Abstract
PURPOSE To evaluate the effect of respiratory muscle training on improving lung function in patients with stroke-associated pneumonia. MATERIALS AND METHODS A systematic retrieval was conducted using the databases of the Cochrane Library, PubMed, the Web of Science, Embase, ProQuest, and others. Studies involving patients who received respiratory muscle training with/without a breathing trainer and those who adopted routine post-stroke rehabilitation training were included in the systematic review. The statistical analysis was performed using RevMan 5.3 software. RESULTS Fourteen studies were included involving 850 patients with stroke. According to the results of the meta-analysis, compared with the control group, there were statistically significant differences in forced vital capacity (FVC) measurements (mean difference (MD) = 0.93, p < 0.0001) and improvement values for FEV1/FVC (MD = 0.65, p < 0.00001) in the experimental group. The FEV1 value was higher in the experimental group than in the control group (MD = 5.89, p < 0.0001). Furthermore, respiratory muscle training was superior to routine rehabilitation training for improving the PImax of patients with stroke (MD = 9.20, p < 0.0001). The patients had better respiratory tolerance after respiratory muscle training intervention (MD = 73.40, p < 0.0001). CONCLUSIONS The implementation of respiratory muscle training can improve FVC and FEV lung function indicators, inspiratory muscle strength and the 6-min walk test results in patients with stroke.

Abstract
Background To investigate the prognostic role of pretreatment squamous cell carcinoma antigen (SCCA) in early-stage cervical cancer (CC). Methods We enrolled 487 cases of pathology-proven early-stage [International Federation of Gynecology and Obstetrics (FIGO) I/II] squamous or adenosquamous CC that were treated from 2012 to 2015. Restricted cubic splines (RCS) with a full Cox regression model were used to evaluate the association between SCCA levels and survival outcomes. Recursive partitioning analysis (RPA) was used to construct a risk stratification model for overall survival (OS). The performance of the RPA-based model was assessed using a receiver operating characteristic (ROC) curve. Results RCS analysis revealed an association between SCCA and OS and disease-free survival (DFS); SCCA ⩾2.5 ng/mL was robust for risk discrimination in our cohort. SCCA had an interaction effect with FIGO classification: Patients with FIGO I and SCCA ⩾2.5 ng/mL overlapped with those with FIGO II and SCCA < 2.5 ng/mL for OS [hazard ratio, 1.04 (95% confidence interval (CI): 0.49-2.24), p = 0.903] and DFS [1.05 (0.56-1.98), p = 0.876]. RPA modeling incorporating SCCA (<2.5 ng/mL and ⩾2.5 ng/mL) and FIGO classification divided CC into three prognostic groups: RPA I, FIGO stage I, and SCCA < 2.5 ng/mL; RPA II, FIGO stage I, and SCCA ⩾ 2.5 ng/mL, or FIGO stage II and SCCA < 2.5 ng/mL; and RPA III, FIGO stage II, and SCCA ⩾ 2.5 ng/mL; with 5-year OS of 94.0%, 85.1%, and 73.5%, respectively (p < 0.001). ROC analysis confirmed that the RPA model outperformed the FIGO 2018 stage with significantly improved accuracy for survival prediction [area under the curve: RPA versus FIGO, 0.663 (95% CI: 0.619-0.705] versus 0.621 (0.576-0.664), p = 0.045]. Importantly, the RPA groupings were associated with the efficacy of treatment regimens. Surgery followed by adjuvant treatment had a higher OS (p < 0.01) and DFS (p = 0.024) than other treatments for RPA III, whereas outcomes were comparable among treatment regimens for RPA I-II. Conclusion Herein, the role of SCCA for prognostication was confirmed, and a robust clinicomolecular risk stratification system that outperforms conventional FIGO classification in early-stage squamous and adenosquamous CC was presented. The model correlated with the efficacy of different treatment regimes.

Abstract
Objective: To evaluate the long-term outcomes, failure patterns and prognostic factors of definitive radiotherapy in patients with cervical esophageal carcinoma (CEC). Methods: We retrospectively reviewed the clinical data of 148 CEC patients who treated with definitive radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2001 to December 2017. The median radiation dose was 66 Gy (59.4-70 Gy) and 33.1% of patients received concurrent chemotherapy. The Kaplan-Meier method was used to calculate survival rates. The log rank test was used for survival comparison and univariate prognostic analysis. The Cox model was used for multivariate prognostic analysis. Results: The median follow-up time was 102.6 months. The median survival time, 2- and 5-year overall survival (OS) were 22.7 months, 49.9% and 28.3%. The median, 2- and 5-year progression-free survival were 12.6 months, 35.8% and 25.8%. The 2- and 5-year locoregional recurrence-free survival were 59.1% and 50.8%. The 2- and 5-year distant metastases-free survival were 74.6% and 65.9%. Multivariate analysis showed that EQD(2)>66 Gy was the only independent prognostic indicator for OS (P=0.040). The median survival time and 5-year OS rate significantly improved in patients who received EQD(2)>66 Gy than those who received≤66 Gy (31.2 months vs. 19.2 months, 40.1% vs. 19.1%, P=0.027). A total of 87 patients (58.8%) developed tumor progression. There were 50 (33.8%), 23 (15.5%) and 39 (26.4%) patients developed local, regional recurrence and distant metastases, respectively. Eleven patients (7.4%) underwent salvage surgery, and the laryngeal preservation rate for entire group was 93.9%. Conclusions: Definitive radiotherapy is an effective treatment for cervical esophageal carcinoma with the advantage of larynx preservation. Local recurrence is the major failure pattern. EQD(2)>66 Gy is associated with the improved overall survival.

Abstract
Light plays an essential role in psychobiological and psychophysiological processes, such as alertness. The alerting effect is influenced by light characteristics and the timing of interventions. This meta-analysis is the first to systematically review the effect of light intervention on alertness and to discuss the optimal protocol for light intervention. In this meta-analysis, registered at PROSPERO (Registration ID: CRD42020181485), we conducted a systematic search of the Web of Science, PubMed, and PsycINFO databases for studies published in English prior to August 2021. The outcomes included both subjective and objective alertness. Subgroup analyses considered a variety of factors, such as wavelength, correlated color temperature (CCT), light illuminance, and timing of interventions (daytime, night-time, or all day). Twenty-seven crossover studies and two parallel-group studies were included in this meta-analysis, with a total of 1210 healthy participants (636 (52%) male, mean age 25.62 years). The results revealed that light intervention had a positive effect on both subjective alertness (standardized mean difference (SMD) = –0.28, 95% confidence interval (CI): –0.49 to –0.06, P = 0.01) and objective alertness in healthy subjects (SMD = –0.34, 95% CI: –0.68 to –0.01, P = 0.04). The subgroup analysis revealed that cold light was better than warm light in improving subjective alertness (SMD = –0.37, 95% CI: –0.65 to –0.10, P = 0.007, I2 = 26%) and objective alertness (SMD = –0.36, 95% CI: –0.66 to –0.07, P = 0.02, I2 = 0). Both daytime (SMD = –0.22, 95% CI: –0.37 to –0.07, P = 0.005, I2 = 74%) and night-time (SMD = –0.32, 95% CI: –0.61 to –0.02, P = 0.04, I2 = 0) light exposure improved subjective alertness. The results of this meta-analysis and systematic review indicate that light exposure is associated with significant improvement in subjective and objective alertness. In addition, light exposure with a higher CCT was more effective in improving alertness than light exposure with a lower CCT. Our results also suggest that both daytime and night-time light exposure can improve subjective alertness.

