Abstract
Coiled-Coil Domain-Containing (CCDC) is a large class of structural proteins containing left-handed supercoiled structure. The clinical value and the functional implication of CCDC in colorectal cancer (CRC) remain unknown. Based on the genetic, transcriptional, and clinical data from The Cancer Genome Atlas, five of thirty-six CCDC proteins were differentially expressed in the CRC and associated with the survival of patients with CRC. A CCDC-score model was established to evaluate the prognosis of patients. The potential function of Coiled-Coil Domain-Containing 154 (CCDC154) was investigated using bioinformatical methods, which unveiled that high expression of CCDC154 indicates poor survival for patients with CRC and correlates with low infiltration of CD8+ T cells and high infiltration of neutrophils, indicating that CCDC154 enhances tumor growth and metastasis. CCDC154 interacts with Minichromosome Maintenance Complex Component 2 (MCM2) protein and promotes malignant phenotype via MCM2. We validated the expression level and survival prediction value of CCDC154 in clinical samples, and analyzed its co-expression of MCM2, Ki-67 and p53. This work discloses the role of CCDC in clinical setting and CCDC154 functions in CRC.

Abstract
Background Trastuzumab (TRA) shows significant efficacy in patients with human epidermal growth factor receptor 2 (HER2)-positive gastric cancer (GC). While TRA can help treat HER2-positive breast cancer, TRA resistance is a key clinical challenge. Nestin reportedly regulates the cellular redox homeostasis in lung cancer. This study aimed at identifying the functions of Nestin on the TRA sensitivity of HER2-positive GC cells. Methods Real-time polymerase chain reaction (PCR) and Western blotting (WB) were performed to explore the association between the mRNA and protein expression profiles, respectively, of Nestin and the Keap1-Nrf2 pathway. The influence of Nestin overexpression on the in vitro sensitivity of GC cells to TRA was explored by Cell Counting Kit-8 (CCK-8) assay, colony formation assay, reactive oxygen species (ROS) detection, and flow cytometry. Results TRA treatment caused Nestin downregulation in two HER2-positive GC cell lines (MKN45 and NCI-N87). Nestin overexpression reduced the sensitivity of GC cells to TRA. The expression and activity of Nrf2 and relevant downstream antioxidant genes were increased by Nestin overexpression. Nestin overexpression also significantly suppressed TRA-induced apoptosis and ROS generation. In vivo tumor growth experiment with female BALB/c nude mice indicated that Nestin upregulation restored the tumor growth rate which was inhibited by TRA treatment. Conclusions Collectively, the inhibitory effect of Nestin on the TRA sensitivity of cells to TRA was confirmed in this study. These results imply that the antioxidant Nestin-Nrf2 axis may play a role in the mechanism underlying the resistance of GC cells to TRA.

Abstract
Background Metabolic reprogramming is a feature of cancer. However, colon cancer subtypes based on the glycolysis‒cholesterol synthesis axis have not been identified, and little is known about connections between metabolic features and the tumor microenvironment. Methods Data for 430 colon cancer cases were extracted from The Cancer Genome Atlas, including transcriptome data, clinical information, and survival outcomes. Glycolysis and cholesterol synthesis-related gene sets were obtained from the Molecular Signatures Database for a gene set variation analysis. The relationship between the genomic landscape and immune landscape were investigated among four metabolic subtypes. Hub genes were determined. The clinical significance of candidate hub gene was evaluated in 264 clinical samples and potential functions were validated in vitro and in vivo. Results Colon cancer cases were clustered into four metabolic subtypes: quiescent, glycolytic, cholesterogenic, and mixed. The metabolic subtypes differed with respect to the immune score, stromal score, and estimate score using the ESTIMATE algorithm, cancer-immunity cycle, immunomodulator signatures, and signatures of immunotherapy responses. Patients in the cholesterogenic group had better survival outcomes than those for other subtypes, especially glycolytic. The glycolytic subtype was related to unfavorable clinical characteristics, including high mutation rates in TTN, APC, and TP53, high mutation burden, vascular invasion, right colon cancer, and low-frequency microsatellite instability. GGH, CACNG4, MME, SLC30A2, CKMT2, SYN3, and SLC22A31 were identified as differentially expressed both in glycolytic-cholesterogenic subgroups as well as between colon cancers and healthy samples, and were involved in glycolysis‒cholesterol synthesis. GGH was upregulated in colon cancer; its high expression was correlated with CD4+ T cell infiltration and longer overall survival and it was identified as a favorable independent prognostic factor. The overexpression of GGH in colon cancer-derived cell lines (SW48 and SW480) inhibited PKM, GLUT1, and LDHA expression and decreased the extracellular lactate content and intracellular ATP level. The opposite effects were obtained by GGH silencing. The phenotype associated with GGH was also validated in a xenograft nude mouse model. Conclusions Our results provide insight into the connection between metabolism and the tumor microenvironment in colon cancer and provides preliminary evidence for the role of GGH, providing a basis for subsequent studies.

Abstract
Objective: To investigate the feasibility, safety and efficacy of transoral robotic surgery (TORS) in the treatment of lingual thyroglossal duct cyst (LTGDC). Methods: The clinical data of 10 patients with LTGDC treated with TORS in Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from May 2017 to November 2020 were analyzed retrospectively,including 6 males and 4 females, aged 5-44 years. The cysts were fully exposed, and resection usually started from the cephalic side of lesions. The range of resection was 3 to 5 mm away from the lesions, and partial hyoid bone was removed if necessary. Intra-operative robotic set-up time,operation time and estimated blood loss,and post-operative local bleeding, dyspnea and recovery time for oral intake were analyzed. SPSS 12.0 software was used for statistical analysis. Results: The cysts in all 10 patients were successfully resected by TORS with da Vinci Si surgical system. The mean robotic set-up and exposure time, operation time, estimated intraoperative blood loss and recovery time for oral intake were (15.5±7.1) min, (17.6±7.4) min, (8.9±6.4)ml and (2.3±2.2)days, respectively. No patient required tracheostomy intra-or post-operatively, and no symptoms of airway obstruction, postoperative bleeding, pharyngeal fistula, hoarseness and neurological impairment occurred after operation. The patients were followed up for 5 to 47 months, with median follow-up time of 17 months, and no recurrence was observed. Conclusion: TORS is safe and feasible for resection of LTGDC, with rapid recovery and low recurrence rate.

