Abstract
Objective: Randomized controlled trials (RCT) usually have strict implementation criteria. The included subjects' characteristics of the conditions for the intervention implementation are quite different from the actual clinical environment, resulting in discrepancies between the risk-benefit of interventions in actual clinical use and the risk-benefit shown in RCT. Therefore, some methods are needed to enhance the extrapolation of RCT results to evaluate the real effects of drugs in real people and clinical practice settings. Methods: Six databases (PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP) were searched up to 31st December 2022 with detailed search strategies. A scoping review method was used to integrate and qualitatively describe the included literature inductively. Results: A total of 12 articles were included. Three methods in the included literature focused on: ①improving the design of traditional RCT to increase population representation; ②combining RCT Data with real-world data (RWD) for analysis;③calibrating RCT results according to real-world patient characteristics. Conclusions: Improving the design of RCT to enhance the population representation can improve the extrapolation of the results of RCT. Combining RCT data with RWD can give full play to the advantages of data from different sources; the results of the RCT were calibrated against real-world population characteristics so that the effects of interventions in real-world patient populations can be predicted.

Abstract
Surgical treatment is one of the most important forms of treatment in patients with gallbladder cancer. With the development of minimally invasive technology, the feasibility, safety and efficacy of minimally invasive approaches such as laparoscopic or robotic-assisted radical cholecystectomy for gallbladder cancer have received continuous attention.For patients with an early T-stage (Tis or T1a), laparoscopic simple cholecystectomy is safe and economical, with a good prognosis for postoperative patients, and it has been widely accepted and performed. Radical resection of advanced gallbladder cancer requires resection of the gallbladder, its liver bed, and other neighboring invaded organs, as well as clearance of regional lymph nodes, which requires experienced gallbladder cancer treatment teams to strictly grasp the indications, select appropriate patients, and formulate a good surgical strategy to ensure the therapeutic effect. Meanwhile, robot-assisted radical resection for gallbladder cancer has been performed in a few centers and shows good clinical potential, but more high-quality studies are needed to further evaluate its value in gallbladder cancer treatment.

Abstract
Objective: To investigate the causal relationship between intestinal flora and benign biliary diseases by genome-wide Mendelian randomization. Methods: This is a retrospective observational study. The data from the genome-wide association study of the gut microbiota from 18 340 samples from the MiBioGen consortium were selected as the exposure group,and the data from the genome-wide association study of biliary tract diseases were obtained from the FinnGen consortium R8 as the outcome group. There were 1 491 cases of primary sclerosing cholangitis,32 894 cases of cholelithiasis,3 770 cases of acalculous cholecystitis,and 34 461 cases of cholecystitis. Single nucleotide polymorphisms were screened as instrumental variables,and the Mendelian randomization method was used to infer the causal relationship between exposures and outcomes. The inverse variance weighting method (IVW) was used as the main basis, supplemented by heterogeneity,pleiotropy and sensitivity tests. Results: Coprococcus 2 was associated with a reduced risk of cholelithiasis (IVW OR=0.88,95%CI:0.80 to 0.97,P=0.012) and cholecystitis (IVW OR=0.88,95%CI:0.80 to 0.97,P=0.011). Coprococcus 3 was associated with cholelithiasis (IVW OR=1.15,95%CI:1.02 to 1.30,P=0.019) and acalculous cholecystitis(IVW OR=1.48, 95%CI: 1.08 to 2.04,P=0.016) and cholecystitis (IVW OR=1.17, 95%CI: 1.02 to 1.33, P=0.020). Peptococcus was associated with an increased risk of cholelithiasis (IVW OR=1.08, 95%CI:1.02 to 1.13, P=0.005) and cholecystitis (IVW CI=1.07, 95%CI:1.02 to 1.13,P=0.010). Clostridiumsensustricto 1 was associated with an increased risk of cholelithiasis (IVW OR=1.16,95%CI:1.02 to 1.31, P=0.020) and cholecystitis (IVW OR=1.16, 95%CI:1.03 to 1.30, P=0.015). Eubacterium hallii was associated with an increased risk of primary sclerosing cholangitis (IVW OR=1.43, 95%CI: 1.03 to 1.99, P=0.033). Eubacterium ruminantium (IVW OR=0.87, 95%CI: 0.76 to 1.00, P=0.043) and Methanobrevibacter (IVW OR=0.81, 95%CI: 0.68 to 0.98, P=0.027) were associated with a reduced risk of acalculous cholecystitis. Conclusions: Eight intestinal bacterial genera maybe play pathogenic roles in benign biliary diseases. Eubacterium hallii can increase the risk of primary sclerosing cholangitis. Peptococcus and Clostridiumsensustricto 1 can increase the risk of cholelithiasis and generalized cholecystitis. Coprococcus 3 have multiple correlations with biliary stones and inflammation.

Abstract
Objective: Differences between randomized controlled trial (RCT) results and real world study (RWS) results may not represent a true efficacy-effectiveness gap because efficacy-effectiveness gap estimates may be biased when RWS and RCT differ significantly in study design or when there is bias in RWS result estimation. Secondly, when there is an efficacy- effectiveness gap, it should not treat every patient the same way but assess the real-world factors influencing the intervention's effectiveness and identify the subgroup likely to achieve the desired effect. Methods: Six databases (PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP) were searched up to 31st December 2022 with detailed search strategies. A scoping review method was used to integrate and qualitatively describe the included literature inductively. Results: Ten articles were included to discuss how to use the RCT research protocol as a template to develop the corresponding RWS research protocol. Moreover, based on correctly estimating the efficacy-effectiveness gap, evaluate the intervention effect in the patient subgroup to confirm the subgroup that can achieve the expected benefit-risk ratio to bridge the efficacy-effectiveness gap. Conclusion: Using real-world data to simulate key features of randomized controlled clinical trial study design can improve the authenticity and effectiveness of study results and bridge the efficacy-effectiveness gap.

Abstract
Chronic non-communicable diseases (NCDs) have become diseases that seriously threaten the health and quality of life of the Chinese population, and also become a major public health problem affecting the national economic and social development. With the intensification of China's population aging, the economic burden caused by NCDs will further increase. More and more evidence has shown that NCDs could be prevented, and the prevention and control of NCDs have been considered as a core task of building a healthy China. Therefore, precise personalized nutrition and the prevention of NCDs from the age of zero, which is called the "Double Zero Strategy", would provide a well-consolidated basis for body tissue structure, and prevention of NCDs should also begin at age zero, and then extend to the first 1 000 days of life. The "Double Zero Strategy" preventive intervention can improve the nutritional status, balance diet and nutrition, and increase physical activity among children, adolescents, adults, and the elderly, all of which can reduce the risk of chronic disease, disability, and death. Therefore, launching the "Double Zero Strategy" for full life cycle prevention will help to achieve China's health goals in the new era, and provide more comprehensive measures and plans for implementing the goal of a healthy China.

Abstract
Dental caries is the most common oral disease and the most common cause of resin restorations. In minimally invasive dentistry, the principle behind cavity preparation is to remove external caries-infected dentin (CID) and preserve internal caries-affected dentin (CAD) and sound dentin (SD). The cavity floor is mainly composed of CAD, but the poor bonding performance of CAD has become a widespread concern. This study evaluated the performance of a new collagen-reactive monomer (ITCM) used as a primer to improve the bonding performance of CAD. The experimental specimens were grouped as follows: SD, CAD, and ITCM-pretreated CAD (CAD-ITCM). Dentin slices were obtained for attenuated total reflectance-Fourier transform infrared (ATR-FTIR) analysis. The bonded samples were subjected to microtensile bond strength analysis after 24 h of water storage or aging by thermocycling, and the bonding interface quality was evaluated by nanoleakage assessment, interfacial nanoindentation testing, and in situ zymography. Cytotoxicity experiments with ITCM were performed. ATR-FTIR showed that the isocyanate groups in ITCM can covalently bind and form hydrogen bonds with the collagen in CAD to mediate chemical bonding. ITCM pretreatment significantly improved the bond strength of CAD (P < 0.05), reduced interfacial nanoleakage, improved the sealing of the bonding interface, enhanced the homogeneity of the hybrid layer, and inhibited matrix metalloproteinase activity. In addition, ITCM presented acceptable biocompatibility for dental restorative application. Taken together, this study reported the application of ITCM to induce collagen-based chemical bonding in the CAD bonding system, which fills the gap in strategies to improve the bonding performance of CAD immediately and after aging and has important clinical application prospects.

Abstract
Objective: To compare the application of China growth standard for children under 7 years of age (China standards) and World Health Organization child growth standards (WHO standards) in evaluating the prevalence of malnutrition in children aged 0-<6 years in China. Methods: The research data came from the national special program for science & technology basic resources investigation of China, named "2019-2021 survey and application of China's nutrition and health system for children aged 0-18 years". Multi-stage stratified random sampling was used to recruit 28 districts (regions) in 14 provinces, autonomous regions or municipalities across the country. Children (n=38 848) were physically measured and questionnaires were conducted in the guardians of the children. The indicators of stunting, underweight, wasting, overweight and obesity were evaluated by China standards and WHO standards respectively. Chi-square test was used to comparing the prevalence of each nutritional status between the two standards, as well as the comparison between the two standards by gender and age. Results: Among the 38 848 children, 19 650 were boys (50.6%) and 19 198 were girls (49.4%), 19 480 urban children (50.1%) and 19 368 rural children (49.9%). The stunting, underweight and wasting cases in the study population were 2 090 children (5.4%), 1 354 children (3.5%) and 1 276 children (3.3%) according to the China standards, and 1 474 children (3.8%), 701 children (1.8%) and 824 children (2.1%) according to the WHO standards, respectively; the above rates according to the China standards were slightly higher than those to the WHO standards (χ2=111.59, 213.14, and 99.99, all P<0.001). The overweight and obesity cases in the study population were 2 186 children (5.6%) and 1 153 children (3.0%) according to the China standards, and 2 210 children (5.7%) and 1 186 children (3.1%) according to the WHO standards, with no statistically significant differences (χ2=0.14 and 0.48, P=0.709 and 0.488, respectively). Compared to the results based on WHO standards, the China standards showed a lower prevalence of overweight and obesity in boys (χ2=14.95 and 5.85, P<0.001 and =0.016, respectively), and higher prevalence of overweight in girls (χ2=12.60, P<0.001); but there was no statistically significant differences in girls' obesity prevalence between the two standards (χ2=2.62, P=0.106). Conclusions: In general, the prevalence of malnutrition among children aged 0-<6 years based on China standards is slightly higher than that on WHO standards. To evaluate the nutritional status of children, it is advisable to select appropriate child growth standards based on work requirements, norms or research objectives.

