Abstract
OBJECTIVE Lung squamous cell carcinoma (LUSC) is associated with a low survival rate. Evidence suggests that bone morphogenetic proteins (BMPs) and their receptors (BMPRs) play crucial roles in tumorigenesis and progression. However, a comprehensive analysis of their role in LUSC is lacking. Our study aimed to explore the relationship between BMPs/BMPRs expression levels and the tumorigenesis and prognosis of LUSC. METHODS The "R/Limma" package was utilized to analyze the differential expression characteristics of BMPs/BMPRs in LUSC, using data from TCGA, GTEx, and GEO databases. Concurrently, the "survminer" packages were employed to investigate their prognostic value and correlation with clinical features in LUSC. The core gene associated with LUSC progression was further explored through weighted gene correlation network analysis (WGCNA). LASSO analysis was conducted to construct a prognostic risk model for LUSC. Clinical specimens were examined by immunohistochemical analysis to confirm the diagnostic value in LUSC. Furthermore, based on the tumor immune estimation resource database and tumor-immune system interaction database, the role of the core gene in the tumor microenvironment of LUSC was explored. RESULTS GDF10 had a significant correlation only with the pathological T stage of LUSC, and the protein expression level of GDF10 decreased with the tumorigenesis of LUSC. A prognostic risk model was constructed with GDF10 as the core gene and 5 hub genes (HRASLS, HIST1H2BH, FLRT3, CHEK2, and ALPL) for LUSC. GDF10 showed a significant positive correlation with immune cell infiltration and immune checkpoint expression. CONCLUSION GDF10 might serve as a diagnostic biomarker reflecting the tumorigenesis of LUSC and regulating the tumor immune microenvironment to guide more effective treatment for LUSC.

Abstract
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide and characterized by emphysema, small airway remodeling and mucus hypersecretion. Citrus peels have been widely used as food spices and in traditional Chinese medicine for chronic lung disease. Given that citrus peels are known for containing antioxidants and anti-inflammatory compounds, we hypothesize that citrus peel intake can suppress oxidative stress and inflammatory response to air pollution exposure, thereby alleviating COPD-like pathologies. This study aimed to investigate the efficacy of citrus peel extract, namely Guang Chenpi (GC), in preventing the development of COPD induced by diesel exhaust particles (DEPs) and its potential mechanism. DEP-induced COPD-like lung pathologies, inflammatory responses and oxidative stress with or without GC treatment were examined in vivo and in vitro. Our in vivo study showed that GC was effective in decreasing inflammatory cell counts and inflammatory mediator (IL-17A and TNF-α) concentrations in bronchoalveolar lavage fluid (BALF). Pretreatment with GC extract also significantly decreased oxidative stress in the serum and lung tissue of DEP-induced COPD rats. Furthermore, GC pretreatment effectively reduced goblet cell hyperplasia (PAS positive cells) and fibrosis of the small airways, decreased macrophage infiltration as well as carbon loading in the peripheral lungs, and facilitated the resolution of emphysema and small airway remodeling in DEP-induced COPD rats. An in vitro free radical scavenging assay revealed robust antioxidant potential of GC in scavenging DPPH free radicals. Moreover, GC demonstrated potent capacities in reducing ROS production and enhancing SOD activity in BEAS-2B cells stimulated by DEPs. GC treatment significantly attenuated the increased level of IL-8 and MUC5AC from DEP-treated BEAS-2B cells. Mechanistically, GC treatment upregulated the protein level of Nrf-2 and could function via MAPK/NF-κB signaling pathways by suppressing the phosphorylation of p38, JNK and p65. Citrus peel extract is effective in decreasing oxidative stress and inflammatory responses of the peripheral lungs to DEP exposure. These protective effects further contributed to the resolution of COPD-like pathologies.

Abstract
Objective: To establish an intelligent registration algorithm under the framework of original-mirror alignment algorithm to construct three-dimensional(3D) facial midsagittal plane automatically. Dynamic Graph Registration Network (DGRNet) was established to realize the intelligent registration, in order to provide a reference for clinical digital design and analysis. Methods: Two hundred clinical patients without significant facial deformities were collected from October 2020 to October 2022 at Peking University School and Hospital of Stomatology. The DGRNet consists of constructing the feature vectors of key points in point original and mirror point clouds (X, Y), obtaining the correspondence of key points, and calculating the rotation and translation by singular value decomposition. Original and mirror point clouds were registrated and united. The principal component analysis (PCA) algorithm was used to obtain the DGRNet alignment midsagittal plane. The model was evaluated based on the coefficient of determination (R2) index for the translation and rotation matrix of test set. The angle error was evaluated on the 3D facial midsagittal plane constructed by the DGRNet alignment midsagittal plane and the iterative closet point(ICP) alignment midsagittal plane for 50 cases of clinical facial data. Results: The average angle error of the DGRNet alignment midsagittal plane and ICP alignment midsagittal plane was 1.05°±0.56°, and the minimum angle error was only 0.13°. The successful detection rate was 78%(39/50) within 1.50° and 90% (45/50)within 2.00°. Conclusions: This study proposes a new solution for the construction of 3D facial midsagittal plane based on the DGRNet alignment method with intelligent registration, which can improve the efficiency and effectiveness of treatment to some extent.

Abstract
Objective: To evaluate the effect of health management service on hypertension patients (HMSFHP) under the framework of the Basic Public Health Service Project by using regression discontinuity design. Methods: The participants were enrolled from an observational cohort survey in 2015 and followed up was conducted in 2019. The participants with SBP 130-150 mmHg and/or DBP 80-100 mmHg in the baseline survey of the cohort in 2015 were included in the present study. Additionally, we obtained the dates of participants receiving HMSFHP and their blood pressure data from follow-up records, physical examination records and telephone interview. The participants were divided into intervention group and control group based on the cutoff points, i.e. SBP ≥140 mmHg and/or DBP ≥90 mmHg. The local linear regression model were used to estimate the effect of HMSFHP on reducing blood pressure of the participants. Results: After adjusting for age, sex and time length of receiving HMSFHP, the results of the model including participants with 80-100 mmHg for DBP in 2015 indicated that, for the participants who received HMSFHP, the DBP decreased by 6.66 mmHg from 2015 to 2019. For the participants with SBP 130-150 mmHg in 2015, the reduction estimate of the model was -6.17 mmHg, the difference was not significant (P=0.178), suggesting that receiving HMSFHP did not cause change in SBP for the participants who received HMSFHP. Conclusion: Receiving HMSFHP had effect to reduce DBP, and HMSFHP had a positive effect on the control of blood pressure in patients with hypertension.

Abstract
Objective: To determine whether the adenine base editor (ABE7.10) can be used to fix harmful mutations in the human G6PC3 gene. Methods: To investigate the safety of base-edited embryos, off-target analysis by deep sequencing was used to examine the feasibility and editing efficiency of various sgRNA expression vectors. The human HEK293T mutation models and human embryos were also used to test the feasibility and editing efficiency of correction. Results: ①The G6PC3(C295T) mutant cell model was successfully created. ②In the G6PC3(C295T) mutant cell model, three distinct Re-sgRNAs were created and corrected, with base correction efficiency ranging from 8.79% to 19.56% . ③ ABE7.10 could successfully fix mutant bases in the human pathogenic embryo test; however, base editing events had also happened in other locations. ④ With the exception of one noncoding site, which had a high safety rate, deep sequencing analysis revealed that the detection of 32 probable off-target sites was <0.5% . Conclusion: This study proposes a new base correction strategy based on human pathogenic embryos; however, it also produces a certain nontarget site editing, which needs to be further analyzed on the PAM site or editor window.

Abstract
The stomatognathic system is an organic combination of bone, dentition, joints, masticatory muscles and innervation nerves. It is an organ system for the human body to perform mastication, speech, swallowing and other important functions. Due to the complex anatomical structure of stomatognathic system and ethical limitations, it is difficult to directly measure the movement and force by using the biomechanical experimental methods. Multi-body system dynamics is an important tool to study the kinetics and force of a multi-body system, which consists of several objects with relative motion. We can use the method of multi-body system dynamics simulation in engineering to study the movement, soft tissue deformation and force transfer of this complex stomatognathic system. This paper briefly introduces the history and application methods of multi-body system dynamics and the commonly used modeling methods. The application and research progress of multi-body system dynamics modeling methods in the field of stomatology was emphatically summarized, development prospects of current research and difficulties were put forward.

