Abstract
SCOPE 3,5-Dihydroxy-4-methoxybenzyl alcohol (DHMBA) is found in oyster extracts in recent years and is reported to have antioxidant activity. Although it has been reported to be protective in various models of oxidative stress, the therapeutic effect of DHMBA on neurological damage caused by aging remains to be demonstrated. METHODS AND RESULTS The present study investigates the potential functions of DHMBA in brain of old C57BL/6J mice and aging cell model. Administration of DHMBA improves working memory, reduces anxiety behavior, decreases the expression levels of cell cycle proteins, cycin-dependent kinase inhibitor 1(P21) and peptidase inhibitor 16(P16) and inhibits neuronal loss in old mice. The data obtained from the aging cell model are consistent with those from the old mice. The interaction between DHMBA and Kelch-like ECH-associated protein 1 (Keap1) is predicted by molecular docking assay, and then it is verified by co-immunopricipitation (CoIP) that factor red lineage 2-related factor 2 (Nrf2)-Keap1 protein-protein interaction is inhibited by DHMBA. Protein levels of Nrf2 and its target genes, such as glutathione peroxidase 4(GPX4) and heme oxygenase 1 (HO-1), are detected in old mice and aging cell model. CONCLUSION This study provides new evidence that explores the antioxidant mechanism of DHMBA and implies a potential role of DHMBA on antiaging in brain.

Abstract
Three new heteroleptic Ru complexes, CYC-B22, CYC-B23C, and CYC-B23T, were prepared as sensitizers for coadsorbent-free, panchromatic, and efficient dye-sensitized solar cells. They are simultaneously functionalized with highly conjugated anchoring and ancillary ligands to explore the electronic and steric effects on their photovoltaic characteristics. The coadsorbent-free device based on CYC-B22 achieved the best power conversion efficiency (PCE) of 8.63% and a panchromatic response extending to 850 nm. The two stereoisomers, CYC-B23C and CYC-B23T coordinated with an unsymmetrical anchoring ligand, display similar absorption properties and the same driving forces for electron injection as well as dye regeneration. Nevertheless, the devices show not only the remarkably distinct PCE (6.64% vs 8.38%) but also discernible stability. The molecular simulation for the two stereoisomers adsorbed on TiO2 clarifies the distinguishable distances (16.9 Å vs 19.0 Å) between the sulfur atoms in the NCS ligands and the surface of the TiO2, dominating the charge recombination dynamics and iodine binding and therefore the PCE and stability of the devices. This study on the steric effects caused by the highly conjugated and unsymmetrical anchoring ligand on the adsorption geometry and photovoltaic performance of the dyes paves a new way for advancing the molecular design of polypyridyl metal complex sensitizers.

Abstract
This study was to determine the effects of the mixture of glycerol monolaurate and cinnamaldehyde (GCM) supplementation on the intestinal morphology, immunity, antioxidant status and cecal microbiota of laying hens. A total of 1,120 healthy laying hens (Jingfen-1 strain) at the age of 14 wk were randomly divided into 4 groups with 10 replicates of 28 layers in each and layers were fed diets containing 0 (control group), or 250, 500, and 1,000 mg/kg GCM for 12 wk. The results showed that dietary supplementation with GCM significantly increased intestinal villus height and villus height/crypt depth, duodenal villus area, total superoxide disumutase activities in the liver and jejunum, jejunal glutathione peroxidase activities while decreased duodenal and jejunal crypt depth, hydrogen peroxide content in the liver and jejunal malondialdehyde content of laying hens aging 28 wk (P < 0.05). Meanwhile, GCM addition significantly increased serum immunoglobulin A and immunoglobulin M concentration of layers at the age of 20, 24, and 28 wk (P < 0.05). Moreover, it was observed in the 16S rRNA sequencing that the addition of GCM elevated the abundance and diversity of gut microbiota in laying hens. The predominant bacteria from each group were Bacteroidota and Firmicutes at the phylum level and Bacteroides and Lactobacillus were the dominant genera. The composition and structure of cecal microflora were changed by the addition of GCM to the diet of laying hens. In conclusion, the addition of GCM (500-1,000 mg/kg diet) can improve intestinal morphology, immune function, intestinal and liver antioxidant status and intestinal flora of laying hens, thereby improving intestinal digestion and absorption capacity. These findings provide a new way to further explore the mechanism of GCM improving intestinal health.

Abstract
With the rising need for accessible cervical cancer screening, self-sampling methods offer a promising alternative to traditional physician-led sampling. This study aims to evaluate the efficacy of the HygeiaTouch Self Sampling Kit for Women in detecting human papillomavirus (HPV) types and predicting cervical lesions. We studied the concordance in identifying high-risk HPV (hrHPV) types between samples collected by physicians and those self-collected by women using a self-sampling kit for validation. Women aged 21-65, fitting into specific categories based on their cervical health history were eligible. Cohen's kappa coefficient to gauge concordance between the two specimen types and relative accuracy metrics in identifying cervical intraepithelial neoplasia (CIN) were also calculated, with physician-sampled specimens serving as a reference. A total of 1210 participants from three institutes were involved. The self-sampling kit closely matched the physician-led method in terms of collecting valid specimens (100% vs. 100%), identifying hrHPV types (kappa: 0.75, 95% confidence interval [95% CI]: 0.72-0.79; agreement: 87.7%, 95% CI: 85.8-89.6) and predicting CIN grade 2 or worse (CIN2+) (relative sensitivity: 0.949, relative accuracy: 0.959). Kappa values varied between 0.71 and 0.83 for different hrHPV types and combinations, with an overall value 0.75 (95% CI: 0.72-0.79) signifying robust compatibility between the two methods. Our study underscores the potential of the HygeiaTouch Self Sampling Kit as a reliable, efficient, and user-friendly alternative to traditional sampling methods. This suggests that self-sampling could be pivotal in expanding cervical cancer screening accessibility and enhancing detection rates.

Abstract
BACKGROUND Surgical treatment is playing an increasingly important role in the management of nasopharyngeal carcinoma (NPC). This consensus focuses on the indications for optimal surgery, and surgical methods in the whole process of treatment for NPC to provide a useful reference to assist these difficult clinical decisions. METHODOLOGY A thorough review of available literature on NPC and surgery was conducted by the Association for the prevention and treatment of nasopharyngeal carcinoma in China, international exchange and promotion Association for medicine and healthcare, and the Committee on nasopharyngeal cancer of Guangdong provincial anticancer association. A set of questions and a preliminary draft guideline was circulated to a panel of 1096 experienced specialists on this disease for voting on controversial areas and comments. A refined second proposal, based on a summary of the initial voting and different opinions expressed, was recirculated to the experts in two authoritative medical science and technology academic groups in the prevention and treatment of NPC in China for review and reconsideration. RESULTS The initial round of questions showed variations in clinical practice even among similar specialists, reflecting the lack of high-quality supporting data and resulting difficulties in formulating clinical decisions. Through exchange of comments and iterative revisions, recommendations with high-to-moderate agreement were formulated on general treatment strategies and details of surgery, including indications and surgical approaches. CONCLUSION By standardizing the surgical indications and practice, we hope not only to improve the surgical outcomes, but also to highlight the key directions of future clinical research in the surgical management of NPC.

Abstract
Objective: To summarize the experience of facial nerve(FN) preservation in microsurgical treatment of vestibular schwannoma (VS) resection via suboccipital retrosigmoid approach and to analyze the influencing factors of facial function prognosis in short-term and long-term period. Methods: Patients with VS who underwent microsurgery via suboccipital retrosigmoid approach by the skull base surgery team in Huashan Hospital from January 2013 to February 2018 were enrolled. A total of 308 patients were included in this study, including 132 males and 176 females. The average age was 47.9 year-old (Range: 17-79 year-old). The patient's clinical data and FN function prognosis were recorded. Univariate and multivariate analysis by SPSS 23.0 statistical software were performed to evaluate the factors affecting facial function prognosis and its recovery. Results: Gross total resection was achieved in 304 cases, and subtotal resection was in 4 cases. The facial nerve preservation rate anatomically was 99.4%. The facial nerve of 2 cases was thin due to large tumor compression and severed, and a one-stage reconstruction was performed during surgery.Of the 308 patients, 300 cases were successfully followed up, and 8 cases were lost to follow-up. The mean follow-up time was 52 months. In short-term (2 weeks after surgery), satisfactory facial nerve function (House-Brackmann (H-B) grade Ⅰ-Ⅱ) was achieved in 96 cases, and 212 cases were unsatisfactory function (H-B grade Ⅲ-Ⅵ). After 1 year, 198 were satisfactory function and 97 were unsatisfactory. After 3 years, 219 were satisfactory function and 75 were unsatisfactory. Five years later, 155 were satisfactory function and 34 were unsatisfactory. According to the results of logistic regression analysis, the impact factors of FN function in short-term were tumor size (P=0.011) and stimulation threshold (ST) of EMG monitoring (P<0.001). The impact factors in long-term were tumor size (P=0.005), ST of EMG monitoring (P=0.005) and FN rehabilitation training. Conclusions: Tumor diameter is an independent factor related to FN function, and the larger the tumor, the worse the postoperative FN function. The ST of EMG (ST≤0.05 mA) can predict short-term and long-term FN function. The systematic facial rehabilitation training can effectively promote the recovery of FN after surgery.

