Abstract
Nocardia seriolae is a severe bacterial pathogen that has seriously affected the development of aquaculture industry. Largemouth bass (Micropterus salmoides) is a commercially significant freshwater fish that suffers a variety of environmental threats, including bacterial pathogens. However, the immune responses and metabolic alterations of largemouth bass to N. seriolae infection remain largely unclear. We discovered that N. seriolae caused pathological alterations in largemouth bass and shifted the transcript of immune-related and apoptotic genes in head kidney after infection. To answer the aforementioned question, a combined transcriptome and metabolome analysis was employed to explore the alterations in genes, metabolites, and metabolic pathways in largemouth bass following bacterial infection. A total of 3579 genes and 1929 metabolites are significant differentially changed in the head kidney post infection. In response to N. seriolae infection, host modifies the PI3K-Akt signaling pathway, TCA cycle, glycolysis, and amino acid metabolism. The integrated analysis of transcriptome and metabolome suggested that with the arginine metabolism pathway as the core, multiple biomarkers (arg gene, arginine) are involved in the antibacterial and immune functions of largemouth bass. Thus, we hypothesized that arginine plays a crucial role in the immune responses of largemouth bass against N. seriolae infection, and increasing arginine levels suitably is beneficial for the host against bacterial infection. Our results shed light on the regulatory mechanism of largemouth bass resistance to N. seriolae infection and contributed to the development of more effective N. seriolae resistance strategies.

Abstract
Objective: The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach. Methods: Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis. Results: A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score (r = 0.47, P = 0.002), albumin-bilirubin score (r = 0.37, P = 0.001), Lok index (r = 0.36, P = 0.02), liver stiffness (r = 0.58, P = 0.01), and spleen stiffness (r = 0.77, P = 0.01), while negatively correlated with albumin (r = -0.42, P = 0.006). Conclusion: The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Abstract
Ceratomyxa Thélohan, 1892 is one of the largest genera of the sub-phylum Myxozoa, and has a worldwide geographical distribution. Ceratomyxa species mainly infect the gallbladder of marine fish and rarely infect histozoically or coelozoically freshwater fish. In the present study, yellow catfish, Trachysurus fulvidraco (Siluriformes, Actinopteri) collected from the low reach of Yellow River was first found to be infected with an unknown Ceratomyxa species in their gallbladder which was identified to be new to science and nominated as Ceratomyxa huangheensis n. sp. by an integrative taxonomic approach for myxosporeans. Spores are typical of the genus Ceratomyxa, and matures spores are arcuate, with posterior angle of 139.2 ± 11.6 (137.0-156.0)° and rounded ends, and measures 4.7 ± 0.6 (3.3-5.5) μm in length, and 10.7 ± 1.3 (8.5-13.3) μm in thickness. Two spore valves are slightly unequal and present elongated ovoid in the lateral view. Two equal spherical polar capsules, measuring 2.2 ± 0.4 (1.4-2.8) μm × 2.0 ± 0.4 (1.0-2.5) μm in size locates adjacent to the straight suture line. The obtained partial small subunit ribosomal DNA (SSU rDNA) sequence was unique among all myxozoans in GenBank, and the highest similarity is 85.3% with Ceratomyxa sparusaurati, a marine fish-infecting congener. Phylogenetic analysis further indicated that this novel species did not cluster with other freshwater fish-infecting congeners from South America to form an independent clade, but was phylogenetically positioned within the marine fish-infecting clade. The possible presence of different radiation trajectories between Ceratomyxa huangheensis n. sp. and Amazonian freshwater Ceratomyxa lineage was discussed. This is the first report of Ceratomyxa species in the Yellow River basin and the second freshwater Ceraotomyxa species in China, even in Asia.

Abstract
The development of antimicrobial agents with novel model of actions is a promising strategy to combat multiple resistant bacteria. Here, three ruthenium-based complexes, which acted as potential antimicrobial agents, were synthesized and characterized. Importantly, three complexes all showed strong bactericidal potency against Staphylococcus aureus. In particular, the most active one has a MIC of 6.25 μg/mL. Mechanistic studies indicated that ruthenium complex killed S. aureus by releasing ROS and damaging the integrity of bacterial cell membrane. In addition, the most active complex not only could inhibit the biofilm formation and hemolytic toxin secretion of S. aureus, but also serve as a potential antimicrobial adjuvant as well, which showed synergistic effects with eight traditional antibiotics. Finally, both G. mellonella larva infection model and mouse skin infection model all demonstrated that ruthenium complex also showed significant efficacy against S. aureus in vivo. In summary, our study suggested that ruthenium-based complexes bearing a phenyl hydroxide are promising antimicrobial agents for combating S. aureus.

Abstract
PURPOSE To explore the prevalence of nocturnal intermittent hypoxemia (NIH) in a tertiary hospital geriatric department and the relationship between NIH and mild cognitive impairment (MCI) in older adults, and to examine the role of brain-derived neurotrophic factor (BDNF) Val66Met polymorphism. METHODS Older adults aged ≥ 60 were enrolled. NIH and cognitive assessments were conducted. BDNF concentrations and BDNF Val66Met polymorphism were detected for a preliminary exploration of the possible mechanism of the process. RESULTS Of 325 older adults enrolled, 157 (48%) had NIH and were further divided into mild, moderate, and severe NIH groups according to their oxygen desaturation of ≥ 4% per hour of sleep (ODI4). MCI detection rate in the four groups gradually increased, and the differences were statistically significant (chi-square = 4.457, P = 0.035). ODI4 was negatively correlated with MoCA score in all participants (r = - 0.115, P = 0.039) and patients with NIH (r = - 0.199, P = 0.012). After adjusting for sex, age, and cardiovascular risk factors, NIH and MCI remained independently associated (OR = 3.13, 95% CI 1.03-9.53, P = 0.045). BDNF levels were positively correlated with MoCA score (r = 0.169, P = 0.028) and negatively correlated with nocturnal average oxygen saturation in patients with NIH (r = - 0.288, P = 0.008). Older adults with different BDNF Val66Met genotypes did not show significant differences in MCI rate and BDNF levels (P > 0.05). CONCLUSION The older adults with NIH have a higher MCI detection rate. BDNF levels may be a potential biomarker for cognitive dysfunction in patients with NIH.

Abstract
Objective: To investigate the characteristics of nasal flora and the pathogenic role of differential microbiome in patients with allergic rhinitis (AR) and non-allergic rhinitis (nAR). Methods: Thirty-five patients with AR who attended the rhinology outpatient clinic of the Second Hospital of Harbin Medical University from February to July 2022 were selected. A total of 35 nAR patients were selected as the test group, and 20 cases of healthy people with physical examination at the same period were selected as the control group, including 39 males and 51 females, aged 8 to 55 years. 16SrDNA High-throughput sequencing was used to analyze the relative abundance from nasal flora in the three groups of subjects. Alpha diversity index analysis was conducted with R software, and differences between groups were analyzed with LEfSe, Metastats, and t tests. At the same time, the role of microbiome and its relationship with environmental factors were analyzed with R software. Results: There was a significant difference in the bacterial composition of the samples from the three groups, with the relative abundance of Staphylococcus aureus (P=0.032) and Corynebacterium proinquum (P=0.032) within the AR group being significantly higher than that of the nAR group, and that of Lactobacillus murinus, Lactobacillus kunkeei, and Alcaligenes faecalis (P value was 0.016, 0.005, and 0.001, respectively) being significantly lower than that of the nAR group. The relative abundance of Ackermannia muciniphila within the nAR group was higher than that of the control group (P=0.009). Correlation analysis of environmental factors showed a negative correlation between Lactobacillus kunkeei and IgE (P=0.044), and a positive correlation between Lactobacillus murinus and age (P=0.019). AR and nAR random forest prediction models were constructed for the five genera, respectively, and the area under the curve (AUC) of the models of Streptococcus-SP-FF10, Pseudoalteromonas luteoviolacea, Pseudomonas parafulva, Acinetobacter ursingii, and Azotobacter chroococcum in the AR group was 100% (95%CI: 100% to 100%). The AUC for the Pseudomonas parafulva, Azotobacter chroococcum, Closoridium baratii, Turicibacter-SP-H121, and Streptococcus lutetiensis models in the nAR group was 98.4% (95%CI: 94.9% to 100%). Conclusions: The distribution of nasal flora in AR patients, nAR patients and healthy subjects is significantly different, and the changes of bacterial flora abundance are significantly related to the occurrence of AR and nAR. Combined detection of microbiota has the potential to diagnose AR and nAR patients.

Abstract
Objective: To explore a simple and feasible method for the isolation and purification of hepatocytes, hepatic stellate cells (HSC), and lymphocytes from mice. Methods: The cell suspension was obtained from male C57bl/6 mice by hepatic perfusion through the portal vein digestion method and then isolated and purified by discontinuous Percoll gradient centrifugation. Trypan blue exclusion was used to determine cell viability. Glycogen staining, cytokeratin 18, and transmission electron microscopy were used to identify hepatic cells. Immunofluorescence was used to detect α-smooth muscle actin combined with desmin in HSCs. Flow cytometry was used to analyze lymphocyte subsets in the liver. Results: After isolation and purification, about 2.7×10(7) hepatocytes, 5.7×10(5) HSCS, and 4.6×106 hepatic mononuclear cells were obtained from the liver of mice with a body weight of about 22g. The cell survival rate in each group was > 95%. Hepatocytes were apparent in glycogen deposited purple-red granules and cytokeratin 18. Electron microscopy showed that there were abundant organelles in hepatocytes and tight junctions between cells. HSC had expressed α-smooth muscle actin and desmin. Flow cytometry showed hepatic mononuclear cells, including lymphocyte subsets such as CD4, CD8, NKs, and NKTs. Conclusion: The hepatic perfusion through the portal vein digestion method can isolate multiple primary cells from the liver of mice at once and has the features of simplicity and efficiency.