Abstract
With the accumulation of research evidence and clinical experience, an increasing number of patients benefit from vascular recanalization therapies. Although successful recanalization of the occluded artery has been achieved, neurological deficits persist after endovascular treatment, which defined as"futile reperfusion". Compared with the successful recanalization, successful reperfusion predicts final infarct size and clinical outcome more accurately. At present, the known influencing factors of futile reperfusion include older age, female, high baseline National Institute of Health stroke scale (NIHSS) score, hypertension, diabetes, atrial fibrillation, reperfusion treatment strategy, large infarction core volume, and collateral circulation status. The incidence of futile reperfusion in China is significantly higher than that in western population. However, few studies focused on its mechanism and influencing factors. To date, many clinical studies have attempted to reduce the occurrence of futile recanalization regarding antiplatelet therapy, blood pressure management and treatment process improvement. However, only one effective measure has been achieved in blood pressure management: systolic blood pressure control below 120 mmHg (1 mmHg=0.133 kPa) should be avoided after successful recanalization. Therefore, future studies are warranted to promote the establishment and maintenance of collateral circulation, as well as neuroprotective therapy.

Abstract
Objective: To summarize the experience in diagnosis and treatment of 45, X Turner syndrome (TS) with gonadal Y chromosome mosaicism and bilateral gonadoblastoma (Gb) secreting human chorionic gonadotrophin(HCG). Methods: A female patient aged 5 years and 3 months was admitted to the hospital with a complaint of "enlarged breasts for 27 months, and elevated blood β-HCG for 8 months". The clinical data were summarized, and related literature up to March 2022 with the key words"Turner syndrome" "Gonadoblastoma" "Y chromosome" "human chorionic gonadotropin" "precocious" in PubMed, CNKI and Wanfang databases were reviewed. Results: The girl went to the local hospital for 2-month breast development at age of 3 years, and was found with a heart murmur diagnosed with "pulmonary venous malformation and atrial septal defect (secondary foramen type)". Surgical correction was performed. She experienced the progressive breast development, rapid linear growth and markedly advanced skeletal age, which cannot be explained by partial activation in the hypothalamic-pituitary-gonadal axis determined at the age of 3 years and 7 months in local hospital. Then whole-exome sequencing revealed chromosome number abnormality 45, X, which was confirmed by Karyotyping. At the age of 4 years and 6 months, serum β-HCG was found to be elevated (24.9 U/L) with no lesion found at the local hospital. On physical examination, she was found with breast development, pubic hair development and clitoromegaly with elevated serum testosterone (1.96 μg/L) and β-HCG (32.3 U/L). Sex determining region Y(SRY) gene was negative in peripheral blood sample. Thoracic and abdominal CT, head and pelvic magnetic resonance imaging were normal. Exploratory laparotomy confirmed the presence of a left adnexal tumor and a right fibrous streak gonad. During surgery, simultaneous samples of bilateral gonadal and peripheral venous blood were obtained and serum β-HCG, estradiol and testosteron concentrations was higher to lower from left gonadal venous blood, right gonadal venous blood, to peripheral venous blood. Bilateral gonadectomy was performed. Histopathology revealed bilateral gonadoblastomas. SRY was positive in bilateral gonadal tissues. After surgery, serum E2, testerone and β-HCG returned to normal. So far 4 cases of HCG-secreting gonadoblastoma had been reported worldwide. The phenotypes of the 4 cases were all female, with virilization or amenorrhea, and the preoperative peripheral blood β-HCG concentrations were 74.4, 5.0, 40 456.0, and 42.4 U/L, respectively. Conclusions: There is a high risk of Gb in TS with Y chromosome components. Gb is infrequently presented with breast development, and Gb associated with HCG secretion is rare. Karyotyping should be performed in a phenotypic female with masculinization, and virilization in TS indicates the presence of Y chromosome material with concurrent androgen secreting tumors.

Abstract
Skin photoaging is exogenous aging caused by long-term ultraviolet radiation, which not only affects skin appearance, but also has a close relationship with the development of skin cancer. Saponins, flavonoids, polyphenols, polysaccharides, and extracts of Chinese medicine have been found to have anti-skin photoaging effects in recent studies. Various mechanisms such as anti-oxidative stress damage, inhibition of matrix metalloproteinase expression, promotion of collagen synthesis, inhibition of inflammatory response, DNA damage repair, enhancement of cell autophagy, and inhibition of melanin synthesis can improve the symptoms of skin photoaging and delay the photoaging process. With the active ingredients of Chinese medicine for anti-skin photoaging as the entry point, the study systematically discussed the research progress of the mechanisms underlying the anti-photoaging effects of active ingredients of Chinese medicine in recent years, in order to provide theoretical reference for the development of new anti-photoaging drugs and methods.

Abstract
BACKGROUND In spite of a growing number in the use of percutaneous coronary intervention (PCI) in China, the mortality of acute myocardial infarction (AMI) has not decreased. Traditional Chinese medicine injections for Activating Blood Circulation (TCMi-ABC), equivalent effect of anticoagulation or antiplatelet, are widely used in China; however, the improvement of fatality towards AMI is unclear. Therefore, we intend to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of TCMi-ABC in treatment with AMI. METHODS Based on the "National Medical Products Administration of China," TCMi-ABC with AMI treatment indication will be selected, including Danhong injection, Sodium Tanshinone IIA Sulfonate injection, Danshen Chuanxiongqin injection, and Puerarin injection. Randomized controlled studies will be searched from as follows: PubMed, Embase, the CENTRAL in Cochrane Library, Chinese Biomedical Literature Database (SinoMed), China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang Data Knowledge Service Platform. Two researchers will work independently on literature selection, data extraction, and quality assessment. The outcomes focus on the effects of TCMi-ABC on fatality of patients with AMI in hospitalization and in the long term, the incidence of malignant arrhythmia, left ventricular ejection fraction, and adverse events. RevMan 5.4.1 software was used for mate analysis. RESULTS This study will conduct a comprehensive literature search and provide a systematic synthesis of current published data to explore the efficacy and safety of TCMi-ABC for AMI. CONCLUSION This study will provide high-quality evidence for treatment of AMI with TCMi-ABC in terms of efficacy and safety, which may help clinicians make a better complementary treatment schedule of patients with AMI.

Abstract
In order to investigate developmental coordination disorder (DCD) of kindergarten children in Zhejiang province, 200 ordinary kindergartens were randomly selected by stratified random sampling in 11 prefecture-level cities of Zhejiang Province, and 38 900 children from 1 000 classes in each grade were then randomly selected into the study from June 2019 to December 2019. The Little DCD Questionnaire and a self-designed questionnaire were used to screen the DCD of those children. There were 36 807 valid questionnaires, and 6.50% (2 391/36 807) of them were positive results. The results showed that boy, age ≤5 years, overweight or obesity, left handedness, comorbidity with motor or developmental disorders and premature infants were risk factors of DCD in children. As for parents and families, maternal gestational age<20 years, maternal overweight or obesity before pregnancy, low-middle level education of parents, direct family and low income of family were also associated with DCD in children. Therefore, it is necessary to conduct early prevention and intervention strategies targeting on identified risk factors among relevant population.

Abstract
Fluorine is one of the most interesting elements in nuclear astrophysics, where the ^{19}F(p,α)^{16}O reaction is of crucial importance for Galactic ^{19}F abundances and CNO cycle loss in first generation Population III stars. As a day-one campaign at the Jinping Underground Nuclear Astrophysics experimental facility, we report direct measurements of the essential ^{19}F(p,αγ)^{16}O reaction channel. The γ-ray yields were measured over E_{c.m.}=72.4-344 keV, covering the Gamow window; our energy of 72.4 keV is unprecedentedly low, reported here for the first time. The experiment was performed under the extremely low cosmic-ray-induced background environment of the China JinPing Underground Laboratory, one of the deepest underground laboratories in the world. The present low-energy S factors deviate significantly from previous theoretical predictions, and the uncertainties are significantly reduced. The thermonuclear ^{19}F(p,αγ)^{16}O reaction rate has been determined directly at the relevant astrophysical energies.

Abstract
Quasielastic ^{12}C(e,e^{'}p) scattering was measured at spacelike 4-momentum transfer squared Q^{2}=8, 9.4, 11.4, and 14.2 (GeV/c)^{2}, the highest ever achieved to date. Nuclear transparency for this reaction was extracted by comparing the measured yield to that expected from a plane-wave impulse approximation calculation without any final state interactions. The measured transparency was consistent with no Q^{2} dependence, up to proton momenta of 8.5 GeV/c, ruling out the quantum chromodynamics effect of color transparency at the measured Q^{2} scales in exclusive (e,e^{'}p) reactions. These results impose strict constraints on models of color transparency for protons.

Abstract
We measure ^{2}H(e,e^{'}p)n cross sections at 4-momentum transfers of Q^{2}=4.5±0.5 (GeV/c)^{2} over a range of neutron recoil momenta p_{r}, reaching up to ∼1.0 GeV/c. We obtain data at fixed neutron recoil angles θ_{nq}=35°, 45°, and 75° with respect to the 3-momentum transfer q[over →]. The new data agree well with previous data, which reached p_{r}∼500 MeV/c. At θ_{nq}=35° and 45°, final state interactions, meson exchange currents, and isobar currents are suppressed and the plane wave impulse approximation provides the dominant cross section contribution. We compare the new data to recent theoretical calculations, where we observe a significant discrepancy for recoil momenta p_{r}>700 MeV/c.