Abstract
Objective: To establish occupational exposure limits for glyphosate in workplace air. Methods: In November 2014, by searching the documents of the United States Environmental Protection Agency (EPA) on glyphosate toxicity, the toxicity data and clinical symptoms of glyphosate toxicity were collected through various literature databases, and the target organs of glyphosate toxicity were determined. A total of 5 representative production enterprises in Jiangsu Province and Shandong Province were selected for field investigation. A total of 968 people were selected as the study subjects, including 526 workers exposed to glyphosate as the contact group, and 442 off-site (such as financial, administrative, etc.) workers with enterprises as the control group. Health examination was carried out in the exposure group and the control group to observe the damage of target organs of workers with different exposure concentrations and determine the occupational exposure limit. Results: The main target organs of glyphosate are liver and kidney and its effect on cholinesterase activity. The time-weighted average concentration (TWA) of glyphosate exposure in the exposure group was <0.03~48.91 mg/m(3), and there were statistically significant differences in liver and renal function between the exposure group and the control group (P<0.05). When the concentration of glyphosate in the air was higher than 5 mg/m3, there was a statistically significant difference in the abnormal rate of renal function between the exposure group and the control group (P<0.05) . Conclusion: The study sets the occupational exposure limit of glyphosate as 5 mg/m(3). The safety of this standard conforms to the relevant requirements of toxicology and occupational disease epidemiology, and also conforms to the existing economic and technological level in my country, and is highly feasible.

Abstract
Objective: To investigate the prognoses of advanced (T3-T4) sinonasal malignancies (SNM). Methods: The clinical data of 229 patients with advanced (T3-4) SNM who underwent surgical treatments in the First Affiliated Hospital of Sun Yat-sen University from 2000 to 2018 were retrospectively analyzed, including 162 males and 67 females, aged (46.8±18.5) years old. Among them, 167 cases received endoscopic surgery alone, 30 cases received assisted incision endoscopic surgery, and 32 cases received open surgery. The Kaplan-Meier method was used to estimate the 3-year and 5-year overall survival (OS) and event-free survival (EFS). Univariate and multivariate Cox regression analyses were performed to explore significant prognostic factors. Results: The 3-year and 5-year OS were respectively 69.7% and 64.0%. The median OS time was 43 months. The 3-year and 5-year EFS were respectively 57.8% and 47.4%. The median EFS time was 34 months. The 5-year OS of the patients with epithelial-derived tumors was better than that of the patients with mesenchymal-derived tumors and malignant melanoma (5-year OS was respectively 72.3%, 47.8% and 30.0%, χ2=36.01, P<0.001). Patients with microscopically margin-negative resection (R0 resection) had the best prognosis, followed by macroscopically margin-negative resection (R1 resection), and debulking surgery was the worst (5-year OS was respectively 78.4%, 55.1% and 37.4%, χ2=24.63, P<0.001). There was no significant difference in 5-year OS between the endoscopic surgery group and the open surgery group (65.8% vs. 53.4%, χ2=2.66, P=0.102). Older patients had worse OS (HR=1.02, P=0.011) and EFS (HR=1.01, P=0.027). Patients receiving adjuvant therapy had a lower risk of death (HR=0.62, P=0.038). Patients with a history of nasal radiotherapy had a higher risk of recurrence (HR=2.48, P=0.002) and a higher risk of death (HR=2.03, P=0.020). Conclusion: For patients with advanced SNM, the efficacy of endoscopic surgery can be comparable to that of open surgery when presence of safe surgical margins, and a treatment plan based on transnasal endoscopic surgery as the main comprehensive treatment is recommended.

Abstract
Objective: To analyze HIV/AIDS surveillance data in men who have sex with men (MSM) aged from 15 to 24 years in Fuzhou and understand the HIV infection status in MSM and related factors. Methods: From 2016 to 2021, MSM aged 15-24 years who had oral or anal sex with men in the past 6 months were recruited through internet, and their demographic and behavioral characteristics, HIV antibody positive rate and risk factors were analyzed. Results: From 2016 to 2021, a total of 4 234 MSM aged 15-24 years were surveyed. The proportion of MSM from other provinces increased from 13.00% (85/654) to 23.42% (163/696) (trend χ2=60.23, P<0.001); and the proportion of MSM seeking male partners through internet increased from 93.27% (610/654) to 99.71% (694/696) (trend χ2=65.20, P<0.001); In the last anal sex in the past 6 months, the proportion of MSM using condom decreased from 88.16% (484/549) to 74.11% (415/560) (trend χ2=32.32, P<0.001); and in the past 6 months, the proportion of MSM using condom at each anal sex decreased from 65.76% (361/549) to 55.54% (311/560) (trend χ2 =6.82, P<0.001); The proportion of MSM with HIV antibody testing increased from 5.66% (37/654) to 25.29% (176/696) (trend χ2=98.51, P<0.001). The cumulative HIV antibody positive rate in the MSM was 3.64% (154/4 234), and there was no significant difference in annual HIV antibody positive rate in the MSM (trend χ2=0.50, P=0.453). The HIV antibody positive rate in the MSM with education level of junior high school or below and the MSM living in Fuzhou for 1-2 years showed an upward trend (P<0.05). The results of multivariate logistic regression analysis showed that the risk for HIV infection in the MSM with education level of high school or technical secondary school was 0.54 times higher than that in those with education level of junior high school or below (95%CI: 0.30-0.99), and the risk for HIV infection in the MSM with education level of junior college or below was 0.29 times higher than that in those with education level of junior high school or below (95%CI: 0.17-0.51). The risk for HIV infection in the MSM who lived in Fuzhou for 1-2 years was 0.35 times higher than that in those who lived in Fuzhou for less than 1 year (95%CI: 0.16-0.74), the risk for HIV infection in the MSM who lived in Fuzhou for more than two years was 0.58 times higher than that in those who lived in Fuzhou for less than 1 year (95%CI: 0.37-0.91). The number of MSM using condoms at each anal sex was 0.18 times higher than that in the those never using condoms (95%CI: 0.08-0.42), and the number of the MSM who didn't suffered from sexually transmitted diseases was 0.25 times higher than that in those who suffered from sexually transmitted diseases (95%CI: 0.13-0.50). Conclusions: The MSM aged 15-24 years in Fuzhou have higher risk for HIV infection, and internet based intervention should be strengthened in adolescent MSM without permanent residence and with low education level.

Abstract
Objective: To perform a cost-effectiveness analysis of endoscopic surgery versus intensity-modulated radiotherapy in the treatment of locally recurrent nasopharyngeal carcinoma (rNPC) from a health-economic perspective. Methods: From September 30, 2011 to January 16, 2017, a total of 200 patients were enrolled in the First Affiliated Hospital of Sun Yat-sen University, the First People's Hospital of Foshan, and Sun Yat-sen University Cancer Center. These patients were diagnosed as locally rT1-rT3 stage rNPC and were randomly assigned 1︰1 to the endoscopic surgery group (ENPG) and the intensity-modulated radiotherapy group (IMRT). There were 69 males and 31 females in ENPG, aging from 38 to 55 years. There were 72 males and 28 females in IMRT aging from 41 to 54 years. A retrospective cost-effectiveness analysis of the cohort was conducted using a Markov model. For each modality, data on survival and quality-adjusted life year (QALY) were sourced from relevant articles, and cost prices were included regarding treatment. Weibull distribution was used to estimate time-dependent transition probability. Beta-regression was used to convert the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) to utility. Results: The total cost of ENPG was 29 611.88 yuan, and the total cost of IMRT was 110 082.51 yuan. The incremental cost-effectiveness ratio (ICER) of ENPG versus radiotherapy for locally rNPC was -85 555.88 yuan/QALY, which was less than 3 times of Chinese gross domestic product (GDP) per capita. Sensitivity analysis showed that the cost of IMRT had the greatest impact on ICER. ICER was stable within 10% fluctuation of all the parameters. Conclusion: It is economical cost-effective to treat locally rNPC with ENGP versus IMRT.