Abstract
Objective: To evaluate the efficiency and safety of collar-button type keratoprosthesis (c-bKPro) implantation for corneal blindness in high-risk transplantation in China. Methods: It was a case series study. High-risk corneal blind patients who planned to undergo c-bKPro implantation were prospectively and continuously enrolled in the Eye Hospital of Shandong First Medical University, Ophthalmology Division of Chinese PLA General Hospital, Zhongshan Ophthalmic Center, Department of Ophthalmology in Eye & ENT Hospital of Fudan University, and Eye Hospital of Wenzhou Medical University from July 2019 to January 2020. The cure for blindness and surgical success were assessed based on visual acuity (VA)≥0.05. The complications and keratoprosthesis retention rate were recorded to determine the safety of the surgery. Results: Thirty-seven subjects (eyes) were included, of which 32 were male and 5 were female, aged 27 to 72 years old. The indications of c-bKPro implantation were corneal graft failure (21 eyes, 56.8%), chemical injury (8 eyes, 21.6%), thermal burn (5 eyes, 13.5%), unexplained corneal opacity (2 eyes, 5.4%), and corneal perforation (1 eye, 2.7%). Two patients withdrew from the clinical trial at 3 months postoperatively. Thirty-five patients were followed up for 6 months, and 31 were followed up for 12 months. The VA was ≥0.05 in 83.8% of eyes at 6 months and in 81.8% of eyes at 12 months. Among the 11 eyes diagnosed with concurrent glaucoma, 6 eyes achieved a VA of ≥0.05. At 12 months, the c-bKPro retention rate was 100%. The surgical complications included retroprosthetic membrane formation (5 eyes, 16.1%), persistent corneal epithelial defects (5 eyes, 16.1%), macular edema (4 eyes, 12.9%), new-onset glaucoma (4 eyes, 12.5%; including one eye withdrawn from the study at 3 months), sterile corneal melting (2 eyes, 6.5%), sterile vitritis (1 eye, 3.2%), and infectious keratitis (1 eye, 3.2%). Conclusions: C-bKPro implantation is an effective and safe option for treating corneal blindness in high-risk transplantation in China. Improved visual outcomes could be achieved in most cases, with a relatively low incidence of postoperative complications.

Abstract
Objective: To investigate the etiology, prevention and treatment status, and their corresponding regional differences of the patients with liver cirrhosis in China, in order to provide scientific basis for the development of diagnosis and control strategies in China. Methods: Clinical data of patients diagnosed with liver cirrhosis for the first time through January 1, 2018 to December 31, 2020 from 50 hospitals in seven different regions of China were collected and analyzed retrospectively, and the difference of etiology, treatment, and their differences in various regions were analyzed. Results: A total of 11 861 cases with liver cirrhosis were included in the study. Thereinto, 5 093 cases (42.94%) were diagnosed as compensated cirrhosis, and 6 768 cases (57.06%) had decompensated cirrhosis. Notably, 8 439 cases (71.15%) were determined as chronic hepatitis B-caused cirrhosis, 1 337 cases (11.27%) were alcoholic liver disease, 963 cases (8.12%) were chronic hepatitis C, 698 cases (5.88%) were autoimmune liver disease, 367 cases (3.09%) were schistosomiasis, 177 cases (1.49%) were nonalcoholic fatty liver, and 743 cases (6.26%) of other types of liver disease. There were significant differences in the incidence of chronic hepatitis B, chronic hepatitis C, alcoholic liver disease, fatty liver, schistosomiasis liver disease, and autoimmune liver disease among the seven regions (P<0.001). Only 1 139 cases (9.60%) underwent endoscopic therapy, thereinto, 718 cases (6.05%) underwent surgical therapy, and 456 cases (3.84%) underwent interventional therapy treatment. In patients with compensated liver cirrhosis, 60 cases (0.51%) underwent non-selective β receptor blockers(NSBB), including 59 cases (0.50%) underwent propranolol and 1 case (0.01%) underwent carvedilol treatment. In patients with decompensated liver cirrhosis, 310 cases (2.61%) underwent NSBB treatment, including 303 cases (2.55%) underwent propranolol treatment and 7 cases (0.06%) underwent carvedilol treatment. Interestingly, there were significant differences in receiving endoscopic therapy, interventional therapy, NSBB therapy, splenectomy and other surgical treatments among the seven regions (P<0.001). Conclusion: Currently, chronic hepatitis B is the main cause (71.15%) of liver cirrhosis in several regions of China, and alcoholic liver disease has become the second cause (11.27%) of liver cirrhosis in China. The three-level prevention and control of cirrhosis in China should be further strengthened.

Abstract
Objective: To explore the characteristics and correlations of vaginal flora in women with cervical lesions. Methods: A total of 132 women, including 41 women diagnosed with normal cervical (NC), 39 patients with low-grade cervical intraepithelial neoplasia (CIN 1), 37 patients with high-grade cervical intraepithelial neoplasia (CIN 2/3) and 15 patients with cervical squamous cell carcinoma (SCC), who came from the gynecological clinic of Second Hospital of Shanxi Medical University during January 2018 to June 2018, were enrolled in this study according to the inclusive and exclusive criteria strictly. The vaginal flora was detected by 16S rDNA sequencing technology. Co-occurrence network analysis was used to investigate the Spearman correlations between different genera of bacteria. Results: The dominant bacteria in NC, CIN 1 and CIN 2/3 groups were Lactobacillus [constituent ratios 79.4% (1 869 598/2 354 098), 63.6% (1 536 466/2 415 100) and 58.3% (1 342 896/2 301 536), respectively], while Peptophilus [20.4% (246 072/1 205 154) ] was the dominant bacteria in SCC group. With the aggravation of cervical lesions, the diversity of vaginal flora gradually increased (Shannon index: F=6.39, P=0.001; Simpson index: F=3.95, P=0.012). During the cervical lesion progress, the ratio of Lactobacillus gradually decreased, the ratio of other anaerobes such as Peptophilus, Sneathia, Prevotella and etc. gradually increased, and the differential bacteria (LDA score >3.5) gradually evolved from Lactobacillus to other anaerobes. The top 10 relative abundance bacteria, spearman correlation coefficient>0.4 and P<0.05 were selected. Co-occurrence network analysis showed that Prevotella, Peptophilus, Porphyrinomonas, Anaerococcus, Sneathia, Atopobium, Gardnerella and Streptococcus were positively correlated in different stages of cervical lesions, while Lactobacillus was negatively correlated with the above anaerobes. It was found that the relationship between vaginal floras in CIN 1 group was the most complex and only Peptophilus was significantly negatively correlated with Lactobacillus in SCC group. Conclusions: The increased diversity and changed correlations between vaginal floras are closely related to cervical lesions. Peptophilus is of great significance in the diagnosis, prediction and early warning of cervical carcinogenesis.

Abstract
Objective: To investigate the roles of N6-methyladenosine (m6A) modification in regulating RP11-426A6.5 in the development of laryngeal squamous cell carcinoma (LSCC). Methods: The methylation and expression levels of lncRNAs were identified and important lncRNAs were screened utilizing long non-coding RNA (lncRNA) m6A methylation microarray. Cancer and para cancer tissue samples were taken from 48 LSCC patients hospitalized to the Department of Otolaryngology-Head and Neck Surgery of the Second Affiliated Hospital of Harbin Medical University between January and September 2017. Expression profiling microarray was performed in 3 of 48 LSCC samples, and methylated RNA immunoprecipitation-quantitative PCR (MeRIP-qPCR) and quantitative real-time fluorescent PCR (qRT-PCR) were performed in the remaining 45 LSCC samples to verify the m6A modification and expression levels of RP11-426A6.5. Correlations between RP11-426A6.5 and clinical factors were anlysed. Laryngeal cancer cell line with low expression of RP11-426A6.5 was created in vitro using RNA interference (RNAi) technology. The 5-Ethynyl-2'-deoxyuridine (EdU) cell proliferation experiment, wound healing experiment, and transwell invasion experiment were used respectively to measure the proliferation, migration, and invasion of LSCC cells. The effect of RP11-426A6.5 down-regulation on the growth of transplanted tumors in vivo was verified by nude mice tumorigenesis assay. The Cancer Genome Atlas (TCGA) database and sequence-based RNA adenosine methylation site predictor (SRAMP) website were used to predict the enzymes and corresponding methylation sites. MazF digestion was chosen to validate the binding sites. RNAi technology was used to observe the changes in cell function after interfering with the expression of the corresponding genes of the modified enzymes. MeRIP-qPCR was used to detect the level of RP11-426A6.5 m6A cell line treated with actinomycin D was used to observe the stability of RP11-426A6.5. Results: RP11-426A6.5 methylation and expression levels were significantly higher in LSCC tissues than those in paracancerous tissues (methylation levels: 23.828±4.975 vs 20.280±3.607; expression levels: 1.197±0.314 vs 1.015±0.170, all P values<0.05). RP11-426A6.5 expression levels were closely correlated with T stage (T1-2: 1.081±0.298 vs T3-4: 1.306±0.292, χ2=5.35, P<0.05). The postoperative survival of patients with high RP11-426A6.5 expressions was significantly lower than that of patients with low RP11-426A6.5 expression (P=0.046). Assays in vitro and in vivo showed that the downregulation of RP11-426A6.5 significantly decreased the proliferation, migration, and invasion abilities of LSCC cells and the growth of transplanted tumors. The binding of methyltransferase-like 3 (METTL3), an m6A-modified enzyme, to the corresponding methylation site of RP11-426A6.5 enhanced its stability and mediated its regulation of malignant behaviors of LSCC cells. Conclusions: RP11-426A6.5 can regulate the malignant behaviors of LSCC cells, which is mediated by the m6A modification process involving in the methyltransferase METTL3.

