mmol/L (Hypoglycemia) and range above 13.9 mmol/L (hyperglycemia). The patients were divided into 3 groups according to the daily use frequency of DSS (Low/Moderate/High frequency groups). The changes in point blood glucose, the proportion of hyperglycemia and hypoglycemia over time were compared among different groups, as well as the baseline characteristics and glucose characteristics of patients. Results: A total of 629 eligible T1DM patients were included, including 216 (34.3%) males and 413 (65.7%) females, aged (31.5±10.8) years, and disease duration [M(Q1, Q3)] of 1.2 (0.1, 7.4) years. There were 239, 189 and 201 patients in the low, moderate and high frequency groups, respectively. Significant differences were observed among the three groups in all timepoints of self-monitoring blood glucose except for the glucose before bedtime from 10 to 12 months after registration (all P values<0.05), and the glucose level at each point in the high frequency group was lower than that in the other two groups. In the first three months after registration, there was no difference in the proportion of hypoglycemia among the three groups (P>0.05). However, from 10 to 12 months after registration, the proportion [M(Q1, Q3)] of hypoglycemia [3.34% (0.85%, 7.40%), 3.00% (0.78%, 6.17%), 1.81% (0.37%, 4.69%)] (P=0.022) between groups (from low to high frequency groups) and hyperglycemia [4.04% (0, 12.16%), 1.88% (0, 7.80%), 0.81% (0, 3.87%)] (P=0.001) were significantly different. Conclusions: The DSS function of mobile APP is helpful to the glucose management of adult patients with T1DM within 1 year after registration. The average blood glucose in adults with T1DM decreased, and the proportions of hyperglycemia and hypoglycemia were also reduced.

Abstract
Plant species diversity (PSD) has always been an essential component of biodiversity and plays an important role in ecosystem functions and services. However, it is still a huge challenge to simulate the spatial distribution of PSD due to the difficulties of data acquisition and unsatisfactory performance of predicting algorithms over large areas. A surge in the number of remote sensing imagery, along with the great success of machine learning, opens new opportunities for the mapping of PSD. Therefore, different machine learning algorithms combined with high-accuracy surface modeling (HASM) were firstly proposed to predict the PSD in the Xinghai, northeastern Qinghai-Tibetan Plateau, China. Spectral reflectance and vegetation indices, generated from Landsat 8 images, and environmental variables were taken as the potential explanatory factors of machine learning models including least absolute shrinkage and selection operator (Lasso), ridge regression (Ridge), eXtreme Gradient Boosting (XGBoost), and Random Forest (RF). The prediction generated from these machine learning methods and in situ observation data were integrated by using HASM for the high-accuracy mapping of PSD including three species diversity indices. The results showed that PSD was closely associated with vegetation indices, followed by spectral reflectance and environmental factors. XGBoost combined with HASM (HASM-XGBoost) showed the best performance with the lowest MAE and RMSE. Our results suggested that the fusion of heterogeneous data and the ensemble of heterogeneous models may revolutionize our ability to predict the PSD over large areas, especially in some places limited by sparse field samples.

Abstract
Background Methicillin-resistant Staphylococcus aureus (MRSA) biofilm-associated bacterial infection is the primary cause of nosocomial infection and has long been an ongoing threat to public health. MRSA biofilms are often resistant to multiple antimicrobial strategies, mainly due to the existence of a compact protective barrier; thus, protecting themselves from the innate immune system and antibiotic treatment via limited drug penetration. Results A hierarchically structured hydrogen sulfide (H2S)-releasing nano-disinfectant was presented, which was composed of a zinc sulfide (ZnS) core as a H2S generator and indocyanine green (ICG) as a photosensitizer. This nano-disinfectant (ICG-ZnS NPs) sensitively responded to the biofilm microenvironment and demonstrated efficient eradication of MRSA biofilms via a synergistic effect of Zn2+, gas molecule-mediated therapy, and hyperthermia. Physically boosted by released H2S and a near-infrared spectroscopy-induced hyperthermia effect, ICG-ZnS NPs destroyed the compactness of MRSA biofilms showing remarkable deep-penetration capability. Moreover, on-site generation of H2S gas adequately ameliorated excessive inflammation, suppressed secretion of inflammatory cytokines, and expedited angiogenesis, therefore markedly accelerating the in vivo healing process of cutaneous wounds infected with MRSA biofilms. Conclusion ICG-ZnS NPs combined with NIR laser irradiation exhibited significant anti-biofilm activity in MRSA biofilms, can accelerate the healing process through deep-penetration and anti-inflammatory effectuation. The proposed strategy has great potential as an alternative to antibiotic treatment when combating multidrug-resistant bacterial biofilms. Graphical Abstract ![]()