Abstract
Abstract
Introduction
Fibrofatty plaque burden (FFB) is a high-risk, vulnerable plaque feature comprised of an atheromatous core and fibrous cap with increased risk of coronary artery disease (CAD) [1]. Psoriasis (PSO) is a chronic inflammatory disease linked with atherosclerotic risk and premature cardiovascular disease, driven in part by vulnerable plaque rupture [2,3]. Machine learning (ML) previously showed the prognostic value of FFB in predicting 5-year risk of cardiac-related mortality in patients with CAD [4]. Whether ML can predict FFB in psoriasis is understudied.
Purpose
To use ML to identify top determinants of FFB by CCTA in PSO.
Methods
320 consecutive participants with psoriasis were recruited as part of an ongoing cohort study, of whom 307 had FFB analyzed with coronary computed tomography angiography (CCTA) and quantified by QAngio CT (Medis, The Netherlands). 140 out of 182 potential determinants were subjected to ML algorithms analyzed by random forest and validated by 5-fold cross validation to select the top determinants based on R-square criteria. Lipid concentration and size were measured by nuclear magnetic resonance (NMR) and sdLDL-C was calculated by Sampson's formula.
Results
The top 21 determinants of FFB at baseline were grouped into 3 categories: cardiometabolic risk factors (BMI, sex, DBP, mean arterial pressure, exercise, heart rate, glucose, anxiety, psoriasis disease duration), clinical measurements (basophils, platelets, hemoglobin, RBC, alkaline phosphatase, ALT, creatinine, neutrophil-to-lymphocyte ratio), and lipoproteins (LDL particle size, apolipoprotein A1, apolipoprotein B-to-A1 ratio, calculated sdLDL-C).
Conclusion
ML confirmed that FFB strongly correlates with cardiometabolic risk factors, clinical measurements, and lipoproteins. Further investigations into these top determinants of FFB over time may provide insight into potential therapeutic interventions that decrease cardiovascular risk in patients with chronic inflammatory diseases and should be validated in larger studies.

Abstract
Objective: To investigate the value of high-risk HPV E6/E7 mRNA in situ hybridization in the grading of cervical squamous intraepithelial neoplasia (CIN). Methods: A total of 261 cases with diagnosis of CIN and cervical squamous cell carcinoma (SCC) at west China University Second Hospital, Sichuan University from July 2019 to June 2020 were collected, including 60 cases of CIN1, 41 cases of CIN2, 51 cases of CIN3, 72 cases of SCC, and 37 cases of normal cervical control tissue (10 HPV negative and 27 HPV positive). All pathologic tissues were made into tissue microarrays, and HE staining, HPV E6/E7 mRNA in situ hybridization (ISH) and p16 immunohistochemical (IHC) staining were performed respectively. The staining was assessed by light microscopy, and the positive rate and positive pattern were analyzed statistically. Results: HPV mRNA ISH in CIN1 mainly showed spot staining in predominantly basal to mid-epithelial layers (≤BME) with a diffuse nuclear signals in the superficial layer (supD), that is, the pattern of ≤BME+supD; in CIN2, it mainly showed spot staining in predominantly basal to above mid-epithelial but not the full layer (>BME) and some cases with supD staining, that is, the pattern of>BME+supD; In CIN3, the mainly pattern was >BME, and the spot staining was distributed throughout the epithelium. In CIN1, CIN2 and CIN3, there were significantly statistical differences among the above three staining patterns (P<0.05). Conclusions: HPV mRNA ISH contributes to the accurate diagnosis and grading of CIN, and has better specificity than p16 IHC staining.

Abstract
Objective: To explore the effect of the combined effect of noise and heat on occupational hearing loss of workers by using Meta-analysis method. Methods: In August 2020, the Chinese and English literature on the relationship between exposure to noise and heat and occupational hearing loss published from January 2005 to August 2020 by CNKI, China Biomedical Literature Service System, Wanfang Data Knowledge Service Platform, VIP Official Database, Medline and PubMed Databases were searched, using noise, heat or hyperthermia, hearing as keywords. The selected data were analyzed by Stata 12.0 software, and the combined OR (95% CI) value included in the literature was calculated. Sensitivity analysis was used to explore the source of heterogeneity and analyze publication bias. Results: A total of 14 literatures (14 in Chinese, 0 in English) were included in the analysis, and 38654 subjects were included, including 6411 workers in the noise and heat combined effect group and 32243 workers in the noise alone group. The probability of hearing loss in the noise and heat combined effect group was 1.39 times higher than that in the noise alone group (95%CI: 1.14-1.69). The effect size OR was stable after sensitivity analysis, and there was no publication bias in the included literatures tested by Egger's and Begg's Method (z=0.38, P=0.702, t=-0.74, P=0.476) . Conclusion: Simultaneous exposure to noise and heat may increase the risk of hearing loss for workers in noisy workplaces.

Abstract
Objective: A method for the determination of acetochlor and its metabolites in urine by liquid chromatography-tandem mass spectrometry (LC-MS/MS) was established. Methods: After cleaned-up by a HLB extraction cartridges, the urine was eluted with 1% acetic acid acetonitrile solution. The target compounds were separated by ACQUITY UPLC®HSS T3 Column (2.1 mm×100 mm×1.8 μm) by using 1% formic acid solution and acetonitrile as mobile phase with gradient elution program, and analyzed in positive electrospray ionization mode by liquid chromatography tandem mass spectrometry. Results: All the target compounds showed good linear relationships in the range of 1-50 μg/L, and the correlation coefficients (r) were higher than 0.997. The recoveries rates at three different spiked levels for all target compounds in blank matrices were 107.6%-129.1%, and the relative standard deviations (RSD) were 1.5%-9.9% (n=6) . The limits of detection and quantitation of the method were 0.04-0.11 μg/L and 0.15-0.42 μg/L, respectively, and target substances were detected in all urine samples from occupational exposure workers to acetochlor. Conclusion: This method is suitable for rapid screening and analysis of acetochlor and metabolites in urine with the advantages of accuracy, rapidity, simplicity, high sensitivity and good specificity.

Abstract
Delimiting species requires multiple sources of evidence. Here, we delimited two varieties of Halenia elliptica (Gentianaceae) using several lines of evidence, including morphological traits and mating system in a sympatric population, phylogenetic relationships based on nrITS and cpDNA (rpl16) data, and complete chloroplast genome sequences. Comparative analysis of 21 morphological traits clearly separates the two varieties of H. elliptica. Examination of the flowering process and pollination treatments indicate that H. elliptica var. grandiflora produces seeds via outcrossing, whereas H. elliptica var. elliptica produces seeds via mixed mating. Furthermore, hand-pollinated hybridization of the two varieties produced no seeds. Observations of pollinators showed that when bees began a pollination bout on H. elliptica var. grandiflora they preferred to continue pollinating this variety; however, when they began a pollination bout on H. elliptica var. elliptica, they showed no preference for either variety. Phylogenetic analysis confirmed the monophyly of H. elliptica, which was further divided into two monophyletic clades corresponding to the two varieties. A large number of variants from the chloroplast genomes reflected remarkable genetic dissimilarities between the two varieties of H. elliptica. We recommend that the two varieties of H. elliptica should be revised as two species (H. elliptica and H. grandiflora). Our findings indicate that H. elliptica varieties may have split into two separate species due to a shift in mating system, changes in flowering phenology and/or post-pollination reproductive isolation.

Abstract
This large-scale study aimed to determine the long-term influences of potential prognostic predictors and progression-free interval (PFI) criteria for grading platinum-sensitivity in ovarian clear cell carcinoma (OCCC). We retrospectively reviewed the medical records of OCCC patients presenting at nine tertiary centres (1995−2015), and evaluated patient characteristics, therapeutic factors, clinical outcomes, and hazard ratios for disease progression and death. We enrolled 536 patients (median follow-up, 36.6 months) and developed newly defined distributions of PFIs (seven and 14 months) for grading platinum sensitivity. In the multivariate model, preoperative CA125 levels and chemo-response independently predicted early-stage progression-free survival (PFS) risk. Post-progression cytoreduction correlated with reduced mortality risk. No unfavourable outcomes were observed with respect to coexisting endometriosis, fertility-sparing strategies, or platinum-based regimens. A PFI of <7 months, the strongest predictor of both post-progression mortality and second relapse risks, correlated with chemo-resistance, advanced tumour stage, and shortened post-progression survival. Chemotherapy regimens commonly used in front-line or relapse settings were limited in improving prognoses, especially in the advanced-stage cohort. Clinical trials of novel targeted agents and/or innovative biomarkers for chemoresistance should be comprehensively investigated and offered early to advanced-stage patients or those with OCCC progression occurring within seven months after receiving chemotherapy.