Abstract
Objective: To explore the outcome of different treatment strategies in patients with pancreatic cancer with synchronous liver metastasis (sLMPC). Methods: A retrospective analysis of the clinical data and treatment results of 37 patients with sLMPC treated in China-Japan Friendship Hospital was performed from April 2017 to December 2022. A total of 23 males and 14 females were included,with an age(M(IQR)) of 61 (10) years (range: 45 to 74 years). Systemic chemotherapy was carried out after pathological diagnosis. The initial chemotherapy strategy included modified-Folfirinox, albumin paclitaxel combined with Gemcitabine, and Docetaxel+Cisplatin+Fluorouracil or Gemcitabine with S1. The possibility of surgical resection (reaching the standards of surgical intervention) was determined after systemic treatment,and the chemotherapy strategy was changed in the cases of failed initial chemotherapy plans. The Kaplan-Meier method was used to estimate the overall survival time and rate,while Log-rank and Gehan-Breslow-Wilcoxon tests were used to compare the differences of survival curves. Results: The median follow-up time for the 37 sLMPC patients was 39 months,and the median overall survival time was 13 months (range:2 to 64 months) with overall survival rates of 1-,3-,and 5-year of 59.5%,14.7%,and 14.7%,respectively. Of the 37 patients,97.3%(36/37) initially received systemic chemotherapy, 29 completed more than four cycles,resulting in a disease control rate of 69.4% (partial response in 15 cases,stable disease in 10 cases,and progressive disease in 4 cases). In the 24 patients initially planned for conversion surgery,the successful conversion rate was 54.2% (13/24). Among the 13 successfully converted patients,9 underwent surgery and their treatment outcomes were significantly better than those (4 patients) of those who did not undergo surgery (median survival time not reached vs. 13 months,P<0.05). Regarding the 9 patients whose conversion was unsuccessful, no significant differences were observed in median survival time between the surgical group (4 cases) and the non-surgical group (5 cases) (P>0.05). In the allowed-surgery group(n=13),the decreased in pre-surgical CA19-9 levels and the regression of liver metastases were more significant in the successful conversion sub-group than in the ineffective conversion sub-group;however, no significant differences were observed in the changes in primary lesion between the two groups. Conclusion: For highly selective patients with sLMPC who achieve partial response after receiving effective systemic treatment,the adoption of an aggressive surgical treatment strategy can significantly improve survival time;however, surgery dose not provide such survival benefits in patients who do not achieve partial response after systemic chemotherapy.

Abstract
Graph theory-based analysis describes the brain as a complex network. Only a few studies have examined modular composition and functional connectivity (FC) between modules in patients with spinal cord injury (SCI). Little is known about the longitudinal changes in hubs and topological properties at the modular level after SCI and treatment. We analyzed differences in FC and nodal metrics reflecting modular interaction to investigate brain reorganization after SCI-induced compensation and neurotrophin-3 (NT3)-chitosan-induced regeneration. Mean inter-modular FC and participation coefficient of areas related to motor coordination were significantly higher in the treatment animals than in the SCI-only ones at the late stage. The magnocellular part of the red nucleus may reflect the best difference in brain reorganization after SCI and therapy. Treatment can enhance information flows between regions and promote the integration of motor functions to return to normal. These findings may reveal the information processing of disrupted network modules.

Abstract
Persistent neurogenesis exists in the subventricular zone (SVZ) of the ventricles and the subgranular zone (SGZ) of the dentate gyrus of the hippocampus in the adult mammalian brain. Adult endogenous neurogenesis not only plays an important role in the normal brain function, but also has important significance in the repair and treatment of brain injury or brain diseases. This article reviews the process of adult endogenous neurogenesis and its application in the repair of traumatic brain injury (TBI) or ischemic stroke, and discusses the strategies of activating adult endogenous neurogenesis to repair brain injury and its practical significance in promoting functional recovery after brain injury.

Abstract
Objective: To compare the geographical differences and time trends of liver cancer incidence and mortality in different regions around the world so as to predict the future burden of liver cancer. Methods: The incidence and mortality data of liver cancer in different Human Development Index (HDI) countries from 2000 to 2020 were collected from the GLOBOCAN 2020 database. The joinpoint model and annual percent change (APC) were used to analyze the liver cancer global incidence and mortality as well as future epidemic trends from 2000 to 2020. Results: ASMR for male liver cancer was increased from 8.0/100, 000 in 2000 to 7.1/100,000 in 2015 (APC = -0.7, 95%CI: -1.2 ~ -0.3, P = 0.002), while ASMR for female liver cancer was increased from 3.0/100, 000 in 2000 to 2.8/100, 000 in 2015 (APC = -0.5, 95%CI: -0.8 ~ -0.2, P < 0.001). The ratio of male to female ASMR was 2.67:1 in 2000 and 2.51:1 in 2015, indicating a slight narrowing of the difference in mortality between men and women. In 2020, the global ASIR and ASMR for liver cancer were 9.5/100 000 and 8.7/100 000, respectively. Male ASIR and ASMR (14.1/100, 000 and 12.9/100, 000, respectively) were 2 ~ 3 times higher than females (5.2/100, 000 and 4.8/100, 000, respectively). There were significant differences between ASIR and ASMR in different HDI countries and regions (P(ASIR) = 0.008, P(ASMR) < 0.001), and the distributions of ASMR and ASIR were very similar. New cases and deaths were expected to increase by 58.6% (143,6744) and 60.9% (133, 5 375) in 2040, with the number of cases and deaths increasing by 39,7003 and 37,4208 in Asia, respectively. Conclusion: ASMR due to liver cancer worldwide has had a downward trend between 2000 and 2015. However, the latest epidemiological status and predictions of liver cancer in 2020 indicate that prevention and control will still be a major challenge globally in the next 20 years.

Abstract
BACKGROUND AND OBJECTIVE The cystic cavity and its surrounding dense glial scar formed in chronic spinal cord injury (SCI) hinder the regeneration of nerve axons. Accurate location of the necrotic regions formed by the scar and the cavity is conducive to eliminate the re-growth obstacles and promote SCI treatment. This work aims to realize the accurate and automatic location of necrotic regions in the chronic SCI magnetic resonance imaging (MRI). METHODS In this study, a method based on superpixel is proposed to identify the necrotic regions of spinal cord in chronic SCI MRI. Superpixels were obtained by a simple linear iterative clustering algorithm, and feature sets were constructed from intensity statistical features, gray level co-occurrence matrix features, Gabor texture features, local binary pattern features and superpixel areas. Subsequently, the recognition effects of support vector machine (SVM) and random forest (RF) classification model on necrotic regions were compared from accuracy (ACC), positive predictive value (PPV), sensitivity (SE), specificity (SP), Dice coefficient and algorithm running time. RESULTS The method is evaluated on T1- and T2-weighted MRI spinal cord images of 24 adult female Wistar rats. And an automatic recognition method for spinal cord necrosis regions was established based on the SVM classification model finally. The recognition results were 1.00±0.00 (ACC), 0.89±0.09 (PPV), 0.88±0.12 (SE), 1.00±0.00 (SP) and 0.88±0.07 (Dice), respectively. CONCLUSIONS The proposed method can accurately and noninvasively identify the necrotic regions in MRI, which is helpful for the pre-intervention assessment and post-intervention evaluation of chronic SCI research and treatments, and promoting the clinical transformation of chronic SCI research.

Abstract
PURPOSE Spinal cord injury (SCI) destroys the sensorimotor pathway and induces brain plasticity. However, the effect of treatment-induced spinal cord tissue regeneration on brain functional reorganization remains unclear. This study was designed to investigate the large-scale functional interactions in the brains of adult female Rhesus monkeys with injured and regenerated thoracic spinal cord. MATERIALS AND METHODS Resting-state functional magnetic resonance imaging (fMRI) combined with Granger Causality analysis (GCA) and motor behaviour analysis were used to assess the causal interaction between sensorimotor cortices, and calculate the relationship between causal interaction and hindlimb stepping in nine Rhesus monkeys undergoing lesion-induced spontaneous recovery (injured, n = 4) and neurotrophin-3/chitosan transplantation-induced regeneration (NT3-chitosan, n = 5) after SCI. RESULTS The results showed that the injured and NT3-chitosan-treated animals had distinct spatiotemporal features of brain functional reorganization. The spontaneous recovery followed the model of "early intra-hemispheric reorganization dominant, late inter-hemispheric reorganization dominant", whereas regenerative therapy animals showed the opposite trend. Although the variation degree of information flow intensity was consistent, the tendency and the relationship between local neuronal activity properties and coupling strength were different between the two groups. In addition, the injured and NT3-chitosan-treated animals had similar motor adjustments but various relationship modes between motor performance and information flow intensity. CONCLUSIONS Our findings show that brain functional reorganization induced by regeneration therapy differed from spontaneous recovery after SCI. The influence of unique changes in brain plasticity on the therapeutic effects of future regeneration therapy strategies should be considered. Key messagesNeural regeneration elicited a unique spatiotemporal mode of brain functional reorganization in the spinal cord injured monkeys, and that regeneration does not simply reverse the process of brain plasticity induced by spinal cord injury (SCI).Independent "properties of local activity - intensity of information flow" relationships between the injured and treated animals indicating that spontaneous recovery and regenerative therapy exerted different effects on the reorganization of the motor network after SCI.A specific information flow from the left thalamus to the right insular can serve as an indicator to reflect a heterogeneous "information flow - motor performance" relationship between injured and treated animals at similar motor adjustments.