Abstract
As a prominent part of global and regional terrestrial carbon (C) pools, increases in forest biomass C sinks can be attributed to either forest areal expansion (FAE) or increased biomass C density (IBCD). Accurate estimates of the relative contributions of FAE and IBCD to forest C sequestration can improve our understanding of forest C cycling processes and will help to formulate rational afforestation policies to cope with global warming. In this study, the Continuous Biomass Expansion Factor (CBEF) model and Forest Identity concept were used to map the spatiotemporal variation of the relative contribution of FAE and IBCD to the C sequestration of forest (natural and planted forests) in China and seven regions during the past 40 years. Our results suggest that: (1) total forest biomass C density and stocks of forest increased from 35.41 Mg C ha-1 and 4128.50 Tg C to 43.95 Mg C ha-1 and 7906.23 Tg C in China from 1977 to 2018, respectively; (2) for all forests, the IBCD has been a smaller contributor to C sinks than FAE in China from 1977 to 2018 (33.27 vs. 66.73%); (3) the contribution of FAE to C sinks is greater than that of IBCD in planted forests (63.99 vs. 36.01%), while in natural forests, IBCD has a larger contribution than FAE (57.82 vs. 42.18%) from 1977 to 2018 and the relative contribution of FAE has exceeded IBCD in the last decade; and (4) these patterns varied at the regional level such that the relative contribution of FAE increased for planted forests in most regions but for natural forests, IBCD gradually reached saturation and C stocks declined in northern regions in the last decade. The results from this study suggest that total biomass C sinks will keep increasing because of the increased forest area contributed by afforestation and the relatively young trees in planted forests. This study facilitates a more comprehensive assessment of forest C budgets and improves our understanding of ecological mechanisms of forest biomass carbon stock and dynamics.

Abstract
Objective: To examine the surgical outcome of transoral robotic thyroidectomy. Methods: Clinic data of total 30 cases of transoral robotic thyroidectomy at the Department of Thyroid and Breast Surgery, the 960th Hospital of People's Liberation Army from May 2020 to December 2020 were analyzed retrospectively. There were 3 males and 27 females, aged (31.5±11.0) years (range: 17 to 55 years), including 6 cases of benign tumor and 24 cases of malignant cancer (all papillary thyroid carcinoma). An inverted U-shaped incision 1.5 cm in length was made over the end of the frenulum of the lower lip. A wide subplatysmal space was created by bluntly passing with a vascular tunneller (8 mm diameter), and a 12 mm trocar was inserted through the lip incision for the camera port. Lateral oral mucosal incisions 8 mm in length were made near both lateral labial commissures, 8 mm robot trocars were inserted through the incisions. An 5 mm trocar was inserted through an incision made along the patient's right axillary fold into the subplatysmal working space and was connected with 5 mm ProGrasp for counter traction during the operation and for later drain insertion. Numerical scoring system (NSS) was used to assess cosmetic effect 1 month post-operation. Results: All the 30 transoral robotic thyroidectomies was successful, no case conversed to open operation. Postoperative hospital stay was (6.3±1.2) days (range: 4 to 10 days). The tumor size of thyroid cancers was (5.3±3.0) mm (range: 2 to 15 mm). Lymph node metastasis was observed in 12 cases. The retrieved central lymph node number was 10.5±4.4 (range: 4 to 20), while the central metastatic lymph node number was 2(2) (range: 1 to 11). Postoperative transient hypoparathyroidism occurred in 2 cases. Permanent hypoparathyroidism and vocal cord palsy didn't occur. Other surgical complications included hematoma, surgical site infection and perforation of chin flap, retrospectively in 1 case. Local regional lymph node recurrence wasn't developed during 1 to 7 months follow-up. All patients were satisfied with the postoperative cosmetic outcomes,NSS was 9.4±0.8 (range: 8.7 to 9.6). Conclusion: Transoral robotic thyroidectomy is safe and effective, suitable for early thyroid cancers without lateral lymph node metastasis, and has superior cosmetic results when the patients are selected carefully.