Abstract
Objectve: To evaluate the relationship of Parkinson's disease(PD) patients' sleep quality and depression with burden, quality of life, and depression of their caregivers. Methods: A total of 120 PD patients (68 males and 52 females) and their caregivers (48 males and 72 females) from Changshu Hospital Affiliated to Nanjing University of Chinese Medicine between January 2017 and June 2019 were recruited. Patients' sleep quality, depression and quality of life was evaluated. Burden, quality of life, quality of sleep, and depression of caregivers were assessed by the Caregivers Burden Questionnaire (CBI), Health Survey Brief (SF-36), Pittsburgh Sleep Quality Index (PQS1) and Hamilton Depression Scale (HAMD), meanwhile, the correlation between relevant factors was analyzed. Results: The CBI of caregivers was positively correlated with the unified Parkinson's disease rating scale (UPDRS)-Ⅲ scores of PD patients (r=0.436, P<0.05). The CBI, SF-36GH, SF-36MH, HAMD and PSQI scores of caregivers were positively correlated with Parkinson's disease sleep scale (PDSS) scores of PD patients (r=0.546, 0.762, 0.528, 0.562 and 0.522, respectively, all P<0.01). The caregiver's CBI score was positively correlated with PD patients' Epworth sleepiness score (ESS) score (r=0.442, P<0.05), and caregiver's CBI, SF-36GH, SF-36MH, HAMD, PSQI scores were positively correlated with PD patients' HAMD scores (r=0.765, 0.813, 0.635, 0.884 and 0.601, respectively, all P<0.01). The caregiver's CBI score was positively correlated with the PDQ-39 score of PD patients (r=0.834, 0.452, 0.463, 0.421 and 0.387, respectively, all P<0.05). Multiple regression analysis indicated that the caregiver's CBI score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (r=0.512, 0.645 and 0.635, respectively, all P<0.01), and the caregiver's SF-36GH score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (r=0.452, 0.682 and 0.506, respectively, all P<0.01). The caregiver's SF-36MH score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (r=0.426, 0.608 and 0.598, respectively, all P<0.01). There was significant correlations between the caregiver's HAMD score and the patient's PDSS and HAMD scores (r=0.568 and 0.496, both P<0.01), and the PSQI score of the caregiver was significantly correlated with the PDSS and HAMD scores of the patient (r=0.532 and 0.461, both P<0.01). Conclusions: This current study underscores the presence of a significant relationship of patient's sleep quality with caregiver's burden, quality of life, depression and sleep quality. Specifically, sleep quality and depression of the patients are independent predictors for burden, quality of life and sleep quality of the caregivers.

Abstract
The aim of the study was to explore the effect of lipoxin A4 (LXA4) on lung injury in sepsis rats through the p38/mitogen-activated protein kinase (MAPK) signaling pathway. Sprague-Dawley rats were used for the study. The rat model of sepsis-induced acute lung injury was established via cecal ligation (Sepsis group, n=20). LXA4 (0.1 mg/kg) was injected at 6 h after modeling (Treatment group, n=20), and a The Control group (n=20) was also set up. The 7-day survival rate was 100% in The Control group, and LXA4 raised the survival rate of rats in the Sepsis group from 40% to 60% (P<0.01). Alveolar fluid clearance (AFC) significantly declined and the wet/dry weight (W/D) ratio of lung tissues rose remarkably in the Sepsis group compared with those in the Control group, while LXA4 restored AFC and reduced the W/D ratio of lung tissues (P<0.05), suggesting that LXA4 treatment reduces lung fluids and partially enhances AFC, thus lowering the W/D ratio of lung. The total cell count, polymorphonuclear neutrophils (PMN) percentage and concentration of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in bronchoalveolar lavage fluid (BALF) were obviously increased in the Sepsis group compared with those in the Control group, while they were markedly decreased in the Treatment group (P<0.05). The activity of myeloperoxidase (MPO) in lung tissue homogenate was evidently higher in the Sepsis group than that in The Control group, while it was notably lower in the Treatment group than that in the Sepsis group after LXA4 treatment (P<0.05). Moreover, it was observed microscopically that the morphology of lung tissues was intact in the Control group. Finally, the results of Western blotting manifested that the p-p38/ MAPK protein expression was remarkably increased in the Sepsis group, indicating the activation of the p38/MAPK pathway, while it was remarkably decreased in the Treatment group, indicating the inhibited activity of the pathway (P<0.05). LXA4 has an anti-inflammatory effect on sepsis rats with lung injury, and such effect is related to the p38/MAPK signaling pathway.

Abstract
BACKGROUND Suprapancreatic lymphadenectomy is the essence of D2 radical gastric cancer surgery. The present study aimed to describe clockwise modularized laparoscopic lymphadenectomy in the suprapancreatic area. METHODS The data from gastric cancer patients who underwent surgical treatment from September 2016 to December 2018 were collected. Patients were divided into clockwise modularized lymphadenectomy (CML) and traditional open gastrectomy (OG) groups according to the surgical treatment strategy. The propensity score matching method was utilized to balance the baseline characteristics between the two groups. RESULTS Finally, 551 gastric cancer patients were included in the present study. Following propensity score matching, 106 pairs of patients in the CML group and OG group were included in the final analysis. The CML group had more total examined lymph nodes (36, IQR 28-44.74 vs. 29, IQR 29-39.5, p = 0.002) and no. 9 station nodes (2, IQR 1-5 vs. 2, IQR 1-3, p = 0.007) than the OG group. There was less intraoperative blood loss (30, IQR 20-80 ml vs. 80, IQR 50-80 ml, p < 0.001) and a longer surgical duration (262.5 min, IQR 220-303.25 min vs. 232, IQR 220-255 min, p < 0.001) in the CML group than in the OG group. The incidence of postoperative complications (19.8% vs. 16.0%, p = 0.591) and postoperative hospital stay (8, IQR 7-9 days vs. 8, IQR 7-9 days, p = 0.452) were comparable between the CML and OG groups. CONCLUSION Laparoscopic lymphadenectomy for gastric cancer surgery is technically demanding. Clockwise modularized laparoscopic lymphadenectomy in the suprapancreatic area can attain similar effects as traditional open surgery and without an increase in postoperative adverse events.

Abstract
Objective: To investigate the effect of sleep fragmentation on perioperative neurocognitive disorders (PND) and central neuroinflammation by simulating sleep patterns of postoperative patients with sleep fragmentation in aged mice. Methods: Thirty-two elderly ICR mice were randomly divided into four groups (n=8): normal group (C), surgery group (S), fragmented sleep group (F), and surgery+fragmented sleep group (D). Fragmented sleep was conducted after internal fixation of tibia fractures, cognitive function was evaluated by novel object recognition (NOR) and fear conditioning (FC) test, and changes in expression of inflammatory cytokines in hippocampus were detected by ELISA. Results: NOR test: the recognition index (RI) of mice in group C, group S, group F and group D was 0.69±0.07, 0.48±0.07, 0.54±0.10 and 0.50±0.12, respectively. The RI of mice in group S, group F and group D was significantly lower than that in group C (t=4.885, 3.521 and 4.433, all P<0.01). There was no significant difference in RI between group S and group D (t=0.967 1, P>0.05). Contextual FC test: the freezing time of mice in group C, group S, group F and group D was(21.34±6.48), (13.83±4.26), (11.50±6.25) and (6.17±4.77) s, respectively. The freezing time of mice in group S, group F and group D was significantly lower than that in group C (t=2.722, 3.566, 5.496, P<0.05 or P<0.01). The freezing time of mice in group D was significantly lower than that in group S (t=2.774, P<0.05). Cue FC test: the freezing time of mice in group C, group S, group F and group D was (74.36±17.09), (43.91±9.71), (46.34±13.43) and (24.90±14.21) s, respectively. The freezing time of mice in group S, group F and group D was significantly lower than that in group C (t=4.393, 4.043 and 7.136, all P<0.01). The freezing time of mice in group D was significantly lower than that in group S (t=2.743, P<0.05). The levels of TNF-α, IL-6 and IL-1β in hippocampus of mice in group S, F and D were significantly higher than those in group C, while the levels of TNF-α and IL-6 in hippocampus of mice in group D were significantly higher than those in group S, with statistically significant differences (P<0.05 or P<0.01). Conclusion: Postoperative fragmented sleep aggravates postoperative cognitive impairment and increases the hippocampal neuroinflammation in aged mice.