Abstract
Objective: To investigate the correlation between methylation in human papillomavirus 16 (HPV16) long control region (LCR) and cervical intraepithelial neoplasia grade ≥2 (CIN2+). Methods: The literature retrieval was conducted by using the databases of PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang data and Weipu according to the inclusion and exclusion criteria, and the retrieval period was from the establishment of the databases to February 27th, 2022. Software RevMan 5.3 and Stata 15.1 were used for Meta-analysis. Results: A total of 17 literatures were included involving 1 421 subjects. Results of Meta-analysis showed that OR of the correlation between methylation of HPV16 LCR and CIN2+ was 1.56 (95%CI: 0.70-3.47). Subgroup analysis showed that methylation of the 5' terminal, enhancer and promoter regions were not associated with CIN2+, while in four E2 binding sites (E2BS), the methylation of E2BS1, E2BS3 and E2BS4 increased the risk of CIN2+, with the ORs of 3.92 (95%CI: 1.92-7.99), 10.50 (95%CI: 3.67-30.04) and 3.65 (95%CI: 1.58-8.41), respectively. However, subgroup analysis on E2BS2 was not performed due to the limitation of the number of literatures. According to the different sources of population, the risk of CIN2+ in Chinese population was associated with methylation of HPV16 LCR (OR=2.14, 95%CI: 1.31-3.50). There was a correlation between the risk of CIN2+ and HPV16 LCR methylation in the population with pyrosequencing of HPV16 LCR, and OR was 1.75 (95%CI: 1.03-2.98). Conclusion: The risk of CIN2+ is correlated with the methylation of E2BS in HPV16 LCR, which can be used as potential biomarkers.

Abstract
Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Abstract
Objective: To evaluate the relationship between red blood cell folate (RBC folate) and the prognosis of low-grade cervical intraepithelial neoplasia (CIN 1). Methods: In the married women cohort established in 2014, 564 women with CIN 1 diagnosed by pathology were recruited. The demographic characteristics and factors of cervical intraepithelial neoplasia were collected. Meanwhile, the infection status of human papillomavirus (HPV) was detected by molecular diversion hybridization, and the level of RBC folate was measured by chemical photoimmunoassay. After 24 months of follow-up, pathological examination was performed again to observe the prognosis of participants. The women with reversal were taken as the control group,and those with continuous and progressive CIN 1 were taken as the case group respectively. The relationship between RBC folate and CIN 1 outcome was evaluated by logistic regression model. Results: 453 women completed the follow-up, aged (49.72±6.84) years old. CIN 1 was reversed in 342 women, continued in 58 cases and progressed in 53 cases. The RBC folate level M (Q1,Q3) were 399.01 (307.10, 538.97) ng/ml, 316.98 (184.74, 428.49) ng/ml and 247.14 (170.54, 348.97) ng/ml, respectively. With the decrease of RBC folate, the risk of continuous and progressive CIN 1 increased (all P<0.001), while the risk of reversal CIN 1 decreased gradually (P<0.001). Combined with high-risk human papillomavirus (HR-HPV) infection status, low level of RBC folate could increase the risk of CIN 1 progression regardless of HR-HPV infection (HR-HPV infection: OR=21.34, 95%CI: 3.98-114.54; HR-HPV uninfection: OR=11.15, 95%CI: 2.34-53.13). Conclusion: Low level of RBC folate could increase the risk of CIN 1 persistence and progression regardless of HR-HPV infection.

Abstract
BACKGROUND The CD47-SIRPα pathway acts as an important myeloid cell immune checkpoint and targeting the CD47/SIRPα axis represents a promising strategy to promote antitumor immunity. Several CD47-targeting agents show encouraging early activity in clinical trials. However, due to ubiquitous expression of CD47, the antigen sink and hematologic toxicity, such as anemia and thrombocytopenia, are main problems for developing CD47-targeting therapies. Considering the limited expression of SIRPα, targeting SIRPα is an alternative approach to block the CD47-SIRPα pathway, which may result in differential efficacy and safety profiles. METHODS SIRPα-targeting antibody BR105 was generated by hybridoma fusion and following humanization. BR105 was characterized for binding to human SIRPα alleles and blockade of the interaction with CD47. The functional activity was determined in in vitro phagocytosis assays by using human macrophages. The effect of BR105 on human T cell activation was studied using an OKT3-induced T-cell proliferation assay and an allogeneic mixed lymphocyte reaction. Human SIRPα-humanized immunodeficient mice were used in cancer models for evaluating the in vivo antitumor efficacy of BR105. Safety was addressed in a repeat-dose toxicity study in cynomolgus monkeys, and toxicokinetic analysis was further evaluated. RESULTS BR105 shows broad binding activity across various SIRPα variants, and potently blocks the interaction of SIRPα and CD47. In vitro functional assays demonstrated that BR105 synergizes with therapeutic antibodies to promote phagocytosis of tumor cells. Moreover, the combination of BR105 and therapeutic antibody significantly inhibits tumor growth in a xenograft tumor model. Although BR105 may slightly bind to SIRPγ, it does not inhibit T cell activation, unlike other non-selective SIRPα-targeting antibody and CD47-targeting agents. Toxicity studies in non-human primates show that BR105 is well tolerated with no treatment-related adverse effects noted. CONCLUSIONS The novel and differentiated SIRPα-targeting antibody, BR105, was discovered and displays promising antitumor efficacy in vitro and in vivo. BR105 has a favorable safety profile and shows no adverse effects on T cell functionality. These data support further clinical development of BR105, especially as a therapeutic agent to enhance efficacy when used in combination with tumor-targeting antibodies or antibodies that target other immune checkpoints.

Abstract
Preperimetric glaucoma (PPG) refers to the earliest stage of primary open-angle glaucoma (POAG) before emergence of visual field defects. However, the existence and diagnosis of the PPG stage remains controversial. In this article, with focuses on the clinical significance of intraocular pressure measurements, the etiology classification of POAG, the value of follow-up to PPG diagnosis, the accuracy of devices and methods, and genetic factors of POAG, we point out that PPG should be carefully diagnosed in clinical practice. It is hoped that constant and deep understanding of PPG could help to reach consensus opinions, thus improving and enhancing the diagnosis and treatment of glaucoma.

Abstract
Wernekinck commissure syndrome is a rare midbrain infarction, it consists of several symptoms including bilateral cerebellar ataxia, ophthalmoplegia, and palatal tremor. Holmes tremor is a rare clinical syndrome characterized by a combination of resting, postural, and action tremors. We describe two cases of Wernekinck commissure syndrome with Holmes tremor. To the best of our knowledge, it has been rarely reported in the literature to date. Both of the cases were presented with acute onset of bilateral cerebellar ataxia, dysarthria, and Holmes tremor. In the treatment, one patient was given "clonazepam and benheisol," the other was received acupuncture therapy, both of them showed a marked improvement in ataxia and tremor.

Abstract
Objective: To investigate the effect of red blood cell folate on the prognosis of high-risk human papillomavirus (HR-HPV) infection. Methods: A total of 564 participants with low-grade cervical intraepithelial neoplasias (CINⅠ) were selected from the community-based married women cohort established in 2014. The general baseline information and factors related to HPV infection were collected. Meanwhile, HPV genotyping and levels of folate were measured. The subjects were divided into different levels of exposure group according to the folate levels and followed up for 24 months to observe the changes of HR-HPV infection status. There were four changes, including persistent infection, infection turned negative, from negative to positive and constant negative by comparing HR-HPV infection status at baseline and follow-up to 24 months. Results: 483 participators completed 24 months of follow-up observation, with a follow-up rate of 85.64% (483/564). The rates of persistent infection, infection turned negative, from negative to positive, and the constant negative were 52.45% (75/143), 47.55% (68/143), 19.71% (67/340), 80.29% (273/340), respectively. Our results demonstrated that the risk of persistent infection (aRR=2.50, 95%CI: 1.55-4.02) and from negative to positive (aRR=4.55, 95%CI: 2.52-8.23) in the low level of folate were significantly higher than that in the high level of folate, especially the risk of homotype persistent infection (aRR=2.72, 95%CI: 1.51-4.90). The risk of persistent infection (trend χ2=20.62, P<0.001), from negative to positive (trend χ2=31.76, P<0.001), persistent homotypic infection (trend χ2=20.09, P<0.001) increased with the decrease of red blood cell folate level. On the contrary, no similar results were found in persistent heterotypic infection. Conclusions: A low level of red blood cell folate could increase the risk of HR-HPV persistent infection and from negative to positive. In women with HR-HPV infection, the risk of persistent homotypic infection is higher.

Abstract
HS002 is the recombinant human tumor necrosis factor-α receptor Ⅱ: IgG Fc fusion protein licensed in China to treat rheumatism and psoriasis. The aim of this study was to isolate and characterize the hydrophobic freeze-dried powder injection (HS002) and ampoule injection (HS002A) variants derived from proteins of the same sequence and then to explore the structure-function relationship. Extensive physicochemical and structural testing was performed during a side-by-side comparison of the monomer peak and variant. Then the TNF-α-related binding activity, cell biological activity and affinity with FcRn were analyzed. Finally, a transformation study of the hydrophobic variant was performed under serum-like redox conditions. This research revealed that HS002A has similar physicochemical and structure-function relationship profiles to those of HS002. The hydrophobic variant exhibited the presence of new incorrect disulfide bridging. At the same time, this novel disulfide scrambled species structure-function relationship was found to be the molecular basis for reduced TNF-α binding and cell biological activities. In addition, incorrect disulfide bridging was found to be reversible under serum-like redox conditions, restoring TNF-α binding and cell biological activities to almost normal levels, all of which indicate that the variant is probably irrelevant to clinical efficacy once the drug enters the bloodstream.