The clinicopathologic characteristics, operation times, perioperative complications, and oncologic outcomes of patients underwent robotic thyroidectomy were collected and reviewed retrospectively. There were 216 males and 784 females, aging (42.3±11.5) years (range: 7 to 75 years). There were 270 cases with benign tumors, and 730 cases with malignant cancers (the tumor diameter was (7.9±6.7) mm (range: 0.1 to 60.0 mm)). Results: There were 999 patients received robotic thyroidectomy using BABA approach successfully, while only 1 case conversed to open operation. The postoperative hospital stay was (7.5±2.5) days (range: 2 to 30 days). Among the 730 patients with thyroid cancers, 725 cases (99.3%) were papillary thyroid carcinoma, 579(79.3%) cases were with papillary thyroid microcarcinoma. Lymph node metastasis was observed in 371(50.8%) cases. The retrieved central lymph node number was 11.2±6.1 (range: 1 to 44),and the retrieved lateral lymph node number was 14.0±8.8 (range: 1 to 52). Postoperative transient hypoparathyroidism and vocal cord palsy occurred in 247(24.70%) and 56(5.60%) cases. Both of permanent hypoparathyroidism and vocal cord palsy occurred in 2 (0.20%) cases. Other surgical complications included chyle leakage (6.1%, 28/460), trachea injury (0.40%, 4/1 000), carotid artery injury (0.10%, 1/1 000). Local regional lymph node recurrence was developed in 4 patients. All patients were satisfied with the postoperative cosmetic outcomes. Conclusions: Robotic thyroidectomy by BABA is safe and effective, suitable for large benign tumors and early thyroid cancers with central or lateral lymph node metastasis. It could obtain superior cosmetic results.

Abstract
Purpose High central blood pressure is more predictive of cardiovascular disease (CVD) versus high peripheral blood pressure. Measures of central pressures (CPs) include, central systolic blood pressure (CSBP) and central diastolic blood pressure. Measures of central pressures augmentation (CPsA) include augmentation pressure (AP) and the augmentation index @ 75 beats·min-1 (AIx@75). Increased sympathetic tone (ST) is also associated with CVD. The low to high frequency ratio (LF/HF) is often used to determine sympatho-vagal balance. Given the association between ST, CPs, CPsA and CVD there is a need to understand the association between these predictors of CVD. The aims of this study were to examine the association between the LF/HF ratio, CPs, and CPsA in men and women collectively and based on gender. Methods We measured the LF/HF ratio, CSBP, AP, and AIx@75 in 102 participants (41F/61M). The LF/HF ratio was determined via power spectral density analysis. CSBP, AP, and AIx@75 were determined via applanation tonometry. Results The LF/HF ratio was inversely associated with AP (r = -0.26) and AIx @75 (r = -0.29) in the combined group of men and women. The LF/HF ratio was inversely associated with CSBP (r = -0.27), AP (r = -0.28), and AIx@75 (r = -0.32) in men, but not in women. Conclusion There is an inverse association between the LF/HF ratio, AP, and AIx@75 in men and women combined. The association between the LF/HF ratio, CSBP, AP, and AIx@75, differs based on gender.

Abstract
Quantifying the impact of urbanization on extreme climate events is significant for ecosystem responses, flood control, and urban planners. This study aimed to examine the urbanization effects on a suite of 36 extreme temperature and precipitation indices for the Beijing-Tianjin-Hebei (BTH) region by classifying the climate observations into three different urbanization levels. A total of 176 meteorological stations were used to identify large cities, small and medium-size cities and rural environments by applying K-means cluster analysis combined with spatial land use, nighttime light remote sensing, socio-economic data and Google Earth. The change trends of the extreme events during 1980-2015 were detected by using Mann-Kendall (MK) statistical test and Sen's slope estimator. Urbanization effects on those extreme events were calculated as well. Results indicated that the cool indices generally showed decreasing trends over the time period 1980-2015, while the warm indices tended to increase. Larger and more significant changes occurred with indices related to the daily minimum temperature. The different change rates of temperature extremes in urban, suburban and rural environments were mainly about the cool and warm night indices. Urbanization in medium-size cities tended to have a negative effect on cool indices, while the urbanization in large cities had a positive effect on warm indices. The significant difference of urbanization effect between large and medium-size cities lay in the daily maximum temperature. Results also demonstrated the scale effect of the urbanization on the extreme temperature events. However, the results showed little evidence of the urban effect on extreme precipitation events in the BTH region. This paper explored the changes in temperature and precipitation extremes and qualified the urbanization effects on those extreme events in the BTH region. The findings of this research can provide new insights into the future urban agglomeration development projects.