Abstract
Objectives: To examine the landscape and metastases of the lymph nodes in prostatic anterior fat pad (PAFP) at radical prostatectomy (RP), and to describe the clinical characteristic of the patients with lymph node metastases in PAFP. Methods: The clinical and pathological data of 287 prostate cancer patients underwent RP from December 2019 to August 2021 in Department of Urology, Sun Yat-sen University Cancer Center were collected and analyzed retrospectively. All patients were male, aging (66±7) years (range: 42 to 83 years). The preoperative prostate-specific antigen (PSA) (M(IQR)) were 16.00(29.64) μg/L (range: 0.01 to 99.90 μg/L). There were 244 patients with localized or locally advanced prostate cancer and 43 patients with metastatic prostate cancer. All PAFP were dissected at RP routinely and were sent for pathologic analysis respectively. The PAFP was dissected from the prostate apex caudally toward the bladder neck and dissection extended to the joint of the prostate and the endopelvic fascia bilaterally. All the specimen of PAFP were examined and reported by subspecialty pathologists of genitourinary tumors. Statistical analysis was performed by Student t test, Wilcoxon rank-sum test, χ2 test or Fisher exact test. Results: There were 8.0% (23/287) patients with lymph nodes in PAFP, 3.8% (11/287) patients with PAFP lymph node metastases. Pathologically upstaged occurred in 1 patient due to the PAFP lymph node as the solitary metastatic lesion. Patients with lymph node metastases in PAFP presented higher preoperative PSA (M(IQR): 48.2(73.0) μg/L vs. 15.4(26.5) μg/L, Z=3.158, P=0.002), clinical T stage and N stage (Z=2.977, P=0.003; Z=2.780, P=0.005) and preoperative Gleason score (Z=2.205, P=0.027). Conclusions: Routine dissection of PAFP at RP and separately pathological analysis may allow more lymph nodes and lymph node metastases detection. More accurate pathological N stage may be acquired and consequently may improve the survival of patients by offering more appropriate adjuvant or salvage therapy.

OBJECTIVE To investigate the electrophysiological properties of pyramidal neurons in mouse motor cortex during the early postnatal development. METHODS Thirty-six mice were randomly divided into postnatal 1-, 2-, 3-Week and 1-, 2-,3-Month groups (n=6). Membrane properties, action potentials (AP) and spontaneous excitatory postsynaptic currents (sEPSCs) of motor cortex pyramidal neurons were recorded to evaluate the changes in the intrinsic electrophysilogical characteristics by using whole cell patch clamp. Pyramidal neurons and interneurons were distinguished according to the AP firing patterns. RESULTS Comparing with interneurons, pyramidal neurons exhibited regular spiking (RS) with smaller frequency. During the period of postnatal 1 Week-3 Months, some of the intrinsic membrane properties of motor cortex pyramidal neurons changed. Compared to the 1-Week mice, the resting membrane potential (RMP) of 2-Week decreased significantly (P<0.01), and the membrane input resistance (Rin) of 1-Month got a hyperpolarization (P<0.01), and they showed no significant change in the next period, while the membrane capacitance (Cm) showed no significant changes during the whole postnatal development. The AP dynamic properties changed significantly during this period. Compared to the 1-Week mice, the absolute value of the AP threshold and the AP amplitude of the 3-Week increased significantly (P<0.01), while the spike half width of the 2-Week decreased substantially (P<0.05), and they showed no significant change in the next period. The sEPSCs frequency and amplitude of 1- Month increased significantly compared to the 1-Week mice(P<0.01), while during the period of next 1 Month-3 Months, the amplitude and frequency showed no significant change. CONCLUSION These results suggest that the motor cortex pyramidal neurons have time-specific eletrophysilogical properties during the postnatal development. The electrophysiological properties can be used as a functional index to detect the degree of neurons maturity, and as a marker to distinguish the pyramidal neurons and interneurons.

Abstract
Objective: To analyze effects of parity on women's nutrition and health status. Methods: This study was based on the data bank of "Chinese Nutrition and Health Surveillance of Children and Adolescents Aged 0-17 years old and Lactating Mothers from 2016 to 2017". Using a multi-stage stratified random sampling method, 17 771 women at 0 to 24 months postpartum from 31 provinces in Mainland China were included in this study. Questionnaires were used to collect data on women's general demographic characteristics, parity, mode of delivery, pre-pregnancy weight, pre-delivery weight, diseases before and during pregnancy, postpartum hemorrhage. Current body height, body weight, waist circumference, and blood pressure were measured. Blood hemoglobin, blood glucose and blood lipids were detected. Pre-pregnancy BMI, gestational weight gain, postpartum weight retention, postpartum BMI, the rates of anemia, hypertension, diabetes, and dyslipidemia were calculated. Survey sample weights were calculated according to the sampling design and number of children under 2 years old from the sixth population census data of China. Effects of parity on the observational indicators after adjusting for confounding factors were analyzed by multivariate linear regression and multivariate logistic regression. Results: The age of 17 771 women was (29.5±5.0) years old, 12.2% (2 172) were over 35 but less than 40 years old, and 3.2% (563) were over 40 years old; the women with one parity, two parities, and three parities accounted for 47.3% (8 413), 48.5% (8 620) and 4.2% (738), respectively; urban women accounted for 49.9% (8 875), and rural women accounted for 50.1% (8 896). The results from multivariate linear regression showed that the pre-pregnancy BMI of women with two and three parities was 0.55 kg/m2 and 0.76 kg/m2 higher than women with one parity, respectively; the results of multivariate logistic regression showed that the OR(95%CI) of pre-pregnancy anemia was 1.45(1.04-2.02) for women with three parities compared with women with one parity, and the OR(95%CI) of anemia during pregnancy for women with two parities was 1.20(1.06-1.35) compared with women with one parity. Conclusion: Parity is associated with pre-pregnancy BMI and risk of anemia before and during pregnancy in women of reproductive age.

Abstract
Due to the lack of effective early diagnosis and treatment, gallbladder cancer(GBC) remains a malignant tumor with extremely high malignancy and poor prognosis. Therefore, high quality studies are required to break through the bottleneck in GBC diagnosis and treatment. This article reviewed the domestic and foreign GBC research published in 2021, presenting a comprehensive summary of the important advances in the field of clinical diagnosis and treatment. Latest epidemiological data and risk factors, emerging diagnostic methods of peripheral blood laboratory tests and imaging, new pathologic classification system, hot topics and controversies of surgical treatment as well as the dynamics of systemic treatment of GBC are reviewed in the article. The present findings may contribute to a more efficient means of diagnosis and treatment for GBC and hold the promise of improved outcomes for patients with GBC.

Abstract
In the past, acute hepatitis of unknown etiology in children was sporadic. However, during the last three weeks, there has been a trend of short-term outbreak around the world. As of May 3, 2022, at least 228 cases had been reported in about 20 countries and regions. The main clinical manifestations of the children included abdominal pain, diarrhea, vomiting, jaundice, and hepatomegaly. The liver functions including alanine aminotransferase and total bilirubin increased sharply. About 8.8% of the children needed liver transplantation. The etiology is not clear, but adenovirus type 41 is currently considered to be the most likely cause. Clinicians should keep alert to acute hepatitis of unknown etiology in children, strengthen epidemic surveillance, clinical treatment, and carry out necessary health education.

Abstract
Objective: To explore the therapeutic effects of transoral robotic surgery (TORS) and traditional surgical modes in oropharyngeal squamous cell carcinoma (OPSCC). Methods: The clinicopathological data of patients with oropharyngeal squamous cell carcinoma treated at Sun Yat-sen University Cancer Center from 2010 to 2018 were retrospectively analyzed. 135 cases were treated with traditional surgery (non-TORS group), while 52 cases were treated with TORS (TORS group). The prognosis of the two groups of patients were analyzed by Kaplan-Meier method and Log rank test, the influencing factors were analyzed by Cox regression model. Results: The 2-year overall survival (OS, 94.2%) and 2-year progression-free survival (PFS, 93.8%) of patients in the TORS group were better than those in the non-TORS group (71.4% and 71.4%, respectively, P<0.05). The 2-year OS (93.3%) and 2-year PFS (92.8%) of TORS group patients in T1-2 stage were better than those of non-TORS group (73.1% and 72.8%, respectively, P<0.05). The 2-year OS (95.8%) and 2-year PFS (95.2%) of patients with stage Ⅰ to Ⅱ in the TORS group were not significantly different from those in the non-TORS group (84.1% and 83.9%, respectively, P>0.05). The 2-year OS (92.9%) and 2-year PFS rate (92.7%) of patients with stage Ⅲ to Ⅳ in the TORS group were better than those in the non-TORS group (64.7% and 63.9%, respectively, P<0.05). The 2-year OS (94.4%) of HPV-positive patients in the TORS group was not significantly different from that in the non-TORS group (83.3%, P=0.222). The 2-year OS of HPV-negative patients in the TORS group (94.1%) was significantly different from that in the non-TORS group (43.7%, P<0.001). HPV status was an independent prognostic factor (P=0.008). Conclusions: TORS has a better prognosis in the treatment of oropharyngeal squamous cell carcinoma compared with the traditional treatment methods. The patients with T1-T2 can achieve better survival benefits after TORS treatment. The HPV-positive OPSCC patients has a better prognosis than that of HPV-negative OPSCC patients, and regardless of HPV status, OPSCC patients in the TORS group could obtain a better survival prognosis.

