Abstract
BACKGROUND We aimed to compare combined intraoperative chemotherapy and surgical resection with curative surgical resection alone in colorectal cancer patients. METHODS We performed a multicenter, open-label, randomized, phase III trial. All eligible patients were randomized and assigned to intraoperative chemotherapy and curative surgical resection or curative surgical resection alone (1:1). Survival actualization after long-term follow-up was performed in patients analyzed on an intention-to-treat basis. RESULTS From January 2011 to January 2016, 696 colorectal cancer patients were enrolled and randomly assigned to intraoperative chemotherapy and radical surgical resection (n=341) or curative surgical resection alone (n=344). Intraoperative chemotherapy with surgical resection showed no significant survival benefit over surgical resection alone in colorectal cancer patients (3-year DFS: 91.1% vs. 90.0%, P=0.328; 3-year OS: 94.4% vs. 95.9%, P=0.756). However, colon cancer patients benefitted from intraoperative chemotherapy, with a relative 4% reduction in liver and peritoneal metastasis (HR=0.336, 95% CI: 0.148-0.759, P=0.015) and a 6.5% improvement in 3-year DFS (HR=0.579, 95% CI: 0.353-0.949, P=0.032). Meanwhile, patients with colon cancer and abnormal pretreatment CEA levels achieved significant survival benefits from intraoperative chemotherapy (DFS: HR=0.464, 95% CI: 0.233-0.921, P=0.029 and OS: (HR=0.476, 95% CI: 0.223-1.017, P=0.049). CONCLUSIONS Intraoperative chemotherapy showed no significant extra prognostic benefit in total colorectal cancer patients who underwent radical surgical resection; however, in colon cancer patients with abnormal pretreatment serum CEA levels (> 5 ng/ml), intraoperative chemotherapy could improve long-term survival.

Abstract
Objective: To investigate the effect of plasminogen activator urokinase receptor (PLAUR) gene on neutrophil activation and apoptosis in neutrophil-like cell model. Methods: Human acute myeloid leukemia cell line HL60 was cultured in vitro and induced to differentiate into neutrophil-like cells by all-trans retinoic acid (ATRA). Lentiviral vectors interfering with human PLAUR gene was constructed and transfected into neutrophil-like cells (siRNA group). The phosphate buffer saline (PBS) group (untransfected neutrophil-like cells) and normal blank control group (NC group) (neutrophil-like cells transfected with blank plasmid) were used as controls (n=3). After starvation culture and addition of interleukin-17 afterwards in these 3 groups, the expression of CD11b on the cell membrane was detected by flow cytometry, and the levels of myeloperoxide (MPO) and extracellular neutrophil traps (NETs) in the supernatant were detected by enzyme-linked immunosorbent assay (ELISA) to investigate the activation of neutrophil-like cells. The apoptosis was detected by flow cytometry with annexin V/propidium iodide (PI) double staining and the expressions of apoptosis-related proteins caspase-3, bax and bcl-2 were detected by Western blotting. Results: The expression of CD11b in siRNA group (32.37±8.17) was lower than that in PBS group (46.27±1.54) and NC group (53.07±8.14) (P<0.05) by flow cytometry. The levels of MPO and NETs (33.37±1.11, 57.69±3.03) in the supernatant of siRNA group were significantly lower than those in PBS group (41.64±2.20, 77.60±4.33) and NC group (40.84±5.11, 76.15±2.10) (P<0.05). Flow cytometry with annexin V/PI showed that the expression of apoptosis in siRNA group (20.42%±2.45%) was significantly higher than that in PBS group (11.91%±2.23%) and NC group (11.13%±2.56%) (P<0.05). The relative expression of caspase-3 protein and bax protein (0.84±0.05, 0.83±0.04) in siRNA group was significantly higher than that in PBS group (0.68±0.02, 0.63±0.08) and NC group (0.71±0.01, 0.66±0.10) (P<0.05), and the relative expression of anti-apoptosis protein bcl-2 decreased in siRNA group (0.38±0.02) than in PBS group (0.73±0.05) and NC group (0.69±0.06) (P<0.05). Conclusion: PLAUR promotes the activation of neutrophil-like cells and inhibits the apoptosis.

Abstract
Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Abstract
Recent advances in multimodality treatment offer excellent opportunities to rethink the paradigm of perioperative management for locally advanced esophageal squamous cell carcinoma. One treatment clearly doesn't fit all in terms of a broad disease spectrum. Individualized treatment of local control of bulky primary tumor burden (advanced T stage) or systemic control of nodal metastatic tumor burden (advanced N stage) is essential. Given that clinically applicable predictive biomarkers are still awaited, therapy selection guided by diverse phenotypes of tumor burden (T vs. N) is promising. Potential challenges regarding the use of immunotherapy may also boost this novel strategy in the future.

Abstract
Esophageal carcinoma is one of the most common malignant tumors in the world, with incidence and mortality rankings of 7th and 6th, respectively. In recent years, immunotherapy represented by immune checkpoint inhibitors of programmed death-1 and programmed death ligand 1 (PD-L1) has been introduced into clinical practice and has changed the treatment status of esophageal cancer. Although immunotherapy has provided long-term survival benefits for patients with advanced esophageal cancer and high pathological response rates in the neoadjuvant therapy, only a few of the patients have satisfactory therapeutic outcomes. Therefore, effective biomarkers for predicting immunotherapeutic effects are urgently needed to identify those patients who could benefit from immunotherapy. In this paper, we mainly discuss recent research advances of biomarkers related to the immunotherapy of esophageal cancer and the clinical application prospects of these biomarkers.

Abstract
213 Background: Identifying molecular residual disease (MRD) with tailored tumor-informed ctDNA-based next-generation sequencing (NGS) assays after curative surgery could facilitate the individualized management of resected colorectal cancer (CRC) patients. Here, we prospectively evaluated the clinical performance of tumor-informed ctDNA mutation analysis using a novel Burning Rock Patient-specific Prognostic and Potential Therapeutic Marker Tracking (brPROPHET) approach for assessing MRD in resected CRC patients. Methods: The brPROPHET assay was designed to track patient-specific somatic variants based on whole-exome sequencing (WES) of the tumor tissue and matched white blood cells (WBCs). Fixed panel with informed calling (FI) and fixed panel with agnostic calling (FA) assays were performed in a subset of patients with a 168-gene panel spanning 273 kb of the human genome for a head-to-head comparison. Results: A total of 117 patients (stage II/III 53[45.0%]/41[35.0%]) were analyzed. 60 (51.0%) patients were treated with adjuvant therapy after surgery. brPROPHET assay was designed to target up to 55 variants per patient. Only 6% (344/5835) of designed variants were included in the fixed panels. 75% (2908/3886) of genes selected for panel design were private to a specific patient. Preoperative ctDNA was detected in 97% (113/117) of the patients with 88% (14/16), 98% (52/53), 98% (40/41), and 100% (7/7) in stage I, II, III and IV, respectively. The median ctDNA levels were observed to be higher in patients with advanced stages and significantly correlated with tumor volume. MRD status was tested postoperatively on day 7 and day 30 with a positivity rate of 18% (21/117) and 15% (14/93), respectively. Due to a short follow-up period, only two patients had recurred, and ctDNA was detected prior to radiological relapse, with a lead time of 1 and 2 months, respectively. Among 74 patients enrolled for parallel comparing three MRD assays, preoperative ctDNA was detected in 97.3%, 75.7%, and 68.9% of patients with brPROPHET, FI and FA fixed panel assays, respectively. 20.3% (15/74) of patients had baseline ctDNA captured by brPROPHET assay only. The ctDNA levels of these patients (median:0.3 mean tumor molecules [MTM] / milliliter [mL]) were lower than those captured by FI/FA fixed panels (median:3.0 MTM/mL, p<0.05). A total of 135 postoperative blood samples were tested by all three assays, the positive rates with brPROPHET, FI and FA fixed panel assays were 14.8%, 8.1%, and 6.7% respectively. Conclusions: This initial study reported the clinical performance of the patient-specific brPROPHET assay in CRC, demonstrating superior sensitivity in detecting preoperative and postoperative ctDNA than the fixed panel assays. The ongoing study including correlation with clinical outcomes and serial testing will be presented.