Abstract
Andrias davidianus is widely recognized in traditional medicine as a cure-all to treat a plethora of ailments. In a previous study, a novel antibacterial peptide named andricin B was isolated from A. davidianus blood. In this study, we investigated andricin B structure and its mode of action. Circular dichroism spectra suggested that andricin B adopts a random coil state in aqueous solution and a more rigid conformation in the presence of bacteria. Moreover propidium iodide/fluorescein diacetate double staining indicated that bacteria treated with andricin B were not immediately eliminated. Rather, there is a gradual bacterial death, followed by a sublethal stage. Scanning electronic microscope imaging indicates that andricin B might form pores on cell membranes, leading to the release of cytoplasmic contents. These results were consistent with flow cytometry analysis. Furthermore, Fourier transform infrared spectroscopy suggests that andricin B induces changes in the chemical properties in the areas surrounding these "pores" on the cell membranes. SIGNIFICANCE AND IMPACT OF THE STUDY: The results of this study suggested the new perspectives about the mode of action of antimicrobial peptide (AMP) active against sensitive bacteria. The AMP was able to be in a random coiled state in aqueous solution but to change to a more rigid one in the presence of sensitive bacteria. Exposure to AMP might not lead to immediate death of treated bacteria, rather bacteria concentration decreased gradually flattening at a sublethal stage. These findings will help people to understand better how the AMPs activate against sensitive bacteria.

Abstract
Grassland, as an important part of land cover, plays an important role in the global carbon cycle and carbon balance. Net ecosystem productivity (NEP) is a key indicator of the carbon cycle process and an important factor in assessing ecosystem security and maintaining ecosystem balance. In this paper, Boreal Ecosystem Productivity Simulator (BEPS) combining meteorological data, leaf area index, and land cover type data were used to simulate the grassland NEP of China from 1979 to 2008. This model was also used to analyze the responses to changes in climate factors, interannual variation in carbon conversion efficiency, drought stress coefficient, and water use efficiency of grassland in China. Results showed that from 1979 to 2008, the mean annual grassland NEP was 13.6 g C/m2 with weak carbon sinks. The grassland NEP distribution increased from northwest to southeast across China. Regions with NEP of > 0 (C sink) accounted for 73.1% of the total grassland area of China. The total C sequestration reached 26.6 Tg yearly, and grassland NEP was positive from 1979 to 2008. The annual changing characteristics were analyzed. Grassland NEP was positive with carbon sink from June to September, which was negative with carbon source in the remaining months. The carbon conversion efficiency and water use efficiency of the grassland increased significantly within 30 years. NEP showed positive correlation with precipitation (accounting for 74.2% of the total grassland area was positively correlated) but weakly positive correlation with temperature (50.2% of the case). Furthermore, significant positive correlation was found between grassland NEP and precipitation, especially in northeastern and central Inner Mongolia, northern Tianshan of Xinjiang, southwestern Tibet, and southern Qinghai Lake.

Abstract
Objective:To discuss the effect of obesity on the operation of thyroid gland surgery and surgical results.Method:The clinical data of 446 patients who underwent robot thyroid surgery through bilateral axillo-breast approach (BABA) from the General Hospital of Jinan Military region from February 2014 to November 2017 were analyzed retrospectively, and the patients were divided into BMI<25 kg/m²; group, BMI 25-30 kg/m²; group and BMI>30 kg/m²; group according to body mass index (BMI). The operative complications were compared between the three groups of benign and malignant patients, such as operation time, postoperative lead flow, postoperative hospitalization time, tumor size (malignant), lymph node metastasis (malignant), cosmetic satisfaction score, laryngeal nerve injury and parathyroid function decrease. Statistical methods using Variance analysis and χ² test to compare the differences between the two groups of indicators, difference is statistically significant (P<0.05).Result:The difference of operation time, postoperative average hospitalization time and postoperative drainage fluid volume in 3 groups was not statistically significant(P>0.05). ①Intraoperative and postoperative pathological results were benign: BMI<25 kg/m²; group 69 cases, BMI 25-30 kg/m²; group 48 cases, BMI>30 kg/m²; group 8 cases, temporary recurrent laryngeal nerve injury were 1 case, 0 case and 0 case respectively, temporary parathyroid function decrease 3 cases, 2 cases and 1 case. ②Intraoperative and postoperative pathological results were malignant:BMI<25 kg/m²; group 180 cases, BMI 25-30 kg/m²; group 119 cases,BMI>30 kg/m²; group 22 cases, temporary recurrent laryngeal nerve injury were 2 cases,1 case and 0 case respectively, temporary parathyroid dysfunction in 64 cases,29 cases and 5 cases respectively.③1 patient in BMI<25 kg/m²; group had lymphatic leakage after operation, 1 patient in BMI 25-30 kg/m²; group had subcutaneous tunnel hemorrhage, and 1 patient had lymphatic leakage during operation.Conclusion:For overweight or obese patients, the da Vinci robot thyroid operation is reliable, does not increase the risk of surgical complications, but also has a good cosmetic effect.