Abstract
Objective: To explore the effect of standardized surgical treatment and multidisciplinary treatment strategy on the treatment outcomes of gastric cancer patients. Methods: A single-center cohort study was carried out. Clinicopathological and long-term follow up data of primary gastric cancer patients were retrieved from the database of Surgical Gastric Cancer Patient Registry (SGCPR) in West China Hospital of Sichuan University. Finally, 4516 gastric cancer patients were included and were divided into three groups according to time periods (period 1 group: exploration stage of standardized surgical treatment, 2000 to 2006, 967 cases; period 2 group: application stage of standardized surgical treatment, 2007 to 2012, 1962 cases; period 3 group: optimization stage of standardized surgical treatment and application stage of multidisciplinary treatment strategy, 2013 to 2016, 1587 cases). Differences in clinical data, pathologic features, and prognosis were compared among 3 period groups. Follow-up information was updated to January 1, 2020. The overall follow-up rate was 88.9% (4016/4516) and median follow-up duration was 51.58 months. Survival curve was drawn by Kaplan-Meire method and compared with log-rank test. Univariate and multivariate analyses were performed by Cox proportional hazards model. Results: There were significant differences among period 1, period 2 and period 3 groups in the rates of D2/D2+ lymphadenectomy [14.4%(139/967) vs. 47.2%(927/1962) vs. 75.4%(1197/1587), χ(2)=907.210, P<0.001], in the ratio of proximal gastrectomy [19.8%(191/967) vs. 16.6%(325/1962) vs. 8.2%(130/1587), χ(2)=100.020, P<0.001], and in the median intraoperative blood loss (300 ml vs. 100 ml vs. 100 ml, H=1126.500, P<0.001). Besides, the increasing trend and significant difference were also observed in the median number of examined lymph nodes among period 1, period 2 and period 3 groups (14 vs. 26 vs. 30, H=987.100, P<0.001). Survival analysis showed that the 5-year overall survival rate was 55.3% in period 1, 55.2% in period 2 and 62.8% in period 3, and significant difference existed between period 3 and period 1 (P=0.004). The Cox proportional hazards model analysis showed that treatment period (period 3, HR=0.820, 95%CI: 0.708 to 0.950, P=0.008), postoperative chemotherapy (HR=0.696, 95%CI: 0.631 to 0.768, P<0.001) and mid-low gastric cancer (HR=0.884, 95%CI: 0.804 to 0.973, P=0.011) were good prognostic factors. Whereas old age (≥65 years, HR=1.189, 95%CI: 1.084 to 1.303, P<0.001), palliative resection (R1/R2, HR=1.538,95%CI: 1.333 to 1.776, P<0.001), large tumor size (≥5 cm, HR=1.377, 95%CI: 1.239 to 1.529, P<0.001), macroscopic type III to IV (HR=1.165, 95%CI: 1.063 to 1.277, P<0.001) and TNM stage II to IV(II/I:HR=1.801,95%CI:1.500~2.162,P<0.001;III/I:HR=3.588, 95%CI: 3.028~4.251, P<0.001; IV/I: HR=6.114, 95%CI: 4.973~7.516, P<0.001) were independent prognostic risk factors. Conclusion: Through the implementation of standardized surgical treatment technology and multidisciplinary treatment model, the quality of surgery treatment and overall survival increase, and prognosis of gastric cancer patients has been improved.

Abstract
Objective: To investigate the feasibility, efficacy and safety of endovascular reconstruction of the carotid artery with severe stenosis and extracranial distortion under proximal protection. Methods: A retrospective analysis of 21 patients with severe carotid stenosis and extracranial distortion who were admitted to the Second Affiliated Hospital of Soochow University between January 2011 and August 2017, of which 16 patients were symptomatic stenosis with acute ischemic stroke. All the patients were treated with carotid artery stenting under (CAS) proximal protection technique, and assessed with the National Institutes of Health Stroke Scale (NIHSS) before the treatment and hospital discharge. The clinical outcome and vascular morphology were followed-up regularly after the treatment. Results: Twenty-one patients were successfully completed the CAS procedure under the proximal protection technique, the average blocking time was 241.0 (232.5-261.0) seconds. Nine patients received 1block attempt, 6 patients received 2 block attempts, and the other 6 patients received 3 block attempts. Three patients experienced transient ischemic attack (TIA) during the procedure, the maximum duration of TIA was 10 minutes. In 16 patients with symptomatic stenosis, there were no significant differences in NIHSS score before CAS procedure and hospital discharge (P>0.05). The residual stenosis rate of the carotid artery after stenting was(13±6)%, compared with preoperative (87±16)%, which appeared a significant difference (t=19.948, P<0.05). All the patients had no adverse events such as myocardial infarction, recurrent ischemic stroke and death in the follow-up period. Restenosis was assessed in 6 patients by DSA or CTA and no restenosis was found. Conclusion: Endovascular reconstruction of the carotid artery with severe stenosis and extracranial distortion under proximal protection technique has been proven as a safe and effective therapy.

Abstract
Objective: To investigate the applicability of the modified memory sub-test of syndrom kurz test (SKT-M) in middle-aged and elderly Chinese. Methods: Between March 1, 2017, and October 31, 2017, at HwaMei Hospital, 132 patients receiving elective great saphenous vein high ligation and stripping operation and 96 their accompanying dependents, 55-75 years old, were randomly divided into the SKT-M group (n=121) and auditory verbal learning test -huashan version (AVLT-H) group (n=107) using random numeral method. The two groups underwent two corresponding neuropsychological tests respectively on the day before surgery and the second day after surgery. Results: There was no significant difference in the baseline characteristics and all the neuropsychological indices at the two time points between patients and dependents (P>0.05). As a consequence, the data of the patients and dependents were integrated to compare the applicability of SKT-M and AVLT-H. The "low-score" ratio of SKT-M immediate recall (2.4%) was lower than that of AVLT-H test (12.1%) (χ(2)=8.138, P<0.01). Besides, the "low-score" ratio of SKT-M delayed recall (5.7%) was also lower than that of AVLT-H test (20.5%) (χ(2)=11.167, P<0.01). The influence factors of SKT-M were less than that of AVLT-H test. However, the learning effect of SKT-M immediate recall was more significant, for its first testing sore (23.1±5.4) was significantly higher than the second one (21.9±5.1) (t=-3.971, P<0.001). Conclusion: The SKT-M has better applicability to 55-75 years old Chinese than AVLT-H test, but its learning effect should be noted.

Abstract
OBJECTIVE To study the clinical characteristics of mandibular movement and masticatory muscle function in preoperative and postoperative patients with unilateral mandibular tumors in the region of mandibular body and ramus by combining digital mandibular movement records with electromyography, and to preliminarily explore the relationship and mechanism between movement and masticatory muscle function. METHODS Six preoperative patients with tumor in unilateral body and ramus of mandible were included, and three postoperative patients with unilateral segmental resection and reconstruction of mandibular bone were included. The mandibular movement recording system and surface electromyography system were used to collect the movement trajectory of the patients' mandibular marginal movement and chewing movement, and the surface electromyography of bilateral masseter and temporalis was recorded concurrently. The surface electromyography of bilateral masseter and temporalis was collected when the patients were at relaxation and at maximal voluntary clenching (MVC). The motion trajectory was observed on the digital virtual model, and the motion amplitude and direction of mandibular marginal movements were analyzed. The characteristics of masticatory electromyogram (EMG) activity in affected and unaffected sides at relaxation, MVC and bilateral mastication were analyzed, and the asymmetry indexes and activity indexes were calculated. RESULTS The preoperative mean maximum opening of the patients was (35.20±6.87) mm. Three patients had mild mouth opening limitation, and all the patients' mouth opening trajectory was skewed to the affected side. During lateral movements, the mean range of motion of the affected side [(10.34±1.27) mm] and that of the healthy side [(6.94±2.41) mm] were significantly different. The maximum opening of the postoperative patients was (30.65±17.32) mm, and the mandibular marginal movement characteristics were consistent with those of the patients before surgery. During MVC in the preoperative patients, the median EMG activities of the masseter muscle [44.20 (5.70, 197.90) μV] and the temporalis muscle [42.15 (22.90, 155.00) μV] on the affected side were slightly lower than those of the masseter [45.60 (7.50, 235.40) μV] and the temporalis muscle [63.30 (44.10, 126.70) μV] on the healthy side. In the postoperative patients, individualized changes occurred. Some patients suffered from weakened electromyographic activity on the affected side, while some other ones showed hyperelectromyographic activity on the affected side. CONCLUSION Both benign and malignant tumors as well as their surgery can cause abnormal mandibular movements and change of electromyographic activity of bilateral masseter and temporalis muscles.