Abstract
Objective: To summarize the clinical experience and treatment results of endoscopic transoral resection of metastatic retropharyngeal lymph nodes (MRPLN) in nasopharyngeal carcinoma (NPC) via posteroinferior eustachian tube approach. Methods: The clinical data of 37 patients with NPC who underwent endoscopic transoral surgery via posteroinferior eustachian tube approach for MRPLN in Xuanwu Hospital, Capital Medical University from 2010 to 2020 were analyzed retrospectively. There are 28 males and 9 females, aged from 31 to 72 years. The clinicopathological features such as gender, age, primary tumor stage, stage, side and size of MRPLN were recorded and analyzed. The surgical procedures of endoscopic transoral resection of MRPLN via posteroinferior eustachian tube approach were described. The MRPLN resection, perioperative complications and follow-up results were also summarized. Results: The primary tumors of 37 cases were determined as rT1 stage in 2 cases, rT2 stage in 30 cases and primary T2 stage in 5 cases in this study. There were 33 cases of unilateral MRPLN(89.2%), 4 cases of bilateral ones (10.8%), 36 cases in N1 stage, and 1 case in N3 stage. Single lymph node was detected in 23 cases(62.2%), and 2-5 lymph nodes in 14 cases(37.8%). Endoscopic transoral surgery via posteroinferior eustachian tube approach was completed in all cases. Total MRPLN resection was obtained in 35 cases (94.6%) with one-stage operation, and subtotal resection was achieved in 2 cases whose MRPLN involved the wall of internal carotid artery. No serious complications occurred in the perioperative period. During the follow-up period (median follow-up period 53.1 months), no recurrence of MRPLN was observed in patients who received total resection. And 8 patients (21.6%) died from different causes. Conclusion: Endoscopic transoral surgery via posteroinferior eustachian tube approach for MRPLN is a practicable and effective surgical option, but the long-term effect still needs longer follow-up and summary of bulk cases.

Abstract
Objective: To investigate the effects of ursolic acid (UA) on oxidative stress and inflammatory factors in a rat model of AR after PM2.5 exposure. Methods: Sixty healthy female SD rats were randomly divided into five groups: normal control group (NC group), PM2.5 unexposed AR group (AR group), PM2.5 exposed AR group (ARE group), UA intervention AR group (AR+UA group), and UA intervention PM2.5 exposed AR group (ARE+UA group), with 12 rats in each group. AR model was performed by a basal sensitization with intraperitoneal injection of ovalbumin (OVA) and followed by nasal instillation. PM2.5 exposure was carried out by inhalation exposure system at a concentration of 200 μg/m3 for 3 h/d for 30 days. UA intervention group was given UA intragastric administration at 20 mg/(kg·d). AR symptoms including sneezing, nasal scratching and nasal secretion of rats in each group were observed. The activities of superoxide dismutase (SOD) and the level of malondialdehyde (MDA) in nasal mucosa were tested. The pathological changes of nasal mucosa were observed by HE staining. The levels of OVA-sIgE, IL-6 and IL-17 in serum were measured by enzyme-linked immunosorbent assay (ELISA). Protein microarray was used to measure the expression of multiple inflammation cell factors in nasal mucosa. Statistical analysis was performed with SPSS 20.0. Results: After UA intervention, the frequency of nasal sneezing, scratching and nasal secretion in ARE+UA group were lower than those of ARE group (P<0.05). Pathological examination of nasal mucosa showed that ARE+UA group had less inflammatory granulocyte infiltration and less pathological damage to the epithelial layer than ARE group. The activities of SOD in nasal mucosa of ARE+UA group were higher than those of ARE group ((50.10±3.09) U/mg vs (20.13±1.30) U/mg, F value was 597.54, P<0.01). The contents of MDA in nasal mucosa of ARE+UA group were lower than those of ARE group ((57.78±12.36) nmol/g vs (124.12±9.40) nmol/g, F value was 115.51, P<0.01). The expression levels of OVA-sIgE, IL-6 and IL-17 proteins were lower in the ARE+UA group than those in ARE group ((11.61±0.27) ng/ml vs (20.30±0.67) ng/ml, (47.59±15.49) pg/ml vs (98.83±10.98) pg/ml, (623.30±8.75) pg/ml vs (913.32±9.06) pg/ml, F value was 283.42, 80.45, 683.73, respectively, all P<0.01). After UA intervention, protein microarray analysis showed that the expression of IL-4, IL-6, IL-13, chemokine CXCL7, IL-1α, IL-1β, MMP-8 and MCP-1 in ARE+UA group was decreased compared with ARE group while IFN-γ and IL-10 increased (all P<0.01). Conclusion: UA can reduce the aggravated AR symptoms and pathological damage of nasal mucosa, inhibit oxidative stress and release of inflammatory factors after PM2.5 exposure, and thus plays a protective role in the pathological damage of AR induced by PM2.5 exposure.

Abstract
p-Nitrophenol is usually present in ammonia-rich wastewaters produced by some chemical plants. In this work, the response of anammox process to long-term p-nitrophenol stress was investigated. The changes in the efficiency, sludge characteristics, and microorganisms of the anammox system under different levels of p-nitrophenol stress were examined, and the potential stress mechanisms of p-nitrophenol on anammox were further speculated. The results showed that 10-50 mg/L p-nitrophenol had no obvious impact on nitrogen removal efficiency, but stimulated the secretion of more extracellular polymeric substances. 60 mg/L p-nitrophenol caused the nitrogen removal efficiency to decrease by 64.5% in 5 days. Long-term exposure to p-nitrophenol led to 8.6% reduction in Candidatus_Kuenenia abundance and 18.4%-35.9% decrease in the expression level of anammox bacterial functional genes. Molecular simulation indicated that p-nitrophenol could bind to key enzymes of anammox. This study provides new insights into the treatment of wastewater containing p-nitrophenol or phenol by anammox.

Abstract
Objective: To evaluate the characteristics of MRI T2 value changes of muscles around the knee joint in amateur marathon athletes based on T2 mapping. Methods: A total of 12 amateur marathon runners (5 males and 7 females) were recruited as the marathon group, aged from 21 to 37(27.5±5.4) years. MRI examination of bilateral knee joint was performed one week before the race, within 12 hours after the race and two months after the race, respectively. Fifteen healthy volunteers (5 males and 10 females) were recruited as the control group, aged from 24 to 27(24.9±1.0) years, and underwent MRI examination of both knee joints. The T2 mapping imaging sequence was used to measure the T2 values of the sartorius, vastus medialis, biceps femoris, semimembranosus, medial head of gastrocnemius and lateral gastrocnemius head on the post-processing platform, and analyzed the marathon group before and after the race. The differences in the T2 value of each muscle of the marathon group before and after the race within 12 hours, before and 2 months after the race, and between the control group and the marathon group before the marathon were analyzed. Results: All subjects had not knee joint pain during the examination. Routine MRI examination showed that there was no obvious abnormality in the shape and signal of the muscles around the knee joint. The T2 value of the semimembranosus [(34.3±2.8) ms vs (35.5±2.5) ms, P=0.008], medial head of gastrocnemius [(34.1±3.4) ms vs (37.7±3.1) ms,P<0.001] and lateral head of gastrocnemius [(35.2±2.9) ms vs (37.2±3.9) ms,P=0.011] increased after the competition compared with that of pre-competition in the marathon group, while the T2 value of the remaining muscles showed no significant difference compared with that of pre-competition(P>0.05). At the follow-up of 2 months, the T2 value of semimembranosus remains higher than before the marathon [(34.3±2.8) ms vs (35.4±2.5) ms,P=0.043], and the T2 value of the medial head of the gastrocnemius and lateral head of gastrocnemius showed no statistically difference compared with pre-competition (P>0.05). Compared with the control group, the T2 value of the lateral head of the gastrocnemius in the marathon group was decreased [(35.3±3.0) ms vs (38.5±4.1) ms,P=0.007]. There was no significant difference in the T2 value of the remaining muscles in the marathon group (P>0.05). Conclusions: After the marathon, the changes in the T2 value of the muscles around the knee joint is reversible. T2 mapping imaging sequence can indirectly reflect the changes of skeletal muscle microstructure to a certain extent.