Abstract
As an important cause of global warming, CO2 concentrations and their changes have aroused worldwide concern. Establishing explicit understanding of the spatial and temporal distributions of CO2 concentrations at regional scale is a crucial technical problem for climate change research. High accuracy surface modeling (HASM) is employed in this paper using the output of the CO2 concentrations from weather research and forecasting-chemistry (WRF-CHEM) as the driving fields, and the greenhouse gases observing satellite (GOSAT) retrieval XCO2 data as the accuracy control conditions to obtain high accuracy XCO2 fields. WRF-CHEM is an atmospheric chemical transport model designed for regional studies of CO2 concentrations. Verified by ground- and space-based observations, WRF-CHEM has a limited ability to simulate the conditions of CO2 concentrations. After conducting HASM, we obtain a higher accuracy distribution of the CO2 in North China than those calculated using the classical Kriging and inverse distance weighted (IDW) interpolation methods, which were often used in past studies. The cross-validation also shows that the averaging mean absolute error (MAE) of the results from HASM is 1.12 ppmv, and the averaging root mean square error (RMSE) is 1.41 ppmv, both of which are lower than those of the Kriging and IDW methods. This study also analyses the space-time distributions and variations of the XCO2 from the HASM results. This analysis shows that in February and March, there was the high value zone in the southern region of study area relating to heating in the winter and the dense population. The XCO2 concentration decreased by the end of the heating period and during the growing period of April and May, and only some relatively high value zones continued to exist.

Abstract
Crystalline/amorphous interfaces (CAIs) confer outstanding mechanical properties on crystalline/amorphous nanostructured multilayers (C/ANMs), which are widely used in micro/nanodevices, because their unique interfacial structure possesses high strain compatibility. In this study, Cu/X (X = Cu-Ti, HfO2) C/ANMs with equal layer thicknesses (h) were comparatively investigated in terms of size-dependent hardness (H) and thermal stability to uncover the fundamental difference(s) between Cu/Cu-Ti and Cu/HfO2. It was found that both as-deposited Cu/Cu-Ti and Cu/HfO2 C/ANMs exhibited a maximum hardness at a critical thickness of h ∼30 nm, which was caused by a transition from confined dislocation gliding to dislocation transmission across the interface. Specifically, the Cu/Cu-Ti C/ANMs exhibited annealing hardening, whereas the Cu/HfO2 C/ANMs exhibited annealing softening associated with a minimum softening at h ∼ 30 nm, which was closely correlated with their thermal stability. In comparison with monolithic amorphous X thin films, the glassy X nanolayers in the present Cu/X C/ANMs exhibited reduced thermal stability and a trend that smaller sizes led to higher stability. The underlying mechanism of the size-dependent crystallization behavior of X nanolayers is discussed in terms of the constraining effects of the interface. These findings provide deep insights into the design of Cu/metallic-glass and Cu/ceramic-glass C/ANMs with optimal performance.

Abstract
Dengue transmission in urban areas is strongly influenced by a range of biological and environmental factors, yet the key drivers still need further exploration. To better understand mechanisms of environment-mosquito-urban dengue transmission, we propose an empirical model parameterized and cross-validated from a unique dataset including viral gene sequences, vector dynamics and human dengue cases in Guangzhou, China, together with a 36-year urban environmental change maps investigated by spatiotemporal satellite image fusion. The dengue epidemics in Guangzhou are highly episodic and were not associated with annual rainfall over time. Our results indicate that urban environmental changes, especially variations in surface area covered by water in urban areas, can substantially alter the virus population and dengue transmission. The recent severe dengue outbreaks in Guangzhou may be due to the surge in an artificial lake construction, which could increase infection force between vector (mainly Aedes albopictus) and host when urban water area significantly increased. Impacts of urban environmental change on dengue dynamics may not have been thoroughly investigated in the past studies and more work needs to be done to better understand the consequences of urbanization processes in our changing world.

Abstract
OBJECTIVE Dopamine receptor (DR) signaling is involved in the pathogenesis of autoimmune diseases. We aimed to measure the expression levels of DR1-5 on B cells from patients with rheumatoid arthritis (RA) and to analyze the relationship between DRs and clinical manifestations, inflammatory biomarkers, functional status and disease activity. METHODS A total of 29 patients with RA, 12 healthy donors and 12 patients with osteoarthritis (OA) were recruited in this study. Flow cytometry was used to measure the levels of DR1-5 expressed on B cells. The relationships between B cell DR expressions and clinical features in RA patients were analyzed using the Spearman correlation test. RESULTS The expression levels of B cell DR1-5 in both the RA and OA groups were lower than those in healthy controls. After 3 months of medication, all five receptors were elevated in RA patients, with DR2 and DR3 being significantly increased from the baseline. DR2 expression on B cells was negatively correlated with inflammatory biomarkers and disease activity. CONCLUSION RA patients had lower expression level of DR2 on B cells compared to the healthy controls, and the level of DR2 negatively correlated with the disease activity. DR2 and DR3 might be novel predictors of patient responses to disease modifying antirheumatic drug therapy.