Abstract
Objective: To investigate the effects of polycyclic aromatic hydrocarbons (PAHs) exposure on the prognosis of high risk human papillomavirus (HR-HPV) infection. Methods: In this prospective study, 564 patients with low-grade cervical intraepithelial neoplasia confirmed by pathology were selected from the natural cohort population established by our research group in Shanxi province in 2014. Based on the baseline data of demographic characteristics and factors related to HPV infection, the concentrations of 1-hydroxypyrene in urine samples of the patients were determined by high performance liquid chromatography to define the exposure level of PAHs. At baseline survey and follow-up after 24 months, flow-through hybridization was used to detect HPV infection types, and to evaluate the prognosis of HR-HPV (persistent infection, negative conversion, positive conversion and persistent negative status). Results: Of the 564 subjects, 483 completed the follow-up, with a follow-up rate of 85.6% (483/564). Among them, the persistent infection rate was 52.4% (75/143), the persistent homotype infection rate was 35.7% (51/143), the negative conversion rate was 47.6% (68/143), the positive conversion rate was 19.7% (67/340), and the persistent negative rate was 80.3% (273/340). The follow-up results showed that the persistent infection rate (aRR=3.22, 95%CI: 1.85-5.62) and positive conversion rate (aRR=2.84, 95%CI: 1.64-4.94) of HR-HPV in high PAHs exposure group were higher than those in low PAHs exposure group, while the persistent negative rate (aRR=0.55, 95% CI: 0.43-0.70) of HR-HPV in high PAHs exposure group were lower than those in low PAHs exposure group. Based on restrictive cubic spline analysis, the results showed that the effects of PAHs exposure on persistent HR-HPV infection and persistent homotype infection showed an ascending linear dose-response relationship, while on HR-HPV positive conversion and persistent negative status showed an ascending and declining nonlinear dose-response relationship respectively (P<0.01). Conclusions: High PAHs exposure could promote persistent HR-HPV infection and persistent homotypic infection. Reducing PAHs exposure might conducive to HR-HPV continuous negative maintenance. Active prevention and control of PAHs exposure is of great significance to prevent HR-HPV infection and persistent infection.

Abstract
Objective: To evaluate the relationship between serum folate and the prognosis of cervical intraepithelial neoplasia grade I (CIN1) and the interaction between folate and high risk human papillomavirus (HR-HPV) infection. Methods: From a community-based married women cohort established in Jiexiu and Yangqu County of Shanxi Province from June to December 2014, a total of 564 eligible women with CIN1 by pathologically diagnosed were recruited. The pathological examination was performed again 12 months later. According to the prognosis of CIN1, participants were divided into CIN1 regression group, persistence and progression group, respectively. Nested case-control study was used to explore the relationship between serum folate and CIN1 prognosis, and additive model was used to analyze the interaction between serum folate and HR-HPV infection. Results: Among 564 CIN1 patients, 479 cases underwent pathological examination again, 331 were divided in CIN1 regression group and other 148 in persistence and progression group. The levels of serum folate in CIN1 regression group and persistence and progression group were (18.890±8.360) and (15.640±5.550) nmol/L, respectively, and the difference was statistically significant (Z=-6.937, P<0.001). HPV infection was detected in 154 patients, including 148 cases of HR-HPV infection and 6 cases of low risk human papillomavirus (LR-HPV) infection. Univariate analysis showed that there were significant differences in the age, passive smoking, frequency of pudendal cleaning, frequency of cleaning after sex, frequency of changing underwear, serum folate and HR-HPV infection between regression group and persistence and progression group (P<0.05). Multivariate logistic regression analysis showed that the frequency of pudendal cleaning (OR=0.422, 95%CI: 0.238-0.750), frequency of changing underwear (OR=0.574, 95%CI: 0.355-0.928), serum folate (13.06-16.78nmol/L: OR=4.806, 95%CI: 2.355-9.810; ≤13.05nmol/L: OR=8.378, 95%CI: 4.024-17.445), HR-HPV infection (OR=1.852, 95%CI: 1.170-2.933) were the independent influencing factors of CIN1 prognosis. Interaction analysis showed that the relative excess risk of low serum folate level and HR-HPV infection for the CIN1 persistence and progression was 4.992 (95%CI: 0.189-9.796), attributable proportion due to interaction was 0.552 (95%CI: 0.279-0.824), synergy index was 2.632 (95%CI: 1.239-5.588), aOR of serum folate≤16.78 nmol/L and HR-HPV infection positive was 9.055 (95%CI: 4.878-16.807). Conclusion: Low serum folate level could increase the risk of CIN1 persistence and progression, and might enhance the risk when combined with HR-HPV infection.

Abstract
Objective: To explore the role and mechanism of long non-coding RNA RP11-159K7.2 in the progression of sinonasal squamous cell carcinoma (SNSCC). Methods: Sixty-five cases of SNSCC tissues and adjacent tissues were selected from the Department of Otorhinolaryngology Head and Neck Surgery, the Second Affiliated Hospital of Harbin Medical University from 2009 to 2014. The expression of RP11-159K7.2 in SNSCC and adjacent tissues was detected by RNAscope in situ hybridization to observe its association with prognosis. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated proteins 9 (CRISPR/Cas9) was used to knockout the expression of RP11-159K7.2 in RPMI-2650 cells (SNSCC cell line). Cell counting kit-8 (CCK-8), wound healing and Transwell were performed to observe the changes of proliferation, migration and invasion of SNSCC cells in vitro after down-regulation of RP11-159K7.2. Moreover, the growth of xenograft in nude mice after down-regulation of RP11-159K7.2 was examined in vivo. Mechanically, the protein chip, Western blot and RNA immunoprecipitation were performed to identify the proteins bound by RP11-159K7.2. SPSS 17.0 was used for statistical analysis. Results: The expression of RP11-159K7.2 in SNSCC tissue was significantly higher than that in adjacent tissues. RP11-159K7.2 expression was closely related with T grade, nodal metastasis and differentiation of SNSCC (χ2 value was 4.697, 4.235 and 10.753, respectively, all P<0.05). The five-year survival rate of RP11-159K7.2 high expression patients was significantly lower than that of RP11-159K7.2 low expression ones (P=0.013 7). After the down-regulation of RP11-159K7.2, the proliferation, migration and invasion ability of SNSCC cells decreased significantly, and the growth of SNSCC xenograft was significantly inhibited. There were 31 candidate proteins that may bind to RP11-159K7.2. RP11-159K7.2 directly bound to nuclear factor-κB (NF-κB) in SNSCC cells, and the regulation of RP11-159K7.2 on the proliferation and invasion of SNSCC cells depended on NF-κB. Conclusion: The increased expression of RP11-159K7.2 in SNSCC may serve as a potential molecular marker for SNSCC prognosis assessment. It is currently considered that the carcinogenic mechanism of RP11-159K7.2 in SNSCC is related to the regulation of NF-κB protein.

Abstract
Objective: To explore the effect of dietary water-soluble vitamins on the poor prognosis of low-grade cervical intraepithelial neoplasia (CINⅠ). Methods: A total of 564 participants with CINⅠ were selected from a community-based married women cohort established in 2014. The general baseline information was collected, and HPV genotyping was detected. A food frequency questionnaire was used to investigate dietary water-soluble vitamins' consumption and determine their exposure levels. The follow-up program was carried out for 12 months, and the regression, persistence, and progression of CINⅠ was determined according to histopathological results at 12-month. Results: The low-levels of dietary water-soluble vitamins could promote CINⅠ's persistence and progression, showing the increasing tendency of CINⅠ poor prognosis with the decrease of water-soluble vitamin levels. Especially folate, VB1, VB2, VB6, niacin, biotin, and VC (RR values were 15.22, 1.86, 1.92, 2.11, 2.98, 2.14, 2.19, respectively) played an important role. Considering the status of high-risk human papillomavirus (HR-HPV) infection, our results showed that the low levels of folate, niacin, biotin could promote the poor prognosis of CINⅠ. Conclusions: The low-level of dietary water-soluble vitamins could facilitate the poor prognosis of CINⅠ. In addition, folate, niacin, biotin were more effective on HR-HPV positive women.

Abstract
Objective: To investigate the diagnostic value of different vaginal micro-environmental factors in low-grade cervical intraepithelial neoplasia (CIN Ⅰ) and determine the optimal model in high-risk human papillomavirus (HR-HPV) infection. Methods: A total of 926 women, including 623 with normal cervical (NC) condition and 303 CINⅠ patients, had undergone pathological examinations, and were enrolled in the study. All the women were from a community previously established cohort. Vaginal cleanliness, pH, H2O2, β-glucuronidase, coagulase, sialidase, and leukocyte esterase (LE) were detected by the combined detection method aerobic vaginitis/bacterial vaginosis in vaginal secretions. HPV genotyping was performed by using the flow-through hybridization technology. The data were analyzed by SAS 9.2 and SPSS 23.0. Results: The vaginal cleanliness, pH, sialidase, and LE were determined as the representative vaginal micro-environment factors by principal component analysis. Based on logistic regression theory to analyze the ROC curve, the results showed that the highest sensitivity was with pH value (76.2%), and the highest specificity was with sialidase (90.9%). The area under ROC curve were higher in combination detection modes of sialidase+LE (0.714), pH+sialidase+LE (0.719), vaginal cleanness+sialidase+LE (0.713) and pH+vaginal cleanness+sialidase+LE (0.709). According to HR-HPV infection status, the TOPSIS method was used to analyze the combined detection optimal model. Specifically, we found that the best diagnostic model was pH+sialidase +LE (Ci=0.585) in the HR-HPV positive group and vaginal cleanness+sialidase+LE (Ci=0.641) in the negative group. Conclusions: The combined detection of vaginal microenvironment factors could be used for auxiliary diagnosis for CINⅠ. It would be more effective when detecting pH, sialidase, and LE in HR-HPV positive women while vaginal cleanness, sialidase, and LE in HR-HPV negative women at the same time.

Abstract
Objective: To describe the characteristics of high-risk human papillomavirus (HR-HPV) infection and its influences by vaginal micro-environmental factors. Methods: A total of 421 women with HR-HPV infection and normal cervix diagnosed by pathology were selected from a community cohort established earlier by our research group for a 24-month follow-up. The baseline data were collected at enrollment. The vaginal micro-environmental factors were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. And the HPV was detected by using the flow-through hybridization technology. According to the HR-HPV infection status in baseline and 24 months of follow-up, with the prognosis characteristics of HR-HPV infection described, the impact of vaginal micro-environmental factors on the prognosis of HR-HPV infection was explored as well. Results: Among 390 HR-HPV infected women who completed 24 months of follow-up, the top five types of persistent HR-HPV infection rate appeared as HPV16 (24.1%), HPV58 (22.2%), HPV53 (21.7%), HPV52 (20.0%), and HPV39 (11.8%), respectively. The results showed that women with abnormal vaginal pH (aOR=1.74, 95%CI: 1.08-2.80), abnormal neuraminidase (aOR=2.70, 95%CI: 1.52-4.83), or abnormal leucocyte esterase (aOR=3.41, 95%CI: 2.13-5.44), the risk of HR-HPV persistent infection increased. The abnormalities of neuraminidase and leukocyte esterase could increase the risk of persistent infection of homotype and heterotypic HR-HPV. Conclusions: HPV16 was prone to persistent infection. Abnormalities of vaginal pH, neuraminidase, and leukocyte esterase might increase the risk of HR-HPV persistent infection. Both the abnormalities of neuraminidase and leukocyte esterase play an essential role in the HR-HPV persistent infection.

