Abstract
Objective: To compare the prognostic value of 3 diagnostic criteria of bronchopulmonary dysplasia (BPD) in preterm infants with gestational age<32 weeks. Methods: The retrospective cohort study was conducted to collect the clinical data of 285 preterm infants with BPD admitted to the Department of Neonatology, Children's Hospital Affiliated to Zhengzhou University from January 2019 to September 2021, who were followed up regularly after discharge. The primary composite adverse outcome was defined as death or severe respiratory morbidity from 36 weeks of corrected gestational age to 18 months of corrected age, and the secondary composite adverse outcome was defined as death or neurodevelopmental impairment. According to the primary or secondary composite adverse outcomes, the preterm infants were divided into the adverse prognosis group and the non-adverse prognosis group. The 2001 National Institute of Child Health and Human Development (NICHD) criteria, 2018 NICHD criteria, and 2019 Neonatal Research Network (NRN) criteria were used to diagnose and grade BPD in preterm infants. Chi-square test, Logistic regression analysis, receiver operating characteristic (ROC) curve and Delong test were used to analyze the prognostic value of the 3 diagnostic criteria. Results: The 285 preterm infants had a gestational age of 29.4 (28.1, 30.6) weeks and birth weight of 1 230 (1 000, 1 465) g, including 167 males (58.6%). Among 285 premature infants who completed follow-up, the primary composite adverse outcome occurred in 124 preterm infants (43.5%), and the secondary composite adverse outcome occurred in 40 preterm infants (14.0%). Multivariate Logistic regression analysis showed that severe BPD according to the 2001 NICHD criteria, gradeⅡand Ⅲ BPD according to the 2018 NICHD criteria and grade 2 and 3 BPD according to the 2019 NRN criteria were all risk factors for primary composite adverse outcomes (all P<0.05). ROC curve showed that the area under the curve (AUC) of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.70 and 0.70 vs. 0.61, Z=4.49 and 3.35, both P<0.001), but there was no significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.38, P=0.702). Multivariate Logistic regression analysis showed that the secondary composite adverse outcomes were all associated with grade Ⅲ BPD according to the 2018 NICHD criteria and grade 3 BPD according to the 2019 NRN criteria (both P<0.05). ROC curve showed that the AUC of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.71 and 0.71 vs. 0.58, Z=2.93 and 3.67, both P<0.001), but there was no statistically significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.02, P=0.984). Conclusion: The 2018 NICHD and 2019 NRN criteria demonstrate good and comparable predictive value for the primary and secondary composite adverse outcomes in preterm infants with BPD, surpassing the predictive efficacy of the 2001 NICHD criteria.

Abstract
The current treatment strategy for rectal cancer is a comprehensive treatment centered on surgery. The application of total mesorectal excision (TME) has significantly reduced the local recurrence rate and improved the survival prognosis, but a series of pelvic organ dysfunction caused by pelvic autonomic nerve injury during the operation will reduce the postoperative quality of life of patients. Pelvic autonomic nerve preserving (PANP) radical proctectomy has emerged, but the biggest challenge in the implementation process of this technology is the accurate identification of nerves. A series of studies have shown that pelvic intraoperative autonomic monitoring (pIONM) can effectively assist surgeons to identify nerves, The purpose of this article is to introduce the function of pelvic autonomic nerve, the clinical manifestation of postoperative pelvic dysfunction and its relationship with nerve injury, the key points of implementing PANP, and the current situation and research progress of pIONM technology application.

Abstract
Objective: To analyze the burden and changing trends of periodontal disease in adults of the mainland of China from 1990 to 2019, and to predict the incidence trends of periodontal disease in the next 25 years, with a goal to provide a basis for reducing the burden of periodontal disease and formulating relevant prevention and treatment measures. Methods: Data on the incidence, prevalence, and disability adjusted life years (DALY) rate of periodontal disease among adults in the mainland of China from 1990 to 2019 were extracted from the global burden of disease study 2019 (GBD 2019) database. The estimated annual percent change (EAPC) was used to estimate the temporal trend of periodontal disease, and the age-period-cohort model (APC) was used to predict the age-standardized incidence of periodontal disease in Chinese adults from 2020 to 2044. Results: From 1990 to 2019, the incidence, prevalence, and DALY rate of adult periodontal disease in the mainland of China showed an increasing trend, with EAPCs of 0.3 (95%CI: 0.1-0.6), 0.5 (95%CI: 0.1-0.8), and 0.5 (95%CI: 0.1-0.8), respectively. The incidence and prevalence of periodontitis among the population aged 35-39 years old and 40-44 years old increased the most significantly, with EAPCs of 0.8 and 0.7, respectively, whereas the change in periodontal disease prevalence tended to be stable and the increase trend in prevalence was lower in the elderly group (EAPC=0.4). The incidence (EAPC=2.1), prevalence (EAPC=2.6) and DALY rate (EAPC=2.6) of periodontal disease in females increased more than those in males (EAPC=1.9, 2.4, and 2.4, respectively), of which the prevalence had exceeded that of males in 2019. The APC model predicted that the prevalence of periodontal disease in the period of 2020-2044 in China would still be on an upward trend, and the increase rate would be higher in females than in males. Conclusions: The burden of periodontal disease among adults in China had been increasing over the past 30 years, especially among young and middle-aged adults as well as females, and the incidence of periodontal disease will continue to increase over the next 25 years.

Abstract
AIM To evaluate the overall diagnostic performance of magnetic resonance imaging (MRI), different image features, and different image analysis methods in predicting hepatocellular carcinoma (HCC) with cytokeratin 19 (CK19) expression. MATERIALS AND METHODS A systematic literature search was performed to identify studies using MRI to predict HCC with CK19 expression between 2012 and 2023. Data were extracted to calculate the pooled sensitivity and specificity. Overall diagnostic performance was assessed using areas under the summary receiver operating characteristic curve (AUC). Subgroup analyses were conducted for specific image features and according to image analysis methods (traditional image feature, radiomics, and combined methods). Z-test statistics was used to analyse the differences in diagnostic performance between combined and individual methods. RESULTS Eleven studies with 14 datasets (1,278 lesions from 1,264 patients) were included. The overall pooled sensitivity, specificity, and AUC with corresponding 95% confidence intervals were estimated to be 0.72 (0.55, 0.85), 0.88 (0.80, 0.93), and 0.89 (0.86, 0.91) for MRI in predicting HCC with CK19 expression. Combined methods had higher sensitivity than image feature methods (0.86 versus 0.54, p=0.001), with no difference in specificity (0.85 versus 0.87, p=0.641). There were no significant differences between radiomics and combined methods regarding sensitivity (p=0.796) and specificity (p=0.535), respectively. CONCLUSION MRI shows moderate sensitivity and high specificity in identifying HCC with CK19 expression. The application of radiomics can improve the sensitivity of MRI in identifying HCC with CK19 expression.

Abstract
Cadmium (Cd) is a common contaminant in aquatic environments. However, little is known about the mechanisms underlying Cd toxicity in the freshwater snail Cipangopaludina cathayensis (Heude, 1890). This study to investigate the toxic effects of Cd on the standard metabolism, antioxidant activities, immune function, and hepatopancreas transcriptome profiles of C. cathayensis. C. cathayensis was exposed to 0.25, 0.5, 1.0, or 1.5 mg/L Cd for 3 h, with results showing that Cd significantly inhibited oxygen consumption and ammonia excretion and disrupted the respiratory metabolism of C. cathayensis. In addition, the O:N ratio dropped below 7, indicating that C. cathayensis may rely exclusively on proteins as an energy source under Cd stress. To understand how Cd impacts the antioxidant activities, immune function, and transcriptional profiles, C. cathayensis were exposed to 0.5 (low exposure, L14) or 1.5 (high exposure, H14) mg/L Cd for 14 days. Our results indicate that Cd exposure leads to oxidative stress and immunosuppression, with the latter effect being larger for exposure to higher Cd concentrations. A total of 2172 differentially expressed genes (DEGs) were identified by transcriptome analysis of the hepatopancreas, of which 885 were upregulated and 1287 were downregulated. Gene ontology and KEGG analyses revealed that the DEGs in the H14 group are enriched for energy generation terms and the "oxidative phosphorylation" pathway, respectively. Therefore, up-regulation of energy metabolism may be an adaptive strategy under Cd stress. Moreover, several genes involved in antioxidant activity were downregulated, whereas genes related to reactive oxygen species generation were upregulated. In addition, many immunity-related genes were identified within the DEGs, indicating that Cd toxicity may affect immune defense. Further, DEGs in the H14 group were enriched for disease-associated pathways. Taken together, our results indicate that Cd exposure leads to metabolic disorders, oxidative stress, and immunosuppression and thus may potentially contribute to disease outbreaks.