Abstract
Purpose Using real-world evidence, this study aimed to identify elderly nasopharyngeal carcinoma (NPC) patients who would benefit from chemotherapy. Methods and materials 1714 elderly NPC patients between April 2007 and December 2017 were identified. Recursive partitioning analysis (RPA) was used to generate risk-stratified outcomes. Prognostic factors were performed for individual comparisons of different risk groups to assess chemotherapy benefits. Results The median follow-up was 59.3 (0.39–170.09) months. Epstein Barr virus (EBV) DNA and T stage were included in the RPA-generated risk stratification, categorizing patients into a good-prognosis group (EBV DNA ≤ 4000 copies/mL & T1–2), and a poor-prognosis group (EBV DNA ≤ 4000 copies/mL & T3–4 and EBV DNA > 4000 copies/mL & any T). Overall survival (OS) was significantly higher in the good-prognosis group compared with the training set (HR = 0.309, 95% CI 0.184–0.517; P < 0.001), and validated in the testing set (HR = 0.276, 95% CI 0.113–0.670; P = 0.002). In the poor-prognosis group, a significantly improved OS for chemoradiotherapy (CRT) compared with RT alone was observed (HR = 0.70, 95% CI 0.55–0.88; P = 0.003). Patients who received induction chemotherapy (IC) + concurrent chemoradiotherapy (CCRT) and CCRT had a significantly improved OS compared with RT alone (IC + CCRT vs. RT alone: P = 0.002; CCRT vs. RT alone: P = 0.008) but not in the IC + RT group (P = 0.306). The 5-year OS for CRT versus RT-alone with ACE-27 scores of 0, 1 and 2 were 76.0% versus 70.0% (P = 0.014), 80.5% versus 68.2% (P = 0.150) and 58.5% versus 62.2% (P = 0.490), respectively; for those aged 60–64, 65–70 and ≥ 70 years old they were 80.9% versus 75.9% (P = 0.068), 73.3% versus 63.4% (P = 0.270) and 64.8% versus 67.1% (P = 0.820), respectively. Conclusions For elderly NPC patients a simple screening cutoff for chemotherapy beneficiaries might be EBV DNA < 4000 copies/ml & T3–4 and EBV DNA ≥ 4000 copies/ml & any T, but not for those > 70 years old and with an ACE-27 score > 1. IC + CCRT and CCRT were effective forms of chemotherapy. Supplementary Information The online version contains supplementary material available at 10.1186/s13014-022-02095-2.

Abstract
Objective: To analyze the efficacy of sinonasal adenoid cystic carcinoma (ACC) with perineural invasion (PNI), and explore the prognostic value of PNI on sinonasal adenoid cystic carcinoma. Methods: The clinical data of 105 patients with sinonasal ACC admitted to Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2016 were retrospectively reviewed. All patients were restaged according to American Joint Committee on Cancer 8th edition. Follow-up visits were conducted to obtain information of treatment failure and survival outcome. The Log rank test was used for univariate analysis of prognostic factors, and Cox regression model was used for multivariate prognostic analysis. Results: The maxillary sinus (n=59) was the most common primary site, followed by the nasal cavity (n=38). There were 93 patients with stage Ⅲ-Ⅳ. The treatment modalities included surgery alone (n=14), radiotherapy alone (n=13), preoperative radiotherapy plus surgery (n=10), and surgery plus postoperative radiotherapy (n=68). The median follow-up time was 91.8 months, the 5-year local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 72.6%, 73.0%, 52.9% and 78.0%, respectively. There were 33 patients (31.4%) with PNI-positive. The 5-year DMFS, PFS, and OS rates of PNI-positive group were 53.7%, 29.4% and 56.5%, respectively, which were significantly inferior to those of PNI-negative group (80.8%, 63.0% and 86.8%, respectively, P<0.05), while there was no significant difference in the 5-year LC rate between both groups (64.5% vs 76.5%, P=0.273). The multivariate Cox regression analysis showed PNI was one of the poor prognostic factors of DMFS (HR=3.514, 95%CI: 1.557-7.932), PFS (HR=2.562, 95%CI: 1.349-4.866) and OS (HR=2.605, 95%CI: 1.169-5.806). Among patients with PNI-positive, the 5-year LC, PFS and OS rates of patients received surgery combined with radiotherapy were 84.9%, 41.3% and 72.7%, respectively, which were significantly higher than 23.3%, 10.0% and 26.7% of patients receiving surgery or radiotherapy alone (P<0.05). Conclusion: The presence of PNI increases the risk of distant metastasis in patients with sinonasal ACC. Compared with patients with PNI-negative, the prognosis of patients with PNI-positive is relatively poor, and surgery combined with radiotherapy for PNI-positive sinonasal ACC results in good clinical outcomes.

Abstract
PURPOSE To develop predictive models with dosimetric and clinical variables for temporal lobe injury (TLI) in nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS Data of 8194 NPC patients who received IMRT-based treatment were retrospectively reviewed. TLI was diagnosed by magnetic resonance imaging. Dosimetric factors were selected by penalized regression and machine learning, with area under the receiver operating curve (AUC) calculated. Cox proportional hazards models containing the most predictive dosimetric factor with/without clinical variables were performed. A nomogram was generated as a visualization of Cox regression for predicting TLI-free survival. RESULTS During median follow-up of 66.8 months (interquartile range [IQR] 54.2-82.2 months), 12.1% of patients (989/8194) developed TLI. Median latency from IMRT to TLI was 36 months (IQR 28-47 months). D0.5cc (dose delivered to 0.5-cm3 temporal-lobe volume) was the most predictive dosimetric factor (AUC: 0.799). Tolerance dose for 5% and 50% probabilities to develop TLI in 5 years were 65.06 Gy (95% confidence interval [CI]: 64.19-65.92) and 89.75 Gy (95% CI: 87.39-92.11), respectively. A nomogram comprising age, T stage, and D0.5cc significantly outperformed the model with only D0.5cc in predicting TLI (C-index: 0.78 vs. 0.737 in train set; 0.775 vs. 0.73 in test set; both P < 0.001). The nomogram-defined high-risk group had worse 5-year TLI-free survival. CONCLUSIONS D0.5cc of 65.06 Gy was the tolerance dose of the temporal lobe. Reducing D0.5cc decreased risk of TLI, especially in older patients with advanced T stage. The nomogram could predict TLI precisely and allow individualized follow-up management.

Abstract
Previous studies have shown that Lycium barbarum polysaccharide, the main active component of Lycium barbarum, exhibits anti-inflammatory and antioxidant effects in treating neurological diseases. However, the therapeutic action of Lycium barbarum polysaccharide on depression has not been studied. In this investigation, we established mouse models of depression using aversive stimuli including exposure to fox urine, air puff and foot shock and physical restraint. Concurrently, we administered 5 mg/kg per day Lycium barbarum polysaccharide-glycoprotein to each mouse intragastrically for the 28 days. Our results showed that long-term exposure to aversive stimuli significantly enhanced depressive-like behavior evaluated by the sucrose preference test and the forced swimming test and increased anxiety-like behaviors evaluated using the open field test. In addition, aversive stimuli-induced depressed mice exhibited aberrant neuronal activity in the lateral habenula. Importantly, concurrent Lycium barbarum polysaccharide-glycoprotein treatment significantly reduced these changes. These findings suggest that Lycium barbarum polysaccharide-glycoprotein is a potential preventative intervention for depression and may act by preventing aberrant neuronal activity and microglial activation in the lateral habenula. The study was approved by the Jinan University Institutional Animal Care and Use Committee (approval No. 20170301003) on March 1, 2017.

Abstract
BACKGROUND Head and neck adenoid cystic carcinoma (ACC) is a rare malignant tumor that is prone to local recurrence. The NCCN Guidelines for Head and Neck Cancers recommend that all patients with ACC receive postoperative radiotherapy (PORT). However, whether PORT can improve local control and which patients can benefit from PORT are unknown. This study aimed to assess the role of PORT and provide individualized suggestions for postoperative therapy in patients with ACC. PATIENTS AND METHODS We retrospectively reviewed patients with nonmetastatic head and neck ACC who underwent surgery with or without PORT. Recursive partitioning analysis (RPA) was performed to categorize the patients and predict local recurrence-free survival (LRFS). The survival outcome was compared between non-PORT and PORT groups. RESULTS A total of 319 patients were included. PORT was identified as a prognostic factor for LRFS in univariate (P=.01) and multivariate analysis (P<.01). However, it did not improve distant metastasis-free survival, disease-free survival, or overall survival in univariate analysis. RPA categorized patients into 3 prognostic groups: low-risk (negative margin, T1-T2, primary location = major or minor salivary gland), intermediate-risk (negative margin, T1-T2, primary location = other locations instead of a major or minor salivary gland; negative margin, T3-T4; positive margin, without bone invasion), and high-risk (positive margin, with bone invasion). Significant LRFS improvements in the PORT group were observed among intermediate-risk (P<.01) and high-risk patients (P<.05). LRFS improvements among low-risk patients were relatively insignificant (P=.10). CONCLUSIONS PORT was shown to be a positive prognostic factor for improved LRFS in ACC. Furthermore, PORT could significantly improve LRFS in intermediate-risk and high-risk patients with ACC, but whether low-risk patients could benefit from PORT needs further study.