Abstract
Objective: To evaluate the indications, safety, feasibility, and surgical technique for patients with head and neck cancers undergoing transoral robotic retropharyngeal lymph node (RPLN) dissection. Methods: The current study enrolled 12 consecutive head and neck cancer patients (seven males and four females) who underwent transoral robotic RPLN dissection with the da Vinci surgical robotic system at the Sun Yat-sen University Cancer Center from May 2019 to July 2020. Seven patients were diagnosed as nasopharyngeal carcinoma with RPLN metastasis after initial treatments, 4 patients were diagnosed as thyroid carcinoma with RPLN metastasis after initial treatments, and one patient was diagnosed as oropharyngeal carcinoma with RPLN metastasis before initial treatments. The operation procedure and duration time, intraoperative blood loss volume and complications, nasogastric feeding tube dependence, tracheostomy dependence, postoperative complications, and hospitalization time were recorded and analyzed. Results: All patients were successfully treated by transoral robotic dissection of the metastatic RPLNs, none of which was converted to open surgery. RPLNs were completely resected in 10 patients, and partly resected in 2 patients (both were nasopharyngeal carcinoma patients). The mean number of RPLN dissected was 1.7. The operation duration time and intraoperative blood loss volume were (191.3±101.1) min and (150.0±86.6) ml, respectively. There was no severe intraoperative complication such as massive haemorrhage or adjacent organ injury during surgery. Nasogastric tube use was required in all patients with (17.1±10.6) days of dependence, while tracheotomy was performed in 8 patients with (11.6±10.7) days of dependence. The postoperative hospitalization stay was (8.5±5.7) days. Postoperative complications occurred in 4 patients, including 2 of retropharyngeal incision and 2 of dysphagia. During a follow-up of (6.5±5.1) months, disease-free progression was observed in all patients, 10 patients were disease-free survival and other 2 patients were survival with tumor burden. Conclusions: The transoral robotic RPLN dissection is safety and feasible. Compared with the traditional open surgical approach, it is less traumatic and safer, has fewer complications and good clinical application potentiality. The indications for transoral robotic RPLN dissection include thyroid carcinoma, oropharyngeal carcinoma, and some selected nasopharyngeal carcinoma and other head and neck cancers. Metastatic RPLNs from some nasopharyngeal carcinoma with incomplete capsule, unclear border and adhesion to the surrounding vessels are not suitable for transoral robotic RPLN dissection.

Abstract
Objective: To evaluate the therapeutic and prognostic outcomes of transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OSCC). Methods: A retrospective study of 99 OSCC patients treated with TORS in Department of Head and Neck Surgery, Sun Yat-sen University Cancer Center between April 2017 and May 2021 was conducted. There were 84 males and 15 females, with an age range of 35-85 years. Patients' clinical characteristics, including clinical staging, HPV infection status, perioperative management and postoperative adjuvant treatment, were recorded. The overall survival (OS) and progression-free survival (PFS) were analyzed. The survival outcomes were analyzed with Kaplan-Meier method and Log-rank test. Results: The hospital stay of OSCC patients with TORS was (5.3±2.9) days and the average time of postoperative nasal feeding tube indwelling was (15.2±10.8) days. Among the 99 patients, 21 (21.2%) received tracheotomy and the average time of tracheotomy tube indwelling was (11.9±11.4) days. The two-year OS and PFS in patients with follow-up over two years were 94.0% and 87.7%, respectively and the three-year OS and PFS of patients with follow-up over three years were 94.0% and 78.9%, respectively. The two-year OS and PFS were respectively 97.4% and 88.9%, for patients with stages I-II and 86.8% and 88.9% for patients with stages III-IV. HPV-negative and HPV-positive patients had respectively two-year OS (100.0% vs. 91.5%) and PFS (88.9% vs. 87.2%). There was no significantly statistical difference in survival between patients with and without adjuvant radiotherapy after TORS (82.6% vs. 90.5%, HR=0.52, 95%CI: 0.12-2.23, P=0.400). Conclusions: TORS is more suitable for the treatment of patients with early (Ⅰ-Ⅱ) or HPV-positive oropharyngeal squamous cell carcinoma, and the recovery after TORS treatment is good.

Abstract
Objective: To investigate the germline mutation status of related genes in breast cancer patients and high-risk individuals by next-generation sequencing. To analyze the correlations between homologous recombination repair (HR) pathway gene mutation status and clinicopathological characteristics of breast cancer patients. To supplement the database of breast cancer related gene mutations in Chinese population. Methods: This study is a cross-sectional study. From October 2020 to September 2021, whole blood samples were collected from 350 breast cancer patients and 49 high-risk individuals, admitted to Peking University People's Hospital and accepted genetic testing voluntarily. Germline mutations in 32 breast cancer related genes were detected by NGS. The clinicopathological characteristics, including age at the onset, family history, unilateral/bilateral tumor, Luminal typing (Luminal A subtype, Luminal B subtype, HER2-enriched subtype and triple negative breast cancer), tumor size and metastasis, were analyzed, and the correlations between HR pathway gene mutation status and clinicopathological characteristics were analyzed by Chi-squared test and Fisher's exact probability test. Results: Among 350 breast cancer patients, 64 (18.3%) cases carried gene pathogenic mutations (including pathogenic and likely pathogenic mutations), including 47 (13.4%) in BRCA1/2, 16 (4.6%) in non-BRCA1/2 genes, 1 (0.3%) in BRCA2 and FANCL. Among 49 high-risk individuals, 7 (14.3%) cases carried gene pathogenic mutations, including 6 (12.3%) in BRCA1/2 and 1 (2%) in ATM genes. BRCA1/2 pathogenic mutations were associated with age at the onset (18%, 8.7%, χ²=6.346, P=0.012), and the BRCA1/2 pathogenic mutation frequency was higher in patients diagnosed at age ≤45 years. HR pathway gene mutations (including pathogenic, likely pathogenic and uncertain significance mutations) were correlated with unilateral/bilateral tumor (49.5%, 68.4%, χ²=4.841, P=0.028) and Luminal typing (45.7%, 62.2%, 32%, 60%, χ²=12.004, P=0.007), and the HR mutation frequencies were higher in patients with bilateral tumor, Luminal B breast cancer and triple negative breast cancer (TNBC). Conclusion: The BRCA1/2 pathogenic mutation frequency in high-risk individuals is similar to that in breast cancer patients, and BRCA1/2 testing is helpful to guide breast cancer screening and prevention in high-risk individuals. Patients with early onset breast cancer, bilateral breast cancer, Luminal B breast cancer and TNBC have higher mutation frequencies of HR pathway genes, and HR pathway genes testing should be conducted as soon as possible to provide laboratory evidence for diagnosis, treatment, prognosis and risk evaluation of breast cancer.

Abstract
Objective: To study the intestinal flora specific differences with different lesional stages of metabolic (disorder) associated fatty liver disease (MAFLD), namely simple steatosis and steatohepatitis, so as to provide a new direction for MAFLD-related intestinal flora transplantation and targeted therapy. Methods: Mice were fed with normal diet, methionine-choline deficient diet (MCD) and a high-fat high-fructose diet (HFHF) for 12 weeks to construct simple steatosis and steatohepatitis models. HE and Sirius scarlet staining was performed to observe the liver pathological changes. The qPCR method was used to evaluate inflammation and liver fibrosis factors. A fully automatic biochemical analyzer was used to detect changes in liver transaminase and blood lipids. 16S rRNA sequencing method was used to observe the intestinal flora differences in the feces of each group of mice. The comparison of means between two groups was performed by t-test, and the comparison of means between multiple groups was performed by one-way analysis of variance. Kruskal-Wallis rank sum test was used for non-normally distributed data. Results: NAFLD scores were determined with pathological sections (HE and Sirius scarlet staining) of mice liver, which showed that the inflammation and liver fibrosis scores of the MCD and HFHF groups were 2.12 ± 0.18 and 1.06 ± 0.24, and 2.22 ± 0.16 and 0.46 ± 0.10, respectively. The degree of liver inflammation and fibrosis was significantly higher in the MCD than the HFHF group (P < 0.001 and P < 0.01). Lipid deposition was higher in the HFHF than the MCD group (P < 0.001), and the scores were 2.36 ± 0.17 and 1.60 ± 0.24 respectively. Simultaneously, the inflammatory [tumor necrosis factor-A (TNF-a), chemokine factor-2 (CXCL-2)] and hepatic fibrosis indicators [vascular smooth muscle actin alpha (a-SMA) and connective tissue growth factor (CTGF)] had confirmed the above-mentioned results at the transcription level. Moreover, the intestinal flora diversity was reduced (P < 0.05) in the MCD group than the HFHF group, and the Simpson and Shannon index were 0.31 ± 0.10 and 0.42 ± 0.05, and 2.03 ± 0.33 and 1.70 ± 0.28, respectively, and the differences were significant between different intestinal flora groups. The levels of Desulfovibrio, Odoribacter, and Roseburia flora were significantly increased in the HFHF than the MCD group, and the levels of Faecalibaculum, Parasutterella, Alipis, Butyricimonas_virosa, Turicibacter_sp, and Romboutsia_ilealis were significantly increased in the MCD than the HFHF group, and the difference was statistically significant (P < 0.05). Conclusion: There are significant differences in intestinal flora diversity between simple steatosis and steatohepatitis models. Therefore, clarifying the difference between the two may provide a new direction for the stage manner treatment of MAFLD.

Abstract
Although autogenous nerve transplantation is the gold standard for treating peripheral nerve defects of considerable length, it still has some shortcomings, such as insufficient donors and secondary injury. Composite chitosan scaffolds loaded with controlled release of nerve growth factor can promote neuronal survival and axonal regeneration after short-segment sciatic nerve defects. However, the effects on extended nerve defects remain poorly understood. In this study, we used chitosan scaffolds loaded with nerve growth factor for 8 weeks to repair long-segment (20 mm) sciatic nerve defects in adult rats. The results showed that treatment markedly promoted the recovery of motor and sensory functions. The regenerated sciatic nerve not only reconnected with neurons but neural circuits with the central nervous system were also reconstructed. In addition, the regenerated sciatic nerve reconnected the motor endplate with the target muscle. Therefore, this novel biomimetic scaffold can promote the regeneration of extended sciatic nerve defects and reconstruct functional circuits. This provides a promising method for the clinical treatment of extended peripheral nerve injury. This study was approved by the Animal Ethics Committee of Capital Medical University, China (approval No. AEEI-2017-033) on March 21, 2017.