Abstract
117 Background: The benefit of adding Oxaliplatin to neoadjuvant chemoradiotherapy in Locally Advanced Rectal Cancer (LARC) patients remains controversial. The present study investigated whether induction chemotherapy (CapOX), 2 cycles of CapOX combined with standard radiation (Oxa-CRT) concurrently and consolidation chemotherapy (CapOX) could improve OS compared with standard treatment (nCRT) for locally advanced rectal cancer. Methods: We conducted this randomized, single center, open-label, phase III trial in China. Eligible patients were pathologically confirmed rectal adenocarcinoma, clinical T3-4 with or without regional N + and no sign of distance metastasis determined by pelvic MRI, chest and abdominal CT scan. All patients were randomly allocated to the experimental group: pelvic radiation of 50Gy/25 fractions with 4 cycles of oxaliplatin and capecitabine (1 cycle of CapOX (oxaliplatin: 130mg/m2, cape: 1000mg/m2, bid, Day 1 to Day 14) administrated before radiotherapy as induction chemotherapy, 2 cycles of CapOX (oxaliplatin: 100mg/m2, cape: 1000mg/m2, bid, Day 1 to Day 14) administrated concurrent with RT, and 1 cycle of CapOX (oxaliplatin: 130mg/m2, cape: 1000mg/m2, bid, Day 1 to Day 14) conducted as consolidation chemotherapy); or control group: radiation with capecitabine. The primary end point was OS. This trial was registered with ClinicalTrials.gov (ClinicalTrials.gov identifier: NCT02031939). Results: From January 2014 to June 2020, 556 patients enrolled in this study (n=278 in both groups), and 536 patients were evaluable (269 in experimental group and 267 patients in control group). Surgery was performed in 235 patients (84.5%) in experimental group and 242 patients (87.1%) in control group. The pCR rates were 27.8% (75 in 269) and 19.4% in control group (52 in 267) (p = 0.025). 16 and 5 patients achieved clinical complete response (cCR) in experimental and control group, respectively. Grade 3-4 toxicities were recorded in 42 (21.8%) and 6 (5.1%) patients in experimental and control group. The most common grade 3-4 toxicities were leukopenia, thrombocytopenia and neutropenia. The overall surgical complication rate was not significantly different between two groups (12.1% vs. 11.9%). Conclusions: Four cycles of CapOX combined with RT in LARC significantly increased complete tumor response in Chinese patients with acceptable toxicities. Clinical trial information: NCT02031939.

Abstract
The oligometastatic and oligoprogressive state has been a hot issue in cancer research. Its indolent tumor behavior, representing a novel therapeutic opportunity, has been identified as a clinical subtype in several malignancies. However, the clinical implications of the oligometastatic and oligoprogressive state in esophageal squamous cell carcinoma (ESCC) have not been thoroughly elucidated. There are still controversies regarding the existence of the oligometastatic state in ESCC, if the solitary regional lymph node metastasis should be viewed as oligoprogressive disease after esophagectomy, and the role of surgery and radiotherapy in ESCC oligometastatic disease. Despite many exciting contributions to the literature on these, further exploration is warranted. Thus, fostering the advance of research and scientific knowledge on the biological and prognostic characteristics scrupulously would facilitate personalizing treatment strategy for better outcomes.

Abstract
e15602 Background: Immunotherapy has shown satisfactory effect for dMMR/MSI-H colorectal cancer patients. Whether Pd-1 antibody would bring benefit for dMMR/MSI-H locally advanced rectal cancer (LARC) patients in neoadjuvant setting is worthy of investigation. This is a clinical trial with two cohorts according the MMR/MSI status(clinicalTrials.gov, NCT04304209). Methods: LARC patients with dMMR or MSI-H tumor will enter Cohort A and receive neoadjuvant Pd1 antibody sintilimab for four cycles and subsequent surgery or watch and wait, followed by adjuvant four cycles of Pd1 antibody sintilimab with or without chemotherapy. Main inclusion criteria include: cT3-4N0M0 or cTxN+M0 rectal adenocarcinoma, dMMR/MSI-H confirmed by immunohistochemistry (IHC) or gene test, aged 18-75y; ECOG performance 0-1; no previous anti-tumor treatment for rectal adenocarcinoma. Primary outcome is pathologic complete response (pCR) rate. We use a Simon two-stage optimum design to test the null hypothesis of a 15% pCR rate, the historical response rate to standard neoadjuvant chemoradiotherapy (NACRT), against the desired alternative of 30% pCR rate. This had a one-sided type I error of 5% and a power of 80%. In the first stage of this design, 19 patients will be accrued. If 3 or fewer pCR was observed, the study was to be terminated and declared negative. If the trial goes on to the second stage, a total of 55 patients will be studied. The study was deemed to have met its primary endpoint if confirmed pCR were observed in 13 or more patients. Considering 10% dropout rate, a total of 61 patients will be enrolled. Whole exome sequencing, bulk RNA sequencing, single cell RNA sequencing and IHC of the rectal primary tumor are planned. The study started in October, 2019. Results: Eight patients have been enrolled and six have response evaluation results. Four patients achieved clinical complete response (cCR) after 4 cycles of neoadjuvant Pd1 antibody sintilimab treatment and three of them enter watch and wait strategy and finished the adjuvant 4 cycles of Pd1 antibody sintilimab treatment. The 4th patient was diagnosed as lynch syndrome, but molecular test was not feasible for the tumors located at the sigmoid and hepatic flexure because of ileus. He received subtotal colectomy and tumors at the sigmoid and hepatic flexure also achieved pCR. The 5th patient has partial response after 4 and 8 cycles of sintilimab treatment, and then received Dixon surgery and pathology showed major reponse (5% cancer cell left only in the mucosal layer, ypTis). The 6th patient has partial response after 4 and 8 cycles of sintilimab treatment, and sintilimab was still continued concerning intact bladder conservation. No grade 3 toxicity was noted yet. Conclusions: Pd1 antibody sintilimab achieved 4CR (pCR+cCR) in 6 dMMR/MSI-H LARC patients with limited toxicities. Pd1 antibody is quite effective and may be an alternative for these patients. Clinical trial information: NCT04304209.

Abstract
Background CKLF-like MARVEL transmembrane domain-containing 6 (CMTM6), a programmed death-ligand 1 (PD-L1) regulator, is widely expressed in various tumors and regulates the immune microenvironment. However, its prognostic value remains controversial, and the roles of CMTM6 in colorectal cancer (CRC) are still unknown. In this study, we aimed to elaborate the expression patterns of CMTM6 and PD-L1 in CRC and investigate their relationship with the infiltration of T cells and the prognosis of patients with CRC. Methods Analysis of CMTM6 mRNA levels, gene ontology enrichment analysis and single-sample gene set enrichment analysis were performed in a The Cancer Genome Atlas colon cancer cohort. The expression of CMTM6 and PD-L1 and the infiltration of T cells in tumor tissues from our cohort containing 156 patients with CRC receiving adjuvant chemotherapy and 77 patients with CRC without chemotherapy were examined by immunohistochemistry
assay. Results CMTM6 expression was upregulated in CRC compared with normal colon tissues, and CMTM6 levels were lower in advanced tumors than in early-stage tumors. High expression of CMTM6 correlated with lower pT stage and more CD4+/CD8+ tumor-infiltrating lymphocytes (TILs) and predicted
a favorable prognosis in CRC. PD-L1 was expressed in CRC tissues at a low level, and PD-L1 positivity in tumor stroma (PD-L1(TS)), but not PD-L1 positivity in cancer cells (PD-L1(CC)), was associated with an increased density of CD4+ TILs and a favorable prognosis. The coexpression status of CMTM6 and PD-L1(TS) divided patients with CRC into three groups with low, moderate and high risks of progression and death, and patients with CMTM6High/PD-L1(TS)+ status had the longest survival. Moreover, the prognostic value of CMTM6/PD-L1 expression was more significant in patients with CRC treated with adjuvant chemotherapy than in those not treated with chemotherapy. Conclusion CMTM6 has a critical impact on the immune microenvironment and can be used as an independent prognostic factor for CRC. The coexpression status of CMTM6 and PD-L1 can be used as a new classification to stratify the risk of progression and death for patients with CRC, especially for patients receiving adjuvant chemotherapy. These findings may provide insights into improving responses to immunotherapy-included comprehensive treatment for CRC in the future.

Abstract
This study aimed to investigate the relationship between bone quality in terms of metabolism, homeostasis of elements, bone mineral density (BMD), and microstructure and keel-bone fractures in laying hens (Gallusgallusdomesticus). One hundred and twenty 17 week old Lohmann White
laying hens with normal keel bones were individually housed in furnished cages for 25 weeks. Birds were then euthanased and dissected to assess keel-bone status at 42 weeks. Serum and keel-bone samples from normal keel (NK) and fractured keel (FK) hens were collected to determine the previously
mentioned bone quality parameters. The results showed FK hens to have higher levels of the components of osteocalcin, greater alkaline phosphatase activity in serum and keel bones, and greater tartrate-resistant acid phosphatase (TRAP) activity in keel bones, compared to NK hens. Additionally,
FK hens also had higher concentrations of Li, B, K, Cu, As, Se, Sn, Hg, and Pb, but lower concentrations of Na, P, and Ca. Moreover, FK hens showed decreased bone microstructural parameters including bone volume/tissue volume, trabecular number, degree of anisotropy, connectivity density,
and BMD, but increased trabecular separation. Meanwhile, no differences were detected in serum TRAP activity, trabecular thickness, bone surface, or bone surface/bone volume. Results showed laying hens with keel-bone fractures to have differences in bone metabolism, elements of homeostasis,
bone microstructure parameters, and BMD. These results suggest that keel-bone fractures may be associated with bone quality.