Abstract
To analyze the association between exposure to air pollution and respiratory disease of primary school students in Chongqing City. Eight districts and counties were randomly selected based on the air pollution situation in Chongqing City. In each selected district and county, one primary school was randomly selected. A questionnaire survey was conducted on all primary school students in Grades 3-5 by the end of 2019. Air quality data from the nearest environmental monitoring sites were collected. A logistic regression model was used to analyze the impact of the living environment, lifestyle and air pollution on the respiratory disease of surveyed students. This study included 5 918 primary school students, with a prevalence rate of respiratory disease of 21.54%. The prevalence rates of boys and girls were 23.38% and 19.59%, respectively. The average Air quality index (AQI) of the surveyed school was 67, and the rates of exceeding standards of PM10, PM2.5, NO2 and O3 were 1.16%, 6.92%, 0.99% and 5.65%, respectively. The level of SO2 and CO did not exceed the standard. After adjusting for relevant factors, logistic regression analysis showed that primary school students in areas with high exposure to air pollution (OR=2.52), using air pollution related-chemicals at home (OR=1.47), passive smoking (OR=1.27), and keeping pets at home (OR=1.18) had a higher risk of respiratory disease (all P<0.05). In addition, the average annual values of AQI (OR=1.18), PM10 (OR=1.20), PM2.5 (OR=1.35), and NO2 (OR=1.11) increased the risk of respiratory diseases in primary school students (all P<0.05). In conclusion, the respiratory disease of primary school students in Chongqing City is related to the living environment, behavior habits and ambient air quality. The increased exposure concentration of PM10, PM2.5 and NO2 in air pollutants can lead to an increased risk of respiratory disease among primary school students.

Abstract
Objective: To investigate the relationship between the long-non-coding RNA LINC00342 expression and the clinicopathological parameters of head and neck squamous cell carcinoma (HNSCC) and the biological function of LINC00342 in HNSCC cells. Methods: The expression level of LINC00342 in the HNSCC was analyzed using transcriptome sequencing data from TCGA (The Cancer Genome Atlas) database, and the expressions of LINC00342 in laryngeal squamous cell carcinoma tissues (LSCC) of 27 patients in the First Hospital of Shanxi Medical University were detected by transcriptome sequencing. The expression levels of LINC00342 in human embryonic lung diploid cells 2BS, HNSCC cell lines FD-LSC-1, CAL-27 and Detroit562 were determined by real-time quantitative polymerase chain reaction (qPCR). RNAi (RNA interference) was used for LINC00342 knockdown in HNSCC cell lines, and the changes of malignant phenotype in the tumor cells after LINC00342 knockdown were examined by cell counting kit-8 (CCK-8), colony formation, flow cytometry, transwell invasion and migration assays. Bioinformatics analysis was performed to construct a LINC00342-centered competing endogenous RNA (ceRNA) regulatory network, and GO (Gene Ontology) enrichment analysis was performed. Statistical analysis and graphing were performed using SPSS 25.0 software and GraphPad Prism 6 software. Results: Mean LINC00342 levels in HNSCC tissues and TCGA database were higher than that in normal control tissues, but with no significantly statistical difference (P=0.522). LINC00342 expression levels were positively correlated with cervical lymph node metastasis and pathological grade in patients with HNSCC, with higher expression in male patients than in female patients (P<0.05). Transcriptome sequencing analysis showed that mean expression level of LINC00342 in LSCC tissues of 27 patients was significantly higher than that in the paired adjacent normal mucosa tissues (t=1.56, P=0.036). LINC00342 expression was significantly upregulated in HNSCC cell lines FD-LSC-1, CAL-27 and Detroit562 (t-values of -12.17, -23.26 and -388.57, respectively; all P<0.001). Knockdown of LINC00342 by transfecting si-LINC00342-1 and si-LINC00342-2 inhibited HNSCC cell proliferation (t-values of 8.95 and 4.84, 2.70 and 5.55, 2.02 and 3.70, respectively), colony formation (t-values of 6.66 and 6.17, 7.38 and 11.65, 4.90 and 5.79, respectively), migration (t-values of 8.21 and 7.19, 5.76 and 6.46, 6.28 and 9.92, respectively) and invasion abilities (t-values of 9.29 and 10.25, 11.30 and 11.36, 8.02 and 8.66, respectively), but promoting apoptosis in cell lines FD-LSC-1 and CAL-27 (t-values of -2.21 and -5.83, -3.05 and -5.25 respectively) (all P-values<0.05). The LINC00342-centered ceRNA network consists of 10 downregulated microRNA and 647 upregulated mRNA nodes. GO analysis results indicated that LINC00342-regulated mRNAs were enriched in 22 biological processes, 32 molecular functions, and 12 cellular components. Conclusion: High level of LINC00342 is associated with the malignant progression of HNSCC. LINC00342 promotes the proliferation, migration, invasion, and antagonizes apoptosis of HNSCC cells, which serves as a potential molecular marker in HNSCC.

Abstract
Objective: To investigate the prevalence and risk factors of medication non-adherence in children with inflammatory bowel disease (IBD). Methods: A cross-sectional study was conducted in Children's Hospital, Zhejiang University School of Medicine from September 2020 to March 2022 and 112 children with IBD were enrolled. Their general information, medication adherence, and parental disease-related knowledge were collected by questionnaires. According to the medication adherence score, the children were divided into the adherence group (score of 6 to 8) and the non-adherence group (score of <6), then the demographic and clinical characteristics of the two groups were compared. Subsequently, a multivariate binary Logistic regression analysis was performed to determine the risk factors of medication non-adherence. Results: Of the 112 children, 76 were males and 36 females, with the age of 12.9 (9.5, 14.0) years. There were 50 (44.6%) in the non-adherence group and 62 (55.4%) in the adherence group. Regarding the demographic and clinical characteristics, the results showed that the dosage frequency and the parental disease related knowledge were associated with medication non-adherence (both P<0.05). Multivariate binary Logistic regression analysis showed that compared with 0-6 years old children, the risk of medication non-adherence was significantly increased in children aged 7-12 years (OR=9.30, 95%CI 1.58-54.87, P=0.014) and 13-18 years (OR=8.26, 95%CI 1.49-45.85, P=0.016); and the risk was also significantly increased in children who took medication twice or more per day (OR=12.88, 95%CI 2.77-59.80, P=0.001) compared with children who took medication once per day. Meanwhile, the parental score of the questionnaire on Crohn's disease and ulcerative colitis related knowledge (OR=0.76, 95%CI 0.66-0.89, P=0.001) was also a significant risk factor. Conclusions: Medication non-adherence is common in children with IBD. Children older than 7 years, a dosage frequency of twice or more per day, and parental poor disease-related knowledge are the independent risk factors for medication non-adherence in children with IBD. Clinicians should pay attention to promoting patients' adherence to improve clinical outcomes.