Abstract
Objective: To evaluate the safety, efficacy and feasibility of transoral robotic surgery (TORS) for parapharyngeal space (PPS) neoplasms. Methods: We collected data from 7 patients with PPS neoplasm who received TORS in Sun Yat-sen University Cancer Center between May 2017 and November 2020, and patients' clinical and pathological characteristics were analysed. There were 2 men and 5 women with age ranged from 35 to 76 years. Among them, 2 patients underwent secondary surgery, 2 patients required combined transcervical approach to complete surgery, and 1 patient was suspected of ipsilateral cervical lymph node metastasis and scheduled for diagnostic TORS. The preoperative tumor size, operation time, intraoperative blood loss, postoperative bleeding, dyspnea, neurological impairment, feeding time and postoperative hospital stay were analyzed. SPSS 24.0 was used to analyze the data. Results: TORS was performed successfully with complete removal of tumors in all 7 cases. Among 6 patients with curative TORS, 5 patients received TORS with postoperative diagnoses of neurogenic tumors and 1 patient underwent TORS combined transcervical approach with postoperative disgnosis of recurrent pleomorphic adenoma; no intraoperative tumor rupture occurred; the intraoperative blood loss was 20-200 ml with a median of 40 ml; the operation time was 65.0-238.0 min with a median of 77.5 min; the oral feeding time was 3-6 days with a median of 3 days; and the postoperative hospital stay was 4.2±1.6 days. One patient presented with neck swelling 3 days after surgery, but this symptom relieved 3 days later after treatments with antibiotic, hemostasis and detumescence. One patient received diagnostic TORS, as intraoperative pathology indicating a recurrent pleomorphic adenoma, then the neoplasm got completely resected through transcervical-transparotid approach. None of 7 patients manifested with airway obstruction, bleeding or nerve injury symptoms after operation. All patients were followed for 2 to 44 months, no local recurrence or distant metastasis was found. Conclusions: TORS is a safe, effective and feasible treatment for selected PPS neoplasms, with less cosmetic impact, less trauma and blood loss, few postoperative complications, enhanced postoperative recovery and short hospital stay.

Abstract
Objective: To analyze the compliance and related factors of low-dose computed tomography (LDCT) screening among the high-risk population of lung cancer in three provinces participating in the cancer early diagnosis and early treatment program in urban areas of China. Methods: From October 2017 to October 2018, 17 983 people aged between 40 and 74 years old at high risk of lung cancer were recruited from Zhejiang, Anhui and Liaoning provinces. The basic demographic characteristics, living habits, history of the disease and family history of cancer were collected by using a cancer risk assessment questionnaire, and the data of participants examined by LDCT were obtained from the hospitals participating in the program. The screening compliance was quantified by the screening participation rate, and it was calculated as the proportion of participants completing LDCT scan among high-risk population. The related factors of LDCT screening compliance were analyzed by using a multivariate logistic regression model. Results: The age of 17 983 participants was (56.52±8.22) years old. Males accounted for 51.9% (N=9 332), and 69.5% (N=12 495) had ever smoked, including former smokers and current smokers. A total of 6 269 participants were screened by LDCT, and the screening participation rate was 34.86%. The results of multivariate logistic regression analysis showed that the age group of 50 to 69 years old, female, passive smokers, alcohol consumption, family history of lung cancer and history of chronic respiratory diseases were more likely to be screened by LDCT, while the compliance of LDCT screening in current smokers was low. Conclusions: The LDCT screening compliance of the high-risk population of lung cancer in urban areas of China still needs to be improved. Age, sex, smoking, drinking, family history of lung cancer and history of chronic respiratory disease are associated with screening compliance.

Abstract
Objective: To investigate the effect of dexmedetomidine on remifentanil-induced hyperalgesia and its underlying mechanism through a prospective cohort study. Methods: From July 2018 to July 2019, 80 patients who underwent day surgery in Taizhou Central Hospital (including patients with laparoscopic cholecystectomy and oophorocystectomy) were selected, there were 46 males and 34 females with a mean age of (28.8±4.3) years. The patients were divided into dexmedetomidine group and control group with random number table, 40 cases in each group. After anesthesia induction, the dexmedetomidine group was managed with intravenous infusion of dexmedetomidine (1 μg/kg) within 10 minutes, while the control group was treated with an equal volume of normal saline. The patient's general information and the intraoperative data were recorded. The visual analogue scale (VAS) was evaluated before the operation and 1, 6 and 12 h after the surgery. The Von Frey cilia method was conducted to determine the mechanical pain threshold of the patient's non-surgical body parts. The vein blood was extracted at the corresponding time point to evaluate the expression level of miR-183 via the RT-PCR method. The demographic and preoperative parameters were comparable between the two groups. Results: Compared with the control group, the mechanical pain threshold in the dexmedetomidine group increased significantly at 1, 6, and 12 h after surgery (all P<0.05), and the VAS score at the corresponding time point declined significantly (all P<0.05). At the same time points, the serum miR-183 levels in the dexmedetomidine group were all significantly higher than those in the control group after surgery (2.07±0.41 vs 1.68±0.60, 1.99±0.33 vs 1.74±0.54, 1.88±0.36 vs 1.67±0.54, respectively, all P<0.05). Conclusion: A perioperative dose of dexmedetomidine in day surgery can significantly improve the remifentanil-related hyperalgesia, and it may be related to up-regulation of the expression of miR-183 in the blood.

Abstract
Objective: To evaluate the effects of neuromuscular exercise therapy on joint stability of knee osteoarthritis (OA) patients. Methods: One hundred and ten patients with knee OA were enrolled in this ongoing prospective cohort study at Arthritis Clinic and Research Center, Peking University People's Hospital from September 2017 to October 2018. The treatment consisted of six-week neuromuscular exercise therapy. The participants were followed up at 6 weeks and 3 months after the therapy. The stability of the joint was evaluated by the index of knee joint stability (IKJS), which was extracted by a novel knee-aiming task combined with the multiscale entropy (MSE) analysis of the complexity of the light spot trajectories. The secondary outcomes were pain on the visual analogue scale (VAS, 0-100), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), quality of life on the Euro-quality of life-5 Dimensional (EQ-5D) VAS form, 30-second chair stand test and 40-meter walk test. One-way repeated measures ANOVA analysis was applied to compare the outcomes at baseline and 6 weeks and 3 months. Pearson partial analysis was used to investigate the correlation between the IKJS and the Kellgren-Lawrence (K/L) rate, pain and knee function. Results: Ninety-six participants ((65±8) years, 21 males, 75 females) completed 3-month follow-up. There was a significant improvement in IKJS at the 6-week visit compared with that at baseline (0.369, 95% confidence interval (CI) 0.241-0.496, P<0.001). The IKJS dropped at 3-month visit compared with 6-week visit, but was still better than that at baseline (0.178, 95%CI: 0.042-0.314, P=0.008). The correlation between IKJS and K/L rate, severity of pain, WOMAC or knee function was not significant (r=-0.131, -0.059, -0.231, 0.124, all P>0.05). There was improvement in pain VAS, WOMAC, EQ-5D-VAS, 30-second chair stand test and 40-meter walk test at 6 weeks and 3 months (all P<0.05). Conclusion: The neuromuscular exercise therapy is effective in improving the joint stability of the knee OA patients. However, the effect gradually diminished over time. In addition, neuromuscular exercise can help relieve pain, improve the function and quality of life in patients with knee OA.

Abstract
Objective: To systematically evaluate the methodology and reporting quality of colorectal cancer (CRC) screening guidelines/consensus and provide lights for drafting CRC screening guidelines in China. Methods: The literature retrieval for all the Chinese and English guidelines published before September 1st, 2020 was conducted by using Chinese/English databases, such as China National Knowledge Infrastructure, Wanfang Data, VIP, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, Guideline International Network, and supplement with the official website of multiple regions, such as the U.S. Preventive Services Task Force and American Cancer Society. We utilized The Appraisal of Guidelines for Research & Evaluation Ⅱ (AGREE Ⅱ) and Reporting Items for Practice Guidelines in Healthcare (RIGHT) approaches to assess the quality of CRC screening guidelines/consensus comprehensively. Results: After quality control, a total of 19 guidelines/consensus released by the United States, China, Australia, Canada, Britain, South Korea, and International organizations are successfully included, and strikingly, most of those belong to the United State(7). The results of the AGREE Ⅱ quality evaluation show that the average scores of scope and purpose (87.5%) and clarity of presentation (89.6%) are high. In contrast, there are deficient in stakeholder involvement (47.0%), the rigor of development (42.3%), applicability (47.5%), and editorial independence (50.2%). Among all the guidelines, there are 12 with an overall score of 50 or more, 13 with a recommendation level of "A", 2 with a rating of "B" and 4 with a rating of "C". Additionally, the RIGHT evaluation revealed that the average report rate in each field is necessary information (76.3%), background (77.0%), evidence (55.8%), recommendations (59.4%), review and quality assurance (26.3%), funding and declaration and management of interests (43.4%), other information (49.1%). Among all the guidelines, six have good reporting quality, whereas the additional 13 have general or weak evidence. Furthermore, subgroup analysis indicates that the quality of guidelines in developed countries is superior to that of China. Conclusion: The number of CRC screening guidelines/consensus is increasing gradually, and the overall quality of those is high, but the normative nature is warranted to be strengthened.