Abstract
Objective: To investigate the effect of positive end-expiratory pressure(PEEP) on the cross-sectional area (CSA) of the internal jugular vein (IJV) and anatomic relationship between the IJV and the common carotid artery (CCA) in general anaesthesia of laryngeal mask airway(LMA). Methods: Sixty American Society of Anesthesiologists (ASA) Ⅰ or Ⅱ grade patients undergoing elective operation received general anaesthesia using LMA from May to November 2017, aged 20-65, were included in this study and randomly divided into 4 groups: group P0 (PEEP: 0 cmH(2)O), group P5 (PEEP: 5 cmH(2)O), group P10 (PEEP: 10 cmH(2)O), group P15 (PEEP: 15 cmH(2)O). Following the induction of anesthesia, LMA was inserted, and mechanical ventilation was started while the right cervical vessels was imaged by ultrasonography after applying 4 different PEEPs in random order. Measurements were made after 1 min in each PEEP. The CSA, transverse diameter (TD), anteroposterior diameters (AD) of the IJV and the diameter, overlap distance and overlap index of CCA was measured. The arterial blood pressure, heart rate, and vasoactive drugs used were also recorded. Results: The CSA of group P0, P10 and P15 was (1.36±0.55), (1.80±0.54), (2.02±0.58) cm(2). The TD was (1.31±0.33), (1.61±0.49), (1.74±0.53) cm. The AD was (1.12±0.20), (1.33±0.30), (1.46±0.32) cm. Compared to group P0, the CSA, TD and AD of IJV in group P10 and P15 were significantly increased (P0/P10: t=7.81, 3.81, 4.30, all P<0.01; P0/P15: t=11.68, 5.40, 6.96, all P<0.01). There was no significant difference in the AD and TD of IJV between group P10 and P15 (all P>0.05), while the CSA of group P15 was bigger than that of group P10 (t=2.17, P<0.05). The overlap distance of group P0, P10 and P15 was (0.51±0.12), (0.62±0.16), (0.66±0.15) cm. The overlap index was (76.80±20.03)%, (91.10±26.13)%, (96.21±25.36)%. Compared to group P0, the overlap distance and overlap index in group P10 and P15 were significantly increased (P0/P10: t=4.49, 3.41, both P<0.01; P0/P15: t=5.91, 4.63, both P<0.01). There was no significant changes in the overlap distance and overlap index between group P10 and P15 (all P>0.05). The MAP of group P15 was lower than that of group P10 [(73.35±9.73 )vs (67.58±12.58) mmHg, t=2.745, P<0.05]. No patients were given atropine or norepinephrine. Conclusions: The application of PEEP effectively increases the CSA of IJV in general anaesthesia of LMA. At the same time, it also lead to higher overlap index between the IJV and CCA.Ten cmH(2)O PEEP provides the best balance between the increase of CSA and the stability of haemodynamics.

Abstract
Objective: To explore the effects of lappaconitine on intraoperative administration of remifentanil induced postoperative hyperalgesia in general anaesthesia patients. Methods: One hundred and twenty patients from March to October 2016 undergoing elective thyroid operation under general anaesthesia at Ningbo NO.2 hospital, American Society of Anesthesiologists(ASA) Ⅰ or Ⅱ grade, aged 20-60, were enrolled in this study and randomly assigned to 3 groups (n=40). Remifentanil was intraoperatively infused at 0.1 μg·kg(-1)·min(-1) (Group S) or 0.3 μg·kg(-1)·min(-1) (Groups L and G), and patients in group G received lappaconitine 8 mg 30 minutes before the ending of surgery. Mechanical pain thresholds, visual analogue scale (VAS) and additional analgesics were recorded at 2, 6 and 24 hours after the operation. Results: There was no significant difference among the VAS and additional analgesics in three groups at 2, 6 and 24 h after operation (all P>0.05). There was no significant difference among the mechanical pain thresholds in three groups before and 2 h after operation (all P>0.05). The mechanical pain thresholds of group S, L and G was (45.7±15.6), (35.8±15.0), (47.6±16.4)g at 6 h and (50.7±17.0), (33.7±14.0), (49.7±13.9 )g at 24 h after operation. There was significant difference among the mechanical pain thresholds in group S, L and G at 6 h and 24 h after operation (F=6.586, 16.089, all P<0.01). Compared to group S, the mechanical pain thresholds significantly decreased in group L at 6 h and 24 h after operation (q=2.837, 5.045, all P<0.01). While there was a significantly increase in pain thresholds at 6 h and 24 h postoperatively in group G, as compared with the group L (q=3.384, 4.770, all P<0.01). Conclusion: Lappaconitine significantly alleviated intraoperative administration of remifentanil induced postoperative hyperalgesia in general anaesthesia patients.

Abstract
Whey protein is associated with improvement of metabolic syndrome. This study aimed to evaluate effects of whey protein on atherosclerosis in ApoE-/- mice. Male ApoE-/- mice were fed with a high-fat/cholesterol diet (HFCD), or HFCD supplemented with 10% or 20% whey protein for 18 wk. At the end of experiment, serum lipid profiles and inflammatory cytokines were assayed. Livers were examined using HE staining and Oil Red O staining. Aortas were used for en face and cryosection analyses to observe aortic lesions. Western blotting analysis was used to assess relative protein expression of cholesterol metabolism in the liver and aorta. No significant differences were observed in body weight or food intake among the three groups. Liver examination demonstrated decreased lipid droplets and cholesterol content in the whey-protein-supplemented groups. En face lesion of the aorta revealed a 21.51% and 31.78% lesion reduction in the HFCD supplemented with 10% and 20% whey groups, respectively. Decreased lesion was also observed in cryosection analysis. Whey protein significantly increased the serum high-density lipoprotein cholesterol level by 46.43% and 67.86%. The 20% whey protein significantly decreased serum IL-6 (a proinflammatory cytokine) by 70.99% and increased serum IL-10 (an anti-inflammatory cytokine) by 83.35%. Whey protein potently decreased lipogenic enzymes (ACC and FAS) in the liver and NF-κB expression in the liver and aorta. Whey protein significantly increased protein expression of two major cholesterol transporters (ABCA1 and ABCG1) in the liver and aorta. Thus, chronic whey protein supplementation can improve HFCD-induced atherosclerosis in ApoE null mice by regulating circulating lipid and inflammatory cytokines and increasing expressions of ABCA1 and ABCG1.

Abstract
The role of extranodal metastasis (ENM) in TNM stage in gastric carcinoma (GC) is controversial. This study was aimed to make a detailed investigation of the prognostic significance and the role in TNM stage of ENM in GC. The patients with primary GC, who underwent gastrectomy with curative intention in West China Hospital from January 2005 to December 2011, were retrospectively enrolled. The prognosis and clinicopathological traits were compared between ENM positive (ENMP) and negative (ENMN) groups in all patients, TNM I-II, III and IV stages, respectively. The significance of the number and the role in TNM stage of ENM were also assessed. In our study, 1457 patients were enrolled, with 1324 (90.9%) in ENMN group and 133 (9.1%) in ENMP group. ENMP group had significantly more advanced GC and worse prognosis (all p<0.05) than ENMN group in all patients, TNM I-II stages and TNM III stage. ENM>2 subgroup had remarkably larger tumor size (p=0.002) and more advanced N stage (p=0.016) than ENM=1-2 subgroup. The number of ENM was an independent prognostic factor in ENMP group (p=0.029). The prognosis of ENM>2 in TNM I-III stages was significantly worse than ENMN patients in TNM III stage. The C-index of TNM stage plus the number of ENM was significantly higher than that of current TNM stage alone (p=0.005). In conclusion, the patients in ENMP subgroup had more advanced GC and worse prognosis than those in ENMN subgroup. It might be more reasonable to categorize ENM>2 into TNM IV stage.

Abstract
The relationship of altered DNA 5'-hydroxymethylation in human spermatozoa with seminal parameters remains unclear. The aim of the study was to investigate the association between the 5'-hydroxymethylcytosine (5hmC) rate in the promoters of acetylcholinesterase (AChE) and homeobox C4 (HoxC4) genes and human sperm concentration/motility. The study population consisted of three groups: asthenozoospermia (AZ), oligoasthenozoospermia (OAZ) and normozoospermia (NZ). The 5hmC rate in the promoter was measured by CCGG loci-dependent MspI/HpaII restriction mapping of glycosylation-modified sperm DNA combined with a hydroxymethylation-specific real-time polymerase chain reaction assay. The 5hmC rate in the AChE promoter in group AZ and OAZ was higher than that in group NZ (p < .05). A weak inverse correlation between 5hmC rate of AChE and sperm motility was observed in all subjects (r = -.172, p < .05). The 5hmC rate in the HoxC4 promoter in group OAZ was lower than that in group NZ (p < .05). These results indicated that altered 5hmC rates of AChE and HoxC4 promoters are associated with low sperm motility and sperm concentration respectively.

Abstract
This study aimed to evaluate the prognostic significance of node ratio (Nr), the ratio of metastatic to retrieved lymph nodes, and to investigate whether a modified staging system based on Nr can improve prognostic ability for gastric cancer patients following gastrectomy. A total of 2572 patients were randomly divided into training set and validation set, and the cutoff points for Nr were produced using X-tile. The relationships between Nr and other clinicopathologic factors were analyzed, while survival prognostic discriminatory ability and accuracy were compared among different staging systems by AIC and C-index in R program. Patients were categorized into four groups as follows: Nr0, Nr1: 0.00–0.15, Nr2: 0.15–0.40 and Nr3: > 0.40. Nr was significantly associated with clinicopathologic factors including macroscopic type, tumor differentiation, lymphovascular invasion, perineural invasion, tumor size, T stage, N stage and TNM stage. Besides, for all patients, Nr and TNrM staging system showed a smaller AIC and a larger C-index than that of N and TNM staging system, respectively. Moreover, in subgroup analysis for patients with retrieved lymph nodes < 15, Nr was demonstrated to have a smaller AIC and a larger C-index than N staging system. Furthermore, in validation analysis, Nr, categorized by our cutoff points, showed a larger C-index and a smaller AIC value than those produced in previous studies. Nr could be considered as a reliable prognostic factor, even in patients with insufficient (< 15) retrieved lymph nodes, and TNrM staging system may improve the prognostic discriminatory ability and accuracy for gastric cancer patients undergoing radical gastrectomy.