Abstract
Clustered regularly interspaced short palindromic repeats (CRISPR) system provides adaptive immunity against plasmids and phages in prokaryotes. This system inspires the development of a powerful genome engineering tool, the CRISPR/CRISPR-associated nuclease 9 (CRISPR/Cas9) genome editing system. Due to its high efficiency and precision, the CRISPR/Cas9 technique has been employed to explore the functions of cancer-related genes, establish tumor-bearing animal models and probe drug targets, vastly increasing our understanding of cancer genomics. Here, we review current status of CRISPR/Cas9 gene editing technology in oncological research. We first explain the basic principles of CRISPR/Cas9 gene editing and introduce several new CRISPR-based gene editing modes. We next detail the rapid progress of CRISPR screening in revealing tumorigenesis, metastasis, and drug resistance mechanisms. In addition, we introduce CRISPR/Cas9 system delivery vectors and finally demonstrate the potential of CRISPR/Cas9 engineering to enhance the effect of adoptive T cell therapy (ACT) and reduce adverse reactions.

Abstract
BACKGROUND The clinical role of deficient DNA mismatch repair (dMMR)/microsatellite instability-high (MSI-H) in gastric cancer (GC) is still controversial. We aimed to analyze the relationship between dMMR/MSI-H and clinicopathological features along with survival. METHODS Patients who were diagnosed with GC at the three big cancer centers in China from 2015 to 2020 were evaluated retrospectively. MMR/MSI status was assessed using immunohistochemistry/PCR. Clinical and pathological data were collected from the medical record system. RESULTS A total of 196 patients with dMMR/MSI-H status were enrolled for analysis. The prevalence of MSI-H/dMMR in GC was 6.6%. Another 694 proficient MMR (pMMR) GC patients were enrolled for comparison. Compared with pMMR patients, dMMR/MSI-H patients were associated with older age, female predominance, distal location in the stomach, earlier TNM stage, intestinal subtype, better differentiation, and more negative HER2 status. The median overall survival (OS) of the dMMR/MSI-H group was better than that of the pMMR/microsatellite stability (MSS) group (not reached vs. 53.9 months, p = 0.014). Adjuvant chemotherapy had no impact in both disease-free survival (DFS) and OS of dMMR/MSI-H patients (p = 0.135 and 0.818, respectively). dMMR/MSI-H patients had poorer response and progression-free survival (PFS) of first-line chemotherapy, though they were statistically significant (p = 0.361 and 0.124, respectively). CONCLUSIONS dMMR/MSI-H GC patients have specific clinicopathological characteristics and better prognosis than pMMR patients.

Abstract
The use of immune checkpoint inhibitors (ICIs) is rising exponentially in numerous cancers, but immune-related adverse events can occur. We report a rare case of high-grade drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome developed stepwise in a patient with gastric cancer after nivolumab treatment. Subclinical myocarditis was sensitively detected by cardiovascular magnetic resonance 3 weeks after initiating nivolumab. Eruption, eosinophilia, and interstitial pneumonitis occurred 1 week later. Corticosteroids were started and his condition improved. Four months later, when he was still on steroids tapering off, acute kidney injury and sequential herpes zoster virus activation developed. Severe acute tubulointerstitial nephritis (ATN) with an intense infiltration of lymphocytes was observed on renal biopsy. In blood, a substantial shift to Th2 response, an increase of Th17 cells, and strikingly enriched granzyme B+ and perforin+ CD8+ T cells were detected at ATN onset. Serum interleukin (IL)-5, IL-17, interferon gamma, and IL-6 levels were consistently elevated. Further molecular profiling identified a DRESS risk allele human leukocyte antigen (HLA)-A*31:01 in this patient. His ATN responded favorably to a high dose of corticosteroids. In parallel, complete antitumor response was observed during the clinical course of DRESS. This is the first ever case report of nivolumab-associated DRESS syndrome with exploration of the mechanisms from the histopathological, cellular and molecular aspects. Nivolumab-induced DRESS may result from type IV hypersensitivity-related 'off-target effect' and PD-1 block-mediated 'on-target effect'. HLA risk alleles may constitute the genetic susceptible basis. HLA typing assay has the potential to screen susceptible individuals to avoid ICI-induced DRESS.

Abstract
Objective: To investigate the effect of neoadjuvant chemotherapy (NCT) on the lymph node ratio (LNR) of patients with stage ⅢA-N2 non-small cell lung cancer (NSCLC), and analyze the relationship between LNR and prognosis. Methods: The data of 128 patients with stage ⅢA-N2 NSCLC admitted to the Department of Cardiothoracic Surgery of the First Affiliated Hospital of Hebei North University from January 2013 to December 2018 were retrospectively collected. The patients were divided into two groups according to the treatment method. The patients in the observation group (64 cases) were treated with NCT and surgery, and the patients in the control group (64 cases) were treated with surgery. Lymph node metastasis and survival were observed in the two groups. Subgroups were divided according to LNR and N2 lymph node status, and survival analysis was performed for each subgroup. Univariate and multivariate analysis were conducted for the observation group. Results: The number of metastatic lymph nodes, the proportion of patients with positive lymph nodes, and the rate of lymph node metastasis in the observation group were lower than those in the control group,3.8±2.1 vs 4.9±2.4,92.2% vs 100%,19.1% vs 22.4% respectively (all P<0.05). Progression-free survival (PFS) and overall survival (OS) in the observation group were better than those in the control group (both P<0.05). Both the observation and control subgroups with low LNR had better PFS and OS than the subgroups with high LNR (both P<0.05). Patients in the observation group with non-multi-site N2 lymph node metastasis had better PFS and OS (both P<0.05). Univariate analysis of observation group showed that patients with low LNR had better 2-year PFS and OS(both P<0.05). Multivariate analysis showed that the higher the LNR, the greater the risk of death (HR=2.178,95%CI: 1.025-4.626,P=0.043) and progression (HR=2.130,95%CI: 1.123-4.038,P=0.021). Conclusion: NTC could improve the prognosis and reduce LNR of patients with stage ⅢA-N2 NSCLC, and LNR was expected to be a prognostic indicator.