Abstract
We investigated the clinical characteristics, prognostic factors, and post-recurrence prognostic factors of early- and late-recurrence patients for nasopharyngeal carcinoma (NPC) after definitive intensity-modulated radiation therapy (IMRT). This was a single-center retrospective analysis of patients in China from January 2010 to December 2015. The prognostic factors for overall survival (OS) and post-recurrence OS of early- and late-recurrence patients were identified using univariate and multivariate Cox regression analyses. Of the 9,468 patients included, 409 (4.3%), 325 (3.4%), and 182(1.9%) developed purely local recurrence, purely regional recurrence, and locoregional recurrence during follow-up, respectively. In the purely local recurrence group, 192 patients (46.9%) developed early local recurrence (ETR), and 217 patients (53.1%) developed late local recurrence (LTR). Of the 192 ETR patients, multivariate Cox regression analysis revealed that age and gender were independent risk factors of OS, and post-recurrence best supportive treatment (PRBST) was associated with poorer post-recurrence OS. Of the 217 LTR patients, the results revealed that baseline value of EBV-DNA was an independent risk factor for OS, while PRBST was associated with poorer post-recurrence OS. In the purely regional recurrence group, 183 patients (56.3%) developed early regional recurrence (ENR), and 142 patients (43.7%) developed late regional recurrence (LNR). Of the 183 ENR patients, multivariate Cox regression analysis revealed that alcohol abuse and TNM stage were independent risk factors of OS, while alcohol drinkers and PRBST were associated with poorer post-recurrence OS. Of the 142 LNR patients, PRBST was associated with poorer post-recurrence OS. In the locoregional recurrence group, 87 patients (47.8%) developed early locoregional recurrence (ELR), and 95 patients (52.2%) developed late locoregional recurrence (LLR). Of the 87 ELR patients, multivariate Cox regression analysis revealed that N stage and TNM stage were independent risk factors of OS, and N2/3 stage and PRBST were associated with poorer post-recurrence OS. Of the 95 LLR patients, the results revealed that T stage was an independent risk factor for OS, while T3/4 stage and PRBST were associated with poorer post-recurrence OS. Patients with LTR/LNR/LLR demonstrate significantly better OS compared with patients with ETR/ENR/ELR, Nevertheless, post-recurrence OS between patients with ETR/ENR/ELR and LTR/LNR/LLR was not significantly different.

Abstract
The optimal post-treatment surveillance strategy that can detect early recurrence of a cancer within limited visits remains unexplored. Here we adopt nasopharyngeal carcinoma as the study model to establish an approach to surveillance that balances the effectiveness of disease detection versus costs. A total of 7,043 newly-diagnosed patients are grouped according to a clinic-molecular risk grouping system. We use a random survival forest model to simulate the monthly probability of disease recurrence, and thereby establish risk-based surveillance arrangements that can maximize the efficacy of recurrence detection per visit. Markov decision-analytic models further validate that the risk-based surveillance outperforms the control strategies and is the most cost-effective. These results are confirmed in an external validation cohort. Finally, we recommend the risk-based surveillance arrangement which requires 10, 11, 13 and 14 visits for group I to IV. Our surveillance strategies might pave the way for individualized and economic surveillance for cancer survivors.

Abstract
Background Significance of plasma Epstein-Barr virus deoxyribonucleic acid (EBV DNA)-a proven robust indicator for nasopharyngeal carcinoma (NPC)-is not yet clarified in risk stratification of metastatic NPC (mNPC). We aim to establish effective M1 stage subdivisions in mNPC by integrating radiological features and EBV DNA at diagnosis of metastasis (mEBV DNA). Methods The study comprised 1,007 mNPC patients, including 817 metachronous mNPC (mmNPC) patients randomized into training (n=613) and internal validation (n=204) cohorts, and 190 synchronous mNPC (smNPC) patients defined as smNPC validation cohort. Primary clinical end-point was overall survival (OS). Covariate inclusion to recursive partitioning analysis (RPA)-generated risk stratification was qualified by a multivariable two-sided P<0.05. Performances of different models were compared using area under ROC curve (AUC), Harrell's concordance index (c-index) and Akaike information criterion (AIC). Results Compared with other simply image-based models, the ultimate RPA-EBV-stage presented a best performance [c-index =0.68 (training), 0.70 (internal validation), 0.64 (smNPC validation); AUC =0.69 (training), 0.72 (internal validation), 0.70 (smNPC validation)]: M1a (low mEBV DNA + oligo lesion), M1b (low mEBV DNA + multiple lesions), M1c (high mEBV DNA + no liver involvement), and M1d (high mEBV DNA + liver involvement). Corresponding 3-year OS rates were 49.9%, 33.4%, 22.6%, and 6.7%, respectively (P<0.001). In mmNPC patients, compared with chemotherapy alone, addition of local treatment demonstrated superiority in M1a and M1b; systemic therapy combined with targeted therapy conferred benefit on patients of M1c and M1d (P<0.05). Conclusions This RPA-EBV-stage provided favorable prognostic value for survival outcomes and could assist clinical and investigative management. Low-risk patients are considered suitable candidate for curative local treatment, and high-risk patients are recommended to undergo intensive systemic treatment.

Abstract
Alternative splicing (AS) has emerged as a key event in tumor development and microenvironment formation. However, comprehensive analysis of AS and its clinical significance in head and neck squamous cell carcinoma (HNSC) is urgently required. Methods: Genome-wide profiling of AS events using RNA-Seq data from The Cancer Genome Atlas (TCGA) program was performed in a cohort of 464 patients with HNSC. Cancer-associated AS events (CASEs) were identified between paired HNSC and adjacent normal tissues and evaluated in functional enrichment analysis. Splicing networks and prognostic models were constructed using bioinformatics tools. Unsupervised clustering of the CASEs identified was conducted and associations with clinical, molecular and immune features were analyzed. Results: We detected a total of 32,309 AS events and identified 473 CASEs in HNSC; among these, 91 were validated in an independent cohort (n = 15). Functional protein domains were frequently altered, especially by CASEs affecting cancer drivers, such as PCSK5. CASE parent genes were significantly enriched in pathways related to HNSC and the tumor immune microenvironment, such as the viral carcinogenesis (FDR < 0.001), Human Papillomavirus infection (FDR < 0.001), chemokine (FDR < 0.001) and T cell receptor (FDR < 0.001) signaling pathways. CASEs enriched in immune-related pathways were closely associated with immune cell infiltration and cytolytic activity. AS regulatory networks suggested a significant association between splicing factor (SF) expression and CASEs and might be regulated by SF methylation. Eighteen CASEs were identified as independent prognostic factors for overall and disease-free survival. Unsupervised clustering analysis revealed distinct correlations between AS-based clusters and prognosis, molecular characteristics and immune features. Immunogenic features and immune subgroups cooperatively depict the immune features of AS-based clusters. Conclusion: This comprehensive genome-wide analysis of the AS landscape in HNSC revealed novel AS events related to carcinogenesis and immune microenvironment, with implications for prognosis and therapeutic responses.

Abstract
OBJECTIVE To develop a big data intelligence platform for secondary use of electronic health records (EHRs) data to facilitate research for nasopharyngeal cancer (NPC). METHODS This project was launched in 2015 and carried out by the cooperation of an academic cancer centre and a technology company. Patients diagnosed with NPC at Sun Yat-sen University Cancer Centre since January 2008 were included in the platform. Standard data elements were established to defined 981 variables for the platform. For each patient, data from 13 EHRs systems were extracted, integrated, structurized and normalized. Eight functional modules were constructed for the platform to facilitate the investigators to identify eligible patients, establish research projects, conduct statistical analysis, track the follow-up, search literature, etc. RESULTS From January 2008 to December 2018, 54,703 patients diagnosed with NPC were included. Of these patients, 39,058 (71.4%) were male, and 15,645 (28.6%) were female; median age was 47 (interquartile range, 39-55) years. Of 981 variables, 341 were obtained from data structurization and normalization, of which 68 were generated by interacting multiple data sources via well-defined logical rules. The average precision rate, recall rate and F-measure for 341 variables were 0.97 ± 0.024, 0.92 ± 0.030, and 0.94 ± 0.027 respectively. The platform is regularly updated every seven days to include new patients and add new data for existing patients. Up to now, eight big data-driven retrospective studies have been published from the platform. CONCLUSION Our big data intelligence platform demonstrates the feasibility of integrating EHRs data of routine healthcare, and offers an important perspective on real-world study of NPC. The continued efforts may be focus on data sharing among multiple hospitals and publicly releasing of data files. ADVANCES IN KNOWLEDGE Our big data intelligence platform is the first disease-specific data platform for NPC research. It incorporates comprehensive EHRs data from routine healthcare, which can facilitate real-world study of NPC in risk stratification, decision-making and comorbidities management.