Abstract
OBJECTIVE To evaluate the efficiency of three Chinese commercial anti-Echinococcus antibody-based assays for the serodiagnosis of echinococcosis. METHODS A total of 142 sera from cystic echinococcosis patients, 89 sera from alveolar echinococcosis and 39 sera from healthy controls were sampled, and detected by kits A (ELISA), B (ELISA) and C (colloidal gold immunoassay). The routine blood testing results and biochemical parameters were compared between the cystic and alveolar echinococcosis patients, and the associations of the absorbance (A value) of the serum specific antibody detected by A and B kits with the routine blood testing results and biochemical parameters were examined in echinococcosis patients. In addition, the performance of these three assays for the serodiagnosis of echinococcosis was evaluated. RESULTS There were no significant differences between the cystic and alveolar echinococcosis patients in terms of the median white blood cell count (WBC), neutrophil count (NEU), monocyte count (MONO), basophil count (BASO), alanine aminotransferase concentration (ALT), aspirate aminotransferase concentration (AST), total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IBIL) (all P values > 0.05), and higher median lymphocyte count (LYM) and albumin levels (ALB) were detected in cystic echinococcosis patients than in alveolar echinococcosis patients (both P values < 0.05), while the median eosinophil count (EOS) was greater in the alveolar echinococcosis patients than in the cystic echinococcosis patients (P < 0.01). The A value of the serum specific antibody detected by kit A showed a linear positive correlation with WBC (rs = 0.153, P < 0.05) and EOS (rs = 0.174, P < 0.05), and a linear negative correlation with TBIL (rs = -0.134, P < 0.05) and IBIL (rs = -0.146, P < 0.05), while the A value of the serum specific antibody detected by kit B showed a linear positive correlation with WBC (rs = 0.257, P < 0.01), NEU (rs = 0.203, P < 0.01), MONO (rs = 0.159, P < 0.05), EOS (rs = 0.330, P < 0.01), ALT (rs = 0.171, P < 0.01) and AST (rs = 0.160, P < 0.05), and a linear negative correlation with ALB (rs = -0.168, P < 0.05). The overall coincidence rate, sensitivity, specificity, Youden's index and Kappa value of A, B and C kits were 86.30%, 69.63% and 91.48%; 84.42%, 64.94% and 92.21%; 97.44%, 97.44% and 87.18%; 0.82, 0.62 and 0.79; and 0.600, 0.337 and 0.750 for the diagnosis of echinococcosis, respectively. The overall coincidence rate, sensitivity, specificity and Youden's index of A, B and C kits were 84.54%, 64.64% and 71.82%; 80.99%, 55.63% and 68.31%; 97.44%, 97.44% and 87.18%; and 0.78, 0.53 and 0.56 for the diagnosis of cystic echinococcosis, respectively, while the overall coincidence rate, sensitivity, specificity and Youden's index of A, B and C kits were 92.19%, 85.16% and 85.16%; 89.89%, 79.78% and 84.27%; 97.44%, 97.44% and 87.18%; and 0.87, 0.77 and 0.72 for the diagnosis of alveolar echinococcosis, respectively. The C kit showed cross-reactions in the serodiagnosis of cystic echinococcosis and alveolar echinococcosis. There were no significant difference in the area under the receiver operating characteristic curve (ROC) between A and B kits for the diagnosis of echinococcosis (0.970 vs. 0.948, Z = 1.618, P > 0.05), and there was a high agreement between A and B kits in the diagnosis of echinococcosis (Kappa = 0.585, P < 0.01). CONCLUSIONS The three commercial anti-Echinococcus antibody-based kits exhibit a higher serodiagnostic efficiency for alveolar echinococcosis than for cystic echinococcosis. The A kit shows a high sensitivity and specificity for the diagnosis of echinococcosis, and has a relatively stable diagnostic performance and fewer influencing factors, which is suitable for the pre-surgical preliminary diagnosis and post-surgical follow-up monitoring of serum anti-Echinococcus antibody, while the C kit shows a high sensitivity and specificity for the diagnosis of echinococcosis, and is easy to perform and high in reporting rate, which is feasible for initial screening of echinococcosis.

Abstract
Objective: To compare left ventricular myocardial mechanics detected by cardiac magnetic resonance tissue tracking(CMR-TT) between patients with constrictive pericarditis(CP) and restrictive cardiomyopathy(RCM),and see if those can be used to differentiate CP from RCM patients. Methods: A total of 23 patients with CP, 20 patients with RCM, who hospitalized in Beijing Anzhen Hospital from January 2014 to April 2019 were included in this study and 25 healthy subjects served as control group, all subjects underwent cardiac magnetic resonance examination. Myocardial mechanics were evaluated by 2-dimensional(2D) and 3-dimensional(3D) CMR-TT in terms of global longitudinal strain(GLS), circumferential strain(GCS), radial strain(GRS) and the lateral wall strain to septal wall strain ratio(lateral/septal ratio) of basal, mid-cavity and apical. The diagnostic area under the receiver operating characteristic curve (ROC) was evaluated for differentiating CP from RCM. Results: Age, sex and heart rate were similar between CP and RCM patients(all P>0.05). 2D-GLS, 3D-GLS, GCS and GRS in CP and RCM groups were significantly lower than those in normal control group(all P<0.05).3D-GLS value was significantly lower in RCM patients than in CP patients(P<0.05), the area under the curve (AUC)=0.787(sensitivity 80%, specificity 78%). 3D-GCS was significantly lower in CP group than in RCM group(P<0.05), the AUC=0.737(sensitivity 80%, specificity 65%). However, there was no significant difference between CP and RCM in 3D-GRS(P>0.05). Compared with RCM, the circumferential and radial lateral/septal ratios of the basal were significantly lower in CP group than in RCM group(both P<0.05), AUC=0.737(sensitivity 70%, specificity 83%) and 0.737 (sensitivity 60%, specificity 87%), respectively. The left ventricular myocardial mechanics strain curve of the CP,RCM and normal control were different. The CP patients presented as " rapidly down-a platform" form, the RCM presented as "slowly down" form, and normal control presented as "rapidly down" form. Conclusion: Evaluating the differences in the diastolic process of left ventricular myocardium and left ventricular myocardial mechanics strain curve is helpful to differentiate CP from RCM patients.

Abstract
Objective: To investigate the characteristics of cochleo-vestibular dysfunction in patients with profound sudden deafness, and the prognosis of inner ear hemorrhage. Methods: From January 2017 to December 2018, 92 inpatients with profound sudden sensorineural hearing loss were enrolled in the Department of Otorhinolaryngology, First Affiliated Hospital of Sun Yat-sen University. Our studied patients included 47 males and 45 females, aged 20-78 (39.3±6.1) years. According to the results of inner ear magnetic resonance imaging (MRI), the patients were divided into two groups: inner ear hemorrhage group and non-inner ear hemorrhage group. The clinical features, vestibular tests and audiological examination results during follow up were compared between the two groups. SPSS 22.0 software was used for statistical analysis. Results: The inner ear hemorrhage group consisted of 32 cases (34.8%, 32/92), all of whom complained of vertigo (100%, 32/32). Simultaneous vertigo attack and hearing loss occurred in 78.1% of this group (24/32). Neither semicircular canals function, nor cervical vestibular evoked myogenic potential (c-VEMP), nor ocular vestibular evoked myogenic potential (o-VEMP) in the affected side was normal (100%, 32/32). The rates of benign paroxysmal positional vertigo (BPPV) and disequilibrium were 37.5% (12/32) and 25.0% (8/32) respectively. Hearing improved in 28.1% (9/32) two weeks after treatment, and became stable at one month's follow up. In 60 cases without inner ear hemorrhage, 58.3% of them (35/60) experienced vertigo, which occurred simultaneously with hearing loss in 21 patients (60%, 21/35). The abnormal rates of semicircular canals function, c-VEMP and o-VEMP were 71.6% (43/60), 78.3% (47/60) and 66.7% (40/60), respectively. The incidence of BPPV was 16.7% (10/60) and 8.3% (5/60) in cases with disequilibrium. Hearing improved in 58.3% (35/60) two week after treatment, and became stable at three months' follow up. Significant difference was found in either vertigo rate, or simultaneous vertigo/hearing loss rate, or abnormal c-VEMP/o-VEMP rates, or accompanying BPPV, or disequilibrium rates between the two groups (P<0.05 each). Moreover, we observed better hearing recovery in non-inner ear hemorrhage group in the two weeks, one month, three months and six months' follow up, when compared with those in inner ear hemorrhage groups (P<0.05 each). Conclusions: Inner ear hemorrhage is associated with more severe cochlea-vestibular lesion and poorer prognosis, in comparison to the non-inner ear hemorrhage,in patients with profound sudden sensorineural hearing loss.

Abstract
Emerging evidences indicate bromodomain-containing proteins 2 and 4 (BRD2 and BRD4) play critical roles in cancers, inflammations, cardiovascular diseases and other pathologies. Multiple short molecular dynamics (MSMD) simulations combined with molecular mechanics generalized Born surface area (MM-GBSA) method were applied to investigate the binding selectivity of three inhibitors 87D, 88M and 89G towards BRD2 over BRD4. The root-mean-square fluctuation (RMSF) analysis indicates that the structural flexibility of BRD4 is stronger than that of BRD2. Moreover the calculated distances between the Cα atoms in the centres of the ZA_loop and BC_loop of BRD4 are also bigger than that of BRD2. The rank of binding free energies calculated using MM-GBSA method agrees well with that determined by experimental data. The results show that 87D can bind more favourably to BRD2 than BRD4, while 88M has better selectivity on BRD4 over BRD2. Residue-based free-energy decomposition method was utilized to estimate the inhibitor-residue interaction spectrum and the results not only identify the hot interaction spots of inhibitors with BRD2 and BRD4, but also demonstrate that several common residues, including (W370, W374), (P371, P375), (V376, V380) and (L381, L385) belonging to (BRD2, BRD4), generate significant binding difference of inhibitors to BRD2 and BRD4.