Abstract
Objective: To investigate the status of monotherapy for newly diagnosed tic disorders and its comorbidity in children, so as to provide a reference for clinical medication. Methods: A questionnaire survey was conducted to collect the application experience of monotherapy for newly diagnosed tic disorders and comorbidities in 110 pediatric neurologists and psychiatrists from Chinese Tic Disorders Study Consortium from February to August in 2019. Doctors were asked to rate treatment options based on a rank 5-point scale with "1" least appropriate and "5" most appropriate. The drug evaluation index was based on the comparison of the median score of a single drug with the overall scores of all drugs in this disease (M (Q1, Q3)), single drug M ≥ overall Q3 was recommended as preferred drugs; overall Q1≤ single drug M < overall Q3 was considered as secondary drugs; single drug M < overall Q1 was considered as unsuitable drugs. Results: Among 110 electronic questionnaires, 94 (86%) were availably responded, responding doctors included 37 (39%) males and 57 (61%) females, the age of responding doctors was (48±10) years, and their working year was (17±10) years. In the investigation of the first and second monotherapy for newly diagnosed tic disorders in children without comorbidities, there were no preferred drugs for mild transient tic disorders. The scores of clonidine, aripiprazole and tiapride were 4 (3, 4), 4 (3, 4), 4 (4, 5) scores respectively, and were greater than overall scores (3 (2, 4) scores), so they could be recommended as the preferred drugs for moderate chronic tic disorders, the recommendation for initial mild Tourette syndrome (TS) treatment was the same as preferred drugs for moderate chronic tic disorders. Similarly, clonidine, aripiprazole, tiapride and haloperidol could be recommended as the preferred drugs for other kinds of tic disorders. As for the second monotherapy, the preferred drugs for moderate transient tic disorders, mild chronic tic disorders and severe TS were all aripiprazole, tiapride, haloperidol, sulpiride, clonidine and topiramate. While clonidine, aripiprazole, tiapride could be considered as preferred drugs for severe transient tic disorders, moderate to severe chronic tic disorders and mild to moderate tic disorders. In the investigation of monotherapy for newly diagnosed tic disorders in children with comorbidities, for moderate chronic tic disorders and TS comorbid with obsessive-compulsive disorder, aripiprazole (4 (3, 5) scores) and sertraline (4 (3, 4) scores) were preferred drugs,the median scores of which were all greater than overall scores (3 (3, 4) scores), they were also the preferred treatment for severe transient tic disorders and mild chronic tic disorders. For mild and moderate transient tic disorders, severe chronic tic disorders and TS comorbid with obsessive-compulsive disorder, aripiprazole, fluvoxamine, fluoxetine, haloperidol and sertraline were preferred drugs. When comorbid with attention deficit hyperactivity disorder (ADHD), severe transient tic disorders, moderate chronic tic disorders and TS, tomoxetine and clonidine were recommended as preferred drugs (both 4 (4, 5) scores), and tomoxetine and clonidine were also the preferred treatment for severe TS. For severe chronic tic disorders comorbid with ADHD, clonidine (5(4, 5) scores) was preferred drug, greater than overall scores (4 (3, 5) scores), while for mild and moderate transient tic disorders clonidine, tomoxetine, guanidine and methylphenidate were recommended as preferred drugs. For mild chronic tic disorders and TS comorbid with ADHD tomoxetine was preferred drug. When comorbid with sleep disorders, there were no preferred drugs for mild transient tic disorders; estazolam (3 (2, 3) scores) was the preferred drug for mild chronic tic disorders and TS comorbid with sleep disorders. For othe kind of tic disorders comorbid with sleep disorders, estazolam, melatonin and clonazepam were preferred drugs. When comorbid with anxiety and depressive disorders, for all kinds of tic disorders sertraline was recommended as preferred drugs, the median scores of sertraline were all (4 (3, 5) scores) in severe transient tic disorders, moderate to severe chronic tic disorders and moderate TS, and greater than overall scores (3 (3, 4) scores). While severe chronic tic disorders comorbid with anxiety and depressive disorders, fluvoxamine could also be chosen as preferred drugs. Conclusions: Drug therapy is not recommended for mild transient tic disorders, while tiapride, aripiprazole, clonidine, and haloperidol are mainly preferred drugs for the other kinds of tic disorders. Corresponding drugs should be selected when tic disorders are combined with obsessive-compulsive disorder, ADHD, sleep disorders, anxiety, depression, etc.

Abstract
OBJECTIVE United Nations Programme on human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome and World Health Organization believe that some of the benchmark numbers collected may be inaccurate when using the multiplier method to estimate the size of populations most at risk of acquiring HIV. Here, study data have been evaluated to characterize the inaccurate benchmark numbers. STUDY DESIGN The study design used is a systematic review. METHODS Studies published from 1 January 2004 to 1 December 2019 using the multiplier method to estimate the population proportions of men who have sex with men (MSM) and female sex workers (FSWs) in China were reviewed. Five electronic bibliographic databases were searched: Medline, the China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, Wanfang Data, and the Chinese BioMedical Literature Database. RESULTS In all eight studies of FSW, six of the estimated population proportions fell within the range of national estimates. However, the estimated MSM population proportions of all 18 studies fell outside the range of national estimates. CONCLUSIONS When estimating the MSM population, the use of benchmark numbers from homosexual websites or MSM-frequented sites usually led to an inaccurate estimation. Therefore, benchmark numbers from services/programs that meet fundamental needs, such as those dealing with health and wellness, should be used.