Abstract
Recent research showed that plant secondary metabolites in pollen may exacerbate the protein-mediated allergic reaction in pollen allergy. It was found that allergenic pollen from various plant families contain significant amounts of electrophiles which may covalently bind to nucleophilic groups of proteins, such as thiol moieties. Electrophiles in pollen of the Asteraceae species are typically sesquiterpene lactones, but the nature of electrophilic metabolites in allergenic pollen of other plant families is unknown. We developed a solid-supported cysteinyl probe in order to selectively extract physiologically relevant electrophiles from pollen extracts, and to enable their subsequent characterization by on-line and off-line spectroscopic analysis. The validity of this approach was evaluated with a selection of structurally different model compounds and with a spiked model extract.

Abstract
Objective: To explore the effects of hnRNP E1 on the expression of early genes E2, E6 of HPV16 and the biological function in cervical cancer SiHa cell lines. Methods: The cell experiments in vitro were carried out in cervical cancer cell lines SiHa. The expression levels of E2, E6 mRNA and protein of HPV16 were detected by Real-time PCR and Western blot, respectively, before and after up-regulating hnRNP E1. Meanwhile, the cell proliferation, cycle and apoptosis were evaluated by CCK-8 and flow cytometry. Data analyses were performed using SPSS 22.0 and Graphpad Prism 7.0 software. Results: Compared with the blank and the blank plasmid group, the cells activity and proliferation decreased at 24, 48 and 72 h after up-regulating hnRNP E1 (P<0.05), while the percentage of cells in G0/G1 phase increased and the percentage in S and G2/M phase and proliferation index decreased (P<0.05). Moreover, the late apoptotic rate and the total apoptotic rate increased (P<0.05). The expression levels of E6 mRNA and protein of HPV16 in hnRNP E1 up-regulated group were significantly lower than that in both blank group and blank plasmid group, the differences were significant (P<0.05), showing the tendency of cells proliferation index decrease and total apoptotic rate increase with decreased HPV16 E6 expression. There were no significant differences in the expression of E2 mRNA of HPV16 among the three groups (P=0.427), and no E2 protein of HPV16 was detected. Conclusions: hnRNP E1 could inhibit the transcription and translation of E6 oncogene of HPV16 and further inhibit the proliferation and promote apoptosis of cervical cancer cells, suggesting that hnRNP E1 might be a potential target marker to prevent cervical lesions. But no association between hnRNP E1 and HPV16 E2 was found in SiHa cells.

Abstract
Objective: To study the relations of human papillomavirus (HPV) infection, vaginal micro-environmental disorder with cervical lesion. Methods: A total of 1 019 women including 623 with normal cervical (NC), 303 with low-grade cervical lesion (CIN Ⅰ) and 93 with high-grade cervical lesion (CIN Ⅱ/Ⅲ) were enrolled in this study from the communities in Shanxi province, China. Case-control method was adopted, with NC as the control group and CIN as the case group. Related information was collected including demographic characteristics and relevant factors related to cervical lesions. HPV genotypes were detected by flow-through hybridization technology. Vaginal pH was detected by the pH test paper. Vaginal H(2)O(2) was detected by the combined detection kit of aerobic vaginitis and bacterial vaginosis. Vaginal cleanliness was detected by smear method. Results: Data from the unconditional logistic regression analysis showed that HPV infection (CINⅠ: aOR=1.39, 95%CI: 1.01-1.90; CINⅡ/Ⅲ: aOR=11.74, 95%CI: 6.96-19.80), H(2)O(2) (CINⅠ: aOR=2.09, 95%CI: 1.47-2.98; CINⅡ/Ⅲ: aOR=4.12, 95%CI: 2.01-8.43), cleanliness (CIN Ⅱ/Ⅲ: aOR=2.62, 95%CI: 1.65-4.14), and composite indicators (CINⅠ: aOR=1.67, 95%CI: 1.24-2.25; CINⅡ/Ⅲ: aOR=4.24, 95%CI: 2.30-7.81) all had increased the risk of cervical lesion and the trend on the severity (P<0.001) of cervical lesions. Additionally, we observed a synergic effect between HPV infection and vaginal micro-environmental composite indicator in CINⅡ/Ⅲ. With or without HPV infection, the ORs value of CINⅠ caused by vaginal micro-environment disorder remained close. Conclusions: Results from our study revealed that vaginal micro-environmental composite indicator could increase the risk for cervical lesion, in particular with the high-grade ones which all posed stronger risks when combined with HPV infection. However, the role of vaginal micro-environment disorder in the occurrence of CIN Ⅰ should not be ignored.

Abstract
Objective: To investigate and analyze the current situation, screening, clinical characteristics, prevention and treatment of bleeding esophageal varices in cirrhotic patients with portal hypertension in Tibet region. Methods: Clinical data of cirrhotic patients with portal hypertension through March 2017 to February 2020 from Tibet region were collected and analyzed retrospectively. Results: 511 cases with liver cirrhosis were included in the study, of which 185 cases (36.20%) had compensated cirrhosis and 326 cases (63.80%) had decompensated cirrhosis. Further analysis of the etiological data of liver cirrhosis showed that 306 cases (59.88%) were of chronic hepatitis B, 113 cases (22.11%) of alcoholic liver disease, and 68 cases (13.31%) of chronic hepatitis B combined with alcoholic liver disease. Among patients with compensated liver cirrhosis, 48 cases (25.95%) underwent endoscopic examination of which 33 diagnosed as high-risk variceal bleeding. However, none of these 33 cases had received non-selective β-blocker therapy, and only four patients had received endoscopic variceal banding therapy. Among patients with decompensated liver cirrhosis, 83 cases (25.46%) had a history of upper gastrointestinal bleeding, 297 cases (91.10%) had ascites, 23 cases (7.05%) had hepatic encephalopathy, and 3 cases (0.92%) had hepatorenal syndrome. Among the patients with a history of upper gastrointestinal bleeding, 42 cases (50.60%) had received secondary preventive treatment for bleeding esophageal varices, including 39 cases of endoscopic treatment, 1 case of endoscopic combined drug treatment, 3 cases of interventional treatment, and 2 cases of surgical treatment. Conclusion: Chronic hepatitis B and alcoholic liver diseases are the main causes of liver cirrhosis in Tibet region. Moreover, this region lacks screening, prevention and treatment for bleeding esophageal varices in cirrhotic patients with portal hypertension. Therefore, it is necessary to increase the screening of high-risk groups to prevent and improve the first-time bleeding, and promote multidisciplinary team to prevent and treat re-bleeding.

Abstract
Objective: To explore the short-term effects of ambient PM2.5 on the outpatient visits of allergic conjunctivitis among children in Shenzhen. Methods: It was a ecological study. Data on daily visits including date of visit, sex and age from children with allergic conjunctivitis were collected from Shenzhen Eye Hospital and Shenzhen Children's Hospital in 2018. Related data on air pollution (PM2.5, PM10, SO2, NO2, CO and O3) and meteorology (atmospheric pressure, temperature and relative humidity) were also collected. Pearson correlation analysis was used for normal distribution data and Spearman rank correlation analysis was used for non-normal distribution data. Generalized additive model was used to estimate the impact of PM2.5 pollution on allergic conjunctivitis outpatients and the lagging effects. Results: In 2018, there were 16 133 allergic conjunctivitis outpatients in the two hospitals. The maximum age was 18 years and the minimum age was 2 months. Males accounted for 49.3%. The daily average concentration of PM2.5 was 22 (15, 31) μg/m3. Changes of the concentration of PM2.5 had a positive correlation with the amount of allergic conjunctivitis visits, and the Spearman correlation coefficient was 0.150 (P=0.004). The single pollutant model showed that the strongest effect appeared at 3 days (RR=1.111, 95%CI:1.071-1.152). A 10 μg/m3 increase of PM2.5 would result in an excessive number of allergic conjunctivitis outpatients as much as 11.112% (95%CI:7.011%-15.212%). In the multiple air pollutants models, after the introduction of NO2, O3 and CO, the concentration of PM2.5 showed an enhanced effect on the number of hospital visits due to allergic conjunctivitis on the same day, and the difference was statistically significant (P<0.05). Conclusion: Changes of the concentration of PM2.5 had a positive correlation with daily outpatient visits of allergic conjunctivitis among children in Shenzhen.

Abstract
Objective: To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage. Methods: Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate. Results: 32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34 ~ 21.15) μmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31 ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) μmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) μmol/L, respectively. Conclusion: The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.