Abstract
Objective: To investigate the role and mechanism of long non-coding RNA (lncRNA) C9ORF139 targeting micro RNA(miR)-24-3P/TAOK1 in regulating the proliferation of acute myeloid leukemia (AML) cells. Methods: AML cells HL-60 and THP-1 were purchased from the Chinese Academy of Sciences and divided into 4 groups:group A was negative control group (siNC group), group B was interference C9ORF139 group (siC9ORF139 group), group C was siC9ORF139+miR-24-3p inhibitor group, and group D was miR-24-3P+TAOK1 overexpression group (oe-TAOK1 group). Real-time fluorescence quantitative reverse transcription PCR was used to detect the expression levels of AML cell lines of HL-60 and THP-1 in four groups. Cell Counting Kit-8 assay was performed to measure cell proliferation. Flow cytometry was applied to analyze cell apoptosis. Transwell test was applied to detect cell migration and invasion ability. Western blot was used to detect p-serine/threonine kinase (p-raf) and p-mitogen activation proteinkinase (p-MEK), p-extracellular regulatory protein kinase (p-ERK) expression. The luciferase reporter gene plasmid was constructed to verify the binding ability of C9ORF139,miR-24-3P and TAOK1.Nude mice were inoculated with subcutaneous tumor cells of HL-60 (group A) and HL-60 (group B). Results: After the C9ORF139 gene was knocked down and cultured for 120 h, The cell proliferation ability (0.62±0.02, 0.82±0.02), migration ability (0.22±0.03, 0.05±0.01), invasion ability (0.20±0.02, 0.13±0.03) of group B were all lower than that of group A (1.30±0.02, 1.83±0.07; 0.99±0.02, 0.99±0.02; 1.00±0.01, 1.00±0.01) (all P<0.05). When co-transfected with miR-24-3 inhibitor, cell proliferation ability, migration ability and invasion ability were all higher in group B (all P<0.05). When co-transfected with miR-24-3P and oe-TAOK1 plasmid, cell proliferation ability, migration ability and invasion ability were all higher than group B (all P<0.05).When the C9ORF139 gene in the cells was knocked down, the apoptosis level of group B (28.56±8.07, 17.74±1.91) were higher than those of group A (0.31±0.27, 2.49±0.33)(all P<0.05); when co-transfected with miR-24-3P inhibitor, the apoptosis level (2.34±0.09, 3.06±0.06) were lower than those in group B (all P<0.05); when co-transfected with miR-24-3P and oe-TAOK1 in the plasmid group, the apoptosis level (2.16±1.29, 4.80±0.37) were also lower than those of group B (all P<0.05). In HL-60 and THP-1 cells, when C9ORF139 was not mutated, the luciferase activity of miR-24-3P group was lower than that of the miR-NC group (P<0.05). When the binding site with miR-24-3p in C9ORF139 sequence was mutated, the luciferase activity in miR-24-3p group was equivalent to that in miR-NC group (P>0.05).When TAOK1 was not mutated; the luciferase activity of miR-24-3P group was lower than that of group A (P<0.05). When the binding site with miR-24-3p in TAOK1 sequence was mutated, the luciferase activity in miR-24-3p group was equivalent to that in miR-NC group (P>0.05).When the C9ORF139 gene in HL-60 cells was knocked down and cultured for 72 h, the phosphorylation expression levels of Raf, MEK and ERK molecules in group B were significantly lower than those in group A (all P<0.05). By day 14, the tumor volume in the group A was greater than the tumor cell volume in the group B [(284.49±57.61) vs (125.70±18.64) mm3, P=0.017]. The tumor weight of HL-60 in group A was heavier than that of group B [(847.80±159.36) vs (408.40±113.16) mg, P=0.001]. Conclusions: LncRNA C9ORF139 regulates TAOK1 by sponging miR-24-3P to promote the proliferation, invasion and migration of acute myeloid leukemiacell.In vivo experiments have confirmed that the expression of C9ORF139 can promote the growth of subcutaneous tumors in AML nude mice.

Abstract
Objective: To establish the morphological reference values for the differential count of white blood cells in peripheral blood smear as well as nucleated cells and megakaryocytes in bone marrow smear. Methods: From April 2012 to June 2020, 4 221 healthy donors for hematopoietic stem cell transplantation in Hebei Yanda Lu Daopei Hospital were selected. The median age was 36 (3-72) years old, including 2 520 males and 1 701 females. They were divided into four groups according to age: children group, with age≤14 years old [n=334, 11 (3-14) years old], youth group, with age >14 years old and <45 years old [n=2 855, 33 (15-44) years old], middle-aged adult group, with age ≥45 years old and < 60 years old [n=929, 49 (45-59) years old], and older adult group, with age ≥60 years old [n=103, 62 (60-72) years old]. Gender subgroups were established in each age group. According to different hematopoietic characteristics, the children group were divided into two subgroups: children group 1 [n=48, 6 (3-7) years old] and children group 2 [n=286, 11 (8-14) years old]. According to the clinical routine, 100 white blood cells in peripheral blood, 200 nucleated cells in bone marrow, and cell numbers/4.5 cm2 for megakaryocytes were classified and counted. The results of cell count in different age and gender groups were compared, and the reference values of morphological classification were established for different groups with statistical or clinical significance. Results: Due to the existence of statistically significant differences between children and adult groups and different gender subgroups in adults (all P<0.05), the reference values were established for children group and adult gender subgroups. The counts of segmented neutrophils and lymphocytes in peripheral blood were 46.65(43.97-49.32)% and 44.00(10.60-65.10)% in children group 1, 50.73(49.50-51.96)% and 39.55 (38.36-40.74)% in children group 2, and 57.00 (39.00-75.23) % and 33.00 (17.00-52.00) % in adult group, respectively. Bone marrow segmented neutrophils, orthochromatic erythroblasts, and mature lymphocytes were 11.54 (10.68-12.41)%, 14.20 (13.19-15.21)%, and 23.99 (22.06-25.92)% in children group 1, 12.50 (7.00-21.50)%, 15.00(9.50-25.50)%, and 21.02 (20.24-21.81)% in children group 2, 13.50 (7.50-21.00)%, 16.50 (10.50-26.00)%, and 15.50 (7.50-26.00)% in adult male group, and 14.50 (8.00-24.50)%, 14.50 (9.00-23.00)%, and 17.50 (8.50-29.00)% in adult female group, respectively. The myelopoiesis/erythropoiesis ratio in children group, adult male group and adult female group was 1.86∶1 (1.14∶1-3.23∶1), 1.96∶1 (1.12∶1-3.19∶1), 2.22∶1 (1.30∶1-3.69∶1), respectively. The numbers of granular megakaryocytes and thromocytogenic megakaryocytes were 138 (25-567) cells/4.5cm2 and 86 (13-328) cells/4.5 cm2 in children group, and 92 (13-338) cells/4.5 cm2 and 38 (3-162) cells/4.5 cm2 in adult group, respectively. Conclusion: The morphological reference values for the differential count of white blood cells in peripheral blood smear as well as nucleated cells and megakaryocytes in bone marrow smear are successfully established, which is helpful to improve the application of morphological examination in disease screening, diagnosis and monitoring.

Abstract
Abstract
Introduction/Objective
Pancreatic metastases are rare, and the most common neoplasms are carcinomas from the kidney, lung, and breast.
Methods/Case Report
We present four cases of breast ductal carcinoma in patients with metastases to the pancreas diagnosed by endoscopic ultrasound guided fine needle aspiration (EUS-FNA). The four female patients ranged from 37 to 64 years in age. Three patients had breast cancer histories, ranging from 1 to 21 years. The patient without cancer history was found to have breast mass also. Two patients had triple negative breast ductal carcinoma. The breast cancer biomarkers on the other two patients showed ER+, PR-, Her2 3+, and ER-, PR-, Her2 3+, respectively. Two patients had histories of metastatic breast cancer involving bone, liver and brain. All patients presented with symptoms associated with pancreatic mass. By imaging, solitary pancreatic head masses were found in three patients, ranging from 2.4 to 3.7 cm. One patient had two pancreatic masses (head, 2.6 cm; body, 2.9 cm). EUS-FNAs targeting the pancreatic head masses were performed on the four patients. Cell blocks were available for all except one (due to limited cells), which had subsequent histology diagnosis.
Results (if a Case Study enter NA)
FNAs demonstrated loosely cohesive tumor cells with enlarged, hyperchromatic nuclei, occasional prominent nucleoli, and occasional intracytoplasmic vacuoles, morphologically and immunohistochemically (CK7 +, GCDFP-15 focally +, CA19.9 -, biomarkers similar to primary tumors) consistent with breast primary. Follow-up revealed three patients expired one month, 2.5 years, and 5 years post-diagnosis, respectively. One patient without prior cancer history has been stable for 7 years.
Conclusion
Our study demonstrates the clinicopathological features of four cases of breast ductal carcinoma metastasized to the pancreas. We emphasize the important role of EUS-FNA for diagnoses of pancreas metastases. The finding of two of four cases with triple negative biomarkers may raise the importance of close follow-up in these patients for pancreatic metastasis.