Abstract
Aberrant activation of EGFR due to overexpression or mutation is associated with poor prognosis in many types of tumors. Here we show that blocking the sorting system that directs EGFR to plasma membrane is a potent strategy to treat EGFR-dependent tumors. We find that EGFR palmitoylation by DHHC13 is critical for its plasma membrane localization and identify ARF6 as a key factor in this process. N-myristoylated ARF6 recognizes palmitoylated EGFR via lipid-lipid interaction, recruits the exocyst complex to promote EGFR budding from Golgi, and facilitates EGFR transporting to plasma membrane in a GTP-bound form. To evaluate the therapeutic potential of this sorting system, we design a cell-permeable peptide, N-myristoylated GKVL-TAT, and find it effectively disrupts plasma membrane localization of EGFR and significantly inhibits progression of EGFR-dependent tumors. Our findings shed lights on the underlying mechanism of how palmitoylation directs protein sorting and provide an potential strategy to manage EGFR-dependent tumors. EGFR is aberrantly activated in many cancer types. Here the authors show that small GTPase ARF6 mediates the trafficking of palmitoylated EGFR from Golgi to plasma membrane and the blockade of this sorting system inhibits the growth of EGFR overexpression tumours.

Abstract
Objective: To investigate the epidemiological characteristics of COVID-19 caused by 2019-nCoV Delta variant in Shangyu district, Shaoxing of Zhejiang province in 2021, and provide evidence for the improvement of COVID-19 control and prevention measures. Methods: The incidence data of COVID-19 in Shangyu from December 7 to 21, 2021 was obtained from Shangyu District Center for Disease Control and Prevention. The epidemiological characteristics of the cases, i.e. the population, time and space distributions, were analyzed, and the incubation period and time-varying reproduction numbers (Rt) were calculated. Results: From December 7 to 21, 2021, a total of 380 COVID-19 cases caused by 2019-nCoV Delta variant were detected in Shangyu, the median age of the cases was 52 years, M (Q1,Q3: 38, 61). The male to female ratio of the cases was 1∶1.25, and the cases were mainly workers (36.58%) and farmers (27.63%). The epidemic affected 9 townships (or community) of Shangyu, especially Caoe and Baiguan communities with the cases accounting for 57.10% and 31.53% respectively. The median incubation period of cases was 4.00 days, M (Q1,Q3: 3.00, 5.75). The basic reproduction number (R0) was 4.06, and the Rt was 5.62 in early phase of the outbreak (the highest) and continuously decreased to less than 1.00 within 10 days after the detection of the outbreak. The number of COVID-19 cases decreased to 0 within 14 days after the outbreak (December 7-21), and the main detection methods were screening in centralized isolation (55.53%) and home isolation (40.00%). The infection rates of close contacts and secondary close contacts were 2.06% and 0.46% respectively. Conclusion: The epidemic of COVID-19 in Shangyu characterized by short incubation period, large number of infected people, and case clustering, suggesting the strong transmission of Delta variant (B.1.617.2). Comprehensive prevention and control measures, such as management of close contacts and secondary close contacts, and high-risk area, are essential for the rapid control of the epidemic.

Abstract
Objective: To explore the role of nonalcoholic fatty liver disease (NAFLD) in the development of hepatocellular carcinoma (HCC) in patients with prior hepatitis B virus infection (HBsAg-negative and anti-HBC-positive). Methods: 1605 hospitalized patients who were first diagnosed with HCC at Nanfang Hospital between 2015 to 2017 were retrospectively studied. Patients who developed HCC on the basis of active HBV infection (HBsAg-positive, anti-HBc positive) were used as control. Multivariate logistic regression model was used to analyze the relationship between NAFLD and HCC in patients with prior hepatitis B virus infection. Results: Among HCC patients with both HBsAg and anti-HCV negative, the proportion of prior HBV infection accounted for 86.7%. NAFLD prevalence was higher in patients with HCC based on prior HBV infection than active HBV infection (19.7% vs. 8.5%, P < 0.001). After adjusting for gender, age, hypertension, alanine aminotransferase, and liver cirrhosis, patients with HCC based on prior HBV infection were more likely to develop NAFLD (OR: 2.29, 95% CI: 1.40-3.74), and this phenomenon was observed only in patients with non-cirrhosis (OR: 5.26, 95% CI: 2.53-10.96) and aged≥50 years (OR: 2.36, 95% CI: 1.33-4.20). Conclusion: NAFLD may be a risk factor for HCC in a previously infected patients with HBV, especially in non-cirrhotic and population aged≥50 years.

Abstract
With the accelerating globalization and the implementation of "Belt and Road" initiative proposed by our government, communication and exchanges between China and foreign countries have become more and more frequent than before, and much more international students have chosen to study in China's universities as candidates of master of public health (MPH). However, because China only launched the MPH program in recent years, with the training models being highly similar to the program of master of science in China but quite different from those of main international MPH programs, hindering China's MPH program to become an international one. This paper systematically evaluated existing training models of MPH programs both at home and abroad through literature review and identified major differences and deficiencies of China's MPH program compared to those from other countries: (1) requirement for medical background only; (2) comparatively longer period to complete the program; (3) incomplete curriculum; (4) overemphasizing scientific research competencies but somewhat neglecting practical abilities; and (5) limited career choices, and put forward some suggestions to improve the MPH program of China, including removing requirement for medical background only, shortening the period of MPH program, improving the curriculum of MPH program, and enhancing the training of practical abilities.

Abstract
Objective: To investigate the proportion of hepatitis B-related hepatocellular carcinoma (HCC) patients who have received antiviral therapy and compare the clinical characteristics of HCC patients who have received antiviral therapy with those who have not received antiviral therapy. Methods: Data of 2590 newly diagnosed hepatitis B-related HCC cases who were hospitalized in Nanfang Hospital from 2015 to 2017 were collected. Two independent sample t-tests, Mann-Whitney U test, and χ(2) test were used to compare the clinical characteristics of hepatitis B-related HCC patients who had received antiviral therapy and those who had not received antiviral therapy. Propensity score was used to match some clinical characteristics of the two groups of patients, and the differences in clinical characteristics of the two groups of patients after matching were further compared. Patients with HCC who had not received antiviral therapy were used as reference, and then the clinical characteristics of HCC patients who had received antiviral treatment were analyzed using multivariate logistic regression. Results: Among the 2 590 patients with hepatitis B-related HCC, only 18.10% of patients had received antiviral therapy, while 82.20% of patients who did not receive antiviral therapy met the treatment criteria. HCC patients who had received antiviral therapy were older (P < 0.05), had a higher proportion of liver cirrhosis (P < 0.001), and lower levels of platelets and alanine aminotransferases and smaller maximum tumor diameter (P < 0.001). In terms of metabolic disease, patients who had received antiviral treatment had higher prevalence of diabetes (14.50% vs. 7.70%, P < 0.001), hypertension (16.60% vs. 11.20%, P < 0.05), obesity (28.50% vs. 22.30%, P < 0.05), overweight (53.80% vs. 43.50%, P < 0.001) and non-alcoholic fatty liver disease (18.30% vs.8.00%, P < 0.001). After matching other different clinical characteristics, the prevalence of diabetes, hypertension, and non-alcoholic fatty liver disease in patients who received antiviral therapy was still higher than that of patients who did not receive antiviral therapy (14.50% vs. 9.80%, P < 0.05; 16.60% vs. 10.20%, P < 0.05; 18.30% vs. 7.00%, P < 0.001). Multivariate logistic regression analysis showed that HCC patients who had received antiviral therapy had a higher risk of developing non-alcoholic fatty liver disease (OR: 2.054, 95% CI: 1.404~3.004) than those who had not received antiviral therapy. Conclusion: Among patients with hepatitis B-related HCC, the proportion of patients who have received antiviral therapy is significantly low (under 20%), which suggests that the popularization and promotion of antiviral therapy has a long way to go. Compared with HCC patients who have not received antiviral therapy, the proportion of HCC patients who have received antiviral therapy combined with metabolic diseases is higher; therefore, it is necessary to pay more attention to the role of metabolic factors in the pathogenesis of hepatitis B-related HCC.