Abstract
Low electronic conductivity and large volume variation result in inferior lithium storage performance of ZnO. To overcome these shortcomings of ZnO, herein ZnO nanoparticles are encapsulated in resorcinol-formaldehyde resin-derived hard carbon and then further assembled into a 3-dimensional mesoporous framework structure using a polyvinyl pyrrolidone-derived soft carbon network. The synthesis methods include the polymerization of resorcinol-formaldehyde resin and a polyvinyl pyrrolidone-boiling method. ZnO@dual carbon has af large specific surface area (153.7 m2 g-1) and high porosity. It exhibits excellent cycling performance and high rate capability. After 350 cycles at 500 mA g-1, the ZnO@dual carbon still delivers a discharge capacity of 701 mAh g-1 while the actual discharge capacity of ZnO reaches 950.9 mAh g-1. At 2 A g-1, ZnO@dual carbon delivers the average discharge capacity of 469.6 mAh g-1. The electrochemical performance of ZnO@dual carbon is remarkably superior to those of ZnO@single carbon, pure carbon and pure ZnO nanoparticles, demonstrating the superiority of the dual carbon-assembly structure. This composite structure greatly improves the structural stability of ZnO, enhances its electron conductivity and overall electron transport capacity; which facilitates electrolyte penetration and Li ion diffusion, leading to improved cycling stability and good rate capability.

Abstract
Purpose: The consequences of malnutrition include increased risk of many complications. The assessment and management of nutritional problems are essential in supportive care of patients undergoing therapy. The primary objective of the present study was to assess changes in the nutritional status in lung cancer patients who had undergone chemotherapy.Patients and methods: Preliminary and post-chemotherapy assessments of patients' nutritional status and medical characteristics were conducted using the Patient-Generated Subjective Global Assessment (PG-SGA) from July 2014 to May 2016 at Harbin Medical University Cancer Hospital. Four hundred sixty-five advanced lung cancer patients (51.8% men and 48.2% women with a mean (SD) age of 60.2 ± 9.8 years) participated in the present study. PG-SGA was assessed prior to the initiation of chemotherapy and after four cycles of chemotherapy.Results: We found that 11.4% of the patients were severely malnourished and 65.6% of the patients were moderately malnourished prior to chemotherapy. After chemotherapy, 52.9% of the patients were considered moderately malnourished, whereas 33.8% were severely malnourished. The nutritional status had deteriorated in the majority of patients. After chemotherapy, there was a rise in the prevalence of nutrition impact symptoms.Conclusions: A deteriorated nutritional status was the result of the side effects caused by chemotherapy in the patients of the present study. These findings highlight that more attention should be paid to improve the nutritional status in patients with advanced lung cancer undergoing chemotherapy, and proper nutrition education and nutritional support should be provided to these patients.

Abstract
Objective: To investigate the differences of clinicopathological features, diagnosis, treatment and prognosis between patients with extra-gastrointestinal stromal tumors (EGIST) and duodenal gastrointestinal stromal tumors (DGIST). Methods: A retrospective case - control study was performed. Case inclusion criteria: (1) tumor confirmed by histology and pathology; (2) primary tumor locating in the extra - gastrointestinal tract or duodenum; (3) without other synchronous tumors; (4) complete clinical and pathological data. Clinical data of 20 EGIST patients and 32 DGIST patients from March 2011 to September 2016 at Department of Gastrointestinal Surgery, Ruijin Hospital, Shanghai Jiaotong University School of Medicine were retrospectively collected and analyzed. The observational parameters included clinicopathological characteristics, treatment and prognosis conditions. Continuous data of abnormal distribution were expressed as median (range) and compared using the Mann-Whitney U-test. Survival curves were drawn by the Kaplan-Meier method and compared with the Log-rank test. Results: Of the 20 EGIST patients, 8 were males and 12 were females with age of 61.0 (30.0 to 86.0) years and of the 32 DGIST patients, 12 were males and 20 were females with age of 55.5 (27.0 to 70.0) years. Compared with DGIST patients, EGIST patients were older (U=188.000, P=0.012], had larger tumor size [10.0 (3.0 to 29.0) cm vs. 4.0 (1.5 to 10.0) cm, U=98.500, P<0.001] and higher ratio of high risk classification [85.0% (17/20) vs. 12.5% (4/32), χ(2)=26.870, P<0.001]. Among the 20 EGIST patients, 5 were diagnosed with distal metastasis and received imatinib (400 mg/d), and the other 15 patients underwent radical resection who were included in survival analysis. All the 32 DGIST patients underwent radical resection. The median follow-up of whole group was 43 (14 to 76) months. The 3-year recurrence/metastasis-free survival rate of 15 cases undergoing radical resection in the EGIST group was 85.6%, which was lower than that of the DGIST group (88.6%), and the difference was not statistically significant (P=0.745). There was no significant difference in the 3-year overall survival rate between the EGIST group (92.9%) and the DGIST group (100%) (P=0.271). Conclusions: As compared to DGIST, EGIST mostly occurs in those with older age, larger tumor size and higher risk grade. The prognosis of EGIST patients after radical resection is similar to that of DGIST patients.

Abstract
Objective: To investigate the clinical value of laparoscopic peritoneal dialysis catheter implantation in peritoneal chemotherapy for gastric cancer with peritoneal metastasis. Methods: From January 2019 to June 2019, the clinical data of 6 patients diagnosed as gastric cancer with peritoneal metastasis were retrospectively analyzed in the Gastrointestinal Surgery Department of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine. Five were male and 1 was female. The median age was 69.5 (28-77) years. The median body mass index (BMI) was 22.8 (19.6-23.5). All procedures were performed under general anesthesia with endotracheal intubation. The patient's body position and facility layout in the operating room were consistent with those of laparoscopic gastrectomy. The operator's position: the main surgeon was located on the right side of the patient, the first assistant stood on the left side of the patient, and the scopist stood between the patient's legs. Surgical procedure: (1) trocar location: three abdominal trocars was adopted, with one 12 mm umbilical port for the 30° laparoscope (point A). Location of the other two trocars was dependent on the procedure of exploration or biopsy as well as the two polyester cuff position of the peritoneal dialysis catheter: Usually one 5 mm port in the anterior midline 5 cm inferior to the umbilicus point was selected as point B to ensure that the distal end of the catheter could reach the Douglas pouch. The other 5 mm port was located in the right lower quadrant lateral to the umbilicus to establish the subcutaneous tunnel tract, and the proximal cuff was situated 2 cm away from the desired exit site (point C).(2) exploration of the abdominal cavity: a 30° laparoscope was inserted from 12 mm trocar below the umbilicus to explore the entire peritoneal cavity. The uterus and adnexa should be explored additionally for women. Once peritoneal metastasis was investigated and identified, primary laparoscopic peritoneal dialysis catheter implantation was performed so as to facilitate subsequent peritoneal chemotherapy. Ascites were collected for cytology in patients with ascites. (3) peritoneal dialysis catheter placement: the peritoneal dialysis catheter was introduced into the abdominal cavity from point A. Under the direct vision of laparoscopy, 2-0 absorbable ligature was reserved at the expected fixation point of the proximal cuff (point B) for the final knot closure. Non-traumatic graspers were used to pull the distal cuff of peritoneal dialysis catheter out of the abdominal cavity through point B. The 5-mm trocar was removed simultaneously, and the distal cuff was fixed between bilateral rectus sheaths at the anterior midline port site preperitoneally. To prevent subsequent ascites and chemotherapy fluid extravasation, the reserved crocheted wire was knotted. From point C the subcutaneous tunnel tract was created before the peritoneal steath towards the port site lateral to the umbilicus. Satisfactory catheter irrigation and outflow were then confirmed. Chemotherapy regimen after peritoneal dialysis catheterization: all patients began intraperitoneal chemotherapy on the second day after surgery. On the 1st and 8th day of each 3-weeks cycle, paclitaxel (20 mg/m(2)) was administered through peritoneal dialysis catheter, and paclitaxel (50 mg/m(2)) was injected intravenously. Meanwhile, S-1 was orally administered twice daily at a dose of 80 mg·m(-2)·d(-1) for 14 consecutive days followed by 7-days rest. To observe the patients' intraoperative and postoperative conditions. Results: All the procedures were performed successfully without intraoperative complications or conversion to laparotomy. No 30 day postoperative complications were observed. The median operative time was 33.5 (23-38) min. The median time to first flatus was 1(1-2) days, and the median postoperative hospital stay was 3 (3-4) days, without short-term complications within 30 days postoperatively. The last follow-up was up to July 10, 2019, and the patients were followed for 4(1-6) months. No ascites extravasation was observed and no death occurred in the 6 patients. There was no catheter obstruction or peritoneal fluid extravasation during and after chemotherapy. Conclusion: Laparoscopic peritoneal dialysis catheter implantation was safe and feasible for patients with peritoneal metastasis of gastric cancer. The abdominal exploration, tumor staging and the abdominal chemotherapy device implantation can be completed simultaneously, which could simplify the surgical approach, improve the quality of life for patients and further propose a new direction for the development of abdominal chemotherapy.

Abstract
Walking is characterized by repetitive limb movements associated with highly structured patterns of muscle activity. The causal relationships between the muscle activities and hindlimb segments of walking are difficult to decipher. This study investigated these particular relationships and clarified whether they are correlated with speed to further understand the neuromuscular control pattern. Four adult female rhesus monkeys (Macaca mulatta) were selected to record gait parameters while walking on a bipedal treadmill at speeds of 0.2, 0.8, 1.4, and 2.0 km/h. We recorded 3 ipsilateral hindlimb muscles by surface recording. In this study, we calculated the correlations between electromyography (EMG) and kinematic parameters (24 EMG*17 kinematic parameters). Of the 408 calculated coefficients, 71.6% showed significant linear correlations. Significant linear correlations were found between muscle activity, such as burst amplitudes and the integral of muscle activity, and the corresponding kinematic parameters of each joint. Most of these relationships were speed independent (91.7% of all variables). Through correlation analysis, this study demonstrated a causal association between kinematic and EMG patterns of rhesus monkey locomotion. Individuals have particular musculoskeletal control patterns, and most of the relationships between hindlimb segments and muscles are speed independent. The current findings may enhance our understanding of neuromusculoskeletal control strategies.