Abstract
Objective We aimed to investigate the effects of dinalbuphine sebacate (DNS), fentanyl-based patient-controlled analgesia (PCA), and conventional analgesia (CA) for pain management after laparotomy for gynecologic cancers. Methods A total of 137 eligible patients who underwent laparotomy through a midline incision wound for gynecologic cancer between July 2019 and June 2020 were retrospectively evaluated. The patients were divided into three groups as follows: the intramuscular DNS, intravenous PCA, and CA groups. Postoperative pain (POP) intensity as measured with a numerical rating scale (NRS), total consumption of analgesics, and incidence of treatment-emergent adverse events were compared between the three groups. Results The DNS group showed significant reduction in NRS pain intensity than the PCA and CA groups on day 1 (4.8 vs 6.2, p < 0.01 and 6.2, p < 0.05, respectively), day 2 (3.0 vs 4.7, p < 0.01 and 4.8, p < 0.001, respectively), day 3 (2.0 vs 3.9, p < 0.001 and 3.5, p < 0.001, respectively), day 4 (1.1 vs 3.1, p < 0.001 and 2.9, p < 0.001, respectively), and day 5 (0.7 vs 2.3, p < 0.001 and 2.4, p < 0.001, respectively). The total consumption of morphine equivalents per day was similar between the DNS and PCA groups (142.8 ± 7.3 mg vs 137.7 ± 70.0 mg, p = 0.8032) and lowest in the CA group (11.7 ± 30.7 mg, p < 0.0001). The overall safety profile was comparable between the DNS, PCA, and CA groups. The patients in the DNS group complained less of dizziness postoperatively than those in the PCA group (27% vs 47%) and had less nausea than those in the CA group (13% vs 33%). Conclusion A single DNS injection was more effective for relieving POP than PCA and CA in the patients who had a longitudinal incision for gynecologic cancer surgery. DNS was well tolerated and had less adverse effects than PCA and CA.

Abstract
Objective: In order to improve the understanding and clinical treatment of Chlamydia psittaci pneumonia, we analyzed the clinical manifestations, laboratory test results and imaging features of 8 patients. Methods: We collected the clinical data of 8 patients with Chlamydia psittaci pneumonia diagnosed by metagenomic next-generation-sequencing (mNGS) from November 2018 to February 2020, including clinical features, chest CT scan, pathological features and antibiotic use. Results: A total of one male and 7 females, aged from 45 to 85 years(median 62 years), were included in this study. All the patients had high fever, cough and most had expectoration (6/8). The leukocyte count and PCT level were mostly normal (7/8). However, we observed decreased lymphocyte count(5/8), elevated C-reactive protein in all patients, and increased ESR in most patients (7/8). The chest CT of all the patients showed large patchy consolidation, with one case having pleural effusion. The pathological manifestations were nonspecific, showing infiltration of inflammatory cells and exudation. Moxifloxacin and/or doxycycline were administered after diagnosis, and the course of treatment lasted from 14 to 21 days.Chest CT showed absorption of lesions following treatment Conclusions: Chlamydia psittaci pneumonia showed certain characteristics, including high fever with pulmonary patchy consolidation, and normal white blood cell count. Molecular diagnostic methods such as mNGS could lead to rapid diagnosis and treatment which can shorten the course of hospitalization and thus improve prognosis.

Abstract
5540 Background: The objective of this study is to evaluate the safety and efficacy of adding bevacizumab to dose-dense adjuvant chemotherapy with bevacizumab maintenance after neoadjuvant chemotherapy (NAC) and interval debulking surgery (IDS) for stage III/IV ovarian, tubal, and primary peritoneal cancer. Methods: This phase II clinical trial using Simon's minimax two-stage design was conducted. At the first stage, 13 subjects were enrolled, and the trial would proceed to second stage if ≤3 subjects discontinued treatment for study-defined significant adverse events (AEs). Patients with stage III/IV ovarian, tubal, and primary peritoneal cancer deemed not feasible for primary cytoreductive surgery were enrolled after 3 to 4 cycles of NAC and IDS without disease progression. NAC could be either weekly paclitaxel (80mg/m2) (dose-dense) plus 3-weekly carboplatin (AUC5-6) or 3-weekly conventional schedule. After IDS, postoperative dose-dense adjuvant chemotherapy for 3 cycles at least (best to 6 cycles), and 3-weekly bevacizumab 15mg/kg was given since postoperative cycle 2. Further 3-weekly maintenance bevacizumab 15mg/kg was given intravenously for 17 cycles. Results: Of the 22 enrolled subjects, 13 (59.1%) had no gross lesion after IDS. Of the 13 subjects enrolled on the 1st stage, one study-defined significant AE occurred, therefore the trial proceeded to the 2nd stage (n = 9). The median progression-free survival (PFS) was 22.1 months (95% confidence interval [CI], 13.7 – 30.5), and the median overall survival (OS) was 49.2 months (95% CI, 33.8 – 64.6). Peritoneal Cancer Index score at entering abdomen during IDS was significant for PFS (>12 vs ≤ 12: p = 0.003). One of the 22 subjects did not receive any study treatment. In the safety analysis (n = 21), grade 3/4 AEs included thrombocytopenia of 38.1%, neutropenia 71.4%, and anemia 28.6%. Study-defined significant AEs of bowel perforation, poor-healing wound, and hypertension were found in 1 case each, respectively. Conclusions: This phase II trial demonstrated adding bevacizumab to dose-dense adjuvant chemotherapy with bevacizumab maintenance after NAC was feasible with tolerable toxicity and comparable PFS/OS as compared to other studies using bevacizumab in the NAC phase or dose-dense scheduling throughout. Clinical trial information: NCT02022917.

Abstract
Objective: To investigate the predictive value of myoglobin (Mb) for the prognosis of sepsis related chronic critical illness (CCI). Methods: Retrospective study was conducted on septic patients with the length of ICU stay equal or greater than 14 days, and sepsis-related organ failure assessment (SOFA) score equal or greater than 2 on the 14th day in ICU in the First Department of Critical Care Medicine at the First Affiliated Hospital of Sun Yat-sen University from January 2017 to March 2020. Patients' clinical and laboratory data were collected on the 1st and 14th day in ICU. The survival on day 28 in ICU was recorded. According to the myoglobin levels on day 1 and day 14, all subjects were divided into myoglobin elevation group and decline group. Kaplan-Meier survival curve was used to compare the cumulative survival rate at day 28. Cox regression analysis was used to analyze the independent risk factors of mortality. Receiver operating characteristic (ROC) curve was used to analyze the prognostic value of myoglobin. Results: A total of 131 patients with sepsis related CCI were recruited, including 58 patients in the elevation group and 73 in the decline group. The Mb level in elevation group on day 1 was significantly lower than that in decline group [172.40(59.99, 430.53) μg/L vs. 413.60(184.40, 1 328.50) μg/L, Z=3.749, P=0.000], and the Mb level on day 14 was the opposite change in two groups [483.65(230.38, 1 471.75)μg/L in elevation group vs. 132.20(76.86, 274.35)μg/L in decline group, Z=5.595, P=0.000]. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate of the elevation group was significantly lower than that of decline group (χ²=7.051, P=0.008). Cox ratio regression analysis suggested that elevated myoglobin was an independent risk factor for 28-day mortality in septic patients with CCI (OR=2.534, 95%CI 1.212-5.295, P=0.013). ROC curve analysis suggested that the sensitivity of myoglobin elevation in predicting mortality related to CCI within 28 days was 64.5%, and the specificity was 32.0% with area under the curve(AUC) 0.661(95%CI 0.550-0.773,P=0.007) and Jorden Index was 0.325. Conclusion: Elevated myoglobin, an independent risk factor for mortality within 28 days in ICU, can predict the prognosis of sepsis related chronic critical illness.