Abstract
(1) Background: Dietary fiber intake may provide beneficial effects on the components of metabolic syndrome (MetS); however, observational studies reported inconsistent results for the relationship between dietary fiber intake and MetS risk. We conducted a meta-analysis to quantify previous observational studies and a narrative review to summarize mechanisms involved in the potential relationship. (2) Methods: The literature was searched on PubMed and Web of Science until 28 November 2017. A random-effects model was used to calculate the summary risk estimates. Eleven cross-sectional studies and three cohort studies were included in the meta-analysis. Results from the original studies were reported as odds ratios (ORs) or relative ratios (RRs) of the MetS associated with different levels of dietary fiber intake, and the ORs/RRs comparing the highest with lowest categories of the intake were pooled. (3) Results: For the cross-sectional studies, the pooled OR was 0.70 (95% confidence interval (CI): 0.61-0.82) with evidence of high heterogeneity (I² = 74.4%, p < 0.001) and publication bias (p for Egger's test < 0.001). After removing four studies, results remained significant (OR = 0.67, 95% CI: 0.58-0.78) and the heterogeneity was largely reduced (I² = 32.4%, p = 0.181). For the cohort studies, the pooled RR was 0.86 (95% CI: 0.70-1.06). (4) Conclusion: Although the meta-analysis suggests an inverse association between dietary fiber intake and risk of MetS, and the association was supported by a wide range of mechanism studies, the findings are limited by insufficient cohort data. More prospective studies are needed to further verify the association between dietary fiber intake and the risk of MetS.

Abstract
Capillary invasion (CI) has been found to play an important role in metastasis and recurrence of gastric adenocarcinoma (GAC). However, the prognostic significance of CI is still controversial. From January 2005 to December 2011, 1398 patients with GAC who underwent gastrectomy were retrospectively enrolled and divided into CI (+) and CI (−) groups. Clinicopathological features and survival outcomes were compared between these groups. In our study, 227 (16.2%) patients were CI (+). Patients with CI (+) had significantly more advanced tumors and worse prognosis than those with CI (−) (p < 0.001). CI was demonstrated as an independent prognostic factor (p = 0.023) in patients with GAC. When stratified by TNM stage, the prognosis of CI (+) group in stage III was remarkably worse than CI (−) group (p = 0.006), while the differences were not significant in stage I–II and stage IV (both p > 0.05). The nomograms indicated that CI was part of the individual prognostic prediction system. The predictive accuracy of CI and other characteristics was better than TNM alone (p < 0.001). Our finding suggested that CI was an independent prognostic factor in patients with GAC, and the nomogram based on CI and other clinicopathological factors was a valuable and accurate tool in individual prognostic prediction.

Abstract
Objective: To investigate the influence of aluminum chloride (AlCl(3)) solution on the embryon-ic development of zebrafish and neurobehavior of juvenile fish. Methods: The embryos of zebrafishat 6 hours after fertilization were exposed to AlCl(3) solution at a concentration of 0, 55.0, 60.5, 66.6, 73.5, 80.5, or 100.0 mg/L, and embryonic hatching rates at 48 and 72 hours after fertilization were calculated. The embryos of zebrafishat 6 hours after fertilization were exposed to AlCl(3) solution at a concentration of 0, 60.0, 72.0, 86.4, 103.7, or 124.4 mg/L, and the embryonic mortality rates at 12, 24, 48, 72, and 96 hours after fertilization were calculat-ed. The embryos of zebrafish at 6 hours after fertilization were exposed to AlCl(3) solution at a concentration of 0, 50, 100, 200, 400, or 800 μg/L, and the changes in the neurobehavior of juvenile fish were observed after hatching, including touch-escape reaction at 72 hours after fertilization and autonomic movement and panic es-cape reflex at 7 days after fertilization. Results: Compared with the 0 mg/L group, the≥66.6 mg/L group had a sig-nificant reduction in embryonic hatching rate at 48 and 72 hours after fertilization, and the ≥72.0 mg/L group had a significant increase in embryonic mortality rate at 96 hours after fertilization (P<0.05) . Compared with the 0 μg/L group, the≥100 μg/L group had a significant reduction in the number of times of touch-escape reaction (P<0.05) .Compared with the 0 and 50 μg/L groups, the 100-800 μg/L groups had significant reductions in total movement distance and average speed (P<0.05) . Compared with the dark period before illumination, all groups had a significant increase in movement speed during the light period of the panic escape reflex test (i.e., the third minute) (P<0.05) ; within 2 minutes after the light was turned off, there was no significant change in movement speed in the 0-200 μg/L groups (P>0.05) ; the 400 and 800 μg/L groups had a significant increase in movement speed (P<0.05) . Conclusion: AlCl(3) exposure may cause embryonic developmental disorder in zebrafish and ab-normal neurobehavior in juvenile fish.

Abstract
BACKGROUND Various factors may affect the clinical prognosis of lymph node-negative gastric cancer (GC) patients. This study aimed to provide evaluable prognostic information of combination of tumor size (Ts), lymph nodes count (LNs) and lymphovascular invasion (LVI) in lymph node-negative GC patients. METHODS A total of 1,019 node-negative GC patients were enrolled in this retrospective study from 2000 to 2010. The cutoff points of Ts and LNs were determined using X-tile and patients were randomly categorized into training and validation sets by the sample size ratio 1:1. The clinicopathologic characteristics were analyzed and survival prognostic factors were identified, whereas the survival prediction accuracy was also compared by C-index during the different independent prognostic factors. RESULTS The cutoff points for Ts were 3cm and 5cm, while 14 was the cutoff point for LNs. Age, T stage, Ts, LNs and LVI were identified as independent prognostic factors in node-negative GC patients, and a new prognostic predictive model, TsNL staging system which was composed of Ts, LNs and LVI, was proposed in this study. Compared with T staging system, significant improvement of predictive accuracy for TsNL system was found. Furthermore, nomogram based on TsNL was more accurate in prognostic prediction than that based on Ts, LNs and LVI, separately. CONCLUSIONS Age, T stage, Ts, LNs and LVI were independent prognostic factors in lymph node-negative GC patients. The TsNL staging system, composed of Ts, LNs and LVI, which was closely associated with clinicopathologic features, may improve the prognostic prediction accuracy in node-negative GC patients.

Abstract
Nutritional and immune status is important to the prognosis of patients with gastric carcinoma (GC). Here, we evaluated the prognostic significance of the combination of preoperative hemoglobin, albumin, lymphocyte and platelet (HALP) in patients with GC. From January 2005 to December 2011, 1332 patients with GC who underwent gastrectomy were randomly divided into the training (n = 888) and the validation sets (n = 444) by X-tile according to the sample size ratio 2:1. The cut-point of HALP was 56.8 and the patients were subsequently subdivided into HALP < 56.8 and HALP ≥ 56.8 groups in both two sets. Multivariate analysis revealed that gender (p < 0.001, p < 0.001), tumor size (p = 0.003, p = 0.035) and T stage (p < 0.001, p = 0.044) were independently related to HALP both in the training and the validation sets. Kaplan-Meier (p < 0.001, p = 0.003) and Cox regression (p = 0.043, p = 0.042) showed that the prognosis of HALP ≥ 56.8 group was significantly better than that of HALP < 56.8 group both in two sets (p < 0.001, p < 0.001). Nomograms of these two sets based on HALP was more accurate in prognostic prediction than TNM stage alone. Our findings suggested that HALP was closely associated with clinicopathological features and was an independent prognostic factor in GC patients. Nomogram based on HALP could accurately predict the prognosis of GC patients.

Abstract
Predicting lymph node metastasis (LNM) accurately is of great importance to formulate optimal treatment strategies preoperatively for patients with early gastric cancer (EGC). This study aimed to explore risk factors that predict the presence of LNM in EGC. A total of 697 patients underwent gastrectomy enrolled in this study, were divided into training and validation set, and the relationship between LNM and other clinicopathologic features, preoperative serum combined tumor markers (CEA, CA19-9, CA125) were evaluated. Risk factors for LNM were identified using logistic regression analysis, and a nomogram was created by R program to predict the possibility of LNM in training set, while receiver operating characteristic (ROC) analysis was applied to assess the predictive value of the nomogram model in validation set. Consequently, LNM was significantly associated with tumor size, macroscopic type, differentiation type, ulcerative findings, lymphovascular invasion, depth of invasion and combined tumor marker. In multivariate logistic regression analysis, factors including of tumor size, differentiation type, ulcerative findings, lymphovascular invasion, depth of invasion and combined tumor marker were demonstrated to be independent risk factors for LNM. Moreover, a predictive nomogram with these independent factors for LNM in EGC patients was constructed, and ROC curve demonstrated a good discrimination ability with the AUC of 0.847 (95% CI: 0.789-0.923), which was significantly larger than those produced in previous studies. Therefore, including of these tumor markers which could be convenient and feasible to obtain from the serum preoperatively, the nomogram could effectively predict the incidence of LNM for EGC patients.