Abstract
Background Hepatocellular carcinoma (HCC) is a major health problem and a primary cause of cancer‐related death worldwide. Although great advances have achieved recently by large‐scale high‐throughput analysis, the precise molecular mechanism underlying HCC progression remains to be clearly elucidated. We investigated the relationship between Tescalcin (TESC), a candidate oncogene, and clinicopathological features of HCC patients and explored the role of TECS in HCC development. Methods To identify new genes involved in HCC development, we analyzed The Cancer Genome Atlas liver cancer database, and TESC was selected for further investigation. HCC tissue microarray analysis for TESC and its association with clinicopathological features were performed to investigate its clinical significance. TESC was knocked down by using short‐hairpin RNAs. Cell proliferation was analyzed by WST‐1 assay and cell counting. Cell apoptosis was tested by fluorescence‐activated cell sorting. A subcutaneous xenograft tumor model in nude mice was established to determine the in vivo function of TESC. Affymetrix microarray was used to identify its molecular mechanism. Results TESC was significantly increased in HCC tissues compared with the adjacent normal liver tissues. High expression of TESC was detected in 61 of 172 HCC patients by tissue microarray. Large tumor (> 5 cm) and elevated total bilirubin were associated with high TESC expression (both P < 0.050). In multivariate analysis, TESC was identified as an independent prognostic factor for short overall survival of HCC patients. TESC knockdown impaired HCC cell growth in vitro and in vivo. TESC knockdown significantly increased cell apoptosis in HCC cell lines. Furthermore, Affymetrix microarray analysis revealed that TESC knockdown inhibited tumor proliferation‐related pathways while activated cell death‐related pathways. Conclusion TESC was identified as an independent prognostic factor for short overall survival of HCC patients, and was critical for HCC cell proliferation and survival.

Abstract
Skin toxicity, especially hand-foot syndrome (HFS), is one of the most common sorafenib-induced adverse events (AEs) in hepatocellular carcinoma (HCC) patients, leading to treatment interruption and failure. Mucocutaneous inflammation may cause HFS; therefore, we investigated whether celecoxib can alleviate HFS, improve patients' quality of life and increase survival when administered in conjunction with active therapy. Our randomized, open-label study prospectively enrolled 116 advanced HCC patients receiving sorafenib as targeted therapy from July 2015 to July 2016. All patients were randomly assigned (1:1) via a computer-generated sequence to receive sorafenib with or without celecoxib. Sorafenib-related AEs were recorded, Survival was compared between the two groups. Compared to the Sorafenib group, the SoraCele group had lower incidence rates of ≥ grade 2 and grade 3 HFS (63.8% vs 29.3%, P < 0.001; 19.0% vs 3.4%, P = 0.008, respectively), hair loss, rash and abdominal pain. Kaplan-Meier analysis revealed a lower risk of ≥ grade 2 HFS (HR, 0.384; P = 0.002) and a lower dose reduction/interruption rate (46.6% to 15.5%, P < 0.001) in the SoraCele group. Cox proportional hazards regression analysis demonstrated that celecoxib was the only independent predictive factor of developing ≥ grade 2 HFS (HR, 0.414; P = 0.004). Longer progression-free survival (PFS) was also observed in the SoraCele group (P = 0.039), although overall survival was not prolonged (P = 0.305). These results suggest that sorafenib + Celecoxib administration alleviated sorafenib-related skin toxicity. Longer PFS was achieved in clinical practice, although overall survival was not prolonged (ClinicalTrials.gov: NCT02961998).

Abstract
Objective: To explore the differences in epidemiology and clinical features of Guillain- Barré syndrome (GBS) between rural and urban areas of southern China. Methods: The clinical data of 759 hospitalized GBS patients from 31 hospitals of 13 provinces/cities in southern China, between January 1st, 2013 and September 30th, 2016, were collected and analyzed retrospectively. Results: The risk of GBS was higher for males than females in rural and urban areas and the median age was 49 and 48 years, respectively. Seasonal clustering in winter and spring was noted in both rural and urban areas, and the seasonal trend was more markedly in rural areas, but the differences showed no statistical significance. There were 70.37% of patients in rural areas and 73.69% in urban areas who had antecedent respiratory infection. The median time from onset to nadir was 7 days, and Hughes Disability Scale at admission, nadir and discharge were (2.95±1.10 vs 2.84±1.15), (3.25±1.11 vs 3.14±1.21), (2.02±1.24 vs 2.00±1.31) in rural and urban areas respectively. Albuminocytologic dissociation was present in 84.34% of patients in rural areas and 84.62% of cases in urban areas. There were 8.65% and 10.94% of cases in rural and urban areas who required mechanical ventilation during hospitalization, respectively. Demyelinating GBS accounted for 53.29% and 48.77%, respectively, in patients with findings of nerve conduction studies available in rural and urban areas. Conclusions: GBS in rural areas of southern China showed male predominance and a peak of spring and winter occurrence, with respiratory infection as the predominated preceding events and demyelinating GBS being main clinical subtype. Winter and spring showed a higher incidence of GBS in rural and urban areas. There were no significant differences of sex, age, preceding events, season trend, progression of disease, clinical subtypes and cerebrospinal fluid investigations in GBS patients between rural and urban areas.

Abstract
Chemoradiotherapy combined with surgical resection is the standard treatment for locally advanced rectal cancer, but not all the patients respond to neoadjuvant treatment. Transforming acidic coiled-coil protein-3 (TACC3) is frequently aberrantly expressed in rectal cancer tissue. In this study, we investigated whether TACC3 could serve as a biomarker predictive of the efficacy of chemoradiotherapy. In all, 152 rectal cancer patients with tumor tissue collected at biopsy and set aside before treatment were enrolled in this study. All patients received chemoradiotherapy and surgical resection. Immunohistochemically detected tumoral TACC3 expression significantly decreased sensitivity to chemoradiotherapy [risk ratio (RR) = 2.236, 95% confidence interval (CI): 1.447-3.456; P = 0.001] and thus the pathological complete response rate (P = 0.001). TACC3 knockdown using specific siRNA enhanced radiotherapy-induced decreases in proliferation and colony formation by HCT116 and SW480 cells and increased the incidence of radiotherapy-induced apoptosis. Cox multivariate analysis showed that TACC3 was a significant prognostic factor for overall survival (P = 0.017) and disease-free survival (P = 0.020). These findings suggest TACC3 expression may be predictive of chemoradiotherapy sensitivity and prognosis in locally advanced rectal cancer.

Abstract
Objective: To explore the role of autophagy in PM2.5-induced inflammation in human nasal epithelial cells and related mechanism. Methods: Human nasal epithelial cells were exposed to different concentration of PM2.5 for different times, and the expression levels of microtubule-associated protein-1 light chain-3 Ⅱ (LC3 Ⅱ) and Beclin1 proteins were measured by Western blot. The typical autophagosome and autolysosome were observed by using transmission electron microscopy (TEM). To observe autophagic flux, mRFP-GFP-LC3 plasmid was transfected to nasal epithelial cells and the punctate staining of mRFP-GFP-LC3 were determined by confocal laser scanning microscope. The expression of inflammatory cytokines interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α) in cell culture supernatant were assessed by enzyme-linked immunosorbent assay (ELISA). To assess the role of autophagy in PM2.5-mediated inflammation, autophagy related gene Atg5 and Beclin-1 were silenced by siRNA knockdown, and inflammatory cytokines were analyzed.GraphPad Prism 6.0 was used for statistical analysis. Results: PM2.5 exposure increased the expression of LC3 Ⅱ and Beclin-1 proteins in a dose- (in PM2.5 group with concentration of 0, 15, 30, 60, 120 μg/ml, the expression of LC3 Ⅱ was 0.021±0.001(x±s), 0.037±0.002, 0.058±0.005, 0.075±0.006, 0.085±0.004, respectively, F=126.8, P<0.05; the expression of Beclin-1 was 0.002±0.000, 0.003±0.000, 0.005±0.000, 0.007±0.001, 0.008±0.001, respectively, F=137.3, P<0.05) and time-dependent manner (in PM2.5 group with exposure time of 0, 3, 6, 12, 24 h, the expression of LC3Ⅱ was 0.160±0.007, 0.222±0.003, 0.251±0.015, 0.483±0.029, 0.585±0.035, respectively, F=215.3, P<0.05; the expression of Beclin-1 was 0.059±0.002, 0.080±0.002, 0.087±0.002, 0.183±0.007, 0.228±0.005, respectively, F=137.3, P<0.05) in human nasal epithelial cells. TEM analysis showed typical autophagosome and autolysosome in cells after PM2.5 exposure for 24 h. PM2.5 significantly increased the number of yellow and red dots representing autophagosomes and autolysosomes respectively, indicating autophagic flux was elevated. Moreover, PM2.5 enhanced the secretion of inflammatory cytokines such as IL-6 and TNF-α, which was dramatically prevented by Atg5-siRNA and Beclin-1-siRNA. Conclusion: Autophagy plays an important role in PM2.5-caused inflammation response in nasal epithelial cells, which can induce release of inflammatory factors such as IL-6 and TNF-α and advance the inflammatory reaction.