OBJECTIVES This article aims to examine the disparities in dental service utilization among 3 age groups: younger adults (20-49 y), middle-aged adults (50-64 y), and older adults (65+ y), among Whites, Hispanics, Blacks, Asians, American Indians or Alaska Natives (AIAN), and Native Hawaiian or other Pacific Islanders (NHOPI). METHODS Weighted logistic regression models were conducted to analyze 9 waves of cross-sectional survey data (2002-2018) from the Behavioral Risk Factor Surveillance System. We estimated age group- and race/ethnic-specific prevalences of dental service utilization adjusting sociodemographics and self-rated health for each wave and compared with crude analysis. Next, we performed linear regression analysis of the trend of adjusted prevalences over time and the average level by race/ethnicity and age groups. RESULTS Racial/ethnic disparities increased with age, even though the adjusted prevalences of dental service utilization were less apparent than the crude analysis. The all-wave average prevalence was 71%. Black older adults had the lowest level of dental service utilization (65%) as compared with the 2 highest groups: White older adults (79%) and Asian older adults (76%). The general younger adult populations had low prevalences, with the lowest among Asian younger adults (65%). AIAN and NHOPI individuals from all age groups tended to have average or below average prevalences. In addition, a decreasing trend of dental service utilization was observed among White individuals of all age groups (0.2%-0.3% lower per year, P < 0.01) and AIAN younger adults (0.5% lower per year, P < 0.01). CONCLUSION Health policy, federal funding, and community-based programs should address the needs of dental service utilization for racial/ethnic minorities including Blacks, AIANs, and NHOPIs. KNOWLEDGE TRANSFER STATEMENT Our study offers insights into our understanding of disparities in dental service utilization among minority racial/ethnic groups. As health policy, federal funding, and community-based programs seek to improve oral health, there is a need to address access to and utilization of dental service for Blacks, American Indians or Alaska Natives, and Native Hawaiian or other Pacific Islanders.

Abstract
Fibroblast-like synoviocytes (FLSs) exert a critical effect in the occurrence and progress of rheumatoid arthritis (RA). MicroRNA-495 (miR-495) can regulate many growth behaviors in various cell types. Nevertheless, the role of miR-495 is still unclear in RA-FLS. We aimed to explore the role and molecular mechanism of miR-495 in RA. The FLSs and synovial tissue from normal and RA cases were used in the study. RT-PCR analysis was used to examine the expression of miR-495. Western blot assay was conducted to determine the levels of matrix metalloproteinase-9 (MMP-9), matrix metalloproteinase-2 (MMP-2) and β-catenin. Cell counting kit-8 (CCK-8) assays were performed to determine the proliferation of RA-FLS in different treatment groups. The results showed that miR-495 is down-regulated in both RA-synovial tissue and RA-FLSs. Overexpression of miR-495 could inhibit RA-FLS proliferation and inflammatory factors of interleukin (IL)-6, IL-11 and tumor necrosis factor alpha (TNF-α), and decrease the protein expression of MMP-9 and MMP-2. In addition, miR-495 could negatively regulate the expression of β-catenin in RA-FLSs. We also confirmed that the inhibitory role of miR-495 in RA-FLS is through the regulation of β-catenin expression. Taken together, miR-495 is downregulated in RA-FLS and RA synovial tissue, and miR-495 inhibits proliferation and inflammatory response in RA-FLS, partially via regulating β-catenin expression. The miR-495/β-catenin pathway may serve as a new therapeutic target for RA.

Abstract
Objective: To investigate the value of 3.0T MRI diffusion kurtosis imaging (DKI) quantitative histogram parameters in the differential diagnosis of rectal mucinous adenocarcinoma (MC) and common adenocarcinoma (AC). Methods: One hundred and ten patients from Department of Radiology, the Second Affiliated Hospital of Soochow University between September 2015 and September 2019 with complete magnetic resonance imaging (MRI) and DKI results confirmed by surgery and pathology were retrospectively analyzed, including 16 patients in MC group and 94 patients in AC group. Two physicians outlined the region of interest (ROI) on the DKI image with b=1 000 s/mm(2), and obtained quantitative DKI parameters, including the diffusion coefficient (D value) and kurtosis coefficient (K value) corrected for non-Gaussian distribution. The apparent diffusion coefficient (ADC) values of quantitative parameters of diffusion-weighted imaging (DWI) were obtained through image registration, and histogram analysis was performed to obtain the mean value, 25th percentile, 50th percentile, 75th percentile, skewness and kurtosis of the above parameters, respectively. The difference between the quantitative histogram parameter analysis results of the rectal MC group and the AC group was evaluated, and the main indicators and multivariate comprehensive analysis indicators was screened, and the effectiveness of quantitative histogram parameters related to histopathological classification in the differential diagnosis of rectal MC and AC was evaluated. Results: There was no significant differences in gender, age, lesion location, T stage or N stage between MC group and AC group (all P>0.05). The multivariate binary logistic stepwise regression screening showed that D50th percentile and K25th percentile are statistically significant indicators (B values were 2 966.166 and -4.550, respectively; Wals values were 9.000 and 15.720, respectively; and P values were 0.003 and <0.001, respectively). The combined area under the curve of the two indictors was 0.85, but there was no statistically significant difference in pairwise comparison using DeLong method (P>0.05). The results of histogram analysis of quantitative parameters measured by the two physicians were consistent, and the inter-group correlation coefficient ranged from 0.880 to 0.981. Conclusions: The quantitative parameter histogram analysis of the DKI double-index model is helpful for the differentiation of rectal MC and AC, in which the D50th percentile and K25th percentile have differential diagnosis significance, and are superior to the ADC value of the single-index model.

Abstract
Abstract
Background
Genetics plays an important role in the development of type-2 diabetes (T2D). Polygenic risk scores (PRS) are increasingly used to quantify genetic risk of T2D in epidemiological studies. These scores, when integrated into analyses of modifiable lifestyle factors, may improve understanding of T2D etiology, as the strength of association with T2D and some lifestyle or demographic factors may vary according to genetic predisposition.
Methods
We examined PRS-lifestyle factor interactions on T2D with data from the United States Health and Retirement Study (HRS), a prospective longitudinal cohort of older adults (≥50 at baseline). HRS contains nationally representative samples of Black and White Americans with pre-calculated PRS for T2D (N = 14,001). Covariates included sex, education, BMI, smoking, alcohol, and physical activity. Predicted prevalence and incidence of T2D were calculated with logistic regression models. Nonparametric bootstrap method was performed to calculate differences in T2D prevalence and incidence by PRS percentiles and interaction variables.
Results
Significant interaction (p_interaction=0.0096) was detected between PRS and physical activity among Whites only. In those with the lowest decile of PRS, T2D prevalence was similar (∼10%) for those reporting no physical activity compared to low or moderate activity. In those with the top decile of PRS, lower T2D prevalence (17%, 95%CI:14.8,19.6) was observed among those with moderate compared to no activity (24%, 95%CI:20.4,27.5). Incident T2D in Whites followed a similar pattern (p_interaction=0.0194). Among Black participants, no significant interaction with any lifestyle variables was detected.
Conclusions
Interaction of different genetic risk profiles with lifestyle factors may inform understanding of why certain inventions are more or less effective in different groups of people, potentially improving clinical and prevention interventions.
Key messages
Protection conferred by physical activity on T2D varied by underlying genetic risk. Gene-environment interaction studies provide insights on why lifestyle factors vary in their associations with T2D.