Abstract
Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma. This retrospective study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in patients with PGL.From January 2003 to November 2014, 165 patients who were diagnosed with PGL at West China Hospital were enrolled in this study. The clinical features, treatment, and follow-up information were analyzed.In this study, diffuse large B-cell lymphoma (DLBCL) (108, 65.5%) and mucosa-associated lymphoid tissue (MALT) lymphoma (52, 31.5%) were two predominant histological subtypes. One-year and 5-year overall survival (OS) rates of all patients were 95.2% and 79.5%, respectively; in whom 110 (66.7%) underwent surgery, 110 (66.7%) received chemotherapy, 12 (7.3%) received radiotherapy, and 10 (6.1%) received Helicobacter pylori eradication. And 75 patients (45.5%) were treated with at least 2 different types of therapies. Elevated lactic dehydrogenase (LDH) levels, poor performance status (PS), advanced stage, International Prognostic Index (IPI) score ≥3, conservative treatment, and high-grade histological subtype were associated with worse prognosis in univariate analysis. Cox regression analysis showed that LDH levels, PS, staging, and histological subtype were independent predictors of survival outcomes. In the DLBCL type, 5-year OS was significantly better in the surgically treated group (80.1%) than that of patients conservatively treated (49.8%) (P = 0.001). Surgical treatment had almost no impact on OS in the MALT type than conservative treatment (P = 0.597). The proportion of patients received conservative treatment increased from 4.5% in period 1 to 51.7% in period 4.High LDH levels, poor PS, advanced staging, and malignant pathological type at diagnosis are significantly associated with poor OS. Our data suggest that surgery is superior in prognosis over conservative treatment in the DLBCL type, but not in the MALT type. Recently, conservative treatment is becoming more preferred approach in patients with PGL.

Abstract
The compass-type anisotropy appears naturally in diverse physical contexts with strong spin-orbit coupling (SOC) such as transition metal oxides and cold atomic gases etc, and it has been receiving substantial attention. Motivated by recent studies and particularly recent experimental observations on helimagnet MnGe, we investigate the critical roles of this compass-type anisotropy in modulating various spin textures of chiral magnets with strong SOC, by Monte Carlo simulations based on a classical Heisenberg spin model with Dzyaloshinsky-Moriya interaction and compass anisotropy. A phase diagram with emergent spin orders in the space of compass anisotropy and out-of-plane magnetic field is presented. In this phase diagram, we propose that a hybrid super-crystal structure consisting of alternating half-skyrmion and half-anti-skyrmion is the possible zero-field ground state of MnGe. The simulated evolution of the spin structure driven by magnetic field is in good accordance with experimental observations on MnGe. Therefore, this Heisenberg spin model successfully captures the main physics responsible for the magnetic structures in MnGe, and the present work may also be instructive to research on the magnetic states in other systems with strong SOC.

Abstract
OBJECTIVE To investigate the impairment in primary cultured rat choroid plexus epithelial cells (CPECs)induced by aluminum. METHODS The choroid plexus isolated from Sprague-Dawley rats 14 days old was cut into pieces and digested by trypsin in the sterile area. The obtained single cells were cultured in DMEM with 1% epidermal growth factor and 20% fetal calf serum. Five days later, immunohistochemistry with anti-transthyretin antibody was used to identify the purity of cultured cells. The well-grown cells were treated with aluminum lactate at different concentrations (0, 100, 400, and 1 600 μmol/L for control, lowdose, mediumdose, and highdose groups). Fortyeight hours later, the cell viability, apoptotic rate, level of reactive oxygen species (ROS), and activity of superoxide dismutase (SOD)were measured in each group to evaluate the impairment in primary cultured rat CPECs by aluminum. RESULTS More than 95% of the cultured cells were identified as CPECs. The medium-and high-dose groups had significantly lower cell viability than the control group(86.74%±4.03% vs 100%, P<0.01; 81.90%±9.17% vs 100%, P<0.01). The high-dose group had significantly lower cell viability than the lowdose group (81.90%±9.17% vs 92.92%±8.81%, P<0.01). The medium-and high-dose groups had significantly higher apoptotic rates than the control group (7.26%±0.99% vs 1.29%±0.03%, P<0.01; 22.25%±1.55% vs 1.29%±0.03%, P<0.01)and the low-dose group (7.26%±0.99% vs 1.68%±0.27%, P<0.01; 22.25%±1.55% vs 1.68%±0.27%, P<0.01). The high-dose group had a significantly higher apoptotic rate than the medium-dose group (22.25%±1.55% vs 7.26%±0.99%, P<0.01). The mediumand high-dose groups had significantly higher fluorescence intensity of ROS than the control group (22.23%±0.41% vs 17.24%±0.09%, P<0.05; 25.10%±1.13% vs 17.24%±0.09%, P<0.05)and the lowdose group (22.23%±0.41% vs 18.31%±0.21%, P<0.05; 25.10%±1.13% vs 18.31%±0.21%, P<0.05). The highdose group had significantly higher fluorescence intensity of ROS than the mediumdose group (25.10%±1.13% vs 22.23%±0.41%, P< 0.05). The low-, medium-and high-dose groups had significantly lower SOD activity than the control group[(28.65±0.74)U/g Hb vs (37.35±1.05)U/g Hb, P<0.05; (22.75±1.94)U/g Hb vs (37.35±1.05)U/g Hb, P<0.05; (13.29±0.64)U/g Hb vs(37.35±1.05)U/g Hb, P<0.05]. The medium-and high-dose groups had significantly lower SOD activity than the low-dose group[(22.75±1.94)U/g Hb vs(28.65±0.74)U/g Hb, P<0.05; (13.29±0.64)U/g Hb vs (28.65±0.74)U/g Hb, P<0.05], while the high-dose group had had significantly lower SOD activity than the medium-dose group[(13.29±0.64)U/g Hb vs (22.75±1.94)U/g Hb, P<0.05]. There were no significant differences in cell viability, apoptotic rate, level of ROS, or activity of SOD between any other two groups (P>0.05). CONCLUSION Aluminum lactate may induce impairment in primary cultured rat CPECs. It reduces the cell viability, elevates the apoptotic rate, and causes oxidative stress.

Abstract
OBJECTIVE To investigate the effects of aluminum lactate exposure on learning and memory and the transportation of amyloid-beta peptides(Aβ) in cerebrospinal fluid in rats. METHODS A total of 80 male Sprague-Dawley rats were randomly divided into solvent control(distilled water) group and low-, medium-, and high-dose aluminum poisoning groups(10, 30, and 90 mg/kg aluminum lactate), with 20 rats in each group, and the poisoning procedure was performed by gavage for 2 months. The Morris water maze test was used to test the rats' learning and memory, Western blot was used to measure the expression level of low-density lipoprotein receptor protein-1(LRP-1) in rats' choroid plexus, and enzyme-linked immunosorbent assay(ELISA) was used to measure the content of Aβ in the cerebrospinal fluid and plasma. RESULTS The Morris water maze test showed that in the place navigation test, with the increasing training time, the escape latency was significantly shortened in each group and showed significant differences between any two groups(P<0.05). In the spatial probe test, the time spent in target quadrant in the medium-and high-dose groups was 11.52±1.56 s and 10.43±5.27 s, respectively, which was significantly shorter than that in the control group and the low-dose group(15.81±3.01 s and 13.91±2.17 s)(P<0.05). The numbers of platform crossings in the medium-and high-dose groups were 2.64±1.39 and 1.50±0.76, respectively, which were significantly lower than those in the control group and the low-dose group(4.29±0.914 and 3.56±1.38)(P<0.05). The results of ELISA showed that the medium-and high-dose groups had significant increases in the content of Aβ1-42 in cerebrospinal fluid(320.35±84.82 pg/ml and 327.68±67.51 pg/ml), which was significantly higher than that in the control group(203.46±74.36 pg/ml) (P<0.05). The content of Aβ1-42 in plasma showed no significant difference between any two groups(P>0.05), and that of Aβ1-40 in cerebrospinal fluid and plasma also showed no significant difference between any two groups(P>0.05). The results of Western blot showed that the high-dose group had significantly lower protein expression of LRP-1 than the control group and the low-and medium-dose groups(0.57±0.21 vs 1.00±0.00/0.79±0.15/0.95±0.24, P<0.05). CONCLUSION Subchronic aluminum exposure may reduce learning and memory in rats, and the accumulation of Aβ in cerebrospinal fluid may be related to the reduced protein expression of LRP-1 in the choroid plexus, suggesting that aluminum affects learning and memory in rats through reducing the protein expression of LRP-1, influencing the transportation of Aβ, and leading to the accumulation of Aβ.