Abstract
Objective: To investigate the effect of PM2.5 exposure on nasal inflammatory cytokines and nasal mucosal pathology in a rat model of allergic rhinitis (AR). Methods: Twenty-four healthy female SD rats were randomly divided into 3 groups by random number table method, with 8 rats in each group: normal control group (NC group), ovalbumin (OVA) induced AR model (AR group), and AR model group inhaled to PM2.5 at 200 μg/m(3), 3 h/d, for 30 d (ARE group). Nasal symptoms including sneezing, nasal rubs and nasal secretion were recorded. Levels of OVA specific IgE in serum, interleukin 6 (IL-6) and tumor necrosis factor-ɑ (TNF-ɑ) in nasal irrigating solution were measured by enzyme-linked immunosorbent assay (ELISA). The histopathological changes of nasal mucosa were observed by HE staining. SPSS 17.0 software was used to analyze the data. Results: The number of sneezing, nasal rubs and the amount of nasal secretion in the ARE group were significantly higher than that in the AR group and the NC group (number of sneezing (15.38±1.68) times/15 min vs (11.63±1.13) times/15 min vs (1.75±0.71) times/15 min, number of nasal rubs (27.75±2.12) times/15 min vs (21.25±2.96) times/15 min vs (5.25±1.04) times/15 min, amount of nasal secretion (18.90±2.07) mg vs (13.83±1.81) mg vs (3.78±0.41) mg, F values was 236.089, 224.139, 183.971, respectively, all P<0.001). Statistically significant differences in OVA specific IgE, IL-6 and TNF-ɑ levels were observed in ARE group exceeded AR group and NC group (OVA specific IgE (25.42±2.51) ng/ml vs (18.07±1.07) ng/ml vs (1.47±0.26) ng/ml, IL-6 (123.30±18.86) pg/ml vs (63.49±11.29) pg/ml vs (16.87±3.29) pg/ml, TNF-ɑ (162.50±38.15) pg/ml vs (72.96±11.28) pg/ml vs (27.52±4.15) pg/ml, F values was 481.604, 138.277, 63.938, respectively, all P<0.001). HE staining showed that the nasal epithelial cells of NC group were intact and neatly arranged. Nasal mucosa epithelial cells were arranged in disorder in AR group, with tissue structure swelling. Partial shedding of nasal epithelial cells, mucosal basement membrane thickening, submucosal tissue interstitial edema, vasodilation and gland hyperplasia were found in ARE group. Conclusion: An increase inflammatory factors level such as IL-6 and TNF-ɑ aggravates pathological damage of nasal mucosa in a rat model of AR by exposure to PM2.5.

Abstract
Approximately 20% of Graves' disease (GD) patients may result eventually in hypothyroidism in their natural course. Uterus globulin-associated protein 1 (UGRP1) was associated with GD in our previous study. Here we investigated the role of UGRP1 in the development of autoimmune thyroid disease (AITD). The results showed that UGRP1 was expressed in the thyrocytes of most Hashimoto's thyroiditis (HT) patients and a proportion of GD patients (293 HT and 198 GD). The pathologic features of UGRP1-positive thyrocytes resembled "Hürthle cells", and were surrounded by infiltrated leukocytes. The positivity rate of TPOAb in UGRP1-positive GD patients was much higher than that in -negative GD patients. Moreover, UGRP1 was co-expressed with Fas and HLA-DR in the thyrocytes of AITD patients. We also found IL-1β but not Th1 or Th2 cytokines was able to upregulate the expression of UGRP1. Our findings indicated that UGRP1 may be a novel marker in thyrocytes to predict GD patients who develop hypothyroidism.

Abstract
Type 2 diabetes mellitus (T2DM) has become a prevalent health problem in China, especially in urban areas. Early prevention strategies are needed to reduce the associated mortality and morbidity. We applied the combination of rules and different machine learning techniques to assess the risk of development of T2DM in an urban Chinese adult population. A retrospective analysis was performed on 8000 people with non-diabetes and 3845 people with T2DM in Nanjing. Multilayer Perceptron (MLP), AdaBoost (AD), Trees Random Forest (TRF), Support Vector Machine (SVM), and Gradient Tree Boosting (GTB) machine learning techniques with 10 cross validation methods were used with the proposed model for the prediction of the risk of development of T2DM. The performance of these models was evaluated with accuracy, precision, sensitivity, specificity, and area under receiver operating characteristic (ROC) curve (AUC). After comparison, the prediction accuracy of the different five machine models was 0.87, 0.86, 0.86, 0.86 and 0.86 respectively. The combination model using the same voting weight of each component was built on T2DM, which was performed better than individual models. The findings indicate that, combining machine learning models could provide an accurate assessment model for T2DM risk prediction.

Abstract
Objective: To explore the effect of neurokinin-1 receptor small interfering RNA (NK-1R-siRNA) on the expression of inflammation factors in allergic rhinitis (AR). Methods: Twenty-four male SD rats were divided into three groups randomly (by random number table methord): NK-1R-siRNA group, negative control siRNA (NC-siRNA) group and saline group, with 8 rats in each group. SD rats were sensitized and challenged with ovalbumin (OVA) to induce AR. The rats were treated intranasally with NK-1R-siRNA, NC-siRNA or saline before and during the challenge period. The AR symptoms were observed. The levels of OVA-specific IgE were measured by enzyme-linked immunosorbent assay (ELISA). The levels of NK-1R expression in the nasal mucosal tissues were determined by real time PCR (RT-PCR) and immunohistochemistry. Antibody array was used in studying the expression of inflammation cell factors in nasal mucosa. SPSS 11.0 software was used for one-factor analysis of variance. Results: Compared with saline group, AR symptoms relived significantly in NK-1R-siRNA group (nose rubbing (31.4±8.9)/15 min vs (69.5±17.9)/15 min, sneezing (7.2±1.9)/15 min vs (23.7±9.2)/15 min, nasal secretions (7.1±2.3) mg vs (24.1±4.4) mg, t value was 38.100, 17.125, 16.837, respectively, all P<0.01), and the level of serum OVA-specific IgE was also reduced ((8.56±0.73) ng/ml vs (18.05±1.22) ng/ml, t=9.787, P<0.01). The RT-PCR and immunohistochemistry results showed that the expression of NK-1R in nasal mucosa of NK-1R-siRNA group was remarkably reduced than that of the NC-siRNA group and saline group. After the treatment of NK-1R-siRNA, the expression of interleukin (IL) 1α, IL-1β, IL-4, IL-6 and IL-13 decreased, while the interferon-γ (IFN-γ) and IL-10 increased. Conclusion: NK-1R-siRNA could regulate the release of inflammation factors in AR nasal mucosa, thus relive the allergic inflammation.

Abstract
PURPOSE Neoadjuvant chemoradiotherapy (neoCRT) is a standard treatment for locally advanced rectal cancer (LARC); however, resistance to chemoradiotherapy is one of the main obstacles to improving treatment outcomes. The goal of this study was to identify factors involved in the radioresistance of colorectal cancer and to clarify the underlying mechanisms. EXPERIMENTAL DESIGN A genome-wide RNAi screen was used to search for candidate radioresistance genes. After RFC4 knockdown or overexpression, colorectal cancer cells exposed to X-rays both in vitro and in a mouse model were assayed for DNA damage, cytotoxicity, and apoptosis. Moreover, the regulatory effects and mechanisms of RFC4 in DNA repair were investigated in vitro. Finally, the relationships between RFC4 expression and clinical parameters and outcomes were investigated in 145 patients with LARC receiving neoCRT. RESULTS RFC4, NCAPH, SYNE3, LDLRAD2, NHP2, and FICD were identified as potential candidate radioresistance genes. RFC4 protected colorectal cancer cells from X-ray-induced DNA damage and apoptosis in vitro and in vivo. Mechanistically, RFC4 promoted nonhomologous end joining (NHEJ)-mediated DNA repair by interacting with Ku70/Ku80 but did not affect homologous recombination-mediated repair. Higher RFC4 expression in cancer tissue was associated with weaker tumor regression and poorer prognosis in patients with LARC treated with neoCRT, which likely resulted from the effect of RFC4 on radioresistance, not chemoresistance. CONCLUSIONS RFC4 was identified as a radioresistance factor that promotes NHEJ-mediated DNA repair in colorectal cancer cells. In addition, the expression level of RFC4 predicted radiotherapy responsiveness and the outcome of neoadjuvant radiotherapy in patients with LARC.