Abstract
Objective: To investigate the correlation between single nucleotide polymorphisms (SNPs) of SIRT1 gene promoter sequence and senile degenerative heart valvular disease (SDHVD). Methods: A total of 236 SDHVD patients and 285 healthy controls who visited the Affiliated Hospital of Jining Medical University between February 2012 and October 2016 were enrolled. SNPs of SIRT1 gene promoter were detected by Sanger sequencing. Typing and correlation were analyzed by χ(2) test and Logistic regression analysis. Haplotype and linkage disequilibrium were analyzed by Haploview4.2 software and SHEsis online software. The effect of SNPs on the binding of transcription factors to SIRT1 gene promoter was analyzed by electrophoretic mobility shift assay(EMSA). The transcription factors affected by SNPs were predicted by Transfac online software. Results: The frequency distribution of GG genotype of rs3740051 in the SDHVD group was significantly higher than that in the control group (χ(2)=4.855, P=0.028). There was a correlation between GG genotype of the rs3740051 and SDHVD. After adjusting for age, the risk of SDHVD in the carrier of GG genotype was 3.079 times higher than that of AA genotype(OR=3.079, 95%CI: 1.156-8.201, P=0.024). The five SNPs (rs3740051, rs932658, rs35995735, rs3740053 and rs2394443) showed strong linkage disequilibrium(D'>0.8). The haplotype analysis of the five SNPs (haplotype frequency<0 was ignored in the analysis) showed that 11 haplotypes (P<0.05) were formed, and the frequency of *A**C, AA**C, *AG*C, AAG*C, AA*AC, *AGAC and AAGAC in SDHVD group were significantly higher than that in control group (P<0.05, OR>1, 95%CI does not contains 1). EMSA showed that the color of the binding bands incubated by wild type probe and nucleoprotein was darker than that incubated by DNA sequence variation probe and nucleoprotein. Conclusion: The GG genotype of rs3740051 is associated with SDHVD and may be a risk genotype for SDHVD. The haplotype AC (across rs932658 and rs2394443) may be a dangerous haplotype of SDHVD. rs3740051 may affect the occurrence and development of SDHVD by interfering with the binding of FOXC protein to SIRT1 gene promoter.

Abstract
Objective: To evaluate the indication, safety and effectiveness of transoral robotic surgery (TORS) for oropharyngeal cancer based on our preliminary experience. Methods: Twelve patients, including six with tonsil cancer, five with tongue base cancer and one with posterior pharyngeal wall cancer, who underwent TORS with Da Vinci Si surgical system from March 2017 to October 2018 at Tongji Hospital of Huazhong University of Science Technology were respectively analyzed. And the surgical time, intraoperative blood loss, postoperative local bleeding, dyspnea, nerve function injury, oral intake time, whether or not to receive chemoradiotherapy were analyzed. Results: All tumors in the 12 patients were en bloc removed by TORS. Surgical time ranged from 25 to 80 min with an average of 34.2 min. The blood loss ranged from 10 ml to 50 ml with an average of 20.8 ml. The recovery time for oral intake ranged from 1 day to 30 days with an average of 8.4 days. No patient underwent tracheostomy after TORS. Also, no patient manifested with airway obstruction, bleeding or nerve injury symptoms after operation. All 12 patients reached pathologically negative surgical margins. The patients were followed up for 4 to 22 months, with a median of 12 months. All patients who combined with more advanced than T3 stage, or more advanced than N2 stage were recommended to oncologist, then, followed with radiotherapy or chemoradiotherapy if no relevant contradictions occurred. No local recurrence or distant metastasis case was found. Conclusion: With proper indications, the application of TORS in oropharyngeal cancer is a relatively safe, effective and minimal invasive therapy, which merits more clinical applications.

Abstract
BACKGROUND The aim of this study was to compare the efficacies of the XELOX and DOS regimens as preoperative chemotherapy in patients with locally advanced gastric cancer. METHODS All cases of locally advanced gastric cancer treated with the XELOX or DOS regimen were reviewed retrospectively. Propensity score matching (PSM) was carried out to reduce selection bias based on age, gender, location, Lauren type, carcinoembryonic antigen level, clinical tumor stage, and clinical node stage. RESULTS From January 2010 to December 2016, 248 patients were matched; 159 of them received the XELOX regimen and 89 the DOS regimen. The response rates in the XELOX and DOS groups were 34.5 and 38.1%, respectively (P = 0.823). After four cycles of chemotherapy, 111 patients (69.8%) in the XELOX group and 65 patients (73.0%) in the DOS group underwent radical surgery (P = 0.485). The median progression-free survival (33.0 months vs. 18.7 months, P = 0.0356) and the median overall survival (43.8 months vs. 29.1 months, P = 0.0003) were longer for patients who received the DOS regimen than for those who received the XELOX regimen. The occurrence of grade 3 to 4 toxicity was similar in the two groups. CONCLUSIONS For locally advanced gastric cancer patients, the DOS regimen showed more benefit than the XELOX regimen as preoperative chemotherapy, without any added toxicity effects.

Abstract
Asymmetric synthesis of chiral β-hydroxy esters, the key building blocks for many functional materials, is currently of great interest. In this study, the biocatalytic anti-Prelog reduction of methyl acetoacetate (MAA) to methyl-(R)-3-hydroxybutyrate ((R)-HBME) was successfully carried out with high enantioselectivity using the whole cell of engineered E. coli, which harbored an AcCR (carbonyl reductase) gene from Acetobacter sp. CCTCC M209061 and a GDH (glucose dehydrogenase) gene from Bacillus subtilis 168 for the in situ regeneration of the coenzyme. Compared with the corresponding wild strain, the engineered E. coli cells were proved to be more effective for the bio-reduction of MAA, and afforded much higher productivity. Under the optimized conditions, the product e.e. was >99.9% and the maximum yield was 85.3% after a reaction time of 10 h, which were much higher than those reported previously. In addition, the production of (R)-HBME increased significantly by using a fed-batch strategy of tuning pH, with a space-time yield of approximately 265 g L-1 d-1, thus the issue in previous research of relatively low substrate concentrations appears to be solved. Besides, the established bio-catalytic system was proved to be feasible up to a 150 mL scale with a large-scale relatively high substrate concentration and selectivity. For further industrial application, these results open a way to use of whole cells of engineered E. coli for challenging higher substrate concentrations of β-ketone esters enantioselective reduction reactions.