Abstract
Objective: To investigate the clinical features and outcome of treatment for novel coronavirus pneumonia. Methods: Literature on novel coronavirus pneumonia was retrieved from PubMed and EMBASE databases. The relevant data was extracted and a meta-analysis was performed using StatsDirect statistical software V.2.8.0 to calculate the combined odds ratio. Results: Seven studies were included, consisting of 1594 cases. The meta-analysis result showed that the most common clinical symptoms of the novel coronavirus pneumonia were fever (91.6%) and cough (64.5%), followed by dyspnea (32.8%) and sputum (28.1%). Headache (10.5%), sore throat (11.2%), hemoptysis (3.2%), diarrhea (6.6%) and the other symptoms were relatively rare. Aspartate aminotransferase (29%), alanine transaminase (22.7%), and total bilirubin (11.7%) levels were elevated, except for serum albumin levels (80.4%). The common therapeutic agents used were antibiotics (87.7%), antiviral drugs (75.5%), and glucocorticoids (26.6%), while antifungal agents (7.7%) were used in few. Mechanical ventilation (13.4%), extracorporeal membrane oxygenation (1.9%), and continuous renal replacement therapy (3.8%) were used in severe cases. The rate of mortality in hospital was 7.7%, respectively. Heterogeneity between studies was significant; however, subgroup and sensitivity analysis had failed to identify clear sources of heterogeneity. Conclusion: Fever, cough and liver dysfunction are the main clinical manifestations of this disease and the mortality rate is low.

Abstract
UNLABELLED Using national insurance claims of Taiwan, we found that magnesium oxide (MgO) use is associated with an increased risk of hip fracture in the elderly. Further studies are warranted to explore the mechanisms associated with MgO use that lead to hip fracture. PURPOSE The purpose of this study was to investigate the association between MgO use and hip fracture risk in the elderly (age > 65 years). METHODS This nationwide population-based retrospective study was conducted from 1996 to 2013. Individuals with (n = 26,069) and without (n = 26,069) MgO use were enrolled after propensity score matching. Primary outcome was a hip fracture. After adjusting for age, sex, comorbidities, and medications, multivariate Cox proportional hazards regression models were used to calculate incidences and risk of hip fracture [hazard ratio (HR)]. RESULTS During the mean follow-up duration of 4.8 years in the MgO cohort and 5.7 years in the non-MgO cohort, respectively 1547 and 1107 cases developed a hip fracture. MgO use was identified as a risk factor for hip fracture in both univariate [crude HR, 1.68; 95% confidence interval (CI), 1.55-1.81; p < 0.001] and multivariate [adjusted HR (aHR), 1.66; 95% CI, 1.54-1.80; p < 0.001] Cox proportional hazards regression models. The cumulative incidence of hip fracture was significantly higher in the MgO cohort than in the non-MgO cohort (1.23 per 100 person-years vs. 0.74 per 100 person-years, logrank test, p < 0.001). CONCLUSION MgO use is an independent risk factor for hip fracture in the elderly.

Abstract
Objective: The authors aim to provide genetic counselling and prenatal gene diagnosis to the families with osteogenesis imperfecta(OI), based on the identification of pathogenetic mutations in large cohort genetic testing. Methods: DNA was extracted from the peripheral blood of parents of the fetuses, and from the villi tissue, amniotic fluid or cord blood of the fetuses using a standard sodium dodecyl sulfate-proteinase K-phenol/chloroform extraction method. PCR combined with Sanger DNA sequencing was performed to validate the pathogenic mutations of 200 fetuses at risk of OI and their parents from 158 families. Allelic analysis of microsatellite markers was applied to exclude the false positive caused by maternal DNA contamination, when both the fetus and the mother harbored the same pathogenic genotype. Results: A total of 83 affected fetuses (83/200, 41.5%) and 12 (12/200, 6.0%) recessive carriers were identified among the 200 fetuses. The 83 affected fetuses included 78 heterozygotes (45 of COL1A1, 32 of COL1A2, one of IFITM5), and 5 compound heterozygotes or homozygotes of recessive OI (two of FKBP10, one of SEC24D, one of WNT1 and one of CRTAP); The 12 recessive carriers included 7 of WNT1, 4 of SERPINF1 and one of SERPINH1. Maternal DNA contamination was excluded from the genomic DNA samples of OI fetuses when their mother with the same affected genotypes. Conclusion: In this study, the authors used an optimized gene diagnosis system of OI to perform prenatal genetic diagnosis to 200 fetuses at high risk of OI, and provided precisely genetic counselling to the OI families.

Objective: To explore the relationship between hemoglobin (Hb) level during the first trimester of pregnancy and gestational diabetes mellitus (GDM). Methods: A total of 1 276 participants, who underwent scheduled prenatal examination and normal singleton delivery at the Fifth People's Hospital of Shanghai and Hospital of Intergrated Chinese and Western Medicine in Minhang District, from January 2016 to May 2018 were included. There were 99 cases of GDM (GDM group) and 1 177 cases of normal (control group) pregnant women.Based on the serum Hb level during the first trimester of pregnancy, participants were divided into three groups, 236 cases of low Hb level group (Hb<110 g/L), 868 cases of normal Hb level group (110 g/L≤Hb<130 g/L), and 172 cases of high Hb level group (Hb≥130 g/L). Maternal clinical data were collected, including Hb level during the first trimester of pregnancy, three-point blood glucose (BG) of oral glucose tolerance test (OGTT) and fasting insulin during the second trimester of pregnancy. Homeostasis model assessment of insulin resistance index (HOMA-IR) and homeostasis model assessment of pancreatic β cell function index (HOMA-β) were used to evaluate insulin resistance and pancreatic β cell function. Results: (1) Hb level during the first trimester of pregnancy in GDM group was significantly higher than that in control group [(123±10),(119±11) g/L, P<0.05]. There were no significant difference in gravidity, parity, index of liver and renal function (all P>0.05). (2) Pre-pregnancy body mass index (BMI), 1-hour BG and 2-hour BG of OGTT were significantly increased in the high Hb level group during the first trimester of pregnancy, which were (23±4) kg/m(2), (7.3±2.0) mmol/L, and (6.5±1.4) mmol/L (P<0.05), respectively. The pre-pregnancy BMI, 1-hour BG and 2-hour BG of the normal or low Hb level group were (22±3) kg/m(2), (6.7±1.6) mmol/L, (6.1±1.2) mmol/L; (22±3) kg/m(2), (6.5±1.5) mmol/L, (5.9±1.1) mmol/L, respectively. There were no statistically significant difference in levels of fasting blood glucose, fasting insulin, HOMA-IR and HOMA-β within 3 groups (all P>0.05). (3) In the high Hb level group, prevalence of pregnancy overweight or obesity and GDM were the highest, which were 37.2%(64/172) and 15.1%(26/172), respectively; the differences were statistically significant (all P<0.05). (4) The serum Hb level in the first trimester was positively related with pre-pregnancy BMI (r=0.130, P<0.05), 1-hour BG (r=0.129, P<0.05), 2-hour BG (r=0.134, P<0.05), fasting insulin (r=0.096, P<0.05), and HOMA-IR (r=0.101, P<0.05).Logistic regression indicated that Hb≥130 g/L during the first trimester of pregnancy was an independent risk factor for GDM (OR=2.799, 95%CI: 1.186-6.604; P<0.05). Conclusion: The high level of Hb (Hb≥130 g/L) during the first trimester of pregnancy is associated with GDM.

Abstract
Surgical margin principle is one of the central surgical principles for head and neck cancers. Negative surgical margin is the primary purpose of surgery for head and neck cancers. This paper is based on the current clinical application of surgical margins of head and neck cancers, and it is proposed that surgical margins of head and neck cancers may be classified into three types: surface margin, deep margin, and tissue interface margin in consideration of surgical exposure of tumors. The classification of surgical margins can make the clinical application and the research of surgical margins of head and neck cancers more systematic and clear.