Abstract
Objective: To compare the etiological constitution of recurrent miscarriage (RM) between patients with consecutive two and three or more miscarriages through combining the routine examination results and embryonic karyotype. Methods: Patients with a history of two or more consecutive clinical miscarriages (≤12 weeks of gestation) consulting in the RM clinic of the First Affiliated Hospital of Sun Yat-sen University from March 2011 to January 2016 were collected. Six hundred and ninety-six with detailed history recorded, routine clinical examinations of RM and at least once embryonic karyotype were ultimately enrolled in this study. Their etiological constitution of RM were analyzed in groups of consecutive two and three or more miscarriage. The etiologies of RM in analysis consisted of women age, body mass index (BMI) , chromosome abnormalities of couples, uterine abnormalities, endocrinology abnormalities and antiphospholipid syndrome (APS) . Results: (1) Among 696 patients, the abnormal embryonic karyotypes was 60.6% (422/696) and routine RM etiologies was 32.2% (224/696) , leaving the ratio of unexplained RM was only 29.0% (202/696). (2) A total of 717 embryo karyotype were found in 696 patients, included21 cases with twice embryo karyotype results the percentage of normal embryo was 39.7% (285/717) , while abnormal ones was 60.3% (432/717). Among the types of abnormal karyotype, the most common ones (>10%) were trisomy 16 (19.2%, 83/432) , monosome X (11.3%, 49/432) and trisomy 22 (10.9%, 47/432). (3) Among the 696 RM patients, the number of two and three or more miscarriages were respectively 446 (64.1%, 446/696) and 250 (35.9%, 250/696). Comparing groups of three or more miscarriages with two miscarriages, there were significant differencein older age as well as uterine adhesion (P<0.05). But no difference was found in body mass index (BMI) , the rates of chromosome abnormalities of couples, uterine abnormalities except uterine adhesion, endocrinology abnormalities and APS (all P>0.05) between two groups. Conclusions: The abnormal embryonic karyotype is the most common cause of first-trimester RM. The etiological constitution of two and three or more recurrent miscarriages is accordant, suggesting that routine clinical examination and the embryonic karyotype should be started following two consecutive clinical early miscarriages.

Abstract
AIM To evaluate indoleamine-2,3-dioxygenase 1/cyclooxygenase 2 (IDO1/COX2) expression as an independent prognostic biomarker for colorectal cancer (CRC) patients.
METHODS We retrospectively studied the medical records of 95 patients who received surgical resection from August 2008 to January 2010. All patients were randomly assigned to adjuvant treatment with or without celecoxib groups after surgery. We performed standard immunohistochemistry to assess the expression levels of IDO1/COX2 and evaluated the correlation of IDO1/COX2 with clinicopathological factors and overall survival (OS) outcomes.
RESULTS The expression of nuclear IDO1 was significantly correlated with body mass index (P < 0.001), and IDO1 expression displayed no association with sex, age, tumor differentiation, T stage, N stage, carcinoembryonic antigen, cancer antigen 19-9, CD3+ and CD8+ tumor infiltrating lymphocytes, and COX2. In univariate analysis, we found that nuclear IDO1 (P = 0.039), nuclear/cytoplasmic IDO1 [hazard ratio (HR) = 2.044, 95% confidence interval (CI): 0.871-4.798, P = 0.039], nuclear IDO1/COX2 (HR = 3.048, 95%CI: 0.868-10.7, P = 0.0049) and cytoplasmic IDO1/COX2 (HR = 2.109, 95%CI: 0.976-4.558, P = 0.022) all yielded significantly poor OS outcomes. Nuclear IDO1 (P = 0.041), nuclear/cytoplasmic IDO1 (HR = 3.023, 95%CI: 0.585-15.61, P = 0.041) and cytoplasmic IDO1/COX2 (HR = 2.740, 95%CI: 0.764-9.831, P = 0.038) have significantly poor OS outcomes for the CRC celecoxib subgroup. In our multivariate Cox model, high coexpression of cytoplasmic IDO1/COX2 was found to be an independent predictor of poor outcome in CRC (HR = 2.218, 95%CI: 1.011-4.48, P = 0.047) and celecoxib subgroup patients (HR = 3.210, 95%CI: 1.074-9.590, P = 0.037).
CONCLUSION Our results showed that cytoplasmic IDO1/COX2 coexpression could be used as an independent poor predictor for OS in CRC.

Abstract
Vitexin, a flavonoids compound, is known to exhibit broad anti-oxidative, anti-inflammatory, analgesic, and antitumor activity in many cancer xenograft models and cell lines. The purpose of this study was to investigate the antitumor effects and underlying mechanisms of vitexin on hepatocellular carcinoma. In this study, we found that vitexin suppressed the viability of HCC cell lines (SK-Hep1 and Hepa1-6 cells) significantly. Vitexin showed cytotoxic effects against HCC cell lines in vitro by inducing apoptosis and inhibiting autophagy. Vitexin induced apoptosis in a concentration-dependent manner, and caused up-regulations of Caspase-3, Cleave Caspase-3, and a down-regulation of Bcl-2. The expression of autophagy-related protein LC3 II was significantly decreased after vitexin treatment. Moreover, western blot analysis presented that vitexin markedly up-regulated the levels of p-JNK and down-regulated the levels of p-Erk1/2 in SK-Hep1 cells and Hepa1-6 cells. Cotreatment with JNK inhibitor SP600125, we demonstrated that apoptosis induced by vitexin was suppressed, while the inhibition of autophagy by vitexin was reversed. The results of colony formation assay and mouse model confirmed the growth inhibition role of vitexin on HCC in vitro and in vivo. In conclusion, vitexin inhibits HCC growth by way of apoptosis induction and autophagy suppression, both of which are through JNK MAPK pathway. Therefore, vitexin could be regarded as a potent therapeutic agent for the treatment of HCC.

Abstract
The prognostic values of IRF-1 and Ki-67 for liver transplantation (LT) of hepatocellular carcinoma (HCC) were investigated, as well as the mechanisms of IRF-1 in tumor suppression. Adult orthotropic liver transplantation cases (N = 127) were involved in the analysis. A significant decreased recurrence free survival (RFS) was found in the Ki-67 positive groups. Ki-67, tumor microemboli, the Milan and UCSF criteria were found to be independent risk factors for RFS. In LT for HCC beyond the Milan criteria, a significant decrease in RFS was found in the IRF-1 negative groups. In SK-Hep1 cells, an increase in apoptosis and decrease in autophagy were observed after IFN-γ stimulation, which was accompanied with increasing IRF-1 levels. When IRF-1 siRNA or a caspase inhibitor were used, reductions in LC3-II were diminished or disappeared after IFN-γ stimulation, suggesting that IFN-γ inhibited autophagy via IRF-1 expression and caspase activation. However, after IRF-1 siRNA was introduced, a reduction in LC3-II was found. Thus basic expression of IRF-1 was also necessary for autophagy. IRF-1 may be used as a potential target for HCC treatment based on its capacity to affect apoptosis and autophagy. Ki-67 shows great promise for the prediction of HCC recurrence in LT and can be used as an aid in the selection of LT candidates.

Abstract
The present study was designed to investigate the prognostic significance of the preoperative sensitive-modified Glasgow prognostic score (S-mGPS) and its superiority in esophageal squamous cell carcinoma (ESCC). Clinicopathologic characteristics, preoperative albumin and C-reactive protein (CRP) levels were retrospectively collected in 442 patients who underwent transthoracic esophagectomy. The S-mGPS was calculated before surgery based on optimal cutoff values of 45.6 g/L for albumin and 10.0 mg/L for CRP. 360, 74 and 8 cases were assigned an mGPS of 0, 1 and 2, respectively. In contrast, the S-mGPS was 0 in 114, 1 in 258 and 2 in 70 patients. Of the 360 patients with an mGPS of 0, 246 migrated to the S-mGPS-1 group. Both mGPS and S-mGPS were significantly correlated with tumor length, depth of invasion, pathological tumor-node-metastasis (pTNM) stage and adjuvant treatment. In addition, they were significantly associated with disease free survival (DFS) and overall survival (OS) in univariate analysis. Furthermore, multivariate Cox regression analysis identified S-mGPS as an independent prognostic indicator for both DFS [hazard ratio (HR), 1.577; 95% confidence interval (CI), 1.149-2.163; P = 0.005] and OS (HR, 1.762; 95% CI, 1.250-2.484; P = 0.001), but not mGPS (HR, 0.957; 95% CI, 0.692-1.323; P = 0.790 for DFS and HR, 1.089; 95% CI, 0.781-1.517; P = 0.615 for OS, respectively). Moreover, subgroup analysis revealed that the prognostic impact of the S-mGPS was especially striking in pTNM stage II patients. The preoperative S-mGPS is superior to the mGPS as a prognostic predictor in patients with resectable ESCC.