Abstract
Objective: To investigate the effect and mechanism of long non-coding RNA-metastasis associated lung adenocarcinoma transcript 1, (LncRNA-MALAT1) on invasion and metastasis of esophageal cancer cell EC-109. Methods: EC-109 cells were transfected with lentiviral vector carrying short hairpin RNA of MALAT1( shRNA-MALAT1) or a nonspecific shRNA control (shRNA-control). The expressions of MALAT1, microRNA-200a, ZEB1 and ZEB2 were detected by qRT-PCR. The effect of shRNA-MALAT1 on invasion of EC-109 cells was determined by transwell assay. The expressions of components of epithelial-msenchymal transition pathway in EC-109 cells were determined by immunofluorescence array and western blotting. The expression relationship between MALAT1 and miR-200a in EC-109 cells was detected by dual-luciferase reporter assay. Results: The result of qRT-PCR showed that the expressions levels of MALAT1, ZEB1 and ZEB2 in shRNA-MALAT1 group were 0.43±0.06, 0.64±0.04 and 0.51±0.04, respectively, significantly lower than 0.97±0.08, 1.06±0.07 and 0.98±0.05 in shRNA-control group and 1 in control group, respectively(all P<0.05). Transwell assay showed that the number of invaded cells in shRNA MALAT1 group was (96.81±10.43) per low-power field, markedly lower than that of (278.44±13.28) per low-power field in shRNA-control group (P<0.01). Immunofluorescence staining and Western blotting showed that MALAT1 downregulation significantly reduced the expressions of proteins related to EMT signal pathway in EC-109 cells.Dual luciferase reporter assay showed that compared to negative control, the activities of luciferase reporter in EC-109 cells co-transfected with pmirGLO-MALAT1-wt and miR-200a were significantly down-regulated. While co-transfected pmirGLO-MALAT1-mut with miR-200a mimics had no effect on the luciferase reporter activities of MALAT1. Conclusion: LncRNA MALAT1 functions as a competing endogenous RNA to regulate the expressions of ZEB1 and ZEB2 by sponging miR-200a and promotes invasion and migration of esophageal cancer cells through inducing epithelial-mesenchymal transition.

Abstract
Objective: To explore the ultrastructural alteration of extraocular muscle proprioceptor in congenital idiopathic nystagmus (CIN). Methods: Case-control study. Ten extraocular muscle samples were collected from five CIN children who underwent nystagmus surgeries in Beijing Children's Hospital from March 2015 to March 2016. Another ten extraocular muscle specimens were collected from five strabismus children in surgery at the same period as normal contrast. There were 3 male patients and 2 female patients of CIN with age of 61-147 months (median age: 91 months). The ultrastructure of extraocular muscle proprioceptors was compared between these two groups by transmission electron microscope. Results: Twenty-three proprioceptors were found in extraocular muscle specimens of CIN children, whereas thirty-three proprioceptors were detected in strabismus children. The ultrastructure of extraocular muscle proprioceptor of CIN altered greatly comparing with that of the control. Fourteen extraocular muscle proprioceptors of CIN were discovered much smaller and vacuolated not only at inner capsules but also at the space between inner and outer capsules with lipofuscins and myeloid bodies in the intrafusal muscle fibers. Sensory nerve fibers degenerated greatly with a lot of lipofuscins and myeloid bodies in these sensory nerve fibers. Demyelination also appeared in some severe cases. Nine extraocular muscle proprioceptors of CIN showed significant dissolving degeneration of myofibrils and proliferation of collagen fibrils. The normal structures could not be distinguished in these proprioceptors. And these structural disorders also appeared in extrafusal muscle fibers and nerve endings. Conclusion: The ultrastructure of extraocular muscle proprioceptor in CIN turned much smaller and had significantly structural disorder.(Chin J Ophthalmol, 2017, 53: 136-139).

Abstract
Complementary DNA (cDNA) is valuable for investigating protein structure and function in the study of life science, but it is difficult to obtain by traditional reverse transcription. We employed a novel strategy to clone human leukemia inhibitory factor (hLIF) gene cDNA from genomic DNA, which was directly isolated from the mucous membrane of mouth. The hLIF sequence, which is 609 bp long and is composed of three exons, can be acquired within a few hours by amplifying each exon and splicing all of them using overlap-PCR. This new approach developed is simple, time- and cost-effective, without RNA preparation or cDNA synthesis, and is not limited to the specific tissues for a particular gene and the expression level of the gene.

Abstract
This study reported the analysis of KIT ligand (KITLG) gene polymorphisms in 681 goats of three breeds: Xinong Saanen (SN), Guanzhong (GZ), and Boer (BG). In addition, the study identified three allelic variants: g.769T>C and g.817G>T in SN and GZ breeds, and g.9760G>C in the three goat breeds. The g.769T>C and g.817G>T loci were closely linked (r(2) > 0.33). All the single nucleotide polymorphism loci were in Hardy-Weinberg disequilibrium (P < 0.05). Significant associations were found for litter size with all three loci. Therefore, these results suggest that the KITLG gene is a strong candidate gene affecting litter size in goats.

Abstract
The expression of osteopontin (OPN) has been correlated with tumor growth and metastasis. However, the mechanisms by which OPN promotes tumor metastasis remain unclear. In this study, we aimed to investigate the anti-tumor effects of OPN by silencing OPN expression in the gastric cancer cell line SGC7901, using lentiviral-OPN small interfering RNA (siRNA) technology. Plasmid vectors containing OPN siRNAs were generated, encoded with lentiviral vector and transfected into SGC7901 cells (SGC-OPN- cells). OPN mRNA and protein expression were examined using real-time reverse transcription polymerase chain reaction (RT-PCR) and Western blotting techniques. The tumorigenicity and metastatic potential of SGC7901 cells were studied in nude mice. Expression of OPN and vascular endothelial growth factor (VEGF) in lung metastatic tumor specimens were also examined using immunohistochemistry (IHC). Among the three siRNA sequences tested, siRNA2 most remarkably inhibited mRNA levels of OPN; lentiviral-siRNA2 was stably transfected into SGC7901 cells to generate SGC-OPN- cells. SGC-OPN- cells had significantly decreased OPN expression compared to control cells (relative intensities were 0.14 ± 0.06 vs. 0.95 ± 0.16 in controls, P<0.01). A substantial reduction in detectable tumors was found in mice implanted with SGC-OPN- cells compared to controls (4.62 ± 1.24 vs. 8.35 ± 2.27 cm3 in controls, P<0.01). In addition, mice implanted with SGC-OPN- cells survived longer (101.2 ± 22.5 vs. 89.2 ± 24.6 d, P<0.01) and were demonstrated to have less metastases compared to mice implanted with SGC7901 control cells. Interestingly, lentiviral-siRNA2 also suppressed the expression of OPN and VEGF in metastatic lung specimens. Lentiviral-mediated OPN siRNA significantly reduced OPN gene expression, suppressing the growth and metastasis of gastric cancers, which might be related to reduced expression of VEGF. Therefore, OPN could serve as a promising therapeutic target for gastric cancer.