Abstract
Long noncoding RNAs (lncRNA) play important roles in the tumorigenesis and progression of cancers. However, the clinical significance of lncRNAs and their regulatory mechanisms in nasopharyngeal carcinogenesis (NPC) are largely unknown. Here, based on a microarray analysis, we identified 384 dysregulated lncRNAs, of which, FAM225A was one of the most upregulated lncRNAs in NPC. FAM225A significantly associated with poor survival in NPC. N(6)-Methyladenosine (m6A) was highly enriched within FAM225A and enhanced its RNA stability. FAM225A functioned as an oncogenic lncRNA that promoted NPC cell proliferation, migration, invasion, tumor growth, and metastasis. Mechanistically, FAM225A functioned as a competing endogenous RNA (ceRNA) for sponging miR-590-3p and miR-1275, leading to the upregulation of their target integrin β3 (ITGB3), and the activation of FAK/PI3K/Akt signaling to promote NPC cell proliferation and invasion. In summary, our study reveals a potential ceRNA regulatory pathway in which FAM225A modulates ITGB3 expression by binding to miR-590-3p and miR-1275, ultimately promoting tumorigenesis and metastasis in NPC. SIGNIFICANCE: These findings demonstrate the clinical significance of the lncRNA FAM225A in nasopharyngeal carcinoma (NPC) and the regulatory mechanism involved in NPC development and progression, providing a novel prognostic indicator and promising therapeutic target.

Abstract
BACKGROUND To identify a radiomics signature to predict local recurrence in patients with non-metastatic T4 nasopharyngeal carcinoma (NPC). METHODS A total of 737 patients from Sun Yat-sen University Cancer Center (training cohort: n = 360; internal validation cohort: n = 120) and Wuzhou Red Cross Hospital (external validation cohort: n = 257) underwent feature extraction from the largest axial area of the tumor on pretreatment magnetic resonance imaging scans. Feature selection was based on the prognostic performance and feature stability in the training cohort. Radscores were generated using the Cox proportional hazards regression model with the selected features in the training cohort and then validated in the internal and external validation cohorts. We also constructed a nomogram for predicting local recurrence-free survival (LRFS). FINDINGS Eleven features were selected to construct the Radscore, which was significantly associated with LRFS. For the training, internal validation, and external validation cohorts, the Radscore (C-index: 0.741 vs. 0.753 vs. 0.730) outperformed clinical prognostic variables (C-index for primary gross tumor volume: 0.665 vs. 0.672 vs. 0.577; C-index for age: 0.571 vs. 0.629 vs. 0.605) in predicting LRFS. The generated radiomics nomogram, which integrated the Radscore and clinical variables, exhibited a satisfactory prediction performance (C-index: 0.810 vs. 0.807 vs. 0.753). The nomogram-defined high-risk group had a shorter LRFS than did the low-risk group (5-year LRFS: 73.6% vs. 95.3%, P < .001; 79.6% vs 95.8%, P = .006; 85.7% vs 96.7%, P = .005). INTERPRETATION The Radscore can reliably predict LRFS in patients with non-metastatic T4 NPC, which might guide individual treatment decisions. FUND: This study was funded by the Health & Medical Collaborative Innovation Project of Guangzhou City, China.

Abstract
OBJECTIVES Induction chemotherapy (IC) now is gaining recognition for the treatment of nasopharyngeal carcinoma (NPC). The current study was conducted to examine the association between prognosis and the interval between IC and radiotherapy (RT) in NPC patients. METHODS Patients with newly diagnosed, non-metastatic NPC who were treated with IC followed by RT from 2009 to 2012 were identified from an inpatient database. Overall survival (OS), disease-free survival (DFS), distant metastasis-free survival (DMFS) and locoregional recurrence-free survival (LRFS) were compared between those with interval ≤ 30 and > 30 days by Kaplan-Meier and log-rank analyses; Cox modeling was used for multivariable analysis. RESULTS A total of 668 patients met inclusion criteria with median follow-up of 64.4 months. Patients were categorized by interval: 608 patients with interval ≤ 30 days, and 60 with interval > 30 days. The 5-year OS, DFS, DMFS and LRFS rates were 86.6, 78.2, 88.0 and 89.8% for patients with interval ≤ 30 days, respectively, and 69.2, 64.5, 71.2 and 85.1% for patients with interval > 30 days, respectively. The prolonged interval was a risk factor for OS, DFS and DMFS with adjusted hazard ratios (95% confidence intervals) were 2.44 (1.48-4.01), 1.99 (1.27-3.11) and 2.62 (1.54-4.47), respectively. CONCLUSIONS Prolonged interval > 30 days was associated with a significantly higher risk of distant metastasis and death in NPC patients. Efforts should be made to avoid prolonged interval between IC and RT to minimize the risk of treatment failure.

Abstract
Antimicrobial peptides (AMPs) are produced by the stimulated humoral immune system. Most mature AMPs contain less than 50 amino acid residues. Some of them are generated from proproteins upon microbial challenges. Here, we report the antimicrobial activities of a proline-rich proprotein, named SlLebocin1 (SlLeb1), from the tobacco cutworm Spodoptera litura. SlLebocin1 cDNA contains a 477-bp open reading frame (ORF). It is mainly expressed in hemocytes and the midgut in naïve larvae. The transcript level was significantly induced in hemocytes but repressed in the midgut and fat body by bacterial challenges. The proprotein contains 158 amino acids with 3 RXXR motifs that are characteristic of some Lepidopteral lebocin proproteins. Four peptides corresponding to the predicted processed fragments were synthesized chemically, and their antimicrobial activities against two Gram-negative and two Gram-positive bacterial strains were analyzed. The peptides showed differential antimicrobial activities. For Escherichia coli and Bacillus subtilis, only the C-terminal fragment (124-158) showed strong inhibitory effects. For Staphylococcus aureus, all peptides showed partial inhibitions. None of them inhibited Serratia marcescens. Bacterial morphologies were examined by the scanning electron microscopy and confocal laser scanning microscopy. The antimicrobial peptides either disrupted cellular membrane or inhibited cell division and caused elongated/enlarged morphologies. The results may provide ideas for designing novel antibiotics.

Abstract
BACKGROUND AND PURPOSE Lacking quantitative evaluations of competing risk data of nasopharyngeal carcinoma (NPC), we aimed to evaluate the probability of NPC- and other cause-specific mortality (NPC-SM; OCSM) and develop competing risk nomograms to quantify survival differences. MATERIAL AND METHOD Using the institutional big-data intelligence platform, 7251 NPC patients undergoing intensity-modulated radiotherapy between 2009-2014 were identified to establish nomograms based on Fine and Gray's competing risk analysis. RESULTS The 5-year NPC-SM and OCSM of the cohort were 13.1% and 1.2%, respectively, and elevated 5-year OCSMs were observed in patients aged ≥65 years (5.5%) or with severe comorbidities (4.3%). Age was most predictive of OCSM: patients aged 55-64 and ≥65 years exhibited subdistribution hazard ratios (SHRs) of 2.70 (95% confidence interval [CI], 1.64-4.4; P < .001) and 5.78 (95% CI, 3.32-10.08; P < .001), respectively. Comorbidity measured using the Charlson Comorbidity Index (CCI) was also strongly predictive of OCSM: patients with CCI scores of 1 and ≥2 exhibited SHRs of 2.33 (95% CI, 1.46-3.71; P < .001) and 2.58 (95% CI, 1.16-5.73; P = .020), respectively. All validated factors were integrated into the competing nomograms: age, sex, histology type, tumor and node stages, plasma Epstein-Barr virus-DNA level, lactate dehydrogenase level, and C-reactive protein (CRP) level into the NPC-SM model (concordance [c]-index = 0.743); and age, CCI, Albumin level, and CRP level into the OCSM model (c-index = 0.793). CONCLUSION OCSM represents a significant competing event for NPC-SM in elderly patients and patients with comorbidities. We present the first prognostic nomograms to quantify competing risks, which may help to tailor individualized treatment.