Abstract
Most oral squamous cell carcinoma (OSCC) tumors arise from oral premalignant lesions. Oral submucous fibrosis (OSF), usually occurring in male chewers of betel quid, is a premalignant stromal disease characterized by a high malignant transformation rate and high prevalence. Although a relationship between the inhabited microbiome and carcinogenesis has been proposed, no detailed information regarding the oral microbiome of patients with OSF exists; the changes of the salivary microbiome during cancer formation remain unclear. This study compared the salivary microbiomes of male patients with OSCC and a predisposing OSF background (OSCC-OSF group) and those with OSF only (OSF group). The results of high-throughput sequencing of the bacterial 16S rRNA gene indicated that OSF-related carcinogenesis and smoking status significantly contributed to phylogenetic composition variations in the salivary microbiome, leading to considerable reductions in species richness and phylogenetic diversity. The microbiome profile of OSF-related malignancy was associated with increased microbial stochastic fluctuation, which dominated the salivary microbiome assembly and caused species co-occurrence network collapse. Artificial intelligence selection algorithms consistently identified 5 key species in the OSCC-OSF group: Porphyromonas catoniae, Prevotella multisaccharivorax, Prevotella sp. HMT-300, Mitsuokella sp. HMT-131, and Treponema sp. HMT-927. Robust accuracy in predicting oral carcinogenesis was obtained with our exploratory and validation data sets. In functional analysis, the microbiome of the OSCC-OSF group had greater potential for S-adenosyl-l-methionine and norspermidine synthesis but lower potential for l-ornithine and pyrimidine deoxyribonucleotide synthesis and formaldehyde metabolism. These findings indicated that the salivary microbiome plays important roles in modulating microbial metabolites during oral carcinogenesis. In conclusion, our results provided new insights into salivary microbiome alterations during the malignant transformation of OSF.

Abstract
Human papillomavirus (HPV) is the well‐established etiologic factor for cervical neoplasia. Cervical conization constitutes an effective treatment for high‐grade cervical intraepithelial neoplasia (HG‐CIN). We conducted an observational study for long‐term outcomes and HPV genotype changes after conization for HG‐CIN. Between 2008 and 2014, patients with newly diagnosed HG‐CIN before conization (surveillance new [SN] group) and those who had undergone conization without hysterectomy (surveillance previous [SP] group) were enrolled. HPV testing and Pap smear were performed periodically for the SN and SP (collectively S) groups. All other patients receiving conization for HG‐CIN during the study period were identified from our hospital database. Those eligible but not enrolled into our study were assigned to the non‐surveillance (non‐S) group. For the S group (n = 493), the median follow‐up period was 74.3 months. Eighty‐four cases had recurrent CIN Grade 2 or worse (CIN2+) (5‐year cumulative rate: 14.8%), of which six had invasive cancer. Among the 84 patients, 65 (77.4%) exhibited type‐specific persistence in the paired HPV results, whereas only 7 (8.3%) harbored new HPV types that belonged to the 9‐valent vaccine types. Among the 7397 non‐S patients, 789 demonstrated recurrent CIN2+, of which 57 had invasive cancer. The stages distribution of those progressed to invasive cancer in the non‐S group were more advanced than the S group (P = .033). Active surveillance might reduce the severity of those progressed to cancer. Because a majority of the patients with recurrent CIN2+ had persistent type‐specific HPV infections, effective therapeutic vaccines are an unmet medical need. What's new? High‐grade cervical intraepithelial neoplasia (HG‐CIN), a cervical carcinoma precursor, frequently is caused by high‐risk human papillomavirus (hr‐HPV) infection. HG‐CIN can be treated by cervical conization, though the procedure does not eradicate hr‐HPV, potentially enabling CIN recurrence. Here, in Taiwanese patients, investigation of HPV genotype changes in relation to HG‐CIN status after conization shows that 77.4 percent of patients with recurrent CIN 2 grade or worse (CIN2+) after conization had persistent type‐specific HPV infections. Vaccination against the remaining high‐risk HPVs prevented recurrent CIN2+ in only 8.3 percent of patients, revealing an unmet need for effective therapeutic vaccines.

Abstract
Objective: To compare the clinical diagnosis and outcomes of preterm infants with bronchopulmonary dysplasia (BPD) under two different diagnostic criteria. Methods: A retrospective study was performed in 157 preterm infants who were admitted to Neonatal Intensive Care Unit of the Children's Hospital, Zhejiang University School of Medicine from January 2015 to December 2018. Enrolled infants, with gestational age <32 weeks and survived >14 days, met the 2001 National Institute of Child Health and Human Development(NICHD) definition of moderate and severe BPD or died between 14 days of postnatal age and 36 weeks owing to persistent parenchymal lung disease and respiratory failure. The severities of BPD were revaluated according to the 2018 revised definition of BPD proposed by NICHD. Characteristics and outcomes of these infants were compared with the two different diagnostic criteria with t-test, nonparametric test or Chi-square test. Results: In the 157 enrolled infants (100 males), severities of BPD were classified as moderate in 62, severe in 84 and unclassifiable in 11 according to the 2001 NICHD criteria, while grade Ⅰ in 51, Ⅱ in 29, Ⅲ in 66 and ⅢA in 11 infants respectively according to the 2018 NICHD criteria. Duration of oxygen therapy, positive pressure ventilation and endotracheal intubation in grade Ⅱinfants of 2018 criteria were much longer than that in moderate infants of 2001 criteria (80 (65, 95) vs. 65 (59, 77) d, 52 (38, 58) vs.30 (19, 48) d, 10 (2, 17) vs.4 (0, 12) d, Z=-2.995, -3.750, -2.073, all P<0.05). Mortality of moderate and severe infants in 2001 criteria was 10.3% (15/146), while mortality of BPD in 2018 criteria was 16.6% (26/157). Mortality of grade Ⅲ and ⅢA BPD in 2018 criteria was much higher than mortality of severe BPD in 2001 criteria (33.8% (26/77) vs. 17.9%(15/84), χ(2)=5.357, P<0.05). Conclusion: Definition and classification of BPD based on 2001 NICHD criteria may cause missed or unclassified cases, resulting in the underestimation of the morbidity and mortality of infants with severe BPD.

Abstract
Objective: To explore the coexisting mutations in NPM1 mutated elderly patients with acute myeloid leukemia(AML). Methods: The clinical data of 152 elderly adults(aged≥60 years) and 49 young adults(aged 18-45 years) with AML between June 2013 and December 2018 in outpatient and hospitalized patients of Changzhou Second People's Hospital and Wuxi Second People's Hospital were retrospectively analyzed. A total of 51 gene mutations were detected using targeted next-generation sequencing (NGS) and sanger sequencing. The general clinical characteristics, the occurrence of coexistence gene mutations, the correlation between coexistence gene mutations and some clinical parameters, and the initial induction remission rate between elderly and young adult AML patients with NPM1 mutations were analyzed and compared. Results: NPM1 mutations were detected in 46 of 152 elderly AML patients. Thirty eight patients (82.6%) with NPM1 mutations carried other gene mutations at the same time, among whom 8 patients (17.4%) carried NPM1 mutations alone, while 14(30.4%) carried 2, 16 (34.8%) carried 3, and 8 (17.4%) carried ≥ 4 mutations. NPM1 mutations frequently co-occurred with FLT3-ITD15 cases (32.6%) , DNMT3A10 (21.7%) , TET26 (13.4%) and FLT3-TKD5 (10.9%) . Compared with young adults with NPM1 mutations, elderly patients had higher TP53, FLT3-TKD rates, lower incidence of DNMT3A, RAS mutation (all P<0.05) and lower coexistence rate of 4 gene mutations (P=0.002).The presence of ≥ 4 mutations was found to be significantly associated with higher white blood level than those in patients with single, double and 3 mutations coexisted in elderly adults AML patients(all P<0.05). With the increase of the amount of mutations, the complete remission(CR) rate decreased gradually after the initial induction. Patients who carried 3 or more mutations showed a lower CR rate than those with single gene mutations (all P<0.05) . Patients who carried>4 genes also showed a significantly lower CR rate than those with double gene mutations (P=0.031). Patients with FLT3-ITD mutations exhibited higher white blood level and lower CR rate than that in nonmutant type group (all P<0.05). The CR rate of patients with DNMT3A mutation was also significantly lower than that with nonmutant type (P=0.033). However, patients with FLT3-TKD mutations showed a higher platelet level than that with nonmutant type (P=0.019). There was no significant difference in CR rate and peripheral blood cell level between TET2 mutated and nonmutant type. Conclusion: NPM1 mutated elderly patients with AML commonly show additional mutations, and the amount and type of coexisting mutations have an influence on the clinical features and CR rate of elderly patients with AML.