Abstract
Objective: To investigate the role of human papillomavirus (HPV) 16 early genes E2 and E6 and heterogeneous nuclear ribonucleoprotein (hnRNP) E2 and their interaction effects in the progression of the cervical cancer. Methods: Women with normal cervix (NC), low cervical intraepithelial neoplasia (CIN Ⅰ) and high cervical intraepithelial neoplasia (CIN Ⅱ/Ⅲ) from the cervical lesions cohort in Jiexiu County of Shanxi Province from June 2014 to September 2014, and patients with cervical squamous cell carcinoma (SCC) treated at the Second Hospital of Shanxi Medical University in the same period were enrolled in this study. There were 257 participants, about 67 NC cases (26.07%), 69 CIN Ⅰ cases (26.85%), 68 CIN Ⅱ/Ⅲ cases (26.46%), and 53 SCC cases (20.62%), respectively. The information of demographic characteristics, life health habits and cervical lesions were collected by using the structured questionnaire. Cervical exfoliated cells and cervical biopsy tissues were collected to detect the infection of HPV16 and the protein expression levels of hnRNP E2, HPV16 E2 and E6. According to the median-value of the protein expression levels of hnRNP E2, HPV16 E2 and E6 and E2/E6 ratio in the NC group, the study participants were divided into the high and low expression groups/ratio groups. The multivariate logistic regression model was used to analyze the correlation between HPV16 early gene E2 and E6, hnRNP E2 and cervical cancer. The interaction effect was analyzed by using the generalized multifactor dimensionality reduction (GMDR) model. Results: The ages of NC, CIN Ⅰ, CIN Ⅱ/Ⅲ and SCC groups were (47.00±9.07), (47.64±7.35), (46.37±8.67) and (51.26±8.03) years old, respectively. The multivariate logistic regression model analysis showed that the HPV16 E2 low expression, E6 high expression and E2/E6 low ratio could increase the risk of CIN Ⅱ/Ⅲ, about OR (95%CI) values 11.11 (1.63-75.56), 8.00 (1.28-50.04), and 9.75 (1.22-77.72), respectively and SCC, about OR (95%CI) values 14.22 (2.11-95.88), 10.33 (1.67-64.00), and 12.38 (1.56-97.91), respectively. The hnRNP E2 low expression could increase the risk of CIN Ⅱ/Ⅲ and SCC, about OR (95%CI) values 3.35 (1.39-8.10) and 5.53 (1.54-19.88). The result of GMDR showed that there were interaction effects of the hnRNP E2 low expression, HPV16 E2 low expression and HPV16 E6 high expression in both CIN Ⅱ/Ⅲ and SCC groups. Conclusion: The HPV16 E2 low expression, HPV16 E6 high expression and hnRNP E2 low expression could increase the risk of high-grade cervical intraepithelial neoplasia and cervical cancer, and they might have an important interaction effect in the progression of the cervical cancer.

Abstract
Objective: To investigate the expression of microRNA-1 (miR-1) and its regulatory function on fibronectin (FN) in human trabecular meshwork cells (HTMC) under oxidative stress. Methods: Experimental study. After HTMC were treated with 0, 60, 100, 200, 400 μmol/L hydrogen peroxide (H(2)O(2)) for 6 h, respectively, the cells were placed in culture medium for 24 h. The expression of miR-1 and FN mRNA in these cells were detected by real-time quantitative PCR. According to bioinformatics analysis, the target gene of miR-1 is predicted to be FN; pcDNA3/pri-miR-1 vectors, pcDNA3/enhanced green fluorescent protein (EGFP)-FN-3'UTR vectors and pcDNA3/EGFP-FN-3'UTRmut vectors were constructed. pcDNA3/pri-miR-1 were co-transfected with pcDNA3/EGFP-FN-3'UTR or pcDNA3/EGFP-FN-3'UTRmut respectively into HTMC. pDsRed2-N1 was taken as internal reference. After 48 h transfection, the absorbance of EGFP and red fluorescent protein (REP) was detected with fluorescence spectrophotometer to explore the effect of miR-1 on FN expression. HTMC was stimulated with 200 μmol/L H(2)O(2) for 24 h after overexpression plasmid of miR-1 was transfected into it, and then FN mRNA and protein levels were detected via real time PCR, Western blotting and immunofluorescence. Data were analyzed via one-way analysis of variance or t test. Results: With the increase of H(2)O(2) concentration, miR-1 decreased (F=390.80, P<0.01) while FN increased (F=13.16, P<0.01). The level of miR-1 in HTMC stimulated by 200 μmol/L and 400 μmol/L H(2)O(2) decreased to 0.608±0.014 (t=21.67, P<0.01) and 0.409±0.020 (t=29.91, P<0.01), respectively, compared with untreated control cells (1.000); whereas, the mRNA levels of FN increased to 1.630±0.233 (t=4.47, P=0.011) and 1.903±0.246 (t=6.15, P=0.003), respectively, compared with untreated control cells(1.000). Through bioinformatics analysis, miR-1 might have candidate binding site in FN mRNA 3'-UTR. Meanwhile, these cells co-transfected with pcDNA3/pri-miR-1 and pcDNA3/EGFP-FN-3'UTRmut (0.562±0.018) had higher EGFP expression than cells co-transfected with pcDNA3/pri-miR-1 and pcDNA3/EGFP-FN-3'UTR (0.329±0.015) (t=17.39, P<0.01). Compared with the control (1.000), after overexpressing miR-1 the mRNA expression and the protein level of FN decreased to 0.294±0.081 (t=11.01, P<0.01) and 0.584±0.022 (t=5.57, P<0.01), respectively. Conclusions: MiR-1 decreases while FN increased in HTMC under oxidative stress. MiR-1 inhibits FN expression through targeting FN 3'-UTR. (Chin J Ophthalmol, 2019, 55: 355-360).

Abstract
Objective: To screen the risk factors of patients with frequent acute exacerbation of chronic obstructive pulmonary disease (COPD) by detecting the clinical indicators of periodontitis and the level of bacterial and inflammatory markers in saliva. Methods: Thirty-eight COPD patients in their stable period were recruited and detected from Beijing Chao-Yang Hospital,Capital Medical University during December 2016 to May 2017. The periodontal index were recorded. The levels of inflammatory factors in saliva samples were examined by using enzyme linked immunosorbent assay (ELISA). The bacteria composition in the saliva samples were identified by using 16SrRNA gene pyrosequencing. All patients were followed up and monitored for acute exacerbation of COPD for 12 months. The patients were divided into frequent acute exacerbation group (≥2 times/year, n=10) and non frequent acute exacerbation group (<2 times/year, n=28). Results: In univariate analysis, the patients' average age of frequent acute exacerbation group (69.0±7.3) was significantly older than that of non-frequent acute exacerbation group (61.8±8.3) (P=0.02). The numbers of remaining teeth ≤26 [100% (10/10)] was significantly higher and plaque index ≤2.5 (2/10) in frequent acute exacerbation group was significantly lower compared with the remaining teeth ≤26 [43% (12/28)] and the plaque index ≤2.5 [71% (21/28)] in non-frequent acute exacerbation group (P=0.02, P=0.01). The proportions of salivary inflammatory factors interleukin-6 (IL-6) level ≤60 ng/L (10%),C-reactive protein (CRP) level ≤1 550 μg/L (30%), matrix metalloproteinase-8 (MMP-8) level ≤140 μg/L (30%) and fibrinogen level ≤90 mg/L (30%) in frequent acute exacerbation group were significantly lower compared with salivary inflammatory factors IL-6 level ≤60 ng/L (71%),CRP level ≤1 550 μg/L (71%), MMP-8 level ≤140 μg/L (86%) and fibrinogen level ≤90 mg/L (71%) in non-frequent acute exacerbation group (P<0.05). The differences of relative abundances of salivary bacteria,such as species of Chloroflexi, Anaerolineae, Anaeroales, Corynebacteriales, Anaerolineaceae, Tissierellaceae, Leptotrichiaceae, Corynebacteriaceae, Leptotrichia, Moryella, Lachnoanaerobaculum and Corynebacterium between frequent acute exacerbation group and non-frequent acute exacerbation group were significantly different (P<0.05). In multivariate logistics regression analysis,the level of IL-6 >60 ng/L and the relative abundance of Corynebacteriales >0.2 had significant difference (P<0.05). Conclusions: The level of IL-6 and the relative abundance of Corynebacteriales might be the markers of frequent acute exacerbation in COPD patients.

Abstract
Objective: This study aimed to assess the prevalence and factors associated with pelvic organ prolapse (POP) in a representative sample of Chinese urban women. Methods: A total of 29613 Chinese urban women were recruited to this cross-sectional study between February 2014 and March 2016. The prevalence of POP, defined as any stage Ⅱ or higher POP resulting in symptoms, was assessed using questionnaires and physical examinations. Multivariable logistic regression was used to assess factors associated with POP. Results: 2 864 of 29 613 women (9.67%) had POP. The prevalence of POP increased with age ranging from 1.23% (82/6 646) of women aged between 20 and 29 years to 26.11% (727/2 784) for those aged 70 years or older (P<0.000 1). Overweight and obese women were more likely to have POP than normal weight women [AOR=1.56, 95%CI 1.42-1.72 vs AOR=1.74, 95%CI 1.48-2.03]. In the multivariate analysis, the independent risk factors were cough (AOR=1.70, 95%CI 1.44-2.02), constipation (AOR=2.05, 95%CI 1.82-2.32), physical disease (AOR=1.27, 95%CI 1.15-1.41), and gynecological diseases (AOR=2.08, 95%CI 1.89-2.29). Nulliparous (AOR=0.12, 95%CI 0.06-0.22) and caesarean section (CS) (AOR=0.55, 95%CI 0.47-0.64) were protective factors for POP. Conclusions: POP affects nearly 10% of women in Chinese urban region. The prevalence of POP increases significantly with age. The independent risk factors for POP are body mass index, cough, constipation, physical disease and gynecological diseases. Nulliparous and CS are protective factors for POP.

Abstract
Objective: To modify Western Ontario and McMaster University Osteoarthritis Index (WOMAC) for more accurate evaluation of patients with knee osteoarthritis in China,and its reliability and validity were measured. Methods: The WOMAC was modified through reviewing relevant literatures and practical survey.Total of 120 patients were enrolled in this study. The subjects completed the WOMAC,the modified WOMAC and Medical Outcomes Study 36-item Short Form(SF-36), and 113 of the questionnaires were valid for analysis [27 males (23.9%), 86 females (76.1%), aged (59±10) years]. Intraclass correlation coefficient and Cronbach α reliability coefficient were used to analyze the modified WOMAC's reliability; exploratory factor analysis was adopted to analyze the validity of WOMAC and the modified WOMAC; Spearman rank correlation coefficient was used to make a correlation analysis among SF-36, WOMAC and the modified WOMAC. Results: For the four dimensions: pain, stiffness, function and life quality in the modified WOMAC, the intraclass correlation coefficient values were 0.861-0.910 and Cronbach α values were 0.751-0.936. In the content validity analysis, the number of extracted common factors for the four dimensions: pain,stiffness,function and life quality in the modified WOMAC were 1,1,2 and 1 respectively. The total variance interpretation rate was 65.684%, 84.367%, 67.252% and 67.572%, respectively. In the construct validity analysis, 4 common factors were extracted for WOMAC and the modified WOMAC respectively. The total variance interpretation rate was 70.100% and 67.213%, respectively. Both WOMAC and the modified WOMAC had a significant correlation with SF-36. Conclusion: The modified WOMAC is more suitable for Chinese living habits, but it still needs to be further evaluated with larger samples.