Abstract
Resveratrol, a natural phenolic compound, provides neuroprotective effects, however, the specific mechanisms of action remain to be elucidated. The purpose of the present study was to examine the neuroprotective effect of resveratrol on spinal cord injury (SCI) and the potential molecular mechanisms of action. A rat model of SCI was induced using Allen's method, and resveratrol (100 mg/kg) was intraperitoneally injected 1 day following surgery. The recovery of neurological function was assessed using the Basso, Beattie, Bresnahan scoring system and an inclined plane test. The concentrations of pro‑ and anti‑inflammatory factors were measured using ELISA. The expression and location of autophagy markers were measured using western blot and immunofluorescence analyses. The results suggested that resveratrol administration resulted in functional improvement of locomotor activity and reduced neuroinflammation following the induction of SCI. In addition, autophagy was activated following SCI, as demonstrated by the significantly increased ratio of microtubule‑associated protein light chain 3 (LC3)‑II/LC3‑I and expression of Beclin‑1 in the injured spinal cord. Of note, the enhancement of phosphorylated (p)‑AMP‑activated protein kinase (AMPK) and the reduction of p‑mammalian target of rapamycin (mTOR) following SCI indicated that the SCI‑induced activation of autophagy was associated with the AMPK/mTOR signaling pathway. Resveratrol treatment further enhanced the activation of autophagy via the AMPK/mTOR pathway following SCI. By contrast, the autophagic inhibitor, 3‑methyladenine, partially inhibited the neuroprotective effects of resveratrol treatment. Together, these findings suggested that resveratrol promoted functional recovery and inhibited neuroinflammation through the activation of autophagy mediated by the AMPK/mTOR pathway following SCI.

Abstract
Objectives: To analyze and understand the risk factors related to HIV new infections among men who have sex with men (MSM). Methods: A longitudinal observational study among MSM was conducted to collect information on HIV related behaviors and sero-conversion. Univariate and multivariate generalized estimating equations (GEE) were used to discuss the risk factors for HIV new infection. Results: A total number of 4 305 MSM were followed during 2013-2015. Among those self-reported MSM who are seeking partners on the Interner tended to have higher proportion on receptive anal intercourse and consistent condom use during anal intercourse than the subgroups seeking their partners in gay bars or bathrooms. HIV incidence among followed MSM during the study period appeared as 4.3/100 person years, with adjusted RR (aRR) of HIV infection for receptive anal intercourse as group 2.20 (95% CI: 1.49-3.24) times than that of insertion anal intercourse group. Those who used rush-poppers (aRR=1.55, 95% CI: 1.10-2.17), unprotected anal intercourse (aRR=2.24, 95%CI: 1.62-3.08), and those with syphilis infection (aRR=2.95, 95%CI: 2.00-4.35) were also risk factors for HIV new infections. After controlling other factors, the relationship between the ways of seeking partners and HIV new infection was not statistical significant. Conclusion: Risk factors for HIV new infection among MSM appeared complex and interactive, suggesting that further studies are needed to generate tailored strategies for the prevention of HIV epidemic among MSM population.

Abstract
Background Maffucci syndrome is a congenital, non-hereditary mesodermal dysplasia characterized by multiple enchondromas and hemangiomas. The presence of visceral vascular lesions in this syndrome is exceedingly rare. Case presentation We report a 26-year-old female who was diagnosed with Maffucci syndrome along with sclerosing angiomatoid nodular transformation (SANT) of the spleen. The patient underwent a laparoscopic splenectomy. Immunostaining of the excised specimen revealed 3 distinct types of vessels in the angiomatoid nodules: CD34−/CD8−/CD31+ small veins, CD34−/CD8+/CD31+ sinusoids, and CD34+/CD8−/CD31+ capillaries, leading to the diagnosis of SANT of the spleen. Conclusions This case reports the first patient in the literature exhibiting the features of Maffucci syndrome along with SANT of the spleen. The spleen is probably a predilection site of visceral vascular lesions in this syndrome with a proportion of 4 out of 14. An abdominal Computed Tomography (CT) scan is recommended for any cases of abdominal discomfort. Surgical excision is usually sufficient because of the relatively benign behavior of SANT, however, a more aggressive follow-up is proposed due to the high risk of malignant transformation of enchondromas and development of other neoplasms associated with this syndrome. Further studies are required to reveal its genetic basis for comprehensive prognosis evaluation and therapeutic guidance.

Abstract
Chigger mites are parasites of rodents and other vertebrates, invertebrates, and other arthropods, and are the only vectors of scrub typhus, in addition to other zoonoses. Therefore, investigating their distribution, diversity, and seasonal abundance is important for public health. Rodent surveillance was conducted at 6 districts in Shandong Province, northern China (114–112°E, 34–38°N), from January to December 2011. Overall, 225/286 (78.7%) rodents captured were infested with chigger mites. A total of 451 chigger mites were identified as belonging to 5 most commonly collected species and 3 genera in 1 family. Leptotrombidium scutellare and Leptotrombidium intermedia were the most commonly collected chigger mites. L. scutellare (66.2%, 36.7%, and 49.0%) was the most frequently collected chigger mite from Apodemus agrarius, Rattus norvegicus, and Microtus fortis, respectively, whereas L. intermedia (61.5% and 63.2%) was the most frequently collected chigger mite from Cricetulus triton and Mus musculus, respectively. This study demonstrated a relatively high prevalence of chigger mites that varied seasonally in Shandong Province, China.

Abstract
OBJECTIVE To conduct an analysis of the epidemiological changes in malaria that have occurred in Shanxian county from 2002 to 2016. METHODS A retrospective study was conducted and data were collected from web-based reporting system to explore the epidemiological characteristics in Shanxian county from 2002 to 2016. All individual case information was obtained from village malaria servicers organized by the local Shandong Institute of Parasitic Diseases. RESULTS A total of 133 cases were identified as malaria in Shanxian county during this period, including 124 indigenous cases (93.2%) and 9 imported cases (6.8%). The 124 indigenous malaria cases were infected with Plasmodium vivax (P. vivax), whereas 7 of the 9 confirmed imported cases were infected with Plasmodium falciparum (P. falciparum), 1 was infected with Plasmodium ovale (P. ovale) and 1 patient was infected with P. falciparum mixed with P. vivax. The total number of malaria cases included 86 males (64.7%) and 47 females (35.3%). Age of the patients ranged from 1 to 83 years, although most (64.7%) infections occurred in the 21-to 60-year-old age group. Remarkably, 117 of the total malaria cases (98.0%) were reported from 2006 to 2011. The epidemic season was from June to October, with the peak occurring yearly from July to September. The most common occupation of the infected patients was farmer. In total, 58.1% of the cases occurred in 3 townships, namely, Fugang, Huanggang and Caozhuang. CONCLUSIONS In Shanxian county, the local malaria incidence experienced an emerge-peak-control-eliminate status. However, due to the numbers of migrant labourers returning from Africa, imported cases were continuous and presented an increasing annual trend, which became a non-negligible and a significant impediment for malaria elimination. Therefore, the need to eliminate instances of malaria reintroduction to receptive malaria-free areas should drive strategies to align with the epidemiological changes.

Abstract
Background Descemet’s membrane detachment (DMD) is one of the most serious complications of modern cataract surgery. We present an alternative technique for management of DMD with a review of the literature on current strategies for the treatment of DMD. Case presentation A 74-year-old woman developed DMD after phacoemulsification and failed the first descemetopexy with air tamponade. An alternative method was used to drain the pre-descematic fluid and reposition the detached Descemet’s membrane in this rare case. This technique involved completely filling the anterior chamber with an intracameral air injection, followed by using a 23-gauge needle to puncture the peripheral cornea to drain the pre-descematic fluid. The Descemet’s membrane was completely reattached to the stroma during the follow-up. Conclusions Drainage of pre-descematic fluid combined with intracameral air tamponading was used as an alternative surgical option for the management of this severe case of DMD.