Abstract
UNLABELLED This study aimed to investigate the reduction of patulin (PAT) in apple juice by 12 inactivated Alicyclobacillus strains. The reduction rate of PAT by each strain was determined by high-performance liquid chromatography (HPLC). The results indicated that the removal of PAT was strain specific. Alicyclobacillus acidoterrestris 92 and A. acidoterrestris 96 were the most effective ones among the 12 tested strains in the removal of PAT. Therefore, these two strains were selected to study the effects of incubation time, initial PAT concentration and bacteria powder amount on PAT removal abilities of Alicyclobacillus. The highest PAT reduction rates of 88·8 and 81·6% were achieved after 24-h incubation with initial PAT concentration of 100 μg l(-1) and bacteria powder amount of 40 g l(-1) , respectively. Moreover, it was found that the treatment by these 12 inactivated Alicyclobacillus strains had no negative effect on the quality parameters of apple juice. Similar assays were performed in supermarket apple juice, where inactivated Alicyclobacillus cells could efficiently reduce PAT content. Taken together, these data suggest the possible application of this strategy as a means to detoxify PAT-contaminated juices. SIGNIFICANCE AND IMPACT OF THE STUDY Inactivated Alicyclobacillus cells can efficiently reduce patulin concentration in apple juice. It provides a theoretical foundation for recycling of Alicyclobacillus cells from spoiled apple juice to reduce the source of pollution and the cost of juice industry. This is the first report on the use of Alicyclobacillus to remove patulin from apple juice.

Abstract
The present research described the preparation, purification, and identification of antioxidant peptides from goat milk casein (GMC). Goat milk casein was hydrolyzed by using a combination of neutral and alkaline proteases to obtain goat milk casein hydrolysates (GMCH) with high antioxidant activity. After desalting by nonpolar macroporous absorption resin, GMCH was isolated and purified by gel filtration chromatography and reversed-phase HPLC, respectively, and further identified by nanoliter electrospray ionization-tandem mass spectrometry. Antioxidant activities of GMC, GMCH, and pure peptides were evaluated and compared using free radical scavenging activity, metal ion chelating ability, and anti-lipid peroxidation ability. Compared with GMC, the free radical-scavenging ability and ferrous ion-chelating ability of GMCH increased significantly. The inhibition effect of lipid peroxidation of GMCH was much stronger than that of tert-butylhydroquinone and phytogermine and a little lower than that of ascorbic acid. The antioxidant activity of GMCH could be attributed to the high antioxidant activity of oligopeptides, especially 5 novel oligopeptides: Val-Tyr-Pro-Phe, Phe-Gly-Gly-Met-Ala-His, Phe-Pro-Tyr-Cys-Ala-Pro, Tyr-Val-Pro-Glu-Pro-Phe, and Tyr-Pro-Pro-Tyr-Glu-Thr-Tyr, which were first observed in GMCH. The antioxidant activity of these 5 novel oligopeptides and GMCH increased 3.59 to 380 times compared with GMC, combining anti-lipid peroxidation ability of GMCH, which indicated that GMCH and its purified fractions in different stages could be used as functional food ingredients, food additives, and pharmaceutical agents in the future.

Abstract
AIMS To purify and primarily characterize an anti-Alicyclobacillus bacteriocin produced by Bifidobacterium animalis subsp. animalis CICC 6165, suggested to be named bificin C6165. METHODS AND RESULTS During purification of the bificin C6165, optimal recovery was achieved with ammonium sulfate precipitation followed by two chromatographic steps. Mass spectrometry analyses revealed a distinctive peak corresponding to a molecular mass of 3395·1 Da. This bacteriocin was heat stable, effective after refrigerated storage and freeze-thaw cycles. The primary mode of action of bificin C6165 is most probably due to pore formation, as indicated by the efflux of K(+) from metabolically active cells of Alicyclobacillus acidoterrestris. In the presence of 10 mmol l(-1) gadolinium, bificin C6165 did not affect cells of Alicyclobacillus acidoterrestris. This suggests that the mode of action of bificin C6165 relies on a net negatively charged cell surface. CONCLUSIONS Bificin C6165 is indeed a novel bacteriocin and it exhibited remarkable potency for Alicyclobacillus control. SIGNIFICANCE AND IMPACT OF THE STUDY Application of bacteriocins in preservation of fruit juices has seldom been studied. Bificin C6165 may be an alternative method to control juice spoilage by this Alicyclobacillus acidoterrestris and meet increasing consumer demand for nature and artificial chemical additive-free food products.