Abstract
BACKGROUND & AIMS The transcription factor Krüppel-like factor 8 (KLF8) has a role in tumor development, growth, and metastasis, but its role in hepatocellular carcinoma (HCC) is not clear. METHODS KLF8 expression in human HCC cell lines and tumor tissues was measured by quantitative real-time polymerase chain reaction, immunoblot, and immunochemical analyses. The effects of KLF8 depletion or overexpression in HCC cells were observed in cultured cells and in mice. Changes in gene expression patterns in HCC cells in which levels of KLF8 were reduced using small interfering RNA were investigated by microarray analysis. The clinical significance of KLF8 expression levels were validated using tissue microarray analysis of surgical samples from 314 HCC patients. RESULTS KLF8 was overexpressed in highly metastatic HCC cell lines and in samples from patients with recurrent HCC. In cultured cells, KLF8 up-regulation promoted cell proliferation and invasion; inhibited apoptosis; down-regulated N-cadherin, vimentin, and fibronectin; and up-regulated E-cadherin. In mice, overexpression of KLF8 increased HCC progression and metastasis. Microarray analysis showed that reduction of KLF8 in HCC cells down-regulated expression of multiple genes involved in tumor progression and metastasis. KLF8 expression was a significant predictor of overall survival (P = .040) and time to HCC recurrence (P = .006) and was associated with early tumor recurrence (P = .001). CONCLUSIONS KLF8 promotes HCC cell proliferation and invasion, inhibits apoptosis, and induces the epithelial-to-mesenchymal transition. KLF8 up-regulation might be used to indicate poor prognosis or early recurrence of cancer in patients who have had surgery for HCC.

Abstract
BACKGROUND Osteopontin (OPN) is a multifunctional 34-kDa extracellular matrix protein that can influence the inflammatory process. However, the presence of OPN in human sinonasal mucosa and its roles in the inflammatory process of chronic rhinosinusitis (CRS) are not clear. This study investigated the expression of OPN in human sinonasal mucosa, its cytokine-driven expression regulation, and its effect on cytokine production in sinonasal mucosa. METHODS Surgical samples were investigated by means of quantitative reverse transcriptase polymerase chain reaction for evaluation of OPN messenger RNA (mRNA) expression, and the presence and location of OPN protein expression were analyzed using immunohistochemistry. Furthermore, nasal explant culture was used to investigate the mutual regulatory interactions between interferon (IFN)-gamma, interleukin (IL)-4, IL-5, IL-13, IL-1beta, and tumor necrosis factor (TNF)-alpha and OPN in sinonasal mucosa. RESULTS Osteopontin expression was significantly upregulated in CRS tissues compared with control tissues. There was a further significant increase of OPN expression in patients with nasal polyps (NPs) and asthma. Immunohistochemistry revealed positive staining of OPN in epithelial cells, submucosal glands, infiltrating cells, and extracellular matrix. Osteopontin mRNA was induced by IFN-gamma, IL-1beta, and TNF-alpha, but inhibited by IL-4 and IL-13. On the contrary, OPN induced IFN-gamma, IL-4, IL-5, IL-13, IL-1beta, and TNF-alpha production in sinonasal mucosa. CONCLUSIONS The expression of OPN is upregulated in CRS. The mutual regulatory interactions between OPN and inflammatory cytokines suggest that OPN may play an important role in the pathogenesis of CRS.

Abstract
BACKGROUND Clara cell 10-kDa protein (CC10) is a multifunction protein with anti-inflammatory and immunomodulatory effects; hence we compared the CC10 expression between chronic rhinosinusitis (CRS) patients with and without nasal polyps (NPs), analyzed its association with disease severity and response to surgery, and explored its regulation via cytokines. METHODS The plasma and tissue CC10 levels were compared between controls and CRS patients with and without NPs by means of quantitative RT-PCR, ELISA, and immunohistochemistry. Computed tomography (CT) scan and endoscopy findings and symptoms were scored. Nasal explant culture was used to explore the effect of TNF-alpha, IL-1beta, IL-4, INF-gamma, and IL-10 on CC10 gene regulation. RESULTS Compared with controls, the CC10 expression in sinonasal mucosa was significantly inhibited in both CRS patients with and without NPs. There was a significant further decrease of CC10 expression in patients with NPs and asthma. No difference in CC10 plasma levels was found between controls and patients. CC10 levels inversely correlated with preoperative CT scores, and postoperative endoscopy and symptom scores. TNF-alpha, IL-1beta and IL-4 inhibited, whereas INF-gamma and IL-10 promoted CC10 production in nasal mucosa. A significantly faster decay of CC10 transcripts was seen after IL-1beta treatment. IL-1beta and IL-10 induced thyroid transcription factor-1 expression. INF-gamma increased, whereas IL-4 inhibited hepatocyte nuclear factor-3alpha expression. CONCLUSION CC10 may take part in the pathogenesis of CRS and correlates with disease severity and response to surgery. Different cytokines can regulate CC10 expression in nasal mucosa differentially through modulating mRNA stability and certain transcriptional factors expression.