Abstract
Objective: To explore the possible causes and mechanisms of sudden deafness with vertigo. Methods: Between August 2016 and December 2017, 74 patients with sudden deafness and vertigo were hospitalized in the Department of Otolaryngology, First Affiliated Hospital of Sun Yat-sen University. Among them, 36 were male and 38 were female, aged 18-75 (40.5±6.5) years. According to the results of magnetic resonance imaging (MRI), the patients were divided into two groups: internal ear hemorrhage (IEH) and non-IEH (NIEH). The characteristics of deafness, vertigo, laboratory examination and follow-up results were compared between the two groups. Results: In IEH group, deafness and vertigo occurred simultaneously in 22 cases (84.6%), abnormalities of semicircular canal function, cervical vestibular evoked myogenic potential (C-VEMP), ocular vestibular evoked myogenic potential (O-VEMP) in 26 cases (100%) and benign paroxysmal positional vertigo (BPPV) in 10 cases (38.5%). The total effective rate was 19.2% (5/26) after 14 days of treatment, and 11 cases (42.3%) appeared disturbance after 180 days of treatment. The abnormal rate of lateral vestibular function, C-VEMP and O-VEMP was 69.2% (18/26), 53.8% (14/26) and 57.7% (15/26) respectively. The improvement of hearing threshold was (28.6±9.7) dB. In NIEH group, deafness and vertigo occurred simultaneously in 25 cases (52.1%). The abnormalities of semicircular canal function, C-VEMP and O-VEMP happened in 37 cases (77.1%), 34 cases (70.8%), 26 cases (54.2%), respectively, and 6 cases (12.5%) were of BPPV. The total effective rate was 52.1% (25/48) after 14 days of treatment. After 180 days of treatment, 8 cases (16.7%) were out of balance, and the abnormal rate of lateral vestibular function, C-VEMP and O-VEMP were 31.2% (15/48), 25.0% (12/48) and 20.8% (10/48) respectively. The improvement of hearing threshold was (42.5±10.3) dB. The incidence of stimulantous deafness and vertigo, vestibular dysfunction rate, BPPV incidence rate and the total effective rate after 14 days of treatment were significantly different between the two groups (all P<0.05). The vestibular and cochlear dysfunction in IEH group was more serious than that in NIEH group. After 180 days of treatment, the vestibular dysfunction rate, imbalance rate and improvement of hearing threshold in NIEH group were significantly higher than that in IEH group (all P<0.05). The recovery of vestibular and cochlear function in NIEH group was better than that in IEH group. Conclusions: Sudden deafness with vertigo can cause vestibular and cochlear dysfunction. Different etiologies may lead to different clinical features and prognosis. The vestibular and cochlear function damage caused by inner ear hemorrhage was more serious and the recovery effect was poor.

Abstract
BACKGROUND The relatively tiny spinal cord of non-human primate (NHP) causes increased challenge in diffusion tensor imaging (DTI) post-processing. This study aimed to establish a reliable correction strategy applied to clinical DTI images of NHP. METHODS Six normal and partial spinal cord injury (SCI) rhesus monkeys underwent 3T MR scanning. A correction strategy combining multiple iterations and non-rigid deformation was used for DTI image post-processing. Quantitative evaluations were then conducted to investigate effects of distortion correction. RESULTS After correction, longitudinal geometric distortion, global distortion, and residual distance errors were all significantly decreased (P < 0.05). Fractional anisotropy at the injured site was remarkably lower than that at the contralateral site (P = 0.0488) and was substantially lower than those at the adjacent superior (P = 0.0157) and inferior (P = 0.0128) areas at the same side. CONCLUSIONS Our image correction strategy can improve the quality of the DTI images of NHP thoracic cords, contributing to the development of SCI preclinical research.

Abstract
Objectives: To study the clinical characteristics of pancreatic tuberculosis, and therefore to improve the diagnosis and treatment of this disease. Methods: The clinical data of 10 patients with pancreatic tuberculosis form 1990 to 2017 were reviewed, including clinical characteristics, laboratory tests and imaging features. Results: The ten patients aged 28 to 71 (median 56) years. All of them presented varying degrees of abdominal pain and weight loss (3 to 8 kg). Hypo-echoic pancreatic masses were shown by abdominal ultra-sound in 7 cases, and cystic-solid masses with thick wall was shown by abdominal CT scan in 4 cases, but dilatation of the pancreatic duct was found in none of the 10 cases. Hemoglobin levels lower than 12 g/L were found in 6 cases, and ESR more than 20 mm/1 h was present in 7 cases. Four cases received PPD test, but only one was positive. CA19-9 was found to be higher than normal (27 IU/ml) in 3 cases (39.2 IU/ml, 125.7 IU/ml, 88.9 IU/ml respectively). Three cases received T-spot.TB tests, and all the results were positive. Seven cases received laparotomy, and the other 3 received endoscopic ultrasound-guided biopsy. Caseous necrosis and Langerhans cells were found in all the 10 cases. Nine patients were treated by 6 to 12 months' anti-tuberculosis therapies, and at 1-5 years' follow-up, 8 were cured and 1 improved. Conclusions: The manifestations of pancreatic tuberculosis were easy to be confused with other diseases, and therefore a comprehensive understanding of history and careful examinations were important for a correct diagnosis. Once the diagnosis was made, prompt standard anti-tuberculosis therapy could lead to a favorable outcome.

Methods: One hundred and ninety cases of surgically resected ESCCs and 154 normal esophageal tissues as control were collected at the First Affiliated Hospital of Zhengzhou University in 2012.Of the 190 ESCC cases including 116 male and 74 female, aged 28-82 (60.3±8.6) years, 88 cases <60 years old and 102 cases ≥60 years old. Tissue sections were immunostained for CK7, CK8/18, CK19 and p40, and the expression was evaluated and correlated with the clinicopathologic findings and outcome. Results: CK19 and p40 were expressed in 190 cases of ESCCs; with 147 cases (77.4%) and 151 cases (79.5%) showing high p40 and CK19 expression, respectively; while 43 cases (22.6%) and 39 cases (20.5%) showed low p40 and CK19 expression, respectively. The low expression groups showed more lymph node metastases and higher pTNM stages compared to the high expression groups. The high CK19 expression group showed better prognosis than the low expression group (P<0.01); p40 expression was not correlated with prognosis(P>0.05). In contrast, CK7 and CK8/18 expression was only seen in 29 cases (15.3%) and 59 cases (31.1%) of ESCCs, respectively, and their expression correlated significantly with the degree of tumor differentiation and lymph node metastasis (P<0.05). The prognosis in the CK7 negative group was better than that in the CK7 positive group. Similar results were found in CK8/18 expression. Multivariate analysis revealed that pTNM stages, low CK19 expression and CK8/18 expression were independent prognostic factors. Conclusions: Low p40 expression and the expression of CK7 and CK8/18 cannot exclude poorly-differentiated ESCCs.CK7 and CK8/18 expression and low CK19 and p40 expression in the ESCCs are associated with lymph node metastasis and poor prognosis. Decreased expression of CK19 and positive expression of CK8/18 in ESCCs are independent prognostic markers.

Abstract
Objective: To study the prevalence and characteristics of overweight and obesity among Chinese children aged 0-5 years, in 2010-2013. Methods: Data was from the'China Nutrition and Health Surveillance-0-5-Years-Old Children and Lactating Women'project in 2013. Stratified multistage cluster sampling method was used to select 55 districts/counties from 30 provinces (autonomous regions, municipalities) with the sample size of children as 32 862. Definition of overweight and obesity were according to both the WHO 2006 growth standard in children less than 5-year-old and the WHO 2007 growth reference in children of 5-years-old. Results: were calculated by complex weight based on national census from the National Bureau of Statistics in 2010. Results The overall prevalence of overweight was 8.4% among the 0-5-year-old in 2013, with 9.4% in boys and 7.2% in girls. Both of the rates from urban and rural areas were the same, as 8.4%. The prevalence rates of overweight in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups appeared as 13.0%, 11.1%, 8.3%, 6.0%, 4.8%, 3.9% and 15.9%, respectively. The rates of overweight in low, medium and high income families were 8.0%, 8.8% and 8.9%, respectively. The prevalence of obesity was 3.1% among the 0-5-year-old, with 3.6% in boys and 2.5% in girls. There was no significant difference seen in urban (3.3%) and rural areas (2.9%). The prevalence rates for obesity in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups were 5.8%, 3.8%, 2.5%, 1.6%, 1.2%, 1.3% and 7.8%, respectively. The rates of obesity in low, medium and high income families were 2.8%, 3.3% and 3.5%, respectively. Conclusion: The prevalence rates of both overweight and obesity were increasing among the 0-5-year-olds in China, suggesting that it is necessary to timely conduct the surveillance and intervention programs on overweight and obesity in this target population.

Abstract
We present a multichannel continuous-wave (CW) fiber cavity ringdown (FCRD) gas sensing method based on frequency-shifted interferometry (FSI). This scheme detects gas concentration by measuring the intensity decay rates of continuous light from different ringdown cavities in the spatial domain, unlike conventional FCRD techniques, which measure the decay rates of pulse light in the time domain. This method shares one CW light source, one slow detector, and one slow data collector. In order to illustrate the theory, acetylene gas concentration measurement in a two-channel FSI-FCRD system was experimentally conducted in the range of 0%-1%. A linear relation was established between concentration and absorption loss, which is proportional to the intensity decay rate, and the measurement resolutions of 3.871%/dB and 3.658%/dB were achieved, respectively. The results reveal that the proposed system has the advantages of low cost, high sensitivity, high precision, and good stability in multichannel gas detection.