Abstract
AIMS This study aims to assess the removal mechanism of patulin using heat-treated Saccharomyces cerevisiae cells and identify the role of different cell wall components in the binding process. METHODS AND RESULTS In order to understand the binding mechanism, viable cells, heat-treated cells, cell wall and intracellular extract were performed to assess their ability to remove patulin. Additionally, the effects of chemical and enzymatic treatments of yeast on the binding ability were tested. The results showed that there was no significant difference between viable (53·28%) and heat-treated yeast cells (51·71%) in patulin binding. In addition, the cell wall fraction decreased patulin by 35·05%, and the cell extract nearly failed to bind patulin. Treatments with protease E, methanol, formaldehyde, periodate or urea significantly decreased (P < 0·05) the ability of heat-treated cells to remove patulin. Fourier transform infrared (FTIR) analysis indicated that more functional groups were involved in the binding process of heat-treated cells. CONCLUSIONS Polysaccharides and protein are important components of yeast cell wall involved in patulin removal. In addition, hydrophobic interactions play a major role in binding processes. SIGNIFICANCE AND IMPACT OF THE STUDY Heat-treated S. cerevisiae cells could be used to control patulin contamination in the apple juice industry. Also, our results proof that the patulin removal process is based mainly on the adsorption not degradation.

Abstract
Acute lung injury is a common complication in critically ill patients. The present study examined possible immunomodulating effects of the volatile anaesthetic sevoflurane on lipopolysaccharide (LPS)-stimulated alveolar epithelial cells (AEC) in vitro. Sevoflurane was applied after the onset of injury, simulating a "postconditioning" scenario. Rat AEC were stimulated with LPS for 2 h, followed by a 4-h co-exposure to a CO(2)/air mixture with sevoflurane 2.2 volume %; control cells were exposed to the CO(2)/air mixture only. Cytokine-induced neutrophil chemoattractant-1, monocyte chemoattractant protein-1, intercellular adhesion molecule-1, as well as the potential protective mediators inducible nitric oxide synthase (iNOS)2 and heat shock protein (HSP)-32, were analysed. Additionally, functional assays (chemotaxis, adherence and cytotoxicity assay) were performed. A significant reduction of inflammatory mediators in LPS-stimulated, sevoflurane-exposed AEC was found, leading to reduced chemotaxis, neutrophil adherence and neutrophil-induced AEC killing. While iNOS2 was increased in the sevoflurane group, blocking experiments with iNOS2 inhibitor did not affect sevoflurane-induced decrease of inflammatory mediators and AEC killing. Interestingly, sevoflurane treatment also resulted in an enhanced expression of HSP-32. The data presented in the current study provide strong evidence that anaesthetic postconditioning with sevoflurane mediates cytoprotection in the respiratory compartment in an in vitro model of acute lung injury.

Abstract
Ecological diversity refers to a combination of the richness and evenness of an investigation object. Based on this, the widely used model, Shannon model, and a recently developed model, Scaling ecological diversity model, were theoretically analyzed in this paper. It was indicated that Shannon model had many limitations, e. g., it could be available only when the number of each type of investigation object was more than 100, did not include any information of scale, and could not express the richness of diversity. In other words, Shannon model could only express the evenness of diversity. A case-study in Fukang of Xinjiang Uygur Autonomous Region showed that the richness and Shannon evenness were always resolution-dependent, while the ecotope diversity calculated by Scaling ecological diversity model was resolution-independent when the spatial resolution ranged from 30 m x 30 m to 150 m x 150 m, and strictly increased when the spatial resolution ranged from 150 m x 150 m to 480 m x 480 m.

Abstract
PURPOSE To Study the clinical, pathological, ultrastructural and immunohistchemical characters of adenoma of the retinal pigment epithelium in order to offer evidence to diagnose this tumor. METHODS Routine paraffin slices HE stain, histochemistry PAS and VG stain, transmission electron microscopy, and immunohistochemistry for S-100 and vimentin with LSAB method were used. RESULTS The tumor cells were oval and cuboidal in shape. Part of the tumor had a tubular arrangement. Around the sheets of tumors cells there was a large amount of uniform red stick-like substances. The above matter represented positive in PAS stain. Most of the above matter was yellow, while less of the matter showed red in VG stain. Transmission electron microscopy showed that there were tight junctions between tumor cells. Immunohistochemistry showed positive for S-100, negative for vimentin. CONCLUSIONS The ultrastructural and immunohistochemical characters of the adenoma of retinal pigment epithelium are consistent with the retinal pigment epithelium.