Abstract
BACKGROUND Group II subfamily secretory phospholipases A(2) (sPLA(2)s) are the enzymes that can play a major role in inflammation. However, the presence of group II subfamily sPLA(2)s in human sinonasal mucosa and their roles in chronic rhinosinusitis (CRS) are not well known. The purpose of this study was to investigate the expression of group II subfamily sPLA(2)s in human sinonasal mucosa from controls and CRS patients with and without nasal polyps (NPs) and the regulation of expression by proinflammatory cytokines. METHODS Surgical samples were investigated by means of reverse transcriptase polymerase chain reaction (RT-PCR) for evaluation of group II subfamily sPLA(2)s mRNA expression, and the presence and location of group II subfamily sPLA(2)s-positive cells were analyzed by means of immunohistochemistry. Furthermore, nasal explant culture and quantitative RT-PCR techniques were used to investigate the effect of interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha on group II subfamily sPLA(2)s mRNA production in sinonasal mucosa. RESULTS Messenger RNA expression of sPLA(2)-IIA, -IID, and -IIE was significantly upregulated in tissues from CRS patients compared with control tissues. Among CRS patients, patients without NPs showed significantly stronger expression in sinonasal mucosa than patients with NPs of sPLA(2)-IIA mRNA, and weaker expression of sPLA(2)-IIE mRNA. Immunohistochemistry revealed enhanced protein expression of type II sPLA(2)s and specific type IIA sPLA(2) in epithelial cells and submucosal glands in samples from CRS patients. Stronger type IIA sPLA(2) protein expression was found in samples from CRS patients without NPs when compared with NPs. Nasal explant culture experiments demonstrated that mRNA expression of sPLA(2)-IIA, -IID, and -IIE was dramatically induced by IL-1beta and TNF-alpha. CONCLUSIONS The expression of some members of group II subfamily of sPLA(2)s is upregulated in CRS and it may result from IL-1beta and TNF-alpha overexpression. Different individual group II subfamily sPLA(2)s may play different roles in the pathogenesis of CRS with and without NPs.

Abstract
Several types of vegetables were collected from two contaminated sites in Tianjin, China. The bulk soil and the rhizosphere soil samples were also collected from the same plots. Sixteen PAHs in the samples were measured. The total concentrations of PAH16 in the bulk soil from the two sites were 1.08 and 6.25 microg/g, respectively, with similar pattern. The concentrations of PAH16 and individual compounds in the rhizosphere were significantly higher than those in the bulk soil with mean values of 2.25 and 7.82 microg/g for the two sites, respectively. The contents of both total and dissolved organic matter in the rhizosphere were also higher than those in the bulk soil. Almost all PAH compounds studied were detected in both roots and aerial parts of the vegetables studied. Abundance of higher molecular weight PAHs in vegetable, however, was lower than that in soil. Concentrations of PAH16 in vegetable were higher than those reported in the literature for other areas. It appears that agricultural soils and vegetables in Tianjin, especially those from the site located immediately next to an urban district and irrigated with wastewater for several decades, are severely contaminated by PAHs. Among the eight types of vegetable studied, the highest concentration of PAHs was found in cauliflower. By average, the concentration of PAH16 in the aerial part of vegetables was 6.5 times higher as that in vegetable root, suggesting that foliar uptake is the primary transfer pathway of PAHs from environment to vegetables.

Abstract
One hundred and eighty eight surface soil samples were collected from the Tianjin area to study the contamination of DDT and its metabolites. Measurements were taken for p,p'-DDE, p,p'-DDD, p,p'-DDT, o,p'-DDE, o,p'-DDD and o,p'-DDT for all samples. The results indicated that p,p'-DDT and p,p'-DDE were the predominant contaminant compounds in the surface soil samples, with mean concentrations of 27.5 and 18.8 ng g(-1) respectively. No significant differences in DDT concentrations were found between the soils from wastewater treated irrigated areas and other areas, suggesting that wastewater irrigation is not an important source of DDT in the area. However, the spatial distribution of soil DDTs levels in the area did correlate well with early direct application rates of pesticides. In addition, both pH level and organic carbon content are also known factors affecting the level of DDT and its metabolites. Although it was assumed that the use of these chemicals was banned in the early 1980s, the current concentration levels appear to be too high to be mere residuals after 20 years degradation.

Abstract
Human FPRL1 and its mouse homologue FPR2 are functional receptors for several exogenous and host-derived chemotactic peptides, including amyloid beta(42) (A beta(42)), a critical pathogenic factor in Alzheimer's disease. We investigated the effect of TNF alpha on the expression and function of FPR2 in mouse microglial cells, a crucial inflammatory cell type in the CNS. Primary murine microglia and a cell line N9 in resting state expressed low levels of FPR2 gene and lacked the response to chemotactic agonists for this receptor. Incubation with TNF alpha, however, increased microglial expression of FPR2 gene, in association with potent chemotactic responses to FPR2-specific agonists including A beta(42). The effect of TNF alpha was dependent on the p55 TNF alpha receptor and activation of MAP kinase p38. TNF alpha concomitantly down-regulated microglial response to the chemokine SDF-1 alpha. Thus, by selectively up-regulating FPR2 in microglia, TNF alpha has the capacity to amplify host response in inflammatory diseases in the CNS.

Abstract
A procedure was developed for determination of 16 polycyclic aromatic hydrocarbons (PAHs) in heavily contaminated paddy soil from wastewater irrigated farmland near Tianjin. The sample was distilled with accelerated solvent extraction (ASE), purified by a silica gel column, and measured with GC/MS. The optimal conditions for the distillation were at 140 degrees C (1500 psi) with a 1:1 mixture of dichloromethane and acetone for 5 min. Application of cyclohexane for extract transfer improved the recovery when the ASE extraction was followed by a silica gel cleanup procedure. Recoveries from the method for 16 PAHs ranged from 57-140% with the coefficients of variation of the results ranging from 0.35% to 5.75%. The total 16 PAHs in a composite sample collected from a wastewater irrigated paddy field near Tianjin was 3.90 mg/kg.

Abstract
Amyloid-beta, the pathologic protein in Alzheimer's disease, induces chemotaxis and production of reactive oxygen species in phagocytic cells, but mechanisms have not been fully defined. Here we provide three lines of evidence that the phagocyte G protein-coupled receptor (N-formylpeptide receptor 2 (FPR2)) mediates these amyloid-beta-dependent functions in phagocytic cells. First, transfection of FPR2, but not related receptors, including the other known N-formylpeptide receptor FPR, reconstituted amyloid-beta-dependent chemotaxis and calcium flux in HEK 293 cells. Second, amyloid-beta induced both calcium flux and chemotaxis in mouse neutrophils (which express endogenous FPR2) with similar potency as in FPR2-transfected HEK 293 cells. This activity could be specifically desensitized in both cell types by preincubation with a specific FPR2 agonist, which desensitizes the receptor, or with pertussis toxin, which uncouples it from G(i)-dependent signaling. Third, specific and reciprocal desensitization of superoxide production was observed when N-formylpeptides and amyloid-beta were used to sequentially stimulate neutrophils from FPR -/- mice, which express FPR2 normally. Potential biological relevance of these results to the neuroinflammation associated with Alzheimer's disease was suggested by two additional findings: first, FPR2 mRNA could be detected by PCR in mouse brain; second, induction of FPR2 expression correlated with induction of calcium flux and chemotaxis by amyloid-beta in the mouse microglial cell line N9. Further, in sequential stimulation experiments with N9 cells, N-formylpeptides and amyloid-beta were able to reciprocally cross-desensitize each other. Amyloid-beta was also a specific agonist at the human counterpart of FPR2, the FPR-like 1 receptor. These results suggest a unified signaling mechanism for linking amyloid-beta to phagocyte chemotaxis and oxidant stress in the brain.