Abstract
BACKGROUND Chemotherapy, target therapy, and immunotherapy are increasingly being used in the systematic treatment of nasopharyngeal carcinoma (NPC), during which the occurrence of hepatitis B virus (HBV) reactivation might increase. However, data regarding HBV screening and reactivation and the clinical management of NPC patients with HBV infections are lacking. This study was aimed at clarifying the risk of reactivation for NPC patients on different regimens while providing evidence concerning HBV screening and management in an endemic area. METHODS With the NPC database from an established big-data intelligence platform at Sun Yat-Sen University Cancer Center in China, NPC patients who were diagnosed between 2008 and 2016 and underwent HBV screening and regular monitoring of liver enzymes and HBV deoxyribonucleic acid (DNA) were analyzed. RESULTS Among the 46,919 patients identified, the HBV screening rate was 24.8% (11,616 of 46,919). Among the screened patients with an HBV infection, regular monitoring of liver enzymes and HBV DNA occurred for 563 patients. The incidence of HBV reactivation and HBV-related hepatitis was 9.1% (51 of 563) and 2.5% (14 of 563), respectively. The reactivation risk varied for different treatments and regimens and ranged from 0.0% to 21.4%. Detectable baseline HBV DNA (odds ratio [OR], 2.93; P < .01), the presence of liver metastasis at diagnosis (OR, 7.19; P < .01), and antiviral prophylaxis (OR, 0.29; P < .01) were significantly associated with reactivation. CONCLUSIONS In NPC patients with chronic HBV infections on high-risk regimens, the reactivation risk is similar to or exceeds the risk associated with other immunosuppressive therapies for which screening and prophylaxis are recommended. Our findings, therefore, support HBV screening and prophylaxis for these patients, whereas regular monitoring might be appropriate for patients with resolved HBV infections or those receiving low-risk regimens.

Abstract
Purpose Conditional survival (CS) provides important information on survival for a period of time after diagnosis. Currently, information on CS patterns of patients with nasopharyngeal carcinoma (NPC) is lacking. We aimed to analyze survival rate over time and estimate CS for NPC patients using a national population-based registry. Materials and Methods Patients diagnosed with NPC between 1973 and 2007 with at least 5-year follow-up were identified from the Surveillance Epidemiology End Results registry. Traditional survival rates and crude CS estimateswere calculated using Kaplan-Meier analysis. Risk-adjusted survival curves were plotted from the proportional hazards model using the correct group prognosis method. Results registry. Traditional survival rates and crude CS estimateswere calculated using Kaplan-Meier analysis. Risk-adjusted survival curves were plotted from the proportional hazards model using the correct group prognosis method. Results For 7,713 patients analyzed, adjusted baseline 5-year overall survival improved significantly from 36.0% in patients diagnosed in 1973-1979, 41.7% in 1980-1989, 46.6% in 1990-1999, to 54.7% in 2000-2007 (p < 0.01). CS analysis demonstrated that for every additional year survived, adjusted probability of surviving the next 5 years increased from 66.7% (localized), 54.0% (regional), and 35.3% (distant) at the time of diagnosis, to 83.7% (localized), 75.0% (regional), and 62.2% (distant) for patients who had survived 5 years. Adjusted 5-year CS differed among age, sex, tumor histology, ethnicity, and stage subgroups initially, but converged with time. Conclusion Treatment outcomes of NPC patients have greatly improved over the decades. Increases in CS become more prominent in patients with distant disease than in those with localized or regional disease as patients survive longer. CS provides more dynamic prognostic information for patients who have survived a period of time after diagnosis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kegan Liyan oral liquid (KGLY), a Chinese prescription modified from classic formulas Yin-Qiao-San (from TCM classic Wenbing Tiaobian) and Shen-Jie-San (first mentioned in Shanghan Wenyi Tiaobian), has been reported to exert heat-clearing and detoxifying effects and used extensively for the treatment of severe pulmonary diseases in clinics including influenza, cough and pneumonia. AIM OF THIS STUDY The purpose of this study was to investigate the protective effect of KGLY on lipopolysaccharide (LPS) induced acute lung injury (ALI) in mice and to illuminate the underlying mechanisms. MATERIALS AND METHODS Mice were orally administrated with KGLY (50, 100 and 150mg/kg) before intratracheal instillation of LPS. 24h post LPS challenge, lung tissues and the bronchoalveolar lavage fluid (BALF) were collected for lung wet/dry (W/D) weight ratio, histopathological examinations and biochemical analyses. The cell counts, protein concentration, interleukin-1β (IL-1β), interleukin-6 (IL-6), necrosis factor-α (TNF-α), macrophage inflammatory protein-2 (MIP-2) in BALF, superoxide dismutase (SOD), glutathione (GSH), myeloperoxidase (MPO) and malondialdehyde (MDA) levels were detected. Meanwhile, the activation of toll-like receptor 4 (TLR4), nuclear factor kappa B (NF-κB), as well as matrix metalloproteinases 9 (MMP-9) were determined by western blot assay. RESULTS KGLY significantly prolonged mice survival time and ameliorated LPS-induced edema, thickening of alveolar septa and inflammatory cell infiltration in a dose-dependent manner. Additionally, KGLY markedly attenuated LPS-induced acute pulmonary inflammation via decreasing the expressions of cytokines and chemokines (IL-1β, IL-6, TNF-α, and MIP-2), enhanced the activities of anti-oxidative indicators (SOD and GSH), suppressed the levels of MPO and MDA, and down-regulated the expressions of TLR4, NF-κB and MMP9. CONCLUSIONS The results suggested that the relieving effect of KGLY against LPS-induced ALI might be partially due to suppression of oxidative stress and inflammatory response, inhibition of TLR4-mediated NF-κB activation, and down-regulation of MMP9 expression, indicating it may be a potential therapeutic agent for ALI.

Abstract
The aim of this study was to investigate the influence of Se deficiency on the transcription of inflammatory factors and selenoprotein genes in the kidneys of broiler chicks. One hundred fifty 1-day-old broiler chicks were randomly assigned to two groups fed with either a low-Se diet (L group, 0.033 mg/kg Se) or an adequate Se diet (C group, 0.2 mg/kg Se). The levels of uric acid (UA) and creatinine (Cr) in the serum and the mRNA levels of 6 inflammatory factors and 25 selenoprotein genes in the kidneys were measured as the clinical signs of Se deficiency occurred at 20 days old. The results indicated that the contents of UA and Cr in the serum increased in L group (p < 0.05), and the mRNA levels of the inflammatory factors (NF-κB, iNOS, COX-2, and TNF-α) increased in L group (p < 0.05). Meanwhile, the mRNA levels of PTGEs and HO-1 were not changed. In addition, 25 selenoprotein transcripts displayed ubiquitous expression in the kidneys of the chicks. The mRNA levels of 14 selenoprotein genes (Dio1, Dio2, GPx3, Sepp1, SelH, SelI, SelK, Sepn1, SelO, SelW, Sep15, SelT, SelU, and SelS) decreased, and 9 selenoprotein genes (GPx1, GPx2, GPx4, SelPb, Txnrd1, Txnrd2, Txnrd3, SPS2, and SelM) increased in L group (p < 0.05), but the Dio3 and Sepx1 mRNA levels did not change. The results indicated that Se deficiency resulted in kidney dysfunction, activation of the NF-κB pathway, and a change in selenoprotein gene expression. The changes of inflammatory factor and selenoprotein gene expression levels were directly related to the abnormal renal functions induced by Se deficiency.

Abstract
The objectives of this study were to determine the molecular weight of condensed tannins (CT) extracted from mangosteen (Garcinia mangostana L) peel, its protein binding affinity and effects on fermentation parameters including total gas, methane (CH4) and volatile fatty acids (VFA) production. The average molecular weight (Mw) of the purified CT was 2,081 Da with a protein binding affinity of 0.69 (the amount needed to bind half the maximum bovine serum albumin). In vitro gas production declined by 0.409, 0.121, and 0.311, respectively, while CH4 production decreased by 0.211, 0.353, and 0.549, respectively, with addition of 10, 20, and 30 mg CT/500 mg dry matter (DM) compared to the control (p<0.05). The effects of CT from mangosteen-peel on in vitro DM degradability (IVDMD) and in vitro N degradability was negative and linear (p<0.01). Total VFA, concentrations of acetic, propionic, butyric and isovaleric acids decreased linearly with increasing amount of CT. The aforementioned results show that protein binding affinity of CT from mangosteen-peel is lower than those reported for Leucaena forages, however, the former has stronger negative effect on IVDMD. Therefore, the use of mangosteen-peel as protein source and CH4 mitigating agent in ruminant feed requires further investigations.