Abstract
Objective: To analyze the clinical characteristics of hepatic flare and evaluate efficacy of antiviral treatment in pregnant women with chronic HBV infection. Methods: A single-center, open-label, prospective study was conducted, and pregnant women with chronic HBV infection were enrolled. Liver function, HBV serum markers and HBV DNA of pregnant women with chronic HBV infection were reviewed during every 4 to 12 weeks of gestation period. The proportion and clinical characteristics of hepatitis flare during pregnancy were observed. Logistic regression analysis was used to predict hepatic flare in pregnant women with chronic HBV infection. Antiviral therapy with telbivudine (LdT) or tenofovir dipivoxil (TDF) was used to treat hepatic flare during pregnancy. Sequential entecavir (ETV) or TDF was applied after the delivery. Treatment course and drug withdrawal in pregnant women with hepatic flare was the same as those of the general patients with chronic hepatitis B. Liver function, HBV serum markers and HBV DNA were measured in pregnant women with hepatic flare at different time points (4, 12, 24 and 52 weeks). A t-test was used to compare the hepatic flare in pregnant women with and without hepatitis group. HBsAg and HBeAg were used to quantify the receiver operating characteristic (ROC) curve of pregnant women with hepatic flare during pregnancy. Area under the ROC curve was used to calculate the optimal cut-off value corresponding to the maximum sensitivity and specificity of the ROC curve. Results: Of the 220 pregnant women with chronic HBV infection, 55 (25%) had hepatitis flare during pregnancy and received antiviral treatment. Among the 55 women with hepatic flare during gestation, 47 (85.46%) had hepatic flare in the mid-second trimester (12-24 weeks); average peak value of alanine aminotransferase (ALT) was 220.62 U/L, and the average peak value of ALT in 32 cases (58.18%) of pregnant women with hepatic flare was between 2-5 × ULN. HBsAg and HBeAg quantification were significantly lower in pregnant women with hepatic flare during pregnancy than with non-hepatitis (t = -3.745, P < 0.001; t = -2.186, P = 0.030). Multivariate logistic regression analysis showed that pregnant women with HBeAg < 3.065 log10 s/co were 7.576 times more likely to have hepatic flare during pregnancy (95% confidence interval: 3.779-15.190). ALT normalization, undetectable HBV DNA levels, HBeAg loss and HBeAg seroconversion in 55 pregnant women with hepatic flare at 52-week treatment was 100% (55/55), 74.55% (41/55), 47.27% (26/55) and 41.82% (23/55), respectively. HBsAg quantification at 52 weeks was significantly lower than baseline HBsAg quantification (3.32 + 0.37) log(10) IU/ml and (3.95 + 0.40) log(10) IU/ml; t = 8.465, P < 0.001). Conclusion: Hepatic flare often occurs in the second trimester of pregnancy in pregnant women with chronic HBV infection and baseline HBeAg quantification is an independent predictor of hepatic flare. HBeAg seroconversion rate increased at 52 weeks after antiviral therapy.

Abstract
Objective: To investigate whether HBV genotype influences HBV DNA and RNA responses to tenofovir(TDF) and telbivudine(LDT) in pregnant women with HBeAg-positive in Guizhou. Methods: This was a retrospective analysis of 75 pregnant women hepatitis B with HBsAg and HBeAg double-positive(19-38 years old, median age 26 years old), who were enrolled in the Department of Infectious Diseases and Obstetrics Clinic of the Affiliated Hospital of Guizhou Medical University from May 2016 to July 2017.Blood samples were collected at 12-24, 28-32 and 36-40 weeks of pregnancy for analyses of genotype, including hepatitis B surface antigen(HBsAg), hepatitis B e antigen (HBeAg), HBV DNA, HBV RNA and liver function, alanine transaminase(ALT), aspartate transaminase(AST), total bilirubin(TBiL), total bile acids(TBA), cholinesterase(CHE), alkaline phosphatase (ALP). Continuous variable was adopted by means of mean±standard deviation, and categorical variables were used for statistical analysis. Results: The HBV genotype was B in 64.0%(48/75)and C in 36.0%(27/75). The TDF and LDT groups showed no differences in demographic and clinical characteristics, including liver function tests, HBsAg, HBeAg, log(10)HBV DNA and log(10)HBV RNA.TDF groups, pre-treatment: HBV DNA (4.8±2.0), HBV RNA (6.4±1.1); at 4 weeks of treatment: HBV DNA (4.0±0.8), HBV RNA (6.0±0.9); at the end of treatment: HBV DNA (3.1±0.7), HBV RNA (5.5±0.8). LDT groups, pre-treatment HBV DNA (5.1±2.0), HBV RNA(6.5±0.9); at 4 weeks of treatment: HBV DNA (4.4±1.2), HBV RNA(6.5±0.8); at the end of treatment: HBV DNA(3.5±1.2), HBV RNA (6.1±0.7). Compared with pre-treatment (12-24 weeks), the TDF and LDT group showed significant reductions in log(10)(HBV DNA) and log(10)(HBV RNA) at 36-40 weeks ( P<0.05). Under the influence of excluding other variables, the genotype had a certain influence on the HBV RNA load.That was, HBV RNA in patients with the C genome decreased by 0.54 units(log(10)) at the end of the treatment compared to patients with the B genome, and the P value was less than 0.05. Conclusion: B and C genotypes are predominant in pregnant women with hepatitis B in Guizhou Province. B-type viruses are more easily controlled when different genotypes are treated with nucleotide analogues.

Abstract
Objective:To understand the expression of LINC00460 in laryngeal squamous cell carcinoma (LSCC), and to discuss the role of LINC00460 in carcinogenesis and development of laryngeal squamous cell carcinoma. Method:The expression of LINC00460 in 68 laryngeal squamous cell carcinoma tissues and paired adjacent normal tissues were examined by real-time PCR. The relationship between the expression levels of LINC00460 and the clinicopathological features including clinical stage, histological grade, pathological type, and lymph node metastasis in LSCC was analyzed according to the clinical data. Result:The expression of LINC00460 was significantly upregulated in the LSCC tissue compared with that of adjacent normal mucosal tissue (P=0.006). There were no statistical differences of the quantity of LINC00460 expression among supraglottic, glottic and subglottic LSCC (P>0.05). Moreover, LINC00460 had no significant changes in poorly differentiated LSCC when compared with that of well and moderately differentiated LSCC (P>0.05). Furthermore, the expression of LINC00460 in LSCC with lymph node metastasis had no significant changes when compared with that without of lymph node metastasis (P>0.05). Notably, LINC00460 expression in T1+T2 stages patients were significantly lower than T3+T4 stages (P<0.05). Conclusiont:Upregulation of long non-coding RNA LINC00460 might contribute to the carcinogenesis and development of LSCC, furthermore play important biological function.

Abstract
Occupational noise-induced hearing loss (ONIHL) is a prevalent occupational disorder that impairs auditory function in workers exposed to prolonged noise. However, serum microRNA expression in ONIHL subjects has not yet been studied. We aimed to compare the serum microRNA expression profiles in male workers of ONIHL subjects and controls. MicroRNA microarray analysis revealed that four serum microRNAs were differentially expressed between controls (n=3) and ONIHL subjects (n=3). Among these microRNAs, three were upregulated (hsa-miR-3162-5p, hsa-miR-4484, hsa-miR-1229-5p) and one was downregulated (hsa-miR-4652-3p) in the ONIHL group (fold change >1.5 and Pbon value <0.05). Real time quantitative PCR was conducted for validation of the microRNA expression. Significantly increased serum levels of miR-1229-5p were found in ONIHL subjects compared to controls (n=10 for each group; P<0.05). A total of 659 (27.0%) genes were predicted as the target genes of miR-1229-5p. These genes were involved in various pathways, such as mitogen-activated protein kinase (MAPK) signaling pathway. Overexpression of miR-1229-5p dramatically inhibited the luciferase activity of 3′ UTR segment of MAPK1 (P<0.01). Compared to the negative control, HEK293T cells expressing miR-1229-5p mimics showed a significant decline in mRNA levels of MAPK1 (P<0.05). This preliminary study indicated that serum miR-1229-5p was significantly elevated in ONIHL subjects. Increased miR-1229-5p may participate in the pathogenesis of ONIHL through repressing MAPK1 signaling.