Abstract
The clinical prognostic significance of tumor size (Ts) in gastric cancer remains under debate. This study aims to evaluate the prognostic value of Ts in gastric cancer patients undergoing gastrectomy. A total of 2405 patients with gastric cancer, all having received radical resection, were enrolled in this retrospective study from 2000 to 2011. Patients were categorized by minimum P value from log-rank χ2 statistics using X-tile. The relationships between Ts and other clinicopathologic characteristics were analyzed, and the survival prediction accuracy was also compared between Ts and T stage. Patients were divided into 5 groups, according to which Ts stage and TsNM stage system were proposed. Ts, an independent prognostic factor identified by univariate and multivariate survival analysis, was significantly associated with sex, age, tumor location, macroscopic type, tumor diffferentiation, vessel invasion, perineural invasion, T stage, N stage, and TNM stage. Compared with T stage system, Ts stage system was found no superiorities in survival prediction. However, for patients with lymph node metastasis and patients with age ≥60, Ts stage system revealed a significant improvement of predictive accuracy in subgroup survival analysis. Furthermore, TsNM stage (c-index = 0.783) system was found to be superior to TNM stage (c-index = 0.743) system in prognostic prediction accuracy (P < 0.05). Ts is significantly correlated with gastric cancer progression, which can be regarded as a reliable prognostic factor, and the TsNM stage system may improve the prognostic prediction accuracy in gastric cancer patients.

Abstract
We report the first measurement of the target single-spin asymmetry, A(y), in quasielastic scattering from the inclusive reaction (3)He(↑)(e,e') on a (3)He gas target polarized normal to the lepton scattering plane. Assuming time-reversal invariance, this asymmetry is strictly zero for one-photon exchange. A nonzero A(y) can arise from the interference between the one- and two-photon exchange processes which is sensitive to the details of the substructure of the nucleon. An experiment recently completed at Jefferson Lab yielded asymmetries with high statistical precision at Q(2)=0.13, 0.46, and 0.97 GeV(2). These measurements demonstrate, for the first time, that the (3)He asymmetry is clearly nonzero and negative at the 4σ-9σ level. Using measured proton-to-(3)He cross-section ratios and the effective polarization approximation, neutron asymmetries of -(1-3)% were obtained. The neutron asymmetry at high Q(2) is related to moments of the generalized parton distributions (GPDs). Our measured neutron asymmetry at Q(2)=0.97 GeV(2) agrees well with a prediction based on two-photon exchange using a GPD model and thus provides a new, independent constraint on these distributions.

Abstract
This study aimed to investigate the impact of body mass index (BMI) on the short-term and long-term results of a large cohort of gastric cancer (GC) patients undergoing gastrectomy.Recently, the "obesity paradox" has been proposed, referring to the paradoxically "better" outcomes of overweight and obese patients compared with nonoverweight patients. The associations between BMI and surgical outcomes among patients with GC remain controversial.A single-institution cohort of 1249 GC patients undergoing gastrectomy between 2000 and 2010 were categorized to low-BMI (<18.49 kg/m), normal-BMI (18.50-24.99 kg/m), and high-BMI (≥25.00 kg/m) groups. The postoperative complications were classified according to the Clavien-Dindo system, and their severity was assessed by using the Comprehensive Complication Index (CCI). The impact of BMI on the postoperative complications and overall survival was analyzed.There were 908, 158, and 182 patients in the normal-BMI, low-BMI, and high-BMI groups, respectively. The overall morbidity in the high-BMI group (24.7%) was higher than that in either the low-BMI or the normal-BMI group (20.9% and 15.5%, respectively; P = 0.006), but the mean CCI in the low-BMI group was significantly higher (8.32 ± 19.97) than the mean CCI in the normal-BMI and high-BMI groups (3.76 ± 11.98 and 5.58 ± 13.07, respectively; P < 0.001). The Kaplan-Meier curve and the log-rank test demonstrated that the low-BMI group exhibited the worst survival outcomes compared with the normal-BMI group, whereas the high-BMI group exhibited the best survival outcomes (P < 0.001). In multivariate analysis, BMI was identified as an independent prognostic factor. In the stage-specific subgroup analysis, a low BMI was associated with poorer survival in the cases of stage III-IV diseases.Low BMI was associated with more severe postoperative complications and poorer prognosis. Despite a higher risk of mild postoperative complications, the high-BMI patients exhibited paradoxically "superior" survival outcomes compared with the normal-BMI patients. These findings confirm the "obesity paradox" in GC patients undergoing gastrectomy.

Abstract
Anthropogenic activities have seriously impacted wild resources of the Amur sturgeon, Acipenser schrenckii, and more information on local and regional population genetic structure is required to aid the conservation of this species. In this study, we report the development of 12 novel polymorphic microsatellite loci using next-generation sequencing technology, and the genotyping of 24 individuals collected from a sturgeon farm. The results show that the mean number of ob-served alleles per locus is 6.6 (ranging from 2 to 17). Observed and expected heterozygosity values ranged from 0 to 0.958 and from 0.508 to 0.940, respectively. Not a single locus showed significant departure from Hardy-Weinberg equilibrium and no linkage disequilibrium was observed among any pairwise loci. These highly informative microsatellite markers will be useful for genetic diversity and population structure analyses of A. schrenckii and other species of this genus.

Abstract
BACKGROUND/AIMS Facing with the high incidence rate and the poor outcomes of the postoperative pulmonary complications (PPCs), we sought to evaluate potential risk factors for developing the PPCs of gastric cancer patients. METHODOLOGY Retrospective study was carried out to analyze consecutive gastric cancer patients who had a preoperative pulmonary function test and underwent gastrectomy in the West China Hospital (January, 2000 - December, 2009). Potential risk factors to the development of the PPCs and the survival outcomes of these patients were also analyzed. RESULTS Totally, one hundred and twenty four patients (18.1%) were developed the PPCs after gastrectomy. For the development of the PPCs, univariate analysis identified the following risk factors is associated with the development of the PPCs: age ≥ 70 years (p < 0.001); male patients (p = 0.041); FEV1/FVC < 60 (p < 0.001); with the history of pulmonary disease (p < 0.001); hemoglobin < 90g/L (p = 0.025); serum albumin < 35g/L (p = 0.002); combined organoectomy (p = 0.036). Multivariate analysis identified FEV1/FVC < 60 (p = 0.004); with the history of pulmonary disease (p < 0.002); serum albumin < 35g/L (p = 0.004) were risk factors for the incidence of the PPCs. CONCLUSIONS For the early detection of the PPCs, extra attention should be paid to those gastric cancer patients with FEV1/FVC < 60; history of pulmonary disease and .serum albumin < 35g/L.

Abstract
BACKGROUND Gemtuzumab ozogamicin (GO) is a targeted antineoplastic agent comprised of a recombinant anti-CD33 humanized antibody linked to calicheamicin. Previous trials have showed conflicting results concerning the efficacy and toxicity of adding GO to induction chemotherapy for newly diagnosed acute myeloid leukemia (AML). A systematic review and meta-analysis was conducted to resolve this controversial issue. PATIENTS AND METHODS Summary data from five randomized phase III trials compared adding GO to induction chemotherapy with induction chemotherapy alone for newly diagnosed AML were meta-analyzed. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) for overall survival (OS) and relapse-free survival (RFS), and pooled odds ratios (ORs) and 95% CIs for complete remission (CR) rate, incidences of resistance disease, relapse and toxicity were calculated. RESULTS Data of 3596 patients (1798 GO and 1798 controls) from five randomized phase III trials were analyzed. Compared with induction chemotherapy alone, adding GO significantly prolonged OS (HR 0.93, 95% CI 0.86-1.00, P=0.05) and RFS (HR 0.87, 95% CI 0.79-0.95, P=0.003), decreased the incidences of resistant disease (OR 0.71, 95% CI 0.55-0.93, P=0.01) and relapse (OR 0.75, 95% CI 0.63-0.90, P=0.002), but had no effect on CR rate (OR 1.15, 95% CI 0.91-1.46, P=0.24). Sensitivity analysis yielded similar results. Subgroup analysis identified that cytogenetics might be an influencing factor for the effect of adding GO. In addition, the risks of grade 3-4 nausea/vomiting, diarrhea and liver aspartate transaminase (AST) elevation were increased in GO arm. CONCLUSIONS Adding GO to induction chemotherapy for newly diagnosed AML can significantly prolong OS and RFS, decrease incidences of resistant disease and relapse, but may increase risks of grade 3-4 nausea/vomiting, diarrhea and liver AST elevation.