Abstract
AIM: To investigate the relationship between cholecystectomy and fatty liver disease (FLD) in a Chinese population.
METHODS: A total of 32428 subjects who had voluntarily undergone annual health checkups in the Second Affiliated Hospital of Nanjing Medical University from January 2011 to May 2013 were included in this study. Basic data collection, physical examination, laboratory examination, and abdominal ultrasound examination were performed.
RESULTS: Subjects undergoing cholecystectomy were associated with greater age, female sex, higher body mass index, and higher levels of systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol, and triglycerides. However, no significant differences were found in high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, albumin, and serum uric acid. The overall prevalence of FLD diagnosed by ultrasonography was high at 38.4%. The prevalence of FLD was significantly higher for subjects who had undergone cholecystectomy (46.9%) than those who had not undergone cholecystectomy (38.1%; χ2 test, P < 0.001). Cholecystectomy was positively associated with FLD (OR = 1.433, 95%CI: 1.259-1.631). However, after adjusting for possible factors associated with FLD, multivariate regression analysis showed that the association between cholecystectomy and FLD was not statistically significant (OR = 1.096; 95%CI: 0.939-1.279).
CONCLUSION: According to our study results, cholecystectomy may not be a significant risk factor for FLD.

Abstract
OBJECTIVE To study the biological characteristics of cypermethrin-resistance strain and -susceptible strain of Aedes albopictus under different controlled temperatures in the laboratory. METHODS The two strains were raised at three different temperatures, 20, 25 degrees C and 28 degrees C respectively, and the biological characteristics of the two mosquito strains, such as reproduction, development and life expectancy, were observed and recorded in the laboratory. RESULTS The life expectancy of both strains became shorter as the temperature raised, and the resistant strain(69.37% ± 0.01%, 77.04% ± 0.07%) lived shorter than the susceptible strain(85.24% ± 0.03%, 88.23% ± 0.05%)in average. Under 25 degrees C, the hatching rate of resistant strain decreased by 25.88%, and the pupation rate decreased by 11.18%. In the three temperatures, all the life expectancy expanded as the temperature went up, the periods for the susceptible strain were 19.75 ± 0.10, 23.65 ± 0.07 d and 25.08 ± 0.08 d under 28, 25 degrees C and 20 degrees C. While life expectancy for the resistant strain decreased to 17.21 ± 0.09, 20.95 ± 0.09, 22.58 ± 0.10 d. Under the same temperature, the development timing of the resistance strain was longer than that of the susceptible strain, and the period was the longest under 28 degrees C (156.2 h, 137.1 h). In the three temperatures, all the development periods expanded as the temperature went up, the susceptible and resistant larvae developed 137.1 d and 163.3 d, 247.7 d and 156.2 d, 182.3 d and 263.2 d under 28, 25 degrees C and 20 degrees C. The differences show statistic significance (P < 0.05). CONCLUSION The resistance of A. albopictus to cypermethrin results in the decrease of adaptability to the environment change and the disadvantage of reproduction at different temperatures.

Abstract
ITS2 sequence was used as a barcode to identify herbal tea ingredient Plumeria rubra and its adulterants. Genomic DNAs from forty eight samples were extracted, the ITS2 sequences were amplified and sequenced bi-direstionlly, and then assembled and obtained using CodonCode Aligner. The sequences were aligned using ClustalW, the genetic distances were computed by kimura 2-parameter (K2P) model and the Neighbor-joining (NJ) phylogenetic trees were constructed using MEGA5.0. Results showed that the length of ITS2 sequence of P. rubra were 244 bp. The intra-specific genetic distances (0-0. 016 6) were much smaller than inter-specific ones between P. rubra and its adulterants(0.320 8-0.650 4). The NJ tree indicated that P. rubra and its adulterants could be distinguished clearly. Therefore, Using ITS2 barcode can accurately andeffectively distinguish herbal tea ingredient P. rubra from its adulterants, which providesa new molecular method to identify P. rubra and ensure its safety in use.

Abstract
Volatile oil components and the contents and types of amino acid in spica of Prunella vulgaris were analysed by GC-MS and amino acid analyzer. Esters, fatty acids, aromatic hydrocarbon, ketone and several alcohol compounds were identified by mass spectrum comparison. In these ingredients, beta-ionone smelled aroma of cedar, raspberry, nerolidol showed weak sweet soft orange blossom flavor, neroli tasted sweet and fresh, nerolidol tasted sweet with light aroma of wood, hexadecanal showed a weak aroma of flowers and wax, alpha-sinensal had rich and fresh sweet orange flavor. To some extent, these types of aromatic substances can affect the taste of herbal tea or decoction made of Spica Prunellae. Among amino acids detected, natural amino acids accounted for a larger proportion, and those natural amino acids showed bitterness, slight bitterness, sourness (freshness), sweetness, slight sweetness, sourness (slight freshness). The results indicated that bitter and slightly bitter amino acids have the greatest impacts on the sense of Spica Prunellae.

Abstract
In the present study, we investigated the anticancer effects of sodium butyrate (NaBu) on hepatocellular carcinoma (HCC) cells in vitro. As a histone deacetylase (HDAC) inhibitor, NaBu upregulated Ac-H3 and inhibited HDAC4 protein expression in a time- and dose-dependent manner. MTT assays showed that treatment with NaBu at high concentrations significantly inhibited the growth of various HCC cells. Exposure to NaBu for 24 h induced cell cycle arrest in the SMMC-7721 and HepG2 cells. NaBu also induced the apoptosis of SMMC‑7721 cells. The expression levels of cell cycle- and apoptosis-related proteins were further investigated by western blot analysis using specific antibodies. The results provided a possible mechanism responsible for the inhibitory effects of NaBu on the growth of HCC cells. To further analyze the role of NaBu in cell migration, wound healing and Transwell assays were performed, indicating that NaBu significantly inhibits cell migration/invasion in HCC cells. Transforming growth factor-β1 (TGF-β1)-induced epithelial to mesenchymal transition (EMT) has been associated with tumor cell migration and invasion. The EMT markers, E-cadherin, vimentin and N-cadherin, were regulated by TGF-β1, while NaBu inhibited this process in which HDAC4 and matrix metalloproteinase (MMP)7 may be involved. Based on our findings, we propose that NaBu may be useful as an anticancer drug for HCC therapy.

Abstract
AIM: To investigate the influence of loss of Smad4 expression on TGF-β1-induced epithelial-mesenchymal transition in the human hepatocellular carcinoma cell line SMMC-7721.
METHODS: The influence of loss of Smad4 expression on the expression of β-catenin and Vimentin mRNAs and proteins was evaluated by RT-PCR and Western blot. Immunofluorescence was used to analyze the location and fluorescence intensity of Smad4, β-catenin, Vimentin in non-transfected SMMC-7721 cells and those transfected with Smad-specific siRNAs (RNAi-Smad4-2 and RNAi-Smad4-12) or unspecific siRNA (RNAi-NC).
RESULTS: Compared to non-transfected SMMC-7721 cells and those tranfected with RNAi-NC, the expression of β-catenin mRNA and protein remarkably increased in SMMC-7721 cells transfected with RNAi-Smad4-2 or RNAi-Smad4-12 (all P < 0.05). Loss of Smad4 expression promoted β-catenin nuclear translocation. Immunofluorescence assay revealed that β-catenin fluorescence was located in the nuclei of non-transfected SMMC-7721 cells and those tranfected with RNAi-NC, but in the cytoplasm of SMMC-7721 cells transfected with RNAi-Smad4-2 or RNAi-Smad4-12. On the other hand, loss of Smad4 expression down-regulated Vimentin protein expression (P < 0.05) and cytoplasmic fluorescence intensity, but had no significant impact on Vimentin mRNA expression in SMMC-7721 cells and those transfected with different siRNAs.
CONCLUSION: Loss of Smad4 expression regulates β-catenin and Vimentin and therefore plays an important role in inhibiting epithelial-mesenchymal transition in SMMC-7721 cells.