Abstract
This paper describes an original design leading to the field effect passivation of Si n+-p junctions. Ordered Ag nanoparticle (Ag-NP) arrays with optimal size and coverage fabricated by means of nanosphere lithography and thermal evaporation, were embedded in ultrathin-Al2O3/SiN x :H stacks on the top of implanted Si n+-p junctions, to achieve effective surface passivation. One way to characterize surface passivation is to use photocurrent, sensitive to recombination centers. We evidenced an improvement of photocurrent by a factor of 5 with the presence of Ag NPs. Finite-difference time-domain (FDTD) simulations combining with semi-quantitative calculations demonstrated that such gain was mainly due to the enhanced field effect passivation through the depleted region associated with the Ag-NPs/Si Schottky contacts.

Abstract
Objective: To observe the effect of sepsis single-disease manage system on the improvement of sepsis treatment and the value in predicting mortality in patients with sepsis. Methods: A retrospective study was conducted. Patients with sepsis admitted to the Department of Surgical Intensive Care Unit of Sun Yat-Sen University First Affiliated Hospital from September 22, 2013 to May 5, 2015 were enrolled in this study. Sepsis single-disease manage system (Rui Xin clinical data manage system, China data, China) was used to monitor 25 clinical quality parameters, consisting of timeliness, normalization and outcome parameters. Based on whether these quality parameters could be completed or not, the clinical practice was evaluated by the system. The unachieved quality parameter was defined as suspicious parameters, and these suspicious parameters were used to predict mortality of patients with receiver operating characteristic curve (ROC). Results: A total of 1 220 patients with sepsis were enrolled, included 805 males and 415 females. The mean age was (59±17) years, and acute physiology and chronic health evaluation (APACHE Ⅱ) scores was 19±8. The area under ROC curve of total suspicious numbers for predicting 28-day mortality was 0.70; when the suspicious parameters number was more than 6, the sensitivity was 68.0% and the specificity was 61.0% for predicting 28-day mortality. In addition, the area under ROC curve of outcome suspicious number for predicting 28-day mortality was 0.89; when the suspicious outcome parameters numbers was more than 1, the sensitivity was 88.0% and the specificity was 78.0% for predicting 28-day mortality. Moreover, the area under ROC curve of total suspicious number for predicting 90-day mortality was 0.73; when the total suspicious parameters number was more than 7, the sensitivity was 60.0% and the specificity was 74.0% for predicting 90-day mortality. Finally, the area under ROC curve of outcome suspicious numbers for predicting 90-day mortality was 0.92; when suspicious outcome parameters numbers was more than 1, the sensitivity was 88.0% and the specificity was 81.0% for predicting 90-day mortality. Conclusion: The single center study suggests that this sepsis single-disease manage system could be used to monitor the completion of clinical practice for intensivist in managing sepsis, and the number of quality parameters failed to complete could be used to predict the mortality of the patients.

Abstract
Objective: To evaluate the efficacy of pleural abrasion in treatment of spontaneous pneumothorax with video-assisted thoracic surgery (VATS) for bullae resection. Methods: The clinical data of 158 patients with initial spontaneous pneumothorax who underwent video-assisted thoracic wedge resections with or without pleural abrasion in Henan Provincial People's Hospital from June 2010 to June 2015 were retrospectively analyzed. The patients were assigned to two equal groups according to whether pleural abrasion was applied or not: experimental group (with pleural abrasion) and control group (without pleural abrasion); and there were 79 patients in each group.There were 62 males and 17 females aged 15-60 years (mean age 34 years) in pleural abrasion group. And there were 70 males and 9 females aged 18-60 years (mean age 38 years) in non-pleural abrasion group.After surgery, all patients were evaluated for postoperative pain, chest tube removal time, hospital stay and other complications.Independent samples t test was used to compare the data between groups. Results: Surgeries for 158 patients were performed successfully.No mortality occurred.There was no conversion to thoracotomy.Postoperative pain, operation time, intraoperative blood loss, chest tube removal time, pleural canals flowand average hospital stay in non-pleural abrasion group was significantly lower for 4.4, 19 minutes, 10 ml, 21 hours, 87 ml and 1.4 days respectively when compared with those in pleural abrasion group (t=32.478, 7.140, 11.093, 7.288, 10.246, 8.070, all P<0.05). There was no missing case with a follow-up of 30 months.No complications, such as pneumothorax, was observed. Conclusions: Postoperative pain, chest tube removal time and hospital stay in non-pleural abrasion group are all lower than those in pleural abrasion group.And there is no significant difference in the recurrence of pneumothorax between the two groups after VATS bullae resection.

Abstract
OBJECTIVE To discuss the surgical technique and common complications from the microsurgical treatment of giant intracranial vestibular schwannoma via suboccipital retrosigmoid approach and to propose strategies for minimizing such complications. METHODS Surgical outcomes and complications were evaluated in a consecutive series of 657 unilateral giant vestibular schwannomas treated in Shanghai Huashan Hospital via suboccipital retrosigmoid approach from 1999 to 2014. According to the international classification of vestibular schwannoma, giant tumor means tumor's size over 4 cm in diameter. Clinical status and complications were assessed postoperatively within 14 days and at follow-ups (range, 6-191 months; mean, 59.6 months). RESULTS Follow-up data were available for 566 of the 657 patients (86.1%). The most frequent clinical symptoms were hearing loss in different levels (100%), deafness (36.4%), facial numbness (68.8%). Total tumor resection was achieved in 556 patients (84.6%), subtotal resection in 99 patients (15.1%), and partial resection in 2 patients (0.3%). The common postoperative complications included new deafness (49.6%), intracranial infection (7.6%), low cranial nerve defect (7.5%) and pneumonia (6.2%). The facial nerve was preserved anatomically in 589 cases (89.6%) after operation, and the functional valuation of facial nerve according to postoperative House-Brackmann showed 216 patients (32.9%) in grade Ⅰ-Ⅱ, 308 cases (46.9%) in grade Ⅲ, 133 patients (20.2%) in grade Ⅳ-Ⅵ. Long-term followed-up results showed 428 patients (75.6%) in grade Ⅰ-Ⅲ one year after surgical treatment. CONCLUSIONS Many of these complications are avoidable. Surgical experiences and the clinical anatomy of the approach, accompany with using intraoperative nerve monitoring, preoperatively study the individual imaging and clinical data and multidisciplinary cooperation are the key points to avoid the complications of giant intracranial vestibular schwannoma via suboccipital retrosigmoid approach.

Abstract
BACKGROUND A previous study provided evidence for a genetic association between PPP2CA on 5q31.1 and systemic lupus erythematosus (SLE) across multi-ancestral cohorts, but failed to find significant evidence for an association in the Han Chinese population. OBJECTIVES To explore the association between this locus and SLE using data from our previously published genome-wide association study (GWAS). METHODS Single-nucleotide polymorphisms (SNPs) rs7726414 and rs244689 (near TCF7 and PPP2CA in 5q31.1) were selected as candidate independent associations from a large-scale study in a Han Chinese population consisting of 1047 cases and 1205 controls. Subsequently, 3509 cases and 8246 controls were genotyped in two further replication studies. We then investigated the SNPs' associations with SLE subphenotypes and gene expression in peripheral blood mononuclear cells. RESULTS Highly significant associations with SLE in the Han Chinese population were detected for SNPs rs7726414 and rs244689 by combining the genotype data from our previous GWAS and two independent replication cohorts. Further conditional analyses indicated that these two SNPs contribute to disease susceptibility independently. A significant association with SLE, age at diagnosis < 20 years, was found for rs7726414 (P = 0·001). The expression levels of TCF7 and PPP2CA messenger RNA in patients with SLE were significantly decreased compared with those in healthy controls. CONCLUSIONS This study found evidence for multiple associations with SLE in 5q31.1 at genome-wide levels of significance for the first time in a Han Chinese population, in a combined genotype dataset. These findings suggest that variants in the 5q31.1 locus not only provide novel insights into the genetic architecture of SLE, but also contribute to the complex subphenotypes of SLE.