Abstract
The present study was to establish a prognostic indicator based on preoperative fibrinogen and C-reactive protein (CRP) (FC score) in esophageal squamous cell carcinoma (ESCC). Clinicopathologic characteristics, preoperative plasma fibrinogen and serum CRP levels were reviewed in patients who underwent transthoracic esophagectomy. The optimal cut-off value for fibrinogen and CRP was defined as 4.0 g/dL and 10.0 mg/L according to previous reports. Patients with elevated fibrinogen and CRP levels were assigned a score of 2, those with only one of these two abnormalities were allocated a score of 1, and those with neither of the two abnormalities were assigned a score of 0. Preoperative FC score was significantly correlated with degree of differentiation, depth of invasion, tumor-node-metastasis (TNM) stage and modified Glasgow Prognostic Score (mGPS). No significant differences in age, gender, tumor length, tumor location, lymph node status or smoking were identified between groups. Univariate survival analysis demonstrated that high preoperative FC score (1/2) was significantly associated with impaired disease free survival (DFS) [hazard ratio (HR), 1.650; 95% confidence interval (CI), 1.181-2.303; P = 0.003] and overall survival (OS) (HR, 1.879; 95% CI, 1.333-2.648; P<0.001), and it remained an independent predictor for both DFS (HR, 1.468; 95% CI, 1.043-2.067; P=0.028) and OS (HR, 2.070; 95% CI, 1.266-3.385; P=0.004) in multivariate Cox regression analysis. Preoperative FC score might represent a new potential marker of worst prognosis that warrants further evaluation in prospective and large cohort studies among ESCC patients who underwent transthoracic esophagectomy.

Abstract
Highly upregulated in liver cancer (HULC), a lncRNA that is considered a key molecule in human liver cancer, has recently been revealed to be involved in hepatocellular carcinoma (HCC) development and progression [1, 2]. It has been reported that HULC can promote tumor invasion and metastasis of HCC, but its function and mechanism of action in HCC have not been elucidated. In this study, we found that HULC was aberrantly up-regulated in HCC tissues and associated with TNM stage, intrahepatic metastases, HCC recurrence, and postoperative survival. HULC depletion inhibited the growth and metastasis of HCC cell lines in vitro and in vivo. Moreover, HULC contributes to ZEB1-induced epithelial-mesenchymal transition (EMT), a requirement for tumor invasion and metastasis that plays a key role in cancer progression. This effect of ZEB1 was inhibited by HULC siRNA. We conclude that the HULC functioned as a competing endogenous RNA (ceRNA) to mediate EMT via up-regulating ZEB1. In this way, it sequesters the miR-200a-3p signaling pathway to facilitate HCC metastasis. HULC comes into play as an oncogene in HCC, acting mechanistically by inducing HCC cells to activate EMT. Such an effect promotes tumor progression and metastasis through the miR-200a-3p/ZEB1 signaling pathway. The identification of this novel pathway that links high expression levels of HULC with EMT in HCC cells may serve as the foundation for the development of novel anti-tumor therapeutics.

Abstract
Nearly 20% patients with stage II A colon cancer will develop recurrent disease post-operatively. The present study aims to develop a scoring system based on Artificial Neural Network (ANN) model for predicting 10-year survival outcome. The clinical and molecular data of 117 stage II A colon cancer patients from Sun Yat-sen University Cancer Center were used for training set and test set; poor pathological grading (score 49), reduced expression of TGFBR2 (score 33), over-expression of TGF-β (score 45), MAPK (score 32), pin1 (score 100), β-catenin in tumor tissue (score 50) and reduced expression of TGF-β in normal mucosa (score 22) were selected as the prognostic risk predictors. According to the developed scoring system, the patients were divided into 3 subgroups, which were supposed with higher, moderate and lower risk levels. As a result, for the 3 subgroups, the 10-year overall survival (OS) rates were 16.7%, 62.9% and 100% (P < 0.001); and the 10-year disease free survival (DFS) rates were 16.7%, 61.8% and 98.8% (P < 0.001) respectively. It showed that this scoring system for stage II A colon cancer could help to predict long-term survival and screen out high-risk individuals for more vigorous treatment.

Abstract
Approximately 30% of locally advanced rectal cancer patients might not benefit from chemoradiotherapy; however, the response to neoadjuvant chemoradiotherapy in these cases is difficult to predict. Pim-3 is a member of the provirus integration site for a moloney murine leukemia virus family of proteins that contributes to cell proliferation, survival, and chemotherapy resistance. Therefore, the relationship between Pim-3 expression and response to neoadjuvant chemoradiotherapy in rectal cancer patients is important to evaluate. 175 rectal cancer patients who underwent neoadjuvant treatment enrolled in this study. The relationship between Pim-3 expression on immunohistochemical analysis of rectal cancer tissue, which was obtained before treatment, the response to chemoradiotherapy and survival was investigated. The patients with no Pim-3 expression were more likely to achieve a pathologic complete response to chemoradiotherapy than patients with Pim-3 expression (P = 0.001). Cox multivariate analysis showed that the significant prognostic factors were Pim-3 expression (P = 0.003) and the number of neoadjuvant chemotherapy cycles (P = 0.005) for overall survival. Neoadjuvant chemotherapy cycles (P = 0.007), adjuvant chemotherapy cycles (P = 0.004) and pathology types (P = 0.049) were significant prognostic factors for disease-free survival. Pim-3 is a potential predictive biomarker for the response of rectal cancer to chemoradiotherapy.

Abstract
BACKGROUND The concept of maintenance therapy in cancer treatment is currently under debate because of modest survival benefits, added toxicity, economic considerations, and quality-of-life concerns. Traditional Chinese Medicine (tcm) is widely used in China for cancer patients, offering the advantages of low toxicity and enhancement of quality of life. However, no systematic reviews or meta-analyses have assessed the role of tcm as maintenance treatment for non-small-cell lung carcinoma. METHODS We searched the Chinese Biomedical Literature Database, the China National Knowledge Infrastructure, PubMed, embase, and the Cochrane Library databases for all eligible studies. The endpoints were overall survival (os), progression-free survival (pfs), the 1-year and 2-year survival rates, and performance status. Our meta-analysis used a fixed-effects model and a random-effects model for heterogeneity in the Stata software application (version 11.0: StataCorp LP, College Station, TX, U.S.A.), with the results expressed as hazard ratios (hrs) or risk ratios (rrs), with their corresponding 95% confidence intervals (95% cis). RESULTS Sixteen randomized studies representing 1150 patients met the inclusion criteria. Compared with best supportive care, observation, or placebo, tcm as maintenance treatment was associated with a significant increase in os (hr: 0.49; 95% ci: 0.35 to 0.68; p < 0.001), pfs (hr: 0.66; 95% ci: 0.51 to 0.84; p = 0.001), and 2-year survival rate (rr: 0.63; 95% ci: 0.44 to 0.92, p = 0.017), and a significant improvement in performance status (rr: 0.68; 95% ci: 0.61 to 0.75; p < 0.001). CONCLUSIONS For patients who show non-progression-including stable disease, partial response, or complete response-after first-line chemotherapy, including those with poor quality of life, oral Chinese herbal medicine can be considered an efficient and safe maintenance therapy strategy.

Abstract
The majority of colorectal cancers (CRCs) are hormone‑dependent. Thus, endocrine therapy has become an attractive strategy to treat CRC. The aim of the present study was to investigate the inhibitory effect of combined tamoxifen (TAM) plus β‑estradiol (E2) treatment on human DLD‑1 CRC cells. The human DLD‑1 CRC cell line was treated with different concentrations of TAM, β‑estradiol, or a combination of these two agents. Cell viability was assessed using an MTT assay, while apoptosis was detected using flow cytometry analysis. Alterations in the RNA and protein levels of the apoptosis‑associated factors cyclin D1 and survivin were measured in the treated DLD‑1 cells using semi‑quantitative polymerase chain reaction (sqPCR) and western blot analyses. Alterations in cellular migration ability were monitored using a Transwell migration assay. Treatment with TAM, β‑estradiol and TAM plus β‑estradiol inhibited DLD‑1 cell viability. The flow cytometry results revealed that these drugs promoted cell apoptosis, and the Transwell migration assay results indicated that the reduction in cell migration was greater in the TAM+E2 treatment group when compared with each treatment alone. sqPCR and western blot analysis results demonstrated that TAM, E2 and a combination of the two affected survivin expression based on the drug concentration and the treatment duration; however, they demonstrated no significant effect on cyclin D1 expression. In conclusion, treatment of DLD‑1 cells with TAM, β‑estradiol, or a combination of these two drugs, inhibited cell viability and migration, promoted cell apoptosis, and reduced the mRNA and protein expression levels of survivin in a dose‑ and time‑dependent manner. These results provide novel experimental basis for hormonal adjuvant therapy for the treatment of CRC.