Abstract
Epithelial-mesenchymal transition (EMT) refers to the process by which cells transit from epithelial phenotype to mesenchymal phenotype. EMT is critical for tumor invasion and metastasis, however, the underlying mechanism is little known so far. It has been known that complex signaling pathways are involved in this process. MicroRNAs also play an important role in tumors via many EMT-related signaling pathways. Numerous studies have established that there is a link between EMT-related signaling pathways and microRNAs in tumors. This review focuses on the action mechanism of various EMT-related signaling pathways and their relationship with microRNAs in tumors.

Abstract
Peutz-Jeghers syndrome (PJS) is an autosomal-dominant inherited disorder characterized by mucocutaneous pigmentation, hamartomatous polyposis of the gastrointestinal tract, and an increased risk for the development of both gastrointestinal and extraintestinal malignancies. Germline mutation of the STK11 gene, which encodes a serine-threonine kinase, is responsible for PJS. We collected blood samples from a Chinese PJS family consisting of a total of four individuals (one male and three females) including one PJS patient. The whole coding region of STK11 was amplified by polymerase chain reaction and products analyzed by direct sequencing. Molecular analysis of the STK11 gene in this case of PJS revealed a substitution of thymine 217 for adenine (C.217T > A) in exon 1, resulting in a change of codon 73 from cysteine to serine (C73S). The point mutation was not found in normal individuals in this PJS family or in 100 control individuals. The results presented here enlarge the spectrum of mutations of the STK11 gene by identifying a de novo mutation in a PJS patient and further support the hypothesis that STK11 mutations are disease-causing mutations for PJS.

Abstract
OBJECTIVE To compare the aqueous humor concentration of levofloxacin 0.5%, gatifloxacin 0.3% and levofloxacin 0.3% ophthalmic solution after topical dosing in human eyes. METHODS A randomized, double-blind and parallel study was conducted. Senile cataract patients (150 eyes in 150 cases) receiving phacoemulsification in eye center affiliated second hospital of Zhejiang university were randomized into three groups: levofloxacin 0.5%, 50 eyes;gatifloxacin 0.3%, 50 eyes and levofloxacin 0.3%, 50 eyes. Each group was randomized into five sub-groups, with 10 eyes in each sub-group. Each group received either levofloxacin 0.5% or topical gatifloxacin 0.3% or levofloxacin 0.3% preoperatively. One drop of antibiotic was administered every 15 minutes for 4 doses. More than 100 microl aqueous samples were obtained from different sub-groups during surgery, 15.0, 30.0, 60.0, 120.0 and 180.0 min after the last drop, respectively. Then 100 microl aqueous samples were put into test tube by sample injector accurately. Concentration of the antimicrobial agents was determined by the HPLC (high pressure liquid chromatography). Variance analysis was performed to detect differences among the antibiotic treatment groups. The differences between two groups were assumed by t-test. RESULTS Humor concentration of levofloxacin 0.5% (1.61 +/- 0.48), (2.41 +/- 0.80), (2.93 +/- 0.50), (2.56 +/- 0.63), (1.87 +/- 0.88) mg/L was significantly higher than that of gatifloxacin 0.3% (0.70 +/- 0.18), (1.29 +/- 0.54), (1.59 +/- 0.67), (1.41 +/- 0.50), (1.13 +/- 0.28) mg/L and levofloxacin 0.3% (0.55 +/- 0.39), (1.15 +/- 0.42), (1.38 +/- 0.49), (1.02 +/- 0.33), (0.55 +/- 0.31) mg/L at the same period after the last drop (F = 23.64, 12.82, 21.13, 25.00, 12.22;P < 0.05). CONCLUSION Topically applied levofloxacin 0.5% had the higher aqueous humor drug level than gatifloxacin 0.3% and levofloxacin 0.3%.

Abstract
Transforming growth factor beta (TGF-β) is a ubiquitous and essential regulator of cellular and physiologic processes including proliferation, differentiation, migration, cell survival, angiogenesis and immunosurveillance. The tumor suppressor gene Smad4 (DPC4) is the central intracellular mediator of transforming growth factor-β-Smad(TGF-β-Smad) signaling, which is a key pathway in cancer invasion and metastasis. This review focuses on the mechanisms whereby the Smads are modified and regulated, and summarizes current views on the role of Smad4 in tumorigenesis, with emphasis on cancer invasion and metastasis.

Abstract
PURPOSE To analyse the in vitro adherence of Staphylococcus epidermidis to the 2-methacryloyl oxyethyl phosphorylcholine (MPC)-modified silicone intraocular lens (IOL). METHODS The test IOLs were modified by using an air plasma treatment to bind MPC to the surface. The control IOLs were not modified. Chemical changes on the IOL surface were analysed by X-ray photoelectron spectroscopy (XPS) to confirm the covalent binding of MPC. IOL hydrophilicity was determined by measuring the water contact angle. Two different techniques, direct counting of viable adherent bacteria released by sonication, and scanning electron microscopy (SEM), were used to observe and compare the adherence of S. epidermidis to the IOLs after 1- and 18-h incubation. RESULTS XPS analysis confirmed that the test IOLs were surface-modified with MPC. The hydrophilicity of the IOLs was improved by surface modification, and the MPC-modified IOLs exhibited significantly reduced adhesion of S. epidermidis (P = 0.002) after an incubation period of 1 h. The SEM results showed that the MPC modification also suppressed the accumulation of bacteria and biofilm production after 18 h incubation. CONCLUSIONS MPC-modified hydrophilic silicone IOLs reduce bacterial adherence and colonization, and thus may help reduce the incidence of postoperative endophthalmitis.

Abstract
Polyacrylonitrile modified with N-vinyl-2-pyrrolidone (NVP) shows good hemocompatibility. This work, which aims to evaluate the cytocompatibility of membranes fabricated from poly(acrylonitrile-co-N-vinyl-2-pyrrolidone) (PANCNVP), studied the adhesion of macrophages and endothelial cell (EC) cultures. It was found that PANCNVP membranes with higher NVP content decreased the adhesion of both macrophages and ECs. Compared with polyacrylonitrile and tissue culture polystyrene control, however, these PANCNVP membranes promoted the proliferation of ECs. Furthermore, the viability of ECs cultured on the PANCNVP membrane surfaces was also relatively competitive. Both static and dynamic water contact angle measurements were conducted to explain the nature of cell adhesion to the PANCNVP membranes. On the basis of these results and the phenomena of water swelling and water states reported previously, it was presumed that the coexistence of large amounts of bound water and free water induced by NVP moieties are responsible for the lower adhesion and better function of cells adhering to the PANCNVP membranes.

Abstract
The wetting of polydimethylsiloxane oil drops on the surfaces of anionic surfactant sodium dodecylsulfate solutions is studied systematically by changing the bulk surfactant concentration. The wetting state changes from complete wetting to pseudopartial wetting at 0.3 cmc (critical micelle concentration) surfactant concentration and there is a reentrant transition back to complete wetting at 1.4 cmc. The measured free energy is consistent with the prediction of the wetting theory. The interaction potential minimum of the two surfaces of the oil film disappears at the reentrant point, which is speculated to be an effect of micelle formation in the solution.

Abstract
To improve the surface biocompatibility of the silicone intraocular lens (IOL), 2-methacryloyloxyethyl phosphorylcholine (MPC) was tethered onto the IOL through air plasma treatment. Chemical changes on the IOL surface were characterized by X-ray photoelectron spectroscopy (XPS) to confirm the covalent binding of MPC. Morphologies of the IOL surfaces were observed by scanning electron microscopy (SEM) to optimize the plasma treatment process. The hydrophilicity and biocompatibility of the control and modified IOLs were compared by the measurements of water contact angle, platelet adhesion, macrophage cell culture, and lens epithelial cell (LEC) attachment. It was found that, after the tethering of MPC, the hydrophilicity of the IOL can be improved significantly and permanently, and the platelet, macrophage, and LEC adhesion on the IOL surface are obviously suppressed, which indicated the enhancement of surface biocompatibility.