Abstract
The acquisition of the oral microbiome is a complex process. We examined how the timing of microbial exposure alters bacterial colonization of the tooth surface. Germ-free mice were conventionalized by exposure to specific pathogen-free (SPF) mice to acquire a commensal microbiome over three distinct 4-week periods, 0-4 weeks of age (Conv0-4w), 4-8 weeks (Conv4-8w), or 8-12 weeks (Conv8-12w). Bacterial DNA was extracted from the tooth surface and analyzed by 16S rDNA sequencing. Total bacteria and inflammatory cytokine expression in gingiva were determined by quantitative real-time polymerase chain reaction. After co-housing with SPF mice, Conv0-4w and Conv4-8w mice had low bacterial diversity, whereas Conv8-12w mice had high bacterial diversity that was similar to that of SPF donor mice, as determined by both operational taxonomic units and the Shannon Index. Cluster analysis with unweighted Unifrac distance also supported these trends. This was surprising as the amount of maturation time, 4 weeks, was equal in all conventionalized mice and tooth eruption was largely completed by 4 weeks. This suggests that host factors that occur after tooth eruption have a significant effect on the microbial tooth colonization.

Abstract
Objective: To investigate the safety, efficacy and prognostic factors of S-1 versus capecitabine in patients with advanced breast cancer (ABC). Methods: From January 1, 2012 to December 31, 2014, 154 ABC patients with pathological diagnosis were separated into two groups: S-1 with or without the 3rd generation chemotherapy drug (group S-1) and capecitabine with or without the 3rd generation chemotherapy drug (Group capecitabine). The efficacy, side effects and prognostic factors were compared between the two groups. Results: There were 70 patients in group S-1 and 84 patients in group capecitabine. The objective response rates (ORR) were 31.4% (22/70) in group S-1 and 28.6% (24/84) in group capecitabine. The disease control rates (DCR) were 74.3% (52/70) and 83.3% (70/84), respectively. There were no significant differences in DCR and ORR between two groups (P>0.05). The DCR of patients treated with capecitabine monotherapy was significantly higher than that of S-1 monotherapy [94.4%(17/18) and 64.0%(16/25), P=0.028]. The median PFS was 7.5 and 8.9 months for the patients in the group S-1 and group capecitabine, with no statistically significant difference (P=0.423). The 1-year survival rates of group S-1 and group capecitabine were 81.4% and 66.7%, respectively, with no significant differences(P=0.020). Univariate analysis showed that ER and/or PR status (P=0.004), T stage (P=0.041), and molecular typing (P=0.046) were associated with PFS. Multivariate analysis showed ER and/or PR status (P=0.034) was an independent prognostic factor related with PFS. The incidence of hemoglobin reduction was 14.3% (10/70) and 36.9% (31/84) in the group S-1 and group capecitabine, and the differences were statistically significant (P=0.002). There was no significant difference in the incidence of leukopenia, neutropenia, thrombocytopenia and hand-foot syndrome between the two groups(P>0.05). Conclusions: S-1 and capecitabine are both effective for advanced breast cancer. Neither ORR nor DCR were significantly different between these two groups. The incidence of gastrointestinal reactions and thrombocytopenia of S-1 was slightly lower than that of capecitabine.

Abstract
Objective: This study was to describe the clinical characteristics of Anti-leucine-rich glioma inactivated 1 protein(LGI1) antibody associated limbic encephalitis. Methods: Clinical data including clinical features, laboratory and radiological findings, treatment and prognosis of the 9 patients were analyzed. Results: In all 9 cases, 6 cases experienced epileptic seizure, 5 cases had psychosis, 7 cases presented with memory impairment, 4 cases showed faciobrachial dystonic seizure, 2 had refractory hyponatremia. One case presented with typically acute Guillain-Barre syndrome (GBS). Anti-LGI1 antibody was detected in 6 cases in cerebrospinal fluid (CSF) samples and 9 in serum samples. Seven cases out of 9 had brain imaging abnormalities. All 9 cases found no evidence of tumors. Eight cases were given immune therapy. During a 1-16 months follow-up, 1 case had complete recovery, 5cases had various degree of sequelae , among whom 4 had memory disturbance and 1 case had changed personality. 2cases were lost to follow-up. Conclusions: Limbic encephalitis is the most common manifestation of anti-LGI1 antibody associated encephalitis. Faciobrachial dystonic seizure (FBDS) is a specific symptom which favors an early diagnosis. Tumor is uncommon to see. The disease has a relatively favorable prognosis while impaired memory can be seen as a common sequelae.

Abstract
OBJECTIVE To explore the association between the tag single nucleotide polymorphism (tag SNP) of the adenylyl cyclase 3 (ADCY3) and the essential hypertension (EH). METHODS From April to July 2013, a total of 1 061 subjects diagnosed with EH and 1 218 control subjects were recruited from Ningbo, Zhejiang Province. Information was collected by face-to-face interview. Twelve tag SNPs were detected by ligase detection reaction technique. RESULTS After adjusted for age, gender, body mass index and other related factors, logistic regression analysis showed that 3 loci (rs11689546, rs7593130, rs2241759)were associated with EH. AG genotype of rs11689546 was associated with 0.494 times lower risk of EH (OR=0.494, 95%CI 0.246-0.993; compared with AA genotype). CT genotype of rs7593130 was associated with 1.596 times higher risk of EH (OR=1.596, 95%CI 1.009-2.524; compared with TT genotype), and CT/CC genotype of rs7593130 was associated with 1.627 times higher risk of EH (OR=1.627, 95%CI 1.034-2.559; compared with TT genotype). AG genotype of rs2241759 was associated with 0.669 times lower risk of EH (OR=0.669, 95%CI 0.503-0.891; compared with AA genotype), and CT/CC genotype of rs2241759 was associated with 0.687 times lower risk of EH (OR=0.687, 95%CI 0.518-0.911; compared with TT genotype). CONCLUSION The polymorphisms of ADCY3 are associated with lower (G allele of the rs11689546 locus and G allele of the rs2241759 locus) or higher (C allele of the rs7593130 locus) risk of essential hypertension.

Abstract
In pursuit of lightweighting of automobiles and low emission of transportation, the efforts to develop high-strength, heat-resistant and fatigue-resistant Al alloys and/or composites have been ongoing. Here we report a novel Al matrix composite with ultrahigh strength reinforced by a three dimensional network of nano-AlN particles for the first time. The in-situ synthesized AlN particles are connected by twinning bonding chains and built up a three dimensional network strengthening Al matrix enormously like the skeleton to human body. The composite containing 16.4wt.% AlN particles shows excellent properties: the ultimate tensile strengths can be up to 518MPa at room temperature and 190MPa at 350 °C. This peculiar performance results from the novel spatial distribution of nano-scale AlN particles. Our findings in this work would help to develop a potential candidate for high-performance heat resistance light-metal based materials.

Abstract
OBJECTIVE To study the feasibility of transplantation of normal rat penile corpus cavernosum and major pelvic ganglion (MPG) into the renal subserous region of a Nu/Nu mouse based on allograft technology. METHODS Penile corpus cavernosum and MPG, harvested from Sprague-Dawley (SD) rats under sterile condition, were transplanted underneath the kidney capsule of Nu/Nu mice through the microsurgery instruments and surgery microscope. The histopathologic changes and cellular proliferation in the transplanted penile corpus cavernosum and MPG were then analyzed at the end of 1week and 4 weeks after transplantation. Histological staining and immunohistochemical staining were used to evaluate the main outcome measures. RESULTS After 1 week, the tissue morphology of the transplanted corpus cavernosum underneath the kidney capsule of Nu/Nu mice was consistent with normal penile corpus cavernosum, and blood could be observed in the penis cavernous sinus of the graft; after 4 weeks, the mophorlogy of the tranplanted corpus cavernosum near the kidney was consistent with normal penile corpus cavernosum, while fibrosis was noteworthy in the graft away from the kidney, but blood could still be seen in the penis cavernous sinus. After 1 week, the tissue morphology of the transplanted MPG was consistent with normal MPG, multiple islet-like cell clusters could be seen in the transplanted MPG in the renal subserous region, and angiogenesis could be observed near the kidney; after 4 weeks, a network of blood vessels was clearly visible away from the kidney, and islet-like cell clusters were still clearly observed in the transplanted MPG. In addition, ki67 positive cells were observed in the transplanted penile corpus cavernosum and MPG after 4 weeks of transplantation, which indicated that there was still cell proliferation activity in the grafts. CONCLUSION The transplanted corpus cavernosum and MPG underneath the kidney capsule of Nu/Nu mice could survive at least 4 weeks. Moreover, the inner structure of the transplanted corpus cavernosum and MPG was close to the normal tissue. The underlining mechanism may be related to the local microenvironment underneath the kidney capsule of Nu/Nu mice and the neovascularization in the transplanted grafts.