Abstract
Objective: To explore the effects of hnRNP E1 and both early genes E2 and E6 of HPV16 as well as their interactions in the progression of cervical carcinogenesis. Methods: Subjects of this study included 56 women with normal cervix (NC), 58 patients with low-grade cervical intraepithelial neoplasm (CINⅠ) and 50 patients with high-grade cervical intraepithelial neoplasm (CINⅡ/Ⅲ) who were all recruited from the 'Cervical Lesions Study Cohort Project' in Jiexiu of Shanxi province from June to September, 2014. Another 40 patients with cervical squamous cell carcinoma (SCC) were from the Shanxi Tumor Hospital during the same period. Information related to cervical lesions were collected, using a structured questionnaire, with cervical tissues and cervical exfoliated cells gathered from all the participants. HPV infection was detected by flow-through hybridization, while the levels of expression on hnRNP E1, HPV16 E2 and E6 protein were measured by Western Blot. Kruskal-Wallis H test, χ(2) test, trend χ(2) test were analyzed by SPSS 22.0 software, while interaction was evaluated by generalized multifactor dimensionality reduction (GMDR). Results: The overall infection rates of HPV16 related to CINⅠ (15.52%, 9/58), CINⅡ/Ⅲ (40.00%, 20/50) and SCC (67.50%, 27/40) groups were all higher than that of the NC group (8.93%, 5/56) and with an increasing trend on the severity of cervical lesions (trend χ(2)=43.613, P<0.001). The levels of expression on hnRNP E1 protein were significantly different in the groups with different cervical lesions (H=9.98, P=0.019), showing a decreasing trend with the severity of cervical lesions (trend χ(2)=9.495, P=0.002). The levels of expression on HPV16 E2 (H=16.20, P=0.001) and HPV16 E6 (H=15.44, P=0.001) were significantly different in groups with different cervical lesions. Results of GMDR showed that the best interaction model in both groups of CINⅡ/Ⅲ and SCC appeared as hnRNP E1 low expression, HPV16 E2 low expression and HPV16 E6 high expression. However, no similar interaction was seen in CINⅠ (P>0.05). Conclusions: Both low expressions of hnRNP E1 and abnormal expression of HPV16 E2 and E6 could increase the risk of high-grade CIN and cervical cancer. It seemed that they might have an important synergistic effect on the progression of cervical cancer.

Abstract
Objective: To explore the effect of Src on cervical cancer cells through ERK signal transduction pathway. Methods: Experimental study was carried out in vitro. Cervical cancer cell lines Hela (HPV-positive) and C33A (HPV-negative) were treated with Src kinase inhibitor PP2. Then, the cell cycle and apoptosis of each group were evaluated by using flow cytometry (FCM). Western blotting and Real-time PCR were used to detect the levels of the expression of ERK 1/2, c-Fos and c-Jun mRNA and protein respectively. The database was established and analyzed with SPSS statistical software (version 20.0). Results: After down-regulating Src, the cell proliferation was inhibited and cell apoptosis was induced. The proportions of G0/G1 stage of Hela and C33A cell in cell cycle increased while G2/M and S stages decreased. Meanwhile, the mRNA levels of ERK 1, ERK 2, c-Fos and c-Jun increased. And the expression levels of ERK 1/2, phosphorylated ERK 1/2 (p-ERK 1/2) and phosphorylated c-Fos (p-c-Fos) protein decreased, while c-Jun and phosphorylated c-Jun (p-c-Jun) protein expression increased. In addtion, the change level of Hela cell, p-ERK 1/2 and c-Fos protein were lower than that of C33A cell before and after the Src inhibition. Conclusions: Src, involved in regulating the expression of key factors of the ERK signal transduction pathway including p-ERK 1/2 and p-c-Fos, might be capable of promoting the proliferation of cervical cancer cells and inhibiting their apoptosis. The infection with HPV might have adjustable effect on this process.

Abstract
Background Two ongoing prospective randomized trials are evaluating whether omitting axillary lymph node dissection (alnd) in patients with breast cancer (bca) and sentinel lymph node (sln) macrometastases undergoing mastectomy is safe. Determining predictive risk factors for non-sln metastases and developing a model to predict the probability of those patients having non-sln metastases is also important. Methods This retrospective study enrolled 396 patients with bca and 1-2 slns with macrometastases who underwent alnd and mastectomy between January 2012 and December 2016. Factors influencing the non-sln metastases were determined, and a predictive nomogram was formulated. Performance of the nomogram was evaluated by its area under the curve (auc). Results We developed a predictive nomogram with an auc of 0.81 (cross-validation 95% confidence interval: 0.75 to 0.86) that included 4 factors (tumour size, histologic grade, and number of negative slns and axillary lymph nodes on imaging). Conclusions Our predictive nomogram assesses the risk of non-sln metastases in patients with bca and 1-2 sln macrometastases undergoing mastectomy.

Abstract
Objective: To explore the effect of vaginal micro-environment alterations and HPV16 infection and their interaction in the progression of cervical intraepithelial neoplasia. Methods: The participants of this study came from the cervical lesions study cohort in Shanxi province, including 623 women with normal cervical (NC), 303 patients with pathogenically diagnosed low-grade cervical intraepithelial neoplasia (CINⅠ) and 93 patients with pathogenically diagnosed high-grade cervical intraepithelial neoplasia (CINⅡ/Ⅲ). The data of the demographic characteristics of the study subjects and factors related to cervical intraepithelial neoplasia were collected, and HPV16 infection were detected by using flow-through hybridization technology and H(2)O(2), β-glucuronidase, clotting enzyme, neuraminidase and leucocyte esterase in vaginal secretions were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. pH value and vaginal cleanliness were also detected at the same time. The database was established and analyzed by SPSS statistical software (version 22.0). Results: The HPV16 infection rate (trend χ(2)=55.45, P<0.001) and the abnormal rates of H(2)O(2) (trend χ(2)=26.19, P<0.001), pH (trend χ(2)=5.06, P=0.024), vaginal cleanliness (trend χ(2)=19.55, P<0.001), β-glucuronidase (trend χ(2)=17.52, P<0.001) and neuraminidase (trend χ(2)=14.90, P<0.001) increased gradually along with the severity of cervical intraepithelial neoplasia, but the abnormal rates of clotting enzyme and leucocyte esterase showed no same trend. The results of GMDR model analysis showed that there was interaction between HPV16 infection and abnormalities of H(2)O(2), β-glucuronidase, clotting enzyme and neuraminidase in CINⅠ group, and the interaction between HPV16 infection and the abnormalities of vaginal cleanliness, H(2)O(2), β-glucuronidase and neuraminidase in CIN Ⅱ/Ⅲ group. Conclusion: Our findings indicated that the vaginal micro-environment alterations and HPV16 infection could increase the risk of cervical intraepithelial neoplasia, and they might have an important synergistic effect in the progression of cervical intraepithelial neoplasia.

Abstract
BACKGROUND Tumor IL17-producing (IL17A+) cells infiltration has different prognostic values among various cancers. The objective of this study was to assess the effect of IL17A+ cells in gastric cancer. PATIENTS AND METHODS The study included two patient cohorts, the Cancer Genome Atlas cohort (TCGA, n = 351) and the Zhongshan Hospital cohort (ZSHC, n = 458). The TCGA and ZSHC were used for mRNA-related and cells infiltration-related analyses, respectively. The roles of IL17A mRNA and IL17A+ cells in overall survival (OS), response to adjuvant chemotherapy (ACT), and immune contexture were evaluated. Another independent cohort was included to identify the correlation between mRNA of IL17A and IL17A+ cells infiltration (the preliminary Zhongshan Hospital cohort, PZSHC, n = 21). RESULTS The infiltration of IL17A+ cells was positively correlated with the expression of IL17A mRNA (Spearman's ρ = 0.811; P < 0.001). High IL17A mRNA expression and intratumoral IL17A+ cells were correlated with improved OS and remained to be significant after adjusted for confounders. Patients with TNM II/III disease whose tumor present higher intratumoral IL17A+ cells or lower peritumoral IL17A+ cells can benefit more from ACT. Elevated IL17A mRNA expression and increased intratumoral IL17A+ cells infiltration was associated with more antitumor mast cells and nature killer cells infiltration and less pro-tumor M2 macrophages infiltration. High IL17A mRNA expression represented a Th17 cells signature and immune response process and was correlated with increased cytotoxic GZMA, GZMB, IFNG, PRF1, and TNFSF11 expression. CONCLUSIONS IL17A mRNA expression and intratumoral IL17A+ cells infiltration were correlated with antitumor immune contexture. IL17A+ cells infiltration could be used as an independent prognostic biomarker for OS and predictive biomarker for superior response to ACT, and further prospective validation needs to be conducted.