Abstract
PURPOSE The safety and efficacy of intraoperative chemotherapy in colorectal cancer have not yet been extensively investigated. This randomized control trial was designed to compare the safety and efficacy of intraoperative chemotherapy in combination with surgical resection to those of traditional surgical resection alone. METHODS From January 2011 to January 2016, 696 colorectal cancer patients were enrolled in this study: 341 patients were randomly assigned to the intraoperative chemotherapy, which consist of portal vein chemotherapy, intraluminal chemotherapy and intraperitoneal chemotherapy, plus surgery group, whereas 344 patients were randomized to the control group to undergo surgery alone. Eleven patients withdrew consent. RESULTS Intraoperative chemotherapy did not increase the rate of surgical complications, and no severe chemotherapy-associated side effects were observed. Four patients in each of the intraoperative chemotherapy and the control groups experienced anastomotic leakage and underwent a second operation (1.2 vs. 1.2%, P = 0.99). There were no deaths within 90 days after surgery in the chemotherapy group, whereas one patient died in the control group. Intraoperative chemotherapy did not decrease the rate of patients who received postoperative chemotherapy between the intraoperative group and control group (29.3 vs. 30.2%, P = 0.795). CONCLUSIONS Intraoperative chemotherapy can be safely performed during colorectal surgery; however, follow-up is necessary for a better assessment of its efficacy.

Abstract
Background It is still under debate that whether stage IV colorectal cancer patients with unresectable metastasis can benefit from primary tumor resection, especially for asymptomatic colorectal cancer patients. Retrospective studies have shown controversial results concerning the benefit from surgery. This retrospective study aims to evaluate whether the site of primary tumor is a predictor of palliative resection in asymptomatic stage IV colorectal cancer patients. Methods One hundred ninety-four patients with unresectable metastatic colorectal cancer were selected from Sun Yat-sen University Cancer Center Database in the period between January 2007 and December 2013. All information was carefully reviewed and collected, including the treatment, age, sex, carcinoembryonic antigen, site of tumor, histology, cancer antigen 199, number of liver metastases, and largest diameter of liver metastasis. The univariate and multivariate analyses were used to detect the relationship between primary tumor resection and overall survival of unresectable stage IV colorectal cancer patients. Results One hundred twenty-five received palliative resection, and 69 received only chemotherapy. Multivariate analysis indicated that primary tumor site was one of the independent factors (RR 0.569, P = 0.007) that influenced overall survival. For left-side colon cancer patients, primary tumor resection prolonged the median overall survival time for 8 months (palliative resection vs. no palliative resection: 22 vs. 14 months, P = 0.009); however, for right-side colon cancer patients, palliative resection showed no benefit (12 vs. 10 months, P = 0.910). Conclusions This study showed that left-side colon cancer patients might benefit from the primary tumor resection in terms of overall survival. This result should be further explored in a prospective study.

Abstract
The aim of this study is to explore the phenotypic and genotypic features of X-linked Charcot-Marie-Tooth (CMT) disease in the mainland of China and to study the cellular effects of six novel Gap junction protein beta-1 variants. We identified 25 missense and 1 non-sense mutations of GJB1 in 31 unrelated families out of 226 CMT families. The frequency of GJB1 mutations was 13.7% of the total and 65% of intermediate CMT. Six novel GJB1 variants (c.5A>G, c.8G>A, c.242T>C, c.269T>C, c.317T>C and c.434T>G) were detected in six unrelated intermediate CMT families. Fluorescence revealed that HeLa cells transfected with EGFP-GJB1-V74M, EGFP-GJB1-L81P or EGFP-GJB1-L90P had diffuse endoplasmic reticulum staining, HeLa cells transfected with EGFP-GJB1-L106P had diffuse intracellular staining, and HeLa cells transfected with EGFP-GJB1-N2S had cytoplasmic and nuclear staining. The distribution of Cx32 in HeLa cells transfected with EGFP-GJB1-F145C was similar to that of those transfected with wild-type (WT). These six variants resulted in a higher percentage of apoptosis than did WT as detected by flow cytometry and Hoechst staining. In conclusion, mutation screening should be first performed in intermediate CMT patients, especially those with additional features. The novel GJB1 variants c.5A>G, c.8G>A, c.242T>C and c.269T>C are considered pathogenic, and c.317T>C and c.434T>G are classified as probably pathogenic.

Abstract
Background Laparoscopic hepatectomy for hepatocellular carcinoma (HCC) located in segment VI, VII, or VIII of the liver is usually difficult because of poor operative exposure, due to the unique anatomical structure. In this study, we evaluated the practice of laparoscopic hepatectomy with the left jackknife position for patients with HCC located in segment VI, VII, or VIII. Methods A total of 10 patients were enrolled to undergo laparoscopic hepatectomy with the left jackknife position. Tumors located in segment VI, VII, or VIII were assessed by preoperative dynamic computed tomography or magnetic resonance imaging. Operation time, intraoperative blood loss, postoperative fasting time, postoperative drainage time, major postoperative complications, and duration of postoperative hospital stay were recorded. Results All surgeries were successfully completed. None of the patients required conversion to open surgery during the procedure, and no serious postoperative complications were observed. The median tumor size was 31 mm (range 23–41 mm) in diameter, the mean operation time was 166 ± 38 min, the mean intraoperative blood loss was 220 ± 135 mL, and the median postoperative hospital stay was 4 days (range 2–7 days). Conclusions For HCC located in segment VI, VII, or VIII, laparoscopic hepatectomy with this novel position—the left jackknife position—is safe and effective during tumor resection by exposing a sufficient operating field.

Abstract
The present study was aimed to investigate the effect of dihydroartemisinin on the colon cancer cell proliferation and apoptosis. The results from MTT assay revealed a concentration and time dependent relation between the inhibition of SW 948 cell viability and dihydroartemisinin addition. The viability of SW 948 cells was reduced to 45 and 24% on treatment with 30 and 50 µM, respectively concentrations of dihydroartemisinin after 48 h. Morphological examination of SW 948 cells showed attainment of rounded shape and cluster formation on treatment with dihydroartemisinin. Western blot analysis showed a significant increase in the activation of caspase-3 and expression of cleaved PARP by dihydroartemisinin treatment. The activation of PPARγ was increased significantly in SW 948 cells by treatment with dihydroartemisinin. Compared to control, the migration potential of SW 948 cells was reduced significantly (p < 0.005) and the expression levels of MMP-2 and -9 inhibited by dihydroartemisinin at 50 µM concentration. In the dihydroartemisinin treatment group colon tumor formation was significantly inhibited on treatment with 20 mg/kg doses of dihydroartemisinin after 30 days. Therefore, dihydroartemisinin inhibits colon cancer growth by inducing apoptosis and increasing the expression of PPARγ. Thus dihydroartemisinin can be used for the treatment of colon cancer.

Abstract
Objective To observe the features of syndrome patterns of Chinese medicine (CM) in elderly human immunodeficiency virus/acquired immune deficiency syndrome ( HIV/AIDS) patients in Guangxi Zhuang Autonomous Region. Methods According to a case-control study, a clinical question- naire was designated in elderly HIV/AIDS patients older than 50 years and healthy examinees with age and sex match. Their syndrome information of CM were collected from designated medical institutions in Guangxi Zhuang Autonomous Region from October 2013 to April 2014. Analyses of syndrome factors were conducted using WF-I[A Diagnosis and Treatment System of Traditional Chinese Medicine (Auxilia- ry). The disease location of CM and nature of diseases were compared between elderly HIV/AIDS patients and the controls. The features of syndrome patterns of CM in elderly HIV/AIDS patients were summarized. Results A total of 417 elderly HIV/AIDS patients and 362 examinees were enrolled. In elderly patients with HIV/AIDS, established syndrome factors of disease nature were qi deficiency, yang deficiency, yin deficiency, blood deficiency, dampness, and phlegm , and established syndrome factors of disease loca- tion included Shen, Fei, Pi, and Gan. There were statistical differences in established syndrome factors of disease location or nature between elderly patients with HIV/AIDS and the controls (P <0. 05). Conclu- sions Elderly HIV/AIDS patients were characterized by deficiency of qi, yang, yin, and blood in Shen, Fei, Pi, and Gan, as well as endogenous production of pathogenic factors such as dampness and phlegm. Intermingled deficiency and excess was dominated in elderly HIV/AIDS patients, and mainly man- ifested as deficiency syndrome.