Abstract
Rice blast caused by Magnaporthe oryzae is one of the most devastating rice diseases worldwide. To understand the genetic diversity of indica landrace accessions and identify simple sequence repeat (SSR) markers that are associated with blast resistance, a population of 276 indica landraces from across the world was constructed. This population was then used to evaluate the blast-resistance phenotype through artificial inoculation under controlled conditions in 2012 and 2013. The genetic diversity and association of the population with resistance were analyzed by examining the phenotype for 160 SSR markers distributed on 12 rice chromosomes. The 276 accessions were classified into seven groups using model- and distance-based cluster analyses. Associations between SSR markers and blast resistance showed that 26 SSR markers were significantly associated with blast resistance in 2012 and 2013 (P < 0.01) and that the phenotypic variation ranged from 2.68 to 13.11%. Nineteen of the markers associated with blast resistance were located in regions where genes or quantitative trait loci (QTLs) have been previously reported, and seven were newly identified in this study. These results indicate that marker-trait association has potential advantages over classical linkage analysis and QTL mapping, and that these markers could be used for marker-assisted selection in rice blast-resistance-breeding programs.

Abstract
Knowledge of genetic diversity is important to assist breeders in the selection of parental materials and in the design of breeding programs. In this study, we genotyped 348 inbred tomato lines, representing vintage and contemporary fresh-market varieties, by using 52 single nucleotide polymorphisms (SNPs); 45 of these were found to be polymorphic. The average minor allele frequency and unbiased expected heterozygosity were 0.315 and 0.356, respectively. Population structure analysis revealed that contemporary germplasm could be distinctly divided into six subpopulations representing three market classes and breeding programs (pink, green, and red). Vintage germplasm could be separated into at least two subpopulations, and more admixtures were found in vintage lines than in contemporary lines. These findings indicate that contemporary inbred lines are more diversified than vintage inbred lines. AMOVA of vintage and contemporary lines was performed. A significant difference was found (P < 0.01), which explained 17.4% of the total genetic variance. Subsequently, we constructed a core collection using 45 polymorphic SNP markers. The data showed that all alleles were captured by only 2% of lines, indicating that more alleles, as well as rare alleles, could enable more variation to be captured in the core collection. These data allow us to discard redundant inbred tomato lines and to select elite inbred lines, which will accelerate the breeding process.

Abstract
OBJECTIVE To investigate the correlation of occupational stress with the serum levels of immunoglobulins(IgG, IgM, and IgA) and complement(C3 and C4). METHODS In May 2011, convenience sampling and cluster sampling were used to select 225 policemen from a local police station as study subjects. A questionnaire was used to investigate demographic features and occupational stress, and the immunoturbidimetric assay was applied to measure the serum levels of IgG, IgM, IgA, and complement C3 and C4. RESULTS Positive affectivity was positively correlated with the concentration of IgG(r=0.084, P<0.01); positive affectivity, coping strategy, and sleep quality were positively correlated with the concentration of IgM(r= 0.146, 0.155, and 0.203, all P<0.05); negative affectivity was negatively correlated with the concentration of IgM(r=-0.185, P<0.05). Reward and sleep quality were positively correlated with the concentration of C3(r= 0.172 and 0.285, both P<0.05), and negative affectivity was negatively correlated with the concentration of C3 (r=-0.174, P<0.05); sleep quality was positively correlated with the concentration of C4(r= 0.173, P<0.05), and negative affectivity was negatively correlated with the concentration of C4(r=-0.164, P<0.05). The logistic regression analysis revealed that the risks for a reduced concentration of IgG in the groups with high scores of social support and positive affectivity were 0.460 and 0.495 times those in the groups with low scores, while the risk for a reduced concentration of IgM in the group with a high score of coping strategy was 0.482 times that in the group with a low score. CONCLUSION Occupational stress is correlated with the serum levels of immunoglobulins and complement.

Abstract
OBJECTIVE To study the feasibility of transplantation of normal rat penile corpus cavernosum and major pelvic ganglion (MPG) into the renal subserous region of a Nu/Nu mouse based on allograft technology. METHODS Penile corpus cavernosum and MPG, harvested from Sprague-Dawley (SD) rats under sterile condition, were transplanted underneath the kidney capsule of Nu/Nu mice through the microsurgery instruments and surgery microscope. The histopathologic changes and cellular proliferation in the transplanted penile corpus cavernosum and MPG were then analyzed at the end of 1week and 4 weeks after transplantation. Histological staining and immunohistochemical staining were used to evaluate the main outcome measures. RESULTS After 1 week, the tissue morphology of the transplanted corpus cavernosum underneath the kidney capsule of Nu/Nu mice was consistent with normal penile corpus cavernosum, and blood could be observed in the penis cavernous sinus of the graft; after 4 weeks, the mophorlogy of the tranplanted corpus cavernosum near the kidney was consistent with normal penile corpus cavernosum, while fibrosis was noteworthy in the graft away from the kidney, but blood could still be seen in the penis cavernous sinus. After 1 week, the tissue morphology of the transplanted MPG was consistent with normal MPG, multiple islet-like cell clusters could be seen in the transplanted MPG in the renal subserous region, and angiogenesis could be observed near the kidney; after 4 weeks, a network of blood vessels was clearly visible away from the kidney, and islet-like cell clusters were still clearly observed in the transplanted MPG. In addition, ki67 positive cells were observed in the transplanted penile corpus cavernosum and MPG after 4 weeks of transplantation, which indicated that there was still cell proliferation activity in the grafts. CONCLUSION The transplanted corpus cavernosum and MPG underneath the kidney capsule of Nu/Nu mice could survive at least 4 weeks. Moreover, the inner structure of the transplanted corpus cavernosum and MPG was close to the normal tissue. The underlining mechanism may be related to the local microenvironment underneath the kidney capsule of Nu/Nu mice and the neovascularization in the transplanted grafts.

Abstract
The aim of the present study was to determine the anti-proliferative and pro-apoptotic effects of dihydromyricetin (DHM) on the AGS human gastric cancer cells and their underlying mechanisms. The effects of DHM on AGS cells were evaluated by using 3-(4, 5-di-methylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), lactate dehydrogenase, and Annexin V/propidium iodide (PI) double-staining assays. The underlying mechanisms were determined by using quantitative real-time polymerase chain reaction. The results demonstrated that DHM significantly (P < 0.05) inhibited AGS cell proliferation and induced cell cytotoxicity in a dose- and time-dependent manner. Additionally, Annexin V/PI double-staining assay showed that DHM promoted cell apoptosis in both, early and late stages. Furthermore, DHM also regulated the expression of apoptotic genes such as p53 and B-cell lymphoma-2 (bcl-2) in a dose- and time-dependent manner. In conclusion, this is the first report demonstrating the anticancer and pro-apoptosis effects of DHM on AGS human gastric cancer cells. The results strongly suggest that DHM may be a potential therapeutic candidate for the treatment of gastric cancer.