Abstract
This study investigated whether idoxifene, a selective estrogen receptor modulator (SERM), exerted protective effects against ischemia-reperfusion-induced shock. Ovariectomized rats were treated with vehicle, idoxifene, or 17beta-estradiol for 4 days. Rats were subjected to splanchnic artery occlusion (SAO) followed by reperfusion (SOA/R). In vehicle-treated rats, SAO/R resulted in hypotension, hemoconcentration, increased plasma tumor necrosis factor (TNF)-alpha levels, intestinal neutrophil accumulation, and endothelial dysfunction. 17beta-Estradiol treatment increased plasma estradiol concentration and reduced SAO/R-induced tissue injury. Idoxifene treatment had no effect on plasma estradiol concentration but reduced SAO/R-induced hemoconcentration (+8.8 +/- 1.3 vs. +14 +/- 1.3% in the vehicle group, P < 0.01), TNF-alpha production (98 +/- 3.2 vs. 214 +/- 13 pg/ml, P < 0.01), and neutrophil accumulation (0.025 +/- 0.005 vs. 0.047 +/- 0.005 U/g protein, P < 0.01). It also improved endothelial function, prolonged survival time (172 +/- 3.5 vs. 147 +/- 8 min, P < 0.01), and increased survival rate (69 vs. 23%, P < 0.01). Moreover, treatment with 17beta-estradiol or idoxifene in vivo reduced TNF-alpha-induced endothelial dysfunction in vitro. Taken together, these results demonstrated that idoxifene exerted estrogen-like, endothelial-protective, and antishock effects in ovariectomized rats, suggesting that SERMs have therapeutic potential in tissue injury resulting from ischemia-reperfusion.

Abstract
Bone morphogenetic proteins (BMPs) and their serine/threonine kinase receptors have been identified in atherosclerotic arteries and vascular smooth muscle cells, respectively. Thus, BMPs (the largest subfamily of the TGF-beta superfamily) have been implicated in the pathogenesis of atherosclerosis. However, the origins of BMP biosynthesis and the functional roles of BMP in blood vessels are unclear. The present study explored BMP-2 gene expression in various human blood vessels and vascular cell types. Functional in vitro studies were also performed to determine the effects of recombinant human BMP-2 on migration (transwell assay) and proliferation ([3H]-thymidine incorporation) of human aortic vascular smooth muscle cells (HASMC). RT-PCR experiments revealed BMP-2 gene expression in normal and atherosclerotic human arteries as well as cultured human aortic and coronary vascular smooth muscle cells, human umbilical vein endothelial cells (HUVECs) and human macrophages. In cellular migration studies, incubation with BMP-2 produced efficacious (</=610-fold), concentration- and time-dependent chemotaxis of HASMCs (EC50 = 0.8 microM) with little or no effect on HUVEC chemotaxis. The increased HASMC motility induced by BMP-2 was inhibited by coincubation with an anti-BMP-2 mAb. In addition, subthreshold concentrations of BMP-2 produced a dramatic synergistic effect upon platelet-derived growth factor (PDGF)-induced chemotaxis. In contrast to PDGF, BMP-2 had no significant effet on [3H]-thymidine incorporation in HASMC at chemotaxic concentrations (</=6.0 microM) nor did it synergize with the mitogenic effects of PDGF. In conclusion, the expression of BMP-2 by numerous cell types in the blood vessel wall may play a chemotactic or cochemotactic role in the smooth muscle cell response to vascular injury.

Abstract
An arteriovenous (AV) shunt as a method of restoring venous drainage during replantation was examined by use of the rabbit ear model. The results were compared to ears replanted using one vein (1:1) or two veins (2:1) for venous drainage. The success rate for AV shunt replantations was found similar to that of replantations with a 1:1 ratio, but lower than that of ears with a 2:1 ratio. Postoperatively, ears replanted using an AV shunt or a 1:1 ratio revealed more swelling and lower tissue oxygenation than ears with a 2:1 ratio. After 10-14 days, all ears that survived were similar in appearance, regardless of method of replantation. Microscopic venules crossing the replanted interface appeared at seven days following surgery in all groups. The authors conclude that the AV shunt method offers an alternative to venous anastomosis when vein-to-vein reconstruction cannot be established.

Abstract
From 1980 through 1990, twenty-two patients with subungual exostosis were treated in PUMC Hospital and the Sixth Hospital of Beijing. The incidence of subungual exostosis was 4.6% among all bone tumors. Post-adolescents and young adults were most commonly affected, and the female to male ratio was 1.75 to 1. The great toe was the most often involved site. Radiological findings were found to be diagnostic, and local tumor excision is the treatment of choice.