Abstract
Objective: To illuminate the effect of NALP3 inflammasome on regulating the expression of cytokines of macrophages in periodontitis. Methods: RAW264.7 cells were cultured and divided into three groups. The first group stayed normal as control, the second group was stimulated by 1 mg/L Porphyromonas gingivalis (Pg) lipopolysaccharide (LPS), the third group was pretreated with AC-YVAD-CMK (caspase-1 inhibitor) before stimulated with 1 mg/L Pg LPS. RAW264.7 cells pretreated with various concentrations (0, 5, 10, 25, 50, 75, 100, 200 μmol/L) of AC-YVAD-CMK for 2 h, and stimulated by 1 mg/L Pg LPS for 24 h in the third group. After that, cell survival rate were detected by cell counting kit-8. Every group cells gene transcription of NALP3 and interleukin-1β (IL-1β) were detected by quantitative real-time PCR (qPCR) after 6 h, protein expression of NALP3 and IL-1β were separately detected by Western blotting and enzyme linked immunosorbent assay (ELISA) after 24 h, respectively. Results: It is observed that treatment with 5, 10, 25, 50, 75, 100, 200 μmol/L AC-YVAD-CMK did not significantly affect the viability of RAW264.7 cells. qPCR showed that mRNA expression of IL-1β level (1.03±0.08, 5.48±0.22, 4.31±0.20) and NALP3 level (0.96±0.05, 2.62±0.44, 1.73±0.09). Western blotting showed that protein expression of NALP3 level (1.00±0.10, 2.34±0.04, 1.64±0.04), ELISA showed protein secretion of IL-1β level ([40.20±0.25], [61.50±1.81], [52.40±1.91] ng/L). After stimulated by Pg LPS, mRNA and protein expression of IL-1β (P<0.01, P<0.01) and NALP3 (P<0.01, P<0.01) significantly increased; but the expression of IL-1β (P=0.002, P=0.027) and NALP3 (P<0.01, P<0.01) were decreased when pretreated with AC-YVAD-CMK. Conclusions: NALP3 inflammasome signal pathway can be activated by Pg LPS in RAW264.7. Block of the pathway can inhibit Pg LPS-induced secretion of cytokines.

Abstract
Purpose Bevacizumab (BEV) has been used for ovarian cancer (OC) for years in Taiwan, but the associated data related to outcome is scant. This retrospective study reviewed patients with OC treated with BEV and analyzed their results. Patients and methods All patients with OC treated with BEV from 2009 to 2015 in the Linkou branch of Chang Gung Memorial Hospital in Northern Taiwan were included. According to the means of administration, the patients were classified into 6 groups as follows: A—BEV plus chemotherapy (C/T) for initial platinum-resistant (PR) recurrent OC, B—BEV plus C/T for initial platinum-sensitive (PS) recurrent OC, C—BEV alone for recurrent OC, D—BEV plus 1st adjuvant C/T, E—BEV plus neoadjuvant C/T, and F—intraperitoneal (IP) BEV. Progression-free survival (PFS), overall survival (OS), hazard ratios (HRs), overall response rate (ORR), and mean number of BEV cycles were analyzed for groups A to E. Clinical improvement of ascites was assessed for group F. Results A comparison of early use (only one round of prior C/T) versus late use (multiple rounds of prior C/T) in patients of groups A and B showed a superior PFS (8.27 vs. 3.67, p = 0.037) in the early use group. No significant differences were found between groups A and B (PFS: 4.24 vs. 4.17 months, p = 0.690; OS: 10.06 vs. 9.93 months, p = 0.819; mean BEV cycles: 4.63 vs. 5.0 p = 0.992; ORR: 48.1% vs. 53.5%, p = 0.425). Comparing the response and non-response subgroups of patients in groups A and B, a better outcome was associated with endometrioid type cell (HR = 0.28, p = 0.008), good ECOG performance status (HR = 0.51, p = 0.005), and lack of ascites (HR = 0.67, p = 0.004). Comparing group C with groups A plus B, the BEV alone group had a poorer PFS (1.02 VS. 4.19, p = 0.04) and OS (1.42 VS. 9.99 p = 0.001) than the BEV plus C/T group. In group F, a good clinical benefit rate (85.6%) of ascites improvement was noted. Two patients had grade 5 gastrointestinal bleeding and venous/arterial thromboembolic events after administration of BEV. Grade 3 neutropenia and thrombocytopenia occurred more frequently in our study. Conclusion Early use of BEV combined with chemotherapy had a significant benefit in PFS for patients with recurrent OC. BEV plus chemotherapy was better than BEV alone for recurrent OC. In addition, IP BEV was helpful for improving clinical ascites.

Abstract
OBJECTIVES Guidelines regarding whether men who have sex with men (MSM) without symptoms of urethritis should be screened for urethral gonorrhoea differ between countries. We examined the rate of asymptomatic urethral gonorrhoea in MSM using sensitive nucleic acid amplification testing. METHODS This study was conducted on consecutive MSM attending the Melbourne Sexual Health Centre between July 2015 and May 2016 for sexually transmitted infections screening. Gonorrhoea testing with the Aptima Combo 2 (AC2) assay was performed on all urine specimens obtained from MSM, whether symptoms of urethritis were present or not. Men were classified as having: typical discharge if they reported symptoms suggesting purulent discharge; other symptoms if they reported other symptoms of urethritis; and no symptoms if they reported no urethral symptoms. RESULTS During the study period, there were 7941 clinic visits by 5947 individual MSM with 7090 urine specimens obtained from 5497 individual MSM tested with the AC2 assay. Urethral gonorrhoea was detected in 242 urine specimens from 228 individual MSM. The majority (189/242, 78%, 95% CI 73-83) reported typical discharge, 27/242 (11%, 95% CI 8-16) reported other urethral symptoms, and 26/242 (11%, 95% CI 7-15) reported no symptoms on the day of presentation and testing. Among men with urethral gonorrhoea, the proportions with concurrent pharyngeal or rectal gonorrhoea were 32% (134/210) and 64% (74/235), respectively. The mean interval between last reported sexual contact and onset of typical urethral discharge, where present, was 3.9 days. CONCLUSION The findings from our study lend support to guidelines that recommend screening asymptomatic MSM for urethral gonorrhoea.

Abstract
Objective: To compare the clinicopathological features and prognosis of pancreatic cystic neoplasms (PCN) between male and female patients. Methods: A total of 325 patients with histological confirmed PCN from January 2010 to October 2015 were enrolled. The clinicopathological features, laboratory examination, imaging features, treatment and prognosis were analyzed. Results: Of the 325 patients diagnosed as PCN, 104 were male and 221 were female. The average age of male patients was significantly higher than that of female patients (55.0±12.7 vs 47.9±13.4 years, P<0.001), however, the average tumor size of male patients was smaller than that of female patients (3.9±2.7 vs 4.9±3.0 cm, P=0.004). The location of PCN in male patients was predominantly located at pancreatic head and neck, and majority of male patients were mucinous cystic neoplasms. 1-year, 3-year and 5-year survival rates of patients with PCN were 98.5%, 92.6%, and 87.5%, respectively. 1-year, 3-year and 5-year survival rates of male patients were 97.8%, 84.9%, and 77.8%, however, those of female patients were 98.8%, 96.5%, and 92.2%, respectively. Female patients had better prognosis than male patients (χ2=5.543, P=0.019). Elevated CA19-9 (χ2=3.843, P=0.050), perineuronal invasion (χ2=6.250, P=0.012) and lymph node metastasis (χ2=4.529, P=0.033) were important prognostic factors for malignant mucinous cystic neoplasm. Conclusions: Male patients had low incidence of PCN, and were more common for mucinous cystic neoplasm. The long-term outcome of malignant PCN was poor. Even with complete resection, male patients still had worse prognosis. Close follow-up is recommended especially for male patients.

Abstract
Lactic acidosis (LA), a rare but life-threatening adverse effect associated with antiretroviral therapy, has been reported with an increasing frequency since the mid1990s. From June 1994 to June 2002, a total of six patients, four males and two females with a median age of 43 years (range, 30 to 74 years), had been diagnosed with LA. The estimated incidence of LA was 5.1 per 1000 patient-years (PYs) on highly active antiretroviral therapy (HAART) (95% confidence interval [95% CI], 4.5-5.5 per 1000 PYs) and 4.4 per 1000 PY on nucleoside analogues (NAs) (95% CI, 3.9-4.7 per 1000 PYs). Their median body mass index at diagnosis of LA was 17.6 kg/m2 (range 16.3 to 22.6 kg/m2). The median CD4+ lymphocyte count at the initial diagnosis of HIV infection and at the onset of LA was 38 cells/µL (range, 4 to 103 cells/µL) and 108 cells/µL (range, 79 to 224 cells/µL), respectively. The most common symptoms were nausea, vomiting, and dyspnoea. All of the patients had findings suggestive of NA-related mitochondrial toxicity, such as myositis, pancreatitis, fatty hepatitis, peripheral neuropathy or lipodystrophy. The prescribed NA related to LA were stavudine in six patients, lamivudine, five, and didanosine, one. Despite treatment, all patients died of persistent circulatory collapse following LA. The median duration from diagnosis to death was eight days (range, 4-17 days). Our report highlights that clinicians caring for patients with AIDS should be alerted to the potentially fatal LA associated with antiretroviral therapy when patients present with low body mass index, lipodystrophy, unexplained abdominal symptoms, dyspnoea, or elevated aminotransferases.