Abstract
OBJECTIVE To investigate the diagnosis and management of the benign mesenchymoma in pharynx-esophagus. METHOD Records of 2 cases with the benign mesenchymoma, arising from the pharynx-esophagus, were reviewed. RESULT These tumors, their pedicle attached to the lateral pharynx or esophageal orifice and the body fall down to the esophagus, were large and solitary. Complete surgical resection is believed to be the most suitable treatment by lateral pharyngotomy. CONCLUSION The benign mesenchymoma in pharynx-esophagus is a rare disease which might be misdiagnosis. Diagnosis is based on typical histologic features as well as clinical information. The prognosis is favorable.

Abstract
AIM To investigate a simple method for assaying acrosin activity for the evaluation of male fertility. METHODS The acrosin activity of 7.5 x 10(6) sperm without seminal plasma and acrosin activity inhibitors was assayed using N-alpha-benzoyl-DL-arginine-p-nitroanilide (BAPNA) and detergent (Triton X-100) as substrate. RESULTS The acrosin activity of 60 normal fertile men (35 +/- 10 microIU/10(6) sperm ) was higher than that of 168 infertile men (16 +/- 8 microIU/10(6) sperm) (P < 0. 01). It was indicated that there was a significant positive correlation between the acrosin activity and the sperm motility (r > or = 0.6534, P < 0.01) and a significant negative correlation between the sperm malformed rate and the WBC number (r < or = -0.5426, P < 0.01). The temperature and time of incubation and the sperm concentration could influence the assay results. CONCLUSION Acrosin activity is an important index for the evaluation of male fertility. The approach developed by the authors is a simple method for the determination of acrosin activity.

Abstract
OBJECTIVE To discuss the influence of smoking on nasal airway resistance (NAR). METHOD The unilateral and total NAR of 40 normal controls, 41 slight smokers and 42 heavy smokers were evaluated by anterior rhinomanometry before and after nasal decongestion. RESULT Before nasal decongestion, the unilateral and total NAR of heavy smokers increased significantly (P < 0.05) compared with that of normal controls. After decongestion, there was no significant difference (P > 0.05). Whenever before or after decongestion, there was no significant difference between slight smokers and normal controls (P > 0.1). CONCLUSION Long-time and heavy smoking can enhance the NAR, which may be due to the chang of blood vessels in nasal mucosa.

Abstract
AIM To study the effects of dexamethasone (Dex), cyproheptadine (Cyp), anisodamine (Ani), and dinoprostone (Din) on lipopolysaccharides (LPS)-induced tumor necrosis factor alpha (TNF alpha) gene expression and antishock effects of inhibiting TNF alpha production. METHODS Endotoxic shock in rats was produced by i.v. injection of LPS (E coli O111B4, 5 mg.kg-1). TNF alpha mRNA accumulation was assessed by Northern blot. Plasma TNF alpha contents were determined by radioimmunoassay. RESULTS The TNF alpha mRNA levels in rat liver at 2 h after LPS challenge was increased obviously (autoradiograms analyzed by scanning were 38 +/- 10 vs saline control 11 +/- 8, P < 0.01). The plasma TNF alpha contents were markedly increased [(22 +/- 3) micrograms.L-1 vs saline control (2.2 +/- 1.0) micrograms.L-1, P < 0.01]. Dex 5, Cyp 5, Ani 10, or Din 2 mg.kg-1 immediately injected after i.v. LPS markedly decreased the TNF alpha mRNA levels in rat liver and plasma TNF alpha contents. The Dex, Cyp, Ani, and Din improved the mouse survival rate 24 h after LPS 20 mg.kg-1 challenge. CONCLUSION Dex, Cyp, Ani, and Din strongly inhibit LPS-induced TNF alpha gene expression, and have a beneficial antishock effects.

Abstract
The alcohol dehydrogenases (ADHs) and aldehyde dehydrogenases (ALDHs) that metabolize ethanol are polymorphic. Different alleles encode subunits of the enzymes that differ in their rate of metabolizing ethanol. These polymorphisms are distributed differently among populations and have been shown to influence the risk for alcoholism in some Asian populations. We have examined the allele frequencies at the ADH2, ADH3, and ALDH2 loci in four populations from China (Han, Mongolian, Korean, and Elunchun) and in alcoholics within each population. The four populations differ in allele frequencies, with the Elunchun having a much lower frequency of ADH2*2 alleles, and the Mongolian and Elunchun having a much lower frequency of ALDH2*2 alleles. Within each population, alleles at one or more of these three loci are protective against alcoholism, although the populations differ in which loci play significant roles. The protective allele at each locus (ALDH2*2, ADH2*2, and ADH3*1) encodes a subunit that either metabolizes ethanol to acetaldehyde more rapidly or slows the conversion of acetaldehyde to acetate. Taken as a whole, data demonstrate that genetic differences in the enzymes that metabolize alcohol can substantially affect the risk for alcoholism.

Abstract
Clones from a Frankia At4 gene bank were pooled into groups and mass conjugated into a nodD mutant of Rhizobium leguminosarum bv. viciae by triparental matings. When peas were inoculated with the pooled transconjugants, nodulation was observed. A plasmid, pAt2GX containing Frankia DNA, was isolated from bacteria recovered from these nodules. This plasmid was shown to complement a nodD mutant of R. leguminosarum bv. viciae. Thus pAt2GX contains a Frankia gene that is functionally equivalent to nodD of R. leguminosarum bv. viciae.