Abstract
Objective: To investigate the effect of heterogeneous nuclear ribonucleoprotein K (hnRNP K) and its interaction with human papillomavirus 16 (HPV16) on cervical intraepithelial neoplasia (CIN). Methods: The participants included 67 women with normal cervix (NC), 69 women with CINⅠ and 68 women with CINⅡ/Ⅲ in a community cohort of pathologically diagnosed women established in Jiexiu of Shanxi province, from June 2014 to June 2015. A structured questionnaire was used to collect the demographic data of the subjects and the related factors of cervical lesions. Cervical exfoliated cells and cervical tissues from biopsy or surgery were selected. The infection status of HPV16 was detected by flow-through hybridization. The protein expression levels of hnRNP K were evaluated by Western blot. SPSS 23.0 software was used to collate and analyze the data. To study the differences in demographic characteristics, related factors, hnRNP K protein and HPV16 infection among NC, CINⅠand CINⅡ/Ⅲgroups, χ(2) test, trend χ(2) test, and Kruskal-Wallis H test were conducted. Multiple comparisons of hnRNP K protein in three groups were completed by using the Bonferroni method. The OR and its 95%CI of hnRNP K, HPV16 and CIN were calculated by using the unconditional logistic regression models. Two-way interactions between hnRNP K protein and HPV16 infection on CIN were analyzed by using additive model and related indicators. Results: HPV16 infection rates were 10.4% in women with normal cervix, 14.5% in women with CINⅠ and 41.2% in women with CINⅡ/Ⅲ, respectively. The differences among three groups were significant (P<0.001). Moreover, the infection rates of HPV16 gradually increased with the increasing severity of CIN (trend χ(2)=18.512, P<0.001). The differences in protein expression of hnRNP K among three groups were significant (H=48.138, P<0.001) and the expressionincreased with the development of cervical lesionss (trend χ(2)=21.765, P<0.001). Results from the interaction analysis indicated that there were additive effects between high expression of hnRNP K protein and HPV16 in CINⅡ/Ⅲ group compared with normal group (API=0.639, 95%CI: 0.083-1.196). In contrast, no such additive effect was found in CINⅠ group. Conclusions: HPV16 infection and over-expression of hnRNP K protein were associated with the increased risk of cervical intraepithelial neoplasia. There might be interaction between hnRNP K protein overexpression and HPV16 infection existed on the progress of CINⅡ/Ⅲ.

Abstract
Objective:We sought to compare clinical characteristics between eosinophilic and non-eosinophilic chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma, and explored the association of chronic rhinosinusitis inflammation subtypewith bronchial inflammation phenotype in CRSwNP with asthma. Method:Fifty-one consecutive patients suffering from CRSwNP with asthma undergoing endoscopic sinus surgery (ESS) were recruited. Preoperative computed tomography (CT), skin-prick test, bronchial provocation test, lung function, and oral fractional exhaled nitric oxide (FeNO) measurements were conducted. Venous blood was taken within 1 week before ESS. Nasal polyps (NPs) specimens were obtained from each patient during ESS, and stained with hematoxylin and eosin. According to the pathologic characteristics of NP samples, fifty-one patients suffering from CRSwNP with asthma were grouped as eosinophilic CRSwNP (ECRSwNP) and non-ECRSwNP and three levels of eosinophil infiltration were recognized. Result:Fifty-one patients suffering from CRSwNP with asthma were grouped as ECRSwNP (n=33) and non-ECRSwNP (n=18). History of surgery, history of allergy, Lund-Mackay scores, duration of asthma, frequency of severity asthma, numbers of asthma exacerbation in the last year, FeNO, blood eosinophil percentage and absolute count were all significantly higher in the ECRSwNP with asthma group compared with the non-ECRSwNP with asthma group (P<0.05). Blood eosinophil percentage had a significant correlation with degree of eosinophil infiltration in NPs (r=0.459, P<0.01) and FeNO (r=0.591, P<0.01). There was a correlation between degree of eosinophil infiltration in NPs and FeNO (r=0.556, P<0.01). Furthermore, Lund-Mackay scores had a positive correlation with blood eosinophil percentage (r=0.327, P<0.05) and degree of eosinophil infiltration in NPs (r=0.412, P<0.01) and FeNO (r=0.691, P<0.01). Conclusion:There is different clinical characteristics between ECRSwNP with asthma and non-ECRSwNP with asthma. These data suggest that CRSwNP inflammation subtype is significantly correlated with bronchial inflammation phenotype in patients suffering from CRSwNP with asthma.

Abstract
Objective: To explore the relationship between abnormal expression of fragile histidine triad (FHIT) gene and methyl-CpG-binding protein 2 (MeCP2) as well as their interaction on cervical cancerization. Methods: A total of 73 patients with cervical squamous cell carcinoma (SCC), 113 patients with cervical intraepithelial neoplasia (CIN Ⅰ, n=45; CINⅡ/Ⅲ, n=68) and 60 women with normal cervix (NC) were included in the study. Real time PCR and Western blot were performed to detect the expression levels of mRNA and protein about FHIT and MeCP2, respectively. The methylation status of FHIT gene CpG island was tested by methylation-specifc PCR (MSP). Kruskal-Wallis H test, χ(2) test, trend χ(2) test and Spearman correlation analysis were conducted with software SPSS 20.0. The interaction was evaluated by generalized multifactor dimensionality reduction (GMDR) model. Results: With the deterioration of cervical lesion, the methylation rates of FHIT gene CpG island (χ(2)=18.64, P<0.001; trend χ(2)=18.08, P<0.001) increased gradually, while the expression levels of FHIT mRNA (H=27.32, P<0.001; trend χ(2)=12.65, P<0.001) and protein (H=47.10, P<0.001; trend χ(2)=29.79, P<0.001) decreased gradually. There was a negative correlation between the methylation rates of FHIT gene CpG island and the expression level of FHIT protein (r=-0.226, P<0.001). The levels of MeCP2 mRNA (H=26.19, P<0.001; trend χ(2)=11.81, P=0.001) and protein (H=69.02, P<0.001; trend χ(2)=47.44, P<0.001) increased gradually with the aggravation of cervical lesions. There was a positive correlation between the expression level of MeCP2 protein and the FHIT mRNA Ct ratio (r=0.254, P<0.001). Expression of proteins were negatively correlated between MeCP2 and FHIT (r=-0.213, P=0.001). The results analyzed by GMDR model showed that there were interactions among high MeCP2 protein expression, the CpG island methylation of FHIT and mRNA and protein expression in CINⅡ/Ⅲ group, and among high MeCP2 mRNA and protein expression, the CpG island methylation of FHIT and low mRNA and protein expression in SCC group. Conclusion: High expression of MeCP2 mRNA and protein, the CpG island methylation and low mRNA and protein expression of FHIT could increase the risk of cervical carcinogenesis, and there might be a synergistic effect on cervical carcinogenesis.

Abstract
Objective: To evaluate the effects of polycyclic aromatic hydrocarbons (PAHs) and high risk human papillomavirus (HR-HPV) infection and their interaction on the progression of cervical intraepithelial neoplasia. Methods: A total of 486 patients, including 208 women with normal cervix (NC), 154 patients with low-grade cervical intraepithelial neoplasm (CINⅠ), 124 patients with high-grade cervical intraepithelial neoplasm (CINⅡ/Ⅲ), were selected from the cervical lesions cohort from June to December, 2014. HR-HPV was detected by using flow-through hybridization technology and the urine concentration of 1-hydroxypyrene (1-OHP) was detected with high performance liquid chromatography. By using software SPSS 22.0, the χ(2) test, trend χ(2) test, Kruskal-Wallis H test, Nemenyi rank test and Spearman rank correlation analysis were performed. And the interaction effects were evaluated by additive model. Results: The HR-HPV infection rates in NC, CINⅠ and CINⅡ/Ⅲ groups were 27.9%, 37.0% and 58.9%, respectively. The urine concentrations of 1-OHP (μmol/molCr) were 0.07±0.09, 0.11±0.10 and 0.17±0.15, respectively. With increasing severity of the cervical lesions, the HR-HPV infection rate gradually increased (trend χ(2)=29.89, P<0.001) and the high exposure rate of PAHs gradually increased (trend χ(2)=27.94, P<0.001). HR-HPV infection was positively correlated with 1-OHP exposure (r=0.680, P<0.001). There was a positive additive interaction between HPV infection and PAHs exposure in CIN Ⅱ/Ⅲ group, but it was not found in CIN Ⅰ group. Conclusion: Both HR-HPV infection and high exposure of PAHs might increase the risk of cervical intraepithelial neoplasm, and might have a synergistic effect on the progression of high-grade cervical intraepithelial neoplasia.

Abstract
Objective: To explore the effect of polycyclic aromatic hydrocarbons (PAHs) and p16, FHIT gene CpG island methylation, as well as their interaction in cervical intraepithelial neoplasias. Methods: Objects of this study were from a cohort of cervical lesions study in Yangqu county of Shanxi province. All the patients were diagnosed pathologically, that including 83 patients with high-grade cervical intraepithelial neoplasia (CINⅡ/Ⅲ), 86 patients with low-grade cervical intraepithelial neoplasia (CINⅠ) and another 91 women under normal cervical (NC) condition. 1-hydroxy pyrene in the urine was detected by high performance liquid chromatography (HPLC) while CpG island methylation status of tumor suppressor gene p16 and FHIT were measured by methylation-specifc polymerase chain reaction (MSP). Data were analyzed with Kruskal-Wallis H test, chi-square test and trend of chi-square test. Logistic regression models were used to estimate the odds ratio (OR) and corresponding 95% confidence intervals (95%CI) between influencing factors and the cervical disease by using the SPSS statistical software (version 20.0). The interaction under study was evaluated by using the generalized multifactor dimensionality reduction (GMDR) model. Results: Level of 1-hydroxy pyrene (H=50.743, P<0.001) and the high exposure rate of 1-hydroxy pyrene (trend χ(2)=20.146, P<0.001) were gradually increasing along with the severity of cervical intraepithelial neoplasia. The CpG island methylation rates of p16, FHIT in CINⅠand CINⅡ/Ⅲ group were higher than that in NC group, and gradually increasing along with the severity of cervical intraepithelial neoplasia (trend χ(2)=9.75, P=0.002; trend χ(2)=10.39, P=0.001). Results from the GMDR model showed that interaction existed among the high exposure of 1-hydroxy pyrene and the CpG island methylation of p16, FHIT in CINⅠ and CINⅡ/Ⅲ group. Conclusion: Under the high exposure of 1-hydroxy pyrene and the CpG island methylation of p16, FHIT appeared to have increased the risk of cervical intraepithelial neoplasia and causing synergistic effect in cervical intraepithelial neoplasia.
